HOLDING COMPANY REORGANIZATION
 
    NWA Corp. succeeded Old NWA Corp. in a reorganization effected on November

Newbridge Merger Corporation, a Delaware corporation and at such date a
wholly-owned subsidiary of NWA Corp. ("Merger Sub"), Merger Sub merged (the
"Merger") with and into Old NWA Corp., which was the surviving corporation in
the Merger, and ceased to exist. Pursuant to the Merger,
 
    (i) each share of Common Stock, par value $.01 per share, of Merger Sub
        issued and outstanding prior to the effective time of the Merger (the

         $.01 per share, of NWA Corp.; and
 
   (iii) each share of Series C Preferred Stock, par value $.01 per share of Old
         NWA Corp. issued and outstanding or held in its treasury immediately

Corp.

    As of October 31, 1998, 81,288,206 shares of Common Stock were issued and
outstanding.
 
    Each share of Common Stock is entitled to one vote at all meetings of
stockholders of NWA Corp. for the election of directors (other than directors
elected by holders of the Series C Preferred Stock) and all matters submitted to
stockholder vote.
 
    Holders of the Common Stock participate equally as to any dividends or other
distributions, including dividends payable in shares of Common Stock (or
securities having rights to acquire Common Stock). Upon any liquidation,
dissolution or winding up of NWA Corp., holders of the Common Stock are entitled
to share equally and ratably in the assets of NWA Corp., if any, remaining after
the payment of all debts and liabilities of NWA Corp. and the liquidation
preference of any outstanding Preferred Stock. Holders of Common Stock have no
preemptive, subscription or redemption rights and are not subject to further
calls or assessments. Holders of Common Stock have no right to cumulate their
votes in the election of directors. The outstanding shares of Common Stock are
duly authorized, validly issued, fully paid and nonassessable. The Common Stock
is quoted on the Nasdaq National Market.
 
NWA CORP. PREFERRED STOCK
 
Series C Preferred Stock
 
    As of October 31, 1998, 5,650,633 shares of Series C Preferred Stock were
issued and outstanding.
 
CONVERSION RIGHTS
 
    Each share of Series C Preferred Stock is convertible at any time at the
option of the holder thereof into 1.364 shares of Common Stock.
 
    Each share of Series C Preferred Stock automatically converts into 1.364
shares of the Common Stock upon the sale, transfer, exchange or other
disposition of record or beneficial ownership of such share to (or with) any
person who is not an employee trust or other "Qualified Holder" (a
"Non-Qualified Sale").
 
PUT RIGHT
 
    During the 60-day period ending ten years after August 1, 1993 (the "Put
Date"), the employee trusts and other "Qualified Holders" of the Series C
Preferred Stock (generally consisting of current and former NWA Corp. employees
and their spouses, children and heirs) will have the right to put such stock to
NWA Corp. Prior to the commencement of such 60-day period, NWA Corp. will have
the right to elect either of the following:
 
    (i) to repurchase such Series C Preferred Stock with cash equal to the Put
        Price (defined below) or with shares of Common Stock having an aggregate
        trading value (based on the average
 
                                       6
<PAGE>
        closing prices for Common Stock during the 30-day period ending on the
        Put Date) equal to the Put Price; or
 
    (ii) to permit the relevant trust or Qualified Holder either (A) to receive
         the number of shares of Common Stock into which such Series C Preferred
         Stock would otherwise then be convertible plus the "Excess Amount" (as
         defined below) in cash, or (B) to have such number of shares of Common
         Stock otherwise issuable upon conversion sold by NWA Corp., whereupon
         the relevant trust or Qualified Holder would receive in cash the
         proceeds realized upon such sale plus the Excess Amount.
 
    Notwithstanding the foregoing, any election by NWA Corp. to provide those
exercising put rights with shares of Common Stock in lieu of cash (as described
in clause (i) of the preceding paragraph) would require the approval of a
majority of the Series C Directors (such directors being described under "Voting
Rights" below). Any decision by NWA Corp. not to repurchase any shares of Series
C Preferred Stock as described above requires the consent of a majority of the
Series C Directors.
 
    The "Put Price" in 2003 of the Series C Preferred Stock will be equal to a
pro rata portion of the actual savings resulting from labor cost savings
agreements entered into in 1993 ($266.3 million as of September 30, 1998). The
actual labor cost savings is calculated as the excess of the amount NWA Corp.
would have paid its employees in basic hourly wages during the period covered by
the labor cost savings absent the labor cost savings over the amount actually
paid, together with certain savings in respect of reduced vacation accruals and
certain work rule changes.
 
    The "Excess Amount" for each share of Series C Preferred Stock as to which
the put right is exercised (which Excess Amount may be payable when NWA Corp.
has elected the mechanism described in clause (ii) of the third preceding
paragraph) is equal to the excess of (i) the Put Price over (ii) the specified
market price per share of the Common Stock received pursuant to such clause
(ii), multiplied by the number of shares of Common Stock into which one share of
Series C Preferred Stock may then be converted.
 
    In the event NWA Corp. fails to fulfill its mandatory redemption obligations
as described above, on a quarterly basis thereafter NWA Corp. must use all cash
held by NWA Corp. (or available under revolving credit agreements) in excess of
all the requirements within one year of such determination date ("Available
Cash") to make partial pro rata redemptions, provided such redemptions are not
prohibited under applicable credit agreements. Cash held by NWA Corp.'s
subsidiaries will be included in the calculation of Available Cash only to the
extent such cash is made available to NWA Corp. pursuant to applicable law or
any loan agreements or instruments to which NWA Corp. or any of its subsidiaries
is a party or is subject.
 
DIVIDENDS
 
    The "Dividend Date" for the Series C Preferred Stock is August 1 of each
year. If the Common Stock is listed on the New York or American Stock Exchange
or quoted on the Nasdaq National Market on the business day preceding a Dividend
Date, no dividend will accrue on the Series C Preferred Stock in respect of the
year then ended. If the Common Stock is not so listed or quoted on such business
day, on the following Dividend Date each share of Series C Preferred Stock will
accrue a cumulative dividend for the year then ended equal to 5% of (i) the
actual labor cost savings realized by NWA Corp. from August 1, 1993 to such
Dividend Date plus the aggregate amount of previously accrued dividends on such
Series C Preferred Stock, divided by (ii) the total number of shares of Series C
Preferred Stock issued by NWA Corp. Because the Common Stock is approved for
quotation on the Nasdaq National Market, no dividends have accrued on the Series
C Preferred Stock.
 
    In the event NWA Corp. fails to fulfill its mandatory redemption obligations
described above, as of the Put Date the Series C Preferred Stock will begin to
accrue a cumulative dividend payable quarterly
 
                                       7
<PAGE>
at a rate equal to the greater of 12% per annum or the highest default dividend
rate then payable on any series of Preferred Stock of NWA Corp.
 
VOTING RIGHTS
 
    The Series C Preferred Stock votes with the Common Stock on all matters
submitted to stockholders for a vote, except with respect to the election of
directors. When voting with the Common Stock, each share of Series C Preferred
Stock has a number of votes equal to 1.364.
 
    With respect to the election of directors, the Series C Preferred Stock
voting as a separate class is entitled to elect a slate of three Series C
Directors, one of whom is to be nominated by the International Brotherhood of
Teamsters, Chauffeurs, Warehousemen and Helpers of America ("IBT"), one by the
International Association of Machinists and Aerospace Workers ("IAM") and one by
the Northwest Master Executive Council (the "Northwest MEC") of the Air Line
Pilots Association, International ("ALPA"). Until July 31, 2003, the number of
Series C Directors will be the greater of three or the number that represents at
least 15% of NWA Corp.'s directors.
 
    In the event NWA Corp. fails to fulfill its mandatory redemption obligation
described above, the number of Series C Directors will be increased to the
greater of (i) three more than the number of Series C Directors then serving on
NWA Corp.'s Board, and (ii) the number of directors that would cause the
proportion of Series C Directors to the total number of directors to be equal to
the proportion of the total voting power of all shares of Series C Preferred
Stock then outstanding to the total voting power of all shares of all voting
capital stock of NWA Corp. then outstanding.
 
    If the holders of Series C Preferred Stock are entitled to elect more than
three directors, the Northwest MEC, the IBT and the IAM will each be entitled to
nominate one-third of the Series C Directors, and if the total number of Series
C Directors is not a multiple of three, any remaining Series C Directors will be
nominated by a unanimous vote of the existing Series C Directors designated by
these three unions.
 
    Holders of Series C Preferred Stock are not entitled to vote such stock for
the election of any directors other than the Series C Directors. The entitlement
of the holders of Series C Preferred Stock to elect the Series C Directors will
expire on the first date on which no shares of Series C Preferred Stock are
outstanding, whether as a result of conversions, exchanges, repurchases or
redemptions.
 
OPTIONAL REDEMPTION
 
    NWA Corp. may redeem the Series C Preferred Stock in whole or in part at the
Put Price at any time on 60 days' prior notice. Notwithstanding NWA Corp.'s
right to redeem the Series C Preferred Stock in whole, until August 1, 2003,
each trust may retain one share of Series C Preferred Stock for purposes of
exercising the right to elect Series C Directors, as described above.
 
LIQUIDATION PREFERENCE
 
    The Series C Preferred Stock has a liquidation preference per share equal to
the Put Price. The issuance by NWA Corp. of a new series of Preferred Stock that
ranks, as to both preference in liquidation and bankruptcy and the receipt of
dividends and repayment, senior to or PARI PASSU with the Series C Preferred
Stock, does not require the consent of the holders of the Series C Preferred
Stock.
 
Series D Junior Participating Preferred Stock
 
    On November 20, 1998, the Board of Directors of NWA Corp. authorized and
declared a dividend of one right ("Right") for each outstanding share of Common
Stock. The dividend is payable to the stockholders of record as of the Effective
Time of the Merger (the "Record Date"). Each Right entitles the registered
holder to purchase from NWA Corp. one one-hundredth of a share of Series D
Junior
 
                                       8
<PAGE>
Participating Preferred Stock at a price of $150 per one one-hundredth of a
share of Series D Junior Participating Preferred Stock (as the same may be
adjusted, the "Purchase Price"). The description and terms of the Rights are set
forth in a Rights Agreement dated as of November 20, 1998, as the same may be
amended from time to time (the "Rights Agreement"), between NWA Corp. and
Norwest Bank Minnesota, N.A., as Rights Agent (the "Rights Agent").
 
    Until the earlier to occur of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") have acquired Beneficial Ownership (as such term is defined in the
Rights Agreement) of a number of shares of Common Stock equal to 19% or more
(25% or more in the case of certain Institutional Investors (as such term is
defined in the Rights Agreement)) of the number of the shares of Common Stock
then issued and outstanding; provided, however, that if a person or group would
be deemed an Acquiring Person upon the adoption of the Rights Agreement, such
person or group will not be deemed an "Acquiring Person" for any purposes of the
Rights Agreement unless and until such person or group acquires Beneficial
Ownership of any additional shares of Common Stock after the date of the
adoption of the Rights Agreement unless upon the consummation of the acquisition
of such additional shares of Common Stock such person or group does not
beneficially own a number of shares of Common Stock equal to 19% or more (25% or
more in the case of certain Institutional Investors) of the number of the shares
of Common Stock then issued and outstanding or (ii) 10 business days (or such
later date as may be determined by action of the Board of Directors of NWA Corp.
prior to such time as any person or group of affiliated persons becomes an
Acquiring Person) following the commencement of, or announcement of an intention
to make, a tender offer or exchange offer the consummation of which would result
in the beneficial ownership by a person or group of a number of shares of Common
Stock equal to 19% or more of the number of shares of Common Stock then issued
and outstanding (the earlier of such dates being called the "Distribution
Date"), the Rights will be evidenced, with respect to any of the certificates
for shares of Common Stock outstanding as of the Record Date, by such
certificate together with a copy of the Summary of Rights sent to the holders of
the shares of Common Stock as of the Record Date. The phrase "then outstanding",
when used with reference to a person or group's Beneficial Ownership of shares
of Common Stock, means the number of shares of Common Stock then issued and
outstanding together with the sum of (i) all the shares of Common Stock issuable
upon conversion of all the shares of Series C Preferred Stock issued and
outstanding as of the date of the Rights Agreement, (ii) all the shares of
Common Stock issuable upon the exercise of all employee stock options then
issued and outstanding as of November 16, 1995 and (iii) any other shares of
Common Stock not then actually issued and outstanding but which such person or
group would be deemed to beneficially own thereunder (together, the "outstanding
Common Stock")
 
    The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights), the Rights will be transferred with and
only with the shares of Common Stock. Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Common Stock certificates issued
after the Record Date upon transfer or new issuances of Common Stock (including
pursuant to the conversion of Series C Preferred Stock) will contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier redemption or expiration of the Rights), the surrender for transfer of
any certificates for Common Stock outstanding as of the Record Date, even
without such notation or a copy of the Summary of Rights, will also constitute
the transfer of the Rights associated with the Common Stock represented by such
certificate. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date and such separate Right Certificates alone will evidence the
Rights.
 
    The Rights are not exercisable until the Distribution Date. The Rights will
expire on November 16, 2005 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by NWA Corp., in each case as described below.
 
                                       9
<PAGE>
    The Purchase Price payable, and the number of shares of Series D Junior
Participating Preferred Stock or other securities or property issuable, upon
exercise of the Rights are subject to adjustment from time to time to prevent
dilution (i) in the event of a stock dividend on, or a subdivision, combination
or reclassification of, the Series D Junior Participating Preferred Stock, (ii)
upon the grant to holders of the Series D Junior Participating Preferred Stock
of certain rights or warrants to subscribe for or purchase Series D Junior
Participating Preferred Stock at a price, or securities convertible into Series
D Junior Participating Preferred Stock with a conversion price, less than the
then-current market price of the Series D Junior Participating Preferred Stock
or (iii) upon the distribution to holders of the Series D Junior Participating
Preferred Stock of evidences of indebtedness or assets (excluding regular
periodic cash dividends or dividends payable in Series D Junior Participating
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).
 
    The number of outstanding Rights are also subject to adjustment in the event
of a stock split of the Common Stock or a stock dividend on the Common Stock
payable in Common Stock or subdivisions, consolidations or combinations of the
Common Stock occurring, in any such case, prior to the Distribution Date.
 
    Shares of Series D Junior Participating Preferred Stock purchasable upon
exercise of the Rights will not be redeemable. Each share of Series D Junior
Participating Preferred Stock will be entitled, when, as and if declared, to a
minimum preferential quarterly dividend payment of $1 per share but will be
entitled to an aggregate dividend of 100 times the dividend declared per share
of Common Stock. In the event of liquidation, the holders of the Series D Junior
Participating Preferred Stock will be entitled to a minimum preferential
liquidation payment of $100 per share (plus any accrued but unpaid dividends)
but will be entitled to an aggregate payment of 100 times the payment made per
share of Common Stock. Each share of Series D Junior Participating Preferred
Stock will have 100 votes, voting together with the Common Stock. Finally, in
the event of any merger, consolidation or other transaction in which shares of
Common Stock are converted or exchanged, each share of Series D Junior
Participating Preferred Stock will be entitled to receive 100 times the amount
received per share of Common Stock. These rights are protected by customary
antidilution provisions.
 
    In the event that any person or group of affiliated or associated persons
becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right at the then
current exercise price of the Right, that number of shares of Common Stock (or
one one-hundredths of a share of Series D Junior Participating Preferred Stock)
having a market value of two times the exercise price of the Right.
 
    In the event that, after a person or group has become an Acquiring Person,
NWA Corp. is acquired in a merger or other business combination transaction or
50% or more of its consolidated assets or earning power are sold, proper
provision will be made so that each holder of a Right (other than Rights
beneficially owned by an Acquiring Person which will have become void) will
thereafter have the right to receive, upon the exercise thereof at the then
current exercise price of the Right, that number of shares of common stock of
the person with whom NWA Corp. has engaged in the foregoing transaction (or its
publicly traded parent), which number of shares at the time of such transaction
will have a market value of two times the exercise price of the Right.
 
    At any time after any person or group becomes an Acquiring Person and prior
to the acquisition by such person or group of beneficial ownership of a number
of shares of Common Stock equal to 50% or more of the number of shares of
outstanding Common Stock, the Board of Directors of NWA Corp. may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or one one-hundredth of a share of Series D Junior Participating Preferred Stock
(or of a share of a class or series of NWA
 
                                       10
<PAGE>
Corp.'s preferred stock having equivalent rights, preferences and privileges),
per Right (subject to adjustment).
 
    With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional shares of Series D Junior Participating
Preferred Stock will be issued (other than fractions which are integral
multiples of one one-hundredth of a share of Series D Junior Participating
Preferred Stock, which may, at the election of NWA Corp., be evidenced by
depositary receipts) and in lieu thereof, an adjustment in cash will be made
based on the market price of the Series D Junior Participating Preferred Stock
on the last trading day prior to the date of exercise.
 
    At any time prior to the time an Acquiring Person becomes such, the Board of
Directors of NWA Corp. may redeem the Rights in whole, but not in part, at a
price of $.01 per Right (the "Redemption Price"). Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only right of the holders of Rights will be to receive the Redemption Price.
 
    For so long as the Rights are then redeemable, NWA Corp. may, except with
respect to the Redemption Price, amend the Rights in any manner. After the
Rights are no longer redeemable NWA Corp. may, except with respect to the
Redemption Price, amend the Rights in any manner that does not adversely affect
the interests of holders of the Rights.
 
    Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of NWA Corp., including, without limitation, the right to vote
or to receive dividends.
 
    A copy of the Rights Agreement is available free of charge from NWA Corp.
This summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement, as the same may
be amended from time to time, which is hereby incorporated herein by reference.
 
TRANSFER AGENT AND REGISTRAR
 
    Norwest Bank Minnesota, National Association is the transfer agent and
registrar for the Common Stock.
 
                              PLAN OF DISTRIBUTION
 
    The Selling Stockholders have advised us that they may distribute the
Offered Shares from time to time in one or more transactions (which may involve
block transactions):
 
    (i) on the Nasdaq National Market or such other quotation system or national
        security exchanges on which NWA Corp.'s Common Stock is quoted or
        listed, in transactions that may include special offerings and exchange
        distributions pursuant to and in accordance with the rules of such
        exchanges,
 
    (ii) in the over-the-counter market, or
 
   (iii) in transactions otherwise than on such exchanges or in the
         over-the-counter market, or in a combination of any such transactions.
 
    The Selling Stockholders may effect such transactions at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices or at fixed prices. The Selling Stockholders may
effect such transactions by selling the Offered Shares to or through broker-
dealers and such broker-dealers will receive compensation in the form of
discounts or commissions from the Selling Stockholders and may receive
commissions from the purchasers of the Offered Shares for whom they may act as
agent (which discounts or commissions from the Selling Stockholders or such
purchasers will not exceed those customary in the type of transactions
involved).
 
                                       11
<PAGE>
    Any broker-dealers that participate with the Selling Stockholders in the
distribution of the Offered Shares may be deemed to be "underwriters" within the
meaning of the Securities Act of 1933, as amended (the "Securities Act"), and
any commissions or discounts received by such broker-dealers and any profit on
the resale of the Offered Shares by such broker-dealers might be deemed to be
underwriting discounts and commissions under such act.
 
    Upon our being notified by any Selling Stockholder that any material
arrangement has been entered into with a broker or dealer for the sale of any of
the Offered Shares through a secondary distribution, or a purchase by a broker
or dealer, a supplemented prospectus will be filed, if required, pursuant to
Rule 424(b) under the Securities Act, disclosing the following:
 
    (a) the names of such broker-dealers;
 
    (b) the number of shares involved;
 
    (c) the price at which such shares are being sold;
 
    (d) the commission paid or the discounts or concessions allowed to such
       broker-dealers;
 
    (e) where applicable, that such broker-dealers did not conduct any
       investigation to verify the information set out or incorporated by
       reference in this Prospectus, as supplemented; and
 
    (f) other facts material to the transaction.
 
CERTAIN RESTRICTIONS ON SALES BY THE SELLING STOCKHOLDERS
 
    Under the Investment Agreement, the Selling Stockholders have agreed, among
other things, that until the earlier of (i) the date that is two years after the
Closing Date and (ii) such time as NWA Corp. has failed to ensure that a
designee of 1992 Air, Inc. is elected to the Board of Directors of NWA Corp.
when the right of 1992 Air, Inc. to designate a director to the Board of
Directors of NWA Corp. (A) remains in effect, (B) has been terminated by virtue
of a written instrument executed by 1992 Air, Inc. or its assignee and NWA Corp.
in connection with an order, ruling, decision, judgment, consent decree or other
decree of a court or Governmental Authority (a "Government Order"), or (C) would
violate a Government Order, each of the Selling Stockholders will not, directly
or indirectly, offer, sell, transfer, tender, pledge or encumber, assign or
otherwise dispose of any Offered Shares other than in connection with bona fide
pledges of such Offered Shares to secure bona fide borrowings or in connection
with bona fide hedging transactions executed by registered broker-dealers;
provided, however, that the Selling Stockholders will be permitted to offer,
sell, transfer, tender, pledge or encumber, assign or otherwise dispose of,
during such two-year period, the following:
 
    (i) in the aggregate, such percentage of the aggregate number of Offered
        Shares issued to the Selling Stockholders at the Closing as is equal to
        the percentage of the aggregate shares of Common Stock beneficially
        owned by Alfred Checchi, Gary Wilson and Richard Blum (collectively, the
        "Principals") on the Closing Date that are sold, transferred, assigned
        or otherwise actually disposed of by the Principals in the aggregate
        during such two-year period;
 
    (ii) in the event that the Selling Stockholders acquire Continental Class A
         Common Stock from NWA Corp. pursuant to a right of first offer granted
         in the Investment Agreement ("Reoffered Securities"), in the aggregate,
         such percentage of the aggregate number of Offered Shares as is
         represented by the percentage such Reoffered Securities bears to the
         total number of shares of Continental Class A Common Stock the
         beneficial ownership of which is acquired by NWA Corp. and Old NWA
         Corp. at the Closing; and
 
   (iii) Offered Shares to one or more of its affiliates that is directly or
         indirectly controlled by it.
 
    In addition, under the Standstill Agreement dated as of November 20, 1998
(the "Standstill Agreement"), between NWA Corp. and the persons identified on
the signature pages thereof, the
 
                                       12
<PAGE>
Selling Stockholders have agreed, among other things, that they will not, and
will cause their affiliates not to, directly or indirectly, sell, transfer any
beneficial interest in, pledge, hypothecate or otherwise dispose of any voting
securities of NWA Corp. in any transaction that to the knowledge of such Selling
Stockholder would result in a transfer, pledge, hypothecation or other
disposition to any person or group that would have, upon consummation of such
sale, transfer, pledge, hypothecation or other disposition, directly or
indirectly, beneficial ownership of or the right to acquire beneficial ownership
of such number of NWA Corp. voting securities as represent more than 5% of the
total number of votes which could be cast in an election of members of the NWA
Corp. Board of Directors ("NWA Corp. Combined Voting Power"); PROVIDED, that
each Selling Stockholder will be permitted to sell, transfer or otherwise
dispose of NWA Corp. voting securities:
 
    (a) to one or more of its affiliates that is directly or indirectly
       controlled by it;
 
    (b) to any one or more of the Principals;
 
    (c) to certain institutional investors;
 
    (d) pursuant to a tender or exchange offer for NWA Corp. voting securities
       which is not opposed by the NWA Corp. Board of Directors;
 
    (e) in a merger transaction; or
 
    (f) by testamentary devise;
 
    PROVIDED, that in the case of clauses (a) and (f) the transferee agrees in
writing to be bound by the terms of the Standstill Agreement; PROVIDED, FURTHER,
that no sales, transfers or other dispositions to any person or group pursuant
to clause (c) may occur if to the knowledge of such Selling Stockholder such
person or group would have, upon consummation of such sale, transfer or other
disposition, directly or indirectly, beneficial ownership of or the right to
acquire beneficial ownership of such number of NWA Corp. voting securities as
represent more than 14.9% of the NWA Corp. Combined Voting Power.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 145 of the General Corporation Law of the State of Delaware (the
"Delaware Law") empowers a Delaware corporation to indemnify any persons who
are, or are threatened to be made, parties to any threatened, pending or
completed legal action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of such
corporation), by reason of the fact that such person is or was an officer,
director, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that such officer,
director, employee or agent acted in good faith and in a manner he reasonably
believed to be in or not opposed to the corporation's best interests, and, for
criminal proceedings, had no reasonable cause to believe his conduct was
unlawful. A Delaware corporation may indemnity officers and directors in an
action by or in the right of the corporation under the same conditions, except
that no indemnification is permitted without judicial approval if the officer or
director is adjudged to be liable to the corporation. Where an officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses which
such officer or director actually and reasonably incurred.
 
    In accordance with Section 102(b)(7) of the Delaware Law, the NWA Corp.
Charter provides that the directors of NWA Corp. shall not be personally liable
to NWA Corp. or its stockholders for monetary damages for violations of their
fiduciary duty.
 
    Article VIII of the NWA Corp. Bylaws provides for indemnification of the
officers and directors of NWA Corp. to the fullest extent permitted by
applicable law.

ITEM 17. UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
post effective amendment to this registration statement:
 
    (i) To include any prospectus required by Section 10(a)(3) of the Securities
        Act of 1933, as amended (the "Securities Act");
 
    (ii) To reflect in the prospectus any facts or events arising after the
         effective date of the registration statement (or the most recent
         post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the registration statement. Notwithstanding the foregoing, any
         increase or decrease in the volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high and of the estimated
         maximum offering range may be reflected on the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than 20 percent change in
         the maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective registration statement;
 
   (iii) To include any material information with respect to the plan of
         distribution not previously disclosed in the registration statement or
         any material change to such information in the registration statement;
 
PROVIDED, HOWEVER, that paragraph (1)(i) and (1)(ii) above do not apply if
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act") that are incorporated by reference in the registration
statement.
 
    (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.
 
    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions set forth in response to Item 15, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)

                               -------------------



                  Newbridge Parent Corporation, a corporation organized and
existing under the General Corporation Law of the State of Delaware (hereinafter
called the "Corporation"; it being understood that such term, with respect to
all times prior to the merger of Newbridge Merger Corporation, a Delaware
corporation, with and into Northwest Airlines Corporation, a Delaware
corporation ("Old Northwest"), shall refer to Old Northwest), hereby certifies
that the following resolution was duly adopted by the Board of Directors of the
Corporation as required by Section 151 of the General Corporation Law of the
State of Delaware by written consent in lieu of a meeting on November 20, 1998:

                  RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of the Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the
Corporation's Restated Certificate of Incorporation, as amended to date
(hereinafter called the "Certificate of Incorporation"), the Board of Directors
hereby creates a series of Preferred Stock, par value $.01 per share (the
"Preferred Stock"), of the Corporation and hereby states the designation and
number of shares, and fixes the relative rights, powers and preferences thereof,
and the limitations thereof, as follows:

                  (1) Designation. The designation of the series of Preferred
Stock authorized by this resolution shall be Series C Voting Preferred Stock,
par value $0.01 per share" (the "Series C Voting Preferred Stock"), consisting
of 25,000,000 shares.

                                       1
<PAGE>

                  (2) Rank. The Series C Voting Preferred Stock shall, with
respect to dividend, repurchase, repayment and redemption rights and rights on
any liquidation, winding up or dissolution of the Corporation, rank junior to
the series A preferred stock, par value $0.01 per share (the "Series A Preferred
Stock") of the Corporation and the series B preferred stock, par value $0.01 per
share (the "Series B Preferred Stock"), of the Corporation. The Series C Voting
Preferred Stock shall, with respect to dividend, repurchase, repayment and
redemption rights and rights on any liquidation, winding up or dissolution of
the Corporation, rank prior to all classes of the common stock, par value $0.01
per share, of the Corporation. All equity securities of the Corporation to which
the Series C Voting Preferred Stock may rank prior with respect to dividends and
upon liquidation, dissolution, winding up or otherwise are collectively referred
to herein as the "Junior Securities"; all equity securities of the Corporation
as to which the Series C Voting Preferred Stock may rank on a parity as to any
one of dividends or upon liquidation, dissolution, winding up or otherwise and
does not rank senior as to any of the same are collectively referred to herein
as the "Parity Securities"; and all equity securities of the Corporation to
which the Series C Voting Preferred Stock may rank junior, whether with respect
to dividends or upon liquidation, dissolution, winding up or otherwise, are
collectively referred to herein as the "Senior Securities". The Series C Voting
Preferred Stock shall be subject to the creation of Junior Securities, Parity
Securities and Senior Securities.

                  (3) Dividends. (i) The holders of the shares of Series C
Voting Preferred Stock shall be entitled to receive, when, as and if declared by
the Board of Directors, out of funds legally available for the payment of
dividends, cumulative dividends at the annual rate described in paragraph
(3)(ii) (the "Dividend Rate"). Such dividends shall accrue annually in arrears.
The first dividend shall accrue on August 1, 1994 (unless the Common Stock, par
value $.01 per share, of the Corporation (the "Common Stock") is Publicly Traded
prior to August 1, 1994, in which event no dividend shall accrue) and
thereafter, dividends shall accrue on each August 1 (each date on which
dividends are scheduled to accrue being a "Dividend Date"); provided, however,
that if the Common Stock becomes Publicly Traded during the twelve-month period
from one Dividend Date to the next Dividend Date (each such period, a "Dividend
Year"), then no dividend shall accrue for such Dividend Year or any Dividend
Year thereafter, provided, further, that if thereafter during such Dividend Year
or during any succeeding Dividend Year, the Common Stock should not be Publicly
Traded on the business day immediately preceding the Dividend Date for such
Dividend Year, the dividend shall commence accruing in full once again, in the
manner described herein, commencing on the Dividend Date occurring at the end of
such Dividend Year. Such dividends shall accrue to those parties who hold the
Series C Voting Preferred Stock of record, or who are deemed pursuant to Section
2.2 of the Letter Agreements to hold such Series C Voting Preferred Stock, at
the close of business on the fifteenth day of the month immediately preceding
each Dividend Date (each of such dates being a "Record Date"). Each of such
annual dividends shall be fully cumulative and shall accrue (whether or not
declared), without interest, from the first day of the twelve-month period at
the end of which such dividend may be accrued as herein provided.

                  (ii) (a) The Dividend Rate per share of Series C Voting
Preferred Stock shall be 5% per annum of (i) the aggregate Actual Savings
realized by the Corporation for all holders of Series C Voting Preferred Stock
from the Wage Savings Date to the Dividend Date, increased by the aggregate
amount of the previously accrued dividends, divided by (ii) the total number of
shares of Series C Voting Preferred Stock issued (or deemed, pursuant to Section
2.2



                                       2
<PAGE>


of the Letter Agreements, to have been issued by the Corporation), without
taking into account any exercise of the Special Conversion Option; provided,
however, that dividends shall cease to accrue with respect to any share of the
Series C Voting Preferred Stock upon either the conversion or repurchase of such
share.

                  (b) In the event that the Corporation fails to take such
action with respect to all of the Series C Voting Preferred Stock with respect
to which the Put Right is exercisable pursuant to the terms of paragraphs 9(i)
or 9 (iii) upon exercise of such Put Right, effective as of the Put Date each
outstanding share of Series C Voting Preferred Stock shall start to accrue a
quarterly dividend at a rate equal to the greater of (x) 12% per annum or (y)
the highest dividend rate payable on any then outstanding series or class of the
Corporation's preferred stock in the event of a default by the Corporation in
the redemption or payment of dividends on such series or class of preferred
stock, in each case of the amount per share specified in Section 3 (ii)(a)
above, until such shares are repurchased in accordance with paragraphs 9(i) or 9
(iii).

                    (iii) All dividends accrued with respect to shares of the
Series C Voting Preferred Stock pursuant to paragraph (3)(i) shall accrue pro
rata to the holders entitled thereto.

                     (iv) Subject to the foregoing provisions of this paragraph
(3) and the provisions of paragraph 9(iv), the Board of Directors may declare,
and the Corporation may pay or set apart for payment, dividends and other
distributions on any of the Junior Securities or Parity Securities, and may
repurchase or otherwise redeem any of the Junior Securities or Parity Securities
or any warrants, rights, options or other securities exercisable for or
convertible into any of the Junior Securities or Parity Securities, and the
holders of the shares of the Series C Voting Preferred Stock shall not be
entitled to share therein.

                  (4) Liquidation Preference. (i) In the event of any voluntary
or involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, the holders of shares of Series C Voting Preferred Stock then
outstanding shall be entitled to be paid out of the assets of the Corporation
available for distribution to its stockholders an amount in cash equal to the
Put Price for each such share outstanding on the date of liquidation,
dissolution or winding up before any payment shall be made or any assets
distributed to the holders of any of the Junior Securities.

                  Except as provided in the preceding sentence, holders of
Series C Voting Preferred Stock shall not be entitled to any distribution in the
event of liquidation, dissolution or winding up of the affairs of the
Corporation. If the assets of the Corporation are not sufficient to pay in full
the liquidation payments payable to the holders of outstanding shares of the
Series C Voting Preferred Stock and any Parity Securities, after payment in full
of any liquidation preference on any Senior Securities, then the holders of all
such shares shall share ratably in such distribution of assets in accordance
with the amount which would be payable on such distribution if the amounts to
which the holders of outstanding shares of Series C Voting Preferred Stock and
the holders of outstanding shares of such Parity Securities are entitled were
paid in full.

                  (ii) For the purposes of this paragraph 4, neither the
voluntary sale, conveyance, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all the property or
assets of the Corporation nor the consolidation or merger of the Corporation
with one or more other corporations shall be deemed to be a voluntary or


                                       3
<PAGE>



involuntary liquidation, dissolution or winding up; provided, however, in the
event that the Corporation or Northwest Airlines, Inc. ("Northwest") is sold as
an entirety (whether pursuant to a sale of stock, merger, asset sale or
otherwise) prior to the end of the Wage Savings Period, either (a) the issuance
of any Series C Voting Preferred Stock which is required to be issued in the
future by the Corporation pursuant to the Letter Agreements in respect of the
remainder of the Wage Savings Period but which has not yet been so issued
("Unissued Series C Voting Preferred Stock"), and the issuance of any common
stock of the Corporation which is required to be issued in lieu of Unissued
Series C Voting Preferred Stock following the exercise of the Special Conversion
Option, shall be accelerated to the time of such sale or to a time prior to such
sale sufficient to ensure the holders of such stock shall be entitled to
participate in such transaction or (b) other arrangements reasonably acceptable
to the Unions shall be made so that the holders of the Series C Voting Preferred
Stock or persons entitled to receive such common stock shall receive the value
of such shares of Series C Voting Preferred Stock or common stock (as the case
may be) as if such shares had been fully issued at the time of such sale.

                  (5) Optional Redemption. (i) Notwithstanding Section 3.1(d) of
the Letter Agreements, and subject to Sections 2, 6(iv) and 6(v) hereof, the
Corporation may redeem at its option the Series C Voting Preferred Stock, at any
time and from time to time following August 1, 1996, in whole or in part, at a
redemption price equal to the Put Price per share without interest, to the
extent the Corporation shall have funds legally available for such payment;
provided, however, that the Corporation shall not redeem any shares of Series C
Preferred Stock prior to the redemption in full of the Series A Preferred Stock
and Series B Preferred Stock.

                     (ii) Shares of Series C Voting Preferred Stock which have
been issued and reacquired in any manner, including shares purchased or redeemed
or exchanged, shall (upon compliance with any applicable provisions of the laws
of the State of Delaware) have the status of authorized and unissued shares of
Preferred Stock undesignated as to series and may be redesignated and reissued
as part of any series of the Preferred Stock.

                  (6) Procedure for Redemption. (i) In the event the Corporation
shall redeem shares of Series C Voting Preferred Stock, written notice of such
redemption shall be given by first class mail, postage prepaid, mailed not less
than 60 days prior to the redemption date, to each holder of record of the
shares to be redeemed at such holder's address as the same appears on the stock
register of the Corporation; provided, however, that no failure to give such
notice nor any defect thereon shall affect the validity of the proceeding for
the redemption of any shares of Series C Voting Preferred Stock to be redeemed
except as to any holder to whom the Corporation has failed to give said notice
and any holder whose notice was defective. Each such notice shall state: (v) the
redemption date; (w) the number of shares of Series C Voting Preferred Stock to
be redeemed and, if less than all the shares held by such holder are to be
redeemed from such holder pursuant to paragraph 5(i), the number of shares to be
redeemed or exchanged from such holder; (x) the redemption price; (y) the place
or places where certificates for such shares are to be surrendered for payment
of the redemption price; and (z) that dividends on the shares to be redeemed
shall cease to accrue on such redemption date.

                  (ii) Notice having been mailed as aforesaid, from and after
the redemption date (unless default shall be made by the Corporation in
providing money for the payment of the redemption price of the shares called for
redemption) dividends on the shares of Series C Voting


                                       4
<PAGE>



Preferred Stock so called for redemption shall cease to accrue and said shares
shall no longer be deemed to be outstanding and shall have the status of
authorized but unissued shares of Preferred Stock, unclassified as to series,
and shall not be reissued as shares of Series C Voting Preferred Stock, and all
rights of the holders thereof as stockholders of the Corporation (except the
right to receive from the Corporation the redemption price and the rights
provided in paragraph 6 (iii)) shall cease. Upon surrender in accordance with
said notice of the certificates for any shares so redeemed (properly endorsed or
assigned for transfer, if the Board of Directors of the Corporation shall so
require and the notice shall so state), such shares shall be redeemed by the
Corporation at the redemption price aforesaid. In case fewer than all the shares
represented by any such certificate are redeemed or exchanged, a new certificate
shall be issued representing the unredeemed shares without cost to the holder
thereof.

                    (iii) Holders of Series C Voting Preferred Stock to be
redeemed shall be permitted to convert such shares of Series C Voting Preferred
Stock in accordance with the terms set forth in Section 8 hereof during the
60-day notice period.

                     (iv) In the event that fewer than all the outstanding
shares of Series C Voting Preferred Stock are to be redeemed pursuant to
paragraph 5(i), the number of shares to be redeemed shall be determined by the
Board of Directors, and the shares shall be redeemed pro rata among the holders
thereof, including the Trusts and Separate Arrangements (as each such term is
defined in paragraph (4)(iv)), and, within each Trust or Separate Arrangement,
shall be redeemed among the employees who are the beneficiaries of such Trust or
Separate Arrangement in accordance with the terms of such Trust or Separate
Arrangement.

                      (v) Notwithstanding any other provision of this Section
(6), each trust and separate arrangement to which Series C Voting Preferred
Stock was issued pursuant to the Letter Agreements for the benefit of members of
the Unions or management employees (the "Trusts" and "Separate Arrangements")
may retain, for purposes of exercising the corporate governance rights provided
herein and in the By-laws of the Corporation, at least one share of Series C
Voting Preferred Stock, which shall not be subject to optional redemption
pursuant to paragraph 5 prior to the earlier of (x) August 1, 2003 and (y) the
date on which the number of outstanding shares of Employee Stock constitutes
less than 25% of the shares of Employee Stock outstanding on August 1, 1996;
provided, however, that a minimum number of shares shall be retained by such
Trusts and Separate Arrangements so that the proportion of voting rights held by
such Trusts and Separate Arrangements in respect of the Series C Voting
Preferred Stock immediately prior to any optional redemption shall be maintained
subsequent to any optional redemption.

                  (7) Voting Rights. (i) The Series C Voting Preferred Stock
shall be entitled to vote in parity with all voting common stock of the
Corporation on all matters submitted to stockholders for vote, except as set
forth below with respect to the election of directors. The per share vote of
each share of Series C Voting Preferred Stock at any time shall be equal to (a)
(1) the total number of shares of Series C Voting Preferred Stock issued or to
be issued pursuant to the Letter Agreements either to the Trusts or pursuant to
any Separate Arrangements (assuming no exercise of the Special Conversion
Option) or, if greater, the number of shares of Common Stock into which all such
shares of Series C Voting Preferred Stock (including any shares of Series C
Voting Preferred Stock (x) not yet issued, (y) already converted or (z) with
respect to which the Special Conversion Option has been exercised) would be
convertible at such time

                                       5
<PAGE>



hereunder, minus (2) the total number of shares of Series C Voting Preferred
Stock which, prior to such time, have been converted into shares of common
stock, or, if greater, the number of shares of Common Stock into which those
shares would be convertible at such time if they had not previously been
converted, divided by (b) the total number of shares of Series C Voting
Preferred Stock then outstanding.

                  (ii) (a) So long as any shares of the Series C Voting
Preferred Stock are outstanding, the Series C Voting Preferred Stock shall be
entitled to elect three directors, each of whom shall be an individual who is at
that time of his election an eligible candidate by virtue of satisfying the
qualifications described in paragraph 7(ii)(b) below and who thereafter
continues to satisfy such qualifications; shall be elected exclusively by the
holders of the Series C Voting Preferred Stock as set forth in paragraph 7 (ii)
(c) below. Prior to August 1, 1996, the number of Series C Directors shall
constitute not less than 20% of the number of directors sitting on the Board of
Directors. After August 1, 1996 the number of Series C Directors shall be the
greater of (i) three or (ii) 15% of the total number of directors then setting
on the Board of Directors. Subject to the foregoing provisions, the Corporation
may increase the size of the Board of Directors at any time. Holders of Series C
Voting Preferred Stock shall not be entitled to vote such stock for the election
of any directors of the Corporation other than the Series C Directors.

                  (b) Of the three directors that the holders of Series C Voting
Preferred Stock shall be entitled to elect, one shall be qualified to serve as a
Series C Director by virtue of being nominated by the President of the IBT, one
by virtue of being nominated by the President of the IAM and one by virtue of
being nominated by the Northwest Airlines, Inc. Master Executive Council of
ALPA. If the holders of Series C Voting Preferred Stock are entitled under the
terms hereof to elect more than three directors, ALPA, the IBT, and the IAM,
each acting through its President or the Northwest Airlines, Inc. Master
Executive Council of ALPA, shall each be entitled to nominate one-third of the
Series C Directors and if the total number of Series C Directors is not a
multiple of three, any remaining Series C Directors shall be nominated by a
unanimous vote of the existing Series C Directors designated by the three
unions. Only those individuals who are nominated in accordance with this
paragraph 7(ii)(b) shall be qualified to serve as Series C Directors.

                  (c) The holders of Series C Voting Preferred Stock shall be
entitled to vote on the slate of Series C Directors nominated in accordance with
the provisions set forth herein or, to the extent not inconsistent with the
provisions herein, in the bylaws of the Corporation, and shall not have the
right to vote on the election of any single Series C Director individually.

                  (d) In the event that the Corporation fails to repurchase all
of the Series C Voting Preferred Stock with respect to which the Put Right is
exercisable pursuant to paragraphs 9(i) or 9 (iii), effective as of the Put
Date, the number of Series C Directors shall be increased to the greater of (x)
three more than the number of Series C Directors then serving on the
Corporation's Board of Directors or (y) the number of directors that would cause
the proportion of Series C Directors to the total number of directors to be
equal to the proportion of the total voting power of all shares of Series C
Voting Preferred Stock then outstanding to the total voting power of all shares
of all voting capital stock of the Corporation then outstanding.


                                       6
<PAGE>



                    (iii) The entitlement of the Series C Voting Preferred Stock
to elect the Series C Directors shall expire on the first date on which no
shares of Series C Voting Preferred Stock are outstanding, whether as a result
of conversions, exchanges, repurchases or redemptions.

                  (8) Conversion Rights. (i) The Series C Voting Preferred Stock
shall be convertible at any time into common stock of the Corporation on the
basis set forth below. Except to the extent otherwise provided in this paragraph
8, each share of Series C Voting Preferred Stock shall be convertible into 1.364
shares of Common Stock.

                  (ii) On or before the earlier of (a) April 30, 1994 (or, if
later, 30 days after the audited consolidated financial statements of the
Corporation for the fiscal year ended December 31, 1993 have been made available
to the Unions) or (b) 10 days after the filing with the Securities and Exchange
Commission of a registration statement relating to an underwritten initial
public offering of the Common Stock representing not less than 10% of the Common
Stock outstanding on a fully diluted basis after giving effect to such offering,
each of (x) the Trustees of the Trusts and Separate Arrangements, (except for
those Trusts and Separate Arrangements for the benefit of ALPA employees who are
members of the Air Line Pilots Association International ("ALPA"), or the trust
beneficiaries to the extent specified below); and (y) ALPA with respect to the
Trusts and Separate Arrangements for the benefit of ALPA employees, shall have
the right (A) to convert each share of Series C Voting Preferred Stock held by
such Trust or Separate Arrangement into 1.909 shares of Common Stock and (B) to
receive, in respect of all future contributions to such Trust or Separate
Arrangement, Common Stock in lieu of Series C Voting Preferred Stock, at the
same conversion rate specified in clause (A) above; provided, however, that such
right may be exercised with respect to some or all of the shares of Series C
Voting Preferred Stock held or to be received by such Trust or Separate
Arrangement but may be exercised not more than once. The right set forth in this
paragraph 8(ii) is referred to herein as the "Special Conversion Option." The
Special Conversion Option may be exercised by the trust beneficiaries with
respect to stock allocated to their accounts only if the Corporation has
previously filed a registration statement with the Securities and Exchange
Commission with respect to the Common Stock to be received upon exercise of such
option.

                  (iii) [DELETED]

                  (iv)  [DELETED]

                  (v) Each share of Series C Voting Preferred Stock shall
automatically convert into 1.364 shares of the Common Stock upon the sale,
transfer, exchange or other disposition of record or beneficial ownership of
such share to (or with) any person who is not a Qualified Holder (a
"Non-Qualified Sale").

                  (vi) The shares of Series C Voting Preferred Stock shall be
convertible at the main office of the Corporation, and at such other office or
offices, if any, as the Board of Directors may designate, into fully paid and
non-assessable shares (calculated as to each conversion to the nearest
one-hundredth of a share) of Common Stock, at the Conversion Ratio in effect at
the time of conversion set forth above. As used herein, "Conversion Ratio" shall
mean a fraction of which the numerator shall be one and the denominator shall be
the number of shares

                                       7
<PAGE>



of Common Stock into which each share of Series C Voting Preferred Stock is
convertible as provided herein. The Conversion Ratio shall be subject to
adjustment from time to time as set forth below. In order to convert shares of
Series C Voting Preferred Stock into Common Stock the holder thereof shall
surrender at any office hereinabove mentioned the certificate or certificates
therefor, duly endorsed or assigned to the Corporation or in blank, and give
written notice to the Corporation at such office that he or she elects to
convert such shares. No payment or adjustment shall be made upon any conversion
on account of any dividends accrued on the shares of Series C Voting Preferred
Stock surrendered for conversion or on account of any dividends on the Common
Stock issued upon conversion.

                  (vii) Shares of Series C Voting Preferred Stock shall be
deemed to have been converted immediately prior to the close of business on the
day of the surrender of such shares for conversion in accordance with the
foregoing provisions, and the person or persons entitled to receive the Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such Common Stock at such time. As promptly as
practicable on or after the conversion date, the Corporation shall issue and
shall deliver at such office a certificate or certificates for the number of
full shares of Common Stock issuable upon such conversion, together with payment
at the Trading Price in lieu of any fraction of a share, as hereinafter
provided, to the person or persons entitled to receive the same.

                  (viii) In case at any time after the issuance of the Series C
Voting Preferred Stock, the Corporation shall pay or make a dividend or other
distribution on any class of capital stock of the Corporation in shares of its
Common Stock, the Conversion Ratio in effect at the opening of business on the
day following the date fixed for the determination of shareholders entitled to
receive such dividend or other distribution shall be adjusted so that the same
shall equal the ratio determined by multiplying such Conversion Ratio by a
fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
and the denominator shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, such
reduction to become effective immediately after the opening of business on the
day following the date fixed for such determination. For the purposes of this
paragraph 8(viii), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Corporation but shall
include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock. The Corporation shall not pay any dividend
or make any distribution on shares of Common Stock held in the treasury of the
Corporation.

                  (ix) In case at any time after the issuance of the Series C
Voting Preferred Stock, the Corporation shall issue rights or warrants (other
than those referred to in paragraph 8(xii) or stock options granted to
Corporation Employees) to all holders of its Common Stock entitling them to
subscribe for or purchase shares of Common Stock at a price per share less than
the Trading Price per share of the Common Stock on the date fixed for the
determination of shareholders entitled to receive such rights or warrants, the
Conversion Ratio in effect at the opening of business on the day following the
date fixed for such determination shall be adjusted so that the same shall equal
the ratio determined by multiplying such Conversion Ratio by a fraction of which
the numerator shall be the number of shares of Common Stock outstanding at the
close of business on the date fixed for such determination plus the number of
shares of Common Stock which the aggregate of the offering price of the total
number of shares of


                                       8
<PAGE>



Common Stock so offered for subscription or purchase would purchase at such
Trading Price and the denominator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
plus the number of shares of Common Stock so offered for subscription or
purchase, such reduction to become effective immediately after the opening of
business on the day following the date fixed for such determination. For the
purposes of this paragraph 8(ix), the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the
Corporation but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Corporation shall not
issue any rights or warrants in respect of shares of Common Stock held in the
treasury of the Corporation.

                  (x) In case at any time after the issuance of the Series C
Voting Preferred Stock, outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the Conversion Ratio in effect
at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately reduced, and, conversely,
in case at any time after the issuance of the Series C Voting Preferred Stock,
outstanding shares of Common Stock shall each be combined into a smaller number
of shares of Common Stock, the Conversion Ratio in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately increased, such increase or reduction, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

                  (xi) In case at any time after the issuance of the Series C
Voting Preferred Stock, the Corporation shall, by dividend or otherwise,
distribute to all holders of its Common Stock (a) any rights or warrants to
subscribe for or purchase any security of the Corporation (other than those
referred to in paragraphs 8(ix) and 8(xii) or stock options granted to
Corporation Employees) or any evidence of indebtedness or other securities of
the Corporation (other than Common Stock), or (b) cash or other assets (other
than any regular quarterly dividend payable solely in cash out of retained
earnings of the Corporation that may from time to time be fixed by the Board of
Directors of the Corporation), having a fair market value (as determined in a
resolution adopted by the Board of Directors, which shall be conclusive evidence
of such fair market value) in an amount during any 12-month period equal to 10%
or more of an amount determined by multiplying the number of shares of Common
Stock outstanding on the record date for the determination of holders of Common
Stock entitled to receive such distribution, by the Trading Price per share of
the Common Stock on such record date, then in each such case the Conversion
Ratio shall be adjusted so that the same shall equal the ratio determined by
multiplying the Conversion Ratio in effect immediately prior to the close of
business on the date fixed for the determination of shareholders entitled to
receive such distribution by a fraction of which the numerator shall be the
Trading Price per share of the Common Stock on the date fixed for such
determination less the then fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a
resolution) of the portion of the assets or evidences of indebtedness so
distributed applicable to one share of Common Stock and the denominator shall be
such Trading Price per share of the Common Stock, such adjustment to become
effective immediately prior to the opening of business on the day following the
date fixed for the determination of shareholders entitled to receive such
distribution.


                                       9
<PAGE>



                    (xii) (a) In case the Corporation shall, at any time after
the issuance of the Series C Voting Preferred Stock, distribute rights or
warrants, other than rights or warrants to purchase Common Stock at a price per
share equal to or greater than the Trading Price of the Common Stock on the day
next preceding the Trigger Date (as defined below) in respect thereof which are
not exercisable until the occurrence of such Trigger Date, pro rata to all
holders of Common Stock ("Rights") and the date triggering the exercisability of
such Rights (the "Trigger Date") shall have occurred, thus permitting the
holders of such Rights irrevocably to exercise any exchange, subscription or
purchase rights conferred by such Rights, the Conversion Ratio in effect at the
opening of business on the Trigger Date shall be adjusted so that the same shall
equal the ratio determined by multiplying the Conversion Ratio in effect
immediately prior to the close of business on the day prior to the Trigger Date
by a fraction of which the numerator shall be the Trading Price per share of the
Common Stock on the day prior to the Trigger Date less the fair market value of
the Rights so distributed applicable to one share of Common Stock on the Trigger
Date (as determined by the Board of Directors, whose determination shall be
conclusive and described in a resolution) and the denominator shall be such
current Trading Price per share of the Common Stock.

                  (b) Prior to any Trigger Date, the holder of shares of Series
C Voting Preferred Stock shall be entitled to receive upon conversion of such
shares, in addition to the shares of Common Stock issuable upon conversion of
such shares of Series C Voting Preferred Stock (the "Conversion Shares"), the
maximum number of the relevant Rights that any holder of a number of shares of
Common Stock equal to the number of Conversion Shares owns or is entitled to
receive at the time of such conversion in accordance with the terms of and
provisions applicable to such Rights.

                  (c) Notwithstanding the foregoing, in the event that the
Corporation shall distribute Rights pro rata to all holders of Common Stock, the
Corporation may, in lieu of making any adjustment pursuant to this Section, make
proper provision so that each holder of shares of Series C Voting Preferred
Stock who converts such shares (or any portion thereof) after the date fixed for
the determination of shareholders entitled to receive such Rights and prior to
the redemption, expiration, or other termination of the Rights shall be entitled
to receive upon such conversion, in addition to the Conversion Shares, a number
of Rights to be determined as follows: (1) if such conversion occurs on or prior
to the relevant Trigger Date for such Rights, the maximum number of Rights to
which any holder of a number of shares of Common Stock equal to the number of
Conversion Shares has received or is entitled to receive at the time of such
conversion in accordance with the terms and provisions of and applicable to such
Rights; and (2) if such conversion occurs after such Trigger Date, the maximum
number of Rights to which any holder of the number of shares of Common Stock
into which the shares of Series C Voting Preferred Stock so converted were
convertible immediately prior to such Trigger Date would have been entitled on
such Trigger Date in accordance with the terms and provisions of and applicable
to the Rights.

                  (xiii) The reclassification of Common Stock into securities
including other than Common Stock (other than any reclassification upon a
consolidation or merger) shall be deemed to involve (a) a distribution of such
securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the date fixed
for the determination of stockholders entitled to receive such distribution" and
"the date

                                       10
<PAGE>



fixed for such determination" within the meaning of paragraph 8(xi)), and (b) a
subdivision or combination, as the case may be, of the number of shares of
Common Stock outstanding immediately prior to such reclassification into the
number of shares of Common Stock outstanding immediately thereafter (and the
effective date of such reclassification shall be deemed to be "the day upon
which such subdivision becomes effective" or "the day upon which such
combination becomes effective", as the case may be, and "the day upon which such
subdivision or combination becomes effective" within the meaning of paragraph
8(x)).

                  (xiv) The Corporation may make such adjustments in the
Conversion Ratio, in addition to those required by paragraphs 8 (viii), 8(ix),
8(x), 8(xi), 8(xii) and 8(xiii), as it considers to be advisable in order that
any event treated for United States federal income tax purposes as a dividend of
stock or stock rights shall not be taxable to the holders of Common Stock.

                  (xv) No adjustment in the Conversion Ratio shall be required
unless such adjustment would require an increase or decrease of at least one
percent in such ratio; provided, however, that any adjustments which by reason
of this paragraph 8(xv) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
paragraph 8 shall be made to the nearest one-hundredth of a share.

                  (xvi) Whenever the Conversion Ratio is adjusted as herein
provided, the Corporation shall compute the adjusted Conversion Ratio in
accordance with this paragraph 8 and shall prepare a notice stating that the
Conversion Ratio has been adjusted and setting forth the adjusted Conversion
Ratio that shall forthwith be required, and such notice shall be provided by the
Corporation to all holders of Series C Voting Preferred Stock.

                  (xvii) The Corporation shall at all times reserve and keep
available, free from preemptive rights, out of its authorized but unissued
Common Stock, for the purpose of effecting the conversion of shares of Series C
Voting Preferred Stock, the full number of shares of Common Stock then
deliverable upon the conversion of all shares of Series C Voting Preferred Stock
then outstanding.

                  (xviii) The Corporation shall pay any and all taxes that may
be payable in respect of the issue or delivery of shares of Common Stock on
conversion of shares of the Series C Voting Preferred Stock; provided, however,
that the Corporation shall not pay any state or federal income taxes owed by any
holder of the Series C Voting Preferred Stock. In addition, the Corporation
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that in which the shares of Series C Voting Preferred Stock so
converted were registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Corporation the
amount of any such tax, or has established to the satisfaction of the
Corporation that such tax has been paid.

                  (9) Put Right. (i) During the 60-day period ending on the Put
Date, each Qualified Holder, including Trusts and Separate Arrangements for the
benefit of employees of the Unions and members of management, of Series C Voting
Preferred Stock shall have the right to put such holder's Series C Voting
Preferred Stock to the Corporation, in which event the

                                       11
<PAGE>



Corporation shall be required to elect (the "Put Election") either (a) to
repurchase for either cash equal to the Put Price or shares of Common Stock
having a Trading Price per share on the Put Date equal to the Put Price, each of
such holder's shares of Series C Voting Preferred Stock at the Put Price, or (b)
to permit each such holder to elect either (x) to receive the number of shares
of Common Stock into which such holder's shares of Series C Voting Preferred
Stock are convertible, plus the Excess Amount multiplied by the number of such
holder's shares of Series C Voting Preferred Stock which are so converted, or
(y) to have a number of shares of Common Stock equal to the number of shares of
Common Stock into which such holder's shares of Series C Voting Preferred Stock
are convertible sold on such holder's behalf by the Sales Agent or pursuant to
an underwritten public offering and to receive a cash amount equal to (1) the
Offering Price per share of Common Stock sold plus (2) the Excess Amount
multiplied by the number of such holder's shares of Series C Voting Preferred
Stock which have been so converted.

                  (ii) The Corporation shall be required to make the Put
Election on or before the sixtieth day prior to the Put Date, to issue a public
announcement of its election no later than the sixtieth day prior to the Put
Date and, if it has made the election set forth in paragraph 9(i)(b), to deliver
promptly to the holders of Series C Voting Preferred Stock an election form for
such holders to make either the election set forth in paragraph 9(i)(b)(x) or
the election set forth in paragraph 9(i)(b)(y) with respect to their shares of
Series C Voting Preferred Stock, which such election may be made with respect to
all or a portion of the Series C Voting Preferred Stock held by such holder.
Such election form shall be returnable to the Trustees by the Put Date.

                  (iii) Payment by the Corporation to the holders of Series C
Voting Preferred Stock of any cash due to them in respect of their exercise of
the Put Right shall be made on the Put Payment Date. If the Corporation elects
to issue new shares of Common Stock to such holders pursuant to paragraph
9(i)(a), promptly following such election, but not later than the Put Date, the
Corporation shall commence efforts to register such new shares under the
Securities Act of 1933 (the "1933 Act") and shall use its best efforts to cause
such registration to become effective as soon as practicable thereafter.
Delivery of such shares to the holders of Series C Voting Preferred Stock shall
be made seven days after the effective date of such registration or, if later
and the Common Stock is not then Publicly Traded, seven days after delivery to
the Corporation of the investment banker's valuation of the Common Stock in
accordance with the Letter Agreement. Shares of Series C Voting Preferred Stock
with respect to which the Put Right is exercised shall cease to be outstanding
for any purpose and shall be retired upon satisfaction of such Put Right.

                  (iv) If on the Put Date, the Board of Directors of the
Corporation decides not to repurchase all of the Series C Voting Preferred Stock
with respect to which the Put Right has been exercised either (A) for cash or
for shares of Common Stock pursuant to paragraph 9(i)(a), or (b) pursuant to the
procedures set forth in paragraph 9(i)(b), then on such date and at the end of
each succeeding calendar quarter until all of such Series C Voting Preferred
Stock shall have been repurchased (collectively, "Partial Repurchase Dates"),
the Board of Directors of the Corporation shall use all Available Cash on each
such date to repurchase a portion of the Series C Voting Preferred Stock
entirely for cash (a "Partial Repurchase") in accordance with paragraph 9(i)(a),
but only if and to the extent that the Corporation is not prohibited from making
such repurchase under Delaware law or any loan agreement or other instrument to
which it is a party

                                       12

or is subject. Any such partial repurchase shall be made pro rata from among
each holder of Series C Voting Preferred Stock (including the Trusts and
Separate Arrangements) and within each Trust and Separate Arrangement shall be
made among the employees who are beneficiaries of such Trust or Separate
Arrangement in accordance with the terms of such Trust or Separate Arrangement.

                  (v) The right of a Qualified Holder to put shares of Series C
Voting Preferred to the Corporation as specified herein (the "Put Right") may
only be exercised by a holder of Series C Voting Preferred Stock. The Put Right
shall therefore expire as to any shares of Series C Voting Preferred Stock upon
their conversion into shares of Common Stock prior to exercise of the Put Right.

                          NEWBRIDGE PARENT CORPORATION

             (which shall be renamed Northwest Airlines Corporation)

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)

                               -------------------



                  Newbridge Parent Corporation, a corporation organized and
existing under the General Corporation Law of the State of Delaware (hereinafter
called the "Company"), hereby certifies that the following resolution was duly
adopted by the Board of Directors of the Company as required by Section 151 of
the General Corporation Law of the State of Delaware by written consent in lieu
of a meeting on November 20, 1998:

                  RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of the Company (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Company's
Certificate of Incorporation, as amended to date (hereinafter called the
"Certificate of Incorporation"), the Board of Directors hereby creates a series
of Preferred Stock, par value $.01 per share (the "Preferred Stock"), of the
Company and hereby states the designation and number of shares, and fixes the
relative rights, powers and preferences thereof, and the limitations thereof, as
follows:

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series D Junior Participating Preferred Stock" (the
"Series D Preferred Stock") and the number of shares constituting the Series D
Preferred Stock shall be 3,000,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series D Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Company
convertible into Series D Preferred Stock.

                  Section 2.  Dividends and Distributions.

                  (A) Subject to the rights of the holders of any shares of any
series of Preferred Stock of the Company (the "Preferred Stock") (or any similar
stock) ranking prior and superior to the Series D Preferred Stock with respect
to dividends, the holders of shares of Series D



<PAGE>



Preferred Stock, in preference to the holders of Common Stock, par value $.01
per share of the Company (the "Common Shares") and of any other stock of the
Company ranking junior to the Series D Preferred Stock, shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the last day
of January, April, July, and October in each year (each such date being referred
to herein as a "Dividend Payment Date"), commencing on the first Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series D Preferred Stock, in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $1 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions other than a dividend payable in
Common Shares, declared on the Common Shares since the immediately preceding
Dividend Payment Date or, with respect to the first Dividend Payment Date, since
the first issuance of any share or fraction of a share of Series D Preferred
Stock. In the event the Company shall at any time after November 20, 1998,
declare or pay any dividend on the Common Shares payable in Common Shares, or
effect a subdivision or combination or consolidation of the outstanding Common
Shares (by reclassification or otherwise than by payment of a dividend in Common
Shares) into a greater or lesser number of Common Shares, then in each such case
the amount to which holders of shares of Series D Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction, the numerator of which is
the number of Common Shares outstanding immediately after such event and the
denominator of which is the number of Common Shares that were outstanding
immediately prior to such event.

                  (B) The Company shall declare a dividend or distribution on
the Series D Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Shares
(other than a dividend payable in shares of Common Shares); provided that, in
the event no dividend or distribution shall have been declared on the Common
Shares during the period between any Dividend Payment Date and the next
subsequent Dividend Payment Date, a dividend of $1 per share on the Series D
Preferred Stock shall nevertheless be payable, when, as and if declared, on such
subsequent Dividend Payment Date.

                  (C) Dividends shall begin to accrue and be cumulative, whether
or not earned or declared, on outstanding shares of Series D Preferred Stock
from the Dividend Payment Date next preceding the date of issue of such shares,
unless the date of issue of such shares is prior to the record date for the
first Dividend Payment Date, in which case dividends on such shares shall begin
to accrue from the date of issue of such shares, or unless the date of issue is
a Dividend Payment Date or is a date after the record date for the determination
of holders of shares of Series D Preferred Stock entitled to receive a quarterly
dividend and before such Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Dividend Payment
Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on
the shares of Series D Preferred Stock in an amount less than the total amount
of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Series D Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

                  Section 3. Voting Rights. The holders of shares of Series D
Preferred Stock shall have the following voting rights:

                  (A) Subject to the provision for adjustment hereinafter set
         forth and except as otherwise provided in the Certificate of
         Incorporation or required by law, each share of Series D Preferred
         Stock shall entitle the holder thereof to 100 votes on all matters upon
         which the holders of the Common Shares of the Company are entitled to
         vote. In the event the Company shall at any time after November 20,
         1998, declare or pay any dividend on the Common Shares payable in
         Common Shares, or effect a subdivision or combination or consolidation
         of the outstanding Common Shares (by reclassification or otherwise than
         by payment of a dividend in Common Shares) into a greater or lesser
         number of Common Shares, then in each such case the number of votes per
         share to which holders of shares of Series D Preferred Stock were
         entitled immediately prior to such event shall be adjusted by
         multiplying such number by a fraction, the numerator of which is the
         number of Common Shares outstanding immediately after such event and
         the denominator of which is the number of Common Shares that were
         outstanding immediately prior to such event.

                  (B) Except as otherwise provided herein, in the Certificate of
         Incorporation or in any other Certificate of Designations creating a
         series of Preferred Stock or any similar stock, and except as otherwise
         required by law, the holders of shares of Series D Preferred Stock and
         the holders of Common Shares and any other capital stock of the Company
         having general voting rights shall vote together as one class on all
         matters submitted to a vote of stockholders of the Company.

                  (C) Except as set forth herein, or as otherwise provided by
         law, holders of Series D Preferred Stock shall have no special voting
         rights and their consent shall not be required (except to the extent
         they are entitled to vote with holders of Common Shares as set forth
         herein) for taking any corporate action.

                  Section 4.  Certain Restrictions.

                  (A) Whenever quarterly dividends or other dividends or
         distributions payable on the Series D Preferred Stock as provided in
         Section 2 are in arrears, thereafter and until all accrued and unpaid
         dividends and distributions, whether or not earned or declared, on
         shares of Series D Preferred Stock outstanding shall have been paid in
         full, the Company shall not:

                           (i) declare or pay dividends, or make any other
                  distributions, on any shares of stock ranking junior (as to
                  dividends) to the Series D Preferred Stock;

                           (ii) declare or pay dividends, or make any other
                  distributions, on any shares of stock ranking on a parity (as
                  to dividends) with the Series D Preferred Stock, except
                  dividends paid ratably on the Series D Preferred Stock and all
                  such parity stock on which dividends are payable or in arrears
                  in proportion to the total amounts to which the holders of all
                  such shares are then entitled;

                           (iii) redeem or purchase or otherwise acquire for
                  consideration shares of any stock ranking junior (either as to
                  dividends or upon liquidation, dissolution or winding up) to
                  the Series D Preferred Stock, provided that the Company may at
                  any time redeem, purchase or otherwise acquire shares of any
                  such junior stock in exchange for shares of any stock of the
                  Company ranking junior (as to dividends and upon dissolution,
                  liquidation or winding up) to the Series D Preferred Stock or
                  rights, warrants or options to acquire such junior stock;

                           (iv) redeem or purchase or otherwise acquire for
                  consideration any shares of Series D Preferred Stock, or any
                  shares of stock ranking on a parity (either as to dividends or
                  upon liquidation, dissolution or winding up) with the Series D
                  Preferred Stock, except in accordance with a purchase offer
                  made in writing or by publication (as determined by the Board
                  of Directors) to all holders of such shares upon such terms as
                  the Board of Directors, after consideration of the respective
                  annual dividend rates and other relative rights and
                  preferences of the respective series and classes, shall
                  determine in good faith will result in fair and equitable
                  treatment among the respective series or classes.

                  (B) The Company shall not permit any subsidiary of the Company
         to purchase or otherwise acquire for consideration any shares of stock
         of the Company unless the Company could, under paragraph (A) of this
         Section 4, purchase or otherwise acquire such shares at such time and
         in such manner.

                  Section 5. Reacquired Shares. Any shares of Series D Preferred
Stock purchased or otherwise acquired by the Company in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof.

                  Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (A) to the holders of the Common Shares or of shares of any other stock of
the Company ranking junior, upon liquidation, dissolution or winding up, to the
Series D Preferred Stock unless, prior thereto, the holders of shares of Series
D Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not earned or
declared, to the date of such payment, provided that the holders of shares of
Series D Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
100 times the aggregate amount to be distributed per share to holders of Common
Shares, or (B) to the holders of shares of stock ranking on a parity upon
liquidation, dissolution or winding up with the Series D Preferred Stock, except
distributions made ratably on the Series D Preferred Stock and all such parity
stock in proportion to the total amounts to which the holders of all such shares
are entitled upon such liquidation, dissolution or winding up. In the event the
Company shall at any time after November 20, 1998 declare or pay any dividend on
the Common Shares payable in Common Shares, or effect a subdivision or
combination or consolidation of the outstanding Common Shares (by
reclassification or otherwise than by payment of a dividend in Common Shares)
into a greater or lesser number of Common Shares, then in each such case the
aggregate amount to which holders of shares of Series D Preferred Stock were
entitled immediately prior to such event under the proviso in clause (A) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction


                                       4
<PAGE>


the numerator of which is the number of Common Shares outstanding immediately
after such event and the denominator of which is the number of Common Shares
that were outstanding immediately prior to such event.

                  Section 7. Consolidation, Merger, etc. In case the Company
shall enter into any consolidation, merger, combination or other transaction in
which the Common Shares are converted into, exchanged for or changed into other
stock or securities, cash and/or any other property, then in any such case each
share of Series D Preferred Stock shall at the same time be similarly converted
into, exchanged for or changed into an amount per share (subject to the
provision for adjustment hereinafter set forth) equal to 100 times the aggregate
amount of stock, securities, cash and/or any other property (payable in kind),
as the case may be, into which or for which each Common Share is converted,
exchanged or converted. In the event the Company shall at any time after
November 20, 1998 declare or pay any dividend on the Common Shares payable in
Common Shares, or effect a subdivision or combination or consolidation of the
outstanding Common Shares (by reclassification or otherwise than by payment of a
dividend in Common Shares) into a greater or lesser number of Common Shares,
then in each such case the amount set forth in the preceding sentence with
respect to the conversion, exchange or change of shares of Series D Preferred
Stock shall be adjusted by multiplying such amount by a fraction, the numerator
of which is the number of Common Shares outstanding immediately after such event
and the denominator of which is the number of Common Shares that were
outstanding immediately prior to such event.

                  Section 8. No Redemption. The shares of Series D Preferred
Stock shall not be redeemable from any holder.

                  Section 9. Rank. The Series D Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up of the Company, junior to all other
series of Preferred Stock and senior to the Common Shares.

                  Section 10. Amendment. If any proposed amendment to the
Certificate of Incorporation (including this Certificate of Designations) would
alter, change or repeal any of the preferences, powers or special rights given
to the Series D Preferred Stock so as to affect the Series D Preferred Stock
adversely, then the holders of the Series D Preferred Stock shall be entitled to
vote separately as a class upon such amendment, and the affirmative vote of
two-thirds of the outstanding shares of the Series D Preferred Stock, voting
separately as a class, shall be necessary for the adoption thereof, in addition
to such other vote as may be required by the General Corporation Law of the
State of Delaware.

                                    ---------

                  Section 1. Number and Election of Directors. (a) The Board of
Directors shall consist of 15 members. Except as provided in Sections 1 and 2 of
this Article, directors shall be elected by a plurality of the votes cast at

                  (b) Notwithstanding anything in this Section 1 or in Section 2
of this Article III to the contrary, each of the holders of the series C
preferred stock, par value $0.01 per share (the "Series C Preferred Stock"), of

Section 1(c) not made or adopted in accordance with the procedures set forth in
this Section 1(c) shall be void. Any amendment to this Section l(c) shall
require the vote of holders of not less than two-thirds of the shares of stock
entitled to vote thereon.

directorships resulting from any increase in the authorized number of directors
shall be filled by a majority vote of all directors, including the Series C
Directors, as defined in Section 1 of this Article III, or by a sole remaining
director, and the directors so chosen shall hold office until the next annual
election and until their successors are duly elected and qualified, or until
their earlier resignation or removal; provided, however, that:

                  (a) Any interim vacancy among the Series C Directors, whether
         such vacancy occurs as a result of death, removal or otherwise, shall
         be filled, effective at the beginning of the next meeting of the Board
         of Directors, by a designee nominated by the Union, as defined in the
         Certificate of Designation for the Series C Preferred Stock (the
         "Series C Certificate of Designation"), that nominated the previous
         holder of the vacant position pursuant to the terms of the Letter
         Agreements (as defined below); provided, however, that for any vacancy
         among the Series C Directors created by an increase in the size of the

         Pilots Association, the International Brotherhood of Teamsters and the

         acting through its President or, in the case of Airline Pilots
         Association, the Northwest Airlines, Inc. Master Executive Council,
         shall each be entitled to nominate one-third of the Series C Directors
         and if the total number of Series C Directors is not a multiple of
         three, any remaining Series C Directors shall be nominated by a
         unanimous vote of the existing Series C Directors designated by such
         three Unions.

                  (b) In the event that, in connection with the redemption of
         Series C Preferred Stock pursuant to paragraph 9(i)(a) of the Series C
         Certificate of Designation, the


                                       4

         Corporation issues additional shares of Common Stock to the exchanging
         holders of Series C Preferred Stock and, following such issuance, the
         number of shares of Common Stock held by Qualified Holders of Employee
         Stock, as such terms are defined in the Series C Certificate of
         Designation, after such redemption is greater than 50% of the number of

         terms of all sitting members of the Board of Directors of the
         Corporation, other than the Series C Directors, shall thereupon

management of the business and affairs of the Corporation to the extent lawful
under the General Corporation Law of the State of Delaware, provided, however,
to the extent that directors serve as members of a committee designated by the
Board of Directors, at least one of such directors shall be a Series C Director
as long as any Series C Directors sit on the Board of Directors.

                  Section 4. Duties and Powers. The business of the Corporation
shall be managed by or under the direction of the Board of Directors which may

thereof stating the place, date and hour of the meeting shall be given to each
director either by mail not less than forty-eight (48) hours before the date of
the meeting, by telephone or telegram on twenty-four (24) hours' notice, or on

the Corporation's Certificate of Incorporation or these Bylaws may not be
amended to abrogate any of the terms or rights or powers of the Series C
Preferred Stock in a manner inconsistent with the terms of the Letter

satisfactory to the Board of Directors for the faithful performance of the
duties of his or her office and for the restoration to the Corporation, in case

certificate, the Board of Directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or

stockholders or any adjournment thereof, or entitled to receive payment of any

not it shall have express or other notice thereof, except as otherwise provided
by law.

law, the Certificate of Incorporation or these Bylaws, to be given to any
director, member of a committee or stockholder, such notice may be given by

by law, the Certificate of Incorporation or these Bylaws, to be given to any
director, member of a committee or stockholder, a waiver thereof in writing,
signed by the person entitled to notice, whether before or after the time stated
therein, shall be deemed equivalent to notice. Attendance of a person at a
meeting shall constitute a waiver of notice of such meeting, except when the
person attends a meeting for the express purpose of objecting, at the beginning
of the meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor the
purpose of, any regular or special meeting or the stockholders, directors, or
members of a committee of directors need be specified in any written notice
unless so required by the Certificate of Incorporation or these Bylaws.

                               GENERAL PROVISIONS

available for dividends such sum or sums as the Board of Directors from time to
time, in its absolute discretion, deems proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the Corporation, or for any proper purpose, and the Board of
Directors may modify or abolish any such reserve.

                  Section 2. Disbursements. All checks or demands for money and

Series C Certificate of Designation, may only be made if a majority of the
Series C Directors consent to such decision.

                  (b) Any decision by the Board of Directors of the Corporation
on any Partial Repurchase Date, as defined in the Series C Certificate of
Designation, not to use all Available Cash as defined in the Series C

                                  ARTICLE VIII

                                 INDEMNIFICATION
                                 ---------------

                  Section 1. Power to Indemnify in Actions, Suits or Proceedings
Other than Those by or in the Right of the Corporation. Subject to Section 4 of
this Article VIII, the Corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he or she is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he or she reasonably believed to be in
or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had reasonable cause to believe that his or
her conduct was unlawful.

<PAGE>



                  Section 2. Power to Indemnify in Actions, Suits or Proceedings
by or in the Right of the Corporation. Subject to Section 4 of this Article
VIII, the Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he or she is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against expenses (including attorneys'
fees) actually and reasonably incurred by him or her in connection with the
defense or settlement of such action or suit if he or she acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the Corporation; except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable for gross negligence or willful misconduct to the
Corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

                  Section 3. Notwithstanding the other provisions of this
Article VIII, to the extent that a director, officer, employee or agent of the
Corporation has been successful on the merits or otherwise, including without
limitation the dismissal of an action without prejudice, in the defense of any
action, suit or proceeding referred to in Sections 2 and 3 above, or in the
defense of any claim, issue or matter therein, that person shall be indemnified
against all costs, charges and expenses (including attorneys' fees) actually and
reasonably incurred by that person or on that person's behalf in connection
therewith.

                  Section 4. Authorization of Indemnification. Any
indemnification under this Article VIII (unless ordered by a court) shall be
made by the Corporation unless a determination is made (i) by the Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, or (ii) if such a quorum is not
obtainable, or, even if obtainable a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (iii) by the
stockholders, that indemnification of the director, officer, employee or agent
is not proper because that person has not met the applicable standards of
conduct set forth in Sections 1 and 2 above.

                  Section 5. Good Faith Defined. For purposes of any
determination under this Article VIII, a person shall be deemed to have acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the Corporation, or, with respect to any criminal
action or proceeding, to have had no reasonable cause to believe his or her
conduct was unlawful, if his or her action is based on the records or books of
account of this Corporation or another enterprise, or on information supplied to
him or her by the officers of the Corporation or another enterprise in the
course of their duties, or on the advice of legal counsel for the Corporation or
another enterprise or on information or record given or reports made to the
Corporation or another enterprise by an independent certified public accountant
or by an appraiser or other expert selected with reasonable care by the
Corporation or another enterprise. The term "another enterprise" as used in this
Section 5 shall mean any other

                                       13
<PAGE>



corporation or any partnership, joint venture, trust or other enterprise of
which such person is or was serving at the request of the Corporation as a
director, officer, employee or agent. The provisions of this Section 5 shall not
be deemed to be exclusive or to limit in any way the circumstances in which a
person may be deemed to have met the applicable standard of conduct set forth in
Sections 1 and 2 of this Article VIII, as the case may be.

                  Section 6. Indemnification by a Court. Notwithstanding any
contrary determination in the specific case under Section 4 of this Article
VIII, and notwithstanding the absence of any determination thereunder, any
director, officer, employee or agent may apply to any court of competent
jurisdiction in the State of Delaware for indemnification to the extent
otherwise permissible under Sections 1 and 2 of this Article VIII. The basis of
such indemnification by a court shall be a determination by such court that
indemnification of the director, officer, employee or agent is proper in the
circumstances because he or she has met the applicable standards of conduct set
forth in Sections 1 and 2 of this Article VIII, as the case may be. Notice of
any application for indemnification pursuant to this Section 6 shall be given to
the Corporation promptly upon the filing of such application.

                  Section 7. Advance of Costs, Charges and Expenses. Costs,
charges and expenses (including attorneys' fees) incurred by a person referred
to in Sections 1 and 2 above in defending a civil or criminal action, suit or
proceeding (including investigations by any government agency and all costs,
charges and expenses incurred in preparing for any threatened action, suit or
proceeding) shall be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding; provided however, that the payment of such
costs, charges and expenses incurred by a director or officer in that person's
capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer) in
advance of the final disposition of such action, suit or proceeding shall be
made only upon receipt of an undertaking by or on behalf of the director or
officer to repay all amounts so advanced in the event that it shall ultimately
be determined that such director or officer is not entitled to be indemnified by
the Corporation as authorized in this Article VIII. No security be required for
such undertaking and such undertaking shall be accepted without reference to the
recipient's financial ability to make repayment. The repayment of such charges
and expenses incurred by other employees and agents of the Corporation which are
paid by the Corporation in advance of the final disposition of such action, suit
or proceeding as permitted by this Section 7 may be required upon such terms and
conditions, if any, as the Board of Directors deems appropriate. The Board of
Directors may, in the manner set forth above, and subject to the approval of
such director, officer, employee or agent of the Corporation, authorize the
Corporation's counsel to represent such person, in any action, suit or
proceeding, whether or not the Corporation is party to such action, suit or
proceeding.

                  Section 8. Procedure for Indemnification. Any indemnification
under Sections 1, 2 or 3 or advance of costs, charges and expenses under Section
7 of this Article VIII shall be made promptly, and in any event, within sixty
(60) days, upon the written request of the director, officer, employer or agent
directed to the Secretary of the Corporation. The right to indemnification or
advances granted in this Article VIII shall be enforceable by the director,
officer, employer or agent in any court of competent jurisdiction if the
Corporation denies such request, in whole or part, or if no disposition thereof
is made within sixty (60) days. Such

                                       14
<PAGE>



person's costs and expenses incurred in connection with successfully
establishing that person's right to indemnification or advances, in whole or in
part, in any such action shall also be indemnified by the Corporation. It shall
be a defense to any such action (other than an action brought to enforce a claim
for advance costs, charges and expenses under Section 7 of this Article VIII
where the required undertaking, if any, has been received by the Corporation)
that the claimant has not met the standard of conduct set forth in Sections 1 or
2 of this Article VIII, but the burden of proving such standard of conduct has
not been met shall be on the Corporation. Neither the failure of the Corporation
(including its Board of Directors, its independent legal counsel and its
stockholders) to have made such a determination prior to the commencement of
such action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in
Sections 1 and 2 of this Article VIII, nor the fact that there has been an
actual determination by the Corporation (including its Board of Directors, its
independent legal counsel and its stockholders) that the claimant has not met
such applicable standard, shall be a defense to the action or create a
presumption that the claimant has not met the applicable standard of conduct.

                  Section 9. Non-Exclusivity of Indemnification and Advancement
of Expenses. The indemnification and advancement of expenses provided by or
granted pursuant to this Article VIII shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled under any Bylaw, agreement, contract, vote of stockholders or
disinterested directors or pursuant to the direction (howsoever embodied) of any
court of competent jurisdiction or otherwise, both as to action in his or her
official capacity and as to action in another capacity while holding such
office, it being the policy of the Corporation that indemnification of the
persons specified in Sections 1 and 2 of this Article VIII shall be made to the
fullest extent permitted by law. The provisions of this Article VIII shall not
be deemed to preclude the indemnification of any person who is not specified in
Sections 1 or 2 of this Article VIII but whom the Corporation has the power or
obligation to indemnify under the provisions of the General Corporation Law of
the State of Delaware, or otherwise.

                  Section 10. Insurance. The Corporation may purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him or her and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the Corporation would
have the power or the obligation to indemnify him or her against such liability
under the provisions of this Article VIII.

                  Section 11. Meaning of "Corporation" for Purposes of Article
VIII. For purposes of this Article VIII, references to "the Corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers and employees or agents, so that
any person who is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request for such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall stand
in the same


                                       15
<PAGE>



position under the provisions of this Article VIII with respect to the resulting
or surviving corporation as he or she would have with respect to such
constituent corporation if its separate existence had continued.

                  Section 12. Survival of Indemnification and Advancement of
Expenses. The indemnification and advancement of expenses provided by, or
granted pursuant to, this section shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.


                                   ARTICLE IX

                          OWNERSHIP BY FOREIGN PERSONS
                          ----------------------------

          Section 1. Foreign Stock Record. There shall be maintained a
separate stock record, designated the "Foreign Stock Record", for the
registration of Alien Owned Shares. The Beneficial Ownership by Persons of Alien
Owned Shares shall be determined in conformity with regulations prescribed by
the Board of Directors.

                  Section 2. Permitted Percentage. At no time shall ownership of
shares representing more than the Permitted Percentage be registered on the
Foreign Stock Record.

                  Section 3. Registration of Shares. If at any time there exist
Alien Owned Shares that are not registered on the Foreign Stock Record, the
Beneficial Owner thereof may request, in writing, that the Corporation register
ownership of such shares on the Foreign Stock Record and the Corporation shall
comply with such request, subject to the limitation set forth in Section 2. The
order in which Alien Owned Shares shall be registered on the Foreign Stock
Record shall be chronological, based on the date the Corporation received a
written request to so register such shares of Alien Owned Shares; provided, that
any Person who is not a U.S. Citizen who purchases or otherwise acquires Alien
Owned Shares that are registered on the Foreign Stock Record, may register such
shares in its own name within thirty days of such acquisition, in which event
such Person will assume the position of the seller of such shares in the
chronological order of shares registered on the Foreign Stock Record. If at any
time the Corporation shall find that the combined voting power of Alien Owned
Shares then registered on the Foreign Stock Record exceeds the Permitted
Percentage, there shall be removed from the Foreign Stock Record the
registration of such number of shares so registered as is sufficient to reduce
the combined voting power of the shares so registered to an amount not in excess
of the Permitted Percentage. The order in which such shares shall be removed
shall be reverse chronological order based upon the date the Corporation
received a written request to so register such shares of Alien Owned Shares.

                  Section 4. Definitions. Capitalized terms used in this Article
IX and not defined herein shall have the meaning ascribed to them in the
Certificate of Incorporation.

Ladies and Gentlemen:

     We have acted as your counsel in connection with the Registration 
Statement on Form S-3 (the "Registration Statement") of Northwest Airlines 
Corporation (formerly Newbridge Parent Corporation), a Delaware corporation 
(the "Company"), which the Company intends to file with the Securities and 
Exchange Commission under the Securities Act of 1933, as amended (the "Act"), 
relating to, among other things, 2,631,784 shares of the Company's common 
stock, par value $.01 per share (the "Shares"), issued pursuant to an 
Investment Agreement dated as of January 25, 1998, as amended by Amendment 
No. 1 dated as of February 27, 1998 and Amendment No. 2 dated as of November

Partners, L.P. (the "Partnership"), the partners of the Partnership signatory 
thereto, 1998 CAI Partners, L.P., Bonderman Family Limited Partnership, 1992

     We have examined a copy of the Registration Statement (including the 
exhibits thereto) and originals, or duplicates or certified or conformed 
copies, of such corporate records, documents or other instruments of the 
Company and have made such other and further investigations as we deemed 
necessary to enable us to express the opinion hereinafter set forth.

     In such examination, we have assumed the genuineness of all signatures, 
the legal capacity of natural persons, the authenticity of all documents 
submitted to us as originals, the conformity to original documents of all 
documents submitted to us as duplicates or certified or conformed copies, and 
the authenticity of the originals of such documents.

     Based upon the foregoing, and subject to the qualifications and 
limitations stated herein, we are of the opinion that the Shares have been 
duly authorized by the Company and are validly issued, fully paid and 
nonassessable.

     We are members of the Bar of the State of New York, and we do not 
express any opinion herein concerning any law other than the law of the State 
of New York, the federal law of the United States of America and the Delaware 
General Corporation Law.

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the reference of this firm appearing in the

                               Very truly yours,
