<p align="left"><font size="2" face="serif">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The General Corporation Law of Delaware provides generally that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, or investigative in nature, by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys&#146; fees) and, in a proceeding not by or in the right of the corporation, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such suit or proceeding, if he acted in good faith and in a manner believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reason to believe his conduct was unlawful.  Delaware law further provides that a corporation will not indemnify any person against expenses incurred in connection with an action by or in the right of the corporation if such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to indemnity for the expenses which such court shall deem proper.</font></p>
<p align="left"><font size="2" face="serif">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our By-Laws provide for indemnification of our officers and directors to the greatest extent permitted by Delaware law for any and all fees, costs and expenses incurred in connection with any action or proceeding, civil or criminal, commenced or threatened, arising out of services by or on behalf of us, providing such officer&#146;s or director&#146;s acts were not committed in bad faith.  The By-Laws also provide for advancing funds to pay for anticipated costs and authorizes the Board to enter into an indemnification agreement with each officer or director.</font></p>
<p align="left"><font size="2" face="serif">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In accordance with Delaware law, our Certificate of Incorporation contains provisions eliminating the personal liability of directors, except for (i)&nbsp;breaches of a director&#146;s fiduciary duty of loyalty to us or to our stockholders, (ii)&nbsp;acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, and (iii)&nbsp;any transaction in which a director receives an improper personal benefit.  These provisions only pertain to breaches of duty by directors as such, and not in any other corporate capacity, e.g., as an officer.  As a result of the inclusion of such provisions, neither Authentidate Holding Corp. nor our stockholders may be able to recover monetary
damages against directors for actions taken by them which are ultimately found to have constituted negligence or gross negligence, or which are ultimately found to have been in violation of their fiduciary duties, although it may be possible to obtain injunctive or equitable relief with respect to such actions.  If equitable remedies are found not to be available to stockholders in any particular case, stockholders may not have an effective remedy against the challenged conduct.</font></p>

In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.</font></p>

Item 6.   Indemnification of Directors and Officers.
The General Corporation Law of Delaware provides generally that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, or investigative in nature, by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) and, in a proceeding not by or in the right of the corporation, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such suit or proceeding, if he acted in good faith and in a manner believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reason to believe his conduct was unlawful.  Delaware law further provides that a corporation will not indemnify any person against expenses incurred in connection with an action by or in the right of the corporation if such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to indemnity for the expenses which such court shall deem proper.
Our By-Laws provide for indemnification of our officers and directors to the greatest extent permitted by Delaware law for any and all fees, costs and expenses incurred in connection with any action or proceeding, civil or criminal, commenced or threatened, arising out of services by or on behalf of us, providing such officer's or director's acts were not committed in bad faith.  The By-Laws also provide for advancing funds to pay for anticipated costs and authorizes the Board to enter into an indemnification agreement with each officer or director.
In accordance with Delaware law, our Certificate of Incorporation contains provisions eliminating the personal liability of directors, except for (i) breaches of a director's fiduciary duty of loyalty to us or to our stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, and (iii) any transaction in which a director receives an improper personal benefit.  These provisions only pertain to breaches of duty by directors as such, and not in any other corporate capacity, e.g., as an officer.  As a result of the inclusion of such provisions, neither Authentidate Holding Corp. nor our stockholders may be able to recover monetary
damages against directors for actions taken by them which are ultimately found to have constituted negligence or gross negligence, or which are ultimately found to have been in violation of their fiduciary duties, although it may be possible to obtain injunctive or equitable relief with respect to such actions.  If equitable remedies are found not to be available to stockholders in any particular case, stockholders may not have an effective remedy against the challenged conduct.

Item 9.   Undertakings
We hereby undertake:
A.      (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereto) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement;
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs A(1)(i) and A(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the
 registration statement.
5
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
B.      For purposes of determining any liability under the Securities Act of 1933, each filing of our annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
C.      Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
