[1] We estimated expected volatilities using stock data for select peer public companies over a timeframe similar to the expected term. We selected peer companies using our judgment and as such, expected volatility is a Level 3 input.

[2] We estimated risk-free rates using the U.S. Treasury yield curve in effect as of the valuation dates.

[3] The expected warrant terms are equal to the remaining contractual life of the Private Warrants at each measurement date.
