Common Stock Purchase Rights

Item 1.  Description of Registrant's Securities to be Registered

                  On February 20, 1998, the Board of Directors of SPSS Inc. (the
"Company")  declared a dividend of one common share  purchase  right (a "Right")
for each  outstanding  share of  common  stock,  par value  $.01 per share  (the
"Common Shares"), of the Company. The dividend was payable on June 30, 1998 (the
"Record Date") to the  stockholders  of record on that date. Upon the occurrence
of certain  events,  each Right entitles the registered  holder to purchase from
the Company one common  share of the Company at a price of $175 per Common Share
(the "Purchase Price"), subject to adjustment.  The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights  Agreement") between the
Company and Harris Trust and Savings Bank, as Rights Agent (the "Rights Agents).

                  Initially,   with   respect  to  any  of  the   Common   Share
certificates  outstanding as of the Record Date, the Rights will be evidenced by
a Common  Share  certificate  together  with a copy of this  Summary  of  Rights
attached thereto and no separate Rights  Certificates will be distributed.  With
respect to Common Share  certificates  issued after the Record Date,  the Rights
will be evidenced by a legend affixed to each such certificate incorporating the
Rights Agreement by reference.

                  The Rights  are not  exercisable  and are not freely  tradable
separate from the Common  Shares until the  occurrence  of a  Distribution  Date
("Distribution  Date").  A  Distribution  Date occurs upon the earlier of (i) 10
days  following a public  announcement  that a person or group of  affiliated or
associated  persons  have  acquired  beneficial  ownership of 15% or more of the
outstanding Common Shares ("Acquiring Person") or (ii) 10 business days (or some
later date as the Board of Directors may determine)  following the  commencement
of, or announcement of an intention to make, a tender offer or exchange offer by
a person or group of affiliated or associated persons, the consummation of which
would  result  in the  beneficial  ownership  of 15% or more of the  outstanding
Common Shares or where Continuing Directors deem certain events have constituted
an Adverse Change of Control (as herein more fully described).

                  The Rights  Agreement  provides that,  until the  Distribution
Date (or an earlier  redemption or  expiration  of the Rights),  the Rights will
only be transferred with the Common Shares,  however, the surrender for transfer
of any  certificates  for Common Shares  outstanding as of the Record Date, even
without a legend or a copy of this  Summary of Rights  being  attached  thereto,
will also  constitute  the  transfer  of the Rights  associated  with the Common
Shares  represented  by such  certificate.  As soon as  practicable  following a
Distribution  Date,   separate   certificates   evidencing  the  Rights  ("Right
Certificates")  will be mailed to holders  of record of the Common  Shares as of
the  close  of  business  on the  Distribution  Date  and  such  separate  Right
Certificates alone will evidence the Rights. Such Rights are, however,  null and
void as to any Acquiring Person.


                                      - 2 -

<PAGE>



                  The Rights will expire on June 18, 2008 (the "Final Expiration
Date"),  unless the Final  Expiration  Date is extended or unless the Rights are
earlier redeemed or exchanged by the Company, in each case, as described below.

                  The Purchase Price payable, and the number of Common Shares or
other securities or property issuable,  upon exercise of the Rights, are subject
to customary  adjustments from time to time to prevent dilution (i) in the event
of a stock dividend on, or a subdivision,  combination or  reclassification  of,
the  Common  Shares,  (ii) upon the grant to  holders  of the  Common  Shares of
certain  rights or warrants to  subscribe  for or  purchase  Common  Shares at a
price,  or securities  convertible  into Common Shares with a conversion  price,
less than the  then-current  market price of the Common Shares or (iii) upon the
distribution  to holders of the Common  Shares of evidences of  indebtedness  or
assets  (excluding  regular  periodic  cash  dividends  paid out of  earnings or
retained  earnings or  dividends  payable in Common  Shares) or of  subscription
rights or warrants (other than those referred to above).

                  With certain  exceptions,  no adjustment in the Purchase Price
will be required until cumulative  adjustments amount to an increase or decrease
of at least 1% in such  Purchase  Price.  The  Company  shall not be required to
issue  fractional  Rights or shares and in lieu  thereof,  an adjustment in cash
will be made based on the current market value of the Rights or shares.

                  In the  event  that  any  person  or group  of  affiliated  or
associated  persons becomes an Acquiring Person,  proper provision shall be made
so that each  holder of a Right,  other than  Rights  beneficially  owned by the
Acquiring  Person (which are void),  will  thereafter have the right to receive,
upon  exercise of the Right,  that number of Common Shares having a market value
of two times the exercise price of the Right.

                  In the event that the Company is acquired in a merger or other
business  combination  transaction or 50% or more of its consolidated  assets or
earning  power are sold after a person or group has become an Acquiring  Person,
each  holder of a Right  will  thereafter  have the right to  receive,  upon the
exercise thereof at the then current exercise price of the Right, that number of
shares  of  common  stock  of the  acquiring  company  which at the time of such
transaction  will have a market  value of two times  the  exercise  price of the
Right, or in circumstances such as where the Right cannot be exercised for stock
or the assets of the Company have been  distributed,  an amount of cash equal to
the value of such Rights shall be paid.

                  At any time  after any person or group  becomes  an  Acquiring
Person and prior to the  acquisition  by such  person or group of 50% or more of
the  outstanding  Common  Shares,  the Board of  Directors  of the  Company  may
exchange the Rights  (other than Rights owned by such person or group which will
have  become  void),  in whole or in part,  at an  exchange  ratio of one Common
Share, per Right (subject to adjustment).

<PAGE>



                  At any time prior to the  acquisition  by a person or group of
affiliated or associated  persons of beneficial  ownership of 15% or more of the
outstanding  Common Shares, the Board of Directors of the Company may redeem the
Rights in whole,  but not in part, at a price of $.01 per Right (the "Redemption
Price") provided,  however,  if the authorization to redeem the Rights occurs on
or after the date of a change in a  majority  of the Board of  Directors  of the
Company  as a result of proxy or  consent  solicitations  and a person who was a
participant  in such  solicitations  has stated  that such person (or any of its
affiliates  or  associates)  has taken,  intends to take or may consider  taking
actions  that would  result in such  person  becoming an  Acquiring  Person (the
existence of these circumstances being an "Adverse Change of Control"), then the
redemption  of the  Rights  will  require  the  approval  of a  majority  of the
Continuing Directors. "Continuing Director" means (i) any member of the Board of
Directors of the Company who is not an Acquiring  Person,  (or a representative,
affiliate or associate  of an Acquiring  Person),  and was a member of the Board
prior to the Record Date, or (ii) any person who  subsequently  becomes a member
of the Board who is not an Acquiring Person (or a  representative,  affiliate or
associate of an Acquiring Person),  if such Person's  nomination for election or
election to the Board is recommended or approved by a majority of the Continuing
Directors.

                  The  terms  of the  Rights  may be  amended  by the  Board  of
Directors  of the  Company  without  the  consent of the  holders of the Rights,
including an amendment to lower certain  thresholds  described  above  regarding
percentage  ownership  whereby any person or group of  affiliated  or associated
persons becomes an Acquiring Person,  provided,  however,  no such amendment may
adversely  affect the  interests of the holders of the Rights.  Until a Right is
exercised,  the holder thereof, as such, will have no rights as a stockholder of
the  Company,  including,  without  limitation,  the right to vote or to receive
dividends.

                  A copy of the Rights  Agreement,  between  the Company and the
Rights  Agent,  specifying  the  terms of the  Rights  (which  Rights  Agreement
includes as Exhibits,  the Form of Rights  Certificate and the Summary of Rights
to Purchase  Common Shares) is attached hereto as an Exhibit and is incorporated
herein by  reference.  The  forgoing  description  of the Rights is qualified by
reference to such Exhibit.

                                RIGHTS AGREEMENT

                  Rights  Agreement,  dated as of June  18,  1998  (the  "Rights
Agreement"  or  "Agreement"),  between  SPSS Inc., a Delaware  corporation  (the
"Company"), and Harris Trust and Savings Bank (the "Rights Agent").
                  WHEREAS,  The Board of Directors of the Company (the "Board of
Directors")  has authorized and declared a dividend of one common share purchase
right (a "Right") for each Common Share (as hereinafter  defined) of the Company
outstanding on June 30, 1998 (the "Record Date"),  each Right  representing  the
right to purchase one Common Share (as hereinafter defined),  upon the terms and
subject to the  conditions  herein set forth,  and has  further  authorized  and
directed  the issuance of one Right with respect to each Common Share that shall
become outstanding  between the Record Date and the earliest of the Distribution
Date,  the  Redemption  Date and the Final  Expiration  Date (as such  terms are
hereinafter defined).
                  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 have the meanings indicated:
                  (a) "Acquiring  Person" shall mean any Person (as such term is
hereinafter  defined) who or which,  together with all Affiliates and Associates
(as such terms are hereinafter  defined) of such Person, shall be the Beneficial
Owner (as such term is hereinafter  defined) of 15% or more of the Common Shares
of the  Company  then  outstanding,  but  shall not  include  the  Company,  any
Subsidiary (as such term is hereinafter defined) of the


<PAGE>



Company,  any  employee  benefit  plan of the Company or any  Subsidiary  of the
Company, or any entity holding Common Shares for or pursuant to the terms of any
such plan.  Notwithstanding the foregoing,  no Person shall become an "Acquiring
Person" as the result of an  acquisition  of Common Shares by the Company which,
by reducing the number of shares outstanding, increases the proportionate number
of shares  beneficially owned by such Person to 15% or more of the Common Shares
of the Company  then  outstanding;  provided,  however,  that if a Person  shall
become the  Beneficial  Owner of 15% or more of the Common Shares of the Company
then  outstanding by reason of share  purchases by the Company and shall,  after
such  share  purchases  by the  Company,  become  the  Beneficial  Owner  of any
additional Common Shares of the Company,  then such Person shall be deemed to be
an "Acquiring Person".  Notwithstanding the foregoing, if the Board of Directors
of the Company  determines in good faith that a Person who would otherwise be an
"Acquiring  Person",  as defined  pursuant to the  foregoing  provisions of this
paragraph  (a),  has  become  such  inadvertently,  and such  Person  divests as
promptly as practicable a sufficient number of Common Shares so that such Person
would no longer be an "Acquiring  Person," as defined  pursuant to the foregoing
provisions of this  paragraph (a), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement.
                  (b)  "Affiliate"  and  "Associate"  shall have the  respective
meanings  ascribed  to such  terms in Rule  12(b)-2  of the  General  Rules  and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), as in effect on the date of this Agreement.

                  (c) A Person  shall be deemed  the  "Beneficial  Owner" of and
shall be deemed to "beneficially own" any securities:
                           (i)       which such Person or any of such Person's 
                  Affiliates  or  Associates  beneficially  owns,  directly   or
                  indirectly;
                           (ii)  which  such  Person  or  any of  such  Person's
                  Affiliates  or Associates  directly or indirectly  has (A) the
                  right  to  acquire   (whether   such   right  is   exercisable
                  immediately or only after the passage of time) pursuant to any
                  agreement,  arrangement or understanding (other than customary
                  agreements  with and between  underwriters  and selling  group
                  members  with  respect  to a  bona  fide  public  offering  of
                  securities),  or  upon  the  exercise  of  conversion  rights,
                  exchange rights, rights (other than these Rights), warrants or
                  options, or otherwise;  provided, however, that a Person shall
                  not be deemed the Beneficial Owner of, or to beneficially own,
                  securities  tendered  pursuant to a tender or  exchange  offer
                  made by or on  behalf of such  Person or any of such  Person's
                  Affiliates or Associates  until such tendered  securities  are
                  accepted for  purchase or  exchange;  or (B) the right to vote
                  pursuant  to  any  agreement,  arrangement  or  understanding;
                  provided,  however,  that a Person  shall  not be  deemed  the
                  Beneficial  Owner of, or to beneficially  own, any security if
                  the  agreement,  arrangement  or  understanding  to vote  such
                  security (1) arises  solely from a revocable  proxy or consent
                  given to such Person in response to a public  proxy or consent
                  solicitation  made  pursuant to, and in accordance  with,  the
                  applicable  rules  and  regulations   promulgated   under  the
                  Exchange Act and (2) is not also

                  then reportable on Schedule 13D under the Exchange Act (or any
                  comparable or successor report); or
                           (iii)  which  are  beneficially  owned,  directly  or
                  indirectly,  by any other Person with which such Person or any
                  of such Person's  Affiliates or Associates  has any agreement,
                  arrangement or understanding  (other than customary agreements
                  with and between  underwriters  and selling group members with
                  respect to a bona fide public  offering of securities) for the
                  purpose of acquiring,  holding,  voting  (except to the extent
                  contemplated  by  the  proviso  to  Section   1(c)(ii)(B))  or
                  disposing of any securities of the Company.
Notwithstanding  anything in this  definition  of  Beneficial  Ownership  to the
contrary,  the phrase "then outstanding," when used with reference to a Person's
beneficial ownership of securities of the Company, shall mean the number of such
securities  then  issued  and  outstanding  together  with  the  number  of such
securities not then actually issued and  outstanding  which such Person would be
deemed to own beneficially  hereunder,  provided,  however, that nothing in this
subsection  (c) shall cause a Person  engaged in business as an  underwriter  of
securities  to be the  "Beneficial  Owner"  of,  or to  "beneficially  own," any
securities acquired through such Person's  participation in good faith in a firm
commitment  underwriting  until the  expiration  of forty days after the date of
such acquisition.
                  (d) "Business Day" shall mean any day other than a Saturday, a
Sunday,  or a day on which banking  institutions  in Illinois are  authorized or
obligated by law or executive order to close.

                  (e)  "Close of  business"  on any given  date  shall mean 5:00
P.M., Chicago, Illinois time, on such date; provided, however, that if such date
is not a Business Day it shall mean 5:00 P.M.,  Chicago,  Illinois  time, on the
next succeeding Business Day.
                  (f) "Common  Shares"  when used with  reference to the Company
shall mean the shares of common stock, par value $.01 per share, of the Company.
"Common  Shares"  when used with  reference to any Person other than the Company
shall mean the capital stock (or equity interest) with the greatest voting power
of such other Person or, if such other Person is a Subsidiary of another Person,
the Person or Persons which ultimately control such first-mentioned Person.
                  (g)  "Distribution  Date"  shall have the meaning set forth in
Section 3 hereof.  
                  (h) "Final  Expiration Date" shall have the meaning set forth 
in Section 7 hereof.
                  (i) "Person"  shall mean any  individual,  firm,  partnership,
corporation  or other  entity,  and shall  include any  successor  (by merger or
otherwise) of such entity.
                  (j)      "Redemption Date" shall have the meaning set forth in

                  Section 2.  Appointment  of Rights Agent.  The Company  hereby
appoints the Rights Agent to act as agent for the Company and the holders of the
Rights  (who,  in  accordance  with  Section  3  hereof,   shall  prior  to  the
Distribution  Date also be the holders of the Common Shares) 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 desirable.
                  Section 3. Issue of Right Certificates.  (a) Until the earlier
of (i) the  tenth  day  after  the  Shares  Acquisition  Date or (ii) the  tenth
business day (or such later date as may be  determined by action of the Board of
Directors prior to such time as any Person becomes an Acquiring  Person provided
that, if such determination  occurs on or after the date of an Adverse Change of
Control as that term is defined in  Section  23,  hereto,  then such date may be
extended  only if there are  Continuing  Directors (as  hereinafter  defined) in
office  and such  extension  is  authorized  by a  majority  of such  Continuing
Directors)  after the date of the  commencement  by any Person  (other  than the
Company, any Subsidiary of the Company, any employee benefit plan of the Company
or of any  Subsidiary of the Company or any entity  holding Common Shares for or
pursuant to the terms of any such plan) of, or of the first public  announcement
of the  intention of any Person (other than the Company,  any  Subsidiary of the
Company,  any employee  benefit plan of the Company or of any  Subsidiary of the
Company or any entity  holding Common Shares for or pursuant to the terms of any
such

plan) to commence,  a tender or exchange offer the  consummation  of which would
result in any Person becoming the Beneficial Owner of Common Shares  aggregating
15% or more of the then  outstanding  Common Shares or any events the Continuing
Directors shall deem constitute an Adverse Change of Control (including any such
date which is after the date of this  Agreement and prior to the issuance of the
Rights;  the earlier of such dates being herein referred to as the "Distribution
Date"),  (x) the Rights will be evidenced  (subject to the provisions of Section
3(b) hereof) by the  certificates  for Common Shares  registered in the names of
the  holders  thereof  (which  certificates  shall  also be  deemed  to be Right
Certificates)  and not by  separate  Right  Certificates,  and (y) the  right to
receive Right  Certificates  will be  transferable  only in connection  with the
transfer of Common Shares. As soon as practicable  after the Distribution  Date,
the Company will prepare and execute, the Rights Agent will countersign, and the
Company will send or cause to be sent (and the Rights Agent will,  if requested,
send at the expense of the  Company) by  first-class,  insured,  postage-prepaid
mail,  to each record holder of Common Shares as of the close of business on the
Distribution  Date,  at the address of such  holder  shown on the records of the
Company, a Right  Certificate,  in substantially the form of Exhibit A hereto (a
"Right Certificate"),  evidencing one Right for each Common Share so held. As of
the  Distribution  Date,  the  Rights  will be  evidenced  solely by such  Right
Certificates. In the event that an adjustment in the number of Rights per Common
Share  has  been  made  pursuant  to  Section  11(i)  hereof,  at  the  time  of
distribution of the Right  Certificates,  the Company may make the necessary and
appropriate  rounding  adjustments  (in accordance with Section 14(a) hereof) so
that Right Certificates representing

                                      - 7 -

<PAGE>



only whole  numbers of Rights  are  distributed  and cash is paid in lieu of any
fractional Rights pursuant to Section 14, hereof.
                  (b) On the Record Date, or as soon as practicable  thereafter,
the Company will send a copy of a Summary of Rights to Purchase  Common  Shares,
in  substantially  the form of Exhibit B hereto (the  "Summary of  Rights"),  by
first-class,  postage-prepaid mail, to each record holder of Common Shares as of
the close of business on the Record Date, at the address of such holder shown on
the records of the  Company.  With  respect to  certificates  for Common  Shares
outstanding as of the Record Date, until the Distribution  Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together  with a copy of the  Summary  of  Rights  attached  thereto.  Until the
Distribution Date (or the earlier of the Redemption Date or the Final Expiration
Date),  the  surrender  for  transfer  of  any  certificate  for  Common  Shares
outstanding on the Record Date,  with or without a copy of the Summary of Rights
attached  thereto,  shall also constitute the transfer of the Rights  associated
with the Common Shares represented thereby.
                  (c) Rights  shall be issued in  respect  of all Common  Shares
which  are  issued  after  the  Record  Date  but  prior to the  earlier  of the
Distribution Date, the Redemption Date, the Final Expiration Date, or in certain
circumstances provided in Section 22, after the Distribution Date.  Certificates
for Common  Shares  which become  outstanding  (including,  without  limitation,
reacquired Common Shares referred to in the last sentence of this paragraph (c))
after the Record Date but prior to the earliest of the  Distribution  Date,  the
Redemption  Date or the Final  Expiration  Date shall have impressed on, printed
on, written on or otherwise affixed to them the following legend:

                  This certificate also evidences and entitles the holder hereof
                  to certain rights as set forth in a Rights  Agreement  between
                  SPSS Inc. and Harris Trust and Savings Bank,  dated as of June
                  18,  1998  (the  "Rights  Agreement"),  the terms of which are
                  hereby incorporated herein by reference and a copy of which is
                  on file at the principal  executive offices of SPSS Inc. Under
                  certain  circumstances,  as set forth in the Rights Agreement,
                  such Rights will be  evidenced  by separate  certificates  and
                  will no longer be  evidenced  by this  certificate.  SPSS Inc.
                  will  mail to the  holder  of this  certificate  a copy of the
                  Rights  Agreement  without  charge after  receipt of a written
                  request therefor. Under certain circumstances, as set forth in
                  the Rights Agreement,  Rights issued to any Person who becomes
                  an Acquiring  Person (as defined in the Rights  Agreement) may
                  become null and void.

With respect to such  certificates  containing the foregoing  legend,  until the
Distribution  Date, the Rights associated with the Common Shares  represented by
such  certificates  shall  be  evidenced  by such  certificates  alone,  and the
surrender  for  transfer  of any such  certificate  shall  also  constitute  the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Company  purchases  or acquires  any Common  Shares after the
Record Date but prior to the Distribution  Date, any Rights associated with such
Common  Shares shall be deemed  cancelled  and retired so that the Company shall
not be entitled to exercise any Rights  associated  with the Common Shares which
are no longer outstanding.
                  Section 4. Form of Right Certificates.  The Right Certificates
(and the forms of election to purchase  Common  Shares and of  assignment  to be
printed on the reverse  thereof)  shall be  substantially  the same as Exhibit A
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  on which the Rights may from time to time be listed,  or to conform to
usage. Subject to the

                                      - 9 -

<PAGE>



provisions  of Section 22  hereof,  the Right  Certificates  shall  entitle  the
holders  thereof to purchase  such number of Common Shares as shall be set forth
therein at the price per Common Share set forth therein (the "Purchase  Price"),
but the number of such Common Shares and the Purchase  Price shall be subject to
adjustment as provided herein.
                  Section  5.  Countersignature  and  Registration.   The  Right
Certificates  shall be executed on behalf of the Company by its  Chairman of the
Board of Directors,  its Chief Executive Officer, its President, any of its Vice
Presidents, or its Treasurer,  either manually or by facsimile signature,  shall
have affixed  thereto the Company's  seal or a facsimile  thereof,  and shall be
attested by the  Secretary  or an Assistant  Secretary  of the  Company,  either
manually or by facsimile  signature.  The Right  Certificates  shall be manually
countersigned  by the Rights Agent and shall not be valid for any purpose unless
countersigned.  In case any  officer of the Company who shall have signed any of
the Right  Certificates  shall cease to be such  officer of the  Company  before
countersignature  by the Rights  Agent and issuance and delivery by the Company,
such Right Certificates,  nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the person who signed such Right  Certificates had not ceased to be such officer
of the Company; and any Right Certificate may be signed on behalf of the Company
by  any  person  who,  at the  actual  date  of  the  execution  of  such  Right
Certificate,  shall  be a proper  officer  of the  Company  to sign  such  Right
Certificate,  although at the date of the execution of this Rights Agreement any
such person was not such an officer.
                  Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its principal  office,  books for registration and transfer
of the Right Certificates issued

                                     - 10 -

<PAGE>



hereunder.  Such books  shall  show the names and  addresses  of the  respective
holders of the Right Certificates, the number of Rights evidenced on its face by
each of the Right Certificates and the date of each of the Right Certificates.
                  Section 6.  Transfer  Split Up,  Combination  and  Exchange of
Right Certificates: Mutilated, Destroyed, Lost or Stolen Right Certificates. (a)
Subject to the provisions of Section 7(e),  Section 11 and Section 14 hereof, at
any time after the close of business on the  Distribution  Date, and at or prior
to the close of  business  on the  earlier of the  Redemption  Date or the Final
Expiration Date, any Right Certificate or Right  Certificates  (other than Right
Certificates  representing  Rights  that have  become  void  pursuant to Section
11(a)(ii) hereof or that have been exchanged  pursuant to Section 24 hereof) may
be transferred,  split up, combined or exchanged,  for another Right Certificate
or Right Certificates, entitling the registered holder to purchase a like number
of Common  Shares (or other  securities  or  assets,  as the case may be) as the
Right Certificate or Right Certificates surrendered then entitled such holder to
purchase.  Any  registered  holder  desiring to transfer,  split up,  combine or
exchange any Right Certificate or Right  Certificates shall make such request in
writing delivered to the Rights Agent, and shall surrender the Right Certificate
or Right Certificates to be transferred, split up, combined or exchanged, at the
principal  office of the Rights Agent.  Neither the Rights Agent nor the Company
shall be obligated to take any action whatsoever with respect to the transfer of
any such surrendered  Right  Certificate  until the registered holder shall have
completed and signed the  certificate  contained in the form of  assignment  and
certification  thereto on the reverse side of such Right  Certificate  and shall
have provided such additional  evidence of the identity of the Beneficial  Owner
(or former Beneficial Owner)

                                     - 11 -

<PAGE>



or  Affiliates or Associates  thereof as the Company shall  reasonably  request.
Thereupon  the Rights  Agent shall  subject to Section 7, Section 11 and Section
14,  countersign and deliver to the person entitled thereto a Right  Certificate
or Right  Certificates,  as the case may be, as so  requested.  The  Company may
require payment of a sum sufficient to cover any tax or governmental charge that
may be  imposed  in  connection  with any  transfer,  split up,  combination  or
exchange of Right Certificates.
                  (b)  Upon  receipt  by the  Company  and the  Rights  Agent of
evidence  reasonably  satisfactory  to them of the loss,  theft,  destruction or
mutilation of a Right  Certificate,  and, in case of loss, theft or destruction,
of indemnity or security reasonably  satisfactory to them, and, at the Company's
request,  reimbursement  to the Company and the Rights  Agent of all  reasonable
expenses  incidental  thereto,  and  upon  surrender  to the  Rights  Agent  and
cancellation  of the Right  Certificate if mutilated,  the Company will make and
deliver a new Right  Certificate  of like tenor to the Rights Agent for delivery
to the  registered  holder in lieu of the  Right  Certificate  so lost,  stolen,
destroyed or mutilated.
                  Section 7. Exercise of Rights; Purchase Price, Expiration Date
of Rights.  (a) The registered  holder of any Right Certificate may exercise the
Rights  evidenced  thereby (except as otherwise  provided herein) in whole or in
part at any time  after  the  Distribution  Date  upon  surrender  of the  Right
Certificate,  with the form of election to purchase on the reverse  side thereof
duly executed,  to the Rights Agent at the principal office of the Rights Agent,
together  with payment of the  Purchase  Price for each Common Share as to which
the  Rights  are  exercised,  at or prior to the  earliest  of (i) the  close of
business on June 18, 2008 (the "Final Expiration Date"),  (ii) the time at which
the Rights are redeemed as provided in

                                     - 12 -

<PAGE>



Section  23 hereof  (the  "Redemption  Date"),  or (iii) the time at which  such
Rights are exchanged as provided in Section 24 hereof.
                  (b) The  Purchase  Price  for each  Common  Share  purchasable
pursuant  to the  exercise  of a Right  shall  initially  be $175,  and shall be
subject to  adjustment  from time to time as provided in Section 11 or 13 hereof
and shall be  payable  in  lawful  money of the  United  States  of  America  in
accordance with paragraph (c) below.
                  (c)  Upon   receipt  of  a  Right   Certificate   representing
exercisable  Rights,  with the  form of  election  to  purchase  duly  executed,
accompanied  by payment of the Purchase Price for the shares to be purchased and
an amount equal to any applicable transfer tax required to be paid by the holder
of such Right  Certificate  in  accordance  with  Section 9 hereof by  certified
check,  cashier's check or money order payable to the order of the Company,  the
Rights  Agent  shall,  subject  to Section  20(j),  thereupon  promptly  (i) (A)
requisition  from any transfer agent of the Common Shares  certificates  for the
number of Common  Shares to be  purchased  and the  Company  hereby  irrevocably
authorizes  its  transfer  agent  to  comply  with  all  such  requests,  or (B)
requisition  from the depositary  agent depositary  receipts  representing  such
number of Common Shares as are to be purchased (in which case  certificates  for
the  Common  Shares  represented  by such  receipts  shall be  deposited  by the
transfer  agent with the  depositary  agent) and the Company  hereby directs the
depositary agent to comply with such request, (ii) when appropriate, requisition
from the Company the amount of cash to be paid in lieu of issuance of fractional
shares in  accordance  with  Section  14  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 Right Certificate, registered in

                                     - 13 -

<PAGE>



such  name  or  names  as may  be  designated  by  such  holder  and  (iv)  when
appropriate,  after  receipt,  deliver  such  cash to or upon  the  order of the
registered  holder  of such  Right  Certificate.  In the event  the  Company  is
obligated to issue other securities  (including Common Shares) of the Company or
distribute  other property  pursuant to Section 11 hereof,  the Company will use
its  best  efforts  to  make  all  arrangements  necessary  so that  such  other
securities or property are available for  distribution  by the Rights Agent,  if
and when appropriate.
                  (d) In case the  registered  holder of any  Right  Certificate
shall  exercise  less  than  all  the  Rights  evidenced  thereby,  a new  Right
Certificate  evidencing  Rights  equivalent to the Rights remaining  unexercised
shall be issued  by the  Rights  Agent to the  registered  holder of such  Right
Certificate  or to his duly  authorized  assigns,  subject to the  provisions of
Section 14 hereof.
                  (e)   Notwithstanding   anything  to  the   contrary  in  this
Agreement,  after the first  occurrence of any event under Section  11(a)(ii) or
Section 13 hereunder,  any Rights beneficially owned by (i) any Acquiring Person
(or any Associate or Affiliate of an Acquiring Person),  (ii) a transferee of an
Acquiring  Person (or any  Associate or Affiliate of an Acquiring  Person) which
becomes a  transferee  after  the  Acquiring  Person  becomes  such,  or (iii) a
transferee of an Acquiring Person (or any Associate or Affiliate of an Acquiring
Person) who becomes a transferee  prior to or  concurrently  with the  Acquiring
Person  becoming such and receives such Rights pursuant to either (A) a transfer
(whether or not for  consideration)  from the Acquiring Person (or any Associate
or Affiliate of such  Acquiring  Person) to holders of equity  interests in such
Acquiring Person (or of such Associate or

                                     - 14 -

<PAGE>



Affiliate)  or to any Person with whom the Acquiring  Person has any  agreement,
arrangement or understanding regarding the transferred Rights, or (B) a transfer
that the Board of  Directors  of the Company has  determined  is part of a plan,
arrangement  or  understanding  which has as a  primary  purpose  or effect  the
avoidance  of this  Section  7(e),  shall be null and void  without  any further
action,  and no holder of such  Rights  shall  have any rights  whatsoever  with
respect  to such  Rights,  whether  under any  provision  of this  Agreement  or
otherwise.
                  Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise,  transfer, split
up,  combination or exchange  shall,  if surrendered to the Company or to any of
its agents,  be delivered to the Rights Agent for  cancellation  or in cancelled
form, or, if  surrendered to the Rights Agent,  shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Rights Agreement.  The Company shall deliver to
the Rights Agent for cancellation and retirement,  and the Rights Agent shall so
cancel and retire,  any other  Right  Certificate  purchased  or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all  cancelled  Right  Certificates  to the  Company,  or shall,  at the written
request of the Company,  destroy such cancelled Right Certificates,  and in such
case shall deliver a certificate of destruction thereof to the Company.
                  Section 9.  Availability of Common Shares.  (a) Subject to the
Company's  rights  under  Section  11(a)(iii)  hereof to  otherwise  fulfill its
obligations hereunder, the Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued  Common Shares or
any Common Shares held in its treasury, the number of Common Shares that will be
sufficient to permit the exercise in full of all

                                     - 15 -

<PAGE>



outstanding  Rights in accordance with Section 7; provided,  however,  that such
action  need not be taken with  respect to Common  Shares (or other  securities)
issuable  upon exercise of the Rights until after such time as the Rights become
exercisable,  and with respect to Common Shares (or other  securities)  issuable
upon occurrence of an event under Section 11(a)(ii) or Section 13, hereunder.
                  (b) The  Company  shall use its best  efforts to (i) file,  as
soon as is practicable following the earliest date after the first occurrence of
an event  under  Section  11(a)(ii)  or  Section  13  hereunder,  in  which  the
consideration  to be delivered  by the Company  upon  exercise of the Rights has
been determined in accordance with this Agreement,  or as soon as is required by
law  following  the  Distribution  Date,  as the  case  may be,  a  registration
statement under the Securities Act of 1933, as amended (the  "Securities  Act"),
with respect to the  securities  purchasable  upon  exercise of the Rights on an
appropriate form, (ii) cause such registration  statement to become effective as
soon as  practicable  after  such  filing  and  (iii)  cause  such  registration
statement  to remain  effective  (with a  prospectus  at all times  meeting  the
requirements  of the  Securities  Act)  until the  earlier of (A) the date as of
which the Rights are no longer  exercisable for such securities or (B) the Final
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  and other  appropriate  jurisdictions  in  connection  with the
exercisability of the Rights. The Company may temporarily  suspend, for a period
of time not to exceed ninety (90) days after the date set forth in clause (i) of
the first sentence of this paragraph,  the exercisability of the Rights in order
to  prepare  and file  such  registration  statement  and  permit  it to  become
effective and to take such actions under such

                                     - 16 -

<PAGE>



other securities or blue sky laws and permit them to become effective.  Upon any
such suspension,  the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement   at  such  time  as  the   suspension  is  no  longer  in  effect.
Notwithstanding  any  provision of this  Agreement to the  contrary,  the Rights
shall not be exercisable in any  jurisdiction if the requisite  qualification in
such jurisdiction shall not have been obtained or the exercise thereof shall not
be permitted  under  applicable law or a registration  statement  shall not have
been declared effective.
                  (c) The  Company  covenants  and agrees  that it will take all
such  action as may be  necessary  to  ensure  that all  Common  Shares 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 shares.
                  (d) The Company further covenants and agrees that,  subject to
Sections 6 and 7(c),  it will pay when due and  payable  any and all federal and
state transfer taxes and charges which may be payable in respect of the issuance
or  delivery  of the  Right  Certificates  or of any  Common  Shares  (or  other
securities  or  property)  upon the exercise of Rights.  The Company  shall not,
however,  be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right  Certificates  to a person other than,  or the
issuance or delivery  of  certificates  or  depositary  receipts  for the Common
Shares  (or other  securities  or  property)  in a name  other than that of, the
registered  holder of the Right Certificate  evidencing  Rights  surrendered for
exercise or to issue or to deliver any  certificates or depositary  receipts for
Common Shares (or other securities or property) upon the exercise of

                                     - 17 -

<PAGE>



any Rights  until any such tax shall have been paid (any such tax being  payable
by the holder of such Right  Certificate  at the time of  surrender) or until it
has been established to the Company's  reasonable  satisfaction that no such tax
is due.
                  Section 10. Common  Shares  Record Date.  Each person in whose
name any certificate for Common Shares (or other  securities) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of the Common Shares (or other  securities)  represented  thereby on, and
such  certificate  shall be  dated,  the date upon  which the Right  Certificate
evidencing  such Rights was duly  surrendered  and payment of the Purchase Price
(and any applicable  transfer taxes) was made;  provided,  however,  that if the
date of such  surrender  and payment is a date upon which the Common  Shares (or
other securities) transfer books of the Company are closed, such person shall be
deemed to have become the record holder of such shares on, and such  certificate
shall be dated, the next succeeding  Business Day on which the Common Shares (or
other securities)  transfer books of the Company are open. Prior to the exercise
of the Rights evidenced thereby,  the holder of a Right Certificate shall not be
entitled to any rights of a holder of Common  Shares (or other  securities)  for
which the Rights shall be exercisable,  including, without limitation, the right
to  vote,  to  receive  dividends  or other  distributions  or to  exercise  any
preemptive  rights,  and shall not be  entitled  to  receive  any  notice of any
proceedings of the Company, except as provided herein.
                  Section 11.  Adjustment of Purchase Price, Number of Shares or
Number  of Rights.  The  Purchase  Price,  the  number of any kind of securities
covered by each Right and

                                     - 18 -

<PAGE>



the number of Rights  outstanding are subject to adjustment from time to time as
provided in this Section 11.
                  (a) (i) In the event the  Company  shall at any time after the
date of this  Agreement (A) declare a dividend on the Common  Shares  payable in
Common Shares,  (B) subdivide the  outstanding  Common  Shares,  (C) combine the
outstanding  Common  Shares into a smaller  number of Common Shares or (D) issue
any shares of its  capital  stock in a  reclassification  of the  Common  Shares
(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), the Purchase Price
in effect at the time of the record date for such  dividend or of the  effective
date of such subdivision,  combination or  reclassification,  and the number and
kind of shares of capital stock issuable on such date, shall be  proportionately
adjusted  so that the  holder of any Right  exercised  after  such time shall be
entitled to receive  the  aggregate  number and kind of shares of capital  stock
which, if such Right had been exercised  immediately prior to such date and at a
time  when the  Common  Shares  (or  other  capital  stock,  as the case may be)
transfer books of the Company were open,  such holder would have owned upon such
exercise and been entitled to receive by virtue of such  dividend,  subdivision,
combination or reclassification;  provided,  however, that in no event shall the
consideration  to be paid  upon  the  exercise  of one  Right  be less  than the
aggregate par value of the shares of capital stock of the Company  issuable upon
exercise of one Right. If an event occurs that would require an adjustment under
both this Section 11(a)(i) and Section 11(a)(ii), the adjustment provided for in
this Section 11(a)(i)

                                     - 19 -

<PAGE>



shall be in  addition  to, and shall be made prior to, any  adjustment  required
pursuant to Section 11(a)(ii).
                           (ii)     Subject to Section 24 of this Agreement, in 
the event any Person is or becomes an Acquiring  Person,  then, each holder of a
Right,  except as provided below and in Section 7(e),  shall  thereafter  have a
right to receive,  upon  exercise  thereof at a price equal to the then  current
Purchase  Price  multiplied  by the number of Common Shares for which a Right is
then exercisable,  in accordance with the terms of this Agreement and in lieu of
Common  Shares,  such number of Common  Shares of the Company as shall equal the
result obtained by (x) multiplying the then current Purchase Price by the number
of Common Shares for which a Right is then exercisable and dividing that product
by (y) 50% of the then current per share market  price of the  Company's  Common
Shares  (determined  pursuant  to  Section  11(d)  hereof)  on the  date  of the
occurrence of such event (such number of shares is herein called the "Adjustment
Shares").  In the event that any Person shall become an Acquiring Person and the
Rights shall then be  outstanding,  the Company  shall not take any action which
would eliminate or diminish the benefits  intended to be afforded by the Rights.

     From and after the  occurrence  of such event,  any Rights that are or were
acquired or  beneficially  owned by any  Acquiring  Person (or any  Associate or
Affiliate of such Acquiring  Person) shall be void and any holder of such Rights
shall  thereafter  have no right to exercise  such Rights under any provision of
this Agreement.  No Right Certificate shall be issued pursuant to Section 3 that
represents Rights  beneficially  owned by an Acquiring Person whose Rights would
be void  pursuant  to the  preceding  sentence  or any  Associate  or  Affiliate
thereof;  no Right  Certificate shall be issued at any time upon the transfer of
any Rights to an

                                     - 20 -

<PAGE>



Acquiring  Person whose Rights would be void pursuant to the preceding  sentence
or any  Associate  or  Affiliate  thereof or to any  nominee  of such  Acquiring
Person,  Associate  or  Affiliate;  and any Right  Certificate  delivered to the
Rights  Agent for  transfer to an  Acquiring  Person  whose Rights would be void
pursuant to the preceding sentence shall be cancelled. The Company shall use all
reasonable  efforts to insure that the provisions of this subsection and Section
7(e) hereof as complied  with,  but shall have no  liability  to any holder of a
Rights  Certificate  or other  Persons  as a result of its  failure  to make any
determination  with  respect to an  Acquiring  Person or any of its  Affiliates,
Associates or transferees hereunder.
                           (iii) In the event that after the  Distribution  Date
or, in the case of a Section 11(a)(ii) Event after the date of the occurrence of
such Section 11(a)(ii) Event, the number of Common Shares which is authorized by
the Company's  articles 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,  the Company shall:  (A) determine
the  excess of (1) the  value of the  Common  Shares,  or  Adjustment  Shares in
accordance  with  Section  11(a)(ii),  as the  case  may be,  issuable  upon the
exercise of a Right (the  "Current  Value")  over (2) the  Purchase  Price (such
excess is herein called the "Spread"),  and (B) with respect to each Right, make
adequate  provision to substitute for the Common Shares, or Adjustments  Shares,
as the case may be, upon  exercise of the Rights,  (1) cash,  (2) a reduction in
the Purchase  Price,  (3) Common Shares of the same or different  class or other
equity  securities of the Company  (including,  without  limitation,  shares, or
units of shares,  of preferred stock which the Board of Directors of the Company
has deemed to have  substantially the same economic value as Common Shares (such
shares or units of shares of

                                     - 21 -

<PAGE>



preferred stock are referred to herein as "common share 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 thirty (30) days following the Distribution  Date, or in
the case of a Section 11(a)(ii) Event the later of (x) the first occurrence of a
Section  11(a)(ii)  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 "Section  11(a)(ii)  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,  Common Shares (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
Common  Shares could be  authorized  for issuance  upon  exercise in full of the
Rights, the thirty (30) day period set forth above may be extended to the extent
necessary,   but  not  more  than  one  hundred  twenty  (120)  days  after  the
Distribution  Date or the Section 11(a)(ii) Trigger Date, as the case may be, in
order that the Company may seek  shareholder  approval for the  authorization of
such additional  shares (such period,  as it may be extended,  the "Substitution
Period").  To the extent that the Company  determines that some action should 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

                                     - 22 -

<PAGE>



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  securities 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  exercisability  of  the  Rights  has  been
temporarily  suspended,  as well as a public  announcement  at such  time as the
suspension is no longer in effect. For purposes of this Section 11(a)(iii),  the
value of the Common  Shares  shall be the  current  per share  market  price per
Common  Share (as  defined in  Section  11(d)) on the  Distribution  Date or the
Section 11(a)(ii) Trigger Date, as the case may be, and the value of any "common
share equivalent" shall be deemed to have the same value as the Common Shares 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 Common  Shares
entitling them (for a period  expiring within 45 calendar days after such record
date) to  subscribe  for or purchase  Common  Shares (or shares  having the same
rights,  privileges  and  preferences as the Common Shares  ("equivalent  common
shares")) or securities  convertible  into Common  Shares or  equivalent  common
shares at a price per  Common  Share or  equivalent  common  share (or  having a
conversion  price per share,  if a security  convertible  into Common  Shares or
equivalent  common  shares) less than the then current per share market price of
the  Common  Shares  (as  defined in Section  11(d)) 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 Common

                                     - 23 -

<PAGE>



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

                                     - 24 -

<PAGE>



cash dividend or a dividend payable in Common Shares) 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 then  current per share  market
price of the Common  Shares on such record date,  less the fair market value (as
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose
determination  shall be described in a statement filed with the Rights Agent) of
the portion of the assets or evidences of  indebtedness  so to be distributed or
of such subscription  rights or warrants  applicable to one Common Share and the
denominator  of which shall be such current per share market price of the Common
Shares;  provided,  however, that in no event shall the consideration to be paid
upon the  exercise  of one  Right be less  than the  aggregate  par value of the
shares of capital  stock of the Company to be issued upon exercise of one Right.
Such  adjustments  shall be made  successively  whenever  such a record  date is
fixed;  and in the event that such  distribution  is not so made,  the  Purchase
Price shall again be  adjusted to be the  Purchase  Price which would then be in
effect if such record date had not been fixed.
                  (d) (i) For the  purpose  of any  computation  hereunder,  the
"current per share market price" of any security (a  "Security"  for the purpose
of this  Section  11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the thirty (30)  consecutive
Trading Days (as such term is  hereinafter  defined)  immediately  prior to such
date;  provided,  however,  that in the event that the current per share  market
price of the Security is determined  during a period  following the announcement
by the  issuer  of such  Security  of (A) a  dividend  or  distribution  on such
Security payable in shares of such

                                     - 25 -

<PAGE>



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

                           (ii)    For the purpose of any computation hereunder,
the "current per share market price" of the Common Shares shall be determined in
accordance with the method set forth in Section  11(d)(i).  If the Common Shares
are not publicly  traded,  the  "current  per share market  price" of the Common
Shares shall be conclusively  deemed to be the current per share market price of
the Common  Shares as  determined  pursuant to Section  11(d)(i)  (appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring after the date hereof).  If the Common Shares are not publicly held or
so listed or traded,  "current per share market price" shall mean the fair value
per share as  determined in good faith by the Board of Directors of the Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent.  
     (e) No  adjustment  in the  Purchase  Price shall be  required  unless such
adjustment  would require an increase or decrease of at least 1% in the Purchase
Price;  provided,  however, that any adjustments which by reason of this Section
11(e) are not  required  to be made  shall be  carried  forward  and taken  into
account in any subsequent  adjustment.  All  calculations  under this Section 11
shall be made to the  nearest  cent or to the nearest  one  ten-thousandth  of a
Common   Share  or  of  any  other  share  or  security  as  the  case  may  be.
Notwithstanding  the  first  sentence  of this  Section  11(e),  any  adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the  transaction  which requires such  adjustment or (ii)
the date of the  expiration  of the right to exercise  any  Rights.  
     (f) If as a result of an adjustment  made pursuant to Section 11(a) hereof,
the holder of any Right  thereafter  exercised  shall become entitled to receive
any shares of

                                     - 27 -

<PAGE>



capital stock of the Company other than Common Shares,  thereafter the number of
such other shares so  receivable  upon exercise of any Right shall be subject to
adjustment  from time to time in a manner and on terms as nearly  equivalent  as
practicable  to the provisions  with respect to the shares  contained in Section
11(a),  (b), and (c) inclusive,  and the provisions of Sections 7, 9, 10, 13 and
14 with respect to the Common Shares shall apply on like terms to any such other
shares.
                  (g) All Rights originally issued by the Company  subsequent to
any adjustment  made to the Purchase Price hereunder shall evidence the right to
purchase,   at  the  adjusted  Purchase  Price,  the  number  of  Common  Shares
purchasable from time to time hereunder upon exercise of the Rights, all subject
to further adjustment as provided herein.
                  (h) Unless the Company  shall have  exercised  its election as
provided in Section  11(i),  upon each  adjustment  of the  Purchase  Price as a
result  of  the  calculations  made  in  Sections  11(b)  and  (c),  each  Right
outstanding  immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of a
Common Shares  (calculated to the nearest one  one-millionth  of a Common Share)
obtained by (i)  multiplying  (x) the number of Common Shares 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 substitution
for any adjustment in the number of Common Shares  purchasable upon the exercise
of a Right. Each of the Rights

                                     - 28 -

<PAGE>



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

                  (j)  Irrespective  of any adjustment or change in the Purchase
Price or the number of Common  Shares  issuable upon the exercise of the Rights,
the Right Certificates theretofore and thereafter issued may continue to express
the Purchase  Price and the number of Common Shares which were  expressed in the
initial Right Certificates issued hereunder.
                  (k) Before  taking any action that would  cause an  adjustment
reducing  the  Purchase  Price  below the then par value,  if any, of the Common
Shares  issuable  upon  exercise  of the  Rights,  the  Company  shall  take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
Common Shares at such adjusted Purchase Price.
                  (l) In any case in which this Section 11 shall require that an
adjustment  in the  Purchase  Price be made  effective as of a record date for a
specified  event,  the Company may elect to defer until the  occurrence  of such
event the issuing to the holder of any Right exercised after such record date of
the Common Shares and other capital stock or securities of the Company,  if any,
issuable  upon such  exercise over and above the Common Shares and other capital
stock or securities of the Company,  if any,  issuable upon such exercise on the
basis of the  Purchase  Price in  effect  prior  to such  adjustment;  provided,
however,  that the  Company  shall  deliver  to such  holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.
                  (m)   Anything   in   this   Section   11  to   the   contrary
notwithstanding,  the Company  shall be entitled to make such  reductions in the
Purchase  Price,  in addition to those  adjustments  expressly  required by this
Section 11, as and to the extent that it in its sole

                                     - 30 -

<PAGE>



discretion  shall determine to be advisable in order that any (i)  consolidation
or subdivision of the Common Shares, (ii) issuance wholly for cash of any Common
Shares at less than the current market price,  (iii) issuance wholly for cash of
Common  Shares  or  securities  which by their  terms  are  convertible  into or
exchangeable  for Common  Shares,  (iv)  dividends on Common  Shares  payable in
Common  Shares or (v)  issuance  of rights,  options  or  warrants  referred  to
hereinabove  in Section  11(b),  hereafter made by the Company to holders of its
Common Shares shall not be taxable to such stockholders.
                  (n) In the  event  that at any  time  after  the  date of this
Agreement and prior to the  Distribution  Date, the Company shall (i) declare or
pay any dividend on the Common Shares  payable in Common Shares or (ii) effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or otherwise  than by payment of  dividends in Common  Shares)
into a greater or lesser number of Common Shares,  then in any such case (A) the
number of Common  Shares  purchasable  after such event upon proper  exercise of
each Right shall be  determined  by  multiplying  the number of Common Shares so
purchasable  immediately  prior to such event by a fraction,  the  numerator  of
which is the number of Common Shares  outstanding  immediately before such event
and the  denominator  of  which  is the  number  of  Common  Shares  outstanding
immediately after such event, and (B) each Common Share outstanding  immediately
after such event  shall have  issued  with  respect to it that  number of Rights
which each Common Share  outstanding  immediately prior to such event had issued
with respect to it. The adjustments  provided for in this Section 11(n) shall be
made  successively  whenever  such a  dividend  is  declared  or  paid or such a
subdivision, combination or consolidation is effected.

                  Section 12.  Certificate of Adjusted  Purchase Price or Number
of  Shares.  Whenever  an  adjustment  is made as  provided  in Section 11 or 13
hereof, the Company shall promptly (a) prepare a certificate  setting forth such
adjustment,  and a brief statement of the facts  accounting for such adjustment,
(b) file  with the  Rights  Agent and with each  transfer  agent for the  Common
Shares a copy of such  certificate  and (c) mail a brief summary thereof to each
holder of a Right  Certificate in accordance with Section 25 hereof.  The Rights
Agent shall be fully  protected  in relying on any such  certificate  and on any
adjustment  therein  contained,  and shall not be obligated or  responsible  for
calculating any adjustment,  nor shall it be deemed to have knowledge of such an
adjustment unless and until it shall have received such certificate.
                  Section  13.  Consolidation,  Merger  or Sale or  Transfer  of
Assets or Earning Power. (a) In the event,  directly or indirectly,  at any time
after a Person has become an Acquiring Person, (x) the Company shall consolidate
with, or merge with and into, any other Person, (y) any Person shall consolidate
with the  Company,  or merge with and into the Company and the Company  shall be
the continuing or surviving  corporation of such merger and, in connection  with
such merger, all or part of the Common Shares shall be changed into or exchanged
for stock or other  securities  of any other  Person (or the Company) or cash or
any other property,  or (z) the Company shall sell or otherwise transfer (or one
or more of its Subsidiaries  shall sell or otherwise  transfer),  in one or more
transactions,  assets or earning power  aggregating 50% or more of the assets or
earning  power of the  Company  and its  Subsidiaries  (taken as a whole) to any
other  Person  other  than  the  Company  or one  or  more  of its  wholly-owned
Subsidiaries, then, and in each such case, proper provision shall be made

                                     - 32 -

so that (i) each holder of a Right (except as otherwise  provided  herein) shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to the then current Purchase Price multiplied by the number of Common Shares for
which  a Right  is then  exercisable,  in  accordance  with  the  terms  of this
Agreement,  such  number of Common  Shares of the  Principal  Party (as  defined
hereinafter)  including the Company as the successor thereto or as the surviving
corporation,  not subject to any liens, encumbrances,  rights of call, rights of
first refusal or other adverse claims,  as shall be equal to the result obtained
by (A)  multiplying  the then  current  Purchase  Price by the  number of Common
Shares  for  which a Right is then  exercisable  immediately  prior to the first
occurrence of a Section 13 Event (or, if a Section  11(a)(ii) Event has occurred
prior to the first  occurrence of a Section 13 Event,  multiplying  the Purchase
Price in  effect  immediately  prior to the  first  occurrence  of such  Section
11(a)(ii)  Event by the  number  of such  Common  Shares  for  which a Right was
exercisable  immediately  prior to the first  occurrence of a Section  11(a)(ii)
Event) and dividing that product by (B) 50% of the then current per share market
price of the Common  Shares of such  Principal  Party  (determined  pursuant  to
Section 11(d) hereof) on the date of consummation of such consolidation, merger,
sale or transfer;  (ii) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such consolidation, merger, sale or transfer, all the
obligations and duties of the Company pursuant to this Agreement; (iii) the term
"Company" shall  thereafter be deemed to refer to such Principal Party; and (iv)
such Principal Party shall take such steps  (including,  but not limited to, the
reservation  of a  sufficient  number of its Common  Shares in  accordance  with
Section 9 hereof) in connection  with such  consummation  as may be necessary to
assure that the provisions hereof shall thereafter be applicable, as nearly as

                                     - 33 -

<PAGE>



reasonably may be, in relation to the Common Shares thereafter  deliverable upon
the  exercise of the Rights.  If, for any reason,  the Right cannot be exercised
for the Common Shares of the Principal Party,  then a holder of Rights will have
the right to exchange the Rights for cash from such Principal Party in an amount
equal to the number of shares of such Principal Party's Common Shares the holder
is entitled to purchase  multiplied  by 50% of the then current per share market
price, as described in Section 11(d) hereof. If, for some reason, including, but
not limited to,  instances where the Principal  Party has no Common Shares,  the
foregoing  formulation  cannot be applied to determine  the cash amount to which
the holder of a Right is  entitled,  then the Board of  Directors of the Company
shall  determine  such  amount  reasonably  and with  utmost  good faith to such
holders. Any such determination shall be binding and final. If, in the case of a
transaction  of the kind  described in clause (z) of the first  sentence of this
Section 13(a), the Person or Persons to whom assets or earning power are sold or
otherwise  transferred  are  individuals,  then the preceding  sentences of this
Section  13(a)  shall  be  inapplicable,  and the  Company  shall  require  as a
condition  to such sale or  transfer  that such  Person or  Persons  pay to each
holder of a Right  Certificate,  upon its  surrender  to the Rights Agent and in
exchange therefor (without requiring payment by such holder), cash in the amount
determined  by  multiplying  the then  current  Purchase  Price by the number of
Common Shares for which a Right is then exercisable.
                  (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),  the Person (or the
         Company if it is the successor  thereto or the  surviving  corporation)
         that is the issuer of any

                                     - 34 -

<PAGE>



         securities for or into which Common Shares of the Company are converted
         in such share exchange,  merger or consolidation,  and if no securities
         are so issued,  the Person  that is the other  party to such  merger or
         consolidation; 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;
provided,  however,  that in any such  case,  (1) if the  Common  Shares of such
Person are not at such time and have not been  continuously  over the  preceding
twelve (12) month period  registered  under  Section 12 of the Exchange Act, and
such  Person is a direct or  indirect  Subsidiary  of another  Person the Common
Shares of which are and have been so registered,  "Principal  Party" shall refer
to such other Person;  and (2) in case such Person is a Subsidiary,  directly or
indirectly,  of more than one Person,  the Common Shares of two or more of which
are and have been so registered,  "Principal  Party" shall refer to whichever of
such Persons is the issuer of the Common  Shares  having the greatest  aggregate
market value.
                  (c) The  Company  shall not  consummate  any  Section 13 Event
unless the Principal Party shall have a sufficient  number of authorized  shares
of Common  Shares  which have not been issued or reserved for issuance to permit
the exercise in full of the Rights in accordance with this Section 13 and unless
prior  thereto the  Company and 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

                                     - 35 -

<PAGE>



providing  that,  as soon as  practicable  after the date of any such Section 13
Event, the Principal Party will:
                         (i) prepare and file a registration statement under the
         Securities   Act,  with  respect  to  the  Rights  and  the  securities
         purchasable  upon exercise of the Rights on an  appropriate  form,  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 Final Expiration Date;
                        (ii) use its best  efforts to qualify  or  register  the
         Rights and the securities purchasable upon exercise of the Rights under
         the  securities  or  blue  sky  laws of  such  jurisdictions  as may be
         necessary or appropriate; and
                       (iii) will  deliver  to holders of the Rights  historical
         financial statements for the Principal Party and each of its Affiliates
         which comply in all respects with the  requirements for registration on
         Form 10 under the Exchange Act.
The  provisions of this Section 13 shall  similarly  apply to  successive  share
exchanges,  mergers or consolidations or sales or other transfers.  In the event
that a Section 13 Event shall occur at any time after the first  occurrence of a
Section  11(a)(ii)  Event,  the Rights which have not theretofore been exercised
shall  thereafter  become  exercisable in the manner described in Section 13(a).
The Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such  transaction  there are any rights,  warrants,
instruments or securities  outstanding or any agreements or arrangements  which,
as a result of the

                                     - 36 -

<PAGE>



consummation of such transaction,  would eliminate or substantially diminish the
benefits intended to be afforded by the Rights.
                  Section 14. Fractional Rights and Fractional  Shares.  (a) The
Company  shall not be required  to issue  fractions  of Rights or to  distribute
Right Certificates which evidence  fractional Rights. In lieu of such fractional
Rights,  there shall be paid to the registered holders of the Right Certificates
with regard to which such  fractional  Rights would  otherwise  be issuable,  an
amount in cash equal to the same fraction of the current market value of a whole
Right.  For the purposes of this Section  14(a),  the current  market value of a
whole  Right  shall be the  closing  price of the  Rights  for the  Trading  Day
immediately  prior to the date on which such  fractional  Rights would have been
otherwise issuable.  The closing price for any day shall be the last sale price,
regular  way,  or, in case no such sale takes place on such day,  the average of
the closing bid and asked prices, regular way, in either case as reported in the
principal  consolidated  transaction reporting system with respect to securities
listed or  admitted to trading on the Nasdaq  National  Market or, if the Rights
are not listed or admitted to trading on the Nasdaq National Market, as reported
in the  principal  consolidated  transaction  reporting  system with  respect to
securities  listed on the principal  national  securities  exchange on which the
Rights are  listed or  admitted  to trading  or, if the Rights are not listed or
admitted to trading on any national securities  exchange,  the last quoted price
or,  if not so  quoted,  the  average  of the high bid and low  asked  prices as
reported by such other system then in use or, if on any such date the Rights are
not quoted by any such  organization,  the  average of the closing bid and asked
prices as furnished by a professional market maker making a market in the Rights
selected by the Board of Directors of the Company. If on any

                                     - 37 -

<PAGE>



such date no such market maker is making a market in the Rights,  the fair value
of the Rights on such date as determined in good faith by the Board of Directors
of the Company shall be used.
                  (b) The Company  shall not be required to issue  fractions  of
Common Shares upon exercise of the Rights or to  distribute  certificates  which
evidence  fractional  Common Shares.  In lieu of fractional  Common Shares,  the
Company shall pay to the registered  holders of Right  Certificates  at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of a Common Share. For the purposes of this
Section  14(b),  the current market value of a Common Share shall be the closing
price of a Common  Share (as  determined  pursuant  to the  second  sentence  of
Section  11(d)(i)  hereof) for the Trading Day immediately  prior to the date of
such exercise.
                  (c) The  holder  of a Right  by the  acceptance  of the  Right
expressly  waives his right to receive any  fractional  Rights or any fractional
shares upon exercise of a Right (except as provided above).
                  Section 15. Rights of Action.  All rights of action in respect
of this  Agreement,  excepting  the rights of action  given to the Rights  Agent
under Section 18 hereof, are vested in the respective  registered holders of the
Right  Certificates (and, prior to the Distribution Date, the registered holders
of the Common Shares);  and any registered  holder of any Right Certificate (or,
prior to the  Distribution  Date, of the Common Shares),  without the consent of
the Rights Agent or of the holder of any other Right  Certificate  (or, prior to
the Distribution Date, of the Common Shares), may, in his own behalf and for his
own benefit,

                                     - 38 -

<PAGE>



enforce,  and may institute and maintain any suit, action or proceeding  against
the Company to enforce,  or  otherwise  act in respect of, his right to exercise
the Rights  evidenced by such Right  Certificate in the manner  provided in such
Right  Certificate and in this Agreement.  Without limiting the foregoing or any
remedies  available to the holders of Rights,  it is  specifically  acknowledged
that the  holders  of Rights  would not have an  adequate  remedy at law for any
breach of this  Agreement  and will be entitled to specific  performance  of the
obligations under, and injunctive relief against actual or threatened violations
of the obligations of any Person subject to, this Agreement.
                  Section 16.  Agreement  of Right  Holders.  Every  holder of a
Right,  by  accepting  the same,  consents  and agrees  with the Company and the
Rights Agent and with every other holder of a Right that:
                  (a)      prior to the Distribution Date, the Rights will be 
transferable only in connection with the transfer of the Common Shares;
                  (b) after the  Distribution  Date, the Right  Certificates are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the principal  office of the Rights Agent,  duly  endorsed or  accompanied  by a
proper instrument of transfer;
                  (c) subject to Section 6 and Section 7 (f) hereof, the Company
and the  Rights  Agent  may deem and treat  the  person in whose  name the Right
Certificate  (or prior to the  Distribution  Date, the associated  Common Shares
certificate)  is  registered  as the  absolute  owner  thereof and of the Rights
evidenced thereby  (notwithstanding any notations of ownership or writing on the
Right  Certificates or the associated  Common Shares  certificate made by anyone
other than the Company or the Rights Agent) for all purposes whatsoever,

                                     - 39 -

<PAGE>



and neither the Company nor the Rights Agent, subject to 7(e) hereof, 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. Right Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Right Certificate shall be entitled to vote,  receive
dividends  or be deemed for any purpose  the holder of the Common  Shares or any
other  securities  of the  Company  which  may at any  time be  issuable  on the
exercise of the Rights represented  thereby, nor shall anything contained herein
or in any Right  Certificate be construed to confer upon the holder of any Right
Certificate,  as such,  any of the rights of a stockholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
stockholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
stockholders  (except as provided in Section 25 hereto), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Right  Certificate  shall  have  been  exercised  in  accordance  with the
provisions hereof.

                  Section 18. Concerning the Rights Agent. The Company agrees to
pay to the Rights Agent reasonable  compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent,  its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this  Agreement and the exercise and  performance of its duties
hereunder.  The Company  also agrees to  indemnify  the Rights Agent for, and to
hold it harmless  against,  any loss,  liability,  or expense,  incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection  with the  acceptance
and  administration  of this  Agreement,  including  the costs and  expenses  of
defending  against  any claim of  liability  arising  therefrom.  The  indemnity
provided for herein shall survive the expiration of the Rights,  the termination
of this Agreement, and the resignation or removal of the Rights Agent. The costs
and expenses of enforcing  this right of  indemnification  shall also be paid by
the Company.
                  The  Rights  Agent  may  conclusively  rely  upon and shall be
protected  and shall incur no liability  for, or in respect of any action taken,
suffered  or  omitted  by it in  connection  with,  its  administration  of this
Agreement in reliance upon any Right  Certificate or certificate  for the Common
Shares or Common Shares or for other  securities  of the Company,  instrument of
assignment  or transfer,  power of  attorney,  endorsement,  affidavit,  letter,
notice, direction, consent,  certificate,  statement, or other paper or document
believed by it to be genuine and to be signed,  executed and,  where  necessary,
verified or acknowledged, by the proper person or persons, or otherwise upon the
advice of counsel as set forth in Section 20 hereof.

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

                  In case at any  time  the name of the  Rights  Agent  shall be
changed  and at  such  time  any of  the  Right  Certificates  shall  have  been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right  Certificates  so  countersigned;  and in
case  at  that  time  any  of  the  Right   Certificates  shall  not  have  been
countersigned,  the Rights Agent may countersign such Right Certificates  either
in its prior  name or in its  changed  name;  and in all such  cases  such Right
Certificates shall have the full force provided in the Right Certificates and in
this 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,  and no implied duties or obligations  shall be
read into this Agreement  against the Rights Agent,  by all of which the Company
and the holders of Right  Certificates,  by their acceptance  thereof,  shall be
bound:
                  (a) Before the Rights Agent acts or refrains from acting,  the
Rights  Agent may consult with legal  counsel (who may be legal  counsel for the
Company),   and  the  opinion  of  such  counsel  shall  be  full  and  complete
authorization  and  protection  to the Rights  Agent as to any  action  taken or
omitted by it in good faith and in accordance with such opinion.
                  (b)  Whenever  in the  performance  of its  duties  under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or  established by the Company prior to taking or suffering any
action hereunder,  such fact or matter (unless other evidence in respect thereof
be herein  specifically  prescribed) may be deemed to be conclusively proved and
established  by a certificate  signed by any one of the Chairman of the Board of
Directors, the Chief Executive Officer, the President, any vice

                                     - 43 -

<PAGE>



President,  the  Treasurer or the  Secretary of the Company and delivered to the
Rights Agent;  and such  certificate  shall be full  authorization to the Rights
Agent for any action taken or suffered in good faith by it under the  provisions
of this Agreement in reliance upon such certificate.
                  (c) The Rights Agent shall be liable  hereunder to the Company
and any  other  Person  only  for its  own  negligence,  bad  faith  or  willful
misconduct.
                  (d) The Rights  Agent  shall not be liable for or by reason of
any of the statements of fact or recitals  contained in this Agreement or in the
Right  Certificates  (except  its  countersignature  thereof)  or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.
                  (e) The Rights Agent shall not be under any  responsibility in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or  execution  of any Right  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Right  Certificate;
nor shall it be responsible for any change in the  exercisability  of the Rights
(including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or any
adjustment in the terms of the Rights  (including  the manner,  method or amount
thereof) provided for in Section 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right  Certificates  after actual
notice  that such change or  adjustment  is  required);  nor shall it by any act
hereunder be deemed to make any representation or warranty as to the

                                     - 44 -

<PAGE>



authorization  or reservation of any Common Shares to be issued pursuant to this
Agreement or any Right Certificate or as to whether any Common Shares will, when
issued, be validly authorized and issued, fully paid and nonassessable.
                  (f)  The  Company  agrees  that  it  will  perform,   execute,
acknowledge  and deliver or cause to be performed,  executed,  acknowledged  and
delivered  all such further and other acts,  instruments  and  assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.
                  (g) The Rights  Agent is hereby  authorized  and  directed  to
accept instructions with respect to the performance of its duties hereunder from
any one of the Chairman of the Board of Directors,  the Chief Executive Officer,
the  President,  any Vice  President,  the  Secretary  or the  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 by
it in good faith in accordance with  instructions of any such officer or for any
delay in acting while waiting for those instructions.
                           Any application by the Rights Agent for written
instructions  from the Company may, at the option of the Rights Agent, set forth
in writing any action  proposed to be taken or omitted by the Rights Agent under
this Rights  Agreement and the date on or after which such action shall be taken
or such omission  shall be  effective.  The Rights Agent shall not be liable for
any action  taken by, or  omission  of, the Rights  Agent in  accordance  with a
proposal included in any such application on or after the date specified in such
application  (which date shall not be less than ten Business Days after the date
any officer of the Company actually receives such  application,  unless any such
officer shall have consented in writing to

                                     - 45 -

<PAGE>



an earlier date) unless,  prior to taking any such action (or the effective date
in the case of an  omission),  the  Rights  Agent  shall have  received  written
instructions in response to such  application  subject to the proposed action or
omission and/or specifying the action to be taken or omitted.
                  (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the  Company  may be  interested,  or  contract  with or lend money to the
Company or otherwise  act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.
                  (i) The  Rights  Agent may  execute  and  exercise  any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through  its  attorneys  or agents,  and the Rights  Agent shall not be
answerable or  accountable  for any act,  default,  neglect or misconduct of any
such attorneys or agents or for any loss to the Company  resulting from any such
act, default,  neglect or misconduct,  provided reasonable care was exercised in
the selection and continued employment thereof.
                  (j) If, with respect to any Right  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 or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise of transfer without first consulting with the Company.

                  (k) 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.
                  (l) The Rights  Agent  shall not be required to take notice or
be deemed to have notice of any fact, event or determination (including, without
limitation,  any dates or events defined in this Agreement or the designation of
any Person as an Acquiring Person,  Affiliate or Associate) under this Agreement
unless and until the Rights Agent shall be  specifically  notified in writing by
the Company of such fact, event or determination.
                  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 thirty (30) days' notice in writing mailed to the Company and to
each  transfer  agent of the Common  Shares or Common  Shares by  registered  or
certified  mail, at the expense of the Company,  and to the holders of the Right
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor  Rights Agent upon thirty (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 Shares or Common Shares by registered or certified mail, and
to the holders of the Right  Certificates  by  first-class  mail.  If the Rights
Agent shall resign or be removed or shall otherwise  become incapable of acting,
the Company shall appoint a successor to the Rights Agent.  If the Company shall
fail to make such  appointment  within a period of thirty (30) days after giving
notice of such removal or after it has been notified in writing of such

                                     - 47 -

<PAGE>



resignation or incapacity by the resigning or  incapacitated  Rights Agent or by
the holder of a Right Certificate (who shall, with such notice, submit his Right
Certificate  for inspection by the Company),  then the registered  holder of any
Right  Certificate  may apply to any  court of  competent  jurisdiction  for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court,  shall be a  corporation  organized and doing
business  under the laws of the United States or of the State of Illinois (or of
any other state of the United States so long as such  corporation  is authorized
to do  business  as a banking  institution  in the State of  Illinois),  in good
standing,  having an office in the State of Illinois,  which is authorized under
such laws to exercise corporate trust or stock transfer powers and is subject to
supervision or  examination  by federal or state  authority and which has at the
time of its  appointment  as Rights  Agent a combined  capital and surplus of at
least $50 million. After appointment, the successor Rights Agent shall be vested
with the same  powers,  rights,  duties and  responsibilities  as if it had been
originally  named  as  Rights  Agent  without  further  act  or  deed;  but  the
predecessor  Rights  Agent shall  deliver and transfer to the  successor  Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance,  conveyance, act or deed necessary for the purpose. Not later
than the effective  date of any such  appointment  the Company shall file notice
thereof in writing with the predecessor  Rights Agent and each transfer agent of
the Common Shares and mail a notice thereof in writing to the registered holders
of the Right  Certificates.  Failure  to give any  notice  provided  for in this
Section 21,  however,  or any defect  therein,  shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be.

                  Section   22.    Issuance    of   New   Right    Certificates.
Notwithstanding  any of the provisions of this Agreement or of the Rights to the
contrary,  the  Company  may,  at  its  option,  issue  new  Right  Certificates
evidencing  Rights in such 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 Right
Certificates  made in  accordance  with the  provisions  of this  Agreement.  In
addition, in connection with the issuance or sale of Common Shares following the
Distribution  Date and prior to the redemption or expiration of the Rights,  the
Company (a) shall,  with respect to Common Shares so issued or sold (i) pursuant
to the exercise of stock options or under any employee plan or  arrangement,  or
(ii) upon the exercise,  conversion or exchange of securities hereinafter issued
by the  Company,  and (b)  may,  in any  other  case,  if  deemed  necessary  or
appropriate by the Board of Directors of the Company,  issue Right  Certificates
representing  the appropriate  number of Rights in connection with such issuance
or sale; provided,  however,  that (i) no such Right 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 to the Person to whom such Right Certificate would be issued, and
(ii) no such Right  Certificate  shall be issued  if,  and to the  extent  that,
appropriate  adjustments  shall otherwise have been made in lieu of the issuance
thereof.
                  Section  23.  Redemption.  (a) The Board of  Directors  of the
Company may, at its option, at any time prior to such time as any Person becomes
an  Acquiring  Person,  redeem  all but not less  than all the then  outstanding
Rights  at a  redemption  price of $.01 per  Right,  appropriately  adjusted  to
reflect any stock split, stock dividend or similar transaction occurring

                                     - 49 -

<PAGE>



after the date hereof (such  redemption price being  hereinafter  referred to as
the "Redemption Price") provided however,  that if such authorization  occurs on
or after the date of a change (resulting from proxy or consent solicitations) in
a majority of the  directors  in office at the  commencement  of any or all such
solicitations,  and any Person who is or was a participant in such solicitations
has stated (or if upon the commencement of such solicitations, a majority of the
Board of Directors of the Company has determined in good faith) that such Person
(or any of its  Affiliates or  Associates)  has taken or intends to take, or may
consider  taking,  any action  that would  result in such  Person  becoming  any
Acquiring  Person,  or that would cause the  occurrence  of a Section  11(a)(ii)
Event or Section 13 Event (the existence of the circumstances  described in this
proviso  being  referred  herein as an "Adverse  Change of  Control"),  then the
Rights may be so redeemed only if there are  Continuing  Directors in office and
such  redemption  is  authorized  by a majority  of such  Continuing  Directors.
"Continuing Director" shall mean (i) any member of the Board of Directors of the
Company who, while such person is a member of the Board of Directors,  is not an
Acquiring  Person,  or an Affiliate or  Associate of an Acquiring  Person,  or a
representative of an Acquiring Person or of any such Affiliate or Associate, and
was a member of the Board of  Directors  prior to the Record  Date,  or (ii) any
Person who  subsequently  becomes a member of the Board of Directors  who, while
such Person is a member of the Board of Directors,  is not an Acquiring  Person,
or an Affiliate or Associate of an Acquiring  Person,  or a representative of an
Acquiring  Person  or of any  such  Affiliate  or  Associate,  if such  Person's
nomination  for election or election to the Board of Directors is recommended or
approved by a majority of the Continuing Directors. The redemption of the Rights
by the Board of Directors may be

                                     - 50 -

<PAGE>



made effective at such time, on such basis and with such conditions as the Board
of Directors in its sole  discretion  may  establish.  The Company,  may, at its
option, pay the Redemption Price in cash (whether in United States dollars or in
such other  currency or  currencies  as the Board of Directors  may  determine),
Common  Shares  (based  on the  current  market  price  per share at the time of
redemption) or any other form of consideration  deemed  appropriate by the Board
of Directors.
                  (b)  Immediately  upon the action of the Board of Directors of
the Company  ordering the redemption of the Rights  pursuant to paragraph (a) of
this  Section 23, and without  any  further  action and without any notice,  the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the  Redemption  Price.  The Company shall
promptly give public notice of any such redemption;  provided, however, that the
failure to give, or any defect in, any such notice shall not affect the validity
of such  redemption.  Within  ten (10) days  after  such  action of the Board of
Directors ordering the redemption of the Rights, the Company shall mail a notice
of  redemption to all the holders of the then  outstanding  Rights at their last
addresses as they appear upon the  registry  books of the Rights Agent or, prior
to the  Distribution  Date, on the registry  books of the transfer agent for the
Common Shares. Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such notice of
redemption  will state the method by which the payment of the  Redemption  Price
will be made.  Neither the Company nor any of its  Affiliates or Associates  may
redeem, acquire or purchase for value any Rights at any time in any manner other
than

                                     - 51 -

<PAGE>



that  specifically  set forth in this  Section 23 or in  Section 24 hereof,  and
other  than in  connection  with the  purchase  of  Common  Shares  prior to the
Distribution Date.
                  Section  24.  Exchange.  (a) The  Board  of  Directors  of the
Company  may, at its option,  at any time after any Person  becomes an Acquiring
Person,  exchange all or part of the then  outstanding  and  exercisable  Rights
(which shall not include Rights that have become void pursuant to the provisions
of Section 7(e) and Section  11(a)(ii)  hereof) for Common Shares at an exchange
ratio of one Common Share per Right, appropriately adjusted to reflect any stock
split,  stock dividend or similar  transaction  occurring  after the date hereof
(such exchange  ratio being  hereinafter  referred to as the "Exchange  Ratio").
Notwithstanding the foregoing,  the Board of Directors shall not be empowered to
effect such exchange at any time after any Person  (other than the Company,  any
Subsidiary of the Company,  any employee benefit plan of the Company or any such
Subsidiary,  or any entity holding Common Shares for or pursuant to the terms of
any such plan),  together  with all  Affiliates  and  Associates of such Person,
becomes  the  Beneficial  Owner  of  50%  or  more  of the  Common  Shares  then
outstanding.
                  (b)  Immediately  upon the action of the Board of Directors of
the Company  ordering  the exchange of any Rights  pursuant to paragraph  (a) of
this Section 24 and without any further action and without any notice, the right
to exercise  such Rights  shall  terminate  and the only right  thereafter  of a
holder of such Rights shall be to receive that number of Common  Shares equal to
the number of such Rights held by such holder  multiplied by the Exchange Ratio.
The Company shall  promptly give public notice of any such  exchange;  provided,
however,  that the  failure to give,  or any defect in,  such  notice  shall not
affect the

                                     - 52 -

<PAGE>



validity of such exchange.  The Company promptly shall mail a notice of any such
exchange to all of the holders of such  Rights at their last  addresses  as they
appear upon the registry  books of the Rights Agent.  Any notice which is mailed
in the manner herein  provided shall be deemed given,  whether or not the holder
receives the notice. Each such notice of exchange will state the method by which
the exchange of the Common  Shares for Rights will be effected and, in the event
of any  partial  exchange,  the number of Rights  which will be  exchanged.  Any
partial exchange shall be effected pro rata based on the number of Rights (other
than Rights which have become void  pursuant to the  provisions  of Section 7(e)
and Section 11(a)(ii) hereof) held by each holder of Rights.
                  (c) In the event that  there  shall not be  sufficient  Common
Shares  issued but not  outstanding  or  authorized  but  unissued to permit any
exchange  of Rights as  contemplated  in  accordance  with this  Section 24, the
Company  shall take all such action as may be necessary to authorize  additional
Common  Shares for issuance upon exchange of the Rights or shall take such other
action specified in Section 11(a)(iii) hereof.
                  (d) The Company  shall not be required to issue  fractions  of
Common Shares or to distribute  certificates  which evidence  fractional  Common
Shares. In lieu of such fractional  Common Shares,  the Company shall pay to the
registered  holders  of  the  Right  Certificates  with  regard  to  which  such
fractional  Common Shares would otherwise be issuable an amount in cash equal to
the same fraction of the current  market value of a whole Common Share.  For the
purposes of this paragraph (d), the current market value of a whole Common Share
shall be the  closing  price of a Common  Share (as  determined  pursuant to the
second

                                     - 53 -

sentence of Section 11(d) (i) hereof) for the Trading Day  immediately  prior to
the date of exchange pursuant to this Section 24.
         Section 25.  Notice of Certain  Events.  (a) In case the Company  shall
propose (i) to pay any dividend  payable in stock of any class to the holders of
its Common Shares or to make any other distribution to the holders of its Common
Shares  (other than a regular  quarterly  cash  dividend),  (ii) to offer to the
holders of its Common  Shares rights or warrants to subscribe for or to purchase
any  additional  Common  Shares  or  shares  of stock of any  class or any other
securities,  rights or  options,  (iii) to effect  any  reclassification  of its
Common Shares (other than a  reclassification  involving only the subdivision of
outstanding  Common Shares),  (iv) to effect any consolidation or merger into or
with,  or to effect any sale or other  transfer (or to permit one or more of its
Subsidiaries to effect any sale or other transfer), in one or more transactions,
of 50% or  more  of  the  assets  or  earning  power  of  the  Company  and  its
Subsidiaries  (taken as a whole)  to,  any other  Person,  or (v) to effect  the
liquidation,  dissolution or winding up of the Company, then, in each such case,
the Company shall give to each holder of a Right Certificate, in accordance with
Section 26 hereof,  a notice of such  proposed  action,  which shall specify the
record date for the purposes of such stock  dividend,  or distribution of rights
or warrants, or the date on which such reclassification,  consolidation, merger,
sale, transfer, liquidation, dissolution, or winding up is to take place and the
date of participation  therein by the holders of the Common Shares,  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 ten 10 days  prior to the record
date for  determining  holders of the Common Shares for purposes of such action,
and in the case of any such other action, at least ten (10) days

                                     - 54 -

<PAGE>



prior  to the  date  of the  taking  of  such  proposed  action  or the  date of
participation  therein by the holders of the Common Shares,  whichever  shall be
the earlier.
                  (b) In case the event set forth in  Section  11(a)(ii)  hereof
shall occur,  then the Company shall as soon as practicable  thereafter  give to
each holder of a Right  Certificate,  in  accordance  with Section 26 hereof,  a
notice of the  occurrence of such event,  which notice shall describe such event
and the consequences of such event to holders of Rights under Section  11(a)(ii)
hereof.
                  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 on any such action.
                  Section 26.  Notices.  Notices or demands  authorized  by this
Agreement  to be given or made by the Rights Agent or by the holder of any Right
Certificate  to or on the Company shall be sent by registered or certified  mail

                  Section 27.  Supplements and Amendments.  The Company may from
time to time  supplement  or amend this  Agreement  without the  approval of any
holders  of Right  Certificates  in order to cure any  ambiguity,  to correct or
supplement any provision contained herein which may be defective or inconsistent

Sections  1(a) and 3(a) to not less than the greater of (i) the sum of .001% and

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.  For all purposes of this Agreement, any calculation of the number of
Common Shares  outstanding  at any  particular  time,  including for purposes of
determining the particular percentage of such outstanding Common Shares of which
any person is the Beneficial  Owner,  shall be made in accordance  with the last

                  Section  30.  Benefits  of  this  Agreement.  Nothing  in this
Agreement shall be construed to give to any person or corporation other than the
Company,  the Rights Agent and the registered  holders of the Right Certificates

                          SUMMARY OF RIGHTS TO PURCHASE

<PAGE>




                                                                       EXHIBIT B

                          SUMMARY OF RIGHTS TO PURCHASE
                                  COMMON SHARES

                  The  Board of  Directors  of SPSS  Inc.  (the  "Company")  has
declared a dividend of one common  share  purchase  right (a  "Right")  for each
outstanding  share of common  stock,  par  value  $.01 per  share  (the  "Common
Shares"),  of the Company,  payable on June 30, 1998 (the "Record  Date") to the
stockholders of record on that date. Upon the occurrence of certain events, each
Right  entitles the  registered  holder to purchase  from the Company one Common
Share (or in certain  circumstances,  cash, property or other securities) of the
Company at a price of $175 per Common Share (the "Purchase  Price"),  subject to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement  (the  "Rights  Agreement")  between the Company and Harris  Trust and
Savings Bank, as Rights Agent (the "Rights Agent").

                  Initially,   with   respect  to  any  of  the   Common   Share
certificates  outstanding as of the Record Date, the Rights will be evidenced by
a Common  Share  certificate  together  with a copy of this  Summary  of  Rights
attached thereto and no separate Rights  Certificates will be distributed.  With
respect to Common Share  certificates  issued after the Record Date,  the Rights
will be evidenced by a legend affixed to each such certificate incorporating the
Rights Agreement by reference.

                  The Rights  are not  exercisable  and are not freely  tradable
separate from the Common  Shares until the  occurrence  of a  Distribution  Date
("Distribution  Date").  A  Distribution  Date occurs upon the earlier of (i) 10
days  following a public  announcement  that a person or group of  affiliated or
associated  persons  have  acquired  beneficial  ownership of 15% or more of the
outstanding Common Shares ("Acquiring Person") or (ii) 10 business days (or some
later date as the Board of Directors may determine)  following the  commencement
of, or announcement of an intention to make, a tender offer or exchange offer by
a person or group of affiliated or associated persons, the consummation of which
would  result  in the  beneficial  ownership  of 15% or more of the  outstanding
Common Shares or where Continuing Directors deem certain events have constituted
an Adverse Change of Control (as herein more fully described).

                  The Rights  Agreement  provides that,  until the  Distribution
Date (or an earlier  redemption or  expiration  of the Rights),  the Rights will
only be transferred with the Common Shares,  however, the surrender for transfer
of any  certificates  for Common Shares  outstanding as of the Record Date, even
without a legend or a copy of this  Summary of Rights  being  attached  thereto,
will also  constitute  the  transfer  of the Rights  associated  with the Common
Shares  represented  by such  certificate.  As soon as  practicable  following a
Distribution  Date,   separate   certificates   evidencing  the  Rights  ("Right
Certificates")  will be mailed to holders  of record of the Common  Shares as of
the close of business on the Distribution Date and such

                                       B-1

<PAGE>



separate  Right  Certificates  alone will evidence the Rights.  Such Rights are,
however, null and void as to any Acquiring Person.

                  The Rights will expire on June 18, 2008 (the "Final Expiration
Date"),  unless the Final  Expiration  Date is extended or unless the Rights are
earlier redeemed or exchanged by the Company, in each case, as described below.

                  The Purchase Price payable, and the number of Common Shares or
other securities or property issuable,  upon exercise of the Rights, are subject
to customary  adjustments from time to time to prevent dilution (i) in the event
of a stock dividend on, or a subdivision,  combination or  reclassification  of,
the  Common  Shares,  (ii) upon the grant to  holders  of the  Common  Shares of
certain  rights or warrants to  subscribe  for or  purchase  Common  Shares at a
price,  or securities  convertible  into Common Shares with a conversion  price,
less than the  then-current  market price of the Common Shares or (iii) upon the
distribution  to holders of the Common  Shares of evidences of  indebtedness  or
assets  (excluding  regular  periodic  cash  dividends  paid out of  earnings or
retained  earnings or  dividends  payable in Common  Shares) or of  subscription
rights or warrants (other than those referred to above).

                  With certain  exceptions,  no adjustment in the Purchase Price
will be required until cumulative  adjustments amount to an increase or decrease
of at least 1% in such  Purchase  Price.  The  Company  shall not be required to
issue  fractional  Rights or shares and in lieu  thereof,  an adjustment in cash
will be made based on the current market value of the Rights or shares.

                  In the  event  that  any  person  or group  of  affiliated  or
associated  persons becomes an Acquiring Person,  proper provision shall be made
so that each  holder of a Right,  other than  Rights  beneficially  owned by the
Acquiring  Person (which are void),  will  thereafter have the right to receive,
upon  exercise of the Right,  that number of Common Shares having a market value
of two times the exercise price of the Right.

                  In the event that the Company is acquired in a merger or other
business  combination  transaction or 50% or more of its consolidated  assets or
earning  power are sold after a person or group has become an Acquiring  Person,
each  holder of a Right  will  thereafter  have the right to  receive,  upon the
exercise thereof at the then current exercise price of the Right, that number of
shares  of  common  stock  of the  acquiring  company  which at the time of such
transaction  will have a market  value of two times  the  exercise  price of the
Right, or in circumstances such as where the Right cannot be exercised for stock
or the assets of the Company have been  distributed,  an amount of cash equal to
the value of such Rights shall be paid.

                  At any time  after any person or group  becomes  an  Acquiring
Person and prior to the  acquisition  by such  person or group of 50% or more of
the  outstanding  Common  Shares,  the Board of  Directors  of the  Company  may
exchange the Rights (other than Rights

                                       B-2

<PAGE>



owned by such person or group which will have become void), in whole or in part,
at an exchange ratio of one Common Share, per Right (subject to adjustment).

                  At any time prior to the  acquisition  by a person or group of
affiliated or associated  persons of beneficial  ownership of 15% or more of the
outstanding  Common Shares, the Board of Directors of the Company may redeem the
Rights in whole,  but not in part, at a price of $.01 per Right (the "Redemption
Price") provided,  however,  if the authorization to redeem the Rights occurs on
or after the date of a change in a  majority  of the Board of  Directors  of the
Company  as a result of proxy or  consent  solicitations  and a person who was a
participant  in such  solicitations  has stated  that such person (or any of its
affiliates  or  associates)  has taken,  intends to take or may consider  taking
actions  that would  result in such  person  becoming an  Acquiring  Person (the
existence of these circumstances being an "Adverse Change of Control"), then the
redemption  of the  Rights  will  require  the  approval  of a  majority  of the
Continuing Directors. "Continuing Director" means (i) any member of the Board of
Directors of the Company who is not an Acquiring  Person,  (or a representative,
affiliate or associate  of an Acquiring  Person),  and was a member of the Board
prior to the Record Date, or (ii) any person who  subsequently  becomes a member
of the Board who is not an Acquiring Person (or a  representative,  affiliate or
associate of an Acquiring Person),  if such Person's  nomination for election or
election to the Board is recommended or approved by a majority of the Continuing
Directors.

                  The  terms  of the  Rights  may be  amended  by the  Board  of
Directors  of the  Company  without  the  consent of the  holders of the Rights,
including an amendment to lower certain  thresholds  described  above  regarding
percentage  ownership  whereby any person or group of  affiliated  or associated
persons becomes an Acquiring Person,  provided,  however,  no such amendment may
adversely  affect the  interests of the holders of the Rights.  Until a Right is
exercised,  the holder thereof, as such, will have no rights as a stockholder of
the  Company,  including,  without  limitation,  the right to vote or to receive
dividends.

                  A copy  of the  Rights  Agreement  has  been  filed  with  the
Securities and Exchange Commission as an Exhibit to a Registration  Statement on
Form 8-A. A copy of the Rights  Agreement is  available  free of charge from the
Company  at 444 North  Michigan  Avenue,  Chicago,  Illinois  60611,  Attention:
Corporate Secretary.  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 hereby incorporated herein by reference.
