S-3 RISK FACTORS You should carefully review the information included elsewhere and incorporated by reference in this prospectus supplement and the accompanying prospectus and should particularly consider the following matters. This prospectus supplement and the accompanying prospectus include or incorporate by reference "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which represent our expectations or beliefs concerning future events. When used in this prospectus supplement and the accompanying prospectus and the incorporated documents, the words "expects," "plans," "anticipates" and similar expressions are intended to identify forward-looking statements. All forward-looking statements in this prospectus supplement are based upon information available to us on the date of this prospectus supplement. We undertake no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future events or otherwise. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or our expectations. Additional information concerning these and other factors is contained in our SEC filings, including but not limited to our Forms 10-K, 10-Q and 8-K. Absence of Certain Covenants. The terms of the notes do not limit our ability to incur additional indebtedness, to mortgage or pledge any of our assets or to pay dividends or make other distributions in respect of, or redeem or repurchase, our common stock. In addition, the notes do not contain provisions that would give holders of the notes the right to require us to repurchase their notes in the event of a change of control or a decline in the credit rating of our debt securities resulting from a takeover, recapitalization or similar restructuring or any other reason. Absence of Public Market. The notes are new securities for which there presently is no market. Although the underwriters have advised us that they currently intend to make a market in the notes, they are not obligated to do so and any such market making may be discontinued at any time without notice in the sole discretion of the underwriters. If an active public market does not develop, the market price and liquidity of the notes may be adversely affected. If a trading market develops for the notes, the future trading prices thereof will depend on many factors including, among other things, our results of operations, prevailing interest rates, the market for securities with similar terms and the market for securities of other companies in similar businesses. We do not intend to apply for a listing of the notes on any securities exchange or for their quotation through any automated dealer quotation system. THE COMPANY Southwest Airlines Co. is a major domestic airline that provides primarily shorthaul, high-frequency, point-to-point, low-fare service. We were incorporated in Texas in 1967 and commenced Customer Service on June 18, 1971 with three Boeing 737 aircraft serving three Texas cities -- Dallas, Houston, and San Antonio. At year-end 2001, we operated 355 Boeing 737 aircraft and provided service to 59 airports in 58 cities in 30 states throughout the United States. We commenced service to West Palm Beach, Florida in January 2001 and to Norfolk, Virginia in October 2001. Based on data for second quarter 2001 (the latest available data), we are the 4th largest carrier in the United States based on domestic passengers boarded and the second largest based on scheduled domestic departures. Excluding consideration of any remaining federal grant proceeds, it is difficult to predict whether or not we will be profitable in first quarter 2002 due to uncertain economic conditions and the difficult airline industry revenue environment. Our business is also somewhat seasonal, and quarterly operating income and, to a lesser extent, revenues tend to be lower in the first quarter (January 1-March 31). Additional information about us is included in our reports and other documents incorporated by reference in this prospectus supplement and the accompanying prospectus. See "Where You Can Find More Information" in the accompanying prospectus. S-4 USE OF PROCEEDS We expect our net proceeds from the offering of the notes to be approximately $380.1 million. We will use the net proceeds for general corporate purposes, including, among other possible uses, repayment of a portion of the $475 million of borrowings outstanding under our bank credit facility and accrued interest thereon. The bank credit facility was drawn down in mid-September 2001 for general corporate purposes and bears interest at six-month LIBOR (as defined in the bank credit facility) plus a margin, which is currently 0.170%. The bank credit facility matures in May 2002, and any borrowings under the facility may be repaid at any time. S-5 CAPITALIZATION The following table sets forth our consolidated capitalization at December 31, 2001 and as adjusted for the issuance and sale of the notes.

S-6 RATIOS OF EARNINGS TO FIXED CHARGES The following table sets forth our historical ratios of earnings to fixed charges for the years indicated:
YEAR ENDED DECEMBER 31, -------------------------------- 1997 1998 1999 2000 2001 ---- ---- ---- ---- ---- 3.50 4.58 5.01 5.97 4.94
Earnings represent: - Income before income taxes, excluding the cumulative effect of accounting changes; plus - Fixed charges, excluding capitalized interest. Fixed charges include: - Interest, whether expensed or capitalized; and - A portion of rental expense. Our management believes this is representative of the interest factor in those periods. DESCRIPTION OF NOTES We will issue the notes under the indenture referred to in the accompanying prospectus between us and U.S. Trust Company of Texas, N.A., as trustee. The following description, together with the description in the accompanying prospectus under the caption "Description of Debt Securities Southwest May Offer," is a summary of the material provisions of the notes and the indenture. It does not restate the indenture in its entirety. We urge you to read the indenture because it, and not this description, defines your rights as holders of the notes. We have filed a form of the indenture as an exhibit to our registration statement, which includes the accompanying prospectus. This description of the notes supplements, and, to the extent it is inconsistent, replaces, the description of the general provisions of the notes and the indenture in the accompanying prospectus. The notes are a series of our debt securities as that term is used in the accompanying prospectus. With certain exceptions and pursuant to certain requirements set forth in the indenture, we may discharge our obligations under the indenture with respect to the notes as described under the caption "Description of Debt Securities Southwest May Offer -- Defeasance" in the accompanying prospectus. PRINCIPAL, MATURITY AND INTEREST The notes will mature on March 1, 2012. Although we are offering $385 million principal amount of the notes, we may issue and sell additional principal amounts of the notes in the future without the consent of the holders of the notes. Any additional notes, together with these notes, constitute a single series of notes under the indenture, and are designated as the 6 1/2% Notes Due 2012. Interest on the notes will accrue at the rate of 6 1/2% per year and will be payable semiannually on each March 1 and September 1, commencing September 1, 2002. We will make each interest payment to the person in whose name the notes are registered at the close of business on the relevant February 15 and August 15 preceding the applicable interest payment date. Interest on the notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. If any interest payment date, redemption date or maturity date falls on a day that is not a business day, the payment will be made on the next business day with the same force and effect as if made on the relevant interest payment date, redemption date or maturity date, and, unless we default on the payment, no interest will accrue for the period from and after the interest payment date, redemption date or maturity date. S-7 REDEMPTION We will have the right to redeem the notes, in whole or in part at any time, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on such notes (exclusive of interest accrued to the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to such redemption date. "Comparable Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes. "Comparable Treasury Price" means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. "Quotation Agent" means one of the Reference Treasury Dealers appointed by the trustee after consultation with us. "Reference Treasury Dealer" means each of Merrill Lynch Government Securities Inc. and four other Reference Treasury Dealers determined by us and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a "Primary Treasury Dealer"), we will substitute therefor another Primary Treasury Dealer. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding such redemption date. "Treasury Rate" means, with respect to any redemption date, the rate per year equal to the semiannual equivalent yield to maturity or interpolated yield (on a day count basis) of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate will be calculated on the third business day preceding the redemption date. There will be no sinking fund for the notes. REDEMPTION PROCEDURES We will provide not less than 30 nor more than 60 days' notice mailed to each registered holder of the notes to be redeemed. If the redemption notice is given and funds deposited as required, then interest will cease to accrue on and after the redemption date on the notes or portions of such notes called for redemption. If fewer than all of the notes are to be redeemed at any time, selection of notes for redemption will be made by the trustee in compliance with the requirements of the principal national securities exchange, if any, on which the notes are listed or, if the notes are not listed on a national securities exchange, on a pro rata basis, provided, however, that the notes will be redeemed only in the amount of $1,000 or integral multiples thereof. S-8 RANKING The notes will be our direct, unsecured and unsubordinated obligations. The notes will rank pari passu, or equal in right of payment, with all of our other unsubordinated indebtedness and senior in right of payment to all of our future subordinated debt. The indenture contains no restrictions on the amount of additional indebtedness that we may issue under it. DENOMINATIONS The notes will be issuable in denominations of $1,000 and integral multiples of $1,000. BOOK-ENTRY, DELIVERY AND FORM The notes will be issued initially in the form of a global security registered in the name of The Depository Trust Company ("DTC") or its nominee, as described under the caption "Description of Debt Securities Southwest May Offer -- Global Securities" in the accompanying prospectus. DTC has advised us and the underwriters of the notes as follows: DTC is a limited-purpose trust company organized under the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC's participants include securities brokers and dealers (including the underwriters of the notes), banks, trust companies, clearing corporations and certain other organizations, some of which (and/or their representatives) own interests in DTC. Access to DTC's book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain custodial relationship with a participant, either directly or indirectly. Settlement for the notes will be made in same-day funds. We will make all payments of principal and interest on any notes held by DTC in immediately available funds. To the extent any notes are held by DTC, DTC will require secondary trading activity in the notes to be settled in immediately available funds. TRUSTEE The trustee, U.S. Trust Company of Texas, N.A., has informed us that it expects The Bank of New York to succeed to its corporate trust business on or about March 11, 2002. If that transaction occurs, then The Bank of New York will be the successor trustee under the indenture. GOVERNING LAW The indenture provides that it and the notes will be governed by, and construed in accordance with, the laws of the State of Texas. S-9 UNDERWRITING We intend to offer the notes through the underwriters. Merrill Lynch, Pierce, Fenner & Smith Incorporated is acting as representative for the underwriters named below. Subject to the terms and conditions contained in an underwriting agreement between us and the underwriters, we have agreed to sell to the underwriters and the underwriters severally have agreed to purchase from us, the principal amount of the notes listed opposite their names below.
PRINCIPAL AMOUNT UNDERWRITER --------- ----------- Merrill Lynch, Pierce, Fenner & Smith Incorporated................................... $231,000,000 Banc One Capital Markets, Inc. ............................. 38,500,000 First Union Securities, Inc. ............................... 38,500,000 Tokyo-Mitsubishi International plc.......................... 38,500,000 Wells Fargo Brokerage Services, LLC......................... 38,500,000 ------------ Total.......................................... $385,000,000 ============
The underwriters have agreed to purchase all of the notes sold pursuant to the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities. The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. The underwriters have advised us that they propose initially to offer the notes to the public at the public offering price on the cover page of this prospectus supplement, and to dealers at that price less a concession not in excess of .4% of the principal amount of the notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of .25% of the principal amount of the notes to other dealers. After the initial public offering, the public offering price, concession and discount may be changed. The expenses of the offering, excluding the underwriting discount, are estimated to be $200,000 and are payable by us. The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for quotation of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. Banc One Capital Markets, Inc., First Union Securities, Inc., Tokyo-Mitsubishi International plc and Wells Fargo Brokerage Services, LLC are underwriters in this offering and their respective affiliates, Bank One, Texas, N.A., Wachovia Bank of Georgia, N.A., Mitsubishi Trust and Banking Corporation, New York Branch, Bank of Tokyo-Mitsubishi, LTD., Houston Agency, and Wells Fargo Bank, Texas participate in our bank credit facility and will receive a portion of the amounts, if any, which may be S-10 repaid under such facility with net proceeds of the offering. See "Use of Proceeds." Because more than 10% of the net proceeds of the offering may be paid to affiliates of the underwriters, the offering is being made pursuant to Rule 2710(c)(8) of the Conduct Rules of the National Association of Securities Dealers, Inc. Subject to the terms and conditions of the underwriting agreement we have agreed to sell to First Union Securities, Inc., ("First Union"), an indirect, wholly-owned subsidiary of Wachovia Corporation, and First Union has agreed to purchase notes from us. Wachovia Corporation conducts its investment banking, institutional, and capital markets businesses through its various bank, broker-dealer and nonbank subsidiaries (including First Union) under the trade name of Wachovia Securities. Any references to Wachovia Securities in this prospectus supplement, however, do not include Wachovia Securities, Inc., member NASD/SIPC and a separate broker-dealer subsidiary of Wachovia Corporation and sister affiliate of First Union which may or may not be participating as a selling dealer in the distribution of the notes. In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the notes. Such transactions consist of bids or purchases to peg, fix or maintain the price of the notes. If the underwriters create a short position in the notes in connection with the offering, i.e., if they sell more notes than are on the cover page of this prospectus, the underwriters may reduce that short position by purchasing notes in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us. They have received customary fees and commissions for these transactions. VALIDITY OF NOTES The validity of the notes will be passed upon for us by Vinson & Elkins L.L.P., Houston, Texas, and for the underwriters by Milbank, Tweed, Hadley & McCloy LLP, New York, New York. Members of the firm of Vinson & Elkins L.L.P. having responsibility for our legal matters beneficially own approximately 27,500 shares of our common stock. EXPERTS Ernst & Young LLP, independent auditors, have audited our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2001, as set forth in their report, which is incorporated by reference in this prospectus supplement.

SIX MONTHS ENDED JUNE 30, YEAR ENDED DECEMBER 31, -------------- -------------------------------------------- 2000 2001 1996 1997 1998 1999 2000 ---- ---- ---- ---- ---- ---- ---- 5.56 5.77 2.73 3.50 4.58 5.01 5.97

DESCRIPTION OF DEBT SECURITIES SOUTHWEST MAY OFFER As required by federal law for all bonds and notes of companies that are publicly offered, the debt securities are governed by a document called the indenture. The indenture is a contract, dated as of February 25, 1997, between Southwest and U.S. Trust Company of Texas, N.A., which acts as trustee. The trustee has two main roles. First, the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described under "Remedies If an Event of Default Occurs." Second, the trustee performs administrative duties for us, such as sending you interest payments, transferring your debt securities to a new buyer if you sell and sending you notices. The indenture and its associated documents contain the full legal text of the matters described in this section. The indenture and the debt securities are governed by Texas law. A copy of the indenture may be obtained from Southwest as described below under "Where You Can Find More Information." 1 Southwest may issue as many distinct series of debt securities under the indenture as it wishes. This section summarizes the material terms of the debt securities that are common to all series, although the prospectus supplement which describes the terms of each series of debt securities may also describe differences with the material terms summarized here. Because this section is a summary, it does not describe every aspect of the debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of certain terms used in the indenture. In this summary, Southwest describes the meaning for only the more important terms. You must look to the indenture for the most complete description of what Southwest describes in summary form in this prospectus. This summary also is subject to and qualified by reference to the description of the particular terms of your series described in the prospectus supplement. Those terms may vary from the terms described in this prospectus. The prospectus supplement relating to each series of debt securities will be attached to the front of this prospectus. There may also be a further prospectus supplement, known as a pricing supplement, which contains the precise terms of debt securities you are offered. Southwest may issue the debt securities as original issue discount securities, which will be offered and sold at a substantial discount below their stated principal amount. The prospectus supplement relating to the original issue discount securities will describe federal income tax consequences and other special considerations applicable to them. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities. In addition, the specific financial, legal and other terms particular to a series of debt securities are described in the prospectus supplement and any pricing supplement relating to the series. The prospectus supplement relating to a series of debt securities will describe the following terms of the series: - the title of the series of debt securities; - any limit on the aggregate principal amount of the series of debt securities; - the person to whom interest on a debt security is payable, if other than the holder on the regular record date; - the date or dates on which the series of debt securities will mature; - the rate or rates, which may be fixed or variable, per annum at which the series of debt securities will bear interest, if any, and the date or dates from which that interest, if any, will accrue; - the place or places where the principal of (and premium, if any) and interest on the debt securities are payable; - the dates on which interest, if any, on the series of debt securities will be payable and the regular record dates for the interest payment dates; - any mandatory or optional sinking funds or similar provisions or provisions for redemption at the option of the issuer; - the date, if any, after which and the price or prices at which the series of debt securities may, in accordance with any optional or mandatory redemption provisions, be redeemed and the other detailed terms and provisions of those optional or mandatory redemption provisions, if any; - if other than denominations of $1,000 and any of its integral multiples, the denominations in which the series of debt securities will be issuable; - the applicability of the provisions described under "Defeasance;" - if the series of debt securities will be issuable only in the form of a global security, the depository or its nominee with respect to the series of debt securities and the circumstances under which the 2 global security may be registered for transfer or exchange in the name of a person other than the depositary or the nominee; and - any other special feature of the series of debt securities. LEGAL OWNERSHIP Street Name and other Indirect Holders. Investors who hold debt securities in accounts at banks or brokers will generally not be recognized by us as legal holders of debt securities. This is called holding in street name. Instead, Southwest would recognize only the bank or broker, or the financial institution the bank or broker uses to hold its debt securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to. If you hold debt securities in street name, you should check with your own institution to find out: - how it handles securities payments and notices; - whether it imposes fees or charges; - how it would handle voting if required; - whether and how you can instruct it to send you debt securities registered in your own name so that you can be a direct holder as described below; and - how it would pursue rights under the debt securities if there were a default or other event triggering the need for holders to act to protect their interests. Direct Holders. Our obligations, as well as the obligations of the trustee and those of any third parties employed by Southwest or the trustee, run only to persons who are registered as holders of debt securities. As noted above, Southwest does not have obligations to you if you hold debt securities in street name or other indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities as described below. For example, once we make payment to the registered holder, we have no further responsibility for the payment, even if that holder is legally required to pass the payment along to you as a street name customer but does not do so. GLOBAL SECURITIES What is a Global Security? A global security is a special type of indirectly held security, as described above under "Street Name and Other Indirect Holders." If Southwest chooses to issue debt securities in the form of global securities, the ultimate beneficial owners can only be indirect holders. Southwest does this by requiring that the global security be registered in the name of a financial institution it selects and by requiring that the debt securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below occur. The financial institution that acts as the sole direct holder of the global security is called the depositary. Any person wishing to own a debt security must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the depositary. The prospectus supplement indicates whether your series of securities will be issued only in the form of global securities. Special Investor Considerations for Global Securities. As an indirect holder, an investor's rights relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize this type of investor as a holder of debt securities and instead deal only with the depositary that holds the global security. 3 If you are an investor, you should be aware that if debt securities are issued only in the form of global securities: - You cannot get debt securities registered in your own name. - You cannot receive physical certificates for your interest in the debt securities. - You will be a street name holder and must look to your own bank or broker for payments on the debt securities and protection of your legal rights relating to the debt securities. See "Legal Ownership -- Street Name and Other Indirect Holders." - You may not be able to sell interests in the debt securities to some insurance companies and other institutions that are required by law to own their securities in the form of physical certificates. - The depositary's policies will govern payments, transfers, exchange and other matters relating to your interest in the global security. Southwest and the trustee have no responsibility for any aspect of the depositary's actions or for its records of ownership interest in the global security. Southwest and the trustee also do not supervise the depositary in any way. Special Situations when Global Security will be Terminated. In a few special situations described in the next paragraph, the global security will terminate and interests in it will be exchanged for physical certificates representing debt securities. After that exchange, the choice of whether to hold debt securities directly or in street name will be up to you. You must consult your own bank or broker to find out how to have your interests in debt securities transferred to our own name, so that you will be a direct holder. The rights of street name investors and direct holders in the debt securities have been previously described in the subsections entitled "Street Name and Other Indirect Holders" and "Direct Holders." The special situations for termination of a global security are: - When the depositary notifies Southwest that it is unwilling, unable or no longer qualified to continue as depositary and a successor depositary is not appointed by Southwest within 90 days. - When Southwest notifies the trustee that it wishes to terminate the global security. - When an event of default on the securities has occurred and has not been cured, disregarding for this purpose any requirement of notice or that the default exists for a specified period of time. (Default is discussed later under "Events of Default") The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of debt securities covered by the prospectus supplement. When a global security terminates, the depositary (and not Southwest or the trustee) is responsible for deciding the names of the institutions that will be the initial direct holders. IN THE REMAINDER OF THIS DESCRIPTION "YOU" MEANS DIRECT HOLDERS AND NOT STREET NAME OR OTHER INDIRECT HOLDERS OF DEBT SECURITIES. INDIRECT HOLDERS SHOULD READ THE PREVIOUS SUBSECTION ENTITLED "STREET NAME AND OTHER INDIRECT HOLDERS." OVERVIEW OF REMAINDER OF THIS DESCRIPTION The remainder of this description summarizes: - ADDITIONAL MECHANICS relevant to the debt securities under normal circumstances, such as how you transfer ownership and where Southwest makes payments; - Your rights in several SPECIAL SITUATIONS, such as if Southwest merges with another company, or if Southwest wants to change a term of the debt securities; - A DEFEASANCE clause, which may allow for Southwest to be completely released from its payment and other obligations on the debt securities; and 4 - Your rights if Southwest DEFAULTS or experiences other financial difficulties. ADDITIONAL MECHANICS Form, Exchange and Transfer. The debt securities will be issued: - only in fully registered form; - without interest coupons; and - in denominations that are even multiples of $1,000. You may have your debt securities divided into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. This is called an exchange. You may exchange or transfer debt securities at the office of the trustee. The trustee acts as Southwest's agent for registering debt securities in the names of holders and transferring debt securities. Southwest may change this appointment to another entity or perform these functions itself. The entity performing the role of maintaining the list of registered holders is called the security registrar. It will also perform transfers. You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership. If Southwest has designated additional transfer agents, they are named in the prospectus supplement. Southwest may cancel the designation of any particular transfer agent. Southwest may also approve a change in the office through which any transfer agent acts. If the debt securities are redeemable, Southwest may block the transfer or exchange of debt securities for a period beginning 15 days before the day Southwest mails the notice of redemption, in order to freeze the list of holders to prepare the mailing. Southwest may also refuse to register transfers or exchanges of debt securities selected for redemption, except that Southwest will continue to permit transfers and exchanges of the unredeemed portion of any debt security being partially redeemed. Payment and Paying Agents. Southwest will pay interest to you if you are a direct holder listed in the trustee's records at the close of business on a particular day in advance of each due date for interest, even if you no longer own the debt security on the interest due date. That particular day, usually about two weeks in advance of the interest due date, is called the regular record date and is stated in the prospectus supplement. Holders buying and selling debt securities must work out between them how to compensate for the fact that Southwest will pay all the interest for an interest period to the one who is the registered holder on the regular record date. The most common manner is to adjust the sales price of the securities to pro rate interest fairly between buyer and seller. This prorated interest amount is called accrued interest. Southwest will pay interest, principal and any other money due on the debt securities at the corporate trust office of the trustee in Dallas, Texas. That office is currently located at 2001 Ross Avenue, Suite 2700, Dallas, Texas 75201. You must make arrangements to have your payments picked up at or wired from that office. Southwest may also choose to pay interest by mailing checks. STREET NAME AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW THEY WILL RECEIVE PAYMENTS. Southwest may also arrange for additional payment offices, and may cancel or change these offices, including its use of the trustee's corporate trust office. These offices are called paying agents. Southwest may also choose to act as its own paying agent. Southwest must notify you of changes in the paying agents for any particular series of debt securities. 5 Notices. Southwest and the trustee will send notices regarding the debt securities only to direct holders, using their addresses as listed in the trustee's records. Regardless of who acts as paying agent, all money paid by Southwest to a paying agent that remains unclaimed at the end of two years after the amount is due to direct holders will be repaid to Southwest. After that two-year period, you may look only to Southwest for payment and not to the trustee, any other paying agent or anyone else. SPECIAL SITUATIONS Mergers and Similar Events. Southwest is generally permitted to consolidate or merge with another corporation. We are also permitted to sell or convey all or substantially all of our assets to another corporation. However, we may not take any of these actions unless all of the following conditions are met: Where Southwest consolidates or merges out of existence or sells or conveys all or substantially all of its assets, the other corporation must be organized under the laws of a state or under federal law, and it must agree to be legally responsible for the debt securities. Immediately after the merger, sale of assets or other transaction Southwest must not be in default on the debt securities. A default for this purpose would also include any event that would be an event of default if the requirements for giving Southwest default notice or Southwest's default having to exist for a specific period of time were disregarded. MODIFICATION AND WAIVER There are three types of changes Southwest can make to the indenture and the debt securities. Changes Requiring Your Approval. First, there are changes that cannot be made to your debt securities without your specific approval. Following is a list of those types of changes: - extend the stated maturity of the principal or interest on a debt security; - reduce any amounts due on a debt security; - reduce the amount of principal payable on an original discount security upon acceleration of the maturity of the debt security following a default; - impair your right to sue for payment; and - reduce the percentage of the principal amount of debt securities of any series or all series (voting as one class) the consent of which is needed to modify or amend the indenture; Changes Requiring a Vote. The second type of change to the indenture and the debt securities is the kind that requires a vote in favor by the holders of debt securities owning at least 66 2/3% of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect the interest of holders of the debt securities described in the next paragraph. Southwest may obtain a waiver of a past default from the holders of debt securities owning a majority of the principal amount of the particular series affected. However, Southwest cannot obtain a waiver of a payment default unless Southwest obtains an individual consent to the waiver from every holder. Changes Not Requiring Approval. The third type of change to the indenture and the debt securities does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes that would not adversely affect the interests of holders of the debt securities. Holders of debt securities will also not be eligible to vote if the debt securities have been fully defeased as described below under "Defeasance." STREET NAME AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW 6 APPROVAL MAY BE GRANTED OR DENIED IF SOUTHWEST SEEKS TO CHANGE THE INDENTURE OR THE DEBT SECURITIES OR REQUEST A WAIVER. ABSENCE OF RESTRICTIVE COVENANTS The indenture does not contain any promises by Southwest on how it will operate its business, and does not restrict Southwest's ability to incur debt or grant liens on its assets. If Southwest determines to include such a promise for the benefit of a particular series of debt securities, such promise, or restrictive covenant, will be described in the prospectus supplement relating to that series of debt securities. DEFEASANCE Southwest may be completely released from its payment and other obligations on the debt securities. The following discussion of defeasance will be applicable to your series of debt securities only if Southwest chooses to have them apply to that series. If Southwest does so choose, it will state that in the prospectus supplement. If Southwest obtains a ruling from the Internal Revenue Service or there is a change in federal tax law, as described below, Southwest can legally release itself from any payment or other obligations on the debt securities, called full or legal defeasance, if Southwest puts in place the following other arrangements for you to be repaid: - Southwest must deposit in trust for your benefit and the benefit of all direct holders of the debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. - There must be a change in federal tax law or a ruling from the Internal Revenue Service that lets Southwest make the above deposit without causing you to be taxed on the debt securities any differently than if Southwest did not make the deposit and just repaid the debt securities. Under current federal tax law, the deposit and Southwest's legal release from the debt securities would be treated as though we took back your debt securities and gave you your share of the cash and notes or bonds deposited in trust. In that event, you could recognize gain or loss on the debt securities you give back to Southwest. - Southwest must deliver to the trustee a legal opinion of Southwest's counsel confirming, among other things, the tax law change described above. If we are able to fully defease the debt securities, as described above, you would have to rely solely on the trust deposit for repayment on the debt securities. You could not look to Southwest for repayment. DEFAULT AND RELATED MATTERS Ranking. The debt securities are not secured by any of Southwest's property or assets. Accordingly, your ownership of debt securities means you are one of Southwest's unsecured creditors. The debt securities are not subordinated to any of Southwest's other debt obligations and therefore they rank equally with all of Southwest's other unsecured and unsubordinated indebtedness. Events of Default. You will have special rights if an event of default occurs and is not cured, as described later in this subsection. What is an Event of Default? The term "event of default" means any of the following: - Southwest does not pay the principal or any premium on a debt security when due. - Southwest does not pay interest on a debt security within 30 days of its due date. - Southwest remains in breach of any other covenant or agreement in the indenture for 90 days after it receives a notice of default stating it is in breach. The notice must be sent by either the trustee or holders of 25% of the outstanding principal amount of debt securities of the affected series. 7 - Southwest defaults on any indebtedness for borrowed money totaling over $50,000,000 and Southwest's obligation to repay such indebtedness is accelerated, and this repayment obligation remains accelerated for 10 days after Southwest receives a notice of default by the trustee or holders of 25% of the outstanding principal amount of the affected debt securities. - Southwest files for bankruptcy or certain other events in bankruptcy, insolvency or reorganization occur. Remedies if an Event of Default Occurs. If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the debt securities of the affected series may declare the entire principal amount (or, in the case of original issue discount securities, the portion of the principal amount that is specified in the terms of the affected debt security) of all the debt securities of that series, plus accrued interest, to be due and immediately payable. This is called a declaration of acceleration of maturity. However, a declaration of acceleration of maturity may be cancelled, but only before a judgment or decree based on the acceleration has been obtained, by the holders of at least a majority in principal amount of the debt securities of the affected series. Reference is made to the prospectus supplement relating to any series of debt securities which are original issue discount securities for the particular provisions relating to acceleration of the maturity of a portion of the principal amount of original issue discount securities upon the occurrence of an event of default and its continuation. Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability, called an indemnity. If reasonable indemnity is provided, the holders of a majority of the outstanding principal amount of the securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the indenture. Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur: - You must give the trustee written notice that an event of default has occurred and remains uncured. - The holders of at least 25% of the outstanding principal amount of all the securities of the relevant series must make a written request that the trustee take action because of an event of default, and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action. - The trustee must have not taken action for 60 days after receipt of the above written request and offer of indemnity and no directions inconsistent with the above written request must have been given to the trustee during such period. However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date. STREET NAME AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW TO GIVE NOTICE OR DIRECTION TO OR MAKE A REQUEST OF THE TRUSTEE AND TO MAKE OR CANCEL A DECLARATION OF ACCELERATION. Southwest will furnish to the trustee every year a written statement of certain of its officers certifying that to their knowledge Southwest is in compliance with the indenture and the debt securities, or else specifying any default and indicating the nature and status of the default. 8 CONCERNING THE TRUSTEE The trustee under the indenture is U.S. Trust Company of Texas, N.A. The indenture contains certain limitations on the right of the trustee, should it become a creditor of Southwest, to obtain payment of claims in certain cases, or to realize for its own account on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in certain other transactions; however, if it acquires any conflicting interest (as described in the indenture) it must eliminate such conflict or resign. PLAN OF DISTRIBUTION Southwest may sell debt securities: - to or through underwriting syndicates represented by managing underwriters; - through one or more underwriters without a syndicate for them to offer and sell to the public; - through dealers or agents; and - to investors directly in negotiated sales or in competitively bid transactions. Any underwriter or agent involved in the offer and sale of any series of the debt securities will be named in the prospectus supplement. The prospectus supplement for each series of debt securities will describe: - the terms of the offering of those debt securities, including the name of the agent or the name or names of any underwriters; - the public offering or purchase price; - any discounts and commissions to be allowed or paid to the agent or underwriters and all other items constituting underwriting compensation; - any discounts and commissions to be allowed or paid to dealers; and - other specific terms of the particular debt securities. Only the agents or underwriters named in a prospectus supplement are agents or underwriters in connection with the debt securities being offered by that prospectus supplement. Underwriters, agents and dealers may be entitled, under agreements with Southwest, to indemnification against certain civil liabilities, including liabilities under the Securities Act of 1933. Underwriters to whom debt securities are sold by Southwest for public offering and sale are obliged to purchase all of those particular debt securities if any are purchased. This obligation is subject to certain conditions and may be modified in the applicable prospectus supplement. Each series of debt securities will be a new issue of securities and will not have an established trading market. Unless otherwise indicated in the applicable prospectus supplement, Southwest will not list any series of debt securities on an exchange. No assurance can be given that you will be able to resell any debt securities that you may purchase. Underwriters, dealers or agents may engage in transactions with, or perform services for, Southwest or its affiliates in the ordinary course of business. VALIDITY OF THE DEBT SECURITIES Unless otherwise indicated in the applicable prospectus supplement, the validity of the debt securities offered hereby will be passed upon for us by Deborah Ackerman, Vice President -- General Counsel. 9 EXPERTS Ernst & Young, LLP, independent auditors, have audited our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2000, as set forth in their report, which is incorporated by reference in this prospectus and elsewhere in the registration statement.
