To the extent the Company is not permitted by applicable NYSE MKT rules to issue any additional shares of Common Stock that would otherwise be required to be issued pursuant to the terms of the Agreement as a result of a dilutive financing, the Company has agreed to pay the Holders a cash payment equal to the difference between the price per share in such dilutive financing and $4.05 for each share issued to the Holders pursuant to the Conversion.
