Explanation of Responses:

1. These Class A Shares were owned by a pension plan of which the Reporting Person is the sole trustee and who, in that capacity, possessed sole voting and investment power over the Shares. However, the Reporting Person did not and does not possess any pecuniary interest in these Shares. As reported above, on December 27, 2017, 139,000 of the Class A Shares were distributed from the pension plan to the beneficiary of that pension plan, which had the effect of reducing the number of Class A Shares owned by the pension plan, and over which the Reporting Person possesses beneficial ownership, to 52,830 Shares.

2. These Class A Shares are held by a limited liability company, of which the Reporting Person is the sole manager. In that capacity, the Reporting Person possesses sole voting and dispositive power over all of these Shares, but disclaims beneficial ownership over these Shares except to the extent of his pecuniary interest therein.

3. These Class A Shares are owned by IGSB IVP III, LLC, a private investment fund managed by Investment Group of Santa Barbara LLC ("IGSB"). The Reporting Person is one of three members of IGSB and all decisions regarding the voting and disposition of these Shares require the unanimous approval of all three of IGSB's members. As a result, the Reporting Person may be deemed to share voting and dispositive power over these Shares with IGSB and its other two members. However, the Reporting Person disclaims beneficial ownership over these Shares, except to the extent of any pecuniary interest therein.
