During the Term of this Agreement, subject to the terms and conditions below, BACH grants to POINT a Right of First Negotiation (“ROFN”) to [***] (which are not FAPi Radiopharmaceuticals Inventions, FAPi- targeted [***] Inventions or [***] Agent Inventions subject to Exclusive Commercialization Option above) owned or controlled by BACH. Accordingly, before entering into any transaction pertaining to a [***] (a “[***] Transaction”) with any third party, BACH shall first notify POINT in writing (“ROFN Notice”) of the potential [***] Transaction, which notice shall include sufficient written detail of the proposed [***] as available to BACH and reasonably necessary for

If POINT elects to pursue such [***] Transaction, it shall deliver written notice to BACH within such [***]-day period, and the Parties will proceed to negotiate and finalize definitive agreements. 3.11 Future Inventions. For any invention involving a FAPi Radiopharmaceuticals Invention, FAPi-targeted [***] Invention or [***] Agent Invention made solely or jointly by [***] after the Effective Date of the Amendment, in the instance that BACH does not fully own or control the patent rights to that invention, then upon POINT’s exercise of the Exclusive Commercialization Option to BACH’s rights in the invention or notice from BACH that such invention is not owned or controlled by BACH in any fashion, at POINT’s election BACH and [***] each shall exercise best efforts (without incurring more than $[***] in expenses to BACH) to i) assist POINT in obtaining exclusive control (such as by additional licensing) of such invention from any other co-inventors or co-owners or ii) for BACH to obtain rights to such invention in a manner whereby the invention can be subject to the Exclusive Commercialization Option.
