AuthentiDate Holding Corp. Announces
First Quarter Results

Schenectady, NY–November 4, 2004–AuthentiDate Holding Corp. (NASDAQ: ADAT) announced today that revenue for the quarter ended September 30, 2004 increased 12% to $3,662,398 from $3,271,223 for the same quarter a year ago.

Revenue for the AuthentiDate segment, which consists of AuthentiDate, Inc., AuthentiDate International, AG, and Trac Medical Solutions, Inc. (TracMed), was $593,426 for the quarter compared to $207,272 for the same period a year ago, an increase of 186%. The DocStar segment reported revenue of $1,405, 670 for the three months ended September 30, 2004 compared to $1,225,201 for the three months ended September 30, 2003, a 15% revenue increase. The DJS segment experienced a slight revenue decrease with revenues of $1,663,302 for the quarter compared with $1,838,750 for the same year ago quarter.

Deferred revenue, mainly due to increases in the AuthentiDate segment, increased from $1,881,277 on June 30, 2004 to $1,975,098 on September 30, 2004. TracMed previously announced the signing of a 60 month sales contract with Rotech Healthcare. During the quarter, the Company recorded $150,000 in deferred revenue related to the Rotech contract and expects a more significant increase in deferred revenue for the quarter ending December 31, 2004 due to this contract as well as other healthcare provider agreements.

The gross profit for the quarter ended September 30, 2004 was up 39% to $1,702,613 compared to $1,226,283 for September 30, 2003. The net loss for the quarter ended September 30, 2004 was $2,906,089 or $0.09 per share compared to a net loss of $1,700,019 or $0.09 per share for the same quarter a year ago.

The Company attributed the increase in the net loss to the Authentidate Segment which incurred increased selling and marketing costs, increased development costs associated with the development of additional features to the core EPM product needed for the application in South Carolina, business development costs related to the Global Electronic Postmark (GEPM) market, as well as increased general administrative costs.

The Company’s cash position as of September 30, 2004, remained strong, reporting close to $72 million in cash on hand.

“With the recent addition of Suren Pai as President and CEO, we believe that our team is now in place to capitalize on the unique opportunity ahead,” stated John Botti, AuthentiDate’s Chairman. “The revenue growth we experienced this past quarter is but a small example of what we believe is attainable over the coming quarters and we now must implement our strategic plan.”
