This Form 4 is being filed by Quantum Ventures LLC ("Quantum Ventures"). Messrs. Schaible, Caamano and Patel are the three managers of Quantum Ventures. Any action by Quantum Ventures with respect to the founder shares held by it, including voting and dispositive decisions, requires a majority vote of the board of managers. Accordingly, under the so-called "rule of three," because voting and dispositive decisions are made by a majority of Quantum Ventures' managers, none of the managers of Quantum Ventures is deemed to be a beneficial owner of Quantum Ventures' securities, even those in which such manager holds a pecuniary interest. Accordingly, none of such individuals is deemed to have or share beneficial ownership of the founder shares held by Quantum Ventures.
