12% Senior Convertible Promissory Note

The Note matures on March 31, 2018 (the “Maturity Date”), less any amounts converted or redeemed prior to the Maturity Date. The Note accrues interest at a rate of 12% per annum, payable on the Maturity Date or upon any conversion, prepayment, event of default or other acceleration of payment under the Note. All interest payments under the Note are payable, at our option, in cash or shares of Common Stock.

All principal and interest due and owing under the Note is convertible into shares of Common Stock at any time at the election of the holder at a conversion price per share equal to the lower of (i) $0.35 or (ii) 75% of the average of the three (3) lowest daily volume weighted-average prices of the Common Stock in the fifteen (15) trading days prior to the conversion date (the “Conversion Price”), which Conversion Price is subject to adjustment for (i) stock splits, stock dividends, combinations, or similar events and (ii) full ratchet anti-dilution protection. Upon certain events of default, the conversion price of the Note will automatically become 70% of the average of the three (3) lowest volume weighted average prices of the Common Stock in the twenty (20) consecutive trading days prior to the conversion date for so long as such event of default remains in effect.

In addition, at any time that (i) the daily volume weighted average price of the Common Stock for the prior ten (10) consecutive trading days is $0.70 or more and (ii) the average daily trading value of the Common Stock is greater than $2,500,000 for the prior ten (10) consecutive trading days, then the Company may demand, upon one (1) day’s notice, that the holder convert the Note at the Conversion Price.

We may prepay in cash any portion of the outstanding principal amount of the Note and any accrued and unpaid interest by, upon ten (10) days’ written notice to the holder, paying an amount equal to (i) 110% of the sum of the then-outstanding principal amount of the Note plus accrued but unpaid interest, if the prepayment date is within 90 days of the issuance date of the Note; (ii) 115% of the sum of the then-outstanding principal amount of the Note plus accrued but unpaid interest, if the prepayment date is between 91 days and 180 days of the issuance date of the Note; or (iii) 125% of the sum of the then-outstanding principal amount of the Note plus accrued but unpaid interest, if the prepayment date is after 180 days of the issuance date of the Note.
