Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The shares of Class B Common Stock do not have an expiration date. Each share of Class B Common Stock is convertible, at any time at the option of the holder, into one share of Class A Common Stock. In addition, shares of Class B Common Stock that are transferred by the Reporting Person will convert automatically, on a one share-for-one share basis, into shares of Class A Common Stock, except for (i) any transfers to any person that is, and prior to June 30, 2015 was, a member of the Reporting Person, and (ii) any transfer to a "qualified recipient" as defined in the Company's Amended and Restated Certificate of Incorporation.
(2) All of the outstanding shares of Class B Common Stock will convert automatically into shares of Class A Common Stock, on a one share-for-one share basis, on the date when the number of the Company's outstanding shares of Class B Common Stock represents less than 10% of the sum of its outstanding shares of Class A Common Stock and Class B Common Stock.
(3) These shares of Class B Common Stock are owned by IGSB Internal Venture Fund III LLC, a private investment fund managed by Investment Group of Santa Barbara LLC (IGSB). Mr. Rauth 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 members. As a result, Mr. Rauth may be deemed to share voting and dispositive power over these shares with IGSB and its other two members. However, Mr. Rauth disclaims beneficial ownership of these shares, except to the extent of any pecuniary interest he may have therein.
