Item 8.01 Other Events.

As previously reported, Authentidate Holding Corp. was named as the defendant in a claim filed by Shore Venture Group in the federal District Court for the District of New Jersey, under the caption Shore Venture Group, LLC, et al v. Authentidate Holding Corp., Authentidate, Inc. and John T. Botti. The complaint in this case was filed on March 2, 2005 and an amended complaint was filed on or about April 26, 2005. On October 12, 2005, the parties entered into an agreement to arbitrate the claims asserted against us by Plaintiffs. On October 19, 2005, the Court approved and entered a Consent Order referring the case to arbitration by the American Arbitration Association and staying the lawsuit pending resolution of the arbitration. In this case, the claimants seek additional shares of the common stock of our subsidiary, Authentidate, Inc., and had withdrawn a number of other claims in the arbitration, including claims for damages in connection with an alleged copyright infringement and rights under one or more of our patent applications. An arbitration hearing in this matter concluded on September 10, 2007. On December 20, 2007, we received the decision of the arbitrators, which was rendered on December 19, 2007, awarding the claimants damages in the amount $1,079,262 plus interest in the amount of $563,676. The arbitrators further awarded the claimants per diem interest of $303.00 commencing on December 12, 2007 and attorneys’ fees from the first day of arbitral hearing through the post-hearing briefing. The amount of attorneys’ fees to be awarded will be separately determined by the arbitrators. The arbitration award extinguishes any interest of Shore Ventures in any shares of stock or stock options of Authentidate Holding Corp. or Authentidate, Inc.
