Equity Share Agreement

[Baze M.]

Hello BP!  I have an individual that's a lead developer for large mixed use community.  His company has offered me small percentage of the development project in exchange for my consulting services and guidance.  I've known the developer practically my whole life, however I'd still like to get my equity share in writing.  Is there a sample agreement or template someone can provide that will allow me to get my percentage of the project in writing?

Thanks!
