The closing of the private placement is conditioned upon customary closing conditions and is expected to close by February 9, 2004.

"The completion of this transaction validates our long term viability and strengthens our financial stature with the investment community, our partners and our customers," stated John Botti, Chairman and CEO of AuthentiDate.
