Item 5.  Other Events.

          On November 16, 1995, the Board of Directors of Northwest Airlines
Corporation (the "Company") authorized and declared a dividend of one preferred
share purchase right (an "Original Right") for each outstanding share of Class A
Common Stock, par value $.01 per share, of the Company and Class B Common Stock,
par value $.01 per share, of the Company.  The dividend was paid to the
stockholders of record as of the close of business on November 27, 1995.  On
June 25, 1998 the Board of Directors amended the Original Rights in their
entirety to represent a right (a "Right") to purchase one one-hundredth of a
share of Series D Junior Participating Preferred Stock, par value $.01 per share
(the "Preferred Stock") of the Company at a price of $150 per one one-hundredth
of a share of Preferred Stock (as the same may be adjusted, the "Purchase
Price").  The description and terms of the Rights are set forth in an Amended
and Restated Rights Agreement dated as of June 25, 1998, as the same may be
amended from time to time (the "Rights Agreement"), between the Company 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 of a number of Common
Shares 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 sum of (a)
the Common Shares then issued and outstanding, (b) all Common Shares issuable
pursuant to the Northwest Airlines Employee Stock Plan (the "Plan") to trusts
established pursuant to the Plan (the "Trusts"), (c) all Common Shares issuable
upon conversion of all the shares of Series C Preferred Stock, par value $.01
per share, issued or issuable to the Trusts pursuant to the Plan, (d) all Common
Shares issuable upon the exercise of all employee stock options issued and
outstanding as of the date of this Agreement and (e) any other Common Shares not
then actually issued and outstanding but which such Person would be deemed to
beneficially own hereunder (together, the "outstanding Common Shares") or (ii)
10 business days (or such later date as may be determined by action of the Board
of Directors 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
Common Shares equal to 19% or more of the number of outstanding Common Shares
(the earlier of such dates being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate together
with a copy of the Summary of Rights.

          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 Common Shares.  Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Common Share certificates issued
after the Record Date upon transfer or new issuances of Common Shares (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 



<PAGE>



of any certificates for Common Shares outstanding as of the Record Date, even
without such notation or a copy of this Summary of Rights, will also constitute
the transfer of the Rights associated with the Common Shares 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 Shares 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 the Company, in each case as described below.

          The Purchase Price payable, and the number of shares of 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
Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-current market price of the Preferred Stock or (iii) upon the
distribution to holders of the Preferred Stock of evidences of indebtedness or
assets (excluding regular periodic cash dividends or dividends payable in
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 Shares or a stock dividend on the Common
Shares payable in Common Shares or subdivisions, consolidations or combinations
of the Common Shares occurring, in any such case, prior to the Distribution
Date.

          Shares of Preferred Stock purchasable upon exercise of the Rights will
not be redeemable.  Each share of 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 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 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 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 


                                          2
<PAGE>


of Common Shares (or one one-hundredths of a share of 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, the Company 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 the Company has engaged in the foregoing transaction (or
its 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 Common Shares equal to 50% or more of the number of outstanding Common
Shares, the Board of Directors of the Company 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 Common Share, or one one-hundredth of a
share of Preferred Stock (or of a share of a class or series of the Company'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 Preferred Stock will be issued
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock, which may, at the election of the Company, be
evidenced by depositary receipts) and in lieu thereof, an adjustment in cash
will be made based on the market price of the 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 the Company 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, the Company may, except
with respect to the redemption price, amend the Rights in any manner.  After the
Rights are no longer redeemable the Company 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 the Company, including, without limitation, the right
to vote or to receive dividends.

                        AMENDED AND RESTATED RIGHTS AGREEMENT


          Amended and Restated Rights Agreement, dated as of June 25, 1998,
between Northwest Airlines Corporation, a Delaware corporation (the "Company"),
and Norwest Bank Minnesota, N.A., a New York corporation (the "Rights Agent").

          The Company and the Rights Agent have heretofore entered into a Rights
Agreement dated as of November 16, 1995 (the "Original Rights Agreement").  In
connection therewith, the Board of Directors of the Company authorized and
declared a dividend of one preferred share purchase right (the "Original Right")
for each share of Common Stock (as hereinafter defined) of the Company
outstanding as of the close of business on November 27, 1995 (the "Record
Date"), and the Board of Directors further authorized and directed the issuance
of one Original Right (subject to adjustment as provided herein) with respect to
each share of Common Stock that shall become outstanding between the Record Date
and the earliest of the Distribution Date, the Redemption Date and the Final
Expiration Date (as such terms are hereinafter defined), with each Original
Right having the rights assigned to it under the Original Rights Agreement. 
Pursuant to Section 27 of the Original Rights Agreement, the parties hereto
hereby amend and restate the Original Rights Agreement to read in its entirety
in the form hereof (as amended and restated, the "Agreement").  The Board of
Directors of the Company has approved the amendment and restatement such that
each Original Right shall be deemed to be a preferred share purchase right (a
"Right") having the rights assigned to it pursuant to this Agreement.  The Board
of Directors has also authorized the issuance of one Right (as such number may
be adjusted hereafter pursuant to the terms of this Agreement) with respect to
each Common Share that shall become outstanding between the date of this
Agreement and the earliest to occur of the Distribution Date, the Redemption 



<PAGE>




Date or the Final Expiration Date.  Each Right shall represent the right to
purchase one one-hundredth (1/100) of a share of Preferred Stock. 

          Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

          Section 1.  Certain Definitions.  For purposes of this Agreement, the
following terms have the meaning indicated:

          (a)  "Acquiring Person" shall mean any Person (as such term is
     hereinafter defined) who or which shall be the Beneficial Owner (as such
     term is hereinafter defined) of a number of Common Shares equal to 19% or
     more of the number of Common Shares (as such term is hereinafter defined)
     then outstanding (or, if such Person is an Institutional Investor (as such
     term is hereinafter defined), 25% or more of the Common Shares then
     outstanding), but shall not include an Exempt Person (as such term is
     hereinafter defined); provided, however, that if the Board of Directors of
     the Company determines in good faith that a Person who would otherwise be
     an "Acquiring Person" has become such inadvertently (including, without
     limitation, because (i) such Person was unaware that it beneficially owned
     a number of Common Shares that would otherwise cause such Person to be a
     "Acquiring Person" or (ii) such Person was aware of the extent of its
     Beneficial Ownership of Common Shares but had no actual knowledge of the
     consequences of such Beneficial Ownership under this Rights Agreement) and
     without any intention of changing or influencing control of the Company,
     and such Person, as promptly as practicable divested or divests himself or
     itself of Beneficial Ownership of a sufficient number of Common Shares so
     that such Person would no longer be an Acquiring Person, then such Person
     shall not be deemed 



                                          2
<PAGE>



     to be or to have become an "Acquiring Person" for any purposes of this
     Agreement.  Notwithstanding the foregoing, (i) if a Person would otherwise
     be deemed an Acquiring Person upon the adoption of this Agreement, such
     Person will not be deemed an Acquiring Person for any purposes of this
     Agreement unless and until such Person acquires Beneficial Ownership of any
     additional Common Shares after the adoption of this Agreement, unless upon
     the consummation of the acquisition of such additional Common Shares such
     Person does not beneficially own a number of Common Shares equal to 19% or
     more (25% or more in the case of an Institutional Investor) of the number
     of Common Shares then outstanding, and (ii) no Person shall become an
     "Acquiring Person" as the result of an acquisition of Common Shares by the
     Company which, by reducing the number of shares outstanding, increases the
     proportionate number of Common Shares beneficially owned by such Person to
     19% or more (25% or more in the case of an Institutional Investor) of the
     number of Common Shares then outstanding, provided, however, that if a
     Person shall become the Beneficial Owner of a number of Common Shares equal
     to 19% or more (25% or more in the case of an Institutional Investor) of
     the number of Common Shares then outstanding by reason of such share
     acquisitions by the Company and thereafter become the Beneficial Owner of
     any additional Common Shares, then such Person shall be deemed to be an
     "Acquiring Person" unless upon the consummation of the acquisition of such
     additional Common Shares such Person does not beneficially own a number of
     Common Shares equal to 19% or more (25% or more in the case of an
     Institutional Investor) of the number of Common Shares then outstanding. 
     Notwithstanding any of the foregoing, in the event that an Institutional
     Investor (who 


                                          3
<PAGE>


     is the Beneficial Owner of more than 19% of the Common Shares then
     outstanding at any time after the date hereof) no longer satisfies the
     requirements set forth in the definition of "Institutional Investor" set
     forth below, then such Person shall promptly as practicable, but in no
     event later than 5 Business Days after the Board of Directors determines in
     good faith that such Person no longer meets the requirements set forth in
     the definition of "Institutional Investor",  divest itself of a sufficient
     number of Common Shares so that such Person no longer beneficially owns
     more than 19% of the Common Shares then outstanding.  If such Person does
     not divest itself of Common Shares in accordance with the requirements set
     forth in the prior sentence, then such Person shall be deemed to be or to
     have become an "Acquiring Person" for any purposes of this Agreement.   The

the "Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of Section 3(b) hereof) by the certificates for Common Shares
registered in the names of the holders thereof and not by separate Right
Certificates, and (y) the Rights will be transferable only in connection with
the transfer of the Common Shares.  As soon as practicable after the
Distribution Date, the Company will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid mail, to each
record holder of Common Shares as of the close of business on the Distribution
Date (other than any Acquiring Person or any Associate or Affiliate of an
Acquiring Person), at the address of such holder shown on the records of the
Company, a Right Certificate, in substantially the form of Exhibit B hereto (a
"Right Certificate"), evidencing one Right 


                                          11
<PAGE>


(subject to adjustment as provided herein) for each Common Share so held.  As of
the Distribution Date, the Rights will be evidenced solely by such Right
Certificates.   

          (b)  Following the Record Date, the Company sent a copy of a Summary
of Rights to Purchase Shares of Preferred Stock (the "Summary of Rights") by
first-class, postage-prepaid mail, to each record holder of Common Shares as of
the close of business on the Record Date (other than any Acquiring Person or any
Associate or Affiliate of any Acquiring Person), at the address of such holder
shown on the records of the Company.  With respect to certificates for Common
Shares outstanding as of the Record Date, until the Distribution Date, the
Rights will be evidenced by such certificates registered in the names of the
holders thereof together with the Summary of Rights.  Until the Distribution
Date (or the earlier of the Redemption Date or the Final Expiration Date), the
surrender for transfer of any certificate for Common Shares outstanding on the
Record Date, with or without a copy of the Summary of Rights, shall also
constitute the transfer of the Rights associated with the Common Shares
represented thereby.

          (c)  Certificates issued for Common Shares (including, without
limitation, upon conversion of the Series C Preferred Stock, disposition of
Common Shares out of treasury stock or issuance or reissuance of Common Shares
out of authorized but unissued shares) after the date hereof but prior to the
earliest of the Distribution Date, the Redemption Date or the Final Expiration
Date shall have impressed on, printed on, written on or otherwise affixed to
them the following legend:

          This certificate also evidences and entitles the holder hereof to
          certain rights as set forth in an Amended and Restated Rights
          Agreement between Northwest Airlines Corporation and Norwest Bank
          Minnesota, N.A., dated as of June 25, 1998 as the same may be
          amended from time to time (the "Rights Agreement"), the terms of
          which are hereby incorporated herein by reference 


                                          12
<PAGE>


          and a copy of which is on file at the principal executive offices of
          Northwest Airlines Corporation.  Under certain circumstances, as set
          forth in the Rights Agreement, such Rights will be evidenced by
          separate certificates and will no longer be evidenced by this
          certificate.  Northwest Airlines Corporation will mail to the holder
          of this certificate a copy of the Rights Agreement without charge
          after receipt of a written request therefor.  Under certain
          circumstances, as set forth in the Rights Agreement, Rights owned by
          or transferred to any Person who becomes an Acquiring Person (as
          defined in the Rights Agreement) and certain transferees thereof will
          become null and void and will no longer be transferable.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.  In the event that the Company purchases or
otherwise acquires any Common Shares after the Record Date but prior to the
Distribution Date (including pursuant to the conversion of shares), any Rights
associated with such Common Shares shall be deemed cancelled and retired so that
the Company shall not be entitled to exercise any Rights associated with the
Common Shares which are no longer outstanding.  

          Notwithstanding this paragraph (c), the omission of a legend shall not
affect the enforceability of any part of this Agreement or the rights of any
holder of the Rights.

          Section 4.  Form of Right Certificates.  The Right Certificates (and
the forms of election to purchase shares and of assignment to be printed on the
reverse thereof) shall be substantially in the form set forth in Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this 


                                          13
<PAGE>


Agreement, or as may be required to comply with any applicable law or with any
rule or regulation made pursuant thereto or with any rule or regulation of the
NASDAQ Stock Market or of any other stock exchange or automated quotation system
on which the Rights may from time to time be listed, or to conform to usage. 
Subject to the provisions of Sections 11, 13 and 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such number of one
one-hundredths of a share of Preferred Stock as shall be set forth therein at
the price per one one-hundredth of a share of Preferred Stock set forth therein
(the "Purchase Price"), but the number of such one one-hundredths of a share of
Preferred Stock and the Purchase Price shall be subject to adjustment as
provided herein.

          Section 5.  Countersignature and Registration. (a)  The Right 
Certificates shall be executed on behalf of the Company by the President, any 
of the Vice Presidents, the Treasurer or the Controller of the Company, 
either manually or by facsimile signature, shall have affixed thereto the 
Company's seal or a facsimile thereof, and shall be attested by the Secretary 
or an Assistant Secretary of the Company, either manually or by facsimile 
signature. The Right Certificates shall be manually countersigned by the 
Rights Agent and shall not be valid for any purpose unless countersigned. In 
case any officer of the Company who shall have signed any of the Right 
Certificates shall cease to be such officer of the Company before 
countersignature by the Rights Agent and issuance and delivery by the 
Company, such Right Certificates, nevertheless, may be countersigned by the 
Rights Agent and issued and delivered by the Company with the same force and 
effect as though the Person who signed such Right Certificates had not ceased 
to be such officer of the Company; and any Right Certificate may be signed on 
behalf of the Company by any Person who, at the actual date of the execution 
of such Right 

                                          14
<PAGE>


Certificate, shall be a proper officer of the Company to sign such Right
Certificate, although at the date of the execution of this Agreement any such
Person was not such an officer.

          (b) Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at an office or agency designated for such purpose, books for
registration and transfer of the Right Certificates issued hereunder.  Such
books shall show the names and addresses of the respective holders of the Right
Certificates, the number of Rights evidenced on its face by each of the Right
Certificates and the date of each of the Right Certificates.

          Section 6.  Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. (a) 
Subject to the provisions of Sections 7(e), 11(a)(ii) and 14 hereof, at any time
after the close of business on the Distribution Date, and prior to the close of
business on the earlier of the Redemption Date or the Final Expiration Date, any
Right Certificate or Right Certificates may be transferred, split up, combined
or exchanged for another Right Certificate or Right Certificates, entitling the
registered holder to purchase a like number of one one-hundredths of a share of
Preferred Stock as the Right Certificate or Right Certificates surrendered then
entitled such holder to purchase.  Any registered holder desiring to transfer,
split up, combine or exchange any Right Certificate or Right Certificates shall
make such request in writing delivered to the Rights Agent, and shall surrender
the Right Certificate or Right Certificates to be transferred, split up,
combined or exchanged at the office or agency of the Rights Agent designated for
such purpose.  Thereupon the Rights Agent shall countersign and deliver to the
Person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested.  The Company may require payment of a sum sufficient to
cover any tax or governmental charge 


                                          15
<PAGE>


that may be imposed in connection with any transfer, split up, combination or
exchange of Right Certificates.

          (b)  Subject to the provisions of Section 11(a)(ii) hereof, at any
time after the Distribution Date and prior to the close of business on the
earlier of the Redemption Date or the Final Expiration Date, upon receipt by the
Company and the Rights Agent of evidence reasonably satisfactory to them of the
loss, theft, destruction or mutilation of a Right Certificate, and, in case of
loss, theft or destruction, of indemnity or security reasonably satisfactory to
them, and, at the Company's request, reimbursement to the Company and the Rights
Agent of all reasonable expenses incidental thereto, and upon surrender to the
Rights Agent and cancellation of the Right Certificate if mutilated, the Company
will make and deliver a new Right Certificate of like tenor to the Rights Agent
for delivery to the registered holder in lieu of the Right Certificate so lost,
stolen, destroyed or mutilated.

          Section 7.  Exercise of Rights, Purchase Price; Expiration Date of
Rights. (a)  Except as otherwise provided herein, the Rights shall become
exercisable on the Distribution Date, and thereafter the registered holder of
any Right Certificate may, subject to Section 11(a)(ii) hereof and except as
otherwise provided herein, exercise the Rights evidenced thereby in whole or in
part upon surrender of the Right Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the
office or agency of the Rights Agent designated for such purpose, together with
payment of the Purchase Price for each one one-hundredth of a share of Preferred
Stock as to which the Rights are exercised, at any time which is both after the
Distribution Date and prior to the earliest of (i) the close of business on
November 16, 2005 (the "Final Expiration Date"), (ii) 


                                          16

"Redemption Date") or (iii) the time at which such Rights are exchanged as
provided in Section 24 hereof.

          (b)  The Purchase Price shall be initially $150 for each one
one-hundredth of a share of Preferred Stock purchasable upon the exercise of a
Right.  The Purchase Price and the number of one one-hundredths of a share of
Preferred Stock or other securities or property to be acquired upon exercise of
a Right shall be subject to adjustment from time to time as provided in Sections
11 and 13 hereof and shall be payable in lawful money of the United States of
America in accordance with paragraph (c) of this Section 7.

          (c)  Except as otherwise provided herein, upon receipt of a Right
Certificate representing exercisable Rights, with the form of election to
purchase duly executed, accompanied by payment of the aggregate Purchase Price
for the shares of Preferred Stock to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof, in cash or by certified check,
cashier's check or money order payable to the order of the Company, the Rights
Agent shall thereupon promptly (i) (A) requisition from any transfer agent of
the Preferred Stock certificates for the number of shares of Preferred Stock to
be purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) requisition from the depositary agent
depositary receipts representing interests in such number of one one-hundredths
of a share of Preferred Stock as are to be purchased (in which case certificates
for the Preferred Stock represented by such receipts shall be deposited by the
transfer agent with the depositary agent) and the Company hereby directs the
depositary agent to comply with such request, (ii) when appropriate, requisition
from the Company the amount of cash to be paid in lieu of issuance of fractional
shares in accordance with Section 14 


                                          17

receipts, cause the same to be delivered to or upon the order of the registered
holder of such Right Certificate, registered in such name or names as may be
designated by such holder and (iv) when appropriate, after receipt, promptly
deliver such cash to or upon the order of the registered holder of such Right

          (d)  Except as otherwise provided herein, in case the registered

evidenced thereby, a new Right Certificate evidencing Rights equivalent to the
exercisable Rights remaining unexercised shall be issued by the Rights Agent to
the registered holder of such Right Certificate or to his duly authorized
assigns, subject to the provisions of Section 14 hereof.

          (e)  Notwithstanding anything in this Agreement to the contrary,
neither the Rights Agent nor the Company shall be obligated to undertake any
action with respect to a registered holder of Rights upon the occurrence of any
purported transfer or exercise of Rights pursuant to Section 6 hereof or this
Section 7 unless such registered holder shall have (i) completed and signed the
certificate contained in the form of assignment or election to purchase set
forth on the reverse side of the Rights Certificate surrendered for such
transfer or exercise and (ii) provided such additional evidence of the identity
of the Beneficial Owner (or former Beneficial Owner) thereof as the Company
shall reasonably request.     

          Section 8.  Cancellation and Destruction of Right Certificates.  All
Right Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right
Certificates shall be issued in lieu thereof except as expressly 


                                          18
<PAGE>


permitted by any of the provisions of this Agreement.  The Company shall deliver
to the Rights Agent for cancellation and retirement, and the Rights Agent shall
so cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof.  The Rights Agent shall
deliver all cancelled Right Certificates to the Company.

          Section 9.  Availability of Shares of Preferred Stock. (a)  The
Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued shares of Preferred Stock or any
shares of Preferred Stock held in its treasury, the number of shares of
Preferred Stock that will be sufficient to permit the exercise in full of all
outstanding Rights.

          (b)  So long as the shares of Preferred Stock (and, following the time
that a Person becomes an Acquiring Person, Common Shares and other securities)
issuable upon the exercise of Rights may be listed or admitted to trading on the
NASDAQ Stock Market or listed on any other national securities exchange or
quotation system, the Company shall use its best efforts to cause, from and
after such time as the Rights become exercisable, all shares reserved for such
issuance to be listed or admitted to trading on the NASDAQ Stock Market or
listed on any other exchange or quotation system upon official notice of
issuance upon such exercise.

          (c)  From and after such time as the Rights become exercisable, the
Company shall use its best efforts, if then necessary to permit the issuance of
shares of Preferred Stock (and following the time that a Person first becomes an
Acquiring 

                                          19
<PAGE>


Person, Common Shares and other securities) upon the exercise of Rights, to
register and qualify such shares of Preferred Stock (and following the time that
a Person first becomes an Acquiring Person, Common Shares and other securities)
under the Securities Act and any applicable state securities or "Blue Sky" laws
(to the extent exemptions therefrom are not available), cause such registration
statement and qualifications to become effective as soon as possible after such
filing and keep such registration and qualifications effective until the earlier
of the date as of which the Rights are no longer exercisable for such securities
and the Final Expiration Date.  The Company may temporarily suspend, for a
period of time not to exceed 90 days, the exercisability of the Rights in order
to prepare and file a registration statement under the Securities Act and permit
it to become effective.  Upon any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect.  Notwithstanding any provision of this
Agreement to the contrary, the Rights shall not be exercisable in any
jurisdiction unless the requisite qualification in such jurisdiction shall have
been obtained and until a registration statement under the Securities Act (if
required) shall have been declared effective.

          (d)  The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all shares of Preferred Stock (and,
following the time that a Person becomes an Acquiring Person, Common Shares and
other securities) delivered upon exercise of Rights shall, at the time of
delivery of the certificates therefor (subject to payment of the Purchase
Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

          (e)  The Company further covenants and agrees that it will pay when
due and payable any and all federal and state transfer taxes and charges which
may be payable in respect of the issuance or delivery of the Right Certificates
or of any shares of Preferred 

                                          20
<PAGE>


Stock (or Common Shares or other securities) upon the exercise of Rights.  The
Company shall not, however, be required to pay any transfer tax which may be
payable in respect of any transfer or delivery of Right Certificates to a Person
other than, or the issuance or delivery of certificates or depositary receipts
for the Preferred Stock (or Common Shares or other securities) in a name other
than that of, the registered holder of the Right Certificate evidencing Rights
surrendered for exercise or to issue or deliver any certificates or depositary
receipts for Preferred Stock (or Common Shares or other securities) upon the
exercise of any Rights until any such tax shall have been paid (any such tax
being payable by that holder of such Right Certificate at the time of surrender)
or until it has been established to the Company's reasonable satisfaction that
no such tax is due.

          Section 10.  Preferred Stock Record Date.  Each Person in whose name
any certificate for Preferred Stock is issued upon the exercise of Rights shall
for all purposes be deemed to have become the holder of record of the shares of
Preferred Stock represented thereby on, and such certificate shall be dated, the
date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Stock transfer books of the Company
are closed, such Person shall be deemed to have become the record holder of such
shares on, and such certificate shall be dated, the next succeeding Business Day
on which the Preferred Stock transfer books of the Company are open.  Prior to
the exercise of the Rights evidenced thereby, the holder of a Right Certificate
shall not be entitled to any rights of a holder of Preferred Stock for which the
Rights shall be exercisable, including, without limitation, the 

                                          21
<PAGE>


right to vote or to receive dividends or other distributions, and shall not be
entitled to receive any notice of any proceedings of the Company, except as
provided herein.

          Section 11.  Adjustment of Purchase Price, Number of Shares and Number
of Rights.  The Purchase Price, the number of shares of Preferred Stock or other
securities or property purchasable upon exercise of each Right and the number of
Rights outstanding are subject to adjustment from time to time as provided in
this Section 11.

          (a)(i)  In the event the Company shall at any time after the date of
          this Agreement (A) declare a dividend on the Preferred Stock payable
          in shares of Preferred Stock, (B) subdivide the outstanding Preferred
          Stock, (C) combine the outstanding Preferred Stock into a smaller
          number of Preferred Stock or (D) issue any shares of its capital stock
          in a reclassification of the Preferred Stock (including any such
          reclassification in connection with a consolidation or merger in which
          the Company is the continuing or surviving corporation), except as
          otherwise provided in this Section 11(a), the Purchase Price in effect
          at the time of the record date for such dividend or of the effective
          date of such subdivision, combination or reclassification, and the
          number and kind of shares of capital stock issuable on such date,
          shall be proportionately adjusted so that the holder of any Right
          exercised after such time shall be entitled to receive the aggregate
          number and kind of shares of capital stock which, if such Right had
          been exercised immediately prior to such date and at a time when the
          Preferred Stock transfer books of the Company were open, the holder
          would have owned upon such exercise and been entitled to receive by
          virtue of such dividend, subdivision, combination or reclassification;
          provided, however, that in no 


                                          22
<PAGE>


          event shall the consideration to be paid upon the exercise of one
          Right be less than the aggregate par value of the shares of capital
          stock of the Company issuable upon exercise of one Right.

               (ii)  Subject to Section 24 of this Agreement and except as
          otherwise provided in this Section 11(a)(ii), in the event any Person
          becomes an Acquiring Person, each holder of a Right shall thereafter
          have the right to receive, upon exercise thereof at a price equal to
          the then current Purchase Price multiplied by the number of one
          one-hundredths of a share of Preferred Stock for which a Right is then
          exercisable, in accordance with the terms of this Agreement and in
          lieu of shares of Preferred Stock, such number of Common Shares (or at
          the option of the Company, such number of one one-hundredths of shares
          of Preferred Stock) as shall equal the result obtained by (x)
          multiplying the then current Purchase Price by the number of one
          one-hundredths of a share of Preferred Stock for which a Right is then
          exercisable and dividing that product by (y) 50% of the then current
          per share market price of the Company's Common Shares (determined
          pursuant to Section 11(d) hereof) on the date of the occurrence of
          such event; provided, however, that the Purchase Price and the number
          of Common Shares so receivable upon exercise of a Right shall
          thereafter be subject to further adjustment as appropriate in
          accordance with Section 11(f) hereof.  Notwithstanding anything in
          this Agreement to the contrary, however, from and after the time (the
          "invalidation time") when any Person first becomes an Acquiring
          Person, any Rights that are beneficially owned by (x) any Acquiring 


                                          23
<PAGE>



          Person (or any Affiliate or Associate of any Acquiring Person), (y) a
          transferee of any Acquiring Person (or any such Affiliate or
          Associate) who becomes a transferee after the invalidation time or (z)
          a transferee of any Acquiring Person (or any such Affiliate or
          Associate) who became a transferee prior to or concurrently with the
          invalidation time pursuant to either (I) a transfer from the Acquiring
          Person to holders of its equity securities or to any Person with whom
          it has any continuing agreement, arrangement or understanding
          regarding the transferred Rights or (II) a transfer which the Board of
          Directors has determined is part of a plan, arrangement or
          understanding which has the purpose or effect of avoiding the
          provisions of this paragraph, and subsequent transferees of such
          Persons, shall be void without any further action and any holder of
          such Rights shall thereafter have no rights whatsoever with respect to
          such Rights under any provision of this Agreement.  The Company shall
          use all reasonable efforts to ensure that the provisions of this
          Section 11(a)(ii) are complied with, but shall have no liability to
          any holder of Right Certificates or other Person as a result of its
          failure to make any determinations with respect to an Acquiring Person
          or its Affiliates, Associates or transferees hereunder.  From and
          after the invalidation time, no Right Certificate shall be issued
          pursuant to Section 3 or Section 6 hereof that represents Rights that
          are or have become void pursuant to the provisions of this paragraph,
          and any Right Certificate delivered to the Rights Agent that
          represents Rights that are or have become void pursuant to the
          provisions of this paragraph shall be cancelled.  From and after the
          occurrence of an event specified in Section 13(a) hereof, 


                                          24
<PAGE>


          any Rights that theretofore have not been exercised pursuant to this
          Section 11(a)(ii) shall thereafter be exercisable only in accordance
          with Section 13 and not pursuant to this Section 11(a)(ii).

               (iii)  The Company may at its option substitute for a Common
          Share issuable upon the exercise of Rights in accordance with the
          foregoing subparagraph (ii) such number or fractions of shares of
          Preferred Stock having an aggregate current market value equal to the
          current per share market price of Common Shares.  In the event that
          there shall not be sufficient Common Shares issued but not outstanding
          or authorized but unissued to permit the exercise in full of the
          Rights in accordance with the foregoing subparagraph (ii), the Board
          of Directors shall, to the extent permitted by applicable law and any
          material agreements then in effect to which the Company is a party (A)
          determine the excess of (1) the value of the Common Shares issuable
          upon the exercise of a Right in accordance with the foregoing
          subparagraph (ii) (the "Current Value") over (2) the then current
          Purchase Price multiplied by the number of one one-hundredths of
          shares of Preferred Stock for which a Right was exercisable
          immediately prior to the time that the Acquiring Person became such
          (such excess, the "Spread"), and (B) with respect to each Right (other
          than Rights which have become void pursuant to Section 11(a)(ii)),
          make adequate provision to substitute for the Common Shares issuable
          in accordance with subparagraph (ii) upon exercise of the Right and
          payment of the applicable Purchase Price, (1) cash, (2) a reduction in
          the Purchase Price, (3) shares of Preferred Stock or other equity
          securities of the Company (including, 


                                          25
<PAGE>



          without limitation, shares or fractions of shares of preferred stock
          which, by virtue of having dividend, voting and liquidation rights
          substantially comparable to those of the Common Shares, are deemed in
          good faith by the Board of Directors to have substantially the same
          value as the Common Shares (such shares of preferred stock and shares
          or fractions of shares of preferred stock are hereinafter referred to
          as "Common Share equivalents"), (4) debt securities of the Company,
          (5) other assets, or (6) any combination of the foregoing, having a
          value which, when added to the value of the Common Shares actually
          issued upon exercise of such Right, shall have an aggregate value
          equal to the Current Value (less the amount of any reduction in the
          Purchase Price), where such aggregate value has been determined by the
          Board of Directors upon the advice of a nationally recognized
          investment banking firm selected in good faith by the Board of
          Directors; provided, however, if the Company shall not make adequate
          provision to deliver value pursuant to clause (B) above within thirty
          (30) days following the date that the Acquiring Person became such
          (the "Section 11(a)(ii) Trigger Date"), then the Company shall be
          obligated to deliver, to the extent permitted by applicable law and
          any material agreements then in effect to which the Company is a
          party, upon the surrender for exercise of a Right and without
          requiring payment of the Purchase Price, Common Shares (to the extent
          available), and then, if necessary, such number or fractions of shares
          of Preferred Stock (to the extent available) and then, if necessary,
          cash, which shares and/or cash have an aggregate value equal to the
          Spread.  If, upon the date any Person becomes an Acquiring Person, the
          Board 


                                          26
<PAGE>


          of Directors shall determine in good faith that it is likely that
          sufficient additional Common Shares could be authorized for issuance
          upon exercise in full of the Rights, then, if the Board of Directors
          so elects, the thirty (30) day period set forth above may be extended
          to the extent necessary, but not more than ninety (90) days after the
          Section 11(a)(ii) Trigger Date, in order that the Company may seek
          stockholder approval for the authorization of such additional shares
          (such thirty (30) day period, as it may be extended, is herein called
          the "Substitution Period").  To the extent that the Company determines
          that some action need be taken pursuant to the second and/or third
          sentence of this Section 11(a)(iii), the Company (x) shall provide,
          subject to Section 11(a)(ii) hereof and the last sentence of this
          Section 11(a)(iii) hereof, that such action shall apply uniformly to
          all outstanding Rights and (y) may suspend the exercisability of the
          Rights until the expiration of the Substitution Period in order to
          seek any authorization of additional shares and/or to decide the
          appropriate form of distribution to be made pursuant to such second
          sentence and to determine the value thereof.  In the event of any such
          suspension, the Company shall issue a public announcement stating that
          the exercisability of the Rights has been temporarily suspended, as
          well as a public announcement at such time as the suspension is no
          longer in effect.  For purposes of this Section 11(a)(iii), the value
          of the Common Shares shall be the current per share market price (as
          determined pursuant to Section 11(d)(i)) on the Section 11(a)(ii)
          Trigger Date and the per share or fractional value of any "Common
          Share equivalent" shall be deemed to equal the current per share
          market price 

                                          27

          of the Common Shares.  The Board of Directors of the Company may, but
          shall not be required to, establish procedures to allocate the right
          to receive Common Shares upon the exercise of the Rights among holders
          of Rights pursuant to this Section 11(a)(iii).

          (b)  In case the Company shall fix a record date for the issuance of
     rights, options or warrants to all holders of Preferred Stock entitling
     them (for a period expiring within 45 calendar days after such record date)
     to subscribe for or purchase Preferred Stock (or shares having the same
     rights, privileges and preferences as the Preferred Stock ("equivalent
     preferred shares")) or securities convertible into Preferred Stock or
     equivalent preferred shares at a price per share of Preferred Stock or
     equivalent preferred shares (or having a conversion price per share, if a
     security convertible into shares of Preferred Stock or equivalent preferred
     shares) less than the then current per share market price of the Preferred
     Stock (determined pursuant to Section 11(d) hereof) on such record date,
     the Purchase Price to be in effect after such record date shall be
     determined by multiplying the Purchase Price in effect immediately prior to
     such record date by a fraction, the numerator of which shall be the number
     of shares of Preferred Stock and equivalent preferred shares outstanding on
     such record date plus 


                                          28
<PAGE>


     the number of shares of Preferred Stock and equivalent preferred shares
     which the aggregate offering price of the total number of shares of
     Preferred Stock and/or equivalent preferred shares so to be offered (and/or
     the aggregate initial conversion price of the convertible securities so to
     be offered) would purchase at such current market price, and the
     denominator of which shall be the number of shares of Preferred Stock and
     equivalent preferred shares outstanding on such record date plus the number
     of additional shares of Preferred Stock and/or equivalent preferred shares
     to be offered for subscription or purchase (or into which the convertible
     securities so to be offered are initially convertible); provided, however,
     that in no event shall the consideration to be paid upon the exercise of
     one Right be less than the aggregate par value of the shares of capital
     stock of the Company issuable upon exercise of one Right.  In case such
     subscription price may be paid in a consideration part or all of which
     shall be in a form other than cash, the value of such consideration shall
     be as determined in good faith by the Board of Directors of the Company,
     whose determination shall be described in a statement filed with the Rights
     Agent.  Shares of Preferred Stock and equivalent preferred shares owned by
     or held for the account of the Company shall not be deemed outstanding for
     the purpose of any such computation.  Such adjustment shall be made
     successively whenever such a record date is fixed; and in the event that
     such rights, options or warrants are not so issued, the Purchase Price
     shall be adjusted to be the Purchase Price which would then be in effect if
     such record date had not been fixed.

          (c)  In case the Company shall fix a record date for the making of a
     distribution to all holders of the Preferred Stock (including any such
     distribution made in connection with a consolidation or merger in which the
     Company is the continuing or surviving corporation) of evidences of
     indebtedness or assets (other than a regular quarterly cash dividend or a
     dividend payable in Preferred Stock) or subscription rights or warrants
     (excluding those referred to in Section 11(b) hereof), the Purchase Price
     to be in effect after such record date shall be determined by multiplying
     the Purchase Price in effect immediately prior to such record date by a
     fraction, the numerator of 

                                          29
<PAGE>


     which shall be the then current per share market price of the Preferred
     Stock (determined pursuant to Section 11(d) hereof) on such record date,
     less the fair market value (as determined in good faith by the Board of
     Directors of the Company whose determination shall be described in a
     statement filed with the Rights Agent) of the portion of the assets or
     evidences of indebtedness so to be distributed or of such subscription
     rights or warrants applicable to one share of Preferred Stock, and the
     denominator of which shall be such current per share market price
     (determined pursuant to Section 11(d) hereof) of the Preferred Stock;
     provided, however, that in no event shall the consideration to be paid upon
     the exercise of one Right be less than the aggregate par value of the
     shares of capital stock of the Company to be issued upon exercise of one
     Right.  Such adjustments shall be made successively whenever such a record
     date is fixed; and in the event that such distribution is not so made, the
     Purchase Price shall again be adjusted to be the Purchase Price which would
     then be in effect if such record date had not been fixed.

          (d)(i)  Except as otherwise provided herein, for the purpose of any
     computation hereunder, the "current per share market price" of any security
     (a "Security" for the purpose of this Section 11(d)(i)) on any date shall
     be deemed to be the average of the daily closing prices per share of such
     Security for the 30 consecutive Trading Days (as such term is hereinafter
     defined) immediately prior to such date; provided, however, that in the
     event that the current per share market price of the Security is determined
     during a period following the announcement by the issuer of such Security
     of (A) a dividend or distribution on such Security payable in shares of
     such Security or securities convertible into such shares, or (B) any 


                                          30
<PAGE>


     subdivision, combination or reclassification of such Security, and prior to
     the expiration of 30 Trading Days after the ex-dividend date for such
     dividend or distribution, or the record date for such subdivision,
     combination or reclassification, then, and in each such case, the current
     per share market price shall be appropriately adjusted to reflect the
     current market price per share equivalent of such Security.  The closing
     price for each day shall be the last sale price, regular way, or, in case
     no such sale takes place on such day, the average of the closing bid and
     asked prices, regular way, in either case as reported by the principal
     consolidated transaction reporting system with respect to securities listed
     or admitted to trading on the NASDAQ Stock Market or, if the Security is
     not listed or admitted to trading on the NASDAQ Stock Market, as reported
     in the principal consolidated transaction reporting system with respect to
     securities listed on the principal national securities exchange on which
     the Security is listed or admitted to trading or, if the Security is not
     listed or admitted to trading on any national securities exchange, the last
     quoted price or, if not so quoted, the average of the high bid and low
     asked prices in the over-the-counter market or such other system then in
     use, or, if on any such date the Security is not quoted by any organization
     in the over-the-counter market, the average of the closing bid and asked
     prices as furnished by a professional market maker making a market in the
     Security selected by the Board of Directors of the Company.  The term
     "Trading Day" shall mean a day on which the principal national securities
     exchange on which the Security is listed or admitted to trading is open for
     the transaction of business or, if the Security is not listed or admitted
     to trading on any national securities exchange, a Business Day.

          (ii) For the purpose of any computation hereunder, if the Preferred
     Stock is publicly traded, the "current per share market price" of the
     Preferred Stock shall be determined in accordance with the method set forth
     in Section 11(d)(i).  If the Preferred Stock is not publicly traded but the
     Common Shares are publicly traded, the "current per share market price" of
     the Preferred Stock shall be conclusively deemed to be the current per
     share market price of the Common Shares as determined pursuant to Section
     11(d)(i) multiplied by one hundred (appropriately adjusted to reflect any
     stock split, stock dividend or similar transaction occurring after the date
     hereof).  If neither the Common Shares nor the Preferred Stock is publicly
     traded, "current per share market price" shall mean the fair value per
     share as determined in good faith by the Board of Directors of the Company,
     whose determination shall be described in a statement filed with the Rights
     Agent.

          (e) No adjustment in the Purchase Price shall be required unless such
     adjustment would require an increase or  decrease of at least 1% in the
     Purchase Price; provided, however, that any adjustments which by reason of
     this Section 11(e) are not required to be made shall be carried forward and
     taken into account in any subsequent adjustment.  All calculations under
     this Section 11 shall be made to the nearest cent or to the nearest one
     ten-thousandth of a share of Preferred Stock or Common Share or other share
     or security as the case may be.  Notwithstanding the first sentence of this
     Section 11(e), any adjustment required by this Section 11 shall be made no
     later than the earlier of (i) three years from the date of the transaction
     which requires such adjustment or (ii) the date of the expiration of the
     right to exercise any Rights.

                                          32

          (f)  If as a result of an adjustment made pursuant to Section 11(a)
     hereof, the holder of any Right thereafter exercised shall become entitled
     to receive any shares of capital stock of the Company other than the
     Preferred Stock, thereafter the Purchase Price and the number of such other
     shares so receivable upon exercise of a Right shall be subject to
     adjustment from time to time in a manner and on terms as nearly equivalent
     as practicable to the provisions with respect to the Preferred Stock
     contained in Sections 11(a), 11(b), 11(c), 11(e), 11(h), 11(i) and 11(m)
     and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to
     the Preferred Stock shall apply on like terms to any such other shares.

          (g)  All Rights originally issued by the Company subsequent to any
     adjustment made to the Purchase Price hereunder shall evidence the right to
     purchase, at the adjusted Purchase Price, the number of one one-hundredths
     of a share of Preferred Stock purchasable from time to time hereunder upon
     exercise of the Rights, all subject to further adjustment as provided
     herein.

          (h) Unless the Company shall have exercised its election as provided
     in Section 11(i), upon each adjustment of the Purchase Price as a result of
     the calculations made in Sections 11(b) and (c), each Right outstanding
     immediately prior to the making of such adjustment shall thereafter
     evidence the right to purchase, at the adjusted Purchase Price, that number
     of one one-hundredths of a share of Preferred Stock (calculated to the
     nearest one ten- thousandth of a share of Preferred Stock) obtained by (i)
     multiplying (x) the number of one one-hundredths of a share covered by a
     Right immediately prior to such adjustment by (y) the Purchase Price in
     effect immediately prior to such adjustment of the Purchase Price and (ii)
     dividing the 


                                          33
<PAGE>


     product so obtained by the Purchase Price in effect immediately after such
     adjustment of the Purchase Price.

          (i)  The Company may elect on or after the date of any adjustment of
     the Purchase Price to adjust the number of Rights, in substitution for any
     adjustment in the number of one one-hundredths of a share of Preferred
     Stock purchasable upon the exercise of a Right.  Each of the Rights
     outstanding after such adjustment of the number of Rights shall be
     exercisable for the number of one one-hundredths of a share of Preferred
     Stock for which a Right was exercisable immediately prior to such
     adjustment.  Each Right held of record prior to such adjustment of the
     number of Rights shall become that number of Rights (calculated to the
     nearest one ten-thousandth) obtained by dividing the Purchase Price in
     effect immediately prior to adjustment of the Purchase Price by the
     Purchase Price in effect immediately after adjustment of the Purchase
     Price.  The Company shall make a public announcement of its election to
     adjust the number of Rights, indicating the record date for the adjustment,
     and, if known at the time, the amount of the adjustment to be made.  This
     record date may be the date on which the Purchase Price is adjusted or any
     day thereafter, but, if the Right Certificates have been issued, shall be
     at least 10 days later than the date of the public announcement.  If Right
     Certificates have been issued, upon each adjustment of the number of Rights
     pursuant to this Section 11(i), the Company may, as promptly as
     practicable, cause to be distributed to holders of record of Right
     Certificates on such record date Right Certificates evidencing, subject to
     Section 14 hereof, the additional Rights to which such holders shall be
     entitled as a result of such adjustment, or, at the option of the Company,
     shall cause to be 

                                          34
<PAGE>


     distributed to such holders of record in substitution and replacement for
     the Right Certificates held by such holders prior to the date of
     adjustment, and upon surrender thereof, if required by the Company, new
     Right Certificates evidencing all the Rights to which such holders shall be
     entitled after such adjustment.  Right Certificates so to be distributed
     shall be issued, executed and countersigned in the manner provided for
     herein and shall be registered in the names of the holders of record of
     Right Certificates on the record date specified in the public announcement.

          (j)  Irrespective of any adjustment or change in the Purchase Price or
     the number of one one-hundredths of a share of Preferred Stock issuable
     upon the exercise of the Rights, the Right Certificates theretofore and
     thereafter issued may continue to express the Purchase Price and the number
     of one one-hundredths of a share of Preferred Stock which were expressed in
     the initial Right Certificates issued hereunder.

          (k)  Before taking any action that would cause an adjustment reducing
     the Purchase Price below the then par value, if any, of the Preferred Stock
     or other shares of capital stock issuable upon exercise of the Rights, the
     Company shall take any corporate action which may, in the opinion of its
     counsel, be necessary in order that the Company may validly and legally
     issue fully paid and nonassessable shares of Preferred Stock or other such
     shares at such adjusted Purchase Price.

          (l) In any case in which this Section 11 shall require that an
     adjustment in the Purchase Price be made effective as of a record date for
     a specified event, the Company may elect to defer until the occurrence of
     such event the issuing to the holder of any Right exercised after such
     record date of the Preferred Stock and other capital stock or securities of
     the Company, if any, issuable upon such exercise over 


                                          35
<PAGE>


     and above the Preferred Stock and other capital stock or securities of the
     Company, if any, issuable upon such exercise on the basis of the Purchase
     Price in effect prior to such adjustment; provided, however, that the
     Company shall deliver to such holder a due bill or other appropriate
     instrument evidencing such holder's right to receive such additional shares
     upon the occurrence of the event requiring such adjustment.

          (m)  Anything in this Section 11 to the contrary notwithstanding, the
     Company shall be entitled to make such reductions in the Purchase Price, in
     addition to those adjustments expressly required by this Section 11, as and
     to the extent that it in its sole discretion shall determine to be
     advisable in order that any consolidation or subdivision of the Preferred
     Stock, issuance wholly for cash of any shares of Preferred Stock at less
     than the current market price, issuance wholly for cash or Preferred Stock
     or securities which by their terms are convertible into or exchangeable for
     Preferred Stock, dividends on Preferred Stock payable in shares of
     Preferred Stock or issuance of rights, options or warrants referred to
     hereinabove in Section 11(b), hereafter made by the Company to holders of
     its Preferred Stock shall not be taxable to such stockholders.

          (n)  Anything in this Agreement to the contrary notwithstanding, in
     the event that at any time after the date of this Agreement and prior to
     the Distribution Date, the Company shall (i) declare or pay any dividend on
     the Common Shares payable in Common Shares or (ii) effect a subdivision,
     combination or consolidation of the Common Shares (by reclassification or
     otherwise than by payment of a dividend payable in Common Shares) into a
     greater or lesser number of Common Shares, then in any such case, the
     number of Rights associated with each Common Share then 

                                          36
<PAGE>


     outstanding, or issued or delivered thereafter, shall be proportionately
     adjusted so that the number of Rights thereafter associated with each
     Common Share following any such event shall equal the result obtained by
     multiplying the number of Rights associated with each Common Share
     immediately prior to such event by a fraction the numerator of which shall
     be the total number of Common Shares outstanding immediately prior to the
     occurrence of the event and the denominator of which shall be the total
     number of Common Shares outstanding immediately following the occurrence of
     such event.

          (o)  The Company agrees that, after the earlier of the Distribution
     Date or the Stock Acquisition Date, it will not, except as permitted by
     Sections 23, 24 or 27 hereof, take (or permit any Subsidiary to take) any
     action if at the time such action is taken it is reasonably foreseeable
     that such action will diminish substantially or eliminate the benefits
     intended to be afforded by the Rights.

          Section 12.  Certificate of Adjusted Purchase Price or Number of
Shares.  Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Stock a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with Section
25 hereof (if so required under Section 25 hereof).  The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained and shall not be deemed to have knowledge of any such adjustment
unless and until it shall have received such certificate.

          Section 13.  Consolidation, Merger or Sale or Transfer of Assets or
Earnings Power.  (a) In the event, directly or indirectly, at any time after any
Person has become an Acquiring Person, (i) the Company shall merge with and into
any other Person, (ii) any Person shall consolidate with the Company, or any
Person shall merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person (or of the Company) or cash or any
other property, or (iii) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person (other than the Company or one or more of its wholly-owned
Subsidiaries), then upon the first occurrence of such event, proper provision
shall be made so that: (A) each holder of record of a Right (other than Rights
which have become void pursuant to Section 11(a)(ii)) shall thereafter have the
right to receive, upon the exercise thereof at a price equal to the then current
Purchase Price multiplied by the number of one one-hundredths of a share of
Preferred Stock for which a Right was exercisable (whether or not such Right was
then exercisable) immediately prior to the time that any Person first became an
Acquiring Person (each as subsequently adjusted thereafter pursuant to Sections
11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)), in accordance with the terms of
this Agreement and in lieu of Preferred Stock, such number of validly issued,
fully paid and non-assessable and freely tradeable shares of Common Stock of the
Principal Party (as defined herein) not subject to any liens, encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the result
obtained by (1) multiplying the 


                                          38
<PAGE>


then current Purchase Price by the number of one one-hundredths of a share of
Preferred Stock for which a Right was exercisable immediately prior to the time
that any Person first became an Acquiring Person (as subsequently adjusted
thereafter pursuant to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m))
and (2) dividing that product by 50% of the then current per share market price
of the Common Stock of such Principal Party (determined pursuant to Section
11(d)(i) hereof) on the date of consummation of such consolidation, merger, sale
or transfer; provided that the Purchase Price and the number of shares of Common
Stock of such Principal Party issuable upon exercise of each Right shall be
further adjusted as provided in Section 11(f) of this Agreement to reflect any
events occurring in respect of such Principal Party after the date of the such
consolidation, merger, sale or transfer; (B) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such consolidation,
merger, sale or transfer, all the obligations and duties of the Company pursuant
to this Agreement; (C) the term "Company" shall thereafter be deemed to refer to
such Principal Party; and (D) such Principal Party shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
shares of Common Stock in accordance with Section 9 hereof) in connection with
such consummation of any such transaction as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to the shares of its Common Stock thereafter deliverable upon
the exercise of the Rights; provided that, upon the subsequent occurrence of any
consolidation, merger, sale or transfer of assets or other extraordinary
transaction in respect of such Principal Party, each holder of a Right shall
thereupon be entitled to receive, upon exercise of a Right and payment of the
Purchase Price as provided in this Section 13(a), such cash, shares, rights,
warrants and other property which such holder would have been entitled to
receive had such holder, at the 



                                          39
<PAGE>


time of such transaction, owned the Common Stock of the Principal Party
receivable upon the exercise of a Right pursuant to this Section 13(a), and such
Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may be necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property.

          (b)  "Principal Party" shall mean

               (i)  in the case of any transaction described in (i) or (ii) of
     the first sentence of Section 13(a) hereof:  (A) the Person that is the
     issuer of the securities into which the shares of Common Shares are
     converted in such merger or consolidation, or, if there is more than one
     such issuer, the issuer the shares of Common Stock of which have the
     greatest aggregate market value of shares outstanding, or (B) if no
     securities are so issued, (x) the Person that is the other party to the
     merger, if such Person survives said merger, or, if there is more than one
     such Person, the Person the shares of Common Stock of which have the
     greatest aggregate market value of shares outstanding or (y) if the Person
     that is the other party to the merger does not survive the merger, the
     Person that does survive the merger (including the Company if it survives)
     or (z) the Person resulting from the consolidation; and

               (ii) in the case of any transaction described in (iii) of the
     first sentence in Section 13(a) hereof, the Person that is the party
     receiving the greatest portion of the assets or earning power transferred
     pursuant to such transaction or transactions, or, if each Person that is a
     party to such transaction or transactions receives the same portion of the
     assets or earning power so transferred or if the Person receiving the
     greatest portion of the assets or earning power cannot be determined, 


                                          40
<PAGE>


     whichever of such Persons as is the issuer of Common Stock having the
     greatest aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Stock of such Person is not at such time or has
not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Stock of which is and has been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person
and the Common Stocks of all of such Persons have been so registered, the term
"Principal Party" shall refer to whichever of such Persons is the issuer of
Common Stock having the greatest aggregate market value of shares outstanding,
or (3) if such Person is owned, directly or indirectly, by a joint venture
formed by two or more Persons that are not owned, directly or indirectly, by the
same Person, the rules set forth in clauses (1) and (2) above shall apply to
each of the owners having an interest in the venture as if the Person owned by
the joint venture was a Subsidiary of both or all of such joint venturers, and
the Principal Party in each such case shall bear the obligations set forth in
this Section 13 in the same ratio as its interest in such Person bears to the
total of such interests.

          (c)  The Company shall not consummate any consolidation, merger, sale
or transfer referred to in Section 13(a) hereof unless prior thereto the Company
and the Principal Party involved therein shall have executed and delivered to
the Rights Agent an agreement confirming that the requirements of Sections 13(a)
and (b) hereof shall promptly be performed in accordance with their terms and
that such consolidation, merger, sale or transfer of assets shall not result in
a default by the Principal Party under this Agreement as the same shall 


                                          41
<PAGE>


have been assumed by the Principal Party pursuant to Sections 13(a) and (b)
hereof and providing that, as soon as practicable after executing such agreement
pursuant to this Section 13, the Principal Party will:

               (i)  prepare and file a registration statement under the
     Securities Act, if necessary, with respect to the Rights and the securities
     purchasable upon exercise of the Rights on an appropriate form, use its
     best efforts to cause such registration statement to become effective as
     soon as practicable after such filing and use its best efforts to cause
     such registration statement to remain effective (with a prospectus at all
     times meeting the requirements of the Securities Act) until the Final
     Expiration Date, and similarly comply with applicable state securities
     laws;

               (ii) use its best efforts, if the Common Stock of the Principal
     Party shall be listed or admitted to trading on the NASDAQ Stock Market or
     on another national securities exchange, to list or admit to trading (or
     continue the listing of) the Rights and the securities purchasable upon
     exercise of the Rights on the NASDAQ Stock Market or such securities
     exchange, or, if the Common Stock of the Principal Party shall not be
     listed or admitted to trading on the NASDAQ Stock Market or a national
     securities exchange, to cause the Rights and the securities receivable upon
     exercise of the Rights to be reported by such other system then in use;

               (iii)  deliver to holders of the Rights historical financial
     statements for the Principal Party which comply in all respects with the
     requirements for registration on Form 10 (or any successor form) under the
     Exchange Act; and


                                          42
<PAGE>


               (iv)  obtain waivers of any rights of first refusal or preemptive
     rights in respect of the Common Stock of the Principal Party subject to
     purchase upon exercise of outstanding Rights.

          (d)  In case the Principal Party has provision in any of its
authorized securities or in its certificate of incorporation or by-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue (other than to holders of
Rights pursuant to this Section 13), in connection with, or as a consequence of,
the consummation of a transaction referred to in this Section 13, shares of
Common Stock of such Principal Party at less than the then current market price
per share thereof (determined pursuant to Section 11(d) hereof) or securities
exercisable for, or convertible into, Common Stock of such Principal Party at
less than such then current market price, or (ii) providing for any special
payment, tax or similar provision in connection with the issuance of the Common
Stock of such Principal Party pursuant to the provisions of Section 13, then, in
such event, the Company hereby agrees with each holder of Rights that it shall
not consummate any such transaction unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing that the provision in question of such
Principal Party shall have been cancelled, waived or amended, or that the
authorized securities shall be redeemed, so that the applicable provision will
have no effect in connection with, or as a consequence of, the consummation of
the proposed transaction.

          (e)  The Company covenants and agrees that it shall not, at any time
after a Person first becomes an Acquiring Person, enter into any transaction of
the type contemplated by (i) - (iii) of Section 13(a) hereof if (x) at the time
of or immediately after such 


                                          43
<PAGE>


consolidation, merger, sale, transfer or other transaction there are any rights,
warrants or other instruments or securities outstanding or agreements in effect
which would substantially diminish or otherwise eliminate the benefits intended
to be afforded by the Rights, (y) prior to, simultaneously with or immediately
after such consolidation, merger, sale, transfer of other transaction, the
stockholders of the Person who constitutes, or would constitute, the Principal
Party for purposes of Section 13(a) hereof shall have received a distribution of
Rights previously owned by such Person or any of its Affiliates or Associates or
(z) the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

          Section 14.  Fractional Rights and Fractional Shares. (a)  The Company
shall not be required to issue fractions of Rights or to distribute Right
Certificates which evidence fractional Rights.  In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right.  For the purposes of this Section 14(a), the current market value of a
whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable.  The closing price for any day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of
the closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the NASDAQ Stock Market or, if the Rights are
not listed or admitted to trading on the NASDAQ Stock Market, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national secu-


                                          44
<PAGE>


rities exchange on which the Rights are listed or admitted to trading or, if the
Rights are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by any
system then in use or, if on any such date the Rights are not quoted by any
organization in the over-the-counter market, the average of the closing bid and
asked prices as furnished by a professional market maker making a market in the
Rights selected by the Board of Directors of the Company.  If on any such date
no such market maker is making a market in the Rights, the fair value of the
Rights on such date as determined in good faith by the Board of Directors of the
Company shall be used.

          (b)  The Company shall not be required to issue fractions of Preferred
Stock (other than fractions which are integral multiples of one one-hundredth of
a share of Preferred Stock) upon exercise of the Rights or to distribute
certificates which evidence fractional shares of Preferred Stock (other than
fractions which are integral multiples of one one-hundredth of a share of
Preferred Stock).  Interests in fractions of Preferred Stock in integral
multiples of one one-hundredth of a share of Preferred Stock may, at the
election of the Company, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Company and a depositary selected by it;
provided, that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the Preferred Stock represented by such
depositary receipts.  In lieu of fractional shares of Preferred Stock that are
not integral multiples of one one-hundredth of a share of Preferred Stock, the
Company shall pay to the registered holders of Right Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one 


                                          45
<PAGE>


share of Preferred Stock.  For the purposes of this Section 14(b), the current
market value of a share of Preferred Stock shall be the closing price of a share
of Preferred Stock (as determined pursuant to Section 11(d)(i) hereof) for the
Trading Day immediately prior to the date of such exercise.

          (c)  The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above).

          Section 15.  Rights of Action.  All rights of action in respect of
this Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), on his own behalf and for his own
benefit, may enforce, and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise act in respect of, his
right to exercise the Rights evidenced by such Right Certificate (or, prior to
the Distribution Date, such Common Shares) in the manner provided in such Right
Certificate and in this Agreement.  Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and will be entitled to specific performance of the
obligations under, and injunctive relief against actual or threatened violations
of, the obligations of any Person subject to this Agreement.

          Section 16.  Agreement of Right Holders.  Every holder of a Right, by
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

          (a)  prior to the Distribution Date, the Rights will be transferable
     only in connection with the transfer of the Common Shares;

          (b)  after the Distribution Date, the Right Certificates are
     transferable only on the registry books of the Rights Agent if surrendered
     at the office or agency of the Rights Agent designated for such purpose,
     duly endorsed or accompanied by a proper instrument of transfer; and

          (c)  the Company and the Rights Agent may deem and treat the Person in
     whose name the Right Certificate (or, prior to the Distribution Date, the
     Common Share certificate) is registered as the absolute owner thereof and
     of the Rights evidenced thereby (notwithstanding any notations of ownership
     or writing on the Right Certificates or the Common Share certificate made
     by anyone other than the Company or the Rights Agent) for all purposes
     whatsoever, and neither the Company nor the Rights Agent shall be affected
     by any notice to the contrary.

          Section 17.  Right Certificate Holder Not Deemed a Stockholder.  No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Stock or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any 


                                          47
<PAGE>


meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in this Agreement), or to receive dividends or subscription rights, or
otherwise, until the Rights evidenced by such Right Certificate shall have been
exercised in accordance with the provisions hereof.

          Section 18.  Concerning the Rights Agent. (a)  The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder.  The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability or expense, incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability arising therefrom, directly or
indirectly.

          (b)  The Rights Agent shall be protected and shall incur no liability
for, or in respect of any action taken, suffered or omitted by it in connection
with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Stock or Common Shares or for other
securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

          Section 19.  Merger or Consolidation or Change of Name of Rights
Agent. (a)  Any corporation into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any corporation succeeding to the
stock transfer or corporate trust powers of the Rights Agent or any successor
Rights Agent, shall be the successor to the Rights Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided, that such corporation would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
hereof.  In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement, any of the Right Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such Right
Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement. 

          (b) In case at any time the name of the Rights Agent shall be changed
and at such time any of the Right Certificates shall have been countersigned but
not delivered the Rights Agent may adopt the countersignature under its prior
name and deliver Right Certificates so countersigned; and in case at that time
any of the Right Certificates shall not have been countersigned, the Rights
Agent may countersign such Right Certificates either in 


                                          49
<PAGE>


its prior name or in its changed name and in all such cases such Right
Certificates shall have the full force provided in the Right Certificates and in
this Agreement.

          Section 20.  Duties of Rights Agent.  The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Right Certificates,
by their acceptance thereof, shall be bound:

          (a)  The Rights Agent may consult with legal counsel (who may be legal
     counsel for the Company), and the opinion of such counsel shall be full and
     complete authorization and protection to the Rights Agent as to any action
     taken or omitted by it in good faith and in accordance with such opinion.

          (b)  Whenever in the performance of its duties under this Agreement
     the Rights Agent shall deem it necessary or desirable that any fact or
     matter be proved or established by the Company prior to taking or suffering
     any action hereunder, such fact or matter (unless other evidence in respect
     thereof be herein specifically prescribed) may be deemed to be conclusively
     proved and established by a certificate signed by any one of the President,
     the Chief Financial Officer or the Secretary of the Company and delivered
     to the Rights Agent; and such certificate shall be full authorization to
     the Rights Agent for any action taken or suffered in good faith by it under
     the provisions of this Agreement in reliance upon such certificate.

          (c) The Rights Agent shall be liable hereunder to the Company and any
     other Person only for its own negligence, bad faith or wilful misconduct.

          (d)  The Rights Agent shall not be liable for or by reason of any of
     the statements of fact or recitals contained in this Agreement or in the
     Right Certificates 

                                          50
<PAGE>


     (except its countersignature thereof) or be required to verify the same,
     but all such statements and recitals are and shall be deemed to have been
     made by the Company only.

          (e) The Rights Agent shall not be under any responsibility in respect
     of the validity of this Agreement or the execution and delivery hereof
     (except the due execution hereof by the Rights Agent) or in respect of the
     validity or execution of any Right Certificate (except its countersignature
     thereof); nor shall it be responsible for any breach by the Company of any
     covenant or condition contained in this Agreement or in any Right
     Certificate; nor shall it be responsible for any change in the
     exercisability of the Rights (including the Rights becoming void pursuant
     to Section 11(a)(ii) hereof) or any adjustment in the terms of the Rights
     (including the manner, method or amount thereof) provided for in Sections
     3, 11, 13, 23 and 24, or the ascertaining of the existence of facts that
     would require any such change or adjustment (except with respect to the
     exercise of Rights evidenced by Right Certificates after receipt of a
     certificate furnished pursuant to Section 12, describing such change or
     adjustment); nor shall it by any act hereunder be deemed to make any
     representation or warranty as to the authorization or reservation of any
     shares of Preferred Stock or other securities to be issued pursuant to this
     Agreement or any Right Certificate or as to whether any shares of Preferred
     Stock or other securities will, when issued, be validly authorized and
     issued, fully paid and nonassessable.

          (f)  The Company agrees that it will perform, execute, acknowledge and
     deliver or cause to be performed, executed, acknowledged and delivered all
     such further and other acts, instruments and assurances as may reasonably
     be required by 

                                          51
<PAGE>


     the Rights Agent for the carrying out or performing by the Rights Agent of
     the provisions of this Agreement.

          (g) The Rights Agent is hereby authorized and directed to accept
     instructions with respect to the performance of its duties hereunder from
     any person reasonably believed by the Rights Agent to be one of the
     President, the Chief Financial Officer or the Secretary of the Company, and
     to apply to such officers for advice or instructions in connection with its
     duties, and it shall not be liable for any action taken or suffered by it
     in good faith in accordance with instructions of any such officer or for
     any delay in acting while waiting for those instructions.  Any application
     by the Rights Agent for written instructions from the Company may, at the
     option of the Rights Agent, set forth in writing any action proposed to be
     taken or omitted by the Rights Agent under this Agreement and the date on
     and/or after which such action shall be taken or such omission shall be
     effective.  The Rights Agent shall not be liable for any action taken by,
     or omission of, the Rights Agent in accordance with a proposal included in
     any such application on or after the date specified in such application
     (which date shall not be less than five Business Days after the date any
     officer of the Company actually receives such application, unless any such
     officer shall have consented in writing to an earlier date) unless, prior
     to taking any such action (or the effective date in the case of an
     omission), the Rights Agent shall have received written instructions in
     response to such application specifying the action to be taken or omitted. 

          (h)  The Rights Agent and any stockholder, director, officer or
     employee of the Rights Agent may buy, sell or deal in any of the Rights or
     other securities of the Company or become pecuniarily interested in any
     transaction in which the Company 


                                          52
<PAGE>


     may be interested, or contract with or lend money to the Company or
     otherwise act as fully and freely as though it were not Rights Agent under
     this Agreement.  Nothing herein shall preclude the Rights Agent from acting
     in any other capacity for the Company or for any other legal entity.

          (i)  The Rights Agent may execute and exercise any of the rights or
     powers hereby vested in it or perform any duty hereunder either itself or
     by or through its attorneys or agents, and the Rights Agent shall not be
     answerable or accountable for any act, default, neglect or misconduct of
     any such attorneys or agents or for any loss to the Company resulting from
     any such act, default, neglect or misconduct, provided reasonable care was
     exercised in the selection and continued employment thereof.

          (j)  If, with respect to any Rights Certificate surrendered to the
     Rights Agent for exercise or transfer, the certificate contained in the
     form of assignment or the form of election to purchase set forth on the
     reverse thereof, as the case may be, has not been completed to certify the
     holder is not an Acquiring Person (or an Affiliate or Associate thereof),
     the Rights Agent shall not take any further action with respect to such
     requested exercise or transfer without first consulting with the Company.

          Section 21.  Change of Rights Agent.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Stock by registered or
certified mail, and, following the Distribution Date, to the holders of the
Right Certificates by first-class mail.  The Company may remove the Rights Agent
or any successor Rights Agent upon 30 days' notice in writing, mailed to the 

                                          53
<PAGE>


Rights Agent or successor Rights Agent, as the case may be, and to each transfer
agent of the Common Shares or Preferred Stock by registered or certified mail,
and, following the Distribution Date, to the holders of the Right Certificates
by first-class mail.  If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent.  If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (who shall,
with such notice, submit his Right Certificate for inspection by the Company),
then the registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent.  Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be a
corporation organized and doing business under the laws of the United States or
any State thereof, which is authorized under such laws to exercise corporate
trust or stock transfer powers and is subject to supervision or examination by
federal or state authority and which has at the time of its appointment as
Rights Agent a combined capital and surplus of at least $50 million.  After
appointment, the successor Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent without further act or deed; but the predecessor Rights Agent shall
deliver and transfer to the successor Rights Agent any property at the time held
by it hereunder, and execute and deliver any further assurance, conveyance, act
or deed necessary for the purpose.  Not later than the effective date of any
such appointment the Company shall file notice thereof in writing with the
predecessor Rights Agent and each transfer agent of the Common Shares or
Preferred Stock, and, following the Distribution Date, mail a notice thereof in
writing to the 

                                          54
<PAGE>


registered holders of the Right Certificates.  Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

          Section 22.  Issuance of New Right Certificates.  Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such forms as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Agreement.  In addition, in
connection with the issuance or sale of Common Shares following the Distribution
Date and prior to the earlier of the Redemption Date and the Final Expiration
Date, the Company may with respect to such Common Shares so issued or sold
pursuant to (i) the exercise of stock options, (ii) under any employee plan or
arrangement, (iii) upon the exercise, conversion or exchange of securities,
notes or debentures issued by the Company or (iv) a contractual obligation of
the Company in each case existing prior to the Distribution Date, issue Rights
Certificates representing the appropriate number of Rights in connection with
such issuance or sale.

          Section 23.  Redemption. (a) The Board of Directors of the Company
may, at any time prior to such time as any Person first becomes an Acquiring
Person, redeem all but not less than all the then outstanding Rights at a
redemption price of $.01 per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(the redemption price being hereinafter referred to as the "Redemption 


                                          55
<PAGE>


Price").  The redemption of the Rights may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish.  The Company may, at its option, pay the Redemption
Price in cash, Common Shares (based on the current market price of the Common
Shares at the time of redemption) or any other form of consideration deemed
appropriate by the Board of Directors.

          (b)  Immediately upon the action of the Board of Directors ordering
the redemption of the Rights pursuant to paragraph (a) of this Section 23 (or at
such later time as the Board of Directors may establish for the effectiveness of
such redemption), and without any further action and without any notice, the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the Redemption Price.  The Company shall
promptly give public notice of any such redemption; provided, however, that the
failure to give, or any defect in, any such notice shall not affect the validity
of such redemption.   Within 10 days after such action of the Board of Directors
ordering the redemption of the Rights (or such later time as the Board of
Directors may establish for the effectiveness of such redemption), the Company
shall mail a notice of redemption to all the holders of the then outstanding
Rights at their last addresses as they appear upon the registry books of the
Rights Agent or, prior to the Distribution Date, on the registry books of the
transfer agent for the Common Shares.  Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice.  Each such notice of redemption shall state the method by which the
payment of the Redemption Price will be made.  

          Section 24.  Exchange. (a)  The Board of Directors of the Company,
may, at its option, at any time after any Person first becomes an Acquiring
Person, exchange all or 

                                          56
<PAGE>


part of the then outstanding and exercisable Rights (which shall not include
Rights that have become void pursuant to the provisions of Section 11(a)(ii)
hereof) for Common Shares (or, at the Company's option, Preferred Stock) at an
exchange ratio of one Common Share (or one one-hundredth of a share of Preferred
Stock) per Right, (such exchange ratio being hereinafter referred to as the
"Exchange Ratio").  Notwithstanding the foregoing, the Board of Directors shall
not be empowered to effect such exchange at any time (1) after any Person (other
than an Exempt Person), together with all Affiliates and Associates of such
Person, becomes the Beneficial Owner of a number of Common Shares equal to 50%
or more of the number of Common Shares then outstanding or (2) after the
occurrence of an event specified in Section 13(a) hereof.

          (b)  Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio.  The
Company shall promptly give public notice of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange.  The Company shall promptly mail a notice
of any such exchange to all of the holders of the Rights so exchanged at their
last addresses as they appear upon the registry books of the Rights Agent.  Any
notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice.  Each such notice of exchange
will state the method by which the exchange of the Common Shares for Rights will
be effected and, in the event of any partial exchange, the number of Rights
which 


                                          57
<PAGE>


will be exchanged.  Any partial exchange shall be effected pro rata based on the
number of Rights (other than Rights which have become void pursuant to the
provisions of Section 11(a)(ii) hereof) held by each holder of Rights.

          (c) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit any exchange of
Rights as contemplated in accordance with this Section 24, the Company may, in
its discretion, take such action as may be necessary to authorize additional
Common Shares for issuance upon exchange of the Rights.  In the event that the
Company shall determine not to take such action or shall, after good faith
effort, be unable to take such action as may be necessary to authorize such
additional Common Shares, the Company shall substitute, to the extent of such
insufficiency, for each Common Share that would otherwise be issuable upon
exchange of a Right, a number of shares of Preferred Stock or fractions thereof
(or equivalent preferred shares as such term is defined in Section 11(b)) having
an aggregate current per share market price (determined pursuant to Section
11(d) hereof) equal to the current per share market price of Common Shares
(determined pursuant to Section 11(d) hereof) as of the date of issuance of such
shares of Preferred Stock or fractions thereof (or equivalent preferred shares).

          (d)  The Company shall not, in connection with any exchange pursuant
to this Section 24, be required to issue fractions of Common Shares or to
distribute certificates which evidence fractional Common Shares.  In lieu of
such fractional Common Shares, the Company shall pay to the registered holders
of the Right Certificates with regard to which such fractional Common Shares
would otherwise be issuable an amount in cash equal to the same fraction of the
current market value of a whole Common Share.  For the purposes of this
paragraph (d), the current market value of a whole Common Share shall be the
closing 


                                          58
<PAGE>


price of a Common Share (as determined pursuant to the second sentence of
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

          Section 25.  Notice of Certain Events. (a) In case the Company shall
at any time after the earlier of the Distribution Date or the Stock Acquisition
Date propose (i) to pay any dividend payable in stock of any class to the
holders of its Preferred Stock or to make any other distribution to the holders
of its Preferred Stock (other than a regular quarterly cash dividend), (ii) to
offer to the holders of its Preferred Stock rights or warrants to subscribe for
or to purchase any additional shares of Preferred Stock or shares of stock of
any class or any other securities, rights or options, (iii) to effect any
reclassification of its Preferred Stock (other than a reclassification involving
only the subdivision of outstanding Preferred Stock), (iv) to effect the
liquidation, dissolution or winding up of the Company, or (v) to declare or pay
any dividend on the Common Shares payable in Common Shares or to effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares),
then, in each such case, the Company shall give to each holder of a Right
Certificate, in accordance with Section 26 hereof, a notice of such proposed
action, which shall specify the record date for the purposes of such stock
dividend, or distribution of rights or warrants, or the date on which such
liquidation, dissolution or winding up is to take place and the date of
participation therein by the holders of the Common Shares and/or Preferred
Stock, if any such date is to be fixed, and such notice shall be so given in the
case of any action covered by clause (i) or (ii) above at least 10 days prior to
the record date for determining holders of the Preferred Stock for purposes of
such action, and in the case of any such other action, at least 10 days prior to
the 

                                          59
<PAGE>


date of the taking of such proposed action or the date of participation therein
by the holders of the Common Shares and/or Preferred Stock, whichever shall be
the earlier.

          (b) In case any event described in Section 11(a)(ii) or Section 13
shall occur then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate (or if occurring prior to the Distribution
Date, the holders of the Common Shares) in accordance with Section 26 hereof, a
notice of the occurrence of such event, which notice shall describe such event
and the consequences of such event to holders of Rights under Section 11(a)(ii)
and Section 13 hereof.

          Section 26.  Notices.  Notices or demands authorized by this Agreement
to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed (until another address is filed in
writing with the Rights Agent) as follows:

               Eagan, Minnesota  55121
               Attention: Secretary

Subject to the provisions of Section 21 hereof, any notice or demand authorized
by this Agreement to be given or made by the Company or by the holder of any
Right Certificate to or on the Rights Agent shall be sufficiently given or made
if sent by first-class mail, postage prepaid, addressed (until another address
is filed in writing with the Company) as follows:

               Attention: Secretary  

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Right Certificate shall be
sufficiently given or made if 


                                          60
<PAGE>


sent by first-class mail, postage prepaid, addressed to such holder at the
address of such holder as shown on the registry books of the Company.

          Section 27.  Supplements and Amendments.  Except as otherwise provided
in this Section 27, for so long as the Rights are then redeemable, the Company
may in its sole and absolute discretion, and the Rights Agent shall if the
Company so directs, supplement or amend any provision of this Agreement in any
respect without the approval of any holders of the Rights.  At any time when the
Rights are no longer redeemable, except as otherwise provided in this Section
27, the Company may, and the Rights Agent shall, if the Company so directs,
supplement or amend this Agreement without the approval of any holders of Rights
Certificates in order to (i) cure any ambiguity, (ii) correct or supplement any
provision contained herein which may be defective or inconsistent with any other
provisions herein, (iii) shorten or lengthen any time period hereunder, or (iv)
change or supplement the provisions hereunder in any manner which the Company
may deem necessary or desirable; provided that no such supplement or amendment
shall adversely affect the interests of the holders of Rights as such (other
than an Acquiring Person or an Affiliate or Associate of an Acquiring Person),
and no such amendment may cause the rights again to become redeemable or cause
the Agreement again to become amendable other than in accordance with this
sentence.  Notwithstanding anything contained in this Agreement to the contrary,
no supplement or amendment shall be made that decreases the Redemption Price. 
Upon the delivery of a certificate from an appropriate officer of the Company
which states that the proposed supplement or amendment is in compliance with the

                            NORTHWEST AIRLINES CORPORATION

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

                                 ___________________



          Northwest Airlines 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 at a meeting duly called and
held on November 16, 1995:

          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.


                                         A-1

          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 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 16, 1995, 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 


                                         A-2
<PAGE>


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 16, 1995, 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 

                                         A-3
<PAGE>


     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 


                                         A-4
<PAGE>


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 16, 1995 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
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 16, 1995
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.

          This certifies that ___________ or registered assigns, is the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the
Amended and Restated Rights Agreement, dated as of June 25, 1998, as the same

one-hundredth of a share of Preferred Stock (the "Purchase Price"), upon

Certificate (and the number of one one-hundredths of a share of Preferred Stock
which may be purchased upon exercise hereof) set forth above, and the Purchase
Price set forth above, are the number and Purchase Price as of November 16,
1995, based on the Preferred Stock as constituted at such date.  As provided in
the Rights Agreement, the Purchase Price, the number of one one-hundredths of a
share of Preferred Stock (or other securities or property) which may be
purchased upon the exercise of the Rights and the number of Rights evidenced by
this Right Certificate are subject to modification and adjustment upon the
happening of certain events.

          This Right Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,

          This Right Certificate, with or without other Right Certificates, upon
surrender at the office or agency of the Rights Agent designated for such
purpose, may be exchanged for another Right Certificate or Right Certificates of
like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of shares of Preferred Stock as the Rights evidenced by the
Right Certificate or Right Certificates surrendered shall have entitled such
holder to purchase.  If this Right Certificate shall be exercised in part, the
holder shall be entitled to receive upon surrender hereof another Right
Certificate or Right Certificates for the number of whole Rights not exercised.

exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a share of Preferred Stock, which
may, at the election of the Company, be evidenced by depositary receipts), but
in lieu thereof a cash payment will be made, as provided in the Rights
Agreement.

          No holder of this Right Certificate, as such, shall be entitled to
vote or receive dividends or be deemed for any purpose the holder of the
Preferred Stock or of any other securities of the Company which may at any time

     UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS
     OWNED BY OR TRANSFERRED TO ANY PERSON WHO BECOMES AN ACQUIRING PERSON (AS
     DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN TRANSFEREES THEREOF WILL
     BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                            SUMMARY OF RIGHTS TO PURCHASE
                              Shares of Preferred Stock

          On November 16, 1995, the Board of Directors of Northwest Airlines
Corporation (the "Company") authorized and declared a dividend of one preferred
share purchase right (an "Original Right") for each outstanding share of Class A
Common Stock, par value $.01 per share, of the Company and Class B Common Stock,
par value $.01 per share, of the Company.  The dividend was paid to the
stockholders of record as of the close of business on November 27, 1995.  On
June 25, 1998 the Board of Directors amended the Original Rights in their
entirety to represent a right (a "Right") to purchase one one-hundredth of a
share of Series D Junior Participating Preferred Stock, par value $.01 per share
(the "Preferred Stock") of the Company at a price of $150 per one one-hundredth
of a share of Preferred Stock (as the same may be adjusted, the "Purchase
Price").  The description and terms of the Rights are set forth in an Amended
and Restated Rights Agreement dated as of June 25, 1998, as the same may be
amended from time to time (the "Rights Agreement"), between the Company 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 of a number of Common
Shares 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 sum of (a)
the Common Shares then issued and outstanding, (b) all Common Shares issuable
pursuant to the Northwest Airlines Employee Stock Plan (the "Plan") to trusts
established pursuant to the Plan (the "Trusts"), (c) all Common Shares issuable
upon conversion of all the shares of Series C Preferred Stock, par value $.01
per share, issued or issuable to the Trusts pursuant to the Plan, (d) all Common
Shares issuable upon the exercise of all employee stock options issued and
outstanding as of the date of this Agreement and (e) any other Common Shares not
then actually issued and outstanding but which such Person would be deemed to
beneficially own hereunder (together, the "outstanding Common Shares") or (ii)
10 business days (or such later date as may be determined by action of the Board
of Directors 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
Common Shares equal to 19% or more of the number of outstanding Common Shares
(the earlier of such dates being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate together
with a copy of the Summary of Rights.

          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 


                                         C-1
<PAGE>

Common Shares.  Until the Distribution Date (or earlier redemption or expiration
of the Rights), new Common Share certificates issued after the Record Date upon
transfer or new issuances of Common Shares (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 Shares outstanding as of the Record Date, even without such notation or a
copy of this Summary of Rights, will also constitute the transfer of the Rights
associated with the Common Shares 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 Shares 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 the Company, in each case as described below.

          The Purchase Price payable, and the number of shares of 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
Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-current market price of the Preferred Stock or (iii) upon the
distribution to holders of the Preferred Stock of evidences of indebtedness or
assets (excluding regular periodic cash dividends or dividends payable in
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 Shares or a stock dividend on the Common
Shares payable in Common Shares or subdivisions, consolidations or combinations
of the Common Shares occurring, in any such case, prior to the Distribution
Date.

          Shares of Preferred Stock purchasable upon exercise of the Rights 
will not be redeemable.  Each share of 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 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 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 Preferred Stock 

                                         C-2
<PAGE>

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 Common Shares (or one
one-hundredths of a share of 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, the Company 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 the Company has engaged in the foregoing transaction (or
its 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 Common Shares equal to 50% or more of the number of outstanding Common
Shares, the Board of Directors of the Company 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 Common Share, or one one-hundredth of a
share of Preferred Stock (or of a share of a class or series of the Company'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 Preferred Stock will be issued
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock, which may, at the election of the Company, be
evidenced by depositary receipts) and in lieu thereof, an adjustment in cash
will be made based on the market price of the 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 the Company 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, the Company may, except
with respect to the redemption price, amend the Rights in any manner.  After the
Rights are no 

                                         C-3
<PAGE>


longer redeemable the Company 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 the Company, including, without limitation, the right
to vote or to receive dividends.

          A copy of the Rights Agreement is available free of charge from the
Company.  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.
