| Item 4. | OWNERSHIP: |
| The information required by Items 4(a) - (c) is set forth in Rows 5 - 11 of the cover page for each of the Reporting Persons and is incorporated herein by reference. | |
| The percentages set forth herein are calculated based upon 33,483,111 Shares outstanding as of November 13, 2023 as reported in the Company's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2023, filed with the Securities and Exchange Commission on November 13, 2023, and assumes the exercise or conversion of the Securities (as defined below) held by the RTW Funds, subject to the 9.99% Blocker (as defined below). |
| CUSIP No. 59935V107 | 13G/A | Page 6 of 7 Pages |
| Pursuant to the terms of certain warrants and convertible notes (collectively, the “Securities”), the RTW Funds cannot exercise or convert such Securities if the Reporting Persons would beneficially own, after such exercise or conversion, more than 9.99% of the outstanding Shares (the "9.99% Blocker"). The percentage set forth on Row (11) and the number of shares of Common Stock set forth on rows (6), (8) and (9) of the cover page for each Reporting Person give effect to the 9.99% Blocker. Consequently, at this time, the Reporting Persons are not able to convert all the Securities held by the RTW Funds due to the 9.99% Blocker. |
| Item 5. | OWNERSHIP OF FIVE PERCENT OR LESS OF A CLASS: |
| Not applicable. |
| Item 6. | OWNERSHIP OF MORE THAN FIVE PERCENT ON BEHALF OF ANOTHER PERSON: |
| See Item 2. The RTW Funds have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares reported herein.
