ITEM 5.    Other Events

     On January 25, 1998, Northwest Airlines Corporation, a Delaware 
corporation ("Northwest"), Newbridge Parent Corporation, a Delaware 
corporation ("Newbridge"), Air Partners, L.P., a Texas limited partnership 
(the "Partnership"), the partners of the Partnership signatories thereto (the 
"Partners"), Bonderman Family Limited Partnership, a Texas limited 
partnership ("Transferor I"), 1992 Air, Inc., a Texas corporation 
("Transferor II"), and Air Saipan, Inc., a CNMI corporation ("Transferor III",
and collectively with "Transferor I" and "Transferor II", the "Transferors"), 
entered into an Investment Agreement (the "Investment Agreement").  Pursuant 
to the Investment Agreement and subject to the terms and conditions set forth 
therein, Northwest and Newbridge will acquire from the Partners the 
outstanding partnership interests in the Partnership and from the Transferors 
the shares of Class A Common Stock of Continental Airlines, Inc., a Delaware 
corporation ("Continental"), par value $.01 per share ("Continental Class A 
Common Stock"), owned by them, in exchange for shares of Class A Common 
Stock, par value $.01 per share, of Newbridge ("Newbridge Class A Common 
Stock") and cash at a ratio of 1.2079 shares of Newbridge Class A Common 
Stock or $60.82 in cash per share of Continental Class A Common Stock the 
beneficial ownership of which will be acquired by Northwest and Newbridge.

     The Partnership and the Transferors beneficially own 8,535,868 shares of 
Continental Class A Common Stock which represents approximately 14 percent of 
Continental's common stock equity and approximately 51 percent of its 
outstanding common stock voting power.  The aggregate consideration to be 
paid in the transaction is valued at approximately $519 million, expected to 
consist of approximately $311 million in cash and approximately 4.1 million 
shares of newly issued Newbridge Class A Common Stock.  After the transaction 
is completed, and assuming the completion of the repurchase of Northwest 
common stock owned by KLM Royal Dutch Airlines ("KLM") (as discussed below), 
approximately 4.5 percent of Northwest's outstanding stock will be held by an 
investment group managed by David Bonderman and James Coulter.

     In connection with the transactions contemplated by the Investment 
Agreement, Northwest and Newbridge have entered into a Governance Agreement 
(the "Governance Agreement") with Continental, dated as of January 25, 1998.  
The Governance Agreement contains certain agreements between Northwest, 
Newbridge and Continental regarding the control and management of Continental 
following the Closing, including restrictions on Northwest's and Newbridge's 
ability to acquire additional shares of Continental Common Stock and to vote 
the shares of Continental Common Stock owned by it and restrictions on 
Northwest's and Newbridge's ability to affect the composition and conduct of 
Continental's Board of Directors.

     Concurrently with the execution of the Investment Agreement, Northwest,
Newbridge and Newbridge Merger Sub, a Delaware corporation and a wholly owned
subsidiary of Newbridge ("Merger Sub"), entered into an Agreement and Plan of
Merger, dated as of January 25, 1998 (the "Merger Agreement"), providing for the
merger of Merger Sub with and into Northwest (the "Merger"), as a result of
which Northwest will become a wholly owned subsidiary of Newbridge and each
outstanding share of Class A Common Stock of Northwest, par value $.01 per
share, will be exchanged for one share of Newbridge Class A Common Stock. 
Following the Merger, Newbridge will change its name to "Northwest Airlines
Corporation" and Northwest will change its name to "Northwest Airlines Holding
Corporation."  The Merger will be accomplished without a vote of the
stockholders of Northwest in accordance with Section 251(g) under the Delaware
General Corporation Law.

                                                           Page 2 of 6 pages

     In addition, Northwest Airlines, Inc., an indirect wholly owned 
subsidiary of Northwest, and Continental have entered into an agreement 
providing for a global strategic operating alliance, dated as of January 25, 
1998 (the "Alliance Agreement").  The Alliance Agreement, when fully 
implemented, will connect the two carriers' networks and will include 
code-sharing, frequent flyer program reciprocity, cooperation between 
Continental and KLM, and other cooperative activities as well as offer 
consumers the benefits of greater scope, ease of ticketing, check-in and 
luggage handling.  Certain aspects of the Alliance Agreement are contingent 
on the successful conclusion of negotiations with Northwest's pilots' union.  
The two airlines have no plans to merge their operations and will retain 
separate boards, managements and headquarters.  No layoffs, mergers of 
workforces, transfers of flying or assets, or closures of facilities are 
planned.

     The closing of the transaction is subject to a number of customary
conditions, including approval under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, satisfactory review by the Department of
Transportation and the consummation of the Merger.  The transaction is expected
to close by the end of this year.

     In a previously announced transaction, Northwest and KLM have reached an 
agreement in principle to accelerate Northwest's repurchase of KLM's 
remaining 18,177,874 shares of Northwest common stock.  The total purchase 
price of approximately $775 million will be paid with a combination of senior 
unsecured notes in the aggregate principal amount of approximately $440 
million and cash in the amount of approximately $335 million.  The closing of 
the repurchase will occur no later than May 1, 1998 and is subject to the 
approval of the Northwest board of directors and the KLM supervisory board.  
Under certain limited circumstances, KLM will have an option to buy back from 
Northwest certain of the shares being repurchased by Northwest.

     Copies of the Investment Agreement, the Governance Agreement and the Merger
Agreement are attached hereto as Exhibits 2.1, 2.2 and 2.3 respectively.  The
foregoing descriptions of the Investment Agreement, the Governance Agreement and
the Merger Agreement are qualified in their entirety by reference to the full

          (b) Subject to adjustment in accordance with Section 2.3, Holdco Sub
shall issue to each Partner set forth on Schedule 2.2(b) (each a "SHARE ELECTING
PARTNER") in exchange for all of such Partner's Partnership Interests and to
each Transferor that elects to receive shares in exchange for all the shares of

share of Holdco Sub Class A Common Stock to such Share Electing Partner or

The shares of Holdco Sub Class A Common Stock to be issued to the Share Electing
Partners and the Transferors hereunder are referred to herein as the "EXCHANGE
SHARES".  

          (c) It is understood and agreed by the parties that Schedules 2.2(a)

2, 1998; PROVIDED that no more than 40% of the total exchange consideration,
valuing the Share Exchange Ratio at $60.82, received by the Partners and the
Transferors will consist of shares of Holdco Sub Class A Common Stock.

          2.3 ADJUSTMENTS TO CASH ELECTION SHARE PRICE AND EXCHANGE RATIO.

          (a) EXERCISE OF WARRANTS.  In the event the Closing shall not have
occurred prior to April 27, 1998 (or such later date on which the Warrants are
to expire) (the "WARRANT EXERCISE DATE"), the Partnership shall exercise the
Warrants in full prior to the close of business, New York City time, on such
date.  In the event the Closing shall occur prior to the Warrant Exercise Date,
the Partnership shall exercise the Warrants in full immediately prior to the
Closing.  The Partnership shall not be required to exercise the Warrants in
accordance with this Section 2.3(a) unless on or prior to the Warrant Exercise
Date or the Closing Date, as the case may be, it shall have received from Parent
or Holdco Sub immediately available funds in an amount equal to $28,356,015,
which is equal to the aggregate exercise price for the Warrants (the "AGGREGATE
EXERCISE PRICE"), or until immediately available funds in an amount equal to the
Aggregate Exercise Price have been transferred to the Company by Parent on
behalf of the Partnership.  The obligation of the Partnership to repay such
advance shall be evidenced by a note in the form of Exhibit E (the "NOTE"),
which note shall be secured by a pledge of the shares of Company Class A Common
Stock issued upon exercise of the Warrants in the form of Exhibit F (the
"PLEDGE").  The Partnership shall pay to Parent interest on the Aggregate
Exercise Price from (and including) the date on which the Aggregate Exercise
Price is advanced to (or on behalf of) the Partnership to (but excluding) the
date the Note (and such interest) is repaid.  Such interest, if any, and the
Aggregate Exercise Price shall be payable by the Partnership to Parent, without
offset, at the earlier to occur of (i) the Closing and (ii) the date this
Agreement is terminated in accordance with its terms (the "TERMINATION DATE"). 
Such interest shall accrue (A) for any period ending on or prior to July 25,
1998, at a rate equal to the sum of the "Applicable Eurodollar Margin" and the
"Eurodollar Rate" at the time in effect under the Credit Agreement, assuming a
30-day Interest Period (as defined in the Credit Agreement) (such interest rate
from time to time in effect, the "REVOLVING INTEREST RATE"; PROVIDED, HOWEVER,
that no amendment to the Credit Agreement shall have the effect of modifying the
Revolving Interest Rate hereunder) and (B) for 

<PAGE>

                                                                              7

any period from and including July 25, 1998, at a rate of 10% per annum.  If the
Closing occurs, the aggregate Cash Election Share Price payable and/or the
aggregate number of Exchange Shares to be delivered by Parent and Holdco Sub at
the Closing shall be reduced by the amount of principal and interest payable by
the Partnership under the Note (the "PAYOFF AMOUNT") in respect of each Partner
in proportion to each Partner's allocable share of the Payoff Amount, the
determination of the portion of the Payoff Amount allocable to the Cash Electing
Partners and the Share Electing Partners to be made by the Partnership and
notified to Parent in writing at least three Business Days in advance of the
Closing.  Any reduction in the Exchange Shares to be issued shall be based on
the average closing price for Parent Class A Common Stock as of the close of
business for each of the ten trading days ending on and including the third
Business Day preceding the Closing Date.

          (b) STOCK SPLITS, DIVIDENDS, ETC. In the event that, between the date
of this Agreement and the Closing, the outstanding shares of Parent Class A
Common Stock or Holdco Sub Class A Common Stock shall have been changed into a
different number of shares or a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares, the Share Exchange Ratio shall be correspondingly adjusted
to reflect such stock dividend, subdivision, reclassification, recapitalization,
split, combination or exchange of shares.

          2.4 CLOSING DATE. (a)  Unless this Agreement shall have been
terminated and the transactions herein contemplated shall have been abandoned
pursuant to Section 7.1(a) and subject to the satisfaction or waiver of the
conditions set forth in Article V, the closing (the "CLOSING") of the
transactions contemplated by Sections 2.1 and 2.2 will take place on the second
Business Day following satisfaction or waiver of the conditions set forth in
Article V, or at such other date and time as the parties shall otherwise
mutually agree, at the offices of Simpson Thacher & Bartlett, 425 Lexington
Avenue, New York, New York 10017 at 10:00 a.m., New York City time (the date on
which the Closing occurs (the "CLOSING DATE")).

          (b) At the Closing, the following actions shall occur:

             (i)    Parent or Holdco Sub shall pay or cause to be paid the
     aggregate Cash Election Share Price to or for the account of the Cash
     Electing Partners and Transferor III by wire transfer to such bank account
     (the "DESIGNATED BANK ACCOUNT") as the Partners' Representative shall
     designate in writing no later than two Business Days prior to the Closing
     Date;

            (ii)    At the effective time of the Merger, Holdco Sub shall issue
     shares of Holdco Sub Class A Common Stock to the Share Electing Partners
     and the Share Electing Transferors as directed by the Partners'
     Representative in writing no later than two Business Days prior to the
     Closing Date;

           (iii)    The parties shall execute and deliver, as applicable, (A)
     the Restated Partnership Agreement, (B) the Standstill Agreement and (C)
     the Registration Rights Agreement;

            (iv)    Each of the Partners and the Transferors shall deliver to
     Parent and Holdco Sub or their designee such documents as Parent and Holdco
     Sub may reasonably 

<PAGE>

                                                                              8

     request, including certificates for all shares of Company Class A Common
     Stock owned by the Partnership, to evidence the transfer to Parent and
     Holdco Sub or their designee of good and marketable title in and to all of
     the Partnership Interests being conveyed pursuant to this Agreement and the
     absence of any Liens or Restrictions on such shares of Company Class A
     Common Stock (other than any Lien or Restriction imposed pursuant to the
     terms of this Agreement), and all the shares of Company Class A Common
     Stock owned by the Transferors free and clear of any Lien or Restriction
     (other than any Lien or Restriction imposed pursuant to the terms of this
     Agreement); and

             (v)    Each party shall take such other actions, and shall execute
     and deliver such other instruments or documents, as shall be required under
     Article V.

          2.5 INTEREST PAYMENT.  In the event the Closing does not occur on or
prior to May 25, 1998 (the "INTEREST ACCRUAL DATE"), Parent shall pay to the
Partners and the Transferors at the Closing by wire transfer to the Designated
Bank Account a lump-sum cash amount equal to the interest accrued (a) at the
Revolving Interest Rate from (and including) the Interest Accrual Date to (but
excluding) the six month anniversary of the Interest Accrual Date and (b) at a
rate of 10% per annum from and including such six month anniversary to (but
excluding) the Closing Date, in each case on the aggregate cash (or cash
equivalent) value of the purchase price payable by Parent and Holdco Sub
hereunder (assuming for purpose of such calculation that all the Partners and
the Transferors are Cash Electing Partners).  Such interest shall be payable
only if the Closing occurs.

     Holdco Sub is duly organized, validly existing and in good standing under
     the laws of the State of Delaware and has the requisite corporate power and
     authority to carry on its business as now being conducted.  Each of Parent
     and Holdco Sub is duly qualified or licensed to do business and is in good
     standing in each jurisdiction in which the nature of its business or the
     ownership or leasing of its properties makes such qualification or
     licensing necessary, other than in such jurisdictions where the failure to
     be so qualified or licensed (individually or in the aggregate) could not
     reasonably be expected to have a material adverse effect with respect to
     Parent or Holdco Sub.  

          (b) CORPORATE AUTHORIZATION.  The execution, delivery and performance
     by Parent and Holdco Sub of this Agreement and the Registration Rights
     Agreement and the consummation by Parent and Holdco Sub of the transactions

     to applicable bankruptcy, insolvency, reorganization, moratorium,
     fraudulent transfer and other similar laws affecting creditors' rights
     generally from time to time in effect and to general principles of equity,
     including concepts of materiality, reasonableness, good faith and fair
     dealing, regardless of whether in a proceeding at equity or at law).  The
     shares of Holdco Sub Class A Common Stock issued to the Share Electing
     Partners and the Transferors pursuant to Section 2.2(b), when issued in
     accordance with the terms hereof, will be duly authorized, validly issued,
     fully paid and nonassessable and not subject to preemptive rights, and will
     be free and clear of any Lien or Restriction (other than any Lien or

     the Partnership Interests for its own account as principal for investment
     and not with a view to resale or distribution or with any present intention
     of distributing or selling the same.  Each of Parent and Holdco Sub is
     fully aware that such Partnership Interests have not been registered under
     the Securities Act or under any applicable state securities laws, and are
     being offered and sold in reliance on exemptions from the registration
     requirements of the Securities Act and all such laws.  Parent is and at the
     Closing Holdco Sub will be an "accredited investor" as such term is defined
     in Regulation D promulgated under the Securities Act.  Parent is and at the
     Closing Holdco Sub will be able to bear the economic risk of the investment

     Class B Common Stock issued and outstanding; (iii) 6,800,000 shares of
     Class A Common Stock held in the treasury of Parent;  (iv) 5,391,311 shares
     of Parent Class A Common Stock reserved for issuance upon exercise of stock
     options of Parent outstanding or which may be granted pursuant to employee
     stock option and similar plans; and (v) 10,435,231 shares of Parent Class A
     Common Stock reserved for issuance upon the conversion of Parent Class B
     Common Stock and Parent Series C Preferred Stock.  Except as described in
     the immediately preceding sentence and except for the preferred share
     purchase rights relating to the Parent Series D Preferred Stock, there are
     no securities of Parent or Holdco Sub (or their affiliates) currently
     outstanding that are convertible into or exercisable or exchangeable for
     shares of Parent Class A Common Stock. On the Closing Date, all outstanding
     shares of Parent's capital stock will be duly authorized, validly issued,
     fully paid and non-assessable.  

          (e) HOLDCO SUB CAPITALIZATION.  As of the date hereof, the authorized
     capital stock of Holdco Sub consists of 1,000 shares of Holdco Sub Class A
     Common Stock.  As of the close of business on January 23, 1998, there were
     1,000 shares of Holdco Sub Class A Common stock issued and outstanding. 
     Parent owns and, immediately prior to the Closing, Parent will own, of
     record and beneficially, 100% of the outstanding shares of Holdco Sub's
     capital stock, free and clear of all Liens and Restrictions other than
     those set forth in this Agreement and in the Merger Agreement.  As of the
     date hereof there are, and immediately prior to the Closing there will be,
     no warrants, options, rights, convertible securities or any other
     agreements, arrangements or commitments (other than this Agreement and the
     Merger Agreement) which obligate Parent or Holdco Sub to issue, sell or
     exchange any shares of Holdco Sub's capital stock to any Person (it being
     understood that at the effective time of the Merger, certain securities
     convertible into or exercisable or exchangeable for shares of Parent Common
     Stock will become convertible into shares of Holdco Sub Common Stock),
     other than shares of Parent Class A Common Stock, which are convertible
     into shares of Parent Class B Common Stock at any time on a one-for-one
     basis, and shares of Parent Class B Common Stock, which are convertible
     into shares of Parent Class A Common Stock at any time on a one-for-one
     basis.  The certificate of incorporation, by-laws and equity capital
     structure of Holdco Sub are, and at the Closing will be, identical in all
     material respects to those of Parent except as required by Section 251(g)
     of the DGCL.  The parties acknowledge that the capitalization of Holdco Sub
     will be modified in connection with the Merger as described in the Merger
     Agreement.  On the Closing Date, all outstanding shares of Holdco Sub's
     capital stock will be duly authorized, validly issued, fully paid and
     nonassessable.

          (f) NO CONFLICT.  Other than (i) the filing of a Form 3 and a Report
     on Schedule 13D under the Exchange Act, (ii) compliance with any applicable
     requirements of the HSR Act, (iii) compliance with any applicable
     requirements of the United States Department of Transportation (the "DOT")
     and the European Commission, (iv) listing the Exchange Shares for quotation
     on the NASDAQ National Market and (v) the filing of a certificate of merger
     with respect to the Merger with the Secretary of State of the State of
     Delaware and appropriate documents in other states where Parent is
     qualified to do business, no filing with, and no permit, authorization,
     consent or approval of, any Governmental Authority is necessary for the
     execution of this Agreement or the Registration Rights Agreement by Parent
     or Holdco Sub and the consummation by Parent and Holdco Sub of the
     transactions contemplated hereby and thereby, except for such 

<PAGE>

                                                                             11

     filings the failure of which to be made, individually or in the aggregate,
     could not reasonably be expected to have a material adverse effect on
     Parent, Holdco Sub and their subsidiaries, taken as a whole, or to prevent
     or materially delay the consummation of the transactions contemplated
     hereby and thereby.  Neither the execution and delivery of this Agreement
     or the Registration Rights Agreement by Parent or Holdco Sub nor the
     consummation by Parent or Holdco Sub of the transactions contemplated
     hereby or thereby, nor compliance by Parent or Holdco Sub with any of the
     provisions hereof or thereof (i) conflicts with or results in any breach of
     the charter or bylaws of Parent or Holdco Sub, (ii) contravenes, conflicts
     with or would constitute a violation of any provision of any law,
     regulation, judgment, injunction, order or decree binding upon Parent or
     Holdco Sub, or (iii) constitutes a default under or gives rise to any right
     of termination, cancellation or acceleration of any right or obligation of
     Parent or Holdco Sub or any of their respective subsidiaries or to a loss
     of any benefit to which Parent or Holdco Sub or any of their respective
     subsidiaries is entitled under any provision of any agreement, contract or
     other instrument binding on Parent or Holdco Sub or any of their respective
     subsidiaries or any license, franchise, permit or other similar
     authorization held by Parent or Holdco Sub or any of their respective
     subsidiaries, except, in the case of clauses (ii) and (iii), for any such
     contravention, conflict, violation, default, termination, cancellation,
     acceleration or loss that would not have a material adverse effect on
     Parent or Holdco Sub and their respective subsidiaries taken as a whole. 
     The Merger will be consummated without the vote of the stockholders of
     Parent, pursuant to the provisions of Section 251(g) of the DGCL.

          (g) SEC FILINGS.

               (i)  Parent has timely filed all reports, schedules, forms,

          December 31, 1995 (the "PARENT SEC DOCUMENTS").

               (ii) As of its filing date, each Parent SEC Document did not
          contain any untrue statement of a material fact or omit to state any
          material fact necessary in order to make the statements therein, in
          the light of the circumstances under which they were made, not
          misleading, except to the extent that such statements have been
          modified or superseded by a later filed Parent SEC Document.

          (h) FINANCIAL STATEMENTS.  The audited consolidated financial
     statements and unaudited consolidated interim financial statements of
     Parent included in Parent's Annual Report on Form 10-K for the fiscal year
     ended December 31, 1996 (the "PARENT 10-K") and its Quarterly Report on
     Form 10-Q for the fiscal quarter ended September 30, 1997 have been
     prepared in accordance with generally accepted accounting principles
     (except, in the case of unaudited statements, as permitted by Form 10-Q of
     the SEC) applied on a consistent basis during the periods involved (except
     as may be indicated in the notes thereto) and fairly present the
     consolidated financial position of Parent and its consolidated subsidiaries
     as of the dates thereof and their consolidated results of operations and
     cash flows for the periods then ended (subject to normal year-end
     adjustments in the case of any unaudited interim financial statements).

          (i) NO BUSINESS ACTIVITIES.  (i)  Holdco Sub has not conducted any
     activities other than in connection with the organization of Holdco Sub and
     Merger Sub, the negotiation and execution of this Agreement and the Merger
     Agreement and the consummation of the transactions contemplated hereby and
     thereby.  

          (ii)  As of the date of this Agreement Holdco Sub has, and as of
     immediately prior to the Closing Holdco Sub will have, no liabilities or
     obligations of any nature whatsoever, whether fixed, accrued, contingent,
     determined, determinable or otherwise and whether pursuant to contracts or
     otherwise (collectively, "LIABILITIES"), except those arising under or in
     connection with this Agreement, the Merger Agreement, the Standstill
     Agreement and the Registration Rights Agreement and the consummation of the
     transactions contemplated hereby and thereby.

          (j) NO REQUIRED VOTE.  No vote of the holders of any class of the
     outstanding capital stock of Parent is necessary to approve this Agreement,
     the Merger or the Transactions. 

          (k)  NO BROKER.  No investment banker, broker, finder, consultant or
     intermediary is entitled to be paid any investment banking, brokerage,
     finder's or similar fee or commission by Parent or Holdco Sub in connection

          3.2 REPRESENTATIONS AND WARRANTIES OF THE PARTNERSHIP AND THE
PARTNERS.  The Partnership and each Partner, severally and not jointly,
represents and warrants to Parent and Holdco Sub as of the date hereof and as of
the Closing Date as follows:

          (a) ORGANIZATION, STANDING AND POWER OF THE PARTNERSHIP.  The
     Partnership is duly organized, validly existing and in good standing under
     the laws of the State of Texas and has the requisite partnership power and
     authority to carry on its business as now being conducted.  The Partnership
     is duly qualified or licensed to do business and is in good standing in
     each jurisdiction in which the nature of its business or the ownership or
     leasing of its properties makes such qualification or licensing necessary,
     other than in such jurisdictions where the failure to be so qualified or
     licensed (individually or in the aggregate) could not reasonably be
     expected to have a material adverse effect with respect to the Partnership.
     The Partnership has delivered to Parent complete and correct copies of its
     certificate of limited partnership and the Partnership Agreement, in each
     case as amended to the date of this Agreement.

          (b) PARTNERSHIP AUTHORIZATION.  The execution, delivery and
     performance by the Partnership of this Agreement and the consummation by
     the Partnership of the transactions contemplated hereby have been duly
     authorized by all necessary partnership action, and by all necessary action
     on the part of each Partner.  This Agreement has been duly executed and
     delivered by the Partnership and constitutes a valid and binding agreement
     of the Partnership, enforceable against the Partnership in accordance with
     its terms (subject to applicable bankruptcy, insolvency, reorganization,
     moratorium, fraudulent transfer and other similar laws affecting creditors'
     rights generally from time to time in effect and to general principles of
     equity, including concepts of materiality, 

<PAGE>

                                                                             13

     reasonableness, good faith and fair dealing, regardless of whether in a
     proceeding at equity or at law).          

          (c) PARTNERSHIP CAPITALIZATION.  The authorized and issued equity
     capital of the Partnership consists solely of the general partnership
     interests and limited partnership interests described on Schedule 3.2(c). 
     The Partners own, and at the Closing Date the Partners will own, of record
     and beneficially, collectively 100% of the general and limited partnership
     interests of the Partnership, free and clear of all Liens and Restrictions
     (other than any Liens or Restrictions imposed pursuant to the terms of this
     Agreement or disclosed on Schedule 3.2(c)).  Immediately following the
     transactions contemplated by this Agreement, no Person (other than Holdco
     Sub and Parent) will own any interest in the Partnership.  There are no
     warrants, options, rights, convertible securities or other agreements,
     arrangements or commitments which obligate the Partnership to admit any
     Person to the Partnership or to issue or dispose of any equity interest in
     the Partnership except for this Agreement.

          (d) OWNERSHIP OF SHARES OF COMPANY COMMON STOCK; NO OTHER OPERATIONS. 
     The Partnership is the direct and record owner of (i) 5,263,188 shares of
     Company Class A Common Stock, (ii) no shares of Class B Common Stock, par
     value $.01 per share, of the Company ("COMPANY CLASS B COMMON STOCK" and,
     together with the Company Class A Common Stock, the "COMPANY COMMON
     STOCK"), (iii) the $7.50 Warrant, which may be exercised as to 2,298,134
     shares of Company Class A Common Stock at a price of $7.50 per share and
     the $15.00 Warrant, which may be exercised as to 741,334 shares of Company
     Class A Common Stock at a price of $15.00 per share and which Warrants
     expire on April 27, 1998 (it being understood that at Closing, instead of
     the Warrants, the Partnership shall own all the shares of Company Class A
     Common Stock issued upon exercise of the Warrants), and (iv) no warrants to
     purchase shares of Company Class B Common Stock.  Except as set forth in
     the immediately preceding sentence, (i) the Partnership does not own or
     have the right to acquire, whether presently exercisable or at any time in
     the future, any shares of Company Common Stock or any securities
     convertible into or exercisable or exchangeable for shares of Company
     Common Stock or any other equity securities of the Company and (ii) the
     Partnership does not own any other assets or conduct any other business. 
     No Person has the right to acquire, and neither the Partnership nor any of
     the Partners is a party to any contract, understanding, commitment,
     arrangement or other agreement to sell, transfer or otherwise dispose of,
     any shares of Company Common Stock owned by or issuable to the Partnership.
     To the best knowledge of the Partnership and the Partners, based solely on
     inquiry of appropriate officers of the Company, as of December 31, 1997,
     the shares of Company Class A Common Stock described in the first sentence
     of this Section 3.2(d), assuming exercise of the Warrants, constituted
     13.9% of the outstanding shares of Company Common Stock and 50.4% of the
     Voting Power represented by the outstanding shares of Company Common Stock.
     To the best knowledge of the Partnership and the Partners, based solely on
     inquiry of appropriate officers of the Company, after giving effect to the
     issuance of shares of Company Common Stock pursuant to all securities
     described in the second sentence of Section 3.3(h), such shares would have
     constituted 9.6% of the outstanding shares of Company Common Stock and
     43.9% of the Fully Diluted Voting Power at December 31, 1997.  The
     Partnership has, and at the Closing will have, good and valid title to the
     shares of Company Class A Common Stock described in the first sentence of 

<PAGE>

                                                                             14

     this Section 3.2(d) and the shares of Company Class A Common Stock issuable
     upon exercise of the Warrants, free and clear of any Liens or Restrictions,
     except those arising under this Agreement.  The Partnership has the sole
     voting power, and sole power of disposition, with respect to all of such
     shares of Company Class A Common Stock and the Warrants, and there are no
     restrictions on the Partnership's ability to transfer such shares or the
     Warrants.

          (e) ABSENCE OF UNDISCLOSED LIABILITIES.  At the Closing, the
     Partnership will have no Liabilities, except those arising out of the
     Transactions.

          (f) NO CONFLICT.  Other than (i) the filing of an amendment to its
     Report on Schedule 13D under the Exchange Act and (ii) compliance with any
     applicable requirements of the HSR Act, no filing with, and no permit,
     authorization, consent or approval of, any Governmental Authority is
     necessary for the execution of this Agreement by the Partnership or the
     consummation by the Partnership or any Partner of the transactions
     contemplated hereby, except for such filings the failure of which to be
     made, individually or in the aggregate, could not reasonably be expected to
     have a material adverse effect on the Partnership or any Partner or to
     prevent or materially delay the consummation of the transactions
     contemplated hereby.  Neither the execution and delivery of this Agreement
     by the Partnership nor the consummation by the Partnership of the
     transactions contemplated hereby nor compliance by the Partnership with any
     of the provisions hereof conflicts with or results in any breach of any
     applicable trust or other organizational documents applicable to the
     Partnership, including the Partnership Agreement.
 
          3.3 REPRESENTATIONS AND WARRANTIES OF THE PARTNERS AND THE
TRANSFERORS.  Each Partner (which term shall for purposes of this Section 3.3
include the Transferors) severally, and not jointly, represents and warrants to
Parent and Holdco Sub as to itself, in the case of Sections 3.3(a) through (f),
as of the date hereof and as of the Closing Date as follows:

          (a) ORGANIZATION, STANDING AND POWER OF EACH OF THE PARTNERS.  Such
     Partner has the legal capacity (in the case of individual Partners) or, as
     the case may be, the corporate or partnership power and authority to enter
     into and perform all of such Partner's obligations under this Agreement and
     the Standstill Agreement.  Neither the execution and delivery of this
     Agreement or the Standstill Agreement by such Partner nor the consummation
     by such Partner of the transactions contemplated hereby nor compliance by
     such Partner with the provisions hereof or of the Standstill Agreement
     conflicts with or results in any breach of any applicable trust or other
     organizational documents applicable to such Partner or of the Partnership
     Agreement or constitutes a dissolution event under the Partnership
     Agreement or otherwise.  There is no beneficiary or holder of voting trust
     certificates or other interest of any trust of which such Partner is
     trustee whose consent is required for the execution and delivery of this
     Agreement or the consummation of the transactions contemplated hereby.  If
     such Partner is married and such Partner's Partnership Interest or
     Allocable Company Class A Shares constitute community property, this
     Agreement has been duly authorized, executed and delivered by, and
     constitutes a valid and binding agreement of, such Partner's spouse,
     enforceable against such Person in accordance with its terms.

<PAGE>

                                                                             15

          (b) PARTNER AUTHORIZATION.  The execution, delivery and performance of
     this Agreement and the Standstill Agreement and the consummation by such
     Partner of the transactions contemplated hereby and thereby have been duly
     authorized by such Partner (and if necessary, by any stockholders or
     partners of such Partner).  This Agreement has been and the Standstill
     Agreement will be as of the Closing Date duly and validly executed and
     delivered by such Partner and constitutes or will constitute a valid and
     binding agreement of such Partner, enforceable against such Partner in
     accordance with its terms (subject to applicable bankruptcy, insolvency,
     reorganization, moratorium, fraudulent transfer and other similar laws
     affecting creditors' rights generally from time to time in effect and to
     general principles of equity, including concepts of materiality,
     reasonableness, good faith and fair dealing, regardless of whether in a
     proceeding at equity or at law).   

          (c) TITLE TO PARTNERSHIP INTERESTS.  Such Partner is the legal and
     valid owner and, in the case of the Transferors, the direct and record
     owner of, and, except as set forth on Schedule 3.2(c), has good and valid
     title, free and clear of any Liens or Restrictions to, its Partnership
     Interest or, in the case of the Transferors, the shares of Company Class A
     Common Stock owned by it and set forth on Schedule 2.2(b).  Such Partner's
     allocable interest in the total number of shares of Company Class A Common
     Stock and the Warrants owned by the Partnership is set forth on Schedule
     2.2(a) in the case of Cash Electing Partners (which term shall for purposes
     of this Section 3.3 include Transferor III) and Schedule 2.2(b) in the case
     of Share Electing Partners (which term shall for purposes of this Section
     3.3 include Transferor I and Transferor II).   

          (d) INVESTMENT INTENTION.  Such Partner, if it is a Share Electing
     Partner, is acquiring the Exchange Shares to be acquired by it for its own
     account as principal for investment and not with a view to resale or
     distribution or with any present intention of distributing or selling the
     same.  Such Share Electing Partner is fully aware that such Exchange Shares
     have not been registered under the Securities Act or under any applicable
     state securities laws, and are being offered and sold in reliance on
     exemptions from the registration requirements of the Securities Act and all
     such laws.  Such Share Electing Partner is an "accredited investor" as such
     term is defined in Regulation D promulgated under the Securities Act.  Such
     Share Electing Partner is able to bear the economic risk of the investment
     in such Exchange Shares and has such knowledge and experience in financial
     and business matters, and knowledge of the business of Parent (and after
     the Merger, Holdco Sub), as to be capable of evaluating the merits and
     risks of a prospective investment.  

          (e) LIMITATIONS ON TRANSFERABILITY.  Such Partner, if it is a Share
     Electing Partner, acknowledges that it may not transfer any of the Exchange
     Shares received by it pursuant hereto unless and until the same are
     registered under the Securities Act and any applicable state securities
     laws, or unless an exemption from such registration is available and that
     it may transfer such Exchange Shares only in accordance with the terms of
     this Agreement and the Standstill Agreement.

          (f) LEGEND.  In furtherance of the agreements contained in Sections
     3.3(d) and (e), each of the Share Electing Partners agrees that the
     certificate or certificates representing the Exchange Shares beneficially
     owned by it shall bear the following legend:

<PAGE>

                                                                             16

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF
     THE INVESTMENT AGREEMENT, DATED AS OF JANUARY 25, 1998, AMONG NORTHWEST
     AIRLINES CORPORATION, NEWBRIDGE PARENT CORPORATION, AIR PARTNERS, L.P., THE
     PARTNERS OF AIR PARTNERS, L.P. IDENTIFIED ON THE SIGNATURE PAGES THEREOF,
     BONDERMAN FAMILY LIMITED PARTNERSHIP, 1992 AIR, INC. AND AIR SAIPAN, INC.
     AND THE STANDSTILL AGREEMENT, DATED AS OF __________ __, 1998, BETWEEN
     NORTHWEST AIRLINES CORPORATION AND THE HOLDERS IDENTIFIED ON THE SIGNATURE
     PAGES THEREOF (COLLECTIVELY, THE "AGREEMENTS"), WHICH PROVIDE THAT (A) THE
     HOLDER IS PROHIBITED FROM TRANSFERRING THESE SHARES AS PROVIDED IN THE
     AGREEMENTS AND (B) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE
     SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, ASSIGNED, TRANSFERRED,
     PLEDGED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH, OR PURSUANT TO
     AN EXEMPTION FROM, THE REQUIREMENTS OF SUCH ACT OR SUCH LAWS.  

     Holdco Sub will exchange certificates without the foregoing legend upon the
     request of a Share Electing Partner at such time as the holder thereof may
     sell such shares without registration of such sale under the Securities
     Act, as evidenced (if requested by Holdco Sub) by an opinion of counsel to
     such holder.

          (g) NO BROKER.  No investment banker, broker, finder, consultant or
     intermediary is entitled to be paid any investment banking, brokerage,
     finder's or similar fee or commission by the Partnership, any Partner or
     any Transferor in connection with this Agreement or the Transactions for
     which any of the Partnership, Parent or Holdco Sub would be liable
     following the Closing.

          (h) COMPANY CAPITALIZATION.   To the best knowledge of the Partners,
     based solely on inquiry of appropriate officers of the Company, the
     authorized capital stock of the Company consists of (i) 10,000,000 shares
     of Preferred Stock, par value $.01 per share ("COMPANY PREFERRED STOCK"),
     and (ii) (x) 50,000,000 shares of Company Class A Common Stock, (y)
     200,000,000 shares of Company Class B Common Stock and (z) 50,000,000
     shares of Class D Common Stock, par value $.01 per share (the "COMPANY
     CLASS D COMMON STOCK").  To the best knowledge of the Partners, based
     solely on inquiry of appropriate officers of the Company, as of the close
     of business on December 31, 1997, there were (i) no shares of Company
     Preferred Stock, 8,379,464 shares of Company Class A Common Stock,
     50,512,010 shares of Company Class B Common Stock and no shares of Company
     Class D Common Stock issued and outstanding; (ii) no shares of capital
     stock held in the treasury of the Company; (iii) 5,991,472 shares of
     Company Class B Common Stock reserved for issuance upon exercise of
     authorized but unissued stock options of the Company pursuant to the
     Company's employee stock option and similar plans; (iv) 7,617,155 shares of
     Company Class B Common Stock reserved for issuance upon the conversion of
     the Company's outstanding 6-3/4% Convertible Subordinated Notes due 2006;
     (v) 10,311,208 shares of Company Class B Common Stock reserved for issuance
     upon the conversion of the Company's outstanding 8-1/2%

                                                                             17

     Convertible Subordinated Deferrable Interest Debentures due 2020; (vi)
     3,039,468 shares of Company Class A Common Stock issuable upon exercise of
     the Warrants; and (vii) 308,343 shares of Company Class B Common Stock
     issuable upon exercise of the Warrants.  To the best knowledge of the
     Partners, based solely on inquiry of appropriate officers of the Company,
     except as described in the immediately preceding sentence, there are no
     securities of the Company (or any of its affiliates) currently outstanding
     that are convertible into or exercisable or exchangeable for shares of
     Company Common Stock other than (a) options to purchase shares of Company
     Class B Common Stock granted in accordance with past practices pursuant to
     stock option and similar plans, (b) options to purchase shares of Company
     Class B Common Stock granted pursuant to the Company's 1997 Employee Stock
     Purchase Plan, (c) shares of Company Class A Common Stock, which are
     convertible into shares of Company Class B Common Stock or Company Class D
     Common Stock on a one-for-one basis and (d) commitments to issue not in
     excess of 25,000 shares of Company Class B Common Stock to correct
     recordkeeping errors in connection with the Company's 1994 Employee Stock
     Purchase Plan.  To the best knowledge of the Partners, based solely on
     inquiry of appropriate officers of the Company, on the Closing Date, all
     outstanding shares of the Company's capital stock will be duly authorized,
     validly issued, fully paid and non-assessable.

          3.4 REPRESENTATIONS AND WARRANTIES OF THE TRANSFERORS.  Transferor I,
Transferor II and Transferor III are the direct and record owners of 16,400,
213,110 and 3,702 shares, respectively, of Company Class A Common Stock.  Except
as set forth in the immediately preceding sentence and except in accordance with
their rights as Partners in the Partnership, no Transferor owns or has the right
to acquire, whether presently exercisable or at any time in the future, any
shares of Company Class A Common Stock or any securities convertible into or
exercisable or exchangeable for shares of Company Class A Common Stock.  No
person has the right to acquire, and no Transferor is a party to any contract,
understanding, commitment, arrangement or other agreement to sell, transfer or
otherwise dispose of, any shares of Company Class A Common Stock owned by or
issuable to such Transferor.  To the best knowledge of the Transferors, based
solely on inquiry of appropriate officers of the Company, the shares of Company
Class A Common Stock described in the first sentence of this Section 3.4
constituted 0.4% of the outstanding shares of Company Common Stock and 1.74%% of
the Voting Power represented by the outstanding shares of Company Common Stock
as of December 31, 1997.  To the best knowledge of the Transferors, based solely
on inquiry of appropriate officers of the Company, after giving effect to the
issuance of shares of Company Common Stock pursuant to all securities described
in the second sentence of Section 3.3(h), such shares would have constituted
0.27% of the outstanding shares of Company Common Stock and 1.23% of the Fully
Diluted Voting Power as of December 31, 1997.  The Transferors have, and at the
Closing will have, good and valid title to the shares of Company Class A Common
Stock described in the first sentence of this Section 3.4, free and clear of any
Liens or Restrictions, except those arising under this Agreement.  Each
Transferor has the sole voting power, and sole power of disposition, with
respect to all of such shares of Company Class A Common Stock and there are no
restrictions on such Transferor's ability to transfer such shares.

                                      COVENANTS

          4.1 COVENANTS OF PARENT AND HOLDCO SUB. (a)  NASDAQ NATIONAL MARKET. 
Parent and Holdco Sub shall use their reasonable best efforts to cause the
shares of Holdco Sub Class A Common Stock to be issued to the Share Electing
Partners and the Transferors pursuant to Section 2.2(b) to be approved for
quotation on the NASDAQ National Market, subject to official notice of issuance.

          (b) HOLDCO SUB BOARD OF DIRECTORS.  (i)  As promptly as practicable
following the Closing, the Board of Directors of Holdco Sub shall take such
corporate actions as are necessary to cause an individual designated by
Transferor II and reasonably acceptable to the Board of Directors of Holdco Sub
to be elected or appointed to the Board of Directors of Holdco Sub, to serve
until the next annual meeting of the Holdco Sub stockholders; PROVIDED, HOWEVER,
that it is hereby acknowledged that David Bonderman and William S. Price have
been deemed to be acceptable by the Board of Directors of Holdco Sub for
purposes of this Section 4.1(b)(i) and Section 4.1(b)(ii).

          (ii)  Commencing with the first annual or special meeting of
stockholders of Holdco Sub called for the election of directors to the Board of
Directors of Holdco Sub held following the Closing and at each annual or special
meeting of stockholders of Holdco Sub thereafter called for the election of
directors to the Board of Directors of Holdco Sub so long as, at the time of
such meeting, (A) the Share Electing Partners and the Share Electing Transferors
beneficially own in the aggregate at least 66-2/3% of the Exchange Shares issued
to them at the Closing or (B) the Offeree under Section 4.1(d) shall not have
acquired more than 50% of the shares of Company Common Stock beneficially
acquired by Parent and Holdco Sub in the Transactions (unless in the event of
such acquisition an Operating Alliance or Alliance Agreement shall be in effect
and no notice shall have been given by either party to an Alliance Agreement of
its intention to terminate such Alliance Agreement or the related Operating
Alliance), Transferor II shall be entitled to designate one person who shall be
reasonably acceptable to the Holdco Sub Board of Directors (the "TRANSFEROR II
DESIGNEE") for election to the Board of Directors of Holdco Sub and Holdco Sub
shall nominate and recommend the Transferor II Designee for election to the
Board of Directors of Holdco Sub and shall use its best efforts to ensure that
the Transferor II Designee is elected to such Board.  In the event that any
Transferor II Designee shall cease to serve as a director for any reason, the
vacancy resulting thereby shall be filled by a Person designated by Transferor
II and reasonably acceptable to the Board of Directors of Holdco Sub.

          (iii)  If at any time (A) the Share Electing Partners and the Share
Electing Transferors beneficially own in the aggregate less than 66-2/3% of the
Exchange Shares issued to them at the Closing or (B) the Offeree under Section
4.1(d) acquires more than 50% of the shares of Company Common Stock beneficially
acquired by Parent and Holdco Sub in the Transactions, and there shall not be in
effect an Operating Alliance or an Alliance Agreement or notice shall have been
given by either party to an Alliance Agreement of its intention to terminate
such Alliance Agreement or the related Operating Alliance, (1) Transferor II
shall as promptly as practicable cause the Transferor II Designee to resign from
the Board of Directors of Holdco Sub and (2) the right set forth in Section
4.1(b)(ii) shall not be reinstated notwithstanding any 

<PAGE>

                                                                             19

increase in the number of shares of Holdco Sub Class A Common Stock held by the
Share Electing Partners or the Share Electing Transferors that would cause such
percentage ownership to equal or exceed 66-2/3%.

          (iv)  Transferor II hereby agrees that all Transferor II Designees
shall be "Citizens of the United States" as such term is defined in the Federal
Aviation Act of 1958, as amended.  

          (c) CORPORATE STRUCTURE.  Parent and Holdco Sub agree that, for a
period of at least two years following the Closing Date, they shall not take any
action which would cause or permit the liquidation of Holdco Sub or the merger
of Holdco Sub with or into Parent.

          (d)  RIGHTS OF OFFER AND RE-OFFER. (i)  In the event that prior to the
fifth anniversary of the Closing, if Holdco Sub, Parent or the Partnership (each
a "TRANSFERRING STOCKHOLDER") at any time intends to sell, transfer or otherwise
dispose of ("TRANSFER") any shares of Company Class A Common Stock held by
Parent, Holdco Sub or the Partnership as of the Closing Date to a third person,
Holdco Sub shall ensure that the Transferring Stockholder shall give written
notice (a "TRANSFEROR'S NOTICE") to Transferor II (the "OFFEREE") stating the
Transferring Stockholder's intention to make such Transfer and the number of
shares of Company Class A Common Stock proposed to be transferred (the "OFFERED
SECURITIES").

          (ii) Upon receipt of the Transferor's Notice, the Offeree may elect
to, and if the Offeree so elects the Transferring Stockholder shall, negotiate
in good faith, for a period of up to 30 days (such 30 day period, the "OFFER
PERIOD") from the date of the receipt by the Offeree of the Transferor's Notice,
the terms of a transaction in which the Offeree will acquire all of the Offered
Securities.  The Transferring Stockholder shall be under no obligation to accept
any offer made by the Offeree.  An offer made by the Offeree or the Transferring
Stockholder shall not be considered to be an offer for purposes of the remainder
of this Section 4.1(d) unless it is a bona fide offer made in good faith and
subject only to such conditions as are customary for offers of such type and, in
the good faith judgment of Parent or Holdco Sub, reasonably capable of being
satisfied within 60 days of the date of such offer.  

          (iii) If the Offeree does not reach a definitive agreement with the
Transferring Stockholder to purchase all of the Offered Securities or if the
Offeree offers to purchase less than all of the Offered Securities, the
Transferring Stockholder shall have the right, for a period of 75 days from the
earlier of (A) the expiration of the Offer Period and (B) the date on which such
Transferring Stockholder shall have received written notice from the Offeree
stating that the Offeree does not intend to exercise its right to offer to
purchase all of the Offered Securities, to enter into an agreement to Transfer
all or any portion of the Offered Securities to any third person at a price
equal to or greater than the price offered by the Offeree in its last offer (the
"LAST OFFER"), if any, for the Offered Securities (the "LAST OFFER PRICE");
PROVIDED, HOWEVER, that in the event the Transferring Stockholder notifies the
Offeree that it intends to publicly offer the Offered Securities or sell the
Offered Securities in the open market, unless the Offeree agrees to pay the
Transferring Stockholder a price per share for all the Offered Securities at
least equal to 100% of the closing price on the New York Stock Exchange
Composite Transactions Tape on the trading day immediately preceding the date of
the Transferor's Notice), the Transferring Stockholder shall, for a period of
six months following such notification, be free to sell the Offered Securities
in such an offering or open market transaction at a price no less than 95% of
the market price at the time of any such sale without regard to this Section
4.1(d) other than this 

<PAGE>

                                                                             20

Section 4.1(d)(iii).  If any portion of the Last Offer Price is proposed to be
paid in a form other than cash, the third person may pay such consideration in
the form proposed or in an amount of cash equal to the fair market value of such
non-cash consideration, as determined by an independent appraiser jointly
selected by the Transferring Stockholder and the Offeree (the "INDEPENDENT
APPRAISER").

          (iv) If (A) the proposed purchase price of a third party transferee
for the Offered Securities is less than the Last Offer Price or (B) such third
person offers to buy fewer Offered Securities than the Offeree had been offered
(but not if such latter offer is at a higher price than the Last Offer Price),
the Transferring Stockholder shall not Transfer any of the Offered Securities
unless the Transferring Stockholder shall first reoffer the Offered Securities
at such lesser price or such lesser amount to the Offeree (the "REOFFER") by
giving written notice (the "REOFFER NOTICE") to the Offeree of the Transferring
Stockholder's intention to make such Transfer at such lower price or in such
lesser amount (the "REOFFER PRICE") and the material terms and conditions of
such proposed Transfer.  The Offeree shall then have an irrevocable option
(provided notice of intent to exercise such option is given within ten days of
receipt of the Reoffer Notice by the Offeree (the "OPTION PERIOD")), subject to
Section 4.1(d)(vi), to purchase all or such number of the Offered Securities as
is set forth in the Reoffer Notice at the Reoffer Price and on the other terms
and conditions set forth therein; PROVIDED, HOWEVER, that if any portion of the
Reoffer Price is to be paid in a form other than cash, the Offeree shall have
the option to pay such consideration in an amount of cash equal to the fair
market value of such non-cash consideration as determined by an Independent
Appraiser, so long as such payment would not cause the Transferring Stockholder
to incur incremental tax liability from the terms set forth in the Reoffer
Notice, and otherwise in a form of non-cash consideration determined by an
Independent Appraiser to provide reasonably equivalent economic value (taking
into account tax and credit considerations, as well as such other considerations
as the Independent Appraiser considers appropriate).  If the Offeree does not
elect to purchase all of the Offered Securities at the Reoffer Price or elects
(if permissible because the Transferring Stockholder shall have consented to the
purchase by a third party of less than all of the Offered Securities) to
purchase less than all of the Offered Securities, the Transferring Stockholder
shall have the right to enter into an agreement to Transfer the Offered
Securities to such third person or any other third person, on terms at least as
favorable to the Transferring Stockholder as those specified in the Reoffer
Notice, for a period of 75 days following the earlier of (A) the expiration of
the Option Period with respect to the Reoffer or (B) the date on which the
Transferring Stockholder shall have received written notice from the Offeree
stating that it does not intend to exercise its option to purchase all of the
Offered Securities specified on the terms in the Reoffer Notice. 

          (v) If the Offeree exercises its right of Reoffer, the closing of the
purchase of the Offered Securities with respect to which such right has been
exercised shall take place on the 15th day after the later of (A) the date the
Offeree gives notice of such exercise and (B) the expiration of such time as the
parties may reasonably require in order to comply with applicable United States
federal and state laws and regulations, which in no event shall be more than 60
days after the date specified in clause (A) (or such longer period as may be
necessary to obtain all required governmental consents or approvals identified
in Section 5.1); PROVIDED, HOWEVER, that in the event that the Transferor's
Notice is received by the Offeree prior to the date that is six months following
the Closing (the "INITIAL PERIOD"), no such purchase (nor any negotiated
purchase pursuant to Section 4.1(d)(i)) shall be required to close prior to the
date which is three days following the last day of the Initial Period.  Upon
exercise by the Offeree of its right of 

<PAGE>

                                                                             21

Reoffer under this Section 4.1(d), the Offeree and the Transferring Stockholders
shall be legally obligated to consummate the purchase contemplated thereby and
shall use their best efforts to make all necessary filings and to secure any
approvals required and to comply as soon as practicable with all applicable
United States federal and state laws and regulations in connection therewith.

          (vi) The Transferring Stockholder may determine at any time prior to
the earlier of the execution of a definitive agreement and the termination of
the Option Period not to Transfer the Offered Securities, in which case all of
the provisions of this Section 4.1(d) shall again become applicable to any
Transfers of shares of Company Class A Common Stock by the Transferring
Stockholders.

          (vii) The parties agree that all communications from Parent, Holdco
Sub or the Partnership in connection with the matters set forth in this Section
4.1(d) constitute material and confidential inside information and shall not be
disclosed by the Offeree to its affiliates or to any other person without the
prior written consent of Holdco Sub, except as may be required by law in the
written opinion of counsel of the Offeree.

          (viii) If the Offeree and the Transferring Stockholder do not reach an
agreement to Transfer the Offered Securities to the Offeree in accordance with
the provisions of this Section 4.1(d) and the Transferring Stockholder shall not
have entered into an agreement to Transfer the Offered Securities to a third
Person in accordance with the provisions of this Section 4.1(d), the right of
first offer under this Section 4.1(d) shall again apply in connection with any
subsequent Transfer of such Offered Securities.

          (e) PURCHASES OF COMPANY COMMON STOCK PRIOR TO THE CLOSING.  Parent
agrees to use its best efforts to purchase or otherwise acquire, concurrently
with or prior to the Closing, such number of shares of Company Common Stock (the
"ACQUIRED SHARES"), whether through open market purchases, in negotiated
transactions or otherwise, as is necessary so that the Voting Power of the
Acquired Shares, together with the Voting Power of the shares of Company Common
Stock beneficially owned by the Partnership and the Transferors, shall at the
Closing constitute at least 50.1% of the Fully Diluted Voting Power of all
holders of Company Common Stock.

          4.2 COVENANTS OF THE PARTNERSHIP, THE PARTNERS AND THE TRANSFERORS.

          (a) NO SOLICITATION.

          (i)  From the date of this Agreement until the earlier of (i) the
     termination of this Agreement and (ii) the first anniversary of the
     Closing, none of the Partnership (so long as the Partnership is owned and
     controlled by the Partners and/or the Transferors) or any of the Partners
     (which term shall for purposes of this Section 4.2(a) include the
     Transferors) shall, directly or indirectly, through any partner, officer,
     director, employee, representative or agent of the Partnership or any of
     the Partners or any of their affiliates or otherwise, solicit, initiate or
     encourage any inquiries, offers or proposals, or any indications of
     interest, regarding (A) any merger, reorganization, share exchange,
     consolidation, business combination, recapitalization, liquidation,
     dissolution or similar transaction involving the Company (together with the
     transactions described in clauses 


<PAGE>

                                                                             22

     (B)(1), (D) and (E) of this Section 4.2(a)(i), a "BUSINESS COMBINATION") or
     the Partnership, (B) any purchase or sale of all or any significant portion
     of the assets of (1) the Company or (2) the Partnership (it being
     understood that in the case of the Partnership any sale of any Company
     Class A Common Stock or any portion of the Warrants or the shares of
     Company Class A Common Stock issuable upon exercise thereof shall be deemed
     a significant portion), (C) any issuance or other sale or transfer of
     equity interests in the Partnership, (D) any issuance or other sale by the
     Company of any shares of Company Class A Common Stock or (E) any issuance
     or other sale by the Company of 5% or more (in any transaction or series of
     transactions) of any other class of equity securities of the Company or any
     of its subsidiaries (any of the foregoing inquiries, offers or proposals
     enumerated in clauses (A) through (E) being referred to herein as an
     "ACQUISITION PROPOSAL"), or participate in negotiations or discussions
     with, or provide any nonpublic information to, any Person (including the
     Company) relating to any Acquisition Proposal.  Without limiting the
     foregoing, neither the Partnership nor the Partners shall take any action
     that, in any such case, is intended to or could reasonably be expected to
     (w) prevent, (x) delay or postpone, (y) impede, frustrate or interfere with
     (in the case of this clause (y) in a manner that could reasonably be
     expected to substantially deprive Parent and Holdco Sub of the benefits of)
     the Transactions or the entry by the Company and Northwest Airlines, Inc.
     into a strategic worldwide operating alliance between them (an "OPERATING
     ALLIANCE") or the execution by the Company and Parent of any agreement
     contemplating the establishment of an Operating Alliance (an "ALLIANCE
     AGREEMENT") or (z) cause the Fully Diluted Voting Power represented by the
     shares of Company Class A Common Stock held by the Partnership and the
     Transferors to be less than that percentage of the Fully Diluted Voting
     Power of the Company represented by such shares on the date of this
     Agreement.

          (ii)      The Partnership and the Partners shall notify Parent and
     Holdco Sub as promptly as practicable if any Acquisition Proposal is made
     and shall in such notice indicate in reasonable detail the identity of the
     Person making such Acquisition Proposal and the terms and conditions of
     such Acquisition Proposal.

          (iii)     The Partnership and each of the Partners shall immediately
     cease any existing discussions or negotiations with any Persons (other than
     Parent and Holdco Sub) with which the Partnership or any Partner may have
     conducted discussions or negotiations heretofore with respect to any
     Acquisition Proposal.  The Partnership and each of the Partners agree not
     to release (by waiver or otherwise) any third party from the provisions of
     any confidentiality or standstill agreement to which the Partnership or any
     Partner is a party.  The Partners represent and warrant to Parent that, as
     of the time of execution, of this Agreement neither the Partnership nor any
     Partner is involved in any discussions or negotiations with any Person
     (other than Parent and Holdco Sub) relating to or that could reasonably be
     expected to lead to any Acquisition Proposal.

          (iv)      The Partnership and each of the Partners shall ensure that
     the partners, officers, directors and employees of the Partnership and each
     Partner and their respective subsidiaries and any investment banker or
     other advisor or representative retained by the Partnership or any Partner
     are aware of the restrictions described in this Section 4.2(a).

          (b) RESTRICTION ON TRANSFER OF COMPANY SHARES, PROXIES AND NON-
INTERFERENCE; RESTRICTION ON WITHDRAWAL.  Neither the Partnership nor any
Partner or Transferor shall, directly or indirectly, without the prior written
consent of Parent:  (i) except pursuant to or as expressly contemplated hereby,
offer for sale, sell (including short sales), transfer, tender, pledge,
encumber, assign or otherwise dispose of (including by gift), or enter into any
contract, option or other arrangement or understanding (including any
profit-sharing arrangement) with respect to or consent to the offer for sale,
sale, transfer, tender, pledge, encumbrance, assignment or other disposition of,
(A) any or all of the shares of Company Class A Common Stock owned by it (or, in
the case of any Partner, allocable to it) or the Warrants (or, in the case of
any Partner, its allocable interest therein and in the shares of Company Class A
Common Stock issuable upon the exercise thereof) or (B) in the case of any
Partner, all or any portion of its Partnership Interest, or any interest in any
thereof; (ii) except as expressly contemplated hereby, grant any proxies or
powers of attorney (other than to a Partner or Transferor), deposit any shares
of Company Class A Common Stock into a voting trust or enter into any other
voting arrangement with respect to any shares of Company Class A Common Stock;
(iii) take any action that would make any representation or warranty of the
Partnership or any Partner or Transferor contained herein untrue or incorrect or
have the effect of preventing or disabling the Partnership or any Partner or
Transferor from performing its obligations under this Agreement; or (iv) in the
case of the Partners, withdraw any of its Allocable Company Class A Shares (or
its allocable portion of the Warrants) from the Partnership or elect to have any
of its Allocable Company Class A Shares distributed to it; or commit or agree to
take any of the foregoing actions; PROVIDED, HOWEVER, that in the event that (i)
a third party commences a bona fide tender offer for shares of Company Class A
Common Stock, (ii) neither the Partnership nor any Partner or Transferor is in
breach in any material respect of its representations and warranties or its
obligations (including its obligation to effect the Closing) under this
Agreement and (iii) all of the other conditions to Parent's and Holdco Sub's
obligations to close the Transactions set forth in Sections 5.1 and 5.2 have
been satisfied, unless Parent and Holdco Sub cause the Closing to occur within
five Business Days following receipt of written notice from the Partnership or
any of the Transferors of their intention to tender their shares, the
Partnership and the Transferors will be permitted to tender their shares of
Company Class A Common Stock in such tender offer, unless such Closing shall not
have occurred as a result of facts or occurrences not within the control of
Parent and Holdco Sub (including the failure of any of the conditions set forth
in Section 5.1 or Section 5.3 to be satisfied).

          (c) VOTING.  The Partnership, each Transferor and each Partner (with
respect to its right to direct the vote of the shares of Company Class A Common
Stock owned by the Partnership in accordance with the terms of the Partnership
Agreement) hereby agree that, during the time this Agreement is in effect, at
any meeting of the stockholders of the Company (or at any adjournments or
postponements thereof), however called, or in any other circumstances upon which
the Partnership's or such Transferor's vote, consent or other approval is sought
or otherwise eligible to be given, the Partnership, each Transferor and such
Partners shall vote (or cause to be voted) the shares of Company Class A Common
Stock owned by the Partnership or such Transferor, as the case may be, (i)
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation or
agreement of the Partnership or the Partners or such Transferor under this
Agreement; and (ii) except as otherwise agreed to in writing in advance by
Parent, against the following actions:  (A) any Business Combination (other than

                                                                             24

change in the present capitalization of the Company or any amendment of the
Company's Certificate of Incorporation or By-laws; (3) any other material change
in the Company's corporate structure or business; (4) any other action which is
intended, or could reasonably be expected, to (x) prevent, (y) delay or postpone
or (z) impede, frustrate or interfere with (in the case of this clause (z), in a
manner that could reasonably be expected to substantially deprive Parent and
Holdco Sub of the material benefits of any of) the Transactions or the entry by
the Company and Northwest Airlines, Inc. into an Operating Alliance or their
execution of an Alliance Agreement, or (5) any action that would cause the Fully
Diluted Voting Power represented by the shares of Company Class A Common Stock
held by the Partnership and the Transferors to be less than that percentage of
the Fully Diluted Voting Power of the Company represented by such shares on the
date of this Agreement other than grants by the Company to its employees in
accordance with its past practices of options and other stock-based
compensation.  Neither the Partnership nor any Partner or Transferor shall enter
into any agreement or understanding with any Person or entity prior to the
termination of this Agreement to vote or give instructions after such
termination in a manner inconsistent with clauses (i) or (ii) of the preceding
sentence.

          (d)  PROXY.  The Partnership (and, to the extent provided by the
Partnership Agreement, the Partners) and each Transferor hereby grant to, and
appoint, Robert L. Friedman and any other designee of Parent, individually, its
irrevocable proxy and attorney-in-fact (with full power of substitution) to vote
the shares of Company Class A Common Stock owned by the Partnership or such
Transferor as indicated in, and solely for the purposes of, Section 4.2(c).  The
Partnership (and the Partners) and each Transferor intend this proxy to be
irrevocable and coupled with an interest and will take such further action and
execute such other instruments as may be necessary to effectuate the intent of
this proxy and hereby revoke any proxy previously granted by it with respect to
the matters set forth in Section 4.2(c) with respect to the shares of Company
Class A Common Stock owned by the Partnership.  Notwithstanding the foregoing,
Parent agrees that the proxy granted by this Section 4.2(d) shall be deemed to
be revoked upon the termination of this Agreement in accordance with its terms. 
     

          (e) TAX REPRESENTATIONS LETTER.  Each of the Share Electing Partners
and the Transferors agrees that it will provide to Simpson Thacher & Bartlett
and to Kelly, Hart & Hallman such representations and warranties as may be
required for the delivery of the tax opinions referred to in Sections 5.2(e) and
5.3(c).

          (f) NO CONVERSIONS.  The Partnership and each Transferor agree not to
convert any shares of Company Class A Common Stock into shares of Company Class
B Common Stock.

          (g)BINDING OBLIGATIONS.  Notwithstanding, and without in any way
limiting, any other provision of this Agreement, the Partnership, each of the
Partners and each Transferor acknowledges that, subject to the satisfaction (or
waiver by them) of the conditions set forth in Sections 5.1 and 5.3, their
obligations to consummate the Transactions, including the exchange of the
Partnership Interests and the transfer of beneficial ownership of the Company
Class A Common Stock owned by the Partnership, and the exchange of the shares of
Company Class A Common Stock owned by the Transferors, are absolute and
unconditional and shall not terminate except in accordance with Section 7.1,
irrespective of, without limitation, any receipt by the Company of an
Acquisition Proposal or any resolution by the Board of Directors of the Company 

<PAGE>

                                                                             25

to approve a Business Combination or otherwise.

          (h)  TRANSFER OF SHARES OF HOLDCO SUB CLASS A COMMON STOCK.  Each of
the Share Electing Partners and the Transferors agrees that it shall not,
directly or indirectly, offer, sell, transfer, tender, pledge or encumber,
assign or otherwise dispose of any Exchange Shares until the date that is two
years from the Closing Date, other than in connection with bona fide pledges of
such Exchange Shares to secure bona fide borrowings or in connection with bona
fide hedging transactions executed by registered broker-dealers; PROVIDED,
HOWEVER, that the Share Electing Partners and the Transferors shall be permitted
to offer, sell, transfer, tender, pledge or encumber, assign or otherwise
dispose of, during such two-year period (i) in the aggregate, such percentage of
the aggregate number of Exchange Shares issued to the Share Electing Partners
and the Transferors at the Closing as is equal to the percentage of the
aggregate shares of Holdco Sub Class A Common Stock beneficially owned by Alfred
Checchi, Gary Wilson and Richard Blum on the Closing Date that are sold,
transferred, assigned or otherwise actually disposed of by Alfred Checchi, Gary
Wilson and Richard Blum in the aggregate during such two-year period; (ii) in
the event that the Offeree acquires Offered Securities under Section 4.1(d), in
the aggregate, such percentage of the aggregate number of Exchange Shares issued
to the Share Electing Partners and the Transferors at the Closing as is
represented by the percentage such Offered Securities acquired by the Offeree
bears to the total number of shares of Company Class A Common Stock the
beneficial ownership of which is acquired by Parent and Holdco Sub at the
Closing and (iii) Exchange Shares to one or more of its affiliates that is
directly or indirectly controlled by it.
 
          (i) NO AMENDMENTS.  The Partnership and the Partners shall not agree
to amend, supplement or otherwise modify or terminate in any manner or waive any
provision of the Partnership Agreement, the Warrants, the Subscription and
Stockholders' Agreement, dated as of April 27, 1993, among the Partnership, Air
Canada and the Company, as amended through the date of this Agreement, or the
Amended and Restated Registration Rights Agreement, dated as of April 19, 1996,
among the Partnership, Air Canada and the Company or enter into any other
agreement with the Company relating to the Warrants or the shares of Company
Class A Common Stock beneficially owned by the Partnership, without the prior
written consent of Parent.

          (j)  RELEASE OF PARTNERSHIP FROM CERTAIN OBLIGATIONS.  In the event
that the Company receives a bona fide proposal (i) to undertake a transaction
described in clause (A) of the definition of Business Combination set forth in
Section 4.2(a)(i) (including a tender offer to acquire shares of Company Common
Stock that would represent at least 20% of the Voting Power of all holders of
Company Common Stock), (ii) to acquire all or substantially all of the Company's
assets or (iii) to acquire from the Company newly issued shares of Company
Common Stock that would represent at least 20% of the Voting Power of all
holders of Company Common Stock before giving effect to such issuance, Parent
shall have the right for a period of ten Business Days after such proposal is
publicly announced to deliver a notice (the "RELEASE NOTICE") to the Partners'
Representative and the Transferors stating its intention to release the
Partnership, each Transferor and each Partner from its obligations under
Sections 4.2(b) and (c); PROVIDED, HOWEVER, that Parent shall not be permitted
to exercise such right unless an independent committee of the Board of Directors
of the Company shall determine, taking into account the opinion of a nationally
recognized investment banking firm, that such proposal is superior, from a
financial point of view, to the stockholders of the Company, to the transactions

<PAGE>

                                                                             26

contemplated hereby, it being understood that if such committee fails to make
such a determination, Parent shall have the opportunity to engage a nationally
recognized investment banking firm mutually selected by Parent and the Holders'
Representative, and if such firm makes such a determination, Parent shall be
permitted to exercise such right.  The Release Notice shall become effective
upon the delivery thereof to the Partners' Representative and the Transferors in
accordance with the terms of this Agreement.

          4.3 REASONABLE BEST EFFORTS.  (a)  Subject to the terms and conditions
of this Agreement, each party will use its reasonable best efforts to take, or
cause to be taken, all actions to do, or cause to be done, all things necessary,
proper or advisable under applicable laws and regulations to consummate the
transactions contemplated by this Agreement.  In furtherance and not in
limitation of the foregoing, each of Parent and the Partnership agrees, and the
Partnership and each of the Partners and the Transferors agrees to use its
reasonable best efforts to cause the Company, to file a Notification and Report
Form pursuant to the HSR Act and any other required regulatory filings with
foreign antitrust authorities, the DOT and any other entity as promptly as
practicable following the execution of this Agreement and in any event no more
than ten Business Days thereafter and to supply as promptly as practicable any
additional information and documentary material that may be requested pursuant
to the HSR Act or by any Governmental Authority and to take all other actions
necessary to cause the expiration or termination of the applicable waiting
periods under the HSR Act as soon as practicable.  Such filings shall seek
approval for the transactions contemplated by this Agreement on the basis as if
Parent was acquiring more than 50% of the outstanding capital stock of the
Company (the "COMPANY ACQUISITION CASE").

          (b)  Each of the parties hereto shall, in connection with the efforts
referenced in Section 4.3(a) to obtain all requisite approvals and
authorizations for the transactions contemplated hereby, including the Company
Acquisition Case, under the HSR Act or any other Antitrust Law (as defined
below), use its reasonable best efforts to (i) cooperate in all respects with
each other in connection with any filing or submission and in connection with
any investigation or other inquiry, including any proceeding initiated by a
private party; (ii) keep the other parties informed in all material respects of
any material communication received by such party from, or given by such parties
to, the Federal Trade Commission (the "FTC"), the Antitrust Division of the
Department of Justice (the "DOJ"), the DOT, the European Commission or any other
Governmental Authority and of any material communication received or given in
connection with any proceeding by a private party, in each case regarding the
transactions contemplated hereby, including the Company Acquisition Case; and
(iii) permit the other parties to review any material communication given by it
to, and consult with each other in advance of any meeting or conference with,
the FTC, the DOJ, the DOT, the European Commission or any such other
Governmental Authority or, in connection with any proceeding by a private party,
with any other Person, and to the extent permitted by the FTC, the DOJ, the DOT,
the European Commission or such other applicable Governmental Authority or other
Person, give the other parties the opportunity to attend and participate in such
meetings and conferences.  For purposes of this Agreement, "ANTITRUST LAW" means
the Sherman Act, as amended, the Clayton Act, as amended, the HSR Act, the
Federal Trade Commission Act, as amended, applicable DOT regulations, and all
other federal, state and foreign statutes, rules, regulations, orders, decrees,
administrative and judicial doctrines and other laws that are designed or
intended to prohibit, restrict or regulate actions having the purpose or effect
of monopolization or restraint of trade or lessening of competition through
merger or acquisition.

          (c)  In furtherance and not in limitation of the covenants of the
parties contained in Sections 4.3(a) and (b), each of the parties hereto shall
use its reasonable best efforts to resolve such objections, if any, as may be
asserted with respect to the Transactions, including the Company Acquisition
Case, under any Antitrust Law, including taking all reasonable actions to obtain
clearance, or if such clearance cannot be obtained, to reach an agreement,
settlement, consent providing for divestiture, a "hold separate" agreement or
any other relief with the Governmental Authorities investigating the
Transactions; PROVIDED, HOWEVER, that the foregoing shall not require Parent to
agree to any asset divestiture or restriction on its or its subsidiaries' or the
Company's or its subsidiaries' business operations that would have a material
adverse effect on Parent or the Company.  In connection with the foregoing, if
any administrative or judicial action or proceeding, including any proceeding by
a private party, is instituted (or threatened to be instituted) challenging any
of the Transactions, including the Company Acquisition Case, as violative of any
Antitrust Law, each of the parties hereto shall cooperate in all respects with
each other and use its respective reasonable best efforts to contest and resist
any such action or proceeding and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order, whether temporary,
preliminary or permanent, that is in effect and that prohibits, prevents or
restricts consummation of the transactions contemplated hereby, including the
Company Acquisition Case.  Notwithstanding the foregoing or any other provision
of this Agreement, nothing in this Section 4.3 shall limit a party's right to
terminate this Agreement pursuant to 7.1(a)(iii) so long as such party has up to
then complied in all material respects with its obligations under this Section
4.3.

          (d)  Each party hereby agrees, while this Agreement is in effect, and
except as contemplated hereby, not to intentionally and knowingly take any
action with the intention and knowledge that such action would make any of its
representations or warranties contained herein untrue or incorrect in any
material respect or have the effect of preventing or disabling it from
performing any of its obligations under this Agreement.

          4.4 PUBLIC ANNOUNCEMENTS.  Parent and Holdco Sub, on the one hand, and
the Partnership, the Partners and the Transferors, on the other hand, will
consult with each other before issuing any press release or making any SEC
filing or other public statement (including holding press conferences or analyst
calls) with respect to this Agreement or the transactions contemplated hereby
and, except as may be required by applicable law, court process or any listing
agreement with any national securities exchange, shall not issue any press
release, make any such SEC filing or other public statement prior to such
consultation and providing the Partnership, the Partners and the Transferors, on
the one hand, and Parent and Holdco Sub, on the other hand, as the case may be,
with a reasonable opportunity to comment thereon.

Closing (other than Liabilities arising out of the Transactions other than taxes
and losses arising under Section 16 of the Exchange Act) and not disclosed on
Schedule 3.2(e); PROVIDED, HOWEVER, that:

          (w)  notwithstanding the several but not joint nature of the
indemnification provided under this Section 6.2, each Partner shall be liable in
respect of any claim under this Article VI for up to 130% of such Partner's pro
rata share, calculated by reference to the number of shares of Company Class A
Common Stock (including shares issuable upon the exercise of the Warrants)
allocable to or owned by such Partner (the "PRO RATA SHARE"), of the aggregate
Losses in respect of such claim;

          (x)  no Partner shall have any liability under clauses (a) and (b)(i)
of this Section 6.2 unless the aggregate of all Losses relating thereto (other
than in connection with the second sentence of Section 3.2(b), Section 3.2(c),
Section 3.2(d) (other than the fourth and fifth sentences thereof), Section
3.2(e), the second sentence of Section 3.3(b), Section 3.3(c) and Section 3.4
(other than the fourth and fifth sentences thereof)) for which the Partners

and then only to the extent of such excess;

          (y)  no Partner shall have any liability in respect of any individual
item under clauses (a) and (b)(i) of this Section 6.2 (other than in connection
with the second sentence of Section 3.2(b), Section 3.2(c), Section 3.2(d)
(other than the fourth and fifth sentences thereof), Section 3.2(e), the second
sentence of Section 3.3(b), Section 3.3(c) and Section 3.4 (other than the
fourth and fifth sentences thereof)) where the Loss is less than $100,000 and

clauses (a) and (b)(i) of this Section 6.2 (other than in connection with the
second sentence of Section 3.2(b), Section 3.2(c), Section 3.2(d) (other than
the fourth and fifth sentences thereof, Section 3.2(e), the second sentence of
Section 3.3(b), Section 3.3(c) and Section 3.4 (other that the fourth and fifth
sentences thereof)) shall in no event exceed $15,000,000.

Each of Parent and Holdco Sub acknowledges and agrees that, should the Closing
occur, its sole and exclusive remedy with respect to any and all claims relating
to this Agreement and the transactions contemplated hereby (other than claims
of, or causes of action arising from, fraud, which shall not be subject to this
Article VI) shall be pursuant to the indemnification provisions set forth in
this Article VI.  Recovery by Parent and Holdco Sub from any Partner of amounts
in excess of a Partner's Pro Rata Share of any Loss shall be conditioned on
Parent and Holdco Sub having used reasonable efforts to obtain indemnification
from each of the Partners in accordance with their respective Pro Rata Shares,
including by pursuing appropriate legal proceedings against each of the
Partners.

                                                                             33

          6.3 LOSSES NET OF INSURANCE, ETC.  The amount of any Loss for which
indemnification is provided under this Article VI shall be net of any amounts
actually recovered by the party entitled to indemnification (the "INDEMNIFIED
PARTY") under insurance policies and, in the case of the Partners, under the
indemnification policies of the Company that are available to such indemnified
party with respect to such Loss (net of the cost of obtaining such recovery). 
Any Partner entitled to indemnification under insurance policies or under the
indemnification policies of the Company shall, at the request of Parent or
Holdco Sub, use its reasonable best efforts to obtain such indemnification under
such insurance policies or from the Company before seeking indemnification from
Parent or Holdco Sub, and any expenses incurred in connection therewith shall be
advanced by the party obligated to provide such indemnification (the
"INDEMNIFYING PARTY").  It is understood that the indemnification obligation of
Parent and Holdco Sub is secondary and supplemental to any indemnification by
the Company or under any insurance policy maintained for the benefit of the
indemnified party.  The indemnifying party shall not be relieved of its
obligation to advance fees and expenses to the indemnified party in accordance
with Section 6.5 (or to indemnify any indemnified person under this Article VI)
by reason of any claim under any insurance policy or under the indemnification
policies of the Company, but shall be entitled to receive, and the indemnified
party does hereby assign to the indemnifying party the right to receive, direct
payment of any recovery under any such claim.

          6.4 TERMINATION OF INDEMNIFICATION.  The obligations to indemnify and
hold harmless a party hereto (a) pursuant to Sections 6.1(a) and 6.2(a) shall
terminate when the applicable representation or warranty terminates pursuant to
Section 7.14 and (b) pursuant to the other clauses of Sections 6.1 and 6.2 shall
not terminate, except that the obligations of Parent and Holdco Sub pursuant to
Section 6.1(b)(ii) shall terminate upon a termination by either party pursuant
to Section 7.1(a), but only with respect to actions or omissions from and after
the time of such termination; PROVIDED, HOWEVER, that as to clause (a) above
such obligations to indemnify and hold harmless shall not terminate with respect
to any item as to which the Person to be indemnified or the related party
thereto shall have, before the expiration of the applicable period, previously
made a claim by delivering a notice of such claim (stating in reasonable detail
the basis of such claim) to the indemnifying party.

          6.5 PROCEDURES RELATING TO INDEMNIFICATION UNDER ARTICLE VI.

          (a) An indemnified party entitled to any indemnification in respect
of, arising out of or involving a claim or demand made by any Person against the
indemnified party (a "THIRD PARTY CLAIM") shall notify the indemnifying party in
writing, and in reasonable detail, of the Third Party Claim within 10 Business
Days after receipt by such indemnified party of written notice of the Third
Party Claim; PROVIDED, HOWEVER, that failure to give such notification shall not
affect the indemnification provided hereunder except to the extent the
indemnifying party shall have been actually and materially prejudiced as a
result of such failure (it being understood that the indemnifying party shall
not be liable for any expenses incurred during the period in which the
indemnified party failed to give notice).

          (b) If a Third Party Claim is made against an indemnified party, the
indemnifying party shall be entitled to participate in the defense thereof and,
if it so chooses and unconditionally acknowledges its obligation to indemnify
the indemnified party with respect to such Third Party Claim, to assume the
defense thereof with counsel selected by the indemnifying party and not
reasonably objected to by the indemnified party.  Should the indemnifying party
so 

<PAGE>

                                                                             34

elect to assume the defense of a Third Party Claim, the indemnified party shall
have the right to participate in the defense thereof and to employ counsel, at
its own expense, separate from the counsel employed by the indemnifying party
(except that, for any period following receipt of notice of any Third Party
Claim during which the indemnifying party has failed to assume the defense of
such claim, the indemnifying party shall pay such fees and expenses as
incurred), it being understood that the indemnifying party  shall control such
defense; PROVIDED, that the indemnifying party shall not take any action in the
conduct of such defense that would materially adversely affect the indemnified
party without the consent of the indemnified party.  The indemnified party shall
also have the right to employ no more than one separate counsel for all
indemnified parties (and no more than one local counsel in any jurisdiction
where it is reasonably necessary) not reasonably objected to by the indemnifying
party, at the expense of the indemnifying party, but only if:  (i) the use of
counsel chosen by the indemnifying party to represent the indemnified party or
parties would present such counsel with a conflict of interest, (ii) the actual
or potential defendants in any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or are in addition to those
available to the indemnifying party, (iii) the indemnifying party shall not have
employed counsel reasonably satisfactory to the indemnified party to represent
the indemnified party within a reasonable time after notice of the institution
of such action or (iv) the indemnifying party shall in writing authorize the
indemnified party to employ separate counsel at the expense of the indemnifying
party.

          (c) If the indemnifying party elects to assume the defense of any
Third Party Claim, all of the indemnified parties shall cooperate with the
indemnifying party in the defense or prosecution thereof.  Such cooperation
shall include (upon the indemnifying party's reasonable request) the provision
to the indemnifying party of existing records and information which are
reasonably relevant to such Third Party Claim, and making themselves (in the
case of individuals) and using reasonable best efforts to make their employees
and their Representatives, if any, available on a mutually convenient basis to
provide additional information and explanation of any material provided
hereunder, and to attend depositions, give testimony or otherwise appear at any
trial or hearing to the extent reasonably requested by the indemnifying party. 
Whether or not the indemnifying party shall have assumed the defense of a Third
Party Claim, the indemnifying party shall not admit any liability with respect
to, or settle, compromise or discharge, such Third Party Claim without the
indemnified party's prior written consent (which consent shall not be
unreasonably withheld).  If the indemnifying party shall have assumed the
defense of a Third Party Claim, the indemnified party shall agree to any
settlement, compromise or discharge of a Third Party Claim which the
indemnifying party may recommend and which by its terms obligates the
indemnifying party to pay the full amount of the liability in connection with
such Third Party Claim, which releases the indemnified party completely in
connection with such Third Party Claim, and which would not otherwise adversely
affect the indemnified party.

          (d) Notwithstanding the foregoing, the indemnifying party shall not be
entitled to assume the defense of any Third Party Claim (but shall be liable for
the reasonable fees and expenses of counsel incurred by the indemnified party in
defending such Third Party Claim, which fees and expenses the indemnifying party
shall pay as incurred in advance of the final disposition of such Third Party
Claim) if the Third Party Claim seeks an order, injunction or other equitable
relief or relief for other than money damages against the indemnified party
which 

<PAGE>

                                                                             35

the indemnified party reasonably determines, after conferring with its outside
counsel, cannot be separated from any related claim for money damages; PROVIDED,
HOWEVER, that the foregoing shall not apply to any Third Party Claim prior to
the Closing seeking to enjoin or otherwise prevent, prohibit or impede the
consummation of the Transactions, which Third Party Claim prior to the Closing
shall be defended jointly by the indemnifying party and the indemnified party,
it being understood and agreed that (i) only one counsel (plus only one local
counsel in any jurisdiction where it is reasonably necessary) shall be permitted
for all of the indemnified parties and (ii) if the parties cannot in good faith
agree on a particular matter, such dispute shall be resolved in good faith by
the indemnifying party, with a good faith effort to balance the interests of
both the indemnified parties and the indemnifying party.  If such equitable
relief or other relief portion of the Third Party Claim can be so separated from
that for money damages, the indemnifying party shall be entitled to assume the
defense of the portion relating to money damages.  In the event that the
indemnifying party is not permitted to assume the defense of any Third Party
Claim pursuant to this Section 6.5(d), the indemnified party shall not agree to
any settlement, compromise or discharge of such Third Party Claim which by its
terms obligates the indemnifying party to pay any monetary damages or otherwise
imposes any obligation on the indemnifying party without the prior written
consent of the indemnifying party.

          (e) In the event that the indemnified party is entitled to retain
counsel at the indemnifying party's expense in accordance with Section 6.5(b) or
Section 6.5(d), the indemnifying party shall reimburse the indemnified party for
the reasonable fees, costs and expenses of such counsel upon presentation of
invoices detailing with reasonable specificity the nature of the services
provided and the basis of the fees, costs and expenses incurred.

          6.6 OTHER CLAIMS.  In the event any indemnified party should have a
claim against any indemnifying party under Section 6.1 (other than Section
6.1(b)(ii)) or 6.2 that does not involve a Third Party Claim, the indemnified
party shall deliver notice of such claim (stating with reasonable specificity
the basis and amount of the claim) with reasonable promptness to the
indemnifying party.

          6.7 ARBITRATION.  In the event that any parties are unable to resolve
any dispute as to whether an indemnified party is entitled to indemnification
hereunder and/or the amount of the related claim, the exclusive method for
resolving such dispute shall be binding, nonappealable arbitration in New York,
New York initiated by a party by a written notice to the other party demanding
arbitration and specifying the claim to be arbitrated.  Such arbitration shall
be conducted pursuant to the Expedited Procedures of the Commercial Arbitration
Rules ("RULES") of the American Arbitration Association ("AAA"), with the
following modifications.  The party initiating arbitration (the "CLAIMANT")
shall appoint its arbitrator in its request for arbitration (the "REQUEST"). 
The other party (the "RESPONDENT") shall appoint its arbitrator within 15
Business Days of receipt of the Request and shall notify the Claimant of such
appointment in writing.  If the Respondent fails to appoint an arbitrator within
such 15 Business Day period, the arbitrator named in the Request shall decide
the controversy or claim as a sole arbitrator.  Otherwise, the two arbitrators
appointed by the parties shall appoint a third arbitrator within 15 Business
Days after the Respondent has notified Claimant of the appointment of the
Respondent's arbitrator.  When the third arbitrator has accepted the
appointment, the two party-appointed arbitrators shall promptly notify the
parties of such appointment.  If the two arbitrators appointed by the parties
fail or are unable to so appoint a third arbitrator, then the appointment of the
third arbitrator shall be made by the AAA, which shall promptly notify the
parties of the appointment.  The third

                                                                             36

arbitrator shall act as chairperson of the panel.  Upon appointment of the third
arbitrator, the arbitrators shall proceed to commence and conduct all
proceedings promptly and in accordance with the Rules.  The arbitral award shall
be in writing and shall be final and binding on the parties to the arbitration. 
The arbitrator shall be instructed to award costs, including reasonable
attorneys' fees and disbursements, which shall be paid by the party against whom
the award is entered.  Judgment upon the award may be entered by any court
having jurisdiction thereof or having jurisdiction over the parties or their
assets, without review of the merits of the award,  in accordance with Section
7.11.

     conversion, exercise or exchange of securities outstanding on the date of
     this Agreement that are convertible into or exercisable or exchangeable for
     shares of Company Common Stock) or (B) any securities convertible into or
     exercisable or exchangeable for shares of Company Common Stock which result

Agreement and no waiver of any provision of or default under this Agreement

     and enforcement of any judgment in respect thereof, to the non-exclusive
     general jurisdiction of the courts of the United States of America sitting
     in the Southern District of New York or, in the absence of Federal
     jurisdiction, the Commercial Part of the Supreme Court of the State of New
     York for New York County;

          (b) consents that any such action or proceeding may be brought in such
     courts and waives any objection that it may now or hereafter have to the
     venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (c) agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     address for notices to it set forth in Section 7.4; and

          (d) agrees that nothing herein shall affect the right to effect

interests of the other parties hereto, and (ii) the other parties hereto would
be irreparably damaged in the event any of the provisions of this Agreement were
not performed in accordance with their specific terms or were otherwise
breached.  It is accordingly agreed that the parties hereto shall be entitled to
preliminary and permanent injunctive relief to prevent breaches of the
provisions of this Agreement by the other parties hereto without the necessity
of proving irreparable injury or actual damages or of posting any bond, and to
enforce specifically the terms and provisions hereof and thereof, which rights
shall be cumulative and in addition to any other remedy to which the parties
hereto may be entitled hereunder or at law or equity.

          7.13 FURTHER ASSURANCES.  From time to time, at the reasonable request
of any other party hereto and without further consideration, each party hereto
shall execute and deliver such additional documents and take all such further
action as may be necessary to consummate and make effective, in the most
expeditious manner practicable, the transactions contemplated by this Agreement.

                                                                     EXHIBIT 2.2



                                 GOVERNANCE AGREEMENT


          Agreement dated as of January 25, 1998, among Continental Airlines,
Inc., a Delaware corporation (the "Company"), Newbridge Parent Corporation, a
Delaware corporation (the "Stockholder"), and Northwest Airlines Corporation, a
Delaware corporation that is the holder of all of the outstanding stock of the
Stockholder ("Parent").

          WHEREAS, the Parent, the Stockholder and Air Partners, L.P., a Texas
limited partnership ("AP"), propose to enter into an Investment Agreement (the
"Investment Agreement") dated as of the date hereof, to which the Company is not
a party and, pursuant to which, among other things, and subject to the terms and
conditions to be contained in the Investment Agreement, the Stockholder would
acquire the outstanding interests in AP and the shares of Class A Common Stock,
par value $.01 per share ("Class A Common Stock"), held by certain affiliates of
AP resulting in its Beneficial Ownership of 8,535,868 shares of Class A Common
Stock of the Company (the "Stock Purchase"), and

          WHEREAS, Northwest Airlines, Inc., an indirect wholly owned subsidiary
of Parent, and the Company have negotiated a Master Alliance Agreement (the
"Alliance Agreement") dated as of the date hereof and the Company has
conditioned its entering into the Alliance Agreement on the Parent and the
Stockholder entering into this Agreement with the Company. 

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein, and intending to be legally bound
hereby, the Company, the Parent and the Stockholder hereby agree as follows:

                                      SECTION 1
                                STANDSTILL AND VOTING

          Section 1.01.  ACQUISITION OF VOTING SECURITIES.

          (a)  Until the Standstill Termination Date, the Parent and the
Stockholder each covenant and agree that they and their respective Affiliates
will not Beneficially Own any Voting Securities in excess of the Permitted
Percentage; PROVIDED that if any of the following events shall occur:  (A) it is
publicly disclosed that Voting Securities representing 15% or more of the Total
Voting Power have been acquired subsequent to the date hereof by any Person or
13D Group (other than (1) any Subsidiary of the Company, any employee benefit
plan of the Company or of any of its Subsidiaries or any Person holding Voting
Securities for or pursuant to the terms of any such employee benefit plan) or
(2) the Parent or the Stockholder, or an Affiliate of, or any Person acting in
concert with, the Parent or the Stockholder, or any Person that has been
induced, in whole or in part, directly or indirectly, by the Parent, the
Stockholder or the Voting Trust to make such acquisition), or (B) a bona fide
tender or exchange offer is made by any Person (other than the Company, the
Parent, the Stockholder, or an Affiliate of, or any Person acting in concert
with, or induced by, directly or indirectly, any of them) to purchase
outstanding shares of Voting Securities representing 15% or more of the Total
Voting Power and such offer is not withdrawn or terminated prior to the
Stockholder acquiring additional Voting Securities, or (C) the Board of
Directors shall approve the acquisition by any Person or 13D 

<PAGE>

Group of Voting Securities that would otherwise trigger the adverse consequences
of any stockholder rights plan of the Company that may at the time be in effect,
then in any event referred to in clauses (A), (B) or (C) above, notwithstanding
the foregoing provisions of this Section 1.01(a) or any other provisions of this
Agreement, the Parent, the Stockholder and their Affiliates may acquire
additional Voting Securities in any manner, whether in market purchases,
privately negotiated transactions, a tender or exchange offer on any terms or in
any other manner, and the Parent or the Stockholder may submit a competing
proposal or a proposal for a merger or any other type of business combination.

          (b)  Notwithstanding the provisions of Section 1.01(a), following the
Closing and until the Standstill Termination Date, the Stockholder may purchase
shares of Voting Securities in any manner in order to maintain at the Permitted
Percentage its percentage of the Fully Diluted Voting Power.

          (c)  Except as expressly provided herein, the Parent and the
Stockholder shall not permit any Affiliate to Beneficially Own any Voting
Securities in excess of the Permitted Percentage.

          (d)  Except as set forth in the next sentence, if at any time the
Parent or the Stockholder becomes aware that it and its Affiliates Beneficially
Own more than the Permitted Percentage, then the Parent shall promptly notify
the Company, and the Parent and the Stockholder, as appropriate, shall promptly
take all action necessary to reduce the amount of Voting Securities Beneficially
Owned by such Persons to an amount not greater than the Permitted Percentage. 
If Voting Securities Beneficially Owned by the Stockholder and its Affiliates
exceed the Permitted Percentage (i) solely by reason of repurchases of Voting
Securities by the Companyor (ii) as a result of the transactions otherwise
permitted by the terms of this Agreement, then the Stockholder shall not be
required to reduce the amount of Voting Securities Beneficially Owned by such
Persons and the percentage of the Fully Diluted Voting Power represented by the
Voting Securities Beneficially Owned by such Persons shall become the Permitted
Percentage.

          Section 1.02.  RESTRICTIONS ON TRANSFER.  Prior to the Standstill
Termination Date, neither the Stockholder nor the Parent will Transfer or permit
any of their respective Affiliates to Transfer any Voting Securities except for:
(i) Transfers of Voting Securities pursuant to any tender or exchange offer to
acquire Voting Securities approved and recommended by the Company's Board of
Directors (which recommendation has not been withdrawn); (ii) Transfers of
Voting Securities to the Stockholder provided that such Voting Securities are
immediately transferred to the public stockholders of the Stockholder by means
of a PRO RATA dividend or other PRO RATA distribution; (iii) Transfers of Voting
Securities by the Stockholder to any of its controlled Affiliates, provided that
such Affiliate agrees to be bound by the provisions of this Agreement applicable
to the Stockholder; (iv) Transfers of the Shares by the Voting Trust to the
Stockholder upon termination of the Voting Trust; (v) Transfers of Voting
Securities by the Stockholder pursuant to Section 4.1(d) of the Investment
Agreement or Section 5 of this Agreement; and (vi) Transfers of Voting
Securities by the Stockholder to any transferee who, together with its
Affiliates and Associates, would not, to the knowledge of Parent or the
Stockholder, Beneficially Own in excess of 10% of the Voting Power as a result
of such 

                                          2
<PAGE>

Transfer; PROVIDED that no such Transfers under clauses (i) or (iii) of this
Section 1.02 may be made to any Person (including such Person's Affiliates and
any Person or entities which are part of any 13D Group which includes such
transferee or any of its Affiliates) that, after giving effect to such Transfer,
would to the knowledge of Parent or the Stockholder Beneficially Own Voting
Securities representing more than 10% of the Total Voting Power.

          Section 1.03.  VOTING TRUST.  Immediately following the Closing, the
Stockholder and the Parent shall cause AP to deposit the Shares, and the
Stockholder and the Parent shall deposit any other shares of Voting Securities
Beneficially Owned by either of them or any of their Affiliates, into a voting
trust (the "Voting Trust") to be established pursuant to a voting trust
agreement (the "Voting Trust Agreement") with an independent voting trustee in a
form reasonably satisfactory to Parent and the Company and which shall include
the following provisions for the voting of the shares of Voting Securities
deposited therein:  until the Standstill Termination Date, all such shares shall
(a) be voted or consented on all matters submitted to a vote of the Company's
stockholders, other than the election of directors, at the option of the
Stockholder, either (i) as recommended by the Board of Directors or (ii) (A) in
the case of votes at a stockholders meeting, in the same proportion as the votes
cast by other holders of Voting Securities, and (B) in the case of consents, so
that the percentage of Stockholder Voting Power consented to on any matter
equals the percentage of all other outstanding Voting Securities so consented;
PROVIDED, that with respect to (x) any vote on a merger, reorganization, share
exchange, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company, any sale of all or
substantially all of the Company's assets or any issuance of Voting Securities
that would represent in excess of 20% of the Voting Power prior to such
issuance, including any of the foregoing involving the Stockholder or the
Parent, or (y) any amendment to the Company's amended and restated certificate
of incorporation or by-laws that would materially and adversely affect the
Stockholder (including through its effect on the Alliance Agreement and the
rights of the Voting Securities Beneficially Owned by the Stockholder), such
shares may be voted as directed by the Stockholder and (b) in the election of
directors, for the election of the Independent Directors nominated by the Board
of Directors of the Company determined by a Majority Vote; PROVIDED, that with
respect to any election of directors in respect of which any Person other than
the Company is soliciting proxies, the Stockholder and the Parent shall cause
all such shares to be voted, at the option of the Stockholder, either (i) as
recommended by the Board of Directors or (ii) in the same proportion as the
votes cast by the other holders of Voting Securities.  The Voting Trust
Agreement shall also provide that the Voting Trust shall not issue voting trust
certificates or any interest in the Voting Trust to a Person other than the
Stockholder or any of its Affiliates.

          Section 1.04.  FURTHER RESTRICTIONS ON CONDUCT.  The Parent and the
Stockholder, as applicable, covenant and agree that until the Standstill
Termination Date:

          (a)  except by virtue of the Stockholder's representation on the Board
of Directors of the Company, if any, in connection with the performance of the
Alliance Agreement and the subsequent negotiations and agreements contemplated
thereby, neither the Parent, the Stockholder nor any of their respective
Affiliates will otherwise act, alone or in concert with others, to seek to
affect or influence the Board of Directors or the control of the management of
the Company or the businesses, operations, affairs, financial matters or
policies of the Company 

                                          3
<PAGE>

(it being agreed that this paragraph shall not prohibit the Parent and its
Subsidiaries, and their respective employees from engaging in ordinary course
business activities with the Company);

          (b)  other than in connection with the deposit of the Shares and other
Voting Securities into the Voting Trust as required by Section 1.03, the
Stockholder shall not deposit any Voting Securities into any voting trust or
subject any Voting Securities to any proxy (other than any revocable proxy to
vote the Shares in a manner consistent with Sections 1.03 and 2.01 hereof),
arrangement or agreement with respect to the voting or consenting with respect
to such Voting Securities or other agreement having similar effect;

          (c)  neither the Parent, the Stockholder nor any of their respective
Affiliates shall initiate or propose any stockholder proposal or action or make,
or in any way participate in or encourage, directly or indirectly, any
"solicitation" of "proxies" to vote or written consents, or seek to influence
any Person with respect to the voting of or consenting with respect to, any
Voting Securities, or become a "participant" in a "solicitation" (as such terms
are defined in Regulation 14A under the Exchange Act, as in effect on the date
hereof) in any election contest with respect to the election or removal of the
Independent Directors or in opposition to the recommendation of the majority of
the directors of the Company with respect to any other matter;

          (d)  other than as is contemplated by this Agreement, neither the
Parent, the Stockholder, the Voting Trust nor any of their respective Affiliates
shall join a partnership, limited partnership, syndicate or other group, or
otherwise act in concert with any other Person, for the purpose of acquiring,
holding, voting or disposing of Voting Securities, or, otherwise become a
"person" within the meaning of Section 13(d)(3) of the Exchange Act;

          (e)  neither the Parent nor the Stockholder shall transfer its
partnership interests in AP, nor cause or permit AP to admit new partners;

          (f)  each of the Parent and the Stockholder shall, and shall cause its
Affiliates to, deposit into the Voting Trust such additional shares of Voting
Securities as they may acquire after the Closing; and

          (g)  neither the Parent nor the Stockholder nor any of their
respective Affiliates shall take any action inconsistent with the foregoing;

PROVIDED that the restrictions set forth in Sections 1.04 (a), (b), (c) and (d)
of this Agreement shall not apply to (i) any vote by the Parent or the
Stockholder described in clauses (x), (y) or (z) of Section 1.03 of this
Agreement, (ii) any Stockholder Designee acting in his or her capacity as a
director of the Company, (iii) Northwest Airlines, Inc. acting as an alliance
partner pursuant to the Alliance Agreement, (iv) the Parent or the Stockholder
seeking a merger with the Company following the Company's delivery of a
Termination Notice pursuant to Section 21 of the Alliance Agreement or (v) any
action taken as permitted by Section 1.01(a).

          Section 1.05  REPORTS.  During the term of this Agreement, the
Stockholder shall deliver to the Company, promptly after any Transfer of Voting
Securities by the Stockholder, the Voting Trust or their respective Affiliates,
an accurate written report specifying the amount and

                        BOARD OF DIRECTORS AND RELATED MATTERS

          Section 2.01.  COMPOSITION OF BOARD OF DIRECTORS.

          (a)  Immediately after the consummation of the Stock Purchase (the
"Closing"), the Board of Directors shall take such corporate actions as are
necessary to cause an individual designated by the Stockholder and reasonably
acceptable to the Board of Directors, which designee shall not be an officer or
an employee of the Parent, the Stockholder or the Company or any of their
respective Affiliates, or any person who shall have served in any such capacity
within the three-year period immediately preceding the date such determination
is made (the "Stockholder Designee"), to be appointed to the Board of Directors.
The directors comprising the Board of Directors immediately after the Closing
shall be otherwise unchanged from those as of the date of this Agreement, and
the individuals listed on Exhibit 2.01 hereto shall, for the purposes of this
Agreement, constitute the Independent Directors at such time.

          (b)  Following the Closing and until the Standstill Termination Date,
the Company, the Parent, the Stockholder and their respective Affiliates shall
take all such actions as are required under applicable law to cause Independent
Directors to constitute at all times at least a majority of the Board of
Directors.  At each annual meeting of stockholders of the Company following the
Closing, or at any time that a vacancy in a seat previously occupied by an
Independent Director on the Board of Directors is to be filled, the identity of
the Independent Director or Directors to stand for election to the Board of
Directors or to fill the vacancy, as the case may be, shall be determined by a
Majority Vote.

          (c)  Following the Closing and until the Standstill Termination Date,
upon the death, resignation or disability of any Stockholder Designee, the
Company shall take all such corporate actions as are necessary to cause a
successor individual designated by the Stockholder and reasonably acceptable to
the Board of Directors of the Company by a Majority Vote, which designee shall
not be an officer or an employee of the Parent, the Stockholder or the Company
or any of their respective Affiliates, or any person who shall have served in
any such capacity within the three-year period immediately preceding the date
such determination is made, to be appointed to the Board of Directors.

          (d)  Without the prior written consent of the Parent, the Company
shall not amend, alter or repeal its amended and restated certificate of
incorporation or by-laws so as to eliminate or diminish the ability of
stockholders of the Company to act by written consent or Section 1.10 of the
Company's by-laws.

          Section 2.02.  TRANSACTIONS INVOLVING THE STOCKHOLDER.  The parties
agree that any material transaction between the Company and the Parent, the
Stockholder or any of their respective Affiliates, or relating to this Agreement
or the Alliance Agreement, including without limitation, any amendment,
modification or waiver of any provision hereof or thereof, shall not be taken
without the prior approval thereof by a Majority Vote.

          Section 2.03.  SIGNIFICANT ACTIONS.  Promptly following the Closing,
the Company shall amend its by-laws to provide that no action described in
Exhibit 2.03 hereto may be taken without prior approval thereof by a Majority
Vote.

          Section 2.04.  MANAGEMENT OF THE BUSINESS.  Following the Closing and
until the Standstill Termination Date, except as indicated in Section 2.02
above, management of the Company will continue to have full authority to operate
the day-to-day business affairs of the Company to the same extent as prior to
the Closing.  In this regard, the Chief Executive Officer of the Company shall
continue to be in charge of all matters within his authority on the date hereof,
subject, as required by Delaware law, to the requirement that the business and
affairs of the Company shall be managed by or under the direction of the Board
of Directors.

          Section 2.05.  EXECUTIVE COMMITTEE.  Prior to the Closing, the Company
shall cause the authority of the Executive Committee of the Company's Board of
Directors to be modified to the reasonable satisfaction of the Parent, to permit
such committee to approve only ordinary course transactions in which the Company
engages from time to time, but which nonetheless require approval by the Board
of Directors.

                                      SECTION 3
                                      COVENANTS

          Section 3.01.  LEGENDS.  The Company shall cooperate and instruct its
transfer agent and registrar to place legends on all shares of Class A Common
Stock (and the Warrants) held by AP or any of its Affiliates to reflect that
such shares are subject to the restrictions on voting and transfer set forth in
the Investment Agreement and in this Agreement.

          Section 3.02.  ISSUANCE OF CLASS A COMMON STOCK.  The Company shall
not issue any additional shares of Class A Common Stock (except upon exercise of
the Warrants outstanding as of the date hereof) or securities convertible into
or exercisable or exchangeable for shares of Class A Common Stock or enter into
any agreement or arrangement to do the same without giving the Stockholder pre-
emptive rights which shall permit the Stockholder to acquire shares of Class A
Common Stock concurrently with any such issuance.

          Section 3.03.  ISSUANCE OF CLASS B COMMON STOCK.  The Company shall
not, without giving the Stockholder pre-emptive rights, issue shares of Class B
Common Stock, par value $.01 per share, of the Company (the "Class B Common
Stock"), or securities convertible into or exercisable or exchangeable for
shares of Class B Common Stock except to the extent that such shares (including
underlying shares, in the case of securities convertible into or exercisable or
exchangeable for shares of Class B Common Stock) (a) in the case of such shares
or convertible securities issued for the purpose of fulfillment of the Company's
obligations under 

                                          6
<PAGE>

any present or future stock option plan, do not exceed the number of shares
issued under such plans consistent with past practices, (b) in the case of such
shares or convertible securities issued for any other purpose, do not exceed in
the aggregate 5% of the outstanding shares of Class B Common Stock on the date
of the Investment Agreement or (c) are issued pursuant to options, warrants or
convertible securities issued and outstanding on, or commitments to issue such
shares that are in effect on, the date hereof and which are disclosed in Section
4.01(b).

          Section 3.04.  CONVERSION; INTERESTED STOCKHOLDERS.  The Company shall
not seek a vote of its stockholders, approving any amendment to the Company's
amended and restated certificate of incorporation or by-laws, nor shall it take
any other action, that would, without the consent of the Parent, (a) eliminate
AP's right in Section 2(e) of the Company's amended and restated certificate of
incorporation to convert shares of Class A Common Stock into shares of Class D
Common Stock, par value $.01 per share, (b) cause Section 203 of the Delaware
General Corporation laws to be applicable to the Company or (c) adopt an
"interested stockholders" provision.

          Section 3.05.  TRANSFER OF VOTING TRUST CERTIFICATES.  Prior to the
Standstill Termination Date, the Stockholder shall not Transfer the voting trust
certificates issued to it by the Voting Trust or any interest in the Voting
Trust represented thereby.

          Section 3.06.  CONDUCT.  Each of the Company, the Parent and the
Stockholder agrees that from the date hereof until the Closing, except as
otherwise contemplated by this Agreement or with the prior written consent of
the other, it and its subsidiaries shall not (a) change its principal line of
business, (b) change the fundamental nature of its business or (c) dispose of
any substantial portion of its assets.

          Section 3.07.  NO SOLICITATION.  

          (a)  From the date hereof until the Closing, the Company and its
subsidiaries, and the officers, directors, financial or legal advisors of the
Company and its subsidiaries will not, directly or indirectly, (i) take any
action to solicit, initiate or encourage any Acquisition Proposal or (ii) engage
in negotiations with, or disclose any nonpublic information relating to the
Company or any of its subsidiaries or afford access to the properties, books or
records of the Company or any of its subsidiaries to, any person that may be
considering making, or has made, an Acquisition Proposal; PROVIDED that, the
Company may, in response to an unsolicited written proposal from a third party
regarding an Acquisition Proposal engage in the activities specified in clause
(ii), if the Board of Directors of the Company determines in good faith, after
obtaining and taking into account the advice of outside counsel, that such
action is required for the Board of Directors of the Company to comply with its
fiduciary duties under applicable law.  The Company will promptly (and in no
event later than 24 hours after having received the relevant Acquisition
Proposal) notify the Parent (which notice shall be provided orally and in
writing and shall identify the person making the Acquisition Proposal and set
forth the material terms thereof) after having received any Acquisition
Proposal, or request for nonpublic information relating to the Company or any of
its subsidiaries or for access to the properties, books or records of the
Company or any of its subsidiaries by any person who is considering making or
has made an Acquisition Proposal.  The Company will, to the extent consistent
with the fiduciary duties of 

                                          7
<PAGE>

the Company's Board of Directors under applicable law, keep the Parent fully
informed of the status and details of any such Acquisition Proposal or request. 
The Company shall, and shall cause its subsidiaries, and shall instruct the
directors, officers and financial and legal advisors of the Company and its
subsidiaries to, cease immediately and cause to be terminated all activities,
discussions or negotiations, if any, with any persons conducted heretofore with
respect to any Acquisition Proposal.  Notwithstanding any provision of this
Section, nothing in this Section shall prohibit the Company or its Board of
Directors from taking and disclosing to the Company's stockholders a position
with respect to an Acquisition Proposal by a third party to the extent required
under the Exchange Act or from making such disclosure to the Company's
stockholders which, in the judgment of the Board of Directors, taking into
account the advice of outside counsel, is required under applicable law;
PROVIDED that nothing in this sentence shall affect the obligations of the
Company and its Board of Directors under any other provision of this Agreement.

          (b)  From the date hereof until the Closing, the Parent and its
subsidiaries, and the officers, directors, financial or legal advisors of the
Parent and its subsidiaries will not, directly or indirectly, (i) take any
action to solicit, initiate or encourage any Acquisition Proposal or (ii) engage
in negotiations with, or disclose any nonpublic information relating to the
Parent or any of its subsidiaries or afford access to the properties, books or
records of the Parent or any of its subsidiaries to, any person that may be
considering making, or has made, an Acquisition Proposal; PROVIDED that, the
Parent may, in response to an unsolicited written proposal from a third party
regarding an Acquisition Proposal engage in the activities specified in clause
(ii), if the Board of Directors of the Parent determines in good faith, after
obtaining and taking into account the advice of outside counsel, that such
action is required for the Board of Directors of the Parent to comply with its
fiduciary duties under applicable law.  The Parent will promptly (and in no
event later than 24 hours after having received the relevant Acquisition
Proposal) notify the Company (which notice shall be provided orally and in
writing and shall identify the person making the Acquisition Proposal and set
forth the material terms thereof) after having received any Acquisition
Proposal, or request for nonpublic information relating to the Parent or any of
its subsidiaries or for access to the properties, books or records of the Parent
or any of its subsidiaries by any person who is considering making or has made
an Acquisition Proposal.  The Parent will, to the extent consistent with the
fiduciary duties of the Parent's Board of Directors under applicable law, keep
the Company fully informed of the status and details of any such Acquisition
Proposal or request.  The Parent shall, and shall cause its subsidiaries, and
shall instruct the directors, officers and financial and legal advisors of the
Parent and its subsidiaries to, cease immediately and cause to be terminated all
activities, discussions or negotiations, if any, with any persons conducted
heretofore with respect to any Acquisition Proposal.  Notwithstanding any
provision of this Section, nothing in this Section shall prohibit the Parent or
its Board of Directors from taking and disclosing to the Parent's stockholders a
position with respect to an Acquisition Proposal by a third party to the extent
required under the Exchange Act or from making such disclosure to the Parent's
stockholders which, in the judgment of the Board of Directors, taking into
account the advice of outside counsel, is required under applicable law;
PROVIDED that nothing in this sentence shall affect the obligations of the
Parent and its Board of Directors under any other provision of this Agreement.

                            REPRESENTATIONS AND WARRANTIES

          Section 4.01.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  (a) 
The Company represents and warrants to the Parent and the Stockholder that (i)

standing under the laws of the State of Delaware and has the corporate power and

          Section 4.02.  REPRESENTATIONS AND WARRANTIES OF THE PARENT. The
Parent represents and warrants to the Company that (a) it and the Stockholder
are corporations duly organized, validly existing and in good standing under the
laws of the State of Delaware and each has the power and authority to enter into
this Agreement and to carry out its respective obligations hereunder, (b) the
execution and delivery of this Agreement by the Parent and the Stockholder and
the consummation thereby of the transactions contemplated hereby have been duly
authorized by all necessary action on their parts and no other proceedings on
their parts are necessary to authorize this Agreement or any of the transactions
contemplated hereby, and (c) this Agreement has been duly executed and delivered
by the Parent and the Stockholder and constitutes a valid and binding obligation
of each of them, and is enforceable against each of them in accordance with its
terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent transfer and other similar laws affecting creditors' rights generally
from time to time in effect and to general principles of equity, including
concepts of materiality, reasonableness, good faith and fair dealing, regardless
of whether in a proceeding at equity or at law).

                                      SECTION 5
                          TERMINATION OF ALLIANCE AGREEMENT

          Section 5.01.  STOCKHOLDER'S ELECTION.  Within thirty (30) days
following the delivery by the Company of a Termination Notice pursuant to
Section 21(a) of the Alliance Agreement, the Parent shall make an election (an
"Election") of either the merger procedures specified in Section 5.02 (the
"Merger Procedures") or the stock sale procedure specified in Section 5.03 (the
"Stock Sale Procedure") by delivering to the Company a Notice of Election. If
the Stockholder initially elects the Merger Procedure (a "Merger Election"), it
may at any time prior to the execution by the Parent and the Company of a
definitive agreement for a merger transaction, upon written notice to the
Company, irrevocably elect to abandon the Merger Procedure and elect the Stock
Sale Procedure, in which latter event the Parent shall have 18 months following
its election of the Stock Sale Procedure to consummate the sale of its shares. 
If the Stockholder initially elects the Stock Sale Procedure (the "Stock Sale
Election"), it may not, at any time thereafter, make a Merger Election. If the
Stockholder fails timely to make an Election, it shall be deemed to have made a
Stock Sale Election.

          Section 5.02.  MERGER PROCEDURE.  (a)  If the Stockholder makes a
Merger Election, it shall within 30 days after doing so submit a notice to the
Company setting forth the material terms and conditions upon which it would
propose to acquire the Voting Securities not Beneficially Owned by it and its
Affiliates (the "Merger Proposal").  After the Merger Election, the Company
shall promptly establish a committee of the Board of Directors (the "Special
Committee") composed of only, and at least three (3), Independent Directors as
determined by a Majority Vote, which shall have the authority to consider,
review, and negotiate the terms of, and to make a recommendation to the full
Board of Directors regarding, the Merger Proposal, and to retain, at the
Company's expense, counsel, financial advisors and other advisors, and to take
such other actions customarily delegated to a committee of independent directors
in similar circumstances.  If the Stockholder submits a Merger Proposal, the
Stockholder and the Special Committee shall negotiate in good faith and use
their best efforts to agree upon the terms of a merger at the earliest
practicable date consistent with the Special Committee's fiduciary duties.

                                          10
<PAGE>

          (b)  (i)  If the Stockholder and the Company do not enter into a
definitive merger agreement within six (6) months of the establishment of the
Special Committee, on the third day after the six month anniversary of the
establishment of the Special Committee (the "Initiation Date"), the Company will
designate an investment banking firm of recognized national standing (the
"Company's Appraiser") and the Stockholder will designate an investment banking
firm of recognized national standing (the "Parent's Appraiser"), in each case to
determine the "Merger Value".  The Stockholder acknowledges and agrees that the
consideration that would constitute the Merger Value is the price per share of
Voting Securities that an unrelated third party would pay if it were to acquire
all outstanding shares of Voting Securities (other than the shares held by the
Stockholder and its Affiliates) in one or more arm's-length transactions,
assuming that the Shares were being sold in a manner designed to attract all
possible participants.  Each of the investment banking firms referred to herein
will be instructed to determine the Merger Value in this manner.

          (ii)  Within thirty (30) days after the Initiation Date, the Company's
Appraiser and the Parent's Appraiser will each determine its initial view as to
the Merger Value and consult with one another with respect thereto.  By the 45th
day after the Initiation Date, the Company's Appraiser and the Parent's
Appraiser will each have determined its final view as to the Merger Value.  At
that point, if the Higher Appraised Amount (as defined below) is not more than
110% of the Lower Appraised Amount (as defined below), the Merger Value will be
the average of those two views.  Otherwise, the Company's Appraiser and the
Parent's Appraiser will agree upon and jointly designate a third investment
banking firm of recognized national standing (the "Mutually Designated
Appraiser") to determine its view of the Merger Value.  The Mutually Designated
Appraiser will not be permitted to see or otherwise have access to, or be
informed of, the results of the appraisals of Merger Value by the Company's
Appraiser and the Parent's Appraiser, or any component of either appraiser's
analysis which led to its conclusions, and each of the Parent and the Company
agree to comply with the foregoing provision.  The Mutually Designated appraiser
will, no later than the 65th day after the Initiation Date, determine the Merger
Value (the "Mutually Appraised Amount").  The Merger Value will be (x) the
Mutually Appraised Amount, if such amount falls within the range of values that
is between the Lower Appraised Amount and the Higher Appraised Amount, (y) the
Lower Appraised Amount if such amount is below the Lower Appraised Amount, and
(z) the Higher Appraised Amount if such amount is above the Higher Appraised
Amount.

          As used herein, "Lower Appraised Amount" means the lower of the
respective final views of the Company's Appraiser and the Parent's Appraiser as
to the Merger Value and "Higher Appraised Amount" means the higher of such
respective final views.

          The Company and the Parent shall be responsible for the payment of
fees and expenses to the respective investment banking firms designated by them,
and shall each be responsible for 50% of the fees and expenses payable to the
Mutually Designated Appraiser.

          (iii)     If, within fifteen (15) days of the determination of the
Merger Value as provided above (such fifteenth day being referred to as the
"Trigger Date"), (A) the Stockholder is unwilling to enter into a definitive
merger agreement at the Merger Value, then the Stockholder shall be required to
dispose of the shares of Voting Securities Beneficially Owned 

                                          11
<PAGE>

by it and its Affiliates pursuant to the Stock Sale Procedure within eighteen
(18) months of the Trigger Date or (B) the Company's Board of Directors and the
Special Committee are unwilling to approve and recommend a definitive merger
agreement at the Merger Value, then the provisions of this Agreement (other than
Section 7) shall terminate in all respects.

          5.03.  STOCK ELECTION PROCEDURE.  (a) If the Stockholder makes a Stock
Sale Election, then it shall, within twenty-four (24) months of the delivery of
the Termination Notice, sell the shares of Voting Securities Beneficially Owned
by it and its Affiliates (the "Selling Stockholders"), at its option, either
(i) in one or a series of privately negotiated sales of 15% or more of Voting
Securities Beneficially Owned by the Selling Stockholders (each, a "Private
Sale" and together, "Private Sales") or (ii) in any other manner that the
Selling Stockholders elect in their sole discretion.


          (b)  Each Selling Stockholder shall give the Company fifteen (15)
days' prior written notice of its intention to effect a Private Sale, which
notice (a "Sales Notice") shall include the material terms and conditions of the
Private Sale, the date that the sale is expected to close, and the proposed
purchaser or purchasers.  A Sales Notice given with respect to a Private Sale
shall also include a certification by such Stockholder that the Private Sale
described therein is to a BONA FIDE purchaser who such Stockholder reasonably
believes has the financial resources to complete the sale and would not be
prohibited by law or regulation from doing so.

          (c)  The Company may, by action of its Board of Directors upon a
Majority Vote, by notice to such Stockholder given not more than twenty (20)
days after the Sales Notice, reject a Private Sale (or a series of
contemporaneous Private Sales) based upon its good faith determination that the
sale or sales to such prospective purchaser (or purchasers) would be injurious
to the interests of the Company and the holders of the Company's Voting
Securities (other than such Stockholder and its Affiliates) by virtue of the
prior business practices of such prospective purchaser or purchasers, it being
understood in that regard that the fact that such purchaser is an airline or is
affiliated with an airline shall not be the basis for any such determination nor
shall the fact that the Board of Directors concludes that wide dispersal of the
ownership of Voting Securities is in the best interests of the Company's
stockholders.  Upon receiving notice of such determination, the Stockholder and
its Affiliates shall terminate discussions with such prospective purchaser or
purchasers.  The Company's right to reject a purchaser (or purchasers) under
this Section shall be exercised only once and, upon its exercise, the Company
shall have no such further rights.

(each, if any, a "PARENT OPTION") and (ii) any award of phantom stock units
issued under Parent's 1996 Retention and Long Term Incentive Compensation Plan
and Agreement Evidencing Grant of Phantom Stock Units to John H. Dasburg (each,
if any, a "PARENT AWARD"), and the due exercise of rights under (i) any such
Parent Option shall entitle the holder thereof to acquire, upon the same terms
and conditions that were applicable under the corresponding Parent Option, a
number of shares of Holdco Sub Common Stock identical to the class and number of
shares of Parent Common Stock that were subject to such corresponding Parent
Option (a "HOLDCO SUB OPTION") and (ii) any such Parent Award shall entitle the
holder thereof to receive a payment in cash upon the same terms and conditions
that were applicable under the corresponding Parent Award equal to the fair
market value of the identical number of shares of Holdco Sub Class A Common
Stock as shares of Parent Class A Common Stock.  Parent and Holdco Sub agree to
take all corporate and other action as shall be necessary to effectuate the
foregoing, and Parent shall use its best efforts to obtain, if required, prior
to the Closing Date, such consent of each holder of a Parent Option and Parent
Award as shall be necessary to effectuate the foregoing.  Holdco Sub shall take
all corporate and other action necessary to reserve and make available for

rights thereunder.

approve a stockholders' rights plan having substantially the same terms and
conditions as the Rights Agreement, dated as of November 16, 1995 (the "RIGHTS
AGREEMENT"), between Parent and Norwest Bank Minnesota, N.A., as Rights Agent,
and (b) the Parent Board shall adopt and approve an amendment to the Rights
Agreement which shall cause the Rights (as defined therein) to expire
