Explanation of Responses:

1. The reporting person exercised options to acquire 9,448 shares of common stock by submitting and relinquishing to the issuer options to purchase an additional 26,552 shares of common stock. These additional options to purchase 26,552 shares of common stock constituted payment of the exercise price, using the 10-day volume weighted average price dated August 25, 2017 of $6.0334. As a result of this transaction, the reporting person increased her stock ownership by 9,448 shares of common stock and reduced the number of options owned by 36,000 (9,448 exercised plus 26,552 used to pay the exercise price).
