ABOUT THIS PROSPECTUS

This prospectus describes the general manner in which the selling stockholders identified in this prospectus may offer, from time to time, shares of our
Common Stock, which may be issued pursuant to the ELOC Purchase Agreement or the Purchase Warrant, as the case may be. We are not selling any securities under this prospectus and will not receive any proceeds from the sale of shares of securities by
the selling stockholders.

This prospectus is part of a registration statement that we filed with the SEC. This prospectus provides you with general
information regarding the securities being offered by the selling stockholders. You should read this prospectus as well as the additional information described under the headings “Information Incorporated by Reference” and “Where You
Can Find More Information” before making an investment decision.

No person has been authorized to give any information or to make any
representations other than those contained in this prospectus in connection with the offering made hereby, and if given or made, such information or representations must not be relied upon as having been authorized by us, the selling stockholders or
by any other person. Neither the delivery of this prospectus nor any sale made hereunder shall, under any circumstances, create any implication that information herein is correct as of any time subsequent to the date hereof. This prospectus does not
constitute an offer to sell or a solicitation of an offer to buy any security other than the securities covered by this prospectus, nor does it constitute an offer to or solicitation of any person in any jurisdiction in which such offer or
solicitation may not lawfully be made.

This document may only be used where it is legal to sell these securities. The information contained in this
prospectus (and in any supplement or amendment to this prospectus) is accurate only as of the date on the front of the document, and any information we have incorporated by reference is accurate only as of the date of the document incorporated by
reference, regardless of the time of delivery of this prospectus or any sale of our securities. Our business, financial condition, results of operations and prospects may have changed since those dates.

References to “selling stockholders” refers to the security holders identified herein in the section titled “Selling Stockholders”
beginning on page [●] of this prospectus, who may sell securities from time to time as described in this prospectus.
