As part of the April 2015 Note, at our option, subject to certain volume, price and other conditions, the monthly installments of principle and interest due under the April 2015 Note may be paid in whole, or in part, in cash or in Common Stock. If the monthly installments are paid in Common Stock, such shares being issued will be based on a price that is 80% of the average of the three lowest volume weighted average prices of the shares of Common Stock during the preceding twenty trading days. The percentage declines to 70% if the average of the three lowest volume weighted average prices of the shares of Common Stock during the preceding twenty trading days is less than $0.05 per share. For the purposes of this Table, we have assumed that all outstanding monthly installments of principal and interest will be paid in Common Stock based on a price of $0.06 per share (80% of the average of the three lowest volume weighted average prices of the shares of Common Stock during the preceding twenty trading days prior to March 31, 2016), subject to certain ownership limitations.
