                           PRODUCT PURCHASE AGREEMENT


         This Product Purchase Agreement is made and entered into as of the
__________ day of September, 1996, the "Commencement Date", by and between
Interscience Computer Corporation, a California corporation with its executive
offices located at 5171 Clareton Drive, Agoura Hills, California 91301
(hereinafter referred to as "Interscience") and OCE Printing Systems USA, Inc.,
a Delaware corporation with its principal place of business located at 5600
Broken Sound Boulevard, Boca Raton, Florida 33487 (hereinafter referred to as
"OPS").

                                 R E C I T A L S


         A. Interscience desires to sell products as specified in the attached
Exhibit A ("Products") to OPS.

         B. OPS desires to purchase said Products, for resale to current and
future customers of OPS.

         THEREFORE, in consideration of the mutual covenants and agreements
herein contained, and other good and valuable consideration, Interscience and
OPS hereby covenant and agree as follows:


                                A G R E E M E N T


            1.01 PURCHASE/SALE. During the term of this Agreement Interscience
shall sell to OPS and OPS shall purchase from Interscience, the Products
described in the attached Exhibit A.

            1.02 PURCHASE FORECASTING. Interscience will accept OPS's standard
purchase order for all OPS orders of Product. OPS's purchase order will specify
a delivery date. It is expressly acknowledged and agreed by both Interscience
and OPS, that any forecasts shall not be construed as firm commitments by either
party, but shall be used by Interscience for the sole purpose of estimating
Interscience's internal scheduling to allow for timely deliveries on any
purchase orders which may be issued by OPS.

            1.03 DELIVERY SCHEDULE. Should Interscience fail within seven (7)
days following receipt of a purchase order from OPS, specifying a delivery date,
to specify an alternative delivery date acceptable to OPS, Interscience shall be
deemed to have agreed to the delivery date specified in OPS purchase order.

            2.01 DEALER SOLICITATION. During the term of this Agreement,
Interscience agrees not to solicit any new distributors of the Product,
PROVIDED, HOWEVER, OPS must purchase not less than twelve thousand (12,000)
cartons of fusing agent from Interscience during any twelve (12) month period.

            3.01 DELIVERY. All shipments of Products by Interscience to OPS
shall be FOB, Interscience's California manufacturing facility, via OPS
designated carriers. Products will be packaged for shipment in accordance with
OPS specifications and instructions. Interscience shall perform and document its
quality inspection of the Products prior to shipment. Interscience will pay
freight charges for the return of empty canisters.

            4.01 PRICE AND PAYMENT TERMS. Prices paid by OPS to Interscience as
the purchase price for the Product are set forth in Exhibit A of this Agreement.
The price per carton set forth in Exhibit A of this Agreement shall not change,
except as provided for in this Paragraph 4.01 of this Agreement. NOTWITHSTANDING
THE FOREGOING, upon the furnishing of documented evidence by Interscience of an
increase in Interscience's cost of raw materials by an amount in excess of ten
percent (10%) over Interscience's cost as of the execution date of this
Agreement, Interscience shall have the opportunity to negotiate a new purchase
price for the Product



                                       1.

limited to the amount of the increase in Interscience's cost for raw materials.
Shipments shall be invoiced upon shipment from Interscience's manufacturing
plant in California. Payment terms shall be net thirty (30) days from receipt of
invoice.

            5.01 TERM AND TERMINATION. The initial term of the Agreement is
sixty (60) months commencing upon the Commencement Date. Thereafter, OPS may
extend this Agreement for an additional one (1) year on the same terms and
conditions and at the price per carton as set forth in Exhibit A of this
Agreement upon ninety (90) days written notice prior to the initial expiration
date of this Agreement.

Notwithstanding the foregoing; (a) either Interscience or OPS may terminate this
Agreement, or any order placed hereunder, immediately, without prior written
notice, if the other party shall be or become insolvent or subject to any
liquidation, receivership, bankruptcy, reorganization, or creditor's proceeding,
either voluntary or involuntary, which proceeding shall not have been dismissed
within ninety (90) days after the commencement thereof, (b) either party may, by
written notice to the other, terminate this Agreement, or any order placed
hereunder, if the other party substantially and materially defaults in the
performance of its obligation(s) hereunder and fails to remedy such default
within thirty (30) days of receipt of written notice thereof, (c) OPS may
terminate this Agreement, or any order placed hereunder, if Interscience fails
to deliver any Product within thirty (30) days of its confirmed delivery date.

            6.01  WARRANTY.  Interscience represents and warrants:

                  (a) each Product is free from defects in design, materials and
                  workmanship:

                  (b) each Product performs in accordance with Interscience's
                  published specifications; See exhibit B

                  (c) title to each Product sold hereunder shall be free of any
                  lawful security interest, lien, or encumbrance; and

                  (d) the Products sold hereunder do not infringe upon the
                  intellectual property or proprietary rights of any third
                  party.

                  THERE ARE NO OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

            6.02 REMEDY FOR BREACH OF WARRANTY. OPS agrees that OPS' primary
remedy for breach of warranty shall be Interscience's repair or replacement of
the defective Product(s). In the event Interscience does not repair or replace
defective Product(s) within thirty (30) days of written notice of a verified
claim of a defective Product by OPS, OPS may elect to receive a full refund of
the purchase price of the defective Product(s) in lieu of the repair/replace
remedy.

            7.01 LIMITATION OF LIABILITY. OTHER THAN CLAIMS UNDER SECTION 8.01
AND 9.01, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR
CONSEQUENTIAL, SPECIAL, INDIRECT OR INCIDENTAL DAMAGES.

            8.01 INTELLECTUAL PROPERTY INDEMNITY. Interscience represents to OPS
that, to the best of Interscience's knowledge, neither Products provided
pursuant to this Agreement, nor the use thereof, violates or infringes upon any
U.S. patent, copyright, trade secret, or any other right of a third party
("Intellectual Property Right"). In the event of any action brought against OPS
in which infringement of an Intellectual Property Right is claimed, Interscience
will defend or settle the claim at its own expense, and indemnify OPS against
any expenses, cost or damages incurred by OPS on account of such claim, but such
defense, settlement and payment are conditioned on the following:

            (a) Interscience is notified of any claim promptly after OPS becomes
aware of any such claim;

            (b) OPS provides Interscience with all information reasonably
available to OPS; and

            (c) OPS provides Interscience with such assistance as may be
reasonably necessary to facilitate the settlement or defense of such claim.




                                       2.

<PAGE>   3
            8.02 CLAIM ALTERNATIVES. In the event such a claim occurs, or in
Interscience's sole opinion, is likely to occur, Interscience will, at its
option and expense, either procure for OPS the right to continue to market the
Products or replace or modify the Products so that they no longer infringe. If
despite the reasonable efforts of Interscience, neither alternative is feasible,
Interscience will accept return of the infringing Products for full refund,
without charge or penalty.

            8.03 LIMITATIONS ON INDEMNIFICATION. Interscience shall not
indemnify OPS against any claim of infringement arising out of the use or sale
of Products in combination with equipment, alterations, attachments or software
not supplied by Interscience.

            8.04 PARAGRAPH 7.01 NOT APPLICABLE. The limitations set forth in
Paragraph 7.01 of this Agreement are not applicable to the limitations on
liability as it pertains to indemnification as to any claims to patent
infringement.

            9.01 INDEMNIFICATION OF OPS. Interscience shall indemnify and hold
harmless OPS against any liability, damage or expense which OPS may sustain,
incur or be required to pay, arising out or in connection with claims for
personal injury or damage to real or tangible personal property resulting from
any negligent action or inaction or willful misconduct of Interscience, a person
employed by Interscience, or any of its subcontractors in performance of this
Agreement; provided that:

                  (a)   Interscience is notified of any claim promptly after OPS
                        becomes aware of it; and

                  (b)   OPS gives Interscience information reasonably available
                        and assistance reasonably necessary to facilitate the
                        settlement or defense of such claim.

                  Interscience's indemnity obligation under this section shall
be reduced to the extent by which the liability, damage or expense results from
the negligence or misconduct of employees of OPS.

                  No limitation of liability provision of this Agreement shall
apply to the indemnification provided by this Paragraph.

           10.01 AGENCY CERTIFICATIONS. Interscience warrants that all Products
provided hereunder are certified to be in compliance with applicable safety and
environmental laws and regulations promulgated by federal and state authorities.
Products shall be labeled accordingly and Interscience shall provide copies of
such certifications upon request.

           11.01 TRANSFER OF RIGHTS. OPS acknowledges that Interscience has
developed certain expertise and information regarding the production, bottling,
and use of HCFC 141-b as a fusing agent in the cold fusion printing process
("HCFC Information") including, but not limited to, the composition and
production of the fusing agent, canister, and valves. In July 1994, Interscience
was awarded U.S. patent number ("5,333,042") entitled Cold Fusing Agent.
Interscience has incurred significant costs in acquiring, developing, perfecting
and protecting the HCFC Information. OPS is desirous of having access to the
HCFC information should Interscience no longer produce and/or sell HCFC 141-b,
should Interscience terminate this Agreement prior to the end of its term (other
than due to a material, uncured default by OPS), or if ICC is unable to make
timely delivery of Products after notice as provided for herein. Accordingly,
Interscience will transfer its rights with respect to the HCFC information to
OPS as follows:

                  (a) Should Interscience cease production, sales and
distribution of HCFC 141-b for use as a fusing agent in the cold fusion printing
process to all of its customers such that Interscience no longer has any
business activities relating to HCFC 141-b and its printing applications for a
period of ninety (90) continuous days, unless such cessation of production is
the result of:

                      (1)   Materials shortage, through no fault of
                            Interscience;
                      (2)   A natural disaster or act of God;
                      (3)   An armed conflict making it difficult or impossible
                            to manufacture the Product; or



                                       3.

<PAGE>   4
                      (4)   Governmental decree, statute, ordinance or order
                            preventing Interscience from manufacturing or
                            delivering the Product;

or should Interscience be unable to deliver Products of a sufficient quality to
OPS and if Interscience is unable to cure any quality issue related to the
Products after three (3) months written notice from OPS given after an
arbitration determination made in accordance with Paragraph 11.01(b) below, then
in such event for valuable consideration, the receipt and sufficiency of which
are hereby acknowledged by Interscience, shall transfer any and all rights
including and related patent rights, proprietary or otherwise, which
Interscience may have in HCFC information to OPS.

                  (b) Should a dispute arise between Interscience and OPS
concerning the quality of the Products delivered to OPS, then such a dispute
shall be submitted to binding arbitration and mediation under the rules of the
Judicial Arbitration and Mediation Service ("JAMS").

           11.02 SUPPORT. In the event customers of OPS experience difficulties
or poor performance using the Product and such cannot be remedied by OPS
technical support personnel, Interscience agrees to provide on-site support in
the form of experienced Interscience personnel, at Interscience's expense, to
assist OPS and OPS's customers in resolving such problems.

           11.03 PRODUCT AND GENERAL LIABILITY INSURANCE. Interscience shall
maintain and provide proof of product and general liability insurance coverage
of no less than one (1) million dollars ($1,000.000.00) per occurrence with OPS
named as an additional insured. Each such insurance policy shall bear an
endorsement that such insurance shall be primary and shall not be cancelled
without thirty (30) days prior written notification to OPS.

           12.01 ARBITRATION AND MEDIATION. All controversies or claims arising
out of, or relating to this Agreement, or the breach thereof shall be settled by
arbitration and Mediation in the City of Los Angeles. California in accordance
with the rules of the Judicial Arbitration and Mediation Service ('JAMS'), and
judgment upon the award rendered by the Arbitrator(s) may be entered in any
court having jurisdiction thereof. Nothing herein, however, shall prevent either
party from resorting to a court of competent jurisdiction in those instances
where injunctive relief may be appropriate.
