Explanation of Responses:

( 1 )This transaction represents the sale of the reporting person's 0.1% membership interest in two limited liability companies on August 26, 2019. The reporting person resigned as manager of both limited liability companies and as part of that transaction sold his 0.1% membership interest in each limited liability company to the new manager. The two limited liability companies own in the aggregate 257,179 shares of the Issuer's common stock. Therefore, the reporting person in the aggregate beneficially owned 257 shares of the Issuer's common stock through his membership interest in the two limited liability companies. ( 2 )The reporting person sold his 0.1% interest in each limited liability company for an aggregate purchase price that took into account all assets and liabilities of each limited liability company. The price reported in Column 4 represents the portion of the aggregate purchase price for each limited liability company interest attributable to the shares of the Issuer's common stock beneficially owned by the reporting person based on the average of the high and low reported trading prices of the Issuer's common stock on August 26, 2019. ( 3 )The reporting person previously reported 56,392 shares of the Issuer's common stock held by a limited liability company for which the reporting person reported that he was a manager, but not a member. On August 26, 2019, the reporting person also resigned as manager of this limited liability company. ( 4 )Shares are held by trusts of which the reporting person is a trustee, but not a beneficiary. The reporting person disclaims beneficial ownership of these shares.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
