<PAGE>

and the declaration or ordering by the Commission of effectiveness of such

           (g) the term "Registrable Securities" shall mean, in relation to the
Holder at any particular time: (i) all shares of Common Stock issuable upon
conversion of the Preferred Stock held of record by the Holder at such time;
(ii) all shares of Common Stock held of record at such time by Holder as a

stock of the Company without the consent of the Holder.

           (h) the term "Rule 144" shall mean Rule 144 issued by the Commission
under the Securities Act, or any subsequent rule pertaining to the disposition
of securities without registration;

           (i) the term "Securities Act" shall mean the Securities Act of 1933,

           2.02. Registration on Form S-3. The Company will use its best efforts
in good faith to register the Registrable Securities on Form S-3 by February 9,
2002 (regardless of the number of times transfer of such shares is made on the
stock transfer books maintained by or for the Company, and regardless of the
number of certificates which may be issued to evidence such shares, and
irrespective of any subsequent transfer of or the disposition of such shares to
any other holder) (the "Registration Period"). To the extent not unlawful, the
Company will pay all Registration Expenses of each registration of Registrable
Securities pursuant to this Section 2.02. If the Company has not registered the
Registrable Securities by the end of the Registration Period or if the
Registration Statement is not effective at the end of the Permitted Suspension
Period (as hereinafter defined), the Company shall pay to the Holder one percent
(1.0%) of the aggregate purchase price paid by such Holder for the Preferred
Stock for each month that the Registrable Securities are not registered, which
amount shall be pro-rated for partial months, until the earlier of the
registration of the Registrable Securities and the date the Registrable
Securities are eligible for sale under Rule 144, provided, however, the Company
shall not be required to make such payment if the Company's failure to register
the Registrable Securities is due, in whole or in part, to the Holder's failure
to comply with Section 2.04 hereof.

           2.03. Registration Procedures. When the Company undertakes to effect
a registration pursuant to Section 2.02 hereof of the Registrable Securities,
the Company will use its best efforts in good faith to effect promptly the
registration of such Registrable Securities under the Securities Act and to
permit the public offering and sale of such Registrable Securities in

                                       2
<PAGE>

accordance with the intended method of disposition thereof, and, in connection
therewith, the Company, as expeditiously as shall be reasonably possible, will:

           (a) prepare and file with the Commission a registration statement
with respect to such Registrable Securities, and use its best efforts in good
faith to cause such registration statement to become and remain effective as
provided herein;

           (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus included in such
registration statement as may be necessary or advisable to comply in all
material respects with the provisions of the Securities Act with respect to the
disposition of all securities covered by such registration statement or as may
be necessary to keep such registration statement effective and current, but for
no longer than one (1) year subsequent to the effective date of such
registration;

           (c) furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto (in
each case including all exhibits thereto), the prospectus included in such
registration statement (including each preliminary prospectus), and such other
documents as any such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities held by such seller;

           (d) enter into such customary agreements and take all such other
customary action in connection therewith in order to expedite or facilitate the
disposition of such Registrable Securities; and

           (e) use its best efforts in good faith to register and qualify the
Registrable Securities covered by such registration statement under such
securities or Blue Sky laws of such jurisdictions as any seller shall reasonably
request and do any and all such other acts and things as may be reasonably
necessary or advisable to enable such seller to consummate the disposition in
such jurisdictions of the Registrable Securities held by such seller; provided,
however that the Company shall not be required in connection therewith to
qualify to do business or file a general consent to service of process in any
such jurisdiction.

           (f) notwithstanding the foregoing, if at any time or from time to
time after the date of effectiveness of the registration statement, the Company
notifies the Holder in writing of the existence of a Potential Material Event,
the Holder shall not offer or sell any Registrable Securities, or engage in any
other transaction involving or relating to the Registrable Securities, from the
time of the giving of notice with respect to a Potential Material Event until
such Holder receives written notice from the Company that such Potential
Material Event either has been disclosed to the public or no longer constitutes
a Potential Material Event; provided, however, that the Company may not so
suspend the right to such Holder of Registrable Securities for more than twenty
(20) business day periods in the aggregate during any 12-month period with at
least a ten (10) business day interval between such periods, during the periods
the registration statement is required to be in effect ("Permitted Suspension
Period");

           "Potential Material Event" shall mean any of the following: (i) the
possession by the Company of material information not ripe for disclosure in a
registration statement, which shall

                                       3
<PAGE>

be evidenced by determination in good faith by the Board of Directors of the
Company that disclosure of such information in the registration statement would
be detrimental to the business and affairs of the Company; or (ii) any material
engagement or activity by the Company which would, in the good faith
determination of the Board of Directors of the Company, be adversely affected by
disclosure in a registration statement at such time, which determination shall
be accompanied by a good faith determination by the Board of Directors of the
Company that the registration statement would be materially misleading absent
the inclusion of such information.

           2.04. Cooperation by Prospective Sellers, etc.

           (a) The Holder will furnish to the Company in writing such
information as the Company may reasonably require from the Holder or as required
by the Commission, and otherwise reasonably cooperate with the Company in
connection with any registration statement with respect to such Registrable
Securities.

           (b) The Holder of Registrable Securities included in any registration
statement will not (until further notice) effect sales thereof after receipt of
telegraphic or written notice from the Company to suspend sales to permit the
Company to correct or update such registration statement or prospectus.

           2.05. Registration Expenses.

           (a) The following costs and expenses incurred or sustained in
connection with or arising out of each registration pursuant to Section 2.02
shall constitute "Registration Expenses": all registration and filing fees, fees
and expenses of compliance with securities or Blue Sky laws, printing expenses,
messenger, telephone and delivery expenses, fees and disbursements of counsel
for the Company, fees and disbursements of all independent certified public
accountants (including the expenses relating to the preparation and delivery of
any special audit or "cold comfort" letters required by or incident to such
registration), and fees and disbursements of underwriters (excluding discounts
and commissions), the reasonable fees and expenses of any special experts
retained by the Company of its own initiative or at the request of the managing
underwriters in connection with such registration, and fees and expenses of all
(if any) other persons retained by the Company. The term "Registration Expenses"
shall not include, however, any legal fees or disbursements of counsel for the
Holder of Registrable Securities.

           (b) To the extent that Registration Expenses incident to any
registration are, under the terms of this Article II, not required to be paid by
the Company, each Holder of Registrable Securities included in such registration
will pay all Registration Expenses which are clearly solely attributable to the
registration of such Holder's Registrable Securities so included in such
registration, and all other Registration Expenses not so attributable to one
Holder will be borne and paid by all sellers of securities included in such
registration in proportion to the number of securities so included by each such
seller.

           2.06. Indemnification.

           (a) Indemnification by the Company. The Company will indemnify the
Holder, the officers, directors and partners of each such Holder and each person
who controls any thereof (within the meaning of the Securities Act), against any
and all claims, losses, damages and liabilities (or actions in respect thereof)
arising out of or based on any untrue statement (or alleged untrue statement) of
any material fact contained in any prospectus, offering circular or other
document incident to any registration, qualification or compliance (or in any
related registration statement, notification or the like) or any omission (or
alleged omission) to state therein any material fact required to be stated
therein or necessary to make the statements therein not misleading, or any
violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company and relating to any action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and the Company will reimburse each such Holder, officer,
director, partner and controlling person for any legal and any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action; provided, however, that the Company
will not be liable in any such case to the extent that any such claim, loss,
damage or liability arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company in an
instrument duly executed by such Holder, officer, director, partner or
controlling person and stated to be exclusively and specifically for use
therein.

           (b) Indemnification by the Holder. The Holder will indemnify the
Company and its officers and directors and each person, if any, who controls any
thereof (within the meaning of the Securities Act) and, if required by the
underwriter effecting the related registration, such underwriter, and their
respective successors in title and assigns against any and all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of any material fact
contained in any prospectus, offering circular or other document incident to any
registration, qualification or compliance (or in any related registration
statement, notification or the like) or any omission (or alleged omission) to
state therein any material fact required to be stated therein or necessary to
make the statement therein not misleading, and the Holder will reimburse the
Company and each other person indemnified pursuant to this paragraph (b) for any
legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action.

           (c) Indemnification Proceedings. Each party entitled to
indemnification pursuant to this Section 2.06 (the indemnified party) shall give
notice to the party required to provide indemnification pursuant to this Section
2.06 (the indemnifying party) promptly after such indemnified party acquires
actual knowledge of any claim as to which indemnity may be sought, and shall
permit the indemnifying party (at its expense) to assume the defense of any
claim or any litigation resulting therefrom; provided that counsel for the
indemnifying party, who shall conduct the defense of such claim or litigation,
shall be acceptable to the indemnified party, and the indemnified party may
participate in such defense at such party's expense; and provided, further, that
the failure by any indemnified party to give notice as provided in this
paragraph (c) shall not relieve the indemnifying party of its obligations under
this Section 2.06 except to the extent that the failure results in a failure of
actual notice to the indemnifying party and such

                                       5
<PAGE>

indemnifying party is damaged solely as a result of the failure to give notice.
No indemnifying party, in the defense of any such claim or litigation, shall,
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation. The
reimbursement required by this Section 2.06 shall be made by periodic payments
during the course of the investigation or defense, as and when bills are
received or expenses incurred.

           2.07. Rule 144 Requirements. The Company make publicly available and
available to the Holder of Registrable Securities, pursuant to Rule 144 of the
Commission under the Securities Act, such information as shall be necessary to
enable the Holders of Registrable Securities to make sales of Registrable
Securities pursuant to that Rule. The Company will furnish to any Holder of
Registrable Securities, upon request made by such Holder at any time, a written
statement signed by the Company, addressed to such Holder, describing briefly
the action the Company has taken or proposes to take to comply with the current
public information requirements of Rule 144. The Company will, at the request of
any Holder of Registrable Securities, upon receipt from such Holder of a
certificate certifying (i) that such Holder has held such Registrable Securities
for a period of not less than one (1) year, (ii) that such Holder has not been
an affiliate (as defined in Rule 144) of the Company for more than the ninety
(90) preceding days, and (iii) as to such other matters as may be appropriate in
accordance with such Rule, remove from the stock certificates representing such
Registrable Securities that portion of any restrictive legend which relates to
the registration provisions of the Securities Act, provided, however, in the
event that Foley, Hoag & Eliot LLP is no longer counsel to Company, counsel to
Holder may provide such instructions to the transfer agent regarding the removal
of the restrictive legend.

           2.08. Miscellaneous.

           (a) No Inconsistent Agreements. The Company will not, at any time
after the date of the Subscription Agreement, enter into any agreement or
contract (whether written or oral) with respect to any of its securities which
prevents the Company from complying in any respect with the registration rights
granted by the Company to the Holder of Registrable Securities pursuant to
Article II of this Agreement.

           (b) Amendments and Waivers. The provisions of Article II of this
Agreement, including the provisions of this paragraph (b), may not be amended,

of the provisions of Article II of this Agreement may not be given and shall not
become or be effective, unless and until (in each case) the Company shall have

for any such amendment, modification, supplement, waiver or consent.

Section shall be subject to all quality assurance and inspection requirements in
accordance with the provisions hereof.

                  d. Source Verification. XEROX shall have the right to conduct,
at its expense, source verification activities, in accordance with the PRESSTEK
Quality Assurance Procedures set forth in Exhibit H at PRESSTEK and third party
manufacturing sites for Products. XEROX must provide notification of intent to
perform a source verification to PRESSTEK a minimum of 2 weeks prior to the

verification date by month, quarter, biannually or annually. PRESSTEK shall have
the right to attend all source verifications at its manufacturers' location(s).
All source verifications will be conducted and reported based on the acceptance
inspection criteria set forth in this Section and Exhibit H.

         11. ORDERING/FORECAST PROCEDURE. The parties shall follow the following
ordering and payment procedure with regard to Products.

                  a. Purchase Orders. XEROX shall provide PRESSTEK a rolling
forecast for [CONFIDENTIAL TREATMENT REQUESTED]/*/ Press shipment requirements,
with the [CONFIDENTIAL TREATMENT REQUESTED]/*/ representing firm, noncancelable
orders and the balance of the forecast consisting of non-binding information
provided for planning purposes only except as expressly further set forth in
this Section. Changes to this [CONFIDENTIAL TREATMENT REQUESTED]/*/ forecast may
be submitted [CONFIDENTIAL TREATMENT REQUESTED]/*/ to PRESSTEK in which
[CONFIDENTIAL TREATMENT REQUESTED]/*/ may be increased or decreased by
[CONFIDENTIAL TREATMENT REQUESTED]/*/% and [CONFIDENTIAL TREATMENT REQUESTED]/*/
and beyond may be reduced by up to [CONFIDENTIAL TREATMENT REQUESTED]/*/% or
increased up to manufacturing line capacity(currently [CONFIDENTIAL TREATMENT
REQUESTED]/*/ units per month). PRESSTEK will make every effort to accommodate
requested [CONFIDENTIAL TREATMENT REQUESTED]/*/ shipment increases that have
less than [CONFIDENTIAL TREATMENT REQUESTED]/*/ notification. XEROX will submit
a new order/forecast outlining the next [CONFIDENTIAL TREATMENT REQUESTED]/*/
Press shipment requirements on or before the [CONFIDENTIAL TREATMENT
REQUESTED]/*/ of each month. Each such forecast/order shall specify the Presses
and features desired and the quantity and month of delivery requested. For the
[CONFIDENTIAL TREATMENT REQUESTED]/*/ of the forecast period, XEROX will
designate the Press with adequate specificity so that the Press can be fully
manufactured [CONFIDENTIAL TREATMENT REQUESTED]/*/; the forecast for the next
[CONFIDENTIAL TREATMENT REQUESTED]/*/ of the forecast period shall be in
adequate detail to order parts and components for the manufacture of such
Presses; and the forecast for the last [CONFIDENTIAL TREATMENT REQUESTED]/*/ of
the forecast period shall be sufficient for the ordering of long-lead time parts
and components for such Presses. The parties shall cooperate fully with one
another in the formulation of such descriptions.

                  b. Shipment Releases. A shipment release document, which
specifies the shipping address of Presses ordered, is required by the
[CONFIDENTIAL TREATMENT REQUESTED]/*/ of the requested shipping month. If XEROX
fails to provide shipment releases for Presses which are the subject of firm
orders pursuant to this Subsection by the end of the month during which the
Presses are scheduled for shipment, PRESSTEK may ship such Presses to a default
address or consign the Presses to an isolated location at the manufacturing
facility or to a bonded warehouse and invoice XEROX for the final payment for
such Presses. Payment for such Presses shall be due pursuant to the payment
terms of this Amended Agreement from the date of XEROX' receipt of correct
invoice without regard to the actual date of shipment. Such products shall be
stored in a facility agreed to between the parties, [CONFIDENTIAL TREATMENT
REQUESTED]/*/.

<PAGE>

                  c. Payments for Presses. All payments are due following XEROX'
receipt of a correct invoice, subject to the provisions of Section 7(n). To the
extent PRESSTEK has not received payment when due, PRESSTEK may suspend its
obligations to manufacture and deliver the Press for which payment is due but
not received.

                  d. Anything in this Section to the contrary notwithstanding,
PRESSTEK shall not be deemed in breach of its obligations to deliver Presses
pursuant to this Amended Agreement if PRESSTEK is prevented from doing so by
reason of any circumstance or occurrence constituting force majeure pursuant to
the terms of Section 36 of this Agreement.

12.      WARRANTY.

                  a. Products/Parts. Upon delivery of each Press pursuant to

PRESSTEK shall provide to XEROX kits containing the necessary software or
hardware to correct the Systemic Defect for all affected units of Product(s) or,
if XEROX reasonably believes it is probable that the Systemic Defect will affect
at least substantially all units of Product(s) then located either at customer
locations or in XEROX' inventory, PRESSTEK shall provide at its' expense XEROX
with the kits for all such units of Product(s).

                  e. Warranty Obligations. During the applicable warranty
periods set forth herein, the liability of PRESSTEK under the warranty set forth

failure to provide and maintain a suitable installation environment, with all
facilities prescribed by the appropriate specifications therefor (including, but
not limited to, failure of, or failure to provide, adequate electrical power,
air conditioning or humidity control) or from use of supplies or materials not
meeting such specifications; the use of the Presses for other than the purposes
for which they were designed; service of Presses or components which have been
modified, removed, installed or re-installed by someone other than PRESSTEK's
support personnel or its authorized representatives (including without
limitation XEROX); the Press has not been properly installed, used, and
maintained in accordance with the operating instructions and maintenance manuals
supplied by PRESSTEK; XEROX' failure to notify PRESSTEK in writing during the
warranty period with details on any defect or error in the Product; the Product
has been modified, changed, repaired, reconfigured or adapted in any manner
whatsoever without the express written consent of PRESSTEK; and evidence of
physical abuse or other catastrophic causes external to the Press has occurred
resulting in the necessity for repair or replacements, to the extent the
foregoing is not caused by PRESSTEK, its representatives, agents and/or
independent contractors.

                  g. New Warranties. All Product(s) repaired or replaced by
PRESSTEK under this Section shall be subject to XEROX' inspection and acceptance

PURPOSE, AND SUCH WARRANTY CONSTITUTES THE ONLY WARRANTY MADE BY PRESSTEK WITH
RESPECT TO THIS AMENDED AGREEMENT OR THE PRODUCT TO BE SUPPLIED HEREBY.

         13. EXCLUSIVITY. Provided XEROX meets the threshold purchase volumes of

marketing and sales right in [CONFIDENTIAL TREATMENT REQUESTED]/*/ to purchase
and resell the PAX Press and associated Consumables, and PRESSTEK shall not
distribute the PAX Press itself or through any third party, including without
limitation the third party manufacturer, during the period of such exclusivity.

within which it intends to conduct marketing, sales and distribution on an

         During any period in which Xerox has the exclusive rights set forth
above, XEROX shall have semi-exclusive rights for co-marketing, co-selling and
co-distributing the PAX press outside of [CONFIDENTIAL TREATMENT REQUESTED]/*/
and [CONFIDENTIAL TREATMENT REQUESTED]/*/.

         If XEROX fails to meet the threshold purchase volumes for new Presses
(above the early customer configuration units) established pursuant to this
Section (except as a result of PRESSTEK's failure to deliver ordered Presses
which comply with the applicable Specifications or to otherwise comply with its
obligations hereunder), then PRESSTEK shall have the right to terminate the
exclusivity of XEROX' marketing and sales right and to convert it to a worldwide
semi-exclusive marketing and sales right upon written notice to XEROX.
[CONFIDENTIAL TREATMENT REQUESTED]/*/

                  a. PAX Press Purchase Threshold. In order to obtain the
exclusive marketing and sales right with respect to the PAX Press and associated
Consumables, XEROX must purchase from PRESSTEK [CONFIDENTIAL TREATMENT
REQUESTED]/*/ PAX Presses in the [CONFIDENTIAL TREATMENT REQUESTED]/*/ period
commencing on the date of first commercial shipment of Presses (beyond the early
customer configuration units). To maintain its exclusive marketing and sales
right for subsequent [CONFIDENTIAL TREATMENT REQUESTED]/*/ periods, XEROX shall
purchase at least [CONFIDENTIAL TREATMENT REQUESTED]/*/ PAX Presses during each
such subsequent [CONFIDENTIAL TREATMENT REQUESTED]/*/ period. The parties shall
negotiate in good faith and mutually agree as to what these threshold volumes
will be in the fourth quarter of each year. If by the end of the [CONFIDENTIAL
TREATMENT REQUESTED]/*/ of any [CONFIDENTIAL TREATMENT REQUESTED]/*/ period, the
total number of PAX Presses purchased and forecast for purchase for the
remainder of that [CONFIDENTIAL TREATMENT REQUESTED]/*/ period falls below the
annual threshold of PAX Presses for exclusivity threshold for any [CONFIDENTIAL
TREATMENT REQUESTED]/*/ period, or if XEROX fails to purchase at least
[CONFIDENTIAL TREATMENT REQUESTED]/*/ percent of the annual threshold of PAX
Presses for any [CONFIDENTIAL TREATMENT REQUESTED]/*/ period for each of
[CONFIDENTIAL TREATMENT REQUESTED]/*/, and such failure is not due either to
PRESSTEK's breach or a force majeure event, then PRESSTEK may, in its
discretion, terminate XEROX' exclusivity for the PAX Press upon written notice
to XEROX and render the distribution rights granted herein to the PAX Press to
be [CONFIDENTIAL TREATMENT REQUESTED]/*/.

To maintain its [CONFIDENTIAL TREATMENT REQUESTED]/*/ marketing and sales right
with respect to the PAX Press and its associated Consumables, XEROX must
purchase from PRESSTEK [CONFIDENTIAL TREATMENT REQUESTED]/*/ PAX Presses in the
[CONFIDENTIAL TREATMENT REQUESTED]/*/ period commencing on the expiration of
exclusivity period. To maintain its [CONFIDENTIAL TREATMENT REQUESTED]/*/
marketing and sales right for subsequent [CONFIDENTIAL TREATMENT REQUESTED]/*/
periods, XEROX purchases of PAX Presses shall be at least [CONFIDENTIAL
TREATMENT REQUESTED]/*/ PAX Presses during each such [CONFIDENTIAL TREATMENT
REQUESTED]/*/ period. The parties shall negotiate in good faith and mutually
agree as to what these threshold volumes will be in the [CONFIDENTIAL TREATMENT
REQUESTED]/*/ of each [CONFIDENTIAL TREATMENT REQUESTED]/*/. If by the end of
the [CONFIDENTIAL TREATMENT REQUESTED]/*/ of any [CONFIDENTIAL TREATMENT
REQUESTED]/*/ period, the total number of PAX Presses purchased and ordered for
the remainder of that period falls below the annual threshold for that
[CONFIDENTIAL TREATMENT REQUESTED]/*/ period, or if XEROX fails to purchase at
least [CONFIDENTIAL TREATMENT REQUESTED]/*/ percent of the annual threshold for
that [CONFIDENTIAL TREATMENT REQUESTED]/*/ period for each of [CONFIDENTIAL
TREATMENT REQUESTED]/*/, and such failure is not due either to PRESSTEK's breach

rights of semi-exclusivity upon written notice to XEROX and render the

operator manuals for the Products (in the English and other languages mutually
agreed) so that XEROX and XEROX Companies can, on a periodic basis and as new
changes or additions occur, make copies thereof and distribute the same to its
sales force and customers. During the term of this Agreement, XEROX and XEROX
Companies may also include Product(s) description and information in any XEROX
or XEROX Company literature. The distribution of such literature by XEROX and
XEROX Companies will be at their sole expense.

                  c. Escrow. With respect to software components of the
Products, the parties shall execute within thirty (30) days of the date of
execution hereof an Escrow Agreement in substantially the form of the Escrow
Agreement attached hereto as Exhibit I with a third-party escrow agent to permit

and thereafter remarketing of Product(s) by XEROX shall not be deemed nor
constitute a violation by XEROX of any of PRESSTEK's rights, including but not

to be conducted, within [CONFIDENTIAL TREATMENT REQUESTED]/*/ of receipt of such
request. Work will commence on PRESSTEK's receipt of a XEROX purchase order.
PRESSTEK will use commercially reasonable efforts to minimize costs and time of
such services. All costs including transport shall be borne by XEROX. Payment
shall be received by PRESSTEK within [CONFIDENTIAL TREATMENT REQUESTED]/*/ from
delivery of a correct invoice.

         18. [CONFIDENTIAL TREATMENT REQUESTED]/*/ COOPERATION. PRESSTEK will
use commercially reasonable efforts to cooperate with XEROX to support the
development of an appropriate [CONFIDENTIAL TREATMENT REQUESTED]/*/ interface

will agree in writing on a development schedule, budget, milestones and
deliverables, and proprietary rights with respect to any such development, with
mutually agreeable allocation of costs and expenses, before undertaking any
development work or commitment of resources.

         19. TECHNOLOGY IMPROVEMENTS. PRESSTEK will use reasonable commercial
efforts to provide engineering changes and/or improvements in the Presses upon

indemnify and hold XEROX, XEROX Companies, and their respective authorized
resellers, customers and officers, directors, employees and representatives
("Indemnities") harmless from any suit claim, demand, cause of action or
proceeding asserted by a third party against any of the indemnities alleging (i)
that any Product(s) violates any applicable safety or regulatory standard or has
caused personal injury (including death) or damage to property or (ii) the
infringement or misappropriation of such third party's intellectual property
rights (a "Claim"), provided that PRESSTEK is notified of the Claim by XEROX
within a reasonable time after XEROX learns of it, is given all reasonable
assistance by XEROX necessary for PRESSTEK to perform its obligations in respect
of the Claim and is given the sole right to control the defense and settlement
of the Claim.

                  b. Injunction; Disclaimer. Should the Products become, or in
PRESSTEK's opinion, be likely to become, the subject of a claim for infringement
under this section, PRESSTEK may (i) at its own expense and option, either
procure for XEROX the right to continue using such Subject Presses or replace
the same with non-infringing components having substantially equivalent features
and functionality, or modify the system so that it becomes non-infringing with
substantially equivalent features and functionality, or (ii) at XEROX' option,

payments received by PRESSTEK on the then aggregate depreciated value of the
Subject Press purchased under this Amended Agreement (after deducting the time
for XEROX' customers' use and operation of the Subject Press prior to the time
of any final determination of infringement against PRESSTEK). PRESSTEK shall not
be obligated to defend or be liable for costs and/or damages under this section
if the alleged infringement arises out of a combination with or an addition to
PRESSTEK's software or equipment of equipment, devices or software not supplied
by PRESSTEK or with PRESSTEK's knowledge and consent, or from a modification,
service or support of the equipment or software after delivery by any person
other than PRESSTEK and/or its representatives, agents and independent
contractors. XEROX shall have the option to procure continued use at its own
expense.

                  c. By XEROX. XEROX shall indemnify and hold PRESSTEK and its
officers, directors, employees and representatives harmless from all claims,
losses, and damages which may arise from XEROX' installation or support of the
Products, including claims of customers based on misrepresentations made by
XEROX, inadequate installation, support or assistance by XEROX. XEROX shall, at
its expense, indemnify, hold harmless and, at the PRESSTEK's request, defend
PRESSTEK and its manufacturers, from and against any and all loss, cost,
liability or expense (including costs and reasonable fees of attorneys and other
professionals) arising out of or in connection with XEROX' performance under
this Amended Agreement to the extent caused by any negligent act or omission or
willful misconduct of XEROX or XEROX' employees or independent contractors.

SALE AND DISTRIBUTION OF THE PRODUCTS.

         23.      TERM AND TERMINATION.

                  a. Term. The term of this Amended Agreement shall commence
upon the Effective Date and continue in full force and effect until
[CONFIDENTIAL TREATMENT REQUESTED]/*/. The parties agree that not less than 180
days prior to the expiration of any term or renewal term, either party may
notify the other party in writing of nonrenewal or, in the absence of such
notification, the parties agree to negotiate in good faith any modifications
and/or other terms and conditions for such renewal. The provisions of this
Section shall not apply to the sale of Spares, which shall be governed solely by
the provisions of Exhibit J.

                  b. Termination for Cause. In addition to XEROX' rights under
Section 11(e), either party may terminate this Amended Agreement, or any
Purchase Order issued under this Amended Agreement effective immediately upon
written notice of termination to the other party in any of the following events:

                           (i) If the other party materially breaches this
         Amended Agreement and such breach, if curable, is not cured within
         sixty (60) days after written notice of breach by the terminating
         party;

                           (ii) If the other party's performance is delayed for
         more than ninety (90) days for any reason, including Force Majeure
         delays; or

                           (iii) If a petition for relief under applicable
         bankruptcy regulations is filed by or against the other party, or the
         other party makes an assignment for the benefit of creditors, or a
         receiver is appointed to manage its assets, and such petition,
         assignment is not dismissed, vacated or terminated within ninety (90)
         days. To the extent applicable law prevents the non-terminating party
         from terminating this Amended Agreement as described above, then the
         parties shall have only those rights and remedies permitted by
         applicable law, including the United States Bankruptcy Act, including
         but not limited to 11 U.S.C. Section 365. Any such termination shall be
         automatically effective at the end of any applicable notice period if
         any.

                  c. Continuity of Supply. If XEROX is committed to supply
Product(s) to its customers beyond such termination or expiration date, PRESSTEK
and XEROX agree to negotiate in good faith, and in a timely manner, terms and
conditions to allow XEROX to fulfill such commitments. In the absence of
agreement as to such terms and conditions, the parties agree to submit such
dispute to arbitration as set forth in Section 33 hereof, and PRESSTEK shall
continue to deliver Products to XEROX during the pendency of such arbitration at
price levels which were in effect immediately prior to such termination or
expiration. The arbitration can result in a retroactive change of the aforesaid
price levels.

                  d. Liability Limitation. Except as otherwise set forth in this
Amended Agreement or with respect to obligations which survive its termination
or expiration (as

applicable), XEROX' sole liability to PRESSTEK shall be for the payment of any
balance due and owing for conforming Products delivered prior to the effective
date of termination or expiration or within the firm forecast period, and XEROX
shall have no further liability whatsoever hereunder, including without
limitation or inventory, raw materials, work in process, components, or any
other expenses or damages. In the event of any breach the nonbreaching party
reserves all rights to pursue any and all legal remedies available for such
breach subject to the terms hereof.

                  e. Continuity of Service. XEROX shall retain all rights and
documentation necessary to continue servicing Product(s) sold and/or licensed
hereunder prior to any breach and the right to dispose of its inventory of
Product(s), subject to all payment obligations to PRESSTEK.

                  f. Survival. Any termination of this Amended Agreement shall
not serve to eliminate any liability arising out of conduct prior to the actual
date of termination, including any uncontested accrued payment obligation, and
either party may, following such termination, pursue such remedies as may be
available with respect to such liabilities. Any and all such payments accrued
hereunder as of the date of termination shall remain due and payable in
accordance with the terms hereof. Termination of this Amended Agreement shall
immediately terminate all licenses hereunder to the software or firmware within
the Presses, except for licenses to the software or firmware for Presses which
have been previously paid for by XEROX or Presses previously sold to customers.

         24. Compliance with Laws. PRESSTEK and its manufacturers shall comply
in all material respects with (a) any applicable governmental laws and
regulations (including without limitation the Federal Trade Commission's
Enforcement Policy Statement on U.S. Origin Claims (62 F.R. 63756 [December 2,
1997]); (b) applicable governmental environmental and safety regulations and
standards (without self-certification in European Union countries, where
independent third party certification shall be obtained); and (c) those XEROX
requirements which are set forth in the Specifications applicable to this
Amended Agreement and which are in effect at the time of shipment of all
Product(s) hereunder where such approval applies to PRESSTEK and its
manufacturers. From time to time it may be necessary for the parties to review
the Amended Agreement and update the information for current requirements.
PRESSTEK shall obtain, at no cost to XEROX, full Regulatory Agency approvals as
required for Product(s) in accordance with the schedules shown in the
Specification where such approval applies to PRESSTEK/its manufacturers.
PRESSTEK shall obtain, at no cost to XEROX, any required Regulatory Agency
reapprovals for any Product(s) which are modified in any authorized manner
hereunder.

         25. RELATIONSHIP OF THE PARTIES. Nothing contained in this Amended
Agreement shall be deemed to (a) make either party or any employee of such party
the agent, employee, joint venturer or partner of the other party; pr (b)
provide either party or any employee of such party with the power or authority
to act on behalf of the other party or to bind the other party to any contract,
agreement or arrangement with any other person. During the term of this

                                      -23-
<PAGE>

Agreement, if the term "partnership", "partner" or "development partner" or the
like is used to describe the parties' relationship, XEROX and PRESSTEK agree to
make it clear to third parties that these terms refer only to the spirit of
cooperation between them and neither describe, nor expressly or implicitly
create, the legal status of partners or joint venturers. All personnel employed
or otherwise engaged by either party shall be the agents, servants, and
employees of such party only, and the other party shall incur no obligations or
liabilities, express or implied, by reason of the conduct of such personnel.

         26. WAIVER. Waiver by either party hereto of any breach or default by
the other party if any of the terms and conditions of this Amended Agreement
shall not operate as a waiver of any other breach or default, whether similar to
or different from the breach or default waived.

         27. COSTS AND EXPENSES. Except as otherwise provided in this Agreement,
each party hereto shall be responsible for its own expenses incurred in
connection with the performance of its obligations under such agreements.

         28. ENTIRE AGREEMENT. This Agreement, together with all Exhibits,
represents the entire understanding and agreement between the parties hereto
with regard to the Products and supersedes all prior negotiations,
representations, and agreements made by and between the parties. No alteration,
amendment or modification of any of the terms or provisions of this Amended
Agreement shall be valid unless made pursuant to an instrument in writing signed
by each of the parties hereto; provided however, that the waiver by either party
hereto of compliance by the other party with any provision hereof or of any
breach or default of such other party need by signed only by the party waiving
such provision, breach or default.

         29. GOVERNING LAW. This Amended Agreement and the Confidentiality
Amended Agreement shall be governed by and interpreted in accordance with the
laws of the State of New York without regard to its conflict of laws principles.
Any action to enforce the terms of this Amended Agreement shall take place in
the courts located in the State of New York and the parties consent to the venue
and jurisdiction of such courts. The parties specifically agree that the 1980
United Nations Convention on Contracts for the International Sale of Goods, as
such may be amended from time to time, shall not apply to this Agreement. The
definitions set forth in the Incoterms of the International Chamber of Commerce,
2000 edition, shall be controlling.

         30. NON-ASSIGNMENT. A party to this Amended Agreement may not assign
its rights and obligations under this Amended Agreement without the consent of
the other party; provided, however, that each party may assign this Amended
Agreement in connection with (a) the sale of all or substantially all of the
capital stock or assets of such party, or (b) the acquisition by a third party
of a party to this Amended Agreement by merger, consolidation, reorganization or
other business combination whereby more than fifty (50) percent of the voting
securities of a party to this Amended Agreement are sold or transferred to a
third party (a "Business Combination"). Notwithstanding the foregoing, in the
event of a [CONFIDENTIAL TREATMENT REQUESTED]/*/, XEROX shall have the right to

and as further provided in Section 23(d). Both parties agree, however, that
PRESSTEK may delegate a portion of its obligations pursuant to this Amended
Agreement to its subcontractors and manufacturers, provided that PRESSTEX
contractually obligates and guarantees the performance of the foregoing and
indemnifies XEROX against any and all claims, losses, demands, causes of action
or other liability which may arise in connection with such delegation, subject
to the terms of this Agreement, including sections relating to warranty,
indemnity and limitation of liability.

or such other addresses either party shall hereinafter designate in writing to
the other party.

         32. INVALIDITY OF PROVISIONS. If any of the provisions of this Amended
Agreement shall contravene the laws of any country, it is agreed that such
invalidity or illegality shall not invalidate the whole agreement, but such
agreement shall be construed as if it did not

                                      -25-
<PAGE>

contain the provisions claimed or held to be invalid or illegal in the
particular jurisdiction concerned, insofar as such construction does not
materially affect the substance of such agreement, and the rights and
obligations of the parties hereto shall be construed and enforced accordingly.
In the event, however, that such claimed invalidity or illegality shall
substantially alter the relationship between the parties hereto materially
affecting adversely the interest of either party in such jurisdiction, then the
parties hereto shall negotiate an alternative provision not conflicting with
such laws so as to maintain, to the degree reasonably possible, the business and
economic benefits and liabilities of such agreement as initially established. If
such invalidity or illegibility is such that it is not possible to reasonably
restore the business and economic benefits and liabilities of the parties, then
the party whose interests are adversely affected shall have the right to
terminate that portion of this Amended Agreement as is materially impacted by
such invalidity or illegibility.

         33. ARBITRATION. In the event of any dispute, controversy or claim
arising out of, in connection with, or in relation to this Amended Agreement or
breach thereof, the parties shall attempt to resolve such matter by means of
mediation between and among the senior executives of PRESSTEK and XEROX. In the
event such mediation is unsuccessful after 60 days, then any such dispute,
controversy or claim arising out of, in connection with, or in relation to this
Amended Agreement or breach thereof (except for claims for which equitable
relief is sought or claims related to infringement) shall be settled by
arbitration in accordance with the rules of the American Arbitration Association
then in force. The parties agree to (i) appoint an arbitrator who is
knowledgeable in and familiar with the printing and imaging industry, and
instruct the arbitrator to follow substantive rules of law; (ii) require the
testimony to be transcribed; and (iii) require the award to be accompanied by
findings of fact and a statement of reasons for the decision. The arbitrator
shall have the authority to permit discovery, to the extent deemed appropriate
by the arbitrator, upon request of a party. The arbitrator shall have no power
or authority to add to or detract from the written agreement of the parties. All
costs and expenses, including attorneys' and the arbitrator's fees, of all
parties incurred in any dispute which is determined and/or settled by
arbitration pursuant to this section shall be borne equally by the parties..
Except where clearly prevented by the area of dispute, both parties agree to
continue performing their respective obligations under this Amended Agreement
while the dispute is being resolved. Any award shall be final, binding and
conclusive upon the parties and a judgment rendered thereon may be entered in
any court having jurisdiction thereof. This Section shall not limit the right of
any party to sue for injunctive relief, for a breach of the confidential
obligations under the Confidentiality Agreement, for indemnified matter or a
violation of the license rights granted herein. Arbitration shall be held in New
York, New York.

         34. Export Control. PRESSTEK and XEROX shall comply in all material
respects with all applicable laws and regulations respecting the export,
directly or indirectly, of any technical data acquired from the other under this
Amended Agreement or any Product(s) utilizing any such data to any country the
laws or regulations of which at the time of export, require an export license or
other government approval, including but not limited to first obtaining such
license or approval.

<PAGE>

         35. Nonpublicity. Neither party shall (a) make any news release, public
announcement, denial or confirmation of this Amended Agreement or its subject
matter, or (b) advertise or publish any facts relating to this Agreement,
without the prior written consent of the other party with respect to the content
of any of the foregoing, subject to applicable rules, policies, practices and
procedures of the Securities and Exchange Commission, National Association of
Securities Dealers, Inc., other authority or exchange applicable to either
party, or advice of counsel.

         36. FORCE MAJEURE. Neither party shall be liable or deemed to be in
default for any delay or failure in performance under this Amended Agreement or
interruption of services resulting directly or indirectly from acts of God,
allocation of parts and components due to civil or military authority, war,
riots, civil disturbances, accidents, fire, earthquakes, floods, strikes,
lock-outs, labor disturbances, foreign or governmental order, or any other cause
beyond the reasonable control of such party. The foregoing shall not apply to
any payment obligation of a party.

         37.      TAXES.

                  a. Prices do not include Taxes.

                  b. For purposes of this section, "Taxes" shall mean any and
all taxes, duties, and similar charges imposed or collected by any governmental
entity worldwide or any political subdivision thereof and however designated or
levied and shall include any interest, penalties, or additions to tax (except as
may otherwise be specifically provided herein). "Taxes" as defined herein shall,
however, expressly exclude taxes imposed upon the net income of PRESSTEK (or
similar taxes imposed in lieu of such net income taxes, including income
withholding taxes that are required to be collected by XEROX on amounts due to
PRESSTEK).

                  c. If PRESSTEK is required to pay any sales, value added, use,
excise, import-related or other Taxes (whether federal, state, local, or
foreign) imposed with respect to the transactions contemplated by this Amended
Agreement or any license granted hereunder, such Taxes shall be paid by XEROX
(1) through remittance to PRESSTEK which shall remit such Taxes to the
appropriate taxing authority, or (2) to the applicable taxing authority, the
manner and timing of such payment to depend on the context as appropriate. In
lieu of such Tax payment, and where applicable, XEROX may provide PRESSTEK with
a Tax exemption certificate and any other appropriate documentation acceptable
to the appropriate taxing authority as provided in subsection (f) below or as
mutually agreed between the parties.

                  d. Any invoice on which Taxes are added to the price by
PRESSTEK shall separately state any and all such Taxes. Such original invoice
shall be supported by appropriate detail and summary billing information
provided to XEROX in a timely manner, and both the invoice and the supporting
documentation shall be in the form required by the appropriate governmental
agency or as otherwise mutually agreed.

                                      -27-
<PAGE>

                  e. PRESSTEK shall indemnify XEROX for: (i) Taxes paid by XEROX
to PRESSTEK imposed as a result of PRESSTEK's failure to remit such Taxes paid
by XEROX to PRESSTEK to the appropriate taxing jurisdiction in a timely fashion
after their receipt; (ii) any Taxes in excess of the amount of Tax which would
have been charged if the original invoice had been correct (less the interest
benefit realized by XEROX due to the time value of money relating to the delay
in payment of such Tax) relating solely to PRESSTEK's failure attributable to
its actions or inaction (except as commercially reasonable) to invoice XEROX for
the correct amount of Taxes at the time of the original invoice; and (iii) any
Tax arising from PRESSTEK'S purchase of Products that are acquired by PRESSTEK
to be resold to XEROX under this Agreement.

                  f. PRESSTEK and XEROX agree to cooperate to minimize and
properly calculate any applicable Taxes for which either party is responsible
under this Agreement, and, in connection therewith, XEROX shall provide PRESSTEK
any resale certificates, information regarding out-of-state use of materials,
services or sales or other exemption or tax reduction certificates or other
certificate or document of exemption or information that may be required in
order to exempt XEROX'S payment for goods and/or services from any such Taxes,
and PRESSTEK shall cooperate to the extent commercially reasonable in accepting
and supporting any claims (which XEROX in good faith deems to be valid) of
resale, direct pay, identifiable segment, bulk sale, occasional sale, casual
sale or other exemption. If XEROX provides certification of an exemption from
any Tax or of a reduced rate of Tax imposed by an applicable taxing authority,
under such taxing authority's rules, then PRESSTEK shall not (unless otherwise
required by law) invoice for or pay over any such Tax unless and until the
applicable taxing authority assesses such Tax, at which time PRESSTEK shall
invoice and XEROX shall pay any such Tax that XEROX erroneously claimed
exemption of or a reduced rate.

                  g. Subject to the provisions in the last sentence of
subsection (j) hereof, XEROX shall be entitled to, and PRESSTEK shall promptly
repay to XEROX if received by PRESSTEK, any refunds, rebates or credits of Taxes
paid by XEROX pursuant to this Agreement, together with interest thereon as paid
by the applicable taxing authority.

                  h. If PRESSTEK receives any assessment or other notice
(collectively "Assessment") from any taxing authority providing that Taxes are
due from PRESSTEK which are subject to payment by or indemnification from XEROX
pursuant to this Agreement, PRESSTEK shall, within thirty (30) days of receipt
of the Assessment, give XEROX written notice of the Assessment and XEROX shall
pay to PRESSTEK or directly to the taxing authority the amount of Taxes set
forth as due in the Assessment within thirty (30) days of receipt of such notice
or such shorter period as is reasonable to protect the right of protest or
appeal or other material rights; exclusive, however, of any amounts for which
PRESSTEK has indemnified XEROX in accordance with this Agreement.
Notwithstanding the above, if XEROX, in its sole discretion, determines that it
will contest an Assessment of indemnifiable Taxes rather than make a payment to
PRESSTEK or the applicable governmental taxing authority, then XEROX shall
control any such contest and PRESSTEK shall, to the extent commercially
reasonable under the circumstances, cooperate with XEROX in such contest and
provide such support, information, documents and other items that may be
reasonably beneficial to XEROX in its contest of any

                                      -28-
<PAGE>

such Assessment. In any case where XEROX determines to contest an Assessment,
XEROX will fully indemnify PRESSTEK for Taxes and other reasonable defense costs
related thereto incurred by PRESSTEK as a result of the contest. If any such
contest or resolution thereof could reasonably be expected to have a material
effect on PRESSTEK, PRESSTEK shall have reasonable rights to participate in such
contest or resolution and to approve any settlement or other resolution, which
approval shall not be unreasonably withheld. If PRESSTEK determines that it
would prefer that XEROX not contest an Assessment, PRESSTEK may notify XEROX at
any time not to pursue such contest, provided that PRESSTEK fully satisfies any
such Assessment. In such a case, XEROX will have no obligation to indemnify
PRESSTEK for any amounts paid or payable by PRESSTEK with respect to such
Assessment.

                  i. In accordance with the definition of Taxes set out in
subsection (b) hereof, to the extent royalties are payable to PRESSTEK and any
amounts paid to PRESSTEK (or to XEROX on PRESSTEK's behalf) in respect of such
royalties are subject to income withholding taxes, such withholding taxes shall
be considered to be based upon PRESSTEK's net income. Accordingly, payments to
PRESSTEK in respect of such royalties shall be made net of such withholding
taxes, and XEROX shall have no obligation to indemnify PRESSTEK for any such
withholding taxes. XEROX shall promptly furnish to PRESSTEK receipts evidencing
the payment of any such withholding taxes. If PRESSTEK provides certification of
an exemption from any tax or of a reduced rate of tax imposed by an applicable
taxing authority, under the rules of such taxing authority, then XEROX shall not
(unless otherwise required by law) invoice for or pay over any such tax unless
and until the applicable taxing authority assesses such tax, at which time XEROX
shall invoice and PRESSTEK shall pay any such tax (plus any applicable interest,
penalties, or additions to tax) that PRESSTEK erroneously claimed exemption of
or a reduced rate.

                  j. XEROX shall indemnify PRESSTEK for any Taxes for which
XEROX bears responsibility under this Agreement, to the extent if any, that the
sum of payments and or reimbursements for Taxes made by XEROX either to PRESSTEK
or directly to taxing authorities does not fully equal the amount of Taxes that
PRESSTEK is required to pay as provided in this section 37. To the extent that
any Taxes payable by PRESSTEK that have been or would be subject to payment,
reimbursement, or indemnification by or from XEROX under this Amended Agreement
are eligible for a tax credit or rebate to PRESSTEK, PRESSTEK will either pay
over such credit or rebate to XEROX (if XEROX has already paid such amount to
PRESSTEK) or will not pursue reimbursement or indemnification from XEROX, as the
case may be, provided that claiming such rebate or credit and passing the
benefit thereof to XEROX will not have any material adverse tax or other effect
(relative to the amount of the credit or rebate) upon PRESSTEK and that XEROX
pays the reasonable expenses to obtain such credit or refund.

         38. COUNTERPARTS. This Amended Agreement may be signed in counterparts
and each counterpart shall be considered an original document.

                            - PLATE SPECIFICATIONS -

PRODUCT NAME: Presstek PEARLdry PLUS thermal laser media - spooled product.

PRODUCT DESCRIPTION: Metalized polyester film with silicone coating.

PRODUCT APPLICATION: Plate material for Presstek DI enabled printing presses.
The material is spooled on steel cores that engage unwind and take-up mechanisms
integral to the press plate cylinder. The design allows a specific amount of
material to be advanced into imaging and printing position. A thermal laser
imaging system creates a latent image on the surface of the plate. A subsequent
cleaning step removes silicone in the imaged areas, creating an ink-receptive
printing master. Up to [CONFIDENTIAL TREATMENT REQUESTED]/*/* copies can be
produced from the printing master.

* Actual run length performance may vary.

                          SOURCE CODE ESCROW AGREEMENT

     This SOURCE CODE ESCROW AGREEMENT is entered into by and among DATA
SECURITIES INTERNATIONAL, INC. with offices ___________________________________
("DSI" or "HOLDER"); PRESSTEK, INC., a Delaware corporation ("LICENSOR"), with
offices at 9 Commercial Street, Hudson, New Hampshire 03051; and Xerox
Corporation, located at ______________________ (the "LICENSEE" or "LICENSEE").

                                    RECITALS

A.   Licensor and Licensee have entered or will enter into certain Master Supply
and Distribution Agreement involving the production of Presses certain
proprietary software or firmware technology of Licensor (referred to in this
Agreement as the "MASTER AGREEMENT").

B.   Licensor desires to avoid unauthorized use or disclosure of its proprietary
technology except under certain limited circumstances as defined herein.

C.   The availability of the proprietary technology of Licensor is critical to
Licensee in the conduct of its business and, therefore, Licensee needs access to
the source code materials and other proprietary technology of Licensor under
certain limited circumstances if Licensor shall fail to maintain and support the
software described in the Master Agreement, or should Licensor experience
financial difficulties by becoming subject to bankruptcy or insolvency
proceedings, as defined herein.

D.   Licensor and Licensee desire to establish an escrow with DSI to provide for
the retention, administration and controlled access of certain proprietary
technology materials of Licensor.

E.   The parties desire this Agreement to be supplementary to the Master
Agreement pursuant to 11 United States Bankruptcy Code, Section 365(n). This
Agreement is entered into in furtherance of the provisions and objectives of
that certain Master Agreement.

     For valuable consideration acknowledged by each, the parties agree that:

1.   DEPOSIT. Licensor shall deposit with Holder those source code materials
     specified in EXHIBIT I-1 (the "Deposit"). Licensor shall keep the Deposit
     at the current revision level on an annual basis commencing with the
     effective date of this Agreement. In addition, Licensor shall update the
     Deposit at any time during the term or any renewal term of this Agreement
     that Licensor issues a new, material version or release of the Deposit.
     Licensor also agrees to comply with Holder's reasonable requests for the
     deposit or replacement of Deposit materials likely to physically degrade.

2.   RETENTION OF REPLACED DEPOSIT. Holder will also retain all existing and
     supplanted Deposit materials for the benefit of Licensee and Licensor.

3.   VERIFICATION AND DELIVERY. The Deposit shall be packaged for storage as
     reasonably instructed by Holder and accompanied by a cover sheet
     identifying the contents as indicated in EXHIBIT I-1. Risk of loss or
     damage to the Deposit materials during shipment shall lie with the

                                  PAGE 1 OF 10
<PAGE>
     Licensor. Licensee shall have the right to verify, at its own expense, each
     Deposit before shipment at Licensor's premises.

     Licensor hereby grants Licensee and Holder, free of charge, at its own
     expense, the right to use the facilities of Licensor, including its
     computer systems, to as reasonably necessary to verify the Deposit. Such
     right shall be exercised by 30 days' prior written notice from Licensee to
     Licensor and inspection will occur during Licensor's normal business hours
     without undue disruption of Licensor's business. At the expense of
     Licensor, Licensor shall make available Licensor's technical support
     personnel as reasonably necessary to verify the Deposit.

4.   STORAGE OF DEPOSIT. Holder shall safekeep the Deposit in a security vault
     and exercise the same high standard of care to protect the Deposit which
     Holder would use to protect items of this nature which Holder might own,
     but in no event less than that standard of care customary in the industry.

5.   USE AND NONDISCLOSURE. Except as expressly provided in this Agreement,
     Holder shall not disclose or make any use whatsoever of the Deposit, nor
     shall Holder disclose or make use of any confidential information provided
     to Holder by Licensor or Licensee in connection with this Agreement without
     the prior written consent of Licensor or Licensee, respectively. These
     obligations shall continue indefinitely notwithstanding any termination of
     this Agreement for any reason.

6.   RECORDS AND AUDIT RIGHTS. Holder shall keep complete written records of the
     activities undertaken and materials prepared pursuant to this Agreement.
     Upon 10 days prior written notice to Holder during the term of this
     Agreement, Licensor and Licensee shall be entitled to inspect and request
     the records of Holder with respect to this Agreement at reasonable times
     during normal business hours at Holder's facilities and to inspect the
     Deposit required then to be held by Holder.

7.   RELEASE OF DEPOSIT. If Licensee notifies Holder of the occurrence of a
     release condition as defined in EXHIBIT I-2, Holder shall immediately
     notify Licensor and provide Licensor with a copy of the notice from
     Licensee. Licensor shall have ten (10) business days from the date Holder
     sends its notice to notify Holder and Licensee that the release condition
     has not occurred or has been cured. Failing such timely notice, Holder
     shall release a copy of the Deposit to Licensee. However, if Holder
     receives timely notice from Licensor, Holder shall not release a copy of
     the Deposit but shall instead institute the Dispute Resolution Process
     below within three (3) business days of such timely notice from Licensor.

8.   DISPUTE RESOLUTION PROCESS. Holder shall first notify Licensor and Licensee
     in writing of contrary instructions from Licensee and Licensor for release
     of the Deposit. Within five (5) business days after the date the notice is
     sent by Holder, an independent referee shall be appointed by the mutual
     agreement of Licensor and Licensee.

     On the 20th business day after the dispute notice from Holder, the referee
     shall meet at the San Diego, California offices of Holder, or such other
     location as is mutually agreed upon by Licensor and Licensee, and shall
     hear testimony and other evidence that Licensor and Licensee may wish to
     present with respect to the dispute. The meetings shall be conducted from
     8:30 am. to 5:30 p.m. on no more than three (3) consecutive business days,
     national holidays excluded. Licensee shall present up to one day of
     evidence followed by up to one day of presentation from Licensor, followed
     by a final day reserved for rebuttal by each party in the morning and
     afternoon, respectively. Licensor, Licensee and Holder agree that the
     evidence and results of the hearings shall not be disclosed to third
     parties.
                                  PAGE 2 OF 10
<PAGE>
     Within two business days after the close of the presentations, the referee
     shall resolve the dispute by a written decision.

     This dispute resolution process shall be the exclusive means for resolving
     disputes regarding a release of the Deposit, and the decision of the
     referees shall be final, conclusive, and enforceable by a court of
     competent jurisdiction. All costs of the referee shall be split between
     Licensor and Licensee.

     Insofar as possible, the referee shall be, at the time of selection, a
     partner or manager of a national or regional accounting or software
     consulting firm (including the information processing, management support,
     and affiliates thereof) not employed by or affiliated with the Licensor or
     Licensee, and such referee shall be required to have relevant experience in
     the field of computer software technology and licensing. The sole issues
     for arbitration shall be whether there exists any material failure of
     Licensor to provide any support for the Software which it is obligated to
     provide under the Master Agreement and whether there has occurred a
     "Release Condition" under EXHIBIT I-2.

9.   JOINT RELEASE. Licensee and Licensor may, by joint written instruction to
     Holder, authorize the release of the Deposit or a copy of it to the party
     named in the instruction.

10.  RIGHTS IN DEPOSIT. Licensee's rights in the Deposit are stated in EXHIBIT
     I-3. This Agreement shall automatically terminate upon the termination of
     the Master Agreement, and notice shall be provided by Licensor and Licensee
     to Holder regarding such termination.

11.  TERM AND TERMINATION. The account will renew each year on the anniversary
     date upon receipt by Holder of the renewal fees.

     If Holder does not receive the renewal fee from Licensee by the anniversary
     date of this Agreement, Holder shall give notice to Licensor and Licensee.
     If the fee is not received from Licensee within thirty days of such notice,
     this Agreement shall automatically expire. Upon expiration of this
     Agreement, Holder will return the Deposit to Licensor. All obligations of
     Holder under this Agreement shall terminate thereafter, except as provided
     in this Agreement.

12.  FEES. All fees of Holder shall be due from Licensee in full upon receipt of
     Holder's invoice. Fees shall be those specified in Holder's schedule of
     fees in effect for the initial term of this Agreement plus taxes (unless
     Licensee provides evidence of tax-exempt status), which schedule of fees is
     attached as EXHIBIT I-4. Holder shall not increase fees during the term of
     this Agreement.

13.  ACCOUNT REPRESENTATIVE. Licensor, Licensee, and Holder shall each designate
     an authorized individual to receive notices and otherwise act on behalf of
     Licensor, Licensee and Holder in connection with this Agreement.
     Representatives may be changed by prior written notice to the other
     parties.

14.  NOTICES. All notices for a release or a dispute in connection with this
     Agreement shall be in writing addressed to the Account Representatives,
     shall be sent by overnight courier service or electronic facsimile
     transmission (with a confirmation copy to follow by first class mail,
     postage prepaid) and shall be effective at the end of the next business day
     following delivery.

15.  AUTHENTICITY. Holder may act in reliance upon any instruction, instrument,
     or signature believed to be genuine and may assume that it has been duly
     authorized.
                                  PAGE 3 OF 10
<PAGE>
16.  HOLD HARMLESS. Licensor and Licensee will hold Holder harmless against any
     action regarding the release or refusal to release a copy of the Deposit by
     Holder so long as Holder has acted in good faith and in accordance with
     this Agreement. Licensee and Licensor agree to defend and indemnify Holder
     and hold Holder harmless from and against any and all claims, actions and
     suits, whether in contract or in tort, and from and against any and all
     liabilities, losses, damages, costs, charges, penalties, counsel fees, and
     other expenses of any nature (including, without limitation, settlement
     costs) incurred by Holder as a result of performance of the Agreement,
     except in the event of a judgment which specifies that Holder acted in bad
     faith or with gross negligence or willful misconduct.

17.  GOVERNING LAW. This Agreement shall be governed by and construed in
     accordance with the laws of the State of New York without regard to its
     conflict of laws principles.

18.  PRIOR AGREEMENTS. The Master Agreement with each Licensee and this
     Agreement, including the Exhibits to both Agreements, constitute the entire
     agreement between the parties concerning the subject matter of this
     Agreement and the Deposit, and shall supersede all previous communications,
     representations, understandings, and agreements, oral or written, between
     and among the parties. Licensor and Licensee acknowledge that Holder has no
     knowledge of the terms and conditions contained in the Master Agreement and
     that Holder's only obligations shall be as set forth herein or in any other
     writing signed by Holder, Licensor and Licensee.

19.  SEVERABILITY. If any provision of this Agreement is held by any court to be
     invalid or unenforceable, then that provision will be severed from this
     Agreement and the remaining provisions shall continue in force.

20.  ASSIGNMENT. No party may assign any rights or delegate any obligations
     under this Agreement without the prior written consent of the others, and
     any attempt to do so shall be deemed void, except as provided in the Master
     Agreement. Any party may assign this Agreement to a successor to all or
     substantially all the capital stock or assets of a party, whether by sale,
     merger, tender offer or other form of acquisition.

21.  WAIVER. Waivers of any right under this Agreement shall only be effective
     if in writing signed by the party possessing the right.

                               RELEASE CONDITIONS
                               ------------------

The Deposit shall be released to Licensee upon the occurrence of any of the
following events:

1.   Failure of Licensor following Licensee's giving notice to Licensor, to
     fulfill its Software support obligations as required within the time
     periods permitted in the Master Agreement (the "Software Obligations").

2.   Failure of Licensor to continue to do business and such failure continues
     for a period of 90 days.

3.   Unless prohibited by law, the filing of a petition by or against Licensor
     for relief under the United States Bankruptcy Code; a general assignment
     for the benefit of creditors by Licensor; the appointment of a general
     receiver or trustee in bankruptcy for Licensor's business or property; or
     action by Licensor under any state insolvency or similar law for the
     purpose of its bankruptcy, or liquidation.

4.   Any rejection or termination of the Software Obligations by Licensor or its
     successors or representatives in breach of the provisions of the Software
     Obligations contained in the Master Agreement, including in all events any
     rejection or termination of the Software Obligations or any proposal to do
     so under Title 11 of the United State Code, as now constituted or hereafter
     amended (the "Bankruptcy Code"), or any other federal or state bankruptcy,
     insolvency, receivership, or similar law.

5.   Failure of a trustee, including Licensor as debtor in possession, in any
     bankruptcy case hereafter filed by or against Licensor either to assume the
     Software support obligations contained in the Master Agreement and this
     Master Source Code Escrow Agreement within forty-five (45) days after the
     filing of the initial bankruptcy petition or to perform such obligations
     and this Escrow Agreement within the meaning of Section 365(a)(4)(i) of the
     Bankruptcy Code.

     The rights in the Software, including associated intellectual property
rights, that Licensee may elect to retain following a rejection of the Master
Agreement or this Agreement under Section 365(n) of the Bankruptcy Code do not
include the right of Licensee to discontinue any royalty or other payment
obligation for use of Licensor's Software. Under no circumstances shall Licensee
be entitled to use of the Software under this Escrow Agreement without also
paying to Licensor (or its successors) any then-accrued or ongoing royalty,
distribution fee, other license fee payment obligation arising under the Master
Agreement, as well as payment for Presses under the Master Agreement. This
Agreement shall be automatically terminated at Licensor's option if Licensee
fails to make any such payment obligation following notice thereof from Licensor
or is otherwise in default of its obligations under the Master Agreement.

1.   A.   GRANT OF CURRENT LICENSE TO SOURCE CODE. Licensor hereby presently
grants to Licensee a limited license in the intellectual property content of the

Deposit is restricted solely to the furtherance of Licensee's rights or
fulfillment of Licensor's support obligations for the Licensor software as set
forth in the Master Agreement. The license includes the right to use, display
and perform any Deposit user documentation or Software (in machine-readable form

information of Licensor (including the Deposit material) refrain from any
unauthorized use or disclosure. All right, title, and interest to Software of
Licensor shall at all times remain vested in Licensor. The Software is the
exclusive property of Licensor and contains valuable proprietary information and
trade secrets of Licensor developed at a great cost and expense. Licensee agrees
not to translate, decompile, disassemble, reverse-engineer, create derivative
works, or take any other steps intended to produce a source language statement

the Software to others without the prior consent of Licensor, except as
contemplated by the Master Agreement or this Agreement. Any violation of the
foregoing restrictions shall terminate this Agreement and the Master Agreement.
Licensee will retain on each copy of the Software and user documentation that it
distributes any copyright, trademark, and other intellectual property rights of
Licensor.

return of the Deposit and payment of any fees to Holder. Licensee shall return
the Deposit materials in accordance with the standard requirements of Holder.

with all of the following provisions in its use of the Deposit materials

those of its employees and consultants who are directly involved in the use of

Licensee's permitted uses, and who have a need to know the contents of the
Deposit materials for the performance of their duties in connection with such
permitted uses.

     (iv) Licensee shall cause all of its employees and consultants who have
access to the Deposit materials to comply with all restrictions on the
confidentiality of the Deposit materials set forth in the Master Agreement or in
any Confidentiality Agreement between the parties.

use, Licensee shall locate the Deposit materials in a room or container which
shall be securely locked so as to preclude unauthorized persons from having
access to it. Only those employees referred to in paragraph (iii) above shall
have access to keys to the lock of such room or container; and Licensee shall
record the signature and date and hour of entry to and departure from such room
or container by all persons.

     (viii) Licensee shall not, and shall not permit any of its employees or
consultants to, reproduce or copy any of the Deposit material, or remove any
copyright or proprietary notice contained or included on or in the Deposit
material, or make any disclosure of the Deposit material, except to other
employees or consultants of Licensee as may be necessary or appropriate in
connection with their permitted use of Deposit material hereunder, or otherwise
attempt to transfer the Deposit material to anyone.

3.   RETENTION OF TITLE. Licensor retains sole and exclusive title to and
ownership of the Deposit materials (except to the extent of components thereof
which are licensed to Licensor by its licensors), and all patents, copyrights,
and other intellectual property rights in and to the Deposit materials.

4.   LICENSEE'S DEFAULT. If Licensee at any time defaults in its obligations
under the Master Agreement and such default is not remedied by Licensee within
any applicable grace period as provided in the Master Agreement and the Master
Agreement is terminated, Licensor may terminate the rights granted to Licensee
under this Escrow Agreement.

5.   USE OF DEPOSIT AT LICENSEE'S RISK. LICENSEE ACKNOWLEDGES THAT IT USES THE

                  timing of engineering changes other than safety changes.

5.       Response Time.
         -------------

         (a)      Presstek shall establish a work support process that includes
                  a "Customer Support Center" utilizing call logs and second and
                  third level support processes, together with a process for
                  implementing the escalation procedure outlined in Exhibit J-5.
                  A subject matter expert ("SME") will call the Customer within
                  [CONFIDENTIAL TREATMENT REQUESTED]/*/ minutes of being
                  assigned a Services call during the PPM.

         (b)      Presstek will provide Service to two types of Customers: (i)
                  those who enter a separate Service Contract with Presstek
                  ("Contract Customers"); and (ii) those that do not enter into
                  a separate Service Contract with Presstek ("Non-Contract
                  Customers").

                  (i)      Contract Customers. In the case of a Contract
                           Customer, upon either written or verbal notice by
                           Contract Customer to Presstek during the PPM that
                           remedial maintenance is required, Presstek's
                           qualified maintenance personnel shall arrive at the
                           Maintenance Site within [CONFIDENTIAL TREATMENT
                           REQUESTED]/*/ of notification and shall use
                           commercially reasonable efforts to accomplish the
                           necessary repairs as promptly as possible; provided,
                           however, that Presstek agrees during the term hereof
                           to use commercially reasonable efforts to decrease
                           this response time. If the required response time
                           should extend beyond the PPM, Presstek and Customer
                           (or Presstek and Xerox where Service is requested for
                           a Xerox-owned machine) shall mutually agree whether
                           such Services shall be performed at such time or
                           during the next PPM. If Presstek's maintenance
                           personnel fail to arrive or use commercially best
                           efforts to be fully prepared to perform Services
                           within the required response time period, the
                           Customer, shall receive a credit from Presstek in an
                           amount set out under the terms of the Service
                           Agreement between Presstek and the Contract Customer.

                  (ii)     Non-Contract Customers. In the case of a Non-Contract
                           Customer, upon either written or verbal notice by
                           Non-Contract Customer to Presstek during the PPM that

                           required response time should extend beyond the PPM,
                           Presstek and the Customer (or Presstek and Xerox
                           where Service is requested for a Xerox-owned machine)
                           shall decide whether such Services shall be performed
                           at such time or during the next PPM. If Presstek's
                           maintenance personnel fail to arrive or use
                           commercially best efforts to be fully prepared to
                           perform Services within the required response time
                           period, the Non-Contract Customer shall be entitled
                           to a [CONFIDENTIAL TREATMENT REQUESTED]/*/ discount
                           for maintenance charges payable to Presstek
                           hereunder.

         (c)      In addition to and without limiting the foregoing, any and all
                  Customers identified software problems will be managed through
                  a Presstek process generally equivalent to the Xerox Software
                  Problem Action Request Process (SPAR Process). SPAR(s) are
                  rated by severity of the Product Failure (as defined in the
                  Distribution Agreement) and defined as follows:

                  SEVERITY LEVEL 1 shall be defined as a "catastrophic problem"
                  wherein the Customer's system is down, and/or the user has no
                  production capability, or a field service technician cannot
                  proceed with an installation.
                  SEVERITY LEVEL 2 shall be defined as a "severe problem"
                  wherein the Customer's system is up, but production capability
                  is seriously degraded.
                  SEVERITY LEVEL 3 shall be defined as a "moderate problem"
                  wherein the Customer's system is up, but production capability
                  is reduced.
                  SEVERITY LEVEL 4 shall be defined as a "minor problem" wherein
                  the Customer's system is up, with no significant impact to
                  production.

6.       Problem Severity Response Time/Resolution Time.  Presstek will make
         every commercially reasonable attempt to achieve the following Response
         Times and Target Resolution Times for each SPAR:

         SEVERITY              RESPONSE TIME       TARGET RESOLUTION TIME

         Level (1)             [CONFIDENTIAL TREATMENT REQUESTED]/*/
         Level (2)             [CONFIDENTIAL TREATMENT REQUESTED]/*/
         Level (3)             [CONFIDENTIAL TREATMENT REQUESTED]/*/
         Level (4)             [CONFIDENTIAL           the next version of
                               TREATMENT REQUESTED]/*/ the Product(s)

         Presstek will use commercially reasonable efforts to remedy or
         ameliorate the problem within a commercially reasonable period,
         depending on the severity of the problem. Failure of Presstek to meet
         the above Response Times and Target Resolution Times shall not be
         considered a breach of this Service Agreement, provided that Presstek
         makes every commercially reasonable attempt to do so as provided
         herein.

material has been filed with the Commission pursuant to Rule 24b-2 promulgated
under the Securities and Exchange Act of 1934, as amended.
<PAGE>
         Notwithstanding the foregoing, Presstek's failure to achieve the above
         Response and Target Resolution Times for at least [CONFIDENTIAL
         TREATMENT REQUESTED]/*/ of SPARs in any rolling [CONFIDENTIAL TREATMENT
         REQUESTED]/*/ month period shall constitute a material breach of this
         Service Agreement.

         "Response Time" is defined as the time necessary to (a) acknowledge the
         receipt of a problem, or (b) request any additional information as is
         necessary for the Presstek Technical Support group to escalate the
         problem to the Presstek QA or engineering groups for resolution. In the
         event of (b) above, the Presstek Technical Support group will be
         responsible for monitoring the timeliness of the QA/Engineering
         response, as well as keeping the OEM Technical Support group updated as
         to the status of the problem. In the case of a problem submitted by
         telephone, it is assumed that the response is immediate in that the
         call is answered as soon as a Presstek Technical Support representative
         is available to answer.

         "Resolution Time" is defined as the time necessary to provide a
         software fix or work around, explanation of functionality or other such
         item as to (a) resolve the customer's problem where it is proven to be
         the fault of Product software or firmware, and/or (b) provide
         reasonable explanation or evidence that the problem is not the result
         of Presstek firmware or software. Presstek Technical Support will use
         commercially reasonable efforts when resolving Customer issues for
         Xerox.

         Presstek shall have the additional SPAR responsibilities set forth on
         Exhibit J-6.

7.       Customer Satisfaction Surveys. The parties shall jointly agree upon a
         format for and administer a Customer Service Satisfaction Survey.
         Presstek shall achieve an average monthly score on such Customer
         Service Satisfaction Survey of not less than [CONFIDENTIAL TREATMENT
         REQUESTED]/*/. Should Presstek achieve an average monthly score below
         [CONFIDENTIAL TREATMENT REQUESTED]/*/ but above [CONFIDENTIAL TREATMENT
         REQUESTED]/*/ for [CONFIDENTIAL TREATMENT REQUESTED]/*/, the parties
         shall meet to agree on a course of remedial action. Should Presstek
         achieve an average monthly score below [CONFIDENTIAL TREATMENT
         REQUESTED]/*/ but above [CONFIDENTIAL TREATMENT REQUESTED]/*/ for any
         [CONFIDENTIAL TREATMENT REQUESTED]/*/ months, Xerox may consider such
         action a material breach of this Service Agreement. Should Presstek
         achieve an average monthly score of [CONFIDENTIAL TREATMENT
         REQUESTED]/*/ or below for any [CONFIDENTIAL TREATMENT REQUESTED]/*/,
         Xerox may consider such action a material breach of this Service
         Agreement. The parties agree to renegotiate the minimum average score
         for purposes of this Section on an annual basis to reflect
         year-over-year improvements and productivity.

8.       [CONFIDENTIAL TREATMENT REQUESTED]/*/ Configuration Units of PAX
         Products. Presstek shall not charge Customers for Services rendered
         with respect to the [CONFIDENTIAL TREATMENT REQUESTED]/*/ [CONFIDENTIAL

V.       SPARES

1.       Spares Inventory. At the commencement of this Service Agreement,
         Presstek shall (a) provide Xerox with a list of repairable and
         non-repairable parts and (b) compile a Spares inventory, such inventory
         to be Presstek's estimate of the parts reasonably necessary to allow
         for the provision of Services to Customers. These Spares shall at all
         times remain the property of Presstek until and unless they are
         provided to Customers as part of the Services. Presstek shall maintain
         spares at an adequate level in [CONFIDENTIAL TREATMENT REQUESTED]/*/
         and [CONFIDENTIAL TREATMENT REQUESTED]/*/ (and such other geographic
         locations in which the parties agree to market and distribute the
         Products, the timing thereof to be negotiated and agreed, provided that
         Presstek must meet Xerox' launch requirements concerning Spares) to
         support the then current installed base of Products. Presstek will also
         make available to Customers a list of all spares that Presstek
         reasonably believes should be kept on site and of which the Customer
         may want to keep in the Customer's inventory.

2.       Emergency Spares Inventory. Presstek shall at all times maintain an
         adequate inventory of each Spare, at no cost to Xerox, and use this
         supply of Spares solely for shipment to Xerox or its Customers as
         emergency Spares, when requested. Deliveries of emergency Spares shall
         be made as promptly as practicable but not more than [CONFIDENTIAL
         TREATMENT REQUESTED]/*/ hours of Xerox' or Customer's written or verbal
         request to Presstek.

3.       Spares Delivery and Invoicing.  Presstek will supply Spares directly to
         and invoice Xerox/the Customer in accordance with mutually agreed upon
         terms.

4.       Continuity of Supply. Presstek shall make available to Xerox and its
         Customers Spares (as that term is defined in the Distribution
         Agreement) for a period of [CONFIDENTIAL TREATMENT REQUESTED]/*/ years
         from the last delivery of Products under the Distribution Agreement and
         notwithstanding any termination or expiration hereof.

5.       Equivalent Spares. Xerox agrees to accept equivalent and/or
         interchangeable (form, fit and function compatible as defined herein)
         Spares during the [CONFIDENTIAL TREATMENT REQUESTED]/*/ year period set
         forth above, if Presstek's source of supply should change and such
         change is beyond Presstek's reasonable control. The determination as to
         whether Spares are equivalent and/or interchangeable shall be made by
         mutual agreement of the parties.

6.       Payment Terms. Payment for Spares shall be due within [CONFIDENTIAL
         TREATMENT REQUESTED]/*/ days of Xerox' or the Customer's receipt of
         correct invoice, subject to Presstek's credit approval of the Customer.

7.       Shipping Terms.  Shipping terms for Spares shall be as agreed by the
         parties.

8.       Priority. Presstek shall use commercially reasonable efforts to supply
         Spares and Consumables at the lead time agreed upon by the parties on a
         priority basis to Customers and to Xerox to replenish any Xerox low
         stock condition, and shall immediately upon receipt of relevant
         purchase orders notify Xerox of the anticipated shipment date of all
         Spares orders.

                  unavailable to do so for any reason, Presstek shall replace
                  that person with one of comparable ability.

                  subcontractors, upon or in relation to the fulfillment of
                  responsibilities and obligations under this Service Agreement,

         [CONFIDENTIAL TREATMENT                     [CONFIDENTIAL TREATMENT

2.       Independent Contractor. Xerox and Presstek agree that the relationship
         between them is one of principal and independent contractor and that
         neither Presstek nor its employees shall be considered employees of
         Xerox. Accordingly, neither Presstek nor its employees shall be
         entitled to any employment benefits made available by Xerox to its own
         employees. Furthermore, both parties recognize that Presstek controls
         and is responsible for: (a) the manner and means by which Presstek
         conducts the Services and ensuring that its work product fully meets
         the standards for acceptable performance established under this Service
         Agreement; (b) the scope of its business enterprises (including
         Presstek's solicitation of other customers and lines of business) and
         the hours during which they are conducted; (c) the payment of all taxes
         associated with the payments (including but not limited to all social
         security and income taxes); (d) all matters and obligations concerning
         its employees; (e) all travel costs and arrangements required to
         perform the Services (except for amounts properly charged by Presstek
         in connection with Services performed as set forth herein); and (f) the
         maintenance of its places of business and all associated costs.
         Presstek shall maintain such workers' compensation policies as are
         required by statute, as well as comprehensive general liability and
         comprehensive automobile liability insurance with limits for bodily
         injury and property damage on each such policy of at least one million
         dollars. Upon request by Xerox, Presstek shall provide Xerox with
         copies of the policies evidencing such insurance.

3.       Confidential Information. In addition to the parties' obligations under
         the Confidential Disclosure Agreement dated July 22, 1998, Presstek may
         from time to time have access to or receive directly from Xerox
         information and materials that are designated as confidential or

                                      -20-
<PAGE>
         proprietary or which are by their nature confidential, proprietary, or
         sensitive, This shall specifically include, but not be limited to, all
         technical manuals, reports (such as [CONFIDENTIAL TREATMENT
         REQUESTED]/*/) and documentation relating to the provision of the
         Services, In addition, such information and materials may concern
         present or future Xerox products, business strategies, or customers.
         Presstek shall hold such information and materials in confidence, shall
         not use them except to perform its duties under this Service Agreement,
         and shall not disclose them to third parties unless authorized in
         writing by Xerox, Presstek's obligations under this paragraph shall
         survive the termination of this Service Agreement.

4.       Remedies. Presstek acknowledges that it will be the preferred supplier
         of the Services for the Products referred to in this Service Agreement
         and that these Products, and the Services, are critical to Xerox'
         business. Accordingly, and in addition to any other remedies to which
         Xerox may be entitled in law and equity:

         (a)      In the event that any default by Presstek of its obligations
                  hereunder results in a Customer terminating or canceling a
                  sale of Product(s) before all payments due and owing for such
                  Product(s) have been paid in full; or, with respect to a
                  Customer leasing Products from Xerox, defaulting in its lease
                  payments and/or terminating or canceling its lease before all
                  lease payments due and owing thereunder have been paid in
                  full; (i) PRESSTEK shall [CONFIDENTIAL TREATMENT
                  REQUESTED]/*/. In addition, where any default by Presstek of
                  its obligations hereunder results in a Customer terminating or
                  canceling its lease before all lease payments due and owing
                  thereunder have been paid in full, for each month that the
                  Product has not been re-leased, sold or otherwise transferred
                  to a new Customer and for which lease payments have not been
                  received by Xerox, Presstek shall pay to Xerox an amount
                  [CONFIDENTIAL TREATMENT REQUESTED]/*/. PRESSTEK's obligation
                  to [CONFIDENTIAL TREATMENT REQUESTED]/*/ are contingent upon
                  Xerox using commercially reasonable efforts in locating a new
                  Customer for the Product.

         (b)      The parties agree that in the event of any dispute (including
                  without limitation any under the Distribution Agreement),
                  Presstek shall continue to supply Services and Xerox shall
                  continue to compensate Presstek pursuant to the terms hereof
                  pending resolution of such dispute by negotiation or legal
                  process.

5.       Non-Assignability. Except as set forth in [CONFIDENTIAL TREATMENT
         REQUESTED]/*/ Section II.2 of this Service Agreement, neither party may
         assign its rights and obligations under this Service Agreement without
         the consent of the other party; provided, however, that each party may
         assign this Agreement in connection with (a) the sale of all or
         substantially all of the capital stock or assets of such party, or (b)
         the acquisition by a third party of a party to this Agreement by
         merger, consolidation, reorganization or other business combination
         whereby more than fifty (50) percent of
