[Partnership Agreement] Rufus, Sven, and Igor Are Partners in a Health

[Partnership Agreement] Rufus, Sven, and Igor are partners in a Health Club. They executed a partnership agreement ten years ago. Rufus and Sven want to grow the company and approach Igor with their ideas. First, they want to add two partners into the partnership who have extensive capital. Second, they want to move the club into a new direction, by adding a restaurant and a casino. Third, they want to purchase new exercise equipment from SportsCo.
