An 'Agreement' is a written document outlining some contractual relationship, an exchange of promises, a performance of some action or grants some right signed by and between one or more parties. In essence, an Agreement is less formal than a contract.
The assignor must agree to assign their rights and duties under the contract to the assignee. The assignee must agree to accept, or "assume," those contractual rights and duties. The other party to the initial contract must consent to the transfer of rights and obligations to the assignee.
