obligation to conduct business exclusively with the other Party, to offer other

         2.2 Establishment of Joint Entities

         (a) In accordance with Article III, the Parties will cause to be
established in Germany an entity under the name "Authentidate International
Holdings AG" ("International") provided that such firm name is available for
registration at any competent court. The Parties agree not to market the name of
International prior to its approval by the competent German authorities. The
principal operating office of International shall be located in Rahden, Germany,
but it is mutually understood that, for the reason of practicability,
International might have a registered office in Rahden for a transition period.

         (b) As soon as practicable, and from time to time as the Parties
implement the Business Plans, the Parties will determine whether to establish in
each country in the Territory, an entity under a name which is mutually
acceptable to the Parties. Each Joint Entity will either be wholly owned by
International or will be owned by the Parties in the same proportion as the
ownership of International.

         (c) Each Joint Entity which is established by the Parties shall have
constituent documents (articles of association, articles of incorporation,
by-laws and the like) as are consistent with local laws, as well as the rights,
obligations and remedies provided in this Agreement. The Joint Entities shall be
established in a manner which will provide limited liability to the Parties and
the most favorable tax treatment to the Joint Venture, unless otherwise agreed
by the Parties.

         (d) Unless the Parties agree that each Joint Entity established after
the formation of International shall exist as a wholly owned subsidiary of
International, upon formation of each of the Joint Entities, each of the Parties
shall be entitled to receive the shares (or such other evidence of ownership as
is recognized with respect to the entity) representing their respective
ownership interests in each of such Joint Entities, subject to the requirements
of Article IV.

         2.3 No Partnership

                  Nothing in this Agreement shall be construed as creating
between the Parties a partnership, fiduciary or other similar relationship or a
joint venture except as expressly provided for herein. Nothing in this Agreement
shall create or imply any exclusive relationship or any obligation to inform any
other Party, offer to any other Party or to include any other Party in any
opportunity which may be available to one of the Parities in the future except
as provided in the License.

(the "Securities Act").

         (b) Windhorst has conducted its own due diligence review of Bitwise and

connection with the transactions contemplated hereby.

         (c) It has such knowledge and experience in finance, securities,
investments and other business matters so as to be able to protect its interests
in connection with this transaction, and its investment in Bitwise and
Authentidate is not material when compared to its total financial capacity.

         (d) It understands the various risks of an investment in Bitwise and
Authentidate as proposed herein and can afford to bear such risks, including,
but not limited to, the risks of losing its entire investment.

         (e) It acknowledges that no market for the Bitwise Warrants and
Authentidate Warrants, or shares of common stock of Authentidate presently
exists and none may develop in the future and that it may find it impossible to
liquidate its investment at a time when it may be desirable to do so, or at any
other time.

         (f) It has been advised that the Bitwise Warrants, Authentidate
Warrants and the Warrant Shares have not been registered under the Securities
Act, and that all the foregoing securities will be issued on the basis of the
statutory exemption provided by Section 4(2) of the Securities Act and/or
Regulation D promulgated thereunder relating to transactions by an issuer not
involving any public offering and under similar exemptions under certain state
securities laws; that this transaction has not been reviewed by, passed on or
submitted to any Federal or state agency or self-regulatory organization where
an exemption is being relied upon, and that Bitwise's and Authentidate's
reliance thereon is based in part upon the representations made by Windhorst in
this Agreement. Windhorst acknowledges that it has been informed by Bitwise and
Authentidate, or is otherwise familiar with, the nature of the limitations
imposed by the Securities Act and the rules and regulations thereunder on the
transfer of securities. In particular, Windhorst agrees that, except for

be required to give any effect to any such sale, assignment or transfer, unless
(i) the sale, assignment or transfer of the foregoing securities are registered
under the Securities Act, (ii) the foregoing securities are sold,

                                       19
<PAGE>   19

of Rule 144 under the Securities Act, it being understood that Rule 144 is not
available at the present time for the sale of the foregoing securities, or (iii)
such sale, assignment, or transfer is otherwise exempt from registration under
the Securities Act. Windhorst acknowledges that the Bitwise Warrant,
Authentidate Warrants and the shares underlying the Bitwise and Authentidate
Warrants shall be subject to a stop transfer order and the certificate or
certificates evidencing any underlying shares shall bear the legend set forth in
Section 7.4.

         (g) Except for transfers to PFK, Windhorst will acquire the Bitwise and
Authentidate Warrants for its own account for investment and not with a view to
the sale or distribution thereof or the granting of any participation therein,
and that it has no present intention of distribution or selling to others any of
such interest or granting any participation therein.

                                 CONFIDENTIALITY

         11.1 Confidentiality, Non-Disclosure

         (a) Each of Windhorst, Bitwise and Authentidate covenants and agrees,
on behalf of themselves, their Affiliates, parents, subsidiaries, directors,
officers, employees, agents, successors and assigns, that they shall not, at any
time during or after the termination of this Agreement, except when acting on
behalf of and with the written authorization of the other Parties, make use of
or disclose to any person, corporation, or other entity, for any purpose
whatsoever, any trade secret or other Confidential Information and not to use
any such Confidential Information for any purpose other than the purpose for
which it was originally disclosed to the receiving party. No Party will disclose
the others' Confidential Information to its employees and agents except on a
"need-to-know" basis.

         (b) Confidential Information means any information of a Party disclosed
to the other party in the course of this Agreement, which is identified as, or
should be reasonably understood to be, confidential to the disclosing Party,
including, but not limited to, trade secrets and confidential information
disclosed to the Parties or known by them as a consequence of their transactions
with Authentidate, whether or not pursuant to this Agreement, and not generally
known in the industry, concerning the business, finances, methods, operations
now-how, trade secrets, data, technical processes and formulas, source code,
product designs, sales, cost and other unpublished financial information,
product and Business Plans, projections, marketing data, information, research
and development, customers, pricing and information relating to proposed
expansion and this Agreement and all exhibits hereto. Confidential Information
will not include information which: (a) is known or becomes known to the
recipient directly or indirectly from a third-Party source who obtained the
information lawfully other than one having an obligation of confidentiality to
the providing party; (b) is or becomes publicly available or otherwise ceases to
be secret or confidential, except through a breach of this Agreement by the

                                       22
<PAGE>   22
recipient; or (c) is or was independently developed by the recipient without use
of or reference to the providing party's Confidential Information, as shown by
evidence in the recipient's possession.

         (c) The Parties acknowledge and agree that each may disclose
Confidential Information: (a) as required by law or the rules of the National
Association of Securities Dealers, Inc. or any applicable securities exchange or
any governmental authority required by law; (b) to their respective directors,
officers, employees, attorneys, accountants and other advisors, who are under an
obligation of confidentiality, on a "need-to-know" basis; (c) to investors or
joint venture partners, who are under an obligation of confidentiality, on a
"need-to-know" basis; or (d) in connection with disputes or litigation between
the parties involving such Confidential Information and each Party will endeavor
to limit disclosure to that purpose and to ensure maximum application of all
appropriate judicial safeguards (such as placing documents under seal). In the
event a Party is required to disclose Confidential Information as required by
law, such party will, to the extent practicable, in advance of such disclosure,
provide the disclosing party with prompt notice of such requirement. Such Party
also agrees, to the extent legally permissible, to provide the disclosing party,
in advance of any such disclosure, with copies of any information or documents
such party intends to disclose (and, if applicable, the text of the disclosure
language itself) and to cooperate with the disclosing party to the extent the
disclosing Party may seek to limit such disclosure.

         11.2 Use of Authentidate Business Plan

                  Windhorst and International, and their Affiliates, parents,
subsidiaries, directors, officers, employees, agents, successors and assigns
covenant and agree to (i) use the Authentidate Business Plan only during the
term of this Agreement and for the sole purpose set forth herein; (ii) not to
copy, in whole or in part, the Authentidate Business Plan, except as needed to
implement the Business Plan of International; (iii) not to disclose the
Authentidate Business Plan or any portion thereof outside of International; (iv)

employees who have an need to know in order to implement International's
Business Plan; and (v) to return the Authentidate Business Plan, including all
copies, records and representations thereof, to Authentidate upon the

         (a) This Article XI shall survive the termination of this Agreement.

         (b) The Parties acknowledge that damages alone may not be an adequate
remedy for any breach by any Party of this Article XI, and accordingly, each
expressly agrees that, in addition to any other remedies which each may have,
each shall be entitled to request injunctive relief in a court of competent
jurisdiction.

                                   ARTICLE XII
                              RESTRICTIVE COVENANT

         12.1 Restrictive Covenant

         (a) During the term of this Agreement and for a period of one year
after any termination of this Agreement, except for a termination based on a
default in or breach of this Agreement or the License by Bitwise or
Authentidate, Windhorst agrees that it will not, directly or indirectly enter
into or become associated with or engage in any other business (whether as a
partner, officer, director, shareholder, employee, consultant, or otherwise),
which business is primarily involved in the manufacture, development,
distribution, marketing and/or sales of technology intended to verify the
authenticity of digital images by means similar to those described in
Authentidate's patent application in the Territory or geographical areas of
operation of International and the Joint Entities.

         (b) During the term of this Agreement, Bitwise and Authentidate agrees
that they will not, directly or indirectly enter into or become associated with
or engage in any other business in the Territory (whether as a partner, officer,
director, shareholder, employee, consultant, or otherwise), which business is
primarily involved in the manufacture, development, distribution, marketing
and/or sales of the Service.

         (c) After any termination of this Agreement, nothing in this Article
XII shall be construed to prevent Bitwise and Authentidate from developing,
distributing, marketing or selling its own products and Technology in the
Territory served by International pursuant to this Agreement. Similarly, after
any termination of this Agreement, and the one year non-compete period, if
applicable, Windhorst shall have the ability to develop and market a service to
compete with the Authentidate Business Plan so long as such service was not
developed in violation of Articles XI or XII or any of Authentidate's patent or
other rights.

         12.2 General

         (a) The Parties acknowledge and agree that the covenants contained in
this Article XII are fair and reasonable and of a special unique character which
gives them peculiar value and exist in order to protect the Parties and that the
Parties would not have entered into this Agreement without such covenants being
made to it.

         (b) If any court shall hold that the duration or geographic scope of
the non-competition clause, or any other restriction contained in this Article
XII is unenforceable, it is our intention that same shall not thereby be
terminated but shall be deemed amended to delete therefrom such provision or
portion adjudicated to be invalid or unenforceable or in the alternative such
judicially substituted term may be substituted therefor.

         (c) The Parties further acknowledge that damages alone will not be an
adequate remedy for any breach by any Party of the covenants contained in this
Article XII, and

                                       24
<PAGE>   24
accordingly, each expressly agrees that, in addition to any other remedies which
each may have, each shall be entitled to injunctive relief in a court of
competent jurisdiction.

         (d) The Parties acknowledge that the covenants contained in this
Article XII are separate and distinct from, and shall not be merged with, any
similar covenants made by Windhorst, Bitwise and Authentidate in any other
agreement, document or understanding.

         (e) The provisions of this Article XII shall survive the termination of
this Agreement.


                                  ARTICLE XIII

         13.1 Mutual Indemnity

         (a) Each Party represents and warrants to the other Party that such
Party has the full corporate right, power and authority to enter into this
Agreement and to perform the acts required of it hereunder; and the execution of
this Agreement by such Party, and the performance by such Party of its
obligations and duties hereunder, do not and will not violate or contravene any
applicable law or regulation or any agreement to which such Party is a party or
by which it is otherwise bound, and when executed and delivered by such Party,
this Agreement will constitute the legal, valid and binding obligation of such
Party, enforceable against such Party in accordance with its terms. Each Party
agrees to indemnify and hold harmless each other Party to this agreement for a
breach of the foregoing representations and warranties on such terms as set
forth in this Agreement.

         13.2 Additional Indemnity By International

         International shall defend, indemnify and hold harmless Windhorst,
Bitwise and/or Authentidate (the "Indemnified Parties"), and their affiliates,
directors, officers, employees and agents, against and from any cause of action,
claim, action or suit, including claims for civil liability, for recovery of any
damages, losses or injuries, as well as all costs and reasonable attorneys' fees
relating thereto arising out of any use by International of the Technology. The
Indemnified Parties shall give International prompt written notice of any patent
infringement claim against any them.

                                   ARTICLE XIV

announcement relating to the subject matter of this Agreement without the prior
written approval of the other Parties; provided, however, that any Party may

law or any listing or trading agreement concerning its publicly-traded
securities (in

                                       25
