NOW THEREFORE, in consideration of the mutual conditions and agreements set forth in the Credit Agreement and this Amendment, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.     Amendments to the Credit Agreement. As of the Fourth Amendment Effective Date, the Credit Agreement is hereby amended as follows:

(a)     Section 1.01 of the Credit Agreement is hereby amended by adding the following defined terms, such terms to be incorporated into Section 1.01 of the Credit Agreement in the correct alphabetical order:

“Fourth Amendment” means that certain Fourth Amendment to Credit Agreement dated as of November 13, 2014, among the Administrative Agent, the Lenders and the Borrower.”

“Fourth Amendment Effective Date” means November 13, 2014.”

(b)     Section 2.01 of the Credit Agreement is hereby deleted in its entirety and the following new Section 2.01 is inserted in replacement therefor:

“2.01     Term Loans.     On the Closing Date, Lenders made a term loan to Borrowers (the “Original Term Loan”) in the original principal amount of $24,000,000, the principal balance of which was $4,352,136.76 as of the Second Amendment Effective Date. On the Second Amendment Effective Date, Lenders made an additional term loan to Borrowers in the original aggregate principal amount of $3,647,863.24 (the “Second Amendment Term Loan”; and together with the Original Term Loan, the “Existing Term Loans”). On July 11, 2014, Children's Trust c/u the Donald R. Wilson 2009 GRAT #1 (“DW Lender”) purchased from Comvest Capital II, L.P. (“Comvest”) a portion of the principal amount of Existing Term Loans equal to $4,000,000 and White Knight Capital Management LLC (“GS Lender”) purchased from Comvest a portion of the principal amount of Existing Term Loans equal to $4,000,000, in each case, pursuant to an Assignment and Acceptance Agreement dated July 11, 2014 (the transactions described in this sentence, the “Assignments”) and the GS Lender and the DW Lender made an additional loan to the Borrowers in the aggregate principal amount of $452,133.13 (the “Assignment Term Loan”), the proceeds of which were used to pay costs, fees and expenses in connection with the Assignments. On the terms and subject to the conditions set forth in the Credit Agreement and in the Third Amendment, on the Third Amendment Effective Date, each of DW Lender and GS Lender made an additional term loan to the Borrowers in the original aggregate principal amount of $3,547,866.87 (which was allocated 50% to GS Lender and 50% to DW Lender) (the “Third Amendment Term Loan”). On the terms and subject to the conditions set forth herein and in the Fourth Amendment, on the Fourth Amendment Effective Date, each of DW Lender and GS Lender shall make an additional term loan to the Borrowers in the original aggregate principal amount of $2,000,000.00 (which will be allocated 50% to GS Lender and 50% to DW Lender) (the “Fourth Amendment Term Loan”). Each of the Assignment Term Loan, the Third Amendment Term Loan and the Fourth Amendment Term Loan shall be deemed to be made in addition to the Existing Term Loans and not in repayment thereof and shall constitute a portion of the Term Loan for all purposes under the Credit Agreement and each Loan Document. Without limiting the generality of the foregoing, the Loans made pursuant to this Section 2.01 shall (i) constitute Obligations under the Loan Documents and have all of the benefits thereof, (ii) have all of the rights, remedies, privileges and protections applicable to the Term Loan under the Credit Agreement and the other Loan Documents, (iii) be secured by the Liens granted to the Administrative Agent under any Loan Document, (iv) be evidenced by notes, if requested by the applicable Lender and (v) bear interest at rates applicable to the Term Loan under the Credit Agreement. Moreover, effective immediately upon making its portion of the Fourth Amendment Term Loan hereunder, each of DW Lender and GS Lender shall automatically become a party to the Credit Agreement (as amended by the Fourth Amendment) as a “Lender” and have all rights and obligations of a Lender thereunder, without any further action by Administrative Agent, any other Lender or any Loan Party. After giving effect to the making of the Fourth Amendment Term Loan pursuant to this Section 2.01, the Existing Term Loans, the Assignment Term Loan, the Third Amendment Term Loan and the Fourth Amendment Term Loan shall be consolidated into a single term loan hereunder (the “Term Loan”). Each Borrower hereby acknowledges and agrees that the principal amount of the Term Loan outstanding under the Credit Agreement on the Fourth Amendment Effective Date (after giving effect to the funding of the Fourth Amendment Term Loan) is $14,000,000 (which is allocated as follows: $7,000,000 to GS Lender and $7,000,000 to DW Lender).

2.     Conditions to Effectiveness. The effectiveness of Section 1 of this Amendment is subject to the following conditions precedent:

6.     References. Any reference to the Credit Agreement contained in any document, instrument or Loan Document executed in connection with the Credit Agreement shall be deemed to be a reference to the Credit Agreement as modified by this Amendment.

7.     Counterparts. This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Amendment by telecopier or pdf shall be equally as effective as delivery of an original executed counterpart of this Amendment. Any party delivering an executed counterpart of this Amendment by telecopier or pdf shall also deliver an original executed counterpart of this Amendment but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Amendment.

8.     Ratification. The terms and provisions set forth in this Amendment shall modify and supersede all inconsistent terms and provisions of the Credit Agreement and shall not be deemed to be a consent to the modification or waiver of any other term or condition of the Credit Agreement. Except as expressly modified and superseded by this Amendment, the terms and provisions of the Credit Agreement are ratified and confirmed and shall continue in full force and effect.

9.     Governing Law. This Amendment shall be governed by, and construed in accordance with, the law of the State of New York applicable to contracts made and to be performed in the State of New York.

10.   Reaffirmation. Each of the Loan Parties as debtor, grantor, pledgor, guarantor, assignor, or in other any other similar capacity in which such Loan Party grants liens or security interests in its property or otherwise acts as accommodation party or guarantor, as the case may be, hereby (i) ratifies and reaffirms all of its payment and performance obligations, contingent or otherwise, under each of the Loan Documents to which it is a party (after giving effect hereto) and (ii) to the extent such Loan Party granted liens on or security interests in any of its property pursuant to any such Loan Document as security for or otherwise guaranteed the Borrowers’ Obligations under or with respect to the Loan Documents, ratifies and reaffirms such guarantee and grant of security interests and liens and confirms and agrees that such security interests and liens hereafter secure all of the Obligations as amended hereby. Each of the Loan Parties hereby consents to this Amendment and acknowledges that each of the Loan Documents remains in full force and effect and is hereby ratified and reaffirmed. The execution of this Amendment shall not operate as a waiver of any right, power or remedy of the Administrative Agent or Lenders, constitute a waiver of any provision of any of the Loan Documents or serve to effect a novation of the Obligations.
