CUSIP No. 63911H108

**Introductory Note**: This Amendment No. 1 (the "Amendment") amends and supplements the Schedule 13D originally filed by the Reporting Persons with the Commission on September 19, 2022 (the "Original Schedule 13D"). This Amendment is being filed to update the aggregate percentage of the Issuer's Common Stock owned by the Reporting Persons due to dilution caused by the Issuer's sales of additional shares of its Common Stock from time to time since the date of the filing of the Original Schedule 13D and not in connection with a disposition of any shares by the Reporting Persons. Such dilution resulted in a decrease of over one percent (1%) in the aggregate percentage ownership reported by the Reporting Persons in the Original Schedule 13D. Only those items that are hereby reported are amended; all other items reported in the Original Schedule 13D remain unchanged. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable. Capitalized terms not defined in this Amendment have the meanings ascribed to them in the Original Schedule 13D.

**Item 5. Interest in Securities of the Issuer.** 

(a) and (b) See Items 7-11 of the cover pages of this Amendment and Item 2 above. The aggregate number of shares of the Issuer owned by the Reporting Persons, and the percentage of the class of securities identified pursuant to Item 1 is calculated based on 47,250,771 shares of Common Stock outstanding as of November 14, 2022, as reported in the Form 10-Q, plus 408,160 shares of Common Stock issuable upon conversion of the Private Warrants and 408,160 shares of Common Stock issuable upon conversion of the Debentures.

(c) Except as reported in this Amendment, none of the Reporting Persons has effected any transactions in the Issuer's securities within the past 60 days.

(d) Under certain circumstances set forth in the limited partnership agreement of MIF II, the general partner and limited partners of MIF II may be deemed to have the right to receive dividends from, or the proceeds from, the sale of shares of the Issuer owned by MIF II.

(e) Not applicable.

------

**SIGNATURE** 

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
