GENERATE BIOMEDICINES, INC.
2026 EMPLOYEE STOCK PURCHASE PLAN
The purpose of the Generate Biomedicines, Inc. 2026 Employee Stock Purchase Plan (the “Plan”) is to provide eligible employees of Generate Biomedicines, Inc. (the “Company”) and each Designated Company (as defined in Section 11) with opportunities to purchase shares of Stock (as defined in Section 11). An aggregate of 1,481,589 shares of Stock have been approved and reserved for this purpose plus, on January 1, 2027 and each January 1 thereafter through January 1, 2036, the number of shares of Stock reserved and available for issuance under the Plan shall be cumulatively increased by the least of (i) 1% of the number of Outstanding Shares on the immediately preceding December 31st, (ii) 2,963,178 shares of Stock or (iii) such number of shares of Stock as determined by the Administrator.
The Plan includes two components: a Code Section 423 Component (the “423 Component”) and a non-Code Section 423 Component (the “Non-423 Component”). It is intended for the 423 Component to constitute an “employee stock purchase plan” within the meaning of Section 423(b) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the 423 Component shall be interpreted in accordance with that intent (although the Company makes no undertaking or representation to maintain such qualification). In addition, this Plan authorizes the grant of Options (as defined in Section 8) under the Non-423 Component, which does not qualify as an “employee stock purchase plan” under Section 423 of the Code, and such Options granted under the Non-423 Component shall be granted pursuant to separate Offerings (as defined in Section 2) containing such sub-plans, appendices, rules or procedures as may be adopted by the Administrator (as defined in Section 1) and designed to achieve tax, securities laws or other objectives for eligible employees and the Designated Companies in locations outside of the United States. Except as otherwise provided herein or by the Administrator, the Non-423 Component will operate and be administered in the same manner as the 423 Component.
For purposes of this Plan, the Administrator may designate separate Offerings under the Plan, the terms of which need not be identical, in which eligible employees will participate, even if the dates of the applicable Offerings are identical, provided that the terms of participation are the same within each separate Offering under the 423 Component as determined under Section 423 of the Code. Solely by way of example and without limiting the foregoing, the Company could, but is not required to, provide for simultaneous Offerings under the Section 423 Component and the Non-423 Component of the Plan.
1. Administration. The Plan will be administered by the person or persons (the “Administrator”) appointed by the Company’s Board of Directors (the “Board”) for such purpose. The Administrator has authority at any time to: (i) adopt, alter and repeal such rules, guidelines and practices for the administration of the Plan and for its own acts and proceedings as it deems advisable; (ii) interpret the terms and provisions of the Plan; (iii) determine when and how Options will be granted and the provisions and terms of each Offering and/or Purchase Period (as defined in Sectio 11) (which need not be identical); (iv) select Designated Companies; (v) impose a mandatory holding period pursuant to which Participants (as defined in Section 11) may not dispose of or transfer shares of Stock purchased under the Plan for a period of time determined by the Administrator in its discretion; (vi) make all determinations it deems advisable
