Schedule of valuation assumptions

MRV uses the Black-Scholes option pricing model to estimate the fair value of stock option awards or related modifications. The Black-Scholes model requires the use of subjective and complex assumptions, including the option's expected life and the underlying stock price volatility. MRV bases volatility on the Company's historical quoted prices and peer company data.
