                      SELEX COLOR MINI-ENGINE SUPPLEMENT

         SUPPLEMENT (this "Supplement") made effective as of January 2, 1995 to 
the Selex Mini-Engine OEM Agreement dated as of May 26, 1994, as amended by 
Amendment No. 1 made effective as of January 2, 1995 (the "Agreement") between 
SELEX SYSTEMS U.S.A. INC., a California corporation ("SSUI") and CALCOMP INC., a
California corporation ("Buyer").

         SSUI and Buyer desire to supplement the Agreement to set forth the 
terms and conditions pursuant to which Buyer shall purchase from SSUI units of a
newly developed component for incorporation into Buyer's color ink jet plotters.
For good and valuable consideration, the receipt and sufficiency of which are 
hereby acknowledged, the parties hereto hereby agree as follows:

     1.  For purposes hereof, the term "Color Equipment" means (i) certain items
comprising a mini-engine which are listed and described in Annex A hereto
(collectively, the "Color Component"), including (A) a certain engine controller
(the "Color Engine Controller") developed by Buyer pursuant to a Development
Agreement dated as of October 31, 1993 between Buyer and Copyer and (B) a
certain head driver (the "Head Driver"), (ii) the spare parts for the Color
Component as listed in Annex B hereto, and (iii) a print head and BJ color ink
tanks, in each case with such engineering changes as may be incorporated therein
under the provisions of paragraph 4 of the Agreement. The term "Color Equipment"
does not include any other items unless both parties agree in writing pursuant
to a separate negotiation.

     2.  SSUI agrees to sell units of the Color Equipment to Buyer, and Buyer 
agrees to purchase the same. It is Buyer's non-binding forecast that during the 
one (1) year period ending December 31, 1995, Buyer will purchase from SSUI 
approximately 9,000 units of the Color Component. Buyer agrees to purchase the 
Color Equipment only from SSUI. Except as otherwise expressly provided in this 
Supplement, the terms and provisions of the Agreement shall apply to the 
purchase and sale of Color Equipment hereunder, and references in the Agreement 
to the "Equipment," the "Component," the "Engine Controller" and "spare parts" 
shall be deemed for purposes hereof to include, respectively, the Color 
Equipment, the Color Component, the Color Engine Controller and spare parts for 
the Color Component.

     3.  Buyer may place purchase orders hereunder for the Color Equipment 
during the Color Equipment Ordering Period. For purposes hereof, the "Color 
Equipment Ordering Period" shall mean the period commencing on the date hereof 
and ending on the first March 31 to occur after either party hereto gives notice
to the other party that the ordering period hereunder shall terminate; provided,
                                                                       --------
that such


<PAGE>
 
notice is given at least sixty (60) days prior to the relevant March 31.  
Notwithstanding the foregoing, in no event shall the Color Equipment Ordering 
Period extend beyond the date on which the Agreement is terminated.

     4.   The prices set forth in Annex C hereto shall be applicable to Buyer's 
purchase orders for the Color Component which are placed during the one year 
period ending December 31, 1995.  SSUI may from time to time change the prices 
for the Color Component ordered thereafter on ninety (90) days prior notice to 
Buyer.

     5.   SSUI's current list and prices of spare parts for the Color Component,
and prices for the print head and the BJ color ink tanks, are set forth in Annex
D hereto and are applicable to Buyer's purchase orders for such items which are
placed during the one-year period ending December 31, 1995. SSUI shall have the
right to change the prices for any of these items ordered thereafter on ninety
(90) days prior written notice. Spare parts for the Color Component, the Print
Head and the BJ ink tanks may be ordered for five (5) years after expiration of
the Color Equipment Ordering Period.

     6.   Notwithstanding paragraph 3.B of the Agreement, SSUI shall deliver 
certain electronics of the Color Component (consisting of the Head Driver and 
the Color Engine Controller) to Buyer F.O.B. SSUI's designated New Hampshire 
area warehouse (which may be a Lockheed Commercial Electronics Co. warehouse), 
whereupon all risk of loss shall pass to Buyer.  Notwithstanding paragraph 
3.A(i) of the Agreement, the price of that portion of the Color Component which 
is delivered to Buyer in New Hampshire, as well as the prices of the Head Driver
and Color Engine Controller when ordered by the Buyer as spare parts, shall not 
be subject to change to reflect exchange rate fluctuations.

     7.   For purposes of paragraph 9 of the Agreement, the term "Engine 
Controller" as used therein shall be deemed to include not only the Color Engine
Controller but shall also include the Head Driver.

     IN WITNESS WHEREOF, the parties have signed this Amendment by their duly 
authorized representatives this 9th day of October, 1995.

              for obvious damage to Equipment where the claim has been
              disallowed by the relevant insurance carrier due to untimely
              notice by Buyer as required hereunder.
