WITNESSETH: 

WHEREAS, pursuant to the Credit Agreement, the Lenders have extended the time for the delivery of (i) the audited financial statements of
the Borrower for the fiscal year ended March 31, 2015, certified by independent certified public accountants in accordance with Section 8.3.2 [Annual Financial Statements] of the Credit Agreement (the “2015 Audited Financial
Statements”), and (ii) the financial statements of the Borrower for the fiscal quarter ended June 30, 2015, (the “Q1 Quarterly Financial Statements”) and the financial statements of the Borrower for the fiscal
quarter ended September 30, 2015 (the “Q2 Quarterly Financial Statements”), each to be delivered in accordance with Section 8.3.1 [Quarterly Financial Statements] of the Credit Agreement. 

WHEREAS, the Borrower and the Guarantors have requested (i) that the Lenders provide an additional extension of time for the delivery of
the 2015 Audited Financial Statements, the Q1 Quarterly Financial Statements and the Q2 Quarterly Financial Statements, and (ii) that the Lenders provide an extension of time for the delivery of the financial statements of the Borrower for the
fiscal quarter ended December 31, 2015, (the “Q3 Quarterly Financial Statements). 
 NOW, THEREFORE, the parties hereto, in
consideration of their mutual covenants and agreements herein contained and intending to be legally bound hereby, covenant and agree as follows: 

1. Definitions. Capitalized terms used but not defined herein shall have the meanings set forth in the Credit Agreement. 

2. Amendments to Credit Agreement. 

The following new definitions are hereby inserted in Section 1.1 [Certain Definitions] of the Credit Agreement in alphabetical order: 

“Fourth Amendment shall mean the Fourth Amendment to Amended and Restated Credit Agreement, dated as of February 17,
2016.” 







 “Fourth Amendment Effective Date shall mean the date upon which the Fourth Amendment
became effective pursuant to its terms.” 
 3. Extension of Financial Reporting. In accordance with Section 11.1
[Modifications, Amendments or Waivers] of the Credit Agreement, the Administrative Agent and the Lenders hereby consent to the delivery by the Borrower of the 2015 Audited Financial Statements, the Q1 Quarterly Financial Statements, the Q2 Quarterly
Financial Statements and the Q3 Quarterly Financial Statements on or prior to April 1, 2016. If the Borrower fails to deliver the 2015 Audited Financial Statements, the Q1 Quarterly Financial Statements, the Q2 Quarterly Financial Statements
and the Q3 Quarterly Financial Statements to the Administrative Agent on or before 11:59 P.M. (Pittsburgh, Pennsylvania time) on April 1, 2016, such default shall constitute an Event of Default without regard to any grace period otherwise
provided with respect violations of Section 9.1.4 of the Credit Agreement. The Administrative Agent and the Lenders hereby waive any Potential Default (including a Potential Default of Section 8.3.4.1 relating to required certification)
resulting from the Loan Parties’ non-compliance with the provisions of the Credit Agreement with respect to the foregoing. The consents of the Lenders described in this paragraph are limited to the specific covenants referenced and do not
constitute a consent to the waiver of any other covenant or provision of the Credit Agreement or any other Loan Document, nor do such consents indicate any agreement on the part of the Lenders to grant any such consent in the future. 

4. Consent. On May 6, 2015, the Borrower declared a cash dividend of $0.0195 per share for payment to the ESOP with respect to the
preferred shares of the Borrower held in the ESOP (the “ESOP Dividend”). The declaration of the dividend to the ESOP subsequently was not permitted by Section 8.2.5 [Capital Distributions] of the Credit Agreement as a result of
the existence of a Potential Default. The Borrower has requested the consent of the Administrative Agent and Lenders to the ESOP Dividend. In accordance with Section 11.1 [Modifications, Amendments or Waivers] of the Credit Agreement, the
Administrative Agent and the Lenders hereby consent to the ESOP Dividend. The Administrative Agent and the Lenders hereby waive any Potential Default or Event of Default resulting from the Loan Parties’ non-compliance with the provisions of the
Credit Agreement with respect to the foregoing. The consents of the Lenders described in this paragraph are limited to the specific covenants and dividend referenced and do not constitute a consent to the waiver of any other covenant or provision of
the Credit Agreement or any other Loan Document, nor do such consents indicate any agreement on the part of the Lenders to grant any such consent in the future. 

5. Amendment Fee. The Borrower hereby agrees to pay a fee in the amount of $15,000 to each Lender which has executed and delivered this
Fourth Amendment to the Administrative Agent on or before 5:00 p.m. Eastern time on February 19, 2016, which fee shall be deemed to be earned on the Fourth Amendment Effective Date.

transactions contemplated hereby and supersedes all prior understandings and agreements, whether written or oral, between the parties hereto relating to the subject matter hereof. No representation, promise, inducement or statement of intention has
been made by any party which is not embodied in this Fourth Amendment, and no party shall be bound by or liable for any alleged representation, promise, inducement or statement of intention not set forth herein.

purposes shall be governed by and construed and enforced in accordance with the internal laws of the State of Ohio, U.S.A. without regard to its conflict of laws principles.
