REQUESTED]/*/ stage. After the end of production of the [CONFIDENTIAL TREATMENT
REQUESTED]/*/, both parties to this Agreement shall agree on the production
documentation. This shall be done prior to the beginning of delivery of the

conform to CE or EU requirements regulating health and/or safety ("Safety
Problems"). Where a party receiving a good discovers a Safety Problem (the
"Discovering Party"), that party will, without delay, immediately notify the
party that sent the item (the "Producing Party") of the Safety Problem.

               i. Upon receipt of notification of the Safety Problem the
           Producing Party shall, within five days, dispatch an individual or
           individuals sufficiently trained to remedy the Safety Problem (the
           "Repair Team") to arrive at the site and design a remedy to the
           Safety Problem. Upon designing a remedy, the Repair Team shall have
           agreed time to implement the remedy, unless such agreed time limit is
           extended by consent of the Discovering Party, such extension of time
           shall not be unreasonably withheld. Should the Repair Team fail to
           implement a remedy to the Safety Problem within ten days (or within
           an additional time if so extended by the Discovering Party), the
           Discovering Party shall then have the right to reasonably design and
           implement a remedy to the Safety Problem. In either case, the cost of
           remedying the Safety Problem shall be borne by the Producing Party.
           The presses are designed according to the safety regulations valid in
           European Union (CE). If such valid legal regulation or other
           requirement concerning the respective order requires a design change
           in the presses ordered, the reasonable costs for the design changes
           of the press for the respective region shall be born by PRESSTEK.

               ii. Should a Producing Party be notified of a Safety Problem, the
           Producing Party shall modify their design in order to remedy the
           Safety Problem for all products that have not been shipped. Such
           modification shall occur prior to the next shipment of the product.
           In the event that, as a result of implementing the remedy, it becomes
           necessary for ASA to change the design or technology or way of
           manufacturing which will have an effect on the selling price both
           parties shall mutually agree on the change. If this remedy causes an
           increase in the cost of the Presses, the other side is obliged to
           accept any reasonable increase in sale price. In the case that the
           remedy has an effect on the shipping date of the ordered presses both
           parties agree in writing upon the change of the shipping dates of the
           presses.

           b. Upon completion of the development stage, at PRESSTEK's sole
election and at PRESSTEK's sole and commercially reasonable expense, ASA shall
either (i) upgrade the pre-production presses to production performance levels
and full compliance with the Specifications at the conclusion of the
pre-production process, the foregoing at such locations as PRESSTEK may direct
at its sole discretion; or (ii) provide information materials and training to
individuals designated by PRESSTEK sufficient to allow such individuals to
perform upgrades of the pre-production Presses. The costs related to upgrades

similar marks which may constitute an infringement or passing off of the other's

its sole discretion to institute any proceedings against such third party
infringers and the other party shall refrain from doing so. The party whose
trademark is not being infringed agrees to cooperate fully with the other party
in any action taken by the other party against such third parties, provided that
all expenses of such action shall be borne by the other party and all damages
which may be awarded or agreed upon in settlement of such action shall accrue to
the other party.

     6.4 INDEMNIFICATION.

           a. INDEMNIFICATION BY ASA. (i) If a third party claims that any Press
     violates any applicable safety or regulatory standard or has caused
     personal injury, including death, or damage to property, ASA will defend
     PRESSTEK, and PRESSTEK's respective authorized resellers, customers and
     officers, directors employees and representatives ("PRESSTEK Indemnitees")
     against that claim at ASA's expense. ASA's obligation to defend any such
     claim arises upon PRESSTEK promptly notifying ASA in writing of the claim,
     and allowing ASA to control, and to cooperate with ASA in, the defense of
     the claim or any settlement.

           (ii) If a third party claims that any ASA Proprietary Right or Press
     infringes a patent, copyright, trademark or trade secret, ASA, at ASA's
     expense will defend PRESSTEK's Indemnitees against that claim and either
     (A) procure for PRESSTEK Indemnitees the right to continue using the ASA
     Proprietary Right or Press that is the subject of the claim; or (B) modify
     or replace the ASA Proprietary Right or Press with non-infringing
     components having the same or substantially equivalent features and
     functionality. If neither option A nor B is available to ASA, ASA shall
     refund a portion of the license fee based on the depreciated value of the
     Software. ASA's obligations to defend PRESSTEK Indemnitees and either
     procure license(s) or modify or replace the ASA Proprietary Right or Press
     (as those obligations are described in this paragraph) arise upon PRESSTEK
     promptly notifying ASA in writing of the claim, and allowing ASA to
     control, and to cooperate with ASA in, the defense of the claim or any
     settlement.

           b. INDEMNIFICATION BY PRESSTEK. (i) If a third party claims that any
     Presstek Kit violates any applicable safety or regulatory standard or has
     caused personal injury, including death, or damage to property, PRESSTEK
     will defend ASA, and ASA's respective

                                       17

           authorized resellers, customers and officers, directors employees and
           representatives ("ASA Indemnitees") against that claim at PRESSTEK's
           expense. PRESSTEK's obligation to defend any such claim arises upon
           ASA promptly notifying PRESSTEK in writing of the claim, and allowing
           PRESSTEK to control, and to cooperate with PRESSTEK in, the defense
           of the claim or any settlement.

                     (ii) If a third party claims that any PRESSTEK Proprietary
           Right or Presstek Kit infringes a patent, copyright, trademark or
           trade secret, PRESSTEK, at PRESSTEK's expense will defend ASA
           Indemnitees against that claim and either (A) procure for ASA
           Indemnitees the right to continue using the PRESSTEK Proprietary
           Right or Presstek Kit that is the subject of the claim; or (B) modify
           or replace the PRESSTEK Proprietary Right or Presstek Kit with
           non-infringing components having the same or substantially equivalent
           features and functionality. If neither option A nor B is available to
           PRESSTEK, PRESSTEK shall refund a portion of the license fee based on
           the depreciated value of the Software. PRESSTEK's obligations to
           defend ASA Indemnitees and either procure license(s) or modify or
           replace the PRESSTEK Proprietary Right or Presstek Kit (as those
           obligations are described in this paragraph) arise upon ASA promptly
           notifying PRESSTEK in writing of the claim, and allowing PRESSTEK to
           control, and to cooperate with PRESSTEK in, the defense of the claim
           or any settlement.

     6.5 TERMINATION OF USE.

           a. PRESSTEK acknowledges ASA's Proprietary Rights and rights in and
to the ASA trademarks and any tradenames regularly applied by ASA to the
Purchased Goods, and PRESSTEK hereby waives in favor of ASA all rights to any
trademarks, tradenames and logotypes now or hereafter originated by ASA.

negotiate a mutually acceptable alternative provision not conflicting with such

                            CONFIDENTIALITY AGREEMENT

           THIS CONFIDENTIALITY AGREEMENT (the "Confidentiality Agreement") is
made and entered into as of the 14th day of March, 2000, by and between
Presstek, Inc. having an office and place of business at 9 Commercial Street,
Hudson, New Hampshire 03051, USA (hereinafter referred to as "PRESSTEK"), and
ADAMOVSKE STROJIRNY a.s., Mirova 2, organized and existing under the laws of the
Czech Republic, having an office and place of business at 67904 Adamov, Czech
Republic (hereinafter "ADAST").

           WHEREAS, PRESSTEK and ADAST, simultaneous with the execution of this
Confidentiality Agreement, are entering into a development and supply agreement
(the "Agreement"); WHEREAS, PRESSTEK, Omnitrade Industrial Company, and ADAST
are parties to a confidentiality agreement to hold certain information
confidential dated March 13, 1997 which is replaced by this Confidentiality
Agreement;

           WHEREAS, PRESSTEK and ADAST may need to disclose to each other
certain confidential and proprietary information including trade secrets and
information contained in pending patent applications relating to their
respective technologies;

           WHEREAS, the parties now desire to provide in more detail for the
preservation of confidential information disclosed by one party to the other in
the course of their dealings;

                                       44

<PAGE>

           NOW, THEREFORE, in consideration of the mutual promises herein
contained, the parties have agreed as follows:

           1. Information communicated by one party (the "Disclosing Party") to
the other (the "Receiving Party") which the Disclosing Party considers
confidential shall, when communicated in documentary form or on computer tape or
disc, be marked as "Confidential" In the event information is communicated
orally or by transfer of non-documentary materials, the confidential nature of
such information shall be confirmed to the Receiving Party in writing within
twenty days after such disclosure. "Confidential Information" shall mean any and
all information in any form with respect to the Disclosing Party's technical or
business matters which are designated by the Disclosing Party as "confidential"
in the manner set forth above. Notwithstanding the provisions of this paragraph,
it is agreed that all disclosure of information with respect to said subjects
shall be considered "Confidential Information," regardless of the form in which
it is communicated and whether marked "confidential" or not, unless otherwise
indicated in writing by the Disclosing Party.

           2. The Receiving Party shall maintain all Confidential Information of
the Disclosing Party in strict confidence, shall not publish, disseminate,
disclose or otherwise make such Confidential Information available to any third
party, and shall not use such Confidential Information for any purpose other
than for the benefit of the Disclosing Party in a manner approved by the
Disclosing Party. The Receiving Party agrees to limit the dissemination of, and
access to, the Confidential Information to employees of the Receiving Party
(together with its legal advisors) who have a "need to know" such information,
provided that such employees shall

                                       45

<PAGE>

have entered into appropriate confidentiality relationships with the Receiving
Party so as to ensure that the Receiving Party has the legal right to implement
the terms and conditions of this Confidentiality Agreement.

           3. Notwithstanding paragraph 2 of this Confidentiality Agreement, the
obligations of confidentiality and non-use on the part of the Receiving Party
shall not apply to information which:

               (a) the Receiving Party can establish was publicly known or was
known to the Receiving Party at the time of disclosure;

               (b) becomes publicly known subsequent to the time of disclosure,
provided that such public knowledge is not the result of disclosure of
Confidential Information by the Receiving Party;

               (c) is approved for release by prior written authorization of the
Disclosing Party; or

               (d) is required to be disclosed by applicable law, regulation or
legal process (whether by subpoena, civil investigative demand, or other similar
process), provided that if the Receiving Party is so required to disclose any of
the Confidential Information the Receiving Party will provide the Disclosing
Party with prompt notice of any such request of which the Receiving Party has
knowledge so that the Disclosing Party may seek a protective order or other
appropriate remedy or waive the Receiving Party's compliance with the provisions
of this Confidentiality Agreement, as appropriate. Regardless of whether the
Disclosing Party waives compliance with the terms hereof, or whether a
protective order or other appropriate remedy is

                                       46

<PAGE>

obtained, the Receiving Party will furnish only that portion of the Confidential
Information which is required to be disclosed by such applicable law, regulation
or legal process.

           4. At the request of the Disclosing Party, and subject to the
obligations of the Disclosing Party, if any, under the Agreement, all
Confidential Information in any tangible form received by the Receiving Party
and all documents, notes, sketches, prototypes, discs, tapes, records or other
written materials prepared by the Receiving Party containing or reflecting such
Confidential Information or abstracts or summaries thereof shall be promptly
returned to the Disclosing Party, together with all copies thereof.

           5. Nothing contained in this Confidentiality Agreement shall be
construed as requiring either party to disclose any specific information to the
other, nor as a grant by implication, estoppel or otherwise of any license to
make, have made, use or sell any product or as a license under any patent,
patent application, utility model, copyright, trade secret or any other
proprietary right.

           6. This Confidentiality Agreement shall be in force from the time it
is signed by both parties for a period of not less than [CONFIDENTIAL TREATMENT
REQUESTED]/*/ after such signature; provided that this Confidentiality Agreement
shall remain in force for so long as the Agreement remains in force and for a
period of [CONFIDENTIAL TREATMENT REQUESTED]/*/ thereafter; and provided further
that, as to documentation containing Confidential Information which is
designated by a party as "Super Confidential," this Confidentiality Agreement
shall

remain in force beyond the period specified in this paragraph for so long
as such information remains confidential.

           7. The parties acknowledge and agree that a breach of this
Confidentiality Agreement by either of them would cause irreparable damage to
the non-breaching party, that such damage would be difficult to measure, and
that such damage may not be adequately compensated by monetary damages.
Consequently, the parties agree that each shall be entitled to equitable relief,
including injunction and specific performance, in the event of any breach of the
provisions of this Confidentiality Agreement, in addition to all remedies
available to the parties at law or in equity.

           8. This Confidentiality Agreement contains the entire agreement
between the parties concerning disclosure and use of Confidential Information,
cannot be altered except by an agreement between the parties in writing, shall
be interpreted in accordance with the laws of England, and all parties to this
Confidentiality Agreement hereby subject themselves to the jurisdiction of the
Courts of England to enforce the provisions of this Confidentiality Agreement.

           IN WITNESS WHEREOF, the parties have caused this Confidentiality
Agreement to be executed by their duly authorized representatives.

organized and existing under the laws of the Czech Republic, having an office

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

1.     DEPOSIT. Licensor shall deposit with Holder those source code materials

       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 A. Risk of loss or
       damage to the Deposit materials during shipment shall lie with the
       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

       personnel as reasonably necessary to verify the Deposit.

4.     STORAGE OF DEPOSIT. Holder shall safekeep the Deposit in a security vault

       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 B, 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

                                       51

<PAGE>

       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.

       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 Production Agreement and
       whether there has occurred a "Release Condition" under EXHIBIT B.

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.

                                       52

<PAGE>

10.    RIGHTS IN DEPOSIT. Licensee's rights in the Deposit are stated in EXHIBIT
       C. This Agreement shall automatically terminate upon the termination of
       the Production 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 D. 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.

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

                                       53

<PAGE>

       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 Production 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
       Production 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

       to all or substantially all the capital stock or assets of a party,
       whether by sale, merger, tender offer or other form of acquisition.

                               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 Production 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 Production 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 Production 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
Production 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

                                       58

license fee payment obligation arising under the Production Agreement, as well
as payment for Presses under the Production 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 Production Agreement.

                                ESCROW MATERIALS

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, exercisable upon release of the Deposit by Holder to Licensee under the
Release Conditions. Licensee's license is limited, non-exclusive, and
fully-paid-up. Licensee's license to the Deposit materials hereunder is limited
in duration to the term of the Production Agreement. Licensee's license to 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 Production Agreement. The license includes the right to use,
display and perform any Deposit user documentation or Software (in
machine-readable form only). No right is provided to Licensee to copy (except
for archive purposes), manufacture, reproduce or distribute or transfer to
others copies of the Software or documentation, except as contemplated by the
Production Agreement or this Agreement. Use of the Source Code by Licensee shall
be limited to the uses of the System permitted under the Production Agreement
and shall be limited to use within the Territory as provided in the Production
Agreement.

       B. PROTECTION OF INTELLECTUAL PROPERTY RIGHTS IN SOFTWARE. Licensee shall
treat the Deposit and Related Materials as confidential information. Licensee
shall maintain all confidential information in strict confidence. Licensee shall
take all commercially reasonable steps to ensure that no unauthorized person or
entity has access to such confidential information of Licensor (including the
Deposit material) and that all authorized persons having access to confidential
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
of the Software and not to copy, reproduce, distribute, transfer, or disclose
the Software to others without the prior consent of Licensor, except as
contemplated by the Production Agreement or this Agreement. Any violation of the
foregoing restrictions shall terminate this Agreement and the Production
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.

       C. RETURN OF DEPOSIT. Licensee shall immediately return the Deposit
materials if Licensor has cured the release conditions giving rise to the
release of the Deposit and resumes performance of its obligations under the
Production Agreement. The Escrow Agreement shall be

                                       60

standard requirements of Holder.

any such contents as required for the exercise of Licensee's rights pursuant to
this Escrow Agreement and the Production Agreement.

                (ii) The Deposit materials shall remain on Licensee's premises
at all times and shall be returned to the secure location when not in direct or
immediate use.

                (iii)Licensee shall limit use of, and access to, the Deposit
materials to those of its employees and consultants who are directly involved in
the use of the Deposit materials to support the Licensor Software and/or to
carry out 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 Production Agreement
or in any Confidentiality Agreement between the parties.

                (v)Licensee shall assist Licensor in identifying and preventing
any use or disclosure of the Deposit material by the present or former employees
or consultants of Licensee in any manner which is not expressly permitted by the
Escrow Agreement or Production Agreement.

                (vi)Licensee shall be liable for all damages or costs suffered
by Licensor in connection with any unauthorized transfer, disclosure, copying,
duplication, reproduction or use or misappropriation of the Deposit material by
Licensee or its employees or consultants.

                (vii)At all times during which any portion of the Deposit
materials is in 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 Production Agreement and such default is not remedied by Licensee within any
applicable grace period as provided in the Production Agreement and the
Production 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
DEPOSIT MATERIALS AT ITS OWN RISK.

                     cause each such Registration Statement relating to the
                     Registrable Securities to become effective as soon as
                     practicable after such filing, and use best efforts to take

                     used in connection with each Registration Statement as is

                     Statement until the termination of the Registration Period

                     Registration Statement to become effective as soon as
                     practicable following the filing thereof."

           6.        The first sentence of Section 3.4 of the Registration
Rights Agreement is hereby deleted in its entirety and replaced with the
following:

                     "The Company shall (a) use best efforts to take all actions

                     Securities covered by each Registration Statement under
                     securities laws of such jurisdictions in the United States
                     as each Purchaser who holds (or has the right to hold)
                     Registrable Securities being offered reasonably requests,
                     (b) prepare and file in those jurisdictions such amendments
                     (including post-effective amendments) and supplements to
                     such registrations and qualifications are consistent with
                     the Company's obligation to use best efforts to
<PAGE>

                     take all actions reasonably required to maintain the
                     effectiveness and availability for use thereof during the
                     applicable Registration Period, (c) use best efforts to
                     take such other actions as may be reasonably required to
                     maintain such registrations and qualifications in effect at
                     all times during the applicable Registration Period, and
                     (d) use best efforts to take all other actions reasonably
                     required to qualify the Registrable Securities for sale in
                     such jurisdictions; provided, however, that the Company
                     shall not be required in connection therewith or as a
                     condition thereto to (i) qualify to do business in any
                     jurisdiction where it would not otherwise be required to
                     qualify but for this Section 3.4, (ii) subject itself to

                     general consent to service of process in any such
                     jurisdiction, (iv) provide any undertakings that cause the
                     Company material expense or burden, or (v) make any change
                     in its charter or by-laws, which in each case the board of
