[3] Fair value of ApolloMed’s preferred shares held by NMM NMM currently owns all the shares of ApolloMed Series A preferred stock and Series B preferred stock, which were acquired prior to the Merger. As part of the Merger, the ApolloMed Series A preferred stock and Series B preferred stock are remeasured at fair value and included as part of the consideration transferred to ApolloMed. The fair value of the Series A preferred stock and Series B preferred stock is reflective of the liquidation preferences, claims of priority and conversion option values thereof. In aggregate, the Series A preferred stock and Series B preferred stock were valued to be $19,118,000. The valuation methodology was based on an Option Pricing Method ("OPM") which utilized the observable publicly traded common stock price in valuing the Series A preferred stock and the Series B preferred stock within the context of the capital structure of the Company. OPM assumptions included an expected term of 2 years, volatility rate of 37.9%, and a risk-free rate of 1.8%. The fair value of the liquidation preference for the Series A preferred stock and the Series B preferred stock was determined to be $12,745,000 and the fair value of the conversion option was determined to be $6,373,000 or an aggregate total fair value of $19,118,000.

[4] Fair value of NMM’s 50% share of APA ACO Inc. Prior to the Merger, APAACO was owned 50% by ApolloMed and 50% NMM. NMM’s noncontrolling interest in APAACO has been remeasured at fair value as of the closing date and is added to the consideration transferred to ApolloMed as a result of NMM relinquishing its equity investment in APAACO in order to obtain control of ApolloMed. The fair value of NMM’s noncontrolling interest in APAACO has been estimated to be $5,129,000 using the discounted cash flow method and NMM recorded a gain on investment for the same amount to reflect the fair value of this investment prior the Merger.
