As reported by the Issuer, effective as of July 15, 2019, the Issuer effected a 1-for-50 reverse split of its outstanding ordinary shares, which proportionately raised the par value per ordinary share from NIS 0.03 to NIS 1.5, and caused a corresponding adjustment of the ratio of the number of ordinary shares to American Depositary Shares (“ADSs”) from 50:1 to 1:1 (since the ADSs were otherwise unaffected by that reverse share split). All numbers appearing in this Amendment No. 2 to Schedule 13D are presented on a post-reverse split basis.

All numbers appearing in this Amendment No. 2 to Schedule 13D are presented on a post-reverse split basis.
