To the extent required to be disclosed pursuant to Item 1.01 and Item 3.02 of Current Report Form 8-K, the information set forth in response to Item 8.01 of this Current Report on Form 8-K is incorporated by reference to Item 1.01 and Item 3.02 of this Current Report on Form 8-K.

As previously reported, Authentidate Holding Corp. (the “Company” or “AHC”) and Peachstate Health Management LLC, d/b/a AEON Clinical Laboratories (“AEON”) entered into an Amended and Restated Agreement and Plan of Merger (the “Merger Agreement”), and on January 27, 2016, the parties completed the merger. As a result of the merger, AEON became a wholly-owned subsidiary of AHC.

Pursuant to the Merger Agreement, and as previously reported, former members of AEON may be entitled to additional earnout payments, payable by AHC in shares of its common stock (as defined below, the “Earnout Shares”) based upon stockholder approval and the achievement of certain earnings milestones of the AEON business.

To date, the parties have determined that an aggregate of 1,396,126 Earnout Shares have been earned in accordance with the Merger Agreement. On December 15, 2016, the parties entered into Amendment No. 2 (“Amendment No. 2”) to the Merger Agreement to modify the definition of “Target Members” as set forth in the Merger Agreement, and subsequently issued the aforementioned Earnout Shares. Following such issuance, there are 7,168,159 shares of AHC Common Stock outstanding.

Further, as previously reported, the Company announced that on August 7, 2016, the employment of Richard Hersperger, Chief Executive Officer of Authentidate Holding Corp., terminated and that Hanif (“Sonny”) Roshan, the Company’s Chairman, assumed the position of Chief Executive Officer. Since that time, the Company has not been able to enter into a mutually agreeable separation agreement with Mr. Hersperger, as originally anticipated. The Company and Mr. Hersperger continue to dispute Mr. Hersperger’s entitlement to any shares of the Company’s Common Stock and other severance benefits.

The Earnout Shares have been issued in a private placement exempt from registration under Section 4(a)(2) of the Act and Rule 506(b) of Regulation D, because the offer and sale of such securities does not involve a “public offering” as defined in Section 4(a)(2) of the Securities Act, and other applicable requirements were met. The foregoing summary of Amendment No. 2 is qualified in its entirety by reference to the full text of Amendment No. 2, a copy of which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The following exhibit is attached to this Form 8-K:
