 Reference is
made to (a) the First Lien Credit Agreement dated as of May 10, 2016 (as amended, restated, amended and restated, modified or supplemented from time to time through the date hereof, the “Credit Agreement”), by and among
ATI Holdings Acquisition, Inc., a Delaware corporation (the “Borrower”), Wilco Intermediate Holdings, Inc., a Delaware corporation (“Holdings”), Barclays Bank PLC (“Barclays”) as administrative
agent (in such capacity, including any permitted successor thereto, the “Administrative Agent”) and as collateral agent (in such capacity, including any permitted successor thereto, the “Collateral Agent”) under the

to First Lien Credit Agreement, dated as of the date hereof, among Holdings, the Borrower, the Administrative Agent and the 2016 Incremental Term Loan Lender (as defined therein) party thereto (the “First Amendment”). Capitalized
terms used but not otherwise defined in this Guarantor Consent and Reaffirmation (this “Consent”) are used with the meanings attributed thereto in the Credit Agreement or the First Amendment, as applicable. 

Each Guarantor party hereto hereby consents to the terms and conditions of the First Amendment, including the incurrence by the Borrower of the
2016 Incremental Term Loans contemplated thereby, and agrees that each reference to the Credit Agreement in the Loan Documents shall, on and after the First Amendment Effective Date, be deemed to be a reference to the Credit Agreement as amended by
the First Amendment. 
 Each Guarantor hereby acknowledges and agrees that, after giving effect to the First Amendment, all of its respective
obligations, guarantees, pledges, grants of Liens, liabilities and other agreements or commitments under the Loan Documents to which it is a party, as such obligations, guarantees, pledges, grants of Liens, liabilities and other agreements or
commitments have been amended by the First Amendment, are reaffirmed, and remain in full force and effect. 
 After giving effect to the
First Amendment, each Guarantor reaffirms (i) its guarantee of the Secured Obligations (including, without limitation, the 2016 Incremental Term Loans) and (ii) each Lien granted by it to the Collateral Agent for the benefit of the Secured
Parties under each of the Loan Documents to which it is a party, which Liens shall continue in full force and effect during the term of the Credit Agreement as amended by the First Amendment, and shall continue to secure the Secured Obligations

Each Guarantor hereby acknowledges and agrees that neither the modification of the Credit Agreement effected pursuant to this First Amendment
nor the execution, delivery, performance or effectiveness of this First Amendment or the execution and delivery of this Guarantor Consent and Reaffirmation impairs the validity, effectiveness or priority of the Liens granted pursuant to any Loan

part of the Guarantors to the extent not required by the express terms of the Loan Documents. 
 This Consent is a Loan Document and shall be
governed by, and construed and interpreted in accordance with, the law of the State of New York. 
 This Consent may be executed in
counterparts, and all such counterparts taken together shall be deemed to constitute one and the same instrument. Delivery by facsimile or electronic transmission of an executed counterpart of a signature page to this Consent shall be effective as
