Exchange of Stock Certificates
If the reverse stock split proposal is effected, shareholders holding certificated shares (i.e. shares represented by one or more physical stock certificates) will be required to exchange their existing certificates (Old Certificate(s)) for new certificate(s) representing the appropriate number of shares of our common stock resulting from the reverse stock split (New Certificates). Shareholders of record upon the effective time of the reverse stock split proposal will be furnished the necessary materials and instructions for the surrender and exchange of their Old Certificate(s) at the appropriate time by our transfer agent. Shareholders will not have to pay any transfer fee or other fee in connection with such exchange. As soon as practicable after the effective time, our transfer agent will send a transmittal letter to each shareholder advising such holder of the procedure for surrendering Old Certificate(s) in exchange for New Certificate(s).
