Explanation of Responses:

1. On May 9, 2019 the Issuer's board of directors approved compensation to be paid to the Issuer's non-executive directors for services provided to the Issuer during 2019. The reporting person is an non-executive director. As compensation for their services, each non-executive director was awarded options for shares of common stock having an exercise price of $1.00. The total number of option shares awarded was based on the services provided by the director. These services include Board participation, committee participation, committee chair responsibilites and lead director responsibilities, if any. The shares of common stock are issued from the Company's 2011 Equity Incentive Plan. The right to purchase the option shares vests in equal increments as follows: the right to purchase 21,625 shares vested on May 9, 2019 and the right to purchase the remaining 64,875 shares will vest in equal increments on the last day of each calendar quarter.

Remarks:

The purpose of this amendment to the Form 4 filed by the reporting person on May 13, 2019 (the "Original Form 4") is to provide corrected information relating to the option grant which is the subject of the report. The Original Form 4, together with the Form 4 filed on July 3, 2019, reported only that portion of the option grant that vested on May 9,2019 and June 30, 2019. This amendment reports the entire grant.
