Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

 

Item 6 of the Statement is hereby amended and supplemented as follows:

 

Registration Rights Agreement

 

The Reporting Persons, together with the other investors in the 2020 Private Placement, entered into a registration rights agreement with the Issuer on December 10, 2020 (the “2020 Registration Rights Agreement”), which provides certain rights with respect to the registration of the shares of Common Stock acquired in the 2020 Private Placement.

 

Pursuant to the 2020 Registration Rights Agreement, the Issuer has agreed to file a registration statement covering the resale of the shares acquired in the 2020 Private Placement within the earlier of either (A) the later of (x) 30 days after the closing date of the 2020 Private Placement or (y) 15 days after the Issuer discloses any material non-public information that the Issuer may have provided the investors in connection with the 2020 Private Placement or (B) 120 days following the closing date of the 2020 Private Placement (the “Filing Deadline”). The Issuer has agreed to use commercially reasonable efforts to cause such registration statement to be declared effective as soon as practicable and to keep such registration statement effective until the date the shares of Common Stock covered by such registration statement have been sold or cease to be registrable securities (“2020 Registrable Securities”) under the 2020 Registration Rights Agreement.

 

In the event that (i) the registration statement has not been filed by the Filing Deadline, (ii) the registration statement is not declared effective prior to the earlier of (a) five business days after the date on which the Issuer is notified by the Securities and Exchange Commission (the “SEC”) that the registration statement will not be reviewed by the SEC staff or is not subject to further comment by the SEC staff or (b) the 15th day after the Filing Deadline (or the 60th day after the Filing Deadline if the SEC staff determines to review the registration statement), or (iii) after the registration statement has been declared effective by the SEC, sales cannot be made pursuant to the registration statement for any reason, subject to certain limited exceptions, then the Issuer agreed to make pro rata payments to each of the investors in the 2020 Private Placement then holding 2020 Registrable Securities as liquidated damages in an amount equal to 1% of the aggregate amount invested by each such investor in the 2020 Private Placement per 30-day period or pro rata for any portion thereof for each such month during which such event continues, subject to certain caps set forth in the 2020 Registration Rights Agreement.

 

 

 

CUSIP No. 83422E105

 

The Issuer is responsible for all fees and expenses incurred in connection with the registration of the 2020 Registrable Securities. The Issuer granted customary indemnification rights in connection with the registration statement. The investors have also granted the Issuer customary indemnification rights in connection with the registration statement.

 

References to and the description of the 2020 Registration Rights Agreement set forth in this Item 6 do not purport to be complete and are qualified in their entirety by reference to the full text of the 2020 Registration Rights Agreement, which is attached hereto as Exhibit 4 and incorporated by reference herein.
