                       US AIRWAYS GROUP, INC.
       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                           (UNAUDITED)


1.  BASIS OF PRESENTATION

     The accompanying Condensed Consolidated Financial Statements 
include the accounts of US Airways Group, Inc. ("US Airways Group" 
or the "Company") and its wholly-owned subsidiaries US Airways, 
Inc. ("US Airways"), Piedmont Airlines, Inc., PSA Airlines, Inc., 
Allegheny Airlines, Inc., US Airways Leasing and Sales, Inc., US 
Airways Fuel Corporation, Material Services Company, Inc. and The 
OR Group, Inc. ( "OR Group").

     OR Group was a wholly-owned subsidiary of US Airways Group 
that was incorporated in February 1996 and dissolved in the fourth 
quarter of 1996. OR Group provided resource allocation consulting 
services and decision-making support systems to US Airways, which 
assumed these activities upon OR Group's dissolution.

     US Airways terminated its Airline Technical Services, LLC 
joint venture with a subsidiary of British Airways Plc. ("British 
Airways") effective January 1997. No material charges resulted 
from its termination.

     Management believes that all adjustments necessary for a fair 
statement of results have been included in the Condensed 
Consolidated Financial Statements for the interim periods 
presented, which are unaudited. All significant intercompany 
accounts and transactions have been eliminated. The preparation of 
financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and 
liabilities and disclosure of contingent assets and liabilities at 
the date of the financial statements and the reported amounts of 
revenues and expenses during the reporting period. Actual results 
could differ from those estimates.

     Certain 1996 amounts have been reclassified to conform with 
1997 classifications.

     These interim period Condensed Consolidated Financial 
Statements should be read in conjunction with the Consolidated 
Financial Statements contained in the Company's Annual Report on 
Form 10-K for the year ended December 31, 1996.

2.  INCOME PER COMMON SHARE

     For the three months and nine months ended September 30, 
1997, approximately 2,685,000 incremental shares of Common Stock 
were included in the calculation of fully diluted income per 
common share as the result of applying the "treasury stock method" 
to outstanding stock options. For the three months ended September 
30, 1997, the effects of assuming conversion of the Series H 
Senior Cumulative Preferred Stock ("Series H Preferred Stock") and 
the Series B Preferred Stock (for shares that were outstanding 
prior to the conversion and redemption activity discussed in Note 
4(a)) were dilutive and therefore included in the calculation. For 
the nine months ended September 30, 1997, the effects of assuming 
conversion of the Company's outstanding preferred stock issuances 
(for shares that were outstanding prior to the repurchase, 
conversion and redemption activity discussed in Note 3 and Note 
4(a)) were dilutive and therefore included in the calculation, 
except for shares of Series F Preferred Stock which were 
repurchased in May 1997.

     For both the three months and nine months ended September 30, 
1997, the income effects of assuming conversion of dilutive 
preferred stock issuances were approximately $10,612,000 and 
$49,173,000, respectively. For the same periods, the share effects 
of assuming conversion of

                                  4
<PAGE>
dilutive preferred stock issuances were approximately 15,952,000 
and 27,953,000 shares, respectively.

3.  REDEEMABLE PREFERRED STOCK

     During August 1997, the Company exchanged its Series A 
Preferred Stock for Series H Preferred Stock. The Series A 
Preferred Stock was, and the Series H Preferred Stock is, owned by 
affiliates of Berkshire Hathaway, Inc. The provisions of the 
Series H Preferred Stock are substantially similar to those of the 
Series A Preferred Stock, with the following exceptions: The 
Series H Preferred Stock cannot be redeemed before March 15, 1998; 
the early redemption premium has been increased from $100 per 
share to $150 (as with the Series A Preferred Stock, the Series H 
Preferred Stock is mandatorily redeemable on August 7, 1999); and 
certain changes have been made to provisions related to sales of 
Series H Preferred Stock other than to US Airways Group. This 
exchange transaction facilitated the redemption of the Series B 
Preferred Stock (see Note 4(a)).

     On May 21, 1997, British Airways converted 28,059.364 shares 
of Series F Preferred Stock into 14,458,851 shares of Common 
Stock, which it then sold to third parties. On May 22, 1997, the 
Company repurchased the remaining outstanding shares of Series F 
Preferred Stock and all of the Series T Preferred Stock (both 
series were held exclusively by British Airways) for $126.2 
million (which included a premium over the stated amount of $5.2 
million for the shares of Series F Preferred Stock repurchased and 
$0.8 million for the Series T Preferred Stock). The Company's 
board of directors declared regular quarterly dividends on the 
Series F and Series T Preferred Stock prior to the conversion and 
repurchase transactions. As of May 22, 1997, the Company believes 
British Airways held no ownership interest in US Airways Group.

     During the first nine months of 1997, the Company paid 
dividends totaling $116.4 million on its Series A, Series H, 
Series F and Series T Preferred Stock (see Note 7 to the Company's 
Annual Report on Form 10-K for the year ended December 31, 1996 
for a description of each series, except for the Series H 
Preferred Stock which is discussed above), including payment of 
all dividends in arrears.

4.  STOCKHOLDERS' EQUITY

     (a)  SERIES B PREFERRED STOCK

     On April 17, 1997, the Company paid dividends of $46.6 
million on its publicly-held Series B Preferred Stock. With that 
payment, the Company had paid all dividends in arrears on its 
Series B Preferred Stock. The Company paid regular quarterly 
dividends of $4.7 million on its Series B Preferred Stock on May 
15, 1997 and August 15, 1997.

     During August 1997, the Company notified the holders of its 
Series B Preferred Stock that it would redeem all outstanding 
depositary shares representing Series B Preferred Stock on 
September 15, 1997 at $51.75 per depositary share plus accrued 
dividends of $0.3646 per depositary share. Because conversion was 
financially advantageous to the holders, all but approximately 
6,000 depositary shares were converted into Common Stock prior to 
the redemption date resulting in the issuance of approximately 
10.6 million shares of Common Stock.

     (b)  UNREALIZED GAIN ON AVAILABLE-FOR-SALE SECURITIES, NET OF
          INCOME TAX EFFECTS

     In accordance with Statement of Financial Accounting 
Standards No. 115, "Accounting for Certain Investments in Debt and 
Equity Securities" ("SFAS 115"), the Company recognizes an 
adjustment to Stockholders' Equity to reflect differences between

"available-for-sale" under SFAS 115) and their respective carrying 
values at each balance sheet date. Any adjustment is recognized 
net of estimated income taxes.

     (c)  ADJUSTMENT FOR MINIMUM PENSION LIABILITY, NET OF INCOME
          TAX EFFECTS

     In conjunction with the annual valuation of US Airways' 
defined benefit plans, the Company recorded an Adjustment for 
minimum pension liability as of September 30, 1997. The provisions 
of Statement of Financial Accounting Standards No. 87, "Employers' 
Accounting for Pensions," require the recognition of an additional 
minimum pension liability for each defined benefit plan for which 
the accumulated benefit obligation exceeds plan assets. This 
amount has been recognized by the Company as a liability with an 
offsetting intangible asset. Because the intangible asset 
recognized may not exceed the amount of unrecognized prior service 
cost on an individual plan basis, the balance is reported as a 
separate adjustment to Stockholders' Equity, net of income tax 
effects.

5.  BRITISH AIRWAYS INVESTMENT

     As discussed in Note 3, "Redeemable Preferred Stock," the 
Company believes that British Airways held no ownership interest 
in US Airways Group as of May 22, 1997. As of December 31, 1996, 
the preferred stock held by British Airways represented 
approximately 23% of the total voting interest in the Company.

6.  USAM INVESTMENTS

     Prior to the events described below, USAM Corp. ("USAM"), a 
wholly-owned subsidiary of US Airways, owned 11% of the Galileo 
International Partnership ("GIP"), approximately 11% of the 
Galileo Japan Partnership ("GJP") and approximately 21% of the 
Apollo Travel Services Partnership ("ATS"). The following is 
summarized financial information for these partnerships (combined, 
in millions):

  *USAM discontinued using the equity method of accounting for
   its investments in GIP and ATS on July 30, 1997 (see below).

     On July 30, 1997, Galileo International, Inc. ("Galileo") 
completed an initial public offering ("IPO") and used the 
proceeds, together with the proceeds of bank financing, to 
purchase ATS. Immediately preceding the IPO, GIP was merged with 
and into a wholly-owned limited liability company subsidiary of 
Galileo and USAM received shares in Galileo in the same proportion 
as its partnership interest in GIP. As part of the IPO, USAM sold 
some of its Galileo shares and its interest in Galileo was reduced 
from 11% to approximately 6.7%. USAM received proceeds of $62.2 
million and recognized a pre-tax gain of approximately $50 million 
from the sell-down of its interest in Galileo and received 
proceeds of $162.0 million and recognized a pre-tax gain of 
approximately $130 million in connection with the ATS sale.

     USAM applies the provisions of Statement of Financial 
Accounting Standards No. 115, "Accounting for Certain Investments 
in Debt and Equity Securities," to account for its remaining 
investment in Galileo, which is classified as available-for-sale.

                                  6
<PAGE>
     USAM received distributions from GIP, GJP and ATS of $12.7 
million, $0.2 million and $4.6 million, respectively, during the 
first nine months of 1997. USAM received distributions from GIP, 
GJP and ATS of $2.8 million, $0.1 million and $41.9 million 
(including a special distribution from ATS of $33.7 million during 
the second quarter of 1996), respectively, during the first nine 
months of 1996.

7.  NONRECURRING ITEMS

     During the second quarter of 1997, US Airways reversed $1.5 
million of previously accrued lease obligations upon subleasing an 
additional British Aerospace BAe-146-200 aircraft (recorded as a 
credit to Aircraft rent expense). 

     US Airways also recognized nonrecurring expenses totaling 
$28.3 million during the second quarter of 1997 related to 
efficiency measures announced during May 1997: $6.9 million 
recorded in Personnel costs related to estimated employee 
severance payments; $2.9 million recorded in Other rent and 
landing fees related primarily to the write-off of lease 
obligations at certain facilities to be abandoned (net of any 
anticipated sublease revenues); and $18.5 million recorded in 
Depreciation and amortization related primarily to the write-down 
of certain McDonnell Douglas DC-9-30 ("DC-9") aircraft to 
estimated fair value. The efficiency measures include grounding of 
22 excess aircraft, including five Fokker F28-4000 and 17 DC-9 
aircraft (all of the F28-4000 aircraft and eleven of the DC-9 
aircraft had been retired as of September 30, 1997), ending 
unprofitable jet service to nine cities and eliminating other 
routes that have not been profitable (completed during early 
September 1997) and closing a flight crew base (by February 1998), 
two reservations centers (October 1997) and three maintenance 
facilities (by December 1998).

     The Company recognized additional nonrecurring expenses 
totaling $72.3 million during the third quarter of 1997 including 
$59.3 million recorded in Depreciation and amortization resulting 
from US Airways' late-September 1997 decision to retire its 
remaining DC-9 aircraft over the next several years. The remaining 
nonrecurring expenses recognized during the third quarter of 1997, 
$11.3 million recorded in Depreciation and amortization and $1.7 
million recorded in Other rent and landing fees, include the 
write-down of certain equipment to be disposed of as a result of 
the May 1997 efficiency measures and certain other adjustments to 
the second quarter 1997 charges.

     In addition, as discussed in Note 6, "USAM Investments," USAM 
recognized a pre-tax gain of $179.6 million which resulted from 
its sale of certain investments.

8.  SUBSEQUENT EVENTS

     On October 31, 1997, US Airways' pilots ratified a new five 
year labor contract. The new contract includes, among other terms 
and conditions, no pre-determined guaranteed increases to hourly 
rates of pay, certain work rule changes and allowing US Airways to 
establish a low cost, low fare product. US Airways believes that 
this new contract will help it to reduce its unit operating costs, 
which are currently the highest of all major domestic air 
carriers.

     On October 31, 1997, the Company entered into agreements with 
AVSA, S.A.R.L. ("AVSA"), an affiliate of aircraft manufacturer 
Airbus Industrie G.I.E. ("Airbus"), and CFM International Inc. 
("CFMI") for the acquisition of up to 400 Airbus A320 family 
aircraft and accompanying jet engines. The A320 family aircraft 
are single-aisle "narrowbody" aircraft which include the Airbus 
A319, A320 and A321. 

     The Company has 124 aircraft on firm order, 116 aircraft 
subject to reconfirmation prior to scheduled delivery and options 
for 160 additional aircraft. Of the first 124 aircraft six are 
scheduled for delivery in 1998, 20 in 1999 and 98 in the years 
2000 through 2002. The Company anticipates

                                  7
<PAGE>
that the new Airbus aircraft will ultimately replace, at a 
minimum, US Airways' DC-9-30, MD-80 and B737-200 aircraft.

     The minimum determinable payments associated with the 
Company's agreements with AVSA and CFMI (including progress 
payments, payments at delivery, buyer-furnished equipment, spares, 
capitalized interest, penalty payments, cancellation fees and/or 
nonrefundable deposits) are currently estimated at $92 million 
during the fourth quarter of 1997, $261 million in 1998, $701 
million in 1999, $1.06 billion in 2000 and $212 million in 2001.

     As previously disclosed, US Airways has been in discussions 
with The Boeing Company ("Boeing") and Rolls Royce Plc. concerning 
certain agreements to purchase eight B757-200 aircraft and 40 
B737-Series aircraft. On September 11, 1997, Boeing filed suit 
against US Airways in state court in King County, Washington, 
alleging among other things, that US Airways had breached these 
aircraft purchase agreements. The lawsuit seeks, among other 
things, monetary damages of an unspecified amount. On October 31, 
1997, US Airways filed an answer and counterclaim to Boeing's 
complaint denying liability and seeking recovery from Boeing of 
approximately $45 million in equipment purchase deposits and past 
overcharges.

     US Airways intends to vigorously defend the Boeing lawsuit. 
US Airways cannot predict the outcome of the lawsuit or whether US 
Airways' financial condition or results of operations would be 
materially affected as a result of the lawsuit.

           NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                          (UNAUDITED)


1.  BASIS OF PRESENTATION

     The accompanying Condensed Consolidated Financial Statements 
include the accounts of US Airways, Inc. ("US Airways") and its 
wholly-owned subsidiary USAM Corp. ("USAM"). US Airways is a 
wholly-owned subsidiary of US Airways Group, Inc. ("US Airways 
Group").

     US Airways terminated its Airline Technical Services, LLC 
joint venture with a subsidiary of British Airways Plc. effective 
January 1997. No material charges resulted from its termination.

     Management believes that all adjustments necessary for a fair 
statement of results have been included in the Condensed 
Consolidated Financial Statements for the interim periods 
presented, which are unaudited. All significant intercompany 
accounts and transactions have been eliminated. The preparation of 
financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and 
liabilities and disclosure of contingent assets and liabilities at 
the date of the financial statements and the reported amounts of 
revenues and expenses during the reporting period. Actual results 
could differ from those estimates.

     Certain 1996 amounts have been reclassified to conform with 
1997 classifications.

     These interim period Condensed Consolidated Financial 
Statements should be read in conjunction with the Consolidated 
Financial Statements contained in US Airways' Annual Report on 
Form 10-K for the year ended December 31, 1996.

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

                                GENERAL

     Part I, Item 2 of this report should be read in conjunction 
with Part II, Item 7 of US Airways Group, Inc.'s ("US Airways 
Group" or the "Company") and US Airways, Inc.'s ("US Airways") 
Annual Report to the United States Securities and Exchange 
Commission ("SEC") on Form 10-K for the year ended December 31, 
1996. The information contained herein is not a comprehensive 
management overview and analysis of the financial condition and 
results of operations of the Company and US Airways, but rather 
updates disclosures made in the aforementioned filing.

     Certain information contained herein should be considered 
"forward-looking information" which is subject to a number of 
risks and uncertainties. The preparation of forward-looking 
information requires the use of estimates of future revenues, 
expenses, activity levels and economic and market conditions, many 
of which are outside the Company's control. Among the specific 
factors that could cause actual results to differ materially from 
those set forth in the forward-looking information are the 
following: economic conditions, labor costs, aviation fuel costs, 
competitive pressures from lower cost competition, weather 
conditions, government legislation, consumer perceptions of the 
Company's products, demand for air transportation in the markets 
in which the Company operates and other risks and uncertainties 
listed from time to time in the Company's reports to the SEC. 
Other factors and assumptions not identified above are also 
involved in the preparation of forward-looking information, and 
the failure of such other factors and assumptions to be realized 
may also cause actual results to differ materially from those 
discussed. The Company assumes no obligation to update such 
estimates to reflect actual results, changes in assumptions or 
changes in other factors affecting such estimates.

     Except where noted, the following discussion relates 
primarily to the financial condition, results of operations and 
future prospects of US Airways. US Airways is the Company's 
principal subsidiary, accounting for approximately 92% of the 
Company's operating revenues for the first nine months of 1997 (on 
a consolidated basis). US Airways' financial results include the 
financial results of its wholly-owned subsidiary USAM Corp. 
("USAM").

                         FINANCIAL OVERVIEW

     For the third quarter of 1997, the Company's operating 
revenues were $2.12 billion, operating income was $83.2 million, 
net income was $187.0 million and income per common share (or 
"EPS") was $2.04 on a primary basis and $1.82 on a fully diluted 
basis (the Company's Condensed Consolidated Statements of 
Operations are contained in Part I, Item 1A of this report. See 
Note 2 in Notes to Condensed Consolidated Financial Statements, 
which are also contained in Part I, Item 1A of this report, and 
Exhibit 11 to this report for additional information related to 
EPS). For the first nine months of 1997, operating revenues were 
$6.43 billion, operating income was $514.3 million, net income was 
$545.3 million and EPS was $6.48 on a primary basis and $5.18 on a 
fully diluted basis. The Company's financial results for the third 
quarter and first nine months of 1997 include pre-tax gains 
totaling $179.6 million which resulted from USAM's sale of certain 
investments (as discussed under "USAM Investments" below) as well 
as certain nonrecurring items. See "Results of Operations" below 
for additional information related to the Company's results of 
operations, including nonrecurring items.

               PILOTS RATIFY NEW LABOR CONTRACT
 
     On October 31, 1997, US Airways' pilots ratified a new five 
year labor contract. This new contract, along with the Company's 
agreements to acquire new aircraft and jet engines (see

                                  13

"Affirmation of Airbus Order" below) are of paramount importance 
to the Company's future, particularly with respect to ensuring 
competitiveness and long-term financial viability. 

Provisions of US Airways' new contract with its pilots include:

*  No pre-determined guaranteed increases to hourly rates of pay 
for "mainline" operations for existing aircraft types and new 
Airbus aircraft through the term of the contract. Reviews must be 
completed by January 1 of the years 2001, 2002 and 2003 to 
determine what adjustments (increases or decreases), if any, must 
be made to rates of pay and/or work rules so that US Airways' 
pilot costs (pay and productivity) are at parity plus 1% as 
compared to a weighted average of mainline pilot costs at American 
Airlines, Inc. ("American"), Delta Air Lines, Inc. ("Delta"), 
Northwest Airlines, Inc. ("Northwest") and United Airlines, Inc. 
("United"). At the option of the pilots, an additional "Interim 
Review" may be undertaken for completion by January 1, 1999. 
*  Allowing US Airways to establish a "low cost, low fare" product 
to compete with Southwest Airlines, Inc. ("Southwest"), Delta's 
Delta Express product, AirTran Airlines Inc. ("AirTran," whose 
operations now include those of the former ValuJet Airlines, Inc.) 
and other such competitors in certain markets and under certain 
conditions. US Airways' low cost, low fare product can begin 
service with up to 54 aircraft with the flexibility, under certain 
circumstances, to expand its operations up to 25% of US Airways' 
total system block hours. Pay rates for pilots on US Airways' low 
cost, low fare product will be comparable to those of Southwest's 
pilots (with pay protection for mainline pilots involuntarily 
displaced to US Airways' low cost, low fare product ending when 
such pilots have the ability to return to mainline operations).
*  Work rule changes including reductions in sick leave and 
vacation liabilities which are estimated to result in significant 
annual savings when fully implemented.
*  Allowing the Company's commuter air carriers to operate up to 
the greater of 35 regional jet aircraft or the equivalent of 9% of 
US Airways' operating fleet, once all pilots are recalled from 
furlough.
*  A commitment to grow at an annual rate the greater of 2.5% (as 
measured by system block hours) or 20% above the average block 
hour growth rate of American, Delta, Northwest and United subject 
to certain deferral rights and force majeure provisions.
*  Lump sum payments to pilots equal to 1% of annual salary for 
the calendar years 1999, 2001 and 2002,  payable in the subsequent 
calendar year.
*  11.5 million options to purchase US Airways Group Common Stock, 
to be issued ratably to pilots over the five-year life of the 
contract, with exercise prices established based on the fair 
market value of the Company's Common Stock over a time period 
proceeding each grant date.
*  An early retirement program for up to 325 pilots and the recall 
from furlough by December 15, 1997 of 100 pilots furloughed in 
1997, as well as offering recall by December 31, 2001 of 283 
additional pilots furloughed prior to 1997.
*  A requirement for US Airways to operate certain levels of 
transoceanic block hours before increasing international code-
sharing.
*  Certain change of control protections, including cash payments 
to pilots of up to $250 million under certain circumstances if US 
Airways is acquired and is not the surviving entity and the 
pilots' labor contract is adversely affected as a result of the 
acquisition.
*  Certain job security provisions, including a "no furlough" 
clause for pilots on the seniority list on the effective date of 
the agreement.

     US Airways currently estimates that the early retirement 
program will result in a nonrecurring charge of approximately $115 
million in accordance with the provisions of Financial Accounting 
Standards Board ("FASB") Statement of Financial Accounting 
Standards ("SFAS") No. 88, "Employers' Accounting for Settlements 
and Curtailments of Defined Benefit Pension Plans and for 
Termination Benefits" ("SFAS 88"). This charge would be recognized 
in Personnel costs during the second quarter of 1998, when the 
number of pilots who opt for early retirement is expected to be 
established. US Airways expects to realize significant net long-
term savings in both wages and 

                                  14
<PAGE>
benefits expenses as a result of the early retirement program. US 
Airways will recognize expenses for the lump sum payments, 
approximately $20 million, in Personnel costs ratably through 
December 31, 2002. Any Personnel cost expenses associated with the 
stock options granted under the new contract would be recognized 
over the vesting period of the grant and be dependent upon the 
exercise price of each grant.

     US Airways continues negotiations with the International 
Association of Machinists and Aerospace Workers ("IAM"), which 
represents US Airways' mechanical and related personnel, and the 
Association of Flight Attendants ("AFA"), which represents US 
Airways' flight attendants. US Airways has opened negotiations 
with the IAM for fleet service employees and will soon begin 
negotiations with the Communication Workers of America ("CWA") for 
passenger service employees with respect to initial contracts for 
both employee groups (see also "Other Information" below).

                   AFFIRMATION OF AIRBUS ORDER

     On October 31, 1997, the Company entered into agreements with 
AVSA, S.A.R.L. ("AVSA"), an affiliate of aircraft manufacturer 
Airbus Industrie G.I.E. ("Airbus"), and CFM International Inc. 
("CFMI") for the acquisition of up to 400 Airbus A320 family 
aircraft and accompanying jet engines. The A320 family aircraft 
are single-aisle "narrowbody" aircraft which include the Airbus 
A319, A320 and A321. As part of the agreement with CFMI, GE Engine 
Services, Inc. will provide maintenance for the engines under a 
20-year agreement.

     The Company has 124 aircraft on firm order, 116 aircraft 
subject to reconfirmation prior to scheduled delivery and options 
for 160 additional aircraft. Of the first 124 aircraft six are 
scheduled for delivery in 1998, 20 in 1999 and 98 in the years 
2000 through 2002. The Company anticipates that the new Airbus 
aircraft will ultimately replace, at a minimum, US Airways' DC-9-
30, MD-80 and B737-200 aircraft. See related information under 
"Liquidity and Capital Resources" below.

     The Airbus aircraft are more efficient, less costly to 
maintain and provide certain customer service benefits over the 
aircraft they are intended to replace. However, certain operating 
costs such as Depreciation and amortization and Aircraft rent are 
likely to increase in conjunction with the higher ownership and/or 
rental costs associated with the new aircraft. In addition, US 
Airways may be required to recognize an "impairment charge" 
related to aircraft to be retired, as defined in FASB SFAS No. 
121, "Accounting for the Impairment of Long-Lived Assets and Long-
Lived Assets to Be Disposed Of" ("SFAS 121"). US Airways is 
currently unable to determine the amount of such a charge, if any, 
because certain information required for the analysis is currently 
undetermined (e.g., aircraft retirement dates). See also "Results 
of Operations: Nonrecurring items" below for additional 
information regarding SFAS 121.

            UPDATE ON US AIRWAYS' COMPETITIVE POSITION

     US Airways' primary competitive threat continues to be the 
growth of low cost, low fare competition in its primary operating 
region, the Eastern United States. US Airways' estimated 
origin/destination passenger overlap with low cost, low fare 
competition was approximately 49% of its passenger base as of 
October 1997 as compared to approximately 50% as of April 1997. 
This slight decrease is due to schedule changes by US Airways, 
which eliminated some affected markets (see "Efficiency Measures" 
below), offset by continued growth of low cost, low fare 
competition in the Eastern U.S.

     During October 1997, the U.S. Department of Transportation 
("DOT") awarded several low cost, low fare air carriers takeoff 
and landing rights ("slots") at New York's LaGuardia Airport 
("LaGuardia") and at Chicago's O'Hare International Airport. The 
DOT awarded the slots as part of new policies designed to increase 
competition at certain high-traffic domestic airports.

                                  15
<PAGE>
Previously, slots at such airports (which also include New York's 
John F. Kennedy International Airport and Washington National 
Airport ("National")) were restricted by government regulation and 
were only available through purchase or lease from another air 
carrier. US Airways has a considerable number of slots at such 
airports, primarily at LaGuardia and National. The recent awards 
were minimal and are not expected to have a material adverse 
impact on the Company's results of operations and financial 
condition. 

     There are several proposals before Congress which would  
address service to small and medium-size airports. Most notable is 
a bill which would, among other things, confiscate slots from the 
major air carriers at the four high-density airports mentioned in 
the preceding paragraph and auction them off to new entrant air 
carriers. US Airways has testified in opposition to such a plan. 
Adoption of such a plan could force a reduction in US Airways' 
flights from LaGuardia and National to certain communities on the 
East Coast and could have an adverse effect on the Company's 
results of operations and financial position.

    Direct competition with low cost, low fare air carriers or 
operations has typically resulted in the dilution of yield 
realized by the Company's airline subsidiaries, depending on the 
number of markets affected. In addition, US Airways continues to 
have the highest unit operating cost (operating cost per ASM or 
"cost per ASM") of all domestic air carriers. US Airways' cost per 
ASM was 12.27 cents for the third quarter of 1997. By contrast, 
Southwest and AirTran reported unit operating costs for the same 
period of 7.36 cents and 8.11 cents, respectively. Delta Express' 
unit operating cost is purported to be approximately 7.50 cents. 
However, as discussed above, US Airways' new labor contract with 
its pilots establishes the groundwork for US Airways to launch a 
cost competitive answer to low cost, low fare competition. US 
Airways' new product, which may include a new brand identity and 
style of service, is expected to be launched in early 1998. 
Although a route system for the new product is currently being 
developed, Baltimore/Washington International Airport ("BWI") is 
expected to play a major role. 

     US Airways continues to evaluate other measures through which 
it can improve its competitiveness and fulfill its strategic 
objectives. One of the Company's primary strategic objectives is 
to expand the breadth of US Airways' operations on an 
international scale and establish US Airways as a global airline 
of choice. US Airways has recently undertaken steps to realize 
this objective including announcing plans to build a new 
international terminal and a new US Airways Express terminal at 
Philadelphia International Airport. Other actions may include 
purchasing the US Airways Shuttle (see "US Airways Shuttle" below) 
and creating a Midwestern hub. The Company is examining 
alternatives for widebody aircraft to support its growing 
international operations and is currently discussing the 
acquisition of widebody aircraft with both Airbus and Boeing.

     US Airways' added a second daily non-stop flight between 
Philadelphia and Paris on June 14, 1997 and will begin twice-daily 
service between Philadelphia and London's Gatwick Airport on April 
1, 1998. US Airways has filed with the DOT to serve London through 
Gatwick from Boston, Charlotte and Pittsburgh with the intent of 
transferring Gatwick operations to London's Heathrow Airport 
("Heathrow") at the earliest opportunity. Service at Heathrow is 
currently restricted by the bilateral aviation agreement between 
the U.S. and the United Kingdom. US Airways has also filed with 
the DOT and French authorities to serve Paris through Charles de 
Gaulle Airport from Pittsburgh and is currently seeking the proper 
authorizations to initiate service between Philadelphia and Milan. 
During October 1997, US Airways discontinued service between 
Boston and Frankfurt.

                      EFFICIENCY MEASURES

     During May 1997, US Airways announced certain "efficiency 
measures" including: Retiring 22 aircraft from its operating 
fleet, including the last five Fokker F28-4000 ("F28-4000") 
aircraft and

                                  16
<PAGE>
17 older DC-9 aircraft (all of the F28-4000 aircraft and eleven of 
the DC-9 aircraft had been retired as of September 30, 1997); 
ending unprofitable service to nine cities and eliminating other 
routes that have not been profitable (completed during early 
September 1997); reducing capacity (ASMs) by approximately 6.5% by 
Summer 1998; and closing a flight crew base (by February 1998), 
two reservations centers (October 1997) and three maintenance 
facilities (by December 1998).

     The Company recognized nonrecurring charges during the second 
quarter of 1997 as a result of these actions. In late September 
1997, US Airways decided to retire its remaining DC-9 aircraft 
earlier than previously planned resulting in an additional 
nonrecurring charge (nonrecurring charges are discussed under 
"Results of Operations: Nonrecurring items," below). Excluding any 
SFAS 121 charges (see "Affirmation of Airbus Order" above), US 
Airways anticipates that deliveries of new Airbus aircraft will 
mitigate the effects of DC-9 retirements on its financial results 
and capacity.

     The Company has been working closely with union leaders and 
employee groups to minimize to the greatest degree possible the 
impact of changes in operations on affected employees. The Company 
expects these efficiency measures will ultimately result in the 
furlough of approximately 850 US Airways employees. See "Update on 
US Airways' Competitive Position" for information related to US 
Airways' strategic direction.

     US Airways moved a majority of its international operations 
at BWI to Philadelphia effective June 15, 1997. These schedule 
adjustments were made to further enhance the efficiency of US 
Airways' route network and take advantage of the traffic base and 
connection opportunities provided by US Airways' facilities at 
Philadelphia, US Airways' primary international gateway. These 
schedule adjustments resulted in the elimination of approximately 
240 full-time and part-time customer service and maintenance 
positions at BWI. However, as mentioned above, BWI is expected to 
play a major role in the launch of US Airways' new low cost 
operation.

    RESUMPTION OF REGULAR DIVIDEND PAYMENTS ON PREFERRED STOCK,
 BRITISH AIRWAYS' DIVESTITURE AND CALL OF SERIES B PREFERRED STOCK

     On March 26, 1997, the Company paid dividends totaling $34.8 
million to the holders of its Series A, Series F and Series T 
Preferred Stock and the Company's board of directors declared 
dividends of $46.6 million on the Company's Series B Preferred 
Stock (see Note 7 and Note 8 to the Company's Annual Report on 
Form 10-K for the year ended December 31, 1996 for a description 
of each of the Company's preferred stock issuances). After payment 
of the Series B Preferred Stock dividends during May 1997, the 
Company had paid all dividends in arrears (including penalty 
dividends on the deferred dividends) and had resumed regular 
quarterly dividend payments on all of its outstanding preferred 
stock issuances. 

     During May 1997, British Airways Plc. ("British Airways") 
converted 28,059.364 shares of Series F Preferred Stock into 
14,458,851 shares of Common Stock, which it then sold to third 
parties. Also during May 1997, the Company repurchased the 
remaining shares of Series F Preferred Stock and all of the Series 
T Preferred Stock (both series were held exclusively by British 
Airways). The Company's board of directors declared regular 
quarterly dividends on the Series F and Series T Preferred Stock 
prior to the conversion and repurchase transactions. After the 
conversion and repurchase transactions, the Company believes that 
British Airways held no ownership interest in US Airways Group 
(see also "Liquidity and Capital Resources" below).

     During August 1997, the Company exchanged its Series A 
Preferred Stock for Series H Cumulative Convertible Preferred 
Stock ("Series H Preferred Stock"). The Series A Preferred Stock 
was, and the Series H Preferred Stock is, owned by affiliates of 
Berkshire Hathaway, Inc. ("Berkshire Hathaway"). The provisions of 
the Series H Preferred Stock are substantially similar to those of 
the Series A Preferred Stock (see Note 3 to the Company's 
Condensed Consolidated

                                  17
<PAGE>
Financial Statements for additional information). The exchange 
transaction facilitated the redemption of the Series B Preferred 
Stock (as discussed below). 

     On August 18, 1997, the Company notified the holders of its 
Series B Preferred Stock that it would redeem all outstanding 
depositary shares representing Series B Preferred Stock on 
September 15, 1997 at $51.75 per share plus accrued dividends of 
$0.3646 per share. Because conversion was financially advantageous 
to the holders, all but approximately 6,000 depositary shares were 
converted into Common Stock prior to the redemption date resulting 
in the issuance of approximately 10.6 million shares of Common 
Stock (see also "Liquidity and Capital Resources" below).

     With the retirement of the Series B, Series F and Series T 
Preferred Stock, the Company's annual preferred stock dividend 
burden has been reduced by approximately $46 million. Future 
dividend payments by the Company are primarily dependent on the 
Company's future financial performance and decisions by its board 
of directors. There can be no assurance that the Company's current 
positive financial performance will continue or if the Company 
will be able to maintain a capital surplus position based on its 
balance sheet, as defined under the laws of the State of Delaware.

     Sections 382 and 383 of the Internal Revenue Code and the 
regulations thereunder impose limitations on the utilization of 
net operating loss and credit carryforwards if a corporation has 
had a "change of control" as defined therein. Generally, a change 
of control occurs if the corporation experiences more than a 50% 
ownership change over a rolling three year testing period. In 
general, if a corporation has a change of control, the amount of 
loss carryforwards and credits that can be used in any subsequent 
year are limited to an amount equal to the product of the value of 
the corporation's stock immediately prior to the change multiplied 
by the "long-term tax exempt rate," as defined by the U.S. 
Internal Revenue Service. The Company does not believe it 
experienced a change of control before the British Airways and 
Series B Preferred Stock transactions discussed above, nor does it 
believe that those transactions caused a change of control. As of 
December 31, 1996 the Company had approximately $1.5 billion 
unused net operating loss carryforward, $375 million alternative 
net operating loss carryforward, $50 million of investment tax 
credits, and $33 million alternative minimum tax credits. The 
Company expects to use a significant portion of these 
carryforwards during 1997. The Company will also review whether 
and to what extent it is appropriate to continue to apply a 
valuation allowance to its deferred tax assets in accordance with 
SFAS No. 109, "Accounting for Income Taxes," and any change in the 
valuation allowance could differ materially from that recorded as 
of December 31, 1996.

                      USAM INVESTMENTS
 
     On July 30, 1997, Galileo International, Inc. ("Galileo") 
completed an initial public offering ("IPO") and used the 
proceeds, together with the proceeds of bank financing, to 
purchase Apollo Travel Services Partnership ("ATS"). USAM owned 
approximately 21% of ATS. Immediately preceding the IPO, Galileo 
International Partnership ("GIP") was merged with and into a 
wholly-owned limited liability company subsidiary of Galileo and 
USAM received shares in Galileo in the same proportion as its 
partnership interest in GIP. As part of the IPO, USAM sold some of 
its Galileo shares and its interest in Galileo was reduced from 
11% to approximately 6.7%. USAM received proceeds of $62.2 million 
and recognized a pre-tax gain of approximately $50 million from 
the sell-down of its interest in Galileo and received proceeds of 
$162.0 million and recognized a pre-tax gain of approximately $130 
million in connection with the ATS sale.

     USAM applies the provisions of SFAS No. 115, "Accounting for 
Certain Investments in Debt and Equity Securities," to account for 
its remaining investment in Galileo. The resulting adjustment to 
Stockholders' Equity to reflect the increase in the fair value of 
USAM's Galileo investment over its carrying cost is reflected in 
the Company's balance sheet line item Unrealized gain on 
available-for-

                                18
<PAGE>
sale securities, net of income tax effects (see also Note 4(c) to 
the Company's Condensed Consolidated Financial Statements).   

                          US AIRWAYS SHUTTLE

     On March 31, 1997, the Company exercised its right to 
commence a procedure to value Shuttle, Inc. ("Shuttle"), the owner 
of the US Airways Shuttle, in accordance with the agreement 
between the Company, lenders to Shuttle and Shuttle's stockholders 
(the "Valuation Procedure"). Culminating the Valuation Procedure, 
an independent appraiser has provided to the Company, lenders to 
Shuttle and Shuttle's stockholders its determination of Shuttle's 
value. The Company has until November 22, 1997 to commit to 
purchase Shuttle at this amount. However, if the Company declines 
to purchase Shuttle at this amount, it will continue to have a 
right of first refusal with respect to any other agreement to 
purchase the assets or capital stock of Shuttle. Any decision by 
the Company to purchase Shuttle either through the Valuation 
Procedure or the right of first refusal will be made based on 
prices and related business considerations.

     The US Airways Shuttle currently operates a fleet of 12 
Boeing 727-200 aircraft and provides high frequency service from 
New York to Boston and Washington, DC.

                     OTHER INFORMATION

     US Airways has signed a letter of intent with The SABRE 
Group, Inc. ("Sabre") to manage US Airways' information 
technology. The agreement, which would span 25 years, envisions 
Sabre purchasing US Airways' computer equipment and proprietary 
software. In return, US Airways would have access to Sabre 
technology and expertise in areas such as reservations, passenger 
check-in, aircraft and crew scheduling, yield management and 
electronic ticketing. Approximately 875 US Airways information 
services employees would be offered jobs with Sabre or otherwise 
leave US Airways' employment. Sabre would also be responsible for 
ensuring that US Airways' information systems are year 2000 
compliant. The proposed arrangement would result in reduced 
Personnel costs and higher Other operating expenses. US Airways 
expects to finalize this agreement by the end of 1997.

     During October 1997, electronic ticketing sales for travel on 
US Airways and its regional affiliates reached 20% of all ticket 
sales. Also during October 1997, US Airways expanded electronic 
ticketing to include travel between the U.S. and Canada. The 
Company, whose "E-ticket" program was launched in April 1996, 
believes that electronic ticketing reduces distribution costs.

     On September 29, 1997, US Airways' passenger service 
employees, approximately 9,200 employees, voted for representation 
by CWA. This election was a re-run election mandated by the 
National Mediation Board ("NMB"). In January 1997, US Airways 
passenger service employees voted against unionization, but the 
NMB subsequently ordered that a new representation election be 
held for these employees because of alleged interference by US 
Airways with the election process. US Airways has filed an action 
challenging this order in federal court.

     On September 24, 1997, US Airways announced that it has 
reduced the rates for base commissions paid to travel agencies 
from 10% of ticket price to 8% on all domestic and international 
tickets issued by travel agents in U.S., Puerto Rico, the U.S. 
Virgin Islands and Canada. US Airways' existing maximum payment of 
$25 one-way and $50 round-trip for tickets purchased in the U.S. 
and Puerto Rico for travel in and between the U.S., Puerto Rico 
the U.S. Virgin Islands and Canada remains unchanged.

     On August 5, 1997, President Clinton signed legislation 
extending federal excise taxes on air transportation ("ticket 
tax") from October 1, 1997 through September 30, 2007. In 
addition, effective October 1, 1997, the legislation reduced the 
domestic ticket tax from the prior level of

                                  19
<PAGE>
10% of fare to 9.0% (decreasing to 8.0% on October 1, 1998 and to 
7.5% on October 1, 1999), added a new segment tax of $1.00 (which 
increases to $3.00 by the year 2002), changed the current $6.00 
international departure tax to $12.00 and added a $12.00 
international arrival tax. The legislation also added a new 7.5% 
tax effective October 1, 1997 on certain purchases of frequent 
traveler program miles from domestic air carriers. The Company 
does not believe that the new ticket tax structure will have a 
material adverse effect on its liquidity, financial condition or 
results of operations.

     The Federal Aviation Administration has proposed new 
regulations that would require certain commercial passenger 
aircraft to have cargo hold fire detection/suppression systems. 
The proposed regulations, subject to DOT approval, would affect US 
Airways' Boeing 737-Series, DC-9 and MD-80 aircraft (the other 
aircraft types in US Airways' operating fleet already have such 
systems). US Airways estimates that compliance with the proposal, 
as currently drafted, would cost approximately $22 million over 
the recommended three-year phase-in period. The Company is unable 
to predict whether or when the proposed regulations will be 
adopted or if any such regulations, if adopted, would differ 
materially from the current proposed regulations.

RESULTS OF OPERATIONS

     The following section includes information related to changes 
in certain line items in the Company's Condensed Consolidated 
Statements of Operations and in select US Airways operating and 
financial statistics. Except where noted, statistics referred to 
below in the comparisons of financial results are for scheduled 
service only.

            THREE MONTH PERIOD ENDED SEPTEMBER 30, 1997
                         COMPARED WITH THE
           THREE MONTH PERIOD ENDED SEPTEMBER 30, 1996

Operating Revenues (see also "Select US Airways Operating and 
Financial Statistics" below):

Passenger Transportation-US Airways' Passenger transportation 
revenues increased $28.5 million, or 1.6%, as the result of a 7.2% 
increase in revenue passenger miles ("RPMs") offset by the effects 
of a 5.2% decrease in yield. The Company estimates that inclement 
weather (hurricanes) during the third quarter of 1996 adversely 
affected Passenger transportation revenues by approximately $10 
million.

Cargo and Freight-Increased due primarily to increased volume, 
including the effects of the August 1997 labor strike at United 
Parcel Service of America, Inc.

Other Operating Revenues-The largest factor contributing to the 
increase is higher revenues from partners in US Airways' Dividend 
Miles program. Changes in other components of Other operating 
revenues are largely offset by correlating changes in operating 
expenses, primarily those recorded as Other, net. US Airways' 
results include certain transactions with related parties that are 
eliminated at the US Airways Group level.

     US Airways' Operating Revenues include the line item "US 
Airways Express transportation revenues." Effective October 1, 
1996, US Airways began purchasing all of the capacity (ASMs) 
generated by the Company's three wholly-owned regional air 
carriers and, concurrently, recognizing the passenger 
transportation revenues that result from passengers being carried 
by these companies. The rate per ASM that US Airways pays is based 
on estimates of the costs incurred to produce the capacity. The 
program is designed to reflect the reality of US Airways' 
relationship with the Company's regional airline subsidiaries-US 
Airways controls the markets these air carriers operate in, the 
marketing programs and the fares charged. US Airways' revenues 
from this program

                                  20
<PAGE>
are reclassified to Passenger transportation revenues and the 
related expenses eliminated during the consolidation of the 
Company's results of operations.

Operating Expenses (see also "Pilots Ratify New Labor Contract" 
and "Affirmation of Airbus Order" above):

Nonrecurring Items-The Company recognized nonrecurring items 
during the second and third quarters of 1997. The table below 
shows where these nonrecurring items were recorded in the 
Company's Condensed Consolidated Statements of Operations (dollars 
in millions; brackets indicate an expense).

     The second quarter charges relate primarily to the efficiency 
measures announced during May 1997, as discussed above under 
"Efficiency Measures." The second quarter charges also include a 
$1.5 million credit to Aircraft rent upon US Airways' subleasing 
an additional British Aerospace BAe-146-200 ("BAe-146") aircraft. 
The $2.9 million charge to Other rent and landing fees reflects 
the accrual of lease obligations at certain facilities 
abandoned/to be abandoned (net of any anticipated sublease 
revenues) as the result of the May 1997 efficiency measures; the 
$1.7 million charge to Other rent and landing fees recognized 
during third quarter 1997 is an adjustment of the second quarter 
facilities-related charge. 

     A majority of the Depreciation and amortization charges in 
both quarters stem from analyses performed in accordance with the 
provisions of SFAS 121. In general, SFAS 121 requires an 
impairment charge to be recognized when the net undiscounted 
future cash flows from an asset's use (including any anticipated 
proceeds from disposition) are less than the asset's current book 
value and the asset's current book value exceeds its fair value. 
The impairment charge reflects writing-down the assets to fair 
value. $18.1 million of the second quarter charge is an impairment 
charge associated with retiring 17 DC-9 aircraft as the result of 
the May 1997 efficiency measures and $59.3 million of the third 
quarter charge is an impairment charge resulting from US Airways' 
late-September 1997 decision to retire its remaining DC-9 aircraft 
over the next several years. US Airways has suspended its DC-9 
"hush-kit" program in conjunction with its decision to retire this 
fleet-type. As of September 30, 1997, US Airways' operating fleet 
included 50 owned DC-9s, including 27 of which were hush-kitted. 
The remaining components of the Depreciation and amortization 
charge in both quarters relate to the May 1997 efficiency 
measures. The second quarter charge relates primarily to 
facilities abandoned/to be abandoned as a result of the May 1997 
efficiency measures and the third quarter charge includes the 
write-down of certain equipment to be disposed of as a result of 
the May 1997 efficiency measures and certain other adjustments to 
the second quarter charges.

     Gains on sales of interests in affiliates resulted from 
USAM's sale of certain investments, as discussed above under "USAM 
Investments."

     During the second quarter of 1996, US Airways recognized two 
nonrecurring items related to subleasing eleven BAe-146 aircraft. 
A credit of $22.5 million, a reversal of previously accrued lease 
obligations, was recorded in Aircraft rent and a credit of $7.0 
million, a reversal of previously accrued lease return provisions, 
was recognized in Aircraft maintenance. 

Personnel Costs-Excluding nonrecurring items (see above), 
Personnel costs decreased $53.5 million. The Company recognized 
profit sharing expenses associated with US Airways' 1992 Salary 
Reduction Program of $41.1 million during third quarter 1996 (no 
such expenses were incurred during third quarter 1997). In 
addition, defined benefit pension and postretirement benefit 
expenses decreased due primarily to higher interest rates 
(discount factors) used for 1997 calculations. See related 
information under "Other Information." 

Aviation Fuel-Decreased as a result of an 8.1% decrease in US 
Airways' average cost of fuel per gallon partially offset by a 
1.8% increase in gallons of aviation fuel consumed. Effective for 
1997, the Company classifies fuel taxes as an element of Aviation 
fuel expense. These expenses were previously an element of the 
operating expense Other, net (prior period results have been 
reclassified for comparability purposes).

Commissions-See "Other Information" above related to recent 
changes in US Airways' commissions rate structure.

Aircraft Rent-Expenses increased due primarily to a rent expense 
adjustment of $9.6 million related to certain F28-4000 aircraft 
recognized during third quarter 1997.

Other Rent and Landing Fees-Excluding the effects of the 
nonrecurring items (see above), increased $8.7 million due 
primarily to out-of-period adjustments of $4.4 million and the 
timing of when certain facility rent credits were received period-
over-period.

Aircraft Maintenance-Increased due to two "unusual" charges 
recognized during third quarter 1997: $14.5 million related to 
unserviceable (scrapped) JT8D engine parts, and; $10.0 million in 
adjustments related to other spare parts. In addition, US Airways 
continues to experience increases in the cost of certain JT8D jet 
engine parts. Timing factors, primarily related to the timing and 
extent of engine overhauls, are the largest factor with respect to 
the remaining quarter-over-quarter variance. US Airways is 
realizing savings from the "power-by-the-hour" maintenance 
contract for its CFM-56 and CF-6 jet engines which began during 
the fourth quarter of 1996.

Depreciation and Amortization-Increased $7.0 million if 
nonrecurring items (see above) are excluded.

     US Airways' Operating Expenses include the line item "US 
Airways Express capacity purchases." These expenses, which are 
eliminated during the consolidation of the Company's results of 
operations, are discussed under Operating Revenues above.

Other Income (Expense):

Equity in Earnings of Affiliates-USAM discontinued applying the 
equity method of accounting to certain of its investments. See 
"USAM Investments" above for related information.

Gain on sales of interests in affiliates-See "USAM Investments" 
above.

                                  22
<PAGE>
Other, Net-Third quarter 1996 activity included losses totaling 
$10.5 million related to US Airways' sale of four DC-9 aircraft 
and its only owned BAe-146 aircraft and $9.8 million related to US 
Airways' settlement of litigation involving travel agencies.

Provision for Income Taxes-Increased due primarily to increased 
pre-tax income and an increase in the Company's effective tax rate 
as a result of the Company's projected utilization of all 
remaining alternative minimum tax net operating loss carryforwards 
during 1997. See also "Resumption of Regular Dividend Payments on 
Preferred Stock, British Airways' Divestiture and Call of Series B 
Preferred Stock" above for related information.

Income per Common Share-During the third quarter of 1997, most of 
the Series B Preferred Stock was converted into 10.6 million 
shares of Common Stock. On a weighted average basis, this 
transaction had the effect of increasing common shares outstanding 
by approximately 3.9 million shares for the third quarter of 1997 
(see also "Supplemental Information" below).

Supplemental Information-In June 1997, the FASB adopted SFAS No. 
130, "Reporting Comprehensive Income," ("SFAS 130") and SFAS No. 
131, "Disclosures About Segments of an Enterprise and Related 
Information" ("SFAS 131"). SFAS 130 establishes standards for the 
reporting and presentation of comprehensive income and its 
components in financial statements. SFAS 131 establishes standards 
for defining operating segments and the reporting of certain 
information regarding operating segments. The Company believes 
that neither SFAS 130 nor SFAS 131 will have an effect on the 
Company's liquidity, financial condition or results of operations 
as both standards are informational only. If the Company 
determines that it has a reporting obligation under either new 
standard, the necessary information will be disclosed as part of 
the Company's financial reporting in the appropriate period.

In February 1997, the FASB adopted SFAS No. 128, "Earnings per 
Share" ("SFAS 128"). This statement specifies new computation, 
presentation and disclosure requirements for reporting income per 
common share. The provisions of SFAS 128 preclude the Company from 
implementing the new standard prior to December 31, 1997. The 
Company believes that the implementation of SFAS 128 will not have 
a material impact on its future income per common share 
disclosures or on prior period income per common share amounts, 
which must be restated to conform with the provisions of SFAS 128.

              NINE MONTH PERIOD ENDED SEPTEMBER 30, 1996

Operating Revenues (see also "Select US Airways Operating and 
Financial Statistics" below):

Passenger Transportation-US Airways' Passenger transportation 
revenues increased $284.2 million, or 5.6%, as the result of a 
9.8% increase in RPMs offset by the effects of a 3.9% decrease in 
yield. The Company estimates that severe winter weather within the 
Eastern U.S. and the partial Federal Government shutdown adversely 
affected first quarter 1996 revenues by approximately $55 million. 
Inclement weather (hurricanes) during the third quarter of 1996 is 
believed to have negatively affected Passenger transportation 
revenues by approximately $10 million. 

Cargo and Freight-Increased primarily due to volume factors.

Other Operating Revenues-The largest factor contributing to the 
increase is higher revenues from partners in US Airways' Dividend 
Miles program and from reservation rebooking fees offset by 
decreased wet lease revenues. Wet lease revenues decreased $12.6 
million because these arrangements with British Airways ended 
during May 1996. Changes in other components of Other operating 
revenues are largely offset by correlating changes in related 
operating expenses, primarily

                                  23
<PAGE>
those recorded as Other operating expenses, net. US Airways' 
results include certain transactions with related parties that are 
eliminated at the US Airways Group level.

US Airways' Operating Revenues include the line item "US Airways 
Express transportation revenues." This activity is discussed in 
the quarter-over-quarter comparison above.

Operating Expenses (see also "Pilots Ratify New Labor Contract" 
and "Affirmation of Airbus Order" above):

Nonrecurring Items-The Company's Operating Expenses for both 1997 
and 1996 include the nonrecurring items discussed in the quarter-
over-quarter comparison of results of operations.

Personnel Costs-Decreased $52.4 million if nonrecurring items (see 
above) are excluded. The Company recognized profit sharing 
expenses associated with US Airways' 1992 Salary Reduction Program 
of $82.4 million during the first nine months of 1996 (no such 
expenses during 1997). Expenses associated with stock appreciation 
rights ("SARs") were $28.9 million during the first nine months of 
1997 (no such expenses during the first nine months of 1996). In 
addition, defined benefit pension and postretirement benefits 
expenses decreased due primarily to higher interest rates 
(discount factors) used for 1997 calculations.

Aviation Fuel-Primarily volume factors; US Airways' average cost 
of aviation fuel per gallon increased 0.8%.

Aircraft Rent-Excluding the effects of the nonrecurring items (see 
above), costs increased due primarily to rent expense adjustments 
totaling $16.8 million recorded during 1997 related to certain  
F28-4000 aircraft.

Aircraft Maintenance-As discussed in the quarter-over-quarter 
comparison above, certain unusual charges were recognized during 
the third quarter of 1997. Timing factors and an increase in the 
cost of certain JT8D jet engine parts also contributed to more 
than offsetting savings US Airways is realizing from the "power-
by-the-hour" maintenance contract covering its CFM-56 and CF-6 jet 
engines. 1996 activity also included a nonrecurring expense credit 
(see above).

Depreciation and Amortization-Relatively unchanged if nonrecurring 
items (see above) are excluded.

Other Operating Expenses, Net-Wet lease expenses decreased $12.6 
million (see also Other Operating Revenues above). This decrease 
was more than offset by increases in certain sales and traffic-
related expenses (most notably, credit card expenses).

     US Airways' Operating Expenses include the line item "US 
Airways Express capacity purchases." These expenses, which are 
eliminated during the consolidation of the Company's results of 
operations, are discussed under Operating Revenues above.

Other Income (Expense):

Equity in Earnings of Affiliates/Gains on Sales of Interests in 
Affiliates-See quarter-over-quarter comparison above.

Other, Net-Results for the first nine months of 1997 include gains 
totaling $18.0 million related to US Airways' sale of eleven B737-
200 and one F28-4000 aircraft. Results for the first nine months 
of 1996 included losses totaling $10.5 million related to US 
Airways' sale of four DC-9 aircraft and its only owned BAe-146 
aircraft and a $9.8 million expense related to US Airways' 
settlement of litigation involving travel agencies.

                                  24
<PAGE>
Provision for Income Taxes-Increased due primarily to increased 
income and an increase in the Company's effective tax rate as a 
result of the Company's projected utilization of all remaining 
alternative minimum tax net operating loss carryforwards during 
1997.

Income per Common Share-During the third quarter of 1997, most of 
the Series B Preferred Stock was converted into 10.6 million 
shares of Common Stock. During the second quarter of 1997, most of 
the Series F Preferred Stock was converted into 14.5 million 
shares of Common Stock. On a weighted average basis, these 
transactions had the effect of increasing Common Stock shares 
outstanding by approximately 8.4 million shares for the first nine 
months of 1997.

     US Airways' traffic levels continue to be bolstered by 
favorable domestic economic conditions. US Airways' yield 
decreased for both the third quarter of 1997 and first nine months 
of 1997 versus the comparable periods in 1996. The yield decreases 
are primarily attributable to increased competitive pressures (see 
"Update on US Airways' Competitive Position" above) and the 
effects of the ticket tax. The ticket tax expired on January 1, 
1996, was reinstated on August 27, 1996, expired again on January 
1, 1997 and once again reinstated effective March 7, 1997. As 
discussed under "Other Information" above, the ticket tax was 
modified and extended during August 1997. Also negatively 
affecting yield, US Airways' average passenger journey increased 
for both the third quarter and first nine months of 1997. US 
Airways selectively increased fares in certain markets up to 5% 
during September 1997.

     Unit costs (cost per ASM) decreased slightly versus 1996 
levels on both a quarter-over-quarter and year-over-year basis. 
Changes in certain operating expenses are discussed above in the 
comparisons of financial results. US Airways' expects its unit 
costs to decrease approximately 1% - 2% for fourth quarter 1997 as 
compared to fourth quarter 1996.

     Capacity (ASMs) increased for both periods in 1997 primarily 
as the result of higher aircraft utilization rates during 1997. 
Aircraft utilization was adversely affected by inclement weather 
during both the first and third quarters of 1996. ASMs increased 
4.5% for the first nine months of 1997 as compared to the same 
period in 1996, but only 1.9% for the third quarter of 1997 as 
compared to the third quarter of 1996 due primarily to schedule 
changes implemented during the third quarter of 1997 and aircraft 
retirements (see also "Efficiency Measures" above). US Airways 
expects capacity to decrease approximately 4% for fourth quarter 
1997 as compared to fourth quarter 1996. As compared to capacity 
for full year 1997, US Airways' capacity for 1998 is expected to 
decrease less than the 3 1/2% - 4% decrease previously announced.

     As discussed above under "Pilots Ratify New Labor Contract" 
and "Affirmation of Airbus Order" and elsewhere in this report, 
recent events may have a significant impact on US Airways' future 
operating and financial statistics.

LIQUIDITY AND CAPITAL RESOURCES

     As of September 30, 1997, the Company's Cash and cash 
equivalents and Short-term investments totaled $2.08 billion. As 
indicated in the Company's Condensed Consolidated Statements of 
Cash Flows (which are also contained in Part I, Item 1A of this 
report), net cash provided by operating activities during the 
first nine months of 1997 was $669.2 million, due primarily to the 
effects of factors discussed above under "Results of Operations." 
The Company is unable to predict the impact of recent events 
involving US Airways' labor costs and agreements to purchase new 
aircraft and jet engines on its operating cash flows (see "Pilots 
Ratify New Labor Contract" and "Affirmation of Airbus Order" 
above). The Company expects decreases in certain future operating 
cash outflows as US Airways replaces several older, diverse 
aircraft types with newer, more efficient aircraft, but may 
experience increases in certain other future operating cash 
outflows as the result of US Airways' growth plans (see "Update on 
US Airways' Competitive Position" above).

                                  26
<PAGE>
     With the reinstatement of the ticket tax during March 1997, 
the Company resumed ticket tax remittances to the federal 
government. The ticket tax was not in effect during the periods 
January 1, 1996-August 27, 1996 and January 1, 1997-March 7, 1997. 
The Company also made profit sharing payments to employees 
totaling $129.1 million during first quarter 1997. These payments 
ended the Company's obligation for profit sharing under its 1992 
Salary Reduction Plan (the related expenses were recognized by the 
Company during 1996 and earlier periods). USAM received 
distributions totaling $17.4 million from its CRS investments 
during the first nine months of 1997, as reflected in the Other 
operating adjustments category (see also "USAM Investments" 
above).

     SAR exercises resulted in cash outflows of $47.4 million 
during the first nine months of 1997. As of September 30, 1997, 
approximately 435,000 SARs granted under the 1992 Stock Option 
Plan were outstanding (4.2 million SARs were outstanding as of 
December 31, 1996).

     Investing activities during the first nine months of 1997 
included cash outflows of $134.7 million for the acquisition of 
assets and cash inflows of $54.3 million related to asset 
dispositions. US Airways' cash outflows related to asset 
acquisitions include $79.7 million for aircraft and aircraft-
related assets, $15.6 million for computer equipment, $14.1 
million for third-party maintenance performed on certain subleased 
aircraft and $6.0 million to purchase slots at Washington National 
Airport. Asset dispositions included cash inflows related to US 
Airways' sale of eleven B737-200, one F28-4000 and one Bae-146 
aircraft. Short-term investments increased $222.8 million from the 
year-end 1996 level due primarily to cash flows generated from 
operations exceeding immediate operational needs, particularly 
during the third quarter of 1997. The net cash used for investing 
activities during the first nine months of 1997 was $56.1 million.

     As discussed under "USAM Investments" above, during July 1997 
USAM received proceeds of $162.0 million in connection with the 
sale of its interest in ATS and proceeds of $62.2 million related 
to the sell-down of its interest in Galileo.

     As of September 30, 1997, current maturities of long-term 
debt had increased to $186.6 million, from $84.3 million at the 
end of 1996. The increase is due mainly to reclassifying the first 
series of US Airways' 1993-A Pass Through Trusts, $75.0 million, 
from long-term to short-term status. US Airways currently expects 
to settle this obligation, which becomes payable on September 1, 
1998, from cash on hand. 

     The Company currently estimates that contributions to its 
defined benefit plans for full-year 1997 will total approximately 
$110 million. The Company estimates it will need to contribute 
less than $20 million to these plans in 1998 in order to meet 
statutory minimum pension funding requirements due primarily to 
favorable returns on assets held by these plans and certain 
changes in assumptions underlying the Company's calculations of 
the funding minimums. The Company's estimates of future pension 
plan contributions are subject to change, including the 
possibility of the Company contributing to these plans in excess 
of minimum funding requirements. As mentioned above under "Pilots 
Ratify New Labor Contract," US Airways' new labor contract with 
its pilots includes a provision for early retirement for up to 325 
pilots which could result in the Company funding certain pilot 
pension plans in excess of funding minimums.

     US Airways is currently reviewing the extent and timing of 
its "aircraft interior standardization program" in light of 
affirming its aircraft and jet engine acquisition agreements and 
its decision to retire its DC-9 aircraft. US Airways is currently 
unable to estimate any reduction in the cost or scope of this 
program as a result of these recent events. 

     Net cash used for financing activities during the first nine 
months of 1997 was $339.7 million. The Company paid dividends 
totaling $172.4 million to holders of its preferred stock during 
the first nine months of 1997 and repurchased the Series T 
Preferred Stock and 1,940.636 shares of Series F Preferred Stock 
during May 1997 for a combined $126.2 million. As discussed above, 

                                  27
<PAGE>
British Airways converted the remaining Series F shares into 
Common Stock and subsequently sold those shares to third parties. 
During August 1997, and also discussed above, the Company 
exercised its right to redeem all of its outstanding Series B 
Preferred Stock-all but approximately 6,000 depositary shares were 
converted into Common Stock prior to the redemption date (for 
which the related cash outflows were $0.3 million). With the 
retirement of the Series B, Series F and Series T Preferred Stock, 
the Company's annual preferred stock dividend burden has been 
reduced by approximately $46 million. Issuances of Common Stock 
related to the exercise of stock options resulted in proceeds of 
$30.5 million. The Company's subsidiaries made scheduled debt 
repayments of approximately $63.1 million and US Airways prepaid 
early capital lease obligations of $9.2 million associated with 
three DC-9 aircraft (and assumed title of the aircraft) during the 
first nine months of 1997.

     The Company expects to satisfy all of its short-term 
liquidity requirements through a combination of cash on hand and 
cash generated from operations. However, the Company remains 
highly leveraged. The Company and US Airways require substantial 
working capital in order to meet scheduled debt and lease payments 
and to finance day-to-day operations. The Company currently does 
not have in place a short-term credit or receivable sale 
facilities. In addition, as discussed previously, US Airways has 
entered into agreements to acquire up to 400 new aircraft and jet 
engines to power these aircraft. These agreements will increase US 
Airways' financing needs and will result in a significant increase 
in its financial obligations and debt burden (see related 
discussion below). Changes in certain factors that are generally 
outside the Company's control, such as an economic downturn, 
additional government regulation, intensified competition from 
lower cost air carriers or operations and increases in the cost of 
aviation fuel, could have a material adverse effect on the 
Company's liquidity, financial condition and results of 
operations. Until US Airways is able to establish a competitive 
cost structure, the Company's results of operations and financial 
condition will be particularly susceptible to adverse changes in 
general economic and market conditions.

     As discussed under "Affirmation of Airbus Order" above, the 
Company has entered into agreements for the acquisition of up to 
400 new aircraft and accompanying jet engines. The minimum 
determinable payments associated with the Company's agreements 
with AVSA and CFMI (including progress payments, payments at 
delivery, buyer-furnished equipment, spares, capitalized interest, 
penalty payments, cancellation fees and/or nonrefundable deposits) 
are currently estimated at $92 million during the fourth quarter 
of 1997, $261 million in 1998, $701 million in 1999, $1.06 billion 
in 2000 and $212 million in 2001. If the Company takes delivery of 
all of the Airbus aircraft it currently has on firm order, the 
aggregate payments for aircraft and related expenditures in 
connection with the acquisition of the aircraft could approximate 
$4.75 billion. The Company anticipates using cash on hand for 
purchase deposits due within the next year and currently plans on 
financing a substantial portion of the remaining commitment. The 
Company has commitments or letters of intent which it believes 
will provide financing for at least 25% of the anticipated 
purchase price of such aircraft. However, further financing or 
internally-generated funds will be needed to satisfy the Company's 
capital commitments for the balance of the aircraft purchase price  
and for other aircraft-related expenditures. Other capital 
expenditures, such as for rotables and other aircraft components, 
are also expected to increase in conjunction with the acquisition 
of the new aircraft and jet engines. There can be no assurance 
that sufficient financing will be available for all aircraft and 
other capital expenditures not covered by committed financing.  

     As discussed under "US Airways Shuttle" above, the Company is 
investigating the purchase of Shuttle, Inc., the owner of the US 
Airways Shuttle. The Company's purchase of Shuttle, Inc. would 
result in a material capital expenditure.

     On October 1, 1997, Standard & Poor's ("S&P") placed the 
credit ratings of US Airways Group and US Airways on CreditWatch 
with positive implications. During July 1997, S&P raised its 
ratings outlook on US Airways Group and US Airways to "Positive" 
from "Developing." Credit
                                  28
<PAGE>
ratings issued by such credit rating agencies can have an effect 
on a company's ability to issue debt or equity securities and the 
effective rate at which such financings are undertaken.

     As of September 30, 1997, the Company's ratio of current 
assets to current liabilities was approximately 1.05 to 1 and the 
Company's debt to equity ratio was 9.31 or 10.68 if the Series H 
Preferred Stock is included in the calculation as debt (the Series 
H Preferred Stock is mandatorily redeemable, but convertible into 
Common Stock).


PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

     As previously disclosed, The Boeing Company ("Boeing") has 
filed suit against US Airways, Inc. ("US Airways")  in state court 
in King County, Washington seeking unspecified damages for alleged 
breach of two aircraft purchase agreements concerning, 
respectively, eight B757-200 aircraft and 40 B737-Series aircraft. 
On October 31, 1997, US Airways filed an answer and counterclaim 
to Boeing's complaint denying liability and seeking recovery from 
Boeing of approximately $45 million in equipment purchase deposits 
and past overcharges.

     US Airways intends to vigorously defend against Boeing's 
lawsuit and to prosecute its counterclaim. US Airways cannot 
predict the outcome of the lawsuit or whether US Airways' results 
of operations and financial condition would be materially affected 
as a result of the lawsuit.

EXHIBIT 4

                CORRECTED CERTIFICATE OF DESIGNATION    

                                  of

        SERIES H SENIOR CUMULATIVE CONVERTIBLE PREFERRED STOCK

                                  of

                      US AIRWAYS GROUP, INC.

     Pursuant to Section 103(f) of the General Corporation Law
                       of the State of Delaware

               US Airways Group, Inc., a Delaware corporation (the 
"Corporation"), filed a Certificate of Designation of Series H 
Senior Cumulative Convertible Preferred Stock of the Corporation 
on August 15, 1997, pursuant to, and in accordance with, the 
provisions of Section 151 of the General Corporation Law of the 
State of Delaware, which contained errors misstating an arithmet-
ical calculation in Sections 3(a) and 8(a).  The Certificate of 
Designation of Series H Senior Cumulative Convertible Preferred 
Stock of the Corporation is set forth in its corrected form below:

               Section 1.  DESIGNATION AND AMOUNT.

               The shares of such series shall be designated as 
the "Series H Senior Cumulative Convertible Preferred Stock" (the 
"Series H Preferred Stock") and the number of shares initially 
constituting such series shall be 358,000, which number may be 
decreased (but not increased) by the Board of Directors without a 
vote of stockholders; PROVIDED, HOWEVER, that such number may not 
be decreased below the number of then currently outstanding shares 
of Series H Preferred Stock.

                Section 2.  DIVIDENDS AND DISTRIBUTIONS.

               (a)     The holders of shares of Series H Preferred 
Stock, in preference to the holders of shares of the Common Stock, 
$1 par value (the "Common Stock"), of the Corporation and of any 
other capital stock of the Corporation ranking junior to the 
Series H Preferred Stock as to payment of dividends, shall be 
entitled to receive, when, as and if declared by the Board of 
Directors out of funds of the Corporation legally available for 
the payment of dividends, cumulative dividends payable in cash at 
the annual rate of $92.50 per share, and no more, in equal 
quarterly payments on March 31, June 30, September 30 and December 
31 (or if any of such days is not a Business Day, the Business Day 
next preceding such day) in each year (each such date being 
<PAGE>
referred to herein as a "Quarterly Dividend Payment Date", and any 
dividend not paid on such date being referred to herein as "past 
due"), commencing on the first Quarterly Dividend Payment Date 
which is at least 10 days after the date of original issue of the 
Series H Preferred Stock; PROVIDED, HOWEVER, that if any appli-
cable dividend payment or redemption payment is not made on a 
Quarterly Dividend Payment Date or the date set for such redemp-
tion, respectively, thereafter all such dividend payments and 
redemption payments that are past due and unpaid shall accrue 
interest at (A) the higher of (x) an annual rate of 9 1/4% or (y) 
an annual rate (determined as of each Quarterly Dividend Payment 
Date) equal to 5% plus the "prime rate" as reported in THE WALL 
STREET JOURNAL (or, if not reported therein, as such rate may be 
from time to time publicly announced by The Chase Manhattan Bank) 
on the date of publication closest to the date of determination or 
(B) such lesser rate as may be the maximum rate that is permitted 
by applicable law (in either case compounded quarterly), with the 
amount of such interest added to accrued dividend payments or 
redemption payments, respectively, until all such dividend 
payments and redemption payments shall have been paid in full (or 
declared and funds sufficient therefor Set Apart for Payment); and 
PROVIDED, FURTHER, that in the case of a redemption payment 
required to be made  pursuant to  Section 5(d) hereof that is not 
made on the date set for such redemption the interest accrued 
pursuant to clause (y) of the previous proviso shall increase each 
month by an annual rate of 100 basis points, up to a maximum of 
19%, or  such lesser rate as may be the maximum rate that is 
permitted by applicable law.

               (b)     Dividends payable pursuant to paragraph 
(a)of this Section 2 shall begin to accrue and be cumulative from 
July 1, 1997.  The amount of dividends so payable shall be deter-
mined on the basis of twelve 30-day months and a 360-day year.  
Accrued but unpaid dividends shall bear interest as provided in 
the last proviso of paragraph (a) of this Section 2.  Dividends 
paid on the shares of Series H Preferred Stock in an amount less 
than the total amount of such dividends at the time accrued and 
payable on such shares shall be allocated pro rata on a share-by-
share basis among all such shares at the time outstanding.  The 
Board of Directors may fix a record date for the determination of 
holders of shares of Series H Preferred Stock entitled to receive 
payment of a dividend declared thereon, which record date shall be 
no more than 60 days nor less than 10 days prior to the date fixed 
for the payment thereof.

               (c)     In case the Corporation shall at any time 
or from time to time declare, order, pay or make a dividend or 
other distribution (including, without limitation, any 
distribution of stock or other securities or property or rights or 
<PAGE>
warrants to subscribe for securities of the Corporation or any of 
its Subsidiaries by way of dividend or spinoff or Rights) on its 
Common Stock, other than (i) dividends payable in cash in an 
aggregate amount in any fiscal year which, when declared, are not 
expected to exceed the net income of the Corporation during such 
year from continuing operations before extraordinary items, as 
determined in accordance with generally accepted accounting 
principles consistently applied in accordance with past practice, 
or (ii) any dividend or distribution of shares of Common Stock, 
then, and in each such case (a "Triggering Distribution"), the 
holders of shares of Series H Preferred Stock shall be entitled to 
receive from the Corporation, with respect to each share of Series 
H Preferred Stock held, the same dividend or distribution received 
by a holder of the number of shares of Common Stock into which 
such share of Series H Preferred Stock is convertible on the 
record date for such dividend or distribution.  Any such dividend 
or distribution shall be declared, ordered, paid or made on the 
Series H Preferred Stock at the same time such dividend or 
distribution is declared, ordered, paid or made on the Common 
Stock.

               (d)     The holders of shares of Series H Preferred 
Stock shall not be entitled to receive any dividends or other 
distributions except as provided in this Certificate of Designa-
tion of Series H Senior Cumulative Convertible Preferred Stock.

               Section 3.  VOTING RIGHTS.

          In addition to any voting rights provided elsewhere 
herein and in the Corporation's Restated Certificate of Incorpo-
ration, as it may be amended or restated from time to time (the 
"Certificate of Incorporation"), and any voting rights provided by 
law, the holders of shares of Series H Preferred Stock shall have 
the following voting rights:

               (a)     Each share of Series H Preferred Stock 
shall be entitled to 25.8099 votes, subject to adjustment in the 
manner set forth in paragraph (b) of Section 8.  Except as other-
wise provided herein, or by the Certificate of Incorporation, or 
by law, the shares of Series H Preferred Stock and the shares of 
Common Stock (and any other shares of capital stock of the 
Corporation at the time entitled thereto) shall vote together as 
one class on all matters submitted to a vote of stockholders of 
the Corporation.

               (b)     So long as any shares of Series H Preferred 
Stock shall be outstanding and unless the consent or approval of a 
<PAGE>
greater number of shares shall then be required by law, without 
first obtaining the consent or approval of the holders of at least 
two-thirds of the number of then-outstanding shares of Series H 
Preferred Stock, voting as a single class, given in person or by 
proxy at a meeting at which the holders of such shares shall be 
entitled to vote separately as a class, or by written consent, the 
Corporation shall not:  (i) authorize or create any class or 
series, or any shares of any class or series, of stock having any 
preference or priority as to dividends or upon redemption, 
liquidation, dissolution, or winding up over the Series H Pre-
ferred Stock, or redeemable prior to the time that the Series H 
Preferred Stock may be redeemable pursuant to Section 5 ("Senior 
Stock"); (ii) authorize or create any class or series, or any 
shares of any class or series, of stock ranking on a parity 
(either as to dividends or upon liquidation, dissolution or 
winding up) with the Series H Preferred Stock or redeemable at or 
prior to the time that the Series H Preferred Stock may be 
redeemable pursuant to Section 5 ("Parity Stock"), PROVIDED, 
HOWEVER, that no such vote shall be required with respect to the 
authorization or creation by the Corporation of one or more new 
series of Senior Preferred Stock or Preferred Stock that is Parity 
Stock if (A) the aggregate purchase price (excluding transaction-
related expenses) of all shares of such series is equal to or 
greater than the aggregate liquidation preference of all shares of 
such series, (B) the aggregate liquidation preference (excluding 
accrued but unpaid dividends) of all shares of such series of 
Preferred Stock does not exceed $150,000,000, and (C) shares of 
any such new series shall be issued only to an employee stock 
ownership plan, employee stock ownership trust or other similar 
arrangement organized and maintained by the Corporation for the 
benefit of its employees; (iii) reclassify any shares of stock of 
the Corporation into shares of Senior Stock or Parity Stock; (iv) 
authorize any security exchangeable for, convertible into, or 
evidencing the right to purchase any shares of Senior Stock or 
Parity Stock: (v) amend, alter or repeal the Certificate of 
Incorporation to alter or change the preferences, rights or powers 
of the Series H Preferred Stock so as to affect the Series H 
Preferred Stock adversely or to increase the authorized number of 
shares of Series H Preferred Stock; or (vi) effect the voluntary 
liquidation, dissolution or winding up of the Corporation, or the 
sale, lease, conveyance or exchange of all or substantially all of 
the assets, property or business of the Corporation, or the merger 
or consolidation of the Corporation with or into any other 
corporation; PROVIEDED, HOWEVER, that no separate vote of the 
holders of the Series H Preferred Stock as a class shall be 
required in the case of a merger or consolidation or a sale, 
lease, conveyance or exchange of all or substantially all of the 
assets, property or business of the Corporation (such transactions 
<PAGE>
being hereinafter in this proviso referred to as a "reorga-
nization") if (A) the resulting, surviving or acquiring corpora
tion will have after such reorganization no stock either autho-
rized or outstanding ranking prior to, or on a parity with, the 
Series H Preferred Stock or the stock of the resulting, surviving 
or acquiring corporation issued in exchange therefor (except such 
stock of the Corporation as may have been authorized or outstand-
ing immediately preceding such reorganization, or such stock of 
the resulting, surviving or acquiring corporation containing 
substantially the same relative rights and preferences as the 
stock of the Corporation for which it may be exchanged ("Exchanged 
Stock"), which Exchanged Stock was outstanding immediately 
preceding such reorganization and at such time ranked prior to, or 
on a parity with, the Series H Preferred Stock) and (B) each 
holder of shares of Series H Preferred Stock immediately preceding 
such reorganization will receive in exchange therefor the same 
number of shares of stock, with substantially the same 
preferences, rights and powers, of the resulting, surviving, or 
acquiring corporation or the Corporation is the surviving corpo-
ration and the Series H Preferred Stock remains outstanding 
without change to its preferences, rights and powers, provided 
that nothing in this proviso shall require that such other stock 
or Series H Preferred Stock have any rights upon conversion save 
those specified in Section 8(b)(iii) hereof.

               (c)     Whenever (i) dividends payable on shares of 
the Series H Preferred Stock pursuant to the terms of paragraphs 
(a) and (b) of Section 2 shall have been in arrears and not paid 
in full at or before thirty (30) days following any Quarterly 
Dividend Payment Date (a "Dividend Default"), thereafter and until 
all such dividends shall have been paid in full or declared and 
Set Apart for Payment, or (ii) the Corporation shall have violated 
any of the covenants contained in Section 4 and such violation 
shall be continuing, or (iii) the Corporation shall have not 
redeemed shares of Series H Preferred Stock within five (5) 
Business Days of the date such redemption is required by Section 5 
(a "Redemption Default"), thereafter and until such redemption 
shall have been performed or all funds necessary therefor Set 
Apart for Payment, or (iv) the Corporation shall have not 
distributed any dividend or other distribution distributable to 
the holders of shares of Series H Preferred Stock pursuant to the 
terms of paragraph (c) of Section 2 within five (5) Business Days 
of the date such distribution is required by paragraph (c) of 
Section 2 (a "Distribution Default"), thereafter and until such 
distribution shall have been made, the holders of shares of Series 
H Preferred Stock shall have the right, notwithstanding anything 
to the contrary in the Corporation's Certificate of Incorporation 
or By-Laws, voting together as a single class, to elect two 
<PAGE>
directors.  Such right of the holders of Series H Preferred Stock 
to vote for the election of directors may be exercised at any 
annual meeting or at any special meeting called for such purpose 
as hereinafter provided or at any adjournment thereof, or by the 
written consent, delivered to the Secretary of the Corporation, of 
the holders of a majority of all outstanding shares of Series H 
Preferred Stock as of the record date of such written consent, 
until any Dividend Default, Redemption Default and Distribution 
Default shall have been cured, and any covenant violation shall 
cease to be continuing, at which time the term of office of the 
directors so elected shall terminate automatically.  So long as 
such right to vote continues (and unless such right has been 
exercised by written consent of the holders of a majority of the 
outstanding shares of Series H Preferred Stock as hereinabove 
authorized), the Secretary of the Corporation may call, and upon 
the written request of the holders of record of a majority of the 
outstanding shares of Series H Preferred Stock addressed to him at 
the principal office of the Corporation shall call, a special 
meeting of the holders of such shares for the election of such 
directors as provided herein.  Such meeting shall be held within 
30 days after delivery of such request to the Secretary, at the 
place and upon the notice provided by law and in the By-Laws or in 
the notice of meeting for the holding of meetings of stockholders. 
 No such special meeting or adjournment thereof shall be held on a 
date less than 30 days before an annual meeting of stockholders or 
any special meeting in lieu thereof.  If at any such annual or 
special meeting or any adjournment thereof the holders of a 
majority of  the then outstanding shares of Series H Preferred 
Stock entitled to vote in such election shall be present or 
represented by proxy, or if the holders of a majority of the 
outstanding shares of Series H Preferred Stock shall have acted by 
written consent in lieu of a meeting with respect thereto, then 
the authorized number of directors shall be increased by two and 
the holders of the Series H Preferred Stock shall be entitled to 
elect such additional directors.  The absence of a quorum of the 
holders of any other class or series of capital stock of the 
Corporation at any such annual or special meeting shall not affect 
the exercise by the holders of the Series H Preferred Stock of 
such voting rights.  Directors so elected shall serve until the 
next annual meeting or until their successors shall be elected and 
shall qualify, unless the term of office of the persons so elected 
as directors shall have terminated under the circumstances set 
forth in the second sentence of this paragraph (c).  In case of 
any vacancy occurring among the directors elected by the holders 
of the Series H Preferred Stock as a class, the remaining director 
who shall have been so elected may appoint a successor to hold 
office for the unexpired term of the director whose place shall be 
vacant.  If both directors so elected by the holders of Series H 
<PAGE>
Preferred Stock as a class shall cease to serve as directors 
before their terms shall expire, the holders of the Series H 
Preferred Stock then outstanding and entitled to vote for such 
directors may, by written consent as hereinabove provided, or at a 
special meeting of such holders called as provided above, elect 
successors to hold office for the unexpired terms of the directors 
whose places shall be vacant.  After the holders of Series H 
Preferred Stock shall have exercised their right to elect direc-
tors pursuant to the terms of this paragraph (c), the authorized 
number of directors shall not be increased or decreased, regard-
less of the terms of any Junior Stock, or decreased, regardless of 
the terms of any other stock of the Corporation, except by a class 
vote of the holders of Series H Preferred Stock as provided above. 
 The rights of the holders of Series H Preferred Stock to elect 
directors pursuant to the terms of this paragraph (c) shall not be 
adversely affected by the voting or other rights applicable to any 
other security of the Corporation.  Notwithstanding anything to 
the contrary in this paragraph (c), the directors elected or 
appointed pursuant to this paragraph (c) as a result of a Dividend 
Default shall not be elected or appointed until they have been 
approved by the Corporation, such approval not to be unreasonably 
withheld or delayed.

               (d)     Except as provided in this Certificate of 
Designation of Series H Senior Cumulative Convertible Preferred 
Stock (including, without limitation, the right to vote with the 
Common Stock on all matters submitted to a vote of stockholders of 
the Corporation as set forth in paragraph (a) of this Section 3) 
or in the Certificate of Incorporation, or as required by law, the 
holders of shares of Series H Preferred Stock shall have no voting 
rights and their consent shall not be required for the taking of 
any corporate action.

     Section 4.  CERTAIN RESTRICTIONS.

               (a)     Whenever (i) a Dividend Default has 
occurred, thereafter and until all accrued and unpaid dividends, 
whether or not declared, shall have been paid in full or declared 
and Set Apart for Payment, or (ii) a Distribution Default has 
occurred, thereafter and until all dividends or other distribu-
tions distributable pursuant to the terms of paragraph (c) of 
Section 2 shall have been distributed, or (iii) a Redemption 
Default has occurred, thereafter and until all mandatory redemp-
tion payments shall have been made or all necessary funds shall 
have been Set Apart for Payment, the Corporation shall not, nor 
shall it permit any of its Subsidiaries to:  (A) declare or pay 
dividends, or make any other distributions, on any shares of 
Common Stock or other capital stock ranking junior (either as to 
<PAGE>
dividends or upon liquidation, dissolution or winding up) to the 
Series H Preferred Stock, other than dividends or distributions 
payable in Junior Stock or in Rights; (B) declare or pay divi-
dends, or make any other distributions, on any shares of Parity 
Stock, other than dividends or distributions payable in Junior 
Stock or Rights, except dividends paid ratably on the Series H 
Preferred Stock and all Parity Stock on which dividends are 
payable or in arrears, in proportion to the total amounts to which 
the holders of all such shares are then entitled; (C) redeem or 
purchase or otherwise acquire for consideration (other than Junior 
Stock) any shares of Junior Stock or Parity Stock (other than, 
with respect to Parity Stock, ratably with the Series H Preferred 
Stock); or (D) purchase or otherwise acquire for consideration any 
shares of Series H Preferred Stock; PROVIDED, HOWEVER, that the 
Corporation may redeem shares of the Series H Preferred Stock 
pursuant to Section 5 hereof and may purchase Series H Preferred 
Stock offered for sale to the Corporation.

               (b)     Notwithstanding the foregoing, nothing 
herein shall prevent the Corporation from (i) declaring a dividend 
or distribution of Rights (subject to compliance with paragraph 
(c) of Section 2), or issuing Rights in connection with the 
issuance of Junior Stock, Parity Stock or the Series H Preferred 
Stock or (ii) redeeming Rights at a price not to exceed $.03 per 
Right.

               (c)     The Corporation shall not permit any 
Subsidiary of the Corporation to purchase or otherwise acquire for 
consideration any shares of capital stock of the Corporation 
unless the Corporation could, pursuant to paragraph (a) of this 
Section 4, purchase or otherwise acquire such shares at such time 
and in such manner.

          Section 5.  REDEMPTION.

               (a)     On August 7, 1999 (if any shares of Series 
H Preferred Stock remain outstanding), the Corporation shall 
redeem all outstanding shares of Series H Preferred Stock, by 
paying therefor in cash $1,000 per share plus all Accrued 
Dividends thereon to the date of redemption.

               (b)     The Corporation shall have no right to 
redeem any share of Series H Preferred Stock prior to March 15, 
1998.

               (c)     On and after March 15, 1998, the Corpora-
tion shall have the right, at its sole option and election, to 
redeem, at any time, all (but not less than all) of the outstand
<PAGE>
ing shares of Series H Preferred Stock by paying therefor in cash 
$1,150 per share plus all Accrued Dividends thereon to the date of 
redemption.

               (d)     In the event there occurs a Change in Con-
trol, any holder of shares of Series H Preferred Stock may require 
the Corporation to redeem all (but not less than all) of the 
shares of Series H Preferred Stock held by such holder at a price 
equal to, at the sole option and election of the holder, either, 
(i) $1,000 per share, or (ii) an amount per share equal to the 
Event Price of the shares of Common Stock into which such share of 
Series H Preferred Stock is then convertible, plus, in either 
case, all Accrued Dividends thereon to the date of redemption.

               (e)     In the event that the Corporation shall 
redeem, repurchase, exchange any security or property for, or 
otherwise acquire for consideration any shares of Common Stock 
(excluding any transaction to which clause (b)(iii) of Section 8 
hereof applies) at a price equal to or greater than the Conversion 
Price, then, and in each such case, any holder of shares of Series 
H Preferred Stock may require the Corporation, at the sole option 
and election of the holder, to redeem a number of shares of such 
holder's Series H Preferred Stock which does not exceed the 
product (rounded, upward or downward, to the nearest whole share) 
of (A) the percentage (expressed as a decimal) of the 
Corporation's Common Stock outstanding immediately prior to the 
acquisition that the Corporation acquired through redemption, 
repurchase, exchange or otherwise, multiplied by (B) the total 
number of shares of Series H Preferred Stock held by such holder, 
at a price per share equal to the sum of (X) the product of (1) 
the number of shares of the Corporation's Common Stock into which 
a share of the Series H Preferred Stock is convertible immediately 
prior to such redemption, repurchase, exchange or other 
acquisition, multiplied by (2) the per share price (or the Fair 
Market Value in the event of non-cash consideration) paid for a 
share of Common Stock in such redemption, repurchase, exchange or 
other acquisition, plus (Y) all Accrued Dividends thereon to the 
date of redemption.

               (f)(i) Notice of any redemption of shares of Series 
H Preferred Stock pursuant to paragraphs (a), (b) or (c) of this 
Section 5 shall be given by publication in a newspaper of general 
circulation in the Borough of Manhattan not less than thirty nor 
more than sixty days prior to the date fixed for redemption, if 
the Series H Preferred Stock is listed on any national securities 
exchange or traded in the over-the-counter market; and, in any 
case, a similar notice shall be mailed not less than thirty, but 

<PAGE>
not more than sixty, days prior to such date to each holder of 
shares of Series H Preferred Stock to be redeemed, at such 
holder's address as it appears on the transfer books of the 
Corporation.  In order to facilitate the redemption of shares of 
Series H Preferred Stock, the Board of Directors may fix a record 
date for the determination of shares of Series H Preferred Stock 
to be redeemed, not more than sixty days or less than thirty days 
prior to the date fixed for such redemption.

                    (ii)   Until any record holder of shares of 
Series H Preferred Stock shall have notified the Corporation in 
writing that notices of events which, pursuant to paragraphs (d) 
or (e) of this Section 5, give the holder or holders the right to 
require the Corporation to redeem any of such shares should be 
given by the Corporation in accordance with the terms of subpara-
graph (iii) below, notice of an event which, pursuant to para-
graphs (d) or (e) of this Section 5 gives the holder or holders 
the right to require the Corporation to redeem any of such shares, 
shall be given by telex or telecopy to the holders of the Series H 
Preferred Stock sufficiently in advance of such event that such 
holders can, by similar telexed or telecopied notice in advance of 
the event, elect to have such shares of Series H Preferred Stock 
eligible for redemption and so held redeemed by the Corporation, 
and if such an election is made the Corporation shall redeem the 
number of shares so specified concurrently with the event.  It is 
the intent of the Corporation in the circumstances described in 
the preceding sentence to provide notice and the opportunity for 
redemption at the earliest possible time, so that if it is not 
possible to provide notice in advance of a specified event, notice 
shall be given as soon as possible thereafter so that the holder 
or holders, if they elect to redeem, will be entitled to redeem, 
and the Corporation will effect redemption of the shares 
specified, as soon as possible thereafter.  Any election by a 
holder to redeem pursuant to paragraphs (d) and (e) of this 
Section 5, specifying the number of shares to be redeemed, must be 
made in writing (which may be telexed, telecopied, or otherwise 
delivered) within the later of (A) fifteen (15) Business Days 
following receipt by the holder of the telexed or telecopied 
notice required by this subparagraph, or (B) in the event of a 
tender or exchange offer, the consummation of such offer, and the 
redemption date shall be no later than the day following receipt 
by the Corporation of such election.  Failure of the Corporation 
to give any notice required by this subparagraph (ii), or the 
formal insufficiency of any such notice, shall not prejudice the 
rights of any holders of shares of Series H Preferred Stock to 
cause the Corporation to redeem any such shares held by them.


                    (iii)  If any record holder of shares of 
<PAGE>
Series H Preferred Stock shall have notified the Corporation in 
writing that notice of redemption pursuant to paragraphs (d) or 
(e) of this Section 5 should be given by the Corporation in 
accordance with the terms of this subparagraph (iii), rather than 
in accordance with the terms of subparagraph (ii) above, then and 
thereafter, on the date of an event giving a holder of shares of 
Series H Preferred Stock the right, pursuant to paragraphs (d) or 
(e) of this Section 5, to require the Corporation to redeem any of 
such shares, the Corporation shall give notice by mail to each 
holder of Series H Preferred Stock, at such holder's address as it 
appears on the transfer books of the Corporation, of such event, 
which notice shall set forth each holder's right to require the 
Corporation to redeem any or all shares of Series H Preferred 
Stock held by him which are eligible for redemption pursuant to 
the terms of paragraphs (d) or (e), the redemption date (which 
date shall be twenty (20) days following the date of such mailed 
notice), and the procedures to be followed by such holder in 
exercising his right to cause such redemption; and, as soon as 
practical, if the Series H Preferred Stock is listed on any 
national securities exchange or traded in the over-the-counter 
market, a similar notice shall be given by publication in a 
newspaper of general circulation in the Borough of Manhattan.  In 
the event a record holder of shares of Series H Preferred Stock 
shall elect to require the Corporation to redeem any or all such 
shares of Series H Preferred Stock pursuant to paragraphs (d) or 
(e) of this Section 5, such holder shall deliver within twenty 
(20) calendar days of the mailing to him of the Corporation's 
notice described in this subparagraph (iii), a written notice to 
the Corporation so stating, specifying the number of shares to be 
redeemed pursuant to paragraphs (d) or (e) of this Section 5.  The 
Corporation shall, in accordance with the terms hereof, redeem the 
number of shares so specified on the date fixed for redemption.  
Failure of the Corporation to give any notice required by this 
subparagraph (iii), or the formal insufficiency of any such 
notice, shall not prejudice the rights of any holders of shares of 
Series H Preferred Stock to cause the Corporation to redeem any 
such shares held by them.

                    (iv)   Notice having been given pursuant to 
paragraph (f) of this Section 5, from and after the date specified 
therein as the date of redemption, unless default shall be made by 
the Corporation in providing for the payment of the applicable 
redemption price, all dividends on the Series H Preferred Stock 
thereby called for redemption shall cease to accrue, and from and 
after the date of redemption so specified, unless default shall be 
made by the Corporation as aforesaid, or from and after the date 
(prior to the date of redemption so 
<PAGE>
specified) on which the Corporation shall provide for the payment 
of the redemption price 
by depositing the requisite amount of moneys (and other property, 
if applicable) with a bank or trust company doing business in the 
Borough of Manhattan, The City of New York, and having a capital 
and surplus of at least  $50,000,000, PROVIDED that the notice of 
redemption shall state the intention of the Corporation to deposit 
such moneys (and other property, if applicable) on a date in such 
notice specified, all rights of the holders thereof as 
stockholders of the Corporation, except the right to receive the 
applicable redemption price (but without interest) and except the 
right to exercise any privileges of conversion, shall cease and 
terminate.  Any interest allowed on moneys so deposited shall be 
paid to the Corporation.  Any moneys (and other property, if 
applicable) so deposited which shall remain unclaimed by the 
holders of such Series H Preferred Stock at the end of six years 
after the redemption date shall become the property of, and be 
paid by such bank or trust company to, the Corporation.  If the 
Corporation shall default in providing for the redemption price as 
required pursuant to this Section 5, interest on such redemption 
price shall accrue and be added to the required redemption 
payments as provided in paragraph (a) of Section 2.  Except for 
any amounts deposited in payment of Accrued Dividends, in the 
event that moneys are deposited pursuant to this paragraph in 
respect of shares of Series H Preferred Stock that are converted 
in accordance with the provisions of Section 8, such moneys shall, 
upon such conversion revert to the general funds of the 
Corporation, and upon demand, such bank or trust company shall pay 
over to the Corporation such moneys and shall be relieved of all 
responsibility to the holders of such converted shares in respect 
thereof.

          Section 1.  REACQUIRED SHARES.

          Any shares of Series H Preferred Stock converted, 
redeemed, purchased or otherwise acquired by the Corporation in 
any manner whatsoever shall be retired and cancelled promptly 
after the acquisition thereof, and, if necessary to provide for 
the lawful redemption or purchase of such shares, the capital 
represented by such shares shall be reduced in accordance with the 
General Corporation Law of the State of Delaware.  All such shares 
shall upon their cancellation become authorized but unissued 
shares of Senior Preferred Stock, without par value, of the 
Corporation and may be reissued as part of another series of 
Senior Preferred Stock, without par value, of the Corporation 
subject to the conditions or restrictions on authorizing or 
creating any class or series, or any shares of any class or 
<PAGE>
series, set forth in paragraph (b) of Section 3.

      
          Section 2.  LIQUIDATION, DISSOLUTIONOR WINDING UP.

               (a)     If the Corporation shall adopt a plan of 
liquidation or of dissolution, or commence a voluntary case under 
the Federal bankruptcy laws or any other applicable state or 
Federal bankruptcy, insolvency or similar law, or consent to the 
entry of an order for relief in any involuntary case under any 
such law or to the appointment of a receiver, liquidator, as-
signee, custodian, trustee or sequestrator (or similar official) 
of the Corporation or of any substantial part of its property, or 
make an assignment for the benefit of its creditors, or admit in 
writing its inability to pay its debts generally as they become 
due and on account of such event the Corporation shall liquidate, 
dissolve or wind up, or upon any other liquidation, dissolution or 
winding up of the Corporation, no distribution shall be made (i) 
to the holders of shares of Junior Stock, unless, prior thereto, 
the holders of shares of Series H Preferred Stock shall have 
received $1,000 per share plus all Accrued Dividends thereon to 
the date of such payment or (ii) to the holders of shares of 
Parity Stock, except distributions made ratably on the Series H 
Preferred Stock and all such Parity Stock in proportion to the 
total amounts to which the holders of all such shares are entitled 
upon such liquidation, dissolution or winding up of the Corpora-
tion.

               (b)     Neither the consolidation, merger or other 
business combination of the Corporation with or into any other 
Person or Persons nor the sale, lease, exchange or conveyance of 
all or any part of the property, assets or business of the 
Corporation to a Person or Persons other than the holders of the 
Corporation's Junior Stock, shall be deemed to be a liquidation, 
dissolution or winding up of the Corporation for purposes of this 
Section 7.

          Section 3.  CONVERSION.

          Each share of Series H Preferred Stock may, at the 
option of the holder thereof, be converted into shares of Common 
Stock, on the terms and conditions set forth in this Section 8, at 
any time.
<PAGE>
               (a)     Subject to the provisions for adjustment 
hereinafter set forth, each share of Series H Preferred Stock 
shall be convertible in the manner hereinafter set forth into 
<PAGE>
25.8099 fully paid and nonassessable shares of Common Stock.

               (b)     The number of shares of Common Stock into 
which each share of Series H Preferred Stock is convertible, and 
the number of votes to which the holder of a share of Series H 
Preferred Stock is entitled pursuant to paragraph (a) of Section 
3, shall be subject to adjustment from time to time as follows:

               (i)  In case the Corporation shall at any time or 
from time to time declare a dividend, or make a distribution, on 
the outstanding shares of Common Stock in shares of Common Stock 
or subdivide or reclassify the outstanding shares of Common Stock 
into a greater number of shares or combine or reclassify the 
outstanding shares of Common Stock into a smaller number of shares 
of Common Stock, then, and in each such case,

                         (A)  the number of shares of Common Stock 
into which each share of Series H Preferred Stock is convertible 
shall be adjusted so that the holder of each share thereof shall 
be entitled to receive, upon the conversion thereof, the number of 
shares of Common Stock which the holder of a share of Series H 
Preferred Stock would have been entitled to receive after the 
happening of any of the events described above had such share been 
converted immediately prior to the happening of such event or the 
record date therefor, whichever is earlier;

                         (B)     the number of votes to which a 
holder of a share of Series H Preferred Stock is entitled pursuant 
to paragraph (a) of Section 3 shall be adjusted so that, after the 
happening of any of the events described above, such holder shall 
be entitled to a number of votes equal to (I) the number of votes 
to which such holder was entitled pursuant to paragraph (a) of 
Section 3 immediately prior to such happening multiplied by (II) a 
fraction, the numerator of which is the number of shares of Common 
Stock into which one share of Series H Preferred Stock was 
convertible immediately after such happening and the denominator 
of which is the number of shares of Common Stock into which one 
share of Series H Preferred Stock was convertible immediately 
prior to such happening; and

                         (C)     an adjustment made pursuant to 
this clause (i) shall become effective (I) in the case of any such 
dividend or distribution, (1) immediately after the close of 
business on the record date for the determination of holders of 
shares of Common Stock entitled to receive such dividend or 
distribution, for purposes of subclause (A), and (2) immediately 
after the close of business on the date of payment of such 
<PAGE>
dividend or distribution, for purposes of subclause (B), or (II) 
in the case of any such subdivision, reclassification or combina-
tion, at the close of business on the day upon which such corpo-
rate action becomes effective, for purposes of both subclause (A) 
and subclause (B).

                    (ii)  In case the Corporation shall issue 
shares of Common Stock (or rights or warrants or other securities 
convertible into or exchangeable for shares of Common Stock) at a 
price per share (or having an exercise or conversion price per 
share) less than the Conversion Price as of the date of issuance 
of such shares (or of such rights, warrants or other convertible 
securities), other than (X) in a transaction to which paragraph 
(c) of Section 2 or subparagraph (i) of this paragraph (b) is 
applicable, (Y) pursuant to any plan providing for the reinvest-
ment of dividends or interest payable on securities of the 
Corporation, and the investment of additional option amounts, in 
shares of Common Stock, in any such case at a price per share of 
not less than 95% of the current market price (determined as 
provided in such plans) per share of Common Stock, or pursuant to 
any employee benefit plan or program of the Corporation or 
pursuant to the Rights, or (Z) as consideration for the acquisi-
tion of a business, then, and in each such case,

                         (A)     the number of shares of Common 
Stock into which each share of Series H Preferred Stock is 
convertible shall be adjusted so that the holder of each share 
thereof shall be entitled to receive, upon the conversion thereof, 
the number of shares of Common Stock determined by multiplying the 
number of shares of Common Stock into which such share was 
convertible on the day immediately prior to such date of issuance 
by a fraction, (I) the numerator of which is the sum of (1) the 
number of shares of Common Stock outstanding on such date and (2) 
the number of additional shares of Common Stock issued (or into 
which the convertible securities may convert), and (II) the 
denominator of which is the sum of (1) the number of shares of 
Common Stock outstanding on such date and (2) the number of shares 
of Common Stock which the aggregate consideration receivable by 
the Corporation for the total number of shares of Common Stock so 
issued (or into which the convertible securities may convert) 
would purchase at the Conversion Price on such date.  For purposes 
of this subparagraph, the aggregate consideration receivable by 
the Corporation in connection with the issuance of shares of 
Common Stock or of securities convertible into shares of Common 
Stock shall be deemed to be equal to the sum of the net offering 
price (after deduction of underwriting discounts or commissions 
<PAGE>
<PAGE>
and expenses payable to third parties) of all such securities plus 
the minimum aggregate amount, if any, payable upon conversion of 
any such convertible securities into shares of Common Stock;

                         (B)     the number of votes to which a 
holder of a share of Series H Preferred Stock is entitled pursuant 
to paragraph (a) of Section 3 shall be adjusted so that, after the 
happening of any of the events described above, such holder shall 
be entitled to a number of votes equal to (I) the number of votes 
to which such holder was entitled pursuant to paragraph (a) of 
Section 3 immediately prior to such happening multiplied by (II) a 
fraction, the numerator of which is the number of shares of Common 
Stock into which one share of Series H Preferred Stock was 
convertible immediately after such happening and the denominator 
of which is the number of shares of Common Stock into which one 
share of Series H Preferred Stock was convertible immediately 
prior to such happening; and

                         (C)      such adjustment shall become 
effective immediately after the date of such issuance for purposes 
of subclauses (A) and (B).

               (iii)   In case the Corporation shall be a party to 
any transaction (including, without limitation, a merger, consol-
idation, sale of all or substantially all of the Corporation's 
assets, liquidation or recapitalization of the Common Stock and 
excluding any transaction to which clause (i) or (ii) of this 
paragraph (b) applies) in which the previously outstanding Common 
Stock shall be changed into or, pursuant to the operation of law 
or the terms of the transaction to which the Corporation is a 
party, exchanged for different securities of the Corporation or 
common stock or other securities of another Corporation or 
interests in a noncorporate entity or other property (including 
cash) or any combination of any of the foregoing, then, as a 
condition of the consummation of such transaction, lawful and 
adequate provision shall be made so that each holder of shares of 
Series H Preferred Stock shall be entitled, upon conversion, to an 
amount per share equal to (A) the aggregate amount of stock, 
securities, cash and/or any other property (payable in kind), as 
the case may be, into which or for which each share of Common 
Stock is changed or exchanged times (B) the number of shares of 
Common Stock into which a share of Series H Preferred Stock is 
convertible immediately prior to the consummation of such trans-
action.

               (c)     In case the Corporation shall be a party to 
a transaction described in subparagraph (b)(iii) above resulting 
in the change or exchange of the Corporation's Common Stock then, 
<PAGE>
from and after the date of announcement of the pendency of such 
subparagraph (b)(iii) transaction until the effective date 
thereof, each share of Series H Preferred Stock may be converted, 
at the option of the holder thereof, into shares of Common Stock 
on the terms and conditions set forth in this Section 8, and if so 
converted during such period, such holder shall be entitled to 
receive such consideration in exchange for such holder's shares of 
Common Stock as if such holder had been the holder of such shares 
of Common Stock as of the record date for such change or exchange 
of the Common Stock.

               (d)     The Board of Directors may increase the 
number of shares of Common Stock into which each share of Series H 
Preferred Stock may be converted, in addition to the adjustments 
required by this Section 8, as shall be determined by it (as 
evidenced by a resolution of the Board of Directors) to be 
advisable in order to avoid or diminish any income deemed, for 
federal income tax purposes, to be received by any holder of 
shares of Common Stock or Series H Preferred Stock resulting from 
any events or occurrences giving rise to adjustments pursuant to 
this Section 8 or from any other similar event.

               (e)     The holder of any shares of Series H Pre-
ferred Stock may exercise his right to convert such shares into 
shares of Common Stock by surrendering for such purpose to the 
Corporation, at its principal office or at such other office or 
agency maintained by the Corporation for that purpose, a certifi-
cate or certificates representing the shares of Series H Preferred 
Stock to be converted accompanied by a written notice stating that 
such holder elects to convert all or a specified whole number of 
such shares in accordance with the provisions of this Section 8 
and specifying the name or names in which such holder wishes the 
certificate or certificates for shares of Common Stock to be 
issued.  In case such notice shall specify a name or names other 
than that of such holder, such notice shall be accompanied by 
payment of all transfer taxes payable upon the issuance of shares 
of Common Stock in such name or names.  Other than such taxes, the 
Corporation will pay any and all issue and other taxes (other than 
taxes based on income) that may be payable in respect of any issue 
or delivery of shares of Common Stock on conversion of Series H 
Preferred Stock pursuant hereto.  As promptly as practicable, and 
in any event within three Business Days after the surrender of 
such certificate or certificates and the receipt of such notice 
relating thereto and, if applicable, payment of all transfer taxes 
(or the demonstration to the satisfaction of the Corporation that 
such taxes have been paid), the Corporation shall deliver or cause 
<PAGE>
to be delivered (i) certificates representing the number of 
validly issued, fully paid and nonassessable full shares of Common 
Stock to which the holder of shares of Series H Preferred Stock so 
converted shall be entitled and (ii) if less than the full number 
of shares of Series H Preferred Stock evidenced by the surrendered 
certificate or certificates are being converted, a new certificate 
or certificates, of like tenor, for the number of shares evidenced 
by such surrendered certificate or certificates less the number of 
shares converted.  Such conversion shall be deemed to have been 
made at the close of business on the date of giving of such notice 
and of such surrender of the certificate or certificates 
representing the shares of Series H Preferred Stock to be con-
verted so that the rights of the holder thereof as to the shares 
being converted shall cease except for the right to receive shares 
of Common Stock and Accrued Dividends in accordance herewith, and 
the person entitled to receive the shares of Common Stock shall be 
treated for all purposes as having become the record holder of 
such shares of Common Stock at such time.  The Corporation shall 
not be required to convert, and no surrender of shares of Series H 
Preferred Stock shall be effective for that purpose, while the 
transfer books of the Corporation for the Common Stock are closed 
for any purpose (but not for any period in excess of 15 calendar 
days); but the surrender of shares of Series H Preferred Stock for 
conversion during any period while such books are so closed shall 
become effective for conversion immediately upon the reopening of 
such books, as if the conversion had been made on the date such 
shares of Series H Preferred Stock were surrendered, and at the 
conversion rate in effect at the date of such surrender.

               (f)     Shares of Series H Preferred Stock may be 
converted at any time up to the close of business on the second 
Business Day preceding the date fixed for redemption of such 
shares pursuant to Section 5 hereof.

               (g)     Upon conversion of any shares of Series H 
Preferred Stock, the holder thereof shall be entitled to receive 
any Accrued Dividends in respect of the shares so converted to the 
date of conversion.

               (h)    In connection with the conversion of any 
shares of Series H Preferred Stock, no fractions of shares of 
Common Stock shall be issued, but in lieu thereof the Corporation 
shall pay a cash adjustment in respect of such fractional interest 
in an amount equal to such fractional interest multiplied by the 
Current Market Price per share of Common Stock on the day on which 
such shares of Series H Preferred Stock are deemed to have been 
converted.
<PAGE>
               (i)     The Corporation shall at all times reserve 
and keep available out of its authorized and unissued Common 
Stock, solely for the purpose of affecting the conversion of the 
Series H Preferred Stock, such number of shares of Common Stock as 
shall from time to time be sufficient to effect the conversion of 
all then outstanding shares of Series H Preferred Stock.  The 
Corporation shall from time to time, subject to and in accordance 
with the General Corporation Law of the State of Delaware, 
increase the authorized amount of Common Stock if at any time the 
number of authorized shares of Common Stock remaining unissued 
shall not be sufficient to permit the conversion at such time of 
all then outstanding shares of Series H Preferred Stock.

               (j)      In computing the adjustment which a holder 
of Series H Preferred Stock shall receive pursuant to paragraph 
(b) of this Section, the fact that shares of Series H Preferred 
Stock may not be presently convertible shall be ignored and such 
computation shall be made as if such shares were presently 
convertible.

               (k)     Notwithstanding anything else contained 
herein, if adjustments in the number of shares of Common Stock 
into which each share of Series H Preferred Stock is convertible 
have caused the Conversion Price to be lower than the par value, 
if any, of the Common Stock, upon any conversion of shares of 
Series H Preferred Stock the Corporation shall, to the maximum 
extent it is legally able to do so, issue to the converting holder 
the shares of Common Stock into which the shares of Series H 
Preferred Stock being converted are convertible, and, in addition, 
the Corporation shall pay the converting holder an amount in cash 
equal to the Current Market Price of the Common Stock multiplied 
by the number of shares and fractions thereof of Common Stock 
which the converting holder would have been entitled to receive 
except for the limitation on lawful issuance described in this 
paragraph.

      
          Section 4.  REPORTS AS TO ADJUSTMENTS.

          Whenever the number of shares of Common Stock into which 
each share of Series H Preferred Stock is convertible (or the 
number of votes to which each share of Series H Preferred Stock is 
entitled) is adjusted as provided in Section 8 hereof, the 
Corporation shall promptly mail to the holders of record of the 
outstanding shares of Series H Preferred Stock at their respective 
addresses as the same shall appear in the Corporation's stock 
records a notice stating that the number of shares of Common Stock 
<PAGE>
into which the shares of Series H Preferred Stock are convertible 
has been adjusted and setting forth the new number of shares of 
Common Stock (or describing the new stock, securities, cash or 
other property) into which each share of Series H Preferred Stock 
is convertible (and the new number of votes to which each share of 
Series H Preferred Stock is entitled), as a result of such 
adjustment, a brief statement of the facts requiring such 
adjustment and the computation thereof, and when such adjustment 
became effective.

          Section 5.  CERTAIN CONENANTS.

               (a)	The Corporation shall not, without the prior 
written consent of the holders of two-thirds of the outstanding 
shares of Series H Preferred Stock, redeem or repurchase or 
otherwise acquire for consideration, or permit any of its Subsid-
iaries to redeem, repurchase or otherwise acquire for consider-
ation, any shares of Common Stock at a price per share of Common 
Stock less than the Conversion Price, unless the Board of Direc-
tors of the Corporation determines in good faith that the shares 
of Common Stock remaining issued and outstanding upon consummation 
of such redemption, repurchase or other acquisition will have an 
Aggregate Market Value, immediately following consummation of such 
transaction, greater than $1,500,000,000; PROVIDED, HOWEVER, that 
nothing in this paragraph shall prohibit the Corporation or any of 
its Subsidiaries from redeeming, repurchasing or otherwise 
acquiring for consideration (i) up to 15,000,000 shares of Common 
Stock (such number of shares to be subject to adjustment, using 
the method described in Section 8(b)(i)(B) hereof, in the event 
the Common Stock shall be subdivided or reclassified into a 
greater number of shares or combined or reclassified into a 
smaller number of shares) or (ii) any shares of Common Stock 
offered for sale to the Corporation; and PROVIDED FURTHER that the 
provisions of this paragraph (a) shall in no event apply at any 
time after (A) the tender into a tender offer or exchange offer 
that has not occasioned a Change of Control or Prospective Change 
of Control of more than one-third (1/3) of the Series H Preferred 
Stock or (B) the sale, during a tender offer or exchange offer 
that has not occasioned a Change of Control or Prospective Change 
of Control, of more than one-third (1/3) of the Series H Preferred 
Stock or (C) the sale, during a tender offer or exchange offer 
that has not occasioned a Change of Control or Prospective Change 
of Control, of an amount of the Series H Preferred Stock that, 
when added to that amount of the Series H Preferred Stock tendered 
into such tender offer or exchange offer, is more than one-third 
(1/3) of the Series H Preferred Stock (provided that the exception 
<PAGE>
<PAGE>
set forth in this proviso shall not apply unless the Corporation 
would have the right, pursuant to and in accordance with the terms 
of that certain agreement referred to in the first proviso to this 
paragraph (a), to purchase the shares of Series H Preferred Stock 
tendered into such offer prior to their sale pursuant to such 
offer or purchase the shares of Series H Preferred Stock sold 
during the pendency of such offer prior to their sale).

               (b)     INTENTIONALLY OMITTED 

               (c)     The Corporation shall, within three (3) 
Business Days following public announcement of a tender or 
exchange offer by any Person for securities representing fifty 
percent (50%) or more of the combined voting power of the then 
outstanding Voting Stock of the Corporation, which tender or 
exchange offer was not approved by the Board of Directors of the 
Corporation in advance of such public announcement, advise the 
holders of shares of Series H Preferred Stock as to whether or not 
the Corporation has sufficient capital and surplus (as determined 
in accordance with the terms of the General Corporation Law of the 
State of Delaware) to permit the Corporation to redeem the issued 
and outstanding shares of Series H Preferred Stock in accordance 
with the terms of paragraphs (d) and (e) of Section 5.  Such 
notice shall be given by mail (and, if the outstanding shares of 
Series H Preferred Stock are owned by one corporation, or by one 
group of corporations under common corporate control, by telex or 
telecopy) to each holder of Series H Preferred Stock, at such 
holder's address as it appears on the transfer books of the 
Corporation, and, as soon as practical, if the Series H Preferred 
Stock is listed on any national securities exchange or traded in 
the over-the-counter market, a similar notice shall be given by 
publication in a newspaper of general circulation in the Borough 
of Manhattan.

      
         (d)     Any holder of Series H Preferred Stock may 
proceed to protect and enforce its rights and the rights of such 
holders by any available remedy by proceeding at law or in equity 
to protect and enforce any such rights, whether for the specific 
enforcement of any provision of this Certificate of Designation or 
in aid of the exercise of any power granted herein, or to enforce

3 -       CHANGES
          -------

3.1       Specification Change Notices
          ----------------------------

          The Specifications may be amended from time to time by a Specification
          Change Notice, a written agreement between the parties (each such
          Specification Change Notice being herein called an "SCN" and being
          substantially in the form of Exhibit "C" hereto). Each SCN will set
          forth in detail the particular changes to be made in the
          Specifications, and the effect, if any, of such changes on design,
          performance, weight, balance, time of delivery, Buyer Furnished
          Equipment and price (in base year dollars and, for information
          purposes only, in then current year dollars) 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 the Buyer and the Seller, but upon being so signed will
          constitute amendments to this Agreement. All SCNs will be signed on
          behalf of the Buyer by an officer in its finance department and an
          officer in flight operations or maintenance, or alternatively may be
          signed by the Buyer's chief executive officer or president.

3.2       Development Changes
          -------------------

          *** the Specifications may also be revised by the Seller without an
          SCN or the Buyer's consent solely to in corporate 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, weight,
          operational or maintenance requirements or performance of the Aircraft
          or adversely (i) change the interchangeability or replaceability
          requirements of the Specifications with respect to parts or (ii) ***

                   (hereinafter called "Development Changes"). ***


3.3       Requests and Approvals
          ----------------------

          In the event that the Buyer files a Request for Change ("RFC") with
          the Seller and the RFC does not subsequently become an SCN for any
          reason, such RFC will be cancelled without charge to the Buyer. Upon
          receipt of any request for a proposed change, the Seller will consider
          such request in good faith and will respond within ten (10) Working
          Days with (i) if possible, all

                                       12



<PAGE>




          appropriate information, including, a written estimated range of the
          cost thereof, the impact on the delivery dates of the applicable
          Aircraft and any certification requirements, or (ii) if (i) is not
          possible, with a date when the Seller will provide the Buyer with the
          information in (i). In the event that the Buyer requests the Seller in
          writing to incorporate a proposed change (excluding Development
          Changes) in an Aircraft and the Seller agrees to such request and
          incorporates such change, but the change is not subsequently made the
          subject of an SCN for any reason (other than the Seller's unreasonable
          refusal to sign the SCN or otherwise acting in bad faith), the Buyer
          will pay to the Seller the actual direct cost of design and other work
          resulting from such request and incurred by the Seller ***.

                      In the event that the Buyer requests the Seller in writing
          to proceed with a proposed change before any requisite approval of the
          LBA, for A319 Aircraft and A321 Aircraft, DGAC, for A320 Aircraft, and
          FAA has been obtained and subsequently such LBA, DGAC or FAA approval
          is not obtained, any SCN which will have been executed in connection
          with such proposed change will be deemed cancelled. ***


3.4       Specification Changes Before Delivery
          -------------------------------------

          If, pursuant to the promulgation, adoption, issuance, change or
          interpretation of any applicable law or regulation, any change in the
          Specifications has to be made before delivery of any Aircraft to
          enable ***.

                      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, Buyer Furnished Equipment and price
          of each Aircraft affected thereby and interchangeability or
          replaceability of parts. If the Seller 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 required by reason of such change, ***.


          The Seller will use all reasonable efforts to ensure that each
          Aircraft that is the subject of such postponement is "ready for
          delivery" without discrimination against the Aircraft.

                                       13

          ***

          The cost of the changes applicable to Propulsion Systems, will be
          borne by the Buyer or the manufacturer thereof in accordance with such
          arrangements as may be made separately between the Buyer and the
          manufacturer of the Propulsion Systems.

3.5       Specification Changes After Delivery
          ------------------------------------

          Subclause 3.4 will not require the Seller to make any changes or
          modifications to or to make any payments or take any other action with
          respect to any Aircraft delivered to the Buyer before any law or
          regulation referred to in Subclause 3.4 is to be complied with. Any
          such changes or modifications made to an Aircraft after its delivery
          to the Buyer will be at the Buyer's expense, except as otherwise
          agreed between the Buyer and the Seller.

3.6       Specification Evolution
          -----------------------

          The Seller will keep the Buyer advised of any evolution in the design
          of the A320 family of aircraft and of any new relevant option that
          becomes available with respect to the Aircraft.

          necessary) representatives of the Buyer during the aforementioned
          period.

7.1.3     All inspections, examinations and discussions with the Seller's, the
          Associated Contractors' or their respective subcontractors'
          engineering or other personnel by the Buyer and its said
          representatives will be performed in such manner as not to
          unreasonably delay or hinder the work to be carried out on the
          Aircraft or the proper performance of this Agreement.  In no event
          will the Buyer or its representatives be permitted to inspect any
          aircraft other than the Aircraft.  The Seller will not permit, and
          will cause the Manufacturer not to permit, any representatives,
          employees, agents or personnel of any other airline or customer to

          WHICH HAS BEEN ASSUMED BY THE OTHER PARTY PURSUANT TO THIS SUBCLAUSE
          7.2, THE FORMER (INDEMNITEE) WILL PROMPTLY GIVE NOTICE TO THE OTHER
          PARTY (INDEMNITOR), AND THE INDEMNITOR WILL HAVE THE RIGHT TO
          INVESTIGATE, AND THE RIGHT IN ITS SOLE DISCRETION TO ASSUME AND
          CONDUCT THE DEFENSE OF OR SETTLE OR COMPROMISE, SUCH CLAIM, ACTION,
          PROCEEDING OR LAWSUIT. HOWEVER, IF IN THE REASONABLE OPINION OF THE

          POTENTIAL IMPOSITION OF CRIMINAL LIABILITY ON THE INDEMNITEE OR A
          CONFLICT OF INTEREST BETWEEN THE INDEMNITOR AND THE INDEMNITEE, THE

          PARTICIPATION DOES NOT, IN THE REASONABLE OPINION OF INDEPENDENT
          COUNSEL OF THE INDEMNITOR, INTERFERE WITH THE CONDUCT OF SUCH DE
          FENSE. NOTWITHSTANDING ANYTHING TO THE CONTRARY, NO SETTLEMENT OR

          THE INDEMNITEE, WHICH CONSENT WILL NOT BE UNREASONABLY WITHHELD OR

8 -       BUYER'S ACCEPTANCE
          ------------------

8.1       Acceptance Procedures
          ---------------------

8.1.1     The Seller or any Affiliate thereof acting as the Seller's designee
          will give to the Buyer not less than thirty (30) days' notice of the
          proposed date and time when the  Buyer's acceptance tests will be
          conducted, and, in the event that the Buyer elects to attend the said
          tests, the Buyer will cooperate in complying with the reasonable
          requirements of the Seller with the intention of completing all tests
          within five (5) Working Days after commencement.  The tests will take
          place at  Daimler-Benz's works in Hamburg, Germany, for A319 Aircraft
          and A321 Aircraft, and at Aerospatiale's works near Toulouse, France,
          for A320 Aircraft, and will be carried out by the personnel of the
          Manufacturer (accompanied, if the Buyer so wishes, by representatives
          of the Buyer up to a total of six (6) (or more if reasonably requested
          by the Buyer) acting as observers, of whom not more than two (2) will
          have access to the cockpit at any one time and of whom one (1) may act
          as copilot, subject to such person's appropriate certification).
          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 three (3)
          hours, unless more time is necessary to complete the acceptance tests.

8.1.2     The Seller will cause ASC, at no cost to the Buyer, to brief, and
          provide one (1) free-of-charge four (4) hour simulator session for
          each new set of acceptance pilots. This briefing will provide specific
          information related to acceptance flights.

8.1.3     The acceptance tests will be designed to demonstrate the satisfactory
          functioning of the Aircraft and all systems relating thereto, and
          compliance with the terms, requirements and conditions of this
          Agreement, including conformity to the Specifications and ***.


                The successful completion of such acceptance tests will also be
          deemed to demonstrate compliance with the Specifications. The
          acceptance tests will be conducted in accordance with the
          Manufacturer's aircraft acceptance procedure, as amended to
          incorporate the Buyer's reasonable requests. At the time of delivery,
          the Aircraft will comply with all relevant limits and tolerances
          specified in the Aircraft Maintenance

                                       31



<PAGE>




          Manual. In the event that the Buyer does not attend the tests or fails
          to so cooperate, the Seller may complete them in the absence of the
          Buyer, provided that the Seller has given the Buyer reasonable prior
          written notice of not less than seven (7) days of its intention to
          complete such tests and the Buyer remains absent or uncooperative. The
          Buyer will be deemed to have accepted the tests, if such tests are
          reasonably deemed satisfactory by the Seller, and the Seller will
          furnish such data with respect to such tests as the Buyer may
          reasonably request. Notwithstanding the above, said acceptance by the
          Buyer will not impair the rights of the Buyer that derive from the
          warranties relating to the Aircraft.

8.1.4     If the acceptance tests for an Aircraft are not successfully completed
          or there is a defect, the Buyer, within two (2) days after such tests,
          will give notice to the Seller specifying such unsuccessful completion
          or defect.  Thereafter the Seller will, without unreasonable hindrance
          from the Buyer,  carry out any necessary changes and, as soon as
          practicable thereafter, resubmit the Aircraft for new acceptance
          tests, including flight tests if necessary, demonstrate the
          elimination of the defect, such tests to be held and carried out in
          accordance with this Subclause 8.1.  In order to avoid a delay in the
          delivery of any Air craft found to have one or more defects, the Buyer
          may elect with the consent of the Seller (such consent not to be
          unreasonably withheld) to take delivery of such Aircraft prior to the
          correction of such defects and without prejudice to any rights the
          Buyer may have under this Agreement against the Seller by reason of
          such defects.

          In the event the Buyer elects to take delivery of an Aircraft with
          defects pursuant to the preceding paragraph, delivery of such Aircraft
          will be made as originally scheduled, and such defects will be
          corrected, at the Seller's expense, by the Buyer or the Seller at such
          subsequent time as is mutually acceptable to the Buyer and the Seller,
          and as will be set forth in a written agreement that will state the
          settlement agreed by the Buyer and the Seller with respect to such
          defects.

8.1.5     Within three (3) months of execution of the Agreement, the Buyer and
          the Seller will review the technical documentation provided by the
          Seller at delivery of each Aircraft, and, if practicable, will agree
          on any reasonable changes to such documentation deemed necessary by
          the Buyer.

8.2       Seller's Use of Aircraft
          ------------------------

          The Seller will be entitled to use, without compensation to the Buyer,
          each Aircraft prior to its delivery as may be necessary to obtain the
          certificates required under Clause 2 hereof, and such use will not ***
          affect the Buyer's obligation to accept delivery

                                       32



<PAGE>




          of any Aircraft hereunder.  ***



8.3       Certificate of Acceptance
          -------------------------

          When the Aircraft is "ready for delivery" as defined below in
          Subclause 9.2, the Buyer will forthwith give to the Seller a signed
          Certificate of Acceptance in the form attached as Exhibit "E" in
          respect of the relevant Aircraft. Should the Buyer fail to so deliver
          the said Certificate, then the Buyer will be deemed to be in default
          as though it had without warrant rejected delivery of such Aircraft
          when duly tendered to it hereunder and will thereafter bear all costs
          and expenses resulting from such delay in delivery. The execution and
          delivery of a Certificate of Acceptance by the Buyer in respect of an
          Aircraft will not constitute waiver by the Buyer of any rights and
          remedies it may have in respect of any Aircraft under Clauses 12 and
          13 of this Agreement.

8.4       Finality of Acceptance
          ----------------------

          The Buyer's acceptance of delivery of each Aircraft will constitute
          waiver by the Buyer of any right it may have under the Uniform
          Commercial Code or otherwise to revoke such acceptance for any reason,
          whether known or unknown to the Buyer at the time of acceptance.

          deliver or otherwise in the performance of this Agreement or any part
          hereof due to causes reasonably beyond the Seller's, the
          Manufacturer's or any Associated Contractor's control or not
          occasioned by the Seller's, the Manufacturer's or any Associated
          Contractor's fault, misconduct or negligence ("Excusable Delay").

          It is expressly understood and agreed that each of (i) any delay
          caused directly or indirectly by the Buyer's failure to comply with
          its obligations hereunder, and (ii) any delay in delivery or otherwise
          in the performance of this Agreement by the Seller 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
          Equipment, will, to the extent attributable to such delay, constitute
          Excusable Delay for the Seller, unless such delay or failure of
          delivery or other event or circumstance is attributable to any default
          by the Seller of its obligations hereunder or any failure of the
          Seller to notify the Buyer and the manufacturer of the Propulsion
          Systems in a timely manner of the Seller's need therefor.

          The Seller will promptly after becoming aware of any delay falling
          within the provisions of this Subclause 10.1 (i) notify the Buyer of
          such delay and of the probable extent thereof, including, without
          limitation, a description of the cause thereof and, if possible, a
          possible date of rescheduled delivery in accordance with the terms of
          this Agreement, and after such prompt initial notice, apprise the
          Buyer of the status of such delay and possible date of such
          rescheduled delivery, and (ii) subject to the following provisions, as
          soon as practicable after the removal of the cause or causes for
          delay, resume the performance of those obligations affected under this
          Agreement. The Seller and the Manufacturer will endeavor to limit the
          extent of any such delay. The Seller will schedule the delivery of the
          Aircraft that is the subject of such delay to a date compatible with
          the Aircraft delivery schedule of the Buyer.

10.2      Unanticipated Delay
          -------------------

          In the event that the delivery of any Aircraft will be delayed by
          reason of an Excusable Delay for a period of more than twelve (12)
          months after the end of the calendar month in which delivery is
          otherwise required hereunder, the Buyer will be entitled to terminate
          this Agreement with respect only to the Aircraft so affected upon
          written notice given to the Seller within thirty (30)

          days after the expiration of such twelve (12) month period. In the
          event such delay will continue for an additional six (6) month period
          after the expiration of such twelve (12) month period, 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
          thirty (30) days after the end of such additional six (6) month
          period. Any termination of this Agreement in respect of an Aircraft
          pursuant to this Subclause 10.2 will discharge all obligations and
          liabilities of the parties hereunder with respect to such affected
          Aircraft, except that the Seller will repay to the Buyer, within three
          (3) Working Days of receipt of notice from the Buyer, an amount equal
          to the entire amount of any Predelivery Payments received from the
          Buyer hereunder with respect to such affected Aircraft, ***

10.3      Anticipated Delay
          -----------------

          In respect of any Aircraft, the Seller may conclude that Excusable
          Delays will (i) cause delay in delivery of such Aircraft for a period
          of more than twelve (12) 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, the Seller will give written notice to
          the Buyer of either (i) such delay and its related rescheduling
          reflecting such delay(s) or (ii) such nondelivery. Within thirty (30)
          days after the Buyer's receipt of such notice, the Buyer may terminate
          this Agreement as to such rescheduled or nondeliverable Aircraft by
          giving written notice to the Seller. Such termination will discharge
          all obligations and liabilities of the parties hereunder with respect
          to such affected Aircraft, except that the Seller will repay to the
          Buyer, within three (3) Working Days of the Buyer's giving notice to
          the Seller, an amount equal to the entire amount of any Predelivery
          Payment received from the Buyer hereunder with respect to such
          affected Aircraft, ***

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
          Subclause 10.3 (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, with a view towards
          having each Aircraft subject to such

          Excusable Delay ready for delivery as promptly as practicable.  ***


10.5      Lost, Destroyed or Damaged Aircraft
          -----------------------------------

          If any Aircraft suffers a total loss, is destroyed, or is damaged
          beyond economic repair prior to delivery thereof, then this Agreement
          will be terminated with respect to such Aircraft and the obligations
          and liabilities of the parties hereunder with respect to such Aircraft
          will be discharged. The Seller will repay to the Buyer an amount equal
          to the entire amount of any Predelivery Payments received from the
          Buyer hereunder with respect to any such Aircraft that is lost,
          destroyed or damaged beyond economic repair ***.

                and be covered by the warranty set forth in Subclause
                12.1.1(ii), and

<PAGE>




          repair, replacement or correction of, or the supply of modifications

          requested by the Buyer in writing and if reasonably practicable, make
          such correction in any affected Aircraft that has not already been
          delivered to the Buyer.  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

               bailee for hire, but the Seller will not be liable for loss of
               use, and (ii) title to and risk of loss of a returned component,

               any claim under this Subclause 12.1, on reasonable prior written

               part removed therefrom, which is claimed to be defective,
               returned to the Seller, as set forth in Subclause 12.1.6(i), if,
               in the judgment of the Seller, the nature of the defect requires

               obligations with labor unions, the Seller will further have the

               disassembly, inspection and testing of any Warranted Part claimed
               to be defective. Such representatives will not unreasonably
               interfere with the Buyer's operation and personnel.

         (iv)  In-house Warranty Claim Substantiation
               --------------------------------------

               Claims for In-house Warranty credit will be filed within the time
               period set forth in and will contain the same information
               required in Warranty Claims under Subclause 12.1.6(iv) and in
               addition, to the extent ascertainable, will include:

               (a)  a report of technical findings with respect to the defect,

               (b) for parts required to remedy the defect:

                    - part numbers,

                    - serial numbers (if applicable),

                    - description of the parts,

                    - quantity of parts,

                    - unit price of parts,

                    - total price of parts,

                      applicable),

               (c)  detailed number of labor hours,

               (d)  agreed In-house Warranty Labor Rate (defined below in
                    Subclause 12.1.7(v)(a)), and

               (e) total claim value.

         (v)   Credit
               ------

               The Buyer's sole remedy, and the Seller's sole obligation and
               liability, in respect of In-house Warranty claims, will be a
               credit to the Buyer's account. The credit to the Buyer's account
               will be equal to the direct labor cost expended in performing a
               repair and to the direct cost of materials associated with the
               repair. Such costs will be determined as set forth below.


               (a)  To determine direct labor costs, only man-hours spent on
                    disassembly, inspection, repair, reassembly, and final

                    necessary to complete a repair under the In-house Warranty)
                    of the Warranted Part will be counted. Man-hours required
                    for maintenance work concurrently being carried out on the
                    Aircraft or Warranted Part will not be included, ***



                    The man-hours counted as set forth above will be multiplied
                    by an agreed labor rate representing the Buyer's composite
                    average hourly labor rate (*** , including all ***
                              , social security charges, business taxes and
                    similar items, but excluding fringe benefits) paid to the
                    Buyer's employees whose jobs are directly related to the
                    performance of the repair (the "In-house Warranty Labor
                    Rate"). It is agreed that for the purpose hereof the In-
                    house Labor Rate is ***




               (b)  Direct material costs are determined by the prices at which
                    the Buyer acquired such replacement material, excluding any
                    parts and materials used for overhaul furnished free of
                    charge by the Seller.

         (vi)  Limitation on Credit
               --------------------

               The Buyer will in no event be credited for repair costs
               (including labor and material) for any Warranted Part exceeding
               sixty-five percent (65%) of the Seller's current catalog price
               for a replacement of such defective Warranted Part or exceeding
               those costs which would have resulted if repairs had been carried
               out at the Seller's facilities.

               Such cost will be substantiated in writing by the Seller upon
               reasonable request by the Buyer.

         (vii) Scrapped Material
               -----------------

               The Buyer will retain any Warranted Part defective beyond
               economic repair and any defective part removed from a Warranted
               Part during repair for a period of either one hundred and twenty
               (120) days after

               submission of a claim for In-house Warranty credit relating
               thereto, whichever is longer. Such parts will be returned to the
               Seller within thirty (30) days of receipt of the Seller's request
               to that effect, at the Seller's cost.

               Notwithstanding the foregoing, the Buyer may, with the agreement
               of the Seller's Field Representative, scrap any such defective
               parts that are beyond economic repair and not required for
               technical evaluation.

        (viii) LIMITATIONS ON LIABILITY OF SELLER
               ----------------------------------

               THE SELLER WILL NOT BE LIABLE FOR ANY RIGHT, CLAIM OR REMEDY, AND
               THE BUYER WILL INDEMNIFY THE SELLER AGAINST THE CLAIMS OF ANY
               THIRD PARTIES FOR ANY DEFECT, NONCONFORMANCE OR PROBLEM OF ANY
               KIND, ARISING OUT OF OR IN CONNECTION WITH ANY REPAIR OF
               WARRANTED PARTS OR ANY OTHER ACTIONS UNDERTAKEN BY THE BUYER

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

         The warranties provided for in this Subclause 12.1 for any Warranted
         Part will accrue to the benefit of any owner, lessor, lessee or
         operator other than the Buyer, if the Warranted Part enters into the
         possession of any such owner, lessor, lessee or operator as a result of
         a sale, transfer, lease or other conveyance or as a result of a pooling
         or leasing agreement between such owner, lessor, lessee or operator and
         the Buyer (and its successors and assigns), in accordance with the
         terms and subject to the limitations and exclusions of the foregoing
         warranties, and to applicable laws or regulations.

12.1.9   Warranty for Corrected, Replacement or Repaired Warranted Parts
         ---------------------------------------------------------------

         Whenever any Warranted Part that contains a defect for which the 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 replacement
         Warranted Part, whichever may be the case, will be ***
                           . 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

                                       62

          not be allowable, notwithstanding any subsequent correction or

                trademark, trade name, part or serial number or other
                identification marks have been removed.

          This limitation of the Seller's liability will apply in the cases of
          Subclause 12.1.10(i) and Subclause 12.1.10(ii) above only to the
          extent the Seller submits sufficient evidence proving that the defect
          arose from or was contributed to by either of said cases.

          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, normally covered under hull insurance
          policy.

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 twelve (12) 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 as hereinafter provided, either:

12.2.2.1  design and furnish to the Buyer a terminating 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), 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:

               ----------------
          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 since delivery of the particular Aircraft in
               which the Item subject to a Failure was originally installed, and

          N:   one hundred and forty-four (144) 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.

          (ii)  ***, the Buyer will keep the Seller informed of any significant
                incidents relating to an Aircraft, howsoever occurring or
                recorded.

          (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 and the Buyer. Such programs will be compatible
                with the Buyer's operational requirements and will be carried
                out at *** .

          (v)   In the case of any breakage or defect, *** , after any

                                       65



<PAGE>




                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, to the extent the Buyer has such
                information available.

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 will offer the necessary modification kit free of charge or
          under a prorata formula established by the Seller.  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, LIMITED TO THE AMOUNT THE

          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

          SUBCLAUSE 12.2 IN RESPECT OF SUCH CORRECTED OR REPLACEMENT ITEM.

          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.

12.3      VENDOR WARRANTIES
          -----------------

12.3.1    Seller's Support
          ----------------

          Prior to delivery of the first Aircraft, the Seller will obtain from
          all Vendors listed in the Supplier Product Support Agreements manual
          enforceable and transferable warranties, service life policies, and
          indemnities against patent infringements for Vendor Parts. The Seller
          will also obtain enforceable and transferable Vendor service life
          policies from landing gear Vendors for selected 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.

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 evidence
          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, the shorter of (i) the
          Vendor's warranty period as indicated in the Supplier Product Support
          Agreements manual and (ii) the Seller's warranty period as indicated
          in Subclause 12.1.3 of this Agreement will apply.

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
          evidence 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 "D" 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

                                       67



<PAGE>




          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, 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, 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. The Buyer
          will furnish to the Seller all data and information in the Buyer's
          possession relevant to the Interface Problem and will reasonably
          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 Interface Problem is attributable to the design of a Warranted
          Part, the Seller will, if requested by the Buyer, take prompt action
          to correct the design of such Warranted Part, pursuant to the terms
          and conditions of Subclause 12.1 or 12.2, as applicable.

12.4.3    Vendor's Responsibility
          -----------------------

          If the Interface Problem is 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, promptly
          assist and cooperate with the Buyer in processing and enforcing any
          warranty claim the Buyer may have against the manufacturer of such
          Vendor Component. Further, ***

12.4.4    Joint Responsibility
          --------------------

                                       68



<PAGE>




          If 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. When the Seller or any Vendor has performed such corrective
          action to the reasonable satisfaction of the Buyer, such correction
          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    All requests under this Subclause 12.4 will be directed to the Seller.

          a patent covered by Subclause 13.1, the Seller will as soon as
          practicable, after good faith consultation with the Buyer and at the
          Seller's expense, either (i) procure for the Buyer the right to use
          such part free of any liability for patent infringement or (ii) as

          ANY COURT ORDER OR SETTLEMENT TO INDEMNIFY IN WHOLE OR IN PART ANY
          THIRD PARTY FOR INJURY, LOSS OR DAMAGE INCURRED DIRECTLY OR INDIRECTLY
          AS A RESULT OF INCORPORATION OF ANY COC INTO THE TECHNICAL
          PUBLICATIONS ISSUED OR CAUSED TO BE ISSUED BY THE SELLER, THE BUYER

          BUYER IS PROVIDED AN OPPORTUNITY TO ASSUME THE DEFENSE AND/OR A
          SETTLEMENT OF SUCH CLAIM.  THIS INDEMNIFICATION BY THE BUYER WILL IN
          NO EVENT BE AFFECTED BY ANY WRITTEN OR ORAL COMMUNICATION THAT THE
          SELLER OR THE MANUFACTURER MAY MAKE TO THE BUYER IN RESPECT OF SUCH
          DOCUMENTATION.

16 -      TRAINING
          --------

16.1      Scope
          -----

          The Seller will provide or cause to be provided for the Buyer's
          personnel training described in this Clause 16 ("Training").

16.2      Course Organization and Administration
          --------------------------------------

16.2.1    Location and Scheduling
          -----------------------

          In general, Training will be held either at the Airbus Service Company
          Training Center, in Miami, Florida (the "ATC-Miami"), or at the Airbus
          Training Center in Toulouse, France (the "ATC-Toulouse"). Subject to
          availability of training slots at the time and at the selected
          location, the location of the Training will be at the Buyer's choice.
          The Seller will ensure that the Buyer's training plans (to be provided
          to the Seller reasonably in advance of the delivery of Aircraft) are
          implemented for a safe and smooth entry-into-service of the Aircraft.
          However, certain Training courses may also be held at the Buyer's base
          or other location, if practicable, under terms and conditions to be
          mutually agreed. The Buyer's training plans will include: (i)
          just-in-time (determined on a reasonable basis) training of flight
          crews, (ii) all necessary simulator time for regular transition
          courses, and (iii) aircraft experience for check pilots, and (iv)
          maintenance, dispatch and flight attendant training.

          Training courses will be scheduled for a minimum and maximum number of
          participants, at dates mutually agreed during a training conference to
          be held as soon as practicable (the "Training Conference").

16.2.2    Course Content
          --------------

          Training courses will include features of the Specifications required
          for training purposes, as known at the latest six (6) months before
          the first Training course starts. The Seller will endeavor to
          incorporate training features that become known after the six-month
          deadline. When the Seller does not provide maintenance or flight
          attendant training on the Seller's approved Buyer Furnished Equipment,
          the Seller will ensure that the Buyer gets the relevant training
          support from the supplier of the said equipment. Training courses will
          be FAA approved "Transition Courses." The Seller will provide the
          Buyer with A319/A320/A321 differences training for flight crew,
          maintenance, dispatch and/or flight attendant personnel.

          Training equipment used for flight and maintenance crew training will
          reflect

                                       90



<PAGE>




          the Specifications as closely as possible and will meet requirements
          to receive and maintain the relevant FAA course approval. Maintenance
          training will not assume prior knowledge of any Airbus aircraft. The
          Seller will be responsible for all Training course syllabi, training
          aids, equipment and materials.

16.2.3    Course Guidelines
          -----------------

          Courses are designed and approved to bring jet transport specialists
          to a professional knowledge of the Aircraft and satisfy FAA
          requirements for training and checking. The Seller will use reasonable
          efforts to satisfy the Buyer's requirements and policies regarding
          training.

          In addition:

          (i)   Training will be conducted in English, and all training
                materials are written in English using common aeronautical
                terminology.

          (ii)  Pilot trainees will have the prerequisite jet transport category
                experience defined in Appendix "A" to this Clause 16.

          (iii) Avionics courses (listed in Appendix "B" to this Clause 16) are
                designed for avionics specialists knowledgeable of ARINC 429
                liaisons.

          (iv)  The Buyer will give the Seller a list of trainees enrolling in
                each Training course.

          (v)   The Seller will not be liable for the unsatisfactory performance
                of individual trainees for any reason solely and directly
                outside the Seller's control.

          (vi)  The Seller will consult with the Buyer if the Seller finds that
                a trainee lacks entry-level knowledge. After such consultation,
                the trainee will either be cycled through an entry-level
                training program or be withdrawn from the Training course. All
                costs associated with such entry-level program and with the
                cancellation of the scheduled transition training will be
                charged to the Buyer's account.

          (vii) The Seller will give all trainees who satisfactorily complete
                Training courses a certificate of completion including the
                instructor's name and identification number. This certificate
                will not represent authority or qualification by any official
                civil aviation authority, although it may be presented to such
                authority as an attestation of completion of the Seller's
                training courses.

                                       91



<PAGE>




          (viii) An extension in duration, a repetition or a deviation from the
                 standard of any course to be given or in progress (for reasons
                 due to the Buyer, including, but not limited to, unsatisfactory
                 performance of the trainees) will be provided on the Buyer's
                 request and/or on the Seller's advice and subject to mutual
                 agreement. ***




16.2.4    Additional Training
          -------------------

          Besides the free-of-charge Training courses provided pursuant to
          Subclause 16.3, the Seller will offer additional training courses and
          training services at the Buyer's expense, subject to availability.

16.2.5    Training at the Buyer's Base
          ----------------------------

16.2.5.1  At the Buyer's request, and if practicable, the Training will be
          provided by the Seller's instructors at any location other than ATC-
          Miami or ATC-Toulouse. ***



          The Buyer may provide the Seller with air travel for the Seller's
          instructors to and from ATC-Miami or ATC-Toulouse, as applicable, and
          the place of assignment.

16.2.5.2  The Training equipment necessary for course performance on the Buyer's
          request at any location other than ATC-Miami or ATC-Toulouse will be
          provided by the Buyer in accordance with the Seller's specifications.
          In the event the Buyer cannot make available the relevant equipment,
          the Seller will use reasonable efforts to provide this equipment and
          send it  by air from Miami, Florida, or Toulouse, France, to the
          course location and back to Miami, Florida, or Toulouse, France,  at
          the Buyer's expense.

16.2.6    Practical Training on Aircraft
          ------------------------------

16.2.6.1  ***

16.2.6.2  Any *** Flight Crew Training involving the use of an aircraft will be

          (i)  the Seller will help the Buyer find a substitute aircraft, and

          (ii)  ***.

          When on-aircraft Flight Crew Training is performed at ATC-Toulouse,
          the Seller will provide free-of-charge line maintenance, including
          servicing, preflight checks and changing of minor components for the
          contractual training sessions. In the case that the training is
          performed on the Buyer's aircraft, the Buyer will provide a mutually
          agreed batch of spare parts as required to support said training and
          will bear all other expenses such as fuel, oil and landing fees. In
          the event that the Seller is not able to provide sufficient simulator
          time to train the Buyer's crews, and it becomes necessary to use the
          Aircraft instead, the Seller will compensate the Buyer US$ *** (US
          dollars--*** ) (in 1996 dollars) per flight hour.

          Finally, the Buyer will meet the requirement for a certificate of
          insurance set forth below in Subclause 16.6.5.

     --------

     The Seller recommends that captains have a minimum of 1,000 hours'
     experience in command of jet transport category aircraft prior to

     minimum described above in Paragraph 1 will be considered for transition
     training provided under Clause 16 of this Agreement on a case-by-case.

3.   CO-PILOTS
     ---------

     operating transport aircraft, of which at least 300 hours' should be with
     jet transport aircraft. This recommended minimum includes formal basic

     who do not have jet transport experience, the Seller recommends its "Jet
     Familiarization Course."

          delivered to the Manufacturer to permit installation in and delivery
          of such Aircraft in accordance with the delivery schedule referred to
          in Clause 9.  The Buyer will furnish such equipment to the
          Manufacturer at such locations by such dates.  The Buyer, 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 requested by

          and calibrating Buyer Furnished Equipment to the extent necessary to
          obtain LBA, DGAC and FAA approval, unless such adjusting and
          calibrating is made necessary by improper installation by the Seller
          of the Buyer Furnished Equipment.

          (ii) cause the Final Contract Price of the Aircraft to be increased by
               the amount of the Seller's reasonable additional costs, if any,

          than thirty (30) days after the date specified by the Manufacturer for

          A320 Aircraft, or FAA within thirty (30) days after the date specified
          by the Manufacturer for the delivery of such Buyer Furnished
          Equipment, then the Seller will be entitled to deliver the Aircraft
          with no obligation to install such Buyer Furnished Equipment. The
          Buyer may also elect to have the Aircraft so delivered, whereupon the
          Seller will be relieved of all obligations to install such Buyer

18.4      Tax-Free Zones
          --------------

          The Buyer will cause all Buyer Furnished Equipment to be delivered at

          directly certain items that are considered Buyer Furnished Equipment
          pursuant to the Specifications, and if compliance with such request by
          the Seller and the Manufacturer in their judgment will not affect the

          the effect on price and any other items and conditions of this

22.4      Confidentiality
          ---------------

          Subject to any legal or governmental requirements of disclosure, the
          parties (which for this purpose will include their employees, agents
          and advisors) will maintain the terms and conditions of this
          Agreement, any reports or other data furnished, and other documents
          furnished by the Seller hereunder strictly confidential. Without
          limiting the generality of the foregoing, each party will use its best
          efforts to limit the disclosure of the contents of this Agreement to
          the extent legally permissible in any filing required to be made by it
          with any governmental agency and will make such applications as will
          be necessary

          filing, the disclosing party agrees to submit to the other party a
          copy of the proposed document to be filed or disclosed and will give
          the other party a reasonable period of time in which to review the
          said document. The Buyer and the Seller will consult with each other
          prior to the making of any public disclosure or filing, permitted
          hereunder, of this Agreement or the terms and conditions thereof. The
          provisions of this Subclause 22.4 will survive any termination of this
          Agreement.

22.5      Severability
          ------------

          In the event that any provision of this Agreement should for any
          reason be held to be without effect, the remainder of this Agreement
          will remain in full force and effect. To the extent permitted by
          applicable law, each party hereto hereby waives any provision of law
          which renders any provision of this Agreement prohibited or
          unenforceable in any respect.

          other Exhibit or Letter Agreement attached to this Agreement, in each
          such case the terms of such Specifications, Exhibit or Letter
          Agreement will prevail over the terms of this Agreement. For the
          purpose of this Subclause 22.7, the term Agreement will not include

                             CONSENT AND GUARANTY
                             --------------------

          Airbus Industrie, G.I.E., established under "Ordonnance" No. 67-821
dated September 23, 1967, of the Republic of France (the "Guarantor"), hereby
acknowledges notice of and consents to all of the terms of the Airbus
A319/A320/A321 Purchase Agreement dated as of October 31, 1997 (as amended,
modified, or supplemented from time to time, the "Agreement"), between AVSA,
S.A.R.L. (the "Seller"), and US Airways Group, Inc. (the "Buyer"), including,
without limitation, the assignments of the Seller's rights under its agreements
with the Guarantor, contained in Clauses 12 and 13, Letter Agreements Nos. 1,
8A, 8B, 8C, 9, 10, 12 and 13 of such Agreement, and hereby irrevocably and
unconditionally guarantees the due and punctual payment and performance by the
Seller of all of the latter's liabilities and obligations as set forth in the
said Agreement subject to the terms and limitations therein contained. The
Guarantor hereby agrees that its obligations hereunder will be unconditional and
absolute and, without limiting the generality of the foregoing, will not be
released, discharged or otherwise affected by (i) any modification or amendment
of or supplement to said Agreement (other than release, discharge or waiver of
this guarantee hereunder) or (ii) any assignment of said Agreement or of any
rights or obligations thereunder made in accordance with Clause 19 thereof. The
Guarantor further agrees that it will execute and deliver such other and further
instruments as may be reasonably requested by the Buyer (as such term is defined
in the said Agreement), its successors or assigns to reaffirm its obligations
hereunder. This Consent and Guaranty constitutes a guaranty of performance and
of payment, and the Guarantor agrees that, in case of default by the Seller, the
Buyer will not be required to file suit against the Seller as a condition to
enforcement of this Consent and Guaranty.

          The Guarantor irrevocably agrees that any legal action or proceeding
against the Guarantor with respect to this Consent and Guaranty may be brought
and determined in the Supreme Court of the State of New York, New York County,
in the General District Courts of Fairfax County or Arlington County, Virginia,
in the United States District Courts for the Southern District of New York or
the Eastern District of Virginia, or in the commercial Court ("Tribunal de
Commerce") of Toulouse, France, and irrevocably accepts with regard to any such
action or proceeding the nonexclusive jurisdiction of those courts. The
Guarantor irrevocably waives the benefit of Articles 14 and 15 of the French
Civil Code. The Guarantor hereby irrevocably waives, and agrees not to assert,
the defense of sovereign immunity, and, to the extent permitted by law, the
defense that the action or proceeding is brought in an inconvenient forum, that
the venue of the action or proceeding is improper, or that this Consent and
Guaranty may not be enforced in or by such courts. However, the preceding
sentence will not be construed as a waiver of any requirement of service of
process. The Guarantor hereby irrevocably designates CT Corporation as the
Guarantor's agent to receive service of process in any legal action or
proceeding with respect to this Consent and Guaranty.

                                LICENSE FOR USE
                                ---------------
                 OF THE PERFORMANCE ENGINEERING PROGRAMS (PEP)
                 ---------------------------------------------

1.   GRANT
     -----

     The Seller grants to the Buyer the right to use the Performance Engineering
     Programs (PEP) in machine readable form on a single computer during the
     term of this license agreement (the "License Agreement").

     Use of the PEP in readable form will be limited to one (1) copy. However,
     the Seller may make duplicate copies, provided that they are either
     contained in the same computer as the original copy, or produced for
     checkpoint and restart purposes or made with the consent of the Seller for
     a specific need.

2.   MERGER
     ------

     The PEP may be used and adapted in machine readable form for the purpose of
     merging it into other program material of the Buyer, but, on termination of
     this License Agreement, the Buyer will remove the PEP from the other
     program material with which it has been merged.

     The Buyer agrees to reproduce the copyright and other notices as they
     appear on or within the original media on any copies that the Buyer makes
     of the PEP.

3.   PERSONAL LICENSE
     ----------------

     The above described license is personal to the Buyer, nontransferable and
     nonexclusive.

4.   INSTALLATION
     ------------

     It is the Buyer's responsibility to install the PEP and to perform any
     mergings and checks. The Seller will, however, assist the Buyer's
     operations engineers in the initial phase following the delivery of the PEP
     until such personnel reach the familiarization level required to make
     inputs and correlate outputs.

5.   PROPRIETARY RIGHTS AND NONDISCLOSURE
     ------------------------------------

5.1  The PEP and the copyright and other proprietary rights of whatever nature
     in the PEP are and will remain with the Seller. The PEP and its contents
     are designated as confidential.

5.2  The Buyer undertakes not to disclose the PEP, parts thereof or its contents
     to any third party without the prior written consent of the Seller. Insofar
     as it is necessary to disclose aspects of the PEP to employees, such
     disclosure is permitted only for the purpose for which the PEP is supplied
     and only to the employee who needs to know the same.

6.   CONDITIONS OF USE
     -----------------



<PAGE>



6.1  The Seller does not warrant that the PEP will contain no errors. However,
     should the PEP be found to contain any error at delivery, the Buyer will
     notify the Seller promptly thereof and the Seller will take all proper
     steps to correct the same at its own expense.

6.2  The Buyer will ensure that the PEP is correctly used in appropriate
     machines as indicated in the Performance Programs Manual (PPM) and that
     staff are properly trained to use the same, to trace and correct running
     faults, to restart and recover after fault and to operate suitable checks
     for accuracy of input and output.

6.3  It is understood that the PPM is the user's guide of the PEP and that the
     Buyer will undertake to use the PEP in accordance with the PPM.

6.4  The PEP is supplied under the express condition that the Seller will have
     no liability in contract or in tort arising from or in connection with the
     Buyer's use of or inability to use the PEP.

7.   DURATION
     --------

     Subject to the Buyer's compliance with the terms of this License Agreement,
     the rights under this License Agreement will be granted to the Buyer for as
     long as the Buyer operates an Aircraft to which the PEP refers.

l.       BASE PRICE
         ----------

         The Base Price of the Airframe is as quoted in Subclause 4.1.1.1,
         4.1.1.2 or 4.1.1.3 of the Agreement, as applicable.

         The Base Price of a set of two (2) nacelles and two (2) thrust
         reversers is as quoted in Subclause 4.1.2.1.1(ii), 4.1.2.2.1(ii), or
         4.1.2.3.1(ii) of the Agreement, as applicable.

2.       BASE PERIOD
         -----------

         ***





         These Base Prices are subject to adjustment for changes in economic
         conditions as measured by data obtained from the United States
         Department of Labor, Bureau of Labor Statistics, and in accordance with
         the provisions of Paragraphs 4 and 5 of this Exhibit "G."

         ECIb and ICb index values indicated in Paragraph 4 of this Exhibit "G"
         are based on publications available at the date of signature of the
         Agreement and are United States Department of Labor Bureau of Labor
         Statistics computations corresponding to certain base years as
         stipulated below in Paragraph 3. Should the Bureau of Labor Statistics
         change such base year, it will be necessary to restate such values in
         an appropriate manner. Other changes (such as benchmark revision),
         except those related to established errors from the Bureau of Labor
         Statistics, will not be taken into consideration.

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

         ***







         In determining the Revised Base Price at delivery of the Aircraft, each
         quotient will be calculated to the nearest ten thousandth (4 decimals).
         If the next succeeding place is five (5) or more, the preceding decimal
         place will be raised to the next higher figure. The final factor will
         be rounded to the nearest ten thousandth (4 decimals).

         After final computation, Pn will be rounded to the next whole number
         (0.5 or more rounded to l).


5.       GENERAL PROVISIONS
         ------------------

5.1      Substitution of Indexes
         -----------------------

         In the event that:

         (i)      the United States Department of Labor substantially
                  revises its methodology for calculating any of the
                  indexes referred to hereabove, or

         (ii)     the United States Department of Labor discontinues, either
                  temporarily or permanently, any of the indexes referred to
                  hereabove and publication thereof, or

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

         The Seller and the Buyer will agree on a substitute index.

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

         As a result of this selection of a substitute index, the Seller and the
         Buyer will agree on appropriate adjustments to be made to the price
         revision formula; such adjustments may include, but will not be limited
         to, allowing to combine the successive utilization of the original
         index and of the substitute index, and other methodologies designed to
         ensure consistency in the numerators and denominators of the various
         quotients.

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, to the
         applicable indexes as published at the date of Aircraft delivery.

5.1      The Revised Reference Price at delivery of the Aircraft will 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 United States Department of Labor substantially revises
         the methodology of calculation of the indexes referred to in
         this Exhibit "H-1" or discontinues any of these indexes, the
         Seller will, 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 will be made to accomplish this
         result.

5.4      Should the above escalation provisions become null and void by action
         of the United States Government, the Reference Price will 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
         Aircraft.

5.5      The Revised Reference Price at delivery of the Aircraft in no event
         will be less than the Reference Price defined in Paragraph 1 of this

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

         Pb       =        Reference Price as defined above.

                           the month of delivery of the Aircraft.

                           Said Composite Price Index is composed as follows:

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

                  Where

         HEn               = HE SIC 3724 for the sixth month prior to the month
                           of delivery of the 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

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

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

5.       GENERAL PROVISIONS
         ------------------

5.1      The Revised Reference Price at delivery of the Aircraft will 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 United States Department of Labor substantially revises the
         methodology of calculation of the indexes referred to in this Exhibit
         "H-3" or discontinues any of these indexes, the Seller will, 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 will be made to accomplish this
         result.

5.4      Should the above escalation provisions become null and void by action
         of the United States Government, the Reference Price will 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
         Aircraft.

5.5      The Revised Reference Price at delivery of the Aircraft in no event
         will be less than the Reference Price defined in Paragraph 1 of this
         Exhibit "H-3."

                  transportation *** at no charge to the Seller, *** The
                  Seller, in addition, will use its best efforts to cause

          "A" to this Paragraph 12 ("Leased Parts") and will form a part of each
          lease of any Leased Part by the



<PAGE>




          Buyer from the Seller after the date hereof. Except for the
          description of the Leased Part, the Lease Term, the Leased Part
          delivery and return locations and the Lease Charges (defined below in
          Subparagraph 12.4), all other terms and conditions appearing on any
          order form or other document pertaining to Leased Parts will be deemed
          inapplicable, and in lieu thereof the terms and conditions of this
          Paragraph 12 will prevail. For purposes of this Paragraph 12, the term
          "Lessor" refers to the Seller and the term "Lessee" refers to the
          Buyer. Parts not included in Appendix "A" to this Paragraph 12 may be
          supplied under a separate lease agreement between the Seller and the
          Buyer.

12.2      Lease Procedure: Spare Parts Leased
          -----------------------------------

          At the Lessee's request by telephone (to be confirmed promptly in
          writing), telegram, letter or other written instrument, the Lessor
          will lease Leased Parts, which will be made available in accordance
          with Subparagraph 4.2.3 of this Letter Agreement, to the Lessee as
          substitutes for parts withdrawn from an Aircraft for repair or
          overhaul. Each lease of Leased Parts will be evidenced by a lease
          document ("Lease") issued by the Lessor to the Lessee no later than
          seven (7) days after delivery of the Leased Part.

12.3      Lease Term: Return
          ------------------

          The term of the lease ("Lease Term") will commence on the date of
          receipt of the Leased Part by the Lessee or its agent at the Lessee's
          facility in a serviceable condition and will end on the date of
          receipt at the Lessor's facility of the Leased Part in a serviceable
          condition. The Lease Term will not exceed ninety (90) days after the
          Lessee's receipt of the Leased Part, unless extended by written
          agreement between Lessor and Lessee within such ninety (90)-day period
          (such extension not to exceed an additional ninety (90) days).
          Notwithstanding the foregoing, the Lease Term will end in the event,
          and upon the date, of exercise of the Lessee's option to purchase the
          Leased Part, as provided herein.

12.4      Lease Charges and Taxes
          -----------------------

          The Lessee will pay the Lessor (a) a daily rental charge for the Lease
          Term in respect of each Leased Part equal to one-three-hundred-sixty-
          fifth (1/365) of the Catalog Price of such Leased Part, as set forth
          in the Seller's Spare Parts Price List in effect on the date of
          commencement of the Lease Term, (b) any reasonable additional costs
          which may be incurred by the Lessor solely and directly as a result of
          such Lease, such as inspection, test, repair, overhaul and repackaging
          costs as required to place the Leased Part in serviceable condition,
          (c) all transportation and insurance charges and (d) any taxes
          (excluding any taxes based on income or gross receipts), charges or
          customs duties imposed upon the Lessor or its property as a result of
          the lease, sale, delivery, storage or transfer of any



<PAGE>




          Leased Part (the "Lease Charges"). All payments due hereunder will be
          made in accordance with Paragraph 6 of this Letter Agreement.

          In the event that the Leased Part has not been returned to the
          Lessor's designated facilities within the time period provided in
          Subparagraph 12.3 above, the Lessor will be entitled, in addition to
          any other remedy it may have at law or under this Paragraph 12, to
          charge to the Lessee, and the Lessee will pay, all of the charges
          referred to in this Subparagraph 12.4 accruing for each day after the
          end of the Lease Term and for as long as such Leased Part is not
          returned to the Lessor and as though the Lease Term were extended to
          the period of such delay.

          Notwithstanding the foregoing, the Lessor hereby agrees not to charge
          the Lessee any daily rental charge as referred to above in
          Subparagraph 12.4(a) from the date that is ninety (90) days after the
          date of receipt of the Leased Part by the Lessee, provided that (i)
          the Lessee reasonably demonstrates that the repair station designated
          by the Lessor and to which the Lessee has sent the damaged item (which
          is the cause of the lease described in this Paragraph 12) (the
          "Damaged Item") has failed to perform the repair of the Damaged Item
          within ninety (90) days, and (ii) the repair station is unable to
          provide adequate and satisfactory reasons for its nonperformance.

12.5      Title
          -----

          Title to each Leased Part will remain with the Lessor at all times
          unless the Lessee exercises its option to purchase or exchange it in
          accordance with Subparagraph 12.8 of this Letter Agreement, in which
          case title will pass to the Lessee in accordance with Paragraph 7 of
          this Letter Agreement.

12.6      Risk of Loss
          ------------

          Except for normal wear and tear, each Leased Part will be returned to
          the Lessor in the same condition as when delivered to the Lessee.
          However, the Lessee will not without the Lessor's prior written
          consent repair, modify or alter any Leased Part (other than routine
          maintenance). Risk of loss or damage to each Leased Part will remain
          with the Lessee until such Leased Part is redelivered to the Lessor at
          the return location specified in the applicable Lease. If a Leased
          Part is lost or damaged beyond repair, the Lessee will be deemed to
          have exercised its option to purchase the part in accordance with
          Subparagraph 12.8 of this Letter Agreement, as of the date of such
          loss or damage.

12.7      Record of Flight Hours
          ----------------------

          All flight hours accumulated by the Lessee on each Leased Part during
          the Lease Term will be documented by the Lessee. Records will be
          delivered to the Lessor upon return of such Leased Part to the Lessor.
          In addition, all documentation pertinent to inspection, maintenance
          and/or rework of the Leased Part to maintain said Leased Part
          serviceable in accordance with the standards of the Lessor will be
          delivered to the Lessor upon return of the Leased Part to the Lessor
          on



<PAGE>




          termination of the Lease.

          Such documentation will include but not be limited to evidence of
          incidents such as hard landings, abnormalities of operation and
          corrective action taken by the Lessee as a result of such incidents.

12.8      Option to Purchase
          ------------------

          The Lessee may at its option, exercisable by written notice given to
          the Lessor, elect during or at the end of the Lease Term to purchase
          the Leased Part, in which case the then current purchase price for
          such Leased Part as set forth in the Seller's Spare Parts Price List
          will be paid by the Lessee to the Lessor. The immediately preceding
          sentence will apply to new Leased Parts only. In the event the Leased
          Part is not new at commencement of the Lease Term, eighty-five percent
          (85%) of the then current purchase price for such Leased Part will be
          paid by the Lessee to the Lessor. Such option will be contingent upon
          the Lessee providing the Lessor with evidence satisfactory to the
          Lessor that the original part fitted to the Aircraft is beyond
          economical repair. Should the Lessee exercise such option, *** (*** )
          of the Lease rental charges already invoiced pursuant to Subparagraph
          12.4 (a) will be credited to the Lessee against the said purchase
          price of the Leased Part.

          Should the Lessee fail to return the Leased Part to the Lessor at the
          end of the Lease Term, such failure will be deemed to be an election
          by the Lessee to purchase the Leased Part.

          In the event of purchase, the Leased Part will be warranted in
          accordance with Clause 11 of this Letter Agreement as though such
          Leased Part were a Seller Part, provided, however, that (i) the Seller
          will prorate the full Warranty Period granted to the Buyer according
          to the actual usage of such Leased Part and (ii) in no event will such
          Warranty Period be less than six (6) months from the date of purchase
          of such Leased Part. A warranty granted under this Subparagraph 12.8.3
          will be in substitution for the warranty granted under Subparagraph
          12.9 at the commencement of the Lease Term.

12.9      Warranties
          ----------

          The Lessor, in its capacity as "Lessee," under its arrangements with
          the Manufacturer, in its capacity as "Lessor," has negotiated and
          obtained the following warranties from the Manufacturer with respect
          to the Leased Parts, subject to the terms, conditions, limitations and
          restrictions all as hereinafter set out. The Lessor hereby assigns to
          the Lessee, and the Lessee hereby accepts, all of the rights and
          obligations of the Lessor in the Lessor's capacity as "Lessee" as
          aforesaid under the said warranties and the Lessor subrogates the
          Lessee as to all such rights and obligations in respect of Leased
          Parts during the Lease Term with respect thereto. The Lessor hereby
          warrants to the Lessee that the Lessor has all requisite authority to
          make the foregoing assignment and effect the foregoing



<PAGE>




          subrogation to and in favor of the Lessee and that the Lessor will not
          enter into any amendment of the provisions so assigned or subrogated
          without the prior written consent of the Lessee. Capitalized terms
          utilized in the following provisions have the meanings assigned
          thereto in this Letter Agreement, except that the term "Lessor" refers
          to the Manufacturer and the term "Lessee" refers to the Lessor.
          References to clauses and paragraphs in the following provisions refer
          to clauses in the Agreement and/or to paragraphs in this Letter
          Agreement.

QUOTE

12.9.1    The Lessor warrants that each Leased Part will at the time of delivery
          thereof:

          (a)  be free from defects in material,

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

          (c)  conform to the applicable specification for such part,

          (d)  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,

          (e)  permit complete interchangeability among Aircraft and parts of
               like part-numbered parts, and

          (f) be free and clear of all liens and other encumbrances.

12.9.2    Survival of Warranties
          ----------------------

          With respect to each Leased Part, the warranty set forth above in
          Subparagraph 12.9.1(a) will not survive delivery, and the warranties
          set forth above in Subparagraphs 12.9.1(b) through 12.9.1(f) will
          survive delivery only upon the conditions and subject to the
          limitations set forth below in Subparagraphs 12.9.3 through 12.9.8.

12.9.3    Warranty and Notice Periods
          ---------------------------

          The Lessee's remedy and the Lessor's obligation and liability under
          this Subparagraph 12.9, with respect to each defect, are conditioned
          upon (i) the defect having become apparent within the Lease Term and
          (ii) the Lessor's warranty administrator having received written
          notice of the defect from the Lessee within ***



<PAGE>




12.9.4    Return and Proof
          ----------------

          The Lessee's remedy and the Lessor's obligation and liability under
          this Subparagraph 12.9, with respect to each defect, are also
          conditioned upon:

          (a)  the return by the Lessee as soon as practicable to the return
               location specified in the applicable Lease, or such other place
               as may be mutually agreeable, of the Leased Part claimed to be
               defective, and

          (b)  the submission by the Lessee to the Lessor's warranty
               administrator of reasonable proof that the claimed defect is due
               to a matter embraced within the Lessor's warranty under this
               Subparagraph 12.9 and that such defect did not result from any
               act or omission of the Lessee, including but not limited to any
               failure to operate or maintain the Leased Part claimed to be
               defective or the Aircraft in which it was installed in accordance
               with the Lessee's FAA-approved maintenance program.

12.9.5    Remedies
          --------

          The Lessee's remedy and the Lessor's obligation and liability under
          this Subparagraph 12.9 with respect to each defect are limited to the
          repair of such defect in the Leased Part in which the defect appears,
          or, as mutually agreed, to the replacement of such Leased Part with a
          similar part free from defect.

          Any replacement part furnished under this Subparagraph 12.9.5 will for
          the purposes of this Letter Agreement be deemed to be the Leased Part
          so replaced.

12.9.6    Suspension and Transportation Costs
          -----------------------------------

12.9.6.1  If a Leased Part is found to be defective and is covered by this
          warranty, the Lease Term and the Lessee's obligation to pay rental
          charges as provided in Subparagraph 12.4(a) of this Letter Agreement
          will be suspended from the date on which the Lessee notifies the
          Lessor of such defect until the date on which the Lessor has repaired,
          corrected or replaced the defective Leased Part, provided, however,
          that the Lessee has withdrawn such defective Leased Part from use,
          promptly after giving such notice to the Lessor.  If the defective
          Leased Part is replaced, such replacement will be deemed to no longer
          be a Leased Part under the Lease as of the date on which such part was
          received by the Lessor at the return location specified in the
          applicable Lease.

          If a Leased Part is found to be defective on first use by the Lessee
          and is covered by this warranty, no rental or other charges as
          provided in Subparagraph 12.4(a) will accrue and be payable by the
          Lessee until the date on which the Lessor has repaired, corrected or
          replaced the defective Leased Part in a manner satisfactory to the
          Lessee.

12.9.6.2  All transportation and insurance costs associated with the return of
          the defective



<PAGE>




          Leased Part to the Lessor and the return of the repaired, corrected or
          replacement part to the Lessee will be borne by the Lessor.

12.9.7    Wear and Tear
          -------------

          Normal wear and tear and the need for regular maintenance and overhaul
          will not constitute a defect or nonconformance under this Subparagraph
          12.9.

12.9.8    Exclusivity of Warranties and General Limitations of Liability
          --------------------------------------------------------------
          and Duplicate Remedies
          ----------------------

          The Lessee and the Lessor recognize and agree that the Exclusivity of
          Warranties and General Limitations of Liability provisions and the
          Duplicate Remedies provisions contained in Clause 12 of the Agreement
          will also apply to the foregoing warranties provided for in this
          Subparagraph 12.9.

Ladies and Gentlemen:

     US Airways Group, Inc. (the "Buyer"), and AVSA, S.A.R.L. (the "Seller"),

     Both parties agree that this Letter Agreement will constitute an integral,

2.   RECONFIRMABLE AIRCRAFT
     ----------------------

     In order to provide the Buyer with flexibility to meet its future fleet mix
     requirements, the Seller grants the Buyer the right to reconfirm its order
     for each and any Reconfirmable Aircraft. The Buyer will notify the Seller
     in writing by no later than *** (*** ) *** before the scheduled month of
     delivery of a Reconfirmable Aircraft as to whether it reconfirms the order
     for the applicable Reconfirmable Aircraft.

          Upon such nonreconfirmation, the Buyer's rights with respect to the
     Reconfirmable Aircraft that was not reconfirmed will expire and the parties

     Reconfirmable Aircraft.

1.   CONVERSION RIGHT
     ----------------

1.1  In order to provide the Buyer with additional flexibility to meet its
     future fleet mix requirements, the Seller grants the Buyer aircraft type
     conversion rights under the terms and conditions contained in this
     Paragraph 1 (the "Conversion Right").

     ***

     (iii)  The Conversion Right will be subject to the Manufacturer's
            Commercial Constraints and Industrial Constraints at the time the
            Buyer elects to exercise its Conversion Right.

1.2  The Buyer's exercise of its Conversion Right with respect to a particular
     Aircraft will result in an adjustment to the Predelivery Payment Reference
     Price and Predelivery Payments due in respect of the converted Aircraft (a
     "Converted Aircraft").

     If the Predelivery Payment Reference Price for a Converted Aircraft is
     higher than it was for the Aircraft from which it was converted (the
     "Original Aircraft"), then the difference between the Predelivery Payments
     the Buyer has paid and what it would have paid had the Converted Aircraft
     been an Original Aircraft will be due within three (3) Working Days of
     conversion, and conversion will be effective when the Buyer pays such
     difference.

Ladies and Gentlemen:

     US Airways Group, Inc. (the "Buyer"), and AVSA, S.A.R.L. (the "Seller"),
have entered into an Airbus A319/A320/A321 Purchase Agreement dated as of even
date herewith (the "Agreement"), which covers, among other things, the sale by

     Both parties agree that this Letter Agreement will constitute an integral,
nonseverable part of said Agreement, that the provisions of said Agreement are
hereby incorporated herein by reference, and that this Letter Agreement will be
governed by the provisions of said Agreement, except that if the Agreement and
this Letter Agreement have specific provisions which are inconsistent, the
specific provisions contained in this Letter Agreement will govern.



<PAGE>




     The Seller, under its arrangement with the Manufacturer, has negotiated and
obtained the following Technical Dispatch Reliability Guarantee from the
Manufacturer with respect to the Aircraft, subject to the terms, conditions,
limitations and restrictions all as hereinafter set out. The Seller hereby
guarantees to the Buyer the performance by the Manufacturer of its obligations

and not otherwise defined therein will have the meanings assigned thereto in the
Agreement, except that the term "Seller" refers to the Manufacturer and the term
"Buyer" refers to the Seller.

     QUOTE

1.   SCOPE, COMMENCEMENT, DURATION
     -----------------------------

     This dispatch reliability guarantee (the "Guarantee") extends to the
     Aircraft fleet, will commence with delivery of the first Aircraft and will
     remain in force for a period of *** years (the "Term"), ***


2.   DEFINITION
     ----------

2.1  Revenue Flight
     --------------

     A "Revenue Flight" is a flight as stipulated in the Buyer's time table, and
     any scheduled charter flight of the Aircraft.

2.2  Aircraft Inherent Malfunction
     -----------------------------

     An "Aircraft Inherent Malfunction" is a condition whereby maintenance
     action is necessary to reestablish serviceability of the Aircraft.

2.3  Dispatched
     ----------

     An Aircraft will be deemed to have been "Dispatched" when it leaves the
     gate for a Revenue Flight.



<PAGE>




2.4  Chargeable Delay
     ----------------

     A "Chargeable Delay" will be deemed to have occurred when, by more than
     fifteen (15) minutes and for reasons other than those defined under
     "Excluded Delay," a primary Aircraft Inherent Malfunction causes a Revenue
     Flight to depart later than the scheduled departure time.

2.5  Excluded Delay
     --------------

     Any delay which is not a Chargeable Delay is an "Excluded Delay." Excluded
     Delays are specifically excluded from this Guarantee, even if consequently
     the Aircraft is subject to a delay. These Excluded Delays include delays in
     scheduled departure due to:

     -    SERVICING - NO CORRECTIVE MAINTENANCE PERFORMED Struts Oil Hydraulic
          fluid Lubrication All servicing activities that do not require the
          mechanic to
          physically adjust or replace or defer structural repair and replace
          hardware/software Fueling related Deicing Water and waste Sanitizing /
          flushing Moisture condensation Printer paper replacement Routine
          cleaning Tire pressure servicing

     -    PRECAUTIONARY MAINTENANCE - NO CORRECTIVE MAINTENANCE PERFORMED
          Hydraulic leaks - within limits
          Fuel leak - within limits
          Manual closing or cycling passenger/crew/cargo door
          Decals/paint/appearance items
          Passenger amenity lamps
          Tires - worn past limits
          Brakes - worn past limits
          Resetting circuit breakers - no corrective maintenance performed
          according to FAA-approved FCOM



<PAGE>




     -    SCHEDULED MAINTENANCE ACTIVITIES
          COMPLETION OF SCHEDULED/PLANNED WORK CONTENT OF SCHEDULED:
          Maintenance checks
          Maintenance set-ups

     -    PARTS DELAYS AND CANCELLATIONS

     -    EXTERNAL FORCE DAMAGE: AIRCRAFT DAMAGE/LIGHTNING STRIKES, ETC.

     -    KNOWN PERSONNEL ERROR

     -    SECONDARY DELAY/CANCELLATION:
          A previous delay(s) or cancellation(s) of subsequent scheduled flights
          on the same day caused by the same problem that caused the primary
          delay(s) or cancellation(s).

     -    Delays caused by systems or components being designated as "Go if" in
          the Minimum-Equipment List (MEL) as approved by the Buyer's
          airworthiness authorities for the Buyer's operation of the Aircraft.

     -    Delays attributable to the Propulsion Systems.

2.6  Cancellation
     ------------

     A "Cancellation" occurs when a Revenue Flight does not take place. The
     cancellation of any or all of the flight legs of a multi-leg flight
     constitutes only one (1) Cancellation. One (1) Cancellation is counted as
     one (1) event.

2.7  Achieved Dispatch Reliability
     -----------------------------

     "Achieved Dispatch Reliability" is the actual Dispatch Reliability obtained
     by the Aircraft fleet in regular revenue service and adjusted to the
     clauses of this Guarantee. ETOPS flights are not included in this
     Guarantee.

     Achieved Dispatch Reliability, expressed as a percent, will be computed
     every three months ("the Computation Period") and will be compared to the
     Guaranteed Dispatch Reliability level (as defined in Paragraph 3) at the
     end of each Computation Period.

3.   GUARANTEE
     ---------

     The Seller guarantees the "Guaranteed Dispatch Reliability," set forth
     below in Subparagraph 3.1 and 3.2.

3.1  First *** Years of  Guarantee
     -----------------------------

     The Seller guarantees that, from the first three-month Computation Period
     following delivery of the first Aircraft and for Aircraft in commercial
     service, an Aircraft available for dispatch will, on average, have a ***
     percent probability of being dispatched without a Chargeable Delay. This
     probability will be maintained until the end of the *** year of operation
     of the Aircraft fleet following delivery of the first Aircraft.

3.2  Remaining Years of Guarantee
     ----------------------------

     The Seller guarantees that, from the first three-month Computation Period
     after the beginning of the *** year of operation of the Aircraft fleet in
     commercial service until the end of the Term, on average, an Aircraft
     available for dispatch will have a *** percent probability of being
     Dispatched without a Chargeable Delay.

4.   BUYER'S AND SELLER'S OBLIGATION
     -------------------------------

4.1  Buyer's and Seller's Obligations
     --------------------------------

     The Buyer's and Seller's specialists will mutually agree on the details of
     a Chargeable Delay reporting procedure not later than three (3) months
     before delivery of the first Aircraft.

4.2  Buyer's Obligations
     -------------------

     a)  The Buyer will regularly submit Chargeable Delay data on a monthly
         basis not later than twenty (20) days after the end of the reporting
         month. Such data must contain detailed information on delays and
         Cancellations to allow the Seller to



<PAGE>




         assess the nature of system or component malfunctions.

     b)  The Buyer will notify the Seller at any time that the Achieved Dispatch
         Reliability is below the Guaranteed Dispatch Reliability Level. After
         such notice, the Seller will promptly take corrective actions. Upon
         request, all reasonably necessary additional detailed operational and
         engineering information will be provided by the Buyer in order to allow
         the Seller to determine the necessary action.

     c)  The Buyer will incorporate in and apply to the Aircraft the procedures
         and modifications recommended by the Seller to the extent necessary in
         order to improve the Achieved Dispatch Reliability. Said modifications
         will be incorporated and such procedures will be applied as soon as is
         reasonably possible, consistent with the Buyer's maintenance program,
         following receipt of instructions and parts (if applicable) by the
         Buyer, provided that:

         i)   the effect of such a procedure or modification is substantiated to
              the Buyer's satisfaction,

         ii)  application of such a procedure or modification is economical and
              practical as determined by the Buyer's customary analysis
              practice, and

         iii) ***

         In the event of a disagreement between the Seller and the Buyer as to
         the effectiveness of procedures or modifications proposed by the Seller
         to increase the achieved level, the Buyer will demonstrate to the
         Seller that pursuant to its analysis, such a modification or procedure
         is not effective.

         Notwithstanding the Buyer's obligations above, the Buyer may, at its
         option, decline to install such modification or decline to follow such
         revised procedures as are referred to above. If the Buyer so declines,
         the Seller may adjust the Guaranteed Dispatch Reliability Level
         downwards by an amount consistent with the improvement in the Achieved
         Dispatch Reliability Level, based on reasonable substantiation to the
         Buyer and on other operators' experience, if any, that of the
         reliability benefits of such modification or such revised procedures
         are expected to cause.

     d)  Furthermore, the Buyer agrees to set its Aircraft fleet technical
         dispatch reliability goals as shown in the Buyer's regular reliability
         report (or equivalent) at a level equal to or greater than the
         Guaranteed Dispatch Reliability Level, so that both the Buyer's and
         Seller's technical staff can aggressively pursue attainment of the
         Guaranteed Dispatch Reliability Level.

4.3  Seller's Obligations
     --------------------

     During the Term, the Seller will provide technical and operational analyses
     of delays and cancellations and will develop corrections intended to reduce
     delays and, in the event that the Achieved Dispatch Reliability is below
     the Guaranteed Dispatch Reliability Level the Seller will, not later than
     six (6) months where practicable after notification by the Buyer and at no
     charge to the Buyer:

     a)  provide modified Manufacturer's items, either hardware of software, to
         improve Achieved Dispatch Reliability,

     b)  make recommendations concerning the Aircraft operation and maintenance
         programs, publications, and policies to improve Achieved Dispatch
         Reliability,

     c)  assist the Buyer to cause Vendors action to improve the Achieved
         Dispatch Reliability.

5.   ADJUSTMENT
     ----------

     Any design, certification, regulatory, organizational structure or Aircraft
     operation changes outside the Seller's control that may have an effect upon
     the operation and dispatch characteristics of the Aircraft will be cause
     for reevaluation or adjustment of this Guaranteed Dispatch Reliability
     Level by mutual agreement between the Buyer and the Seller.

6.   ACHIEVED DISPATCH RELIABILITY REVIEW MEETINGS
     ---------------------------------------------

     An Achieved Dispatch Reliability review meeting between the Seller's and
     the Buyer's representatives will be scheduled at the end of each six (6)
     month period of Aircraft operation, or at some other period to be mutually
     agreed. Representatives of the Buyer and the Seller will participate in the
     meeting and will:

     a)  review current Achieved Dispatch Reliability,

     b)  eliminate unsupported or non-Aircraft-inherent delay claims from delay
         records to compute Achieved Dispatch Reliability,

     c)  consider corrective action, if required,



<PAGE>




     d)  review the Buyer's incorporation of modifications as stated in
         Subparagraph 4.2 of this Letter Agreement and requirements, if any, for
         reduction of the Guaranteed Dispatch Reliability Level,

     e)  review possible design, certification, regulatory, organizational
         structure or Aircraft operation changes and requirements, if any,
         necessitating adjustment of the Guaranteed Dispatch Reliability Level.

7.   LIABILITY LIMITATION
     --------------------

     The Seller's liability for failure to meet the Dispatch Reliability
     Guarantee values will be governed solely by the terms of this Dispatch
     Reliability Guarantee.

8.   ASSIGNMENT
     ----------

     This Letter Agreement and the rights and obligations of the Buyer hereunder
     will not be assigned or transferred in any manner without the prior written
     consent of the Seller, and any attempted assignment or transfer in
     contravention of the provisions of this Paragraph 8 will be void and of no
     force or effect. Notwithstanding the preceding sentence, the terms of
     Subclauses 19.5 and 19.6 of the Agreement will apply to this Letter
     Agreement.

Airbus Industrie G.I.E., established under "Ordonnance" No. 67-821 dated

guarantees the due and punctual payment and performance by the Seller of all of
the latter's liabilities and obligations as set forth in the said Agreement

agrees that its obligations hereunder will be unconditional and absolute and,
without limiting the generality of the foregoing, will not be released,

obligations thereunder made in accordance with Paragraph 8 thereof. The
Guarantor further agrees that it will execute and deliver such other and further

EXHIBIT 10.2

                        September 5, 1997



John W. Harper
Senior Vice President-Finance and 
   Chief Financial Officer
US Airways, Inc.
2345 Crystal Drive
Arlington, Virginia  22227

Dear John:

     This letter, when countersigned by you, will reflect 
the terms of the agreement between US Airways, Inc. ("US 
Airways" or the "Company") and you concerning the severance 
of your employment.  US Airways has not yet identified your 
successor, and, therefore, we have requested and you have 
agreed to continue in your position while we identify a 
successor and to provide assistance and advice to ensure a 
smooth transition of your responsibilities to your 
successor.  In consideration for your services during this 
period, for your past service to the Company and the mutual 
promises herein contained, US Airways agrees to the 
following:

     1.     You will continue in your current position 
as Senior Vice President-Finance and Chief Financial 
Officer of US Airways, Inc. and US Airways Group, Inc. 
until such time as your successor is elected and a 
reasonable transition period has passed.  US Airways 
will determine in its sole discretion when the 
transition period has been completed.  Notwithstanding 
the foregoing, in the event that no successor is named, 
or under any circumstances, the last day of your active 
employment will be January 15, 1998.  Upon the first to 
occur of the completion of the transition period or 
January 15, 1998, you will resign your positions with 
US Airways, Inc., US Airways Group, Inc., and any other 
positions, including board memberships, at any 
subsidiary corporations.

     2.     Subject to paragraph 5 below addressing 
incentive compensation, during the period from today's 
date through January 15, 1998, you will continue to 
receive your current base salary and all other 
compensation and benefits applicable to your current 
position as a senior officer, to the extent such 
benefits are continued for all other senior officers.  
In the event that a successor is named and a transition 
period is completed prior to January 15, 1998, you will 
continue to receive your base salary and all other 
compensation and benefits as if you remained an active 
employee through January 15, 1998, irrespective of the 
resignation of your employment.

     3.     Within 15 days of your severance, US 
Airways will pay to you in one lump sum, a severance 
payment based upon one year's base salary (i.e., 
$295,000) representative of the period of time from the 
completion of the transition period through the 
anniversary of such date; provided, however, that in 
the event that the transition period is completed prior 
to January 15, 1998, this severance payment will be 
decreased for the period of salary continuation from 
the end of the transition period through January 15, 
1998.

     4.     US Airways agrees to provide you with 
continued service credit under the terms of the non-
qualified supplemental executive retirement agreement 
dated August 8, 1995 between you and the Company 
(hereinafter the "SERP Agreement") through the earlier 
to occur of one year from the completion of the 
transition period or January 15, 1999.  The parties 
acknowledge that the additional service credit will be 
credited under the formula in the SERP Agreement which 
provides for two years of "deemed" credited service for 
each year of actual service.  Additionally, in the 
event that you elect immediate commencement of pension 
benefits upon your severance, the additional service 
credit will be included in the calculation regardless 
of the benefit commencement.

     5.     You agree that you will not be entitled to 
any incentive award under the US Airways Group, Inc. 
Incentive Compensation Plan for the 1997 or the 1998 
fiscal year.

6.  As a result of the separation of your 
employment with US Airways, (a) the remaining 
7,000 shares of restricted stock granted to you 
on November 28, 1995, with a three-year vesting 
schedule, will not vest under the Restricted 
Stock Agreement as currently drafted, and (b) 
the option to purchase 35,000 shares of stock 
at an option price of $25.375, with a five-year 
vesting schedule, will not vest under the terms 
of the Stock Option Agreement as currently 
drafted, if your severance date is before 
November 28, 1997 or March 25, 1998, 
respectively.  US Airways agrees that the 3,000 
shares of restricted stock currently scheduled 
to vest on November 28, 1997 will vest on that 
date irrespective of the status of your 
employment.  The remaining 4,000 shares of 
restricted stock scheduled to vest on November 
28, 1998 will be forfeited on your severance 
date.  Additionally, the option to purchase 
7,000 shares which is currently scheduled to 
vest on March 25, 1998 will vest on that date 
irrespective of the status of your employment 
on that date.  You will have until September 
25, 1998 to exercise those vested options.  The 
option to purchase the remaining 28,000 shares 
of stock will be forfeited on your severance 
date.  The applicable restricted stock and 
stock option agreements will be amended 
accordingly.

     7.     In the event that you elect to commence 
your retirement benefits immediately upon your 
severance, i.e., effective February 1, 1998, you will 
be eligible for all retiree benefits provided to 
employees and senior officers of the Company, as they 
may be amended from time to time, including, but not 
limited to health plan coverage, on-line space positive 
travel privileges, US Airways Club privileges and 
split-dollar life insurance continuation.

     8.     The parties agree that the severance of 
your employment is by mutual agreement pursuant to 
paragraph 5(a) of the Employment Agreement between you 
and the Company dated January 27, 1993 and you 
expressly waive your right to any of the rights, 
compensation, benefits or other Company obligations 
under said Employment Agreement effective with your 
signing of this letter.  You agree that this document 
contains the entire understanding of the parties 
related to the severance of your employment and the 
rights and obligations of the parties upon the 
severance of your employment.

     9.     You agree to hold in a fiduciary capacity 
for the benefit of US Airways and will not disclose 
without the prior written consent of US Airways, all 
confidential and proprietary information, knowledge or 
data relating to US Airways, its parent, subsidiary or 
affiliated companies, which was obtained by you during 
your employment with US Airways unless such 
information, knowledge or data is known to the general 
public (other than by acts by you).  You further agree 
not to disclose or make public, orally, in writing, or 
otherwise, any disparaging statements, or any 
information which would cause public discredit, about 
US Airways, its parent, subsidiary or affiliated 
companies, or their respective directors, officers or 
employees.  In the event that you are subpoenaed or 
otherwise compelled by court order to provide 
information which would violate this non-
disclosure/non-disparagement provision, you will notify 
US Airways before responding to any such request for 
testimony or information to afford US Airways an 
opportunity to assert any objection it may have.  In 
the event that US Airways determines that you have 
breached this non-disclosure/non-disparagement 
provision you will forfeit eligibility for all of the 
compensation and benefits provided for in this 
agreement.  Any compensation or benefits paid to you 
prior to such  must be repaid to US Airways within 15 
days of your receipt of written notification of such 
breach from US Airways.  US Airways reserves the right 
to pursue any other legal or equitable remedies 
available to it to enforce this non-disclosure/non-
disparagement provision.
