Are you being asked to speak at an event, panel, or part of a workshop? This Agreement will allow you to lay out, in clear, written terms, what you will be discussing, how much you will be paid (or not paid), a description of the event, and importantly, it will help you retain your IP rights to what you're bringing to the table. Specifically, the "background work" ownership, which is very important if the event host is seeking to record the event and reuse your material.
