indicating that the shares of common stock and warrants are only

To the extent you are offering the common shares and warrants

register them as Units in your offering, even if the common stock and
                                                        warrants are
immediately separable following the offering. If you plan to offer Units,

the offering, identifying the components of the Units. For guidance,
                                                        please refer to
