Are you an employee (W-2) or contractor (1099)? In the latter case there is an expectation that you have multiple "clients". In either case, if this happened to me I would talk (as in, in your next 1:1 meeting or phone call), not by email, to communicate that at this point I need to keep my options open but if that ends up happening then it sounds great -- and also my hourly rate at that point will change to $(22 + X).
