contained in this Agreement, any Airframe Services Order or any other
communications between Tramco and Customer, delivery dates or turn-times quoted

and terms as provided in this Agreement and the applicable Airframe Services

          6.2.  Time and Method of Payments.
                --------------------------- 

                 6.2.1.  Invoicing.  Upon completion of Airframe Services with 
                         ---------  
respect to an Aircraft, Tramco will prepare and submit to Customer an invoice or
invoices with respect to such Aircraft listing charges for the Airframe Services
and related parts and materials (the "Invoices"). Prior to redelivery of any
Aircraft to Customer, Customer shall pay to Tramco an amount equal to eighty
percent (80%) of the Estimated Labor Hours, eighty percent (80%) of the
estimated additional labor charges with respect to Airframe Services on such
Aircraft performed by Tramco on a Time and Materials basis, and one hundred
percent (100%) of the estimated charges for materials and third party services
on such Aircraft pursuant to Section 5.2. All such estimates shall not be
construed as a fixed determination of Invoice amounts, and as soon as
practicable following Aircraft redelivery Tramco will submit supplemental or
additional Invoices to reflect actual labor, material and other charges payable
by Customer pursuant to this Agreement. Additional amounts owing by Customer
pursuant to such additional Invoices shall be due and payable in United States
Dollars 30 days from the Invoice date. All Customer payments shall be made by
check or wire transfer to a Tramco account designated by Tramco in writing to
Customer. Any payments made by check shall be sent via overnight air courier
services (e.g. FedEx, UPS) to the Tramco address designated from time to time by
Tramco in writing. Notwithstanding the foregoing and in addition to any other
remedy to which Tramco may be entitled, Tramco may in its sole discretion demand
complete payment for 100% of all labor charges for Airframe Services with
respect to any Aircraft prior to the departure of such Aircraft from 

                                      -5-
<PAGE>
 
Tramco Airframe. In the event Tramco elects to require such payment, Customer
will be notified not less than five (5) days prior to the scheduled departure of
such Aircraft.

                 6.2.2.  Right of Customer to Review Records.  On the written 
                         -----------------------------------   
request of Customer from time to time during the Term of this Agreement (but not
more frequently than once in any twelve month period) and in addition to the
rights set forth in Section 5.5.4 with respect to Designated Maintenance
Representatives, Customer shall be permitted during normal business hours to
review Tramco's records related exclusively to (a) the manner and quality of
performance of Airframe Services on the Aircraft by Tramco, and (b) the accuracy
of any fees or charges invoiced by Tramco to Customer with respect to Airframe
Services provided by Tramco. The right of Customer to review Tramco records
shall extend to any agent, consultant or advisor of Customer reasonably
acceptable to Tramco which agrees to execute a confidentiality agreement in form
and substance satisfactory to Tramco, and which agrees to abide by applicable
Tramco safety and security restrictions. Notwithstanding the foregoing, neither
Customer nor its agents, consultants or advisors shall have any right to review
any other books and records of Tramco, including without limitation any books
and records relating to Tramco's fees or charges to any other customer or
Tramco's general accounts or financial information.

                 6.2.3.  Disputed Amounts.  Any Invoice submitted by Tramco 
                         ----------------  
shall be final as to Customer unless Customer shall have notified Tramco in
writing (a "Notice of Disagreement") within ninety (90) days of the Invoice date
of a disagreement with respect to all or a portion of any Invoice. Such Notice
of Disagreement shall specify the dollar amount of the disagreement (the
"Disputed Amount") and identify in reasonable detail the basis of Customer's
good faith determination that the invoice amount is incorrect. Customer shall
pay when due all amounts other than Disputed Amounts. Following receipt by
Tramco of a Notice of Disagreement, Tramco and Customer shall use good faith
efforts to resolve such Disputed Amounts. If Tramco and Customer are unable to
satisfactorily resolve such Disputed Amounts within thirty (30) days of receipt
of the Notice of Disagreement, then the Disputed Amount shall be promptly
submitted (by either party) to an independent public accounting firm of national
reputation which shall not have provided professional services to either Tramco
or Customer during the three year period prior to the date of the Notice of
Disagreement (the "Accounting Firm"). Customer and Tramco agree that the
Seattle, Washington office of Price Waterhouse LLP shall serve as the Accounting
Firm, provided that if such firm is unable or unwilling to provide such service
in any instance (including by reason of disqualification under the terms of this
Agreement), then the Seattle, Washington office of Deloitte & Touche LLP shall
serve as the Accounting Firm. If both Price Waterhouse LLP and Deloitte & Touche
LLP are unable or unwilling to serve as the Accounting Firm, then Tramco and
Customer shall mutually agree on the Accounting Firm. The Accounting Firm shall
be instructed to review the Disputed Amounts and to notify Customer and Tramco
as soon as practicable, and in any event not later than sixty (60) days
following the date of submission of the Disputed Amount to the Accounting Firm,
of its determination of the correct amount of the invoice payable by Customer.
Customer and Tramco agree to make available to the Accounting Firm such
information, books and records relating to the Disputed Amounts as may be
reasonably determined by the Accounting Firm to be necessary to complete its
review. The determination of the Accounting Firm shall be final and binding and
Customer shall pay to Tramco within five (5) days following receipt of the
report of the Accounting Firm such amount as the Accounting Firm has determined
is properly payable. The fees and expenses of the Accounting Firm shall be
allocated ratably between the parties in 

                                      -6-
<PAGE>
 
proportion to the dollar amount of adjustment to the Tramco invoice determined
by the Accounting Firm to be appropriate compared to the dollar amount of the
Disputed Amount.

                 6.2.4.  Late Payment Charges.  If any Customer payment 
                         --------------------      
obligation hereunder is not paid when due, (i) Customer shall pay interest on
such amount calculated from the date such amount is due until the date of
payment in full at the lower of one and one-half percent per month or the
maximum rate allowable under applicable law, and (ii) Tramco shall have the
right upon notice to Customer to suspend performance of Airframe Services and to
terminate this Agreement. No forbearance or course of dealing shall affect these
rights of Tramco.

          6.3.  Customer as Responsible Party.  Customer represents that it has
                -----------------------------                                  
all necessary authority to authorize the Airframe Services on the Aircraft.
Notwithstanding any understandings or agreements that Customer may have from
time to time with third parties and without limiting Tramco's rights or remedies
upon Customer's default, Tramco shall look solely to Customer for payment of all
amounts owing under this Agreement and the performance of all obligations of
Customer under this Agreement.  Customer shall hold harmless and defend Tramco
from and against any claims or charges asserted by any third parties claiming an
interest in the Aircraft, or questioning the purchase of the Airframe Services
by Customer from Tramco.

     7.  Material Supply.
         --------------- 

          7.1.  Material Procurement.  Tramco will provide all Expendables and
                --------------------                                          
Consumables which are required to perform the Airframe Services.  Parts and
components (other than Expendables and Consumables) identified pursuant to
Section 3.2 of this Agreement as required to complete the Workscope or otherwise
necessary for the performance of any Airframe Services will be provided by
Customer or, upon mutual agreement, by Tramco at the charges specified in
Section 5.  Customer and Tramco agree to cooperate in order to facilitate timely
procurement of parts and components.  All parts and components to be furnished
by Customer in connection with the Airframe Services shall be provided at Tramco
Airframe no later than seven days prior to commencement of the Airframe Services
on the Aircraft for which such part or component is required.  In no event shall
Tramco be liable for any delayed or untimely performance hereunder as a result
of (i) failure by Customer to deliver to Tramco any parts or components (other
than Expendables and Consumables) in a timely manner, or (ii) failure by Tramco
to obtain any parts which Customer has requested Tramco to obtain on its behalf.

          7.2.  Customer Parts and Equipment.  Any parts and material delivered
                ----------------------------                                   
to Tramco Airframe by or on behalf of Customer in connection with the Airframe
Services shall be handled by Tramco through its normal incoming material
receiving inspection routine.  A Customer Designated Maintenance Representative
shall be notified by Tramco of the inspection findings, and shall direct Tramco
as to the disposition of inspected items.  Tramco will hold any parts and
material determined by Customer to be scrapped, returned to the vendor or
otherwise disposed of, including any parts or materials removed from Customer
Aircraft (collectively, "Excess Material") at Tramco's facilities for a maximum
period of thirty (30) days, after which time Customer shall be responsible for
the removal, shipping and disposition of such Excess Material.  With Tramco's
consent and agreement, Excess Material may remain at Tramco's facilities beyond
such thirty (30) day period upon Customer's payment to Tramco of storage fees in
an 

                                      -7-
<PAGE>
 
amount which in Tramco's judgment is sufficient to compensate Tramco for all
costs and expenses related to the storage of such Excess Material. Tramco shall
maintain any parts and materials supplied to Tramco by Customer for use in
connection with the Airframe Services (and any Excess Material for the period
specified above) in a physically separated area within the Tramco facilities,
with appropriate identification of such parts and materials as the property of
Customer.  Tramco acknowledges and agrees that title to such parts and materials
supplied by Customer (and any Excess Material) shall at all times remain with
Customer.  Risk of loss with respect to the Customer supplied parts and
materials and Excess Materials shall remain with Tramco while such items are
located in the Tramco facility, and shall transfer to Customer at the time
physical possession of such parts or materials are delivered to Customer, or
such parts or materials are physically placed on an Aircraft.

     8.  Taxes.  Tramco shall pay any federal, state or local taxes based upon
         -----                                                                
Tramco's income or profits in connection with payments received under this
Agreement, including any gross receipts or business and occupation taxes.
Customer shall be responsible for the amount of any Washington State sales or
use taxes that result from the delivery of the Airframe Services provided by
Tramco hereunder or the purchase, sale, lease, exchange, transfer, replenishment
or maintenance of parts and supplies and other personal property for use in

Agreement.

transfer by operation of law) without the prior written consent of the other
party.  Consent to such assignment in one instance shall not constitute consent
to any other assignment.  No assignment shall relieve the assignee from its
obligations under this Agreement.  Any assignment or attempted assignment in
violation of the terms of this Section 15.9 shall be void.  Notwithstanding the
provisions of this Section 15.9, Tramco may assign this Agreement to The
B.F.Goodrich Company, or to any direct or indirect subsidiary or other affiliate
of Tramco or The B.F.Goodrich Company without the consent of Customer.

          15.10  Separable Provisions.  If any provision of this Agreement shall

respect to particular circumstances, it nevertheless shall remain in full force
and effect in all other circumstances.

          15.11  Mandatory Disclosure; Securities Laws Compliance.  (a) Customer
agrees that without the prior written consent of Tramco, Customer will not
disclose or provide copies of this Agreement or any Airframe Services Orders to
any third party or entity, including any court or other governmental agency or
body. In the event that Customer receives notification of a legal requirement to
disclose, or becomes legally compelled to disclose, a copy of or the terms of
this Agreement or any Airframe Services Orders or any proprietary information
subject to the provisions of Section 9 of this Agreement (collectively, the
"Information"), whether by deposition, interrogatory, request for documents by a
court or any governmental agency or body, subpoena, or other process or
requirement, whether legal, administrative or otherwise, Customer will provide
Tramco with prompt advance written notice (which shall not be less than five
business days in advance of the time for any such mandatory disclosure) so that
Tramco may seek a protective order, confidential treatment, waiver or other
appropriate protective relief with respect to all or part of such request or
requirement, or waive compliance with the provisions of this Agreement with
respect to all or part of such request or requirement. In the event that such
protective order, confidential treatment, waiver or other remedy is not obtained
prior to the deadline for complying with such request or requirement, and upon
advice of counsel Customer reasonably believes that it is legally compelled to
disclose Information, then Customer may disclose only that portion of the
Information which it is advised in writing by counsel that it is legally
compelled to disclose. Customer will use its best efforts to assist Tramco and
in no event will oppose any action by

                                      -13-
<PAGE>
 
Tramco to obtain appropriate confidential treatment or protective relief as
contemplated by this Section 15.11

                 (b)  Tramco acknowledges and agrees that Customer may be
required by applicable securities laws to issue a press release and to file this
Agreement with the Securities and Exchange Commission ("SEC"). Customer agrees
that it will provide Tramco with an advance copy of any press release and that
release of such press release or other public communication concerning the
arrangements contemplated hereby will be subject to the reasonable advance
consent of Tramco and will not, in any event disclose any specific pricing,
labor rates or other detailed business terms in such press release. Customer
acknowledges that the public disclosure of the commercial terms of this
Agreement is likely to cause substantial competitive harm to Tramco. Therefore,
Customer agrees to cooperate with Tramco to use all reasonable efforts to obtain
confidential treatment by the SEC of any portions of this Agreement and any
Airframe Services Orders which may be commercially sensitive.

          15.12  Counterparts.  This Agreement may be executed simultaneously in
                 -------------                                                  
two or more counterparts, including signature by facsimile, each of which shall
be deemed an original, but all of which together shall constitute one and the
same instrument.

          15.13  Interpretation.  This Agreement shall be governed by and
                 ---------------                                         
construed in accordance with the laws of the State of Washington, without
reference to any conflict of laws principles.  The language of this Agreement is
and will be deemed to be the language chosen by the parties jointly to express
their mutual understanding.  No rule of construction based on which party
drafted the agreement or certain of its provisions will be applied against
either party.

          15.14  Authorization.  Each of the parties hereby represents and
                 -------------                                            
warrants to the other that the execution, delivery and performance of this
Agreement and the transactions contemplated hereby have been duly authorized by
all necessary corporate action, and this Agreement, when duly authorized,
executed and delivered by the other party, will be a valid and binding
obligation of each party, respectively.
