UAL Corporation and Subsidiary Companies Notes to Consolidated Financial Statements (Unaudited) ------------------------------------------------------ The Company - ----------- UAL Corporation ("UAL") is a holding company whose principal subsidiary is United Air Lines, Inc. ("United"). Interim Financial Statements - ---------------------------- The consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to or as permitted by such rules and regulations, although UAL believes that the disclosures are adequate to make the information presented not misleading. In management's opinion, all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the results of operations for the three and six month periods have been made. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in UAL's Annual Report on Form 10-K for the year 1995. Employee Stock Ownership Plans - ------------------------------ Pursuant to amended labor agreements which provide for wage and benefit reductions and work-rule changes which commenced July 1994, UAL has agreed to issue convertible preferred stock to employees. Notes 2 and 14 of the Notes to Consolidated Financial Statements in the 1995 Annual Report on Form 10-K contain additional discussion of the agreements, stock to be issued to employees and the related accounting treatment. Shares earned in 1995 were allocated in March 1996 as follows: 359,577 shares of Class 2 ESOP Preferred Stock were contributed to the Non-Leveraged ESOP and an additional 312,086 shares were allocated in "book entry" form under the Supplemental Plan. Additionally, 2,402,310 shares of Class 1 ESOP Preferred Stock were allocated under the Leveraged ESOP. Finally, an additional 1,536,986 shares of Class 1 and Class 2 ESOP Preferred Stock have been committed to be released by the company since January 1, 1996. Other Income (Expense) - Miscellaneous - -------------------------------------- "Miscellaneous, net" consisted of the following:
Second Quarter Six-month Period 1996 1995 1996 1995 ---- ---- ---- ---- Foreign exchange gains (losses) $ (1) $ 10 $ (6) $ 2 Minority interests (5) (6) (12) (12) Gains on disposition of property - 3 - 41 Other - (6) (8) (8) ---- ---- ---- ---- $ (6) $ 1 $ (26) $ 23 ==== ==== ==== ====
Income Taxes - ------------ The provisions for income taxes are based on the estimated annual effective tax rate, which differs from the federal statutory rate of 35% principally due to state income taxes and certain nondeductible expenses. Deferred tax assets are recognized based upon UAL's history of operating earnings and expectations for future taxable income. Per Share Amounts - ----------------- In April 1996, the stockholders of UAL Corporation approved an increase in the number of authorized shares of common stock from 100 million to 200 million shares, in connection with a four-for-one split of the corporation's common stock in the form of a 300% dividend for stockholders of record, which occurred effective at the close of business on May 6, 1996. All share and per share data have been retroactively restated to give effect to this stock split. During the three-month and six-month periods ended June 30, 1996, UAL repurchased 1,710 and 2,553 shares, respectively, of its Series B preferred stock at an aggregate cost of $57 million and $84 million, respectively, to be held in treasury. During the three- month and six-month periods ended June 30, 1995, UAL repurchased 420 shares of its Series B preferred stock at a cost of $12 million, to be held in treasury, and issued convertible subordinated debentures in exchange for all of its outstanding Series A preferred stock. These transactions had no effect on earnings; however, the difference between the fair value of the consideration given and the carrying value of the preferred stock acquired is included in the computation of earnings per share. These effects are summarized as follows:
Three Month Period Six Month Period 1996 1995 1996 1995 ---- ---- ---- ---- Primary $(0.18) $ 0.70 $(0.27) $ 0.73 Fully diluted $(0.18) $ 0.61 $(0.25) $ 0.63
Per share amounts were calculated after providing for dividends on preferred stock, including ESOP convertible preferred stock, of $16 million in the 1996 second quarter, $10 million in the 1995 second quarter, $32 million in the 1996 six-month period and $23 million in 1995 six-month period. Primary per share amounts for all periods were based on weighted average common shares and common equivalents outstanding, including ESOP shares committed to be released. In addition, fully diluted per share amounts assume the conversion of convertible debentures (for periods not actually converted) and elimination of related interest. Long-Term Obligations - --------------------- During the six months ended June 30, 1996, UAL repaid prior to maturity $472 million in principal amount of various debt securities, resulting in an extraordinary loss of $59 million, after a tax benefit of $36 million. Of this amount, $230 million was repaid during the second quarter, resulting in a $30 million extraordinary loss, net of tax benefits of $18 million. The securities were scheduled for repayment periodically through 2021. During March and April of 1996, holders of $597 million in principal amount of UAL's outstanding 6 3/8% convertible subordinated debentures exercised their right to convert the debentures into an aggregate of $324 million in cash and 7,623,092 shares of common stock. These conversions resulted in a net reduction to long-term debt of $545 million and an increase of $218 million in additional capital invested. In connection with the financing of certain aircraft accounted for as capital leases, United had on deposit at June 30, 1996 an aggregate 14 billion yen ($128 million) in certain banks and had pledged an irrevocable security interest in such deposits to the aircraft lessors. While this transaction does not qualify as an in-substance defeasance for financial reporting purposes, these deposits will be used to pay off an equivalent amount of recorded capital lease obligations. Short-Term Borrowings - --------------------- In April 1996, United entered into an agreement with a syndicate of banks for a $750 million revolving credit facility expiring in 1999. Interest on drawn amounts under the facility is calculated at floating rates based on the London interbank offered rate (LIBOR) plus a margin which is subject to adjustment based on certain changes in the credit ratings of United's long-term senior unsecured debt. Among other restrictions, the credit facility contains a covenant which restricts United's ability to grant liens on or otherwise encumber certain identified assets with a market value of approximately $1.1 billion. During the second quarter, United reduced the maximum available amount of borrowings under a separate short-term borrowing facility from $270 million to $227 million. Contingencies and Commitments - ----------------------------- UAL has certain contingencies resulting from litigation and claims (including environmental issues) incident to the ordinary course of business. Management believes, after considering a number of factors, including (but not limited to) the views of legal counsel, the nature of contingencies to which UAL is subject and its prior experience, that the ultimate disposition of these contingencies is not expected to materially affect UAL's consolidated financial position or results of operations. At June 30, 1996, commitments for the purchase of property and equipment, principally aircraft, approximated $6.8 billion, after deducting advance payments. An estimated $1.3 billion will be spent during the remainder of 1996, $2.6 billion in 1997, $1.1 billion in 1998, and $1.8 billion in 1999 and thereafter. The major commitments are for the purchase of B777, B747 and B757 aircraft, which are scheduled to be delivered through 2002. United's contract with the Association of Flight Attendants ("AFA") became amendable March 1, 1996. On April 9, 1996, United announced that the flight attendants had rejected a previously announced tentative agreement. United and the AFA are involved in traditional negotiations under the Railway Labor Act, which historically have taken two to three years to complete. While negotiations continue, the terms of United's current flight attendant agreement will remain in effect. Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS LIQUIDITY AND CAPITAL RESOURCES UAL's total of cash and cash equivalents and short- term investments was $720 million at June 30, 1996, compared to $1.143 billion at December 31, 1995. Cash flows from operating activities for the six-month period amounted to $1.040 billion, which was net of $487 million in accelerated pension contributions. Investing activities resulted in cash flows of $95 million, as a decrease in short-term investments was partially offset by additions to property. Financing activities included principal payments under debt and capital lease obligations of $590 million and $64 million, respectively. Included in the debt payments was the retirement of $472 million of long-term debt prior to maturity. Financing activities also included payments of $324 million for conversions of UAL's 6 3/8% convertible debentures and $85 million for repurchases of UAL's Series B preferred stock. In the first six months of 1996, United took delivery of five A320, four B777 and one B757 aircraft. Two of these aircraft were purchased, five were acquired under operating leases and three were acquired under capital leases. Property additions, including aircraft spare parts, facilities and ground equipment, amounted to $372 million, while property dispositions resulted in proceeds of $13 million. At June 30, 1996, commitments for the purchase of property and equipment, principally aircraft, approximated $6.8 billion, after deducting advance payments. An estimated $1.3 billion will be spent during the remainder of 1996, $2.6 billion in 1997, $1.1 billion in 1998, and $1.8 billion in 1999 and thereafter. The major commitments are for the purchase of B777 aircraft, B747 aircraft and B757 aircraft, which are scheduled to be delivered through 2002. Funds necessary to finance aircraft acquisitions are expected to be obtained from internally generated funds, irrevocable external financing arrangements or other external sources. In April 1996, United entered into an agreement with a syndicate of banks for a $750 million revolving credit facility expiring in 1999. Interest on drawn amounts under the facility is calculated at floating rates based on the London interbank offered rate (LIBOR) plus a margin which is subject to adjustment based on certain changes in the credit ratings of United's long-term senior unsecured debt. Among other restrictions, the credit facility contains a covenant which restricts United's ability to grant liens on or otherwise encumber certain identified assets with a market value of approximately $1.1 billion. During the second quarter, United reduced the maximum available borrowings under a separate short-term borrowing facility from $270 million to $227 million. In April 1996, the stockholders of UAL Corporation approved an increase in the number of authorized shares of common stock from 100 million to 200 million shares, in connection with a four-for-one split of the corporation's common stock in the form of a 300% dividend for stockholders of record, which occurred effective at the close of business on May 6, 1996. RESULTS OF OPERATIONS UAL's results of operations for interim periods are not necessarily indicative of those for an entire year, as a result of seasonal factors to which United is subject. First and fourth quarter results are normally affected by reduced travel demand in the fall and winter and United's operations, particularly at its Chicago and Denver hubs and at certain east coast cities, are adversely affected by winter weather on occasion. The results of operations in the airline business historically fluctuate significantly in response to general economic conditions. This is because small fluctuations in yield (passenger revenue per revenue passenger mile) and cost per available seat mile can have a significant effect on operating results. UAL anticipates industrywide fare levels, increasing low-cost competition, general economic conditions, fuel costs, international governmental policies and other factors will continue to affect its operating results. Consistent with UAL's strategic plan and the company's focus on attracting more high yield passengers, management is considering making a substantial investment in its on-board product including new aircraft seats and new inflight entertainment products. If this plan is approved, an assessment will have to be made as to the status of the carrying value of the seats and inflight entertainment products currently in service. Accordingly, depending upon the ultimate plan adopted and the period over which such a replacement program would take place, the company may be required to either shorten the periods over which the current investments in such assets are being depreciated and/or record a significant one-time additional depreciation provision. It is anticipated this assessment will be made during the third quarter. Summary of Results ------------------ UAL's earnings from operations were $460 million in the first six months of 1996, compared to operating earnings of $340 million in the first six months of 1995. UAL's net earnings were $174 million ($1.56 per share, primary; $1.51 per share, fully diluted), compared to net earnings of $154 million ($2.94 per share, primary; $2.76 per share, fully diluted) during the same period in 1995. The 1996 six-month period includes an extraordinary loss of $59 million ($0.77 per share, primary; $0.73 per share, fully diluted) on early extinguishment of debt. In the second quarter of 1996, UAL's earnings from operations were $398 million compared to operating earnings of $302 million in the second quarter of 1995. UAL had net earnings in the 1996 second quarter of $196 million ($2.01 per share, primary; $1.99 per share, fully diluted), compared to net earnings of $151 million in the same period of 1995 ($3.00 per share, primary; $2.73 per share, fully diluted). The 1996 second quarter results include an extraordinary loss of $30 million ($0.36 per share) on early extinguishment of debt. The 1996 and 1995 per share amounts also include the effects on equity of the repurchase of Series B preferred stock and exchange of Series A preferred stock for convertible debentures. See "Per Share Amounts" in the notes to consolidated financial statements. Management believes that a more complete understanding of UAL's results can be gained by viewing them on a pro forma, "fully distributed" basis. This presentation considers all ESOP shares which will ultimately be distributed to employees throughout the ESOP (rather than just the shares committed to be released) to be immediately outstanding and thus fully distributed. Consistent with this presentation, the ESOP compensation expense is excluded from fully distributed net earnings and ESOP convertible preferred stock dividends are not deducted from earnings attributable to common stockholders. A comparison of results reported on a fully distributed basis to results reported under generally accepted accounting principles (GAAP) is as follows:

United's revenue per available seat mile increased 6% to 10.30 cents. Passenger revenues increased $302 million (9%) due to a 4% increase in yield to 12.48 cents and a 4% increase in revenue passenger miles. The following analysis by market is based on information reported to the U.S. Department of Transportation: Latin America revenue passenger miles increased 7% over the same period last year, with a nearly 5% increase in yield. In the Pacific, revenue passenger miles also increased 7%; however, yield decreased 10% from the same period last year, largely due to a weakening Japanese yen. Domestic revenue passenger miles increased 4% and Atlantic revenue passenger miles increased 2%. Domestic yield increased 11% as a result of a larger proportion of high yield business traffic and fare levels influenced by the expiration of the Federal passenger excise tax. Available seat miles increased 3% systemwide, reflecting increases of 6% in Latin America, 4% in the Pacific and 2% on Domestic routes. The system passenger load factor increased 1.2 points to 73.1%. Cargo revenues increased $7 million (4%) primarily due to increased freight revenues. Freight ton miles increased 3% and mail ton miles increased 4%. However, a 1% higher freight yield was offset by a 3% decrease in mail yield. Other operating revenues increased $40 million (17%) due to increases in Mileage Plus partner-related revenues and contract maintenance and fuel sales to third parties. Operating expenses increased $253 million (7%) and United's cost per available seat mile increased 4%, from 8.91 cents to 9.30 cents, including ESOP compensation expense. Without the ESOP compensation expense, United's cost per available seat mile would have increased 3%, from 8.64 cents to 8.89. ESOP compensation expense increased $60 million (56%), reflecting the increase in the estimated average fair value of ESOP preferred stock committed to be released to employees as a result of UAL's higher common stock price. Aircraft maintenance increased $23 million (24%) due to the timing of maintenance cycles. Fuel expense increased $81 million (20%) due to a 2% increase in consumption and a 17% increase in the average price per gallon of fuel to 69.0 cents. The federal jet fuel tax which went into effect October 1, 1995, accounted for approximately $20 million of this increase. Purchased services increased $31 million (12%) due principally to volume-related increases in computer reservations fees and credit card discounts. Other operating expenses increased $32 million (7%) due principally to costs associated with sales to third parties of fuel, contract maintenance and other work. Depreciation and amortization increased $8 million (5%) due primarily to the acquisition of 39 aircraft off operating leases in 1995 and new B777 aircraft accounted for under capital leases. Aircraft rent decreased $20 million (8%) due to a decrease in the number of aircraft on operating leases. Other expense amounted to $27 million in the second quarter of 1996 compared to $51 million in the second quarter of 1995. Interest capitalized, primarily on aircraft advance payments, increased $14 million (140%). Interest expense decreased $27 million (27%) due to the prepayment of long-term debt in 1995 and 1996. Equity in earnings of affiliates increased $4 million (31%) due primarily to higher Galileo earnings resulting from increased booking revenues. Included in "Miscellaneous, net" in the 1996 second quarter were foreign exchange losses of $1 million compared to foreign exchange gains of $10 million in the 1995 second quarter. Six Months 1996 Compared with Six Months 1995 - --------------------------------------------- Operating revenues increased $749 million (11%). United's revenue per available seat mile increased 7% to 9.94 cents. Passenger revenue increased $660 million (10%), due principally to a 5% increase in revenue passenger miles and a 5% increase in yield to 12.36 cents. The following analysis by market is based on information reported to the U.S. Department of Transportation: Latin America revenue passenger miles increased 5% over the same period last year, with a 1% increase in yield. In the Pacific, revenue passenger miles increased 8%; however, yield decreased 7% from the same period last year, largely due to a weakening Japanese yen. Atlantic revenue passenger miles increased 8% and domestic revenue passenger miles increased 4%. Domestic yield increased 10% as a result of a larger proportion of high yield business traffic and fare levels influenced by the expiration of the Federal passenger excise tax. Available seat miles increased 3% systemwide, reflecting increases of 8% in Latin America, 5% in the Atlantic, 4% in the Pacific and 2% on Domestic routes. The system passenger load factor increased 1.4 points to 70.9%. Cargo revenues increased $7 million (2%) due primarily to increased mail revenues. Mail ton miles increased 7% and freight ton miles increased 3%. However, yields for both mail and freight decreased 2% from the same period in 1995. Other operating revenues increased $82 million (17%) due to increases in Mileage Plus partner-related revenues and contract maintenance and fuel sales to third parties. Operating expenses increased $629 million (9%) and United's cost per available seat mile increased 6%, from 8.82 to 9.35 cents, including ESOP compensation expense. Without the ESOP compensation expense, United's 1996 six month cost per available seat mile would have been 8.93 cents, an increase of 4% from 1995. ESOP compensation expense increased $134 million (68%), reflecting the increase in the estimated average fair value of ESOP stock committed to be released to employees as a result of UAL's higher common stock price. Aircraft fuel increased $177 million (22%) due to a 3% increase in consumption and a 19% increase in the average price per gallon of fuel to 68.7 cents. The federal jet fuel tax which went into effect October 1, 1995, accounted for approximately $40 million of this increase. Purchased services increased $68 million (14%) due principally to volume-related increases in computer reservations fees, credit card discounts and communication charges. Aircraft maintenance increased $28 million (14%) due to the timing of maintenance cycles. Other operating expenses increased $90 million (10%) due principally to costs associated with sales to third parties of fuel, contract maintenance and other work. Landing fees and other rent increased $39 million (10%) due to increased facilities rent, particularly at the new Denver International Airport. Depreciation and amortization increased $35 million (10%) due primarily to the acquisition of 39 aircraft off-lease in 1995 and new B777 aircraft accounted for under capital leases. Aircraft rent decreased $30 million (6%) due to a decrease in the number of aircraft on operating leases. Other expense amounted to $78 million for the first six months of 1996 compared to $83 million for the first six months of 1995. Interest capitalized, primarily on aircraft advance payments, increased $17 million (77%). Interest expense decreased $44 million (22%) due to the prepayment of long-term debt in 1995 and 1996. Equity in earnings of affiliates increased $10 million (37%) due primarily to higher Galileo earnings resulting from increased booking revenues. In addition, the first six months of 1995 included a $41 million pre-tax gain on disposition of aircraft owned by Air Wisconsin, Inc. OUTLOOK FOR 1996 Given first and second quarter trends, available seat miles are expected to grow approximately 3% for the full year over 1995, with a 1 to 2 point increase in load factor. Third quarter yields are expected to remain strong. It is likely that the Federal passenger excise tax will be reinstated during the third quarter; however, it is uncertain whether the tax will remain in effect permanently. As a result, United is unable to determine at this time, what effect, if any, a temporary or permanent reinstatement of the excise tax will have on the domestic pricing environment. Pacific unit revenue is expected to turn positive relative to 1995, assuming that the negative yen exchange rate effect is less than in the second quarter. Unit cost for the full year, excluding the ESOP compensation expense, is expected to increase approximately 3% due largely to volume-driven costs and fuel prices. Net interest expense for the year should be lower due to the early repayments of relatively high-interest rate debentures and the conversion of $597 million in principal amount of 6 3/8% convertible debentures. The information included in the previous paragraph is forward-looking and involves risks and uncertainties that could result in actual results differing materially from expected results. It is not reasonably possible to itemize all of the many factors and specific events that could affect the outlook of an airline operating in the global economy. Some factors that could significantly impact expected capacity, yields and expenses include the airline pricing environment, willingness of customers to travel, fuel costs, low-fare carrier expansion, capacity decisions of other carriers, actions of the U.S. and foreign governments, foreign currency exchange rate fluctuations, the price of UAL common stock, inflation, the general economic environment, and other factors discussed herein and in UAL's 1995 Annual Report on Form 10-K. Part II ------- Other Information ----------------- Item 1. Legal Proceedings. - ------ ----------------- Travel Agency Commission Litigation - On February 13, l995 and dates thereafter United Air Lines, Inc. ("United") and six other airlines were sued in various courts around the nation by travel agents and the American Society of Travel Agents claiming as a class action that the carriers acted collusively in violation of federal antitrust laws when they imposed a cap on ticket sales commissions payable to travel agencies by the carriers. The cases are now consolidated before the federal court in Minneapolis. The court, on August 23, 1995, denied the plaintiffs' motion for preliminary injunction as well as the defendants' motion for summary judgment. As relief, the plaintiffs seek an order declaring the carriers' commission cap action to be illegal and the recovery of damages (trebled) to the agencies resulting from that action. One of the six co- defendants, TWA, entered into a court-approved settlement agreement. On May 28, 1996, the defendants, upon the close of discovery, filed renewed motions for summary judgment. Oral argument on the motions was heard on July 26, 1996. The case has been set for trial on September 4, 1996. Fry v. UAL Corp. - On February 21, 1990, a purported class action complaint was filed in the U.S. District Court for the Northern District of Illinois, Eastern Division. This complaint was brought by several UAL Corporation ("UAL") stockholders, purportedly on behalf of all of UAL stockholders who sold puts or common stock from October 29, 1987 through December 8, 1987. The complaint alleged that UAL committed common law fraud and violated Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and the Illinois Deceptive Trade Practices Act by falsely announcing that it intended to distribute proceeds of sales of non-core businesses as a special dividend, when in fact it was negotiating a cash tender offer for the buyback of shares. Plaintiffs claimed $160 million in damages, plus attorneys' fees, fees and costs of plaintiff's accountants and experts and other costs and disbursements. UAL's motion for summary judgment was granted on August 11, 1995, and that decision was affirmed by the Seventh Circuit on May 23, 1996. Mileage Plus Class Actions - As reported in UAL's Form 10-Q for the quarter ended March 31, 1996, on December 10, 1993, January 18, 1994, November 3, 1994 and February 9, 1995, class actions were brought in the Circuit Court of Cook County, Illinois, Chancery Division, on behalf of members of the Mileage Plus Program. The actions, as amended, claimed that various changes instituted by United in the Mileage Plus Program breached United's contracts with its program members. In December 1994, one of the cases was dismissed by the court on United's motions, the dismissal subsequently affirmed by the Illinois Appellate Court on June 7, 1996. On October 13, 1995, the court granted United's motion to dismiss the three remaining cases with prejudice but permitted the plaintiffs to file an amended complaint. The amended complaint, filed solely on behalf of program members who joined prior to 1988, was dismissed by the court on United's motion on March 29, 1996. On April 29, 1996, the plaintiffs filed an appeal with the Appellate Court of Illinois for the First District. GEC-Marconi Claim - On April 4, 1996 United filed suit in the Circuit Court of Cook County, Illinois, Law Division, against GEC- Marconi Inflight Systems Overseas, Ltd. ("GMIS"), its 777 inseat video vendor, claiming breach of contract for GMIS's failure to deliver the contracted product in the specified time frame, and seeking monetary and injunctive relief. United also named in the suit GEC-Marconi Inflight Systems, Inc. ("GMIS, Inc."), its 777 video maintenance provider, seeking declaratory relief on the maintenance contract. On July 19, 1996 GMIS and GMIS, Inc. filed a counterclaim against United seeking in excess of $240 million for various alleged breaches of contract by United, plus consequential damages and attorney's fees and costs, relating to the same product purchase agreement (which, in addition, included a 747 and 767 retrofit order that United terminated on April 4, 1996) and maintenance service agreement which form the basis of United's complaint, as well as an alleged June 1996 "agreement" that had been the subject of negotiations between the parties but was never signed by United regarding interim arrangements between the parties. GMIS and GMIS, Inc. also seek injunctive relief to enforce the alleged "agreement" and prevent United from obtaining substitute goods from other vendors. On August 1, GMIS and GMIS, Inc. filed an emergency motion on the claims for injunctive relief. The court has set August 28 as the hearing date on the issue of whether, as a matter of law, GMIS and GMIS, Inc. should be denied its emergency motion. GMIS and GMIS, Inc. also filed a motion to dismiss United's complaint. Item 2. Changes in Securities. - ------ --------------------- On April 26, 1996 UAL Corporation filed an amendment to its Restated Certificate of Incorporation with the Secretary of State of Delaware which increased the number of authorized shares of its Common Stock, $.01 par value ("Common Stock"), from 100,000,000 shares to 200,000,000 shares in connection with a four-for-one stock split of the Common Stock in the form of a 300% stock dividend to holders of record, which occurred effective at the close of business on May 6, 1996.

                        FOURTH AMENDMENT
                         UAL CORPORATION
                  EMPLOYEE STOCK OWNERSHIP PLAN
                 (Effective as of July 12, 1994)


         By virtue and in exercise of the amending power reserved
to UAL Corporation (the "Company") under Section 13.1(a) of the
UAL Corporation Employee Stock Ownership Plan (effective as of
July 12, 1994) (the "Plan"), which amending power thereunder is
subject to the approval of the Air Line Pilots Association
International ("ALPA") and the International Association of
Machinists and Aerospace Workers (the "IAM"), the Company hereby
amends the Plan, subject to the approval of ALPA and the IAM, as
follows, effective as of August 1, 1996 (except as specified
below).
          
          1.  The following new paragraph is added immediately
following the third paragraph of the material labelled
"Transaction" which precedes Section 1:

          "The parties to the Recapitalization Agreement have
     recognized that the value of the Common Stock has increased
     significantly since the effective date of the Plan.  That
     increase is expected to result in an increase in the price
     at which the Trustee will acquire Class 1 Non-Voting
     Preferred Stock starting in 1996.  As a result of the
     significant price increase and limitations imposed under the
     Internal Revenue Code, the parties to the Recapitalization
     Agreement anticipate that the portion of the underlying
     shares of Preferred Stock which will be available under Part
     A may be reduced from 78.15% starting in 1996, as
     contemplated by Section 1.6(q) of the Recapitalization
     Agreement.  Any reduction in the Class 1 Non-Voting
     Preferred Stock under Part A for a Plan Year will be offset
     by a corresponding increase for that year in the shares of
     Preferred Stock under Part B and the Supplemental Plan."
           
          2.  The material labelled "Part A" which precedes
 Section 1 is amended by adding the following new paragraph to
 the end of such material:

          "For the Plan Years beginning on and after January 1,
     1996, the foregoing percentages will be adjusted as set
     forth in Section 5.4(a)(i)(A) to take into account the
     expected limitations on the amount of shares of Preferred
     Stock which can be delivered under Part A because of
     limitations under the Code.  It is expected that such Code
     limitations will result in an overall reduction of the
     number of shares of Preferred Stock which can be delivered
     in Part A. It is also expected that the total number of
     shares to be delivered in Part A to the Management and
     Salaried Employee Group will be unchanged, that the total
     number of shares to be delivered in Part A to the IAM
     Employee Group will be reduced, and that the total number of
     shares to be delivered in Part A to the ALPA Employee Group
     may be reduced.  The Company shall, pursuant to an agreement
     entered into pursuant to Section 1.6(q) of the
     Recapitalization Agreement among the Company and the unions
     representing the members of the ALPA and IAM Employee
     Groups, determine the number of shares which are expected to
     be delivered under Part A, determine the relevant
     percentages among the Employee Groups, and cause any
     reduction in the shares delivered under Part A to each
     Employee Group to be offset by a corresponding increase in
     the number of shares delivered under Part B and the
     Supplemental Plan to that Employee Group, so that the total
     number of shares delivered to each Employee Group will be
     unchanged."

          3.  Section 1(p) is amended by adding the following to
the end of the Section, it being understood that the language set
forth below is intended only as an explanation of the original
intent of the Plan and not as a substantive change to the Plan,
and is therefore effective July 12, 1994:
          
          "Compensation shall not include amounts paid in an
     employee contest or drawing of any type."

          4.  The following is added after the first sentence of
Section 3.1(a)(i):

          "For Plan Years 1996 through 1999 inclusive, the
     Company's contribution under Part A (and the corresponding
     principal payment due for the initial year of each
     Additional Acquisition Loan entered into for such years)
     shall be limited to the maximum contribution which the
     Company reasonably determines in consultation with its
     advisers can be made consistent with (w) satisfaction of the
     principles set forth in Section 1.6(l) of the
     Recapitalization Agreement, (x) achieving a high degree of
     certainty that the limits of Code Section 415(c)(6) shall
     not be exceeded, (y) avoiding an allocation which would be
     expected to cause all members of an Employee Group to exceed
     the limits of Code Section 415(c), and (z) limiting the
     release of shares of Class 1 Non-Voting Preferred Stock from
     the suspense accounts under the Acquisition Loans so that
     there are available for allocation that year sufficient
     shares of Class 2 Non-Voting Preferred Stock for each
     Employee Group to permit appropriate allocations in the
     Supplemental ESOP to individuals whose allocations reached
     the limit of Code Section 415(c).  The Company's
     contribution shall be determined under the Agreement
     Pursuant to Section 1.6(q) of the Recapitalization Agreement
     (the "1.6(q) Agreement") entered into by the Company, ALPA
     and the IAM, which provides that the amount of the
     contribution shall not be made by reconsidering the
     principles set forth in clauses (w) through (z), but shall
     instead be made by using the same methodology which was used
     by the Company (and verified by the Committee) for the
     determination of the Revised Class 1 Decimal under the
     1.6(q) Agreement, and that such methodology shall be applied
     by using such updated data as may be reasonably available to
     the Company prior to the determination of the contribution."
          
          5.  Section 5.4(a)(i)(A) is amended by adding the
 following to the end of the Section:

          "For Class 1 Non-Voting Preferred Stock released for
     Plan Years beginning on or after January 1, 1996 and before
     January 1, 2000, the allocation percentage shall be
     determined by the Company as described below.  There shall
     be determined the number of shares of Class 1 Non-Voting
     Preferred Stock available for allocation for the Plan Year,
     which is equal to the sum of (x) the number of shares of
     Class 1 Non-Voting Preferred Stock which will be released
     for the Plan Year on account of repayment of all Acquisition
     Loans and (y) the number of shares held in the suspense
     account referred to in Section 5.5(f) on account of excess
     contributions in the preceding Plan Year.  The number of
     shares of Class 1 Non-Voting Preferred Stock to be allocated
     for the Plan Year on behalf of dividends paid on previously-
     allocated shares shall be determined for each Employee
     Group.  The allocation percentage for the Management and
     Salaried Employee Group shall be the percentage which will
     result in a total allocation of 497,983.6564 shares of
     Class 1 Non-Voting Preferred Stock, including the shares to
     be allocated on account of dividends paid on previously-
     allocated shares.  The percentage to be allocated to the
     members of the IAM Employee Group shall be the least of (xx)
     the percentage which would result in a total allocation to
     the IAM Employee Group of 1,129,952.550 shares of Class 1
     Non-Voting Preferred Stock for such Plan Year, including
     shares to be allocated based upon dividends paid on
     previously-allocated shares, (yy) the percentage which is
     expected to result in the allocation of the sum of (i) the
     shares to be allocated based upon dividends paid on
     previously-allocated shares, plus (ii) the amount the
     Company reasonably determines, in consultation with its
     advisers, as the maximum allocation which can be made
     consistent with avoiding an allocation which would be
     expected to cause all members of the IAM Employee Group to
     exceed the limits described in Section 5.4(a)(iii), or (zz)
     the percentage which was contemplated for the allocation to
     the IAM Employee Group upon consummation of the Additional
     Acquisition Loan entered into during such Plan Year.  The
     allocation percentage to the ALPA Employee Group shall be
     one minus the sum of the allocation percentage to the
     Management and Salaried Employee Group and the IAM Employee
     Group."
          
          6.  Section 5.4(a)(iii) is amended by adding the
following to the end of the Section:
          
          "Effective for Plan Years beginning on or after January
     1, 1996, for purposes only of allocations of contributions
     under Part A, the amount of the limitation under Code
     Section 415(c) shall be reduced by an amount which is
     reasonably estimated by the Company for each Employee Group,
     as necessary to permit the allocation of Voting Preferred
     Stock under Section 5.4(c)(i), without violating the
     limitation of Code Section 415(c).  For this purpose, the
     amount of the reduction in the limitation may be estimated
     in any reasonable way, and such estimation may be made on a
     group-wide, rather than an individual basis; the amount of
     the reduction in the limitation need not be the same for
     each Employee Group."
          
          7.  Section 5.4(a)(viii) shall be redesignated as
clause (ix), the first word of such clause shall be changed from
"eighth" to "ninth", the reference "clauses (i) through (vii)"
shall be changed to a reference to "clauses (i) through (viii)",
and there shall be inserted a new clause (viii) as follows:

          "(viii) Eighth.  If the allocation of Employer
     contributions described in clause (vii) results in a
     violation of Code Section 415(c) for all members of any
     Employee Group (after reallocating any excess allocation
     owing to members of such Employee Group), then the excess
     allocation, and the shares released from repayment of
     Acquisition Loans resulting from such excess allocation,
     shall be placed in the suspense account referred to in
     Section 5.5(f), and the tentative allocations shall become
     final.  For this purpose, shares shall first be allocated in
     any Plan Year from the suspense account referred to in
     Section 5.5(f), and then from the shares released on account
     of repayment of Acquisition Loans, in the order the
     Acquisition loans were entered into."
          
          8.  Section 5.5(d) is amended by adding the following
 to the end of the Section:
          
          "For Plan Years beginning on or after January 1, 1996,
     Part B shall generally continue to be reduced before Part A,
     but Part A shall be reduced prior to Part B to the extent
     set forth in the provisions of Section 5.4(a)(iii) which
     refer to Voting Preferred Stock."

          9.  Section 5.5(f) is amended to read as follows:

          "(f) Excess Allocations.  If, after applying the
     allocation provisions under Section 5.4, allocations under
     Section 5.4 would otherwise result in a violation of Code
     Section 415, the ESOP Committee shall reduce Employer
     Contributions for the next limitation year for all
     Participants and shall hold excess amounts in a Suspense
     Account for allocation in a subsequent Plan Year in
     accordance with Reg. Section 1.415-6(b)(6)(iii).  The shares
     of Class 1 Non-Voting Preferred Stock which correspond to
     such excess contribution amounts shall also be held in such
     Suspense Account for allocation to Participants in a
     subsequent Plan Year.  If an amount is held in the Suspense
     Account referred to in this subsection (f) after the
     completion of allocations for any Plan Year, then such
     amount shall be allocated as part of the Employer
     Contribution for the immediately following Plan Year.  Such
     amount shall be included in calculating the allocation
     percentage among the Employee Groups, pursuant to Section
     5.4(a)(i).  Accordingly, in a Plan Year in which amounts
     held in the Suspense Account are allocated, the total
     Employer Contributions, including the amounts held in the
     Suspense Account, shall be allocated according to the
     allocation percentages established under Section 5.4(a)(i).
     The intended result of the allocation is that the Suspense
     Account should not alter the agreed-upon cumulative division
     of shares among the Employee Groups in Parts A and B and the
     Supplemental ESOP."
          
          10.  Section 7.2 is amended, effective as of the date
this amendment is adopted and approved, by adding the following
immediately before the words "provided, however":
     
          "or the Participant is determined to have a Total
     Disability"

          IN WITNESS WHEREOF, the Company has caused this Fourth
Amendment to be executed on July 16, 1996.

                        SUPPLEMENTAL ESOP
                 (Effective as of July 12, 1994)


         By virtue and in exercise of the amending power reserved
to UAL Corporation (the "Company") under Section 13.1(a) of the
UAL Corporation Supplemental ESOP (effective as of July 12, 1994)
(the "Plan"), which amending power thereunder is subject to the
approval of the Air Line Pilots Association International
("ALPA") and the International Association of Machinists and
Aerospace Workers (the "IAM"), the Company hereby amends the
Plan, subject to the approval of ALPA and the IAM, as follows,
effective as of August 1, 1996 (except as specified below).
         
          1.  Section 1.1(c) is amended by adding the following
to the end of the Section:
          
          "For Convertible Shares to be allocated under this Plan
     for Plan Years beginning on or after January 1, 1996, the
     percentages to be allocated shall be determined as follows:
     The number of Convertible Shares to be allocated under this
     Plan shall, for each Plan Year prior to the Plan Year
     beginning January 1, 2000, be the remainder of deducting the
     shares allocated under Part A of the ESOP from 3,073,973.
     For the Plan Year beginning January 1, 2000, the total
     number of shares allocated under this Plan shall equal the
     remaining Convertible Shares to be allocated to all Employee
     Groups, after the allocation under Part A of the ESOP.  The
     number of shares to be allocated to each of the Employee
     Groups for each Plan Year (other than the Plan Year
     beginning January 1, 2000) shall equal, for the ALPA Group,
     the result of deducting the shares allocated under Part A of
     the ESOP for such Plan Year from 1,421,097.718 shares, for
     the IAM Employee Group, the result of deducting the shares
     allocated under Part A of the ESOP for such Plan Year from
     1,141,366.175 shares, and for the Management and Salaried
     Group shall be the result of deducting the shares allocated
     under Part A of the ESOP for such Plan Year from 511,509.107
     shares.  For the Plan Year beginning January 1, 2000, the
     number of shares to be allocated to each Employee Group
     under this Plan shall be the total number of shares
     remaining to be allocated to such Employee Group, after the
     allocations under Part A of the ESOP."

          2.  Section 2.2(a) is amended by adding the following
to the end of the Section:
          
          "Notwithstanding the foregoing, the maximum number of
     Convertible Shares issued under this Plan and the ESOP (Part
     B) shall be the result of deducting from 17,675,345 the
     number of Convertible Shares allocated under Part A."

          3.  Section 3.1(b)(i) is amended to read as follows,
effective as of the date this amendment is adopted and approved:
          
          "(i) as soon as practicable following the Valuation
     Date coinciding with or next following the later of (x) the
     earlier of the Participant's termination of employment with
     the Employer and its Affiliates and the date the Participant
     is determined to have a Total Disability, or (y) December
     31, 1995, the Company shall pay such Participant (or, if
     such Participant is not living at the time for payment, to
     such Participant's Beneficiary) the value of the
     Participant's vested Account; and"
         
          4.  Section 3.1(c)(v) is amended by adding the
following to the end of the Section:
          
          "In the case of any member of the IAM Employee Group
     whose employment with the Employer and its Affiliates is not
     terminated at the time of his election, the foregoing
     sentence shall not apply.  Instead, any such election (or
     modification or revocation thereof) shall be void unless
     made (x) at least one year prior to the Participant's
     termination of employment with the Employer (and its
     Affiliates), (y) for a member of the IAM Employee Group who
     had Convertible Shares allocated to the Participant's
     Account under this Plan for the 1995 Plan Year, by September
     15, 1996, or (z) for a member of the IAM Employee Group who
     did not have Convertible Shares allocated to the
     Participant's Account in this Plan for the 1995 Plan Year,
     by December 31, 1996."

          IN WITNESS WHEREOF, the Company has caused this Fourth
Amendment to be executed on July 16, 1996.

                      AGREEMENT PURSUANT TO
          SECTION 1.6(q) OF RECAPITALIZATION AGREEMENT


         WHEREAS, UAL Corporation, a Delaware Corporation (the
"Company"), Air Line Pilots Association International ("ALPA")
and International Association of Machinists and Aerospace Workers
(the "IAM") are parties to an Amended and Restated Agreement and
Plan of Recapitalization dated March 25, 1994 ("Recapitalization
Agreement");
         
         WHEREAS, the parties to the Recapitalization Agreement
have recognized that due to increases in the price of the common
stock of the Company, it is expected that the Class 1 ESOP
Preferred Stock to be purchased by the Trustee in 1996 and
subsequent years may, unless the number of such shares to be
purchased are adjusted, cause allocations under the ESOP to be in
an amount which would exceed the limitations of Internal Revenue
Code ("Code") Section 415(c); and
         
         WHEREAS, Section 1.6(q) of the Recapitalization
Agreement provides that the parties agree to cooperate to modify
the number of Class 1 ESOP Preferred Shares to be sold and to
make appropriate conforming modifications to the related
documents to avoid allocations in excess of the limitations of
Code Section 415; and

         WHEREAS, this agreement ("Agreement") is entered into
pursuant to Section 1.6(q) of the Recapitalization Agreement.

         NOW, THEREFORE, the Company, ALPA, and the IAM hereby
agree as follows:
          
         1.  Unless otherwise defined in this Agreement,
capitalized terms used in this Agreement shall have the meaning
set forth in the Recapitalization Agreement.
          
         2.  The parties hereto recognize that in order to
satisfy the limitations of Code Section 415, it will likely be
necessary to reduce the number of shares of ESOP Preferred
purchased by the Trustee in 1996 and subsequent years.  It is the
intent of the parties to set forth in this Agreement a revised
method of determining the number of shares of ESOP Preferred to
be offered to the Trustee for purchase pursuant to Section 1.6(e)
of the Recapitalization Agreement.  It is the intent of the
parties hereto that to the extent the number of shares of ESOP
Preferred are reduced under this Agreement, there shall be a
corresponding increase in the number of shares of Supplemental
ESOP Preferred, with the result being that the sum of the ESOP
Preferred and Supplemental ESOP Preferred, on both an annual and
cumulative basis, will be unchanged by this Agreement.
          
         3.  The purchases of ESOP Preferred expected to be
made by the ESOP Trustee in 1996, 1997, 1998, and 1999, shall be
determined as if Section 1.6(e) of the Recapitalization Agreement
provided as follows:

         "(e) At or about July 12, 1996, and at or about the
     next three following anniversaries of July 12, 1996 (each of
     the four July 12 dates a "Measuring Date Anniversary"), the
     Company shall negotiate in good faith with the ESOP Trustee
     to reach an agreement under which the Company shall issue to
     the ESOP Trustee shares of ESOP Preferred at an agreed-upon
     price per share (for each applicable plan year, the
     "Purchase Price").  If such agreement is reached within 30
     days of any Measuring Date Anniversary, then, within five
     days thereafter, the Company shall sell to the ESOP Trustee,
     and the ESOP Trustee shall purchase from the Company,
     pursuant to an agreement substantially in the form of
     Exhibit A to this Agreement, a number of shares of ESOP
     Preferred (with respect to each such year, the "Subsequent
     Shares"), which number of shares shall equal, for each such
     plan year, the Subsequent Year Release Shares (as defined)
     divided by the Subsequent Year Decimal (as defined).
           
         (i)    The term "Subsequent Year Release Shares" shall
                mean, for each such plan year, the excess of

                (xx)  the product of

                      (A) 12/69ths of the Final Number and

                      (B)  the Revised Class 1 Decimal (as
                           defined below) over
                    
                (yy)  the number of Year 1 Remaining Shares and
                      Subsequent Year Remaining Shares (as
                      defined below) (collectively, "Tail
                      Shares") scheduled to be released in such
                      plan year.
                    
         (ii)   The term "Subsequent Year Decimal" shall be
                calculated separately for each such plan year and
                shall mean one minus the product of
                    
                (yy)  a fraction (expressed as a decimal) having
                      a numerator equal to the Dollar Amount and
                      a denominator equal to the Purchase Price
                      for the plan year in question, and
                    
                (zz)  the number of years and fractional years
                      from the end of the plan year for which
                      such shares are being issued to March 31,
                      2000.
                    
         (iii)  The term "Revised Class 1 Decimal" shall mean
                the factor (not to exceed .7815) which is
                determined by the Company no later than each
                Measuring Date Anniversary.  The amount of the
                Revised Class 1 Decimal shall be the amount
                which is reasonably estimated to result in the
                number of Subsequent Year Release Shares which,
                when added to the Tail Shares scheduled to be
                released in such plan year, will maximize the
                Revised Class 1 Decimal consistent with (ww)
                satisfaction of the principles set forth in
                Section 1.6(l), (xx) achieving a high degree of
                certainty that the limits of Internal Revenue
                Code Section 415(c)(6) shall not be exceeded,
                (yy) avoiding an allocation of contributions
                which would cause all members of an Employee
                Group (as defined in the ESOP) to exceed the
                limits of Internal Revenue Code Section 415(c),
                and (zz) limiting the purchase of ESOP Preferred
                so that there can be allocated sufficient shares
                of Supplemental ESOP Preferred for each Employee
                Group to permit appropriate allocations in the
                Supplemental ESOP to individuals whose
                allocations in the ESOP reached the limit of
                Code Section 415(c).  The Company and its
                advisors shall, prior to each Measuring Date
                Anniversary, present to the Committee (as
                defined in the ESOP) the calculation of the
                Revised Class 1 Decimal, and the Committee shall
                review such calculation to verify that the
                Revised Class 1 Decimal was calculated according
                to the methodology described above.  It is the
                understanding of the parties hereto that in
                making the verification referred to in the
                preceding sentence, the members of the Committee
                are acting on behalf of the ALPA (in the case of
                the Committee members appointed by ALPA), the
                IAM (in the case of the Committee members
                appointed by the IAM) and the Company (in the
                case of the Committee member appointed by the
                Company), and are not acting as fiduciaries.  In
                making such verification, the members of the
                Committee appointed by ALPA shall, acting as a
                group, cast a single vote, the members of the
                Committee appointed by the IAM shall, acting as
                a group, cast a single vote, and the member
                appointed by the Company shall cast a single
                vote.  The calculation of the Revised Class 1
                Decimal shall only be considered verified if all
                three of such votes are cast in favor of
                verification.  If the Committee has not verified
                the calculation of the Revised Class 1 Decimal
                determined by the Company by a Measuring Date
                Anniversary, then the Revised Class 1 Decimal
                shall be determined pursuant to the provisions
                of this Agreement other than Section 1.6(e)
                (including Section 1.6(q), which generally
                contemplates that the Company, the IAM and ALPA
                will cooperate to modify the Class 1 Decimal).
                The parties agree that the result of the
                calculations described above for each plan year
                may be a range of values for the Revised Class 1
                Decimal, including but not limited to a value to
                be applicable to each possible Purchase Price.

          The Subsequent Year Release Shares for each such plan
     year shall be released from the ESOP suspense account and
     allocated to the accounts of ESOP participants as of the end
     of such plan year; provided, however, that by the due date
     for each contribution by the Company to be used by the ESOP
     Trustee for loan repayment, the Company shall in
     consultation with its advisers, make a reasonable estimate
     of the maximum contribution which can be made to Part A of
     the ESOP (as defined in the ESOP) consistent with (www)
     satisfaction of the principles set forth in Section 1.6(l),
     (xxx) achieving a high degree of certainty that the limits
     of Internal Revenue Code Section 415(c)(6) shall not be
     exceeded, (yyy) avoiding an allocation of contributions
     which would cause all members of an Employee Group to exceed
     the limits of Internal Revenue Code Section 415(c), and
     (zzz) limiting the purchase of ESOP Preferred so that there
     can be allocated sufficient shares of Supplemental ESOP
     Preferred for each Employee Group to permit appropriate
     allocations in the Supplemental ESOP to individuals whose
     allocations in the ESOP reached the limit of Code Section
     415(c).  The estimate of the Company referred to in the
     preceding sentence shall not be made by reconsidering the
     principles set forth in clauses (www) through (zzz), but
     shall instead be made by using the same methodology which
     was used by the Company (and verified by the Committee) for
     the determination of the Revised Class 1 Decimal, and such
     methodology shall be applied by using such updated data as
     may be reasonably available to the Company prior to the
     determination of the contribution.  The balance of the
     Subsequent Shares for such plan year (the "Subsequent Year
     Remaining Shares") shall be released from the ESOP suspense
     account and allocated to the accounts of ESOP participants
     in level installments for each full plan year (and prorated
     for the quarter ending March 31, 2000) remaining in the
     period from the January 1 immediately following such plan
     year through March 31, 2000.  Notwithstanding the foregoing,
     if (aaa) pursuant to this paragraph, the Company's
     contribution was not sufficient to cause all Subsequent Year
     Release Shares to be released from the ESOP suspense
     account, or (bbb) the Company's contribution caused all
     members of an Employee Group to reach the limit under
     Internal Revenue Code Section 415(c), thus causing the
     creation of a suspense account under Treasury Regulation
     Section 1.415-6(b)(6)(iii), then the Subsequent Year Release
     Shares which were not allocated to the accounts of ESOP
     participants in the year such shares were purchased by the
     ESOP Trustee shall be considered Subsequent Year Remaining
     Shares and shall be allocated in the next following year.

          For each of the third through sixth plan years of the
     Supplemental ESOP, there shall be credited to the accounts
     of Supplemental ESOP participants shares of Supplemental
     ESOP Preferred equal to the remainder of (aa) 12/69ths of
     the Final Number and (bb) the number of shares of ESOP
     Preferred allocated to the accounts of ESOP participants
     that year."
    
          4.  The parties agree that the Company shall adopt the
fourth amendment to the ESOP and the fourth amendment to the
Supplemental ESOP in substantially the form attached hereto as
Exhibits B and C, and ALPA and the IAM hereby approve such
amendments.


          IN WITNESS WHEREOF, the parties have caused this
Agreement to be duly executed by their respective authorized
officers as of this 16th day of July, 1996.

Such advance payment base prices will be used to determine the
amount of the first advance payment to be made by Buyer on each
Aircraft pursuant to the provisions of Article 5.2. The advance
payment base price of each Aircraft has been established using
currently available forecast of the escalation factors used by
Boeing and applicable to the scheduled month and year of Aircraft
delivery.  The advance payment base prices will be further
increased or decreased by Boeing not later than twenty-five (25)
months prior to the scheduled month of delivery, as required to
reflect the effects of the then-current forecasted escalation
factors used by Boeing in accordance with Exhibit D. The advance
payment base price of each Aircraft, including any adjustments
made thereto, as contemplated herein, is referred to as the
"Advance Payment Base Price."

       5.2          Advance Payments.  Buyer shall pay to Boeing
advance payments for each Aircraft on the dates indicated in the
schedule below.  The advance payment amount for an Aircraft due
on a payment date shall be equal to (i) the sum of the advance
payment percentages given in such schedule through the payment
date multiplied by the Advance Payment Base Price for the
Aircraft provided to Buyer pursuant to Article 5.1 for such
payment date, less (ii) the sum of the advance payment amounts
paid by Buyer to Boeing on such Aircraft up to such payment date.

       5.3     Payment for Aircraft.  Concurrently with delivery
of each Aircraft, Buyer shall pay to Boeing the Purchase Price
thereof, less the total amount of advance payments theretofore
received by Boeing for such Aircraft under Article 5.2.

       5.4     Repayment of Advance Payments.  If this Agreement
is terminated with respect to any Aircraft (i) by Buyer under
Article 6.2, (ii) by Buyer under Article 11, or (iii) by failure
of Buyer to provide Boeing with written notice pursuant to
Article 6.4, then Boeing shall promptly repay to Buyer, without
interest, any advance payments received by Boeing from Buyer here

contrast to benchmark adjustments or other corrections of
previously published data) or (ii) discontinues publication of
any of the data referred to above, Pratt & Whitney Aircraft
(P&WA) agrees to meet with Boeing and jointly select a substitute
for the revised or discontinued data, such substitute data to
lead in application to the same adjustment result, insofar as
possible, as would have been achieved by continuing the use of
the original data as it may have fluctuated had it not been
revised or discontinued.  Appropriate revision of the Engine
Price Adjustment provisions set forth above shall be made to
accomplish this result for affected Engines.

In the event the Engine Price Adjustment escalation provisions of
this Agreement are made non-enforceable or otherwise rendered
null and void by any agency of the United States Government, P&WA
agrees to meet with Boeing and jointly agree, to the extent that
they may lawfully do so, to adjust equitably the Purchase Price
of any affected Engine(s) to reflect an allowance for increases
in labor, material and fuel costs that occurred from December,
1994 to the seventh month preceding the month of scheduled
delivery of the applicable Aircraft.

NOTE:  Any rounding of a number, as required under this Exhibit D
       with respect to escalation of the Engine price, shall 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 shall be raised to the next
       higher number.
