                breach within thirty (30) days of the receipt of written notice
                from the other party requiring it to do so; or

        d)      suffers a substantial change in the identity of its major

             ------------------------------------------------------

This Amendment is made and entered into as of February 1, 1996, by and between

Inc., (hereinafter referred to as "CALCOMP").

                                R E C I T A L S
                                ---------------

WHEREAS KTA and CALCOMP have entered into an Agreement effective January 9, 1996
for the distribution of the Model 2700 Digital Print Engine.

WHEREAS the parties hereto wish to amend the Agreement in order to provide for
certain matters not previously addressed and to modify certain other terms;

NOW, THEREFORE, the parties hereto agree to amend the Agreement as follows:

1)      Article 4 PRICING AND PAYMENT - Paragraph 4.1 revise wording as follows:

        "The prices for 120/220 volt unit and 100 volt unit of the MACHINE
        respectively shall be as set out in Annex II hereto, the 120/220 volt
        units of which shall be subject to adjustment with respect to
        fluctuations in the exchange rate as stated in Annex IV hereto.  The
        prices for SUPPLY PRODUCTS are set out in Annex III hereto."

2)      Article 5 TECHNICAL TRAINING AND MANUALS - Paragraph 5.2 - revise
        wording as follows:

        "CALCOMP may prepare, at its own cost, its own manuals and catalogues
        regarding the OEM PRODUCTS.  For that purpose KTA shall, upon request,
        furnish to CALCOMP, free of charge, all information regarding the
        CONTRACT PRODUCTS which may reasonably enable CALCOMP to prepare such
        documentation, including one (1) set in English of the parts manual,
        service manual, operation manual and interface-specifications for the
        CONTRACT PRODUCTS.  KTA grants CALCOMP the right and license, subject to
        the provisions of Article 10 Secrecy, to use, reproduce, modify,
        translate and distribute the documentation and training materials with
        legally effective copyright notice; provided however, that KTA shall
        not be liable for any damages incurred by CALCOMP or a third party due
        to, and CALCOMP shall indemnify and hold KTA harmless from liability for
        any damages incurred by CALCOMP or a third party due to any errors or
        omissions in the documentation used by CALCOMP using any information so
        provided by KTA."

3)      Article 7 WARRANTY - Paragraph 7.1 - revise wording as follows:

        "KTA warrants that all CONTRACT PRODUCTS shall be free from defects in
        design, material and workmanship and shall be and operate according to
        the specifications appearing in Annex I; provided, however, that such
        warranty shall not apply to any defects which occur or arise as a result
        of changes in aspects, features or details of the CONTRACT PRODUCTS
        which are incorporated therein, adopted or implemented as a result of
        requests originated by CALCOMP, provided that a CALCOMP officer has
        previously agreed in writing that said warranty will not apply as a
        result of the incorporation, adoption, or implementation of said
        aspects, features or 

Date Revised: May 13, 1996                                                   1

        details. The said warranty shall apply during a period of six (6) months
        after installation of the OEM PRODUCTS at CALCOMP's customers' premises
        or for twelve (12) months after the date of shipment, whichever period
        is shorter, and is subject to the condition that CALCOMP has notified
        KTA in writing or by facsimile of any warranty claim within the warranty
        period. If such notice is sent by facsimile, CALCOMP shall promptly send
        to KTA a confirmation copy of the same by mail.

        The aforementioned warranty period shall be extended to three (3) years
        from the relevant shipping date for any latent defect which causes a
        breach of warranty in a series (for example, a range of serial numbers)
        of the CONTRACT PRODUCT resulting from a common defect in the CONTRACT
        PRODUCTS that was not discernible from an inspection and test of
        CONTRACT PRODUCTS.  In the event such latent defect is agreed by KTA
        and CALCOMP in writing, then CALCOMP may elect to enter into a field
        replacement program of the affected part or assembly, prior to its
        failure, so as to prevent or minimize any liability or end user
        dissatisfaction with the CONTRACT PRODUCT.  In such case KTA shall
        provide replacement parts at no cost."

4)      Article 7 WARRANTY - Paragraph 7.5 - replace this paragraph with the
        following:

        "THIS WARRANTY IS IN LIEU OF ALL OTHERS, EXPRESS OR IMPLIED, INCLUDING
        BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS
        FOR A PARTICULAR OR INTENDED PURPOSE, AND ACTION UNDER THIS WARRANTY
        SHALL BE THE EXCLUSIVE REMEDY.  NEITHER PARTY SHALL BE LIABLE TO THE
        OTHER FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES RESULTING FROM A
        BREACH OF ITS OBLIGATIONS HEREUNDER EXCEPT IN THE CASE OF A MATERIAL OR
        WILLFUL BREACH."

5)      Article 10 SECRECY - sub-paragraph (a) - revise wording as follows:

        "All information in written or other physical form, delivered to it by
        the other party and which is designated to be proprietary and
        confidential will be safeguarded in the same manner as it safeguards
        its own proprietary and confidential information of like character, and
        will not be divulged to third parties by it.  Information which is
        initially orally or visually submitted and identified at the time of
        initial disclosure as proprietary shall also be safeguarded only if the
        other party notifies it in writing, within ten (10) business days of
        such initial oral or visual disclosure, with a specific written
        identification of the proprietary information contained in such initial
        oral or visual disclosure.

        This Agreement shall not impose any obligation upon the receiving party
        with respect to any portion of the received information which (i) is
        now, or which hereafter, through no act or failure to act on the part of
        the receiving party, becomes generally known or available; (ii) is known
        to the receiving party at the time of receiving such information; (iii)
        is furnished to others by the disclosing party without restriction on
        disclosure; (iv) is hereafter furnished to the receiving party by a
        third party, as a matter of right and without restriction on disclosure;
        or (v) is independently developed by the receiving party without
        recourse to the received information, provided that the receiving party
        can demonstrate by written documentation that it developed such
        information independently.

        Each party agrees that upon written request from the other it will
        return any identified proprietary and confidential written material
        furnished to it which has not been provided in accordance with 

Date Revised: May 13, 1996                                                   2

        some business agreement transferring rights to such material, and will
        state in writing that no copy of such material has been provided to
        others or has been retained (except for one archival copy which each
        party may retain in locked legal files)."

6)      Article 10 SECRECY - sub-paragraph (c) - revise wording as follows:

        "This commitment shall terminate three (3) years from the Termination
        Date of this Agreement."

        following:

        "This Agreement may not be assigned by either party without the prior
        written agreement of the other party and any purported attempt to do so
        shall be null and void.  This Agreement shall, however, be binding upon
        and inure to the benefit of any successor in interest of a party hereto
        as a result of a merger or consolidation."

8)      Add a new Article 22 entitle "MACHINE RESCHEDULE" with wording as
        follows:

        "CALCOMP may, without incurring liability for any additional or
        increased costs resulting therefrom, make changes in the quantities of

        change is given to KTA no later than the period of time specified below
        as applicable to the percentage change in quantity."

        orders, for delivery during the notice period or in the subsequent six
        (6) month period provided that the delivery schedule for such six (6)
