The Convertible Debentures are not redeemable prior to the Maturity Date; provided, however, that, if the Company has not executed the security documents relating to the security being provided in connection with the offering within 90 days from the closing date, the Company shall be obligated to repurchase the Convertible Debentures, by the date that is 120 days from the closing date, at a price equal to 100% of the principal amount of the Convertible Debentures then outstanding plus any accrued and unpaid interest thereon up to and including the date of redemption.
