hereby acknowledged, AGREE as follows:

         1.       Effective as of April 30, 2002 (the "Separation Date"),

retained by Presstek, and providing to Presstek any documents in his possession
or under his control relating to the litigation, business or investigatory
matter. Presstek agrees to provide Hallman with reasonable notice of the need
for assistance when feasible, to schedule such assistance in such a manner as
not to interfere with any alternative employment obtained by Hallman when
possible and to reimburse Hallman for the reasonable cost of his time.

               EMPLOYEE WORK PRODUCT AND CONFIDENTIALITY AGREEMENT

In consideration and as a condition of employment or continued employment by
Presstek, Inc. or any subsidiary, division or affiliate thereof (collectively
"Presstek"), the compensation paid therefor and the disclosure by Presstek of
confidential and proprietary information, the undersigned employee (the
"Employee") agrees as follows:

(a)      Employee acknowledges that in the course of his or her employment,
Employee will (i) be exposed to valuable confidential and proprietary
information owned exclusively by Presstek or its licensors, and (ii) foreseeably
create for the sole and exclusive benefit of Presstek, additional valuable
confidential and proprietary information. Employee agrees to treat all such
information as confidential and will not during his or her employment by
Presstek or thereafter at any time disclose to others (except as his or her
duties at Presstek may require) or use for his or her own benefit any Presstek
proprietary information, including without limitation, any trade secrets, know
how or confidential information pertaining to the business, work or
investigations of Presstek.

(b)      Employer agrees that all workproduct, including but not limited to
ideas, inventions, improvements, discoveries, computer code, technical or
business innovations, advertising and marketing materials, company policies and
procedures, presentations and customer and prospect lists (collectively
"Workproduct") created by Employee or under Employee's discretion or
supervision, whether or not conceived during regular work hours or otherwise,
which are along the lines of the business, work or investigations of Presstek or
which result from or are suggested by any work Employee does for Presstek,
except those workproducts acknowledged by Presstek which are listed and
described in attached Schedule A to this Agreement, shall be the sole and
exclusive property of Presstek, that any and all patents, copyrights and other
proprietary interests therein shall belong to Presstek, and that the other
provisions of this Agreement shall fully apply to all such Workproduct.

(c)      Employee hereby assigns and transfers to Presstek, his or her entire
right, title and interest in and to all inventions, improvements or discoveries
(whether or not patentable) made or conceived or first reduced to practice by
him or her, whether solely or jointly with others, during the period of his or
her employment with Presstek, whether or not conceived during regular work hours
or otherwise, which are along the lines of the business, work or investigations
of Presstek or which result from or are suggested by any work Employee does for
Presstek.

<PAGE>

(d)      Employee acknowledges that all copyrightable Workproduct arising under
this Agreement, including derivative works developed therefrom, is a work made
for hire under 17 U.S.C. ss101 et seq. (the "Copyright Act"), which shall be the
sole and exclusive property of Presstek. To the extent that any copyrightable
Workproduct created by Employee may not be the sole property of Presstek and/or
may not be a work made for hire under the Copyright Act, Employee hereby
transfers, grants and assigns to Presstek, its successors and assigns, all
copyrights and all other right, title and interest in and to such Workproduct
developed under this Agreement.

(e)      Employee will assist Presstek in any reasonable manner to obtain for
its own benefit patents, copyrights or other legal protection thereon in any and
all countries, and will execute when requested, patent, copyright and other
applications and assignments and any other lawful documents deemed necessary by
Presstek to carry out the purposes of this Agreement, all without further
consideration than provided for herein, but at the expense of Presstek. Employee
further agrees that the obligations stated in this paragraph shall continue
beyond the termination of his or her employment with Presstek, but if Employee
is then called upon to render such assistance, Employee shall be entitled to a
fair and reasonable per diem fee in addition to reimbursement of any expenses
incurred at the request of Presstek.

(f)      Without Presstek's express prior written consent, Employee will not
during his or her employment by Presstek engage in any employment or activity
other than for Presstek in any business in which Presstek is now or may
hereafter become engaged.

(g)      Employee agrees not to disclose to Presstek or use in any of his or her
work with Presstek any proprietary information of any of Employee's prior
employers or of any third party. Such information shall include, without
limitation, (i) any trade secrets or confidential information with respect to
the business, work or investigations of such prior employer or other third
party, or (ii) any ideas, inventions, improvements, innovations or discoveries
which do not constitute Workproduct as defined above. Employee further agrees
that if he or she is assigned to develop any Workproduct during the course of
his or her employment with Presstek where a question regarding the use of
proprietary information of others could be raised, then Employee shall
immediately inform his or her supervisor that continued work on such Workproduct
could raise a question as to the origin and ownership of such Workproduct and
request reassignment to another development project.

(h)      This Agreement shall apply to all Presstek confidential and proprietary
information, even where such information has been disclosed to Employee prior to
the execution of this Agreement and shall continue in full force and effect
until specific items of proprietary information covered by this Agreement either
become public knowledge or independently come into the possession of Employee in
a lawful manner unrelated to Employee's continued or previous employment with
Presstek.

<PAGE>

(i)      Upon termination of Employee's employment by Presstek, all Presstek
proprietary information and related materials released to Employee and all
materials prepared or created by Employee in connection with his or her
employment with Presstek, along with all copies and notes made thereof, in any
format or media, shall be returned promptly to Presstek along with a signed
certification that Employee has done so.

(j)      Employee represents that he or she has no agreements with or
obligations to others that conflict with the foregoing, or with Employee's
employment with Presstek generally.

This Agreement shall be construed in accordance with the laws of the State of
New Hampshire. This Agreement replaces any agreements previously signed by
Employee relating to Employee's employment by Presstek. This Agreement shall
inure to the benefit of the successors and assigns of Presstek, shall be binding
upon Employee's heirs, assigns and personal and legal representatives, and may
not be modified or terminated, in whole or part, except by a writing signed by
an authorized representative of Presstek. This Agreement shall not be deemed to
create an employment arrangement between Presstek and Employee.
