Explanation of Responses:

( 1 )Pursuant to the terms of the Class B Common Stock, the Reporting Persons converted shares of Class B Common Stock into shares of Class A Common Stock. ( 2 )On December 14, 2018, the Reporting Persons filed a Form 4, which inadvertently excluded the distribution of certain shares of the Issuer's Class B Common Stock (the "Distributed Shares"). This amendment corrects the exclusion of the Distributed Shares. This Form 4 amendment amends and restates the Form 4 filed by the Reporting Persons on December 14, 2018 in its entirety. ( 3 )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 and has no expiration date. In addition, each share of Class B Common Stock will convert automatically into one share of Class A Common Stock upon (1) any transfer, whether or not for value and whether voluntary or involuntary or by operation of law, except for certain transfers described in the Issuer's certificate of incorporation, including, without limitation, certain transfers for tax and estate planning purposes or (continued to Footnote (4)) ( 4 )(continued from Footnote (3)) (2) the death or disability, as defined in the Issuer's certificate of incorporation, of the applicable Class B common stockholder (or nine months after the date of death or disability if the stockholder is one of the Issuer's founders). In addition, on the first trading day following the date on which the outstanding shares of Class B Common Stock represent less than 10% of the aggregate voting power of the Issuer's then outstanding capital stock, all outstanding shares of Class B Common Stock shall convert automatically into Class A Common Stock, and no additional shares of Class B Common Stock will be issued.

Rogers Novak, Jr. (collectively, the "Managing Members") are the managing members of NBCV. Each of NBCV and the Managing Members disclaim beneficial ownership of all the shares owned by NBVPV and this report shall not be deemed an admission that either is the beneficial owner of such shares for purposes of Section 16 or for any other purpose, except to the extent of their pecuniary interests therein. ( 6 )Represents a pro rata distribution without additional consideration by NBVPV to its limited partners only, and not to its general partner NBCV. ( 7 )The reported securities are owned directly by Novak Holdings, LLC ("NH"). Mr. Novak is the sole general member of NH. ( 8 )The reported securities are owned directly by Wells Fargo Bank NA FBO E.R. Novak Jr. MGD IRA ("IRA"). Mr. Novak has sole voting and dispositive power of these shares.

( 10 )Represents a distribution without additional consideration by NBCV to its members, excluding members affiliated with the Managing Members. ( 11 )Represents a pro rata distribution without additional consideration by NBVPV to NBCV.
