This Prospectus Supplement relates to the prospectus dated January 24, 2022, as amended and supplemented from time to time (the "Prospectus"), which permits the resale by the selling stockholder listed in the Prospectus of up to 1,578,946 shares of our common stock, par value $0.01 per share ("Common Stock") consisting of an aggregate of 1,052,631 shares of Common Stock and 526,315 shares of Common Stock underlying warrants ("Warrants") issued pursuant to a securities purchase agreement dated December 14, 2021.

We will not receive proceeds from the sale of the shares of Common Stock by the selling stockholder.

Any statement contained in the Prospectus shall be deemed to be modified or superseded to the extent that information in this Prospectus Supplement modifies or supersedes such statement. Any statement that is modified or superseded shall not be deemed to constitute a part of the Prospectus except as modified or superseded by this Prospectus Supplement.
