Explanatory Note

Lazarus Investment Partners LLLP, a Delaware limited liability limited partnership (“Lazarus Partners”), Lazarus Management Company LLC, a Colorado limited liability company (“Lazarus Management”), and Justin B. Borus (collectively “Reporting Persons”) originally reported their holdings of securities of the Issuer on Schedule 13G. Reporting Persons holdings included Warrants exercisable for Common Stock that required consent of the Issuer’s shareholders to be exercisable. On or about June 21, 2012, the Issuer’s shareholders approved the exercisability of the Warrants resulting in Reporting Persons having to include the Warrants in their holdings under Section 13(d), taking Reporting Persons’ percentage ownership above 20% and requiring the Reporting Persons to report on this Schedule 13D. Reporting Persons are filing this Amendment to reflect their additional interest in the Issuer’s Common Stock resulting from the automatic conversion of the Issuer’s Series C Preferred Stock and accrued dividends as a result of a shareholder vote on April 5, 2013 (the Series C was not convertible prior to such vote).

Item 1. Security and Issuer.

(a) This statement on Schedule 13D relates to the common stock of Authentidate Holding Corp., a Delaware corporation (the “Issuer”).

(b) The principal executive offices of the Issuer are located at Connell Corporate Center, 300 Connell Drive, 5th Floor, Berkeley Heights, N.J. 07922.

Lazarus Management is the investment adviser and general partner of Lazarus Partners and Lazarus Macro Micro Partners LLLP (“Macro Micro Partners”), and consequently may be deemed to have voting control and investment discretion over securities owned by Lazarus Partners and Macro Micro Partners. Justin B. Borus (“Mr. Borus”) is the managing member of Lazarus Management.

Its shares are included in Lazarus Management’s and Mr. Borus’ holdings, for the reasons set forth above. The foregoing should not be construed in and of itself as an admission by Lazarus Management or Mr. Borus as to beneficial ownership of the shares owned by Lazarus Partners or Macro Micro Partners. Each of Lazarus Management and Mr. Borus disclaims beneficial ownership of the securities set forth in this Schedule 13D, except to the extent of its or his pecuniary interests therein.

The business address for the Reporting Persons is c/o Lazarus Management Company LLC, 3200 Cherry Creek South Drive, Suite 670, Denver, Colorado 80209. Mr. Borus is a United States citizen.

Item 3. Source and Amount of Funds or Other Consideration.

The Reporting Persons hold shares of the Issuer’s common stock and warrants to purchase common stock that were acquired for cash with personal funds or were received in exchange for accrued dividends or accrued interest or in consideration of extensions of payment. On or about October 12, 2010, Lazarus Partners purchased 500,000 Units from the Issuer for a purchase price of $2,000,000.00 with each unit consisting of six (6) shares of Common Stock, one (1) share of Series C Convertible Preferred Stock and a warrant to purchase five (5) shares of Common Stock. The Series C Preferred Stock was not convertible without shareholder approval, but converted (together with accrued dividends) into a total of 1,420,616 shares of Common Stock on April 5, 2013 when shareholder approval was obtained. On or about October 6, 2011, Lazarus Partners purchased from Issuer 1,428,571 Units for $1,000,000.00 with each Unit consisting of one (1) share of Common Stock and a warrant to purchase one-half (1/2) a share of Common Stock. On or about March 9, 2012, Lazarus Partners purchased a $1,000,000.00 promissory note from the Issuer and stock purchase warrants exercisable for 1,492,537 shares of Common Stock for a purchase price of $1,000,000.00.

On September 28, 2012, Lazarus also received Warrants to purchase 542,636 shares at an exercise price of $1.34 a share in consideration of an extension of the maturity date of a promissory note. These Warrants also become exercisable on March 28, 2013. The 7,500 shares held by Macro Micro Partners were purchased on the open market.

Item 4. Purpose of Transaction.

(a)-(i) The securities of the Issuer were purchased for investment in the ordinary course of Reporting Persons’ business and not with the purpose nor with the effect of changing or influencing control of the Issuer nor in connection with or as a participant in any transaction having such purpose or effect. Lazarus Partners presented a letter to the Company’s Board of Directors in February 2013 to advocate its position set forth in that letter which subject to certain conditions advocated for a financing in which Lazarus Partners would participate and advocated for certain changes in the members of the Board of Directors and management, including, but not limited to that a representative of Lazarus Partners would become a member of the Board and Chairman of the Board. The letter did not lead to a definitive agreement regarding the subject matter proposed therein, however, Lazarus Partners intends to stay in ongoing dialogue with the Issuer regarding the composition of the Issuer’s Board of Directors and management, and may advocate for certain changes in the Issuer’s Board of Directors and management. Lazarus Partners may also nominate an individual to serve on the Board of Directors of the Issuer, pursuant to the Board Nomination and Observer Agreement dated September 25, 2012 between it and the Issuer, as amended. Lazarus Partners also intends to stay in ongoing dialogue with the Issuer regarding alternate transactions and methods in which Lazarus Partners may participate intending to strengthen the capitalization of the Issuer.

Item 5. Interest in Securities of the Issuer.

(a) Reference is made to items 7, 9, 11 and 13 of pages 2-4 of this Schedule, which items are incorporated by reference. The securities reported on this Schedule consist of 5,801,357 shares of Common Stock and Warrants to purchase an additional 4,001,241 shares of Common Stock. The calculation of percentage of beneficial ownership in Item 13 of page 2 – 4 was calculated using information from Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on April 8, 2013, in which the Issuer stated that the number of shares of its common stock, $0.001 par value per share, outstanding after conversion of the Series C Preferred Stock was 30,655,285 shares.
