This is implied in the clause that requires him to use best efforts to find another position. That clause also means that he is expected to get paid the market rate for the position. If anyone were to pay him much less than they would have paid someone else, UVA would simply sue Groh for the difference. They may not win, but it would cost him enough defending it that it wouldn't matter.
Are you an attorney - this is true attorney speak (I am one). Are the terms of Groh's UVA contract public or were you speculating?
