Registration Statement on Form S-1 Filed May 30, 2019 File No. 333-231829 Dear Mr. Erickson: We have limited our review of your registration statement to those issues we have addressed in our comments. In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by amending your registration statement and providing the requested information. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing any amendment to your registration statement and the information you provide in response to these comments, we may have additional comments. Registration Statement on Form S-1 filed May 30, 2019 Fee table, page i 1. We note from footnote 3(v) to your fee table that you are registering for resale an indeterminate number of shares issuable upon conversion of the Series D Convertible Preferred Stock. Please note that you may not rely on Rule 416 to register for resale an indeterminate number of shares that you may issue under a conversion formula. Revise your filing to register for resale the maximum number of shares that you think you may issue upon conversion, based on a good-faith estimate and, if the estimate turns out to be insufficient, the company must file a new registration statement to register the additional shares for resale. For guidance, see the Division of Corporation Finance's Securities Act Rules Compliance and Disclosure Interpretations Question 213.02 which can be found on the Commission's web site. Ronald P.
