                                RIGHTS AGREEMENT

                  This  Rights  Agreement,  dated  as  of  July  18,  2000  (the
"Agreement"),  between Kirby Corporation,  a Nevada corporation (the "Company"),
and Fleet National Bank, a national banking association (the "Rights Agent"),

                              W I T N E S S E T H:
                              - - - - - - - - - -

                  WHEREAS,  on July 18, 2000 (the "Rights  Dividend  Declaration
Date"), the Board of Directors of the Company authorized and declared a dividend
of one Right for each share of common  stock,  par value $.10 per share,  of the
Company (the "Common Stock")  outstanding at the close of business on August 15,
2000 (the "Record Date"),  and has authorized the issuance of one Right (as such
number may  hereinafter be adjusted  pursuant to the provisions of Section 11(p)
hereof) for each share of Common Stock of the Company issued (whether originally
issued or delivered from the Company's treasury) between the Record Date and the
earlier of the  Distribution  Date (as  hereinafter  defined) and the Expiration
Date (as hereinafter  defined),  and, in certain  circumstances  provided for in
Section  22  hereof,   after  the   Distribution   Date,  each  Right  initially
representing the right to purchase one Fractional Share (as hereinafter defined)
of Series A Junior Participating  Preferred Stock of the Company, upon the terms
and subject to the conditions hereinafter set forth (the "Rights");

                  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
Agreement, the following terms shall have the meanings indicated:

                  "Acquiring  Person"  shall  mean  any  Person  who  or  which,
together  with  all  Affiliates  and  Associates  of such  Person,  shall be the
Beneficial Owner of 15% or more of the shares of Common Stock then  outstanding,
but shall not include any Exempt Person; provided,  however, that a Person shall
not be or  become  an  Acquiring  Person  if  such  Person,  together  with  its
Affiliates and Associates,  shall become the Beneficial  Owner of 15% or more of
the shares of Common Stock then outstanding solely as a result of a reduction in
the number of shares of Common Stock outstanding due to the repurchase of Common
Stock by the Company, unless and until such time as such Person or any Affiliate
or Associate of such Person shall  purchase or otherwise  become the  Beneficial
Owner of additional  shares of Common Stock  constituting 1% or more of the then
outstanding  shares of Common  Stock or any other Person (or Persons) who is (or
collectively are) the Beneficial Owner of shares of Common Stock constituting 1%
or more of the then outstanding shares of Common Stock shall become an Affiliate
or Associate of such Person, unless, in either such case, such Person,  together
with all Affiliates  and  Associates of such Person,  is not then the Beneficial
Owner  of 15% or more of the  shares  of  Common  Stock  then  outstanding;  and
provided,  further,  that if there is at least one  Continuing  Director then in
office and the Board of  Directors,  with the  concurrence  of a majority of the
Continuing Directors then in office, determines in good faith that a Person that
would  otherwise  be  an  "Acquiring   Person"  has  become  such  inadvertently
(including,  without  limitation,  because (i) such  Person was unaware  that it
beneficially  owned a percentage of Common Stock that would otherwise cause such
Person to be an "Acquiring Person" or (ii) such Person was aware of the


                                       -1-


<PAGE>



extent of its Beneficial  Ownership of Common Stock but had no actual  knowledge
of the  consequences  of such  Beneficial  Ownership  under this  Agreement) and
without any intention of changing or influencing control of the Company,  and if
such Person as promptly as practicable  divested or divests itself of Beneficial
Ownership of a  sufficient  number of shares of Common Stock so that such Person
would no longer be an  "Acquiring  Person," then such Person shall not be deemed
to be or to  have  become  an  "Acquiring  Person"  for  any  purposes  of  this
Agreement.

                  Notwithstanding  anything  in this  definition  of  "Acquiring
Person" to the contrary, so long as Charles Berdon Lawrence,  the Charles Berdon
Lawrence  GST Trust I, the  Charles  Berdon  Lawrence  GST Trust II, the Charles
Berdon  Lawrence  GST Trust III, the Charles  Berdon  Lawrence GST Trust IV, the
Berdon  Lawrence 1999 Retained  Annuity Trust and the trustees of such trusts in
their  capacities as such,  together with all  Affiliates and Associates of such
Persons, remain the Beneficial Owner of 15% or more of the outstanding shares of
Common Stock,  such Persons and any Affiliate or Associate  thereof shall not be
or become an  Acquiring  Person  unless  and until  such  Persons  become in the
aggregate the Beneficial Owner of 23% or more of the shares of Common Stock then
outstanding;  provided,  however,  that any such  Person  shall  not  become  an
Acquiring Person if such Person,  together with all Affiliates and Associates of
such Person,  shall become the Beneficial  Owner of 23% or more of the shares of
Common Stock then outstanding solely as a result of a reduction in the number of
shares of Common Stock  outstanding due to the repurchase of Common Stock by the
Company, unless and until such time as such Person or any Affiliate or Associate
thereof shall purchase or otherwise  become the  Beneficial  Owner of additional
shares of Common Stock constituting 1% or more of the then outstanding shares of
Common Stock or any other Person (or Persons) who is (or  collectively  are) the
Beneficial  Owner of shares of Common Stock  constituting 1% or more of the then
outstanding  shares of Common  Stock shall  become an  Affiliate or Associate of
such  Person  unless,  in either  such  case,  such  Person,  together  with all
Affiliates  and Associates of such Person,  is not then the Beneficial  Owner of
15% or more of the shares of Common Stock then outstanding.

                  "Adjustment  Shares"  shall  have  the  meaning  set  forth in
Section 11(a)(ii) hereof.

                  "Affiliate"  shall have the  meaning  ascribed to such term in
Rule 12b-2 of the General  Rules and  Regulations  under the Exchange Act, as in
effect on the date of this Agreement.

                  "Associate" shall mean, with reference to any Person,  (1) any
corporation,  firm,  partnership,  association,  unincorporated  organization or
other entity  (other than the Company or a  Subsidiary  of the Company) of which
such Person is an officer or general partner (or officer or general partner of a
general  partner) or is, directly or indirectly,  the Beneficial Owner of 10% or
more of any class of equity  securities,  (2) any trust or other estate in which
such  Person has a  substantial  beneficial  interest or as to which such Person
serves as trustee or in a similar  fiduciary  capacity  and (3) any  relative or
spouse of such Person, or any relative of such spouse,  who has the same home as
such Person.

                  A Person shall be deemed the "Beneficial  Owner" of, and shall
be deemed to "beneficially own," any securities:


                                       -2-

                  (i) that such  Person or any of such  Person's  Affiliates  or
         Associates,  directly or indirectly,  is the "beneficial  owner" of (as
         determined  pursuant to Rule 13d-3 of the General Rules and Regulations
         under the Exchange Act as in effect on the date of this  Agreement)  or
         otherwise  has the right to vote or dispose of,  including  pursuant to
         any  agreement,   arrangement  or  understanding  (whether  or  not  in

         "Beneficial  Owner" of, or to  "beneficially  own," any security  under
         this  subparagraph  (i) as a result  of an  agreement,  arrangement  or
         understanding  to vote such security if such agreement,  arrangement or
         understanding:  (A) arises  solely  from a  revocable  proxy or consent
         given in  response to a public  (i.e.,  not  including  a  solicitation

         consent  solicitation  made  pursuant to, and in accordance  with,  the
         applicable  provisions of the General Rules and  Regulations  under the
         Exchange Act and (B) is not then  reportable by such Person on Schedule
         13D under the Exchange Act (or any comparable or successor report);

                  (ii) that such Person or any of such  Person's  Affiliates  or
         Associates,  directly or  indirectly,  has the right or  obligation  to
         acquire  (whether such right or obligation is  exercisable or effective
         immediately  or only after the passage of time or the  occurrence of an
         event) pursuant to any agreement, arrangement or understanding (whether
         or not in writing) or upon the exercise of conversion rights,  exchange
         rights,  other rights,  warrants or options,  or  otherwise;  provided,
         however,  that a Person shall not be deemed the "Beneficial  Owner" of,

         or  exchange  offer  made  by  such  Person  or  any of  such  Person's
         Affiliates or Associates  until such tendered  securities  are accepted
         for purchase or exchange,  (B)  securities  issuable  upon  exercise of
         Rights at any time prior to the  occurrence of a Triggering  Event,  or

         "Original  Rights")  or  pursuant  to  Section  11(i) or (p)  hereof in
         connection with an adjustment made with respect to any Original Rights;

         (A) any other Person (or any Affiliate or Associate thereof) with which
         such Person or any of such Person's  Affiliates  or Associates  has any
         agreement, arrangement or understanding (whether or not in writing) for
         the  purpose  of  acquiring,  holding,  voting  (except  pursuant  to a
         revocable  proxy or consent as described in the proviso to subparagraph
         (i) of this  definition)  or disposing of any voting  securities of the
         Company or (B) any group (as that term is used in Rule  13d-5(b) of the
         General Rules and  Regulations  under the Exchange Act, as in effect on
         the date of this Agreement) of which such Person is a member;

provided,  however, that nothing in this definition shall cause a Person engaged

                  Section 2.  Appointment  of Rights Agent.  The Company  hereby

Section 3 hereof,  shall prior to the  Distribution  Date also be the holders of
the Common Stock)  (although it is expressly  agreed that the Rights Agent shall
not act as agent for such holders) in accordance  with the terms and  conditions
hereof,  and the Rights Agent hereby accepts such  appointment.  The Company may
from time to time  appoint  such Co- Rights  Agents as it may deem  necessary or

Rights  Agent shall have no duty to  supervise,  and shall in no event be liable

                  Section 3.        Issue of Rights Certificates.

                  (a)  Until  the  Distribution  Date,  (x) the  Rights  will be
evidenced  (subject to the provisions of paragraph (b) of this Section 3) by the
certificates  for Common  Stock  registered  in the names of the  holders of the
Common  Stock  and not by  separate  certificates,  and (y) the  Rights  will be
transferable  only in connection  with the transfer of the underlying  shares of
Common Stock (including a transfer to the Company). As soon as practicable after
the  Distribution  Date,  the Rights  Agent will 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 (other than any Person referred to in the
first  sentence of Section  7(e)),  at the  address of such holder  shown on the
records of the Company,  one or more Rights  Certificates,  evidencing one Right
for each  share of Common  Stock so held,  subject  to  adjustment  as  provided
herein.  In the event  that an  adjustment  in the number of Rights per share of
Common  Stock has been made  pursuant to Section  11(p)  hereof,  at the time of
distribution  of the Rights  Certificates,  the Company shall make the necessary
and appropriate  rounding  adjustments (in accordance with Section 14(a) hereof)
so that  Rights  Certificates  representing  only  whole  numbers  of Rights are
distributed and cash is paid in lieu of any fractional  Rights.  As of and after
the  Distribution  Date,  the Rights  will be  evidenced  solely by such  Rights
Certificates.

                  (b) As promptly as practicable  following the Record Date, the
Company  will send a copy of a Summary  of  Rights,  in  substantially  the form
attached  hereto as Exhibit C, by  first-class,  postage  prepaid  mail, to each
record holder of 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 Common  Stock  outstanding  as of the Record  Date,  until the
Distribution  Date  or  the  earlier  surrender  for  transfer  thereof  or  the
Expiration  Date,  the  Rights  associated  with  the  shares  of  Common  Stock
represented by such  certificates  shall be evidenced by such  certificates  for
Common Stock together with the Summary of Rights,  and the registered holders of
the Common Stock shall also be the registered  holders of the associated Rights.
Until the earlier of the Distribution  Date or the Expiration Date, the transfer
of any of the certificates for Common Stock outstanding on the Record Date, with
or without a copy of the Summary of Rights,  shall also  constitute the transfer
of the Rights associated with the Common Stock represented by such certificates.

                  (c) Rights  shall be issued in respect of all shares of Common
Stock that are issued (whether originally issued or delivered from the Company's
treasury)  after the Record  Date but prior to the  earlier of the  Distribution
Date or the Expiration Date or, in certain circumstances provided


                                       -8-


<PAGE>



in  Section  22  hereof,  after  the  Distribution  Date.   Certificates  issued
representing  such shares of Common  Stock that shall so become  outstanding  or
shall be transferred or exchanged after the Record Date but prior to the earlier
of the  Distribution  Date or the  Expiration  Date  shall  also be deemed to be
certificates for Rights, and shall bear the following legend:

                  This certificate also evidences and entitles the holder hereof
         to certain  Rights as set forth in the Rights  Agreement  between Kirby
         Corporation  (the  "Company")  and Fleet  National  Bank  (the  "Rights
         Agent")  dated  as of  July  18,  2000 as it may  from  time to time be
         supplemented  or amended (the "Rights  Agreement"),  the terms of which
         are hereby  incorporated  herein by reference and a copy of which is on
         file  at  the   principal   offices  of  the  Company.   Under  certain
         circumstances, as set forth in the Rights Agreement, such Rights may be
         redeemed, may be exchanged,  may expire or may be evidenced by separate
         certificates and will no longer be evidenced by this  certificate.  The
         Company  will  mail to the  holder  of this  certificate  a copy of the
         Rights Agreement,  as in effect on the date of mailing,  without charge
         promptly  after receipt of a written  request  therefor.  Under certain
         circumstances  set forth in the Rights Agreement,  Rights  beneficially
         owned  by or  transferred  to any  Person  who is,  was or  becomes  an
         Acquiring  Person or an Affiliate  or Associate  thereof (as such terms
         are defined in the Rights Agreement),  and certain transferees thereof,
         will become null and void and will no longer be transferable.

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of the Distribution  Date or the Expiration Date, the Rights  associated
with the Common Stock  represented  by such  certificates  shall be evidenced by
such  certificates  alone, and registered  holders of Common Stock shall also be
the registered holders of the associated Rights, and the transfer of any of such
certificates  shall also  constitute the transfer of the Rights  associated with
the Common Stock represented by such certificates.

                  Section 4.        Form of Rights Certificates.

                  (a) The  Rights  Certificates  (and the forms of  election  to
purchase and of assignment to be printed on the reverse  thereof),  when, as and
if issued,  shall be substantially in the form set forth in Exhibit B hereto and
may have such marks of identification or designation and such legends, summaries
or endorsements  printed thereon as the Company may deem  appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required to
comply with any  applicable  law or with any rule or  regulation  made  pursuant
thereto or with any rule or regulation of any stock exchange or quotation system
on which the Rights may from time to time be listed or quoted,  or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights
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  Fractional
Shares of Preferred  Stock as shall be set forth  therein at the price set forth
therein  (such  exercise  price per  Fractional  Share (or, as set forth in this
Agreement, for other securities), the "Purchase Price"), but the amount and type
of securities purchasable upon the exercise of each Right and the Purchase Price
thereof shall be subject to adjustment as provided herein.

                  (b) Any Rights  Certificate issued pursuant to Section 3(a) or
Section  22  hereof  that  represents  Rights  beneficially  owned  by a  Person
described  in the first  sentence of Section  7(e),  and any Rights  Certificate
issued  pursuant  to  Section 6 or Section 11 hereof  upon  transfer,  exchange,
replacement  or  adjustment  of any such  Rights,  shall  contain (to the extent
feasible) the following legend, modified as applicable to apply to such Person:

         The  Rights   represented  by  this  Rights  Certificate  are  or  were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate  or  Associate  of an Acquiring  Person (as such terms are
         defined in the Rights Agreement).  Accordingly, this Rights Certificate
         and the Rights represented hereby [will] [have] become null and void in
         the circumstances and with the effect specified in Section 7(e) of such
         Agreement.

The provisions of Section 7(e) of this Agreement  shall be operative  whether or
not the  foregoing  legend is  contained  on any such  Rights  Certificate.  The
Company shall give notice to the Rights Agent promptly after it becomes aware of
the existence of any Acquiring Person or any Associate or Affiliate thereof.

                  Section 5.        Countersignature and Registration.

                  (a) The Rights Certificates shall be executed on behalf of the
Company by its  Chairman  of the Board,  its  President  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 Rights  Certificates shall be countersigned by the Rights Agent,
either  manually  or by  facsimile  signature,  and  shall  not be valid for any
purpose  unless so  countersigned.  In case any officer of the Company who shall
have signed any of the Rights Certificates shall cease to be such officer of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such Rights Certificates, nevertheless, may be countersigned by the
Rights  Agent and issued and  delivered  by the Company  with the same force and
effect as though the person who signed such Rights  Certificates  had not ceased
to be such officer of the Company;  and any Rights  Certificate may be signed on
behalf of the Company by any person who, at the actual date of the  execution of
such Rights  Certificate,  shall be a proper officer of the Company to sign such
Rights  Certificate,  although  at 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 principal  office or offices  designated as the
appropriate  place  for  surrender  of  Rights  Certificates  upon  exercise  or
transfer,  books for registration and transfer of the Rights Certificates issued
hereunder.  Such books  shall  show the names and  addresses  of the  respective
holders of the Rights  Certificates,  the number of Rights evidenced on its face
by each of the Rights  Certificates  and the certificate  number and the date of
each of the Rights Certificates.

                  Section 6.  Transfer,  Split-Up,  Combination  and Exchange of
Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

                  (a) Subject to the  provisions of Section 4(b),  Section 7(e),
Section 13(d),  Section 14 and Section 24 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,  any Rights  Certificate  or Rights  Certificates  may be
transferred,  split up, combined or exchanged for another Rights  Certificate or
Rights  Certificates,  entitling the registered holder to purchase a like number
of  Fractional  Shares of Preferred  Stock (or,  following a  Triggering  Event,
Common Stock, other securities, cash or other assets, as the case may be) as the
Rights Certificate or Rights Certificates  surrendered then entitled such holder
(or former holder in the case of a transfer) to purchase.  Any registered holder
desiring to transfer,  split up,  combine or exchange any Rights  Certificate or
Rights  Certificates  shall make such request in writing delivered to the Rights
Agent, and shall surrender the Rights  Certificate or Rights  Certificates to be
transferred,  split up, combined or exchanged at the principal office or offices
of the Rights Agent  designated  for such purpose.  Neither the Rights Agent nor
the Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered  Rights Certificate until the registered holder
shall  have  completed  and  signed  the  certificate  contained  in the form of
assignment  on the  reverse  side of such  Rights  Certificate  and  shall  have
provided such  additional  evidence of the identity of the Beneficial  Owner (or
former Beneficial  Owner) thereof or of the Affiliates or Associates  thereof as
the Company shall reasonably request.  Thereupon the Rights Agent shall, subject
to Section 4(b), Section 7(e), Section 13(d),  Section 14 and Section 24 hereof,
countersign and deliver to the Person entitled  thereto a Rights  Certificate or
Rights  Certificates,  as the case may be,  as so  requested.  The  Company  may
require  payment  by  the  holder  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 Rights 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 Rights 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  Rights
Certificate  if mutilated,  the Company will,  subject to Section 4(b),  Section
7(e), Section 13(d), Section 14 and Section 24, execute and deliver a new Rights
Certificate of like tenor to the Rights Agent for  countersignature and delivery
to the  registered  owner in lieu of the  Rights  Certificate  so lost,  stolen,
destroyed or mutilated.

                  Section 7.        Exercise of Rights; Purchase Price.

                  (a) Subject to Section 7(e) hereof,  the registered  holder of
any Rights  Certificate  may exercise the Rights  evidenced  thereby  (except as
otherwise  provided herein including,  without  limitation,  the restrictions on
exercisability  set forth in Section 9(c),  Section 11(a)(iii) and Section 23(a)
hereof)  in  whole or in part at any  time  after  the  Distribution  Date  upon
surrender of the Rights  Certificate,  with the form of election to purchase and
the certificate on the reverse side thereof duly completed and executed,  to the
Rights Agent at the principal  office or offices of the Rights Agent  designated
for such purpose,  together with payment of the  aggregate  Purchase  Price with
respect to the total number of  Fractional  Shares of Preferred  Stock (or other
securities, cash or other assets, as


                                      -11-


<PAGE>



the case may be) as to which such surrendered Rights are then exercisable, at or
prior to the Expiration Date.

                  (b) The Purchase Price for each Fractional  Share of Preferred
Stock  pursuant to the exercise of a Right shall  initially be $92, and shall be
subject to  adjustment  from time to time as  provided  in Sections 11 and 13(a)
hereof and shall be payable in accordance with paragraph (c) below.

                  (c)  Upon  receipt  of  a  Rights   Certificate   representing
exercisable Rights, with the form of election to purchase and the certificate on
the reverse side thereof duly executed,  accompanied by payment, with respect to
each Right so exercised, of the Purchase Price per Fractional Share of Preferred
Stock (or other shares, securities, cash or other assets, as the case may be) to
be purchased as set forth below and an amount equal to any  applicable  transfer
tax, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly
(i)(A)  requisition from any transfer agent of the shares of Preferred Stock (or
make  available,  if the Rights  Agent is the  transfer  agent for such  shares)
certificates for the total number of Fractional  Shares of Preferred Stock to be
purchased,  and the Company hereby irrevocably  authorizes its 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 with a depositary  agent,  requisition from the
depositary agent depositary  receipts  representing  interests in such number of
Fractional  Shares 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  will  direct the  depositary  agent to comply with such  request,  (ii)
requisition  from the Company the amount of cash,  if any, to be paid in lieu of
fractional  shares in accordance with Section 14 hereof,  (iii) 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 Rights  Certificate,  registered
in such name or names as may be designated by such holder and (iv) after receipt
thereof,  deliver  such  cash,  if any,  to or upon the order of the  registered
holder of such Rights  Certificate.  The payment of the Purchase  Price (as such
amount may be reduced pursuant to Section 11(a)(iii) hereof) may be made in cash
or by certified check, cashier's or official bank check or bank draft payable to
the order of the Company or the Rights  Agent.  In the event that the Company is
obligated to issue other securities (including Common Stock) of the Company, pay
cash and/or distribute other property pursuant to Section 11(a) or Section 13(a)
hereof,  the Company  will make all  arrangements  necessary  so that such other
securities,  cash and/or other  property are available for  distribution  by the
Rights Agent, if and when appropriate. The Company reserves the right to require
prior to the occurrence of a Triggering  Event that, upon exercise of Rights,  a
number of Rights be exercised so that only whole shares of Preferred Stock would
be issued.

                  (d) In case the  registered  holder of any Rights  Certificate
shall  exercise  fewer  than all the  Rights  evidenced  thereby,  a new  Rights
Certificate  evidencing  Rights  equivalent to the Rights remaining  unexercised
shall be issued by the Rights Agent and  delivered to, or upon the order of, the
registered holder of such Rights  Certificate,  registered in such name or names
as may be  designated  by such holder,  subject to the  provisions of Section 14
hereof.

                  (e) Notwithstanding   anything  in  this   Agreement   to  the
contrary,  from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by or transferred to (i) an


                                      -12-


<PAGE>



Acquiring  Person or an Associate or Affiliate of an Acquiring Person other than
any such Person that became such pursuant to a Permitted Offer and a majority of
the  Continuing  Directors in good faith  determines was not involved in and did
not cause or facilitate,  directly or indirectly,  such Triggering Event, (ii) a
direct or indirect  transferee of such Rights from such Acquiring Person (or any
such  Associate or  Affiliate)  who becomes a transferee  after such  Triggering
Event or (iii) a direct or indirect  transferee of such Acquiring  Person (or of
any  such  Associate  or  Affiliate)  who  becomes  a  transferee  prior  to  or
concurrently  with such  Triggering  Event and receives such Rights  pursuant to
either (A) a transfer  (whether or not for  consideration)  from such  Acquiring
Person (or such  Affiliate or Associate) to holders of equity  interests in such
Acquiring  Person (or such  Affiliate or  Associate)  or to any Person with whom
such  Acquiring  Person (or such  Affiliate  or  Associate)  has any  continuing
agreement,  arrangement or understanding regarding the transferred Rights or (B)
a transfer that the Board of Directors of the Company  determines (or a majority
of the  Continuing  Directors  determines)  is part of a  plan,  arrangement  or
understanding  that has as a primary  purpose  or effect the  avoidance  of this
Section 7(e),  shall become null and void without any further action,  no holder
of such Rights  shall have any rights  whatsoever  with  respect to such Rights,
whether  under any  provision of this  Agreement or  otherwise,  and such Rights
shall not be  transferable.  The  Company  shall use all  reasonable  efforts to
ensure that the  provisions  of this  Section  7(e) and Section  4(b) hereof are
complied with, but shall have no liability to any holder of Rights  Certificates
or other  Person  as a result of its  failure  to make any  determinations  with
respect to an Acquiring  Person or its  Affiliates,  Associates  or  transferees
hereunder.

                  (f)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  neither  the  Rights  Agent nor the  Company  shall be  obligated  to
undertake any action with respect to a registered  holder upon the occurrence of
any  purported  exercise as set forth in this  Section 7 unless such  registered
holder shall have (i) completed and signed the certificate contained in the form
of election to purchase set forth on the reverse side of the Rights  Certificate
surrendered for such exercise and (ii) provided 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   Rights
Certificates.  All Rights Certificates  surrendered for the purpose of exercise,
transfer, split-up, combination or exchange shall, if surrendered to the Company
or 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 Rights  Certificates  shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Agreement.  The Company shall deliver
to the Rights Agent for cancellation and retirement,  and the Rights Agent shall
so cancel and retire, any other Rights Certificate  purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all  canceled  Rights  Certificates  to the  Company,  or shall,  at the written
request of the Company,  destroy such canceled Rights Certificates,  and in such
case shall deliver a certificate of destruction thereof to the Company.

                  Section 9.      Reservation and Availability of Capital Stock.

                  (a) The Company  covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares, or out of
its authorized  and issued shares held in its treasury,  the number of shares of
Preferred Stock (and, following the occurrence of a Triggering


                                      -13-


<PAGE>



Event,  Common  Stock  and/or  other  securities)  that,  as  provided  in  this
Agreement, including Section 11(a)(iii) hereof, will be sufficient to permit the
exercise in full of all outstanding Rights.

                  (b) So long as any shares of Preferred  Stock (and,  following
the  occurrence  of a Triggering  Event,  Common Stock and/or other  securities)
issuable  and  deliverable  upon the  exercise  of the  Rights are listed on any
national  securities exchange or quoted on any trading system, the Company shall
use its best  efforts to cause,  from and after  such time as the Rights  become
exercisable,  all  shares  reserved  for  such  issuance  to be  listed  on such
exchange,  or quoted on such system,  upon official notice of issuance upon such
exercise.  Following the occurrence of a Triggering  Event, the Company will use
its best  efforts  to list (or  continue  the  listing  of) the  Rights  and the
securities  issuable and  deliverable  upon the exercise of the Rights on one or
more  national  securities  exchanges or to cause the Rights and the  securities
purchasable  upon  exercise of the Rights to be reported by NASDAQ or such other
transaction reporting system then in use.

                  (c) The Company  shall use its best efforts to (i) prepare and
file, as soon as practicable  following the first  occurrence of a Flip-In Event
or, if applicable,  as soon as practicable following the earliest date after the
first  occurrence of a Flip-In Event on which the  consideration to be delivered
by the Company upon exercise of the Rights has been determined  pursuant to this
Agreement   (including  in  accordance  with  Section   11(a)(iii)   hereof),  a
registration  statement on an  appropriate  form under the  Securities  Act with
respect to the securities  purchasable  upon exercise of the Rights,  (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  earlier  of (A) the  date  as of  which  the  Rights  are no  longer
exercisable  for such  securities and (B) the Expiration  Date. The Company will
also take such action as may be appropriate under, or to ensure compliance with,
the securities or "blue sky" laws of the various  states in connection  with the
exercisability of the Rights. The Company may temporarily  suspend, for a period
of time not to  exceed 90 days  after  the date set  forth in clause  (i) of the
first sentence of this Section 9(c), the  exercisability  of the Rights in order
to  prepare  and file  such  registration  statement  and  permit  it to  become
effective.  In addition,  if the Company shall determine that the Securities Act
requires an effective  registration statement under the Securities Act following
the Distribution Date, the Company may temporarily suspend the exercisability of
the Rights until such time as such a  registration  statement  has been declared
effective.  Upon  any  such  suspension,   the  Company  shall  issue  a  public
announcement  stating that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement at such time as the suspension is no
longer  in  effect.  Notwithstanding  any  provision  of this  Agreement  to the
contrary,  the  Rights  shall  not be  exercisable  in any  jurisdiction  if the
requisite  qualification in such jurisdiction shall not have been obtained,  the
exercise  thereof shall not be permitted  under  applicable  law or any required
registration statement shall not have been declared effective.

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

                  (e) The Company further  covenants and agrees that it will pay
when due and payable any and all  federal and state  transfer  taxes and charges
that may be  payable  in  respect  of the  issuance  or  delivery  of the Rights
Certificates  and of any  certificates  for a number  of  Fractional  Shares  of
Preferred  Stock (or Common Stock and/or other  securities,  as the case may be)
upon the exercise of Rights. The Company shall not, however,  be required to pay
any  transfer  tax that may be payable in respect of any transfer or delivery of
Rights  Certificates  to a Person  other than,  or the issuance or delivery of a
number of  Fractional  Shares of  Preferred  Stock (or Common Stock and/or other
securities,  as the case may be) in  respect  of a name  other than that of, the
registered holder of the Rights  Certificates  evidencing Rights surrendered for
exercise  or to issue or deliver  any  certificates  for a number of  Fractional
Shares of Preferred Stock (or Common Stock and/or other securities,  as the case
may be) in a name other than that of the registered  holder upon the exercise of
any Rights  until  such tax shall have been paid (any such tax being  payable by
the holder of such Rights  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 in whose
name any  certificate  for a number of Fractional  Shares of Preferred Stock (or
Common  Stock and/or  other  securities,  as the case may be) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of such shares  (fractional  or otherwise) of Preferred  Stock (or Common
Stock and/or other securities,  as the case may be) represented  thereby on, and
such  certificate  shall be dated,  the date upon which the  Rights  Certificate
evidencing  such Rights was duly  surrendered  and payment of the Purchase Price
(and all 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
Common Stock and/or other securities,  as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares  (fractional  or  otherwise)  on, and such  certificate  shall be
dated, the next succeeding  Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are open. Prior to the exercise of the Rights evidenced thereby, the holder of a
Rights  Certificate,  as  such,  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 and Kind of
Shares or Number of Rights. The Purchase Price, the number and kind of shares or
other securities  subject to purchase upon exercise of each Right and the number
of Rights outstanding are subject to adjustment from time to time as provided in
this Section 11.

                           (a)(i)  In the event  the  Company  shall at any time
         after the Rights  Dividend  Declaration  Date (A) declare a dividend on
         the  outstanding  shares  of  Preferred  Stock  payable  in  shares  of
         Preferred  Stock,  (B)  subdivide the  outstanding  shares of Preferred
         Stock,  (C) combine the  outstanding  shares of Preferred  Stock into a
         smaller number of shares or (D) otherwise  reclassify  the  outstanding
         shares of  Preferred  Stock  (including  any such  reclassification  in
         connection with a  consolidation  or merger in which the Company is the
         continuing or surviving  corporation),  except as otherwise provided in
         this  Section  11(a) and Section 7(e)  hereof,  the  Purchase  Price in
         effect at the time of the record date for such


                                      -15-


<PAGE>



         dividend or of the effective date of such  subdivision,  combination or
         reclassification,  and the number and kind of shares of Preferred Stock
         or capital stock or other  securities,  as the case may be, issuable on
         such date, shall be proportionately  adjusted so that the holder of any
         Right  exercised  after such time shall be entitled  to  receive,  upon
         payment of the Purchase Price then in effect,  the aggregate number and
         kind of shares of Preferred Stock or capital stock or other securities,
         as the case may be, 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,  he would have owned upon such exercise
         and been entitled to receive by virtue of such  dividend,  subdivision,
         combination or reclassification.  If an event occurs that would require
         an adjustment  under both this Section  11(a)(i) and Section  11(a)(ii)
         hereof,  the adjustment  provided for in this Section 11(a)(i) shall be
         in  addition  to, and shall be made prior to, any  adjustment  required
         pursuant to Section 11(a)(ii) hereof.

                           (ii) Subject to Sections 23 and 24 of this Agreement,
         in the event any Person  shall,  at any time after the Rights  Dividend
         Declaration Date, become an Acquiring Person,  unless the event causing
         such Person to become an Acquiring  Person is (1) a Flip- Over Event or
         (2) an  acquisition  of shares of Common Stock  pursuant to a Permitted
         Offer  (provided  that this  clause  (2)  shall  cease to apply if such
         Acquiring  Person  thereafter  becomes  the  Beneficial  Owner  of  any
         additional shares of Common Stock other than pursuant to such Permitted
         Offer or a  transaction  set forth in Section  13(a) or 13(d)  hereof),
         then, promptly following the occurrence of such event, (x) the Purchase
         Price shall be adjusted to be the Purchase Price  immediately  prior to
         the first  occurrence  of a Flip-In  Event  multiplied by the number of
         Fractional  Shares of Preferred Stock for which a Right was exercisable
         immediately  prior to such first  occurrence  and (y) each  holder of a
         Right (except as provided  below in Section  11(a)(iii)  and in Section
         7(e) hereof) shall thereafter have the right to receive,  upon exercise
         thereof at a price equal to the Purchase  Price in accordance  with the
         terms of this  Agreement,  in lieu of the  shares  of  Preferred  Stock
         otherwise purchasable thereunder, such number of shares of Common Stock
         of the  Company as shall  equal the result  obtained  by  dividing  the
         Purchase  Price by 50% of the Current  Market Price per share of Common
         Stock on the date of such first occurrence (such number of shares,  the
         "Adjustment  Shares");  provided that the Purchase Price and the number
         of  Adjustment  Shares  shall be further  adjusted  as provided in this
         Agreement to reflect any events  occurring after the date of such first
         occurrence.

                           (iii) In the  event  that the  number  of  shares  of
         Common  Stock  that are  authorized  by the  Company's  certificate  of
         incorporation but not outstanding or reserved for issuance for purposes
         other than upon exercise of the Rights is not  sufficient to permit the
         exercise  in  full of the  Rights  in  accordance  with  the  foregoing
         subparagraph  (ii) of this Section  11(a),  the Company  shall,  to the
         extent  permitted by applicable law and  regulation,  (A) determine the
         excess  of (1) the value of the  Adjustment  Shares  issuable  upon the
         exercise of a Right  (computed  using the Current  Market Price used to
         determine the number of Adjustment  Shares) (the "Current  Value") over
         (2) the  Purchase  Price  (such  excess  is herein  referred  to as the
         "Spread"),  and (B) with respect to each Right, make adequate provision
         to  substitute  for the  Adjustment  Shares,  upon the  exercise of the
         Rights and payment of the applicable  Purchase  Price,  (1) cash, (2) a
         reduction  in the  Purchase  Price,  (3) Common  Stock or other  equity
         securities of the Company (including,  without  limitation,  shares, or
         units of


                                      -16-


<PAGE>



         shares,  of  preferred  stock  (including,   without  limitation,   the
         Preferred  Stock)  that  the  Board of  Directors  of the  Company  has
         determined  to have the same  value as  shares of  Common  Stock  (such
         shares of  preferred  stock are herein  referred  to as  "Common  Stock
         Equivalents")), (4) debt securities of the Company, (5) other assets or
         (6) any  combination of the foregoing,  having an aggregate value equal
         to the Current Value, where such aggregate value has been determined by
         the  Board of  Directors  of the  Company  based  upon the  advice of a
         nationally  recognized investment banking firm selected by the Board of
         Directors of the Company;  provided,  however, if the Company shall not
         have made adequate  provision to deliver  value  pursuant to clause (B)
         above within 30 days following the later of (x) the first occurrence of
         a  Flip-In  Event  and (y) the date on  which  the  Company's  right of
         redemption  pursuant to Section 23(a) expires (the later of (x) and (y)
         being  referred  to herein as the  "Flip- In Trigger  Date"),  then the
         Company shall be obligated to deliver,  upon the surrender for exercise
         of a Right and without requiring payment of the Purchase Price,  shares
         of Common Stock (to the extent available) and then, if necessary, cash,
         which shares  and/or cash have an aggregate  value equal to the Spread.
         If the Board of Directors of the Company shall  determine in good faith
         that it is likely that  sufficient  additional  shares of Common  Stock
         could be  authorized  for issuance upon exercise in full of the Rights,
         the  30-day  period  set forth  above  may be  extended  to the  extent
         necessary,  but not more than 90 days after the Flip- In Trigger  Date,
         in  order  that  the  Company  may seek  stockholder  approval  for the
         authorization  of such  additional  shares (such  period,  as it may be
         extended, the "Substitution Period"). To the extent that the Company or
         the  Board of  Directors  determines  that  some  action  need be taken
         pursuant  to  the  first  and/or  second   sentences  of  this  Section
         11(a)(iii),  the Company  (x) shall  provide,  subject to Section  7(e)
         hereof,  that such action  shall  apply  uniformly  to all  outstanding
         Rights,  and (y) may suspend the exercisability of the Rights until the
         expiration   of  the   Substitution   Period   in  order  to  seek  any
         authorization  of additional  shares  and/or to decide the  appropriate
         form of  distribution to be made pursuant to such first sentence and to
         determine the value thereof.  In the event of any such suspension,  the
         Company   shall   issue  a  public   announcement   stating   that  the
         exercisability of the Rights has been temporarily suspended, as well as
         a public  announcement  at such time as the  suspension is no longer in
         effect.  For  purposes  of this  Section  11(a)(iii),  the value of the
         Common Stock shall be the Current  Market Price per share of the Common
         Stock on the  Flip-In  Trigger  Date and the value of any Common  Stock
         Equivalent  shall be deemed to have the same value as the Common  Stock
         on such date.

                  (b) In case  the  Company  shall  fix a  record  date  for the
issuance  of rights,  options or  warrants  to all  holders of  Preferred  Stock
entitling  them to subscribe  for or purchase (for a period  expiring  within 45
calendar  days  after  such  record  date)  Preferred  Stock (or  shares  having
substantially  the same  rights,  privileges  and  preferences  as the shares of
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  price
per  share,  if a  security  convertible  into  Preferred  Stock  or  Equivalent
Preferred Stock) less than the Current Market Price per share of Preferred Stock
on such record date,  the Purchase  Price to be in effect after such record date
shall be  determined by  multiplying  the Purchase  Price in effect  immediately
prior to such  record date by a fraction,  the  numerator  of which shall be the
number of shares of Preferred  Stock  outstanding on such record date,  plus the
number of shares of Preferred  Stock that the  aggregate  offering  price of the
total number of shares of Preferred Stock and/or


                                      -17-


<PAGE>



Equivalent  Preferred  Stock so to be  offered  (and/or  the  aggregate  initial
conversion price of the convertible  securities so to be offered) would purchase
at such Current Market Price,  and the  denominator of which shall be the number
of shares of Preferred Stock 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 by  delivery  of  consideration,  part or all of which  may be in a form
other than cash, the value of such consideration  shall be as determined in good
faith by the Board of  Directors of the Company,  whose  determination  shall be
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and the holders of the Rights.  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 that would  then be in effect if such  record  date had not been
fixed.

                  (c)  In  case  the  Company  shall  fix a  record  date  for 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  quarterly cash dividend out of the 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
subscription  rights or warrants  (excluding  those referred to in Section 11(b)
hereof),  the  Purchase  Price to be in effect  after such  record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction,  the  numerator of which shall be the Current  Market
Price per share of  Preferred  Stock on such record  date,  less the fair market
value (as  determined  in good faith by the Board of  Directors  of the Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent and shall be  binding  on the  Rights  Agent) of the  portion of the cash,
assets or evidences of indebtedness so to be distributed or of such subscription
rights or warrants  applicable to a share of Preferred Stock and the denominator
of which shall be such Current Market Price per 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 be
adjusted to be the Purchase  Price that would have been in effect if such record
date had not been fixed.

                  (d)(i) For the  purpose of any  computation  hereunder,  other
than  computations  made  pursuant to Section  11(a)(iii)  hereof,  the "Current
Market  Price" per share of Common Stock of a Person on any date shall be deemed
to be the average of the daily Closing Prices per share of such Common Stock for
the 30 consecutive Trading Days immediately prior to such date, and for purposes
of computations made pursuant to Section  11(a)(iii) hereof, the "Current Market
Price" per share of Common  Stock on any date shall be deemed to be the  average
of the  daily  Closing  Prices  per  share  of  such  Common  Stock  for  the 10
consecutive  Trading Days immediately  following such date;  provided,  however,
that in the event that the  Current  Market  Price per share of Common  Stock is
determined  during a period  following  the  announcement  of (A) a dividend  or
distribution  on such Common Stock other than a regular  quarterly cash dividend
or  the  dividend  of  the  Rights,  or  (B)  any  subdivision,  combination  or
reclassification  of such  Common  Stock,  and the  ex-dividend  date  for  such
dividend or distribution,  or the record date for such subdivision,  combination
or  reclassification,  shall not have occurred prior to the  commencement of the
requisite 30 Trading Day or 10 Trading Day


                                      -18-


<PAGE>



period,  as set forth above,  then,  and in each such case,  the Current  Market
Price shall be properly adjusted to take into account  ex-dividend  trading.  If
the  Common  Stock is not  publicly  held or not 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 of the Company,  whose  determination shall
be described in a statement  filed with the Rights Agent and shall be conclusive
for all purposes.

                  (ii)  For  the  purpose  of  any  computation  hereunder,  the
"Current Market Price" per share (or Fractional  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(d) (other than the last sentence thereof).  If the
Current Market Price per share (or Fractional  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(d),  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  Agreement)  multiplied by the Current Market Price per share of the Common
Stock.  If neither the Common Stock nor the Preferred  Stock is publicly held or
so listed or traded, Current Market Price per share of the Preferred Stock shall
mean the fair  value  per  share as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent and shall be conclusive  for all  purposes.  For all
purposes of this  Agreement,  the Current Market Price of a Fractional  Share of
Preferred  Stock  shall be equal to the  Current  Market  Price of one  share of
Preferred Stock divided by 100.

                  (e)  Anything  herein  to  the  contrary  notwithstanding,  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  that by  reason of this  Section  11(e) are not
required  to be made shall be  carried  forward  and taken  into  account in any
subsequent  adjustment.  All calculations under this Section 11 shall be made to
the nearest cent or to the nearest  ten-thousandth of a share of Common Stock or
other share or to the nearest  ten-thousandth of a Fractional Share of Preferred
Stock,  as the case may be.  Notwithstanding  the first sentence of this Section
11(e),  any  adjustment  required by this Section 11 shall be made no later than
the earlier of (i) three years from the date of the  transaction  which mandates
such adjustment or (ii) the Expiration Date.

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

                  (g) All Rights originally issued by the Company  subsequent to
any adjustment  made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase


                                      -19-


<PAGE>



Price, the number of Fractional  Shares of Preferred Stock purchasable from time
to time hereunder upon exercise of the Rights, all subject to further adjustment
as provided herein.

                  (h) Unless the Company  shall have  exercised  its election as
provided in Section 11(i) hereof,  upon each adjustment of the Purchase Price as
a result of the calculations  made in Sections 11(b) and (c) 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
Fractional   Shares  of  Preferred   Stock   (calculated   to  the  nearest  one
ten-thousandth of a Fractional Share) obtained by (i) multiplying (x) the number
of Fractional  Shares of Preferred Stock covered by a Right immediately prior to
this  adjustment by (y) 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.

                  (i)  The  Company  may  elect,  on or  after  the  date of any
adjustment of the Purchase  Price, to adjust the number of Rights in lieu of any
adjustment in the number of  Fractional  Shares of Preferred  Stock  purchasable
upon  the  exercise  of a  Right.  Each  of the  Rights  outstanding  after  the
adjustment  in the  number  of Rights  shall be  exercisable  for the  number of
Fractional  Shares  of  Preferred  Stock  for  which  a  Right  was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated  to the nearest  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
Rights  Certificates have been issued,  shall be at least 10 days later than the
date of the public  announcement.  If Rights Certificates have been issued, upon
each  adjustment  of the number of Rights  pursuant to this Section  11(i),  the
Company shall, as promptly as practicable, cause to be distributed to holders of
record  of  Rights   Certificates  on  such  record  date  Rights   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 Rights  Certificates  held by such holders
prior to the date of adjustment,  and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall  be  entitled  after  such  adjustment.   Rights  Certificates  so  to  be
distributed  shall be issued,  executed and countersigned in the manner provided
for herein (and may bear,  at the option of the Company,  the adjusted  Purchase
Price) and shall be  registered  in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.

                  (j)  Irrespective  of any adjustment or change in the Purchase
Price or the number of Fractional  Shares of Preferred  Stock  issuable upon the
exercise of the  Rights,  the Rights  Certificates  theretofore  and  thereafter
issued may continue to express the Purchase Price per  Fractional  Share and the
number  of  Fractional   Shares  that  were  expressed  in  the  initial  Rights
Certificates issued hereunder.

                  (k) Before  taking any action that would  cause an  adjustment
reducing  the  Purchase  Price  below the then par value,  if any, or the stated
capital of the number of Fractional Shares of


                                      -20-


<PAGE>



Preferred  Stock or of the number of shares of Common Stock or other  securities
issuable upon exercise of a Right,  the Company shall take any corporate  action
that may, in the opinion of its counsel,  be necessary in order that the Company
may  validly  and  legally  issue  fully paid and  nonassessable  such number of
Fractional Shares of Preferred Stock or such number of shares of Common Stock or
other securities at such adjusted Purchase Price.

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

                  (m)   Anything   in   this   Section   11  to   the   contrary
notwithstanding,  the Company  shall be entitled to make such  reductions in the
Purchase  Price,  in addition to those  adjustments  expressly  required by this
Section 11, as and to the extent that in their good faith  judgment the Board of
Directors of the Company  shall  determine to be advisable in order that any (i)
consolidation  or subdivision of the Preferred  Stock,  (ii) issuance wholly for
cash of any shares of  Preferred  Stock at less than the current  market  price,
(iii) issuance  wholly for cash of shares of Preferred  Stock or securities that
by their terms are  convertible  into or  exchangeable  for shares of  Preferred
Stock,  (iv) stock  dividends  or (v)  issuance  of rights,  options or warrants
referred to in this Section 11  hereafter  made by the Company to holders of its
Preferred Stock shall not be taxable to such stockholders.

                  (n) The Company covenants and agrees that it shall not, at any
time that there is an Acquiring  Person,  (i) consolidate with any other Person,
(ii) merge with or into or be acquired pursuant to a share exchange by any other
Person,  or (iii) sell, lease or transfer (or permit one or more Subsidiaries to
sell,   lease  or  transfer),   in  one  transaction  or  a  series  of  related
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  or  Persons,  if (x) at the  time of or  immediately  after  such
consolidation,  merger,  share exchange,  sale,  lease or transfer there are any
rights,  warrants or other instruments or securities of the Company or any other
Person outstanding or agreements,  arrangements or understandings in effect that
would substantially  diminish or otherwise eliminate the benefits intended to be
afforded by the Rights, (y) prior to,  simultaneously  with or immediately after
such  consolidation,  merger,  share  exchange,  sale,  lease or  transfer,  the
stockholders  or other  equity  owners of the Person who  constitutes,  or would
constitute,  the  "Principal  Party" for purposes of Section  13(a) hereof shall
have received a distribution of Rights previously owned by such Person or any of
its  Affiliates  or  Associates,   or  (z)  the  identity,  form  or  nature  of
organization  of  the  Principal  Party  (including,   without  limitation,  the
selection  of the  Person  that will be the  Principal  Party as a result of the
Company's entering into one or more  consolidations,  mergers,  share exchanges,
sales,  leases,  transfers  or  transactions  with  more than one  party)  would
preclude or limit the exercise of Rights or otherwise diminish  substantially or
eliminate the benefits intended to be afforded by the Rights.

<PAGE>



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

                  (p) Notwithstanding Section 3(c) hereof or any other provision
of this  Agreement to the  contrary,  in the event that the Company shall at any
time after the Rights Dividend  Declaration  Date and prior to the  Distribution
Date (i) declare a dividend on the outstanding shares of Common Stock payable in
shares of Common Stock,  (ii) subdivide the outstanding  shares of Common Stock,
(iii) combine the  outstanding  shares of Common Stock into a smaller  number of
shares or (iv)  otherwise  reclassify  the  outstanding  shares of Common  Stock
(including  any such  reclassification  in connection  with a  consolidation  or
merger in which the Company is the  continuing  or surviving  corporation),  the
number of Rights associated with each share of Common Stock then outstanding, or
issued or delivered thereafter with Rights, shall be proportionately adjusted so
that the number of Rights thereafter  associated with each share of Common Stock
following  any such event shall equal the result  obtained  by  multiplying  the
number of Rights associated with each share of Common Stock immediately prior to
such event by a fraction  (the  "Adjustment  Fraction"),  the numerator of which
shall be the total  number of shares  of Common  Stock  outstanding  immediately
prior to the  occurrence of the event and the  denominator of which shall be the
total number of shares of Common Stock  outstanding  immediately  following  the
occurrence  of such event.  In lieu of such  adjustment  in the number of Rights
associated  with one share of Common Stock,  the Company may elect to adjust the
number of Fractional  Shares of Preferred Stock purchasable upon the exercise of
one Right and the Purchase Price. If the Company makes such election, the number
of Rights associated with one share of Common Stock shall remain unchanged,  and
the number of Fractional  Shares of Preferred Stock purchasable upon exercise of
one Right and the Purchase Price shall be  proportionately  adjusted so that (i)
the number of Fractional  Shares of Preferred Stock purchasable upon exercise of
a Right  following  such  adjustment  shall  equal the  product of the number of
Fractional  Shares of  Preferred  Stock  purchasable  upon  exercise  of a Right
immediately prior to such adjustment  multiplied by the Adjustment  Fraction and
(ii) the Purchase Price following such adjustment shall equal the product of the
Purchase Price immediately prior to such adjustment multiplied by the Adjustment
Fraction.

                  Section 12.  Certificate of Adjusted  Purchase Price or Number
of Shares.  Whenever an  adjustment is made as provided in Section 11 or Section
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) mail a brief  summary  thereof  to each  registered  holder  of a Rights
Certificate (or, if prior to the Distribution Date, to each registered holder of
a certificate representing shares of Common Stock) in accordance with Section 26
hereof.  The  Rights  Agent  shall be fully  protected  in  relying  on any such
certificate and on any adjustment therein contained.

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

                  (a) In the event  that,  from and after the time an  Acquiring
Person  has  become  such,  directly  or  indirectly,   (x)  the  Company  shall
consolidate  with,  or merge with and into,  any other  Person,  and the Company
shall not be the continuing or surviving  corporation of such  consolidation  or
merger,  (y) any Person  shall  consolidate  with,  or merge  with or into,  the
Company,  and the Company shall be the  continuing or surviving  corporation  of
such consolidation or merger, or the Company shall be party to a share exchange,
and, in connection with such  consolidation or merger or share exchange,  all or
part of the  outstanding  shares  of  Common  Stock  shall  be  changed  into or
exchanged  for stock or other  securities  of the Company or any other Person or
cash or any other  property,  or (z) the Company shall sell,  lease or otherwise
transfer  (or one or more of its  Subsidiaries  shall sell,  lease or  otherwise
transfer),  in one  transaction or a series of related  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 Person or Persons (other
than  the  Company  or  any  wholly  owned  Subsidiary  of  the  Company  or any
combination  thereof in one or more transactions each of which complies (and all
of which  together  comply) with Section 11(o)  hereof),  then, and in each such
case (except as may be contemplated by Section 13(d) hereof),  proper  provision
shall be made so that:  (i) the  Purchase  Price  shall  be  adjusted  to be the
Purchase Price  immediately  prior to the first occurrence of a Triggering Event
multiplied  by the number of  Fractional  Shares of Preferred  Stock for which a
Right was exercisable  immediately prior to such first  occurrence;  (ii) on and
after the  Distribution  Date,  each  holder of a Right,  except as  provided in
Section  7(e)  hereof,  shall  thereafter  have the right to  receive,  upon the
exercise  thereof at the  Purchase  Price in  accordance  with the terms of this
Agreement,  in lieu of shares of Preferred Stock or Common Stock of the Company,
such number of validly  authorized  and issued,  fully paid,  nonassessable  and
freely  tradeable shares of Common Stock of the Principal Party (as such term is
hereinafter defined),  not subject to any liens,  encumbrances,  rights of first
refusal or other  adverse  claims,  as shall be equal to the result  obtained by
dividing the Purchase  Price by 50% of the Current Market Price per share of the
Common  Stock  of such  Principal  Party  on the  date of  consummation  of such
Flip-Over  Event;  provided that the Purchase  Price and the number of shares of
Common Stock of such Principal  Party issuable upon exercise of each Right shall
be  further  adjusted  as  provided  in this  Agreement  to  reflect  any events
occurring after the date of such first occurrence of a Triggering Event or after
the date of such Flip- Over Event,  as applicable;  (iii) such  Principal  Party
shall  thereafter be liable for, and shall assume,  by virtue of such  Flip-Over
Event, all the obligations and duties of the Company pursuant to this Agreement;
(iv) the term  "Company"  shall  thereafter be deemed to refer to such Principal
Party, it being  specifically  intended that the provisions of Section 11 hereof
shall apply only to such  Principal  Party  following the first  occurrence of a
Flip-Over Event; (v) such Principal Party shall take such steps (including,  but
not limited to, the  reservation of a sufficient  number of shares of its Common
Stock) in connection  with the  consummation  of any such  transaction as may be
necessary to assure that the provisions  hereof shall  thereafter be applicable,
as nearly  as  reasonably  may be, in  relation  to its  shares of Common  Stock
thereafter  deliverable upon the exercise of the Rights; and (vi) the provisions
of Section  11(a)(ii)  hereof shall be of no effect  following the occurrence of
any Flip-Over Event.

                  (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),  (A) 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  or  share
         exchange,  or, if there is more than one such  issuer,  the  issuer the
         Common Stock of which has the greatest  aggregate  market value, or (B)
         if no  securities  are so issued,  (x) the Person  that  survives  such
         consolidation  or is the other  party to the merger and  survives  such
         merger,  or,  if there is more than one such  Person,  the  Person  the
         Common Stock of which has the greatest aggregate market value or (y) if
         the Person  that is the other  party to the merger does not survive the
         merger,  the Person that does survive the merger (including the Company
         if it survives); and

                  (ii) in the case of any transaction described in clause (z) of
         the first  sentence  of Section  13(a),  the  Person  that is the party
         receiving  the  greatest   portion  of  the  assets  or  earning  power
         transferred  pursuant to such transaction or transactions,  or, if each
         Person that is a party to such transaction or transactions receives the
         same portion of the assets or earning power so  transferred,  or if the
         Person  receiving  the greatest  portion of the assets or earning power
         cannot be  determined,  the Person  the  Common  Stock of which has the
         greatest aggregate market value;

provided,  however, that in any such case, if the Common Stock of such Person is
not at such time and has not been continuously  over the preceding  twelve-month
period  registered  under Section 12 of the Exchange Act, and if (1) such Person
is a direct or indirect  Subsidiary of another  Person the Common Stock of which
is and has been so  registered,  "Principal  Party"  shall  refer to such  other
Person;  (2) such Person is a Subsidiary,  directly or indirectly,  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 (3) such Person is
owned, directly or indirectly,  by a joint venture formed by two or more Persons
that are not owned,  directly or indirectly,  by the same Person,  the rules set
forth in (1) and (2) 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  Flip-Over  Event
unless each  Principal  Party (or Person that may become a Principal  Party as a
result of such  Flip-Over  Event) shall have a sufficient  number of  authorized
shares of its Common Stock that 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 such  Principal  Party 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 such Flip-Over  Event,
the Principal Party at its own expense 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


                                      -24-


<PAGE>



         form,  and  will  use its  best  efforts  to  cause  such  registration
         statement  to (A) become  effective as soon as  practicable  after such
         filing and (B) 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;

                  (iii)  use  its  best  efforts,  if the  Common  Stock  of the
         Principal  Party is or shall  become  listed on a  national  securities
         exchange,  to list (or  continue  the  listing  of) the  Rights and the
         securities  purchasable  upon exercise of the Rights on such securities
         exchange and, if the Common Stock of the  Principal  Party shall not be
         listed on a national securities  exchange,  to cause the Rights and the
         securities  purchasable  upon  exercise of the Rights to be reported by
         NASDAQ or such other transaction reporting system then in use; and

                  (iv)  deliver to holders  of the Rights  historical  financial
         statements  for the  Principal  Party and each of its  Affiliates  that
         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 Flip-Over Event
shall occur at any time after the occurrence of a Flip-In Event, the Rights that
have not theretofore been exercised shall thereafter  become  exercisable in the
manner described in Section 13(a).

                  (d)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  Section 13 shall not be  applicable  to a  transaction  described  in
subparagraphs  (x)  and  (y)  of  Section  13(a)  if  (i)  such  transaction  is
consummated  with a Person or  Persons  who  acquired  shares  of  Common  Stock
pursuant to a Permitted  Offer (or a wholly owned  subsidiary of any such Person
or  Persons),  (ii)  the  price  per  share  of  Common  Stock  offered  in such
transaction  is not less than the price  per share of Common  Stock  paid to all
holders of Common Stock whose shares were  purchased  pursuant to such Permitted
Offer,  and (iii)  the form of  consideration  being  offered  to the  remaining
holders of shares of Common Stock  pursuant to such  transaction  is the same as
the  form  of  consideration   paid  pursuant  to  such  Permitted  Offer.  Upon
consummation of any such  transaction  contemplated  by this Section 13(d),  all
Rights hereunder shall expire.

                  Section 14.       Fractional Rights and Fractional Shares.

                  (a) The Company  shall not be required to issue  fractions  of
Rights,  except  prior to the  Distribution  Date as provided  in Section  11(p)
hereof,  or to distribute  Rights  Certificates or scrip  evidencing  fractional
Rights. In lieu of such fractional Rights, there shall be paid to the registered
holders of the Rights  Certificates  with regard to which such fractional Rights
would otherwise be issuable, an amount in cash equal to the same fraction of the
Closing Price of one Right for the Trading Day immediately  prior to the date on
which such fractional Rights would have been otherwise issuable.

<PAGE>



                  (b) The Company  shall not be required to issue  fractions  of
shares of  Preferred  Stock  (other  than,  except as provided  in Section  7(c)
hereof, fractions that are integral multiples of a Fractional Share of Preferred
Stock)  upon  exercise  of the  Rights or to  distribute  certificates  or scrip
evidencing  fractional shares of Preferred Stock (other than, except as provided
in Section 7(c) hereof,  fractions  that are integral  multiples of a Fractional
Share of Preferred  Stock).  Interests in fractions of shares of Preferred Stock
in integral  multiples  of a  Fractional  Share of  Preferred  Stock may, at the
election of the  Company in its sole  discretion,  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 a Fractional Share
of  Preferred  Stock,  the Company may pay to the  registered  holders of Rights
Certificates  at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of one  one-hundredth of the Closing Price of
a share of Preferred Stock for the Trading Day immediately  prior to the date of
such exercise.

                  (c)  Following  the  occurrence  of a  Triggering  Event,  the
Company shall not be required to issue  fractions of shares of Common Stock upon
exercise  of the  Rights  or to  distribute  certificates  or  scrip  evidencing
fractional shares of Common Stock. In lieu of fractional shares of Common Stock,
the Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the Closing  Price of one share of Common  Stock for the Trading Day
immediately prior to the date of such exercise.

                   (d) The  holder  of a Right by the  acceptance  of the  Right
expressly  waives his right to receive any  fractional  Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

                  Section 15. Rights of Action.  All rights of action in respect
of this  Agreement,  other  than  rights of action  vested in the  Rights  Agent
pursuant to Section 18 hereof,  are vested in the respective  registered holders
of the Rights  Certificates (and, prior to the Distribution Date, the registered
holders of the  Common  Stock)  and,  where  applicable,  the  Company;  and any
registered holder of any Rights 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 Rights  Certificate  (or,  prior to the  Distribution  Date, of the
Common Stock), may, in his own behalf and for his own benefit,  enforce, and may
institute  and maintain any suit,  action or  proceeding  against the Company to
enforce,  or  otherwise  act in  respect  of, his right to  exercise  the Rights
evidenced  by such  Rights  Certificate  in the manner  provided  in such Rights
Certificate  and in  this  Agreement.  Without  limiting  the  foregoing  or any
remedies  available to the holders of Rights,  it is  specifically  acknowledged
that the  holders  of Rights  would not have an  adequate  remedy at law for any
breach of this  Agreement and shall be entitled to specific  performance  of the
obligations  hereunder  and  injunctive  relief  against  actual  or  threatened
violations of the obligations hereunder of any Person subject to this Agreement.
After a  Triggering  Event,  holders of Rights  shall be entitled to recover the
reasonable costs and expenses,  including  attorneys' fees,  incurred by them in
any action to enforce the provisions of this Agreement.

                  Section 16. Agreement of Rights  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  not  be
evidenced by Rights  Certificates  and will be  transferable  only in connection
with the transfer of Common Stock;

                  (b) after the Distribution Date, the Rights  Certificates will
be transferable only on the registry books of the Rights Agent if surrendered at
the  principal  office  or  offices  of the  Rights  Agent  designated  for such
purposes,  duly endorsed or accompanied  by a proper  instrument of transfer and
with the form of  assignment  set  forth on the  reverse  side  thereof  and the
certificate contained therein duly completed and fully executed;

                  (c)  subject to Section  6(a) and  Section  7(f)  hereof,  the
Company  and the  Rights  Agent may deem and treat  the  Person in whose  name a
Rights  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
Rights  Certificates 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; and

                  (d)   notwithstanding   anything  in  this  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  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 use its best
efforts to have any such order, decree or ruling lifted or otherwise  overturned
as soon as possible.

                  Section   17.   Rights   Certificate   Holder   Not  Deemed  a
Stockholder.  No holder, as such, of any Rights Certificate shall be entitled to
vote, receive dividends or be deemed for any purpose the holder of the number of
Fractional Shares of Preferred Stock or any other securities of the Company that
may at any time be issuable upon the exercise of the Rights represented thereby,
nor shall anything contained herein or in any Rights Certificate be construed to
confer upon the holder of any Rights 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  Rights  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
disbursements and other reasonable  disbursements incurred in the administration
and execution of this  Agreement and the exercise and  performance of its duties
hereunder.  The Company  also agrees to  indemnify  the Rights Agent for, and to
hold it harmless against, any loss, liability or expense, incurred without gross
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection  with the  acceptance
and  administration  of this  Agreement,  including  the costs and  expenses  of
defending against any claim of liability in the premises.

                  (b) The Rights  Agent  shall be  protected  and shall incur no
liability  for or in respect of any action  taken,  suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate  or  certificate  for 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, after proper  inquiry or  examination,  to be
genuine and to be signed, executed and, where necessary, guaranteed, 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 or stock transfer business of the Rights Agent
or any successor Rights Agent,  shall be the successor to the Rights Agent under
this  Agreement  without the execution or filing of any paper or any further act
on the  part  of any  of  the  parties  hereto;  provided,  however,  that  such
corporation  would be eligible for appointment as a successor Rights Agent under
the provisions of Section 21 hereof.  In case at the time such successor  Rights
Agent shall succeed to the agency created by this  Agreement,  any of the Rights
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the  countersignature  of a predecessor  Rights Agent and
deliver such Rights Certificates so countersigned;  and in case at that time any
of the Rights  Certificates  shall not have been  countersigned,  any  successor
Rights Agent may countersign such Rights  Certificates either in the name of the
predecessor or in the name of the successor  Rights Agent; and in all such cases
such  Rights  Certificates  shall  have the full  force  provided  in the Rights
Certificates and in this Agreement.

                  (b) In case at any time the name of the Rights  Agent shall be
changed  and at  such  time  any of the  Rights  Certificates  shall  have  been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights  Certificates so  countersigned;  and in
case  at  that  time  any  of  the  Rights  Certificates  shall  not  have  been
countersigned,  the Rights Agent may countersign such Rights Certificates either
in its prior name or in its  changed  name;  and in all such  cases such  Rights
Certificates  shall have the full force provided in the Rights  Certificates and
in this Agreement.

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

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

                  (b)  Whenever  in the  performance  of its  duties  under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including,  without limitation, the identity of any Acquiring Person and
the  determination  of "Current  Market  Price") be proved or established by the
Company prior to taking or suffering any action  hereunder,  such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively  proved and established by a certificate  signed by
the Chairman of the Board, the President, any Vice President, the Treasurer, any
Assistant Treasurer, 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 Agreement in reliance upon such certificate.

                  (c) The Rights  Agent shall be liable  hereunder  only for its
own gross  negligence,  bad faith or willful  misconduct.  In no event shall the
Rights Agent be liable for special,  indirect or consequential loss or damage of
any kind  whatsoever  (including but not limited to lost  profits),  even if the
Rights  Agent has been  advised  of the  likelihood  of such loss or damage  and
regardless of the form of action.

                  (d) The Rights  Agent  shall not be liable for or by reason of
any of the statements of fact or recitals  contained in this Agreement or in the
Rights  Certificates  or be  required  to  verify  the  same  (except  as to its
countersignature  on such  Rights  Certificates),  but all such  statements  and
recitals are and shall be deemed to have been made by the Company only.

                  (e) The Rights Agent shall not be under any  responsibility in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or execution  of any Rights  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any adjustment  required under the provisions of
Section 11 or Section 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 Rights  Certificates  after receipt of actual knowledge 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 Common Stock or other  securities to be issued pursuant to
this  Agreement  or any  Rights  Certificate  or as to  whether  any  shares  of
Preferred Stock or Common Stock or other  securities  will,  when so 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 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 President, any 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.

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

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

                  (j) No provision of this  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 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise or transfer without first consulting with the Company.

                  Section 21.  Change of Rights  Agent.  The Rights Agent or any
successor  Rights Agent may resign and be discharged  from its duties under this
Agreement  upon 30 days' notice in writing  mailed to the  Company,  and to each
transfer  agent of the Common Stock and the  Preferred  Stock,  by registered or
certified  mail,  and  to  the  registered   holders,  if  any,  of  the  Rights
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor  Rights Agent (with or without cause) 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 the Preferred  Stock,  by registered
or certified mail, and to the registered holders of the Rights Certificates,  if
any, by

                                      -30-

<PAGE>


first-  class  mail.  If the Rights  Agent  shall  resign or be removed or shall
otherwise become  incapable of acting,  the Company shall appoint a successor to
the Rights Agent.  Notwithstanding the foregoing  provisions of this Section 21,
in no event  shall the  resignation  or removal of a Rights  Agent be  effective
until a successor  Rights Agent shall have been appointed and have accepted such
appointment.  If the Company shall fail to make such appointment within a period
of 30 days after giving  notice of such removal or after it has been notified in
writing of such  resignation  or incapacity  by the  resigning or  incapacitated
Rights Agent or by the  registered  holder of a Rights  Certificate  (who shall,
with such notice,  submit his Rights Certificate for inspection by the Company),
then the Rights Agent or the  registered  holder of any Rights  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 organized and doing business under the laws of
the United  States or of the States of New York or Texas (or of any other  state
of the United  States so long as such  corporation  is  authorized  to conduct a
stock transfer or corporate  trust business in the States of New York or Texas),
in good  standing,  which is  authorized  under such laws to exercise  corporate
trust or stock  transfer  powers and is subject to supervision or examination by
federal  or state  authority  and  which has at the time of its  appointment  as
Rights Agent a combined  capital and surplus of at least  $50,000,000  or (b) an
affiliate  of a  corporation  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 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 the
Preferred Stock, and mail a notice thereof in writing to the registered holders,
if any, of the Rights  Certificates.  Failure to give any notice provided for in
this Section 21, however,  or any defect therein,  shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

                  Section   22.    Issuance   of   New   Rights    Certificates.
Notwithstanding  any of the provisions of this Agreement or of the Rights to the
contrary,  the  Company  may,  at its  option,  issue  new  Rights  Certificates
evidencing  Rights in such form as may be approved by its Board of  Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other  securities  or property  purchasable  under the Rights
Certificates  made in  accordance  with the  provisions  of this  Agreement.  In
addition,  in  connection  with the  issuance or sale of shares of Common  Stock
following the  Distribution  Date and prior to the Expiration  Date, 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 plan or arrangement  granted
or  awarded  on or  prior  to the  Distribution  Date,  or  upon  the  exercise,
conversion  or exchange of  securities  issued by the Company on or prior to the
Distribution  Date,  and (b) may,  in any other  case,  if deemed  necessary  or
appropriate by the Board of Directors of the Company,  issue Rights Certificates
representing  the appropriate  number of Rights in connection with such issuance
or sale; provided,  however, that (i) no such Rights Certificate 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 Rights  Certificate would be issued,  and
(ii) no such Rights


                                      -31-


<PAGE>



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) The Board of  Directors of the Company may, at its option,
at any time prior to the  earlier of (i) the close of  business on the tenth day
following the first date of public  announcement  of the occurrence of a Flip-In
Event (or, if such date shall have occurred  prior to the Record Date, the close
of business on the tenth day following the Record Date) and (ii) the  Expiration
Date, cause the Company to redeem all but not less than all the then outstanding
Rights  at a  redemption  price  of  $0.01  per  Right,  as such  amount  may be
appropriately adjusted, if necessary, to reflect any stock split, stock dividend
or similar  transaction  occurring  after the Rights Dividend  Declaration  Date
(such redemption price being hereinafter referred to as the "Redemption Price");
provided,  however,  if  the  Board  of  Directors  of  the  Company  authorizes
redemption  of the Rights after the time a Person  becomes an Acquiring  Person,
the Rights may be redeemed only if (A) there is at least one Continuing Director
then in  office  and (B) the  Board  of  Directors,  with the  concurrence  of a
majority  of the  Continuing  Directors  then in  office,  determines  that such
redemption is, in their  judgment,  in the best interests of the Company and its
stockholders.  Notwithstanding  anything  contained  in  this  Agreement  to the
contrary,  the Rights shall not be exercisable  after the first  occurrence of a
Flip-In Event until such time as the Company's right of redemption hereunder has
expired.  The  Company  may, at its option,  pay the  Redemption  Price in cash,
shares of Common Stock (based on the Current Market Price of the Common Stock at
the time of redemption) or any other form of consideration deemed appropriate by
the Board of Directors.

                  (b) Immediately  upon the  effectiveness  of the action of the
Board of Directors of the Company  ordering  the  redemption  of the Rights (the
effectiveness  of which action may be  conditioned  on the  occurrence of one or
more events or on the existence of one or more facts or may be effective at some
future time), evidence of which shall be filed with the Rights Agent 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  for  each  Right so held.  Promptly  after  the
effectiveness of the action of the Board of Directors ordering the redemption of
the Rights, the Company shall give notice of such redemption to the Rights Agent
and the registered holders of the then outstanding Rights by mailing such notice
to all such  holders  at each  holder's  last  address  as it  appears  upon the
registry  books of the Rights Agent or, prior to the  Distribution  Date, on the
registry books of the Company for the Common Stock. Any notice that is mailed in
the manner  herein  provided  shall be deemed  given,  whether or not the holder
receives the notice.  Each such notice of  redemption  shall state the method by
which the payment of the Redemption Price will be made.

                  Section 24.       Exchange.

                  (a) If there  is at  least  one  Continuing  Director  then in
office,  the  Board of  Directors  of the  Company,  with the  concurrence  of a
majority of the Continuing  Directors then in office, may, at its option, at any
time and from time to time after the occurrence of a Flip-In Event, 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 shares of Common


                                      -32-


<PAGE>



Stock or Common Stock  Equivalents or any  combination  thereof,  at an exchange
ratio of one share of Common Stock,  or such number of Common Stock  Equivalents
or units  representing  fractions  thereof  as would be  deemed to have the same
value as one  share of Common  Stock,  per  Right,  appropriately  adjusted,  if
necessary,  to reflect any stock split,  stock  dividend or similar  transaction
occurring after the Rights Dividend  Declaration Date (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of  Directors  may not effect such  exchange at any time after (i) any
Person  (other  than  an  Exempt  Person),  together  with  all  Affiliates  and
Associates of such Person,  becomes the  Beneficial  Owner of 50% or more of the
shares of Common Stock then  outstanding  or (ii) the  occurrence of a Flip-Over
Event.

                  (b) Immediately  upon the  effectiveness  of the action of the
Board of Directors of the Company  ordering the exchange of any Rights  pursuant
to and in accordance with  subsection (a) of this Section 24 (the  effectiveness
of which action may be conditioned on the occurrence of one or more events or on
the  existence of one or more facts or may be effective at some future time) 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  and/or  Common Stock
Equivalents equal to the number of such Rights held by such holder multiplied by
the Exchange  Ratio.  The Company shall  promptly give public notice of any such
exchange;  provided,  however,  that the failure to give, or any defect in, such
notice  shall not affect the  validity of such  exchange.  The Company  promptly
shall mail a notice of any such  exchange  to all of the  registered  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 the shares of Common
Stock and/or  Common Stock  Equivalents  for Rights will be effected and, in the
event of any partial exchange, the number of Rights that will be exchanged.  Any
partial  exchange  shall be effected as nearly pro rata as possible based on the
number of Rights  (other  than  Rights  that have  become  void  pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights.

                  (c) In the event  that the  number  of shares of Common  Stock
that are  authorized  by the  Company's  certificate  of  incorporation  but not
outstanding  or reserved for issuance for purposes  other than upon  exercise of
the Rights is not sufficient to permit an exchange of Rights as  contemplated in
accordance  with this Section 24, the Company may, at its option,  take all such
action as may be necessary to  authorize  additional  shares of Common Stock for
issuance upon exchange of the Rights.

                  (d) The Company  shall not be required to issue  fractions  of
shares  of  Common  Stock or to  distribute  certificates  or  scrip  evidencing
fractional  shares of Common Stock upon exchange of the Rights.  In lieu of such
fractional  shares of Common  Stock,  the  Company  shall pay to the  registered
holders of Rights 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
value of a whole share of Common  Stock.  For  purposes of this  Section 24, the
value of a whole share of Common  Stock shall be the Closing  Price per share of
Common  Stock for the  Trading  Day  immediately  prior to the date of  exchange
pursuant to this Section 24, and the value of any Common Stock  Equivalent shall
be deemed to have the same value as the Common Stock on such date.

                  Section 25.       Notice of Certain Events.

                  (a) In case the Company shall  propose,  at any time after the
Distribution  Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred  Stock or to make any other  distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company),  or (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any  additional  shares
of  Preferred  Stock or shares  of stock of any  class or any other  securities,
rights or  options,  or (iii) to effect any  reclassification  of its  Preferred
Stock  (other  than  a  reclassification   involving  only  the  subdivision  of
outstanding  shares of Preferred  Stock), or (iv) to effect any consolidation or
merger into or with any other Person  (other than a wholly owned  Subsidiary  of
the Company in a transaction  that complies  with Section 11(o)  hereof),  or to
effect  any  sale,  lease  or other  transfer  of all or  substantially  all the
Company's  assets to any other  Person or  Persons  (other  than a wholly  owned
Subsidiary  of the Company in a  transaction  that  complies  with Section 11(o)
hereof),  or (v) to effect  the  liquidation,  dissolution  or winding up of the
Company, or (vi) to be acquired pursuant to a share exchange, then, in each such
case,  the Company shall give to each holder of record of a Rights  Certificate,
to the extent  feasible and 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,   lease,   transfer,
liquidation,  dissolution  or  winding  up is to  take  place  and  the  date of
participation  therein by the holders of the shares of Preferred  Stock,  if any
such date is to be fixed,  and such notice  shall be so given in the case of any
action  covered by clause (i) or (ii) above at least 20 days prior to the record
date for  determining  holders of the shares of Preferred  Stock for purposes of
such action, and in the case of any such other action, at least 20 days prior to
the date of the  taking of such  proposed  action  or the date of  participation
therein by the holders of the shares 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 any Flip-In Event or Flip-Over  Event shall occur,
then  (i) the  Company  shall  as soon as  practicable  thereafter  give to each
registered  holder  of a  Rights  Certificate  (or  if  occurring  prior  to the
Distribution  Date, the registered  holders of Common Stock), in 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(a)(ii) or Section  13(a)  hereof,  and (ii) all  references  in the preceding
paragraph to Preferred Stock shall be deemed thereafter to refer to Common Stock
and/or, if appropriate, other securities.

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

                  Attention: Client Administration

Notices  or  demands  authorized  by this  Agreement  to be given or made by the
Company or the Rights  Agent to the holder of any  Rights  Certificate  (or,  if
prior to the  Distribution  Date,  to the  holder of  certificates  representing
shares of Common  Stock) shall be  sufficiently  given or made if sent by first-
class mail,  postage  prepaid,  addressed  to such holder at the address of such

                  Section 27. Supplements and Amendments.  Except as provided in
the last  sentence  of this  Section  27, at any time when the  Rights  are then
redeemable,  the Company may in its sole and absolute  discretion and the Rights
Agent shall,  if the Company so directs,  supplement  or amend any  provision of
this  Agreement in any respect  without the approval of any holders of Rights or
holders of Common Stock. At any time when the Rights are not redeemable,  except
as  provided in the last  sentence  of this  Section 27, the Company may and the
Rights  Agent  shall,  if the  Company  so  directs,  supplement  or amend  this
Agreement without the approval of any holders of Rights in order (i) to cure any
ambiguity, (ii) to correct or supplement any provision contained herein that may
be defective or inconsistent with any other provisions herein,  (iii) to shorten
or  lengthen  any time  period  hereunder  or (iv) to change or  supplement  the
provisions  hereunder  in any manner  that the  Company  may deem  necessary  or
desirable;  provided  that no such  amendment  or  supplement  shall  materially
adversely affect the interests of the holders of Rights (other than an Acquiring
Person or an  Affiliate  or  Associate  of an  Acquiring  Person);  and  further
provided that this Agreement may not be supplemented or amended pursuant to this
sentence  to  lengthen  (A) a time  period  relating  to when the  Rights may be
redeemed or (B) any other time period unless the  lengthening of such other time
period is for the purpose of protecting,  enhancing or clarifying the rights of,
and/or the benefits to, the holders of Rights (other than any  Acquiring  Person
and its Affiliates and  Associates).  Upon the delivery of a certificate from an
appropriate  officer of the Company which states that the proposed supplement or
amendment is in  compliance  with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment;  provided,  however, that the Rights
Agent may, but shall not be  obligated  to,  enter into any such  supplement  or
amendment that affects the Rights Agent's own rights, duties or immunities under
this  Agreement.  Notwithstanding  anything  contained in this  Agreement to the
contrary,  (1) at any time after the time a Person becomes an Acquiring  Person,
this Agreement may be  supplemented or amended only if (A) there is at least one
Continuing  Director  then in office  and (B) the Board of  Directors,  with the
concurrence of a majority of the Continuing Directors then in office, determines
that such supplement or amendment is, in their  judgment,  in the best interests
of the Company and its stockholders, and (2) no supplement or amendment shall be
made that decreases the Redemption Price.

                  Section 28.  Successors.  All the covenants  and provisions of
this  Agreement  by or for the benefit of the Company or the Rights  Agent shall
bind and  inure  to the  benefit  of their  respective  successors  and  assigns
hereunder.

                  Section  29.  Determinations  and  Actions  by  the  Board  of
Directors,  etc.  For all purposes of this  Agreement,  any  calculation  of the
number of shares of Common Stock  outstanding at any particular time,  including
for purposes of determining the particular percentage of such outstanding shares
of Common Stock of which any Person is the  Beneficial  Owner,  shall be made in
accordance  with the last sentence of Rule  13d-3(d)(1)(i)  of the General Rules
and  Regulations  under  the  Exchange  Act as in  effect  on the  date  of this
Agreement.  The Board of  Directors  of the Company  (or,  as set forth  herein,
certain specified members thereof and, where  specifically  provided for herein,
the  concurrence  of a  majority  of the  Continuing  Directors)  shall have the
exclusive  power and authority to administer  this Agreement and to exercise all
rights and powers specifically  granted to the Board of Directors of the Company
(with, where specifically  provided for herein, the concurrence of a majority of
the Continuing Directors) or to the Company, or as may be necessary or advisable
in the  administration of this Agreement,  including,  without  limitation,  the
right and power to (i) interpret the  provisions of this Agreement and (ii) make
all determinations  deemed necessary or advisable for the administration of this
Agreement  (including,  without  limitation,  a  determination  to redeem or not
redeem the Rights or to amend this Agreement).  All such actions,  calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing)  that are done or made by the Board
of Directors of the Company (with, where  specifically  provided for herein, the
concurrence of a majority of the Continuing  Directors) in good faith, shall (x)
be final,  conclusive and binding on the Company,  the Rights Agent, the holders
of the Rights, as such, and all other parties,  and (y) not subject the Board of
Directors (or the  Continuing  Directors) to any liability to the holders of the
Rights.

                  Section  30.  Benefits  of  this  Agreement.  Nothing  in this
Agreement  shall be construed to give to any Person other than the Company,  the
Rights Agent and the registered  holders of the Rights  Certificates (and, prior
to the Distribution  Date,  registered holders of the Common Stock) any legal or
equitable right, remedy or claim under this Agreement;  but this Agreement shall
be for the sole and exclusive  benefit of the Company,  the Rights Agent and the
registered  holders of the Rights  Certificates  (and, prior to the Distribution
Date, registered holders of the Common Stock).

                  Section 31. Severability.  If any term, provision, covenant or
restriction  of this Agreement is held by a court of competent  jurisdiction  or
other  authority  to be invalid,  void or  unenforceable,  the  remainder of the
terms, provisions,  covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected,  impaired or invalidated;
provided,  however,  that  notwithstanding  anything  in this  Agreement  to the
contrary, if any such term,  provision,  covenant or restriction is held by such
court  or  authority  to be  invalid,  void or  unenforceable  and the  Board of
Directors of the Company (with the  concurrence  of a majority of the Continuing
Directors)  determines  in its good faith  judgment  that  severing  the invalid
language from this  Agreement  would  adversely  affect the purpose or effect of
this Agreement,  the right of redemption set forth in Section 23 hereof shall be
reinstated  and shall not expire  until the close of  business  on the tenth day
following  the  date of such  determination  by the  Board of  Directors  of the
Company.  Without  limiting the  foregoing,  if any provision  requiring  that a
determination  be made by less than the entire Board of Directors of the Company
is held by a court of competent jurisdiction or other authority to be


                                      -36-


<PAGE>



invalid,  void or unenforceable,  such  determination  shall then be made by the
entire Board of Directors of the Company.

                  Section 32. Governing Law. This Agreement, each Right and each
Rights  Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of Nevada and for all  purposes  shall be  governed by and
construed in accordance with the laws of such State applicable to contracts made
and to be performed entirely within such State.

                  Section 33.   Counterparts.  This Agreement may be executed in
any number of counterparts and each of such counterparts  shall for all purposes
be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

                  Section 34.  Descriptive Headings. Descriptive headings of the
several  Sections of this Agreement are inserted for convenience  only and shall
not  control or affect  the  meaning or  construction  of any of the  provisions
hereof.

                                     FORM OF
          RESOLUTIONS ESTABLISHING DESIGNATIONS, PREFERENCES AND RIGHTS

                                       of

                  Series A Junior Participating Preferred Stock

                                       of

                                KIRBY CORPORATION

     Pursuant to Sections 78.195 and 78.1955 of the Nevada Revised Statutes

                  RESOLVED,  that pursuant to the authority  vested in the Board
         of Directors of this  Corporation in accordance  with the provisions of
         the Restated  Articles of  Incorporation,  a series of Preferred Stock,
         par value $1.00 per share, of the Corporation be and hereby is created,
         and that the  designation  and number of shares  thereof and the voting
         and other powers, preferences and relative, participating,  optional or
         other  rights of the  shares  of such  series  and the  qualifications,
         limitations and restrictions thereof are as follows:

                      Series A Junior Participating Preferred Stock

                  1.  Designation  and  Amount.  There  shall  be  a  series  of
Preferred  Stock that  shall be  designated  as  "Series A Junior  Participating
Preferred  Stock," and the number of shares  constituting  such series  shall be
1,000,000.  Such number of shares may be increased or decreased by resolution of
the Board of Directors;  provided,  however,  that no decrease  shall reduce the
number of shares of Series A Junior  Participating  Preferred Stock to less than
the  number of shares  then  issued  and  outstanding  plus the number of shares
issuable  upon  exercise  of  outstanding  rights,  options or  warrants or upon
conversion of outstanding securities issued by the Corporation.

                  2.  Dividends and Distributions.

                  (A) Subject to the prior and superior rights of the holders of
any shares of any series of Preferred  Stock  ranking  prior and superior to the
shares  of  Series  A Junior  Participating  Preferred  Stock  with  respect  to
dividends,  the  holders  of shares of Series A Junior  Participating  Preferred
Stock, in preference to the holders of shares of any class or series of stock of
the Corporation  ranking junior to the Series A Junior  Participating  Preferred
Stock,  shall be entitled to receive,  when,  as and if declared by the Board of
Directors out of funds legally  available for the purpose,  quarterly  dividends
payable in cash on the 15th day of  February,  May,  August and November in each
year (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

                                      A-1

<PAGE>



or fraction of a share of Series A Junior  Participating  Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00
or (b) the  Adjustment  Number (as defined  below) times the aggregate per share
amount of all cash dividends,  and the Adjustment Number times the aggregate per
share amount (payable in kind) of all non-cash dividends or other  distributions
other than a dividend  payable in shares of Common Stock or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise),  declared
on the Common Stock,  par value $.10 per share, of the Corporation  (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 A Junior  Participating
Preferred  Stock.  The "Adjustment  Number" shall initially be 100. In the event
the Corporation  shall at any time after July 18, 2000 (the "Rights  Declaration
Date") (i) declare  any  dividend  on Common  Stock  payable in shares of Common
Stock,  (ii)  subdivide  the  outstanding  Common  Stock  or (iii)  combine  the
outstanding Common Stock into a smaller number of shares, 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.

                  (B) The  Corporation  shall declare a dividend or distribution
on the Series A Junior  Participating  Preferred  Stock as provided in paragraph
(A) above 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 A Junior  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 A Junior  Participating  Preferred  Stock from the
Quarterly  Dividend Payment Date next preceding the date of issue of such shares
of Series A Junior  Participating  Preferred Stock,  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 A Junior 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  A  Junior  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 fix a record date for the  determination  of holders of shares of
Series A Junior  Participating  Preferred Stock entitled to receive payment of a
dividend or distribution  declared  thereon,  which record date shall be no more
than 30 days prior to the date fixed for the payment thereof.

                  3.  Voting Rights. The  holders of shares  of Series A  Junior
Participating Preferred Stock shall have the following voting rights:

                                      A-2

<PAGE>



                  (A) Each  share of  Series  A Junior  Participating  Preferred
Stock  shall  entitle  the  holder  thereof  to a number  of votes  equal to the
Adjustment  Number on all matters submitted to a vote of the stockholders of the
Corporation.

                  (B)  Except as  otherwise  provided  herein,  in the  Restated
Articles of  Incorporation  or by law,  the holders of shares of Series A Junior
Participating  Preferred  Stock,  the  holders  of shares of any other  class or
series  entitled  to vote with the  Common  Stock and the  holders  of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

                  (C)(i)  If at any  time  dividends  on  any  Series  A  Junior
Participating  Preferred  Stock  shall be in arrears  in an amount  equal to six
quarterly  dividends thereon,  the occurrence of such contingency shall mark the
beginning of a period (herein called a "default period") that shall extend until
such time when all  accrued  and unpaid  dividends  for all  previous  quarterly
dividend periods and for the current quarterly  dividend period on all shares of
Series A Junior  Participating  Preferred Stock then outstanding shall have been
declared and paid or set apart for payment.  During each default period, (1) the
number of  Directors  shall be  increased  by two,  effective  as of the time of
election of such Directors as herein provided,  and (2) the holders of Preferred
Stock (including holders of the Series A Junior  Participating  Preferred Stock)
upon which these or like voting rights have been  conferred and are  exercisable
(the "Voting  Preferred  Stock") with dividends in arrears in an amount equal to
six quarterly  dividends  thereon,  voting as a class,  irrespective  of series,
shall have the right to elect such two Directors.

                  (ii)  During any  default  period,  such  voting  right of the
holders  of  Series A Junior  Participating  Preferred  Stock  may be  exercised
initially at a special  meeting called  pursuant to  subparagraph  (iii) of this
Section 3(C) or at any annual meeting of stockholders,  and thereafter at annual
meetings of stockholders, provided that such voting right shall not be exercised
unless  the  holders  of at least  one-third  in number of the  shares of Voting
Preferred Stock  outstanding shall be present in person or by proxy. The absence
of a quorum of the holders of Common  Stock shall not affect the exercise by the
holders of Voting Preferred Stock of such voting right.

                  (iii)  Unless the  holders of Voting  Preferred  Stock  shall,
during an existing  default  period,  have  previously  exercised their right to
elect  Directors,  the Board of  Directors  may  order,  or any  stockholder  or
stockholders  owning in the  aggregate  not less than ten  percent  of the total
number of shares of Voting Preferred Stock outstanding,  irrespective of series,
may request, the calling of a special meeting of the holders of Voting Preferred
Stock, which meeting shall thereupon be called by the Chairman of the Board, the
President, a Vice President or the Secretary of the Corporation.  Notice of such
meeting and of any annual meeting at which holders of Voting Preferred Stock are
entitled to vote  pursuant  to this  paragraph  (C)(iii)  shall be given to each
holder of record of Voting  Preferred  Stock by mailing a copy of such notice to
him at his last  address as the same  appears  on the books of the  Corporation.
Such  meeting  shall be called for a time not earlier than 20 days and not later
than 60 days after such order or request  or, in default of the  calling of such
meeting  within 60 days after such order or request,  such meeting may be called
on similar notice by any stockholder or stockholders owning in the aggregate not
less than ten percent of the total  number of shares of Voting  Preferred  Stock
outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such

                                      A-3

<PAGE>



special  meeting shall be called  during the period  within 60 days  immediately
preceding the date fixed for the next annual meeting of the stockholders.

                  (iv) In any  default  period,  after  the  holders  of  Voting
Preferred Stock shall have exercised their right to elect Directors  voting as a
class,  (x) the  Directors so elected by the holders of Voting  Preferred  Stock
shall continue in office until their  successors shall have been elected by such
holders or until the  expiration of the default  period,  and (y) any vacancy in
the Board of  Directors  may be filled by vote of a  majority  of the  remaining
Directors  theretofore  elected by the  holders of the class or classes of stock
which elected the Director whose office shall have become vacant.  References in
this paragraph (C) to Directors  elected by the holders of a particular class or
classes of stock  shall  include  Directors  elected by such  Directors  to fill
vacancies as provided in clause (y) of the foregoing sentence.

                  (v) Immediately  upon the expiration of a default period,  (x)
the right of the holders of Voting Preferred Stock as a class to elect Directors
shall  cease,  (y) the term of any  Directors  elected by the  holders of Voting
Preferred Stock as a class shall terminate and (z) the number of Directors shall
be such number as may be provided for in the Restated  Articles of Incorporation
or By-Laws  irrespective  of any increase  made  pursuant to the  provisions  of
paragraph (C) of this Section 3 (such number being subject,  however,  to change
thereafter  in  any  manner  provided  by law or in  the  Restated  Articles  of
Incorporation or By-Laws).  Any vacancies in the Board of Directors  effected by
the provisions of clauses (y) and (z) in the preceding sentence may be filled by
a majority of the remaining Directors.

                  (D)  Except as set forth  herein,  holders  of Series A Junior
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.

                  4.       Certain Restrictions.

                  (A)  Whenever  quarterly   dividends  or  other  dividends  or
distributions  payable on the Series A Junior  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
A Junior Participating Preferred Stock outstanding shall have been paid in full,
the Corporation 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
         A Junior Participating Preferred Stock;

                                      A-4

<PAGE>




                           (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 A Junior  Participating  Preferred Stock,  except dividends paid
         ratably on the Series A Junior  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; or

                           (iii)  redeem or  purchase or  otherwise  acquire for
         consideration  any  shares of Series A Junior  Participating  Preferred
         Stock,  or any shares of stock  ranking  on a parity  with the Series A
         Junior  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 Series A Junior  Participating
         Preferred  Stock,  or to all such  holders  and the holders of any such
         shares ranking on a parity  therewith,  upon such terms as the Board of
         Directors,  after consideration of the respective annual dividend rates
         and other relative rights and preferences of the respective  series and
         classes,  shall  determine  in good  faith  will  result  in  fair  and
         equitable treatment among the respective series or classes.

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

                  5.   Reacquired   Shares.   Any  shares  of  Series  A  Junior
Participating Preferred Stock purchased or otherwise acquired by the Corporation
in any  manner  whatsoever  shall be retired  and  canceled  promptly  after the
acquisition  thereof.  All such  shares  shall  upon their  cancellation  become
authorized but unissued shares of Preferred Stock and may be reissued as part of
a new series of Preferred  Stock to be created by resolution or  resolutions  of
the Board of Directors,  subject to any conditions and  restrictions on issuance
set forth herein.

                  6.  Liquidation,  Dissolution  or  Winding  Up.  (A)  Upon any
liquidation  (voluntary  or  otherwise),   dissolution  or  winding  up  of  the
Corporation,  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 A Junior  Participating  Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating  Preferred Stock
shall have received  $100 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 A Junior  Participating  Preferred  Stock  Liquidation
Preference").  Following  the  payment of the full amount of the Series A Junior
Participating   Preferred   Stock   Liquidation   Preference,    no   additional
distributions  shall  be made to the  holders  of  shares  of  Series  A  Junior
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 A Junior Participating
Preferred Stock Liquidation Preference by (ii) the Adjustment Number.  Following
the  payment of the full amount of the Series A Junior  Participating  Preferred
Stock  Liquidation  Preference  and the  Common  Adjustment  in  respect  of all
outstanding shares of Series A Junior  Participating  Preferred Stock and Common
Stock,  respectively,  holders of Series A Junior Participating  Preferred Stock
and holders of shares of Common Stock

                                      A-5

<PAGE>



shall,  subject to the prior rights of all other series of Preferred  Stock,  if
any, ranking prior thereto, 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 A Junior  Participating  Preferred  Stock and Common
Stock, on a per share basis, respectively.

                  (B) In the  event,  however,  that  there  are not  sufficient
assets available to permit payment in full of the Series A Junior  Participating
Preferred Stock  Liquidation  Preference and the liquidation  preferences of all
other series of Preferred Stock, if any, that rank on a parity with the Series A
Junior  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, however, that 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) Neither  the merger or  consolidation  of the  Corporation
into or with another  corporation nor the merger or  consolidation  of any other
corporation  into or with the  Corporation  shall be deemed to be a liquidation,
dissolution or winding up of the Corporation  within the meaning of this Section
6,  but  the  sale,  lease  or  conveyance  of  all  or  substantially  all  the
Corporation's assets shall be deemed to be a liquidation, dissolution or winding
up of the Corporation within the meaning of this Section 6.

                  7.  Consolidation,  Merger, etc. In case the Corporation shall
enter into any  consolidation,  merger,  combination,  share  exchange  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 each share of Series A Junior  Participating  Preferred  Stock shall at the
same time be similarly  exchanged or changed in an amount per share equal to the
Adjustment Number 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.

                  8. Redemption. (A) The Corporation,  at its option, may redeem
shares of the Series A Junior Participating Preferred Stock in whole at any time
and in part from time to time,  at a  redemption  price equal to the  Adjustment
Number  times the current per share  market  price (as such term is  hereinafter
defined)  of the  Common  Stock  on the date of the  mailing  of the  notice  of
redemption,  together  with  unpaid  accumulated  dividends  to the date of such
redemption.  The "current per share market price" on any date shall be deemed to
be the average of the closing  price per share of such Common  Stock for the ten
consecutive Trading Days (as such term is hereinafter defined) immediately prior
to such date;  provided,  however,  that in the event that the current per share
market price of the Common Stock is  determined  during a period  following  the
announcement  of (A) a dividend or distribution on the Common Stock other than a
regular  quarterly  cash  dividend  or  (B)  any  subdivision,   combination  or
reclassification of such Common Stock and the ex-dividend date for such dividend
or  distribution,  or the  record  date for  such  subdivision,  combination  or
reclassification,  shall not have occurred prior to the commencement of such ten
Trading Day period,  then,  and in each such case,  the current per share market
price shall be properly adjusted to take into account ex-dividend  trading.  The
closing  price for each day shall be the last sales  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
transaction reporting system with respect to securities listed or

                                      A-6

<PAGE>



admitted to trading on the New York Stock  Exchange,  or, if the Common Stock is
not  listed or  admitted  to  trading  on the New York  Stock  Exchange,  on the
principal  national  securities  exchange on which the Common Stock is listed or
admitted  to  trading,  or, if the  Common  Stock is not listed or  admitted  to
trading on any  national  securities  exchange  but sales price  information  is
reported  for  such  security,  as  reported  by  the  National  Association  of
Securities  Dealers,  Inc. Automated  Quotations System ("NASDAQ") or such other
self-regulatory  organization or registered securities information processor (as
such terms are used under the Securities  Exchange Act of 1934, as amended) that
then  reports  information  concerning  the  Common  Stock,  or, if sales  price
information is not so reported, the average of the high bid and low asked prices
in the over-the-counter  market on such day, as reported by NASDAQ or such other
entity,  or,  if on any such  date the  Common  Stock is not  quoted by any such
entity,  the  average of the  closing  bid and asked  prices as  furnished  by a
professional  market maker  making a market in the Common Stock  selected by the
Board of Directors of the Corporation.  If on any such date no such market maker
is making a market in the Common  Stock,  the fair value of the Common  Stock on
such  date  as  determined  in good  faith  by the  Board  of  Directors  of the
Corporation  shall be used. The term "Trading Day" shall mean a day on which the
principal  national  securities  exchange on which the Common Stock is listed or
admitted to trading is open for the  transaction of business,  or, if the Common
Stock is not listed or admitted to trading on any national  securities  exchange
but is quoted by NASDAQ, a day on which NASDAQ reports trades, or, if the Common
Stock is not so quoted,  a Monday,  Tuesday,  Wednesday,  Thursday  or Friday on
which  banking  institutions  in  the  Commonwealth  of  Massachusetts  are  not
authorized or obligated by law or executive order to close.

                  (B) In the event that fewer than all the outstanding shares of
the Series A Junior Participating Preferred Stock are to be redeemed, the number
of shares to be redeemed  shall be  determined by the Board of Directors and the
shares  to be  redeemed  shall  be  determined  by  lot or  pro  rata  as may be
determined  by the  Board  of  Directors  or by any  other  method  that  may be
determined by the Board of Directors in its sole discretion to be equitable.

                  (C) Notice of any such redemption shall be given by mailing to
the holders of the shares of Series A Junior Participating Preferred Stock to be
redeemed a notice of such  redemption,  first class postage  prepaid,  not later
than the  fifteenth  day and not earlier  than the  sixtieth day before the date
fixed for  redemption,  at their last  address as the same shall appear upon the
books of the Corporation. Each such notice shall state: (i) the redemption date;
(ii) the number of shares to be redeemed  and, if fewer than all the shares held
by such holder are to be redeemed, the number of such shares to be redeemed from
such  holder;  (iii)  the  redemption  price;  (iv) the  place or  places  where
certificates for such shares are to be surrendered for payment of the redemption
price;  and (v) that dividends on the shares to be redeemed will cease to accrue
on the close of business on such  redemption  date. Any notice that is mailed in
the manner  herein  provided  shall be  conclusively  presumed to have been duly
given,  whether or not the stockholder received such notice, and failure duly to
give such notice by mail, or any defect in such notice,  to any holder of Series
A Junior  Participating  Preferred  Stock  shall not affect the  validity of the
proceedings  for  the  redemption  of  any  other  shares  of  Series  A  Junior
Participating  Preferred  Stock  that are to be  redeemed.  On or after the date
fixed for redemption as stated in such notice,  each holder of the shares called
for redemption  shall  surrender the  certificate  evidencing such shares to the
Corporation  at the place  designated  in such  notice  and shall  thereupon  be
entitled to receive payment of the redemption price. If fewer than

                                      A-7

<PAGE>



all the shares represented by any such surrendered  certificate are redeemed,  a
new certificate shall be issued representing the unredeemed shares.

                  (D) The  shares  of  Series A Junior  Participating  Preferred
Stock  shall not be subject to the  operation  of any  purchase,  retirement  or
sinking fund.

                  9. Ranking. The Series A Junior Participating  Preferred Stock
shall rank junior to all other series of the Corporation's Preferred Stock as to
the payment of dividends and the distribution of assets, unless the terms of any
such series shall provide  otherwise,  and shall rank senior to the Common Stock
as to such matters.

                  10. Amendment.  At any time that any shares of Series A Junior
Participating  Preferred  Stock  are  outstanding,   the  Restated  Articles  of
Incorporation of the Corporation  shall not be amended in any manner which would
materially  alter or change the  powers,  preferences  or special  rights of the
Series A Junior  Participating  Preferred  Stock so as to affect them  adversely
without  the  affirmative  vote  of the  holders  of  two-thirds  or more of the
outstanding  shares of Series A Junior  Participating  Preferred  Stock,  voting
separately as a class.

                  11. Fractional Shares. Series A Junior Participating Preferred
Stock may be issued in  fractions of a share that 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 A Junior Participating Preferred Stock.

                  IN  WITNESS   WHEREOF,   the  undersigned  has  executed  this
Certificate and does affirm the foregoing as true this ___ day of _______, 200_.

                                KIRBY CORPORATION

                  This  certifies  that  _____________________,   or  registered
assigns,  is the registered owner of the number of Rights set forth above,  each
of which  entitles  the owner  thereof,  subject  to the terms,  provisions  and
conditions  of the Rights  Agreement,  dated as of July 18,  2000 as it may from
time to time be supplemented or amended (the "Rights Agreement"),  between Kirby

national banking  association (the "Rights Agent"), to purchase from the Company
at any time prior to 5:00 p.m.  (Eastern time) on July 18, 2010 at the principal

successors as Rights Agent,  one  one-hundredth  of a fully paid,  nonassessable
share (a "Fractional Share") of Series A Junior  Participating  Preferred Stock,

                  From and after the first  occurrence of a Triggering Event (as
such term is defined in the Rights  Agreement),  if the Rights evidenced by this
Rights  Certificate are beneficially owned by or transferred to (i) an Acquiring
Person or an Associate  or  Affiliate of an Acquiring  Person (as such terms are
defined  in the  Rights  Agreement),  (ii) a  transferee  of any such  Acquiring
Person,  Associate or Affiliate,  or (iii) under certain circumstances specified
in the Rights  Agreement,  a transferee  of a person who,  concurrently  with or
after such transfer,  became an Acquiring Person or an Affiliate or Associate of
an Acquiring Person, such Rights shall, with certain exceptions, become null and
void in the  circumstances  set  forth in the  Rights  Agreement,  and no holder
hereof  shall have any rights  whatsoever  with  respect to such Rights from and
after the occurrence of such Triggering Event.

                  As provided in the Rights  Agreement,  the Purchase  Price and
the number and kind of shares of Preferred  Stock or other  securities or assets
that may be purchased  upon the exercise of the Rights  evidenced by this Rights
Certificate  are subject to  modification  and adjustment  upon the happening of
certain events, including Triggering Events.

                  This  Rights  Certificate  is  subject  to all  of the  terms,
provisions and conditions of the Rights Agreement,  which terms,  provisions and
conditions  are hereby  incorporated  herein by reference and made a part hereof
and to which Rights Agreement reference is hereby made for a full description of
the rights, limitations of rights, obligations,  duties and immunities hereunder
of the Rights  Agent,  the Company  and the holders of the Rights  Certificates,
which   limitations   of  rights   include  the  temporary   suspension  of  the
exercisability of such Rights under the specific  circumstances set forth in the
Rights   Agreement.   Copies  of  the  Rights  Agreement  are  on  file  at  the
above-mentioned  office of the Rights Agent and are also  available upon written
request to the Company or the Rights Agent.

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

                  Subject to the provisions of the Rights Agreement,  the Rights
evidenced by this  Certificate  (i) may be redeemed by the Company at its option
at a  redemption  price of $0.01 per  Right,  payable,  at the  election  of the
Company,  in cash or shares of Common Stock or such other  consideration  as the
Board of Directors may determine,  at any time prior to the earlier of the close
of business on (a) the tenth day following the first public  announcement of the
occurrence  of a Flip-In Event (as such time period may be extended or shortened
pursuant to the Rights  Agreement) and (b) the Expiration  Date (as such term is
defined in the Rights  Agreement)  or (ii) may be  exchanged in whole or in part
for shares of Common Stock and/or other equity  securities of the Company deemed
to have the  same  value as  shares  of  Common  Stock,  at any time  prior to a
person's  becoming the  beneficial  owner of 50% or more of the shares of Common
Stock  outstanding  or  the  occurrence  of a  Flip-Over  Event.  Under  certain
circumstances set forth in the Rights Agreement, the decision to

Directors (as defined in the Rights Agreement).

                  No  fractional  shares of  Preferred  Stock are required to be
issued upon the exercise of any Right or Rights  evidenced  hereby  (other than,
except as set forth above, fractions that are integral multiples of a Fractional
Share of  Preferred  Stock,  which  may,  at the  election  of the  Company,  be
evidenced  by  depositary  receipts),  but in lieu thereof a cash payment may be
made, as provided in the Rights Agreement.

                  No  holder  of this  Rights  Certificate,  as  such,  shall be
entitled to vote or receive dividends or be deemed for any purpose the holder of
shares of Preferred Stock or of any other  securities of the Company that may at
any time be issuable on the exercise hereof, nor shall anything contained in the
Rights  Agreement or herein be construed  to confer upon the holder  hereof,  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 the Rights  Agreement),  or to receive  dividends  or  subscription
rights,  or  otherwise,  until  the  Right or Rights  evidenced  by this  Rights
Certificate shall have been exercised as provided in the Rights Agreement.

                  This Rights  Certificate  shall not be valid or obligatory for
any purpose until it shall have been countersigned by the Rights Agent.

Under  certain   circumstances  set  forth  in  the  Rights  Agreement,   Rights
beneficially  owned by or  transferred  to any  Person who is, was or becomes an
Acquiring Person or an Affiliate or Associate thereof (as such terms are defined
in the Rights Agreement),  and certain transferees thereof, will become null and
void and will no longer be transferable.

                                SUMMARY OF RIGHTS

                  On July 18, 2000, the Board of Directors of Kirby  Corporation
(the "Company")  declared a dividend of one right ("Right") for each outstanding
share of the Company's Common Stock, par value $.10 per share ("Common  Stock"),
to  stockholders  of record at the close of  business on August 15,  2000.  Each
Right  entitles  the  registered  holder  to  purchase  from the  Company a unit
consisting of one  one-hundredth  of a share (a "Fractional  Share") of Series A
Junior Participating  Preferred Stock, par value $1.00 per share (the "Preferred
Stock"), at a purchase price of $92 per Fractional Share,  subject to adjustment
(the "Purchase Price"). The description and terms of the Rights are set forth in
a Rights  Agreement  dated as of July  18,  2000 as it may from  time to time be
supplemented or amended (the "Rights  Agreement")  between the Company and Fleet
National Bank, as Rights Agent.

                  Initially,  the Rights will be evidenced  by the  certificates
representing  outstanding  shares of Common Stock, and no separate  certificates
for the Rights  ("Rights  Certificates")  will be  distributed.  The Rights will
separate  from the  Common  Stock and a  "Distribution  Date" will  occur,  with
certain  exceptions,  upon  the  earlier  of (i) ten  days  following  a  public
announcement  that a person or group of  affiliated  or  associated  persons (an
"Acquiring Person") has acquired,  or obtained the right to acquire,  beneficial
ownership of 15% or more of the outstanding  shares of Common Stock (the date of
the announcement being the "Stock Acquisition  Date"), or (ii) ten business days
following the commencement of a tender offer or exchange offer that would result
in a person's becoming an Acquiring Person.  Charles Berdon Lawrence and related
trusts,  which  beneficially  owned  approximately 18% of the outstanding Common
Stock at the time the Rights  Agreement was adopted,  and their  affiliates  and
associates,  will not become Acquiring Persons unless certain increases in their
aggregate  beneficial  ownership  occur or are  deemed  to occur  such that such
aggregate  beneficial  ownership exceeds 23% of the outstanding shares of Common
Stock. In certain  circumstances,  the Distribution  Date may be deferred by the
Board of  Directors.  Certain  inadvertent  acquisitions  will not  result  in a
person's  becoming an Acquiring  Person if the person promptly divests itself of
sufficient  Common Stock.  Until the  Distribution  Date, (a) the Rights will be
evidenced by the Common Stock certificates (together with a copy of this Summary
of Rights or bearing the  notation  referred  to below) and will be  transferred
with  and only  with  such  Common  Stock  certificates,  (b) new  Common  Stock
certificates  issued after July 18, 2000 will  contain a notation  incorporating
the Rights  Agreement by  reference  and (c) the  surrender  for transfer of any
certificate  for Common Stock (with or without a copy of this Summary of Rights)
will also constitute the transfer of the Rights associated with the Common Stock
represented by such certificate.

                  The Rights are not exercisable until the Distribution Date and
will expire at the close of business on July 18, 2010,  unless earlier  redeemed
or exchanged by the Company as described below.

                  As soon as practicable  after the  Distribution  Date,  Rights
Certificates will be mailed to holders of record of Common Stock as of the close
of business on the Distribution Date and, from and after the Distribution  Date,
the separate Rights  Certificates alone will represent the Rights. All shares of
Common Stock issued prior to the  Distribution  Date will be issued with Rights.
Shares of Common Stock issued after the  Distribution  Date in  connection  with
certain employee benefit plans or upon conversion of certain  securities will be
issued with Rights. Except as otherwise determined by the Board of Directors, no
other shares of Common Stock issued after the  Distribution  Date will be issued
with Rights.

                  In the event (a  "Flip-In  Event")  that a person  becomes  an
Acquiring  Person  except  pursuant  to a  tender  or  exchange  offer  for  all
outstanding  shares of Common  Stock at a price and on terms that a majority  of
the independent  Continuing  Directors (as hereinafter defined) determines to be
fair to and otherwise in the best interests of the Company and its  stockholders
(a "Permitted Offer")), each holder of a Right will thereafter have the right to
receive, upon exercise of such Right, a number of shares of Common Stock (or, in
certain circumstances, cash, property or other securities of the Company) having
a Current Market Price (as defined in the Rights  Agreement)  equal to two times
the exercise price of the Right.  Notwithstanding  the foregoing,  following the
occurrence  of any  Triggering  Event,  all Rights that are,  or (under  certain
circumstances  specified in the Rights Agreement) were, beneficially owned by or
transferred to an Acquiring  Person (or by certain related parties) will be null
and void in the circumstances set forth in the Rights Agreement. However, Rights
are not  exercisable  following  the  occurrence of any Flip-In Event until such
time as the Rights are no longer redeemable by the Company as set forth below.

                  For example, at an exercise price of $92 per Right, each Right
not owned by an Acquiring  Person (or by certain related  parties)  following an
event set forth in the preceding  paragraph would entitle its holder to purchase
$184 worth of Common Stock (or other consideration,  as noted above), based upon
its then Current  Market  Price,  for $92.  Assuming that the Common Stock had a
Current  Market  Price of $23 per share at such  time,  the holder of each valid
Right would be entitled to purchase 8 shares of Common Stock for $92.

                  In the event (a "Flip-Over  Event") that, at any time from and
after the time an Acquiring  Person becomes such, (i) the Company is acquired in
a merger or other business  combination  transaction (other than certain mergers
that follow a Permitted  Offer),  or (ii) 50% or more of the Company's assets or
earning power is sold or transferred, each holder of a Right (except Rights that
are voided as set forth above) shall thereafter have the right to receive,  upon
exercise,  a number of shares of common stock of the acquiring  company having a
Current Market Price equal to two times the exercise price of the Right. Flip-In
Events and Flip-Over Events are collectively referred to as "Triggering Events."

                  The number of outstanding  Rights  associated  with a share of
Common Stock,  or the number of Fractional  Shares of Preferred  Stock  issuable
upon  exercise of a Right and the Purchase  Price,  are subject to adjustment in
the  event  of  a  stock   dividend  on,  or  a   subdivision,   combination  or
reclassification  of, the Common Stock occurring prior to the Distribution Date.
The Purchase  Price  payable,  and the number of Fractional  Shares of Preferred
Stock or other securities or property

                                       C-2


<PAGE>



issuable,  upon  exercise of the Rights are subject to  adjustment  from time to
time to prevent  dilution  in the event of certain  transactions  affecting  the
Preferred Stock.

                  With certain  exceptions,  no adjustment in the Purchase Price
will be  required  until  cumulative  adjustments  amount  to at least 1% of the
Purchase  Price.  No fractional  shares of Preferred Stock that are not integral
multiples  of a  Fractional  Share are  required to be issued  upon  exercise of
Rights  and, in lieu  thereof,  an  adjustment  in cash may be made based on the
market price of the  Preferred  Stock on the last trading date prior to the date
of exercise. Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the occurrence of a Triggering Event that, upon any exercise of
Rights,  a number of Rights be  exercised so that only whole shares of Preferred
Stock will be issued.

                  At any time until ten days  following the first date of public
announcement  of the occurrence of a Flip-In  Event,  the Company may redeem the
Rights in whole, but not in part, at a price of $0.01 per Right, payable, at the
option  of  the  Company,  in  cash,  shares  of  Common  Stock  or  such  other
consideration   as  the  Board  of  Directors  may   determine.   Under  certain
circumstances  set forth in the Rights  Agreement,  the decision to redeem shall
require the concurrence of a majority of the Continuing  Directors.  Immediately
upon  the  effectiveness  of the  action  of the  Board  of  Directors  ordering
redemption  of  the  Rights,  with,  where  required,  the  concurrence  of  the
Continuing  Directors,  the  Rights  will  terminate  and the only  right of the
holders of Rights will be to receive the $0.01 redemption price.

                  The term  "Continuing  Director" means any member of the Board
of  Directors  of the  Company,  while  such  Person is a member of the Board of
Directors  of the  Company,  who is not an officer or employee of the Company or
any  Subsidiary  of the  Company  and  who is not  an  Acquiring  Person,  or an
Affiliate or Associate of an Acquiring Person, or a nominee or representative of
an Acquiring  Person or of any such  Affiliate or Associate,  if (i) such Person
was a member of the Board of Directors of the Company prior to the time a Person
becomes an Acquiring  Person or (ii) such  Person's  nomination  for election or
election to the Board of Directors of the Company is  recommended or approved by
a majority of the then Continuing Directors.

                  At any time after the  occurrence of a Flip-In Event and prior
to a  person's  becoming  the  beneficial  owner of 50% or more of the shares of
Common  Stock then  outstanding  or the  occurrence  of a Flip-Over  Event,  the
Company (with the  concurrence  of a majority of the  Continuing  Directors) may
exchange  the Rights  (other  than  Rights  owned by an  Acquiring  Person or an
affiliate or an associate of an Acquiring Person,  which will have become void),
in whole or in part, at an exchange  ratio of one share of Common Stock,  and/or
other  equity  securities  deemed to have the same  value as one share of Common
Stock, per Right, subject to adjustment.

                  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.  While the distribution of the Rights
should not be taxable  to  stockholders  or to the  Company,  stockholders  may,
depending upon the circumstances, recognize taxable income in the event that the
Rights  become  exercisable  for Common  Stock (or other  consideration)  of the
Company or for the

                                       C-3

common  stock of the  acquiring  company as set forth above or are  exchanged as
provided in the preceding paragraph.

                  Other than the redemption  price, any of the provisions of the
Rights  Agreement  may be amended by the Board of  Directors  of the Company (in
certain circumstances, with the concurrence of the Continuing Directors) as long
as the Rights are redeemable. Thereafter, the provisions of the Rights Agreement
other than the  redemption  price may be amended by the Board of  Directors  (in
certain  circumstances,  with the  concurrence of the  Continuing  Directors) in
order to cure any ambiguity,  defect or  inconsistency,  to make changes that do
not materially  adversely  affect the interests of holders of Rights  (excluding
the  interests  of any  Acquiring  Person),  or to shorten or lengthen  any time
period  under the Rights  Agreement;  provided,  however,  that no  amendment to
lengthen the time period governing  redemption shall be made at such time as the
Rights are not redeemable.

                  A copy  of the  Rights  Agreement  has  been  filed  with  the
Securities  and Exchange  Commission  as an exhibit to a Current  Report on Form
8-K. A copy of the Rights Agreement is available free of charge from the Company
and the Rights Agent. This summary description of the Rights does not purport to
be  complete  and is  qualified  in its  entirety  by  reference  to the  Rights
Agreement, which is incorporated herein by reference.
