If the VWAP of the Issuer's common stock has been at least $9.75 (subject to adjustment) for at least 20 trading days during any 30 consecutive trading day period, the Issuer may force the conversion of all or any part of the outstanding principal amount of the Debentures, accrued and unpaid interest and any other amounts then owing, subject to certain conditions.
