6.0       AIRCRAFT SCHEDULE

6.1       AIRCRAFT ARRIVAL
          In each Order, Buyer shall specify an estimated arrival date of the
          Aircraft.  Seller acknowledges that such date is only Buyer's best
          estimate and Buyer shall not be responsible for or be deemed to be in
          default under the Order if an arrival date is changed. In the event an
          arrival date of the Aircraft is different from the one set forth in 
          the Order, the parties shall negotiate a revised arrival and 
          Redelivery date. Notwithstanding the provision for an equitable 
          adjustment in Clause 11.0, "Changes," any change in arrival date

          inventory of the installed equipment, cargo and other appropriate
          items aboard the Aircraft.

          Following completion of the inspection and inventory, Seller will
          provide to Buyer and Customer written acknowledgment of receipt of the

          Seller shall conduct an operational ground check on the Aircraft in
          accordance with Seller's "Technical Order" criteria as may be
          applicable for the purpose of demonstrating to Customer and Buyer that
          the Fuel Tank System is operational.

7.2       AIRCRAFT RECEIPT FORM
          Seller shall redeliver the recorded inventory and the Aircraft to
          Customer after installation of the Fuel Tank System. Seller shall

          that may be required by Buyer, Customer or the FAA.

7.3       DELAY
          Redelivery of the Aircraft with the Fuel Tank System installed shall
          be strictly in accordance with the schedule and other requirements

          Buyer and 

                                       6


          confirm in writing of any circumstance that may cause a delay in
          Redelivery, stating the estimated period of delay and the reasons
          therefor. If requested by Buyer, Seller shall use additional effort
          including premium effort to avoid or minimize delay to the maximum
          extent possible. All additional costs resulting from such premium
          effort shall be borne by the party responsible for the delay, Nothing
          herein may be construed to prejudice any of the rights or remedies
          provided to Buyer in the applicable Order or by law.

7.4       LIQUIDATED DAMAGES

          Seller acknowledges that late delivery of Products will subject 
          Boeing to certain losses and damages, including possible stoppage 
          or interruption of the production line, utilization of additional 
          employee and other resources, damage to Boeing's reputation with 
          its customers and additional costs resulting from re-sequencing the 
          production line. The parties agree that such losses and damages 
          will be substantial, but extremely difficult and impracticable to 
          ascertain.

          Therefore, the parties agree that if Seller fails to deliver products
          in accordance with the schedule set forth in the Order, Seller will
          owe liquidated damages in the amount of ten thousand United States
          Dollars (U.S. $10,000.00) for each calendar day that seller is late in
          delivering products after the scheduled delivery date, up to a maximum
          of ten (10) calendar days.

          Such amounts shall be paid and received as liquidated damages and 
          not as a penalty. The parties acknowledge and agree that this 
          amount is presently a reasonable estimate of Boeing's anticipated 
          losses and damages considering all of the circumstances existing on 
          the date of the execution of this Agreement, including the 
          relationship of the amount of such liquidated damages to the degree 
          of harm to Boeing that reasonably could be anticipated. Further, 
          the parties expect that proof of actual damages would be 
          impractical or extremely difficult. Boeing shall be entitled, but 
          not obligated, to offset the amount of such liquidated damages 
          against any amount owed to Seller.

          In placing its initials in the space provided below, Seller expressly
          confirms the accuracy of the statement made above and fully
          understands the consequences of this provision at the time this
          Agreement was made.

          and any amounts owned by Boeing to Seller, regardless of whether any
          such deposit, amount, balance or other amount or payment is then due
          and owing.

     D.   TOOLING AND OTHER MATERIALS
          As compensation for the additional costs which Boeing will incur as a
          result of the actual physical transfer of production capabilities
          from Seller to Boeing or Boeing's designee, Seller shall upon the
          request of Boeing, transfer and deliver to Boeing or Boeing's

          not be deemed a waiver of the right to exercise any other. Nothing
          contained in this Agreement shall be construed to limit any right or
          remedy of Boeing now or hereafter existing at law or in equity.

14.0      EXCUSABLE DELAY
          If delivery of any Product is delayed by unforeseeable circumstances
          beyond the control and without the fault or negligence of Seller or of
          its suppliers or subcontractors (any and without the fault or
          negligence of Seller or of its Suppliers or subcontractors (any such
          delay being hereinafter referred to as "Excusable Delay"), the
          delivery of such Product shall be extended for a period to be
          determined by Boeing after an assessment by Boeing of alternate work
          methods. Excusable Delays may include, but are not limited to, acts of
          God, war, riots, acts of government, fires, floods, epidemics,
          quarantine restrictions, freight embargoes, strike or unusually severe
          weather, but shall exclude Seller's noncompliance with any rule,
          regulation or order promulgated by any governmental agency for or with
          respect to environmental protection. However, the above
          notwithstanding, Boeing expects Seller to continue production, recover
          lost time and support all schedules as established under this
          Agreement or any Order. Therefore, it is understood and agreed that
          (i) delays of less than two (2 days' duration shall not be considered
          to be Excusable Delays unless such delays shall occur within thirty
          (30) days preceding the scheduled delivery date of any Product and
          (ii) if delay in delivery of any Product is caused by the default of
          any of Seller's subcontractors or suppliers, such delay shall not be
          considered an Excusable Delay unless the supplies or services to be
          provided by such subcontractor or supplier are not obtainable from
          other sources in sufficient time to permit Seller to meet the
          applicable delivery schedules. If delivery of any Product is delayed
          by any Excusable Delay for more than three (3) months,

                                       17


          Boeing may, without any additional extension, cancel all or part of
          any Order with respect to the delayed Products, and exercise any of
          its remedies in accordance with GTA Section 13.2 provided, however,
          that Boeing shall not be entitled to monetary damages or specific
          performance to the extent Seller's breach is the result of an
          Excusable Delay.

15.0      SUSPENSION OF WORK
          Boeing may at any time, by written order to Seller, require Seller to
          stop all or any part of the work called for by this Agreement
          hereafter referred to as a "Stop Work Order" issued pursuant to this
          Section 15.0 On receipt of a Stop Work Order, Seller shall promptly
          comply with its terms and take all reasonable steps to minimize the
          occurrence of costs arising from the work covered by the Stop Work
          Order during the period of work stoppage. Within the period covered by
          the Stop Work Order (Including any extension thereof), but not to
          exceed thirty (30) days duration, Boeing shall either (i) cancel the
          Stop Work Order or (ii) terminate or cancel the work covered by the
          Stop Work Order in accordance with the provisions of GTA Section 12.0
          or 13.0 In the event the Stop Work Order is canceled by Boeing or the
          period of the Stop Work Order (including any extension thereof)
          expires, Seller shall promptly resume work in accordance with the
          terms of this Agreement or any applicable Order.

16.0      TERMINATION OR CANCELLATION AND INDEMNITY AGAINST SUBCONTRACTOR CLAIMS
          Boeing shall not be liable for any loss or damage resulting from any
          termination for Buyer's convenience pursuant to GTA Section 12.1,
          except as expressly provided in GTA Section 12.3 or any cancellation
          under GTA Section 13.0 except to the extent that such cancellation
          shall have been determined by Boeing and Seller to have been wrongful,
          in which case such wrongful cancellations hall be deemed a termination
          pursuant to GTA Section 12.1 and therefore shall be limited to the
          payment to Seller of the Amount or amounts identified in GTA Section
          12.37 As subcontractor claims are included in Seller's termination
          claim pursuant to GTA Section 12.3, Seller shall indemnify Boeing and
          hold Boeing harmless from and against (is) any and all claims, suits 
          and proceedings against Boeing by any subcontractor or supplier of 
          Seller in respect of any such termination and (ii) and any and all 
          costs, expenses, losses, and damages incurred by Boeing in connection
          with any such claim, suit or proceeding.

17.0      ASSURANCE OF PERFORMANCE
     A.   SELLER TO PROVIDE ASSURANCE
          If Boeing determines, at any time or from time to time, that it is not
          sufficiently assured of Seller's full, timely and continuing
          performance hereunder, or if for any other reason Boeing has
          reasonable grounds for insecurity, Boeing may request by notice to
          Seller, written assurance

                                      18

          matters affecting Seller's performance hereunder, that Seller is able
          to perform all of its respective obligations under this Agreement when
          and as specified herein. Each Assurance of Performance shall be
          delivered by Seller to Boeing as promptly as possible, but in any
          event no later than 15 calendar days following Boeing's request
          therefore and each Assurance of Performance shall be accompanied by
          any information, reports or other materials, prepared by Seller, as
          Boeing may reasonably request. Boeing may suspend all or any part of
          Boeing's performance hereunder if Boeing fails to receive an Assurance
          of Performance from Seller satisfactory in form and substance to
          Boeing.

     B.   Boeing may request one or more meetings with senior management or
          other employees of Seller for the purpose of discussing any request by
          Boeing for Assurance of Performance or any Assurance of Performance
          provided by Seller. Seller shall make such persons available to meet
          with representatives of Boeing as soon as may be practicable following
          a request for any such meeting by Boeing and Seller shall make
          available to Boeing any additional information reports or other 
          materials in connection therewith as Boeing may reasonably request.

          On delivery to Seller or manufacture of acquisition by it of any
          materials, parts, Tooling or other property (excluding the Aircraft),

          of and shall be responsible for any loss thereof or damage thereto. In
          accordance with the provisions of an Order, but in any event on
          completion thereof, Seller shall return such property to Buyer in the

          and except to the extent that such property has been incorporated in
          the Products delivered under such Order or has been consumed in the
          normal performance of work under such Order.

          Seller warrants to Boeing that it has good title to all inventory,
          work-in-process, tooling and materials to be supplied by Seller in the
          performance of its obligations under any Order ("Inventory")), and 
          that pursuant to the provisions of such Order, it will transfer to 
          Boeing title to such Inventory, whether transferred separately or as
          part of any Product delivered under the Order, free of any liens, 
          charges, encumbrances or rights of others.

20.0      PROPRIETARY INFORMATION AND ITEMS
          Boeing and Seller shall each keep confidential and protect from
          disclosure all (a) confidential, proprietary, and/or trade secret
          information; (b) tangible items containing, conveying, or embodying

                                      19


          such information; and (c) tooling obtained from and/or belonging to 
          the other  in connection with this Agreement or any Order 
          (collectively  referred to as "Proprietary Information and

          Information and Materials of the other only in the performance 
          of and for the purpose of this Agreement and/or any Order. 
          Provided, however, that despite any other obligations or 
          restrictions imposed by this Section 20.0, Boeing shall 
          have the right to use and disclose of Seller's Proprietary 
          Information and Materials as approved by Seller for the purposes 
          of testing, certification, use, sale, or support of any products 
          delivered under this Agreement, an Order, or any airplane, 
          including such an item; and any such disclosure by 
          Boeing shall, whenever appropriate, include a restrictive legend as 
          approved by Seller for suitable to the particular circumstances. 
          The restrictions on disclosure or use of Proprietary Information

          Boeing, sell or dispose of(as scrap or otherwise) any parts or 
          other materials containing, conveying, embodying, or made in 
          accordance with or by reference to any Proprietary Information and 
          Materials of Boeing. Prior to disposing of such parts of materials 
          as scrap, Seller shall render them unusable. Boeing shall have the 
          right to audit Seller's compliance with this Section 20.0 Seller 
          may disclose Proprietary Information and Materials of Boeing to its 
          subcontractors as required for the performance of an Order, 
          provided that each such subcontractor first assumes by written 
          agreement, the same obligations imposed upon Seller under this 
          Section 20.0 relating to Proprietary Information and Materials; and 
          Seller shall be liable to Boeing for any breach of such obligation 
          by such subcontractor. The provisions of this Section 20.0 are 
          effective in lieu of, and will apply notwithstanding the absence 
          of any restrictive legends or notices applied to Proprietary 
          Information and Materials; and the provisions of this Section 20.0 
          shall survive the performance, completion, termination or 
          cancellation of this Agreement or any Order This Section 20.0 
          supplements any and all other prior agreements or understandings 
          between the parties to the extent that such agreements or 
          understandings relate to Boeing's obligations relative to 
          confidential, proprietary, and/or trade secret information, or 
          tangible items containing, conveying, or embodying such 
          information, obtained from Seller and related to any Product, 
          regardless of whether disclosed to the receiving party before or 
          after the effective date of this Agreement.

22.0      INTEGRITY IN PROCUREMENT
          Boeing's policy is to maintain high standards of integrity in
          procurement. Boeing's employees must ensure that no favorable
          treatment compromises their impartiality in the procurement process.
          Accordingly, B Boeing's employees must strictly refrain from
          soliciting or accepting any payment, gift, favor or thing of value
          which could improperly influence their judgment with respect to either
          issuing an

          Order or administering this Agreement. Consistent with this policy,
          Seller agrees not to provide or offer to provide any employees of
          Boeing any payment, gift, favor or thing of value for the purposes of
          improperly obtaining or rewarding favorable treatment in connection
          with any Order or this Agreement. Seller shall conduct its own
          procurement practices and shall ensure that its suppliers conduct
          their procurement practices consistent with these standards. If Seller
          has reasonable grounds to believe that this policy may have been
          violated, Seller shall immediately

                                      21


          report such possible violation to the appropriate Director of Materiel
          or Ethics Advisor of Boeing.

23.0      INFRINGEMENT
          Seller shall indemnify, defend and save Boeing and Customers harmless
          from all claims, suits, actions, awards (including but not limited to
          awards based on intentional infringement of patents known to Seller at
          the time of such infringement, exceeding actual damages, and/or
          including attorney's fees and/or costs), liabilities, damages, costs
          and attorneys' fees related to the actual or alleged infringement of
          any United States or foreign intellectual property (including but not
          limited to any right in a patent, copyright, industrial design or
          semiconductor mask work, or based on misappropriation or wrongful use
          of information or documents) and arising out of the manufacture, 
          sale or use of Products by Boeing or Customers. Boeing and/or 
          Customers shall duly notify Seller of any such claim, suit or 
          action; and Seller shall at its own expense, fully defend such 
          claim, suit or action on behalf of Boeing and/or Customers. 
          Seller shall have no obligation under this Section 23.0 with 
          regard to any infringement arising from: (i) Seller's
          compliance with formal specifications issued by Boeing where 
          infringement could not be avoided in complying with such 
          specifications or (ii) use or sale of Products in combination 
          with other items when such infringement would not have occurred 
          from the use or sale of those Products solely for the purpose for 
          which they were designed or sold by Seller. For purposes of this 
          Section 23.0 only, the term Customer shall not include the United 
          States Government; and the term Boeing shall include The Boeing 
          Company (Boeing) and all Boeing subsidiaries and all officers, 
          agents, and employees of Boeing or any Boeing subsidiary. In no 
          event will Seller's liability hereunder extend beyond thirty-six 
          (36) months after First Delivery of product to Buyer.

          Seller shall maintain continuously in effect a property insurance
          policy covering loss or destruction of or damage to all property in
          which Boeing does or could have an insurable interest pursuant to this

          the foregoing in each case to the extent in the possession or under
          the effective care, custody or control of Seller, in the amount of
          full replacement value thereof providing protection against all perils
          normally covered in an "all risk" property insurance policy
          (including without limitation fire, windstorm, explosion, riot, civil
          commotion, aircraft, earthquake, flood or other acts of God). Any such
          policy shall be in the form and with insurers acceptable to Boeing 
          and shall (i) provide for payment of loss thereunder to Boeing, as 
          loss payee, as its interests may appear and (ii) contain a waiver of 
          any rights of subrogation against Boeing, its subsidiaries, and their
          respective directors, officers, employees and agents.

29.2      CERTIFICATE OF INSURANCE
          Prior to commencement of this Agreement, Seller shall provide to
          Boeing's Materiel Representative, for Boeing's review and approval,
          certificates of insurance reflecting full compliance with the
          requirements set forth in GTA Section 27.1. Such certificates shall be
          kept current and in compliance throughout the period of this Agreement
          and shall provide for thirty (30) days advanced written notice to
          Boeing's Materiel Representative in the event of cancellation,
          non-renewal or material change adversely affecting the interests of
          Boeing.

29.3      NOTICE OF DAMAGE OR LOSS
          Seller shall give prompt written notice to Boeing's Materiel
          Representative of the occurrence of any damage or loss to any property
          required to be insured herein. If any such property shall be damaged
          or destroyed, in whole or in part, by an insured peril or otherwise,
          and if no Event of Default shall have occurred and be continuing,
          then Seller may, upon written notice to Boeing, settle, adjust, or
          compromise any and all such loss or damage not in excess of Two
          Hundred Fifty Thousand Dollars ($250,000) in any one occurrence and
          Five Hundred Thousand Dollars ($500,000) in the aggregate. Seller may
          settle, adjust or compromise any other claim by Seller only after
          Boeing has given written approval, which approval shall not be
          unreasonably withheld.

30.0      RESPONSIBILITY FOR PERFORMANCE
          Seller shall be responsible for the requirements of this Agreement and
          any Order referencing this Agreement. Seller shall bear all risks of
          providing adequate facilities and equipment to perform each Order in
          accordance with the terms thereof. Seller shall include as part of its

                                      28


          subcontracts those elements of the Agreement which protect Boeing's
          rights including but not limited to right of entry provisions,
          proprietary information and rights provisions and quality control
          provisions. In addition, Seller shall provide to its subcontractors
          sufficient information to clearly document that the work being
          performed by Seller's subcontractor is to facilitate performance under
          this Agreement or any Order. Sufficient information may include but
          is not limited to Order number, GTA number or the name of Boeing's
          Materiel Representative. No subcontracting by seller shall relieve
          Seller of its obligation under the applicable Order.

30.1      SUBCONTRACTING
          Seller may not procure any Product, as defined in the applicable
          Order, from a third party in a completed or a substantially completed
          form without Boeing's prior written consent.

          Where required by the requirements of the Order, no raw material
          and/or material process may be incorporated in a Product unless: (a)
          Seller uses an approved source or (b) Boeing has surveyed and
          qualified Seller's receiving inspection personnel and laboratories to
          test the specified raw materials and/or material process. No waiver of
          survey and qualification requirements will be effective unless
          granted by Boeing's Engineering and Quality Control Departments.
          Utilization of a Boeing-approved raw material source does not
          constitute a waiver of Seller's responsibility to meet all
          specification requirements.

30.2      RELIANCE
          Boeing's entering into this Agreement is in part based upon Boeing's
          reliance on Seller's ability, expertise and awareness of the intended
          use of the Products. Seller agrees that Boeing and Boeing's customers
          may rely on Seller as an expert, and Seller will not deny any
          responsibility or obligation hereunder to Boeing or Boeing's customers
          on the grounds that Boeing or Boeing's customers provided
