Amended and Restated Technology Services Agreement
On November 11, 2020, Legacy Quantum-Si entered into an Amended and Restated Technology Services Agreement (the “ARTSA”) by and among 4Catalyzer, Legacy Quantum-Si and other participant companies controlled by the Rothbergs, including Butterfly Network, Inc., AI Therapeutics, Inc., Hyperfine, Inc., 4Bionics LLC, Tesseract Health, Inc., Liminal Sciences, Inc. and Homodeus Inc. Under the ARTSA, Legacy Quantum-Si and the other participant companies agreed to share certain non-core technologies, which means any technologies, information or equipment owned or otherwise controlled by the participant company that are not specifically related to the core business area of the participant, such as software, hardware, electronics, fabrication and supplier information, vendor lists and contractor lists, subject to certain restrictions on use, with the other participant companies. The ARTSA provides that ownership of each non-core technology shared by 4Catalyzer, Legacy Quantum-Si or another participant company will remain with the company that originally shared the non-core technology. The ARTSA also provides for 4Catalyzer to perform certain services to Legacy Quantum-Si and each other participant company, such as general administration, facilities, information technology, financing, legal, human resources and other services. The ARTSA also provides for the participant companies to provide other services to each other. The fees due to 4Catalyzer or the other participants for such services are allocated to Legacy Quantum-Si and the participant companies based on the total costs and expenses for the relative amount of services and resources used by the participant company, except for services with respect to intellectual property, which are based on a negotiated cost plus methodology. The ARTSA provides that all inventions of 4Catalyzer, Legacy Quantum-Si or the other participants made in the course of providing such services will be owned by the receiving participant and that the receiving participant will grant to the participant company providing the services a royalty-free, perpetual, limited, worldwide, non-exclusive license to use such inventions only in the core business field of the participating company.
The ARTSA has an initial term of five years from the date of the ARTSA and provides that the ARTSA will be automatically extended for additional, consecutive one-year renewal terms. Each participating company, including Legacy Quantum-Si, has the right to terminate the ARTSA at any time upon 30 days’ prior notice and 4Catalyzer has the right to terminate the ARTSA at any time upon 90 days’ prior notice. Legacy Quantum-Si paid an aggregate of $2,546,732, $2,213,612 and $1,516,224 during the years ended December 31, 2018, 2019, and 2020, respectively, and $712,172 since January 1, 2021 for services under the ARTSA.
On February 17, 2021, Legacy Quantum-Si and 4Catalyzer entered into the First Addendum to the ARTSA, pursuant to which Legacy Quantum-Si agreed to terminate its participation under the ARTSA no later than immediately prior to the Effective Time. Legacy Quantum-Si entered into a Master Services Agreement with 4Catalyzer effective as of February 17, 2021 pursuant to which Legacy Quantum-Si may engage 4Catalyzer to provide services such as general administration, facilities, information technology, financing, legal, human resources and other services, through future statements of work and under terms and conditions to be determined by the parties with respect to any services to be provided.
