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

              On February  17, 1998,  the Board of Directors of Advanced Machine
              Vision  Corporation  (the   "Corporation")   declared  a  dividend
              distribution of one preferred share purchase right (a "Right") for
              each outstanding  share of Class A Common Stock and Class B Common
              Stock,   without  par  value  (the   "Common   Shares"),   of  the
              Corporation. The dividend is payable to the shareholders of record
              on February  27, 1998 (the  "Record  Date"),  and with  respect to
              Common Shares issued  thereafter until the  Distribution  Date (as
              defined  below) and,  in certain  circumstances,  with  respect to
              Common  Stock issued after the  Distribution  Date.  Except as set
              forth below, each Right, when it becomes exercisable, entitles the
              registered   holder  to   purchase   from  the   Corporation   one
              one-hundredth  of  a  share  of  Series  A  Junior   Participating
              Preferred Stock,  without par value (the "Preferred  Shares"),  of
              the  Corporation  at a price  of $15 per  one  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")  between the  Corporation  and
              American  Stock  Transfer & Trust  Company,  as Rights  Agent (the
              "Rights Agent") dated as of February 27, 1998.

              Initially,  the  Rights  will  be  attached  to  all  certificates
              representing Common Shares then outstanding, and no separate Right
              Certificates  will be  distributed.  The Rights will separate from
              the Common Shares upon the earliest to occur of (i) ten days after
              a person or group of affiliated or associated persons has acquired
              beneficial  ownership  of 20% or  more of the  outstanding  Common
              Shares  (except  pursuant to a  Permitted  Offer,  as  hereinafter
              defined);  or (ii) 10  Business  Days (as  defined  in the  Rights
              Agreement)  (or  such  later  date  as the  Board  may  determine)
              following the  commencement of, or announcement of an intention to
              make, a tender offer or exchange offer the  consummation  of which
              would result in a person or group becoming an Acquiring Person (as
              hereinafter  defined) (the earliest of such dates being called the
              "Distribution  Date").  A person  or group  whose  acquisition  of
              Common  Shares causes a  Distribution  Date pursuant to clause (i)
              above is an  "Acquiring  Person."  The date that a person or group
              becomes an Acquiring Person is the "Shares Acquisition Date."

              The Rights Agreement  provides that, until the Distribution  Date,
              the Rights  will be  transferred  solely  with the Common  Shares.
              Until the Distribution  Date (or earlier  redemption or expiration
              of the  Rights),  new Common Share  certificates  issued after the
              Record Date upon  transfer or new  issuances of Common Shares will
              contain  a  notation   incorporating   the  Rights   Agreement  by
              reference.  Until the Distribution Date (or earlier  redemption or
              expiration  of the  Rights),  the  surrender  for  transfer of any
              certificates for Common Shares  outstanding as of the Record Date,
              even if such  notation or a copy of this  Summary of Rights is not
              attached thereto,  will also constitute the transfer of the Rights
              associated with the Common Shares represented by such certificate.
              As soon as practicable  following the Distribution Date,  separate
              certificates  evidencing the Rights ("Right Certificates") will be
              mailed to holders  of record of the Common  Shares as of the close
              of business on the  Distribution  Date (and to each initial record
              holder of certain  Common  Shares  issued  after the  Distribution
              Date),  and such separate Right  Certificates  alone will evidence
              the Rights.

              The Rights are not  exercisable  until the  Distribution  Date and
              will expire at the close of business on February 26, 2008,  unless
              earlier redeemed by the Corporation as described below.

              In the event that any person  becomes an Acquiring  Person (except
              pursuant  to  a  tender  or  exchange   offer  which  is  for  all
              outstanding Common Shares at a price and on terms which a majority
              of members of the Board of Directors (who are not also officers of
              the  Corporation or an Acquiring  Person or affiliate or associate
              thereof)  determines  to be adequate and in the best  interests of
              the  Corporation and its  shareholders,  other than such Acquiring
              Person, its affiliates and associates (a "Permitted Offer"),  each
              holder of a Right will  thereafter  have the right  (the  "Flip-In
              Right") to receive upon  exercise the number of Common Shares (or,
              in  certain  circumstances,  one  one-hundredths  of  a  share  of
              Preferred Shares or other securities of the Corporation)  having a
              market value  (immediately  before such triggering event) equal to
              two times the  exercise  price of the  Right.  At such  time,  all
              Rights that are beneficially  owned by the Acquiring Person or any
              affiliate, associate or transferee thereof will be null and void.

              In the event that, at any time  following  the Shares  Acquisition
              Date,  (i) the  Corporation  is  acquired  in a  merger  or  other
              business  combination  transaction  in which the holders of all of
              the outstanding  Common Shares immediately before the consummation
              of the  transaction  are not the  holders of all of the  surviving
              corporation's   voting  power,  or  (ii)  more  than  50%  of  the
              Corporation's assets or earning power are sold or transferred,  in
              either case with or to an  Acquiring  Person or any  affiliate  or
              associate  or any other  person in which  such  Acquiring  Person,
              affiliate  or  associate  has an interest or any person  acting on
              behalf of or in concert with such Acquiring  Person,  affiliate or
              associate, or, if in such transaction all holders of Common Shares
              are not treated alike,  then each holder of a Right (except Rights
              which  previously  have  been  voided as set  forth  above)  shall
              thereafter have the right (the "Flip-Over Right") to receive, upon
              exercise,  common shares of the acquiring  company  having a value
              equal to two times the exercise price of the Right.  The holder of
              a Right  will  continue  to have the  Flip-Over  Right only to the
              extent that the Flip-In Right has not previously been exercised.

              The Purchase  Price  payable and the number of  Preferred  Shares,
              Common  Shares or other  securities  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 or warrants to subscribe for or purchase  Preferred
              Shares at a price (or  conversion  price as the case may be), 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 quarterly
              cash dividends) or of subscription  rights or warrants (other than
              those referred to above).

              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,
              before 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 $1.00 per share but, if
              greater,  will be entitled to an  aggregate  dividend per share 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 $100 per share;
              thereafter,  and after the holders of the Common Shares  receive a
              liquidation  payment  of  $1.00  per  share,  the  holders  of the
              Preferred  Shares and the holders of the Common  Shares will share
              the remaining assets in the ratio of 1 to 1 (as adjusted) for each
              Preferred Share and Common Share so held,  respectively.  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  protected  by  customary  antidilution
              provisions.  In the event that the  amount of  accrued  and unpaid
              dividends  on the  Preferred  Shares  is  equivalent  to six  full
              quarterly  dividends  or more  (whether or not  consecutive),  the
              holders of the Preferred Shares shall have the right,  voting as a
              class,  to elect two directors  until all cumulative  dividends on
              the  Preferred  Shares have been paid  through the last  quarterly
              dividend payment date or until non-cumulative  dividends have been
              paid regularly for at least one year.

              With certain exceptions,  no adjustment to the Purchase Price will
              be required until cumulative  adjustments require an adjustment of
              at least 1% in such Purchase Price. No fractional Preferred Shares
              will be issued (other than fractions  which are one  one-hundredth
              or integral  multiples of one  one-hundredth of a Preferred Share,
              which may, at the  election of the  Corporation,  be  evidenced by
              depository  receipts) and in lieu thereof,  a payment in cash will
              be made based on the market price of the  Preferred  Shares on the
              last Trading Day (as defined in the Rights  Agreement)  before the
              date of exercise.

              At any time before the  earlier to occur of (i) a person  becoming
              an Acquiring  Person,  (ii) the expiration of the Rights, or (iii)
              in certain  circumstances,  after the Shares Acquisition Date, the
              Corporation  may redeem all but not less than all of the Rights at
              a price  of  $.0001  per  Right  (the  "Redemption  Price")  which
              redemption  shall be  effective  upon the  action  of the Board of
              Directors.

              All of the  provisions  of the Rights  Agreement may be amended by
              the Board of Directors of the Corporation  before the Distribution
              Date.  After the  Distribution  Date, the provisions of the Rights
              Agreement  may be  amended  by the  Board  in  order  to cure  any
              ambiguity,  defect or inconsistency,  to make changes which do not
              adversely affect the interests of holders of Rights (excluding the
              interests  of  any  Acquiring  Person),  or,  subject  to  certain
              limitations,  to shorten or  lengthen  any time  period  under the
              Rights Agreement.

              The  Rights  Agreement  is  attached  hereto  as  an  exhibit  and
              incorporated herein by reference. The foregoing description of the
              Rights is qualified by reference to such exhibit.

                                RIGHTS AGREEMENT


     RIGHTS AGREEMENT, dated as of February 27, 1998 (the "Agreement"),  between
Advanced   Machine   Vision   Corporation,   a   California   corporation   (the
"Corporation"),  and  American  Stock  Transfer  & Trust  Company  (the  "Rights
Agent").

     The Board of Directors of the  Corporation  has  authorized  and declared a
dividend of one common  share  purchase  right (a "Right") for each Common Share
(as defined herein) of the Corporation  outstanding at the Close of Business (as
defined  herein)  on  February  27,  1998  (the  "Record   Date"),   each  Right
representing  the right to purchase one  one-hundredth  of a Preferred Share (as
defined herein),  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  or the  Final
Expiration  Date (as such terms are defined  herein);  provided,  however,  that
Rights may be issued with respect to Common Shares that shall become outstanding
after the  Distribution  Date and before 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:

     (a)  "Acquiring  Person"  shall mean any Person (as defined  herein) who or
which,  together with all Affiliates and Associates (as defined  herein) of such
Person,  shall be the Beneficial Owner (as defined herein) of 20% or more of the
then outstanding  Common Shares (other than as a result of a Permitted Offer (as
defined  herein))  or was such a  Beneficial  Owner at any time  after  the date
hereof,  whether or not such person  continues to be the Beneficial Owner of 20%
or more of the then outstanding  Common Shares.  Notwithstanding  the foregoing,
(A) the term "Acquiring Person" shall not include (i) the Corporation,  (ii) any
Subsidiary  of  the  Corporation,   (iii)  any  employee  benefit  plan  of  the
Corporation or of any Subsidiary of the Corporation,  (iv) any Person organized,
appointed or established by the  Corporation for or pursuant to the terms of any
such plan,  (v) any of the executive  officers of Ventek,  Inc., a Subsidiary of
the  Corporation  (the  "Ventek  Officers"),  or (vi) any  Person,  who or which
together  with  all  Affiliates  and  Associates  of such  Person,  becomes  the
Beneficial  Owner  of 20% or more of the then  outstanding  Common  Shares  as a
result of the  acquisition of Common Shares directly from the  Corporation,  and
(B) no Person shall be deemed to be an "Acquiring Person" either (X) as a result
of the  acquisition of Common Shares by the  Corporation  which, by reducing the
number of Common Shares outstanding, increases the proportional number of shares
beneficially  owned by such Person,  together with all Affiliates and Associates
of such Person;  except that if (i) a Person  would  become an Acquiring  Person
(but for the operation of this  subclause X) as a result of the  acquisition  of
Common Shares by the Corporation,  and (ii) after such share  acquisition by the
Corporation,  such Person, or an Affiliate or Associate of such Person,  becomes
the Beneficial Owner of any additional Common Shares,  then such Person shall be
deemed an Acquiring  Person, or (Y) if the Board of Directors of the Corporation
determines  in good  faith that a Person who would  otherwise  be an  "Acquiring
Person," as defined  pursuant to the foregoing  provisions of this Section 1(a),
has become such, 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 Section 1(a),
then such Person shall not be deemed as  "Acquiring  Person" for any purposes of
this Agreement.

     (b) "Act"  shall mean the  Securities  Act of 1933,  as  amended  and as in
effect on the date of this Agreement.

     (c) "Affiliate" and "Associate" shall have the respective meanings ascribed
to such  terms in Rule  12b-2 of the  General  Rules and  Regulations  under the
Securities  Exchange  Act of 1934,  as amended and in effect on the date of this
Agreement (the "Exchange Act").

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

          (i) of  which  such  Person  or any of  such  Person's  Affiliates  or
     Associates directly or indirectly, has "beneficial ownership" as determined
     in accordance  with Rule 13d-3 of the General Rules and  Regulations  under
     the Exchange Act;

          (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 after  the  passage  of time)  pursuant  to any  agreement,
     arrangement or  understanding,  or upon the exercise of conversion  rights,
     exchange rights,  rights (other than the 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 or dispose of
     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 or  Schedule  13G 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) relating to the acquisition, holding, voting
     (except to the extent  contemplated by the proviso to Section  1(d)(ii)(B))
     or disposing of any securities of the Corporation.

     Notwithstanding  anything in this definition of Beneficial Ownership to the
contrary,  the phrase "then  outstanding,"  when used herein with reference to a
Person's Beneficial  Ownership of securities of the Corporation,  shall mean the
number of such securities  then issued and outstanding  together with the number
of such securities not then actually  issued and  outstanding  which such Person
would be deemed to own beneficially hereunder.

     (e) "Business Day" shall mean any day other than a Saturday, Sunday or U.S.
federal holiday.

     (f) "Close of  Business"  on any given  date  shall mean 5:00 P.M.,  Oregon
time, on such date; provided,  however,  that if such date is not a Business Day
it shall mean 5:00 P.M., Oregon time, on the next succeeding Business Day.

     (g) "Common Shares" when used with reference to the Corporation  shall mean
the shares of Class A Common Stock and Class B Common Stock,  without par value,
of  the  Corporation  or,  in  the  event  of  a  subdivision,   combination  or
consolidation  with  respect to such shares of Class A Common  Stock and Class B
Common  Stock,  the shares of Class A Common  Stock  and/or Class B Common Stock
resulting from such subdivision,  combination or consolidation.  "Common Shares"
when used with reference to any Person other than the Corporation shall mean the
capital stock (or equity  interest) with the greatest voting power of such other
Person or, if such other Person is a Subsidiary of another Person, the Person or
Persons which ultimately control such first-mentioned Person.

     (h)  "Distribution  Date"  shall  have the  meaning  set forth in Section 3
hereof.

     (i) "Final  Expiration  Date" shall have the meaning set forth in Section 7
hereof.

     (j)  "Interested  Shareholder"  shall  mean any  Acquiring  Person,  or any
Affiliate or Associate of an Acquiring  Person, or any other Person in which any
such  Acquiring  Person,  Affiliate or Associate  has an interest,  or any other
Person  acting  directly or  indirectly on behalf of or in concert with any such
Acquiring Person, Affiliate or Associate.

     (k)  "Permitted  Offer" shall mean a tender or exchange  offer which is for
all  outstanding  Common Shares at a price and on terms  determined,  before the
purchase of shares under such tender or exchange  offer,  by at least a majority
of the members of the Board of Directors who are not officers of the Corporation
and who  are not  Acquiring  Persons  or  Affiliates,  Associates,  nominees  or
representatives  of an Acquiring Person, to be adequate (taking into account all
factors  that such members of the Board of Directors  deem  relevant  including,
without limitation,  prices that could reasonably be achieved if the Corporation
or its assets were sold on an orderly basis  designed to realize  maximum value)
and  otherwise in the best  interests of the  Corporation  and its  shareholders
(other than the Person or any Affiliate or Associate  thereof on whose basis the
offer is being made)  taking into account all factors  that such  directors  may
deem relevant.

     (l) "Person" shall mean any  individual,  firm,  partnership,  corporation,
trust,  association,  joint  venture  or other  entity,  and shall  include  any
successor (by merger or otherwise) of such entity.

     (m) "Preferred  Shares" shall mean shares of Series A Junior  Participating

     (q)  "Shares  Acquisition  Date"  shall  mean  the  first  date  of  public
announcement  (which,  for purposes of this definition,  shall include,  without
limitation,  a report filed pursuant to the Exchange Act) by the  Corporation or
an Acquiring Person that an Acquiring Person has become such; provided, that, if
such Person is  determined  not to have become an Acquiring  Person  pursuant to
Section 1(b)(Y) hereof,  then no Shares Acquisition Date shall be deemed to have
occurred.

     (r)  "Subsidiary"  of any Person shall mean any corporation or other Person
of which a majority  of the  voting  power of the voting  equity  securities  or
equity interest is owned, directly or indirectly, by such Person.

     (s)  "Triggering  Event"  shall  mean any  Section  11(a)(ii)  Event or any
Section 13 Event.

     Section 2. Appointment of Rights Agent. The Corporation hereby appoints the
Rights Agent to act as agent for the  Corporation  and the holders of the Rights
(who, in accordance with Section 3 hereof,  shall before the  Distribution  Date
also be the  holders  of  Common  Shares)  in  accordance  with  the  terms  and
conditions  hereof,  and the Rights Agent hereby accepts such  appointment.  The
Corporation  may from time to time appoint such co-Rights  Agents as it may deem
necessary or desirable.

     Section 3. Issuance of Right Certificates.

     (a) Until the  earlier  of (i) the tenth day after the  Shares  Acquisition
Date or (ii) the Close of Business on the tenth Business Day (or such later date
as may be determined by action of the  Corporation's  Board of Directors)  after
the date on which any Person (other than the Corporation,  any Subsidiary of the
Corporation,  the Ventek Officers,  any employee benefit plan of the Corporation
or of any  Subsidiary  of the  Corporation  or any  Person or entity  organized,
appointed or established by the  Corporation for or pursuant to the terms of any
such plan)  commences or first publicly  announces the intent to commence (which
intention  to  commence  remains  in effect  for five  Business  Days after such
announcement), a tender or exchange offer the consummation of which would result
in any Person becoming an Acquiring Person  (including,  in the case of both (i)
and (ii), any such date which is after the date of this Agreement and before the
issuance of the Rights),  the earlier of such dates being herein  referred to as
the  "Distribution  Date," (x) the Rights will be  evidenced  by (subject to the
provisions of Section 3(b) hereof) the certificates for Common Shares registered
in the names of the holders thereof (which  certificates shall also be deemed to
be Right Certificates) and not by separate Right Certificates, and (y) the right
to receive Right  Certificates  will be transferable only in connection with the
transfer  of  the  underlying   Common  Shares  (including  a  transfer  to  the
Corporation);  provided,  however, that if a tender offer is terminated before a
Distribution  Date occurs,  then no Distribution Date shall occur as a result of
such tender offer.  As soon as  practicable  after the  Distribution  Date,  the
Corporation will prepare and execute, the Rights Agent will countersign, and the
Corporation will send or cause to be sent 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
Corporation, a Right Certificate,  substantially in the form of Exhibit B hereto
(a "Right Certificate"),  evidencing one Right for each Common Share so held. As
of and after the Distribution  Date, the Rights will be evidenced solely by such
Right Certificates.

     (b) As soon as practicable  following the Record Date, the Corporation will
send  a  copy  of  a  Summary  of  Rights  to  Purchase   Preferred  Shares,  in
substantially  the form of  Exhibit  C hereto  (the  "Summary  of  Rights"),  by
first-class,  postage-prepaid mail, to each record holder of Common Shares as of
the Close of Business on the Record Date, at the address of such holder shown on
the records of the  Corporation.  With respect to certificates for Common Shares
outstanding as of the Record Date, until the Distribution  Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together  with a copy of the  Summary  of  Rights  attached  thereto.  Until the
Distribution Date (or the earlier of the Redemption Date or the Final Expiration
Date),  the  surrender  for  transfer  of  any  certificate  for  Common  Shares
outstanding on the Record Date,  with or without a copy of the Summary of Rights
attached  thereto,  shall also constitute the transfer of the Rights  associated
with such Common Shares.

     (c) Certificates for Common Shares,  which become  outstanding  (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this  paragraph  (c)) after the  Record  Date but  before  the  earliest  of the
Distribution  Date, the Redemption Date or the Final  Expiration  Date, shall be
deemed also to be certificates for Rights and shall bear the following legend:

          This  certificate  also  evidences  and entities the holder  hereof to
     certain rights as set forth in a Rights Agreement  between Advanced Machine
     Vision Corporation and American Stock Transfer & Trust Company, dated as of
     February 20, 1998 (the "Rights  Agreement"),  the terms of which are hereby
     incorporated  herein  by  reference  and a copy of  which is on file at the
     principal executive offices of Advanced Machine Vision  Corporation.  Under
     certain  circumstances,  as set forth in the Rights Agreement,  such Rights
     will be evidenced by separate  certificates and will no longer be evidenced
     by this certificate.  Advanced Machine Vision  Corporation will mail to the
     holder of this  certificate a copy of the Rights  Agreement  without charge
     after receipt of a written request  therefor.  Under certain  circumstances
     set forth in the Rights Agreement, Rights issued to, or held by, any Person
     who is, was or becomes an  Acquiring  Person or an  Affiliate  or Associate
     thereof (as defined in the Rights  Agreement) and certain related  persons,
     whether  currently held by or on behalf of such Person or by any subsequent
     holder, may become null and void.

     With respect to such certificates  containing the foregoing  legend,  until
the Distribution  Date, the Rights associated with the Common Shares represented
by such  certificates  shall be evidenced by such  certificates  alone,  and the
surrender  for  transfer  of any such  certificate  shall  also  constitute  the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Corporation purchases or acquires any Common Shares after the
Record Date but before the  Distribution  Date, any Rights  associated with such
Common  Shares  shall be deemed  cancelled  and retired so that the  Corporation
shall not be entitled to exercise any Rights  associated  with the Common Shares
that are no longer outstanding.

     Section 4. Form of Right Certificate.

     (a) The Right  Certificates  (and the forms of election to purchase  and of
assignment to be printed on the reverse  thereof) shall be  substantially in the
form set forth in Exhibit A hereto and may have such marks of  identification or
designation and such legends,  summaries or endorsements  printed thereon as the
Corporation  may deem  appropriate  and as are consistent with the provisions of
this Agreement,  or as may-be required to comply with any applicable law or with
any rule or regulation  made pursuant  thereto or with any rule or regulation of
any stock  exchange  on which the Rights may from time to time be listed,  or to
conform to usage. Subject to the provisions of Section 11 and Section 22 hereof,
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 Preferred  Share set forth  therein (the  "Purchase  Price"),  but the
amount and type of  securities  purchasable  upon the exercise of each Right and
the Purchase Price thereof shall be subject to adjustment as provided herein.

     (b) Any Right  Certificate  issued  pursuant to Section  3(a) or Section 22
hereof that  represents  Rights which are null and void pursuant to Section 7(e)
of this  Agreement  and any Right  Certificate  issued  pursuant to Section 6 or
Section 11 hereof upon  transfer,  exchange,  replacement  or  adjustment of any
other Right  Certificate  referred to in this  sentence,  shall  contain (to the
extent feasible) the following legend:

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

     Provisions of Section 7(e) of this Agreement shall be operative  whether or
not the foregoing legend is contained on any such Right Certificate.

     Section 5. Countersignature and Registration.  The Right Certificates shall
be executed on behalf of the Corporation by its Chairman of the Board, its Chief
Executive Officer, its President, any of its Vice Presidents,  or its Treasurer,
either  manually  or by  facsimile  signature,  shall have  affixed  thereto the
Corporation's  seal  or a  facsimile  thereof,  and  shall  be  attested  by the
Secretary or an Assistant  Secretary of the  Corporation,  either manually or by
facsimile signature. The Right Certificates shall be countersigned by the Rights
Agent and shall be valid for any purpose unless so  countersigned.  In the event
that any  officer  of the  Corporation  who signs any of the Right  Certificates
ceases to be such officer of the Corporation before such countersignature by the
Rights  Agent  and  issuance  and  delivery  by  the  Corporation,   such  Right
Certificates  may  nevertheless be  countersigned by the Rights Agent and issued
and  delivered by the  Corporation  with the same force and effect as though the
person who signed such Right  Certificates  had not ceased to be such officer of
the  Corporation;  and any  Right  Certificate  may be  signed  on behalf of the
Corporation by any person who, at the actual date of the execution of such Right
Certificate,  shall be a proper  officer of the  Corporation  to sign such Right
Certificate,  although at the date of the  execution of this  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 or offices designated as the appropriate place for
surrender  or transfer of such Right  Certificate,  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
certificate number and the date of each of the Right Certificates.

     Section  6.  Transfer,   Split-Up,   Combination   and  Exchange  of  Right
Certificates; Mutilated, Destroyed, Lost or Stelen Right Certificate. Subject to
the provisions of Section 4(b),  Section 7(e) and Section 14 hereof, at any time
after the Close of Business on the Distribution Date, and at or before 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, other securities, as the
case may be) as the Right  Certificate or Right  Certificates  surrendered  then
entitled  such holder (or former  holder in the case of a transfer) to purchase.
Any registered  holder  desiring to transfer,  split up, combine or exchange any
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 or offices of the Rights Agent  designated for such purpose.  Neither the
Rights  Agent  nor  the  Corporation  shall  be  obligated  to take  any  action
whatsoever  with  respect  to  the  transfer  of  any  such  surrendered   Right
Certificate until the registered holder has completed and signed the certificate
contained  in the  form  of  assignment  on  the  reverse  side  of  such  Right
Certificate and shall have provided such additional  evidence of the identity of
the Beneficial Owner (or former  Beneficial  Owner), or Affiliates or Associates
thereof, as the Corporation shall reasonably  request.  Subject to Section 4(b),
Section 7(e) and Section 14 hereof, the Rights Agent shall thereupon countersign
and  deliver  to the  Person  entitled  thereto  a Right  Certificate  or  Right
Certificates,  as the case may be, as so requested.  The Corporation 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.

     Upon receipt by the Corporation 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  Corporation's  request,
reimbursement to the Corporation 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 Corporation will make 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)  hereof,  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
and the  certificate  on the reverse side thereof duly  executed,  to the Rights
Agent at the principal office or offices of the Rights Agent designated for such
purpose,  together  with payment of the aggregate  Purchase  Price for the total
number of one  one-hundredths of a Preferred Share (or other securities,  as the
case may be) as to which such surrendered Rights are exercised, at or before the
earliest  of (i) the  Close  of  Business  on  February  26,  2008  (the  "Final
Expiration Date"), (ii) the date on which the Rights are redeemed as provided in
Section 23 hereof (the "Redemption Date"), or (iii) the date on which the Rights
are exchanged pursuant to Section 24 hereof.

     (b) The  Purchase  Price for each one  one-hundredth  of a Preferred  Share
pursuant  to the  exercise  of a  Right  shall  initially  be  $15,  subject  to
adjustment from time to time as provided in the next sentence and in Sections 11
and 13(a) hereof,  and shall be payable in accordance  with paragraph (c) below.
Notwithstanding anything in this Agreement to the contrary, in the event that at
any time after the date of this Agreement and before the Distribution  Date, the
Corporation  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, each Common Share outstanding following such subdivision, combination
or consolidation  shall continue to have a Right associated  therewith,  and the
Purchase  Price  following any such event shall be  proportionately  adjusted to
equal the result obtained by multiplying the Purchase Price  immediately  before
such event by a fraction  the  numerator  of which shall be the total  number of
Common  Shares   outstanding   immediately  before  the  event  occurs  and  the
denominator  of which  shall be the total  number of Common  Shares  outstanding
immediately  after  such  event  occurs.  The  adjustment  provided  for  in the
preceding  sentence  shall be made  successively  whenever  such a  dividend  is
declared  or  paid  or  such a  subdivision,  combination  or  consolidation  is
effected.

     (c) Upon receiving a Right  Certificate  representing  exercisable  Rights,
with the  form of  election  to  purchase  and the  certificate  duly  executed,
accompanied by payment of the Purchase Price for the Preferred  Shares (or other
securities,  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 6 hereof,  by certified check,  cashier's
check or money order payable to the order of the  Corporation,  the Rights Agent
shall  thereupon  promptly  (i)(A)  requisition  from any transfer  agent of the
Preferred  Shares  certificates  for  the  number  of  Preferred  Shares  to  be
purchased,  and the Corporation hereby irrevocably authorizes its transfer agent
to  comply  with  all  such  requests,  or (B) if the  Corporation,  in its sole
discretion,  shall have elected to deposit the  Preferred  Shares  issuable upon
exercise  of the  Rights  hereunder  into a  depositary,  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 Corporation
will  direct  the  depositary  agent to  comply  with such  requests,  (ii) when
appropriate,  requisition  from the Corporation the amount of cash to be paid in
lieu of issuance of fractional shares, in accordance with Section 14 hereof, and
(iii) after receipt of such certificates or depositary receipts, cause the same,
together with any cash to be paid in lieu of fractional  shares, 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.  In the
event that the  Corporation  is obligated to issue other  securities  (including
Common  Shares)  of the  Corporation  pursuant  to  Section  11(a)  hereof,  the
Corporation will make all  arrangements  necessary so that such other securities
are available for distribution by the Rights Agent, if and when appropriate.

     In addition,  in the case of an exercise of the Rights by a holder pursuant
to  Section  11(a)(ii)  hereof,   the  Rights  Agent  shall  return  such  Right
Certificate  to the  registered  holder  thereof after  imprinting,  stamping or
otherwise   indicating  thereon  that  the  rights  represented  by  such  Right
Certificate  no longer include the rights  provided by Section  11(a)(ii) of the
Rights  Agreement,  and if less than all the  Rights  represented  by such Right
Certificate  were so  exercised,  the Rights  Agent shall  indicate on the Right
Certificate the number of Rights  represented  thereby which continue to include
the rights provided by Section 11(a)(ii).

     (d) In case the registered  holder of any Right  Certificate shall exercise
less than all the Rights evidenced thereby,  a new Right Certificate  evidencing
Rights  equivalent to the Rights  remaining  unexercised  shall be issued by the
Rights Agent to the registered  holder of such Right  Certificate or to his duly
authorized  assigns,  subject to the  provisions  of  Section 14 hereof,  or the
Rights Agent shall place an appropriate  notation on the Right  Certificate with
respect to those Rights exercised.

     (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  Affiliate or Associate of an Acquiring
Person,  (ii) a  transferee  of an  Acquiring  Person  (or of any  Affiliate  or
Associate  thereof) who becomes a transferee  after the Acquiring Person becomes
such,  or (iii) a  transferee  of an  Acquiring  Person (or of any  Affiliate or
Associate  thereof) who becomes a  transferee  before 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 a  continuing  agreement,  arrangement  or  understanding
regarding the transferred  Rights or (B) a transfer which the Board of Directors
of the Corporation,  in its sole  discretion,  has determined is part of a plan,
arrangement  or  understanding  that has as a  primary  purpose  or  effect  the
avoidance  of this  Section  7(e) shall become null and void without any further
action,  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 Corporation 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 Right Certificates or other Person as a
result of its failure to make any  determinations  with  respect to an Acquiring
Person or its Affiliates, Associates or transferees hereunder.

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

     Section 8. Cancellation and Destruction of Rights  Certificates.  All Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination or exchange  shall,  if surrendered to the  Corporation or to any of
its agents,  be delivered to the Rights Agent for  cancellation  or in cancelled
form, or, if  surrendered to the Rights Agent,  shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Agreement. The Corporation 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
Corporation  otherwise  than upon the exercise  thereof.  The Rights Agent shall
deliver all cancelled Right  Certificates to the  Corporation,  or shall, at the
written request of the  Corporation,  destroy such cancelled Right  Certificates
and in such case,  shall deliver a  certificate  of  destruction  thereof to the
Corporation.

     Section  9.   Reservation  and  Availability  of  Preferred   Shares.   The
Corporation  covenants  and agrees that at all times before a Section  11(a)(ii)
Event  occurs  it will  cause  to be  reserved  and  kept  available  out of its
authorized and unissued Preferred Shares, or any authorized and issued Preferred
Shares  held in its  treasury,  the  number  of  Preferred  Shares  that will be
sufficient to permit the exercise in full of all outstanding  Rights and after a
Section 11(a)(ii) Event occurs, shall, to the extent reasonably practicable,  so
reserve and keep  available a sufficient  number of Common Shares  (and/or other
securities)  which may be required to permit the  exercise in full of the Rights
pursuant to this Agreement.

     So long as the  Preferred  Shares  (and,  after a Section  11(a)(ii)  Event
occurs, Common Shares or any other securities) issuable upon the exercise of the
Rights may be listed on any national securities exchange,  the Corporation shall
use its best  efforts to cause,  from and after  such time as the Rights  become
exercisable, all shares reserved for such issuance to be listed on such exchange
upon official notice of issuance upon such exercise.

     The  Corporation  covenants and agrees that it will take all such action as
may be necessary to ensure that all  Preferred  Shares (or Common  Shares and/or
other  securities,  as the case may be) delivered upon exercise of Rights shall,
at the time of delivery of the  certificates for such shares or other securities
(subject to payment of the Purchase Price),  be duly and validly  authorized and
issued and fully paid and non-assessable shares or securities.

     The Corporation  further covenants and agrees that it will pay when due and
payable any and all U.S.  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 (or Common Shares and/or other  securities,  as the case
may be) upon the exercise of Rights.  The  Corporation  shall not,  however,  be
required to pay any transfer tax which may be payable in respect of any transfer
or delivery of Right  Certificates  to a person  other than,  or the issuance or
delivery of  certificates  or depository  receipts for the Preferred  Shares (or
Common Shares and/or other securities,  as the case may be) in a name other than
that of,  the  registered  holder of the  Right  Certificate  evidencing  Rights
surrendered  for  exercise,  or to  issue  or to  deliver  any  certificates  or
depositary  receipts  for  Preferred  Shares  (or  Common  Shares  and/or  other
securities,  as the case may be) 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
Corporation's reasonable satisfaction that no such tax is due.

     The  Corporation  shall  use  its  best  efforts  to (i)  file,  as soon as
practicable  following the Shares  Acquisition  Date, a  registration  statement
under the Act on an appropriate form, with respect to the securities purchasable
upon exercise of the Rights,  (ii) cause such  registration  statement to become
effective  as soon as  practicable  after  such  filing,  and (iii)  cause  such
registration  statement  to remain  effective  (with a  prospectus  at all times
meeting the  requirements of the Act and the rules and  regulations  thereunder)
until the date of the  expiration of the rights  provided by Section  11(a)(ii).
The  Corporation  will also take such action as may be  appropriate  or required
under the blue sky laws of the various states.

     Section 10.  Preferred  Shares  Record Date.  Each person in whose name any
certificate for Preferred Shares (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 Preferred Shares (or
Common Shares and/or other securities, as the case may be) transfer books of the
Corporation  are closed,  such person  shall be deemed to have become the record
holder  of such  shares  on,  and  such  certificate  shall be  dated,  the next
succeeding  Business Day on which the Preferred  Shares (or Common Shares and/or
other  securities,  as the case may be) transfer  books of the  Corporation  are
open.

     Section  11.  Adjustment  of Purchase  Price,  Number and Kind 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  Corporation  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 Corporation is the continuing
     or surviving  corporation),  except as  otherwise  provided in this Section
     11(a) and Section 7(e) hereof,  the Purchase Price in effect at the time of
     the  record  date  for  such  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 before such date
     and at a time when the Preferred  Shares  transfer books of the Corporation
     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  Corporation
     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  before,  any  adjustment  required  pursuant  to Section
     11(a)(ii).

          (ii) In the event any Person,  alone or together  with its  Affiliates
     and Associates,  shall become an Acquiring  Person,  each holder of a Right
     (except as provided below and in Section 7(e) hereof)  shall,  for a period
     of 60 days  after  the  later of the  occurrence  of any such  event or the
     effective  date of an  appropriate  registration  statement  under  the Act
     pursuant  to  Section  9 hereof,  have a right to  receive,  upon  exercise
     thereof at a price equal to the then-current  Purchase Price, in accordance
     with the terms of this Agreement,  such number of Common Shares (or, in the
     discretion  of the Board of  Directors,  one  one-hundredth  of a Preferred
     Share) as shall  equal the  result  obtained  by (x)  multiplying  the then
     current  Purchase  Price  by the then  number  of one  one-hundredths  of a
     Preferred  Share for which a Right was exercisable  immediately  before 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  Corporation's
     Common Shares (determined  pursuant to Section 11(d) hereof) on the date of
     such first  occurrence  (such  number of shares  being  referred  to as the
     "Adjustment Shares"); provided, however, that if the transaction that would
     otherwise  give rise to the  foregoing  adjustment  is also  subject to the
     provisions  of Section 13 hereof,  then only the  provisions  of Section 13
     hereof  shall  apply,  and no  adjustment  shall be made  pursuant  to this
     Section 11(a)(ii);

          (iii) In the event that there shall not be sufficient  treasury shares
     or  authorized  but unissued (and  unreserved)  Common Shares to permit the
     exercise  in  full  of  the  Rights  in   accordance   with  the  foregoing
     subparagraph  (ii) and the Rights become so exercisable  (and the Board has
     determined  to make the Rights  exercisable  into  fractions of a Preferred
     Share),  notwithstanding  any other  provision  of this  Agreement,  to the
     extent  necessary  and  permitted  by  applicable  law,  each  Right  shall
     thereafter  represent the right to receive,  upon  exercise  thereof at the
     then-current Purchase Price in accordance with the terms of this Agreement,
     (x) a number of (or fractions  of) Common Shares (up to the maximum  number
     of Common Shares which may permissibly be issued) and (y) one one-hundredth
     of a  Preferred  Share  or a  number  of,  or  fractions  of  other  equity
     securities  of the  Corporation  (or,  in the  discretion  of the  Board of
     Directors,  debt)  which  the Board of  Directors  of the  Corporation  has
     determined  to have the same  aggregate  current  market value  (determined
     pursuant to Section 11(d)(i) and (ii) hereof, to the extent applicable,) as
     one Common Share (such number of, or fractions of, Preferred Shares,  debt,
     or other equity securities or debt of the Corporation) being referred to as
     a "capital  stock  equivalent"),  equal in the  aggregate  to the number of
     Adjustment Shares;  provided,  however,  if sufficient Common Shares and/or
     capital stock equivalents are unavailable,  then the Corporation  shall, to
     the extent  permitted  by  applicable  law,  take all such action as may be
     necessary  to  authorize   additional   Common   Shares  or  capital  stock
     equivalents  for  issuance  upon  exercise  of the  Rights,  including,  if
     necessary, the calling of a meeting of shareholders; and provided, further,
     that if the Corporation is unable to cause sufficient  Common Shares and/or
     capital  stock  equivalents  to be available  for issuance upon exercise in
     full of the Rights, then each Right shall thereafter represent the right to
     receive  the  Adjusted  Number  of Shares  upon  exercise  at the  Adjusted
     Purchase Price (as such terms are hereinafter defined). As used herein, the
     term  "Adjusted  Number  of  Shares"  shall be equal to that  number of (or
     fractions of) Common Shares (and/or capital stock equivalents) equal to the
     product of (x) the number of  Adjustment  Shares  and (y) a  fraction,  the
     numerator of which is the number of Common  Shares  (and/or  capital  stock
     equivalents)  available  for issuance  upon  exercise of the Rights and the
     denominator of which is the aggregate number of Adjustment Shares otherwise
     issuable  upon  exercise  in  full of all  Rights  (assuming  there  were a
     sufficient number of Common Shares available) (such fraction being referred
     to as the "Proration Factor"). The "Adjusted Purchase Price" shall mean the
     product  of the  Purchase  Price  and the  Proration  Factor.  The Board of
     Directors  may,  but shall not be  required  to,  establish  procedures  to
     allocate the right to receive  Common Shares and capital stock  equivalents
     upon exercise of the Rights among holders of Rights.

     (b) In case the  Corporation  shall fix a record  date for the  issuance of
rights (other than the Rights),  options or warrants to all holders of Preferred
Shares  entitling them (for a period expiring within 45 calendar days after such
record date) to subscribe for or purchase Preferred Shares (or shares having the
same rights,  privileges and  preferences as the Preferred  Shares  ("equivalent
preferred   shares"))  or  securities   convertible  into  Preferred  Shares  or
equivalent  preferred  shares  at a price  per  Preferred  Share  or  equivalent
preferred  share  (or  having  a  conversion  price  per  share,  if a  security
convertible into Preferred Shares or equivalent  preferred shares) less than the
then  current per share  market  price of the  Preferred  Shares (as  determined
pursuant to Section 11(d) hereof) on such record date,  the Purchase Price to be
in effect after such record date shall be determined by multiplying the Purchase
Price in effect immediately before 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  equivalent  preferred  shares so to be
offered  (and/or  the  aggregate  initial  conversion  price of the  convertible
securities  so to be offered)  would  purchase at such  current per share 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  equivalent  preferred  shares to be offered for subscription or purchase
(or into  which  the  convertible  securities  so to be  offered  are  initially
convertible);  provided, however, that in no event shall the consideration to be
paid upon the exercise of one Right be less than the  aggregate par value of the
shares of capital stock of the Corporation  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 Corporation,  whose
determination  shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights Agent.  Preferred Shares owned by or held for the
account of the  Corporation  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  Corporation  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
Corporation  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) hereof),  the Purchase Price to be
in effect after such record date shall be determined by multiplying the Purchase
Price in effect immediately before such record date by a fraction, the numerator
of which  shall be the then  current  per  share  market  price  (as  determined
pursuant to Section 11(d)  hereof) 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  Corporation,  whose  determination  shall be  described  in a
statement  filed with the Rights Agent and shall be binding on the Rights Agent)
of the portion of the 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 Corporation to be issued upon exercise of one
Right. Such adjustments  shall be made successively  whenever such a record date
is fixed;  and in the event that such  distribution is not so made, the Purchase
Price shall again be  adjusted to be the  Purchase  Price which would then be in
effect if such record date had not been fixed.

     (d) (i) For the purpose of any  computation  hereunder,  the  "current  per
share  market  price" of any  security  (a  "Security"  for the  purpose of this
Section  11(d)(i))  on any date  shall be deemed to be the  average of the daily
closing  prices  per share of such  Security  for the  thirty  (30)  consecutive
Trading Days (as such term is hereinafter defined) immediately before 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
before the expiration of thirty (30) Trading Days after the ex-dividend date for
such  dividend  or  distribution,  or the  record  date  for  such  subdivision,
combination  or  reclassification,  then, and in each such case, the current per
share market price shall be appropriately adjusted to reflect the current market
price per share  equivalent  of such  Security.  The closing  price for each day
shall be the last sale price,  regular way, or, in case no such sale takes place
on such day,  the average of the closing bid and asked  prices,  regular way, in
either case as  reported in the  principal  consolidated  transaction  reporting
system with respect to securities  listed or admitted to trading on the 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  Corporation.  If on any
such date no such market maker is making market in the Security,  the fair value
of the  Security  on such  date as  determined  in good  faith  by the  Board of
Directors of the Corporation  shall be used. The term "Trading Day" shall mean a
day on which the principal national securities exchange on which the 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).  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" shall mean the fair value per share as  determined  in good faith by
     the Board of Directors of the  Corporation,  whose  determination  shall be
     described  in a statement  filed with the Rights Agent and shall be binding
     on the Rights Agent.

     (e) Notwithstanding  anything herein to the contrary,  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-hundredth  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
(3) years from the date of the  transaction  which  mandates such  adjustment or
(ii) the Final Expiration Date.

     (f) If as a result of an adjustment  made pursuant to Section  11(a)(ii) or
Section 13(a) hereof, the holder of any Right thereafter  exercised shall become
entitled to receive any shares of capital  stock of the  Corporation  other than
Preferred  Shares,  thereafter  the number of 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  Corporation  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 Corporation shall have exercised its election as provided in
Section 11(i) hereof upon each  adjustment of the Purchase  Price as a result of
the calculations  made in Sections 11(b) and (c) hereof,  each Right outstanding
immediately  before 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-hundredth
of a  Preferred  Share)  obtained  by (i)  multiplying  (x)  the  number  of one
one-hundredths of a share covered by a Right immediately  before this adjustment
by (y) the Purchase Price in effect  immediately  before 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 Corporation may elect on or after the date of any adjustment of the
Purchase Price to adjust the number of Rights,  in lieu of any adjustment in the
number of 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  before  such
adjustment.  Each Right held of record  before 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
before  the  Purchase  Price  is  adjusted  by  the  Purchase  Price  in  effect
immediately  after  such  adjustment.   The  Corporation  shall  make  a  public
announcement  of its  election  to adjust the number of Rights,  indicating  the
record date for the  adjustment,  and,  if known at the time,  the amount of the
adjustment  to be made.  This record date may be the date on which the  Purchase
Price is adjusted or any day  thereafter,  but, if the Right  Certificates  have
been  issued,  shall be at least ten (10) days later than the date of the public
announcement.  If Right  Certificates have been issued,  upon each adjustment of
the number of Rights pursuant to this Section 11(i),  the Corporation  shall, as
promptly as  practicable,  cause to be distributed to holders of record of Right
Certificates  on such  record  date Right  Certificates  evidencing,  subject to
Section 14 hereof, the additional Rights to which such holders shall be entitled
as a result of such  adjustment,  or, at the  option of the  Corporation,  shall
cause  to  be  distributed  to  such  holders  of  record  in  substitution  and
replacement for the Right  Certificates  held by such holders before the date of
adjustment,  and upon surrender  thereof,  if required by the  Corporation,  new
Right  Certificates  evidencing  all the Rights to which such  holders  shall be
entitled after such adjustment. Right Certificates so to be distributed shall be
issued,  executed and  countersigned in the manner provided for herein and shall
be registered in the names of the holders of record of Right Certificates on the
record date specified in the public announcement.

     (j)  Irrespective  of any adjustment or change in the Purchase Price or the
number of one  one-hundredths of a 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  the  then  par  value,  if  any,  of the  number  of one
one-hundredths  of a Preferred Share or other securities  issuable upon exercise
of the Rights, the Corporation shall take any corporate action which may, in the
opinion of its counsel,  be necessary in order that the  Corporation may validly
and   legally   issue  such  number  of  fully  paid  and   non-assessable   one
one-hundredths  of a  Preferred  Share  or  other  securities  at such  adjusted
Purchase Price.

     (l) In any case in which this Section 11 shall  require that an  adjustment
in the  Purchase  Price be made  effective  as of a record  date for a specified
event,  the  Corporation may elect to defer until such event occurs the issuance
to the  holder of any Right  exercised  after  such  record  date the  Preferred
Shares,  Common Shares or other securities of the Corporation,  if any, issuable
upon such exercise over and above the Preferred  Shares,  Common Shares or other
securities of the  Corporation,  if any,  issuable upon exercise on the basis of
the Purchase Price in effect before such adjustment; provided, however, that the
Corporation  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)  Notwithstanding  anything  in this  Section  11 to the  contrary,  the
Corporation  shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments  expressly  required by this Section 11, as and to
the extent that it in its sole  discretion  shall  determine  to be advisable in
order that (i) any  consolidation or subdivision of the Preferred  Shares,  (ii)
issuance  wholly for cash of  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)
stock  dividends or (v) issuance of rights,  options or warrants  referred to in
this Section 11,  hereafter made by the  Corporation to holders of its Preferred
Shares shall not be taxable to such shareholders.

     (n) The  Corporation  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  Corporation  in a transaction  that does not violate  Section
11(n) hereof), (ii) merge with or into any other Person (other than a Subsidiary
of the Corporation in a transaction  that does not violate Section 11(n) 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 Corporation and
its  Subsidiaries  (taken as a whole) to any other Person or Persons (other than
the Corporation  and/or any of its Subsidiaries in one or more transactions each
of which  does  not  violate  Section  11(n)  hereof),  if (x) at the time of or
immediately  after such  consolidation,  merger,  sale or transfer there are any
charter or by-law  provisions or any rights,  warrants or other  instruments  or
securities  outstanding  or agreements in effect or other actions  taken,  which
would  materially  diminish or otherwise  eliminate the benefits  intended to be
afforded by the Rights or (y) before,  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.  The Corporation  shall not
consummate any such consolidation, merger, sale or transfer unless prior thereto
the  Corporation  and such other Person shall have executed and delivered to the
Rights Agent a supplemental  agreement  evidencing  compliance with this Section
11(m).

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

     (p) The exercise of Rights under Section 11(a)(ii) shall only result in the
loss of rights under Section  11(a)(ii) to the extent so exercised and shall not
otherwise  affect the rights  represented  by the Rights  under this  Agreement,
including the rights represented by Section 13 hereof.

     Section 12.  Certificate  of Adjusted  Purchase  Price or Number of Shares.
Whenever an  adjustment  is made as  provided  in Sections 11 or 13 hereof,  the
Corporation  shall  promptly  (a)  prepare  a  certificate  setting  forth  such
adjustment,  and a brief statement of the facts  accounting for such adjustment,
(b) file  with the  Rights  Agent and with each  transfer  agent for the  Common
Shares a copy of such  certificate  and (c) mail a brief summary thereof to each
holder of a Right  Certificate in accordance with Section 26 hereof.  The Rights
Agent shall be fully  protected  in relying on any such  certificate  and on any
adjustment  therein  contained and shall not be deemed to have knowledge of such
adjustment unless and until it shall have received such certificate.

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

     (a) In the  event  that,  on or  following  the  Shares  Acquisition  Date,
directly or indirectly,  (x) the Corporation  shall  consolidate  with, or merge
with and into, any Interested Shareholder or, if in such merger or consolidation
all holders of Common  Shares are not treated  alike any other  Person,  (y) the
Corporation shall  consolidate  with, or merge with, any Interested  Shareholder
or, if in such  merger or  consolidation  all  holders of Common  Shares are not
treated alike, any other Person,  and the Corporation shall be the continuing or
surviving  corporation of such consolidation or merger (other than, in a case of
any transaction  described in (x) or (y), a merger or consolidation  which would
result in all of the  securities  generally  entitled to vote in the election of
directors ("voting securities") of the Corporation outstanding immediately prior
thereto  continuing to represent  (either by remaining  outstanding  or by being
converted into securities of the surviving  entity) all of the voting securities
of the Corporation or such surviving entity  outstanding  immediately after such
merger or consolidation and the holders of such securities not having changed as
a result of such merger or consolidation),  or (z) the Corporation shall sell or
otherwise  transfer (or one or more of its Subsidiaries  shall sell or otherwise
transfer),  in one  transaction or a series of related  transactions,  assets or
earning  power  aggregating  more than 50% of the assets or earning power of the
Corporation  and  its  Subsidiaries   (taken  as  a  whole)  to  any  Interested
Shareholder or  Shareholders  or, if in such  transaction  all holders of Common
Stock are not treated alike, any other Person (other than the Corporation or any
Subsidiary of the Corporation in one or more transactions each of which does not
violate  Section 11(n) hereof),  then, and in each such case (except as provided
in Section 13(d) hereof), proper provision shall be made so that (i) each holder
of a Right, except as provided in Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof at a price equal to the then-current
Purchase  Price,  in accordance  with the terms of this Agreement and in lieu of
Preferred Shares, such number of freely tradeable Common Shares of the Principal
Party (as hereinafter defined), not subject to any liens,  encumbrances,  rights
of first refusal or other adverse claims,  as shall equal the result obtained by
(A)  multiplying  the  then  current   Purchase  Price  by  the  number  of  one
one-hundredths  of a  Preferred  Share  for  which a Right  is then  exercisable
(without taking into account any adjustment  previously made pursuant to Section
11(a)(ii))  and  dividing  that product by (B) 50% of the then-current per share
market price of the Common Shares of such Principal Party  (determined  pursuant
to Section 11(d) hereof) on the date of  consummation  of such Section 13 Event;
(ii) such Principal Party shall  thereafter be liable for, and shall assume,  by
virtue  of  such  Section  13  Event,  all the  obligations  and  duties  of the
Corporation  pursuant  to this  Agreement;  (iii) the term  "Corporation"  shall
thereafter be deemed to refer to such  Principal  Party,  it being  specifically
intended  that the  provisions  of  Section 11 hereof  shall  apply only to such
Principal Party following the first  occurrence of a 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) in connection with the
consummation  of any such  transaction  as may be  necessary  to assure that the
provisions  hereof shall  thereafter be applicable,  as nearly as reasonably may
be, in relation to the Common Shares thereafter deliverable upon the exercise of
the Rights.

     (b) "Principal  Party" shall mean in the case of any transaction  described
in clause (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  Corporation  are
converted in such merger or  consolidation,  and if no securities are so issued,
the Person that is the other party to such merger or  consolidation  (including,
if applicable, the Corporation if it is the surviving corporation);  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 of the foregoing cases, (1) if the
Common Shares of such Person are not at such time and have not been continuously
over the preceding  twelve (12) month period  registered under Section 12 of the
Exchange  Act,  and such  Person is a direct or indirect  Subsidiary  of another
Person the Common  Shares of which are and have been so  registered,  "Principal
Party"  shall  refer  to  such  other  Person;  (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; and (3) in case such Person is owned,  directly
or  indirectly,  by a joint  venture  formed by two or more Persons that are not
owned,  directly or indirectly,  by the same Person,  the rules set forth in (1)
and (2) above shall apply to each of the chains of ownership  having an interest
in such joint  venture as if such  party were a  "Subsidiary"  of both or all of
such joint  venturers,  and the Principal  Parties in each such chain shall bear
the  obligations  set forth in this Section 13 in the same ratio as their direct
or indirect interests in such Person bear to the total of such interests.

     (c) The Corporation  shall not consummate any such  consolidation,  merger,
sale or transfer  unless the Principal  Party shall have a sufficient  number of
its authorized Common Shares which have not been issued or reserved for issuance
to permit the exercise in full of the Rights in accordance with this Section 13,
and unless prior thereto the  Corporation  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  consolidation,
merger,  sale or transfer  mentioned  in  paragraph  (a) of this Section 13, the
Principal Party at its own expense shall:

          (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 Final Expiration Date;

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

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

     The  provisions  of this  Section 13 shall  similarly  apply to  successive
mergers or  consolidations  or sales or other  transfers.  The rights under this
Section 13 shall be in addition to the rights to exercise Rights and adjustments
under Section 11(a)(ii) and shall survive any exercise thereof.

     (d)  Notwithstanding  anything  in this  Agreement  to the  contrary,  this
Section 13 shall not be applicable to a transaction  described in  subparagraphs
(x) and (y) of Section  13(a) if: (i) such  transaction  is  consummated  with a
Person or Persons who acquired 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 Permitted  Offer;  and (iii) the form of  consideration  offered in such
transaction  is the  same as the form of  consideration  paid  pursuant  to such
Permitted Offer. Upon consummation of any such transaction  contemplated by this
Section 13(d), all Rights hereunder shall expire.

     Section 14. Fractional Rights and Fractional Shares.

     (a) The  Corporation  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  before 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 Corporation. 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 Corporation shall be used.

     (b) The  Corporation  shall not be required to issue fractions of Preferred
Shares (other than fractions which are one  one-hundredth or 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 one one-hundredth or 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 Corporation,
be  evidenced  by  depositary  receipts,  pursuant to an  appropriate  agreement
between the  Corporation  and a depositary  selected by it;  provided  that such
agreement shall provide that the holders of such depositary  receipts shall have
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 one  one-hundredth  or  integral
multiples of one  one-hundredth of a Preferred Share, the Corporation  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)(ii)  hereof) for
the Trading Day immediately before the date of such exercise.

     (c) Following the occurrence of one of the transactions or events specified
in Section 11 giving rise to the right to receive Common  Shares,  capital stock
equivalents  (other than Preferred Shares) or other securities upon the exercise
of a Right,  the Corporation  shall not be required to issue fractions of shares
or units of such Common Shares,  capital stock  equivalents or other  securities
upon  exercise  of the  Rights  or to  distribute  certificates  which  evidence
fractions of such Common Shares,  capital stock equivalents or other securities.
In lieu of  fractional  shares or units of such  Common  Shares,  capital  stock
equivalents  or other  securities,  the  Corporation  may pay to the  registered
holders of Right  Certificates  at the time such Rights are  exercised as herein
provided  an amount in cash equal to the same  fraction  of the  current  market
value of a share or unit of such Common  Shares,  capital stock  equivalents  or
other  securities.  For purposes of this Section 14(c), the current market value
shall be  determined  in the manner set forth in  Section  11(d)  hereof for the
Trading Day  immediately  before the date of such  exercise and, if such capital
stock  equivalent is not traded,  each such capital stock  equivalent shall have
the value of one one-hundredth of a Preferred Share.

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

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

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

     (a) before 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 or offices of the Rights Agent designated for such purpose, duly endorsed
or accompanied by a proper  instrument of transfer and with the appropriate form
fully executed;

     (c) subject to Section 6 and Section 7(f) hereof,  the  Corporation and the
Rights  Agent may deem and treat the person in whose name the Right  Certificate
(or, before 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 Certificate
or the  associated  Common  Shares  certificate  made by anyone  other  than the
Corporation  or the Rights Agent) for all purposes  whatsoever,  and neither the
Corporation  nor the Rights Agent,  subject to the last sentence of Section 7(e)
hereof, shall be required to be affected by any notice to the contrary; and

     (d) notwithstanding anything in this Agreement to the contrary, neither the
Corporation  nor the Rights  Agent shall have any  liability  to any holder of a
Right or a  beneficial  interest  in 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  Corporation  must use its best  efforts  to have any such  order,
decree or ruling lifted or otherwise overturned as soon as possible.

     Section 17. Right Certificate  Holder Not Deemed a 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  Common  Shares or any other
securities of the Corporation  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  Corporation 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 hereof), or to receive dividends
or other distributions or to exercise any preemptive or subscription  rights, or
otherwise,  until the Right or Rights evidenced by such Right  Certificate shall
have been exercised in accordance with the provisions hereof.

     Section 18.  Concerning the Rights Agent. The Corporation  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 Corporation 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. The indemnity provided
for herein shall  survive the  expiration of the Rights and the  termination  of
this Agreement.

     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  Common  Shares or for  other  securities  of the  Corporation,
instrument of assignment or transfer, power of attorney, endorsement, affidavit,
letter, notice, direction,  consent,  certificate,  statement, or other paper or
document  believed by it to be genuine  and to be signed,  executed  and,  where
necessary, verified or acknowledged, by the proper Person or Persons.

     Section 19. Merger or  Consolidation or Change of Name of Rights Agent. 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
all or substantially  all of the 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 hereto,  provided that such corporation  would
be eligible for appointment as a successor  Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this  Agreement,  any of the Right  Certificates  shall
have been  countersigned but not delivered,  any such successor Rights Agent may
adopt the  countersignature of a 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 or in
the name of the  successor  Rights  Agent;  and in all  such  cases  such  Right
Certificates shall have the full force provided in the Right Certificates and in
this Agreement.

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

     Section 20. Duties of Rights Agent.  The Rights Agent undertakes only those
duties and  obligations  imposed by this Agreement upon the following  terms and
conditions,   by  all  of  which  the  Corporation  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 Corporation),  and the opinion of such counsel shall be full and
complete authorization and protection to the Rights Agent as to any action taken
or omitted by it in good faith and in accordance with such opinion.

     (b)  Whenever in the  performance  of its duties under this  Agreement  the
Rights  Agent  shall  deem it  necessary  or  desirable  that any fact or matter
(including,  without  limitation,  the identity of an  Acquiring  Person and the
determination  of the  current  market  price  of any  Security)  be  proved  or
established by the Corporation  before 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 Chief
Executive  Officer,  the  President,  any Vice  President,  the Treasurer or the
Secretary  of the  Corporation  and  delivered  to the  Rights  Agent;  and such
certificate shall be full authorization to the Rights Agent for any action taken
or  suffered  in good  faith by it under the  provisions  of this  Agreement  in
reliance upon such certificate.

     (c) The Rights Agent shall be liable hereunder only for its own 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  on such Right  Certificates)  or be
required to verify the same, but all such  statements and recitals are and shall
be deemed to have been made by the Corporation only.

     (e) The Rights  Agent shall not be under any  responsibility  in respect of
the validity of this Agreement or the execution and delivery  hereof (except the
due  execution  hereof by the Rights  Agent) or in respect  of the  validity  or
execution of any Right Certificate (except its  countersignature  thereof),  nor
shall it be  responsible  for any breach by the  Corporation  of any covenant or
condition contained in this Agreement or in any Rights Certificate; nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 7(e) hereof) or any adjustment required
under the provisions of Section 11 or Section 13 hereof or  responsible  for the
manner,  method or  amount of any such  adjustment  or the  ascertaining  of the
existence of facts that would require any such  adjustment  (except with respect
to the exercise of Rights evidenced by Right  Certificates  after receipt of the
certificate  described in Section 12 hereof);  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 or Common Shares to be issued  pursuant to
this Agreement or any Right Certificate or as to whether any Preferred Shares or
Common Shares will, when issued,  be validly  authorized and issued,  fully paid
and non-assessable.

     (f) The Corporation 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 Chief Executive  Officer,  the President,
any Vice President,  the Treasurer or the Secretary of the  Corporation,  and to
apply to such officers for advice or instructions in connection with its duties,
and shall not be liable for any action  taken or suffered by it in good faith or
lack of action in accordance  with  instructions  of any such officer or for any
delay in acting while waiting for those  instructions.  Any  application  by the
Rights Agent for written instructions from the Corporation may, at the option of
the Rights  Agent,  set forth in  writing  any  action  proposed  to be taken or
omitted by the Rights Agent under this  Agreement and the date on or after which
such action shall be taken or such omission shall be effective. The Rights Agent
shall not be liable for any action taken by, or omission of, the Rights Agent in
accordance with a proposal included in any such application on or after the date
specified in such  application  (which date shall not be less than five Business
Days  after the date any  officer  of the  Corporation  actually  receives  such
application,  unless  any such  officer  shall have  consented  in writing to an
earlier  date) unless,  before taking any such action (or the effective  date in
the  case  of an  omission),  the  Rights  Agent  shall  have  received  written
instruction in response to such application specifying the action to be taken or
omitted.

     (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 Corporation or become pecuniarily  interested in any transaction in which
the  Corporation  may be  interested,  or  contract  with or lend  money  to the
Corporation  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 Corporation 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 Corporation  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 Rights  Certificate  surrendered  to the Rights
Agent  for  exercise  or  transfer,  the  certificate  attached  to the  form of
assignment  or form of  election to  purchase,  as the case may be, has not been
completed,  the Rights  Agent shall not take any further  action with respect to
such  requested   exercise  of  transfer   without  first  consulting  with  the
Corporation.

     Section  21.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon thirty (30) days' notice in writing mailed to the  Corporation  and to each
transfer  agent of the  Common  Shares  or  Preferred  Shares by  registered  or
certified  mail,  and to the holders of the Right  Certificates  by  first-class
mail. The Corporation may remove the Rights Agent or any successor  Rights Agent
upon sixty (60) days' notice in writing, mailed to the Rights Agent or successor
Rights  Agent,  as the case may be,  and to each  transfer  agent of the  Common
Shares or Preferred  Shares by registered or certified  mail,  and to 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 Corporation shall
appoint a successor to the Rights Agent. If the  Corporation  shall fail to make
such appointment  within a period of sixty (60) days after giving notice of such
removal  or  after  it has been  notified  in  writing  of such  resignation  or
incapacity by the resigning or incapacitated  Rights Agent or by the holder of a
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection  by the  Corporation),  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
Corporation  or by such a court,  shall be a  corporation  organized  and  doing
business  under the laws of the United  States or any state of the United States
in good  standing,  which is  authorized  under such laws to exercise  corporate
trust or stock  transfer  powers and is subject to supervision or examination by
federal  or state  authority  and  which has at the time of its  appointment  as
Rights  Agent a combined  capital  and  surplus of at least $10  million.  After
appointment,  the  successor  Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent  without  further  act or deed;  but the  predecessor  Rights  Agent shall
deliver and transfer to the successor Rights Agent any property at the time held
by it hereunder, and execute and deliver any further assurance,  conveyance, act
or deed necessary for the purpose. Not later than the effective date of any such
appointment  the  Corporation  shall file  notice  thereof  in writing  with the
predecessor  Rights  Agent  and each  transfer  agent of the  Common  Shares  or
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.

     Section 22. Issuance of New Right Certificates.  Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary,  the  Corporation
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 before the earlier of the Redemption  Date
and the Final  Expiration Date, the Corporation (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,  or upon the exercise,  conversion or exchange of
securities,  notes or debentures issued by the Corporation,  and (b) may, in any
other case, if deemed  necessary or appropriate by the Board of Directors of the
Corporation,  issue Right  Certificates  representing the appropriate  number of
Rights in connection with such issuance or sale; provided, however, that (i) the
Corporation shall not be obligated to issue any such Right  Certificates if, and
to the extent  that,  the  Corporation  shall be  advised  by counsel  that such
issuance would create a significant risk of material adverse tax consequences to
the  Corporation or the Person to whom such Right  Certificate  would be issued,
and (ii) no Right  Certificate  shall be  issued  if,  and to the  extent  that,
appropriate  adjustment  shall  otherwise have been made in lieu of the issuance
thereof.

     Section 23. Redemption and Termination.

     (a)      (i) The Board of Directors of the Corporation  may, at its option,
     redeem  all  but not  less  than  all  the  then  outstanding  Rights  at a
     redemption  price of $.0001 per Right, as such amount may be  appropriately
     adjusted to reflect any stock split, stock dividend or similar  transaction
     occurring after the date hereof (such  redemption  price being  hereinafter
     referred to as the "Redemption  Price"),  at any time before the earlier of
     (x)  the  occurrence  of a  Section  11(a)(ii)  Event,  or  (y)  the  Final
     Expiration  Date. The  Corporation  may, at its option,  pay the Redemption
     Price  either in Common  Shares  (based on the  "current  per share  market
     price," as defined in Section  11(d)  hereof,  of the Common  Shares at the
     time of redemption) or cash; provided that if the Corporation elects to pay
     the  Redemption  Price in  Common  Shares,  the  Corporation  shall  not be
     required  to issue any  fractional  Common  Shares and the number of Common
     Shares  issuable to each holder of Rights shall be rounded down to the next
     whole share.

          (ii) In addition,  the Board of Directors of the  Corporation  may, at
     its option,  at any time  following the  occurrence of a Section  11(a)(ii)
     Event and the  expiration  of any period  during which the holder of Rights
     may exercise the rights under  Section  11(a)(ii) but before any Section 13
     Event,  redeem all but not less than all of the then outstanding  Rights at
     the Redemption  Price (x) in connection with any merger,  consolidation  or
     sale or  other  transfer  (in one  transaction  or in a series  of  related
     transactions)  of assets or earning  power  aggregating  50% or more of the
     earning power of the Corporation and its subsidiaries (taken as a whole) in
     which all  holders of Common  Shares are  treated  alike and not  involving
     (other than as a holder of Common  Shares being treated like all other such
     holders)  an  Interested  Shareholder  or (y)(aa) if and for so long as the
     Acquiring  Person  is not  thereafter  the  Beneficial  Owner of 20% of the
     Common  Shares,  and (bb) at the time of  redemption  no other  Persons are
     Acquiring Persons.

     (b)  In  the  case  of  a  redemption  permitted  under  Section  23(a)(i),
immediately  upon the date for redemption set forth (or determined in the manner
specified  in) in a  resolution  of the Board of  Directors  of the  Corporation
ordering the  redemption of the Rights,  evidence of which shall have been filed
with the Rights  Agent,  and without any further  action and without any notice,
the right to exercise the Rights will terminate,  and the only right  thereafter
of the holders of Rights shall be to receive the Redemption Price for each Right
so held. In the case of a redemption  permitted  only under  Section  23(a)(ii),
evidence  of which  shall have been filed  with the Rights  Agent,  the right to
exercise the Rights will  terminate and represent  only the right to receive the
Redemption  Price upon the later of ten (10) Business Days  following the giving
of such notice or the  expiration  of any period  during  which the rights under
Section  11(a)(ii) may be exercised.  The Corporation shall promptly give public
notice of any such redemption;  provided,  however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within ten (10) days after such date for redemption set forth in a resolution of
the Board of Directors  ordering the redemption of the Rights,  the  Corporation
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,  before 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 Corporation 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 and other  than in  connection  with the  purchase  of Common  Shares
before the Distribution Date.

     (c) The  Corporation  may, at its option,  discharge all of its obligations
with respect to the Rights by (i) issuing a press release  announcing the manner
of redemption of the Rights in accordance  with this  Agreement and (ii) mailing
payment of the Redemption Price to the registered holders of the Rights at their
last  addresses  as they appear on the  registry  books of the Rights  Agent or,
before the Distribution Date, on the registry books of the Transfer Agent of the
Common  Shares,   and  upon  such  action,  all  outstanding  Rights  and  Right
Certificates  shall  be  null  and  void  without  any  further  action  by  the
Corporation.

     Section 24. Exchange.

     (a) The Board of Directors of the  Corporation  may, at its option,  at any
time after any Person becomes an Acquiring  Person,  exchange all or part of the
then  outstanding  and  exercisable  Rights (which shall not include Rights that
have become void  pursuant to the  provisions of Section  11(a)(ii)  hereof) for
Common Shares of the  Corporation  at an exchange  ratio of one Common Share per
Right,  appropriately  adjusted to reflect any stock  split,  stock  dividend or
similar  transaction  occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors  shall not be  empowered  to effect such  exchange at any
time  after any  Person  (other  than the  Corporation,  any  Subsidiary  of the
Corporation,  the Ventek Officers,  any employee benefit plan of the Corporation
or any such Subsidiary,  any entity holding Common Shares for or pursuant to the
terms of any such a plan),  together with all  Affiliates and Associates of such
Person,  becomes the  Beneficial  Owner of 50% or more of the Common Shares then
outstanding.

     (b)  Immediately  upon  the  action  of  the  Board  of  Directors  of  the
Corporation  ordering the exchange of any Rights  pursuant to subsection  (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  Corporation  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 Corporation shall promptly mail a
notice of any such  exchange  to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given,  whether or
not the holder receives the notice.  Each such notice of exchange will state the
method by which the  exchange  of the Common  Shares for Rights will be effected
and, in the event of any partial  exchange,  the number of Rights  which will be
exchanged.  Any partial  exchange shall be effected pro rata based on the number
of Rights (other than Rights which have become void  pursuant to the  provisions
of Section 11(a)(ii) hereof) held by each holder of Rights.

     (c) In any exchange  pursuant to this Section 24, the  Corporation,  at its
option, may substitute Preferred Shares (or equivalent preferred shares, as such
term is defined in Section  11(b)  hereof) for some or all of the Common  Shares
exchangeable for Rights, at the initial rate of one one-hundredth of a Preferred
Share (or equivalent  preferred  share) for each Common Share, as  appropriately
adjusted to reflect  adjustments  in the voting rights of the  Preferred  Shares
pursuant  to the  terms  thereof,  so that the  fraction  of a  Preferred  Share
delivered in lieu of each Common Share shall have the same voting  rights as one
Common Share.

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

     Section 25. Notice of Certain Events.

     (a) In case the Corporation  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
regularly  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 any other Person (other than a Subsidiary of the  Corporation  in a
transaction which does not violate Section 11(n) hereof), 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  Corporation  and its  Subsidiaries  (taken as a
whole) to any other Person or Persons (other than the Corporation  and/or any of
its  Subsidiaries  in one or more  transactions  each of which does not  violate
Section 11(n) hereof), or (v) to effect the liquidation,  dissolution or winding
up of the  Corporation,  then, in each such case, the Corporation  shall give to
each holder of a Right  Certificate,  in  accordance  with Section 26 hereof,  a
notice of such  proposed  action to the extent  feasible and file a  certificate
with the Rights  Agent to that effect,  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 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) above at least  twenty (20) days before 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  twenty  (20) days
before  the  date  of  the  taking  of  such  proposed  action  or the  date  of
participation therein by the holders of the Preferred Shares, whichever shall be
the earlier.

     (b) In case of a Section 11(a)(ii) Event, then (i) the Corporation shall as
soon as practicable  thereafter give to each holder of a Right  Certificate,  in
accordance  with Section 26 hereof,  a notice of the  occurrence  of such event,
which notice shall  describe  such event and the  consequences  of such event to
holders of Rights under Section 11(a)(ii) hereof, and (ii) all references in the
preceding  paragraph (a) to Preferred Shares shall be deemed thereafter to refer
also  to  Common  Shares  and/or,  if  appropriate,   other  securities  of  the
Corporation.

     Section 26. Notices.  Notices or demands authorized by this Agreement to be
given or made by the Rights Agent or by the holder of any Right  Certificate  to

prepaid,  addressed to such holder at the address of such holder as shown on the
registry books of the Corporation.

     Section 27.  Supplements and Amendments.  Before the Distribution Date, the
Corporation  and  the  Rights  Agent  shall,  if  the  Corporation  so  directs,
supplement or amend any provision of this Agreement  without the approval of any
holders  of  certificates   representing  Common  Shares.  From  and  after  the
Distribution   Date,  the  Corporation  and  the  Rights  Agent  shall,  if  the
Corporation so directs,  supplement or amend this Agreement without the approval
of any holders of Right Certificates in order (i) to cure any ambiguity, (ii) to
correct or supplement any provision  contained  herein which may be defective or
inconsistent with any other provisions herein,  (iii) to shorten or lengthen any
time period  hereunder or (iv) to change or supplement the provisions  hereunder
in any manner which the  Corporation  may deem  necessary or desirable and which
shall not adversely  affect the  interests of the holders of Right  Certificates
(other than an  Acquiring  Person or an  Affiliate  or Associate of an Acquiring
Person);  provided,  however,  that this  Agreement may not be  supplemented  or
amended to  lengthen,  pursuant  to clause  (iii) of this  sentence,  (A) a time
period  relating  to when the Rights may be  redeemed at such time as the Rights
are not then redeemable, or (B) any other time period unless such lengthening is
for the purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights.  Upon the delivery of a certificate  from an
appropriate officer of the Corporation which states that the proposed supplement
or  amendment  is in  compliance  with the terms of this  Section 27, the Rights
Agent shall execute such supplement or amendment,  provided that such supplement
or amendment  does not adversely  affect the rights or obligations of the Rights
Agent under Section 18 or Section 20 of this Agreement.  Before the Distribution
Date, the interests of the holders of Rights shall be deemed coincident with the
interests of the holders of Common Shares.

     Section 28.  Determination and Actions by the Board of Directors,  etc. The
Board of  Directors  of the  Corporation  shall  have the  exclusive  power  and
authority to  administer  this  Agreement  and to exercise all rights and powers
specifically granted to the Board, or the Corporation, or as may be necessary or
advisable  in  the   administration  of  this  Agreement,   including,   without
limitation,  the  right  and  power  to (i)  interpret  the  provisions  of this
Agreement,  and (ii) make all  determinations  deemed necessary or advisable for
the  administration  of  this  Agreement  (including,   without  limitation,   a
determination  to redeem or not redeem the Rights or to amend the  Agreement and
whether any proposed amendment adversely affects the interests of the holders of
Right Certificates).  For all purposes of this Agreement, any calculation of the
number of Common Shares or other securities  outstanding at any particular time,
including  for  purposes  of  determining  the  particular  percentage  of  such
outstanding  Common  Shares or any other  securities  of which any Person is the
Beneficial  Owner,  shall be made in  accordance  with the last sentence of Rule
13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act as in
effect  on  the  date  of  this  Agreement.  All  such  actions,   calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith,  shall (x) be final,  conclusive and binding on the  Corporation,
the Rights Agent,  the holders of the Right  Certificates and all other parties,
and (y) not  subject  the Board to any  liability  to the  holders  of the Right
Certificates.

     Section 29. Successors.  All the covenants and provisions of this Agreement
by or for the  benefit of the  Corporation  or the Rights  Agent  shall bind and
inure to the benefit of their respective successors and assigns hereunder.

     Section 30. Benefits of This Agreement.  Nothing in this Agreement shall be
construed to give to any person or corporation  other than the Corporation,  the
Rights Agent and the registered  holders of the Right  Certificates (and, before
the Distribution  Date, the Common Shares) any legal or equitable right,  remedy
or claim  under this  Agreement;  but this  Agreement  shall be for the sole and
exclusive  benefit  of the  Corporation,  the  Rights  Agent and the  registered
holders of the Right Certificates (and, before the Distribution Date, the Common
Shares).

     Section 31. Severability.  If any term, provision,  covenant or restriction
of this  Agreement  is  held  by a court  of  competent  jurisdiction  or  other
authority  to be invalid,  void or  unenforceable,  the  remainder of the terms,
provisions,  covenants and  restrictions  of this Agreement shall remain in full
force and effect and shall in no way be affected, impaired or invalidated.

     Section   Governing  Law.  This  Agreement,   each  Right  and  each  Right

                          CERTIFICATE OF DETERMINATION

                                       OF

                       ADVANCED MACHINE VISION CORPORATION


     William J. Young and Alan R. Steel hereby certify that:

     1. They are the duly  elected  and  acting  President  and Chief  Financial
Officer,  respectively,  of Advanced  Machine Vision  Corporation,  a California
corporation (the "Corporation").

     2. The authorized number of shares of Preferred Stock of the Corporation is
5,000,000, none of which has been issued.

     3. The Board of Directors of the Corporation has duly adopted the following
recitals and resolutions.

     WHEREAS,  the Articles of  Incorporation  of the Corporation  authorize the
Preferred  Stock of the  Corporation  to be issued in series and  authorize  the
Board of Directors of the  Corporation  to  determine  the rights,  preferences,
privileges  and  restrictions  granted  to or imposed  upon any wholly  unissued
series of Preferred Stock and to fix the number of shares and designation of any
such series; and

     WHEREAS, the Board of Directors of the Corporation desires, pursuant to its
authority as aforesaid, to determine and fix the rights, preferences, privileges
and restrictions relating to a series of Series A Junior Participating Preferred
Stock and the number of shares constituting and the designation of said series;

     NOW,  THEREFORE,  BE IT RESOLVED,  that the Board of Directors hereby fixes
and determines the  designation of, the number of shares  constituting,  and the
rights,  preferences,  privileges and  restrictions  relating to, said series of
Series A Junior Participating Preferred Stock as follows:

     Series A Junior Participating Preferred Stock.

     Section 1.  Designation,  Par Value and  Amount.  The shares of such series
shall  be  designated  as  "Series  A  Junior  Participating   Preferred  Stock"
(hereinafter  referred  to as "Series A  Preferred  Stock"),  the shares of such
series  shall be without  par value and the number of shares  constituting  such
series  shall be  400,000;  provided,  however,  that,  if more  than a total of
400,000  shares of Series A Preferred  Stock shall be issuable upon the exercise
of Rights (the "Rights")  issued pursuant to the Rights  Agreement,  dated as of
February 27, 1998,  between the  Corporation and American Stock Transfer & Trust
Company,   as  Rights  Agent  (as  amended  from  time  to  time)  (the  "Rights
Agreement"), the Board of Directors of the Corporation,  pursuant to Section 401
of the  California  General  Corporation  Law,  shall  direct by  resolution  or
resolutions  that a certificate  be property  executed,  acknowledged  and filed
providing for the total number of shares of Series A Preferred Stock  authorized
to  be  issued  to  be  increased  (to  the  extent  that  the   Certificate  of
Incorporation then permits) to the largest number of whole shares (rounded up to
the nearest whole number) issuable upon exercise of the Rights.

     Section 2. Dividends and Distributions.

     (a) Subject to the prior and  superior  rights of the holders of any shares
of any series of  Preferred  Stock  ranking  prior and superior to the shares of
Series A Preferred  Stock with  respect to  dividends,  the holders of shares of
Series A Preferred Stock shall be entitled to receive,  when, as and if declared
by the Board of  Directors  out of assets  legally  available  for the  purpose,
quarterly  dividends  payable  in cash on the first  business  day of  November,
February,  May and August 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 Series A  Preferred  Stock,  in an amount per share  (rounded  to the nearest
cent)  equal to the  greater of (a) $1.00 or (b)  subject to the  provision  for
adjustment  hereinafter  set forth,  100 times the aggregate per share amount of
all cash  dividends,  and 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 Class A Common Stock,  without par value, of the  Corporation  (the
"Common Stock") or a subdivision of the  outstanding  shares of Common Stock (by
reclassification  or  otherwise),   declared  on  the  Common  Stock  since  the
immediately  preceding  Quarterly Dividend Payment Date, or, with respect to the
first Quarterly  Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock.

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

     (c) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A  Preferred  Stock  from the  Quarterly  Dividend  Payment  Date next
preceding the date of issue of such shares of Series A Preferred  Stock,  unless
the date of  issue of such  shares  is  before  the  record  date for the  first
Quarterly  Dividend  Payment Date, in which case  dividends on such shares shall
begin to accrue  from the date of issue of such  shares,  or unless  the date of
issue is a Quarterly  Dividend  Payment  Date or is a date after the record date
for the  determination of holders of shares of Series A Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date,
in either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly  Dividend  Payment Date.  Accrued but unpaid dividends shall
not bear interest.  Dividends paid on the shares of Series A Preferred  Stock in
an amount less than the total  amount of such  dividends at the time accrued and
payable on such shares shall be  allocated  pro rata on a  share-by-share  basis
among all such shares at the time outstanding.  The Board of Directors may fix a
record  date for the  determination  of holders of shares of Series A  Preferred
Stock  entitled  to  receive  payment  of a dividend  or  distribution  declared
thereon,  which record date shall be not more than 60 days before the date fixed
for the payment thereof.

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

     (a) Except as provided in  paragraph C of this Section 3 and subject to the
provision for adjustment hereinafter set forth, each share of Series A Preferred
Stock shall entitle the holder thereof to 100 votes on all matters  submitted to
a vote of the shareholders of the Corporation.

     (b) Except as otherwise provided herein or by law, the holders of shares of
Series A Preferred  Stock and the  holders of shares of Common  Stock shall vote
together as one class on all matters  submitted to a vote of shareholders of the
Corporation.

     (c)      (i) If, on the date used to determine  shareholders  of record for
     any meeting of  shareholders  for the election of  directors,  a default in
     preference dividends (as defined in subparagraph (v) below) on the Series A
     Preferred  Stock shall exist,  the holders of the Series A Preferred  Stock
     shall have the right,  voting as a class as described in subparagraph  (ii)
     below,  to elect two  directors  (in addition to the  directors  elected by
     holders of Common  Stock of the  Corporation).  Such right may be exercised
     (a) at any meeting of shareholders  for the election of directors or (b) at
     a  meeting  of  the  holders  of  shares  of  Voting  Preferred  Stock  (as
     hereinafter defined), called for the purpose in accordance with the By-laws
     of the Corporation, until all such cumulative dividends (referred to above)
     shall  have been paid in full or until  noncumulative  dividends  have been
     paid regularly for at least one year.

          (ii) The right of the holders of Series A Preferred Stock to elect two
     directors,  as described above,  shall be exercised as a class concurrently
     with the  rights of  holders of any other  series of  Preferred  Stock upon
     which voting  rights to elect such  directors  have been  conferred and are
     then exercisable. The Series A Preferred Stock and any additional series of
     Preferred  Stock which the  Corporation may issue and which may provide for
     the  right  to vote  with the  foregoing  series  of  Preferred  Stock  are
     collectively referred to herein as "Voting Preferred Stock."

          (iii)  Each  director  elected  by the  holders  of  shares  of Voting
     Preferred  Stock shall be referred to herein as a  "Preferred  Director." A
     Preferred  Director so elected shall continue to serve as such director for
     a term of one year, except that upon any termination of the right of all of
     such holders to vote as a class for Preferred Directors, the term of office
     of such directors shall  terminate.  Any Preferred  Director may be removed
     by, and shall not be removed  except by, the vote of the  holders of record
     of a majority  of the  outstanding  shares of Voting  Preferred  Stock then
     entitled to vote for the  election of  directors,  present (in person or by
     proxy)  and  voting  together  as a single  class (a) at a  meeting  of the
     shareholders,  or (b) at a meeting of the  holders of shares of such Voting
     Preferred  Stock,  called for the purpose in accordance with the By-laws of
     the  Corporation,  or (c) by  written  consent  signed by the  holders of a
     majority  of the then  outstanding  shares of Voting  Preferred  Stock then
     entitled to vote for the election of directors,  taken together as a single
     class.

          (iv) So long as a default in any preference  dividends on the Series A
     Preferred  Stock shall  exist or the holders of any other  series of Voting
     Preferred  Stock shall be entitled to elect  Preferred  Directors,  (a) any
     vacancy  in the office of a  Preferred  Director  may be filled  (except as
     provided in the following clause (b)) by an instrument in writing signed by
     the remaining  Preferred Director and filed with the Corporation and (b) in
     the case of the  removal of any  Preferred  Director,  the  vacancy  may be
     filled by the vote or written  consent of the  holders of a majority of the
     outstanding  shares of Voting Preferred Stock then entitled to vote for the
     election of directors,  present (in person or by proxy) and voting together
     as a single  class,  at such time as the removal  shall be  effected.  Each
     director  appointed as aforesaid by the remaining  Preferred Director shall
     be deemed,  for all purposes hereof, to be a Preferred  Director.  Whenever
     (x) no default in  preference  dividends  on the Series A  Preferred  Stock
     shall exist and (y) the holders of other series of Voting  Preferred  Stock
     shall no longer be entitled  to elect such  Preferred  Directors,  then the
     number of directors  constituting the Board of Directors of the Corporation
     shall be reduced by two.

          (v) For purposes  hereof,  a "default in preference  dividends" on the
     Series A Preferred  Stock  shall be deemed to have  occurred  whenever  the
     amount of cumulative and unpaid  dividends on the Series A Preferred  Stock
     shall be equivalent to six full quarterly dividends or more (whether or not
     consecutive),  and,  having so occurred,  such  default  shall be deemed to
     exist thereafter  until,  but only until,  all cumulative  dividends on all
     shares of the Series A  Preferred  Stock then  outstanding  shall have been
     paid through the last Quarterly  Dividend  Payment Date or until,  but only
     until,  non-cumulative  dividends have been paid regularly for at least one
     year.

     (d) Except as set forth  herein (or as  otherwise  required  by  applicable
law),  holders  of Series A  Preferred  Stock  shall  have no general or special
voting  rights and their  consent shall not be required for taking any corporate
action.

     Section 4. Certain Restrictions.

     (a)  Whenever  quarterly  dividends  or other  dividends  or  distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared,  on shares of Series A Preferred Stock  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 Series A Preferred Stock;

          (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 Series A Preferred Stock,
     except  dividends paid ratably on the Series A Preferred Stock and all such
     parity stock on which  dividends are payable or in arrears in proportion to
     the  total  amounts  to  which  the  holders  of all such  shares  are then
     entitled;

          (iii)  redeem or  purchase  or  otherwise  acquire  for  consideration
     (except as  provided  in (iv)  below)  shares of any stock  ranking  junior
     (either as to dividends or upon liquidation,  dissolution or winding up) to
     the Series A Preferred Stock, provided 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
     Series A Preferred Stock;

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

     (b) The  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  shares of Series A  Preferred  Stock
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall be retired and cancelled 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,  in any other  Certificate  of Amendment  creating a
series of Preferred Stock or as otherwise required by law.

     Section 6. Liquidation, Dissolution or Winding Up.

     (a)  Subject to the prior and  superior  rights of holders of any shares of
any series of Preferred Stock ranking prior and superior to the shares of Series
A  Preferred  Stock with  respect to rights  upon  liquidation,  dissolution  or
winding  up  (voluntary  or  otherwise),  no  distribution  shall be made to the
holders  of shares of stock  ranking  junior  (either  as to  dividends  or upon
liquidation,  dissolution or winding up) to the Series A Preferred Stock unless,
prior  thereto,  the  holders of shares of Series A  Preferred  Stock shall have
received  $100 per share,  plus an amount equal to accrued and unpaid  dividends
and distributions thereon,  whether or not declared, to the date of such payment
(the "Series Liquidation Preference").  Following the payment of the full amount
of the Series A Liquidation  Preference,  no additional  distributions  shall be
made to the holders of shares of Series A Preferred Stock unless, prior thereto,
the holders of shares of Common  Stock  shall have  received an amount per share
(the "Capital  Adjustment")  equal to the quotient  obtained by dividing (i) the
Series A  Liquidation  Preference  by (ii) 100 (such number in clause (ii),  the
"Adjustment  Number").  Following the payment of the full amount of the Series A
Liquidation  Preference and the Capital Adjustment in respect of all outstanding
shares of Series A Preferred  Stock and Common Stock,  respectively,  holders of
Series A Preferred Stock and holders of Common Stock shall receive their ratable
and  proportionate  share of the remaining assets to be distributed in the ratio
of the Adjustment  Number to 1 with respect to such  Preferred  Stock and Common
Stock, on a per share basis, respectively.

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

     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 the shares of
Series A  Preferred  Stock  shall at the same  time be  similarly  exchanged  or
changed  in an  amount  per  share  (subject  to the  provision  for  adjustment
hereinafter  set  forth)  equal to 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.

     Section 8. No Redemption.  The shares of Series A Preferred Stock shall not
be redeemable.

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

     Section 10.  Amendment.  The Articles of  Incorporation  of the Corporation
shall not be further  amended  in any manner  which  would  materially  alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely  without the affirmative vote of the holders of a
majority or more of the outstanding  shares of Series A Preferred Stock,  voting
separately as a class.

     IN WITNESS WHEREOF,  this Certificate of Amendment is executed on behalf of
the  Corporation by its Chairman of the Board and attested by its Secretary this
27th day of February, 1998.

         NOT EXERCISABLE AFTER FEBRUARY 20, 2008 OR EARLIER IF REDEEMED
                  BY THE CORPORATION, THE RIGHTS ARE SUBJECT TO
                   REDEMPTION AT $.0001 PER RIGHT ON THE TERMS
                        SET FORTH IN THE RIGHTS AGREEMENT

                                Right Certificate
                       Advanced Machine Vision Corporation


     This certifies that ________________________________________ or  registered
assigns,  is the registered owner of the number of Rights set forth above,  each
of which  entitles  the owner  thereof,  subject  to the terms,  provisions  and
conditions of that certain Rights Agreement,  dated as of February 27, 1998 (the
"Rights Agreement"),  between Advanced Machine Vision Corporation,  a California
corporation  (the  "Corporation"),  and American  Stock Transfer & Trust Company
(the "Rights  Agent"),  to purchase from the  Corporation  at any time after the
Distribution  Date (as such term is defined in the Rights  Agreement) and before
5:00 P.M.,  Oregon time, on February 26, 2008 unless the Rights evidenced hereby
shall have been previously redeemed by the Corporation,  at the principal office
or offices of the Rights Agent designated for such purpose,  or at the office of
its successor as Rights Agent, one one-hundredth of a fully paid  non-assessable
share of Series A Junior  Participating  Preferred Stock, without par value (the
"Preferred  Shares"),  of the Corporation,  at a purchase price of $________ per
one one-hundredth of Preferred Share (the "Purchase  Price"),  upon presentation
and  surrender of this Right  Certificate  with the Form of Election to Purchase
duly executed. The number of Rights evidenced by this Right Certificate (and the
number of one  one-hundredths  of a Preferred  Share which may be purchased upon
exercise  hereof) set forth above,  and the Purchase Price set forth above,  are
the number and Purchase Price as of __________, based on the Preferred Shares as
constituted at such date.

     Upon the occurrence of a Section  11(a)(ii)  Event (as such term is defined
in the Rights Agreement),  if the Rights evidenced by this Right Certificate are
beneficially  owned by (i) an  Acquiring  Person or an Affiliate or Associate of
any such Acquiring  Person (as such terms are defined in the Rights  Agreement),
(ii) a transferee  of any such  Acquiring  Person,  Associate  or Affiliate  who
becomes a transferee  after the  Acquiring  Person  becomes such, or (iii) under
certain  circumstances  specified in the Rights  Agreement,  a transferee of any
such Acquiring Person, Associate or Affiliate who becomes a transferee before or
concurrently  with the Acquiring  Person becoming such, such Rights shall become
null and void and no holder  hereof  shall have any right  with  respect to such
Rights from and after the occurrence of such Section 11(a)(ii) Event.

     As provided in the Rights  Agreement,  the Purchase Price and the number of
one  one-hundredths  of a  Preferred  Share or  other  securities  which  may be
purchased  upon the exercise of the Rights  evidenced by this Right  Certificate
are subject to modification and adjustment upon the happening of certain events,
including Triggering Events (as such term is defined in the Rights Agreement).

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

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

     Subject to the provisions of the Rights Agreement,  the Rights evidenced by
this  Certificate  may be redeemed by the  Corporation at a redemption  price of
$.0001 per Right  (subject to  adjustment  as provided in the Rights  Agreement)
payable in cash.

     No  fractional  Preferred  Shares will be issued  upon the  exercise of any
Right  or  Rights   evidenced   hereby  (other  than  fractions  which  are  one
one-hundredth or integral  multiples of one  one-hundredth of a Preferred Share,
which may, at the  election  of the  Corporation,  be  evidenced  by  depositary
receipts),  but in lieu thereof a cash payment will be made,  as provided in the
Rights Agreement.

     No holder of this Right  Certificate  shall be  entitled to vote or receive
dividends or be deemed for any purpose the holder of the Preferred  Shares or of

                                    Exhibit C

                 SUMMARY OF RIGHTS TO PURCHASE PREFERRED SHARES

     On February 17, 1998,  the Board of  Directors of Advanced  Machine  Vision
Corporation  (the  "Corporation")   declared  a  dividend  distribution  of  one
preferred share purchase right (a "Right") for each outstanding share of Class A
and Class B Common  Stock,  without  par value  (the  "Common  Shares"),  of the
Corporation.  The dividend is payable to the  shareholders of record on February
27,  1998  (the  "Record  Date"),  and with  respect  to  Common  Shares  issued
thereafter  until the  Distribution  Date (as  defined  below)  and,  in certain
circumstances,  with respect to Common Stock issued after the Distribution Date.
Except as set forth below, each Right, when it becomes exercisable, entitles the
registered  holder to purchase from the Corporation one one-hundredth of a share
of  Series A Junior  Participating  Preferred  Stock,  without  par  value  (the
"Preferred Shares"),  of the Corporation at a price of $15 per one 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") between the Corporation and American Stock Transfer & Trust
Company, as Rights Agent (the "Rights Agent") dated as of February 27, 1998.

     Initially,  the Rights will be attached  to all  certificates  representing
Common  Shares then  outstanding,  and no separate  Right  Certificates  will be
distributed.  The Rights will  separate from the Common Shares upon the earliest
to occur of (i) ten days  after a person or group of  affiliated  or  associated
persons has  acquired  beneficial  ownership  of 20% or more of the  outstanding
Common Shares (except pursuant to a Permitted Offer, as hereinafter defined); or
(ii) 10 Business Days (as defined in the Rights  Agreement)  (or such later date
as the Board may determine) following the commencement of, or announcement of an
intention to make, a tender offer or exchange  offer the  consummation  of which
would result in a person or group becoming an Acquiring  Person (as  hereinafter
defined) (the earliest of such dates being called the  "Distribution  Date").  A
person or group whose  acquisition of Common Shares causes a  Distribution  Date
pursuant to clause (i) above is an "Acquiring Person." The date that a person or
group becomes an Acquiring Person is the "Shares Acquisition Date."

     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred  solely with the Common Shares.  Until the Distribution Date
(or  earlier  redemption  or  expiration  of  the  Rights),   new  Common  Share
certificates  issued  after the Record Date upon  transfer or new  issuances  of
Common  Shares will  contain a notation  incorporating  the Rights  Agreement by
reference.  Until the Distribution Date (or earlier  redemption or expiration of
the Rights),  the surrender for transfer of any  certificates  for Common Shares
outstanding  as of the  Record  Date,  even if such  notation  or a copy of this
Summary of Rights is not attached thereto,  will also constitute the transfer of
the Rights associated with the Common Shares represented by such certificate. As
soon as  practicable  following the  Distribution  Date,  separate  certificates
evidencing the Rights ("Right Certificates") will be mailed to holders of record
of the Common Shares as of the close of business on the  Distribution  Date (and
to each  initial  record  holder  of  certain  Common  Shares  issued  after the
Distribution Date), and such separate Right Certificates alone will evidence the
Rights.

     The Rights are not exercisable  until the Distribution Date and will expire
at the close of business on February 26, 2008,  unless  earlier  redeemed by the
Corporation as described below.

     In the event that any person becomes an Acquiring  Person (except  pursuant
to a tender or exchange offer (a "Permitted Offer") which is for all outstanding
Common  Shares at a price and on terms  which a majority of members of the Board
of  Directors  (who are not also  officers of the  Corporation  or an  Acquiring
Person or affiliate or associate  thereof)  determines to be adequate and in the
best  interests  of the  Corporation  and  its  shareholders,  other  than  such
Acquiring  Person,  its affiliates and associates),  each holder of a Right will
thereafter  have the right (the  "Flip-In  Right") to receive upon  exercise the
number of Common Shares (or, in certain  circumstances,  one one-hundredths of a
Preferred Share or other  securities of the  Corporation)  having a market value
(immediately before such triggering event) equal to two times the exercise price
of the  Right.  At such  time,  all Rights  that are  beneficially  owned by the
Acquiring Person or any affiliate,  associate or transferee thereof will be null
and void.

     In the event that, at any time following the Shares  Acquisition  Date, (i)
the  Corporation  is  acquired  in  a  merger  or  other  business   combination
transaction  in  which  the  holders  of all of the  outstanding  Common  Shares
immediately  before the  consummation  of the transaction are not the holders of
all of the surviving  corporation's  voting power,  or (ii) more than 50% of the
Corporation's  assets or earning power are sold or  transferred,  in either case
with or to an Acquiring Person or any affiliate or associate or any other person
in which such  Acquiring  Person,  affiliate or associate has an interest or any
person acting on behalf of or in concert with such Acquiring  Person,  affiliate
or associate,  or, if in such  transaction  all holders of Common Shares are not
treated alike,  then each holder of a Right (except Rights which previously have
been voided as set forth above) shall  thereafter have the right (the "Flip-Over
Right") to receive, upon exercise, common shares of the acquiring company having
a value  equal to two times the  exercise  price of the  Right.  The holder of a
Right will  continue  to have the  Flip-Over  Right only to the extent  that the
Flip-In Right has not previously been exercised.

     The  Purchase  Price  payable and the number of  Preferred  Shares,  Common
Shares or other  securities  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
or  warrants  to  subscribe  for or  purchase  Preferred  Shares  at a price (or
conversion price as the case may be), 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 quarterly cash
dividends) or of  subscription  rights or warrants (other than those referred to
above).

     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,
before 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 $1.00 per share but, if greater,  will be entitled
to an aggregate dividend per share 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 $100 per  share;
thereafter,  and after the holders of the Common  Shares  receive a  liquidation
payment of $1.00 per share,  the holders of the Preferred Shares and the holders
of the Common Shares will share the remaining  assets in the ratio of 1 to 1 (as
adjusted)  for each  Preferred  Share and  Common  Share so held,  respectively.
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 protected by
customary antidilution  provisions.  In the event that the amount of accrued and
unpaid  dividends on the Preferred  Shares is  equivalent to six full  quarterly
dividends or more  (whether or not  consecutive),  the holders of the  Preferred
Shares  shall  have the  right,  voting as a class,  to elect two  directors  in
addition to the directors  elected by the holders of the Common Shares until all
cumulative  dividends  on the  Preferred  Shares have been paid through the last
quarterly dividend payment date or until non-cumulative dividends have been paid
regularly for at least one year.

     With  certain  exceptions,  no  adjustment  to the  Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase Price. No fractional  Preferred  Shares will be issued (other than
fractions which are one one-hundredth or integral multiples of one one-hundredth
of a  Preferred  Share,  which  may,  at the  election  of the  Corporation,  be
evidenced by depository receipts) and in lieu thereof, a payment in cash will be
made based on the market price of the  Preferred  Shares on the last Trading Day
(as defined in the Rights Agreement) before the date of exercise.

     At any time  before  the  earlier  to occur  of (i) a  person  becoming  an
Acquiring  Person,  (ii) the  expiration  of the  Rights,  or  (iii) in  certain
circumstances, after the Shares Acquisition Date, the Corporation may redeem all
but not less  than  all of the  Rights  at a price  of  $.0001  per  Right  (the
"Redemption  Price") which  redemption shall be effective upon the action of the
Board of Directors.

     All of the  provisions of the Rights  Agreement may be amended by the Board
of  Directors  of the  Corporation  before  the  Distribution  Date.  After  the
Distribution  Date, the provisions of the Rights Agreement may be amended by the
Board in order to cure any ambiguity,  defect or inconsistency,  to make changes
which do not adversely affect the interests of holders of Rights  (excluding the
interests of any  Acquiring  Person),  or,  subject to certain  limitations,  to
shorten or lengthen any time period under the Rights Agreement.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a shareholder of the Corporation,  including,  without limitation, the
right to vote or to receive dividends. While the distribution of the Rights will
not be taxable to shareholders of the Corporation,  shareholders may,  depending
upon the  circumstances,  recognize  taxable  income  should the  Rights  become
exercisable or upon the occurrence of certain events thereafter.

     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
February 27, 1998.  A copy of the Rights  Agreement is available  free of charge
from the Corporation. 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.
