That has the contract as well as all other addenda and required. Pay special attention to section 11 "SPECIAL PROVISIONS". That's where you're going to want to add some things to protect yourself as a wholesaler. Also, section 15 "DEFAULT". Once you think you like the changes you've made, have an attorney review it. It shouldn't cost much to have one look over your changes, and it could save you thousands.
Good luck!
