On May 30, 2025, each Fund and certain other stockholders of the Issuer entered into an Amended and Restated Investors' Rights Agreement (the "Investors' Rights Agreement") with the Issuer. Upon the Closing, the Investors' Rights Agreement entitles the parties thereto, including the Funds, to certain demand registration rights. Subject to certain conditions and limitations, at any time beginning 180 days after the effective date of the registration statement of the IPO, the holders of at least a majority of the shares having registration rights then outstanding can request that the Issuer file a registration statement on Form S-1 to register the offer and sale of their shares so long as the request covers securities the anticipated aggregate public offering price of which is at least $10 million. Further, upon the Closing, the Investors' Rights Agreement entitles the parties thereto, including the Funds, to certain Form S-3 registration rights. Subject to certain conditions and limitations, at any time when the Issuer is eligible to file a registration statement on Form S-3, the holders of at least 25% of the shares having these registration rights then outstanding can request that the Issuer register the offer and sale of their shares of Common Stock on a registration statement on Form S-3 so long as the request covers securities the anticipated aggregate public offering price of which, net of certain selling expenses, is at least $1 million. In addition, upon the Closing, the Investors' Rights Agreement entitles the parties thereto, including the Funds, to certain "piggyback" registration rights. If the Issuer proposes to register the offer and sale of its Common Stock under the Securities Act of 1933, as amended (the "Securities Act"), all holders of such shares then outstanding can request that the Issuer include their shares in such registration, subject to certain marketing and other limitations, including the right of the underwriters to limit the number of shares included in any such registration statement under certain circumstances. As a result, whenever the Issuer proposes to file a registration statement under the Securities Act, other than with respect to (1) a registration relating to any employee benefit, incentive or similar plan, (2) a registration relating to a transaction covered by Rule 145 promulgated under the Securities Act, (3) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the registrable securities or (4) a registration in which the only stock being registered is Common stock issuable upon conversion of debt securities also being registered, the holders of such shares are entitled to notice of the registration and have the right, subject to certain limitations, to include their shares in the registration. The Issuer will pay the registration expenses (other than underwriting discounts, selling commissions and stock transfer taxes) of the holders of the shares to be offered and sold pursuant to the registrations described above, including the reasonable fees and disbursements of one counsel chosen by the holders of the shares included in such registrations. In addition, each Fund entered into a lock-up agreement in connection with the IPO whereby each Fund has agreed, subject to certain exceptions, that without the prior written consent of Jefferies LLC and Leerink Partners LLC, that for a period of 180 days after February 5, 2026, it will not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer, any shares of Common Stock or any securities convertible into, exercisable for or exchangeable for shares of Common Stock, or enter into any swap or other arrangement that transfers to another, in whole or in part, directly or indirectly, any of the economic consequences of ownership of the Common Stock. In addition, each Fund entered into a market standoff agreement with the Issuer whereby each Fund has agreed, subject to certain exceptions, that for a period of up to 180 days after February 5, 2026, it will not, without the prior written consent of the managing underwriter, lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or hedge, any shares or any securities convertible into or exchangeable for shares of Common Stock.
