A termination clause is a provision in a contract that allows one or both parties to end the agreement early under certain conditions. This type of clause can be included for various reasons, such as if one party fails to perform their obligations, there is a material change in circumstances, or the agreement becomes unlawful. The specific details and requirements for exercising the termination clause will vary depending on the contract, but it generally provides an exit option for both parties should they need or want to end the agreement before its natural conclusion.
