Business Acquisition, Planned Restructuring Activities, Description | | WPCS equity allocation percentage was increased to 16.01%. It had previously been 15%. Consequently, DropCar’s equity allocation percentage is reduced to 83.99% from 85%.As a result of the foregoing changes, the number of shares of WPCS Common Stock that will be issued to DropCar’s securityholders and advisors will be reduced, although the DropCar securityholders and advisors will still own a majority of the issued and outstanding shares of WPCS Common Stock following the Merger. The reduction in the number of shares to be issued by WPCS in the Merger will result in a reduction in the number of shares of WPCS Common Stock that will be allocated to DropCar’s advisors in connection with the Merger. Thus, the Advisory/Commitment Allocation Percentage was reduced to 15.6% from 15.8%. | | | | | |
