Item 4. Ownership.

Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a) Amount beneficially owned:

328,156 shares of Common Stock, consisting of (1) 240,000 shares held directly (including 40,000 shares held by Carl I. Schwartz Revocable Family Trust); (2) 49,321 shares issuable upon conversion of 266.67 shares of Series E Preferred Stock as of September 30, 2020; and (3) 38,835 shares that may be purchased pursuant to outstanding stock purchase warrants issued on January 28, 2020 (the “2020 Warrants”), which do not include a limitation on beneficial ownership.

The reporting person holds additional warrants to purchase 57,500 shares (the “Blocker Warrants”), all of which include a provision to the effect that the reporting person, with certain exceptions, may not exercise the warrants if after such exercise the reporting person would beneficially own more than 4.99% of the outstanding Common Stock of the Issuer. As of December 31, 2020, the reporting person would not have been entitled to exercise the Blocker Warrants because of these limitations.

(b) Percent of class:

5.54% as of December 31, 2020.

(Based upon the Issuer’s Form 10-Q filed on October 22, 2020, the Issuer had 5,833,245 shares outstanding as of October 21, 2020.)

Explanatory Note: The reporting person’s percentage beneficial ownership set forth above is based on the most recent available information as of December 31, 2020. As reported in its Form 8-K report filed on January 12, 2021 and its prospectus supplement dated January 11, 2021, on January 12, 2021 the Issuer had approximately 7.7 million shares outstanding. Based on such outstanding shares, the reporting person’s beneficial ownership as of January 12, 2021 was less than 5%. As a result, the reporting person has checked the box in Item 5 reporting that he no longer is the beneficial owner of more than 5 percent of the common stock.

Carl I. Schwartz has sole voting and dispositive power over 328,156 shares of Common Stock.

Item 5. Ownership of Five Percent or Less of a Class.

If this statement is being filed to report the fact that as of the date hereof the reporting person has ceased to the beneficial owner of more than 5 percent of the class of securities, check the following (see Explanatory Note in Item 4(b)): x
