                         NORTHWEST AIRLINES CORPORATION

- -------------------------------------------------------------------------------
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------

1.   The condensed consolidated financial statements of Northwest Airlines
     Corporation ("NWAC" or the "Company") included herein have been prepared
     pursuant to the rules and regulations of the Securities and Exchange
     Commission ("SEC").  Certain information and footnote disclosures normally
     included in annual financial statements prepared in accordance with
     generally accepted accounting principles have been condensed or omitted as
     permitted by such rules and regulations. These financial statements and
     related notes should be read in conjunction with the financial statements
     and notes thereto included in the Company's audited consolidated financial
     statements for the year ended December 31, 1996 contained in the Company's
     Annual Report on Form 10-K for 1996 (the "Annual Report").

     In the opinion of management, the interim financial statements reflect
     adjustments, consisting of normal recurring accruals, which are necessary
     to present fairly the Company's financial position, results of operations
     and cash flows for the periods indicated.

2.   The Company's accounting and reporting policies are summarized in Note A of
     the Notes to Consolidated Financial Statements in the Annual Report.

3.   The income tax expense is based on estimated annual effective tax rates
     which differ from the federal statutory rate of 35% primarily due to state
     income taxes and certain nondeductible expenses.

4.   At September 30, 1997, the Company had no borrowings outstanding under its
     revolving credit facility.  In addition, the Company has the ability under
     another facility to borrow up to $240 million using existing aircraft as
     collateral.  The $489.3 million available to be borrowed under the
     revolving credit facility along with the $240 million facility and the
     $1.22 billion of cash, cash equivalents and unrestricted short-term
     investments provided the Company with $1.95 billion of available liquidity
     at September 30, 1997.  Scheduled maturities of long-term debt subsequent
     to September 30, 1997 are $14.9 million in 1997, $159.5 million in 1998,
     $182.3 million in 1999, $96.0 million in 2000 and $125.9 million in 2001.

5.   The Company's aircraft orders as of September 30, 1997, include commitments
     to acquire 20 Airbus A320 aircraft, 50 Airbus A319 aircraft, 25 Boeing 757-
     200 aircraft, 16 Airbus A330 aircraft and four Boeing 747-400 aircraft.
     Committed expenditures for these aircraft and related equipment, including
     estimated amounts for contractual price escalations and predelivery
     deposits, will be approximately $18 million in 1997, $518 million in 1998,
     $828 million in 1999, $318 million in 2000, $430 million in 2001 and $879
     million in 2002.

     In October 1997, the Company exercised an option to purchase 24 additional
     Avro Regional Jet aircraft.  The Company now has on order 30 aircraft with
     two scheduled for delivery in 1997, ten each in 1998 and 1999 and eight in
     2000.  Committed expenditures for these aircraft, including contractual
     price escalations, are approximately $700 million. The Company will 
     lease six of the 30 aircraft to Mesaba Aviation, Inc. ("Mesaba") (in 
     addition to the six currently leased to Mesaba) under its Regional Jet 
     Services Agreement. The Company intends to lease the remaining 24 aircraft
     to one or more regional commuter airline partners.

6.   The Company manages a portion of the price risk of fuel costs utilizing
     both regulated exchange traded futures contracts and fuel swap agreements.
     The changes in market value of such agreements have a high correlation to
     the price changes of the fuel being hedged.  Gains or losses on open and
     closed hedge contracts are deferred and included in the condensed
     consolidated balance sheets as accounts payable and other liabilities or
     prepaid expenses, respectively, until the related fuel inventory is
     expensed, at which time both the fuel cost and gain or loss on the hedge
     instrument are accounted for as fuel expense.

7.   As discussed under "Management's Discussion and Analysis of Financial
     Condition and Results of Operations - Other Information," on September 29,
     1997, the Company entered into an agreement to repurchase for $1.12 billion
     over four years the NWAC common stock held by KLM Royal Dutch Airlines.  On
     that date, 6.8 million

                                        6

<PAGE>

     shares were repurchased along with all of the Company's Series A and B
     Preferred Stock held by KLM and other holders.  The remaining 18.2 million
     shares of common stock to be repurchased were reclassified to redeemable
     common stock from common stockholders' equity (deficit), as required for
     such stock transactions.  However, earnings per share calculations will
     continue to include the 18.2 million shares until actually repurchased.

8.   Currently, earnings per share ("EPS") calculations are performed pursuant
     to Accounting Principles Board Opinion No. 15.  NWAC will be required to
     present EPS data in accordance with Statement of Financial Accounting
     Standards No. 128 "Earnings per Share" commencing with the fourth quarter
     of 1997.  While early adoption of Statement No. 128 is not permitted, the
     following pro forma supplemental data is presented:

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

Substantially all of the Company's results of operations are attributable to
Northwest Airlines, Inc. ("Northwest") and the following discussion pertains
primarily to Northwest.  The Company acquired Express Airlines I, Inc.
("Express") on April 1, 1997 and the operating results of Express are included
in the consolidated financial statements commencing on that date.  See also
"Other Information - EXPRESS AIRLINES."  The Company's results of operations for
interim periods are not necessarily indicative of such results for an entire
year due to seasonal factors as well as competitive and general economic
conditions.

For the quarter ended September 30, 1997, the Company reported net income of
$290.3 million and operating income of $503.8 million.  Primary earnings per
common share were $2.75 ($2.51 fully diluted), an increase of $.33 ($.31 fully
diluted) excluding the effect of the July 1996 acquisition of a portion of the
Company's preferred stock which increased net income applicable to common
stockholders $74.5 million ($.73 primary and $.66 fully diluted).

Information with respect to the Company's operating statistics follows (1):

RESULTS OF OPERATIONS--THREE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996

Operating income increased $34.4 million to $503.8 million.  This increase was
primarily due to an increase in operating revenues of $66.2 million, a decrease
in aircraft fuel of $25.8 million and the conclusion of stock-based employee
compensation offset by increased salaries, wages and benefits of $95.4 million.

OPERATING REVENUES.  Operating revenues were $2.80 billion, an improvement of
$66.2 million (2.4%).  Consolidated system passenger revenues (which represented
87.4% of total operating revenues) were basically unchanged.  A 2.5% increase in
Northwest's scheduled service ASMs and the $36.2 million 1997 revenues of
Express were offset by a 2.8% decrease in Northwest's passenger revenue per
scheduled ASM ("RASM").  The decrease in RASM was due to a 3.9% decrease in
system yield.


                                        8

<PAGE>

Northwest's domestic passenger revenue increased $18.0 million (1.2%) to 
$1.53 billion due primarily to a 1.2% increase in scheduled service ASMs.  
Domestic RASM was unchanged because passenger load factor increased by 2.9% 
(2.1 pts.) and yield decreased by 2.9% due to the reinstatement of 
ticket taxes.  See also "Other Information - U.S. TRANSPORTATION TAX."  
Pacific passenger revenue decreased by $16.6 million (2.4%) to $670.6 million 
due to an 8.8% decrease in Pacific RASM which was offset by a 7.0% increase 
in scheduled service ASMs related to the initiation of Minneapolis/St. 
Paul-Osaka service and additional trans-Pacific frequencies, mainly 
Minneapolis/St. Paul-Tokyo.  The decrease in Pacific RASM was due to a 7.1% 
decrease in yield and a 1.9% (1.6 pts.) decrease in passenger load factor.  
Most of the Pacific yield decrease was attributable to a weaker Japanese yen. 
The average yen per U.S. dollar exchange rate for the three months ended 
September 30, 1997 and 1996 was 118 and 109, respectively, a weakening of the 
yen of 8.3%.  Atlantic passenger revenue decreased $9.2 million (4.2%) to 
$207.9 million due to a 3.7% decrease in scheduled service ASMs and a 0.6% 
decrease in RASM which was yield related.

Other revenues were $151.8 million, an improvement of $24.9 million (19.6%).
The improvement was largely due to increased revenue from KLM joint venture
alliance settlements and MLT Inc.

OPERATING EXPENSES.  Consolidated operating expenses increased $31.8 million
(1.4%).  While operating capacity increased 2.5% to 25.8 billion total service
ASMs, operating expense per total service ASM decreased 3.3%.  Salaries, wages
and benefits increased $95.4 million (14.4%) due to an increase in average full-
time equivalent employees of 2.6% and the end of the Wage Savings Period
discussed under "Other Information - LABOR AGREEMENTS."  The increase in average
full-time equivalent employees was attributable to increased flying of 2.5% and
increased traffic of 2.6%.  Aircraft fuel and related taxes decreased $25.8
million (7.0%) due to a 10.7% decrease in average fuel cost per gallon.

OTHER INCOME AND EXPENSE.  Interest expense-net decreased $7.2 million (10.9%)
primarily due to the retirement of debt prior to scheduled maturity and lower
interest rates on debt.  The foreign currency gain for the three months ended
September 30, 1997 was attributable to gains related to Japanese yen forward
exchange and collar option contracts and balance sheet remeasurement of foreign
currency-denominated assets and liabilities.

RESULTS OF OPERATIONS--NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996

Operating income decreased $48.6 million (5.0%) to $929.9 million.  The
favorable impacts of a $133.0 million increase in passenger revenues and the
conclusion of stock-based employee compensation were more than offset by
increases in salaries, wages and benefits of $305.8 million, aircraft
maintenance of $75.6 million and aircraft fuel of $48.7 million.

OPERATING REVENUES.  Consolidated operating revenues were $7.73 billion, an
improvement of $194.1 million (2.6%).  System passenger revenues (which
represented 86.9% of total operating revenues) increased $133.0 million (2.0%).
The increase was attributable to a 3.2% increase in Northwest's scheduled
service ASMs and the $73.9 million 1997 revenues of Express which were somewhat
offset by a 2.2% decrease in Northwest's RASM.  The decrease in RASM was
attributable to a 3.3% decrease in system yield which was partially offset by a
1.2% (0.9 pts.) increase in passenger load factor.

Northwest's domestic passenger revenue increased $118.3 million (2.7%) to 
$4.45 billion.  A 2.4% increase in scheduled service ASMs and a .4% increase 
in RASM resulted in the improved performance.  The increase in scheduled 
service ASMs resulted primarily from the addition of DC9-30, DC10-30 and 
Boeing 757 aircraft since the third quarter of 1996 which has allowed the 
Company to increase frequencies to 27 cities and enter five new markets.  The 
increase in RASM was due to a 2.1% (1.5 pts.) increase in passenger load 
factor offset by a 1.8% decrease in yield.  See also "Other Information - 
U.S. TRANSPORTATION TAX." Pacific passenger revenue decreased by $46.8 
million (2.7%) to $1.70 billion due to an 8.5% decrease in Pacific RASM which 
was somewhat offset by a 6.4% increase in scheduled service ASMs related to 
initiation of Minneapolis/St. Paul-Osaka service and additional trans-Pacific 
frequencies, mainly Minneapolis/St. Paul-Tokyo.  The decrease in Pacific RASM 
was primarily due to a 7.8% decrease in yield which was largely attributable 
to a weaker Japanese yen.  The average yen per U.S. dollar exchange rate for 
the nine months ended September 30, 1997 and 1996 was 120 and 107, 
respectively, a weakening of the yen of 12.1%.  Atlantic passenger revenue 
decreased $11.2 million (2.2%) to $494.0 million primarily due to a 2.3% 
decrease in scheduled service ASMs.  RASM was basically unchanged.

OPERATING EXPENSES.  Consolidated operating expenses increased $242.7 million
(3.7%).  While operating capacity increased 3.3% to 73.2 billion total service
ASMs, operating expense per total service ASM decreased .7%.  Salaries, wages
and benefits increased $305.8 million (15.7%) due to an increase in average
full-time equivalent employees of 3.3% and the end of the Wage Savings Period
discussed under "Other Information - LABOR AGREEMENTS."  The increase in average
full-time equivalent employees was attributable to increased flying of 3.3%.
Aircraft fuel and taxes increased $48.7 million (4.8%).  A 2.0% increase in
average fuel cost per gallon caused $19.5 million of the increase with the
balance attributable to increased flying.  Aircraft maintenance materials and
repairs increased $75.6 million (19.3%) due primarily to increased flying, an
increased number of engine and airframe overhauls and mandated fleet campaigns.

OTHER INCOME AND EXPENSE.  Interest expense-net decreased $25.0 million (12.5%)
primarily due to the retirement of debt prior to scheduled maturity and lower
interest rates on debt.  The foreign currency loss for the nine months ended
September 30, 1997 was attributable to balance sheet remeasurement of foreign
currency-denominated assets and liabilities and charges related to Japanese yen
forward exchange and collar option contracts. The foreign currency gain for the
nine months ended September 30, 1996 was primarily attributable to balance sheet
remeasurement of foreign currency-denominated assets and liabilities.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 1997, the Company had cash and cash equivalents of $1.07
billion, unrestricted short-term investments of $149.4 million, borrowing
capacity of $489.3 million under its revolving credit facility and the ability
under another facility to borrow up to $240 million using existing aircraft as
collateral, providing total available liquidity of $1.95  billion.  Net cash
provided by operating activities for the nine months ended September 30, 1997
was $1.48 billion, a $271.9 million increase compared with the nine months ended
September 30, 1996 largely due to an increase in the sale of frequent flyer
miles to WorldPerks partners of $407.5 million.  Investing activities in 1997
consisted primarily of costs to commission aircraft before entering revenue
service, aircraft deposits, DC9-50 interior refurbishment, the purchase of six
RJ85 aircraft, engine hushkitting, ground equipment purchases and the
acquisition of Express.  Investing activities in 1996 pertained primarily to the
acquisition of 22 aircraft, the purchase off lease of 21 aircraft and the
refurbishment of DC-9 aircraft.  Financing activities for the nine months ended
September 30, 1997, in addition to the repurchase of the Company's common and
preferred stock, included the issuance of  $150 million of 8.375% notes due 2004
and $100 million of 8.70% notes due 2007, the sale and leaseback of six RJ85
aircraft and the payment of debt and capital lease obligations.  Financing
activities in 1996 pertain primarily to the sale and leaseback of seven of the
thirteen 757 aircraft and the payment of debt and capital lease obligations.

As discussed under "Other Information - KLM AGREEMENTS," on September 29, 1997,
the Company entered into an agreement to repurchase for $1.12 billion over four
years the NWAC common stock held by KLM Royal Dutch Airlines ("KLM") and, on
that date, 6.8 million shares were repurchased for $273.1 million.
Concurrently, all of the Company's Series A and B Preferred Stock held by KLM
and other holders was repurchased for $251.3 million.  The 1997 repurchases were
funded using existing cash resources.  The funding of subsequent tranches will
be determined based on conditions at the time.

OTHER INFORMATION

LABOR AGREEMENTS.  The Company's labor agreements provided for wage and other
cost reductions which aggregated $897 million over 36 to 39 month periods
(depending on the labor group) (the "Wage Savings Period").  The Wage Savings
Period ended on July 31, 1996 for flight attendants, September 30, 1996 for
mechanics, ground personnel and management and October 30, 1996 for pilots.  The
Company's agreements with the employee unions provided that wage scales at the
end of the Wage Savings Period snapback to August 1, 1993 levels and snap-up
pursuant to formulae based in part on wage rates and wage rate increases at
other large U.S. airlines.  Consequently, at the end of the Wage Savings Period,
salaries and wages increased by approximately $340 million on an annualized
basis including $50 million for snap-ups.  Management's Discussion and Analysis
of Financial Condition and Results of Operations and Note B of the Notes to
Consolidated Financial Statements in the Annual Report contain additional
discussion of the labor cost savings agreements, stock issued to employees and
the related accounting treatment.


                                       10

<PAGE>

FOREIGN CURRENCY. The Company's annual yen-denominated revenues exceed its yen-
denominated expenses by approximately 70 billion yen and its yen-denominated
liabilities exceed its yen-denominated assets.  In general, as the Japanese yen
strengthens (weakens), the Company's operating income is favorably (unfavorably)
impacted and a nonoperating foreign currency loss (gain) is recognized due to
the remeasurement of net yen-denominated liabilities.  In recent periods, the
yen has weakened as the yen to U.S. dollar exchange rate has changed from 111
yen to $1 at September 30, 1996 to 116 yen to $1 at December 31, 1996 and 120
yen to $1 at September 30, 1997.

USE OF FINANCIAL INSTRUMENTS.  In order to mitigate its exposure to foreign
exchange rate fluctuations, from time to time the Company enters into forward
exchange and collar option contracts to hedge its anticipated yen-denominated
net cash flows.  At September 30, 1997, the Company had $122.8 million (14.8
billion yen) in forward exchange and collar option contracts outstanding to
hedge approximately 90% of its remaining 1997 anticipated yen-denominated net
cash flows.  In the ordinary course of business, the Company manages the price
risk of fuel costs utilizing both regulated exchange traded futures contracts
and fuel swap agreements.  Gains or losses on hedge contracts are deferred until
the related fuel inventory is expensed.  As of September 30, 1997, the Company
had hedged approximately 73% of its remaining 1997 fuel requirements.

U.S. TRANSPORTATION TAX.  The United States 10% passenger ticket tax applicable
to domestic travel, the 6.25% domestic cargo waybill tax and the $6 per
passenger international departure tax expired on December 31, 1995.
Consequently, the Company ceased collecting these taxes on January 1, 1996.
These taxes were reinstated for tickets sold subsequent to August 27, 1996 for
travel through December 31, 1996.  These taxes lapsed again on December 31, 1996
and were reinstated for tickets sold from March 7, 1997 to September 30, 1997.
The Company estimates that the reinstatement of the transportation taxes had a
$95 million and $153 million adverse impact on passenger revenues for the three
and nine months ended September 30, 1997, respectively.

Congress enacted legislation which revised transportation taxes and 
instituted new taxes for tickets for travel on October 1, 1997 to December 
31, 2007.  The legislation included a reduction in the domestic passenger 
ticket tax to 7.5% over three years (the rate decreased to 9% on October 1, 
1997) with certain rural airports subject to a 7.5% tax throughout the life 
of the bill.  The $6 international departure tax increased to $12 and a new 
$12 international arrival tax was imposed (both began for tickets sold on or 
after August 13, 1997 for travel commencing on or after October 1, 1997).  
The departure tax on travel between the U.S. 48 states and Alaska or Hawaii 
remained at $6.  A new segment fee applicable to domestic travel began at $1 
for the period from October 1, 1997 to September 30, 1998 and will gradually 
increase to $3 for the calendar year 2002. Rural airports are exempt from 
this segment fee, but travel between the U.S. 48 states and Alaska or Hawaii 
is subject to this new tax.  Both the international departure and arrival 
taxes and the segment fee will be indexed each year to the consumer price 
index.  In addition, a 7.5% tax on the sale of frequent flyer miles was 
included in the legislation.  The impact of the changes is expected to 
increase annualized U.S. transportation taxes collected by Northwest from 
current levels by approximately $50 million resulting in an undetermined 
dilution of future passenger revenue.

EXPRESS AIRLINES.  On April 1, 1997, NWA Inc., a wholly owned subsidiary of the
Company, purchased all of the outstanding stock of Express Airlines I, Inc. and
an affiliate.  Express is a regional carrier that provides passenger traffic to
Northwest at Memphis.

AIRBUS A319 ORDER.  On September 19, 1997, Northwest entered into an 
agreement with AVSA, S.A.R.L. for the purchase by Northwest of 50 firm Airbus 
A319 aircraft and up to 100 option Airbus A319/A320 aircraft. The 50 firm 
aircraft are scheduled to be delivered ten per year beginning in 1999.

KLM AGREEMENTS.  On September 29, 1997, the Company and KLM expanded their 
alliance by entering into an enhanced commercial and operational alliance 
providing for a minimum term of 13 years.  The Company and KLM also entered 
into agreements providing for the acquisition by NWAC of all its common and 
preferred stock held by KLM, including an additional 3.29 million shares of 
common stock that KLM acquired from other stockholders.  On September 29, 
1997, 6.8 million shares were repurchased along with all of the Company's 
Series A and B Preferred Stock held by KLM and other investors for $524.4 
million.  The remaining 18.2 million shares of common stock to be repurchased 
were reclassified to redeemable common stock from common stockholders' equity 
(deficit), as required for such stock transactions.  However, earnings per 
share calculations will continue to include the 18.2 million shares until 
actually repurchased.

The Company will repurchase the remaining common shares over three years as
follows:  4.9 million in 1998, 3.22 million in 1999 and 10.05 million in 2000.
The purchase price for the second, third and fourth tranches is $42.87, $45.75
and $48.83 per common share, respectively, subject to adjustment for certain
change in control or equity issuance transactions.  Concurrently with the
purchase of the first tranche, all of KLM's existing governance rights under
various stockholder and other agreements were cancelled, the Company and KLM
entered into an agreement containing standstill obligations and KLM withdrew its
pending legal actions.  As a result of these transactions, KLM's common stock
voting position in the Company decreased to 17 percent after the sale of the
first tranche and then will decrease to 13 percent in 1998, 10 percent in 1999
and zero percent in 2000 with the sale of the final tranche.  The closing of the
third and fourth tranches is subject to the alliance maintaining certain
antitrust immunity and if either tranche does not close, KLM's remaining common
shares will be converted to non-voting Class B Common Stock and Northwest will
have the right to terminate the alliance.  In addition, the Company has the
right to accelerate the repurchase of the stock from KLM subject to certain
conditions and limitations.

Under the alliance agreement, the two airlines will expand their current areas
of cooperation to include services between Europe and Canada, India and Mexico.
In addition, the two companies plan to increase the level of cooperation between
their respective cargo divisions and will explore extending their alliance to
include additional partners and to further develop strategies for joint
marketing and product development.

2 -  SALE AND PURCHASE

2.1  GENERAL

     AVSA will cause to be manufactured and will sell and deliver, and Northwest
     will buy and take delivery of, the Aircraft subject to the terms and
     conditions contained in this Agreement.

2.2  SPECIFICATION DOCUMENTS

     The Aircraft will be manufactured in accordance with the A319-100 Standard
     Specification, Document No. J.000.01000, Issue 3, dated March 29, 1995,
     including Temporary Revision 1, dated August 25, 1995.  Such Standard
     Specification, a copy of which is annexed hereto as Exhibit A to this
     Agreement, as amended by the change orders set forth in Exhibit B hereto,
     is hereinafter referred to as the "Specification."  The Specification may
     be further modified from time to time pursuant to the provisions of Clause
     3 below.

2.3  CERTIFICATION

     Prior to the delivery of the first Aircraft, AVSA will obtain or cause to
     be obtained a US FAA Type Certificate (transport category) for the Aircraft
     pursuant to Part 21 and in compliance with the applicable provisions of
     Part 25 of the US Federal Aviation Regulations.

     Each Aircraft will be delivered to Northwest with the Certificate of 
     Airworthiness for Export issued by the LBA and in a condition enabling 
     Northwest (or a person eligible to obtain such certificate under then 
     applicable law) to obtain at the time of delivery a Standard 
     Airworthiness Certificate issued pursuant to Part 21 of the US Federal 
     Aviation Regulations permitting Northwest to operate the Aircraft under 
     Part 121 of the US Federal Aviation Regulations.  AVSA will have no 
     obligation, whether before, at or after delivery of any Aircraft, to 
     make any alterations to such Aircraft to enable such Aircraft to meet 
     FAA requirements for non-standard operation on Northwest's routes.  
     Except as set forth in this Subclause 2.3, AVSA will not be required to 
     obtain any other certificate or approval with respect to the Aircraft.

2.4  AVSA will deliver each Aircraft with provisions suitable for that equipment
     required to be incorporated on such Aircraft to meet those additional
     requirements of the US Federal Aviation Regulations which (i) are generally
     applicable with respect to transport category aircraft to be used in United
     States certificated air carriage and (ii) are required to be complied with
     on or before the date of delivery of such Aircraft, provided that any
     required amendment to the Specification resulting from such additional
     requirements will be set forth in an SCN which will be effected as provided
     in Clause 3 hereof.  Northwest will cooperate with AVSA in complying with
     the foregoing requirements.

3 -  CHANGES

3.1  SPECIFICATION CHANGE NOTICES

     The Specification may be amended from time to time by a Specification
     Change Notice (each such Specification Change Notice being herein called an
     "SCN" and being in the form of Exhibit C hereto). Each SCN will set forth
     in detail the particular changes to be made in the Specification, any
     materials to be deleted from the Aircraft by AVSA in connection with such
     SCN, and the effect, if any, of such changes on design, performance,
     weight, balance, time of delivery, Buyer Furnished Equipment and price of
     each Aircraft affected thereby and interchangeability or replaceability of
     parts.  SCNs will not be binding on either party until signed by persons
     duly authorized in writing by Northwest and AVSA, but upon being so signed
     will constitute amendments to this Agreement.

3.2  DEVELOPMENT CHANGES

     The Specification may also be revised by AVSA without an SCN or Northwest's
     consent to incorporate Manufacturer-decided changes that are deemed
     necessary or useful to correct defects, improve the Aircraft or its process
     of manufacture, prevent delay, or ensure compliance with this Agreement and
     that do not increase the price or adversely affect the delivery, overall
     dimensions, guaranteed weight, maintenance requirements or performance of
     the Aircraft or adversely change the interchangeability or replaceability
     requirements of the Specification (hereinafter called "Development
     Changes").  AVSA will notify Northwest of all Development Changes prior to
     incorporation therein.

3.3  REQUESTS AND APPROVALS

3.3.1     In the event that Northwest requests a change to the Specification,
          AVSA will issue a Request for Change (RFC) and carry out a feasibility
          study of such change.  If AVSA determines that such RFC is feasible to
          incorporate, AVSA will produce an SCN and submit such SCN to Northwest
          for Northwest's approval.  If such SCN is rejected by Northwest, such
          RFC and proposed SCN will be canceled without charge to Northwest.  

3.3.2     In the event that Northwest requests AVSA in writing to incorporate a
          proposed change (excluding Development Changes) in an Aircraft and
          AVSA agrees to such request but the change is not subsequently made
          the subject of an SCN for any reason (other than AVSA's unreasonable
          refusal to sign the SCN or otherwise acting in bad faith), Northwest
          will pay AVSA the full cost of design and other work resulting from
          such request and incurred by AVSA, provided that in the event AVSA's
          reasonable estimate of the cost of developing such proposed change is
          higher than US$ {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY
          WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL


                                      7

          TREATMENT}, AVSA shall have notified Northwest in writing
          within {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} Working Days after AVSA's receipt of
          Northwest's request of such cost estimate and secured Northwest's
          agreement prior to incurring any such costs.  

          In the event that Northwest requests AVSA in writing to proceed 
          with a proposed change before any requisite approval of the LBA and 
          FAA has been obtained and such LBA or FAA approval is not 
          subsequently obtained, any SCN executed in connection with such 
          proposed change will be {CONFIDENTIAL MATERIAL OMITTED AND FILED 
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO 
          A REQUEST FOR CONFIDENTIAL TREATMENT}.

3.4  SPECIFICATION CHANGES BEFORE DELIVERY

     If, pursuant to the promulgation of any applicable law or regulation, any
     change in the Specification has to be made before delivery of any Aircraft
     to enable Northwest to obtain a Standard Airworthiness Certificate for such
     Aircraft referred to in Subclause 2.3, AVSA will make or cause to be made
     the required change or modification to the Aircraft.  For each such change,
     the parties will sign an SCN specifying the effect, if any, of such change
     on design, performance, weight, balance, time of delivery, and Buyer
     Furnished Equipment of each Aircraft affected thereby and
     interchangeability or replaceability of parts. If AVSA anticipates that the
     scheduled delivery of any Aircraft will be postponed by reason of such
     change, the delivery date of such Aircraft as provided in Subclause 9.1
     will be extended to the extent of such postponement.

     The effect on price of such a change will be borne {CONFIDENTIAL MATERIAL
     OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION
     PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT}.

3.5  SPECIFICATION CHANGES AFTER DELIVERY

     Subclause 3.4 will not require AVSA to make any changes or modifications to
     or to make any payments or take any other action with respect to any
     Aircraft delivered to Northwest prior to the time any law or regulation
     referred to in Subclause 3.4 becomes effective.  Any such changes or
     modifications made to an Aircraft after its delivery to Northwest will be
     at Northwest's expense.

               delivery of such Aircraft in accordance with Subclause 5.1 of 
               this Agreement; 

        (iii)  the Reference Price of the installed Propulsion Systems
               constituting a part of such Aircraft, as adjusted to the date of

               such Aircraft in accordance with Subclause 5.1 of this Agreement;
               and

          (v)  any other amount resulting from any other provisions of this 
               Agreement and/or any other written agreement between Northwest 
               and AVSA relating to the Aircraft and specifically making
               reference to the Final Contract Price of an Aircraft.

4.3  TAXES, DUTIES AND IMPOSTS

4.3.1     AVSA will bear and pay the amount of any and all taxes, duties,
          imposts or similar charges of any nature whatsoever {CONFIDENTIAL
          MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} that are
          (i) imposed upon Northwest, (ii) imposed upon AVSA with an obligation
          on Northwest to withhold or collect the amount thereof from AVSA or
          (iii) imposed upon Northwest with an obligation on AVSA to withhold or
          collect such amount from Northwest, and that are levied, assessed,
          charged or collected for or in connection with the fabrication,
          manufacture, modification, assembly, sale, delivery, use of or payment
          under this Agreement for any Aircraft, component, accessory, equipment
          or part delivered or furnished hereunder, provided such taxes, duties,
          imposts or similar charges have been levied, assessed, charged or
          collected under laws promulgated and enforceable in Germany
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT}.

4.3.2     Northwest will bear and pay the amount of any and all taxes, duties,
          imposts or similar charges of any nature whatsoever that are (i)
          imposed upon AVSA, (ii) imposed upon Northwest with an obligation on
          AVSA to collect the amount thereof for Northwest or (iii) imposed upon
          AVSA with an obligation for Northwest to withhold such amount 


                                       11
<PAGE>

          from AVSA, and that are levied, assessed, charged or collected for or
          in connection with the fabrication, manufacture, modification, 
          assembly, sale, delivery or use of or payment under this Agreement for
          any Aircraft, component, accessory, equipment or part delivered or
          furnished hereunder, provided such taxes, duties, imposts or similar
          charges have been levied, assessed, charged or collected under laws
          promulgated and enforceable in countries other than Germany
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT}. If Northwest is compelled by law to pay such
          taxes, duties, imposts or similar charges as a deduction or
          withholding , then Northwest will ensure that the sums received by
          AVSA under this Agreement  will be equal to the full amounts expressed
          to be due AVSA hereunder, without deduction or withholding on account
          of and free from any and all taxes, levies, imposts, duties or charges
          of whatever nature, and Northwest will pay such additional amounts as
          may be necessary so that the net amount received by AVSA after such
          deduction or withholding will equal the amounts that would have been
          received in the absence of such deduction or withholding.
 
4.3.3     AVSA will in its own name do all things necessary with respect to the
          export of the Aircraft from Germany and will pay any customs duties,
          taxes and fees required to be paid with respect to such export of the
          Aircraft which are imposed under laws promulgated and enforceable in
          Germany {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT}.

4.3.4     It is expressly understood and agreed that AVSA's undertaking in
          Subclause 4.3.1 will not apply to taxes, duties, imposts or similar
          charges of any nature whatsoever, relating to the use of or payment
          for any Aircraft (excluding income, franchise, and doing business
          taxes imposed on AVSA), component, accessory, equipment or part
          delivered or furnished under this Agreement in the United States of
          America.  

4.3.5     It is expressly understood and agreed that Northwest's undertaking in
          Subclause 4.3.2 will not apply to taxes imposed on AVSA that are based
          on or measured by gross or net income or receipts or that are based on
          or measured by AVSA's doing business, capital or net worth, or other
          taxes, however denominated, in the nature of such taxes.

       AVSA the Final Contract Price therefor, less the total amount of the 
       Predelivery Payments theretofore received by AVSA for such Aircraft 
       under Subclause 6.2 above.  AVSA's receipt of the full amount of such 
       payments will be a condition precedent to AVSA's obligation to deliver 
       such Aircraft.

6.4    PAYMENT OF OTHER AMOUNTS

6.4.1  Unless otherwise expressly provided for herein, any payments due
       hereunder or in respect of an Aircraft in addition to those referred
       to in Subclauses 6.2 and 6.3 above will be paid by Northwest
       concurrently with the delivery of the corresponding Aircraft or, if
       invoiced after delivery of such Aircraft, within {CONFIDENTIAL
       MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
       COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} after the
       invoice date.  AVSA and Northwest agree that with respect to payments
       to be made under this Subclause 6.4.1, and for the purposes of Clause
       21, Northwest will not be deemed to be in default unless such payment
       is not made within {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY
       WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
       CONFIDENTIAL TREATMENT} after invoice date. 

6.4.2  Notwithstanding any other rights AVSA may have at contract or at law,
       Northwest and AVSA hereby agree that should any amount under this
       Agreement  become due and payable by Northwest, and not be paid in
       full in immediately available funds on the date due (unless contested
       by Northwest in good faith), then AVSA will have the right to debit
       and apply, in whole or in part, the unused amount of any credit made
       available by AVSA to Northwest against such unpaid amount.  AVSA will
       promptly notify Northwest in writing after such debiting and
       application.

6.5  OVERDUE PAYMENTS

     If any payment due AVSA is not received by AVSA on the date or dates as
     agreed upon between Northwest and AVSA, AVSA will have the right to claim
     from Northwest,  and Northwest will promptly pay to AVSA, upon receipt of
     such claim,  interest (on the basis of a 365 day year) at a rate per annum
     equal to the sum of {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY
     WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
     CONFIDENTIAL TREATMENT} on the amount of such overdue payment, to be
     calculated from and including the due date of such payment to (but
     excluding) the date such payment is received by AVSA.  AVSA's right to
     receive such interest will be in addition to any other rights of AVSA
     hereunder or at law.

6.6  REFUND OF PREDELIVERY PAYMENTS

     Northwest will have no right to any refund of any deposit or Predelivery
     Payment received by AVSA, except as provided under Clauses 10, 11, and
     {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
     EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT}.

6.7  PROPRIETARY INTEREST

     Northwest will not, by virtue of anything contained in this Agreement
     (including, without limitation, any Predelivery Payments hereunder, or any
     designation or identification by AVSA of a particular Aircraft as an
     Aircraft to which any of the provisions of this Agreement refer), and
     notwithstanding any provision of law to the contrary, acquire any
     proprietary, insurable or other interest whatsoever in any Aircraft prior
     to delivery of and payment in full for such Aircraft as provided in this
     Agreement.

6.8  TENDER OF DELIVERY

     In addition to any other rights and remedies available to AVSA, AVSA will
     not be obligated to tender delivery of any Aircraft to Northwest and will
     have no further liability to Northwest with respect thereto, if Northwest
     fails to make any Predelivery Payment {CONFIDENTIAL MATERIAL OMITTED AND
     FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
     REQUEST FOR CONFIDENTIAL TREATMENT} or if AVSA has terminated this
     Agreement pursuant to Clause 21.

6.9  PAYMENT IN FULL

     Except as provided for herein, Northwest's obligation to make payments to
     AVSA hereunder will not be affected by and will be determined without
     regard to any set off, counterclaim, recoupment, defense or other right
     that Northwest may have against AVSA or any other person and all such
     payments will be made without deduction or withholding of any kind.

          Associated Contractors' or their respective subcontractors'
          engineering or other personnel by Northwest and its said
          representatives will be performed in such manner as not to delay or
          hinder the work to be carried out on the Aircraft or the proper
          performance of this Agreement.  In no event will Northwest or its
          representatives be permitted to inspect any aircraft other than the
          Aircraft. 

7.2       INDEMNITY

          SELLER'S INDEMNITY

          AVSA WILL INDEMNIFY AND HOLD HARMLESS NORTHWEST, ITS DIRECTORS,

     ITS REPRESENTATIVES, IN EITHER CASE WHEN ARISING OUT OF OR IN CONNECTION
     WITH ANY SUCH TESTS, CHECKOUTS, OR INSPECTIONS UNDER THIS CLAUSE 7.  THIS
     INDEMNITY OF AVSA WILL NOT APPLY FOR ANY SUCH LIABILITIES, DAMAGES, LOSSES,
     COSTS OR EXPENSES ARISING OUT OF OR CAUSED BY THE GROSS NEGLIGENCE OR 
     WILLFUL MISCONDUCT OF NORTHWEST'S SAID REPRESENTATIVES.

     NORTHWEST WILL INDEMNIFY AND HOLD HARMLESS AVSA, THE MANUFACTURER, EACH OF

     RESPECTIVE OFFICERS, AGENTS AND EMPLOYEES FROM AND AGAINST ALL LIABILITIES,

8 -  NORTHWEST'S ACCEPTANCE

8.1  ACCEPTANCE PROCEDURES

8.1.1     AVSA or any Affiliate thereof acting as AVSA's designee will give to
          Northwest not less than {CONFIDENTIAL MATERIAL OMITTED AND FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
          REQUEST FOR CONFIDENTIAL TREATMENT} days prior written notice of the
          proposed time when acceptance tests of an Aircraft will be conducted,
          and, in the event that Northwest elects to attend such tests,
          Northwest will comply with the reasonable requirements of AVSA with
          the intention of completing all tests within {CONFIDENTIAL MATERIAL
          OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} Working
          Days after commencement.  The tests will take place at Daimler-Benz's
          works in Hamburg, Germany (or at such other facilities of the
          Associated Contractors or any Affiliates thereof as AVSA may specify
          in its notice to Northwest pursuant to this Subclause 8.1.1) and will
          be carried out by the personnel of the Manufacturer (accompanied, if
          Northwest so wishes, by representatives of Northwest up to a total of
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} acting as observers, of whom not more than
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} will have access to the cockpit at any one
          time).  During flight tests, these representatives will comply with
          the instructions of the Manufacturer's representatives.  The
          Manufacturer will not normally be required in the course of such
          acceptance tests to fly any of the Aircraft for more than an aggregate
          of {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} hours.

8.1.2     AVSA will offer to Northwest a briefing prior to acceptance of each
          Aircraft and {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH
          THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} hour simulator session for {CONFIDENTIAL
          MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} pilots,
          prior to acceptance of the first Aircraft.  This briefing will provide
          specific information related to acceptance flights.

8.1.3     The acceptance tests must demonstrate the satisfactory functioning of
          the Aircraft at the time of delivery in accordance with the
          Specification (except for immaterial variances from the
          Specification).  In the event that Northwest, after having received
          proper notice in accordance with Subclause 8.1.1, does not attend the
          tests scheduled for an Aircraft or fails to so cooperate, AVSA may
          complete them in the absence of Northwest, whereupon 


                                       18
<PAGE>

          Northwest will be deemed to have accepted the tests, if such tests 
          demonstrate the satisfactory functioning of the Aircraft as aforesaid,
          and AVSA will furnish such data with respect to such tests as 
          Northwest may reasonably request.

8.1.4     If the acceptance tests for an Aircraft are not successfully completed
          or there is a defect, Northwest, within {CONFIDENTIAL MATERIAL OMITTED
          AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION
          PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} Working Days after
          such tests, will give notice to AVSA specifying such unsuccessful
          completion or defect.  Thereafter AVSA will, without hindrance from
          Northwest, carry out any necessary changes and, as soon as practicable
          thereafter, resubmit the Aircraft for new acceptance tests to
          demonstrate the elimination of the defect, such tests to be held and
          carried out in accordance with Subclause 8.1, provided, however,
          rather than accept a delay in delivery of any such Aircraft, Northwest
          and AVSA may agree to deliver such Aircraft with subsequent correction
          of the defect by Northwest {CONFIDENTIAL MATERIAL OMITTED AND FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
          REQUEST FOR CONFIDENTIAL TREATMENT}.

8.2  USE OF AIRCRAFT

     AVSA will be entitled to use any Aircraft prior to its delivery to
     Northwest:
     
      (i) without Northwest's prior consent, to the extent necessary to carry
          out the normal manufacturing process of the Aircraft (but in no event
          for more than {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH
          THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} flight hours in the case of each Aircraft), 

     (ii) without Northwest's prior consent, to obtain the certificates required
          under Clause 2 hereof {CONFIDENTIAL MATERIAL OMITTED AND FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
          REQUEST FOR CONFIDENTIAL TREATMENT} or

    (iii) with Northwest's prior consent (such consent not to be unreasonably
          withheld), for the purposes of demonstration flights to third parties
         (the "Demonstration Flights").

     Such use will not affect either AVSA's obligation to deliver any Aircraft
     hereunder or Northwest's obligation to accept delivery of any Aircraft
     hereunder.  Northwest will have the right, however, to obtain a credit from
     AVSA for {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
     SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
     TREATMENT} flight hours accumulated during Demonstration Flights. 
     {CONFIDENTIAL MATERIAL 


                                       19
<PAGE>

     OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION
     PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} Such credit will be equal
     to the product of (i) the number of flight hours accumulated {CONFIDENTIAL
     MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE 
     COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} for 
     Demonstration Flights and (ii) US$ {CONFIDENTIAL MATERIAL OMITTED AND FILED
     SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
     REQUEST FOR CONFIDENTIAL TREATMENT}.  Northwest will accept delivery of any
     Aircraft used in accordance with this Subclause 8.2 without  any reduction
     in price for depreciation, or wear and tear resulting from such use.

8.3   CERTIFICATE OF ACCEPTANCE

      When the Aircraft is "ready for delivery" as defined below in Subclause
      9.2, Northwest will forthwith give to AVSA a signed Certificate of
      Acceptance in the form attached as Exhibit F in respect of the relevant
      Aircraft.  Should Northwest fail to so deliver the said Certificate, then
      Northwest will be deemed to be in default as though it had without cause

10 -  EXCUSABLE DELAY

10.1  SCOPE

      Neither AVSA nor the Manufacturer will be responsible for or be deemed to 
      be in default on account of delays in delivery or failure to deliver or 
      otherwise in the performance of this Agreement or any part hereof (i) due 
      to causes reasonably beyond AVSA's, the Manufacturer's or any Associated 
      Contractor's control (unless such cause is beyond such control due to 
      AVSA's, the Manufacturer's or the Associated Contractor's fault or 
      negligence) or (ii) not occasioned by AVSA's, the Manufacturer's or any 
      Associated Contractor's fault or negligence ("Excusable Delay"), 
      including, but not limited to:  acts of God or the public enemy, natural 
      disasters, fires, floods, hail storms, explosions or earthquakes; 
      epidemics or quarantine restrictions; serious accidents; actual total or 
      constructive total loss; any law, decision, regulation, directive or 
      other act (whether or not having the force of law) of any government or 
      of the Council of the European Community or the Commission of the 
      European Community or of any national, Federal, State, municipal or other 
      governmental department, commission, board, bureau, agency, court or 
      instrumentality, domestic or foreign; governmental priorities, 
      regulations or orders affecting allocation of materials, facilities or a 
      completed Aircraft; war, civil war or warlike operations, terrorism, 
      insurrection or riots; failure of transportation; strikes or labor 
      troubles causing cessation, slow down or interruption of work; delay in 
      obtaining any airworthiness certification for a previously uncertificated 
      Aircraft part, component or computer software after due and timely 
      diligence to procure such certification; inability after due and timely 
      diligence to procure materials, accessories, equipment or parts; general 
      hindrance in transportation; or failure of a subcontractor or Vendor to 
      furnish materials, components, accessories, equipment or parts.
 
      It is expressly understood and agreed that each of (i) any delay caused 
      by Northwest's negligence or fault, and (ii) delay in delivery or 
      otherwise in the performance of this Agreement by AVSA due in whole or in 
      part to any delay in or failure of the delivery of, or any other event or 
      circumstance relating to, the Propulsion Systems or Buyer Furnished

      as practicable after becoming aware of any delay falling within the 
      provisions of this Subclause 10.1 (a) notify Northwest of such delay and 
      of the probable extent thereof and (b) subject to the following 
      provisions, as soon as practicable after the removal of the cause or

      REQUEST FOR CONFIDENTIAL TREATMENT}, the performance of those obligations

      or forego in the exercise of sound business judgement.

10.2  UNANTICIPATED DELAY

      In the event that the delivery of any Aircraft is delayed by reason of an 
      Excusable Delay for a period of more than {CONFIDENTIAL MATERIAL OMITTED 
      AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT 
      TO A REQUEST FOR CONFIDENTIAL TREATMENT} months after the end of the 
      calendar month in which delivery is otherwise required hereunder, 
      Northwest will be entitled to terminate this Agreement with respect only 
      to the Aircraft so affected upon written notice given to AVSA within 
      {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES 
      AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} 
      days after the expiration of such {CONFIDENTIAL MATERIAL OMITTED AND 
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO 
      A REQUEST FOR CONFIDENTIAL TREATMENT} month period.  In the event such 
      delay continues for an additional {CONFIDENTIAL MATERIAL OMITTED AND 
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO 
      A REQUEST FOR CONFIDENTIAL TREATMENT} month period after the expiration 
      of such {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE 
      SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL 
      TREATMENT} month period and Northwest has not theretofore terminated this 
      Agreement with respect to such Aircraft,  either party will have the 
      option to terminate this Agreement with respect to the Aircraft so 
      affected upon written notice given to the other within {CONFIDENTIAL 
      MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE 
      COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} days after 
      the end of such additional {CONFIDENTIAL MATERIAL OMITTED AND FILED 
      SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
      REQUEST FOR CONFIDENTIAL TREATMENT} month period. Such termination, as 
      aforesaid, will discharge all obligations and liabilities of the parties 
      hereunder with respect to such affected Aircraft, except that AVSA will 
      repay to Northwest all amounts required by {CONFIDENTIAL MATERIAL OMITTED 
      AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT 
      TO A REQUEST FOR CONFIDENTIAL TREATMENT} with respect to such affected 
      Aircraft, {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE 
      SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL 
      TREATMENT}.  Northwest will not be entitled to receive such repayment nor 
      to terminate this Agreement as to any Aircraft under this Clause 10 by 
      reason of an Excusable Delay if such delay is caused solely by 
      Northwest's negligence or Northwest's fault.
 
10.3  ANTICIPATED DELAY
 
      In respect of any Aircraft, AVSA may conclude, based on a reasonable and 
      good faith appraisal of the facts, that Excusable Delays will (i) cause 
      delay in delivery of such Aircraft for a period of more than {CONFIDENTIAL
      MATERIAL OMITTED AND 

                                      27
<PAGE>

     FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
     REQUEST FOR CONFIDENTIAL TREATMENT} months after the end of the calendar 
     month in which delivery is otherwise required or (ii) prevent delivery of 
     such Aircraft.  In such event, in good faith and in accordance with its 
     normal scheduling procedures, AVSA will give written notice to Northwest 
     of either (i) such delay and its related rescheduling reflecting such 
     delay(s) or (ii) such nondelivery.  Within  {CONFIDENTIAL MATERIAL OMITTED 
     AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT 
     TO A REQUEST FOR CONFIDENTIAL TREATMENT} days after Northwest's receipt of 
     such notice, Northwest (and, {CONFIDENTIAL MATERIAL OMITTED AND FILED 
     SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
     REQUEST FOR CONFIDENTIAL TREATMENT}, AVSA) may terminate this Agreement as 
     to such rescheduled or nondeliverable Aircraft by giving written notice to 
     the other party.  Such termination will discharge all obligations and 
     liabilities of the parties hereunder with respect to such affected 
     Aircraft, except that AVSA will repay to Northwest all amounts required by 
     {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES 
     AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} 
     with respect to such affected Aircraft {CONFIDENTIAL MATERIAL OMITTED AND 
     FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
     REQUEST FOR CONFIDENTIAL TREATMENT}.  Northwest will not be entitled to 
     receive such repayment nor to terminate this Agreement as to any Aircraft 
     under this Clause 10 by reason of an Excusable Delay if such delay is 
     caused solely by Northwest's negligence or Northwest's fault.

10.4 DELIVERY DATE

     If, following notice of an anticipated delay under Subclause 10.3, this
     Agreement is not terminated in accordance with the provisions of such
     Subclause (with respect to the affected Aircraft), then the date of
     delivery otherwise required hereunder will be extended by a period equal to
     the delay specified in such notice.

10.5 LOST, DESTROYED OR DAMAGED AIRCRAFT

     In the event that prior to delivery any Aircraft is lost, destroyed or
     damaged beyond economic repair, AVSA will notify Northwest in writing
     within {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
     SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
     TREATMENT} days after such event.  Such notice will specify the earliest
     date, consistent with AVSA's and the Manufacturer's other contractual
     commitments and production capabilities, by which AVSA would be able to
     deliver a replacement for such Aircraft.  This Agreement will terminate as
     to such Aircraft unless Northwest gives AVSA written notice, within
     {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
     EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} days
     after receipt by Northwest of the notice from AVSA of such loss,
     destruction or damage, that 



                                      28
<PAGE>

     Northwest desires AVSA to deliver to Northwest a replacement for such 
     Aircraft.  If Northwest gives such notice to AVSA, AVSA will deliver to 
     Northwest, at the earliest date consistent with AVSA's and the 
     Manufacturer's other contractual commitments and production capabilities, 
     an aircraft to replace the Aircraft lost, destroyed or damaged beyond 
     repair, and the parties will execute an amendment to this Agreement to 
     evidence the delivery date for such replacement aircraft; provided, 
     however, that nothing herein will obligate AVSA to deliver such 
     replacement aircraft if its manufacture would require the reactivation of 
     the Manufacturer's production line for the model of aircraft purchased 
     hereunder.  The terms and conditions of this Agreement applicable to the 
     Aircraft lost, destroyed or damaged beyond economic repair (including 
     without limitation, the price and price revision provisions in Clauses 4 
     and 5 hereof) will apply to the replacement aircraft; {CONFIDENTIAL 
     MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE 
     COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT}.  In the 
     event of termination of this Agreement as to a particular Aircraft as a 
     result of such loss, destruction or damage the obligations and liabilities 
     of the parties hereunder with respect to such Aircraft will be discharged. 
     AVSA will repay to Northwest the amount required pursuant to 
     {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES 
     AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT} 
     with respect to such lost, destroyed or damaged Aircraft {CONFIDENTIAL 
     MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE 
     COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT}.  Northwest 
     will not be entitled to receive repayment nor to terminate this Agreement 
     as to any Aircraft under this Subclause 10.5 if such loss, destruction or 
     damage is caused by Northwest's or its representatives' gross negligence 
     or willful misconduct.

10.6 REMEDIES

     THIS CLAUSE 10 {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE

12 -     WARRANTIES AND SERVICE LIFE POLICY

         AVSA, in its capacity as "Buyer" under its arrangements with the 
         Manufacturer, has negotiated and obtained the following Standard 
         Warranty, Service Life Policy, Vendor Warranties and Interface

         Northwest and that it will not enter into any amendment of the

12.1     STANDARD WARRANTY   

12.1.1   NATURE OF WARRANTY

         Subject to the limitations and conditions as hereinafter provided, 
         and except as provided in Subclause 12.1.2, the Seller warrants to 
         the Buyer that each Aircraft and each Warranted Part will at the 
         time of delivery to the Buyer:
         
            (i) be free from defects in material,

           (ii) be free from defects in workmanship, including, without
                limitation, processes of manufacture,

          (iii) be free from defects in design (including, without
                limitation, selection of materials) having regard to the
                state of the art at the date of such design, and

           (iv) be free from defects arising from failure to conform to the
                Specification, except as to those portions of the
                Specification relating to performance or where it is
                expressly stated that such portions of the Specification are 
                estimates or approximations or design aims.  

         For the purposes of this Agreement, the term "Warranted Part" will 
         mean any Seller proprietary component, equipment, accessory or part 
         that is installed on an Aircraft at the time of delivery of such 
         Aircraft and that (a) is installed on such Aircraft, (b) is 
         manufactured to the detail design of the Seller or a subcontractor 
         of it and (c) bears a part number of the Seller at the time of such 
         delivery.

12.1.2    EXCEPTIONS

          The warranties set forth in Subclause 12.1.1 will not apply to 
          Buyer Furnished Equipment, nor to the engine and its associated 
          parts, nor to any component, accessory, equipment or part purchased 
          by the Buyer that is not a Warranted Part, provided, however, that:
         
            (i)  any defect in the Seller's workmanship in respect of the
                 installation of such items in the Aircraft, including any 
                 failure by the Seller to conform to the installation 
                 instructions of the manufacturers of such items that 
                 invalidates any applicable warranty from such 
                 manufacturers, will constitute a defect in workmanship 
                 for the purpose of this Subclause 12.1 and be covered by 
                 the warranty set forth in Subclause 12.1.1(ii), and
                 
           (ii)  any defect inherent in the Seller's design of the 
                 installation, in view of the state of the art at the date 
                 of such design, that impairs the use of such items will 
                 constitute a defect in design for the purposes of this 
                 Subclause 12.1 and be covered by the warranty set forth 
                 in Subclause 12.1.1(iii). 
                 
12.1.3    WARRANTY PERIOD

          The warranties described in Subclauses 12.1.1 and 12.1.2 
          hereinabove will be limited to those defects that become apparent 
          within {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR 
          CONFIDENTIAL TREATMENT} after delivery of the affected Aircraft. 
         
12.1.4    BUYER'S REMEDY AND SELLER'S OBLIGATION 

12.1.4.1  The Buyer's remedy and the Seller's obligation and liability under
          Subclauses 12.1.1 and 12.1.2 hereinabove are limited to, at the
          Seller's expense and option, the repair, replacement or correction of,
          or the supply of modification kits rectifying the defect to, any
          defective Warranted Part.  Alternatively, the Seller may at its sole
          option furnish a credit to the Buyer for the future purchase of
          Material equal to the price at which the Buyer is then entitled to
          acquire a replacement for the defective Warranted Part. Nothing herein
          contained will obligate the Seller to correct any failure to conform
          to the Specification with respect to components, equipment,
          accessories or parts that the parties agree in writing at the time of
          delivery of the affected Aircraft are acceptable deviations or have no
          material adverse effect on the use, operation or performance of an
          Aircraft.

12.1.4.2  In the event a defect covered by Subclause 12.1.1(iii) becomes
          apparent within the applicable period set forth in Subclause
          12.1.3(ii), and the Seller is obligated to correct such defect, the
          Seller will also, if so requested by the Buyer in writing, make such

                                       35
<PAGE>

          correction in any Aircraft that has not already been delivered to the
          Buyer.  However, the Seller will not be responsible nor deemed to be
          in default on account of any delay in delivery of any Aircraft or
          otherwise, in respect of performance of this Agreement, due to the
          Seller's undertaking to make such correction and, rather than accept a
          delay in delivery of any such Aircraft, the Buyer and the Seller may
          agree to deliver such Aircraft with subsequent correction of the
          defect by the Buyer at the Seller's expense, or the Buyer may elect to
          accept delivery and thereafter file a Warranty Claim as though the
          defect had become apparent immediately after delivery of such
          Aircraft.
          
12.1.5    WARRANTY CLAIM REQUIREMENTS
          
          The Buyer's remedy and the Seller's obligation and liability under 
          this Subclause 12.1, with respect to each claimed defect, are 
          subject to the following conditions precedent:

            (i) the existence of a defect covered by the provisions of this
                Subclause 12.1,

           (ii) the defect's having become apparent within the applicable 
                warranty period, as set forth in Subclause 12.1.3, 

          (iii) the Buyer's having submitted to the Seller proof reasonably
                satisfactory to the Seller that the claimed defect is due 
                to a matter embraced within this Subclause 12.1, and that 
                such defect did not result from any act or omission of 
                the Buyer, including, but not limited to, any failure to 
                operate and maintain the affected Aircraft or part 
                thereof in accordance with the standards or any matter 
                set forth or covered in Subclause 12.1.10,
                  
           (iv) the Buyer's having returned as soon as reasonably practicable
                the Warranted Part claimed to be defective to such repair 
                facilities as may be designated by the Seller, except 
                where the Buyer elects to repair a defective Warranted 
                Part in accordance with the provisions of Subclause 
                12.1.7, and
                  
            (v) the Seller's having received a Warranty Claim fulfilling the
                conditions of and in accordance with the provisions of 
                Subclause 12.1.6 below. 

12.1.6    WARRANTY ADMINISTRATION

          The warranties set forth in Subclause 12.1 will be administered as
          hereinafter provided:

            (i) CLAIM DETERMINATION

                Warranty Claim determination by the Seller will be 
                reasonably based upon the claim details, reports from the 
                Seller's regional representative, historical data logs, 
                inspections, tests, findings during repair, defect 
                analysis and other suitable documents and information.

                sending a defective Warranted Part to the facilities 
                designated by the Seller will be borne by the Buyer 
                {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH 
                THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
                REQUEST FOR CONFIDENTIAL TREATMENT}.
                               
          (iii) RETURN OF AN AIRCRAFT

                In the event that the Buyer desires to return an Aircraft 
                to the Seller for consideration of a Warranty Claim, the 
                Buyer will notify the Seller of its intention to do so 
                and the Seller will, prior to such return, have the right 
                to inspect such Aircraft and thereafter, without 
                prejudice to its rights hereunder, to repair such 
                Aircraft, at its sole option, either at the Buyer's 
                facilities or at another place acceptable to the Seller.

                REQUEST FOR CONFIDENTIAL TREATMENT}.

           (iv) ON-AIRCRAFT WORK BY THE SELLER

                In the event that a defect necessitates the dispatch by 
                the Seller of a working team to repair or correct such 
                defect at the Buyer's facilities, or in the event that 
                the Seller accepts the return of an Aircraft to perform 
                or have performed such repair or correction, then all 
                related expenses incurred in performing such repair or 
                correction will be borne {CONFIDENTIAL MATERIAL OMITTED 
                AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE 
                COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL 
                TREATMENT}.
                
                Any work performed by the Seller to rectify defects, 
                which if performed by the Buyer would not be eligible for 
                a warranty credit under the terms of Subclause 12.1.7 
                (v), will be at the Buyer's expense.  {CONFIDENTIAL 
                MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES 
                AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR

                The Seller will perform on-Aircraft work, subject to 
                either of the following conditions being met:

           (a)  in the Seller's opinion, such work must require the technical

                      Bulletin or batch of Service Bulletins for their

                      AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR 
                      CONFIDENTIAL TREATMENT}, it being understood that for 
                      batches of Service Bulletins, the Seller will only count 
                      individual Service Bulletins with more than {CONFIDENTIAL

                        flight tests prove necessary to complete a repair 
                        under the In-house Warranty) of the Warranted Part

                   (b)  Direct material costs are determined by the prices at
                        which the Buyer acquired such material, excluding any

12.1.8    STANDARD WARRANTY TRANSFERABILITY

          The warranties provided for in this Subclause 12.1 for any 
          Warranted Part will accrue to the benefit of any airline in revenue 
          service other than the Buyer, if the Warranted Part enters into the 
          possession of any such airline as a result of a pooling or leasing 
          agreement between such airline and the Buyer or upon the Buyer's 
          sale of the Aircraft to any such airline in accordance with 
          Subclause 19.3, in accordance with the terms and subject to the 
          limitations and exclusions of the foregoing warranties and to

          Seller is liable under Subclause 12.1 has been corrected, repaired 
          or replaced pursuant to the terms of this Clause 12, the period of 
          the Seller's warranty with respect to such corrected, repaired or

          remaining portion of the original warranty in respect of such 
          corrected, repaired or replacement Warranted Part.  In the event 
          that a defect is attributable to a defective repair or replacement 
          by the Buyer, a Warranty Claim with respect to such defect will not 
          be allowable, notwithstanding any subsequent correction or repairs, 
          and will immediately terminate the remaining warranties under this 
          Subclause 12.1 in respect of the affected Warranted Part.

          (iii) any component, equipment, accessory or part from which the
                trademark, trade name, part or serial number or other
                identification marks have been removed.

          This waiver of the Seller's liability by the Buyer will not apply in
          the cases of Subclause 12.1.10 (i) and Subclause 12.1.10 (ii) above if
          the Buyer submits reasonable evidence that the defect did not arise
          from nor was contributed to by either of said cases.

12.2      SELLER SERVICE LIFE POLICY

          In addition to the warranties set forth in Subclause 12.1 above, 
          the Seller further agrees that should a Failure occur in any Item, 
          then, subject to the general conditions and limitations set forth 
          in Subclause 12.2.4 below, the provisions of this Subclause 12.2 
          will apply. 
           
12.2.1    DEFINITIONS
           
          For the purposes of this Subclause 12.2, the following definitions 
          will apply: 

12.2.1.1  "Item" means any of the Seller components, equipment, accessories or
          parts listed in Exhibit G hereto which are installed on an Aircraft at
          any time during the period of effectiveness of the Service Life Policy
          as defined below in Subclause 12.2.2.

12.2.1.2  "Failure" means any breakage of, or defect in, an Item that has
          occurred, that can reasonably be expected to occur on a repetitive or
          fleetwide basis, and that materially impairs the utility or safety of
          the Item, provided that any such breakage of, or defect in, any Item
          did not result from any breakage or defect in any other Aircraft part
          or component or from any other extrinsic force.

12.2.2    PERIODS AND SELLER'S UNDERTAKING

          Subject to the general conditions and limitations set forth in 
          Subclause 12.2.4 below, the Seller agrees that if a Failure occurs 
          in an Item within {CONFIDENTIAL MATERIAL OMITTED AND FILED 
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO 
          A REQUEST FOR CONFIDENTIAL TREATMENT} years after the delivery of 
          said Aircraft to the Buyer, the Seller will, at its own discretion, 
          as promptly as practicable and for a price that reflects the 
          Seller's financial participation in the cost as hereinafter 
          provided, either:

                                       45
<PAGE>

          
12.2.2.1  design and furnish to the Buyer a correction for such Item subject to
          a Failure and provide any parts required for such correction
          (including Seller designed standard parts but excluding industry
          standard parts unless a part of an Item), or,

12.2.2.2  replace such Item.

12.2.3    SELLER'S PARTICIPATION IN THE COST

          Any part or Item that the Seller is required to furnish to the 
          Buyer under this Service Life Policy in connection with the 
          correction or replacement of an Item will be furnished to the Buyer 
          at the Seller's current sales price therefor, less the Seller's 
          financial participation, which will be determined in accordance 
          with the following formula:

                          C  (N  -  T)      
                       -----------------
          P =                  N

          where

          P:   financial participation of the Seller,

          C:   the Seller's then current sales price for the required Item or
               required Seller designed parts,
     
          T:   total time in months, at time of Failure, since delivery of the
               particular Aircraft in which the Item subject to such Failure was
              originally installed,

          N:   {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
               SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
               CONFIDENTIAL TREATMENT} months.

12.2.4    GENERAL CONDITIONS AND LIMITATIONS

12.2.4.1  Notwithstanding Subclause 12.2.3, the undertakings given in this
          Subclause 12.2 will not be valid during the period applicable to an
          Item under Subclause 12.1. 

12.2.4.2  The Buyer's remedy and the Seller's obligation and liability under
          this Service Life Policy are subject to compliance by the Buyer with
          the following conditions precedent:

          (i) The Buyer will maintain log books and other historical
              records with respect to each Item adequate to enable 
              determination as to whether the alleged Failure is 
              covered by this Service Life Policy and, if so, to define 
              the portion of the cost to be borne by the Seller in 
              accordance with Subclause 12.2.3 above.
                   
<PAGE>

            (ii)  The Buyer will keep the Seller informed of any significant 
                  incidents relating to an Aircraft, howsoever occurring or 
                  recorded, if the failure to so inform the Seller materially 
                  prejudices the Seller's position.

           (iii)  The conditions of Subclause 12.1.10 will have been complied 
                  with.

            (iv)  The Buyer will carry out specific structural inspection 
                  programs for monitoring purposes as may be established from 
                  time to time by the Seller.  Such programs will be, to the 
                  extent possible, compatible with the Buyer's operational 
                  requirements and will be carried out at the Buyer's 
                  expense.  Reports relating thereto will be regularly 
                  furnished to the Seller.

             (v)  In the case of any breakage or defect, the Buyer will 
                  report the same in writing to the Seller within 
                  {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH 
                  THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A 
                  REQUEST FOR CONFIDENTIAL TREATMENT} days after any breakage 
                  or defect in an Item becomes apparent, whether or not said 
                  breakage or defect can reasonably be expected to occur in 
                  any other Aircraft, and the Buyer will inform the Seller in 
                  sufficient detail about the breakage or defect to enable 
                  the Seller to determine whether said breakage or defect is 
                  subject to this Service Life Policy. 

12.2.4.3  Except as otherwise provided in this Subclause 12.2, any claim under
          this Service Life Policy will be administered as provided in, and will
          be subject to the terms and conditions of, Subclause 12.1.6.

12.2.4.4  In the event that the Seller will have issued a modification
          applicable to an Aircraft, the purpose of which is to avoid a Failure,
          the Seller may elect to offer to supply to the Buyer the necessary
          modification kit free of charge {CONFIDENTIAL MATERIAL OMITTED AND
          FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT
          TO A REQUEST FOR CONFIDENTIAL TREATMENT}.  If such a kit is so offered
          to the Buyer, then, in respect of such Failure and any Failures that
          could ensue therefrom, the validity of the Seller's commitment under
          this Subclause 12.2 will be subject to the Buyer's incorporating such
          modification in the relevant Aircraft, within a reasonable time, as
          promulgated by the Seller and in accordance with the Seller's
          instructions.

12.2.4.5  THIS SERVICE LIFE POLICY IS NEITHER A WARRANTY, PERFORMANCE GUARANTEE,
          NOR AN AGREEMENT TO MODIFY ANY AIRCRAFT OR AIRFRAME COMPONENTS TO
          CONFORM TO NEW DEVELOPMENTS OCCURRING IN THE STATE OF AIRFRAME DESIGN
          AND MANUFACTURING ART.  THE SELLER'S OBLIGATION UNDER THIS SUBCLAUSE
          12.2 IS TO MAKE ONLY THOSE CORRECTIONS TO THE ITEMS OR FURNISH
          REPLACEMENTS THEREFOR AS PROVIDED IN THIS SUBCLAUSE 12.2. THE BUYER'S
          SOLE REMEDY AND RELIEF FOR THE NONPERFORMANCE OF ANY OBLIGATION OR
          LIABILITY OF THE SELLER ARISING UNDER OR BY VIRTUE OF THIS SERVICE
          LIFE POLICY WILL BE IN MONETARY DAMAGES, 


                                       47

<PAGE>

          LIMITED TO THE AMOUNT THE BUYER REASONABLY EXPENDS IN PROCURING A 
          CORRECTION OR REPLACEMENT FOR ANY ITEM THAT IS THE SUBJECT OF A 
          FAILURE COVERED BY THIS SERVICE LIFE POLICY AND TO WHICH SUCH 
          NONPERFORMANCE IS RELATED, LESS THE AMOUNT THAT THE BUYER OTHERWISE 
          WOULD HAVE BEEN REQUIRED TO PAY UNDER THIS SUBCLAUSE 12.2 IN 
          RESPECT OF SUCH CORRECTED OR REPLACEMENT ITEM. WITHOUT LIMITING THE 
          EXCLUSIVITY OF WARRANTIES AND GENERAL LIMITATIONS OF LIABILITY 
          PROVISIONS SET FORTH IN SUBCLAUSE 12.5, THE BUYER HEREBY WAIVES, 
          RELEASES AND RENOUNCES ALL CLAIMS TO ANY FURTHER DIRECT, INCIDENTAL 
          OR CONSEQUENTIAL DAMAGES, INCLUDING LOSS OF PROFITS AND ALL OTHER 
          RIGHTS, CLAIMS AND REMEDIES, ARISING UNDER OR BY VIRTUE OF THIS 
          SERVICE LIFE POLICY.

12.2.5    TRANSFERABILITY

          Except as provided in Subclause 19.3, the Buyer's rights under this 
          Subclause 12.2 will not be assigned, sold, leased, transferred or 
          otherwise alienated by operation of law or otherwise, without the 
          Seller's prior written consent. 

          Any unauthorized assignment, sale, lease, transfer or other 
          alienation of the Buyer's rights under this Service Life Policy 
          will, as to the particular Aircraft involved, immediately void this 
          Service Life Policy in its entirety.

12.3      VENDOR WARRANTIES

12.3.1    SELLER'S SUPPORT

          Prior to delivery of the first Aircraft under this Agreement, the 
          Seller will obtain from all Vendors listed in the Supplier Product 
          Support Agreements manual enforceable and transferable warranties 
          and indemnities against patent infringements for all of the 
          components, equipment, accessories and parts of the Vendors that 
          are installed in an Aircraft at the time of delivery thereof 
          ("Vendor Parts," it being understood that such term will not 
          include the Propulsion Systems, Buyer Furnished Equipment or other 
          equipment selected by the Buyer to be supplied by Vendors with whom 
          the Seller has no existing enforceable warranty agreements).  The 
          Seller will also obtain enforceable and transferable Vendor service 
          life policies from landing gear Vendors for structural landing gear 
          elements.  The Seller undertakes to supply to the Buyer such Vendor 
          warranties, Vendor service life policies and indemnities against 
          patent infringements substantially in the form summarized in the 
          Supplier Product Support Agreements manual. 



                                       48

<PAGE>

12.3.2    VENDOR'S DEFAULT

12.3.2.1  In the event that any Vendor under any standard warranty or indemnity
          against patent infringements obtained by the Seller pursuant to
          Subclause 12.3.1 or Clause 13 hereof defaults in the performance of
          any material obligation under such warranty or indemnity against
          patent infringements with respect to a Vendor Part, and the Buyer
          submits within a reasonable time to the Seller reasonable proof that
          such default has occurred, then Subclause 12.1 or Clause 13 of this
          Agreement will apply to the extent the same would have been applicable
          had such Vendor Part been a Warranted Part except that, for
          obligations covered under Subclause 12.1 {CONFIDENTIAL MATERIAL
          OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT}.

12.3.2.2  In the event that any Vendor under any Vendor service life policy
          obtained by the Seller pursuant to Subclause 12.3.1 hereof defaults in
          the performance of any material obligation with respect thereto, and
          the Buyer submits within reasonable time to the Seller reasonable
          proof that such default has occurred, then Subclause 12.2 of this
          Agreement will apply to the extent the same would have been applicable
          had such component, equipment, accessory or part been listed in
          Exhibit G hereto.

12.3.2.3  At the Seller's request, the Buyer will assign to the Seller, and the
          Seller will be subrogated to, all of the Buyer's rights against the
          relevant Vendor, with respect to and arising by reason of such default
          and the Buyer will provide reasonable assistance to enable the Seller
          to enforce the rights so assigned.

12.4      INTERFACE COMMITMENT

12.4.1    INTERFACE PROBLEM

          If the Buyer experiences any technical problem in the operation of 
          an Aircraft or its systems due to a malfunction {CONFIDENTIAL 
          MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND 
          EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL 
          TREATMENT}, the cause of which, after due and reasonable 
          investigation, is not readily identifiable by the Buyer, but which 
          the Buyer reasonably believes to be attributable to the design 
          characteristics of one or more components of the Aircraft (an 
          "Interface Problem"), the Seller will, if requested by the Buyer, 
          and without additional charge to the Buyer, except for 
          transportation of the Seller's personnel to the Buyer's facilities, 
          promptly conduct or have conducted an investigation and analysis of 
          such problem to determine, if possible, the cause or causes of the 
          problem and to recommend such corrective action as may be feasible, 
          provided, however, that if the Seller determines, after such due 
          and reasonable investigation, that the Interface Problem was due to 
          or caused by any default by the Buyer in performance of its 
          obligations hereunder, the Buyer will pay to the Seller all 
          reasonable costs and expenses incurred by the Seller during such 
          investigation.  The 

                                       49

<PAGE>

          Buyer will furnish to the Seller all data and information in the 
          Buyer's possession relevant to the Interface Problem and will 
          cooperate with the Seller in the conduct of the Seller's 
          investigations and such tests as may be required.

          At the conclusion of such investigation the Seller will promptly 
          advise the Buyer in writing of the Seller's opinion as to the cause 
          or causes of the Interface Problem and the Seller's recommendations 
          as to corrective action.

12.4.2    SELLER'S RESPONSIBILITY

          If the Seller determines that the Interface Problem is primarily 
          attributable to the design of a Warranted Part, the Seller will, if 
          requested by the Buyer, correct the design of such Warranted Part, 
          pursuant to the terms and conditions of Subclause 12.1.

12.4.3    VENDOR'S RESPONSIBILITY

          If the Seller determines that the Interface Problem is primarily 
          attributable to the design of a component, equipment, accessory or 
          part other than a Warranted Part ("Vendor Component"), the Seller 
          will, if requested by the Buyer, reasonably assist the Buyer in 
          processing any warranty claim the Buyer may have against the 
          manufacturer of such Vendor Component.

12.4.4    JOINT RESPONSIBILITY

          If the Seller determines that the Interface Problem is attributable 
          partially to the design of a Warranted Part and partially to the 
          design of any Vendor Component, the Seller will, if requested by 
          the Buyer, seek a solution to the Interface Problem through 
          cooperative efforts of the Seller and any Vendor involved.  The 
          Seller will promptly advise the Buyer of such corrective action as 
          may be proposed by the Seller and any such Vendor. Such proposal 
          will be consistent with any then existing obligations of the Seller 
          hereunder and of any such Vendor to the Buyer.  Such corrective 
          action, when reasonably accepted by the Buyer, will constitute full 
          satisfaction of any claim the Buyer may have against either the 
          Seller or any such Vendor with respect to such Interface Problem.

12.4.5    GENERAL

12.4.5.1  All requests under this Subclause 12.4 will be directed both to the
          Seller and the affected Vendors. 

12.4.5.2  Except as specifically set forth in this Subclause 12.4, this
          Subclause 12.4 will not be deemed to impose on the Seller any
          obligations not expressly set forth elsewhere in this Agreement.

12.4.5.3  All reports, recommendations, data and other documents furnished by
          the Seller to the Buyer pursuant to this Subclause 12.4 will be deemed
          to be delivered under this Agreement and will be subject to the terms,
          covenants and conditions set forth in this Clause 12 and in Subclause
          22.4.

12.5      EXCLUSIVITY OF WARRANTIES AND 
          GENERAL LIMITATIONS OF LIABILITY

          THIS CLAUSE 12 (INCLUDING ITS SUBPROVISIONS) SETS FORTH THE 
          EXCLUSIVE WARRANTIES, EXCLUSIVE LIABILITIES AND EXCLUSIVE 
          OBLIGATIONS OF THE SELLER, AND THE EXCLUSIVE REMEDIES AVAILABLE TO 
          THE BUYER, WHETHER UNDER THIS AGREEMENT OR OTHERWISE, ARISING FROM 
          ANY DEFECT OR NONCONFORMITY OR PROBLEM OF ANY KIND IN ANY AIRCRAFT, 
          COMPONENT, EQUIPMENT, ACCESSORY, PART OR SERVICE DELIVERED UNDER 
          THIS AGREEMENT.

          THE BUYER RECOGNIZES THAT THE RIGHTS, WARRANTIES AND REMEDIES IN 
          THIS CLAUSE 12 ARE ADEQUATE AND SUFFICIENT TO PROTECT THE BUYER 
          FROM ANY DEFECT OR NONCONFORMITY OR PROBLEM OF ANY KIND IN THE 
          GOODS AND SERVICES SUPPLIED UNDER THIS AGREEMENT.  THE BUYER HEREBY 
          WAIVES, RELEASES AND RENOUNCES ALL OTHER WARRANTIES, OBLIGATIONS, 
          GUARANTEES AND LIABILITIES OF THE SELLER AND ALL OTHER RIGHTS, 
          CLAIMS AND REMEDIES OF THE BUYER AGAINST THE SELLER, WHETHER 
          EXPRESS OR IMPLIED BY CONTRACT, TORT, OR STATUTORY LAW OR 
          OTHERWISE, WITH RESPECT TO ANY NONCONFORMITY OR DEFECT OR PROBLEM 
          OF ANY KIND IN ANY AIRCRAFT, COMPONENT, EQUIPMENT, ACCESSORY, PART 
          OR SERVICE DELIVERED UNDER THIS AGREEMENT, INCLUDING BUT NOT 
          LIMITED TO:

          (1)  ANY IMPLIED WARRANTY OF MERCHANTABILITY AND/OR FITNESS FOR ANY 
               GENERAL OR PARTICULAR PURPOSE;

          (2)  ANY IMPLIED OR EXPRESS WARRANTY ARISING FROM COURSE OF 
               PERFORMANCE, COURSE OF DEALING OR USAGE OF TRADE;

          (3)  ANY RIGHT, CLAIM OR REMEDY FOR BREACH OF CONTRACT;

          (4)  ANY RIGHT, CLAIM OR REMEDY FOR TORT, UNDER ANY THEORY OF 
               LIABILITY, HOWEVER ALLEGED, INCLUDING, BUT NOT LIMITED TO, 
               ACTIONS AND/OR CLAIMS FOR NEGLIGENCE, GROSS NEGLIGENCE, 
               INTENTIONAL ACTS, WILLFUL DISREGARD, IMPLIED WARRANTY, PRODUCT 
               LIABILITY, STRICT LIABILITY OR FAILURE TO WARN;

<PAGE>

          (5)  ANY RIGHT, CLAIM OR REMEDY ARISING UNDER THE UNIFORM 
               COMMERCIAL CODE OR ANY OTHER STATE OR FEDERAL STATUTE;

          (6)  ANY RIGHT, CLAIM OR REMEDY ARISING UNDER ANY REGULATIONS OR 
               STANDARDS IMPOSED BY ANY INTERNATIONAL, NATIONAL, STATE OR 
               LOCAL STATUTE OR AGENCY;

          (7)  ANY RIGHT, CLAIM OR REMEDY TO RECOVER OR BE COMPENSATED FOR:

               (a)  LOSS OF USE OR REPLACEMENT OF ANY AIRCRAFT, COMPONENT, 
                    EQUIPMENT, ACCESSORY OR PART PROVIDED UNDER THIS AGREEMENT;

               (b)  LOSS OF, OR DAMAGE OF ANY KIND TO, ANY AIRCRAFT, COMPONENT,
                    EQUIPMENT, ACCESSORY OR PART PROVIDED UNDER THIS AGREEMENT;

               (c)  LOSS OF PROFITS AND/OR REVENUES;

               (d)  ANY OTHER INCIDENTAL OR CONSEQUENTIAL DAMAGE.

          THE WARRANTIES AND SERVICE LIFE POLICY PROVIDED BY THIS AGREEMENT 
          WILL NOT BE EXTENDED, ALTERED OR VARIED EXCEPT BY A WRITTEN 
          INSTRUMENT SIGNED BY THE SELLER AND THE BUYER.  IN THE EVENT THAT 
          ANY PROVISION OF THIS CLAUSE 12 SHOULD FOR ANY REASON BE HELD 
          UNLAWFUL, OR OTHERWISE UNENFORCEABLE, THE REMAINDER OF THIS CLAUSE 
          12 WILL REMAIN IN FULL FORCE AND EFFECT.

12.6      DUPLICATE REMEDIES

          The remedies provided to the Buyer under this Clause 12 as to any 
          defect in respect of the Aircraft or any part thereof are mutually 
          exclusive and not cumulative.  The Buyer will be entitled to the 
          remedy that provides the maximum benefit to it, as the Buyer may 
          elect, pursuant to the terms and conditions of this Clause 12 for 
          any such particular defect for which remedies are provided under 
          this Clause 12; provided, however, that the Buyer will not be 
          entitled to elect a remedy under one part of this Clause 12 that 
          constitutes a duplication of any remedy elected by it under any 
          other part hereof for the same defect.  The Buyer's rights and 
          remedies herein for the nonperformance of any obligations or

          any such particular defect for which remedies are provided under 
          this Clause 12; provided, however, that Northwest will not be 
          entitled to elect a remedy under one part of this Clause 12 that 
          constitutes a duplication of any remedy elected by it under any 
          other part hereof for the

          amount Northwest expends in procuring a correction or replacement 
          for any covered part subject to a defect or nonperformance covered 
          by this Clause 12, and Northwest will not have any right to require

          reason of infringement of a patent covered by Subclause 13.1, the 
          Seller will, at its option and expense, either (i) procure for the 
          Buyer the right to use such part free of any liability for patent 
          infringement or (ii) as soon as possible replace such part with a 
          noninfringing substitute otherwise complying with the requirements 
          of this Agreement.

13.3      SELLER'S OBLIGATION

          The Seller's obligation hereunder with respect to any actual or 
          alleged infringement is conditioned upon commencement of suit

          written claim alleging infringement, and upon written notice by the 
          Buyer to the Seller within {CONFIDENTIAL MATERIAL OMITTED AND FILED 
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO 
          A REQUEST FOR CONFIDENTIAL TREATMENT} days after receipt by the

          claim, giving particulars thereof.  The Seller will have the option 
          but not the obligation at any time to conduct negotiations with the 
          party or parties charging infringement and may intervene in any 
          suit commenced.  Whether or not the Seller intervenes in any such 
          suit, it will be entitled at any stage of the proceedings to 
          assume, conduct or control the defense thereof.

17-       VENDORS' PRODUCT SUPPORT

17.1      VENDOR PRODUCT SUPPORT AGREEMENTS

17.1.1    AVSA has obtained product support agreements transferable to Northwest
          from Vendors of Seller Furnished Equipment listed in the Specification
          ("Product Support Agreements").

17.1.2    These Product Support Agreements are based on the "World Airlines and
          Suppliers Guide" and include Vendor commitments as contained in the
          Supplier Product Support Agreements with respect to warranties and
          guarantees (copies of which have been provided to Northwest).

17.2      VENDOR COMPLIANCE

          AVSA will monitor Vendor compliance with support commitments defined 
          in the Product Support Agreements and will take remedial action 
          together with Northwest if requested by Northwest in writing.

17.3      VENDOR PART REPAIR STATIONS

17.3.1    The Manufacturer has developed with the Vendors a program aimed at
          building a comprehensive network of repair stations in North America
          for those Vendor Parts originating from outside this territory.

17.3.2    As a result of the above, most Vendor Parts are now repairable in
          North America, and corresponding repair stations are listed in a
          document, the AOG and Repair Guide, which is issued and regularly
          updated by the Manufacturer.

          Vendor Parts that have to be repaired outside North America will be 
          sent by Northwest to {CONFIDENTIAL MATERIAL OMITTED AND FILED 
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO 
          A REQUEST FOR CONFIDENTIAL TREATMENT}. All such Vendor Parts will 
          be returned to Northwest with all applicable FAA tagging.

17.3.3    AVSA will support Northwest in cases where the agreed repair turn time
          of an approved repair station is not met by causing free-of-charge
          loans or exchanges (as specified in the relevant Supplier Product
          Support Agreements manual) to be offered to Northwest.

18-       BUYER FURNISHED EQUIPMENT AND DATA 

18.1      INSTALLATION AND DELIVERY

18.1.1    Without additional charge, and in accordance with the Specification,
          AVSA will cause the Manufacturer to provide for the installation of
          the Buyer Furnished Equipment.

18.1.2    AVSA will cause the Manufacturer to advise Northwest of the dates by
          which, in the planned release of engineering for an Aircraft, the
          Manufacturer reasonably requires a written detailed description of the
          dimensions and weight of Buyer Furnished Equipment for such Aircraft
          and information necessary for the installation and operation thereof,
          and Northwest will furnish such detailed description and information
          by the dates so specified.  Such dimensions and weights will not
          thereafter be revised unless mutually agreed and set forth in an SCN.

18.1.3    AVSA will also cause the Manufacturer to furnish in sufficient time to
          Northwest a schedule of dates by and locations to which Buyer
          Furnished Equipment for such Aircraft must be delivered to the
          Manufacturer to permit installation in and delivery of such Aircraft
          in accordance with the delivery schedule referred to in Clause 9.
          Northwest will furnish such equipment to the Manufacturer at such
          locations by such dates.  Northwest, at its own expense,  will also
          furnish or cause to be present at the works where such Buyer Furnished
          Equipment is to be installed, when reasonably requested by the
          Manufacturer, field service representatives to provide the
          Manufacturer technical advice regarding the installation and
          calibration of Buyer Furnished Equipment.

18.2      SPECIFICATION AND AIRWORTHINESS APPROVALS

          Northwest warrants that all Buyer Furnished Equipment (other than
          Buyer Furnished Equipment manufactured by the Manufacturer) will meet
          the requirements of the Specification, will comply with applicable LBA
          and FAA regulations and will be approved by the LBA and the FAA for
          installation and use on an Aircraft at the time of delivery of such
          Aircraft.  AVSA will bear no expense in connection with adjusting and
          calibrating Buyer Furnished Equipment to the extent necessary to
          obtain LBA and FAA approval,  unless such work is due to an Aircraft
          Interface Problem, mishandling or excessive use on the part of AVSA or
          the Manufacturer.

18.3      DELAY AND NONPERFORMANCE

          Any delay or failure in complying with the warranty in the foregoing
          Subclause 18.2, in providing the descriptive information and services
          mentioned in Subclause 18.1 hereof, in furnishing the Buyer Furnished
          Equipment or in obtaining any required approval of such equipment 
          under the LBA or FAA regulations will be the responsibility of 
          Northwest, to the extent that such delay or failure will in turn,

         (i)  delay the performance of any act to be performed by or on behalf
              of AVSA or the Manufacturer, or


                                      64

<PAGE>


        (ii) cause the Final Contract Price of the Aircraft to be increased by 
             the amount of AVSA's additional reasonable and substantiated costs,
             if any, attributable to such delay or failure by Northwest, 
             including, without limitation, storage, taxes, insurance and costs
             of out-of-sequence installation,

          and any resulting cost will be borne by Northwest.

          Further, in any such event, AVSA shall give written notice to 
          Northwest and, unless Northwest has cured such noncompliance within
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE

          to take any of the actions set forth below in Subclauses 18.3.2, 
          18.3.3 or 18.3.4.

18.3.2    At Northwest's request, AVSA will be entitled to cause the
          Manufacturer to purchase and install the Buyer Furnished Equipment
          involved, in which event the Final Contract Price of the affected
          Aircraft will be increased by the purchase price of such Buyer
          Furnished Equipment plus reasonable costs and expenses incurred by the
          Manufacturer for handling charges, transportation, insurance,
          packaging and, if so required and not already provided for in the
          Final Contract Price of such Aircraft, for adjustment and calibration.

18.3.3    If (i) delivery of the Buyer Furnished Equipment is delayed by more
          than {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} days after the date specified by the
          Manufacturer for the delivery of such Buyer Furnished Equipment or
          (ii) the Buyer Furnished Equipment required to obtain certification of
          the Aircraft in accordance with Subclause 2.3 hereof is not approved
          by the LBA or the FAA within {CONFIDENTIAL MATERIAL OMITTED AND FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
          REQUEST FOR CONFIDENTIAL TREATMENT} days after the date specified by
          the Manufacturer for the delivery of such Buyer Furnished Equipment,
          then, notwithstanding the terms of Subclause 2.3, AVSA will be
          entitled to deliver the affected Aircraft where it is then located
          with no obligation to install such Buyer Furnished Equipment.  Upon
          such delivery AVSA will be relieved of all obligations to install such
          Buyer Furnished Equipment.

18.3.4    If (i) the Buyer Furnished Equipment is delayed by more than
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT} days after the date specified by the
          Manufacturer for the delivery of such Buyer Furnished Equipment or
          (ii) the Buyer Furnished Equipment is not required for certification
          of the Aircraft and is not approved by the LBA or the FAA within
          {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE

<PAGE>

          date specified by the Manufacturer for the delivery of such Buyer 
          Furnished Equipment, then AVSA will be entitled to deliver the 
          Aircraft with no obligation to install such Buyer Furnished 
          Equipment.  Northwest may also elect to have the Aircraft so 
          delivered, whereupon AVSA will be relieved of all obligations to 
          install such Buyer Furnished Equipment.

18.4      Any Buyer Furnished Equipment installed on an Aircraft and
          subsequently removed due to the fault of Northwest will be removed at
          Northwest's expense.

18.5      TAX-FREE ZONES

          Northwest will cause all Buyer Furnished Equipment to be delivered at
          its own expense to the following address, unless AVSA notifies 
          Northwest otherwise in writing.

          For all Buyer Furnished Equipment

              Kreetslag 10
              21129 HAMBURG
              GERMANY

18.6      RISK OF LOSS

          Title to and risk of loss of Buyer Furnished Equipment will at all
          times remain with Northwest.  When Buyer Furnished Equipment is in the
          possession of AVSA, AVSA will have only such responsibility therefor
          as is chargeable by law to a bailee for hire, but will not be liable
          for loss of use. {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY
          WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
          CONFIDENTIAL TREATMENT}.

18.7      AVSA-SUPPLIED BUYER FURNISHED EQUIPMENT

          If Northwest requests AVSA to cause the Manufacturer to supply
          directly certain items that are considered Buyer Furnished Equipment
          pursuant to the Specification, and if compliance with such request by
          AVSA and the Manufacturer in their judgment will not affect the
          delivery date of an Aircraft referred to in Clause 9, then AVSA will
          order such items subject to the execution of an SCN reflecting the
          effect on price and any other items and conditions of this Agreement.
          In such a case, AVSA will be entitled to the payment of a reasonable
          handling charge and will bear no liability in respect of product
          support commitments assumed by the Vendor of such Buyer Furnished
          Equipment.  The provisions of Subclauses 18.2 and 18.3 will apply to
          Buyer Furnished Equipment covered under this Subclause 18.7 except in
          the event of any delay in approval or delivery of such Buyer Furnished
          Equipment attributable to the action of AVSA, the Manufacturer or the
          Associated Contractor.

19.1 SUCCESSORS AND ASSIGNS

     Subject to the provisions of this Clause 19, this Agreement shall inure to
     the benefit of and be binding upon the successors and assigns of the
     parties hereto.  This Agreement and/or the rights of either party hereunder
     will not be assigned or transferred in any manner whatsoever, in whole or
     in part, by either party without the prior written consent of the other

     institutions providing financing for the purchase of particular Aircraft 
     by Northwest hereunder with respect to such Aircraft and to the extent 
     reasonably required to effect such financing, so long as the duties and 
     obligations of AVSA hereunder are not changed and Northwest remains 
     primarily and directly liable for all obligations of the "Buyer" 
     hereunder. Notwithstanding the foregoing, Northwest may assign its rights 
     hereunder to any Affiliate of Northwest without the prior written consent 
     of AVSA if prior to or concurrently with such assignment (x) Northwest 
     executes and delivers to AVSA an instrument in writing confirming to AVSA 
     that Northwest remains liable for all obligations, liabilities and 
     responsibilities of the "Buyer" hereunder and (y) such Affiliate executes
     and delivers to AVSA an instrument in writing confirming to AVSA that such 
     Affiliate assumes all obligations, liabilities and responsibilities of the
     "Buyer" hereunder and agrees that it will remain an Affiliate of Northwest 
     so long as any Aircraft subject to such assignment remains to be delivered 
     hereunder.

     Notwithstanding the definition of Affiliate, for the exclusive purpose of 
     this Subclause 19.1, the term "Affiliate" shall include any person or 
     entity in connection with joint venture operations between Northwest and 
     KLM Royal Dutch Airlines "KLM".

     Notwithstanding anything herein to the contrary, AVSA may at any time
     without Northwest's consent, assign any of its rights to receive money and
     any of its duties to effect the sale and delivery of any Aircraft or any of
     its responsibilities, duties or obligations to perform any other
     obligations hereunder to the Manufacturer, any of the Associated
     Contractor, ASCO or to any Affiliate of the Seller, the Manufacturer or any
     Associated Contractor {CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY
     WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR

     or particular personnel of the Manufacturer, ASCO, any of the Associated
     Contractors or any Affiliate of the Manufacturer or any Associated
     Contractor at which or by whom the services to be performed under this
     Agreement will be performed.  AVSA may also designate the Manufacturer, any

     delivery thereof to Northwest, and subject to the delivery to AVSA of
     reasonable financial guarantees and protections and other terms as AVSA may
     reasonably require, Northwest's rights with respect to such Aircraft solely
     under Clauses 12, 13 and 17 and this Subclause 19.3 of  this Agreement,
     will inure to the benefit of such purchaser or lessee, as the case may be. 
     Northwest will furnish to AVSA a true copy of such agreement with such
     purchaser or lessor, clearly stating that such purchaser or lessor
     acknowledges that it is bound by and will comply with all applicable terms,
     conditions and limitations of this Agreement.  No assignment under this
     Subclause 19.3 shall be deemed to increase AVSA's obligations.

     Where

     Pn   =    Revised Base Price of the Airframe at delivery of the Aircraft.

     Pb   =    Base Price of the Airframe (including Nacelles and Thrust
               Reversers, if applicable) at economic conditions December
               1996/January 1997/February 1997 averaged (January 1998 delivery
               conditions).

     F    =    (0.005 x N x Pb) Where  N = The calendar year of delivery of the
               Aircraft minus 1998.

     ECIn =    The arithmetic average of the latest published values available
               at the date of A319 Aircraft delivery for ECI-SIC-3721W for the
               11th, 12th and 13th months prior to the month of delivery of the
               Aircraft (1 decimal), where the quarterly value for the third
               month of a quarter (March, June, September and December) will be
               deemed to apply for the two preceding months.

5.   GENERAL PROVISIONS

5.1  SUBSTITUTION OF INDEXES

     In the event that:

     (i)   the US Department of Labor substantially revises the methodology of
           calculation of any of the indexes referred to hereinabove, or

     (ii)  the US Department of Labor discontinues, either temporarily or
           permanently, any of the indexes referred to hereinabove, or

     (iii) the data samples used to calculate any of the indexes referred to
           hereinabove are substantially changed,

     the most nearly comparable index published by a recognized financial
     institution, financial publication or university shall be used as a
     substitute index.

     Such substitute index will reflect as closely as possible the actual
     variations of the wages or of the material costs, as the case may be, used
     in the calculation of the original index.

     As a result of this selection of a substitute index, the price revision
     formula will be adjusted for the successive utilization of the original
     index and of the substitute index.

5.2  FINAL INDEX VALUES

     The Revised Base Price at the date of Aircraft delivery will be final and
     will not be subject to further adjustments of any kind and for any reason
     to the applicable indexes as published at the date of Aircraft delivery.

          HEn  =    HE SIC 3724 for the sixth month prior to the month of
                    delivery of the A319 Aircraft; the quotient HEn/11.16 is
                    rounded to the nearest third decimal place.  The product by
                    0.55 is rounded to the nearest second decimal place.

          ICn  =    IC-Index for the sixth month prior to the month of delivery
                    of the A319 Aircraft. 

          MMPn  =   MMP-Index for the sixth month prior to the month of delivery
                    of the A319 Aircraft. The product by 0.25 is rounded to the
                    nearest second decimal place.

          EPn  =    EP-Index for the sixth month prior to the month of delivery
                    of the A319 Aircraft.

     The Composite Price Index shall be determined to the second decimal place. 
     If the next succeeding decimal place is five (5) or more, the preceding
     decimal figure shall be raised to the next higher figure.  

     The final factor shall be rounded to the nearest thousandth (3 decimals).

5.   GENERAL PROVISIONS

5.1  The Revised Reference Price at delivery of the A319 Aircraft shall be the
     final price and will not be subject to further adjustments in the indexes.

5.2  If no final index value is available for any of the applicable months, the
     published preliminary figures will be the basis on which the Revised
     Reference Price will be computed.

5.3  If the US Department of Labor substantially revises the methodology of
     calculation of the indexes referred to in this Exhibit E or discontinues
     any of these indexes, AVSA shall, in agreement with CFM International,
     apply a substitute for the revised or discontinued index, such substitute
     index to lead in application to the same adjustment result, insofar as
     possible, as would have been achieved by continuing the use of the original
     index as it may have fluctuated had it not been revised or discontinued.  

     Appropriate revision of the formula shall be made to accomplish this
     result.

5.4  Should the above escalation provisions become null and void by action of
     the US Government, the Reference Price shall be adjusted to reflect
     increases in the cost of labor, material and fuel which have occurred from
     the period represented by the applicable Reference Price Indexes to the
     sixth month prior to the scheduled delivery of the A319 Aircraft.

5.5  The Revised Reference Price at delivery of the A319 Aircraft in no event
     shall be less than the Reference Price defined in Paragraph 1 of this
     Exhibit E.

     Where

     Pn   =    Revised Reference Price of a set of two (2) engines at delivery
               of the A320 Aircraft.

     Pb   =    Reference Price as defined above.

     CPIn      =    Composite Price Index for the sixth month prior to the month
                    of delivery of the A320 Aircraft.

          Said Composite Price Index is composed as follows:

     CPIn =    0.55 (HEn   x 100) + 0.10 ICn + 0.25 MMPn + 0.10 EPn 
                     ---

          HEn  =    HE SIC 3724 for the sixth month prior to the month of
                    delivery of the A320 Aircraft; the quotient HEn/11.16 is
                    rounded to the nearest third decimal place.  The product by
                    0.55 is rounded to the nearest second decimal place.

          ICn  =    IC-Index for the sixth month prior to the month of delivery
                    of the A320 Aircraft. 

          MMPn  =   MMP-Index for the sixth month prior to the month of delivery
                    of the A320 Aircraft. The product by 0.25 is rounded to the
                    nearest second decimal place.

          EPn  =    EP-Index for the sixth month prior to the month of delivery
                    of the A320 Aircraft.

     The Composite Price Index shall be determined to the second decimal place. 
     If the next succeeding decimal place is five (5) or more, the preceding
     decimal figure shall be raised to the next higher figure.  

     The final factor shall be rounded to the nearest thousandth (3 decimals).

<PAGE>

5.   GENERAL PROVISIONS 

5.1  The Revised Reference Price at delivery of the A320 Aircraft shall be the
     final price and will not be subject to further adjustments in the indexes.

5.2  If no final index value is available for any of the applicable months, the
     published preliminary figures will be the basis on which the Revised
     Reference Price will be computed.

5.3  If the US Department of Labor substantially revises the methodology of
     calculation of the indexes referred to in this Appendix 4 or discontinues
     any of these indexes, AVSA shall, in agreement with CFM International,
     apply a substitute for the revised or discontinued index, such substitute
     index to lead in application to the same adjustment result, insofar as
     possible, as would have been achieved by continuing the use of the original
     index as it may have fluctuated had it not been revised or discontinued.  

     Appropriate revision of the formula shall be made to accomplish this
     result.

5.4  Should the above escalation provisions become null and void by action of
     the US Government, the Reference Price shall be adjusted to reflect
     increases in the cost of labor, material and fuel which have occurred from
     the period represented by the applicable Reference Price Indexes to the
     sixth month prior to the scheduled delivery of the A320 Aircraft.

5.5  The Revised Reference Price at delivery of the A320 Aircraft in no event
     shall be less than the Reference Price defined in Paragraph 1 of this
     Appendix 4.

          (c) THIRD CLOSING.  On the terms and subject to the conditions of this
Agreement, on September 29, 1999 (the "THIRD CLOSING DATE") KLM agrees to

                                                                               7

          (g)  ACCELERATION OPTION.  (i)  NWA Corp. shall have the option, at
any time and from time to time after the Initial Closing Date and on prior
written notice to KLM, to accelerate, either in whole or in part in the manner
specified in the next sentence, the purchase of Shares that would otherwise
occur on subsequent Closing Dates so that the accelerated purchase will occur on
a date (the "ACCELERATION DATE") specified in such notice (such date to be at
least 30 days after the date the notice is provided to KLM), at which date the
purchase and sale of the Shares whose purchase and sale is being accelerated as
designated in the notice referred to above shall be effected at the applicable
Per Share Prices specified in Section 2.1, as adjusted in accordance with
Section 2.1(e).  If NWA Corp. elects to accelerate pursuant to this Section
2.1(g) the purchase of only part of the Shares remaining to be purchased, it may
do so only by accelerating the purchase of all of the Shares scheduled to be
purchased on the Third Closing Date and (if the Second Closing Date has not yet
occurred) the Second Closing Date, in which event the Fourth Closing Date will
be accelerated to occur one year after the Acceleration Date.  Following any
such acceleration option, the provisions of Sections 2.2 and 2.3 shall continue
in effect as though no accelerated purchase and sale had occurred, as follows:

          (a)  To the extent an adjustment would otherwise be required pursuant
     to Section 2.2 with respect to Shares whose purchase has already occurred
     on an accelerated basis pursuant to this Section 2.1(g), on the date (the
     "TRANSACTION ACCELERATED DATE") to which such subsequent Closing Date would
     have otherwise been accelerated pursuant to Section 2.2(e) or consideration
     would otherwise be received by KLM pursuant to Section 2.2(f), NWA Corp.
     will make a payment to KLM equal to the product of (A) the number of Shares
     whose purchase would have otherwise been accelerated to the Transaction
     Accelerated Date but for an earlier acceleration pursuant to Section
     2.1(g), times (B) the excess, if any, of (x) the Transactional Value Per
     Share over (y) the regularly scheduled Per Share Price at which such Shares
     would have been purchased pursuant to Section 2.1(a) through (d) at the
     regularly scheduled subsequent Closing Date without giving effect to such
     acceleration.

          (b)  To the extent an adjustment would otherwise be required pursuant
     to Section 2.3 with respect to Shares whose purchase has already occurred
     on an accelerated basis pursuant to this Section 2.1(g), on the regularly
     scheduled subsequent Closing Date on which the higher purchase price would
     have otherwise been payable pursuant to Section 2.3, NWA Corp. will make a
     payment to KLM equal to the product of (A) the number of Shares previously
     purchased on an accelerated basis pursuant to Section 2.1(g) whose purchase
     price would have otherwise been increased pursuant to Section 2.3, times
     (B) the excess, if any, of the higher weighted average price that would
     otherwise apply pursuant to Section 2.3 over the regularly scheduled Per
     Share Price at which such Shares would have been purchased pursuant to
     Section 2.1(a) through (d) at the regularly scheduled subsequent Closing
     Date without giving effect to such acceleration.

          (ii) Notwithstanding the foregoing, NWA Corp. may not accelerate any
purchase of Shares pursuant to this Section 2.1(g) if (a) the condition set
forth in Section



<PAGE>

                                                                               8

5.2(b)(ii)(A) has not been satisfied, or (b) Northwest Airlines, Inc.'s right to
terminate the Alliance Termination Agreement because of the imposition of
restrictions at Schiphol Airport, as set forth in the letter agreement dated as
of September 29, 1997 between Northwest Airlines, Inc. and KLM (the "HUB
RESTRICTIONS LETTER"), has not either expired by the passage of time or been
waived by Northwest Airlines, Inc.

          (iii)      NWA Corp. shall indemnify and hold harmless KLM, on an
after-tax basis, from any taxes imposed under the laws of The Netherlands in
respect of a payment made to KLM pursuant to Section 2.1(g)(i)(a) or (b) which
would not have been imposed had the purchase and sale of Shares not been
accelerated pursuant to this Section 2.1(g) and had the provisions of Section
2.2 or 2.3, as applicable, applied pursuant to their terms.  KLM will seek
indemnity under this Section 2.1(g)(iii) only after attempting in good faith and
failing to achieve the same consequences under the tax laws of The Netherlands
for a payment made to KLM pursuant to Section 2.1(g)(i)(a) or (b) as the tax
consequences that apply to consideration received by KLM under Section 2.2 or
2.3.


          2.2 EFFECT OF CONTROL TRANSACTION. (a)  NWA Corp. will notify KLM as
promptly as practicable of the pendency of any transaction that is reasonably
likely to constitute a Control Transaction; PROVIDED, that NWA Corp. shall not
be obligated to so notify KLM prior to such transaction having been publicly
announced (except as otherwise specifically provided for in the Standstill
Agreement).  Additionally, upon the consummation of a Control Transaction, NWA
Corp. will on the date of such consummation notify KLM thereof.

          (b) In connection with any Control Transaction consummated prior to
June 30, 1999, there shall be a determination of the Transactional Value Per
Share.  The "TRANSACTIONAL VALUE PER SHARE" is the weighted average
consideration to be received in respect of each Share transferred or sold in, or
otherwise receiving a distribution in connection with, such Control Transaction,
valued, (i) in the case of cash, at the face amount thereof, (ii) in the case of
securities registered under the Exchange Act and as to which there is a
previously established public trading market, (A) if such security is listed on
the New York Stock Exchange or American Stock Exchange, the average of the
closing price during the ten trading days immediately prior to the date of
consummation thereof or (B) if such security is included in the NASDAQ National
Market System, the weighted average price at which all trades of such securities
are reported on the NASDAQ National Market System during the ten trading days
immediately prior to the date of consummation thereof, (iii)  in the case of
securities as to which there is a previously established public trading market
on a non-U.S. exchange or automated quotation system, the average of the closing
price (if quoted in a foreign currency, converted into Dollars at the then-
prevailing market Dollar exchange rate) during the ten trading days immediately
prior to the date of consummation thereof, and (iv) in the case of other
securities or property, at the fair market value thereof established in
accordance with Section 2.2(c) as of the date of consummation thereof.



<PAGE>

                                                                               9

          (c) NWA Corp. and KLM will attempt to agree on the value of securities
or other property described in clause (iii) of paragraph (b) above.  If they
cannot reach agreement within 15 days after the definitive terms of the Control
Transaction have been publicly announced or, if earlier, 15 days after notice to
KLM, NWA Corp. and KLM will each promptly engage an investment banking firm to
perform valuations of such securities or other property and to attempt to agree
on their value.  If such firms are unable to agree on a valuation within 10 days
after they have both been so engaged, such firms shall promptly jointly select a
third nationally recognized investment banking firm to perform its own valuation
of such securities or other property, which valuation shall be determinative.

          (d) If any such Transactional Value Per Share (as finally determined
in accordance with this Section 2.2) is higher than the Per Share Price
otherwise payable on Closing Dates scheduled to occur after the consummation of
such Control Transaction, the obligations of the parties under Section 2.1 with
respect to the Shares to be purchased on each such subsequent Closing Date will
be adjusted in accordance with the following provisions.

          (e) Subject to the provisions in Sections 2.2(f) and (g) below, if a
Control Transaction is consummated in which the related Transactional Value Per
Share is higher than the Per Share Price for any subsequent Closing Date, then
each such Closing Date that has a lower Per Share Price will be accelerated to
occur on, or as promptly as practicable after, the date of consummation of such
transaction, and the per share purchase price to be paid in Cash for each Share
whose purchase and sale is being so accelerated will be equal to the
Transactional Value Per Share.  The obligations of the parties with respect to
any Closing Date scheduled to occur after such consummation date whose Per Share
Price is equal to or greater than the Transactional Value Per Share will remain
unchanged.  NWA Corp. shall notify KLM as promptly as practicable of each date,
if any, on which the accelerated payment of the purchase price for Shares will
be made hereunder and its good faith estimate of the related Transactional Value
Per Share (the "ACCELERATION NOTICE"), but in no event later than 20 days prior
to the date of payment.

          (f) Notwithstanding the provisions in Section 2.2(e), the effect of
the following Control Transactions in which the related Transactional Value Per
Share is higher than the Per Share Price for any subsequent Closing Date shall
be as follows:  (i) if such Control Transaction involves a cash tender offer for
any and all shares of Common Stock, NWA Corp. may elect (which election may be
made as part of the Acceleration Notice and in any event shall be made as
promptly as practicable prior to the consummation of such tender offer, but in
no event later than 20 days prior to the date of payment) to direct KLM to
tender the Shares whose purchase and sale would otherwise be accelerated
hereunder into such tender offer and, upon the consummation date of such tender
offer and the payment for each Share at the Transactional Value Per Share, the
obligations of the parties to purchase and sell Shares on such subsequent
Closing Date or Dates that involve such lesser Per Share Price will be deemed to
have been discharged and no accelerated purchase and sale between the parties
will occur; (ii) if such Control Transaction consists of a merger or
consolidation transaction where all of the outstanding shares of Common Stock
are to be converted into the right to receive cash, upon the consummation of
such Control Transaction and the payment for each Share at the



<PAGE>

                                                                              10

Transactional Value Per Share, the obligations of the parties to purchase and
sell Shares on such subsequent Closing Date or Dates at such lesser Per Share
Price will be deemed to have been discharged and no accelerated purchase and
sale between the parties will occur; and (iii) subject to the provisions in
Section 2.2(g), if such Control Transaction involves a transaction where part of
the transaction consideration consists of securities or other property, NWA
Corp. may elect (which election may be made as part of the Acceleration Notice
and in any event shall be made as promptly as practicable prior to the
accelerated purchase date on which NWA Corp. would otherwise be required to
purchase the affected Shares pursuant to Section 2.2(e) above, but in no event
later than 20 days prior to the date of consummation) to have KLM, upon the
consummation of such Control Transaction, receive and retain the transaction
consideration that is to be paid in respect of such affected Shares and upon the
payment for each of the Shares at the Transactional Value Per Share and the
obligations of the parties to purchase and sell such affected Shares on such
subsequent Closing Date or Dates at such lesser Per Share Price will be deemed
to have been discharged and no accelerated purchase and sale between the parties
will occur.  Absent such election by NWA Corp., the provisions of Section 2.2(e)
shall apply.

          (g) Notwithstanding the provisions in Section 2.2(f)(iii), if (i) the
Per Share Price for any subsequent Closing Date is less than the Transactional
Value Per Share for a Control Transaction and (ii) NWA Corp. makes the election
provided for in Section 2.2(f)(iii), then KLM, upon written notice delivered to
NWA Corp. within 10 days after NWA Corp. has provided notice of such election to
KLM, may waive KLM's right to receive and retain the higher Transactional Value
Per Share at the time and in the form provided in Section 2.2(f)(iii) and, in
lieu thereof, KLM will receive the Per Share Price for the affected Shares at
the times and in the amounts scheduled under Section 2.1 for each remaining
Closing Date, without regard to any higher Transactional Value Per Share.

          2.3 EFFECT OF CERTAIN ISSUANCES OF COMMON STOCK.  If within one year
after the Initial Closing Date NWA Corp. issues new shares of common stock in
one or more primary offerings for cash at a weighted average offering price in
excess of any of the respective Per Share Prices set forth in Section 2.1, then
the purchase price for each Share being purchased on each such subsequent
Closing Date will be increased to such higher weighted average price; PROVIDED,
there will be no adjustments to any subsequent purchase price for Shares
pursuant to this Section 2.3 if the aggregate number of shares of common stock
offered in such primary offerings during such one-year period is less than
6,550,851 shares (as appropriately adjusted in respect of stock splits,
subdivisions and combinations); PROVIDED, FURTHER, that for purposes of this
Section 2.3, the issuance of Common Stock upon the exercise of employee stock
options shall not constitute a primary offering.

          (c) Neither the execution and delivery of this Agreement or the
     Ancillary Agreements or the performance by KLM of the transactions
     contemplated hereby or thereby will (i) violate or conflict with any of the
     provisions of the charter or other organizational documents of KLM, (ii)
     with or without the giving of notice or the lapse of time or both, violate

     lease, contract, agreement, license or other instrument or any provision of
     any law, order, judgment, decree, restriction or ruling of any governmental
     authority to which KLM is a party or by which any of its property is bound
     or (iii) result in the creation of any liens, encumbrances, equities or
     claims upon any of the Shares currently owned by it or to be acquired by it
     upon exercise of the KLM Option, other than pursuant to this Agreement.

          (d) No consent, approval, authorization or order of, or filing or
     registration with, any court or governmental agency or body or any other

     administrative or regulatory proceedings, charges, complaints or
     investigations pending or, to the best knowledge of KLM, threatened against
     KLM, and KLM is not a party to, or subject to or bound by, any order,
     judgment, injunction, stipulation, award or decree (whether rendered by a
     court or administrative agency or by arbitration), in any such case, which
     could, individually or in the aggregate, materially adversely affect the
     ability of KLM to consummate the transactions contemplated hereby and by
     the Ancillary Agreements.

          (f) KLM has, and on the Initial Closing Date and each subsequent
     Closing Date KLM will have, good and valid title to the Shares to be

     and the performance of the transactions herein and therein contemplated to
     be performed by NWA Corp. have been duly authorized by the Board of
     Directors of NWA Corp. and no further corporate action on the part of NWA

          (c) Neither the execution and delivery of this Agreement and the

     of trust, lease, contract, agreement, license or other instrument or any
     provision of any law, order, judgment, decree, restriction or ruling of any

          (f) Neither NWA Corp. nor any of its officers, directors, employees or

     is defined in, the Rights Agreement of NWA Corp. dated as of November 16,
     1995, as amended (the "RIGHTS AGREEMENT").

          (h) The "capital" of NWA Corp. is not "impaired" and will not become
     "impaired" as a result of the purchase of the Shares from KLM by NWA Corp.
     on the Initial Closing Date, within the meaning of Section 160(a) (1) of
     the Delaware General Corporation Law, as amended (the "DGCL").  The
     "capital" of NWA Corp. would not become "impaired", within the meaning of
     Section 160(a) (1) of the DGCL, in the event the obligations of NWA Corp.
     to purchase Shares under this Agreement were accelerated and NWA Corp.
     purchased all 24,977,874 shares of Common Stock owned by KLM at the
     applicable purchase prices specified in Section 2.1 on the date hereof,
     after giving effect to (and assuming consummation of) the transactions
     contemplated by the Preferred Stock Agreement, the BTNY Preferred Stock
     Repurchase Agreement, dated as of September 29, 1997 (the "BTNY PREFERRED
     STOCK AGREEMENT", between NWA Corp. and BTNY, and the Blum Preferred Stock

     STOCK AGREEMENT"), between NWA Corp. and Blum.


                                   ARTICLE IV

                                    COVENANTS

          4.1 NO TRANSFERS, LIENS. (a)  KLM hereby unconditionally and
irrevocably agrees that it will not sell, transfer, or assign, or enter into any
equity swap or similar arrangement with respect to, any Shares subject to
purchase by NWA Corp. under this Agreement; PROVIDED, HOWEVER, that the
foregoing shall not apply to Shares that are no longer subject to purchase by
NWA Corp. under this Agreement by reason of early termination or otherwise.  KLM
will not create, incur, assume or suffer to exist any Lien on any of the Shares,
including any proceeds or profits therefrom, except as provided in paragraph (b)
below or Liens otherwise created pursuant to this Agreement.

          (b) In the event that KLM notifies NWA Corp. of its desire to assign
or pledge to a financial institution, as security for a borrowing proposed to be
made by KLM, any or all of the proceeds to be received from NWA Corp. on any
subsequent Closing Date from the sale of Shares, then KLM and NWA Corp. will
negotiate in good faith with regard to the establishment of mutually acceptable
arrangements whereby the Shares will be placed in escrow with an escrow agent
pending their sale to NWA Corp., and such financial institution will receive a
pledge of KLM's right to receive cash paid by NWA Corp. into such escrow for
Shares on a Closing Date as provided herein.   Such assignment and pledge of
proceeds may not be made by KLM until NWA Corp. and KLM have executed and
delivered to each other a mutually acceptable escrow agreement and the Shares
are deposited in escrow with the escrow agent thereunder.  This paragraph is
intended to provide a means for KLM to assign or pledge the proceeds to be paid
to KLM upon the sale of Shares pursuant to this Agreement.  Under no
circumstances will KLM be permitted to create, incur, assume or suffer to exist
any Lien upon Shares themselves, and such escrow arrangements may not otherwise
affect NWA Corp.'s rights or obligations under this Agreement.

          4.2 LEGENDS.  In furtherance of the agreements contained in Sections
2.1 and 4.1, KLM hereby agrees that the certificate or certificates representing
the Shares beneficially owned by it shall bear the following legend:

          THE SHARES [DESCRIBE ANY OTHER SECURITIES] REPRESENTED BY THIS
          CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF THE COMMON STOCK
          REPURCHASE AGREEMENT DATED AS OF SEPTEMBER 29, 1997 (THE "AGREEMENT")
          BETWEEN NORTHWEST AIRLINES CORPORATION (THE "CORPORATION") AND
          KONINKLIJKE LUCHTVAART MAATSCHAPPIJ N.V. ("KLM"), WHICH PROVIDES THAT
          (I) THE SHARES [SECURITIES] ARE SUBJECT TO REPURCHASE BY THE
          CORPORATION AND (II) KLM IS PROHIBITED FROM TRANSFERRING, SELLING,
          ASSIGNING, EXCHANGING, MORTGAGING, PLEDGING, HYPOTHECATING OR
          OTHERWISE DISPOSING OF THESE SHARES [SECURITIES] EXCEPT TO THE
          CORPORATION. IN ADDITION, UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE
          AGREEMENT, THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
          AUTOMATICALLY CONVERTED, WITHOUT ANY ACTION ON THE PART OF KLM, FROM
          SHARES OF CLASS A COMMON STOCK INTO SHARES OF CLASS B COMMON STOCK.  A
          COPY OF THE AGREEMENT IS ON FILE AND AVAILABLE FOR INSPECTION AT THE
          PRINCIPAL OFFICES OF THE CORPORATION.

KLM agrees that, concurrently with the execution and delivery of this Agreement
and from time to time as subsequently may be required, it will cooperate with
NWA Corp. in arranging for the replacement of the existing legends with the
foregoing legend on all of the certificates representing the Shares beneficially
owned by KLM.  Notwithstanding the foregoing, NWA Corp. agrees to the removal of
the foregoing legend from any Shares which will no longer be subject to this
Agreement (such removal to be effected on or as promptly as practicable after
the date such Shares will no longer be subject to this Agreement), including as
a result of any termination of this Agreement.

          4.3 GOVERNANCE AND OTHER AGREEMENTS.  Effective upon consummation of
the transactions contemplated by this Agreement on the Initial Closing Date but
subject to the Standstill Agreement, all of KLM's rights and obligations under
the Stockholders' Agreement and any and all other corporate governance rights
involving NWA Corp., including without limitation the agreement (the "BOARD
AGREEMENT") dated as of December 23, 1993 with respect to the designation by KLM
of members of the Board of Directors, will be terminated.  Notwithstanding the
foregoing but subject to the Standstill Agreement, KLM will retain the right to
vote with respect to all of the Shares prior to the purchase and sale of such
Shares on a related Closing Date.

          4.4 CONSENT OF SERIES A PREFERRED AND SERIES B PREFERRED.  KLM
reaffirms its previously delivered consent, delivered in its capacity as a
holder of Series A Preferred and

                                                                              16

Series B Preferred, to the repurchase by NWA Corp. of Common Stock, including
pursuant to this Agreement.  NWA Corp. agrees to solicit from the other holder
of Series B Preferred its irrevocable consent to the repurchases of Common Stock
contemplated hereby.

          4.5 ANTITRUST IMMUNITY AND EUROPEAN COMMUNITY CONDITIONS.  Each of KLM
and NWA Corp. hereby agrees to use commercially reasonable efforts to achieve
the satisfaction of the condition set forth in Section 5.2(b)(ii) hereto.

          4.6 NO STOCK SPLITS, ETC.  Prior to the Initial Closing Date, NWA
Corp. will not subdivide, combine or otherwise reclassify its Common Stock, or
declare or pay any dividend in respect of its Common Stock.  After the Initial
Closing Date and until the termination or expiration of this Agreement, (a) NWA
Corp. shall not engage in any of the following transactions unless the Board of
Directors shall have determined reasonably and in good faith, in accordance with
applicable provisions of corporation law, that after giving effect to such
transactions and all related transactions being effected in connection
therewith, and assuming the remaining unfulfilled obligations of NWA Corp. to
purchase Shares under this Agreement were accelerated and NWA Corp. purchased
such Shares at the applicable purchase prices in Section 2.1 on the date of such
determination, the capital of NWA Corp. would not be "impaired" within the
meaning of Section 160(a)(1) of the DGCL:  (i) subdivide, combine or otherwise
reclassify its Common Stock; (ii) declare or pay any dividend or make or pay any
other distribution in respect of its Common Stock; (iii) redeem or repurchase
any of its capital stock (other than pursuant to this Agreement, the Preferred
Stock Agreement, the BTNY Preferred Stock Agreement, and the Blum Preferred
Stock Agreement); (iv) directly or indirectly capitalize any surplus; (v) make
any change in the par value of its common stock; or (vi) engage in, or permit
any of its subsidiaries to engage in, any merger, consolidation,
recapitalization, liquidation or other business combination transaction; and (b)
NWA Corp. shall not enter into any agreements containing, or amend any agreement
to include, covenants or other provisions that directly or indirectly prohibit
NWA Corp. from purchasing Shares under this Agreement.

          4.7 DISMISSAL OF PENDING SUITS.  KLM consents and agrees to the
dismissal with prejudice of all of its claims against all of the other parties
in the Pending Suits, effective on the purchase of the Shares on the Initial
Closing Date, and, at the Initial Closing Date, KLM will file a stipulation of
dismissal in each of the Pending Suits, dismissing all such claims with
prejudice and providing that each party will bear its own costs, including
attorney's fees.

          4.8 RELEASE.  Each party hereto fully and forever releases and
discharges, effective on the purchase of the Shares on the Initial Closing Date,
the other party hereto and its present and former directors and officers,
predecessors, successors, subsidiaries, parents, affiliates, agents, servants,
employees, attorneys, representatives and assigns from all actions, causes of

          5.2 CONDITIONS TO SUBSEQUENT CLOSING DATES. (a)  The obligations of
NWA Corp. to make the payment called for at a particular subsequent Closing Date
shall be subject to the satisfaction (or waiver by NWA Corp.) of the following
conditions:

               (i)    NO INJUNCTIONS, ETC.  No injunction or temporary 
     restraining order shall have been issued and remain in force which 
     restrains, prohibits or invalidates the closing at such subsequent 
     Closing Date.

               (ii)   NO CAPITAL IMPAIRMENT.  The Board of Directors shall not 
     have determined reasonably and in good faith, in accordance with applicable
     provisions of corporation law, that the capital of NWA Corp. is impaired on
     such subsequent Closing Date or would otherwise be impaired as a result of
     the payment by NWA Corp. for the requisite Shares on such subsequent
     Closing Date within the meaning of the DGCL; PROVIDED, HOWEVER, that NWA
     Corp. shall purchase the maximum number of the Shares due to be purchased
     at such subsequent Closing Date as specified in Section 2.1 which can be
     purchased at the applicable Per Share Price provided in Section 2.1 without
     impairing its capital; PROVIDED, FURTHER, that in making any such
     determination as to a capital impairment, the Board of Directors shall,
     consistent with its fiduciary duties, (a) employ the same methods employed
     by it at the September 4, 1997 meeting of the Board of Directors (the
     "SEPTEMBER 4 MEETING") with respect to the transactions contemplated by
     this Agreement, including engaging an independent financial advisor that
     regularly engages in rendering opinions to boards of directors concerning
     the types of issues which typically arise in the report of Houlihan Lokey
     Howard & Zukin referenced below, who shall provide a similar written
     presentation and opinion to the Board of Directors, and employ similar
     analyses and methodologies, as those provided and employed by Houlihan
     Lokey Howard & Zukin in its report delivered at the September 4 Meeting,
     and (b) receive such other presentations, opinions, analyses and use
     methodologies as such financial advisor or the Board of Directors shall
     then deem reasonably appropriate.  NWA Corp. shall provide to KLM copies of
     the relevant minutes of the Board of Directors' meetings and the written
     presentations and opinions of such financial advisor(s) which relate to
     each such subsequent determination as to capital impairment for purposes of
     subsequent Closing Dates.

               (iii)  GOOD AND VALID TITLE.  KLM shall have and deliver to
     NWA Corp. good and valid title to all of the property comprising the Shares
     to be purchased by NWA Corp. at such subsequent Closing Date and any later
     Closing Date, free and clear of any Liens.

          (b) The obligations of KLM to effect the purchase of Shares on a
particular subsequent Closing Date shall be subject to the satisfaction (or
waiver by KLM) of the following conditions:

               (i)    NO INJUNCTIONS, ETC.  No injunction or temporary 
     restraining order shall have been issued and remain in force which 
     restrains, prohibits or invalidates the closing at such subsequent 
     Closing Date.

               (ii)   ANTITRUST APPROVALS.  In the case of the Third Closing
     Date and the Fourth Closing Date, (A) the antitrust immunity presently
     granted to the Northwest/KLM commercial alliance by the U.S. Department of
     Transportation pursuant to Order 93-1-11 shall have been renewed or
     otherwise maintained or such antitrust immunity shall have been renewed
     and/or modified on terms as favorable in all material respects as the terms
     of the antitrust immunity granted to (1) the United-Lufthansa commercial
     alliance by the U.S. Department of Transportation pursuant to Order 96-5-27
     and (2) the Delta/Swissair/Austrian/Sabena commercial alliance by the U.S.
     Department of Transportation pursuant to Order 96-6-33 and (B) the European
     Commission shall not have imposed conditions on the Northwest/KLM
     commercial alliance equivalent to the conditions proposed with respect to
     the pending commercial alliance between British Airways and American
     Airlines, the terms of which were reported in the media on or about August
     and/or September of 1997 prior to the date hereof such that KLM's and
     Northwest Airlines, Inc.'s abilities to operate as contemplated in the
     Alliance Implementation Agreement shall have been materially adversely
     affected, PROVIDED that, if this condition remains unsatisfied by the 180th
     day after the scheduled Third Closing Date or Fourth Closing Date, as the
     case may be, KLM shall be required to either (x) waive this condition with
     respect to the applicable Closing Date or (y) terminate this Agreement, but
     only with respect to the obligations of the parties for the Third Closing
     Date and the Fourth Closing Date or the Fourth Closing Date, as the case
     may be, pursuant to Section 7.1(b) (assuming in the case of clause (y) that
     KLM is not otherwise in material breach of this Agreement and the sole
     remaining unsatisfied condition to KLM's obligations hereunder is contained
     in this Section 5.2(b)(ii) (except for any injunction or temporary
     restraining order referred to in Section 5.2(b)(i) that relates to the same
     antitrust immunity or conditions of the European Commission that cause the
     condition of this Section 5.2(b)(ii) to remain unsatisfied)).


               (iii)  HUB RESTRICTIONS.  In the case of the Third Closing Date 
     and the Fourth Closing Date, Northwest Airlines, Inc. shall not have 
     exercised its right under the Hub Restrictions Letter to terminate the 
     Alliance Implementation Agreement because of the imposition of restrictions
     at Schiphol Airport; PROVIDED, that if this condition remains unsatisfied 
     by the 30th day after delivery to KLM by Northwest Airlines, Inc. pursuant 
     to the Hub Restrictions Letter of its written notice of termination of the
     Alliance Implementation Agreement, KLM shall be required to either (x)
     waive this condition with respect to the Third Closing Date and the Fourth
     Closing Date or (y) terminate this Agreement, but only with respect to the
     obligations of the parties for the Third Closing Date and the Fourth
     Closing Date pursuant to Section 7.1(b) (assuming in the case of clause (y)
     that KLM is not otherwise in material breach of this Agreement).

          (c)  If KLM has delivered to Northwest Airlines, Inc. a notice under
Section 1.04(b) of the Alliance Implementation Agreement of a Material Default
on the part of Northwest Airlines, Inc. (as such term is used in such
Agreement), the parties' obligations to effect the purchase and sale of Shares
on a particular subsequent Closing Date may, at the sole

                                                                              22

option of KLM, be deferred pending either (i) Northwest Airlines, Inc.'s cure of
such Material Default or (ii) a determination by the arbitrator(s) appointed
pursuant to Section 9.08 of the Alliance Implementation Agreement that no such
Material Default exists.  Immediately upon the occurrence of either of the
events specified in the preceding clauses (i) or (ii), the parties shall be
obligated to effect the purchase and sale of Shares which had been deferred by
reason of this Section 5.2(c).  If such arbitrator(s) make a determination that
a Material Default on the part of Northwest Airlines, Inc. exists but KLM does
not thereafter give notice of termination of the Alliance Implementation
Agreement within the three-month period specified in Section 1.04 of such
Alliance Implementation Agreement, then immediately upon the expiration of such
three-month period, the parties shall be obligated to effect the purchase and
sale of Shares which had been deferred by reason of this Section 5.2(c).


                                   ARTICLE VI

                                WITHHOLDING TAXES

          6.1 UNITED STATES FEDERAL WITHHOLDING TAXES. (a)  NWA Corp. hereby
agrees that it will not deduct or withhold any United States federal income
taxes that may be imposed under Sections 881(a) and 1442 of the Internal Revenue
Code of 1986, as amended (the "CODE") (or any similar successor provisions)
("UNITED STATES WITHHOLDING TAXES") from any payments made by NWA Corp. to KLM
in respect of the Shares.

          (b) Except to the extent provided in Section 6.1(c) below, NWA Corp.
hereby agrees to indemnify and hold harmless KLM from and against any United
States Withholding Taxes that are imposed on KLM on or in respect of any
payments made by NWA Corp. to KLM in respect of the Shares to the extent that
such taxes are imposed on KLM solely as a result of NWA Corp.'s repurchase of
NWA Corp. stock from any person other than KLM or as a result of an increase or
decrease in the number of Shares purchased requested by NWA Corp. pursuant to
Section 6.1(d).

          (c) KLM will deliver to NWA Corp., promptly after the date hereof, an
Internal Revenue Service Form 1001 evidencing 4that KLM is entitled to the
benefits of the income tax treaty between The Netherlands and the United States.
KLM also agrees to furnish, to the extent it is legally entitled to do so, NWA
Corp. with such documents and certificates as NWA Corp. may reasonably request
in connection with obtaining a reduction in, or exemption from, the payment of
United States Withholding Taxes imposed on any amount paid by NWA Corp. to KLM
in respect of the Shares.  NWA Corp. shall have no obligation to indemnify or
hold harmless KLM for any of the United States federal income withholding taxes
described in Section 6.1(b) above to the extent that such taxes are imposed on
KLM as a result of KLM's failure to provide any form, document or certificate
required to be provided by KLM in accordance with this Section 6.1(c).

          (d) KLM agrees to consider in good faith a request by NWA Corp. to
increase or decrease the number of Shares to be purchased on the Second Closing
Date, the Third

                                                                              23

Closing Date or the Fourth Closing Date as necessary in order for each purchase
and sale of Shares to qualify as a substantially disproportionate redemption of
stock under section 302(b)(2) of the Internal Revenue Code of 1986, as amended,
on such subsequent Closing Date; PROVIDED, HOWEVER, that in no event shall KLM
be obligated to consider a request to reduce the number of Shares to be
purchased at the final Closing Date below 10% of the then outstanding shares of
common stock of NWA Corp.

          (e) KLM hereby agrees to indemnify and hold harmless NWA Corp. from
and against any United States Withholding Taxes imposed on NWA Corp. in respect
of any payments made by NWA Corp. to KLM in respect of the Shares to the extent
that such taxes would not have been imposed but for KLM's acquisition of
additional shares of NWA Corp. stock and/or the attribution of ownership of any
NWA Corp. stock to KLM under Section 318 of the Code (or any similar successor
provision).  If KLM's (including its Affiliates) ownership of NWA Corp. stock
for purposes of Section 318 of the Code is accurately described in this
Agreement and the Preferred Stock Agreement, then NWA Corp. acknowledges that it
will have no indemnity claim against KLM pursuant to this Section 6.1(e) with
respect to the attribution of ownership of any NWA Corp. stock to KLM under
Section 318 of the Code.


                                   ARTICLE VII

                               GENERAL PROVISIONS

          7.1 TERMINATION OR ABANDONMENT OF AGREEMENT. (a)  This Agreement may
be terminated or abandoned at any time prior to the Initial Closing by mutual
consent of the parties in writing.

          (b) By written notice to NWA Corp., this Agreement may be terminated
by KLM, but only with respect to the obligations of the parties for the Third
Closing Date and the Fourth Closing Date or the Fourth Closing Date, as the case
may be, if either (i) the condition set forth in Section 5.2(b)(ii) remains
unsatisfied by the 180th day after the scheduled Third Closing Date or the
Fourth Closing Date, as the case may be (provided that KLM is not otherwise in
material breach of this Agreement), or (ii) the condition set forth in Section
5.2(b)(iii) is unsatisfied, provided that KLM's right to terminate this
Agreement pursuant to this Section 7.1(b)(ii) will lapse if it has not been
exercised prior to 30 days after delivery to KLM by Northwest Airlines, Inc.
pursuant to the Hub Restrictions Letter of its written notice of termination of
the Alliance Implementation Agreement.

          (c) By written notice to NWA Corp., this Agreement may be terminated
by KLM with respect to the obligations of the parties for any subsequent Closing
Date scheduled to occur after the date of such notice if, prior to the date of
such notice and after requisite notice and opportunity to cure having been
provided to Northwest Airlines, Inc. in accordance with the terms of the
Alliance Implementation Agreement, KLM has exercised its right under the
Alliance Implementation Agreement to terminate such Alliance Implementation
Agreement



<PAGE>

                                                                              24

as a result of a Material Default on the part of Northwest Airlines, Inc. (as
such term is defined in such Alliance Implementation Agreement), any arbitration
proceedings under Section 9.08 of such Alliance Implementation Agreement have
been concluded and such Alliance Implementation Agreement has been terminated in
accordance with its terms.

          (d) Except as otherwise specified in this Article VII, in the event of
any termination of this Agreement as provided in this Section 7.1, this
Agreement shall forthwith become wholly void and of no further force and effect
and there shall be no liability on the part of NWA Corp. or KLM or their
respective directors, officers or stockholders with respect to any obligations
set forth in this Agreement; PROVIDED, HOWEVER, that nothing in this Section 7.1
shall relieve any party from liability for any breach of its representations,
warranties, covenants or agreements contained in this Agreement.

          (e) If there is a termination of the obligations of the parties with
respect to the Third Closing Date and the Fourth Closing Date or the Fourth
Closing Date, as the case may be, pursuant to either Section 7.1(b)(i) or
7.1(b)(ii), (i) all Shares held by KLM at such time shall be automatically
converted into Class B Common Stock and shall not be reconverted into Class A
Common Stock so long as such Shares are held or reacquired by KLM or any of its
Affiliates (and KLM shall, concurrently with the execution and delivery of this
Agreement, execute and deliver a separate power-of-attorney in the form of
Exhibit D hereto that irrevocably appoints Douglas M. Steenland, Esq. (with full
power of substitution) as its agent and attorney-in-fact to execute and deliver
on behalf of KLM any and all instruments, agreements and other documents that
are necessary or advisable to permit NWA Corp. to make appropriate notations in
its stock transfer and other ownership records to reflect such conversion), and
(ii) NWA Corp. shall have the right to immediately terminate the Alliance
Implementation Agreement, within 30 days after such termination of the
obligations of the parties with respect to the Third Closing Date and the Fourth
Closing Date or the Fourth Closing Date, as the case may be.  Upon any sale or
other transfer by KLM of Class B Common Stock to a party that is not an
Affiliate, agent or nominee of KLM, such shares shall be reconverted into Class
A Common Stock.

          (f)  In the event of any termination of this Agreement pursuant to
Section 7.1(c) in which the obligations of the parties are terminated for the
Second Closing Date, the Third Closing Date and the Fourth Closing Date, on the
date of the termination of this Agreement NWA Corp. shall pay to KLM in Cash
$30,410,947.82 plus accretion on such amount at the rate of 5% per annum from
September 29, 1998 to the actual date of payment.  In the event of any such
termination of this Agreement pursuant to Section 7.1(b) or 7.1(c) in which the
obligations of the parties are terminated for the Third Closing Date and the
Fourth Closing Date, on the date of the termination of this Agreement NWA Corp.
shall pay to KLM in Cash $28,344,658.46 plus accretion on such amount at the
rate of 5% per annum from September 29, 1999 to the actual date of payment.  In
the event of any termination of this Agreement pursuant to Section 7.1(b) or
7.1(c) in which the obligations of the parties are terminated for only the
Fourth Closing Date, on the date of the termination of this Agreement NWA Corp.
shall pay to KLM in Cash $24,771,297.10 plus accretion on such amount at the
rate of 5% per annum from September 29, 2000 to the actual date of payment.
Payments made pursuant to

this Section 7.1(f) will be deemed to be additional purchase price payments to
KLM by NWA Corp. in respect of Shares which will have been, by the time of any
such payment, transferred to NWA Corp. hereunder.  NWA Corp. shall indemnify and
hold harmless KLM, on an after-tax basis, from any additional taxes for which
KLM becomes liable as a result of payments being made pursuant to this Section
7.1(f).  This Section 7.1(f) shall survive any termination of this Agreement and
shall continue in full force and effect until all amounts due from NWA Corp.
have been paid in full.  Accretion shall be calculated on the basis of the
actual number of days elapsed divided by 360 for purposes of this Agreement.

          7.2 EXPENSES.  All fees, commissions and other expenses incurred by
any party hereto in connection with the negotiation of this Agreement, the
Ancillary Agreements and the other transactions contemplated hereby, including
any fees and expenses of their respective counsel and financial advisors, shall
be borne by the party incurring such fee or expense.

          7.3 EXECUTION IN COUNTERPARTS.  This Agreement may be executed in one
or more counterparts, all of which shall be considered one and the same
agreement, and shall become a binding agreement when one or more counterparts
have been signed by each party and delivered to the other parties.

accrued dividend income under Section 305(c) of the Internal Revenue Code of
1986, as amended, or analogous provisions.

         (b) Except to the extent provided in Section 5.1(c) below, NWA Corp.
hereby agrees to indemnify and hold harmless KLM from and against any United
States Withholding Taxes that are imposed on KLM on or in respect the Series A
Purchase Price and/or the Series B Purchase Price to the extent that such taxes
are imposed on KLM solely as a result  of NWA Corp.'s repurchase of NWA Corp.
stock from any person other than KLM.

         (c) Prior to NWA Corp.'s payment of such amounts, KLM will deliver to
NWA Corp. an Internal Revenue Service Form 1001 evidencing that it is entitled
to the benefits of the income tax treaty between the Kingdom of The Netherlands
and the United States.  KLM also agrees to furnish, to the extent it is legally
entitled to do so, NWA Corp. with such documents and certificates as NWA Corp.
may reasonably request in connection with obtaining a reduction in, or exemption
from, the payment of United States federal income withholding taxes imposed on
or with respect to the Series A Purchase Price or the Series B Purchase Price.
NWA Corp. shall have no obligation to indemnify or hold harmless KLM for any
United States Withholding Taxes (i) actually withheld by NWA Corp. pursuant to
Section 5.1(a) above, or (ii) described in Section 5.1(b) above, to the extent
that such taxes are imposed on KLM as a result of KLM's failure to provide any
form, document or certificate required to be provided by KLM in accordance with
this Section 5.1(c).

         (d) KLM hereby agrees to indemnify and hold harmless NWA Corp. from
and against any United States Withholding Taxes imposed on NWA Corp. in respect
of any payments made by NWA Corp. to KLM in respect of the Series A Preferred
Shares and/or the Series B Preferred Shares to the extent that such taxes would
not have been imposed but for KLM's acquisition of additional shares of NWA
Corp. stock and/or the attribution of ownership of any NWA Corp. stock to KLM
under Section 318 of the Code (or any similar successor provision).  If KLM's
(including its Affiliates) ownership of NWA Corp. stock for purposes of Section
318 of the Code is accurately described in this Agreement and the


                                         -9-

Common Stock Agreement, then NWA Corp. acknowledges that it will have no
indemnity claim against KLM pursuant to this Section 6.1(d) with respect to the
attribution of ownership of any NWA Corp. stock to KLM under Section 318 of the
Code.

         (e)  KLM hereby represents and warrants that it is entitled to the
benefits of the income tax treaty between the Kingdom of the Netherlands and the
United States and that, under such treaty, KLM is entitled to a reduction from
30% to 5% in the rate at which United States Withholding Tax is imposed on any
dividends received by KLM from NWA Corp.  Without limiting NWA Corp.'s indemnity
obligations set forth in Section 5.1(b) above, in the event that this
representation is not correct, NWA Corp. will have no indemnity obligation to
KLM in respect of the United States Withholding Taxes described in Section
5.1(a) above.

the provisions of this Agreement by the other party without the necessity of

     to occur under the Common Stock Agreement on the Initial Closing Date (the
     date on which the KLM Option is exercised being referred to as the "KLM
     OPTION EXERCISE DATE").

          (b)  The exercise price for the Option Shares subject to the KLM

     payment of the applicable KLM Option Exercise Price for such Option Shares,
     a certificate or certificates representing the shares of Series A Preferred
     Stock and Series B Preferred Stock comprising such KLM Option Exercise
     Price.  Such certificates shall be duly endorsed in blank or accompanied by
     stock powers duly executed in blank, with all necessary stock transfer

     rights with respect to any "Put Options" arrangements that were previously

     unexercised basis without any liability in respect thereof."
