RECITALS

The Borrower and the Lender are parties to a Second Amended and Restated Credit and Security Agreement dated August 14, 2013 (as amended from time to time, the “Credit Agreement”). Capitalized terms used in these recitals have the meanings given to them in the Credit Agreement unless otherwise specified.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants and agreements herein contained, it is agreed as follows:

1. Credit Agreement Amendment. The Credit Agreement is hereby amended as follows:

(a) The definition of “Default Rate” contained in Section 1.1 of the Credit Agreement is hereby deleted and replaced as follows:

“Default Rate” means an annual interest rate equal to three percent (3%) over the Floating Rate, which interest rate shall change when and as the Floating Rate changes.

(b) The definition of “Floating Rate” contained in Section 1.1 of the Credit Agreement is hereby deleted and replaced as follows:

“Floating Rate” means, with respect to all Advances (except the Real Estate Term Advance) an interest rate equal to the sum of (i) Daily Three Month LIBOR, which interest rate shall change whenever Daily Three Month LIBOR changes, plus (ii) three percent (3.00%) and, with respect to the Real Estate Term Advance, “Floating Rate” means an interest rate equal to the sum of (i) Daily Rate equal to Three Month LIBOR, which interest rate shall change whenever the Daily Three Month LIBOR changes, plus (ii) four percent (4.00%).

“LIBOR” means the rate per annum determined pursuant to the following formula:

(a) “Base LIBOR” means the rate per annum for United States dollar deposits quoted by Lender for the purpose of calculating the

1

effective Floating Rate for loans that reference Daily Three Month LIBOR as the Inter-Bank Market Offered Rate in effect from time to time for three (3) month delivery of funds in amounts approximately equal to the principal amount of such loans. Borrower understands and agrees that Lender may base its quotation of the Inter-Bank Market Offered Rate upon such offers or other market indicators of the Inter-Bank Market as Lender in its discretion deems appropriate, including but not limited to the rate offered for U.S. dollar deposits on the London Inter-Bank Market.

(b) “LIBOR Reserve Percentage” means the reserve percentage prescribed by the Board of Governors of the Federal Reserve System (or any successor) for “Eurocurrency Liabilities” (as defined in Regulation D of the Federal Reserve Board, as amended), adjusted by Lender for expected changes in such reserve percentage during the applicable term of the Revolving Note.

(d) The definition of “Maturity Date” contained in Section 1.1 of the Credit Agreement is hereby deleted and replaced as follows:

“Maturity Date” means April 30, 2019.

(e) The definition of “Real Estate Facility Maturity Date” contained in Section 1.1 of the Credit Agreement is hereby deleted and replaced as follows:

“Real Estate Facility Maturity Date” means April 30, 2019

(f) The definition of “Term Floating Rate” contained in Section 1.1 of the Credit Agreement is hereby deleted without replacement.

(g) Section 2.8(a) of the Credit Agreement is hereby deleted and replaced as follows:

(a) Note. Except as set forth in subsections (b) and (d), the outstanding principal balance of the Revolving Note and each Revolving Advance and the outstanding principal balance of the Real Estate Term Note and the Real Estate Term Advance shall bear interest at the Floating Rate.

(h) Section 2.9(e) of the Credit Agreement is hereby deleted and replaced as follows:

(e) Termination and Line Reduction Fees. If (i) the Lender terminates the Credit Facility as a result of the occurrence of an Event of Default, or if (ii) the Borrower terminates the Credit Facility or reduces the Maximum Line on a date prior to the Maturity Date, then the Borrower shall pay the Lender as liquidated damages and not as a penalty a termination fee in an amount equal to a percentage of the Maximum Line (or the reduction of the Maximum Line, as the case may be) calculated as follows: (A) three percent (3.0%) if the termination or reduction occurs on or before April 30, 2016; (B) two percent (2.0%) if the    

2

termination or reduction occurs after April 30, 2016 but on or before April 30, 2017; and (C) one percent (1.0%) if the termination or reduction occurs after April 30, 2018.

(i) Section 2.9(j) of the Credit Agreement is hereby deleted and replaced as follows:

Real Estate Term Advance Prepayment Fee. If the Real Estate Term Advance is prepaid in whole or in part prior to the Real Estate Facility Maturity Date for any reason, then on the date of any such prepayment, the Borrower shall pay to the Lender as liquidated damages and not as a penalty a prepayment fee in an amount equal to (i) three percent (3.0%) of the amount prepaid, if prepayment occurs on or before April 30, 2016; (ii) two percent (2.0%) of the amount prepaid, if prepayment occurs after April 30, 2016 but on or before April 30, 2018 and (iii) one percent (1.0%) of the amount prepaid if the prepayment occurs after April 30, 2018. No prepayment fee shall be due in connection with the paydown of the outstanding principal balance of the Real Estate Term Advance to $5,000,000.00.

(j) Section 2.11 (a)(i) of the Credit Agreement is hereby deleted and replaced as follows:

(i) If an Event of Default occurs and the Lender requests that the Borrower do so, or regardless of whether or not an Event of Default or Default Period exists, if the sum of Availability plus Cash and Cash Equivalents on deposit with Lender at any time is less than $7,500,000.00 (which amount shall be determined without regard to any applicable Availability block) for five consecutive business days, then in either event (A) the Borrower shall instruct all account debtors to pay all its Accounts directly to a lockbox (the “Lockbox”) established with Wells Fargo Bank or another bank selected by the Lender and reasonably satisfactory to the Borrower and (B) the Borrower shall execute and deliver to the Lender a lockbox agreement in form and substance satisfactory to the Lender in its sole and absolute judgment. If, notwithstanding such instructions, the Borrower receives any payments on their Accounts, the Borrower shall deposit such payments into a collateral account maintained with Lender (the “Collateral Account”). The Borrower shall also deposit all other cash proceeds of Collateral directly to the Collateral Account if received at a time that the Borrower is required to deposit payments on their Accounts into the Collateral Account. In addition, and regardless of whether or not an Event of Default or Default Period exists, if the sum of Availability plus Cash and Cash Equivalents on deposit with Lender at any time is less than $7,500,000.00 (which amount shall be determined without regard to any applicable Availability block) for five consecutive business days, then in such event, all proceeds of Collateral received by Borrower shall be immediately deposited in the Collateral Account. In all such events, until so deposited, the Borrower shall hold all

3

such payments and cash proceeds received by it in trust for and as the property of the Lender and shall not commingle such property with any of its other funds or property. All deposits in the Collateral Account shall constitute proceeds of Collateral and shall not constitute payment of the Obligations.

(k) Section 2.19 of the Credit Agreement is hereby deleted and replaced as follows:

Section 2.19

(a) Real Estate Term Advance. Lender has made a term loan to Borrower in the amount of $10,000,000.00 (the “Real Estate Term Advance”). The Borrower’s obligation to pay the Real Estate Term Advance shall be evidenced by the Real Estate Term Note and shall be secured by the Collateral.

(b) Payment of the Real Estate Term Advance. The outstanding principal balance of the Real Estate Term Advance shall be due and payable as follows:

(i) In equal monthly installments of $52,084.00, beginning on May 1, 2014, and on the 1st day of each month thereafter.

(ii) All prepayments of principal (including the prepayment referenced in Section 2.19(a) above) with respect to the Real Estate Term Advance shall be applied to the principal installments thereof in the inverse order of maturity.

(iii) On the Real Estate Facility Termination Date, the entire unpaid principal balance of the Real Estate Term Advance, and all unpaid interest accrued thereon, shall also be fully due and payable.

(l) Subsection 6.1(c) of the Credit Agreement is hereby deleted and replaced as follows:

(c) Collateral Reports. Monthly, or more frequently if the Lender so requires, the Borrower shall deliver to the Lender a calculation of the Borrowing Base showing in reasonable detail the respective amounts of Eligible Accounts and Eligible Inventory as of the date of the reporting, provided however, in the event that the sum of Availability plus Cash and Cash Equivalents on deposit with Lender at any time is less than $7,500,000.00 (which amount shall be calculated without regard to any applicable Availability block), said reporting shall be provided once every other week or more frequently if the Lender so requires.

2. No Other Changes. Except as explicitly amended by this Amendment, all of the terms and conditions of the Credit Agreement shall remain in full force and effect and shall apply to any advance or letter of credit thereunder.
