The entire principal balance of the 2017 Term Loan Advance and all accrued but unpaid interest hereunder, and all other Secured Obligations with respect to the 2017 Term Loan Advance, shall be due and payable on the Term Loan Maturity Date. Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense. Lender will initiate debit entries to the Borrower’s account as authorized on the ACH Authorization on each payment date of all periodic obligations payable to Lender under the 2017 Term Loan Advance.

Proceeds of any Advance shall be deposited into an account that is subject to a perfected security interest in favor of Agent perfected by a control agreement.

(b) Advance Request. To obtain the Optional Term Loan Advance, Borrower shall complete, sign and deliver to Agent an Advance Request (at least thirty (30) days before the Advance Date). If, in its sole and absolute discretion, it elects to do so, Lender shall fund the Optional Term Loan Advance in the manner requested by the Advance Request provided that each of the conditions precedent to such Optional Term Loan Advance contained in Section 4 is satisfied as of the requested Advance Date.

(c) Interest. The principal balance of the Optional Term Loan Advance shall bear interest thereon from such Advance Date at the Term Loan Interest Rate based on a year consisting of 360 days, with interest computed daily based on the actual number of days elapsed. The Term Loan Interest Rate will float and change on the day the Prime Rate changes from time to time.

(d) Payment. Borrower will pay interest on the Optional Term Loan Advance on the first (1st) Business Day of each month, beginning the month after the Advance Date. Commencing on the Third Amendment Amortization Date, and continuing on the first (1st) Business Day of each month thereafter, Borrower shall repay the aggregate principal balance of the Optional Term Loan Advance that is outstanding on the day immediately preceding the Third Amendment Amortization Date, in equal monthly installments of principal and interest (mortgage style) based upon an amortization schedule equal to twenty-seven (27) months. After any change in the effective rate hereunder, Agent shall recalculate future payments of principal and interest to fully amortize the outstanding principal amount over the remaining scheduled monthly payments hereunder prior to the Term Loan Maturity Date. The entire principal balance of the Optional Term Loan Advance and all accrued but unpaid interest hereunder, and all other Secured Obligations with respect to the Optional Term Loan Advance, shall be due and payable on the Term Loan Maturity Date. Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense. Lender will initiate debit entries to the Borrower’s account as authorized on the ACH Authorization on each payment date of all periodic obligations payable to Lender under the Optional Term Loan Advance. Once repaid, the Optional Term Loan Advance or any portion thereof may not be reborrowed.”

(h) The last two sentences set forth in Section 2.3 (Default Interest) are amended in their entirety and replaced with the following:

“In addition, upon the occurrence and during the continuation of an Event of Default hereunder, all Secured Obligations, including principal, interest, compounded interest, and professional fees, shall bear interest at a rate per annum equal to the rate set forth in Section 2.1(c), Section 2.1.1(c), Section 2.1.1.1(c) or Section 2.1.1.1.1(c), as applicable, plus three and one half of one percent (3.5%) per annum. In the event any interest is not paid when due hereunder, delinquent interest shall be added to principal and shall bear interest on interest, compounded at the rate set forth in Section 2.1(c), Section 2.1.1(c), Section 2.1.1.1(c) or Section 2.1.1.1.1(c), as applicable.”

(i) Section 2.4 (Prepayment) is amended in its entirety and replaced with the following:

“ 2.4 Prepayment. At its option upon at least seven (7) Business Days prior notice to Agent, Borrower may prepay all, or any portion, of the outstanding Advances by paying the entire principal balance or a portion thereof, all accrued and unpaid interest on the portion prepaid, all unpaid Agent’s and Lender’s fees and expenses accrued to the date of the repayment (including the End of Term Charge, the 2016 End of Term Charge, the 2017 End of Term Charge and the Optional Term Loan End of Term Charge), together with a prepayment charge on the portion prepaid equal to the following percentage of the Advance amount being prepaid: if such Advance amounts are prepaid on or prior to July 1, 2018, two percent (2.00%); and if any such Advance amounts are prepaid after July 1, 2018, zero percent (0.00%) (each, a “Prepayment Charge”). Borrower agrees that the Prepayment Charge is a reasonable calculation of Lender’s lost profits in view of the difficulties and impracticality of determining actual damages resulting from an early repayment of the Advances. Upon the occurrence of a Change in Control, Borrower shall prepay the outstanding amount of all principal and accrued interest through the prepayment date and all unpaid Agent’s and Lender’s fees and expenses accrued to the date of the repayment (including the End of Term Charge, the 2016 End of Term Charge, the 2017 End of Term Charge and the Optional Term Loan End of Term Charge) together with the applicable Prepayment Charge.”

(j) Section 2.5 (End of Term Charge) is amended in its entirety and replaced with the following:

“ 2.5 End of Term Charge. (a) On the earliest to occur of (i) February 1, 2018, (ii) the date that Borrower prepays the outstanding Secured Obligations relating to the Term Loan Advances, or (iii) the date that the Secured Obligations relating to the Term Loan Advances become due and payable, Borrower shall pay Lender the End of Term Charge (provided that notwithstanding the required payment date of the End of Term Charge, it shall be deemed earned by Lender as of the Closing Date), (b) on the earliest to occur of (i) February 1, 2018, (ii) the date that Borrower prepays the outstanding Secured Obligations relating to the 2016 Term Loan Advances, or (iii) the date that the Secured Obligations relating to the 2016 Term Loan Advances become due and payable, Borrower shall pay Lender the 2016 End of Term Charge (provided that notwithstanding the required payment date of the 2016 End of Term Charge, it shall be deemed earned by Lender as of the 2016 Closing Date), (c) on the earliest to occur of (i) the Term Loan Maturity Date, (ii) the date that Borrower prepays the outstanding Secured Obligations relating to the 2017 Term Loan Advance, or (iii) the date that the Secured Obligations relating to the 2017 Term Loan Advance become due and payable, Borrower shall pay Lender the 2017 End of Term Charge (provided that notwithstanding the required payment date of the 2017 End of Term Charge, it shall be deemed earned by Lender as of the Third Amendment Closing Date), and (d) on the earliest to occur of (i) the Term Loan Maturity Date, (ii) the date that Borrower prepays the outstanding Secured Obligations relating to the Optional Term Loan Advance, or (iii) the date that the Secured

Obligations relating to the Optional Term Loan Advance become due and payable, Borrower shall pay Lender the Optional Term Loan End of Term Charge (provided that notwithstanding the required payment date of the Optional Term Loan End of Term Charge, it shall be deemed earned by Lender as of the Third Amendment Closing Date).”

(k) Section 2.7 (Pro Rata Treatment) is amended in its entirety and replaced with the following:

“ 2.7 Pro Rata Treatment. Each payment (including prepayment) on account of any fee and any reduction of the Term Loan Advances, the 2016 Term Loan Advances, the 2017 Term Loan Advance and/or the Optional Term Loan Advance, as applicable, shall be made pro rata according to the Term Commitments of the relevant Lender.”

(l) Section 4.2 (All Advances) is amended by deleting subsection (a) in its entirety and replacing it with the following:

“ (a) Agent shall have received (i) an Advance Request for the relevant Advance as required by Section 2.1(b), Section 2.1.1(b), Section 2.1.1.1(b) or Section 2.1.1.1.1(b), as applicable, duly executed by Borrower’s Chief Executive Officer or Chief Financial Officer, and (ii) any other documents Agent may reasonably request.”

(m) Schedule 1.1 (Commitments) is amended in its entirety and replaced with the Schedule 1.1 appearing as Exhibit A attached hereto.

(n) Exhbit F (Compliance Certificate) is amended in its entirety and replaced with the Compliance Certificate appearing as Exhibit B hereto.
