Explanation of Responses:

1. 250,000 shares (the "LTIP Shares") of common stock, par value $0.0001 per share, of the issuer were received as compensation for the reporting person's service as a member of the issuer's board of directors pursuant to the issuer's 2018 Long-Term Stock Incentive Plan (the "Grant"). The LTIP Shares associated with the Grant are scheduled to vest in equal quarterly installments over one year, beginning on the first to occur of March 20th, June 20th, September 20th or December 20th after the Grant Date and thereafter on each March 20th, June 20th, September 20th and December 20th until fully vested, so long as the reporting person remains in the service of the issuer on each such date.

Remarks:

This Form 4/A is being filed to correct the vesting terms of the restricted shares previously reported by the Reporting Person. Due to a scrivener's error, the Reporting Person's prior Form 4 reported that the shares vest quarterly over a three-year period. The shares instead vest in equal quarterly installments over one year, as described in Footnote 1. No other changes have been made to the original Form 4.
