(1) To facilitate the business combination (the "Business Combination") between Stellar Acquisition III Inc. (the "Issuer") and Phunware Inc. ("Phunware") consummated on December 26, 2018, Magellan Investments Corp. and Firmus Investments Inc. (the "Sponsors") agreed to assign an aggregate of 123,632 shares of common stock issued to the Sponsors in 2016 (the "Sponsor Shares") to certain investor.
(2) George Syllantavos is the sole officer and director of each of the Sponsors and accordingly is deemed the beneficial owner of the shares held by the Sponsors and has sole voting and dispositive control over such securities.
(3) In connection with the Business Combination, the Sponsors agreed to assign an aggregate of 89,702 Sponsor Shares to certain service providers.
(4) In connection with the Business Combination, the Sponsors agreed to forfeit an aggregate of 310,495 Sponsor Shares at no cost.
(5) The Sponsors acquired these warrants for a purchase price of $0.50 per warrant in connection with the Issuer's initial public offering. The warrants become eligible for exercise 30 days following the consummation of the Business Combination. Because the exercise of the warrants was contingent upon the closing of the Issuer's initial business combination, these warrants were not reported at the time of acquisition. The acquisition is being reported now in connection with the consummation of the Business Combination on December 26, 2018.
(6) In connection with conversion of promissory notes previously issued to the Sponsors, the Sponsors were issued an aggregate of 1,546,848 warrants.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
