At February 28, 1996, there were outstanding 11,285,266 shares of the Common
Stock of Registrant, and the aggregate market value of the shares held on that
date by non-affiliates of Registrant, based on the closing price ($20.31 per
share) of the Registrant's Common Stock on the Nasdaq National Market on that
date, was $178,075,639.  For purposes of this computation, it has been assumed
that the shares beneficially held by directors and officers of Registrant were
"held by affiliates"; this assumption is not to be deemed to be an admission by
such persons that they are affiliates of Registrant.

2.   DEVELOPMENT PROGRAM.

     2.1. During the Development Period, Spectra shall use all reasonable
          commercial efforts to develop Build Materials (jointly with
          Customer).  To the extent requested by Customer, Spectra will make
          changes to its Printheads and/or related equipment to adapt same for
          Rapid Prototyping given that all such requests are subject to
          Spectra's approval and funding will be negotiated in advance of any
          work by Spectra.  The Development Program shall be conducted at
          Spectra's facilities in Hanover, New Hampshire; provided, however,
          that Spectra personnel may from time to time meet with Customer as
          mutually agreed upon by the Parties pursuant hereto.  The parties
          shall consult on an on-going, hands-on basis with respect to all
          critical aspects of the Development Program including, without
          limitation, making revisions, amendments and/or improvements to the
          Specifications and the Development Program as may be reasonably
          required from time to time.

     2.2. BUILD MATERIAL.
          --------------

          2.2.1.    During the Development Period, the Parties will cooperate
                    in developing Build Materials that are compatible with the
                    Print Engine.  The goal is to develop Build Materials which

<PAGE>
                    maximize the demand for and use of Customer's Rapid
                    Prototyping Products which incorporate Spectra Technology. 
                    Accordingly, Customer shall have the primary responsibility
                    to propose formulations for and prepare new Build
                    Materials, and will provide samples thereof to Spectra for
                    testing with Printheads hereunder.

          2.2.2.    Customer shall provide samples of Build Materials to
                    Spectra in mutually agreed amounts of such material. 
                    Customer shall seek, on a reasonable efforts basis, to
                    formulate Build Materials which are generally not
                    hazardous.  Customer will list the components of each
                    sample and the desired characteristics of the end products
                    to be built using such Build Materials.  If any proposed
                    Build Material has, or reasonably should be expected to
                    have, ratings under the National Fire Protection
                    Association's scales of greater than (I) "1" for Health,
                    (ii) "2" for Flammability, (iii) "1" for Reactivity.  or
                    (iv) any special ratings (e.g., reacts with water, is an
                    oxidizer, etc.), Customer shall provide Spectra, in
                    advance, to the extent available, with any and all data in
                    Customer's possession relevant to properties of the Build
                    Material so that Spectra may make a good faith
                    determination if it can and is willing to accept and handle
                    such Build Materials.

          2.2.3.    Spectra shall exclusively use such samples for testing
                    under this Agreement and, if requested by Customer, shall
                    not attempt to chemically or otherwise analyze the
                    composition thereof unless Spectra is required to do so for
                    safety or disposal reasons.  Spectra shall not make any of
                    the samples or the formulations available to any third
                    party without Customer's express prior written
                    authorization.  The samples and all information with regard
                    thereto shall be governed by the confidentiality provisions
                    of Section 12 hereof.  Spectra and Customer shall each
                    appoint a coordinator to routinely discuss testing and
                    handling of Build Materials.  Prior to offering Build
                    Materials for sale commercially, Customer shall, at its own
                    expense, obtain any safety tests which the Customer deems
                    appropriate for the intended use.  Spectra is not
                    responsible for the safety and health of Build Materials
                    shipped to customers of Customer.

          2.2.4.    Spectra agrees to provide good faith efforts in
                    codevelopment of Build Materials.  In the first two years
                    of this Agreement, Spectra's obligation relative to
                    codevelopment of Build Materials shall be to dedicate at

          2.2.5.    Except as otherwise agreed in writing, each Party shall
                    bear its own expenses with respect to their activities
                    under Sections 2.1 and 2.2.

     2.3. DEVELOPMENT FEES.  In consideration of Spectra's performing the Work
          under phase 1 of the Development Program, Customer shall pay Spectra
          certain development fees (the "Development Fees") in the amounts set
          forth in the Payment Schedule included on Schedule 2 hereof, and upon
          Customer's acceptance of Deliverables set forth therein.  Such
          acceptance will not be unreasonably withheld.

     2.4. ENGINEERING MODIFICATIONS TO PRINTHEADS AND RELATED EQUIPMENT may be
          requested of Spectra by Customer from time to time during the
          Development Program in order to provide increased functionality for
          Rapid Prototyping, in which event the Parties shall negotiate in good
          faith payment, completion, and other terms.  Rights with respect to
          resulting Technology shall be governed by Section 5.

          work, trademark, trade secret, or proprietary or other information of
          any third party, and Spectra shall pay and discharge all judgments or
          decrees against Customer which result from those claims.  Spectra
          may, with Customer's consent (which Customer shall not unreasonably
          withhold), settle any such claim on terms of Spectra's choosing, if
          those terms do not conflict with this Agreement; provided, however,
          that Spectra shall not be obligated under this Section to the extent
          (i) Customer fails to give Spectra prompt notice of the claim,
          appropriate authority to settle or defend it, or the information and
          assistance necessary to conduct the defense, or (ii) the claims of
          infringement arise from or are based upon (A) Customer's or any third
          party's enhancements, modifications, alteration or implementation of
          a Spectra Product, or (B) the combination of a Spectra Product with
          any device Spectra did not directly furnish to Customer.

     5.2. Spectra represents that it has disclosed to Customer any patents
          relative to Ink Jet Rapid Prototyping of which it has knowledge as of
          the date hereof.  However, Spectra's obligations under this Section 5
          do not extend to claims concerning the use of Spectra Products in
          Rapid Prototyping.

     5.3. If (i) a court, agency, or arbitrator having jurisdiction holds that,
          or Spectra agrees in writing (which it shall not do without
          Customer's express written consent) with any third party that, any
          Spectra Product infringes a patent, copyright, mask work, or

<PAGE>
          trademark or involves an unlawful use of a third party's proprietary,

6.   OEM SUPPLY TERMS AND CONDITIONS.

     6.1. FORECASTS; PURCHASE ORDER

          6.1.1.    Customer will order Spectra Products through the issuance
                    of purchase orders at least ninety (90) days in advance of
                    the requested delivery dates.  All preprinted terms and
                    conditions on purchase orders are superseded entirely by
                    the terms and conditions of this Agreement.  Each purchase
                    order will adequately identify the Spectra Product ordered
                    by use of Spectra's product code set forth the requested
                    quantity, and specify the requested delivery method and
                    date.  Purchase orders must be in writing and may be sent
                    via facsimile to Spectra's then current facsimile number.

          6.1.2.    Upon receipt of any purchase order submitted in accordance
                    with this Agreement, Spectra will either: (i) accept the
                    order, which will establish the delivery date; or (ii)
                    within five (5) days after receipt of the Purchase Order
                    notify Customer of Spectra's inability to deliver Spectra
                    Product at the time or times requested.  In the event such
                    notice is not given within five (5) days, such Purchase
                    Order shall be deemed accepted.

          6.1.3.    Spectra Products will be delivered to Customer in packaging
                    reasonably acceptable to Customer, given shipment,
                    warehousing and storage requirements.  (Customer will
                    advise Spectra in writing of any special packing
                    requirements at the time of placing an order.) Delivery
                    will be made FOB Spectra's manufacturing, warehousing or
                    transshipment facility, freight proposed by Spectra {and

                    deferrable beginning ninety (90) days prior to scheduled
                    delivery date unless mutually agreed upon.  In general,
                    Spectra requires up to six (6) months advance notice to add
                    significant additional manufacturing capacity, and may not
                    be able to meet orders as a result of changes in or

<PAGE>
                    requirements in excess of those set forth in six-month

                    Spectra Hardware Product does not comply with any warranty
                    in Section 6.3 and Customer notifies Spectra of such

               7.1.4.3.  Customer has not cured the failure within thirty (30)

          10.2.1.   by either Party at any time if the other Party has breached

                    receipt of written notice thereof;

          10.2.2.   if either Party files for reorganization under the
                    Bankruptcy Act or it is adjudicated a bankrupt, or if a

                    creditors or if an involuntary bankruptcy petition is
                    brought against either Party and has not been discharged
                    within 30 days of the date on which it was brought, then
                    the other Party shall, without further notice, have the
                    immediate right to terminate this Agreement; or

          10.2.3.   by Customer for any reason or its convenience upon thirty
                    (30) days written notice to Spectra.

     10.3.     SURVIVAL; EFFECT OF TERMINATION.  Termination of the Agreement
               shall be without prejudice to any other remedies of either Party

               any reason, Sections 8.1, 8.2, 9.1, 10.3, 11.1, 12 (as provided
               in Section 12.8 ), 13.1 and 14.9 hereof shall survive and
               continue in full force and effect.  In the event of termination

               Customer's obligation to pay all amounts payable to Spectra

               Deliverables as of the date of termination, shall survive the
               termination of this Agreement for any reason.

11.  Arbitration.

     11.1.     ARBITRATION.  Any disputes hereunder shall be settled by binding
               arbitration conducted in accordance with the Arbitration Rules
               of the American Arbitration Association, and judgment upon the
               award rendered by the arbitrator(s) may be entered in any court
               having jurisdiction thereof.  Unless otherwise agreed, the
               arbitration shall be held in Boston, Massachusetts before a
               single arbitrator, mutually agreeable to the Parties; provided,
               however, that if the Parties cannot agree upon a single
               arbitrator within thirty (30) days following notice by one of
               the Parties to the other Party that it wishes to commence
               arbitration under this Section 11.1 arbitration shall be held
               before a panel of three arbitrators, one selected by Customer,
               one selected by Spectra, and the third selected by the two
               arbitrators chosen by the Parties.  The Parties shall each pay
               half of the costs of arbitration.  The arbitrators shall not
               award any punitive, exemplary, or other amounts in excess of
               actual damages.  The arbitrators' decisions shall be final and
               binding upon the Parties.  This arbitration is the exclusive
               procedure for dispute remediation of this Agreement.

12.  Confidentiality.

     12.1.     CONFIDENTIALITY.  Each Party shall maintain the confidentiality
               of any Confidential Information it receives from the other
               Party, and, except as expressly permitted in this Agreement,
               shall not disclose any such Confidential Information to third
               parties.  The Party receiving Confidential Information from the
               other Party shall use at least the same degree of care to
               maintain its confidentiality as it uses to maintain its own
               Confidential Information.

     12.2.     NO USE WITHOUT CONSENT.  The receiving Party shall not, except
               in connection with this Agreement, directly or indirectly use
               Confidential Information of the disclosing Party without the
               prior written consent of such disclosing Party.

     12.3.     EXCEPTIONS.  Notwithstanding the definition of Confidential
               Information or any other provision of this Agreement, a
               receiving Party shall not be required to treat any information
               received from the other Party as Confidential Information if and
               to the extent the receiving Party can establish by documentary
               evidence that: (i) such information is or becomes generally
               known or available by publication, commercial use or otherwise;
               (ii) such information was known by the receiving Party at the
               time of disclosure by the other Party and was not subject to any
               obligation of confidence; (iii) such information is rightfully
               communicated to the receiving Party by a third Party free of any
               obligation of confidence; or (iv) such information was developed

<PAGE>
               by employees or agents of the receiving Party independently of
               and without reference to Confidential Information of the other
               Party.

     12.4.     DISCLOSURE PURSUANT TO JUDICIAL OR GOVERNMENTAL REQUEST.  In the
               event that the receiving Party is ordered to disclose the other
               Party's Confidential Information pursuant to a judicial or
               governmental request, requirement or order, such receiving Party
               shall promptly, and in any event prior to disclosure, notify the
               disclosing Party and take reasonable steps to assist such
               disclosing Party in contesting such request, requirement or
               order or in otherwise protecting that Party's rights.

     12.5.     EXPORT.  Neither Party will export any Confidential Information
               of the other Party except as permitted by the laws and
               regulations of the United States and with the prior written
               consent of the disclosing Party.

     12.6.     INJUNCTIVE RELIEF.  Each Party hereby acknowledges that
               unauthorized disclosure or use of Confidential Information of
               the other Party could cause irreparable harm and significant
               injury that may be difficult or impossible to quantify. 
               Accordingly, a disclosing Party shall have the might to seek and
               obtain immediate injunctive relief from breaches of the
               provisions of this Section 12, in addition to any other rights
               and remedies it may have.

     12.7.     THIRD PARTY AGREEMENTS.  Spectra shall permit an individual(s)
               designated by Customer and approved by Spectra and bound by
               Section 12.1 hereof to review Spectra's agreements with the
               companies described in Section 4.2 hereof within thirty (30)
               days following the execution hereof (unless previously reviewed
               by such individual(s)).

     12.8.     SURVIVAL; EXPIRATION.  The provisions of this Section 12 shall
               survive the expiration or termination of this Agreement for a
               period of five (5) years.

13.  Force Majeure.

     13.1.     FORCE MAJEURE.  Neither Party shall be responsible to the other
               for failure to perform any of its obligations hereunder,
               provided such failure shall be caused by an act of God, war,
               riot, fire, explosion, flood, sabotage, inability to obtain fuel
               or power, governmental laws, regulations or orders, failure or
               destruction in whole or in part of machinery or equipment, or
               any other cause beyond the reasonable control of either Party,
               or labor trouble, strikes, lockout or injunction (whether or not
               such labor event is within the reasonable control of either
               Party).  Agreed upon delivery schedules shall be considered
               extended to a period of time not to exceed to the time lost
               because of any delay excusable under this provision, except that
               the offending Party shall use its reasonable efforts to minimize
               such delays.

14.  General.

     14.1.     ENTIRE AGREEMENT; WAIVERS.  This Agreement constitutes the
               entire agreement between the Parties hereto pertaining to the
               subject matter hereof and supersedes all prior and
               contemporaneous agreements, understandings, negotiations and
               discussions, whether oral or written, of the Parties with
               respect to such subject matter.  No waiver of any provision of
               the Agreement shall be deemed or shall constitute a waiver of
               any other provision hereof (whether or not similar), shall
               constitute a continuing waiver unless otherwise expressly
               provided nor shall be effective unless in writing and executed
               (i) in the case of a waiver by Spectra, by Customer and (ii) in
               the case of a waiver by Customer, by Spectra.

     14.2.     AMENDMENT OR MODIFICATION.  The Parties hereto may not amend or
               modify this Agreement except in such manner as may be agreed
               upon by a written instrument executed by Spectra and Customer.

     14.3.     INDEPENDENT CONTRACTORS.  The Parties agree that with respect to
               the business arrangement contemplated herein they shall both be
               acting as independent contractors and nothing herein contained
               or contained in this Agreement shall constitute the Parties as
               entering into a joint venture nor shall constitute either Party
               as the agent for the other for any purposes whatsoever.

     14.4.     SEVERABILITY.  In the event that any provision hereof would,
               under applicable law, be invalid or unenforceable in any
               respect, such provision shall (to the extent permitted under
               applicable law) be construed by modifying or limiting it so as
               to be valid and enforceable to the maximum extent compatible
               with, and possible under, applicable law.  The provisions hereof
               are severable, and in the event any provision hereof should be
               held invalid or unenforceable in any respect, it shall not
               invalidate, render unenforceable or otherwise affect any other
               provision hereof.

     14.5.     ASSIGNMENT; BINDING EFFECT.  This Agreement may not be assigned
               by either Party except to a third party in connection with the
               sale of all or substantially all the assets and business of the
               assigning Party or to a third party in connection with a merger
               or consolidation of the assigning Party with such acquiring
               Party that results in the exchange of a majority of the
               outstanding shares of the assigning Party for securities or
               other consideration issued or paid by such acquiring Party. 
               Notwithstanding the forgoing, Customer shall have the right to
               assign this Agreement to a purchaser of its Rapid Prototyping
               product line.

     14.6.     NOTICES.  Any notices or other communications required or
               permitted hereunder shall be sufficiently given if in writing
               and delivered personally or sent by telecopier (with a
