Upon closing, those officers (Nelson, Rich, Smith, President Jeffry Hecklinski) and five directors (Peter Borish, Greg Economou, Roger Mason, Daniel Nelson, Jeffry Hecklinski) resigned. Jerry Tang was elected director and named CEO, and Jolienne Halisky was appointed CFO. Options and warrants to buy Signing Day shares were converted into options/warrants for BlockchAIn shares at the 0.09334 ratio, with exercise prices adjusted and options immediately fully vested.
