Capitalized terms used herein and not otherwise defined herein shall have the respective meanings given to them in the Credit Agreement.

WHEREAS, the Borrower has requested that the requisite Banks and the Administrative Agent agree to address certain provisions of the Credit Agreement in certain respects;

WHEREAS, the Borrower, the Lenders party hereto and the Administrative Agent have so agreed on the terms and conditions set forth herein;

NOW, THEREFORE, in consideration of the premises set forth above, the terms and conditions contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Borrower, the Lenders party hereto and the Administrative Agent hereby agree to enter into this Waiver and Consent.

1.Specified Defaults. The Borrower has informed the Lenders that Defaults or Events of Default may have occurred under the Credit Agreement as a result of (the items described in the following clauses (i) through (iv), the “Specified Defaults”):

(i) the breach of representations or warranties contained in Sections 6.13 and/or 6.18 of the Credit Agreement, due to (a) the Borrower’s failure to deliver financial statements (and related certifications) for (1) fiscal year 2016 and the interim periods therein and/or (2) the interim periods in fiscal year 2017, which in each case were true and complete as of the dates and the periods covered by such financial statements and prepared in accordance with GAAP; and/or (b) the Borrower’s failure to keep proper records and books of account in conformity with GAAP;

(ii) the failure to comply with Sections 5.3(a), 5.3(c) and/or 5.4 of the Credit Agreement, due to: (a) the Borrower’s failure to deliver financial statements (and related certifications) for (1) fiscal year 2016 and the interim periods therein and/or (2) the interim periods in fiscal year 2017, which in each case were true and complete as of the dates and the periods covered by such financial statements and prepared in accordance with GAAP; and/or (b) the Borrower’s failure to keep proper books of record and account in conformity with GAAP; and/or

(iii) the occurrence of an event or condition that enables or permits the holder or holders of any Indebtedness evidenced by a Material Indebtedness Agreement or any trustee or agent on its or their behalf, to accelerate the maturity of such Indebtedness or cause any such Indebtedness

to become due prior to its scheduled maturity, to the extent resulting from any of the items described in the foregoing clauses (i) or (ii) or any failure to deliver notices in connection therewith (any event or condition described in this clause (iii), the “Cross Default”); and/or

(iv) any failure to provide notice of a Default as required by Section 5.15 of the Credit Agreement with respect to any event described in the foregoing clauses (i) through (iii).

2.Waiver. Subject to the satisfaction of the conditions precedent set forth in Section 4 below, the Administrative Agent and the Banks party hereto hereby waive the occurrence of the Specified Defaults, provided that:

(a) it shall be a condition subsequent to the effectiveness of the waiver of the Cross Default that the Borrower shall, on or prior to December 30, 2017 (the “Outside Date”), obtain such waivers from applicable persons such that no holder or holders of any Indebtedness evidenced by a Material Indebtedness Agreement nor any trustee or agent on its or their behalf may accelerate the maturity of such Indebtedness or cause any such Indebtedness to become due prior to its scheduled maturity as a result of the occurrence of any Specified Default (and the Borrower shall have delivered to the Administrative Agent, on or prior to the Outside Date, a certificate certifying the satisfaction of such condition subsequent); and

(b) the waiver of the Cross Default shall not constitute a waiver of the occurrence of any event or condition that results in any Indebtedness evidenced by a Material Indebtedness Agreement becoming due prior to its scheduled maturity.

The waiver in this Section 2 applies only to the Specified Defaults and only for the periods and for the express circumstances described above, and shall not be construed to constitute (i) a waiver of any other event, circumstance or condition or of any other right or remedy available to the Administrative Agent, Fronting Bank or any Bank pursuant to the Credit Agreement or any other Loan Document or (ii) a course of dealing or a consent to any departure by the Borrower from any other term or requirement of the Credit Agreement.

3.Consent. The Borrower has informed the Lenders that it requires additional time to deliver its (a) audited consolidated financial statements for the fiscal year ended December 31, 2016 and other related information required by Section 5.3(b) of the Credit Agreement, as well as the related Compliance Certificate required by Section 5.3(c) of the Credit Agreement and (b) unaudited financial statements for the fiscal quarters ended March 31, 2017, June 30, 2017 and September 30, 2017 and other related information required by Section 5.3(a) of the Credit Agreement, as well as the related Compliance Certificates as required by Section 5.3(c) of the Credit Agreement (collectively, the “Required Financial Deliverables”). Subject to the conditions to effectiveness set forth in Section 4 below, the Administrative Agent and the Banks party hereto hereby consent to the delivery by or on behalf of the Borrower of the Required Financial Deliverables by no later than the Outside Date, in lieu of the date for delivery thereof specified in such Sections 5.3(b) and (c); provided that it shall be an Event of Default under the Credit Agreement if the Borrower fails to deliver any such Required Financial Deliverables by the Outside Date.

4.Conditions of Effectiveness. The effectiveness of this Waiver and Consent is subject to the conditions precedent that the Administrative Agent shall have received (i) counterparts of this Waiver and Consent duly executed by the Borrower, the Required Banks and the Administrative Agent and (ii) payment and/or reimbursement of the Administrative Agent’s and its affiliates’ fees and expenses (including, to the extent invoiced, the reasonable fees and expenses of counsel for the Administrative Agent) in connection with this Waiver and Consent.

8.Governing Law; Submission to Jurisdiction. This Waiver and Consent shall be construed in accordance with and governed by the law of the State of Ohio. Each Credit Party hereby irrevocably submits to the non‑exclusive jurisdiction of any Ohio state or federal court sitting in Cleveland, Ohio, over any action or proceeding arising out of or relating to this Waiver and Consent, and each Credit Party hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such Ohio state or federal court. Each Credit Party, on behalf of itself and its Subsidiaries, hereby irrevocably waives, to the fullest extent permitted by law, any objection it may now or hereafter have to the laying of venue in any action or proceeding in any such court as well as any right it may now or hereafter have to remove such action or proceeding, once commenced, to another court on the grounds of FORUM NON CONVENIENS or otherwise. Each Credit Party agrees that a final, non-appealable judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

9.Jury Trial Waiver. Each Credit Party, the Administrative Agent and each of the Banks waive, to the fullest extent permitted by applicable Law, any right to have a jury participate in resolving any dispute, whether sounding in contract, tort or otherwise, among the Credit Parties, the Administrative Agent and the Banks, or any thereof, arising out of, in connection with, related to, or incidental to the relationship established among them in
