Subject to earlier repayment as provided in Section 2 below, the outstanding principal amount of this Note, along with any and all accrued but unpaid interest hereunder, shall become due and payable on the earliest to occur of (i) December 31, 2017 (the “Maturity Date”), or (ii) an Event of Default (as defined in Section 2 below). All payments hereunder, whether for principal, interest or otherwise shall be made in immediately available United States funds sent to the Payee at the address set forth on the signature page hereto or such other address furnished in writing to the Company for that purpose or by wire-transfer to an account specified in writing by Payee. Interest hereunder shall accrue on the outstanding principal amount of this Note from the date hereof until the repayment in full of the principal amount hereunder and the payment of all accrued but unpaid interest hereunder.
