Adjustments, if any, in the Applicable Margin shall be implemented quarterly, on a prospective basis, based upon Agent’s calculation of the prior quarter’s Fixed Charge Coverage Ratio commencing on March 31, 2017 and continuing on the last day of each fiscal quarter thereafter, effective as of the first day of the second month in the fiscal quarter immediately following such applicable quarter (i.e. February 1st, May 1st, August 1st and November 1st, as applicable). If an Event of Default has occurred and is continuing at the time any reduction in the Applicable Margin is to be implemented, that reduction shall be deferred until the first day of the first fiscal month following the date on which such Event of Default is waived or cured. Nothing set forth in this definition shall limit the applicability of the Default Rate upon the occurrence and during the continuance of an Event of Default.

If the Borrowers shall fail to deliver the financial statements, certificates and/or other information required under Section 9.8 by the dates required pursuant to such sections, each Applicable Margin shall be conclusively presumed to equal the highest Applicable Margin specified in the pricing table set forth above until the date of delivery of such financial statements, certificates and/or other information, at which time the rate will be adjusted based upon the Fixed Charge Coverage Ratio reflected in such statements.

If, as a result of any restatement of, or other adjustment to, the financial statements of Borrowers or for any other reason, Agent determines that (a) the Fixed Charge Coverage Ratio as previously calculated as of any applicable date was inaccurate, and (b) a proper calculation of the Fixed Charge Coverage Ratio would have resulted in different pricing for any period, then (i) if the proper calculation of the Fixed Charge Coverage Ratio would have resulted in higher pricing for such period, the Borrowers shall automatically and retroactively be delegated to pay to Agent, promptly upon demand by Agent, an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period; and (ii) if the proper calculation of the Fixed Charge Coverage Ratio would have resulted in lower pricing for such period, Lenders shall have no obligation to repay interest or fees to the Borrowers; provided, that, if as a result of any restatement or other event a proper calculation of the Fixed Charge Coverage Ratio would have

3

resulted in higher pricing for one or more periods and lower pricing for one or more other periods (due to the shifting of income or expenses from one period to another period or any similar reason), then the amount payable by the Borrowers pursuant to clause (i) above shall be based upon the excess, if any, of the amount of interest and fees that should have been paid for all applicable periods over the amounts of interest and fees actually paid for such periods.

“Availability Block” shall mean an amount equal to $5,000,000.

“Adjusted EBITDA” shall mean for any period the sum of (a) net income (or loss) of Holdings and its Subsidiaries on a consolidated basis for such period (excluding extraordinary gains), plus (b) all interest expense of Holdings and its Subsidiaries on a consolidated basis for such period, plus (c) all charges against income of Holdings and its Subsidiaries for such period for federal, state and local taxes plus (d) depreciation expenses for such period, plus (e) amortization expenses for such period, plus (f) non-cash income reduction adjustments derived from or related to stock-based compensation, plus (g) charges related to the write-down or impairment of foreign Receivables of the production technologies business line, Inventory and fixed assets for such period (up to a maximum amount of $44,435,000 for the fiscal year ending December 31, 2016), and, for the purposes of the calculation of Excess Cash Flow, all charges related to the write-down or impairment of Inventory and fixed assets (without limitation) for such period, plus (h) up to $2,000,000 severance costs related to any Permitted Business-Line Disposition and actually incurred or expense within ninety (90) days of any such Permitted Business-Line Disposition, plus (i) transaction costs and expenses related to the negotiation and execution of the Sixth Amendment and actually incurred or expensed within ninety (90) days of the Sixth Amendment Effective Date.

In the event Borrowers fail to reimburse Issuer for the full amount of any drawing under any Letter of Credit by 12:00 p.m., on the Drawing Date, Issuer will promptly notify Agent and each Lender holding a Revolving Commitment thereof, and Borrowers shall be automatically deemed to have requested that a Revolving Advance maintained as a Domestic Rate Loan be made by Lenders to be disbursed on the Drawing Date under such Letter of Credit, subject to the amount of the unutilized portion of the lesser of Maximum Revolving Advance Amount or the Formula Amount, less, in each case, the Maximum Undrawn Amount of all Letters of Credit and subject to Section 8.2 hereof. Any notice given by Issuer pursuant to this Section 2.14(b) may be oral if promptly confirmed in writing; provided, that, the lack of such a confirmation shall not affect the conclusiveness or binding effect of such notice.
