Contracts I
Restatement Second of Contracts § 77
Illusory and Alternative Promises
A promise or apparent promise is not consideration if by its terms the promisor or purported promisor reserves a choice of alternative performances unless
- each of the alternative performances would have been consideration if it alone had been bargained for; or
- one of the alternative performances would have been consideration and there is or appears to the parties to be a substantial possibility that before the promisor exercises his choice events may eliminate the alternatives which would not have been consideration.
