January 2024 Registration Rights Agreement

 

On January 8, 2024, the Issuer entered into a registration rights agreement (the “January 2024 Registration Rights Agreement”) with the January 2024 PIPE Investors, including the Fund, pursuant to which the Issuer agreed to register for resale the shares of Common Stock issued in the January 2024 Private Placement and the shares of Common Stock issuable upon exercise of the pre-funded warrants issued in the January 2024 Private Placement (collectively, the “January 2024 Registrable Securities”). Under the January 2024 Registration Rights Agreement, the Issuer agreed to file a registration statement covering the resale by the January 2024 PIPE Investors of their January 2024 Registrable Securities no later than 30 days following the closing of the January 2024 Private Placement (the “January 2024 Filing Date”). The Issuer agreed to use commercially reasonable efforts to cause such registration statement to be declared effective by the SEC as soon as reasonably practicable and to keep such registration statement effective until the date all January 2024 Registrable Securities covered by such registration statement have been sold or cease to be registrable securities under the January 2024 Registration Rights Agreement.

 

If (i) the registration statement has not been filed by the January 2024 Filing Date, (ii) the registration statement has not been declared effective by the SEC prior to the earlier of (A) five business days after the date on which the Issuer is notified by the SEC that the registration statement will not be reviewed by the SEC or is not subject to further comment by the SEC, or (B) 15 days after the January 2024 Filing Date (or, in the event the SEC reviews the registration statement, 60 days following the closing of the January 2024 Private Placement) 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 has agreed to make pro rata payments to each holder of January 2024 Registrable Securities as liquidated damages in an amount equal to 1% of the aggregate amount invested by each such holder in the January 2024 Registrable Securities for the initial day of failure and for each subsequent 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 January 2024 Registration Rights Agreement.

 

The Issuer has granted the January 2024 PIPE Investors customary indemnification rights in connection with the registration statement. The January 2024 PIPE Investors have also granted the Issuer customary indemnification rights in connection with the registration statement.

 

References to and the description of the January 2024 Registration Rights Agreement set forth above in this Item 6 do not purport to be complete and are qualified in their entirety by reference to the full text of the January 2024 Registration Rights Agreement, which is attached hereto as Exhibit 3 and incorporated by reference herein.
