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

     On December 11, 1996, the Board of Directors of Possis  Medical,  Inc. (the
"Company"),  declared  a  dividend  of one  preferred  share  purchase  right (a
"Right") per share for each  outstanding  share of Common Stock,  par value $.40
(the "Common Shares"),  of the Company.  The dividend is payable on December 23,
1996 (the "Record Date") to shareholders of record on that date.

     Each Right entitles the registered  holder to purchase from the Company one
one-hundredth of a share of Series A Junior  Participating  Preferred Stock, par
value $.40 (the  "Preferred  Shares"),  of the Company at a price of $160.00 per
one-hundredth  of  a  Preferred  Share  (the  "Purchase   Price"),   subject  to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement (the "Rights  Agreement"),  dated as of December 12, 1996, between the
Company and Norwest Bank Minnesota,  National Association,  as Rights Agent (the
"Rights Agent").

     Initially,  the Rights will be evidenced by the  certificates  representing
Common  Shares then  outstanding  and no  separate  Right  Certificates  will be
distributed. The Rights will separate from the Common Shares, and a Distribution
Date for the Rights will occur upon the earlier of: (i) the first date of public
announcement  that a Person or group of  affiliated  or  associated  Persons has
become an "Acquiring Person" (i.e., has become,  subject to certain  exceptions,
the beneficial  owner of 15% or more of the  outstanding  Common Shares) (except
pursuant to a Permitted  Offer,  as  hereinafter  defined) and (ii) the 10th day
following the commencement or public  announcement of a tender offer or exchange
offer, the consummation of which would result in a Person or group of affiliated
or associated Persons becoming,  subject to certain  exceptions,  the beneficial
owner of 15% or more of the outstanding Common Shares (or such later date as may
be  determined  by the Board of  Directors  of the Company  prior to a Person or
group of  affiliated or associated  Persons  becoming an Acquiring  Person) (the
earlier of such dates being called the "Distribution Date").

     A  "Permitted  Offer"  is a  tender  offer  or an  exchange  offer  for all
outstanding Common Shares of the Company at a price and on terms determined by a
majority of the Board of  Directors  of the Company who are not  officers of the
Company and who are not  Acquiring  Persons or  affiliates  or  associates of an
Acquiring Person and after receiving advice from one or more investment  banking
firms, to be (a) fair to shareholders (taking into account all factors which the
Board of Directors  deems  relevant) and (b) otherwise in the best  interests of
the Company and its shareholders employees,  customers,  suppliers and creditors
and the  communities in which the Company does business,  and which the Board of
Directors determines to recommend to the shareholders of the Company.

     Until the Distribution Date, (i) the Rights will be evidenced by the Common
Share certificates and will be transferred with and only with the Common Shares,
(ii) new Common Share certificates issued after the Record Date upon transfer or
new  issuance of the Common  Shares will  contain a notation  incorporating  the
Rights  Agreement  by  reference,  and (iii) the  surrender  for transfer of any
Common Share certificate, even without such notation or a copy of the Summary of
Rights  attached  thereto,  will also  constitute  the  transfer  of the  Rights
associated with the Common Shares represented by such certificate.

     As  promptly as  practicable  following  the  Distribution  Date,  separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution  Date, and such separate Right Certificates alone will evidence the
Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on December 23, 2006, unless extended or earlier redeemed or exchanged by
the Company as described below.

     The  Purchase  Price  payable and the number of  Preferred  Shares or other
securities  or  property  issuable  upon  exercise  of the Rights are subject to
adjustment  from time to time to prevent  dilution:  (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares,  (ii) upon the  grant to  holders  of the  Preferred  Shares of  certain
rights,  options or warrants to subscribe  for or purchase  Preferred  Shares or
convertible  securities  at less  than  the  then  current  market  price of the
Preferred  Shares,  or (iii) upon the  distribution  to holders of the Preferred
Shares of evidences of indebtedness or assets  (excluding  regular periodic cash
dividends or dividends payable in Preferred Shares) or of subscription rights or
warrants  (other than those  described in clause (ii) of this  paragraph).  With
certain  exceptions,  no adjustment in the Purchase Price will be required until
cumulative  adjustments  require an  adjustment  of at least 1% in the  Purchase
Price.
<PAGE>
     No  fraction  of a  Preferred  Share  (other  than  fractions  in  integral
multiples of one  one-hundredth of a share) will be issued and, in lieu thereof,
an  adjustment  in cash  will be made  based  on the  closing  price on the last
trading date prior to the date of exercise.

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

     Preferred  Shares  purchasable  upon  exercise  of the  Rights  will not be
redeemable.  Each  Preferred  Share will be entitled  to a minimum  preferential
quarterly  dividend  payment  of $.01  per  share  but  will be  entitled  to an
aggregate  dividend of 100 times the dividend  declared per Common Share. In the
event of liquidation,  the holders of the Preferred Shares will be entitled to a
minimum preferential  liquidation payment of $.01 per share but will be entitled
to an  aggregate  payment of 100 times the payment made per Common  Share.  Each
Preferred  Share will have 100 votes,  voting  together with the Common  Shares.
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged,  each  Preferred  Share will be entitled to receive
100 times the amount  received  per Common  Share.  These  rights are subject to
adjustment  in  the  event  of a  stock  dividend  on  the  Common  Shares  or a
subdivision, combination or consolidation of the Common Shares.

     In the event that a person or group  becomes an  Acquiring  Person  (except
pursuant to a Permitted Offer (as defined below)), each holder of a Right, other
than the Acquiring Person or the affiliates,  associates or transferees  thereof
(whose  Rights  will  thereafter  be void),  will  thereafter  have the right to
receive upon exercise  thereof at the then current  exercise  price of the Right
that number of Common  Shares  having a market  value of two times the  exercise
price of the Right, subject to certain possible adjustments.

     In the event that the  Company  is  acquired  in  certain  mergers or other
business combination  transactions or 50% or more of the assets or earning power
of the Company and its  subsidiaries  (taken as a whole) are sold after a person
or group becomes an Acquiring  Person  (except  pursuant to a Permitted  Offer),
holders of the Rights will thereafter  have the Right to receive,  upon exercise
thereof at the then current  exercise price of the Right,  that number of Common
Shares of the acquiring  company (or, in certain cases,  one of its  Affiliates)
having a market value of two times the exercise price of the Right.

     At any time after a Person becomes an Acquiring  Person (subject to certain
exceptions),  and  prior to the  acquisition  by a Person  of 50% or more of the
outstanding Common Shares, the Continuing  Directors may exchange all or part of
the Rights for Common Shares at an exchange  ratio per Right equal to the result
obtained  by  dividing  the  exercise  price of a Right by the current per share
market price of the Common Shares, subject to adjustment.

     At any time before a Person has become an Acquiring Person,  the Continuing
Directors  may redeem the Rights in whole,  but not in part,  at a price of $.01
per Right (the "Redemption Price"), subject to adjustment. The redemption of the
Rights  may be made  effective  at  such  time,  on such  basis  and  with  such
conditions  as  such  Continuing   Directors  may,  in  their  sole  discretion,
establish.

     A  "Continuing  Director" is a member of the Board of  Directors  who was a
member of the Board on December 23, 1996, or who subsequently  became or becomes
a member of the Board of  Directors  with the  recommendation  or  approval of a
majority of the Continuing  Directors.  Continuing  Directors do not include any
Acquiring Person or affiliate or associate of an Acquiring Person.
<PAGE>
     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a shareholder of the Company,  including without limitation, the right
to vote or to receive dividends.

     This summary  description of the Rights does not purport to be complete and
is qualified in its  entirety by  reference to the Rights  Agreement,  a copy of
which is filed as an Exhibit hereto and is incorporated herein by reference.

                                RIGHTS AGREEMENT



     AGREEMENT,  dated as of December 12, 1996, between Possis Medical,  Inc., a
Minnesota  corporation  (the  "Company"),  and Norwest Bank Minnesota,  National
Association (the "Rights Agent").

     The Board of  Directors  of the  Company  has  authorized  and  declared  a
dividend of one preferred share purchase right (a "Right") for each Common Share
of the Company  outstanding  at the Close of Business on December  23, 1996 (the
"Record Date"),  each Right representing the right to purchase one one-hundredth
of a Preferred  Share,  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);  provided,
however,  that  Rights may be issued  with  respect to Common  Shares that shall
become  outstanding  after the Distribution Date and prior to the earlier of the
Redemption Date and the Final  Expiration Date in accordance with the provisions
of Section 22 of this Agreement.

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

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

     "Acquiring  Person"  shall mean any Person who or which,  together with all
Affiliates and Associates of such Person,  shall be the Beneficial  Owner of the
Threshold  Percentage or more of the Common Shares then outstanding,  other than
pursuant  to a  Permitted  Offer,  but  shall not  include  any  Exempt  Person.
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 the  Threshold  Percentage  or more of the
Common  Shares of the Company then  outstanding;  provided,  however,  that if a
Person shall become the Beneficial Owner of the Threshold  Percentage 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,  increase
the number of Common  Shares of the  Company  beneficially  owned by such Person
above the  number of Common  Shares of the  Company  beneficially  owned by such
Person at the time of the last such share  purchase  by 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 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  then such Person shall
not be deemed to be an "Acquiring Person" for any purposes of this Agreement.

     "Affiliate" and "Associate" shall have the respective  meanings ascribed to
such terms in Rule 12b-2 of the General Rules and Regulations under the Exchange
Act.

     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,   including  without  limitation
securities with respect to which such Person or any such Person's  Affiliates or
Associates  has  "beneficial  ownership"  pursuant to  Rule-13d-3 of the General
Rules and  Regulations  under the Exchange Act, as in effect on the date of this
Agreement;
<PAGE>
     (ii) which such Person or any of such Person's Affiliates or Associates 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 (or any Affiliate or Associate  thereof) with which such Person or any of
such  Person's  Affiliates  or  Associates  has any  agreement,  arrangement  or
understanding (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  clause(ii)(B)  above) 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

     Section 3. Issue of Right Certificates.

     (a) Until the earlier of (i) the Shares  Acquisition Date or (ii) the tenth
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) after the date of
the commencement by any Person (other than an Exempt Person) of, or of the first

to commence,  a tender or exchange offer the  consummation of which would result
in any Person  becoming an  Acquiring  Person  (the  earlier of such dates being
referred to herein as the "Distribution Date"), (y) the Rights will be evidenced
(subject  to the  provisions  of Section  3(b)) 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 (z) 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) by first-class,  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 B (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.

     (b) As soon as  practicable  after the Record Date, the Company will send a
copy of a Summary of Rights to Purchase  Preferred  Shares, in substantially the
form of Exhibit C (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 Close of
Business on 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.  Until the Distribution  Date (or
the earlier of the  Redemption  Date or the Final  Expiration  Date if occurring
prior to the  Distribution  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)  Certificates  for Common  Shares  which become  outstanding  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  Possis  Medical,  Inc.  and
Norwest Bank Minnesota, National Association, dated as of December 12, 1996 (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
Possis  Medical,  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.  Possis Medical,  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  or  an  Associate  or  Affiliate  thereof  (as  defined  in  the  Rights
Agreement), or certain transferees of such Person, 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.
<PAGE>
     Section 4. Form of Right Certificates.

     (a) The Right Certificates (and the forms of election to purchase Preferred
Shares  and of  assignment  to be  printed  on the  reverse  thereof)  shall  be
substantially the same as Exhibit B and may have such marks of identification or
designation and such legends,  summaries or endorsements  printed thereon as the
Company may deem appropriate and as are not inconsistent  with the provisions of
this Agreement,  or as may be required to comply with any applicable law or with
any rule or regulation  made pursuant  thereto or with any rule or regulation of
any stock exchange or automated  quotations  system on which the Rights may from
time to time be listed,  or to conform to usage.  Subject to the  provisions  of
Section 11, the Right Certificates shall entitle the holders thereof to purchase
such number of one  one-hundredths  of a  Preferred  Share as shall be set forth
therein  at the  price  per one  one-hundredth  of a  Preferred  Share set forth
therein (the "Purchase  Price"),  but the number of such one one-hundredths of a
Preferred  Share and the  Purchase  Price  shall be  subject  to  adjustment  as
provided herein.

     (b) Any Rights  Certificate  issued  pursuant to Section 3(a) or Section 22
hereof that represents Rights  beneficially owned by: (i) an Acquiring Person or
any  Associate  or Affiliate of an  Acquiring  Person,  (ii) a transferee  of an
Acquiring  Person  (or of  any  such  Associate  or  Affiliate)  who  becomes  a
transferee  after the Acquiring Person becomes such, or (iii) a transferee of an
Acquiring  Person  (or of  any  such  Associate  or  Affiliate)  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 to holders of equity interests in such
Acquiring  Person  or to any  Person  with whom such  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (B) a  transfer  which  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 Section 7(e) hereof,  and any Rights
Certificate  issued  pursuant to Section 6 or Section 11 hereof  upon  transfer,
exchange,  replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain (to the extent feasible) the following legend:

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

     Section 5. Countersignature and Registration.  The Right Certificates shall
be  executed  on  behalf  of the  Company  by its  Chairman  of the  Board,  its
President,  any of its Vice  Presidents or its Treasurer  either  manually or by
facsimile  signature  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 for purposes of
authorization only 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 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.
<PAGE>
     (a) Subject to the provisions of Section 4(b), Section 7(e) and Section 14,
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  may be
transferred,  split up,  combined or exchanged for another Right  Certificate or
Right Certificates, entitling the registered holder to purchase a like number of
one  one-hundredths  of a Preferred  Share (or,  following a  Triggering  Event,
Common Shares,  other  securities,  cash or other 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.  Thereupon  the Rights
Agent shall, subject to Section 4(b),  Section 7(e),  Section 14 and Section 24,
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 issue, execute and deliver
a new Right  Certificate of like tenor to the Rights Agent for  countersignature
and 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) Subject to Section 7(e), 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  office or offices of the
Rights Agent designated for such purpose,  together with payment of the Purchase
Price for each one one-hundredth of a Preferred Share as to which the Rights are
exercised,  at or prior to the earliest of (i) the Close of Business on December
23, 2006 (the "Final  Expiration  Date"),  (ii) the time at which the Rights are
redeemed as provided in Section 23 (the "Redemption  Date") or (iii) the time at
which such Rights are exchanged as provided in Section 24 (the "Exchange Date").

     (b) The  Purchase  Price for each one  one-hundredth  of a Preferred  Share
purchasable  pursuant to the  exercise of a Right  shall  initially  be $160.00,
shall be subject to adjustment  from time to time as provided in Sections 11 and
13 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 Preferred Shares (or other shares,  securities,  cash
or other assets,  as the case may be) 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 by certified check,  cashier's check or
money  order  payable  to the  order of the  Company,  the  Rights  Agent  shall
thereupon promptly (i) (A) requisition from any transfer agent for the Preferred
Shares (or make  available,  if the Rights Agent is the transfer  agent for such
shares)  certificates for the number of Preferred Shares to be purchased and the
Company hereby irrevocably authorizes its transfer agent to comply with all such
requests,  or (B) if the Company shall have elected to deposit with a depository
agent the total number of Preferred  Shares issuable upon exercise of the Rights
hereunder,   requisition   from  the  depositary   agent   depositary   receipts
representing such number of one one-hundredths of a Preferred Share as are to be
purchased (in which case  certificates for the Preferred  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, (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 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.
<PAGE>
     (d) In case the registered  holder of any Right  Certificate shall exercise
less  than  all  of  the  Rights  evidenced  thereby,  a new  Right  Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the  registered  holder of such Right  Certificate  or to
such holder's duly authorized assigns, subject to the provisions of Section 14.

     (e)  Notwithstanding  anything in this Agreement to the contrary,  from and
after the first occurrence of a Section 11(a)(ii) Event, any Rights Beneficially
Owned by (i) an  Acquiring  Person or an  Associate or Affiliate of an Acquiring
Person,  (ii) a transferee of an Acquiring  Person (or of any such  Associate or
Affiliate) who becomes a transferee  after the Acquiring Person becomes such, or
(iii)  a  transferee  of an  Acquiring  Person  (or of  any  such  Associate  or
Affiliate) 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 to  holders of
equity  interests  in such  Acquiring  Person  or to any  Person  with  whom the
Acquiring  Person has any continuing  agreement,  arrangement  or  understanding
regarding the transferred  Rights or (B) a transfer which 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  become 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.  The Company shall use all
reasonable  efforts  to insure  that the  provisions  of this  Section  7(e) and
Section 4(b) hereof are complied with, but shall have no liability to any holder
of Rights  Certificates  or other  Person as a result of its failure to make any
determinations  with respect to an Acquiring  Person or any of their  respective
Affiliates, Associates or transferees hereunder.

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

     Section 8.  Cancellation and Destruction of Right  Certificates.  All Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for  cancellation or in canceled form,
or, if  surrendered  to the Rights Agent,  shall be canceled by it, and no Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Rights Agreement. The Company shall deliver to the
Rights  Agent for  cancellation  and  retirement,  and the Rights Agent shall so
cancel and retire,  any other  Right  Certificate  purchased  or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all canceled Right Certificates to the Company, or shall, at the written request
of the  Company  and after  any  required  Securities  and  Exchange  Commission
retention  period,  destroy such canceled Right  Certificates,  and in such case
shall deliver a certificate of destruction thereof to the Company.

     Section 9. Availability of Preferred Shares.

     (a) The Company  covenants and agrees that it will cause to be reserved and
kept available out of its authorized and unissued Preferred Shares the number of
Preferred  Shares that will be  sufficient to permit the exercise in full of all
outstanding Rights.

     (b) At such  time,  if any,  as the  Preferred  Shares  issuable  upon  the
exercise  of Rights  may be  listed on any  national  securities  exchange,  the
Company  shall use its best  efforts  to cause,  from and after such time as the
Rights become  exercisable (but only to the extent that it is reasonably  likely
that the Rights will be exercised),  all shares reserved for such issuance to be
listed on such exchange upon official notice of issuance upon such exercise.
<PAGE>
     (c) The Company will  prepare and file,  as soon as  practicable  after the
Distribution Date, a registration statement under the Securities Act of 1933, as
amended (the "Act"),  with respect to the Rights and the securities  purchasable
upon exercise of the Rights on an appropriate  form, and use its best efforts to
cause such registration statement to (i) become effective as soon as practicable
after such filing,  and  (ii) remain  effective  (with a prospectus at all times
meeting the  requirements  of the 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 in connection with the  exercisability of the Rights. The Company
may  temporarily  suspend,  for a period of time not to exceed 90 days after the
date the registration  statement is filed, the  exercisability  of the Rights in
order to permit the registration  statement 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 is not
permitted under applicable law.

     (d) The Company  covenants  and agrees that it will take all such action as
may be necessary to ensure that all Preferred  Shares delivered upon exercise of
Rights shall,  at the time of delivery of the  certificates  for such  Preferred
Shares  (subject to payment of the Purchase  Price and any  applicable  transfer
taxes),  be  duly  and  validly   authorized  and  issued  and  fully  paid  and
nonassessable shares.

     (e) The Company further  covenants and agrees that it will pay when due and
payable any and all federal and state  transfer  taxes and charges  which may be
payable in respect of the issuance or delivery of the Right  Certificates  or of
any  Preferred  Shares  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,  scrip or  depositary  receipts  for the
Preferred Shares 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, scrip or depositary receipts for Preferred Shares upon
the exercise of any Rights until any such tax shall have been paid (any such tax
being payable by the holder of such Right  Certificate at the time of surrender)
or until it has been established to the Company's  reasonable  satisfaction that
no such tax is due.

     Section 10.  Preferred  Shares  Record Date.  Each Person in whose name any
certificate for a number of one  one-hundredths  of a Preferred Share (or Common
Shares and/or other securities,  as the case may be) is issued upon the exercise
of Rights  shall for all  purposes be deemed to have become the holder of record
of the Preferred Shares (or Common Shares and/or other  securities,  as the case
may be) 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  transfer  books of the Company for the  Preferred  Shares 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
such  transfer  books are open.  Prior to the  exercise of the Rights  evidenced
thereby,  the holder of a Right  Certificate shall not be entitled to any rights
of a holder of  Preferred  Shares  for which the  Rights  shall be  exercisable,
including,  without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.
<PAGE>
     Section 11.  Adjustment  of Purchase  Price,  Number of Shares or Number of
Rights.  The Purchase Price, the number and kind of shares covered by each Right
and the number of Rights outstanding are subject to adjustment from time to time
as provided in this Section 11:

     (a)(i) In the event the  Company  shall at any time  after the date of this
Agreement  (A) declare a dividend on the Preferred  Shares  payable in Preferred
Shares,  (B)  subdivide  the  outstanding  Preferred  Shares,  (C)  combine  the
outstanding  Preferred  Shares into a smaller number of Preferred  Shares or (D)
issue any shares of its capital  stock in a  reclassification  of the  Preferred
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 Preferred  Shares 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 which would require an adjustment under both Section 11(a)(i)
and Section  11(a)(ii),  the  adjustment  provided for in this Section  11(a)(i)
shall be in  addition  to, and shall be made prior to, any  adjustment  required
pursuant to Section 11(a)(ii).

     (ii)  Subject  to  Section  24 of this  Agreement,  in the event any Person
becomes an Acquiring Person, other than pursuant to any transaction set forth in
Section  13(a),  then  proper  provision  shall be made so that each holder of a
Right (except as otherwise  provided below and in Section 7(e)) shall thereafter
have a right to receive,  upon  exercise  thereof at the then  current  Purchase
Price in  accordance  with the terms of this  Agreement and in lieu of Preferred
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 one
one-hundredths   of  a  Preferred  Share  for  which  a  Right  was  exercisable
immediately  prior to the  first  occurrence  of a Section  11(a)(ii)  Event 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)) on the date
of the  occurrence of such event (such number of shares being referred to as 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.

     (iii) In the event that the number of Common Shares which are authorized by
the Company's  Articles of  Incorporation  but not  outstanding  or reserved for
issuance for purposes  other than upon exercise of the Rights are not sufficient
to permit the exercise in full of the Rights in  accordance  with the  foregoing
subparagraph  (ii) of this Section  11(a),  the Company  shall (A) determine the
value of the  Adjustment  Shares  issuable  upon the  exercise  of a Right  (the
"Current  Value"),  and (B) with respect to each Right (subject to Section 7(e)
hereof),  make adequate provision to substitute for the Adjustment Shares,  upon
the exercise of a Right and payment of the applicable  Purchase Price, (1) cash,
(2) a  reduction  in the  Purchase  Price,  (3)  Common  Shares or other  equity
securities of the Company (including,  without limitations,  shares, or units of
shares,  of preferred stock,  such as the Preferred  Stock,  which the Board has
deemed to have  essentially  the same value or economic  rights as Common Shares
(such  shares  of   preferred   stock  being   referred  to  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  (less the amount of any  reduction  in the  Purchase  Price),  where such
aggregate  value has been  determined  by the Board  based  upon the advice of a
nationally recognized  investment banking firm selected by the Board;  provided,
however,  that if the Company shall not have made adequate  provision to deliver
value  pursuant to clause (B) above within thirty (30) days  following the first
occurrence of a Section  11(a)(ii) Event, 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. For purposes of the preceding sentence, the term "Spread" shall mean
the excess of (i) the  Current Value over (ii) the Purchase  Price. If the Board
determines in good faith that it is likely that sufficient  additional shares of
Common  Stock could be  authorized  for  issuance  upon  exercise in full of the
Rights, the thirty (30) day period set forth above may be extended to the extent
<PAGE>

necessary, but not more than ninety (90) days after the Section 11(a)(ii) Event,
in order that the Company may seek shareholder approval for the authorization of
such additional shares (such thirty (30) day period,  as it may be extended,  is
herein  called the  "Substitution  Period").  To the extent that action is to be
taken pursuant to the first and/or third  sentences of this Section  11(a)(iii),
the Company (1) shall provide,  subject to Section 7(e) hereof, that such action
shall  apply  uniformly  to all  outstanding  Rights,  and (2) may  suspend  the
exercisability of the Rights until the expiration of the Substitution  Period in
order to seek such  shareholder  approval for such  authorization  of additional
shares and/or to decide the appropriate form of distribution to be made pursuant
to such first sentence and to determine the value  thereof.  In the event of any
such suspension,  the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect. For purposes
of this  Section  11(a)(iii),  the value of each  Adjustment  Share shall be the
"current per share market price" (as  determined  pursuant to Section  11(d)(i))
per Common Share on the date of the first occurrence of Section  11(a)(ii) Event
and the per share or per unit  value of any  Common  Stock  Equivalent  shall be
deemed to equal the "current market price" per Common Share on such date.

     (b) In case the Company shall fix a record date for the issuance of rights,
options  or  warrants  to all  holders of  Preferred  Shares  entitling  them to
subscribe  for or purchase  Preferred  Shares (or shares having the same rights,
privileges  and  preferences  as the  Preferred  Shares  (such shares are herein
called "preferred share  equivalents") or securities  convertible into Preferred
Shares  or  preferred  share  equivalents  at a price  per  Preferred  Share  or
preferred  share  equivalent  (or  having a  conversion  price per  share,  if a
security  convertible into Preferred Shares or preferred share equivalents) less
than the then current per share market price (as such term is defined in Section
11(d)) of the Preferred  Shares 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 Preferred  Shares  outstanding on such
record date plus the number of  Preferred  Shares which the  aggregate  offering
price of the total number of Preferred Shares and/or preferred share equivalents
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  Preferred  Shares
outstanding on such record date plus the number of additional  Preferred  Shares
and/or  preferred share  equivalents 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
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose
determination  shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights  Agent and the holders of the  Rights.  Preferred
Shares held for the account of the Company shall not be deemed  outstanding  for
the purpose of any such computation.  Such adjustment shall be made successively
whenever such a record date is fixed; and in the event that such rights, options
or warrants are not so issued,  the  Purchase  Price shall be adjusted to be the
Purchase  Price  which  would then be in effect if such record date had not been
fixed.

     (c) In case the  Company  shall  fix a  record  date  for the  making  of a
distribution  to all  holders  of  the  Preferred  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 cash dividend or a dividend payable in
Preferred Shares) or subscription  rights or warrants  (excluding those referred
to in Section 11(b)),  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 Preferred 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 Preferred  Share,  and the  denominator of which shall be such
current per share market price of the Preferred 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.
<PAGE>
     (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 30  consecutive  Trading Days
immediately prior to such date;  provided,  however,  that in the event that the
current per share  market price of the  Security is  determined  during a period
following the  announcement  by the issuer of such Security of (A) a dividend or
distribution  on such Security  payable in shares of such Security or securities
convertible  into  such  shares,   or  (B)  any   subdivision,   combination  or
reclassification of such Security and prior to the expiration of 30 Trading Days
after the ex-dividend date for such dividend or distribution, or the record date
for such subdivision,  combination or  reclassification,  then, and in each such
case,  the current per share  market  price shall be  appropriately  adjusted to
reflect the current  market price per share  equivalent  of such  Security.  The
closing  price for each day shall be the last sale price,  regular  way,  or, in
case no such sale takes  place on such day,  the  average of the closing bid and
asked  prices,  regular  way,  in  either  case  as  reported  in the  principal
consolidated  transaction  reporting system with respect to securities listed or
admitted to trading on the New York Stock  Exchange  or, if the  Security is not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal  consolidated  transaction reporting system with respect to securities
listed on the principal  national  securities  exchange on which the Security is
listed or admitted  to trading or, if the  Security is not listed or admitted to
trading on any national securities exchange, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market,  as reported by the National  Association  of Securities  Dealers,  Inc.
Automated  Quotations System ("NASDAQ") or such other system then in use, or, if
on any such  date the  Security  is not  quoted  by any such  organization,  the
average of the  closing  bid and asked  prices as  furnished  by a  professional
market maker making a market in the Security  selected by the Board of Directors
of the  Company.  If on any such day no  market  maker is making a market in the
Common  Shares,  the fair value of such share on such day as  determined in good
faith by the  Board of  Directors  of the  Company  shall be used in lieu of the
closing price for such day. 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 Preferred Shares shall be determined in accordance with the
method set forth in Section 11(d)(i); provided, however, if the Preferred Shares
are not publicly  traded,  the "current per share market price" of the Preferred
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),  multiplied  by one hundred.  If neither the
Common Shares nor the Preferred Shares are publicly held or so listed or traded,
"current per share  market  price" of the  Preferred  Shares 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  one-millionth  of a
Preferred Share or one ten-thousandth 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.
<PAGE>
     (f) If as a result of an  adjustment  made  pursuant  to Section  11(a) and
13(a),  the holder of any Right  thereafter  exercised  shall become entitled to
receive any shares of capital stock of the Company other than Preferred  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
Preferred  Shares  contained in Section  11(a) through (c),  inclusive,  and the
provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred  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 one one-hundredths of a
Preferred  Share  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) below,  subject to the  provisions of Sections  11(a) and 13, upon
each  adjustment of the Purchase Price as a result of the  calculations  made in
Sections 11(b) and (c), each Right  outstanding  immediately prior to the making
of such  adjustment  shall  thereafter  evidence the right to  purchase,  at the
adjusted Purchase Price, that number of one  one-hundredths of a Preferred Share
(calculated to the nearest one  one-millionth  of a Preferred Share) obtained by
(i)  multiplying  (x) the number of one  one-hundredths  of a share 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 one  one-hundredths of a Preferred Share purchasable
upon  the  exercise  of a  Right.  Each of the  Rights  outstanding  after  such
adjustment  of the number of Rights shall be  exercisable  for the number of one
one-hundredths   of  a  Preferred  Share  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 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, 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,  may bear, at the option of
the Company,  the adjusted  Purchase Price, and shall be registered in the names
of the holders of record of Right  Certificates  on the record date specified in
the public announcement.
<PAGE>
     (j)  Irrespective  of any adjustment or change in the Purchase Price or the
number of one  one-hundredths of a Preferred Share issuable upon the exercise of
the  Rights,  the Right  Certificates  theretofore  and  thereafter  issued  may
continue to express the Purchase Price and the number of one one-hundredths of a
Preferred  Share 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 one  one-hundredth  of the then par value,  if any, of the
Preferred  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 Preferred Shares at such adjusted Purchase Price.

     (l) In any case in which this Section 11 shall  require that an  adjustment
in the  Purchase  Price be made  effective  as of a record  date for a specified
event,  the Company may elect to defer  until the  occurrence  of such event the
issuing  to the holder of any Right  exercised  after  such  record  date of the
Preferred  Shares and other capital stock or securities of the Company,  if any,
issuable  upon  such  exercise  over and above the  Preferred  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 in their sole  discretion  the Board of Directors of the Company
shall  determine  to be  advisable  in  order  that  any  (i)  consolidation  or
subdivision  of the  Preferred  Shares,  (ii)  issuance  wholly  for cash of any
Preferred  Shares at less than the current market price,  (iii) issuance  wholly
for cash of Preferred  Shares or securities which by their terms are convertible
into or exchangeable  for Preferred  Shares,  (iv) dividends on Preferred Shares
payable in  Preferred  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 Preferred Shares shall not be taxable to such shareholders.

     (n) The Company  covenants  and agrees that it shall not, at any time after
the  Distribution  Date,  (i)  consolidate  with any other Person  (other than a
Subsidiary  of the Company in a  transaction  which  complies with Section 11(o)
hereof),  (ii) merge with or into any other Person  (other than a Subsidiary  of
the Company in a transaction  which complies with Section 11(o) hereof, or (iii)
sell or  transfer  (or  permit  any  Subsidiary  to sell  or  transfer),  in one
transaction,  or a series  of  related  transactions,  assets or  earning  power
aggregating  more than 50% of the assets or earning power of the Company and its
Subsidiaries  (taken as a whole) to any other Person or Persons  (other than the
Company and/or any of its  subsidiaries in one or more transaction each of which
complies with Section 11(o) hereof),  if (x) at the time of or immediately after
such  consolidation,  merger or sale  there are any  rights,  warrants  or other
instruments  or  securities  outstanding  or  agreements  in effect  which would
substantially  diminish  or  otherwise  eliminate  the  benefits  intended to be
afforded by the Rights or (y) prior to, simultaneously with or immediately after
such  consolidation,  merger  or  sale,  the  shareholders  of  the  Person  who
constitutes,  or would constitute, the "Principal Party" for purposes of Section
13(a) hereof shall have received a distribution  of Rights  previously  owned by
such Person or any of its Affiliates and Associates.

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

     (p)   Anything   in  this   Agreement   or  the  Rights  to  the   contrary
notwithstanding,  in the event that at any time after the date of this Agreement
and prior to the  Distribution  Date,  the Company  shall (i) declare or pay any
dividend  on the  Common  Shares  payable  in  Common  Shares  or (ii)  effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or otherwise  than by payment of  dividends in Common  Shares)
into a greater or lesser number of Common Shares,  then in any such case (i) the
number of one  one-hundredths  of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one  one-hundredths of a Preferred Share 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 (ii) 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(p) shall be made  successively  whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is  effected.  If an event  occurs  which  would  require  an  adjustment  under
Section 11(a)(ii)  and this Section_11(p),  the adjustments provided for in this
Section 11(p) shall be in addition and prior to any adjustment required pursuant
to Section 11(a)(ii).
<PAGE>
     Section 12.  Certificate  of Adjusted  Purchase  Price or Number of Shares.
Whenever  an  adjustment  is made as provided in Sections 11 and 13, the Company
shall promptly (a) prepare a certificate  setting forth such  adjustment,  and a
brief statement of the facts accounting for such  adjustment,  (b) file with the
Rights Agent and with each transfer agent for the Common Shares or the Preferred
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.

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

     (a) In the  event  that,  on or  following  the  Shares  Acquisition  Date,
directly or indirectly,

     (i) the Company shall  consolidate  with, or merge with and into, any other
Person (other than a Subsidiary of the Company in a transaction  which  complies
with Section  11(o)) and the Company  shall not be the  continuing  or surviving
corporation of such consolidation or merger,

     (ii) any Person  (other than a Subsidiary  of the Company in a  transaction
which  complies with Section  11(o)) shall  consolidate  with, or merge with and
into, the Company, the Company shall be the continuing or surviving  corporation
of such  consolidation  or merger and, in connection with such  consolidation or
merger,  all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person or cash or any other property,

     (iii)  the  Company  shall  effect  a  statutory  share  exchange  with the
outstanding  Common  Shares of the Company  being  exchanged  for stock or other
securities of any other Person, cash or property, or

     (iv) 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  in a
transaction which complies with Section 11(o)),

     then,  and in each such case,  except as  contemplated  by  Section  13(e),
proper  provision  shall be made so that (i) each  holder of a Right  (except as
otherwise  provided in Section 7(e)) shall thereafter have the right to receive,
upon the exercise thereof at the then current Purchase Price, in accordance with
the terms of this  Agreement  and in lieu of  Preferred  Shares,  such number of
validly  authorized and issued,  fully paid,  nonassessable and freely tradeable
Common Shares of the Principal  Party,  not subject to any liens,  encumbrances,
rights of first  refusal  or  adverse  claims,  as shall be equal to the  result
obtained by (x) multiplying the then current Purchase Price by the number of one
one-hundredths  of a Preferred Share for which a Right is,  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
number of such one  one-hundredths of a shares for which a Right was exercisable
immediately  prior to the first occurrence of the Section 11(a)(ii) Event by the
Purchase Price in effect immediately prior to the first occurrence), exercisable
and  (y)_dividing  that  product by 50% of the current per share market price of
the Common Shares of such Principal Party (determined pursuant to Section_11(d))
on the date of consummation of such Section_13 Event;  (ii)_such Principal Party
shall  thereafter  be liable for,  and shall  assume,  by virtue of such merger,
consolidation,  statutory share exchange,  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,  it  being
specifically intended that the provisions of Section 11 shall apply only to such
Principal  Party  following  the first  occurrence  of a Section  13 Event;  and
(iv)_such Principal Party shall take such steps (including,  but not limited to,
the  reservation  of a  sufficient  number of its  Common  Shares to permit  the
exercise of all outstanding  Rights) in connection with the  consummation of any
such  transaction  as may be  necessary  to assure that the  provisions  of this
Agreement  shall  thereafter be  applicable,  as nearly as reasonably may be, in
relation to its Common Shares  thereafter  deliverable  upon the exercise of the
Rights.

     (b) "Principal Party" shall mean:

     (i) in the case of any transaction  described in clauses (w), (x) or (y) of
the first  sentence  of  Section  13(a),  the  Person  that is the issuer of any
securities into which Common Shares of the Company are converted in such merger,
consolidation or exchange, or if no securities are so issued, the Person that is
the other party to such merger, consolidation or exchange; 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 or have not been  continuously  over the  preceding
12-month period registered under Section 12 of the Exchange Act, and such Person
is a direct or indirect  Subsidiary 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,  unreserved Common
Shares which have not been issued or are held in treasury 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 providing that, as soon
as practicable after the date of any Section 13 Event, the Principal Party will:

     (i) prepare and file a registration  statement  under the Act, with respect
to the Rights and the securities  purchasable upon exercise of the Rights, on an
appropriate form, and 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 Act)
until  the  earlier  of  (1) the  date as of  which  the  Rights  are no  longer
exercisable for such securities or (2) the Final Expiration Date;

     (ii) take such action as may be appropriate  under, or to ensure compliance
with, the securities or "blue sky" laws of the various states in connection with
the exercisability of the Rights; and

     (iii) 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.
<PAGE>
     (d) 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 consummation of such transaction,  would
substantially  diminish  or  otherwise  eliminate  the  benefits  intended to be
afforded  by the  Rights.  Without  limiting  the  generality  of the  preceding
sentence, in case the Principal Party which is to be a party to a transaction of
the kind referred to in this Section 13 has a provision in any of its authorized
securities  or in its articles of  incorporation  or bylaws or other  instrument
governing its corporate  affairs,  which  provision would have the effect of (i)
causing such Principal Party to issue,  in connection  with, or as a consequence
of,  the  consummation  of a  transaction  of  the  kind  referred  to  in  this
Section_13,  Common Shares of such Principal Party at less than the then current
per share market price  (determined  pursuant to  Section_11(d))  or  securities
exercisable  for or convertible  into Common Shares of such  Principal  Party at
less than such then  current  market  price  (other  than to  holders  of Rights
pursuant to this Section_13) or (ii)_providing  for any special payment,  tax or
similar  provisions  in  connection  with the issuance of Common  Shares of such
Principal  Party pursuant to the provisions of Section_13;  then, in such event,
the Company shall not consummate any such  transaction  unless prior thereto the
provision in question of such Principal  Party shall have been canceled,  waived
or amended so as to avoid any of the effects referred to in clauses (i) and (ii)
of this paragraph,  or the authorized  securities  shall have been redeemed,  so
that the applicable  provision  will have no effect in connection  with, or as a
consequence of, the consummation of the proposed transaction.

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

     (f) The provisions of this Section 13 shall  similarly  apply to successive
mergers, consolidations, statutory share exchanges or sale or other transfers.

     Section 14. Fractional Rights and Fractional Shares.

     (a) The Company  shall not be required to issue  fractions  of Rights or to
distribute Right Certificates which evidence  fractional Rights. In lieu of such
fractional  Rights,  there shall be paid to the registered  holders of the Right
Certificates  with regard to which such  fractional  Rights  would  otherwise be
issuable  an amount in cash equal to the same  fraction  of the  current  market
value of a whole  Right.  For the purposes of this  Section  14(a),  the current
market  value of a whole Right shall be the closing  price of the Rights for the
Trading Day immediately  prior to the date on which such fractional Rights would
have been  otherwise  issuable.  The closing price for any day shall be the last
sale price,  regular  way, or, in case no such sale takes place on such day, the
average of the  closing  bid and asked  prices,  regular  way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities  listed or admitted to trading on the New York Stock  Exchange or,
if the  Rights  are not  listed or  admitted  to  trading  on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed 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 in the  over-the-counter  market,  as  reported  by NASDAQ or such  other
system then in use or, if on any such date the Rights are not quoted by any such
organization,  the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the  Company.  If on any such date no such market maker is making a
market in the Rights, the fair value of the Rights on such date as determined in
good faith by the Board of Directors of the Company shall be used.
<PAGE>
     (b) The  Company  shall not be  required to issue  fractions  of  Preferred
Shares (other than fractions which are integral  multiples of one  one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute  certificates
which  evidence  fractional  Preferred  Shares (other than  fractions  which are
integral  multiples of one  one-hundredth  of a Preferred  Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may,  at the  election of the  Company,  be  evidenced  by  depositary  receipts
pursuant to an  appropriate  agreement  between  the  Company  and a  depositary
selected  by it;  provided,  however,  that  if the  Company  issues  depositary
receipts  pursuant to any such agreement,  such agreement shall provide that the
holders of such  depositary  receipts shall have all the rights,  privileges and
preferences  to which they are entitled as  beneficial  owners of the  Preferred
Shares represented by such depositary receipts.  In lieu of fractional Preferred
Shares  that are not  integral  multiples  of one  one-hundredth  of a Preferred
Share, the Company shall pay to the registered  holders of Right Certificates at
the time such Rights are exercised as herein provided an amount in cash equal to
the same fraction of the current  market value of one Preferred  Share.  For the
purposes of this Section 14(b),  the current  market value of a Preferred  Share
shall be the  closing  price of a  Preferred  Share (as  determined  pursuant to
Section  11(d))  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
the holder's  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,  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 such holder's own behalf and
for such holder's own benefit, enforce, and may institute and maintain any suit,
action or proceeding against the Company to enforce, or otherwise act in respect
of,  such  holder's  right  to  exercise  the  Rights  evidenced  by such  Right
Certificate  in the  manner  provided  in  such  Right  Certificate  and in this
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; and

     (c) subject to Section  6(a) and Section  7(f),  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,  and  neither  the
Company nor the Rights  Agent  shall be affected by any notice to the  contrary;
and

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

     Section 17. Right Certificate  Holder Not Deemed a Shareholder.  No holder,
as such, of any Right Certificate  shall be entitled to vote,  receive dividends
or be deemed for any  purpose  the holder of the  Preferred  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 shareholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
shareholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
shareholders  (except as provided in Section  25),  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 of
this Agreement.

     Section 18. Concerning the Rights Agent.

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

     (b) The Rights Agent shall be protected  and shall incur no liability  for,
or in respect of any action taken, suffered or omitted by it in connection with,
its  administration  of this Agreement in reliance upon any Right Certificate or
certificate  for the  Preferred  Shares  (or for  scrip or  depositary  receipts
evidencing  fractional  interests in Preferred  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.

     Section 19. Merger or Consolidation or Change of Name of Rights Agent.

     (a) Any  corporation  into which the Rights Agent or any  successor  Rights
Agent may be merged or with  which it may be  consolidated,  or any  corporation
resulting  from any merger or  consolidation  to which the  Rights  Agent or any
successor  Rights Agent shall be a party, or any  corporation  succeeding to the
stock transfer or corporate  trust business of the Rights Agent or any successor
Rights Agent,  shall be the  successor to the Rights Agent under this  Agreement
without the  execution  or filing of any paper or any further act on the part of
any of the parties to this Agreement,  provided that such  corporation  would be
eligible for  appointment  as a successor  Rights Agent under the  provisions of
Section 21. 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.
<PAGE>

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

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

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

     (b)  Whenever in the  performance  of its duties under this  Agreement  the
Rights Agent shall deem it  necessary  or  desirable  that any fact or matter be
proved or  established  by the Company  prior to taking or suffering  any action
hereunder,  such fact or matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed)  may be deemed to be  conclusively  proved and
established by a certificate signed by any one of the Chairman of the Board, the
President, any Vice 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 of this  Agreement
(except the due  execution of this  Agreement 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)) 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  receipt  of  actual  notice  from the  Company  stating  that a change or
adjustment is required and specifying the manner and amount thereof);  nor shall
it by any act hereunder be deemed to make any  representation  or warranty as to
the  authorization  or reservation of any Preferred Shares to be issued pursuant
to this Agreement or any Right Certificate or as to whether any Preferred 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,  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 to be taken by it in good faith in  accordance
with  instructions  of any such officer or for any delay in acting while waiting
for those instructions.
<PAGE>

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

     (k) If, with  respect to any 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 and/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.

     Section  21.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Shares and Preferred  Shares by registered or certified  mail, and
to the holders of the Right  Certificates  by first-class  mail. The Company may
remove the Rights  Agent or any  successor  Rights Agent upon 30 days' notice in
writing,  mailed to the Rights Agent or successor  Rights Agent, as the case may
be, and to each  transfer  agent of the Common  Shares and  Preferred  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 30 days  after  giving  notice of such  removal  or after it has been
notified  in writing of such  resignation  or  incapacity  by the  resigning  or
incapacitated  Rights Agent or by the holder of a Right  Certificate (who shall,
with such notice,  submit the holder's Right  Certificate  for inspection by the
Company),  then the registered  holder of any Right Certificate may apply to any
court of competent  jurisdiction  for the appointment of a new Rights Agent. Any
successor  Rights  Agent,  whether  appointed by the Company or by such a court,
shall be (a) a  corporation  organized and doing  business under the laws of the
United States or of the State of Minnesota or New York (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 Minnesota or New York),  in good standing,
having  an office in the State of  Minnesota  or New York,  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 or is a subsidiary of a corporation which has at the time of its appointment
as Rights  Agent a combined  capital  and surplus of at least $100  million,  or
(b)_an  affiliate of a corporation  described in  clause (a)  of this  sentence.
After  appointment,  the  successor  Rights  Agent shall be vested with the same
powers,  rights,  duties and responsibilities as if it had been originally named
as Rights Agent without  further act or deed; but the  predecessor  Rights Agent
shall  deliver and  transfer to the  successor  Rights Agent any property at the
time held by it  hereunder,  and execute  and  deliver  any  further  assurance,
conveyance,  act or deed necessary for the purpose. Not later than the effective
date of any such  appointment  the Company shall file notice  thereof in writing
with the  predecessor  Rights Agent and each transfer agent of the Common Shares
and Preferred  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.
<PAGE>

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

     Section 23. Redemption.

     (a) At least a majority of the  Continuing  Directors may, at their option,
at any time prior to the earlier of (i) the Shares  Acquisition Date or (ii) the
Final Expiration Date,  redeem all but not less than all of the then outstanding
Rights  at a  redemption  price of $.01 per  Right,  appropriately  adjusted  to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date of this Agreement (such redemption price being hereinafter  referred to
as the  "Redemption  Price").  The  redemption  of the Rights by the  Continuing
Directors  may be made  effective  at such time and on such  basis and with such
conditions as the Continuing  Directors in their sole  discretion may establish.
The Company may, at its option,  pay the Redemption Price in cash, Common Shares
(based on the "current  market price",  as defined in Section  11(d)(i),  of the
Common Shares at the time of the redemption) or any other form of  consideration
deemed appropriate by a majority of the Continuing Directors; provided, however,
that if the Company  elects to pay the Redemption  Price in Common  Shares,  the
Company shall not be required to issue any  fractional  Common  Shares,  and the
number of shares  issuable to each holder of Rights shall be rounded down to the
next whole number.

     (b) Immediately  upon the action of the Continuing  Directors  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 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 that
specifically  set forth in this  Section 23 or in Section  24, and other than in
connection with the purchase of Common Shares prior to the Distribution Date.

     Section 24. Exchange.

     (a) At least a majority of the  Continuing  Directors may, at their 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)),  for Common
Shares,  with each Right to be  exchanged  for such  number of Common  Shares as
shall equal the result  obtained by dividing (x) the  Purchase  Price by (y) the
current market price of the Common Shares (determined  pursuant to Section 11(d)
(such number of shares being hereinafter  referred to as the "Exchange  Ratio").
The Exchange Ratio shall be  appropriately  adjusted to reflect any stock split,
stock  dividend  or  similar  transaction  occurring  after  the  date  of  this
Agreement.  Notwithstanding the foregoing, the Continuing Directors shall not be
empowered  to effect such  exchange at any time after any Person  (other than an
Exempt  Person)  together  with all  Affiliates  and  Associates of such Person,
becomes  the  Beneficial  Owner  of  50%  or  more  of the  Common  Shares  then
outstanding.

     (b) Immediately  upon the action of the Continuing  Directors  ordering the
exchange of any Rights  pursuant to paragraph (a) of this Section 24 and without
any further  action and without  any notice,  the right to exercise  such Rights
shall  terminate and the only right  thereafter of a holder of such Rights shall
be to receive  that number of Common  Shares  equal to the number of such Rights
held by such holder multiplied by the Exchange Ratio. The Company shall promptly
give public notice of any such exchange;  provided, however, that the failure to
give,  or any defect in,  such  notice  shall not  affect the  validity  of such
exchange.  The Company  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  outstanding  and
exercisable  Rights  (other than Rights  which have become void  pursuant to the
provisions of Section 11(a)(ii)) held by each holder of Rights.

     (c)  In  the  event  that  there  shall  not be  sufficient  Common  Shares
authorized  but  unissued  and  unreserved  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.  In the event the Company  shall,  after good faith
effort,  be unable to take all such action as may be necessary to authorize such
additional Common Shares,  the Company shall  substitute,  for each Common Share
that would otherwise be issuable upon exchange of a Right, a number of Preferred
Shares or fraction  thereof  such that the current per share market price of one
Preferred  Share  multiplied  by such number or fraction is equal to the current
per share  market  price of one Common  Share as of the date of issuance of such
Preferred Shares or fraction thereof.

     (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  sentence
of  Section  11(d)(i))  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  Preferred  Shares or to make any other
distribution  to the  holders  of its  Preferred  Shares  (other  than a regular
quarterly cash dividend),  (ii) to offer to the holders of its Preferred  Shares
rights or warrants to  subscribe  for or to purchase  any  additional  Preferred
Shares  or  shares  of stock of any  class or any  other  securities,  rights or
options,  (iii) to effect any  reclassification  of its Preferred  Shares (other
than a reclassification  involving only the subdivision of outstanding Preferred
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, (v)_to effect any statutory share exchange with the
outstanding  Common  Shares of the Company  being  exchanged  for stock or other
securities of any other  corporation or cash or other  property,  (vi) to effect
the liquidation,  dissolution or winding up of the Company,  or (vii) to declare
or pay any dividend on the Common Shares payable in Common Shares or to effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or otherwise  than by payment of dividends in Common  Shares),
then,  in each such  case,  the  Company  shall  give to each  holder of a Right
Certificate,  in accordance  with Section 26, 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 and/or Preferred 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) of
this  paragraph  at least  ten days  prior to the  record  date for  determining
holders of the Preferred Shares for purposes of such action,  and in the case of
any such other action, at least ten days prior to the date of the taking of such
proposed  action or the date of  participation  therein  by the  holders  of the
Common Shares and/or Preferred Shares, whichever shall be the earlier.

     (b) In case the event set forth in Section  11(a)(ii) shall occur, then the
Company shall as soon as practicable  thereafter  give to each holder of a Right
Certificate,  in accordance  with Section 26, 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).

                           CERTIFICATE OF DESIGNATION
                                       OF
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                                       OF
                              POSSIS MEDICAL, INC.



     The  undersigned  hereby  certifies  that the Board of  Directors of Possis
Medical,  Inc. (the "Corporation"),  a corporation  organized and existing under
the Minnesota Business Corporation Act, duly adopted the following resolution on
December 11, 1996:

     RESOLVED,  that a series of preferred  stock of the  Corporation  is hereby
created,  and the  designation  and amount  thereof and the relative  rights and
preferences of the shares of such series, are as follows:

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

     Section 2. Dividends and Distributions.

     (a)  Subject  to the  rights of the  holders of any shares of any series of
preferred  stock  (or any  similar  stock)  ranking  prior and  superior  to the
Preferred Shares with respect to dividends,  the holders of Preferred Shares, in
preference  to the  holders  of Common  Stock,  par value  $0.40 per share  (the
"Common  Stock"),  of the Corporation,  and of any other junior stock,  shall be
entitled to receive,  when,  as and if declared by the Board of Directors out of
funds legally available for the purpose,  quarterly dividends payable in cash on
the first day of March,  June,  September  and  December in each year (each such
date  being  referred  to  herein  as  a  "Quarterly  Dividend  Payment  Date"),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share or fraction of a share of  Preferred  Shares,  in an amount per share
(rounded to the nearest  cent) equal to the greater of (i) $0.01 or (ii) subject
to the provision for adjustment  hereinafter set forth,  100 times the aggregate
per share amount of all cash  dividends,  and 100 times the  aggregate per share
amount (payable in kind) of all non-cash dividends or other distributions, other
than a  dividend  payable  in  shares of Common  Stock or a  subdivision  of the
outstanding shares of Common Stock (by reclassification or otherwise),  declared
on the Common Stock since the immediately  preceding  Quarterly Dividend Payment
Date or, with respect to the first Quarterly  Dividend  Payment Date,  since the
first issuance of any share or fraction of a share of Preferred  Shares.  In the
event the Corporation shall at any time after December 23, 1996,  declare or pay
any dividend on the Common Stock payable in shares of Common Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification  or  otherwise)  into a greater or lesser  number of
shares of Common  Stock,  then in each such case the amount to which  holders of
shares of Preferred Shares were entitled  immediately  prior to such event under
clause (ii) of the  preceding  sentence  shall be adjusted by  multiplying  such
amount by a fraction,  the  numerator of which is the number of shares of Common
Stock  outstanding  immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding  immediately prior to
such event. 
<PAGE>

     (b) The  Corporation  shall  declare  a  dividend  or  distribution  on the
Preferred Shares as provided in paragraph (a) of this Section  immediately after
it  declares a  dividend  or  distribution  on the Common  Stock  (other  than a
dividend  payable in shares of Common Stock or a subdivision of the  outstanding
Common  Stock);  provided that, in the event no dividend or  distribution  shall
have been  declared on the Common Stock during the period  between any Quarterly
Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a
dividend  of $0.01 per  share on the  Preferred  Shares  shall  nevertheless  be
payable,  out of funds legally  available for such purpose,  on such  subsequent
Quarterly Dividend Payment Date.

     (c) Dividends shall begin to accrue and be cumulative on outstanding shares
of Preferred Shares from their date of issue. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Preferred Shares in an amount
less than the total amount of such  dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. The Board of Directors may fix a record date for
the  determination of holders of Preferred Shares entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

     Section 3. Voting Rights.

     (a) Subject to the provision for  adjustment  hereinafter  set forth,  each
Preferred  Share shall  entitle  the holder  thereof to 100 votes on all matters
submitted to a vote of the  shareholders  of the  Corporation.  In the event the
Corporation  shall at any time  after  December  23,  1996,  declare  or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification  or  otherwise)  into a greater or lesser  number of
shares of Common Stock,  then in each such case the number of votes per share to
which holders of shares of Preferred Shares were entitled  immediately  prior to
such event  shall be  adjusted by  multiplying  such  number by a fraction,  the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

     (b) Except as otherwise provided herein or by law, the holders of Preferred
Shares  and the  holders  of Common  Stock and any  other  capital  stock of the
Corporation having general voting rights shall vote together as one class on all
matters submitted to a vote of shareholders of the Corporation.

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

     Section 4. Certain Restrictions.

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

     (i)  declare  or pay  dividends,  or make any other  distributions,  on any
shares of stock  ranking  junior  (either as to dividends  or upon  liquidation,
dissolution or winding up) to the Preferred Shares;

     (ii)  declare or pay  dividends,  or make any other  distributions,  on any
shares of stock ranking on a parity (either as to dividends or upon liquidation,
dissolution  or winding up) with the Preferred  Shares,  except  dividends  paid
ratably on the Preferred Shares and all such parity stock on which dividends are
payable or in arrears in proportion to the total amounts to which the holders of
all such shares are then entitled;
<PAGE>
     (iii) redeem or purchase or otherwise acquire for  consideration  shares of
any  stock  ranking  junior  (either  as  to  dividends  or  upon   liquidation,
dissolution or winding up) to the Preferred Shares; provided,  however, that the
Corporation may at any time redeem,  purchase or otherwise acquire shares of any
such junior stock in exchange for shares of any stock of the Corporation ranking
junior (either as to dividends or upon  dissolution,  liquidation or winding up)
to the Preferred Shares; or

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

     (b) The  Corporation  shall not permit any subsidiary of the Corporation to
purchase  or  otherwise  acquire  for  consideration  any shares of stock of the
Corporation unless the Corporation could, under paragraph (a) of this Section_4,
purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.  Reacquired  Shares. Any Preferred Shares purchased or otherwise
acquired  by the  Corporation  in any manner  whatsoever  shall be  retired  and
canceled  promptly  after the  acquisition  thereof.  All such shares shall upon
their cancellation  become authorized but unissued shares of preferred stock and
may be  reissued  as part of a new  series of  preferred  stock  subject  to the
conditions  and  restrictions  on issuance set forth herein,  in the Articles of
Incorporation,  or in any other certificate of designation  creating a series of
preferred stock or any similar stock or as otherwise required by law.

     Section 6.  Liquidation,  Dissolution or Winding Up. Upon any  liquidation,
dissolution or winding up of the Corporation,  no distribution shall be made (1)
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation,  dissolution or winding up) to the Preferred  Shares unless,  prior
thereto,  the holders of Preferred Shares shall have received the greater of (i)
$100 per  share,  plus an amount  equal to  accrued  and  unpaid  dividends  and
distributions thereon,  whether or not declared, to the date of such payment, or
(ii) an aggregate  amount per share,  subject to the  provision  for  adjustment
hereinafter set forth, equal to 100 times the aggregate amount to be distributed
per share to holders of Common Stock,  or (2) to the holders of stock ranking on
a parity (either as to dividends or upon liquidation, dissolution or winding up)
with the Preferred Shares,  except  distributions  made ratably on the Preferred
Shares and all such parity stock in proportion to the total amounts to which the
holders of all such shares are entitled upon such  liquidation,  dissolution  or
winding up. In the event the  Corporation  shall at any time after  December 23,
1996,  declare  or pay any  dividend  on the Common  Stock  payable in shares of
Common Stock,  or effect a subdivision or combination  or  consolidation  of the
outstanding  shares of Common Stock (by  reclassification  or otherwise)  into a
greater or lesser number of shares of Common  Stock,  then in each such case the
aggregate  amount to which  holders of shares of Preferred  Shares were entitled
immediately  prior to such event under clause (1)(ii) of the preceding  sentence
shall be adjusted by  multiplying  such amount by a fraction  the  numerator  of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.
<PAGE>
     Section 7. Consolidation,  Merger, etc. In case the Corporation shall enter
into any  consolidation,  merger,  combination or other transaction in which the
shares  of  Common  Stock are  exchanged  for or  changed  into  other  stock or
securities,  cash and/or any other property, then in any such case each share of
Preferred  Shares shall at the same time be similarly  exchanged or changed into
an amount per share,  subject to the provision for  adjustment  hereinafter  set
forth, equal to 100 times the aggregate amount of stock, securities, cash and/or
any other  property  (payable  in kind),  as the case may be,  into which or for
which each  share of Common  Stock is  changed  or  exchanged.  In the event the
Corporation  shall at any time  after  December  23,  1996,  declare  or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification  or  otherwise)  into a greater or lesser  number of
shares of Common  Stock,  then in each  such  case the  amount  set forth in the
preceding sentence with respect to the exchange or change of shares of Preferred
Shares shall be adjusted by multiplying such amount by a fraction, the numerator
of which is the number of shares of Common Stock  outstanding  immediately after
such event and the  denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

     Section 8. No  Redemption.  The  shares of  Preferred  Shares  shall not be
redeemable.

     Section 9. Rank.  The  Preferred  Shares  shall rank,  with  respect to the
payment of dividends and the distribution of assets, junior to all series of any
other class of the Corporation's preferred stock.

     Section 10. Fractional Shares.  Preferred Shares may be issued in fractions
of a share which are integral  multiples of one  one-hundredth  of a share which
shall entitle the holder, in proportion to such holder's  fractional  shares, to
receive  dividends,  participate in distributions and to have the benefit of all
other rights of holders of Preferred Shares.

     Section 11.  Amendment.  The Articles of  Incorporation  of the Corporation
shall not be amended in any manner  which would  materially  alter or change the
powers,  preferences  or rights  of the  Preferred  Shares so as to affect  them
adversely  without the affirmative vote of the holders of at least two-thirds of
the outstanding shares of Preferred Shares, voting together as a single class.

     IN WITNESS  WHEREOF,  I have  subscribed  my name this ___ day of December,
1996.

Certificates for the number of whole Rights not exercised.

thereof a cash payment will be made, as provided in the Rights Agreement.

     No holder of this Right  Certificate  shall be  entitled to vote or receive
dividends or be deemed for any purpose the holder of the Preferred  Shares or of
any other  securities  of the  Company  which may at any time be issuable on the
exercise hereof,  nor shall anything contained in the Rights Agreement or herein

withhold  consent to any corporate  action,  or to receive notice of meetings or
other  actions  affecting   shareholders  (except  as  provided  in  the  Rights

 Exhibit C


                              POSSIS MEDICAL, INC.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES




     On December 11, 1996, the Board of Directors of Possis  Medical,  Inc. (the
"Company"),  declared  a  dividend  of one  preferred  share  purchase  right (a
"Right") per share for each  outstanding  share of Common Stock,  par value $.40
(the "Common Shares"),  of the Company.  The dividend is payable on December 23,
1996 (the "Record Date") to shareholders of record on that date.

     Each Right entitles the registered  holder to purchase from the Company one
one-hundredth of a share of Series A Junior  Participating  Preferred Stock, par
value $.40 (the  "Preferred  Shares"),  of the Company at a price of $160.00 per
one-hundredth  of  a  Preferred  Share  (the  "Purchase   Price"),   subject  to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement (the "Rights  Agreement"),  dated as of December 12, 1996, between the
Company and Norwest Bank Minnesota,  National Association,  as Rights Agent (the
"Rights Agent").

     Initially,  the Rights will be evidenced by the  certificates  representing
Common  Shares then  outstanding  and no  separate  Right  Certificates  will be
distributed. The Rights will separate from the Common Shares, and a Distribution
Date for the Rights will occur upon the earlier of: (i) the first date of public
announcement  that a Person or group of  affiliated  or  associated  Persons has
become an "Acquiring Person" (i.e., has become,  subject to certain  exceptions,
the beneficial  owner of 15% or more of the  outstanding  Common Shares) (except
pursuant to a Permitted  Offer,  as  hereinafter  defined) and (ii) the 10th day
following the commencement or public  announcement of a tender offer or exchange
offer, the consummation of which would result in a Person or group of affiliated
or associated Persons becoming,  subject to certain  exceptions,  the beneficial
owner of 15% or more of the outstanding Common Shares (or such later date as may
be  determined  by the Board of  Directors  of the Company  prior to a Person or
group of  affiliated or associated  Persons  becoming an Acquiring  Person) (the
earlier of such dates being called the "Distribution Date").

     Until the Distribution Date, (i) the Rights will be evidenced by the Common
Share certificates and will be transferred with and only with the Common Shares,
(ii) new Common Share certificates issued after the Record Date upon transfer or
new  issuance of the Common  Shares will  contain a notation  incorporating  the
Rights  Agreement  by  reference,  and (iii) the  surrender  for transfer of any
Common Share  certificate,  even without such notation or a copy of this Summary
of Rights  attached  thereto,  will also  constitute  the transfer of the Rights
associated with the Common Shares represented by such certificate.

     As  promptly as  practicable  following  the  Distribution  Date,  separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution  Date, and such separate Right Certificates alone will evidence the
Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on December 23, 2006, unless extended or earlier redeemed or exchanged by
the Company as described below.
<PAGE>

     The  Purchase  Price  payable and the number of  Preferred  Shares or other
securities  or  property  issuable  upon  exercise  of the Rights are subject to
adjustment  from time to time to prevent  dilution:  (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares,  (ii) upon the  grant to  holders  of the  Preferred  Shares of  certain
rights,  options or warrants to subscribe  for or purchase  Preferred  Shares or
convertible  securities  at less  than  the  then  current  market  price of the
Preferred  Shares,  or (iii) upon the  distribution  to holders of the Preferred
Shares of evidences of indebtedness or assets  (excluding  regular periodic cash
dividends or dividends payable in Preferred Shares) or of subscription rights or
warrants  (other than those  described in clause (ii) of this  paragraph).  With
certain  exceptions,  no adjustment in the Purchase Price will be required until
cumulative  adjustments  require an  adjustment  of at least 1% in the  Purchase
Price.

     No  fraction  of a  Preferred  Share  (other  than  fractions  in  integral
multiples of one  one-hundredth of a share) will be issued and, in lieu thereof,
an  adjustment  in cash  will be made  based  on the  closing  price on the last
trading date prior to the date of exercise.

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

     Preferred  Shares  purchasable  upon  exercise  of the  Rights  will not be
redeemable.  Each  Preferred  Share will be entitled  to a minimum  preferential
quarterly  dividend  payment  of $.01  per  share  but  will be  entitled  to an
aggregate  dividend of 100 times the dividend  declared per Common Share. In the
event of liquidation,  the holders of the Preferred Shares will be entitled to a
minimum preferential  liquidation payment of $.01 per share but will be entitled
to an  aggregate  payment of 100 times the payment made per Common  Share.  Each
Preferred  Share will have 100 votes,  voting  together with the Common  Shares.
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged,  each  Preferred  Share will be entitled to receive
100 times the amount  received  per Common  Share.  These  rights are subject to
adjustment  in  the  event  of a  stock  dividend  on  the  Common  Shares  or a
subdivision, combination or consolidation of the Common Shares.

     In the event that a person or group  becomes an  Acquiring  Person  (except
pursuant to a Permitted Offer (as defined below)), each holder of a Right, other
than the Acquiring Person or the affiliates,  associates or transferees  thereof
(whose  Rights  will  thereafter  be void),  will  thereafter  have the right to
receive upon exercise  thereof at the then current  exercise  price of the Right
that number of Common  Shares  having a market  value of two times the  exercise
price of the Right, subject to certain possible adjustments.

     In the event that the  Company  is  acquired  in  certain  mergers or other
business combination  transactions or 50% or more of the assets or earning power
of the Company and its  subsidiaries  (taken as a whole) are sold after a person
or group becomes an Acquiring  Person  (except  pursuant to a Permitted  Offer),
holders of the Rights will thereafter  have the Right to receive,  upon exercise
thereof at the then current  exercise price of the Right,  that number of Common
Shares of the acquiring  company (or, in certain cases,  one of its  Affiliates)
having a market value of two times the exercise price of the Right.

     A  "Permitted  Offer"  is a  tender  offer  or an  exchange  offer  for all
outstanding Common Shares of the Company at a price and on terms determined by a
majority of the Board of  Directors  of the Company who are not  officers of the
Company and who are not  Acquiring  Persons or  affiliates  or  associates of an
Acquiring Person and after receiving advice from one or more investment  banking
firms, to be (a) fair to shareholders (taking into account all factors which the
Board of Directors  deems  relevant) and (b) otherwise in the best  interests of
the Company and its shareholders employees,  customers,  suppliers and creditors
and the  communities in which the Company does business,  and which the Board of
Directors determines to recommend to the shareholders of the Company.
<PAGE>

     At any time after a Person becomes an Acquiring  Person (subject to certain
exceptions),  and  prior to the  acquisition  by a Person  of 50% or more of the
outstanding Common Shares, the Continuing  Directors may exchange all or part of
the Rights for Common Shares at an exchange  ratio per Right equal to the result
obtained  by  dividing  the  exercise  price of a Right by the current per share
market price of the Common Shares, subject to adjustment.

     At any time before a Person has become an Acquiring Person,  the Continuing
Directors  may redeem the Rights in whole,  but not in part,  at a price of $.01
per Right (the "Redemption Price"), subject to adjustment. The redemption of the
Rights  may be made  effective  at  such  time,  on such  basis  and  with  such
conditions  as  such  Continuing   Directors  may,  in  their  sole  discretion,
establish.

     A  "Continuing  Director" is a member of the Board of  Directors  who was a
member of the Board on December 23, 1996, or who subsequently  became or becomes
a member of the Board of  Directors  with the  recommendation  or  approval of a
majority of the Continuing  Directors.  Continuing  Directors do not include any
Acquiring Person or affiliate or associate of an Acquiring Person.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a shareholder of the Company,  including without limitation, the right
to vote or to receive dividends.

     A copy of the  Rights  Agreement  has been filed  with the  Securities  and
Exchange Commission as an Exhibit to a Registration  Statement on Form 8-A dated
December 12, 1996.  A copy of the Rights  Agreement is available  free of charge
from the Company by  contacting  the  Secretary at Possis  Medical,  Inc.,  9055
Evergreen  Blvd.,  N.W.,   Minneapolis,   Minnesota  55433-8003.   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.
