PART I

ITEM 1. BUSINESS

DESCRIPTION OF BUSINESS

Southwest Airlines Co. (Southwest) is a major domestic airline that provides shorthaul, high frequency, point-to-point, low fare service. Southwest was incorporated in Texas and commenced Customer Service on June 18, 1971 with three Boeing 737 aircraft serving three Texas cities - Dallas, Houston, and San Antonio.

At yearend 1996, Southwest operated 243 Boeing 737 aircraft and provided service to 50 airports in 49 cities in 24 states throughout the United States. Southwest commenced service to Jacksonville, Florida in January 1997, and has recently announced that it will commence service to Jackson, Mississippi in August 1997.

On December 31, 1993, Southwest acquired Morris Air Corporation (Morris) in a stock-for-stock exchange, issuing approximately 3.6 million shares of Southwest Common Stock in exchange for all of the outstanding shares of Morris. During 1994, the operations of Morris were substantially integrated with those of Southwest, and Morris ceased service as a certificated air carrier in March 1995. Unless the context requires otherwise, references in this annual report to the "Company" include Southwest and Morris.

The business of the Company is somewhat seasonal. Quarterly operating income and, to a lesser extent, revenues tend to be lower in the first quarter (January 1 - March 31).

FUEL

The cost of fuel is an item having significant impact on the Company's operating results. The Company's average cost of jet fuel per gallon for scheduled carrier service over the past five years was as follows:

1992                      $.61
1993                      $.59
1994                      $.54
1995                      $.55
1996                      $.65

The Company is unable to predict the extent of future fuel cost changes. The Company has standard industry arrangements with major fuel suppliers. Standard industry fuel contracts do not provide material protection against price increases or for assured availability of supplies. The Company's principal hedging program utilizes the purchase of crude oil call options at a nominal premium and at volumes of up to 30% of its annual fuel requirements. Although market conditions can significantly impact the price of jet fuel, at present these conditions have not resulted in an inadequate supply of jet fuel. For more discussion of current jet fuel costs and the impact of these costs on the Company's operations, see Management's Discussion and Analysis of Financial Condition and Results of Operations.

REGULATION

Economic. The Dallas Love Field section of the International Air Transportation Competition Act of 1979 (Competition Act), as it affects Southwest's scheduled service, provides that no common carrier may provide scheduled passenger air transportation for compensation between Love Field and one or more points outside Texas, except that an air carrier may transport individuals by air on a flight between Love Field and one or more points within the states of Arkansas, Louisiana, New Mexico, Oklahoma, and Texas if (a) "such air carrier does not offer or provide any through service or ticketing with another air carrier" and (b) "such air

1

carrier does not offer for sale transportation to or from, and the flight or aircraft does not serve, any point which is outside any such states." Southwest does not interline or offer joint fares with any other air carrier at Love Field. The Competition Act does not restrict Southwest's intrastate Texas flights or its air service from points other than Love Field to points beyond Texas and the four contiguous states.

The Department of Transportation (DOT) has significant regulatory jurisdiction over passenger airlines. Unless exempted, no air carrier may furnish air transportation over any route without a DOT certificate of authorization, which does not confer either exclusive or proprietary rights. The Company's certificates are unlimited in duration and permit the Company to operate among any points within the United States, its territories and possessions, except as limited by the Love Field section of the Competition Act, as do the certificates of all other U.S. carriers. DOT may revoke such certificates, in whole or in part, for intentional failure to comply with any provisions of subchapter IV of the Federal Aviation Act of 1958, or any order, rule or regulation issued thereunder or any term, condition or limitation of such certificate; provided that, with respect to revocation, the certificate holder has first been advised of the alleged violation and has been given a reasonable time to effect compliance.

DOT prescribes uniform disclosure standards regarding terms and conditions of carriage, and prescribes that terms incorporated into the Contract of Carriage by reference are not binding upon passengers unless notice is given in accordance with its regulations.

Several bills have been introduced in Congress with a goal of "reforming" the Federal Aviation Administration ("FAA") by, among other things, modifying the method of funding the FAA. For information regarding the impact of the lapse and reinstatement of the 10% federal excise tax on operating results, see Management's Discussion and Analysis of Financial Condition and Results of Operations. At the current time, Southwest is unable to predict how these issues will be resolved and what impact, if any, resolution of these uncertainties will have on future operating results or financial condition.

Safety. The Company is subject to the jurisdiction of the FAA with respect to its aircraft maintenance and operations, including equipment, ground facilities, dispatch, communications, flight training personnel, and other matters affecting air safety. To ensure compliance with its regulations, the FAA requires airlines to obtain operating, airworthiness and other certificates which are subject to suspension or revocation for cause. The Company has obtained such certificates. The FAA, acting through its own powers or through the appropriate U. S. Attorney, also has the power to bring proceedings for the imposition and collection of fines for violation of the Federal Air Regulations.

Environmental. The Airport Noise and Capacity Act of 1990 (ANCA) requires the phase out of Stage 2 airplanes (which meet less stringent noise emission standards than later model Stage 3 airplanes) in the contiguous 48 states by December 31, 1999. FAA rules establish a future interim compliance date for ANCA of December 31, 1998. An operator may comply by either implementing a reduction of the operator's base level, as defined in ANCA, of Stage 2 aircraft by at least 75 percent at December 31, 1998, or by operating a fleet that is at least 75 percent Stage 3 by December 31, 1998. Operation of Stage 2 aircraft after December 31, 1999 is prohibited, subject, however, to an extension of the final compliance date to December 31, 2003, if at least 85 percent of the aircraft used by the operator in the contiguous United States will comply with Stage 3 noise levels by July 1, 1999 and the operator successfully obtains a waiver from the FAA of the December 31, 1999 final phaseout date. Statutory requirements to obtain a waiver include a determination by the FAA that the waiver is in the public interest or would enhance competition or benefit service to small communities. There is no assurance that such a waiver is obtainable.

The Company's fleet, as of December 31, 1996, consisted of 47 Stage 2 aircraft and 196 Stage 3 aircraft, yielding a Stage 3 percentage of over 80 percent. Accordingly, the Company exceeds the Stage 3 fleet percentage requirement for the December 31, 1998 interim compliance date.

2

As of December 31, 1996, of the 47 Stage 2 aircraft operated by the Company, 26 are leased from third parties and 21 are owned by the Company. Because the Company already complies with the December 31, 1998 interim compliance requirement of a 75 percent Stage 3 fleet, the Company could operate all 47 of its Stage 2 aircraft until December 31, 1999. Based upon the Company's current schedule for delivery of new Stage 3 aircraft, including options, and the Company's planned retirement schedule for Stage 2 aircraft, assuming no hushkitting, the Company will achieve 85 percent compliance by July 1, 1999; however, the Company currently intends to hushkit at least 20 aircraft. This would qualify the Company to apply for a waiver from the final compliance date, which, if obtained, could permit the Company to continue operation of the then remaining Stage 2 aircraft until, at the latest, December 31, 2003.

ANCA also requires the FAA to establish parameters within which any new Stage 2 and Stage 3 noise or access restrictions at individual airports must be developed. The published rules generally provide that local noise restrictions on Stage 3 aircraft first effective after October 1990 require FAA approval, and establish a regulatory notice and review process for local restrictions on Stage 2 aircraft first proposed after October 1990. Certain airports, including Dallas Love Field, Los Angeles, San Diego, San Francisco, and Orange County, have established airport restrictions to limit noise, including restrictions on aircraft types to be used and limits on the number of hourly or daily operations or the time of such operations. In some instances, these restrictions have caused curtailments in service or increases in operating costs and such restrictions could limit the ability of Southwest to expand its operations at the affected airports. Local authorities at other airports are considering adopting similar noise regulations.

Operations at John Wayne Airport, Orange County, California, are governed by the Airport's Phase 2 Commercial Airline Access Plan and Regulation (the "Plan"). Pursuant to the Plan, each airline is allocated total annual seat capacity to be operated at the airport, subject to renewal/reallocation on an annual basis. Service at this airport may be adjusted annually to meet these requirements.

The Company is subject to various other federal, state, and local laws and regulations relating to the protection of the environment, including the discharge of materials into the environment.

MARKETING AND COMPETITION

Southwest focuses principally on point-to-point, rather than hub-and-spoke, service in shorthaul markets with frequent, conveniently timed flights, and low fares. For example, Southwest's average aircraft trip length in 1996 was 410 miles with an average duration of approximately one hour. At yearend, Southwest served approximately 400 one-way nonstop city pairs with an average weekday frequency of just over 5 roundtrips per city pair.

Southwest's point-to-point route system, as compared to hub-and-spoke, provides for more direct nonstop routings for shorthaul customers and, therefore, minimizes connections, delays, and total trip time. Southwest focuses on nonstop, not connecting, traffic. As a result, approximately 80 percent of the Company's customers fly nonstop. In addition, Southwest serves many conveniently-located satellite or downtown airports such as Dallas Love Field, Houston Hobby, Chicago Midway, Baltimore, Burbank, Oakland, San Jose, Providence and Ft. Lauderdale airports, which are typically less congested than other airlines' hub airports and enhance the Company's ability to sustain high employee productivity and reliable ontime performance. This operating strategy also permits the Company to achieve high asset utilization. Aircraft are scheduled to minimize the amount of time the aircraft is at the gate, approximately 20 minutes, thereby reducing the number of aircraft and gate facilities that would otherwise be required.

Southwest does not interline with other domestic jet airlines, nor have any commuter feeder relationships. However, in late 1996 the Company entered into a marketing relationship with Icelandair, pursuant to which Icelandair may offer travel to Customers going between Cleveland and various foreign Icelandair destinations,

3

via Baltimore. Southwest provides the transportation between Cleveland and Baltimore on its regularly scheduled service.

Southwest employs a very simple fare structure, featuring low, unrestricted, unlimited everyday coach fares. The Company operates only one aircraft type, the Boeing 737, which simplifies scheduling, maintenance, flight operations, and training activities.

In May 1994, the computer reservations systems (CRSs) owned by United Airlines (Apollo) and Continental Airlines (System One) disabled automated ticketing for Southwest travel. Rather than pay the fees associated with CRS participation in Apollo and System One, Southwest took the following actions:
Southwest introduced a Ticketless travel option, available system-wide in January 31, 1995, eliminating the need to print a paper ticket altogether; provided direct access to its own reservation system and ticketing for the 50 largest travel agencies (SWAT); instituted overnight delivery of Southwest-produced tickets for approximately 300 large travel agencies; and improved access to Ticket By Mail for direct Customers by reducing the time limit from seven days out from the date of travel to three days. Southwest also entered into a new arrangement with SABRE, the CRS in which Southwest has historically participated to a limited extent, providing for ticketing and automated booking on Southwest in a very cost-effective manner. In 1996, Southwest began offering ticketless travel through the Company's home page on the Internet's World Wide Web at http://www.iflyswa.com. By December 31, 1996, approximately 50% of Southwest's customers were choosing the ticketless travel option.

The airline industry is highly competitive as to fares, frequent flyer benefits, routes, and service, and some carriers competing with the Company have greater financial resources, larger fleets, and wider name recognition. Several of the Company's larger competitors have initiated or are studying low-cost, shorthaul service in markets served by the Company, which represents a more direct threat in Southwest's market niche. Profit levels in the air transport industry are highly sensitive to changes in operating and capital costs and the extent to which competitors match an airline's fares and services. The profitability of a carrier in the airline industry is also impacted by general economic trends. For more discussion on the current competitive environment for Southwest, see Management's Discussion and Analysis of Financial Condition and Results of Operations.

The Company is also subject to varying degrees of competition from surface transportation in its shorthaul markets, particularly the private automobile. In shorthaul air services which compete with surface transportation, price is a competitive factor, but frequency and convenience of scheduling, facilities, transportation safety, and Customer Service may be of equal or greater importance to many passengers.

INSURANCE

The Company carries insurance of types customary in the airline industry and in amounts deemed adequate to protect the Company and its property and to comply both with federal regulations and certain of the Company's credit and lease agreements. The policies principally provide coverage for public and passenger liability, property damage, cargo and baggage liability, loss or damage to aircraft, engines, and spare parts, and workers' compensation.

FREQUENT FLYER AWARDS

Southwest's frequent flyer program, Rapid Rewards (formerly The Company Club), is based on trips flown rather than mileage. Rapid Rewards offers one free roundtrip travel award to any Southwest destination after flying eight roundtrips (or 16 one-way trips) on Southwest within a consecutive twelve-month period.

The trips flown as credit towards a free travel award certificate are valid for twelve months only; the free travel award is automatically generated when earned by the Customer rather than allowing the Customer to

4

bank the trip credits indefinitely; and the free travel award is valid for one year with an automatic expiration date. Based on the issuance of free travel awards to qualified members, coupled with the foregoing program characteristics and the use of "black out" dates for the free travel awards during peak holiday periods, the financial impact of free travel awards used on the Company's consolidated financial statements has not been material. Free travel awards redeemed were approximately 459,000, 417,000, and 279,000 during 1996, 1995, and 1994, respectively. The amount of free travel award usage as a percentage of total Southwest revenue passengers carried was 1.9 percent in 1996, 1.9 percent in 1995, and 1.4 percent in 1994.

The Company accounts for free travel awards using the incremental cost method, consistent with the other major airlines. This method recognizes an average incremental cost to provide roundtrip transportation to one additional passenger. The incremental cost to provide free transportation is accrued at the time an award is earned and revenue is subsequently recognized, at the amount accrued, when the free travel award is used. The estimated incremental costs include passenger costs such as beverage and snack supplies, baggage claims, baggage handling, and liability insurance; operations costs such as security services, airport rentals, fuel, oil, and into-plane charges; and reservations costs, such as communications and system operations fees. The liability for free travel awards earned but not used at December 31, 1996 and 1995 was not material.

The number of free travel awards for Southwest outstanding at December 31, 1996 and 1995 was approximately 404,000 and 295,000, respectively. These numbers do not include partially earned awards. The Company currently does not have a system to accurately estimate partially earned awards. However, these partially earned awards may equate to approximately 60-70 percent of the current outstanding awards. Since the inception of Rapid Rewards in 1987, approximately 15 percent of all award certificates have expired without being used.

EMPLOYEES

At December 31, 1996, Southwest had 22,944 active employees, consisting of 6,228 flight, 1,049 maintenance, 13,148 ground customer service and 2,519 management, accounting, marketing, and clerical personnel.

Southwest has ten collective bargaining agreements covering approximately 84 percent of its employees. Southwest's Customer service and reservation employees are subject to an agreement with the International Association of Machinists and Aerospace Workers, AFL-CIO (IAM), which becomes amendable in November 1997. Flight attendants are subject to an agreement with the Transportation Workers Union of America, AFL-CIO (TWU), which became amendable May 31, 1996 and is currently in negotiations. Fleet service employees are subject to an agreement with the TWU which becomes amendable in December 1999. The pilots are subject to an agreement with the Southwest Airlines Pilots' Association (SWAPA), which becomes amendable in September 1999 (described below). Flight dispatchers are represented by the Southwest Airlines Employees Association, pursuant to an agreement which becomes amendable in November 1997. Aircraft cleaners and stock clerks; mechanics, flight simulator technicians and flight crew training instructors are represented by the International Brotherhood of Teamsters pursuant to separate agreements which become amendable in August 2000, August 2001, October 2000 and December 2000, respectively. The flight/ground school instructors are subject to an agreement with the Southwest Airlines Professional Instructors Association which becomes amendable in December 2000.

In January 1995, Southwest's pilots ratified a ten-year labor contract that calls for no wage increases in the first five years and three percent annual wage increases in three of the last five years of the contract. Initially, the pilots received options to purchase approximately 14.5 million shares of Southwest common stock at $20 per share over the term of the contract; pilots hired subsequently receive additional grants at a five percent premium over then current fair market value, up to a total of 18,000,000 shares that can be issued under the stock option plan. Pilots are eligible for profitability bonuses of up to three percent of compensation in three of the first five years and profitability-based pay increases up to three percent in two of the second

5

five years of the contract. The pilot group may choose to reopen the contract after five years, in which event all unexercised options will terminate on December 1, 1999.

ITEM 2. PROPERTIES

AIRCRAFT

Southwest operated a total of 243 Boeing 737 aircraft as of December 31, 1996, of which 106 and 13 were under operating and capital leases, respectively. The remaining 124 aircraft were owned.

In January 1994, Southwest entered into an agreement with The Boeing Company, pursuant to which Southwest is the launch customer for the Boeing 737-700 aircraft, the newest generation of the Boeing 737 aircraft type. As the launch customer, Southwest has agreed to purchase sixty-three Boeing 737-700 aircraft from 1997 to 2001, with options for an additional sixty-seven 737-700 aircraft from 1998 to 2004. The first four 737-700 aircraft will be delivered to the Company in late 1997.

In total, at December 31, 1996, the Company had 78 firm orders and 67 options as follows:

 Type       Seats   1996    1997    1998    1999    2000    2001    2002    2003   2004

The average age of the Company's fleet at December 31, 1996 was 7.9 years.

For information regarding the Company's obligations under capital leases and noncancelable operating leases see Notes 4 and 5 to the Consolidated Financial Statements.

For information concerning Southwest's aircraft purchase commitments, see Note 2 to the Consolidated Financial Statements.

The Company has an agreement with CFM International, Inc. (a joint company of SNECMA (France) and General Electric Company) dated May 28, 1981, as amended, for the supply of spare engines for its Boeing 737-300, -500, and -700 aircraft. CFM also supplies the engines to The Boeing Company for original installation on such aircraft. CFM is the sole manufacturer of engines for use on the Boeing 737-300, -400, -500, and -700 aircraft.

GROUND FACILITIES AND SERVICES

Southwest leases terminal passenger service facilities at each of the airports it serves to which it has added various leasehold improvements. The Company leases land on a long-term basis for its maintenance centers located at Dallas Love Field, Houston Hobby, and Phoenix Sky Harbor, its training center near Love Field which houses three 737 simulators, and its corporate headquarters also located near Love Field. The maintenance, training center, and corporate headquarters buildings on these sites were built and are owned by Southwest. At December 31, 1996, the Company operated nine reservation centers. The reservation centers located in Little Rock, Arkansas; Chicago, Illinois; Albuquerque, New Mexico; and Oklahoma City, Oklahoma occupy leased space. The Company owns its Dallas, Texas; Houston, Texas; Phoenix, Arizona; Salt Lake City, Utah; and San Antonio, Texas reservation centers.

The Company performs substantially all line maintenance on its aircraft and provides ground support services at most of the airports it serves. However, the Company has arrangements with certain aircraft

6

maintenance firms for major component overhauls and repairs for its airframes and engines, which comprise the majority of the annual maintenance costs.

In recent years, many airports have increased or sought to increase the rates charged to airlines. The extent to which such charges are limited by statute and the ability of airlines to contest such charges has been subject to litigation and to administrative proceedings before the Department of Transportation. To the extent the limitations on such charges are relaxed or the ability of airlines to challenge such charges is restricted, the rates charged by airports to airlines may increase substantially. Management cannot predict the magnitude of any such increase.

ITEM 3. LEGAL PROCEEDINGS

Southwest has received examination reports from the Internal Revenue Service proposing certain adjustments to Southwest's income tax returns for 1987 through 1991. The adjustments relate to certain types of aircraft financings consummated by Southwest, as well as other members of the aviation industry, during that time period. Southwest intends to vigorously protest the adjustments made with which it does not agree. The industry's differences with the IRS involve complex issues of law and fact which are likely to take a substantial period of time to resolve. Management believes that final resolution of such protest will not have a materially adverse effect upon the results of operations of Southwest.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None to be reported.

RECENT SALES OF UNREGISTERED SECURITIES

The Company re-employed Herbert D. Kelleher, effective as of January 1, 1996, as President and Chief Executive Officer under a five-year Employment Contract. Pursuant to this Contract, Mr. Kelleher was granted nonstatutory options to purchase, subject to his employment for four years, 144,395 shares of the Company's Common Stock at a purchase price of $1 per share and 500,000 shares at a purchase price of $23.50 per share, representing the composite tape closing sales price of the Common Stock on the New York Stock Exchange on January 2, 1996. One-fifth of the options are not subject to vesting and may be exercised at any time as to the underlying shares. Provided Mr. Kelleher remains in the continuous, full-time employ of the Company, the balance of the options will become exercisable in cumulative increments of one-fifth of the underlying shares each January 1 beginning January 1, 1997; provided that in the event of a change of control of the Company all of the options become immediately exercisable. Each of the options will expire ten years after it becomes exercisable. The options are not transferable by Mr. Kelleher other than by will or the laws of descent and distribution, and are exercisable during Mr. Kelleher's lifetime only by him. The options granted to Mr. Kelleher in 1996 are in addition to options granted to him pursuant to earlier employment agreements.

During 1996, Mr. Kelleher exercised unregistered options to purchase Southwest Common Stock as follows:

The issuance of the above options and shares to Mr. Kelleher were deemed exempt from the registration provisions of the Securities Act of 1933, as amended (the "Act"), by reason of the provision of Section 4(2) of the Act because, among other things, of the limited number of participants in such transactions and the agreement and representation of Mr. Kelleher that he was acquiring such securities for investment and not with a view to distribution thereof. The certificates representing the shares issued to Mr. Kelleher contain a legend to the effect that such shares are not registered under the Act and may not be transferred except pursuant to a registration statement which has become effective under the Act or to an exemption from such registration. The issuance of such shares was not underwritten.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

YEAR IN REVIEW

Southwest and the airline industry continued to post record profits in 1996. Southwest's net income for the first half of 1996 benefitted from the lapse in the ten percent federal ticket tax on December 31, 1995. Net income for the second half of 1996 fell below year ago levels primarily due to significant increases in jet fuel prices.

Southwest continued to maintain our advantage as the low cost leader in the industry. Despite this advantage, we continue pursuing numerous cost reduction efforts, which have proven to be beneficial.

We added 22 new Boeing 737-300 aircraft to our fleet in 1996 and retired three
- - -200s. Our fleet remains one of the youngest fleets in the industry with an average age of 7.9 years. In October 1997, we will be the launch customer for the new Boeing 737-700 aircraft. In total for 1997, we will accept delivery of 15 -300s and four -700s. We currently plan to retire four -200s in fourth quarter 1997.

Our expansion into Florida in 1996 has been successful with strong load factors. We added Jacksonville, Florida service beginning January 15, 1997. Service to Providence, Rhode Island, which began October 27, 1996, also looks promising. Our current plans for capacity growth in 1997 will be primarily directed to cities we presently serve, either with increased frequencies or new routes. We may begin service to one more new city later in 1997.

Proposed FAA "funding reform" continues to present uncertainty as to how or if any changes would impact Southwest. While Congress reinstated the ten percent ticket tax in August 1996, the tax lapsed again as of December 31, 1996. At the current time, Southwest is unable to predict how this FAA funding issue will be resolved and what impact, if any, resolution of this uncertainty will have on future operating results.

RESULTS OF OPERATIONS

1996 COMPARED WITH 1995 The Company's consolidated net income for 1996 was $207.3 million ($1.37 per share), as compared to the corresponding 1995 amount of $182.6 million ($1.23 per share), an increase of 13.5 percent.

OPERATING REVENUES Consolidated operating revenues increased by 18.6 percent in 1996 to $3,406.2 million, compared to $2,872.8

12

million for 1995. This increase in 1996 operating revenues was derived primarily from an 18.4 percent increase in passenger revenues. Revenue passenger miles (RPMs) increased 16.1 percent in 1996, compared to a 12.6 percent increase in available seat miles (ASMs), resulting in an increase in load factor from 64.5 percent in 1995 to 66.5 percent in 1996. The 1996 ASM growth resulted from the net addition of 19 aircraft during the year: 22 additions and three retirements.

In December 1995, because of the impasse in the federal budget, Congress allowed the ten percent federal ticket tax to lapse. This benefitted Southwest's revenues until late August when Congress reimposed the tax through December 31, 1996. The reimposition of the ticket tax negatively impacted revenues in third and fourth quarters 1996 as compared to revenue trends in the first half of 1996.

In celebration of the Company's 25th Anniversary, Southwest launched a fare sale in July for travel between August 19 and October 31, 1996. The sale was extremely popular and resulted in record advance bookings, with more than four and a half million seats sold. Although July and early August load factors and revenues were negatively impacted by the telephone line congestion experienced during the sale, revenues for September and October 1996 were positively impacted with very heavy passenger volumes.

Freight revenues in 1996 were $80.0 million, compared to $65.8 million in 1995. The 21.5 percent increase in freight revenues exceeded the 12.6 percent increase in ASMs for the same period primarily due to increased air freight volumes and United States mail services primarily resulting from the development of new markets added in 1995 and early 1996.

Other revenues increased by 23.3 percent in 1996 to $56.9 million, compared to $46.2 million in 1995. This increase is primarily due to increased charter revenue.

OPERATING EXPENSES Consolidated operating expenses for 1996 were $3,055.3 million, compared to $2,559.2 million in 1995, an increase of 19.4 percent, compared to the 12.6 percent increase in capacity. Operating expenses per ASM increased 6.1 percent in 1996 compared to 1995, primarily due to significantly higher jet fuel prices along with the 4.3 cent per gallon federal jet fuel tax implemented October 1, 1995. Excluding jet fuel costs and related taxes, operating expenses per ASM were up 3.1 percent in 1996 compared to 1995.

Unit costs are expected to increase in first quarter 1997 versus first quarter 1996, due to higher jet fuel prices. (The

13

immediately preceding sentence is a forward-looking statement which involves uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, the largely unpredictable levels of fuel prices.)

Operating expenses per ASM for 1996 and 1995 were as follows:

Salaries, wages, and benefits per ASM increased 2.3 percent in 1996. This increase resulted primarily from a 16.2 percent increase in 1996 average headcount, which outpaced the 1996 capacity (ASM) increase of 12.6 percent, and offset a 0.8 percent decrease in average salary and benefits cost per Employee. The 16.2 percent increase in average headcount was primarily the result of a 24.3 percent increase in Reservations Sales Agents in 1996. Excluding Reservations Sales Agents, total average headcount increased 13.1 percent, in line with capacity.

Southwest's mechanics are subject to an agreement with the International Brotherhood of Teamsters, Chauffeurs, Warehousemen and Helpers of America (the Teamsters), which became amendable August 16, 1995. The Company reached an agreement with the Teamsters which was ratified by its membership in March 1996. The Company's flight attendants are subject to an agreement with the Transport Workers Union of America, AFL-CIO (TWU), which became amendable May 31, 1996. Southwest is currently in negotiations with TWU to amend the contract.

14

Fuel and oil expenses per ASM increased 17.8 percent in 1996, primarily due to an 18.6 percent increase in the average jet fuel cost per gallon from 1995. The average price paid for jet fuel in 1996 was $.6547 compared to $.5522 in 1995. During fourth quarter 1996, the average cost per gallon increased 25.0 percent to $.7323 compared to $.5859 in fourth quarter 1995. In January 1997, fuel prices have averaged approximately $.76 per gallon.

Maintenance materials and repairs per ASM increased 3.3 percent in 1996 compared to 1995 primarily as a result of increased scheduled airframe inspections during 1996.

Agency commissions per ASM increased 2.9 percent in 1996 compared to 1995, which was slightly slower than the 5.2 percent increase in passenger revenues per ASM.

Landing fees and other rentals per ASM increased 4.5 percent in 1996 compared to 1995, which included an airport credit of $4.9 million.

Depreciation expense per ASM increased 4.7 percent in 1996 compared to 1995 due to an increase in the percentage of owned aircraft.

Other operating expenses per ASM increased 9.4 percent in 1996 compared to 1995. This increase was primarily due to increased advertising costs resulting from the expansion into Florida and Providence, Rhode Island, as well as a new advertising campaign; the 4.3 cents per gallon tax on commercial aviation jet fuel purchased for use in domestic operations, which became effective October 1, 1995; and increased airport security costs. The additional fuel tax increased 1996 and 1995 "other operating expenses" by $32.7 million and $7.4 million, respectively.

OTHER "Other expenses (income)" included interest expense, capitalized interest, interest income, and nonoperating gains and losses. Capitalized interest decreased $9.1 million in 1996 as a result of certain amendments to aircraft purchase contracts during third quarter 1995 that affected the timing of payments. Interest income for 1996 increased $5.7 million primarily due to higher invested cash balances.

INCOME TAXES The provision for income taxes, as a percentage of income before taxes decreased in 1996 to 39.3 percent from 40.2 percent in 1995. The decrease was primarily the result of lower effective state tax rates.

1995 COMPARED WITH 1994 The Company's consolidated net income for 1995 was $182.6 million ($1.23 per share), as compared to the

15

corresponding 1994 amount of $179.3 million ($1.22 per share), an increase of 1.8 percent.

Operating Revenues Consolidated operating revenues increased by 10.8 percent in 1995 to $2,872.8 million, compared to $2,591.9 million for 1994. This increase in 1995 operating revenues was derived from a 10.5 percent increase in passenger revenues. RPMs increased 7.9 percent in 1995, compared to a 12.6 percent increase in ASMs, resulting in a decrease in load factor from 67.3 percent in 1994 to 64.5 percent in 1995. The 1995 ASM growth resulted from the addition of 25 aircraft during the year.

Freight revenues in 1995 were $65.8 million, compared to $54.4 million in 1994. The 21.0 percent increase in freight revenues exceeded the 12.6 percent increase in ASMs for the same period primarily due to increased air freight volumes and United States mail services primarily resulting from the development of new markets added throughout 1994 and 1995.

Operating Expenses Consolidated operating expenses for 1995 were $2,559.2 million, compared to $2,275.2 million in 1994, an increase of 12.5 percent, compared to the 12.6 percent increase in ASMs. For the second consecutive year, operating expenses on a per-ASM basis decreased year-over-year, down .1 percent in 1995.

Salaries, wages, and benefits per ASM increased 1.9 percent in 1995. This increase resulted primarily from a 17.8 percent increase in 1995 average headcount, which outpaced the 1995 capacity (ASM) increase of 12.6 percent, and offset a 2.6 percent decrease in average salary and benefits cost per Employee. The 17.8 percent increase in average headcount was primarily the result of a 44.6 percent increase in Reservations Sales Agents in 1995. Excluding Reservations Sales Agents, total average headcount increased only 11.4 percent. The Reservations Sales Agent increase coincided with increased demand for reservations capacity following 1994 enhancements to Southwest's ticket delivery systems for direct Customers.

Employee profitsharing and savings plans expense per ASM increased 4.5 percent in 1995. The increase is primarily the result of increased matching contributions to Employee savings plans resulting from increased Employee participation and higher matching rates in 1995 for non-contract Employees and certain Employee groups covered by collective bargaining agreements.

Fuel and oil expenses per ASM increased 1.0 percent in 1995, primarily due to a 2.4 percent increase in the average jet fuel cost per gallon from 1994. Jet fuel prices remained relatively stable throughout most of 1995, with quarterly averages through

16

the first three quarters ranging from $.53 to $.55 per gallon. During fourth quarter 1995, the average cost per gallon increased to $.59 and, in January 1996, averaged approximately $.62 per gallon.

Maintenance materials and repairs per ASM increased 1.7 percent in 1995 compared to 1994 primarily as a result of performing more engine overhauls during 1995.

Agency commissions per ASM decreased 17.1 percent in 1995 compared to 1994, due to a lower mix of travel agency sales in 1995. The lower travel agency sales mix resulted from 1994 enhancements to Southwest's ticket delivery systems for direct Customers, as described below.

In response to actions taken by our competitor-owned reservations systems in 1994, we reduced our operating costs and enhanced our ticket delivery systems by developing our own Southwest Airlines Air Travel ("SWAT") system allowing high-volume travel agents direct access to reservations; introduced overnight ticket delivery for travel agents; reduced to three the number of advance days reservations required for overnight delivery of tickets to consumers (Ticket By Mail); developed our own Ticketless system, which was rolled out system-wide on January 31, 1995; and effective March 30, 1995 subscribed to a new level of service with SABRE that automates the booking process for SABRE travel agencies.

Aircraft rentals per ASM increased 11.9 percent in 1995. The increase primarily resulted from second and third quarter 1995 sale/leaseback transactions involving ten new 737-300 aircraft and a higher percentage of the fleet consisting of leased aircraft.

Other operating expenses per ASM decreased 2.8 percent in 1995 compared to 1994. This decrease was primarily due to operating efficiencies resulting from the transition of Morris operating functions to Southwest commencing first quarter 1994, and lower communications costs. Communications costs decreased approximately 15 percent per ASM primarily due to lower negotiated rates, increased reservations operations efficiencies, and enhancements to the Company's ticket delivery system.

In August 1993, the Revenue Reconciliation Act of 1993 was enacted, which, among other things, included an assessment of a 4.3 cents per gallon tax on commercial aviation jet fuel purchased for use in domestic operations, which became effective September 30, 1995. This additional fuel tax increased 1995 "other operating expenses" by $7.4 million.

17

Other "Other expenses (income)" included interest expense, capitalized interest, interest income, and nonoperating gains and losses. Interest expense increased $5.4 million in 1995 due to the March 1995 issuance of $100 million senior unsecured 8% Notes due 2005. Capitalized interest increased $5.0 million in 1995 as a result of higher levels of progress payments on aircraft compared to 1994. Interest income for 1995 increased $10.9 million primarily due to higher invested cash balances and higher short-term interest rates.

Income Taxes The provision for income taxes as a percentage of income before taxes was relatively unchanged year over year.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided from operations was $615.2 million in 1996, compared to $456.4 million in 1995. During 1996, additional funds of $330.0 million were generated from the sale and leaseback of ten new 737-300 aircraft subject to long-term operating leases (increasing total commitments for operating leases by $588.8 million).

During 1996, capital expenditures of $677.4 million primarily were for the purchase of 22 new 737-300 aircraft, one used 737-200 aircraft previously leased by the Company, and progress payments for future aircraft deliveries. At December 31, 1996, capital commitments of the Company consisted primarily of scheduled aircraft acquisitions.

The Company recently announced its intention to order 20 hushkits for our 737-200 fleet, with an option for 14 more, for delivery in 1997-1999. These hushkits, with an approximate cost of $1.0 million per aircraft, will make the Stage 2 -200 aircraft compliant with Stage 3 noise requirements.

As of January 1997, Southwest had 78 new 737s on firm order, including 19 to be delivered in 1997, with options to purchase another 67. Aggregate funding required for firm commitments approximated $1,960.1 million through the year 2001 of which $515.1 million related to 1997. See Note 2 to the Consolidated Financial Statements for further information.

In September 1996, the Company's Board of Directors reaffirmed a 1990 authorization for the Company to purchase shares of its common stock from time-to-time on the open market. The authorization reaffirmed the purchase of up to 2,500,000 shares. As of February 21, 1997, no shares have been purchased pursuant to this authority since 1990.

The Company has various options available to meet its capital and operating commitments, including cash on hand at December 31, 1996

18

of $581.8 million, internally generated funds, and a revolving credit line with a group of banks of up to $460 million (none of which had been drawn at December 31, 1996). In addition, the Company will also consider various borrowing or leasing options to maximize earnings and supplement cash requirements.

The Company currently has outstanding shelf registrations for the issuance of $114.4 million of public debt securities which it currently intends to utilize for aircraft financings in 1997.

Cash provided from operations was $456.4 million in 1995 as compared to $412.7 million in 1994. During 1995, additional funds of $321.7 million were generated from the sale and leaseback of ten new 737-300 aircraft subject to long-term operating leases (increasing total commitments for operating leases by $607.9 million). In addition, $98.8 million was generated from the March 1995 issuance of $100 million in senior unsecured 8% Notes due 2005. These proceeds were primarily used to finance aircraft-related capital expenditures and to provide working capital.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 1996

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION Southwest Airlines Co. (Southwest) is a major domestic airline that provides shorthaul, high frequency, point-to-point, low-fare service. The consolidated financial statements include the accounts of Southwest and its wholly owned subsidiaries (the Company). All significant intercompany balances 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 amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. Certain prior year amounts have been reclassified for comparison purposes.

CASH AND CASH EQUIVALENTS Cash equivalents consist of certificates of deposit and investment grade commercial paper issued by major corporations and financial institutions that are highly liquid and have original maturity dates of three months or less. Cash and cash equivalents are carried at cost, which approximates market value.

INVENTORIES Inventories of flight equipment expendable parts, materials, and supplies are carried at average cost. These items are charged to expense when issued for use.

PROPERTY AND EQUIPMENT Depreciation is provided by the straight-line method to residual values over periods ranging from 12 to 20 years for flight equipment and 3 to 30 years for ground property and equipment. Property under capital leases and related obligations are recorded at an amount equal to the present value of future minimum lease payments computed on the basis of the Company's incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under capital leases is on a straight-line basis over the lease term and is included in depreciation expense. In accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of", the Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows to be generated by those assets are less than the carrying amounts of those assets.

AIRCRAFT AND ENGINE MAINTENANCE The cost of engine overhauls and routine maintenance costs for aircraft and engine maintenance

25

are charged to maintenance expense as incurred. Scheduled airframe overhaul costs are capitalized and amortized over the estimated period benefited, presently 8 years. Modifications that significantly enhance the operating performance or extend the useful lives of aircraft or engines are capitalized and amortized over the remaining life of the asset.

REVENUE RECOGNITION Passenger revenue is recognized when transportation is provided. Tickets sold but not yet used are included in "Air traffic liability", which includes estimates that are evaluated and adjusted periodically. Any adjustments resulting therefrom are included in results of operations for the periods in which the evaluations are completed.

FREQUENT FLYER AWARDS The Company accrues the estimated incremental cost of providing free travel awards earned under its Rapid Rewards frequent flyer program.

ADVERTISING The Company expenses the production costs of advertising as incurred. Advertising expense for the years ended December 31, 1996, 1995, and 1994 was $109,136,000, $92,087,000, and $79,475,000, respectively.

STOCK-BASED EMPLOYEE COMPENSATION Pursuant to Statement of Financial Accounting Standards No. 123 (SFAS 123) "Accounting for Stock-Based Compensation", the Company accounts for stock-based compensation plans utilizing the provisions of Accounting Principles Board Opinion No. 25 (APB 25), "Accounting for Stock Issued to Employees" and related Interpretations because, as discussed in Note 7, the alternative fair value accounting provided for under SFAS 123 requires use of option valuation models that were not developed for use in valuing employee stock options.

2. COMMITMENTS

The Company's contractual purchase commitments consist primarily of scheduled aircraft acquisitions. Timing of payments pursuant to contractual commitments was affected favorably by third quarter 1995 amendments to certain aircraft purchase contracts, which modified future progress payment schedules. Fifteen 737-300 and four 737-700 aircraft are scheduled for delivery in 1997. Sixteen
- - -700s are scheduled for delivery in 1998, 16 in 1999, 15 in 2000, and 12 in 2001. In addition, the Company has options to purchase up to sixty-seven -700s during 1998-2004. The Company has the option, which must be exercised two years prior to the contractual delivery date, to substitute 737-600s or 737-800s for the -700s delivered subsequent to 1999. Aggregate funding needed for these commitments is approximately $1,960.1 million, subject to adjustments for inflation, due as follows: $515.1 million in 1997,

26

$420.0 million in 1998, $502.2 million in 1999, $318.3 million in 2000, and $204.5 million in 2001.

The Company has historically used jet fuel and heating oil fixed price swap arrangements to hedge its exposure to price fluctuations on an insignificant percent of its annual fuel requirements. As of December 31, 1996, the Company had no open swap agreements, although the hedging program has not been discontinued. As of December 31, 1995, the Company had a heating oil swap agreement with a broker-dealer to exchange monthly payments on a notional quantity of 1,050,000 gallons during May 1996. Under the swap agreement, the Company paid or received the difference between the daily average heating oil price and a fixed price of $.46 per gallon.

The Company's principal hedging program utilizes the purchase of crude oil call options at a nominal premium and at volumes of up to 30 percent of its annual fuel requirements.

Gains and losses on hedging transactions are recorded as adjustments to fuel expense and have been insignificant. Any such future agreements expose the Company to credit loss in the event of nonperformance by the other parties to the agreements. The Company does not anticipate such nonperformance.

The aircraft leases can generally be renewed, at rates based on fair market value at the end of the lease term, for one to five years. Most aircraft leases have purchase options at or near the end of the lease term at fair market value, but generally not to exceed a stated percentage of the lessor's defined cost of the aircraft.

6. COMMON STOCK

At December 31, 1996, the Company had common stock reserved for issuance pursuant to Employee stock benefit plans (35,257,962 shares) and upon exercise of rights (180,370,052 shares) pursuant to the Common Stock Rights Agreement, as amended (Agreement).

Effective July 18, 1996, the Company amended and restated the Agreement. The principal purpose of the amendment and restatement was to extend the Agreement by 10 years. Pursuant to the Agreement, each outstanding share of the Company's common stock is accompanied by one common share purchase right (Right). Each Right entitles its holder to purchase one share of common stock at an exercise price of $16.67 and is exercisable only in the event of a proposed takeover, as defined by the Agreement. The Company may redeem the Rights at $.0111 per Right prior to the time that 15 percent of the common stock has been acquired by a person or group. If the Company is acquired, as defined in the Agreement, each Right will entitle its holder to purchase for $16.67 that number of the acquiring company's or the Company's common shares, as provided in the Agreement, having a market value of two times the exercise price of the Right. The Rights will expire no later than July 30, 2006.

7. STOCK PLANS

At December 31, 1996, the Company had six stock-based compensation plans and other stock options outstanding, which are described below. The Company applies APB 25 and related Interpretations in accounting for its stock-based compensation. Accordingly, no compensation cost is recognized for its fixed option plans because the exercise prices of the Company's Employee stock options equal the market prices of the underlying stock on the date of the grants. Compensation cost charged against income for other options outstanding was $649,778, $564,251, and $451,400 for 1996, 1995, and 1994, respectively.

The Company has five fixed option plans. Under the 1991 Incentive Stock Option Plan, the Company may grant options to key Employees for up to 9,000,000 shares of common stock. Under the 1991 Non-Qualified Stock Option Plan, the Company may grant options to key Employees and non-employee directors for up to 750,000 shares of common stock. All options granted under these plans have ten-year maximum terms and vest and become fully exercisable at the end of three, five, or ten years of continued employment, depending upon the grant type.

Under the 1995 Southwest Airlines Pilots' Association Non-Qualified Stock Option Plan (SWAPA Plan), the Company may grant

31

options to Pilots for up to 18,000,000 shares of common stock. An initial grant of approximately 14,500,000 shares was made on January 12, 1995 at an option price of $20.00 per share, which exceeded the market price of the Company's stock on that date. Options granted under the initial grant vest in ten annual increments of ten percent. On September 1 of each year of the agreement, beginning September 1, 1996, additional options will be granted to Pilots that become eligible during that year. Additional options granted on September 1, 1996 vest in eight annual increments of 12.5 percent. Options under both grants must be exercised prior to January 31, 2007, or within a specified time upon retirement or termination. In the event that the Southwest Airlines Pilots' Association exercises its option to make the collective bargaining agreement amendable on September 1, 1999, any unexercised options will be canceled on December 1, 1999.

Under the 1996 Incentive Stock Option Plan, the Company may grant options to key Employees for up to 6,000,000 shares of common stock. Under the 1996 Non-Qualified Stock Option Plan, the Company may grant options to key Employees and non-employee directors for up to 575,000 shares of common stock. All options granted under these plans have ten-year terms and vest and become fully exercisable at the end of three, five, or ten years of continued employment, depending upon the grant type.

Under all fixed option plans, except the SWAPA Plan, the exercise price of each option equals the market price of the Company's stock on the date of grant. Under the SWAPA Plan, for additional options granted each September 1, eligible Pilots will be required to pay a purchase price equal to 105 percent of the fair value of such stock on the date of the grant.

The Company has granted options to purchase the Company's common stock related to employment contracts with the Company's president and chief executive officer. These options have terms of ten years from the date of grant or ten years from the date exercisable, depending upon the grant. The options vest and become fully exercisable over three or four years. In 1996, the Company granted 144,395 options with an exercise price of $1.00 per share and 500,000 options with an exercise price of $23.50 per share related to the 1996 employment agreement. None of the 1996 options granted were exercised in 1996, however, 128,879 were exercisable as of December 31, 1996. At December 31, 1996, 1995, and 1994, 1,897,898, 1,422,253, and 1,489,753 total options were outstanding. Exercise prices range from $1.00 to $23.50 per share. Options for 168,750, 67,500, and 15,000 shares were exercised in 1996, 1995, and 1994, respectively.

Under the 1991 Employee Stock Purchase Plan (ESPP), the Company is authorized to issue up to a balance of 1,183,236 shares of common stock to Employees of the Company at a price equal to 90 percent of the market value at the end of each purchase period. Common stock purchases are paid for through periodic payroll deductions. Participants under the plan received 309,446 shares in 1996, 388,339 shares in 1995, and 290,054 shares in 1994 at average prices of $23.05, $19.18, and $24.98, respectively.

Pro forma information regarding net income and net income per share is required by SFAS 123, and has been determined as if the Company had accounted for its employee stock-based compensation plans and other stock options under the fair value method of that SFAS. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants under the fixed option plans in 1996 and 1995, respectively: dividend yield of .16% and .21%; expected volatility of 35.4% and 36.9%; risk-free interest rate of 5.9% and 7.8%; and expected lives of 5.0 years for both periods. Assumptions for the stock options granted in 1996 to the Company's president and chief executive officer were the same as for the fixed option plans except for the weighted average expected lives of 8.0 years.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company's Employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its Employee stock options.

For purposes of pro forma disclosures the estimated fair value of stock-based compensation plans and other options is amortized to expense primarily over the vesting period. The Company's pro forma net income and net income per share is as follows (in thousands except per share amounts):

                                                       1996              1995
                                                       ----              ----
Net income                 As reported               $207,337          $182,626
                           Pro forma                 $196,478          $167,907

Net income per share       As reported                  $1.37             $1.23
                           Pro forma                    $1.33             $1.14

The effects of applying SFAS 123 for providing pro forma disclosures during the initial phase-in period may not be representative of the effects on reported net income for future years.

The weighted-average fair value of options granted under the five fixed option plans during 1996 and 1995 was $10.17 and $8.42, respectively, for the incentive plans, $9.24 and $7.97, respectively, for the SWAPA Plan, and $10.17 and $8.42,

35

respectively, for other non-qualified plans. The weighted average fair value of options granted in 1996 to the Company's president and chief executive officer (no options were granted in 1995) was $13.98. The weighted-average fair value of each purchase right under the ESPP granted in 1996 and 1995, which is equal to the ten percent discount from the market value of the common stock at the end of each purchase period, was $2.56 and $2.15, respectively.

8. EMPLOYEE PROFITSHARING AND SAVINGS PLANS

Substantially all of Southwest's Employees are members of the Southwest Airlines Co. Profitsharing Plan (the Plan). Total profitsharing expense charged to operations in 1996, 1995, and 1994, was $59,927,000, $54,033,000, and $52,782,000, respectively.

The Company sponsors Employee savings plans under Section 401(k) of the Internal Revenue Code. The plans cover substantially all full-time Employees. The amount of matching contributions varies by Employee group. Company contributions generally vest over five years with credit for prior years' service granted. Company matching contributions expensed in 1996, 1995 and 1994 were $35,125,000, $28,954,000, and $19,817,000, respectively.

Southwest has received examination reports from the Internal Revenue Service
proposing certain adjustments to Southwest's income tax returns for 1987
through 1991. The adjustments relate to certain types of aircraft financings
consummated by Southwest, as well as other members of the aviation industry
during that time period. Southwest intends to vigorously protest the
adjustments proposed with which it does not agree. The industry's difference
with the IRS involves complex issues of law and fact that are likely to take a
substantial period of time to resolve. Management believes that final
resolution of such protest will not have a materially adverse effect upon the
results of operations of Southwest.

The effective tax rate on income before income taxes differed from the federal
income tax statutory rate for the following reasons (in thousands):

                                 1996                1995               1994

10. NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE

Net income per common and common equivalent share is computed based on the weighted-average number of common and common equivalent shares outstanding (151,793,477 in 1996, 148,850,512 in 1995 and 147,305,374 in 1994). Fully diluted earnings per share have not been presented as the fully dilutive effect of shares issuable upon the exercise of options under the Company's Stock Option Plans is not material.

- 7 -

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided by the Board of Directors and set forth in such Officers' Certificate or as may be otherwise provided in any such indenture supplemental hereto.

SECTION 2.04. Authentication and Delivery of Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Securities to or upon the written order of the Company, signed on behalf of the Company by its Chairman of the Board or its President or a Vice Chairman of the Board or a Vice President and attested to by its Secretary or an Assistant Secretary or by its Treasurer or an Assistant Treasurer, without any further action by the Company. In authenticating such Securities and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to
Section 6.01) shall be fully protected in relying upon:

(1) certified copies of the Articles of Incorporation and bylaws of the Company (or an Officers' Certificate with respect to any amendment thereto) and of any resolutions of the Board of Directors authorizing the action taken pursuant to the resolutions delivered pursuant to clause (2) below;

- 8 -

(c) that all laws and requirements in respect of the execution and delivery by the Company of the Securities have been complied with; and

(d) such other matters as the Trustee may reasonably request.

The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken by the Company or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Securityholders.

SECTION 2.05. Execution of Securities. The Securities shall be signed on behalf of the Company, manually or in facsimile, by its Chairman of the Board or its President or a Vice Chairman of the Board or a Vice President under its corporate seal (which may be in facsimile) reproduced thereon and attested, annually or in facsimile, by its Secretary or an Assistant Secretary or its Treasurer or an Assistant Treasurer. Typographical and other minor errors or defects in any such reproduction of the seal or any such signature shall not affect the validity or enforceability of any Security that has been duly authorized and delivered by the Trustee.

In case any officer of the Company whose signature appears on any of the Securities, annually or in facsimile, shall cease to be such officer before such Securities so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Securities nevertheless may be authenticated and delivered by the Trustee, or disposed of by the Company, such Securities nevertheless may be authenticated and delivered or disposed of as though the person whose signature appears on such Securities had not ceased to be such officer of the Company; and any Security may be signed and the corporate seal reproduced thereon may be attested, on behalf of the Company, annually or in facsimile, by such persons as, at the actual date of the execution of such Security, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such officer.

Only such Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore receipted, signed manually by an authorized signatory of the Trustee, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Security executed by the Company shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

SECTION 2.06. Exchange of Securities. Securities of any series may be exchanged for a like aggregate principal amount of Securities of the same series in other authorized denominations. The Securities of any series to be exchanged shall be surrendered at the offices or agencies to be maintained by the Company in accordance with the provisions of Section 3.02, and the Company shall execute and the Trustee shall authenticate and deliver in

No service charge shall be made for any exchange or registration of transfer of Securities, but the Company or the Securities registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

The Company shall not be required to exchange or register a transfer of
(i) any Securities of any series for a period of 15 days next preceding the first mailing of notice of redemption of Securities of such series to be redeemed, or (ii) any Securities selected, called or being called for redemption except, in the case of any Security where public notice has been given that such Security is to be redeemed in part, the portion thereof not so to be redeemed.

Notwithstanding the foregoing, any Global Security shall be exchangeable pursuant to this Section 2.06 for Securities registered in the names of persons other than the Depositary for such Security or its nominee only if (i) such Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and the Company fails to appoint a successor Depositary for such Global Security within 90 days after the Company receives such notice or becomes aware of such event, (ii) the Company executes and delivers to the Trustee written instructions that such Global Security shall be so exchangeable, or (iii) there shall have occurred and be continuing an Event of Default or an event which, with the giving of notice or lapse of time, or both, would constitute an event of Default with respect to the Securities. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as the Depositary shall direct.

- 10 -

Except as provided in the immediately preceding paragraph, a Global Security may not be transferred except as a whole by the Depositary with respect to such Global Security to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor of such Depositary or a nominee of such successor.

None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

SECTION 2.07. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute and the Trustee authenticate and deliver temporary Securities of such series (printed, typewritten or otherwise reproduced) of any authorized denomination and substantially in the form of the definitive Securities of such series, but with such omission, insertions and variations as may be appropriate for temporary Securities of such series, all as may be determined by the Company. Temporary Securities of any series may contain reference to any provisions of the Indenture as may be appropriate. Every such temporary Security shall be authenticated by the Trustee upon the conditions and in substantially the same manner, and with the same effect, as the definitive Securities of such series. Without unnecessary delay, the Company will execute and deliver to the Trustee definitive Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefor, at the offices or agencies to be maintained by the Company in accordance with the provisions of Section 3.02, and the Trustee shall authenticate and deliver in exchange for such temporary Securities of such series an equal aggregate principal amount of definitive Securities of such series. Until so exchanged, the temporary Securities of such series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder.

SECTION 2.08. Mutilated, Destroyed, Lost or Stolen Securities. In case any temporary or definitive Security of any series shall become mutilated or be destroyed, lost or stolen, the Company, in the case of any mutilated Security of any series shall, and in the case of any destroyed, lost or stolen Security of any series in its discretion may, execute and upon its request the Trustee shall authenticate and deliver, a new Security of the same series bearing a number not contemporaneously outstanding in exchange and substitution for the mutilated Security, or in lieu of and substitution for the Security so destroyed, lost or stolen, or, if any such Security shall have matured or shall be about to mature, instead of issuing a substituted Security, the Company may pay the same without surrender thereof except in the case of a mutilated Security.

In every case the applicant for a substituted Security or for such payment shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save

- 11 -

each of them harmless from all risk, however remote, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. the Trustee may authenticate any such substituted Security and deliver the same, or the Trustee or any Paying Agent of the Company may make any such payment, upon the written request or authorization of any officer of the Company, and shall incur no liability to anyone by reason of anything done or omitted to be done by it in good faith under the provisions of this Section 2.08. Upon the issue of any substituted Security, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any expenses connected therewith (including the fees and expenses of the Trustee).

Every substituted Security issued pursuant to the provisions of this
Section 2.08 in substitution for any destroyed, lost or stolen Securities shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities, and shall preclude (to the extent lawful) any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

SECTION 2.09. Cancellation of Surrendered Securities. All Securities surrendered for the purpose of payment, redemption, exchange, substitution or registration of transfer, shall, if surrendered to the Company or any Paying Agent or registrar, be delivered to the Trustee and the same, together with securities surrendered to the Trustee for cancellation, shall be promptly canceled by it, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall destroy canceled Securities and shall deliver certificates of destruction thereof to the Company from time to time. If the Company shall purchase or otherwise acquire any of the Securities, however, such purchase or acquisition shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee for cancellation.

SECTION 2.10. Securities in Global Form. If Securities of or within a series are issuable in whole or in part in temporary or permanent global form, as specified as contemplated by Section 2.03, then, notwithstanding clause (8) of Section 2.03, any such Security shall represent such of the outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may

- 12 -

from time to time be reduced to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, or changes in the rights of holders, of outstanding Securities represented thereby, shall be made by the Trustee in such manner and upon instructions given by such person or persons as shall be specified therein or in the instructions by the Company to be delivered to the Trustee pursuant to
Section 2.04 or 2.07. Subject to the provisions of Section 2.04 and, if applicable, Section 2.07, the Trustee shall deliver and redeliver any Security in global form in the manner and upon instructions given by the person or persons specified therein or in the applicable Company instructions. Any instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 13.05 hereof and need not be accompanied by an Opinion of Counsel.

Each payment from the Company to the Trustee or to the Paying Agent shall be accompanied by a written notice that designates the series to which such payment relates. As a condition precedent to the payment of any interest on a Security, the Company or the Paying Agent may require the holder of such Security to furnish such evidence as will enable the Company to determine whether it is required by law to deduct or to retain any tax or taxes from the interest so payable. An installment of principal or interest shall be considered paid on the date it is due if the trustee or Paying Agent holds on that date money designated for and sufficient to pay the installment.

SECTION 3.02. Maintenance of Office or Agency for Registration of Transfer, Exchange and Payment of Securities. So long as any of the Securities shall remain outstanding, the Company will maintain an office or agency in the City of Dallas, Texas, where the Securities may be surrendered for exchange or registration of transfer as in this Indenture provided, and where notices and demands to or upon the Company in respect of the Securities or of this Indenture may be served, and where the Securities may be presented or surrendered for payment. The Company will give to the Trustee prompt written notice of the location of any such office or agency and of any change of location thereof. In case the Company shall fail to maintain any such required office or agency or shall fail to give such notice of the location or of any change in the location thereof, such surrenders, presentations and demands may be made and notices may be served at the principal office of the Trustee, and the Company hereby appoints the Trustee its agent to receive at the aforesaid office all such surrenders, presentations, notices and demands.

- 13 -

The Company may from time to time designate one or more other offices or agencies (in or outside of the City of Dallas) where the Securities may be presented or surrendered for any or all such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the City of Dallas, for such purposes as stated in this Section. The Company will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such office or agency.

SECTION 3.03. Appointment to Fill a Vacancy in the Office of Trustee. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so that there shall at all times be a Trustee hereunder.

(2) that it will give the Trustee written notice of any failure by the Company (or by any other obligor on any series of Securities) to make any payment of the principal of (and premium, if any) or interest on such series of Securities when the same shall be due and payable; and

(c) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of (and premium, if any) or interest on any series of Securities, set aside,

- 14 -

segregate and hold in trust for the benefit of the persons entitled thereto, a sum sufficient to pay such principal (and premium, if any) or interest so becoming due until such sums shall be paid to such persons or otherwise disposed of as herein provided and will promptly notify the Trustee in writing of any such action or failure to take such action.

(d) default under the terms of any agreement or instrument evidencing, or under which the Company has at the date of this Indenture or hereafter outstanding, any indebtedness for borrowed money and such indebtedness shall be accelerated so that the same shall be or become due and payable prior to the date on which the same would otherwise become due and payable and the aggregate principal amount thereof so accelerated exceeds $50,000,000 and such acceleration is not rescinded or annulled within ten days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the holders of at least 25% in aggregate principal amount of the outstanding securities of that series a written notice specifying such default and stating that such notice is a "Notice of Default" hereunder; (it being understood however, that, subject to the provisions of Section 6.01, the Trustee shall not be deemed to have knowledge of such default under such agreement or instrument unless either (A)

- 18 -

a Responsible Officer of the Trustee shall have actual knowledge of such default or (B) a Responsible Officer of the Trustee shall have received written notice thereof from the Company, from any Holder, from the holder of any such indebtedness or from the trustee under any such agreement or other instrument); provided, however, that if such default under such agreement or instrument is remedied or cured by the Company or waived by the holders of such indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived without further action upon the part of either the Trustee or any of such Holders;

(e) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Company or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or

- 19 -

with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of such series (or of all the Securities, as the case may be) and the principal of (and premium, if any, on) all Securities of such series (or of all the Securities, as the case may be) that shall have become due otherwise than by declaration (with interest on overdue installments of interest to the extent permitted by law, and on such principal and premium, if any, at the rate of interest borne by the Securities or Yield to Maturity (in the case of Original Issue Discount Securities) applicable to the Securities of such series (or at the respective rates of interest or Yields to maturity of all the Securities, as the case may be) to the date of such payment or deposit) and the expenses of the Trustee, and any and all defaults under the Indenture, other than the nonpayment of principal of and accrued interest on Securities that shall have become due by declaration, shall have been remedied--then and in every such case the Securityholders of a majority in aggregate principal amount of the Securities of such series (or of all the Securities, as the case may be) then outstanding, by written notice to the Company and to the Trustee, may waive all defaults with respect to that series, each such series voting as a separate class (or with respect to all Securities, as the case may be, in such case treated as a single class) and rescind and annul such declaration and its consequences; but no such waiver of rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Trustee and the holders of the Securities of such series shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceedings had been taken.

SECTION 5.02. Payment of Securities on Default; Suit Therefor. The Company covenants that (1) in case default shall be made in the payment of any installment of interest on any of the Securities of any series, as and when the same shall become due and payable, and such default shall have continued for a period of 30 days or (2) in case default shall be made in the payment of the principal of any of the Securities of any series when the same shall have become due and payable, whether upon maturity of the Securities for such series or otherwise, including any sinking fund payment--then, upon demand of the Trustee, the Company will pay to the Trustee for the benefit of the holders of the Securities of such series (and shall designate which series) the whole amount that then shall have become due and payable on all Securities of such series for principal (and premium, if any) or interest, or both, as the case may be, with interest on the overdue principal (and premium, if any) and installments of interest (to the extent permitted by law) at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) borne by such series of Securities; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including a reasonable

- 20 -

compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or bad faith.

Until such demand is made by the Trustee, the Company may pay the principal of and interest on the Securities of any series to the holders thereof, whether or not the Securities of such series be overdue.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor upon such Securities, and collect in the manner provided by law out of the property of the Company or any other obligor upon such Securities wherever situated the moneys adjudged or decreed to be payable.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor upon the Securities of any series under the Bankruptcy Code or any other applicable law or in connection with the insolvency of the Company or any other obligor upon any Securities or in the case a receiver or trustee shall have been appointed for its property, or in case of any other judicial proceedings relative to the Company or any other obligor upon such series of Securities or to creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of such series of Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 5.02, shall be entitled and empowered by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest (or if the Securities of any series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) owing and unpaid in respect of the Securities of any series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trust and of the Securityholders allowed in any judicial proceedings relative to the Company or any other obligor upon the Securities of any series, its creditors, or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of such holders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the holders, to pay to the Trustee any amount due it for compensation and expenses, including counsel fees incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, liabilities and counsel fees out of the estate in any such proceedings shall be denied for any reason (except as a result of negligence or bad faith), payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, moneys, securities and

- 21 -

other property that the holders of the Securities of any series may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

All rights of action and of asserting claims under this Indenture, or under any of the Securities of any series, may be enforced by the Trustee without the possession of any of the Securities, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall be for the ratable benefit of the holders of the Securities and the Trustee.

SECTION 5.03. Application of Moneys Collected by Trustee. Any moneys collected by the Trustee pursuant to Section 5.02 with respect to any one or more series shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys, and, in the case of the distribution of such moneys on account of principal or interest, upon presentation of the several Securities of a series in respect of which moneys have been collected, and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange for the presented Securities of such series if only partially paid, and upon surrender thereof if fully paid:

FOURTH: To the payment of the remainder, if any, to the Company, its successors or assigns, or to whosoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

SECTION 5.04. Limitation on Suits by Holders of Securities. No holder of a Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law or in bankruptcy or otherwise, upon or under or with respect to this Indenture or for the appointment of a receiver, liquidating custodian, trustee or similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as hereinabove provided, and unless also the holders of not less than 25% in aggregate principal amount of such series of Securities then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 5.06; it being understood and intended, and being expressly covenanted by the holder of every Security of a series with every other Securityholder and the Trustee, that no one or more holders of such series of Securities shall have any right in any manner whatsoever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other series of Securities, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Securities. For the protection and enforcement of the provisions of this Section 5.04, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provisions in this Indenture, the right of any holder of any Security to receive payment of the principal of (and premium, if any) and interest on such Security, on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such holder.

SECTION 5.05. Proceedings by Trustee; Remedies Cumulative and Continuing. In case an Event of Default has occurred, has not been waived, and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. All powers and remedies given by this Article Five to the Trustee or to the Securityholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or any other powers and remedies available to the Trustee or to the holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and

- 23 -

agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power accruing upon any default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein; and, subject to the provisions of Section 5.04, every power and remedy given by this Article Five or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders.

SECTION 5.06. Rights of Holders of Majority in Principal Amount of Securities to Direct Trustee and to Waive Defaults. The holders of a majority in aggregate principal amount of the Securities of all series affected (voting as one class) at the time outstanding (determined as provided in Section 7.04), or, if a record date is set in accordance with Section 7.05, as of such record date, shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee by the Indenture with respect to the Securities of such series; provided, however, that subject to the provisions of Section 6.01, the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel shall determine that the action so directed may not lawfully be taken, or if the Trustee in good faith shall, by a responsible officer or officers of the Trustee, determine that the proceedings so directed would be illegal or involve it in personal liability or be unjustly prejudicial to the Securityholders not consenting, and provided further that nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction by the Securityholders. Prior to the declaration of the maturity of the Securities of any series as provided in
Section 5.01, the holders of a majority in aggregate principal amount of the Securities of such series at the time outstanding (each such series voting as a separate class) (determined as provided in Sections 7.04 and 7.05) may on behalf of the holders of all of the Securities of such series waive any past default hereunder and its consequences, except a default in the payment of interest or premium on, or the principal of, any of the Securities. In the case of any such waiver the Company, the Trustee and the holders of the Securities of such series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent hereon.

SECTION 5.07. Trustee to Give Notice of Defaults Known to It, But May Withhold in Certain Circumstances. The Trustee shall, within 90 days after the occurrence of a default hereunder, give to the Securityholders, in the manner and to the extent provided in subsection (c) of Section 4.04 with respect to reports pursuant to subsection (a) of Section 4.04, notice of such defaults known to the Trustee unless such default shall have been cured or waived before the giving of such notice (the term "defaults" for the purposes of this Section 5.07 being hereby defined to be the events specified in clauses (a), (b), (c),
(d), (e) and (f) of Section 5.01, not including any periods of grace provided for therein, and irrespective of the giving of any required notice); provided that, except in the case of default in the payment of the principal of (and premium, if any) or interest on any of the Securities of such series, the Trustee shall be protected

- 24 -

in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determined that the withholding of such notice is in the interest of the Securityholders of such series.

SECTION 5.08. Requirement of an Undertaking to Pay Costs in Certain Suits Under the Indenture or Against the Trustee. All parties to this Indenture agree, and each holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement or any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney's fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this
Section 5.08 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders of any series, holding in the aggregate more than ten percent in aggregate principal amount of the Securities of such series outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of (and premium, if any) or interest on any Security, on or after the due date expressed in such Security.

ARTICLE SIX

CONCERNING THE TRUSTEE

SECTION 6.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred with respect to the Securities of a series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred of which a Responsible Officer of the Trustee has actual knowledge (which has not been cured or waived) the Trustee shall exercise such of the rights and powers vested in it by this Indenture with respect to the Securities of a series, and use the same degree of care and skill in their exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, provided, however, that:

(a) prior to the occurrence of an Event of Default with respect to the Securities of any series and after the curing or waiving of all Events of default with respect to such series that may have occurred

- 25 -

(1) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall only be liable for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Securities of all series affected (voting as a class) at the time outstanding (determined as provided in Sections 7.04 and 7.05) relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if there is reasonable grounds for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

SECTION 6.02. Reliance on Documents, Opinions, etc. Subject to the provisions of Section 6.01:

(a) The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, note or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

- 26 -

(b) Any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers' Certificate (unless other evidence in respect thereof be herein specifically prescribed); and the Trustee by a copy thereof certified by the Secretary or any Assistant Secretary of the Company;

(c) The Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(d) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Securityholders, pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that may be incurred therein or thereby; but nothing herein contained shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs;

(e) The Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order approval, bond, note or other paper or document, unless requested in writing so to do by the holders of not less than a majority in aggregate principal amount of the Securities of all series affected then outstanding voting as one class (determined as provided in Sections 7.04 and 7.05); provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expense or liability as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand; and

(g) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys. The Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

- 27 -

SECTION 6.03. No Responsibility for Recitals, etc. The statements and recitals contained herein and in the Securities and in any other document in connection with the sale of the Securities (other than the certificate of authentication of the Securities) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds of such Securities, or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture, or for the use or application of any moneys received by any Paying Agent other than the Trustee.

SECTION 6.04. Trustee, Paying Agent or Security Registrar May Own Securities. The Trustee or any Paying Agent or Security registrar, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee, Paying Agent or Security registrar.

SECTION 6.05. Moneys Received by Trustee to be Held in Trust Without Interest. Subject to the provisions of Section 11.04, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on moneys received by it hereunder except such as it may agree with the Company to pay thereon. So long as no Event of Default shall have occurred and be continuing, all interest allowed on any such moneys shall be paid from time to time upon the written order of the Company, signed by its Chairman of the Board, any Vice Chairman of the Board, its President or any Vice President or its Treasurer or any Assistant Treasurer.

SECTION 6.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a Trustee of an express trust), and the Company will promptly pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in connection with the acceptance or administration of its trust under this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Company also covenants to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Trustee and arising
(a) out of or in connection with the acceptance or administration of this trust, or (b) from any action or failure to act as authorized or within the discretion or rights or powers conferred upon the Trustee hereunder, including the costs and expenses of defending itself against any claim of liability in the premises. The obligations of the Company under this Section 6.06 to compensate the Trustee and to pay or reimburse the Trustee

- 28 -

for expenses, disbursements, losses, liabilities and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such additional indebtedness shall be secured by a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Securities.

SECTION 6.07. Right of Trustee to Rely on Officers' Certificate Where No Other Evidence Specifically Prescribed. Subject to the provisions of Section 6.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers' Certificate delivered to the Trustee, and such Certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof.

SECTION 6.08. Conflicting Interest of Trustee. (a) If the Trustee has or shall acquire any conflicting interest, as defined in this Section 6.08, it shall, within 90 days after ascertaining that it has such conflicting interest, either eliminate such conflicting interest or, unless the Trustee's duty to resign is stayed as provided in Section 310(b) of the Trust Indenture Act of 1939, resign in the manner and with the effect specified in Section 6.10, such resignation to become effective upon the appointment of a successor trustee and such successor's acceptance of such appointment, and the Company shall take prompt steps to have a successor appointed in the manner provided in Section 6.10.

(b) In the event that the Trustee shall fail to comply with the provisions of subsection (a) of this Section 6.08, the Trustee shall, within 10 days after the expiration of such 90-day period, or, if the Trustee's duty to resign is stayed, after the end of such stay, transmit notice of such failure to the Securityholders in the manner and to the extent provided in subsection
(c) of Section 4.04 with respect to reports pursuant to subsection (a) of
Section 4.04.

(c) For the purposes of this Section 6.08, the Trustee shall be deemed to have a conflicting interest if the Trustee has a conflict within the provisions of Section 310(b) of the Trust Indenture Act of 1939.

SECTION 6.09. Requirements for Eligibility of Trustee. The Trustee hereunder shall at all times be a corporation organized and doing business under the laws of the United States or any State or territory thereof or of the District of Columbia authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least five million dollars, subject to supervision or examination by Federal, State, Territorial, or District of Columbia authority. If such corporation publishes reports of condition at least annually, pursuant

- 29 -

to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 6.09, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 6.09, the Trustee shall resign immediately in the manner and with the effect specified in Section 6.10. Neither the Company nor any persons directly or indirectly controlling, controlled by, or under common control with the Company shall serve as Trustee.

SECTION 6.10. Resignation or Removal of Trustee. (a) The Trustee, or any Trustee hereafter appointed, may at any time resign with respect to one or more series of Securities by giving written notice of such resignation to the Company or to the Securityholders, such notice to the Securityholders of applicable series of Securities to be given by mailing (by first class mail) the same. Upon receiving such notice of resignation, the Company shall promptly appoint a successor Trustee with respect to the applicable series by written instrument, in duplicate, executed by order of the Board of Directors of the Company, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Securityholder who has been a bona fide holder of a Security or Securities for at least six months may, subject to the provisions of Section 5.08, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(1) the Trustee shall fail to comply with the provisions of subsection (a) of Section 6.08 with respect to any series of Securities after written request therefor by the Company or by any Securityholder who has been a bona fide holder of a Security or Securities of such series for at least six months, or

(2) the Trustee shall cease to be eligible in accordance with the provisions of Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Securityholder, or

(3) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of a substantial portion of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of a substantial portion of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, the Company may remove the Trustee with respect to the applicable series and appoint a successor trustee for such series by written instrument, in duplicate, executed by order of the Board of Directors

- 30 -

of the Company, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 5.08, any Securityholder who has been a bona fide holder of a Security or Securities of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The holders of a majority in aggregate principal amount of the Securities of all series at the time outstanding voting as one class (determined as provided in Section 7.04) may at any time remove the Trustee with respect to Securities of all series and appoint a successor trustee with respect to securities of all series by written instrument or instruments signed by such holders or their attorneys-in-fact duly authorized, or by the affidavits of the permanent chairman and secretary of a meeting of the Securityholders evidencing the vote upon a resolution or resolutions submitted thereto with respect to such removal and appointment (as provided in Article Eight), and by delivery thereof to the Trustee so removed, to the successor trustee and to the Company.

(d) Any resignation or removal of the Trustee and appointment of any successor trustee pursuant to any of the provisions of this Section 6.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 6.11.

SECTION 6.11. Acceptance by Successor to Trustee; Notice of Succession of a Trustee. Any successor trustee appointed as provided in Section 6.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee with respect to all or any particular series shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations with respect to such series of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 6.06, pay over to the successor trustee, subject to Section 11.04, all monies at the time held by it hereunder with respect to such series, and execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 6.06.

- 31 -

If a successor trustee is appointed with respect to the Securities of one or more (but not all) series, the Company, the predecessor Trustee and each successor trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto that shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees as co-trustees of the same trust and that each such Trustee shall be Trustee of a trust or trusts under separate indentures.

No successor trustee with respect to any series of Securities shall accept appointment as provided in this Section 6.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of
Section 6.08 and eligible under the provisions of Section 6.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 6.11, the Company shall mail to the holders of Securities of any series by first-class mail notice thereof. If the Company fails to mail such notice within 30 days after acceptance of appointment by the successor trustee, the successor trustee shall, in its discretion, cause such notice to be mailed at the expense of the Company.

SECTION 6.12. Successor to Trustee by Merger, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger or conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be qualified under the provisions of Section 6.08 and eligible under the provisions of Section 6.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture and the Securities of any series shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so authenticated; and in case at that time the Securities of any series shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificates shall have the full force that it is anywhere in the Securities of such series or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Securities of any series in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

- 32 -

SECTION 6.13. Limitations on Rights of Trustee as a Creditor. The Trustee shall comply with Section 311 of the Trust Indenture Act of 1939.

ARTICLE SEVEN

CONCERNING THE SECURITYHOLDERS

SECTION 7.01. Evidence of Action by Securityholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Securities of any or all series may take any action (including the making of any demand or request, the giving of any notice, consent, or waiver or the taking of any other action) the fact that the holders of such specified percentage, determined as of the time such action was taken or, if a record date was set with respect thereto pursuant to Section 7.05, as of such record date, have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Securityholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Securities voting in favor thereof at any meeting of Securityholders duly called and held in accordance with the provisions of Article Eight, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Securityholders.

SECTION 7.02. Proof of Execution of Instruments and of Holding of Securities. Subject to the provisions of Sections 6.01, 6.02 and 8.05, proof of the execution of any instrument by a Securityholder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee.

The ownership of Securities shall be proved by the register of such Securities, or by a certificate of the registrar thereof.

The Trustee may accept such other proof or require such additional proof of any matter referred to in this Section 7.02 as it shall deem reasonable.

The record of any Securityholders' meeting shall be proved in the manner provided in Section 8.06.

SECTION 7.03. Who May be Deemed Owners of Securities. The Company, the Trustee, any Paying Agent and any Security registrar may deem and treat the person in whose name any Security shall be registered upon the books of the Company for such series on the applicable record date as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of, premium, if any, and interest on such Security and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Security registrar shall be affected by any notice to the contrary. All such

- 33 -

payments so made to, or upon the order of, any such holder shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Security.

SECTION 7.04. Securities Owned by Company or Controlled or Controlling Persons Disregarded for Certain Purposes. In determining whether the holders of the requisite aggregate principal amount of Securities have concurred in any demand, direction, request, notice, consent, waiver or other action under this Indenture, Securities that are owned by the Company or any other obligor on the Securities or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities shall be disregarded and deemed not to be outstanding for the purpose of any such determination, provided that for the purposes of determining whether the Trustee shall be protected in relying on any such demand, direction, request, notice, consent or waiver, only Securities that the Trustee knows are so owned shall be so disregarded. Securities so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 7.04, if the pledgee shall establish to the satisfaction of the Trustee the pledgee's right to vote such Securities and that the pledgee is not a person directly or indirectly controlling or controlled by or under direct or common control with the Company or any such obligor. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

SECTION 7.05. Record Date for Action by Securityholders. Whenever in this Indenture it is provided that holders of a specified percentage in aggregate principal amount of the Securities of a series may take any action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any action), other than any action taken at a meeting of Securityholders called pursuant to Article Eight, the Company, pursuant to a resolution of its Board of Directors, or the holders of at least ten percent in aggregate principal amount of the Securities of such series then outstanding, may request the Trustee to fix a record date for determining Securityholders entitled to notice of and to take any such action. In case the Company or the holders of Securities of such series in the amount above specified shall desire to request Securityholders of such series to take any such action and shall request the Trustee to fix a record date with respect thereto by written notice setting forth in reasonable detail the Securityholder action to be requested, the Trustee shall promptly (but in any event within five days of receipt of such request) fix a record date that shall be a Business Day not less than 15 nor more than 20 days after the date on which the Trustee receives such request. If the Trustee shall fail to fix a record date as hereinabove provided, then the Company or the holders of Securities of such series in the amount above specified may fix the same by mailing written notice thereof (the record date so fixed to be a business day not less than 15 nor more than 20 days after the date on which such written notice shall be given) to the Trustee. If a record date is fixed according to this Section 7.05, only persons shown as Securityholders of such series on the registration books for the Company at the close of business on the record date so fixed shall be entitled to take the requested action and the taking of any such action by the holders on the

- 34 -

record date of the required percentage of the aggregate principal amount of the Securities of such series shall be binding on all Securityholders of such series, provided that the taking of the requested action by the holders on the record date of the percentage in aggregate principal amount of the Securities of such series in connection with such action shall have been evidenced to the Trustee, as provided in Section 7.01, not later than 180 days after such record date.

SECTION 7.06. Instruments Executed by Securityholders Bind Future Holders. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 7.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Securities of any or all series in connection with such action, any holder of a Security of such series the serial number of which is shown by the evidence to be included in the Securities of such series the holders of which have consented to such action may, by filing written notice with the Trustee at its principal office and upon proof of holding as provided in Section 7.02, revoke such action so far as concerns such Security. Except as aforesaid any such action taken by the holder of any Security of such series and any direction, demand, request, waiver, consent, vote or other action of the holder of any Security of such series that by any provisions of this Indenture is required or permitted to be given shall be conclusive and binding upon such holder and upon all future holders and owners of such Security, and of any Security issued in lieu thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the holders of the percentage in aggregate principal amount of the Securities of such series in connection with such action shall be conclusively binding as the act of such holders upon the Company, the Trustee and the holders of the Securities of such series.

The only persons who shall be entitled to be present or to speak at any meeting of Securityholders shall be the persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel. When a

- 36 -

determination of Securityholders entitled to vote at any meeting of Securityholders has been made as provided in this Section 8.04, such determination shall apply to any adjournment thereof.

SECTION 8.05. Regulations. Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Securityholders, in regard to proof of the holding of Securities of the series with respect to which the meeting is called and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit.

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Securityholders as provided in Section 8.03, in which case the Company or the Securityholders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by a vote of the holders of a majority in principal amount of the Securities represented at the meeting and entitled to vote.

Subject to the provisions of Section 7.04, at any meeting each Securityholder or proxy entitled to vote thereat shall be entitled to one vote for each $1,000 principal amount of Securities held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Securities held by him or instruments in writing as aforesaid duly designating him as the person to vote on behalf of other Securityholders. Any meeting of Securityholders duly called pursuant to the provisions of Section 8.02 or 8.03 may be adjourned from time to time, and the meeting may be held as so adjourned without further notice.

At any meeting of Securityholders, the presence of persons who held, or who are acting as proxy for persons who held, an aggregate principal amount of Securities of the series with respect to which the meeting is called on the record date for such meeting sufficient to take action on the business for the transaction of which such meeting was called shall constitute a quorum, but, if less than a quorum is present, the persons holding or representing a majority in aggregate principal amount of the Securities of the series with respect to which the meeting is called represented at the meeting may adjourn such meeting with the same effect, for all intents and purposes, as though a quorum had been present.

SECTION 8.06. Manner of Voting at Meetings and Record to be Kept. The vote upon any resolution submitted to any meeting of Securityholders shall be by written ballots on each of which shall be subscribed the signature of the Securityholder or proxy casting such ballot

Each counterpart of such record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the counterparts shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee.

Any counterpart record so signed and verified shall be conclusive evidence of the matters therein stated and shall be the record referred to in clause (b) of Section 7.01.

SECTION 8.07. Exercise of Rights of Trustee and Securityholders Not to be Hindered or Delayed. Nothing in this Article Eight contained shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Securityholders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Securityholders under any of the provisions of this Indenture or of the Securities of any or all series.

SUPPLEMENTAL INDENTURES

SECTION 9.01. Purposes for Which Supplemental Indentures May be Entered into Without Consent of Securityholders. The Company, when authorized by a resolution of its Board of Directors, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto (which shall comply with the provisions of the Trust Indenture Act of 1939 as then in effect) for one or more of the following purposes:

- 38 -

(a) to evidence the succession of another corporation to the Company, or successive successions, and the assumption by the successor corporation of the covenants, agreements and obligations of the Company pursuant to Article Ten;

(b) to add to the covenants of the Company such further covenants, restrictions or conditions as its Board of Directors and the Trustee shall consider to be for the protection of the holders of all or any series of the Securities (and, if such covenants are to be for the benefit of less than all series of Securities stating that such covenants are expressly being included for the benefit of such series), and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions or conditions an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, however, that in respect of any such additional covenant, restriction or condition such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such Event of Default or may limit the remedies available to the Trustee upon such Event of Default or may limit the right of the holders of a majority in aggregate principal amount of the Securities of such series to waive such an Event of Default;

(c) to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture that may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make such other provisions in regard to matters or questions arising under this Indenture or any supplemental indenture as shall not adversely affect the interests of the holders of the Securities;

(d) to provide for the issuance under this Indenture of Securities, whether or not then outstanding, in coupon form (including Securities registrable as to principal only) and to provide for exchangeability of such Securities with Securities issued hereunder in fully registered form and to make all appropriate changes for such purpose;

(e) to establish the form or terms and to provide for the issuance of Securities of any series as permitted by Sections 2.01 and 2.03; and

(f) to evidence and provide for the acceptance of appointment hereunder by a successor trustee with respect to the Securities of one or more series and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee.

The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained and to accept the conveyance, transfer or assignment of any property thereunder,

- 39 -

provided that if any such supplemental indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed by the Company and the Trustee without the consent of the holders of any of the Securities at the time outstanding, notwithstanding any of the provisions of Section 9.02.

SECTION 9.02. Modification of Indenture with Consent of Holders of 66-2/3% in Principal Amount of Securities. With the consent (evidenced as provided in Section 7.01) of the holders of not less than 66-2/3% in aggregate principal amount of the Securities at the time outstanding of all Securities affected by such supplement (voting as one class) (determined as provided in
Section 7.04), or, if a record date is set with respect to such consent in accordance with Section 7.05, as of such record date, the Company, when authorized by a resolution of its Board of Directors, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto (which shall comply with the provisions of the Trust Indenture Act of 1939 as then in effect) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the Securities of each such series; provided, however, that no such supplemental indenture shall (i) extend the stated maturity of any Security, or reduce the rate or extend the time of payment of interest thereon or reduce any amount payable on redemption thereof or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereto pursuant to Section 5.01, or impair or affect the right of any Securityholder to institute suit for the payment thereof or the right of repayment if any, at the option of the Securityholder, without the consent of the holder of each Security so affected or (ii) reduce the aforesaid percentage of Securities of any series or of all series (voting as one class), as the case may be, the consent of the holders of which is required for any such supplemental indenture, without the consent of the holders of all Securities of each such series so affected.

A supplemental indenture that changes or eliminates any covenant or other provision of this Indenture that has expressly been included solely for the benefit of one or more particular series of Securities, or that modified the rights of holders of such series with respect to such covenant or provision, shall be deemed not to affect the rights under this Indenture of the holders of any other series.

Upon the request of the Company, accompanied by a copy of a resolution of its Board of Directors certified by the Secretary or an Assistant Secretary of the Company authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture, provided that if such supplemental indenture affects the

- 40 -

Trustee's own rights, duties or immunities under this Indenture or otherwise, the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

It shall not be necessary for the consent of the Securityholders under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section 9.02, the Company shall mail a notice to the Securityholders of each series affected thereby, setting forth in general terms the substance of such supplemental indenture. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

SECTION 9.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article Nine, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the holders of Securities of each series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

SECTION 9.04. Securities May Bear Notation of Changes by Supplemental Indentures. Securities of any series authenticated and delivered after the execution of any supplemental indenture affecting such series pursuant to the provisions of this Article Nine, or after any action taken at a Securityholders' meeting pursuant to Article Eight, may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture or as to any action taken at any such meeting. If the Company or the Trustee shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors of the Company, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Securities of such series then outstanding.

SECTION 9.05. Opinion of Counsel. The Trustee, subject to the provisions of Sections 6.01 and 6.02, may rely upon, and shall be entitled to receive, an Opinion of Counsel as conclusive evidence that any such supplemental indenture complies with the provisions of this Article Nine.

in the manner hereinabove provided, of the due and punctual payment of the principal or premium, if any, and interest on all of the Securities and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or observed by the Company, such successor corporation shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of Southwest Airlines Co., any or all of the Securities issuable hereunder that theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation (instead of the Company) and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities that previously shall have been signed and delivered by the officers of the Company to the Trustee of authentication, and any Securities that such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event of any such sale or conveyance and upon any such assumption, the Company or any successor corporation which shall theretofore have become such in the manner described in this Article Ten shall be discharged from all obligations and covenants under this Indenture and the Securities so assumed and may be liquidated and dissolved.

In case of any such consolidation, merger, sale or conveyance such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate.

satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

Upon the satisfaction of the conditions set forth in this Section 11.05 with respect to all the Securities of any series at the time outstanding, the terms and conditions of such series, including the terms and conditions with respect thereto set forth in this Indenture, shall no longer be binding upon, or applicable to, the Company, provided that the Company shall not be discharged from any payment obligations in respect of Securities of such series that are deemed not to be outstanding under clause (c) of the definition thereof if such obligations continue to be valid obligations in accordance with this Section by reason of any legal proceeding or any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application.

ARTICLE FOURTEEN

REDEMPTION OF SECURITIES AND SINKING FUNDS

SECTION 14.01. Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series that are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series, in either case as specified as contemplated by Section 2.03 for Securities of such series.

SECTION 14.02. Notice of Redemption; Partial Redemptions. Notice of redemption to the holders of Securities of any series to be redeemed as a whole or in part shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such holders of Securities of such series at their last addresses as they shall appear upon the Security register or registers. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the holder receives the notice. Failure to give notice by mail, or any defect in the notice to the holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series.

The notice of redemption to each such holder shall specify the principal amount of each Security of such series held by such holder to be redeemed, the date fixed for redemption, the redemption price, the place or places of payment, that payment will be made upon presentation and surrender of such Securities, that such redemption is pursuant to the mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid as specified in said notice and that on and after said date interest thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a series is to be redeemed in part only the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued.

The notice of redemption of Securities of any series to be redeemed at the option of the Company shall be given by the Company or, at the Company's request, by the Trustee for such series in the name and at the expense of the Company.

No later than the redemption date specified in the notice of redemption given as provided in this Section, the Company will deposit with the Trustee or with one or more Paying Agents (or, if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 3.04) an amount of money sufficient to redeem on the redemption date all the Securities of such series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If less than all the outstanding Securities

- 51 -

of a series are to be redeemed, the Company will deliver to the Trustee at least 70 days (or such shorter period acceptable to the Trustee) prior to the date fixed for redemption an Officers' Certificate stating the aggregate principal amount of Securities to be redeemed.

If less than all the Securities of a series are to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate and fair, Securities of such series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or any integral multiple thereof. The Trustee shall promptly notify the Company in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series selected for partial redemption, the principal amount of each such Security to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of the Securities of any series shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

SECTION 14.03. Payment of Securities Called for Redemption. If notice of redemption has been given as above provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place or places stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Securities at the redemption price, together with interest accrued to said date) interest on the Securities or portions of Securities so called for redemption shall cease to accrue and, except as provided in Sections 6.05 and 11.04, such Securities shall cease from and after the date fixed for redemption to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender of such Securities at a place of payment specified in said notice, said Securities or the specified portions thereof shall be paid and redeemed by the company at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided that any semiannual payment of interest becoming due on the date fixed for redemption shall be payable to the holders of such Securities registered as such on the relevant record date subject to the terms and provisions of Section 2.04 hereof.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by the Security.

Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to or on the order of the holder thereof, at the expense of the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

- 52 -

SECTION 14.04. Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by an authorized officer of the Company and delivered to the Trustee at least 45 (or such lesser number, not less than 30, as the Trustee may permit) days prior to the last date on which notice of redemption may be given as being owned by, and not pledged or hypothecated by, either (i) the Company or (ii) an Affiliate specifically identified in such written statement.

SECTION 14.05. Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment," and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment." The last date on which a sinking fund payment may be made in each year is herein referred to as the "sinking fund payment date."

In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Company may at its option
(i) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the mandatory sinking fund) by the Company or receive credit for Securities of such series (not previously so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Company and delivered to the Trustee for cancellation pursuant to Section 2.09, (ii) receive credit for optional sinking fund payments (not previously so credited) made pursuant to this Section, or (iii) receive credit for Securities of such series (not previously so credited) redeemed by the Company through any optional redemption provisions contained in the terms of such Securities. Securities so delivered or credited shall be received or credited by the Trustee at the sinking fund redemption price specified in such Securities.

On or before the sixtieth day (or such later day, no later than the thirtieth, as the Trustee may permit) next preceding each sinking fund payment date for any series, the Company will deliver to the Trustee a written statement (which need not contain the statements required by Section 13.05) signed by an authorized officer of the Company (i) specifying the portion of the mandatory sinking fund payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities of such series, (ii) stating that none of the securities of such series has theretofore been so credited,
(iii) stating that no defaults in the payment of interest or Events of Default with respect to such series have occurred (which have not been waived or cured) and are continuing and (iv) stating whether or not the Company intends to exercise its right to make an optional sinking fund payment with respect to such series, and, if so, specifying the amount of such optional sinking fund payment that the Company intends to pay on or before the next succeeding sinking fund payment date. Any Securities of such series to be credited and required to be delivered to the Trustee in order for the Company to be entitled to credit therefor as aforesaid that have not theretofore been delivered to the Trustee shall be delivered for cancellation pursuant to Section 2.09 to the Trustee with such written statement (or reasonably promptly

- 53 -

thereafter if acceptable to the Trustee). Such written statement shall be irrevocable and upon its receipt by the Trustee the Company shall become unconditionally obligated to make all the cash payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Company, on or before any such sixtieth day (or such later day as the Trustee may have permitted), to deliver such written statement and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable election of the Company (i) that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof and
(ii) that the Company will make no optional sinking fund payment with respect to such series as provided in this Section.

If the sinking fund payment or payments (mandatory or optional or both) made in cash plus any unused balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or a lesser sum if the Company shall so request) with respect to the Securities of any particular series, such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If such amount shall be $50,000 or less and the Company makes no such request then it shall be carried over until a sum in excess of $50,000 is available. The Trustee shall select, in the manner provided in Section 14.02, for redemption on such sinking fund payment date a sufficient principal amount of Securities of such series to absorb said cash, as nearly as may be, and shall (if requested in writing by the Company) inform the Company or an entity known by the Trustee to be an Affiliate, as shown by the Security register or registers, and not known to the Trustee to have been pledged or hypothecated by the Company or any such entity or (ii) identified in a written statement delivered to the Trustee pursuant to Section 14.04 as being owned by, and not pledged or hypothecated by, the Company or an Affiliate shall be excluded from Securities of such series eligible for selection for redemption. The Trustee, in the name and at the expense of the Company (or the Company, if it shall so request the Trustee in writing) shall cause notice of redemption of the Securities of such series to be given in substantially the manner provided in Section 14.02 (and with the effect provided in Section 14.03) for the redemption of Securities of such series in part at the option of the Company. The amount of any sinking fund payments not so applied or allocated to the redemption of Securities of such series shall be added to the next cash sinking fund payment and, together with such payment, shall be applied in accordance with the provisions of this
Section 13.04. Any and all sinking fund moneys held on the stated maturity date of the Securities of any particular series (or earlier, if such maturity is accelerated), that are not held for the payment or redemption of particular Securities of such series shall be applied, together with other moneys if necessary, sufficient for the purpose, to the payment of the principal of, and interest on, the Securities of such series at maturity.

The Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking fund moneys or mail any notice of redemption of Securities for such series by operation of the sinking funds during the continuance of a default in payment of interest on such Securities

- 54 -

or of any Event of Default except that, where the mailing of notice of redemption of any securities shall theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Company a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance of such default or Event of Default, be deemed to have been collected under Article Five and held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Article Five or the default cured on or before the sixtieth day preceding the sinking fund payment date in any year, such moneys shall thereafter be applied on the next succeeding sinking fund payment date in accordance with this Section to the redemption of such Securities.

U.S. Trust Company of Texas, N.A., the party of the second part, hereby accepts the trust in this Indenture declared and provided, upon the terms and conditions hereinabove set forth.

PART A

BOEING WARRANTY

1. Warranties.

Subject to the exceptions set forth in paragraph 2, Boeing warrants that, at the time of delivery, each Aircraft, including all installed systems, accessories, equipment and parts, will:

1.1 conform to the Detail Specification, as it may be changed pursuant to this Agreement, except such portions stated to be estimates, approximations, design objectives, or design criteria, or described as not guaranteed;

1.2 be free from defects in material and workmanship, including process of manufacture; and

1.3 be free from defects in design, including selection of
(i) materials and (ii) process of manufacture, in view of the state of the art at the time of design.

For purposes of this Boeing Warranty, nonconformance with the Detail Specification, defects in material or workmanship and defects in design may hereinafter be called "defects" or a "defect", and the term "system", "accessory", "equipment" or "part" may hereinafter be called "item" or "items."

2. Exceptions.

The warranties above will not apply to BFE. The warranty above covering material and workmanship and the warranty above covering design will not apply to Engines or to any other item purchased by Boeing but not manufactured to Boeing's detailed design. However, any defect in the Boeing workmanship installing such BFE, Engines or other items in an Aircraft will, including any failure by Boeing to conform to the installation instructions of the manufacturer of such items that invalidates any applicable warranty from such manufacturer, constitute a defect in workmanship and be covered by the warranty set forth in paragraph 1.

3. Survival of Warranties.

Neither the warranty of conformance to the Detail Specification applicable to Engines and other items purchased by Boeing but not manufactured to Boeing's detailed design, nor any Performance Guarantees, will survive delivery of the Aircraft. The remaining warranties

A-1

set forth herein will survive delivery of the Aircraft, subject to the limitations and conditions set forth herein.

4. Warranty Periods and Claims.

4.1 The warranty periods are:

4.1.1 As to a defect in conformance to the Detail Specification, 48 months after delivery of such Aircraft, and

4.1.2 As to a defect in material, workmanship or design in any item, 48 months after delivery of each Aircraft in which such item was initially installed.

4.2 Boeing must receive the warranty claim in writing at the earliest practicable time after the defect becomes apparent to Buyer but in no event later than 90 days after expiration of the applicable warranty period.

4.3 Such warranty claim must include the data set forth below and, if requested by Boeing, reasonable evidence that the claimed defect did not result from any act or omission of Buyer.

4.3.1 Identity of the item or Aircraft involved, including Boeing part number, serial number if applicable, nomenclature and the quantity claimed to be defective;

4.3.2 Identity of the Aircraft on which the claimed item was installed as original equipment;

                        4.3.3         Date the claimed defect became apparent to
Buyer; and

                        4.3.4         Description of the claimed defect and

circumstances, including Boeing service bulletin or Boeing service letter number if claim involves a service bulletin or letter.

4.4 Upon completion of Boeing's warranty claim investigation, including examination of any item or Aircraft returned to Boeing, Boeing will provide a written disposition of its warranty claim findings to Buyer. In the event Boeing must reject Buyer's warranty claim, Boeing will provide reasonable substantiation of such rejection in its disposition.

A-2

5. Remedies.

Buyer's remedies under this Boeing Warranty are as follows:

5.1 As to a defect in conformance to the Detail Specification, the correction at Boeing's expense of such defect; provided, however, that Boeing will not be obligated to correct any defect that Boeing and Buyer agree has no material adverse effect on the maintenance, use or operation of the Aircraft. The warranty period for the corrected item will be the unexpired warranty period for the defective item.

5.2 As to a defect in material or workmanship, (i) the repair at Boeing's expense of such defect or, (ii) at Boeing's option, the replacement of such item with a similar item free from defect or the issuance of a credit memorandum to Buyer for a spare part previously purchased from Boeing as the replacement for such defective item. The warranty period for either correction will be the unexpired warranty period for the defective item.

5.3 As to a defect in design, the correction at Boeing's expense of such defect. The warranty period for such correction is 18 months from receipt by Buyer of corrective material or the end of the original design warranty period for the defective item, whichever is later.

5.4 Boeing will reimburse Buyer at the Warranty Labor Rate for the direct labor hours required for removal from the Aircraft of a defective item and the reinstallation in the Aircraft of the corrected item.

6. Returned Items.

Unless otherwise provided in this Agreement, the Aircraft or item claimed to be defective must be returned to Boeing as soon as practicable. Buyer may also provide specific technical repair or correction instructions with such return. The absence of such instructions will evidence Buyer's authorization for Boeing to proceed using Boeing information and data. The following criteria will apply with respect to return of Aircraft or items to Boeing:

6.1 As to Aircraft:

6.1.1 An Aircraft may be returned only if

6.1.1.1 substantially all the work to be performed by Boeing is covered by this Boeing Warranty and

6.1.1.2 Buyer does not have the capability to perform, nor is it practical for Boeing

A-3

personnel to perform, the warranty work away from Boeing's facilities.

6.1.2 All warranty work will be performed at Boeing's expense, with reasonable efforts to minimize Aircraft out-of-service time. In addition, Boeing will reimburse Buyer for the cost of fuel, oil and landing fees incurred in ferrying the Aircraft to Boeing's facilities and in ferrying the Aircraft back to Buyer's facilities. Buyer will use its best efforts to minimize the length of both ferry flights.

6.1.3 Any nonwarranty work performed by Boeing will be paid for by Buyer at Boeing's then-standard rates and shall in no event exceed the rates charged other commercial carriers of Boeing during substantially the same time period.

6.1.4 A separate agreement containing the above provisions and their mutually agreeable terms and conditions based on Boeing's then-standard form will be entered into to cover the return of and work on such Aircraft.

6.2 As to any system, accessory, equipment or part:

6.2.1 All warranty work will be performed at Boeing's expense, with reasonable efforts to minimize item out-of-service time for items returned.

6.2.2 Boeing's turnaround-time objectives for repair or replacement are: 10 working days for avionic and electronic items and 30 working days for other items when corrected at Boeing's facilities, or 40 working days when corrected at the facilities of a Boeing subcontractor. Turnaround time starts the date Boeing receives the returned item, together with Buyer's warranty claim describing the work, and ends the date of shipment by Boeing of such item. If a turnaround-time objective is not achieved and a resultant critical parts shortage is experienced by Buyer, and Buyer has procured spare parts for such item substantially in accordance with the Boeing Recommended Spare Parts List, Boeing will, upon request from Buyer, either:

                                      6.2.2.1  expedite repair or replacement of
the item or

                                      6.2.2.2  provide a similar item on a

no-charge loan or no-charge lease basis until the repaired or replaced item is provided to Buyer.

6.2.3 The freight charge for shipment to Boeing of any item will be paid by Buyer; however, Boeing

A-4

will reimburse Buyer for such charge for any item determined to be defective under this Boeing Warranty. The freight charge for the return shipment to Buyer of any such defective item which has been repaired, replaced or corrected pursuant to this Boeing Warranty will be paid by Boeing.

6.3 Title to and risk of loss of any Aircraft or item returned to Boeing will at all times remain with Buyer and/or any other owner of such Aircraft or item, except that at the time Boeing ships a replacement item to Buyer, title to and risk of loss (i) for the returned item will pass to Boeing and (ii) for the replacement item will pass to Buyer. While Boeing has care, custody and control of an Aircraft or item, Boeing will have only such liabilities as a bailee for mutual benefit would have, but will not be liable for loss of use.

7. Nonrepairable Items.

Buyer may scrap any defective nonrepairable item having a then-current Boeing spare part selling price of $2,000 or less and make a claim for a replacement item. For a defective nonrepairable item having a then-current Boeing spare part selling price greater than $2,000, an authorized Boeing representative must confirm the nonrepairability of any such item. Buyer's claim for an item with a spare part selling price exceeding $2,000 must include such confirmation.

8. Reimbursement for Certain Inspection Labor Costs.

8.1 In addition to the remedies set forth in this Boeing Warranty, Boeing will reimburse Buyer at the Warranty Labor Rate for the direct labor hours expended by Buyer in performing inspections of the Aircraft to determine whether or not a covered defect exists in any system, accessory, equipment or part manufactured to Boeing's detailed design, provided that:

8.1.1 such inspections are recommended by a Boeing service bulletin or service letter issued by Boeing within 48 months after delivery of such Aircraft, and

8.1.2 such reimbursement will not apply to any inspections performed as an alternative to accomplishing corrective action when such corrective action is available to Buyer at the time such inspections are performed.

9. Wear and Tear.

Normal wear and tear and the need for regular maintenance and overhaul will not constitute a defect.

A-5

10. Disclaimer and Release; Exclusion of Liabilities.

This Part A and the rights and remedies of Buyer and obligations of Boeing herein are subject to the Disclaimer and Release and Exclusion of Consequential and Other Damages provisions of Article 12 of this Agreement.

11. Buyer's Indemnification of Boeing.

The provisions of Part E, "Buyer's Indemnification of Boeing and Insurance" of Exhibit C, will apply to all warranty work performed by Boeing hereunder in accordance with Buyer's specific technical repair or correction instructions, to the extent any legal liability of Boeing is based upon the content of such instructions.

7. Termination of Option to Purchase.

Either Boeing or Buyer may terminate the option to purchase an Option Aircraft if any of the following events are not accomplished by the respective dates contemplated in this letter agreement, or in the Agreement, as the case may be:

(i) termination of the purchase of the Aircraft under the Agreement for any reason;

(ii) payment by Buyer of the Deposit with respect to an Option Aircraft pursuant to paragraph 4.1 herein;

(iii) exercise of an option to purchase an Option Aircraft pursuant to the terms hereof. Any termination of an option to purchase by Boeing which is based on the termination of the purchase of Aircraft under the Agreement will be on a one-for-one basis, for each Aircraft so terminated.

Any cancellation of an option to purchase which is based on failure to make the required Deposit or to exercise the option to purchase shall only apply to the Option Aircraft so canceled.

Termination of an option to purchase provided by this letter agreement will be caused by either party giving written notice to the other within 10 days after the applicable date. Upon receipt of such notice, all rights and obligations of the parties with respect to an Option Aircraft for which the option to purchase has been terminate will thereupon terminate.

If termination is result of a revision of an option exercise date by Boeing pursuant to paragraph 5.2, Boeing will promptly refund to Buyer, without interest, any payments received from Buyer, including the Deposit, with respect to the Option Aircraft for which the option is terminated. If termination is for any other reason, Boeing will promptly refund to Buyer, without interest, any payments received from Buyer with respect to the affected Option Aircraft, except the Deposit, which Buyer may apply to any model Boeing aircraft purchased by Buyer from Boeing at a future date.

PRICE ADJUSTMENT DUE TO
ECONOMIC FLUCTUATIONS
AIRCRAFT PRICE ADJUSTMENT
(July 1992 Base Price)

1. Formula.

The Aircraft Price Adjustment will be determined at the time of Aircraft delivery in accordance with the following formula:

Pa = (P)(L + M - 1)

Where:

Pa = Aircraft Price Adjustment.

L =      .65 x  ECI
               116.2

M =      .35 x  ICI
               115.9

P = Aircraft Basic Price (as set forth in Article 3.2 of this Agreement).

ECI = A value using the "Employment Cost Index for workers in aerospace manufacturing" (aircraft manufacturing, standard industrial classification code 3721, compensation, base month and year June 1989 = 100), as released by the Bureau of Labor Statistics, U.S. Department of Labor on a quarterly basis for the months of March, June, September and December, calculated as follows: A three-month arithmetic average value
(expressed as a decimal and rounded to the nearest tenth)
will be determined using the months set forth in the table below for the applicable Aircraft, with the released Employment Cost Index value described above for the month of March also being used for the months of January and February; the value for June also used for April and May; the value for September also used for July and August; and the value for December also used for October and November.


Attachment B to
6-1162-RLL-933R1

Page 2

ICI = The three-month arithmetic average of the released monthly values for the Industrial Commodities Index as set forth in the "Producer Prices and Price Index" (Base Year 1982 = 100) as released by the Bureau of Labor Statistics, U.S. Department of Labor values (expressed as a decimal and rounded to the nearest tenth) for the months set forth in the table below for the applicable Aircraft.

In determining the value of L, the ratio of ECI divided by 116.2 will be expressed as a decimal rounded to the nearest ten-thousandth and then multiplied by .65 with the resulting value also expressed as a decimal and rounded to the nearest ten-thousandth.

In determining the value of M, the ratio of ICI divided by 115.9 will be expressed as a decimal rounded to the nearest ten-thousandth and then multiplied by .35 with the resulting value also expressed as a decimal and rounded to the nearest ten-thousandth.

2. If at the time of delivery of an Aircraft Boeing is unable to determine the Aircraft Price Adjustment because the applicable values to be used to determine the ECI and ICI have not been released by the Bureau of Labor Statistics, then:

2.1 The Aircraft Price Adjustment, to be used at the time of delivery of each of the Aircraft, will be determined by utilizing the escalation provisions set forth above. The values released by the Bureau of Labor Statistics and available to Boeing 30 days prior to scheduled Aircraft delivery will be used to determine the ECI and ICI values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Aircraft Price Adjustment. If no values have been released for an applicable month, the provisions set forth in Paragraph 2.2 below will apply. If prior to delivery of an Aircraft the U.S. Department of Labor changes the base year for determination of the ECI or ICI values as defined above, such rebased values will be incorporated in the Aircraft Price Adjustment calculation. The payment by Buyer to Boeing of the amount of the Purchase Price for such Aircraft, as determined at the time of Aircraft delivery, will be deemed to be the payment for such Aircraft required at the delivery thereof.

2.2 If prior to delivery of an Aircraft the U.S. Department of Labor substantially revises the methodology used for the determination of the values to be used to determine the ECI and ICI values (in contrast to benchmark adjustments or other corrections of previously released values), or for any reason has not released values needed to determine the applicable Aircraft Price Adjustment, the parties will, prior to delivery of any such Aircraft, select a substitute for such values from data published by the Bureau of Labor Statistics or other similar data reported by non-governmental United States organizations, such substitute to lead in application to the same adjustment result, insofar as possible, as would have been achieved by continuing the use of the original values as they may have fluctuated during the applicable time period. Appropriate revision of the formula will be made as required to reflect any substitute values. However, if within 24 months from delivery of the Aircraft the Bureau of Labor Statistics should resume releasing values for the months needed to determine the Aircraft Price Adjustment, such values will be used to determine any increase or decrease in the Aircraft


Attachment B to
6-1162-RLL-933R1

Page 4

Price Adjustment for the Aircraft from that determined at the time of delivery of such Aircraft.

2.3 In the event escalation provisions are made non-enforceable or otherwise rendered null and void by any agency of the United States Government, the parties agree, to the extent they may lawfully do so, to equitably adjust the Purchase Price of any affected Aircraft to reflect an allowance for increases or decreases in labor compensation and material costs occurring since February, 1992, which is consistent with the applicable provisions of paragraph 1 of this Exhibit D.

3. For the calculations herein, the values released by the Bureau of Labor Statistics and available to Boeing 30 days prior to scheduled Aircraft delivery will be used to determine the ECI and ICI values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Aircraft Price Adjustment.

Note: Any rounding of a number, as required under this Exhibit D with respect to escalation of the airframe price, will be accomplished as follows: if the first digit of the portion to be dropped from the number to be rounded is five or greater, the preceding digit will be raised to the next higher number.
