The timely implementation of the Continuous Cost Improvement Process (CCIP) is a
material duty of the Seller.  The CCIP is an ongoing, year-after-year plan to
achieve cost reductions.  The goal is to work together to reduce prices, while
maintaining or improving market share, margins, profits, and quality levels, and
meeting schedule and other contractual requirements.  The implementation of the
CCIP requires establishing cost improvement targets, developing and agreeing on
a cost improvement plan, implementation of the plan by the Seller, regular
review and status reporting with the Procurement Representative, appropriate
support from the Procurement Representative, and corrective action as necessary
to meet the cost improvement targets.

Boeing may assist Seller in this effort in the areas such as Lean Manufacturing,
Advanced Quality System, the Accelerated Improvement Workshop (AIW), value
engineering and other initiatives.  Seller is not limited to the Boeing
initiatives and may implement any improvement consistent with the requirements
of the orders.

     B.   Reduce Boeing's product weight without impairing any essential
          functions or characteristics of the product;

     C.   Decrease Seller's costs or produce a net reduction in the cost to
          Boeing of installation, operation, maintenance or production of the
          Product; and/or improve producibility, reliability, expected life, or
          maintainability of the product.

Proposed changes shall not impair any essential functions or characteristics of
the Products or Tooling.

12.6.2.1  Submission of Cost Reduction Proposal

Proposals shall be submitted to Boeing's Procurement Representative.  Boeing
shall not be liable for any delay in acting upon a proposal.  Boeing's decision
to accept, postpone, or reject any proposal shall be final.  If there is a delay
and the net result in savings no longer justifies the investment, Boeing and
Seller will not be obligated to proceed with the initiative.  Seller has the
right to withdraw, in whole or in part, any proposal not accepted by Boeing
within the time period specified in Seller's 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 advantage 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.  An implementation schedule, including need dates for any Boeing actions
         and the time by which a proposal must be approved so as to obtain the
         maximum cost reduction.

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.

12.6.2.2  Acceptance and Cost Sharing

Boeing may accept, in whole or in part, any continuous improvement initiative
proposal by issuing a change order.  Until such change has been issued, Boeing
and Seller shall remain obligated to perform in accordance with the terms and
requirements of the Order.  Where Boeing and Seller 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.  Where a saving is
identified and documented, the parties agree to reduce the Product unit price.
Seller suggestions disapproved by Boeing may be given due consideration in
achievement of cost reduction goals.

                                 -------------

Parties
-------

The Seller is The Boeing Company, acting through its agent, TMX.  The Customer
is a Boeing subcontractor, at any tier, who is manufacturing a product in
support of a Boeing requirement.

Sales
-----

All materials to be furnished by Seller are to be within the limits and the
sizes published by Seller and subject to Seller's standard tolerances for
variations.  Seller will warrant that all materials to be supplied will conform
to the descriptions contained herein and on the face of the purchase order and
that Seller will convey good title to any such materials free from any security
interest, or other lien or encumbrance held by any other party and unknown to
the customer.  THERE IS NO WARRANTY OF MERCHANTABILITY OR FITNESS AND SELLER
WILL MAKE NO OTHER EXPRESS OR IMPLIED WARRANTIES EXCEPT AS STATED HEREIN.
Seller will not be liable for any incidental or consequential damages for any
breach of warranty, express or implied.  Seller's liability and the Customer's
sole and exclusive remedy will be limited at Seller's option either to (a)
return of the materials and repayment of the purchase price, or (b) replacement
of nonconforming materials upon return thereof to Seller.  The Customer shall be
required to notify Seller in writing of any claim of breach of warranty and no
materials shall be returned to Seller by the Customer without Seller's consent.

Payment Terms
-------------

The following payment processes will be followed for material sold to Customer
by Seller.  All payments shall be in United States Dollars.

DEBIT PROCESS
-------------

The debit process will be used in all circumstances where the Customer has an
account with the Seller.  The amount due is the quantity shipped multiplied by
the unit price, plus the price for any value added services.  The amount due
will be collected by the Seller's applying a debit to the Customer's account.
Payment is due on the net thirtieth (30th) day from the scheduled delivery date.
The debit will be applied to the Seller's account on the payment due date.  If
the debit amount exceeds the amount outstanding on the Customer's account, the
Customer will remit to The Boeing Company the amount due beyond the debit
payment due date. The foregoing debit process does not apply to Sellers who are
only performing under orders issued by the Tulsa Division of the Boeing
Commercial Airplane Group.

                                                     SPECIAL BUSINESS PROVISIONS

INVOICE PROCESS
---------------

The invoice process will be used for Customers not currently making direct sales
to Boeing; foreign countries governed by MITI laws and regulations (currently
Australia, Brazil, China, India, Japan, and Korea), and orders issued by the
Tulsa Division of the Boeing Commercial Airplane Group.  The amount due is the
quantity shipped multiplied by the unit price, plus the price for any value
added services.  Payment is due on the net thirtieth (30th) day after the date
of Seller's invoice, which shall be issued on the day following the date of
shipment.

LATE PAYMENT CHARGES
--------------------

Payments due Seller representing undisputed charges for material and services
that are not paid within forty-five (45) days after the date of Seller's invoice
or within fifteen days after any remittance due to Seller under the debit
process will be subject to a late payment charge.  Such charge will be computed
monthly using an annual rate of interest publicly announced by Citibank N.A. New
York, New York, as its prime rate in effect on the fifteenth (15th) day of the
month, as adjusted month to month, plus two percent (2%).  Such rate will be
applied on the basis of a 365-day year against the undisputed past due amount,
commencing on the forty-sixth (46th) day (or 16th day in the debit process)
after the invoice date and continuing until payment is received by Boeing.

DEBIT/INVOICE DISPUTE PROCEDURE
-------------------------------

Customer may dispute payment amounts due provided that (1) Customer contacts
Seller within 25 days of the date of the debit/ invoice, (2) Customer provides a
complete reason as to the dispute.  If the action is Seller's to resolve, late
payment charges will not be assessed on amounts that are under dispute.  Once a
dispute has been resolved, payment terms will be net 30 days from the date of
resolution.

FAILURE TO PAY
--------------

In the event Customer fails to make payments when due, Seller reserves the right
to assert whatever remedies it may have under law, including setoffs against
amounts due from Seller to Customer on other contracts.  In such an event,
Seller may, with respect to future orders, require full payment in advance or
otherwise alter the terms of payment specified earlier.

between Seller and Boeing locations unless otherwise agreed) at an agreeable
time.   The detail of the CPR's will be defined at a later date between Boeing
and Seller.   When they are defined, this attachment 9 will be updated.

                                                     SPECIAL BUSINESS PROVISIONS

                        QUALITY ASSURANCE REQUIREMENTS

A10.1  Quality System

All work performed under this SBP shall be in accordance with the following:

A.  Document D1-9000 Rev A., "Advanced Quality System", Section 1 and Section 2
    Advance Quality System as amended from time to time, which is incorporated
    herein and made a part hereof by this reference.

A10.2    Supplemental Quality Requirements

A10.2.1  Use of Boeing Digital Datasets as Authority for Design and/or
         Inspection

When a supplier receives or uses Boeing digital data as authority for design
and/or inspection, then the supplier must comply to the requirements of D6-
51991, Quality Assurance Standards Reflecting Digital Product Definition for
Boeing Suppliers Using CAD/CAM/CAI Data, or contractual requirements.

A10.2.2  Seller's Inspection Options

The supplier shall perform either 100% inspection or acceptance sampling for
receiving inspection.  The supplier shall perform 100% inspection, acceptance
sampling or statistical process control for in-process inspection or final
inspection for each characteristic of a product.

A supplier that performs acceptance sampling shall have a Boeing-approved
acceptance sampling plan.  The plan shall meet the requirements of Boeing
document D1-8007, Approval Guide for Supplier statistical Sampling Plans.

When statistical process control is used as an option for either in-process or
final inspection, the supplier must satisfy the requirements of D6-82479,
Addendum 1.

In all cases, inspection requirements identified by engineering drawing or
specification take precedence over the inspection options described here and in
D6-82479, Addendum 1.  Boeing reserves the right to require 100% inspection for
selected characteristics.
