Item 5.  Other Events.


     The form of Rights  Agreement  between  the  Company  and the Rights  Agent
specifying the terms of the Rights,  which includes as Exhibit  thereto the form
of Right Certificate, is attached hereto as Exhibit 4 and is incorporated herein
by  reference.  The foregoing  description  of the Rights does not purport to be
complete  and is  qualified  in its  entirety by reference to the form of Rights
Agreement (and the exhibits thereto) attached hereto.


     On October 27, 1998, the Board of Directors of Butler National  Corporation
(the  "Company")  declared a dividend of one preferred  share  purchase right (a
"Right") for each outstanding  share of Common Stock, par value $0.01 per share,
of the Company (the "Common  Stock").  The dividend  distribution  is payable on
October 27, 1998 (the "Record Date") to the stockholders of record on that date.
Each Right entitles the registered  holder to purchase from the Company  one-two
hundredth of a share of Series C Participating  Preferred Stock, par value $5.00
per share  (the  "Preferred  Stock")  of the  Company  at a price of $10.00  per
one-two hundredth of a share of Preferred Stock (the "Purchase Price"),  subject
to adjustment. The description and terms of the Rights are set forth in a Rights
Agreement  dated as of October 26, 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) the  close of  business  on the  tenth
business day following the date of public  announcement or the date on which the
Company first has notice or  determines  that a person or group of affiliated or
associated persons (other than the Company, any subsidiary of the Company or any
employee benefit plan of the Company) (an "Acquiring  Person") has acquired,  or
obtained the right to acquire,  15% or more of the outstanding  shares of voting
stock of the Company  without the prior express  written  consent of the Company
executed  on behalf of the Company by a duly  authorized  officer of the Company
following  express  approval  by action of at least a majority of the members of
the Board of Directors then in office (the "Stock Acquisition Date") or (ii) the
close of  business  on the  tenth  business  day (or such  later  date as may be
determined  by  action of the Board of  Directors  but not later  than the Stock
Acquisition  Date)  following  the  commencement  of a tender  offer or exchange
offer, without the prior written consent of the Company, by a person (other than
the Company,  any  subsidiary of the Company or an employee  benefit plan of the
Company) which, upon  consummation,  would result in such party's control of 15%
or more of the Company's voting stock (the earlier of the dates in clause (i) or
(ii) above being called the "Distribution  Date"), the Rights will be evidenced,
with  respect  to any of the Common  Stock  certificates  outstanding  as of the
Record Date, by such Common Stock certificates.


     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 Company's Common Stock.  Until the  Distribution  Date (or earlier
redemption, exchange or expiration of the Rights), new Common Stock certificates
issued after the Record Date upon transfer or new issuances of Common Stock will
contain a notation  incorporating  the Rights Agreement by reference.  Until the
Distribution Date (or earlier redemption, exchange or expiration of the Rights),
the  surrender  for  transfer  of any  certificates  for shares of Common  Stock
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 Stock  represented by such  certificate.  As soon as practicable
following the Distribution  Date,  separate  certificates  evidencing the Rights
("Right Certificates") will be mailed to holders of record of the Common Stock



<PAGE>

as of the  close  of  business  on  the  Distribution  Date  and  such  separate
certificates alone will then evidence the Rights.


     The Rights are not exercisable until the Distribution Date. The Rights will
expire,  if not  previously  exercised,  on the date  which is 10 years from the
Record Date (the "Final Expiration  Date"),  unless the Final Expiration Date is
extended or unless the Rights are earlier redeemed or exchanged by the Company.


     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 and the number of one-two hundredths of a
share of Preferred  Stock  issuable upon exercise of each Right are also subject
to  adjustment  in the  event of a stock  split of the  Common  Stock or a stock
dividend on the Common Stock payable in shares of Common Stock or  subdivisions,
consolidations or combinations of the Common Stock occurring,  in any such case,
prior to the Distribution Date.


     Shares of Preferred Stock  purchasable upon exercise of the Rights will not
be redeemable or convertible to any other series of preferred  stock the Company
may issue (unless otherwise provided in the terms of such stock).  Each share of
Preferred  Stock will have a  preferential  dividend  in an amount  equal to 200
times any  dividend  declared  on each  share of Common  Stock.  In the event of
liquidation,  the  holders  of the  Preferred  Stock  will  receive a  preferred
liquidation  payment of equal to the  greater  of $200 or 200 times the  payment
made per share of Common  Stock.  Each  share of  Preferred  Stock will have 200
votes,  voting  together  with the  Common  Stock.  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 200
times the amount and type of  consideration  received per share of Common Stock.
The rights of the Preferred Stock as to dividends,  liquidation and voting,  and
in  the  event  of  mergers  and  consolidations,  are  protected  by  customary
antidilution provisions.


     Because of the nature of the Preferred  Stock's  dividend,  liquidation and
voting  rights,  the  value  of the  one-two  hundredth  interest  in a share of
Preferred Stock  purchasable upon exercise of each Right should  approximate the
value of one share of Common Stock.


     If any person or group  (other  than the  Company,  any  subsidiary  of the
Company or any employee benefit plan of the Company) acquires 15% or more of the
Company's  outstanding  voting stock  without the prior  written  consent of the
Board of Directors, each Right, except those held by such persons, would entitle
each holder of a Right to acquire such number of shares of the Company's  Common
Stock as shall  equal  the  result  obtained  by  multiplying  the then  current
Purchase Price by the number of one-two hundredths of a share of Preferred Stock
for which a Right is then  exercisable  and dividing  that product by 50% of the
then current per-share market price of Company Common Stock.


     If any person or group  (other  than the  Company,  any  subsidiary  of the
Company or any employee benefit plan of the Company)  acquires more than 15% but
less than 50% of the  outstanding  Company  Common Stock  without  prior written
consent of the Board of Directors, each Right, except those held by such


                                       2
<PAGE>

persons,  may be exchanged  by the Board of  Directors  for one share of Company
Common Stock.


     If the  Company  were  acquired in a merger or other  business  combination
transaction where the Company is not the surviving  corporation or where Company
Common Stock is exchanged or changed or 50% or more of the  Company's  assets or
earnings power is sold in one or several  transactions without the prior written
consent of the Board of Directors,  each Right would entitle the holders thereof
(except  for the  Acquiring  Person)  to  receive  such  number of shares of the
acquiring  company's  common  stock as shall be equal to the result  obtained by
multiplying the then current Purchase Price by the number one-two  hundredths of
a share of Preferred  Stock for which a Right is then  exercisable  and dividing
that  product by 50% of the then  current  market  price per share of the common
stock of the  acquiring  company  on the date of such  merger or other  business
combination transaction.


     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-two  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 $.0025 per Right (the  "Redemption  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.
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.


     The terms of the Rights may be  amended  by the Board of  Directors  of the
Company  without the consent of the  holders of the Rights,  including,  but not
limited to, an amendment to lower certain thresholds described above to not less
than the greater of (i) any  percentage  greater than the largest  percentage of
the voting power of all  securities  of the Company then known to the Company to
be beneficially owned by any person or group of affiliated or associated persons
(other  than an excepted  person) and (ii) 10%,  except that from and after such
time as any  person or group of  affiliated  or  associated  persons  becomes an
Acquiring  Person no such  amendment may  adversely  affect the interests of the
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.

                                RIGHTS AGREEMENT


     This Rights Agreement, dated as of October 26, 1998 is entered into between
Butler National Corporation,  a Delaware corporation (the "Company") and Norwest
Bank Minnesota, N.A., a Minnesota corporation (the "Rights Agent").

                               W I T N E S S E T H


     WHEREAS,  on  October  26,  1998 the  Board  of  Directors  of the  Company
authorized  and  declared  a  dividend  distribution  of one right  (hereinafter
referred  to as a "Right")  for each share of Common  Stock,  par value $.01 per
share,  of the Company  outstanding at the close of business on October 26, 1998
(the  "Record  Date"),  (other  than  shares of such  Common  Stock  held in the
Company's treasury on such date) and has authorized the issuance of one Right in
respect of each share of Common Stock of the Company  issued  between the Record
Date (whether  originally issued or issued from the Company's  treasury) and the
Distribution  Date (as such term is defined  in  Section 3  hereof),  each Right
representing  the right to  purchase  one-two  hundredth  of a share of Series C
Participating  Preferred  Stock of the  Company  having the  rights,  powers and
preferences set forth in the form of Certificate of Designations attached hereto
as Exhibit A, upon the terms and subject to the conditions hereinafter set forth
(the "Rights"); and


     WHEREAS, the Company desires to appoint the Rights Agent to act as provided
herein, and the Rights Agent is willing to so act.


     NOW, THEREFORE,  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 Rights Agreement, the
following terms have the meanings indicated:


     (a) "Acquiring  Person" shall mean any Person (as hereinafter  defined) who
or which,  together with all Affiliates (as hereinafter  defined) and Associates
(as hereinafter  defined) of such Person,  without the Prior Written Approval of
the  Company  (as  hereinafter  defined),  shall  be the  Beneficial  Owner  (as
hereinafter  defined) of securities of the Company  constituting  15% or more of
the  Voting  Power  (as  hereinafter  defined)  of the  Company  or  was  such a
Beneficial  Owner at any time after the date hereof,  whether or not such Person
continues to be the Beneficial  Owner of securities  representing 15% or more of
the Voting  Power of the  Company,  but shall not include (i) the  Company,  any
Subsidiary of the Company, any employee benefit plan or compensation arrangement
of the  Company  or  any  Subsidiary  of the  Company,  or  any  entity  holding
securities of the Company to the extent  organized,  appointed or established by
the Company or any Subsidiary of the Company for or pursuant to the terms of any
such employee benefit plan or compensation arrangement or (ii) any Person who or
which, together with all Affiliates and Associates of such Person, inadvertently
may become the Beneficial Owner of securities of the Company representing 15% or
more of the Voting Power of the Company or  otherwise  becomes such a Beneficial
Owner without a plan or intention to acquire control of the Company,  so long as
such Person, individually or together with the Affiliates and Associates of such
Person,  promptly  enters  into,  and delivers to the  Company,  an  irrevocable
commitment   promptly  to  divest,  and  thereafter  promptly  divests  (without
exercising  or  retaining  any power,  including  voting,  with  respect to such
securities),  sufficient securities of the Company so that such Person, together
with all Affiliates  and Associates of such Person,  ceases to be the Beneficial
Owner of 15% or more of the Voting  Power of the  Company.  Notwithstanding  the
foregoing, no Person shall become an "Acquiring Person" as the result of an

<PAGE>

acquisition  of voting  securities  of the  Company  by the  Company  which,  by
reducing the amount of such securities outstanding,  increases the proportionate
voting power of such securities beneficially owned by such Person to 15% or more
of the Voting Power of the Company; provided,  however, that if a Person becomes
the Beneficial Owner of securities  constituting 15% or more of the Voting Power
of the  Company by reason of  purchases  by the  Company  and shall,  after such
purchases by the Company,  become the Beneficial Owner of any additional  voting
securities  of the Company  without the Prior  Written  Approval of the Company,

     proxy or consent solicitation made pursuant to, and in accordance with, the
     applicable rules and regulations under the Exchange Act and (2) is not also
     then  reportable  by such person on Schedule 13D under the Exchange Act (or
     any comparable or successor report); or


          (iii) which are  beneficially  owned,  directly or indirectly,  by any
     other Person with which such Person or any of such  Person's  Affiliates or
     Associates has any  agreement,  arrangement  or  understanding  (other than
     customary  agreements  with and  between  underwriters  and  selling  group
     members with respect to a bona fide public  offering of securities) for the

without the Prior  Written  Approval of the  Company,  which  tender or exchange

which is after the date of this Rights  Agreement  and prior to the  issuance of

send, by  first-class,  insured,  postage prepaid mail, to each record holder of
the Common Stock as of the close of business on the  Distribution  Date,  at the
address of such holder shown on the records of the Company, a right certificate,
in  substantially  the form of  Exhibit  B  hereto  (the  "Right  Certificate"),
evidencing  one  Right  for each  share of  Common  Stock  so held,  subject  to
adjustment as provided herein. As of and after the Distribution Date, the Rights
will be evidenced solely by such Right Certificates.


                                       4
<PAGE>

     (b) On the Record Date or as soon as  practicable  thereafter,  the Company
will  send a copy of a  Summary  of  Rights  to  Purchase  Preferred  Stock,  in
substantially  the form of  Exhibit  C hereto  (the  "Summary  of  Rights"),  by
first-class,  postage prepaid mail, to each record holder of the Common Stock as
of the close of business on the Record Date, at the address of such holder shown
on the records of the Company. With respect to certificates for the Common Stock
outstanding as of the Record Date, until the  Distribution  Date (or the earlier
redemption,  expiration  or  termination  of the  Rights),  the  Rights  will be
evidenced by such  certificates  for the Common Stock registered in the names of
the holders of the Common Stock and the  registered  holders of the Common Stock
shall  also  be  registered  holders  of  the  associated   Rights.   Until  the
Distribution Date (or the earlier  redemption,  expiration or termination of the
Rights),  the surrender for transfer of any of the  certificates  for the Common
Stock  outstanding  in  respect  of which  Rights  have been  issued  shall also
constitute  the  transfer  of  the  Rights  associated  with  the  Common  Stock
represented by such certificate.


     (c)  Certificates  for the Common  Stock  issued  after the Record Date but
prior to the earlier of the Distribution  Date or the redemption,  expiration or
termination of the Rights shall be deemed also to be certificates for Rights and
shall have  impressed,  printed or written  on, or  otherwise  affixed to them a
legend substantially to the following effect:


     This  certificate  also evidences and entitles the holder hereof to certain
     Rights as set forth in a Rights  Agreement  dated as of  October  26,  1998
     between  Butler  National  Corporation  (the  "Company")  and Norwest  Bank
     Minnesota,  N.A.  (the  "Rights  Agent"),  as it may  from  time to time be
     supplemented  or  amended,  the terms of which are  incorporated  herein by
     reference and a copy of which is on file at the principal executive offices
     of the Company.  Under  certain  circumstances,  as set forth in the Rights
     Agreement,  such  Rights may  expire or may be  redeemed,  exchanged  or be
     evidenced  by  separate  certificates  and no longer be  evidenced  by this
     certificate. The Company will mail to the holder of this certificate a copy
     of the Rights Agreement  without charge promptly after receipt of a written
     request therefor. Under certain circumstances,  Rights issued to or held by
     Acquiring  Persons or their  Affiliates  or  Associates  (as defined in the
     Rights  Agreement) and any subsequent holder of such Rights may become null
     and void.


With respect to such  certificates  containing the foregoing  legend,  until the
Distribution Date (or the earlier  redemption,  expiration or termination of the
Rights),  the  Rights  associated  with the  Common  Stock  represented  by such
certificates  shall be evidenced by such  certificates  alone, and the surrender
for transfer of any of such  certificates  shall also constitute the transfer of
the Rights associated with the Common Stock represented by such certificates.


     In the event that the Company  purchases or acquires any Common Stock after
the Record Date but prior to the Distribution  Date, any Rights  associated with
such Common Stock shall be deemed canceled and retired so that the Company shall
not be entitled to exercise  any Rights  associated  with shares of Common Stock
which are no longer outstanding.


     Section 4. Form of Right Certificates.


     (a) The Right  Certificates  (and the forms of election to purchase  shares
and  of  assignment  to  be  printed  on  the  reverse   thereof)  shall  be  in
substantially  the same  form as  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 Rights  Agreement,  or as may be required to comply
with any  applicable  law,  rule or regulation or with any rule or regulation of
any stock exchange on which the Rights may from time to time be listed, or to


                                       5
<PAGE>

conform to customary usage.  Subject to the provisions of Section 11 and Section
22 hereof,  the Right  Certificates,  whenever issued,  shall be dated as of the
Record  Date,  and on their face shall  entitle the holders  thereof to purchase
such number of one-two  hundredths of a share of Preferred Stock as shall be set
forth therein at the price per one-two hundredth of a share as set forth therein
(the  "Purchase  Price"),  but the number and  identity  of such  shares and the
Purchase Price shall be and remain subject to adjustment as provided in Sections
11, 13 and 22 hereof.


     (b) Any Right  Certificate  issued pursuant  hereto that represents  Rights
beneficially  owned by (i) an Acquiring  Person or any Associate or Affiliate of
an Acquiring  Person,  (ii) a transferee of an Acquiring  Person (or of any such
Associate or Affiliate)  which becomes a transferee  after the Acquiring  Person
becomes  such,  or (iii) a  transferee  of an  Acquiring  Person (or of any such
Associate or Affiliate) which becomes a transferee prior to or concurrently with
the Acquiring  Person  becoming such and which receives such Rights  pursuant to
either (A) a transfer  (whether  or not for  consideration)  from the  Acquiring
Person (or any such  Associate or Affiliate)  to holders of equity  interests in
such  Acquiring  Person (or such  Associate or  Affiliate) or to any Person with
whom such  Acquiring  Person (or such Associate or Affiliate) has any continuing
agreement, arrangement or understanding regarding either the transferred Rights,
shares of Company Common Stock or the Company or (B) a transfer which a majority
of the Board of Directors has  determined to be part of a plan,  arrangement  or
understanding  which has as a primary purpose or effect the avoidance of Section
7(e), and any Right Certificate issued pursuant to Section 6 hereof,  Section 11
hereof or Section 22 hereof upon transfer,  exchange,  replacement or adjustment
of any other Right Certificate  referred to in this sentence,  shall contain (to
the extent feasible) the following legend:


     The Rights  represented by this Right  Certificate are or were beneficially
     owned by a Person who was or became an Acquiring  Person or an Affiliate or
     an Associate of an Acquiring  Person.  Accordingly,  this Right Certificate
     and the Rights represented  hereby are void in the circumstances  specified
     in Section 7(e) of the Rights Agreement.


     The failure to print the foregoing legend on any such Right  Certificate or
any defect therein shall not affect in any manner  whatsoever the application or
interpretation of the provisions of Section 7(e) hereof.


     Section 5. Countersignature and Registration.


     (a) The Right  Certificates  shall be  executed on behalf of the Company by
its Chairman of the Board, Chief Executive Officer,  President,  Chief Financial
Officer or any Vice President,  either manually or by facsimile  signature,  and
shall have affixed thereto the Company's seal or a facsimile thereof which shall
be attested by the  Secretary or an Assistant  Secretary of the Company,  either
manually  or  by  facsimile   signature.   The  Right   Certificates   shall  be
countersigned  manually or by  facsimile  signature  by the Rights  Agent or the
registrar or co-registrar  for the Common Stock (the  "Registrar") and shall not
be valid for any  purpose  unless so  countersigned.  In case any officer of the
Company whose manual or facsimile signature is affixed to the Right Certificates
shall cease to be such  officer of the Company  before  countersignature  by the
Rights Agent or the  Registrar  and  issuance and delivery by the Company,  such
Right  Certificates,  nevertheless,  may be countersigned by the Rights Agent or
the Registrar, issued and delivered 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. 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 Certificate, shall
be a proper officer of the Company to sign such Right Certificate, although at


                                       6
<PAGE>


the date of the execution of this Rights  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 its stockholder  services office or such other office 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,  the certificate  number of 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 Section 14 hereof,  at any time after the
close of  business  on the  Distribution  Date,  and at or prior to the close of
business  on the  Expiration  Date (as such  term is  defined  in  Section  7(a)
hereof),  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 shares 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  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
stockholder  services  office of the Rights Agent or such office  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 that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.


     (b) 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 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  countersignature  and delivery to the  registered
owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.


     Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights.


     (a) The registered  holder of any Right Certificate may exercise the Rights
evidenced  thereby (except as otherwise  provided herein) in whole or in part at
any time after the  Distribution  Date 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  stockholder  services  office of the Rights Agent or
such office  designated for such purpose,  together with payment of the Purchase
Price for each one-two  hundredth of a share of Preferred  Stock as to which the
Rights are  exercised,  at or prior to the close of business  on the  Expiration
Date. The  "Expiration  Date",  as used in this Rights  Agreement,  shall be the
earliest of (i) the Final  Expiration Date (as defined below),  (ii) the time at
which the Rights are  redeemed as  provided  in Section 23 hereof,  or (iii) the
time at which the Rights are  exchanged  as provided  in Section 24 hereof.  The
"Final  Expiration  Date", as used in this Rights  Agreement,  shall be the date
which is 10 years from the Record Date.

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

     (c) Upon  receipt  of a Right  Certificate,  with the form of  election  to
purchase duly  executed,  accompanied  by payment of the Purchase Price for each
one-two  hundredth of a share of Preferred  Stock to be purchased  and an amount
equal to any  applicable  transfer  tax required to be paid by the holder of the
Rights pursuant  hereto in accordance with Section 9 hereof by certified  check,
cashier's check or money order payable to the order of the Company or the Rights
Agent,  the Rights  Agent  shall,  subject to Section  20(k)  hereof,  thereupon
promptly (i) either (A)  requisition  from any  transfer  agent of the shares of
Preferred Stock (or make  available,  if the Rights Agent is the transfer agent)
certificates for the number of shares of Preferred Stock to be purchased and the
Company hereby irrevocably authorizes any such transfer agent to comply with all
such requests, or (B) if the Company, in its sole discretion, shall have elected
to deposit the shares of Preferred  Stock  issuable  upon exercise of the Rights
hereunder into a depositary,  requisition  from the depositary  agent depositary
receipts  representing such number of one-two hundredths of a share of Preferred
Stock as are to be  purchased  (in which  case  certificates  for the  shares of
Preferred Stock  represented by such receipts shall be deposited by the transfer
agent with the depositary  agent) and the Company hereby directs such depositary
agent to comply with all such  requests,  (ii)  promptly  after  receipt of such
certificates  or depositary  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,  (iii)  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 hereof, (iv) after receipt of
any such cash, promptly deliver such cash to or upon the order of the registered
holder of such Right  Certificate,  (v) when  appropriate,  requisition from the
Company  the amount of cash or  securities  issuable  upon  exercise  of a Right
pursuant to the adjustment  provisions of Section 11 or the exchange  provisions
of Section 24, and (vi) after receipt of any such cash or  securities,  promptly
deliver such cash or securities to or upon the order of the registered holder of
such Right Certificate, of any such cash or securities.


     (d) In case the registered  holder of any Right  Certificate shall exercise
less than all the Rights evidenced thereby,  a new Right Certificate  evidencing
Rights  equivalent to the Rights  remaining  unexercised  shall be issued by the
Rights  Agent to the  registered  holder of such  Right  Certificate  or to such
holder's  duly  authorized  assigns,  subject  to the  provisions  of Section 14
hereof.


     (e) Notwithstanding anything in this Rights Agreement to the contrary, upon
the first  occurrence of a Section 11(b) Event or a Section 13 Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring  Person,  (ii) a  transferee  of an  Acquiring  Person (or of any such
Associate or Affiliate)  which becomes a transferee  after the Acquiring  Person
becomes  such,  or (iii) a  transferee  of an  Acquiring  Person (or of any such
Associate or Affiliate) which becomes a transferee prior to or concurrently with
the Acquiring  Person  becoming such and which receives such Rights  pursuant to
either (A) a transfer  (whether  or not for  consideration)  from the  Acquiring
Person (or any such  Associate or Affiliate)  to holders of equity  interests in
such Acquiring Person (or any such Associate or Affiliate) or to any Person with
whom such  Acquiring  Person (or such Associate or Affiliate) has any continuing
agreement, arrangement or understanding regarding the transferred Rights, shares
of Company Common Stock or the Company or (B) a transfer which a majority of the
Board  of  Directors  has  determined  to be  part  of a  plan,  arrangement  or
understanding  which has as a primary  purpose or effect the  avoidance  of this
Section 7(e),  shall be null and void without any further action,  and no holder
of such Rights shall have any rights whatsoever with respect to such Rights,


                                       8
<PAGE>

whether  under any provision of this  Agreement or otherwise.  The Company shall
use all  reasonable  efforts to ensure that the  provisions of this Section 7(e)
and Section 4(b) are complied with, but shall have no liability to any holder of
Rights or any other Person as a result of its failure to make any  determination
under this Section  7(e) or Section 4(b) with respect to an Acquiring  Person or
its Affiliates, Associates or transferees hereunder.


     (f)  Notwithstanding  anything in this Rights  Agreement  to the  contrary,
neither the Rights Agent nor the Company  shall be  obligated  to undertake  any
action with respect to a registered  holder upon the occurrence of any purported
exercise as set forth in this Section 7 unless the certificate  contained in the
appropriate  form of election to purchase  set forth on the reverse  side of the
Right  Certificate  surrendered  for such  exercise  shall  have  been  properly
completed and duly  executed by the  registered  holder  thereof and the Company
shall have been  provided with such  additional  evidence of the identity of the
Beneficial  Owner (or  former  Beneficial  Owner) or  Affiliates  or  Associates
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 canceled form,
or, if  surrendered  to the Rights Agent,  shall be canceled by it, and no Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Rights 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 canceled Right  Certificates to the Company  approximately  one and one half
years after the cancellation date.


     Section 9. Reservation and 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
its  authorized and issued 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  and,  after the  occurrence  of a
Section 11(b) Event or a Section 13 Event, shall so reserve and keep available a
sufficient  number of shares of  Preferred  Stock,  Common  Stock  and/or  other
securities  which may be required  to permit the  exercise in full of the Rights
pursuant to this Rights Agreement.


     (b) 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/or  other
securities  delivered upon exercise of Rights shall,  at the time of delivery of
the certificates for such shares or other securities  (subject to payment of the
Purchase  Price),  be duly and validly  authorized and issued and fully paid and
nonassessable shares or securities.


     (c) The  Company  shall  use  its  best  efforts  to (i)  file,  as soon as
practicable following the first occurrence of an event which would establish the
Distribution Date, a registration statement under the Securities Act of 1933, as
amended (the "Securities Act"), with respect to the securities  purchasable upon
exercise  of the Rights on an  appropriate  form,  (ii) cause such  registration
statement to become  effective  as soon as  practicable  after such filing,  and
(iii) cause such  registration  statement to remain effective (with a prospectus
at  all  times  meeting  the  requirements  of the  Securities  Act)  until  the
Expiration  Date.  The Company will also take such action as may be  appropriate
under the "blue sky laws" of the various states.


     (d) 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


                                       9
<PAGE>

any shares of  Preferred  Stock  and/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  involved  in the  transfer  or
delivery of Right  Certificates  or the issuance or delivery of  certificates or
depositary  receipts for Preferred Stock and/or other securities in a name other
than that of the registered  holder of the Right  Certificate  evidencing Rights
surrendered for exercise,  nor shall the Company be required to issue or deliver
any  certificates  or depositary  receipts for shares of Preferred  Stock and/or
other  securities  upon the exercise of any Rights until any such tax shall have
been paid (any such tax being payable by the holder of such Right Certificate at
the  time of  surrender)  or  until it has  been  established  to the  Company's
satisfaction that no such tax is due.


     Section 10.  Preferred  Stock  Record  Date.  Each  person  (other than the
Company) in whose name any  certificate  for shares of Preferred Stock (or other
securities)  is issued  upon the  exercise of Rights  shall for all  purposes be
deemed to have  become  the  holder of record of the  Preferred  Stock (or other
securities)  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 (or other securities)  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  (or other  securities)
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 stockholder  of the Company with respect to shares for which the
Rights shall be exercisable,  including,  without limitation, the right to vote,
to receive  dividends  or other  distributions  or to  exercise  any  preemptive
rights,  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 or Number of
Rights.  The Purchase  Price,  the number and identity of shares covered by each
Right and the number of Rights  outstanding  are subject to adjustment from time
to time as provided in this Section 11.


     (a) In the  event  the  Company  shall at any time  after  the date of this
Rights Agreement (i) declare a dividend on the Preferred Stock payable in shares
of Preferred  Stock,  (ii)  subdivide the  outstanding  Preferred  Stock,  (iii)
combine the outstanding  Preferred Stock into a smaller number of shares or (iv)
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, the Purchase  Price in effect at the
time of the record date for such dividend or the time of the  effective  date of
such subdivision,  combination or  reclassification,  and the number and kind of
shares of capital stock,  including Preferred Stock, issuable upon exercise of a
Right,  shall be  proportionately  adjusted  so that  the  holder  of any  Right
exercised  after such time,  upon payment of the  aggregate  consideration  such
holder would have had to pay to exercise such Right prior to such time, shall be
entitled to receive the  aggregate  number and kind of shares of capital  stock,
including Preferred 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,  such holder  would have owned upon such  exercise  and been
entitled  to receive by virtue of such  dividend,  subdivision,  combination  or
reclassification.


     (b) In the event any Person  becomes an Acquiring  Person  ("Section  11(b)
Event"),  then  proper  provision  shall be made so that each holder of a Right,
subject to Section  7(e) and  Section  24 hereof and except as  provided  below,
shall after the later of the  occurrence of such event and the effective date of
an appropriate registration statement pursuant to Section 9 hereof, have a right


                                       10
<PAGE>

to receive, upon exercise thereof at the then current Purchase Price, multiplied
by the then number of one-two hundredths of a share of Preferred Stock for which
a Right  is then  exercisable,  in  accordance  with the  terms  of this  Rights
Agreement, in lieu of shares of Preferred Stock, such number of shares of Common
Stock of the Company as shall equal the result  obtained by (y)  multiplying the
then current Purchase Price by the then number of one-two  hundredths of a share
of  Preferred  Stock for which a Right is then  exercisable  and  dividing  that
product by (z) 50% of the  current  market  price per one share of Common  Stock
(determined  pursuant to Section  11(f) hereof on the date of the  occurrence of
the Section 11(b) Event) (such number of shares being referred to as the "number
of Adjustment Shares").


     (c) In the event  that there  shall not be  sufficient  Treasury  shares or
authorized but unissued shares of Common Stock to permit the exercise in full of
the Rights in accordance with the foregoing Section 11(b), and the Rights become
so exercisable, notwithstanding any other provision of this Rights Agreement, to
the extent  necessary  and  permitted by  applicable  law and any  agreements in
effect on the date  hereof to which the  Company is a party,  each  Right  shall
thereafter  represent the right to receive,  upon  exercise  thereof at the then
current Purchase Price, multiplied by the then number of one-two hundredths of a
share of Preferred  Stock for which a Right is then  exercisable,  in accordance
with the terms of this Rights Agreement, a number of shares, or units of shares,
of (y) Common Stock, and (z) preferred stock (or other equity securities) of the
Company,  including,  but not limited to Preferred Stock, equal in the aggregate
to the number of  Adjustment  Shares where the Board of Directors  shall have in
good faith deemed such shares or units,  other than the shares of Common  Stock,
to have at least the same value and voting rights as the Common Stock (a "common
stock  equivalent");  provided,  however,  if there are  unavailable  sufficient
shares (or fractions of shares) of Common Stock and/or common stock equivalents,
then the Company  shall take all such action as may be  necessary  to  authorize
additional  shares of Common Stock or common stock equivalents for issuance upon
exercise of the Rights, including the calling of a meeting of stockholders;  and
provided,  further,  that if the Company is unable to cause sufficient shares of
Common Stock and/or common stock  equivalents  to be available for issuance upon
exercise in full of the Rights,  then the Company,  to the extent  necessary and
permitted by applicable  law and any  agreements or instruments in effect on the
date  thereof to which it is a party,  shall make  provision to pay an amount in
cash equal to twice the  Purchase  Price (as  adjusted  pursuant to this Section
11), in lieu of issuing shares of Common Stock and/or common stock  equivalents.
To the extent that the  Company  determines  that some action  needs to be taken
pursuant to this Section  11(c),  the Board of Directors by action of at least a
majority of its members  then in office may  suspend the  exercisability  of the
Rights  for a period of up to sixty  (60) days  following  the date on which the
Section 11(b) Event shall have occurred, in order to decide the appropriate form
of  distribution  to be made pursuant to this Section 11(c) 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. The Board of Directors may, but shall not be required to,
establish  procedures  to allocate the right to receive  Common Stock and common
stock  equivalents  upon exercise of the Rights among  holders of Rights,  which
such allocation may be, but is not required to be, pro-rata.


     (d) If the Company  shall fix a record  date for the  issuance of rights or
warrants to all holders of Preferred Stock entitling them (for a period expiring
within 90 calendar  days after such record  date) to  subscribe  for or purchase
Preferred  Stock  (or  securities  having  the  same or more  favorable  rights,
privileges  and  preferences  as  the  Preferred  Stock  ("equivalent  preferred
stock")) or securities  convertible into Preferred Stock or equivalent preferred
stock,  at a price  per  share of  Preferred  Stock or per  share of  equivalent
preferred  stock or having a conversion or exercise price per share, as the case
may be,  less than the current  market  price per share of  Preferred  Stock (as
defined in Section 11(f) hereof) on such record date,  the Purchase  Price to be
in effect after such record date shall be determined by multiplying the Purchase


                                       11
<PAGE>

Price in effect  immediately prior to such date by a fraction,  the numerator of
which  shall be the  number of shares of  Preferred  Stock  outstanding  on such
record date plus the number of shares of  Preferred  Stock  which the  aggregate
offering  price of the total number of shares of Preferred  Stock or  equivalent
preferred stock 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  outstanding  on such record date plus the number of additional
shares of Preferred  Stock and/or  equivalent  preferred stock to be offered for
subscription  or purchase  (or into which the  convertible  securities  so to be
offered are initially convertible).  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 a majority
of the Board of Directors, whose determination shall be described in a statement
filed with the Rights Agent.  Shares of Preferred Stock 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 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.


     (e) If the Company shall fix a record date for the making of a distribution
to all holders of  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,  cash (other than a
regular  periodic  cash  dividend  out of earnings  or retained  earnings of the
Company),  assets  (other  than a  dividend  payable  in  Preferred  Stock,  but
including  any  dividend  payable  in  stock  other  than  Preferred  Stock)  or
convertible  securities,   subscription  rights  or  warrants  (excluding  those
referred to in Section 11(d)  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 which
shall be the current  market price for one share of Preferred  Stock (as defined
in Section  11(f)  hereof) on such record  date less the fair  market  value (as
determined  in good  faith  by a  majority  of the  Board  of  Directors,  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 convertible  securities,  subscription  rights or warrants applicable to
one share of Preferred Stock, and the denominator of which shall be such current
market price for one share of Preferred Stock.  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.


     (f) (i) For the purpose of any computation  hereunder,  the "current market
price" of any security (a "Security"  for purposes of this Section  11(f)(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  hereinafter  defined)
immediately prior to such date;  provided,  however,  that in the event that the
current  market price per share of such 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 shares of such Security or (B) any 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 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


                                       12
<PAGE>

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 New York Stock  Exchange  or, if the  Security  is not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated  transaction  reporting system with respect to securities listed or
admitted to trading 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,  as reported by the
National  Association of Securities  Dealers,  Inc.  Automated  Quotation System
("Nasdaq")  National Market System, or if the Security is not listed or admitted
to  trading  on any  national  securities  exchange  or  included  in the Nasdaq
National Market System,  the average of the high bid and low asked prices in the
over-the-counter market, as reported by Nasdaq or such other system then in use,
or, if on any such date the Security is not quoted by any such organization, the
average of the  closing  bid and asked  prices as  furnished  by a  professional
market maker making a market in the Security selected by a majority of the Board
of  Directors.  If on any such  date no  market  maker is making a market in the
Security,  the fair value of such  Security on such date as  determined  in good
faith by a majority of the Board of Directors  shall be used.  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 day on which the Nasdaq National Market System is
open for the  transaction  of  business  or, if the  Security  is not  listed or
admitted  to trading on any  national  securities  exchange  or  included in the
Nasdaq National  Market System,  a Business Day. If the Security is not publicly
held or not so listed or  traded,  "current  market  price"  shall mean the fair
value as determined in good faith by a majority of the Board of Directors, whose
determination shall be described in a statement filed with the Rights Agent.


          (ii) For the purpose of any computation hereunder, the "current market
     price" per share (or one-two hundredth of a share) of Preferred Stock shall
     be determined in the same manner as set forth above for the Common Stock in
     clause (i) of this Section 11(f) (other than the last sentence thereof). If
     the current  market  price per share (or one-two  hundredth  of a share) of
     Preferred Stock cannot be determined in the manner provided above or if the
     Preferred  Stock is not  publicly  held or  listed  or  traded  in a manner
     described in clause (i) of this Section 11(f),  the "current  market price"
     per share of Preferred Stock shall be  conclusively  deemed to be an amount
     equal to 100 (as such number may be appropriately  adjusted for such events
     as stock splits, stock dividends and recapitalizations  with respect to the
     Common Stock occurring after the date of this Rights Agreement)  multiplied
     by the current  market price per share of the Common Stock and the "current
     market price" per one-two  hundredth of a share of Preferred Stock shall be
     equal to the  current  market  price  per  share of the  Common  Stock  (as
     appropriately  adjusted).  If neither  the Common  Stock nor the  Preferred
     Stock is publicly held or so listed or traded,  "current  market price" per
     share  shall mean the fair value per share as  determined  in good faith by
     the  Board  of  Directors,  whose  determination  shall be  described  in a
     statement  filed  with the  Rights  Agent and shall be  conclusive  for all
     purposes.


     (g) 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(g) 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  ten-thousandth  of a share,
as the case may be. Notwithstanding the first sentence of this Section 11(g),


                                       13
<PAGE>

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 mandates such
adjustment or (ii) the Expiration Date.


     (h) In the  event  that at any  time,  as a result  of an  adjustment  made
pursuant  to  Section  11(a) or (b)  hereof,  the  holder of any Right  shall be
entitled to receive upon  exercise of such Right any shares of capital  stock of
the Company other than shares of Preferred Stock,  thereafter the number of such
other  shares so  receivable  upon  exercise  of any 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 shares  contained in Section
11(a) through (e) hereof, inclusive, and the provisions of Sections 7, 9, 10, 13
and 14 hereof with respect to the shares of Preferred  Stock shall apply on like
terms to any such other shares.


     (i)  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-two hundredths of a
share of Preferred Stock or other capital stock of the Company  purchasable from
time to time  hereunder  upon  exercise  of the  Rights,  all subject to further
adjustment of the Purchase Price.


     (j) Unless the Company  shall have  exercised  its  election as provided in
Section 11(k) hereof,  upon each adjustment of the Purchase Price as a result of
the calculations  made in Section 11(d) and (e) hereof,  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-two
hundredths  of  a  share  of  Preferred   Stock   (calculated   to  the  nearest
ten-thousandth) obtained by (i) multiplying (A) the number of one-two hundredths
of a share  of  Preferred  Stock  covered  by a Right  immediately  prior to the
adjustment  by (B) the  Purchase  Price  in  effect  immediately  prior  to such
adjustment  of the Purchase  Price and (ii)  dividing the product so obtained by
the Purchase Price in effect  immediately  after such adjustment of the Purchase
Price.


     (k) 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 shares 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-two  hundredths of a
share of Preferred Stock for which such 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
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(k),  the Company  shall,  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 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 may bear, at the option


                                       14
<PAGE>

of the Company,  the adjusted  Purchase  Price) and shall be  registered  in the
names  of the  holders  of  record  of Right  Certificates  on the  record  date
specified in the public announcement.


     (l)  Irrespective  of any adjustment or change in the Purchase Price or the
number of shares 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 shares which were expressed in the initial
Right Certificates issued hereunder.


     (m) Before  taking any action that would cause an  adjustment  reducing the
Purchase  Price below the then par value,  if any, of the shares of Common Stock
or other  securities and below one-two  hundredth of the then par value, if any,
of the Preferred 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 such Preferred Stock,  Common Stock or other securities
at such adjusted Purchase Price. If upon any exercise of the Rights, a holder is
to receive a combination of Common Stock and common stock equivalents, a portion
of the  consideration  paid upon such  exercise,  equal to at least the then par
value of a share of  Common  Stock of the  Company,  shall be  allocated  as the
payment for each share of Common Stock of the Company so received.


     (n) 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 the shares
of Preferred Stock and other capital stock or securities of the Company, if any,
issuable  upon such  exercise  over and above the shares of 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.


     (o)  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 in their  good  faith  judgment  a  majority  of the  Board of
Directors shall determine to be advisable in order that any (i) consolidation or
subdivision  of the  Preferred  Stock,  (ii)  issuance  wholly  for  cash of any
Preferred  Stock at less than the then  current  market  price,  (iii)  issuance
wholly  for cash of  Preferred  Stock or  securities  which by their  terms  are
convertible into or exchangeable  for Preferred  Stock,  (iv) stock dividends or
(v)  issuance of rights,  options or warrants  referred to  hereinabove  in this
Section 11, hereafter made by the Company to the holders of its Preferred Stock,
shall not be taxable to such stockholders.


     (p) In the event that at any time after the date of this  Rights  Agreement
and prior to the  Distribution  Date,  the Company  shall (i) declare or pay any
dividend on the Common Stock  payable in shares of Common Stock or (ii) effect a
subdivision,   combination   or   consolidation   of  the   Common   Stock   (by
reclassification  or otherwise  than by payment of dividends in shares of Common
Stock) into a greater or lesser  number of shares of Common  Stock,  then in any
such case (y) the number of one-two  hundredths  of a share of  Preferred  Stock
purchasable  after such  event  upon  proper  exercise  of each  Right  shall be
determined  by  multiplying  the  number  of  one-two  hundredths  of a share of
Preferred  Stock so purchasable  immediately  prior to such event by a fraction,
the  numerator  of which is the  number of shares  of Common  Stock  outstanding
immediately  before  such  event and the  denominator  of which is the number of
shares of Common Stock outstanding immediately after such event, and (z) each


                                       15

share of Common Stock outstanding immediately after such event shall have issued
with  respect  to it that  number of Rights  which  each  share of Common  Stock
outstanding  immediately  prior to such event had issued with respect to it. The
adjustments  provided  for in this  Section  11(p)  shall  be made  successively
whenever such a dividend is declared or paid or such a subdivision,  combination
or consolidation is effected.


     (q) The Company  covenants  and agrees that it shall not, at any time after
the Distribution  Date and so long as the Rights have not been redeemed pursuant
to Section 23 hereof or exchanged pursuant to Section 24 hereof, (i) consolidate
with,  (ii)  merge  with or into,  or  (iii)  sell or  transfer,  in one or more
transactions, assets or earning power aggregating more than 50% of the assets or
earning  power of the  Company and its  Subsidiaries  (taken as a whole) to, any
other Person, if at the time of or immediately after such consolidation,  merger
or sale  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.


     (r) The Company  covenants  and agrees  that,  after the Stock  Acquisition
Date,  it will not,  except as permitted by Sections 23 and 24 hereof,  take any
action the purpose or effect of which is to diminish  substantially or otherwise
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 Sections 11 or 13 hereof,  the
Company shall (a) promptly prepare a certificate  setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment,  (b) promptly
file with the Rights Agent and with each transfer agent for the Preferred  Stock
and the Common Stock a copy of such  certificate and (c) include a brief summary
thereof in a mailing to each holder of a Right  Certificate  in accordance  with
Section 26 hereof, or prior to the Distribution  Date,  disclose a brief summary
in a filing under the Exchange Act. The Rights Agent shall be fully protected in
relying on any such certificate and on any adjustments therein contained.


     Section 13. Consolidation,  Merger or Sale or Transfer of Assets or Earning
Power.


     (a) In the event that,  directly or indirectly,  at any time after a Person
has become an Acquiring Person, (x) the Company shall consolidate with, or merge
with and into, any other Person,  (y) any Person shall consolidate with or 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  Stock  shall  be  changed  into or  exchanged  for  stock  or other
securities  of any other Person (or the Company) or cash or any other  property,
or (z) 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 to the Company or one or more of its wholly-owned  Subsidiaries,  then, and
in each such case,  proper  provision shall be made so that (i) each holder of a
Right,  subject to  Section  7(e)  hereof,  shall  thereafter  have the right to
receive, upon the exercise thereof at the then current Purchase Price multiplied
by the then number of one-two hundredths of a share of Preferred Stock for which
a Right is then  exercisable  (or if a Section 11(b) Event has occurred prior to
the first  occurrence  of a Section  13 Event,  multiplying  the  number of such
one-two  hundredths  of a share for which a Right  was  exercisable  immediately
prior to the first  occurrence of a Section 11(b) Event by the Purchase Price in
effect  immediately prior to such first occurrence) in accordance with the terms
of this Rights  Agreement,  in lieu of Preferred Stock, such number of shares of
freely tradable Common Stock of the Principal Party (as hereinafter defined),


                                       16
<PAGE>

free and clear of liens, rights of call or first refusal,  encumbrances or other
adverse claims,  as shall be equal to the result obtained by (A) multiplying the
then current  Purchase  Price by the number of one-two  hundredths of a share of
Preferred  Stock for which a Right is then  exercisable  (or if a Section  11(b)
Event  has  occurred  prior to the  first  occurrence  of a  Section  13  Event,
multiplying  the number of such one-two  hundredths of a share for which a Right
was  exercisable  immediately  prior to the first  occurrence of a Section 11(b)
Event  by  the  Purchase  Price  in  effect  immediately  prior  to  such  first
occurrence),  and dividing  that product by (B) 50% of the current  market price
per share of the Common Stock of such Principal Party  (determined in the manner
described  in  Section  11(f)  hereof)  on the  date  of  consummation  of  such
consolidation,  merger,  sale  or  transfer;  (ii)  the  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 Rights Agreement; (iii) the term "Company" shall thereafter be deemed to
refer  to  such  Principal  Party,  it  being  specifically  intended  that  the
provisions of Section 11 hereof, except for the provisions of 11(b), shall apply
to such Principal  Party;  and (iv) such  Principal  Party shall take such steps
(including,  but  not  limited  to,  the  authorization  and  reservation  of  a
sufficient  number of  shares of its  Common  Stock to  permit  exercise  of all
outstanding  Rights in accordance  with this Section  13(a)) in connection  with
such consummation 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.


     (b) "Principal Party" shall mean:


          (i) in the case of any  transaction  described in clause (x) or (y) of
     the first  sentence of Section 13(a) hereof,  the Person that is the issuer
     of any  securities  into which  shares of Common  Stock of the  Company are
     converted  in such merger or  consolidation,  and if no  securities  are so
     issued, the Person,  including the Company,  that is the other party to the
     merger or consolidation; and


          (ii) in the case of any  transaction  described  in clause  (z) of the
     first  sentence  of 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;  provided,  however,  that in
     any case described in clause (i) or (ii) in this Section 13(b),  (x) if the
     Common  Stock  of  such  Person  is not at  such  time  and  has  not  been
     continuously over the preceding 12-month period registered under Section 12
     of the Exchange Act, and such Person is a direct or indirect  Subsidiary or
     Affiliate of another  Person,  "Principal  Party" shall refer to such other
     Person; (y) in case such Person is a Subsidiary, directly or indirectly, or
     Affiliate  of more than one Person,  the Common  Stocks of all of which are
     and have been so registered,  "Principal Party" shall refer to whichever of
     such  Persons  is the  issuer  of the  Common  Stock  having  the  greatest
     aggregate  market  value,  and (z) in case  such  Person  is,  or is  owned
     directly or indirectly  by, a partnership or joint venture formed by two or
     more  Persons  that are not  owned,  directly  or  indirectly,  by the same
     Person, the rules set forth in (x) and (y) above shall apply to each of the
     chains of  ownership  having an interest  in such joint  venture as if such
     party were a  "Subsidiary"  of both or all of such joint  venturers and the
     Principal  Parties in each such chain shall bear the  obligations set forth
     in this Section 13 in the same ratio as their direct or indirect  interests
     in such Person bear to the total of such interests.


     (c) The Company shall not consummate any such  consolidation,  merger, sale
or transfer unless the Principal Party shall have a sufficient  number of shares
of its  authorized  Common  Stock  which have not been  issued or  reserved  for
issuance to permit the  exercise in full of the Rights in  accordance  with this
Section 13 and unless  prior  thereto the Company and each  Principal  Party and
each other Person who may become a Principal Party as a result of such


                                       17
<PAGE>

consolidation, merger, sale or transfer shall have executed and delivered to the
Rights  Agent a  supplemental  agreement  providing  for the  terms set forth in
paragraphs (a) and (b) of this Section 13 and further providing that, as soon as
practicable  after the date of any  consolidation,  merger,  sale or transfer of
assets mentioned in paragraph (a) of this Section 13, the Principal Party will:


          (i) prepare and file a registration statement under the Securities Act
     with respect to the Rights and the securities  purchasable upon exercise of
     the Rights on an appropriate  form, will use its best efforts to cause such
     registration  statement to become  effective as soon as  practicable  after
     such  filing  and will  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 Expiration Date;


          (ii) use its best  efforts to qualify or  register  the Rights and the
     securities  purchasable  upon  exercise  of the Rights  under the "blue sky
     laws" of such jurisdictions as may be necessary or appropriate; and


          (iii) will  deliver to  holders  of the  Rights  historical  financial
     statements for the Principal Party and each of its Affiliates  which comply
     in all respects with the requirements for registration on Form 10 under the
     Exchange Act.


     The  provisions  of this  Section 13 shall  similarly  apply to  successive
mergers  or  consolidations  or sales or other  transfers.  In the event  that a
Section 13 Event shall occur at any time after the occurrence of a Section 11(b)
Event,  the Rights which have not theretofore  been exercised  shall  thereafter
also become exercisable in the manner described in Section 13(a) hereof.


     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 New York Stock  Exchange or,
if the  Rights  are not  listed or  admitted  to  trading  on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with  respect to  securities  listed or  admitted  to  trading on the  principal
national  securities  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, as reported by the Nasdaq National Market System or, if the
Rights are not listed or admitted to trading on any national securities exchange
or included in the Nasdaq National Market System,  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 Nasdaq or such other system then in use
or, if on any such date the Rights are not quoted by any such organization,  the
average of the  closing  bid and asked  prices as  furnished  by a  professional
market maker  making a market in the Rights  selected by a majority of the Board
of Directors. 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
a majority of the Board of Directors shall be used.


                                       18
<PAGE>

     (b) The  Company  shall not be  required  to issue  fractions  of shares of
Preferred  Stock (other than fractions  which are integral  multiples of one-two
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-two  hundredth of a
share of Preferred  Stock).  Fractions of shares of Preferred  Stock in integral
multiples  of  one-two  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 shares of Preferred  Stock  represented by
such depositary  receipts.  In lieu of fractional shares of Preferred Stock that
are not integral  multiples of one-two  hundredth of a share of Preferred Stock,
the Company may pay to the registered  holders of Right Certificates at the time
such Right Certificates are exercised as herein provided an amount in cash equal
to the same  fraction of the current  market  value of one-two  hundredths  of a
share of Preferred Stock. For purposes of this Section 14(b), the current market
value of  one-two  hundredth  of a share of  Preferred  Stock  shall be  one-two
hundredth  of the closing  price of a share of  Preferred  Stock (as  determined
pursuant to Section  11(f)(ii)  hereof) for the Trading Day immediately prior to
the date of such exercise.


     (c) Following the occurrence of one of the transactions or events specified
in  Section  11  hereof  giving  rise  to the  right  to  receive  common  stock
equivalents  (other than Preferred  Stock) or other securities upon the exercise
of a Right,  the Company  shall not be required to issue  fractions of shares or
units of such common stock  equivalents or other securities upon exercise of the
Rights or to distribute  certificates  which evidence  fractional shares of such
common stock  equivalents or other  securities.  In lieu of fractional shares or
units of such common stock equivalents or other securities,  the Company may 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 a share or unit of such common stock equivalent or other
securities.  For purposes of this Section 14(c),  the current market value shall
be  determined  in the manner set forth in Section  11(f) hereof for the Trading
Day  immediately  prior to the date of such  exercise  and, if such common stock
equivalent is not traded, each such common stock equivalent shall have the value
of one-two hundredth of a share of Preferred Stock.


     (d) Except as otherwise  expressly  provided in this Section 14, the holder
of a Right by the acceptance of the Right  expressly  waives such holder's right
to receive  any  fractional  Rights or any  fractional  share upon  exercise  of
Rights.


     Section  15.  Rights of  Action.  All  rights of action in  respect of this
Rights  Agreement,  except for rights of action  given to the Rights Agent under
Section 18 or Section 20 hereof, are vested in the respective registered holders
of the Right  Certificates  (and, prior to the Distribution Date, the registered
holders of Common  Stock);  and any registered  holder of any Right  Certificate
(or, prior to the Distribution  Date, of the Common Stock),  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 Stock), may, in such holder's own behalf
and for such holder's own benefit,  enforce,  and may institute and maintain any
suit, action or proceeding  against the Company to enforce,  or otherwise act in
respect of, such holder's  right to exercise the Rights  evidenced by such Right
Certificate in the manner provided in such Right  Certificate and in this Rights
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 Rights 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 Rights Agreement. Holders of Rights shall be entitled


                                       19
<PAGE>

to  recover  the  reasonable  costs and  expenses,  including  attorneys'  fees,
incurred  by them  in any  action  to  enforce  the  provisions  of this  Rights
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 Common Stock;


     (b) after the  Distribution  Date, the Right  Certificates are transferable
only on the registry books of the Rights Agent if surrendered at the stockholder
services office of the Rights Agent or such office  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 associated
Common Stock Certificate) is registered as the absolute owner thereof and of the
Rights evidenced thereby  (notwithstanding any notations of ownership or writing
on the Right  Certificate or the  associated  Common Stock  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.


     (d)  notwithstanding  anything in this Rights  Agreement  to the  contrary,
neither the Company nor the Rights Agent shall have any  liability to any holder
of a Right or other  Person as a result of its  inability  to perform any of its
obligations  under  this  Rights  Agreement  by  reason  of any  preliminary  or
permanent  injunction  or other  order,  decree or  ruling  issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency
or commission,  or any statute,  rule, regulation or executive order promulgated
or enacted by any governmental  authority  prohibiting or otherwise  restraining
performance of such obligation;  provided, however, the Company must, subject to
the good faith determination of its Board of Directors,  use its best efforts to
have any such order, decree or ruling lifted or otherwise  overturned as soon as
possible.


     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 Preferred Stock,  Common 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  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 Section 25 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or 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  Rights
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,


                                       20
<PAGE>

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
Rights  Agreement,  including  the costs and expenses of  defending  against any
claim of liability.


     (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 Rights Agreement in reliance upon any Right  Certificate
or certificate for Preferred Stock,  Common Stock 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.


     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
corporate trust powers or business or the stock transfer  business of the Rights
Agent or any successor Rights Agent,  shall be the successor to the Rights Agent
under this Rights 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 Rights  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 Rights 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 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 Rights Agreement.


     Section 20. Duties of Rights Agent.  The Rights Agent undertakes the duties
and  obligations  imposed by this Rights  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 Rights  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


                                       21
<PAGE>

herein  specifically  prescribed)  may be deemed to be  conclusively  proved and
established  by a  certificate  signed by the  Chairman of the Board,  the Chief
Executive  Officer,  President,  Chief  Financial  Officer or any Executive Vice
President and by the  Treasurer or any  Assistant  Treasurer or the Secretary or
any Assistant  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  Rights
Agreement in reliance upon such certificate.


     (c) The Rights Agent shall be liable hereunder only for its own negligence,
bad faith or willful 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 Rights  Agreement  or in the
Right  Certificates  (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 Rights  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  Rights  Agreement  or in any  Right
Certificate;  nor shall it be responsible for any adjustment  required under the
provisions of Sections 11 or 13 hereof or responsible for the manner,  method or
amount of any such adjustment or the ascertaining of the existence of facts that
would require any such adjustment (except with respect to the exercise of Rights
evidenced by Right  Certificates  after actual notice to the Rights Agent of any
such  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 Rights
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 the Rights Agent for the carrying  out or  performing  by the Rights Agent of
the provisions of this Rights Agreement.


     (g)  The  Rights  Agent  is  hereby   authorized  and  directed  to  accept
instructions  with respect to the  performance of its duties  hereunder from the
Chairman of the Board, the Chief Executive Officer,  President,  Chief Financial
Officer, any Executive Vice President,  the Secretary,  any Assistant Secretary,
the  Treasurer or any Assistant  Treasurer 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 to be taken by it in good faith
in accordance  with  instructions of any such officer or for any delay in acting
while waiting for those instructions.


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


                                       22
<PAGE>

     (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  that  reasonable  care was  exercised  in the
selection and continued employment thereof.


     (j) No provision of this Rights Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise  incur any financial  liability in the
performance  of any of its duties  hereunder or in the exercise of its rights if
there shall be reasonable  grounds for believing that repayment of such funds or
adequate  indemnification  against  such  risk or  liability  is not  reasonably
assured to it.


     (k) If, with respect to any Rights  Certificate  surrendered  to the Rights
Agent  for  exercise  or  transfer,  the  certificate  attached  to the  form of
assignment  or form of election to purchase,  as the case may be, has either not
been  completed  or  indicates  an  affirmative  response  to clause 1, clause 2
and/or,  in the case of the  certificate  attached  to the form of  election  to
purchase,  clause 3 thereof,  the Rights Agent shall not take any further action
with respect to such  requested  exercise of transfer  without first  consulting
with the Company.


     (l) No provision of this Rights Agreement shall require the Rights Agent to
independently  determine whether any Right  Certificate  issued pursuant to this
Rights  Agreement  is required  pursuant  to Section  3(c) to contain the legend
specified  in Section  3(c) and the Rights  Agent shall have no liability to any
holder of Rights  Certificates or other Person as a result of the failure of any
Right Certificate to contain such legend other than a Right  Certificate  issued
to a Person identified in a written certificate from the Company as an Acquiring
Person or an Affiliate or Associate of an Acquiring Person.


     Section  21.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights  Agent may resign and be  discharged  from its duties  under this  Rights
Agreement  upon 30 days'  notice in writing  mailed to the  Company  and to each
transfer  agent  of the  Common  Stock  and  Preferred  Stock by  registered  or
certified  mail,  and 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 Rights  Agent or  successor  Rights
Agent,  as the case may be, and to each  transfer  agent of the Common Stock and
Preferred Stock by registered or certified mail, and to the holders of the Right
Certificates by first-class mail or, prior to the Distribution Date, through any
filing made by the Company  pursuant to the  Exchange  Act. 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 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
(which holder shall,  with such notice,  submit such holder's 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) a corporation or other entity organized
and doing business under the laws of the United States or of any state,  in good
standing,  having  an  office  in the  States  of New York or  Kansas,  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 or
(b) an affiliate  of a  corporation  or other entity  described in clause (a) of
this sentence.  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


                                       23
<PAGE>

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 Stock and Preferred  Stock,  and mail a notice  thereof in writing to
the registered  holders of the Right  Certificates or, prior to the Distribution
Date, through any filing made by the Company pursuant to the Securities Exchange
Act of 1934,  as amended.  Failure to give any notice  provided for 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.


     (a)  Notwithstanding  any of the provisions of this Rights  Agreement or of
the Rights to the  contrary,  the Company  may,  at its option,  issue new Right
Certificates  evidencing Rights in such form as may be approved by a majority of
the Board of Directors then in office to reflect any adjustment or change in the
Purchase  Price  and the  number  or kind or class of  shares  of stock or other
securities  or  property  purchasable  under  the  Right  Certificates  made  in
accordance with the provisions of this Rights Agreement.


     (b) In addition,  in  connection  with the issuance or sale of Common Stock
following  the  Distribution  Date and  prior  to the  redemption,  exchange  or
expiration of the Rights, the Company (a) shall with respect to shares of Common
Stock so issued or sold  pursuant to the exercise of stock  options or under any
employee  benefit  plan or  arrangement,  or upon the  exercise,  conversion  or
exchange of securities  hereinafter  issued by the Company,  and (b) may, in any
other case, if deemed necessary or appropriate by the Board of Directors,  issue
Right  Certificates  representing the appropriate number of Rights in connection
with  such  issuance  or  sale;  provided,  however,  that  (i)  no  such  Right
Certificates  shall be issued if, and to the extent that,  the Company  shall be
advised  by  counsel  that such  issuance  would  create a  significant  risk of
material  adverse  tax  consequences  to the  Company or the Person to whom such
Right  Certificates  would be  issued,  and (ii) no Right  Certificate  shall be
issued if, and to the extent that,  appropriate  adjustment shall otherwise have
been made in lieu of the issuance thereof.


     Section 23. Redemption and Termination.


     (a) A majority of the Board of Directors then in office may, at its option,
at any time  prior to the  earlier  of (i) the  close of  business  on the tenth
Business Day following the Stock  Acquisition Date or (ii) the close of business
on the Final  Expiration  Date, elect to redeem all but not less than all of the
then  outstanding  Rights  at a  redemption  price  of  $0.0025  per  Right,  as
appropriately  adjusted to reflect any stock  split,  stock  dividend or similar
transaction  occurring  after  the date  hereof  (such  redemption  price  being
hereinafter  referred to as the "Redemption  Price").  Notwithstanding  anything
contained in this Agreement to the contrary, the Rights shall not be exercisable
after the first  occurrence  of a Section  11(b)  Event  until  such time as the
Company's  right of  redemption  hereunder  has expired.  The  redemption of the
Rights by the Board of Directors  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.


     (b)  Immediately  upon the action of a majority  of the Board of  Directors
then in office  electing  to  redeem  the  Rights,  evidence  of which  shall be
promptly filed with the Rights Agent, or, when appropriate, immediately upon the
time or  satisfaction  of such  conditions  as the Board of  Directors  may have
established, 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


                                       24
<PAGE>

give public  disclosure  of any such  redemption;  provided,  however,  that the
failure to give,  or any defect  in,  any such  disclosure  shall not affect the
validity  of such  redemption.  Within 10 days  after the action of the Board of
Directors  ordering the redemption of the Rights,  the Company shall give notice
of such redemption to the holders of the then outstanding Rights by mailing such
notice to all such  holders  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 Stock.  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 will state the method
by which the payment of the Redemption Price will be made.


     (c) Neither the Company nor any of its Affiliates or Associates may redeem,
acquire or  purchase  for value any Rights at any time in any manner  other than
that specifically set forth in this Section 23, Section 24 hereof and other than
in connection with the purchase of Common Stock prior to the Distribution Date.


     Section 24. Exchange.


     (a) The Board of Directors may, at its option, at any time after any Person
becomes an Acquiring  Person,  exchange all or part of the then  outstanding and
exercisable  Rights  (which  shall not  include  Rights  that have  become  void
pursuant  to the  provisions  of Section  7(e)  hereof)  for Common  Stock at an
exchange ratio of one share of Common Stock per Right, appropriately adjusted to
reflect  adjustments  in the  number of Rights  pursuant  to  Section 11 of this
Rights  Agreement  (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 after any Person  (other
than the Company,  any Subsidiary of the Company,  any employee  benefit plan or
compensation  arrangement of the Company or any such  Subsidiary,  or any entity
holding  securities  of  the  Company  to the  extent  organized,  appointed  or
established  by the Company or any such  Subsidiary for or pursuant to the terms
of any such employee  benefit plan or compensation  arrangement),  together with
all Affiliates and  Associates of such Person,  becomes the Beneficial  Owner of
50% or more of the Voting Power of the Company.


     (b)  Immediately  upon the action of the Board of  Directors  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 shares of Common Stock equal to the number of such
Rights  held by such  holder  multiplied  by the  Exchange  Ratio.  The  Company
promptly shall 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 promptly shall mail a notice of any such exchange
to all of the holders of such Rights 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 Common  Stock for Rights  will be  effected  and, in the event of any partial
exchange,  the number of Rights which 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 7(e) hereof) held
by each holder of Rights.


     (c) In any  exchange  pursuant  to this  Section  24, the  Company,  at its
option, may substitute  Preferred Stock (or equivalent  preferred stock, as such
term is defined in Section  11(d)  hereof)  for Common  Stock  exchangeable  for
Rights,  at the initial rate of one-two  hundredth of a share of Preferred Stock
(or equivalent preferred stock) for each share of Common Stock, as appropriately


                                       25
<PAGE>

adjusted to reflect  adjustments  in the voting  rights of the  Preferred  Stock
pursuant to the terms  thereof,  so that the  fraction  of a share of  Preferred
Stock delivered in lieu of each share of Common Stock shall have the same voting
rights as one share of Common Stock.


     (d) In the event that there shall not be sufficient  shares of Common Stock
or Preferred Stock (or equivalent preferred stock) issued but not outstanding or
authorized  but  unissued to permit any  exchange of Rights as  contemplated  in
accordance  with this Section 24, the Company  shall take all such action as may
be necessary to authorize  additional  shares of Common Stock or Preferred Stock
(or equivalent preferred stock) for issuance upon exchange of the Rights.


     (e) The Company shall not be required to issue fractions of Common Stock or
to distribute  certificates which evidence fractional shares of Common Stock. In
lieu of such  fractional  shares of Common  Stock,  the Company shall pay to the
registered  holders  of  the  Right  Certificates  with  regard  to  which  such
fractional  shares of Common Stock would otherwise be issuable an amount in cash
equal to the same  fraction  of the  current  market  value of a whole  share of
Common Stock.  For the purposes of this  paragraph (e), the current market value
of a whole share of Common Stock shall be the closing price of a share of Common
Stock (as determined pursuant to the second sentence of Section 11(f)(i) hereof)
for the Trading Day immediately  prior to the date of exchange  pursuant to this
Section 24.


     Section 25. Notice of Proposed Actions.


     (a) In case the Company  shall  propose at any time after the  Distribution
Date (a) to pay any dividend payable in stock of any class to the holders of the
Preferred  Stock  or to  make  any  other  distribution  to the  holders  of the
Preferred Stock (other than a regular  periodic cash dividend out of earnings or
retained earnings of the Company),  (b) to offer to the holders of the Preferred
Stock rights or warrants to subscribe for or to purchase any  additional  shares
of  Preferred  Stock  or  shares  of  stock  of any  other  class  or any  other
securities,  rights  or  options,  (c) to  effect  any  reclassification  of the
Preferred Stock (other than a reclassification involving only the subdivision of
outstanding  shares of  Preferred  Stock),  (d) to effect any  consolidation  or
merger into or with,  or to effect any sale or other  transfer (or to permit one
or more of its  Subsidiaries to effect any sales or other  transfer),  in one or
more transactions,  of 50% or more of the assets or earning power of the Company
and its Subsidiaries  (taken as a whole) to, any other Person, (e) to effect the
liquidation,  dissolution or winding up of the Company, or (f) to declare or pay
any  dividend  on the  Common  Stock  payable  in  Common  Stock or to  effect a
subdivision,   combination   or   consolidation   of  the   Common   Stock   (by
reclassification  or otherwise  than by payment of  dividends in Common  Stock),
then, in each such case,  the Company  shall give to each holder of a Right,  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, distribution of
rights or warrants, or the date on which such  reclassification,  consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to take place
and the date of participation  therein by the holders of the Common Stock and/or
Preferred Stock, if any such date is to be fixed.  Such notice shall be so given
in the case of any action  covered by clauses (a) or (b) above at least ten 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 ten
days  prior to the date of the  taking  of such  proposed  action or the date of
participation therein by the holders of Preferred Stock,  whichever shall be the
earlier.  The failure to give notice  required by this  Section 25 or any defect
therein  shall not affect the  legality or  validity of the action  taken by the
Company or the vote upon any such action.


     (b) In case a Section  11(b) Event shall occur,  then the Company  shall as
soon as practicable thereafter give to each holder of a Right Certificate, in


                                       26
<PAGE>

accordance  with Section 26 hereof,  a notice of the  occurrence  of such event,
which shall  specify the event and the  consequences  of the event to holders of
Rights under Section 11(b) hereof.


     Section 26. Notices. Notices or demands authorized by this Rights 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

     Section 27.  Supplements and Amendments.  The Company may from time to time
supplement or amend this Rights Agreement without the approval of any holders of
Right  Certificates  in  order  (a) to cure any  ambiguity,  (b) to  correct  or
supplement any provision contained herein which may be defective or inconsistent
with any other  provisions  herein,  (c) to shorten or lengthen  any time period
hereunder  (including  without  limitation to extend the Final Expiration Date),

manner  which would  adversely  affect the  interests  of the holders of Rights;
provided  further that this Rights  Agreement may not be supplemented or amended
to  lengthen  pursuant  to  clause  (c) of this  sentence,  (A) the time  period
relating  to the when the Rights may be  redeemed at such time as the Rights are
not then redeemable, or (B) any other time period unless such lengthening is for
the purpose of  protecting,  enhancing or  clarifying  the rights of, and/or the
benefits to, the holders of the Rights;  provided further that the Company shall
have the right to make  unilaterally  any changes  necessary to  facilitate  the
appointment of a successor  Rights Agent,  which such changes shall be set forth
in a writing by the Company or by the Company and such  successor  Rights Agent.
Without  limiting the foregoing,  the Company may at any time prior to such time
as any Person becomes an Acquiring  Person amend this Rights  Agreement to lower

the Voting  Power of the Company  then known by the  Company to be  beneficially
owned by any Person (other than the Company,  any Subsidiary of the Company,  or
any employee benefit plan or compensation arrangement of the Company or any


                                       27

Subsidiary of the Company,  and any entity holding  securities of the Company to

compensation  arrangement)  together with all  Affiliates and Associates of such
Person and (ii) 10%.  Upon the  delivery of a  certificate  from an  appropriate

Agreement  by or for the benefit of the  Company or the Rights  Agent shall bind

shall be  construed  to give to any Person  other than the  Company,  the Rights
Agent and the registered  holders of the Right  Certificates  (and, prior to the
Distribution  Date,  the Common Stock) any legal or equitable  right,  remedy or
claim under this Rights  Agreement;  but this Rights  Agreement shall be for the
sole and exclusive  benefit of the Company,  the Rights Agent and the registered
holders of the Right  Certificates  (and,  prior to the  Distribution  Date, the
Common Stock).


     Section 30. Severability.  If any term, provision,  covenant or restriction
of this Rights  Agreement is held by a court of competent  jurisdiction or other

                           BUTLER NATIONAL CORPORATION



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




     I,  Clark  D.  Stewart,   President  of  Butler  National  Corporation,   a
corporation  organized  and existing  under the General  Corporation  Law of the
State of Delaware,  in accordance with the provisions of Section 151 thereof, DO
HEREBY CERTIFY:


     That pursuant to the authority conferred upon the Board of Directors by the
Certificate  of  Incorporation,  as amended,  of the Company,  the said Board of
Directors adopted the following resolution:


          RESOLVED,  that  pursuant  to the  authority  vested  in the  Board of
     Directors  of  the  Company  in  accordance  with  the  provisions  of  its
     Certificate of  Incorporation,  as amended,  a series of Preferred Stock of
     the  Company  be and it hereby is  created,  and that the  designation  and
     amount  thereof and the powers,  preferences  and relative,  participating,
     optional and other  special  rights of the shares of such  series,  and the
     qualifications, limitations or restrictions thereof are as follows:


     Section 1. Designation and Amount.


     There shall be a series of the Preferred Stock which shall be designated as
the "Series C Participating Preferred Stock," par value $5.00 per share, and the
number of shares  constituting  such  series  shall be  100,000.  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 C
Participating  Preferred  Stock to a number  less than that of the  shares  then
outstanding  plus the number of shares  issuable  upon  exercise of  outstanding
rights,  options or warrants or upon conversion of outstanding securities issued
by the Company.


     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  ranking  prior and  superior  to the  Series C
Participating  Preferred Stock with respect to dividends,  the holders of shares
of Series C  Participating  Preferred  Stock,  in  preference  to the holders of
shares of Common  Stock,  par value $.01 per share of the Company  (the  "Common
Stock"),  and of any other junior 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 any regular quarterly dividend
payment date as shall be established  by the Board of Directors  (each such date
being referred to herein as a "Quarterly Dividend Payment Date"),  commencing on
the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series C Participating  Preferred Stock, in an amount per
share  (rounded  to the  nearest  cent) equal to the greater of (a) $1.00 or (b)
subject to the provision for  adjustment  hereinafter  set forth,  200 times the
aggregate per share amount of all cash dividends, and 200 times the aggregate



<PAGE>

per  share  amount  (payable  in  kind)  of  all  non-cash  dividends  or  other
distributions,  other  than a dividend  payable  in shares of Common  Stock or a
subdivision of the outstanding  shares of Common Stock (by  reclassification  or
otherwise),  declared  on the  Common  Stock  since  the  immediately  preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment  Date,  since the first  issuance of any share or fraction of a share of
Series C  Participating  Preferred  Stock. In the event the Company shall at any
time after October 26, 1998 (the "Rights  Declaration  Date") declare or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in  each  such  case  the  amount  to  which  holders  of  shares  of  Series  C
Participating  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 shares of Common
Stock  outstanding  immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding  immediately prior to
such event.


     (B) The Company  shall declare a dividend or  distribution  on the Series C
Participating  Preferred  Stock as provided  in  paragraph  (A) of this  Section
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or  distribution  shall have been declared on the Common Stock
during the period  between  any  Quarterly  Dividend  Payment  Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series C  Participating  Preferred  Stock shall  nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.


     (C) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series C Participating  Preferred Stock from the Quarterly  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  Quarterly  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  Quarterly
Dividend  Payment Date or is a date after the record date for the  determination
of holders  of shares of Series C  Participating  Preferred  Stock  entitled  to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such  dividends  shall begin to accrue and be  cumulative
from such Quarterly  Dividend  Payment Date.  Accrued but unpaid dividends shall
not bear  interest.  Dividends  paid on the  shares  of  Series C  Participating
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, in  accordance  with  applicable  law, fix a record date for the
determination  of holders of shares of Series C  Participating  Preferred  Stock
entitled to receive  payment of a dividend  or  distribution  declared  thereon,
which  record  date shall be not more than such number of days prior to the date
fixed for the payment thereof as may be allowed by applicable law.


     Section 3. Voting Rights.


     The holders of shares of Series C Participating  Preferred Stock shall have
the following voting rights:


     (A) Each share of Series C Participating  Preferred Stock shall entitle the
holder  thereof  to  200  votes  on  all  matters  submitted  to a  vote  of the
stockholders  of the Company.  In the event the Company  shall at any time after
the Rights Declaration Date declare or pay any dividend on the Common Stock


                                       2
<PAGE>

payable in shares of Common Stock,  or effect a subdivision  or  combination  or
consolidation of the outstanding shares of Common Stock (by  reclassification or
otherwise  than by  payment  of a  dividend  in shares of Common  Stock)  into a
greater or lesser number of shares of Common  Stock,  then in each such case the
number of votes to which holders of shares of Series C  Participating  Preferred
Stock were entitled immediately prior to such event under the preceding sentence
shall be adjusted by  multiplying  such amount by a fraction,  the  numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.


     (B) Except as otherwise  provided herein,  in the Company's  Certificate of
Incorporation  or by law,  the  holders  of  shares  of  Series C  Participating
Preferred  Stock,  the  holders of shares of Common  Stock,  and the  holders of
shares of 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 otherwise set forth herein or in the Company's Certificate of
Incorporation,  and except as  otherwise  provided  by law,  holders of Series C
Participating  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  Stock as set forth  herein)  for  taking any  corporate
action.


     Section 4. Certain Restrictions.


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


          (i) declare or pay dividends on, make any other  distributions  on, or
     redeem or purchase or  otherwise  acquire for  consideration  any shares of
     stock  ranking  junior  (either  as  to  dividends  or  upon   liquidation,
     dissolution or winding up) to the Series C Participating Preferred Stock;


          (ii) declare or pay  dividends on or make any other  distributions  on
     any shares of stock  ranking on a parity  (either as to  dividends  or upon
     liquidation,  dissolution  or winding  up) with the Series C  Participating
     Preferred   Stock,   except   dividends   paid  ratably  on  the  Series  C
     Participating  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)  except  as  permitted  in  Section  4(A)(iv)  below,  redeem or
     purchase or otherwise acquire for consideration shares of any stock ranking
     on a parity  (either as to dividends or upon  liquidation,  dissolution  or
     winding up) with the Series C Participating  Preferred Stock, provided that
     the Company may at any time redeem, purchase or otherwise acquire shares of
     any such parity  stock in  exchange  for shares of any stock of the Company
     ranking junior (either as to dividends or upon dissolution,  liquidation or
     winding up) to the Series C Participating Preferred Stock; and


          (iv)  purchase or otherwise  acquire for  consideration  any shares of
     Series C Participating Preferred Stock, or any shares of stock ranking on a
     parity  with  the  Series  C  Participating   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


                                       3
<PAGE>

     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 C Participating Preferred Stock purchased or otherwise
acquired by the Company in any manner  whatsoever  shall be retired and canceled
promptly after the acquisition  thereof. The Company shall cause all such shares
upon their  cancellation to be authorized but unissued shares of Preferred Stock
which may be reissued as part of a new series of Preferred Stock, subject to the
conditions and restrictions on issuance set forth herein.


     Section 6. Liquidation, Dissolution or Winding Up.


     (A)  Subject  to the  rights of the  holders of any shares of any series of
Preferred  Stock of the  Company  ranking  prior and  superior  to the  Series C
Participating Preferred Stock with respect to liquidation,  upon any liquidation
(voluntary  or  otherwise),  dissolution  or  winding  up  of  the  Company,  no
distribution  shall be made to the  holders  of shares of stock  ranking  junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series C  Participating  Preferred Stock unless,  prior thereto,  the holders of
shares of Series C Participating Preferred Stock shall have received $200.00 per
share,  plus an amount equal to accrued and unpaid  dividends and  distributions
thereon,  whether or not  declared,  to the date of such  payment (the "Series C
Liquidation Preference"). Following the payment of the full amount of the Series
C  Liquidation  Preference,  no  additional  distributions  shall be made to the
holders  of shares of Series C  Participating  Preferred  Stock,  unless,  prior
thereto, the holders of shares of Common Stock shall have received an amount per
share (the "Common  Adjustment")  equal to the quotient obtained by dividing (i)
the Series C Liquidation  Preference by (ii) 200 (as  appropriately  adjusted as
set forth in subparagraph C below to reflect such events as stock dividends, and
subdivisions,  combinations and consolidations with respect to the Common Stock)
(such  number in clause  (ii) being  referred  to as the  "Adjustment  Number").
Following the payment of the full amount of the Series C Liquidation  Preference
and the  Common  Adjustment  in respect  of all  outstanding  shares of Series C
Participating Preferred Stock and Common Stock, respectively,  holders of Series
C  Participating  Preferred  Stock and  holders of shares of Common  Stock shall
receive their  ratable and  proportionate  share of the  remaining  assets to be
distributed  in the ratio of the  Adjustment  Number to 1 with  respect  to such
Series C  Participating  Preferred Stock and Common Stock, on a per share basis,
respectively.


     (B) In the  event  there  are not  sufficient  assets  available  to permit
payment  in full of the  Series C  Liquidation  Preference  and the  liquidation
preferences  of all other series of  preferred  stock,  if any,  which rank on a
parity with the Series C  Participating  Preferred  Stock,  then such  remaining
assets  shall be  distributed  ratably to the holders of such  parity  shares in
proportion to their respective liquidation  preferences.  In the event there are
not  sufficient  assets  available  to  permit  payment  in full  of the  Common
Adjustment,  then such  remaining  assets  shall be  distributed  ratably to the
holders of Common Stock.


     (C) In the event the Company shall at any time after the Rights Declaration
Date  declare or pay any  dividend on Common  Stock  payable in shares of Common
Stock,  or  effect  a  subdivision  or  combination  or   consolidation  of  the
outstanding shares of Common Stock (by reclassification or otherwise than by


                                       4
<PAGE>

payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares  of Common  Stock,  then in each  such case the  Adjustment  Number in
effect  immediately  prior to such event shall be adjusted by  multiplying  such
Adjustment  Number by a fraction the  numerator of which is the number of shares
of Common Stock outstanding  immediately after such event and the denominator of
which is the number of shares of Common Stock 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 shares of Common Stock are  exchanged for or
changed into other stock or securities,  cash and/or any other property, then in
any such case the shares of Series C Participating  Preferred Stock shall at the
same time be similarly  exchanged or changed in an amount per share  (subject to
the  provision  for  adjustment  hereinafter  set forth)  equal to 200 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 share of Common Stock
is changed or  exchanged.  In the event the Company  shall at any time after the
Rights  Declaration  Date declare or pay any dividend on Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or  consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by  payment of a dividend  in shares of Common  Stock)  into a greater or lesser
number of shares of Common Stock, then in each such case the amount set forth in
the  preceding  sentence  with  respect to the  exchange  or change of shares of
Series C  Participating  Preferred  Stock shall be adjusted by multiplying  such
amount by a fraction  the  numerator  of which is the number of shares of Common
Stock  outstanding  immediately after such event and the denominator of which is
the number of shares of Common Stock that are outstanding  immediately  prior to
such event.


     Section 8. Redemption.


     The  shares  of  Series  C  Participating  Preferred  Stock  shall  not  be
redeemable.


     Section 9. Ranking.


     The Series C  Participating  Preferred Stock shall rank junior to all other
series of the Company's  Preferred  Stock as to the payment of dividends and the
distribution  of  assets,  unless  the terms of any such  series  shall  provide
otherwise.


     Section 10. Fractional Shares.


     Series C  Participating  Preferred  Stock may be issued in  fractions  of a
share which shall entitle the holder, in proportion to such holder's  fractional
shares,   to  exercise  voting  rights,   receive   dividends,   participate  in
distributions and to have the benefit of all other rights of holders of Series C
Participating Preferred Stock.

                           Butler National Corporation

                           Summary of Preferred Stock
                                 Purchase Rights


     On October 27, 1998, the Board of Directors of Butler National  Corporation
(the  "Company")  declared a dividend of one preferred  share  purchase right (a
"Right") for each outstanding  share of Common Stock, par value $0.01 per share,
of the Company (the "Common  Stock").  The dividend  distribution  is payable on
October 27, 1998 (the "Record Date") to the stockholders of record on that date.
Each Right entitles the registered  holder to purchase from the Company  one-two
hundredth of a share of Series C Participating  Preferred Stock, par value $5.00
per share  (the  "Preferred  Stock")  of the  Company  at a price of $10.00  per
one-two hundredth of a share of Preferred Stock (the "Purchase Price"),  subject
to adjustment. The description and terms of the Rights are set forth in a Rights
Agreement  dated as of October 26, 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) the  close of  business  on the  tenth
business day following the date of public  announcement or the date on which the
Company first has notice or  determines  that a person or group of affiliated or
associated persons (other than the Company, any subsidiary of the Company or any
employee benefit plan of the Company) (an "Acquiring  Person") has acquired,  or
obtained the right to acquire,  15% or more of the outstanding  shares of voting
stock of the Company  without the prior express  written  consent of the Company
executed  on behalf of the Company by a duly  authorized  officer of the Company
following  express  approval  by action of at least a majority of the members of
the Board of Directors then in office (the "Stock Acquisition Date") or (ii) the
close of  business  on the  tenth  business  day (or such  later  date as may be
determined  by  action of the Board of  Directors  but not later  than the Stock
Acquisition  Date)  following  the  commencement  of a tender  offer or exchange
offer, without the prior written consent of the Company, by a person (other than
the Company,  any  subsidiary of the Company or an employee  benefit plan of the
Company) which, upon  consummation,  would result in such party's control of 15%
or more of the Company's voting stock (the earlier of the dates in clause (i) or
(ii) above being called the "Distribution  Date"), the Rights will be evidenced,
with  respect  to any of the Common  Stock  certificates  outstanding  as of the
Record Date, by such Common Stock certificates.


     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 Company's Common Stock.  Until the  Distribution  Date (or earlier
redemption, exchange or expiration of the Rights), new Common Stock certificates
issued after the Record Date upon transfer or new issuances of Common Stock will
contain a notation  incorporating  the Rights Agreement by reference.  Until the
Distribution Date (or earlier redemption, exchange or expiration of the Rights),
the  surrender  for  transfer  of any  certificates  for shares of Common  Stock
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 Stock  represented by such  certificate.  As soon as practicable
following the Distribution  Date,  separate  certificates  evidencing the Rights
("Right  Certificates")  will be mailed to holders of record of the Common Stock
as of the  close  of  business  on  the  Distribution  Date  and  such  separate
certificates alone will then evidence the Rights.


     The Rights are not exercisable until the Distribution Date. The Rights will
expire,  if not  previously  exercised,  on the date  which is 10 years from the
Record Date (the "Final Expiration  Date"),  unless the Final Expiration Date is
extended or unless the Rights are earlier redeemed or exchanged by the Company.



<PAGE>

     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 and the number of one-two hundredths of a
share of Preferred  Stock  issuable upon exercise of each Right are also subject
to  adjustment  in the  event of a stock  split of the  Common  Stock or a stock
dividend on the Common Stock payable in shares of Common Stock or  subdivisions,
consolidations or combinations of the Common Stock occurring,  in any such case,
prior to the Distribution Date.


     Shares of Preferred Stock  purchasable upon exercise of the Rights will not
be redeemable or convertible to any other series of preferred  stock the Company
may issue (unless otherwise provided in the terms of such stock).  Each share of
Preferred  Stock will have a  preferential  dividend  in an amount  equal to 200
times any  dividend  declared  on each  share of Common  Stock.  In the event of
liquidation,  the  holders  of the  Preferred  Stock  will  receive a  preferred
liquidation  payment of equal to the  greater of $200 and 200 times the  payment
made per share of Common  Stock.  Each  share of  Preferred  Stock will have 200
votes,  voting  together  with the  Common  Stock.  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 200
times the amount and type of  consideration  received per share of Common Stock.
The rights of the Preferred Stock as to dividends,  liquidation and voting,  and
in  the  event  of  mergers  and  consolidations,  are  protected  by  customary
antidilution provisions.


     Because of the nature of the Preferred  Stock's  dividend,  liquidation and
voting  rights,  the  value  of the  one-two  hundredth  interest  in a share of
Preferred Stock  purchasable upon exercise of each Right should  approximate the
value of one share of Common Stock.


     If any person or group  (other  than the  Company,  any  subsidiary  of the
Company or any employee benefit plan of the Company) acquires 15% or more of the
Company's  outstanding  voting stock  without the prior  written  consent of the
Board of Directors, each Right, except those held by such persons, would entitle
each holder of a Right to acquire such number of shares of the Company's  Common
Stock as shall  equal  the  result  obtained  by  multiplying  the then  current
Purchase Price by the number of one-two hundredths of a share of Preferred Stock
for which a Right is then  exercisable  and dividing  that product by 50% of the
then current per-share market price of Company Common Stock.


     If any person or group  (other  than the  Company,  any  subsidiary  of the
Company or any employee benefit plan of the Company)  acquires more than 15% but
less than 50% of the  outstanding  Company  Common Stock  without  prior written
consent  of the  Board of  Directors,  each  Right,  except  those  held by such
persons,  may be exchanged  by the Board of  Directors  for one share of Company
Common Stock.


     If the  Company  were  acquired in a merger or other  business  combination
transaction where the Company is not the surviving  corporation or where Company
Common Stock is exchanged or changed or 50% or more of the  Company's  assets or
earnings power is sold in one or several  transactions without the prior written
consent of the Board of Directors,  each Right would entitle the holders thereof
(except  for the  Acquiring  Person)  to  receive  such  number of shares of the
acquiring company's common stock as shall be equal to the result obtained by


                                       2
<PAGE>

multiplying the then current Purchase Price by the number one-two  hundredths of
a share of Preferred  Stock for which a Right is then  exercisable  and dividing
that  product by 50% of the then  current  market  price per share of the common
stock of the  acquiring  company  on the date of such  merger or other  business
combination transaction.


     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-two  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 $.0025 per Right (the  "Redemption  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.
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.


     The terms of the Rights may be  amended  by the Board of  Directors  of the
Company  without the consent of the  holders of the Rights,  including,  but not
limited to, an amendment to lower certain thresholds described above to not less
than the greater of (i) any  percentage  greater than the largest  percentage of
the voting power of all  securities  of the Company then known to the Company to
be beneficially owned by any person or group of affiliated or associated persons
(other  than an excepted  person) and (ii) 10%,  except that from and after such
time as any  person or group of  affiliated  or  associated  persons  becomes an
Acquiring  Person no such  amendment may  adversely  affect the interests of the
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  has been filed  with the  Securities  and
Exchange Commission as an Exhibit to a Registration  Statement on Form 8-A dated
_________.  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.

                                                                      Exhibit 99


FOR IMMEDIATE RELEASE

          Butler  National   Corporation   DECLARES  DIVIDEND   DISTRIBUTION  OF
          PREFERRED STOCK PURCHASE RIGHTS

     [OLATHE,  KANSAS],  October 26, 1998 - On October  26,  1998,  the Board of
Directors of Butler National Corporation (Nasdaq: BUKS) approved the adoption of
a Shareholder Rights Plan designed to discourage  takeovers that involve abusive
tactics or do not provide fair value to  shareholders.  Similar  plans have been
adopted by many other publicly traded companies.

     Clark D. Stewart,  President of the Company stated, "The Board of Directors
determined  that  adopting  the  Shareholder  Rights  Plan is an  effective  and
reasonable  method  to  safeguard  the  interests  of our  shareholders.  We are
particularly  concerned  that  the  future  benefits  of  current  programs  and
initiatives  could be denied to  shareholders by an  opportunistic,  undervalued
acquisition of the Company. The plan is designed to assure that shareholders are
not  deprived  of their  rights to share in the full  measure  of the  Company's
long-term potential, while not preventing a fully valued bid for the Company."

     The  Shareholder  Rights Plan provides for a dividend  distribution  of one
Preferred  Stock Purchase Right for each  outstanding  share of Butler  National
Corporation common stock. The dividend distribution will be made to shareholders
of record on October 27, 1998. Each shareholder is automatically entitled to the
Rights and no physical  distribution  of new  certificates  will be made at this
time. The Rights distribution is not taxable to shareholders.

     The  Rights  will be  exercisable  only if a person  or group  (except  for
certain  exempted  persons or groups)  acquires  15% or more of Butler  National
Corporation's  common  stock or  announces a tender  offer which would result in
ownership of 15% or more of the common stock.  The Rights  entitle the holder to
purchase one two-hundredth of a share of Series C Participating  Preferred Stock
at an exercise price of $10.00 and will expire ten years from issuance.

     Following the acquisition of 15% or more of Butler  National  Corporation's
common  stock by a person or group,  the  holders of the Rights  (other than the
acquiring  person)  will be  entitled  to  purchase  shares of  common  stock at
one-half the then current market price, and, in the event of a subsequent merger
or other  acquisition  of the  Company,  to buy  shares of  common  stock of the
acquiring entity at one-half of the market price of those shares.

     Butler  National  Corporation  will be able to redeem the Rights at $0.0025
per  Right at any  time  until a person  or  group  acquires  15% or more of the
Company's shares.

     A letter outlining the Shareholder  Rights Plan in more detail will be sent
to the Company's shareholders following the record date.

         The common stock of Butler National Corporation is traded on the NASDAQ
under the symbol " BUKS."
