Final answer:
The number of exceptions in the Nevada revised statutes that invalidate indemnification (NRS 41.0349) is subjective and requires legal research.
Step-by-step explanation:
The number of exceptions in the Nevada revised statutes that invalidate indemnification (NRS 41.0349) depends on the specific statute and its interpretation by the courts. Without having access to the entire Nevada revised statutes and conducting a thorough legal research, it's not possible to determine the exact number of exceptions in NRS 41.0349. However, it's worth noting that the Nevada revised statutes are regularly amended and subject to interpretation by the courts, so the number of exceptions may change over time.
