NOW, THEREFORE, in consideration of the mutual promises, covenants and agreements herein contained, the parties agree as follows:

Any capitalized term not otherwise defined herein shall have the meaning set forth in the Loan Agreement.

“ “Hedging Contract” means any and all rate swap transactions, foreign exchange transactions, credit derivative transactions and commodity transactions, including, but not limited to, basis swaps, forward rate transactions, commodity swaps, commodity options, forward commodity contracts, equity or equity index swaps or options, bond or bond price or bond index swaps or options or forward bond or forward bond price or forward bond index transactions, interest rate options, forward foreign exchange transactions, cap transactions, floor transactions, collar transactions, currency swap transactions, cross-currency rate swap transactions, currency options, spot contracts, or any other similar transactions or any combination of any of the foregoing (including any options to enter into any of the foregoing), whether or not any such transaction is governed by or subject to any master agreement, whether with Lender or any affiliate of Lender, now existing or hereafter arising.

2.2 Section 3.1. The second to last sentence of Section 3.1 is hereby amended and restated in its entirety to read as follows:

“As used in this Section 3, “Borrowers’ Availability” means an amount equal to the revolving line of credit approved by Lender, reduced by (a) the face amount of any Letters of Credit issued by the Lender and/or its Affiliates and (b) the amount outstanding under the term sublimit described below. All advances made by Lender under the Revolving Credit Loan, shall be payable as provided in the Revolving Credit Note which is incorporated hereby by reference;”

2.3 Add the following new Section 3.11:

“3.11 Term Sublimit. So long as no Event of Default has occurred hereunder or no event, but for the passage of time or giving of notice or both would constitute an Event of Default, Borrowers may request to convert up to Eight Million Dollars ($8,000,000) of the revolving line of credit to fund up to one hundred percent (100%) of the cost of CAPEX. An initial conversion under the term sublimit in the amount of up to Two Million Five Hundred Thousand Dollars ($2,500,000) shall be made on the date hereof. All future requests for conversions under the term sublimit shall be made on or before that day which is two (2) business days prior to December 31. In no event shall the maximum funded amount under the term sublimit exceed Five Million Dollars ($5,000,000) during the calendar year of 2013 and Eight Million Dollars ($8,000,000) during the 2014 calendar year (each, as applicable, the Term Sub-limit Availability). All amounts outstanding on the term sublimit will be subtracted from Borrowers’ Availability. Requests for conversions under the term sublimit shall be accompanied by a certification and breakdown of the CAPEX funded under the conversion. No conversion shall exceed one hundred percent (100%) of the cost of the CAPEX.

(a) An account shall be opened on the books of Lender (hereinafter the “Term Sub-limit Account”), in which account a record shall be kept of the conversions made by Lender to Borrowers under or pursuant to the Term Sub-limit, and all payments made by or on behalf of Borrowers with respect to the Term Sub-limit. Borrowers hereby authorize Lender to debit account # 3310580964 monthly for all amounts due to Lender under the Term Sub-limit;

(b) Lender may also keep a record (either in the Term Sub-limit Account or elsewhere, as Lender may from time to time elect) of all interest, service charges, costs, expenses and other debits owed Lender on account of the Term Sub-limit contemplated hereby and of all credits against such amounts so owed;

(c) All credits against Borrowers’ indebtedness indicated in the Term Sub-limit Account shall be conditional upon final payment to Lender of the items giving rise to such credits. The amount of any item credited against the Term Sub-limit Account which is not so paid or which is charged back against Lender for any reason may be charged as a debit to the Term Sub-limit Account, may be charged back against any deposit account maintained by Borrowers with Lender, and shall be an obligation, in each instance whether or not the item so charged back or not so paid is returned; and

(d) Any statement rendered by Lender to Borrowers shall be considered correct and accepted by Borrowers, and shall be conclusively binding upon Borrowers unless Borrowers provide Lender written objection thereto within ninety (90) business days from the mailing of such statement, which written objection shall indicate, with particularity, the reason for such objection;

(e) Borrowers shall have the option of entering into Hedging Contracts for conversions made under the term sublimit.”

2.4 Schedule 6.11 (all real estate owned or leased by Borrower) is replaced in its entirety with the Schedule 6.11 attached hereto.

2.5 Schedule 6.12 (all Proprietary Rights) is hereby replaced in its entirety with the Schedule 6.12 attached hereto and Borrower hereby reaffirms and grants to Lender a security interest in all Proprietary Rights.

2.6 Section 7.9.1 Section 7.9.1 is replaced in its entirety with the following:

“7.9.1 maintain a ratio of Funded Debt to EBITDA of not more than the following, which shall be tested and measured quarterly on a trailing four (4) quarter basis:

Commencing on December 31, 2015 and at each fiscal year end thereafter, each quarterly ratio shall decrease by .25%.”

2.7 Section 7.9.3 Section 7.9.3 is hereby amended and restated in its entirety to read as follows:

“7.9.3 maintain a Fixed Charge Coverage Ratio of not less than 1.20 to 1.00, which shall be tested and measured quarterly on a trailing four (4) quarter basis.

For purposes of measuring this ratio, (a) CAPEX internally funded shall only be included to the extent that such amount is either not converted to a term loan under the term sub-limit and/or exceeds the Term Sublimit Availability as defined in Section 3.11 above and (b) all non-cash income and non-cash losses attributable to Hedging Contracts will be excluded from the calculation.”

2.8 Lender waives Borrower’s failure to comply with Section 8.13 in 2012. Borrower must comply with Section 8.13 going forward and agrees to use best efforts to obtain landlord waivers and consents and applicable leases for all locations shown on Schedule 6.11 as well as the Littleton Warehouse.

This Amendment is subject to the condition (in addition to all requirements of the Loan Agreement and all other Loan Documents, as they may be amended) that each of the following shall have been delivered or performed to the satisfaction of Lender:

3.1 Execution and/or delivery of this Amendment, an Amendment to the Revolving Credit Note and any other documents, consent or other matters required by Lender, including those contained on the Closing Agenda attached hereto as Schedule 3.1.

3.2 Payment of an origination fee to Lender for the extension of the Revolving Line of Credit Loan in the amount of Thirteen Thousand Dollars ($13,000.00) and a modification fee in the amount of $1,500.00.

3.3 Borrowers will pay all of Lender’s costs and expenses incurred in preparation of this Amendment and the documents and instruments executed herewith.

In all other respects, the Loan Agreement remains in full force and effect, and Borrowers agree to be bound thereby. Except as specifically amended herein, the terms and conditions of the Loan Agreement shall remain in full force and effect. Borrowers confirm and agree that the amendments contained herein shall in no way be construed as an obligation on the part of Lender to further amend or extend the Loan Agreement or any other Loan Documents. This Amendment is not a novation.

Borrowers reaffirm each and every representation and warranty made by them in the Loan Agreement. Borrowers and Lender hereby agree and confirm that Borrowers have prior to this Amendment delivered to Lender the information and disclosures in accordance with the reporting requirements of the Loan Agreement.

Borrowers warrant that it has full power and authority, and has taken all necessary corporate and other action and procured all necessary consents to execute and deliver this Amendment and perform its obligations hereunder.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly executed on their behalf by the persons signing below who are thereunto duly authorized, as of the day and year first above-written.
