4. | Mutual Release by All Parties. Each party hereby does and shall, for itself and its successors, predecessors, parents, subsidiaries, stockholders, past and current employees, officers, trustees, directors, board members, representatives, agents, and assigns in their official and individual capacities (collectively, the “Releasing Parties”), release the other party and its successors, predecessors, parents, subsidiaries, partnerships, associated and affiliated companies, related entities, past and current officers, trustees, directors, members, board members, employees, agents, attorneys, insurance companies, and assigns in their official and individual capacities (collectively, the “Released Parties”) from any and all claims, actions, causes of action, grievances, suits, charges, or complaints of any kind or nature whatsoever, that the Releasing Parties ever had or now have up to the Effective Date, arising from or relating to the payment of certain Milestone Payments, including any payment or non-payment thereof, whether fixed or contingent, liquidated or unliquidated, known or unknown, suspected or unsuspected, and whether arising in tort, contract, statute, or equity, before any federal, state, administrative, local, or private court, agency, arbitrator, mediator, or other entity, regardless of the relief or remedy. The Releasing Parties acknowledge and agree that they are aware that statutes exist that render null and void releases of any claims, rights, demands, liabilities, actions and causes of action which are unknown to the Releasing Parties at the time of execution of the release. The Releasing Parties expressly waive, surrender and agree to forego any protection to which they otherwise would be entitled against one another by virtue of the existence of any such statute in any jurisdiction. The Releasing Parties each retain the rights and remedies expressly or impliedly provided to the Releasing Parties by the original terms of the Agreement which are not amended in this Amendment. |
