        <footnote id="F1">Each Restricted Stock Unit represents a contingent right to receive one share of OSS common stock. The closing price of OSS on July 2, 2018 was $4.09.</footnote>
        <footnote id="F2">Prior to the Initial Vesting Date, the Vested Ratio shall be zero. On the Initial Vesting Date, the Vested Ratio shall be 1/3, provided the Grantee's service has not been terminated prior to the Initial Vesting Date. For each quarter of Grantee service from the Initial Vesting Date until the Vested Ratio equals 1/1, the Vested Ratio shall be increased by 1/12. This Restricted Stock Unit will be fully vested after three (3) years of service.  The Initial Vesting Date shall be September 1, 2017 to coincide with Grantee's date of hire.</footnote>
