Description of debt conversion

The 2014/2015 Convertible Notes could not be repaid prior to their maturity date without the consent of the holders of at least a majority of the outstanding principal amount of the 2014/2015 Convertible Notes. The 2014/2015 Convertible Notes contained two conversion options contingent upon the occurrence of a future event, as follows: (i) all outstanding principal and unpaid accrued interest on the 2014/2015 Convertible Notes would automatically convert into equity securities upon the consummation of an equity financing with proceeds of at least $2 million (“Qualified Financing”) at conversion rates of 70% or 80%, as noted below; and (ii) if the Company was acquired, prior to a Qualified Financing, in a change in control transaction, the holder had an option to have all outstanding principal plus any unpaid accrued interest paid in cash or convert such amount into shares of common stock at a conversion price equal to $7.50 per share, subject to adjustment for such events as stock splits, combination, and reorganization.
