Any securities registered hereunder may be sold separately from, or together in the same offering with, other securities registered hereunder. The securities registered also include such indeterminate amounts and numbers of shares of common stock, preferred stock or debt securities that may be issued upon the exercise of warrants registered hereunder or, in the case of common stock and preferred stock, upon the conversion of or in exchange for, or pursuant to the antidilution provisions of, debt securities registered hereunder. Note 1.b. The proposed maximum aggregate offering price per class of security will be determined from time to time by the Registrant in connection with the issuance by the Registrant of the securities registered hereunder and is not specified as to each class of security in reliance on Rule 457(o) under the Securities Act of 1933 and General Instruction II.D of Form S-3 under the Securities Act of 1933. Note 1.c. Each Unit will consist of some or all of the securities listed above, in any combination. Note 1.d.
