Gaither entered into a contract with a nonprofit corporation whereby Gaither would receive $700 per month while in medical school, provided that he would return to his small hometown, Chester, to practice medicine for ten years after becoming a licensed physician. The residents of Chester voted approval of bonds to construct a medical clinic. Gaither practiced medicine in Chester for about five weeks but then left for Mt. Clement. Do the representatives of the medical clinic and the citizens of Chester have a right to sue Gaither? Explain.
