O. Andreas Halvorsen, David C. Ott and Rose S. Shabet (collectively, the “Reporting Persons”).

The business address of each of the Reporting Persons is: 600 Washington Boulevard, Floor 11, Stamford, Connecticut 06901.

VGI is a Delaware limited partnership; Opportunities Parent, Opportunities GP, Opportunities Portfolio GP, VGOD GP, and VGOD Portfolio GP are Delaware limited liability companies; VGOL, VGOP and VGOD are Cayman Islands exempted limited partnerships; O. Andreas Halvorsen is a citizen of Norway; and David C. Ott and Rose S. Shabet are citizens of the United States.

Item 4.

Ownership:

This Statement on Schedule 13G relates to shares of Common Stock held directly by VGOL, VGOP and VGOD, and pre-funded warrants to purchase shares of Common Stock with an exercise price of $0.001 per share (the “Warrants”) held directly by VGOP and VGOD.  VGOL directly owns 1,373,472 shares of Common Stock.  VGOP directly owns 725,489 shares of Common Stock and Warrants with the right to purchase 1,030,856 shares of Common Stock.  VGOD directly owns 357,331 shares of Common Stock and Warrants with the right to purchase 507,735 shares of Common Stock.  However, the terms of the Warrants provide that no holder of Warrants shall have the right to exercise any portion of the Warrants to the extent that, after giving effect to such issuance after exercise, such holder of Warrants (together with its affiliates, any “group” or any other persons whose beneficial ownership could be aggregated with the holders) would beneficially own more than 9.99% of the number of shares of the Common Stock outstanding immediately following exercise (the “Blocker”).  Any holder of Warrants, upon notice to the Issuer, may increase or decrease the Blocker, subject to a maximum of 19.99%, but any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Issuer.  Accordingly, the amount of shares of Common Stock reported as beneficially owned by the Reporting Persons set forth herein excludes shares of Common Stock that the Reporting Persons do not currently have the right to purchase upon exercise of the Warrants held directly by VGOP and VGOD due to the Blocker.  Under the terms of the Blocker, the Blocker applies to the aggregate number of shares of Common Stock that can be purchased upon exercise of the Warrants held by both VGOP and VGOD, and so has been applied pro rata to the Warrants held directly by each of VGOP and VGOD.

The percentages set forth herein are based on (i) 25,268,102 shares of Common Stock outstanding as of December 11, 2023, as reported in the Issuer’s proxy statement on Schedule 14A, filed with the Securities and Exchange Commission (the “Commission”) on December 19, 2023, and (ii) 75,537 shares of Common Stock that the Reporting Persons currently have the right to purchase upon exercise of the Warrants, subject to the Blocker.
