Ellen and Uncle Moneybags make a contract where Ellen will buy Uncle Moneybags’ boat for $100,000 if Ellen gets a T.V. show contract. Ellen only has $10,000 now and gives it to Uncle Moneybags and says that she will get the rest once she signed the T.V. contract. Uncle Moneybags agrees. However, the studio decides not to offer Ellen the T.V. show contract due to their own budget restraints. If Ellen sues Uncle Moneybags for the $10,000, what type of equitable remedy would this be?
