 2024, we entered into the RRA with the purchasers party thereto. Pursuant to the RRA, we were obligated to prepare and file a resale registration statement with the SEC within 30 days of July 3, 2024 and to use our reasonable best efforts to cause such registration statement to be declared effective by the SEC within 90 calendar days of July 3, 2024 (or within 120 calendar days of July 3, 2024 if the SEC reviews the registration statement). We also undertook to register the Resale Shares on a registration statement on Form S-3 promptly after such form is available to us. The registration statement of which this prospectus forms a part is intended to continue the satisfaction of these obligations, which were initially satisfied by our filing of a prior registration statement on Form S-1 relating to the resale of such securities, which we intend to terminate upon the effectiveness of this registration statement. Once this registration statement is declared effective, the Resale Shares to which the registration statement relates will no longer constitute restricted securities and may be sold freely in the public markets, subject to lapse on any related contractual restrictions related thereto of any holder party thereto, and subject to any restrictions that may be applicable to any control securities.

We also agreed, among other things, to indemnify the purchasers party thereto and each of their respective officers, directors, agents, partners, members, managers, stockholders, affiliates, investment advisers and employees, each person who controls any such purchaser party and the officers, directors, partners, members, managers, stockholders, agents, investment advisers and employees of each such controlling person from certain liabilities and pay all fees and expenses (excluding any legal fees of the selling holder(s), and any underwriting discounts and selling commissions) incident to our obligations under the RRA.

Securities of a holder cease to be registrable securities under the RRA upon the earlier to occur of the following: (A) a sale pursuant to a registration statement or Rule 144 under the Securities Act; and (B) the time such shares become eligible for resale by such holder under Rule 144 without the requirement for the Company to be in compliance with the current public information required by Rule 144(c) and Rule 144(i)(2) and without
