1. Existence of a valid contract;
2. Every contract in Nevada contains an implied covenant to act in good faith in performance and enforcement of the contract;
3. Justifiable expectation by the plaintiff to receive certain benefits consistent with the spirit of the agreement;
4. Defendant performed in a manner that was in violation of or unfaithful to the spirit of the contract (the terms of the contract are complied with in a literal sense, but the spirit of the contract is breached);
5. The existence of a special relationship of trust between the plaintiff and defendant;
6. Unfaithful actions by the defendant were deliberate;
7. Causation and damages; and
8. Punitive Damages.
