Acceptance. An express act or implication by conduct that manifests assent to the terms of an offer in a manner invited or required by the offer so that a binding contract is formed. (Chirelstein, Marvin A. 2001. Concepts and Case Analysis in the Law of Contracts.)

Breach of contract is a legal cause of action in which a binding agreement or bargained-for exchange is not honored by one or more of the parties to the contract by non-performance or interference with the other party's performance. If the party does not fulfill his contractual promise, or has given information to the other party that he will not perform his duty as mentioned in the contract or if by his action and conduct he seems to be unable to perform the contract, he is said to breach the contract.
