and agreements contained in all such Credit Documents (all such principal, premium, interest, reimbursement obligations, liabilities, indebtedness and obligations being herein collectively called the “Credit Document Obligations”);

Subsidiaries under any Designated Interest Rate Protection Agreement or Designated Treasury Services Agreement, whether now in existence or hereafter arising, and the due performance and compliance by such Borrower and such Subsidiaries with all of
the terms, conditions and agreements contained in each Designated Interest Rate Protection Agreement or Designated Treasury Services Agreement to which it is a party (all such obligations, liabilities and indebtedness being herein collectively

Obligations.

 2. Bankruptcy. Additionally, each Guarantor, jointly and severally, unconditionally
and irrevocably guarantees the payment of any and all of its Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by any Borrower or any such other Guaranteed Party upon the occurrence in respect of any Borrower or any
such other Guaranteed Party of any of the events specified in Section 11.05 of the Credit Agreement, and irrevocably and unconditionally, jointly and severally, promises to pay such Guaranteed Obligations to the Guaranteed Creditors, or order,
on demand, in lawful money of the United States 
 3. Nature of Liability. This Guaranty shall constitute a guaranty of payment, and
not of collection. The liability of each Guarantor hereunder is primary, absolute, joint and several, and unconditional and is exclusive and independent of any security for or other guaranty of the Guaranteed Obligations, whether executed by such
Guarantor, any other Guarantor, any other guarantor or by any other party, and, to the fullest extent permitted under law, the liability of each Guarantor hereunder shall not be affected or impaired by: (a) any direction as to application of
payment by any Borrower, any other Guaranteed Party or any other party, (b) any other continuing or other guaranty, undertaking or maximum liability of a Guarantor or of any other party as to the Guaranteed Obligations, (c) any payment on
or in reduction of any such other guaranty or undertaking (other than payment of the Guaranteed Obligations in cash), (d) any dissolution, termination or increase, decrease or change in personnel by any Borrower or any other Guaranteed Party,
(e) any payment made to any Guaranteed Creditor on the Guaranteed Obligations which any Guaranteed Creditor repays pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each
Guarantor waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding, (f) any action or inaction by the Guaranteed Creditors as contemplated in Section 6 hereof or
(g) any invalidity, irregularity or unenforceability of all or any part of the Guaranteed Obligations or of any security therefor. 

4. Independent Obligations. The obligations of each Guarantor hereunder are independent of the obligations of any other Guarantor, any
other guarantor, any Borrower or any other Guaranteed Party, and a separate action or actions may be brought and prosecuted against each Guarantor whether or not action is brought against any other Guarantor, any other guarantor, any Borrower or any
other Guaranteed Party and whether or not any other Guarantor, any other guarantor, any Borrower or any other Guaranteed Party be joined in any such action or actions. Each Guarantor waives, to the fullest extent permitted by law, the benefits of
any statute of limitations affecting its liability hereunder or the enforcement thereof. Any payment by any Borrower or any other Guaranteed Party or other circumstance which operates to toll any statute of limitations as to any Borrower or any such
other Guaranteed Party shall operate to toll the statute of limitations as to each Guarantor. 
 5. Certain Waivers. To the fullest
extent permitted under applicable law, each Guarantor hereby waives notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waives promptness, diligence, presentment, demand of payment, protest, notice of
dishonor or nonpayment of any such liabilities, suit or taking of other action by the Administrative Agent or any other Guaranteed Creditor against, and any other notice to, any party liable thereon (including such Guarantor, any other Guarantor,
any other guarantor, any Borrower or any other Guaranteed Party). 

  
 -3- 

 6. Authorization. Any Guaranteed Creditor may at any time and from time to time
without the consent of, or notice to, any Guarantor (except as shall be required by applicable statute and cannot be waived), without incurring responsibility to such Guarantor, without impairing or releasing the obligations of such Guarantor
hereunder, upon or without any terms or conditions and in whole or in part: 
 (a) change the manner, place or terms of
payment of, and/or change, increase or extend the time of payment of, renew or alter, any of the Guaranteed Obligations (including any increase or decrease in the rate of interest or fees thereon or the principal amount thereof), any security
therefor, or any liability incurred directly or indirectly in respect thereof, and this Guaranty shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered; 

(b) take and hold security for the payment of the Guaranteed Obligations and sell, exchange, release, surrender, impair,
realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed Obligations or any liabilities (including any of those hereunder)
incurred directly or indirectly in respect thereof or hereof, and/or any offset there against; 
 (c) exercise or refrain
from exercising any rights against any Borrower, any other Guaranteed Party, any other Credit Party, any Subsidiary thereof or otherwise act or refrain from acting;

other obligors; 
 (e) settle or compromise any of the Guaranteed Obligations, any security therefor or any liability
(including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of any Borrower or any other Guaranteed
Party to creditors of such Borrower or such other Guaranteed Party other than the Guaranteed Creditors; 
 (f) except as
otherwise expressly required by the Security Documents, apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of any Borrower or any other Guaranteed Party to the Guaranteed Creditors regardless of what liabilities
of such Borrower or such other Guaranteed Party remain unpaid; 
 (g) consent to or waive any breach of, or any act, omission
or default under, any of the Designated Interest Rate Protection Agreements, the Designated Treasury Services Agreements, the Credit Documents or any of the instruments or agreements referred to therein, or otherwise amend, modify or supplement any
of the Designated Interest Rate Protection Agreements, the Designated Treasury Services Agreements and the Credit Documents or any of such other instruments or agreements; 

  
 -4- 

 (h) act or fail to act in any manner which may deprive such Guarantor of its
right to subrogation against any Borrower or any other Guaranteed Party to recover full indemnity for any payments made pursuant to this Guaranty; and/or 

(i) take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable
discharge of such Guarantor from its liabilities under this Guaranty. 
 7. Continuing Guaranty. This Guaranty is a continuing one
and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. No failure or delay on the part of any Guaranteed Creditor in exercising any right, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which any Guaranteed Creditor would otherwise have. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any
other further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Guaranteed Creditor to any other or further action in any circumstances without notice or demand. It is not necessary for any Guaranteed
Creditor to inquire into the capacity or powers of any Borrower or any other Guaranteed Party or the officers, directors, partners or agents acting or purporting to act on its or their behalf, and any Guaranteed Obligations made or created in
reliance upon the professed exercise of such powers shall be guaranteed hereunder. 
 8. Subordination. Any indebtedness of any
Borrower or any other Guaranteed Party now or hereafter owing to any Guarantor is hereby subordinated to the Guaranteed Obligations of such Borrower or such other Guaranteed Party to the Guaranteed Creditors, and such Guaranteed Obligations of such
Borrower or such other Guaranteed Party to any Guarantor, if the Administrative Agent or the Collateral Agent, after the occurrence and during the continuance of an Event of Default, so requests, shall be collected, enforced and received by such
Guarantor for the benefit of the Guaranteed Creditors and be paid over to the Guaranteed Creditors on account of the Guaranteed Obligations of such Borrower or such other Guaranteed Parties to the Guaranteed Creditors, but without affecting or
impairing in any manner the liability of such Guarantor under the other provisions of this Guaranty. Without limiting the generality of the foregoing, each Guarantor hereby agrees with the Guaranteed Creditors that it will not exercise any right of
subrogation which it may at any time otherwise have as a result of this Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until all Guaranteed Obligations have been irrevocably paid in full in cash. 

9. Waiver and Maximum Liability. (a) Each Guarantor waives any right (except as shall be required by applicable law and cannot be
waived) to require the Guaranteed Creditors to: (i) proceed against any Borrower, any other Guaranteed Party, any other Guarantor, any other guarantor of the Guaranteed Obligations or any other party; (ii) proceed against or exhaust any
security held from any Borrower, any other Guaranteed Party, any other Guarantor, any other guarantor of the Guaranteed Obligations or any other party; or (iii) pursue any other remedy in the Guaranteed Creditors’ power whatsoever. Each
Guarantor waives any defense (except as shall be required by applicable statute and cannot be waived) based on or 

  
 -5- 

 arising out of any defense of any Borrower, any other Guaranteed Party, any other Guarantor, any other
guarantor of the Guaranteed Obligations or any other party other than payment in full of the Guaranteed Obligations including, without limitation, any defense based on or arising out of the disability of any Borrower, any other Guaranteed Party, any
other Guarantor, any other guarantor of the Guaranteed Obligations or any other party, or the invalidity, illegality or unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the
liability of any Borrower or any other Guaranteed Party other than payment in full of the Guaranteed Obligations. The Guaranteed Creditors may, at their election, foreclose on any security held by the Administrative Agent, the Collateral Agent or
the other Guaranteed Creditors by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the extent such sale is permitted by applicable law), or exercise any other right or remedy the
Guaranteed Creditors may have against any Borrower, any other Guaranteed Party or any other party, or any security, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Guaranteed Obligations
have been paid in full. Each Guarantor waives, to the fullest extent permitted under law, any defense arising out of any such election by the Guaranteed Creditors, even though such election operates to impair or extinguish any right of reimbursement
or subrogation or other right or remedy of such Guarantor against any Borrower, any other Guaranteed Party or any other party or any security. 

(b) Each Guarantor waives, to the fullest extent permitted under law, all presentments, demands for performance, protests and notices,
including, without limitation, notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Guaranty, and notices of the existence, creation or incurring of new or additional Guaranteed Obligations. Each
Guarantor assumes all responsibility for being and keeping itself informed of each Borrower’s and each other Guaranteed Party’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the
Guaranteed Obligations and the nature, scope and extent of the risks which such Guarantor assumes and incurs hereunder, and agrees that the Guaranteed Creditors shall have no duty to advise any Guarantor of information known to them regarding such
circumstances or risks. 
 10. Enforcement. The Guaranteed Creditors agree that this Guaranty may be enforced only by the action of
the Administrative Agent or the Collateral Agent, in each case acting upon the instructions of the Required Lenders (or, after the date on which all Credit Document Obligations have been paid in full, the holders of at least a majority of the
outstanding Other Obligations) and that no other Guaranteed Creditors shall have any right individually to seek to enforce or to enforce this Guaranty, it being understood and agreed that such rights and remedies may be exercised by the
Administrative Agent or the Collateral Agent or, after all the Credit Document Obligations have been paid in full, by the holders of at least a majority of the outstanding Other Obligations, as the case may be, for the benefit of the Guaranteed
Creditors upon the terms of this Guaranty. The Guaranteed Creditors further agree that this Guaranty may not be enforced against any director, officer, employee, partner, member or stockholder of any Guarantor (except to the extent such partner,
member or stockholder is also a Guarantor hereunder).

Adverse Effect) or (iii) violate any provision of the certificate or articles of incorporation, certificate of formation, limited liability company agreement or by-laws (or equivalent organizational
documents), as applicable, of such Guarantor or any of its Restricted Subsidiaries.

reasonably be expected to have a Material Adverse Effect, no order, consent, approval, license, authorization or validation of, or filing, recording or registration with (except for (x) those that have otherwise been obtained or made on or prior to

Guaranteed Creditor other than the Administrative Agent). For the purpose of this Guaranty, the term “Class” shall mean each class of Guaranteed Creditors, i.e., whether (x) the Lender Creditors as holders of the Credit
Document Obligations or (y) the Other Creditors as the holders of the Other Obligations. For the purpose of this Guaranty, the term “Requisite Creditors” of any Class shall mean (x) with respect to the Credit Document

then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon such Guarantor, notwithstanding any revocation hereof or other instrument evidencing any liability of any Borrower or
any other Guaranteed Party, and such Guarantor shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such payee.

party at its address set forth in Section 18 hereof, such service to become effective 30 days after such mailing. Each Guarantor and each Guaranteed Creditor (by its acceptance of the benefits of this Guaranty) hereby
irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any action or proceeding commenced hereunder or under any other Credit Document to which it is a party that such service
of process was in any way invalid or ineffective. Nothing herein shall affect the right of any such party to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against any other party in any
other jurisdiction.

Guaranty or any other Credit Document to which such Guarantor is a party brought in the courts referred to in clause (a) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that such action or
proceeding brought in any such court has been brought in an inconvenient forum.

Lenders (or all the Lenders if required by Section 13.12 of the Credit Agreement)), such Guarantor shall upon consummation of such sale or other disposition (except to the extent that such sale or disposition is to Holdings or another Credit
Party) be released from this Guaranty automatically and without further action and this Guaranty shall, as to each such Guarantor, terminate, and have no further force or effect (it being understood and agreed that the sale of one or more Persons
that own, directly or indirectly, all of the capital stock of any Guarantor shall be deemed to be a sale of such Guarantor for the purposes of this Section 21). Upon the occurrence of the Termination Date, this Guaranty shall automatically and
without further action, as to all Guarantors, terminate and have no further force and effect. The Administrative Agent will (and each Secured Creditor (by its acceptance of the benefits of this Guaranty) irrevocably authorizes the Administrative
Agent to), at the Guarantors’ expense, execute and deliver to the Guarantors such documents as the Guarantors may reasonably request to evidence, as applicable, the release of such Guarantor from, or the termination in full of, this Guaranty.

 22. Right of Contribution. At any time a payment in respect of the Guaranteed Obligations is made under this Guaranty, the right
of contribution of each Guarantor against each other Guarantor shall be determined as provided in the immediately following sentence, with the right of contribution of each Guarantor to be revised and restated as of each date on which a payment (a
“Relevant Payment”) is made on the Guaranteed Obligations under this Guaranty. At any time that a Relevant Payment is made by a Guarantor that results in the aggregate payments made by such Guarantor in respect of the Guaranteed
Obligations to and including the date of the Relevant Payment exceeding such Guarantor’s Contribution Percentage (as defined below) of the aggregate payments made by all Guarantors in respect of the Guaranteed Obligations to and including the
date of the Relevant Payment (such excess, the “Aggregate Excess Amount”), each such Guarantor shall have a right of contribution against each other Guarantor who has made payments in respect of the Guaranteed Obligations to and
including the date of the Relevant Payment in an aggregate amount less than such other Guarantor’s Contribution Percentage of the aggregate payments made to and including the date 

  
 -11- 

 of the Relevant Payment by all Guarantors in respect of the Guaranteed Obligations (the aggregate amount of
such deficit, the “Aggregate Deficit Amount”) in an amount equal to (x) a fraction the numerator of which is the Aggregate Excess Amount of such Guarantor and the denominator of which is the Aggregate Excess Amount of all
Guarantors multiplied by (y) the Aggregate Deficit Amount of such other Guarantor. A Guarantor’s right of contribution pursuant to the preceding sentences shall arise at the time of each computation, subject to adjustment to the time of
each computation; provided that no Guarantor may take any action to enforce such right until the Guaranteed Obligations have been paid in full, it being expressly recognized and agreed by all parties hereto that any Guarantor’s right of
contribution arising pursuant to this Section 22 against any other Guarantor shall be expressly junior and subordinate to such other Guarantor’s obligations and liabilities in respect of the Guaranteed Obligations and any other obligations
owing under this Guaranty. As used in this Section 22: (i) each Guarantor’s “Contribution Percentage” shall mean the percentage obtained by dividing (x) the Adjusted Net Worth (as defined below) of such Guarantor by
(y) the aggregate Adjusted Net Worth of all Guarantors; (ii) the “Adjusted Net Worth” of each Guarantor shall mean the greater of (x) the Net Worth (as defined below) of such Guarantor and (y) zero; and
(iii) the “Net Worth” of each Guarantor shall mean the amount by which the fair saleable value of such Guarantor’s assets on the date of any Relevant Payment exceeds its existing debts and other liabilities (including
contingent liabilities, but without giving effect to any Guaranteed Obligations arising under this Guaranty) on such date. Notwithstanding anything to the contrary contained above, any Guarantor that is released from this Guaranty shall thereafter
have no contribution obligations, or rights, pursuant to this Section 22, and at the time of any such release, if the released Guarantor had an Aggregate Excess Amount or an Aggregate Deficit Amount, same shall be deemed reduced to $0, and the
contribution rights and obligations of the remaining Guarantors shall be recalculated on the respective date of release (as otherwise provided above) based on the payments made hereunder by the remaining Guarantors. All parties hereto recognize and
agree that, except for any right of contribution arising pursuant to this Section 22, each Guarantor who makes any payment in respect of the Guaranteed Obligations shall have no right of contribution or subrogation against any other Guarantor
in respect of such payment until all of the Guaranteed Obligations have been paid in full. Each of the Guarantors recognizes and acknowledges that the rights to contribution arising hereunder shall constitute an asset in favor of the party entitled
to such contribution. In this connection, each Guarantor has the right to waive its contribution right against any Guarantor to the extent that after giving effect to such waiver such Guarantor would remain solvent, in the reasonable determination
of the Required Lenders. 
 23. Maximum Liability. Each Guarantor and each Guaranteed Creditor (by its acceptance of the benefits of
this Guaranty) hereby confirms that it is its intention that this Guaranty not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act of any similar Federal or state law. To
effectuate the foregoing intention, each Guarantor and each Guaranteed Creditor (by its acceptance of the benefits of this Guaranty) hereby irrevocably agrees that the Guaranteed Obligations guaranteed by such Guarantor shall be limited to such
amount as will, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Guarantor that are relevant under such laws and after giving effect to any rights to contribution pursuant to any agreement
providing for an equitable contribution among such Guarantor and the other Guarantors, result in the Guaranteed Obligations of such Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance. 

  
 -12- 

 24. Counterparts. This Guaranty may be executed in any number of counterparts and by
the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. A set of counterparts executed by all the parties
hereto shall be lodged with the Guarantors and the Administrative Agent. 
 25. Payments. All payments made by any Guarantor
hereunder will be made without setoff, counterclaim or other defense (other than payment in cash of such Guaranteed Obligations made in accordance with the terms of this Guaranty) and on the same basis as payments are made by the Borrowers under
Sections 5.03 and 5.04 of the Credit Agreement. 
 26. Additional Guarantors. It is understood and agreed that any Restricted
Subsidiary of the Lead Borrower that is required to become a party to this Guaranty after the date hereof pursuant to the requirements of the Credit Agreement or any other Credit Document, shall become a Guarantor hereunder by (x) executing and
delivering a counterpart hereof, or a joinder agreement substantially in the form of Exhibit A hereto, and delivering same to the Administrative Agent and (y) taking all actions as specified in this Guaranty as would have been taken by such
Guarantor had it been an original party to this Guaranty, in each case with all documents required by the Credit Documents to be delivered to the Administrative Agent and with all documents and actions required by the Credit Documents to be taken to
the reasonable satisfaction of the Administrative Agent. 
 27. Keepwell. Each Guaranteed Party that is a Qualified ECP Guarantor (as
defined below) at the time the Guaranty or the grant of the security interest under the Credit Documents, in each case, by any Specified Credit Party, becomes effective with respect to any Swap Obligation, hereby jointly and severally, absolutely,
unconditionally and irrevocably undertakes to provide such funds or other support to each Specified Loan Party with respect to such Swap Obligation as may be needed by such Specified Loan Party from time to time to honor all of its obligations under
this Guaranty and the other Credit Documents in respect of such Swap Obligation (but, in each case, only up to the maximum amount of such liability that can be hereby incurred without rendering such Qualified ECP Guarantor’s obligations and
undertakings under this Section 27 voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations and undertakings of each Qualified ECP Guarantor under this
Section 27 shall remain in full force and effect until the Guaranteed Obligations have been paid and performed in full. Each Qualified ECP Guarantor intends this Section 27 to constitute, and this Section 27 shall be deemed to
constitute, a guarantee of the obligations of, and a “keepwell, support, or other agreement” for the benefit of, each Specified Loan Party for all purposes of the Commodity Exchange Act. A “Qualified ECP Guarantor” shall
mean, in respect of any Swap Obligation, each Credit Party that has total assets exceeding $10,000,000 at the time the Guaranty or grant of the relevant security interest becomes effective with respect to such Swap Obligation or such other person as
constitutes an “eligible contract participant” under the Commodity Exchange Act or any regulations promulgated thereunder and can cause another person to qualify as an “eligible contract participant” at such time by entering into
a keepwell under Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

 IN WITNESS WHEREOF, each Guarantor has caused this Guaranty to be executed
and delivered as of the date first above written.

 JOINDER AGREEMENT 

Reference is made to (i) the First Lien Term Loan Credit Agreement, dated as of October 20, 2016, among Shay Intermediate Holding II

together with the Lead Borrower, the “Borrowers”), the lenders party thereto from time to time (the “Lenders”) and Bank of America, N.A., as administrative agent (together with any successor administrative agent,
the “Administrative Agent”) (as amended, modified, restated and/or supplemented from time to time, the “Credit Agreement”) and (ii) the First Lien Subsidiaries Guaranty, dated as of October 20, 2016 (as
amended, restated, amended and restated, modified or supplemented from time to time, the “Subsidiaries Guaranty”), made by each of the guarantors party thereto in favor of the Administrative Agent. Capitalized terms used herein and
not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement or in the Subsidiaries Guaranty, as applicable. 

W I T N E S S E T H: 

WHEREAS, the Subsidiary Guarantors have entered into the Subsidiaries Guaranty in order to induce the Lenders to make the Term Loans to the
Borrowers and the Other Creditors to enter into Designated Interest Rate Protection Agreements and Designated Treasury Services Agreements with the Lead Borrower and/or one or more of its Restricted Subsidiaries; 

WHEREAS, pursuant to Section 9.12 of the Credit Agreement and Section 26 of the Subsidiaries Guaranty, each person that is or
becomes a Wholly-Owned Domestic Subsidiary of a Restricted Subsidiary after the Closing Date (other than an Excluded Subsidiary) is required to become a Subsidiary Guarantor under the Credit Agreement. The undersigned Subsidiary (the “New
Guarantor”) is executing this joinder agreement (this “Joinder Agreement”) to the Subsidiaries Guaranty as required by the Credit Agreement; 

NOW, THEREFORE, the Administrative Agent and the New Guarantor hereby agree as follows: 

1.    Guarantee. In accordance with Section 26 of the Subsidiaries Guaranty, the New Guarantor by its signature

2.    Representations and Warranties. The New Guarantor hereby (a) agrees to all the terms and provisions of
the Subsidiaries Guaranty applicable to it as a Subsidiary Guarantor, respectively, thereunder and (b) represents and warrants that the representations and warranties made by it as a Subsidiary Guarantor thereunder are true and correct in all

Subsidiary Guarantor in the Credit Agreement and to a Guarantor in the Subsidiary Guaranty shall be deemed to include the New Guarantor. 

Exhibit A-1 

 3.    Severability. Any provision of this Joinder Agreement which
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 provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 

4.    Counterparts. This Joinder Agreement may be executed in counterparts, each of which shall constitute an
original. Delivery of an executed signature page to this Joinder Agreement by facsimile transmission shall be as effective as delivery of a manually executed counterpart of this Joinder Agreement. 

5.    No Waiver. Except as expressly supplemented hereby, the Subsidiaries Guaranty shall remain in full force and
effect. 
 6.    Notices. All notices, requests and demands to or upon the New Guarantor, any Agent or any Lender

 FIRST LIEN SECURITY AGREEMENT 

FIRST LIEN SECURITY AGREEMENT, dated as of October 20, 2016, made by each of the undersigned grantors (each, a “Grantor”
and, together with any other entity that becomes a grantor hereunder pursuant to Section 10.12 hereof, the “Grantors”) in favor of Bank of America, N.A., as Collateral Agent (together with any successor Collateral Agent, the
“Collateral Agent”), for the benefit of the Secured Creditors (as defined below). Certain capitalized terms as used herein are defined in Article IX hereof. Except as otherwise defined herein, all capitalized terms used herein and
defined in the Credit Agreement (as defined below) shall be used herein as therein defined. 
 W I T N E S S E T H: 

WHEREAS, Shay Intermediate Holding II Corporation, a Delaware corporation (“Holdings”), PAE Holding Corporation, a Delaware
corporation (the “Lead Borrower”), the Subsidiary Borrowers party thereto (and together with the Lead Borrower, the “Borrowers”), the lenders party thereto from time to time (the “Lenders”) and Bank
of America, N.A., as administrative agent (together with any successor administrative agent, the “Administrative Agent”), have entered into a First Lien Term Loan Credit Agreement dated as of even date herewith (as amended,
modified, restated and/or supplemented from time to time, the “Credit Agreement”), providing for the making of Term Loans to the Borrower, as contemplated therein (the Lenders, the Administrative Agent, the Collateral Agent and each
other Agent are herein called the “Lender Creditors”); 
 WHEREAS, the Lead Borrower and/or one or more of its Restricted
Subsidiaries may at any time and from time to time enter into one or more Designated Interest Rate Protection Agreements and Designated Treasury Services Agreements with Guaranteed Creditors (the Administrative Agent, each Lender Creditor and each
Guaranteed Creditor, together with their permitted successors and assigns, if any, collectively, the “Secured Creditors”); 

WHEREAS, pursuant to the Credit Agreement Party Guaranty, each of Holdings and each Borrower has guaranteed to the Secured Creditors the
payment when due of all of its Relevant Guaranteed Obligations; 
 WHEREAS, pursuant to the Subsidiaries Guaranty, each Subsidiary Guarantor
has jointly and severally guaranteed to the Secured Creditors the payment when due of all of its Relevant Guaranteed Obligations; 

WHEREAS, it is a condition precedent to the making of Term Loans to the Borrowers under the Credit Agreement and to the Guaranteed Creditors
entering into Interest Rate Protection Agreements, Other Hedging Agreements and Treasury Services Agreements that each Grantor shall have executed and delivered to the Collateral Agent this Agreement; and 

WHEREAS, each Grantor will obtain benefits from the incurrence of Term Loans by the Borrowers under the Credit Agreement and the entering into
by the Lead Borrower and/or one or more of its Restricted Subsidiaries of Interest Rate Protection Agreements, Other Hedging Agreements and Treasury Services Agreements and, accordingly, desires to execute this Agreement in order to satisfy the
condition described in the preceding paragraph and to induce the Lenders to make Term Loans to the Lead Borrower and the Guaranteed Creditors to enter into Interest Rate Protection Agreements, Other Hedging Agreements and Treasury Services Agreement
with the Borrower and/or one or more of its Restricted Subsidiaries; 

  
 1 

 NOW, THEREFORE, in consideration of the benefits accruing to each Grantor, the receipt and

ARTICLE II 
 GENERAL
REPRESENTATIONS, WARRANTIES AND COVENANTS 
 Each Grantor represents and warrants as of the date hereof, and, until the Termination Date,
covenants, which representations, warranties and covenants shall survive execution and delivery of this Agreement, as follows: 
 2.1
Necessary Perfection Action. The security interest granted to the Collateral Agent pursuant to this Agreement in and to the Collateral for the benefit of the Collateral Agent and the Secured Creditors creates a valid security interest and
Lien upon such Grantor’s right, title and interest in and to the Collateral. Except to the extent perfection is not required hereunder, such security interest will be duly perfected (A) upon the filing of the UCC financing statements
delivered to the Collateral Agent for filing in the appropriate jurisdictions set forth on Schedule 6 of the Perfection Certificate, (B) in Deposit Accounts upon the obtaining and maintenance of “control” (as described in the UCC as
in effect on the date hereof in the State of New York) by the Collateral Agent (it being understood that, notwithstanding anything to the contrary contained in this Agreement or any other Credit Document, no “control” over any Excluded
Deposit Accounts shall be required), (C) upon the recordation of a short form security agreement with respect to the U.S. registered intellectual property disclosed in Schedules 11(a) and 11(b) of the Perfection Certificate in the PTO or the United
States Copyright Office, as the case may be; provided, however, that additional filings may be necessary to perfect the Collateral Agent’s security interest in, and Lien on, any Patents, Marks, Copyrights, Domain Names, Trade
Secret Rights and other intellectual property acquired after the date hereof, and (D) upon the receipt by the Collateral Agent of all Instruments, Chattel Paper and certificated pledged Equity Interests that constitute “securities”
governed by Article 8 of the UCC, in each case constituting Collateral in suitable form for transfer by delivery or accompanied by instruments of transfer or assignment duly executed in blank. 

Upon the taking of the actions under this Section 2.1, such security interest will be superior to and prior to all other Liens of all
other Persons (other than Permitted Liens), and enforceable as such as against all other Persons (except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws generally affecting creditors’ rights and by equitable principles (regardless of whether enforcement is sought in equity or at law)) other than Ordinary Course Transferees. 

 

  
 5 

 2.2 No Liens. Such Grantor is, and as to all Collateral acquired by it from time to
time after the date hereof such Grantor will be, the owner of, or otherwise have the right to use, all Collateral free from any Lien of any Person (other than Permitted Liens), and such Grantor shall, at its own expense, take all commercially
reasonable actions necessary to defend the Collateral against all claims and demands of all Persons at any time claiming the same or any interest therein materially adverse to the Collateral Agent (other than Permitted Liens). 

2.3 Other Financing Statements. As of the date hereof, no Grantor has filed, nor authorized the filing by any third party of any
financing statement (or similar statement or instrument of registration under the law of any jurisdiction) covering or purporting to cover any interest of any kind in the Collateral (other than financing statements or other statements or instruments
of registration under the law of any jurisdiction filed in respect of Permitted Liens), and so long as the Termination Date has not occurred, such Grantor will not authorize to be filed in any public office any financing statement (or similar
statement or instrument of registration under the law of any jurisdiction) relating to the Collateral, except financing statements filed or to be filed in respect of and covering the security interests granted hereby by such Grantor or in connection
with Permitted Liens. 
 2.4 Chief Executive Office, Record Locations. The chief executive office of such Grantor is, on the date of
this Agreement, located at the address indicated on Schedule 2(a) of the Perfection Certificate for such Grantor. During the period of the four calendar months preceding the date of this Agreement, the chief executive office of such Grantor has not
been located at any address other than that indicated on Schedule 2(a) of the Perfection Certificate in accordance with the immediately preceding sentence, in each case unless each such other address is also indicated on Schedule 2(a) of the
Perfection Certificate for such Grantor. 
 2.5 Location of Goods, Inventory and Equipment. All Goods, Inventory and Equipment (having
a fair market value in excess of $3,000,000 with respect to Collateral comprising Goods, Inventory and Equipment only) held on the date hereof, or held at any time during the four calendar months prior to the date hereof, by each Grantor, other than

name appears in its public organic record, the type of organization of such Grantor, whether or not such Grantor is a Registered Organization, the jurisdiction of organization of such Grantor, such Grantor’s Location, the organizational

 2.9 As-Extracted
Collateral; Timber-to-be-Cut. On the date hereof, such Grantor does not own, or expect to acquire, any material property
which constitutes, or would constitute, As-Extracted Collateral or Timber-to-be-Cut.

 ARTICLE III 

SPECIAL PROVISIONS CONCERNING ACCOUNTS; CONTRACT RIGHTS;

than 90% of the aggregate revenue of the Grantors on a consolidated basis for the trailing twelve-month period ending on the last day of the period for which internally generated financial statements of the Lead Borrower and its Subsidiaries are
available, such additional contracts with Applicable Governmental Authorities that would result in the Receivables under contracts on such list representing no less than 90% of the aggregate revenue of the Grantors on a consolidated basis for such
trailing twelve-month period, and promptly execute whatever instruments and documents are required by the Administrative Agent in order that such Receivables shall be assigned to the Administrative Agent and that proper notice of such assignment
shall be given under the Federal Assignment of Claims Act (or any successor statute) or any other applicable Requirement of Law; provided that, if any contract with any Applicable Governmental Authority requires consent by or on behalf of
such Applicable Governmental Authority in order for any such Receivable to be assigned pursuant to the applicable Requirements of Law, such Grantor shall only be required to exercise commercially reasonably efforts to obtain such consent (and if
such consent cannot be obtained, no Grantor shall be in breach hereof). As used in this Section 3.1, the term “Applicable Governmental Authority” shall mean the United States of America, or any state

(including, without limitation, all documents evidencing the Accounts and all Contract Rights) and such books and records to the Collateral Agent or to its representatives (copies of which evidence and books and records may be retained by such
Grantor). Subject to the terms of the ABL Intercreditor Agreement, upon the occurrence and during the continuance of an Event of Default and if the Collateral Agent so requests, such Grantor shall legend, in form and manner reasonably satisfactory
to the Collateral Agent, the Accounts and the Contracts, as well as books, records and documents (if any) of such Grantor evidencing or pertaining to such Accounts and Contracts with an appropriate reference to the fact that such Accounts and
Contracts have been assigned to the Collateral Agent and that the Collateral Agent has a security interest therein.

compromise the amount of payment thereof, in the same manner and to the same extent as such Grantor; provided that, (x) any failure by the Collateral Agent to give or any delay in giving such notice to the relevant Grantor shall not

Agent shall deliver a copy of each notice referred to in the preceding clause (y) to the relevant Grantor, provided that (x) the failure by the Collateral Agent to so notify such Grantor shall not affect the effectiveness of such
notice or the other rights of the Collateral Agent created by this Section 3.3 and (y) no such notice shall be required if an Event of Default of the type described in Section 11.05 of the Credit Agreement has occurred and is
continuing.

adjustment with respect thereto, or extend or renew the same, or compromise or settle any material dispute, claim, suit or legal proceeding relating thereto, or sell any Account, or interest therein, without the prior written consent of the

so collected to the outstanding balance of such Account or under such Contract. Except as otherwise directed by the Collateral Agent after the occurrence and during the continuation of an Event of Default or otherwise required pursuant to the Credit

reasonable attorneys’ fees) of collection, whether incurred by a Grantor or the Collateral Agent, shall be borne by the relevant Grantor (in the case of any such costs and expenses incurred by the Collateral Agent, in accordance with the terms
and provisions of Section 13.01 of the Credit Agreement).

Collateral Agent thereof, and upon request by the Collateral Agent (subject to the ABL Intercreditor Agreement), promptly deliver such Instrument to the Collateral Agent appropriately endorsed in blank or to the order of the Collateral Agent,
provided that, so long as no Event of Default shall have occurred and be continuing, such Grantor may retain for collection in the ordinary course of 

  
 9

giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by them or as to the sufficiency of any performance by any party under any Account (or any agreement giving rise thereto), to
present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to them or to which they may be entitled at any time or times.

Grantor’s rights in and to any Mark or Domain Name in any manner that would reasonably be expected to have a Material Adverse Effect, or with respect to any party claiming that such Grantor’s use of any Mark or Domain Name material to such
Grantor’s business violates in any material respect any intellectual property right of that party. Each Grantor further agrees to prosecute diligently in accordance with its reasonable business judgment, any Person infringing any Mark or Domain
Name owned by it in any manner that would reasonably be expected to have a Material Adverse Effect.

and to take all such other actions as are reasonably necessary to preserve such Marks as trademarks or service marks under the laws of the United States (other than any such material Marks that are no longer material or are deemed by such Grantor in
its reasonable business judgment to no longer be necessary in the conduct of Grantor’s business).

exhaustion of all administrative and judicial remedies without prior written consent of the Collateral Agent, not to be unreasonably withheld (other than with respect to registrations and applications deemed by such Grantor in its reasonable
business judgment to be no longer prudent to pursue or as otherwise permitted by the Credit Agreement).

 4.6 Future Registered Marks and Domain Names. If any Mark registration is issued
hereafter prior to the Termination Date to any Grantor as a result of any application now or hereafter prior to the Termination Date pending before the PTO or any Domain Name is registered by Grantor prior to the Termination Date, on or prior to the
next Quarterly Update Date, such Grantor shall deliver to the Collateral Agent an updated Schedule 11(a) of the Perfection Certificate, and, if requested by the Collateral Agent, a grant of a security interest in such Mark and/or Domain Name, to the
Collateral Agent and at the expense of such Grantor, confirming the grant of a security interest in such Mark and/or Domain Name to the Collateral Agent hereunder, the form of such security to be substantially in the form of Exhibit C hereto or in
such other form as may be reasonably satisfactory to the Collateral Agent.

in and to each of the Marks and Domain Names, together with all trademark rights and rights of protection to the same, vested in the Collateral Agent for the benefit of the Secured Creditors, in which event such right, title and interest shall
immediately vest, in the Collateral Agent for the benefit of the Secured Creditors, and the Collateral Agent shall be entitled to exercise the power of attorney referred to in Section 4.1 hereof to execute, cause to be acknowledged and
notarized and record said absolute assignment with the applicable agency or registrar; (ii) take and use or sell the Marks or Domain Names and the goodwill of such Grantor’s business symbolized by the Marks or Domain Names and the right to
carry on the business and use the assets of such Grantor in connection with which the Marks or Domain Names have been used (provided that any license shall be subject to reasonable quality control); and (iii) direct such Grantor to
refrain, in which event such Grantor shall refrain, from using the Marks or Domain Names in any manner whatsoever, directly or indirectly, and such Grantor shall execute such further documents that the Collateral Agent may reasonably request to
further confirm this and to transfer ownership of the Marks or Domain Names owned by it and registrations and any pending trademark applications in the PTO or applicable Domain Name registrar therefor to the Collateral Agent. Solely for the purpose
of enabling the Collateral Agent to exercise rights and remedies under this Section 4.7 and at such time as the Collateral Agent shall be lawfully entitled, and permitted under the Credit Agreement, to exercise such rights and remedies, each
Grantor hereby grants to the Collateral Agent, to the extent it has the right to do so, an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to such Grantor), subject, in the case of Trademarks, to
sufficient rights to quality control and inspection in favor of such Grantor to avoid the risk of invalidation of said Trademarks, to use, operate under, license, or sublicense any Marks and Domain Names now owned or hereafter acquired by such
Grantor to the extent constituting Collateral hereunder.

or would reasonably be 

  
 13 

 expected to have, a Material Adverse Effect. Each Grantor hereby grants to the Collateral Agent a power of
attorney to sign, solely upon the occurrence and during the continuance of any Event of Default, any document which may be required by the PTO or the United States Copyright Office in order to effect an assignment of all right, title and interest in
each Patent listed in Schedule 11(a) of the Perfection Certificate or Copyright listed in Schedule 11(b) of the Perfection Certificate, or any other issued or applied-for United States patent or registered or applied-for United States copyright hereinafter owned by such Grantor, and to record the same. 
 5.2
Assignments. Except as otherwise permitted by the Secured Debt Agreements, each Grantor hereby agrees not to assign or otherwise transfer to any third party all or substantially all rights in any material Patent or material Copyright absent
prior written approval of the Collateral Agent. 
 5.3 Infringements. Each Grantor agrees, promptly upon learning thereof, to furnish
the Collateral Agent in writing with all pertinent information available to such Grantor with respect to any infringement, contributing infringement or active inducement to infringe or other violation of such Grantor’s rights in any Patent or
Copyright or to any claim that the practice of any Patent or use of any Copyright by such Grantor violates any intellectual property right of a third party, or with respect to any misappropriation of any Trade Secret Right by such Grantor or any
claim that practice of any Trade Secret Right by such Grantor violates any intellectual property right of a third party, in each case, in any manner which, either individually or in the aggregate, has, or would reasonably be expected to have, a
Material Adverse Effect. Each Grantor further agrees to diligently prosecute, in accordance with such Grantor’s reasonable business judgment, any Person infringing any Patent owned by it or Copyright or any Person misappropriating any Trade
Secret Right, in each case to the extent that such infringement or misappropriation, either individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect. 

5.4 Maintenance of Patents or Copyrights. At its own expense, each Grantor shall make timely payment of all post-issuance fees required
to maintain in force its rights under each issued Patent or registered Copyright, absent prior written consent of the Collateral Agent (other than any such Patents or Copyrights that are no longer material or are deemed by such Grantor in its
reasonable business judgment to no longer be necessary in the conduct of Grantor’s business). 
 5.5 Prosecution of Patent or
Copyright Applications. At its own expense, each Grantor shall diligently prosecute all material applications for (i) United States Patents listed in Schedule 11(a) of the Perfection Certificate and (ii) Copyrights listed on Schedule

Grantor in its reasonable business judgment to no longer be necessary in the conduct of Grantor’s business), absent written consent of the Collateral Agent not to be unreasonably withheld.

a registered Copyright, or of filing of an application for a United States Patent or Copyright, the relevant Grantor shall deliver to the Collateral Agent an updated Schedule 11 of the Perfection Certificate on or prior to the next Quarterly Update

such grant of a security interest to be substantially in the form of Exhibit A or B hereto, as appropriate, or in such other form as may be reasonably satisfactory to the Collateral Agent.

terms of the ABL Intercreditor Agreement, the Collateral Agent may, by written notice to the relevant Grantor, take any or all of the following actions: (i) declare the entire right, title, and interest of such Grantor in each of the Patents,
Copyrights and Trade Secret Rights vested in the Collateral Agent for the benefit of the Secured Creditors, in which event such right, title, and interest shall immediately vest in the Collateral Agent for the benefit of the Secured Creditors, and
the Collateral Agent shall be entitled to exercise the power of attorney referred to in Section 5.1 hereof to execute, cause to be acknowledged and notarized and to record said assignment with the applicable agency; (ii) take and practice
or sell the Patents, Copyrights and Trade Secrets, in each case, owned by such Grantor, and exercise any other rights vested in the Patents, Copyrights and Trade Secrets pursuant to Section 5.7(i) above; and (iii) direct such Grantor to

Collateral Agent, to the extent it has the right to do so, an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to such Grantor), to use, operate under, license, or sublicense any Patents, Copyrights and
Trade Secrets now owned or hereafter acquired by such Grantor to the extent constituting Collateral hereunder. 
 ARTICLE VI 

PROVISIONS CONCERNING ALL COLLATERAL 

6.1 Protection of Collateral Agent’s Security. Except as otherwise permitted or not prohibited by the Secured Debt Agreements,
each Grantor will do nothing to impair the rights of the Collateral Agent in the Collateral. Each Grantor or an affiliate on behalf of such Grantor will at all times maintain insurance, at such Grantor’s own expense to the extent and in the
manner provided in the Secured Debt Agreements. If any Event of Default shall have occurred and be continuing, the Collateral Agent shall, at the time any proceeds of such insurance are distributed to the Secured Creditors, apply such proceeds in
accordance with Section 7.4 hereof. Each Grantor assumes all liability and responsibility in connection with the Collateral acquired by it and the liability of such Grantor to pay the Obligations shall in no way be affected or diminished by
reason of the fact that such Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever unavailable to such Grantor. 

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

6.3 Additional Information. Each Grantor will, at its own expense, from time to time upon the reasonable request of the Collateral
Agent, promptly furnish to the Collateral Agent such information with respect to the Collateral (including the identity of the Collateral or such components thereof as may have been reasonably requested by the Collateral Agent, the value and
location of such Collateral, etc.) as may be requested by the Collateral Agent. 
 6.4 Further Actions. To the extent otherwise
required by this Agreement or the other Credit Documents, each Grantor will, at its own expense and upon the reasonable request of the Collateral Agent, make, execute, endorse, acknowledge, file and/or deliver to the Collateral Agent from time to
time such lists, descriptions and designations of its Collateral, warehouse receipts, receipts in the nature of 

  
 15 

 warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory
assignments, conveyances, financing statements, transfer endorsements, certificates, reports and other assurances or instruments and take such further steps relating to the Collateral and other property or rights covered by the security interest
hereby granted, which the Collateral Agent deems reasonably appropriate or advisable to perfect, preserve or protect its security interest in the Collateral at least to the extent described in Section 2.1. 

6.5 Financing Statements. Each Grantor agrees to deliver to the Collateral Agent such financing statements, in form reasonably
acceptable to the Collateral Agent, as the Collateral Agent may from time to time reasonably request to establish and maintain a valid, enforceable, perfected security interest in the Collateral as provided herein and for the purpose of obtaining
and preserving the full benefits of the other rights and security contemplated hereby at least to the extent described in Section 2.1. Each Grantor will pay any applicable filing fees, recordation taxes and related expenses relating to its
Collateral. Each Grantor hereby authorizes the Collateral Agent to file any such financing statements (and such authorization includes describing the Collateral as “all assets and all personal property whether now owned or hereafter
acquired” of such Grantor or words of similar effect). 
 ARTICLE VII 

REMEDIES UPON OCCURRENCE OF AN EVENT OF DEFAULT 

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

(i) personally, or by agents or attorneys, immediately take possession of the Collateral or any part thereof, from such Grantor or any other
Person who then has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon such Grantor’s premises where any of the Collateral is located and remove the same and use in connection with such
removal any and all services, supplies, aids and other facilities of such Grantor, in each case without breach of the peace; 
 (ii) instruct
the obligor or obligors on any agreement, instrument or other obligation (including, without limitation, the Accounts and the Contracts) constituting the Collateral to make any payment required by the terms of such agreement, instrument or other
obligation directly to the Collateral Agent and may exercise any and all remedies of such Grantor in respect of such Collateral; 
 (iii)
instruct all banks which have entered into a control agreement with the Collateral Agent to transfer all monies, securities and instruments held by such depositary bank to an Account designated by the Collateral Agent; it being understood and agreed
that unless an Event of Default has occurred and is continuing, the Collateral Agent shall not deliver to such banks a “notice of exclusive control” under, and as defined in, the respective “control agreement” relating thereto;

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

  
 16 

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

(x) forthwith cause the same to be moved to the place or places so designated by the Collateral Agent and there delivered to
the Collateral Agent; 
 (y) store and keep any Collateral so delivered to the Collateral Agent at such place or places
pending further action by the Collateral Agent as provided in Section 7.2 hereof; and 
 (z) while the Collateral shall
be so stored and kept, provide such security and maintenance services as shall be reasonably necessary to protect the same and to preserve and maintain it in good condition; 

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

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

 (viii) take any other action as specified in clauses (a)(1) through (a)(5), inclusive, of
Section 9-607 of the UCC; 
 it being understood that each Grantor’s obligation so to deliver the
Collateral is of the essence of this Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Collateral Agent shall be entitled to a decree requiring specific performance by such Grantor of said obligation. By
accepting the benefits of this Agreement and each other Security Document, the Secured Creditors expressly acknowledge and agree that this Agreement and each other Security Document may be enforced only by the action of the Collateral Agent and that
no Secured Creditor shall have any right individually to seek to enforce or to enforce this Agreement or to realize upon the security to be granted hereby, it being understood and agreed that such rights and remedies may be exercised by the
Collateral Agent. 
 7.2 Remedies; Disposition of the Collateral. To the extent permitted by applicable law, if any Event of Default
shall have occurred and be continuing, then any Collateral repossessed by the Collateral Agent under or pursuant to Section 7.1 hereof and any other Collateral whether or not so repossessed by the Collateral Agent, may be sold, assigned, leased
or otherwise disposed of under one or more contracts or as an entirety, and without the necessity of gathering at the place of sale the property to be sold, and in general in such manner, at such time or times, at such place or places and on such
terms as the Collateral Agent may, in compliance with any mandatory requirements of applicable law, determine to be commercially reasonable. Any of the Collateral may be sold, leased or otherwise disposed of, in the condition in which the same
existed when taken by the Collateral Agent or after any overhaul or repair at the expense of the relevant Grantor which the Collateral Agent shall determine to be commercially reasonable. Any such sale, lease or other disposition may be effected by
means of a public disposition or private disposition, effected in accordance with the applicable requirements (in each case if and to the extent applicable) of Sections 9-610 through 9-613 of the UCC and/or such other mandatory requirements 

  
 17 

 of applicable law as may apply to the respective disposition. The Collateral Agent may, without notice or
publication, adjourn any public or private disposition or cause the same to be adjourned from time to time by announcement at the time and place fixed for the disposition, and such disposition may be made at any time or place to which the
disposition may be so adjourned. To the extent permitted by any such requirement of law, the Collateral Agent may bid for and become the purchaser (and may pay all or any portion of the purchase price by crediting Obligations against the purchase
price) of the Collateral or any item thereof, offered for disposition in accordance with this Section 7.2 without accountability to the relevant Grantor. Each Grantor agrees to do or cause to be done all such other acts and things as may be
reasonably necessary to make such disposition or dispositions of all or any portion of the Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all
courts, arbitrators or governmental instrumentalities, having jurisdiction over any such sale or sales, all at such Grantor’s expense. 

7.3 Waiver of Claims. Except as otherwise provided in this Agreement, EACH GRANTOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENT’S TAKING POSSESSION OR THE COLLATERAL AGENT’S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY
PREJUDGMENT REMEDY OR REMEDIES, and each Grantor hereby further waives, to the extent permitted by law: 
 (a) all damages occasioned by such
taking of possession or any such disposition except any damages which are the direct result of the Collateral Agent’s gross negligence, bad faith or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision); 
 (b) all other requirements as to the time, place and terms of sale or other
requirements with respect to the enforcement of the Collateral Agent’s rights hereunder; and 
 (c) all rights of redemption,
appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable law in order to prevent or delay the enforcement of this Agreement or the absolute sale of the Collateral or any portion thereof, and each Grantor,
for itself and all who may claim under it, insofar as it or they now or hereafter lawfully may, hereby waives the benefit of all such laws. 

Any sale of, or the grant of options to purchase, or any other realization upon, any Collateral shall operate to divest all right, title,
interest, claim and demand, either at law or in equity, of the relevant Grantor therein and thereto, and shall be a perpetual bar both at law and in equity against such Grantor and against any and all Persons claiming or attempting to claim the
Collateral so sold, optioned or realized upon, or any part thereof, from, through and under such Grantor. 
 7.4 Application of
Proceeds. 
 (a) Subject to the terms of the ABL Intercreditor Agreement, all moneys collected by the Collateral Agent (or, to the extent
the Pledge Agreement or any other Security Document requires proceeds of collateral under such other Security Document to be applied in accordance with the provisions of this Agreement, the Pledgee under, and as defined in, the Pledge Agreement, or
collateral agent under such other Security Document) upon any sale or other disposition of the Collateral (or the collateral under the relevant Security Document), together with all other moneys received by the Collateral Agent hereunder (or under
the relevant Security Document), in each case, as a result of the exercise of remedies by the Collateral Agent after the occurrence and during the continuance of an Event of Default, shall be applied as follows: 

  
 18 

 (i) first, to the payment of all amounts owing the Collateral Agent of the type
described in clauses (iii), (iv) and (v) of the definition of “Obligations”; 
 (ii) second, to the extent proceeds
remain after the application pursuant to the preceding clause (i), to the payment of all amounts owing to any Agent of the type described in clauses (v) and (vi) of the definition of “Obligations”; 

(iii) third, to the extent proceeds remain after the application pursuant to the preceding clauses (i) and (ii), an amount equal,
and payable ratably, to all unpaid principal of, premium, if any, fees and interest (including interest accruing during the pendency of any bankruptcy, insolvency, receivership or similar proceeding, regardless of whether allowed or allowable in
such proceeding) on, all Term Loans, and all amounts due under each Designated Interest Rate Protection Agreement or Designated Treasury Services Agreement with a Guaranteed Creditor; 

(iv) fourth, to the extent proceeds remain after the application pursuant to preceding clauses (i) through (iii), inclusive,
ratably to any then remaining unpaid Obligations; and 
 (v) fifth, to the extent proceeds remain after the application pursuant to
the preceding clauses (i) through (iv), inclusive, and following the termination of this Agreement pursuant to Section 10.8(a) hereof, to the relevant Grantor or to whomever may be lawfully entitled to receive such surplus. 

(b) [Reserved]. 
 (c) [Reserved].

 (d) All payments required to be made hereunder shall be made (x) if to the Lender Creditors, to the Administrative Agent for the
account of the Lender Creditors and (y) if to the Guaranteed Creditors, to the trustee, paying agent or other similar representative (each, a “Representative”) for the Guaranteed Creditors or, in the absence of such a
Representative, directly to the Guaranteed Creditors. 
 (e) For purposes of applying payments received in accordance with this
Section 7.4, the Collateral Agent shall be entitled to rely upon (i) the Administrative Agent and (ii) the Representative or, in the absence of such a Representative, upon the Guaranteed Creditors for a determination (which the
Administrative Agent, each Representative and the Guaranteed Creditors agree (or shall agree) to provide upon request of the Collateral Agent) of the outstanding Primary Obligations and Secondary Obligations owed to the Lender Creditors or the
Guaranteed Creditors, as the case may be. Unless it has received written notice from a Lender Creditor or a Guaranteed Creditor to the contrary, the Administrative Agent and each Representative, in furnishing information pursuant to the preceding
sentence, and the Collateral Agent, in acting hereunder, shall be entitled to assume that no Secondary Obligations are outstanding. Unless it has written notice from a Guaranteed Creditor to the contrary, the Collateral Agent, in acting hereunder,
shall be entitled to assume that no Designated Interest Rate Protection Agreements or Designated or Treasury Services Agreements that constitute Obligations are in existence. 

  
 19 

 (f) It is understood that the Grantors shall remain jointly and severally liable to the
extent of any deficiency between the amount of the proceeds of the Collateral and the aggregate amount of the Obligations. 
 7.5 Remedies
Cumulative. Each and every right, power and remedy hereby specifically given to the Collateral Agent shall be in addition to every other right, power and remedy specifically given to the Collateral Agent under this Agreement, the other Secured
Debt Agreements or now or hereafter existing at law, in equity or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in
such order as may be deemed expedient by the Collateral Agent. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or
others. No delay or omission of the Collateral Agent in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any
Default or Event of Default or an acquiescence thereof. No notice to or demand on any Grantor in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the
Collateral Agent to any other or further action in any circumstances without notice or demand. In the event that the Collateral Agent shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit
the Collateral Agent may recover reasonable invoiced out-of-pocket expenses, including reasonable attorneys’ fees, and the amounts thereof shall be included in such
judgment, in each case, in accordance with the terms and provisions of Section 13.01 of the Credit Agreement. 
 7.6 Discontinuance
of Proceedings. In case the Collateral Agent shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned
for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case the relevant Grantor, the Collateral Agent and each holder of any of the Obligations shall be restored to their former positions and rights
hereunder with respect to the Collateral subject to the security interest created under this Agreement, and all rights, remedies and powers of the Collateral Agent shall continue as if no such proceeding had been instituted. 

ARTICLE VIII 
 INDEMNITY 

8.1 Indemnity. The terms of Section 13.01 of the Credit Agreement are incorporated herein by reference, mutatis mutandis,
and the parties hereto agree to such terms. 
 8.2 Indemnity Obligations Secured by Collateral; Survival. Any amounts paid by any
Indemnified Person as to which such Indemnified Person has the right to reimbursement shall constitute Obligations secured by the Collateral. The indemnity obligations of each Grantor contained in the Credit Agreement shall continue in full force
and effect notwithstanding the full payment of all of the other Obligations and notwithstanding the full payment of all the Notes issued, and Term Loans made, under the Credit Agreement, the termination of all Designated Interest Rate Protection
Agreements and Designated Treasury Services Agreement entered into with the Guaranteed Creditors and the payment of all other Obligations and notwithstanding the discharge thereof and the occurrence of the Termination Date.

 10.7 Grantor’s Duties. It is expressly agreed, anything herein contained to the
contrary notwithstanding, that each Grantor shall remain liable to perform all of the obligations, if any, assumed by it with respect to the Collateral and the Collateral Agent shall not have any obligations or liabilities with respect to any
Collateral by reason of or arising out of this Agreement, nor shall the Collateral Agent be required or obligated in any manner to perform or fulfill any of the obligations of any Grantor under or with respect to any Collateral. 

10.8 Termination; Release. 

(a) On the Termination Date, this Agreement shall terminate, all without delivery of any instrument or performance of any act by any party, and
all rights to the Collateral shall revert to the Grantors (provided that all indemnities set forth herein including, without limitation in Section 8.1 hereof, shall survive such termination) and the Collateral Agent, at the request and expense
of the respective Grantor, will promptly execute and deliver to such Grantor a proper instrument or instruments (including, without limitation, UCC termination statements on form UCC-3) acknowledging the
satisfaction and termination of this Agreement, and will duly assign, transfer and deliver to such Grantor (without recourse and without any representation or warranty) such of the Collateral as may be in the possession of the Collateral Agent and

(b) In the event that any part of the Collateral is sold or otherwise disposed of (to a Person other than a Credit Party) in connection with a
sale or disposition permitted by Section 10.02 of the Credit Agreement or is otherwise released at the direction of the Required Lenders (or all the Lenders if required by Section 13.12 of the Credit Agreement) and the proceeds of such
sale or disposition (or from such release) are applied in accordance with the terms of the Credit Agreement, to the extent required to be so applied, the security interest created hereby will be automatically released and the Collateral Agent will
execute and deliver such documentation, including termination or partial release statements and the like in connection therewith at the request and expense of such Grantor and assign, transfer and deliver to such Grantor (without recourse and
without any representation or warranty) such of the Collateral as is then being (or has been) so sold or otherwise disposed of, or released, and as may be in the possession of the Collateral Agent and has not theretofore been released pursuant to
this Agreement. Furthermore, upon the release of any Subsidiary Guarantor from the Subsidiaries Guaranty in accordance with the provisions thereof, such Grantor (and the Collateral at such time assigned by the respective Grantor pursuant hereto)
shall be released from this Agreement. 
 (c) At any time that a Grantor desires that the Collateral Agent take any action to acknowledge or
give effect to any release of Collateral pursuant to the foregoing Section 10.8(b), such Grantor shall deliver to the Collateral Agent (and the relevant sub-agent, if any, designated hereunder) a
certificate signed by a Responsible Officer of such Grantor stating that the release of the respective Collateral is permitted pursuant to such Section 10.8(b). At any time that either any Borrower or the respective Grantor desires that, in
connection with a Subsidiary of the Lead Borrower which has been released from the Subsidiaries Guaranty, the Collateral Agent take any action in connection with the release of such Subsidiary hereunder as provided in the last sentence of
Section 10.8(b), it shall deliver to the Collateral Agent a certificate signed by a Responsible Officer of the Lead Borrower and the respective Grantor stating that the release of the respective Grantor (and its Collateral) is permitted
pursuant to such Section 10.8(b). 

  
 29 

 (d) The Collateral Agent shall have no liability whatsoever to any other Secured Creditor as
the result of any release of Collateral by it in accordance with (or which the Collateral Agent in the absence of gross negligence and willful misconduct believes to be in accordance with) this Section 10.8. 

10.9 Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall constitute an original, but all of which, when taken together, shall constitute one and the same instrument. A set of counterparts executed by all the parties hereto shall be lodged
with the Lead Borrower and the Collateral Agent. Delivery of an executed signature page to this Agreement by facsimile, PDF or other electronic transmission shall be as effective as delivery of an original executed counterpart of this Agreement.

 10.10 Severability. Any provision of this Agreement which 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 provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction. 
 10.11 The Collateral Agent and the other Secured Creditors. The Collateral Agent shall
hold in accordance with this Agreement all items of the Collateral at any time received under this Agreement. Until the occurrence and continuation of an Event of Default, the Collateral Agent shall not directly pledge any Collateral in its
possession or control to secure its own debt. It is expressly understood and agreed that the obligations of the Collateral Agent as holder of the Collateral and interests therein and with respect to the disposition thereof, and otherwise under this
Agreement, are only those expressly set forth in this Agreement and in Article 12 of the Credit Agreement. The Collateral Agent shall act hereunder on the terms and conditions set forth herein and in Article 12 of the Credit Agreement. 

10.12 Additional Grantors. It is understood and agreed that any Subsidiary Borrower or Subsidiary Guarantor that desires to become a
Grantor hereunder, or is required to execute a counterpart of this Agreement after the date hereof pursuant to the requirements of the Credit Agreement or any other Credit Document, shall become a Grantor hereunder by executing a counterpart hereof
and delivering same to the Collateral Agent, or by executing and delivering to the Collateral Agent a joinder agreement substantially in the form of Exhibit D attached hereto, (y) delivering a Perfection Certificate and (z) taking
all actions as specified in this Agreement as would have been taken by such Grantor had it been an original party to this Agreement, in each case with all documents required above to be delivered to the Collateral Agent and with all documents and
actions required above to be taken to the reasonable satisfaction of the Collateral Agent. 
 10.13 ABL Intercreditor Agreement. This
Agreement and the other Credit Documents are subject to the terms and conditions set forth in the ABL Intercreditor Agreement in all respects and, in the event of any conflict between the terms of the ABL Intercreditor Agreement and this Agreement,
the terms of ABL Intercreditor Agreement shall govern. Notwithstanding anything herein to the contrary, the Lien and security interest granted to the Collateral Agent pursuant to any Credit Document and the exercise of any right or remedy in respect
of the Collateral by the Collateral Agent (or any Secured Creditor) hereunder or under any other Credit Document are subject to the provisions of the ABL Intercreditor Agreement and in the event of any conflict between the terms of the ABL
Intercreditor Agreement, this Agreement and any other Credit Document, the terms of the ABL Intercreditor Agreement shall govern and control with respect to the exercise of any such right or remedy. Without limiting the generality of the foregoing,
and notwithstanding anything herein to the contrary, no Credit Party shall be required hereunder or under any Credit Document to take any action with respect to the 

  
 30 

 
Collateral that is inconsistent with such Credit Parties’ obligations under the ABL Intercreditor Agreement. Prior to the Discharge of Revolving Credit Obligations, the delivery or granting
of “control” (as defined in the UCC) to the extent only one Person can be granted “control” therein under applicable law of any ABL Collateral (as defined in the ABL Intercreditor Agreement) to the ABL Collateral Agent pursuant
to the terms of the Revolving Credit Collateral Documents (as defined in the ABL Intercreditor Agreement) shall satisfy any such delivery or granting of “control” requirement hereunder or under any other Credit Document with respect to any
ABL Collateral to the extent that such delivery or granting of “control” is consistent with the terms of the ABL Intercreditor Agreement.

W I T N E S S E T H: 
 WHEREAS,
the Grantors have entered into the Security Agreement in order to induce the Lenders to make the Term Loans to the Borrowers and the Guaranteed Creditors to enter into Designated Interest Rate Protection Agreements and Designated Treasury Services

Grantor, to become a Grantor by executing this joinder agreement (“Joinder Agreement”) to the Security Agreement; 
 NOW,
THEREFORE, the Administrative Agent and the New Grantor hereby agree as follows:

 4. Counterparts. This Joinder
Agreement may be executed in counterparts, each of which shall constitute an original. Delivery of an executed signature page to this Joinder Agreement by facsimile, PDF or other electronic transmission shall be as effective as delivery of a
manually executed counterpart of this Joinder Agreement. 
 5. No Waiver. Except as expressly supplemented hereby, the Security
Agreement shall remain in full force and effect. 
 6. Notices. All notices, requests and demands to or upon the New Grantor, any
Agent or any Lender shall be governed by the terms of Section 10.1 of the Security Agreement. 
 7. Governing Law. THIS JOINDER
AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.
