	2.	Incremental Term Loan: 

 a. The parties hereto hereby acknowledge and agree that the term

paid in full no later than the Tranche B-2 Term Loan Maturity Date. 

 In addition, the principal amount of Incremental
Term Loans, together with the existing Tranche B-2 Term Loans shall be repaid in consecutive quarterly installments in an aggregate amount equal to $2,315,256.89 with the next payment on March 31, 2014 and then quarterly thereafter as
provided in Section 2.12 of the Credit Agreement and Section 2.12 of the Credit Agreement is hereby amended to reflect such amounts as the Installments of Tranche B-2 Term Loans payable on each Installment Date commencing on
March 31, 2014 as set forth therein and that the unpaid balance of all Tranche B-2 Term Loans, including the Incremental Term Loans hereunder, shall be due and payable on the Maturity Date.
