| Item 6. | Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer | |
Each of SR One Fund I Aggregator, SR One Opportunities Fund I, and SR One Co-Invest is party to the Third Amended and Restated Investors' Rights Agreement, dated August 2, 2023, with the Issuer and certain other stockholders (the "Investors' Rights Agreement"). The Investors' Rights Agreement grants the parties thereto, including the Funds referenced above, certain registration rights in respect of registrable securities. The registration of shares of the Issuer's Common Stock pursuant to the exercise of these registration rights will enable the holders thereof to sell such shares without restriction under the Securities Act when the applicable registration statement is declared effective. Under the Investors' Rights Agreement, the Issuer will pay all registration expenses and the holders will pay all selling expenses, including underwriting discounts and selling commissions, relating to the sale of their shares. The Investors' Rights Agreement also includes customary cross indemnification and procedural terms. These registration rights will terminate upon the earliest of (i) the closing of a "Deemed Liquidation Event," as such term is defined in the Issuer's certificate of incorporation as in effect prior to the IPO, (ii) with respect to any particular holder, such date on or after the Closing on which all registrable securities held by such holder may immediately be sold during any three-month period pursuant to Rule 144 under the Securities Act or another similar exemption and (iii) the fifth anniversary of the Closing.
The Investors' Rights Agreement provides that at any time beginning 180 days after September 24, 2026, the holders of at least 30% of the registrable securities then outstanding may request that the Issuer register shares on a registration statement on Form S-1, provided that such request for registration covers at least 40% of the registrable securities then outstanding with an anticipated aggregate offering price in excess of $15.0 million, net of expenses, and provided further that the Issuer will not be required to effect such a registration if, among other things, it has already effected one such registration. Once the Issuer is eligible to use a registration statement on Form S-3, the holders of registrable securities may request that the Issuer register all or a part of their registrable securities on Form S-3 if the anticipated aggregate offering price is at least $5.0 million, net of expenses, provided that the Issuer will not be required to effect such a registration if, among other things, it has already effected two such registrations within the preceding 12 months.
Further, the Investors' Rights Agreement provides that in the event the Issuer proposes to register any of its Common Stock under the Securities Act, either for its own account or for the account of other security holders, the holders of registrable securities will be entitled to notice of the registration and to "piggyback" registration rights allowing such holders to include their shares in such registration, subject to certain conditions and limitations, including the right of the underwriters to limit the number of shares included in such registration.
In addition, each of SR One Fund I Aggregator, SR One Opportunities Fund I, and SR One Co-Invest 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 J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, on behalf of the underwriters, for a period of 180 days after September 24, 2026, it will not, and will not cause any direct or indirect affiliate to, (i) 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, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the Fund in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant), (ii) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of any such securities, whether any such transaction described in clauses (i) or (ii) is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, (iii) make any demand for or exercise any right with respect to the registration of any such securities or (iv) publicly disclose the intention to do any of the foregoing. | ||

As attorney-in-fact
This Agreement relating to Schedule 13D was executed by Sasha Keough on behalf of the individuals listed above pursuant to a Power of Attorney, a copy of which is attached hereto as Exhibit 2.
EXHIBIT 2
LIMITED POWER OF ATTORNEY
Know all by these presents, that the undersigned hereby makes, constitutes and appoints Sasha Keough, Karen Narolewski-Engel, James Macadam, and Alexander M. Bowling, and each of them singly, as each of the undersigned’s true and lawful attorneys-in-fact with full power and authority as hereinafter described to:
1. execute for and on behalf of each of the undersigned individual and entities (each, a “Filer” and collectively, the “Filers”) (i) Forms 3, 4, and 5 (including amendments thereto) in accordance with Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules thereunder, (ii) Form 144 in accordance with Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), and (iii) Schedules 13D and 13G (including amendments thereto) in accordance with Sections 13(d) and 13(g) of the Exchange Act and the rules thereunder;
2. do and perform any and all acts for and on behalf of each of the Filers which may be necessary or desirable to complete and execute any such Form 3, 4, or 5 (including amendments thereto), Form 144, or Schedule 13D or 13G (including amendments thereto) and timely file such form with the United States Securities and Exchange Commission (the “SEC”) and any stock exchange or similar authority, including, but not limited to, executing a Form ID or Update Passphrase request for and on behalf of each of the undersigned and filing such applications with the SEC; and
3. take any other action of any type whatsoever in connection with the foregoing which, in the opinion of such attorney-in-fact, may be of benefit to, in the best interest of, or legally required by, a Filer, it being understood that the documents executed by such attorney-in-fact on behalf of such Filer pursuant to this Limited Power of Attorney shall be in such form and shall contain such terms and conditions as such attorney-in-fact may approve in such attorney-in-fact’s discretion.
Each of the Filers hereby grants to each attorney-in-fact full power and authority to do and perform any and every act and thing whatsoever requisite, necessary, or proper to be done in the exercise of any of the rights and powers herein granted, as fully to all intents and purposes a Filer might or could do if personally present, with full power of substitution or revocation, hereby ratifying and confirming all the acts such attorney-in-fact, or such attorney-in-fact’s substitute or substitutes, shall lawfully do or cause to be done by virtue of this Limited Power of Attorney and the rights and powers herein granted. Each of the Filers acknowledges that each of the foregoing attorneys-in-fact, in serving in such capacity at the request of such Filer, is not assuming any of such Filer’s responsibilities to comply with Sections 13 or 16 of the Exchange Act or Rule 144 under the Securities Act.
This Limited Power of Attorney shall remain in full force and effect until a Filer is no longer required to file Forms 3, 4, and 5 (including amendments thereto), Form 144, and Schedules 13D and 13G (including amendments thereto) with respect to such Filer’s holdings of and transactions in securities, unless earlier revoked by such Filer in a signed writing delivered to each of the foregoing attorneys-in-fact. In addition, at such time as any attorney-in-fact resigns as attorney-in-fact by the execution of a written resignation delivered to each Filer, without any action on the part of the Filers, this Limited Power of Attorney shall be partially revoked solely with respect to such individual; such individual shall cease to be an attorney-in-fact under this Limited Power of Attorney; and the authority of the other attorneys-in-fact then existing hereunder shall remain in full force and effect.
[Signature page follows]
IN WITNESS WHEREOF, each of the undersigned has caused this Limited Power of Attorney to be executed as of this 12th day of December, 2022.
