AGREEMENT

NOW, THEREFORE, in consideration of the foregoing recitals and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, and intending to be legally bound, the parties hereto agree as follows:

1. Definitions. Capitalized terms used but not defined in this Amendment shall have the meanings given to them in the Loan Agreement.

2. Amendments to Loan Agreement.

2.1 Section 2.1.3 (Equipment Advances). Section 2.1.3 is added to the Loan Agreement to read as follows:

2.1.3 Equipment Advances.

(a) Availability. Subject to the terms and conditions of this Agreement, Borrower may request, and Bank agrees to make, advances (each an “Equipment Advance” and, collectively, the “Equipment Advances”) to Borrower until December 31, 2014, in an aggregate amount not to exceed Three Million Dollars ($3,000,000). Equipment Advances may finance up to 100% of the cost of Eligible Equipment and up to 25% of Other Equipment. Each Equipment Advance, other than the final Equipment Advance, must be in an amount of not less than Five Hundred Thousand Dollars ($500,000). After repayment, no Equipment Advance may be reborrowed.

(b) Procedures for Borrowing. Borrower will deliver a completed Payment/Advance Form with each request for an Equipment Advance, together with invoices and such other information in respect of the Equipment to be financed as Bank reasonably requests. On the Funding Date, if Borrower satisfies the conditions hereunder, Bank shall disburse such Equipment Advance by transfer to the Designated Deposit Account. Bank may rely on information set forth in, or provided with, the Payment/Advance Form. Bank may make Equipment Advances based on instructions from a Responsible

Officer or his or her designee. Bank may rely on any telephone notice given by a person whom Bank reasonably believes is a Responsible Officer or designee. Borrower shall indemnify Bank for any loss Bank suffers due to such reliance.

(c) Repayment. Borrower shall repay each Equipment Advance in 36 equal monthly installments of principal and interest, beginning on the first Business Day of the first month after the Funding Date thereof, and continuing until such Equipment Advance has been repaid in full. Borrower may prepay all or any part of an Equipment Advance without penalty or premium, each prepayment to be applied first to interest, then to principal installments in reverse order of maturity.

2.2 Section 2.3 (Payment of Interest on the Credit Extensions.) A new paragraph (iii) is added to paragraph (a) and a new paragraph (e) is added to Section 2.3 of the Loan Agreement to read as follows:

(iii) Equipment Advances. Subject to Section 2.3(b), the principal amount outstanding under each Equipment Advance shall accrue interest, which interest shall be payable monthly in accordance with Section 2.3(d) below, at a floating per annum rate equal to one-half of one percent (0.5%) above the WSJ Prime Rate.

(e) Minimum Interest. In the event the aggregate amount of interest earned by Bank on account of the Advances in any calendar quarter (such period, the “Minimum Interest Period”) is less than the interest that would accrue on an outstanding principal balance of $2,000,000 of Advances (exclusive of any collateral monitoring fees, unused line fees, or any other fees and charges hereunder) (“Minimum Interest”), Borrower shall pay to Bank, upon demand by Bank, an amount equal to the (i) Minimum Interest minus (ii) the aggregate amount of all interest earned by Bank in such Minimum Interest Period. For any Minimum Interest Period in which the average daily balance in Borrower’s account(s) with Bank and Bank’s affiliates exceeds $50,000,000, the Minimum Interest shall be equal to the interest that would accrue on an outstanding principal balance of $1,000,000 of Advances. The amount of Minimum Interest charged shall be prorated for any partial Minimum Interest Period. Bank may deduct amounts owing by Borrower under this Section 2.3(e) pursuant to the terms of Section 2.5(c). Bank shall provide Borrower written notice of deductions made from the Designated Deposit Account pursuant to the terms of this Section 2.3(e).

2.3 Section 6.2 (Financial Statements). Paragraph (d) of Section 6.2 of the Loan Agreement is amended to read as follows: (d) Annual Audited Financial Statements. Beginning with Borrower’s 2014 fiscal year, audited consolidated financial statements prepared in accordance with GAAP, consistently applied, together with an unqualified opinion thereon by an independent certified public accounting firm acceptable to Bank in its reasonable discretion shall be due within one hundred eighty (180) days after the last day of Borrower’s fiscal year, but in any event no later than ten (10) days after completion.

2.4 Section 6.9 (Financial Covenants). Section 6.9 of the Loan Agreement is amended to read as follows:

Maintain consolidated revenues equal at least to the Proposed Monthly Revenue Covenant set forth on attached Schedule A, measured as of the last day of each month, beginning with the three months ended March 31, 2014, measured on a cumulative basis until there are sufficient months to measure performance on a trailing six-month basis, and measured thereafter on a trailing six-month basis. For fiscal year 2015, revenue shall be equal at least to 80% of the revenue projected in the business plan approved by Borrower’s Board of Directors, measured on a trailing six-month basis, as long as the required covenant shows not less than 15% growth from the comparable period in 2015.
