This Schedule 13D/A No. 5 supplements Item 3 of the Original Schedule 13D by adding the following:

Source of Mr. Stachowiak’s Shares. The Common Shares reported as beneficially owned by the Reporting Person include the Common Shares acquired in the transactions described below that occurred since Mr. Stachowiak’s reporting of beneficial ownership in the Schedule 13D/A No. 4.

● On June 3, 2021, Mr. Stachowiak acquired 2,000 Common Shares upon his exercise of 2,000 stock options (such underlying Common Shares, “Option Shares”), at an exercise price of $2.43 per share, all of which became exercisable on June 9, 2015 and were set to expire on June 9, 2021.

● On July 1, 2021, Mr. Stachowiak was granted an award of 60,000 restricted stock units (“RSUs”), each entitling Mr. Stachowiak to one share of Common Stock upon vesting. On December 31, 2021, the 60,000 RSUs vested in full.

● On January 3, 2022, Mr. Stachowiak was granted an award of 120,000 RSUs, which vested in equal quarterly installments on March 31, 2022, June 30, 2022, September 30, 2022, and December 31, 2022.

● On May 31, 2022, Mr. Stachowiak acquired 2,000 Option Shares upon his exercise of 2,000 stock options at an exercise price of $2.70 per share, all of which became exercisable on June 15, 2016 and were set to expire on June 15, 2022.

For purposes of this Schedule 13D/A No. 5, only 60,000 Common Shares underlying 120,000 of the RSUs are reported as being beneficially owned by Mr. Stachowiak. The remaining 60,000 RSUs and underlying Common Shares granted to Mr. Stachowiak on March 28, 2023 are excluded from Mr. Stachowiak’s reported beneficial ownership because they will not vest within 60 days of the filing date of this Schedule 13D/A No. 5 (the “Filing Date”).

All of the Common Shares reported herein were received by Mr. Stachowiak in connection with his services as the Issuer’s Chief Executive Officer from October 1, 2020 to March 7, 2023 and Executive Chairman of the Issuer’s Board, a position he was appointed to on March 7, 2023.

Source of Shares of RCS. All of the shares reported as beneficially owned by RCS were acquired through purchases of shares and warrants exercisable for shares using RCS funds.

Item 4. Purpose of Transaction.

This Schedule 13D/A No. 5 amends and restates Item 4 of the Original Schedule 13D as follows:

The information reported in Item 3 of this Schedule 13D/A No. 5 is incorporated by reference into this Item 4. The Common Shares reported as beneficially owned by the Reporting Persons will be held for investment purposes.

Before Mr. Stachowiak became an officer and director of the Issuer, the securities acquired by Mr. Stachowiak were primarily acquired through purchases using his personal funds. After Mr. Stachowiak became an officer of the Issuer, Mr. Stachowiak acquired Common Shares from the Issuer as partial compensation for his service as an officer, including for his former officer roles as Interim President and Chief Executive Officer and for his current officer role as Executive Chairman.

Mr. Stachowiak is a director and the Executive Chairman of the Issuer, the owner-president of RCS, and the owner-manager of Stachowiak Equity. Except as set forth herein and to the extent that Mr. Stachowiak may have influence over the corporate activities of the Issuer, including activities that may relate to the items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, the Reporting Persons do not have any present plan or proposal that relate to or would result in any of the matters set forth in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

The Reporting Persons reserve the right to increase or decrease their position in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions or otherwise on such terms and at such times as the Reporting Persons may deem advisable. The Reporting Persons reserve the right to change their intention with respect to any and all matters referred to in this Item 4.

Item 5. Interest in Securities of the Issuer.

This Schedule 13D/A No. 5 amends and restates Item 5 of the Original Schedule 13D as follows:

(a)   The table below reports the aggregate number of Common Shares beneficially owned by each Reporting Person, the total issued and outstanding Common Shares ( the “Total I&O Amount”) used to calculate each Reporting Person’s percentage of beneficial ownership in accordance with the SEC rules for calculating percentages of beneficial ownership, and each Reporting Person’s percentage of beneficial ownership as of the Filing Date of this Schedule 13D/A No. 5.

Each Reporting Person expressly disclaims beneficial ownership of all of the Common Shares reported in this Schedule 13D/A No. 5 except to the extent of such Reporting Person’s pecuniary interest therein, and the filing of this Schedule 13D/A No. 5 shall not be construed as an admission that any such Reporting Person is, for purposes of Sections 13(d) or 13(g) of the Exchange Act, the beneficial owner of any securities covered by this Schedule 13D/A No. 5.
