CHECK THE APPROPRIATE BOX BELOW IF THE FORM 8-K FILING IS INTENDED TO SIMULTANEOUSLY SATISFY THE FILING OBLIGATION OF THE REGISTRANT UNDER ANY OF THE FOLLOWING PROVISIONS:

On January 29, 2015, Authentidate Holding Corp. (the “Company”) received a short-term loan of $200,000 (the “Loan Transaction”) from a strategic lender (the “Lender”) pursuant to which the Company issued a secured promissory note to the Lender in the aggregate principal amount of $200,000 (the “Secured Note”). The Secured Note is secured by a first priority lien on certain equipment owned by the Company with a net present value equivalent to the face value of the Secured Note and is due and payable on March 30, 2015. The lien was granted pursuant to a separate security agreement entered into by the Company and the Lender. The Company may prepay the Secured Note in whole or in part at its option. The Secured Note bears interest at the rate of 6% per annum (or 12% per annum upon and during the continuance of any event of default) and is not convertible into equity securities of the Company.

The Secured Note contains events of default customary for similar transactions. Events that may constitute an event of default under the Secured Note include (a) the failure to pay any principal or interest when due; (b) subject to a twenty business day grace period if curable, the Company breaches any covenant or other obligation or condition of the Secured Note or the corresponding security agreement; (c) any representation or warranty made by the Company in the Secured Note or the security agreement shall prove to be materially false or misleading; (d) any default exists under other obligations to pay indebtedness for borrowed money in an amount in excess of $100,000 or a final judgment for amounts in excess of $100,00 are rendered against the Company; (e) the Company voluntarily commences bankruptcy proceedings or consents to certain events such as the appointment of a receiver or custodian or similar bankruptcy proceedings are instituted against the Company and are not dismissed or discharged within 60 days; and (f) the transaction documents cease to create a valid and perfected lien on the material collateral. The Secured Note also contains certain customary covenants made by the Company, including, so long as the Secured Note is outstanding, that the Company will not: (a) incur or create any lien other than permitted liens; (b) engage in any business other than the business engaged in at the time of loan; or (c) change its type of legal entity or state of incorporation. Upon the occurrence and continuation of an event of default, the Lender may declare all outstanding obligations immediately due and payable, and exercise all rights and remedies available under the security agreement and applicable law.
