WHEREAS, a revolving credit facility has been extended to the Borrower pursuant to the Credit Agreement (as amended, modified, supplemented, increased and extended from time to time, the “Credit Agreement”) dated as of September 26, 2013 among the Borrower, the Guarantors identified therein, the Lenders identified therein and the Administrative Agent;

WHEREAS, the Borrower has failed to comply with Sections 7.01(a), 7.01(b), 7.02(a), 7.02(b) and 7.02(d) of the Credit Agreement with respect to the fiscal year ending December 31, 2015 and the fiscal quarter ending March 31, 2016 by failing to deliver the financial statements required by Section 7.01(a) or 7.01(b) of the Credit Agreement and the related certificates required by Sections 7.02(a), (b) and (d) of the Credit Agreement, within the time periods permitted in the Credit Agreement (as amended by the Waiver and Third Amendment to the Credit Agreement)(together with any other breaches of representations, warranties or covenants caused exclusively as a result of the Borrower not timely filing financial reporting documents with respect to the fiscal year ending December 31, 2015 and the fiscal

quarter ending March 31, 2016, the “Existing Reporting Events of Default”), which failures constitute Events of Default under Section 9.01(b)(i) of the Credit Agreement;

WHEREAS, the Borrower has requested that the Required Lenders (a) waive the Existing Events of Default and (b) agree to certain modifications to the Credit Agreement; and
