        estimate shall be subject to adjustment from time to time.  Any such
        adjustment is not a change under GTA Section 10.0.

12.6    VALUE ENGINEERING, WEIGHT REDUCTION, LEAN MANUFACTURING AND RAW MATERIAL
        COST IMPROVEMENT

12.6.1  VALUE ENGINEERING
        Seller may from time to time submit proposals to Boeing to change
        drawings, designs, specifications or other requirements that:

        a.  decrease Seller's performance costs; or

        b.  produce a net reduction in the cost to Boeing of installation,
            operation, maintenance or production of the Product.

        Provided, that such change shall not impair any essential functions or
        characteristics of the Products or Tooling.

12.6.1.1    SUBMISSION OF PROPOSAL
            Proposals shall be submitted to Boeing's Materiel Representative. 
            Boeing shall not be liable for any delay in acting upon a proposal. 
            Boeing's decision to accept or reject any proposal shall be final. 
            If there is a delay and the net result in savings no longer
            justifies the investment, Seller will not be obligated to proceed
            with the change.  Seller has the right to withdraw, in whole or in
            part, any proposal not accepted by Boeing within the time period
            specified in the proposal.  Seller shall submit, as a minimum, the
            following information with the proposal:

            a.      description of the difference between the existing
            requirement and the proposed change, and the comparative advantages
            and disadvantages of each;

            b.      the specific requirements which must be changed if the
            proposal is adopted;

            c.      the cost savings and Seller's implementation costs;

            d. Each proposal shall include the need dates for engineering
               release and the time by which a proposal must be approved so as
               to obtain the maximum cost reduction.


                                      5



12.6.1.2    ACCEPTANCE AND COST SHARING
            Boeing may accept, in whole or in part, any proposal by issuing a
            change order.  Until such change has been issued, Seller shall
            remain obligated to perform in accordance with the terms and
            requirements of the original Order as written.  Boeing and Seller
            shall share the savings as follows:

               (50%) savings to Boeing;
               (50%) savings to Seller.

            Seller shall include with each proposal verifiable cost records and
            other data as required by Boeing for proposal review and analysis.

            Each party shall be responsible for its own implementation costs,
            including but not limited to non-recurring costs.

12.6.1.3    COST SAVINGS COMPUTATION
            A change order shall be issued by Boeing and the unit price shall be
            reduced in an amount equal to the savings portion attributable to
            Boeing as set forth above.  The applicable unit price as set forth
            in Attachment 1 Statement of Work shall be amended to reflect such
            change.



               EXAMPLE:
               --------
                                               
               Current Price:                     $600.00
               Proposed Cost Savings:             $100.00/unit
               Boeing's Percentage:               50.0%
               Seller's Percentage:               50.0%

            STEP BY STEP COMPUTATION:
            1. $100.00 unit savings x 50.0% Boeing's percentage of savings =
               $50.00 Boeing savings.

            2. $100.00 unit savings x 50.0% Seller's percentage of savings =
               $50.00 Seller savings.

            3. Net affect to the unit cost = $50.00

               New Unit Price For Units - $550.00

12.6.2  WEIGHT REDUCTION PROPOSALS
        Seller is encouraged to submit proposals to Boeing that reduce the
        Product's weight without impairing any essential functions or
        characteristics of the Product.

        Seller shall submit such proposals in accordance with SBP Section 12.6.1
        above.  The amount of any costs or savings that result from a weight
        reduction proposal shall be agreed by Boeing and Seller.  Seller shall
        include with each proposal verifiable cost records and other data as
        required by Boeing for proposal review and analysis.

        Boeing may accept in whole or in part, any such proposal by issuing a
        change order to the applicable Order.

12.6.3  LEAN MANUFACTURING/PROCESS IMPROVEMENT
        Boeing and Seller agree to work together to identify areas of
        improvement which affect the manufacturing and assembly process at
        Seller's facility and/or Seller's subcontractor's


                                       6



        facilities. Manufacturing and assembly processes include but are not 
        limited to inventory turn rates, leadtime reductions, contracting
        strategies, setup reductions and lot size reductions. Boeing and 
        Seller agree to use the following metrics to evaluate improvement:
        i) Inventory Turns, defined as Annual Costs of Goods Sold/Inventory
        Value; ii) Productivity, defined as Annual Sales/Average Employee
        Count; and, iii) Asset Turnover, defined as Annual Sales/Total Assets.
        Additional metrics may be added and evaluated as agreed to by the
        parties. Where Boeing and Seller can identify areas of improvement,
        beyond those previously anticipated, identified and documented in
        the contract price, the parties will determine the amount of savings
        which will result from the improvements and share the savings as set
        forth in 12.6.1.2 above. Where a savings is identified and documented,
        the parties agree to reduce the Product unit price by that amount
        apportioned to Boeing as identified above.

12.6.4  RAW MATERIAL COST IMPROVEMENT
        In the event Boeing implements a program to address raw material 
        issues affecting the subcontractor base, Seller agrees to support 
        Boeing by identifying areas of improvement involving raw materials.
        When requested by Boeing, Seller shall identify usage, leadtime,
        contractual impediments or any other factor which may affect 
        Boeing's ability to implement raw material program improvements. 
        Boeing's program to improve leadtime and price for raw material is
        intended to support all divisions, subsidiaries and affiliates
        of The Boeing Company.

        Where savings are identified and documented, the parties agree to 
        reduce the Product's unit price by the corresponding reduction in
        raw material price plus the applicable reduction in the corresponding
        mark-ups. These reductions shall be incorporated on the first delivery
        of applicable Product(s) which incorporate the revised pricing for raw
        material or as otherwise agreed to by the parties in writing.

        The implementation of these programs by Boeing and Seller's 
        participation in these programs shall not impair, prejudice or relieve
        Seller of its obligations under any applicable Order.

                   PRECIOUS METALS ABNORMAL ESCALATION CHARGES

Abnormal escalation adjustment clauses for precious metals used in the 
manufacture of Seller's products shall be in effect for this contract. The 
purpose of such clauses is to protect Supplier and Buyer from extreme price 
fluctuations in the precious metals used to plate electrical contacts. As 
such, the following clauses shall be in effect during the period of this 
contract for determining price adjustments, which shall occur quarterly, for 
such extreme fluctuations.

RHODIUM

The following concept will be used for calculating abnormal escalation 
adjustments for the rhodium plated electrical contacts. The amount of rhodium 
in each contact is as follows:



               Part Number          Rhodium Content (grams)
               ---------------------------------------------
                                
               BACC47CN3                  .00314000
               BACC47CN3B                 .00314000
               BACC47CP2T                 .00246688
               BACC47CP2TB                .00246688
               BACC47CP3T                 .00373080


The base price of rhodium shall be $20.81 per gram with a ceiling price of 
$35/gram and a floor price of $6.62.  Adjustments will be made when the price 
of rhodium extends beyond the ceiling or floor and will be adjusted from the 
base price. The following formula shall be used for price adjustments:

    (Monthly weighted average rhodium price - base rhodium price) x rhodium 
    content (grams) x quantity of electrical contacts delivered in the 
    referenced quarter.

    A resulting positive number indicates that Boeing owes Tri-Star, while a 
    resulting negative number indicates that Tri-Star owes Boeing.

As soon as practical after each quarter delivery date (March 31, June 30, 
September 30, December 31), Supplier will send to Buyer an assertion for the 
rhodium adjustment for that quarter. Documentation provided to Buyer shall 
include:

    - Part number
    - Quantity of parts
    - Price adjustments for that part number
    - All invoices for rhodium purchased in the delivery month
    - Rhodium cost used in the adjustment formula

As soon as the data can be verified, Buyer will issue a non-receivable 
purchase order for the cost adjustment.

                                                  SPECIAL BUSINESS PROVISIONS
EXAMPLES:

RHODIUM PRICE INCREASE:
Current month weighted average price: $35.00/gr.
Base price: $21.81/gr.
Part deliveries. BACC47CN3 = 18,000
Rhodium content: .003140 gr.

Adjustment: ($35.00 - $21.81) x .003140 x 18,000 = $745.50 Boeing owes Tri-Star

RHODIUM PRICE NO CHARGE
Current month weighted average price: $33.50/gr.
Base price: $21.81/gr.

            Or

Current month weighted average price: $7.25/gr.
Base price: $21.81/gr.

Adjustment: Current prices in the above two scenarios are neither above 
$35.00/gr. nor below $6.62/gr. therefore, no price adjustment.

RHODIUM PRICE DECREASE
Current month weighted average price: $4.25/gr.
Base price: $21.81/gr.
Part deliveries: BACC47CN3 = 18,000
Rhodium content: .003140 gr.

Adjustment: ($4.25 - $21.81) x .003140 x 18,000 = -$992.49 Tri-Star owes Boeing

GOLD

The following concept will be used for calculating abnormal escalation 
adjustments for the gold plated electrical contacts. The amount of gold in 
each contact is as follows:

The base price of gold shall be $320 per troy ounce with a ceiling price of 
$425/troy oz. and a floor price of $215. Adjustments will be made when the 
price of gold extends beyond the ceiling or floor and will be adjusted from 
the base price. The following forumula shall be used for price adjustments:

    (Monthly weighted average gold price - base gold price) x gold content
    (troy oz.) x quantity of electrical contacts delivered in the referenced 
    quarter.

    A resulting positive number indicates that Boeing owes Tri-Star, while a
    resulting negative number indicates that Tri-Star owes Boeing.

As soon as practical after each quarter delivery date (March 31, June 30, 
September 30, December 31), Supplier will send to Buyer an assertion for the 
gold adjustment for that quarter. Documentation provided to Buyer shall 
include:

    - Part number
    - Quantity of parts
    - Price adjustments for that part number
    - All invoices for gold purchased in the delivery month
    - Gold cost used in the adjustment formula

As soon as the data can be verified, Buyer will issue a non-receivable 
purchase order for the cost adjustment.

EXAMPLES:

GOLD PRICE INCREASE
Current month weighted average price: $550.00/oz.
Base price: $320/oz.
Part deliveries: BACC47CNIS - 18,000
Gold content: .0000717 oz.

Adjustment: ($550.00 - $320.00) x .0000717 x 18,000 = $296.84 Boeing owes 
Tri-Star.

GOLD PRICE NO CHARGE
Current month weighted average price: $395/oz.
Base price: $320/oz..

           Or

Current month weighted average price: $225/oz.
Base price: $320/oz.

Adjustment: Current prices in the above two scenarios are neither above 
$425/oz. nor below $215/oz. therefore, no price adjustment.

GOLD PRICE DECREASE
Current month weighted average price: $175.00/oz.
Base price: $320/oz.
Part deliveries: BACC47CNIS = 18,000
Gold content: .0000717 oz.

Adjustment: ($175.00 - $320.00) x .0000717 x 18,000 = $187.14 Tri-Star owes 
Boeing
