An agreement that is otherwise sufficiently definite to be a contract is not invalid because it leaves particulars of performance to be specified by one of the parties. If particulars of performance are to be specified by a party, the following rules apply:
1. Specification must be made in good faith and within limits set by commercial reasonableness.
2. If a specification materially affects the other party’s performance but is not seasonably made, the other party:
A. is excused for any resulting delay in its performance; and
B. may perform, suspend performance, or treat the failure to specify as a breach of contract.
