Loan Lender may reasonably agree), the Second Amendment Incremental Commitment shall automatically terminate without any further action by any party hereto and this Second Amendment shall no longer be effective.

Section 2.01(a), Section 4.01(f) and the third sentence of Section 5.11 of the Credit Agreement); 

(d) The 2017 Incremental Term Loan Commitments shall constitute “Term Commitments”; 

(e) The Existing Term Loans and the 2017 Incremental Term Loans shall collectively comprise a single Class of Initial Term

Date together with the 2016 Incremental Term Loans made pursuant to the First Amendment and (c) on and after the Second Amendment Effective Date, the Initial Term Loans made on the Closing Date together with the 2016 Incremental Term Loans made

is required to be drawn pursuant to the applicable Refinancing Amendment or Incremental Facility Amendment, the undrawn amount thereof shall automatically terminate and (vi) the Additional Revolving Credit Commitments of any Class shall
automatically terminate on the Maturity Date specified therefor in the applicable Refinancing Amendment or Incremental Facility Amendment.” 

(d) Section 2.10(a) of the Credit Agreement is hereby amended by amending and restating clause (a) thereof as follows: 

“(a) (i) The Borrower hereby unconditionally promises to repay Initial Term Loans to the Administrative Agent for the account of each Term
Lender on the last Business Day of each March, June, September and December prior to the Initial Term Loan Maturity Date (each such date being referred to as a “Loan Installment Date”), in each case in the amount set forth in the
table below (as such payments may be reduced from time to time as a result of the application of prepayments in accordance with Section 2.11 and repurchases in accordance with Section 9.05(g) or
increased as a result of any increase in the amount of such Initial Term Loans pursuant to Section 2.22(a)) and (ii) on the Initial Term Loan Maturity Date, in an amount equal to the remainder of the principal amount

GUARANTOR CONSENT AND REAFFIRMATION 

[•], 2017 
 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
Loan Documents (as defined therein), and each of the other banks and financial institutions party thereto from time to time (collectively, the “Lenders” and individually, a “Lender”) and (b) the Second
Amendment to First Lien Credit Agreement, dated as of the date hereof, among Holdings, the Borrower, the Administrative Agent and the 2017 Incremental Term Loan Lender (as defined therein) party thereto (the “Second 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 Second Amendment, as applicable. 

Each Guarantor party hereto hereby consents to the terms and conditions of the Second Amendment, including the incurrence by the Borrower of
the 2017 Incremental Term Loans contemplated thereby, and agrees that each reference to the Credit Agreement in the Loan Documents shall, on and after the Second Amendment Effective Date, be deemed to be a reference to the Credit Agreement as
amended by the Second Amendment. 
 Each Guarantor hereby acknowledges and agrees that, after giving effect to the Second 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 Second Amendment, are reaffirmed, and remain in full force and effect. 
 After giving
effect to the Second Amendment, each Guarantor reaffirms (i) its guarantee of the Secured Obligations (including, without limitation, the 2017 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 Second Amendment, and shall continue to secure the Secured
Obligations (including, without limitation, the 2017 Incremental Term Loans), in each case, on and subject to the terms and conditions set forth in the Credit Agreement, as amended by the Second Amendment, and the other Loan Documents. 

Each Guarantor hereby acknowledges and agrees that neither the modification of the Credit Agreement effected pursuant to this Second Amendment
nor the execution, delivery, performance or effectiveness of this Second 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
Document and such Liens continue unimpaired with the same priority to secure repayment of all Secured Obligations, whether heretofore or hereafter incurred. 

Each Guarantor hereby acknowledges and agrees that (A) each Loan Document to which it is a party shall continue to be in full force and
effect and (B) all guarantees, pledges, grants of Liens, covenants, agreements and other commitments by such Loan Party under the Loan Documents shall continue to be in full force and effect and shall accrue to the benefit of the Secured
Parties and shall not be affected, impaired or discharged hereby or by the transactions contemplated in the Second Amendment. 












 Nothing in this Consent shall create or otherwise give rise to any right to consent on the
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
delivery of an original executed counterpart of this Consent.
