Item 5: Other Events.

     On August 16, 2004, Authentidate Holding Corp. (“Authentidate”) disclosed that its subsidiary Trac Medical Solutions, Inc. confirmed that one of the largest U.S. providers of home healthcare products and services has entered into an agreement to utilize Trac Medical’s CareCert Service through a reseller engaged by Trac Medical. The Agreement provides that the customer shall pay a fixed fee of $3,000,000 to use Trac Medical’s electronic healthcare documentation processing service and process up to 5,000,000 transactions during a five year term, unless the customer exercises a right to convert to a standard pricing model at the end of 2005. If the customer exercises this right, the total value of the contract would be reduced to $1,200,000. Trac Medical will receive net revenues from the contract equal to approximately 72.5% of the total value of the contract, after giving effect to payment of reseller fees and royalties.
