(b)

up to the sum of the following (collectively, the ‘September 16-30 Combined Non-Budgeted Expenses’): (i) $500,000 for Borrower’s Payroll Expenses incurred and paid

Exhibit 10.2

during the period of September 16 through September 30, 2016 (the ‘September 16-30 Payroll Expenses’) and Borrower’s Non-Budgeted Non-Payroll Expenses incurred and paid during the period of September 16 through September 30, 2016, plus (ii) the difference between $500,000 and the amount of September 1-15 Combined Non-Budgeted Expenses actually incurred and paid; and

(c)

up to $500,000 for Budgeted Non-Payroll Expenses paid during the period of September 16 through September 30, 2016.

Notwithstanding the foregoing, upon the Bank transmitting to Creditor and copying to Borrower, by e-mail which shall be deemed received by Creditor and Borrower when transmitted by Bank, a written notice of Bank's termination of its payment obligations hereunder, which Bank may send in its sole and absolute discretion, Bank shall only be obligated to pay (i) New Lender Indebtedness properly incurred pursuant hereto prior to Creditor's receipt of such notice, and (ii) any September 16-30 Payroll Expenses incurred during the three Business Days following the giving of such notice.”

is hereby amended to read:

(a)

$1,200,000; plus

(b)

the amount of October 2016 New Lender Indebtedness outstanding, if any.”

2. General. The parties hereto hereby ratify and confirm the continuing validity, enforceability and effectiveness of the Subordination Agreement, and all terms and provisions thereof, as amended herein.
