Ann: D13 and Raytheon team to provide counter-drone technologies, page-7

A teaming agreement (Teaming Agreement) is a contract between two or more parties (Team Members) that is used to regulate the rights and obligations where one of them pursues a tender or contract with a with a third party (Prime Contract).  Once the Prime Contract is entered into between the third party and Team Member # 1, a sub-contract is executed between Team Member # 1 and the other Team Member(s) to enable Team Member # 1 to discharge its obligations under the Prime Contract.
The benefits of Teaming Agreements are that they allow parties to pool resources for a limited purpose (Permitted Purpose), without necessarily requiring the establishment of a joint venture entity – however, the Team Members could do this if they wanted to.
