                         Preferred Share Purchase Rights
                                (Title of Class)







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

     On September  11, 2002 the Board of  Directors  of BioMarin  Pharmaceutical
Inc. (the "Company") authorized a dividend of one preferred share purchase right
(a "Right") for each share of common stock,  $.001 par value per share  ("Common
Shares") of the Company  outstanding  at the close of business on September  23,
2002 (the  "Record  Date").  As long as the  Rights are  attached  to the Common
Shares,  the Company will issue one Right (subject to adjustment)  with each new
Common  Share  so  that  all  such  shares  will  have  attached  Rights.   When
exercisable,  each Right will entitle the registered holder to purchase from the
Company one one-hundredth of a share of Series B Junior Participating  Preferred
Stock  (the  "Preferred  Shares")  at a price of $35.00 per  one-hundredth  of a
Preferred Share,  subject to adjustment (the "Purchase Price").  The description
and  terms  of the  Rights  are set  forth in a  Rights  Agreement,  dated as of
September  11,  2002,  as the same may be amended from time to time (the "Rights
Agreement"),  between the Company and Mellon Investor Services LLC, a New Jersey
limited liability company, as Rights Agent (the "Rights Agent").

     Initially,  the Rights will be attached  to all Common  Stock  certificates
evidencing shares then outstanding,  and no separate Rights certificates will be
distributed.  Until the earlier to occur of (i) ten (10) days following a public
announcement  that a person or group of  affiliated  or  associated  persons has
acquired, or obtained the right to acquire,  beneficial ownership of 15% or more
of the Common Shares (an "Acquiring  Person") or (ii) ten (10) business days (or
such later date as may be determined  by action of the Board of Directors  prior
to such time as any person or group of affiliated  persons  becomes an Acquiring
Person)  following the  commencement  or  announcement of an intention to make a
tender  offer or exchange  offer the  consummation  of which would result in the
beneficial  ownership  by a person or group of 15% or more of the Common  Shares
(the earlier of (i) and (ii) being called the "Distribution  Date"),  the Rights
will be  represented,  with  respect  to any of the  Common  Share  certificates
outstanding as of the Record Date, by such Common Share certificate.

     The Rights Agreement  provides that until the Distribution Date (or earlier
redemption,  exchange, termination or expiration of the Rights), the Rights will
be transferred with and only with the Common Shares. Until the Distribution Date
(or earlier redemption,  exchange, termination or expiration of the Rights), new
Common Share certificates  issued after the close of business on the Record Date
upon  transfer  or new  issuance of the Common  Shares  will  contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier  redemption,  exchange,  termination  or expiration of the Rights),  the
surrender for transfer of any  certificates  for Common Shares,  with or without
such  notation or a copy of this  Summary of Rights,  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  representing the Rights ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution Date and such separate Right  Certificates alone will represent the
Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on September 23, 2012 subject to the Company's  right to extend such date
(the "Final  Expiration  Date"),  unless  earlier  redeemed or  exchanged by the
Company or terminated.



     Each  Preferred  Share  purchasable  upon  exercise  of the Rights  will be
entitled, when, as and if declared, to a minimum preferential quarterly dividend
payment of $0.01 per share but will be entitled to an aggregate  dividend of 100
times  the  dividend,  if any,  declared  per  Common  Share.  In the  event  of
liquidation,  dissolution  or  winding  up of the  Company,  the  holders of the
Preferred Shares will be entitled to a minimum preferential  liquidation payment
of  $10,000  per share  (plus any  accrued  but  unpaid  dividends)  but will be
entitled to an aggregate payment of 100 times the payment made per Common Share.
Each Preferred  Share will have 100 votes and will vote together with the Common
Shares. Finally, in the event of any merger,  consolidation or other transaction
in which Common Shares are exchanged,  each Preferred  Share will be entitled to
receive 100 times the amount  received per Common Share.  Preferred  Shares will
not  be  redeemable.  These  rights  are  protected  by  customary  antidilution
provisions. Because of the nature of the Preferred Share's dividend, liquidation
and  voting  rights,  the  value  of  one  one-hundredth  of a  Preferred  Share
purchasable  upon  exercise of each Right  should  approximate  the value of one
Common Share.

     The Purchase  Price  payable,  and the number of Preferred  Shares or other
securities  or  property  issuable,  upon  exercise of the Rights are subject to
adjustment  from time to time to  prevent  dilution  (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares or  convertible
securities  at less than the current  market  price of the  Preferred  Shares or
(iii) upon the  distribution to holders of the Preferred  Shares of evidences of
indebtedness,  cash,  securities or assets or of subscription rights or warrants
(other than those referred to above).

     In the event that a person becomes an Acquiring Person or if the Company is
the surviving  corporation in a merger with an Acquiring Person or any affiliate
or associate of an  Acquiring  Person and the Common  Shares were not changed or
exchanged,  each holder of a Right,  other than Rights that are or were acquired
or beneficially  owned by the Acquiring Person (which Rights will be void), will
thereafter  have the right to receive,  upon  exercise  thereof,  that number of
Common Shares having a market value of two times the then-current Purchase Price
of the Right. In the event that, after a person has become an Acquiring  Person,
the Company is acquired in a merger or other business combination transaction or
more than 50% of its assets or earning power are sold, proper provision shall be
made so that each holder of a Right shall  thereafter have the right to receive,
upon the exercise thereof at the then-current  Purchase Price of the Right, that
number of shares of common stock of the  acquiring  company which at the time of
such  transaction  would  have a market  value  of two  times  the  then-current
Purchase Price of the Right.

     For example, at an exercise price of $35.00 per Right, each Right not owned
by an Acquiring Person (or by certain related parties) following a Trigger Event
would  entitle its holder to  purchase  $70.00  worth of Common  Stock (or other
consideration,  as noted above) for $35.00. Assuming that the Common Stock had a
per share value of $10.00 at such time,  the holder of each valid Right would be
entitled to purchase seven shares of Common Stock for $35.00.



     At any time  after a person  becomes an  Acquiring  Person and prior to the
earlier of one of the events  described  in the last  sentence  of the  previous
paragraph  or the  acquisition  by such  Acquiring  Person of 50% or more of the
outstanding  Common  Shares,  the Board of  Directors  may cause the  Company to
exchange the Rights (other than Rights owned by an Acquiring Person,  which will
be  void),  in whole or in part,  for that  number of  Common  Shares  having an
aggregate  value  equal to the  Spread  (the  excess of the value of the  Common
Shares  issuable upon the exercise of a Right over the Purchase Price) per Right
(subject to adjustment).

     No  adjustment  in the  Purchase  Price will be required  until  cumulative
adjustments  require an  adjustment  of at least 1% in the  Purchase  Price.  No
fractional  Preferred  Shares  or  Common  Shares  will be  issued  (other  than
fractions of Preferred Shares which are integral  multiples of one one-hundredth
of a Preferred Share, which may, at the election of the Company,  be represented
by depository  receipts),  and in lieu  thereof,  a payment in cash will be made
based on the market price of the  Preferred  Shares or Common Shares on the last
trading date prior to the date of exercise.

     The Rights may be redeemed in whole,  but not in part,  at a price of $.001
per Right (the  "Redemption  Price") by the Board of Directors at any time prior
to the time that an Acquiring  Person has become  such.  The  redemption  of the
Rights  may be made  effective  at  such  time,  on such  basis  and  with  such
conditions  as the Board of  Directors  in its sole  discretion  may  establish.
Immediately upon any redemption of the Rights,  the right to exercise the Rights
will  terminate  and the only right of the  holders of Rights will be to receive
the Redemption Price.

     Until a Right is exercised, it will not entitle its holder to any rights as
a stockholder of the Company,  including,  without limitation, the right to vote
or to receive dividends.

     Any of the  provisions of the Rights  Agreement may be amended by the Board
of Directors for so long as the Rights are then redeemable, and after the Rights
are no longer  redeemable,  the  Company  may  amend or  supplement  the  Rights
Agreement  in any manner that does not  adversely  affect the  interests  of the
holders of the Rights.

     The Rights are  designed to assure that all of the  Company's  stockholders
receive fair and equal  treatment  in the event of any proposed  takeover of the
Company and to guard against  partial tender offers,  open market  accumulations
and other  abusive  tactics to gain  control of the Company  without  paying all
stockholders a control premium.  The Rights will cause substantial dilution to a
person or group that  acquires 15% or more of the  Company's  stock on terms not
approved by the Company's  Board of  Directors.  The Rights should not interfere
with any merger or other business combination approved by the Board of Directors
at any time before a person or group has become an Acquiring Person.

     Rights  Agreement,  dated  as  of  September  11,  2002,  between  BioMarin

                                    RECITALS

     WHEREAS,  on  September  11,  2002,  the Board of  Directors  adopted  this
Agreement,  and has authorized a dividend of one preferred  share purchase right
(a "Right") for each Common Share (as defined in Section 1.7) outstanding at the
close of business on September 23, 2002 (the "Record  Date") and has  authorized
and  directed  the  issuance  of one Right  (subject to  adjustment  as provided
herein) with respect to each Common Share that shall become outstanding  between
the Record Date and the  earliest of the  Distribution  Date and the  Expiration
Date (as such terms are defined in Sections 3.1 and 7.1),  each Right  initially
representing the right to purchase one one-hundredth  (subject to adjustment) of
a share  of  Series B  Junior  Participating  Preferred  Stock  (the  "Preferred
Shares") of the Company having the rights,  powers and  preferences set forth in
the form of Certificate of  Designation,  Preferences and Rights attached hereto
as  Exhibit  A, upon the terms and  subject to the  conditions  hereinafter  set
forth;  provided,  however,  that  Rights may be issued  with  respect to Common
Shares that shall become  outstanding  after the Distribution  Date and prior to
the Expiration Date in accordance with Section 22.

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

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

     1.1  "Acquiring  Person" shall mean any Person (as such term is hereinafter
defined) who or which,  together with all  Affiliates  and  Associates  (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is  hereinafter  defined)  of 15% or more of the Common  Shares of the
Company then outstanding but shall not include an Exempt Person (as such term is
hereinafter defined).  Notwithstanding the foregoing,  no Person shall become an
"Acquiring  Person" due to such Person  becoming the Beneficial  Owner of 15% or
more of the Common  Shares as a result of the  issuance by the Company of Common
Shares to such Person in consideration for the sale,  contribution,  conveyance,
transfer,  assignment or delivery of property,  services or other assets by such
Person to the Company. Notwithstanding the first sentence of this Section 1.1,

                                       1


         (i)      no Person shall become an "Acquiring Person" as the result of
     an  acquisition  of Common  Shares by the Company  which,  by reducing  the
     number of shares outstanding,  increases the proportionate number of shares
     beneficially  owned by such  Person to 15% or more of the Common  Shares of
     the Company then outstanding,

         (ii)     no Person shall become an "Acquiring Person" as the result of
     the  acquisition  of Common Shares from an  individual  who, on the date of
     this Agreement, is the Beneficial Owner of 15% or more of the Common Shares
     if such Common Shares are received upon that individual's death pursuant to
     that  individual's  will or pursuant to a charitable  trust created by that
     individual for estate planning purposes, and


         (iii)    no Person shall become an "Acquiring Person" as the result of
     the beneficial  ownership of (A) Common Shares  beneficially  owned by such
     Person  on the date  hereof  unless  such  Person  becomes,  after the date
     hereof,  the  Beneficial  Owner of an  additional  1% or more of the Common
     Shares outstanding or (B) Common Shares beneficially owned as the result of
     stock  dividends,  subdivisions  or similar  transactions  with  respect to
     Common Shares;

         provided, however, that if a Person shall become the Beneficial Owner
of 15% or more of the Common  Shares of the Company then  outstanding  solely by
reason of share purchases by the Company or by reason of shares received upon an
individual's death as aforesaid and shall thereafter become the Beneficial Owner
of one or more additional Common Shares of the Company (other than pursuant to a
dividend or distribution  paid or made by the Company on the outstanding  Common
Shares in Common Shares or pursuant to a split or subdivision of the outstanding
Common  Shares),  then such Person shall be deemed to be an  "Acquiring  Person"
unless upon becoming the Beneficial Owner of such additional  Common Shares such
Person  does  not  beneficially  own  15% or  more  of the  Common  Shares  then
outstanding.

         1.1.1 Notwithstanding the foregoing, if the Board of Directors
determines  in good  faith that a Person who would  otherwise  be an  "Acquiring
Person," as defined  pursuant to the  foregoing  provisions of this Section 1.1,
has become such inadvertently (including,  without limitation,  because (A) such
Person was unaware that it beneficially owned a percentage of Common Shares that
would otherwise cause such Person to be an "Acquiring  Person",  (B) such Person
was aware of the extent of its  Beneficial  Ownership of Common Stock but had no
actual  knowledge of the  consequences of such  Beneficial  Ownership under this
Agreement or (C) such Person became an  "Acquiring  Person" as the result of the
formation of a group (as that term is used in the definition of "Person" in this
Agreement) and such Person had no actual  knowledge of the  consequences  of the
formation of such a group under this  Agreement),  and without any  intention of
changing or influencing control of the Company, and such Person, if requested by
the Board of Directors,  divests itself as promptly as reasonably practicable of
Beneficial Ownership of 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  1.1,  then such Person shall not be deemed to be or
have  become  an  "Acquiring  Person"  at any  time  for  any  purposes  of this
Agreement.

                                       2


         1.1.2 For all purposes of this Agreement, any calculation of the number
of Common Shares  outstanding at any particular time,  including for purposes of
determining the particular percentage of such outstanding Common Shares of which
any Person is the Beneficial  Owner,  shall be made in accordance  with the last
sentence of Rule  13d-3(d)(1)(i)  of the General Rules and Regulations under the
Securities  Exchange Act of 1934, as amended (the "Exchange  Act"), as in effect
on the date of this Agreement.

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

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

             (i)      which such Person or any of such Person's Affiliates or
     Associates   beneficially  owns,  directly  or  indirectly  (as  determined
     pursuant  to Rule  13d-3 of the  General  Rules and  Regulations  under the
     Exchange Act as in effect on the date of this Agreement, subject to Section
     1.1.2);

             (ii)     which such Person or any of such Person's Affiliates or
     Associates,  directly or indirectly,  has (A) the right to acquire (whether
     such right is exercisable  immediately,  or only after the passage of time,
     compliance  with  regulatory  requirements,  fulfillment  of a condition or
     otherwise) pursuant to any agreement, arrangement or understanding, whether
     or not in  writing  (other  than  customary  agreements  with  and  between
     underwriters  and selling  group members with respect to a bona fide public
     offering  of  securities),  or upon  the  exercise  of  conversion  rights,
     exchange  rights,  rights,  warrants or options,  or  otherwise;  provided,
     however,  that a Person shall not be deemed the Beneficial  Owner of, or to
     beneficially own, (w) 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,  (x)  securities  which such  Person has a right to
     acquire  upon the exercise of Rights at any time prior to the time that any
     Person  becomes an  Acquiring  Person,  (y)  securities  issuable  upon the
     exercise  of Rights  from and after the time  that any  Person  becomes  an
     Acquiring Person if such Rights were acquired by such Person or any of such
     Person's  Affiliates  or  Associates  prior  to the  Distribution  Date  or
     pursuant to Sections 3.1 or Section 22  ("Original  Rights") or pursuant to
     Sections 11.9 or 11.15 with respect to an adjustment to Original  Rights or
     (z)  securities  which such Person or any of such  Person's  Affiliates  or
     Associates  may  acquire,  does or do  acquire or may be deemed to have the
     right to  acquire,  pursuant to any merger or other  acquisition  agreement
     between the Company  and such Person (or one or more of his  Affiliates  or
     Associates)  if such  agreement has been approved by the Board of Directors
     prior to such Person's  becoming an Acquiring  Person;  or (B) the right to
     vote pursuant to any agreement,  arrangement or  understanding  (whether or
     not in writing);  provided,  however, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, any security under this clause
     (B) 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 of the Exchange Act
     and (2) is not also then  reportable on Schedule 13D under the Exchange Act
     (or any comparable or successor report); or

                                       3


             (iii)    which are beneficially owned, directly or indirectly, by
     any other Person (or any  Affiliate or Associate  thereof) and with respect
     to 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),  whether or not in
     writing, for the purpose of acquiring,  holding, voting (except pursuant to
     a  revocable  proxy or  consent  as  described  in the  proviso  to Section
     1.3(ii)(B))  or  disposing  of any  securities  of the  Company;  provided,
     however, that no Person who is an officer, director, trustee or employee of
     an Exempt Person shall be deemed,  solely by reason of such Person's status
     or authority as such, to be the "Beneficial  Owner" of, to have "Beneficial
     Ownership"  of  or  to   "beneficially   own"  any   securities   that  are
     "beneficially owned" (as defined in this Section 1.3),  including,  without
     limitation,  in a fiduciary  capacity,  by an Exempt Person or by any other
     such officer, director, trustee or employee of an Exempt Person.

Company.

Business Day.

         1.7      "Common Shares" shall mean the shares of common stock, $.001
par value per share,  of the Company;  provided,  however,  that "Common Shares"
when used with  reference  to any Person  other than the Company  shall mean the

equity interest having power to control or direct the management,  of such other
Person or, if such Person is a Subsidiary (as such term is hereinafter  defined)

                  The following terms shall have the meanings defined for such

Agent.  The Rights Agent shall have no duty to supervise,  and shall in no event
be liable for, the acts or omissions of any such co-Rights  Agent.  In the event

        Section 3.        Issuance of Right Certificates.

                3.1 Rights Represented by Share Certificates. Until the earlier
of (i) the  tenth day after  the  Shares  Acquisition  Date (or if the tenth day
after the Shares  Acquisition  Date occurs before the Record Date,  the Close of
Business on the Record  Date) or (ii) the tenth  Business  Day after the date of
the  commencement  of, or first public  announcement of the intent of any Person
(other  than an Exempt  Person)  to  commence,  a tender or  exchange  offer the
consummation  of which would result in any Person (other than an Exempt  Person)
becoming the Beneficial  Owner of Common Shares  aggregating  15% or more of the
then outstanding Common Shares of the Company (the earlier of (i) and (ii) being
herein referred to as the "Distribution  Date"),  (x) the Rights (unless earlier
expired,  redeemed or terminated) will be represented (subject to the provisions
of Section 3.2) by the certificates for Common Shares registered in the names of
the holders thereof (which  certificates  for Common Shares shall also be deemed
to be Right Certificates) and not by separate  certificates,  and (y) the Rights
(and the right to receive  certificates  therefor) will be transferable  only in
connection  with the transfer of the  underlying  Common  Shares.  The preceding
sentence  notwithstanding,  prior to the occurrence of a Distribution  Date as a
result of an event described in clause (ii) (or such later  Distribution Date as
the Board of  Directors  may select  pursuant  to this  sentence),  the Board of
Directors may postpone,  one or more times,  the  Distribution  Date which would
occur as a result of an event described in clause (ii) beyond the date set forth
in such clause  (ii).  Nothing  herein  shall  permit such a  postponement  of a
Distribution Date after a Person becomes an Acquiring Person, except as a result
of the operation of Section 1.1.1. As soon as practicable after the Distribution
Date,  the Company will prepare and execute,  the Rights Agent will  countersign
and the Company (or, if requested  and provided with a list of  stockholders  of
Common Stock, the Rights Agent) will send, by first-class, postage-prepaid mail,
to each  record  holder of Common  Shares  as of the  close of  business  on the
Distribution Date (other than any Acquiring Person or any Associate or Affiliate
of an Acquiring  Person),  at the address of such holder shown on the records of
the Company,  one or more  certificates for Rights, in substantially the form of
Exhibit B hereto (a "Right  Certificate"),  representing  one Right  (subject to
adjustment  as provided  herein) for each Common Share.  As of the  Distribution
Date, the Rights will be represented solely by such Right  Certificates.  In the
event that an  adjustment  in the number of Rights per share of Common Stock has
been made pursuant to Section 11.15 hereof,  at the time of  distribution of the
Rights  Certificates  the  Company  shall  make the  necessary  and  appropriate
rounding  adjustments  (in  accordance  with Section 14.1 hereof) so that Rights
Certificates evidencing only whole numbers of Rights are distributed and cash is
paid in lieu of any fractional Rights.

                3.2 Summary of Rights. On the Record Date or as soon as
practicable  thereafter,  the Company  will send or cause to be sent a copy of a
Summary  of Rights to  Purchase  Preferred  Shares,  in  substantially  the form
attached  hereto  as  Exhibit  C (the  "Summary  of  Rights"),  by  first-class,
postage-prepaid  mail, to each record holder of Common Shares as of the close of
business on the Record  Date at the address of such holder  shown on the records
of the Company. With respect to certificates for Common Shares outstanding as of
the close of business on the Record Date,  until the  Distribution  Date (or the
earlier  Expiration  Date), the Rights will be represented by such  certificates
for  Common  Shares  registered  in the  names of the  holders  thereof  and the
registered  holders of the Common Shares shall also be registered holders of the
associated Rights. Until the Distribution Date (or the earlier Expiration Date),
the surrender for transfer of any certificate  for Common Shares  outstanding at
the close of business on the Record Date,  with or without a copy of the Summary
of Rights,  shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

                                       7


                3.3 New Certificates After Record Date. Certificates for Common
Shares which become  outstanding  (whether upon  issuance out of authorized  but
unissued  Common Shares or transfer or exchange of  outstanding  Common  Shares)
after the Record Date, but prior to the earlier of the Distribution  Date or the
Expiration Date, shall have impressed,  printed,  stamped,  written or otherwise
affixed onto them the following legend:

               "This  certificate also represents and entitles the holder hereof
               to certain rights ("Rights") as set forth in an agreement between
               BioMarin  Pharmaceutical Inc. (the "Company") and Mellon Investor
               Services LLC as Rights Agent,  dated as of September 11, 2002, as
               the same may be amended from time to time (the "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
               the Company.  Under  certain  circumstances,  as set forth in the
               Agreement,   such   Rights  will  be   represented   by  separate
               certificates   and  will  no  longer  be   represented   by  this
               certificate.  The  Company  will  mail  to  the  holder  of  this
               certificate a copy of the Agreement  without charge after receipt
               of a written  request  therefor.  As described in the  Agreement,
               Rights which are owned by,  transferred  to or have been owned by
               Acquiring Persons or Associates or Affiliates thereof (as defined
               in the  Agreement)  shall become null and void and will no longer
               be transferable."

                    With respect to such certificates containing the foregoing
legend, until the Distribution Date (or the earlier Expiration Date), the Rights
associated  with the Common Shares  represented  by such  certificates  shall be
represented by such  certificates  alone,  and the surrender for transfer of any
such certificates,  except as otherwise  provided herein,  shall also constitute
the  transfer  of the  Rights  associated  with the  Common  Shares  represented
thereby.  In the event that the Company  purchases or acquires any Common Shares
after the Record Date but prior to the Distribution  Date, any Rights associated
with such  Common  Shares  shall be deemed  cancelled  and  retired  so that the
Company shall not be entitled to exercise any Rights  associated with the Common
Shares which are no longer outstanding.

                    Notwithstanding this Section 3.3, the omission of a legend
shall not affect the  enforceability of any part of this Agreement or the rights
of any holder of the Rights.

                                       8


        Section 4.        Form of Right Certificates.

                4.1 The Right Certificates (and the forms of election to
purchase  shares,  certification  and  assignment  to be printed on the  reverse
thereof)  shall be  substantially  in the form of  Exhibit B hereto and may have
such marks of  identification  or  designation  and such  legends,  summaries or
endorsements  printed thereon as the Company may deem appropriate,  which do not
affect the rights, duties or responsibilities of the Rights Agent and as are not
inconsistent  with the  provisions of this  Agreement,  or as may be required to
comply with any  applicable  law or with any rule or  regulation  made  pursuant
thereto or with any rule or regulation of any stock  exchange or trading  system
on which the Rights may from time to time be listed or quoted,  or to conform to
usage.  Subject  to the terms and  conditions  hereof,  the Right  Certificates,
whenever  issued,  shall be dated as of the Record Date, and shall show the date
of  countersignature  by the Rights  Agent,  and on their face shall entitle the
holders thereof to purchase such number of  one-hundredths  of a Preferred Share
as shall be set forth  therein  at the price per  one-hundredth  of a  Preferred
Share  set  forth  therein  (the  "Purchase  Price"),  but  the  number  of such
one-hundredths  of a Preferred  Share and the Purchase Price shall be subject to
adjustment as provided herein.

                4.2 Any Rights Certificate issued pursuant to Sections 3.1 or
Section 22 hereof that evidences Rights  beneficially  owned by any Person known
to be (i) an  Acquiring  Person or any  Associate  or  Affiliate of an Acquiring
Person, (ii) a transferee of any Person (or of any Associate or Affiliate of any
Person) who becomes a transferee after such Person becomes an Acquiring  Person,
or (iii) a  transferee  of any Person (or of any  Associate  or Affiliate of any
Person)  who  becomes a  transferee  prior to or  concurrently  with such Person
becoming an Acquiring  Person and receives such Rights  pursuant to either (A) a
transfer  (whether  or not for  consideration)  from  such  Acquiring  Person to
holders of equity  interests in such Acquiring Person or to any Person with whom
such Acquiring Person has any continuing agreement, arrangement or understanding
regarding the transferred  Rights, or (B) a transfer that the Board of Directors
of the Company has determined is part of a plan,  arrangement  or  understanding
that has as a primary purpose or effect avoidance of Section 7.5 hereof, and any
Rights  Certificate  issued  pursuant  to Section 6 or  Section  11 hereof  upon
transfer,  exchange,  replacement or adjustment of any other Rights  Certificate
referred  to in this  sentence,  shall  contain  (to the  extent  feasible)  the
following legend:

               "The  Rights  evidenced  by this Rights  Certificate  are or were
               beneficially  owned by a Person  who was or became  an  Acquiring
               Person or an Affiliate  or  Associate of an Acquiring  Person (as
               such  terms are  defined  in the  Rights  Agreement  between  the
               Company  and the Rights  Agent and its  successors  (the  "Rights
               Agreement")). Accordingly, this Rights Certificate and the Rights
               evidenced  hereby may become  null and void in the  circumstances
               specified in Section 7.6 of the Rights Agreement."

                                       9


     Section 5. Countersignature and Registration.  The Right Certificates shall
be executed on behalf of the Company by its Chairman of the Board of  Directors,
Chief Executive  Officer or any Vice President,  either manually or by facsimile
signature,  and shall have  affixed  thereto the  Company's  seal or a facsimile
thereof which shall be attested by the Secretary, or any Assistant Secretary, of
the Company,  either manually or by facsimile signature.  The Right Certificates
shall  be  countersigned,  either  manually  or by  facsimile  signature,  by an
authorized  signatory of the Rights Agent, but it shall not be necessary for the
same signatory to countersign all of the Right Certificates  hereunder. No Right
Certificate shall be valid for any purpose unless so countersigned.  In case any
officer of the Company who shall have signed any of the Right Certificates shall
cease to be such officer of the Company  before  countersignature  by the Rights
Agent and  issuance  and  delivery  by the  Company,  such  Right  Certificates,
nevertheless, may be countersigned by the Rights Agent, and issued and delivered
by the  Company  with the same  force and effect as though the person who signed
such Right  Certificates  had not ceased to be such officer of the Company;  and
any Right  Certificate may be signed on behalf of the Company by any person who,
at the actual date of the execution of such Right Certificate, shall be a proper
officer of the Company to sign such Right  Certificate,  although at the date of
the execution of this Agreement any such person was not such an officer.

            Following the Distribution Date and receipt by the Rights Agent of
all relevant information, the Rights Agent will keep or cause to be kept, at its
office,  designated to the Company for such purposes, 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 represented on its face by each of the Right Certificates,  the
certificate number of each of the Right Certificates and the date of each of the
Right Certificates.

     Section  6.  Transfer,   Split  Up,   Combination  and  Exchange  of  Right
Certificates;  Mutilated, Destroyed, Lost or Stolen Right Certificates.  Subject
to the provisions of Sections 7.6,  11.1.2 and Section 14, at any time after the
Close of  Business  on the  Distribution  Date,  and at or prior to the Close of
Business on the  Expiration  Date, any Right  Certificate or Right  Certificates
(other  than  Right  Certificates  representing  Rights  that have  become  void
pursuant to Section 11.1.2 or that have been  exchanged  pursuant to Section 27)
may be  transferred,  split  up or  combined  or  exchanged  for  another  Right
Certificate or Right  Certificates,  entitling the registered holder to purchase
the same number of  one-hundredths of a Preferred Share as the Right Certificate
or Right  Certificates  surrendered  then entitled such holder to purchase.  Any
registered  holder  desiring to  transfer,  split up or combine or exchange  any
Right  Certificate  shall make such  request in writing  delivered to the Rights
Agent,  and shall  surrender,  together with any required form of assignment and
certificate duly completed,  the Right  Certificate or Right  Certificates to be
transferred, split up or combined or exchanged at the office of the Rights Agent
designated  for such purpose.  Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered Right Certificate or Right  Certificates until the registered holder
shall  have  completed  and  signed  the  certificate  contained  in the form of
assignment on the reverse side of such Right  Certificate or Right  Certificates
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 Company  shall  reasonably  request.  Thereupon  the Rights Agent
shall countersign and deliver to the person entitled thereto a Right Certificate
or Right  Certificates,  as the case may be, as so  requested.  The  Company may
require  payment from the holders of Right  Certificates  of a sum sufficient to
cover any tax or governmental  charge that may be imposed in connection with any
transfer,  split up or combination or exchange of such Right  Certificates.  The
Rights  Agent shall have no duty or  obligation  under this Section 6 unless and
until it is satisfied that all such taxes and/or charges have been paid in full.

                                       10


                  Subject to the provisions of Section 11.1.2, at any time after
the  Distribution  Date and prior to the  Expiration  Date,  upon receipt by the
Company and the Rights Agent of evidence reasonably  satisfactory to them of the
loss, theft,  destruction or mutilation of a Right Certificate,  and, in case of
loss, theft or destruction,  of indemnity or security satisfactory to them, and,
at the Company's  request,  reimbursement to the Company and the Rights Agent of
all reasonable  expenses  incidental  thereto,  and upon surrender to the Rights
Agent and cancellation of the Right  Certificate if mutilated,  the Company will
make and deliver a new Right  Certificate  of like tenor to the Rights Agent for
countersignature  and  delivery  to the  registered  owner in lieu of the  Right
Certificate so lost, stolen, destroyed or mutilated.

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

                7.1 Exercise of Rights. Subject to Section 11.1.2 and except as
otherwise  provided herein,  the registered  holder of any Right Certificate may
exercise  the Rights  represented  thereby 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  certification  on the  reverse  side  thereof  duly
executed,  to the Rights Agent at the office of the Rights Agent  designated for
such  purpose,  together with payment of the  aggregate  Purchase  Price for the
total number of one-hundredths  of a Preferred Share (or other securities,  cash
or other assets) as to which the Rights are  exercised,  at or prior to the time
(the  "Expiration  Date")  that is the  earliest of (i) the Close of Business on
September  23, 2012 (the "Final  Expiration  Date"),  (ii) the time at which the
Rights are redeemed as provided in Section 23 (the "Redemption Date"), (iii) the
closing of any merger or other  acquisition  transaction  involving  the Company
pursuant to an agreement of the type  described  in Sections  1.3(ii)(A)(z)  and
13.3,  at which time the Rights  are  terminated,  or (iv) the time at which the
Rights are exchanged as provided in Section 27.

                7.2 Purchase. The Purchase Price for each one-hundredth of a
Preferred  Share pursuant to the exercise of a Right shall be initially  $35.00,
shall be subject to  adjustment  from time to time as  provided  in Section  11,
Section 13 and  Section  26 and shall be  payable in lawful  money of the United
States of America in accordance with Section 7.3.

                7.3 Payment  Procedures.  Upon  receipt of a  Right Certificate
representing  exercisable  Rights,  with the form of election  to  purchase  and
certification  duly executed,  accompanied by payment of the aggregate  Purchase
Price  for the  total  number  of  one-hundredths  of a  Preferred  Share  to be
purchased and an amount equal to any applicable transfer tax required to be paid
by the holder of such Right Certificate in accordance with Section 9, in cash or
by  certified  or  cashier's  check or money  order  payable to the order of the
Company,  the Rights Agent shall thereupon  promptly (i)(A) requisition from any
transfer agent of the Preferred  Shares (or make available,  if the Rights Agent
is the transfer agent)

                                       11


certificates  for the number of Preferred Shares to be purchased and the Company
hereby  irrevocably  authorizes  its  transfer  agent  to  comply  with all such
requests,  or (B) if the Company  shall have elected to deposit the total number
of  Preferred  Shares  issuable  upon  exercise of the Rights  hereunder  with a
depositary  agent,  requisition from the depositary  agent  depositary  receipts
representing  interests in such number of one-hundredths of a Preferred Share as
are to be  purchased  (in  which  case  certificates  for the  Preferred  Shares
represented  by such receipts  shall be deposited by the transfer agent with the
depositary  agent) and the Company hereby directs the depositary agent to comply
with all such requests, (ii) when appropriate,  requisition from the Company the
amount  of cash to be paid in lieu  of the  issuance  of  fractional  shares  in
accordance  with Section 11.14 or otherwise in accordance  with Section  11.1.3,
(iii) promptly after receipt of such certificates or depositary receipts,  cause
the same to be delivered to or upon the order of the  registered  holder of such
Right Certificate, registered in such name or names as may be designated by such
holder and (iv) when appropriate,  after receipt,  promptly deliver such cash to
or upon the order of the  registered  holder of such Right  Certificate.  In the
event that the Company is  obligated to issue other  securities  of the Company,
pay cash  and/or  distribute  other  property  pursuant to Section  11.1.3,  the
Company will make all arrangements necessary so that such other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when necessary to comply with this Agreement.

                7.4 Partial Exercise. In case the registered holder of any Right
Certificate shall exercise less than all the Rights  represented  thereby, a new
Right  Certificate  representing  Rights  equivalent  to  the  Rights  remaining
unexercised  shall be issued by the Rights Agent and delivered to the registered
holder of such Right Certificate or to his duly authorized  assigns,  subject to
the provisions of Section 6 and Section 14.

                7.5 Rights held by an Acquiring Person. Notwithstanding anything
in this  Agreement to the  contrary,  from and after the first  occurrence  of a
Trigger Event,  any Rights  beneficially  owned by (i) an Acquiring Person or an
Associate or Affiliate of an Acquiring  Person,  (ii) a transferee of any Person
(or of any Associate or Affiliate of any Person) who becomes a transferee  after
such Person becomes an Acquiring Person, or (iii) a transferee of any Person (or
of any  Associate or Affiliate of any Person) who becomes a transferee  prior to
or concurrently  with such Person becoming an Acquiring Person and receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
such  Acquiring  Person (or any  Affiliate or  Associate  thereof) to holders of
equity  interests  in such  Acquiring  Person  (or any  Affiliate  or  Associate
thereof) or to any Person with whom such  Acquiring  Person (or any Affiliate or
Associate  thereof) has any continuing  agreement,  arrangement or understanding
regarding the  transferred  Rights or (B) a transfer that the Board of Directors
of the Company  has  determined  is part of a plan,  agreement,  arrangement  or
understanding  that has as a primary  purpose  or effect the  avoidance  of this
Section 7.5, shall become null and void without any further action and no holder
of such Rights  shall have any rights  whatsoever  with  respect to such Rights,
whether  under any provision of this  Agreement or otherwise.  The Company shall
notify  the  Rights  Agent  when  this  Section  7.5  applies  and shall use all
reasonable  efforts to ensure that the provisions of Sections 7.5 and 4.2 hereof
are complied  with,  but neither the Company nor the Rights Agent shall have any
liability  to any holder of Rights  Certificates  or other Person as a result of
the Company's  failure to make any  determinations  with respect to an Acquiring
Person or any of its Affiliates, Associates or transferees hereunder.

                                       12


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

     Section 8.  Cancellation and Destruction of Right  Certificates.  All Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split-up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for cancellation or in 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 Company shall deliver to the Rights
Agent for cancellation and retirement,  and the Rights Agent shall so cancel and
retire,  any other  Right  Certificate  purchased  or  acquired  by the  Company
otherwise  than upon the exercise  thereof.  The Rights Agent shall  deliver all
cancelled Right Certificates to the Company, or shall, at the written request of
the Company,  destroy such cancelled Right Certificates,  and in such case shall
deliver a certificate of destruction thereof to the Company.

     Section 9. Reservation and Availability of Stock. The Company covenants and
agrees  that from and after the  Distribution  Date it will cause to be reserved
and kept  available out of its authorized  and unissued  Preferred  Shares (and,
following the occurrence of a Trigger Event,  out of its authorized and unissued
Common  Shares  or other  securities)  the  number  of  Preferred  Shares  (and,
following  the  occurrence  of a  Trigger  Event,  Common  Shares  and/or  other
securities)  that will be  sufficient  to  permit  the  exercise  in full of all
outstanding Rights.

                  So long as the Preferred Shares (and, following the occurrence
of a Trigger  Event,  Common Shares and/or other  securities)  issuable upon the
exercise  of  Rights  may be  listed  on any  stock  exchange  or  traded in the
over-the-counter  market and quoted on Nasdaq,  the  Company  shall use its best
efforts to cause, from and after such time as the Rights become exercisable, all
shares  reserved  for such  issuance to be listed or admitted to trading on such
exchange  or  quoted on  Nasdaq  upon  official  notice  of  issuance  upon such
exercise.

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

                                       13


                  From and after such time as the Rights become exercisable, the
Company shall use its best efforts,  if then necessary to permit the issuance of
Preferred  Shares upon the  exercise of Rights,  to  register  and qualify  such
Preferred Shares under the Securities Act and any applicable state securities or
"Blue Sky" laws (to the extent  exemptions  therefrom are not available),  cause
such  registration  statement and  qualifications to become effective as soon as
possible  after  such  filing  and keep  such  registration  and  qualifications
effective  until the  earlier  of the date as of which the  Rights are no longer
exercisable  for such  securities  and the  Expiration  Date.  The  Company  may
temporarily  suspend,  for a period of time not to exceed ninety (90) days,  the
exercisability  of the  Rights  in order  to  prepare  and  file a  registration
statement under the Securities Act and permit it to become  effective.  Upon any
such suspension,  the Company shall promptly notify the Rights Agent thereof and
issue a public  announcement  stating that the  exercisability of the Rights has
been temporarily suspended, as well as a public announcement (with prompt notice
thereof  to the  Rights  Agent) at such time as the  suspension  is no longer in
effect.  In  addition,  if the  Company  shall  determine  that  a  registration
statement is required  following the Distribution  Date, and a Trigger Event has
not  occurred,  the Company may  temporarily  suspend (and shall give the Rights
Agent prompt notice thereof) the  exercisability  of Rights until such time as a
registration   statement  has  been  declared  effective.   Notwithstanding  any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any  jurisdiction  unless the requisite  qualification  in such  jurisdiction
shall have been obtained and until a registration statement under the Securities
Act (if required) shall have been declared effective.

                  The Company further covenants and agrees that it will pay when
due and payable any and all 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 Company shall not, however,  be required to pay any tax or charge
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
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  representing Rights surrendered for exercise or to issue or deliver
any certificates for Preferred Shares (or Common Shares and/or other securities,
as the case may be) in a name other than that of the registered  holder upon the
exercise  of any Rights  until any such tax or charge  shall have been paid (any
such tax or charge being payable by the holder of such Right  Certificate at the
time  of  surrender)  or  until  it  has  been   established  to  the  Company's
satisfaction that no such tax or charge is due.

        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
representing  such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer taxes or charges) 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 Company are closed,  such person shall be deemed to have become the
record holder of such shares  (fractional or otherwise) on, and such certificate
shall be dated,  the next succeeding  Business Day on which the Preferred Shares
(or Common Shares and/or other securities, as the case may be) transfer books of
the Company are open. Prior to the exercise of the Rights  represented  thereby,
the  holder of a Right  Certificate  shall not be  entitled  to any  rights of a
holder of Preferred Shares for which the Rights shall be exercisable, including,
without  limitation,  the  right  to  vote  or to  receive  dividends  or  other
distributions,  and  shall  not  be  entitled  to  receive  any  notice  of  any
proceedings of the Company, except as provided herein.

                                       14


     Section 11.  Adjustment  of Purchase  Price,  Number of Shares or Number of
Rights.  The Purchase Price,  the number of Preferred Shares or other securities
or  property  purchasable  upon  exercise of each Right and the number of Rights
outstanding  are  subject to  adjustment  from time to time as  provided in this
Section 11.

                11.1     Post-Execution Events.

                        11.1.1 Corporate Dividends, Reclassifications, Etc. In
                               --------------------------------------------
the event the  Company  shall at any time after the date of this  Agreement  (A)
declare and pay 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 stock in a reclassification of the Preferred Shares (including any
such  reclassification in connection with a consolidation or merger in which the
Company  is the  continuing  or  surviving  corporation),  except  as  otherwise
provided in this Section 11.1,  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 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 stock  which,  if such  Right had been  exercised
immediately  prior to such date and at a time when the Preferred Shares transfer
books of the Company were open,  such person 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 stock of the Company issuable upon exercise
of one Right.  If an event occurs which would require an  adjustment  under both
Sections 11.1.1 and 11.1.2,  the adjustment  provided for in this Section 11.1.1
shall be in  addition  to, and shall be made prior to, the  adjustment  required
pursuant to, Section 11.1.2.

                        11.1.2 Acquiring Person Events; Trigger Events. Subject
                               ----------------------------------------
to Sections 23.1 and Section 27, in the event that a Trigger Event occurs, then,
from and after the  first  occurrence  of such  event,  each  holder of a Right,
except  as  provided  below,  shall  thereafter  have a right to  receive,  upon
exercise thereof at a price per Right equal to the  then-current  Purchase Price
multiplied  by the number of  one-hundredths  of a  Preferred  Share for which a
Right is then  exercisable  (without giving effect to this Section  11.1.2),  in
accordance  with the terms of this  Agreement  and in lieu of Preferred  Shares,
such number of Common Shares per Right as shall equal the result obtained by (x)
multiplying

                                       15


the then-current  Purchase Price by the number of  one-hundredths of a Preferred
Share  for  which a Right is then  exercisable  (without  giving  effect to this
Section  11.1.2) and (y)  dividing  that product by 50% of the Current Per Share
Market Price of the Common Shares  (determined  pursuant to Section 11.4) on the
first  of the  date  of the  occurrence  of,  or the  date of the  first  public
announcement  of, a Trigger Event (the "Adjustment  Shares");  provided that the
Purchase Price and the number of Adjustment  Shares shall  thereafter be subject
to  further   adjustment  as  appropriate  in  accordance   with  Section  11.6.
Notwithstanding  the  foregoing,  upon the  occurrence of a Trigger  Event,  any
Rights that are or have been acquired or beneficially owned by (1) any Acquiring
Person or any Associate or Affiliate thereof,  (2) a transferee of any Acquiring
Person (or of any such  Associate or Affiliate)  who becomes a transferee  after
the Acquiring  Person becomes such, or (3) a transferee of any Acquiring  Person
(or of any such  Associate or  Affiliate)  who becomes a transferee  prior to or
concurrently  with the Acquiring  Person  becoming such and receives such Rights
pursuant to either (A) a transfer  (whether or not for  consideration)  from the
Acquiring  Person to holders of equity  interests in such Acquiring Person or to
any  Person  with  whom  the  Acquiring  Person  has any  continuing  agreement,
arrangement or understanding  regarding the transferred Rights or (B) a transfer
which the Board of Directors  determines  or has  determined  is part of a plan,
arrangement or understanding  which has as a primary purpose or effect avoidance
of this Section 11.1.2, and subsequent  transferees,  shall become null and void
without any  further  action,  and any holder  (whether or not such holder is an
Acquiring  Person or an Associate  or Affiliate of an Acquiring  Person) of such
Rights  shall  thereafter  have no right  to  exercise  such  Rights  under  any
provision of this  Agreement or otherwise.  The Company shall not enter into any
transaction  of the type described in this Section 11.1.2 if at the time of such
transaction   there  are  any  rights,   warrants,   instruments  or  securities
outstanding or any  arrangements  which, as a result of the consummation of such
transaction,  would eliminate or substantially diminish the benefits intended to
be  afforded  by the  Rights.  From  and  after  the  Trigger  Event,  no  Right
Certificate  shall be issued  pursuant to Section 3 or Section 6 that represents
Rights  that  are or  have  become  void  pursuant  to the  provisions  of  this
paragraph,  and  any  Right  Certificate  delivered  to the  Rights  Agent  that
represents  Rights that are or have become void  pursuant to the  provisions  of
this paragraph shall be cancelled.

                                    The Company shall use all reasonable efforts
to ensure that the  provisions  of this Section  11.1.2 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 any Acquiring
Person or its Affiliates, Associates or transferees hereunder.

                                    From and after the occurrence of an event
specified in Section 13.1, any Rights that  theretofore  have not been exercised
pursuant  to  this  Section  11.1.2  shall  thereafter  be  exercisable  only in
accordance with Section 13 and not pursuant to this Section 11.1.2.

                        11.1.3  Insufficient  Shares.  The Company  may  at its
                                ---------------------
option  substitute  for a Common Share  issuable  upon the exercise of Rights in
accordance  with the foregoing  Section  11.1.2 a number of Preferred  Shares or
fraction  thereof such that the Current Per Share Market Price of one  Preferred
Share  multiplied  by such  number or fraction is equal to the Current Per Share
Market Price of one Common Share.  In the event that upon the  occurrence of one
or more of the events

                                       16


listed in Section  11.1.2  above there  shall not be  sufficient  Common  Shares
authorized  but  unissued  to  permit  the  exercise  in full of the  Rights  in
accordance with the foregoing  Section  11.1.2,  the Company shall take all such
action as may be necessary to authorize  additional  Common  Shares for issuance
upon exercise of the Rights,  provided,  however, that if the Company determines
that  it is  unable  to  cause  the  authorization  of a  sufficient  number  of
additional Common Shares, then, in the event the Rights become exercisable,  the
Company, with respect to each Right and to the extent necessary and permitted by
applicable law and any agreements or instruments in effect on the date hereof to
which it is a party,  shall:  (A)  determine  the excess of (1) the value of the
Adjustment  Shares issuable upon the exercise of a Right (the "Current  Value"),
over (2) the Purchase Price (such excess,  the "Spread") and (B) with respect to
each Right  (other  than  Rights  which have  become  void  pursuant  to Section
11.1.2),  make adequate provision to substitute for the Adjustment Shares,  upon
payment of the  applicable  Purchase  Price,  (1) cash,  (2) a reduction  in the
Purchase Price, (3) Preferred  Shares or other equity  securities of the Company
(including,  without  limitation,  shares,  or fractions of shares, of preferred
stock  which,  by virtue of  having  dividend,  voting  and  liquidation  rights
substantially  comparable to those of the Common Shares,  the Board of Directors
has deemed in good faith to have  substantially the same value as Common Shares)
(each such share of preferred  stock or  fractions of shares of preferred  stock
constituting a "Common Stock Equivalent")),  (4) debt securities of the Company,
(5) other assets or (6) any  combination  of the  foregoing  having an aggregate
value equal to the Current Value, where such aggregate value has been determined
by the Board of  Directors  based  upon the  advice of a  nationally  recognized
investment  banking  firm  selected  in good  faith by the  Board of  Directors;
provided, however, that if the Company shall not have made adequate provision to
deliver value pursuant to clause (B) above within thirty (30) days following the
first  occurrence  of a Trigger  Event,  then the Company  shall be obligated to
deliver,  to the  extent  necessary  and  permitted  by  applicable  law and any
agreements or  instruments  in effect on the date hereof to which it is a party,
upon the surrender for exercise of a Right and without  requiring payment of the
Purchase Price,  Common Shares (to the extent available) and then, if necessary,
such number or fractions of Preferred Shares (to the extent available) and then,
if necessary,  cash,  which shares and/or cash have an aggregate  value equal to
the Spread.  If the Board of Directors  shall determine in good faith that it is
unlikely  that  sufficient  additional  Common  Shares could be  authorized  for
issuance  upon  exercise in full of the  Rights,  the thirty (30) day period set
forth above may be extended and  re-extended  to the extent  necessary,  but not
more than ninety (90) days  following the first  occurrence of one of the events
listed in Section 11.1.2 above,  in order that the Company may seek  stockholder
approval for the  authorization of such additional shares (such period as may be
extended, the "Substitution  Period"). To the extent that the Company determines
that some action need be taken pursuant to the second and/or third  sentences of
this Section 11.1.3,  the Company (x) shall provide that such action shall apply
uniformly to all outstanding  Rights,  and (y) may suspend the exercisability of
the Rights until the expiration of the Substitution  Period in order to seek any
authorization  of  additional  shares and/or to decide the  appropriate  form of
distribution  to be made  pursuant to such first  sentence and to determine  the
value thereof.  In the event of any such suspension,  the Company shall promptly
notify the Rights Agent thereof and issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended as well as a public

                                       17


announcement  (with prompt  notice  thereof to the Rights Agent) at such time as
the suspension is no longer in effect.  For purposes of this Section 11.1.3, the
value  of a Common  Share  shall be the  Current  Per  Share  Market  Price  (as
determined  pursuant to Section 11.4) on the date of the occurrence of a Trigger
Event and the value of any "Common Stock Equivalent" shall be deemed to have the
same value as the Common  Shares on such date.  The Board of Directors  may, but
shall not be required to, establish  procedures to allocate the right to receive
Common Shares upon the exercise of the Rights among  holders of Rights  pursuant
to this Section 11.1.3.

                        11.2 Dilutive Rights Offering. In case the Company shall
fix a record date for the issuance of rights, options or warrants to all holders
of Preferred  Shares  entitling them (for a period  expiring  within 45 calendar
days after such record date) to subscribe for or purchase  Preferred  Shares (or
securities  having the same rights,  privileges and preferences as the Preferred
Shares ("Equivalent  Preferred Stock")) or securities convertible into Preferred
Shares or Equivalent Preferred Stock at a price per Preferred Share or per share
of  Equivalent  Preferred  Stock (or having a conversion  or exercise  price per
share, if a security  convertible  into or exercisable  for Preferred  Shares or
Equivalent  Preferred Stock) less than the Current Per Share Market Price of the
Preferred  Shares (as determined  pursuant to Section 11.4) on such record date,
the Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect  immediately  prior to such record date
by a fraction,  the  numerator of which shall be the number of Preferred  Shares
and shares of Equivalent  Preferred  Stock  outstanding on such record date plus
the number of Preferred  Shares and shares of Equivalent  Preferred  Stock which
the  aggregate  offering  price of the total number of Preferred  Shares  and/or
shares of Equivalent Preferred Stock to be offered (and/or the aggregate initial
conversion price of the convertible  securities so to be offered) would purchase
at such Current Per Share Market Price and the denominator of which shall be the
number of Preferred Shares and shares of Equivalent  Preferred Stock outstanding
on such record date plus the number of additional Preferred Shares and/or shares
of Equivalent  Preferred  Stock 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 stock of the Company issuable upon exercise of one Right. In case such
subscription  price may be paid in a consideration part or all of which shall be
in a form  other  than  cash,  the  value  of  such  consideration  shall  be as
determined in good faith by the Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent and shall be conclusive and
binding on the  Rights  Agent and the  holders  of the Rights for all  purposes.
Preferred  Shares and shares of Equivalent  Preferred Stock owned by or held for
the account of the Company or any  Subsidiary of the Company shall not be deemed
outstanding for the purpose of any such  computation.  Such adjustments shall be
made  successively  whenever such a record date is fixed;  and in the event that
such rights or warrants are not so issued,  the Purchase Price shall be adjusted
to be the  Purchase  Price which would then be in effect if such record date had
not been fixed.

                        11.3   Distributions. In  case the  Company shall  fix a
record date for the making of a  distribution  to all  holders of the  Preferred
Shares  (including any such distribution made in connection with a consolidation
or merger in which the

                                       18


Company  is  the   continuing   or  surviving   corporation)   of  evidences  of
indebtedness,   cash,  securities  or  assets  or  convertible  securities,   or
subscription  rights or warrants  (excluding those referred to in Section 11.2),
the Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect  immediately  prior to such record date
by a fraction,  the  numerator  of which  shall be the Current Per Share  Market
Price of the Preferred  Shares (as determined  pursuant to Section 11.4) on such
record  date,  less the fair market  value (as  determined  in good faith by the
Board of Directors,  whose determination shall be described in a statement filed
with the Rights Agent and shall be  conclusive  for all purposes) of the portion
of  the  cash,  assets,  securities  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 (as determined  pursuant to Section 11.4);
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
stock of the Company to be issued upon exercise of one Right.  Such  adjustments
shall be made  successively  whenever  such a record  date is fixed;  and in the
event that such  distribution  is not so made, the Purchase Price shall again be
adjusted to be the  Purchase  Price which would then be in effect if such record
date had not been fixed.

                11.4     Current Per Share Market Value.

                        11.4.1 General. For the purpose of any computation
hereunder,  the "Current Per Share Market  Price" of any security (a  "Security"
for the  purpose of this  Section  11.4.1) on any date shall be deemed to be the
average of the daily  closing  prices per share of such  Security for the thirty
(30) consecutive Trading Days (as such term is hereinafter  defined) immediately
prior to such date;  provided,  however,  that in the event that the Current Per
Share Market Price of the Security is determined during any period following the
announcement by the issuer of such Security of (i) a dividend or distribution on
such Security payable in shares of such Security or securities  convertible into
such shares or (ii) any  subdivision,  combination or  reclassification  of such
Security,  and prior to the expiration of thirty (30)  consecutive  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 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.  If on any
such date no such market maker is making a market in the Security, the fair

                                       19


value of the Security on such date as  determined  in good faith by the Board of
Directors  shall be used.  The term  "Trading Day" shall mean a day on which the
principal  national  securities  exchange  on which  the  Security  is listed or
admitted to trading is open for the  transaction of business or, if the Security
is not listed or  admitted to trading on any  national  securities  exchange,  a
Business  Day. If the Security is not publicly  held or not so listed or traded,
or if on any such date the Security is not so quoted and no such market maker is
making a market in the Security, "Current Per Share Market Price" shall mean the
fair value per share as  determined  in good faith by the Board of Directors or,
if at the  time  of  such  determination  there  is an  Acquiring  Person,  by a
nationally   recognized  investment  banking  firm  selected  by  the  Board  of
Directors,  which shall have the duty to make such determination in a reasonable
and  objective  manner,  whose  determination  shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes.

                        11.4.2 Preferred Shares. Notwithstanding Section 11.4.1,
for the purpose of any  computation  hereunder,  the  "Current  Per Share Market
Price" of the  Preferred  Shares shall be  determined  in the same manner as set
forth above in Section  11.4.1  (other than the last sentence  thereof).  If the
Current Per Share Market Price of the  Preferred  Shares cannot be determined in
the manner described in Section 11.4.1,  the "Current Per Share Market Price" of
the Preferred  Shares shall be conclusively  deemed to be an amount equal to 100
(as such number may be  appropriately  adjusted for such events as stock splits,
stock  dividends  and  recapitalizations  with  respect  to  the  Common  Shares
occurring after the date of this Agreement)  multiplied by the Current Per Share
Market Price of the Common Shares (as determined pursuant to Section 11.4.1). If
neither  the Common  Shares nor the  Preferred  Shares are  publicly  held or so
listed or  traded,  or if on any such date  neither  the  Common  Shares nor the
Preferred  Shares are so quoted and no such  market  maker is making a market in
either the Common  Shares or the  Preferred  Shares,  "Current  Per Share Market
Price" of the Preferred Shares shall mean the fair value per share as determined
in  good  faith  by  the  Board  of  Directors,  or,  if at  the  time  of  such
determination  there  is  an  Acquiring  Person,  by  a  nationally   recognized
investment banking firm selected by the Board of Directors, which shall have the
duty to make such  determination  in a reasonable  and objective  manner,  which
determination  shall be described in a statement filed with the Rights Agent and
shall be  conclusive  for all  purposes.  For  purposes of this  Agreement,  the
"Current Per Share Market Price" of one one-hundredth of a Preferred Share shall
be equal to the "Current Per Share Market Price" of one Preferred  Share divided
by 100.

                        11.5 Insignificant Changes. 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. Any adjustments which
by reason of this  Section  11.5 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-millionth of a Preferred Share or the nearest one ten-thousandth of a Common
Share or other share or security, as the case may be.  Notwithstanding the first
sentence of this Section 11.5, any adjustment  required by this Section 11 shall
be made no later  than  the  earlier  of (i)  three  years  from the date of the
transaction that mandate such adjustment, or (ii) the Expiration Date.

                                       20


                        11.6 Shares Other Than Preferred Shares. If as a result
of an  adjustment  made  pursuant  to  Section  11.1,  the  holder  of any Right
thereafter exercised shall become entitled to receive any shares of stock of the
Company other than Preferred Shares,  thereafter the number of such other shares
so receivable  upon  exercise of any Right shall be subject to  adjustment  from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions  with respect to the  Preferred  Shares  contained in Sections  11.1,
11.2, 11.3, 11.5, 11.8, 11.9 and 11.13, and the provisions of Section 7, Section
9, Section 10,  Section 13 and Section 14 with respect to the  Preferred  Shares
shall apply on like terms to any such other shares.

                        11.7 Rights Issued Prior to Adjustment. All Rights
originally  issued  by the  Company  subsequent  to any  adjustment  made to the
Purchase Price  hereunder  shall include the right to purchase,  at the adjusted
Purchase Price, the number of  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.

                        11.8 Effect of Adjustments. Unless the Company shall
have exercised its election as provided in Section 11.9, upon each adjustment of
the Purchase  Price as a result of the  calculations  made in Sections  11.2 and
11.3, each Right outstanding  immediately prior to the making of such adjustment
shall thereafter include the right to purchase,  at the adjusted Purchase Price,
that number of  one-hundredths  of a Preferred Share  (calculated to the nearest
one-hundred thousandth of a Preferred Share) obtained by (i) multiplying (x) the
number of  one-hundredths  of a Preferred  Share covered by a Right  immediately
prior to this adjustment by (y) the Purchase Price in effect  immediately  prior
to such  adjustment  of the  Purchase  Price and (ii)  dividing  the  product so
obtained by the Purchase Price in effect  immediately  after such  adjustment of
the Purchase Price.

                        11.9 Adjustment in Number of Rights. The Company may
elect on or after the date of any adjustment of the Purchase Price to adjust the
number  of  Rights,  in  substitution  for  any  adjustment  in  the  number  of
one-hundredths  of a Preferred Share issuable 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-hundredths  of a Preferred Share for which a
Right was exercisable  immediately prior to such adjustment.  Each Right held of
record prior to such adjustment of the number of Rights shall become that number
of Rights  (calculated  to the nearest  one-hundredth)  obtained by dividing the
Purchase Price in effect  immediately  prior to adjustment of the Purchase Price
by the Purchase  Price in effect  immediately  after  adjustment of the Purchase
Price.  The Company  shall make a public  announcement  and promptly  notify the
Rights  Agent 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 11.9, the Company may, as promptly
as  practicable,  cause  to  be  distributed  to  holders  of  record  of  Right
Certificates  on such record date Right  Certificates  representing,  subject to
Section 14, the  additional  Rights to which such holders shall be entitled as a
result of such

                                       21


adjustment,  or, at the option of the Company,  shall cause to be distributed to
such  holders  of  record  in   substitution   and  replacement  for  the  Right
Certificates  held by such  holders  prior to the date of  adjustment,  and upon
surrender  thereof,   if  required  by  the  Company,   new  Right  Certificates
representing  all the Rights to which such holders shall be entitled  after such
adjustment.  Right  Certificates so to be distributed shall be issued,  executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company,  the adjusted  Purchase  Price) and shall be  registered  in the
names  of the  holders  of  record  of Right  Certificates  on the  record  date
specified in the public announcement.

                        11.10 Right Certificates Unchanged. Irrespective of any
adjustment or change in the Purchase Price or the number of  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 per
share and the number of one-hundredths of a Preferred Share which were expressed
in the initial Right Certificates issued hereunder.

                        11.11 Par Value Limitations. Before taking any action
that  would  cause  an  adjustment   reducing  the  Purchase   Price  below  one
one-hundredth  of the then par value,  if any, of the Preferred  Shares or other
shares of stock issuable upon exercise of the Rights, the Company shall take any
action which may, in the opinion of its counsel,  be necessary in order that the
Company may validly and  legally  issue fully paid and  nonassessable  Preferred
Shares or other such shares at such adjusted Purchase Price.

                        11.12 Deferred Issuance. In any case in which this
Section  11 shall  require  that an  adjustment  in the  Purchase  Price be made
effective  as of a record date for a specified  event,  the Company may elect to
defer (and shall promptly  notify the Rights Agent of any such  election)  until
the  occurrence of such event the issuance to the holder of any Right  exercised
after such record date of that  number of  Preferred  Shares and shares of other
stock or securities of the Company, if any, issuable upon such exercise over and
above the Preferred Shares and shares of other stock or other securities, assets
or cash of the Company,  if any, issuable upon such exercise on the basis of the
Purchase Price in effect prior to such adjustment;  provided,  however, that the
Company shall deliver to such holder a due bill or other appropriate  instrument
representing  such  holder's  right to receive such  additional  shares upon the
occurrence of the event requiring such adjustment.

                        11.13 Reduction in Purchase Price. Anything in this
Section 11 to the  contrary  notwithstanding,  the Company  shall be entitled to
make such  reductions in the Purchase  Price,  in addition to those  adjustments
expressly  required by this Section 11, as and to the extent that it in its sole
discretion  shall determine to be advisable in order that any  consolidation  or
subdivision  of the  Preferred  Shares,  issuance  wholly for cash of any of the
Preferred Shares at less than the current market price, issuance wholly for cash
of Preferred  Shares or securities  which by their terms are convertible into or
exchangeable  for Preferred  Shares,  dividends on Preferred  Shares  payable in
Preferred Shares or issuance of rights, options or warrants referred to above in
this  Section  11,  hereafter  made by the  Company to holders of its  Preferred
Shares, shall not be taxable to such stockholders.

                                       22


                        11.14 Company Not to Diminish Benefits of Rights. The
Company  covenants  and agrees that after the earlier of the Shares  Acquisition
Date or  Distribution  Date it will not,  except as  permitted  by  Section  23,
Section 26 or Section 27, take (or permit any  Subsidiary to take) any action if
at the time such action is taken it is reasonably  foreseeable  that such action
will substantially  diminish or otherwise  eliminate the benefits intended to be
afforded by the Rights.

                        11.15 Adjustment of Rights Associated with Common
Shares. Notwithstanding anything contained in this Agreement to the contrary, in
the event that the Company  shall at any time after the date hereof and prior to
the Distribution Date (i) declare or pay any dividend on the outstanding  Common
Shares payable in Common Shares,  (ii) effect a subdivision or  consolidation of
the  outstanding  Common Shares (by  reclassification  or otherwise  than by the
payment of dividends payable in Common Shares), or (iii) combine the outstanding
Common Shares into a greater or lesser number of Common Shares, then in any such
case, the number of Rights  associated with each Common Share then  outstanding,
or issued or  delivered  thereafter  but  prior to the  Distribution  Date or in
accordance with Section 22 shall be proportionately  adjusted so that the number
of Rights thereafter  associated with each Common Share following any such event
shall equal the result obtained by multiplying  the number of Rights  associated
with each  Common  Share  immediately  prior to such  event by a  fraction,  the
numerator  of which  shall be the  total  number of  Common  Shares  outstanding
immediately  prior to the  occurrence of the event and the  denominator of which
shall be the total number of Common Shares outstanding immediately following the
occurrence  of such event.  The  adjustment  provided for in this Section  11.15
shall be made successively whenever a dividend referred to in this Section 11.15
is declared or paid or a subdivision,  combination or consolidation  referred to
in this Section 11.15 is effected.

                        11.16 Company Agreements. The Company covenants and
agrees  that it shall not, at any time after the  Distribution  Date engage in a
Transaction if (x) at the time of or immediately  after such  Transaction  there
are any rights,  warrants or other  instruments  or  securities  outstanding  or
agreements in effect that would  substantially  diminish or otherwise  eliminate
the  benefits   intended  to  be  afforded  by  the  Rights  or  (y)  prior  to,
simultaneously  with or immediately after such Transaction,  the stockholders of
the Person who  constitutes,  or would  constitute,  the  "Principal  Party" for
purposes of Section 13.1 hereof  shall have  received a  distribution  of Rights
previously owned by such Person or any of its Affiliates and Associates.

     Section 12.  Certificate  of Adjusted  Purchase  Price or Number of Shares.
Whenever  an  adjustment  is made as  provided  in Section 11 or Section 13, the
Company shall (a) promptly prepare a certificate  setting forth such adjustment,
and a  brief  statement  of the  facts  and  computations  accounting  for  such
adjustment, (b) promptly file with the Rights Agent and with each transfer agent
for the Common Shares or the Preferred Shares a copy of such certificate and (c)
mail a brief summary thereof to each holder of a Right Certificate in accordance
with  Section 25. The Rights  Agent shall be fully  protected  in relying on any
such certificate and on any adjustment  therein contained and shall have no duty
with respect to and shall not be deemed to have knowledge of any such adjustment
unless and until it shall have received such certificate.

                                       23


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

                13.1  Certain Transactions.  In the event that, from and after
the first  occurrence of a Trigger Event,  directly or  indirectly,  the Company
consummates a Transaction,  then, and in each such case,  proper provision shall
be made so that

                        (i)      each holder of a Right (other than Rights which
     have become void  pursuant to Section  11.1.2)  shall  thereafter  have the
     right to receive,  upon the exercise  thereof at a price per Right equal to
     the then-current  Purchase Price multiplied by the number of one-hundredths
     of a Preferred Share for which a Right was exercisable immediately prior to
     the first occurrence of a Trigger Event (as subsequently  adjusted pursuant
     to Sections 11.1.1,  11.2, 11.3, 11.8, 11.9 and 11.12),  in accordance with
     the  terms of this  Agreement  and in lieu of  Preferred  Shares  or Common
     Shares,  such  number  of  validly  authorized  and  issued,   fully  paid,
     non-assessable and freely tradable Common Shares of the Principal Party (as
     such term is hereinafter  defined) not subject to any liens,  encumbrances,
     rights of first refusal or other adverse  claims,  as shall be equal to the
     result obtained by (x) multiplying the  then-current  Purchase Price by the
     number  of  one-hundredths  of a  Preferred  Share  for  which a Right  was
     exercisable  immediately  prior to the first  occurrence of a Trigger Event
     (as subsequently  adjusted  pursuant to Sections 11.1.1,  11.2, 11.3, 11.8,
     11.9 and 11.12) and (y)  dividing  that  product by 50% of the then Current
     Per  Share  Market  Price of the  Common  Shares  of such  Principal  Party
     (determined  pursuant to Section 11.4) on the date of  consummation  of the
     Transaction;  provided,  that the price per Right so payable and the number
     of Common Shares of such Principal  Party so receivable  upon exercise of a
     Right shall  thereafter be subject to further  adjustment as appropriate in
     accordance  with  Section  11.6  to  reflect  any  events  covered  thereby
     occurring in respect of the Common Shares of such Principal Party after the
     occurrence of such consolidation, merger, sale or transfer;

                        (ii)     such Principal Party shall thereafter be liable
     for, and shall assume,  by virtue of such  consolidation,  merger,  sale or
     transfer,  all the obligations  and duties of the Company  pursuant to this
     Agreement;

                        (iii)    the term "Company" shall thereafter be deemed
     to refer to such Principal Party; and

                        (iv)     such Principal Party shall take such steps
     (including,  but not limited to, the  authorization  and  reservation  of a
     sufficient  number of its Common  Shares in  accordance  with Section 9) in
     connection  with such  consummation  as may be necessary to assure that the
     provisions  hereof shall thereafter be applicable,  as nearly as reasonably
     may be, in relation to its Common Shares  thereafter  deliverable  upon the
     exercise of the Rights;  provided that,  upon the subsequent  occurrence of
     any   consolidation,   merger,   sale  or   transfer  of  assets  or  other

                                       24


     extraordinary  transaction in respect of such Principal Party,  each holder
     of a Right shall thereupon be entitled to receive, upon exercise of a Right
     and payment of the Purchase  Price as provided in this Section  13.1,  such
     cash, shares,  rights,  warrants and other property which such holder would
     have  been  entitled  to  receive  had  such  holder,  at the  time of such
     transaction, owned the Common Shares of the Principal Party receivable upon
     the exercise of a Right  pursuant to this Section 13.1,  and such Principal
     Party shall take such steps (including,  but not limited to, reservation of
     shares of stock) as may be necessary to permit the  subsequent  exercise of
     the Rights in  accordance  with the terms  hereof  for such  cash,  shares,
     rights, warrants and other property.

                13.2 The Company shall not consummate any Transaction unless
prior  thereto the  Company and such  Principal  Party shall have  executed  and
delivered  to the Rights  Agent a  supplemental  agreement  confirming  that the
requirements  of this  Sections  13.1 and 13.2 shall  promptly be  performed  in
accordance  with  their  terms and that such  Transaction  shall not result in a
default by the Principal  Party under this Agreement as the same shall have been
assumed by the  Principal  Party  pursuant to this Section 13.1 and Section 13.2
and providing  that,  as soon as  practicable  after  executing  such  agreement
pursuant to this Section 13, the Principal Party, at its own expense, shall

                        (i) prepare  and file a  registration  statement  under
     the  Securities  Act,  if  necessary,  with  respect  to the Rights and the
     securities  purchasable upon exercise of the Rights on an appropriate form,
     use its best  efforts  to  cause  such  registration  statement  to  become
     effective as soon as practicable after such filing and use its best efforts
     to cause such registration statement to remain effective (with a prospectus
     at all times  meeting the  requirements  of the  Securities  Act) until the
     Expiration Date and similarly comply with applicable state securities laws;

                        (ii)     use its best efforts, if the Common Shares of
     the Principal  Party shall be listed or admitted to trading on the New York
     Stock Exchange or on another national securities exchange, to list or admit
     to trading  (or  continue  the  listing  of) the Rights and the  securities
     purchasable  upon exercise of the Rights on the New York Stock  Exchange or
     such securities  exchange,  or, if the Common Shares of the Principal Party
     shall not be listed or admitted  to trading on the New York Stock  Exchange
     or a national securities  exchange,  to cause the Rights and the securities
     receivable  upon exercise of the Rights to be  authorized  for quotation on
     Nasdaq or on such other system then in use;

                        (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 (or any successor form)
     under the Exchange Act; and

                        (iv)     obtain waivers of any rights of first refusal
     or preemptive rights in respect of the Common Shares of the Principal Party
     subject to purchase upon exercise of outstanding Rights.

                                       25


                           In case the Principal Party has provision in any of
its  authorized  securities  or in its  charter  or bylaws  or other  instrument
governing its corporate  affairs,  which  provision would have the effect of (i)
causing such Principal  Party to issue (other than to holders of Rights pursuant
to  this  Section  13),  in  connection  with,  or  as  a  consequence  of,  the
consummation  of a transaction  referred to in this Section 13, Common Shares or
Common Stock  Equivalents of such Principal Party at less than the  then-current
market  price  per  share  thereof  (determined  pursuant  to  Section  11.4) or
securities  exercisable for, or convertible  into, Common Shares or Common Stock
Equivalents of such Principal Party at less than such then-current  market price
(other than to holders of Rights pursuant to this Section 13), or (ii) providing
for any special  payment,  taxes or similar  provision  in  connection  with the
issuance of the Common Shares of such Principal  Party pursuant to the provision
of Section 13, then, in such event,  the Company  hereby agrees with each holder
of Rights that it shall not consummate any such transaction unless prior thereto
the Company and such  Principal  Party shall have  executed and delivered to the
Rights Agent a supplemental  agreement  providing that the provision in question
of such Principal  Party shall have been cancelled,  waived or amended,  or that
the authorized  securities shall be redeemed,  so that the applicable  provision
will have no effect in connection with, or as a consequence of, the consummation
of the proposed transaction.

                           The Company covenants and agrees that it shall not,
at any time after the Trigger  Event,  enter into any  Transaction if (i) at the
time of or immediately after such Transaction there are any rights,  warrants or
other instruments or securities  outstanding or agreements in effect which would
substantially  diminish  or  otherwise  eliminate  the  benefits  intended to be
afforded by the Rights, (ii) prior to,  simultaneously with or immediately after
such  Transaction,  the  stockholders  of the Person who  constitutes,  or would
constitute, the Principal Party for purposes of Section 13.3 shall have received
a  distribution  of  Rights  previously  owned  by  such  Person  or  any of its
Affiliates  or  Associates  or (iii) the form or nature of  organization  of the
Principal Party would preclude or limit the  exercisability  of the Rights.  The
provisions of this Section 13 shall similarly apply to successive Transactions.

                13.3     Principal Party.  "Principal Party" shall mean:

                        (i)      in the case of any Transaction: (i) the Person
     that is the  issuer of the  securities  into  which the  Common  Shares are
     converted in such  Transaction,  or, if there is more than one such issuer,
     the issuer the Common  Shares of which have the greatest  aggregate  market
     value of shares  outstanding,  or (ii) if no securities are so issued,  (x)
     the Person that is the other party to the merger,  if such Person  survives
     said  merger,  or, if there is more than one such  Person,  the  Person the
     Common Shares of which have the greatest  aggregate  market value of shares
     outstanding or (y) if the Person that is the other party to the merger does
     not survive the merger,  the Person that does survive the merger (including
     the  Company  if  it  survives)  or  (z)  the  Person  resulting  from  the
     consolidation; and

                                       26


                        (ii)     in the case of any Transaction, the Person that
     is the party receiving the greatest  portion of the assets or earning power
     transferred  pursuant  to such  transaction  or  transactions,  or, if each
     Person that is a party to such Transaction receives the same portion of the
     assets or  earning  power so  transferred  or if the Person  receiving  the
     greatest  portion  of the  assets or earning  power  cannot be  determined,
     whichever  of such  Persons  is the  issuer of  Common  Shares  having  the
     greatest aggregate market value of shares outstanding;  provided,  however,
     that in any  Transaction,  if the Common  Shares of such  Person are not at
     such time or have not been  continuously  over the  preceding  twelve month
     period  registered  under  Section 12 of the Exchange Act, then (1) if such
     Person is a direct or  indirect  Subsidiary  of  another  Person the Common
     Shares of which are and have been so registered, the term "Principal Party"
     shall refer to such other  Person,  or (2) if such Person is a  Subsidiary,
     directly or indirectly,  of more than one Person,  the Common Shares of all
     of which are and have been so registered,  the term "Principal Party" shall
     refer to whichever of such  Persons is the issuer of Common  Shares  having
     the greatest aggregate market value of shares  outstanding,  or (3) if 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 clauses  (1) and (2) above  shall  apply to
     each of the owners having an interest in the venture as if the Person owned
     by the  joint  venture  was a  Subsidiary  of  both  or all of  such  joint
     venturers,  and the  Principal  Party  in each  such  case  shall  bear the
     obligations  set forth in this Section 13 in the same ratio as its interest
     in such Person bears to the total of such interests.

                13.4 Approved Acquisitions. Notwithstanding anything contained
herein  to the  contrary,  in the  event  of any  merger  or  other  acquisition
transaction  involving  the Company  pursuant  to a merger or other  acquisition
agreement  between the  Company and any Person (or one or more of such  Person's
Affiliates  or  Associates)  which  agreement  has been approved by the Board of
Directors prior to any Person becoming an Acquiring  Person,  this Agreement and
the rights of holders of Rights hereunder shall be terminated in accordance with
Section 7.1.

        Section 14.       Fractional Rights and Fractional Shares.

                14.1 Cash in Lieu of Fractional Rights. The Company shall not be
required to issue fractions of Rights or to distribute Right  Certificates which
represent fractional Rights (except prior to the Distribution Date in accordance
with Section 11.15). 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  14.1,  the  current  market  value of a whole  Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such  fractional  Rights would have been otherwise  issuable.  The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day,  the average of the closing bid and asked  prices,
regular  way,  in  either  case  as  reported  in  the  principal   consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading  on the New York  Stock  Exchange  or, if the  Rights  are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated  transaction  reporting system with respect to securities listed on
the  principal  national  securities  exchange on which the Rights are listed or
admitted to trading or, if the Rights are not listed or admitted to trading on

                                       27


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.  If on any such date no such
market maker is making a market in the Rights,  the current  market value of the
Rights on such date shall be the fair value of the Rights as  determined in good
faith by the Board of Directors,  or, if at the time of such determination there
is an Acquiring  Person,  by a  nationally  recognized  investment  banking firm
selected  by the  Board of  Directors,  which  shall  have the duty to make such
determination in a reasonable and objective manner, which determination shall be
described in a statement filed with the Rights Agent and shall be conclusive for
all purposes.

                14.2 Cash in Lieu of Fractional Preferred Shares. The Company
shall not be  required  to issue  fractions  of  Preferred  Shares  (other  than
fractions  which are  integral  multiples  of one  one-hundredth  of a Preferred
Share) upon  exercise or  exchange of the Rights or to  distribute  certificates
which  represent  fractional  Preferred  Shares (other than fractions  which are
integral  multiples of one  one-hundredth  of a Preferred  Share).  Interests in
fractions of Preferred  Shares in integral  multiples of one  one-hundredth of a
Preferred  Share  may,  at  the  election  of the  Company,  be  represented  by
depositary  receipts,  pursuant to an appropriate  agreement between the Company
and a depositary  selected by it;  provided,  that such agreement  shall provide
that  the  holders  of such  depositary  receipts  shall  have  all the  rights,
privileges and  preferences  to which they are entitled as beneficial  owners of
the  Preferred  Shares  represented  by  such  depositary  receipts.  In lieu of
fractional Preferred Shares that are not integral multiples of one one-hundredth
of a Preferred Share,  the Company shall pay to the registered  holders of Right
Certificates  at the time such  Rights  are  exercised  or  exchanged  as herein
provided  an amount in cash equal to the same  fraction of the Current Per Share
Market Price of one Preferred  Share (as  determined in accordance  with Section
11.4) for the  Trading  Day  immediately  prior to the date of such  exercise or
exchange.

                14.3 Cash in Lieu of Fractional Common Shares. The Company shall
not  be  required  to  issue   fractions  of  Common  Shares  or  to  distribute
certificates  which  represent  fractional  Common  Shares upon the  exercise or
exchange of Rights. In lieu of such fractional Common Shares,  the Company shall
pay to the  registered  holders of the Right  Certificates  with regard to which
such  fractional  Common  Shares  would  otherwise be issuable an amount in cash
equal to the same  fraction of the current  market value of a whole Common Share
(as determined in accordance  with Section 14.1) for the Trading Day immediately
prior to the date of such exercise or exchange.

                14.4 Waiver of Right to Receive Fractional Rights or Shares. The
holder of a Right by the acceptance of the Rights  expressly waives his right to
receive any fractional Rights or any fractional shares upon exercise or exchange
of a Right, except as permitted by this Section 14.

                                       28


     Section  15.  Rights of  Action.  All  rights of action in  respect of this
Agreement,  except the rights of action given to the Rights Agent hereunder, are
vested in the  respective  registered  holders of the Right  Certificates  (and,
prior to the  Distribution  Date, the registered  holders of the Common Shares);
and  any  registered   holder  of  any  Right  Certificate  (or,  prior  to  the
Distribution  Date,  of the Common  Shares),  without  the consent of the Rights
Agent  or of the  holder  of any  other  Right  Certificate  (or,  prior  to the
Distribution Date, of the Common Shares), may, in his own behalf and for his own
benefit, enforce this Agreement, and may institute and maintain any suit, action
or  proceeding  against  the Company to enforce  this  Agreement,  or  otherwise
enforce or act in respect of his right to  exercise  the Rights  represented  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
shall  be  entitled  to  specific  performance  of the  obligations  under,  and
injunctive relief against actual or threatened violations of, the obligations of
any  Person  (including,  without  limitation,  the  Company)  subject  to  this
Agreement.

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

                        (i)      prior to the Distribution Date, the Rights will
     be transferable only in connection with the transfer of the Common Shares;

                        (ii)     as of and after the Distribution Date, the
     Right  Certificates  are  transferable  only on the  registry  books of the
     Rights Agent if  surrendered  at the office of the Rights Agent  designated
     for such purpose,  duly endorsed or accompanied  by a proper  instrument of
     transfer with all required certifications completed; and

                        (iii)    the Company and the Rights Agent may deem and
     treat the  Person in whose  name the Right  Certificate  (or,  prior to the
     Distribution Date, the associated Common Shares  certificate) is registered
     as  the  absolute  owner  thereof  and  of the  Rights  represented  hereby
     (notwithstanding  any  notations  of  ownership  or  writing  on the  Right
     Certificates  or the associated  Common Shares  certificate  made by anyone
     other than the Company or the Rights  Agent) for all  purposes  whatsoever,
     and  neither  the  Company  nor the Rights  Agent  shall be affected by any
     notice to the contrary.

     Section 17. Right Certificate  Holder Not Deemed a Stockholder.  No holder,
as such, of any Right Certificate  shall be entitled to vote,  receive dividends
or be deemed for any  purpose  the holder of the  Preferred  Shares or any other
securities  of the Company  which may at any time be issuable on the exercise of
the Rights  represented  thereby,  nor shall anything contained herein or in any
Right  Certificate  be  construed  to  confer  upon  the  holder  of  any  Right
Certificate,  as such,  any of the rights of a stockholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
stockholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
stockholders  (except as provided in Section  24),  or to receive  dividends  or
subscription rights, or otherwise, until the Right or Rights represented by such
Right  Certificate  shall have been exercised in accordance  with the provisions
hereof.

                                       29


     Section 18.  Concerning the Rights Agent.  The Company agrees to pay to the
Rights Agent reasonable  compensation for all services  rendered by it hereunder
in accordance with the fee schedule  attached hereto as Exhibit D and, from time
to time, on demand of the Rights Agent, its reasonable expenses and counsel fees
and  other  disbursements  incurred  in the  preparation,  execution,  delivery,
administration  and amendment of this Agreement and the exercise and performance
of its duties  hereunder.  The Company also agrees to indemnify the Rights Agent
for, and to hold it harmless against,  any loss,  liability,  damage,  judgment,
fine, penalty,  claim, demand,  settlement,  cost, or expense,  incurred without
gross  negligence,  bad faith or  willful  misconduct  on the part of the Rights
Agent,  as finally  determined  by a court of  competent  jurisdiction,  for any
action taken,  suffered,  or omitted by the Rights Agent in connection  with the
acceptance  and  administration  of this  Agreement,  including  the  costs  and
expenses of defending against any claim of liability arising therefrom, directly
or indirectly.  The costs and expenses incurred by the Rights Agent in enforcing
this right of indemnification  shall be paid by the Company unless it is finally
determined  by a court of  competent  jurisdiction  that the Rights Agent is not
entitled to  indemnification  due to the Rights  Agent's gross  negligence,  bad
faith or willful  misconduct,  in which event,  the Rights Agent shall repay all
such costs and expenses.  The indemnity and  compensation  provided herein shall
survive the termination of this Agreement, the termination and the expiration of
the Rights and the  resignation or removal of the Rights Agent.  Anything to the
contrary  notwithstanding,  in no event  shall the  Rights  Agent be liable  for
special, punitive,  indirect,  consequential or incidental loss or damage of any
kind whatsoever (including but not limited to lost profits),  even if the Rights
Agent has been advised of the  likelihood of such loss or damage.  Any liability
of the Rights Agent under this Rights Agreement will be limited to the amount of
fees paid by the Company to the Rights Agent pursuant to 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 the Preferred  Shares or the Common Shares or for
other securities of the Company,  instrument of assignment or transfer, power of
attorney,  endorsement,   affidavit,  letter,  notice,  instruction,  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,  limited  liability  company or other  Person into which the Rights
Agent or any  successor  Rights  Agent  may be  merged  or with  which it may be
consolidated,  or any  corporation,  limited  liability  company or other Person
resulting  from any merger or  consolidation  to which the  Rights  Agent or any
successor Rights Agent shall be a party, or any corporation,  limited  liability
company or other  Person  succeeding  to the 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

                                       30


part of any of the  parties  hereto,  provided  that such  corporation,  limited
liability  company  or other  Person  would be  eligible  for  appointment  as a
successor  Rights Agent under the  provisions of Section 21. In case at the time
such  successor  Rights  Agent  shall  succeed  to the  agency  created  by this
Agreement,  any of the Right  Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the
predecessor  Rights Agent and deliver such Right  Certificates so countersigned;
and in case at that  time any of the  Right  Certificates  shall  not have  been
countersigned,   any  successor   Rights  Agent  may   countersign   such  Right
Certificates  either in the name of the predecessor  Rights Agent or in the name
of the  successor  Rights Agent;  and in all such cases such Right  Certificates
shall  have  the full  force  provided  in the  Right  Certificates  and in this
Agreement.

                  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 the
duties  and  obligations  expressly  imposed by this  Agreement  (and no implied
duties or  obligations)  upon the terms and conditions set forth in this Section
20, by all of which the Company and the holders of Right Certificates,  by their
acceptance thereof, shall be bound.

                20.1 Legal Counsel. The Rights Agent may consult with legal
counsel  selected  by it (who may be legal  counsel  for the  Company),  and the
written   advice  or  opinion  of  such  counsel  shall  be  full  and  complete
authorization  and  protection to the Rights  Agent,  and the Rights Agent shall
incur no liability for or the respect of any action taken,  suffered, or omitted
by it in good faith and in accordance with such written advice or opinion.

                20.2 Certificates as to Facts or Matters. Whenever in the
performance  of its duties under this  Agreement  the Rights Agent shall deem it
necessary or desirable  that any fact or matter be proved or  established by the
Company prior to taking or suffering any action  hereunder,  such fact or matter
(unless  other   representation  in  respect  thereof  be  herein   specifically
prescribed)  may be  deemed  to be  conclusively  proved  and  established  by a
certificate  signed by any one of the  Chairman of the Board of  Directors,  the
Chief Executive Officer,  the Chief Financial Officer,  any Vice President,  the
Treasurer,  the Secretary or any Assistant  Treasurer or Assistant  Secretary of
the Company and delivered to the Rights  Agent;  and such  certificate  shall be
full  authorization  and  protection to the Rights  Agent,  and the Rights Agent
shall  incur no  liability  for or in respect of any action  taken,  suffered or
omitted in good faith by it under the  provisions of this  Agreement in reliance
upon such certificate.

                20.3 Standard of Care. The Rights Agent shall be liable
hereunder only for its own gross negligence,  bad faith or willful misconduct as
finally determined by a court of competent jurisdiction.

                                       31


                20.4 Reliance on Agreement and Right Certificates. 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 as to
its  countersignature  thereof) or be required to verify the same,  but all such
statements and recitals are and shall be deemed to have been made by the Company
only.

                20.5 No Responsibility as to Certain Matters. The Rights Agent
shall not have any liability for, nor 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 liable or responsible  for any breach by the Company of any covenant
or condition contained in this Agreement or in any Right Certificate;  nor shall
it be liable or responsible for any change in the  exercisability  of the Rights
(including  the  Rights  becoming  void  pursuant  to  Section  11.1.2)  or  any
adjustment  required  under the provisions of Section 3, Section 11, Section 13,
Section 23 or Section 27 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  represented
by Right Certificates after actual notice of any such change or adjustment); 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  other
securities to be issued  pursuant to this Agreement or any Right  Certificate or
as to whether any Preferred Shares will, when so issued,  be validly  authorized
and issued, fully paid and nonassessable.

                20.6 Further Assurance by Company. The Company agrees that it
will  perform,  execute,  acknowledge  and  deliver  or cause  to be  performed,
executed,   acknowledged   and  delivered  all  such  further  and  other  acts,
instruments and assurances as may reasonably be required by the Rights Agent for
the carrying out or  performing  by the Rights Agent of the  provisions  of this
Agreement.

                20.7 Authorized Company Officers. The Rights Agent is hereby
authorized and directed to accept  instructions  with respect to the performance
of its duties  hereunder from any one of the Chairman of the Board of Directors,
the Chief Executive Officer,  the Chief Financial  Officer,  any Vice President,
the Treasurer,  the Secretary or any Assistant  Treasurer or Assistant Secretary
of the  Company,  and to apply to such  officers for advice or  instructions  in
connection with its duties under this Agreement, and such advice or instructions
shall be full  authorization  and  protection to the Rights Agent and the Rights
Agent  shall  incur no  liability  for or the  respect  of any  action  taken or
suffered  to be taken or  omitted  by it in good  faith in  accordance  with the
advice or  instructions  of any such  officer  or for any delay in acting  while
waiting for these instructions.

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

                                       32


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

                20.10   Incomplete Certificate. If,  with respect to  any Rights
Certificate  surrendered  to the Rights  Agent for  exercise  or  transfer,  the
certificate  contained  in the form of  assignment  or the form of  election  to
purchase  set forth on the  reverse  thereof,  as the case may be,  has not been
completed to certify the holder is not an  Acquiring  Person (or an Affiliate or
Associate  thereof),  the Rights  Agent shall not take any  further  action with
respect to such requested exercise or transfer without first consulting with the
Company.

                20.11   Rights Holders  List. At any  time and from time to time
after the Distribution  Date, upon the request of the Company,  the Rights Agent
shall promptly deliver to the Company a list, as of the most recent  practicable
date (or as of such earlier date as may be  specified  by the  Company),  of the
holders of record of Rights.

                20.12 Use of Funds. 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 it believes  that  repayment of such funds or adequate
indemnification against such risk or liability is not assured to it.

     Section  21.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon  thirty  (30) days'  notice in writing  mailed to the  Company  and to each
transfer agent of the Common Shares and/or Preferred Shares,  as applicable,  by
registered or certified mail. Following the Distribution Date, the Company shall
promptly notify the holders of the Right Certificates by first-class mail of any
such  resignation.  The  Company  may remove the Rights  Agent or any  successor
Rights  Agent upon  thirty (30) days'  notice in  writing,  mailed to the Rights
Agent or successor  Rights Agent, as the case may be, and to each transfer agent
of the Common Shares and/or Preferred  Shares,  as applicable,  by registered or
certified  mail,  and to the holders of the Right  Certificates  by  first-class
mail. If the Rights Agent shall resign or be removed or shall  otherwise  become
incapable of acting, the resigning, removed, or incapacitated Rights Agent shall
remit  to the  Company,  or to any  successor  Rights  Agent  designated  by the
Company,  all  books,  records,  funds,   certificates  or  other  documents  or
instruments  of any kind then in its  possession  which  were  acquired  by such
resigning, removed or incapacitated Rights Agent in connection with its services
as Rights Agent  hereunder,  and shall  thereafter be discharged from all duties
and  obligations  hereunder.  Following  notice of such removal,  resignation or
incapacity, the

                                       33


Company  shall  appoint a successor to such Rights  Agent.  If the Company shall
fail to make such  appointment  within a period of thirty (30) days after giving
notice  of such  removal  or after  it has  been  notified  in  writing  of such
resignation or incapacity by the resigning or  incapacitated  Rights Agent or by
the holder of a Right Certificate (who shall, with such notice, submit his Right
Certificate  for inspection by the Company),  then the registered  holder of any
Right  Certificate  may apply to any  court of  competent  jurisdiction  for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the  Company  or by such a  court,  shall  be a Person  organized  and  doing
business  under the laws of the United  States or of the State of New York,  the
State of  California  or the State of Delaware (or any other state of the United
States so long as such Person is  authorized  to do business in the State of New
York, California or Delaware) in good standing, having an office in the State of
New York, the State of California or the State of Delaware,  which is authorized
under such laws to exercise  stockholder  services and is subject to supervision
or  examination  by Federal or state  authority and which has at the time of its
appointment  as Rights  Agent a  combined  capital  and  surplus of at least $50
million. After appointment,  the successor Rights Agent shall be vested with the
same powers,  rights,  duties and  responsibilities as if it had been originally
named as Rights Agent without  further act or deed; but the  predecessor  Rights
Agent shall deliver and transfer to the  successor  Rights Agent any property at
the time held by it  hereunder,  and execute and deliver any further  assurance,
conveyance,  act or deed necessary for the purpose. Not later than the effective
date of any such  appointment  the Company shall file notice  thereof in writing
with the  predecessor  Rights Agent and each transfer agent of the Common Shares
and/or Preferred Shares, as applicable,  and,  following the Distribution  Date,
mail a  notice  thereof  in  writing  to the  registered  holders  of the  Right
Certificates.  Failure  to give any  notice  provided  for in this  Section  21,
however, or any defect therein, shall not affect the legality or validity of the
resignation  or removal of the Rights Agent or the  appointment of the successor
Rights Agent, as the case may be.

     Section 22. Issuance of New Right Certificates.  Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary,  the Company may,
at its option, issue new Right Certificates  representing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Right Certificates made in accordance with the
provisions of this  Agreement.  In addition,  in connection with the issuance or
sale  of  Common  Shares  following  the  Distribution  Date  and  prior  to the
Expiration  Date, the Company shall,  with respect to Common Shares so issued or
sold  pursuant to the exercise of stock  options or under any  employee  plan or
arrangement,  granted or awarded,  or upon  exercise,  conversion or exchange of
securities (other than Common Shares) hereinafter issued by the Company, in each
case  existing  prior  to  the  Distribution   Date,  issue  Right  Certificates
representing  the appropriate  number of Rights in connection with such issuance
or sale; provided,  however,  that (i) no such Right Certificate shall be issued
if, and to the extent  that,  the Company  shall be advised by counsel that such
issuance would create a significant risk of material adverse tax consequences to
the Company or the Person to whom such Right  Certificate  would be issued,  and
(ii) no such Right  Certificate  shall be issued  if,  and to the  extent  that,
appropriate  adjustment  shall  otherwise have been made in lieu of the issuance
thereof.

                                       34


     Section 23.       Redemption.

                23.1 Right to Redeem. The Company may, at its option, at any
time prior to earlier of the Trigger Event and the Expiration  Date,  redeem all
but not less than all of the then  outstanding  Rights at a redemption  price of
$.001 per Right,  appropriately  adjusted  to  reflect  any stock  split,  stock
dividend,  recapitalization  or  similar  transaction  occurring  after the date
hereof (such redemption price being  hereinafter  referred to as the "Redemption
Price"),  and the Company may, at its option, pay the Redemption Price in Common
Shares  (based on the "Current Per Share Market  Price"  determined  pursuant to
Section 11.4 of the Common Shares at the time of redemption),  cash or any other
form  of  consideration  deemed  appropriate  by the  Board  of  Directors.  The
redemption  of the Rights by the Company may be made  effective at such time, on
such basis and subject to such  conditions as the Board of Directors in its sole
discretion may establish.

                23.2 Redemption Procedures. Immediately upon the action of the
Board of Directors  ordering the redemption of the Rights (or at such later time
as  the  Board  of  Directors  may  establish  for  the  effectiveness  of  such
redemption), 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. The
Company shall  promptly  give the Rights Agent prompt notice  thereof and public
notice of such redemption;  provided,  however, that the failure to give, or any
defect in, any such notice shall not affect the validity of such redemption. The
Company shall promptly  give, or cause the Rights Agent to give,  notice of such
redemption to the holders of the then outstanding  Rights by mailing such notice
to all such  holders at their last  addresses  as they appear upon the  registry
books of the Rights Agent or, prior to the  Distribution  Date,  on the registry
books of the transfer agent for the Common 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  shall state the method by
which the payment of the Redemption Price will be made.  Neither the Company nor
any of its  Affiliates or Associates  may redeem,  acquire or purchase for value
any Rights at any time in any manner other than that  specifically  set forth in
this  Section  23 or in  Section  27,  and  other  than in  connection  with the
purchase,  acquisition or redemption of Common Shares prior to the  Distribution
Date.

                Section 24. Notice of Certain Events. In case the Company shall
propose at any time after the  earlier  of the Shares  Acquisition  Date and the
Distribution  Date (a) to pay any dividend  payable in stock of any class to the
holders of Preferred Shares or to make any other  distribution to the holders of
Preferred  Shares,  or (b) to offer to the holders of 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, or (c)
to  effect  any   reclassification   of  its  Preferred  Shares  (other  than  a
reclassification   involving  only  the  subdivision  of  outstanding  Preferred
Shares), or (d) to effect any consolidation or merger into or with, or to effect
any sale or other  transfer  (or to permit  one or more of its  Subsidiaries  to
effect any sale or other transfer), in one or more transactions,  of 50% or more
of the assets or earning power of the Company and its  Subsidiaries  (taken as a
whole)  to,  any  other  Person  (other  than  pursuant  to a  merger  or  other
acquisition agreement of the type described in Section 1.3(ii)(A)(z)), or (e) to
effect the liquidation,

                                       35


dissolution or winding up of the Company,  or (f) to declare or pay any dividend
on the  Common  Shares  payable  in Common  Shares  or to effect a  subdivision,
combination  or  consolidation  of the  Common  Shares (by  reclassification  or
otherwise  than by payment of dividends in Common  Shares),  then,  in each such
case,  the Company  shall give to the Rights Agent and to each holder of a Right
Certificate,  in accordance  with Section 25, a notice of such proposed  action,
which shall  specify the record  date for the  purposes of such stock  dividend,
distribution of rights or warrants, or the date on which such  reclassification,
consolidation,  merger, sale, transfer, liquidation,  dissolution, or winding up
is to take place and the date of  participation  therein  by the  holders of the
Preferred Shares and/or Common Shares, if any such date is to be fixed, and such
notice shall be so given in the case of any action  covered by clause (a) or (b)
above at least ten (10) days prior to the record date for determining holders of
the  Preferred  Shares for purposes of such action,  and in the case of any such
other  action,  at least ten (10) days  prior to the date of the  taking of such
proposed  action or the date of  participation  therein  by the  holders  of the
Preferred Shares and/or Common Shares, whichever shall be the earlier.

                  In case any event set forth in Section 11.1.2 or Section 13
shall  occur,  then,  in any  such  case,  (i)  the  Company  shall  as  soon as
practicable  thereafter  give to the Rights  Agent and to each holder of a Right
Certificate,  in accordance  with Section 25, a notice of the occurrence of such
event,  which notice shall describe the event and the  consequences of the event
to  holders  of  Rights  under  Section  11.1.2  and  Section  13,  and (ii) all
references in this Section 24 to Preferred Shares shall be deemed  thereafter to
refer to Common Shares and/or, if appropriate, other securities.

                  Notwithstanding anything in this Agreement to the contrary,
prior to the  Distribution  Date a filing by the Company with the Securities and
Exchange  Commission  shall  constitute  sufficient  notice  to the  holders  of
securities of the Company,  including the Rights, for purposes of this Agreement
and no other notice need be given.

     Section 25. Notices.  Notices or demands authorized by this Agreement to be
given or made by the Rights Agent or by the holder of any Right  Certificate  to
or on the Company  shall be  sufficiently  given or made if sent by  first-class
mail, postage prepaid, addressed (until another address is filed in writing with
the Rights Agent) as follows:

                  Subject to the provisions of Section 21 and Section 24, any
notice or demand authorized by this Agreement to be given or made by the Company
or by the holder of any Right  Certificate  to or on the Rights  Agent  shall be
sufficiently  given  or  made  if sent by  first-class  mail,  postage  prepaid,
addressed  (until  another  address is filed in  writing  with the  Company)  as
follows:

                                    235 Montgomery Street, 23rd Floor

                                    Attention:  William Dougherty

                  Notices or demands authorized by this Agreement to be given or
made by the Company or the Rights  Agent to the holder of any Right  Certificate
(or,  prior  to  the  Distribution  Date,  to  the  holder  of  any  certificate
representing  Common  Shares)  shall  be  sufficiently  given or made if sent by
first-class  mail,  postage prepaid,  addressed to such holder at the address of
such holder as shown on the registry books of the Company.

                  Any notices or demands given or made under this section shall
be deemed  given or made five (5) Business  Days after having been  deposited in
the mail with  postage  prepaid.  If a notice or demand is mailed in the  manner
provided above within the time prescribed,  it is duly given, whether or not the
addressee receives it.

     Section  26.  Supplements  and  Amendments.  For so long as the  Rights are
redeemable,  the Company may in its sole and absolute discretion, and the Rights
Agent shall,  if the Company so directs,  supplement  or amend any  provision of
this  Agreement in any respect  without the approval of any holders of Rights or
Common Shares. From and after the time that the Rights are no longer redeemable,
the Company may, and the Rights  Agent  shall,  if the Company so directs,  from
time to time  supplement  or amend this  Agreement  without the  approval of any
holders of Rights (i) to cure any  ambiguity  or to  correct or  supplement  any
provision contained herein which may be defective or inconsistent with any other
provisions  herein, or (ii) to make any other changes or provisions in regard to
matters or questions  arising  hereunder which the Company may deem necessary or
desirable,  including  but not limited to extending the Final  Expiration  Date;
provided,  however,  that no such supplement or amendment shall adversely affect
the  interests of the holders of Rights as such (other than an Acquiring  Person
or an Affiliate or Associate of an Acquiring Person),  and no such supplement or
amendment  may  cause  the  Rights  again to  become  redeemable  or cause  this
Agreement again to become amendable other than in accordance with this sentence;
provided  further,  that the  right of the  Board of  Directors  to  extend  the
Distribution Date shall not require any amendment or supplement hereunder.  Upon
the delivery of a certificate  from an appropriate  officer of the Company which
states that the proposed supplement or amendment is in compliance with the terms
of this Section 26 and provided such  supplement or amendment does not change or
increase the Rights Agent's duties,  liabilities or obligations  hereunder,  the
Rights Agent shall execute such  supplement or amendment.  Without  limiting the
foregoing,  at any time  prior to such time as any Person  becomes an  Acquiring
Person,  the Company and the Rights Agent may amend this  Agreement to lower the
thresholds set forth in Sections 1.1 and 3.1 to not less than the greater of (i)
any percentage  greater than the largest  percentage of the  outstanding  Common
Shares then known by the Company to be  beneficially  owned by any Person (other
than an Exempt Person) and (ii) 10%.

                                       37


     Section 27.       Exchange.

                27.1 Exchange of Common Shares for Rights. The Company may, at
its option, at any time after the occurrence of a Trigger Event, exchange Common
Shares for 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  11.1.2) at an exchange  ratio of that number of Common Shares having an
aggregate  value equal to the Spread (with such value being based on the Current
Per Share Market Price (as  determined  pursuant to Section 11.4) on the date of
the occurrence of a Trigger Event) per Right,  appropriately adjusted to reflect
any stock split, stock dividend or similar transaction  occurring after the date
hereof (such  amount per Right being  hereinafter  referred to as the  "Exchange
Consideration").  Notwithstanding  the  foregoing,  the  Company  shall  not  be
empowered to effect such exchange at any time after any  Acquiring  Person shall
have  become  the  Beneficial  Owner of 50% or more of the  Common  Shares  then
outstanding.  From and after the  occurrence  of an event  specified  in Section
13.1,  any Rights  that  theretofore  have not been  exchanged  pursuant to this
Section 27.1 shall  thereafter be exercisable only in accordance with Section 13
and may not be  exchanged  pursuant to this  Section  27.1.  The exchange of the
Rights by the Company may be made effective at such time, on such basis and with
such conditions as the Board of Directors in its sole discretion may establish.

                27.2 Exchange Procedures. Immediately upon the action of the
Board of Directors ordering the exchange for any Rights pursuant to Section 27.1
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  the  Exchange  Consideration.  The  Company  shall
promptly give public notice of any such exchange;  provided,  however,  that the
failure to give,  or any defect in, such notice shall not affect the validity of
such exchange.  The Company promptly shall mail a notice of any such exchange to
all of the  holders of such Rights at their last  addresses  as they appear upon
the registry books of the Rights Agent. Any notice which is mailed in the manner
herein  provided shall be deemed given,  whether or not the holder  receives the
notice.  Each  such  notice of  exchange  shall  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
the Rights that have become null and void pursuant to the  provisions of Section
11.1.2) held by each holder of Rights.

                27.3 Insufficient Shares. The Company may at its option
substitute,  and, in the event that there shall not be sufficient  Common Shares
issued but not  outstanding  or authorized but unissued to permit an exchange of
Rights for Common Shares as contemplated in accordance with this Section 27, the
Company shall  substitute to the extent of such  insufficiency,  for each Common
Share that would  otherwise be issuable  upon  exchange of a Right,  a number of
Preferred  Shares or fraction  thereof (or Equivalent  Preferred  Stock, as such
term is defined in Section  11.2) such that the Current Per Share  Market  Price
(determined  pursuant to Section  11.4) of one  Preferred  Share (or  equivalent
preferred  share)  multiplied by such number or fraction is equal to the Current
Per Share Market Price of one Common Share (determined pursuant to Section 11.4)
as of the date of such exchange.

                                       38

the Rights  Agent and the  registered  holders of the Right  Certificates  (and,
prior to 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

sentence of Rule  13d-3(d)(1)(i)  of the General Rules and Regulations under the
Exchange  Act.  The  Board of  Directors  shall  have the  exclusive  power  and
authority to  administer  this  Agreement  and to exercise the rights and powers

clause (y) below,  all omissions with respect to the foregoing) that are done or
made by the Board of Directors in good faith shall (x) be final,  conclusive and
binding on the Company,  the Rights Agent,  the holders of the Rights,  as such,
and all  other  parties,  and (y) not  subject  the  Board of  Directors  to any
liability to the holders of the Rights.

Exhibit A



                          BIOMARIN PHARMACEUTICAL INC.

                                     Form of
               Certificate Of Designation, Preferences And Rights

                                       of

                  Series B Junior Participating Preferred Stock

                                       of

                          BioMarin Pharmaceutical Inc.

                         -----------------------------

     The   undersigned   officer   of   BioMarin    Pharmaceutical   Inc.   (the
"Corporation"),  a corporation organized and existing under the Delaware General
Corporation  Law  (the  "DGCL"),  does  hereby  certify  that,  pursuant  to the
authority  conferred upon the Board of Directors of the Corporation  (the "Board
of  Directors")  by  Article  IV of  the  Certificate  of  Incorporation  of the
Corporation  (the  "Certificate  of  Incorporation"),  the Board of Directors on
September 11, 2002 adopted the following resolution creating a series of 750,000
shares of preferred stock designated as Series B Junior Participating  Preferred
Stock:

     RESOLVED,  that pursuant to the authority  vested in the Board of Directors
by Article IV of the Restated Certificate of Incorporation of the Corporation, a
series of preferred stock of the Corporation be, and it hereby is, created,  and
that the designation  and amount thereof and the voting powers,  preferences and
relative, participating, optional and other special rights of the shares of such
series,  and the  qualifications,  limitations  or  restrictions  thereof are as
follows:

                  SERIES B JUNIOR PARTICIPATING PREFERRED STOCK

     Section 1.  Designation  and  Amount.  The shares of such  series  shall be
designated as Series B Junior Participating Preferred Stock, $.001 par value per
share (the "Series B Preferred  Stock"),  and the number of shares  constituting
the Series B Preferred Stock shall be  seven-hundred  fifty thousand  (750,000).
Such number of shares may be increased or decreased by  resolution  of the Board
of Directors;  provided,  that no decrease  shall reduce the number of shares of
Series B  Preferred  Stock to a number  less  than the  number  of  shares  then
outstanding plus the number of shares reserved for issuance upon the exercise of
outstanding  options,   rights  or  warrants  or  upon  the  conversion  of  any
outstanding  securities  issued by the  Corporation  convertible  into  Series B
Preferred Stock.

                                      A-1


Section 2.        Dividends and Distributions.

        (A) Subject to the prior and superior rights of the holders of any
shares of any class or series  of stock of this  Corporation  ranking  prior and
superior to the Series B Preferred Stock with respect to dividends,  the holders
of shares of Series B Preferred  Stock,  in  preference to the holders of Common
Stock, par value $.001 per share (the "Common Stock"),  of the Corporation,  and
of any other  stock  ranking  junior to the Series B Preferred  Stock,  shall be
entitled to receive, when, as and if authorized by the Board of Directors out of
funds legally available for the purpose,  quarterly dividends payable in cash on
the  fifteenth day of January,  April,  July and October of 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 B Preferred  Stock, in an amount per
share  (rounded to the nearest cent) equal to the greater of (a) $0.01 or (b) an
amount,  subject to the provision for adjustment hereinafter set forth, equal to
100 times the  aggregate per share amount of all cash  dividends,  and 100 times
the  aggregate per share amount  (payable in kind) of all non-cash  dividends or
other distributions,  other than a dividend payable in shares of Common Stock or
a subdivision of the outstanding shares of Common Stock (by  reclassification or
otherwise),  declared  on the  Common  Stock  since  the  immediately  preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment  Date,  since the first  issuance of any share or fraction of a share of
Series B Preferred Stock. In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock  payable in shares of Common  Stock,  or
effect a subdivision,  combination or consolidation of the outstanding shares of
Common Stock (by  reclassification or otherwise than by payment of a dividend in
shares of Common  Stock)  into a  greater  or lesser  number of shares of Common
Stock,  then in each such case the amount to which holders of shares of Series B
Preferred Stock were entitled  immediately  prior to such event under clause (b)
of the  preceding  sentence  shall be adjusted by  multiplying  such amount by a
fraction,  the  numerator  of which is the  number of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

        (B) The Corporation shall declare a dividend or distribution on the
Series  B  Preferred  Stock as  provided  in  paragraph  (A) of this  Section  2
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 $0.01 per share on the
Series B  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 B Preferred Stock from the Quarterly Dividend Payment Date next
preceding  the date of issue of such  shares,  unless  the date of issue of such
shares is prior to the  record  date for the first  Quarterly  Dividend  Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such  shares,  or unless the date of issue is a  Quarterly  Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of
                                      A-2


Series B 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 B 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 B Preferred  Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

        (D) In determining whether a distribution (other than upon voluntary or
involuntary liquidation), by dividend, redemption or other acquisition of shares
of stock of the Corporation or otherwise,  is permitted under the DGCL,  amounts
that would be needed, if the Corporation were to be dissolved at the time of the
distribution,  to satisfy the preferential rights upon dissolution of holders of
the  Series B  Preferred  Stock  shall not be added to the  Corporation's  total
liabilities.

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

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

        (B) Except as otherwise provided herein, in the Certificate of
Incorporation,  or in any other  Certificate  of  Designation,  Preferences  and
Rights creating a series of Preferred Stock or any similar stock, the holders of
shares of Series B Preferred Stock and the holders of shares of Common Stock and
any other shares of stock of the Corporation  having general voting rights shall
vote together as one class on all matters submitted to a vote of stockholders of
the Corporation.

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

                                      A-3


        Section 4.        Certain Restrictions.

        (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series B 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 B 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 B 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 B
                           Preferred Stock, except dividends paid ratably on the
                           Series B 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 shares of any stock ranking junior
                           (either as to dividends or upon liquidation,
                           dissolution or winding up) to the Series B 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 (both as to
                           dividends and upon dissolution, liquidation or
                           winding up) to the Series B Preferred Stock; or

                (iv)       redeem or purchase or otherwise acquire for
                           consideration any shares of Series B Preferred Stock,
                           or any shares of stock ranking on a parity with the
                           Series B 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 B  Preferred  Stock
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall  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  Certificate  of
Incorporation,  or in any other  Certificate  of  Designation,  Preferences  and
Rights creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

                                      A-4


     Section 6. Liquidation, Dissolution or Winding Up.

        (A) Upon any liquidation, dissolution or winding up of the Corporation,
voluntary  or  otherwise  no  distribution  shall be made (1) to the  holders of
shares of stock  ranking  junior  (either as to dividends  or upon  liquidation,
dissolution  or  winding  up) to the  Series B  Preferred  Stock  unless,  prior
thereto,  the holders of shares of Series B Preferred  Stock shall have received
an amount per share (the "Series B Liquidation Preference") equal to $10,000 per
share,  plus an amount equal to accrued and unpaid  dividends and  distributions
thereon, whether or not declared, to the date of such payment, provided that the
holders of shares of Series B  Preferred  Stock  shall be entitled to receive an
aggregate amount per share, subject to the provision for adjustment  hereinafter
set forth,  equal to 100 times the aggregate  amount to be distributed per share
to holders of shares of Common  Stock,  or (2) to the holders of shares of stock
ranking on a parity (either as to dividends or upon liquidation,  dissolution or
winding up) with the Series B Preferred Stock, except distributions made ratably
on the Series B Preferred  Stock and all such parity stock in  proportion to the
total  amounts to which the  holders of all such shares are  entitled  upon such
liquidation,  dissolution or winding up. In the event the  Corporation  shall at
any time declare or pay any  dividend on the Common  Stock  payable in shares of
Common Stock,  or effect a  subdivision,  combination  or  consolidation  of the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock,  then in each such case the aggregate amount to which
holders of shares of Series B Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the  preceding  sentence  shall be
adjusted by multiplying  such amount by a fraction the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of  Common  Stock  that are
outstanding immediately prior to such event.

        (B) In the event, however, that there are not sufficient assets
available to permit  payment in full of the Series B Liquidation  Preference and
the  liquidation  preferences  of all other  classes  and series of stock of the
Corporation,  if any, that rank on a parity with the Series B Preferred Stock in
respect  thereof,  then the  assets  available  for such  distribution  shall be
distributed  ratably  to the  holders of the  Series B  Preferred  Stock and the
holders of such parity  shares in  proportion  to their  respective  liquidation
preferences.

        (C) Neither the merger or consolidation of the Corporation into or with
another  corporation nor the merger or  consolidation  of any other  corporation
into or with the Corporation shall be deemed to be a liquidation, dissolution or
winding up of the Corporation within the meaning of this Section 6.

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,

                                      A-5


cash  and/or  any other  property,  then in any such case each share of Series B
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 100 times the aggregate  amount of stock,  securities,  cash and/or any
other  property  (payable in kind),  as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time  declare or pay any  dividend on the Common  Stock  payable in
shares of Common Stock, or effect a subdivision, combination or consolidation of
the outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common  Stock,  then in each such case the  amount set forth in the
preceding  sentence with respect to the exchange or change of shares of Series B
Preferred Stock shall be adjusted by multiplying such amount by a fraction,  the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

     Section 8. No Redemption.  The shares of Series B Preferred Stock shall not
be redeemable by the Company.

     Section 9. Rank. The Series B Preferred  Stock shall rank,  with respect to
the  payment of  dividends  and the  distribution  of assets  upon  liquidation,
dissolution  or winding up,  junior to the Series A  Non-Voting  Non-Convertible
Preferred  Stock and all other  series of any other  class of the  Corporation's
Preferred  Stock,  except to the extent that any such other series  specifically
provides that it shall rank on a parity with or junior to the Series B Preferred
Stock.

     Section 10.  Amendment.  At any time any shares of Series B Preferred Stock
are outstanding,  neither the Certificate of Incorporation  nor this Certificate
of  Designation,  Preferences  and Rights  shall be amended in any manner  which
would  materially  alter or change the powers,  preferences or special rights of
the  Series B  Preferred  Stock,  as set  forth  herein,  so as to  affect  them
adversely  without the affirmative vote of the holders of at least two-thirds of
the  outstanding  shares of Series B Preferred  Stock,  voting  separately  as a
single class.

     Section 11.  Fractional  Shares.  Series B Preferred Stock may be issued in
fractions  of a share that shall  entitle  the  holder,  in  proportion  to such
holder's  fractional  shares,  to exercise  voting  rights,  receive  dividends,
participate  in  distributions  and to have the  benefit of all other  rights of
holders of Series B Preferred Stock.

     Second.  The shares of Series B Preferred  Stock have been  classified  and
designated  by the Board of  Directors  under  the  authority  contained  in the
Certificate of Incorporation.

     Third.  This  Certificate of  Designation,  Preferences and Rights has been
approved  by the Board of  Directors  in the manner and by the vote  required by

                           BIOMARIN PHARMACEUTICAL INC.

     This  certifies  that  __________________,  or registered  assigns,  is the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the Rights
Agreement,  dated as of September  11, 2002 as the same may be amended from time
to time (the  "Agreement"),  between  BioMarin  Pharmaceutical  Inc., a Delaware
corporation  (the  "Company"),  and Mellon  Investor  Services LLC, a New Jersey
limited  liability  company,  as Rights Agent (the "Rights Agent"),  to purchase
from the Company at any time after the Distribution  Date and prior to 5:00 p.m.
(Pacific time) on September 23, 2012, at the offices of the Rights Agent, or its
successors as Rights Agent,  designated for such purpose, one one-hundredth of a
fully  paid,  nonassessable  share of  Series B Junior  Participating  Preferred
Stock, $.001 par value per share (the "Preferred  Shares") of the Company,  at a
purchase  price of $35.00 per  one-hundredth  of a Preferred  Share,  subject to
adjustment (the "Purchase Price"), upon presentation and surrender of this Right
Certificate  with  the Form of  Election  to  Purchase  and  certification  duly
executed.  The number of Rights  represented by this Right  Certificate (and the
number of  one-hundredths  of a  Preferred  Share  which may be  purchased  upon
exercise  thereof) set forth above,  and the Purchase Price set forth above, are
the number and Purchase  Price as of September  11, 2002 based on the  Preferred
Shares  as  constituted  at such  date.  Capitalized  terms  used in this  Right
Certificate  without  definition shall have the meanings ascribed to them in the
Agreement.  As provided in the  Agreement,  the Purchase Price and the number of
Preferred  Shares  which  may be  purchased  upon  the  exercise  of the  Rights
represented by this Right Certificate are subject to modification and adjustment
upon the happening of certain events.  The Company reserves the right to require
prior to the  occurrence  of a Trigger  Event (as such  term is  defined  in the
Agreement) that, upon any exercise of Rights, a number of Rights be exercised so
that only whole shares of Preferred Stock will be issued.

                                      B-1


     This Right  Certificate  is subject  to all of the  terms,  provisions  and
conditions of the Agreement,  which terms,  provisions and conditions are hereby
incorporated  herein by reference and made a part hereof and to which  Agreement
reference is hereby made for a full  description  of the rights,  limitations of
rights,  obligations,  duties and immunities  hereunder of the Rights Agent, the
Company and the holders of the Right  Certificates.  Copies of the Agreement are
on file at the  principal  offices of the  Company  and the office of the Rights
Agent designated to the Company for such purposes.

     This Right  Certificate,  with or without  other Right  Certificates,  upon
surrender at the offices of the Rights Agent designated for such purpose, may be
exchanged for another Right Certificate or Right  Certificates of like tenor and
date  representing  Rights  entitling the holder to purchase the same  aggregate
number of one-hundredths  of a Preferred Share as the Rights  represented 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 Agreement,  the Board of Directors may, at
its option,  (i) redeem the Rights  represented  by this Right  Certificate at a
redemption  price of $.001  per Right or (ii)  exchange  Common  Shares  for the
Rights  represented by this Certificate,  in whole or in part.  Immediately upon
the action of the Board of  Directors  authorizing  redemption,  the Rights will
terminate  and the only right of the  holders of Rights  will be to receive  the
redemption price.

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

     No holder of this Right Certificate,  as such, shall be entitled to vote or
receive  dividends  or be deemed for any  purpose  the  holder of the  Preferred
Shares  or of any  other  securities  of the  Company  which  may at any time be
issuable on the exercise hereof,  nor shall anything  contained in the Agreement
or herein be construed  to confer upon the holder  hereof,  as such,  any of the
rights of a stockholder  of the Company or any right to vote for the election of
directors or upon any matter  submitted to stockholders at any meeting  thereof,
or to give or withhold consent to any corporate  action, or to receive notice of
meetings  or other  actions  affecting  stockholders  (except as provided in the
Agreement) or to receive dividends or subscription  rights, or otherwise,  until
the  Right or Rights  represented  by this  Right  Certificate  shall  have been
exercised as provided in the Agreement.

     If any term, provision, covenant or restriction of the 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 the Agreement shall remain in full force and effect and shall in
no way be affected, impaired or invalidated.

                                      B-2


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

Exhibit C


As described in the Rights Agreement, as defined below, Rights which are held by
or have been held by an Acquiring Person or Associates or Affiliates thereof (as
defined in the Rights  Agreement) and certain  transferees  thereof are null and
void and are not transferable.

                 SUMMARY OF RIGHTS TO PURCHASE PREFERRED SHARES

On September  11, 2002 the Board of Directors  of BioMarin  Pharmaceutical  Inc.
(the  "Company")  authorized a dividend of one preferred share purchase right (a
"Right")  for each  share of common  stock,  $.001 par value per share  ("Common
Shares") of the Company  outstanding  at the close of business on September  23,
2002 (the  "Record  Date").  As long as the  Rights are  attached  to the Common
Shares,  the Company will issue one Right (subject to adjustment)  with each new
Common  Share  so  that  all  such  shares  will  have  attached  Rights.   When
exercisable,  each Right will entitle the registered holder to purchase from the
Company one one-hundredth of a share of Series B Junior Participating  Preferred
Stock  (the  "Preferred  Shares")  at a price of $35.00 per  one-hundredth  of a
Preferred Share,  subject to adjustment (the "Purchase Price").  The description
and  terms  of the  Rights  are set  forth in a  Rights  Agreement,  dated as of
September  11,  2002,  as the same may be amended from time to time (the "Rights
Agreement"),  between the Company and Mellon Investor Services LLC, a New Jersey
limited liability company, as Rights Agent (the "Rights Agent").

Initially,  the  Rights  will  be  attached  to all  Common  Stock  certificates
evidencing shares then outstanding,  and no separate Rights certificates will be
distributed.  Until the earlier to occur of (i) ten (10) days following a public
announcement  that a person or group of  affiliated  or  associated  persons has
acquired, or obtained the right to acquire,  beneficial ownership of 15% or more
of the Common Shares (an "Acquiring  Person") or (ii) ten (10) business days (or
such later date as may be determined  by action of the Board of Directors  prior
to such time as any person or group of affiliated  persons  becomes an Acquiring
Person)  following the  commencement  or  announcement of an intention to make a
tender  offer or exchange  offer the  consummation  of which would result in the
beneficial  ownership  by a person or group of 15% or more of the Common  Shares
(the earlier of (i) and (ii) being called the "Distribution  Date"),  the Rights
will be  represented,  with  respect  to any of the  Common  Share  certificates
outstanding as of the Record Date, by such Common Share certificate.

The Rights  Agreement  provides  that until the  Distribution  Date (or  earlier
redemption,  exchange, termination or expiration of the Rights), the Rights will
be transferred with and only with the Common Shares. Until the Distribution Date
(or earlier redemption,  exchange, termination or expiration of the Rights), new
Common Share certificates  issued after the close of business on the Record Date
upon  transfer  or new  issuance of the Common  Shares  will  contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier  redemption,  exchange,  termination  or expiration of the Rights),  the
surrender for transfer of any  certificates  for Common Shares,  with or without
such  notation or a copy of this  Summary of Rights,  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  representing the Rights ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution Date and such separate Right  Certificates alone will represent the
Rights.

                                      C-1


The Rights are not  exercisable  until the  Distribution  Date.  The Rights will
expire on September 23, 2012 subject to the Company's  right to extend such date
(the "Final  Expiration  Date"),  unless  earlier  redeemed or  exchanged by the
Company or terminated.

Each Preferred Share  purchasable  upon exercise of the Rights will be entitled,
when, as and if declared,  to a minimum preferential  quarterly dividend payment
of $0.01 per share but will be  entitled to an  aggregate  dividend of 100 times
the dividend,  if any,  declared per Common Share.  In the event of liquidation,
dissolution  or winding up of the Company,  the holders of the Preferred  Shares
will be entitled to a minimum  preferential  liquidation  payment of $10,000 per
share  (plus any  accrued  but  unpaid  dividends)  but will be  entitled  to an
aggregate payment of 100 times the payment made per Common Share. Each Preferred
Share  will  have 100  votes  and will vote  together  with the  Common  Shares.
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged,  each  Preferred  Share will be entitled to receive
100 times the amount  received per Common  Share.  Preferred  Shares will not be
redeemable.  These rights are  protected by customary  antidilution  provisions.
Because of the nature of the Preferred Share's dividend,  liquidation and voting
rights,  the value of one  one-hundredth  of a Preferred Share  purchasable upon
exercise of each Right should approximate the value of one Common Share.

The  Purchase  Price  payable,  and the  number  of  Preferred  Shares  or other
securities  or  property  issuable,  upon  exercise of the Rights are subject to
adjustment  from time to time to  prevent  dilution  (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares or  convertible
securities  at less than the current  market  price of the  Preferred  Shares or
(iii) upon the  distribution to holders of the Preferred  Shares of evidences of
indebtedness,  cash,  securities or assets or of subscription rights or warrants
(other than those referred to above).

In the event that a person becomes an Acquiring  Person or if the Company is the
surviving  corporation in a merger with an Acquiring  Person or any affiliate or
associate  of an  Acquiring  Person and the Common  Shares  were not  changed or
exchanged,  each holder of a Right,  other than Rights that are or were acquired
or beneficially  owned by the Acquiring Person (which Rights will be void), will
thereafter  have the right to receive,  upon  exercise  thereof,  that number of
Common Shares having a market value of two times the then-current Purchase Price
of the Right. In the event that, after a person has become an Acquiring  Person,
the Company is acquired in a merger or other business combination transaction or
more than 50% of its assets or earning power are sold, proper provision shall be
made so that each holder of a Right shall  thereafter have the right to receive,
upon the exercise thereof at the then-current  Purchase Price of the Right, that
number of shares of common stock of the  acquiring  company which at the time of
such  transaction  would  have a market  value  of two  times  the  then-current
Purchase Price of the Right.

                                      C-2


For example,  at an exercise price of $35.00 per Right,  each Right not owned by
an Acquiring  Person (or by certain related  parties)  following a Trigger Event
would  entitle its holder to  purchase  $70.00  worth of Common  Stock (or other
consideration,  as noted above) for $35.00. Assuming that the Common Stock had a
per share value of $10.00 at such time,  the holder of each valid Right would be
entitled to purchase seven shares of Common Stock for $35.00.

At any time after a person becomes an Acquiring  Person and prior to the earlier
of one of the events described in the last sentence of the previous paragraph or
the  acquisition  by such  Acquiring  Person  of 50% or more of the  outstanding
Common  Shares,  the Board of  Directors  may cause the Company to exchange  the
Rights (other than Rights owned by an Acquiring Person,  which will be void), in
whole or in part,  for that number of Common  Shares  having an aggregate  value
equal to the Spread (the excess of the value of the Common Shares  issuable upon
the  exercise  of a Right  over  the  Purchase  Price)  per  Right  (subject  to
adjustment).

No  adjustment  in  the  Purchase  Price  will  be  required  until   cumulative
adjustments  require an  adjustment  of at least 1% in the  Purchase  Price.  No
fractional  Preferred  Shares  or  Common  Shares  will be  issued  (other  than
fractions of Preferred Shares which are integral  multiples of one one-hundredth
of a Preferred Share, which may, at the election of the Company,  be represented
by depository  receipts),  and in lieu  thereof,  a payment in cash will be made
based on the market price of the  Preferred  Shares or Common Shares on the last
trading date prior to the date of exercise.

The Rights may be  redeemed in whole,  but not in part,  at a price of $.001 per
Right (the  "Redemption  Price") by the Board of  Directors at any time prior to
the time that an Acquiring  Person has become such. The redemption of the Rights
may be made  effective at such time,  on such basis and with such  conditions as
the Board of Directors in its sole  discretion may establish.  Immediately  upon
any  redemption of the Rights,  the right to exercise the Rights will  terminate
and the only right of the holders of Rights  will be to receive  the  Redemption
Price.

Until a Right is  exercised,  it will not  entitle its holder to any rights as a
stockholder of the Company, including,  without limitation, the right to vote or
to receive dividends.

Any of the  provisions  of the Rights  Agreement  may be amended by the Board of
Directors  for so long as the Rights are then  redeemable,  and after the Rights
are no longer  redeemable,  the  Company  may  amend or  supplement  the  Rights
Agreement  in any manner that does not  adversely  affect the  interests  of the
holders of the Rights.

The Rights are designed to assure that all of the Company's stockholders receive
fair and equal  treatment in the event of any  proposed  takeover of the Company
and to guard against partial tender offers, open market  accumulations and other
abusive tactics to gain control of the Company without paying all stockholders a
control premium. The Rights will cause substantial dilution to a person or group
that  acquires 15% or more of the  Company's  stock on terms not approved by the
Company's Board of Directors. The Rights should not interfere with any merger or
other business combination approved by the Board of Directors at any time before
a person or group has become an Acquiring Person.

                                      C-3


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