(1) This Registration Statement covers the shares of Common Stock, par value
    $0.01 per share, of UAL (the "New Shares") and the shares of either Series
    D Redeemable Preferred Stock of UAL or Series E Redeemable Preferred Stock
    of UAL to be issued in exchange for, and upon conversion of the shares of
    the Common Stock, par value $5 per share, of UAL (the "Old Shares") in
    connection with the Recapitalization. If the Series D Redeemable Preferred
    Stock is issued, immediately upon issuance, the Series D Redeemable
    Preferred Stock will be redeemed for $25.80 in cash, Series A Debentures
    due 2004 of United, Series B Debentures due 2014 of United (collectively,
    the "Debentures") and Depositary Preferred Shares representing shares of
    Series B Preferred Stock of UAL. If the Series E Redeemable Preferred
    Stock is issued, immediately upon issuance it will be redeemed for cash
    equal to $25.80 plus the proceeds of the sale of the Debentures and the
    Depositary Preferred Shares. For the purposes of calculating the
    registration fee pursuant to Rule 457(f)(1), (i) the number of Old Shares
    to be exchanged and converted is 28,926,185 and (ii) $746,295,573 of cash
    ($25.80 per Old Share), which will be paid by UAL in connection with the
    Recapitalization, has been subtracted (pursuant to Rule 457(f)(3)) from
    the aggregate market value of Old Shares to be exchanged and converted in
    the Recapitalization. The aggregate market value of the Old Shares has
    been computed by taking the average of the high and low prices for the Old
    Shares on the New York Stock Exchange, Inc. on April 6, 1994 ($127.125).
        
   
(2) As noted below, the Debentures were registered as Debt Securities of
    United pursuant to the Registration Statement on Form S-3 (No. 33-57192)
    filed on January 21, 1993. Of the aggregate fee calculated pursuant to
    Rule 457(f), $310,208.41 is attributable to the Debentures, and the amount
    of the registration fee has been reduced by such amount. The net
    registration fee was paid upon the original filing.

SHALL BECOME EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID
SECTION 8(A), MAY DETERMINE.
 
  AS PROVIDED UNDER RULE 429, THE DEBENTURES TO BE OFFERED HEREUNDER WERE

                                                               June  , 1994     
 
Dear Stockholder:
   
  At a Meeting of Stockholders of UAL Corporation scheduled to be held at the
      on June  ,1994, common stockholders will be asked to approve a
recapitalization transaction that substantially alters the cost structure of
UAL's principal subsidiary, United Airlines, a change that is intended to
immediately strengthen the carrier's competitive position in worldwide aviation
markets while improving its long-term financial viability well into the future.
    
   
  As part of the transaction, employees will make an investment, which is
estimated by the Company to have a net present value of approximately $4.9
billion, in the form of wage and benefit reductions, work-rule changes and
related savings. In return, through the establishment of Employee Stock
Ownership Plans, participating employees will hold, initially, approximately 55
percent of the equity in the Company with current stockholders, initially,
retaining approximately 45 percent of the equity in the Company, subject to
adjustment in certain circumstances. In addition, current common stockholders
will receive additional consideration in the form of cash, or a combination of
cash, debentures and preferred stock as described below.     
 
  We believe that the transaction directly addresses the major problem facing
United and virtually all mature air carriers in the United States: a high cost
structure that impedes effective competition with newer, low-cost carriers that
have increased significantly their U.S. domestic market share over the past
five years and that are continuing to make significant inroads into United's
traditional markets.
 
  The employee investment is expected to reduce costs substantially throughout
United's worldwide route system. The investment specifically addresses the
critical challenge facing United in U.S. domestic markets by facilitating the
creation of a new operation--an "airline-within-an-airline"--that is intended
to compete more effectively with low-cost carriers in short-haul markets where
they are most predominant.
 
  In addition--and importantly in a service business such as an airline--this
transaction should enhance the commitment of employees by providing a tangible
link between the Company's operating performance and the resulting rewards that
can be realized by employee-owners of the Company.
   
  The transaction will take the form of a recapitalization. At the same time,
United will be making a public offering of its debt securities and the Company
will be making a public offering of depositary shares representing Company
preferred stock. If the offerings are consummated, current common stockholders
will receive an amount of cash equal to the sum of (a) $25.80, (b) the proceeds
(without deducting the underwriting discount or other costs) from the sale by
United of $31.10 face amount of its debt securities and (c) the proceeds
(without deducting the underwriting discount or other costs) from the sale by
the Company of depositary shares representing $31.10 liquidation preference of
preferred stock. If the offerings are not consummated, current common
stockholders will receive (i) $25.80 in cash, (ii) $31.10 face amount of
United's debt securities and (iii) depositary shares representing $31.10
liquidation preference of the Company's preferred stock. Current Common
stockholders also will retain a significant ongoing equity interest in the
Company that will be the same regardless of whether the offerings are
consummated. Under various circumstances, however, the value of the
consideration to be received by common stockholders could be less than the
stated face amount or liquidation preference of the debt securities or
preferred stock interests.     
<PAGE>
 
  The attached Proxy Statement/Joint Prospectus details the proposed
transaction, including the establishment of a revised corporate governance
structure that will be implemented through, among other things, amendments to
the Company's Restated Certificate of Incorporation and Bylaws.
   
  The Board of Directors has approved the recapitalization plan and has
determined that the proposed recapitalization is fair to the holders of the
Company's common stock. The Board of Directors recommends that holders of
common stock vote FOR approval of the recapitalization plan and the related
matters identified as Items 2 through 8 on the enclosed proxy card.

recapitalization contained in the attached Proxy Statement/Joint Prospectus,
including pages 14 through 27 that outline the benefits that the Company
expects to achieve as a result of the employee investment, including the
opinions of the Company's financial advisors, CS First Boston Corporation and
Lazard Freres & Co. The Proxy Statement/Joint Prospectus also describes a
number of other matters to be voted upon by holders of common stock at the
Meeting.

                             UNITED AIR LINES, INC.

  Contemporaneously with this solicitation, United Air Lines, Inc., the
Company's wholly-owned subsidiary ("United"), is offering for sale (the "United
Debt Offering") $382,500,000 principal amount of its Series A Debentures due
2004 (the "Series A Debentures") and $382,500,000 principal amount of its
Series B Debentures due 2014 (the "Series B Debentures" and, together with the
Series A Debentures, the "Debentures") and the Company is offering for sale
(the "UAL Preferred Offering" and, together with the United Debt Offering, the
"Offerings") 30,600,000 depositary shares (the "Depositary Preferred Shares"),
each representing $25.00 interests in liquidation preference of the Series B
Preferred Stock, without par value, of the Company (the "Public Preferred
Stock").     
   
  If the Offerings are consummated, each holder of an Old Share will receive in
connection with the Recapitalization (i) one-half (0.5) of a new share of
common stock, par value $0.01 per share, of the Company (the "New Share") and
(ii) cash in an amount equal to the sum of (a) $25.80, (b) the proceeds
(without deducting the underwriting discount or other costs) from the sale by
United of $15.55 principal amount of Series A Debentures and $15.55 principal
amount of Series B Debentures pursuant to the United Debt Offering and (c) the
proceeds (without deducting the underwriting discount or other costs) from the
sale by the Company of 1.244 Depositary Preferred Shares representing interests
in $31.10 aggregate liquidation preference of its Public Preferred Stock
pursuant to the UAL Preferred Offering. If the Offerings are not consummated,
each holder of an Old Share     
<PAGE>
 
   
will receive in connection with the Recapitalization (i) one half (0.5) of a
New Share, (ii) $25.80 in cash, (iii) $15.55 principal amount of Series A
Debentures, (iv) $15.55 principal amount of Series B Debentures and (v) 1.244
Depositary Preferred Shares representing interests in $31.10 liquidation
preference of Public Preferred Stock. Under various circumstances, however,
the value of the consideration to be received by stockholders could be less
than the stated face amount or liquidation preference of the Debentures or
Depositary Preferred Shares.     
   
  The interest rates on the Debentures and the dividend rate on the Public
Preferred Stock have been set provisionally and are subject to adjustment
prior to the Meeting. See "THE PLAN OF RECAPITALIZATION--Terms and
Conditions--Pricing the Securities."     
       
   
  One-half of a New Share will represent an equity interest (based on "Fully
Diluted Old Shares," as defined in "THE PLAN OF RECAPITALIZATION--Terms and
Conditions") immediately after the Recapitalization of 45% of one Old Share's
current percentage equity interest in the Company, subject to possible
reduction. See "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--
Additional Shares." The funds (other than the proceeds of the Offerings, if
applicable) required to effect the Recapitalization, to pay related expenses
(including certain expenses of ALPA and the IAM) and to provide for the
Company's working capital needs after the Recapitalization are expected to be
provided from the Company's internal resources.     
   
  The Plan of Recapitalization provides for amendments to the Company's
Restated Certificate of Incorporation and Bylaws, which will provide, among
other things, for a restructuring of the entire Board of Directors of the
Company. If the Recapitalization is consummated, these amendments, together
with the ownership initially of at least 55% of the Company's common equity
interests by a trust, the crediting of certain shares for future issuance for
certain of its employees and provisions that will preserve the majority voting
power of the employee groups so long as their percentage economic interest in
the Company remains above certain levels, will have the effect of a change in
control of the Company and may make more difficult a future change in control
of the Company. See "THE PLAN OF RECAPITALIZATION--Revised Governance
Structure."     
 
  IN ASSESSING THE RECAPITALIZATION, EACH STOCKHOLDER SHOULD BE AWARE THAT
CERTAIN FACTORS INVOLVED IN THE RECAPITALIZATION MAY INCREASE THE RISK
ASSOCIATED WITH, AND MAY OTHERWISE ADVERSELY AFFECT THE VALUE OF, MAINTAINING
AN EQUITY INVESTMENT IN THE COMPANY. THESE FACTORS INCLUDE AN IMMEDIATE CHANGE
OF THE COMPANY'S CAPITALIZATION TO ONE THAT IS MORE LEVERAGED. SEE "SPECIAL
FACTORS--CERTAIN RISK FACTORS" AND "--CERTAIN EFFECTS OF THE
RECAPITALIZATION."
   
  Consummation of the Recapitalization is subject to certain conditions,
including approval of the Plan of Recapitalization by holders of at least a
majority of the outstanding Old Shares. See "THE PLAN OF RECAPITALIZATION--
Terms and Conditions." Consummation of the Recapitalization is not conditioned
on, or subject to, consummation of the Offerings, although consummation of the
Offerings is conditioned on, and subject to, consummation of the
Recapitalization. The consummation of each of the United Debt Offering and the
UAL Preferred Offering is conditioned on, and subject to, consummation of the
other.

Algonquin Road, Elk Grove Township, Illinois 60007, its telephone number at
such address is (708) 952-4000 and the mailing address of the Company is P.O.

  Contemporaneously with this solicitation, United is offering for sale (the
"United Debt Offering") $382,500,000 principal amount of Series A Debentures
and $382,500,000 principal amount of Series B Debentures and the Company is

representing interests in $25.00 liquidation preference of the Public Preferred
Stock. If the Offerings are consummated, the proceeds thereof will be used to
fund a portion of the cash payment to be made to holders of Old Shares pursuant
to the Recapitalization. Consummation of each of the United Debt Offering and
the UAL Preferred Offering is conditioned upon consummation of the other. If
the Offerings are consummated, it is expected that they will be consummated at
the Effective Time.     
       
RECORD DATE; STOCKHOLDERS ENTITLED TO VOTE
   
  Only holders of record of Old Shares at the close of business on May 23, 1994
(the "Record Date") will be entitled to notice of, and to vote at, the Meeting
and any adjournment or postponement thereof. Stockholders of record on the
Record Date are entitled to one vote per Old Share held as of that date on any
matter that may properly come before the Meeting. See "INTRODUCTION--Voting
Rights and Proxy Information."     
 
                                       ix
<PAGE>

 
VOTE REQUIRED
   
  Under the Delaware General Corporation Law (the "DGCL"), the affirmative vote
of the holders of a majority of the Old Shares outstanding on the Record Date
will be required in order to approve and adopt the Plan of Recapitalization and
the Charter and Bylaw Amendments, the affirmative vote of the holders of a
plurality of Old Shares present in person or represented by proxy at the
Meeting will be required to elect each of the Public Directors and the
affirmative vote of the holders of a majority of Old Shares present in person
or represented by proxy at the Meeting will be required to approve or adopt
each of the other matters identified in this Proxy Statement/Prospectus as
being presented to holders of Old Shares at the Meeting. None of the votes
described above requires the separate approval of at least a majority of the
Company's unaffiliated stockholders for its adoption. The Company's directors
(other than Dr. Brimmer) and executive officers, and their affiliates, have
sole or shared voting power and beneficial ownership with respect to
approximately 1.6 percent of the outstanding Old Shares which they intend to
vote in favor of the Plan of Recapitalization and the Charter and Bylaw
Amendments. Accordingly, the affirmative vote of the holders of approximately
48.4 percent of the outstanding Old Shares (other than directors and executive
officers and their affiliates) is required for approval of the Plan of
Recapitalization. Dr. Brimmer expects to vote his 450 Old Shares against the
Plan of Recapitalization and the Charter and Bylaw Amendments. See
"INTRODUCTION--Voting Rights and Proxy Information."     
 
THE PLAN OF RECAPITALIZATION
 
  The Plan of Recapitalization provides for the following transactions (the
"Recapitalization"):
   
  (i) Reclassification--Upon the Effective Time, each outstanding Old Share,
including each share of restricted stock issued pursuant to the Company's 1988
Restricted Stock Plan, together with up to 1,000,000 Old Shares held by the
Company as treasury stock or owned by any wholly-owned subsidiary of the
Company, will be reclassified as, and converted into, one-half (0.5) of a New
Share and     
     
    (a) if the Offerings are consummated, one one-thousandth of a share of
  Series E Redeemable Preferred Stock, without par value, of the Company (the
  "Series E Redeemable Preferred Stock"), which one one-thousandth of a share
  will be redeemed immediately after issuance, for an amount of cash equal to
  the sum of (i) $25.80, (ii) the proceeds (without deducting the
  underwriting discount or other costs) from the sale by United of $15.55
  face amount of Series A Debentures and $15.55 face amount of Series B
  Debentures and (iii) the proceeds (without deducting the underwriting
  discount or other costs) from the sale by the Company of 1.244 Depositary
  Preferred Shares representing interests in $31.10 liquidation preference of
  Public Preferred Stock or     
     
    (b) if the Offerings are not consummated, one one-thousandth of a share
  of Series D Redeemable Preferred Stock, without par value, of the Company
  (the "Series D Redeemable Preferred Stock" and, together with the Series E
  Redeemable Preferred Stock, the "Redeemable Preferred Stock"), which one
  one-thousandth of a share will be redeemed immediately after issuance for
  (i) $25.80 in cash, (ii) $15.55 face amount of Series A Debentures, (iii)
  $15.55 face amount of Series B Debentures and (iv) 1.244 Depositary
  Preferred Shares representing interests in $31.10 liquidation preference of
  Public Preferred Stock.     
   
One-half of a New Share will represent an equity interest (based on Fully
Diluted Old Shares) immediately after consummation of the Recapitalization of
45% of one Old Share's current percentage equity interest in the Company,
although, under certain circumstances that percentage may be reduced to a
minimum of approximately 37%. See "THE PLAN OF RECAPITALIZATION--Establishment
of ESOPs--Additional Shares." The interest rate on the Series A Debentures has
been fixed provisionally at 9.00%, the interest rate on the Series B Debentures
has been fixed provisionally at 9.70% and the dividend rate on the Public
Preferred Stock has been fixed provisionally at 10.25%. The interest rates on
the Debentures and the dividend rate on the Public Preferred Stock will be
adjusted not less than five nor more than ten days before the date of the
Meeting (the "Announcement Date") to rates (which, in each case, if there is an
upward adjustment, may not be more than 112.5 basis points (i.e., 1.125
percentage points) higher than the respective provisional     
 
                                       x
<PAGE>
 
   
rates, but which in the case of a downward adjustment are not limited) that, in
the opinion of the certain financial advisors to the Company and the Unions (as
defined below) and, in the case of a deadlock, based on a process involving a
third financial advisor, would permit the Debentures and the Public Preferred
Stock to trade at par on such date on a fully distributed basis. See "THE PLAN
OF RECAPITALIZATION--Terms and Conditions--Pricing the Securities."     
   
  The underwriting agreements relating to the Offerings will provide that if
the Offerings are consummated, the interest rates on the Debentures and the
dividend rate on the Public Preferred Stock represented by Depositary Preferred
Shares may be adjusted to permit them to be sold at or closer to par, but if
that is done, the principal amount of the series of Debentures affected or the
number of Depositary Preferred Shares representing interests in the Public
Preferred Stock, as the case may be, will be reduced so that the aggregate
amount of interest payable annually by United on the Debentures or the
aggregate amount of dividends payable annually by the Company on the Public
Preferred Stock will not exceed certain maximum amounts calculated with
reference to such caps. If the Offerings are not consummated, the interest
rates borne by the Debentures and the dividend rate borne by the Public
Preferred Stock will be subject to the caps. See "THE PLAN OF
RECAPITALIZATION--Terms and Conditions--Pricing the Securities."     
   
  On the Announcement Date, the Company will issue a press release setting
forth the adjusted rate for the Debentures and the Public Preferred Stock and,
on the first business day following the Announcement Date, will publish such
rates in an advertisement in The Wall Street Journal. A toll-free number (800-
223-2064) has been established from which all holders of Old Shares can obtain
general recorded information concerning the Announcement Date. As of the
Announcement Date, holders of the Old Shares can call the toll-free number to
obtain definitive pricing information. See also "SPECIAL FACTORS--Certain Risk
Factors--Pricing of Public Preferred Stock and Debentures."     
   
  The press release, newspaper advertisement and recorded information following
the Announcement Date described in the previous paragraph will include a
statement of whether the Company expects the Offerings to be consummated and,
if so, the amount of the cash proceeds expected to be received from the sale of
the Debentures and Depositary Preferred Shares that are issuable in respect of
each Old Share. ANY STATEMENT IN CONNECTION WITH THE FOREGOING THAT THE COMPANY
EXPECTS THE OFFERINGS TO BE CONSUMMATED WILL NOT BE AN ASSURANCE THAT THE
OFFERINGS WILL BE CONSUMMATED.     
       
  (ii) Charter and Bylaw Amendments--The Plan of Recapitalization provides for
the Charter and Bylaw Amendments that will, among other things, effectuate the
Recapitalization and put into place the revised corporate governance structure
contemplated by the Plan of Recapitalization. See "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure."
   
  (iii) The Stock Issuance--Pursuant to the Plan of Recapitalization, the
Company will issue, in addition to the securities issued as part of the
Recapitalization Consideration, (a) the Class 1 ESOP Convertible Preferred
Stock to the trustee (the "ESOP Trustee") and the Class 2 ESOP Convertible
Preferred Stock (or the common shares into which they are convertible) to the
ESOP Trustee or for the benefit of employees (collectively, the "ESOP Preferred
Stock") pursuant to the ESOPs that will be established for the benefit of the
employee groups that will be making wage, salary and work-rule changes in
connection with the Plan of Recapitalization (the Class 1 and Class 2 ESOP
Convertible Preferred Stock are referred to collectively as the "ESOP Preferred
Stock"), (b) the Class P ESOP Voting Junior Preferred Stock (the "Class P
Voting Preferred Stock"), the Class M ESOP Junior Voting Preferred Stock (the
"Class M Voting Preferred Stock") and the Class S ESOP Voting Junior Preferred
Stock (the "Class S Voting Preferred Stock" and, together with the Class P
Voting Preferred Stock and the Class M Voting Preferred Stock, the "Voting
Preferred Stock") to the ESOP Trustee, (c) the Class I Junior Preferred Stock
(the "Class I Preferred Stock") to the initial independent directors who will
enter into a stockholders' agreement to vote their shares to elect the     
 
                                       xi
<PAGE>
 
   
future independent directors to the Board, (d) one share of the Class Pilot MEC
Junior Preferred Stock (the "Class Pilot MEC Preferred Stock") to the United
Airlines Pilots Master Executive Council (the "ALPA-MEC") of the Air Line Pilots
Association, International ("ALPA"), which will have the right to elect a 
director to the Board (the "ALPA Director"), (e) one share of the Class IAM
Junior Preferred Stock (the "Class IAM Preferred Stock") to the International
Association of Machinists and Aerospace Workers (the "IAM" and, together with
ALPA, the "Unions"), or its designee, which will have the right to elect a
director to the Board (the "IAM Director" and together with the ALPA Director,
the "Union Directors") and (f) two shares of Class SAM Junior Preferred Stock
(the "Class SAM Preferred Stock" and, together with the Class I Preferred
Stock, the Class Pilot MEC Preferred Stock and the Class IAM Preferred Stock,
the "Director Preferred Stock") to the person nominated to serve as the
salaried and management employees' director (the "Salaried and Management
Director" and, together with the Union Directors, the "Employee Directors" )
and one share to an additional designated stockholder, which will have the
right to vote as a class to elect a director to the Board. See "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs," "--Revised Governance Structure" and
"DESCRIPTION OF SECURITIES." The ESOP Preferred Stock is nonvoting. The Voting
Preferred Stock was established in order to allocate voting power to the
respective employee groups in proportion to the agreed upon allocation and in a
manner which was consistent with applicable law. The ESOP Preferred Stock and
the Voting Preferred Stock will initially represent a 55% equity interest
(based on Fully Diluted Old Shares), including voting interest on all matters
presented to holders of New Shares other than the election of Public Directors
(as defined below), immediately after consummation of the Recapitalization,
although under certain conditions the percentage may be increased to up to a
maximum of approximately 63%. See "THE PLAN OF RECAPITALIZATION--Establishment
of ESOPs--Additional Shares." The holders of the Voting Preferred Stock will
continue to command the same adjusted percentage of voting power (if and as so
adjusted) of the Company following the Recapitalization until the economic
interest represented by the stock held in Company sponsored benefit and
retirement plans (including stock to be issued in the future under the ESOPs)
becomes less than 20% of the common equity of the Company calculated as
described under "THE PLAN OF RECAPITALIZATION--Revised Governance Structure--
Sunset."     
       
       
       
   
  (iv) Employee Investment--Certain amendments to the existing ALPA collective
bargaining agreement and the IAM collective bargaining agreements, and creation
of a salaried and management employees cost reduction program, all of which
will become effective at the Effective Time, are estimated to provide United
with approximately $8.2 billion in improved operating earnings over a twelve-
year period, which earnings are expected to have a net present value of
approximately $4.9 billion. Approximately $5.2 billion of such improvement is
expected to arise from savings in labor costs, while the remaining
approximately $3.0 billion is expected to arise from the startup of a new
short-haul "airline-within-an-airline" referred to herein as "U2", which is
expected to compete effectively against other low-cost, short-haul carriers.
See "SPECIAL FACTORS--Certain Company Analyses," and "--Implementation of the
"Airline-Within-an-Airline' (U2)."     
   
  (v) Employee Benefit Plans--Certain employee benefit plans maintained by the
Company and United will be amended to permit employees to acquire substantial
amounts of the New Shares, Depositary Preferred Shares and the Debentures. See
"THE PLAN OF RECAPITALIZATION--Terms and Conditions--Certain Covenants."     
 
 Effective Time of the Recapitalization
   
  The Recapitalization will be consummated at such time as the Company's
amended and restated Certificate of Incorporation (the "Restated Certificate"),
which provides for the reclassification of the Old Shares, is duly filed with
the Secretary of State of the State of Delaware or at such later time as may be
mutually agreed upon by the Company and each of the Unions and as is specified
in the Restated Certificate (the "Effective Time"). The filing of the Restated
Certificate is currently anticipated to be made as promptly as practicable
after the Meeting. Such filing will be made, however, only upon satisfaction
or, where     
 
                                      xii
<PAGE>
 
   
permissible, waiver of all conditions contained in the Plan of Recapitalization
and provided that the Plan of Recapitalization has not been terminated. See
"THE PLAN OF RECAPITALIZATION--Terms and Conditions--Termination." If the
Offerings are consummated, it is expected that they will be consummated at the
Effective Time.     
 
 Conditions to the Recapitalization
   
  Pursuant to the Plan of Recapitalization, the obligation of the Company to
file the Restated Certificate at the Effective Time and the obligations of each
of the Unions to enter into the revised collective bargaining agreements at the
Effective Time are subject to the satisfaction of the following conditions,
among others: (i) holders of Old Shares have approved and adopted the Plan of
Recapitalization and related transactions, as identified in "INTRODUCTION--
Purpose of the Meeting," (ii) all material actions by or in respect of or
filings with any governmental body, agency, official, or authority required to
permit the consummation of the Recapitalization have been taken or made, (iii)

Effective Time, the acquisition of the Class 1 ESOP Preferred Stock by the ESOP
Trustee is fair, from a financial point of view, to the ESOP participants, (v)
the Board has received an updated solvency opinion from American Appraisal
Associates, Inc. ("American Appraisal"), (vi) all the agreements required to be
executed and delivered at the Effective Time are legal, valid and binding
agreements of the Company and the other parties thereto from and after the
Effective Time, enforceable against the Company and such other parties in
accordance with their terms, including the stock purchase agreement pursuant to
which the ESOP Trustee will purchase Class 1 ESOP Preferred Stock at the
Effective Time, (vii) Mr. Gerald M. Greenwald (or such other person as proposed
by the Unions prior to the Effective Time and not found unacceptable by the
Company) is ready, willing and able to assume the office of Chief Executive
Officer ("CEO") of the Company and United, (viii) the Board has received
updated written opinions of each of CS First Boston Corporation ("CS First
Boston") and Lazard Freres & Co. ("Lazard") confirming their earlier opinions,
to the effect that the Recapitalization Consideration, taken as a whole, is
fair from a financial point of view to the holders of Old Shares, (ix) the
revised collective bargaining agreements have been executed and delivered by
the Unions and United and will be in full force and effect as of the Effective
Time, (x) the Board has received satisfactory opinions of counsel and (xi) the
Company has determined that the Company will be reasonably likely to have
sufficient surplus (whether revaluation surplus or earned surplus) or net
profits under the Delaware General Corporation Law (the "DGCL") to permit the
legal payment of dividends on the ESOP Preferred Stock and the Public Preferred
Stock when due. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--
Conditions." The Recapitalization is not conditioned upon the consummation of
either the United Debt Offering or the UAL Preferred Offering.     
 
 Payment for Old Shares
   
  To receive the Recapitalization Consideration, each holder of Old Shares must
surrender his certificates representing Old Shares, together with a duly
executed letter of transmittal, to First Chicago Trust Company of New York (the
"Exchange Agent"). Instructions regarding the surrender of certificates,
together with a form of transmittal letter to be used for this purpose, will be
forwarded to stockholders promptly after the Effective Time. STOCKHOLDERS
SHOULD NOT FORWARD CERTIFICATES WITH THE ENCLOSED PROXY CARD. STOCKHOLDERS
SHOULD SURRENDER CERTIFICATES ONLY AFTER RECEIVING INSTRUCTIONS FROM THE
EXCHANGE AGENT. In lieu of any fractional interests of New Shares and, if the
Offerings are not consummated, Debentures or Depositary Preferred Shares that
each former holder of Old Shares would otherwise be entitled to receive, the
Exchange Agent will make a pro rata distribution of the cash proceeds received
by the Exchange Agent from the sale of the aggregate fractional interests of
New Shares and, if the Offerings are not consummated, Debentures and Depositary
Preferred Shares. No interest will be paid or accrued in favor of any
stockholder on the     
 
                                      xiii
<PAGE>
 
   
amounts payable upon surrender of certificates. Each stockholder will be
responsible for the payment of transfer and other taxes, if any. See "THE PLAN
OF RECAPITALIZATION--Terms and Conditions--Payment for Shares."     
 
 Background of the Recapitalization
 
  Since the mid 1980s, in response to enhanced competition from low-cost air
carriers resulting from the industry's deregulation and discordant relations
between the Company and its principal unions, ALPA, the IAM and the Association
of Flight Attendants ("AFA"), several attempts to effect a potential change in
corporate control or the sale of substantial assets of the Company have
occurred or were proposed, many of which involved the participation of one or
more of the Company's unions.
 
  In recent years, including during 1992, the Company has noted a fundamental
shift in consumer behavior, with an increased focus on the price/value
relationship. Travel preference has continued to shift to low-cost travel as
provided by carriers such as Southwest Airlines, Morris Air and Reno Air. The
Company believed that this trend was long-term and would continue even if the
weak economic conditions of the early 1990s improved. The Company determined
that its ability to be competitive in such an environment required a
substantial reduction of its operating costs.
 
  Thus, on January 6, 1993, the Company announced a $400 million cost reduction
program, including the sub-contracting of certain services and the furlough of
2,800 employees. It also significantly reduced its aircraft purchase
commitments through 1996, with a net effect of reducing the Company's planned
capital spending through 1996 by over $6.2 billion. The Company determined that
it was necessary to reduce its single largest expense, labor costs, to be
competitive in the changed environment of the 1990s. Thus, in addition to the
subcontracting, furloughs and the implementation of a 5% salary reduction
program for certain management employees, the Company requested concessions
from its three principal unions. However, this request was rejected by the IAM
and the AFA, and ALPA requested a financial review of the Company. In light of
the unwillingness of the Unions to participate in the Company's cost-cutting
efforts, the Company thereafter announced its intention to undertake various
other cost-cutting actions, including selling its flight kitchens and
subcontracting certain ground services, opening a flight attendant domicile in
Taiwan, and evaluating the sale of the Denver flight training center. The
Company also discussed the possibility of selling its jet engine over-haul
maintenance facility in San Francisco, subcontracting its components business,
subcontracting its ground equipment over-haul business and subcontracting its
line maintenance work, building maintenance work and computer terminal
technician work.
   
  In reports presented to the Board of Directors by Booz . Allen & Hamilton
("BAH"), BAH advised the Board that it seemed unlikely that carriers such as
United could achieve sufficient cost reductions without a major restructuring.
The report also suggested that subcontracting jet engine repair could result in
substantial cost savings. In a presentation to the Board on June 24, 1993, BAH
indicated that, in the absence of labor cooperation, the Company had four
options: (i) restructure and downsize to focus on those markets where United
could be profitable in the long term, (ii) restructure and grow to create a
stronger domestic and international competitive position, (iii) return value to
stockholders by monetizing flying assets, services and/or other hard assets and
(iv) sell the airline in whole or in parts. On August 5, 1993, the Board
considered a presentation by BAH and members of Company's management concerning
ways to improve the Company's profitability and provide additional shareholder
value, with specific focus on establishment of one or more domestic short-haul
carriers which would be owned independently of the Company and United and which
would virtually eliminate short-haul flying by United, along with other
fundamental alterations of the Company's business and structure (the
"Fundamental Restructuring Plan").     
 
  As a result of considering the various alternatives presented to the Board
over the past several years and realizing that, in order to achieve a long term
cost reduction program, the employees of the Company must
 
                                      xiv
<PAGE>
 
be involved in any major restructuring of the Company, the Company's management
concluded that long term stockholder value would be maximized through the
proposed Recapitalization.
   
  Since the spring of 1993, the Company has been engaged in extensive
discussions and negotiations with ALPA, the IAM and the AFA with respect to a
"shared solution" that would enable the Company to reduce costs and allow
certain employee groups to gain significant ownership of the Company. In
September of 1993, the AFA ceased to participate in the negotiations, which
continued with ALPA and the IAM (the "Coalition"). On December 22, 1993, an
agreement in principle was reached among the Company, ALPA and the IAM pursuant
to which (i) employee trusts would acquire approximately 53% of the common
equity and voting power of the Company, subject to increase to up to
approximately 63% based on stock price performance in the year after closing,
(ii) holders of Old Shares would receive cash, debt securities, preferred stock
and common stock, (iii) participating employees of the Company would provide
wage and benefit reductions and various work-rule changes and (iv) a new
corporate governance structure would be implemented. A definitive agreement was
signed on March 25, 1994 (the "Initial Plan of Recapitalization") reflecting
the terms of the agreement in principle.     
   
  In light of prevailing market prices for the Old Shares in May 1994 and in
view of such provisions in the Initial Plan of Recapitalization which enabled
the Coalition to assert that pricing conditions to consummation of the
Recapitalization relating to the purchase of the ESOP Preferred Stock would not
be satisfied, the Coalition determined to approach the Company over possible
adjustments to the financial terms of the transaction in order to provide
greater certainty of completion of the Recapitalization. At the same time, the
Company felt that the Offerings would benefit the Company's stockholders as
part of the Recapitalization. In response to a proposal to modify the
definitive documentation from the Coalition, on May 20, 1994 the Board
determined to make an alternative proposal to the Coalition. The Coalition
accepted the Company's alternative proposal on May 22, 1994. On May  , 1994 the
Company and the Coalition executed an amendment to the definitive documentation
(the "Definitive Documentation Amendment") providing for, among other things,
(i) an increase in the percent of the common equity and voting power initially
to be acquired by the employee trusts from 53% to 55%; (ii) a decrease in the
range of average stock prices for the one year following the Effective Time
which would result in an increase to up to 63% in the percent of common equity
and voting power to be received by the employee trusts (prior to the Definitive
Documentation Amendment, the range had been $170.00 - $178.44 per share and it
was decreased to $136.00 - $149.10 per share (giving effect to the 1 for 2
common stock exchange ratio)) (see "THE PLAN OF RECAPITALIZATION--Terms and
Conditions--Additional Shares"); (iii) the inclusion of the Offerings, and (iv)
revisions to the manner in which the Class 1 ESOP Preferred Stock will be
purchased by the ESOP Trustee (see "THE PLAN OF RECAPITALIZATION--Establishment
of ESOPs"). As a result of the Definitive Documentation Amendment, the purchase
of the ESOP Preferred Stock to occur at the Effective Time will be determined
using a market price-based formula and, accordingly, the Coalition is not
entitled to assert that the Recapitalization may not be consummated based on
the market price of the Old Shares or the expected market price of the New
Shares. See "BACKGROUND OF THE PLAN OF RECAPITALIZATION."     
       
   
  Amendments to the collective bargaining agreements with ALPA and the IAM, to
be entered into upon consummation of the Plan of Recapitalization, and a
salaried and management employee cost reduction program, to be established upon
consummation of the Plan of Recapitalization, are estimated to provide United
with approximately $8.2 billion of improved operating earnings over a twelve
year period, which earnings are estimated to have a net present value of
approximately $4.9 billion. Approximately $5.2 billion of such improvement is
expected to arise from savings in labor costs, while the remaining
approximately $3.0 billion is expected to arise from earnings of a new short-
haul "airline-within-an-airline," referred to herein as "U2," which is expected
to compete effectively with low-cost short-haul carriers.

 Recommendation of the Board
 
  THE BOARD HAS APPROVED THE PLAN OF RECAPITALIZATION AND HAS DETERMINED THAT
THE RECAPITALIZATION IS FAIR TO THE HOLDERS OF OLD SHARES. THE BOARD RECOMMENDS
THAT STOCKHOLDERS VOTE FOR THE PLAN OF RECAPITALIZATION AND THE RELATED MATTERS
IDENTIFIED IN CLAUSES (II) THROUGH (VII) UNDER "PURPOSE OF THE MEETING" ABOVE.
   
  The Board noted that the Recapitalization permits the holders of Old Shares
to receive in exchange for each Old Share either (i) cash in an amount equal to
the sum of (a) $25.80, (b) the proceeds (without deducting the underwriting
discount or other costs) from the sale by United of $15.55 principal amount of
Series A Debentures and $15.55 principal amount of Series B Debentures pursuant
to the United Debt Offering and (c) the proceeds (without deducting the
underwriting discount or other costs) from the sale by the Company of 1.244
Depositary Preferred Shares representing interests in $31.10 liquidation
preference of Public Preferred Stock pursuant to the UAL Preferred Offering or
(ii) (a) $25.80 in cash, (b) $31.10 in principal amount of Debentures and (c)
Depositary Preferred Shares representing interests of $31.10 in liquidation
preference of Public Preferred Stock, while in either case retaining a
significant ongoing equity interest in the Company, which would not differ
under clause (i) or (ii). Under various circumstances, the value of the
consideration to be received by stockholders could be less than the stated face
amount or liquidation preference of the Debentures or Depositary Preferred
Shares. In approving the Plan of Recapitalization, the Board also considered
that the majority equity position of the employee stock ownership trusts is
designed to provide additional incentives for the Company's employees to
promote the success of the Company, which should, in part, inure to the benefit
of the holders of shares of Common Stock of the Company. All directors, other
than Dr. Brimmer, voted in favor of the Plan of Recapitalization (prior to the
Definitive Documentation Amendment). Dr. Brimmer has indicated that he
dissented from such vote because under current economic conditions, he did not
think there were compelling reasons to do such a transaction at this time. With
respect to the Definitive Documentation Amendment, the Board voted in favor of
the Definitive Documentation Amendment, with Dr. Brimmer abstaining. It was
mentioned at the meeting that Mr. Olson, who was not in attendance, had
requested that his opposition to the Definitive Documentation Amendment be
noted.     
   
  In reaching its decision to approve the Initial Plan of Recapitalization and
the Plan of Recapitalization, its determination that the Recapitalization is
fair to the holders of Old Shares and its decision to recommend that the
holders of Old Shares vote for approval and adoption of the Initial Plan of
Recapitalization and the Plan of Recapitalization and related matters, the
Board consulted with its legal and financial advisors as well as the Company's
management, and considered numerous factors, including, but not limited to: (i)
the business, operations, earnings, properties and prospects of the Company and
United and the perceived need for the Company to obtain a reduction of wages
and benefits and work-rule changes in order to permit United to compete
effectively in the aviation marketplace, (ii) the alternatives potentially
available to the Company to achieve a reduction of wages and benefits and work-
rule changes, as well as a comparison of the risks that would be associated
with the Recapitalization and with such other alternatives, (iii) the terms of
the employee investment contemplated by the Initial Plan of Recapitalization
and Plan of Recapitalization, including the reduction in cost expense, the
favorable tax treatment of ESOP transactions, the long-term labor contracts
which limit salary increases and the ability to establish U2, (iv) the fact
that the Recapitalization will provide the holders of Old Shares with an
opportunity to receive cash, and, if the Offerings are not consummated,
Debentures and Depositary Preferred Shares representing interests in Public
Preferred Stock for a portion of the value of their Old Shares while retaining
a significant ongoing equity interest in the Company through ownership of New
Shares, (v) the terms of the proposed corporate governance structure, which
contains both certain provisions required by the Coalition and certain
provisions designed for the protection of the holders of New Shares, (vi) the
identity of the new CEO and the new Board (especially the initial Independent
Directors (as defined below)), and the Board's assessment of such individuals,
(vii) recent market prices for the Old Shares as well as market prices for the
past several years, (viii) the Federal income tax consequences     
 
                                      xvi
<PAGE>
 
   
of the Recapitalization under existing law, (ix) (with respect to the Plan of
Recapitalization) the terms of the Definitive Documentation Amendment providing
for an increase in the percentage common equity and voting power initially to
be acquired by the employee trusts and a decrease in the range of average stock
prices determined one year after the Effective Time which would result in an
increase in the percent of common equity and voting power to be held by the
employee trusts, (x) (with respect to the Plan of Recapitalization) the terms
of the Definitive Documentation Amendment providing for the Offerings and the
resulting potential to distribute cash, instead of Debentures and Depositary
Preferred Shares, to holders of Old Shares if the Offerings are consummated,
(xi) (with respect to the Plan of Recapitalization) the use of a market price-
based formula for the purchase of the ESOP Preferred Stock to be purchased at
the Effective Time, and (xii) the opinions of CS First Boston, a nationally
recognized investment banking firm, and the opinions of Lazard, another
nationally recognized investment banking firm, that, based upon the matters
described therein, as of the date of each such opinion, the consideration to be
received by the holders of Old Shares pursuant to the Recapitalization for each
Old Share, taken as a whole, is fair to such stockholders from a financial
point of view. See "SPECIAL FACTORS--Opinions of the Financial Advisors to the
Board," "--Certain Risk Factors" and "--Certain Revenue and Earnings
Scenarios," "THE PLAN OF RECAPITALIZATION" and "MARKET PRICES OF THE SHARES;
DIVIDENDS." The Board also considered (i) the fact that the repayment of the
Debentures and the payment of dividends on the Public Preferred Stock will be
dependent on the Company's operations, assets, credit, cash flow and earning
power, (ii) that, as a result of the Recapitalization, there will be a
significant increase in the Company's long-term indebtedness, as well as a
substantial negative balance in stockholders' equity and a significant
reduction in cash reserves and (iii) the opinion of American Appraisal with
respect to certain solvency and surplus matters. See "SPECIAL FACTORS--Certain
Risk Factors," "THE PLAN OF RECAPITALIZATION" and "UNAUDITED PRO FORMA
FINANCIAL INFORMATION."     
 
  In view of the circumstances and the wide variety of factors considered in
connection with this evaluation of the Recapitalization, the Board did not find
it practicable to assign relative weights to the factors considered in reaching
its decision.
 
 Opinions of the Financial Advisors to the Board
   
   On July 20, 1993, the Company retained CS First Boston to assist it in
evaluating the Coalition proposals. By letter dated November 30, 1993, the
Company retained Lazard as an additional financial advisor. On December 22,
1993, March 14, 1994, March 24, 1994 and May 20, 1994, CS First Boston and
Lazard delivered to the Board their oral opinions (which in the case of the
December 22, 1993, March 24, 1994 and May 20, 1994 opinions were later
confirmed to the Board by CS First Boston and Lazard in writing) that, as of
such dates, the consideration to be received by holders of Old Shares of the
Company in connection with the Recapitalization (as constituted as of each such
date), taken as a whole, was fair to such holders of Old Shares from a
financial point of view. For further details concerning the engagement of CS
First Boston and Lazard, including fees payable to them, see "SPECIAL FACTORS--
Opinions of the Financial Advisors to the Board."     
   
  THE FULL TEXT OF THE WRITTEN OPINIONS OF CS FIRST BOSTON AND LAZARD, EACH
DATED JUNE  , 1994, THAT SET FORTH THE ASSUMPTIONS MADE, THE MATTERS CONSIDERED
AND THE REVIEW UNDERTAKEN WITH REGARD TO EACH SUCH OPINION, ARE ATTACHED AS
ANNEXES I AND II RESPECTIVELY TO THIS PROXY STATEMENT/PROSPECTUS. STOCKHOLDERS
ARE URGED TO READ SUCH OPINIONS IN THEIR ENTIRETY FOR A DESCRIPTION OF THE
PROCEDURES FOLLOWED, MATTERS CONSIDERED, ASSUMPTIONS MADE AND LIMITATIONS ON
THE REVIEW UNDERTAKEN BY SUCH FIRMS. THE OPINIONS ARE DIRECTED ONLY TO THE
FAIRNESS OF THE CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF OLD SHARES AND
DO NOT CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF OLD SHARES AS TO HOW SUCH
HOLDER OF OLD SHARES SHOULD VOTE.     
 
 Interests of Certain Persons in the Recapitalization
 
  In considering the Plan of Recapitalization, stockholders should be aware
that the executive officers and the Board members have certain interests that
present them with potential conflicts of interest in connection
 
                                      xvii
<PAGE>
 
with the Recapitalization. The Board was aware of these potential conflicts and
considered them among the other matters described under "SPECIAL FACTORS--
Recommendation of the Board." See "SPECIAL FACTORS--Interests of Certain
Persons in the Recapitalization."
 
 Certain Risk Factors
   
  In addition to the other information contained in this Proxy
Statement/Prospectus, holders of Old Shares should carefully consider the
following risk factors concerning the New Shares, the Debentures and the
Depositary Preferred Shares representing interests in the Public Preferred
Stock.     
   
  Financial Effects; Delaware Law Considerations. The Recapitalization will
immediately change the Company's capitalization to one that is more highly
leveraged. In this regard, the following discussion compares the pro forma book
effect of the Recapitalization on long-term debt, stockholder's equity and
income/loss from continuing operations with recent historical financial
information of the Company. On a pro forma book basis at March 31, 1994, the
Company would have had approximately $3.451 billion of long-term debt and a
deficit of approximately $448 million of stockholders' equity, as compared to
the approximately $2.693 billion of long-term debt and approximately $1.097
billion of stockholders' equity that was shown on the Company's balance sheet
on such date. In addition, if the Recapitalization had occurred as of January
1, 1993, the Company would have reported, on a pro forma basis, income from
continuing operations of approximately $38 million for the year ended December
31, 1993 and a loss from continuing operations of approximately $58 million for
the three months ended March 31, 1994, as compared to losses from continuing
operations of $31 million for the year ended December 31, 1993 and $71 million
for the three months ended March 31, 1994 that were reported for each period.
See "UNAUDITED PRO FORMA FINANCIAL INFORMATION."     
       
   
  The Company's earnings were inadequate to cover fixed charges and preferred
stock dividends by $98 million in 1993, by $748 million in 1992 and by $599
million in 1991. On a pro forma basis, the Company's earnings in 1993 were
inadequate to cover fixed charges and preferred stock dividends by $109
million. In addition, the Company's ratio of earnings to fixed charges was
inadequate to cover fixed charges and preferred stock dividends for the three
month period ended March 31, 1994 by $118 million, and on a pro forma basis
they were inadequate by $97 million. United's earnings were inadequate to cover
fixed charges by $77 million in 1993, by $694 million in 1992 and by $604
million in 1991. On a pro forma basis, United's earnings in 1993 were
inadequate to cover fixed charges by $63 million. In addition, United's
earnings were inadequate to cover fixed charges for the three month period
ended March 31, 1994 by $130 million, and on a pro forma basis they were
inadequate by $102 million. Non-cash depreciation and amortization are deducted
in computing earnings before fixed charges. Such non-cash charges do not
significantly affect the ability of United to fund operations, service debt, or
provide funds to service the Company's preferred stock dividends. Depreciation
and amortization of United were $722 million in 1993, $695 million in 1992,
$604 million in 1991 and $178 million for the three month period ended March
31, 1994.     
   
  The DGCL requires that the payments to be made to the holders of Old Shares
in the Recapitalization be made from "surplus." For purposes of the DGCL,
surplus equals the excess, if any, at any given time, of the net assets of the
corporation over stated capital. In addition, such payments would not be
permitted if after giving effect to them the Company would not be able to pay
its debts as they become due in the usual course of business. The Board
believes that the Company will be able to pay such debts, based in part on the
revenue and earnings scenarios set forth below under "SPECIAL FACTORS--Certain
Revenue and Earnings Scenarios" and on American Appraisal's opinion referred to
below. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions," and "UNAUDITED
PRO FORMA FINANCIAL INFORMATION." Given the more leveraged financial structure
of the Company following the Recapitalization, certain airline industry risks
could have a greater adverse impact on the Company after the Recapitalization
than prior to the Recapitalization.

  Governance Structure; Ability of Holders of Voting Preferred Stock to
Exercise More than 50% of the Voting Power of the Company. Although the Company
has attempted to achieve a balanced approach to its corporate governance
structure after the Recapitalization, such structure is very unusual in the
management of a large, complex public corporation, and it is not certain that
the actual operation of the corporate governance process will not result in
disputes or fail to achieve results that are in the best interests of the
Company or the holders of New Shares.     
   
  Under the terms of the Restated Certificate, the participants in the ESOPs
(and in certain circumstances the ALPA-MEC, the IAM and the Salaried and
Management Director) will hold and will be entitled to exercise approximately
55% (which under certain circumstances may be increased to up to approximately
63%) of the voting power of the Company until the common equity held by (or
credited to) the ESOPs and other employee benefit plans sponsored by the
Company is less than 20% of the common equity of the Company, all as more fully
described in "THE PLAN OF RECAPITALIZATION--Revised Governance Structure--
Nondilution" and "DESCRIPTION OF SECURITIES--The Voting Preferred Stock." The
termination of the right to exercise 55% or more of the voting power of the
Company is referred to herein as the "Sunset." See "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Sunset." Under current
actuarial assumptions, the Company estimates that this Sunset provision will
not become operative until 2016 if additional purchases are not made by
eligible employee benefit plans. However, such plans will have the right, and
may be expected, to make additional purchases, thereby delaying the occurrence
of the Sunset. In addition, the Restated Certificate contains provisions which
may prevent the Company prior to the Sunset from taking certain specified
actions without the consent of one or both of the members of the Board elected
by ALPA and the IAM or a 75% vote of holders of New Shares and Voting Preferred
Stock. See "THE PLAN OF RECAPITALIZATION--Revised Governance Structure."     
   
  Currently, the Board is comprised of thirteen members elected annually by
holders of the Old Shares. While the existing Board may in its deliberations
consider the interests of employee groups, there is no direct representation on
the Board of specific employee groups. As more fully described below (see "THE
PLAN OF RECAPITALIZATION--Revised Governance Structure"), the Plan of
Recapitalization contemplates that directors elected by representatives of the
employee groups will participate in the governance of the Company. Following
consummation of the Recapitalization and until the Sunset, the Board will
consist of twelve members, comprised of (i) five public directors elected by
holders of the New Shares, who will include (a) three members of the existing
Board or other individuals with no previous material contact with the Company
other than as directors (the "Outside Public Directors") and (b) two
substantially full-time employees of the Company who, to the extent permitted
by law, will be the CEO and an additional senior executive (the "Management
Public Directors" and with the Outside Public Directors, the "Public
Directors"), (ii) four independent directors (the "Independent Directors")
elected by the holders of Class I Junior Preferred Stock, and intended to be a
quasi-self-perpetuating body, (iii) three directors representing various
employee groups elected as follows: (a) the ALPA Director elected by the Class
Pilot MEC Junior Preferred Stock, which will be held by the ALPA-MEC, (b) the
IAM Director elected by the Class IAM Junior Preferred Stock, which will be
held by the IAM or its designee, and (c) the Salaried and Management Director
elected by the Class SAM Preferred Stock, which will be held by the Salaried
and Management Director and an additional designated stockholder. See "THE PLAN
OF RECAPITALIZATION--Revised Governance Structure--Composition of the Board--
Public Directors," "--Independent Directors," "--Employee Directors" and
"ELECTION OF DIRECTORS."     
   
  Generally, Board actions will require a majority vote of the votes present at
a meeting at which a quorum is present. Special quorum requirements apply to
meetings of the Board. However, approval of certain extraordinary matters
generally will require, subject to certain exceptions, approval of either
three-quarters of the Board (including the concurrence of one Union Director)
or three-quarters of the shares present and voting at a stockholder meeting at
which a quorum is present. Certain extraordinary matters will require     
 
                                      xix
<PAGE>
 
   
approval of the Public Directors, the Independent Directors or a majority of
New Shares not held by the ESOPs. See "THE PLAN OF RECAPITALIZATION--Revised
Governance Structure--Quorum," "--Required Board Action" and "--Extraordinary
Matters."     
   
  The Restated Certificate provides that until the Sunset the following
committees will be constituted: the Audit Committee, the Competitive Action
Plan ("CAP") Committee, the Compensation Committee, the Compensation
Administration Committee, the Executive Committee, the Independent Director
Nomination Committee, the Labor Committee, the Outside Public Director
Nomination Committee and the Transaction Committee (collectively, the
"Committees"). In addition, the Board may, by resolution passed by the
affirmative vote of 80% of the votes of the entire Board, including the
affirmative vote of at least one Union Director, designate one or more other
committees of the Board. Subject to certain exceptions, any act of a Committee
will require the affirmative vote of a majority of the votes entitled to be
cast by the Directors present at a meeting of such Committee and entitled to
vote on the matter in question. The Restated Certificate contains certain
provisions relating to the required quorum for committee action. See "THE PLAN
OF RECAPITALIZATION--Revised Governance Structure--Committees."     
   
  The CAP Committee will consist of eight Directors, including four Public
Directors, two Independent Directors and the two Union Directors. Of the four
Public Directors, three will be Outside Public Directors and one will be the
CEO (if the CEO is a Public Director). The function of the CAP Committee will
be, subject to certain exceptions, to oversee implementation of the Company's
Competitive Action Plan which will involve implementation of U2. The CAP
Committee will have the exclusive authority to approve on behalf of the Company
any and all modifications of or amendments to the Competitive Action Plan and
to approve on behalf of the Company any and all modifications of or amendments
to the salaried and management employee investment described in "THE PLAN OF
RECAPITALIZATION--Investment for Salaried and Management Employees."     
   
  The Executive Committee will be comprised of two Independent Directors, two
Public Directors (the CEO, if the CEO is a Public Director, and one Outside
Public Director) and two Union Directors. Subject to the DGCL, the Executive
Committee will have all the powers of the Board to manage the affairs of the
Company, except that it would not have the authority (i) to act with respect to
"Extraordinary Matters," discussed under "THE PLAN OF RECAPITALIZATION--Revised
Governance Structure--Extraordinary Matters," (ii) to take any action as to
matters specifically vested in other Committees or (iii) to take any action
that may be taken by the Board only with a vote greater than or additional to a
majority of the Board.     
   
  The Labor Committee will consist of three or more Directors, including one
Outside Public Director, at least one Independent Director and at least one
other Director, as designated by the Board, but will not include any Employee
Directors. The Labor Committee will have the exclusive authority on behalf of
the Board to approve on behalf of the Company the entering into, or any
modification of or amendment to, a collective bargaining agreement to which the
Company or any of its Subsidiaries is a party.     
   
  The Compensation Administration Committee will be comprised of two
Independent Directors and one Outside Public Director and its members will be
responsible for administering certain stock option plans and executive
compensation programs of the Company.     
   
  Fraudulent Conveyance. If a court in a lawsuit by an unpaid creditor or
representative of creditors, such as a trustee in bankruptcy, were to find
that, at the time the Company distributed to holders of Old Shares the cash and
Debentures that such holders are to receive in the Recapitalization, the
Company (i) was insolvent, (ii) was rendered insolvent by reason of such
distributions, (iii) was engaged in a business or transaction for which the
assets remaining with the Company constituted unreasonably small capital to
carry on its business or (iv) intended to incur, or believed that it would
incur, debts beyond its ability to pay as such debts matured, such court may
void the distributions to stockholders and require that such holders return the
same (or equivalent amounts) to the Company or to a fund for the benefit of its
creditors. If a     
 
                                       xx
<PAGE>
 
   
court were to make similar findings about United's issuance of the Debentures,
such court could avoid United's obligations under the Debentures or order the
Debentures to be subordinated to all existing and future indebtedness of
United. The measure of insolvency for purposes of the foregoing would vary
depending upon the law of the jurisdiction that was being applied. Generally,
the Company would be considered insolvent if at the time of the
Recapitalization the fair value of the Company's assets is less than the amount
of the Company's total debts and liabilities or if the Company has incurred
debt beyond its ability to repay as such debt matures. In order to assist the
Board to determine the solvency of the Company, the Company retained American
Appraisal.     
   
  As stated in "SPECIAL FACTORS--Opinion of Valuation Firm," the American
Appraisal Opinion stated that, based upon and subject to the conditions and
assumptions contained therein, (a) the fair value of the aggregate assets of
each of the Company (on a consolidated basis) and United (on a consolidated
basis) will exceed their total respective liabilities (including, without
limitation, subordinated, unmatured, unliquidated and contingent liabilities),
(b) the present fair salable value of the aggregate assets of each of the
Company (on a consolidated basis) and United (on a consolidated basis) will be
greater than their respective probable liabilities on their debts as such debts
become absolute and matured, (c) each of the Company (on a consolidated basis)
and United (on a consolidated basis) will be able to pay their respective debts
and other liabilities, including contingent liabilities and other commitments,
as they mature, (d) the capital remaining in each of the Company (on a
consolidated basis) and in United (on a consolidated basis) after consummation
of the Recapitalization will not be unreasonably small for the businesses in
which the Company and United are engaged, as management of the Company and
United has indicated such businesses are conducted and as management has
indicated the businesses are proposed to be conducted following the
consummation of the Recapitalization, and after giving due consideration to the
prevailing practices in the industry in which the Company and United will be
engaged, (e) the excess of the fair value of the total assets of the Company
over the total liabilities, including contingent liabilities, of the Company,
is equal to or exceeds the value of the Recapitalization Consideration to
stockholders plus the stated capital of the Company and (f) the excess of the
fair value of the total assets of United over the total liabilities, including
contingent liabilities, of United, is equal to or exceeds the value of the
stated capital of United.     
   
  American Appraisal also indicated that it believed the excess of total assets
over pro forma liabilities was approximately $2.5 billion at December 31, 1993,
compared to approximately $1.203 billion in stockholders' equity as of such
date, determined according to generally accepted accounting principles, so
that, giving effect to the Recapitalization, the indicated excess assets of the
Company for purposes of Delaware law exceeded $1 billion. See "SPECIAL
FACTORS--Certain Risk Factors--Fraudulent Conveyance," "--Certain Revenue and
Earnings Scenarios" and "UNAUDITED PRO FORMA FINANCIAL INFORMATION."     
   
  Certain Antitakeover Effects. Certain provisions of the governance structure
will make it extremely difficult to acquire the Company in a transaction that
was not approved by at least one of the Union Directors or a 75% vote of the
New Shares and the Voting Preferred Stock, even if such transaction might be
beneficial to the Company's stockholders. See "THE PLAN OF RECAPITALIZATION--
Revised Governance Structure."     
   
  Pricing of Public Preferred and Debentures. As described in "THE PLAN OF
RECAPITALIZATION--Terms and Conditions--Pricing of the Securities," the final
interest rates on the Debentures and the final dividend rate on the Public
Preferred Stock will be established shortly prior to the Meeting. Although the
procedure for establishing such final rates is designed to determine the rates
that such securities should bear for the Debentures and the Depositary
Preferred Shares representing interests in the Public Preferred Stock to trade
at par assuming such securities were fully distributed, the Plan of
Recapitalization provides that such rates may not exceed certain caps. The
underwriting agreements relating to the Offerings will provide that if the
Offerings are consummated, the interest rates on the Debentures and the
dividend rate on the Public     
 
                                      xxi
<PAGE>
 
   
Preferred Stock may be adjusted to permit the Debentures and the Depositary
Preferred Shares to be sold at or closer to par, but if that is done, the
principal amount of the series of Debentures affected or the number of
Depositary Preferred Shares representing interests in the Public Preferred
Stock, as the case may be, will be reduced so that the aggregate amount of
interest payable annually by United on the Debentures or the aggregate amount
of dividends payable annually by the Company on the Public Preferred Stock will
not exceed certain maximum amounts calculated with reference to such caps. If
the Offerings are not consummated, the interest rates borne by the Debentures
and the dividend rate borne by the Public Preferred Stock will be subject to
the caps. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--Pricing the
Securities." If the prevailing market interest and dividend rates for
securities comparable to the Debentures and the Depositary Preferred Shares are
higher than the rate caps applicable to the Debentures or the Public Preferred
Stock, as the case may be, the Debentures or the Depositary Preferred Shares
representing interests in the Public Preferred Stock, as the case may be, may
trade at a discount to par. Accordingly, if the rate caps are imposed for some
or all of the Debentures or the Depositary Preferred Shares, (a) the proceeds
from the Offerings, if the Offerings are consummated, could be less than the
face amount thereof or (b) if the Offerings are not consummated, the securities
constituting a part of the Mixed Recapitalization Consideration would have a
trading value of less than the face amount thereof. Based on the current
general market conditions, the Company believes that the rates for some or all
of the Debentures or the Depositary Preferred Shares may approach or exceed the
maximum rates.     
   
  Investment Values; Future Investment. Cost savings envisioned by the
agreements with ALPA and the IAM and the anticipated productivity increases
could be difficult to achieve, and even if all proposed plans for employee
investment are implemented, the value of the reductions in wages and benefits
and work-rule changes and anticipated productivity increases may not be as
significant as currently calculated. Mandated job guarantees may make it
difficult to achieve significant additional productivity improvements, and, if
additional reductions in wages and benefits and work-rule changes become
desirable in management's view, such reductions in wages and benefits and work-
rule changes may be more difficult to achieve in light of the long-term nature
of the revised collective bargaining agreements that constitute elements of the
Recapitalization.     
   
  Lack of Employee Consensus. Certain employee groups may not be in favor of
the changes arising from the Recapitalization and may react in a manner that
does not facilitate achievement of the desired result. For example, the AFA has
declined to date to participate in the transaction, certain other employees who
will be participating in the wage and benefit reductions and work-rules changes
were not in favor of the transaction, and certain union organizing activity,
based on opposition to certain aspects of the transaction, has occurred. This
lack of consensus may reduce the value of the increased employee commitments
that the Company expects to achieve by virtue of the Recapitalization.     
 
  Management Change. The new CEO, Mr. Gerald M. Greenwald, will be required to
implement reductions in wages and benefits and work-rule changes that were
negotiated by the current management, certain members of which will retire at
the Effective Time, in an industry in which he has not previously been engaged.
In addition, it is possible that the Company may face attrition by officers and
other members of management and that the Company's new senior management may
face difficulties in implementing the new strategies or attracting additional
management employees.
   
  Reduced Flexibility. The corporate governance structure and collective
bargaining agreements with ALPA and the IAM may inhibit management's ability to
alter strategy in a volatile, competitive industry. Among the more significant
constraints are (i) a prohibition on domestic code sharing in excess of 1% of
domestic block hours, excluding several small existing agreements, without
ALPA's consent, (ii) a no layoff guarantee for all currently employed
participating union employees during the five- to six-year investment period
and for pilots while U2 remains in operation, (iii) restrictions on
international code sharing, unless the Company can demonstrate that
international code sharing arrangements do not cause a reduction in     
 
                                      xxii
<PAGE>
 
   
international flying and as long as the Company does not expand code sharing
unless the Company reduces international flying below a certain level and (iv)
an agreement not to sell the Company's Denver pilot training facility and
certain maintenance facilities. In addition, the Restated Certificate contains
significant limitations on the ability of the Company and United to sell assets
and issue equity securities absent certain specified Board or stockholder
approvals. In most circumstances, the issuance of additional equity securities
would not be counted in determining whether the Sunset has occurred.     
   
  Limitations on asset sales and equity issuances included in the Company's
Restated Certificate might make it more difficult to raise cash, even if
management desired to do so to take advantage of a perceived opportunity.     
   
  Implementation of U2. Although the Company expects to develop "an airline
within-an-airline" for short-haul markets at reduced operational costs ("U2")
as an important component of its competitive posture and has ascribed a
significant portion of the value of the transaction to the ability to implement
U2, no assurance can be given that the Company will be able to do so
effectively or to realize the financial benefits expected to be received by the
Company from implementation of U2. See "SPECIAL FACTORS--Implementation of the
"Airline Within-an-Airline' (U2)" and "--Certain Risk Factors--Implementation
of U2."     
   
  Competitive Response. Even if the Company is able to achieve cost reductions
and productivity enhancements, the Company's higher cost competitors may be
able to achieve comparable agreements with their labor groups or otherwise
reduce their operating costs and the Company's low-cost competitors may modify
their operations in response to the competitive threat posed by U2 and thus, in
such cases, may eliminate or reduce the competitive gain sought by the Company
and lead to reductions in fares and earnings. In this regard, for example,
Continental Airlines (which already has a low cost structure) has implemented a
short haul service with lower costs which would be competitive with U2, and
Delta Airlines has announced its intent to lower its overall costs
substantially. If the Company's higher cost competitors, such as Delta, were to
achieve more significant reductions in wages and benefits and work-rule changes
than those achieved by the Company, the Company's ability to respond to
competition would be hampered by the fixed long-term nature of the agreements
that constitute elements of the Recapitalization.     
 
  Labor Protective Provisions. The Company will continue in effect, or amend to
include, certain provisions of agreements with ALPA and the IAM that (i)
provide certain rights in the event of a change in control of the Company and
(ii) prohibit furloughs, within certain conditions, if the Company disposes of
25 percent or more of its assets or assets which produce 25 percent or more of
its block hours. The revised collective bargaining agreements obligate the
Company to require any carrier purchasing route authority or aircraft that
produce 25 percent or more of the Company's operating revenues or block hours
to hire and integrate an appropriate number of United employees with seniority
credit.
 
  Tax Deductibility of Employee Stock Ownership Plan Contributions and
Dividends. Although the Company has attempted to structure the ESOPs so that
all amounts contributed thereto and dividends paid with respect to the stock
held thereunder will be deductible to the Company for Federal income tax
purposes, there are no regulations governing the deductibility of dividends
paid on the ESOP Preferred Stock and there can be no assurance that one or more
limitations under the Internal Revenue Code of 1986, as amended, will not
adversely impact the deductibility of such amounts and dividends.
       
   
  Amendments to Collective Bargaining Agreements; Future Labor
Agreements. There can be no assurance that the new management of the Company in
the future will not agree to amend the collective bargaining agreements with
ALPA and the IAM in a manner that reduces or eliminates the cost savings that
are the basis for the Recapitalization. However, any such amendment must be
approved by the Labor Committee of the Board (which will not include any Union
Directors). See "THE PLAN OF RECAPITALIZATION--Revised Governance Structure--
Committees." In addition, at the end of the     
 
                                     xxiii
<PAGE>
 
current employee investment period, there can be no assurance that the
Company's labor agreements will be renegotiated in a manner that continues in
subsequent periods the cost savings that are being sought through the
Recapitalization or that does not reverse the effect of any cost savings that
will have been obtained thereby.
 
  Possible Effect of Organization of Additional Employees. In the event that
any portion of the salaried and management employees who are not currently
represented by a union elects union representation pursuant to the Railway
Labor Act, the Company would be obligated to bargain with such union over the
terms and conditions of employment applicable to such employees, including the
terms, if any, of such employees' continuing participation in the ESOPs. This
obligation to bargain requires the Company to "exert every reasonable effort"
to reach an agreement but does not require it to agree to any change or
particular term or condition sought by the union. During the period of
negotiation, the Company would be entitled to maintain the then-existing terms
of such employees' participation in the ESOPs.
 
  The ESOPs provide that if any group of employees who are not currently
represented by a union becomes covered by a new collective bargaining
agreement, such group of employees will not be covered under the ESOPs unless
the collective bargaining agreement so provides. Whether any new collective
bargaining agreement would provide for continuing participation in the ESOPs by
such group of employees is a matter that would be subject to mutual agreement
between the Company and the applicable union. The ESOPs provide, however, that
if the terms of any employee's employment no longer reflect all of the
reductions in wage and benefits and work-rule changes set forth in the Plan of
Recapitalization, then such employee shall cease to be covered by the ESOPs.
   
  As a result, if any new collective bargaining agreement did not reflect the
reductions in wage and benefits and work-rule changes required by the Plan of
Recapitalization for particular employees, the Company could not agree, without
amending the ESOPs, to allow such employees to participate in the ESOPs. If any
currently unrepresented employees ceased to participate in the ESOPs under such
circumstances, the ESOPs provide that the unrepresented employees remaining in
the ESOPs would receive the shares previously intended for that newly-
represented group. The employment terms, except base pay, for the unrepresented
employees remaining in the ESOPs will be subject to change, at the Company's
discretion, so long as the net economic value of the unrepresented employees'
employment terms is not altered.     
   
  Employee Ownership and Influence. No assurance can be given that the Company,
which will be subject to significant influence by employee groups (including
through the right to voting representation in excess of economic equity
ownership, Board and Board committee representation, the requirement of
approval of certain matters by a Union Director or a 75% vote of the holders of
New Shares and Voting Preferred Stock, and participation by Union Directors in
the nomination of the Independent Directors), might not take actions that are
more favorable to such employee groups than might be taken by a company that
was not subject to such influence. The corporate governance structure after the
Recapitalization will not, however, relieve the members of the Board of their
fiduciary obligations under the DGCL.     
   
  Effect of Adjustment on Trading. As described under "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Additional Shares," the ESOP
Preferred Stock which the Company is initially obligated to issue or credit to
the ESOPs is convertible into approximately 55% of the New Shares but, based on
the trading prices of the New Shares in the twelve months after the Effective
Time (the "Measuring Period"), may be increased to up to a maximum of
approximately 63% of the New Shares. Such potential additional issuance may
adversely limit the trading prices of the New Shares during the Measuring
Period.     
   
  Additional Issuances of Recapitalization Consideration. United has registered
under the Securities Act $449,802,200 aggregate principal amount of each series
of Debentures and the Company has registered 35,984,175 Depositary Preferred
Shares representing interests in $899,604,375 aggregate liquidation value of
the Public Preferred Stock. If the Offerings are not consummated, United and
the Company may be required     
 
                                      xxiv
<PAGE>
 
   
to issue a larger number of Debentures and Depositary Preferred Shares in
connection with the exercise of Options (as defined below) in the event holders
thereof fail to use a cashless exercise feature or in connection with the
conversion of certain Convertible Company Securities (as defined below).
However, the failure of Option holders to utilize a cashless exercise feature
would have the effect of increasing the Company's available cash by an amount
equal to the aggregate exercise price. See "DESCRIPTION OF SECURITIES--The
Debentures--General" and "--The Public Preferred Stock--General." If the
Offerings are not consummated, the Company currently intends to register in the
future additional securities originally issued (or distributed following
repurchase in the market), to satisfy the exercise or conversion of Options or
Convertible Company Securities.     
   
  Financial Reporting; Market Assessment. The accounting rules governing
employers accounting for employee stock ownership plans require that
compensation expense be recorded for the ESOP Preferred Stock that is
"committed to be released" during an accounting period based on the fair value
of the ESOP Preferred Stock during such period. The difference between the fair
value and the initial recorded cost of the ESOP Preferred Stock "committed to
be released" is recorded as an adjustment to stockholders' equity. The ESOP
Preferred Stock that has been "committed to be released" is considered to be
outstanding in the if-converted earnings per share calculation for primary and
fully diluted earnings per share if the effect is dilutive. The circular
relationship between the employee stock ownership plan accounting charge and
the Company's stock price, coupled with the size of the contemplated ESOPs,
make future earnings difficult to forecast. In addition, reported book earnings
will be depressed in early years due to a mismatch between the term of employee
investments (which increase earnings) of from five years, nine months to twelve
years and the shorter period of only six years over which employee stock
ownership plan accounting charges will occur. While it is possible that the
equity research community and investors may look through employee stock
ownership plan accounting charges, it is also possible that the trading price
of the New Shares may be negatively impacted by such accounting treatment.     
   
  Possible Cancellation of Facility. United is a party to a $500 million
commercial paper facility through agreements with United Airlines First Funding
Corporation ("First Funding") and certain banks. As of the date of this Proxy
Statement/Prospectus, approximately $270 million of commercial paper is
outstanding under such facility. As a result of provisions in the Second
Amended and Restated Credit Agreement, dated as of September 20, 1993 (the
"Credit Agreement"), among First Funding, Union Bank as agent and certain other
banks, a "change in control" may be deemed to occur as a result of the
Recapitalization, and First Funding may be restricted from issuing new
commercial paper under the Credit Agreement. Although this will not have an
effect on outstanding commercial paper under the Credit Agreement, the Company
will need either to renegotiate the Credit Agreement or to obtain an alternate
funding source to replace such facility with respect to future fundings.
Although the Company does not expect it to be the case, the Company may not be
able to renegotiate or to obtain such alternate facility, in which case the
Company's liquidity may be impaired.     
       
  Complexity. Given the complex nature of the various provisions affecting the
operation of the Company after the Effective Time, it is possible that the
equity research community and investors may find the Company difficult to
evaluate, which may have the effect of reducing the trading price of the New
Shares from levels that might otherwise prevail.
   
  Redistribution. If the Offerings are not consummated, in the
Recapitalization, holders of Old Shares (an equity security) will receive
Debentures and Depositary Preferred Shares representing interests in Public
Preferred Stock in addition to New Shares and cash. It is expected that there
will exist a period, perhaps of a lengthy duration, during which certain
recipients of such securities, concluding that the characteristics thereof are
not consistent with their investment criteria, distribute such securities into
the marketplace. During such distribution period, the supply of such securities
in the market may exceed levels that might     
 
                                      xxv
<PAGE>
 
   
otherwise prevail, which would likely have the effect of depressing the price
of such securities from levels that might otherwise prevail if such securities
were held solely by persons or institutions for whom such securities satisfied
their investment criteria. In addition, although the Company expects that it
will apply for listing of the Debentures and the Depositary Preferred Shares on
the NYSE, there can be no assurance that at or following the Effective Time
such securities will be listed on the NYSE or any other securities exchange or
that any trading market for the securities will develop.     
 
  Industry Conditions and Competition. The airline industry is highly
competitive and susceptible to price discounting. United's competitors include
both domestic and international carriers some of which have low cost
structures. In addition, airline profit levels are highly sensitive to elements
outside the control of the airline industry such as fuel costs, passenger
demand, taxes and terrorist activities.
 
  Regulatory Matters. In the last several years, the Federal Aviation
Administration (the "FAA") has issued a number of maintenance directives and
other regulations relating to, among other things, collision avoidance systems,
airborne windshear avoidance systems, noise abatement and increased inspection
requirements. The Company expects to continue incurring costs to comply with
the FAA's regulations. Additional laws and regulations have been proposed from
time to time that could significantly increase the cost of airline operations
by, for instance, imposing additional requirements or restrictions on
operations. Laws and regulations have also been considered from time to time
that would prohibit or restrict the ownership and/or transfer of international
airline routes or takeoff and landing slots. Also, the award of international
routes to U.S. carriers (and their retention) is regulated by treaties and
related agreements between the United States and foreign governments, which are
amended from time to time. For example, there are significant aviation issues
between the United States and such foreign governments as Germany, Japan and
the United Kingdom that, depending on their resolution, may significantly
impact the Company's existing operations or curtail potential expansion
opportunities in important regions of the world. The Company cannot predict
what laws and regulations will be adopted or what changes to international air
transportation treaties will be effected, if any, or how they will affect
United.
   
  Holding Company Structure The Company is a holding company that conducts
operations solely through its subsidiaries, principally United. The Company
will rely on dividends from its subsidiaries to meet its cash requirements,
including cash requirements in connection with dividends on or redemptions of
Depositary Preferred Shares (and the Public Preferred Stock interest). As a
result of the recapitalization, United will have substantial debt in relation
to its stockholder's equity, as determined on a pro forma basis pursuant to the
application of generally accepted accounting principles.     
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
   
  The Recapitalization is expected not to be a taxable transaction to the
Company but will be a taxable transaction to the Company's stockholders. A
summary of certain Federal income tax consequences of the Recapitalization for
stockholders is set forth under "CERTAIN FEDERAL INCOME TAX CONSEQUENCES." See
also "SPECIAL FACTORS--Certain Risk Factors--Taxation of Recapitalization to
Stockholders."     
 
NO APPRAISAL RIGHTS
   
  Stockholders of the Company will not be entitled to appraisal rights in
connection with any of the matters to be voted upon at the Meeting. For a
description of pending litigation related to the Recapitalization, see
"LITIGATION."     
 
MARKET PRICES OF THE OLD SHARES; DIVIDENDS

  No dividends have been declared on the Old Shares since 1987.
   
  On December 22, 1993, the last trading day prior to the public announcement
of the Agreement in Principle, the closing sales price for the Old Shares as
reported on the NYSE Composite Tape was $148 1/2 per share. On March 24, 1994,
the last trading day prior to the public announcement of the execution of the
Plan of Recapitalization, the closing sales price for the Old Shares as
reported on the NYSE Composite Tape was $123 3/4 per share. On June  , 1994,
the last trading day prior to the date of this Proxy Statement/Prospectus, the
closing sales price for the Old Shares as reported on the NYSE Composite Tape
was $  . STOCKHOLDERS SHOULD OBTAIN CURRENT MARKET QUOTATIONS FOR THE OLD
SHARES AS ONE OF THE FACTORS RELEVANT TO ASSESSING THE VALUE OF THE NEW SHARES
BEFORE VOTING ON THE PLAN OF RECAPITALIZATION. The New Shares are expected to
be listed on the NYSE.     
   
  The Board does not expect to declare the regular dividend for the second
quarter of 1994, and if the Recapitalization is consummated, the Company does
not expect to pay dividends in the foreseeable future on the New Shares. See
"SPECIAL FACTORS--Certain Risk Factors."     
 
UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL POSITION
   
  The following are the unaudited Statements of Pro Forma Consolidated
Financial Position for each of the Company and United. These statements are
based on an assumed purchase price for the Class 1 ESOP Preferred Stock at the
Effective Time of $120 per share. The $120 per share assumed purchase price of
Class 1 ESOP Preferred Stock is based on [(i) an assumed market price of an Old
Share at the Effective Time of $131 per share, (ii) an assumed value of the
non-New Share portion of the Recapitalization Consideration of $88 per Old
Share, and (iii) a purchase price premium for the Class 1 ESOP Preferred Stock
over the assumed value of a New Share of 38%.] The actual purchase price for
the Class 1 ESOP Preferred Stock at the Effective Time will be determined using
a formula based on (i) the greater of the pre-Effective Time when issued market
price of the New Shares and the pre-Effective Time market price of the Old
Shares, (ii) [an expected value] for the non-New Share portion of the
Recapitalization Consideration and (iii) a 38% purchase price premium. See "THE
PLAN OF RECAPITALIZATION--Establishment of ESOPs--Sale of ESOP Preferred
Stock--Leveraged ESOP." There can be no assurance as to the actual purchase
price of the Class 1 ESOP Preferred Stock, the pre-Effective Time when issued
market price of the New Shares, the pre-Effective Time market price of the Old
Shares, or the value of the non-New Share portion of the Recapitalization
Consideration.

These statements do not purport to be indicative of the financial position that
may be obtained in the future or that would actually have been obtained had the
Recapitalization occurred on the dates indicated.     
       
                    UAL CORPORATION AND SUBSIDIARY COMPANIES
   
  The following statement sets forth the unaudited consolidated financial
position of the Company and its subsidiaries at March 31, 1994, and the
unaudited pro forma consolidated financial position of the Company and its
subsidiaries after giving effect to the Recapitalization and the Offerings, and
the payment of fees and expenses incurred in connection with the
Recapitalization. The statement should be read in conjunction with the selected
consolidated financial and operating information, the unaudited pro forma
financial information and the respective related notes thereto appearing
elsewhere herein. See "SELECTED CONSOLIDATED FINANCIAL AND OPERATING
INFORMATION--UAL Corporation and Subsidiary Companies" and "UNAUDITED PRO FORMA
FINANCIAL INFORMATION--UAL Corporation and Subsidiary Companies." In addition,
the statement should be read in conjunction with the Company's Annual Report on
Form 10-K for the year ended December 31, 1993 and Quarterly Report on Form 10-
Q for the quarter ended March 31, 1994, as amended, which are included
elsewhere in this Proxy Statement/Prospectus and which include the Company's
Consolidated Financial Statements, the related notes thereto and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."     
   
  The pro forma statement assumes the Recapitalization is not accounted for as
an acquisition or merger and, accordingly, UAL's assets and liabilities have
not been revalued. The reclassification of Old Shares into New Shares results
in the elimination of the par value of the Old Shares and recognition of the
par value of the New Shares. The distribution of cash to holders of Old Shares
is charged to additional capital invested and retained earnings.     
   
  The ESOPs are being accounted for in accordance with the American Institute
of Certified Public Accountants Statement of Position 93-6, "Employers'
Accounting for Employee Stock Ownership Plans" ("SOP"). For the Leveraged ESOP,
the Company will issue Class 1 ESOP Preferred Stock through seven ESOP Tranches
beginning at the Effective Time, thirteen months following the Effective Time,
annually thereafter for four years with a final ESOP Tranche on January 1,
2000. As the shares are issued to the Leveraged ESOP, the Company will report
the issuance of shares as a credit to additional capital invested based on the
fair value of the stock when it occurs and report a corresponding charge to
unearned ESOP Preferred Stock. As consideration for the shares, the Company
will receive from the ESOP Trustee a series of promissory notes and cash. The
notes will not be recorded in the Company's Statement of Consolidated Financial
Position and the related interest income will also not be recorded in the
Company's Statement of Consolidated Operations. As shares of Class 1 ESOP
Preferred Stock are earned or "committed to be released," an employee stock
ownership plan accounting charge will be recognized equal to the average fair
value of the shares committed to be released with a corresponding credit to
unearned ESOP Preferred Stock. Any differences between the fair value of the
shares committed to be released and the cost of the shares to the ESOP will be
charged or credited to additional capital invested. For the Non-Leveraged
Qualified ESOP and the Supplemental ESOP, a credit for the shares of Class 2
ESOP Preferred Stock will be recorded as the shares are committed to be
contributed to the ESOP, with the offsetting entry to compensation expense.
Compensation expense will be recorded based on the fair value of the shares
committed to be contributed to the ESOP, in accordance with the SOP.     
       
   
  The ESOP Preferred Stock is considered to be a common stock equivalent since
the shares cannot remain outstanding indefinitely and participants cannot
withdraw their shares from the plan. Under the SOP, when computing primary and
fully diluted earnings per share, only those shares committed to be released
are considered outstanding as common stock equivalents. Prospectively, as
dividends are paid by UAL to the ESOP, only dividends on allocated shares will
be recorded as a charge to equity. Since UAL controls the use of the dividends
on unallocated ESOP Preferred Stock, such dividends will be recorded as
compensation expense.

                 UAL CORPORATION AND SUBSIDIARY COMPANIES     
   
      NOTES TO PRO FORMA STATEMENT OF CONSOLIDATED FINANCIAL POSITION     
       
   
(1) To record the Recapitalization (as described in "THE PLAN OF
    RECAPITALIZATION--Terms and Conditions"). The entries assume that (i) the
    Offerings of Debentures and Depositary Preferred Shares representing
    interests in Public Preferred Stock are consummated, (ii) all in-the-money
    options are vested and exercised at the Effective Time using a cashless
    exercise mechanism, (iii) treasury stock held by the Company immediately
    prior to the Effective Time will convert into New Shares that remain
    outstanding after the Recapitalization and (iv) Convertible Company
    Securities that are outstanding immediately prior to the Effective Time
    will not convert into the Recapitalization Consideration at the Effective
    Time. The cashless exercise feature permits holders of Options to exercise
    them by surrendering to the Company a portion of the proceeds of the Option
    in lieu of paying the exercise price in cash. When the cashless exercise
    feature is used, each element of the Recapitalization Consideration that is
    issuable upon the exercise of such Options is reduced proportionately, and
    the net Recapitalization Consideration (including the New Shares) that is
    issued is equal in value to the spread value of the Options exercised. See
    footnote number 8 to the Pro Forma Condensed Statement of Consolidated
    Operations for the year ended December 31, 1993.     
     
  (a) To record the proceeds from the Offerings of approximately $765 million
      of Debentures and approximately $765 million of Depositary Preferred
      Shares representing interests in Public Preferred Stock, net of
      underwriting discount of $7 million for the Debentures and $25 million
      for the Public Preferred Stock. (If the Offerings are not consummated,
      the Debentures and the Depositary Preferred Shares included in entry
      1(c) and 1(d) will be issued to the holders of Old Shares upon
      redemption of the Redeemable Preferred Stock.)     
     
  (b) To record the cash payment to holders of Old Shares upon the redemption
      of the Redeemable Preferred Stock. The cash payment includes $25.80 per
      share plus proceeds from the sales of $31.10 of face amount Debentures
      and Depositary Preferred Shares representing interests in $31.10
      liquidation preference of Public Preferred Stock (before deducting
      underwriting discount), and assumes that the proceeds of the sales
      equals the face amount of the securities. The pro forma adjustment also
      includes the cash payment of $88 per share upon exercise of Options.
      (If the amount to be sold in the Offerings is reduced as discussed in
      entry 1(c) and 1(d), the amount paid to holders of Old Shares will be
      reduced.)     
     
  (c) To record the issuance of $382.5 million of principal amount of Series
      A Debentures and $382.5 million of principal amount of Series B
      Debentures. The Debentures are being recorded at their face amount on
      the assumption that they will be priced to trade at par, less the
      underwriting discount of $7 million. The actual rate on the Debentures
      will be reset prior to the Effective Time and the Debentures are
      subject to a maximum interest rate of 112.5 basis points above the
      Initial Pricing. The underwriting agreement for the Offerings are
      expected to provide that if the Offerings are consummated, the interest
      rate may be adjusted in order for the Debentures to be sold at or close
      to par, in which case the principal amount of the Debentures will be
      reduced so that the annual interest expense will not exceed the stated
      maximum which was calculated based upon the rate cap. If the Offerings
      are not consummated and the interest rate exceeds the cap, the
      Debentures will be recorded at a discount.     
     
  (d) To record the issuance of Depositary Preferred Shares representing
      interests in $765 million liquidation preference of Public Preferred
      Stock, net of underwriting discount of $25 million. The Public
      Preferred Stock is recorded at its stated value of $.01 per share, with
      the excess of liquidation value over stated value and net of
      underwriting discount recorded as additional capital invested. The
      dividend rate on the Public Preferred Stock will be reset prior to
      Closing and is subject to a     
 
                                      xxx
<PAGE>
 
        
     maximum of 11.375%. If the Offering is consummated, the dividend rate
     may be adjusted in which case the number of Depositary Preferred Shares
     will be reduced.     
     
  (e) To record the reclassification of Old Shares into New Shares and
      Redeemable Preferred Stock. The Redeemable Preferred Stock is assumed
      to immediately convert to cash, including proceeds from the sale of
      Debentures and Depositary Preferred Shares representing interests in
      Public Preferred Stock. (The pro forma adjustments do not reflect the
      Redeemable Preferred Stock issued to the Company upon reclassification
      of the treasury stock because such shares are surrendered for
      cancellation immediately after issuance.)     
       
    The New Shares are recorded at their par value of $.01 per share.
    Following is a summary of the entries to additional capital invested and
    retained earnings (in millions):

(2) To record the cash impact of the estimated fees and transaction expenses,
    including expenses for the Company, ALPA and the IAM, severance payments to
    terminated officers and flight kitchen employees and payments relating to
    the employment agreement with Mr. Greenwald.     
   
(3) To record the tax effects relating to nonrecurring charges recognized as a
    result of the Recapitalization.     
   
(4) To record the initial issuance of Class 1 ESOP Preferred Stock to the
    Leveraged ESOP for an aggregate purchase price of $228 million. The $228
    million was determined based on (i) 1,899,059 shares of Class 1 ESOP
    Preferred Stock expected to be issued in the first ESOP Tranche as of the
    Effective Time and (ii) an assumed purchase price of $120 per share. UAL
    and the Unions may, prior to the Effective Time, agree to increase or
    decrease the number of shares of Class 1 ESOP Preferred Stock sold at the
    Effective Time. The agreement with the ESOP Trustee provides that the
    number of shares of Class 1 ESOP Preferred Stock sold at the Effective Time
    shall be no more than 2,088,965 and no fewer than 1,709,153. The actual
    price per share for the first ESOP Tranche will be 1.38 times the average
    price of a New Share at the Effective Time. Thus, the ultimate amount
    recorded at the Effective Time will differ from the pro forma adjustment in
    order to reflect the actual number of shares issued and the average closing
    price of the New Shares.     
     
  Six additional ESOP Tranches will be issued to the Leveraged ESOP during
  the 69 months subsequent to the Effective Time, with the total shares of
  Class 1 ESOP Preferred Stock issued in the seven ESOP Tranches aggregating
  approximately 14,000,000 shares (subject to increase, see "THE PLAN OF
  RECAPITALIZATION--Establishment of ESOPs--Additional Shares). The price for
  the subsequent ESOP Tranches will be as agreed between the Company and the
  ESOP Trustee at the time of each sale. As the subsequent ESOP Tranches are
  issued, the shares will be reported as a credit to additional capital
  invested based on the fair value of the stock when such issuances occur
  with a corresponding charge to "Unearned ESOP Preferred Stock."     
     
  The Unearned ESOP Preferred Stock recorded in the pro forma adjustment
  together with the Unearned ESOP Preferred Stock recorded from subsequent
  ESOP Tranches will be recognized as compensation expense over the
  approximately six year investment period as the shares are committed to be
  released. The difference between the compensation expense recorded, which
  is based on the fair value of the stock     
 
                                      xxxi
<PAGE>
 
   
  during an accounting period, and the recorded cost of the unearned ESOP
  Preferred Stock will be recorded to additional capital invested.     
   
  The shares of Class 2 ESOP Preferred Stock will be recorded over the
  approximately six year investment period as the shares are committed to be
  contributed to the Non-Leveraged Qualified ESOP and credited to employees
  pursuant to the Supplemental ESOP with the offsetting entry being to
  compensation expense. The number of shares of Class 2 ESOP Preferred Stock
  that will be issued will be equal to 17,675,345 less the number of shares
  of Class 1 ESOP Preferred Stock that will be sold to the Qualified ESOP.
      
   
  The ESOP Preferred Stock is convertible into New Shares at any time at the
  election of the ESOP Trustee at a rate of one New Share for each share of
  ESOP Preferred Stock (subject to adjustment). Primarily because of
  limitations imposed by the Internal Revenue Code, the ESOP consists of
  three major portions: (i) the Leveraged ESOP, the Non-Leveraged Qualified
  ESOP, and the Supplemental ESOP. Shares of ESOP Preferred Stock issued
  under the Leveraged ESOP and the Non-Leveraged Qualified ESOP will be held
  by the ESOP Trustee under the Qualified Trust. Under the Supplemental ESOP,
  shares will be credited as Book-Entry Shares when earned by employees, and
  will be issued to employees as New Shares, generally upon termination of
  employment. ALPA has the right to elect at any time, before or after the
  Effective Time, that the Supplemental ESOP be maintained by the actual
  issuance of Class 2 ESOP Preferred Stock to a non-qualified trust
  established under the Supplemental Plan. In general, the Plan of
  Recapitalization is designed to maximize the number of shares of ESOP
  Preferred Stock that may be sold to the Qualified Trust. However, because
  of certain limitations imposed by the Internal Revenue Code, a portion of
  the equity interest to be obtained by the ESOP Trustee may not be sold to
  the Qualified Trust. The Class 1 ESOP Preferred Stock contains a fixed
  dividend feature which is intended to maximize the number of shares of
  Class 1 ESOP Preferred Stock that may be sold to the Qualified Trust
  consistent with the applicable provisions of the Internal Revenue Code. To
  the extent the Qualified Trust is unable to purchase the Class 1 ESOP
  Preferred Stock, Class 2 ESOP Preferred Stock will be issued, to the extent
  permitted by the limitations of the Internal Revenue Code, to the ESOP
  Trustee pursuant to the Non-Leveraged Qualified ESOP. Class 2 ESOP
  Preferred Stock will not contain a fixed dividend. To the extent that Class
  2 ESOP Preferred Stock cannot be issued to the ESOP Trustee because of the
  limitations of the Internal Revenue Code, the Company will credit Book-
  Entry Shares to accounts established for the employees.     
   
(5) To record the issuance at par of one share of Class P Voting Preferred
    Stock, one share of Class M Voting Preferred Stock, and one share of Class
    S Voting Preferred Stock to the Qualified ESOP. The remaining Voting
    Preferred Stock will be issued when it is contributed to the Qualified ESOP
    and the Supplemental ESOP. The Class P Voting Preferred Stock, the Class M
    Voting Preferred Stock and the Class S Voting Preferred Stock, which are
    referred to collectively as the Voting Preferred Stock, represent and
    permit, in connection with the establishment of the ESOPs, the exercise of
    the voting power representing 55% (which under certain circumstances may be
    increased to up to 63%) of the voting power of the Company. See
    "DESCRIPTION OF SECURITIES--The Voting Preferred Stock." The Restated
    Certificate provides that upon the conversion of all the ESOP Preferred
    Stock into New Shares, each share of Voting Preferred Stock will be
    converted into one ten-thousandth of a New Share.     
   
(6) To account for the cashless exercise of options in the event of the
    Recapitalization. (Amount of the entry is based on an assumed Old Share
    price at the Effective Time of approximately $131 per share.)     
   
(7) Represents the offset to entries (2), (3), (6), (8), (9) and (11).     
   
(8) To record the vesting of the unvested restricted stock as a result of the
    Recapitalization.

    Effective Time.     
   
(10) Does not reflect the issuance of four shares of Class I Preferred Stock,
     one share of Class Pilot MEC Preferred Stock, one share of Class IAM
     Preferred Stock, and three shares of Class SAM Preferred Stock. These
     stocks have a $.01 par value and nominal economic value. The Class I
     Preferred Stock will be issued to the Independent Directors and will have
     the power to elect such directors to the Board. The Class Pilot MEC
     Preferred Stock will be issued to the ALPA-MEC and will have the power to
     elect the ALPA Director. The Class IAM Preferred Stock will be issued to
     the IAM or its designee and will have the power to elect the IAM Director.
     The Class SAM Preferred Stock will be issued to the Salaried and
     Management Director and to the senior executive at United who has primary
     responsibility for human resources and will have the power to elect the
     Salaried and Management Director. Such classes of stock are referred to
     collectively as the Director Preferred Stock. See "DESCRIPTION OF
     SECURITIES--The Director Preferred Stock." Upon the occurrence of an
     Uninstructed Trustee Action (as defined below), the Class Pilot MEC
     Preferred Stock will succeed to the voting power previously held by the
     Class P Preferred Stock, the Class IAM Preferred Stock will succeed to the
     voting power previously held by the Class M Preferred Stock and the Class
     SAM Preferred Stock will succeed to the voting power previously held by
     the Class S Preferred Stock. See "DESCRIPTION OF SECURITIES--The Director
     Preferred Stock--Uninstructed Trustee Actions."     
   
(11) To reverse $19 million of transaction fees and expenses recorded during
     the first quarter of 1994 because these expenses are included in entry
     (2).     
   
(12) The number of New Shares issued on a pro forma basis is based on Fully
     Diluted Old Shares assuming the Convertible Company Securities do not
     convert. See "The PLAN OF RECAPITALIZATION--Terms and Conditions--
     General."     
   
              UNITED AIR LINES, INC. AND SUBSIDIARY COMPANIES     
   
  The following statement sets forth the unaudited consolidated financial
position of United and its subsidiaries at March 31, 1994 and the unaudited pro
forma consolidated financial position of United and its subsidiaries after
giving effect to the Recapitalization and the Offerings, and the payment of
fees and expenses incurred in connection with the Recapitalization. The
statement should be read in conjunction with the selected consolidated
financial and operating information, the unaudited pro forma financial
information and the respective related notes thereto appearing elsewhere
herein. See "SELECTED CONSOLIDATED FINANCIAL AND OPERATING INFORMATION--United
Air Lines, Inc. and Subsidiary Companies" and "UNAUDITED PRO FORMA FINANCIAL
INFORMATION--United Air Lines, Inc. and Subsidiary Companies." In addition, the
statement should be read in conjunction with United's Annual Report on Form 10-
K for the year ended December 31, 1993 and Quarterly Report on Form 10-Q for
the quarter ended March 31, 1994, which are included elsewhere in this Proxy
Statement/Prospectus and which include United's Consolidated Financial
Statements, the related notes thereto and "Management's Discussion and Analysis
of Financial Condition and Results of Operations."     
   
  The pro forma statement assumes the Recapitalization is not accounted for as
an acquisition or merger and, accordingly, United's assets and liabilities have
not been revalued.     
       
       
       
   
  The ESOPs are being accounted for in accordance with the American Institute
of Certified Public Accountants Statement of Position 93-6, "Employers'
Accounting for Employee Stock Ownership Plans" ("SOP"). For the Leveraged ESOP,
the Company will issue Class 1 ESOP Preferred Stock through seven ESOP Tranches
beginning at the Effective Time, thirteen months after the Effective Time,
annually thereafter for four years with a final ESOP Tranche on January 1,
2000. As the shares are issued to the Leveraged ESOP, United will report the
issuance of shares as a credit to ESOP capital based on the fair value of the
    
                                     xxxiii
<PAGE>
 
   
stock when it occurs and report a corresponding charge to unearned ESOP
Preferred Stock. As shares of Class 1 ESOP Preferred are earned or committed to
be released, compensation expense will be recognized equal to the average fair
value of the shares committed to be released with a corresponding credit to
unearned ESOP Preferred Stock. Any differences between the fair value of the
shares committed to be released and the cost of the shares to the ESOP will be
charged or credited to ESOP capital. For the Non-Leveraged Qualified ESOP and
the Supplemental ESOP, the shares of Class 2 ESOP Preferred Stock will be
recorded as the shares are committed to be contributed to the ESOP, with the
offsetting entry to compensation expense. Compensation expense will be recorded
based on the fair value of the shares committed to be contributed to the ESOP,
in accordance with the SOP. The unearned ESOP Preferred Stock, ESOP capital and
employee stock ownership accounting charge will be recorded on United's books
since participants in the ESOP are employees of United.

                UNITED AIR LINES, INC. AND SUBSIDIARY COMPANIES
         
      NOTES TO PRO FORMA STATEMENT OF CONSOLIDATED FINANCIAL POSITION     
       
(1) To record the cash impact of the estimated fees and transaction expenses,
    including expenses for United, ALPA and the IAM, severance payments to
    terminated officers and flight kitchen employees, and payments relating to
    the employment agreement with Mr. Greenwald.
 
(2) To record the tax effects relating to nonrecurring charges recognized as a
    result of the transaction.
   
(3) To record the offering of $382.5 million of Series A Debentures and $382.5
    million of Series B Debentures and to record the distribution of proceeds
    to UAL. The Debentures are being recorded at their face amount based on the
    assumption that they are being priced to trade at par, less the
    underwriting discount of $7 million. The actual rate on the Debentures will
    be reset prior to the Effective Time and the Debentures are subject to a
    maximum interest rate of 112.5 basis points above the Initial Pricing. The
    underwriting agreements for the Offerings are expected to provide that if
    the offering is consummated, the interest rate may be adjusted in order for
    the Debentures to be sold at or close to par, in which case the principal
    amount of the Debentures will be reduced so that the annual interest
    expense will not exceed the stated maximum which was calculated based upon
    the rate cap. If the offering is not consummated and the interest rate
    exceeds the cap, the Debentures will be recorded at a discount.     
   
(4) To record the ESOP capital as a result of the initial issuance of shares of
    UAL's Class 1 ESOP Preferred Stock to the Qualified Trust for an aggregate
    purchase price of $228 million and to record the related charge to unearned
    ESOP Preferred Stock. The $228 million was determined based on (i)
    1,899,059 shares of Class 1 ESOP Preferred Stock expected to be issued in
    the first ESOP Tranche as of the Effective Time and (ii) an assumed
    purchase price of $120 per share. UAL and the Unions may, prior to the
    Effective Time, agree to increase or decrease the number of shares of Class
    1 ESOP Preferred Stock sold at the Effective Time. The agreement with the
    ESOP Trustee provides that the number of shares of Class 1 ESOP Preferred
    Stock sold at the Effective Time shall be no more than 2,088,965 and no
    fewer than 1,709,153. The actual price per share for the first ESOP Tranche
    will be 1.38 times the average price of a New Share at the Effective Time.
    Thus, the ultimate amount recorded at the Effective Time will differ from
    the pro forma adjustment in order to reflect the actual number of shares
    issued and the average closing price of the New Shares.     
      
   Six additional ESOP Tranches will be issued to the Leveraged ESOP during the
   69 months subsequent to the Effective Time, with the total shares of Class 1
   ESOP Preferred Stock issued in the seven ESOP Tranches aggregating
   approximately 14,000,000 shares (subject to increase, see "THE PLAN OF
   RECAPITALIZATION--Establishment of ESOPs--Additional Shares). The price for
   the subsequent ESOP Tranches will be as agreed between the Company and the
   ESOP Trustee at the time of each sale. As the subsequent ESOP Tranches are
   issued, the shares will be reported as a credit to additional capital
   invested based on the fair value of the stock when such issuances occur with
   a corresponding charge to "Unearned ESOP Preferred Stock."     
      
   The Unearned ESOP Preferred Stock recorded in the pro forma adjustment
   together with the Unearned ESOP Preferred Stock recorded from subsequent
   ESOP Tranches will be recognized as compensation expense over the
   approximately six year investment period as the shares are committed to be
   released. The difference between the compensation expense recorded, which is
   based on the fair value of the stock during an accounting period, and the
   initial recorded cost of the unearned ESOP Preferred Stock will be recorded
   to ESOP capital.     
      
   ESOP capital will also be recorded over the six year investment period as
   the shares of UAL's Class 2 ESOP Preferred Stock are committed to be
   contributed to the Non-Leveraged Qualified ESOP and credited to employees
   pursuant to the Supplemental ESOP with the offsetting entry being to
   compensation expense. The number of shares of Class 2 ESOP Preferred Stock
   that will be issued will be equal to 17,675,345 less the number of shares of
   Class 1 ESOP Preferred Stock that will be sold to the Qualified ESOP.

(5) To account for the cashless exercise of options in the event of the
    Recapitalization. (Amount of the entry is based on an assumed Old Share
    price at the Effective Time of approximately $131 per share.)     
 
(6) To record 25,000 restricted shares to Mr. Greenwald that will vest at the
    Effective Time.

(9) To reverse $19 million of transaction fees and expenses recorded during the
    first quarter of 1994 because these expenses are included in entry (1).

(a) In the first quarter of 1994, United began recording certain air
    transportation price adjustments, which were previously recorded as
    commission expense, as adjustments to revenue. Operating revenues and
    certain operating statistics for periods prior to 1994 have been adjusted
    to conform with the current presentation.     
   
(b) The Pro Forma Statement of Consolidated Financial Position assumes the
    transaction occurred at March 31, 1994. Therefore, pro forma information at
    December 31, 1993 is not applicable.     
       
   
(c) Earnings were inadequate to cover both fixed charges and fixed charges and
    preferred stock dividends by $98 million in 1993, by $748 million in 1992
    and by $599 million in 1991. On a pro forma basis, earnings were inadequate
    to cover fixed charges by $109 million in 1993.     
   
(d) Earnings were inadequate to cover both fixed charges and fixed charges and
    preferred stock dividends by $118 million and $224 million for the three
    month periods ended March 31, 1994 and 1993, respectively. On a pro forma
    basis earnings were inadequate to cover fixed charges by $97 million for
    the three months ended March 31, 1994.     
       
       
   
(e) The loss from operations includes an ESOP accounting charge which is
    dependent on the fair market value of the ESOP Preferred Stock during the
    period. The pro forma amount is based on an assumed fair value of $120 per
    share. See note 4 to the Pro Forma Condensed Statement of Consolidated
    Operations for both the year ended December 31, 1993 and the three months
    ended March 31, 1994 for the effects of different fair value assumptions on
    the ESOP accounting charge.

(a) In the first quarter of 1994, United began recording certain air
    transportation price adjustments, which were previously recorded as
    commission expense, as adjustments to revenue. Operating revenues and
    certain operating statistics for periods prior to 1994 have been adjusted
    to conform with the current presentation.     
   
(b) The Pro Forma Statement of Consolidated Financial Position assumes the
    transaction occurred at March 31, 1994. Therefore, pro forma information at
    December 31, 1993 is not applicable.     
   
(c) Earnings were inadequate to cover fixed charges by $77 million in 1993, by
    $694 million in 1992 and by $604 million in 1991. On a pro forma basis,
    earnings were inadequate to cover fixed charges by $63 million in 1993.
        
   
(d) Earnings were inadequate to cover fixed charges by $130 million and $211
    million for the three month periods ended March 31, 1994 and 1993,
    respectively. On a pro forma basis, earnings were inadequate to cover fixed
    charges by $102 million for the three months ended March 31, 1994.     
   
(e) The loss from operations includes an ESOP accounting charge which is
    dependent on the fair market value of the ESOP Preferred Stock during the
    period. The pro forma amount is based on an assumed fair value of $120 per
    share. See Note 4 to the Pro Forma Condensed Statement of Consolidated
    Operations for both the year ended December 31, 1993 and the three months
    ended March 31, 1994 for the effects of different fair value assumptions on
    the ESOP accounting charge.

  Contemporaneously with this solicitation, United Air Lines, Inc., a Delaware
corporation and a wholly-owned subsidiary of the Company ("United"), is
offering for sale $382,500,000 principal amount of its Series A Debentures due
2004 (the "Series A Debentures") and $382,500,000 principal amount of its
Series B Debentures due 2014 (the "Series B Debentures") (the "United Debt
Offering") and the Company is offering for sale 30,600,000 depositary shares
(the "Depositary Preferred Shares") representing interests in $765,000,000
aggregate liquidation preference of Series B Preferred Stock, without par
value, of the Company (the "Public Preferred Stock") (the "UAL Preferred
Offering" and, together with the United Debt Offering, the "Offerings"). If
the Offerings are consummated, the proceeds thereof will be used to fund a
portion of the cash payment to be made to holders of Old Shares pursuant to
the Recapitalization. The Offerings are conditioned on, and subject to, the
consummation of the Recapitalization. In addition, each Offering is
conditioned on, and subject to, the consummation of the other Offering. The
Recapitalization is not conditioned on, or subject to, the consummation of
either the United Debt Offering or the UAL Preferred Offering. If the
Offerings are consummated, it is expected that they will be consummated at or
immediately prior to the Effective Time (as defined below).     
   
  The Plan of Recapitalization provides, among other things, that the Old
Shares will be reclassified. As a result of the reclassification, each Old
Share outstanding at the consummation of the Recapitalization (the "Effective
Time"), including each share of restricted stock issued pursuant to the 1988
Restricted Stock Plan (which will vest upon the Effective Time if not vested
prior thereto), together with up to 1,000,000 Old Shares held by the Company
as treasury stock or owned by any wholly-owned subsidiary of the Company
immediately prior to the Effective Time, will be reclassified as follows:     
     
    (a) If the Offerings are consummated, upon the Effective Time, each
  outstanding Old Share will be reclassified as, and converted into, one-half
  (0.5) of a new share of common stock, par value $0.01 of the Company (the
  "New Shares") and one one-thousandth of a share of Series E Redeemable
  Preferred Stock, without par value, of the Company (the "Series E
  Redeemable Preferred Stock"), which will be redeemed immediately after
  issuance for cash in an amount equal to the sum of (a) $25.80, (b) the
  proceeds (without deducting the underwriting discount or other costs) from
  the sale by United of $15.55 principal amount of Series A Debentures and
  $15.55 principal amount of Series B Debentures pursuant to the United Debt
  Offering and (c) the proceeds (without deducting the underwriting discount
  or other costs) from the sale of 1.244 Depositary Preferred Shares
  representing interests in $31.10 liquidation value of Public Preferred
  Stock pursuant to the UAL Preferred Offering.     
     
    (b) If the Offerings are not consummated, upon the Effective Time, each
  outstanding Old Share will be reclassified as, and converted into, one-half
  (0.5) of a New Share and one one-thousandth of a share of Series D
  Redeemable Preferred Stock, without par value, of the Company (the "Series
  D Redeemable Preferred Stock") (the Series E Redeemable Preferred Stock and
  the Series D Redeemable Preferred Stock are sometimes referred to herein as
  the "Redeemable Preferred Stock"), which will be redeemed immediately after
  issuance for (a) $25.80 in cash, (b) $15.55 principal amount of Series A
  Debentures, (c) $15.55 principal amount of Series B Debentures and (d)
  1.244 Depositary Preferred Shares representing interests in $31.10 in
  liquidation preference of the Public Preferred Stock.     
 
                                       2
<PAGE>

   
  Under various circumstances, the value of the consideration to be received
by stockholders could be less than the stated face amount or liquidation
preference of the Debentures or Depositary Preferred Shares.     
   
  The New Shares and cash distributed in respect of Old Shares if the
Offerings are consummated are referred to herein as the "Proceeds
Recapitalization Consideration." The New Shares, cash, Debentures and
Depositary Shares distributed in respect of Old Shares if the Offerings are
not consummated are referred to herein as the "Mixed Recapitalization
Consideration." The Proceeds Recapitalization Consideration and the Mixed
Recapitalization Consideration are each sometimes referred to herein as the
"Recapitalization Consideration."     
   
  The terms of the Debentures, the Public Preferred Stock and the Depositary
Preferred Shares are described under "DESCRIPTION OF SECURITIES--The
Debentures," "--The Public Preferred Stock" and "--The Depositary Preferred
Shares." Under the Plan of Recapitalization, the interest rate on the Series A
Debentures has been fixed provisionally at 9.00%, the interest rate on the
Series B Debentures has been fixed provisionally at 9.70% and the dividend
rate on the Public Preferred Stock has been fixed provisionally at 10.25%.
Under the Plan of Recapitalization, the interest rates on the Debentures and
the dividend rate on the Public Preferred Stock will be adjusted not less than
five nor more than ten days before the date of the Meeting (the "Announcement
Date") to rates (which in each case, if there is an upward adjustment, may not
be more than 112.5 basis points (i.e., 1.125 percentage points) higher than
the respective provisional rates, but which in the case of a downward
adjustment are not limited) that, in the opinion of certain financial advisors
to the Company and the Unions and in the case of a deadlock, based on a
process involving a third financial advisor identified by the Company and the
Unions, would permit the Debentures and the Depositary Preferred Shares
representing interests in the Public Preferred Stock to trade at par on such
date on a fully distributed basis. See "THE PLAN OF RECAPITALIZATION--Terms
and Conditions--Pricing the Securities."     
   
  The underwriting agreements relating to the Offerings will provide that if
the Offerings are consummated, the interest rates on the Debentures and the
dividend rate on the Preferred Stock may be adjusted (including in excess of
their respective caps) to permit the Debentures and the Depositary Preferred
Shares to be sold at or closer to par, but if that is done, the principal
amount of the series of Debentures affected or the number of Depositary
Preferred Shares representing interests in the Public Preferred Stock, as the
case may be, will be reduced so that the aggregate amount of interest payable
annually by United on the Debentures or the aggregate amount of dividends
payable annually by the Company on the Public Preferred Stock will not exceed
certain amounts calculated in reference to such caps. If the Offerings are not
consummated, the interest rates borne by the Debentures and the dividend rate
borne by the Public Preferred Stock will be subject to the caps. See "THE PLAN
OF RECAPITALIZATION--Terms and Conditions--Pricing the Securities."     
   
  Each share of Series A Convertible Preferred Stock of the Company ("Series A
Preferred Stock") and each of the Air Wis Services, Inc. 7 3/4% Convertible
Subordinated Debentures Due 2010 and the Air Wis Services, Inc. 8 1/2%
Convertible Subordinated Notes Due 1995 outstanding immediately prior to the
Effective Time (each, a "Convertible Company Security") will remain
outstanding, and each holder of any such Convertible Company Security will
have the right to receive, upon conversion thereof from and after the
Effective Time, the Recapitalization Consideration with respect to each Old
Share that such holder would have been entitled to receive had such holder
converted such Convertible Company Security in full immediately prior to the
Effective Time. If the Offerings are consummated, holders of Convertible
Company Securities who convert their securities after the Effective Time will
receive the Proceeds Recapitalization Consideration upon such conversion, and
if the Offerings are not consummated, they will receive the Mixed
Recapitalization Consideration upon such conversion.     
   
  At the Effective Time, each outstanding employee stock option of the Company
granted under the 1981 Stock Program or the Air Wis Services, Inc. 1987 Non-
Qualified Stock Option Plan will remain outstanding, each such option then
held by active employees and officers (including persons who were officers of
the Company or United as of July 1993) (collectively, the "Options") will
become fully vested and exercisable at     
 
                                       3
<PAGE>
 
   
the Effective Time and each such Option will thereafter represent the right to
receive, until the expiration thereof in accordance with its terms, in exchange
for the aggregate exercise price for such Option, the Recapitalization
Consideration with respect to each Old Share that such holder would have been
entitled to receive had such holder exercised such Option in full immediately
prior to the Effective Time. If the Offerings     
   
are consummated, holders of Options who exercise their Options after the
Effective Time will receive the Proceeds Recapitalization Consideration upon
such exercise, and if the Offerings are not consummated, they will receive the
Mixed Recapitalization Consideration upon such exercise.     
 
VOTING RIGHTS AND PROXY INFORMATION
   
  The Board of Directors of the Company has fixed the close of business on May
23, 1994 as the record date (the "Record Date") for determining which holders
of Old Shares are entitled to notice of and to vote at the Meeting.
Accordingly, only holders of record of Old Shares at the close of business on
the Record Date will be entitled to vote at the Meeting. At the close of
business on the Record Date, there were              Old Shares outstanding and
entitled to vote, held by 19,072 stockholders of record. As of the close of
business on the Record Date, there were also           Old Shares held as
treasury stock by the Company, which Old Shares will not be voted at the
Meeting. Holders of Series A Preferred Stock will not be entitled to vote at
the Meeting, although such holders may convert their shares of Series A
Preferred Stock into Old Shares prior to the Record Date and vote such Old
Shares at the Meeting.     
 
  Each holder of record of Old Shares on the Record Date is entitled to cast
one vote per Old Share, in person or by properly executed proxy, at the
Meeting. The presence in person or by properly executed proxy of the holders of
a majority of the outstanding Old Shares entitled to vote is necessary to
constitute a quorum at the Meeting.
   
  Under Delaware law, the affirmative vote of the holders of a majority of the
Old Shares outstanding on the Record Date will be required to approve and adopt
the Plan of Recapitalization and the Charter and Bylaw Amendments, the
affirmative vote of the holders of a plurality of Old Shares present in person
or represented by proxy at the Meeting will be required to elect each of the
directors and the affirmative vote of the holders of a majority of Old Shares
present in person or represented by proxy at the Meeting will be required to
approve or adopt each of the other matters identified in this Proxy
Statement/Prospectus as being presented to holders of Old Shares at the
Meeting. None of the votes described above requires the separate approval by a
majority of the shares held by the Company's unaffiliated stockholders. The
Company's directors (other than Dr. Brimmer) and executive officers, and their
affiliates, have sole or shared voting power and beneficial ownership with
respect to approximately 1.6 percent of the outstanding Old Shares, which they
intend to vote in favor of the Plan of Recapitalization and the Charter and
Bylaw Amendments. Accordingly, the affirmative vote of the holders of
approximately 48.4 percent of the outstanding Old Shares (other than directors
and executive officers and their affiliates) is required for approval of the
Plan of Recapitalization. Dr. Brimmer expects to vote his shares against the
Plan of Recapitalization and the Charter and Bylaw Amendments.     
 
  All Old Shares that are represented at the Meeting by properly executed
proxies received prior to or at the Meeting and not revoked will be voted at
the Meeting in accordance with the instructions indicated in such proxies. IF
NO INSTRUCTIONS ARE INDICATED, SUCH PROXIES WILL BE VOTED FOR APPROVAL OF THE
PLAN OF RECAPITALIZATION, THE CHARTER AND BYLAW AMENDMENTS, THE STOCK ISSUANCE,
THE AMENDMENT OF THE 1981 STOCK PROGRAM, THE AMENDMENT OF THE 1988 RESTRICTED
STOCK PLAN AND THE AMENDMENT OF THE INCENTIVE PLAN; FOR THE ELECTION OF FOUR
PUBLIC DIRECTORS AND FOR THE RATIFICATION OF ARTHUR ANDERSEN AND AGAINST THE
STOCKHOLDER PROPOSALS. The Board of Directors of the Company does not know of
any matters, other than as described in the Notice of Meeting attached to this
Proxy Statement/Prospectus, that are to come before the Meeting. IF A PROXY IS
GIVEN TO VOTE IN FAVOR OF THE PLAN OF RECAPITALIZATION, THE PERSONS NAMED IN
SUCH PROXY WILL HAVE AUTHORITY TO VOTE IN ACCORDANCE WITH THEIR
 
                                       4
<PAGE>
 
BEST JUDGMENT ON ANY OTHER MATTER THAT IS PROPERLY PRESENTED AT THE MEETING FOR
ACTION, INCLUDING WITHOUT LIMITATION, ANY PROPOSAL TO ADJOURN THE MEETING OR
OTHERWISE CONCERNING THE CONDUCT OF THE MEETING.
   
  Abstentions will have the effect of a vote against the Plan of
Recapitalization, the Charter and Bylaw Amendments and the other matters
presented for a vote of the stockholders (other than the election of
directors). With respect to abstentions, the Old Shares are considered present
at the Meeting. The abstentions are not, however, affirmative votes for the
matters presented for a vote and, therefore, they will have the same effect as
votes against any matter presented for a vote of the stockholders (other than
the election of directors). With respect to the election of directors,
abstentions and broker non-votes will be disregarded and will have no effect on
the outcome of the vote. Broker non-votes will have no effect on the outcome
and the vote on any of the matters presented for a vote of stockholders at the
Meeting, other than the Charter and Bylaw Amendments. With respect to the
Charter and Bylaw Amendments, broker non-votes are considered present and,
accordingly, will have the effect of a vote against the Charter and Bylaw
Amendments.     
 
  In the event that a quorum is not present at the time the Meeting is
convened, or if for any other reason the Company believes that additional time
should be allowed for the solicitation of proxies, the Company may adjourn the
Meeting with a vote of the stockholders then present. The persons named in the
enclosed form of proxy will vote any Old Shares for which they have voting
authority in favor of such adjournment.
   
  Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (i) filing
with the Secretary of the Company, before the polls are closed with respect to
the vote, a written notice of revocation bearing a later date than the proxy,
(ii) duly executing a subsequent proxy relating to the same Old Shares and
delivering it to the Secretary of the Company or (iii) attending the Meeting
and voting in person (although attendance at the Meeting will not in and of

                   BACKGROUND OF THE PLAN OF RECAPITALIZATION
 
  In the years following a 29-day strike by ALPA in 1985, relations between the
Company and its principal unions, ALPA, the IAM and the Association of Flight
Attendants ("AFA"), have often been discordant. During this period, a number of
significant events involving a potential change in corporate control or the
sale of substantial assets of the Company have occurred or were proposed, many
of which events involved the participation of one or more of the Company's
unions, including (i) an offer by ALPA to acquire United and the Company's
computerized reservation system for $4.5 billion in April 1987, (ii) a consent
solicitation by a group including Coniston Partners in May 1987, (iii) a
planned recapitalization, announced by the Company in May 1987, that would have
resulted in the Company's stockholders receiving $60 per share while retaining
their shares, (iv) the adoption in June 1987, following the resignation of
Richard J. Ferris as chairman of the Company, of a restructuring plan involving
the sale of the Hertz Company, Westin Hotel Company and Hilton International
Co. and a distribution of cash, which led to such sales through a tender
 
                                       5

offer by the Company for its own shares which was completed in March 1988, (v)
a proposal by a pilot-organized entity to acquire the Company for $110 per
share in May 1988, (vi) a proposal from Marvin Davis to acquire the Company for
$240 per share in August 1989, (vii) the entry into a merger agreement with
Airline Acquisition Corp. (an entity which was intended to be owned 75% by
employee stock ownership plans for the benefit of the Company's employees, 15%
by British Airways and 10% by the Company's senior management) providing for
consideration of $300 per share, which agreement was entered into in September
1989 and thereafter failed due to an inability to obtain necessary financing,
and (viii) the entry into a merger agreement with United Employee Acquisition
Corp. (an entity formed by ALPA, the IAM and AFA) providing for consideration
of $155 per share in cash, $35 per share in Company debt securities and $13 per
share in debt securities of Covia Corp., which agreement was entered into in
April 1990 and terminated in October 1990 due to an inability to obtain
necessary financing following Iraq's invasion of Kuwait.     
 
  During this period, earnings per share from continuing operations, helped by
both the strength of the global economy and operating improvements undertaken
by the Company, grew from a loss of $3.43 in 1985 to positive earnings of
$20.20 in 1988 and $14.96 in 1989. This improving earnings posture came to a
dramatic halt in 1990 when Iraq's invasion of Kuwait sent fuel prices
skyrocketing while simultaneously dampening consumer demand for air travel.
These events, combined with the downturn in the global economy, led to
disappointing earnings per share of $4.33 in 1990 and a per share loss of
$14.31 in 1991.
 
  In recent years, including during 1992, the Company has noted the emergence
of a fundamental shift in consumer behavior, with an increased focus on the
price/value relationship. Travel preference (of both business and leisure
travellers) has continued to shift to low-cost travel as provided by carriers
such as Southwest Airlines, Inc. ("Southwest"), Morris Air and Reno Air. The
Company believed that this trend was long-term and would continue even if the
weak economic conditions of the early 1990s improved. The Company determined
that its ability to be competitive in such an environment required a
substantial reduction of its operating costs.
 
  Thus, on January 6, 1993, the Company, while recognizing that it had put in
place progressively leaner operating budgets over the prior few years,
nevertheless announced a further $400 million cost reduction program, including
the subcontracting of skycaps and certain janitorial services and the furlough
of 2,800 employees. Additionally, the Company restructured its fleet plan and
aircraft purchase commitments, cancelling firm orders for 49 Boeing aircraft,
deferring acceptance of 14 Airbus aircraft and accelerating the retirement of
25 older aircraft. The net effect of these changes was to reduce the Company's
planned capital spending through 1996 by over $6.2 billion and reduce the size
of the planned 1996 year-end fleet size by over 85 aircraft.
 
  The Company determined that even with these changes it would be necessary to
reduce its single largest expense, labor costs, to be competitive in the
changed environment of the 1990s. Thus, in addition to the subcontracting,
furloughs and the implementation of a 5% salary reduction program for certain
management employees, the Company requested concessions from its three
principal unions on January 14, 1993. AFA rejected such request on January 14,
1993 and the IAM rejected such request on January 19, 1993. ALPA indicated that
it desired to conduct a financial review of the Company.
   
  In light of the unwillingness of the Company's unions to participate in the
Company's cost-cutting efforts, the Company thereafter announced its intention
to undertake various other cost-cutting actions, including selling its flight
kitchens, subcontracting certain ground services, opening a flight attendant
domicile in Taiwan and evaluating the sale of the Denver flight training
center. CS First Boston Corporation ("CS First Boston") was retained February
12, 1993 to assist the Company in connection with the evaluation of a sale of
the United States flight kitchens. The Company also discussed the possibility
of subcontracting its jet repair work, selling its jet engine overhaul
maintenance facility in San Francisco, subcontracting its components business
and ground equipment overhaul business, and subcontracting its line maintenance
work, building maintenance work, and computer terminal technician work.

  In March, 1993, Booz . Allen & Hamilton ("BAH") was engaged by the Company to
provide a description of, and outlook for, the U.S. airline industry and
United. The assessment focused on the domestic airline industry as represented
by the thirteen leading carriers, who together represent 99% of the U.S.
airline industry's capacity. At a meeting of the Company's Board of Directors
(the "Board") held on April 28, 1993, BAH presented a report to the Board. In
its report, BAH noted "the U.S. airline industry has historically
underperformed, particularly since deregulation when overall financial returns,
in the aggregate, have been negative. Despite this poor performance, the
industry expanded rapidly after deregulation. However, to fill the rapidly
expanding capacity, the industry had to drop prices almost continuously.
Unfortunately, for a significant portion of the post-deregulation period--most
notable in the last three years--the industry has been unable to reduce costs
as rapidly as prices, which has led to significant industry-wide losses." The
report noted that it seemed unlikely that carriers such as United could achieve
sufficient cost reduction without a major restructuring. The report concluded
that United had to respond to major industry imperatives by reducing
competitive intensity, through redeploying capacity into core segments and
reducing costs to narrow the gap with its principal low-cost competitors. BAH
advised that to redeploy capacity to defensible segments, United should (i)
identify core capabilities as a basis for market advantage, (ii) focus product,
capacity and resource investments into specific core areas to capitalize on
those advantages, (iii) form partnerships/alliances to serve complementary
segments and (iv) withdraw from non-core activities. In order to reduce its
cost gap, United should (i) reduce controllable costs wherever possible, (ii)
work with labor to achieve wage reductions and productivity improvements and
(iii) pursue alternatives for radical restructuring and product redesign.     
 
  In a further presentation to the Board on June 24, 1993, BAH indicated that,
in the absence of labor cooperation, the Company had four options: (i)
restructure and downsize to focus on those markets where United could be
profitable in the long term, (ii) restructure and grow to create a stronger
domestic and international competitive position, (iii) return value to
stockholders by monetizing flying assets, services and/or other hard assets and
(iv) sell the airline in whole or in parts.
 
  On April 19, 1993, the Board received a letter from the United Airlines Union
Coalition (the "Coalition"), a group then composed of ALPA, the IAM and AFA,
expressing concern over asset sales and extensive restructuring. In response,
the Company sent a letter to the Coalition inviting a "shared solution" to the
Company's need to reduce operating costs. On June 2, 1993, Mr. Stephen M. Wolf,
Chairman of the Company, and Mr. Paul George, Senior Vice President--Human
Resources of United, met with Captain Roger D. Hall, Chairman, ALPA-MEC, Ms.
Diane Tucker, then President of the UAL/AFA Master Executive Council, and Mr.
Ken Thiede, President and General Chairman of IAM-District 141. At such
meeting, the Coalition indicated it was working on such a "shared solution". At
the time, the Company was engaged in discussions with potential purchasers of
its United States flight kitchens and final bids were due on July 20, 1993. The
Company agreed to defer any major restructuring action until July 19, 1993 and
requested that the Coalition submit a proposal by that time.
 
 July 16 Proposal
 
  On July 16, 1993, the Board received a letter from the Coalition (the
"Coalition July 16 Proposal") that stated that the Coalition's participation in
a cooperative restructuring was predicated on (i) employee investments by ALPA,
the IAM, AFA and United's salaried and management employees that would be
intended to produce an aggregate of $3.345 billion in employee cost savings
over five years, (ii) joint development over a 12-18 month period of a plan
intended to meet the competitive challenges facing United and projected to
provide at least $100 million in additional operating income in 1995, $200
million in 1996 and $300 million in 1997 and each year thereafter, (iii)
contribution of a substantial majority of the Company's common equity to a
trust or trusts for the benefit of the Company's employees, (iv) a
recapitalization of the Company (without additional external financing) in
which the existing stockholders would receive a substantial minority of the
Company's common stock and other consideration, (v) a balanced corporate
governance structure, (vi) a restructuring that was not dependent on third
parties (i.e., that did not require bank financing, a financial partner or a
strategic partner), (vii) a restructured Company that
 
                                       7
<PAGE>
 
maintained a substantial cash balance, (viii) negotiation of collective
bargaining provisions intended to protect the job security and work
opportunities of United's employees and (ix) preservation of the status quo
during negotiation of the proposal. The Coalition July 16 Proposal emphasized
that such points were "all essential elements of the restructuring" and
"available only in the context of a restructuring that meets the other
characteristics outlined above."
 
  On July 20, 1993, the Company retained CS First Boston to assist it in its
evaluation of the Coalition program. On July 21, 1993, the Coalition publicly
confirmed that it had provided "several concepts" to the Company with respect
thereto. On the same day, the Company publicly confirmed it was in
communication with the Coalition regarding the concepts provided to the Company
by the Coalition. Thereafter, representatives of the Company and the Coalition
commenced a series of meetings to discuss the Coalition program.
 
 August 5 Board Meeting
 
  On August 5, 1993, the Board held a meeting at which it considered a
presentation by BAH and members of Company management concerning ways to
improve the Company's profitability and provide stockholder value, with
specific focus on establishment of one or more domestic short-haul carriers
which would be owned independently of the Company and United and which would
virtually eliminate short-haul flying by United, along with other fundamental
alterations of the Company's business and structure (the "Fundamental
Restructuring Plan"). The Board also received a report on the status of
discussions with the Coalition. The Board discussed the alternative of
proceeding with the Fundamental Restructuring Plan and declining participation
in the program outlined in the Coalition July 16 Proposal, the alternative of
proceeding with the Coalition program and deemphasizing the Fundamental
Restructuring Plan and the alternative of proceeding to develop both the
Coalition program and the Fundamental Restructuring Plan. The Board,
recognizing that the Coalition was offering very substantial concessions but
that significant structural matters limited the ability to provide value to
stockholders, determined both to work with the Coalition and to develop
additional details of the Coalition July 16 Proposal. The Board concluded that
a Coalition proposal should be considered only in light of, among other things,
its valuation compared to the going concern value of the Company not taking
into account any restructuring plan and the value to stockholders of other
alternatives. The Board also instructed management to continue to explore the
alternatives discussed by BAH and to pursue the sale of the United States
flight kitchens.
 
  On August 10, Mr. Wolf and Mr. George met with Captain Hall, Mr. Kevin Lum,
who had replaced Ms. Tucker as President of the UAL/AFA Master Executive
Council, and Mr. Thiede and on August 11 the Company's representatives met with
the Coalition's representatives. At both meetings the Company conveyed the view
that, although the Company had not completed its valuation analysis, after
reviewing the program outlined by the Coalition, particularly the limitations
it imposed, the Company did not see how the program as outlined by the
Coalition permitted the Company to satisfy its key requirement in any
transaction involving the transfer of control: to deliver an appropriate
premium over market to the holders of Old Shares in a transaction that was fair
to such stockholders. At the same time, the Company expressed to the Coalition
the Board's willingness to discuss actively a transaction that involved
majority employee ownership, substantial corporate governance protection and
comprehensive job protection provisions, provided that it also satisfied the
Company's key requirement of providing substantial value to holders of Old
Shares. At the meeting among representatives, some specific approaches were
expressed as to possible areas of modifications to or enhancements of the
Coalition program in order to bridge what appeared to the Company to be a
substantial value gap. See "SPECIAL FACTORS--Certain Revenue and Earnings
Scenarios."
 
 August 25 Board Meeting
 
  In a meeting held on August 25, 1993, the Board reviewed the process that was
being followed and the steps that had been taken to obtain additional details
and evaluate the Coalition proposal. The Board then
 
                                       8
<PAGE>
 
reviewed in detail the various alternatives if the Company did not engage in a
transaction involving the sale of a majority of the equity to its employees,
including:
 
  . maintaining the "status quo" without undertaking extraordinary actions,
 
  . pursuing an alternative, referred to as the "enhanced status quo"
    alternative, whereby the Company would undertake certain extraordinary
    cost-cutting actions, including, for example, a sale of the flight
    kitchens, designed to enhance stockholder value over the "status quo"
    alternative without undertaking a major restructuring of the Company and
 
  . pursuing the Fundamental Restructuring Plan.
 
  In considering the "status quo" alternative, the Board considered as positive
factors the prospect of labor peace, the possibility that the aviation
environment might improve and the fact that this alternative preserved the
Company's opportunity to carry out a fallback strategy. It considered as
negative factors the fact that this alternative did not address the Company's
fundamental problems (especially the continued expansion of low-cost carriers),
and would result in continuing unsatisfactory financial performance, the loss
of a "window of opportunity" before labor contracts reopened, the failure to
provide sufficient incentive to the unions to lower costs and the prospect of a
declining price of the Old Shares.
 
  The Board viewed the positive aspects of pursuing the "enhanced status quo"
alternative as improved financial performance versus the "status quo"
alternative and the use of a "window of opportunity" before labor contracts
reopened. It viewed as negative factors the potential labor disruption in the
workplace, the lack of sufficient improvement of financial performance, the
failure to address the low-cost carrier problem and the possibility that United
would be subject to some adverse media/political attention, which factors would
potentially reduce the positive effects on the stock price.
 
  Because the "enhanced status quo" alternative was viewed as preferable to the
"status quo" alternative in all aspects except the potential for labor
disruption, the Board felt the "enhanced status quo" alternative was the
appropriate comparison when evaluating the Fundamental Restructuring Plan and
other alternatives.
 
  In considering the Fundamental Restructuring Plan, the Board noted that
pursuit of such plan would significantly improve financial performance if
successful, significantly improve stock price if successful, and take advantage
of the "window of opportunity" before labor contracts reopened. The Board also
noted that the ability of the Company to implement successfully this
alternative was uncertain and that this alternative had the potential to cause
extreme labor disruption in the workplace, to place severe limits on the
Company's ability to pursue an acceptable fallback strategy, to subject United
to extreme adverse media/political attention and to significantly depress the
Company's stock price if not successful.
 
  The Board also recognized that the Fundamental Restructuring Plan was likely
to be challenged by the Company's unions both in Federal court and in
arbitration under the Railway Labor Act. Such a challenge could involve issues
such as (i) whether the Fundamental Restructuring Plan violated statutory
prohibitions against interference with union rights and/or unilateral carrier
actions, (ii) whether the Fundamental Restructuring Plan violated provisions in
the ALPA or AFA agreements that prohibit the Company from controlling, managing
or holding any equity interest in another carrier, (iii) whether the
Fundamental Restructuring Plan violated a provision in the AFA agreement that
prohibits establishment of an "alter ego" carrier and (iv) whether the
Fundamental Restructuring Plan violated a clause in the ALPA agreement that
restricts marketing agreements with United Express carriers. The Board
recognized that resolution of these issues could delay or prevent
implementation of the Fundamental Restructuring Plan. The Board also considered
the corporate taxation aspects of the Fundamental Restructuring Plan, including
whether the creation of one or more new short-haul carrier entities would
qualify as a tax-free reorganization under Section 355 of the Internal Revenue
Code of 1986, as amended (the "Internal Revenue Code").
 
  Finally, the Board considered that a strategy involving a sale of a majority
of the Company's equity to employees would be expected to result in labor
peace, provide significant value to the stockholders, potentially
 
                                       9
<PAGE>
 
address the low-cost carrier problem and potentially preserve the Company's
opportunity to pursue a fallback strategy. The negative aspects of such a
strategy were determined to include the fact that, if not successful, the
Company would lose some of the "window of opportunity" and that the labor
unions might initiate a destructive public relations campaign coupled with
significant disruptive job action. The Board noted that such a strategy might
provide potentially less value to stockholders than a fully successful
Fundamental Restructuring Plan, although it would likely provide more value
than a failed Fundamental Restructuring Plan.
 
  At the August 25, 1993 Board meeting, CS First Boston made a presentation
summarizing its analyses of three alternatives to the Coalition program:
maintaining the "status quo", implementing the "enhanced status quo"
alternative (consisting of management actions that the Company believed would
increase labor force productivity or reduce labor costs but that would not
require a major restructuring) and implementing the Fundamental Restructuring
Plan, including an overview of the steps that would be required for
implementation of each. The presentation also included a preliminary valuation
analysis of the "enhanced status quo" alternative and the Fundamental
Restructuring Plan. In order to arrive at a range of values per share of the
Company assuming implementation of the "enhanced status quo" alternative, CS
First Boston used a discounted cash flow analysis to estimate the present value
of the future cash flows that the Company could be expected to produce over a
five-year period from 1994 through 1998 in accordance with management's
forecasts adjusted to reflect the cost reductions of the "enhanced status quo"
alternative. CS First Boston estimated a preliminary value range for the
Company, assuming the implementation of the "enhanced status quo" alternative,
by adding the present value of the five-year unleveraged free cash flows of the
Company under that scenario to the present value of the Company's 1998 terminal
value. The discount rates and terminal multiples reflected then-current market
conditions. This analysis resulted in a preliminary range of values per share
of the Company, assuming the implementation of the "enhanced status quo"
alternative, of from $150 to $180.
 
  CS First Boston's presentation included a preliminary range of values for the
Company assuming implementation of the Fundamental Restructuring Plan. CS First
Boston applied the same discounted cash flow methodology used in the "enhanced
status quo" case to the cash flows that the Company could be expected to
produce over the five-year period from 1994 through 1998 if the Fundamental
Restructuring Plan were adopted. This analysis resulted in a preliminary range
of values per share, if the Fundamental Restructuring Plan were successfully
implemented, of from $225 to $275. CS First Boston noted that this preliminary
range of values must be reduced by the expected costs of the transition to such
plan and the assumed costs of labor disruption related to the implementation of
the Fundamental Restructuring Plan, which were estimated to range from $22 to
$42 per share. After such reduction, this analysis resulted in a preliminary
range of values per share of the Company, if the Fundamental Restructuring Plan
were successfully implemented, of $183 to $253 per share. CS First Boston noted
that this range of values assumed that the transaction would not be taxable to
the Company or its stockholders and must be further reduced by the following
factors, which were not quantified: (i) the ownership share expected to be
retained by the new operators and accordingly not distributed to the Company's
stockholders, (ii) structural inefficiencies, (iii) national labor leadership
response, (iv) government reaction and (v) public relations risk.
 
  CS First Boston also presented a preliminary analysis of a range of values
for the Company if implementation of the Fundamental Restructuring Plan was
attempted by the Company, but was ultimately blocked as a result of legal
action, and the Company subsequently adopted the "enhanced status quo"
alternative described above. CS First Boston assumed for purposes of its
analysis that the Company would have absorbed the transition expenses and labor
disruption costs associated with the Fundamental Restructuring Plan during the
pendency of the legal action. Accordingly, this analysis resulted in a
preliminary range of values per share of the Company, if the "enhanced status
quo" alternative were adopted following an unsuccessful attempt to implement
the Fundamental Restructuring Plan, of from $108 to $158.
 
  For information relating to the qualifications of CS First Boston, the method
of its selection, the nature of, and purpose for, its analyses, the procedures
it followed in connection therewith and the compensation it has received or
will receive, see "SPECIAL FACTORS--Opinions of the Financial Advisors to the
Board."

  The Board then further discussed issues concerning the various alternatives,
including their potential impact on the Company and the factors influencing the
potential success of each alternative.
 
  At the conclusion of its deliberations, the Board determined that the Company
should identify for the Coalition a set of possible enhancements to the
Coalition program but at the same time management should proceed with the
development of various restructuring activities as and to the extent management
deemed appropriate.
 
  In a letter to the Coalition dated August 25, 1993, the Company stated that
since August 11, 1993, the Company and its financial advisors "had performed
further analysis which has provided the Company with a clearer view of value,
both as to the Company if no Coalition transaction occurs and as to the value
of the Coalition program as reflected in the July 16th letter. The Company's
analysis has confirmed that a substantial value gap exists between the
Coalition program and the inherent value of the Company."
 
  In the August 25th letter, the Company outlined an approach to enhance the
Coalition's program for a majority employee ownership transaction for
consideration by the Coalition. This approach involved the following components
to enhance the Coalition's proposed structure: (i) one or more trusts for the
benefit of the Company employees would acquire 50.1% of the economic and voting
power of the Company's equity, (ii) (a) employee investment as described in the
Coalition July 16 Proposal would be supplemented by additional employee
investment amounting to $120 million in year 1 and growing to $160 million in
year 8, (b) an extension of the duration of the employee investment period by
three years, (c) the entire investment would be by verifiable pay rate/defined
contribution reductions, unless the Company agreed to alternative achievable
work-rule changes of equal value, (d) there would be no "snap-backs" and
contracts would be amendable after 8 years pursuant to Section 6 of the Railway
Labor Act, (e) in each of years 6, 7 and 8 of the investment period, all
employees would be provided a general wage rate increase of 2% per year if the
Company achieved its earnings projections and there would be no other wage
rate, per diem, allowance/premium or benefit increases during the investment
period (other than step, longevity or comparable increases for non-contract
salaried and management employees or status/promotional increases) and (f) a
profit-sharing plan to provide potential for annual lump sum cash payments to
employees if corporate performance targets are met, (iii) contract revisions
allowing the establishment of a low-cost short-haul airline within United or
the Company would be made, (iv) collective bargaining terms designed to provide
reasonable job security provisions acceptable to the Company and to United's
employees, which would not impose additional costs on United, would be agreed
to, (v) upon consummation of the transaction, each existing Old Share would
receive one new share of common stock and $100 in additional consideration,
consisting of approximately $25 in cash and additional "cash equivalent value,"
consisting of approximately $37 in value of debt with specified terms and
approximately $37 in value of preferred stock with specified terms and (vi)
special governance provisions would be applicable to the "new company."
 
  The Company noted that the outlined approach was intended to provide a basis
for discussion and was not intended to be exhaustive and that the Company
"recognized that the [outlined] approach to enhancing the Coalition's program .
. . will require amplification, modification and amendment of various aspects
of the approach."
 
  On September 1, 1993, the Company delivered additional material to the
Coalition on the economics of an "airline-within-an-airline" then described as
"Friendship Express" (and subsequently referred to as "U2").
 
  On September 13, 1993, the Company announced that it had agreed to sell
certain of its United States flight kitchens to Dobbs International Services,
Inc. ("Dobbs") and Caterair International Corp. ("Caterair"). The Company also
stated that it retained the option to terminate such agreements at any time
prior to November 13, 1993.
   
  On September 30, 1993, AFA announced that it had "terminated its
participation in the negotiations" due to the Company's decision to open a
flight attendant domicile in Taiwan. The Company had previously delayed this
action on several occasions (despite the Company's belief that it would
meaningfully increase     
 
                                       11
<PAGE>
 
   
the Company's productivity) in order to permit AFA time to consider its
participation in the transaction. Following such withdrawal by AFA, the Company
continued to have discussions with representatives of ALPA and the IAM. All
references in this document to the "Coalition" or the "Unions" following
September 30, 1993 refer to ALPA and the IAM, but not AFA.     
 
  On November 4, 1993, in response to media reports on the status of its
discussions with the Coalition, the Company announced that no definitive
proposal had been presented to the Company by the Coalition. On November 5,
1993, the Company announced it had sent a letter to the IAM containing a
proposal whereby, among other things, the Company and the IAM would enter into
a new seven-year contract relating to United States flight kitchens, in lieu of
a sale thereof, that would reduce the Company's current catering expense.
 
  On November 6, 1993, the Coalition delivered a draft proposal to the Company
with respect to a transaction. On November 8, 1993, a representative of the
Company delivered a response to the Coalition that stated, among other things,
that such draft presented significant deficiencies in addition to reflecting a
substantial shortfall in the level of employee investment.
 
 November 11 Proposal
 
  During the evening of November 11, 1993, the Coalition delivered a formal
proposal to the Company (the "Coalition November 11 Proposal"). The Coalition
November 11 Proposal provided, among other things, for the acquisition by one
or more employee stock ownership plans of securities representing 60% of the
equity interest and voting power of the Company, and receipt by the Company's
existing stockholders of a package comprised of an aggregate of $650 million in
cash paid by the Company, $500 million of debentures of the Company, $750
million of preferred stock of the Company, and common stock representing 40% of
the equity of the Company. The Coalition November 11 Proposal also stated that
it would be immediately withdrawn in the event the Company sold the flight
kitchens.
 
  Under the Coalition November 11 Proposal, ALPA, the IAM and salaried and
management employees would make wage concessions which the Coalition valued at
$3.496 billion in nominal amount, or $2.874 billion in present value (at a 9%
discount rate). Under collective bargaining agreement modifications provided
for in such proposal, the Company would be permitted to establish a unit to
compete with low-cost carriers in the domestic short-haul market. The Coalition
indicated that it believed that the present value (at a 9% discount rate) of
this competitive capability was approximately $2.7 billion and valued its
proposal at $165.67 per Old Share. CS First Boston analyzed the Coalition
November 11 Proposal and, at a Board meeting held on November 12, 1993,
indicated to the Board that it had concluded that the Coalition November 11
Proposal was substantially deficient from the standpoint of providing adequate
value to the Company's stockholders. CS First Boston indicated that, although
it had not completed a full analysis, it had calculated the value of the
Coalition November 11 Proposal as approximately $140 per Old Share.
 
  The Company communicated such conclusion to the Coalition on November 12,
1993 and further responded with a written alternative which sought to provide
"appropriate value" to stockholders while enabling the Coalition to achieve its
goal of majority employee ownership. Among other things, the Company's
alternative extended the employee investment period by two years, required
health insurance contributions and reduced many new hire rates. On November 12,
1993, the Coalition rejected such alternative, stating that it was willing to
continue negotiations subject to certain conditions.
 
  Based upon the Coalition response, the Board thereafter determined that the
interests of the Company's stockholders would be best served by not exercising
the right United had to terminate the flight kitchen sale contracts prior to
November 13, 1993. The Company was then advised by the Coalition that the
Coalition November 11 Proposal was withdrawn.
 
  On November 12, 1993, the Company issued a press release describing the
events of November 11 and 12 described above and stated that it remained
willing to continue to hold discussions with its labor unions
 
                                       12

and still believed that a cooperative approach to solving a non-competitive
labor cost structure was in the best interests of all parties.
 
  On November 16, 1993, Mr. Wolf met in New York with Mr. Felix Rohatyn, a
general partner of Lazard Freres & Co. ("Lazard") and a member of the National
Commission to Ensure a Strong Competitive Airline Industry from June 1993
through September 1993, in order to explore the basis for renewed discussions
with the Company's labor unions. Thereafter, the Board authorized the retention
of Lazard. After the retention of Lazard, Lazard and CS First Boston contacted
advisors to the Coalition to see if a "firm basis for continued discussion" was
possible. On December 1, 1993, Company management and representatives met with
senior Coalition officials and discussed certain significant issues, including
a mechanism designed to help bridge the difference between the Company and the
Coalition of their respective valuations of the Company after giving effect to
the concessions.
 
  Thereafter, numerous meetings were held between representatives of the
Company and representatives of the Coalition to discuss elements of a possible
transaction.
 
 December 16 and 22 Board Meetings
   
  On December 16, 1993, the Board met to discuss the status of a revised
Coalition proposal (the "Revised Coalition Proposal"). The Revised Coalition
Proposal contemplated the acquisition by the employee trusts of a minimum of
53% of the common equity, subject to increase to up to 63% based on stock price
performance in the year after closing, a recapitalization in which the holders
of Old Shares would receive cash, debt and preferred stock valued at $88, and
$4.548 billion net present value of wage and benefits reductions and work-rule
changes relating to the Company's employees. In addition, the Revised Coalition
Proposal contained a mechanism for resolving differences between the Company
and the Coalition over the present value of the employee investment and the
"Competitive Action Plan" contained in the proposal. The Coalition believed
that the elements of the Revised Coalition Proposal provided a total market
value of $6.9 billion to the Company and its stockholders; applying the same
methodology used by the Coalition, the Company and its outside advisors
believed the elements of the Revised Coalition Proposal represented $5.2
billion in market value. To resolve this dispute, the Revised Coalition
Proposal contemplated an initial acquisition of 53% of the Company common
equity by trusts for the participating employees based on the Company's
valuation of the elements of the Revised Coalition Proposal at $5.2 billion.
However, the proposal also allowed the trusts for the participating employee
groups to obtain additional equity of the Company, up to 63% in total, if and
to the extent the average trading price of the New Shares over the initial year
following the Effective Time exceeded certain levels. At such meeting, the
Board reviewed, among other things, the amount and terms of the consideration
to be received by the public stockholders, the nature of the employee
concessions, other terms of a proposed Agreement in Principle (as defined
below) incorporating such Revised Coalition Proposal, including proposed
conditions, the impact of the proposed transaction on the Company's access to
financing, and other issues related to the structure of an employee stock
ownership plan, tax effects and earnings per share and other valuation effects.
During such meeting, representatives of both CS First Boston and Lazard
indicated that despite the publicity surrounding the proposed transaction, no
third party had indicated interest in acquiring the Company as an entirety and
noted that certain factors, including the state of the leveraged acquisition
market and the fundamental need to address cost factors, might be responsible
for the lack of third party acquisition interest. At the conclusion of such
meeting, the Board instructed the Company's representatives to continue to
negotiate the open issues in the proposed Agreement in Principle with a view
towards having a definitive proposal for presentation at a December 22, 1993
Board meeting.     
 
  On December 22, 1993, the Board met again to discuss the substantially
completed Agreement in Principle with respect to the Revised Coalition
Proposal. During such meeting, the Board reviewed, among other things, the
proposed corporate governance structure of the Company going forward, issues
related to management and employee reaction to a transaction and the related
transition, the alternatives available to the Company, including potential
labor disruption (including the effect on public perception and relations with
governmental authorities) if other alternatives were pursued, and the financial
terms of the Revised
 
                                       13
<PAGE>
 
Coalition Proposal. The Board discussed the requirement of the unions that Mr.
Wolf, Mr. John C. Pope, President, and Mr. Lawrence M. Nagin, Executive Vice
President--Corporate Affairs and General Counsel, retire at the Effective Time
as well as the fact that the majority of the Board would be replaced, and
extensively discussed issues relating to management of the Company following
the transaction.
 
  At the December 22, 1993 Board meeting, CS First Boston and Lazard gave an
overview of the Revised Coalition Proposal, including the improvements from the
Coalition's November 11 Proposal. CS First Boston and Lazard described how the
Revised Coalition Proposal would affect the Company's balance sheet. CS First
Boston and Lazard also described how the accounting rules applicable to "stock
based compensation" (which require that stock compensation expense for periodic
stock allocations be measured by the then-current market value of the shares at
the time of allocation) would apply to the share allocations in the employee
stock ownership plans contemplated under the Revised Coalition Proposal, the
resulting complexities to forecasting earnings per share and how the investment
community might analyze the situation. CS First Boston and Lazard discussed
certain valuation issues related to the debentures and the preferred stock
proposed to be issued in the Revised Coalition Proposal (including
redistribution issues and, in the case of the preferred stock, the limited
precedent for a security of the size of the contemplated issue). CS First
Boston and Lazard described the possible impact of the proposed transaction on
the Company's credit ratings and the cash flow impact of the proposed
transaction (including the fact that the proposed employee investment would
exceed the incremental fixed charges). CS First Boston and Lazard also
described the structure and operation of the stock ownership adjustment
mechanism contained in the Revised Coalition Proposal that would increase the
employee trusts stock ownership percentage from 53% to a maximum of 63% if the
Company's average closing stock price for one year after the Effective Time
exceeded specified levels.
 
  At such meeting, CS First Boston and Lazard indicated to the Board that, as
of such date, the consideration that would be received by holders of the Old
Shares in connection with the transaction contemplated by the proposed
Agreement in Principle, taken as a whole, was fair to such holders of Old
Shares from a financial point of view. See "SPECIAL FACTORS--Opinions of the
Financial Advisors to the Board." Following the presentations and discussions,
the Board voted (with Dr. Andrew Brimmer dissenting) to approve the Agreement
in Principle.
 
  The Agreement in Principle (the "Agreement in Principle") was executed on
December 22, 1993 and thereafter the parties commenced preparation of
definitive documentation. The Agreement in Principle provided for a
preservation of the "status quo," subject to ratification of the transaction by
the ALPA-MEC and the IAM membership occur by January 31, 1994 and an automatic
termination of the agreement to preserve the "status quo" if definitive
documentation was not completed by March 15, 1994. The IAM membership ratified
the transaction on January 26, 1994 and the ALPA-MEC ratified the transaction
on January 28, 1994.
 
 March 14 Board Meeting
   
  On March 14, 1994, the Board met to discuss the status of the proposed
definitive documentation. At such meeting, the Board received presentations
from management and counsel with respect to such status, including the
documentation, the differences between such documentation and the Agreement in
Principle (including, without limitation, the issuance of the Debentures by
United rather than the Company, the inclusion of other employee plans in
calculating the 20% "Sunset" threshold as described below in "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Sunset" and the provision for
payment of expenses of the Unions if the Plan of Recapitalization were
terminated because of another proposed transaction which was subsequently
consummated), the significant issues which remained unresolved (including,
without limitation, certain issues relating to indemnification of the IAM
relating to certain alleged claims by a former financial advisor, certain
issues relating to expenses of the Unions, certain issues relating to the
retention of a new CEO, certain issues related to the investment by Salaried
and Management Employees, the standard for Unions' review of the proxy, various
issues relating to the pricing     
 
                                       14
<PAGE>
 
   
of the Debentures and Public Preferred Stock and to the "treasury stock method"
of calculating the number of outstanding Old Shares, and certain issues related
to the ESOPs) and a discussion of the employee stock ownership plan
contemplated by the Agreement in Principle and its relationship to the
transaction, a presentation from American Appraisal Associates, Inc. ("American
Appraisal") with respect to issues of solvency and surplus under Delaware law
and a financial presentation from CS First Boston and Lazard.     
 
  Subsequent to such Board meeting, the parties continued to discuss various
issues, principally the salaried and management employees' contribution,
adjustments based on variances in share capitalization resulting from options
and convertible securities, the terms of the employment agreement for the new
chief executive officer and advisory fees. The Board had telephonic status
meetings on March 15 and March 16, where management advised the Board about
developments in the discussions with the Coalition.
 
 March 24 Board Meeting
   
  On March 24, 1994, the Board met telephonically to consider the definitive
Plan of Recapitalization. At such meeting, the Board discussed the proposed
transaction, focusing on issues that had either been resolved since the March
14 Board meeting or that remained unresolved, including the maximum final
pricing of the Debentures and the Public Preferred Stock, the adjustments
necessary to reflect the treasury stock method of calculating fully diluted
shares, the method of pricing a call feature on the Debentures, the nature of
the salaried and management employee concession package and a proposed
indemnity to the IAM against certain alleged claims asserted against the IAM by
a former financial advisor. In addition, the proposed Independent Directors (as
defined below) were identified. After discussion, the Board voted (with Dr.
Andrew Brimmer dissenting) to approve the definitive documentation for the
Recapitalization. Dr. Brimmer has indicated that he dissented from the vote
because under current economic conditions, he did not think there were
compelling reasons to effect such a transaction at this time. See "SPECIAL
FACTORS--Recommendation of the Board." On March 25, 1994, the initial Plan of
Recapitalization was executed by the Company, ALPA and the IAM (the "Initial
Plan of Recapitalization") reflecting the terms of the agreement in principle.
    
   
 Definitive Documentation Amendment     
   
  In light of prevailing market prices for the Old Shares in May 1994 and in
view of provisions in the Initial Plan of Recapitalization which enabled the
Coalition to assert that pricing conditions to consummation of the
Recapitalization relating to the purchase of ESOP Preferred Stock would not be
satisfied, the Coalition determined to approach the Company over possible
adjustments to the financial terms of the transaction in order to provide
greater certainty of completion of the Recapitalization. At the same time, the
Company felt that the Offerings would benefit the Company's stockholders as
part of the Recapitalization. In response to a proposal to modify the
definitive documentation from the Coalition, on May 20, 1994 the Board
determined to make an alternative proposal to the Coalition. The Coalition
accepted the Company's alternative proposal on May 22, 1994. On May  , 1994,
the Company and the Coalition executed an amendment to the definitive
documentation (the "Definitive Documentation Amendment") providing for, among
other things, (i) an increase in the percent of the common equity and voting
power initially to be acquired by the employee trusts from 53% to 55%; (ii) a
decrease in the range of average stock prices for the one year following the
Effective Time which would result in an increase to up to 63% in the percent of
common equity and voting power to be received by the employee trusts (prior to
the Definitive Documentation Amendment, the range had been $170.00-$178.44 per
share and it was decreased to $136.00-$149.10 per share (giving effect to the 1
for 2 common stock exchange ratio)) (see "THE PLAN OF RECAPITALIZATION--Terms
and Condition--Additional Shares"); (iii) the inclusion of the Offerings, and
(iv) revisions to the manner in which the ESOP Preferred Stock will be
purchased (see "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs"). As a
result of the Definitive Documentation Amendment, the purchase of the ESOP
Preferred Stock to occur at the Effective Time will be determined using a
market price-based formula and, accordingly, the Coalition is not entitled to
assert that the Recapitalization may not be consummated based on the market
price of the Old Shares or the expected market price of the New Shares.

                                SPECIAL FACTORS
 
CERTAIN COMPANY ANALYSES
 
  In connection with the consideration of the Recapitalization, United's
internal financial analysis group prepared an analysis (the "Company
Analysis") of the expected present value of the employee investments. The
Company Analysis estimated the net present value (using a 10% discount rate)
of such investment to be approximately $4.9 billion. The employee investments
are expected to be in the form of wage and benefit reductions, work-rule
changes and the startup of a new short-haul "airline-within-an-airline"
referred to herein as "U2" (See "--Implementation of the "Airline-Within-an-
Airline' (U2)").
   
  THE COMPANY ANALYSIS IS BASED UPON A VARIETY OF ASSUMPTIONS THAT MAY NOT BE
REALIZED AND ARE SUBJECT TO SIGNIFICANT UNCERTAINTIES AND CONTINGENCIES, MANY
OF WHICH ARE BEYOND THE COMPANY'S CONTROL. THE ACTUAL VALUE OF THE EMPLOYEE
INVESTMENTS MIGHT BE HIGHER OR LOWER THAN THE VALUE ESTIMATED IN THE COMPANY
ANALYSIS. THE COMPANY ANALYSIS HAS NOT BEEN UPDATED FOR PURPOSES OF THIS PROXY
STATEMENT/PROSPECTUS. NO ASSURANCE CAN BE GIVEN THAT THE ESTIMATED COST
SAVINGS IN THE COMPANY ANALYSIS WILL BE ACHIEVED OR THAT THE U2 OPERATION WILL
ACHIEVE THE POTENTIAL BENEFITS DESCRIBED BELOW. SEE "--CERTAIN RISK FACTORS--
INVESTMENT VALUES, FUTURE INVESTMENTS."     
 
  The employee investment relating to wage, benefit and work-rule
modifications was estimated to have a net present value in excess of $3.3
billion, including modifications associated with U2. While the current
contracts for both ALPA and the IAM become amendable in November 1994, the
value of this portion of the employee investment was not based on any
"projected" future wage rates, but rather using wage scales under the existing
contracts. Additionally, the Plan of Recapitalization specifically does not
guarantee any "snap-back" in wages or benefits at the end of the investment
period. Further, the valuation of the employee investment was reduced by the
potential for certain wage adjustments (that were not contractually
guaranteed) beginning in 1997. Despite the absence of "snap-back" provisions,
as these contracts will become amendable at that time, no valuation was made
of the benefit associated with the lack of a "snap-back" provision in the
post-investment period. In addition to the employee investment relating to
wage benefit and work-rule modifications, net benefits of U2 (excluding labor
savings) were estimated to have a net present value of approximately $1.6
billion.
 
                                ALPA INVESTMENT
 
  The ALPA investment consists of savings that are system-wide in nature and
that will continue for five years, nine months, as well as an additional
investment applicable solely to those pilots in the U2 operation and that will
remain in force for twelve years.
 
  The base investment includes the following features:
 
    . Reduction in hourly wages for all pilots of 15.7%
 
    . Reduction in the Company contribution to the defined contribution
      retirement plan from current 9% of wages (ordinary earnings,
      excluding expense reimbursements) to 1% of post-transaction (reduced)
      wages
 
    . No pay raise during first three years other than existing seniority
      and promotion increases
 
  An additional investment that should assist United in competing against low-
  cost carriers on short-haul routes includes:
 
    . Further reduction of approximately 7.1% in hourly wage rates for B737
      pilots in the U2 operation
 
    . Adjustments in work-rules for U2 pilots to increase productivity vis-
      a-vis the mainline United operation
 
  Partially offsetting these investments were changes to the following
  contract features:
 
    . Increased hourly rates for pilots flying the A320 aircraft
 
                                      16
<PAGE>
 
    . Potential increase in per diem and potential increase in wages in
      years 4 and 5 under an arbitrated settlement based on the Company's
      profitability, industry wage trends and wages at specified comparable
      carriers
 
  In addition, pilot benefits under the Company's defined benefit pension plan,
disability plan and life insurance plan will continue to be based on pre-
transaction "book" rates without regard to the 15.7% wage rate reduction.
 
                                 IAM INVESTMENT
 
  The IAM base investment will remain in force for six years. In lieu of
creating a separate U2 workforce, the IAM made additional system-wide work-rule
changes to improve productivity and competitiveness in all areas.
 
  The base investment includes the following features:
 
    . Reduction in hourly wage rates for all IAM employees of 9.7%
 
    . Elimination of the contractually provided May 1, 1994 wage increase
      of 5%
 
    . No pay raise during first three years other than existing seniority
      and promotion increases
 
  Additional work-rule changes that will remain in place for twelve years:
 
    . Elimination of the half-hour paid lunch period
 
    . Elimination of allowance for paid lunch period on overtime
 
    . Provide United with the ability to outsource up to 20% of maintenance
      work
 
  Partially offsetting these investments were:
 
    . Potential wage increase in years 4 and 5 under an arbitrated
      settlement based on the Company's profitability, industry wage trends
      and wages at specified comparable carriers
 
    . Improved severance package for IAM employees affected by the flight
      kitchen sale, including reemployment incentives
 
    . Increase in pension benefits
 
    . Inefficiencies due to the impact of job security provisions on
      functions with variable workloads
 
    . Reimbursement for relocations caused by involuntary transfers
 
    . Subject to certain conditions and exceptions, provide IAM
      representation for ramp employees at stations with greater than 40
      daily departures
 
                       SALARIED AND MANAGEMENT INVESTMENT
   
  The Salaried and Management Employee investment remains in force for five
years, nine months and consists of salary reductions and work-rule and policy
changes. In lieu of creating a separate U2 workforce, the Salaried and
Management Employee investment includes the introduction of a "market-based"
new hire program.     
 
  The base investment includes the following features:
 
    . Reduction in wage rates of 8.25%
 
    . No pay raise during first three years other than promotion and
      existing progression increases
 
    . Reduction in force of 127 management positions
 
                                       17
<PAGE>
 
  Additional work-rule changes include:
 
    . Elimination of the half-hour paid lunch period on overtime
 
    . Reduced eligibility for shift differential pay
 
    . Reduction of compensation for extended medical leave
 
    . Reduced reimbursement for certain management relocations
 
    . Four holidays changed to "floating" status to eliminate premium pay
      for such holidays worked
 
    . Reduce salary guarantee for part-time employees
 
  The market-based new-hire program includes the following features:
 
    . Maximum compensation levels reduced to market rates at other
      comparable employers (40-55%  reduction)
 
    . Requirement of 25% employee copayment on medical coverage
 
    . Reductions in vacation, sick leave and dental insurance benefits
 
  Partially offsetting these investments was:
 
    . Potential wage increase in years 4 and 5, based on similar factors to
      those for the ALPA and  IAM-represented employees and taking into
      account wage increases, if any, for such represented  employees
 
  In addition, Salaried and Management Employee benefits under the Company's
defined benefit pension plan, disability plan and life insurance plan will be
based on each employee's pre-transaction hourly rate of pay (without regard to
the 8.25% wage rate reduction) until such time as such employee's actual hourly
rate exceeds that amount or until such employee is demoted, at which time in
either case such employee's actual hourly rate will be used from that point
forward.
 
                              TOTAL LABOR SAVINGS
   
  The changes to salaries, benefits and work-rules discussed above represented
approximately $5.2 billion in estimated savings, with an estimated net present
value of over $3.3 billion:

                              SHORT-HAUL SAVINGS
 
  With the emergence of low-cost, low-frills carriers such as Southwest,
United's cost structure has not been competitive in certain short-haul
markets. To date, United, burdened by higher costs than these carriers, has
maintained a full-service product in these markets to retain passengers
connecting to long-haul domestic and international flights, which are the core
of United's route network. See "--Implementation of the "Airline-Within-An-
Airline' (U2)".
 
  The employee investments are expected to provide United with wage rates and
work-rules that are believed to be competitive with low-cost carriers. This
should permit United to be more competitive on many short-haul routes. Given
these wage rates and work-rules, United should be able to implement a low-
frills, high-frequency "airline-within-an-airline" that can compete for the
extremely price-sensitive local passenger. Lower labor costs and work-rule
changes are the cornerstones for achieving a variety of related cost saving
actions. The combination of labor, work-rule changes and other cost savings
are intended to allow United to be service, price and cost competitive with
low-frills, low-cost carriers.
 
The U2 operation is expected to have the following features:
 
 . Improved Utilization Through a combination of reducing aircraft turnaround
    times, increasing frequency on existing routes and adding service in new
    markets, U2 is intended to operate with a greatly improved asset
    utilization. These enhancements are expected to allow United to leverage
    its fixed asset base--aircraft, airport space, ground equipment and both
    field and staff personnel--across a greater number of departures, and
    thereby to permit improvement in the profitability of marginal operations.
 
 . Limited Product Product and service levels will be reduced to more closely
    match the service levels offered by the competition on short-haul routes:
    beverage and peanuts service only, limited onboard amenities, streamlined
    reservations and airport check-in processes and a reduced Mileage Plus
    frequent flyer program.
 
 . Reduced Distribution Expense The experience of low-cost carriers has
    demonstrated that offering (and promoting) consistent, believably low
    fares and high-frequency service increases direct airline-to-customer
    ticketing. These and similar strategies employed by low-cost carriers are
    intended to be implemented to reduce distribution costs.

                      SUMMARY OF INVESTMENTS AND SAVINGS
   
  In total, the Plan of Recapitalization was estimated to provide United with
approximately $8.2 billion in improved operating earnings over the twelve-year
period, equating to a net present value of approximately $4.9 billion.
Approximately $5.2 billion of the total improvement was expected to arise from
savings in labor costs, with the remaining approximately $3.0 billion expected
to arise from improvements associated with the U2 operation. Of course, future
financial results are inherently subject to significant business, economic
    
                                      19

and competitive uncertainties and contingencies and to future business
decisions taken by corporate management, and no assurance can be given that
the estimated earnings improvement will be achieved.

CERTAIN REVENUE AND EARNINGS SCENARIOS
 
  The Company does not as a matter of course publicly disclose projections or
forecasts as to future revenues or earnings. MANAGEMENT HAS NOT UPDATED AND
REVISED AND DOES NOT INTEND TO UPDATE FURTHER OR OTHERWISE REVISE THE REVENUE
OR EARNINGS SCENARIOS CONTAINED HEREIN TO REFLECT CIRCUMSTANCES EXISTING OR
CHANGES OCCURRING AFTER MARCH 1994.
 
  NONE OF THE COMPANY, BAH OR ANY OTHER PARTY ASSUMES ANY RESPONSIBILITY FOR
THE ACCURACY OF THE REVENUE AND EARNINGS SCENARIOS CONTAINED HEREIN. THESE
REVENUE AND EARNINGS SCENARIOS, WHILE PRESENTED WITH NUMERICAL SPECIFICITY,
ARE BASED UPON A VARIETY OF ASSUMPTIONS RELATING TO THE BUSINESSES OF THE
COMPANY THAT MAY NOT BE REALIZED AND ARE SUBJECT TO SIGNIFICANT UNCERTAINTIES
AND CONTINGENCIES, MANY OF WHICH ARE BEYOND THE COMPANY'S CONTROL. THERE CAN
BE NO ASSURANCE THAT ANY OF THE REVENUE AND EARNINGS SCENARIOS WILL BE
REALIZED, AND ACTUAL RESULTS MAY VARY MATERIALLY FROM THOSE SHOWN.
   
  The revenue and earnings scenarios should be read together with the
information contained in "Business of the Company," "Selected Consolidated
Financial and Operating Data," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Financial Statements,
all of which are contained in the Company's Annual Report on Form 10-K for the
year ended December 31, 1993 as amended and Quarterly Report on Form 10-Q for
the quarter ended March 31, 1994, as amended, both of which are included
elsewhere in this Proxy Statement/Prospectus.     
 
  August 1993 Revenue Scenarios. In connection with its negotiations with the
Coalition, the Company delivered in August 1993 certain revenue scenarios to
the Coalition. All of such scenarios assumed that (i) United maintained status
quo operations, (ii) recovering worldwide economies would result in higher
yields and (iii) in the longer term, unit revenue growth would slow,
reflecting a tapering off of the economic recovery and the addition of
incremental capacity in the domestic system, principally due to continued
expansion of low-cost carriers.
   
  Such scenarios, which assumed average annual unit revenue growth rates for
the 1993-98 period ranging from 2.0% to 4.2%, were based upon certain
assumptions regarding highly uncertain variables, including but not limited to
sustained world economic upturn, absence of significant non-compensatory
competitive fare actions, absence of fuel price shocks, relatively constant
consumer propensity to spend on air travel and relatively stable industry
capacity growth. The various scenarios differed by the assumed intensity of
the early economic recovery and the severity of later economic slowdowns.     
 
  Of the revenue scenarios developed, the Company's management assigned the
highest probability of occurrence to "Scenario C" which assumed medium unit
revenue growth. The other scenarios, which varied
 
                                      20
<PAGE>
 
in assumed economic conditions, growth rates, yields, capacities, and unit
revenue growth were used to test the sensitivity of the various valuations to
revenue changes from the baseline "Scenario C" case. The August 1993 version
of "Scenario C" showed operating profits increasing from $168 million in 1993
to $620 million in 1998. The highest growth scenario showed operating profit
increasing to $1.182 billion in 1998. The August 1993 scenarios did not
provide for any wage increases other than promotion and progression increases,
unless there existed contractual raises, in which case the contract raise was
included.
 
  "Scenario C" relied upon the following assumptions: (i) passenger unit
revenues growth of 5.5% in 1994 and 4.0% in 1995, reflecting a sustained
economic recovery, (ii) domestic airline industry capacity growth of 1%, (iii)
significant yield increases of 3.0% to 4.5%, reflecting a return of fares to
levels prevailing prior to Value Pricing (a pricing strategy introduced by
American Airlines ("American") in 1992 which led to significant discounting in
the airline industry) and prior to the recession, (iv) moderate traffic
increases of 2% and (v) unit revenue growth to slow to 3.0% in 1996, 2.5% in
1997 and 2.0% in 1998, reflecting industry capacity growth rising to 2% per
year, yield growth moderating to 2.0%, and traffic increases of 2%.
   
  March 1994 Revenue Scenario C. Subsequent to the initial development of the
revenue scenarios, the Company updated Scenario C for use in valuations
(including the valuations performed by American Appraisal and Houlihan Lokey
Howard & Zukin ("Houlihan Lokey"), the financial advisor to State Street, the
trustee (the "ESOP Trustee") of the employee stock ownership plans
contemplated by the Plan of Recapitalization (the "ESOPs"); and presentations
to rating agencies (including those given to Standard & Poor's and Moody's).
The status quo case ("Status Quo Scenario C") is based on the assumption that
(i) operations continue as they are with no labor cost reductions and (ii) no
salary increases are granted to any labor group (other than promotion and
progression increases) unless there exists contractual raises in which case
the contractual raise was included.     
   
  THE MOST RECENT STATUS QUO SCENARIO C MODEL WAS PREPARED AS OF MARCH 29,
1994. THIS MODEL, WHICH WAS SUBJECT TO VARIOUS ASSUMPTIONS THAT MAY NOT BE
REALIZED, HAS NOT BEEN UPDATED SINCE MARCH 29, 1994 AND IS SUBJECT TO
SIGNIFICANT UNCERTAINTIES AND CONTINGENCIES. NO STOCKHOLDER OR OTHER PERSON
SHOULD RELY ON SUCH MODEL IN MAKING AN INVESTMENT DECISION WITH RESPECT TO ANY
SECURITIES OF THE COMPANY.

EFFECT OF THE RECAPITALIZATION ON INCOME STATEMENT, BOOK EQUITY AND CASH FLOW
   
  The effect of the Recapitalization on the Company's equity will be to
immediately reduce it by approximately $1.5 billion due primarily to the
distribution of cash and Debenture as part of the Recapitalization
Consideration, vesting of unvested restricted stock and transaction costs.
Based on the Company's analyses, the reduction in book equity was expected to
be earned back by year end 1997. The reasons for the rapid recovery of the
reduction in equity were increases in net income and the effect of employee
stock ownership plan accounting. Additionally, the Company's cash balance was
expected to grow to be $3.7 billion greater than what it would have otherwise
been had the Recapitalization not been consummated.     
 
                                      21
<PAGE>
 
   
  The following analysis shows the variance from the Status Quo Scenario C
model resulting from the anticipated effects of the Recapitalization. This
analysis is based on an assumed purchase price for the Class 1 ESOP Preferred
Stock at the Effective Time of $120 per share. The analysis for subsequent
purchases of such Stock assumes a 14% compounded growth rate for the market
price of New Shares and a purchase price premium for the Class 1 ESOP
Preferred Stock in excess of the market price for the New Shares which is
initially approximately 38%, declining in each successive year. The $120 per
share assumed purchase price of Class 1 ESOP Preferred Stock at the Effective
Time is based on [(i) an assumed market price of an Old Share at the Effective
Time of $131 per share, (ii) an assumed value of the non-New Share portion of
the Recapitalization Consideration of $88 per Old Share, and (iii) a purchase
price premium for the Class 1 ESOP Preferred Stock over the assumed value of a
New Share of 38%.] The actual purchase price for the Class 1 ESOP Preferred
Stock at the Effective Time will be determined using a formula based on (i)
the greater of the pre-Effective Time when issued market price of the New
Shares and the pre-Effective Time market price of the Old Shares, (ii) [an
expected value] for the non-New Share portion of the Recapitalization
Consideration and (iii) a 38% purchase price premium and following the
Effective Time will be based on negotiations with the ESOP Trustee. See "THE
PLAN OF RECAPITALIZATION--Establishment of ESOPs--Sale of ESOP Preferred
Stock--Leveraged ESOP." There can be no assurance as to the purchase price of
the Class 1 ESOP Preferred Stock either at or subsequent to the Effective
Time, the pre-Effective Time when issued market price of the New Shares, the
pre-Effective Time market price of the Old Shares, the value of the non-New
Share portion of the Recapitalization Consideration, or the actual growth
rate, if any, for the market price of the New Shares during the six year wage
investment period. This analysis does not purport to be indicative of the
results of operations that may be obtained in the future. A change in the
purchase price of the Class 1 ESOP Preferred or the New Share market price
growth rate will effect the analysis set forth below. For example, a change in
the assumed purchase price of the Class 1 ESOP Preferred Stock to $130 would
increase the cumulative change in the cash balance in the year 2000 by $80
million. Changing the New Share market price growth rate assumption from 14%
to 10% has the effect of reducing cumulative cash by approximately $70
million.

  As shown above, the Recapitalization is expected to result in an improvement
to cash flow averaging over $550 million per year through the year 2000. This
improvement, aggregating $3.7 billion (excluding the cash consideration
distributed to stockholders as part of the Recapitalization Consideration), is
expected to result from (i) the employee investment which reduces cash expenses
an average of $700 million per year, (ii) favorable tax treatment on ESOP
transactions, which provides over $400 million in annual tax deductions during
the ESOP allocation period, and (iii) partially offsetting the factors
described above, the additional interest expense on the Debentures, dividends
on the Depositary Preferred Shares and foregone interest on the cash
consideration distributed to stockholders in the Recapitalization. The Company
expects that at the Effective Time, taking into account the distribution of
cash in the Recapitalization, it will have an opening cash balance of
approximately $1.6 billion (assuming the Effective Time occurs on June 30,
1994). Cash generated after the Effective Time is assumed to accumulate in a
cash account; if the available cash was used to repay debt, free cash flow
would improve further.     
       
   
  Due to the accounting rules for stock-based compensation such as the ESOPs,
it is expected to be difficult to compare the financial performance of the
Company to companies without significant stock-based compensation. In addition
to this, since there is a circular relationship between the Company's financial
results and its stock price (See "--Certain Risk Factors--Financial Reporting;
Market Assessment" and "--Opinions of the Financial Advisors to the Board"), it
is expected that certain financial analysts may adjust the way they analyze the
Company's performance. While there can be no assurances the Company's financial
performance will be considered other than as reported under generally accepted
accounting principles, the Company believes that the following analysis is
consistent with the manner in which certain analysts will evaluate the
Company's performance.

IMPLEMENTATION OF THE "AIRLINE-WITHIN-AN-AIRLINE " (U2)
 
 Background
 
  In recent years, low-cost carriers, especially Southwest, have grown rapidly.
These carriers offer the consumer air travel service with frequent departures,
minimal inflight service, and simplified fares that are substantially below
standard industry pricing. The consumer acceptance of such carriers has been
especially strong in short-haul markets (markets under 750 miles) in which
consumers readily opt for reliable, low-priced air transportation over the full
service product (typically at higher prices) traditionally offered by carriers.
 
                                       23

  Due to its current cost structure, United has experienced difficulty
competing with low-cost carriers in short-haul markets. When a low-cost carrier
enters a short-haul market, it typically does so with fares substantially below
those existing prior to its entry and with the expectation of stimulating
demand and gaining market share. When a low-cost carrier enters a short-haul
market where United operates, United is faced with three choices:
 
  Do Nothing    Continue service and do not match the lower fares. Traffic
                that is connecting to other United flights would be retained.
                However, without competitive fares in the non-stop short-haul
                market, lost market share as well as a decline in revenues
                would occur. As a result, the economics of the segment would
                deteriorate and it almost certainly would become very
                unprofitable.
 
  Abandon       Discontinue service in the market. This would alleviate losses
                on the non-stop, short-haul segment, assuming the aircraft can
                be profitably redeployed or sold. However, it would also
                deprive United of traffic that connects from the short-haul
                segment to the carrier's long-haul operations. The loss of
                these passengers would hurt the profitability of "beyond"
                segments that rely on the connecting traffic. Typically, this
                decrease in profitability on all "beyond" segments more than
                offsets the benefit from abandoning a short-haul market.
 
  Match Fares   Continue service and match the new low fares. Revenue and
                profitability would decline, but the retention of both local
                and connecting traffic would generally result in less
                deterioration to earnings than either the "Do Nothing" or
                "Abandon" choices.
 
  Accordingly, United often elects to remain in markets following the entrance
of low-cost competition and match the lower fares even though doing so results
in operating losses.
 
  While United believes that matching lower fares is the optimal strategy in
the short-run, it recognizes that it cannot suffer losses in these markets
indefinitely. The ideal strategy, which would allow United to compete
profitably in markets with low-cost competition, is an alternative which is not
currently available to United, that is, to compete with low-cost carriers on a
cost basis. This strategy requires a cost structure similar to that of the low-
cost carriers. United would need to reduce both labor and non-labor costs and
increase productivity in order to establish a competitive cost structure that
would allow United to profitably retain and increase market share. In order to
achieve a competitive cost structure productivity increases are important
elements of the Recapitalization.
 
  The Plan of Recapitalization permits the implementation of the low-cost
strategy described above by providing for the establishment of U2, an airline-
within-an-airline. U2 provisions of the labor agreements permit reduced labor
rates and work-rule changes which are expected to lower costs and improve
productivity. To maximize the benefits associated with those provisions, the
Company will establish separate pilot positions for the U2 operation as well as
a set of U2 routes that are intended to fully leverage potential productivity
and cost savings. The product, pricing, and distribution attributes of U2
markets will be altered from United's to resemble those of a low-cost airline.
U2 markets are expected to be flown as a branded product feature of United
bearing its own distinct name. THERE CAN BE NO ASSURANCE THAT THE U2 OPERATION
WILL BE SUCCESSFULLY IMPLEMENTED OR, IF IMPLEMENTED, THAT THE RESPONSES OF
VARIOUS COMPETITORS WILL NOT REDUCE OR ELIMINATE THE BENEFITS SOUGHT TO BE
OBTAINED.
 
 Operations and Route Systems
 
  Key operational elements of U2 are expected to be as follows:
 
    Short-haul missions  U2 will operate within the contiguous United States
                         in non-stop city pairs of up to 750 nautical miles in
                         "stage length," other than flying between United's
                         hubs and/or international gateway cities (except for
                         Los Angeles basin to San Francisco bay area service
                         which may be flown by U2). At
 
                                       24
<PAGE>
 
                         least 10% of U2 flying must be in city pairs that
                         United has not served for 24 months prior to the
                         introduction of U2 service into that city pair.
 
High frequency           One of the key characteristics of an efficient short-
                         haul operation is high frequency scheduling within a
                         market. United intends to schedule U2 to average
                         approximately ten frequencies per day in most
                         markets.
 
Rapid turn-arounds       United intends to reduce aircraft turn-around time in
                         the U2 operation to 20 minutes as compared to
                         United's current 40 to 45 minutes. The rapid turn-
                         around time is expected to be achieved through
                         product simplification (e.g., reduced food service
                         deliveries) and the streamlining of customer and ramp
                         service procedures.
 
Increased utilization    By combining high frequency with faster turn-arounds,
                         utilization of aircraft, facilities and other
                         equipment is expected to increase, thereby lowering
                         unit costs. As compared with United's fleet, the
                         utilization goal of the U2 fleet is anticipated to
                         improve 16% to 11.0 hours per day from 9.5 hours per
                         day. The increased utilization should allow more
                         trips to be flown by the same fleet of aircraft.
 
 Product
 
  U2 is expected to be marketed as a branded product of United with its own
distinct name (such as "Business One" and "Connoisseur Class" are today).
Travel between U2 and United should appear seamless to the consumer. U2 flights
are expected to feed United long-haul domestic and international flights and
connect with United Express flights.
 
  U2 is expected to offer a simplified, lower-frills product as compared to
mainline United service and will be cost competitive with other low-cost
carriers. Key product features that will differentiate U2 from the mainline
product are:
 
  . Reduced food service
 
  . Reduced onboard amenities
 
  . Expedited customer airport check-in
 
  While the U2 product clearly should be different from mainline United, it is
also expected to be distinguishable from other low-cost carriers.
     
  . Unlike some short-haul carriers, U2 may offer added value to the consumer
    by providing seat assignments     
 
  . To help retain high yield connecting traffic to mainline United, U2
    currently plans to offer first class seating
 
  . Capitalizing on United's marketing strength and global route network, U2
    consumers will be able to participate in one of the industry's highest
    rated frequent flyer programs--United's Mileage Plus program. While the
    program may be adjusted somewhat for U2 travel, the program's benefits
    are expected to help to generate a U2 revenue premium over the
    competition.
 
 Fare Structure
 
  In most markets in which U2 is expected to compete, fares have already been
reduced by other low-cost carriers, and United's fares have been reduced to
competitive levels. U2 intends to maintain United's current pricing practice of
matching competitors' low fares, although U2 intends to heavily promote low
fare levels. The objective in maintaining and promoting the low fares is to
build customer trust so that when they purchase a ticket on a U2 flight, they
know they are obtaining competitive value in the market and do not need to shop
the fare.
 
                                       25
<PAGE>
 
 Distribution
 
  The experience of low-cost carriers has demonstrated that offering and
promoting consistent, believably low fares and high-frequency service increases
direct airline-to-customer ticketing. These and similar strategies employed by
low-cost carriers are expected to be implemented to reduce distribution costs.
 
 Roll-out
 
  The Company expects that U2 will be rolled out no later than four to six
months after the Effective Time and will be implemented in the short-haul
markets as quickly as possible. It is currently expected that by year 5, U2
will operate approximately 130 aircraft and represent approximately 20% of
system "block hours". Block hours is a measure of the time an aircraft is in
motion (i.e. from the time it pushes back from the gate at the departing
airport until it pulls up to the gate upon arrival). Factors affecting the rate
of roll-out include market conditions, pilot attrition, growth of the airline
and changes in the fleet plan.
 
  B737 aircraft are expected to be utilized in the U2 operations. To maximize
fleet efficiency and to have the flexibility of swapping aircraft between the
U2 and United fleet, no changes are expected to be made to livery or interior
configuration.
 
UNIT COSTS
 
  Unit cost, a common industry measure of cost effectiveness, measures the cost
of flying one airplane seat one mile. Due principally to the base employee
investments, increased productivity, the U2 labor provisions and the other
savings associated with the U2 operation, U2's unit costs (calculated on an
incremental basis for short-haul markets) are expected to drop by 30% from
United's existing costs on short-haul routes:

RECOMMENDATION OF THE BOARD
   
  The Board has approved the Initial Plan of Recapitalization and the Plan of
Recapitalization and has determined that the Recapitalization is fair to the
holders of Old Shares. The Board recommends that stockholders vote FOR the Plan
of Recapitalization and the related matters identified in clauses (ii) through
(vii) in the first paragraph under "INTRODUCTION--Purpose of the Meeting."     
   
  The Board noted that the Recapitalization permits the holders of Old Shares
to receive in exchange for each Old Share either (i) cash in an amount equal to
the sum of (a) $25.80, (b) the proceeds (without deducting the underwriting
discount or other costs) from the sale by United of $15.55 principal amount of
Series A Debentures and $15.55 principal amount of Series B Debentures pursuant
to the United Debt Offering and (c) the proceeds (without deducting the
underwriting discount or other costs) from the sale by the Company of 1.244
Depositary Preferred Shares representing interests in $31.10 aggregate
liquidation preference of Public Preferred Stock pursuant to the UAL Preferred
Offering or (ii) (a) $25.80 in cash, (b) $31.10 in Debentures and (c)
Depositary Preferred Shares representing interests in $31.10 liquidation
preference of Public Preferred Stock, while in either case retaining the same
significant ongoing equity interest in the Company. Under various
circumstances, the value of the consideration to be received by stockholders
could be less than the stated face amount or liquidation preference of the
Debentures or Depositary Preferred Shares. In approving the Initial Plan of
Recapitalization and the Plan of Recapitalization, the Board also considered
that the majority equity position of the employee stock ownership plans is
designed to provide additional incentives for the Company's employees to
promote the success of the Company, which should, in part, inure to the benefit
of the holders of Old Shares. The Board noted that no third party had expressed
an interest in acquiring the Company as an entirety and considered the fact
that the Initial Plan of Recapitalization and the Plan of Recapitalization
would not prevent the Company from pursuing such an alternative if it arose. At
the March 24, 1994 Board Meeting, the Board (with Dr. Brimmer dissenting) voted
in favor of the Initial Plan of Recapitalization. Dr. Brimmer has indicated
that he dissented from such vote because under current economic conditions, he
did not think there were compelling reasons to effect such a     
 
                                       27

transaction at this time. With respect to the Definitive Documentation
Amendment, the Board voted in favor of the Definitive Documentation Amendment,
with Dr. Brimmer abstaining. It was mentioned at the meeting that Mr. Olson,
who was not in attendance, had requested that his opposition to the Definitive
Documentation Amendment be noted.     
       
   
  In reaching its decisions to approve the Initial Plan of Recapitalization and
the Plan of Recapitalization, its determination that the Recapitalization is
fair to the holders of Old Shares and its decision to recommend that the
holders of Old Shares vote for approval and adoption of the Plan of
Recapitalization, the Board consulted with its legal and financial advisors as
well as the Company's management, and considered numerous factors, including,
but not limited to: (i) the business, operations, earnings, properties and
prospects of the Company and United and the perceived need for the Company to
obtain wage concessions and work-rule changes in order to permit United to
compete effectively in the aviation marketplace, (ii) the alternatives
potentially available to the Company to achieve wage concessions and work-rule
changes, as well as a comparison of the risks that would be associated with the
Recapitalization and with such other alternatives, (iii) the terms of the
employee investment contemplated by the Initial Plan of Recapitalization and
the Plan of Recapitalization, including the reduction in cash expense, the
favorable tax treatment of the ESOP transactions, the long-term labor contracts
which limit salary increases and the ability to establish U2, (iv) the fact
that the Recapitalization will provide the holders of Old Shares with an
opportunity to receive cash and, if the Offerings are not consummated,
Debentures and Depositary Preferred Shares representing interests in Public
Preferred Stock for a portion of the value of their Old Shares while retaining
a significant ongoing equity interest in the Company through ownership of New
Shares, (v) the terms of the proposed corporate governance structure, which
contains both certain provisions required by the Coalition and certain
provisions designed for the protection of the holders of New Shares, (vi) the
identity of the new chief executive officer and the new Board (especially the
Independent Directors), and the Board's assessment of such individuals, (vii)
recent market prices for the Old Shares as well as market prices for the past
several years, (viii) the Federal income tax consequences of the
Recapitalization under existing law, (ix) (with respect to the Plan of
Recapitalization) the terms of the Definitive Documentation Amendment providing
for an increase in the percentage of common equity and voting power initially
to be acquired by the employee trusts and a decrease in the range of average
stock prices determined one year after the Effective Time which would result in
an increase in the percent of common equity and voting power to be held by the
employee trusts, (x) (with respect to the Plan of Recapitalization) the terms
of the Definitive Documentation Amendment providing for the Offerings and the
potential to distribute cash, instead of securities, to holders of Old Shares
if the Offerings are consummated, (xi) (with respect to the Plan of
Recapitalization) the use of a market price-based formula for the purchase of
the ESOP Preferred Stock to be purchased at the Effective Time; and (xii) the
opinions of CS First Boston, a nationally recognized investment banking firm,
and the opinions of Lazard, another nationally recognized investment banking
firm, that, based upon the matters described therein, as of the date of each
such opinion, the consideration to be received by the holders of Old Shares
pursuant to the Recapitalization for each Old Share, taken as a whole, was fair
to such stockholders from a financial point of view. See "--Opinions of the
Financial Advisors to the Board," "--Certain Risk Factors" and "--Certain
Revenue and Earnings Scenarios," "THE PLAN OF RECAPITALIZATION" and "MARKET
PRICES OF THE SHARES; DIVIDENDS." In connection with considering such factors,
the Board generally viewed factors (i) through (iv), (vii), (viii) and (x)
through (xii) as supporting the Board's fairness belief and factor (vi) as
neutral (however, the Board was favorably impressed with the identity of the
Independent Directors). With respect to factor (v), while the Board generally
viewed such factor as supporting the Board's fairness belief, the Board did
consider that certain aspects of the governance provisions, such as the ability
of the participants in the ESOP to continue to hold more than 50% of the voting
power of the Company until the economic equity interest held by the ESOPs and
other employee benefit plans sponsored by the Company becomes less than 20% of
the value of the common equity of the Company (see "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Nondilution"), would not
support the Board's fairness belief. With respect to factor (ix), while the
Board viewed this factor as not supporting its fairness belief, it recognized
that in order to obtain the benefits of the Definitive Documentation Amendment,
it was necessary to make such changes. The Board also considered (a) the fact
that the repayment of the Debentures     
 
                                       28
<PAGE>
 
   
and the payment of dividends on the Public Preferred Stock will be dependent on
the Company's operations, assets, credit, cash flow and earning power, (b)
that, as a result of the Recapitalization, there will be a significant increase
in the Company's long-term indebtedness, as well as a substantial negative
balance in stockholders' equity and a significant reduction in cash reserves
and (c) the opinion of American Appraisal with respect to certain solvency and
surplus matters. See "--Certain Risk Factors," "THE PLAN OF RECAPITALIZATION"
and "UNAUDITED PRO FORMA FINANCIAL INFORMATION." In connection with considering
such factors, the Board generally viewed factors (a) and (b) as not supporting
the Board's fairness belief and factor (c) as neutral.     
       
  In view of the circumstances and the wide variety of factors considered in
connection with this evaluation of the Recapitalization, the Board did not find
it practicable to assign relative weights to the factors considered in reaching
its decision.
 
OPINIONS OF THE FINANCIAL ADVISORS TO THE BOARD
       
 Opinion of CS First Boston
   
  On December 22, 1993, March 14, 1994, March 24, 1994 and May 20, 1994, CS
First Boston delivered to the Board its oral opinion that, as of such dates,
the consideration to be received by holders of Old Shares of the Company in
connection with the Recapitalization, taken as a whole, was fair to such
holders of Old Shares from a financial point of view. On December 22, 1993,
March 24, 1994 and May 20, 1994, CS First Boston delivered to the Board its
written opinions that, as of such dates, the consideration to be received by
holders of Old Shares in connection with the Recapitalization, taken as a
whole, was fair to such holders of Old Shares from a financial point of view.
    
   
  THE FULL TEXT OF THE WRITTEN OPINION OF CS FIRST BOSTON DATED MAY 20, 1994
WHICH SETS FORTH THE ASSUMPTIONS MADE, THE MATTERS CONSIDERED AND THE REVIEW
UNDERTAKEN WITH REGARD TO SUCH OPINION, IS ATTACHED AS ANNEX I TO THIS PROXY
STATEMENT/PROSPECTUS. STOCKHOLDERS ARE URGED TO READ SUCH OPINION IN ITS
ENTIRETY. CS FIRST BOSTON'S OPINION IS DIRECTED ONLY TO THE FAIRNESS OF THE
CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF OLD SHARES AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF OLD SHARES AS TO HOW SUCH HOLDER
SHOULD VOTE. THE SUMMARY OF THE OPINION OF CS FIRST BOSTON SET FORTH IN THIS
PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
FULL TEXT OF SUCH OPINION. THE TEXTS OF THE WRITTEN OPINIONS OF CS FIRST BOSTON
DATED DECEMBER 22, 1993 AND MARCH 24, 1994 ARE SUBSTANTIALLY THE SAME AS THE
TEXT OF THE MAY 20, 1994 OPINION (EXCEPT WITH RESPECT TO CHANGES TO THE PLAN OF
RECAPITALIZATION EFFECTED PURSUANT TO THE DEFINITIVE DOCUMENTATION AMENDMENT).
    
  In arriving at its opinions, CS First Boston (i) reviewed the Plan of
Recapitalization and its related schedules, (ii) reviewed certain publicly
available business and financial information relating to the Company, (iii)
reviewed certain other information, including financial forecasts, provided to
CS First Boston by the Company and (iv) met with the Company's management to
discuss the business of the Company. CS First Boston also considered certain
financial and stock market data for the Company and compared that data with
similar data for other publicly held companies in businesses similar to those
of the Company, and it considered the financial terms of certain other business
combinations that have recently been effected. CS First Boston also considered
such other information, financial studies, analyses and investigations and
financial, economic and market criteria that it deemed relevant. CS First
Boston also reviewed the alternative of not effecting the Recapitalization and
of implementing the Fundamental Restructuring Plan described under "BACKGROUND
OF THE PLAN OF RECAPITALIZATION," which, if fully implemented, might result in
a greater value to stockholders than the Recapitalization; however, the opinion
assumed that the Board determined, in light of various factors relating to the
implementation of the Fundamental Restructuring Plan and the availability of
the Recapitalization, not to pursue such implementation. CS First Boston did
assume, however, for purposes of the analyses described below, that, if the
Recapitalization were not effected, the Company would implement the "enhanced
status quo" alternative described under "BACKGROUND OF THE PLAN OF
RECAPITALIZATION," consisting of a variety of significant actions to reduce
costs and, therefore, to enhance profitability and stockholder value.

  In connection with its review, CS First Boston did not independently verify
any of the foregoing information and CS First Boston relied on such information
being complete and accurate in all material respects. With respect to the
financial forecasts, CS First Boston assumed that they had been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the Company's management as to the future financial performance of
the Company. In addition, CS First Boston did not make an independent
evaluation or appraisal of any of the assets of the Company, nor was it
furnished with any such appraisals. CS First Boston was not requested to, and
did not, solicit third party offers to acquire all or any part of the Company,
nor, to CS First Boston's knowledge, has any interest in making such an offer
been presented by any third party, including in response to the public
disclosure regarding discussions between the Company and the Coalition. CS
First Boston assumed that the results expected by the Company's management to
be obtained from the Recapitalization, including those arising from the
employee investment contemplated by the Plan of Recapitalization, will be
realized. CS First Boston's opinion was necessarily based solely upon
information available to it and business, market, economic and other conditions
as they existed on, and could be evaluated as of, the date of such opinion. CS
First Boston's opinion did not address the Company's underlying business
decision to effect the Recapitalization.     
   
  The following is a summary of the analyses that CS First Boston utilized in
arriving at its opinion as to the fairness of the consideration to be received
by the holders of Old Shares of the Company in connection with the
Recapitalization, taken as a whole, from a financial point of view and that CS
First Boston discussed with the Board at the December 22, 1993, March 14, 1994,
March 24, 1994 and May 20, 1994 Board meetings.     
 
  Valuation of the Company
   
  For purposes of its opinion as to the fairness of the consideration to be
received by holders of Old Shares in connection with the Recapitalization,
taken as a whole, from a financial point of view, CS First Boston arrived at a
reference range of values for the Company using three principal valuation
methodologies: a discounted cash flow analysis, a publicly traded comparable
company analysis and a comparable acquisitions analysis. At the December 22,
1993 Board meeting, CS First Boston advised the Board that its overall
reference range per share was $160 to $200. CS First Boston did not update its
overall reference range at the March 14, 1994 or March 24, 1994 Board meetings
but it advised the Board at those meetings that if it had updated its reference
range, the updated range would have been somewhat lower than the range given in
December. At the May 20, 1994, Board meeting, CS First Boston advised the Board
that its overall reference range per share was $135 to $175. CS First Boston
advised the Board that the changes in the reference range resulted from changes
in a number of factors, including, but not limited to, higher interest rates,
lower airline stock prices and updated financial forecast information. The
methodologies used by CS First Boston and the resulting ranges of values, which
were described to the Board at the December 22, 1993 Board meeting but which
were not updated for the Board at the March 14, 1994, March 24, 1994 or May 20,
1994 Board meetings, are described below. If CS First Boston had updated these
analyses, the resulting ranges of values would have been lower than the ranges
that resulted from CS First Boston's December 22, 1993 analyses.     
   
  Discounted Cash Flow Analysis. Using a discounted cash flow analysis, CS
First Boston estimated the present value of the future cash flows that the
Company could be expected to produce over a five-year period from 1994 through
1998 under various assumptions and in accordance with management's forecasts.
The analysis assumed that the "enhanced status quo" alternative would be
implemented. CS First Boston determined an equity market value reference range
for the Company by adding (i) the present value (using discount rates
determined on the basis of an industry weighted average cost of capital ranging
from 8.0% to 10.0%) of the five-year unleveraged free cash flows of the Company
and (ii) the present value of the Company's 1998 terminal value. The terminal
values were determined by multiplying 1998 projected earnings before interest,
taxes, depreciation and amortization ("EBITDA") and 1998 projected net income
by a range of multiples determined based on comparable companies and comparable
acquisitions (ranging from 3.5 times to 5.5 times 1998 EBITDA and 11.0 times to
15.0 times 1998 net income). This analysis resulted in a range of values per
Old Share of the Company on December 22, 1993 of from $160 to $200.

  Publicly Traded Comparable Company Analysis. CS First Boston reviewed and
compared the financial, operating and market performance of the following
group of five domestic commercial airline companies with that of the Company:
AMR Corporation, Continental Airlines, Delta Air Lines, Southwest Airlines and
USAir Group (the "Comparable Group"). CS First Boston examined certain
publicly available or estimated financial data of the Comparable Group,
including total revenue, operating cash flow, operating income, net income to
common shares, earnings per share, depreciation and amortization, interest
expense and capitalized interest, rental expense and net cash flow per share.
CS First Boston also examined and compared various operating ratios and
certain capitalization data. CS First Boston also reviewed market data,
including various trading multiples such as stock price to earnings per share,
equity market capitalization to net cash flow (net income plus depreciation
and amortization) and enterprise value to EBITDA (before and after adjusting
for off-balance sheet operating rental payments). CS First Boston also
considered other financial data (including margins and growth rates) as well
as certain operating information, such as yields and load factors, for the
Comparable Group. This analysis resulted in a range of values per Old Share of
the Company on December 22, 1993 of from $130 to $135.     
   
  Comparable Acquisition Analysis. CS First Boston also reviewed selected
acquisitions in the airline industry, including Continental Air/Air Canada,
Trans World Airlines/Carl Icahn and NWA Inc./Wings Holdings, including the
multiples of enterprise value to revenues (ranging from .85 times to 1.10
times) and equity market value to net cash flow (ranging from 1.5 times to 7.6
times) represented by the consideration in those transactions. This analysis
resulted in a range of values per Old Share of the Company on December 22,
1993 of from $120 to $200.     
 
  Recapitalization Consideration
   
  For purposes of its opinion as to the fairness of the consideration to be
received by holders of Old Shares in connection with the Recapitalization,
taken as a whole, from a financial point of view, CS First Boston arrived at a
reference range of values for the consideration to be received by the holders
of Old Shares in the Recapitalization, consisting of cash, New Shares and, if
the Offerings are not consummated, Debentures and Depositary Preferred Shares
representing the Public Preferred Stock. The interest rates on the Debentures
and the dividend rate on the Public Preferred Stock were initially set upon
the execution of the Plan of Recapitalization. The interest or dividend rate
on each such security will be reset, as of a date to be determined that is not
fewer than five calendar days and not greater than ten calendar days prior to
the Meeting to the rate required to cause each such security to trade at 100%
of its aggregate principal amount (in the case of the Debentures) or at 100%
of its aggregate liquidation preference (in the case of the Public Preferred
Stock) (collectively, "par"), on a fully distributed basis, as of such date
(subject to a maximum potential increase, in each case, of 112.5 basis points
(1.125 percentage points)). Accordingly, CS First Boston's opinion was based
on the assumption that (if the Offerings are not consummated) the final rates
to be borne by such securities would be set so that the Debentures and the
Public Preferred Stock would trade, as of such date, on a fully distributed
basis, at par. CS First Boston advised the Board at the March 24, 1994 meeting
that the reduction of the maximum potential increase in the interest rates on
the Debentures and the dividend rate on the Public Preferred Stock from 150
basis points (1.5 percentage points) (which was the size of the rate cap
arrangement provided for in the Agreement in Principle) to 112.5 basis points
(1.125 percentage points) (the size of the rate cap arrangement provided for
in the Plan of Recapitalization) could reduce the value of the Debentures and
the Public Preferred Stock to be received by the holders of Old Shares in the
Recapitalization by an amount that CS First Boston advised the Board was not
material to the consideration to be received by the holders of Old Shares in
the Recapitalization, taken as a whole. CS First Boston's opinion does not
represent CS First Boston's view, if the Offerings are not consummated as to
what the trading value of the securities actually will be when the securities
are issued to the holders of the Old Shares following consummation of the
Recapitalization. The actual trading values of such securities could be higher
or lower depending upon changes in interest rates, dividend rates, market
conditions, general economic conditions and other factors that generally
influence the price of securities. Because of the large aggregate amount of
the securities (particularly the Public Preferred Stock) that would be issued
to holders of Old     
 
                                      31
<PAGE>
 
   
Shares if the Offerings are not consummated and other factors, such securities
may trade initially, and for an extended period thereafter, at prices below
those at which they would trade on a fully distributed basis. Furthermore, any
valuation of securities is only an approximation, subject to uncertainties and
contingencies. If the Offerings are consummated, the interest rates on the
Debentures and the dividend rate on the Public Preferred Stock may be set at
rates that are in excess of the limitation contained in the Recapitalization
Agreement, in which event the principal amount of the series of Debentures
affected or the number of Depositary Preferred Shares, as the case may be, will
be reduced so that the aggregate amount of interest payable by United or
dividends payable by UAL, as the case may be, with respect to such security
will not exceed amounts specified in the Recapitalization Agreement, and the
amount of the proceeds from the sale of such securities to be received by
holders of Old Shares will be reduced accordingly. In addition, in certain
other circumstances such proceeds could be less than the stated face amount or
liquidation preference of such securities. CS First Boston's opinion was based
on the assumption that, if the Offerings are consummated, the proceeds of the
Debentures and the Depositary Preferred Shares to be received by the holders of
Old Shares will not be less than the principal amounts of Debentures and the
number of Depositary Preferred Shares that would have been distributed to the
holders of Old Shares had the Offerings not been consummated.     
 
  Valuation of the New Shares
 
  The principal valuation methodology used by CS First Boston with respect to
the New Shares to be received by holders of Old Shares in the Recapitalization
was the earnings and cash flow multiple method. A supplemental method referred
to as the "gives/gets" method was also analyzed. These methodologies are
described below:
   
  Earnings and Cash Flow Multiple Method. CS First Boston arrived at a range of
values for the New Shares by reviewing the public market multiples of the
Comparable Group and applying a range of multiples to the Company's estimated
1994 and 1995 earnings per share and net cash flow per share pro forma for the
consummation of the Recapitalization. Because of the way the accounting rules
applicable to "stock based compensation" (which require that stock compensation
expense for periodic stock allocations be measured by the then-current market
value of the shares at the time of allocation) will apply to the share
allocations within the ESOPs, there are complexities as to forecasting future
earnings per share of the Company. The size of the employee stock ownership
plan accounting charge will be affected by the stock price, and the employee
stock ownership plan accounting charge will reduce reported earnings per share
which, in turn, may affect the stock price. In light of this, for purposes of
its analyses, CS First Boston applied a range of multiples to forecasted
results based on two cases: one assuming ratable allocation of the shares
within the ESOPs over the period of the concessions and the other assuming
immediate, full allocation (the latter methodology eliminates the need to
estimate future stock price performance in order to project the Company's
earnings per share). CS First Boston applied a discount to the resulting values
to reflect the potential dilution from the equity collar arrangement (which
will operate to increase the employee trusts' equity ownership from 55% to a
maximum of 63% if the Company's average stock closing price for one year
exceeds certain levels specified in the Plan of Recapitalization). This
analysis resulted in a public market equity value reference range for the
portion of a New Share to be received as part of the Recapitalization
Consideration for one Old Share on December 22, 1993 of $80 to $82, on March
14, 1994 of $73 to $77 and on May 20, 1994 of $55 to $59. CS First Boston
advised the Board that the change in the reference range resulted from changes
in a number of factors, including, but not limited to, higher interest rates,
lower airline stock prices, updated financial forecast information and the
amendments to the Plan of Reorganization.     
 
  "Gives/Gets" Method
 
  "Gives/Gets" is a summary valuation methodology whereby the impact of the
employee investment and the distribution of the Debentures and Public Preferred
Stock on the Company's unaffected stock price (i.e., unaffected by the
possibility of an extraordinary transaction) is considered. The "gives/gets"
analysis started with the trading value of Old Shares, reduced by the increase
in the stock price attributable, in CS First
 
                                       32

Boston's view, to market speculation about a possible employee investment
transaction (minus the present value of the enhancements contained in the
"enhanced status quo" alternative that the Company would have implemented if it
had pursued such alternative but would not implement if the Recapitalization
were effected) and added to this pre-transaction value the present value of the
employee investment and the incremental value realized on the sale of the
flight kitchens to arrive at an implied total equity value. CS First Boston
subtracted from this amount the cash and securities (other than the New Shares)
to be delivered to the holders of Old Shares to arrive at an implied post-
transaction market value. Using this methodology, CS First Boston arrived at a
valuation for the portion of a New Share to be received as part of the
Recapitalization Consideration for one Old Share on December 22, 1993 of $85,
which was presented to the Board primarily for the purpose of describing the
possible adjustment in the percent equity to be held by the ESOPs based on the
trading price of the New Shares during the first year following the Effective
Time (see "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--Additional
Shares"). CS First Boston did not update this analysis at the March 14, 1994,
March 24, 1994 or May 20, 1994 Board meetings.     
   
  In arriving at its written opinions dated December 22, 1993, March 24, 1994
or May 20, 1994 and in discussing its opinions with the Board, CS First Boston
performed certain financial analyses, portions of which are summarized above.
The summary set forth above does not purport to be a complete description of CS
First Boston's analyses. CS First Boston believes that its analyses must be
considered as a whole and that selecting portions of its analyses could create
an incomplete view of the process underlying the opinions. In addition, CS
First Boston may have given various analyses more or less weight than other
analyses, and may have deemed various assumptions more or less probable than
other assumptions, so that the ranges of valuations resulting from any
particular analysis described above should not be taken to be CS First Boston's
view of the actual value of the Company. No company or transaction used in the
publicly traded comparable company analysis or the comparable acquisition
analysis summarized above is identical to the Company or the Recapitalization.
Accordingly, any such analysis of the value of the Company involves complex
considerations and judgments concerning differences in the potential financial
and operating characteristics of the comparable companies as well as other
factors relating to the trading and the acquisition values of the comparable
companies. These and other limitations, including potential legal restrictions
on airline ownership, may detract from the usefulness of either publicly traded
comparable company multiples or purchase price multiples from prior airline
acquisitions as valuation methodologies. In performing its analyses, CS First
Boston made numerous assumptions with respect to industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of the Company and all of which are beyond the
control of CS First Boston. The results of the analyses performed by CS First
Boston are not necessarily indicative of actual values, which may be
significantly more or less favorable than suggested by such analyses.     
   
  The analyses described above were prepared solely as part of CS First
Boston's analysis of the fairness of the Recapitalization Consideration to the
holders of Old Shares. The analyses do not purport to be appraisals or to
reflect the prices at which a company might actually be sold or the actual
trading value of the Debentures, the Depositary Preferred Shares or the New
Shares.     
 
  CS First Boston is an internationally recognized investment banking firm and
regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions and for other purposes. The Board
selected CS First Boston to act as its financial advisor on the basis of CS
First Boston's international reputation and CS First Boston's familiarity with
the Company and the airline industry in general and its experience in the
restructuring of other public companies in similar types of transactions. CS
First Boston has previously acted as financial advisor to the Company in
connection with financing and other matters unrelated to the Recapitalization
for which it has received customary compensation. In the course of its
business, CS First Boston actively trades the debt and equity securities of the
Company for its own account and for the accounts of customers. Accordingly, CS
First Boston may at any time hold a long or short position in such securities.
 
  As compensation for rendering the opinion described above and assisting the
Company in evaluating, structuring, planning and negotiating the financial
aspects of the Recapitalization, the Company has paid CS
 
                                       33
<PAGE>
 
First Boston a retainer of $250,000 and since January 1994 CS First Boston has
been receiving an advisory fee of $100,000 per month, as well as reimbursement
of reasonable out-of-pocket expenses (including fees and disbursements). While
the Company agreed to pay CS First Boston a fee of $2 million contingent upon
consummation of the Recapitalization, CS First Boston's contingent fee is
subject to adjustment based upon amounts paid to other financial advisors in
the Recapitalization. Accordingly, the aggregate amount that CS First Boston
will receive if the Recapitalization is consummated, including retainer and
advisory fees and expense reimbursements paid by the Company, is $5 million
(the success fee to be paid to Lazard upon consummation of the
Recapitalization, as described below under "--Opinion of Lazard") plus the
amount by which CS First Boston's expense reimbursements exceed Lazard's
expense reimbursements. The Company has agreed to indemnify CS First Boston and
its affiliates, their respective directors, officers, partners, agents and
employees and each person, if any, controlling CS First Boston or any of its
affiliates against certain liabilities, including certain liabilities under the
Federal securities laws, relating to or arising out of its engagement.
 
 Opinion of Lazard
   
  On December 22, 1993, March 14, 1994, March 24, 1994 and May 20, 1994, Lazard
delivered to the Board its oral opinion that, as of such dates, the
consideration to be received by holders of Old Shares in connection with the
Recapitalization, taken as a whole, was fair to such holders of Old Shares from
a financial point of view. On December 22, 1993 March 24, 1993 and May 20,
1994, Lazard delivered to the Board its written opinions that, as of such
dates, the consideration to be received by holders of Old Shares in connection
with the Recapitalization, taken as a whole, was fair to such holders of Old
Shares from a financial point of view.

  In connection with its review, Lazard did not independently verify any of the
foregoing information and Lazard relied on such information being complete and
accurate in all material respects. With respect to the financial forecasts,
Lazard assumed that they had been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the Company's management as

Company, nor was it furnished with any such appraisals. Lazard was not

Lazard assumed that the results expected by the Company's management to be

investment contemplated by the Plan of Recapitalization will be realized.
Lazard's opinion was necessarily based solely upon information available to it
and business, market, economic and other conditions as they existed on, and
could be evaluated as of, the date of such opinion. Lazard's opinion did not
address the Company's underlying business decision to effect the
Recapitalization.     
   
  The following is a summary of the analyses that Lazard utilized in arriving
at its opinion as to the fairness of the consideration to be received by the
holders of Old Shares of the Company in connection with the Recapitalization,
taken as a whole, from a financial point of view and that Lazard discussed with
the Board at the December 22, 1993, March 14, 1994, March 24, 1994 and May 20,
1994 Board meetings.     
 
  VALUATION OF THE COMPANY
   
  For purposes of its opinion as to the fairness of the consideration to be
received by holders of Old Shares in connection with the Recapitalization,
taken as a whole, from a financial point of view, Lazard arrived at a reference
range of values for the Company using three principal valuation methodologies:
a discounted cash flow analysis, a publicly traded comparable company analysis
and an unaffected trading value analysis. At the December 22, 1993 Board
meeting, Lazard advised the Board that its overall reference range per share
was $150 to $190. Lazard did not update its overall reference range at the
March 14, 1994 or March 24, 1994 Board meetings but it advised the Board at
those meetings that if it had updated its reference range, the updated range
would have been somewhat lower than the range given in December. At the May 20,
1994, Board meeting, Lazard advised the Board that its overall reference range
per share was $135 to $160. Lazard advised the Board that the changes in the
reference range resulted from changes in a number of factors, including, but
not limited to, higher interest rates, lower airline stock prices and updated
financial forecast information. The methodologies used by Lazard and the
resulting ranges of values, which were described to the Board at the December
22, 1993 Board meeting but which were not updated for the Board at the March
14, 1994, March 24, 1994 or May 20, 1994 Board meetings, are described below.
If Lazard had updated these analyses, the resulting ranges of values would have
been lower than the ranges that resulted from Lazard's December 22, 1993
analyses.     
   
  Discounted Cash Flow Analysis. Using a discounted cash flow analysis, Lazard
estimated the present value of the future cash flows that the Company could be
expected to produce over a ten-year period from 1994 through 2003 under various
assumptions in accordance with management's forecasts. The analysis assumed
that the "enhanced status quo" alternative would be implemented. Lazard
determined a range of total values for the Company by adding (i) the present
value (using discount rates ranging from 8.0% to 12.0%) of the ten-year
unleveraged free cash flows of the Company and (ii) the present value of the
Company's 2003 terminal value. A range of terminal values was determined by
multiplying 2003 projected net income by a range of multiples determined based
on the trading multiples of selected publicly traded comparable companies (AMR
Corporation, Continental Airlines, Delta Air Lines, Southwest Airlines and
USAir Group (the "Comparable Group")) and other factors (ranging from 11.0
times to 15.0 times 2003 net income). This analysis resulted in a range of
values per Old Share for the Company on December 22, 1993 of from $170 to $210.
    
  Publicly Traded Comparable Company Analysis. Lazard reviewed and compared the
financial, market and operating performance of the companies in the Comparable
Group with that of the Company. Of the companies in the Comparable Group,
Lazard focused its analyses principally on AMR Corporation, Delta
 
                                       35
<PAGE>
 
   
Air Lines and Southwest Airlines. Lazard examined certain publicly available
financial data, including total revenue, EBITDA, earnings before interest and
taxes, earnings per share and net cash flow (net income plus depreciation) per
share and reviewed various trading multiples for the Comparable Group. Lazard
also considered other financial data (including margins and growth rates) as
well as certain operating information (such as yields and load factors) for the
Comparable Group. This analysis resulted in a range of appropriate multiples
for the Company, which, in turn, resulted in a range of values per Old Share of
the Company on December 22, 1993 of from $140 to $180.     
   
  Unaffected Trading Value Analysis. Lazard reviewed the history of the trading
prices of the Company's common stock over various periods and at various times
(including prior to the first public disclosure of the Coalition's proposal for
a restructuring of the Company in July 1993) and compared such prices to the
prices of other airline companies over such periods and at such times in order
to estimate a normalized trading value for the Old Shares that would not
reflect a significant premium attributable to the disclosure of, or market
speculation about, a possible employee investment transaction. This analysis
resulted in an unaffected trading range per Old Share of the Company on
December 22, 1993 of from $130 to $135.     
 
  RECAPITALIZATION CONSIDERATION
   
  For purposes of its opinion as to the fairness of the consideration to be
received by holders of Old Shares of the Company in connection with the
Recapitalization, taken as a whole, from a financial point of view, Lazard
arrived at a reference range of values for the consideration to be received by
the holders of Old Shares in the Recapitalization, consisting of cash, New
Shares and, if the Offerings are not consummated, Debentures and Depositary
Preferred Shares representing the Public Preferred Stock. The interest rates on
the Debentures and the dividend rate on the Public Preferred Stock were
initially set upon the execution of the Plan of Recapitalization. The interest
or dividend rate on each such security will be reset, as of a date to be
determined that is not fewer than five calendar days and not greater than ten
calendar days prior to the Meeting, to the rate required to cause each such
security to trade at 100% of its aggregate principal amount (in the case of the
Debentures) or at 100% of its aggregate liquidation preference (in the case of
the Public Preferred Stock) (collectively, "par"), on a fully distributed
basis, as of such date (subject to a maximum potential increase, in each case,
of 112.5 basis points (1.125 percentage points)). Accordingly, Lazard's opinion
was based on the assumption that (if the Offerings are not consummated) the
final rates to be borne by such securities would be set so that the Debentures
and the Public Preferred Stock would trade, as of such date, on a fully
distributed basis, at par. Lazard advised the Board at the March 24, 1994
meeting that the reduction of the maximum potential increase in the interest
rates on the Debentures and the dividend rate on the Public Preferred Stock
from 150 basis points (1.5 percentage points) (which was the rate cap provided
for in the Agreement in Principle) to 112.5 basis points (1.125 percentage
points) (the rate cap provided for in the Plan of Recapitalization) could
reduce the value of the Debentures and the Public Preferred Stock to be
received by the holders of Old Shares in the Recapitalization by an amount that
Lazard advised the Board was not material to the consideration to be received
by the holders of Old Shares in the Recapitalization, taken as a whole.
Lazard's opinion does not represent Lazard's view, if the Offerings are not
consummated, as to what the trading value of the securities actually will be
when the securities are issued to holders of the Old Shares following
consummation of the Recapitalization. The actual trading values of such
securities could be higher or lower depending upon changes in interest rates,
dividend rates, market conditions, general economic conditions and other
factors that generally influence the price of securities. Because of the large
aggregate amount of the securities (particularly the Public Preferred Stock)
that would be issued to holders of Old Shares if the Offerings are not
consummated and other factors, such securities may trade initially, and for an
extended period thereafter, at prices below those at which they would trade on
a fully distributed basis. Furthermore, any valuation of securities is only an
approximation, subject to uncertainties and contingencies. If the Offerings are
consummated, the interest rates on the Debentures and the dividend rate on the
Public Preferred Stock may be set at rates that are in excess of the limitation
contained in the Recapitalization Agreement, in which event the principal
amount of the series of Debentures affected or the number of Depositary
Preferred Shares, as the case may be, will be reduced so that the aggregate
amount of     
 
                                       36
<PAGE>
 
   
interest payable by United or dividends payable by UAL, as the case may be,
with respect to such security will not exceed amounts specified in the
Recapitalization Agreement, and the amount of the proceeds from the sale of
such securities to be received by holders of Old Shares will be reduced
accordingly. In addition, in certain other circumstances such proceeds could be
less than the stated face amount or liquidation preference of such securities.
Lazard's opinion was based on the assumption that, if the Offerings are
consummated, the proceeds of the Debentures and the Depositary Preferred Shares
to be received by the holders of Old Shares will not be less than the principal
amounts of Debentures and the number of Depositary Preferred Shares that would
have been distributed to the holders of Old Shares had the Offerings not been
consummated.     
 
  Valuation of the New Shares
 
  The principal valuation methodology used by Lazard with respect to the New
Shares to be received by holders of Old Shares in the Recapitalization was the
earnings and cash flow multiple method. The "gives/gets" method was also
analyzed. These methodologies are described below:
   
  Earnings and Cash Flow Multiple Method. Lazard arrived at a range of values
for the New Shares by reviewing the public market multiples of the Comparable
Group and the Company, and applying a range of multiples to the Company's
estimated 1994 and 1995 earnings per share and net cash flow per share pro
forma for the consummation of the Recapitalization. Because of the way the
accounting rules applicable to "stock based compensation" (which require that
stock compensation expense for periodic stock allocations be measured by the
then-current market value of the shares at the time of allocation) will apply
to the share allocations within the ESOPs, there are complexities to
forecasting future earnings per share of the Company. The size of the employee
stock ownership plan accounting charge will be affected by the stock price, and
the employee stock ownership plan accounting charge will reduce reported
earnings per share which, in turn, may affect the stock price. For purposes of
its analyses, Lazard applied a range of multiples to forecasted results based
on two cases: one assuming ratable allocation of the shares within the ESOPs
over the period of the concessions and the other assuming immediate, full
allocation (the latter methodology eliminates the need to estimate future stock
price performance in order to project the Company's earnings per share). Lazard
applied a discount to the resulting values to reflect the potential dilution
from the equity collar arrangement which will increase the employee trusts'
equity ownership from 55% to a maximum of 63% if the Company's average stock
closing price for one year exceeds certain levels specified in the Plan of
Recapitalization). This analysis resulted in a public market equity value
reference range for the portion of a New Share to be received as part of the
Recapitalization Consideration for one Old Share on December 22, 1993 of $80 to
$82, on March 14, 1994 of $73 to $77 and on May 20, 1994 of $55 to $61. Lazard
advised the Board that the changes in the reference range resulted from changes
in a number of factors, including but not limited to, higher interest rates,
lower airline stock prices, updated financial forecast information and the
amendments to the Plan of Reorganization.     
 
  "Gives/Gets" Method
 
  "Gives/Gets" is a summary valuation methodology whereby the impact of the
employee investment and the distribution of the Debentures and Public Preferred
Stock on the Company's unaffected trading value is considered. The "gives/gets"
analysis started with the trading value of Old Shares, reduced by the increase
in the stock price attributable, in Lazard's view, to market speculation about
a possible employee investment transaction (determined as described under "--
Unaffected Trading Value Analysis" above) (minus the present value of the
enhancements contained in the "enhanced status quo" alternative that the
Company would have implemented but would not in the Recapitalization) and added
to this pre-transaction value the present value of the employee investment and
the incremental value realized on the sale of the flight kitchens to arrive at
an implied total equity value. Lazard subtracted from this amount the cash and
securities (other than the New Shares) to be delivered to the holders of the
Old Shares to arrive at an implied post-transaction market value. Using this
methodology, Lazard arrived at a valuation for the portion of a New Share to be
 
                                       37
<PAGE>
 
   
received as part of the Recapitalization Consideration for one Old Share on
December 22, 1993 of approximately $85, which was presented to the Board
primarily for the purpose of describing the possible adjustment in the percent
equity to be held by the ESOPs based on the trading price of the New Shares
during the first year following the Effective Time (See "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Additional Shares"). Lazard did not
update this analysis at the March 14, 1994, March 24, 1994 or May 20, 1994
Board meetings.     
   
  In arriving at its written opinions dated December 22, 1993, March 24, 1994
and May 20, 1994, and in discussing its opinions with the Board, Lazard
performed certain financial analyses, portions of which are summarized above.
The summary set forth above does not purport to be a complete description of
Lazard's analyses. Lazard believes that its analyses must be considered as a
whole and that selecting portions of its analyses could create an incomplete
view of the process underlying the opinions. In addition, Lazard may have
given various analyses more or less weight than other analyses, and may have
deemed various assumptions more or less probable than other assumptions, so
that the ranges of valuations resulting from any particular analysis described
above should not be taken to be Lazard's view of the actual value of the
Company. No company used in the publicly traded comparable company analysis
summarized above is identical to the Company. Accordingly, any such analysis
of the value of the Company involves complex considerations and judgments
concerning differences in the potential financial and operating
characteristics of the comparable companies as well as other factors relating
to the trading values of the Comparable Group. In performing its analyses,
Lazard made numerous assumptions with respect to industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of the Company and all of which are beyond the
control of Lazard. The results of the analyses performed by Lazard are not
necessarily indicative of actual values, which may be significantly more or
less favorable than suggested by such analyses.     
   
  The analyses described above were prepared solely as part of Lazard's
analysis of the fairness of the Recapitalization Consideration to the holders
of Old Shares. The analyses do not purport to be appraisals or to reflect the
prices at which a company might actually be sold or the actual trading value
of the Debentures, the Depositary Preferred Shares or the New Shares.     
 
  Lazard is an internationally recognized investment banking firm and
regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions and for other purposes. Lazard was
chosen by the Company to act as financial advisor in connection with the
negotiations with the Coalition and the Recapitalization because of its
familiarity with the Company and the airline industry in general, because of
its general experience in restructuring other public companies in similar
types of transactions and because it was believed that the experience of Mr.
Felix Rohatyn, a general partner of Lazard, who had been on the National
Commission to Ensure a Strong Competitive Airline Industry, would provide
additional valuable insight on the Company's situation and its discussions
with the Coalition.
 
  In consideration for Lazard's services, the Company paid Lazard a retainer
of $500,000 in January 1994 and agreed to pay Lazard a financial advisory fee
of $100,000 per month (prorated for any portion of a full month) payable on
the last day of each month beginning January 31, 1994. The Company has agreed
to reimburse Lazard for its out-of-pocket expenses, including reasonable fees
and disbursements of counsel. The Company has also agreed to pay Lazard a
success fee of $5 million upon the completion of the Recapitalization against
which the retainer and financial advisory fees and expense reimbursements will
be credited. The Company has agreed to indemnify Lazard and its affiliates,
their respective directors, officers, partners, agents and employees and each
person, if any, controlling Lazard or any of its affiliates against certain
liabilities, including certain liabilities under the Federal securities laws,
relating to or arising out of its engagement.
 
OPINION OF VALUATION FIRM
 
  In order to assist the Board, the Company retained American Appraisal, a
nationally recognized independent valuation firm. American Appraisal delivered
an oral report to the Board at the March 14, 1994
 
                                      38

meeting and a written opinion to the Board and the Company dated as of March
14, 1994 (the "American Appraisal Opinion"). It is a condition to consummation
of the Recapitalization that the Board shall have received an updated opinion
from American Appraisal substantially similar to the American Appraisal Opinion
as of the Effective Time. See "THE PLAN OF RECAPITALIZATION--Terms and
Conditions." The full text of the American Appraisal Opinion, which sets forth
the assumptions made, the matters considered and the review undertaken with
regard to such opinion is filed as an Exhibit to the Registration Statement of
which this Proxy Statement/Prospectus is a part. The summary of the American
Appraisal Opinion set forth in this Proxy Statement/Prospectus is qualified in
its entirety by reference to the full text of such opinion.     
 
  In rendering the American Appraisal Opinion, American Appraisal valued the
assets of the Company (on a consolidated basis) and United (on a consolidated
basis), as going concerns, both immediately before and after, and giving effect
to, the Recapitalization. The valuation included the aggregate assets of the
business enterprise of each of the Company (on a consolidated basis) and United
(on a consolidated basis), or total invested capital as represented by the
total net working capital, tangible plant, property and equipment and
intangible assets of the respective business enterprises. American Appraisal
stated that it believed this to be a reasonable basis on which to value the
Company and United and that nothing has come to its attention that caused it to
believe that each of the Company (on a consolidated basis) and United (on a
consolidated basis), before and after the Recapitalization, will not be going
concerns.
 
  The American Appraisal Opinion is subject to the conditions that (i) any sale
of each of the Company (on a consolidated basis) or United (on a consolidated
basis) will be completed as the sale of an ongoing business entity within a
commercially reasonable period and (ii) a "commercially reasonable period" of
time means at least twelve months for a willing buyer and a willing seller to
agree on price and terms, plus the time necessary to complete the sale of the
Company (on a consolidated basis) and United (on a consolidated basis). In
connection with the opinion of the fair value of each of the Company (on a
consolidated basis) and United (on a consolidated basis), American Appraisal
was provided historical and projected operating results. In addition to this
information, American Appraisal was provided other operating data and
information, all of which has been accepted by American Appraisal, without
independent verification, as representing a fair statement of historical and
projected results of each of the Company (on a consolidated basis) and United
(on a consolidated basis) in the opinion of the management of each of the
Company and United. However, the American Appraisal Opinion states that, in the
course of its investigation, nothing has led it to believe that its acceptance
and reliance on such operating data and information was unreasonable.
 
  American Appraisal's determination of the fair value of each of the Company
(on a consolidated basis) and United (on a consolidated basis) was based on the
generally accepted valuation principles used in the market and discounted cash
flow approaches, described as follows:
 
    Market Approach--Based on current stock market prices of publicly held
  companies whose businesses are similar to that of the Company (on a
  consolidated basis) and United (on a consolidated basis) and premiums paid
  over market price by acquirors of total or controlling ownership in such
  businesses.
 
    Discounted Cash Flow Approach--Based on the present value of each of the
  Company's (on a consolidated basis) and United's (on a consolidated basis)
  future debt-free operating cash flow as estimated by the managements of
  each of the Company (on a consolidated basis) and United (on a consolidated
  basis) and contained in Status Quo Scenario C. The present value is
  determined by discounting the projected operating cash flow at a rate of
  return that reflects the financial and business risks of each of the
  Company (on a consolidated basis) and United (on a consolidated basis).
 
  In determining the amount that would be required to pay the total probable
liabilities on the respective dates that the Company's (on a consolidated
basis) and United's (on a consolidated basis) liabilities and contingent
liabilities become absolute and matured, for purposes of their opinion,
American Appraisal applied valuation techniques, including present value
analysis, using appropriate rates over appropriate periods to
 
                                       39
<PAGE>
 
the amounts that will be required from time to time to pay such liabilities and
contingent liabilities as they become absolute and matured based on their
scheduled maturities.
 
  In the course of its investigation of identified contingent liabilities, the
areas brought to the attention of American Appraisal by the managements of the
Company (on a consolidated basis) and United (on a consolidated basis)
included, (i) environmental matters, (ii) the adequacy of the corporate
insurance program, (iii) tax audit exposure, (iv) the liability for the pension
and welfare benefits program, (v) labor and collective bargaining issues and
(vi) various lawsuits and claims filed and/or pending against the Company (on a
consolidated basis) and United (on a consolidated basis).
 
  Reserves for contingent liabilities have been made in the pro forma
consolidated balance sheet prepared and furnished to American Appraisal by each
of the managements of the Company (on a consolidated basis) and United (on a
consolidated basis), and provisions for the ongoing expenses related to these
issues have been included with the projection of income and expenses presented
in the financial projections, and are considered in American Appraisal's
valuation study as ongoing business operating expenses. American Appraisal has
taken these identified contingent liabilities into account in rendering the
American Appraisal Opinion and has concluded that such liabilities and ongoing
expenses do not require any qualification of the American Appraisal Opinion.
American Appraisal's conclusion is based on: (i) its review of various
acquisition transactions, including leveraged transactions and significant
debt-financed recapitalization transactions, involving corporations engaged in
businesses similar to those of each of the Company (on a consolidated basis)
and United (on a consolidated basis), (ii) the opinion of the managements of
each of the Company (on a consolidated basis) and United (on a consolidated
basis) that the issues concerning various lawsuits, claims and other identified
contingent liabilities do not and are not reasonably likely to have a material
adverse effect on the consolidated financial position of each of the Company
(on a consolidated basis) and United (on a consolidated basis) and (iii) its
discussions with the managements, accountants, consultants and counsel of each
of the Company (on a consolidated basis) and United (on a consolidated basis),
concerning claims and other contingent liabilities and the possible effect of
the foregoing on each of the Company and United as well as its investigation of
the various lawsuits.
   
  American Appraisal assumed that the total liabilities of each of the Company
(on a consolidated basis) and United (on a consolidated basis) will be only
those liabilities set forth in the financial projections and the pro forma
balance sheet as of December 31, 1993 of each of the Company (on a consolidated
basis) and United (on a consolidated basis) and the identified contingent
liabilities referred to in the American Appraisal Opinion. The American
Appraisal Opinion states that, in the course of its investigation, nothing came
to American Appraisal's attention that caused American Appraisal to believe
such assumptions to be unreasonable. The pro forma balance sheet used by
American Appraisal is the unaudited pro forma condensed balance sheet as of
December 31, 1993 for each of the Company (on a consolidated basis) and United
(on a consolidated basis), each adjusted to give effect to the planned
financing of the Recapitalization and restated to reflect the fair value of
each of the Company (on a consolidated basis) and United (on a consolidated
basis).     
 
  The Company's and United's management has represented to American Appraisal,
and American Appraisal has relied on the representations of the managements of
the Company and United, that no adverse changes have occurred since the
preparation of the Company's and United's pro forma balance sheet and financial
analyses that would materially impact its content. The American Appraisal
Opinion states that nothing has come to American Appraisal's attention that
would lead it to believe that its reliance on such representations is
unreasonable.
 
  In connection with the American Appraisal Opinion, American Appraisal made
such reviews, analyses and inquiries as it has deemed necessary and appropriate
under the circumstances. Among other things, American Appraisal (i) reviewed
the documents related to the Recapitalization and reporting documents filed
with the Commission, (ii) reviewed financial analyses and inquired of
managements of the Company and United as to the foundation for any such
analyses and the basic assumptions made in the preparation of Status
 
                                       40
<PAGE>
 
Quo Scenario C relating to the type of business, geographic markets, domestic
and international economic conditions and capital facilities and working
capital requirements, (iii) reviewed audited and unaudited historical income
statements, balance sheets and statements of sources and uses of funds of the
Company and United as provided by management and its accountants, (iv) visited
the Company's and United's headquarters and selected facilities to discuss
historical and estimated operating results and industry data, including the
impact of future trends on the industry and the Company and United, as well as
the effects of the Recapitalization, (v) reviewed internal financial analyses
and other internally generated data of the Company and United including asset
valuations, (vi) inquired of managements of the Company and United and their
respective financial advisors as to estimated levels of cash and working
capital required by the Company and United, (vii) reviewed certain publicly
available economic, financial and market information as it relates to the
business operations of the Company and United, (viii) reviewed information
regarding businesses similar to the Company and United and investigated the
financial terms and post-transaction performance of recent acquisitions, (ix)
consulted with industry, economic and statistical experts, as necessary, (x)
discussed all of the foregoing information, where appropriate, with managements
of the Company and United and their respective agents, accountants and
financial advisors and (xi) conducted such other studies, analyses and
investigations as American Appraisal deemed relevant or necessary for purposes
of the opinion.
 
  American Appraisal assumed, without independent verification, that the pro
forma balance sheet and financial analyses provided to American Appraisal have
been reasonably prepared and reflect the best available estimates, at the time
they were prepared, of the future financial results and condition of the
Company and United, and that there has been no material adverse change in the
assets, financial condition, business or prospects of the Company and United
since the date of the most recent financial statements made available to
American Appraisal. American Appraisal stated that nothing has come to its
attention that would lead it to believe that the foregoing assumption is
unreasonable.
 
  Although American Appraisal did not independently verify the accuracy and
completeness of the Status Quo Scenario C and forecasts, or any of the
assumptions, estimates or judgments referred to therein, or the basis therefor,
and although no assurances can be given that such Status Quo Scenario C and
forecasts can be realized or that actual results will not vary materially from
those projected, American Appraisal stated that nothing had come to its
attention during the course of its engagement that lead it to believe that any
information reviewed by it or presented to it in connection with its rendering
of the American Appraisal Opinion is unreasonable or inaccurate in any material
respect or that it was unreasonable for it to utilize and rely upon the
financial analyses, financial statements, assumptions, description of the
business and liabilities, estimates and judgments or statements of the
managements of the Company and United and their respective counsel, accountants
and financial advisors. The American Appraisal Opinion is necessarily based on
business, economic, market and other conditions as they existed at the time of
the opinion and as they could be evaluated by American Appraisal at such time.
 
  The American Appraisal Opinion stated that, based upon and subject to the
conditions and assumptions contained therein, (a) the fair value of the
aggregate assets of each of the Company (on a consolidated basis) and United
(on a consolidated basis) will exceed their total respective liabilities
(including, without limitation, subordinated, unmatured, unliquidated and
contingent liabilities), (b) the present fair salable value of the aggregate
assets of each of the Company (on a consolidated basis) and United (on a
consolidated basis) will be greater than their respective probable liabilities
on their debts as such debts become absolute and matured, (c) each of the
Company (on a consolidated basis) and United (on a consolidated basis) will be
able to pay their respective debts and other liabilities, including contingent
liabilities and other commitments, as they mature, (d) the capital remaining in
each of the Company (on a consolidated basis) and in United (on a consolidated
basis) after consummation of the Recapitalization will not be unreasonably
small for the businesses in which the Company and United are engaged, as
management of the Company and United has indicated such businesses are
conducted and as management has indicated the businesses are proposed to be
conducted following the consummation of the Recapitalization, and after giving
due consideration to the prevailing practices in the industry in which the
Company and United will be engaged, (e) the excess of the
 
                                       41
<PAGE>
 
   
fair value of the total assets of the Company over the total liabilities,
including contingent liabilities, of the Company, is equal to or exceeds the
value of the Recapitalization Consideration to stockholders plus the stated
capital of the Company and (f) the excess of the fair value of the total assets
of United over the total liabilities, including contingent liabilities, of
United, is equal to or exceeds the value of the stated capital of United.     
 
  American Appraisal indicated that it believed the excess of total assets over
pro forma liabilities was approximately $2.5 billion at December 31, 1993,
compared to approximately $1.203 billion in stockholders' equity as of such
date, determined according to generally accepted accounting principles, so
that, giving effect to the Recapitalization, the indicated excess assets of the
Company for purposes of Delaware law exceeded $1 billion.
 
  The American Appraisal Opinion will not be binding on creditors of the
Company. Accordingly, there can be no assurance that a court would value the
Company's assets on a going-concern basis in order to determine whether the
Company was insolvent at the time of the Recapitalization or that, regardless
of the method of valuation, a court would not determine that the Company was
insolvent at such time. The Board and management believe that the Debentures
will be incurred by the Company for proper purposes and in good faith, that the
Company will receive reasonably equivalent value or fair consideration for
incurring such indebtedness and that, based on present forecasts and other
financial information, at the time of the Recapitalization, the Company will be
solvent, will have sufficient capital to carry on its business and will be able
to pay its debts as they mature. See "--Certain Revenue and Earnings Scenarios"
and "UNAUDITED PRO FORMA FINANCIAL INFORMATION."
   
  As compensation for its services, American Appraisal received a fee of
$50,000 from the Company upon execution of the engagement agreement and
$110,000 plus expenses upon delivery of the final American Appraisal Opinion
and will receive $20,000 plus expenses upon delivery of the updated opinion. In
addition, the Company agreed to indemnify and hold harmless American Appraisal
in any claim arising from any untrue information furnished by the Company or
from any services relating to the American Appraisal Opinion, except in the
case a loss is found to have resulted from American Appraisal's negligence or
misfeasance or willful or knowing violation of law or breach of the engagement
agreement.     
 
PURPOSE AND STRUCTURE OF THE RECAPITALIZATION
   
  The purpose of the Recapitalization is to recapitalize the Company and
thereby provide the holders of Old Shares with an opportunity to receive cash
or a combination of cash, Debentures and Depositary Preferred Shares
representing interest in Public Preferred Stock for a portion of their Old
Shares, while permitting the holders of Old Shares to retain a significant
ongoing equity interest in a Company that is expected to have a lower cost
structure and be more competitive and to provide performance incentives to the
Company's employees by providing them with significant equity participation in
the Company through the ESOPs. The Recapitalization is being effected at the
present time because the Board believes that it is the best available
alternative to maximize value to the Company's stockholders while achieving
significant wage concessions and work-rule changes that the Board believes are
necessary to position United to compete in the aviation marketplace. See
"BACKGROUND OF THE PLAN OF RECAPITALIZATION" and "--Recommendation of the
Board."     
   
  The use of shares of Redeemable Preferred Stock has been chosen in order to
comply with technical aspects of Delaware law that may be applicable to the
Recapitalization. The Company does not intend to send certificates for
Redeemable Preferred Stock to the holders of Old Shares, and, in lieu thereof,
cash (if the Offerings are consummated) or cash, Debentures and Depositary
Preferred Shares (if the Offerings are not consummated) will be paid based upon
the number of shares of Redeemable Preferred Stock issued in the
Reclassification and the redemption price per one one-thousandth of a share of
Redeemable Preferred Stock.     
 
 
                                       42
<PAGE>
 
   
  It is expected that if the Plan of Recapitalization is not approved by the
Company's stockholders, or if the Recapitalization is not consummated for any
other reason, the Company's current management, under the direction of the
Board, will continue to manage the Company as an ongoing business. In such
event, management would take other actions intended to achieve a lower cost
structure intended to allow the Company to compete effectively in the global
aviation marketplace, which may include actions described in this Proxy
Statement/Prospectus relating to the "enhanced status quo" alternative or
Fundamental Restructuring Plan described under "BACKGROUND OF THE PLAN OF
RECAPITALIZATION."     
 
INTERESTS OF CERTAIN PERSONS IN THE RECAPITALIZATION
 
  In considering the Plan of Recapitalization, stockholders should be aware
that the executive officers and the Board members have certain interests,
described below, that present them with potential conflicts of interest in
connection with the Recapitalization. The Board was aware of these potential
conflicts and considered them among the other matters described under "--
Recommendation of the Board."
   
  The transactions contemplated by the Plan of Recapitalization will constitute
a "change in control" under the Employment Agreements (as defined below) with
Messrs. Wolf and Pope, the severance agreements entered into by United with all
other executive officers, the 1988 Restricted Stock Plan, and the 1981 Stock
Program as well as the Retirement Plan for outside directors and its related
trust. See "CERTAIN INFORMATION CONCERNING THE BOARD OF DIRECTORS--Compensation
of Directors; Effect of "Change in Control' " and "EXECUTIVE COMPENSATION--
Employment Contracts and Change in Control Arrangements."     
   
  The Plan of Recapitalization provides that Messrs. Wolf, Pope and Nagin will
retire from all positions they hold with the Company and all of its
subsidiaries at or immediately prior to the Effective Time and that no other
officer of the Company or United may be terminated for a period of six months
following the Effective Time unless such termination is approved by at least
two Outside Public Directors (as defined below, see "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Public Directors") and the
Chief Executive Officer (the "CEO") of the Company (Mr. Greenwald).     
 
  Pursuant to agreements originally entered into upon the commencement of their
employment in 1987, 1988 and 1988, respectively, with the Company and United as
subsequently amended (the "Officer Agreements"), upon their retirements in
accordance with the Plan of Recapitalization, each of Messrs. Wolf, Pope and
Nagin will be entitled to receive: (1) a cash payment (based on a multiple of
three times current salary and deemed bonus) equal to approximately $4.3
million, $1.8 million and $1.1 million, respectively, (2) lifetime travel
privileges (and reimbursement of related taxes, with certain limitations in Mr.
Nagin's case) on United for each of them and their spouses and other eligible
dependents, (3) continued coverage under United's medical and other welfare
benefit plans (limited to three years in Mr. Pope's case) and (4) certain other
benefits, including certain pension-related benefits, see "EXECUTIVE
COMPENSATION--Pension Plan Table."
   
  The 1988 Restricted Stock Plan provides that all restricted shares awarded
thereunder shall vest upon the occurrence of a "change in control." As of May
16, 1994, Messrs. Wolf, Pope, Nagin, Guyette, O'Gorman and George beneficially
own 10,000, 26,500, 13,000, 11,000, 7,500 and 10,200 restricted shares,
respectively.     
   
  Options to acquire Old Shares awarded under the 1981 Stock Program held by
executive officers become exercisable in connection with the occurrence of a
"change in control." Upon consummation of the transactions contemplated by the
Plan, each such Option will automatically be converted into an option to
acquire one half (0.5) of a New Share and (a) if the Offerings are consummated,
one one-thousandth of a share of Series E Redeemable Preferred Stock, without
par value, of the Company, which one one-thousandth of a share will be redeemed
immediately after issuance, for an amount of cash equal to the sum of (i)
$25.80, (ii) the proceeds (without deducting the underwriting discount or other
costs) from the sale by United of $15.55 face amount of Series A Debentures and
$15.55 face amount of Series B Debentures and (iii) the     

                                       43
<PAGE>
 
   
proceeds (without deducting the underwriting discount or other costs) from the
sale by the Company of 1.244 Depositary Preferred Shares representing
interests in $31.10 liquidation preference of Public Preferred Stock (under
various circumstances the proceeds of the sale of the Debentures and the
Depositary Preferred Shares could be less than their face amount) or (b) if
the Offerings are not consummated, one one-thousandth of a share of Series D
Preferred Stock, which one one-thousandth of a share will be redeemed
immediately after issuance for (i) $25.80 in cash, (ii) $15.55 face amount of
Series A Debentures, (iii) $15.55 face amount of Series B Debentures and (iv)
1.244 Depositary Preferred Shares representing interests in $31.10 liquidation
preference of Public Preferred Stock. As of May 31, 1994, Messrs. Wolf, Pope,
Nagin, Guyette, O'Gorman and George held such Options (with an exercise price
of $131 or less) to purchase respectively 125,000 Old Shares (all of which are
exercisable as of May 31, 1994 and with an average exercise price of $89.99)
150,000 Old Shares, (all of which are exercisable as of May 31, 1994 with an
average exercise price of $95.81), 60,000 Old Shares (45,000 of which are
exercisable as of May 31, 1994 and 15,000 of which will become exercisable
immediately prior to the Effective Time and with an average exercise price of
$107.85), 82,120 Old Shares (67,120 of which are exercisable as of May 31,
1994 and 15,000 of which will become exercisable immediately prior to the
Effective Time and with an average exercise price of $101.59), 30,000 (15,000
of which are exercisable as of May 31, 1994 and 15,000 of which will become
exercisable immediately prior to the Effective Time and with an average
exercise price of $124) and 56,250 Old Shares (41,250 of which are exercisable
as of May 31, 1994 and 15,000 of which will become exercisable immediately
prior to the Effective Time and with an average exercise price of $108.69). In
addition, Messrs. Wolf, Pope and O'Gorman hold such Options to purchase
225,000, 60,000 and 30,000 Old Shares at prices in excess of $131.     
   
  The Company has amended the 1988 Restricted Stock Plan, the 1981 Stock
Program and the Incentive Plan, in each case, subject to stockholders'
approval and consummation of the transactions contemplated by the Plan of
Recapitalization. Each of the amendments is intended to permit awards under
the related plan to continue to be deductible by the Company for Federal
income tax purposes under Section 162(m) of the Internal Revenue Code. In
addition, the amendment to the 1981 Stock Program reserves an additional
1,200,000 New Shares (subject to increase in the event of an adjustment
relating to the New Shares described in "THE PLAN OF RECAPITALIZATION--
Establishment of ESOPs--Additional Shares") for issuance upon the exercise of
options granted thereunder, and the amendment to the Incentive Plan permits
each participant to elect to defer all or any portion of any bonus otherwise
payable thereunder.     
 
  See "CERTAIN INFORMATION CONCERNING THE BOARD OF DIRECTORS--Compensation of
Directors; Effect of "Change in Control' " for certain information with
respect to the effect of the Recapitalization on benefits provided to members
of the Company's Board.
   
  See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--Fees and Expenses;
Indemnification" for certain information with respect to indemnification and
insurance coverage to be provided by the Company to, among others, directors
and executive officers of the Company following the Effective Time.     
 
CERTAIN RISK FACTORS
   
  In addition to the other information contained in this Proxy
Statement/Prospectus, holders of Old Shares should carefully consider the
following risk factors concerning the New Shares, the Debentures and the
Depositary Preferred Shares representing interests in the Public Preferred
Stock.     
   
  Financial Effects; Delaware Law Considerations. The Recapitalization will
immediately change the Company's capitalization to one that is more highly
leveraged. In this regard, the following discussion compares the pro forma
book effect of the Recapitalization on long-term debt, stockholder's equity
and income/loss from continuing operations with recent historical financial
information of the Company. On a pro forma book basis at March 31, 1994, the
Company would have had approximately $3.451 billion of long-term debt and a
deficit of approximately $448 million of stockholders' equity as compared to
the approximately $2.693 billion of long-term debt and approximately $1.097
billion of stockholders' equity that was shown on the Company's balance     
 
                                      44
<PAGE>
 
   
sheet on such date. In addition, if the Recapitalization had occurred as of
January 1, 1993, the Company would have reported, on a pro forma basis, income
from continuing operations of approximately $38 million for the year ended
December 31, 1993 and a loss from continuing operations of approximately $58
million for the three months ended March 31, 1994, as compared to losses from
continuing operations of $31 million for the year ended December 31, 1993 and
$71 million for the three months ended March 31, 1994 that were reported for
each period. See "UNAUDITED PRO FORMA FINANCIAL INFORMATION."     
   
  The Company's earnings were inadequate to cover fixed charges and preferred
stock dividends by $98 million in 1993, by $748 million in 1992 and by $599
million in 1991. On a pro forma basis, the Company's earnings in 1993 were
inadequate to cover fixed charges and preferred stock dividends by $109
million. In addition, the Company's ratio of earnings to fixed charges was
inadequate to cover fixed charges and preferred stock dividends for the three
month period ended March 31, 1994 by $118 million, and on a pro forma basis
they were inadequate by $97 million. United's earnings were inadequate to
cover fixed charges by $77 million in 1993, by $694 million in 1992 and by
$604 million in 1991. On a pro forma basis, United's earnings in 1993 were
inadequate to cover fixed charges by $63 million. In addition, United's
earnings were inadequate to cover fixed charges for the three month period
ended March 31, 1994 by $130 million, and on a pro forma basis they were
inadequate by $102 million. Non-cash depreciation and amortization are
deducted in computing earnings before fixed charges. Such non-cash charges do
not significantly affect the ability of United to fund operations, service
debt, or provide funds to service the Company's preferred stock dividends.
Depreciation and amortization of United were $722 million in 1993, $695
million in 1992, $604 million in 1991 and $178 million for the three month
period ended March 31, 1994.     
   
  The Delaware General Corporation Law (the "DGCL") requires that the payments
to holders of Old Shares in the Recapitalization be made from "surplus." For
purposes of Delaware law, surplus equals the excess, if any, at any given
time, of the net assets of the corporation over stated capital. Valuation of
the Company's assets at their fair value (as supported by the American
Appraisal Opinion referred to above) would create capital surplus that under
the DGCL may be used for such payments. In addition, such payments would not
be permitted if after giving effect to them the Company would not be able to
pay its debts as they become due in the usual course of business. The Board
believes that the Company will be able to pay such debts, based in part on the
revenue and earnings scenarios set forth above under "--Certain Revenue and
Earnings Scenarios" and on the American Appraisal Opinion referred to above.
See "THE PLAN OF RECAPITALIZATION--Terms and Conditions," and "UNAUDITED PRO
FORMA FINANCIAL INFORMATION." Given the more leveraged financial structure of
the Company following the Recapitalization, certain industry risks could have
a greater adverse impact on the Company after the Recapitalization than might
have been the case prior to the Recapitalization.     
   
 Governance Structure     
   
  Although the Company has attempted to achieve a balanced approach to its
corporate governance structure after the Recapitalization, such structure is
very unusual in the management of a large, complex public corporation, and it
is not certain that the actual operation of the corporate governance process
will not result in disputes or inability to achieve results that are in the
best interests of the Company or holders of New Shares.     
   
  Following consummation of the Recapitalization and until the Sunset, the
Board will be comprised of twelve members elected as follows: (i) five public
directors ("Public Directors") elected by holders of the New Shares including
(a) three members of the existing Board or other individuals who previously
had no material contact with the Company other than as directors and (b) two
substantially full-time employees of the Company intended to be the CEO and an
additional senior executive of the Company, (ii) four independent directors
elected by the initial independent directors intended to be a quasi self-
perpetuating body, (iii) three directors representing various employee groups
elected as follows: (a) one director elected by the ALPA-MEC, (b) one director
elected by the IAM or its designee (the director elected by the ALPA-MEC and
the director elected by the IAM or its designee are referred to collectively
as the "Union Directors") and (c) one     
 
                                      45
<PAGE>
 
   
director (the "Salaried and Management Director" and, with the Union
Directors, the "Employee Directors") elected by holders of the Class SAM
Preferred Stock (the Salaried and Management Director and an additional
designated stockholder). Generally, approval of ordinary Board actions will
require a majority vote of the votes present at a meeting at which a quorum is
present and approval of certain extraordinary matters will require, subject to
certain exceptions, approval of either three-quarters of the Board (including
the concurrence of one Union Director) or three-quarters of the shares present
and voting at a stockholders' meeting at which a quorum is present. In
addition, certain extraordinary matters will require approval of the Public
Directors, the Independent Directors or a majority of shares not held by the
ESOPs. The following Committees will be constituted: the Audit Committee, the
Competitive Action Plan ("CAP") Committee, the Compensation Committee, the
Compensation Administration Committee, the Executive Committee, the
Independent Director Nomination Committee, the Labor Committee, the Outside
Public Director Nomination Committee and the Transaction Committee. Public
directors and independent directors will be represented on all committees and
the Employee Directors will be represented on the Executive Committee, the CAP
Committee, the Independent Director Nomination Committee and the Compensation
Committee. See, "THE PLAN OF RECAPITALIZATION-- Revised Governance Structure".
    
   
  Under the terms of the Restated Certificate, the participants in the ESOPs
(and in certain circumstances the ALPA-MEC, the IAM and the Salaried and
Management Director ) will continue to hold more than 50% of the voting power
of the Company until the economic equity interest held by or credited to the
ESOPs and other employee benefit plans sponsored by the Company is less than
20% of the common equity of the Company, all as more fully described in "THE
PLAN OF RECAPITALIZATION--Revised Governance Structure--Sunset." The
termination of the right to exercise more than 50% of the voting power of the
Company is referred to herein as the "Sunset." See "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Sunset." Under current
actuarial assumptions, the Company estimates that this Sunset provision will
not become operative until 2016 if additional purchases are not made by
eligible employee benefit plans. However, such plans will have the right, and
may be expected to, make additional purchases, thereby delaying the occurrence
of the Sunset. In addition, the Restated Certificate contains a number of
provisions which may prevent the Company prior to the Sunset from taking
certain specified actions without the consent of one or both of the members of
the Board elected by ALPA and the IAM or a 75% vote of holders of New Shares
and Voting Preferred Stock. See "THE PLAN OF RECAPITALIZATION--Revised
Governance Structure."     
 
 Fraudulent Conveyance
   
  If a court in a lawsuit by an unpaid creditor or representative of
creditors, such as a trustee in bankruptcy, were to find that, at the time the
Company distributed to holders of Old Shares the cash and Debentures that such
holders are to receive in the Recapitalization, the Company (i) was insolvent,
(ii) was rendered insolvent by reason of such distributions, (iii) was engaged
in a business or transaction for which the assets remaining with the Company
constituted unreasonably small capital to carry on its business or (iv)
intended to incur, or believed that it would incur, debts beyond its ability
to pay as such debts matured, such court may void the distributions to
stockholders and require that such holders return the same (or equivalent
amounts) to the Company or to a fund for the benefit of its creditors. If a
court were to make similar findings about United's issuance of the Debentures,
such court could avoid United's obligations under the Debentures or order the
Debentures to be subordinated to all existing and future indebtedness of
United.     
   
  The measure of insolvency for purposes of the foregoing would vary depending
upon the law of the jurisdiction that was being applied. Generally, however,
the Company would be considered insolvent if at the time of the
Recapitalization the fair value of the Company's assets is less than the
amount of the Company's total debts and liabilities or if the Company has
incurred debt beyond its ability to repay as such debt matures. As described
in "SPECIAL FACTORS--Opinion of Valuation Firm," the American Appraisal
Opinion was rendered orally to the Board at the March 14, 1994 meeting and in
a written opinion to the Board and the Company dated as of March 14, 1994. In
rendering the American Appraisal Opinion, American Appraisal     
 
                                      46
<PAGE>
 
valued the assets of the Company (on a consolidated basis) and United (on a
consolidated basis), as going concerns, both immediately before and after, and
giving effect to, the Recapitalization. The valuation included the aggregate
assets of the business enterprise of each of the Company (on a consolidated
basis) and United (on a consolidated basis), or total invested capital as
represented by the total net working capital, tangible plant, property and
equipment and intangible assets of the respective business enterprises.
American Appraisal stated that it believed this to be a reasonable basis on
which to value the Company and United and that nothing has come to its
attention that caused it to believe that each of the Company (on a consolidated
basis) and United (on a consolidated basis), before and after the
Recapitalization, will not be going concerns.
   
  As stated in "SPECIAL FACTORS--Opinion of Valuation Firm," the American
Appraisal Opinion stated that, based upon and subject to the conditions and
assumptions contained therein, (a) the fair value of the aggregate assets of
each of the Company (on a consolidated basis) and United (on a consolidated
basis) will exceed their total respective liabilities (including, without
limitation, subordinated, unmatured, unliquidated and contingent liabilities),
(b) the present fair salable value of the aggregate assets of each of the
Company (on a consolidated basis) and United (on a consolidated basis) will be
greater than their respective probable liabilities on their debts as such debts
become absolute and matured, (c) each of the Company (on a consolidated basis)
and United (on a consolidated basis) will be able to pay their respective debts
and other liabilities, including contingent liabilities and other commitments,
as they mature, (d) the capital remaining in each of the Company (on a
consolidated basis) and in United (on a consolidated basis) after consummation
of the Recapitalization will not be unreasonably small for the businesses in
which the Company and United are engaged, as management of the Company and
United has indicated such businesses are conducted and as management has
indicated the businesses are proposed to be conducted following the
consummation of the Recapitalization, and after giving due consideration to the
prevailing practices in the industry in which the Company and United will be
engaged, (e) the excess of the fair value of the total assets of the Company
over the total liabilities, including contingent liabilities, of the Company,
is equal to or exceeds the value of the Recapitalization Consideration to
stockholders plus the stated capital of the Company and (f) the excess of the
fair value of the total assets of United over the total liabilities, including
contingent liabilities, of United, is equal to or exceeds the value of the
stated capital of United.     
 
  American Appraisal also indicated that it believed the excess of total assets
over pro forma liabilities was approximately $2.5 billion at December 31, 1993,
compared to approximately $1.203 billion in stockholders' equity as of such
date, determined according to generally accepted accounting principles, so
that, giving effect to the Recapitalization, the indicated excess assets of the
Company for purposes of Delaware law exceeded $1 billion.
 
 Certain Anti-takeover Effects
   
  Certain provisions of the governance structure will make it extremely
difficult to acquire the Company in a transaction that was not approved by at
least one of the Union Directors or 75% of the vote of the New Shares and the
Voting Preferred Stock (as defined below, see "DESCRIPTION OF THE SECURITIES--
The Voting Preferred Stock--General."), even if such transaction might be
beneficial to the Company's stockholders. In particular, the provision
described below in "THE PLAN OF RECAPITALIZATION--Revised Governance
Structure--Nondilution" will prevent the occurrence of an acquisition of the
Company for an extended period following the Effective Time if the holders of
over 90% of the Voting Preferred Stock disapprove such acquisition.     
   
 Pricing of Public Preferred Stock and Debentures     
       
   
  Pricing of Public Preferred Stock and Debentures. As described in "THE PLAN
OF RECAPITALIZATION--Terms and Conditions--Pricing of the Securities," the
final interest rates on the Debentures and the final dividend rate on the
Public Preferred Stock will be established shortly before the Meeting. Although
the procedure for establishing such final rates is designed to determine the
rates that such securities should bear for the Debentures and the Depositary
Preferred Shares representing interests in the     
 
                                       47
<PAGE>
 
   
Public Preferred Stock to trade at par assuming such securities were fully
distributed, the Plan of Recapitalization provides that such rates may not
exceed certain caps. If the Offerings are consummated, the interest rates on
the Debentures and the dividend rate on the Preferred Stock may be adjusted
(including in excess of their respective caps) to permit the Debentures and the
Depositary Shares to be sold at or closer to par, but if that is done, the
principal amount of the series of Debentures affected or the number of
Depositary Preferred Shares representing the Public Preferred Stock, as the
case may be, will be reduced so that the aggregate amount of interest payable
annually by United on the Series A Debentures or the aggregate amount of
dividends payable annually by the Company on the Public Preferred Stock will
not exceed certain maximum amounts calculated with reference to such caps. The
underwriting agreements for the Offerings are expected to provide that if the
Offerings are not consummated, the interest rates borne by the Debentures and
the dividend rate borne by the Public Preferred Stock will be subject to the
caps. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--Pricing the
Securities." If the prevailing market interest and dividend rates for
securities comparable to the Debentures and the Public Preferred Stock are
higher than the rate caps applicable to the Debentures or the Public Preferred
Stock, as the case may be, the Debentures or the Depositary Preferred Shares
representing interests in the Public Preferred Stock, as the case may be, may
trade at a discount to par. Accordingly, if the rate caps are imposed for
either or both series of the Debentures or the Depositary Preferred Shares, (a)
the proceeds from the Offerings, if the Offerings are consummated, would be
less than the face amount thereof, or (b) if the Offerings are not consummated,
the securities constituting a part of the Mixed Recapitalization Consideration
would have a trading value of less than the face amount thereof. Based on the
current general market conditions, the Company believes that the rates for
either or both series of the Debentures or the Depositary Preferred Shares may
approach or exceed the maximum rates.     
 
 Investment Values; Future Investments
   
  Cost savings envisioned by the agreements with ALPA and the IAM and the
anticipated productivity increases discussed herein are estimates prepared by
the Company for analytical purposes. Such cost savings and anticipated
productivity increases could be difficult to achieve, and, even if all proposed
plans for employee investments are implemented, the value of the reductions in
wages and benefits and work-rule changes and anticipated productivity increases
may not be as significant as currently calculated. Mandated job guarantees may
make it difficult to achieve significant additional productivity improvements,
and, if additional reductions in wages and benefits and work-rule changes
become desirable in management's view, such reductions in wages and benefits
and work-rule changes may be more difficult to achieve in light of the long-
term nature of the revised collective bargaining agreement with ALPA and the
IAM that constitute elements of the Recapitalization (the "Collective
Bargaining Agreements").     
   
 Lack of Employee Consensus     
   
  Certain employee groups may not be in favor of the changes arising from the
Recapitalization and may react in a manner that does not facilitate achievement
of the desired results. For example, the AFA has declined to date to
participate in the transaction, certain other employees who will be
participating in the wage and benefit reductions and work-rule changes were not
in favor of the transaction, and certain union organizing activity, based on
opposition to certain aspects of the transaction, has occurred. This lack of
consensus may reduce the value of the increased employee commitments the
Company expects to achieve by virtue of the Recapitalization.     
 
 Management Change
 
  The current Chairman and Chief Executive Officer of the Company, Mr. Stephen
M. Wolf, President, Mr. John C. Pope, and Executive Vice President--Corporate
Affairs and General Counsel, Mr. Lawrence M. Nagin, will retire at the
Effective Time. The new chief executive officer selected by ALPA and the IAM,
Mr. Gerald M. Greenwald, will be required to implement reductions in wages and
benefits and work-rule changes that he did not directly negotiate in an
industry in which he has not previously been engaged. In
 
                                       48
<PAGE>
 
addition, it is possible that the Company may face attrition by officers and
other members of management and that the Company's new senior management may
face difficulties in implementing strategies or attracting additional
management employees.
 
 Reduced Flexibility
   
  The corporate governance structure and Collective Bargaining Agreements with
ALPA and the IAM may inhibit management's ability to alter strategy in a
volatile, competitive industry. Among the more significant constraints are (i)
a prohibition on domestic code sharing in excess of 1% of domestic block
hours, excluding several small existing agreements, without ALPA's consent,
(ii) a no layoff promise for all currently employed participating union
employees during the five- to six-year investment period and, for pilots,
while U2 remains in operation (which constraint is ameliorated as normal
attrition reduces the impact of the no-layoff promise), (iii) restrictions on
international code sharing, unless the Company can demonstrate that
international code sharing arrangements do not cause a reduction in
international flying and as long as the Company does not expand code sharing
once the Company reduces international flying below a certain level and (iv)
an agreement not to sell the Company's Denver pilot training facility and
certain maintenance facilities. In addition, the Restated Certificate contains
restrictions on the ability of the Company and United to sell assets and issue
equity securities absent certain specified Board or stockholder approvals. In
most circumstances, the issuance of additional equity securities would not be
counted in determining whether the Sunset has occurred.     
   
  Limitations on asset sales and equity issuances included in the Company's
Restated Certificate might make it more difficult to raise cash, even if
management desired to do so to take advantage of a perceived opportunity.     
 
 Implementation of U2
   
  Although the Company expects to develop U2 as an important component of its
competitive posture and has ascribed a significant portion of the value of the
Recapitalization to the ability to implement U2, no assurance can be given
that the Company will be able to do so effectively or to realize the financial
benefits expected to be received by the Company from the implementation of U2.
The success of U2 will be based not only upon the nature of the Company's
business plan but also upon the strategies and plans implemented by existing
low-cost competitors and by new entrants into the low-cost market. In
addition, even if the business concept of U2 is successful, (i) U2 will
comprise no more than 20% of United's system block hours up to two million
block hours systemwide and no more than 25% of the system block hours in
excess of two million, (ii) U2 can only operate in markets in the lower 48
states with stage lengths up to 750 nautical miles and cannot fly between
United's hub or international gateway cities except for Los Angeles basin--San
Francisco bay area service, which excludes U2 from such heavily traveled
routes as the transcontinental routes and New York/Chicago, Chicago/Denver and
Chicago/Washington Dulles, (iii) U2 cannot operate aircraft larger than a
B737-300 and (iv) for the first six years, U2 can only operate up to 90% of
monthly block hours in markets previously served (within 24 months) by United.
If United's systemwide widebody flying (i.e., flying performed in B-757 or
larger aircraft) falls below (i) 95% of the widebody block hours projected in
the Company's October 1993 fleet plan for any twelve month period from the
Effective Time through 1999 or (ii) a certain minimum level for any twelve
month period between 2000 and 2006, the total flying performed in the U2
operation must be reduced by the shortfall in widebody flying. Even if
implemented as planned, U2 will not have costs which are as low as those of
certain low-cost competitors. U2 must rely upon factors other than lowest cost
to secure market share and be successful.     
 
 Competitive Response
   
  Even if the Company is able to achieve cost reductions and productivity
enhancements, the Company's higher cost competitors may be able to achieve
comparable agreements with their labor groups or otherwise reduce their
operating costs and the Company's low-cost competitors may modify their
operations in response     
 
                                      49
<PAGE>
 
   
to the competitive threat posed by U2 and thus, in each case, may eliminate or
reduce the competitive gain sought by the Company and lead to reductions in
fares and earnings. In this regard, for example, Continental Airlines (which
already has a low cost structure) has implemented a low cost, short haul
service which would be competitive with U2, and Delta has announced its intent
to lower its overall costs substantially. If the Company's higher cost
competitors were to achieve more significant reductions in wages and benefits
and work-rule changes than those achieved by the Company, the Company's
ability to respond to competition would be hampered by the fixed long-term
nature of the agreements that constitute elements of the Recapitalization.
    
 Labor Protective Provisions
 
  The Company will continue in effect, or amend to include, certain provisions
of agreements with ALPA and the IAM that (i) provide certain rights in the
event of a change in control of the Company and (ii) prohibit furloughs,
within certain conditions, if the Company disposes of 25 percent or more of
its assets or assets which produce 25 percent or more of its block hours. The
revised Collective Bargaining Agreements obligate the Company to require any
carrier purchasing route authority or aircraft that produce 25 percent or more
of the Company's operating revenues or block hours to hire an appropriate
number of United employees with seniority credit.
 
 Tax Deductibility of Employee Stock Ownership Plan Contributions and
Dividends
   
  Although the Company has attempted to structure the ESOPs so that all
amounts contributed thereto and dividends paid with respect to the stock held
thereunder will be deductible to the Company for Federal income tax purposes,
there are no regulations governing the deductibility of dividends paid on the
ESOP Preferred Stock and there can be no assurance that one or more current or
future limitations under the Internal Revenue Code will not adversely impact
the deductibility of such amounts and dividends. The deductibility of such
amounts depends, to some extent, on the conclusions set forth in an opinion
rendered to the ESOP Trustee by Houlihan Lokey and there can be no assurance
that the Internal Revenue Service (the "IRS") will agree with the methodology
set forth in such opinion. With respect to tax deductions associated with the
Class 1 ESOP Preferred Stock, the amount of such deductions is directly
related to the purchase prices of the Class 1 ESOP Preferred Stock. See "THE
PLAN OF RECAPITALIZATION--Terms and Conditions--Purchase of ESOP Preferred
Stock." With respect to tax deductions associated with the Class 2 ESOP
Preferred Stock, the amount of such deductions is directly related to the
value of such stock in the future when such deductions will be available to
the Company. For additional information on the tax consequences relating to
the ESOPs, see "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--Federal
Income Tax Matters."     
       
       
 Amendments to Collective Bargaining Agreements; Future Labor Agreements
   
  There can be no assurance that the new management of the Company in the
future will not agree to amend the Collective Bargaining Agreements with ALPA
and the IAM in a manner that reduces or eliminates the cost savings that are
the basis of the Recapitalization. However, any such amendment must be
approved by the Labor Committee of the Board (which will not include any Union
Director (as defined below)). See "THE PLAN OF RECAPITALIZATION--Revised
Governance Structure--Committees." In addition, at the end of the current
employee investment period, there can be no assurance that the Company's labor
agreements will be renegotiated in a manner that continues in subsequent
periods the cost savings that are being sought through the Recapitalization or
that does not reverse the effect of any cost savings that will have been
obtained thereby.     
 
 Possible Effect of Organization of Additional Employees
 
  In the event any portion of the management and salaried employees that are
not currently represented by a union elects union representation pursuant to
the Railway Labor Act, the Company would be obligated
 
                                      50
<PAGE>
 
to bargain with such union over the terms and conditions of employment
applicable to such employees, including the terms, if any, of such employees'
continuing participation in the ESOPs. This obligation to bargain requires the
Company to "exert every reasonable effort" to reach an agreement but does not
require it to agree to any change or particular term or condition sought by
the union. During the period of negotiation, the Company would be entitled to
maintain the then-existing terms of such employees' participation in the
ESOPs.
 
  The ESOPs provide that if any group of employees that are not currently
represented by a union becomes covered by a new collective bargaining
agreement, such group of employees will not be covered under the ESOPs unless
the collective bargaining agreement so provides. Whether any new collective
bargaining agreement would provide for continuing participation in the ESOPs
by such group of employees is a matter that would be subject to mutual
agreement between the Company and the applicable union. The ESOPs provide,
however, that if the terms of any employee's employment no longer reflect all
of the reductions in wages and benefits and work-rule changes set forth in the
Plan of Recapitalization, then such employee shall cease to be covered by the
ESOPs.
   
  As a result, if any new collective bargaining agreement did not reflect the
reductions in wages and benefits and work-rule changes required by the Plan of
Recapitalization for particular employees, the Company could not agree,
without amending the ESOPs, to allow such employees to participate in the
ESOPs. If any currently unrepresented employees ceased to participate in the
ESOPs under such circumstances, the ESOPs, however, provide that the
unrepresented employees remaining in the ESOPs would receive the shares
previously intended for that newly-represented group. The employment terms,
except base pay, for the unrepresented employees remaining in the ESOPs will
be subject to change, at the Company's discretion, so long as the net economic
value of the unrepresented employees' employment terms is not altered.     
 
 Employee Ownership and Influence
   
  No assurance can be given that the Company, which will be subject to
significant influence by employee groups (including through the right to
voting representation in excess of economic equity ownership, Board and Board
committee representation, the requirement of approval of certain matters by a
Union Director or a 75% vote of the holders of New Shares and Voting Preferred
Stock, and participation by Union Directors in the nomination of the
Independent Directors (as defined below, see "THE PLAN OF RECAPITALIZATION--
Revised Governance Structure")), might not take actions that are more
favorable to such employee groups than might be taken by a company that was
not subject to such influence. The corporate governance structure after the
Recapitalization will not, however, relieve the members of the Board of their
fiduciary obligations under the DGCL.     
 
 Effect of Adjustment on Trading
   
  As described under "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--
Additional Shares," the ESOP Preferred Stock which the Company is initially
obligated to issue or credit to the ESOPs is convertible into approximately
55% of the New Shares but, based on the trading prices of the New Shares in
the twelve months after the Effective Time (the "Measuring Period"), may be
increased up to a maximum of approximately 63% of the New Shares. Such
potential additional issuance may adversely limit the trading prices of the
New Shares during the Measuring Period.     
   
 Additional Issuances of Recapitalization Consideration     
   
  United has registered under the Securities Act of 1933 $449,802,200
aggregate principal amount of each series of Debentures and the Company has
registered 35,984,175 Depositary Preferred Shares representing interests in
$899,604,375 aggregate liquidation preference of the Public Preferred Stock.
If the Offerings are not consummated, United and the Company may be required
to issue a larger number of Debentures and     
 
                                      51
<PAGE>
 
   
Depositary Preferred Shares representing interests in Public Preferred Stock in
connection with the exercise of Options in the event holders thereof fail to
use a cashless exercise feature or in connection with the conversion of certain
Convertible Company Securities (as defined below). However, the failure of
Options holders to utilize a cashless exercise feature would have the effect of
increasing the Company's available cash by an amount equal to the aggregate
exercise price. See "DESCRIPTION OF SECURITIES--The Debentures--General" and
"--The Public Preferred Stock--General." If the Offerings are not consummated,
the Company currently intends to register in the future additional securities
issued or distributed following repurchase in the market, to satisfy the
exercise or conversion of Options or Convertible Company Securities.     
 
 Financial Reporting; Market Assessment
   
  The accounting rules governing employers accounting for employee stock
ownership plans require that compensation expense be recorded for the ESOP
Preferred Stock "committed to be released" during an accounting period based on
the fair value of the ESOP Preferred Stock during such period. The difference
between the fair value and the initial recorded cost of the ESOP Preferred
Stock "committed to be released" is recorded as an adjustment to stockholders'
equity. The ESOP Preferred Stock that has been "committed to be released" is
considered to be outstanding in the if-converted earnings per share calculation
for primary and fully diluted earnings per share if the effect is dilutive. The
circular relationship between the employee stock ownership plan accounting
charges and the Company's stock price, coupled with the size of the
contemplated ESOPs, make future earnings difficult to forecast. In addition,
reported book earnings will be depressed in early years due to the mismatch
between the term of employee investments (which increase earnings) of from five
years, nine months to twelve years and the shorter period of only six years
over which employee stock ownership plans accounting charges will occur. While
it is possible that the equity research community and investors may look
through employee stock ownership plan accounting charges, it is also possible
that the trading price of the New Shares may be negatively impacted by such
accounting treatment.     
   
 Possible Cancellation of Facility     
 
  United is a party to a $500 million commercial paper facility through
agreements with United Airlines First Funding Corporation ("First Funding") and
certain banks. As of the date of this Proxy Statement/Prospectus, approximately
$270 million of commercial paper is outstanding thereunder. As a result of
provisions in the Second Amended and Restated Credit Agreement, dated as of
September 20, 1993 (the "Credit Agreement"), among First Funding, Union Bank as
agent and certain other banks, a "change in control" may be deemed to occur as
a result of the Recapitalization, and First Funding may be restricted from
issuing new commercial paper under the Credit Agreement. If the banks elect to
restrict the issuance of new commercial paper, United will need to renegotiate
the Credit Agreement, obtain a replacement facility or rely on its internal
resources. Although United does not expect it to be the case, United may not be
able to renegotiate the Credit Agreement or obtain a replacement facility;
however, United believes its internal resources would be adequate.
       
 Complexity
   
  Given the complex nature of the various provisions affecting the operation of
the Company after the Effective Time, it is possible that the equity research
community and investors may find the Company difficult to evaluate, which may
have the effect of reducing the trading price of the New Shares from levels
that might otherwise prevail. In addition, equity issuances (other than
Permitted Bankruptcy Equity (as defined below, see "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Extraordinary Matters"))
generally will be disregarded when calculating the percentage of Common Equity
(as defined below, see "THE PLAN OF RECAPITALIZATION--Revised Governance
Structure--Sunset") for Sunset purposes, which may negatively impact the market
value of the New Shares and other equity of the Company.     
 
 
                                       52
<PAGE>
 
 Redistribution
   
  If the Offerings are not consummated, in the Recapitalization, holders of Old
Shares (an equity security) will receive Debentures and Depositary Preferred
Shares in addition to New Shares and cash. It is expected that there will exist
a period, perhaps of a lengthy duration, during which certain recipients of
such securities, concluding that the characteristics thereof are not consistent
with their investment criteria, distribute such securities into the
marketplace. During such distribution period, the supply of such securities in
the market may exceed levels that might otherwise prevail, which would likely
have the effect of depressing the price of such securities from levels that
might otherwise prevail if such securities were held solely by persons or
institutions for whom such securities satisfied their investment criteria. In
addition, although the Company expects that it will apply for listing of the
Debentures and the Depositary Preferred Shares on the New York Stock Exchange
Inc. (the "NYSE") , there can be no assurance that at or following the
Effective Time such securities will be listed on the NYSE or any other
securities exchange or that any trading market for the securities will develop.
    
   
 Taxation of Recapitalization to Stockholders     
   
  For United States Federal income tax purposes, the Recapitalization will be a
taxable transaction to public stockholders that are citizens or residents of
the United States. Such a stockholder whose Old Shares are exchanged for the
Recapitalization Consideration in the Recapitalization will realize gain or
loss in the Recapitalization measured by the difference, if any, between (i)
the fair market value of the Recapitalization Consideration received by such
stockholder in the Recapitalization, and (ii) such stockholder's tax basis
in the Old Shares exchanged in the Recapitalization. If the Offerings are
consummated, gain realized by a public stockholder in the Recapitalization will
be recognized, but only to the extent such gain does not exceed the amount of
cash received by such stockholder in the Recapitalization. If the Offerings are
not consummated, gain realized by a public stockholder in the Recapitalization
will be recognized, but only to the extent such gain does not exceed the sum of
(i) the fair market value of the Debentures and (ii) the amount of cash
received by such stockholder in the Recapitalization. If the Offerings are
consummated, the maximum taxable gain associated with the transaction will not
exceed $88 per Old Share, or such lesser amount, if as a result of the
Offerings the amount of cash exchanged in the Recapitalization is less than $88
per Old Share. If the Offerings are not consummated, assuming that the
Debentures have a fair market value of $31.10 per Old Share, the maximum
taxable gain associated with the transaction will not exceed $56.90 per Old
Share (i.e., the sum of the assumed fair market value of the Debentures and the
amount of cash received). The character of any gain recognized by a public
stockholder in the Recapitalization may be ordinary income or capital gain
depending upon whether the receipt of cash (or Debentures and cash) by the
stockholder has the effect of a dividend distribution as to such stockholder or
is treated as a sale or exchange. Any loss realized by a public stockholder in
the Recapitalization will not be recognized. The operation of the basis
allocation rules would provide that any such loss would be effectively carried
over into the basis of the New Shares (and Depositary Preferred Shares if the
Offerings are not consummated) that are received in the Recapitalization.
However, there can be no assurance that any such loss would ultimately be
recognized by any particular stockholder. For a more detailed discussion of the
Federal income tax consequences of the Recapitalization, see "CERTAIN FEDERAL
INCOME TAX CONSEQUENCES."     
 
 Industry Risks
 
  If the Recapitalization is accomplished, certain risks associated with the
aviation industry will continue to face the Company. Given the more leveraged
financial structure of the Company following the Recapitalization, certain of
these industry risks could have a greater adverse impact on the Company after
the Recapitalization than might have been the case prior to the
Recapitalization.
 
 Industry Conditions and Competition
 
  The airline industry is highly competitive and susceptible to price
discounting. United's competitors include major domestic carriers such as
American, Delta, and Northwest, major international carriers such
 
                                       53
<PAGE>
 
as British Airways and Japan Air Lines, and domestic carriers such as
Southwest, Continental and other carriers with lower cost structures. Airline
profit levels are highly sensitive to, and during the last four years have been
significantly impacted by, adverse changes in fuel costs, average yield (fare
levels) and passenger demand. Passenger demand and yields have been adversely
affected by, among other things, the general state of the economy, the Persian
Gulf War and actions taken by carriers with respect to fares. As a result of
this adverse operating environment, from 1990 to 1993 the domestic airline
industry incurred unprecedented losses. During this period, Eastern Air Lines,
Pan American World Airways and Midway Airlines were liquidated, and Continental
Airlines, America West Airlines and Trans World Airlines filed for bankruptcy.
 
  The emergence in recent years of several new carriers, typically with low
cost structures, has further increased the competitive pressures on the major
U.S. airlines. In some cases, the new entrants have initiated or triggered
price discounting. Aircraft, skilled labor and gates at most airports continue
to be readily available to start-up carriers. Although new entrant carriers
generally commence service with only a few city pairs and have a high rate of
failure, the commencement of service by new carriers on United's routes could
negatively impact United's operating results. In addition, certain existing
U.S. domestic carriers compete primarily by offering low-cost air service on
route networks that do not employ hub and spoke systems. These discount air
carriers have significantly affected the yields of major domestic carriers such
as United and, in certain instances, have made certain markets uneconomical for
carriers such as United.
   
  In the spring of 1992, American introduced a new fare structure followed by a
deeply discounted summer sale, steps that were generally matched by other U.S.
airlines (including United), resulting in substantially depressed industry
yields and significant 1992 losses at all major U.S. airlines (with one
exception). American and the rest of the domestic airline industry have
abandoned that pricing structure, and fare levels have increased in 1993 and
early 1994 from 1992 levels. Nonetheless, discounts continue to exist and may
be increased at any time. The introduction of broadly-available, deeply
discounted fares by a major U.S. airline would likely result in lower yields
for the entire industry and could have a material adverse effect on the
Company's operating results.     
 
 Aircraft Fuel
 
  Since fuel costs constitute a significant portion of the Company's operating
costs (approximately 12% during 1993), significant changes in fuel costs would
materially affect the Company's operating results. Fuel prices continue to be
susceptible to, among other factors, political events, and the Company cannot
predict near- or longer-term fuel prices. In the event of a fuel supply
shortage resulting from a disruption of imports or otherwise, higher fuel
prices or curtailment of scheduled service could result. A one cent change in
the cost per gallon of fuel (based on 1993 consumption levels) impacts
operating expense by approximately $2.25 million per month.
 
  In August 1993, the United States increased taxes on fuel, including aircraft
fuel, by 4.3c per gallon. Airlines are exempt from this tax increase until
October 1, 1995. When implemented, this new tax will increase the Company's
annual operating expenses by approximately $75 million based on United's 1993
domestic fuel consumption levels.
 
 Regulatory Matters
 
  In the last several years, the Federal Aviation Administration (the "FAA")
has issued a number of maintenance directives and other regulations relating
to, among other things, collision avoidance systems, airborne windshear
avoidance systems, noise abatement and increased inspection requirements. The
Company expects to continue incurring costs to comply with the FAA's
regulations.
 
  Additional laws and regulations have been proposed from time to time that
could significantly increase the cost of airline operations by, for instance,
imposing additional requirements or restrictions on operations. Laws and
regulations have also been considered from time to time that would prohibit or
restrict the
 
                                       54
<PAGE>
 
ownership and/or transfer of international airline routes or takeoff and
landing slots. Also, the award of international routes to U.S. carriers (and
their retention) is regulated by treaties and related agreements between the
United States and foreign governments, which are amended from time to time. For
example, there are significant aviation issues between the United States and
such foreign governments as Germany, Japan and the United Kingdom that,
depending on their resolution, may significantly impact the Company's existing
operations or curtail potential expansion opportunities in important regions of
the world. The Company cannot predict what laws and regulations will be adopted
or what changes to international air transportation treaties will be effected,
if any, or how they will affect United.
   
 Holding Company Structure     
   
  The Company is a holding company that conducts operations solely through its
subsidiaries, principally United. The Company will rely on dividends from its
subsidiaries to meet its cash requirements, including cash requirements in
connection with dividends on or redemptions of the Public Preferred Stock (and
related Depositary Preferred Shares). As a result of the Recapitalization,
United will have substantial debt in relation to its stockholder's equity, as
determined on a pro forma basis pursuant to the application of generally
accepted accounting principles.     
 
CERTAIN EFFECTS OF THE RECAPITALIZATION
 
  The Recapitalization will significantly increase the Company's long-term
indebtedness, significantly reduce cash reserves and create a substantial
negative balance in stockholders' equity. See "--Certain Risk Factors," "THE
PLAN OF RECAPITALIZATION" and "UNAUDITED PRO FORMA FINANCIAL INFORMATION."
 
  As a result of the Recapitalization, a new corporate governance structure
will be implemented, a new board of directors will be elected and a new chief
executive officer will be appointed. See "--Management Arrangements," "THE PLAN
OF RECAPITALIZATION--Revised Governance Structure" and "ELECTION OF DIRECTORS."
 
  The New Shares will be registered under the Exchange Act, which requires,
among other things, that the Company furnish certain information to its
stockholders and to the Commission and comply with the Commission's proxy rules
in connection with meetings of the Company's stockholders. The Recapitalization
will result in the Old Shares becoming eligible for deregistration under the
Exchange Act.
 
  Although the Company will not meet certain normal requirements for NYSE
listing following the Recapitalization, such as the requirement of a minimum
net worth, the NYSE has informed the Company that it will permit listing
(subject to official notice of issuance) of the New Shares immediately
following consummation of the Recapitalization.
 
  Except for the Plan of Recapitalization, there are no present plans or
proposals that would result in any material extraordinary corporate
transaction, such as a merger, reorganization, liquidation, relocation of
operations, or sale or transfer of a material amount of assets involving the
Company or its subsidiaries, or any material change in the Company's corporate
structure, business or composition of its management of which the current Board
is aware.
 
  The Recapitalization will be accounted for as a redemption of shares that is
not subject to purchase accounting and, therefore, assets and liabilities will
be carried at their historical cost and there will be no increase in goodwill
amortization or other purchase accounting effects (such as increased
depreciation charges) resulting from the Recapitalization that would reduce
earnings.
 
MANAGEMENT ARRANGEMENTS
   
  Under a Retention Agreement, dated as of January 1, 1994 (the "Retention
Agreement"), ALPA and the IAM agreed to employ Mr. Gerald Greenwald as a
consultant with respect to the transactions     
 
                                       55
<PAGE>
 
contemplated by the Plan of Recapitalization. Mr. Greenwald, the former Vice
Chairman of Chrysler Corporation, was previously associated with a transaction
proposed in 1990 by an entity controlled by the Company's three principal
unions, which transaction was terminated in October 1990.
   
  Under the Retention Agreement, Mr. Greenwald is entitled to a consulting fee
of $80,000 per month from January 1994 to the Effective Time and if the
Retention Agreement is terminated under certain circumstances (e.g.,
termination by the Unions without cause), an additional $1 million payment at
the Effective Time. The Retention Agreement contemplates that Mr. Greenwald and
the Company will execute a five-year employment agreement (the "Greenwald
Agreement"), which agreement will become effective at the Effective Time.
Pursuant to the Greenwald Agreement, the Company will pay to Mr. Greenwald at
the Effective Time a fee of $1 million. Under the Greenwald Agreement, Mr.
Greenwald will receive a salary of $725,000 per year, reduced by 8.25%
(equivalent to the salaried and management concession) and a non-guaranteed
target bonus of $725,000 per year, which target bonus will be payable if Mr.
Greenwald's performance is "consistent with the applicable Board Committee's
objectives and directions" and the Company's performance "does not compel" a
lesser bonus. In addition, the applicable Board Committee will take into
account (i) airline industry trends and (ii) the Company's financial
performance (including cumulative profitability since the Effective Time) in
determining the extent of Mr. Greenwald's bonus. Pursuant to the Greenwald
Agreement, Mr. Greenwald will receive options to acquire 200,000 New Shares,
with an exercise price equal to the fair market value of the New Shares on the
day following the Effective Time. Fifty percent of such options will vest at
the Effective Time and the remainder will vest over 5 years. All options and
restricted stock vest on any termination of Mr. Greenwald's employment other
than termination by the Company for cause or a voluntary resignation. The
options, to the extent vested, will remain outstanding for 10 years,
notwithstanding termination of Mr. Greenwald's employment for any reason,
including "cause". Mr. Greenwald will also receive 50,000 New Shares of
restricted stock, vesting 50% at the Effective Time and the remaining 50% over
5 years. Additional options and restricted stock will be issued to the extent
the equity adjustment mechanism is triggered. See "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Additional Shares."     
 
  The Greenwald Agreement also entitles Mr. Greenwald to an annual pension
equal to the greater of the pension that would accrue under Company plans with
credit for 30 years of service or $500,000 per year. Such pension is payable at
any time elected by Mr. Greenwald following retirement or termination of
employment. Mr. Greenwald's retirement benefit will continue to be paid to his
spouse at 67% of his benefit level under a joint survivor annuity. The
Retention Agreement specifies that benefits under such pension must be funded
in full at the Effective Time through a trust at an estimated amount of $6.4
million.
 
  If Mr. Greenwald's employment is terminated by the Company without "cause" or
by him for "good reason", his salary and guaranteed $725,000 bonus will
continue for 3 years (or, if greater, the remainder of the 5 year contract
term). Generally, the Company will not be entitled to a deduction for Federal
income tax purposes with respect to the amounts described above to the extent
that such amounts exceed $1 million in any year.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  Skadden, Arps, Slate, Meagher & Flom has served as tax counsel to the Company
in connection with the Recapitalization. The following expresses Skadden, Arps,
Slate, Meagher & Flom's opinion to the Company as to the material Federal
income tax consequences that, under currently applicable law, should arise from
the Recapitalization. The following discussion is applicable only to public
stockholders who are citizens or residents of the United States and are not
foreign corporations. The discussion may not be applicable with respect to Old
Shares acquired as compensation, including Old Shares acquired upon the
exercise of options or Old Shares held under the Company's employee benefit
plans, or to Old Shares held as other than capital assets. Moreover, the
discussion is not applicable to public stockholders who hold, or who are
related within the meaning of Section 318 of the Internal Revenue Code to
stockholders who hold,
 
                                       56

employee stock options of the Company. Furthermore, state and local tax
consequences of the Recapitalization are not addressed in the discussion.
Stockholders should note that the opinions of Skadden, Arps, Slate, Meagher &
Flom are not binding on the IRS or any court, and the Company has not sought,
and does not intend to seek, a ruling from the IRS as to the Federal income tax
consequences of the Recapitalization.     
 
  STOCKHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE
APPLICATION OF THE FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATION, AS
WELL AS TO THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL, OR FOREIGN TAX
LAWS TO WHICH THEY MAY BE SUBJECT.
 
  1.  The Recapitalization taken as a whole will constitute a
"recapitalization" of the Company within the meaning of Section 368(a)(1)(E) of
the Internal Revenue Code. Accordingly, the Recapitalization will not be a
taxable transaction to the Company, but will be a taxable transaction to the
public stockholders with the consequences described below.
   
  2.  A public stockholder whose Old Shares are exchanged for the
Recapitalization Consideration in the Recapitalization will realize gain or
loss in the Recapitalization measured by the difference, if any, between (i)
the fair market value of the Recapitalization Consideration received by such
stockholder in the Recapitalization, and (ii) such stockholder's tax basis in
the Old Shares exchanged in the Recapitalization. If the Offerings are
consummated as contemplated, gain realized by a public stockholder in the
Recapitalization will be recognized, but only to the extent such gain does not
exceed the amount of cash received by such stockholder in the Recapitalization.
If the Offerings are not consummated, gain realized by a public stockholder in
the Recapitalization will be recognized, but only to the extent such gain does
not exceed the sum of (i) the fair market value of the Debentures at the
Effective Time and (ii) the amount of cash received by the stockholder in the
Recapitalization. If the Offerings are consummated, any gain in excess of the
cash received (or, if the Offerings are not consummated, the sum of (i) the
fair market value of the Debentures at the Effective Time and (ii) the amount
of cash received by a public stockholder in the Recapitalization), and any loss
realized by a public stockholder in the Recapitalization will not be
recognized. The operation of the basis allocation rules would provide that any
such loss would be effectively carried over into the basis of the New Shares
(and Public Preferred Stock (as represented by Depositary Preferred Shares) if
the Offerings are not consummated) that are received in the Recapitalization.
However, there can be no assurance that any such loss would ultimately be
recognized by any particular stockholder. Stockholders that may realize a loss
on the Recapitalization should consult their own tax advisors regarding the
application of these rules and the recognition of any loss.     
   
  3.  The character of any gain recognized by a public stockholder in the
Recapitalization will depend upon whether the receipt of cash (or Debentures
and cash) by the stockholder has the effect of a dividend distribution as to
such stockholder or is treated as a sale or exchange. If the exchange of Old
Shares for cash (or Debentures and cash) is treated as a sale or exchange, any
gain recognized will be capital gain that, in general, will be long-term
capital gain if the Old Shares have been held for more than one year at the
Effective Time and short-term capital gain if the Old Shares have been held for
one year or less at such time.     
   
  Section 302 of the Internal Revenue Code provides guidance as to whether a
distribution has the effect of the distribution of a dividend. Under Section
302, a distribution will not have the effect of the distribution of a dividend,
and any gain recognized will be capital gain rather than a dividend, if the
distribution is not "essentially equivalent to a dividend" or one of several
other tests is satisfied. Section 318 of the Internal Revenue Code applies to
all of these tests. Under Section 318, a stockholder is deemed to own
constructively Old Shares and New Shares (and possibly shares of Public
Preferred Stock (as represented by Depositary Preferred Shares)) that are
actually owned, and in some cases constructively owned, by certain related
individuals and entities or that may be acquired by such stockholder or such
related individuals or entities by option or conversion, including through
employee stock options. Furthermore, the Section 302 tests are applied after
taking into account any related transactions that are part of a single
integrated plan. Thus, the issuance of the ESOP Preferred Stock and Voting
Preferred Stock to the ESOP pursuant to the     
 
                                       57
<PAGE>
 
   
Recapitalization will be treated as part of a single integrated
recapitalization plan, and it is possible that dispositions or acquisitions by
a public stockholder of Old Shares or New Shares (or possibly Public Preferred
Stock (as represented by Depositary Preferred Shares)) contemporaneous with the
Recapitalization may be considered to be part of the same integrated plan.     
   
  A public stockholder that does not acquire additional Old Shares or New
Shares (or possibly Public Preferred Stock) in a transaction that may be
integrated with the Recapitalization (a "Qualified Public Stockholder") will be
entitled to capital gain treatment if, under all of the facts and
circumstances, the exchange results in a "meaningful reduction" of the
Qualified Public Stockholder's proportionate stock interest in the Company. In
general, for a stockholder's proportionate interest in the Company to undergo a
meaningful reduction, such stockholder must experience a reduction in interests
in one or more of the following areas: (i) control of the Company through
voting, (ii) earnings of the Company through dividends, and (iii) assets of the
Company upon liquidation. Based upon a published ruling of the IRS, a Qualified
Public Stockholder whose relative stock interest in the Company is "minimal"
and who exercises no control over the affairs of the Company will be eligible
for capital gain treatment assuming that his percentage ownership in the
Company decreases as a result of the Recapitalization.     
   
  It is also possible that a public stockholder may satisfy other "safe harbor"
tests that establish whether a distribution does not have the effect of a
dividend and should be treated as a sale or exchange. Tax counsel to the
Company has not opined as to the character of any gain that a particular
stockholder may realize in the Recapitalization because of the inherently
factual nature of the determination that each such stockholder must make.
Public stockholders should consult their tax advisors as to whether any such
"safe harbor" test may be satisfied.     
 
  If an exchange has the effect of a dividend distribution to a public
stockholder, the gain to such stockholder will be treated as a dividend, which
is not in excess of each such stockholder's ratable share of the undistributed
earnings and profits of the Company. The remainder of any gain will be treated
as gain from the exchange of property. A corporate stockholder will generally
be entitled to the 70% dividends received deduction with respect to any such
dividend. However, under the rules for "extraordinary dividends," a corporate
stockholder may be required to reduce its basis in a New Share or share of
Public Preferred Stock immediately before any sale or disposition of such stock
under Section 1059 of the Internal Revenue Code. In general, such basis
reduction must occur if a corporate stockholder has not held its Old Share for
more than two years before the dividend announcement date and the amount of
such dividend equals or exceeds certain threshold percentages of the
stockholder's adjusted basis in the Old Share. Corporate stockholders should
consult their tax advisors with regard to the application and operation of
these rules.
   
  4.  A public stockholder's tax basis in the New Shares (and, if the Offerings
are not consummated, in the Public Preferred Stock (as represented by
Depositary Preferred Shares)) received in the Recapitalization will be equal to
the stockholder's tax basis in the Old Shares exchanged therefor in the
Recapitalization, increased by the amount of any gain recognized by the
stockholder and decreased by the amount of cash received if the Offerings are
consummated or, if the Offerings are not consummated, the sum of (i) the fair
market value of the Debentures and (ii) the amount of cash received. If the
Offerings are not consummated, the aggregate basis of the New Shares and Public
Preferred Stock (as represented by Depositary Preferred Shares) will be
allocated among the stock received in proportion to the relative fair market
values of the New Shares and Public Preferred Stock (as represented by
Depositary Preferred Shares) at the Effective Time. The holding period of such
New Shares (and, if the Offerings are not consummated, of the Public Preferred
Stock (as represented by Depositary Preferred Shares)) will include the holding
period of the Old Shares exchanged in the Recapitalization. Gain, loss and tax
basis (determined as described above) must be calculated separately for each
block of Old Shares (i.e., Old Shares acquired at the same time in a single
transaction) held by a public stockholder.     
   
  5.  If the Offerings are not consummated, holders of Old Shares who receive
Debentures in the Recapitalization will have a basis in such Debentures equal
to their fair market value as of the Effective Time.     
 
                                       58
<PAGE>
 
  6.  The excess of net long-term capital gains over net short-term capital
losses may be taxed at a lower rate than ordinary income for certain non-
corporate taxpayers. A capital gain is long-term if the asset is held for more
than one year and is short-term if the asset is held for one year or less. The
distinction between capital gain or loss and ordinary income or loss is also
relevant for purposes of, among other things, the limitation on the
deductibility of capital losses.
   
  7.  If the Offerings are not consummated, the Public Preferred Stock that is
received in the Recapitalization should not be classified as "Section 306
stock" because the holders of Public Preferred Stock (as represented by
Depositary Preferred Shares) should not avoid gain recognition by reason of
Section 305(a) of the Internal Revenue Code, the receipt of the Public
Preferred Stock (as represented by Depositary Preferred Shares) should not be
substantially the same as the receipt of a stock dividend, and the holders of
Public Preferred Stock (as represented by Depositary Preferred Shares) should
not have a basis in such stock which is determined by reference to the basis of
Section 306 stock. In addition, the requirements of Section 306(b)(4) of the
Internal Revenue Code may be satisfied by holders of Public Preferred Stock (as
represented by Depositary Preferred Shares). In general, Section 306(b)(4) is
satisfied if it is established that the distribution and disposition of Public
Preferred Stock (as represented by Depositary Preferred Shares) was not in
pursuance of a plan having as one of its principal purposes the avoidance of
Federal income tax. If the Public Preferred Stock (as represented by Depositary
Preferred Shares) were to be classified as "Section 306 stock" and Section
306(b)(4) were not satisfied, this would, in general, result in the amount
realized on a disposition of such stock (other than in a redemption) as being
treated as ordinary income to the extent that the amount realized were not in
excess of the amount that would have been a dividend if, instead of the stock,
the Company had distributed cash in an amount equal to the fair market value of
the stock. Therefore, such amount would be ordinary income up to the
stockholder's share of the amount of earnings and profits of the Company
available for distribution. If the amount realized were to exceed the amount
that would have been a dividend, the remainder would be treated as gain from
the sale of such stock to the extent that it exceeds the adjusted basis of the
stock.     
   
  8.  Stockholders who receive cash in lieu of fractional New Shares, Public
Preferred Stock (as represented by Depositary Preferred Shares) and/or
Debentures should be treated as having received the cash in redemption of the
fractional security interest. If the cash payment for the fractional security
interest exceeds the adjusted tax basis in the fractional security interest, a
stockholder should realize gain to the extent of the excess cash. If the cash
payment is less than the adjusted basis in the fractional security interest
exchanged, a stockholder should realize a loss. Such gain or loss should be
capital gain or loss, assuming that the Old Share is held as a capital asset by
the stockholder. Stockholders should consult their tax advisors regarding the
appropriate treatment of any cash that is received in exchange for fractional
security interests.     
   
  9.  Dividend and interest payments received by a United States Alien (as
defined below) may be subject to United States Federal withholding tax. A
United States Alien holder will not be subject to United States Federal income
or withholding tax on any gain realized on the taxable sale or exchange of the
New Shares, Public Preferred Stock (as represented by Depositary Preferred
Shares) or the Debentures unless either (a) the gain is derived from sources
within the United States and the United States Alien is an individual who was
present in the United States for 183 days or more during the taxable year or
(b) the stock sold or exchanged is a "United States Real Property Interest" as
defined in Section 897(c)(l) of the Internal Revenue Code at any time during
the five years prior to the sale or exchange of the stock or at any time during
the time that the United States Alien held such stock, whichever time is
shorter. The New Shares or the Public Preferred Stock (as represented by
Depositary Preferred Shares) will be a United States Real Property Interest
only if, at any time during the five years prior to the sale or exchange of
such stock or at any time during the period that the United States Alien held
such stock, whichever time is shorter, the Company is a "United States real
property holding corporation" as defined in Section 897(c)(2) of the Internal
Revenue Code and the United States Alien directly or constructively owned more
than 5% of that class of stock of the Company being sold or exchanged. The
Company is not a "United States real property holding corporation" for Federal
income tax purposes.     
 
 
                                       59
<PAGE>
 
  A "United States Alien" is any person who, for United States Federal income
tax purposes, is a foreign corporation, a nonresident alien individual, a
nonresident alien fiduciary or a foreign estate or trust, or a foreign
partnership that includes as a member any of the foregoing persons.
   
  10.  Certain non-corporate holders of the New Shares, Public Preferred Stock
(as represented by Depositary Preferred Shares) or Debentures may be subject to
backup withholding at a rate of 31% on payment of dividends or interest on such
securities, as the case may be. Backup withholding will apply only if (i) such
a holder fails to furnish its Taxpayer Identification Number ("TIN") which, for
an individual, would be his or her Social Security number, (ii) such a holder
furnishes an incorrect TIN, (iii) the payor is notified by the IRS that such
holder has failed to properly report payments of interest or dividends or (iv)
under certain circumstances, such holder fails to certify under penalties of
perjury that he or she has furnished a correct TIN and has not been notified by
the IRS that he or she is subject to backup withholding for failure to report
payments of interest or dividends. These backup withholding rules may also
apply to payments of cash and Debentures by the Exchange Agent (as defined
below) in the Recapitalization (including cash in lieu of a fractional
securities interest). Stockholders should consult their tax advisors regarding
their qualification for exemption from backup withholding and the procedures
for obtaining such an exemption if applicable.     
   
  The amount of any backup withholding from a payment to a holder of the New
Shares, Public Preferred Stock (as represented by Depositary Preferred Shares)
or Debentures will be allowed as a credit against such security holder's
Federal income tax liability and may entitle such security holder to a refund,
provided that the required information is furnished to the IRS.     
 
  11.  The Recapitalization will result in an "ownership change" within the
meaning of Federal income tax law provisions dealing with net operating loss
carryforwards, alternative minimum tax credits and other similar tax
attributes. Thus, as a technical matter there will be limitations on the
Company's ability to utilize such carryforwards and credits from periods
predating the Recapitalization. However, as a practical matter, application of
those limitations to the Company is not expected to impair the Company's
ability to use its tax attributes.
 
  THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE ARE FOR GENERAL
INFORMATION ONLY. EACH STOCKHOLDER SHOULD CONSULT A TAX ADVISOR AS TO THE
PARTICULAR CONSEQUENCES OF THE RECAPITALIZATION THAT MAY BE APPLICABLE TO SUCH
STOCKHOLDER, INCLUDING THE APPLICATION OF STATE, LOCAL, AND FOREIGN TAX LAWS.
 
                                   LITIGATION
 
  Two actions are pending in the Court of Chancery of the State of Delaware in
and for New Castle County with respect to the Recapitalization. Both actions
are brought as class actions, purportedly on behalf of a class consisting of
all stockholders of UAL Corporation.
 
  The first action, Kaufman et al. v. Wolf et al., Civil Action No. 13312, was
commenced by three stockholders of the Company on or about December 30, 1993.
Named as defendants, in additional to the Company, ALPA and the IAM, were
Stephen M. Wolf, John C. Pope, Neil A. Armstrong, Andrew F. Brimmer, Richard P.
Cooley, E. Mandell de Windt, John F. McGillicuddy, Harry Mullikin, James J.
O'Connor, Frank A. Olson and Ralph Strangis. The Kaufman complaint alleges,
among other things, that defendants have violated their fiduciary duties to the
Company stockholders in connection with the proposed transaction between the
Company, ALPA and the IAM. The complaint seeks, among other things, an
injunction against the consummation of the Agreement in Principle, an order
rescinding the transaction if it has been consummated and an award of
unspecified damages in favor of plaintiffs and the class.
 
  The second action, Krasner v. UAL Corp. et al., Civil Action No. 13316, was
commenced by a stockholder of the Company on or about January 6, 1994. Named as
defendants in addition to the Company,
 
                                       60
<PAGE>
 
ALPA and the IAM, were Stephen M. Wolf, John C. Pope, Neil A. Armstrong, Andrew
F. Brimmer, Richard P. Cooley, Carla A. Hills, Fujio Matsuda, John F.
McGillicuddy, Harry Mullikin, James J. O'Connor, Frank A. Olson, Ralph Strangis
and Paul E. Tierney, Jr. The Krasner complaint alleges, among other things,
that defendants have violated their fiduciary duties in connection with the
proposed transaction. It seeks a declaratory judgment that the individual
defendants have breached their fiduciary duties to the class, an injunction
against the consummation of the transaction and against "the enforcement of any
anti-takeover device," an order requiring the individual defendants to
"explor[e] third-party interest" in acquiring the Company and to "accept [ ]
the highest offer obtainable for the public shareholders or permit [ ] the
shareholders to make that decision free from any coercion" and an award of
unspecified damages in favor of plaintiff and the class.
 
  Both the Kaufman action and the Krasner action are at a preliminary stage.
Defendants have not responded to the complaint in either action, no discovery
has been taken and plaintiffs have not yet moved for class certification.
 
                          THE PLAN OF RECAPITALIZATION
   
  The information contained in this Proxy Statement/Prospectus with respect to
the Plan of Recapitalization is qualified in its entirety by reference to the
complete text of the Plan of Recapitalization, a copy of which is included
elsewhere in this Proxy Statement/Prospectus.     
 
INVESTMENT FOR UNIONIZED EMPLOYEES
 
 Wage and Benefit Adjustments
 
  Employees represented by ALPA and the IAM will receive reductions of 15.7
percent and 9.7 percent, respectively, from basic wage rates in effect at the
Effective Time. A 5 percent increase previously scheduled to take effect for
IAM-represented employees on May 1, 1994 will be eliminated. ALPA employees
participating in U2 will be subject to further wage reductions as described
below. However, the normal increases for seniority steps and promotions will be
maintained.
 
  The reduced wage rates will remain in effect for five years, nine months
following the Effective Time for ALPA, and six years for the IAM, except that
during the fourth and fifth years following the Effective Time each employee
group may receive a wage increase. If the parties are unable to negotiate the
amount of such an increase, a neutral arbitrator will determine the amount, if
any (and not to exceed 5 percent each year), based upon airline industry
trends, profitability of the Company and wage rates for other specified major
air carriers. In addition, the neutral arbitrator may determine the amount of
increase in the ALPA per diem, if any (not to exceed $.25), based upon the same
factors.
 
  Upon the Effective Time, the Company contribution to the self-directed
retirement plan provided for each ALPA-represented pilot will be reduced from 9
percent of wages to 1 percent of wages. In addition, the vacation accrual
schedule for pilots during their first ten years of employment will be reduced
to the vacation accrual schedule for pilots employed by Southwest. For IAM-
represented employees, the current half-hour paid lunch period will be
eliminated and the standard work day increased to eight hours exclusive of the
unpaid lunch period. In addition, the premium for a paid lunch on overtime also
will be eliminated.
       
  All wage and benefit reductions will remain in effect pursuant to the Railway
Labor Act until the effective date of the revised collective bargaining
agreements negotiated and/or arbitrated pursuant to procedures stated in the
Plan of Recapitalization and described in this Proxy Statement/Prospectus.
 
 AFA Participation
   
  If AFA and the Company determine that AFA will participate in the
Recapitalization, flight attendants will incur a combination of wage
reductions, benefit changes and work-rule modifications negotiated between     
 
                                       61
<PAGE>
 
management and AFA, and determined by management in its sole judgment to equal
$416 million net present value, including an appropriate agreed upon
contribution associated with the competitive action plan contemplated with
respect to U2 by the Plan of Recapitalization (the "Competitive Action Plan").
If AFA participates on this basis, the duration of wage and benefit reductions
(other than the contribution in respect of the Competitive Action Plan)
applicable to the other employee groups will be reduced by nine months.
 
 Competitive Action Plan
 
  In addition to wage and benefit reductions affecting all employees, ALPA and
IAM have agreed to permit the Company to establish a Competitive Action Plan
pursuant to which United would establish an "airline-within-an-airline"
currently referred to as "U2," which is designed to compete with existing low-
cost carriers in short-haul markets. The Unions will represent U2 employees in
the same class and craft, and United and U2 will have the same seniority lists
and will remain a single carrier for Federal Aviation Act and Railway Labor
Act purposes. The Company, at its discretion, may establish a distinct U2
corporate division but does not currently plan to establish U2 as a separate
subsidiary of either United or the Company.
 
  The pilot wages and work-rules for the U2 operation are contained in
amendments to the ALPA collective bargaining agreement. These work-rule
changes are designed to facilitate a high-frequency, rapid turn-around,
streamlined service operation. Pursuant to those changes in the ALPA
collective bargaining agreement, ALPA-represented pilots in the U2 operation
would receive wage rates approximately 7.1 percent less than the reduced
mainline United rates for similar equipment in the United operation. Pilots
assigned to the U2 operation will also be expected to fly more hours each
month. As a result, pilot staffing requirements in the U2 operation are
expected to be reduced and U2 pilots should have the opportunity to achieve
monthly pay equivalent to comparable mainline United pilots by flying more
hours each month. The U2 operation would be subject to modified work-rules
designed for the U2 operation. The U2 supplement would have an initial term
equivalent to the basic agreement; it would also provide, however, for two
renewal periods following the initial term, for a total of 12 years following
the Effective Time. With respect to the two renewal periods, certain
unresolved economic issues would be submitted to interest arbitration. In such
interest arbitrations, the arbitrator would be required to establish the
renewal terms on the basis of wages and work-rules then in effect at Southwest
or such other short-haul carrier as then operates the largest number of B737
or equivalent aircraft other than American, Delta Air Lines, Continental
Airlines, Northwest Airlines and USAir. ALPA-represented employees would be
barred from striking over the U2 employment terms determined through interest
arbitration under this process.
 
  U2 would be permitted to operate on any non-stop city pair of 750 nautical
miles or less in the contiguous 48 states, using B737-300 or smaller aircraft,
subject to the following restrictions: (a) U2 could not operate between United
hub cities and/or international gateway cities except the Los Angeles basin
and the San Francisco Bay area service, (b) U2 block hours could not exceed 20
percent of United's systemwide block hours up to 2 million block hours per
year, and 25 percent of the systemwide block hours thereafter, provided that
in the sixth through twelfth years following closing, U2 could begin operation
between any city pairs not serviced by United during the prior 24 months, (c)
if system widebody block hours (i.e., block hours flown by B757 or larger
aircraft) fall below (i) 95% of the widebody block hours projected in the
Company's October 1993 fleet plan for any twelve month period from the
Effective Time through 1999 or (ii) a certain minimum level for any twelve
month period between 2000 and 2006, U2 operations must be reduced by the
amount of such shortfall and (d) 10 percent of U2 monthly block hours must be
between city pairs not served by United within the prior 24 months.
 
  To permit rapid implementation of U2, the Competitive Action Plan provides
that United pilots can be involuntarily placed into the U2 operation, but such
employees must be "red-circled" to maintain the monthly income they would have
earned had they remained in their existing positions in the mainline United
operation. United pilots who voluntarily bid into or remain in the U2
operations, and new hires, will not be red-circled.
 
 
                                      62
<PAGE>
 
  IAM-represented employees assigned to the U2 operation will be governed by
the same revised Collective Bargaining Agreements as all other IAM-represented
employees. The IAM agreements, governing all IAM-represented employees, contain
certain specific modifications that can not be amended for 12 years. These
include (a) elimination of the paid half-hour lunch period and increasing hours
of service to eight hours exclusive of the unpaid lunch and elimination of a
paid meal period on overtime, (b) a provision that the Company will assign IAM
ramp servicemen at any U.S. station that has a sustained flight level of 40 or
more daily departures for a period of six months (and may discontinue such
assignments if the flight activity falls below 30 daily departures on a
sustained level) and may assign no more than 25 percent of such positions to
part-time ramp servicemen and (c) a provision, subject to certain restrictions,
that the Company may contract out up to 20 percent of its maintenance work,
determined annually on a dollar value basis, subject to the condition that
subcontracting will not cause a layoff.
 
 Job Security Provisions
 
  The ALPA collective bargaining agreement will be amended to add a new section
that would supersede and supplement several existing job security provisions.
The principal terms of this new section are as follows:
 
    (i) All commercial flight operations conducted by United, the Company or
  any corporate affiliate must be performed by United pilots under the terms
  of the United-ALPA agreement, except for (a) feeder flying conducted by
  United Express or similar carriers operating small aircraft, (b) certain
  domestic code sharing currently in effect and additional domestic code
  sharing not to exceed 1 percent of the Company's total domestic block hours
  and (c) international code sharing arrangements with foreign carriers so
  long as the arrangements do not cause a reduction in international flying
  and the Company does not expand international code sharing once it reduces
  international flying below a specified minimum level;
 
    (ii) United may not transfer aircraft or international routes to other
  carriers that will use the assets to provide feed to United pursuant to an
  agreement with United;
 
    (iii) United may not enter into any successorship transaction unless the
  successor agrees to adopt the United-ALPA agreement, to employ United
  pilots pursuant to such agreement, to recognize ALPA and to provide United
  pilots with seniority credit if the successor is an air carrier;
 
    (iv) The Company will continue in effect, or amend to include, certain
  provisions of a Letter of Agreement that (a) provide ALPA with enumerated
  rights in the event of a change of control of the Company, (b) prohibit
  furloughs, within certain conditions, if the Company disposes of 25 percent
  or more of its assets or assets which produce 25 percent or more of its
  block hours and (c) obligate the Company to require any carrier purchasing
  aircraft or route authority that produce 25 percent or more of the
  Company's operating revenues or block hours to hire an appropriate number
  of United pilots with seniority credit;
 
    (v) With certain exceptions, the Company may not sell or otherwise
  dispose of its Denver training center or contract with any person or entity
  to conduct or supervise United pilot training;
 
    (vi) The Company may not establish a pilot domicile outside of the United
  States without ALPA's consent, except for temporary domiciles permitted
  under the existing agreement; and
 
    (vii) Subject to specified exceptions, no pilot employed as of the date
  of closing may be furloughed while the agreement remains in effect.
 
  The IAM collective bargaining agreements will be amended to provide a number
of job security provisions as well. The principal terms of these amendments are
as follows:
 
    (i) Subject to certain exceptions, no IAM represented employee employed
  as of the date of the Effective Time may be furloughed during the term of
  the agreement;
 
    (ii) Subject to certain conditions, the Company may not contract out work
  if the subcontract would result in the layoff of any IAM-represented
  employee;
 
                                       63
<PAGE>
 
    (iii) The Company may not contract out ramp service work at any station
  at which it currently employs IAM-represented ramp servicemen;
 
    (iv) Subject to certain exceptions, the Company may not sell or otherwise
  dispose of its maintenance facilities in San Francisco, Oakland or
  Indianapolis, its Miami flight kitchen or its four employee cafeterias;
 
    (v) The Company may not perform any regularly scheduled heavy maintenance
  outside the United States without IAM approval;
 
    (vi) The Company will transfer dispatch work currently performed in
  London to Chicago-based, IAM-represented dispatchers;
 
    (vii) The IAM agreements will contain change of control provisions,
  successorship and code sharing restrictions similar to those provided to
  ALPA; and
 
    (viii) At least 80% of maintenance work must be performed by United and
  not be outsourced.
 
 No Strike Clauses
   
  The ALPA and IAM revised Collective Bargaining Agreements will contain no
strike clauses, including a prohibition on sympathy strikes in support of other
unions, to be effective until the amendable dates of such agreements.     
 
 Other Collective Bargaining Agreement Modifications
 
  Both the ALPA and IAM revised Collective Bargaining Agreements will be
subject to additional amendments, which do not have any material financial
effect, of a type made in the ordinary course of collective bargaining
negotiations.
 
  IAM-represented employees who lose, or have lost, employment with United as a
result of the sale of United flight kitchens to Dobbs and Caterair will receive
labor protective provisions benefits modeled after the Allegheny-Mohawk Labor
Protective Provisions previously utilized by the Civil Aeronautics Board.
 
INVESTMENT FOR SALARIED AND MANAGEMENT EMPLOYEES
 
  United will establish employment terms for the employees of United who
perform the functions currently performed by the management and salaried
employees of United (including any functions that such group of employees begin
performing in the future). The basic cost reduction package for United's U.S.
based Salaried and Management Employees will be in effect for a period of five
years, nine months following the Effective Time, except as noted below. The
components of the basic cost reduction package include pay reductions (base pay
reduced 8.25%, shift differentials redefined, overtime paid lunch eliminated,
four fixed holidays converted to floating holidays for operational employees),
changes in work-rules, sick leave policy and management relocation policy and a
one-time reduction in force of 127 management employees.
   
  The Company's United States Salaried and Management Employees may receive an
appropriate wage rate increase of not more than 5% beginning in the fourth year
(and, if applicable, the fifth year) following the Effective Time through a
program determined by management whose criteria are consistent with certain
specified standards that take into account (i) airline industry trends, (ii)
United's financial performance (including cumulative profitability over the
prior three years) and (iii) the wage rate levels for comparable employees of
American, Delta, USAir and Northwest Airlines.     
 
  Salaried employees hired February 1, 1994 and later will be hired in
accordance with a new hire pay and benefit compensation program. In addition,
no wage increase or wage raises, other than increases for legitimate promotions
from one job group to another job group, progression type increases and
increases resulting from the wage adjustment process outlined above, may be
given to Salaried and Management Employees during the basic investment period.
 
                                       64
<PAGE>
 
  Salaried and management per capita base payroll may not increase by more than
the percentage increase in the IAM per capita base payroll in any investment
year (excluding increases resulting from the mid-term wage adjustment process
for IAM-represented employees) or by 2% in any investment year (except 1.5% in
the fourth and fifth investment years), whichever is less. For the purposes of
the foregoing limitation, increases resulting from the wage adjustment process
outlined above may not be included.
   
  United will modify its United States personnel policies to provide that it is
United's intention to conduct its business so that any salaried employee whose
date of employment is before February 1, 1994 and who is affected when United
declares a surplus in his or her organization will not be laid off
involuntarily, and the Company will make every reasonable effort to offer
surplus employees an opportunity of continued employment in his or her current
work status (i.e., full- or part-time), although it may be in a different
classification and/or location within the United States. Surplus employees who
must relocate in order to continue employment will be eligible for relocation
assistance. These provisions do not apply in the case of an employee who is
discharged for cause or violation of Company rules, codes or articles of
conduct or in the case of surpluses that result from an act of nature, a labor
dispute, government action, revocation of operating certificate, war,
unavailability of fuel or other circumstances beyond the control of the
Company. These provisions also do not apply to discharges of employees who are
in a probationary period and, unless amended, will not be in effect beyond the
five year, nine month period (a five year period if the AFA participates)
following the Effective Time.     
 
  See "SPECIAL FACTORS--Certain Risk Factors--Possible Effect of Organization
of Additional Employees" with respect to the possible impact of organization of
management and salaried employees.
   
REVISED GOVERNANCE STRUCTURE     
 
  The information contained in this Proxy Statement/Prospectus with respect to
the revised governance structure of the Company is qualified in its entirety by
reference to the complete text of the Restated Certificate, a copy of which has
been filed as an exhibit to the Registration Statement of which this Proxy
Statement/Prospectus is a part and which is incorporated herein by reference,
and to the other agreements and documents referred to herein that are filed as
exhibits to the Registration Statement of which this Proxy Statement/Prospectus
is a part.
 
 Composition of the Board
   
  Following the consummation of the Recapitalization, subject to the rights of
holders of Series A Preferred Stock and the Depository Preferred Shares
representing interests in Public Preferred Stock to elect a total of two
additional directors in the event of certain dividend arrearages (the
"Preferred Stock Dividend Default Rights") and prior to the Sunset, the Board
will consist of 12 directors, who will include (i) five Public Directors, (ii)
four Independent Directors, (iii) two Union Directors and (iv) one Salaried and
Management Director (the Union Directors and the Salaried and Management
Director, collectively, are referred to as the "Employee Directors"). For
information relating to the initial nominees for election as Public Directors
and certain other persons chosen to serve as the other directors if the
Recapitalization is consummated, see "ELECTION OF DIRECTORS." Following the
Sunset, subject to the Preferred Stock Dividend Default Rights and the
occurrence of either or both of the ALPA Termination Date and the IAM
Termination Date (both as defined below, see "--Sunset"), the Board will
consist of 12 directors of whom nine will be elected by the holders of the New
Shares and three will be Employee Directors.     
       
 Public Directors
 
  Until the Sunset, five directors, who are designated as Public Directors (the
"Public Directors") will be elected by holders of the New Shares and will
consist of (a) three individuals who are not and have never been an officer or
employee of, or a provider of professional services to, the Company or any of
its subsidiaries
 
                                       65
<PAGE>
 
(the "Outside Public Directors") and (b) two substantially full-time employees
of the Company or any of its subsidiaries, one of whom, in addition, to the
fullest extent such additional qualification is permitted by law, will be, at
the time of election, the CEO, and the other of whom, in addition, to the
fullest extent such additional qualification is permitted by law, will be a
senior executive officer of the Company satisfactory to the CEO (the
"Management Public Directors"). Until the Sunset, at the expiration of the term
of each Outside Public Director and to fill vacancies, Outside Public Directors
will be nominated or appointed, as appropriate, by an "Outside Public Director
Nomination Committee" comprised of the Outside Public Directors. Any amendment
or modification of the rights, powers, privileges or qualifications of the
Outside Public Directors or the Outside Public Director Nomination Committee
will, in addition to the approval required by law or as described below under
the Restated Certificate, require the concurrence of all of the Outside Public
Directors or the affirmative vote of at least a majority in voting power of the
outstanding capital stock of the Company entitled to vote thereon excluding
shares held by the ESOP Trustee. In addition, until the Sunset, Management
Public Directors will be nominated or appointed, as appropriate, by a majority
vote of the entire Board.
 
  Mr. John F. McGillicuddy, Mr. James J. O'Connor and Mr. Paul E. Tierney, Jr.,
who are incumbent members of the Board, have been nominated to be the Outside
Public Directors, and Mr. Gerald M. Greenwald has been nominated to be the
Management Public Director. The second Management Public Director will be
identified prior to or at the Effective Time and will be appointed to the Board
at the Effective Time. For additional information on these individuals, see
"ELECTION OF DIRECTORS--Nominees for Election as Public Directors."
 
 Independent Directors
   
  The four directors designated as Independent Directors (the "Independent
Directors") will be elected by the holders of Class I Preferred Stock (as
defined below, see "DESCRIPTION OF SECURITIES--The Director Preferred Stock--
Class I Preferred Stock"), who will be the Independent Directors. Each
Independent Director, upon becoming an Independent Director, acquires a share
of Class I Preferred Stock and becomes a party to the Class I Preferred
Stockholders' Agreement pursuant to which the stockholders will agree to vote
their shares to elect the Independent Directors nominated in accordance with
the procedures set forth below and to refrain from transferring their shares of
Class I Preferred Stock other than to a person who has been elected to serve as
an Independent Director and who agrees to be subject to the provisions of the
Class I Preferred Stockholders' Agreement.     
 
  None of the Independent Directors may have, without the consent of both Union
Directors and all of the Public Directors, a current or prior material
affiliation or business relationship with the Company (other than an
affiliation that results from being a member of the Board) or be an officer,
director, trustee or official of any labor organization that serves as a
collective bargaining "representative" under the Railway Labor Act or the
National Labor Relations Act. In addition, generally, at least two of the four
Independent Directors at the time of their initial nomination or appointment to
the Board must (i) be a senior executive officer of a private or public company
with revenues in excess of $1 billion during such company's prior fiscal year
and/or (ii) be a member of the board of directors of at least one other public
company with a market capitalization in excess of $1 billion as of the date of
such company's most recent annual financial statements.
 
  The Independent Directors will be nominated or appointed, as appropriate, by
an "Independent Director Nomination Committee" consisting of the Independent
Directors and the Employee Directors. Approval of such nomination or
appointment requires a majority of the Independent Directors and the
concurrence of at least one Union Director.
   
  ALPA and the IAM have identified Mr. Duane D. Fitzgerald, Mr. Richard D.
McCormick, Mr. John K. Van de Kamp and Mr. Paul A. Volcker as the initial
Independent Directors and such identified persons have agreed to serve as the
Independent Directors. For additional information on these individuals, see
"ELECTION OF DIRECTORS--Independent Directors."     
 
                                       66
<PAGE>
 
 Employee Directors
   
  The three Employee Directors will be elected as follows: (i) one director
(the "ALPA Director") will be elected by the holder of the Class Pilot MEC
Preferred Stock (as defined below, see "DESCRIPTION OF SECURITIES--The Director
Preferred Stock"), which will be the ALPA-MEC, (ii) one director (the "IAM
Director" and, together with the ALPA Director, the "Union Directors") will be
elected by the holder of the Class IAM Preferred Stock (as defined below, see
"DESCRIPTION OF SECURITIES--The Director Preferred Stock"), which will be the
IAM or its designee, and (iii) one director (the "Salaried and Management
Director") will be elected by the holders of the Class SAM Preferred Stock (as
defined below, see "DESCRIPTION OF SECURITIES--The Director Preferred Stock"),
who will be the Salaried and Management Director and an additional designated
stockholder (the "SAM Designated Stockholder"), each selected as described
below, voting separately as a class.     
   
  The replacement Salaried and Management Director will be nominated by the
System Roundtable. The System Roundtable will establish a selection committee
of four employees to select the nominee for Salaried and Management Employee
Director from time to time. The SAM Designated Stockholder generally will be
the senior executive of United who has primary responsibility for human
resources. The Salaried and Management Director will acquire two shares of
Class SAM Preferred Stock, and the SAM Designated Stockholder will acquire one
share of Class SAM Preferred Stock upon becoming the Salaried and Management
Director and the SAM Designated Stockholder, respectively, and each will become
a party to the Class SAM Preferred Stockholders' Agreement pursuant to which
the stockholders will agree to vote their shares to elect the Salaried and
Management Director nominated by the System Roundtable and to refrain from
transferring the shares of Class SAM Preferred Stock other than to a person who
has been elected to serve as the Salaried and Management Director or to the
senior executive of United who has primary responsibility for human resources
and, in each case, who agrees to be subject to the provisions of the Class SAM
Preferred Stockholders' Agreement. The "System Roundtable" is a body of
Salaried and Management Employees empaneled to review and discuss issues
relating to the Company and their effect on Salaried and Management Employees.
    
  Vacancies of Employee Directors may be filled only by the holder or holders
of the class of stock that elected such director.
   
  Mr. John Peterpaul has been identified as the initial IAM Director, Captain
Roger D. Hall has been identified as the initial ALPA Director, and Mr. Joseph
V. Vittoria has been identified as the initial Salaried and Management
Director. For additional information on Mr. Peterpaul, Captain Hall and Mr.
Vittoria, see "ELECTION OF DIRECTORS--IAM Director", "--ALPA Director" and "--
Salaried and Management Director."     
       
       
 Quorum
   
  Until the Sunset, a quorum at a Board meeting will exist only if (a)
directors with at least a majority of the votes entitled to be cast by the
entire Board are present (i.e., seven votes) and (b) unless consented to by the
two Union Directors, if less than all votes are present, the number of votes
constituting a majority of the votes present is no greater than the sum of (i)
two plus (ii) the number of Independent Director votes present at the meeting.
For example, if three Independent Director votes are present, the total number
of Director votes present may not be more than nine in order for a quorum to be
present. The foregoing quorum provisions were requested by the Unions and
agreed to by the Company in connection with negotiating the terms of the
Recapitalization.     
 
 Required Board Action
   
  Except as may be required by law or as set forth in the Restated Certificate
(including the matters described below under "--Extraordinary Matters" or "--
Special Voting Provisions with Respect to Purchase and Sale of Common Stock"),
approval of all Board action will require a majority vote of the total number
of     
 
                                       67
<PAGE>
 
director votes present at a meeting at which a quorum is present. Until the
Sunset, in the event of a vacancy of an Independent Directorship, the remaining
Independent Directors will as a group continue to have four votes (divided
equally among the remaining Independent Directors). Until the Sunset, in the
event of a vacancy on the Board of an Employee Directorship or a Public
Directorship, or in the event of a vacancy of an Independent Directorship that
immediately prior to the occurrence of such vacancy was held by a member of a
Board Committee of which only one Independent Director was a member, then,
subject to the fiduciary duties of the remaining Directors or members of such
Board Committee, as the case may be, then in office, neither the Board nor such
Board Committee may take any action (other than to fill such vacancy) until
after the earlier of (i) 20 days following the occurrence of such vacancy and
(ii) the time that such vacancy is filled in accordance with the Restated
Certificate.
 
 Term of Office; Resignation; Removal
 
  Each Director will hold office until the next annual meeting of stockholders
and until his or her successor is elected and qualified, subject to such
Director's earlier death, resignation or removal. In addition, the term of an
Outside Public Director or an Independent Director will automatically terminate
if such Director ceases to meet the qualifications of an Outside Public
Director or Independent Director, as the case may be. Any Director may resign
at any time upon written notice to the Company. Directors may not be removed
from office except (i) without cause, by the class of stockholders that elected
them, or (ii) "for cause" as determined under the DGCL.
 
 Selection of Management
 
  All decisions to hire or fire members of senior management will be taken by
the Board or pursuant to the authority typically delegated by it to the CEO.
Until the Sunset, hiring a new CEO will require the approval of a majority of
the Board following a recommendation by the Executive Committee, which will act
as the search committee. If, at the first meeting of stockholders following the
hiring of a new CEO (other than the initial CEO following the Effective Time),
such CEO is not elected to the Board as a Public Director by the stockholders
entitled to vote on such election, such CEO will be removed from office and a
successor CEO will be selected. Any successor CEO will be appointed to fill the
Public Directorship vacated by the predecessor CEO. Incumbent officers at the
Effective Time may not be terminated for a period of six months following the
Effective Time unless such termination is approved by two Outside Public
Directors and the CEO. As part of the Recapitalization, certain officers have
agreed to retire at or prior to the Effective Time. See "SPECIAL FACTORS--
Interests of Certain Persons in the Recapitalization."
 
 Stockholder Approval Matters
 
  Stockholder approval will not be a condition to any action of the Company
except as required by DGCL or as described below under "--Extraordinary
Matters" or "--Special Voting Provisions with Respect to Purchase and Sale of
Common Stock". Until the Sunset, except as otherwise required by law or by the
Restated Certificate, the presence in person or by proxy of the holders of
outstanding shares representing at least a majority of the total voting power
of all outstanding shares entitled to vote at a meeting of stockholders will
constitute a quorum at a meeting of stockholders.
 
 ESOP Voting
   
  Allocated shares of Voting Preferred Stock (and, under any limited
circumstances required by law in which matters are submitted to it for a vote,
the ESOP Preferred Stock) held by the Qualified ESOP (as defined in "--
Establishment of ESOPs--Sales of ESOP Preferred Stock--Leveraged ESOP") will be
voted by participants, as named fiduciaries under ERISA, on a confidential pass
through basis. ALPA and the Company agreed that ALPA may, by a request that
must be made no later than April 22, 1994, require that the Company amend the
Qualified ESOP to provide that only participants who are employees are entitled
to instruct the ESOP Trustee as to how to vote allocated shares of Class P
Voting Preferred Stock, including     
 
                                       68
<PAGE>
 
   
any such shares allocated to former employees. ALPA has made such a request.
However, the Company is not required to amend the Qualified ESOP in the
requested manner if it is determined that such an amendment would not be
legally permissible or would expose the Company to a risk of material
liability. In that event, then the Company would be obligated to cooperate with
ALPA to attempt to limit the ability to instruct the ESOP Trustee as to voting
of Class P Voting Preferred Stock to employees by other means. Unallocated
shares and allocated shares which were not voted by the participants in the
Qualified ESOP will be voted as described below by those ESOP participants who
are employees who choose so to direct State Street. State Street will (except
as may be required by law) vote the unallocated and otherwise unvoted shares in
the proportions directed by participants who give instructions to State Street
with respect to such shares; each participant who is an employee has the right
to give such directions to State Street in the proportion that the
participant's allocated shares bears to the allocated shares of all
participants giving such directions. Shares held by the Supplemental ESOP (as
defined in "--Establishment of ESOP--Sales of ESOP Preferred Stock--Non-
Qualified ESOP") will be voted as instructed by the administrative committee
appointed under the Supplemental ESOP. The Supplemental ESOP provides that the
administrative committee shall consider the sentiments of participants
concerning the vote, but is not required to take any particular action in
response thereto. The Supplemental ESOP provides that it shall be amended at
the request of ALPA to provide for pass-through voting by participants. See "--
Establishment of ESOPs". The foregoing provisions also govern instructions to
be given to State Street in the event of a tender offer (including a Control
Transaction, see "--Establishment of ESOPs--Control Transaction").     
 
 Extraordinary Matters
   
  Except as provided below, certain matters described below ("Extraordinary
Matters") generally will require, in addition to any voting requirements under
the DGCL, approval of at least either three-quarters of the Board (including
the concurrence of one Union Director) or three-quarters of the shares present
and voting at a stockholder meeting at which a quorum is present. In addition,
the vote of at least 66 2/3% of the outstanding voting stock that is not owned
by an "interested stockholder" will be required to approve a "business
combination" under Section 203 of the DGCL, where applicable. Extraordinary
Matters include:     
     
    (a) Amendments to the Restated Certificate (other than certain technical
  amendments), substantive amendments to the Bylaws and mergers or
  consolidations of the Company or any of its subsidiaries or a sale, lease
  or exchange of all or substantially all of the assets of the Company or
  United involving a person that has been formed by or is an affiliate of one
  or more labor groups representing employees of the Company or any of its
  subsidiaries or a person determined by the Board to be a person in which a
  substantial group of employees of the Company or any of its subsidiaries,
  acting as an organized group, owns a majority ownership interest (a "Labor
  Affiliate") (the Extraordinary Matters described in this paragraph (a)
  require, in addition to the approvals described above, either (i) six
  affirmative votes cast by Directors who are not Employee Directors or (ii)
  the affirmative vote of a majority of the shares of capital stock not held
  by ESOPs);     
 
    (b) Mergers or consolidations of the Company or any of its subsidiaries
  or a sale, lease or exchange of all or substantially all of the assets of
  the Company or United involving a person who is not a Labor Affiliate;
 
    (c) Dissolutions;
     
    (d) Entry into any new line of business outside the "airline business"
  (defined generally as the business of operating a domestic air carrier,
  together with any business or activities reasonably related to or in
  support of all of such operations engaged in by the Company or any
  subsidiary at or immediately prior to the Effective Time), or the making of
  any investment (in excess of five percent of the total assets of the
  Company and its subsidiaries on a consolidated basis) outside the airline
  business;     
 
    (e) The making of any domestic airline acquisition or any material
  investment in another airline including ordinary course investments in
  excess of one half of one percent of the total assets of the Company and
  its subsidiaries on a consolidated basis;
 
                                       69
<PAGE>
 
     
    (f) The adoption of any material amendment to the Rights Agreement (as
  defined below, see "--Rights Plan") or taking of any material actions,
  including the redemption of rights, under the Rights Agreement;     
     
    (g) The sale, lease, exchange, surrender to or at the direction of a
  lessor, or other disposition (a "Disposition") by the Company or any of its
  Subsidiaries of assets for "Gross Proceeds" (defined to exclude taxes and
  sales costs) that, when added to the Gross Proceeds from (i) the
  Disposition of other such assets during the preceding 365 day period
  resulting in Gross Proceeds in excess of $5 million and (ii) the
  Disposition of other such assets during a recently completed preceding
  twelve calendar month period resulting in Gross Proceeds of $5 million or
  less, collectively exceeds $200 million; provided that (A) Gross Proceeds
  included in clauses (i) and (ii) will not include Gross Proceeds from any
  transactions consummated prior to the Effective Time and (B) the $5 million
  set forth in clauses (i) and (ii) may be increased by action of the Board
  on an annual basis based on the affirmative vote of at least 75% of the
  votes entitled to be cast by the entire Board, which must include the
  concurrence of at least one Union Director; provided, further, that such
  approval will not be required for certain specified transactions (or count
  against the $200 million Gross Proceeds calculation above) including: (1)
  secured aircraft financings, (2) sale-leaseback and leveraged lease
  transactions, or sales or similar transfers of receivables, for financing
  purposes, (3) Dispositions of assets if replacement assets (consisting of
  assets of the same class as the assets being disposed of) generally have
  been ordered or acquired within the six calendar month period prior to such
  Dispositions of assets or so ordered or acquired within 365 days following
  the Disposition of assets for which no replacement assets had been
  previously acquired, (4) Dispositions providing Gross Proceeds in an amount
  up to 10% of the book value (net of depreciation) of the Company's fixed
  assets at the time of the most recent quarterly financial statements of the
  Company if (A) Directors entitled to cast at least 75% of the votes
  entitled to be cast by the entire Board, including all of the Independent
  Directors, determine by resolution of the Board that such asset Disposition
  is necessary to (I) cure a default under material financing agreements
  binding upon the Company or any of its subsidiaries or any of their
  respective properties, or avoid a default thereunder that, absent such
  Disposition, would be reasonably likely to occur within 90 days or (II)
  remedy a material adverse development in the Company's business or
  condition, and (B) the Gross Proceeds of such asset Disposition are used to
  remedy the condition referred to in clause (A) (provided, that the
  exception afforded by this clause (4) will be available not more than once
  in any consecutive five-year period), (5) certain ordinary course
  Dispositions designed to allow the Company and its subsidiaries to continue
  many of their existing practices without significant restrictions that may
  involve Dispositions of assets, (6) Dispositions of assets (other than air
  frames, engines and related spare parts) if (A) made pursuant to a discrete
  asset management program that provides for the Disposition of not more than
  an aggregate of $25 million of assets and (B) such discrete asset
  management program is approved annually by either the Board or the
  stockholders as an Extraordinary Matter in accordance with the voting
  thresholds outlined above and (7) Dispositions of assets that individually,
  or when aggregated with other assets in the same or related Dispositions,
  are not in excess of a de minimis amount, either with respect to periods
  prior to December 31, 1994 or pursuant to a distinct asset management
  program approved in accordance with the procedures set forth in clause (6)
  above; and     
     
    (h) The issuance of equity or equity equivalent securities (including
  convertible debt, but excluding non-voting, non-convertible preferred stock
  the issuance of which will be permitted without limit) (a "Non-Dilutive
  Issuance"); provided that such issuance shall not constitute an
  Extraordinary Matter if any of the following occur: (A) (I) three quarters
  of the votes entitled to be cast by the entire Board, including all the
  Independent Directors, determine that such issuance is in the best
  interests of the Company, (II) such issuance is subject to the First
  Refusal Agreement (as defined below, see "DESCRIPTION OF SECURITIES--The
  Common Stock, the Series A Preferred Stock and the Junior Participating
  Preferred Stock--Common Stock--Right of First Refusal") and (III) if such
  issuance occurs during the 365-day period commencing on the Effective Time,
  the Board by the affirmative vote of a majority of the votes entitled to be
  cast by the Directors present at a meeting of the Board at which a quorum
  is present, which vote must include the affirmative votes of both Union
  Directors, approves     
 
                                       70
<PAGE>
 
     
  an equitable adjustment to the conversion rate applicable to the conversion
  of the ESOP Preferred Stock into New Shares, (B) three-quarters of votes
  entitled to be cast by the entire Board, including all the Independent
  Directors, determines (I) that the Company is insolvent (or, absent a
  material positive change in the Company's results of operations over the
  immediately succeeding 90 days from the results contained in the Company's
  regularly prepared projections, that the Company will become insolvent
  within 90 days), which determination is confirmed by written opinions of
  two nationally recognized investment banking firms that further opine
  (giving effect to the facts and circumstances applicable to the Company,
  including discussions with prospective equity investors) that the sale of
  equity securities is necessary to avoid or remedy such insolvency (the
  "Bankruptcy Opinions") and (II) that, after giving effect to the proposed
  issuance of additional equity securities (the "Permitted Bankruptcy
  Equity"), the Company would no longer be or not become "insolvent" in the
  time frame referred to in the Bankruptcy Opinions (the "Solvency
  Determination") and such issuance of Permitted Bankruptcy Equity satisfies
  the following three conditions: (X) such issuance does not exceed the
  amount determined by the Board to be reasonably necessary to allow the
  Board to make the Solvency Determination, (Y) a binding commitment for the
  sale of such Permitted Bankruptcy Equity is entered into within 90 days of
  the delivery of the Bankruptcy Opinions and (Z) the terms of the First
  Refusal Agreement have been complied with in all material respects by the
  Company, or (C) such issuance is pursuant to (I) the exercise, conversion
  or exchange of equity securities outstanding immediately prior to the
  Effective Time, (II) the Company's 1981 Stock Program, 1988 Restricted
  Stock Plan or Incentive Plan, each as amended in accordance with the Plan
  of Recapitalization, (III) the UAL Corporation 1992 Stock Plan for Outside
  Directors or (IV) any other equity incentive compensation plan approved by
  the affirmative vote of three quarters of the votes entitled to be cast by
  the entire Board, including all the Independent Directors.     
 
 Special Voting Provisions with Respect to Purchase and Sale of Common Stock
   
  Until the Sunset, any purchases of New Shares by the Company (other than to
fulfill its obligations to issue or retain New Shares in connection with the
exercise of employee options issued pursuant to employee benefit plans or to
retain New Shares in connection with tax withholding obligations in connection
with the exercise of employee options or restricted stock), or any sale by the
Company of any New Shares to a Company sponsored pension, retirement or other
employee benefit plan for the account of employees (other than pursuant to the
First Refusal Agreement or in connection with the creation and operation of the
ESOPs to which the ESOP Preferred Stock is issued), whether for cash or non-
cash consideration, including, without limitation, employee concessions, must
be approved by a majority of the Board, including at least 80% of the votes of
the Public Directors.     
 
 Rights Plan
   
  The Rights Agreement between the Company and First Chicago Trust Company of
New York, dated as of December 11, 1986, as amended (the "Rights Agreement"),
which currently contains a "flip-in" trigger for the acquisition of 15% or more
of the Old Shares, will be amended to provide that the transactions
contemplated by the Recapitalization Agreement will not result in the Rights
(as defined in the Rights Agreement) being triggered. In addition, effective
immediately prior to the Effective Time, the Rights Agreement will be amended
to provide that the ESOP Preferred Stock will have the same number of attached
Rights associated as would be attached to the same number of New Shares to
which the ESOP Preferred Stock will be convertible. See "DESCRIPTION OF
SECURITIES--The Common Stock, the Series A Preferred Stock and the Junior
Participating Preferred Stock--Junior Participating Preferred Stock--Preferred
Share Purchase Rights."     
 
 Nondilution
   
  As described under "DESCRIPTION OF SECURITIES--The Voting Preferred Stock--
Voting Rights," at the Effective Time, the holders of Voting Preferred Stock
will vote as a single class with the New Shares and will represent
approximately 55% of the votes to be cast on matters submitted to the vote of
the     
 
                                       71
<PAGE>
 
   
New Shares and Voting Preferred Stock (other than the election of Directors and
such matters for which a vote by separate class is required under the DGCL).
The number of votes represented by such Voting Preferred Stock is subject to
increase at the first anniversary of the Effective Time based on the market
price of the New Shares during the first year following the Effective Time as
described in "--Establishment of ESOPs--Additional Shares." The Voting
Preferred Stock will generally continue to represent approximately 55% of the
aggregate voting power of the New Shares and the Voting Preferred Stock, as
adjusted under certain circumstances, until the Sunset.     
   
 Sunset     
   
  The "Sunset" will occur when (i) the New Shares issuable upon conversion of
the outstanding ESOP Preferred Stock, plus (ii) any Common Equity and Book-
Entry Shares (as defined below, see "--Establishment of ESOPs--Initial Sale of
ESOP Preferred Stock") held in the ESOPs, in any other employee benefit plans
sponsored by the Company or any of its subsidiaries for the benefit of its
employees, represent, in the aggregate, less than 20% of the Common Equity and
Book-Entry Shares of the Company. "Common Equity" is defined as, in the
aggregate, the New Shares outstanding at the time in question and the New
Shares issuable upon conversion of the ESOP Preferred Stock outstanding at the
time in question, together with the New Shares represented by the Permitted
Bankruptcy Equity outstanding at the time in question, if any, but excluding
any equity or equity equivalent securities (other than Permitted Bankruptcy
Equity) issued in connection with a Non-Dilutive Issuance, including, without
limitation, any equity or equity equivalent securities outstanding immediately
prior to the Effective Time that were not included in the calculation of the
Fully Diluted Old Shares as set forth and defined in "--Terms and Conditions--
General."     
 
  If the Sunset occurs, the Company will file a restated certificate of
incorporation providing for more customary corporate governance provisions, the
number of Directors will remain at twelve (of which three will be Employee
Directors), the Outside Public Director Nomination Committee will nominate the
Board's nominees for election of directors (other than the Employee Directors)
to be elected by the stockholders at a meeting which will be held promptly
thereafter and upon the effectiveness of such election the term of the then
incumbent Directors will terminate, and there will be no special director or
voting rights, except that (a) the ALPA Director will be elected by the holder
of the Class Pilot MEC Preferred Stock until there are no longer any persons
represented by ALPA (or any successor organization) employed by the Company or
any affiliate (the "ALPA Termination Date"), the IAM Director will be elected
by the holder of the Class IAM Preferred Stock until there are no longer any
persons represented by the IAM (or any successor organization) employed by the
Company or any affiliate (the "IAM Termination Date") and the Salaried and
Management Director will be elected by the holders of the Class SAM Preferred
Stock until the earlier of the ALPA Termination Date and the IAM Termination
Date, each voting separately in a class, and (b) the Union Directors would
continue to serve on Committees as provided below.
   
  Under current actuarial assumptions, the Company estimates that the Sunset
will occur in the year 2016 if no additional purchases were made by eligible
employee trusts and retirement plans. However, employees have the right to, and
may be expected to, make additional purchases through such trusts and plans
that will have the effect of delaying the Sunset. In certain circumstances
described under "DESCRIPTION OF SECURITIES--The Director Preferred Stock--
Uninstructed Trustee Action," the Sunset may not occur until 2010 even though
the conditions for the Sunset have occurred.     
 
 Committees
 
  The Restated Certificate provides that until the Sunset the following
committees will constitute the Board Committees: the Audit Committee, the
Competitive Action Plan ("CAP") Committee, the Compensation Committee, the
Compensation Administration Committee, the Executive Committee, the Independent
Director Nomination Committee, the Labor Committee, the Outside Public Director
Nomination Committee and the Transaction Committee (collectively, the
"Committees"). In addition, the Board may, by resolution passed by the
affirmative vote of 80% of the votes of the entire Board, including
 
                                       72
<PAGE>
 
the affirmative vote of at least one Union Director, designate one or more
other committees of the Board. Except as provided below, any act of a Committee
will require the affirmative vote of a majority of the votes entitled to be
cast by the Directors present at a meeting of such Committee and entitled to
vote on the matter in question. The Restated Certificate contains certain
provisions relating to the required quorum for committee action.
 
  The Audit Committee will consist of the four Independent Directors and the
three Outside Public Directors or such fewer number of such Directors (in as
nearly as practicable that same proportion of Independent Directors and Outside
Public Directors) as shall qualify for audit committee membership under
applicable rules of the securities exchanges or other similar trading market on
which the New Shares are traded. The Audit Committee will be primarily
concerned with (i) reviewing the professional services and independence of the
Company's independent auditors and the scope of the annual external audit as
recommended by the independent auditors, (ii) ensuring that the scope of the
annual external audit is sufficiently comprehensive, (iii) reviewing, in
consultation with the independent auditors and the internal auditors, the plan
and results of the annual external audit, the adequacy of the Company's
internal control systems and the results of the Company's internal audits, and
(iv) reviewing, with management and the independent auditors, the Company's
annual financial statements, financial reporting practices and the results of
each external audit. The Audit Committee will also have the authority to
consider the qualifications of the Company's independent auditors, to make
recommendations to the Board as to their selection and to review and resolve
disputes between such independent auditors and management relating to the
preparation of the annual financial statements.
   
  The CAP Committee will consist of eight Directors, including four Public
Directors, two Independent Directors and the two Union Directors. Of the four
Public Directors, three will be Outside Public Directors and one shall be the
CEO (if the CEO is a Public Director). The two Independent Director members
shall be appointed by the Independent Director Nomination Committee which
appointment will require the affirmative vote of all of the votes entitled to
be cast by the Independent Directors. The function of the CAP Committee will be
to oversee implementation of the Company's Competitive Action Plan. The CAP
Committee will have the exclusive authority, acting for and on behalf of the
Board and consistent with the protection of the interests of the holders of New
Shares, to approve on behalf of the Company any and all modifications of or
amendments to the Competitive Action Plan. However, to the extent such
modifications or amendments relate to changes to any provision of the revised
Collective Bargaining Agreements with the IAM and ALPA, the two Union Directors
on the CAP Committee will neither be entitled to vote nor be counted in
determining the presence of a quorum of such committee in connection therewith.
Notwithstanding the foregoing, only the Labor Committee may approve on behalf
of the Company any such changes to such Collective Bargaining Agreements. In
addition, the CAP Committee will have the exclusive authority, acting for and
on behalf of the Board, to approve on behalf of the Company any and all
modifications of or amendments to the salaried and management employee
investment described in "--Investment for Salaried and Management Employees".
Such modifications or amendments must be approved by the affirmative vote of at
least a majority of the votes of the entire CAP Committee, including at least
two Union Directors and all of the Outside Public Directors.     
 
  The Compensation Committee will consist of seven Directors, including two
Independent Directors, two Public Directors and the three Employee Directors.
Of the two Public Directors, one will be an Outside Public Director appointed
by the Outside Public Director Nomination Committee, and one will be the CEO
(if the CEO is a Public Director). The two Independent Directors members will
be appointed by the unanimous approval of the Independent Director Nomination
Committee. The principal functions of the Compensation Committee will be to
review and recommend to the Board the compensation and benefit arrangements to
be established for the officers of the Company and to review general policy
matters relating to compensation and benefit arrangements of non-union
employees of the Company. The Compensation Committee will also administer the
stock option plans and executive compensation programs of the Company,
including bonus and incentive plans applicable to officers and key employees of
the Company. Subject to the
 
                                       73
<PAGE>
 
   
final approval of the Compensation Committee (except as described in the
following paragraph), the Compensation Committee may delegate to the
Compensation Administration Committee specific responsibilities with respect to
the compensation of the CEO.     
   
  The Compensation Administration Committee will consist of two Independent
Directors and one Outside Public Director, each of whom will be (a) a
"disinterested person" or "disinterested administrator" or any related
successor concept under Rule 16b-3 (or any successor provision) promulgated
pursuant to Section 16 of the Exchange Act and (b) an "outside director" or any
related successor concept under Section 162(m) (or any successor provision) of
the Code. The Outside Public Director will be appointed by the Outside Public
Director Nomination Committee. The two Independent Directors will be appointed
by the Independent Director Nomination Committee, which appointment shall
require the affirmative vote of all the Independent Directors. The principal
function of the Compensation Administration Committee will be to administer the
stock option plans and executive compensation programs of the Company to the
extent such functions cannot or are not appropriate to be performed by the
Compensation Committee in light of any provision of the Internal Revenue Code,
the securities laws, any other applicable law or any regulations promulgated
under any of the foregoing. Any action of the Compensation Administration
Committee must also be approved by the Compensation Committee, unless such
approval would prevent a stock option plan that is intended to qualify under
Rule 16b-3 (or any successor provision) from receiving the benefits of Rule
16b-3 or such approval would prevent an executive compensation program (on a
component thereof), that is intended to qualify for an exception under Section
162(m) (or any successor provision) from qualifying for such exception.     
   
  The Executive Committee will be comprised of two Independent Directors, two
Public Directors (the CEO, if the CEO is a Public Director, and one Outside
Public Director) and two Union Directors. Subject to the DGCL, the Executive
Committee will have all the powers of the Board to manage the affairs of the
Company except that it would not have the authority to act with respect to any
of the "Extraordinary Matters" discussed above, to take any action as to
matters specifically vested in other Committees or take any action that may be
taken by the Board only with a vote greater than or additional to a majority of
the Board. In the event a new CEO is to be selected prior to the Sunset, the
Executive Committee will function as a search committee to identify a successor
CEO.     
 
  The Labor Committee will consist of three or more Directors, including one
Outside Public Director, at least one Independent Director and at least one
other Director, as designated by the Board, but will not include any Employee
Directors. The Labor Committee will have the exclusive authority on behalf of
the Board to approve on behalf of the Company the entering of, or any
modification or amendment to, a collective bargaining agreement to which the
Company or any of its subsidiaries is a party.
 
  The Transaction Committee will consist of seven Directors, consisting of the
four Independent Directors and the three Outside Public Directors. The function
of the Transaction Committee will be to evaluate and advise the Board with
respect to any proposed merger or consolidation of the Company or any of its
Subsidiaries with or into, the sale, lease or exchange of all or substantially
all of the Company's or any of its Subsidiaries' property or assets to, or a
significant business transaction with any Labor Affiliate.
 
 Amendment and Restatement of the Bylaws
   
  Pursuant to the Plan of Recapitalization the Company's Bylaws will be amended
and restated (the "Restated Bylaws"). The Restated Bylaws provide that until
the Sunset many matters will be governed by the Restated Certificate including,
among others: (i) quorum requirements at any meeting of the stockholders, the
Board or any Board Committee; (ii) number, composition and term of office of
directors; (iii) removal of Directors; (iv) filling of vacancies on the Board
and on Board Committees; (v) designation of Board Committees; (vi) the
composition, function and powers of the Executive Committee; (vii) the
appointment, term of office, filling of vacancies and removal of officers of
the Company; and (viii) any substantive     
 
                                       74
<PAGE>
 
   
amendment to the Restated Bylaws. Furthermore, the Restated Bylaws provide
that, subject to certain exceptions, following the Sunset many provisions of
the existing Bylaws of the Company will be reinstated.     
   
  In addition, the Restated Bylaws provide, among other things, for other
changes to the existing Bylaws including, but not limited to the following: (i)
the ability, until the Sunset, of any two directors, the CEO or the secretary
of the Company to call a special meeting of the Board; (ii) until the Sunset,
subject to the fiduciary obligations of the directors, the CEO will be elected
as one of the Management Public Directors; (iii) the term of the CEO (other
than Mr. Greenwald as the initial CEO) will automatically terminate if he is
not elected as Management Public Director by the stockholders at the first
meeting of stockholders for the election of directors at which he is eligible
for nomination as a Management Public Director; and (iv) until the Sunset, non-
substantive amendments to the Restated Bylaws may be adopted either by a
majority vote of the entire Board or by 75% in the voting power of the stock
entitled to vote at a stockholder meeting in which a quorum is present. In
addition, the Restated Bylaws contain other procedural sections, some of which
operate only until the Sunset and some of which become operative only after the
Sunset.     
   
TERMS AND CONDITIONS     
 
 General
   
  The Plan of Recapitalization provides for the reclassification of the Old
Shares and other amendments to the Company's Certificate of Incorporation and
Bylaws. Immediately prior to the Effective Time each outstanding Old Share,
including each share of restricted stock issued pursuant to the 1988 Restricted
Stock Plan (which will vest upon the Effective Time if not vested prior
thereto), together with up to 1,000,000 Old Shares held by the Company as
treasury stock or owned by any wholly-owned subsidiary of the Company
immediately prior to the Effective Time, will, without any further action on
the part of the holder thereof, be reclassified as, and converted into, (i) one
half (0.5) of a New Share, and     
     
    (a) if the Offerings are consummated, one one-thousandth of a share of
  Series E Redeemable Preferred Stock, which one one-thousandth of a share
  will be redeemed immediately after issuance, for an amount of cash equal to
  the sum of (A) $25.80, (B) the proceeds (without deducting the underwriting
  discount and other costs) from the sale by United of $15.55 face amount of
  Series A Debentures and $15.55 face amount of Series B Debentures and (C)
  the proceeds (without deducting the underwriting discount and other costs)
  from the sale by the Company of 1.244 Depositary Preferred Shares
  representing interests in $31.10 liquidation preference of Public Preferred
  Stock (under various circumstances the proceeds of the sale of the
  Debentures and the Depositary Preferred Shares could be less than their
  face amount) or     
     
    (b) if the Offerings are not consummated, one one-thousandth of a share
  of Series D Preferred Stock which one one-thousandth of a share will be
  redeemed immediately after issuance for (i) $25.80 in cash, (ii) $15.55
  face amount of Series A Debentures, (iii) $15.55 face amount of Series B
  Debentures and (iv) 1.244 Depositary Preferred Shares representing
  interests in $31.10 liquidation preference of Public Preferred Stock.     
   
  The New Shares and cash distributed in respect of Old Shares if the Offerings
are consummated are referred to herein as the "Proceeds Recapitalization
Consideration." The New Shares, cash, Debentures and Depositary Preferred
Shares distributed in respect of Old Shares if the Offerings are not
consummated and are referred to herein as the "Mixed Recapitalization
Consideration." The Proceeds Recapitalization Consideration and the Mixed
Recapitalization Consideration are each sometimes referred to herein as the
"Recapitalization Consideration." The New Shares to be issued in the
Recapitalization will represent an equity interest (based on the Fully Diluted
Old Shares described below and taking into account the 0.5 common stock
exchange ratio and taking into account the shares of ESOP Preferred Stock the
Company is initially obligated to issue) immediately after the Recapitalization
of 45% of one Old Share's current percentage equity interest. Such equity
interest is subject to adjustment as described below under "--Establishment of
ESOPs--Additional Shares."     
       
                                       75
<PAGE>
 
   
  "Fully Diluted Old Shares" were calculated as follows: the sum of (i) Old
Shares outstanding (net of unvested restricted shares), (ii) unvested
restricted shares, (iii) net options shares issued assuming the treasury stock
method of accounting (pursuant to which the deemed proceeds to the Company from
the deemed     
       
   
exercise of in-the-money options are applied to repurchase shares for the
treasury at an assumed market price per Old Share of $173) and (iv) shares
issuable upon conversion of the Series A Preferred Stock. Due to their high
conversion premium, the Air Wis Services, Inc. 7 3/4% Convertible Subordinated
Debentures Due 2010 and Air Wis Services, Inc. 8 1/2% Convertible Subordinated
Notes Due 1995 were not assumed to be converted and were not included in the
calculation of Fully Diluted Old Shares. The number of Fully Diluted Old
Shares, as shown below, is fixed for purposes of the Plan of Recapitalization
and the issuance of shares of ESOP Preferred Stock to the ESOPs although the
actual number of Old Shares that are reclassified pursuant to the
Recapitalization may change due to vesting of restricted stock and the exercise
of options:     
 
<TABLE>
     <S>                                                              <C>
     Old Shares (net)................................................ 24,450,896
     Unvested restricted shares......................................    119,643
     Option shares (net).............................................    521,780
     Old Shares upon conversion of Series A Preferred Stock..........  3,833,866
                                                                      ----------
     Fully Diluted Old Shares........................................ 28,926,185
                                                                      ----------
</TABLE>
   
  Because the calculation of Fully Diluted Old Shares is based on the exercise
of net option shares (using the treasury stock method) and the conversion of
all the Series A Preferred Stock, neither of which is expected to occur at the
Effective Time, the New Shares then outstanding are expected to represent less
than 47% of the Common Equity of the Company (taking into account the New
Shares and the ESOP Preferred Stock only) at the Effective Time.     
   
  As contemplated by the Plan of Recapitalization, the Company has elected to
issue Depositary Preferred Shares, each representing an interest in one one-
thousandth of a share of Public Preferred Stock, which is the equivalent of $25
liquidation preference of Public Preferred Stock. Each share of Public
Preferred Stock will have a liquidation preference of $25,000. See "Description
of Securities--The Depositary Preferred Stock."     
 
 Effective Time
   
  The Recapitalization, the Stock Issuance, the amendments to the 1981 Stock
Program, the 1988 Restricted Stock Plan and the Incentive Plan and the revised
Collective Bargaining Agreements with ALPA and the IAM will become effective at
such time as the Restated Certificate, which provides for the reclassification
of the Old Shares, is duly filed with the Secretary of State of the State of
Delaware or at such later time as may be mutually agreed upon by the Company
and each of ALPA and the IAM and as is specified in the Restated Certificate
(the "Effective Time"). The filing of the Restated Certificate is currently
anticipated to be made as promptly as practicable after the Meeting. Such
filing shall be made, however, only upon satisfaction or, where permissible,
waiver of all conditions contained in the Plan of Recapitalization and provided
that the Plan of Recapitalization has not been terminated. See "--Terms and
Conditions" and "--Termination." If the Offerings are consummated, it is
expected that they will be consummated at or prior to the Effective Time.     
 
 Payment for Shares
 
  As soon as practicable after the Effective Time, the Company will send or
cause First Chicago Trust Company of New York (the "Exchange Agent") to send
and otherwise make available a letter of transmittal to each record holder of
Old Shares as of the Effective Time to be used to transmit a certificate or
certificates that immediately prior to the Effective Time represented Old
Shares (an "Old Certificate" or "Old Certificates") to the Exchange Agent. Such
letter of transmittal will advise the holder of the effectiveness of the
Recapitalization and the procedures for surrendering to the Exchange Agent the
Old Certificate or Certificates for exchange into Recapitalization
Consideration and will specify that the delivery will be effected
 
                                       76
<PAGE>
 
and the risk of loss and title will pass, only upon proper delivery of the Old
Certificate or Certificates to the Exchange Agent. Stockholders should
surrender the Old Certificate or Certificates only together with a letter of
transmittal. STOCKHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THE
ENCLOSED PROXY CARD.
 
  Each holder of Old Shares that have been converted into the right to receive
the Recapitalization Consideration, upon surrender to the Exchange Agent of the
Old Certificate or Certificates together with a properly completed letter of
transmittal, will be entitled to receive the Recapitalization Consideration for
each Old Share formerly represented by such Old Certificate. Until so
surrendered, each Old Certificate will, after the Effective Time, represent for
all purposes only the right to receive such Recapitalization Consideration. If
any payment of the Recapitalization Consideration is to be made to a person
other than the registered holder of the Old Shares, the Old Certificates so
surrendered must be properly endorsed or otherwise be in proper form for
transfer, and any applicable transfer or other taxes must have been paid to the
Exchange Agent by the person requesting such payment or such person must have
established to the satisfaction of the Exchange Agent that such tax has been
paid or is not payable.
 
  In the event any Old Certificate is lost, stolen or destroyed, based on an
affidavit to that fact by the person claiming such Old Certificate to be lost,
stolen or destroyed, the Company will issue in exchange for such lost, stolen
or destroyed Old Certificate the Recapitalization Consideration deliverable in
respect thereof. When authorizing such issue of the Recapitalization
Consideration in exchange therefor, the Company may, in its discretion and as a
condition precedent to the issuance thereof, require the person claiming
ownership of such lost, stolen or destroyed Old Certificates to give the
Company a bond in such sum as it may direct, or otherwise indemnify the Company
in a manner satisfactory to it, against any claim that may be made against the
Company with respect to the Old Certificates alleged to have been lost, stolen
or destroyed.
 
  After the Effective Time, there will be no further registration of transfers
of Old Shares. If, after the Effective Time, Old Certificates representing Old
Shares are presented to the Company or its transfer agent, such Old
Certificates will be cancelled and exchanged for the Recapitalization
Consideration.
   
  Fractional New Shares and, if the Offerings are not consummated, fractional
Depositary Preferred Shares (based on $25 of liquidation preference value per
Whole Depositary Preferred Share) and fractional Debentures (based on $100
principle amount per whole Debenture) will not be issued as part of the
Recapitalization and such fractional interests will not entitle the beneficial
or record owner thereof to any rights of a stockholder or creditor of the
Company. In lieu of any fractional New Shares and, if applicable fractional
Depositary Preferred Shares and fractional Debentures to which a former holder
of Old Shares otherwise would be entitled, such holder will be entitled to
receive from the Exchange Agent a cash payment based on pro-rata distribution
of the proceeds received by the Exchange Agent from the sale of the aggregate
fractional New Shares, fractional Depositary Preferred Shares and fractional
Debentures. Such cash payments will be made to each such holder of Old Shares
only upon proper surrender of such holder's Old Certificates formerly
representing Old Shares, together with a properly completed and duly executed
transmittal letter and any other required documents.     
   
  All Recapitalization Consideration, including cash in lieu of fractional
interests, if not claimed at the first anniversary of the Effective Time, will
be transferred by the Exchange Agent to the Company, after which time persons
entitled thereto may look, subject to applicable escheat and other similar
laws, only to the Company for payment thereof. No interest will be paid or
accrued on any portion of the Recapitalization Consideration, including cash in
lieu of fractional interests. No dividends or other distributions declared or
made after the Effective Time with respect to New Shares with a record date
after the Effective Time will be paid to the holder of any unsurrendered Old
Certificate or Certificates with respect to the New Share that such holder is
entitled to receive until the holder of such Old Certificate or Certificates
has properly surrendered the same.     
 
 Stock Options
 
  Upon consummation of the Recapitalization, each outstanding employee stock
option of the Company granted under any employee stock option or compensation
plan or arrangement of the Company will remain
 
                                       77
<PAGE>
 
   
outstanding, each such option then held by employees or former employees of
the Company, whether or not then vested or exercisable immediately prior to
the Effective Time (collectively, the "Options"), if provided by the terms
thereof (or if accelerated in accordance with the relevant plan) will become
fully vested and exercisable and after the Effective Time each option will
thereafter represent the right to receive, in exchange for the aggregate
exercise price for such option, the Recapitalization Consideration with
respect to each Old Share that such holder would have been entitled to receive
had such holder been vested in such option and exercised such option in full
immediately prior to the Effective Time. If the Offerings are consummated,
holders of Options who exercise their Options after the Effective Time will
receive the Proceeds Recapitalization Consideration upon such exercise, and if
the Offerings are not consummated, they will receive the Mixed
Recapitalization Consideration upon such exercise.     
 
 Convertible Company Securities
   
  Each share of Series A Preferred Stock and each of the Air Wis Services,
Inc. 7 3/4% Convertible Subordinated Debentures Due 2010 and the Air Wis
Services, Inc. 8 1/2% Convertible Subordinated Notes Due 1995 (collectively,
the "Convertible Company Securities") outstanding immediately prior to the
Effective Time will remain outstanding, and each holder of any such
Convertible Company Security will have the right to receive the
Recapitalization Consideration with respect to each Old Share that such holder
would have been entitled to receive upon conversion had such holder converted
such Convertible Company Security in full immediately prior to the Effective
Time. If the Offerings are consummated, holders of Convertible Company
Securities who convert their securities after the Effective Time will receive
the Proceeds Recapitalization Consideration upon such conversion, and if the
Offerings are not consummated, they will receive the Mixed Recapitalization
Consideration upon such conversion.     
 
 Treasury Shares
   
  Pursuant to the Plan of Recapitalization, each Old Share held by the Company
as treasury stock or owned by any wholly-owned subsidiary of the Company
immediately prior to the Effective Time (the "Treasury Shares"), up to a
maximum of 1,000,000 Treasury Shares (the "Retained Treasury Shares"), will be
reclassified and converted into the Recapitalization Consideration, with all
Treasury Shares in excess of 1,000,000 being surrendered for cancellation
immediately prior to the Effective Time and no payment shall be made with
respect thereto. Immediately following the Effective Time, the Company and
each of its wholly owned subsidiaries will surrender for cancellation the
Redeemable Preferred Stock received upon reclassification of the Retained
Treasury Shares and no payment will be made in respect thereof.     
 
 Pricing the Securities
   
  Under the Plan of Recapitalization, the interest rate on the Series A
Debentures has been fixed provisionally at 9.00%, the interest rate on the
Series B Debentures has been fixed provisionally at 9.70% and the dividend
rate on the Public Preferred Stock has been fixed provisionally at 10.25% (the
"Initial Pricing"). On the Trading Day immediately preceding the Announcement
Date (as defined below), CS First Boston (in consultation with Lazard) on
behalf of the Company and Keilin & Bloom (or such other investment banking
firm as may be reasonably selected by the Unions) on behalf of the Unions (the
"Primary Banking Firms") will seek to mutually determine the interest or
dividend rate that each of the Debentures and the Public Preferred Stock
should bear in order for the Debentures and Depositary Preferred Shares to
trade at par as of the close of business, New York time, on the last day on
which the NYSE is open for business ("Trading Day") immediately preceding the
Announcement Date, assuming that the Debentures or the Depositary Preferred
Shares were fully distributed on such Trading Day. "Announcement Date" means a
Trading Day that will be not fewer than five calendar days nor more than ten
calendar days preceding the date of the Meeting, such date to be disclosed to
the Unions not fewer than ten calendar days prior thereto. If the Primary
Banking Firms are unable to agree on the applicable rate of the Public
Preferred Stock and the Debentures (the "Applicable Rates") with respect to a
specified security, then (i) a third financial advisor identified by the     
 
                                      78
<PAGE>
 
   
Company and the Unions (the "Deadlock Firm"), will render its opinion, on the
Trading Day immediately preceding the Announcement Date, as to the Applicable
Rate with respect to such securities, and (ii) the Applicable Rate with
respect to such security or securities will be the average of the two closest
rates specified in the opinions of the Primary Banking Firms and the Deadlock
Firm, rounded to the nearest one one-hundredth of a percent, provided,
however, that, while there is no limitation on a downward adjustment, in no
event shall the Applicable Rate with respect to the Debentures or the Public
Preferred Stock exceed 10.125% in the case of the Series A Debentures, 10.825%
in the case of the Series B Debenture and 11.375% in the case of the Public
Preferred Stock. See "SPECIAL FACTORS--Certain Risk Factors--Investment
Values; Future Investments."     
   
  The underwriting agreements relating to the Offerings will provide that if
the Offerings are consummated, the interest rates on the Debentures and the
dividend rate on the Preferred Stock may be adjusted to permit the Debentures
and the Depositary Preferred Shares to be sold at or closer to par, but if
that is done, the principal amount of the series of Debentures affected or the
number of Depositary Preferred Shares representing interests in the Public
Preferred Stock, as the case may be, will be reduced so that the aggregate
amount of interest payable annually by United on the Debentures or the
aggregate amount of dividends payable annually by the Company on the Public
Preferred Stock will not exceed certain maximum amounts calculated in
reference to such caps. If the Offerings are not consummated, the interest
rates borne by the Debentures and the dividend rate borne by the Public
Preferred Stock will be subject to the caps. See "THE PLAN OF
RECAPITALIZATION--Terms and Conditions--Pricing the Securities."     
   
  On the Announcement Date, the Company will issue a press release setting
forth the adjusted rate for the Debentures and the Public Preferred Stock and,
on the first business day following the Announcement Date, will publish such
rates in an advertisement in The Wall Street Journal. A toll-free number (800-
223-2064) has been established from which all holders of Old Shares can obtain
general information concerning the Announcement Date. As of the Announcement
Date, holders of the Old Shares can call the toll-free number to obtain
definitive pricing information. See also "SPECIAL FACTORS--Certain Risk
Factors--Pricing the Public Preferred and the Debentures."     
   
  The information concerning the pricing will include a statement of whether
the Company expects the Offerings to be consummated and, if so, the amount of
the cash proceeds expected to be received from the sale of the Debentures and
Depositary Preferred Shares that are issuable in respect of each Old Share. A
statement that the Company expects the Offerings to be consummated will not be
an assurance that the Offerings will be consummated.     
 
  The provisional rates of interest that the Debentures will bear and the
maximum rates of interest that they may bear upon adjustment are based upon
the assumption that the Debentures will not be callable prior to their
respective stated maturities. The Plan of Recapitalization provides that the
Unions may request, a reasonable period of time prior to the Announcement
Date, that either or both of the series of Debentures may be callable pursuant
to redemption provisions to be established for each of the Debentures. If so
requested, the Primary Banking Firms will establish the incremental increase
in pricing resulting from the addition of the call feature on either or both
of the series of Debentures, as the case may be, above the Applicable Rate,
with any disagreement to be resolved with the assistance of the Deadlock Firm.
The Coalition may withdraw the request for a call feature at any time up to
the issuance of the press release on the Announcement Date.
 
 Record and Payment Dates
   
  If the Offerings are not consummated, the quarterly record dates (and
corresponding dividend payment dates) for the payment of dividends on the
Public Preferred Stock (through the Depositary Preferred Shares) will be the
same as the quarterly record dates (and corresponding dividend payment dates)
for the payment of dividends on the Series A Preferred Stock and the semi-
annual record dates (and corresponding interest payment dates) for the payment
of interest on the Debentures will be the same as two of the quarterly record
    
                                      79
<PAGE>
 
dates (and corresponding dividend payment dates) for the payment of dividends
on the Series A Preferred Stock.
 
 Purchase of ESOP Preferred Stock
   
  The Preferred Stock Purchase Agreement, originally dated as of March 25, 1994
and amended as of May  , 1994, between the Company and the ESOP Trustee (the
"ESOP Stock Purchase Agreement"), provides for the initial purchase by the
Qualified ESOP (as defined below, see "Establishment of ESOPs--Sales of ESOP
Preferred Stock") of the Class 1 ESOP Preferred Stock for a price equal to 1.38
times the average closing price of the New Shares as of the Effective Time,
which average closing price will be determined as the greater of the value of a
New Share at the Effective Time or 98% of two times the average price of an Old
Share in the five trading days prior to the Effective Time, less the value of
the Recapitalization Consideration (other than New Shares) issued with respect
to an Old Share at the Effective Time. See "--Establishment of ESOPs--Sales of
ESOP Preferred Stock." The ESOP Stock Purchase Agreement also provides that
additional sales of Class 1 ESOP Convertible Preferred Stock will be made to
the ESOP Trustee on the first day of the thirteenth month after the Effective
Time (or, if earlier, September 1, 1995), on each of the next four
anniversaries of such date, and on January 1, 2000. The price for the
subsequent sales will be as agreed upon between the Company and the ESOP
Trustee. The Company may make the subsequent sales at earlier times, provided
that earlier sales shall not alter the timing of the allocation of shares to
participants' accounts. If agreements cannot be reached with the ESOP Trustee
to make the subsequent sales, the Company will consolidate the shares which
would have been sold. For additional information concerning the purchase of the
Class 1 ESOP Preferred Stock and for information on the Class 2 ESOP Preferred
Stock, see "--Establishment of ESOPs--Sales of ESOP Preferred Stock." In
addition, pursuant to the Plan of Recapitalization, the dividend rate on the
Class 1 ESOP Preferred Stock may not be more than 7% of the initial purchase
price, without the consent of ALPA the IAM.     
 
 Representations and Warranties
   
  The Plan of Recapitalization contains various customary representations and
warranties relating to, among other things, (a) on the part of the Company, as
to, (i) organization and similar corporate matters, (ii) authorization,
execution, delivery, performance and enforceability of the Plan of
Recapitalization and related matters, (iii) capital structure, (iv)
subsidiaries, (v) documents filed by the Company with the Commission and the
accuracy of information contained therein, (vi) absence of material changes
with respect to the business of the Company since December 31, 1993, (vii)
generally, subject to certain exceptions, compliance with the "status quo"
provisions of the Agreement in Principle which are substantially similar to the
provisions of the first paragraph below under "--Certain Covenants" during the
period from December 22, 1993 until March 25, 1994 and (viii) the opinion of
financial advisors as to the fairness of the Recapitalization Consideration,
and (b) on the part of each of the Unions, as to, (i) organization and similar
matters and (ii) authorization, execution, delivery, performance and
enforceability of the Plan of Recapitalization.     
 
 Certain Covenants
 
  Pursuant to the Plan of Recapitalization, the Company agreed that during the
period from the date of the Plan of Recapitalization until the Effective Time,
the Company and its subsidiaries will be subject to certain restrictions on
their conduct and will generally only take actions in the ordinary course of
business consistent with past practice; in particular, the Company and its
subsidiaries may not, among other things, without the prior written consent of
the Unions, subject to certain agreed upon exceptions: (i) issue, sell, dispose
of, pledge or otherwise encumber any equity securities of the Company or any
subsidiary (or securities exercisable into or for such securities), (ii)
reclassify, combine, split, subdivide, redeem, purchase or otherwise acquire
any securities of the Company, (iii) declare or pay any dividend or
distribution on the Old Shares, (iv) increase the compensation of any of its
directors, officers or key employees, or increase its expenses relating to
employee benefits, (v) incur any material amount of long-term indebtedness,
make any material
 
                                       80
<PAGE>
 
   
loans, advances or capital contributions to any other person, mortgage or
pledge any of its material assets or (vi) enter into any agreement or
arrangement to do any of the foregoing. The Company also agreed, among other
things, subject to certain exceptions until the Effective Time (i) not to take
any actions that would violate or be inconsistent with the job protection
provisions of the collective bargaining agreements with each of the Unions,
(ii) not to take any action relating to certain matters requiring supermajority
votes under the Restated Certificate (as discussed above under "--Revised
Governance Structure--Extraordinary Matters") and (iii) not to alter or amend
the Board's resolutions or any of its policies, practices, procedures or
employee benefit plans in any manner that would adversely affect the right or
ability of the employees of the Company or United to purchase equity securities
of the Company. The Company has agreed to restore certain severance benefits to
former employees of United who have been terminated as a result of the sale of
United's flight kitchens to Dobbs or Caterair. These severance benefits had
been in effect from December 22, 1993, upon execution of the Agreement in
Principle, until March 15, 1994, when the "status quo" provision of the
Agreement in Principle terminated.     
   
  In addition to the covenants described above, the Company agreed to take
actions that will facilitate the implementation of the Plan of
Recapitalization. In particular, the Company agreed, among other things, (i)
subject to receipt of updated fairness opinions from CS First Boston and
Lazard, to convene a meeting of stockholders to approve each of the Plan of
Recapitalization, the Restated Certificate, the election of the initial Public
Directors to the Board of Directors of the Company and the issuance of the ESOP
Preferred Stock as part of the Recapitalization (the "Shareholder Vote
Matters"), the approval of each such matter will be conditioned on approval of
all such matters, and amendments to the Company's 1981 Incentive Stock Plan and
1988 Restricted Stock Plan and Incentive Compensation Plan (the "Company Plan
Matters"), in connection with which the Company agreed to prepare, file with
the Commission and mail to its stockholders this Proxy Statement, (ii) to
provide each of ALPA and the IAM and their agents with reasonable access to
offices, employees, properties, books and records of the Company and its
Subsidiaries in connection with the Plan of Recapitalization and the
transactions contemplated thereby, (iii) subject to certain exceptions, not to
encourage, solicit, participate in or initiate discussions or negotiations
with, or provide any information to, any other person concerning any merger,
sale of assets, sale of, or tender or exchange offer for, shares of capital
stock or similar transaction, involving a change of control of the Company or
all or substantially all of the assets of the Company (an "Acquisition"), (iv)
to provide each of ALPA and the IAM with notices of certain significant events,
(v) to amend the directed account plans, 401(k) plans and stock purchase plan
maintained by the Company and United to permit employees of the Company and
United following the Effective Time to acquire, in addition to amounts held in
the ESOPs, the following securities: (X) up to the lesser of (1) 30% of the
outstanding New Shares held by persons other than the ESOPs and (2) 20% of the
aggregate number of outstanding New Shares and New Shares issuable upon
conversion of the ESOP Preferred Stock and (Y) except with respect to the
Company's stock purchase plan, up to (1) 20% of the outstanding Depositary
Preferred Shares, (2) 20% of the outstanding principal amount of Series A
Debentures and (3) 20% of the outstanding principal amount of Series B
Debentures, subject to the following additional limits: (A) no employee group
of the Company or its subsidiaries may individually acquire more than 10% of
any class of securities referred to in clause (X) and (Y) above through such
plans, (B) in the case of the directed account plans, no "Employee Group"
(defined as each of ALPA, the IAM and the salaried and management employees)
may individually acquire more than 2% of any such class of securities in any
monthly subscription period through such plans, (C) no Employee Group may
individually acquire more than 2% of the outstanding New Shares held by persons
other than the ESOPs (in addition to New Shares received in the
Recapitalization) through such plans during the six-month period beginning at
the Effective Time and (D) no New Shares may be acquired through such plans
during the six-month period ending on the last day of the Measuring Period,
(vi) to cause United to execute and deliver new collective bargaining
agreements or amendments to existing collective bargaining agreements with each
of ALPA and the IAM and to establish and cause United to establish appropriate
employment terms for the employees of the Company and United who perform the
functions currently performed by the salaried and management employees of the
Company and United, (vii) to retain an appraisal firm to provide an opinion in
writing as to whether the Company would have sufficient surplus under the DGCL
to permit the consummation of the     
 
                                       81
<PAGE>
 
   
Recapitalization (the "Solvency Letter") and that if the appraisal firm
concludes that sufficient surplus is so available, the Board will take all
lawful and appropriate action to revalue the Company's assets and liabilities
to permit consummation of the Recapitalization and (viii) to execute at the
Effective Time the Greenwald Agreement and to perform all of its obligations
under such agreement and to execute and deliver prior to the Effective Time all
the documents and agreements required to be executed and delivered by the
Company pursuant to the Plan of Recapitalization including documents and
agreements relating to the Debentures and the Depositary Preferred Shares, the
purchase of stock by the ESOPs (including the ESOP Stock Purchase Agreement),
the establishment of the ESOP Trusts, the retention and conduct of the Exchange
Agent, the subscription agreements relating to the various classes of stock to
be issued as part of the Recapitalization, the amendment to the Rights
Agreement, the Class I Stockholders' Agreement, the Class SAM Stockholders'
Agreement and the First Refusal Agreement (collectively, the "Closing
Agreements").     
 
  Pursuant to the Plan of Recapitalization, each of ALPA and the IAM agreed,
among other things, (i) prior to the Effective Time and after any termination
of the Plan of Recapitalization to hold confidential information received from
the Company and its subsidiaries in confidence, (ii) to execute and deliver
prior to the Effective Time the relevant Collective Bargaining Agreement
between each Union and the Company, (iii) not to nominate or cause to be
nominated any Outside Public Director and (iv) to use their best efforts to
cause any Independent Director vacancy to be filled.
 
  Pursuant to the Plan of Recapitalization, each of ALPA and the IAM and the
Company mutually agreed, among other things, (i) to use their best efforts to
consummate the Plan of Recapitalization and (ii) to cooperate in connection
with preparation and filing of documents with any governmental agency or
authority. In addition, if the AFA will agree to provide, in the sole judgment
of the Company, an investment equal to $416 million (present value in January
1994 dollars), then the parties, should an agreement be reached on all aspects
of the AFA's participation (e.g., governance), will revise all applicable
documents to reduce the investment period for ALPA, the IAM and the salaried
and management employees by nine months and to distribute 12.62 percentage
points of the ESOP Preferred Stock to the AFA on the following basis: 5.83
percentage points of the ALPA stock, 4.69 percentage points of the IAM stock,
and 2.10 percentage points of the salaried and management employee stock.

DGCL, (vii) the ESOP Trustee has received the written opinion of Houlihan

"--Establishment of ESOPs--Sales of ESOP Preferred Stock."

Unions to enter into the relevant revised Collective Bargaining Agreements at
the Effective Time are subject to the satisfaction of the following further
conditions, among others: (i) the Company will perform, both individually and

  Pursuant to the Plan of Recapitalization, the obligation of the Company to
file the Restated Certificate at the Effective Time is subject to the
satisfaction of the following further conditions, among others: (i) each Union
will perform, both individually and collectively, in all material respects, all
of its covenants, agreements or other obligations required to be performed by
it, under the Plan of Recapitalization, at or prior to the Effective Time, (ii)

  Consummation of the Recapitalization is not, however, conditioned upon the
consummation of either the UAL Preferred Offering or the United Debt Offering.
    
 Termination
   
  The Plan of Recapitalization will terminate and the Recapitalization will be
abandoned (notwithstanding any approval of the Shareholder Vote Matters by the
stockholders of the Company) if the Effective Time does not occur by 11:59 p.m.
on August 31, 1994 (the "Outside Termination Time"). In addition, the Plan of
Recapitalization may be terminated and the Recapitalization may be abandoned at
any time prior to the Outside Termination Time and prior to the Effective Time
(notwithstanding any approval of the Shareholder Vote Matters by the
stockholders of the Company) (a) by mutual written consent of each of ALPA and
the IAM and the Company, (b) by any of ALPA, the IAM or the Company if (i) the
stockholders of the Company do not approve the Shareholder Vote Matters at the
Meeting or (ii) any court of competent jurisdiction in the United States or
other United States Federal, state or local governmental body issues an order,
decree or ruling or take any other action restraining, enjoining or otherwise
prohibiting the Recapitalization and such order, decree, ruling or other action
has become final and nonappealable, (c) by either ALPA or the IAM if (i) the
Board withdraws or modifies in a manner materially adverse to such Union its
approval or recommendation of the Recapitalization or the Shareholder Vote
Matters or recommends, or fails to recommend against, another Acquisition, (ii)
the Board resolves to do any of the foregoing, (iii) the Company breaches,
either individually or collectively, in any material respect any of its
material representations, warranties, covenants or other agreements contained
in the Plan of Recapitalization, (iv) any person acquires "beneficial
ownership" (as defined in the Rights Agreement) or the right to acquire
beneficial ownership of, or any "group" (as such term is defined in Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder)
is formed that beneficially owns, or has the right to acquire beneficial
ownership of, more than 15% of the then outstanding Old Shares, or becomes an
"Acquiring Person" under the Rights Agreement or (v) there occurs a "Share
Acquisition Date" or "Distribution Date" as defined under the Rights Agreement
or (d) by the Company if (i) either ALPA or the IAM breaches, either
individually or collectively, in any material respect, any of their material
representations, warranties, covenants or other agreements contained in the
Plan of Recapitalization or (ii) the Board, acting in accordance with the
provisions of the Plan of Recapitalization relating to Acquisitions other than
the Recapitalization, withdraws or modifies in a manner adverse to either ALPA
or the IAM its approval or recommendation of the Recapitalization or recommends
another Acquisition, or resolves to do any of the foregoing.     
   
  Pursuant to the Plan of Recapitalization, if the Effective Time does not
occur on or before August 12, 1994, the Company may, by written notice to each
of the Unions, terminate its "status quo" obligations described above in the
first paragraph of "--Certain Covenants," provided that the Company's right to
so terminate its obligations will not be available in the event the Company's
failure to fulfill any obligation under the Plan of Recapitalization has been
the cause of or resulted in the failure of the Effective Time to occur on or
before such date. In addition, in the event the Company elects to terminate its
obligations in accordance with the preceding sentence, either of the Unions may
terminate the Plan of Recapitalization.     
 
 
                                       84
<PAGE>
 
  If the Plan of Recapitalization is terminated and abandoned as described in
the two preceding paragraphs, the Plan of Recapitalization, subject to certain
exceptions, will become void and of no effect with no liability on the part of
the Company or either of ALPA or the IAM. However, if the failure of the
Effective Time to occur at or prior to the Outside Termination Time results
from either (i) a material breach of a specific material representation or
warranty contained in the Plan of Recapitalization by one of the parties
thereto under circumstances where the breaching party had actual knowledge at
the date of the Plan of Recapitalization that such representation or warranty
was materially false or misleading or (ii) a material breach of a specific
material covenant (a breach described in clause (i) or (ii) as modified by
proviso (A) hereto, being called a "Willful Breach") and one of the other
parties thereto has established, as determined by a court of competent
jurisdiction, that such Willful Breach has occurred, the breaching party will
be liable to the other parties thereto, for proximate and provable damages
resulting from such Willful Breach (which shall include the reasonable fees
and expenses of such non-breaching parties, including reasonable attorney's
fees and expenses, incurred in connection with the transactions contemplated
thereby other than in connection with any litigation or other dispute between
or among parties thereto); provided (A) to the extent that the material breach
of a specific material covenant is not determinable solely by an objective
fact (e.g. any best efforts obligation or requirement of reasonableness) such
breach will be actionable thereunder only if the breaching party knew (or
demonstrated reckless disregard for whether) its action or failure to act was
in violation of such covenant and (B) such calculation of damages will not
include consequential or punitive damages and will be the sole and exclusive
remedy of the non-breaching parties in the event of a Willful Breach. With
respect to a Willful Breach, "knowledge" (or any corollary thereof) or
"reckless disregard" will mean the knowledge or reckless disregard of the
senior executives or officials of the Company and United or the Unions, as the
case may be, each of whom will conclusively be deemed to have read the Plan of
Recapitalization.
 
 Survival
   
  The representations and warranties and agreements contained in the Plan of
Recapitalization and in any certificate or other writing delivered pursuant
thereto will not survive the Effective Time unless expressly provided in such
agreement. The following agreements will survive the Effective Time:

Redeemable Preferred Stock, surrender and exchange of the Old Shares, issuance
of ESOP Preferred Stock, Director Preferred Stock and Additional Shares,

Certificate of Incorporation of United, restrictions on the ability of the
employees of the Company or United to purchase equity securities of the
Company, amendments to directed account plans, 401(k) plans and stock purchase
plans of the Company or United, employment terms of the salaried and
management employees, the employment of Greenwald and the Closing Agreements,
employee and director benefit plans, agreements, policies and arrangements of
the Company or United, prohibition against nominations of Public Directors by
the Unions, best efforts by the Unions to fill Independent Director vacancies,
certain matters relating to fees and expenses; and certain agreements relating
to indemnification (all such surviving agreements being referred to herein as
the "Express Agreements"). Except with respect to any Collective Bargaining
Agreement with the IAM and ALPA and the Express Agreements, from and after the
consummation of each of the transactions contemplated to take place at or
about the Effective Time, each of the parties to the Plan of Recapitalization
(in their capacities as such) will have fully released, discharged, waived and
renounced (collectively, the "Releases") any and all claims, controversies,
demands, rights, disputes and causes of action it may have had at or prior to
the Effective Time against, and will have agreed not to initiate any suit,
action or other proceeding involving, each of the other parties thereto, its
officials, officers, directors, employees, accountants, counsel, consultants,
advisors and agents and, if applicable, security holders relating to or
arising out of the Plan of Recapitalization or the transactions contemplated
thereby. However, the foregoing Releases do not apply to any claims,
controversies, demands, rights, disputes and causes of action arising from and
after the Effective Time (and based on facts and circumstances arising from
and after the Effective Time) under any of the documents, instruments or
transactions entered into, filed or effected in connection with the
Recapitalization (other than the Plan of Recapitalization, to the extent
provided in this paragraph).

 Amendments; No Waivers
 
  The Plan of Recapitalization provides that (a) any provision of the Plan of
Recapitalization may be amended or waived prior to the Effective Time if such
amendment or waiver is in writing and signed, in the case of an amendment, by
the Company and each Union or, in the case of a waiver, by the party against
whom the waiver is to be effective; provided that no amendment to or waiver of
an Express Agreement will be effective against a person entitled to enforce
such Express Agreement unless agreed to in writing by such person, and
provided, further, that after the adoption of the Shareholder Vote Matters by
the stockholders of the Company, no such amendment or waiver will, without the
further approval of such stockholders if and to the extent such approval is
required by the DGCL, alter or change (i) the amount or kind of consideration
to be received in connection with the Recapitalization, (ii) any term of the
Restated Certificate or (iii) any of the terms or conditions of the Plan of
Recapitalization if such alteration or change would materially adversely affect
the holders of any shares of capital stock of the Company, and (b) no failure
or delay by any party in exercising any right, power or privilege under the
Plan of Recapitalization will operate as a waiver thereof nor will any single
or partial exercise thereof preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. The rights and remedies
provided in the Plan of Recapitalization will be cumulative and, except as set
forth in the Plan of Recapitalization, not exclusive of any rights or remedies
provided by law.
 
 Fees and Expenses; Indemnification
   
  Pursuant to the Plan of Recapitalization, except as agreed by the Company and
the Unions in writing or as set forth below, all fees, costs and expenses
incurred in connection with the Plan of Recapitalization will be paid by the
party incurring such fee, cost or expense. The Company and the Unions agreed
that the fees, costs and expenses of the Deadlock Firm and American Appraisal
will be paid by the Company. The Company and the Unions agreed that the fees of
the Company's principal financial and legal advisors to be incurred by the
Company in connection with the transactions contemplated by the Plan of
Recapitalization (other than in connection with the Offering), will not exceed
$25 million. In addition, the Company has agreed to pay the following fees: (i)
up to $4.15 million in fees and expenses payable to counsel, investment banking
firms, experts, consultants or others relating to the structuring and
establishment of the ESOPs or otherwise benefitting the Company as part of the
Recapitalization, (ii) out-of-pocket expenses and fees paid, payable or
reimbursable to others by or pursuant to agreements with and among either or
both of the Unions (the "Coalition Fees"), subject to the following: (A) prior
to the Effective Time, the Company shall pay up to $7 million to or at the
direction of ALPA and up to $3 million to or at the direction of the IAM in
respect of Coalition Fees, which will represent payment for bona fide services
directly related to the transactions contemplated by the Plan of
Recapitalization since January 1, 1993 and will not exceed the aggregate time
or other customary charges together with disbursement costs of such firms since
such date for services of this type and (B) at the Effective Time the Company
will pay the balance of the Coalition Fees, subject to an overall limit of $45
million (including the amounts set forth in clause (A)), of which $31.5 million
is to be paid to or at the direction of ALPA and $13.5 million is to be paid to
or at the direction of the IAM and (iii) the fees of an executive search firm
and related executive expenses, in the event the Company and the Unions
determine to retain an executive search firm.     
 
  The Plan of Recapitalization provides that upon the occurrence of a
Triggering Event (as defined below), the Company will promptly pay to or at the
direction of the Unions any amounts the Company would otherwise have been
required to pay pursuant to the last sentence of the previous paragraph had the
Effective Time occurred at the time of the occurrence of such Triggering Event.
Such amounts would be exclusive of any amounts paid or payable pursuant to
indemnification or contribution arrangements. "Triggering Event" means the
occurrence of any of the following: (i)(A) following the public announcement of
a proposal for an Acquisition, either the stockholders of the Company do not
approve the Shareholder Vote Matters at the Meeting or (B) the Board withdraws
or modifies in a manner materially adverse to ALPA and the IAM its approval or
recommendation of the Recapitalization or the Shareholder Vote Matters or
recommends, or fails to recommend against, another Acquisition, (ii) subsequent
to the stockholder or Board action referred
 
                                       86
<PAGE>
 
   
to in clause (i) above, the Plan of Recapitalization will be terminated (1) by
the Company or either Union because the Stockholders of the Company fails to
approve the Shareholder Vote Matters, (2) by the Company because the Board
withdraws or modifies in a manner adverse to either Union its approval or
recommendation of the Recapitalization or recommends another Acquisition or
resolves to do any of the foregoing or (3) by either Union if the Board
withdraws or modifies in a manner materially adverse to such Union its approval
or recommendation of the Plan of Recapitalization or the Shareholder Vote
Matters, or recommends, or fails to recommend against, another acquisition and
(iii) within 12 months of the termination of the Plan of Recapitalization in
accordance with clause (ii) above, an Acquisition is consummated.     
 
  Pursuant to the Plan of Recapitalization, the Company agreed, subject to
certain exceptions, to indemnify the Unions, their controlling persons, and
their respective directors, trustees, officers, partners, affiliates, agents,
representatives, advisors and employees (a "Union Indemnified Person") against
and hold each Union Indemnified Person harmless from any and all liabilities,
losses, claims, damages, actions, proceedings, investigations or threats
thereof, including expenses (which will include reasonable attorneys' fees,
disbursements and other charges) incurred in connection with the defense
thereof, based upon, relating to or arising out of the execution, delivery or
performance of the Plan of Recapitalization or the transactions contemplated
thereby. All rights to indemnification existing in favor of the present or
former directors, officers, employees, fiduciaries and agents of the Company or
any of its subsidiaries (collectively, the "Company Indemnified Persons") as
provided in the Company's Restated Certificate of Incorporation or Bylaws or
other agreements or arrangements, or articles of incorporation or by-laws (or
similar documents) or other agreements or arrangements of any subsidiary as in
effect as of the date of the Plan of Recapitalization with respect to matters
occurring at or prior to the Effective Time will survive the Effective Time and
will continue in full force and effect. In addition, the Company will provide
for a period of not less than six years following the Effective Time, for
directors' and officers' liability insurance for the benefit of directors and
officers of the Company immediately prior to the Effective Time with respect to
matters occurring at or prior to the Effective Time by electing, in its sole
discretion, one of the two alternatives set forth below (which election will be
reported to the Unions prior to the Effective Time): (i) maintain for a period
of not less than six years following the Effective Time, the current policies
of directors' and officers' liability insurance with respect to matters
occurring at or prior to the Effective Time, provided that in satisfying its
obligation under this clause (i), the Company will not be obligated to pay
premiums in excess of 150% of the amount per annum the Company paid for the
policy year ending during calendar year 1994, which amount has been disclosed
to the Unions or (ii) purchase, prior to the Effective Time, run-off coverage
for the benefit of directors and officers of the Company immediately prior to
the Effective Time for matters occurring at or prior to the Effective Time,
which coverage will provide for a separate insurance pool for such directors
and officers of at least $75 million in coverage, provided that in satisfying
the obligations under this clause (ii), the Company will not pay in excess of
an amount set forth in a letter previously delivered by the Company to counsel
to the Unions. The Company will also maintain for a period of not less than six
years following the Effective Time, the current fiduciaries' liability
insurance with respect to matters occurring at or prior to the Effective Time.
   
  In connection with execution of the Plan of Recapitalization, the Company
entered into a letter agreement (the "Indemnity Letter Agreement") with ALPA
and the IAM relating to a claim against the IAM by a former financial advisor
(the "Former Advisor") against the IAM (the "Claims") for compensation in the
event of the occurrence of the Effective Time. The Claims include to the
following: (i) the Former Advisor's claim for compensation based on an
engagement letter between a corporation on behalf of the Former Advisor, on the
one hand, and the IAM and United Employee Acquisition Corp. ("UEAC"), on the
other hand, dated as of January 1, 1990, as amended by letter dated June 21,
1990 (collectively, the "Engagement Letter"), (ii) claims relating to services
performed by the Former Advisor pursuant to the Engagement Letter, and (iii)
claims based on any theory of compensation liability relating to facts alleged
to have existed at the time the Engagement Letter was entered into (or
subsequent performance of services originating from or based on such alleged
facts) and relating to services of the same nature and type as contemplated by
the Engagement Letter. The Engagement Letter provided for the payment to the
Former     
 
                                       87
<PAGE>
 
Advisor of a fee in the amount of $11 million, contingent upon the occurrence
of specified circumstances related to the Agreement and Plan of Merger, between
the Company and UEAC, dated as of April 9, 1990 ("1990 Merger Agreement"),
which $11 million fee was not paid as a result of a failure of the transactions
set forth in the 1990 Merger Agreement to occur.
 
  Pursuant to the Indemnity Letter Agreement, the Company has agreed to
indemnify the IAM against the Claims in accordance with the indemnification
provisions set forth in the Plan of Recapitalization described above, subject
to the terms and conditions set forth in the Indemnity Letter Agreement. The
Company's obligation to indemnify the IAM with respect to the Claims is limited
to $5.5 million prior to the Effective Time, subject to increase to a maximum
of $11 million (including the payment or reimbursement of IAM attorney's fees
and disbursements) if the Effective Time occurs. The Company's obligations
under the Indemnity Letter Agreement will be reduced by the amount recoverable
under any insurance policy, fidelity or indemnity bond issued to or for the
benefit of the IAM that may provide insurance or indemnity coverage against any
threatened or asserted claim by the Former Advisor against the IAM.
 
 Parties in Interest
   
  The Plan of Recapitalization will be binding upon and, other than the
provisions relating to fees, expenses and indemnification, inure solely to the
benefit of the parties thereto, and, except for the Express Agreements, nothing
in the Plan of Recapitalization, express or implied, is intended to confer upon
any other person any rights, benefits or remedies. With respect to the Express
Agreements, the agreements set forth below are for the benefit of, and may be
enforced by, the following parties: (i) the right to receive the
Recapitalization Consideration, the prohibition against nomination of Public
Directors by ALPA and the IAM and their obligation to use their best efforts to
fill Independent Directors vacancies: the holders of New Shares; (ii) treatment
of Options: holders of Options; (iii) treatment of Convertible Company
Securities: holders of Company Convertible Securities; (iv) resignation of
existing officers and directors prior to the Effective Time and the Company's
and United's obligations under their employee and director benefit plans,
agreements, policies and arrangements: officers and directors of the Company
prior to the Effective Time; (v) establishment by the Company of appropriate
employment terms for the Salaried and Management Employees: the ESOP Trustee;
(vi) the Greenwald Agreement: Mr. Greenwald; (vii) payment of fees and expenses
and indemnification of the Union Indemnified Persons: the Union Indemnified
Persons; and (viii) indemnification of Company Indemnified Persons: Company
Indemnified Persons.     
 
 Specific Performance
   
  Prior to the Effective Time or the termination of the Plan of
Recapitalization, the Company and each of the Unions agreed that in the event a
Willful Breach is established by a court of competent jurisdiction, the other
parties thereto will be entitled to specific performance of the terms thereof
that were the subject of such Willful Breach. However, in no event will such
remedy of specific performance in any way extend or modify the Outside
Termination Time. No other remedy will be available prior to the Effective Time
or the termination of the Plan of Recapitalization except that the remedy of
damages will be available if such remedy (including the amount of damages)
would be available after termination as described above under "--Termination."
    
ESTABLISHMENT OF ESOPS
       
       
       
 General
       
       
   
  As described under "--Terms and Conditions," preferred stock representing
approximately 55% of the voting and equity interests in the Company will be
delivered to employees through the ESOPs. As explained below, the ESOPs will be
comprised of three components, and the voting and equity interests to be
delivered pursuant to the ESOPs will be represented by five separate classes of
stock.     
       
                                       88
<PAGE>
 
   
  The three components which will comprise the ESOPs are (i) the "Leveraged
ESOP," which is a component of a tax-qualified employee stock ownership plan,
(ii) the "Non-Leveraged Qualified ESOP," which is also a component of a tax-
qualified employee stock ownership plan, and (iii) the "Supplemental ESOP,"
which is not a tax-qualified plan. The three components are needed in order to
deliver the agreed-upon shares to employees in a manner which utilizes the tax
incentives available to tax-qualified employee stock ownership plans to the
greatest degree reasonably possible, but without violating certain limitations
imposed by the Internal Revenue Code. Accordingly, to the extent reasonably
possible, shares are to be delivered to employees through the Leveraged ESOP.
To the extent that shares cannot be delivered through the Leveraged ESOP, they
will be delivered through the Non-Leveraged Qualified ESOP, and to the extent
they cannot be delivered through the Non-Leveraged Qualified ESOP, they will
be delivered through the Supplemental ESOP. Accordingly, the only employees
participating in the Supplemental ESOP are those employees who are unable to
receive, by virtue of the Internal Revenue Code limitations described above,
their full entitlement to shares under the Leveraged ESOP. Although the final
determination of which employees will participate in the Supplemental ESOP can
be made only when various factors, such as individual compensation, become
known, the Company expects that the only employees participating in the
Supplemental ESOP will be those Salaried and Management Employees with
compensation in excess of $150,000, a relatively small number of IAM members
and management and salaried employees who (as allowed by certain plans of the
Company) elect a relatively large reduction in their compensation in exchange
for child care and medical reimbursement payments, and a significant
percentage of ALPA members.     
   
  The five classes of stock which will represent the voting and equity
interests of employees are (1) the Class 1 ESOP Convertible Preferred Stock,
which will be issued in seven separate sales (the "ESOP Tranches") to the ESOP
Trustee under the Leveraged ESOP, (ii) the Class 2 ESOP Convertible Preferred
Stock, some of which will be issued to the ESOP Trustee under the Non-
Leveraged Qualified ESOP and some of which will be represented by "Book-Entry
Shares" (as defined below) credited to employees under the Supplemental ESOP,
and (iii) three classes of voting preferred stock (the Class P ESOP Voting
Preferred Stock, the Class M ESOP Voting Preferred Stock, and the Class S ESOP
Voting Preferred Stock. Collectively, the Class 1 and 2 ESOP Convertible
Preferred Stock are referred to as the "ESOP Preferred Stock," and
collectively, the three classes of voting preferred stock are referred to as
the "Voting Preferred Stock."     
   
  The equity interests of employees will be primarily represented by the Class
1 and Class 2 ESOP Preferred Stock. Each share of these two classes is
initially convertible into one New Share. The primary difference between the
Class 1 and the Class 2 ESOP Convertible Preferred Stock is that only the
Class 1 ESOP Convertible Preferred Stock carries a fixed dividend. The fixed
dividend exists in order to allow the delivery through the Leveraged ESOP of
the greatest number of shares reasonably possible, consistent with the
limitations of the Internal Revenue Code. An advantage provided for dividends
by the Internal Revenue Code exists only for the Leveraged ESOP, and for that
reason the Class 1 ESOP Convertible Preferred Stock will be sold only to the
Leveraged ESOP.     
   
  The voting interests of employees will be represented by the three classes
of ESOP Voting Preferred Stock. Each such share is convertible into one ten-
thousandth of a New Share. The Class 1 and Class 2 ESOP Preferred Stock is
non-voting.     
   
  The voting and equity interests of employees will be delivered through the
five separate classes of shares described above in order to satisfy two
purposes; (i) preservation of the agreed-upon distribution of voting power
among the ALPA, IAM and salaried and management employees, and (ii) ensuring
that the loan which will be used to purchase the Class 1 ESOP Convertible
Preferred Stock will satisfy a limitation of the Internal Revenue Code which
requires that shares purchased with a loan be consistently allocated among
employees. Sales of the Class 1 ESOP Convertible Preferred Stock to the
Leveraged ESOP will be made in seven ESOP Tranches. The first ESOP Tranche
will be sold to the ESOP Trustee at the Effective Time. The next five tranches
will be sold on the first day of the thirteenth month following the Effective
Time (or, if earlier, September 1, 1995), and on the four following
anniversaries of such date. The final ESOP Tranche will be sold on January 1,
2000. Each ESOP Tranche will be purchased by the ESOP Trustee using the
proceeds of     

                                      89
<PAGE>
 
   
a loan entered into specifically for the purchase of such ESOP Tranche. The
shares to be purchased in each of the first six ESOP Tranches shall generally
equal the sum of (i) the shares of Class 1 ESOP Convertible Preferred Stock
scheduled to be allocated to the accounts of participants in the Leveraged ESOP
for the year in which such ESOP Tranche is sold, plus (ii) the number of shares
of Class 1 ESOP Convertible Preferred Stock equal in value to the aggregate
dividends payable on the shares purchased with the ESOP Tranche after the end
of the year the ESOP Tranche is purchased. The final ESOP Tranche will not
include the shares described in (ii), above, however. The purpose of selling
shares to the ESOP in tranches is to attempt to take advantage of increases in
the price at which it is projected that the ESOP Convertible Preferred Stock
can be sold to the ESOP Trustee in the years following the Effective Time. The
projected price increases are based upon projected increases in the value of
the New Shares in the years following the Effective Time. THERE CAN BE NO
ASSURANCE THAT THE PROJECTED INCREASES IN THE PRICE OF THE NEW SHARES WILL
OCCUR. Therefore, there can be no assurance that the projected increases in the
price at which the Class 1 ESOP Convertible Preferred Stock can be sold to the
ESOP Trustee will occur.     
   
  A trust established pursuant to the leveraged ESOP will, as of the Effective
Time and over the following 69 months, through the seven ESOP Tranches, acquire
shares of Class 1 ESOP Preferred Stock, and the Company will be obligated to
issue (either through issuance to the Non-Leveraged Qualified ESOP or through
the crediting of Book-Entry Shares) shares of Class 2 ESOP Preferred Stock,
which are convertible, in the aggregate, into New Shares representing
(initially) approximately 55% of the Company, on a fully-diluted basis. (The
shares of Class 2 ESOP Preferred Stock represented by Book-Entry Shares will
not actually be issued until termination of employment, however.) ALPA has the
right to elect at any time on or before the Effective Time that the
Supplemental ESOP be maintained by the actual issuance of Class 2 ESOP
Preferred Stock to a non qualified trust established under the Supplemental
ESOP. As of the Effective Time, there will also be issued to the ESOP Trustee
shares of the three classes of Voting Preferred Stock (the "Voting Preferred
Stock") the outstanding shares of which will represent (initially)
approximately 55% of the voting power of all of the voting stock of the
Company. The ESOP Preferred Stock and Voting Preferred Stock held by the ESOP
will be allocated to the accounts of employees over the 69-month (72-month for
IAM members) period following the Effective Time. Under certain circumstances
described below under "--Additional Shares," the equity and voting interests
represented by the ESOP Preferred Stock and the Voting Preferred Stock can be
increased to up to a maximum of 63%.     
   
  Generally speaking, New Shares will be distributed to an employee pursuant to
the ESOPs after termination of employment; the New Shares so distributed will
be issued upon conversion of the ESOP Preferred Stock and Voting Preferred
Stock allocated to accounts of such employee in the ESOPs. Prior to the Sunset,
the percentage of the vote controlled by the shares of Voting Preferred Stock
held by the ESOP is unaffected by distributions to employees. See "--Revised
Governance Structure--Sunset" and "DESCRIPTION OF SECURITIES--The Voting
Preferred Stock--Voting Rights." Because of certain limitations imposed by the
Internal Revenue Code, there are several component plans included in the ESOP
program.     
   
  State Street, with the consent of the participating unions, has been retained
to act as the ESOP Trustee. The ESOP Trustee retained Houlihan Lokey as an
independent financial adviser. The ESOP Trustee has entered into an agreement
to purchase the ESOP Preferred Stock at the Effective Time on the terms
described below under "--Sales of ESOP Preferred Stock." The obligations of the
ESOP Trustee are subject to a number of conditions, including the receipt of an
opinion from Houlihan Lokey that, as of the Effective Time (and, with respect
to each ESOP Tranche after the Effective Time, at the time of each such
purchase), the applicable transaction is fair from a financial point of view to
the ESOP participants, the amount to be paid by the ESOP Trustee for the ESOP
Preferred Stock does not exceed the fair market value thereof and the
conversion of the ESOP Preferred Stock is reasonable. In addition, the
obligations of the ESOP Trustee are subject to the determination by the ESOP
Trustee that, as of the Effective Time (and, with respect to each ESOP Tranche
after the Effective Time, at the time of each such purchase), the purchase of
the ESOP Preferred Stock is prudent and in the best interests of ESOP
participants.     
 
                                       90
<PAGE>
 
   
 Sales of ESOP Preferred Stock     
   
  At the Effective Time and over the subsequent 69 months, the Company will
sell, in the seven ESOP Tranches, an aggregate of approximately 14,000,000
(subject to increase as described below, see "--Additional Shares") shares of
Class 1 ESOP Convertible Preferred Stock to a trust established pursuant to the
ESOPs.     
   
  Leveraged ESOP. 1,899,059 shares (subject to adjustment if agreed to by the
Company and the Unions) of Class 1 ESOP Convertible Preferred Stock shall be
sold as of the Effective Time in the first ESOP Tranche to a trust (the
"Qualified Trust") established under a tax-qualified employee stock ownership
plan (the "Qualified ESOP"), and additional shares of Class 1 ESOP Convertible
Preferred Stock will be sold to the qualified Trust in subsequent ESOP
Tranches. Such shares will be sold to the Leveraged ESOP which constitutes a
component of the Qualified ESOP. The aggregate number of shares sold will be
the highest number possible consistent with certain limitations of the Internal
Revenue Code, and is expected to be approximately 14,000,000. The Qualified
Trust will purchase the Class 1 ESOP Preferred Stock with a combination of cash
and a promissory note issued at the time of sale of each ESOP Tranche. The cash
will be equal to the aggregate par value of the Class 1 ESOP Convertible
Preferred Stock ($.01 per share) sold to the Qualified Trust. (The Company will
contribute such cash as a tax-deductible contribution to the Leveraged ESOP at
the time of the sale of each ESOP Tranche.) The balance of the purchase price
for each ESOP Tranche will be paid by a promissory note issued to the Company
by the ESOP Trustee in its capacity as trustee of the Qualified Trust.     
   
  Subject to certain terms and conditions set forth in the ESOP Stock Purchase
Agreement, including a condition that the Trustee will have made a good faith
determination that the purchase of Class 1 ESOP Preferred Stock is prudent and
in the best interests of the ESOP participants, the ESOP Trustee is obligated
to purchase the ESOP Preferred Stock for the first ESOP Tranche at a price per
share equal to [1.38 times the average closing price as of the Effective Time,
which average closing price shall be computed as the greater of the value of a
New Share at the Effective Time or 98% of two times the difference of the
average closing price of the Old Shares in the five trading days prior to the
Effective Time, less the value of the Recapitalization Consideration (other
than New Shares) issued with respect to an Old Share at the Effective Time. The
price for the subsequent ESOP Tranches will be as agreed upon between the
Company and the ESOP Trustee.     
   
  Federal law requires that the price paid by the ESOP Trustee for the Class 1
ESOP Preferred Stock cannot exceed its fair market value, and that the
conversion premium (the amount by which the price paid for the Class 1 ESOP
Convertible Preferred Stock exceeds the price of the New Shares as of the
Effective Time) must be reasonable. There can be no assurance as to the method
by which such an appropriate price may be developed for the subsequent ESOP
Tranches, including, without limitation, the appropriate base value for the New
Shares or the appropriate conversion premium. See "--Terms and Conditions--
Purchase of ESOP Preferred Stock."     
   
  The shares of Class 1 ESOP Preferred Stock purchased by the Qualified Trust
under the Leveraged ESOP in each ESOP Tranche will initially be held in a
suspense account and not allocated to the accounts of employees. The Company
will retain a security interest in the shares held in the suspense account. The
promissory notes will be repaid by the ESOP Trustee using cash received from
dividends paid on the Class 1 ESOP Preferred Stock and contributions to the
Qualified Trust to be made by the Company; the ESOP Trustee will be obligated
to use the dividends and Company contributions to repay the promissory notes.
It is expected that the entire amount of the Company contributions and the
dividends used by the ESOP Trustee to repay the promissory notes will be
deductible by the Company for Federal income tax purposes, regardless of the
portion used to pay interest and the portion used to pay principal. The Company
will recognize income equal to the interest paid on the promissory notes.
Accordingly, the net result of the contributions, dividends and promissory note
payments is that the Company expects to receive net tax deductions for Federal
income tax purposes equal to the principal amount of the promissory notes.     
 
 
                                       91
<PAGE>
 
   
  It is anticipated that the principal of the note for the first ESOP Tranche
will be paid in seven annual payments. The first annual payment will be for the
period commencing on the Effective Time and ending December 31, 1994, the
second through sixth payments will be for the twelve-month periods ending on
each December 31 from 1995 through 1999, and the final payment will be for the
period from January 1, 2000 until the end of the 69th month after the Effective
Time. (The 69-month period corresponds to the period of system-wide wage
reductions for ALPA members, and roughly corresponds to the 72-month period of
base wage reductions for IAM Members.) The notes for subsequent ESOP Tranches
will be of shorter duration, so that the final payment on each note will be due
on approximately the 69th month after the Effective Time.     
   
  Each calendar year (corresponding to the principal payments), shares of Class
1 ESOP Preferred Stock will be released from the suspense account, and the
Company's security interest in the shares so released will terminate. The
shares released for any year will be a fraction of the shares originally
purchased. It is anticipated that after taking separate ESOP Tranches into
account, the total number of shares of Class 1 ESOP Preferred Stock will be
released from the suspense account on a level annual fashion over 69 months,
taking into account the partial periods in 1994 and 2000.     
   
  When the shares are released from the suspense account as a result of any
principal payment, they remain in the Qualified Trust but are allocated to
individual accounts of employees established under the Leveraged ESOP. The
Class 1 ESOP Preferred Stock will be allocated to the accounts of employees
such that the shares so allocated when added to the shares (and Book-Entry
Shares) allocated under the Non-Leveraged Qualified ESOP and the Supplemental
ESOP (see "--Non-Qualified ESOP" below), will equal 46.23% for the employees
who are members of ALPA, 37.13% for employees who are members of the IAM, and
16.64% for Salaried and Management Employees (the "Agreed Percentages"). For
the shares released from the suspense account in respect of 1994, allocations
within each of these employee groups will be proportional to the compensation
(subject to certain tax limits) of all of the participants within that group,
except that for the participants who are members of the IAM, the shares will be
allocated in proportion to the amount of each individual employee's wage
investment. However, for subsequent years, shares equal in value to the
dividends paid on shares previously allocated to the accounts of employees will
first be allocated from the released shares to the accounts of such employees.
The remaining shares released from the suspense account in respect of that year
will be allocated to individual employees based upon their relative
compensation (or, in the case of IAM members, their relative wage investment).
    
   
  Non-Qualified ESOP. Because of certain limitations imposed by the Internal
Revenue Code, the Qualified Trust will not purchase shares representing the
entire equity interest (initially 55%) represented by the ESOP Preferred Stock.
Accordingly, based on certain elections made by ALPA, the Company will allocate
"phantom" shares of Class 2 ESOP Convertible Preferred Stock (the "Book-Entry
Shares") under the Supplemental ESOP. Except as provided below, these Book-
Entry Shares allocated to a participant will not in fact be issued by the
Company. Instead, the participant will have the same rights as a general
creditor of the Company with respect to amounts allocated to such participant
under the Supplemental ESOP. The number of shares of Class 2 ESOP Convertible
Preferred Stock will be equal to 17,675,345, less the number of shares of Class
1 ESOP Preferred Stock sold to the Qualified ESOP. It is anticipated that
almost all ESOP Stock reserved for allocation to IAM members will be allocated
under the Leveraged ESOP. ALPA has the right to elect at any time, before or
after the Effective Time, that the Supplemental ESOP be maintained by the
actual issuance of Class 2 ESOP Convertible Preferred Stock to a non-qualified
trust (the "Non-Qualified Trust") established under the Supplemental ESOP.     
   
  Each year, as a portion of the shares of Class 1 ESOP Convertible Preferred
Stock are released from the suspense account under the Leveraged ESOP, the same
proportion of the Book-Entry Shares of Class 2 ESOP Convertible Preferred Stock
will be allocated as described below. In other words, it is anticipated that
the Class 2 ESOP Convertible Preferred Stock will be allocated over the same 69
months that the Class 1 ESOP Convertible Preferred is allocated. To the extent
permissible under the Internal Revenue Code, the shares of Class 2 ESOP
Convertible Preferred Stock will be issued by the Company and transferred to
the Qualified Trust for allocation to employees' accounts under Non-Leveraged
Qualified ESOP, which is a component of     
 
                                       92
<PAGE>
 
   
the Qualified ESOP. The Book-Entry Shares that cannot be transferred to the
Qualified Trust will be credited to the accounts of employees in the
Supplemental ESOP (and if ALPA elects that the Non-Qualified Trust will hold
Class 2 ESOP Convertible Preferred Stock, will be deposited therein). Unlike
the Qualified ESOP, the Company will be liable for the benefits of employees
under the Supplemental ESOP. Hypothetical dividends will be credited to such
Book Entry Shares as if they were actual shares of Class 2 ESOP Convertible
Preferred Stock.     
   
  In the aggregate, the shares allocated under the Leveraged ESOP, the Non-
Leveraged Qualified ESOP, and the Supplemental ESOP will equal the Agreed
Percentages.     
   
  Allocation of Voting Preferred Stock. The ESOP Preferred Stock is nonvoting
(except as may be otherwise required by law). The Voting Preferred Stock was
established in order to allocate voting power to the respective employee groups
in proportion to the agreed upon allocation and in a manner which was
consistent with applicable law. When shares of Class 1 ESOP Convertible
Preferred Stock are released from the suspense account and allocated to
accounts of employees, and when shares (or Book-Entry Shares) of Class 2 ESOP
Convertible Preferred Stock are allocated under the Qualified ESOP or the
Supplemental ESOP, the corresponding number of shares of the appropriate class
of Voting Preferred Stock will be issued by the Company and contributed to the
Non-Leveraged Qualified ESOP (or, to the extent limitations of the Internal
Revenue Code require, to the Non-Qualified Trust established under the
Supplemental ESOP). However, the additional issuance of shares of Voting
Preferred Stock will not affect the percentage of voting power of the Company
as a whole controlled in the aggregate by the Voting Preferred Stock. The ESOP
Trustee is obligated to vote as instructed by the participants to whom the
Voting Preferred Stock has been allocated, and the shares which are allocated
command the entire voting power of each class of Voting Preferred Stock.
Accordingly, the contribution of Voting Preferred Stock to the ESOPs and the
allocation of such stock to participants subsequent to the Effective Time does
not affect the aggregate vote commanded by the Voting Preferred Stock, but it
does affect the allocation of voting power among the individual participants.
ALPA has made an agreed-upon election to require that the ESOP Trustee follow
only the directions of the active employees who are ALPA members in voting the
Class P Voting Preferred Stock. The effect of this election, if implemented, is
that the shares of Class P Voting Preferred Stock allocated to former employees
who were ALPA members will be voted by the ESOP Trustee as directed by the
active employees who are ALPA members. The Company is not required to implement
ALPA's election if either (i) the Company is unable reasonably to conclude that
implementation of such election would be legal, or (ii) the Company reasonably
concludes that implementation of such election would expose the Company to a
risk of any material liability. If the Company does not implement ALPA's
election, the Company is required to cooperate with ALPA to determine if the
objective of the election can be accomplished by other means. Such other means
may, for example, include non-material changes to the ESOPs, but the Company is
not required to implement such other means if the objectives of the Plan of
Recapitalization would be thwarted, or if such other means would impose costs
on the Company in excess of $100,000.     
   
  Distributions. Employees will become entitled to distribution of shares upon
termination of employment but can elect to defer distribution until age 70 1/2.
Employees will become entitled to transfer shares from the Leveraged ESOP and
the Non-Leveraged Qualified ESOP to other Company plans prior to termination of
employment upon attainment of age 55 with at least 10 years of participation in
the ESOP. (Because of this requirement of 10 years of participation, the first
such distributions will not be made until at least 10 years after the Effective
Time.) The ability to so transfer prior to termination of employment is
required under the Internal Revenue Code for the purpose of allowing employees
to diversify their investments. Up to 25% of an employee's account may be
diversified at age 55, and an additional 25% may be diversified at age 60. The
diversification distribution for an employee will be made by transferring the
appropriate amount to the tax-qualified 401(k) plan sponsored by the Company in
which the employee participates.     
   
  Prior to any distribution, the shares of ESOP Preferred Stock (and the
corresponding shares of Voting Preferred Stock) allocated to the employee
entitled to the distribution will be converted into New Shares.     
 
                                       93
<PAGE>
 
   
The employee may choose to receive the distribution in the form of the New
Shares issued upon conversion or cash, and except for the diversification
distributions described above, the employee may elect to receive the
distribution in a lump sum or annual installments over five years. Employees
who remain employed after age 70 1/2 shall receive annually the minimum
payments required by the Internal Revenue Code. If the employee elects to
receive cash, the ESOP Trustee will sell the New Shares, and pay the net
proceeds of the sale to the employee. Book-Entry Shares allocated to the
Participant under the Supplemental ESOP will, at the employee's election,
either be distributed in the form of New Shares issued by the Company or cash
equal to the net proceeds from the sale of such New Shares.     
 
  Each share of the Voting Preferred Stock is convertible into one ten-
thousandth of a New Share. Accordingly, when an ESOP participant becomes
entitled to receive a distribution of the Voting Preferred Stock, such shares
will be converted to New Shares and distributed (either as cash or New Shares).
Notwithstanding the conversion of the Preferred Stock upon a distribution or
diversification transfer, however, the remaining shares of the Voting Preferred
Stock continue to command, in the aggregate, the same percentage vote. This
continues as long as the employee plans of the Company contain, in the
aggregate, shares representing the equivalent of at least 20% of the equity
interests in the Company. See "DESCRIPTION OF SECURITIES--The Voting Preferred
Stock--Voting Rights."
 
 Additional Shares
   
  If the Average Closing Price of the New Shares during the year following the
Effective Time exceeds $136 per share, additional shares of ESOP Preferred
Stock (the "Additional Shares") will be issued to the Qualified ESOP or will be
reserved for issuance or credited as Book-Entry Shares. The number of
Additional Shares will be calculated based in part upon the fully diluted
number of New Shares on the Measuring Date. On the Measuring Date, the fully
diluted number of New Shares (the "Fully Diluted New Shares") will be
determined as the sum of the Additional Shares and:     
 
    (i) the difference between (A) the number of New Shares outstanding on
  the Measuring Date and (B) the number of New Shares issued after the
  Effective Time other than upon the exercise, conversion or exchange of
  Options or the Company Convertible Securities,
 
    (ii) the number of New Shares issuable upon the conversion of the Series
  A Preferred Stock outstanding immediately prior to the Measuring Date,
 
    (iii) the number of New Shares issuable upon the exercise, conversion or
  exchange of other Convertible Securities outstanding immediately prior to
  the Measuring Date that have an exercise, conversion or exchange price that
  is equal to or less than the average market price of the Recapitalization
  Consideration issued in respect of one Old Share during the year ending on
  the Measuring Date (the "Old Share Equivalent Price") and
 
    (iv) the number of net New Shares that would have been issued if the
  Company issued New Shares in respect of all the Options outstanding
  immediately prior to the Measuring Date that have an exercise price that is
  less than the Old Share Equivalent Price and used the aggregate exercise
  price received to purchase Recapitalization Consideration on a pro rata
  basis in the open market at the Old Share Equivalent Price.
   
The number of Additional Shares will be determined as the excess of (a) the
product of the Fully Diluted New Shares and a fraction, the numerator of which
is the "Adjusted Percentage" and the denominator of which (expressed as a
percentage) is one (1) minus the "Adjusted Percentage" (the first two columns
of the table set forth below utilize selected samples from the table attached
to the Plan of Recapitalization from which the Adjusted Percentage will be
derived) over 17,675,375. (The foregoing calculation will not cause a reduction
of the number of shares of ESOP Preferred Stock then outstanding.) "Average
Closing Price" means the average of the product of the last sale market price
of the New Shares on each trading day during the year ending on the Measuring
Date and the number of New Shares into which one share of ESOP Preferred Stock
could be converted on such trading day. (Initially, each share of ESOP
Preferred Stock will be convertible into one New Share, subject to adjustment
for various reasons).

<PAGE>
 
   
  The following table illustrates the possible effect of increasing the Average
Closing Price on the number of Additional Shares issuable upon conversion of
the ESOP Preferred Stock and the Voting Preferred Stock. The illustration
assumes that the number of Fully Diluted New Shares on the Measuring Date is
32,140,206 (before any issuance or reservation of Additional Shares),
consisting of (x) an aggregate of 14,463,093 New Shares (1) issued in respect
of Old Shares outstanding at the Effective Time, (2) issuable upon the exercise
of the Options and (3) issuable upon the exercise of the Convertible
Securities, (y) 17,675,345 New Shares issuable upon conversion of the
17,675,345 shares of ESOP Preferred Stock and (z) 1,768 New Shares issuable
upon conversion of the 17,675,345 shares of Voting Preferred Stock.

</TABLE>
- --------
(1) A small portion of the Additional Shares may be issuable upon conversion of
    the Voting Preferred Stock, but the number of New Shares issuable in
    respect of the ESOP Preferred Stock would be adjusted so that the aggregate
    number of Additional Shares would not change as a result.
   
  The number of New Shares that will become outstanding may be higher or lower
than the number of Fully Diluted New Shares determined on the Measuring Date,
as described above, for a number of different reasons, including that a larger
or smaller number of Options and Convertible Company Securities may be
exercised and that the holders of the Options may not use the "cashless
exercise" feature thereof. The terms of the Options will permit the holders to
surrender to the Company a portion of the Options in lieu of paying the
exercise price thereof in cash and/or in lieu of paying withholding tax in
respect of such exercise in cash. The amount of the Options surrendered as a
substitution for payment of cash will be determined based upon the market price
of the Recapitalization Consideration on the date of exercise (i.e., the higher
the market price, the fewer number of shares surrendered in substitution for
cash). If such "cashless exercise" feature is used, the effect on the number of
New Shares that would be outstanding would be similar to the deemed repurchase
of New Shares (as part of the Recapitalization Consideration) by the Company
referred to in clause (iv) in the description of Fully Diluted New Shares,
above. Accordingly, the number of New Shares that become outstanding will vary
depending on the number of Options exercised, the extent to which the "cashless
exercise" feature is used and the market price on the date the "cashless
exercise" feature is used. However, if the holders of Options do not use the
"cashless exercise" feature, the cash received from the exercise of options
would be available to the Company, which would not be the case if the "cashless
exercise" feature were used. In addition, if the "cashless exercise" feature is
used, the market price of the Recapitalization Consideration on the date of
exercise will have an effect on the number of New Shares outstanding, since a
higher market price will cause fewer Options to be withheld for payment and a
lower market price will cause more Options to be withheld for payment.
Accordingly, there can be no assurance that the number of New Shares
outstanding after conversion of all the ESOP Preferred Stock (including the
Book-Entry Shares), will be as reflected in the table above.     
       
   
  The aggregate voting power commanded by the Voting Preferred Stock will be
increased automatically when the number of Additional Shares, if any, is
determined.

 Additional Contributions
   
  If the Company pays a dividend on New Shares while any portion of a
promissory note issued by the ESOP Trustee to purchase Class 1 ESOP Preferred
Stock remains outstanding, the Company will make an additional contribution in
cash to the ESOP. In general the additional contribution would equal the lesser
of (1) the dividend paid on each New Share times the number of New Shares into
which the shares of Class 1 ESOP Preferred Stock are convertible, or (2) the
fixed dividend payable on the Class 1 ESOP Preferred Stock. This calculation
will be made as if all Class 1 ESOP Preferred Stock had been issued at the
Effective Time. The additional contribution would be allocated to the accounts
of employees and not used to repay the promissory note.     
   
  The Supplemental ESOP contains provisions analogous to those in the preceding
paragraph with regard to Book-Entry Shares which have not yet been credited as
Class 2 ESOP Preferred Stock which has not yet been issued.     
   
  The fixed dividends on the Class 1 ESOP Preferred Stock will be used to repay
the promissory note, but any dividends received in excess of the fixed dividend
rate will be allocated to the accounts of employees and will not be used to
repay the promissory note.     
 
 Control Transactions
   
  In a Control Transaction (as defined below), participants are entitled, as
named fiduciaries under ERISA, to instruct the ESOP Trustee as to whether to
tender, sell, convert or otherwise dispose of shares allocated to their
accounts under the Qualified ESOP. Furthermore, in a Control Transaction each
employee (but not a former employee) who is a participant in the Qualified ESOP
may direct the ESOP Trustee whether to tender, sell, convert or otherwise
dispose of shares held in the suspense account under the Qualified Trust and
shares for which no instructions are received; the ESOP Trustee will tender
such shares in the proportion directed by such employees (except when ERISA (as
defined below) requires the ESOP Trustee to disregard such directions). A
"Control Transaction" is a tender or exchange offer, or other opportunity to
dispose of or convert shares of the Company (other than conversions pursuant to
distributions to be made under the ESOP), or any transaction or series of
related transactions whereby any person or group acquires control of the
Company or of all or substantially all or the assets of the Company and its
subsidiaries.     
   
  All shares of Class 1 and Class 2 ESOP Preferred Stock intended to be
transferred to the ESOPs in connection with future sales of the ESOP Tranches
will be transferred to the ESOPs prior to the Control Transaction (unless ALPA
specifies otherwise with respect to the Supplemental ESOP).     
 
  Shares held by the Supplemental ESOP will be tendered as directed by the
administrative committee thereunder.
   
  If a Control Transaction results in the sale or exchange of any shares held
by the ESOPs, and the proceeds of the sale are (or are used to acquire)
"appropriate securities," as defined below, then the ESOP and the promissory
notes under the Leveraged ESOP shall continue as if the Control Transaction had
not occurred. To the extent possible, the proceeds will be used to acquire
"appropriate securities." If "appropriate securities" cannot be obtained, then
the Company and the Unions will make appropriate arrangements reasonably
satisfactory to the Unions to protect the interests of the employees. It is not
the present intention of the Company and the Unions that such arrangements will
include the forgiveness of any portion of the promissory note. "Appropriate
securities" are shares of common stock (or preferred stock which converts into
common stock) that may be held as security for a loan to an employee stock
ownership plan under the applicable Internal Revenue Code requirements, and
that are issued by a public company having a Moody's senior long-term debt
rating at least as good as that of the Company and United.     
 
 Participation and Vesting
 
  Members of the ALPA employee group become participants in the ESOPs
immediately upon commencement of employment. IAM and Salaried and Management
Employees who are employed at the Effective Time will immediately become
participants in the ESOPs. All other members of the IAM employee group become
participants upon completing a probationary period of six months. All other
Salaried and
 
                                       96
<PAGE>
 
Management Employees become participants following a one-year waiting period.
All shares allocated to the accounts of employees under the ESOP are fully
vested.
 
 Federal Income Tax Matters
 
  The Qualified ESOP is intended to be qualified under Sections 401 and 501 of
the Internal Revenue Code, and the Leveraged ESOP is intended to be qualified
under Section 4975 of the Internal Revenue Code. The Company will apply to the
IRS for a determination letter to that effect. As a result of such
qualification, employer contributions to the Qualified ESOP (including
contributions or transfers of shares of Class 2 ESOP Preferred Stock to the
Non-Leveraged Qualified ESOP) are deductible for Federal income tax purposes,
but ESOP participants are not subject to Federal income tax on such
contributions or on income derived from such contributions until distributions
are made from the Qualified ESOP. At the time of distribution, certain
favorable income tax rules may apply to the determination of such participants'
Federal income tax liability with respect to such distribution.
 
  The Supplemental ESOP and Non-Qualified Trust do not constitute a tax-
qualified plan. The Company will not be entitled to a tax deduction until
benefits are paid to participants. Any income earned by the Non-Qualified
Trust, excluding dividends paid on Company securities, will be taxed to the
Company.
 
  It is expected that the dividends payable on the Class 1 ESOP Preferred Stock
will be deductible to the extent used to repay the promissory note issued by
the ESOP Trustee.
 
 Plan Administration
 
  The Qualified ESOP will be administered by a committee consisting of three
appointees of ALPA, two appointees of the IAM and one appointee of the Company;
the Supplemental ESOP will be administered by a committee consisting of three
members appointed by ALPA and one member appointed by the Company; provided
that if any IAM member is allocated shares under the Supplemental ESOP, then
two members appointed by the IAM shall, with respect to the IAM shares, join
the committee that administers the Supplemental ESOP. Deadlocks in votes of the
committee will be referred for decision to a neutral arbitrator. Except for
certain decisions concerning the management of the plan's assets, the member
appointed by the Company, the two members appointed by the IAM or a majority of
the members appointed by ALPA can require that any committee decision be
referred to a neutral arbitrator.
 
                             ELECTION OF DIRECTORS
 
NOMINEES FOR ELECTION AS PUBLIC DIRECTORS
 
  If the Recapitalization is approved, the new structure of the Board will be
established and four persons will be eligible for election as "Public
Directors". The fifth person to be a Public Director will be identified at or
prior to the Effective Time and will be appointed to the Board at the Effective
Time.
 
  Except where authority has been withheld by a stockholder, the enclosed proxy
will be voted for the election of the nominees named below for a term of one
year and until the successors are duly elected and qualified.
   
  Each nominee for Public Director (other than Mr. Greenwald) was previously
elected by the stockholders and has served continuously as a director for the
period succeeding the date of his or her election. In the event any one or more
of the named nominees shall become unable to serve before election, votes will
be cast pursuant to authority granted by the enclosed proxy for such person or
persons as may be designated in substitution for such nominees by the Board but
not for a greater number of persons than the nominees named herein. No person,
other than the directors of the Company acting solely in that capacity, is
responsible for the naming of the nominees.

(a) In the first quarter of 1994, United began recording certain air
    transportation price adjustments, which were previously recorded as
    commission expense, as adjustments to revenue. Operating revenues and
    certain operating statistics for periods prior to 1994 have been adjusted
    to conform with the current presentation.     
   
(b) The Pro Forma Statement of Consolidated Financial Position assumes the
    transaction occurred at March 31, 1994. Therefore, pro forma information at
    December 31, 1993 is not applicable.     
       
   
(c) Earnings were inadequate to cover both fixed charges and fixed charges and
    preferred stock dividends by $98 million in 1993, by $748 million in 1992
    and by $599 million in 1991. On a pro forma basis, earnings were inadequate
    to cover fixed charges by $109 million in 1993.     
   
(d) Earnings were inadequate to cover both fixed charges and fixed charges and
    preferred stock dividends by $118 million and $224 million for the three
    month periods ended March 31, 1994 and 1993, respectively. On a pro forma
    basis earnings were inadequate to cover fixed charges by $97 million for
    the three months ended March 31, 1994.     
       
       
   
(e) The loss from operations includes an ESOP accounting charge which is
    dependent on the fair market value of the ESOP Preferred Stock during the
    period. The pro forma amount is based on an assumed fair value of $120 per
    share. See note 4 to the Pro Forma Condensed Statement of Consolidated
    Operations for both the year ended December 31, 1993 and the three months
    ended March 31, 1994 for the effects of different fair value assumptions on
    the ESOP accounting charge.

(a) In the first quarter of 1994, United began recording certain air
    transportation price adjustments, which were previously recorded as
    commission expense, as adjustments to revenue. Historical operating
    revenue amounts and certain operating statistics for periods prior to 1994
    have been adjusted to conform with the current presentation.     
   
(b) The Pro Forma Statement of Consolidated Financial Position assumes the
    transaction occurred at March 31, 1994. Therefore, pro forma information at
    December 31, 1993 is not applicable.     
   
(c) Earnings were inadequate to cover fixed charges by $77 million in 1993, by
    $694 million in 1992 and by $604 million in 1991. On a pro forma basis,
    earnings were inadequate to cover fixed charges by $63 million in 1993.     
   
(d) Earnings were inadequate to cover fixed charges by $130 million and $211
    million for the three month periods ended March 31, 1994 and 1993,
    respectively. On a pro forma basis, earnings were inadequate to cover fixed
    charges by $102 million for the three months ended March 31, 1994.     
   
(e) The loss from operations includes an ESOP accounting charge which is
    dependent on the fair market value of the ESOP Preferred Stock during the
    period. The pro forma amount is based on an assumed fair value of $120 per
    share. See note 4 to the Pro Forma Condensed Statement of Consolidated
    Operations for both the year ended December 31, 1993 and the three months
    ended March 31, 1994 for the effects of different fair value assumptions
    on the ESOP accounting charge.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
       
   
  The following are the unaudited Pro Forma Financial Information for each of
the Company and United. These statements are based on an assumed purchase
price for the Class 1 ESOP Preferred Stock at the Effective Time of $120 per
share. The actual purchase price for the Class 1 ESOP Preferred Stock at the
Effective Time will be based on a market price-based formula. See "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Sales of ESOP Preferred Stock."
These sets of unaudited Pro Forma Financial Information do not purport to be
indicative of the results of operations or financial position that may be
obtained in the future or that would actually have been obtained had the
Recapitalization occurred on the dates indicated. In addition, there can be no
assurance as to the purchase price of the Class 1 ESOP Preferred Stock.     
       
                    
                 UAL CORPORATION AND SUBSIDIARY COMPANIES     
   
  The following unaudited Pro Forma Condensed Statements of Consolidated
Operations for the year ended December 31, 1993 and the three months ended
March 31, 1994, and the unaudited Pro Forma Condensed Statement of
Consolidated Financial Position as of March 31, 1994 for the Company and its
subsidiaries have been prepared to reflect the Recapitalization, including:
(i) the reclassification of Old Shares into New Shares and Redeemable
Preferred Stock, (ii) the Offerings of interests in the Public Preferred Stock
(as represented by Depositary Preferred Shares) and Debentures, (iii) the
exchange of Redeemable Preferred Stock for cash and proceeds from the
Offerings, (iv) the issuance of the first tranche of Class 1 ESOP Preferred
Stock to the ESOP Trustee in exchange for cash and a promissory note, (v) the
recognition of unearned ESOP Preferred Stock and the related additional
capital invested, (vi) the recognition of the employee stock ownership plan
accounting charge, (vii) the reduction of salaries and related costs for the
anticipated impact of the wage and benefit reduction and certain work rule
changes and (viii) the recognition of the anticipated benefits from the
agreement to sell the U.S. flight kitchens. The unaudited Pro Forma Condensed
Statements of Consolidated Operations were prepared as if the Recapitalization
had occurred on January 1, 1993. The unaudited Pro Forma Condensed Statement
of Consolidated Financial Position was prepared as if the Recapitalization
occurred on March 31, 1994.     
   
  The pro forma statements assume the Recapitalization is not accounted for as
an acquisition or merger and, accordingly, UAL's assets and liabilities have
not been revalued. The reclassification of Old Shares into New Shares results
in the elimination of the par value of the Old Shares and recognition of the
par value of the New Shares. The distribution of the cash to holders of Old
Shares is charged to additional capital invested and retained earnings.     
   
  The ESOPs are being accounted for in accordance with the American Institute
of Certified Public Accountants Statement of Position 93-6, "Employers'
Accounting for Employee Stock Ownership Plans" ("SOP"). For the Leveraged
ESOP, the Company will issue Class 1 ESOP Preferred Stock through seven ESOP
Tranches beginning at the Effective Time, thirteen months following the
Effective Time, annually thereafter for four years with a final ESOP Tranche
on January 1, 2000. As the shares are issued to the Leveraged ESOP, the
Company will report the issuance of shares as a credit to additional capital
invested based on the fair value of the stock when such issuance occurs and
report a corresponding charge to unearned ESOP Preferred Stock. As
consideration for the shares, the Company will receive from the ESOP Trustee a
series of promissory notes and cash. The notes will not be recorded in the
Company's Statement of Consolidated Financial Position and the related
interest income will also not be recorded in the Company's Statement of
Consolidated Operations. As shares of Class 1 ESOP Preferred Stock are earned
or committed to be released, an employee stock ownership plan accounting
charge will be recognized equal to the average fair value of the shares
committed to be released with a corresponding credit to unearned ESOP
Preferred Stock. Any differences between the fair value of the shares
committed to be released and the cost of the shares to the ESOP will be
charged or credited to additional capital invested. For the Non-Leveraged
Qualified ESOP and the Supplemental ESOP, the shares of Class 2 ESOP Preferred
Stock will be recorded as the shares are committed to be contributed to the
ESOP, with the offsetting entry to compensation expense.     
 
                                      105
<PAGE>
 
   
Compensation expense will be recorded based on the fair value of the shares
committed to be contributed to the ESOP, in accordance with the SOP.     
       
   
  The ESOP Preferred Stock is considered to be a common stock equivalent since
the shares cannot remain outstanding indefinitely and participants cannot
withdraw their shares from the plan. Under the SOP, when computing primary and
fully diluted earnings per share, only those shares committed to be released
are considered outstanding as common stock equivalents. Prospectively, as
dividends are paid by the Company to the ESOP, only dividends on allocated
shares will be recorded as a charge to equity. Since the Company controls the
use of the dividends on unallocated ESOP Preferred Stock, such dividends will
be recorded as compensation expense.     
   
  The unaudited Pro Forma Condensed Statements of Consolidated Operations
include the recurring charges and credits that are directly attributable to the
Recapitalization, such as the interest expense arising from the Debentures, the
effects of the wage and benefit reductions and certain work-rule changes
resulting from the employee investment, and the employee stock ownership plan
accounting charge. No adjustments have been made to the pro forma revenues and
expenses to reflect the results of structural changes in operations, such as
U2, that might have been made had the changes been consummated on the assumed
effective dates for presenting pro forma results.     
   
   The pro forma adjustments are based upon available information and upon
certain assumptions that the Company believes are reasonable. In addition, this
information should be read in conjunction with the Company's Annual Report on
Form 10-K for the year ended December 31, 1993, as amended, and the Company's
Quarterly Report on Form 10-Q for the quarter ended March 31, 1994, as amended,
which are included elsewhere in this Proxy Statement/Prospectus and which
include the Company's Consolidated Financial Statements and the related notes
thereto and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

                   FOR THE YEAR ENDED DECEMBER 31, 1993     
   
 (1) The Company entered into an agreement to sell its U.S. flight kitchens
     over a period of months beginning in December 1993 through June 1994 and
     an agreement to acquire catering services for a seven year period. This
     adjustment eliminates $28 million of sales revenues and $191 million of
     compensation costs recorded in 1993 relating to the U.S. flight kitchens
     that were sold and adds estimated incremental catering costs of $131
     million.     
   
 (2) To adjust compensation expense for the pro forma effect of the wage and
     benefit reductions and certain work-rule changes resulting from the
     employee investment that provide for wage and other compensation savings
     during the approximately six year period beginning at the Effective Time.
     The pro forma adjustment represents the estimated savings in the 12 months
     assuming that such savings had commenced at the beginning of the period.
     The pro forma adjustment does not include any savings related to U2.     
   
 (3) The following reconciles the labor cost savings included in the Pro Forma
     Condensed Statement of Consolidated Operations to the value of the
     employee investments included in the Company Analysis of employee
     investments for 1994 (see "SPECIAL FACTORS--Certain Company Analyses"):

</TABLE>
   
 (4) To record non-cash compensation for shares of ESOP Preferred Stock
     committed to be released to employees during the period based on the
     average fair value of such ESOP Preferred Stock. The average fair value of
     the ESOP Preferred Stock is based on two components: (1) the average fair
     value of the New Shares into which the ESOP Preferred Stock is convertible
     plus (2) a premium attributable to the dividend paying feature of the ESOP
     Preferred Stock. For purposes of the pro forma adjustment, the average
     fair value of the ESOP Preferred Stock was assumed to be the initial
     purchase price of $120. In future years, it is anticipated that the ESOP
     Preferred Stock price, for purposes of computing the employees stock
     ownership plan accounting charge, will be determined by an independent
     appraiser who will value both components. Additionally, in future years,
     the shares committed to be released that are used to satisfy the dividends
     payable on previously allocated shares will be charged to retained
     earnings rather than compensation expense.     
        
     The shares of the ESOP Preferred Stock committed to be released are a
     fraction of the original ESOP Preferred Stock shares. It is anticipated
     the shares will be released in a level fashion over the 69 months of the
     ESOP taking into account the partial periods in 1994 and 2000. This would
     result in approximately 3.07 million ESOP Preferred Stock shares
     committed to be released in each full calendar year. Shares released in a
     partial year would be pro rated.     
        
     Since future expense is dependent on the fair market value of the ESOP
     Preferred Stock, it is difficult to forecast and may vary significantly
     from the value in the pro forma adjustment. Changes in the price of a New
     Share directly affect the determination of the value of a share of ESOP
     Preferred Stock. In addition, if the average value of a New Share exceeds
     $136 during the first 12 months after the Effective

   Date, additional shares of ESOP Preferred Stock will be issued to the
   Qualified Trust or reserved for issuance to the Non-Qualified Plan to
   increase the ESOP's ownership from 55% up to a maximum of 63%. Future
   expense is also affected by the premium associated with the dividend
   paying feature which shrinks over time as the dividend paying period is
   reduced.     
       
   
   Following is a summary of the impact to the employee stock ownership plan
   accounting charge of a range of fair market values:

   *   Assumes a dividend premium of $32 per share.     
      
   **  To achieve the maximum increase in ownership, the price of a New Share
       must average at least $149.10 during the first 12 months after the
       Effective Date. If the average price of a New Share is less than or
       equal to $136, no additional shares of ESOP Preferred Stock will be
       issued.     
      
   *** The additional shares will be released in a level fashion over the 69
       months of the ESOP.     
      
   ****Represents the first year increase; subsequent increases are
       dependent on changes in the fair value of the ESOP Preferred Stock.
           
   
 (5) To record the interest expense on the Series A Debentures at an annual
     estimated interest rate of 9.0% and on the Series B Debentures at an
     annual estimated interest rate of 9.7%, and to record amortization of the
     underwriting discount. For purposes of the pro forma adjustment, the
     interest rates are based on the Initial Pricing. The actual rates will be
     reset prior to Closing and any upward reset is limited to an additional
     112.5 basis points. If the reset results in the actual rate being at the
     maximum interest rate, interest expense would increase by an additional $9
     million for the year. Further, if the Unions request prior to the
     Announcement Date that the Debentures contain a call provision, the actual
     rates may increase above the cap.     
        
     The underwriting agreements for the Offerings are expected to provide
     that if the Offerings are consummated, the interest rates may be adjusted
     to permit the Debentures to be sold at or closer to par, but if this is
     done, the principal amount of the Debentures will be reduced so that the
     interest payable will not exceed the stated maximum which was calculated
     based upon the interest rate cap. If the Offerings are not consummated,
     the interest rates are subject to the cap.     
   
 (6) To record foregone interest income due to the reduction in the Company's
     average investment balance resulting from the Recapitalization. The pro
     forma adjustment is based on the Company's average earnings rate during
     1993.     
 
                                      109
<PAGE>
 
   
 (7) To adjust the provision (credit) for income taxes to reflect the tax
     effect of changes to pretax income at the statutory rate in effect during
     1993. For purposes of the pro forma adjustments, the book and tax
     employee stock ownership plan compensation charge are assumed to be the
     same.     
   
 (8) If the Recapitalization is consummated, the Company expects to recognize
     nonrecurring charges of approximately $44 million relating to additional
     severance benefits for employees terminated as a result of the sale of
     the flight kitchens, up to $49.15 million of transaction fees and
     expenses incurred by ALPA, the IAM and certain advisors in connection
     with the structuring and establishment of the ESOPs, $30 million for the
     Company's transaction fees and expenses, $17 million of compensation
     expense relating to vesting the unvested restricted stock as a result of
     the change in control, $21 million of payments and benefits to Mr.
     Greenwald and officers who are retiring at the Effective Time, and $13
     million of compensation expense (based on an assumed Old Share price of
     approximately $131 at the Effective Time) relating to the vesting of
     unvested Options and the implementation of a feature that provides for
     cashless exercise of Options in the event of the Recapitalization. (The
     existing Option holders are only entitled to utilize the cashless
     exercise feature if the Recapitalization occurs. The pro forma financial
     information assumes all in-the-money Options are exercised at the
     Effective Time and, since the cashless exercise results in variable plan
     accounting, there is an initial nonrecurring charge for the cashless
     exercise feature but no ongoing impact; however, if Option holders do not
     exercise their Options at the Effective Time, there will be an ongoing
     accounting impact for the changes in the fair market value of the
     Recapitalization Consideration that is issuable upon exercise of such
     Options.) The total after-tax effect of the nonrecurring charges is $122
     million. Due to the nonrecurring nature of these charges, they have been
     excluded from the Pro Forma Condensed Statement of Consolidated
     Operations.     
   
 (9) Due to the nature of the Recapitalization, a comparison of historical and
     pro forma loss per share is not meaningful.     
   
(10) The pro forma loss per common share is based on an estimated 12,519,891
     weighted average shares outstanding and is calculated after preferred
     stock dividend requirements of $33.2 million on the Company's outstanding
     Series A Preferred Stock and $78.4 million on the Public Preferred Stock
     issued as a result of the Recapitalization. The number of weighted
     average shares assumes the Series A Preferred Stock does not convert
     during the first year of the transaction. The number of average shares of
     ESOP Preferred Stock committed to be released during the year were not
     included in the calculation as a common stock equivalent because the
     effect is anti-dilutive. Since no shares of ESOP Preferred Stock are
     allocated until December 31, the pro forma calculations assume no
     dividends are paid on allocated shares of ESOP Preferred Stock during the
     year ended December 31, 1993, and accordingly, dividends on ESOP
     Preferred Stock are not included in the pro forma loss per share. In
     addition, the pro forma calculations are based on the initial dividend
     rate of 10.25% for the Public Preferred Stock; however, the actual rate
     will be reset prior to Closing and the dividend rate could increase to a
     maximum of 11.375%. If the reset rate results in the maximum rate being
     11.375%, the loss per share would increase by $0.69 per share.     
        
     The underwriting agreements for Offerings are expected to provide that if
     the Offerings are consummated, the dividend rate on the Public Preferred
     Stock may be adjusted to permit the Depositary Preferred Shares to be
     sold at or closer to par, but if this is done, the number of Depositary
     Preferred Shares representing the Public Preferred Stock will be reduced
     so that the annual dividends will not exceed the stated maximum which was
     calculated based upon the dividend rate cap. If the Offering is not
     consummated, the dividend rate is subject to the cap.

 (1) The Company entered into an agreement to sell its U.S. flight kitchens
     over a period of months beginning in December 1993 through June 1994 and
     an agreement to acquire catering services for a seven year period. This
     adjustment eliminates $2 million of sales revenues and $27 million of
     compensation costs recorded in the first quarter of 1994 relating to the
     U.S. flight kitchens that were sold and adds estimated incremental
     catering costs of $22 million.     
   
 (2) To adjust compensation expense for the pro forma effect of the wage and
     benefit reductions and certain work-rule changes resulting from the
     employee investment that provide for wage and other compensation savings
     during the approximately six year period beginning at the Effective Time.
     The pro forma adjustment represents the estimated savings in the first
     quarter of 1994 assuming that such savings had commenced at the beginning
     of the prior year. The pro forma adjustment does not include any savings
     related to U2.     
   
 (3) The following reconciles the labor cost savings included in the Pro Forma
     Condensed Statement of Consolidated Operations to the value of the
     employee investments included in the Company Analysis of employee
     investments for 1994 (see "SPECIAL FACTORS--Certain Company Analyses"):

</TABLE>
   
 (4) To record non-cash compensation for shares of ESOP Preferred Stock
     committed to be released to employees during the period based on the
     average fair value of the ESOP Preferred Stock. For purposes of the pro
     forma adjustment, the average fair value of the ESOP Preferred Stock was
     assumed to be the initial purchase price of $120. The pro forma
     calculations assume that shares committed to be released in 1993 were
     allocated to participant accounts at the end of 1993. Thus, the portion of
     shares committed to be released in 1994 that will be used to satisfy
     dividends payable on allocated shares is charged to retained earnings
     rather than non-cash compensation expense. It is anticipated that in the
     first quarter of 1994, approximately 768,000 shares of ESOP Preferred
     Stock will be committed to be released, and that approximately 54,000 of
     these shares will be used for dividends.     
        
     Since future expense is dependent on the fair market value of the ESOP
     Preferred Stock, it is difficult to forecast and may vary significantly
     from the value in the pro forma adjustment. Changes in the price of a New
     Share directly affect the determination of the value of an ESOP Preferred
     Stock share. In addition, if the average value of a New Share exceeds
     $136 during the first 12 months after the Effective Date, additional
     shares of ESOP Preferred Stock will be issued to the Qualified Trust or
     reserved for issuance to the Non-Qualified Plan. Future expense is also
     affected by the premium associated with the dividend paying feature which
     shrinks over time as the dividend paying period is reduced.

   *    Assumes a dividend premium of $32.     
      
   **   To achieve the maximum increase in additional Shares, the price of a
        New Share must average at least $149.10 during the first 12 months
        after the Effective Date. If the average price of a New Share is less
        than or equal to $136, no additional shares of ESOP Preferred Stock
        will be issued.     
      
   ***  The additional shares will be released in a level fashion over the 69
        months of the ESOP.     
      
   **** Represents the increase for the quarter; subsequent increases are
        dependent on changes in the fair value of the ESOP Preferred Stock.
            
    
 (5) To record the interest expense on the Series A Debentures at an annual
     estimated interest rate of 9.0% and on the Series B Debentures at an
     annual estimated interest rate of 9.7%, and to record amortization of the
     underwriting discount. For purposes of the pro forma adjustment, the
     interest rates are based on the Initial Pricing. The actual rates will be
     reset prior to Closing and any upward reset is limited to an additional
     112.5 basis points. If the reset results in the actual rate being at the
     maximum interest rate, interest expense would increase by an additional $2
     million for the quarter. Further, if the Unions request prior to the
     Announcement Date that the Debentures contain a call provision, the actual
     rates may increase above the maximum.     
   
 (6) To record foregone interest income due to the reduction in the Company's
     average investment balance resulting from the Recapitalization. The pro
     forma adjustment is based on the Company's average earnings rate during
     the first quarter of 1994.     
   
 (7) To reverse $19 million of nonrecurring fees and expenses relating to the
     Recapitalization which were recorded in the first quarter of 1994.     
   
 (8) To adjust the provision (credit) for income taxes to reflect the tax
     effect of changes to pretax income at the statutory rate in effect during
     the first quarter of 1994. For purposes of the pro forma adjustment the
     book and tax employee stock ownership plan compensation charge are assumed
     to be the same.     
   
 (9) Due to the nature of the Recapitalization, a comparison of historical and
     pro forma loss per share is not meaningful.     
   
(10) The pro forma loss per common share is based on an estimated 12,547,163
     weighted average shares outstanding and is calculated after preferred
     stock dividend requirements of $9.4 million on the

    Company's outstanding Series A Preferred Stock, $19.6 million on the Public
    Preferred Stock issued as a result of the Recapitalization and $6.5 million
    on the ESOP Preferred Stock issued as a result of the Recapitalization. The
    dividends on the ESOP Preferred Stock relate to the estimated 3,073,974
    shares allocated at the end of 1993 (of the total 17,675,345 shares that
    will be allocated) and a dividend rate of 7%. The number of weighted
    average shares assumes the Series A Preferred Stock does not convert during
    the first year of the transaction. The number of average shares of ESOP
    Preferred Stock committed to be released during the period were not
    included in the calculation as a common stock equivalent because the effect
    is anti-dilutive. In addition, the pro forma calculations are based on the
    initial dividend rate of 10.25% on the Public Preferred Stock; however, the
    actual rate will be reset prior to closing and the dividend rate could
    increase to a maximum of 11.375%. If the reset rate results in the maximum
    rate being 11.375%, the loss per share for the quarter would increase by
    $0.17 per share.

   average shares:

 NOTES TO PRO FORMA CONDENSED STATEMENT OF CONSOLIDATED FINANCIAL POSITION     
       
                                 
                              MARCH 31, 1994     
   
 (1) To record the Recapitalization (as described in "THE PLAN OF
     RECAPITALIZATION--Terms and Conditions"). The entries assume that (i) the
     Offerings of Debentures and Depositary Preferred Shares representing
     interests in Public Preferred Stock are consummated, (ii) all in-the-money
     employee stock options are vested and exercised at the Effective Time
     using a cashless exercise mechanism, (iii) treasury stock held by the
     Company immediately prior to the Effective Time will convert into New
     Shares that remain outstanding after the Recapitalization and (iv)
     Convertible Company Securities that are outstanding immediately prior to
     the Effective Time will not convert into the Recapitalization
     Consideration at the Effective Time. The cashless exercise feature permits
     holders of Options to exercise them by surrendering to the Company a
     portion of the proceeds of the Option in lieu of paying the exercise price
     in cash. When the cashless exercise feature is used, each element of the
     Recapitalization Consideration that is issuable upon the exercise of such
     Options, is reduced proportionately, and the net Recapitalization
     Consideration (including the New Shares) that is issued is equal in value
     to the spread value of the Options exercised. See footnote number 8 to the
     Pro Forma Condensed Statement of Consolidated Operations for the year
     ended December 31, 1993.     
       
   
   (a) To record the proceeds from the Offerings of approximately $765
       million of Debentures and approximately $765 million of Depositary
       Preferred Shares representing interests in Public Preferred Stock, net
       of underwriting discount of $7 million for the Debentures and $25
       million for the Public Preferred Stock. (If the Offerings are not
       consummated, the Debentures and the Depositary Preferred Shares
       included in entry 1(c) and 1(d) will be issued to the holders of Old
       Shares upon redemption of the Redeemable Preferred Stock.)     
      
   (b) To record the cash payment to holders of Old Shares upon the
       redemption of the Redeemable Preferred Stock. The cash payment
       includes $25.80 per share plus proceeds from the sales of $31.10 face
       amount of Debentures and Depositary Preferred Shares representing
       interests in $31.10 liquidation preference of Public Preferred Stock
       (before deducting underwriting discounts), and assumes that the
       proceeds of the sales equals the face amount of the securities. The
       pro forma adjustment also includes the cash payment of $88 per share
       upon exercise of Options. (If the amount to be sold in the Offerings
       are reduced as discussed in entry 1(c) and 1(d), the amount paid to
       holders of Old Shares will be reduced.)     
      
   (c) To record the issuance of $382.5 million of principal amount of Series
       A Debentures and $382.5 million of principal amount of Series B
       Debentures. The Debentures are being recorded at their face amount on
       the assumption that they will be priced to trade at par, less the
       underwriting discount of $7 million. The actual rate on the Debentures
       will be reset prior to the Effective Time and the Debentures are
       subject to a maximum interest rate of 112.5 basis points above the
       Initial Pricing. The underwriting agreements for the Offerings are
       expected to provide that if the Offerings are consummated, the
       interest rate may be adjusted in order for the Debentures to be sold
       at or closer to par, in which case the principal amount of the
       Debentures will be reduced so that the annual interest expense will
       not exceed the stated maximum which was calculated based upon the rate
       cap. If the Offerings are not consummated and the interest rate
       exceeds the cap, the Debentures will be recorded at a discount.     
      
   (d) To record the issuance of Depositary Preferred Shares representing
       interests in $765 million liquidation preference of Public Preferred
       Stock, net of underwriting discount of $25 million. The Public
       Preferred Stock is recorded at its stated value of $.01 per share,
       with the excess of liquidation value over stated value and net of
       underwriting discount recorded as additional capital invested. The
       dividend rate on the Public Preferred Stock will be reset prior to
       Closing and is subject to a maximum of 11.375%. The underwriting
       agreements for the Offerings are expected to provide that if the
       Offering is consummated, the dividend rate may be adjusted in which
       case the     
 
                                      117
<PAGE>
 
          
       number of Depositary Preferred Shares will be reduced so that the
       annual dividends will not exceed the stated maximum which was
       calculated based upon the rate cap.     
      
   (e) To record the reclassification of Old Shares into New Shares and
       Redeemable Preferred Stock. The Redeemable Preferred Stock is assumed
       to immediately convert to cash, including proceeds from the sale of
       Debentures and Depositary Preferred Shares representing interests in
       the Public Preferred Stock. (The pro forma adjustments do not reflect
       the Redeemable Preferred Stock issued to the Company upon
       reclassification of the treasury stock because such shares are
       surrendered for cancellation immediately after issuance.)     
          
       The New Shares are recorded at their par value of $.01 per share.
       Following is a summary of the entries to additional capital invested
       and retained earnings (in millions):

 (2) To record the cash impact of the estimated fees and transaction expenses,
     including expenses for the Company, ALPA and the IAM, severance payments
     to terminated officers and flight kitchen employees and payments relating
     to the employment agreement with Mr. Greenwald.     
   
 (3) To record the tax effects relating to nonrecurring charges recognized as a
     result of the Recapitalization.     
   
 (4) To record the initial issuance of Class 1 ESOP Preferred Stock to the
     Leveraged ESOP for an aggregate purchase price of $228 million. The $228
     million was determined based on (i) 1,899,059 shares of Class 1 ESOP
     Preferred Stock expected to be issued in the first ESOP Tranche as of the
     Effective Time and (ii) an assumed purchase price of $120 per share. UAL
     and the Unions may, prior to the Effective Time, agree to increase or
     decrease the number of shares of Class 1 ESOP Preferred Stock sold at the
     Effective Time. The agreement with the ESOP Trustee provides that the
     number of shares of Class 1 ESOP Preferred Stock sold at the Effective
     Time shall be no more than 2,088,965 and no fewer than 1,709,153. The
     actual price per share for the first ESOP Tranche will be 1.38 times the
     average price of a New Share at the Effective Time. Thus, the ultimate
     amount recorded at the Effective Time will differ from the pro forma
     adjustment in order to reflect the actual number of shares issued and the
     average closing price of the New Shares.     
        
     Six additional ESOP Tranches will be issued to the Leveraged ESOP during
     the 69 months subsequent to the Effective Time, with the total shares of
     Class 1 ESOP Preferred Stock issued in the seven ESOP Tranches aggregating
     approximately 14,000,000 shares (subject to increase, see "THE PLAN OF
     RECAPITALIZATION--Establishment of ESOPs--Additional Shares"). The price
     for the subsequent ESOP Tranches will be as agreed between the Company and
     the ESOP Trustee at the time of each sale. As the subsequent ESOP Tranches
     are issued, the shares will be reported as a credit to additional capital
     invested based on the fair value of the stock when such issuances occur
     with a corresponding charge to "Unearned ESOP Preferred Stock."     
        
     The Unearned ESOP Preferred Stock recorded in the pro forma adjustment
     together with the Unearned ESOP Preferred Stock recorded from subsequent
     ESOP Tranches will be recognized as compensation expense over the
     approximately six year investment period as the shares are committed to be
     released. The difference between the compensation expense recorded, which
     is based on the fair value of the stock during an accounting period, and
     the recorded cost of the unearned ESOP Preferred Stock will be recorded to
     additional capital invested.

     The shares of Class 2 ESOP Preferred Stock will be recorded over the
     approximately six year investment period as the shares are committed to
     be contributed to the Non-Leveraged Qualified ESOP and credited to
     employees pursuant to the Supplemental ESOP with the offsetting entry
     being to compensation expense. The number of shares of Class 2 ESOP
     Preferred Stock that will be issued will be equal to 17,675,345 less the
     number of Shares of Class 1 ESOP Preferred Stock that will be sold to the
     Qualified Trust.     
        
     The ESOP Preferred Stock is convertible into New Shares at any time at
     the election of the ESOP Trustee at a rate of one New Share for each
     share of ESOP Preferred Stock (subject to adjustment). Primarily because
     of limitations imposed by the Internal Revenue Code, the ESOP consists of
     three major portions: (i) the Leveraged ESOP, the Non-Leveraged Qualified
     ESOP, and the Supplemental ESOP. Shares of ESOP Preferred Stock issued
     under the Leveraged ESOP and the Non-Leveraged Qualified ESOP will be
     held by the ESOP Trustee under the Qualified Trust. Under the
     Supplemental ESOP, shares will be credited as Book-Entry Shares when
     earned by employees, and will be issued to employees as New Shares,
     generally upon termination of employment. ALPA has the right to elect, at
     any time, before or after the Effective Time, that the Supplemental ESOP
     be maintained by the actual issuance of Class 2 ESOP Preferred Stock to a
     non-qualified trust established under the Supplemental Plan. In general,
     the Plan of Recapitalization is designed to maximize the number of shares
     of ESOP Preferred Stock that may be sold to the Qualified Trust. However,
     because of certain limitations imposed by the Internal Revenue Code, a
     portion of the equity interest to be obtained by the ESOP Trustee may not
     be sold to the Qualified Trust. The Class 1 ESOP Preferred Stock contains
     a fixed dividend feature which is intended to maximize the number of
     shares of Class 1 ESOP Preferred Stock that may be sold to the Qualified
     Trust consistent with the applicable provisions of the Internal Revenue
     Code. To the extent the Qualified Trust is unable to purchase the Class 1
     ESOP Preferred Stock, Class 2 ESOP Preferred Stock will be issued, to the
     extent permitted by the limitations of the Internal Revenue Code, to the
     ESOP Trustee pursuant to the Non-Leveraged Qualified ESOP. Class 2 ESOP
     Preferred Stock will not contain a fixed dividend. To the extent that
     Class 2 ESOP Preferred Stock cannot be issued to the ESOP Trustee because
     of the limitations of the Internal Revenue Code, the Company will credit
     Book-Entry Shares to accounts established for the employees.     
   
 (5) To record the issuance at par of one share of Class P Voting Preferred
     Stock, one share of Class M Voting Preferred Stock, and one share of
     Class S Voting Preferred Stock to the ESOP Trusts. The remaining Voting
     Preferred Stock will be issued when it is contributed to the Supplemental
     ESOP Trust. The Class P Voting Preferred Stock, the Class M Voting
     Preferred Stock and the Class S Voting Preferred Stock, which are
     referred to collectively as the Voting Preferred Stock, represent and
     permit, in connection with the establishment of the ESOPs, the exercise
     of voting power representing 55% (which under certain circumstances may
     be increased to up to 63%) of the voting power of the Company. See
     "DESCRIPTION OF SECURITIES--The Voting Preferred Stock." The ESOPs
     provide that upon the conversion of all the ESOP Preferred Stock into New
     Shares, each share of Voting Preferred Stock will be converted into one
     ten-thousandth of a New Share.     
   
 (6) To account for the cashless exercise of options in the event of the
     Recapitalization. (Amount of the entry is based on an assumed Old Share
     price at the Effective Time of approximately $131 per share.)     
   
 (7) Represents the offset to entries (2), (3), (6), (8), (9) and (11).     
   
 (8) To record the vesting of the unvested restricted stock as a result of the
     Recapitalization.     
   
 (9) To record 25,000 restricted shares to Mr. Greenwald that will vest at the
     Effective Time.     
   
(10) Does not reflect the issuance of four shares of Class I Preferred Stock,
     one share of Class Pilot MEC Preferred Stock, one share of Class IAM
     Preferred Stock, and three shares of Class SAM Preferred Stock. These
     stocks have a $.01 par value and nominal economic value. The Class I
     Preferred Stock

     will be issued to the Independent Directors and will have the power to
     elect such directors to the Board. The Class Pilot MEC Preferred Stock
     will be issued to the ALPA-MEC and will have the power to elect the ALPA
     Director. The Class IAM Preferred Stock will be issued to the IAM or its
     nominee and will have the power to elect the IAM Director. The Class SAM
     Preferred Stock will be issued to the Salaried and Management Director
     and to the senior executive at United who has primary responsibility for
     human resources and will have the power to elect the Salaried and
     Management Director. Such classes of stock are referred to collectively
     as the Director Preferred Stock. See "DESCRIPTION OF SECURITIES--The
     Director Preferred Stock." Upon the occurrence of an Uninstructed Trustee
     Action (as defined below), the Class Pilot MEC Preferred Stock will
     succeed to the voting power previously held by the Class P Preferred
     Stock, the Class IAM Preferred Stock will succeed to the voting power
     previously held by the Class M Preferred Stock and the Class SAM
     Preferred Stock will succeed to the voting power previously held by the
     Class S Preferred Stock. See "DESCRIPTION OF SECURITIES--The Director
     Preferred Stock--Uninstructed Trustee Actions."     
   
(11) To reverse $19 million of transaction fees and expenses recorded during
     the first quarter of 1994 because these expenses are included in entry
     (2).     
   
(12) The number of New Shares issued on a pro forma basis is based on Fully
     Diluted Old Shares assuming the Convertible Company Securities do not
     convert. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--

  The following unaudited Pro Forma Condensed Statements of Consolidated
Operations for the year ended December 31, 1993 and the three months ended
March 31, 1994, and the unaudited Pro Forma Condensed Statement of
Consolidated Financial Position as of March 31, 1994 for United and its
subsidiaries have been prepared to reflect the impact of the Recapitalization
on United, including: (i) the recognition of unearned ESOP Preferred Stock and
related ESOP capital as a result of the issuance of the first tranche of UAL
Class 1 ESOP Preferred Stock, (ii) the offering of Debentures and distribution
of proceeds to UAL, (iii) the recognition of the employee stock ownership plan
accounting charge, (iv) the reduction in salaries and related cost for the
anticipated impact of the wage and benefit reductions and certain work rule
changes and (v) the recognition of the anticipated benefits of the agreement
to sell the U.S. flight kitchens. The unaudited Pro Forma Condensed Statements
of Consolidated Operations were prepared as if the Recapitalization had
occurred on January 1, 1993. The unaudited Pro Forma Condensed Statement of
Consolidated Financial Position was prepared as if the Recapitalization
occurred on March 31, 1994.     
   
  The pro forma statements assume the Recapitalization is not accounted for as
an acquisition or merger and, accordingly, United's assets and liabilities
have not been revalued. The distribution to UAL of proceeds from the Offering
of Debentures is charged to additional capital invested.     
   
  The ESOPs are being accounted for in accordance with the American Institute
of Certified Public Accountants Statement of Position 93-6, "Employers'
Accounting for Employee Stock Ownership Plans" ("SOP"). For the Leveraged
ESOP, the Company will issue Class 1 ESOP Preferred Stock through seven ESOP
Tranches beginning at the Effective Time, thirteen months following the
Effective Time, annually thereafter for four years with a final ESOP Tranche
on January 1, 2000. As the Shares are issued to the Leverage ESOP, United will
report the issuance of shares as a credit to ESOP capital based on the fair
value of the Class 1 stock when such issuance occurs and report a
corresponding charge to unearned ESOP Preferred Stock. As shares of ESOP
Preferred are earned or committed to be released, compensation expense will be
recognized equal to the average fair value of the shares committed to be
released with a corresponding credit to unearned ESOP Preferred Stock. Any
differences between the fair value of the shares committed to be released and
the cost of the shares to the ESOP will be charged or credited to ESOP
capital. For the Non-Leveraged Qualified ESOP and the Supplemental ESOP, the
shares of Class 2 ESOP Preferred Stock will be recorded as the shares are
committed to be contributed to the ESOP, with the offsetting entry to
compensation expense. Compensation expense will be recorded based on the fair
value of the shares committed to be contributed to the ESOP, in accordance
with the SOP. The unearned ESOP Preferred Stock, ESOP capital and employee
stock ownership accounting charge will be recorded on United's books since
participants in the ESOP are employees of United.     
       
       
       
   
  The unaudited Pro Forma Condensed Statements of Consolidated Operations
include the recurring charges and credits which are directly attributable to
the Recapitalization, such as the interest expense arising from the
Debentures, the effects of the wage and benefit reductions and certain work-
rule changes resulting from the employee investment, and the employee stock
ownership plan accounting charge. No adjustments have been made to the pro
forma revenues and expenses to reflect the results of structural changes in
operations, such as U2, that might have been made had the changes been
consummated on the assumed effective dates for presenting pro forma results.
       
  The pro forma adjustments are based upon available information and upon
certain assumptions that United believes are reasonable. In addition, this
information should be read in conjunction with United's Annual Report on Form
10-K for the year ended December 31, 1993, and United's Quarterly Report on
Form 10-Q for the quarter ended March 31, 1994, which are included elsewhere
in this Proxy Statement/ Prospectus and which include United's Consolidated
Financial Statements, the related notes thereto and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

(1) United entered into an agreement to sell its U.S. flight kitchens over a
    period of months beginning in December 1993 through June 1994, and an
    agreement to acquire catering services for a seven year period. This
    adjustment eliminates $28 million of sales revenues and $191 million of
    compensation costs recorded in 1993 relating to the U.S. flight kitchens
    that were sold, and adds estimated incremental catering costs of $131
    million.     
   
(2) To adjust compensation expense for the pro forma effect of wage and
    benefit reductions and certain work-rule changes resulting from the
    employee investment that provide for wage and other compensation savings
    during the approximately six year period beginning at the Effective Time.
    The pro forma adjustment represents the estimated savings in the 12 months
    assuming that such savings had commenced at the beginning of the period.
    The pro forma adjustment does not include any savings related to U2.     
   
(3) The following reconciles the labor cost savings included in the Pro Forma
    Condensed Statement of Consolidated Operations to the value of the
    employee investments included in the Company Analysis of employee
    investments for 1994 (see "SPECIAL FACTORS--Certain Company Analyses"):

(4) To record non-cash compensation for shares of ESOP Preferred Stock
    committed to be released to employees during the period based on the
    average fair value of such ESOP Preferred Stock. The average fair value of
    the ESOP Preferred Stock is based on two components: (1) the average fair
    value of the New Shares into which the ESOP Preferred Stock is convertible
    plus (2) a premium attributable to the dividend paying feature of the ESOP
    Preferred Stock. For purposes of the pro forma adjustment, the average
    fair value of the ESOP Preferred Stock was assumed to be the initial
    purchase price of $120. In future years, it is anticipated that the ESOP
    Preferred Stock price, for purposes of computing the employee stock
    ownership plan accounting charge, will be determined by an independent
    appraiser who will value both components. Additionally, in future years,
    the shares committed to be released that are used to satisfy the dividends
    payable on previously allocated shares will be charged to retained
    earnings rather than compensation expense.     
       
    The shares of the ESOP Preferred Stock committed to be released are a
    fraction of the original ESOP Preferred Stock shares. It is anticipated
    the shares will be released in a level fashion over the 69 months of the
    ESOP taking into account the partial period in 1994 and 2000. This would
    result in approximately 3.07 million ESOP Preferred Stock shares committed
    to be released in each full calendar year. Shares released in a partial
    year would be pro rated.     
       
    Since future expense is dependent on the fair market value of the ESOP
    Preferred Stock it is difficult to forecast and may vary significantly
    from the value in the pro forma adjustment. Changes in the price of a New
    Share directly affect the determination of the value of an ESOP Preferred
    Stock share. In addition, if the average value of a New Share exceeds $136
    during the first 12 month after the Effective Date, additional     
 
                                      123
<PAGE>
 
     
  shares of ESOP Preferred Stock will be issued to the Qualified Trust or
  reserved for issuance to the Non-Qualified Plan to increase the ESOP's
  ownership from 55% to 63%. Future expense is also affected by the premium
  associated with the dividend paying feature which shrinks over time as the
  dividend paying period is reduced.     
         
       
   
   Following is a summary of the impact to the employee stock ownership plan
   accounting charge of a range of fair market values;

(5) To record interest expense of $72 million on the Series A Debentures at an
    annual estimated interest rate of 9.0% and on the Series B Debentures at
    an annual estimated interest rate of 9.7%, and to record amortization of
    the underwriting discount. The pro forma adjustment also includes foregone
    interest income due to the reduction in United's average investment
    balance resulting from the transaction. For purposes of the pro forma
    adjustment, the interest rates on the Debentures are based on the Initial
    Pricing. The actual rates will be reset prior to Closing and the reset is
    limited to an additional 112.5 basis points. If the reset results in the
    actual rate being at the maximum interest rate, interest expense would
    increase by an additional $9 million for the year. Further, if the Unions
    request prior to the Announcement Date that the Debentures contain a call
    provision, the actual rates could increase above the cap.     
       
    The underwriting agreements for the Offerings are expected to provide that
    if the Offerings are consummated, the interest rates may be set above the
    cap to permit the Debentures to be sold at or

    closer to par, but if this is done, the principal amount of the Debentures
    will be reduced so that the interest payable will not exceed the stated
    maximum which was calculated based upon the interest rate cap. If the
    Offerings are not consummated, the interest rates are subject to the cap.
        
   
(6) To adjust the provision (credit) for income taxes to reflect the tax
    effect of changes to pretax income at the statutory rate in effect during
    1993. For purposes of the pro forma adjustment, the book and tax employee
    stock ownership plan compensation charge are assumed to be the same.     
   
(7) If the Recapitalization is consummated, United expects to recognize
    nonrecurring charges of approximately $44 million relating to additional
    severance benefits for employees terminated as a result of the sale of the
    flight kitchens, up to $49.15 million of transaction fees and expenses
    incurred by ALPA, the IAM and certain advisors in connection with the
    structuring and establishment of the ESOPs, $30 million for United's
    transaction fees and expenses, $17 million of compensation expense
    relating to vesting the unvested restricted stock as a result of the
    change in control, $21 million of payments and benefits to Mr. Greenwald
    and officers who are retiring at the Effective Time, and $13 million of
    compensation expense (based on an assumed Old Share price of approximately
    $131 at the Effective Time) relating to the vesting of unvested Options ad
    the implementation of a feature that provides for cashless exercise of
    Options in the event of the Recapitalization. (The existing Option holders
    are only entitled to utilize the cashless exercise feature if the
    Recapitalization occurs. The pro forma financial information assumes all
    in-the-money Options are exercised at the Effective Time and, since the
    cashless exercise results in variable plan accounting, there is an initial
    nonrecurring charge for the cashless exercise feature but no ongoing
    impact; however, if Option holders do not exercise their Options at the
    Effective Time, there will be an ongoing accounting impact for the changes
    in the fair market value of the Recapitalization Consideration that is
    issuable upon exercise of such Options.) The total after-tax effect of the
    nonrecurring charges is $122 million. Due to the nonrecurring nature of
    these charges, they have been excluded from the Pro Forma Condensed
    Statement of Consolidated Operations.     
   
(8) In the first quarter of 1994, United began recording certain air
    transportation price adjustments, which were previously recorded as
    commission expense, as adjustments to revenue. Historical operating
    revenue and expense amounts have been adjusted to conform with the current
    presentation.

                     THREE MONTHS ENDED MARCH 31, 1994     
   
(1) United entered into an agreement to sell its U.S. flight kitchens over a
    period of months beginning in December 1993 through June 1994, and an
    agreement to acquire catering services for a seven year period. This
    adjustment eliminates $2 million of sales revenues and $27 million of
    compensation costs recorded in the first quarter of 1994 relating to the
    U.S. flight kitchens that were sold, and adds estimated incremental
    catering costs of $22 million.     
   
(2) To adjust compensation expense for the pro forma effect of wage and benefit
    reductions and certain work-rule changes resulting from the employee
    investment that provide for wage and other compensation savings during the
    approximately six year period beginning at the Effective Time. The pro
    forma adjustment represents the estimated savings in the first quarter of
    1994 assuming that such savings had commenced at the beginning of the prior
    year. The pro forma adjustment does not include any savings related to U2.
        
   
(3) The following reconciles the labor cost savings included in the Pro Forma
    Condensed Statement of Consolidated Operations to the value of the employee
    investments included in the Company Analysis of employee investments for
    1994 (see "SPECIAL FACTORS--Certain Company Analyses"):

</TABLE>
   
(4) To record non-cash compensation for shares of ESOP Preferred Stock
    committed to be released to employees during the period based on the
    average fair value of the ESOP Preferred Stock. For purposes of the pro
    forma adjustment, the average fair value of the ESOP Preferred Stock was
    assumed to be the initial purchase price of $120. The pro forma
    calculations assume that shares committed to be released in 1993 were
    allocated to participant accounts at the end of 1993. Thus, the portion of
    shares committed to be released in 1994 that will be used to satisfy
    dividend payable on allocated shares is charged to retained earnings rather
    than non-cash compensation expense. It is anticipated that in the first
    quarter of 1994, approximately 768,000 shares of ESOP Preferred Stock will
    be committed to be released, and that approximately 54,000 of these shares
    will be used for dividends.     
       
    Since future expense is dependent on the fair market value of the ESOP
    Preferred Stock, it is difficult to forecast and may vary significantly
    from the value in the pro forma adjustment. Changes in the price of a New
    Share directly affect the determination of the value of an ESOP Preferred
    Stock share. In addition, if the average value of a New Share exceeds $136
    during the first 12 month after the Effective Date, additional shares of
    ESOP Preferred Stock will be issued to the Qualified Trust or reserved for
    issuance to the Non-Qualified Plan. Future expense is also affected by the
    premium associated with the dividend paying feature which shrinks over
    time as the dividend paying period is reduced.

                         NOTES TO PRO FORMA CONDENSED
                  STATEMENT OF CONSOLIDATED FINANCIAL POSITION
                                 
                              MARCH 31, 1994     
   
(1) To record the cash impact of the estimated fees and transaction expenses,
    including expenses for United, ALPA and the IAM, severance payments to
    terminated officers and flight kitchen employees, and payments relating to
    the employment agreement with Mr. Greenwald.     
   
(2) To record the tax effects relating to nonrecurring charges recognized as a
    result of the transaction.     
   
(3) To record the offering of $382.5 million of Series A Debentures and $382.5
    million of Series B Debentures and to record the distribution of proceeds
    to UAL. The Debentures are being recorded at their face amount based on the
    assumption that they will be priced to trade at par, less the underwriting
    discount of $7 million. The actual rate on the Debentures will be reset
    prior to the Effective Time and the Debentures are subject to a maximum
    interest rate of 112.5 basis points above the Initial Pricing. The
    underwriting agreements are expected to provide that if the offering is
    consummated, the interest rate may be set above the cap in order for the
    Debentures to be sold at or close to par, in which case the principal
    amount of the Debentures will be reduced so that the annual interest
    expense will not exceed the stated maximum which was calculated based upon
    the rate cap. If the offering is not consummated and the interest rate
    exceeds the cap, the Debentures will be recorded at a discount.     
   
(4) To record the ESOP capital as a result of the initial issuance of shares of
    UAL's Class 1 ESOP Preferred Stock to the Qualified Trust for an aggregate
    purchase price of $228 million and to record the related charge to unearned
    ESOP Preferred Stock. The $228 million was determined based on (i)
    1,899,059 shares of Class 1 ESOP Preferred Stock expected to be issued in
    the first ESOP Tranche as of the Effective Time and (ii) an assumed
    purchase price of $120 per share. UAL and the Unions may, prior to the
    Effective Time, agree to increase or decrease the number of shares of Class
    1 ESOP Preferred Stock sold at the Effective Time. The agreement with the
    ESOP Trustee provides that the number of shares of Class 1 ESOP Preferred
    Stock sold at the Effective Time shall be no more than 2,088,965 and no
    fewer than 1,709,153. The actual price per share for the first ESOP Tranche
    will be 1.38 times the average price of a New Share at the Effective Time.
    Thus, the ultimate amount recorded at the Effective Time will differ from
    the pro forma adjustment in order to reflect the actual number of shares
    issued and the average closing price of the New Shares.     
       
    Six additional ESOP Tranches will be issued to the Leveraged ESOP during
    the 69 months subsequent to the Effective Time, with the total shares of
    Class 1 ESOP Preferred Stock issued in the seven ESOP Tranches aggregating
    approximately 14,000,000 shares (subject to increase, see "THE PLAN OF
    RECAPITALIZATION--Establishment of ESOPs--Additional Shares). The price for
    the subsequent ESOP Tranches will be as agreed between the Company and the
    ESOP Trustee at the time of each sale. As the subsequent ESOP Tranches are
    issued, the shares will be reported as a credit to additional capital
    invested based on the fair value of the stock when such issuances occur
    with a corresponding charge to "Unearned ESOP Preferred Stock."     
       
    The Unearned ESOP Preferred Stock recorded in the pro forma adjustment
    together with the Unearned ESOP Preferred Stock recorded from subsequent
    ESOP Tranches will be recognized as compensation expense over the
    approximately six year investment period as the shares are committed to be
    released. The difference between the compensation expense recorded, which
    is based on the fair value of the stock during an accounting period, and
    the recorded cost of the unearned ESOP Preferred Stock will be recorded to
    ESOP capital.     
       
    ESOP capital will also be recorded over the approximately six year
    investment period as the shares of UAL's Class 2 ESOP Preferred Stock are
    committed to be contributed to the Non-Leveraged Qualified ESOP and
    credited to employees pursuant to the Supplemental ESOP with the offsetting
    entry being to     
 
                                      130
<PAGE>
 
       
    compensation expense. The number of shares of Class 2 ESOP Preferred Stock
    that will be issued will be equal to 17,675,345 less the number of shares
    of Class 1 ESOP Preferred Stock that will be sold to the Qualified ESOP.
        
   
(5) To account for the cashless exercise of options in the event of the
    Recapitalization. (Amount of the entry is based on an assumed Old Share
    price at the Effective Time of approximately $131 per share.)     
   
(6) To record 25,000 restricted shares to Mr. Greenwald that will vest at the
    Effective Time.     
   
(7) Represents the offset to entries (1), (2), (5), (6), (8) and (9).     
   
(8) To record the vesting of the unvested restricted stock as a result of the
    Recapitalization.     
   
(9) To reverse $19 million of transaction fees and expenses recorded during the
    first quarter of 1994 because these expenses are included in entry (1).

Preferred Shares) and Debentures, (iii) redemption of the Redeemable Preferred
Stock for cash and proceeds from the Offerings and (iv) the issuance of the
first tranche of Class 1 ESOP Preferred Stock, the Voting Preferred Stock and
the Director Preferred Stock. The table should be read in conjunction with the

COMPENSATION OF DIRECTORS; EFFECT OF "CHANGE IN CONTROL"
 
  The directors receive an annual retainer of $20,000 and are paid $1,000 for
each meeting attended. The Chairmen of the Audit, Compensation, Nominating and
Pension and Welfare Plans Oversight Committees receive an additional retainer
of $3,000 per year. Each member of a committee receives a fee of $1,000 for
each committee meeting attended. In support of a cost reduction effort
announced in January 1993, directors' compensation as reported above was
reduced 10%. Directors also receive 100 Old Shares annually. Directors who are
officers of the Company or of any subsidiary do not receive any retainer fee,
meeting fee or Old Shares for their service on the Board of Directors or any
committee.
 
  Non-employee directors are eligible to participate in a retirement income
plan (the "Retirement Plan") if they have at least five years of service on the
date of retirement and are not otherwise eligible to receive pension benefits
from the Company or any of its subsidiaries. If a retiring director has at
least ten years of service and is age 70 or over at retirement, he or she is
entitled to a life annuity equal to the greater of $20,000 per year or the
annual retainer fee at retirement. Reduced benefits are available if the
director has less than ten years of service or if retirement occurs before age
70. For these purposes, a director who is a director at the time of a "change
in control" of the Company is credited with three additional years of service,
is deemed to have satisfied the five-year minimum service requirement and is
deemed to be three years older than his or her actual age. Surviving spouse
benefits are available in some cases. A trust (the "Trust") has been created to
serve as a source of payments of benefits under this retirement plan. The Trust
becomes irrevocable upon the occurrence of a "change in control."
 
  Under the Company's travel policy for directors (the "Travel Policy"), each
director of the Company, his or her spouse and their eligible dependent
children are entitled to free transportation on United. The directors are
reimbursed by the Company for additional income taxes resulting from the
taxation of these benefits. The average cost of supplying these benefits for
each director in 1993, including cash payments made in January, 1994 for income
tax liability, was $25,300. The Company also has a policy pursuant to which
each director is entitled to free cargo shipment on United. A director (and his
or her spouse and eligible
 
                                      138
<PAGE>
 
dependent children) serving as such at the time of a "change in control" is
entitled to continue such benefits thereafter for life.
 
  The transactions contemplated by the Plan of Recapitalization will constitute
a "change in control" for purposes of the Travel Policy, the Retirement Plan
and the Trust.

                             EXECUTIVE COMPENSATION
 
                 UAL CORPORATION COMPENSATION COMMITTEE REPORT
 
PHILOSOPHY
 
  The Company's officer compensation program is designed to attract, retain and
motivate top quality and experienced officers. The program provides industry
competitive compensation opportunities, supports a pay-for-performance culture
and emphasizes pay-at-risk. The program is heavily oriented toward incentive
compensation that is tied to the annual and longer-term financial performance
of the Company and to its longer-term return to stockholders.
 
COMPONENTS
 
  There are two components to the executive compensation program:
 
  . Cash compensation.
 
  .Stock compensation.
 
  The cash compensation program is comprised of base salary and annual cash
incentive compensation. Base salaries are competitive with other large domestic
air carriers, which include the three largest of the five carriers on the
Relative Market Performance Graph below. Base salaries are substantially less
than other corporations of comparable size.
 
  Annual incentive compensation provides an opportunity for additional
earnings. An annual incentive pool is created based upon the Company's
earnings; each year the Compensation Committee approves a schedule of annual
incentive pool funding relative to specified earnings targets. The CEO
recommends to the Committee incentive awards for each officer based upon an
assessment of each such officer's contribution over the preceding year. The
assessment is based on, among other things, an appraisal prepared annually for
each officer on his or her managerial skills and the performance by him or her
of assigned responsibilities. Before making a recommendation, the CEO will
discuss such appraisals with other members of senior management and will
consider these discussions, along with an overall assessment of Company
performance and industry competitive data, in making a recommendation to the
Compensation Committee on incentive awards for each officer. The Compensation
Committee determines the award for the CEO based upon a comparable process and
makes a final determination on incentive awards for all other officers.
 
  The stock compensation program is comprised of stock options and restricted
stock. Stock compensation gives each officer the opportunity to become a
stockholder of the Company. Stock grants are set in consideration of airline
industry practice using the same industry peer group for base salary and annual
incentive compensation. Stock grants are also set in consideration of
individual performance and contribution. The CEO recommends to the Compensation
Committee stock option and/or restricted stock grants for each officer; there
are no specific target award levels or weighting of factors considered in
determining stock grants. The Compensation Committee determines stock awards
for the CEO based upon a comparable process and
 
                                      139
<PAGE>
 
makes a final determination on stock awards for all other officers. Options and
restricted shares typically are granted in alternating years (options in one
year, restricted stock in the next year, etc.).
 
  Stock options may not be granted at less than fair market value on the date
of grant. Stock options carry a ten-year term and have exercise vesting
restrictions that lapse ratably over a four-year period. Restricted shares have
vesting restrictions of up to 5 years.
 
  The officer compensation program in total, although primarily focused on
promoting pay-for-performance and emphasizing pay-at-risk, is heavily oriented
toward stockholder interests through the use of long-term stock incentives that
create a direct linkage between executive rewards and increased stockholder
value. The long-term incentive component, which is comprised totally of stock-
based incentives, represents over half of the total income opportunity for the
officers.
 
CEO COMPENSATION
 
  At Mr. Wolf's request, his salary, upon joining United in 1987, was set at
$575,000, which was $75,000 less than his predecessor was paid. During 1992,
Mr. Wolf's base salary was increased for the first time since joining the
Company in 1987 to $675,000. This increase was based primarily on a qualitative
review of performance factors and his contributions and leadership in among
other things, creating the most comprehensive route structure of any carrier in
the world. Further, additional factors considered were that his salary of
$575,000 approximated the bottom tenth percentile of other chief executive
officers at U.S. companies exceeding $10 billion in annual revenue and that his
salary had not been increased since joining the Company in 1987.
 
  On February 14, 1993, in support of a cost reduction effort, Mr. Wolf
rescinded his raise of $100,000 and returned to his 1987 starting salary of
$575,000. On October 27, 1993, the Compensation Committee approved an increase
in Mr. Wolf's pre-reduction salary by $50,000, to $725,000. This increase was
based primarily on a qualitative review of performance factors and his
continuing contributions and leadership during an extremely difficult time in
the airline industry, and as an attempt to partially close the gap between his
salary and that of CEOs of other large corporations, especially in light of the
fact that he had foregone salary increases during most of his six year tenure
at the Company. On November 1, 1993, Mr. Wolf's salary was reinstated to its
1992 rate of $675,000 per annum, but Mr. Wolf asked the Compensation Committee
to defer his October 1993 increase, which was subsequently implemented on April
1, 1994.
 
  Mr. Wolf received no cash incentive award for 1993 performance. No stock
options or restricted stock were granted to Mr. Wolf during 1993.
 
COMPENSATION FOR THE OTHER NAMED OFFICERS
 
  Base salary rates for the other named executive officers were reduced 5% from
their 1992 levels in February 1993 in support of a cost reduction effort. Base
salaries remained at the reduced levels until September 1993 (November 1993 for
Mr. Pope), at which time they were restored to their 1992 levels. In keeping
with the Compensation Committee's philosophy of providing compensation to
attract, retain and motivate top quality and experienced officers, increases
averaging 6.3% were implemented in recognition of a negative competitive
differential in salary levels at the Company as compared to other large
corporations and because of cost of living increases. None of the other named
executive officers received a cash incentive award for 1993 performance. Each
received a restricted stock grant, subject to the normal restricted stock grant
terms described earlier pursuant to the Company's normal grant schedule, the
amount of which took into consideration the need for a retention mechanism due
to the fact that no payments had been made under the Incentive Plan for three
years.

COMMITTEE ACTIONS REGARDING CHANGES IN CONTROL     
 
  As described below under "--Employment Contracts and Change in Control
Arrangements," during 1993 the Compensation Committee, as part of an overall
review and after consultation with an independent compensation and benefits
consultant and with outside counsel, determined to authorize, and the Company
and United thereafter entered into, amendments to the Company's employment
contract with Mr. Wolf (originally entered into in 1987) and to an employment
contract and severance agreements with other named executive officers, new
severance agreements with additional executive officers and amendments to
agreements with Company officers to provide for the automatic vesting of
outstanding stock options, and the confirmation of such treatment for
restricted stock awards, upon a "change in control" of the Company.
 
  These changes were made in connection with the first overall review of these
arrangements in over three years and were intended in part to achieve greater
uniformity in the treatment of the Company's executive officers. The
Compensation Committee believes it is important to take steps to maintain a
stable management team. Revising, amending and adding these various agreements
was an important step in this endeavor. These changes also achieved greater
uniformity in severance and change in control policy than had previously
existed.
 
OMNIBUS BUDGET RECONCILIATION ACT OF 1993
 
  The Compensation Committee reviewed and discussed the impact of Section
162(m) of the Internal Revenue Code on the Company's executive compensation
programs. As a result of this review, the Company, as an integral part of and
conditional upon approval of the Recapitalization, is proposing changes to its
incentive compensation program for named executive officers. These changes will
make the program totally formula-based and will bring the program fully into
compliance with the proposed regulations. The Company is also proposing a
change to its stock incentive compensation program to place a per person cap on
stock grants and to provide performance-based restricted stock awards to the
named executive officers. These changes will cause all future incentive
compensation awards thereunder to be in full compliance with the proposed
regulations.
 
COMPENSATION CONSULTANT AND COMPETITIVE DATA
 
  The Committee consults with independent compensation advisors on executive
compensation matters. The Committee also has access to competitive data on
compensation levels for officer positions.

    during the fiscal year associated with travel privileges.
   
(2) The restricted stock granted in 1993 vests 20% per year, from the time of
    grant, over a five year period. All restricted stock granted in 1991 vests
    100% after five years, except that the grant to Mr. O'Gorman vests 25% per
    year, from the time of grant, over a four year period. The number and
    aggregate value, respectively, of restricted holdings at fiscal year-end
    is: Mr. Wolf 15,000 Old Shares, $2,190,000; Mr. Pope 32,000 Old Shares,
    $4,672,000; Mr. O'Gorman 10,500 Old Shares, $1,533,000; Mr. Guyette 13,500
    Old Shares, $1,971,000; Mr. Nagin 15,300 Old Shares, $2,233,800. No
    dividends have been paid on these Old Shares, but officers have a right to
    retain any dividends paid on restricted shares.     
(3) Amounts represent the total reportable compensation attributable to the

(5) The 225,000 Old Share option granted to Mr. Wolf in 1991 and the 110,000
    Old Share option granted to Mr. Pope in 1992 were granted with exercise
    prices in excess of the then current market price. In Mr. Wolf's case,
    75,000 of the Options are exercisable at $147.875 on May 29, 1993, 50,000
    at $170.056 on May 29, 1994, 50,000 at $195.565 on May 29, 1995, and 50,000

  The above illustration is based on retirement at age 65 and selection of a
straight life annuity (other annuity options are available, which would reduce
the amounts shown above). The amount of the normal retirement benefit under the
plan is the product of 1.6% times years of credited participation in the plan
times final average compensation (highest five of last ten years of covered
compensation). The retirement benefit amount is not offset by the participant's
Social Security benefit. Compensation covered by the plan includes salary and
cash bonuses. Credited years of participation with the Company and United for
persons named in the cash compensation table are as follows: Mr. Wolf--5 years;
Mr. Pope--5 years; Mr. Guyette--25 years; Mr. O'Gorman--21 years; and Mr.
Nagin--4 years. The amounts shown do not reflect limitations imposed by
Internal Revenue Code on retirement benefits which may be paid under plans
qualified under the Internal Revenue Code. United has agreed to provide under
non-qualified plans the portion of the retirement benefits earned under the
pension plan which would otherwise be subject to Internal Revenue Code
limitations.
 
  The Company has agreed to supplement Messrs. Wolf's and Pope's benefits under
the qualified pension plan and United has agreed to supplement Messrs. Nagin's
and O'Gorman's benefits under the qualified pension plan, in each case by
granting them credit for their prior airline service--22 years for Mr. Wolf, 10
years for Mr. Pope, 6 years for Mr. O'Gorman, and 8 years for Mr. Nagin. Mr.
Wolf's benefit will be offset by retirement benefits he is entitled to under
any of the plans of his prior employers except Tiger International, Inc.
 
  Pursuant to the Officer Agreements, upon their retirements in accordance with
the Plan of Recapitalization, each of Messrs. Wolf, Pope and Nagin will be
entitled to receive a cash payment in an amount calculated to be sufficient to
provide additional annual retirement income commencing at age 56 (age 55 in the
case of Mr. Pope) of approximately $240,000, $12,000 and $32,000, respectively.

EMPLOYMENT CONTRACTS AND CHANGE IN CONTROL ARRANGEMENTS
 
  The Company and United originally entered into the Officer Agreements with
Mr. Wolf and Mr. Pope when they joined the Company in 1987 and 1988,
respectively, (as subsequently amended and restated, the "Employment
Agreements").
 
  In the event of a change in control of the Company or United followed by the
termination of his employment, Mr. Wolf would be entitled to a payment equal to
from one to three times his salary and anticipated bonus deemed equal to his
salary, depending upon the circumstances of his termination, together with
certain other amounts. In the event of a change in control of the Company or
United followed by a termination of his employment, Mr. Pope would be entitled
to a payment equal to from one to three times his salary and anticipated bonus
of not less than $100,000, depending upon the circumstances of his termination,
together with certain other amounts.
 
  The Employment Agreements also provide for the continuance of certain
specified employee benefits for a period of years equal to the number of years
of compensation included in the severance payment and, depending on the
circumstances applicable to an executive, possibly beyond that time.
 
 
                                      144
<PAGE>
 
   
  Each other executive officer of United is a party to a severance agreement
(the "Severance Agreements") with United that provides certain benefits if the
executive's employment with United is terminated (1) by the Company without
"cause" (as defined in the Severance Agreements) or (2) by the executive for
"good reason" (as defined in the Severance Agreements) in either case, within
three years following a "change in control" (as defined in the Severance
Agreements). Upon such a termination of employment, the executive officer will
be entitled to receive (1) a cash payment equal to 3 times the sum of (a) the
greater of the executive's base salary as in effect on the date of the change
in control or as in effect on the date his or her employment terminates plus
(b) the average of the greater of the bonuses paid to the executive with
respect to the three years preceding the change in control or the bonuses paid
to the executive with respect to the three years preceding his or her
termination of employment, (2) continuation of travel privileges (and partial
tax reimbursement) on United for the executive and his or her spouse and other
dependents for three years following termination of employment (and for life
thereafter if the executive would have qualified for retiree travel privileges
had his or her employment continued during such three-year period), (3)
coverage under United's medical and other welfare benefits for a period of
three years following the date of termination (and for life thereafter if the
executive would have qualified for retiree medical benefits had his or her
employment continued during such three-year period), (4) a lump sum payment
equal to the value of the pension benefits (including any early retirement
benefits) that the executive officer would have earned under United's pension
plans and arrangements had the executive officer continued to be employed for
an additional three years and (5) a lump sum payment equal to the amounts that
United would have paid on behalf of the executive officer with respect to split
dollar life insurance policies in effect for the executive. The concessions to
be implemented with respect to Salaried and Management Employees pursuant to
the Plan of Recapitalization could be a "good reason" event entitling such
other executive officers of United to terminate their employment and receive
the benefits described above. The Company has requested that such individuals
agree to waive the "good reason" event arising as a result of the
implementation of such concessions. All of such other executive officers have
provided such a waiver.     
 
  Pursuant to the Officer Agreements, upon their retirements, in accordance
with the Plan of Recapitalization, each of Messrs. Wolf, Pope, and Nagin will
be entitled to receive a cash payment in respect of certain split dollar life
insurance policies in effect for them of approximately $195,000, $160,000 and
$140,000 respectively.
 
  During 1993 the Company amended stock option and restricted stock agreements
with each of the named executive officers to provide for the automatic vesting
of outstanding stock options, and for confirmation of such treatment for
restricted stock awards, upon a change in control.
 
RULE 405 DISCLOSURE
 
  Form 5s for 1993, with respect to one exempt transaction each, were
inadvertently filed late for Messrs. O'Gorman and Wolf due to an error in the
Company's recordkeeping. The Company, and not the individuals, takes
responsibility for effecting these filings.
 
           APPROVAL OF AMENDMENTS TO THE 1981 INCENTIVE STOCK PROGRAM
 
  ON MARCH 25, 1994, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDED, IN
CONNECTION WITH THE APPROVAL OF THE RECAPITALIZATION, THAT THE STOCKHOLDERS
VOTE FOR APPROVAL OF AMENDMENTS (THE "1981 STOCK PROGRAM AMENDMENT") TO THE
1981 INCENTIVE STOCK PROGRAM (THE "1981 STOCK PROGRAM") TO ADD 1,200,000 NEW
SHARES (SUBJECT TO ADJUSTMENT AS HEREINAFTER DESCRIBED) TO THE MAXIMUM NUMBER
OF SHARES WITH RESPECT TO WHICH GRANTS MAY BE MADE UNDER THE 1981 STOCK
PROGRAM.
 
  The full text of the 1981 Stock Program Amendment is filed as an exhibit to
the Registration Statement. The following summary of the 1981 Stock Program is
qualified in its entirety by the full text of the 1981 Stock Program and the
1981 Stock Program Amendment.
 
                                      145
<PAGE>
 
   
  ADMINISTRATION. The 1981 Stock Program is administered by the Compensation
Committee of the Board. Upon consummation of the Plan of Recapitalization, the
1981 Stock Program will be administered by the Compensation Administration
Committee of the Board.     
   
  SHARES SUBJECT TO PROGRAM. As initially approved by the stockholders on April
29, 1982, 1,300,000 shares of common stock were issuable under the 1981 Stock
Program. On April 24, 1986 and April 25, 1991, an additional 2,000,000 and
1,000,000 shares, respectively, were authorized for issuance under the 1981
Stock Program. The amendments recommended by the Board would make 1,200,000
(subject to adjustment if additional shares become issuable to the employee
groups in accordance with the Plan of Recapitalization, see "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Additional Shares.") New Shares
available for issuance under the 1981 Stock Program. Stock issuable under the
1981 Stock Program may be newly issued or treasury shares. The Compensation
Committee may at any time and from time to time, in its sole discretion,
allocate any or all of such shares for issuance pursuant to grants of incentive
stock options ("ISOs"), under Section 422 of the Internal Revenue Code, stock
options not intended to qualify under Section 422 of the Internal Revenue Code
("NQSOs") and stock appreciation rights ("SARs").     
   
  PARTICIPATION. Options and SARs are granted by the Compensation Committee
only to officers and key employees (including officers who may also be
directors) of the Company or any of its subsidiaries. There is currently no
specific limitation on the number of New Shares that may be optioned to any
individual (or made subject to an SAR) under the 1981 Stock Program. The
amendments recommended by the Board would limit the number of New Shares with
respect to which options may be granted under the 1981 Stock Program to any
individual during any two-year period to 125,000 (250,000 with respect to
grants made to any new employee as a condition of employment), subject to
adjustment if additional shares become issuable to the employee groups in
accordance with the Plan of Recapitalization. See "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Additional Shares."     
   
  STOCK OPTIONS. The option price for ISOs and NQSOs may not be less than 100%
of the fair market value of the common stock on the date of grant. The closing
price of the common stock on the New York Stock Exchange on May 25, 1994 was
$116 7/8. The duration of options granted under the 1981 Stock Program cannot
exceed ten years.     
 
  STOCK APPRECIATION RIGHTS. SARs may be granted exercisable in cash, or in
common stock, or in a combination of cash and common stock. SARs may be granted
to any participant in the 1981 Stock Program independent of or in tandem with
an NQSO. On exercise of an SAR, the holder will receive up to 100% of the
appreciation in fair market value of the shares subject to the SAR. In the case
of a tandem SAR, the appreciation shall be measured from the option price. All
of the SARs which have been issued under the 1981 Stock Program have been
tandem SARs. Exercise of an SAR reduces the number of shares reserved for
issuance under the 1981 Stock Program by the number of shares with respect to
which the SAR is exercised.
 
  AMENDMENT AND TERMINATION OF PROGRAM. The Board may amend the 1981 Stock
Program from time to time or terminate the 1981 Stock Program at any time, but
may not reduce the then existing amount of any participant's options or SARs or
adversely change the terms and conditions thereof without the participant's
consent. No amendment may without stockholder approval, (i) materially increase
the benefits accruing to participants, (ii) materially increase the number of
shares which may be issued, or (iii) materially modify the requirements as to
eligibility for participation in the 1981 Stock Program. The Plan of
Recapitalization will automatically terminate on December 8, 2001.
 
  FEDERAL INCOME TAX CONSEQUENCES. The Company has been advised by counsel that
the Federal income tax consequences to the participants in the 1981 Stock
Program and the affiliate of the Company employing them under the now
applicable provisions of the Internal Revenue Code and the regulations
thereunder are substantially as follows.
 
 
                                      146
<PAGE>
 
  With respect to NQSOs and SARs, an optionee is not deemed to receive any
income at the time an NQSO or SAR is granted nor is his employer entitled to a
deduction at that time. However, when any part of the NQSO or SAR is exercised
the optionee is deemed to have received ordinary income (i) in the case of an
NQSO, in an amount equal to the difference between the option price and the
fair market value of the shares acquired upon such exercise and (ii) in the
case of an SAR, in an amount equal to the sum of the fair market value of the
shares and any cash received. The optionee's employer is entitled to a tax
deduction in an amount equal to the amount of ordinary income realized by the
optionee.
 
  With respect to ISOs, an optionee is not deemed to receive any income at the
time an ISO is granted or exercised, and his employer is not entitled to any
deduction. If the optionee disposes of the stock prior to the expiration of the
holding period required by Section 422 of the Internal Revenue Code, he will
have ordinary income in the year of disposition equal to the excess of the
amount received for the shares over the option price, and his employer is
entitled to a tax deduction at such time in an amount equal to the amount of
ordinary income realized by the optionee. If the optionee disposes of the stock
after expiration of the holding period required by Section 422 of the Internal
Revenue Code, the excess of the amount received for the shares over the option
price will be taxed as long term capital gain and no deduction will be
available to the employer.
 
  Special rules apply in the case of individuals subject to Section 16(b) of
the Exchange Act. In particular, under current law any shares received pursuant
to the exercise of a stock option or SAR, absent an election by the optionee to
include in his income at the time of exercise the excess of the value of shares
received over the option price, are treated as restricted as to transferability
and subject to a substantial risk of forfeiture for a period of six months
after the date of grant of the option. Accordingly, the amount of ordinary
income recognized, and the amount of the employer's deduction, are determined
as of such later date.
 
  The Board of Directors recommends a vote FOR the approval of the amendments
to the 1981 Stock Program.
 
            APPROVAL OF AMENDMENTS TO THE 1988 RESTRICTED STOCK PLAN
 
  ON MARCH 25, 1994, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDED IN
CONNECTION WITH THE APPROVAL OF THE RECAPITALIZATION THAT THE STOCKHOLDERS VOTE
FOR APPROVAL OF AMENDMENTS (THE "1988 RESTRICTED STOCK PLAN AMENDMENTS") TO THE
1988 RESTRICTED STOCK PLAN (THE "1988 RESTRICTED STOCK PLAN") TO PRESERVE, TO
THE MAXIMUM EXTENT POSSIBLE, THE DEDUCTIBILITY BY THE COMPANY OF AMOUNTS
AWARDED UNDER THE PLAN.
 
  The full text of the 1988 Restricted Stock Plan Amendment is filed as an
exhibit to the Registration Statement. The following summary of the 1988
Restricted Stock Plan is qualified in its entirety by the full text of the 1988
Restricted Stock Plan and the 1988 Restricted Stock Plan Amendment.
 
  SHARES. A maximum of 500,000 Old Shares may be awarded under the 1988
Restricted Stock Plan. Upon consummation of the Plan of Recapitalization, the
Old Shares remaining to be issued under the 1988 Restricted Stock Plan will be
converted into New Shares. Shares awarded under the 1988 Restricted Stock Plan
(the "Restricted Stock") may only be treasury shares. Shares of Restricted
Stock that are forfeited under the 1988 Restricted Stock Plan may subsequently
be awarded to other participants under the 1988 Restricted Stock Plan.
   
  The closing price of the common stock on the NYSE on May 25, 1994 was $116
7/8.     
 
  PARTICIPATION. Restricted Stock may be awarded under the 1988 Restricted
Stock Plan to key employees, including officers, of the Corporation and its
subsidiaries. The 1988 Restricted Stock Plan currently imposes no limit on the
number of officers and other key employees to whom Restricted Stock may be
awarded or on the number of shares that may be granted to any individual. The
1988 Restricted Stock
 
                                      147
<PAGE>
 
   
Plan Amendments would limit the number of New Shares that may be awarded under
the 1988 Restricted Stock Plan to any individual during any two-year period to
30,000 (60,000 with respect to grants made to any new employee as a condition
of employment), subject to adjustment if additional shares become issuable to
the employee groups in accordance with the Plan of Recapitalization. See "THE
PLAN OF RECAPITALIZATION--Establishment of ESOPs--Additional Shares."     
   
  ADMINISTRATION. The 1988 Restricted Stock Plan is administered by the
Compensation Committee of the Board. Upon consummation of the Plan of
Recapitalization, the Plan will be administered by the Compensation
Administration Committee of the Board.     
 
  RESTRICTIONS. Restricted Stock is awarded under the 1988 Restricted Stock
Plan in the discretion of the Compensation Committee. All shares of stock
awarded pursuant to the 1988 Restricted Stock Plan (including any shares
received by the holders thereof as a result of stock dividends, stock splits or
any other forms of recapitalization) shall be subject to the restrictions
specified in the 1988 Restricted Stock Plan. Restricted Stock certificates
shall remain in the custody of the Company and shall bear a legend that such
Restricted Stock may not be sold or encumbered until all restrictions are
terminated or expire. Restrictions expire ten years after award unless the
Compensation Committee determines in its discretion to accelerate or terminate
the period of restriction. Restrictions expire upon a Change in Control, as
defined in the 1988 Restricted Stock Plan. In addition, the restrictions expire
if the Company is dissolved, or is not the surviving corporation in a merger or
consolidation, unless the surviving corporation agrees to exchange the
Restricted Stock for its shares having an equivalent value. Participants, as
owners of the awarded shares, shall have all other stockholder rights,
including the right to vote shares of Restricted Stock and to receive dividends
and other distributions, if any, during the restriction period. The 1988
Restricted Stock Plan Amendments would permit the Committee to provide that the
"Restricted Period" with respect to any Restricted Shares shall lapse based
upon the attainment by the Company of one or more target levels of pre-tax
income (as determined under generally accepted accounting principles but
without regard to any items (whether gains or losses) otherwise included
therein relating to (1) the ESOPs or the ESOP Trusts, (2) any event or
occurrence that the Committee determines to be either not directly related to
the operations of the Company or not within the reasonable control of the
Company's management, (3) the 1988 Restricted Stock Plan and (4) the Company's
Incentive Compensation Plan (as defined below)). Such target level(s) shall be
determined by the Compensation Committee on or before the allocation of such
Restricted Shares, shall relate to such period or periods of time as the
Compensation Committee shall prescribe and may provide that any period in which
such pre-tax income is less than zero may be disregarded.
 
  AMENDMENT. The 1988 Restricted Stock Plan may be amended, suspended or
terminated by the Board, provided that no such action shall increase the
maximum number of shares that may be awarded pursuant to the Plan of
Recapitalization, render any Compensation Committee member eligible to receive
Restricted Stock while a Compensation Committee member, or adversely affect
awards already made without the participant's consent.
 
  ADJUSTMENTS. In case of a stock split, stock dividend, merger, consolidation,
reorganization, recapitalization or other change in corporate structure of the
Company, appropriate adjustments will be made by the Compensation Committee in
the number and kind of shares subject to the 1988 Restricted Stock Plan.
 
  FEDERAL INCOME TAX CONSEQUENCES. No income will be recognized by a
participant upon receipt of any award of Restricted Stock, unless the
participant files an election with the IRS within 30 days of the award to
recognize such income. If the participant makes such an election, the Company
would be entitled to a deduction for payment of compensation, assuming
compliance with applicable withholding requirements, and the participant would
be required to report as ordinary income, the fair market value of the
Restricted Stock
 
                                      148
<PAGE>
 
on the award date. In the absence of such an election, the participant's income
and the Company's corresponding deduction are deferred until the restrictions
cease to apply, at which time the amount of the income and deduction would be
based on the fair market value of the shares at the time the restrictions cease
to apply.
 
  Unless the election referred to above is made, dividends received with
respect to Restricted Stock prior to the time the restrictions cease to apply
would be taxed as ordinary income to the participant and would be deductible by
the Company as payment of compensation, assuming compliance with applicable
withholding requirements. Dividends received with respect to shares after such
an election has been made or after the restrictions cease to apply would be
taxed as dividends to the participant and would not be deductible by the
Company.
 
           APPROVAL OF AMENDMENTS TO THE INCENTIVE COMPENSATION PLAN
 
  ON MARCH 25, 1994 THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDED IN
CONNECTION WITH THE APPROVAL OF THE RECLASSIFICATION THAT THE STOCKHOLDERS VOTE
FOR APPROVAL OF AMENDMENTS (THE "INCENTIVE PLAN AMENDMENT") TO THE COMPANY'S
INCENTIVE COMPENSATION PLAN (THE "INCENTIVE PLAN") TO PRESERVE, TO THE MAXIMUM
EXTENT POSSIBLE, THE DEDUCTIBILITY BY THE COMPANY OF AMOUNTS PAID THEREUNDER.
 
  The full text of the Incentive Compensation Amendment is filed as an exhibit
to the Registration Statement. The following summary of the Incentive
Compensation Plan is qualified in its entirety by the full text of the
Incentive Plan and the Incentive Plan Amendment.
 
  Key employees and officers of the Company and its subsidiaries are eligible
to participate in the Incentive Plan. The grant of awards and the size thereof
depends upon the degree to which the Company's financial targets, as approved
by the Compensation Committee, are reached or exceeded and the extent to which
individual performance objectives set by management (or by the Compensation
Committee in the case of the Company's CEO) are attained or exceeded.
Performance is measured annually and awards are vested in the year awarded.
Awards are paid in the year awarded.
   
  Pursuant to the Incentive Plan Amendment, awards under the Incentive Plan
with respect to any participant who is a "covered employee" (as defined in
Section 162(m)(3) of the Internal Revenue Code) with respect to the applicable
award year (i) may not exceed $900,000 and (ii) shall be determined by
reference to a formula which shall define the award by reference to the
attainment by the Company of one or more target levels of pre-tax income (as
determined under generally accepted accounting principles but without regard to
any items (whether gains or losses) otherwise included therein relating to (1)
the ESOPs or the ESOP Trusts, (2) any event or occurrence that the Compensation
Administration Committee determines to be either not directly related to the
operations of the Company or not within the reasonable control of the Company's
management, (3) the Incentive Plan and (4) the Company's 1988 Restricted Stock
Plan) for such award year. Such target level(s) and the formula referred to
above shall be determined by the Compensation Administration Committee prior to
the commencement of such award year (or at such later time as may be
permissible under Section 162(m) of the Internal Revenue Code). Notwithstanding
the foregoing, the Compensation Administration Committee may reduce the award
otherwise determined pursuant to such formula in its sole discretion.     
 
  The Incentive Plan Amendment further provides that payment of an award may be
deferred, pursuant to a prior election by a participant, to a period selected
by the participant. The Incentive Plan may be amended, modified or terminated
by the Board in its discretion.
 
  Amounts paid under the Incentive Plan should be taxable as ordinary income to
the participant and deductible by the Company, in each case, in the year in
which the amounts are paid.
 
  The Board of Directors recommends a vote FOR approval of the amendments to
the Incentive Plan.

                           DESCRIPTION OF SECURITIES
 
THE DEBENTURES
   
  The Series A Debentures and the Series B Debentures will be issued under an
Indenture dated as of July 1, 1991 between United, as issuer, and The Bank of
New York, as Trustee (the "Indenture Trustee") and an officers' certificate
that sets forth certain terms of the Debentures (collectively, the
"Indenture"). Copies of the Indenture and the related documentation have been
filed as an exhibit to the Registration Statement of which this Proxy
Statement/Prospectus is a part. The summary of terms of the Debentures
contained in this Proxy Statement/Prospectus does not purport to be complete
and is subject to, and is qualified in its entirety by, the provisions of the
Indenture, including the definitions therein of certain capitalized terms used
in this Proxy Statement/Prospectus. Where the summaries do not make a
distinction between the Series A Debentures and the Series B Debentures, such
summaries refer to either series. Whenever particular Sections or defined terms
of the Indenture are referred to herein, such sections or defined terms are
incorporated herein by reference.     
 
 General
   
  The Debentures will be issued only in fully registered form without coupons
in denominations of $100 principal amount and integral multiples thereof,
provided that if the Offerings are consummated, the Debentures may be issued in
denominations of $1,000 principal amount and integral multiples thereof.
Although United intends to apply to list the Debentures on the NYSE, there can
be no assurance that at or following the Effective Time the Debentures will be
listed on the NYSE or any other securities exchange or that any trading market
for the Debentures will develop. If the Debentures are listed on the NYSE, the
Debentures will trade on such exchange only in denominations of $1,000 and
integral multiples thereof.     
   
  The Indenture pursuant to which the Debentures will be issued does not limit
the aggregate principal amount of Debentures that may be issued in either
series. United has registered $449,802,200 aggregate principal amount of each
series of Debentures for distribution to holders of Old Shares in connection
with the Recapitalization if the Offerings are not consummated, based upon the
number of Fully Diluted Old Shares. See "THE PLAN OF RECAPITALIZATION--Terms
and Conditions--General." Of that amount, United expects that approximately
$382,071,900 aggregate principal amount of each series of Debentures will be
issued in respect of the Old Shares currently outstanding (including the
unvested restricted shares) and not more than approximately $67,730,300
aggregate principal of each series of Debentures will be issued in connection
with the exercise of Options and Convertible Company Securities. Many of the
Options and Convertible Company Securities are out of the money and are not
currently expected to be exercised. If market conditions change, Options and
Convertible Company Securities that are currently out of the money may be
exercised. Similarly, the number of Fully Diluted Old Shares presumes that the
Company uses the proceeds from the exercise of Options and Convertible Company
Securities to purchase Recapitalization Consideration. This assumption is meant
to mimic the effect of the "cashless exercise" feature of the Options. See "THE
PLAN OF RECAPITALIZATION--Establishment of ESOPs--Additional Shares." The
effect of the "cashless exercise" is to reduce the amount of the
Recapitalization Consideration required to be issued in connection with the
Recapitalization. Holders of Options and Convertible Company Securities may
elect not to use the "cashless exercise" feature. Accordingly, the aggregate
principal amount of each series of Debentures that is required to be issued in
connection with the exercise of Options and Convertible Company Securities may
exceed $67,730,300. As an alternative to issuing additional Debentures, if
conditions permit, the Company or United may attempt to acquire previously
issued Debentures in the market. At the present time, the Company and United
believe that the aggregate principal amount of Debentures that it has
registered will be sufficient for purposes of the Recapitalization, including
in connection with the exercise of Options and Convertible Company Securities,
although there can be no assurance that this will be the case.     
       
       
   
  The Indenture does not contain any covenants or provisions that provide
protection to the holder of Debentures in the event of a highly leveraged
transaction or a change of control.     
 
 
                                      150
<PAGE>
 
   
  The Series A Debentures will bear interest at a rate per annum that has been
fixed provisionally at 9.00%, and the Series B Debentures will bear interest at
a rate per annum that has been fixed provisionally at 9.70%. As provided in the
Plan of Recapitalization, the rates of interest proposed to be borne by the
Series A Debentures and the Series B Debentures may be adjusted in advance of
the Meeting to rates that would permit the Series A Debentures and the Series B
Debentures to trade at par, on a fully distributed basis, as of the date on
which such determination is made, although the interest rates to be borne by
the Debentures may not be adjusted above 10.125% in the case of the Series A
Debentures and 10.825% in the case of the Series B Debentures. The Company will
make a public announcement of the rates of interest to be borne by the Series A
Debentures and the Series B Debentures at least five days but not more than ten
days in advance of the Meeting. See "THE PLAN OF RECAPITALIZATION--Terms and
Conditions--Pricing the Securities." The underwriting agreements provide that
if the Offerings are consummated, the interest rates on the Debentures may be
adjusted to permit them to be sold at or closer to par, but if that is done,
the principal amount of the series of Debentures affected must be reduced so
that the aggregate amount of interest payable annually by United on the
Debentures will not exceed certain maximum limits. If the Offerings are not
consummated, the interest rates borne by the Debentures will be subject to the
caps. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--Pricing the
Securities.     
   
  The Plan of Recapitalization also provides that, at the request of the
Unions, either or both series of Debentures may be made redeemable prior to
their respective final stated maturity at the option of United. See "--
Redemption" below. Interest on the Debentures will be paid semi-annually
beginning in 1994 to holders of record on the record date for such payment. The
Series A Debentures will mature in 2004. The Series B Debentures will mature in
2014. Prior to the Effective Time, the Company will establish the semi-annual
interest payment dates, the specific final maturity dates and the maximum
aggregate principal amount of each series of Debenture. The Debentures will
bear interest from the date of their original issuance or the most recent
interest payment date from which interest has been paid.     
   
  The Debentures will be unsecured and unsubordinated obligations of United and
will rank on a parity with all other unsecured and unsubordinated indebtedness
of United. As of March 31, 1994 United had outstanding approximately $2.8
billion aggregate principal amount of indebtedness that will rank pari passu
with the Debentures offered hereby, of which approximately $1.8 billion was
secured and approximately $1.0 billion was unsecured. The Indenture does not
limit the right of United to incur additional senior indebtedness. As of March
31, 1994, senior indebtedness of United on a consolidated basis aggregated
approximately $3.7 billion.     
 
 Redemption
   
  The Debentures will not be subject to any sinking fund or other obligation of
United to redeem or retire the Debentures. The Debentures may not be called for
redemption prior to their respective final stated maturities. The Plan of
Recapitalization provides that either or both series of Debentures may be made
redeemable at the option of United prior to their respective final stated
maturities if the Unions so request not less than seven days prior to the
Announcement Date. See "THE PLAN OF RECAPITALIZATION--Terms and Conditions--
Pricing the Securities."     
 
 Payment, Registration, Transfer and Exchange
 
  Payments in respect of the Debentures will be made at the office or agency of
United maintained for that purpose as United may designate from time to time,
except that, at the option of United, interest payments, if any, on the
Debentures may be made by checks mailed by the Indenture Trustee to the holders
of Debentures entitled thereto at their registered addresses. (Sections 3.7(a)
and 9.2 of the Indenture.) Payment of any installment of interest on Debentures
will be made to the persons in whose names such Debentures are registered at
the close of business on the regular record date for such interest. (Sections
3.7(a) of the Indenture.)
 
 
                                      151
<PAGE>
 
   
  Debentures will be transferable or exchangeable at the office or agency of
United maintained for such purpose as designated by United from time to time.
(Sections 3.5 and 9.2 of the Indenture.) Debentures may be transferred or
exchanged without service charge, other than any tax or other governmental
charge imposed in connection therewith. (Section 3.5 of the Indenture.)     
 
 Consolidation, Merger or Sale by United
 
  The Indenture provides that United may merge or consolidate with or into any
other corporation or sell, convey, transfer or otherwise dispose of all or
substantially all of its assets to any person, firm or corporation, if (i)(a)
in the case of a merger or consolidation, United is the surviving corporation
or (b) in the case of a merger or consolidation where United is not the
surviving corporation and in the case of such a sale, conveyance or other
disposition, the successor or acquiring corporation is a corporation organized
and existing under the laws of the United States of America or a State thereof
and such corporation expressly assumes by supplemental indenture all the
obligations of United under the Debentures and the Indenture, (ii) immediately
after giving effect to such merger or consolidation, or such sale, conveyance,
transfer or other disposition, no Default or Event of Default has occurred and
is continuing and (iii) certain other conditions are met. In the event a
successor corporation assumes the obligations of United, such successor
corporation will succeed to and be substituted for United under the Indenture
and under the Debentures and all obligations of United will terminate. (Section
7.1 of the Indenture.)
 
 Events of Default, Notice and Certain Rights on Default
 
  The Indenture provides that, if an Event of Default occurs with respect to
the Debentures of either series and is continuing, the Indenture Trustee for
such series or the holders of at least 25% in aggregate principal amount of all
of the outstanding Debentures of that series, by written notice to United (and
to the Indenture Trustee for such series, if notice is given by such holders of
Debentures), may declare the principal of all the Debentures of that series to
be due and payable. (Section 5.2 of the Indenture.)
   
  Events of Default with respect to Debentures of either series are defined in
the Indenture as being: (i) default for 30 days in payment of interest on any
Debentures of that series when due, (ii) default for 10 days in payment of
principal, premium, if any, at its maturity or on redemption or otherwise, of
any Debentures of that series when due, (iii) default for 60 days after notice
to United by the Indenture Trustee for such series, or to United and the
Indenture Trustee by the holders of at least 25% in aggregate principal amount
of the Debentures of such series then outstanding, in the performance of any
other agreement in the Debentures of that series, in the Indenture or in any
supplemental indenture, (iv) default resulting in acceleration of other
indebtedness of United for borrowed money where the aggregate principal amount
so accelerated exceeds $100 million and such acceleration is not rescinded or
annulled within 10 days after the written notice thereof to United by the
Indenture Trustee or to United and the Indenture Trustee by the holders of at
least 25% in aggregate principal amount of the Debentures of such series then
outstanding, provided that such Event of Default will be cured or waived if the
default that resulted in the acceleration of such other indebtedness is cured
or waived, and (v) certain events of bankruptcy, insolvency or reorganization
of United. (Section 5.1 of the Indenture.)     
   
  The Indenture provides that the Indenture Trustee for either series of
Debentures will, within 90 days after the occurrence of a Default with respect
to Debentures of that series, give to the holder of the Debentures of that
series notice of all uncured Defaults known to it; provided that, except in the
case of default in payment on the Debentures of that series, the Indenture
Trustee may withhold the notice if and so long as a committee of its
responsible officers in good faith determines that withholding such notice is
in the interest of the holders of the Debentures of that series. (Section 6.6
of the Indenture.) "Default" means any event that is, or, after notice or
passage of time or both, would be, an Event of Default. (Section 1.1 of the
Indenture.)     
 
  The Indenture provides that the holders of a majority in aggregate principal
amount of the Debentures of each series affected (with each such series voting
as a class) may direct the time, method and place of

                                      152
<PAGE>
 
conducting any proceeding for any remedy available to the Indenture Trustee for
such series or exercising any trust or power conferred on such Indenture
Trustee. (Section 5.8 of the Indenture.)
 
  The Indenture includes a covenant that United will file annually with the
Indenture Trustee a certificate as to United's compliance with all conditions
and covenants of the Indenture. (Section 9.7 of the Indenture.)
 
  The holders of a majority in aggregate principal amount of either series of
Debentures by notice to the Indenture Trustee for such series may waive, on
behalf of the holders of all Debentures of such series, any past Default or
Event of Default with respect to that series and its consequences except a
Default or Event of Default in the payment of the principal of, premium, if
any, or interest on any Debenture and certain other defaults. (Section 5.7 of
the Indenture.)
 
 Modification of the Indenture
   
  The Indenture contains provisions permitting United and the Indenture Trustee
to enter into one or more supplemental indentures without the consent of the
holders of any of the Debentures (i) to evidence the succession of another
corporation to United and the assumption of the covenants of United by a
successor to United, (ii) to add to the covenants of United for the benefit of
either series of Debentures or surrender any right or power of United, (iii) to
add additional Events of Default with respect to any series, (iv) to secure the
Debentures, (v) to evidence and provide for successor Indenture Trustees, (vi)
to correct or supplement any inconsistent provisions or to make any other
provisions with respect to matters or questions arising under the Indenture,
provided that such action does not adversely affect the interests of any holder
of Debentures of any series issued under the Indenture, or (vii) to cure any
ambiguity or correct any mistake. (Section 8.1 of the Indenture.)     
 
  The Indenture also contains provisions permitting United and the Indenture
Trustee, with the consent of the holders of a majority in aggregate principal
amount of the outstanding Debentures of each series affected by a supplemental
indenture, to execute such supplemental indenture to add any provisions to or
to change or to eliminate any of the provisions of the Indenture or any
supplemental indenture or to modify the rights of the holders of Debentures of
such series, except that no such supplemental indenture may, without the
consent of the holder of each Debenture so affected, (i) change the time for
payment of principal or interest on any Debenture, (ii) reduce the principal
of, or any installment of interest on, any Debenture, (iii) reduce the amount
of premium, if any, payable upon the redemption of any Debenture, (iv) change
the coin or currency in which any Debenture or any premium or interest thereon
is payable, (v) impair the right to institute suit for the enforcement of any
payment on or with respect to any Debenture, (vi) reduce the percentage in
principal amount of the outstanding Debentures of any series the consent of
whose holders is required for modification or amendment of the Indenture or for
waiver of compliance with certain provisions of the Indenture or for waiver of
certain defaults, (vii) change the obligation of United to maintain an office
or agency in the places and for the purposes specified in the Indenture or
(viii) modify the provisions relating to waiver of certain defaults or any of
the foregoing provisions. (Section 8.2 of the Indenture.)
 
 Defeasance and Covenant Defeasance
 
  United may elect either (i) to defease and be discharged from any and all
obligations with respect to the Debentures of any series (except as described
below) ("defeasance") or (ii) to be released from its obligations with respect
to certain covenants applicable to the Debentures of any series ("covenant
defeasance"), upon the deposit with the Indenture Trustee for such series (or
other qualifying trustee), in trust for such purpose, of money and/or
Government Obligations that through the payment of principal and interest in
accordance with their terms will provide money in the amount sufficient to pay
the principal of, premium, if any, and interest on such Debentures to their
respective final stated maturity or redemption, as the case may be. Upon the
occurrence of a defeasance, United will be deemed to have paid and discharged
the entire indebtedness represented by such Debentures and to have satisfied
all of its other obligations under such Debentures (except for (i) the rights
of holders of such Debentures to receive, solely from the trust funds deposited
to
 
                                      153
<PAGE>
 
defease such Debentures, payments in respect of the principal of, premium, if
any, and interest on such Debentures when such payments are due and (ii)
certain other obligations as provided in the Indenture). Upon the occurrence of
a covenant defeasance, United will be released only from its obligations to
comply with certain covenants contained in the Indenture relating to such
Debentures, will continue to be obligated in all other respects under such
Debentures and will continue to be contingently liable with respect to the
payment of principal, premium, if any, and interest with respect to such
Debentures.
 
  The conditions to both defeasance and covenant defeasance are as follows: (i)
such defeasance or covenant defeasance must not result in a breach or violation
of, or constitute a Default or Event of Default under, the Indenture, or result
in a breach or violation of, or constitute a default under, any other material
agreement or instrument of United, (ii) certain bankruptcy related Defaults or
Events of Default with respect to United must not have occurred and be
continuing during the period commencing on the date of the deposit of the trust
funds to defease such Debentures and ending on the 91st day after such date,
(iii) United must deliver to the Indenture Trustee an Opinion of Counsel to the
effect that the holders of such Debentures will not recognize income, gain or
loss for Federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to Federal income tax on the same amounts and in
the same manner and at all the same times as would have been the case if such
defeasance or covenant defeasance had not occurred (such Opinion of Counsel, in
the case of defeasance, must refer to and be based upon a ruling of the IRS or
a change in applicable Federal income tax law occurring after the date of the
Indenture) and (iv) United must deliver to the Indenture Trustee an Officers'
Certificate and an Opinion of Counsel with respect to compliance with the
conditions precedent to such defeasance or covenant defeasance and with respect
to certain registration requirements under the Investment Company Act of 1940,
as amended. (Article 4 of the Indenture.) The Indenture requires that a
nationally recognized firm of independent public accountants deliver to the
Indenture Trustee a written certification as to the sufficiency of the trust
funds deposited for the defeasance or covenant defeasance of such Debentures.
The Indenture does not provide the holders of such Debentures with recourse
against such firm. In the event that Government Obligations deposited with the
Indenture Trustee for the defeasance of such Debentures decrease in value or
default subsequent to their being deposited, United will have no further
obligation, and the holders of such Debentures will have no additional recourse
against United, as a result of such decrease in value or default. As described
above, in the event of a covenant defeasance, United remains contingently
liable with respect to the payment of principal, premium, if any, and interest
with respect to such Debentures.
 
  United may exercise its defeasance option with respect to such Debentures
notwithstanding its prior exercise of its covenant defeasance option. If United
exercises its defeasance option, payment of such Debentures may not be
accelerated because of a Default or an Event of Default. If United exercises
its covenant defeasance option, payment of such Debentures may not be
accelerated by reason of a Default or an Event of Default with respect to the
covenants to which such covenant defeasance is applicable. However, if such
acceleration were to occur, the realizable value at the acceleration date of
the money and Government Obligations in the defeasance trust could be less than
the principal and interest then due on such Debentures, in that the required
deposit in the defeasance trust is based upon scheduled cash flow rather than
market value, which will vary depending upon interest rates and other factors.
 
 The Indenture Trustee
 
  The Bank of New York is the Indenture Trustee under the Indenture. United and
the Company also maintain banking and other commercial relationships with The
Bank of New York and its affiliates in the ordinary course of business and The
Bank of New York acts as trustee under several indentures for United and the
Company.
 
THE CAPITAL STOCK OF THE COMPANY
 
  As of the date of this Proxy Statement/Prospectus, the Company's current
Amended and Restated Certificate of Incorporation authorizes the issuance of
125,000,000 shares of Old Shares and 16,000,000 shares
 
                                      154

of preferred stock. As of May 11, 1994, there were outstanding (a) 24,571,077
Old Shares, (b) 6,000,000 shares of Series A Preferred Stock that were
convertible into 3,833,866 Old Shares, (c) Options to purchase an aggregate of
1,632,568 Old Shares, (d) $33,005,000 principal amount of Air Wis Convertible
Debentures that were convertible into 130,369 Old Shares and (e) rights to
purchase 245,710 shares of Junior Participating Preferred Stock. The Company
has designated 1,250,000 shares of a series of preferred stock as Junior
Participating Preferred Stock (as defined below), which are reserved for
issuance upon exercise of certain preferred share purchase rights associated
with each outstanding Old Share (the "Rights"), as described below.     
   
  Upon consummation of the Recapitalization, the authorized capital stock of
the Company will consist of (i) 100,000,000 New Shares, par value $0.01 per
share, (ii) 16,000,000 shares of serial preferred stock, without par value (the
"Serial Preferred Stock"), of which (a) 6,000,000 shares will be designated as
Series A Preferred Stock, (b) 50,000 shares will be designated Public Preferred
Stock, (c) 1,250,000 shares will be designated Junior Participating Preferred
Stock, (d) 50,000 will be designated as Series D Redeemable Preferred Stock and
(e) 50,000 shares will be designated Series E Redeemable Preferred Stock, (iii)
an aggregate of 50,000,000 shares will be allocated between shares designated
as Class 1 ESOP Preferred Stock, par value $0.01 per share, and shares
designated as Class 2 ESOP Preferred Stock, par value $0.01 per share, (iv)
11,500,000 shares of the Class P Preferred Stock, par value $0.01 per share,
(v) 9,300,000 shares of the Class M Preferred Stock, par value $0.01 per share,
(vi) 4,200,000 shares of the Class S Preferred Stock, par value $0.01 per
share, (ix) ten shares of the Class I Preferred Stock, par value $0.01 per
share, (x) one share of the Class Pilot MEC Preferred Stock, par value $0.01
per share, (xi) one share of the Class IAM Preferred Stock, par value $0.01 per
share and (xii) ten shares of the Class SAM Preferred Stock, par value $0.01
per share. The serial preferred stock not otherwise designated may be issued
from time to time in one or more series, without stockholder approval, with
such powers, preferences and relative, participating, optional or other special
rights, and qualifications, limitations, or restrictions thereof as may be
adopted by the Board of Directors or a duly authorized committee thereof.     
   
  Upon consummation of the Recapitalization, assuming that (i) none of the
Options is exercised, (ii) none of the Convertible Company Securities is
converted and (iii) none of the ESOP Preferred Stock or the Voting Preferred
Stock is converted, the outstanding capital stock of the Company will consist
of (a) 12,285,530 New Shares, (b) 6,000,000 shares of Series A Preferred Stock,
(c) 30,566,419 Depositary Preferred Shares representing 30,566.5 shares of
Public Preferred Stock, (d) the number of shares of ESOP Preferred Stock
referred to below, (e) three shares of Voting Preferred Stock and (f) nine
shares of Director Preferred Stock. Upon consummation of the Recapitalization
assuming that (I) all the Options are exercised, (II) all the converted and
(III) none of the ESOP Preferred Stock or Voting Preferred Stock is converted,
the outstanding capital stock of the Company will consist of (A) 15,083,939 New
Shares, (B) 37,528,842 Depositary Preferred Shares representing interests in
37,528.8 shares of Public Preferred Stock, (C) the number of shares of ESOP
Preferred Stock referred to below, (D) three shares of Voting Preferred Stock
and (E) nine shares of Director Preferred Stock. In either case, all the shares
of Redeemable Preferred Stock that are issued will be redeemed for cash;
Debentures and Depositary Preferred Shares immediately upon issuance. The Plan
of Recapitalization provides that at least 17,675,345 shares of ESOP Preferred
Stock will be transferred to the ESOPs over the 69 months following the
Effective Time, see "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--
General," and that under certain circumstances a greater number may be
transferred. See "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--
Additional Shares." Immediately after the Effective Time, a smaller number of
ESOP Preferred Stock, including both Class 1 ESOP Preferred Stock and Class 2
ESOP Preferred Stock will be outstanding. Some additional shares of ESOP
Preferred Stock will not be outstanding but will be recorded on the books of
the Company as Book-Entry Shares. See "THE PLAN OF RECAPITALIZATION--
Establishment of ESOPs--Sales of ESOP Preferred Stock."     
 
  Upon the consummation of the Recapitalization and prior to the Sunset, the
New Shares and the Voting Preferred Stock will vote together as a single class
with respect to all matters submitted to the vote of the
 
                                      155
<PAGE>
 
       
   
holders of common stock pursuant to law or as provided in the Restated
Certificate except with respect to (a) such matters upon which the DGCL
requires a separate class vote and (b) the election of the Public Directors,
whom the New Shares will elect separately as a class, and on whose election the
Voting Preferred Stock will not vote. Initially, the Voting Preferred Stock
will represent the right to cast 55% of the votes that may be cast by the New
Shares and the Voting Preferred Stock voting together as a single class (less a
number of votes that is equal to the number of New Shares that have been issued
upon conversion of the ESOP Preferred Stock and the Voting Preferred Stock that
are held in the ESOPs). Under certain circumstances, the voting power of the
Voting Preferred Stock may be increased so that it represents up to 63% of the
votes that may be cast by the New Shares and the Voting Preferred Stock voting
together as a single class (less a number of votes that is equal to the number
of New Shares that have been issued upon conversion of the ESOP Preferred Stock
and the Voting Preferred Stock and that are held in the ESOPs). See "THE PLAN
OF RECAPITALIZATION--Establishment of ESOPs--Additional Shares."     
 
  After the Sunset, the New Shares and the Voting Preferred Stock will continue
to vote together as a single class with respect to all matters submitted to the
vote of the holders of common stock pursuant to law or as provided in the
Restated Certificate except with respect to such matters upon which the DGCL
requires a separate class vote. After the Sunset, the Voting Preferred Stock
will represent the right to cast a number of votes that is equal to the number
of New Shares into which the ESOP Preferred Stock can be converted.
   
  Upon the consummation of the Recapitalization, (i) the Class Pilot MEC
Preferred Stock will elect the ALPA Director until the later of the Sunset or
the date that ALPA members cease to be employees of the Company, (ii) the Class
IAM Preferred Stock will elect the IAM Director until the later of the Sunset
or the date that IAM members cease to be employees of the Company, (iii) the
Class SAM Preferred Stock will elect the Salaried and Management Director until
the later of (x) the Sunset or (y) the earlier of the time when ALPA members or
IAM members cease to be employees of the Company, and (iv) the Class I
Preferred Stock will elect the Independent Directors until the Sunset.     
 
THE PUBLIC PREFERRED STOCK
   
  The summary of terms of the Public Preferred Stock contained in this Proxy
Statement/Prospectus does not purport to be complete and is subject to, and is
qualified in its entirety by, the provisions of the Restated Certificate that
will become effective in connection with the consummation of the
Recapitalization. A copy of the Restated Certificate is included elsewhere in
this Proxy Statement/Prospectus.     
 
 General
   
  As part of the Recapitalization, each outstanding Old Share will, without
further action on the part of the holder thereof, be reclassified and converted
into, among other things, Depositary Preferred Shares representing interests in
$31.10 liquidation preference of Public Preferred Stock. See "--The Depositary
Preferred Shares." As contemplated by the Plan of Recapitalization, the Company
has elected to issue Depositary Preferred Shares, each representing interests
in one one-thousandth of a share of Public Preferred Stock having a liquidation
preference of $25. When issued, the Public Preferred Stock will be validly
issued, fully paid and nonassessable. The holders of the Public Preferred Stock
will not have any preemptive rights with respect to any shares of capital stock
of the Company or any other securities of the Company convertible into or
carrying rights or options to purchase any such shares. The Public Preferred
Stock will not be subject to any sinking fund or other obligation of the
Company to redeem or retire the Public Preferred Stock. Unless redeemed by the
Company, the Public Preferred Stock will have perpetual maturity.     
   
  The Company has registered under the Securities Act 35,984,175 Depositary
Preferred Shares representing interests in $899,604,375 aggregate liquidation
preference of the Public Preferred Stock for distribution to holders of Old
Shares in connection with this Recapitalization if the Offerings are not
consummated, based upon the number of Fully Diluted Old Shares. See "THE PLAN
OF RECAPITALIZATION--Terms and Conditions--General." Of that amount, the
Company expects that     
 
                                      156
<PAGE>
 
   
approximately 30,565,751 Depositary Shares representing interests in
$764,143,775 aggregate liquidation preference of the Public Preferred Stock
will be issued in respect of the Old Shares currently outstanding (including
the unvested restricted shares) and approximately 5,418,424 Depositary
Preferred Shares representing interests in $135,460,600 aggregate liquidation
preference of the Public Preferred Stock are expected to be issued in
connection with the exercise of Options and Convertible Company Securities.
Many of the Options and Convertible Company Securities are out of the money and
are not currently expected to be exercised. If market conditions change,
Options and Convertible Company Securities that are currently out of the money
may be exercised. Similarly, the number of Fully Diluted Old Shares presumes
that the Company uses the proceeds from the exercise of Options and Convertible
Company Securities to purchase Recapitalization Consideration. This assumption
is meant to mimic the effect of the "cashless exercise" feature of the Options.
See "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--Additional Shares."
The effect of the "cashless exercise" is to reduce the amount of the
Recapitalization Consideration required to be issued in connection with the
Recapitalization. Holders of Options and Convertible Company Securities may
elect not to use the "cashless exercise" feature. Accordingly, the number of
Depositary Preferred Shares and the aggregate liquidation value of the Public
Preferred Stock that are required to be issued in connection with the exercise
of Options and Convertible Company Securities may exceed 5,418,424 Depositary
Preferred Shares and $135,460,600 aggregate liquidation value. As an
alternative to issuing additional Depositary Preferred Shares of Public
Preferred Stock, if conditions permit, the Company may attempt to acquire
previously issued Depositary Preferred Shares in the market. The terms of the
Restated Certificate and the Deposit Agreement (as defined below) would not
prevent issuance of Depositary Preferred Shares or shares of Public Preferred
Stock in excess of the number already registered. At the present time, although
there can be no assurance, the Company believes that the number of Depositary
Preferred Shares and the aggregate liquidation value of the Public Preferred
Stock that it has registered will be sufficient for purposes of the
Recapitalization, including in connection with the exercise of Options and
Convertible Company Securities. As contemplated by the Plan of
Recapitalization, the Company has elected to issue Depositary Shares, each
representing interests in one one-thousandth of a share of Public Preferred
Stock, which is the equivalent of $25 liquidation preference.     
       
       
 Ranking
   
  The Public Preferred Stock will rank on a parity with the Series A Preferred
Stock and the Redeemable Preferred Stock and will rank senior to the New
Shares, the ESOP Preferred Stock, the Voting Preferred Stock, the Director
Preferred Stock and any shares of Junior Participating Preferred Stock issued
pursuant to the Rights with respect to payment of dividends and amounts payable
upon liquidation, dissolution or winding up.     
   
  While any shares of Public Preferred Stock are outstanding, the Company may
not authorize the creation or issue of any class or series of stock that ranks
senior to the Public Preferred Stock as to dividends or upon liquidation,
dissolution or winding up without the consent of the holders of 66 2/3% of the
outstanding shares of Public Preferred Stock. The Company may create additional
classes or series of preferred stock or authorize, or increase the authorized
amount of, any shares of any class or series of preferred stock ranking on a
parity with or junior to the Public Preferred Stock without the consent of any
holder of Public Preferred Stock. See "--Voting Rights" below.     
 
 Dividends
   
  Holders of shares of Public Preferred Stock will be entitled to receive,
when, as and if declared by the Board of the Company out of assets of the
Company legally available therefor, cumulative cash dividends at a rate per
annum that has been fixed provisionally at 10.25% of the $25,000 liquidation
preference thereof (or $2,526.50 per share) per annum. As provided in the Plan
of Recapitalization, the dividend rate proposed to be borne by the Public
Preferred Stock may be adjusted in advance of the Meeting to a rate that would
permit the Public Preferred Stock to trade at par, on a fully distributed
basis, as of the date such     
 
                                      157
<PAGE>
 
   
determination is made, although the dividend rate to be borne by the Public
Preferred Stock may not be adjusted above 11.375%. The Company will make a
public announcement of the revised dividend rate at least five days but not
more than ten days in advance of the Meeting. See "THE PLAN OF
RECAPITALIZATION--Terms and Conditions--Pricing the Securities." The
underwriting agreements will provide that if the Offerings are consummated, the
dividend rate on the Public Preferred Stock may be adjusted to permit the
Depositary Preferred Shares to be sold at or closer to par, but if that is
done, the number of Depositary interests in the Public Preferred Stock must be
reduced so that the aggregate amount of dividends payable annually by the
Company on the Public Preferred Stock will not exceed certain maximum limits.
If the Offerings are not consummated, the dividend rate borne by the Public
Preferred Stock will be subject to the cap. See "THE PLAN OF RECAPITALIZATION--
Terms and Conditions--Pricing the Securities."     
       
   
  Dividends on the Public Preferred Stock will be payable quarterly in arrears
on February 1, May 1, August 1 and November 1 of each year, commencing on the
first dividend payment date that follows the Effective Time, (and, in the case
of any accrued but unpaid dividends, at such additional times and for such
interim periods, if any, as determined by the Board of Directors), at such
annual rate, provided that if the Offerings are consummated, the regular
dividend payment dates may be as determined by the Company after consultation
with the underwriters. Each such dividend will be payable to holders of record
as they appear on the stock records of the Company at the close of business on
such record dates, which will not be more than 60 days or less than 10 days
preceding the payment dates corresponding thereto, as may be fixed by the Board
of Directors of the Company or a duly authorized committee thereof. Dividends
will accrue from the date of the original issuance of the Public Preferred
Stock (the "Issue Date"). Dividends will be cumulative from such date, whether
or not in any dividend period or periods there are assets of the Company
legally available for the payment of such dividends.     
   
  Each share of Public Preferred Stock issued after the Issue Date (whether
issued upon transfer of or in exchange for an outstanding share of Public
Preferred Stock or issued for any other reason) will be entitled to receive,
when, as and if declared by the Board, dividends with respect to each dividend
period, starting with the Issue Date, for which full dividends have not been
paid prior to the date upon which such share of Public Preferred Stock was
issued. Any share of Public Preferred Stock that is issued after the record
date with respect to any dividend payment and before such dividend is paid will
not be entitled to receive the dividend paid to holders of Public Preferred
Stock as of such record date.     
   
  The regular quarterly dividend payment dates with respect to Public Preferred
Stock coincide with the regular dividend payment dates on the Series A
Preferred Stock, and two of the dividend payment dates with respect to the
Public Preferred Stock will coincide with the regular semi-annual interest
payment dates on the Debentures unless the Offerings are consummated, in which
case such payments need not coincide. The Plan of Recapitalization provides
that, unless the Offerings are consummated, the Company will use the same
record date with respect to regular quarterly dividend payments on the Public
Preferred Stock and the Series A Preferred Stock. It also provides that the
Company will use the same record date with respect to the Public Preferred
Stock, the Series A Preferred Stock and the Debentures when the regular
dividend payment dates coincide with the regular interest payment date.     
 
  Accumulations of dividends on shares of Public Preferred Stock will not bear
interest. Dividends payable on the Public Preferred Stock for any period
greater or less than a full dividend period will be computed on the basis of a
360-day year consisting of twelve 30-day months. Dividends payable on the
Public Preferred Stock for each full dividend period will be computed by
dividing the annual dividend rate by four.
 
  Except as provided in the next sentence, no dividend will be declared or paid
on any Parity Stock (as defined below) unless full cumulative dividends have
been paid on the Public Preferred Stock for all prior dividend periods. If
accrued dividends on the Public Preferred Stock for all prior dividend periods
have not been paid in full, then any dividend declared on the Public Preferred
Stock for any dividend period and on
 
                                      158
<PAGE>
 
any Parity Stock will be declared ratably in proportion to accrued and unpaid
dividends on the Public Preferred Stock and such Parity Stock.
   
  The Company will not (i) declare, pay or set apart funds for the payment of
any dividend or other distribution with respect to any Junior Stock (as defined
below) or (ii) redeem, purchase or otherwise acquire for consideration any
Junior Stock or Parity Stock through a sinking fund or otherwise (except by
conversion into or exchange for shares of Junior Stock and other than a
redemption or purchase or other acquisition of New Shares made for purposes of
an employee incentive or benefit plan of the Company or any subsidiary), unless
all accrued and unpaid dividends with respect to the Public Preferred Stock and
any Parity Stock at the time such dividends or other distributions payable or
such redemption, purchase or acquisition is to occur have been paid or funds
have been set apart for payment of such dividends.     
 
  For purposes of the description of the Public Preferred Stock, (i) the term
"dividend" does not include dividends payable solely in shares of Junior Stock
on Junior Stock, or in options, warrants or rights to holders of Junior Stock
to subscribe for or purchase any Junior Stock, (ii) the term "Parity Stock"
means any other class or series of preferred stock ranking on a parity with the
Public Preferred Stock as to the payment of dividends and amounts payable upon
liquidation, dissolution or winding up and (iii) the term "Junior Stock" means
the New Shares, the ESOP Preferred Stock, the Voting Preferred Stock, the
Director Preferred Stock, any shares of Junior Participating Preferred Stock
issued pursuant to the Rights and any other class or series of capital stock of
the Company now or hereafter issued and outstanding that ranks junior as to the
payment of dividends or amounts payable upon liquidation, dissolution or
winding up to the Public Preferred Stock.
 
 Redemption
   
  The Public Preferred Stock is not redeemable prior to the fifth anniversary
of the Issue Date. On and after such date, the Public Preferred Stock is
redeemable at the option of the Company, in whole or in part, at the redemption
price of $25,000 per share, plus, in each case, all dividends accrued and
unpaid on the Public Preferred Stock up to the date fixed for redemption, upon
giving notice as provided below.     
 
  If fewer than all of the outstanding shares of Public Preferred Stock are to
be redeemed, the shares to be redeemed will be determined pro rata or by lot or
in such other manner as is prescribed by the Company's Board.
 
  At least 30 days but not more than 60 days prior to the date fixed for the
redemption of the Public Preferred Stock, a written notice will be mailed to
each holder of record of Public Preferred Stock to be redeemed, notifying such
holder of the Company's election to redeem such shares, stating the date fixed
for redemption thereof and calling upon such holder to surrender to the Company
on the redemption date at the place designated in such notice the certificate
or certificates representing the number of shares specified therein. On or
after the redemption date, each holder of Public Preferred Stock to be redeemed
must present and surrender his certificate or certificates for such shares to
the Company at the place designated in such notice and thereupon the redemption
price of such shares will be paid to or on the order of the person whose name
appears on such certificate or certificates as the owner thereof and each
surrendered certificate will be canceled. Should fewer than all the shares
represented by any such certificate be redeemed, a new certificate will be
issued representing the shares not redeemed.
 
  From and after the redemption date (unless the Company defaults in payment of
the redemption price), all dividends on the shares of Public Preferred Stock
designated for redemption in such notice will cease to accrue, and all rights
of the holders thereof as stockholders of the Company, except the right to
receive the redemption price thereof (including all accrued and unpaid
dividends up to the redemption date), will cease and terminate. Such shares may
not thereafter be transferred (except with the consent of the Company) on the
Company's books, and such shares may not be deemed to be outstanding for any
purpose whatsoever. On the redemption date, the Company must pay any accrued
and unpaid dividends in arrears for any dividend period ending on or prior to
the redemption date. In the case of a redemption date falling after a dividend
 
                                      159
<PAGE>
 
payment record date and prior to the related payment date, the holders of
Public Preferred Stock at the close of business on such record date will be
entitled to receive the dividend payable on such shares on the corresponding
dividend payment date, notwithstanding the redemption of such shares following
such dividend payment record date. Except as provided for in the preceding
sentences, no payment or allowance will be made for accrued dividends on any
shares of Public Preferred Stock called for redemption.
 
  At its election, the Company, prior to the redemption date, may deposit the
redemption price of the shares of Public Preferred Stock so called for
redemption in trust for the holders thereof with a bank or trust company, in
which case such notice to holders of the shares of Public Preferred Stock to be
redeemed will (i) state the date of such deposit, (ii) specify the office of
such bank or trust company as the place of payment of the redemption price and
(iii) call upon such holders to surrender the certificates representing such
shares at such place on or after the date fixed in such redemption notice
(which may not be later than the redemption date), against payment of the
redemption price (including all accrued and unpaid dividends up to the
redemption date). Any moneys so deposited which remain unclaimed by the holders
of Public Preferred Stock at the end of two years after the redemption date
will be returned by such bank or trust company to the Company.
 
 Liquidation Preference
   
  The holders of shares of Public Preferred Stock will be entitled to receive,
in the event of any liquidation, dissolution or winding up of the Company,
$25,000 per share plus an amount per share equal to all dividends (whether or
not earned or declared) accrued and unpaid thereon to the date of final
distribution to such holders (for purposes of the description of the Public
Preferred Stock, the "Liquidation Preference"), and no more.     
   
  Until the holders of the Public Preferred Stock have been paid the
Liquidation Preference in full, no payment will be made to any holder of Junior
Stock upon the liquidation, dissolution or winding up of the Company. If, upon
any liquidation, dissolution or winding up of the Company, the assets of the
Company, or proceeds thereof, distributable among the holders of the shares of
Public Preferred Stock are insufficient to pay in full the Liquidation
Preference and the liquidation preference with respect to any other shares of
Parity Stock, then such assets, or the proceeds thereof, will be distributed
among the holders of shares of Public Preferred Stock and any such Parity Stock
ratably in accordance with the respective amounts that would be payable on such
shares of Public Preferred Stock and any such Parity Stock if all amounts
payable thereon were paid in full. Neither a consolidation or merger of the
Company with another corporation nor a sale, lease or transfer of all or
substantially all of the Company's assets will be considered a liquidation,
dissolution or winding up, voluntary or involuntary, of the Company.     
 
 Voting Rights
   
  Except as indicated below, or except as otherwise from time to time required
by applicable law, the holders of shares of Public Preferred Stock will not
have any voting rights, and their consent will not be required for taking any
corporate action. When and if the holders of the Public Preferred Stock are
entitled to vote, each share will be entitled to 1,000 votes.     
   
  If the equivalent of six quarterly dividends payable on the Public Preferred
Stock have not been declared and paid or set apart for payment, whether or not
consecutive, the number of directors of the Company will be increased by two
and the holders of all Public Preferred Stock and any other series of Serial
Preferred Stock in respect of which such a default exists, voting as a class
without regard to series, will be entitled to elect two additional directors at
the next annual meeting and each subsequent meeting, until all cumulative
dividends have been paid in full or set apart for payment.     
 
  The affirmative vote or consent of the holders of 66 2/3% of the outstanding
shares of the Public Preferred Stock will be required for any amendment of the
Restated Certificate that alters or changes the powers,
 
                                      160
<PAGE>
 
preferences, privileges or rights of the Public Preferred Stock so as to
materially adversely affect the holders thereof. The affirmative vote or
consent of the holders of shares representing 66 2/3% of the outstanding shares
of the Public Preferred Stock will be required to authorize the creation or
issue of, or reclassify any authorized stock of the Company into, or issue or
authorize any obligation or security convertible into or evidencing a right to
purchase, any additional class or series of stock ranking senior to the Public
Preferred Stock.
 
  Except as required by law, the holders of Public Preferred Stock will not be
entitled to vote on any merger or consolidation involving the Company or a sale
of all or substantially all of the assets of the Company.
   
DEPOSITARY PREFERRED SHARES     
       
   
  The Depositary Preferred Shares will be issued under a Deposit Agreement (the
"Deposit Agreement") between the Company and First Chicago Trust Company of New
York, as the Depositary (the "Depositary"). A copy of the Deposit Agreement has
been filed as an exhibit to the Registration Statement of which this Proxy
Statement/Prospectus is a part. The summary of terms of the Depositary
Preferred Shares, the Depositary Receipts (as defined below) and the Deposit
Agreement contained in this Proxy Statement/Prospectus does not purport to be
complete and is subject to, and is qualified in its entirety by, the provisions
of the Deposit Agreement and the form of Depositary Receipt attached thereto,
including the definitions therein of certain capitalized terms used in this
Proxy Statement/Prospectus.     
   
 General     
   
  The Company will issue receipts for fractional interests ("Depositary
Preferred Shares" or "Depositary Shares") in the shares of the Public Preferred
Stock rather than full shares of the Public Preferred Stock. Each Depositary
Preferred Share will represent an interest in one one-thousandth of a share of
the Public Preferred Stock (the equivalent of $25 liquidation preference of
Public Preferred Stock).     
   
  The shares of the Public Preferred Stock represented by Depositary Preferred
Shares will be deposited under the Deposit Agreement. Subject to the terms of
the Deposit Agreement, each owner of a Depositary Preferred Share will be
entitled, in proportion to the applicable interest in a share of the Public
Preferred Stock represented by such Depositary Preferred Share, to all the
rights and preferences of the interest in shares of the Public Preferred Stock
represented thereby (including dividend, voting, redemption and liquidation
rights).     
   
  Although the Company intends to apply to list the Depositary Preferred Shares
on the NYSE, there can be no assurance that at or following the Effective Time
the Depositary Preferred Shares will be listed on the NYSE or any other
securities exchange or that any trading market for the Depositary Preferred
Shares will develop.     
   
 Dividends and Other Distributions     
   
  The Depositary will distribute all cash dividends or other cash distributions
received in respect of the shares of the Public Preferred Stock to the record
holders of Depositary Preferred Shares relating to the Public Preferred Stock
in proportion to the numbers of such Depositary Preferred Shares owned by such
holders.     
   
  In the event of a distribution other than in cash, the Depositary will
distribute property received by it to the record holders of Depositary
Preferred Shares in an equitable manner, unless the Depositary determines that
it is not feasible to make such distribution, in which case the Depositary may
sell such property and distribute the net proceeds from such sale to such
holders.     
   
 Redemption of Depositary Preferred Shares     
   
  If the shares of the Public Preferred Stock represented by Depositary
Preferred Shares are subject to redemption, the Depositary Preferred Shares
will be redeemed from the proceeds received by the Depositary     
 
                                      161
<PAGE>
 
   
resulting from the redemption, in whole or in part, of such shares of the
Public Preferred Stock held by the Depositary. The redemption price per
Depositary Preferred Share will be equal to the applicable fraction of the
redemption price per share payable with respect to such shares of the Public
Preferred Stock. Whenever the Company redeems shares of the Public Preferred
Stock held by the Depositary, the Depositary will redeem as of the same
redemption date the number of Depositary Preferred Shares representing shares
of the Public Preferred Stock so redeemed. If fewer than all the Depositary
Preferred Shares are to be redeemed, the Depositary Preferred Shares to be
redeemed will be selected by lot, pro rata or by any other equitable method as
may be determined by the Depositary.     
   
 Voting the Shares of the Public Preferred Stock     
   
  Upon receipt of notice of any meeting at which the holders of the Public
Preferred Stock are entitled to vote, the Depositary will mail the information
contained in such notice of meeting to the record holders of the Depositary
Preferred Shares relating to such shares of the Public Preferred Stock. Each
record holder of such Depositary Preferred Shares on the record date (which
will be the same date as the record date for the shares of the Public Preferred
Stock) will be entitled to instruct the Depositary as to the exercise of the
voting rights pertaining to the fraction of the shares of the Public Preferred
Stock represented by such holder's Depositary Shares. The Depositary will
endeavor, insofar as practicable, to vote the shares of the Public Preferred
Stock represented by such Depositary Preferred Shares in accordance with such
instructions, and the Company will agree to take all reasonable action that may
be deemed necessary by the Depositary in order to enable the Depositary to do
so. The Depositary will abstain from voting the shares of the Public Preferred
Stock to the extent it does not receive specific instructions from the holder
of Depositary Preferred Shares representing such shares of the Public Preferred
Stock.     
   
 Amendment and Termination of the Deposit Agreement     
   
  The form of Depositary Receipt evidencing the Depositary Preferred Shares and
any provision of the Deposit Agreement may at any time be amended by agreement
between the Company and the Depositary. However, any amendment that materially
and adversely alters the rights of the holders of Depositary Shares will not be
effective unless the holders of at least a majority of the Depositary Preferred
Shares then outstanding approve such amendment. The Deposit Agreement will only
terminate if (i) all outstanding Depositary Preferred Shares have been redeemed
or (ii) there has been a final distribution in respect of the shares of the
Public Preferred Stock in connection with any liquidation, dissolution or
winding up of the Company and such distribution has been distributed to the
holders of the Depositary Receipts.     
   
 Charges of Depositary     
   
  The Company will pay all transfer and other taxes and governmental charges
arising solely from the existence of the depositary arrangements. The Company
will pay charges of the Depositary in connection with the initial deposit of
the shares of the Public Preferred Stock and issuance of Depositary Receipts,
all withdrawals of shares of the Public Preferred Stock by owners of Depositary
Preferred Shares and any redemption of the shares of the Public Preferred
Stock. Holders of Depositary Receipts will pay other transfer and other taxes
and governmental charges and such other charges as are expressly provided in
the Deposit Agreement to be for their accounts.     
   
 Resignation and Removal of Depositary     
   
  The Depositary may resign at any time by delivering to the Company notice of
its election to do so, and the Company may at any time remove the Depositary,
any such resignation or removal to take effect upon the appointment of a
successor Depositary and its acceptance of such appointment. Such successor
Depositary must be appointed within 60 days after delivery of the notice of
resignation or removal and must be a bank or trust company having its principal
office in the United States and having a combined capital and surplus of at
least $50,000,000.     
 
 
                                      162
<PAGE>
 
   
 Miscellaneous     
   
  The Depositary will forward all reports and communications from the Company
that are delivered to the Depositary and that the Company is required or
otherwise determines to furnish to the holders of the Depositary Preferred
Shares.     
   
  Neither the Depositary nor the Company will be liable under the Deposit
Agreement to holders of Depositary Receipts other than for its gross
negligence, willful misconduct or bad faith. Neither the Company nor the
Depositary will be obligated to prosecute or defend any legal proceeding in
respect of any Depositary Preferred Shares or Public Preferred Stock unless
satisfactory indemnity is furnished. The Company and the Depositary may rely
upon written advice of counsel or accountants, or upon information provided by
persons presenting shares of the Public Preferred Stock for deposit, holders
of Depositary Receipts or other persons believed to be competent and on
documents believed to be genuine.     
 
THE REDEEMABLE PREFERRED STOCK
   
  The summary of terms of the Redeemable Preferred Stock contained in this
Proxy Statement/Prospectus Section does not purport to be complete and is
subject to, and is qualified in its entirety by, the provisions of the
Restated Certificate that will become effective in connection with the
consummation of the Recapitalization. A copy of the Restated Certificate is
included elsewhere in this Proxy Statement/Prospectus.     
 
 General
 
  The Redeemable Preferred Stock will be issued in units equal to one one-
thousandth of a share, and as part of the Recapitalization, each outstanding
Old Share will, without further action on the part of the holder thereof, be
reclassified and converted into, among other things, one one-thousandth of a
share of Redeemable Preferred Stock. When issued, the Redeemable Preferred
Stock will be validly issued, fully paid and nonassessable.
   
  The Redeemable Preferred Stock consists of two series of Preferred Stock
that are identical except that the holder of Series E Redeemable Preferred
Stock will receive cash upon the redemption of the stock or the liquidation of
the Company and the holder of Series D Redeemable Preferred Stock will receive
cash, Debentures and interests in Public Preferred Stock that will be
represented by Depositary Shares upon the redemption of the stock or the
liquidation of the Company. Where the summaries do not make a distinction
between the Series E Redeemable Preferred Stock and the Series D Redeemable
Preferred Stock, such summaries refer to either series.     
   
  Shares of only one of the series of Redeemable Preferred Stock will be
issued. If the Offerings are consummated, the Series E Redeemable Preferred
Stock will be issued, and if the Offerings are not consummated, the Series D
Redeemable Preferred Stock will be issued.     
 
 Redemption
   
  Each one one-thousandth of a share of Series E Redeemable Preferred Stock
will be redeemable, and immediately upon the issuance thereof the Company will
redeem each one one-thousandth of a share of Series E Redeemable Preferred
Stock that is issued, for cash in an amount equal to the sum of (i) $25.80,
(ii) the proceeds (without deducting the underwriting discount or other costs)
from the sale by United of $15.55 principal amount of its Series A Debentures
and $15.55 principal amount of its Series B Debentures pursuant to the United
Debt Offering and (iii) the proceeds (without deducting the underwriting
discount or other costs) from the sale by the Company of Depositary Preferred
Shares representing interests in $31.10 liquidation preference of its Series B
Preferred Stock pursuant to the UAL Preferred Offering.     
   
  Each one one-thousandth of a share of Series D Redeemable Preferred Stock
will be redeemable, and immediately upon the issuance thereof the Company will
redeem each one one-thousandth of a share of Series     
 
                                      163
<PAGE>
 
   
D Redeemable Preferred Stock that is issued, for (i) $25.80 in cash, (ii)
$15.55 principal amount of Series A Debentures, (iii) $15.55 principal amount
of Series B Debentures and (iv) Depositary Preferred Shares representing
interests in $31.10 liquidation preference of Public Preferred Stock.
Fractional shares of Redeemable Preferred Stock will be issued, and immediately
redeemed, in the Recapitalization. The Series A Debentures and Series B
Debentures will be issued to holders of Series D Redeemable Preferred Stock
only in principal amounts equal to integral multiples of $100, and Depositary
Preferred Shares will be issued only to represent interests in $25 liquidation
preference of the Series B Preferred Stock or integral multiples thereof. In
lieu of issuing Series A Debentures and Series B Debentures other than in
integral multiples of $100, and Depositary Preferred Shares other than in
multiples of $25, the Company will pay to each holder of Series D Redeemable
Preferred Stock an amount of cash that is equal to the portion of the Series A
Debentures and Series B Debentures, or Depositary Preferred Shares to which
such holder would be entitled but for the immediately preceding sentence, that
is not an integral multiple of $100 or $25, as the case may be. See "THE PLAN
OF RECAPITALIZATION--Terms and Conditions--Payment for Shares."     
   
  At the time of the redemption, the rights of all holders of Redeemable
Preferred Stock will cease as stockholders of the Company with respect to such
shares (except the right to receive the Redemption Consideration as provided
above), and the person entitled to receive the Redemption Consideration upon
the redemption will be treated for all purposes as the owner of such Redemption
Consideration as of the date of such redemption.     
 
 Ranking
 
  The Redeemable Preferred Stock will rank on a parity with the Series A
Preferred Stock and the Public Preferred Stock and will rank senior to the New
Shares, the ESOP Preferred Stock, the Voting Preferred Stock, the Director
Preferred Stock and any shares of Junior Participating Preferred Stock issued
pursuant to the Rights with respect to amounts payable upon liquidation,
dissolution or winding up.
 
 Dividends
 
  Holders of shares of Redeemable Preferred Stock will not be entitled to
receive any dividends.
 
 Liquidation Preference
   
  The holder of a share of Series E Redeemable Preferred Stock, or any fraction
thereof, will be entitled to receive, in the event of any liquidation,
dissolution or winding up of the Company, for each one one-thousandth of a
share of Series E Redeemable Preferred Stock, cash equal to the sum of (A)
$25.80, (B) the proceeds (without deducting the underwriting discount and other
costs) from the sale by United of $15.55 face amount of its Series A Debentures
and $15.55 face amount of its Series B Debentures and (C) the proceeds (without
deducting the underwriting discount and other costs) from the sale by the
Company of Depositary Preferred Shares representing interests in $31.10
liquidation preference of its Public Preferred Stock (for purposes of the
description of the Series E Redeemable Preferred Stock, the "Liquidation
Preference"), and no more.     
   
  The holder of a share of Series D Redeemable Preferred Stock, or any fraction
thereof, will be entitled to receive, in the event of any liquidation,
dissolution or winding up of the Company, for each one one-thousandth of a
share of Series D Redeemable Preferred Stock, $25.80 in cash, $15.55 principal
amount of Series A Debentures, $15.55 principal amount of Series B Debentures
and Depositary Preferred Shares representing interests in $31.10 liquidation
preference of Public Preferred Stock, (for purposes of the description of the
Series D Redeemable Preferred Stock, the "Liquidation Preference") and no more.
    
  Until the holders of the Redeemable Preferred Stock have been paid the
Liquidation Preference in full, no payment will be made to any holder of Junior
Stock (as defined below) upon the liquidation, dissolution or winding up of the
Company. If, upon any liquidation, dissolution or winding up of the Company,
the
 
                                      164
<PAGE>
 
   
assets of the Company, or proceeds thereof, distributable among the holders of
the shares of Redeemable Preferred Stock are insufficient to pay in full the
Liquidation Preference and the liquidation preference with respect to any other
shares of Parity Stock (as defined below), then such assets, or the proceeds
thereof, will be distributed among the holders of shares of Redeemable
Preferred Stock and any such Parity Stock ratably in accordance with the
respective amounts that would be payable on such shares of Redeemable Preferred
Stock and any such Parity Stock if all amounts payable thereon were paid in
full. Neither a consolidation or merger of the Company with another corporation
nor a sale, lease or transfer of all or substantially all of the Company's
assets will be considered a liquidation, dissolution or winding up, voluntary
or involuntary, of the Company.     
 
  For purposes of the description of the Redeemable Preferred Stock, (i) the
term "Parity Stock" means any other class or series of preferred stock ranking
on a parity with the Redeemable Preferred Stock as to the payment of dividends
and amounts payable upon liquidation, dissolution or winding up and (ii) the
term "Junior Stock" means the New Shares, the ESOP Preferred Stock, the Voting
Preferred Stock, the Director Preferred Stock, any shares of Junior
Participating Preferred Stock issued pursuant to the Rights and any other class
or series of capital stock of the Company now or hereafter issued and
outstanding that ranks junior as to the payment of dividends and amounts
payable upon liquidation, dissolution or winding up to the Redeemable Preferred
Stock.
 
 Voting Rights
 
  Except as otherwise from time to time required by applicable law, the holders
of shares of Redeemable Preferred Stock will not have any voting rights and
their consent will not be required for taking any corporate action. When and if
the holders of the Redeemable Preferred Stock are entitled to vote, each share
will be entitled to one vote.
 
THE ESOP PREFERRED STOCK
   
  The summary of terms of the ESOP Preferred Stock contained in this Proxy
Statement/Prospectus does not purport to be complete and is subject to, and is
qualified in its entirety by, the provisions of the Restated Certificate that
will become effective in connection with the consummation of the
Recapitalization. A copy of the Restated Certificate is included elsewhere in
this Proxy Statement/Prospectus.     
 
 General
 
  The ESOP Preferred Stock will consist of two similar classes of Preferred
Stock of the Company that will be designated as Class 1 ESOP Convertible
Preferred Stock (the "Class 1 ESOP Preferred Stock") and Class 2 ESOP
Convertible Preferred Stock (the "Class 2 ESOP Preferred Stock" and, together
with the Class 1 ESOP Preferred Stock, the "ESOP Preferred Stock"). Where the
summaries do not make a distinction between the Class 1 ESOP Preferred Stock
and the Class 2 ESOP Preferred Stock, such summaries refer to either class.
   
  An aggregate of up to 17,675,345 shares of Class 1 ESOP Preferred Stock and
Class 2 ESOP Preferred Stock will be issued to the ESOP Trustee in connection
with the Recapitalization. See "THE PLAN OF RECAPITALIZATION--Establishment of
ESOPs." The shares of the ESOP Preferred Stock will be convertible into New
Shares as described below. If all the shares of ESOP Preferred Stock to be
issued in connection with the Recapitalization were to be converted into New
Shares immediately upon issuance, such New Shares would constitute
approximately 55% of the New Shares (including New Shares issuable upon
exercise of the ESOP Preferred Stock) that would be outstanding at that time,
on a fully diluted basis based on the treasury stock method. If the New Shares
maintain an average fair market value that exceeds $136 per share during the
year following the Issue Date that is established under the Plan of
Recapitalization, a number of additional shares of ESOP Preferred Stock will be
issued or reserved for issuance as Book-Entry Shares. With the issuance or
reservation for issuance of such additional shares, the ownership interest     
 
                                      165
<PAGE>
 
   
of the ESOPs could be increased from approximately 55% to up to approximately
63% of the Company. See "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--
Additional Shares."     
 
 Ranking
   
  The ESOP Preferred Stock will rank junior to the Series A Preferred Stock,
the Public Preferred and the Redeemable Preferred Stock and will rank senior to
the New Shares, the Voting Preferred Stock, the Director Preferred Stock and
any shares of Junior Participating Preferred Stock issued pursuant to the
Rights with respect to payment of dividends and amounts payable upon
liquidation, dissolution or winding up. The Class 1 ESOP Preferred Stock will
rank senior to the Class 2 ESOP Preferred Stock with respect to the payment of
Fixed Dividends (as defined below) and the Class 1 ESOP Preferred Stock will
rank on a parity with the Class 2 ESOP Preferred Stock as to the payment of
Participating Dividends (as defined below) and as to amounts payable upon
liquidation, dissolution or winding up.     
 
 Dividends
   
  Holders of Class 1 ESOP Preferred Stock will be entitled to receive, when, as
and if declared by the Board of Directors of the Company out of assets of the
Company legally available therefor, cumulative cash dividends at a rate per
annum of a dollar amount per share of Class 1 ESOP Preferred Stock not to
exceed, without the consent of the unions, seven percent of the price per share
paid by the ESOP Trustee for such shares at the Effective Time (See "THE PLAN
OF RECAPITALIZATION--Establishment of ESOPs--Sales of ESOP Preferred Stock")
(the "Fixed Dividend"). The Fixed Dividends on the Class 1 ESOP Preferred Stock
will cease to accrue on March 31, 2000. Under certain circumstances, any Fixed
Dividends that remain accrued and unpaid on April 1, 2000 will not prevent the
payment of dividends on any capital stock of the Company that ranks junior to
the Class 1 ESOP Preferred Stock with respect to the payment of dividends,
although such accrued and unpaid Fixed Dividends will remain a part of the
Liquidation Preference (as defined below) payable in respect of the Class 1
ESOP Preferred Stock upon any liquidation, dissolution or winding up of the
Company. In addition, if during any 12-month period ending on the annual
dividend payment date, holders of the New Shares receive any cash dividends or
cash distributions thereon, and the aggregate amount of such dividends and
distributions that would have been received, during such period, by the holder
of a share of Class 1 ESOP Preferred Stock had such share of Class 1 ESOP
Preferred Stock been converted into New Shares exceeds, the amount of the Fixed
Dividend paid on such share of Class 1 ESOP Preferred Stock, then the holders
of the Class 1 ESOP Preferred Stock will be entitled to receive an additional
cash dividend in an amount equal to such excess (the "Participating Dividend"),
although the aggregate amount of the Fixed Dividend and the Participating
Dividend paid on any share of Class 1 ESOP Preferred Stock with respect to any
annual dividend period may not exceed 12 1/2% of the fair market value of the
New Shares into which such share of Class 1 ESOP Preferred Stock is
convertible.     
 
  Holders of Class 2 ESOP Preferred Stock will not be entitled to receive any
Fixed Dividend. If during any 12-month period ending on the annual dividend
payment date, holders of the New Shares receive any cash dividends or cash
distributions thereon, then the holders of the Class 2 ESOP Preferred Stock
will be entitled to receive a cash dividend in an amount equal to the dividend
they would have received had their shares of Class 2 ESOP Preferred Stock been
converted into and were outstanding as New Shares at all relevant times,
although the aggregate amount of the dividend paid on any share of Class 2 ESOP
Preferred Stock with respect to any annual dividend period may not exceed 12
1/2% of the fair market value of the New Shares into which it is convertible.
 
  If the holders of the New Shares receive cash dividends and cash
distributions that exceed 12 1/2% of the fair market value of such shares, such
excess will be applied to adjust the Conversion Rate (as defined below) on the
ESOP Preferred Stock.
 
  Except as described above, the Company will not (i) declare, pay or set apart
funds for the payment of any dividend or other distribution with respect to any
Junior Stock (as defined below) or (ii) redeem, purchase or otherwise acquire
for consideration any Junior Stock or Parity Stock (as defined below) through a
sinking fund or otherwise (except by conversion into or exchange for shares of
Junior Stock and other than a
 
                                      166
<PAGE>
 
   
redemption or purchase or other acquisition of New Shares made for purposes of
an employee incentive or benefit plan of the Company or any subsidiary), unless
all accrued and unpaid dividends with respect to the ESOP Preferred Stock and
any Parity Stock at the time such dividends are payable have been paid or funds
have been set apart for payment of such dividends.     
   
  For purposes of the description of the ESOP Preferred Stock, (i) the term
"dividend" does not include dividends payable solely in shares of Junior Stock
on Junior Stock, or in options, warrants or rights to holders of Junior Stock
to subscribe for or purchase any Junior Stock, (ii) the term "Parity Stock"
means any class or series of preferred stock ranking on a parity with the ESOP
Preferred Stock as to payment of dividends (with respect to such dividends) or
amounts payable upon liquidation, dissolution or winding up (with respect to
such amounts) and (iii) the term "Junior Stock" means the New Shares, the
Voting Preferred Stock, the Director Preferred Stock, any shares of Junior
Participating Preferred Stock issued pursuant to the Rights and any other class
or series of capital stock of the Company now or hereafter issued and
outstanding that ranks junior as to the payment of dividends (with respect to
such dividends) or amounts payable upon liquidation, dissolution or winding up
(with respect to such amounts) to the ESOP Preferred Stock.     
 
 Conversion
   
  The ESOP Preferred Stock will be convertible, in whole or in part, at any
time and from time to time, into New Shares initially at the rate (for purposes
of the description of ESOP Preferred Stock, the "Conversion Rate") of one New
Share for each share of ESOP Preferred Stock converted. The Conversion Rate
will be adjusted if there occurs an Equity Adjustment unless the Additional
Shares are transferred to the ESOP, as described under "THE PLAN OF
RECAPITALIZATION--Establishment of ESOPs--Additional Shares." In addition, the
Conversion Rate on the ESOP Preferred Stock will be adjusted upon the
occurrence of a variety of events, including, without limitation, a
distribution of capital stock to holders of New Shares, a subdivision,
recombination or reclassification of the New Shares, the issuance to holders of
New Shares of rights to subscribe for equity securities at a price per New
Share that is less than the fair market value of a New Share, the issuance of
New Shares or securities representing a right to acquire New Shares at a price
per New Share that is less than the fair market value of a New Share, the
payment of cash dividends and cash distributions to holders of New Shares that
exceed in the aggregate 12 1/2% of the fair market value of the New Shares, the
payment of any non-cash dividend or distribution to holders of New Shares and
certain Pro Rata Repurchases of New Shares.     
 
 Redemption
 
  The ESOP Preferred Stock will not be redeemable.
 
 Liquidation Preference
   
  The holders of shares of ESOP Preferred Stock will be entitled to receive, in
the event of any liquidation, dissolution or winding up of the Company, a
dollar amount per share equal to the price per share paid by the ESOP Trustee
for such shares at the Effective Time (see "THE PLAN OF RECAPITALIZATION--
Establishment of ESOPs--Sales of ESOP Preferred Stock"), plus an amount per
share equal to all dividends (whether or not earned or declared) accrued and
unpaid thereon to the date of final distribution to such holders, including,
without limitation, Fixed Dividends in respect of the Class 1 ESOP Preferred
Stock that are accrued and unpaid as of April 1, 2000 (but that will not
prevent the payment of dividends on any capital stock of the Company that ranks
junior to the Class 1 ESOP Preferred Stock with respect to the payment of
dividends) (for purposes of the description of the ESOP Preferred Stock, the
"Liquidation Preference"), and no more.     
 
  Until the holders of the ESOP Preferred Stock have been paid the Liquidation
Preference in full, no payment will be made to any holder of Junior Stock upon
the liquidation, dissolution or winding up of the Company. If, upon any
liquidation, dissolution or winding up of the Company, the assets of the
Company, or proceeds thereof, distributable among the holders of the shares of
ESOP Preferred Stock are insufficient to pay in full the Liquidation Preference
and the liquidation preference with respect to any other shares of Parity
 
                                      167
<PAGE>
 
   
Stock, then such assets, or the proceeds thereof, will be distributed among the
holders of shares of ESOP Preferred Stock and any such Parity Stock ratably in
accordance with the respective amounts that would be payable on such shares of
ESOP Preferred Stock and any such Parity Stock if all amounts payable thereon
were paid in full. Neither a consolidation or merger of the Company with
another corporation nor a sale, lease or transfer of all or substantially all
of the Company's assets will be considered a liquidation, dissolution or
winding up, voluntary or involuntary, of the Company.     
 
 Voting Rights
 
  Except as otherwise from time to time required by applicable law, the holders
of shares of ESOP Preferred Stock will not have any voting rights, and their
consent will not be required for taking any corporate action. When and if the
holders of ESOP Preferred Stock are entitled to vote, each share will be
entitled to one vote.
 
 Consolidation, Merger, etc.
 
  Upon the occurrence of certain mergers and other similar transactions, the
holders of the ESOP Preferred Stock will be entitled to receive depending on
the circumstances either (i) a preferred stock having the same powers,
preference and relative, participating, optional or other special rights as the
class of ESOP Preferred Stock they held prior to such merger or other
transaction or (ii) the consideration receivable by the holders of the number
of New Shares into which such shares of ESOP Preferred Stock could have been
converted immediately prior to such merger or other transaction.
 
THE VOTING PREFERRED STOCK
   
  The summary of terms of the Voting Preferred Stock contained in this Proxy
Statement/Prospectus does not purport to be complete and is subject to, and is
qualified in its entirety by, the provisions of the Restated Certificate that
will become effective in connection with the consummation of the
Recapitalization. A copy of the Restated Certificate is included elsewhere in
this Proxy Statement/Prospectus.     
 
 General
   
  The Voting Preferred Stock will consist of three similar classes of Preferred
Stock of the Company that will be designated as Class P ESOP Voting Junior
Preferred Stock, which will be allocated to ESOP accounts of employees
represented by ALPA (the "Class P Voting Preferred Stock"), Class M ESOP Voting
Junior Preferred Stock, which will be allocated to ESOP accounts of employees
represented by the IAM (the "Class M Voting Preferred Stock") and Class S ESOP
Voting Junior Preferred Stock, which will be allocated to Salaried and
Management Employees' accounts (the "Class S Voting Preferred Stock" and,
together with the Class P Voting Preferred Stock and the Class M Voting
Preferred Stock, the "Voting Preferred Stock"). Where the summaries do not make
a distinction between the Class M Voting Preferred Stock, the Class P Voting
Preferred Stock and the Class S Voting Preferred Stock, such summaries refer to
any such class.     
   
  One share of Class P Voting Preferred Stock, one share of Class M Voting
Preferred Stock and one share of Class S Voting Preferred Stock will be issued
to the ESOP Trustee in connection with the Recapitalization at the Effective
Time. See "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs."     
 
 Voting Rights
   
  The Voting Preferred Stock will vote with the holders of the New Shares as a
single class on all matters (except as to such matters as to which a separate
class vote may be required by the DGCL), except that until the Sunset, holders
of the Voting Preferred Stock will not be entitled to vote to elect members of
the Board of Directors. Until the Sunset, the Voting Preferred Stock will
represent the right to cast in the aggregate approximately 55% of the votes of
all classes of capital stock that will vote together with the New Shares as
    
                                      168
<PAGE>
 
   
a single class (other than for the election of members to the Board of
Directors), subject to reduction for the number of New Shares that have been
issued upon conversion of shares of the ESOP Preferred Stock that continue to
be held by the ESOP. If the fair market value of the New Shares exceeds $136
per share during the year following the Effective Time, the number of votes
represented by the Voting Preferred Stock will be increased above approximately
55% of the New Shares (including New Shares issuable upon exercise of the ESOP
Preferred Stock that would be outstanding reserved for issuance as Book-Entry
Shares or remaining to be transferred to the ESOPs) to up to a maximum of
approximately 63%. See "THE PLAN OF RECAPITALIZATION--Establishment of ESOPs--
Additional Shares."     
   
  The voting power of the Voting Preferred Stock will be held in the Agreed
Percentages. Accordingly, by way of example, assuming that the Voting Preferred
Stock in the aggregate has the right to cast approximately 55% of the voting
power of the Company on a fully diluted basis based on the treasury stock
method, the Class P Voting Preferred Stock will be entitled to cast
approximately 24.5%, the Class M Voting Preferred Stock will be entitled to
cast approximately 19.7%, and the Class S Voting Preferred Stock will be
entitled to cast approximately 8.8%, subject to reduction as noted above.     
   
  After the Sunset, each class of Voting Preferred Stock will represent the
right to cast in the aggregate the number of votes that is equal to the
relevant Agreed Percentage of the number of New Shares into which the ESOP
Preferred Stock can be converted plus the number of Book-Entry Shares remaining
to be issued plus the number of Shares of ESOP Preferred Stock, if any,
remaining to be transferred to the ESOP. See "THE PLAN OF RECAPITALIZATION--
Establishment of ESOPs--General."     
 
 Other
 
  The Voting Preferred Stock will not be entitled to receive any dividends. The
Voting Preferred Stock will be convertible into New Shares at the rate of one
ten-thousandth of a New Share for each share of Voting Preferred Stock
converted. All the Voting Preferred Stock will be converted into New Shares
automatically upon the occurrence of an Uninstructed Trustee Action (as defined
below) or at such time when none of the ESOP Preferred Stock remains
outstanding. The Voting Preferred Stock will have a liquidation preference of
$0.01 per share.
 
  Upon the occurrence of certain mergers and other similar transactions, the
holders of the Voting Preferred Stock will be entitled to receive a preferred
stock having the same powers, preference and relative, participating, optional
or other special rights as the class of Voting Preferred Stock they held prior
to such merger or other transaction except that such preferred stock will not
control 53% of the vote.
 
THE DIRECTOR PREFERRED STOCK
   
  The summary of terms of the Director Preferred Stock contained in the Proxy
Statement/Prospectus does not purport to be complete and is subject to, and is
qualified in its entirety by, the provisions of the Restated Certificate that
will become effective in connection with the consummation of the
Recapitalization. A copy of the Restated Certificate is included elsewhere in
this Proxy Statement/Prospectus.     
 
 General
 
  The Director Preferred Stock will consist of four classes of Preferred Stock
of the Company that will be designated as the Class I Junior Preferred Stock
(the "Class I Preferred Stock"), the Class Pilot MEC Junior Preferred Stock
(the "Class Pilot MEC Preferred Stock"), the Class IAM Junior Preferred Stock
(the "Class IAM Preferred Stock") and the Class SAM Junior Preferred Stock (the
"Class SAM Preferred Stock" and, together with the Class I Preferred Stock, the
Class Pilot MEC Preferred Stock and the Class IAM Preferred Stock, the
"Director Preferred Stock"). Where the summaries do not make a distinction
among the several classes of Director Preferred Stock, such summaries refer to
any of them.
   
  Each of the classes of Director Preferred Stock has the power to elect one or
more members of the Board. None of the classes of Director Preferred Stock will
bear dividends. Each class of Director Preferred Stock will have a liquidation
preference of $0.01 per share.     
 
                                      169
<PAGE>
 
   
  Each of the Class Pilot MEC Preferred Stock, the Class IAM Preferred Stock
and the Class SAM Preferred Stock provides that upon the consolidation, merger
or similar transaction involving the Company or United, pursuant to which the
outstanding New Shares are to be exchanged for or converted into securities of
a successor or resulting company or cash or other property, the Class Pilot MEC
Preferred Stock, the Class IAM Preferred Stock and the Class SAM Preferred
Stock, respectively, will be converted into, or exchanged for, preferred stock
of such successor or resulting company having, in respect of such company, the
same powers, preferences and relative, participating, optional or other special
rights, and the qualifications, limitations or restrictions thereof, that the
original Class Pilot MEC Preferred Stock, Class IAM Preferred Stock and Class
SAM Preferred Stock had, respectively.     
 
 Class I Preferred Stock
 
  The Class I Preferred Stock will be issued initially to Duane D. Fitzgerald,
Richard D. McCormick, John K. Van de Kamp and Paul A. Volcker who will serve as
the Independent Directors of the Company immediately following consummation of
the Recapitalization. The Restated Certificate authorizes the issuance of 10
shares of Class I Preferred Stock, although the Company expects that no more
than four shares will be outstanding at any time. The shares of Class I
Preferred Stock will be issued to the initial holders thereof pursuant to a
subscription agreement for a purchase price that is equal to the $0.01
liquidation value thereof.
   
  The initial holders of the Class I Preferred Stock will enter into a
Stockholders' Agreement among themselves, ALPA, the IAM and the Company (the
"Class I Preferred Stockholders' Agreement"), pursuant to which the holders
agree to vote their shares to elect the Independent Directors nominated
pursuant to the provisions described in "THE PLAN OF RECAPITALIZATION--Revised
Governance Structure-- Independent Directors," and to refrain from transferring
the shares of Class I Preferred Stock other than to a person who has been
elected to serve as one of the Independent Directors and who agrees to be
subject to the provisions of the Class I Preferred Stockholders' Agreement.
Both the Restated Certificate and the Class I Preferred Stockholders' Agreement
provide that the Company, subject to legally available funds will redeem or
purchase the shares of Class I Preferred Stock held by any holder thereof who
votes contrary to the Class I Preferred Stockholder's Agreement or who purports
to transfer the share of Class I Preferred Stock to any person other than an
Independent Director. Any share of Class I Preferred Stock redeemed or purchase
as provided in the immediately prior sentence may be reissued as provided in
the Restated Certificate or the Class I Preferred Stockholders' Agreement. All
shares of the Class I Preferred Stock will be redeemed automatically upon the
occurrence of the Sunset, and following such redemption, none of the shares of
Class I Preferred Stock may be reissued thereafter.     
 
 Class Pilot MEC Preferred Stock and Class IAM Preferred Stock
   
  The Restated Certificate authorizes the issuance of one share of each of the
Class Pilot MEC Preferred Stock and the Class IAM Preferred Stock. The share of
the Class Pilot MEC Preferred Stock will be issued to the ALPA MEC, and the
share of Class IAM Preferred Stock will be issued to the IAM or its designee,
each pursuant to a subscription agreement for a purchase price equal to the
$0.01 liquidation value thereof. Each of the Class Pilot MEC Preferred Stock
and the Class IAM Preferred Stock will have the right to elect one Employee
Director, and the shares of such stock will be redeemed automatically upon the
purported transfer thereof to any person other than the holder thereof
authorized under the Restated Certificate. The Class Pilot MEC Preferred Stock
will be redeemed automatically upon the later of the Sunset or the occurrence
of the ALPA Termination Date. The Class IAM Preferred Stock will be redeemed
automatically upon the later of the Sunset or the occurrence of the IAM
Termination Date.     
 
 Class SAM Preferred Stock
 
  The Class SAM Preferred Stock will be issued initially to the person
nominated to serve as the Salaried and Management Director of the Company
immediately following consummation of the Recapitalization and to an additional
holder (the "Designated Holder"). The Restated Certificate authorizes the
issuance of ten
 
                                      170
<PAGE>
 
shares of Class SAM Preferred Stock, although the Company expects that no more
than three shares will be outstanding at any time. Two shares of Class SAM
Preferred Stock will be held by the Salaried and Management Director, and one
share will be issued to the Designated Holder, pursuant to a subscription
agreement for a purchase price that is equal to the $0.01 liquidation value
thereof.
   
  The initial holders of the Class SAM Preferred Stock will enter into a
Stockholders' Agreement among themselves and the Company (the "Class SAM
Preferred Stockholders' Agreement"), pursuant to which the holders agree to
vote their shares to elect the Salaried and Management Director nominated by
the System Roundtable, and to refrain from transferring the shares of Class SAM
Preferred Stock other than to a person who has been elected to serve as the
Salaried and Management Director or another person designated by the System
Roundtable to be the Designated Holder, each of whom must agree to be subject
to the provisions of the Class SAM Preferred Stockholders' Agreement. The Class
SAM Preferred Stockholders' Agreement provides that in most instances the
Designated Holder will be the senior executive of United who has primary
responsibility for human resources. Both the Restated Certificate and the Class
SAM Preferred Stockholders' Agreement provide that the Company, subject to
legally available funds, will redeem or purchase the shares of Class SAM
Preferred Stock of any holder who votes contrary to the instructions given by
the System Roundtable or who purports to transfer the share or shares of Class
SAM Preferred Stock to any person other than the Salaried and Management
Director or another person designated by the System Roundtable. The Restated
Certificate provides that no holder of shares of Class SAM Preferred Stock will
have the right to vote unless at such time such person is the Salaried and
Management Director of the Designated Holder. Any share of Class SAM Preferred
Stock that is redeemed or purchase as provided in the immediately prior
sentence may be reissued as provided in the Restated Certificate and the Class
SAM Preferred Stockholders' Agreement. All shares of the Class SAM Preferred
Stock will be redeemed automatically on or after the Sunset upon the earlier to
occur of the ALPA Termination Date and the IAM Termination Date, and following
such redemption, none of the shares of Class SAM Preferred Stock may be
reissued thereafter.     
 
 Uninstructed Trustee Actions
   
  Under certain circumstances prior to the Sunset, described below, (i) the
Voting Preferred Stock will cease to vote and (ii) the right to cast the votes
that the holder of the Voting Preferred Stock would otherwise have been
entitled to cast will be transferred generally in the following percentages:
46.23% to the holder of the Class Pilot MEC Preferred Stock, 37.13% to the
holder of the Class IAM Preferred Stock and 16.64% to the holders of the Class
SAM Preferred Stock.     
   
  In connection with (i) a stockholder vote on a transaction involving a merger
of the Company or United or a change of control of the Company or United, or
(ii) if the trustee under either ESOP enters into a binding commitment with
respect to any such transaction or (iii) if the trustee disposes of 10% or more
of the common equity initially represented by the ESOP Preferred Stocks, (x) if
the trustee either (1) fails to solicit timely instructions from the Plan
participants or the Committees or (2) fails to act in accordance with the
instructions received, (y) if the merger or change of control transaction would
have been approved or if the trustee disposes of 10% or more of the common
equity initially represented by the ESOP Preferred Stocks and (z) (I) the
trustee solicited instructions, failed to follow them and such transaction
would not have been approved if the trustee had followed the instructions, (II)
the trustee failed to follow instructions and the transaction would not have
been approved had the trustee cast all the votes represented by securities in
the Plan against the transaction or (III) the trustee failed to follow
instructions or to solicit instructions with respect to a matter upon which no
vote is required (the occurrence of the conditions set forth in clauses (x),
(y) and (z) being referred to as an "Uninstructed Trustee Action"), the voting
rights of the Voting Preferred Stocks will be transferred from the Voting
Preferred Stock to the Class Pilot MEC Preferred Stock, the Class IAM Preferred
Stock and the Class SAM Preferred Stock in the proportions referred to above.
In addition, if the trustee fails to solicit instructions or disregards
instructions received in respect of a vote on a transaction which, if
consummated, would constitute an Uninstructed Trustee Action, then the voting
power of the Voting Preferred Stock will shift to the Class Pilot MEC Preferred
Stock, the Class IAM Preferred Stock and the Class SAM Preferred Stock and the
transaction must be approved by the vote of the Class Pilot MEC Preferred
Stock, the Class IAM Preferred stock and the Class SAM Preferred Stock voting
together as     
 
                                      171
<PAGE>
 
a class with the New Shares, in addition to any other vote required by the
Restated Certificate, stock exchange requirements or applicable law.
   
  In addition, if the Sunset occurs directly or indirectly as a result of an
Uninstructed Trustee Action (or for any reason within one year after an
Uninstructed Trustee Action), the voting power to which the Class Pilot MEC
Preferred Stock, the Class IAM Preferred stock and the Class SAM Preferred
Stock succeed as a result of an Uninstructed Trustee Action will survive until
the anniversary of the Issue Date that occurs in the year 2010.     
 
THE COMMON STOCK, THE SERIES A PREFERRED STOCK AND THE JUNIOR PARTICIPATING
PREFERRED STOCK
   
  The following descriptions do not purport to be complete and are subject to,
and qualified in their entirety by reference to, the more complete descriptions
thereof set forth in the following documents, all of which have been filed as
exhibits to the Registration Statement of which this Proxy Statement/Prospectus
is a part: (i) the Company's current Amended and Restated Certificate of
Incorporation, (ii) its current By-Laws, (iii) the Restated Certificate that
will become effective upon the consummation of the Recapitalization, (iv) the
By-Laws that will become effective upon the consummation of the
Recapitalization and (v) the Rights Agreement, as amended, between the Company
and First Chicago Trust Company of New York, as Rights Agent, pursuant to which
shares of Series C Junior Participating Preferred Stock ("Junior Participating
Preferred Stock") are issuable. A copy of the Restated Certificate is included
elsewhere in this Proxy Statement/Prospectus. Where the descriptions do not
make a distinction between the Old Shares and the New Shares, such descriptions
are applicable to both.     
 
 Common Stock
   
  Dividend Rights. Holders of Old Shares are entitled to, and holders of New
Shares will be entitled to, receive dividends when, as and if declared by the
Board out of funds legally available therefor, provided that, so long as any
shares of preferred stock are outstanding, no dividends (other than dividends
payable in common stock) or other distributions may be made with respect to the
Old Shares (or, after the Effective Time, New Shares) unless full cumulative
dividends on the shares of preferred stock have been paid. The Company has not
paid cash dividends on the Old Shares since the third quarter of 1987.     
 
  As a holding company, the Company relies on distributions from United to pay
dividends on its capital stock. There are currently no contractual restrictions
on United's ability to pay dividends to the Company.
 
  Voting Rights. Holders of Old Shares are entitled to one vote per share in
the election of directors and on any question arising at any stockholders'
meeting, voting as a single class. The New Shares will be entitled to cast one
vote per share. Upon the consummation of the Recapitalization and prior to the
Sunset, the New Shares and the Voting Preferred Stock will vote together as a
single class with respect to all matters submitted to the vote of the holders
of common stock pursuant to law or as provided in the Restated Certificate
except with respect to (a) such matters upon which the DGCL requires a separate
class vote and (b) the election of the Public Directors, whom the New Shares
will elect separately as a class. Until the Sunset, the New Shares will not
vote to elect any directors other than the Public Directors. After the Sunset,
the New Shares and the Voting Preferred Stock will continue to vote together as
a single class with respect to all matters submitted to the vote of the holders
of common stock pursuant to law or as provided in the Restated Certificate
except with respect to such matters upon which the DGCL requires a separate
class vote. See "--The Voting Preferred Stock--Voting Rights."
   
  Right of First Refusal. In connection with the Recapitalization, the Company
will enter into a First Refusal Agreement (the "First Refusal Agreement") with
ALPA, the IAM and the Salaried and Management Director (solely as the
representative of the Salaried and Management Employees) pursuant to which the
Company will agree that, if it proposes to issue any New Shares or other
securities that are exchangeable for or convertible into New Shares
(collectively, the "Equity Securities"), it must first offer such Equity
Securities     
 
                                      172
<PAGE>
 
   
to ALPA and the IAM on behalf of the employees represented thereby and to the
Salaried and Management Employees on the same terms and conditions upon which
the Company proposes to sell such Equity Securities to a third party. Under the
First Refusal Agreement, the members of ALPA will be entitled to purchase
46.23% of the Equity Securities offered, the members of the IAM will be
entitled to purchase 37.13% of the Equity Securities offered and the Salaried
and Management Employees will be entitled to purchase 16.64% of the Equity
Securities offered. The First Refusal Agreement will terminate on the Sunset.
    
 Series A Preferred Stock
   
  Dividends. Holders of shares of Series A Preferred Stock are entitled to
receive, when, as and if declared by the Board of the Company out of assets of
the Company legally available therefor, cumulative cash dividends at the rate
per annum of $6.25 per share of Series A Preferred Stock. Dividends on the
Series A Preferred Stock are payable quarterly in arrears. Dividends on the
Series A Preferred Stock are cumulative, and accumulations of dividends on
shares of Series A Preferred Stock do not bear interest.     
 
  Except as provided in the next sentence, no dividend will be declared or paid
on any Parity Stock (as defined below) unless full cumulative dividends have
been paid on the Series A Preferred Stock for all prior dividend periods. If
accrued dividends on the Series A Preferred Stock for all prior dividend
periods have not been paid in full then any dividend declared on the Series A
Preferred Stock for any dividend period and any dividend on any Parity Stock
will be declared ratably in proportion to accrued and unpaid dividends on the
Series A Preferred Stock and such Parity Stock.
   
  The Company will not (i) declare, pay or set apart funds for the payment of
any dividend or other distribution with respect to any Junior Stock (as defined
below) or (ii) redeem, purchase or otherwise acquire for consideration any
Junior Stock or Parity Stock through a sinking fund or otherwise (except by
conversion into or exchange for shares of Junior Stock and other than a
redemption or purchase or other acquisition of shares of common stock of the
Company made for purposes of an employee incentive or benefit plan of the
Company or any subsidiary), unless all accrued and unpaid dividends with
respect to the Series A Preferred Stock and any Parity Stock at the time such
dividends are payable have been paid or funds have been set apart for payment
of such dividends.     
 
  For purposes of the description of the Series A Preferred Stock, (i) the term
"dividend" does not include dividends payable solely in shares of Junior Stock
on Junior Stock, or in options, warrants or rights to holders of Junior Stock
to subscribe for or purchase any Junior Stock, (ii) the term "Parity Stock"
means any class or series of preferred stock ranking on a parity with the
Series A Preferred Stock as to payment of dividends and amounts payable upon
liquidation, dissolution or winding up and (iii) the term "Junior Stock" means
the common stock (Old Shares or New Shares), the ESOP Preferred Stock, the
Voting Preferred Stock, the Director Preferred Stock, any shares of Junior
Participating Preferred Stock issued pursuant to the Rights, and any other
class or series of capital stock of the Company now or hereafter issued and
outstanding that ranks junior as to the payment of dividends or amounts payable
upon liquidation, dissolution or winding up to the Series A Preferred Stock.
 
  Redemption. The Series A Preferred Stock is not redeemable prior to May 1,
1996. On and after such date, the Series A Preferred Stock is redeemable at the
option of the Company, in whole or in part, initially at $104.375 per share and
thereafter at prices declining ratably on each May 1 to $100.00 per share on
and after May 1, 2003, plus, in each case, all accrued and unpaid dividends.
Unless converted by the holders or redeemed by the Company, the Series A
Preferred Stock will have perpetual maturity.
 
  Liquidation Preference. The holders of shares of Series A Preferred Stock
will be entitled to receive, in the event of any liquidation, dissolution or
winding up of the Company, $100 per share plus an amount per share equal to all
dividends (whether or not earned or declared) accrued and unpaid thereon to the
date of final distribution to such holders (for purposes of the description of
the Series A Preferred Stock, the "Liquidation Preference"), and no more.
 
                                      173
<PAGE>
 
  Until the holders of the Series A Preferred Stock have been paid the
Liquidation Preference in full, no payment will be made to any holder of Junior
Stock upon the liquidation, dissolution or winding up of the Company. If, upon
any liquidation, dissolution or winding up of the Company, the assets of the
Company, or proceeds thereof, distributable among the holders of the shares of
Series A Preferred Stock are insufficient to pay in full the Liquidation
Preference and the liquidation preference with respect to any other shares of
Parity Stock, then such assets, or the proceeds thereof, will be distributed
among the holders of shares of Series A Preferred Stock and any such Parity
Stock ratably in accordance with the respective amounts which would be payable
on such shares of Series A Preferred Stock and any such Parity Stock if all
amounts payable thereon were paid in full. Neither a consolidation or merger of
the Company with another corporation nor a sale or transfer of all or
substantially all of the Company's assets will be considered a liquidation,
dissolution or winding up, voluntary or involuntary, of the Company.
 
  Voting Rights. Except as indicated below, or except as otherwise from time to
time required by applicable law, the holders of shares of Series A Preferred
Stock will not have any voting rights, and their consent will not be required
for taking any corporate action. When and if the holders of the Series A
Preferred Stock are entitled to vote, each share will be entitled to one vote.
 
  If the equivalent of six quarterly dividends payable on the Series A
Preferred Stock or any other series of Serial Preferred Stock of the Company
have not been declared and paid or set apart for payment, whether or not
consecutive, the number of directors of the Company will be increased by two
and the holders of all such series in respect of which such a default exists,
voting as a class without regard to series, will be entitled to elect two
additional directors at the next annual meeting and each subsequent meeting,
until all cumulative dividends have been paid in full.
   
  The affirmative vote or consent of the holders of 66 2/3% of the outstanding
shares of the Series A Preferred Stock, voting separately as a class with all
other affected series of Serial Preferred Stock that is also a Parity Stock,
will be required for any amendment of the Restated Certificate which alters or
changes the powers, preferences, privileges or rights of the Series A Preferred
Stock so as to materially adversely affect the holders thereof. The affirmative
vote or consent of the holders of shares representing 66 2/3% of the
outstanding shares of the Series A Preferred Stock and any other series of
Parity Stock, voting as a single class without regard to series, will be
required to authorize the creation or issue of, or reclassify any authorized
stock of the Company into, or issue or authorize any obligation or security
convertible into or evidencing a right to purchase, any additional class or
series of stock ranking senior to all such series of Parity Stock.     
 
  Except as required by law, the holders of Series A Preferred Stock will not
be entitled to vote on any merger or consolidation involving the Company or a
sale of all or substantially all of the assets of the Company.
   
  Conversion Rights. Shares of Series A Preferred Stock are convertible, in
whole or in part, at any time at the option of the holders thereof, into Old
Shares. As of the date of this Proxy Statement/Prospectus, the conversion price
is $156.50 per Old Share (equivalent to a rate of approximately 0.639 Old
Shares for each share of Series A Preferred Stock), subject to adjustment as
set forth in the Restated Certificate ("Conversion Price"). Upon consummation
of the Recapitalization, each share of Series A Preferred Stock will receive,
upon conversion thereof, in respect of each Old Share into which such share of
Series A Preferred Stock was convertible immediately prior to the Effective
Time of the Recapitalization. The right to convert shares of Series A Preferred
Stock called for redemption will terminate at the close of business on the day
preceding a redemption date.     
 
 Junior Participating Preferred Stock
 
  General. The Company has designated 1,250,000 shares of a series of Serial
Preferred Stock as Junior Participating Preferred Stock and such shares are
reserved for issuance upon exercise of the Rights associated
 
                                      174
<PAGE>
 
   
with each share of Common Stock. See "--Preferred Share Purchase Rights" below.
As of the date of this Proxy Statement/Prospectus, there are no shares of
Junior Participating Preferred Stock outstanding.     
 
  Ranking. The Junior Participating Preferred Stock ranks junior to all other
series of preferred stock as to dividends and amounts payable upon any
voluntary or involuntary liquidation, dissolution or winding up of the Company
unless the terms of any such other series shall provide otherwise.
   
  Dividends. Holders of shares of Junior Participating Preferred Stock will be
entitled to receive, when, as and if declared by the Board of Directors of the
Company out of funds legally available therefor, cumulative cash dividends
payable quarterly on the fifteenth day of January, April, July and October in
each year (each such date being a "Quarterly Dividend Payment Date"),
commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Junior Participating Preferred
Stock, in an amount per share equal to the greater of (a) $10.00 or (b) subject
to certain provisions for adjustment set forth in the Restated Certificate, 100
times the aggregate per share amount of all cash dividends, and 100 times the
aggregate per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of common stock or a
subdivision of the outstanding shares of common stock since the immediately
preceding Quarterly Dividend Payment Date or, with respect to the first
Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Junior Participating Preferred Stock.     
 
  The Company must declare a dividend or distribution on the Junior
Participating Preferred Stock immediately after it declares a dividend or
distribution on common stock (other than a dividend payable in shares of common
stock), provided that in the event no dividend or distribution has been
declared on common stock during the period between any Quarterly Dividend
Payment Date and the next subsequent Quarterly Dividend Payment Date, a
dividend of $10.00 per share on the Junior Participating Preferred Stock will
nevertheless be payable on such subsequent Quarterly Dividend Payment Date.
 
  The Restated Certificate sets forth certain restrictions imposed upon the
Company whenever quarterly dividends or other distributions payable on Junior
Participating Preferred Stock are in arrears, including, but not limited to,
restrictions on the Company's ability to declare or pay dividends on, make any
other distributions on, redeem or purchase or otherwise acquire for
consideration shares ranking junior to or on a parity with the Junior
Participating Preferred Stock either as to dividends or amounts payable upon
liquidation, dissolution or winding up of the Company.
 
  Redemption. When issued and outstanding, the shares of Junior Participating
Preferred Stock will not be redeemable.
 
  Liquidation Preference. Subject to (a) the rights of holders of preferred
stock of the Company ranking senior to Junior Participating Preferred Stock as
to dividends and amounts payable upon any voluntary or involuntary liquidation,
dissolution or winding up and (b) any other provision of the Restated
Certificate, upon any voluntary or involuntary liquidation, dissolution or
winding up of the Company, no distribution shall be made (1) to the holders of
shares of stock ranking junior (either as to dividends or amounts payable upon
any voluntary or involuntary liquidation, dissolution or winding up) to the
Junior Participating Preferred Stock unless, prior thereto, the holders of
shares of Junior Participating Preferred Stock will have received $100.00 per
share, plus accrued and unpaid dividends to the date of such payment, provided
that the holders of shares of Junior Participating Preferred Stock will be
entitled to receive an aggregate amount per share, subject to certain
provisions for adjustment set forth in the Restated Certificate, equal to 100
times the aggregate amount to be distributed per share to holders of common
stock, or (2) to the holders of stock ranking on a parity (either as to
dividends or amounts payable upon any voluntary or involuntary liquidation,
dissolution or winding up) with the Junior Participating Preferred Stock,
except distributions made ratably on Junior Participating Preferred Stock and
all other such parity stock in proportion to the total amounts to which the
holders of all such shares are entitled upon such voluntary or involuntary
liquidation, dissolution or winding up.
 
                                      175
<PAGE>
 
  Voting Rights. Except as indicated below or as expressly required by
applicable law, the holders of Junior Participating Preferred Stock will not
have voting rights.
 
  Subject to certain provisions for adjustment set forth in the Restated
Certificate, each share of Junior Participating Preferred Stock will entitle
the holder thereof to 100 votes on all matters submitted to a vote of the
stockholders of the Company. Except as indicated below or expressly required by
applicable law, the holders of Junior Participating Preferred Stock and the
holders of shares of common stock will vote together as one class on all
matters submitted to a vote of stockholders of the Company.
 
  If the equivalent of six quarterly dividends payable on the Junior
Participating Preferred Stock or any other series of Serial Preferred Stock of
the Company have not been declared and paid or set aside for payment, whether
or not consecutive, the number of directors of the Company will be increased by
two and the holders of all such series in respect of which such a default
exists, voting as a class without regard to series, will be entitled to elect
two additional directors at the next annual meeting and each subsequent
meeting, until all cumulative dividends have been paid in full or until
noncumulative dividends have been paid regularly for at least a year.
 
  Consolidation, Merger, Etc. In the event of any consolidation, merger,
combination or other transaction in which shares of common stock are exchanged
for or changed into other stock, securities, cash or other property, each share
of Junior Participating Preferred Stock shall be similarly exchanged or changed
in an amount per share equal to 100 times the aggregate amount of stock,
securities, cash or other property, as the case may be, for or into which each
share of common stock is exchanged or changed.
 
 Preferred Share Purchase Rights
 
  A Right is associated with, and trades with, each Old Share outstanding.
Similarly, a Right will be associated with, and trade with, each New Share
outstanding. As long as the Rights are associated with the New Share, each
newly issued New Share issued by the Company, including New Shares into which
the ESOP Preferred Stock and the Series A Preferred Stock are convertible, will
include one Right. Moreover, the Rights Agreement will be amended such that a
Right will be associated with each share of ESOP Preferred Stock outstanding.
Each Right will entitle its holder to purchase one one-hundredth of a share of
Junior Participating Preferred Stock for $185 (subject to adjustment). Subject
to amendment, the Rights are not exercisable until 10 business days after any
person or group announces its beneficial ownership of 15% or more of the Common
Stock. The Rights Agreement will be amended to provide that the transactions
contemplated by the Recapitalization, including without limitation, the
issuance of the ESOP Preferred Stock and the Voting Preferred Stock to the ESOP
and the Class Pilot MEC Preferred Stock, the Class IAM Preferred Stock and the
Class SAM Preferred Stock to the respective holders thereof, will not cause the
Rights to become exercisable as a result thereof. See "THE PLAN OF
RECAPITALIZATION--Revised Governance Structure--Rights Plan."
   
  If any person or group acquires 15% or more of the New Shares outstanding,
each Right holder (except the acquiring party) has the right to receive, upon
exercise, New Shares (or, under certain circumstances, cash, property or other
Company securities) having a market value of three times the exercise price of
the Right. If, after the Rights become exercisable, the Company is involved in
a merger where it does not survive or survives with a change or exchange of its
New Shares or the Company sells or transfers more than 50% of its assets or
earning power, each Right will be exercisable for common stock of the other
party to such transaction having a market value of three times the exercise
price of the Right. The Company has the right to redeem the Rights for $.05 per
Right prior to the time that they become exercisable. The Rights will expire on
December 31, 1996.     
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Company's Board of Directors, except pursuant to
an offer conditioned on a substantial number of Rights being acquired. The
Rights should
 
                                      176
<PAGE>
 
not interfere with any merger or other business combination approved by the
Company's Board of Directors since the Rights may be redeemed or their terms
amended by the Company as described above.
 
                             STOCKHOLDER PROPOSALS
 
PROPOSAL CONCERNING CUMULATIVE VOTING
 
  Ms. Evelyn Y. Davis, Watergate Office Building, 2600 Virginia Avenue, N.W.,
Suite 215, Washington, D.C. 20037, owner of 53 Old Shares, has given notice
that she will introduce the following resolution at the Meeting:
 
    RESOLVED: "That the stockholders of UAL Corp., assembled in Annual
  Meeting in person and by proxy, hereby request the Board of Directors to
  take the necessary steps to provide for cumulative voting in the election
  of directors, which means each stockholder shall be entitled to as many
  votes as shall equal the number of shares he or she owns multiplied by the
  number of directors to be elected, and he or she may cast all of such votes
  for a single candidate, or any two or more of them as he or she may see
  fit."
 
    REASONS: "Many states have mandatory cumulative voting, so do National
  Banks."
 
    "In addition, many corporations have adopted cumulative voting."
 
    "Last year the owners of . . . shares, representing approximately 23.3%
  of shares voting, voted FOR this proposal."
 
    "If you AGREE, please mark your proxy FOR this resolution."
   
THE BOARD OF DIRECTORS OPPOSES THE ABOVE PROPOSAL     
   
  The Board structure included in the Recapitalization reflects a careful and
thoughtful balancing of interests between the employees of the Company, who as
of the Closing will beneficially own a majority of the economic and voting
power represented by the fully diluted common equity of the Company, and the
holders of the publicly traded New Shares, who at the time of Closing, will,
in effect, be minority stockholders in the Company. In particular, as the
Recapitalization is structured, the five Public Directors/1/ are elected by
the holders of the New Shares as a single cohesive group without any
structural bias in favor of any particular holder of New Shares or group of
such holders. The Board structure in the Recapitalization was heavily
negotiated and is complex, and the Board believes any additional complexity
that would be introduced through cumulative voting is both unwarranted and
inappropriate.     
   
  Cumulative voting also is undesirable because, among other things, it
introduces an opportunity for an individual holder of New Shares or group of
such holders to weight their votes and influence the Public Director election
process in a manner that may be contrary to the wishes of the holders of a
majority of the publicly-held New Shares. The Board believes that each Public
Director should serve on the Board only if he or she has been endorsed by the
holders of the New Shares as a whole. In addition, in the absence of the
Recapitalization transaction, the Board believes that the interests of the
stockholders as a whole are best served if the Board is elected by the
stockholders as a whole without cumulative voting.     
- --------
   
/1/The Board assumes that for purposes of the Recapitalization, the proposal
would apply only to the election of Public Directors, and not to the election
of any class of directors on which the holders of New Shares would not vote.

       THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE AGAINST THE PROPOSAL.
 
PROPOSAL CONCERNING CONTINGENT EXECUTIVE COMPENSATION AGREEMENTS
 
  The Board of Trustees of the National Electrical Benefit Fund, 1125 15th
Street, N.W., Washington, D.C. 20005, owner of 14,000 Old Shares, has given
notice that it will introduce the following resolution at the Meeting:
 
    BE IT RESOLVED: That the shareholders of UAL Corporation ("United" or
  "Company") request that the Board of Directors in the future refrain from
  entering into agreements providing executive compensation contingent on a
  change in control of the Company unless such agreements or arrangements are
  specifically submitted to the shareholders for approval.
 
                              SUPPORTING STATEMENT
 
    The Company has contingency employment arrangements with certain senior
  executives, including Messrs. Wolf, Pope, and Nagin, which provide
  compensation contingent upon a change in control of the Company. The
  agreements provide that if an executive's employment is involuntarily
  terminated after a change of control of the Company that executive will be
  entitled to payment of lucrative severance compensation. In the case of Mr.
  Wolf, such payments may amount to several million dollars (approximately
  $3,400,000). Both Mr. Wolf's and Mr. Pope's agreements also provide for
  vesting of unvested stock options, vesting of supplemental retirement
  credits, and certain other benefits of an unspecified nature. Mr. Nagin's
  agreement would provide payment of three times his base salary, as well as
  payment for and the vesting of certain other unspecified benefits. As
  described on pages 19, 23 & 24 of the Company's 1993 Proxy Statement, these
  so-called "golden parachutes" may amount to millions of dollars in
  guaranteed compensation for the affected executives. These employment
  agreements with the "golden parachute" provisions were adopted without
  consideration by the Company's shareholders. Golden parachutes, as defined
  in this proposal, are payments contingent on change in control.
 
    Lucrative severance pay to corporate executives triggered by a change in
  control of the corporation, commonly referred to as "golden parachutes," is
  a controversial matter. Golden parachutes introduce an inappropriate
  element of personal consideration for managers that potentially conflicts
  with their fiduciary responsibility to shareholders. We believe this may
  cause managers to operate in a manner which fails to maximize value for
  shareholders in the event of a potential takeover. Such a situation, we
  believe, is fundamentally unfair to shareholders, the ultimate owners of
  the Company. Moreover, it is our opinion that special compensation
  arrangements for a favored few executives undoubtedly has a corrosive
  impact on the morale and attitude of the remainder of employees who do not
  share such privileged status. Shareholders, as owners concerned with the
  long-term productive and financial performance of the Company, should be
  concerned with this type of disparity.
 
    A study by the United Shareholders Association also provides
  justification for the submission of golden parachute arrangements to
  shareholders for consideration. The study of 1,000 major U.S. corporations
  found that the average annualized two-year return was 20 percent higher for
  the 559 companies without such plans for management.
 
    We believe that the issue of whether the Company should, in the future,
  provide management with golden parachutes is of such critical importance
  that shareholders should make this decision. We believe shareholder
  approval is one of the best ways available to address potential conflicts
  of interest that may arise between the Board and top executives on one
  hand, and shareholders on the other hand, when a change of control is
  threatened.
 
    Accordingly, we urge your approval of this Proposal.
   
THE BOARD OF DIRECTORS OPPOSES THE ABOVE PROPOSAL     
   
  The Board of Directors believes that the best interests of the Company and
its stockholders are promoted by creating a unity of interest between Company
executives and stockholders. The Company's various benefit     
 
                                      178
<PAGE>
 
   
plans, described elsewhere in this Proxy Statement/Prospectus, promote this
unity of interest by encouraging management to own stock in the Company and to
seek other incentive awards based upon performance of the Company, as well as
individual performance. Each of the Company's current executive officers has a
significant ownership interest in the Company's common equity, and it is
expected that these policies and practices will continue following the
Recapitalization.     
   
  The Board believes that severance arrangements contingent upon a change in
control do not create a conflict as suggested by the proponents. Rather, these
arrangements encourage management to assess takeover bids, tender offers and
other potential change in control transactions objectively and with fewer
distractions. The arrangements provide management with a level of financial
security in the event of the loss of their jobs following a change of control
so management can remain attentive and dedicated to their duties to the Company
and less inclined to feel threatened or to seek positions outside the Company
in the face of a change in control.     
   
  The Compensation Committee of the Board, consisting exclusively of directors
who are not employees of the Company, as well as the non-employee directors of
the full Board, have approved the various change in control severance
arrangements for the Company's existing management, which the Board believes to
be in the best interests of the Company and its stockholders. The Board of
Directors believes that adoption of this resolution would inappropriately limit
the Board's flexibility in designing competitive compensation plans and would
adversely affect the ability of the Company to recruit and retain experienced,
effective management and to respond to changing economic and business
situations. Further, the Board believes the delays occasioned by such an
approval process are not in the best interest of the Company or its
stockholders.     
 
       THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE AGAINST THE PROPOSAL.
 
PROPOSAL CONCERNING CONFIDENTIAL VOTING
   
  The Central Pension Fund of the International Union of Operating Engineers
and Participating Employers, 4115 Chesapeake Street, N.W., Washington, D.C.
20016, owner of 4,722 Old Shares, has given notice that it will introduce the
following resolution at the Meeting:     
 
    BE IT RESOLVED: That the stockholders of United Air Lines Corporation (or
  "Company") recommend that the Board of Directors take the necessary steps
  to adopt and implement a policy of confidential voting at all meetings of
  its stockholders which includes the following provisions:
 
  1. that the voting of all proxies, consents and authorizations be secret,
     and that no such document shall be available for examination nor shall
     the vote or identity of any shareholder be disclosed except to the
     extent necessary to meet the legal requirements, if any, of the
     Company's state of incorporation;
 
  2. that the receipt, certification and tabulation of such votes shall be
     performed by independent election inspectors; and
 
  3. that confidential voting shall be suspended in the case of a proxy
     contest, where non-management groups have access to voting results.
 
                              SUPPORTING STATEMENT
 
    It is the proponents' belief that it is vitally important that a system
  of confidential proxy voting be established at the Company. Confidential
  balloting is a basic tenet of our political electoral process ensuring its
  integrity. The integrity of corporate board elections should also be
  protected against potential abuses given the importance of corporate
  policies and practices to corporate owners and our national economy.
 
                                      179
<PAGE>
 
    The implementation of a confidential voting system would enhance
  shareholder rights in several ways. First, in protecting the
  confidentiality of the corporate ballot, shareholders would feel free to
  oppose management nominees and issue positions without fear of retribution.
  This is especially important for professional money managers whose business
  relationships can be jeopardized by their voting positions.
 
    The second important benefit of confidential voting would be to
  invigorate the corporate governance process at the Company. We believe that
  shareholder activism would be promoted within the Company. It is our belief
  that shareholders empowered with a free and protected vote would be more
  active in the proposing of corporate policy resolutions and alternate board
  candidates.
 
    Finally, it is our belief that the enhancement of the proxy voting
  process would change the system where too often shareholders vote "with
  their feet" not with their ballots. This change would help to develop a
  long-term investment perspective where corporate assets could be deployed
  and used in a more effective and efficient manner.
 
    Confidential voting is gaining popularity. By 1993, 94 major U.S.
  publicly-traded companies had adopted confidential proxy voting procedures
  for corporate elections, up from 74 in 1992. The list of Fortune 500
  companies with confidential voting includes: AT&T, U.S. West, American
  Express, American Brands, Coca Cola, CitiCorp., Gillette, Exxon, Sara Lee,
  J.P. Morgan, Bear Stearns, General Electric, General Mills, General Motors,
  Colgate-Palmolive, American Home Products, Honeywell, Avon Products, 3M,
  DuPont, Boeing, Lockheed, Rockwell International, Amoco, Mobil, Eastman
  Kodak, IBM, Xerox and many others. It's time for the Company to do the
  same.
 
    For the reasons outlined above, we urge you to VOTE FOR THIS PROPOSAL.
   
THE BOARD OF DIRECTORS OPPOSES THE ABOVE PROPOSAL     
   
  The Board of Directors believes that the Company's existing procedures for
submitting proxies and conducting balloting are appropriate, have worked well
and should not be changed. The proposal suggests that there is a problem when
the Board of Directors in fact believes that none exists.     
   
  The Company conducts its stockholder votes in accordance with all applicable
legal requirements, including the use of an independent inspector of election
for tabulating ballots and reporting on election results. Thus, the second part
of the proposal would add nothing to the Company's existing practice.     
   
  The Board of Directors believes that a requirement of confidential voting
would undermine a valuable means of communication between the Company and its
stockholders. Over the years, a number of stockholders have expressed comments
and opinions by writing notes on their proxy cards. These comments are reviewed
and taken into consideration like any other communications from our
stockholders.     
   
  The Board of Directors believes that from time to time circumstances may
arise in which it would be appropriate and desirable to know how stockholders
are voting and sees no reason to restrict its discretion in this regard. For
example, an occasion could arise in which the Board believes that stockholders
have been confused on a particular issue and that it would be appropriate to
engage in discussions or other communications with such stockholders in order
to address any misunderstandings. Such a dialogue would help ensure that all
stockholders are adequately informed on important matters that they have been
asked to consider.     
   
  The Board of Directors believes that the proposal is unnecessary because any
stockholder who wishes to cast a confidential vote may do so under the current
voting system simply by registering his or her shares in the name of a bank,
broker or other nominee. Nominee holders do not disclose the names of
beneficial owners without the owner's permission.     
 
       THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE AGAINST THE PROPOSAL.

                         INDEPENDENT PUBLIC ACCOUNTANTS
 
  The Board, at the recommendation of the Audit Committee, has appointed,
subject to approval by the stockholders, the firm of Arthur Andersen & Co., as
independent public accountants, to examine the financial statements of the
Company for the year 1994. It is anticipated that a representative of Arthur
Andersen & Co. will be present at the meeting and will have the opportunity to
make a statement, if he desires to do so, and will be available to respond to
appropriate questions at that time.
 
  The affirmative vote of a majority of Old Shares present at the meeting is
necessary for approval of this proposal. If the stockholders do not approve the
appointment of Arthur Andersen & Co., the selection of independent public
accountants will be reconsidered by the Board.
 
  THE BOARD RECOMMENDS A VOTE FOR THE APPROVAL OF THE APPOINTMENT OF ARTHUR
ANDERSEN & CO. AS INDEPENDENT PUBLIC ACCOUNTANTS FOR THE COMPANY FOR 1994.
 
                       DISCRETIONARY AUTHORITY OF PROXIES
 
  The Board of Directors of the Company does not know of any matters, other
than as described in the Notice of Meeting attached to this Proxy
Statement/Prospectus, that are to come before the Meeting. If a proxy is given
to vote in favor of the Plan of Recapitalization, the persons named in such
proxy will have authority to vote in accordance with their best judgment on any
other matter that is properly presented at the Meeting for action, including,
without limitation, any proposal to adjourn the Meeting or otherwise concerning
the conduct of the Meeting.
 
  In the event that a quorum is not present at the time the Meeting is
convened, or if for any other reason the Company believes that additional time
should be allowed for the solicitation of proxies, the Company may adjourn the
Meeting with a vote of the stockholders. The persons named in the accompanying
form of proxy will vote any Shares for which they have voting authority in
favor of such adjournment. The Company has made no determination whether it
would adjourn the Meeting to allow additional time for the solicitation
 
                                      181

of proxies should an insufficient number of favorable votes be received to
approve and adopt the Plan of Recapitalization.

  The consolidated financial statements and related schedules of the Company
and United as of December 31, 1993 and 1992 and for each of the three years in
the period ended December 31, 1993, incorporated by reference in this Proxy
Statement/Prospectus and elsewhere in the Registration Statement have been
audited by Arthur Andersen & Co., independent public accountants, as indicated
in their report with respect thereto, and are incorporated by reference herein
in reliance upon the authority of said firm as experts in giving said report.
Reference is made to said report which includes an explanatory paragraph with
respect to the changes in methods of accounting for income taxes and
postretirement benefits other than pensions as discussed in the notes to the

                                 LEGAL OPINION
   
  The validity of the New Shares, Debentures, the Depositary Preferred Shares
and Public Preferred Stock issuable pursuant to the Recapitalization will be
passed upon by Skadden, Arps, Slate, Meagher & Flom. Such counsel have assumed
that the Company will not be rendered insolvent as a result of the
Recapitalization.     
 
                               PROXY SOLICITATION
 
  Proxies are being solicited by and on behalf of the Board. All expenses of
this solicitation including the cost of preparing and mailing this Proxy
Statement/Prospectus will be borne by the Company. In addition to solicitation
by use of the mails, proxies may be solicited by directors, officers and
employees of the Company in person or by telephone, telegram or other means of
communication. Such directors, officers and employees will not be additionally
compensated, but may be reimbursed for out-of-pocket expenses, in connection
with such solicitation. Arrangements will also be made with custodians,
nominees and fiduciaries for forwarding of proxy solicitation material to
beneficial owners of Old Shares held of record by such persons, and the Company
may reimburse such custodians, nominees and fiduciaries for reasonable expenses
incurred in connection therewith. To assure the presence in person or by proxy
of the largest number of stockholders possible, the Company has engaged
Georgeson & Co. to solicit proxies on behalf of the Company. The Company has
agreed to pay such firm a proxy solicitation fee of $          and to reimburse
such firm for its reasonable out-of-pocket expenses.
 
                       PROPOSALS FOR 1995 ANNUAL MEETING
   
  The Company expects to hold its 1995 Annual Meeting, in accordance with
historic practices, on the fourth Thursday in April, April 27, 1995.
Accordingly, any stockholder proposals intended to be presented at the 1995
Annual Meeting must be received by November 25, 1994, by the Secretary of the
Company (Francesca M. Maher, Secretary, UAL Corporation, P.O. Box 66919,
Chicago, Illinois 60666), in writing in accordance with rules promulgated by
the Commission.     
 
                                 OTHER MATTERS
 
  The Board does not know of any other business which may be presented for
consideration at the meeting. If any business not described herein should come
before the meeting, the persons named in the enclosed proxy will vote on those
matters in accordance with their best judgment.

perform his duties.
 
  5.11 Additional Powers and Duties. In addition to the foregoing especially
enumerated duties and powers, the officers of the Corporation shall perform
such other duties and exercise such further powers as may be provided in these
Restated Bylaws or as the Board may, from time to time, determine or as may be
assigned to them by any competent superior officer.
 
  5.12 Compensation. Except as otherwise provided in the Restated Certificate,
the compensation of all officers of the Corporation shall be fixed, from time
to time, by the Board.
 
                                   ARTICLE 6
 
                          Stock and Transfers of Stock
 
  6.1 Stock Certificates. Every Stockholder shall be entitled to a certificate
signed by the Chairman or the President or a Vice President, and by the
Treasurer or an Assistant Treasurer, or the Secretary or an Assistant
Secretary, certifying the number of shares owned by such Stockholder in the
Corporation. Any or all of the signatures on the certificate may be a
facsimile. In case any officer, Transfer Agent or Registrar who has signed or
whose facsimile signature has been placed upon a certificate shall cease to be
such officer, Transfer Agent or Registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if he were such
officer, Transfer Agent or Registrar at the date of issuance.
 
  6.2 Transfer Agents and Registrars. The Board may, in its discretion, appoint
responsible banks or trust companies in the Borough of Manhattan, in the City
of New York, State of New York, and in such other city or cities as the Board
may deem advisable, from time to time, to act as Transfer Agents and Registrars
of the stock of the Corporation; and, when such appointments shall have been
made, no stock certificate shall be valid until countersigned by one of such
Transfer Agents and registered by one of such Registrars.
 
  6.3 Transfers of Stock. Except as otherwise provided in the Restated
Certificate, and subject to any other transfer restriction applicable thereto,
shares of stock may be transferred by delivery of the certificates therefor,
accompanied either by an assignment in writing on the back of the certificates
or by written power of attorney to sell, assign and transfer the same, signed
by the record holder thereof; but no transfer shall affect the right of the
Corporation to pay any dividend upon the stock to the holder of record thereof,
or to treat the holder of record as the holder in fact thereof for all
purposes, and no transfer shall be valid, except between the parties thereto,
until such transfer shall have been made upon the books of the Corporation.
 
  6.4 Lost Certificates. In case any certificate of stock shall be lost, stolen
or destroyed, the Board, in its discretion, may authorize the issuance of a
substitute certificate in place of the certificate so lost, stolen or destroyed
and may cause such substitute certificate to be countersigned by the
appropriate Transfer Agent (if any) and registered by the appropriate Registrar
(if any); provided, that, in each such case, the applicant for a substitute
certificate shall furnish to the Corporation and to such of its Transfer Agents
and Registrars as
 
                                       10

may require the same, evidence to their satisfaction, in their discretion, of
the loss, theft or destruction of such certificate and of the ownership
thereof, and also such security or indemnity as may be required by them.
 
  6.5 Record Date.
 
  (a) In order that the Corporation may determine the Stockholders entitled to
notice of or to vote at any meeting of Stockholders or any adjournment thereof,
or, subject to applicable law, to express consent to corporate action in
writing without a meeting, or entitled to receive payment of any dividend or
other distribution or allotment of any rights, or entitled to exercise any
rights in respect of any change, conversion or exchange of stock or for the
purpose of any other lawful action, the Board is authorized, from time to time,
to fix, in advance, a record date, which shall not be more than sixty nor less
than ten days before the date of such meeting, nor more than sixty days prior
to any other action.
 
  (b) A determination of Stockholders of record entitled to notice of or to
vote at a meeting of Stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board may fix a new record date for the
adjourned meeting.
 
                                   ARTICLE 7
 
                                 Miscellaneous
 
  7.1 Fiscal Year. The fiscal year of the Corporation shall be the calendar
year.
 
  7.2 Surety Bonds. The Treasurer, each Assistant Treasurer and such other
officers or agents of the Corporation as the Board may direct, from time to
time, shall be bonded for the faithful performance of their duties in such
amounts and by such surety companies as the Board may determine. The premiums
on such bonds shall be paid by the Corporation and the bonds so furnished shall
be in the custody of the Chief Executive Officer.
 
  7.3 Signature of Negotiable Instruments. All bills, notes, checks or other
instruments for the payment of money shall be signed or countersigned by such
officer or officers and in such manner as, from time to time, may be prescribed
by resolution (whether general or special) of the Board.
 
                                   ARTICLE 8
 
                                   Amendments
 
  8.1 Amendment of these Restated Bylaws Prior to the Termination Date. Until
the Termination Date, notwithstanding that a lesser or no vote of either the
Board or the Stockholders may be required by applicable law, and in addition to
any other vote of the Board or the Stockholders required by applicable law or
the Restated Certificate, (a) any Substantive Amendment to these Restated
Bylaws shall be effected as provided in the Restated Certificate and (b) any

thereof, at which a quorum is present, the notice of which meeting shall
include the form of the proposed amendment or supplement to or modification of
these Restated Bylaws or of the proposed new bylaws, or a summary thereof.*

                                     PART I
 
ITEM 1. BUSINESS
 
 Introduction
 
  UAL Corporation ("UAL" or the "Company") was incorporated under the laws of
the State of Delaware on December 30, 1968. The executive offices of the
Company are located at 1200 Algonquin Road, Elk Grove Township, Illinois 60007.
The Company's mailing address is P.O. Box 66919, Chicago, Illinois 60666. The
telephone number for the Company is (708) 952-4000.
 
  The Company is a holding company and its principal subsidiary is United Air
Lines, Inc. ("United"), which is wholly-owned. United accounted for virtually
all of the Company's revenues and expenses in 1993. United is a major
commercial air transportation company. Mileage Plus, Inc., which is also
wholly-owned by the Company, administers frequent flyer bonus programs for
United. During 1993, the Company transferred substantially all of the operating
assets of Air Wisconsin, Inc., a regional airline indirectly owned by the
Company through another wholly-owned subsidiary, Air Wis Services, Inc. (see
Item 2, Properties, "Transfers of Assets").
 
 Proposed Employee Investment Transaction
 
  On December 22, 1993, the Board of Directors of the Company approved an
agreement in principle (as amended, the "Agreement in Principle") with the Air
Line Pilots Association ("ALPA") and the International Association of
Machinists ("IAM") concerning a proposed transaction (the "Employee Investment
Transaction") that would provide a majority equity interest in the Company to
certain of the employees of United in exchange for wage and benefit concessions
and work-rule changes. In January 1994, ALPA and the IAM ratified the Agreement
in Principle. The Employee Investment Transaction is subject to, among other
conditions, execution of definitive documentation and approval by the Company's
stockholders.
 
  The proposed Employee Investment Transaction is intended to put in place a
lower cost structure that allows United to compete effectively in domestic
markets and improve its long-term financial competitiveness. The concessions
would come from three of United's employee groups: employees represented by
ALPA, employees represented by the IAM, and the salaried and management
employees. Employees represented by the Association of Flight Attendants
("AFA") have been invited to participate in the transaction, and
representatives of the Company have engaged in discussions with AFA
representatives concerning such participation but the transaction does not
require their participation to proceed.
 
  In the proposed transaction, an employee stock ownership plan ("ESOP") would
be created to provide United employees with a minimum of a 53% equity interest
in the Company in exchange for wage and benefit concessions and work-rule
changes. The employee interest could increase to up to 63%, depending on the
average market value of the Company's common stock in the year after the
transaction closes. The transaction would not be dependent on external
financing.
 
  Pursuant to the terms of the Agreement In Principle, current stockholders of
the Company would receive the remaining 37% to 47% of the new common stock and
$88 per share of cash and face amount of debt and preferred stock. The
transaction would provide for the creation of a low-cost short-haul operation
to compete in domestic markets. For additional information concerning the
Agreement in Principle and the proposed Employee Investment Transaction, see
Item 7, "Management's Discussion and Analysis of Financial Condition and
Results of Operation".

 Recent Developments
 
  In January 1994, United entered into an agreement with The Boeing Company
("Boeing") to acquire two new B747-400 aircraft in 1994, in place of options
for two similar aircraft (see "Flight Equipment" in Item 2, Properties).
 
  In March 1994, United opened a new major aircraft maintenance and overhaul
facility ("MOC-II") in Indianapolis. Operating under a lease with the
Indianapolis Airport Authority which expires November 30, 2031, when all phases
of the construction work are completed United will occupy approximately 300
acres of land and up to three million square feet of space, including 15
aircraft dock positions. MOC-II will be used for maintenance of Boeing 737
aircraft, engine repair, spare parts storage, ground equipment maintenance,
technical support and administrative functions.
 
 Airline Operations
 
  United has been engaged in the air transportation of persons, property and
mail since 1934, and certain of its predecessors began operations as early as
1926. United is one of the world's largest investor-owned airlines as measured
by operating revenues, revenue passengers and revenue passenger miles flown. At
the end of 1993, United served 159 airports in the United States and 32 foreign
countries. During 1993, United averaged 2,040 departures daily, flew a total of
101 billion revenue passenger miles, and carried an average of 191,000
passengers per day.
 
  United provides service to its domestic and international markets principally
through a system of hub airports at major cities. Each hub provides United
flights to a network of spoke destinations as well as flights to other United
hubs. This arrangement permits travelers to fly from point of origin to more
destinations without switching carriers. Currently, United flies from four U.S.
hubs--Chicago-O'Hare International ("O'Hare"), Denver, San Francisco
International, and Dulles International near Washington, D.C. ("Dulles")--and
is the principal carrier at each of these hubs. United also has a Pacific hub
operation at Tokyo Narita airport, and an Atlantic hub operation at London
Heathrow Airport. During the last several years, United has strengthened the
revenue-generating capability of the hub airports by: (1) adding new spokes
(new cities and airports); (2) adding frequency on previously operated route
segments; and (3) entering into marketing agreements with smaller U.S. air
carriers which serve less populated destinations and with foreign carriers
which serve destinations that United could not serve economically itself.
 
  United has developed a route system covering North America, Asia, the South
Pacific, Europe and Latin America.
 
  Within North America, East-West traffic is served by nonstop Transcontinental
flights and by the hubs at Chicago O'Hare and Denver, while North-South traffic
on the West Coast is served by the San Francisco hub.
 
  Within North America, United has a marketing program with selected
independent regional air carriers, known as the United Express ("UE") program,
which allows United to increase the number of destinations served by its hub-
and-spoke network. Six regional carriers currently participate in the UE
marketing program providing connecting schedules to ten major cities also
served by United: Air Wisconsin Airlines Corporation to Chicago and Denver;
UFS, Inc. to Chicago; Mesa Airlines, Inc. to Denver and Los Angeles; WestAir
Commuter Airlines, Inc. to San Francisco, Los Angeles, Seattle and Portland,
Oregon; Great Lakes Aviation to Chicago, Denver and Minneapolis; and Atlantic
Coast Airlines, Inc. to Washington-Dulles, Newark and Orlando. Connecting
schedules of three of these carriers result in part from separate transfers to
them in 1993 of operating assets of Air Wisconsin, Inc. (see Item 2,
Properties, "Transfers of Assets").
 
  Within North America, United also has marketing agreements that provide for
sharing of the "UA" code on certain routes with two other domestic air
carriers, Trans World Express ("TWE") and Aloha Airlines. Code-sharing allows
an airline to expand the marketing of its service brand by using its two-letter
 
                                       3
<PAGE>
 
designator code to designate in computerized reservations systems a connecting
flight operated by another airline on the itinerary. Under these agreements,
the UA designator code is reflected on TWE flights between approximately 20
cities in the Northeast U.S. which connect with United's international flights
in and out of New York John F. Kennedy International Airport ("Kennedy"), and
on Aloha Airlines' flights between and among the Hawaiian Islands in connection
with United's flights in and out of Hawaii. Finally, North American traffic is
also served by code-sharing agreements United has with two Caribbean air
carriers, ALM and Sunaire, under which each reflects the United designator code
on its flights.
 
  Asian traffic is served from six U.S. cities via the Tokyo hub and with
nonstop flights from San Francisco to Hong Kong, Osaka, Seoul and Taipei; from
Honolulu to Osaka; and, beginning in 1993, from Los Angeles to Hong Kong, and
from Chicago to Seoul. Effective October 1994, United plans to offer nonstop
service between Los Angeles and Osaka and, as soon as government approvals are
received, service between Los Angeles and Ho Chi Minh City, Vietnam, via
Taipei. South Pacific traffic to Auckland, Melbourne and Sydney is served from
Los Angeles. United plans to begin nonstop service between San Francisco and
Sydney beginning in June 1994 (subject to the approval of the Australian
government), further strengthening United's San Francisco international hub and
supplementing United's Los Angeles to Sydney service. United also has code-
sharing agreements with two South Pacific air carriers, Ansett Australia and
Ansett New Zealand. Based on reports filed with the Department of
Transportation, United was the leading U.S. carrier in the Pacific in 1993 in
terms of revenue passenger miles. During 1993, United's Pacific Division
accounted for 25% of United's revenues.
 
  Service between the U.S. and Europe is provided by: flights from six U.S.
cities to the London hub, with connecting service at London to several European
cities; flights from four U.S. cities to Paris, with connecting service to two
European cities; and nonstop service from Dulles to Brussels, Frankfurt,
Madrid, Milan/Rome and, beginning in 1993, to Amsterdam, Glasgow and Zurich;
and from Chicago to Frankfurt. European traffic is also served by United's
code-sharing agreements with British Midland and Emirates. In addition, in 1993
a comprehensive marketing agreement was signed with Germany's flag carrier,
Lufthansa, and is awaiting governmental approvals. If approved, this worldwide
alliance would, among other things, allow code-sharing between the two airlines
on Transatlantic route segments, and would permit United to code-share on
Lufthansa flights to eight cities in Germany beyond Frankfurt (Berlin, Cologne,
Dusseldorf, Hanover, Hamburg, Munich, Nuremberg and Stuttgart), as well as
Vienna. Similarly, the agreement would permit Lufthansa to code-share on United
flights to eleven cities in the U.S.--five beyond Chicago, five beyond
Washington, D.C., and one beyond San Francisco. A 1993 agreement to acquire
USAir's Philadelphia-London route was terminated due to the transaction's
failure to receive the requisite governmental approvals.
 
  Service between the U.S. and Latin America is provided by flights to 14 Latin
American cities in 11 countries from a number of cities in the U.S. Ten Latin
American cities are served nonstop from Miami, three nonstop from Los Angeles
and four from New York-Kennedy. United also has a code-sharing agreement with
Transbrasil.
 
  Operating revenues attributed to United's foreign operations were
approximately $5.6 billion in 1993, $4.9 billion in 1992 and $3.9 billion in
1991.

 Industry Conditions
 
  Seasonal and Other Factors. The Company's results of operations for interim
periods are not necessarily indicative of those for an entire year, since the
air travel business is subject to seasonal fluctuations. United's first and
fourth quarter results normally are affected by reduced travel demand in the
fall and winter, and United's operations, particularly at its O'Hare and Denver
hubs, are often affected adversely by winter weather. In the past, these
fluctuations have generally resulted in better operating results for United
and, thus, the Company, in the second and third quarters. See Item 8,
"Financial Statements and Supplementary Data," for summarized unaudited
financial data for the four quarters of 1993 and 1992 incorporated by reference
therein.
 
  The results of operations in the air travel business have also fluctuated
significantly in the past in response to general economic conditions. In
addition, the airline business is characterized by a high degree of operating
leverage. As a result, the economic environment and small fluctuations in
United's yield per revenue passenger mile and cost per available seat mile can
have a significant impact on operating results. The Company anticipates that
seasonal factors and general economic conditions, in addition to industrywide
fare levels, labor and fuel costs, the competition from other airlines with
lower operating costs than United's international government policies, and
other factors, will continue to impact United's operations.
 
  Competition and Fares. The airline industry is highly competitive. In
domestic markets, new and existing carriers are free to initiate service on any
route. United faces competition from other carriers on
 
                                       5
<PAGE>
 
virtually every route it serves. In United's domestic markets, these
competitors include all of the other major U.S. airlines as well as smaller
carriers.
 
  United's marketing strategy is driven by four principal competitive factors:
schedule convenience, overall customer service, frequent flyer programs and
price. United seeks to attract travelers through convenient scheduling
(particularly during peak demand periods), high quality service, frequent flyer
programs designed to reward customer loyalty, and competitive pricing.
 
  During 1993, certain domestic carriers, both in and out of bankruptcy
proceedings, reorganized their operating cost structures. These carriers,
together with more recent entrants to the airline business, and a select number
of established domestic carriers, currently have cost structures significantly
lower than United's, and therefore may be able to operate profitably at lower
fare levels. Furthermore, certain carriers in the short-to-medium distance
domestic markets have been able to compete against major air carriers,
including United, by operating without as great a reliance upon a hub-and-spoke
system. These airlines operate efficiently through strategies such as rapid
turnaround of flights on a point-to-point basis. The success of these carriers
and such strategies has led certain major carriers, including United, to
consider ways in which to reorganize their short-haul operations to allow them
to compete more effectively in domestic markets.
 
  From time to time, excess aircraft capacity and other factors such as the
cash needs of financially distressed carriers induce airlines to engage in
"fare wars." Such factors can have a material adverse impact on the Company's
revenues. The Company maintains yield and inventory management programs
designed to manage the number of seats offered in various fare categories in
order to enhance the effectiveness of fare promotions and maximize revenue
production on each flight.
 
  In order to improve its ability to compete effectively in the markets that it
serves, United has taken several steps to reduce its costs and capital
expenditures. In January 1993, United announced a cost reduction program, which
included the layoff of 2,800 employees in February 1993. In 1993 United reached
agreement with Boeing to convert 49 Boeing aircraft orders into options and
delay delivery of certain of the Boeing aircraft. United also reached agreement
with Airbus Industrie ("Airbus") to delay delivery of 14 A320s originally
scheduled for delivery after 1994. In addition, United announced in 1993 that
it would accelerate the retirement of 25 widebody aircraft. United also
negotiated over $100 million in annual savings from suppliers. Finally, in 1993
United reached agreements to sell assets related to the operation of 16 of its
flight kitchens to Dobbs International Services, Inc. and Caterair
International Corp. for $119 million in a series of phased closings which are
expected to be completed by mid-1994.
 
  The Employee Investment Transaction, if consummated, contemplates the
creation of a low-cost, short-haul operation within United to compete more
effectively in domestic markets and improve its long-term financial competitive
position.
 
  In its international markets, United competes with major U.S. carriers as
well as investor-owned and national flag carriers of foreign countries.
Competition in certain international markets is subject to varying degrees of
governmental regulation (see "Government Regulation"), and in certain instances
United's foreign competitors enjoy subsidies and other forms of governmental
support which are not available to U.S. carriers.
 
  United and other U.S. carriers have certain advantages over foreign air
carriers in their ability to generate U.S.-origin-destination traffic from
their integrated domestic route systems. However, the U.S. carriers are in many
cases constrained from carrying passengers to points beyond designated gateway
cities in foreign countries due to limitations in the bilateral air service
agreements with such countries or restrictions imposed unilaterally by the
foreign governments. To the extent that foreign competitors can offer more
connecting services to points beyond these gateway cities, they have an
advantage in attracting traffic moving between these foreign points and in
attracting traffic moving between such cities and points in the United States.
Also, several foreign air carriers have sought and obtained access to the U.S.
domestic market through substantial
 
                                       6
<PAGE>
 
equity investments and code sharing arrangements with U.S. airlines. The
comprehensive marketing agreement signed in 1993 with Germany's flag carrier,
Lufthansa, if approved, is also expected to enhance the Company's competitive
position in international markets.
 
  No material part of the business of United, or of the Company and its
subsidiaries, is dependent upon a single customer or very few customers.
Consequently, the loss of the few largest customers of United, or of the
Company, would not have a material adverse effect on the Company.
 
  Airport Access. United's operations at its principal domestic hub, Chicago-
O'Hare International Airport ("O'Hare"), as well as at three other airports,
Kennedy, New York LaGuardia ("LaGuardia"), and Washington National
("National"), are limited by the "high density traffic airports rule"
administered by the Federal Aviation Administration ("FAA"). Under this rule,
take-off and landing rights ("slots") required for the conduct of domestic
flight operations may be bought, sold or traded. As of December 31, 1993,
United held 753 domestic air carrier slots at O'Hare, 43 at National, 65 at
LaGuardia and 11 at Kennedy. In addition, Air Wisconsin, Inc. held (or owned
the beneficial interest in) 38 air carrier slots and 118 commuter slots at
O'Hare which are either operated by United or leased to United Express carriers
serving O'Hare. Under the high density rule carriers are required to relinquish
slots to the FAA for reallocation if they fail to meet certain minimum use
standards.
 
  Slots for international services at O'Hare are allocated by the FAA
seasonally to both U.S. and foreign carriers based upon the carriers'
historical operations and requests for additional capacity. The FAA holds a
certain number of slots in reserve for this purpose. Slots over that number are
provided through the withdrawal of domestic slots from carriers at O'Hare and
the reallocation of those slots for international operations of requesting
carriers. United has lost as many as 33 daily slots--that is, slots that were
being used by United three days or more per week--during a single operating
season.
 
  During 1993, Congress amended the U.S. Department of Transportation ("DOT")
appropriations bill for fiscal year 1994. This legislation capped for that
fiscal year the number of slots that could be withdrawn from U.S. carriers for
allocation to international operations. Also, in November 1991, United
petitioned the FAA for a repeal of the international slot withdrawal provisions
of the regulations. This petition has not, however, been acted upon by the
agency. United believes that the number and distribution of slots it holds at
the airports subject to the high density rule are sufficient to support its
current operations. There can be no assurance, however, that additional slots
sufficient to accommodate otherwise desirable service expansions will be
available to United on satisfactory terms in the future. There is also no
assurance that the current slot regulations will remain in effect. If an
alternative to the current system were to be adopted, no assurance can be given
that such alternative would preserve United's investment in slots already
acquired or that slots adequate for future operations would be available.
 
  United believes that, at present, it has a sufficient number of leased gates
and other airport facilities at the cities it serves to meet its current and
near term needs. From time to time, expansion by United at certain airports may
be constrained by insufficient availability of gates on attractive terms.
United's ability to expand its international operations in Asia, the South
Pacific, Europe and Latin America is subject to restrictions at many of the
airports in these regions, including noise curfews, slot controls and absence
of adequate airport facilities.
 
  At Los Angeles and elsewhere, United and other airlines face continuing
disputes as to the level of landing fee rates and other charges for airport
operations. Recently, some of these rates and charges have escalated rapidly.
 
  Mileage Plus Program. United operates a frequent flyer marketing program
known as "Mileage Plus" wherein credits are earned by flying on United or using
the services of one of the other airlines, credit card companies, car rental
agencies and hotels (the "Partners") participating in the Mileage Plus program.
The program is designed to enable United to retain and increase the business of
frequent travelers. Credits earned
 
                                       7
<PAGE>
 
under the program may be exchanged at certain plateaus for free travel or
service upgrades on United or for use with one or more of the Partners.
 
  When an award level is attained, United records a liability for the
incremental costs of accrued credits under the Mileage Plus program based on
the expected redemptions. United's incremental costs include the costs of
providing service for an otherwise vacant seat including fuel, meals, certain
incremental personnel and ticketing costs. The incremental costs do not include
any contribution to overhead or profit. Awards earned after July 1989 have an
expiration date three years from date earned. The program also contains certain
restrictive provisions, including blackout dates and capacity controlled
bookings, which substantially limit the use of the awards on certain flights.
 
  In 1993 United announced that the mileage levels for Mileage Plus domestic
award travel would be increased on a prospective basis. As revised in January
1994, the Mileage Plus rules will require 25,000 miles, instead of the 20,000
miles now required, for award tickets issued for economy class travel within
the continental United States. Other mileage award level changes were also
announced, as was a change to a bank-account type of system to track mileage;
all changes are scheduled to take effect February 1, 1995.
 
  Lawsuits challenging these changes and changes to American Airlines' frequent
flyer program are pending in Illinois. While United believes that it has the
right to make the aforementioned changes to its program, and is defending
itself vigorously in the pending litigation, an adverse court decision could
restrict United's ability to alter award levels now or in the future.
 
  At December 31, 1993 and 1992, United estimated that the total number of
outstanding awards was approximately 7.7 million and 7.4 million, respectively.
United estimated that 5.8 million and 5.5 million, respectively, of such awards
could be expected to be redeemed and, accordingly, had recorded a liability
amounting to $205 million and $207 million, respectively, at December 31, 1993
and 1992. The difference between the awards expected to be redeemed and the
total awards outstanding is the estimate, based on historical data, of awards
(1) which will never be redeemed, (2) which will be redeemed for other than
free trips, or (3) which will be redeemed on partner carriers.
 
  The number of awards used on United were 1.6 million, 1.4 million and 1.6
million for the years 1993, 1992 and 1991, respectively. Such awards
represented 7.5%, 6.7% and 6.7% of United's total revenue passenger miles for
each period, respectively. With these low percentages, seat availability and
restrictions on the use of free travel awards, United believes that the
displacement, if any, of revenue passengers by users of Mileage Plus awards is
minimal.
 
  United has agreements with certain air carriers and other parties to utilize
the Mileage Plus program and receives and makes payments based on the earning
and redemption of awards by Mileage Plus participants with such parties.
 
  Computer Reservations Systems. Travel agents account for a substantial
percentage of United's sales. The complexity of the various schedules and fares
offered by air carriers has fostered the development of electronic distribution
systems that display information relating the fares and schedules of United and
other airlines to travel agents and others. United believes that the use of
such systems has been a key factor in the marketing and distribution of
airlines' products.
 
  Before September 1993, United had an ownership interest in two general
partnerships which owned and marketed computer reservation system ("CRS")
products and services. In September 1993, The Covia Partnership ("Covia"), a
50%-owned affiliate of United, and The Galileo Company Limited, a 25.6%-owned
affiliate of United, combined. In the combination Covia was renamed as "Galileo
International Partnership" ("Galileo"), and a second entity, the Apollo Travel
Services Partnership ("ATS"), was formed. These two general partnerships are
owned 38% and 77%, respectively, by United through a wholly-owned subsidiary.
 
 
                                       8
<PAGE>
 
  Galileo is held 50% by European carriers and 50% by North American carriers.
It owns the Apollo and Galileo CRSs and markets CRS services worldwide through
a system of national distribution companies located in countries in which
Galileo operates and which are usually owned by the Galileo partner airline
resident in a particular country, or if there is none, by Galileo or a local
contractor. Galileo is used by approximately 30% of the travel agent locations
outside North America, where it has over 42,000 terminals at more than 14,000
locations.
 
  ATS, which is held solely by the North American carriers, is responsible for
marketing, sales and support of Apollo CRS products and services in the United
States, Mexico and the Caribbean. A third entity, Galileo Japan Partnership, a
50%-owned affiliate of United, was also formed in September 1993 for the
purpose of distributing CRS services in Japan.
 
  In Canada, Apollo is distributed as the "Apollo by Gemini" product sold by
the Gemini Group Limited Partnership ("Gemini"), in which Galileo owned a one-
third interest. Gemini is under a court order to dissolve by November 1994, and
Air Canada has agreed to acquire Galileo's interest in Gemini. Galileo is in
discussions concerning an alternative distribution of its CRS products and
services in Canada.
 
  Competition among CRS vendors is intense, and services similar to these
offered by Galileo are marketed by several air carriers and other concerns,
both in the United States and worldwide. In the European and Pacific CRS
markets, various consortia of foreign carriers have formed CRSs to be marketed
in countries in which the owning carriers have a substantial presence.
 
 Government Regulation
 
  General. All carriers engaged in air transportation in the United States,
including United, are subject to regulation by the DOT and the FAA under the
Federal Aviation Act of 1958, as amended (the "Aviation Act"). The DOT has
authority to regulate certain economic and consumer protection aspects of air
transportation. It is empowered to issue certificates of public convenience and
necessity for domestic air transportation upon a carrier's showing of fitness;
to prohibit unjust discrimination; to prescribe forms of accounts and require
reports from air carriers; to regulate methods of competition, including the
provision and use of computerized reservation systems; and to administer
regulations providing for consumer protection, including regulations governing
the accessibility of air transportation facilities for handicapped individuals.
United's operations require certificates of public convenience and necessity
issued by the DOT, an air carrier operating certificate and related operations
specifications issued by the FAA.
 
  United's operations also require licenses issued by the aviation authorities
of the foreign countries United serves. Foreign aviation authorities may from
time to time impose a greater degree of economic regulation than exists with
respect to United domestic operations.
 
  In international markets, United competes against foreign investor-owned and
national flag carriers and U.S. carriers that have been granted authority to
provide scheduled passenger and freight service between points in the United
States and various overseas destinations. In connection with its international
services, United is required to file with the DOT and observe tariffs
establishing the fares and rates charged and the rules governing the
transportation provided. In addition, United's operating authorities in
international markets are governed by the aviation agreements between the
United States and foreign countries.
 
  In certain cases, fares, rates and schedules require the approval of the DOT
and the relevant foreign governments. United has recommended to the U.S.
Congress that it consider developing an international aviation policy that
seeks enhanced access to international markets for U.S. carriers in return for
access to U.S. markets by foreign carriers. Shifts in United States or foreign
government aviation policies can lead to the alteration or termination of
existing air service agreements that the U.S. has with other governments, which
could diminish the value of United's international routes. For example, in 1993
the DOT determined that the Government of Japan violated its aviation agreement
with the U.S. when it prevented United from implementing service between Tokyo
and Sydney as part of United's New York-Tokyo-Sydney schedule. The DOT is
considering various actions against Japan. While such disputes are generally
the subject of inter-
 
                                       9
<PAGE>
 
governmental negotiations, there are no assurances that United's operating
rights under the bilateral aviation agreements and DOT- issued certificates of
public convenience and necessity can be preserved in such cases.
 
  The DOT and the U.S. Congress have engaged from time to time in various
regulatory and legislative initiatives, respectively, with respect to CRS
activities and issues, such as the level of booking fees, host versus non-host
functionality, mandatory dehosting, travel agency connection of third-party
hardware and software to a CRS, terms of the contracts between CRS vendors and
travel agencies, continued airline ownership of CRS vendors, and the ability to
access multiple CRS systems from a single computer terminal. New regulatory or
legislative initiatives in many of these areas, if enacted, could have a
material adverse effect upon CRS vendors in general and ATS and United in
particular.
 
  Safety. The FAA has regulatory jurisdiction over flight operations generally,
including equipment, ground facilities, maintenance, communications and other
matters. In order to ensure compliance with its operational and safety
standards, the FAA requires air carriers to obtain operating, airworthiness and
other certificates.
 
  United's aircraft and engines are maintained in accordance with the standards
and procedures recommended and approved by the manufacturers and the FAA. For
all of its engines, United utilizes a "condition monitoring" maintenance
program so that the schedule for engine removals and overhauls is based on
performance trend monitoring of engine operating data. In addition, all engines
contain time-limited components, each of which has a maximum amount of time
(measured by operating hours) or a maximum number of operating cycles (measured
by takeoffs and landings) after which the component must be removed from the
engine assembly and overhauled or scrapped. Similarly, United's FAA-approved
maintenance program specifies the number of hours or operating cycles between
inspections and overhauls of the airframes and their component parts. The
nature and extent of each inspection and overhaul is specifically prescribed by
the approved maintenance program.
 
  From time to time, the FAA issues airworthiness directives ("ADs") which
require air carriers to undertake inspections and to make unscheduled
modifications and improvements on aircraft, engines and related components and
parts. The ADs sometimes cause United to incur substantial, unplanned expense
and occasionally aircraft or engines must be removed from service prematurely
in order to undergo mandated inspections or modifications on an accelerated
basis. The issuance of any particular AD may have a greater or lesser impact on
United compared to its competitors depending upon the equipment covered by the
directive.
 
  Since 1988 the airlines, in cooperation with the FAA, have been engaged in an
in-depth review of the adequacy of existing maintenance procedures applicable
to older versions of most of the aircraft types in general use in the airline
industry. These include certain of the Boeing and Douglas aircraft used by
United. As a part of this program, the FAA has issued ADs requiring interim
inspections and remedial maintenance procedures. While certain of these aging
aircraft ADs have necessitated unscheduled removals from service and increased
maintenance costs, compliance is not expected to have a material adverse impact
on United's costs or operations.
 
  Legislation enacted by the U.S. Congress required the installation, in all
types of aircraft operated by United, of a traffic collision avoidance system
(TCAS) by November 30, 1993, and a windshear detection system by December 30,
1993. United completed the installations of both systems prior to their
respective mandated deadline dates on all aircraft operated by it.
 
  Both the DOT and the FAA have authority to institute administrative and
judicial proceedings to enforce the Aviation Act and their own regulations,
rules and orders. Both civil and criminal sanctions may be assessed for
violations. The Aviation Act provides for the assessment of civil penalties in
amounts of up to $10,000 per violation which are applicable to most cases
involving the safety of commercial aircraft operations, including the airport
security responsibilities of air carriers.
 
                                       10

  Environmental Regulations. The Airport Noise and Capacity Act of 1990
("ANCA") requires the phase-out by December 31, 1999 of Stage 2 aircraft
operations, subject to certain waivers. The FAA has issued final regulations
which would require carriers to modify or reduce the number of Stage 2 aircraft
operated by 25% by December 31, 1994, 50% by December 31, 1996, 75% by December
31, 1998 and 100% by December 31, 1999. Alternatively, a carrier could satisfy
compliance requirements by operating a fleet that is at least 55% Stage 3 by
December 31, 1994, 65% Stage 3 by December 31, 1996, 75% Stage 3 by December
31, 1998 and 100% Stage 3 by December 31, 1999. At December 31, 1993, United
operated 371 Stage 3 aircraft representing 70% of United's total fleet, and
thus is in compliance with these regulations.
 
  The ANCA recognizes the rights of operators of airports with noise problems
to implement local noise abatement procedures so long as such procedures do not
interfere unreasonably with interstate or foreign commerce or the national air
transportation system. ANCA generally requires FAA approval of local noise
restrictions on Stage 3 aircraft first effective after October 1990, and
establishes a regulatory notice and review process for local restrictions on
Stage 2 aircraft first proposed after October 1990. While United has had
sufficient scheduling flexibility to accommodate local noise restrictions
imposed to the present, United's operations could be adversely affected if
locally-imposed regulations become more restrictive or widespread.
 
  Federal Aviation Regulation Part 150, which was issued pursuant to Title I of
the Aviation Safety and Noise Abatement Act of 1979, provides limited funding
to airport operators to formulate noise compatibility programs, and established
procedures through which such programs may be approved by the FAA. This rule
may encourage the consideration of additional local aircraft and airport usage
restrictions.
 
  The Environmental Protection Agency regulates operations, including air
carrier operations, which affect the quality of air in the United States.
United has made all necessary modifications to its operating fleet to meet
emission standards issued by the Environmental Protection Agency ("EPA").
 
  Federal and state environmental laws require that underground storage tanks
(USTs) be upgraded to new construction standards and equipped with leak
detection by December 22, 1998. These requirements are phased into effect based
on the age, construction and use of existing tanks. United operates a number of
underground and above ground storage tanks throughout its system, primarily
used for the storage of fuels and deicing fluids. A program for the removal or
upgrading of USTs and remediation of any related contamination has been ongoing
since 1987. Compliance with these federal and state UST regulations is not
expected to have a material adverse effect on United's financial condition.
 
  United has been identified by the EPA as a potentially responsible party with
respect to Superfund sites involving soil and groundwater contamination at the
Bay Area Drum Site in San Francisco, California, the Chemsol, Inc. Site in
Piscataway, New Jersey, the Petrochem/Ekotek Site in Salt Lake City, Utah, the
Monterey Park Site at Monterey Park, California, the West Contra Costa Sanitary
Landfill Site in Richmond, California, and the Douglasville Site in Berks
County, Pennsylvania. Because of the limited nature of the volume of pollutants
allegedly contributed by United to the above Superfund sites, the outcome of
these matters is not expected to have a material adverse effect on United's
financial condition.
 
  United is aware of soil and groundwater contamination present on its
leaseholds at several U.S. airports, with the most significant locations being
San Francisco International Airport, Kennedy, Seattle Tacoma International
Airport, Spokane International Airport, and Stapleton International Airport in
Denver (which is expected to close in the Spring of 1994 due to the opening of
a new airport for Denver). United is investigating these sites, assessing its
obligations under applicable environmental regulations and lease agreements,
and where appropriate remediating these sites. Remediation of these sites, for
which United may be responsible, is not expected to have a material adverse
effect on United's financial condition.
 
  Other Government Matters. Besides the DOT and the FAA, other federal agencies
with jurisdiction over certain aspects of United's operations are the
Department of Justice (Antitrust Division and Immigration and Naturalization
Service), the Equal Employment Opportunity Commission, the Occupational Safety
and
 
                                       11
<PAGE>
 
Health Administration, the Department of Labor (the Office of Federal Contract
Compliance Programs of the Employment Standards Administration), the National
Labor Relations Board, the National Mediation Board, the National
Transportation Safety Board, the Treasury Department (U.S. Customs Service),
the Federal Communications Commission (due to use of radio facilities by
aircraft), and the United States Postal Service (carriage of domestic mail). In
connection with its service to cities in other countries, United is subject to
varying degrees of regulation by foreign governments. United has no existing
obligation to the Civil Reserve Air Fleet.
 
 Fuel
 
  United's results of operations are significantly affected by the price and
availability of jet fuel. Based on 1993 fuel consumption, every $.01 change in
the average annual price-per-gallon of jet fuel caused a change of
approximately $27 million in United's annual fuel costs. The table below shows
United's fuel expenses, fuel consumption, average price per gallon and fuel as
a percent of total operating expenses for annual periods from 1989 through
1993:

Changes in fuel prices are industry-wide occurrences that benefit or harm
United's competitors as well as United. Accordingly, lower fuel prices may be
offset by increased price competition and lower revenues for all air carriers,
including United. There can be no assurance that United will be able to
increase its fares in response to any increases in fuel prices in the future.
 
  In order to assure adequate supplies of fuel and to provide a measure of
control over fuel costs, United continues to ship fuel on major pipelines,
maintains fuel storage facilities, and trades fuel to locations where it is
needed. In 1993, almost all of United's fuel was purchased under contracts with
major U.S. and international oil companies. Most of these contracts are
terminable by either party on short notice. United also purchases minor volumes
of fuel on the spot market at some domestic locations. In addition, United
purchases foreign fuel on a spot basis from the Middle East, Caribbean and Far
East. Although United has not experienced any problem with fuel availability in
the past few years and does not anticipate any in the near future, it is
impossible to predict the future availability of jet fuel. If there were major
reductions in the availability of jet fuel, United's business would be
adversely affected.
 
 Insurance
 
  United carries liability insurance of a type customary in the air
transportation industry, in amounts which it deems adequate, covering passenger
liability, public liability and property damage liability. Insurance is subject
to price fluctuations from time to time. The amount recoverable by United under
aircraft hull insurance covering all damage to its aircraft is not subject to
any deductible amount in the event of a total loss. In the event of a partial
loss, however, such recovery is subject to a per-occurrence deductible of
$1,000,000 for B747s, B757s, B767s and DC10s, $750,000 for B737-300s, and B737-
500s, and $500,000 for all other aircraft except commuter aircraft, for which
the deductible is $100,000.
 
 Employees--Labor Matters
 
  On December 31, 1993, the Company and its subsidiaries had approximately
83,400 employees, of which 81,511 were employed by United (approximately ten
percent of whom are part-time employees). Approximately 64% of United's
employees were represented by various labor organizations.

 * The flight kitchen sales (see Item 2, Properties, "Transfers of Assets")
   occurring in 1994 are expected to reduce United's number of total employees
   by more than 4,000 from December 31, 1993 levels.
** If the proposed Employee Investment Transaction is consummated, the IAM and
   the ALPA contracts each will not be open for amendment until the year 1999
   or 2000, depending on when the transaction closes and whether the AFA
   participates in the transaction.
 
  United's relations with these labor organizations are governed by the Railway
Labor Act. Under this Act, collective bargaining agreements between United and
these organizations become amendable upon the expiration of their stated term.
If either party wishes to modify the terms of any such agreement, it must
notify the other party before the contract becomes amendable. After receipt of
such notice, the parties must meet for direct negotiations and, if no agreement
is reached, either party may request that a mediator be appointed. If no
agreement is reached, the National Mediation Board may determine, at any time,
that an impasse exists and may proffer arbitration. Either party may decline to
submit to arbitration. If arbitration is rejected, a 30-day "cooling off"
period commences, following which the labor organization may strike and the
airline may resort to "self-help," including the imposition of its proposed
amendments and the hiring of replacement workers.
 
  United's wage and related costs accounted for 33% of its total operating
expenses for the twelve months ended December 31, 1993. In order to enhance its
competitive position, United has taken various steps to reduce its unit costs,
including the layoffs of 2,800 employees in February 1993, the reduction in
force which is resulting from the flight kitchen sales, reductions in non-
personnel expenses and the redeployment of certain aircraft to more profitable
airports.
 
  The long-term competitiveness of United's labor costs, and the long-term
financial stability and profitability of the Company, is expected to be improve
if the proposed Employee Investment Transaction is consummated.

* United's aircraft leases have initial terms of 4 to 26 years, and expiration
  dates range from 1994 through 2018. Under the terms of leases for 287 of the
  aircraft in the operating fleet, United has the right to purchase the aircraft
  at the end of the lease term, in some cases at fair market value and in others
  at fair market value or a percentage of cost.
 
  As of December 31, 1993, 78 of the 246 aircraft owned by United were
encumbered under transaction agreements.
 
  In 1993 United took delivery of 43 new aircraft. United acquired ten B737-
500s, four B747-400s, 16 B757-200s, eight B767-300ERs, and five A320-200s.
 
  In early 1993, United revised its capital spending plan based on reductions
in its capacity requirements for the next several years. Consistent with this
reduced capital spending plan, United reached agreement with Boeing to convert
49 firm aircraft orders into options, and to delay delivery of certain aircraft
originally scheduled for delivery between 1993 and 1996 into the 1996-1999
period. Under the terms of the agreement, if United does not elect to confirm
the delivery of these option aircraft, it will forfeit significant deposits.
United also reached agreement with Airbus to delay delivery of 14 A320s
originally scheduled for delivery after 1994. In addition, United announced in
1993 that it would accelerate the retirement of 25 widebody aircraft, including
15 DC10-10s and ten B747-SPs, retiring them prior to the end of 1994; six of
these 25 widebody aircraft (five DC10-10s and one B747-SP) were retired in
1993.
 
  As a result of these new agreements, as of December 31, 1993, United had
taken delivery of all aircraft on order, with the exception of 34 B777-200
aircraft, which are scheduled to be delivered between 1995 and 1999. In
addition to the B777-200 order, United has arrangements with Airbus and A320
engine manufacturer International Aero Engines to lease an additional 45 A320-
200 aircraft, which are scheduled for delivery through 1998. At December 31,
1993, United also had purchase options for 186 B737 aircraft, 54 B757-200
aircraft, 34 B777-200 aircraft, 52 B747-400 aircraft, 8 B767-300ER aircraft and
50 A320-200.

  In 1993 the Company entered into three transactions that transferred Air
Wisconsin, Inc. flight equipment and certain other operating assets to three of
the carriers which are participants in the UE marketing program (see Item 2,
Properties, "Transfers of Assets").
 
  In January 1994, United entered into an agreement with Boeing to acquire two
new B747-400 aircraft in 1994, in place of options for two similar aircraft.
These two aircraft orders fulfill part of United's obligation to Boeing under
the 1993 restructuring agreement described above.
 
  The following table sets forth United's firm aircraft orders, options and
expected delivery schedules as of December 31, 1993:

  * In addition, United has agreed to lease an additional 45 A320-200 aircraft.
    Deliveries of these aircraft are expected to occur between 1994 and 1998.
    Also, in January 1994, United entered into an agreement with Boeing to
    acquire two new B747-400 aircraft in 1994, in place of options for two
    similar aircraft.

 Ground Facilities
 
  In the vicinity of O'Hare, United owns a 106 acre complex consisting of over
one million square feet of office space for its executive headquarters, a
computer facility, and a training center. United operates reservation centers
in or near eight U.S. cities--Chicago, Denver, Detroit, Honolulu, Los Angeles,
San Francisco, Seattle and Washington, D.C. United also operates 133 city
ticket offices in the U.S., plus offices in the Pacific and European countries
served by United.
 
  United's Maintenance Operation Center ("MOC") at San Francisco International
Airport occupies 144 acres of land, three million square feet of floor space
and 12 aircraft hangar docks, under leases expiring in 2013. Virtually all
major aircraft and component maintenance for United's fleet occurs at the MOC,
including aircraft acceptance and flight testing, and the installation, testing
and repairing of engines, electronics, and interior fittings. United also has a
major facility at the Oakland, California airport which is dedicated to
airframe maintenance and which includes a hangar with sufficient space to
accommodate maintenance work on four wide-bodied aircraft simultaneously. As of
December 31, 1993, United employed more than 11,970 mechanics, inspectors,
engineers, and maintenance support personnel at the MOC and over 1,660 at the
Oakland facility. United also has line aircraft maintenance employees and
facilities at 36 domestic and 18 international locations.
 
  In March 1994, United opened a new major aircraft maintenance and overhaul
facility ("MOC-II") in Indianapolis. Operating under a lease with the
Indianapolis Airport Authority which expires November 30, 2031. When all phases
of the construction work are completed, as scheduled, in 2004, United will
employ 6,300 people at MOC-II, and will occupy approximately 300 acres of land
and up to three million square feet of space, including 15 aircraft dock
positions. MOC-II will be used for maintenance of Boeing 737 aircraft,
 
                                       15
<PAGE>
 
engine repair, spare parts storage, ground equipment maintenance, technical
support and administrative functions.
 
  In Spring 1994 United expects to relocate its Denver hub operations to the
new Denver International Airport. Under a new 30-year lease and use agreement,
expiring in 2023, United eventually will occupy 44 gates and over one million
square feet of exclusive terminal building space. The new airport is located
northeast of Stapleton International Airport and approximately 25 miles from
downtown Denver. Upon the opening of the new airport, Stapleton will be closed
to all aircraft operations. United's flight training center will continue to be
located near Stapleton and is under lease, including options to extend, until
2018. This flight training center consists of four buildings with a total of
300,000 square feet located on 22 acres of land adjoining Stapleton. The flight
training center accommodates 26 flight simulators and over 90 computer-based
training stations, as well as cockpit procedures trainers, autoflight system
trainers and emergency evacuation trainers.
 
  United has entered into various leases relating to its use of airport landing
areas, gates, hangar sites, terminal buildings and other airport facilities in
most of the municipalities it serves. In many cases United has constructed, at
its expense, the buildings it occupies on its leased properties. In general,
buildings and fixtures constructed by United on leased land are the property of
the lessor upon the expiration of such leases. United also has leased and
improved ticketing, sales and general office space in the downtown and outlying
areas of most of the larger cities in its system. United believes its
facilities are suitable and adequate for its current requirements. United will
continue to acquire equipment and facilities as necessary to support its
airline operations.
 
 Transfers of Assets
 
  In third quarter of 1993, United reached agreements to sell, lease or
otherwise transfer assets related to the operation of 16 of its 17 domestic
flight kitchens to Dobbs International services, Inc. and Caterair
International Corp. for $119 million in a series of phased closings that
commenced in December 1993 and are expected scheduled to continue through mid-
1994. Under the agreements, the purchasers will provide catering services for
United at the airports served by the flight kitchens for seven years.
 
  In 1993 the Company, in three separate transactions, leased or transferred
substantially all of the fight equipment and other operating assets of Air
Wisconsin, Inc. ("AW") to three regional air carriers who participate in the UE
marketing program: in April, 1993, AW's twelve DeHavilland DHC-8 aircraft and
AW's operating assets at Dulles were transferred to Atlantic Coast Airlines,
Inc.; in September, 1993, AW's nine British Aerospace BAe-ATP aircraft and AW's
O'Hare operating assets were transferred to UFS, Inc.; and in December, 1993,
AW's twelve British Aerospace BAe-146 aircraft and related operating assets in
Chicago and Denver were transferred to Air Wisconsin Airlines Corporation in a
stock transaction. AW still has an operating certificate from the FAA, but
currently AW does not have any flight operations.
 
ITEM 3. LEGAL PROCEEDINGS
 
  The Company is involved from time to time in legal proceedings incidental to
the ordinary course of its business. Such proceedings include claims brought by
and against the Company or its subsidiaries including claims seeking
substantial compensatory and punitive damages. Such claims arise from routine
commercial disputes as well as incidents resulting in bodily injury and damage
to property. The Company believes that the potential liabilities in all of
bodily injury and property damage actions are adequately insured and none of
the other actions are expected to have any material adverse effect on the
Company or its subsidiaries.
 
 Shareholder Suits
 
  1. Fry, et al. v. UAL Corp.--On February 21, 1990, a class action complaint
was filed in the U.S. District Court for the Northern District of Illinois,
Eastern Division, by several UAL shareholders, on behalf of the
 
                                       16
<PAGE>
 
class of UAL shareholders who sold puts or common stock from October 29, 1987
through December 8, 1987. The complaint alleges that UAL committed common law
fraud and violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated
thereunder and the Illinois Deceptive Trade Practices Act by falsely announcing
that it intended to distribute proceeds of the 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 seek unspecified damages, plus fees and other
costs. The issues have been joined, and discovery is proceeding.
 
  2. In Re UAL Shareholder Litigation.--In August and September 1989, four
purported class action complaints by UAL shareholders against UAL and its Board
of Directors in the Circuit Court of Cook County were consolidated. The
complaints allege that (1) UAL directors breached their fiduciary duties to the
shareholders in connection with the Board's dealings with Marvin Davis, an
investor allegedly interested in acquiring UAL, as part of a larger scheme of
entrenchment by the Board of Directors; (2) fees paid by UAL in connection with
a 1989 attempt by Airline Acquisition Corp. to acquire UAL should be reimbursed
to UAL; and (3) the Board's acceptance of a 1990 offer by United Employee
Acquisition Corp. to acquire UAL was improper because the offer was unfairly
low. The parties have agreed on a proposed settlement which is subject to court
approval, and a decision from the court is expected in the near term.
 
  3. Krasner v. UAL Corp. et al.--On August 7, 1989, a purported class action
complaint was filed in Delaware Chancery Court against UAL and certain
directors and officers. The complaint, as amended, alleges: (i) the individual
defendants engaged in a plan and scheme to entrench themselves at the expense
of the public shareholders of UAL; (ii) the individual defendants breached
their fiduciary duties owed to UAL's shareholders; (iii) the individual
defendants failed to shop UAL and cause its sale to a third party; (iv) the
individual defendants wasted UAL assets by paying or committing to pay fees and
expenses of two potential acquirors of UAL; (v) that UAL should not have
proposed a major purchase of aircraft; (vi) and that UAL should not have given
United Employees Acquisition Corp. ("UEAC") an extension of the deadline for
securing financing for the UEAC buyout without receiving some consideration.
This case would be settled as part of the settlement of In Re UAL Shareholder
Litigation, above.
 
  4. Stepak v. UAL Corp.--On August 8, 1989, a purported class action complaint
was filed by an alleged shareholder against UAL and each member of the Board in
the Delaware Chancery Court. The complaint alleges that the Board breached its
fiduciary duties to the shareholders by amending UAL's Shareholder Rights
Agreement on July 27, 1989 in a manner unreasonable in light of the interest
expressed by Marvin Davis in acquiring UAL. The complaint seeks declaratory
relief, unspecified damages, costs and disbursements, including counsel fees.
This case would be settled as part of the settlement of In Re UAL Shareholder
Litigation, above.
 
  5. Berger v. UAL Corp.--On August 8, 1989, a purported class action complaint
was filed by an alleged shareholder against UAL and each member of the Board in
the Delaware Chancery Court. The complaint alleges that the Directors breached
their fiduciary duties to the shareholders by taking actions which preclude any
third party bid for UAL, including allegedly failing to negotiate with Mr.
Davis or other prospective purchasers. The complaint seeks an order requiring
the Board to carry out its fiduciary duties by announcing their intention to
(1) cooperate fully with Marvin Davis or any other person or entity having a
bona fide interest in proposing any transaction which would maximize
shareholder value; (2) undertake an appropriate evaluation of UAL's value as a
merger/acquisition candidate; (3) take all appropriate steps to enhance UAL's
value as a merger/acquisition candidate; (4) take all appropriate steps to
expose UAL to the market in an effort to create value for the shareholders; (5)
"act independently" to protect the interests of UAL's shareholders; and (6)
ensure that no conflict of interest existed between the directors and the
shareholders of UAL. The complaint seeks to void or redeem the Rights Plan, and
to enjoin UAL and the Board from taking any action which would deprive the
shareholders of the opportunity to freely consider and accept any offer to
purchase UAL. The complaint also seeks unspecified damages and costs and
disbursements, including attorneys' and experts' fees. This case would be
settled in March 1994 as part of the settlement of In Re UAL Shareholder
Litigation, above.

<PAGE>
 
  6. Berger and Lewis v. UAL Corporation, et al.--A purported class action
complaint filed in the Delaware Chancery Court on May 23, 1990 on behalf of all
UAL shareholders who owned stock on October 13, 1989. The complaint alleges
that executive officer and director defendants willfully and knowingly
participated in and/or aided and abetted a plan and scheme to protect their
positions of management and control of the company and/or financial benefits
and perquisites derived from their positions while the pilots, machinists and
flight attendants, represented by their respective unions, utilized their
collective position of employment to gain control and ownership of the Company.
The complaint demands that three new independent directors be appointed "to
represent the shareholders only"; an independent financial advisor be retained
to represent the "shareholders only"; seeks to enjoin the new deal pending the
appointment of such directors and seeks unspecified damages for recklessly
accepting the $300 bid and having failed to accept Davis' $275 proposal. This
case would be settled in March 1994 as part of the settlement of In Re UAL
Shareholder Litigation, above.
 
  7. Kaufman v. UAL Corporation and Krasner, et al. v. UAL--These actions were
filed in early 1994 in the Delaware Court of Chancery challenging the employee
investment transaction recently agreed to among UAL, ALPA and IAM. The
complaints, which purport to be brought on behalf of all similarly situated
shareholders, name as defendants UAL and some or all of the current and former
directors of UAL and allege that the proposed Employee Investment Transaction
fails to deliver sufficient value to shareholders. In Kaufman, UAL and the
other defendants have been served; in Krasner, however, no service has been
effected.
 
 Noise Proceedings
 
  United may be affected by legal proceedings brought by owners of property
located near certain airports. Plaintiffs generally seek to enjoin certain
aircraft operations and/or to obtain damages against airport operators and air
carriers as a result of alleged aircraft noise or air pollution. Any liability
or injunctive relief imposed against airport operations or air carriers could
result in higher costs to United and other air carriers.
 
  The ultimate disposition of the matters discussed in Item 3 hereof, and other
claims affecting the Company, are not expected to have a material adverse
effect on the Company's financial condition.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  No matter was submitted to a vote of security holders of the Company during
the fourth quarter of 1993.
 
EXECUTIVE OFFICERS OF THE REGISTRANT

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On December 22, 1993, the Board of Directors of UAL Corporation ("UAL")
approved a non-binding agreement in principle that would provide a majority
equity interest in the corporation to the employees of
 
                                       19
<PAGE>
 
United Air Lines, Inc. ("United") in exchange for wage concessions and work-
rule changes. In January 1994, the agreement was ratified by the Air Line
Pilots Association ("ALPA") and the International Association of Machinists
("IAM"). The transaction is subject to, among other things, approval by UAL
stockholders.
 
  The employee investment plan is intended to put in place a lower cost
structure that allows United to compete effectively in the aviation marketplace
and address its long-term financial viability. The concessions will come from
three of United's employee groups: employees represented by ALPA, employees
represented by the IAM and the salaried and management employees. Employees
represented by the Association of Flight Attendants ("AFA") have been invited
to participate in the plan and UAL has engaged in discussions with the AFA
concerning such participation.
 
  In the transaction, an Employee Stock Ownership Plan will be created to
provide United employees with a minimum of a 53% equity interest in UAL in
exchange for wage concessions and work-rule changes. The employee interest may
increase to up to 63%, depending on the average market value of UAL common
stock in the year after the transaction closes. The transaction is not
dependent on external financing.
 
  Pursuant to the terms of the agreement in principle, current UAL stockholders
would receive the remaining 37 to 47% of the common stock and $88 per share in
cash and face amount of debt and preferred stock. The non-common stock
consideration is expected to aggregate approximately $743 million of cash, $900
million face amount of senior unsecured debentures and $900 million face amount
of preferred stock depending on the number of common shares on which the
distribution is made.
 
  The agreement includes terms for the creation of a low-cost short-haul
operation to compete in domestic markets. This short-haul operation, in
combination with the other wage and work-rule concessions, is expected to
increase UAL's cash flows from operating activities.
 
  UAL agreed that if the transaction closes prior to August 31, 1994, severance
payments and employee benefits coverage approximating $50 million would be
provided to IAM employees being terminated from United as a result of the
recent sale of flight kitchens (see Sale of Flight Kitchens), in addition to
payments required under United's labor contracts. Certain of the severance
payments, which are to be made on a monthly basis, became payable in January
1994 after the unions ratified the agreement; however, these monthly payments
terminate but are not refunded if the transaction does not close before August
31, 1994 or certain other conditions are not met. Other lump-sum severance
amounts are only payable if the transaction closes prior to the required date.
UAL has also agreed to pay up to $45 million of transaction fees and expenses
incurred by ALPA and the IAM if the transaction is closed by August 31, 1994.
If the transaction does not close by the required date but certain conditions
are met, UAL will pay up to $12.5 million of ALPA and IAM transaction expenses.
In addition, under the terms of UAL's outstanding incentive compensation
arrangements, if the transaction closes, additional stock options will become
exercisable and unvested restricted shares will vest.
 
  Under the terms of the agreement in principle, UAL has agreed not to issue or
redeem equity securities, incur incremental debt or other obligations, or sell
certain assets, other than in the ordinary course of business, prior to the
consummation of the transaction. In addition, after consummation of the
transaction, certain activities, including the issuance of equity or equity
equivalent securities and certain asset dispositions, may require a different
approval process by the UAL Board of Directors, and in some cases the
shareholders, than is currently required.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During 1993, UAL's total cash, cash equivalents and short-term investments
increased $345 million to a balance of $1.828 billion at December 31, 1993.
Operating activities generated $858 million and the issuance of convertible
preferred stock provided $591 million. Cash was used primarily to repay long-
term debt, reduce short-term borrowings and to fund net additions to property
and equipment.
 
 
                                       20
<PAGE>
 
  The issuance of six million shares of 6.25% cumulative convertible preferred
stock in February 1993 resulted in net proceeds of $591 million. Repayments of
long-term debt amounted to $695 million, including the early extinguishment of
$500 million of senior subordinated notes in June 1993. In addition, $55
million was used for capital lease payments during the period. Long-term debt
and capital lease obligations incurred in connection with aircraft financings
during 1993 amounted to $557 million. As a result of the year's financing
activities, UAL's debt:equity ratio improved from 86:14 at December 31, 1992 to
77:23 at December 31, 1993.
 
  During 1993, United placed 43 new aircraft in service. These aircraft were
financed primarily with long-term debt, capital leases and operating leases.
United acquired 10 B737-500 aircraft, 16 B757-200 aircraft, four B747-400
aircraft, eight B767-300ER aircraft and five A320-200 aircraft during 1993. Of
these, 16 aircraft were purchased, 18 were purchased and then sold and leased
back, seven were acquired under operating leases and two were acquired in
capital lease transactions. Aircraft purchases and other property additions,
including aircraft modification projects and aircraft spare parts, amounted to
$1.496 billion. Property dispositions, which included sale and leaseback
transactions and the sales of five B727 aircraft, provided $1.165 billion.
 
  In early 1993, United revised its capital spending plan based on reductions
in its capacity requirements for the next several years. United reached
agreement with The Boeing Company ("Boeing") to convert certain aircraft orders
into options. Under the terms of the agreement, if United does not elect to
confirm the delivery of these option aircraft before 1998, it will forfeit
significant deposits. United also announced an agreement with Airbus Industrie
("Airbus") to delay from 1995 and 1996 to 1997 and 1998 delivery of 14 leased
A320 aircraft. In addition, United announced that it would accelerate the
retirement of 25 widebody aircraft, including 15 DC10-10s and ten B747-SPs,
retiring them prior to the end of 1994. In 1993, United recorded a $59 million
charge to reduce the net book value of the DC-10 aircraft to estimated net
realizable value.
 
  As a result of these new agreements, as of December 31, 1993, United had
taken delivery of all aircraft on order, with the exception of 34 B777
aircraft, which are expected to be delivered between 1995 and 1999. In addition
to the B777 order, United has arrangements with Airbus and International Aero
Engines to lease an additional 45 A320 aircraft, which are scheduled for
delivery through 1998. At December 31, 1993, United also had options for 186
B737 aircraft, 54 B757 aircraft, 34 B777 aircraft, 52 B747 aircraft, eight B767
aircraft and 50 A320 aircraft. In January 1994, United entered into an
agreement with Boeing to acquire two B747-400 aircraft in 1994 in place of
options for two similar aircraft. United continually reviews its fleet to
determine whether aircraft acquisitions will be used to expand the fleet or to
replace older aircraft, depending on market and regulatory conditions at the
time of delivery.
 
  Commitments for the purchase of aircraft and other property at December 31,
1993 approximated $4.3 billion, after deducting advance payments. An estimated
$0.6 billion will be spent in 1994, $1.1 billion in 1995, $0.8 billion in 1996,
$1.2 billion in 1997, $0.4 billion in 1998, and $0.2 billion after 1998. These
amounts do not include the two B747-400 aircraft to be acquired under the
January 1994 agreement referred to above.
 
  Funds necessary to finance aircraft acquisitions are expected to be obtained
from internally generated funds, irrevocable external financing arrangements or
other external sources. In 1993, UAL and United filed a shelf registration
statement with the Securities and Exchange Commission for up to $1.5 billion of
securities, including secured and unsecured debt, equipment trust certificates,
equity or a combination of both. Under the terms of this shelf registration
statement, a 1992 shelf and a 1991 shelf were combined with the 1993 shelf
statement. In December 1993, United issued $100.0 million of debentures under
the shelf registration statement. In May and November 1993, United issued $176
million and $118 million, respectively, of pass through certificates under the
shelf registration to refinance aircraft under operating leases. On a combined
basis, up to $1.776 billion of additional securities may be offered at December
31, 1993. The shelf registration statement may be utilized for purposes of
registering securities to be issued in the employee investment transaction.
 
 
                                       21
<PAGE>
 
  United's senior unsecured debt is rated BB by Standard & Poor's Corporation
("S & P") and Baa3 by Moody's Investors Service Inc. ("Moody's"). UAL's
convertible preferred stock is rated B+ by S & P and ba3 by Moody's. These
ratings reflect an October 1993 downgrade by Moody's. On December 17, 1993,
Moody's announced that it was placing United's and UAL's securities under
review for possible downgrade citing reports about the potential for the
employee investment transaction. On December 20, 1993, S & P announced that it
was placing the securities on CreditWatch with developing implications, meaning
the ratings may be raised or lowered.
 
  United is in the process of constructing a maintenance facility in
Indianapolis, which begins operation in 1994. The facility is being financed
primarily with tax-exempt bonds and other capital sources.
 
  As of December 31, 1993, UAL had a working capital deficit of $1.183 billion.
Historically, UAL has operated with a working capital deficit and, as in the
past, UAL expects to meet all of its obligations as they become due.
 
  Operating activities in 1992 generated cash flows of $575 million, which more
than offset cash used for net additions to property, resulting in a $306
million increase in cash, cash equivalents and short-term investments. During
the year, $2.519 billion was spent on property additions, principally aircraft.
United acquired 25 B737-500 aircraft, 25 B757-200 aircraft, 10 B767-300ER
aircraft and six B747-400 aircraft in 1992. Of these, 18 aircraft were
purchased, 38 were purchased and then sold and leased back and 10 were acquired
in capital lease transactions. Property dispositions provided cash proceeds of
$2.367 billion. In 1992, United also acquired certain Latin American route
authorities and other related assets from Pan American World Airways, Inc.
("Pan Am").
 
  During 1991, operating property additions amounted to $2.122 billion and
included the acquisition of 23 B757-200 aircraft, 18 B737-500 aircraft, five
B767-300ER aircraft, four B747-400 aircraft and seven used B747-200 aircraft.
Dispositions of property, including the sale and leaseback of 15 aircraft and
the sales of two DC8-71 aircraft and four B727-100 aircraft, provided $1.281
billion. United also acquired international route authorities and other assets
from Pan Am, which was the primary cause of a $358 million increase in
intangibles. However, cash provided by operating activities of $338 million and
financing activities of $841 million allowed UAL to maintain a relatively
stable balance of cash, cash equivalents and short-term investments, which
amounted to $1.176 billion at December 31, 1991.
 
RESULTS OF OPERATIONS
 
  UAL's results of operations in 1993 improved considerably as compared to
1992. In 1993, UAL recorded a net loss of $50 million, $3.40 per share,
compared to a 1992 net loss of $957 million, $39.75 per share. The 1993 results
include an extraordinary loss of $19 million on the early extinguishment of
debt. The 1992 results include a $540 million cumulative effect of adopting
Statement of Financial Accounting Standard ("SFAS") No. 106, "Employers'
Accounting for Postretirement Benefits Other than Pensions" and SFAS No. 109,
"Accounting for Income Taxes." The 1993 loss before extraordinary item was $31
million, $2.64 per share, compared to a 1992 loss before cumulative effect of
accounting changes of $417 million, $17.34 per share.
 
  UAL recorded operating earnings in 1993 of $263 million compared to an
operating loss in 1992 of $538 million. The improved performance in 1993 was
benefitted by the cost reduction program implemented in 1993, the realignment
of domestic schedules to eliminate unprofitable routes in an effort to enhance
revenue performance and the impact of a labor union strike on a competing air
carrier. UAL's 1992 losses were significantly affected by uneconomic fare
actions initiated by other carriers that increased traffic and load factors to
unprecedented levels, but resulted in substantially reduced yield (passenger
revenue per revenue passenger mile).
 
  While UAL's results showed improvement in 1993, the results of operations in
the airline business can fluctuate significantly in response to general
economic conditions. This is because small fluctuations in yield
 
                                       22
<PAGE>
 
and cost per available seat mile can have a significant effect on operating
results. Thus, UAL believes that industrywide fare levels, increasing low-cost
competition, prolonged operations of carriers under bankruptcy protection,
general economic conditions, fuel costs, international governmental policies
and other factors over which it has limited control, will continue to affect
its operating results.
 
  In addition, United expects its 1994 operating results to be impacted by
increases in operating expenses of approximately $100 million related to
operations at the new Denver International Airport, and approximately $70
million related to employee pension costs as a result of lowering the assumed
discount rate from 8.75% to 7.5%.
 
 1993 Compared with 1992
 
  Operating Revenues. Operating revenues increased $1.621 billion (13%).
Passenger revenues increased $1.317 billion (11%) due to a 9% increase in
United's revenue passenger miles and a 2% increase in yield to 12.48 cents.
United's domestic revenue passenger miles increased 6% on an increase of 8% in
domestic available seat miles, resulting in a decrease of 1.0 point in domestic
passenger load factor to 65.2%. International revenue passenger miles increased
14%. Passenger traffic increased in substantially all international markets,
especially in Latin America, where United began service in the first quarter of
1992. Passenger load factors increased in Latin America, the Atlantic and the
Pacific. On a system basis, United's available seat miles increased 10% and
passenger load factor decreased 0.2 points to 67.2%.
 
  Cargo revenues increased $166 million (21%), due to increases of $143 million
in freight revenues and $23 million in mail revenues. The freight revenue
increase reflects both volume and unit revenue increases largely attributable
to increased international operations. Contract services and other revenues
increased $138 million (24%) primarily as a result of revenues generated by
Apollo Travel Services Partnership ("ATS"), a consolidated general partnership
77% owned by United, that was formed by the 1993 merger of two affiliates of
United. (see Note 3 of the Notes to Consolidated Financial Statements)
 
  Operating Expenses. Operating expenses increased $820 million (6%). United's
cost per available seat mile decreased 3% to 9.33 cents. The decrease in unit
cost was largely due to the implementation of a cost reduction program in early
1993. Commissions increased $285 million (13%) due to increased revenues and
slightly higher cargo commission rates. Salaries and related costs increased
$198 million (4%) primarily due to higher average wage rates and higher costs
associated with pensions and health insurance. Rentals and landing fees
increased $163 million (12%) primarily reflecting rent associated with a larger
number of aircraft on operating leases. Aircraft maintenance increased $55
million (17%) due principally to higher outside maintenance costs. Purchased
services increased $47 million (5%) due principally to higher computer
reservations fees and higher costs associated with international operations,
such as communications, navigation charges and security. Depreciation and
amortization increased $38 million (5%) due principally to newly acquired
aircraft. Aircraft fuel expense increased $34 million, as a 7% increase in fuel
consumption was partially offset by a 4% decrease in the average price per
gallon of fuel to 63.6 cents. Other operating expenses increased $85 million
(11%) due principally to the consolidation of ATS after the merger. Advertising
and promotion decreased $52 million (24%) and food and beverages decreased $25
million (7%) due to cost reduction efforts.
 
  Other Income and Expense. Other expense amounted to $310 million in 1993
compared to $118 million in 1992. Interest expense increased $30 million due
primarily to increased debt and capital lease obligations incurred in
connection with aircraft financings. Interest capitalized decreased $41 million
(45%) due to lower advance payments on new aircraft. United's equity in the
results of affiliates shifted from income of $42 million in 1992, representing
United's share of Covia Partnership ("Covia") earnings, to losses of $30
million in 1993, primarily due to a charge recorded by Galileo International
for the cost of eliminating duplicate facilities and operations after the
merger of Covia and the Galileo Company. Included in "Miscellaneous, net" were
foreign exchange losses of $20 million in 1993 compared to gains of $2 million
in 1992. Also included in 1993 was a charge of $59 million to reduce the net
book value of 15 DC-10 aircraft to estimated
 
                                       23
<PAGE>
 
net realizable value and a $17 million gain resulting from the final settlement
for overpayment of annuities purchased in 1985 to cover certain vested pension
benefits. Interest income increased $29 million due principally to interest
received in connection with the same settlement. In 1992, "Miscellaneous, net"
also included gains on disposition of property of $32 million, a charge of $13
million to record the cash settlement of class action claims resulting from
litigation relating to the use of airline fare data and charges of $8 million
related to other litigation.
 
 1992 Compared with 1991
 
  In 1992, UAL recorded a net loss of $957 million, compared to the 1991 net
loss of $332 million. The 1992 loss before the cumulative effect of adoption of
SFAS No. 106 and SFAS No. 109 was $417 million.
 
  Operating Revenues. Operating revenues increased $1.227 billion (11%).
Passenger revenues increased $1.228 billion (12%) due to a 13% increase in
United's revenue passenger miles partially offset by a 2% decrease in yield to
12.19 cents. The increase in passenger traffic was largely attributable to
United's international operations. European operations increased significantly
with the April 1991 acquisition of route authorities from Pan Am. Latin
American operations began in January 1992 as United started serving certain
former Pan Am destinations. Pacific air travel demand also improved compared to
1991, which was adversely impacted by the Gulf war. Domestic traffic increased
primarily as a result of fare reductions initiated by other carriers. United's
domestic revenue passenger miles increased 5% and available seat miles
increased 2%, resulting in a 2.0 point increase in domestic load factor to
66.2%. On a system basis, United's revenue passenger miles increased 13% and
available seat miles increased 11%, resulting in a 1.1 point increase in
passenger load factor to 67.4%.
 
  Cargo revenues increased $92 million (13%), primarily due to increased
freight revenues, reflecting both volume and unit revenue increases as a result
of expanded international operations. Contract services and other revenues
decreased $93 million (14%) primarily as a result of a decrease in fuel sales.
 
  Operating Expenses. Operating expenses increased $1.271 billion (10%).
United's cost per available seat mile decreased 2% to 9.6 cents. Salaries and
related costs increased $505 million (12%) primarily due to increased flight
crew and customer service personnel, higher average wage rates and higher costs
associated with pensions and health insurance. The increase in salaries and
related costs included $75 million related to SFAS No. 106, which was adopted
effective January 1, 1992. Rentals and landing fees increased $257 million
(24%) reflecting rent associated with an increasing number of aircraft on
operating leases and higher airport facilities rent and landing fees, primarily
related to international operations. Commissions increased $185 million (9%)
due to increased revenues, as average commission rates remained relatively
unchanged. Purchased services increased $152 million (19%) due principally to
higher computer reservations fees and higher costs associated with
international operations, such as communications, navigation charges and
security. Depreciation and amortization increased $122 million (20%) due
principally to newly acquired aircraft. Food and beverages increased $50
million (17%) due to a higher per passenger cost, reflecting a passenger mix
more heavily weighted by international passengers. Aircraft fuel expense
increased $25 million, as an 8% increase United's in fuel consumption was
partially offset by a 7% decrease in the average price per gallon of fuel to
66.4 cents. Aircraft maintenance decreased $33 million (9%) due principally to
lower outside maintenance costs and the retirement of the B727-100 fleet. Other
operating expenses decreased $31 million due to selling less fuel to third
parties.
 
  Other Income and Expense. Other expense amounted to $118 million in 1992
compared to $14 million in 1991. Interest expense increased $118 million due
primarily to increased debt and capital lease obligations incurred in
connection with 1991 and 1992 aircraft financings. Interest income decreased
$16 million due to lower interest rates. Equity in the earnings of affiliates
increased $35 million as a result of higher Covia booking revenues and the
settlement of certain partner accounts in 1991. "Other income (expense)--
Miscellaneous, net" included foreign exchange gains of $2 million in 1992
compared to losses of $20 million

in 1991. Also included in 1992 was a charge of $13 million to record the cash
settlement of class action claims resulting from litigation relating to the
use of airline fare data and gains of $32 million on the disposition
of property, primarily one B747-SP aircraft, seventeen B727 aircraft and four
B737-200 aircraft. In 1991, gains on the disposition of property amounted to
$49 million, which reflected sales of two DC8-71s and four B727-100s.
 
OTHER INFORMATION
 
 Deferred Tax Asset
 
  UAL's consolidated balance sheet at December 31, 1993 includes a net
cumulative deferred tax asset of $714 million. The net deferred tax asset is
composed of approximately $2.0 billion of deferred tax assets and
approximately $1.3 billion of deferred tax liabilities. The deferred tax
assets include, among other things, $599 million related to obligations for
postretirement and other employee benefits, $480 million related to gains on
sales and leasebacks, $195 million related to alternative minimum tax ("AMT")
credit carryforwards and $42 million of Air Wisconsin, Inc. federal net
operating loss ("NOL") carryforwards. The AMT credit carryforwards do not
expire; the federal NOL carryforwards begin to expire in 2007 if not utilized
prior to that time.
 
  The majority of the deferred tax assets will be realized through reversals
of existing deferred tax liabilities with similar reversal patterns. To
realize the benefits of the remaining deferred tax assets relating to
temporary differences, UAL needs to generate approximately $1.3 billion in
future taxable income. Based on the expectations for future taxable income,
the extended period over which postretirement benefits will be recognized, and
the indefinite carryforward period for AMT credits, management believes it is
more likely than not that the deferred tax assets will be realized.
 
  Although United has experienced both book and tax losses in the past three
years, in the ten years prior to these losses, UAL reported cumulative taxable
income of $3.8 billion (including $1.8 billion of gains on dispositions of
businesses). Following is a summary of UAL's pretax book income and taxable
income for the last five years:

Taxable income (loss)........................... $(219) $(551) $(785) $280 $496
</TABLE>
 
  The losses in the past three years were largely attributable to certain
events beyond management control, including the Gulf war, the unanticipated
duration of the recession in both the U. S. and other areas of the world and
the proliferation of numerous low-cost air carriers resulting in severe
competition in the airline industry. While the economic outlook in Japan and
Europe could continue to negatively affect United's operating results,
management believes that these economies will begin to improve, and when
combined with certain cost containment strategies, UAL's financial results
should improve.
 
  Management has already taken several steps to reduce costs and capital
expenditures. UAL's improved operating results in 1993 versus 1992 are
principally attributable to these actions, as highlighted below:
 
  .  Implemented a program in January 1993 to reduce planned 1993 operating
     expenses by $400 million, including the furlough of 2,800 employees in
     February 1993.
 
  .  Reached agreement with Boeing, its principal supplier, to convert 49
     aircraft orders into options and defer their scheduled delivery dates.
 
  .  Reduced 1993 to 1996 capital spending by $6 billion.
 
  .  Agreed to sell flight kitchens which will result in the avoidance of an
     estimated $70 million of capital expenditures and estimated cost savings
     of more than $320 million over the seven year catering
 
                                      25
<PAGE>
 
    contract with the purchaser, before taking into account the severance
    payments resulting from the employee investment transaction.
 
  . Accelerated the retirement of 25 older aircraft to reduce costs and
    improve operating efficiencies.
 
  . Negotiated over $100 million in annual savings from suppliers.
 
  . Reduced domestic capacity by eliminating certain unprofitable routes and
    reducing capacity in certain markets to better match demand.
 
  . Increased the use of cooperative arrangements with domestic and
    international carriers resulting in increased revenue opportunities
    through code-sharing.
 
  The long-term financial stability and profitability of the company is
expected to be further enhanced through the proposed employee investment
transaction. However, in the event the proposed employee investment transaction
does not occur, UAL is prepared to make additional structural changes to return
to profitablilty.
 
  UAL's ability to generate sufficient amounts of taxable income from future
operations is dependent upon numerous factors, including general economic
conditions, inflation, oil prices, the state of the industry and other factors
beyond management's control. In the event that future taxable income is
inadequate to realize the benefits of the remaining deferred tax assets, UAL
has identified certain tax planning strategies that would significantly
contribute to the utilization of these assets. These strategies include, among
other things, eliminating the prefunding of certain employee benefits and the
sale of unused route authorities.
 
  There can be no assurances that UAL will meet its expectation of future
taxable income. However, based on the above factors, management believes it is
more likely than not that future taxable income will be sufficient to utilize
the cumulative deferred tax assets at December 31, 1993.
 
CONTINGENCIES
 
  During 1992, United recorded a $13 million charge representing its share of
the cash component of a settlement of certain class action claims. Under the
settlement, which has been approved by the U.S. District Court, six airlines
paid approximately $45 million in cash and will issue $397 million in face
amount of certificates affording discounts of up to approximately 10% on future
air travel on any of the six carriers.
 
  No liability was established for the certificate portion of the settlement
since United expects that in the aggregate, future revenues associated with
certificate redemption will exceed the cost of providing the related air
service. United anticipates that the portion of the total issued certificates
that may be redeemed on United will approximate United's 22% market share among
the six carriers, but actual redemption may be greater or lesser.
 
  The ultimate impact of the settlement on United's future revenues, operating
margins and earnings is not reasonably estimable since neither the portion of
the certificates to be redeemed on United nor the generative or dilutive
revenue effect of certificate redemption is known.
 
  United has been named as a Potentially Responsible Party at certain
Environmental Protection Agency ("EPA") cleanup sites which have been
designated as Superfund Sites. At sites where the EPA has commenced remedial
litigation, potential liability is joint and several. United's alleged
proportionate contributions at the sites are minimal. Additionally, United has
participated and is participating in remediation actions at certain other
sites, primarily airports. The estimated cost of these actions is accrued when
it is determined that it is probable that United is liable. Such accruals have
not been material.
 
  UAL has certain other contingencies resulting from litigation and claims
incident to the ordinary course of business. Although the ultimate outcome of
these matters could have a material effect on UAL's financial condition,
operating results or liquidity, management believes, after considering a number
of factors,
 
                                       26
<PAGE>
 
including (but not limited to) the views of legal counsel, the nature of such
contingencies and prior experience, that the ultimate disposition of these
contingencies is not likely to materially affect UAL's financial condition,
operating results or liquidity.
 
NEW ACCOUNTING STANDARDS
 
  In November 1992, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 112, "Employers' Accounting for Postemployment Benefits," which
requires recognition of the liability for postemployment benefits during the
period of employment. Such benefits include company paid continuation of group
life insurance and medical and dental coverage for certain employees after
employment but before retirement. UAL will adopt the new standard in the first
quarter of 1994. Based on preliminary estimates, UAL currently expects to
record a transition obligation, which will result in a cumulative charge of
$26 million, net of tax. Prior years' financial statements will not be
restated. Ongoing expenses will vary based on actual claims experience.
 
  In May 1993, the FASB issued SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," which requires fair value
accounting for certain investments. UAL is required to adopt the new standard
in 1994 and the standard is not to be applied retroactively. Upon adoption, UAL
will record a periodic charge or credit to adjust the carrying value of certain
investments to fair value. The adjustment will be recorded in earnings or as a
separate component of equity, depending on the type of investment. UAL does not
expect a material impact on either earnings or equity as a result of adopting
SFAS No. 115.
 
ENERGY TAX
 
  The Omnibus Budget Reconciliation Act of 1993 signed into law on August 10,
1993, imposes a 4.3 cent per gallon tax on commercial aviation jet fuel
purchased for use in domestic operations. This new fuel tax will become
effective October 1, 1995, and is scheduled to continue until October 1, 1998.
Based on United's 1993 domestic fuel consumption of 1.7 billion gallons, the
new fuel tax, when effective, is expected to increase United's operating
expenses by approximately $75 million annually.
 
FOREIGN CURRENCY TRANSACTIONS
 
  United generates revenues and incurs expenses in numerous foreign currencies;
however, United has limited exposure to foreign exchange rate fluctuations due
to its ability to convert excess local currencies generated to U.S. dollars. In
addition, United has exposure to transaction gains and losses resulting from
rate fluctuation. The foreign exchange gains and losses recorded in recent
years, including losses recorded in early 1993, were primarily the result of
the impact of exchange rate changes on unhedged Japanese yen- denominated long-
term debt, lease obligations and current liabilities, since the aggregate
balance of such liabilities exceeded United's yen-denominated assets. During
1993, United increased the amount of its yen-denominated assets to minimize the
impact of foreign exchange rate changes on reported financial results.
 
SALE OF FLIGHT KITCHENS
 
  In the third quarter of 1993, United reached agreements to sell assets
related to the operation of 16 of its flight kitchens to Dobbs International
Services, Inc. and Caterair International Corp. for $119 million. Under the
agreements, the purchasers will provide catering services for United at the
airports served by the flight kitchens for seven years. United expects the
catering agreement to result in savings of approximately $320 million over its
term, before taking into account the severance payments resulting from the
employee investment transaction. The asset sales for most, if not all, of the
flight kitchens are expected to be completed in the second quarter of 1994. The
asset sales result in an insignificant gain.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders and Board of
 Directors, UAL Corporation:
 
  We have audited the accompanying statement of consolidated financial position
of UAL Corporation (a Delaware corporation) and subsidiary companies as of
December 31, 1993 and 1992, and the related statements of consolidated
operations, consolidated cash flows and consolidated shareholders' equity for
each of the three years in the period ended December 31, 1993. These financial
statements and the schedules referred to below are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of UAL
Corporation and subsidiary companies as of December 31, 1993 and 1992, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1993, in conformity with generally accepted
accounting principles.
 
  As discussed in notes 6 and 15 to the consolidated financial statements,
effective January 1, 1992, the Company changed its methods of accounting for
income taxes and postretirement benefits other than pensions.
 
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedules referenced in Item
14(a)(2) herein are presented for purposes of complying with the Securities and
Exchange Commission's rules and are not part of the basic financial statements.
These schedules have been subjected to the auditing procedures applied in the
audit of the basic financial statements and, in our opinion, fairly state in
all material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 (a) Consolidation--
 
  UAL Corporation ("UAL") is a holding company whose principal subsidiary is
United Air Lines, Inc. ("United"). The consolidated financial statements
include the accounts of UAL and all of its subsidiaries. All significant
intercompany transactions are eliminated. Investments in affiliates are carried
on the equity basis.
 
 (b) Accounting Changes--
 
  Effective January 1, 1992, UAL adopted Statement of Financial Accounting
Standards ("SFAS") No. 106, "Employers' Accounting for Postretirement Benefits
Other Than Pensions" (see Note 15) and SFAS No. 109, "Accounting for Income
Taxes" (see Note 6).
 
 (c) Airline Revenues--
 
  Passenger fares and cargo revenues are recorded as operating revenues when
the transportation is furnished. The value of unused passenger tickets is
included in current liabilities.
 
 (d) Foreign Currency Transactions--
 
  Monetary assets and liabilities denominated in foreign currencies are
converted at exchange rates in effect at the balance sheet date. The resulting
foreign exchange gains and losses, and gains and losses on foreign currency
call options used to hedge foreign currency obligations, are charged or
credited directly to income.
 
 (e) Cash and Cash Equivalents and Short-term Investments--
 
  Cash in excess of operating requirements is invested in short-term, highly
liquid, income-producing investments. Investments with an original maturity of
three months or less on their acquisition date are classified as cash and cash
equivalents. Cash and cash equivalents and short-term investments are stated at
cost, which approximates market value. Due to the short maturity of these
instruments, their carrying amount is a reasonable estimate of fair value.
 
 (f) Aircraft Fuel, Spare Parts and Supplies--
 
  Aircraft fuel and maintenance and operating supplies are stated at average
cost. Flight equipment spare parts are stated at average cost less an
obsolescence allowance.
 
 (g) Operating Property and Equipment--
 
  Owned operating property and equipment is stated at cost. Property under
capital leases, and the related obligation for future minimum lease payments,
are initially recorded at an amount equal to the then present value of those
lease payments.
 
  Depreciation and amortization of owned depreciable assets is based on the
straight-line method over their estimated service lives. Leasehold improvements
are amortized over the remaining period of the lease or the estimated service
life of the related asset, whichever is less. Aircraft are depreciated to
estimated salvage values, generally over lives of 10 to 25 years; buildings are
depreciated over lives of 25 to 45 years; and other property and equipment are
depreciated over lives of three to 15 years.
 
  Properties under capital leases are amortized on the straight-line method
over the life of the lease, or in the case of certain aircraft, over their
estimated service lives. Lease terms are 10 to 19 years for aircraft and
 
                                       36

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

flight simulators and 25 years to 40 years for buildings. Amortization of
capital leases is included in depreciation and amortization expense.
 
  Gains or losses on dispositions of individual units of owned property and
equipment are reflected in earnings. Maintenance and repairs, including the
cost of minor replacements, are charged to maintenance expense accounts. Costs
of additions to and renewals of units of property are charged to property and
equipment accounts.
 
 (h) Intangibles--
 
  Intangibles consist primarily of route acquisition costs, slots and
intangible pension assets (see Note 14). Route acquisition costs and slots are
amortized over 40 years and 5 years, respectively.
 
 (i) Mileage Plus Awards--
 
  United accrues the estimated incremental cost of providing free travel awards
earned under its Mileage Plus frequent flyer program when such award levels are
reached.
 
 (j) Deferred Gains--
 
  Gains on aircraft sale and leaseback transactions are deferred and amortized
over the lives of the leases as a reduction of rental expense.
 
 (k) Interest Rate Swap Agreements--
 
  United enters into interest rate swap agreements to hedge certain interest
rate exposure. The differential to be paid or received under the swap
agreements is accrued and included in interest expense or rental expense.
 
(2) PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On December 22, 1993, the Board of Directors of UAL approved a non-binding
agreement in principle that would provide a majority equity interest in the
corporation to the employees of United in exchange for wage concessions and
work-rule changes. In January 1994, the agreement was ratified by the Air Line
Pilots Association ("ALPA") and the International Association of Machinists
("IAM"). The transaction is subject to, among other things, approval by UAL
stockholders.
 
  In the transaction, an Employee Stock Ownership Plan will be created to
provide United employees with a minimum of a 53% equity interest in UAL in
exchange for wage concessions and work-rule changes. The employee interest may
increase to up to 63%, depending on the average market value of UAL common
stock in the year after the transaction closes. The transaction is not
dependent on external financing.
 
  Pursuant to the terms of the agreement in principle, current UAL stockholders
would receive the remaining 37 to 47% of the common stock and $88 per share in
cash and face amount of debt and preferred stock. The non-common stock
consideration is expected to aggregate approximately $743 million of cash, $900
million face amount of senior unsecured debentures and $900 million face amount
of preferred stock depending on the number of common shares on which the
distribution is made.
 
  UAL agreed that if the transaction closes prior to August 31, 1994, severance
payments and employee benefits coverage approximating $50 million would be
provided to IAM employees being terminated from

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

United as a result of the recent sale of flight kitchens (see Note 19) in
addition to payments required under United's labor contracts. Certain of the
severance payments, which are to be made on a monthly basis, became payable in
January 1994 after the unions ratified the agreement; however, these monthly
payments terminate but are not refunded if the transaction does not close
before August 31, 1994 or certain other conditions are not met. Other lump-sum
severance amounts are payable only if the transaction closes prior to the
required date. UAL has also agreed to pay up to $45 million of transaction fees
and expenses incurred by ALPA and the IAM if the transaction is closed by
August 31, 1994. If the transaction does not close by the required date but
certain conditions are met, UAL will pay up to $12.5 million of ALPA and IAM
transaction expenses.
 
(3) MERGER OF AFFILIATES
 
  In September 1993, the Covia Partnership ("Covia"), a 50% owned affiliate of
United, and The Galileo Company Limited, a 25.9% owned affiliate of United,
merged. The merger resulted in the formation of the Apollo Travel Services
Partnership ("ATS") and the Galileo International Partnership ("Galileo"), two
general partnerships that are owned 77% and 38%, respectively, by United
through a wholly-owned subsidiary. Galileo owns the Apollo and Galileo computer
reservations systems. ATS is responsible for marketing, sales and support of
Apollo in the United States, Mexico and the Caribbean.
 
  Prior to the merger, United's investments in these companies were carried on
the equity basis. As a result of the merger and United's majority ownership of
ATS, the accounts of ATS are consolidated resulting in non-cash increases of
$78 million in assets, $46 million in liabilities and $34 million in minority
interests as of the date of the merger. United's investment in Galileo is
carried on the equity basis. The accounting for the merger resulted in no
change in the book value of the assets and liabilities of the companies
combined. During the fourth quarter, Galileo recorded a charge for the cost of
eliminating duplicate facilities and operations. United's share of this charge
was recorded in "Equity in earnings (loss) of affiliates." The merger is
expected to create operating efficiencies by eliminating duplication.
 
  Under operating agreements with Covia prior to the merger, United provided
certain computer support services for, and purchased computer reservation
services, communications and other information from Covia. Revenues derived
from the sale of services to Covia amounted to approximately $21 million, $22
million and $31 million in 1993, 1992 and 1991, respectively. The cost to
United of services purchased from the Covia Partnership amounted to
approximately $168 million, $219 million, and $191 million in 1993, 1992 and
1991, respectively. Under operating agreements with Galileo subsequent to the
merger, United purchases computer reservation services from Galileo and ATS
provides marketing, sales and communication services for Galileo. Revenues
derived from the sale of services to Galileo amounted to approximately $58
million and the cost of services purchased from Galileo amounted to
approximately $47 million in 1993.
 
  Summarized financial information for the significant entities accounted for
on the equity basis, follows.

(5) NET LOSS PER SHARE
 
  Net loss per share amounts are based on weighted average common shares
outstanding--24,345,857 in 1993, 24,069,786 in 1992, and 23,201,605 in 1991.
Per share amounts were calculated after providing for preferred stock dividends
of $33,229,000 in 1993, $42,000 in 1992 and $91,000 in 1991.
 
(6) INCOME TAXES
 
  In 1993, UAL incurred a regular tax loss but had an alternative minimum tax
("AMT") liability. The regular tax loss will be carried back to reduce taxable
income generated in previous years resulting in federal and state refunds and
additional AMT credits. Certain preferences, mainly depreciation adjustments,
have caused alternative minimum taxable income to exceed regular taxable
income, resulting in the AMT liability.
 
  The provision (credit) for income taxes is summarized as follows:

  UAL adopted SFAS No. 109 "Accounting for Income Taxes," effective January 1,
1992. This statement provides for an asset and liability approach to accounting
for income taxes. UAL recognized a tax benefit of $40 million for the
cumulative effect of adopting SFAS No. 109. Deferred income taxes (credit) for
1993 and 1992 reflect the impact of "temporary differences" between amounts of
assets and liabilities for financial reporting purposes and such amounts as
measured by tax laws. These temporary differences are determined in accordance
with SFAS No. 109 and are more inclusive in nature than "timing differences" as
determined under previously applicable accounting principles.
 
  During 1991, deferred income taxes were provided for significant timing
differences in the recognition of revenue and expenses for tax and financial
statement purposes. Principally, these items consisted of the following: $81
million for depreciation and capitalized interest, $(62) million for gains on
sale and leaseback transactions, $32 million for gains on asset dispositions,
$(24) million for rent expense, $(31) for pension expense, $16 million for
other employee benefits and $12 million for prepaid commissions.
 
  Temporary differences and carryforwards which give rise to a significant
portion of deferred tax assets and liabilities for 1993 and 1992 are as
follows:

  UAL has determined, based on its history of operating earnings, available
carrybacks, expectations for the future and potential tax planning strategies,
that it is more likely than not that the deferred tax assets at December 31,
1993 will be realized before expiration.

  At December 31, 1993, UAL and its subsidiaries had $195 million of federal
AMT credit carryforwards available for an indefinite period, $4 million of
general business credit carryforwards which expire between 2007 and 2009, $32
million of state tax benefit from net operating loss carryforwards expiring
between 1997 and 2009 and $42 million of federal tax benefit from net operating
loss carryforwards expiring between 2007 and 2009.
 
(7) SHORT-TERM BORROWINGS
 
  At December 31, 1993, United had outstanding $315 million in short-term
borrowings, bearing an average interest rate of 3.34%. Receivables amounting to
$367 million were pledged by United to secure repayment of such outstanding
borrowings. Due to the short maturity of these borrowings, their carrying
amount is a reasonable estimate of fair value. In February 1993, United entered
agreements to increase the maximum available amount of borrowings under this
arrangement from $450 million to $500 million. Pursuant to the terms of this
agreement, in the event of a change in control of United or UAL, such as the
proposed employee investment transaction, the lenders under this agreement may
decline to make new loans to United.

  The fair value of long-term debt, including current maturities, at December
31, 1993 and 1992 were estimated to be $3.041 billion and $3.044 billion,
respectively, based on the quoted market prices for the same or similar issues
or on the then current rates offered for debt of the same remaining maturities.
 
  In the second quarter of 1993, United retired $500 million of senior
subordinated notes. The notes, bearing interest at 12.5% and 13%, were
scheduled to mature in 1995 and 1998 for $150 and $350 million, respectively.
An extraordinary loss of $19 million, net of tax benefits of $8 million, was
recorded in the first quarter of 1993, based on United's stated intention to
retire the notes.
 
  In May 1993, United issued $176 million of pass through certificates under a
1992 shelf registration to refinance aircraft under operating leases. In June
1993, a new shelf registration filed by UAL and United for up to $1.5 billion
of securities, including secured and unsecured debt, equipment trust and pass
through certificates, equity or a combination thereof, was declared effective.
Under the terms of the 1993 shelf registration statement, the 1992 shelf and a
1991 shelf, under which $394 million and $100 million, respectively, of
securities remained, were combined with the 1993 shelf. In November 1993,
United issued $118 million of pass through certificates under the shelf
registration to refinance aircraft under operating leases. In December 1993,
United issued $100 million of 6.75% debentures due 1997 under the shelf. On a
combined basis, up to $1.776 billion of additional securities may be offered at
December 31, 1993.
 
  The convertible debentures, which are obligations of Air Wis Services, Inc.
("Air Wis"), are convertible into shares of UAL common stock, at the conversion
price of $259.08 for $33 million and $198.02 for $3 million in principal
amount.
 
  In connection with 1993 aircraft financings, United issued $470 million of
secured notes due through 2013. Interest rates were fixed between 7.53% and
8.99% on $270 million of principal amount. Initial interest rates on the
remaining notes were 166 and 176 basis points over the London interbank offered
rate

("LIBOR") and will be 650 basis points over LIBOR after nine months. In
addition, during 1993, United retired $74 million of principal amount of
secured notes in connection with sale and leaseback transactions.
 
  At December 31, 1993, United had outstanding a total of $544 million of long-
term debt bearing interest at rates 85 to 176 basis points over LIBOR. In
connection with certain of these debt financings, United has entered interest
rate swap agreements to effectively fix interest rates at December 31, 1993
between 8.554% and 8.6% on $73 million of notional amount. The swap agreements
have terms of 18.5 years, corresponding to the terms of the related debt
obligations. Under the agreements, United makes payments to counterparties at
fixed rates and in return receives payments based on LIBOR. In the event of
default by the counterparties, United is exposed to credit risk for periodic
settlements due under the swap agreements; however, United does not anticipate
such default. The fair values of these swap agreements at December 31, 1993 and
1992 were $8 million and $3 million, respectively, representing the estimated
amount that United would pay to terminate the swap agreements, based on
interest rates in effect at the time.
 
  Maturities of long-term debt for each of the four years after 1994 are:
1995--$114 million; 1996--$117 million; 1997--$119 million; and 1998--$181
million.
 
  Various assets, principally aircraft, having an aggregate book value of
$1.713 billion at December 31, 1993, were pledged under various loan
agreements.
 
(9) LEASE OBLIGATIONS
 
  UAL leases aircraft, airport passenger terminal space, aircraft hangars and
related maintenance facilities, cargo terminals, flight kitchens, real estate,
office and computer equipment and vehicles.
 
  Future minimum lease payments as of December 31, 1993, under capital leases
and operating leases having initial or remaining noncancelable lease terms of
more than one year are as follows:

  As of December 31, 1993, United leased 298 aircraft, 45 of which were under
capital leases. These leases have terms of four to 26 years, and expiration
dates range from 1994 through 2017. Under the terms of leases for 287 of the
aircraft, United has the right of first refusal to purchase, at the end of the
lease term, certain aircraft at fair market value and others at either fair
market value or a percentage of cost. United has five

Airbus A320-200 aircraft under 24-year operating leases which are cancelable
upon eleven months notice during the initial 10 years of the leases.
 
  Amounts charged to rent expense, net of minor amounts of sublease rentals,
were $1.211 billion in 1993, $1.060 billion in 1992, and $855 million in 1991.
Included in rent expense for 1993 and 1992 were insignificant amounts of
contingent rentals, resulting from changes in interest rates for operating
leases under which the rent payments are based on variable interest rates. In
connection with certain of these leases, United has entered interest rate swap
agreements, with terms similar to those discussed in Note 8--Long-Term Debt. At
December 31, 1993, a notional amount of $415 million of interest rate swap
agreements effectively fixed interest rates between 8.02% and 8.65% on such
leases. The fair values of these swap agreements at December 31, 1993 and 1992
were $34 million and $8 million, respectively.
 
(10) FOREIGN OPERATIONS
 
  United conducts operations in various foreign countries, principally in the
Pacific, Europe and Latin America. Operating revenues from foreign operations
were approximately $5.560 billion in 1993, $4.863 billion in 1992 and $3.870
billion in 1991.
 
(11) PREFERRED STOCK
 
  UAL issued six million shares of cumulative 6.25% convertible preferred stock
in February 1993, resulting in net proceeds of $591 million. The convertible
preferred stock is convertible into UAL common stock at a conversion price of
$156.50 per share. Under its terms, any portion of the convertible preferred
stock is redeemable after April 30, 1996, at UAL's option, at $100 per share
plus a premium which begins at 4.375% declining to zero ratably over seven
years. The amount payable in the event of liquidation is $100 per share, plus
accrued dividends. UAL's retained earnings and additional capital invested are
restricted to the extent that the $600 million aggregate liquidation value
exceeds the stated value of the preferred stock.
 
  The preferred stock has voting rights only to the extent required by law and
with respect to charter amendments that adversely affect the preferred stock or
the creation or issuance of any stock ranking senior to the preferred stock.
Additionally, if dividends are not paid for six cumulative quarters, the
preferred shareholders are entitled to elect two additional members to the UAL
Board of Directors until all dividends are paid in full.
 
(12) COMMON SHAREHOLDERS' EQUITY
 
  At December 31, 1993 and 1992, there were 24,568,937 and 24,238,482 shares,
respectively, of UAL common stock outstanding. In February 1992, UAL issued
443,593 shares of common stock out of treasury in connection with the Air Wis
acquisition. The number of shares outstanding increased by 205,075 in 1993 and
40,464 in 1992 on exercises of stock options. In addition, 3,503 and 3,165
shares were issued out of treasury in 1993 and 1992, respectively, under other
compensation arrangements and 7,623 and 346 shares were acquired for treasury
in 1993 and 1992, respectively.
 
  There is a preferred share purchase right associated with each share of
outstanding UAL common stock. Upon the occurrence of certain events, each right
will entitle its holder to purchase one one-hundredth of a share of Series C
junior participating preferred stock, without par value, for $185 (subject to
antidilution provisions). The rights will become exercisable ten business days
after any person or group announces its beneficial ownership of 15% or more of
UAL common stock, or announces an offer for 30% or more of UAL common stock. If
any person or group acquires 15% or more of UAL common stock, each right will
entitle its holder (except the acquiring party) to buy common stock of UAL
having a market value of three

times the exercise price of the right. If, after the rights become exercisable,
UAL is involved in a merger or sells more than 50% of its assets, each right
will entitle its holder to buy common stock of the surviving entity having a
market value of three times the exercise price of the right. UAL has the right
to redeem the rights for $0.05 per right prior to the time they become
exercisable. The rights expire on December 31, 1996. The proposed employee
investment transaction is not expected to trigger the exercise rights in part
because the rights plan provides an exception for transactions like the
proposed employee investment transaction.
 
(13) STOCK OPTIONS AND AWARDS
 
  UAL's 1981 Incentive Stock Option Program, as amended, (the "1981 Plan"),
permits the issuance of up to 4,300,000 shares of common stock pursuant to
grants of "incentive stock options" under the Internal Revenue Code and to
grants of nonstatutory stock options. The option price for all stock options is
at least 100% of the fair market value of UAL common stock at the date of
grant.
 
  Prior to 1992, stock appreciation rights ("SARs") were granted in tandem with
certain nonstatutory stock options. On exercise of these SARs, holders would
receive, in cash, 100% of the appreciation in fair market value of the shares
subject to the SAR. The estimated payment value of SARs, net of market value
adjustments, was charged to earnings over the vesting period. In 1992, all
active officers relinquished their SARs but retained the tandem stock options.
At December 31, 1993, 13,927 SARs were outstanding with an average option price
per share of $76.25. The expense (credit) recorded for SARs was $1 million in
1993, $(1) million in 1992 and $18 million in 1991. In February 1994, UAL
reinstated the use of SARs and 818,370 SARs were authorized in tandem with
existing options with an outstanding average option price of $128.50. The SARs
are not exercisable until September 1, 1994, and will expire if the employee
investment transaction is consummated.
 
  Stock option activity under the 1981 Plan was as follows:

  The expiration dates for options outstanding as of December 31, 1993 ranged
from October 24, 1994 to October 28, 2003. At December 31, 1993, options
granted under the 1981 Plan were held by 126 officers and key employees.
 
  The 1988 Restricted Stock Plan (the "1988 Plan") permits the award of up to
500,000 shares of common stock to key officers and employees. During 1993 and
1991, 138,500 and 101,750 shares, respectively, were issued from treasury stock
and awarded under the 1988 Plan. No shares were issued under this plan during

1992. These restricted shares generally vest over a five-year period. Unvested
shares are subject to certain transfer restrictions and forfeiture under
certain circumstances. In 1993 and 1992, 9,000 and 6,500 shares, respectively,
were forfeited and returned to treasury stock. Unearned compensation,
representing the fair market value of the stock on the date of award, is being
amortized to salaries and related costs over the vesting period. As of December
31, 1993, 367,300 shares were outstanding under the 1988 Plan, of which 116,200
were vested and 132,700 shares remained available for award.
 
  In the event the proposed employee investment transaction discussed in Note 2
is consummated, additional stock options will become exercisable and unvested
restricted shares will vest. An amendment to the 1981 Plan includes terms which
will allow the cashless exercise of stock options in the event the employee
investment transaction is consummated.
 
(14) RETIREMENT PLANS
 
  United has various retirement plans which cover substantially all employees.
Defined benefit plans covering certain employees (primarily union ground
employees) provide a stated benefit for specified periods of service, while
defined benefit plans for other employees provide benefits based on employees'
years of service and average compensation for a specified period of time before
retirement. Pension costs are funded to at least the minimum level required by
the Employee Retirement Income Security Act of 1974. The company also provides
several defined contribution plans which cover substantially all U. S.
employees who have completed one year of service. For certain groups of
employees (primarily pilots), the company contributes an annual amount on
behalf of each participant, calculated as a percentage of the participants'
earnings or a percentage of the participants' contributions.
 
  The following table sets forth the defined benefit plans' funded status and
amounts recognized in the statement of consolidated financial position as of
December 31:

(15) POSTRETIREMENT BENEFITS
 
  United provides certain life insurance and health care benefits for
substantially all retired employees. The estimated cost of life insurance
benefits is accrued and funded over the years of service of those employees
expected to qualify for such benefits. United provides various defined benefit
postretirement health care plans which pay stated percentages of most necessary
medical expenses incurred by retirees, after subtracting payments by Medicare
or other providers and after a stated deductible has been met. United funds
this plan as medical claims are paid. Effective January 1, 1992, United adopted
SFAS No. 106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions". This standard requires that the expected cost of postretirement
benefits be charged to expense during the years in which employees render
service. Upon adoption, United elected to record the transition obligation of
$925 million as a one-time charge against earnings. Prior to 1992, the cost of
health care benefits was recognized as expense as claims were paid. The total
cost of these postretirement benefits was $33 million in 1991.

  For the valuation of the accumulated postretirement benefit obligation as of
December 31, 1993 and 1992, the discount rate was 7.5% and 8.75%, respectively.
An 11% and 12% annual rate of increase in the per capita cost of covered health
care was assumed for 1993 and 1992, respectively; the rate is assumed to
decrease annually to a rate of 4% by the year 2001, remaining level thereafter.
The effect of a 1% increase in the assumed health care cost trend rate would
increase the accumulated postretirement benefit obligation at December 31,
1993, by $175 million and the aggregate of the service and interest cost
components of net postretirement benefit cost for 1993 by $21 million.
 
(16) COMMITMENTS AND CONTINGENCIES
 
  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 December 31, 1993, commitments for the purchase of property and equipment,
principally aircraft, approximated $4.3 billion after deducting advance
payments. An estimated $0.6 billion is expected to be expended during 1994,
$1.1 billion in 1995, $0.8 billion in 1996, $1.2 billion in 1997, $0.4 billion
in 1998, and $0.2 billion after 1998. The major commitments are for the
purchase of thirty-four B777 aircraft, which are expected to be delivered
between 1995 and 1999. These amounts reflect United's revised capital spending
plan and agreements with The Boeing Company, to convert certain aircraft orders
into options. Under the terms of the agreements, if United does not elect to
confirm the delivery of these option aircraft before 1998, it will forfeit
significant deposits.
 
  In addition to the B777 order, United has arrangements with Airbus and
International Aero Engines to lease an additional 45 A320 aircraft, which are
scheduled for delivery through 1998. Under the agreement, United is making
advance payments through 1996 which are refundable upon delivery of each
aircraft.
 
  At December 31, 1993, United also had purchase options for 186 B737 aircraft,
54 B757 aircraft, 34 B777 aircraft, 52 B747 aircraft, eight B767 aircraft and
50 A320 aircraft. Consistent with its revised capital spending plan, United has
recently cancelled options on certain aircraft. In January 1994, United entered
an agreement with Boeing to acquire two B747-400 aircraft in 1994 and cancelled
options for two B747 aircraft. These aircraft are not included in the
commitment amounts above.
 
  As of December 31, 1993, United had guaranteed $97 million of indebtedness of
affiliates. Special facility revenue bonds have been issued by certain
municipalities to build or improve airport facilities leased by United. Under
the lease agreements, United is required to make rental payments in amounts
sufficient to pay the maturing principal and interest payments on the bonds. At
December 31, 1993, $907 million principal amount of such bonds was outstanding.
Payment of United's obligations with respect to $40 million of this amount is
secured through standby letters of credit. As of December 31, 1993, UAL and
United had jointly guaranteed $35 million of such bonds and United had
guaranteed $841 million of such bonds, including accrued interest. Included in
this amount are bonds issued by the City of Denver in connection with the
construction of certain United facilities at Denver International Airport,
which will replace Stapleton International Airport ("Stapleton"). Denver has
agreed to retire the outstanding special facility revenue bonds related to
United's Stapleton facilities. The new airport is expected to open in 1994.
 
  Transfers of the tax benefits of accelerated depreciation and investment tax
credits associated with the acquisition of certain equipment have been made
previously by United to various tax lessors through tax lease

transactions. Proceeds from tax benefit transfers were recognized as income in
the year the lease transactions were consummated. The subject equipment is
being depreciated for book purposes. United has agreed to indemnify (guaranteed
in some cases by UAL) the tax lessors against loss of such benefits in certain
circumstances and has agreed to indemnify others for loss of tax benefits in
limited circumstances for certain used aircraft purchased by United subject to
previous tax lease transactions. Certain tax lessors have required that letters
of credit be issued in their favor by financial institutions as security for
United's indemnity obligations under the leases. The outstanding balance of
such letters of credit totaled $68 million at December 31, 1993. At that date,
United had granted mortgages on aircraft and engines having a total book value
of $252 million as security for indemnity obligations under tax leases and
letters of credit.
 
  United is in the process of constructing a maintenance facility in
Indianapolis, which begins operation in 1994. The facility is being financed
primarily with tax-exempt bonds and other capital sources. In connection with
incentives received, United has agreed to reach an $800 million capital
spending target and employ at least 6,300 individuals.
 
  UAL does not believe it is subject to any significant concentration of credit
risk. Most of UAL's receivables result from sales of tickets to individuals
through travel agents, company outlets or other airlines, often through the use
of major credit cards. These receivables are short term, generally being
settled shortly after the sale.
 
(17) NEW ACCOUNTING STANDARDS
 
  In November 1992, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 112, "Employers' Accounting for Postemployment Benefits," which
requires recognition of the liability for postemployment benefits during the
period of employment. Such benefits include company paid continuation of group
life insurance and medical and dental coverage for certain employees after
employment but before retirement. UAL will adopt the new standard in the first
quarter of 1994. Based on preliminary estimates, UAL currently expects to
record a transition obligation which will result in a cumulative charge of $26
million, net of tax. Prior years' financial statements will not be restated.
Ongoing expenses will vary based on actual claims experience.
 
  In May 1993, the FASB issued SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," which requires fair value
accounting for certain investments. UAL is required to adopt the new standard
in 1994 and the standard is not to be applied retroactively. Upon adoption, UAL
will record a periodic charge or credit to adjust the carrying value of certain
investments to fair value. The adjustment will be recorded in earnings or as a
separate component of equity, depending on the type of investment. UAL does not
expect a material impact on either earnings or equity as a result of adopting
SFAS No. 115.

(19) OTHER MATTERS
 
  Air Wis became a wholly-owned subsidiary of UAL in January 1992. Air Wis owns
Air Wisconsin, Inc. A combination of cash and UAL common stock, valued at $80
million, was exchanged for all the outstanding shares of Air Wis. The
transaction was accounted for as a purchase and, accordingly, the assets and
liabilities of Air Wis were recorded based on fair value estimates which
resulted in tangible assets of $218 million, intangible assets of $125 million
and liabilities of $246 million, net of $12 million of intercompany amounts.
The UAL consolidated financial statements include the accounts of Air Wis from
February 1, 1992. In September 1992, Air Wisconsin, Inc. consummated the $32
million sale of 12 slots at O'Hare International. The fair value amounts above
reflect the sale.
 
  In April 1993, UAL transferred the Air Wisconsin, Inc. operations at Dulles
to Atlantic Coast Airlines. In September 1993, UAL transferred certain Air
Wisconsin, Inc. operations at O'Hare to United Feeder Services. In December
1993, UAL transferred the jet operations of Air Wisconsin, Inc. to CJT
Holdings. These operations are being conducted by the counterparties in these
agreements under the United Express trade name. These transactions are not
expected to have a significant impact on UAL's results of operations.
 
  In the third quarter of 1993, United reached agreements to sell assets
related to the operation of 16 of its flight kitchens to Dobbs International
Services, Inc. and Caterair International Corp. for $119 million. Under the
agreements, the purchasers will provide catering services for United at the
airports served by the flight kitchens for seven years. The asset sales for
most, if not all, of the flight kitchens are expected to be finalized in the
second quarter of 1994. The asset sales result in an insignificant gain.

  In the second quarter of 1993, United retired $500 million of senior
subordinated notes. An extraordinary loss of $19 million, net of tax benefits
of $8 million, was recorded in the first quarter of 1993, based on United's
stated intention to retire the notes.
 
  In the third quarter of 1993, UAL recorded a charge of $59 million to reduce
the net book value of 15 DC-10 aircraft to estimated net realizable value. In
addition, third quarter earnings included a $17 million gain and interest
income of $27 million resulting from the final settlement for overpayment of
annuities purchased in 1985 to cover certain vested pension benefits. The 1993
fourth quarter included $53 million of equity in the loss of Galileo, which
primarily reflects United's share of a charge recorded by Galileo for the cost
of eliminating duplicate facilities and operations.
 
  Effective January 1, 1992, UAL adopted SFAS No. 106, "Employers' Accounting
for Postretirement Benefits Other than Pensions" and SFAS No. 109, "Accounting
for Income Taxes." The effect of adopting SFAS No. 106 was a cumulative charge
of $580 million, net of tax benefits of $345 million. The effect of adopting
SFAS No. 109 was a cumulative benefit of $40 million.
 
  In the 1992 fourth quarter, operating expenses included charges of $18
million for certain foreign employee benefits and certain taxes. In addition,
operating expenses included charges of $25 million related to the announced
cost reduction program. The 1992 second quarter included a $13 million non-
operating charge to record the cash settlement of class action claims resulting
from litigation relating to the use of airline fare data.

  Primary earnings per share in the 1993 quarters were calculated after
preferred dividend requirements of $6 million in the first quarter and $9
million in each of the last three quarters. Primary earnings per share are
based on the weighted average number of shares of common stock outstanding
during the period. Fully diluted earnings per share assume conversion of the
preferred stock and elimination of the dividends. Fully diluted earnings per
share were anti-dilutive in the 1993 first, second and fourth quarters and
year.
 
  The sum of quarterly earnings per share amounts is not the same as annual
earnings per share amounts because of changing numbers of shares outstanding.

responsibility for effecting these filings.
 
ITEM 11. EXECUTIVE COMPENSATION
 
COMPENSATION OF DIRECTORS
 
  The directors receive an annual retainer of $20,000 and are paid $1,000 for
each meeting attended. The Chairmen of the Audit, Compensation, Nominating and
Pension and Welfare Plans Oversight Committees each receive an additional
retainer of $3,000 per year. Each member of a committee receives a fee of
$1,000 for each committee meeting attended. In support of a cost reduction
effort announced in January 1993, directors' compensation as reported above was
reduced 10%. Directors also receive 100 shares of Common Stock, $5 par value
("Common Stock"), annually. Directors who are officers of the Company or of any
subsidiary do not receive any retainer fee, meeting fee or shares for their
service on the Board of Directors or any committee.
 
  Non-employee directors are eligible to participate in a retirement income
plan (the "Retirement Plan") if they have at least five years of service on the
date of retirement and are not otherwise eligible to receive pension benefits
from the Company or any of its subsidiaries. If a retiring director has at
least ten years of service and is age 70 or over at retirement, he or she is
entitled to a life annuity equal to the greater of $20,000 per year or the
annual retainer fee at retirement. Reduced benefits are available if the
director has less than ten years of service or if retirement occurs before age
70. For these purposes a director who is a director at the time of a "change in
control" of the Company is credited with three additional years of service, is
deemed to have satisfied the five-year minimum service requirement and is
deemed to be three years older than his or her actual age. Surviving spouse
benefits are available in some cases. A trust (the "Trust") has been created to
serve as a source of payments of benefits under the Retirement Plan. The Trust
becomes irrevocable upon the occurrence of a "change in control."
 
  Under the Company's travel policy for directors (the "Travel Policy"), each
director of the Company, his or her spouse and their eligible dependent
children are entitled to free transportation on United. The directors are
reimbursed by the Company for additional income taxes resulting from the
taxation of these benefits. The average cost of supplying these benefits for
each director in 1993, including cash payments made in January, 1994 for income
tax liability, was $25,300. The Company also has a policy pursuant to which
each director is entitled to free cargo shipment on United. A director (and his
or her spouse and eligible dependent children) serving as such at the time of a
"change in control" is entitled to continue such benefits thereafter for life.

  The above illustration is based on retirement at age 65 and selection of a
straight life annuity (other annuity options are available, which would reduce
the amounts shown above). The amount of the normal retirement benefit under
the plan is the product of 1.6% times years of credited participation in the
plan times final average compensation (highest five of last ten years of
covered compensation). The retirement benefit amount is not offset by the
participant's Social Security benefit. Compensation covered by the
plan includes salary and cash bonuses. Credited years of participation with
the Company and United for persons named in the cash compensation table are as
follows: Mr. Wolf--5 years; Mr. Pope--5 years; Mr. Guyette--25 years; Mr.
O'Gorman--21 years; and Mr. Nagin--4 years. The amounts shown do not reflect
limitations imposed by Internal Revenue Code on retirement benefits which may
be paid under plans qualified under the Internal Revenue Code. United has
agreed to provide under non-qualified plans the portion of the retirement
benefits earned under the pension plan which would otherwise be subject to
Internal Revenue Code limitations.
 
  The Company has agreed to supplement Messrs. Wolf's and Pope's benefits
under the qualified pension plan and United has agreed to supplement Messrs.
Nagin's and O'Gorman's benefits under the qualified pension plan, in each case
by granting them credit for their prior airline service--22 years for Mr.
Wolf, 10 years for Mr. Pope, 6 years for Mr. O'Gorman, and 8 years for Mr.
Nagin. Mr. Wolf's benefit will be offset by retirement benefits he is entitled
to under any of the plans of his prior employers except Tiger International,
Inc.

EMPLOYMENT CONTRACTS AND CHANGE IN CONTROL ARRANGEMENTS
 
  The Company and United originally entered into employment agreements with Mr.
Wolf and Mr. Pope when they joined the Company in 1987 and 1988, respectively
(as subsequently amended and restated, the "Employment Agreements").
 
  In the event of a change in control of the Company or United followed by the
termination of his employment, Mr. Wolf would be entitled to a payment equal to
from one to three times his salary and anticipated bonus deemed equal to his
salary, depending upon the circumstances of his termination, together with
certain other amounts. In the event of a change in control of the Company or
United followed by a termination of his employment, Mr. Pope would be entitled
to a payment equal to from one to three times his salary and anticipated bonus
of not less than $100,000, depending upon the circumstances of his termination,
together with certain other amounts.
 
  The Employment Agreements also provide for the continuance of certain
specified employee benefits for a period of years equal to the number of years
of compensation included in the severance payment and, depending on the
circumstances applicable to an executive, possibly beyond that time.
 
  Each other named executive officer is a party to a severance agreement (the
"Severance Agreements") with United that provides certain benefits if the
executive's employment with United is terminated (1) by the Company without
"cause" (as defined in the Severance Agreements) or (2) by the executive for
"good reason" (as defined in the Severance Agreements) in either case, within
three years following a "change in control" (as defined in the Severance
Agreements). Upon such a termination of employment, the executive officer will
be entitled to receive (1) a cash payment equal to 3 times the sum of (a) the
greater of the executive's base salary as in effect on the date of the change
in control or as in effect on the date his or her employment terminates plus
(b) the average of the greater of the bonuses paid to the executive with
respect to the three years preceding the change in control or the bonuses paid
to the executive with respect to the three years preceding his or her
termination of employment, (2) continuation of travel privileges (and partial
tax reimbursement) on United for the executive and his or her spouse and other
dependents for three years following termination of employment (and for life
thereafter if the executive would have qualified for retiree travel privileges
has his or her employment continued during such three-year period), (3)
coverage under United's medical and other welfare benefits for a period of
three years following the date of termination (and for life thereafter if the
executive would have qualified for retiree medical benefits had his or her
employment continued during such three-year period), (4) a lump sum payment
equal to the value of the pension benefits (including any early retirement
benefits) that the executive officer would have earned under United's pension
plans and arrangements had the officer continued to be employed for an
additional three years and (5) a lump sum payment equal to the amounts that
United would have paid on behalf of the executive officer with respect to split
dollar life insurance policies in effect for the executive.
 
  During 1993 the Company amended stock option and restricted stock agreements
with each of the named executive officers to provide for the automatic vesting
of outstanding stock options, and for confirmation of such treatment for
restricted stock awards, upon a change in control.

ITEM 1. BUSINESS
 
 Introduction
 
  United Air Lines, Inc. ("United" or the "Company") was incorporated under the
laws of the State of Delaware on December 30, 1968. The executive offices of
the Company are located at 1200 Algonquin Road, Elk Grove Township, Illinois
60007. The Company's mailing address is P.O. Box 66100, Chicago, Illinois
60666. The telephone number for the Company is (708) 952-4000.
 
  United is the principal subsidiary of UAL Corporation ("UAL"), and is wholly-
owned by UAL. United accounted for virtually all of UAL's revenues and expenses
in 1993. United is a major commercial air transportation company.
 
 Proposed Employee Investment Transaction
 
  On December 22, 1993, the Board of Directors of UAL approved an agreement in
principle (as amended, the "Agreement in Principle") with the Air Line Pilots
Association ("ALPA") and the International Association of Machinists ("IAM")
concerning a proposed transaction (the "Employee Investment Transaction") that
would provide a majority equity interest in UAL to certain of the employees of
United in exchange for wage and benefit concessions and work-rule changes. In
January 1994, ALPA and the IAM ratified the Agreement in Principle. The
Employee Investment Transaction is subject to, among other conditions,
execution of definitive documentation and approval by UAL's stockholders.
 
  The proposed Employee Investment Transaction is intended to put in place a
lower cost structure that allows United to compete effectively in domestic
markets and improve its long-term financial competitiveness. The concessions
would come from three of United's employee groups: employees represented by
ALPA, employees represented by the IAM, and the salaried and management
employees. Employees represented by the Association of Flight Attendants
("AFA") have been invited to participate in the transaction, and
representatives of UAL have engaged in discussions with AFA representatives
concerning such participation but the transaction does not require their
participation to proceed.
 
  In the proposed transaction, an employee stock ownership plan ("ESOP") would
be created to provide United employees with a minimum of a 53% equity interest
in UAL in exchange for wage and benefit concessions and work-rule changes. The
employee interest could increase to up to 63%, depending on the average market
value of UAL's common stock in the year after the transaction closes. The
transaction would not be dependent on external financing.
 
  Pursuant to the terms of the Agreement In Principle, current stockholders of
UAL would receive the remaining 37% to 47% of the new common stock and $88 per
share of cash and face amount of debt and preferred stock. The transaction
would provide for the creation of a low-cost short-haul operation to compete in
domestic markets. For additional information concerning the Agreement in
Principle and the proposed Employee Investment Transaction, see Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operation".
 
 Recent Developments
 
  In January 1994, United entered into an agreement with The Boeing Company
("Boeing") to acquire two new B747-400 aircraft in 1994, in place of options
for two similar aircraft (see "Flight Equipment" in Item 2, Properties).
 
  In March 1994, United opened a new major aircraft maintenance and overhaul
facility ("MOC-II") in Indianapolis. Operating under a lease with the
Indianapolis Airport Authority which expires November 30, 2031, when all phases
of the construction work are completed United will occupy approximately 300
acres of
 
                                       2
<PAGE>
 
land and up to three million square feet of space, including 15 aircraft dock
positions. MOC-II will be used for maintenance of Boeing 737 aircraft, engine
repair, spare parts storage, ground equipment maintenance, technical support
and administrative functions.
 
 Airline Operations
 
  United has been engaged in the air transportation of persons, property and
mail since 1934, and certain of its predecessors began operations as early as
1926. United is one of the world's largest investor-owned airlines as measured
by operating revenues, revenue passengers and revenue passenger miles flown. At
the end of 1993, United served 159 airports in the United States and 32 foreign
countries. During 1993, United averaged 2,040 departures daily, flew a total of
101 billion revenue passenger miles, and carried an average of 191,000
passengers per day.
 
  United provides service to its domestic and international markets principally
through a system of hub airports at major cities. Each hub provides United
flights to a network of spoke destinations as well as flights to other United
hubs. This arrangement permits travelers to fly from point of origin to more
destinations without switching carriers. Currently, United flies from four U.S.
hubs--Chicago-O'Hare International ("O'Hare"), Denver, San Francisco
International, and Dulles International near Washington, D.C. ("Dulles")--and
is the principal carrier at each of these hubs. United also has a Pacific hub
operation at Tokyo Narita airport, and an Atlantic hub operation at London
Heathrow Airport. During the last several years, United has strengthened the
revenue-generating capability of the hub airports by: (1) adding new spokes
(new cities and airports); (2) adding frequency on previously operated route
segments; and (3) entering into marketing agreements with smaller U.S. air
carriers which serve less populated destinations and with foreign carriers
which serve destinations that United could not serve economically itself.
 
  United has developed a route system covering North America, Asia, the South
Pacific, Europe and Latin America.
 
  Within North America, East-West traffic is served by nonstop Transcontinental
flights and by the hubs at Chicago O'Hare and Denver, while North-South traffic
on the West Coast is served by the San Francisco hub.
 
  Within North America, United has a marketing program with selected
independent regional air carriers, known as the United Express ("UE") program,
which allows United to increase the number of destinations served by its hub-
and-spoke network. Six regional carriers currently participate in the UE
marketing program providing connecting schedules to ten major cities also
served by United: Air Wisconsin Airlines Corporation to Chicago and Denver;
UFS, Inc. to Chicago; Mesa Airlines, Inc. to Denver and Los Angeles; WestAir
Commuter Airlines, Inc. to San Francisco, Los Angeles, Seattle and Portland,
Oregon; Great Lakes Aviation to Chicago, Denver and Minneapolis; and Atlantic
Coast Airlines, Inc. to Washington-Dulles, Newark and Orlando. Connecting
schedules of three of these carriers result in part from separate transfers to
them in 1993 of operating assets of Air Wisconsin, Inc., which is an indirect
subsidiary of UAL Corporation.
 
  Within North America, United also has marketing agreements that provide for
sharing of the "UA" code on certain routes with two other domestic air
carriers, Trans World Express ("TWE") and Aloha Airlines. Code-sharing allows
an airline to expand the marketing of its service brand by using its two-letter
designator code to designate in computerized reservations systems a connecting
flight operated by another airline on the itinerary. Under these agreements,
the UA designator code is reflected on TWE flights between approximately 20
cities in the Northeast U.S. which connect with United's international flights
in and out of New York John F. Kennedy International Airport ("Kennedy"), and
on Aloha Airlines' flights between and among the Hawaiian Islands in connection
with United's flights in and out of Hawaii. Finally, North American traffic is
also served by code-sharing agreements United has with two Caribbean air
carriers, ALM and Sunaire, under which each reflects the United designator code
on its flights.
 
  Asian traffic is served from six U.S. cities via the Tokyo hub and with
nonstop flights from San Francisco to Hong Kong, Osaka, Seoul and Taipei; from
Honolulu to Osaka; and, beginning in 1993, from Los Angeles
 
                                       3
<PAGE>
 
to Hong Kong, and from Chicago to Seoul. Effective October 1994, United plans
to offer nonstop service between Los Angeles and Osaka and, as soon as
government approvals are received, service between Los Angeles and Ho Chi Minh
City, Vietnam, via Taipei. South Pacific traffic to Auckland, Melbourne and
Sydney is served from Los Angeles. United plans to begin nonstop service
between San Francisco and Sydney beginning in June 1994 (subject to the
approval of the Australian government), further strengthening United's San
Francisco international hub and supplementing United's Los Angeles to Sydney
service. United also has code-sharing agreements with two South Pacific air
carriers, Ansett Australia and Ansett New Zealand. Based on reports filed with
the Department of Transportation, United was the leading U.S. carrier in the
Pacific in 1993 in terms of revenue passenger miles. During 1993, United's
Pacific Division accounted for 25% of United's revenues.
 
  Service between the U.S. and Europe is provided by: flights from six U.S.
cities to the London hub, with connecting service at London to several European
cities; flights from four U.S. cities to Paris, with connecting service to two
European cities; and nonstop service from Dulles to Brussels, Frankfurt,
Madrid, Milan/Rome and, beginning in 1993, to Amsterdam, Glasgow and Zurich;
and from Chicago to Frankfurt. European traffic is also served by United's
code-sharing agreements with British Midland and Emirates. In addition, in 1993
a comprehensive marketing agreement was signed with Germany's flag carrier,
Lufthansa, and is awaiting governmental approvals. If approved, this worldwide
alliance would, among other things, allow code-sharing between the two airlines
on Transatlantic route segments, and would permit United to code-share on
Lufthansa flights to eight cities in Germany beyond Frankfurt (Berlin, Cologne,
Dusseldorf, Hanover, Hamburg, Munich, Nuremberg and Stuttgart), as well as
Vienna. Similarly, the agreement would permit Lufthansa to code-share on United
flights to eleven cities in the U.S.--five beyond Chicago, five beyond
Washington, D.C., and one beyond San Francisco. A 1993 agreement to acquire
USAir's Philadelphia-London route was terminated due to the transaction's
failure to receive the requisite governmental approvals.
 
  Service between the U.S. and Latin America is provided by flights to 14 Latin
American cities in 11 countries from a number of cities in the U.S. Ten Latin
American cities are served nonstop from Miami, three nonstop from Los Angeles
and four from New York-Kennedy. United also has a code-sharing agreement with
Transbrasil.
 
  Operating revenues attributed to United's foreign operations were
approximately $5.6 billion in 1993, $4.9 billion in 1992 and $3.9 billion in
1991.

 Industry Conditions
 
  Seasonal and Other Factors. United's results of operations for interim
periods are not necessarily indicative of those for an entire year, since the
air travel business is subject to seasonal fluctuations. United's first and
fourth quarter results normally are affected by reduced travel demand in the
fall and winter, and United's operations, particularly at its O'Hare and Denver
hubs, are often affected adversely by winter weather. In the past, these
fluctuations have generally resulted in better operating results for United in
the second and third quarters. See Item 8, "Financial Statements and
Supplementary Data," for summarized unaudited financial data for the four
quarters of 1993 and 1992 incorporated by reference therein.
 
  The results of operations in the air travel business have also fluctuated
significantly in the past in response to general economic conditions. In
addition, the airline business is characterized by a high degree of operating
leverage. As a result, the economic environment and small fluctuations in
United's yield per revenue passenger mile and cost per available seat mile can
have a significant impact on operating results. The Company anticipates that
seasonal factors and general economic conditions, in addition to industrywide
fare levels, labor and fuel costs, the competition from other airlines with
lower operating costs than United's international government policies, and
other factors, will continue to impact United's operations.
 
  Competition and Fares. The airline industry is highly competitive. In
domestic markets, new and existing carriers are free to initiate service on any
route. United faces competition from other carriers on virtually every route it
serves. In United's domestic markets, these competitors include all of the
other major U.S. airlines as well as smaller carriers.
 
  United's marketing strategy is driven by four principal competitive factors:
schedule convenience, overall customer service, frequent flyer programs and
price. United seeks to attract travelers through convenient scheduling
(particularly during peak demand periods), high quality service, frequent flyer
programs designed to reward customer loyalty, and competitive pricing.
 
  During 1993, certain domestic carriers, both in and out of bankruptcy
proceedings, reorganized their operating cost structures. These carriers,
together with more recent entrants to the airline business, and a select number
of established domestic carriers, currently have cost structures significantly
lower than United's, and therefore may be able to operate profitably at lower
fare levels. Furthermore, certain carriers in the short-to-medium distance
domestic markets have been able to compete against major air carriers,
including United, by operating without as great a reliance upon a hub-and-spoke
system. These airlines operate efficiently through strategies such as rapid
turnaround of flights on a point-to-point basis. The success of these carriers
and such strategies has led certain major carriers, including United, to
consider ways in which to reorganize their short-haul operations to allow them
to compete more effectively in domestic markets.
 
  From time to time, excess aircraft capacity and other factors such as the
cash needs of financially distressed carriers induce airlines to engage in
"fare wars." Such factors can have a material adverse impact
 
                                       5
<PAGE>
 
on the Company's revenues. The Company maintains yield and inventory management
programs designed to manage the number of seats offered in various fare
categories in order to enhance the effectiveness of fare promotions and
maximize revenue production on each flight.
 
  In order to improve its ability to compete effectively in the markets that it
serves, United has taken several steps to reduce its costs and capital
expenditures. In January 1993, United announced a cost reduction program, which
included the layoff of 2,800 employees in February 1993. In 1993 United reached
agreement with Boeing to convert 49 Boeing aircraft orders into options and
delay delivery of certain of the Boeing aircraft. United also reached agreement
with Airbus Industrie ("Airbus") to delay delivery of 14 A320s originally
scheduled for delivery after 1994. In addition, United announced in 1993 that
it would accelerate the retirement of 25 widebody aircraft. United also
negotiated over $100 million in annual savings from suppliers. Finally, in 1993
United reached agreements to sell assets related to the operation of 16 of its
flight kitchens to Dobbs International Services, Inc. and Caterair
International Corp. for $119 million in a series of phased closings which are
expected to be completed by mid-1994.
 
  The Employee Investment Transaction, if consummated, contemplates the
creation of a low-cost, short-haul operation within United to compete more
effectively in domestic markets and improve its long-term financial competitive
position.
 
  In its international markets, United competes with major U.S. carriers as
well as investor-owned and national flag carriers of foreign countries.
Competition in certain international markets is subject to varying degrees of
governmental regulation (see "Government Regulation"), and in certain instances
United's foreign competitors enjoy subsidies and other forms of governmental
support which are not available to U.S. carriers.
 
  United and other U.S. carriers have certain advantages over foreign air
carriers in their ability to generate U.S.-origin-destination traffic from
their integrated domestic route systems. However, the U.S. carriers are in many
cases constrained from carrying passengers to points beyond designated gateway
cities in foreign countries due to limitations in the bilateral air service
agreements with such countries or restrictions imposed unilaterally by the
foreign governments. To the extent that foreign competitors can offer more
connecting services to points beyond these gateway cities, they have an
advantage in attracting traffic moving between these foreign points and in
attracting traffic moving between such cities and points in the United States.
Also, several foreign air carriers have sought and obtained access to the U.S.
domestic market through substantial equity investments and code sharing
arrangements with U.S. airlines. The comprehensive marketing agreement signed
in 1993 with Germany's flag carrier, Lufthansa, if approved, is also expected
to enhance the Company's competitive position in international markets.
 
  No material part of the business of United and its subsidiaries is dependent
upon a single customer or very few customers. Consequently, the loss of the few
largest customers of United would not have a material adverse effect on the
Company.
 
  Airport Access. United's operations at its principal domestic hub, Chicago-
O'Hare International Airport ("O'Hare"), as well as at three other airports,
Kennedy, New York LaGuardia ("LaGuardia"), and Washington National
("National"), are limited by the "high density traffic airports rule"
administered by the Federal Aviation Administration ("FAA"). Under this rule,
take-off and landing rights ("slots") required for the conduct of domestic
flight operations may be bought, sold or traded. As of December 31, 1993,
United held 753 domestic air carrier slots at O'Hare, 43 at National, 65 at
LaGuardia and 11 at Kennedy. In addition, Air Wisconsin, Inc. held (or owned
the beneficial interest in) 38 air carrier slots and 118 commuter slots at
O'Hare which are either operated by United or leased to United Express carriers
serving O'Hare. Under the high density rule carriers are required to relinquish
slots to the FAA for reallocation if they fail to meet certain minimum use
standards.
 
  Slots for international services at O'Hare are allocated by the FAA
seasonally to both U.S. and foreign carriers based upon the carriers'
historical operations and requests for additional capacity. The FAA holds a
certain number of slots in reserve for this purpose. Slots over that number are
provided through the
 
                                       6
<PAGE>
 
withdrawal of domestic slots from carriers at O'Hare and the reallocation of
those slots for international operations of requesting carriers. United has
lost as many as 33 daily slots--that is, slots that were being used by United
three days or more per week--during a single operating season.
 
  During 1993, Congress amended the U.S. Department of Transportation ("DOT")
appropriations bill for fiscal year 1994. This legislation capped for that
fiscal year the number of slots that could be withdrawn from U.S. carriers for
allocation to international operations. Also, in November 1991, United
petitioned the FAA for a repeal of the international slot withdrawal provisions
of the regulations. This petition has not, however, been acted upon by the
agency. United believes that the number and distribution of slots it holds at
the airports subject to the high density rule are sufficient to support its
current operations. There can be no assurance, however, that additional slots
sufficient to accommodate otherwise desirable service expansions will be
available to United on satisfactory terms in the future. There is also no
assurance that the current slot regulations will remain in effect. If an
alternative to the current system were to be adopted, no assurance can be given
that such alternative would preserve United's investment in slots already
acquired or that slots adequate for future operations would be available.
 
  United believes that, at present, it has a sufficient number of leased gates
and other airport facilities at the cities it serves to meet its current and
near term needs. From time to time, expansion by United at certain airports may
be constrained by insufficient availability of gates on attractive terms.
United's ability to expand its international operations in Asia, the South
Pacific, Europe and Latin America is subject to restrictions at many of the
airports in these regions, including noise curfews, slot controls and absence
of adequate airport facilities.
 
  At Los Angeles and elsewhere, United and other airlines face continuing
disputes as to the level of landing fee rates and other charges for airport
operations. Recently, some of these rates and charges have escalated rapidly.
 
  Mileage Plus Program. United operates a frequent flyer marketing program
known as "Mileage Plus" wherein credits are earned by flying on United or using
the services of one of the other airlines, credit card companies, car rental
agencies and hotels (the "Partners") participating in the Mileage Plus program.
The program is designed to enable United to retain and increase the business of
frequent travelers. Credits earned under the program may be exchanged at
certain plateaus for free travel or service upgrades on United or for use with
one or more of the Partners.
 
  When an award level is attained, United records a liability for the
incremental costs of accrued credits under the Mileage Plus program based on
the expected redemptions. United's incremental costs include the costs of
providing service for an otherwise vacant seat including fuel, meals, certain
incremental personnel and ticketing costs. The incremental costs do not include
any contribution to overhead or profit. Awards earned after July 1989 have an
expiration date three years from date earned. The program also contains certain
restrictive provisions, including blackout dates and capacity controlled
bookings, which substantially limit the use of the awards on certain flights.
 
  In 1993 United announced that the mileage levels for Mileage Plus domestic
award travel would be increased on a prospective basis. As revised in January
1994, the Mileage Plus rules will require 25,000 miles, instead of the 20,000
miles now required, for award tickets issued for economy class travel within
the continental United States. Other mileage award level changes were also
announced, as was a change to a bank-account type of system to track mileage;
all changes are scheduled to take effect February 1, 1995.
 
  Lawsuits challenging these changes and changes to American Airlines' frequent
flyer program are pending in Illinois. While United believes that it has the
right to make the aforementioned changes to its program, and is defending
itself vigorously in the pending litigation, an adverse court decision could
restrict United's ability to alter award levels now or in the future.
 
  At December 31, 1993 and 1992, United estimated that the total number of
outstanding awards was approximately 7.7 million and 7.4 million, respectively.
United estimated that 5.8 million and 5.5 million,
 
                                       7
<PAGE>
 
respectively, of such awards could be expected to be redeemed and, accordingly,
had recorded a liability amounting to $205 million and $207 million,
respectively, at December 31, 1993 and 1992. The difference between the awards
expected to be redeemed and the total awards outstanding is the estimate, based
on historical data, of awards (1) which will never be redeemed, (2) which will
be redeemed for other than free trips, or (3) which will be redeemed on partner
carriers.
 
  The number of awards used on United were 1.6 million, 1.4 million and 1.6
million for the years 1993, 1992 and 1991, respectively. Such awards
represented 7.5%, 6.7% and 6.7% of United's total revenue passenger miles for
each period, respectively. With these low percentages, seat availability and
restrictions on the use of free travel awards, United believes that the
displacement, if any, of revenue passengers by users of Mileage Plus awards is
minimal.
 
  United has agreements with certain air carriers and other parties to utilize
the Mileage Plus program and receives and makes payments based on the earning
and redemption of awards by Mileage Plus participants with such parties.
 
  Computer Reservations Systems. Travel agents account for a substantial
percentage of United's sales. The complexity of the various schedules and fares
offered by air carriers has fostered the development of electronic distribution
systems that display information relating the fares and schedules of United and
other airlines to travel agents and others. United believes that the use of
such systems has been a key factor in the marketing and distribution of
airlines' products.
 
  Before September 1993, United had an ownership interest in two general
partnerships which owned and marketed computer reservation system ("CRS")
products and services. In September 1993, The Covia Partnership ("Covia"), a
50%-owned affiliate of United, and The Galileo Company Limited, a 25.6%-owned
affiliate of United, combined. In the combination Covia was renamed as "Galileo
International Partnership" ("Galileo"), and a second entity, the Apollo Travel
Services Partnership ("ATS"), was formed. These two general partnerships are
owned 38% and 77%, respectively, by United through a wholly-owned subsidiary.
 
  Galileo is held 50% by European carriers and 50% by North American carriers.
It owns the Apollo and Galileo CRSs and markets CRS services worldwide through
a system of national distribution companies located in countries in which
Galileo operates and which are usually owned by the Galileo partner airline
resident in a particular country, or if there is none, by Galileo or a local
contractor. Galileo is used by approximately 30% of the travel agent locations
outside North America, where it has over 42,000 terminals at more than 14,000
locations.
 
  ATS, which is held solely by the North American carriers, is responsible for
marketing, sales and support of Apollo CRS products and services in the United
States, Mexico and the Caribbean. A third entity, Galileo Japan Partnership, a
50%-owned affiliate of United, was also formed in September 1993 for the
purpose of distributing CRS services in Japan.
 
  In Canada, Apollo is distributed as the "Apollo by Gemini" product sold by
the Gemini Group Limited Partnership ("Gemini"), in which Galileo owned a one-
third interest. Gemini is under a court order to dissolve by November 1994, and
Air Canada has agreed to acquire Galileo's interest in Gemini. Galileo is in
discussions concerning an alternative distribution of its CRS products and
services in Canada.
 
  Competition among CRS vendors is intense, and services similar to these
offered by Galileo are marketed by several air carriers and other concerns,
both in the United States and worldwide. In the European and Pacific CRS
markets, various consortia of foreign carriers have formed CRSs to be marketed
in countries in which the owning carriers have a substantial presence.
 
 Government Regulation
 
 
  General. All carriers engaged in air transportation in the United States,
including United, are subject to regulation by the DOT and the FAA under the
Federal Aviation Act of 1958, as amended (the "Aviation
 
                                       8
<PAGE>
 
Act"). The DOT has authority to regulate certain economic and consumer
protection aspects of air transportation. It is empowered to issue certificates
of public convenience and necessity for domestic air transportation upon a
carrier's showing of fitness; to prohibit unjust discrimination; to prescribe
forms of accounts and require reports from air carriers; to regulate methods of
competition, including the provision and use of computerized reservation
systems; and to administer regulations providing for consumer protection,
including regulations governing the accessibility of air transportation
facilities for handicapped individuals. United's operations require
certificates of public convenience and necessity issued by the DOT, an air
carrier operating certificate and related operations specifications issued by
the FAA.
 
  United's operations also require licenses issued by the aviation authorities
of the foreign countries United serves. Foreign aviation authorities may from
time to time impose a greater degree of economic regulation than exists with
respect to United domestic operations.
 
  In international markets, United competes against foreign investor-owned and
national flag carriers and U.S. carriers that have been granted authority to
provide scheduled passenger and freight service between points in the United
States and various overseas destinations. In connection with its international
services, United is required to file with the DOT and observe tariffs
establishing the fares and rates charged and the rules governing the
transportation provided. In addition, United's operating authorities in
international markets are governed by the aviation agreements between the
United States and foreign countries.
 
  In certain cases, fares, rates and schedules require the approval of the DOT
and the relevant foreign governments. United has recommended to the U.S.
Congress that it consider developing an international aviation policy that
seeks enhanced access to international markets for U.S. carriers in return for
access to U.S. markets by foreign carriers. Shifts in United States or foreign
government aviation policies can lead to the alteration or termination of
existing air service agreements that the U.S. has with other governments, which
could diminish the value of United's international routes. For example, in 1993
the DOT determined that the Government of Japan violated its aviation agreement
with the U.S. when it prevented United from implementing service between Tokyo
and Sydney as part of United's New York-Tokyo-Sydney schedule. The DOT is
considering various actions against Japan. While such disputes are generally
the subject of inter- governmental negotiations, there are no assurances that
United's operating rights under the bilateral aviation agreements and DOT-
issued certificates of public convenience and necessity can be preserved in
such cases.
 
  The DOT and the U.S. Congress have engaged from time to time in various
regulatory and legislative initiatives, respectively, with respect to CRS
activities and issues, such as the level of booking fees, host versus non-host
functionality, mandatory dehosting, travel agency connection of third-party
hardware and software to a CRS, terms of the contracts between CRS vendors and
travel agencies, continued airline ownership of CRS vendors, and the ability to
access multiple CRS systems from a single computer terminal. New regulatory or
legislative initiatives in many of these areas, if enacted, could have a
material adverse effect upon CRS vendors in general and ATS and United in
particular.
 
  Safety. The FAA has regulatory jurisdiction over flight operations generally,
including equipment, ground facilities, maintenance, communications and other
matters. In order to ensure compliance with its operational and safety
standards, the FAA requires air carriers to obtain operating, airworthiness and
other certificates.
 
  United's aircraft and engines are maintained in accordance with the standards
and procedures recommended and approved by the manufacturers and the FAA. For
all of its engines, United utilizes a "condition monitoring" maintenance
program so that the schedule for engine removals and overhauls is based on
performance trend monitoring of engine operating data. In addition, all engines
contain time-limited components, each of which has a maximum amount of time
(measured by operating hours) or a maximum number of operating cycles (measured
by takeoffs and landings) after which the component must be removed from the
engine assembly and overhauled or scrapped. Similarly, United's FAA-approved
maintenance program specifies the number of hours or operating cycles between
inspections and overhauls of the airframes
 
                                       9
<PAGE>
 
and their component parts. The nature and extent of each inspection and
overhaul is specifically prescribed by the approved maintenance program.
 
  From time to time, the FAA issues airworthiness directives ("ADs") which
require air carriers to undertake inspections and to make unscheduled
modifications and improvements on aircraft, engines and related components and
parts. The ADs sometimes cause United to incur substantial, unplanned expense
and occasionally aircraft or engines must be removed from service prematurely
in order to undergo mandated inspections or modifications on an accelerated
basis. The issuance of any particular AD may have a greater or lesser impact on
United compared to its competitors depending upon the equipment covered by the
directive.
 
  Since 1988 the airlines, in cooperation with the FAA, have been engaged in an
in-depth review of the adequacy of existing maintenance procedures applicable
to older versions of most of the aircraft types in general use in the airline
industry. These include certain of the Boeing and Douglas aircraft used by
United. As a part of this program, the FAA has issued ADs requiring interim
inspections and remedial maintenance procedures. While certain of these aging
aircraft ADs have necessitated unscheduled removals from service and increased
maintenance costs, compliance is not expected to have a material adverse impact
on United's costs or operations.
 
  Legislation enacted by the U.S. Congress required the installation, in all
types of aircraft operated by United, of a traffic collision avoidance system
(TCAS) by November 30, 1993, and a windshear detection system by December 30,
1993. United completed the installations of both systems prior to their
respective mandated deadline dates on all aircraft operated by it.
 
  Both the DOT and the FAA have authority to institute administrative and
judicial proceedings to enforce the Aviation Act and their own regulations,
rules and orders. Both civil and criminal sanctions may be assessed for
violations. The Aviation Act provides for the assessment of civil penalties in
amounts of up to $10,000 per violation which are applicable to most cases
involving the safety of commercial aircraft operations, including the airport
security responsibilities of air carriers.
 
  Environmental Regulations. The Airport Noise and Capacity Act of 1990
("ANCA") requires the phase-out by December 31, 1999 of Stage 2 aircraft
operations, subject to certain waivers. The FAA has issued final regulations
which would require carriers to modify or reduce the number of Stage 2 aircraft
operated by 25% by December 31, 1994, 50% by December 31, 1996, 75% by December
31, 1998 and 100% by December 31, 1999. Alternatively, a carrier could satisfy
compliance requirements by operating a fleet that is at least 55% Stage 3 by
December 31, 1994, 65% Stage 3 by December 31, 1996, 75% Stage 3 by December
31, 1998 and 100% Stage 3 by December 31, 1999. At December 31, 1993, United
operated 371 Stage 3 aircraft representing 70% of United's total fleet, and
thus is in compliance with these regulations.
 
  The ANCA recognizes the rights of operators of airports with noise problems
to implement local noise abatement procedures so long as such procedures do not
interfere unreasonably with interstate or foreign commerce or the national air
transportation system. ANCA generally requires FAA approval of local noise
restrictions on Stage 3 aircraft first effective after October 1990, and
establishes a regulatory notice and review process for local restrictions on
Stage 2 aircraft first proposed after October 1990. While United has had
sufficient scheduling flexibility to accommodate local noise restrictions
imposed to the present, United's operations could be adversely affected if
locally-imposed regulations become more restrictive or widespread.
 
  Federal Aviation Regulation Part 150, which was issued pursuant to Title I of
the Aviation Safety and Noise Abatement Act of 1979, provides limited funding
to airport operators to formulate noise compatibility programs, and established
procedures through which such programs may be approved by the FAA. This rule
may encourage the consideration of additional local aircraft and airport usage
restrictions.
 
  The Environmental Protection Agency regulates operations, including air
carrier operations, which affect the quality of air in the United States.
United has made all necessary modifications to its operating fleet to meet
emission standards issued by the Environmental Protection Agency ("EPA").
 
                                       10

  Federal and state environmental laws require that underground storage tanks
(USTs) be upgraded to new construction standards and equipped with leak
detection by December 22, 1998. These requirements are phased into effect based
on the age, construction and use of existing tanks. United operates a number of
underground and above ground storage tanks throughout its system, primarily
used for the storage of fuels and deicing fluids. A program for the removal or
upgrading of USTs and remediation of any related contamination has been ongoing
since 1987. Compliance with these federal and state UST regulations is not
expected to have a material adverse effect on United's financial condition.
 
  United has been identified by the EPA as a potentially responsible party with
respect to Superfund sites involving soil and groundwater contamination at the
Bay Area Drum Site in San Francisco, California, the Chemsol, Inc. Site in
Piscataway, New Jersey, the Petrochem/Ekotek Site in Salt Lake City, Utah, the
Monterey Park Site at Monterey Park, California, the West Contra Costa Sanitary
Landfill Site in Richmond, California, and the Douglasville Site in Berks
County, Pennsylvania. Because of the limited nature of the volume of pollutants
allegedly contributed by United to the above Superfund sites, the outcome of
these matters is not expected to have a material adverse effect on United's
financial condition.
 
  United is aware of soil and groundwater contamination present on its
leaseholds at several U.S. airports, with the most significant locations being
San Francisco International Airport, Kennedy, Seattle Tacoma International
Airport, Spokane International Airport, and Stapleton International Airport in
Denver (which is expected to close in the Spring of 1994 due to the opening of
a new airport for Denver). United is investigating these sites, assessing its
obligations under applicable environmental regulations and lease agreements,
and where appropriate remediating these sites. Remediation of these sites, for
which United may be responsible, is not expected to have a material adverse
effect on United's financial condition.
 
  Other Government Matters. Besides the DOT and the FAA, other federal agencies
with jurisdiction over certain aspects of United's operations are the
Department of Justice (Antitrust Division and Immigration and Naturalization
Service), the Equal Employment Opportunity Commission, the Occupational Safety
and Health Administration, the Department of Labor (the Office of Federal
Contract Compliance Programs of the Employment Standards Administration), the
National Labor Relations Board, the National Mediation Board, the National
Transportation Safety Board, the Treasury Department (U.S. Customs Service),
the Federal Communications Commission (due to use of radio facilities by
aircraft), and the United States Postal Service (carriage of domestic mail). In
connection with its service to cities in other countries, United is subject to
varying degrees of regulation by foreign governments. United has no existing
obligation to the Civil Reserve Air Fleet.
 
 Fuel
 
  United's results of operations are significantly affected by the price and
availability of jet fuel. Based on 1993 fuel consumption, every $.01 change in
the average annual price-per-gallon of jet fuel caused a change of
approximately $27 million in United's annual fuel costs. The table below shows
United's fuel expenses, fuel consumption, average price per gallon and fuel as
a percent of total operating expenses for annual periods from 1989 through
1993:
 
<TABLE>

% of total operating expenses..........     12%     13%     14%     16%     15%
</TABLE>
 
  United's average fuel cost per gallon in 1993 was 4.2% lower than in 1992.
Changes in fuel prices are industry-wide occurrences that benefit or harm
United's competitors as well as United. Accordingly, lower fuel prices may be
offset by increased price competition and lower revenues for all air carriers,
including United. There can be no assurance that United will be able to
increase its fares in response to any increases in fuel prices in the future.
 
                                       11
<PAGE>
 
  In order to assure adequate supplies of fuel and to provide a measure of
control over fuel costs, United continues to ship fuel on major pipelines,
maintains fuel storage facilities, and trades fuel to locations where it is
needed. In 1993, almost all of United's fuel was purchased under contracts with
major U.S. and international oil companies. Most of these contracts are
terminable by either party on short notice. United also purchases minor volumes
of fuel on the spot market at some domestic locations. In addition, United
purchases foreign fuel on a spot basis from the Middle East, Caribbean and Far
East. Although United has not experienced any problem with fuel availability in
the past few years and does not anticipate any in the near future, it is
impossible to predict the future availability of jet fuel. If there were major
reductions in the availability of jet fuel, United's business would be
adversely affected.
 
 Insurance
 
  United carries liability insurance of a type customary in the air
transportation industry, in amounts which it deems adequate, covering passenger
liability, public liability and property damage liability. Insurance is subject
to price fluctuations from time to time. The amount recoverable by United under
aircraft hull insurance covering all damage to its aircraft is not subject to
any deductible amount in the event of a total loss. In the event of a partial
loss, however, such recovery is subject to a per-occurrence deductible of
$1,000,000 for B747s, B757s, B767s and DC10s, $750,000 for B737-300s, and B737-
500s, and $500,000 for all other aircraft except commuter aircraft, for which
the deductible is $100,000.
 
 Employees--Labor Matters
 
  On December 31, 1993, United had 81,511 employees (approximately ten percent
of whom are part-time employees). Approximately 64% of United's employees were
represented by various labor organizations.
 
  The employee groups, number of employees, labor organization and current
contract status for each of United's major collective bargaining groups as of
December 31, 1993 are as follows:

 * The flight kitchen sales (see Item 2, Properties, "Transfers of Assets")
   occurring in 1994 are expected to reduce United's number of total employees
   by more than 4,000 from December 31, 1993 levels.
** If the proposed Employee Investment Transaction is consummated, the IAM and
   the ALPA contracts each will not be open for amendment until the year 1999
   or 2000, depending on when the transaction closes and whether the AFA
   participates in the transaction.
 
  United's relations with these labor organizations are governed by the Railway
Labor Act. Under this Act, collective bargaining agreements between United and
these organizations become amendable upon the expiration of their stated term.
If either party wishes to modify the terms of any such agreement, it must
notify the other party before the contract becomes amendable. After receipt of
such notice, the parties must meet for direct negotiations and, if no agreement
is reached, either party may request that a mediator be appointed. If no
agreement is reached, the National Mediation Board may determine, at any time,
that an impasse exists and may proffer arbitration. Either party may decline to
submit to arbitration. If arbitration is rejected, a 30-day "cooling off"
period commences, following which the labor organization may strike and the
airline may resort to "self-help," including the imposition of its proposed
amendments and the hiring of replacement workers.
 
  United's wage and related costs accounted for 33% of its total operating
expenses for the twelve months ended December 31, 1993. In order to enhance its
competitive position, United has taken various steps to reduce its unit costs,
including the layoffs of 2,800 employees in February 1993, the reduction in
force which is resulting from the flight kitchen sales, reductions in non-
personnel expenses and the redeployment of certain aircraft to more profitable
airports.
 
                                       12

  The long-term competitiveness of United's labor costs, and the long-term
financial stability and profitability of United, is expected to be improved if
the proposed Employee Investment Transaction is consummated.

* United' s aircraft leases have initial terms of 4 to 26 years, and expiration
  dates range from 1994 through 2018. Under the terms of leases for 287 of the
  aircraft in the operating fleet, United has the right to purchase the
  aircraft at the end of the lease term, in some cases at fair market value and
  in others at fair market value or a percentage of cost.
 
  As of December 31, 1993, 78 of the 246 aircraft owned by United were
encumbered under transaction agreements.
 
  In 1993 United took delivery of 43 new aircraft. United acquired ten B737-
500s, four B747-400s, 16 B757-200s, eight B767-300ERs, and five A320-200s.
 
  In early 1993, United revised its capital spending plan based on reductions
in its capacity requirements for the next several years. Consistent with this
reduced capital spending plan, United reached agreement with Boeing to convert
49 firm aircraft orders into options, and to delay delivery of certain aircraft
originally scheduled for delivery between 1993 and 1996 into the 1996-1999
period. Under the terms of the agreement, if United does not elect to confirm
the delivery of these option aircraft, it will forfeit significant deposits.
United also reached agreement with Airbus to delay delivery of 14 A320s
originally scheduled for delivery after 1994. In addition, United announced in
1993 that it would accelerate the retirement of 25 widebody aircraft, including
15 DC10-10s and ten B747-SPs, retiring them prior to the end of 1994; six of
these 25 widebody aircraft (five DC10-10s and one B747-SP) were retired in
1993.
 
  As a result of these new agreements, as of December 31, 1993, United had
taken delivery of all aircraft on order, with the exception of 34 B777-200
aircraft, which are scheduled to be delivered between 1995 and 1999. In
addition to the B777-200 order, United has arrangements with Airbus and A320
engine

manufacturer International Aero Engines to lease an additional 45 A320-200
aircraft, which are scheduled for delivery through 1998. At December 31, 1993,
United also had purchase options for 186 B737 aircraft, 54 B757-200 aircraft,
34 B777-200 aircraft, 52 B747-400 aircraft, 8 B767-300ER aircraft and 50 A320-
200.
 
  In January 1994, United entered into an agreement with Boeing to acquire two
new B747-400 aircraft in 1994, in place of options for two similar aircraft.
These two aircraft orders fulfill part of United's obligation to Boeing under
the 1993 restructuring agreement described above.
 
  The following table sets forth United's firm aircraft orders, options and
expected delivery schedules as of December 31, 1993:

  * In addition, United has agreed to lease an additional 45 A320-200
    aircraft. Deliveries of these aircraft are expected to occur between 1994
    and 1998. Also, in January 1994, United entered into an agreement with
    Boeing to acquire two new B747-400 aircraft in 1994, in place of options
    for two similar aircraft.

  Ground Facilities
 
  In the vicinity of O'Hare, United owns a 106 acre complex consisting of over
one million square feet of office space for its executive headquarters, a
computer facility, and a training center. United operates reservation centers
in or near eight U.S. cities--Chicago, Denver, Detroit, Honolulu, Los Angeles,
San Francisco, Seattle and Washington, D.C. United also operates 133 city
ticket offices in the U.S., plus offices in the Pacific and European countries
served by United.
 
  United's Maintenance Operation Center ("MOC") at San Francisco International
Airport occupies 144 acres of land, three million square feet of floor space
and 12 aircraft hangar docks, under leases expiring in 2013. Virtually all
major aircraft and component maintenance for United's fleet occurs at the MOC,
including aircraft acceptance and flight testing, and the installation,
testing and repairing of engines, electronics, and interior fittings. United
also has a major facility at the Oakland, California airport which is
dedicated to airframe maintenance and which includes a hangar with sufficient
space to accommodate maintenance work on four wide-bodied aircraft
simultaneously. As of December 31, 1993, United employed more than 11,970
mechanics, inspectors, engineers, and maintenance support personnel at the MOC
and over 1,660 at the Oakland facility. United also has line aircraft
maintenance employees and facilities at 36 domestic and 18 international
locations.
 
  In March 1994, United opened a new major aircraft maintenance and overhaul
facility ("MOC-II") in Indianapolis. Operating under a lease with the
Indianapolis Airport Authority which expires November 30, 2031. When all
phases of the construction work are completed, as scheduled, in 2004, United
will employ 6,300 people at MOC-II, and will occupy approximately 300 acres of
land and up to three million square feet of space, including 15 aircraft dock
positions. MOC-II will be used for maintenance of Boeing 737 aircraft, engine
repair, spare parts storage, ground equipment maintenance, technical support
and administrative functions.

  In Spring 1994 United expects to relocate its Denver hub operations to the
new Denver International Airport. Under a new 30-year lease and use agreement,
expiring in 2023, United eventually will occupy 44 gates and over one million
square feet of exclusive terminal building space. The new airport is located
northeast of Stapleton International Airport and approximately 25 miles from
downtown Denver. Upon the opening of the new airport, Stapleton will be closed
to all aircraft operations. United's flight training center will continue to be
located near Stapleton and is under lease, including options to extend, until
2018. This flight training center consists of four buildings with a total of
300,000 square feet located on 22 acres of land adjoining Stapleton. The flight
training center accommodates 26 flight simulators and over 90 computer-based
training stations, as well as cockpit procedures trainers, autoflight system
trainers and emergency evacuation trainers.
 
  United has entered into various leases relating to its use of airport landing
areas, gates, hangar sites, terminal buildings and other airport facilities in
most of the municipalities it serves. In many cases United has constructed, at
its expense, the buildings it occupies on its leased properties. In general,
buildings and fixtures constructed by United on leased land are the property of
the lessor upon the expiration of such leases. United also has leased and
improved ticketing, sales and general office space in the downtown and outlying
areas of most of the larger cities in its system. United believes its
facilities are suitable and adequate for its current requirements. United will
continue to acquire equipment and facilities as necessary to support its
airline operations.
 
 Transfers of Assets
 
  In third quarter of 1993, United reached agreements to sell, lease or
otherwise transfer assets related to the operation of 16 of its 17 domestic
flight kitchens to Dobbs International services, Inc. and Caterair
International Corp. for $119 million in a series of phased closings that
commenced in December 1993 and are expected scheduled to continue through mid-
1994. Under the agreements, the purchasers will provide catering services for
United at the airports served by the flight kitchens for seven years.
 
ITEM 3. LEGAL PROCEEDINGS
 
  The Company is involved from time to time in legal proceedings incidental to
the ordinary course of its business. Such proceedings include claims brought by
and against the Company or its subsidiaries including claims seeking
substantial compensatory and punitive damages. Such claims arise from routine
commercial disputes as well as incidents resulting in bodily injury and damage
to property. The Company believes that the potential liabilities in all of
bodily injury and property damage actions are adequately insured and none of
the other actions are expected to have any material adverse effect on the
Company or its subsidiaries.
 
 Noise Proceedings
 
  United may be affected by legal proceedings brought by owners of property
located near certain airports. Plaintiffs generally seek to enjoin certain
aircraft operations and/or to obtain damages against airport operators and air
carriers as a result of alleged aircraft noise or air pollution. Any liability
or injunctive relief imposed against airport operations or air carriers could
result in higher costs to United and other air carriers.
 
  The ultimate disposition of the matters discussed in Item 3 hereof, and other
claims affecting the Company, are not expected to have a material adverse
effect on the Company's financial condition.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On December 22, 1993, the Board of Directors of UAL Corporation ("UAL"),
parent company of United Air Lines, Inc. ("United"), approved a non-binding
agreement in principle that would provide a majority equity interest in UAL to
the employees of United in exchange for wage concessions and work-rule changes.
In January 1994, the agreement was ratified by the Air Line Pilots Association
("ALPA") and the International Association of Machinists ("IAM"). The
transaction is subject to, among other things, approval by UAL stockholders.
 
  The employee investment plan is intended to put in place a lower cost
structure that allows United to compete effectively in the aviation marketplace
and address its long-term financial viability. The concessions will come from
three of United's employee groups: employees represented by ALPA, employees
represented by the IAM and the salaried and management employees. Employees
represented by the Association of Flight Attendants ("AFA") have been invited
to participate in the plan and UAL has engaged in discussions with the AFA
concerning such participation.
 
  In the transaction, an Employee Stock Ownership Plan will be created to
provide United employees with a minimum of a 53% equity interest in UAL in
exchange for wage concessions and work-rule changes. The employee interest may
increase to up to 63%, depending on the average market value of UAL common
stock in the year after the transaction closes. The transaction is not
dependent on external financing.
 
  Pursuant to the terms of the agreement in principle, current UAL stockholders
would receive the remaining 37 to 47% of the common stock and $88 per share in
cash and face amount of debt and preferred stock. The non-common stock
consideration is expected to aggregate approximately $743 million of cash, $900
million face amount of senior unsecured debentures and $900 million face amount
of preferred stock depending on the number of common shares on which the
distribution is made. While the agreement in principle contemplates that the
debentures would be issued by UAL, such debentures could be issued by United.
 
  The agreement includes terms for the creation of a low-cost short-haul
operation to compete in domestic markets. This short-haul operation, in
combination with the other wage and work-rule concessions, is expected to
increase United's cash flows from operating activities.
 
  UAL agreed that if the transaction closes prior to August 31, 1994, severance
payments and employee benefits coverage approximating $50 million would be
provided by United to IAM employees being terminated from United as a result of
the recent sale of flight kitchens (see Sale of Flight Kitchens), in addition
 
                                       16
<PAGE>
 
to payments required under United's labor contracts. Certain of the severance
payments, which are to be made on a monthly basis, became payable in January
1994 after the unions ratified the agreement; however, these monthly payments
terminate but are not refunded if the transaction does not close before August
31, 1994 or certain other conditions are not met. Other lump-sum severance
amounts are payable only if the transaction closes prior to the required date.
UAL has also agreed to pay up to $45 million of transaction fees and expenses
incurred by ALPA and the IAM if the transaction is closed by August 31, 1994.
If the transaction does not close by the required date but certain conditions
are met, UAL will pay up to $12.5 million of ALPA and IAM transaction expenses.
 
  Under the terms of the agreement in principle, United may not, among other
things, incur incremental debt or other obligations, or sell certain assets,
other than in the ordinary course of business, prior to the consummation of the
transaction. In addition, after consummation of the transaction, certain
activities, including certain asset dispositions, may require a different
approval process by the UAL Board of Directors, and in some cases the
shareholders, than is currently required.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During 1993, United's total cash, cash equivalents and short-term investments
decreased $266 million to a balance of $966 million at December 31, 1993.
Operating activities generated $818 million. Cash was used primarily to repay
long-term debt, reduce short-term borrowings and to fund net additions to
property and equipment.
 
  Repayments of long-term debt amounted to $664 million, including the early
extinguishment of $500 million of senior subordinated notes in June 1993. In
addition, $55 million was used for capital lease payments during the period.
Long-term debt and capital lease obligations incurred in connection with
aircraft financings during 1993 amounted to $557 million. As a result of the
year's financing activities, United's debt:equity ratio was 85:15 at December
31, 1993, unchanged from December 31, 1992.
 
  During 1993, United placed 43 new aircraft in service. These aircraft were
financed primarily with long-term debt, capital leases and operating leases.
United acquired 10 B737-500 aircraft, 16 B757-200 aircraft, four B747-400
aircraft, eight B767-300ER aircraft and five A320-200 aircraft during 1993. Of
these, 16 aircraft were purchased, 18 were purchased and then sold and leased
back, seven were acquired under operating leases and two were acquired in
capital lease transactions. Aircraft purchases and other property additions,
including aircraft modification projects and aircraft spare parts, amounted to
$1.484 billion. Property dispositions, which included sale and leaseback
transactions and the sales of five B727 aircraft, provided $1.156 billion.
 
  In early 1993, United revised its capital spending plan based on reductions
in its capacity requirements for the next several years. United reached
agreement with The Boeing Company ("Boeing") to convert certain aircraft orders
into options. Under the terms of the agreement, if United does not elect to
confirm the delivery of these option aircraft before 1998, it will forfeit
significant deposits. United also announced an agreement with Airbus Industrie
("Airbus") to delay from 1995 and 1996 to 1997 and 1998 delivery of 14 leased
A320 aircraft. In addition, United announced that it would accelerate the
retirement of 25 widebody aircraft, including 15 DC10-10s and ten B747-SPs,
retiring them prior to the end of 1994. In 1993, United recorded a $59 million
charge to reduce the net book value of the DC-10 aircraft to estimated net
realizable value.
 
  As a result of these new agreements, as of December 31, 1993, United had
taken delivery of all aircraft on order, with the exception of 34 B777
aircraft, which are expected to be delivered between 1995 and 1999. In addition
to the B777 order, United has arrangements with Airbus and International Aero
Engines to lease an additional 45 A320 aircraft, which are scheduled for
delivery through 1998. At December 31, 1993, United also had options for 186
B737 aircraft, 54 B757 aircraft, 34 B777 aircraft, 52 B747 aircraft, eight B767
aircraft and 50 A320 aircraft. In January 1994, United entered into an
agreement with Boeing to acquire two B747-400 aircraft in 1994 in place of
options for two similar aircraft. United continually reviews its fleet to
determine whether aircraft acquisitions will be used to expand the fleet or to
replace older aircraft, depending on market and regulatory conditions at the
time of delivery.
 
                                       17
<PAGE>
 
  Commitments for the purchase of aircraft and other property at December 31,
1993 approximated $4.3 billion, after deducting advance payments. An estimated
$0.6 billion will be spent in 1994, $1.1 billion in 1995, $0.8 billion in 1996,
$1.2 billion in 1997, $0.4 billion in 1998, and $0.2 billion after 1998. These
amounts do not include the two B747-400 aircraft to be acquired under the
January 1994 agreement referred to above.
 
  Funds necessary to finance aircraft acquisitions are expected to be obtained
from internally generated funds, irrevocable external financing arrangements or
other external sources. In 1993, UAL and United filed a shelf registration
statement with the Securities and Exchange Commission for up to $1.5 billion of
securities, including secured and unsecured debt, equipment trust certificates,
equity or a combination of both. Under the terms of this shelf registration
statement, a 1992 shelf and a 1991 shelf were combined with the 1993 shelf
statement. In December 1993, United issued $100 million of debentures under the
shelf registration statement. In May and November 1993, United issued $176
million and $118 million, respectively, of pass through certificates under the
shelf registration to refinance aircraft under operating leases. On a combined
basis, up to $1.776 billion of additional securities may be offered at December
31, 1993. The shelf registration statement may be utilized for purposes of
registering securities to be issued in the employee investment transaction.
 
  United's senior unsecured debt is rated BB by Standard & Poor's Corporation
("S & P") and Baa3 by Moody's Investors Service Inc. ("Moody's"). These ratings
reflect an October 1993 downgrade by Moody's. On December 17, 1993, Moody's
announced that it was placing United's securities under review for possible
downgrade citing reports about the potential for the employee investment
transaction. On December 20, 1993, S & P announced that it was placing the
securities on CreditWatch with developing implications, meaning the ratings may
be raised or lowered.
 
  United is in the process of constructing a maintenance facility in
Indianapolis, which begins operation in 1994. The facility is being financed
primarily with tax-exempt bonds and other capital sources.
 
  As of December 31, 1993, United had a working capital deficit of $1.608
billion. Historically, United has operated with a working capital deficit and,
as in the past, United expects to meet all of its obligations as they become
due.
 
  Operating and financing activities in 1992 generated cash flows of $287
million and $127 million, respectively, which more than offset cash used for
net additions to property, resulting in a $96 million increase in cash, cash
equivalents and short-term investments. During the year, $2.458 billion was
spent on property additions, principally aircraft. United acquired 25 B737-500
aircraft, 25 B757-200 aircraft, 10 B767-300ER aircraft and six B747-400
aircraft in 1992. Of these, 18 aircraft were purchased, 38 were purchased and
then sold and leased back and 10 were acquired in capital lease transactions.
Property dispositions provided cash proceeds of $2.363 billion. In 1992, United
also acquired certain Latin American route authorities and other related assets
from Pan American World Airways, Inc. ("Pan Am").
 
  During 1991, operating property additions amounted to $2.122 billion and
included the acquisition of 23 B757-200 aircraft, 18 B737-500 aircraft, five
B767-300ER aircraft, four B747-400 aircraft and seven used B747-200 aircraft.
Dispositions of property, including the sale and leaseback of 15 aircraft and
the sales of two DC8-71 aircraft and four B727-100 aircraft, provided $1.281
billion. United also acquired international route authorities and other assets
from Pan Am, which was the primary cause of a $358 million increase in
intangibles. However, cash provided by operating activities of $355 million and
financing activities of $827 million allowed United to maintain a relatively
stable balance of cash, cash equivalents and short-term investments, which
amounted to $1.136 billion at December 31, 1991.
 
RESULTS OF OPERATIONS
 
  United's results of operations in 1993 improved considerably as compared to
1992. In 1993, United recorded a net loss of $36 million, compared to a 1992
net loss of $933 million. The 1993 results include an
 
                                       18
<PAGE>
 
extraordinary loss of $19 million on the early extinguishment of debt. The 1992
results include a $547 million cumulative effect of adopting Statement of
Financial Accounting Standard ("SFAS") No. 106, "Employers' Accounting for
Postretirement Benefits Other than Pensions" and SFAS No. 109, "Accounting for
Income Taxes." The 1993 loss before extraordinary item was $17 million,
compared to a 1992 loss before cumulative effect of accounting changes of $386
million.
 
  United recorded operating earnings in 1993 of $295 million compared to an
operating loss in 1992 of $496 million. The improved performance in 1993 was
benefitted by the cost reduction program implemented in 1993, the realignment
of domestic schedules to eliminate unprofitable routes in an effort to enhance
revenue performance and the impact of a labor union strike on a competing air
carrier. United's 1992 losses were significantly affected by uneconomic fare
actions initiated by other carriers that increased traffic and load factors to
unprecedented levels, but resulted in substantially reduced yield (passenger
revenue per revenue passenger mile).
 
  While United's results showed improvement in 1993, the results of operations
in the airline business can fluctuate significantly in response to general
economic conditions. This is because small fluctuations in yield and cost per
available seat mile can have a significant effect on operating results. Thus,
United believes that industrywide fare levels, increasing low-cost competition,
prolonged operations of carriers under bankruptcy protection, general economic
conditions, fuel costs, international governmental policies and other factors
over which it has limited control, will continue to affect its operating
results.
 
  In addition, United expects its 1994 operating results to be impacted by
increases in operating expenses of approximately $100 million related to
operations at the new Denver International Airport, and approximately $70
million related to employee pension costs as a result of lowering the assumed
discount rate from 8.75% to 7.5%.
 
1993 COMPARED WITH 1992
 
  Operating Revenues.  Operating revenues increased $1.629 billion (13%).
Passenger revenues increased $1.353 billion (12%) due to a 9% increase in
revenue passenger miles and a 2% increase in yield to 12.48 cents. Domestic
revenue passenger miles increased 6% on an increase of 8% in domestic available
seat miles, resulting in a decrease of 1.0 point in domestic passenger load
factor to 65.2%. International revenue passenger miles increased 14%. Passenger
traffic increased in substantially all international markets, especially in
Latin America, where United began service in the first quarter of 1992.
Passenger load factors increased in Latin America, the Atlantic and the
Pacific. On a system basis, available seat miles increased 10% and passenger
load factor decreased 0.2 points to 67.2%.
 
  Cargo revenues increased $167 million (21%), due to increases of $144 million
in freight revenues and $23 million in mail revenues. The freight revenue
increase reflects both volume and unit revenue increases largely attributable
to increased international operations. Contract services and other revenues
increased $109 million (18%) primarily as a result of revenues generated by
Apollo Travel Services Partnership ("ATS"), a consolidated general partnership
77% owned by United, that was formed by the 1993 merger of two affiliates of
United. (see Note 3 of the Notes to Consolidated Financial Statements)
 
  Operating Expenses.  Operating expenses increased $838 million (6%). United's
cost per available seat mile decreased 3% to 9.33 cents. The decrease in unit
cost was largely due to the implementation of a cost reduction program in early
1993. Commissions increased $288 million (13%) due to increased revenues and
slightly higher cargo commission rates. Salaries and related costs increased
$208 million (5%) primarily due to higher average wage rates and higher costs
associated with pensions and health insurance. Rentals and landing fees
increased $169 million (13%) primarily reflecting rent associated with a larger
number of aircraft on operating leases. Aircraft maintenance increased $60
million (20%) due principally to higher outside maintenance costs. Purchased
services increased $48 million (5%) due principally to higher computer
reservations fees and higher costs associated with international operations,
such as communications,
 
                                       19
<PAGE>
 
navigation charges and security. Depreciation and amortization increased $27
million (4%) due principally to newly acquired aircraft. Aircraft fuel expense
increased $39 million, as a 7% increase in fuel consumption was partially
offset by a 4% decrease in the average price per gallon of fuel to 63.6 cents.
Other operating expenses increased $80 million (10%) due principally to the
consolidation of ATS after the merger. Advertising and promotion decreased $51
million (24%) and food and beverages decreased $24 million (7%) due to cost
reduction efforts.
 
  Other Income and Expense.  Other expense amounted to $321 million in 1993
compared to $106 million in 1992. Interest expense increased $31 million due
primarily to increased debt and capital lease obligations incurred in
connection with aircraft financings. Interest capitalized decreased $41 million
(45%) due to lower advance payments on new aircraft. United's equity in the
results of affiliates shifted from income of $42 million in 1992, representing
United's share of Covia Partnership ("Covia") earnings, to losses of $30
million in 1993, primarily due to a charge recorded by Galileo International
for the cost of eliminating duplicate facilities and operations after the
merger of Covia and the Galileo Company. Included in "Miscellaneous, net" were
foreign exchange losses of $20 million in 1993 compared to gains of $2 million
in 1992. Also included in 1993 was a charge of $59 million to reduce the net
book value of 15 DC-10 aircraft to estimated net realizable value and a $17
million gain resulting from the final settlement for overpayment of annuities
purchased in 1985 to cover certain vested pension benefits. Interest income
increased $11 million due principally to interest received in connection with
the same settlement. In 1992, "Miscellaneous, net" also included gains on
disposition of property of $32 million, a charge of $13 million to record the
cash settlement of class action claims resulting from litigation relating to
the use of airline fare data.
 
1992 COMPARED WITH 1991
 
  In 1992, United recorded a net loss of $933 million, compared to the 1991 net
loss of $335 million. The 1992 loss before the cumulative effect of adoption of
SFAS No. 106 and SFAS No. 109 was $386 million.
 
  Operating Revenues. Operating revenues increased $1.065 billion (9%).
Passenger revenues increased $1.033 billion (10%) due to a 13% increase in
revenue passenger miles partially offset by a 2% decrease in yield to 12.19
cents. The increase in passenger traffic was largely attributable to United's
international operations. European operations increased significantly with the
April 1991 acquisition of route authorities from Pan Am. Latin American
operations began in January 1992 as United started serving certain former Pan
Am destinations. Pacific air travel demand also improved compared to 1991,
which was adversely impacted by the Gulf war. Domestic traffic increased
primarily as a result of fare reductions initiated by other carriers. Domestic
revenue passenger miles increased 5% and available seat miles increased 2%,
resulting in a 2.0 point increase in domestic load factor to 66.2%. On a system
basis, United's revenue passenger miles increased 13% and available seat miles
increased 11%, resulting in a 1.1 point increase in passenger load factor to
67.4%.
 
  Cargo revenues increased $89 million (13%), primarily due to increased
freight revenues, reflecting both volume and unit revenue increases as a result
of expanded international operations. Contract services and other revenues
decreased $57 million (9%) primarily as a result of a decrease in fuel sales.
 
  Operating Expenses. Operating expenses increased $1.070 billion (9%).
United's cost per available seat mile decreased 2% to 9.6 cents. Salaries and
related costs increased $430 million (11%) primarily due to increased flight
crew and customer service personnel, higher average wage rates and higher costs
associated with pensions and health insurance. The increase in salaries and
related costs included $75 million related to SFAS No. 106, which was adopted
effective January 1, 1992. Rentals and landing fees increased $212 million
(20%) reflecting rent associated with an increasing number of aircraft on
operating leases and higher airport facilities rent and landing fees, primarily
related to international operations. Commissions increased $166 million (8%)
due to increased revenues, as average commission rates remained relatively
unchanged. Purchased services increased $142 million (18%) due principally to
higher computer reservations fees and higher costs associated with
international operations, such as communications, navigation charges and
 
                                       20
<PAGE>
 
security. Depreciation and amortization increased $91 million (15%) due
principally to newly acquired aircraft. Food and beverages increased $49
million (17%) due to a higher per passenger cost, reflecting a passenger mix
more heavily weighted by international passengers. Aircraft fuel expense
increased $5 million, as an 8% increase United's in fuel consumption was
partially offset by a 7% decrease in the average price per gallon of fuel to
66.4 cents. Aircraft maintenance decreased $57 million (16%) due principally to
lower outside maintenance costs and the retirement of the B727-100 fleet. Other
operating expenses decreased $2 million due to selling less fuel to third
parties.
 
  Other Income and Expense. Other expense amounted to $106 million in 1992
compared to $22 million in 1991. Interest expense increased $106 million due
primarily to increased debt and capital lease obligations incurred in
connection with 1991 and 1992 aircraft financings. Interest income decreased
$19 million due to lower interest rates. Equity in the earnings of affiliates
increased $35 million as a result of higher Covia booking revenues and the
settlement of certain partner accounts in 1991. "Other income (expense)--
Miscellaneous, net" included foreign exchange gains of $2 million in 1992
compared to losses of $20 million in 1991. Also included in 1992 was a charge
of $13 million to record the cash settlement of class action claims resulting
from litigation relating to the use of airline fare data and gains of $32
million on the disposition of property, primarily one B747-SP aircraft,
seventeen B727 aircraft and four B737- 200 aircraft. In 1991, gains on the
disposition of property amounted to $49 million, which reflected sales of two
DC8-71s and four B727-100s.
 
OTHER INFORMATION
 
 Deferred Tax Asset
 
  United's consolidated balance sheet at December 31, 1993 includes a net
cumulative deferred tax asset of $697 million. The net deferred tax asset is
composed of approximately $1.9 billion of deferred tax assets and approximately
$1.2 billion of deferred tax liabilities. The deferred tax assets include,
among other things, $598 million related to obligations for postretirement and
other employee benefits, $480 million related to gains on sales and leasebacks
and $202 million related to alternative minimum tax ("AMT") credit
carryforwards which do not expire.
 
  The majority of the deferred tax assets will be realized through reversals of
existing deferred tax liabilities with similar reversal patterns. To realize
the benefits of the remaining deferred tax assets relating to temporary
differences, United needs to generate approximately $1.2 billion in future
taxable income. Based on the expectations for future taxable income, the
extended period over which postretirement benefits will be recognized, and the
indefinite carryforward period for AMT credits, management believes it is more
likely than not that the deferred tax assets will be realized.
 
  Although United has experienced both book and tax losses in the past three
years, in the ten years prior to these losses, United reported cumulative
taxable income of $2.8 billion (including $400 million of gains on dispositions
of businesses). Following is a summary of United's pretax book income and

   Taxable income (loss)......................... $(156) $(502) $(784) $274 $638
</TABLE>
 
  The losses in the past three years were largely attributable to certain
events beyond management control, including the Gulf war, the unanticipated
duration of the recession in both the U. S. and other areas of the world and
the proliferation of numerous low-cost air carriers resulting in severe
competition in the airline industry. While the economic outlook in Japan and
Europe could continue to negatively affect United's operating results,
management believes that these economies will begin to improve, and when
combined with certain cost containment strategies, United's financial results
should improve.
 
                                       21

  Management has already taken several steps to reduce costs and capital
expenditures. United's improved operating results in 1993 versus 1992 are
principally attributable to these actions, as highlighted below:
 
  . Implemented a program in January 1993 to reduce planned 1993 operating
    expenses by $400 million, including the furlough of 2,800 employees in
    February 1993.
 
  . Reached agreement with Boeing, its principal supplier, to convert 49
    aircraft orders into options and defer their scheduled delivery dates.
 
  . Reduced 1993 to 1996 capital spending by $6 billion.
 
  . Agreed to sell flight kitchens which will result in the avoidance of an
    estimated $70 million of capital expenditures and estimated cost savings
    of more than $320 million over the seven year catering contract with the
    purchaser, before taking into account the severance payments resulting
    from the employee investment transaction.
 
  . Accelerated the retirement of 25 older aircraft to reduce costs and
    improve operating efficiencies.
 
  . Negotiated over $100 million in annual savings from suppliers.
 
  . Reduced domestic capacity by eliminating certain unprofitable routes and
    reducing capacity in certain markets to better match demand.
 
  . Increased the use of cooperative arrangements with domestic and
    international carriers resulting in increased revenue opportunities
    through code-sharing.
 
  The long-term financial stability and profitability of the company is
expected to be further enhanced through the proposed employee investment
transaction. However, in the event the proposed employee investment transaction
does not occur, United is prepared to make additional structural changes to
return to profitablilty.
 
  United's ability to generate sufficient amounts of taxable income from future
operations is dependent upon numerous factors, including general economic
conditions, inflation, oil prices, the state of the industry and other factors
beyond management's control. In the event that future taxable income is
inadequate to realize the benefits of the remaining deferred tax assets, United
has identified certain tax planning strategies that would significantly
contribute to the utilization of these assets. These strategies include, among
other things, eliminating the prefunding of certain employee benefits and the
sale of unused route authorities.
 
  There can be no assurances that United will meet its expectation of future
taxable income. However, based on the above factors, management believes it is
more likely than not that future taxable income will be sufficient to utilize
the cumulative deferred tax assets at December 31, 1993.
 
CONTINGENCIES
 
  During 1992, United recorded a $13 million charge representing its share of
the cash component of a settlement of certain class action claims. Under the
settlement, which has been approved by the U.S. District Court, six airlines
paid approximately $45 million in cash and will issue $397 million in face
amount of certificates affording discounts of up to approximately 10% on future
air travel on any of the six carriers.
 
  No liability was established for the certificate portion of the settlement
since United expects that in the aggregate, future revenues associated with
certificate redemption will exceed the cost of providing the related air
service. United anticipates that the portion of the total issued certificates
that may be redeemed on United will approximate United's 22% market share among
the six carriers, but actual redemption may be greater or lesser.
 
  The ultimate impact of the settlement on United's future revenues, operating
margins and earnings is not reasonably estimable since neither the portion of
the certificates to be redeemed on United nor the generative or dilutive
revenue effect of certificate redemption is known.
 
 
                                       22
<PAGE>
 
  United has been named as a Potentially Responsible Party at certain
Environmental Protection Agency ("EPA") cleanup sites which have been
designated as Superfund Sites. At sites where the EPA has commenced remedial
litigation, potential liability is joint and several. United's alleged
proportionate contributions at the sites are minimal. Additionally, United has
participated and is participating in remediation actions at certain other
sites, primarily airports. The estimated cost of these actions is accrued when
it is determined that it is probable that United is liable. Such accruals have
not been material.
 
  United has certain other contingencies resulting from litigation and claims
incident to the ordinary course of business. Although the ultimate outcome of
these matters could have a material effect on United's financial condition,
operating results or liquidity, management believes, after considering a number
of factors, including (but not limited to) the views of legal counsel, the
nature of such contingencies and prior experience, that the ultimate
disposition of these contingencies is not likely to materially affect United's
financial condition, operating results or liquidity.
 
NEW ACCOUNTING STANDARDS
 
  In November 1992, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 112, "Employers' Accounting for Postemployment Benefits," which
requires recognition of the liability for postemployment benefits during the
period of employment. Such benefits include company paid continuation of group
life insurance and medical and dental coverage for certain employees after
employment but before retirement. United will adopt the new standard in the
first quarter of 1994. Based on preliminary estimates, United currently expects
to record a transition obligation, which will result in a cumulative charge of
$26 million, net of tax. Prior years' financial statements will not be
restated. Ongoing expenses will vary based on actual claims experience.
 
  In May 1993, the FASB issued SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," which requires fair value
accounting for certain investments. United is required to adopt the new
standard in 1994 and the standard is not to be applied retroactively. Upon
adoption, United will record a periodic charge or credit to adjust the carrying
value of certain investments to fair value. The adjustment will be recorded in
earnings or as a separate component of equity, depending on the type of
investment. United does not expect a material impact on either earnings or
equity as a result of adopting SFAS No. 115.
 
ENERGY TAX
 
  The Omnibus Budget Reconciliation Act of 1993 signed into law on August 10,
1993, imposes a 4.3 cent per gallon tax on commercial aviation jet fuel
purchased for use in domestic operations. This new fuel tax will become
effective October 1, 1995, and is scheduled to continue until October 1, 1998.
Based on United's 1993 domestic fuel consumption of 1.7 billion gallons, the
new fuel tax, when effective, is expected to increase United's operating
expenses by approximately $75 million annually.
 
FOREIGN CURRENCY TRANSACTIONS
 
  United generates revenues and incurs expenses in numerous foreign currencies;
however, United has limited exposure to foreign exchange rate fluctuations due
to its ability to convert excess local currencies generated to U.S. dollars. In
addition, United has exposure to transaction gains and losses resulting from
rate fluctuation. The foreign exchange gains and losses recorded in recent
years, including losses recorded in early 1993, were primarily the result of
the impact of exchange rate changes on unhedged Japanese yen- denominated long-
term debt, lease obligations and current liabilities, since the aggregate
balance of such liabilities exceeded United's yen-denominated assets. During
1993, United increased the amount of its yen-denominated assets to minimize the
impact of foreign exchange rate changes on reported financial results.
 
SALE OF FLIGHT KITCHENS
 
  In the third quarter of 1993, United reached agreements to sell assets
related to the operation of 16 of its flight kitchens to Dobbs International
Services, Inc. and Caterair International Corp. for $119 million. Under
 
                                       23
<PAGE>
 
the agreements, the purchasers will provide catering services for United at the
airports served by the flight kitchens for seven years. United expects the
catering agreement to result in savings of approximately $320 million over its
term, before taking into account the severance payments resulting from the
employee investment transaction. The asset sales for most, if not all, of the
flight kitchens are expected to be completed in the second quarter of 1994. The
asset sales result in an insignificant gain.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors,  
  United Air Lines, Inc.:
 
  We have audited the accompanying statement of consolidated financial position
of United Air Lines, Inc. (a Delaware corporation) and subsidiary companies as
of December 31, 1993 and 1992, and the related statements of consolidated
operations, consolidated cash flows and consolidated shareholder's equity for
each of the three years in the period ended December 31, 1993. These financial
statements and the schedules referred to below are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of United Air Lines, Inc. and
subsidiary companies as of December 31, 1993 and 1992, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1993, in conformity with generally accepted accounting principles.
 
  As discussed in notes 5 and 11 to the consolidated financial statements,
effective January 1, 1992, the Company changed its methods of accounting for
income taxes and postretirement benefits other than pensions.
 
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedules referenced in Item
14(a)(2) herein are presented for purposes of complying with the Securities and
Exchange Commission's rules and are not part of the basic financial statements.
These schedules have been subjected to the auditing procedures applied in the
audit of the basic financial statements and, in our opinion, fairly state in
all material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                    UAL CORPORATION AND SUBSIDIARY COMPANIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 (a) Consolidation--
 
  United Air Lines, Inc. ("United") is a wholly-owned subsidiary of UAL
Corporation ("UAL"). The consolidated financial statements include the accounts
of United and all of its subsidiaries. All significant intercompany
transactions are eliminated. Investments in affiliates are carried on the
equity basis.
 
 (b) Accounting Changes--
 
  Effective January 1, 1992, United adopted Statement of Financial Accounting
Standards ("SFAS") No. 106, "Employers' Accounting for Postretirement Benefits
Other Than Pensions" (see Note 11) and SFAS No. 109, "Accounting for Income
Taxes" (see Note 5).
 
 (c) Airline Revenues--
 
  Passenger fares and cargo revenues are recorded as operating revenues when
the transportation is furnished. The value of unused passenger tickets is
included in current liabilities.
 
 (d) Foreign Currency Transactions--
 
  Monetary assets and liabilities denominated in foreign currencies are
converted at exchange rates in effect at the balance sheet date. The resulting
foreign exchange gains and losses, and gains and losses on foreign currency
call options used to hedge foreign currency obligations, are charged or
credited directly to income.
 
 (e) Cash and Cash Equivalents and Short-term Investments--
 
  Cash in excess of operating requirements is pooled with funds from UAL and
its subsidiary companies and invested in short-term, highly liquid, income-
producing investments. Investments with an original maturity of three months or
less on their acquisition date are classified as cash and cash equivalents.
Cash and cash equivalents and short-term investments are stated at cost, which
approximates market value. Due to the short maturity of these instruments,
their carrying amount is a reasonable estimate of fair value.
 
 (f) Aircraft Fuel, Spare Parts and Supplies--
 
  Aircraft fuel and maintenance and operating supplies are stated at average
cost. Flight equipment spare parts are stated at average cost less an
obsolescence allowance.
 
 (g) Operating Property and Equipment--
 
  Owned operating property and equipment is stated at cost. Property under
capital leases, and the related obligation for future minimum lease payments,
are initially recorded at an amount equal to the then present value of those
lease payments.
 
  Depreciation and amortization of owned depreciable assets is based on the
straight-line method over their estimated service lives. Leasehold improvements
are amortized over the remaining period of the lease or the estimated service
life of the related asset, whichever is less. Aircraft are depreciated to
estimated salvage values, generally over lives of 10 to 25 years; buildings are
depreciated over lives of 25 to 45 years; and other property and equipment are
depreciated over lives of three to 15 years.
 
  Properties under capital leases are amortized on the straight-line method
over the life of the lease, or in the case of certain aircraft, over their
estimated service lives. Lease terms are 10 to 19 years for aircraft and

flight simulators and 25 years to 40 years for buildings. Amortization of
capital leases is included in depreciation and amortization expense.
 
  Gains or losses on dispositions of individual units of owned property and
equipment are reflected in earnings. Maintenance and repairs, including the
cost of minor replacements, are charged to maintenance expense accounts. Costs
of additions to and renewals of units of property are charged to property and
equipment accounts.
 
 (h) Intangibles--
 
  Intangibles consist primarily of route acquisition costs, slots and
intangible pension assets (see Note 10). Route acquisition costs and slots are
amortized over 40 years and 5 years, respectively.
 
 (i) Mileage Plus Awards--
 
  United accrues the estimated incremental cost of providing free travel awards
earned under its Mileage Plus frequent flyer program when such award levels are
reached.
 
 (j) Deferred Gains--
 
  Gains on aircraft sale and leaseback transactions are deferred and amortized
over the lives of the leases as a reduction of rental expense.
 
 (k) Interest Rate Swap Agreements--
 
  United enters into interest rate swap agreements to hedge certain interest
rate exposure. The differential to be paid or received under the swap
agreements is accrued and included in interest expense or rental expense.
 
(2) PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On December 22, 1993, the Board of Directors of UAL approved a non-binding
agreement in principle that would provide a majority equity interest in UAL to
the employees of United in exchange for wage concessions and work-rule changes.
In January 1994, the agreement was ratified by the Air Line Pilots Association
("ALPA") and the International Association of Machinists ("IAM"). The
transaction is subject to, among other things, approval by UAL stockholders.
 
  In the transaction, an Employee Stock Ownership Plan will be created to
provide United employees with a minimum of a 53% equity interest in UAL in
exchange for wage concessions and work-rule changes. The employee interest may
increase to up to 63%, depending on the average market value of UAL common
stock in the year after the transaction closes. The transaction is not
dependent on external financing.
 
  Pursuant to the terms of the agreement in principle, current UAL stockholders
would receive the remaining 37 to 47% of the common stock and $88 per share in
cash and face amount of debt and preferred stock. The non-common stock
consideration is expected to aggregate approximately $743 million of cash, $900
million face amount of senior unsecured debentures and $900 million face amount
of preferred stock depending on the number of common shares on which the
distribution is made. While the agreement in principle contemplates that the
debentures would be issued by UAL, such debentures could be issued by United.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  UAL agreed that if the transaction closes prior to August 31, 1994, severance
payments and employee benefits coverage approximating $50 million would be
provided by United to IAM employees being terminated from United as a result of
the recent sale of flight kitchens (see Note 16), in addition to payments
required under United's labor contracts. Certain of the severance payments,
which are to be made on a monthly basis, became payable in January 1994 after
the unions ratified the agreement; however, these monthly payments terminate
but are not refunded if the transaction does not close before August 31, 1994
or certain other conditions are not met. Other lump-sum severance amounts are
payable only if the transaction closes prior to the required date. UAL has also
agreed to pay up to $45 million of transaction fees and expenses incurred by
ALPA and the IAM if the transaction is closed by August 31, 1994. If the
transaction does not close by the required date but certain conditions are met,
UAL will pay up to $12.5 million of ALPA and IAM transaction expenses.
 
(3) MERGER OF AFFILIATES
 
  In September 1993, the Covia Partnership ("Covia"), a 50% owned affiliate of
United, and The Galileo Company Limited, a 25.9% owned affiliate of United,
merged. The merger resulted in the formation of the Apollo Travel Services
Partnership ("ATS") and the Galileo International Partnership ("Galileo"), two
general partnerships that are owned 77% and 38%, respectively, by United
through a wholly-owned subsidiary. Galileo owns the Apollo and Galileo computer
reservations systems. ATS is responsible for marketing, sales and support of
Apollo in the United States, Mexico and the Caribbean.
 
  Prior to the merger, United's investments in these companies were carried on
the equity basis. As a result of the merger and United's majority ownership of
ATS, the accounts of ATS are consolidated, resulting in non-cash increases of
$78 million in assets, $46 million in liabilities and $34 million in minority
interests as of the date of the merger. United's investment in Galileo is
carried on the equity basis. The accounting for the merger resulted in no
change in the book value of the assets and liabilities of the companies
combined. During the fourth quarter, Galileo recorded a charge for the cost of
eliminating duplicate facilities and operations. United's share of this charge
was recorded in "Equity in earnings (loss) of affiliates." The merger is
expected to create operating efficiencies by eliminating duplication.
 
  Under operating agreements with Covia prior to the merger, United provided
certain computer support services for, and purchased computer reservation
services, communications and other information from Covia. Revenues derived
from the sale of services to Covia amounted to approximately $21 million, $22
million and $31 million in 1993, 1992 and 1991, respectively. The cost to
United of services purchased from the Covia Partnership amounted to
approximately $168 million, $219 million, and $191 million in 1993, 1992 and
1991, respectively. Under operating agreements with Galileo subsequent to the
merger, United purchases computer reservation services from Galileo and ATS
provides marketing, sales and communication services for Galileo. Revenues
derived from the sale of services to Galileo amounted to approximately $58
million and the cost of services purchased from Galileo amounted to
approximately $47 million in 1993.

(5) INCOME TAXES
 
  United, its subsidiaries and other affiliated companies file a consolidated
federal income tax return with UAL. Under an intercompany tax allocation
policy, United and its subsidiaries compute, record, and pay UAL for their own
tax liability as if they were separate companies filing separate tax returns.
In determining their own tax liabilities, United and each of its subsidiaries
take into account all tax credits or benefits generated and utilized as
separate companies, and they are compensated for the aforementioned tax
benefits only if they would be able to use those benefits on separate company
bases.
 
  In 1993, United incurred a regular tax loss but had an alternative minimum
tax ("AMT") liability. The regular tax loss will be carried back to reduce
taxable income generated in previous years resulting in federal and state
refunds and additional AMT credits. Certain preferences, mainly depreciation
adjustments, have caused alternative minimum taxable income to exceed regular
taxable income, resulting in the AMT liability.
 
  The provision (credit) for income taxes is summarized as follows:

  United adopted SFAS No. 109 "Accounting for Income Taxes," effective January
1, 1992. This statement provides for an asset and liability approach to
accounting for income taxes. United recognized a tax benefit of $33 million for
the cumulative effect of adopting SFAS No. 109. Deferred income taxes (credit)
for 1993 and 1992 reflect the impact of "temporary differences" between amounts
of assets and liabilities for financial reporting purposes and such amounts as
measured by tax laws. These temporary differences are determined in accordance
with SFAS No. 109 and are more inclusive in nature than "timing differences" as
determined under previously applicable accounting principles.
 
  During 1991, deferred income taxes were provided for significant timing
differences in the recognition of revenue and expenses for tax and financial
statement purposes. Principally, these items consisted of the following: $81
million for depreciation and capitalized interest, $(62) million for gains on
sale and leaseback transactions, $32 million for gains on asset dispositions,
$(24) million for rent expense, $(31) for pension expense, $16 million for
other employee benefits and $12 million for prepaid commissions.
 
  Temporary differences and carryforwards which give rise to a significant
portion of deferred tax assets and liabilities for 1993 and 1992 are as
follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  United has determined, based on its history of operating earnings, available
carrybacks, expectations for the future and potential tax planning strategies,
that it is more likely than not that the deferred tax assets at December 31,
1993 will be realized before expiration.
 
  The significant differences between pretax book losses and taxable losses for
the last three years were as follows (in millions):

  At December 31, 1993, United and its subsidiaries had $202 million of federal
AMT credit carryforwards available for an indefinite period and $27 million of
state tax benefit from net operating loss carryforwards expiring between 1997
and 2009.
 
(6) SHORT-TERM BORROWINGS
 
  At December 31, 1993, United had outstanding $315 million in short-term
borrowings, bearing an average interest rate of 3.34%. Receivables amounting to
$367 million were pledged by United to secure repayment of such outstanding
borrowings. Due to the short maturity of these borrowings, their carrying
amount is a reasonable estimate of fair value. In February 1993, United entered
agreements to increase the maximum available amount of borrowings under this
arrangement from $450 million to $500 million. Pursuant to the terms of this
agreement, in the event of a change in control of United or UAL, such as the
proposed employee investment transaction, the lenders under this agreement may
decline to make new loans to United.
 
(7) LONG-TERM DEBT
 
  A summary of long-term debt, excluding current maturities, as of December 31
is as follows (interest rates are as of December 31, 1993):

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The fair value of long-term debt, including current maturities, at December
31, 1993 and 1992 were estimated to be $2.928 billion and $2.893 billion,
respectively, based on the quoted market prices for the same or similar issues
or on the then current rates offered for debt of the same remaining maturities.
 
  In the second quarter of 1993, United retired $500 million of senior
subordinated notes. The notes, bearing interest at 12.5% and 13%, were
scheduled to mature in 1995 and 1998 for $150 and $350 million, respectively.
An extraordinary loss of $19 million, net of tax benefits of $8 million, was
recorded in the first quarter of 1993, based on United's stated intention to
retire the notes.
 
  In May 1993, United issued $176 million of pass through certificates under a
1992 shelf registration to refinance aircraft under operating leases. In June
1993, a new shelf registration filed by UAL and United for up to $1.5 billion
of securities, including secured and unsecured debt, equipment trust and pass
through certificates, equity or a combination thereof, was declared effective.
Under the terms of the 1993 shelf registration statement, the 1992 shelf and a
1991 shelf, under which $394 million and $100 million, respectively, of
securities remained, were combined with the 1993 shelf. In November 1993,
United issued $118 million of pass through certificates under the shelf
registration to refinance aircraft under operating leases. In December 1993,
United issued $100 million of 6.75% debentures due 1997 under the shelf. On a
combined basis, up to $1.776 billion of additional securities may be offered at
December 31, 1993.
 
  In connection with 1993 aircraft financings, United issued $470 million of
secured notes due through 2013. Interest rates were fixed between 7.53% and
8.99% on $270 million of principal amount. Initial interest rates on the
remaining notes were 166 and 176 basis points over the London interbank offered
rate ("LIBOR") and will be 650 basis points over LIBOR after nine months. In
addition, during 1993, United retired $74 million of principal amount of
secured notes in connection with sale and leaseback transactions.
 
  At December 31, 1993, United had outstanding a total of $544 million of long-
term debt bearing interest at rates 85 to 176 basis points over LIBOR. In
connection with certain of these debt financings, United has entered interest
rate swap agreements to effectively fix interest rates at December 31, 1993
between 8.554% and 8.6% on $73 million of notional amount. The swap agreements
have terms of 18.5 years, corresponding to the terms of the related debt
obligations. Under the agreements, United makes payments to counterparties at
fixed rates and in return receives payments based on LIBOR. In the event of
default by the counterparties, United is exposed to credit risk for periodic
settlements due under the swap agreements; however, United does not anticipate
such default. The fair values of these swap agreements at December 31, 1993 and
1992 were $8 million and $3 million, respectively, representing the estimated
amount that United would pay to terminate the swap agreements, based on
interest rates in effect at the time.
 
  Maturities of long-term debt for each of the four years after 1994 are:
1995--$107 million; 1996--$112 million; 1997--$114 million; and 1998--$175
million.
 
  Various assets, principally aircraft, having an aggregate book value of
$1.634 billion at December 31, 1993, were pledged under various loan
agreements.
 
(8) LEASE OBLIGATIONS
 
  United leases aircraft, airport passenger terminal space, aircraft hangars
and related maintenance facilities, cargo terminals, flight kitchens, real
estate, office and computer equipment and vehicles.

</TABLE>
 
  As of December 31, 1993, United leased 298 aircraft, 45 of which were under
capital leases. These leases have terms of four to 26 years, and expiration
dates range from 1994 through 2017. Under the terms of leases for 287 of the
aircraft, United has the right of first refusal to purchase, at the end of the
lease term, certain aircraft at fair market value and others at either fair
market value or a percentage of cost. United has five Airbus A320-200 aircraft
under 24-year operating leases which are cancelable upon eleven months notice
during the initial 10 years of the leases.
 
  Amounts charged to rent expense, net of minor amounts of sublease rentals,
were $1.176 billion in 1993, $1.021 billion in 1992, and $854 million in 1991.
Included in rent expense for 1993 and 1992 were insignificant amounts of
contingent rentals, resulting from changes in interest rates for operating
leases under which the rent payments are based on variable interest rates. In
connection with certain of these leases, United has entered interest rate swap
agreements, with terms similar to those discussed in Note 7--Long-Term Debt. At
December 31, 1993, a notional amount of $415 million of interest rate swap
agreements effectively fixed interest rates between 8.02% and 8.65% on such
leases. The fair values of these swap agreements at December 31, 1993 and 1992
were $34 million and $8 million, respectively.
 
(9) FOREIGN OPERATIONS
 
  United conducts operations in various foreign countries, principally in the
Pacific, Europe and Latin America. Operating revenues from foreign operations
were approximately $5.560 billion in 1993, $4.863 billion in 1992 and $3.870
billion in 1991.
 
(10) RETIREMENT PLANS
 
  United has various retirement plans which cover substantially all employees.
Defined benefit plans covering certain employees (primarily union ground
employees) provide a stated benefit for specified periods of service, while
defined benefit plans for other employees provide benefits based on employees'
years of service and average compensation for a specified period of time before
retirement. Pension costs are funded to at least the minimum level required by
the Employee Retirement Income Security Act of 1974. The

company also provides several defined contribution plans which cover
substantially all U. S. employees who have completed one year of service. For
certain groups of employees (primarily pilots), the company contributes an
annual amount on behalf of each participant, calculated as a percentage of the
participants' earnings or a percentage of the participants' contributions.

  For the valuation of pension obligations as of December 31, 1993 and 1992,
the weighted average discount rates used were 7.5% and 8.75%, respectively, and
the rates of increase in compensation were 4.0% and 4.3%, respectively.
Substantially all of the accumulated benefit obligation is vested.
 
  Total pension expense for all retirement plans (including defined
contribution plans) was $346 million in 1993, $324 million in 1992, and $252
million in 1991.
 
  Plan assets are invested primarily in governmental and corporate debt
instruments and corporate equity securities. The expected average long-term
rate of return on plan assets at December 31 was 9.75% for 1993, 10.25% for
1992 and 11.25% for 1991.
 
  The net periodic pension cost of defined benefit plans included the following

(11) POSTRETIREMENT BENEFITS
 
  United provides certain life insurance and health care benefits for
substantially all retired employees. The estimated cost of life insurance
benefits is accrued and funded over the years of service of those employees
expected to qualify for such benefits. United provides various defined benefit
postretirement health care plans which pay stated percentages of most necessary
medical expenses incurred by retirees, after subtracting payments by Medicare
or other providers and after a stated deductible has been met. United funds
this plan as medical claims are paid. Effective January 1, 1992, United adopted
SFAS No. 106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions". This standard requires that the expected cost of postretirement
benefits be charged to expense during the years in which employees render
service. Upon adoption, United elected to record the transition obligation of
$925 million as a one-time charge against earnings. Prior to 1992, the cost of
health care benefits was recognized as expense as claims were paid. The total
cost of these postretirement benefits was $33 million in 1991.
 
  Information on the plans' funded status, on an aggregate basis at December
31, follows (in millions):

  For the valuation of the accumulated postretirement benefit obligation as of
December 31, 1993 and 1992, the discount rate was 7.5% and 8.75%, respectively.
An 11% and 12% annual rate of increase in the per capita cost of covered health
care was assumed for 1993 and 1992, respectively; the rate is assumed to
decrease annually to a rate of 4% by the year 2001, remaining level thereafter.
The effect of a 1% increase in the assumed health care cost trend rate would
increase the accumulated postretirement benefit obligation at December 31,
1993, by $175 million and the aggregate of the service and interest cost
components of net postretirement benefit cost for 1993 by $21 million.
 
(12) RELATED PARTY TRANSACTIONS
 
  In 1992 and 1991, UAL made capital contributions of $60 million and $192
million, respectively, to United. In 1991, UAL also made a capital contribution
to United of its investment in United Vacations, Inc., a wholly-owned
subsidiary. At December 31, 1993 and 1992, United had accounts receivable from
UAL of $361 million and $288 million, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Certain officers and key employees of United participate in UAL stock award
plans. Under UAL's incentive stock option program, stock appreciation rights
("SARs") were granted in tandem with certain stock options prior to 1992. On
exercise of these SARs, holders would receive in cash 100% of the appreciation
in fair market value of the UAL shares subject to the SAR. The estimated
payment value of SARs, net of market value adjustments, was charged to United's
earnings over the vesting period. In 1992, all active officers relinquished
their SARs but retained the tandem stock options. The expense (credit) recorded
for SARs was $1 million in 1993, $(1) million in 1992 and $18 million in 1991.
In February 1994, UAL reinstated the use of SARs and 818,370 SARs were
authorized in tandem with existing options with an outstanding average option
price of $128.50. The SARs are not exercisable until September 1, 1994, and
will expire if the employee investment transaction is consummated.
 
  Under UAL's restricted stock plan, 138,500 and 101,750 shares of UAL common
stock were awarded to officers and key employees of United in 1993 and 1991,
respectively. No shares were issued under this plan in 1992. In 1993, 1992 and
1991, 9,000, 6,500 and 4,200 shares, respectively, were forfeited under this
plan. Unearned compensation, representing the fair market value of the stock on
the date of award, is being amortized to salaries and related costs over the
vesting period.
 
  Air Wis Services, Inc. ("Air Wis") became a wholly-owned subsidiary of UAL in
January 1992. Air Wis owns Air Wisconsin, Inc. In April 1993, UAL transferred
the Air Wisconsin, Inc. operations at Dulles to Atlantic Coast Airlines. In
September 1993, UAL transferred certain Air Wisconsin, Inc. operations at
O'Hare to United Feeder Services. In December 1993, UAL transferred the jet
operations of Air Wisconsin, Inc. to CJT Holdings. These operations are being
conducted by the counterparties in these agreements under the United Express
trade name. These actions are not expected to have a material effect on
United's results of operations or financial position. At December 31, 1993 and
1992, United had outstanding loans to Air Wisconsin, Inc. in the amount of $80
million and $58 million, respectively, bearing interest at market rates.
 
(13) COMMITMENTS AND CONTINGENCIES
 
  United 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
United is subject and its prior experience, that the ultimate disposition of
these contingencies is not expected to materially affect United's consolidated
financial position or results of operations.
 
  At December 31, 1993, commitments for the purchase of property and equipment,
principally aircraft, approximated $4.3 billion after deducting advance
payments. An estimated $0.6 billion is expected to be expended during 1994,
$1.1 billion in 1995, $0.8 billion in 1996, $1.2 billion in 1997, $0.4 billion
in 1998, and $0.2 billion after 1998. The major commitments are for the
purchase of thirty-four B777 aircraft, which are expected to be delivered
between 1995 and 1999. These amounts reflect United's revised capital spending
plan and agreements with The Boeing Company, to convert certain aircraft orders
into options. Under the terms of the agreements, if United does not elect to
confirm the delivery of these option aircraft before 1998, it will forfeit
significant deposits.
 
  In addition to the B777 order, United has arrangements with Airbus and
International Aero Engines to lease an additional 45 A320 aircraft, which are
scheduled for delivery through 1998. Under the agreement, United is making
advance payments through 1996 which are refundable upon delivery of each
aircraft.
 
  At December 31, 1993, United also had purchase options for 186 B737 aircraft,
54 B757 aircraft, 34 B777 aircraft, 52 B747 aircraft, eight B767 aircraft and
50 A320 aircraft. Consistent with its revised capital

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

spending plan, United has recently cancelled options on certain aircraft. In
January 1994, United entered an agreement with Boeing to acquire two B747-400
aircraft in 1994 and cancelled options for two B747 aircraft. These aircraft
are not included in the commitment amounts above.
 
  As of December 31, 1993, United had guaranteed $97 million of indebtedness of
affiliates. Special facility revenue bonds have been issued by certain
municipalities to build or improve airport facilities leased by United. Under
the lease agreements, United is required to make rental payments in amounts
sufficient to pay the maturing principal and interest payments on the bonds. At
December 31, 1993, $907 million principal amount of such bonds was outstanding.
Payment of United's obligations with respect to $40 million of this amount is
secured through standby letters of credit. As of December 31, 1993, UAL and
United had jointly guaranteed $35 million of such bonds and United had
guaranteed $841 million of such bonds, including accrued interest. Included in
this amount are bonds issued by the City of Denver in connection with the
construction of certain United facilities at Denver International Airport,
which will replace Stapleton International Airport ("Stapleton"). Denver has
agreed to retire the outstanding special facility revenue bonds related to
United's Stapleton facilities. The new airport is expected to open in 1994.
 
  Transfers of the tax benefits of accelerated depreciation and investment tax
credits associated with the acquisition of certain equipment have been made
previously by United to various tax lessors through tax lease transactions.
Proceeds from tax benefit transfers were recognized as income in the year the
lease transactions were consummated. The subject equipment is being depreciated
for book purposes. United has agreed to indemnify (guaranteed in some cases by
UAL) the tax lessors against loss of such benefits in certain circumstances and
has agreed to indemnify others for loss of tax benefits in limited
circumstances for certain used aircraft purchased by United subject to previous
tax lease transactions. Certain tax lessors have required that letters of
credit be issued in their favor by financial institutions as security for
United's indemnity obligations under the leases. The outstanding balance of
such letters of credit totaled $68 million at December 31, 1993. At that date,
United had granted mortgages on aircraft and engines having a total book value
of $252 million as security for indemnity obligations under tax leases and
letters of credit.
 
  United is in the process of constructing a maintenance facility in
Indianapolis, which begins operation in 1994. The facility is being financed
primarily with tax-exempt bonds and other capital sources. In connection with
incentives received, United has agreed to reach an $800 million capital
spending target and employ at least 6,300 individuals.
 
  United does not believe it is subject to any significant concentration of
credit risk. Most of United's receivables result from sales of tickets to
individuals through travel agents, company outlets or other airlines, often
through the use of major credit cards. These receivables are short term,
generally being settled shortly after the sale.
 
(14) NEW ACCOUNTING STANDARDS
 
  In November 1992, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 112, "Employers' Accounting for Postemployment Benefits," which
requires recognition of the liability for postemployment benefits during the
period of employment. Such benefits include company paid continuation of group
life insurance and medical and dental coverage for certain employees after
employment but before retirement. United will adopt the new standard in the
first quarter of 1994. Based on preliminary estimates, United currently expects
to record a transition obligation which will result in a cumulative charge of
$26 million, net of tax. Prior years' financial statements will not be
restated. Ongoing expenses will vary based on actual claims experience.

                    UAL CORPORATION AND SUBSIDIARY COMPANIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  In May 1993, the FASB issued SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," which requires fair value
accounting for certain investments. United is required to adopt the new
standard in 1994 and the standard is not to be applied retroactively. Upon
adoption, United will record a periodic charge or credit to adjust the carrying
value of certain investments to fair value. The adjustment will be recorded in
earnings or as a separate component of equity, depending on the type of
investment. United does not expect a material impact on either earnings or
equity as a result of adopting SFAS No. 115.

  In the third quarter of 1993, United reached agreements to sell assets
related to the operation of 16 of its flight kitchens to Dobbs International
Services, Inc. and Caterair International Corp. for $119 million. Under the
agreements, the purchasers will provide catering services for United at the
airports served by the flight kitchens for seven years. The asset sales for
most, if not all, of the flight kitchens are expected to be finalized in the
second quarter of 1994. The asset sales result in an insignificant gain.

  In the second quarter of 1993, United retired $500 million of senior
subordinated notes. An extraordinary loss of $19 million, net of tax benefits
of $8 million, was recorded in the first quarter of 1993, based on United's
stated intention to retire the notes.
 
  In the third quarter of 1993, United recorded a charge of $59 million to
reduce the net book value of 15 DC-10 aircraft to estimated net realizable
value. In addition, third quarter earnings included a $17 million gain and
interest income of $27 million resulting from the final settlement for
overpayment of annuities purchased in 1985 to cover certain vested pension
benefits. The 1993 fourth quarter included $53 million of equity in the loss of
Galileo, which primarily reflects United's share of a charge recorded by
Galileo for the cost of eliminating duplicate facilities and operations.
 
  Effective January 1, 1992, United adopted SFAS No. 106, "Employers'
Accounting for Postretirement Benefits Other than Pensions" and SFAS No. 109,
"Accounting for Income Taxes." The effect of adopting SFAS No. 106 was a
cumulative charge of $580 million, net of tax benefits of $345 million. The
effect of adopting SFAS No. 109 was a cumulative benefit of $33 million.
 
  In the 1992 fourth quarter, operating expenses included charges of $18
million for certain foreign employee benefits and certain taxes. In addition,
operating expenses included charges of $25 million related to the announced
cost reduction program. The 1992 second quarter included a $13 million non-
operating charge to record the cash settlement of class action claims resulting
from litigation relating to the use of airline fare data.

                    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 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 1993.
 
PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On March 24, 1994, the Board of Directors of UAL approved a plan of
recapitalization, dated March 25, 1994, that would provide a majority equity
interest in UAL to the employees of United in exchange for wage concessions and
work-rule changes. The transaction is subject to approval by UAL shareholders
and certain closing conditions.
 
RECLASSIFICATION
 
  In the first quarter of 1994, United began recording certain air
transportation price adjustments, which were previously recorded as
commissions, as adjustments to revenue. Certain amounts in the Statement of
Consolidated Operations for the first quarter of 1993 have been reclassified to
conform with the current presentation.
 
OTHER INCOME (EXPENSE)--MISCELLANEOUS
 
  Included in "Miscellaneous, net" in the first quarter of 1994 was a charge of
$19 million for costs incurred in connection with the proposed employee
investment transaction. In addition, the 1994 and 1993 periods included foreign
exchange losses of $1 million and $22 million, respectively.
 
INCOME TAXES
 
  The provisions (credits) for income taxes are based on estimated annual
effective tax rates which differ from the federal statutory rate of 35%
principally due to state income taxes and certain nondeductible expenses. The
estimated annual effective tax rate for the first quarter of 1994 is based on
the actual effective tax rate for the quarter. Deferred tax assets are
recognized based upon UAL's history of operating earnings, available
carrybacks, expectations for the future and potential tax planning strategies.
 
ACCOUNTING CHANGES
 
  UAL adopted Statement of Financial Accounting Standards ("SFAS") No. 112,
"Employers' Accounting for Postemployment Benefits," effective January 1, 1994.
SFAS No. 112 requires recognition of the liability for postemployment benefits
during the period of employment. Such benefits include company paid
continuation of group life insurance and medical and dental coverage for
certain employees after

employment but before retirement. The effect of adopting SFAS No. 112 was a
cumulative charge for recognition of the transition liability of $42 million,
before tax benefits of $16 million. The ongoing expenses related to
postemployment benefits will vary based on actual claims experience.
 
  UAL also adopted SFAS No. 115, "Accounting for Certain Investments in Debt
and Equity Securities," effective January 1, 1994. UAL's investments in such
securities are included in "Cash and cash equivalents" and "Short-term
investments." The following information pertains to UAL's investments in such
securities at March 31, 1994 (in millions):

  The net unrealized holding loss on available-for-sale securities of $3
million has been recorded as a component of shareholders' equity, net of
related tax benefits. The proceeds from sales of available-for-sale securities
for the three months ended March 31, 1994 were $175 million, which, based on
the cost of securities sold, resulted in insignificant gross realized gains and
losses. These gains and losses were included in interest income for the period.
 
PER SHARE AMOUNTS
 
  Per share amounts were calculated after providing for preferred stock
dividends of $9 million in the first quarter of 1994 and $5 million in the
first quarter of 1993.
 
AFFILIATES
 
  United owns 38% of the Galileo International Partnership ("Galileo") through
a wholly-owned subsidiary. United's investment in Galileo, which owns the
Apollo and Galileo computer reservations systems, is carried on the equity
basis. United also owns 77% of the Apollo Travel Services Partnership ("ATS")
and, accordingly, its accounts are consolidated for the first quarter of 1994.
Prior to a September 1993 merger, United owned 50% of the Covia Partnership
("Covia"), one of Galileo's and ATS's predecessor companies, which was
accounted for on the equity basis.
 
  Under operating agreements with Covia prior to the merger, United provided
certain computer support services for, and purchased computer reservation
services, communications and other information from, Covia. Revenues derived
from the sale of services to Covia amounted to approximately $12 million and
the cost of services purchased from Covia amounted to approximately $58 million
in the first quarter of 1993. Under operating agreements with Galileo
subsequent to the merger, United purchases computer reservation services from
Galileo and provides marketing, sales and communication services for Galileo.
Revenues derived from the sale of services to Galileo amounted to approximately
$59 million and the cost of services purchased from Galileo amounted to
approximately $21 million in the first quarter of 1994.

LONG-TERM DEBT
 
  In the second quarter of 1993, United retired $500 million of senior
subordinated notes. The notes were scheduled to mature in 1995 and 1998 for
$150 million and $350 million, respectively. An extraordinary loss of $19
million, net of tax benefits of $9 million, was recorded in the first quarter
of 1993, based on United's stated intention to retire the notes.
 
PREFERRED STOCK
 
  Effective March 31, 1994, UAL changed the stated capital of its cumulative
6.25% convertible preferred stock from $30 million ($5.00 per preferred share)
to $60,000 ($0.01 per preferred share), with the difference being attributed to
additional capital invested, which is included in other shareholders' equity.
 
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 March 31, 1994, commitments for the purchase of property and equipment,
principally aircraft, approximated $4.4 billion, after deducting advance
payments. An estimated $0.7 billion will be spent during the remainder of 1994,
$1.1 billion in 1995, $0.8 billion in 1996, $1.2 billion in 1997, $0.4 billion
in 1998, and $0.2 billion after 1998. The major commitments are for the
purchase of two B747 aircraft to be delivered this year and thirty-four B777
aircraft which are expected to be delivered between 1995 and 1999. These
amounts reflect United's revised capital spending plan and an agreement with
The Boeing Company, announced in April 1993, to convert certain aircraft orders
into options. Under the terms of the agreement, if United does not elect to
confirm the delivery of these option aircraft before 1998, it would forfeit
significant deposits.
 
  In addition to the B747 and B777 orders, United has arrangements with Airbus
Industrie and International Aero Engines to lease 41 A320 aircraft, which are
scheduled for delivery through 1998. At

      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)--(CONCLUDED)

March 31, 1994, United also had options for an additional 180 B737 aircraft, 49
B757 aircraft, 34 B777 aircraft, 49 B747 aircraft, 8 B767 aircraft and 50 A320
aircraft.
 
FOREIGN CURRENCY TRANSACTIONS
 
  In the first quarter of 1994, United entered into a foreign currency swap
contract to replace existing short-term foreign currency call options and
forward contracts in order to reduce exposure to currency fluctuations in
connection with certain Japanese yen-denominated obligations. The currency swap
contract, which was designated as a hedge, had a notional amount of $499
million at March 31, 1994. The notional amount will reduce periodically as
payments are made. Foreign currency gains and losses on the portion of the
contract hedging recorded obligations are included in income currently, exactly
offsetting the foreign currency losses and gains on the obligations. Currency
gains and losses on the difference between the gross future cash flows and the
recorded obligations are deferred and included in interest as it accrues.
United's theoretical risk in the swap is the cost of replacing the contract at
current market rates in the event of default by the counterparty; however,
United does not anticipate such default.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On March 24, 1994, the Board of Directors of UAL approved a plan of
recapitalization, dated March 25, 1994, that would provide a minimum 53% equity
interest in UAL to the employees of United in exchange for wage concessions and
work-rule changes. The transaction would be implemented through the creation of
Employee Stock Ownership Plans ("ESOPs") for United employees. The employee
interest may increase to up to 63%, depending on the average market value of
UAL common stock in the year after the transaction closes. Pursuant to the
terms of the plan of recapitalization, current UAL shareholders would receive
the remaining 37% to 47% of the common stock and $88 per share in cash and face
amount of debt and preferred stock. The transaction is subject to approval by
UAL shareholders and certain closing conditions.
 
  If approved, the employee investment transaction would put in place a lower
cost structure and allow for the creation of a low-cost short-haul operation.
The purpose of these changes is to create a cost structure which would allow
United to compete effectively against the low-cost carriers currently
influencing the domestic marketplace and improve UAL's long-term financial
viability.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  UAL's total of cash, cash equivalents and short-term investments increased
$238 million in the first quarter of 1994 to a balance of $2.066 billion at
March 31, 1994. Cash flows from operating activities amounted to $317 million.
Partially offsetting this was cash used in financing activities of $122
million, which included principal payments under capital lease and debt
obligations of $55 million and $13 million, respectively, and a $46 million
reduction of short-term borrowings.
 
  In the first quarter of 1994, United took delivery of four A320 aircraft,
which were acquired under operating leases. Other 1994 first quarter property
additions, primarily spare parts, amounted to $75 million, while property
dispositions resulted in proceeds of $96 million.
 
  At March 31, 1994, commitments for the purchase of property and equipment,
principally aircraft, approximated $4.4 billion, after deducting advance
payments. An estimated $0.7 billion will be spent during the remainder of 1994,
$1.1 billion in 1995, $0.8 billion in 1996, $1.2 billion in 1997, $0.4 billion
in 1998, and $0.2 billion after 1998. The major commitments are for the
purchase of two B747 aircraft to be delivered this year and thirty-four B777
aircraft which are expected to be delivered between 1995 and 1999. These
amounts reflect United's revised capital spending plan and an agreement with
The Boeing Company, announced in April 1993, to convert certain aircraft orders
into options. Under the terms of the agreement, if United does not elect to
confirm the delivery of these option aircraft before 1998, it would forfeit
significant deposits.
 
  In addition to the B747 and B777 orders, United has arrangements with Airbus
Industrie and International Aero Engines to lease 41 A320 aircraft, which are
scheduled for delivery through 1998. At March 31, 1994, United also had options
for an additional 180 B737 aircraft, 49 B757 aircraft, 34 B777 aircraft, 49
B747 aircraft, 8 B767 aircraft and 50 A320 aircraft. United continually reviews
its fleet to determine whether aircraft acquisitions will be used to expand the
fleet or to replace older aircraft, depending on market and regulatory
conditions at the time of delivery. Funds necessary to finance aircraft
acquisitions are expected to be obtained from internally generated funds,
irrevocable external financing arrangements or other external sources.
 
  UAL and United have a shelf registration statement on file with the
Securities and Exchange Commission under which up to $1.776 billion of
securities may be offered, including secured and unsecured debt, equipment
trust and pass through certificates, equity or a combination thereof. The shelf
registration statement is being utilized for purposes of registering $900
million principal amount of debentures to be issued upon consummation of the
employee investment transaction or thereafter upon conversion of outstanding
securities currently convertible into, or exercise of outstanding options
currently exercisable for, UAL common stock.

  The employee investment transaction, if approved, would have an initial
adverse effect on UAL's cash flow as a result of the cash consideration paid to
existing UAL shareholders and certain other recapitalization costs. However,
the transaction is expected to result in an improvement to cash flow through
the term of the employee investment. This improvement is expected to result
from the employee concessions which reduce cash expenses, partially offset by
the additional interest expense on the debentures, dividends on the preferred
stock and foregone interest on the cash consideration distributed to existing
shareholders.
 
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, 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.
 
  The employee investment transaction would impact UAL's results as operating
expenses would be reduced due to wage and benefit reductions, work-rule changes
and the startup of a new short-haul, low-cost operation. These expense
reductions would be offset by non-cash compensation charges for stock
periodically released to employees from the ESOPs and additional interest
expense on the debentures. The amount of the non-cash compensation expense
cannot be predicted, since it is based on the future fair value of UAL's stock.
 
  Due to the delay in the opening of the new Denver International Airport,
United's 1994 operating expenses are not expected to increase as First Quarter
1994 Compared with First Quarter 1993.
 
  UAL's results of operations in the first quarter of 1994 improved as compared
to 1993. In the first quarter of 1994, UAL recorded a net loss of $97 million,
$4.37 per share, compared to a 1993 first quarter net loss of $157 million,
$6.69 per share. The 1994 first quarter results include a $26 million
cumulative effect charge for the adoption of Statement of Financial Accounting
Standards No. 112, "Employers' Accounting for Postemployment Benefits," which
UAL adopted effective January 1, 1994. The first quarter 1993 results include
an extraordinary loss of $19 million on the early extinguishment of debt.
 
  UAL's financial statements have been affected by recent structural changes.
The September 1993 merger of the Covia Partnership and The Galileo Company
Limited resulted in the formation of Apollo Travel Services ("ATS"), which is
77% owned by United, and the consolidation of ATS's accounts with those of UAL.
In 1993, UAL also transferred the operations of Air Wisconsin, Inc. to other
parties, the effect of which was to reduce UAL's gross operating revenues and
expenses. In addition, the sales of flight kitchen assets in late 1993 and
early 1994 had the effect of reducing United's salaries and related costs and
increasing, to a lesser degree, catering costs.
 
  In the first quarter of 1994, United also began recording certain air
transportation price adjustments, which were previously recorded as
commissions, as adjustments to revenue. Operating revenue and expense amounts
and related operating statistics for the first quarter of 1993 have been
adjusted to conform with the current presentation.
 
  The significant factors affecting UAL's consolidated operations for the first
quarter of 1994 are described below.
 
  Operating revenues increased $142 million (5%). Passenger revenues increased
$21 million (1%) due to a 4% increase in United's revenue passenger miles,
offset by a 1% decrease in yield to 11.85 cents. The
 
                                       11
<PAGE>
 
increase in United's revenue passenger miles occurred systemwide, with the
Atlantic increase the largest at 7%. Available seat miles generally increased,
except in Latin America, where available seat miles decreased 10%, resulting in
an increase of 7.8 points in the Latin American load factor to 64.9%. Domestic
passenger load factor increased 1.7 points to 62.4%. On a system basis,
United's available seat miles increased 1% and passenger load factor increased
1.7 points to 65.4%. In addition, Air Wisconsin, Inc. accounted for $60 million
of passenger revenues in the first quarter of 1993.
 
  Cargo revenues increased $21 million (15%), due primarily to increased
freight revenues, as mail revenues were relatively unchanged. Freight and mail
revenue ton miles increased 5% and 6%,respectively; however, freight yield
increased 15% while mail yield decreased 5%. Other operating revenues increased
$100 million (63%) primarily as a result of the consolidation of ATS, revenues
resulting from the lease of Air Wisconsin, Inc. assets to other parties and an
increase in fuel sales.
 
  Operating expenses increased $57 million (2%). United's cost per available
seat mile increased 2% as well to 9.04 cents. Salaries and related costs
increased $38 million (3%) primarily due to higher average wage rates and
higher costs associated with pensions and medical benefits, partially offset by
a lower number of employees as a result of the flight kitchen sales.
Commissions increased $31 million (10%) due principally to increased travel
agency sales and higher freight volumes. Food and beverages increased $16
million (21%) due to the new catering arrangements resulting from the flight
kitchen sales. An increase of $14 million (4%) in rentals and landing fees
reflects rent associated with new aircraft acquired on operating leases,
primarily B767, B747 and A320 aircraft. Aircraft maintenance increased $9
million (9%) as a result of higher vendor-provided maintenance. Other operating
expenses increased $56 million (27%) due to higher fuel sales, the
consolidation of ATS and depreciation in the 1994 period on Air Wisconsin, Inc.
assets leased to others.
 
  Aircraft fuel expense decreased $55 million (13%), due to an 11% decrease in
United's average price per gallon of fuel to 58.6 cents and a 1% decrease in
United's consumption. Purchased services decreased $22 million (9%), as certain
services, principally computer reservations and communications, are now
provided by ATS. Depreciation and amortization decreased $15 million (8%) due
principally to the transfer of Air Wisconsin, Inc. assets to other parties and
the subsequent classification of depreciation on those assets in other
expenses.
 
  Other expense amounted to $72 million in the first quarter of 1994 compared
to $83 million in the first quarter of 1993. Interest expense decreased $12
million (13%) due primarily to the extinguishment of $500 million of
subordinated debt in 1993. Interest capitalized decreased $10 million (50%) as
a result of lower advance payments on new aircraft. Included in "Miscellaneous,
net" in the first quarter of 1994 was a charge of $19 million for fees and
costs incurred in connection with the proposed employee investment transaction.
In addition, the 1994 and 1993 periods included foreign exchange losses of $1
million and $22 million, respectively.
 
  The reduction in the foreign currency loss from 1993 was due to increased
hedging activity which minimized the impact of foreign exchange rate changes on
reported financial results. In the first quarter of 1994, United also entered
into a foreign currency swap contract to replace short-term foreign currency
call options and forward contracts previously used to hedge certain yen-
denominated obligations. Foreign currency gains and losses on the portion of
the swap contract hedging recorded obligations are included in income
currently, exactly offsetting the foreign currency losses and gains on the
obligations. Currency gains and losses on the difference between the gross
future cash flows and the recorded obligations are deferred and included in
interest as it accrues.

ITEM 2.LEGAL PROCEEDINGS
 
  In Re UAL Shareholder Litigation (Krasner v. UAL Corp. et al, Stepak v. UAL
Corp., Berger v. UAL Corp., Berger and Lewis v. UAL Corporation, et al.).--In
August and September 1989, four purported class action complaints by
Registrant's shareholders against Registrant and its Board of Directors in the
Circuit Court of Cook County were consolidated. The complaints alleged that (1)
Registrant's directors breached their fiduciary duties to the shareholders in
connection with the Board's dealings with Marvin Davis, an investor allegedly
interested in acquiring Registrant, as part of a larger scheme of entrenchment
by the Board of Directors; (2) fees paid by Registrant in connection with a
1989 attempt by Airline Acquisition Corp. to acquire Registrant should be
reimbursed to UAL; and (3) the Board's acceptance of a 1990 offer by United
Employee Acquisition Corp. to acquire Registrant was improper because the offer
was unfairly low. On March 17, 1994, the Court approved the settlement
previously agreed to by the parties, and awarded plaintiffs attorney's fees and
costs and expenses.

                UNITED AIR LINES, INC. AND SUBSIDIARY COMPANIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(UNAUDITED)

THE COMPANY
 
  United Air Lines, Inc. ("United") is a wholly-owned subsidiary of UAL
Corporation ("UAL").
 
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 United 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
month periods have been made. These financial statements should be read in
conjunction with the consolidated financial statements and footnotes thereto
included in United's Annual Report on Form 10-K for the year 1993.
 
PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On March 24, 1994, the Board of Directors of UAL approved a plan of
recapitalization, dated March 25, 1994, that would provide a majority equity
interest in UAL to the employees of United in exchange for wage concessions and
work-rule changes. The transaction is subject to approval by UAL shareholders
and certain closing conditions.
 
RECLASSIFICATION
 
  In the first quarter of 1994, United began recording certain air
transportation price adjustments, which were previously recorded as
commissions, as adjustments to revenue. Certain amounts in the Statement of
Consolidated Operations for the first quarter of 1993 have been reclassified to
conform with the current presentation.
 
OTHER INCOME (EXPENSE)--MISCELLANEOUS
 
  Included in "Miscellaneous, net" in the first quarter of 1994 was a charge of
$19 million for costs incurred in connection with the proposed employee
investment transaction. In addition, the 1994 and 1993 periods included foreign
exchange losses of $1 million and $22 million, respectively.
 
INCOME TAXES
 
  The provisions (credits) for income taxes are based on estimated annual
effective tax rates which differ from the federal statutory rate of 35%
principally due to state income taxes and certain nondeductible expenses. The
estimated annual effective tax rate for the first quarter of 1994 is based on
the actual effective tax rate for the quarter. Deferred tax assets are
recognized based upon United's history of operating earnings, available
carrybacks, expectations for the future and potential tax planning strategies.
 
ACCOUNTING CHANGES
 
  United adopted Statement of Financial Accounting Standards ("SFAS") No. 112,
"Employers' Accounting for Postemployment Benefits," effective January 1, 1994.
SFAS No. 112 requires recognition of the liability for postemployment benefits
during the period of employment. Such benefits include company paid
continuation of group life insurance and medical and dental coverage for
certain employees after employment but before retirement. The effect of
adopting SFAS No. 112 was a cumulative charge for recognition of the transition
liability of $42 million, before tax benefits of $16 million. The ongoing
expenses related to postemployment benefits will vary based on actual claims
experience.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  United also adopted SFAS No. 115, "Accounting for Certain Investments in Debt
and Equity Securities," effective January 1, 1994. United's investments in such
securities are included in "Cash and cash equivalents" and "Short-term
investments." The following information pertains to United's investments in
such securities at March 31, 1994 (in millions):

</TABLE>
 
  The net unrealized holding loss on available-for-sale securities of $3
million has been recorded as a component of shareholder's equity, net of
related tax benefits. The proceeds from sales of available-for-sale securities
for the three months ended March 31, 1994 were $94 million, which, based on the
cost of securities sold, resulted in insignificant gross realized gains and
losses. These gains and losses were included in interest income for the period.
 
AFFILIATES
 
  United owns 38% of the Galileo International Partnership ("Galileo") through
a wholly-owned subsidiary. United's investment in Galileo, which owns the
Apollo and Galileo computer reservations systems, is carried on the equity
basis. United also owns 77% of the Apollo Travel Services Partnership ("ATS")
and, accordingly, its accounts are consolidated for the first quarter of 1994.
Prior to a September 1993 merger, United owned 50% of the Covia Partnership
("Covia"), one of Galileo's and ATS's predecessor companies, which was
accounted for on the equity basis.
 
  Under operating agreements with Covia prior to the merger, United provided
certain computer support services for, and purchased computer reservation
services, communications and other information from, Covia. Revenues derived
from the sale of services to Covia amounted to approximately $12 million and
the cost of services purchased from Covia amounted to approximately $58 million
in the first quarter of 1993. Under operating agreements with Galileo
subsequent to the merger, United purchases computer reservation services from
Galileo and provides marketing, sales and communication services for Galileo.
Revenues derived from the sale of services to Galileo amounted to approximately
$59 million and the cost of services purchased from Galileo amounted to
approximately $21 million in the first quarter of 1994.
 
  Summarized financial information of Galileo follows (in millions):

LONG-TERM DEBT
 
  In the second quarter of 1993, United retired $500 million of senior
subordinated notes. The notes were scheduled to mature in 1995 and 1998 for
$150 million and $350 million, respectively. An extraordinary loss of $19
million, net of tax benefits of $9 million, was recorded in the first quarter
of 1993, based on United's stated intention to retire the notes.
 
CONTINGENCIES AND COMMITMENTS
 
  United 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
United is subject and its prior experience, that the ultimate disposition of
these contingencies is not expected to materially affect United's consolidated
financial position or results of operations.
 
  At March 31, 1994, commitments for the purchase of property and equipment,
principally aircraft, approximated $4.4 billion, after deducting advance
payments. An estimated $0.7 billion will be spent during the remainder of 1994,
$1.1 billion in 1995, $0.8 billion in 1996, $1.2 billion in 1997, $0.4 billion
in 1998, and $0.2 billion after 1998. The major commitments are for the
purchase of two B747 aircraft to be delivered this year and thirty-four B777
aircraft which are expected to be delivered between 1995 and 1999. These
amounts reflect United's revised capital spending plan and an agreement with
The Boeing Company, announced in April 1993, to convert certain aircraft orders
into options. Under the terms of the agreement, if United does not elect to
confirm the delivery of these option aircraft before 1998, it would forfeit
significant deposits.
 
  In addition to the B747 and B777 orders, United has arrangements with Airbus
Industrie and International Aero Engines to lease 41 A320 aircraft, which are
scheduled for delivery through 1998. At March 31, 1994, United also had options
for an additional 180 B737 aircraft, 49 B757 aircraft, 34 B777 aircraft, 49
B747 aircraft, 8 B767 aircraft and 50 A320 aircraft.
 
FOREIGN CURRENCY TRANSACTIONS
 
  In the first quarter of 1994, United entered into a foreign currency swap
contract to replace existing short-term foreign currency call options and
forward contracts in order to reduce exposure to currency fluctuations in
connection with certain Japanese yen-denominated obligations. The currency swap
contract, which was designated as a hedge, had a notional amount of $499
million at March 31, 1994. The notional amount will reduce periodically as
payments are made. Foreign currency gains and losses on the portion of the
contract hedging recorded obligations are included in income currently, exactly
offsetting the foreign currency losses and gains on the obligations. Currency
gains and losses on the difference between the gross future cash flows and the
recorded obligations are deferred and included in interest as it accrues.
United's theoretical risk in the swap is the cost of replacing the contract at
current market rates in the event of default by the counterparty; however,
United does not anticipate such default.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
PROPOSED EMPLOYEE INVESTMENT TRANSACTION
 
  On March 24, 1994, the Board of Directors of UAL approved a plan of
recapitalization, dated March 25, 1994, that would provide a minimum 53% equity
interest in UAL to the employees of United in exchange for wage concessions and
work-rule changes. The transaction would be implemented through the creation of
Employee Stock Ownership Plans ("ESOPs") for United employees. The employee
interest may increase to up to 63%, depending on the average market value of
UAL common stock in the year after the transaction closes. Pursuant to the
terms of the plan of recapitalization, current UAL shareholders would receive
the remaining 37% to 47% of the common stock and $88 per share in cash and face
amount of debt and preferred stock. The transaction is subject to approval by
UAL shareholders and certain closing conditions.
 
  If approved, the employee investment transaction would put in place a lower
cost structure and allow for the creation of a low-cost short-haul operation.
The purpose of these changes is to create a cost structure which would allow
United to compete effectively against the low-cost carriers currently
influencing the domestic marketplace and improve United's long-term financial
viability.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  United's total of cash, cash equivalents and short-term investments increased
$242 million in the first quarter of 1994 to a balance of $1.208 billion at
March 31, 1994. Cash flows from operating activities amounted to $287 million.
Partially offsetting this was cash used in financing activities of $110
million, which included principal payments under capital lease and debt
obligations of $55 million and $9 million, respectively, and a $46 million
reduction of short-term borrowings.
 
  In the first quarter of 1994, United took delivery of four A320 aircraft,
which were acquired under operating leases. Other 1994 first quarter property
additions, primarily spare parts, amounted to $66 million, while property
dispositions resulted in proceeds of $93 million.
 
  At March 31, 1994, commitments for the purchase of property and equipment,
principally aircraft, approximated $4.4 billion, after deducting advance
payments. An estimated $0.7 billion will be spent during the remainder of 1994,
$1.1 billion in 1995, $0.8 billion in 1996, $1.2 billion in 1997, $0.4 billion
in 1998, and $0.2 billion after 1998. The major commitments are for the
purchase of two B747 aircraft to be delivered this year and thirty-four B777
aircraft which are expected to be delivered between 1995 and 1999. These
amounts reflect United's revised capital spending plan and an agreement with
The Boeing Company, announced in April 1993, to convert certain aircraft orders
into options. Under the terms of the agreement, if United does not elect to
confirm the delivery of these option aircraft before 1998, it would forfeit
significant deposits.
 
  In addition to the B747 and B777 orders, United has arrangements with Airbus
Industrie and International Aero Engines to lease 41 A320 aircraft, which are
scheduled for delivery through 1998. At March 31, 1994, United also had options
for an additional 180 B737 aircraft, 49 B757 aircraft, 34 B777 aircraft, 49
B747 aircraft, 8 B767 aircraft and 50 A320 aircraft. United continually reviews
its fleet to determine whether aircraft acquisitions will be used to expand the
fleet or to replace older aircraft, depending on market and regulatory
conditions at the time of delivery. Funds necessary to finance aircraft
acquisitions are expected to be obtained from internally generated funds,
irrevocable external financing arrangements or other external sources.
 
  UAL and United have a shelf registration statement on file with the
Securities and Exchange Commission under which up to $1.776 billion of
securities may be offered, including secured and unsecured debt, equipment
trust and pass through certificates, equity or a combination thereof. The shelf
registration statement is being utilized for purposes of registering $900
million principal amount of debentures to be issued upon consummation of the
employee investment transaction or thereafter upon conversion of outstanding
 
                                       9
<PAGE>
 
securities currently convertible into, or exercise of outstanding options
currently exercisable for, UAL common stock.
 
  The employee investment transaction, if approved, would have an initial
adverse effect on United's cash flow as a result of the payment of certain fees
and transaction expenses. However, the transaction is expected to result in an
improvement to cash flow through the term of the employee investment. This
improvement is expected to result from the employee concessions which reduce
cash expenses, partially offset by the additional interest expense on the
debentures.
 
RESULTS OF OPERATIONS
 
  United'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, 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.
United 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.
 
  The employee investment transaction would impact United's results as
operating expenses would be reduced due to wage and benefit reductions, work-
rule changes and the startup of a new short-haul, low-cost operation. These
expense reductions would be offset by non-cash compensation charges for stock
periodically released to employees from the ESOPs and additional interest
expense on the debentures. The amount of the non-cash compensation expense
cannot be predicted, since it is based on the future fair value of UAL's stock.
 
  Due to the delay in the opening of the new Denver International Airport,
United's 1994 operating expenses are not expected to increase as much as
originally anticipated.
 
FIRST QUARTER 1994 COMPARED WITH FIRST QUARTER 1993.
 
  United's results of operations in the first quarter of 1994 improved as
compared to 1993. In the first quarter of 1994, United recorded a net loss of
$105 million, compared to a 1993 first quarter net loss of $148 million. The
1994 first quarter results include a $26 million cumulative effect charge for
the adoption of Statement of Financial Accounting Standards No. 112,
"Employers' Accounting for Postemployment Benefits," which UAL adopted
effective January 1, 1994. The first quarter 1993 results include an
extraordinary loss of $19 million on the early extinguishment of debt.
 
  United's financial statements have been affected by recent structural
changes. The September 1993 merger of the Covia Partnership and The Galileo
Company Limited resulted in the formation of Apollo Travel Services ("ATS"),
which is 77% owned by United, and the consolidation of ATS's accounts with
those of United. In addition, the sales of flight kitchen assets in late 1993
and early 1994 had the effect of reducing United's salaries and related costs
and increasing, to a lesser degree, catering costs.
 
  In the first quarter of 1994, United also began recording certain air
transportation price adjustments, which were previously recorded as
commissions, as adjustments to revenue. Operating revenue and expense amounts
and related operating statistics for the first quarter of 1993 have been
adjusted to conform with the current presentation.
 
  The significant factors affecting United's consolidated operations for the
first quarter of 1994 are described below.
 
 
                                       10
<PAGE>
 
  Operating revenues increased $172 million (6%). Passenger revenues increased
$81 million (3%) due to a 4% increase in United's revenue passenger miles,
offset by a 1% decrease in yield to 11.85 cents. The increase in United's
revenue passenger miles occurred systemwide, with the Atlantic increase the
largest at 7%. Available seat miles generally increased, except in Latin
America, where available seat miles decreased 10%, resulting in an increase of
7.8 points in the Latin American load factor to 64.9%. Domestic passenger load
factor increased 1.7 points to 62.4%. On a system basis, United's available
seat miles increased 1% and passenger load factor increased 1.7 points to
65.4%.
 
  Cargo revenues increased $21 million (15%), due primarily to increased
freight revenues, as mail revenues were relatively unchanged. Freight and mail
revenue ton miles increased 5% and 6%, respectively; however, freight yield
increased 15% while mail yield decreased 5%. Other operating revenues increased
$70 million (42%) primarily as a result of the consolidation of ATS and an
increase in fuel sales.
 
  Operating expenses increased $109 million (4%). United's cost per available
seat mile increased 2% to 9.04 cents. Salaries and related costs increased $60
million (5%) primarily due to higher average wage rates and higher costs
associated with pensions and medical benefits, partially offset by a lower
number of employees as a result of the flight kitchen sales. Commissions
increased $36 million (12%) due principally to increased travel agency sales
and higher freight volumes. Food and beverages increased $16 million (21%) due
to the new catering arrangements resulting from the flight kitchen sales. An
increase of $29 million (8%) in rentals and landing fees reflects rent
associated with new aircraft acquired on operating leases, primarily B767, B747
and A320 aircraft. Aircraft maintenance increased $16 million (17%) as a result
of higher vendor-provided maintenance. Other operating expenses increased $34
million (16%) due to higher fuel sales and the consolidation of ATS.
 
  Aircraft fuel expense decreased $50 million (12%), due to an 11% decrease in
United's average price per gallon of fuel to 58.6 cents and a 1% decrease in
United's consumption. Purchased services decreased $19 million (8%), as certain
services, principally computer reservations and communications, are now
provided by ATS.
 
  Other expense amounted to $76 million in the first quarter of 1994 compared
to $84 million in the first quarter of 1993. Interest expense decreased $11
million (12%) due primarily to the extinguishment of $500 million of
subordinated debt in 1993. Interest capitalized decreased $10 million (50%) as
a result of lower advance payments on new aircraft. Included in "Miscellaneous,
net" in the first quarter of 1994 was a charge of $19 million for fees and
costs incurred in connection with the proposed employee investment transaction.
In addition, the 1994 and 1993 periods included foreign exchange losses of $1
million and $22 million, respectively.
 
  The reduction in the foreign currency loss from 1993 was due to increased
hedging activity which minimized the impact of foreign exchange rate changes on
reported financial results. In the first quarter of 1994, United also entered
into a foreign currency swap contract to replace short-term foreign currency
call options and forward contracts previously used to hedge certain yen-
denominated obligations. Foreign currency gains and losses on the portion of
the swap contract hedging recorded obligations are included in income
currently, exactly offsetting the foreign currency losses and gains on the
obligations. Currency gains and losses on the difference between the gross
future cash flows and the recorded obligations are deferred and included in
interest as it accrues.

  otherwise included therein relating to (1) the UAL Corporation Employee

                          INCENTIVE COMPENSATION PLAN
 
                           (AS AMENDED JUNE 30, 1988)

                                UAL CORPORATION
 
                          INCENTIVE COMPENSATION PLAN
 
                                  (THE "PLAN")
 
I. PURPOSE
 
  In an effort to maintain a position of leadership in the fast-growing and
highly competitive business segments in which UAL Corporation (the "Company")
competes, it is necessary to promote financial interests of the corporation and
its corporate affiliates (the "subsidiaries"), including its growth, by (A)
attracting and retaining highly qualified executives possessing outstanding
ability, (B) motivating executives by means of performance related incentives,
and (C) providing incentive compensation opportunities which are competitive
with those of major corporations. The Incentive Compensation Plan hereinafter
described is designated to assist the Company in attaining these objectives.
 
II. ADMINISTRATION OF THE PLAN
 
  1. The Company is responsible for the general administration of the Plan,
except as to matters reserved in this Plan to the Compensation and Stock Option
Committee of the Board of Directors (the "Committee"). Determinations,
decisions and actions of the Company or the Committee in connection with the
construction, interpretation, administration, or application of the Plan will
be final, conclusive, and binding upon any grantee of awards under the Plan and
any person claiming under or through such grantee. Neither the Company nor any
member of the Committee will be liable for any determination, decision, or
action made with respect to the Plan or any Incentive Award granted under the
Plan.
 
  2. A Participant's rights and interests in any Incentive Award made under the
Plan may not be assigned or transferred and are not subject to attachment,
garnishment, execution, or other creditors' processes.
 
  3. This Plan may at any time be amended, modified, or terminated as the
Board, in its discretion, determines, and such amendment, modification, or
termination will not require the consent, ratification, or approval of any
party, including any Participant hereunder.
 
  4. This Plan and all determinations made and actions taken pursuant hereto
will be governed and construed by the law of the State of Illinois.
 
III. DEFINITIONS
 
  1. Award Year--The calendar year for which Incentive Awards, if any, are
calculated under the Plan.
 
  2. Financial Objectives--Financial performance goals established by the
Company and approved by the Committee at the beginning of an Award Year.
Financial Objectives may apply to overall Company and subsidiaries performance
in selected areas and/or to performance of major business segments of the
Company and subsidiaries.
   
  3. Financial Performance Factor--The numerical factor determined by the
Company shortly after the Award Year by comparing actual performance during
such Award Year to the applicable Financial Performance Objectives previously
established for such Award Year.     
   
  4. Individual Performance Objectives--Goals and objectives established by the
Company (or by the Committee in the case of the Company's Chairman and its
Chief Executive Officer) for each Participant under the Plan.     
 
  5. Individual Performance Factor--The numerical factor determined with
respect to the Plan by the Company (or by the Committee in the case of the
Chairman and the Chief Executive Officer and officers reporting to either of
them) shortly after the Award Year, based upon an evaluation as to the extent
to
<PAGE>
 
which a Participant in the Plan achieved the Individual Performance Objectives
established for him/her. Such evaluation will be wholly discretionary and
subjective on the part of the Company or the Committee.
 
  6. Incentive Awards--The dollar value of awards made to Participants under
the Plan. Notwithstanding any other provisions of the Plan, in no event may a
total Incentive Award for any Participant exceed 100% of his/her base salary
for an Award Year.
 
  7. Incentive Opportunity--The amount, determined by the Company and approved
by the Committee at the beginning of an Award Year, that a Participant may
receive as an Incentive Award under the Plan. The Incentive Opportunity will be
stated as a percentage of a Participant's annual base salary as of December 31,
of an Award Year. If a Participant held more than one position in an Award
Year, his/her Incentive Opportunity will be based on the position he/she
occupied at the end of the Award Year.
 
IV. PARTICIPATION IN THE PLAN
 
  1. Participants will be determined annual by the Company from among key
employees and senior management employees of the Company and its subsidiaries.
This determination will allow participation only for the Award Year concerned.
 
  2. The Plan does not constitute a contract of employment, and participation
in the Plan will not give any employee the right to be retained in the service
of the Company or its subsidiaries.
 
  3. If a Participant's employment with the Company or its subsidiaries is
terminated during an Award Year, the appropriate Incentive Award under the
Plan, if any, for such Participant will be subject to the sole discretion of
the Company's Chairman (or to the sole discretion of the committee in case of
the termination of employment of the Chairman). A transfer of employment
between the Company and any of its subsidiaries will not be considered a
termination of employment.
 
V. COMPUTATION OF INCENTIVE AWARDS
 
  The Incentive Award for an Award Year for a Participant will be the product
of a Participant's Incentive Opportunity times the sum of his company's
Financial Performance Factor plus his Individual Performance Factor. No
Incentive Award will be made to a Participant for an Award Year in which his
company's Financial Performance Factor is below threshold level. However, the
Chairman, with Committee approval, may waive the Company's Financial
Performance Factor threshold requirement.
 
  Total payments to all participants of the Incentive Compensation Plan will be
limited to 5% of Pre-Tax Income in any given year. Should total calculated
incentive awards exceed 5% of Pre-Tax Income, payments will be made on a
prorated basis.
 
VI. PAYMENT OF AWARDS--Payment of Incentive Awards will be made in cash on or
about April 1, of the year following the Award Year.

                              AMENDMENT TO THE UAL
                    CORPORATION INCENTIVE COMPENSATION PLAN
 
  UAL CORPORATION (the "Company"), having heretofore adopted the UAL
Corporation Incentive Compensation Plan, as amended June 30, 1988 (the "Plan"),
hereby amends the Plan, effective as of the date of consummation of the
Recapitalization to be effected pursuant to the Agreement and Plan of
Recapitalization proposed to be entered into among the Company, Air Line Pilots
Association, International and International Association of Machinists and
Aerospace Workers, as follows:
   
  1. The first sentence of Paragraph 1 of Section II of the plan is hereby
amended in its entirety to read as follows:     
       
    "The Company is responsible for the general administration of the Plan,
    except as to matters reserved in this Plan to the Compensation
    Administration Committee of the Board of Directors (the "Committee"),
    provided however, that the Plan shall be administered by the Committee
    to the extent necessary to cause the amounts payable hereunder to
    satisfy the requirements of Section 162(m)(4)(C) of the Internal
    Revenue Code of 1986, as amended the "Code").     
   
  2. Section VI of the Plan is hereby amended in its entirety to read as
follows:     
 
    "VI. PAYMENT OF AWARDS
 
  A) Standard Procedures--Payment of Incentive Awards will be made in cash on
     or about April 1, of the year following the Award Year; provided,
     however, that an Incentive Award may be deferred at the election of a
     Participant in the manner described below.
     
  B) Deferred Awards--Participants may elect, on or before December 31 of the
     year preceding an Award Year, to defer receipt of all or any portion of
     an Incentive Award to a subsequent calendar year. A Participant will
     receive payment of a deferred Incentive Award in a lump sum in January
     of the earliest of: (1) the deferral calendar year selected by the
     Participant; (2) the calendar year immediately after the Participant's
     retirement under the United Air Lines, Inc. Non-Union Ground Employees'
     Retirement Plan; (3) the calendar year after the Participant's
     termination of employment with the Company for other reasons, provided
     that a transfer of employment from the Company to any of the Company's
     affiliates will not be considered a termination of employment with the
     Company; (4) the occurrence of an "Unforeseeable Emergency", provided
     that a distribution pursuant to this clause (4) shall not exceed the
     amount reasonably needed to satisfy the emergency need, or (5) any other
     time elected by the Participant, provided that upon making such an
     election, the Participant shall be entitled to receive 90% of the
     amounts then credited to him or her under the Plan and shall forfeit the
     remaining 10% of such amount. The amounts deferred will be credited
     annually with compound interest at the prime rate in effect during the
     deferral period at the end of the calendar quarter, as reported by The
     Wall Street Journal. All deferred Incentive Awards will be reflected in
     the Company's books as general unsecured and unfunded obligations of the
     Company. No trust in favor of any Participant will be implied. Deferral
     elections will be irrevocable by a Participant or his or her
     beneficiary. For purposes of this Section, "Unforeseeable Emergency"
     shall mean a severe financial hardship to the Participant resulting from
     a sudden and unexpected illness or accident of the Participant or of a
     dependent (as defined in Section 152(a) of the Code) of the Participant,
     loss of the Participant's property due to casualty, or other similar
     extraordinary and unforeseeable circumstances arising as a result of
     events beyond the control of the Participant. The circumstances that
     will constitute an Unforeseeable Emergency will depend upon the facts of
     each case, but, in any case, payment under clause (4) above may not be
     made to the extent that such hardship is or may be relieved (i) through
     reimbursement or compensation by insurance or otherwise, (ii) by
     liquidation of the Participant's assets, to the extent the liquidation
     of     
<PAGE>
 
     such assets would not itself cause severe financial hardship, or (iii)
     by cessation of deferrals under the Plan."
   
  3. The Plan is hereby amended by adding a new Section VII at the end thereof
to read as follows:     
 
    "VII. SPECIAL RULES
 
    Notwithstanding any other provision of this Plan to the contrary,
    Incentive Awards with respect to an Award Year with respect to any
    Participant who is a "covered employee" (as defined in Section 162(m)(3)
    of the Code) with respect to such Award Year (i) may not exceed $900,000
    and (ii) shall be determined by reference to a formula which shall
    define the Incentive Award by reference to the attainment by the Company
    of one or more target levels of pre-tax income (as determined under
    generally accepted accounting principles but without regard to any items
    (whether gains or losses) otherwise included therein relating to (1) the
    UAL Corporation Employee Stock Ownership Plan, the UAL Corporation
    Supplemental ESOP, or the trusts relating thereto, (2) any event or
    occurrence that the Committee determines to be either not directly
    related to the operations of the Company or not within the reasonable
    control of the Company's management, (3) the Plan and (4) the Company's
    1988 Restricted Stock Plan) for such Award Year. Such target level(s)
    and the formula referred to above shall be determined by the Committee
    prior to the commencement of such Award Year (or at such later time as
    may be permissible under Section 162(m) of the Code). Notwithstanding
    the foregoing, the Committee may reduce the Incentive Award otherwise
    determined pursuant to such formula in its sole discretion."

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the General Corporation Law of Delaware empowers each of the
Registrants to indemnify, subject to the standards herein prescribed, any
person in connection with any action, suit or proceeding brought or threatened
by reason of the fact that such person is or was a director, officer, employee
or agent of a Registrant or was serving as such with respect to another
corporation or other entity at the request of a Registrant. Article Sixth (b)
of each of the Registrants' Restated Certificates of Incorporation provides
that each person who was or is made a party to (or is threatened to be made a
party to) or is otherwise involved in any action, suit or proceeding by reason
of the fact that such person is or was a director or officer of the applicable
Registrant shall be indemnified and held harmless by the applicable Registrant
to the fullest extent authorized by the General Corporation Law of Delaware
against all expense, liability and loss (including, without limitation,
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid or to be paid in settlement) reasonably incurred by such person in
connection therewith. The rights conferred by Article Sixth (b) are contractual
rights and include the right to be paid by the applicable Registrant the
expenses incurred in defending such action, suit or proceeding in advance of
the final disposition thereof.
 
  Article SIXTH (a) of each of the Registrants' Restated Certificate of
Incorporation and the proposed Restated Certificate of Incorporation of UAL
provides that the applicable Registrant's directors will not be personally
liable to the applicable Registrant or its stockholders for monetary damages
resulting from breaches of their fiduciary duty as directors except for
liability (a) for any breach of the duty of loyalty to the applicable
Registrant or its stockholders, (b) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (c) under
Section 174 of the General Corporation Law of Delaware, which makes directors
liable for unlawful dividends or unlawful stock repurchases or redemptions or
(d) for any transaction from which directors derive improper personal benefit.
 
  The Registrants maintain directors and officers liability insurance covering
all directors and officers of the Registrants against claims arising out of the
performance of their duties.

ITEM 22. UNDERTAKINGS
 
  (a) Each of the undersigned Registrants hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933, as amended (the "Securities Act");
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement;
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change of such information in the Registration Statement;
 
    (2) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new Registration Statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.
 
    (3) To remove from registration by means of post-effective amendment any
  of the securities being registered which remain unsold at the termination
  of the offering.
 
  (b) Each of the undersigned Registrants hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of a
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
  (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions, or otherwise, the Registrants
have been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by a
Registrant of expenses incurred or paid by a director, officer or controlling
person of such Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the applicable Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
  (d) Each of undersigned Registrants hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, 13, or 16 of this form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the Registration Statement
through the date of responding to the request.
 
  (e) Each of the undersigned Registrants hereby undertakes to supply by means
of a post-effective amendment all information concerning a transaction that was
not the subject of and included in the Registration Statement when it became
effective.

                      FORM OF RECEIPTS, DEPOSIT OF STOCK,
                       EXECUTION AND DELIVERY, TRANSFER,
                      SURRENDER AND REDEMPTION OF RECEIPTS

     SECTION 2.1  Form and Transfer of Receipts.  Definitive Receipts shall be
                  -----------------------------                               
engraved or printed or lithographed on steel-engraved borders, with appropriate

insertions, modifications and omissions as hereinafter provided, if required by
any securities exchange on which the Receipts are listed.  Pending the

the written order of the Company or any holder of Stock, as the case may be,
delivered in compliance with Section 2.2, shall execute and deliver temporary
Receipts that are printed, lithographed, typewritten, mimeographed or otherwise

benefits under this Agreement, and with respect to the Stock, as definitive
Receipts.

     Receipts shall be executed by the Depositary by the manual signature of a
duly authorized officer of the Depositary; provided that such signature may be a
                                           --------                             
facsimile if a Registrar for the Receipts (other than the Depositary) shall
have been appointed and such Receipts are countersigned by a manual signature of
a duly authorized officer of the Registrar.  No Receipt shall be entitled to
any benefits under this Deposit Agreement or be valid or obligatory for any
purpose unless it shall have been executed manually by a duly authorized officer
of the Depositary or, if a Registrar for the Receipts (other than the
Depositary) shall have been appointed, by manual or facsimile signature of a
duly authorized offi-

cer of the Depositary and countersigned manually by a duly authorized officer of
such Registrar.  The Depositary shall record on its books each Receipt so
signed and delivered as hereinafter provided.

     Receipts shall be in denominations of any number of whole Depositary
Shares.  The Company shall deliver to the Depositary from time to time such
quantities of Receipts as the Depositary may request to enable the Depositary
to perform its obligations under this Deposit Agreement.

     Receipts may be endorsed with or have incorporated in the text thereof
such legends or recitals or changes not inconsistent with the provisions of this
Deposit Agreement as may be required by the Depositary or required to comply
with any applicable law or any regulation thereunder or with the rules and
regulations of any securities exchange upon which the Stock, the Depositary
Shares or the Receipts may be listed or to conform with any usage with respect
thereto, or to indicate any special limitations or restrictions to which any
particular Receipts are subject.

     Title to Depositary Shares evidenced by a Receipt, which is properly
endorsed or accompanied by a properly executed instrument of transfer, shall be
transferable by delivery with the same effect as in the case of a negotiable
instrument; provided that until transfer of a Receipt shall be registered on the
            --------                                                            
books of the Depositary as provided in Section 2.3, the Depositary may,
notwithstanding any notice to the contrary, treat the record holder thereof at
such time as the absolute owner thereof for the purpose of determining the
person entitled to distributions of dividends or other distributions or to any
notice provided for in this Deposit Agreement and for all other purposes.

     SECTION 2.2  Deposit of Stock; Execution and Delivery of Receipts in
                  -------------------------------------------------------
Respect Thereof.  Subject to the terms and conditions of this Deposit Agreement,
- ---------------                                                                 
the Company or any holder of Stock may from time to time deposit shares of the
Stock under this Deposit Agreement by delivering to the Depositary a
certificate or certificates for the Stock to be deposited, properly endorsed or
accompanied, if required by the Depositary, by a duly executed instrument of
transfer or endorsement, in form

satisfactory to the Depositary, together with all such certifications as may be
required by the Depositary in accordance with the provisions of this Deposit
Agreement, and together with a written order of the Company or such holder, as
the case may be, directing the Depositary to execute and deliver to, or upon the
written order of, the person or persons stated in such order a Receipt or
Receipts for the number of Depositary Shares representing such deposited Stock.

     Deposited Stock shall be held by the Depositary at the Depositary's Office
or at such other place or places as the Depositary shall determine.

     Upon receipt by the Depositary of a certificate or certificates for Stock
deposited in accordance with the provisions of this Section, together with the
other documents required as above specified, and upon recordation of the Stock
on the books of the Company in the name of the Depositary or its nominee, the
Depositary, subject to the terms and conditions of this Deposit Agreement, shall
execute and deliver, to or upon the order of the person or persons named in the
written order delivered to the Depositary referred to in the first paragraph of
this Section, a Receipt or Receipts for the whole number of Depositary Shares
representing the Stock so deposited and registered in such name or names as may
be requested by such person or persons.  The Depositary shall execute and
deliver such Receipt or Receipts at the Depositary's Office or such other
offices, if any, as the Depositary may designate.  Delivery at other offices
shall be at the risk and expense of the person requesting such delivery.

     SECTION 2.3  Registration of Transfer of Receipts.  Subject to the terms
                  ------------------------------------                       
and conditions of this Deposit Agreement, the Depositary shall register on its
books from time to time transfers of Receipts upon any surrender thereof by the
holder in person or by duly authorized attorney, properly endorsed or
accompanied by a properly executed instrument of transfer.  Thereupon, the
Depositary shall execute a new Receipt or Receipts evidencing the same aggregate
number of Depositary Shares as those evidenced by the Receipt or Receipts
surrendered and deliver such new Receipt or Receipts to or upon the order of the
person entitled thereto.

                                       5
<PAGE>
 
     SECTION 2.4  Split-ups and Combinations of Receipts; Surrender of Receipts
                  -------------------------------------------------------------
and Withdrawal of Stock.  Upon surrender of a Receipt or Receipts at the
- -----------------------                                                 
Depositary's Office or at such other offices as it may designate for the purpose
of effecting a split-up or combination of such Receipt or Receipts, and subject
to the terms and conditions of this Deposit Agreement, the Depositary shall
execute and deliver a new Receipt or Receipts in the authorized denomination or
denominations requested, evidencing the aggregate number of Depositary Shares
evidenced by the Receipt or Receipts surrendered, provided that the Depositary
                                                  --------                    
shall not issue any Receipt evidencing a fractional Depositary Share.

     Any holder of a Receipt or Receipts representing any number of whole
shares of Stock may (unless the related Depositary Shares have previously been
called for redemption) withdraw the Stock and all money and other property, if
any, represented thereby by surrendering such Receipt or Receipts, at the
Depositary's Office or at such other offices as the Depositary may designate for
such withdrawals.  Thereafter, without unreasonable delay, the Depositary shall
deliver to such holder, or to the person or persons designated by such holder as
hereinafter provided, the number of whole shares of Stock and all money and
other property, if any, represented by the Receipt or Receipts so surrendered
for withdrawal, but holders of such whole shares of Stock shall not thereafter
be entitled to deposit such Stock hereunder or to receive Depositary Shares
therefor.  If a Receipt delivered by the holder to the Depositary in connection
with such withdrawal shall evidence a number of Depositary Shares in excess of
the number of Depositary Shares representing the number of whole shares of Stock
to be so withdrawn, the Depositary shall at the same time, in addition to such
number of whole shares of Stock and such money and other property, if any, to be
so withdrawn, deliver to such holder, or upon his order, a new Receipt
evidencing such excess number of Depositary Shares, provided that the Depositary
                                                    --------                    
shall not issue any Receipt evidencing a fractional Depositary Share.  Delivery
of the Stock and money and other property being withdrawn may be made by the
delivery of such certificates, documents of title and other instruments as the
Depositary may deem appropriate that, if required by the Depositary, shall be
properly endorsed or accompanied by proper instruments of transfer.

                                       6
<PAGE>
 
     If the Stock and the money and other property being withdrawn are to be
delivered to a person or persons other than the record holder of the Receipt or
Receipts being surrendered for withdrawal of Stock, such holders shall execute
and deliver to the Depositary a written order so directing the Depositary and
the Depositary may require that the Receipt or Receipts surrendered by such
holder for withdrawal of such shares of Stock be properly endorsed in blank or
accompanied by a properly executed instrument of transfer in blank.

     Delivery of the Stock and the money and other property, if any, represented
by Receipts surrendered for withdrawal shall be made by the Depositary at the
Depositary's Office, except that, at the request, risk and expense of the holder
surrendering such Receipt or Receipts and for the account of the holder thereof,
such delivery may be made at such other place as may be designated by such
holder.

     SECTION 2.5  Limitations on Execution and Delivery, Transfer, Surrender and
                  --------------------------------------------------------------
Exchange of Receipts.  As a condition precedent to the execution and delivery,
- --------------------                                                          
registration of transfer, split-up, combination, surrender or exchange of any
Receipt, the Depositary, any of the Depositary's Agents or the Company may
require payment to it of a sum sufficient for the payment (or, if the
Depositary or the Company shall have made such payment, the reimbursement to
it) of any charges or expenses payable by the holder of a Receipt pursuant to
Sections 3.2 and 5.7, may require the production of evidence satisfactory to it
as to the identity and genuineness of any signature and may also require
compliance with such regulations, if any, as the Depositary or the Company may
establish consistent with the provisions of this Deposit Agreement.

     The deposit of Stock may be refused, the delivery of Receipts against
Stock may be suspended, the registration of transfer of Receipts may be refused
and the registration of transfer, surrender or exchange of outstanding Receipts
may be suspended (i) during any period when the register of stockholders of the
Company is closed, (ii) if any such action is deemed necessary or advisable by
the Depositary, any of the Depositary's Agents or the Company at any time or
from time to time because of any requirement of law or of any government or

                                       7
<PAGE>
 
governmental body or commission or under any provision of this Deposit Agreement
or (iii) with the approval of the Company, for any other reason.

     SECTION 2.6  Lost Receipts, etc.  If any receipt shall be mutilated,
                  -------------------                                     
destroyed, lost or stolen, the Depositary in its discretion may execute and
deliver a Receipt of like form and tenor in exchange and substitution for such
mutilated Receipt, or in lieu of and in substitution for such destroyed, lost or
stolen Receipt, upon (i) the filing by the holder thereof with the Depositary
of evidence satisfactory to the Depositary of such destruction or loss or theft
of such Receipt, of the authenticity thereof and of his or her ownership
thereof, (ii) the furnishing of the Depositary with reasonable indemnification
satisfactory to it and (iii) the payment of any expense (including fees, charges
and expenses of the Depositary) in connection with such execution and delivery.

     SECTION 2.7  Cancellation and Destruction of Surrendered Receipts.  All
                  ----------------------------------------------------      
Receipts surrendered to the Depositary or any Depositary's Agent shall be
cancelled by the Depositary.  Except as prohibited by applicable law or
regulation, the Company is authorized to destroy all Receipts so cancelled.

     SECTION 2.8  Redemption of Stock.  Whenever the Company shall be permitted
                  -------------------                                          
and shall elect to redeem shares of Stock in accordance with the provisions of
the Certificate, it shall (unless otherwise agreed to in writing with the
Depositary) give or cause notice to be given to the Depositary not less than 30
days, but not more than 60 days, prior to the date of such proposed redemption
of Stock and of the number of such shares held by the Depositary to be so
redeemed and the applicable redemption price, as set forth in the Certificate,
which notice shall be accompanied by a certificate from the Company stating that
such redemption of Stock is in accordance with the provisions of the
Certificate.  On the date of such redemption, if the Company shall then have
paid or caused to be paid in full to the Depositary the redemption price of the
Stock to be redeemed, plus an amount equal to any accrued and unpaid dividends
thereon to the date fixed for redemption, in accordance with the provisions of
the Certificate, the Depositary shall redeem the number of Depositary Shares
representing such

                                       8
<PAGE>
 
Stock.  The Depositary shall mail notice of the Company's redemption of Stock
and the proposed simultaneous redemption of the number of Depositary Shares
representing the Stock to be redeemed by first-class mail, postage prepaid, not
less than 20 days, but not more than 50 days, prior to the date fixed for
redemption of such Stock and Depositary Shares (the "Redemption Date") to the
record holders of the Receipts evidencing the Depositary Shares to be so
redeemed, at the address of such holders as they appear on the records of the
Depositary; but neither failure to mail any such notice of redemption of Deposi-
tary Shares to one or more such holders nor any defect in any notice of
redemption of Depositary Shares to one or more such holders shall affect the
sufficiency of the proceedings for redemption as to the other holders.  The
Company shall provide the Depositary with the information necessary for the
Depositary to prepare such notice and each such notice shall state: (i) the
Redemption Date, (ii) the number of Depositary Shares to be redeemed and, if
less than all the Depositary Shares held by any such holder are to be redeemed,
the number of such Depositary Shares held by such holder to be so redeemed,
(iii) the redemption price, (iv) the place or places where Receipts evidencing
Depositary Shares are to be surrendered for payment of the redemption price, and
(v) that dividends in respect of the Stock represented by the Depositary Shares
to be redeemed shall cease to accrue on such Redemption Date.  If less than all
the outstanding Depositary Shares are to be redeemed, the Depositary Shares to
be so redeemed shall be selected by the Depositary by lot or pro rata (as nearly
as may be) or by any other method, in each case, as determined by the Depositary
in its sole discretion to be equitable.

     Notice having been mailed by the Depositary as aforesaid, from and after
the Redemption Date (unless the Company shall have failed to provide the funds
necessary to redeem the Stock evidenced by the Depositary Shares called for
redemption) (i) dividends on the shares of Stock so called for redemption shall
cease to accrue from and after such date, (ii) the Depositary Shares being
redeemed from such proceeds shall be deemed no longer to be outstanding, (iii)
all rights of the holders of Receipts evidencing such Depositary Shares (except
the right to receive the redemption price) shall, to the extent of such
Depositary Shares, cease and terminate, and (iv) upon surrender in accordance
with such redemp-

                                       9
<PAGE>
 
tion notice of the Receipts evidencing any such Depositary Shares called for
redemption (properly endorsed or assigned for transfer, if the Depositary or
applicable law shall so require), such Depositary Shares shall be redeemed by
the Depositary at a redemption price per Depositary Share equal to one one-
thousandth (1/1,000) of the redemption price per share paid with respect to the
shares of Stock plus all money and other property, if any, represented by such
Depositary Shares, including all amounts paid by the Company in respect of
dividends that on the Redemption Date have accumulated on the shares of Stock to
be so redeemed and have not theretofore been paid.

     If fewer than all of the Depositary Shares evidenced by a Receipt are
called for redemption, the Depositary shall deliver to the holder of such
Receipt upon its surrender to the Depositary, together with the redemption
payment, a new Receipt evidencing the Depositary Shares evidenced by such prior
Receipt and not called for redemption.

                                 ARTICLE III

                           CERTAIN OBLIGATIONS OF
                     HOLDERS OF RECEIPTS AND THE COMPANY

     SECTION 3.1  Filing Proofs, Certificates and Other Information.  Any holder
                  -------------------------------------------------             
of a Receipt may be required from time to time to file such proof of residence,
or other matters or other information, to execute such certificates and to make
such representations and warranties as the Depositary or the Company may
reasonably deem necessary or proper.  The Depositary or the Company may withhold
the delivery, or delay the registration of transfer, redemption or exchange, of
any Receipt or the withdrawal or conversion of the Stock represented by the
Depositary Shares evidenced by any Receipt or the distribution of any dividend
or other distribution or the sale of any rights or of the proceeds thereof until
such proof or other information is filed or such certificates are executed or
such representations and warranties are made.

     SECTION 3.2  Payment of Taxes or Other Governmental Charges.  Holders of
                  ----------------------------------------------             
Receipts shall be obligated to make payments to the Depositary of certain
charges and expenses, as provided in Section 5.7.  Registration of

                                       10
<PAGE>
 
transfer of any Receipt or any withdrawal of Stock and all money or other
property, if any, represented by the Depositary Shares evidenced by such Receipt
may be refused until any such payment due is made, and any dividends or other
distributions may be withheld or any part of or all the Stock or other property
represented by the Depositary Shares evidenced by such Receipt and not
theretofore sold may be sold for the account of the holder thereof (after
attempting by reasonable means to notify such holder prior to such sale), and
such dividends or other distributions or the proceeds of any such sale may be
applied to any payment of such charges or expenses, the holder of such Receipt
remaining liable for any deficiency.

     SECTION 3.3  Warranty as to Stock.  The Company hereby represents and
                  --------------------                                    
warrants that the Stock, when issued, shall be duly authorized, validly issued,
fully paid and nonassessable.  Such representation and warranty shall survive
the deposit of the Stock and the issuance of Receipts.

                      THE DEPOSITED SECURITIES; NOTICES

     SECTION 4.1  Cash Distributions.  Whenever the Depositary shall receive any
                  ------------------                                            
cash dividend or other cash distribution on Stock, the Depositary shall, subject
to Section 3.1 and 3.2, distribute to record holders of Receipts on the record
date fixed pursuant to Section 4.4 such amounts of such dividend or distribution
as are, as nearly as practicable, in proportion to the respective numbers of
Depositary Shares evidenced by the Receipts held by such holders; provided that,
                                                                  --------      
if the Company or the Depositary shall be required to withhold and shall
withhold from any cash dividend or other cash distribution in respect of the
Stock an amount on account of taxes or as otherwise required by law, regulation
or court process, the amount made available for distribution or distributed in
respect of Depositary Shares shall be reduced accordingly.  If the calculation
of any such cash dividend or other cash distribution to be paid to any record
holder on the aggregate number of Receipts held by such holder results in an
amount that is a fraction of a cent, the amount the Depositary shall distribute
to such

                                       11
<PAGE>
 
record holder shall be rounded to the next highest whole cent, and upon request
of the Depositary, the Company shall pay the additional amount to the Depositary
for distribution.

     SECTION 4.2  Distributions Other than Cash, Rights, Preferences or
                  -----------------------------------------------------
Privileges.  Whenever the Depositary shall receive any distribution other than
- ----------                                                                     
cash, rights, preferences or privileges upon the Stock, the Depositary shall,
subject to Sections 3.1 and 3.2, distribute to record holders of Receipts on
the record date fixed pursuant to Section 4.4 such amounts of the securities or
property received by it as are, as nearly as practicable, in proportion to the
respective numbers of Depositary Shares evidenced by the Receipts held by such
holders, in any manner that the Depositary may deem equitable and practicable
for accomplishing such distribution.  If in the opinion of the Depositary such
distribution cannot be made proportionately among such record holders, or if
for any other reason (including any requirement that the Company or the
Depositary withhold an amount on account of taxes) the Depositary deems such
distribution not to be feasible, the Depositary may adopt such method as it
deems equitable and practicable for the purpose of effecting such distribution,
including the sale (at public or private sale) of the securities or property
thus received, or any part thereof, at such place or places and upon such terms
as it may deem proper.  The net proceeds of any such sale shall, subject to
Sections 3.1 and 3.2, be distributed or made available for distribution, as the
case may be, by the Depositary to record holders of Receipts as provided by
Section 4.1 in the case of a distribution received in cash.

     SECTION 4.3  Subscription Rights, Preferences or Privileges.  If the
                  ----------------------------------------------         
Company shall at any time offer or cause to be offered to the persons in whose
names Stock is recorded on the books of the Company any rights, preferences or
privileges to subscribe for or to purchase any securities or any rights,
preferences or privileges of any other nature, such rights, preferences or
privileges shall in each such instance be made available by the Depositary to
the record holders of Receipts in such manner as the Depositary may determine,
either by the issuance to such record holders of warrants representing such
rights, preferences or privileges or by such other method as may be approved by
the Depositary in its dis-

                                       12
<PAGE>
 
cretion with the approval of the Company; provided that, (i) if at the time of
                                          --------                            
issue or offer of any such rights, preferences or privileges the Depositary
determines that it is not lawful or (after consultation with the Company) not
feasible to make such rights, preferences or privileges available to holders of
Receipts by the issue of warrants or otherwise or (ii) if and to the extent so
instructed by holders of Receipts who do not desire to exercise such rights,
preferences or privileges, then the Depositary, in its discretion (with approval
of the Company, if the Depositary has determined that it is not feasible to make
such rights, preferences or privileges available), may, if applicable laws or
the terms of such rights, preferences or privileges so permit, sell such rights,
preferences or privileges at public or private sale, at such place or places and
upon such terms as it may deem proper.  The net proceeds of any such sale shall,
subject to Sections 3.1 and 3.2, be distributed by the Depositary to the record
holders of Receipts entitled thereto as provided by Section 4.1 in the case of a
distribution received in cash.

     If the securities to which such rights, preferences or privileges relate
must be registered under the Securities Act in order to be offered or sold to
holders of Receipts, the Company shall file a registration statement under the
Securities Act with respect to such rights, preferences or privileges and
securities promptly and shall use its best efforts and take all steps available
to it to cause such registration statement to become effective sufficiently in
advance of the expiration of such rights, preferences or privileges to enable
such holders to exercise such rights, preferences or privileges.  In no event
shall the Depositary make available to the holders of Receipts any right,
preference or privilege to subscribe for or to purchase any securities unless
and until it has received written notice from the Company that such registration
statement has become effective or that the offer and sale of such securities to
such holders are exempt from registration under the Securities Act and the
Company shall have provided to the Depositary an opinion of counsel to such
effect.

     If any other action under the laws of any jurisdiction or any governmental
or administrative authorization, consent or permit is required to permit such
rights, preferences or privileges to be made available to

                                       13
<PAGE>
 
holders of Receipts, the Company shall use its reasonable best efforts to take
such action or obtain such authorization, consent or permit sufficiently in
advance of the expiration of such rights, preferences or privileges to enable
such holders to exercise such rights, preferences or privileges.

     SECTION 4.4  Notice of Dividends, etc.; Fixing Record Date for Holders of
                  ------------------------------------------------------------
Receipts.  Whenever any cash dividend or other cash distribution shall become
- --------                                                                     
payable or any distribution other than cash shall be made, or if rights,
preferences or privileges shall at any time be offered, with respect to the
Stock, or whenever the Depositary shall receive notice of any meeting at which
holders of Stock are entitled to vote or of which holders of Stock are entitled
to notice, or whenever the Depositary and the Company shall decide that it is
appropriate, the Depositary shall in each such instance fix a record date (which
shall be the same date as the record date fixed by the Company with respect to
or otherwise in accordance with the terms of the Stock) for determining which
holders of Receipts shall be entitled to receive such dividend, distribution,
rights, preferences or privileges or the net proceeds of the sale thereof, or to
give instructions for the exercise of voting rights at any such meeting, or
shall be entitled to notice of such meeting or for any other appropriate
reasons.

     SECTION 4.5  Voting Rights.  Upon receipt of notice of any meeting at which
                  -------------                                                 
the holders of Stock are entitled to vote, the Depositary shall, as soon as
practicable thereafter, mail to the record holders of Receipts a notice that
shall contain (i) such information as is contained in such notice of meeting and
(ii) a statement that the holders may, subject to any applicable restrictions,
instruct the Depositary as to the exercise of the voting rights pertaining to
the amount of Stock represented by their respective Depositary Shares (in-
cluding an express indication that instructions may be given to the Depositary
to give a discretionary proxy to a person designated by the Company) and a brief
statement as to the manner in which such instructions may be given.  Upon the
written request of the holders of Receipts on the relevant record date, the
Depositary shall endeavor insofar as practicable to cast or cause to be cast, in
accordance with the instructions set forth in such requests, the number of
votes in respect of the Stock

                                       14
<PAGE>
 
represented by the Depositary Shares evidenced by Receipts as to which voting
instructions are received.  The Company hereby agrees to take all reasonable
action that may be deemed necessary by the Depositary to enable the Depositary
to cast such votes or cause such votes to be cast.  In the absence of
instructions from the holder of a Receipt, the Depositary shall not cast any
vote (but, at its discretion, may appear at any meeting with respect to such
Stock unless directed to the contrary by the holders of all the Receipts) in
respect of the Stock represented by the Depositary Shares evidenced by such
Receipt.

     SECTION 4.6  Changes Affecting Deposited Securities and Reclassifications,
                  -------------------------------------------------------------
Recapitalizations, etc.  Upon any change in par or stated value or liquidation
- ----------------------                                                        
preference, split-up, combination or any other reclassification of the Stock,
or upon any recapitalization, reorganization, merger or consolidation affecting
the Company or to which it is a party, the Depositary may in its discretion with
the approval of, and shall upon the instructions of, the Company, and (in either
case) in such manner as the Depositary may deem equitable, (i) make such
adjustments as are certified by the Company in the fraction of an interest
represented by one Depositary Share in one share of Stock as may be necessary
fully to reflect the effects of such change in par or stated value or
liquidation preference, split-up, combination or other reclassification of the
Stock, or of such recapitalization, reorganization, merger or consolidation,
and (ii) treat any securities that shall be received by the Depositary in
exchange for or upon conversion of or in respect of the Stock as new deposited
securities so received in exchange for or upon conversion or in respect of such
Stock.  In any such case the Depositary may in its discretion, with the
approval of the Company, execute and deliver additional Receipts or may call for
the surrender of all outstanding Receipts to be exchanged for new Receipts
specifically describing such new deposited securities.  Anything to the contrary
herein notwithstanding, holders of Receipts shall have the right from and after
the effective date of any such change in par or stated value or liquidation
preference, split-up, combination or other reclassification of the Stock or any
such recapitalization, reorganization, merger or consolidation to surrender such
Receipts to the Depositary with instructions to convert, exchange or surrender
the Stock

                                       15
<PAGE>
 
represented thereby only into or for, as the case may be, the kind and amount of
shares of stock and other securities and property and cash into which the Stock
represented by such Receipts might have been converted or for which such Stock
might have been exchanged or surrendered immediately prior to the effective date
of such transaction.

     SECTION 4.7  Delivery of Reports.  The Depositary shall furnish to holders
                  -------------------                                           
of Receipts any reports and communications received from the Company that are
received by the Depositary as the holder of Stock.

     SECTION 4.8  List of Receipt Holders.  Promptly upon request from time to
                  -----------------------                                     
time by the Company, the Depositary shall furnish to it a list, as of the most
recent practicable date, of the names, addresses and holdings of Depositary
Shares of all record holders of Receipts.  The Company shall be entitled to
receive such list twice annually without charge.


                                  ARTICLE V

                      THE DEPOSITARY, THE DEPOSITARY'S
                    AGENTS, THE REGISTRAR AND THE COMPANY

     SECTION 5.1  Maintenance of Offices, Agencies and Transfer Books by the
                  ----------------------------------------------------------
Depositary; Registrar.  Upon execution of this Deposit Agreement, the Depositary
- ---------------------                                                           
shall maintain at the Depositary's Office, facilities for the execution and
delivery, registration and registration of transfer, surrender and exchange of
Receipts, and at the offices of the Depositary's Agents, if any, facilities for
the delivery, registration of transfer, surrender and exchange of Receipts, all
in accordance with the provisions of this Deposit Agreement.

     The Depositary shall keep books at the Depositary's Office for the
registration and registration of transfer of Receipts, which books during normal
business hours shall be open for inspection by the record holders of Receipts,
provided that any such holder requesting to exercise such right shall certify
- --------                                                                      
to the Depositary that such inspection shall be for a proper purpose reasonably
related to such person's interest as an owner of Depositary Shares evidenced by
the Receipts.

                                       16
<PAGE>
 
     The Depositary may close such books, at any time or from time to time,
when deemed necessary or appropriate by it in connection with the performance
of its duties hereunder.

     The Depositary may, with the approval of the Company, appoint a Registrar
for registration of the Receipts or the Depositary Shares evidenced thereby.
If the Receipts or the Depositary Shares evidenced thereby or the Stock
represented by such Depositary Shares shall be listed on one or more national
stock exchanges, the Depositary shall appoint a Registrar (acceptable to the
Company) for registration of such Receipts or Depositary Shares in accordance
with any requirements of such exchange. Such Registrar (which may be the
Depositary if so permitted by the requirements of any such exchange) may be
removed and a substitute registrar appointed by the Depositary upon the
request or with the approval of the Company. If the Receipts, such Depositary
Shares or such Stock are listed on one or more other stock exchanges, the
Depositary shall, at the request and at the expense of the Company, arrange
such facilities for the delivery, registration, registration of transfer,
surrender and exchange of such Receipts, such Depositary Shares or such Stock
as may be required by law or applicable stock exchange regulation.

     The Depositary may from time to time appoint Depositary's Agents to act
in any respect for the Depositary for the purposes of this Deposit Agreement
and may at any time appoint additional Depositary's Agents and vary or
terminate the appointment of such Depositary's Agents. The Depositary shall
notify the Company of any such action.

     SECTION 5.2  Prevention of or Delay in Performance by the Depositary, the
                  ------------------------------------------------------------
Depositary's Agents, the Registrar or the Company.  Neither the Depositary nor
- -------------------------------------------------                             
any Depositary's Agent nor the Registrar nor the Company shall incur any
liability to any holder of any Receipt if by reason of any provision of any
present or future law, or regulation thereunder, of the United States of
America or of any other governmental authority or, in the case of the
Depositary, the Depositary's Agent or the Registrar, by reason of any
provision, present or future, of the Certificate or by reason of any act of
God or war or other circumstance beyond the reasonable control of the relevant
party, the Depositary, the Depositary's Agent,

                                       17
<PAGE>
 
the Registrar or the Company shall be prevented, delayed or forbidden from, or
subjected to any penalty on account of, doing or performing any act or thing
that the terms of this Deposit Agreement provide shall be done or performed,
nor shall the Depositary, any Depositary's Agent, the Registrar or the Company
incur liability to any holder of a Receipt (i) by reason of any nonperformance
or delay, caused as aforesaid, in the performance of any act or thing that the
terms of this Deposit Agreement shall provide shall or may be done or
performed or (ii) by reason of any exercise of, or failure to exercise, any
discretion provided for in this Deposit Agreement except, in the case of any
such exercise or failure to exercise discretion not caused as aforesaid, if
caused by the gross negligence, willful misconduct or bad faith of the party
charged with such exercise or failure to exercise.

     SECTION 5.3  Obligation of the Depositary, the Depositary's Agents, the
                  ----------------------------------------------------------
Registrar and the Company.  Neither the Depositary nor any Depositary's Agent
- -------------------------                                                    
nor the Registrar nor the Company assumes any obligation or shall be subject to
any liability under this Deposit Agreement or any Receipt to holders of Receipts
other than for its gross negligence, willful misconduct or bad faith.

     Neither the Depositary nor any Depositary's Agent nor the Registrar nor the
Company shall be under any obligation to appear in, prosecute or defend any
action, suit or other proceeding in respect of the Stock, the Depositary
Shares or the Receipts that in its opinion may involve it in expense or
liability unless indemnity satisfactory to it against all expense and
liability be furnished as often as may be required.

     Neither the Depositary nor any Depositary's Agent nor the Registrar nor the
Company shall be liable for any action or any failure to act by it in reliance
upon the written advice of legal counsel or accountants, or information from
any person presenting Stock for deposit, any holder of a Receipt or any other
person believed by it in good faith to be competent to give such information.
The Depositary, any Depositary's Agent, the Registrar and the Company may each
rely and shall each be protected in acting upon any written notice, request,
direction or other document believed by it to be genuine and to have been
signed or presented by the proper party or parties.

                                       18
<PAGE>
 
     The Depositary shall not be responsible for any failure to carry out any
instruction to vote any of the shares of Stock or for the manner or effect of
any such vote made, as long as any such action or non-action is in good faith.
The Depositary undertakes, and any Registrar shall be required to undertake,
to perform such duties and only such duties as are specifically set forth in
this Agreement, and no implied covenants or obligations shall be read into
this Agreement against the Depositary or any Registrar. The Depositary shall
indemnify the Company and hold it harmless from any loss, liability or expense
(including the reasonable costs and expenses of defending itself) that may
arise out of acts performed or omitted by the Depositary, including when such
Depositary acts as Registrar, or the Depositary's Agents in connection with
this Agreement due to its or their gross negligence, willful misconduct or bad
faith. The indemnification obligations of the Depositary set forth in this
Section 5.3 shall survive any termination of this Agreement and any succession
of any Depositary.

     The Depositary, its parent, affiliates and subsidiaries, the Depositary's
Agents, and the Registrar may own, buy, sell and deal in any class of
securities of the Company and its affiliates and in Receipts or Depositary
Shares or become pecuniarily interested in any transaction in which the
Company or its affiliates may be interested or contract with or lend money to
or otherwise act as fully or as freely as if it were not the Depositary, its
parent, affiliate or subsidiary or the Depositary's Agent or the Registrar
hereunder. The Depositary may also act as trustee, transfer agent or registrar
of any of the securities of the Company and its affiliates.

     It is intended that none of the Depositary, any Depositary's Agent or the
Registrar, acting as the Depositary, the Depositary's Agent or the Registrar,
as the case may be, shall be deemed to be an "issuer" of the securities under
the federal securities laws or applicable state securities laws, it being
expressly understood and agreed that the Depositary, any Depositary's Agent
and the Registrar are acting only in a ministerial capacity as Depositary or
Registrar for the Stock.

     Neither the Depositary (or its officers, directors, employees or agents)
nor any Depositary's Agent nor

                                       19

all sums due it and on the written request of the Company, shall execute and

such predecessor hereunder, shall duly assign, transfer and deliver all right,
title and interest in the Stock and any moneys or property held hereunder to
such successor and shall deliver to such successor a list of the record

     Any corporation into or with which the Depositary may be merged,
consolidated or converted shall be the successor of such Depositary without
the execution or filing of any document or any further act, and notice thereof
shall not be required hereunder. Such successor Depositary may authenticate
the Receipts in the name of the predecessor Depositary or in the name of the
successor Depositary.

performed or omitted in connection with this Agreement and the Receipts by
the Depositary, any Registrar or any of their respective agents (including any
Depositary's Agent), except for any liability arising out of negligence,

persons. The obligations of the Company set forth in this Section 5.6 shall

depositary arrangements provided for herein. The Company shall pay all charges
of the Depositary in connection with the initial deposit of the Stock and the
initial issuance of the Depositary Shares, all withdrawals of shares of the
Stock by owners of Depositary Shares, and any redemption or exchange of the
Stock at the option of the Company. All other transfer and other taxes and
governmental charges shall be at the expense of holders of Depositary Shares.
If, at the request of a holder of Receipts, the Depositary incurs charges or
expenses for which it is not otherwise liable hereunder, such holder shall be
liable for such charges and expenses. All other charges and expenses of the
Depositary and any Depositary's Agent hereunder (including, in each case,
reasonable fees and expenses of counsel) incident to the performance of their
respective obligations hereunder shall be paid upon prior consultation and
agreement between the Depositary and the Company as to the amount and nature

imposed by applicable tax laws, regulations or administrative practice with

with respect to the application of such requirements to particular payments or
holders or in other particular circumstances and may for purposes of this
Agreement rely on any such direction in accordance with the provisions of
Section 5.3 hereof.

     The Depositary shall maintain all appropriate records documenting
compliance with such requirements and shall make such records available on
request to the Company or to its authorized representatives.

redeemed pursuant to Section 2.8 or (ii) there shall have been made a final
distribution in respect of the Stock in connection with any liquidation,
dissolution or winding up of the Company and such distribution shall have been
distributed to the holders of Receipts pursuant to Sections 4.1 or 4.2, as

this Deposit Agreement, the Depositary thereafter shall discontinue the transfer
of Receipts, shall suspend the distribution of dividends to the holders thereof
and shall not give any further notices (other than notice of such termination)
or perform any further acts under this Deposit Agreement, except that the
Depositary shall continue to collect dividends and other distributions
pertaining to the Stock, shall sell rights, preferences or privileges as
provided in this Deposit Agreement and shall continue to deliver the Stock and
any money and other property represented by Receipts upon surrender thereof by
the holders thereof.  At any time after the expiration of two years from the
date of termination, the Depositary may sell Stock then held hereunder at public
or private sale, at such places and upon such terms as it deems proper and may
thereafter hold the net proceeds of any such sale, together with any money and
other property held by it hereunder, without liability for interest, for the
benefit, pro rata in accordance with their holdings, of the holders of Receipts
that have not theretofore been surrendered.  After making such sale, the
Depositary shall be discharged from all obligations under this Deposit Agreement
except to account for such net proceeds and money and other property.

     Upon the termination of this Deposit Agreement, the Company shall be
discharged from all obligations under this Deposit Agreement except for its
obligations to the Depositary, the Registrar and any Depositary's Agent under
Sections 5.6 and 5.7.

May 20, 1994



Board of Directors
UAL Corporation
1200 East Algonquin Road
Elk Grove Township, IL 60007


Gentlemen and Madam:

You have requested our opinion as to the fairness, from a financial point of
view, to the holders (the "Common Stockholders") of shares of common stock, par
value $5.00 per share ("Old Shares"), of UAL Corporation, a Delaware corporation
("UAL"), of the consideration to be received by such Common Stockholders in
connection with the proposed recapitalization of UAL (the "Transaction"), as set
forth in, and pursuant to the terms of, the Agreement and Plan of
Recapitalization dated as of March 25, 1994, as proposed to be amended and
restated (the "Recapitalization Agreement"), among UAL and the Airline Pilots
Association, International, and the International Association of Machinists and
Aerospace Workers (together with other participating employees, the
"Participating Employees").

We understand that the Transaction, as more specifically set forth in the
Recapitalization Agreement, provides that, in exchange for certain labor
concessions by the Participating Employees, UAL will issue common stock to
certain employee trusts/ESOPs equal to a minimum of 55% and a maximum of 63% of
the common stock of UAL.  We also understand that in the Transaction the current
Common Stockholders of UAL will receive, for each Old Share held, one-half of a
new share of common stock, par value $.01 per share, of UAL (representing an
equity interest immediately after the Transaction is completed of approximately
45% of one Old Share's current percentage equity interest in UAL, subject to
possible reduction) and one-thousandth of a share of redeemable preferred stock
of UAL, which will be redeemed immediately after issuance for $25.80 in cash,
$15.55 face amount of Series A Debentures due 2004 ("Series A Debentures") of
United Air Lines, Inc. ("United") and $15.55 face amount of Series B Debentures
due 2014 ("Series B Debentures"; together with the Series A Debentures, the
"Debentures") of United and Depositary Preferred Shares ("Depositary Preferred
Shares") representing $31.10 liquidation preference of Series B Preferred Stock,
without par value, of UAL ("Series B Preferred Stock").  The Depositary
Preferred Shares, the Series A Debentures and the Series B Debentures are
referred to herein as the "Securities".

We also understand that United intends to offer for sale in a public offering $
principal amount of the Series A Debentures and $       principal amount of the
Series B Debentures (the "United Debt Offering") and that UAL intends to offer
for sale in a public offering         Depositary Preferred Shares (the "UAL
Preferred Offering" and, together with the United Debt Offering, the
"Offerings").  If the Offerings are consummated, the current Common Stockholders
of UAL will receive, for each Old Share held, in lieu of the Securities
described in the preceding paragraph, (a) the gross proceeds from the sale by
United of $15.55 principal amount of the Series A Debentures and $15.55
principal amount of the Series B Debentures pursuant to the United Debt Offering
and (b) the gross proceeds from the sale by UAL of Depositary Preferred
<PAGE>
 
                                                                             2

Shares representing $31.10 liquidation preference of its Series B Preferred
Stock.  As described below, the principal amounts of the Debentures and the
liquidation preference of the Series B Preferred Stock could be reduced if the
Offerings are consummated and the interest rates or dividend rate, as the case
may be, on such Securities were to exceed certain limitations contained in the
Recapitalization Agreement.

In arriving at our opinion, we have reviewed and analyzed the Recapitalization
Agreement, as well as certain publicly available business and financial
information relating to UAL.  We have also reviewed certain other information,
including financial forecasts provided to us by UAL.  We have met with UAL's
management to discuss the past and current operations and financial condition
and prospects of UAL.  We have also considered certain financial and stock
market data for UAL and we have compared that data with similar data for other
publicly held companies in businesses similar to those of UAL, and we have
considered the financial terms of certain other business combinations that have
recently been effected.  We also considered such other information, financial
studies, analyses and investigations and financial, economic and market criteria
that we deemed relevant.  In addition, we have reviewed the alternative of not
effecting a reorganization or similar transaction and UAL implementing various
operating strategies considered by it which, if fully implemented, might result
in a greater value to Common Stockholders than the Transaction; however, we
understand and have assumed for purposes of this opinion that the Board of
Directors of UAL has determined, in light of various factors relating to the
implementation of such operating strategies and the availability of the
Transaction, not to pursue such implementation.

In connection with our review, we have not independently verified any of the
foregoing information and have relied on its being complete and accurate in all
material respects.  With respect to the financial forecasts, we have assumed
that they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of UAL's management as to the future financial
performance of UAL.  We express no view as to such forecasts or the assumptions
on which they are based.  We have not made an independent evaluation or
appraisal of the assets or liabilities of UAL, nor have we been furnished with
any such appraisals.  We were not requested to, and did not, solicit third party
offers to acquire all or any part of UAL, nor, to our knowledge, has any
interest in making such an offer been presented by any third party, including in
response to the public disclosure regarding discussions between UAL and the
Participating Employees.  We have assumed that the results expected by UAL's
management to be obtained from the Transaction, including those arising from the
Participating Employees' labor concessions, will be realized.  Our opinion is
necessarily based solely upon information available to us and business, market,
economic and other conditions as they exist on, and can be evaluated as of, the
date hereof.  Our opinion does not address UAL's underlying business decision to
effect the Transaction.

Pursuant to the Recapitalization Agreement, the interest and dividend rates for
the Securities were initially set upon the execution of the Recapitalization
Agreement.  The interest or dividend rate on each such Security will be reset,
as of a date to be determined that is not fewer than five calendar days and not
greater than ten calendar days prior to the meeting of the Common Stockholders
of UAL at which the Transaction will be voted upon, to the rate required to
cause
<PAGE>
 
                                                                             3

each such security to trade at 100% of its aggregate principal amount (in the
case of the Debentures) or at 100% of its aggregate liquidation preference (in
the case of the Series B Preferred Stock) (collectively, "par"), on a fully
distributed basis, as of such date, subject to a limitation specified in the
Recapitalization Agreement on the amount that such rates can increase.  If the
Offerings are not consummated, our opinion is based on such final rates being
set so that the Securities would trade, as of such date, on a fully distributed
basis, at par.  It should be noted that our opinion does not purport to
represent any  view as to what the trading value of the Securities actually will
be when the Securities are issued to the Common Stockholders following
consummation of the Transaction.  The actual trading value of such Securities
could be higher or lower depending upon changes in interest rates, dividend
rates, market conditions, general economic conditions and other factors that
generally influence the price of securities.  Because of the large aggregate
amount of Securities that would be issued to Common Stockholders of UAL if the
Offerings are not consummated and other factors, such Securities may trade
initially, and for an extended period thereafter, at prices below those at which
they would trade on a fully distributed basis.  Furthermore, any valuation of
securities is only an approximation, subject to uncertainties and contingencies
all of which are difficult to predict and beyond our control.

If the Offerings are consummated, the interest rates on the Debentures and the
dividend rate on the Series B Preferred Stock may be set at rates that are in
excess of the limitation contained in the Recapitalization Agreement, in which
event the principal amount of the series of Debentures affected or the number of
Depositary Preferred Shares, as the case may be, will be reduced so that the
aggregate amount of interest payable by United or dividends payable by UAL, as
the case may be, with respect to such Security will not exceed amounts specified
in the Recapitalization Agreement, and the amount of the proceeds from the sale
of such Securities to be received by the current Common Stockholders of UAL in
respect of each Old Share will be reduced accordingly.  In addition, in certain
other circumstances, such proceeds could be less than the stated face amount or
liquidation preference of the Securities. Our opinion is based on the
assumption that, if the Offerings are consummated, the proceeds of the
Debentures and the Depositary Preferred Shares to be received by the current
Common Stockholders of UAL in respect of each Old Share will not be less than
the principal amounts of the Debentures and the number of Depositary Preferred
Shares that would have been distributed to such Common Stockholders of UAL had
the Offerings not been consummated.

We have acted as financial advisor to UAL in connection with the Transaction and
will receive a fee for our services, a significant portion of which is
contingent upon the consummation of the Transaction.  A portion of this fee
relates to the rendering of this opinion.

It is understood that this opinion is only for the information of the Board of
Directors of UAL.  However, this opinion may be included in its entirety in any
proxy statement from UAL to its Common Stockholders.  This opinion may not,
however, be summarized, excerpted from or otherwise publicly referred to without
our prior written consent, which will not unreasonably be withheld.  In
addition, we may not be otherwise publicly referred to without our prior
consent, which will not unreasonably be withheld.

Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the consideration to be received by the Common Stockholders of UAL in
the Transaction, taken as a whole, is fair to such Common Stockholders from a
financial point of view.


Very truly yours,

available estimates and judgments of UAL's management as to the future financial
performance of UAL.  We express no view as to such forecasts or the assumptions
on which they are based.  We have not made an independent evaluation or
appraisal of the assets or liabilities of UAL, nor have we been furnished with
any such appraisals.  We were not requested to, and did not, solicit third party
offers to acquire all or any part of UAL, nor, to our knowledge, has any
interest in making such an offer been presented by any third party, including in
response to the public disclosure regarding discussions between UAL and the
Participating Employees.  We have assumed that the results expected by UAL's
management to be obtained from the Transaction, including those arising from the
Participating Employees' labor concessions, will be realized.  Our opinion is
necessarily based solely upon information available to us and business, market,
economic and other conditions as they exist on, and can be evaluated as of, the
date hereof.  Our opinion does not address UAL's underlying business decision to
effect the Transaction.

Pursuant to the Recapitalization Agreement, the interest and dividend rates for
the Securities were initially set upon the execution of the Recapitalization
Agreement.  The interest or dividend rate on each such Security will be reset,
as of a date to be determined that is not fewer than five calendar days and not
greater than ten calendar days prior to the meeting of the Common Stockholders
of UAL at which the Transaction will be voted upon, to the rate required to
cause each such security to trade at 100% of its aggregate principal amount (in
the case of the Debentures) or at 100% of its aggregate liquidation preference
(in the case of the Series B Preferred Stock) (collectively, "par"), on a fully
distributed basis, as of such date, subject to a limitation specified in the
Recapitalization Agreement on the amount that such rates can increase.  If the
Offerings are not consummated, our opinion is based on such final rates being
set so that the Securities would trade, as of such date, on a fully distributed
basis, at par.  It should be noted that our opinion does not purport to
represent any  view as to what the trading value of the Securities actually will
be when the Securities are issued to the Common Stockholders following
consummation of the Transaction.  The actual trading value of such Securities
could be higher or lower depending upon changes in interest rates, dividend
rates, market conditions, general economic conditions and other factors that
generally influence the price of securities.  Because of the large aggregate
amount of Securities that would be issued to Common Stockholders of UAL if the
Offerings are not consummated and other factors, such Securities may trade
initially, and for an extended period thereafter, at prices below those at which
they would trade on a fully distributed basis.  Furthermore, any valuation of
securities is only an approximation, subject to uncertainties and contingencies
all of which are difficult to predict and beyond our control.

If the Offerings are consummated, the interest rates on the Debentures and the
dividend rate on the Series B Preferred Stock may be set at rates that are in
excess of the limitation contained in the Recapitalization Agreement, in which
event the principal amount of the series of Debentures affected or the number of
Depositary Preferred Shares, as the case may be, will be reduced so that the
aggregate amount of interest payable by United or dividends payable by UAL, as
the case may be, with respect to such Security will not exceed amounts specified
in the Recapitalization Agreement, and the amount of the proceeds from the sale
of such Securities to be received by the current Common Stockholders of UAL in
respect of each Old Share will be reduced accordingly.  In addition, in certain
other circumstances, such proceeds could be less than the stated face amount or
liquidation preference of the Securities.   Our opinion is based on the
assumption that, if the Offerings are consummated, the proceeds of the
Debentures and the Depositary Preferred Shares to be received by the current
Common Stockholders of UAL in respect of each Old Share will not be less than
the principal amounts of the Debentures and the number of Depositary Preferred
Shares that would have been distributed to such Common Stockholders of UAL had
the Offerings not been consummated.

We have acted as financial advisor to UAL in connection with the Transaction and
will receive a fee for our services, a significant portion of which is
contingent upon the consummation of the Transaction.  We will also receive a fee
for rendering this opinion and other additional services currently being
rendered to UAL.  In the ordinary course of our business, we actively trade the
debt and equity securities of UAL for our own account and for

the accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.

It is understood that this opinion is only for the information of the Board of
Directors of UAL.  However, this opinion may be included in its entirety in any
proxy statement from UAL to its Common Stockholders.  This opinion may not,
however, be summarized, excerpted from or otherwise publicly referred to without
our prior written consent, which will not unreasonably be withheld.  In
addition, we may not be otherwise publicly referred to without our prior
consent, which will not unreasonably be withheld.

Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the consideration to be received by the Common Stockholders of UAL in
the Transaction, taken as a whole, is fair to such Common Stockholders from a
financial point of view.


Very truly yours,
