Page 3 of 6 Party, and their respective past, present and future owners, directors, officers, associates, agents, representatives, predecessors, parent companies, affiliates, subsidiaries, related entities, trustees, managers, administrators, employees, attorneys, insurers, re-insurers, members, members of members, joint-venturers, lenders, predecessors, successors and assigns, from and against any and all past, present and future liabilities, claims, demands, compensation, damages, controversies, obligations, administrative complaints, causes of action and suits, whether based in tort, contract, statute, common law, or any other type of legal or equitable theory which could be asserted in any state court, federal court, arbitration or any other legal or administrative proceeding, including, without limitation, for actual, compensatory, consequential, incidental, liquidated or punitive damages, tort and/or contract damage, liabilities, costs, expenses, attorneys' fees, expert fees, investigation fees, and obligations of every possible kind and nature, known or unknown, fixed or contingent, joint or several, whether at law or in equity, suspected or unsuspected, which now exist or may later accrue, arising from and/or related in any way to, the Lease, the Premises, the Building, and the claims and counterclaims that were made in or could have been made in the Action or any subsequent cause of action. This release shall constitute a full general release. The Parties hereby waive the benefits of any law of Connecticut or any other state of the United States which provides that a general release does not extend to claims which the party does not know or expect to exist in its favor at the time of executing the release, which if known to him or her may have materially affected the settlement. It is the intention of the Parties to forever discharge and release all known and unknown claims and potential claims falling within the scope of Section 5 above. 6. Confidentiality. The Parties and their attorneys agree that the terms of this Agreement, and the reasons for entering the same, are confidential and shall not be discussed with any third parties, except as expressly provided herein. The Parties further agree that they may disclose the Agreement and the terms of this Agreement (1) to their attorneys, accountants, lenders, financial advisors, insurers, members, officers, directors, employees, and agents, but only to the extent necessary and with the prior express instruction that the terms shall be kept confidential; (2) in response to an order of a court of competent jurisdiction or subpoena issued under the authority thereof; (3) in response to an inquiry or subpoena issued by a state or federal governmental agency; (4) to publicly state in response to an inquiry that the claim has been resolved to the parties' satisfaction and that Quantum-Si Incorporated is no longer a tenant of the Building; (5) to government employees as required by law; (6) if they reasonably determine that disclosure is necessary or appropriate under any applicable laws or regulations, including pertaining to financial reporting, and (7) the Parties agree that Tenant may disclose to the Securities and Exchange Commission (the "SEC") on a form 8-K, 10-Q , 10-K, or as otherwise required or directed, the amount of the Settlement Payment, that this Action has been resolved and any other information relating to this Agreement which Tenant deems to be required, including attaching a copy of this Agreement as an exhibit to any filing with the SEC. For the avoidance of doubt, nothing in this Agreement prevents any Party from providing information it reasonably believes to be true to the appropriate governmental authority, including a regulatory, judicial, administrative or other governmental entity to report a possible violation of law or regulation or making another disclosure that is protected under any applicable law or regulation or participating in any investigation or proceeding conducted by any such governmental authority. Any Party who receives a request for the disclosure of the terms of this Agreement, including but not limited to informal requests, governmental or administrative requests, or subpoenas or other processes of law, shall, before responding to such a request, promptly provide notice to the other Party to this Agreement of the
