Ace Investment has entered into a written contract to purchase an office building from Goodale Incorporated. The sales price isall cash to the seller. Prior to the closing, Ace assigns its rights under the contract to Zeb Investors. Zeb shows up

at the closing with the cash to buy the office building. Zeb is a competitor of Goodale and so Goodale does not

want to sell the office building to Zeb, even though Goodale was notified of the assignment by Ace. Can Goodale refuse to sell to Zeb (answer Yes or No)? Clearly explain how you came to this answer.
