            period. Motorola shall not be liable for any development costs 
            incurred or termination charges of any kind.

      10.4  If Parlex fails to maintain its position as a satisfactory 
            supplier by not remaining competitive in quality and delivery as 
            defined in this Agreement with other responsible suppliers or 
            potential suppliers of flexible circuits of substantially similar 
            prices, Motorola may terminate this Agreement without further 
            liability to Parlex by furnishing written notice of a termination 
            date no less than ninety (90) days after the date of the notice. 
            If, however, prior to such termination date, Parlex becomes 
            competitive, or demonstrates to Motorola's satisfaction its 
            capability of becoming competitive within an additional time 
            period selected by Motorola, the notice of termination shall be 
            withdrawn and this Agreement shall continue.

      10.5  If flexible circuits of significantly advanced design or 
            processing become available to Motorola, which are capable of 
            being used as a replacement of or in substitution for the 
            production of Flexible Substrate Assemblies being purchased 
            hereunder, Motorola may terminate this Agreement without further 
            liability to Parlex by furnishing written notice of a termination 
            date no less than one hundred eighty (180) days after the date of 
            the notice. If, however, prior to such termination date, Parlex 
            demonstrates to Motorola's satisfaction its capability of 
            producing and delivering Flexible Substrate Assemblies of the same 
            or comparable design or processing, at competitive prices in the 
            quantities required, the notice of termination shall be withdrawn 
            and this Agreement shall continue with respect to the Flexible 
            Substrate Assemblies of significantly advanced design or 
            processing.

      10.6  In the event of a material breach of this agreement, 
            Motorola or Parlex, as the case may be, shall give written notice 
            to the defaulting party of the breach and of the non-defaulting 
            party's intention to terminate this Agreement if the non-
            defaulting party is not, within thirty (30) days from and after 
            receipt of the written notice of default, provided with a plan of 
            corrective action and if substantial efforts to cure the default 
            in accordance with the plan are not made. If such breach is not 
            substantial corrected as provided above, the nondefaulting party 
            may terminate this Agreement by sending written notice to the 
            other party of such termination, whereupon this Agreement shall 
            terminate and the non-defaulting party, subject to the terms of 
            this Agreement, shall be entitled to pursue remedies provided by 
            law. In the event the nondefaulting party elects to terminate this 
            Agreement, the notice of termination must be sent to the 
            defaulting party within five (5) days after the expiration of the 
            thirty (30) day period mentioned above.

      10.7  Either party may terminate this Agreement on thirty (30) 
            days written notice without liability to the other party in the 
            event of the happening of any of the following with regard to that 
            other party: (a) ceases to function as a going concern, (b) makes 
            as assignment of the benefit of creditors, (c) becomes the subject 
            of any proceeding under any applicable bankruptcy, receivership, 
            insolvency or similar laws instituted by or against such party, 
            which proceeding is not dismissed as to such party within forty-
            five (45) days after it has been instituted, or (d) liquidates, 
            dissolves, sells substantially all of its assets, mergers or 
            consolidates.

12.0  General

      12.1  Neither party shall be liable for any failure to perform or 
            for any delay in performance of its obligations hereunder which is 
            caused by circumstances beyond its reasonable control, including 
            but not limited to acts of God or a public enemy, fires, storms, 
            floods, epidemics, quarantine restrictions, riots, insurrections, 
            explosions, accidents, war, labor disputes, transportation 
            embargoes, acts or failures to act of or by any government or 
            agency thereof, judicial action, or any act, neglect or default of 
            the other party. Each party shall promptly notify the other of the 
            existence of any excusable nonperformance or any delays and the 
            anticipated duration thereof.

      12.2  No delay on the part of either party in exercising any of 
            its respective rights hereunder or the failure to exercise the 
            same nor the acquiescence in or waiver of a breach of any term, 
            provision or condition of this Agreement shall be construed to 
            operate as a waiver of any such rights or acquiescence thereto, 
            except for the specific instance of delay, waiver or acquiescence.

      12.3  This Agreement and the rights and obligations hereunder may 
            not be assigned by either party without the prior written consent 
            of the other party.

      12.4  This Agreement is deemed to have been entered into in 
            Illinois, and its interpretation, construction and remedies for 
            its enforcement or breach are to be applied in accordance with the 
            laws of the State of Illlinois without reference to principles of 
            choice and conflicts of laws.

      12.5  Section and paragraph headings used in this Agreement are 
            for convenience only and are not to be deemed or construed to be 
            part of this Agreement.

      12.6  This Agreement does not create an agency, joint venture or 
            partnership between Motorola and Parlex. Neither party shall 
            impose or create any obligation or responsibility, express or 
            implied, or make any promises, representations or warranties on 
            behalf of the other party, other than as expressly provided 
            herein.

13.0  Dispute Resolution

      13.1  Motorola and Parlex will attempt to settle any claim or 
            controversy arising out of this Agreement through consultation and 
            negotiation in good faith and a spirit of mutual cooperation. If 
            those attempts fail, then the dispute will be mediated by a 
            mutually acceptable mediator to be chosen by Motorola and Parlex 
            within 45 days after written notice by either to the other 
            demanding mediation. Neither party may unreasonably withhold 
            consent to the selection of a mediator, and Motorola and Parlex 
            will share the costs of the mediation equally. By mutual 
            agreement, however, Motorola and Parlex may postpone mediation 
            until some specified but limited discovery about the dispute has 
            been completed. The parties may also agree to replace mediation 
            with some other form of alternative dispute resolution (ADR), such 
            as neutral fact-finding or a minitrial.

      13.2  Any dispute which cannot be resolved between the parties 
            through negotiation, mediation or other form of ADR within six 
            months of the date of the initial demand for it by one of the 
            parties may then be submitted to the courts for resolution. The 
            use of any ADR procedures will not be construed under the 
            doctrines of laches, waiver or estoppel to affect adversely the 
            rights of either party. And nothing in this section will prevent 
            either party from resorting to judicial proceedings if (a) good 
            faith efforts to resolve the dispute under these procedures have 
            been unsuccessful or (b) interim relief from a court is necessary 
            to prevent serious and irreparable injury to one party or to 
            others.

14.0  Entire Agreement

      This Agreement, together with the Appendices referred to herein 
      and the terms and conditions of Motorola's current standard purchase 
      order form, constitutes the entire Agreement and understanding of the 
      parties with regard to the matters covered and herein have merged all 
      prior and collateral representations, promises or conditions, whether 
      oral or written. No amendment or modification of any of the provisions 
      contained herein shall be binding upon either party unless made in 
      writing and signed by a duly authorized representative of each party.

IN WITNESS WHEREOF, each of the Parties hereto have caused this Agreement to

APPENDIX 4

                       Product Qualification Procedure
                       _______________________________

The following Product Qualification Procedure must be followed when the 
circuit construction's material or manufacturing process is modified. For all 
Purchase Orders placed by Motorola, Parlex must document in writing the 
circuit construction, materials and manufacturing process used to produce the 
order. This information will be treated as Parlex Confidential and will be 
distributed within Motorola on a need to know basis only. Once Parlex has 
produced pre-pilot samples any circuit construction changes, material changes 
or manufacturing process changes must be approved by Motorola prior to 
shipment of the changed flexible substrate assembly.

The procedure which will be used to evaluate and qualify new materials, 
manufacturing process or circuit constructions will be as follows:





    Activity                       Responsible             Time Duration
    ________                       ___________             _____________

                                                  
1.  New Material, Process or       Parlex or Motorola      Time 0
    Construction Idea
2.  Initial Evaluation Test        Parlex and Motorola     Time 0 + 2 weeks
3.  Schedule developed and         Parlex and Motorola     Time 0 + 4 weeks
    mutually agreed to
4.  Material, Process or           Parlex                  Time 0 + 14 weeks
    construction level
    qualification
5.  If required, product level     Motorola                Time 0 + 26 to 30 weeks
    design validation test
6.  If required, product level     Motorola                Time 0 + 44 to 48 weeks
    process validation test




The Production Flexible Substrate Assembly is considered preliminary qualified 
after successful completion of Product Level Design Validation Testing and 
final qualification after successful completion of Product Level Process 
Validation testing.

For each proposed material, process or construction change, this schedule will 
be reviewed to determine the appropriate qualification tests required. Once a 
Flexible Substrate Assembly is in production the qualification schedule will 
become dependent on Motorola's customer approval and may require additional 
time than detailed above.

Under no circumstances can a production approved Flexible Substrate Assembly 
be changed without Parlex obtaining prior approval from Motorola. Notification 
of changes to a production approved Flexible Substrate Assembly must be done 
in using the Supplier Request for Engineering Change Notice (SREA). The 
development schedule and qualification testing requirements may apply to any 
changes.


                                                                 April 8, 1993

marked at the time of disclosure as being "Confidential" or "Proprietary". 
Information disclosed orally or visually and identified at that time as 
Confidential shall be considered as "Confidential Information" if it is 
reduced to tangible form, marked Confidential, and transmitted to the 
receiving party within thirty (30) days after the oral or visual disclosure.

      2.  During the "Confidential Period" defined below, each party will use 
its best efforts to prevent its disclosure of the other party's "Confidential 
Information" for any purpose other than the aforesaid evaluation and 
development purposes, and to limit dissemination of the other party's 
"Confidential Information" to such of its employees who have a need to know 
for the aforesaid evaluation and/or development purposes. "Best efforts" with 
respect to any "Confidential Information" means at least that degree of care 
normally used by the receiving party to prevent disclosure to others of its 
own confidential information of similar importance, but in no case less than a 
reasonable degree of care.

      The "Confidential Period" shall mean five (5) years from the date of 
receipt of the "Confidential Information" or until such time as the 
information no longer qualifies as "Confidential Information" pursuant to 
Paragraph 4.

      3.  Except as may be provided in another written agreement between 
parties, neither party shall be obligated: to do business with the other 
party; to refrain from dealing with others in the above-identified subject 
area; or to begin, continue, or terminate any business venture.

      4.  Notwithstanding any other provisions of this Agreement, each party 
acknowledges that "Confidential Information" shall not include any information 
which: (a) is or becomes publicly known through no wrongful act on the 
receiving party's part; or (b) is, at the time of disclosure under this 
Agreement, already known to the receiving party without restriction on 
disclosure; or (c) is, or subsequently becomes, rightfully and without breach 
of this Agreement, in the receiving party's possession without any obligation 
restricting disclosure; or (d) is independently developed by the receiving 
party without breach of this Agreement; or (e) is furnished to a third party 
by the disclosing party without a similar restriction on the third party's 
rights; or (f) is explicitly approved for release by written authorization of 
the disclosing party.

      5.  Each party agrees to return to the disclosing party upon request, 
the devices, graphics, writings, and information in other tangible forms 
containing any of the "Confidential Information" referred to in Paragraph 1, 
and any copies of "Confidential Information".

      6.  No license, express or implied, in the "Confidential Information", 
is granted to either party other than to use the information in the manner and 
to the extent authorized by this Agreement.

      7.  This Agreement shall terminate on 3rd of March 1997 (the Termination 
Date). The obligations recited herein relating to information disclosed prior 
to the Termination Date shall survive such termination.

      8.  Each party acknowledges that it is not prohibited by the Office of 
Export Administration for the U.S. Department of Commerce from receiving 
technical information, know-how, data or other information, and it agrees not 
to export such information, or products incorporating it, to any prohibited 
country.

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

                                AMENDMENT TO
                      DEVELOPMENT AND SUPPLY AGREEMENT

      This amending agreement is made and entered into this 19th day of 
August, 1994 by and between Parlex Corporation, a Massachusetts corporation 
having a principal place of business at 145 Milk Street, Methuen, MA 01844 
("Parlex"), and Motorola, Inc., a Delaware corporation, by and through its 
Automotive and Industrial Electronics Group ("AIEG"), having a place of 
business at 4000 Commercial Avenue, Northbrook, IL 60062 U.S. A. ("Motorola").

      WHEREAS, the parties hereto made and entered into a written Development 
and Supply Agreement ("Agreement") dated April 13, 1993; and

      WHEREAS, the parties desire to amend the Agreement in certain respects.

      THEREFORE, Motorola and Parlex agree as follows:

      1.  Article 1. of the Agreement (Definitions) is amended by:

          (i)   modifying Paragraph 1.1 to read:

          1.1   Flexible Substrate Assembly: finished assembly panel 
                consisting of circuits made of either the Acrylic Adhesive-
                Based Flexible Circuit Construction or New Flexible Circuit 
                Construction, Rigidizer, and Motorola's circuit interconnect 
                design.

          (ii)  adding the following as Paragraph 1.5:

          1.5   Prototype: prototype, pre-pilot or other pre-
                production Flexible Substrate Assembly panel.
 
      2.  Paragraph 2.1.1 of the Agreement is amended by deleting 
          "January 1, 1994" and replacing it with "July 1, 1994".

      3.  Paragraph 2.2 of the Agreement is deleted in its entirety and 
          replaced with the following:

          2.2   Prototype and Pre-Pilot Assemblies

                2.2.1  Parlex shall build prototypes incorporating 
                       New Flexible Circuit Construction as needed by 
                       Motorola. Prototypes shall be delivered to Motorola 
                       for delivery to customers as samples and for 
                       evaluation and testing by Motorola. The purpose of the 
                       prototype evaluation and tests is to demonstrate the 
                       capabilities of the New Flexible Circuit Construction, 
                       and the parties thereby anticipate that desirable 
                       changes to the applicable specifications may be 
                       identified. Any proposed changes to the applicable 
                       specifications shall be made in accordance with 
                       paragraph 2.3.

                2.2.2  A standard prototype delivery shall be five 
                       (5) panels with a delivery lead time of four (4) 
                       weeks. The balance of any prototype order exceeding 
                       the standard delivery quantity of 5 panels, up to a 
                       maximum of two hundred fifty (250) circuits, shall 
                       have a delivery lead time of five (5) weeks. Delivery 
                       of that portion of prototype orders exceeding 250 
                       circuits will be scheduled as agreed by the parties. 
                       Parlex shall provide one standard delivery per week, 
                       as requested by Motorola.

                2.2.3  Motorola shall purchase prototypes 
                       incorporating new Flexible Circuit construction at a 
                       price equal to four (4) times the production price 
                       stated in Appendix 3 or at a lot charge of       *     
                       dollars, whichever is greater. Such price includes all 
                       prototype engineering and tooling costs, with the 
                       exception of electrical test tooling costs which shall 
                       be agreed by the parties. Further, such price is based 
                       on the standard delivery lead-time as described in 
                       paragraph 2.2.2 for prototype orders up to two hundred 
                       fifty (250) circuits. The following price premiums 
                       shall apply to three week, two week and one week 
                       deliveries: twenty five percent, fifty percent and one 
                       hundred percent, respectively.

      4.  Paragraph 3.1 of the Agreement is amended by deleting "January 
          1, 1994" and replacing it with "July 1, 1994".

      5.  Paragraph 3.2.1 of the Agreement is deleted and replaced with 
          the following:
        
          During the term of this Agreement, Parlex shall sell to 
          Motorola, and Motorola shall purchase from Parlex, Flexible 
          Substrate Assemblies in an amount * of AIEG's requirements as 
          measured in square footage. Motorola's purchase obligation in this 
          Paragraph 3.2 shall be limited to the extent that purchasers from 
          AIEG of Flexible Substrate Assemblies, or products incorporating 
          Flexible Substrate Assemblies, have approved other suppliers of 
          Flexible Substrate Assemblies as of the Agreement Date or require 
          other suppliers of Flexible Substrate Assemblies in the future.

      6.  The second sentence of Paragraph 3.2.2 of the Agreement is 
          deleted and replaced with the following:

          If so, Parlex shall sell to any such Motorola customer its 
          requirements for Flexible Substrate Assemblies on terms acceptable 
          to Parlex, except that warranty shall be identical to that herein 
          provided.

      7.  Article 3.0 of the Agreement is amended by adding the 
          following as Paragraph 3.9:

          3.9  FORECAST

          On or about December 15 of each year during the term of 
          this Agreement, Motorola will provide Parlex with a forecast of 
          AIEG's anticipated purchase volume for the following calendar year 
          of production for the purpose of establishing invoiced unit prices 
          as described in Paragraph 3.3. Performance to each forecast will 
          be reviewed by the parties on or about June 15 and on or about 
          December 15 of each year to determine if an adjustment of the 
          invoiced unit price is required to reflect unit volumes actually 
          purchased for that year.

      8.  Paragraph 3.5.1 of the Agreement is deleted and replaced with 
          the following:

          Parlex agrees not to sell to customers selling products in 
          the automobile industry the New Flexible Circuit Construction 
          developed hereunder for Motorola, or substantially identical 
          derivative flexible circuit, for one year following the initial 
          delivery to Motorola of satisfactory product level process 
          validation units of Flexible Substrate Assemblies incorporating 
          the New Flexible Circuit Construction, without first obtaining 
          Motorola's written permission. For the purpose of this Paragraph, 
          multi-layer circuits incorporating New Flexible Circuit 
          Construction shall not be considered to be "substantially 
          identical".

      9.  The first sentence of Paragraph 10.4 is deleted and replaced 
          with the following:

          If Parlex fails to maintain its position as a satisfactory 
          supplier by not remaining competitive in quality, price and 
          delivery as defined in this Agreement with other responsible 
          suppliers or potential suppliers of flexible circuits of 
          substantially similar prices, Motorola may terminate this 
          Agreement without further liability to Parlex by furnishing 
          written notice of a termination date no less than ninety (90) days 
          after the date of the notice.

      10. In all other respects, the Agreement shall continue in full 
          force and effect.

      11. This Amendment shall become effective on the date hereof.

      IN WITNESS WHEREOF, each of the parties hereto has caused this amendment 
to be signed by its respective duly authorized representative.
