Item 5. Other Events.

     On May 4, 1999 the Board of Directors of Silicon Storage  Technology,  Inc.
(the  "Company")  approved  the  adoption of a Share  Purchase  Rights Plan (the
"Plan").  Terms of the Plan provide for a dividend distribution of one preferred
share purchase right (a "Right") for each outstanding  share of common stock, no
par value (the "Common Shares"),  of the Company. The dividend is payable on May
27, 1999 (the "Record Date") to the  shareholders  of record on that date.  Each
Right  entitles  the  registered   holder  to  purchase  from  the  Company  one
one-hundredth  of a share of Series A Junior  Participating  Preferred Stock, no
par value (the "Preferred  Shares"),  at a price of $40.00 per one one-hundredth
of a Preferred  Share (the "Purchase  Price"),  subject to adjustment.  Each one
one-hundredth  of a share of  Preferred  Shares  has  designations  and  powers,
preferences and rights,  and the  qualifications,  limitations and  restrictions
which make its value  approximately  equal to the value of a Common  Share.  The
description  and terms of the  Rights are set forth in a Rights  Agreement  (the
"Rights  Agreement"),  dated as of May 4, 1999  entered into between the Company
and  American  Stock  Transfer & Trust  Company,  as rights  agent (the  "Rights
Agent").

     Initially,   the  Rights  will  be  evidenced  by  the  stock  certificates
representing  the  Common  Shares  then  outstanding,   and  no  separate  Right
Certificates, as defined, will be distributed. Until the earlier to occur of (i)
the date of a public  announcement that a person,  entity or group of affiliated
or associated persons have acquired  beneficial  ownership of 15% or more of the
outstanding  Common Shares (an "Acquiring  Person") or (ii) 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 entity becomes an Acquiring  Person) following the
commencement of, or announcement of an intention to commence,  a tender offer or
exchange  offer the  consummation  of which would result in any person or entity
becoming  an  Acquiring  Person  (the  earlier  of such dates  being  called the
"Distribution  Date"), the Rights will be evidenced,  with respect to any of the
Common Share  certificates  outstanding  as of the Record  Date,  by such Common
Share  certificate  with or without a copy of the  Summary  of Rights,  which is
included in the Rights Agreement as Exhibit C thereof (the "Summary of Rights").

     Until the Distribution  Date, the Rights will be transferable with and only
with the Common Shares.  Until the Distribution  Date (or earlier  redemption or
expiration of the Rights), new Common Share certificates issued after the Record
Date,  upon transfer or new issuance of Common  Shares,  will contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier  redemption or  expiration of the Rights),  the surrender or transfer of
any  certificates  for Common  Shares  outstanding  as of the Record Date,  even
without such notation or a copy of the Summary of Rights being attached thereto,
will also  constitute  the  transfer  of the Rights  associated  with the Common
Shares  represented by such  certificate.  As soon as practicable  following the
Distribution  Date,   separate   certificates   evidencing  the  Rights  ("Right
Certificates")  will be mailed to holders  of record of the Common  Shares as of
the  close  of  business  on the  Distribution  Date  and  such  separate  Right
Certificates alone will evidence the Rights.



                                       2.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on May 3, 2009 (the  "Final  Expiration  Date"),  unless  the  Rights are
earlier redeemed or exchanged by the Company, in each case, as described below.

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

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

     Preferred  Shares  purchasable  upon  exercise  of the  Rights  will not be
redeemable.  Each  Preferred  Share will be entitled  to a minimum  preferential
quarterly  dividend  payment  of $1.00  but  will be  entitled  to an  aggregate
dividend of 100 times the dividend  declared per Common  Share.  In the event of
liquidation,  the holders of the Preferred Shares would be entitled to a minimum
preferential  liquidation  payment of $100 per share,  but would be  entitled to
receive an  aggregate  payment  equal to 100 times the  payment  made per Common
Share. Each Preferred Share will have 100 votes, voting together with the Common
Shares. Finally, in the event of any merger,  consolidation or other transaction
in which Common Shares are exchanged,  each Preferred  Share will be entitled to
receive 100 times the amount of consideration  received per Common Share.  These
rights are  protected  by  customary  anti-dilution  provisions.  Because of the
nature of the Preferred  Shares' dividend and liquidation  rights,  the value of
one  one-hundredth  of a Preferred  Share  should  approximate  the value of one
Common Share.  The Preferred Shares would rank junior to any other series of the
Company's preferred stock.

     In the event that any person or group of affiliated  or associated  persons
becomes an Acquiring Person,  proper provision shall be made so that each holder
of a Right, other than Rights beneficially owned by the Acquiring Person and its
associates and  affiliates  (which will  thereafter be void),  will for a 60-day
period have the right to receive  upon  exercise  that  number of Common  Shares
having a market value of two times the exercise  price of the Right (or, if such
number  of  shares  is not and  cannot  be  authorized,  the  Company  may issue
Preferred Shares, cash, debt, stock or a combination thereof in exchange for the
Rights).  This right will  terminate  60 days after the date on which the Rights
become  nonredeemable  (as  described  below),  unless there



                                       3.
<PAGE>


is an injunction or similar  obstacle to exercise of the Rights,  in which event
this right  will  terminate  60 days  after the date on which the  Rights  again
become exercisable.

     Generally,  under the Plan,  an  "Acquiring  Person" shall not be deemed to
include (i) the Company,  (ii) a subsidiary  of the Company,  (iii) any employee
benefit or  compensation  plan of the Company,  (iv) any entity  holding  Common
Shares for or pursuant to the terms of any such employee benefit or compensation
plan or (v) an  Excluded  Person  (as  such  term is  hereinafter  defined).  In
addition,  except under limited circumstances,  no person or entity shall become
an Acquiring  Person as the result of the  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 or entity to
15% or more of the Common Shares then  outstanding.  Bing Yeh, together with his
associates and affiliates, will be an Excluded Person.

     In the event that the  Company is  acquired  in a merger or other  business
combination  transaction  or 50% or more of its  consolidated  assets or earning
power are sold to an Acquiring  Person,  its associates or affiliates or certain
other persons in which such persons have an interest,  proper  provision will be
made so that each holder of a Right will  thereafter  have the right to receive,
upon the exercise thereof at the then current exercise price of the Right,  that
number of shares of common stock of the  acquiring  company which at the time of
such transaction will have a market value of two times the exercise price of the
Right.

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

     With  certain  exceptions,  no  adjustment  in the  Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase Price. No fractional  Preferred  Shares will be issued (other than
fractions which are integral  multiples of the number of one one-hundredths of a
Preferred  Share  issuable  upon the  exercise  of one Right,  which may, at the
election of the  Company,  be  evidenced by  depositary  receipts),  and in lieu
thereof,  an  adjustment  in cash will be made based on the market  price of the
Preferred Shares on the last trading day prior to the date of exercise.

     At any  time  prior  to the  earliest  of (i) the day of the  first  public
announcement  that a person  has  become an  Acquiring  Person or (ii) the Final
Expiration  Date, the Board of Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (the  "Redemption  Price").
Following the expiration of the above periods, the Rights become  nonredeemable.
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.



                                       4.
<PAGE>


     The terms of the Rights may be  amended  by the Board of  Directors  of the
Company  without the consent of the holders of the Rights,  except that from and
after such time as the rights are  distributed  no such  amendment may adversely
affect the interest of the holders of the Rights  excluding  the interests of an
Acquiring Person.

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

     The Rights  have  certain  anti-takeover  effects.  The  Rights  will cause
substantial  dilution to a person or group that  attempts to acquire the Company
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 since the Rights may be amended to permit such acquisition or redeemed
by the  Company at $.01 per Right  prior to the  earliest of (i) the time that a
person or group has acquired  beneficial  ownership of 15% or more of the Common
Shares or (ii) the final expiration date of the rights.

                                  PRESS RELEASE

SST ADOPTS SHAREHOLDER RIGHTS PLAN

     Sunnyvale, California, May 4, 1999 - SST (SILICON STORAGE TECHNOLOGY, INC.)
(Nasdaq:  SSTI) announced that its Board of Directors approved the adoption of a
Shareholder  Rights  Plan under which all  shareholders  of record as of May 27,
1999 will receive rights to purchase shares of a new series of Preferred Stock.

     The Rights Plan is designed to enable all SST  shareholders  to realize the
full value of their  investment and to provide for fair and equal  treatment for
all  shareholders  in the event that an  unsolicited  attempt is made to acquire
SST.  The  adoption of the Rights  Plan is intended as a means to guard  against
abusive takeover tactics and is not in response to any particular proposal.

     The rights will be distributed as a non-taxable dividend and will expire in
ten years from the record date. The rights will be exercisable  only if a person
or group  acquires  15 percent or more of the SST Common  Stock or  announces  a
tender offer for 15 percent or more of the Common Stock. If a person acquires 15
percent or more of SST's Common Stock, all  rightsholders  except the buyer will
be  entitled to acquire  SST Common  Stock at a discount.  The effect will be to
discourage  acquisitions  of more than 15 percent of SST's Common Stock  without
negotiations  with the  Board.  Bing  Yeh,  the  Company's  President  and Chief
Executive Officer,  and his affiliates and associates will be exempt from the 15
percent limitation under the Rights Plan.

     The rights will trade with SST's  Common  Stock,  unless and until they are
separated upon the occurrence of certain future events. The rights  distribution
is not taxable to the  shareholders.  SST's Board of Directors may terminate the
Rights Plan at any time or redeem the rights prior to the time a person acquires
more than 15 percent of the SST Common Stock.  Additional  details regarding the
Rights  Plan  will be  outlined  in a summary  to be mailed to all  shareholders
following the record date.

     Headquartered  in  Sunnyvale,  California,  SST designs,  manufactures  and
markets  a  diversified  range  of  nonvolatile   memory  solutions,   based  on
proprietary,  patented SuperFlash technology,  for the computer,  communications
and   consumer    markets.    SST's   product   families    include    low-cost,
high-functionality  flash memory  components and CompactFlash  card mass storage
products.  SST also offers its SuperFlash  technology for embedded  applications

                                RIGHTS AGREEMENT


     THIS  RIGHTS  AGREEMENT  ("Agreement"),  dated as of May 4,  1999,  between
Silicon Storage Technology,  Inc., a California corporation (the "Company"), and
American Stock Transfer & Trust Company ("Rights Agent").

     The Board of  Directors  of the  Company  has  authorized  and  declared  a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as such term is  hereinafter  defined)  outstanding at the close of business on
May 27, 1999 (the "Record Date"),  each Right representing the right to purchase
one  one-hundredth  of a Preferred Share (as such term is hereinafter  defined),
upon the terms and subject to the conditions  herein set forth,  and has further
authorized  and  directed  the issuance of one Right with respect to each Common
Share that shall become outstanding  between the Record Date and the earliest to
occur of the  Distribution  Date, the Redemption  Date and the Final  Expiration
Date (as such terms are hereinafter defined); provided, however, that Rights may
be issued with respect to Common Shares that shall become  outstanding after the
Distribution  Date and prior to the earlier of the Redemption Date and the Final
Expiration Date in accordance with the provisions of Section 22 hereof.

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

     CERTAIN  DEFINITIONS.  For purposes of this Agreement,  the following terms
have the meanings indicated:

     (a)  "Acquiring  Person" shall mean any Person (as such term is hereinafter
defined) who or which,  together with all  Affiliates  and  Associates  (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is  hereinafter  defined)  of 15% or more of the  Common  Shares  then
outstanding.  Notwithstanding the foregoing, (A) the term Acquiring Person shall
not include (i) the Company,  (ii) any  Subsidiary  (as such term is hereinafter
defined) of the Company,  (iii) any employee benefit or compensation plan of the
Company or any Subsidiary of the Company,  (iv) any entity holding Common Shares
for or pursuant to the terms of any such employee benefit or compensation  plan,
or (v) an Excluded  Shareholder (as such term is hereinafter defined) and (B) no
Person  shall  become  an  "Acquiring  Person"  either  (x) 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  then  outstanding;
provided,  however, that if a Person shall become the Beneficial Owner of 15% or
more of the Common Shares then  outstanding by reason of share  purchases by the
Company and shall,  following  written notice from, or public  disclosure by the
Company of such share purchases by the Company,  become the Beneficial  Owner of
any additional  Common Shares without the prior consent of the Company and shall
then Beneficially Own more than 15% of the Common Shares then outstanding,  then
such Person shall be deemed to be an "Acquiring  Person," or (y) 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
paragraph  (a),  has become  such  inadvertently,  and such Person  divests,  as
promptly as practicable (as determined in good faith by



                                       1

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  paragraph (a), then such Person shall not be deemed to be an "Acquiring

     customary  agreements  with and  between  underwriters  and  selling  group
     members with respect to a bona fide public  offering of securities) for the
     purpose of acquiring, holding, voting (except to the extent contemplated by
     the proviso to Section  1(c)(ii)(B)  hereof) or disposing of any securities
     of  the  Company   provided,   however,   an  agreement,   arrangement   or

Subsidiary of the Company or any entity holding Common Shares for or pursuant to
the terms of any such  plan) to  commence,  a tender or  exchange  offer  (which
intention  to  commence  remains  in effect  for five  Business  Days after such
announcement),  the consummation of which would result in any Person becoming an
Acquiring  Person  (including  any such  date  which  is after  the date of this
Agreement  and prior to the  issuance of the  Rights,  the earlier of such dates
being herein  referred to as the  "Distribution  Date"),  (x) the Rights will be
evidenced by the certificates  for Common Shares  registered in the names of the
holders  thereof  (which   certificates   shall  also  be  deemed  to  be  Right
Certificates)  and not by separate Right  Certificates,  and (y) the Rights (and
the right to receive Right  Certificates  therefor) will be transferable only in
connection with the transfer of Common Shares.  As soon as practicable after the
Distribution  Date, the Company will prepare and execute,  the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid mail, to each
record holder of Common  Shares as of the Close of Business on the  Distribution
Date, at the address of such holder shown on the records of the Company, a Right
Certificate,   in  substantially   the  form  of  Exhibit  B  hereto  (a  "Right
Certificate"),  evidencing  one Right for each Common Share so held,  subject to
the  adjustment  provisions  of Section 11 of this Rights  Agreement.  As of the
Distribution   Date,  the  Rights  will  be  evidenced   solely  by  such  Right
Certificates.

     (b) On the Record Date, or as soon as practicable  thereafter,  the Company
will send (directly or through the Rights Agent or its transfer agent) a copy of
a Summary of Rights to Purchase  Preferred  Shares, in substantially the form of
Exhibit C hereto (the  "Summary of  Rights"),  by  first-class,  postage-prepaid
mail,  to each record holder of Common Shares as of the Close of Business on the
Record Date,  at the address of such holder shown on the records of the Company.
With respect to  certificates  for Common  Shares  outstanding  as of the Record
Date,  until  the  Distribution  Date,  the  Rights  will be  evidenced  by such
certificates  registered  in  the  names  of  the  holders  thereof.  Until  the
Distribution  Date  (or  the  earlier  of the  Redemption  Date  and  the  Final
Expiration  Date),  the  surrender  for transfer of any  certificate  for Common
Shares  outstanding on the Record Date shall also constitute the transfer of the
Rights associated with the Common Shares represented thereby.

     (c)  Certificates  for Common Shares which become  outstanding  (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this  paragraph  (c)) after the  Record  Date but prior to the  earliest  of the
Distribution  Date, the Redemption Date or the Final  Expiration Date shall have
impressed on, printed on, written on or otherwise  affixed to them the following
legend:

          This  certificate  also  evidences  and entitles the holder  hereof to
     certain rights as set forth in a Rights  Agreement  between Silicon Storage
     Technology,  Inc.  (the  "Company")  and  American  Stock  Transfer & Trust
     Company as Rights Agent (the "Rights  Agent"),  dated as of May 4, 1999, as
     amended from time to time (the "Rights Agreement"),  the terms of which are
     hereby  incorporated  herein by reference and a copy of which is on file at
     the   principal   executive   offices  of  the   Company.   Under   certain
     circumstances,  as set forth in the Rights  Agreement,  such Rights will be
     evidenced by separate  certificates and will no longer be evidenced by this
     certificate. The Company will mail to the holder of this


                                       5
<PAGE>


     certificate a copy of the Rights Agreement  without charge after receipt of
     a written request therefor.  As described in the Rights  Agreement,  Rights
     issued to any Person who becomes an  Acquiring  Person or an  Affiliate  or
     Associate  thereof (as defined in the Rights Agreement) and certain related
     persons,  whether  currently  held by or on behalf of such Person or by any
     subsequent holder, shall become null and void.

     With respect to such certificates  containing the foregoing  legend,  until
the Distribution  Date, the Rights associated with the Common Shares represented
by such  certificates  shall be evidenced by such  certificates  alone,  and the
surrender  for  transfer  of any such  certificate  shall  also  constitute  the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Company  purchases  or acquires  any Common  Shares after the
Record Date but prior to the Distribution  Date, any Rights associated with such
Common Shares shall be deemed canceled 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(c),  the omission of a
legend shall not affect the  enforceability of any part of this Rights Agreement
or the rights of any holder of the Rights.

SECTION 4. FORM OF RIGHT CERTIFICATES.

     (a) The Right  Certificates (and the form of election to purchase Preferred
Shares,  the form of assignment and the form of  certification  to be printed on
the reverse thereof) shall be substantially the same as Exhibit B hereto and may
have such marks of identification or designation and such legends,  summaries or
endorsements  printed thereon as the Company may deem appropriate and as are not
inconsistent  with the  provisions of this  Agreement,  or as may be required to
comply with any  applicable  law or with any rule or  regulation  made  pursuant
thereto or with any rule or regulation of any stock exchange or quotation system
on which the  Rights  may from time to time be  listed,  or to conform to usage.
Subject  to  the  provisions  of  Sections  7,  11  and  22  hereof,  the  Right
Certificates  shall  entitle the holders  thereof to purchase such number of one
one-hundredths  of a Preferred  Share as shall be set forth therein at the price
per one  one-hundredth  of a Preferred  Share set forth  therein (the  "Purchase
Price"),  but the number of such one one-hundredths of a Preferred Share and the
Purchase Price shall be subject to adjustment as provided herein.

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

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



                                       6
<PAGE>


     The provisions of Section  11(a)(ii)  hereof shall be operative  whether or
not the foregoing legend is contained on any such Right Certificate.

SECTION 5.  COUNTERSIGNATURE  AND REGISTRATION.  The Right Certificates shall be
executed  on behalf of the  Company  by its  Chairman  of the  Board,  its Chief
Executive  Officer,  its  President,  its Vice Chairman of the Board,  its Chief
Financial  Officer,  or  any of  its  Vice  Presidents,  either  manually  or by
facsimile  signature,  shall  have  affixed  thereto  the  Company's  seal  or a
facsimile  thereof,  and shall be  attested  by the  Secretary  or an  Assistant
Secretary of the Company,  either manually or by facsimile signature.  The Right
Certificates  shall be manually  countersigned by the Rights Agent and shall not
be valid  for any  purpose  unless  countersigned.  In case any  officer  of the
Company  who shall have signed any of the Right  Certificates  shall cease to be
such  officer of the Company  before  countersignature  by the Rights  Agent and
issuance and delivery by the Company, such Right Certificates, nevertheless, may
be  countersigned  by the Rights  Agent and issued and  delivered by the Company
with the same  force and  effect as though  the  person  who  signed  such Right
Certificates  had not ceased to be such  officer of the  Company;  and any Right
Certificate  may be signed on behalf of the  Company by any person  who,  at the
actual  date of the  execution  of such  Right  Certificate,  shall  be a proper
officer of the Company to sign such Right  Certificate,  although at the date of
the execution of this Agreement any such person was not such an officer.

     Following the Distribution  Date, the Rights Agent will keep or cause to be
kept, at its office  designated  for such purpose,  books for  registration  and
transfer of the Right Certificates  issued hereunder.  Such books shall show the
names and addresses of the  respective  holders of the Right  Certificates,  the
number of Rights evidenced on its face by each of the Right Certificates and the
date of each of the Right Certificates.

SECTION 6. TRANSFER,  SPLIT UP, COMBINATION AND EXCHANGE OF RIGHT  CERTIFICATES;
MUTILATED,  DESTROYED,  LOST  OR  STOLEN  RIGHT  CERTIFICATES.  Subject  to  the
provisions of Section  11(a)(ii),  Section 14 and Section 24 hereof, at any time
after the Close of Business  on the  Distribution  Date,  and at or prior to the
Close of Business on the earlier of the Redemption Date or the Final  Expiration
Date, any Right Certificate or Right Certificates may be transferred,  split up,
combined or  exchanged  for another  Right  Certificate  or Right  Certificates,
entitling the registered holder to purchase a like number of one  one-hundredths
of a Preferred Share as the Right Certificate or Right Certificates  surrendered
then  entitled  such  holder to  purchase.  Any  registered  holder  desiring to
transfer,  split  up,  combine  or  exchange  any  Right  Certificate  or  Right
Certificates  shall make such request in writing  delivered to the Rights Agent,
and  shall  surrender  the  Right  Certificate  or  Right   Certificates  to  be
transferred,  split up,  combined or exchanged at the 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 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 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,  subject to Section 11(a)(ii),  Section 14 and
Section 24 hereof,  countersign  and  deliver to the person  entitled  thereto a
Right  Certificate or Right  Certificates,  as the case may be, as so requested.
The  Company  may  require  payment  of a


                                       7
<PAGE>


sum  sufficient to cover any tax or  governmental  charge that may be imposed in
connection  with any  transfer,  split  up,  combination  or  exchange  of Right
Certificates.

     Upon  receipt by the  Company and the Rights  Agent of evidence  reasonably
satisfactory  to them of the loss,  theft,  destruction or mutilation of a Right
Certificate,  and,  in case of  loss,  theft or  destruction,  of  indemnity  or
security  reasonably  satisfactory  to  them,  and,  at the  Company's  request,
reimbursement  to the Company and the Rights  Agent of all  reasonable  expenses
incidental  thereto,  and upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated,  the Company will issue, execute and deliver
a new Right  Certificate of like tenor to the Rights Agent for  countersignature
and delivery to the registered  holder in lieu of the Right Certificate so lost,
stolen, destroyed or mutilated.

     Notwithstanding  any other  provisions  hereof,  the Company and the Rights
Agent may amend this Rights  Agreement to provide for  uncertificated  Rights in
addition to or in place of Rights evidenced by Rights Certificates.

SECTION 7. EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS.

     (a) The registered  holder of any Right Certificate may exercise the Rights
evidenced  thereby (except as otherwise  provided herein) in whole or in part at
any time after the  Distribution  Date upon surrender of the Right  Certificate,
with the form of election to purchase on the reverse side thereof duly executed,
to the  Rights  Agent at the  office of the  Rights  Agent  designated  for such
purpose,  together with payment of the Purchase Price for each one one-hundredth
of a Preferred Share (or such other number of shares or other  securities) as to
which the Rights are exercised,  at or prior to the earliest of (i) the Close of
Business on May 3, 2009 (the "Final  Expiration  Date"),  (ii) the time at which
the Rights are  redeemed  as  provided  in  Section 23 hereof  (the  "Redemption
Date"),  or (iii) the time at which such  Rights are  exchanged  as  provided in
Section 24 hereof.

     (b) The purchase price (the "Purchase Price") for each one one-hundredth of
a Preferred  Share pursuant to the exercise of a Right shall initially be $40.00
and shall be subject to adjustment  from time to time as provided in Sections 11
and 13 hereof  and shall be  payable  in lawful  money of the  United  States of
America in accordance with paragraph (c) below.

     (c) Upon receipt of a Right Certificate  representing  exercisable  Rights,
with the form of election to purchase duly  executed,  accompanied by payment of
the  Purchase  Price for the shares to be  purchased  and an amount equal to any
applicable  transfer  tax  required  to be paid  by the  holder  of  such  Right
Certificate in accordance  with Section 9 hereof by certified  check,  cashier's
check, bank draft or money order payable to the order of the Company, the Rights
Agent shall thereupon  promptly (i) (A) requisition  from any transfer agent for
the  Preferred  Shares  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,  in its sole  discretion,
shall have elected to deposit the Preferred Shares issuable upon exercise of the
Rights  hereunder  into a  depository,  requisition  from the  depositary  agent
depositary  receipts  representing  such  number  of  one  one-hundredths  of  a
Preferred  Share as are to be  purchased  (in which  case  certificates  for the
Preferred Shares represented by such receipts shall be deposited by


                                       8
<PAGE>


the transfer agent with the depositary agent) and the Company hereby directs the
depositary agent to comply with such request, (ii) when appropriate, requisition
from the Company the amount of cash to be paid in lieu of issuance of fractional
shares in  accordance  with  Section  14  hereof,  (iii)  after  receipt of such
certificates or depositary  receipts,  cause the same to be delivered to or upon
the order of the registered holder of such Right Certificate, registered in such
name or names as may be  designated  by such  holder and (iv) when  appropriate,
after receipt,  deliver such cash to or upon the order of the registered  holder
of such Right  Certificate.  In the event that the Company is obligated to issue
securities of the Company other than Preferred Shares  (including Common Shares)
of the  Company  pursuant to Section  11(a)  hereof,  the Company  will make all
arrangements   necessary  so  that  such  other  securities  are  available  for
distribution by the Rights Agent, if and when appropriate.

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

     (d) In case the registered  holder of any Right  Certificate shall exercise
fewer than all the Rights evidenced thereby, a new Right Certificate  evidencing
Rights  equivalent to the Rights  remaining  unexercised  shall be issued by the
Rights Agent to the registered  holder of such Right  Certificate or to his duly
authorized assigns, subject to the provisions of Section 14 hereof.

     (e) The Company  covenants and agrees that it will cause to be reserved and
kept  available  out of its  authorized  and  unissued  Preferred  Shares or any
Preferred Shares held in its treasury,  the number of Preferred Shares that will
be  sufficient  to permit  the  exercise  in full of all  outstanding  Rights in
accordance with this Section 7.

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

SECTION  8.  CANCELLATION  AND  DESTRUCTION  OF RIGHT  CERTIFICATES.  All  Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for  cancellation or in canceled form,
or, if delivered or  surrendered  to the Rights Agent,  shall be canceled by it,
and no Right  Certificates  shall be issued in lieu thereof  except as expressly
permitted by any of the provisions of this Agreement.  The Company shall deliver
to the Rights Agent for cancellation and retirement,  and the Rights Agent shall
so cancel and retire, any other



                                       9

Right  Certificate  purchased or acquired by the Company otherwise than upon the
exercise thereof. The Rights Agent shall deliver all canceled Right Certificates
to the Company approximately one and one-half years after the cancellation date,
or shall,  at the written  request of the Company,  destroy such canceled  Right
Certificates,  and in such case  shall  deliver  a  certificate  of  destruction
thereof to the Company.

SECTION 9.  AVAILABILITY OF PREFERRED  SHARES.  The Company covenants and agrees
that so long as the Preferred  Shares (and,  after the time a person  becomes an
Acquiring  Person,  Common  Shares or any other  securities)  issuable  upon the
exercise  of the Rights may be listed on any  national  securities  exchange  or
quotation  system,  the Company  shall use its best  efforts to cause,  from and
after such time as the Rights become  exercisable,  all shares reserved for such
issuance to be listed on such exchange or quotation  system 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 (or Common  Shares and other
securities,  as the case may be) delivered upon exercise of Rights shall, at the
time of delivery  of the  certificates  for such  Preferred  Shares  (subject to
payment of the Purchase  Price),  be duly and validly  authorized and issued and
fully paid and nonassessable shares or other securities.

     The  Company  further  covenants  and agrees  that it will pay when due and
payable any and all federal and state  transfer  taxes and charges  which may be
payable in respect of the issuance or delivery of the Right  Certificates  or of
any  Preferred  Shares  upon the  exercise  of Rights.  The  Company  shall not,
however,  be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right  Certificates  to a person other than,  or the
issuance or delivery of  certificates  or depositary  receipts for the Preferred
Shares  in a name  other  than  that of,  the  registered  holder  of the  Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any  certificates or depositary  receipts for Preferred Shares upon the exercise
of any  Rights  until  any such tax  shall  have  been  paid (any such tax being
payable by the holder of such Right  Certificate  at the time of  surrender)  or
until it has been established to the Company's  reasonable  satisfaction that no
such tax is due.

     As soon as practicable  after the Distribution  Date, the Company shall use
its best efforts to:

          (i) prepare and file a registration statement under the Securities Act
     of 1933,  as  amended  (the  "Act"),  with  respect  to the  Rights and the
     securities  purchasable upon exercise of the Rights on an appropriate form,
     will use its best  efforts to cause such  registration  statement to become
     effective  as soon as  practicable  after such filing and will use its best
     efforts to cause such  registration  statement to remain  effective (with a
     prospectus  at all times  meeting  the  requirements  of the Act) until the
     Final Expiration Date; and

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



                                       10

SECTION  10.  PREFERRED  SHARES  RECORD  DATE.  Each  person  in whose  name any
certificate for Preferred Shares or other securities is issued upon the exercise
of Rights  shall for all  purposes be deemed to have become the holder of record
of the Preferred  Shares or other  securities  represented  thereby on, and such
certificate shall be dated, the date upon which the Right Certificate evidencing
such Rights was duly  surrendered  with the forms of election and  certification
duly  executed and payment of the Purchase  Price (and any  applicable  transfer
taxes)  was made;  provided,  however,  that if the date of such  surrender  and
payment is a date upon which the Preferred Shares or other  securities  transfer
books of the Company are closed,  such person shall be deemed to have become the
record holder of such shares on, and such  certificate  shall be dated, the next
succeeding  Business  Day on which  the  Preferred  Shares  or other  securities
transfer  books of the  Company  are open.  Prior to the  exercise of the Rights
evidenced  thereby,  the holder of a Right  Certificate,  as such,  shall not be
entitled  to any  rights of a holder of  Preferred  Shares  for which the Rights
shall be  exercisable,  including,  without  limitation,  the right to vote,  to
receive dividends or other  distributions or to exercise any preemptive  rights,
and shall not be  entitled  to  receive  any  notice of any  proceedings  of the
Company, except as provided herein.

SECTION 11. ADJUSTMENT OF PURCHASE PRICE,  NUMBER OF SHARES OR NUMBER OF RIGHTS.
The Purchase Price, the number of Preferred Shares covered by each Right and the
number of Rights  outstanding  are  subject to  adjustment  from time to time as
provided in this Section 11.

     (a)

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



                                       11
<PAGE>


          (ii)  Subject  to Section  24 hereof  and the  provisions  of the next
     paragraph of this Section  11(a)(ii),  in the event any Person shall become
     an Acquiring Person,  each holder of a Right shall, for a period of 60 days
     after the later of such time any Person becomes an Acquiring  Person or the
     effective  date of an  appropriate  registration  statement  under  the Act
     pursuant to Section 9 hereof (provided,  however that, if at any time prior
     to the  expiration or  termination of the Rights there shall be a temporary
     restraining order, a preliminary  injunction,  an injunction,  or temporary
     suspension  by the Board of Directors,  or similar  obstacle to exercise of
     the Rights (the "Injunction")  which prevents exercise of the Rights, a new
     60-day period shall commence on the date the Injunction is removed), have a
     right  to  receive,  upon  exercise  thereof  at a price  equal to the then
     current Purchase Price multiplied by the number of one  one-hundredths of a
     Preferred Share for which a Right is then  exercisable,  in accordance with
     the terms of this Agreement and in lieu of Preferred Shares, such number of
     Common  Shares as shall equal the result  obtained by (A)  multiplying  the
     then  current  Purchase  Price by the  number  of one  one-hundredths  of a
     Preferred  Share for which a Right is then  exercisable  and dividing  that
     product by (B) 50% of the then current per share market price of the Common
     Shares  (determined  pursuant  to  Section  11(d)  hereof) on the date such
     Person  became  an  Acquiring  Person;  provided,   however,  that  if  the
     transaction  that would otherwise give rise to the foregoing  adjustment is
     also  subject  to the  provisions  of  Section  13  hereof,  then  only the
     provisions of Section 13 hereof shall apply and no adjustment shall be made
     pursuant  to this  Section  11(a)(ii).  In the event that any Person  shall
     become an Acquiring  Person and the Rights shall then be  outstanding,  the
     Company  shall not take any action  which would  eliminate  or diminish the
     benefits intended to be afforded by the Rights.

     Notwithstanding  anything in this Agreement to the contrary, from and after
the time any Person becomes an Acquiring Person,  any Rights  beneficially owned
by (i) such  Acquiring  Person or an Associate  or  Affiliate of such  Acquiring
Person,  (ii) a transferee of such Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee  after the Acquiring  Person became such, or
(iii) a  transferee  of such  Acquiring  Person  (or of any  such  Associate  or
Affiliate) who becomes a transferee prior to or concurrently  with the Acquiring
Person's  becoming  such and  receives  such  Rights  pursuant  to either  (A) a
transfer (whether or not for consideration) from the Acquiring Person to holders
of equity  interests  in such  Acquiring  Person or to any Person  with whom the
Acquiring  Person has any continuing  agreement,  arrangement  or  understanding
regarding the transferred  Rights or (B) a transfer which the Board of Directors
of the Company has determined is part of a plan,  arrangement  or  understanding
which  has as a  primary  purpose  or  effect  the  avoidance  of  this  Section
11(a)(ii),  shall become null and void without any further  action and no holder
of such Rights  shall have any rights  whatsoever  with  respect to such Rights,
whether  under any provision of this  Agreement or otherwise.  The Company shall
use all  reasonable  efforts  to  insure  that the  provisions  of this  Section
11(a)(ii) and Section 4(b) hereof are complied with, but shall have no liability
to any holder of Right  Certificates  or other Person as a result of its failure
to  make  any  determinations  with  respect  to  an  Acquiring  Person  or  its
Affiliates,  Associates or transferees hereunder.  No Right Certificate shall be
issued at any time upon the transfer of any Rights to an Acquiring  Person whose
Rights  would be void  pursuant to the  preceding  sentence or any  Associate or
Affiliate  thereof or to any  nominee of such  Acquiring  Person,  Associate  or
Affiliate;  and any Right Certificate delivered to



                                       12
<PAGE>


the Rights Agent for transfer to an Acquiring  Person whose Rights would be void
pursuant to the preceding sentence shall be canceled.

          (iii) In lieu of issuing  Common  Shares in  accordance  with  Section
     11(a)(ii) hereof,  the Company may, if a majority of the Board of Directors
     then in office  determines that such action is necessary or appropriate and
     not contrary to the  interests of holders of Rights,  elect to (and, in the
     event that the Board of Directors  has not  exercised  the  exchange  right
     contained  in Section  24(c) hereof and there are not  sufficient  treasury
     shares and authorized but unissued  Common Shares to permit the exercise in
     full of the Rights in accordance with the foregoing  subparagraph (ii), the
     Company shall) take all such action as may be necessary to authorize, issue
     or pay,  upon the  exercise  of the  Rights,  cash  (including  by way of a
     reduction of the Purchase Price), property, Common Shares, other securities
     or any combination  thereof having an aggregate value equal to the value of
     the Common  Shares which  otherwise  would have been  issuable  pursuant to
     Section  11(a)(ii)  hereof,  which aggregate value shall be determined by a
     nationally recognized investment banking firm selected by a majority of the
     Board of Directors then in office. For purposes of the preceding  sentence,
     the value of the Common  Shares  shall be  determined  pursuant  to Section
     11(d)  hereof.  Any such  election by the Board of  Directors  must be made
     within 60 days  following the date on which the event  described in Section
     11(a)(ii) hereof shall have occurred. Following the occurrence of the event
     described in Section 11(a)(ii) hereof, a majority of the Board of Directors
     then in office may suspend the exercisability of the Rights for a period of
     up to 60 days  following  the date on which the event  described in Section
     11(a)(ii) hereof shall have occurred to the extent that such directors have
     not  determined  whether to exercise  their  rights of election  under this
     Section 11(a)(iii). In the event of any such suspension,  the Company shall
     issue a public  announcement  stating that the exercisability of the Rights
     has been temporarily suspended.

     (b) In case the Company shall fix a record date for the issuance of rights,
options  or  warrants  to all  holders of  Preferred  Shares  entitling  them to
subscribe  for  or  purchase   Preferred  Shares  (or  shares  having  the  same
designations  and the powers,  preferences and rights,  and the  qualifications,
limitations and  restrictions  as the Preferred  Shares  ("equivalent  preferred
shares"))  or  securities   convertible  into  Preferred  Shares  or  equivalent
preferred  shares at a price per Preferred  Share or equivalent  preferred share
(or  having a  conversion  price  per  share,  if a  security  convertible  into
Preferred Shares or equivalent  preferred shares) less than the then current per
share market price of the Preferred Shares (as such term is hereinafter defined)
on such record date,  the Purchase  Price to be in effect after such record date
shall be  determined by  multiplying  the Purchase  Price in effect  immediately
prior to such  record date by a fraction,  the  numerator  of which shall be the
number of Preferred  Shares  outstanding  on such record date plus the number of
Preferred  Shares  which the  aggregate  offering  price of the total  number of
Preferred Shares and/or equivalent preferred shares so to be offered (and/or the
aggregate  initial  conversion  price  of the  convertible  securities  so to be
offered)  would  purchase at such current  market price and the  denominator  of
which shall be the number of Preferred  Shares  outstanding  on such record date
plus the number of  additional  Preferred  Shares  and/or  equivalent  preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible);  provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the  aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right. In case such subscription price may be paid
in a



                                       13
<PAGE>


consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent.  Preferred  Shares owned by or held for the account
of the  Company  shall not be deemed  outstanding  for the  purpose  of any such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued,  the  Purchase  Price shall be adjusted to be the  Purchase  Price which
would then be in effect if such record date had not been fixed.

     (c) In case the  Company  shall  fix a  record  date  for the  making  of a
distribution  to all  holders  of  the  Preferred  Shares  (including  any  such
distribution  made in  connection  with a  consolidation  or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription  rights or warrants  (excluding those referred
to in Section  11(b)  hereof),  the  Purchase  Price to be in effect  after such
record date shall be  determined  by  multiplying  the Purchase  Price in effect
immediately  prior to such  record date by a fraction,  the  numerator  of which
shall be the then  current per share market  price of the  Preferred  Shares (as
such term is  hereinafter  defined)  on such record  date,  less the fair market
value (as  determined  in good faith by the Board of  Directors  of the Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent) of the  portion  of the  assets or  evidences  of  indebtedness  so to be
distributed  or of  such  subscription  rights  or  warrants  applicable  to one
Preferred  Share and the  denominator  of which shall be such  current per share
market price of the Preferred Shares; provided,  however, that in no event shall
the  consideration  to be paid upon the  exercise  of one Right be less than the
aggregate  par value of the shares of capital  stock of the Company to be issued
upon exercise of one Right. Such adjustments shall be made successively whenever
such a record date is fixed;  and in the event that such  distribution is not so
made,  the Purchase Price shall again be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

     (d)

          (i) For the purpose of any  computation  hereunder,  the  "current per
     share market price" of any security (a  "Security"  for the purpose of this
     Section  11(d)(i))  on any date  shall be deemed to be the  average  of the
     daily  closing  prices per share of such  Security  for the 30  consecutive
     Trading Days (as such term is  hereinafter  defined)  immediately  prior to
     such date; provided,  however, that in the event that the current per share
     market price of the Security is  determined  during a period  following the
     announcement  by  the  issuer  of  such  Security  of  (A)  a  dividend  or
     distribution  on such  Security  payable  in  shares  of such  Security  or
     securities   convertible   into  such  shares,   or  (B)  any  subdivision,
     combination or reclassification of such Security or securities  convertible
     into such shares, or (C) any subdivision,  combination or  reclassification
     of such  Security and prior to the  expiration of 30 Trading Days after the
     ex-dividend date for such dividend or distribution,  or the record date for
     such subdivision,  combination or reclassification,  then, and in each such
     case, the current per share market price shall be appropriately adjusted to
     reflect the current market price per share equivalent of such Security. The
     closing  price for each day shall be the last sale price,  regular way, or,
     in case no such sale takes  place on such day,  the  average of the closing
     bid and asked  prices,  regular  way,  in 



                                       14
<PAGE>


     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 as reported on the Nasdaq  National Market
     or, if the  Security is not listed or  admitted to trading on any  national
     securities  exchange or reported on the Nasdaq  National  Market,  the last
     quoted  price or, if not so  quoted,  the  average  of the high bid and low
     asked prices in the  over-the-counter  market,  as reported by the National
     Association  of  Securities  Dealers,   Inc.  Automated  Quotations  System
     ("Nasdaq")  or such other  system then in use,  or, if on any such date the
     Security is not quoted by any such organization, the average of the closing
     bid and asked prices as furnished by a  professional  market maker making a
     market in the  Security  selected by the Board of  Directors of the Company
     or, if on any such date no professional  market maker is making a market in
     the  Security,  the  price as  determined  in good  faith  by the  Board of
     Directors.  The term  "Trading Day" shall mean a day on which the principal
     national securities exchange on which the Security is listed or admitted to
     trading is open for the  transaction of business or, if the Security is not
     listed or  admitted  to  trading on any  national  securities  exchange,  a
     Business Day.

          (ii) For the purpose of any  computation  hereunder,  the "current per
     share  market  price"  of the  Preferred  Shares  shall  be  determined  in
     accordance  with the method set forth in Section  11(d)(i)  hereof.  If the
     Preferred  Shares are not  publicly  traded,  the "current per share market
     price"  of the  Preferred  Shares  shall be  conclusively  deemed to be the
     current per share market price of the Common Shares as determined  pursuant
     to Section  11(d)(i)  hereof  (appropriately  adjusted to reflect any stock
     split,  stock  dividend  or similar  transaction  occurring  after the date
     hereof)  multiplied  by one hundred.  If neither the Common  Shares nor the
     Preferred  Shares are  publicly  held or so listed or traded,  "current per
     share market  price" shall mean the fair value per share as  determined  in
     good faith by the Board of Directors of the  Company,  whose  determination
     shall be described in a statement filed with the Rights Agent.

     (e) No  adjustment  in the  Purchase  Price shall be  required  unless such
adjustment  would require an increase or decrease of at least 1% in the Purchase
Price;  provided,  however, that any adjustments which by reason of this Section
11(e) are not  required  to be made  shall be  carried  forward  and taken  into
account in any subsequent  adjustment.  All  calculations  under this Section 11
shall be made to the  nearest  cent or to the  nearest  one  one-hundredth  of a
Preferred Share or one ten-thousandth of any other share or security as the case
may be. Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the  transaction  which requires such  adjustment or (ii)
the date of the expiration of the right to exercise any Rights.

     (f) If as a result of an adjustment  made pursuant to Section 11(a) hereof,
the holder of any Right  thereafter  exercised  shall become entitled to receive
any  shares  of  capital  stock of the  Company  other  than  Preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right shall be subject to adjustment  from time to time in a manner and on terms
as nearly  equivalent  as  practicable  to the  provisions  with  respect to the
Preferred  Shares  contained in Sections 11(a) through 11(c) hereof,  inclusive,
and the  provisions  of Sections 7, 9, 



                                       15
<PAGE>


10, 13 and 14 hereof with  respect to the  Preferred  Shares shall apply on like
terms to any such other shares.

     (g)  All  Rights  originally  issued  by  the  Company  subsequent  to  any
adjustment  made to the Purchase  Price  hereunder  shall  evidence the right to
purchase,  at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

     (h) Unless the Company  shall have  exercised  its  election as provided in
Section 11(i) hereof,  upon each adjustment of the Purchase Price as a result of
the  calculations  made in Section 11(b) and Section  11(c)  hereof,  each Right
outstanding  immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase,  at the adjusted  Purchase Price, that number of
one  one-hundredths  of  a  Preferred  Share  (calculated  to  the  nearest  one
one-millionth  of a Preferred  Share) obtained by (i) multiplying (x) the number
of one  one-hundredths of a 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.

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

     (j)  Irrespective  of any adjustment or change in the Purchase Price or the
number of one  one-hundredths of a Preferred Share issuable upon the exercise of
the  Rights,  the Right


                                       16
<PAGE>


Certificates  theretofore  and  thereafter  issued may  continue  to express the
Purchase Price and the number of one  one-hundredths  of a Preferred Share which
were expressed in the initial Right Certificates issued hereunder.

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

     (l) In any case in which this Section 11 shall  require that an  adjustment
in the  Purchase  Price be made  effective  as of a record  date for a specified
event,  the Company may elect to defer  until the  occurrence  of such event the
issuing  to the holder of any Right  exercised  after  such  record  date of the
Preferred  Shares and other capital stock or securities of the Company,  if any,
issuable upon such  exercise on the basis of the Purchase  Price in effect prior
to such adjustment;  provided,  however,  that the Company shall deliver to such
holder a due bill or other appropriate instrument evidencing such holder's right
to receive such  additional  shares upon the  occurrence of the event  requiring
such adjustment.

     (m) The Company covenants and agrees that, after the Distribution  Date, it
will not,  except as  permitted  by Section  23 or  Section 27 hereof,  take (or
permit any  Subsidiary  to take) any action the purpose of which is to, or if at
the time such action is taken it is  reasonably  foreseeable  that the effect of
such action is to, materially  diminish or eliminate the benefits intended to be
afforded by the Rights.  Any such action taken by the Company  during any period
after any Person becomes an Acquiring Person but prior to the Distribution  Date
shall be null and void  unless such  action  could be taken  under this  Section
11(m) from and after the Distribution Date.

     (n)  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 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 hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares shall not be taxable to such shareholders.

     (o) In the  event  that at any time  after the date of this  Agreement  and
prior to the  Distribution  Date,  the  Company  shall  (i)  declare  or pay any
dividend  on the  Common  Shares  payable  in  Common  Shares  or (ii)  effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or otherwise  than by payment of  dividends in Common  Shares)
into a greater or lesser number of Common Shares,  then in any such case (A) the
number of one  one-hundredths  of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one  one-hundredths of a Preferred Share so purchasable  immediately prior to
such event by a fraction,  the numerator of which is the 


                                       17
<PAGE>


number  of Common  Shares  outstanding  immediately  before  such  event and the
denominator  of which is the  number of Common  Shares  outstanding  immediately
after such event, and (B) each Common Share  outstanding  immediately after such
event  shall have issued  with  respect to it that  number of Rights  which each
Common Share outstanding immediately prior to such event had issued with respect
to it.  The  adjustments  provided  for in  this  Section  11(o)  shall  be made
successively whenever such a dividend is declared or paid or such a subdivision,
combination or consolidation is effected.

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

SECTION 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES. Whenever
an  adjustment  is made as provided  in  Sections 11 and 13 hereof,  the Company
shall promptly (a) prepare a certificate  setting forth such  adjustment,  and a
brief statement of the facts accounting for such  adjustment,  (b) file with the
Rights Agent and with each transfer agent for the Common Shares 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 hereof.  The Rights
Agent shall be fully  protected  in relying on any such  certificate  and on any
adjustment  therein  contained and shall not be deemed to have  knowledge of any
adjustment unless and until it shall have received such certificate.

SECTION  13.  CONSOLIDATION,  MERGER OR SALE OR  TRANSFER  OF ASSETS OR  EARNING
POWER.

     (a) In the event  that,  following  the  Shares  Acquisition  Date or, if a
Transaction is proposed,  the Distribution Date,  directly or indirectly (x) the
Company  shall  consolidate  with,  or  merge  with  and  into,  any  Interested
Shareholder,  or if in such merger or consolidation  all holders of Common Stock
are not treated alike,  any other Person,  (y) any Interested  Person,  or if in
such merger or consolidation  all holders of Common Stock are not treated alike,
any other Person shall consolidate with the Company,  or merge with and into the
Company,  and the Company shall be the  continuing or surviving  corporation  of
such merger (other than, in the case of either  transaction  described in (x) or
(y), a merger or  consolidation  which would  result in all of the voting  power
represented  by the  securities  of the Company  outstanding  immediately  prior
thereto  continuing to represent  (either by remaining  outstanding  or by being
converted  into  securities  of the  surviving  entity) all of the voting  power
represented  by  the  securities  of  the  Company  or  such  surviving   entity
outstanding  immediately  after such merger or consolidation  and the holders of
such securities not having changed as a result of such merger or consolidation),
or (z) the Company shall sell, mortgage or otherwise transfer (or one or more of
its subsidiaries  shall sell,  mortgage or otherwise  transfer),  in one or more
transactions, assets or earning power aggregating more than 50% of the assets or
earning  power of the  Company  and its  subsidiaries  (taken as a whole) to any
Interested Shareholder or Shareholders, or if in such transaction all holders of
Common Stock are not treated alike, any other Person, (other than the Company or
any  Subsidiary  of the  Company  in one or  more  transactions  each  of  which
individually  and the aggregate does not violate Section 13(d) hereof) then, and
in each such case,  proper  provision



                                       18
<PAGE>


shall be made so that (i) each holder of a Right,  subject to Section  11(a)(ii)
hereof,  shall have the right to receive,  upon the exercise  thereof at a price
equal to the  then  current  Purchase  Price  multiplied  by the  number  of one
one-hundredths  of a Preferred  Share for which a Right is then  exercisable  in
accordance  with the terms of this  Agreement  and in lieu of Preferred  Shares,
such number of freely  tradeable  Common Shares of the Principal  Party (as such
term is hereinafter  defined),  free and clear of liens, rights of call or first
refusal,  encumbrances or other adverse claims,  as shall be equal to the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-hundredths  of a  Preferred  Share  for  which a Right  is then  exercisable
(without taking into account any adjustment  previously made pursuant to Section
11(a)(ii)  hereof) and dividing  that product by (B) 50% of the then current per
share  market price of the Common  Shares of such  Principal  Party  (determined
pursuant  to  Section  11(d)  hereof)  on  the  date  of  consummation  of  such
consolidation,  merger,  sale or  transfer;  (ii)  such  Principal  Party  shall
thereafter  be liable for, and shall  assume,  by virtue of such  consolidation,
merger, sale or transfer, all the obligations and duties of the Company pursuant
to this Agreement;  (iii) the term "Company" shall thereafter be deemed to refer
to such Principal Party, it being  specifically  intended that the provisions of
Section 11 hereof shall apply to such Principal  Party;  and (iv) such Principal
Party shall take such steps (including, but not limited to, the reservation of a
sufficient  number of shares of its Common Shares in  accordance  with Section 9
hereof) in connection with such  consummation as may be necessary to assure that
the provisions  hereof shall  thereafter be applicable,  as nearly as reasonably
may be,  in  relation  to its  Common  Shares  thereafter  deliverable  upon the
exercise of the Rights.

     (b) "Principal Party" shall mean:

          (i) in the case of any  transaction  described in clause (x) or (y) of
     the first  sentence of Section 13(a) hereof,  the Person that is the issuer
     of any securities  into which Common Shares are converted in such merger or
     consolidation,  and if no securities are so issued,  the Person that is the
     other party to the merger or consolidation (or, if applicable, the Company,
     if it is the surviving corporation); and

          (ii) in the  case of any  transaction  described  in (z) of the  first
     sentence of Section  13(a) hereof,  the Person that is the party  receiving
     the greatest portion of the assets or earning power transferred pursuant to
     such transaction or transactions;

     provided,  however,  that in any  case,  (1) if the  Common  Shares of such
Person are not at such time and have not been  continuously  over the  preceding
12-month period registered under Section 12 of the Exchange Act, and such Person
is a direct or indirect  subsidiary  or Affiliate  of another  Person the Common
Shares of which are and have been so registered,  "Principal  Party" shall refer
to  such  other  Person;  (2)  if  such  Person  is a  subsidiary,  directly  or
indirectly,  or Affiliate of more than one Person,  the Common  Shares of two or
more of which are and have been so registered,  "Principal Party" shall refer to
whichever of such Persons is the issuer of the Common Shares having the greatest
aggregate market value; and (3) 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 (1) and (2) above shall
apply to each of the  chains of  ownership  having  an  interest  in such  joint
venture  as if such  party  were a  "subsidiary"  of  both or all of such  joint
venturers  and  the  Principal  Parties  in  each  such  chain



                                       19
<PAGE>


shall  bear the  obligations  set forth in this  Section 13 in the same ratio as
their  direct or  indirect  interests  in such  Person bear to the total of such
interests.

     (c) The Company shall not consummate any such  consolidation,  merger, sale
or  transfer  unless  the  Principal  Party  shall have a  sufficient  number of
authorized  Common  Shares that have not been issued or reserved for issuance to
permit the exercise in full of the Rights in accordance with this Section 13 and
unless prior thereto the Company and each Principal  Party and each other Person
who may become a Principal Party as a result of such consolidation, merger, sale
or  transfer  shall  have (i)  executed  and  delivered  to the  Rights  Agent a
supplemental  agreement  providing for the terms set forth in paragraphs (a) and
(b) of this  Section 13 and (ii)  prepared,  filed and had  declared  and remain
effective a registration  statement under the Act on the  appropriate  form with
respect to the Rights and the securities exercisable upon exercise of the Rights
and  further  providing  that,  as soon as  practicable  after  the  date of any
consolidation,  merger, sale or transfer of assets mentioned in paragraph (a) of
this Section 13, the Principal Party at its own expense will:

          (i) cause the registration statement under the Act with respect to the
     Rights and the  securities  purchasable  upon  exercise of the Rights on an
     appropriate  form to  remain  effective  (with a  prospectus  at all  times
     meeting the requirements of the Act) until the Final Expiration Date;

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

          (iii) list the Rights and the securities  purchasable upon exercise of
     the Rights on each national  securities exchange on which the Common Shares
     were listed prior to the consummation of such  consolidation,  merger, sale
     or transfer of assets or on the Nasdaq National Market if the Common Shares
     were listed on the Nasdaq National Market or, if the Common Shares were not
     listed on a national  securities  exchange  or the Nasdaq  National  Market
     prior to the consummation of such  consolidation,  merger, sale or transfer
     of assets, on a national securities exchange or the Nasdaq National Market;
     and

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

     The  provisions  of this  Section 13 shall  similarly  apply to  successive
mergers or consolidations or sales or other transfers.

     (d) After the Distribution  Date, the Company  covenants and agrees that it
shall not (i)  consolidate  with,  (ii)  merge  with or into,  or (iii)  sell or
transfer to, in one or more  transactions,  assets or earning power  aggregating
more than 50% of the assets or earning power of the Company and its subsidiaries
taken as a whole,  any other Person (other than a Subsidiary of the Company in a
transaction which does not violate Section 11(m) hereof),  if (x) at the time of
or after  such  consolidation,  merger or sale  there are any  charter  or bylaw
provisions  or  any  rights,



                                       20
<PAGE>


warrants or other instruments or securities outstanding, agreements in effect or
any other action taken which would diminish or otherwise  eliminate the benefits
intended to be afforded  by the Rights or (y) prior to,  simultaneously  with or
immediately  after such  consolidation,  merger or sale, the shareholders of the
Person who constitutes,  or would constitute, the "Principal Party" for purposes
of Section 13(a) hereof shall have received a distribution of Rights  previously
owned by such Person or any of its Affiliates and Associates.  The Company shall
not consummate any such  consolidation,  merger,  sale or transfer  unless prior
thereto the Company and such other Person shall have  executed and  delivered to
the  Rights  Agent a  supplemental  agreement  evidencing  compliance  with this
Section 13(d).

SECTION 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

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

     (b) The  Company  shall not be  required to issue  fractions  of  Preferred
Shares (other than fractions which are integral  multiples of one  one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute  certificates
which  evidence  fractional  Preferred  Shares (other than  fractions  which are
integral  multiples of one  one-hundredth  of a Preferred  Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may, at the  election of the  Company,  be  evidenced  by  depositary  receipts;
provided,  however,  that holders of such depositary  receipts shall have all of
the designations and the powers, preferences and rights, and the qualifications,
limitations and restrictions 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



                                       21
<PAGE>


such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share. For the purposes of
this Section 14(b),  the current market value of a Preferred  Share shall be the
current per share market price of the Preferred  Shares (as determined  pursuant
to the  second  sentence  of  Section  11(d)(i)  hereof)  for  the  Trading  Day
immediately  prior to the date of such exercise (or, if not publicly traded,  in
accordance with Section 11(d)(ii) hereof).

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

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

SECTION 15. RIGHTS OF ACTION. All rights of action in respect of this Agreement,
excepting  the rights of action given to the Rights Agent under  Sections 18 and
20  hereof,  are  vested  in the  respective  registered  holders  of the  Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares) and any registered  holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares),  without the consent of the Rights
Agent  or of the  holder  of any  other  Right  Certificate  (or,  prior  to the
Distribution Date, of the Common Shares), may, in his own behalf and for his own
benefit,  enforce, and may institute and maintain any suit, action or proceeding
against  the Company to enforce,  or  otherwise  act in respect of, his right to
exercise the Rights  evidenced by such Right  Certificate in the manner provided
in such Right Certificate and in this Agreement.  Without limiting the foregoing
or  any  remedies  available  to  the  holders  of  Rights,  it is  specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and will be entitled to specific performance of
the  obligations  under,  and  injunctive  relief  against  actual or threatened
violations of the obligations of any Person subject to, this Agreement.  Holders
of Rights  shall be  entitled  to recover  the  reasonable  costs and  expenses,
including  attorneys  fees,  incurred  by  them in any  action  to  enforce  the
provisions of this Agreement.

SECTION 16.  AGREEMENT OF 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:



                                       22
<PAGE>


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

     (b) after the  Distribution  Date, the Right  Certificates are transferable
(subject to the provisions of this Rights  Agreement) only on the registry books
of the Rights Agent if surrendered at the principal  office of the Rights Agent,
duly endorsed or accompanied by a proper instrument of transfer; and

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

SECTION 17. RIGHT  CERTIFICATE  HOLDER NOT DEEMED A SHAREHOLDER.  No holder,  as
such, of any Right Certificate  shall be entitled to vote,  receive dividends or
be  deemed  for any  purpose  the  holder of the  Preferred  Shares or any other
securities  of the Company  which may at any time be issuable on the exercise of
the Rights  represented  thereby,  nor shall anything contained herein or in any
Right  Certificate  be  construed  to  confer  upon  the  holder  of  any  Right
Certificate,  as such,  any of the rights of a shareholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
shareholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
shareholders  (except as provided in Section 25 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Right  Certificate  shall  have  been  exercised  in  accordance  with the
provisions hereof.

SECTION 18. CONCERNING THE RIGHTS AGENT. The Company agrees to pay to the Rights
Agent  reasonable  compensation  for all services  rendered by it hereunder and,
from time to time, on demand of the Rights Agent,  its  reasonable  expenses and
counsel  fees  and  other  disbursements  incurred  in  the  administration  and
execution  of this  Agreement  and the exercise  and  performance  of its duties
hereunder.  The Company  also agrees to  indemnify  the Rights Agent for, and to
hold it harmless  against,  any loss,  liability,  or expense,  incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection  with the  acceptance
and  administration  of this  Agreement,  including  the costs and  expenses  of
defending against any claim of liability in the premises. The indemnity provided
herein shall survive the  expiration of the Rights and the  termination  of this
Agreement.

     The Rights Agent shall be protected and shall incur no liability for, or in
respect of any action taken,  suffered or omitted by it in connection  with, its
administration  of this  Agreement  in reliance  upon any Right  Certificate  or
certificate for the Preferred Shares or Common Shares or for other securities of
the  Company,   instrument  of  assignment  or  transfer,   power  of  attorney,
endorsement,   affidavit,  letter,  notice,  direction,   consent,  certificate,
statement,  or other  paper or  document  believed by it to be genuine and to be
signed, executed and, where necessary,  verified



                                       23
<PAGE>


or acknowledged,  by the proper person or persons,  or otherwise upon the advice
of counsel as set forth in Section 20 hereof.  In no case will the Rights  Agent
be liable for special,  indirect,  incidental or  consequential or consequential
loss or  damage  at any  kind  whatsoever  (including  but not  limited  to lost
profits), even if the Rights Agent has been advised of such loss or damage.

SECTION  19.  MERGER OR  CONSOLIDATION  OR CHANGE OF NAME OF RIGHTS  AGENT.  Any
corporation  into which the Rights  Agent or any  successor  Rights Agent may be
merged or with which it may be consolidated,  or any corporation  resulting from
any merger or  consolidation  to which the Rights Agent or any successor  Rights
Agent  shall  be a  party,  or any  corporation  succeeding  to the  shareholder
services or corporate trust business of the Rights Agent or any successor Rights
Agent,  shall be the successor to the Rights Agent under this Agreement  without
the  execution  or filing of any paper or any  further act on the part of any of
the  parties  hereto,  provided  that such  corporation  would be  eligible  for
appointment  as a  successor  Rights  Agent under the  provisions  of Section 21
hereof.  In case at the time such  successor  Rights Agent shall  succeed to the
agency created by this Agreement any of the Right  Certificates  shall have been
countersigned  but not delivered,  any such successor Rights Agent may adopt the
countersignature  of  the  predecessor  Rights  Agent  and  deliver  such  Right
Certificates  so  countersigned;  and in  case  at that  time  any of the  Right
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor  Rights Agent;  and in all such cases such
Right  Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

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

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

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

     (b)  Whenever in the  performance  of its duties under this  Agreement  the
Rights Agent shall deem it  necessary  or  desirable  that any fact or matter be
proved or  established  by the Company  prior to taking or suffering  any action
hereunder,  such fact or matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed)  may be deemed to be  conclusively  proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer,  the President,  the Chief Financial Officer,  any Vice
President,  the  Treasurer or the  Secretary of the Company and delivered to the
Rights Agent;  and such  certificate  shall be full



                                       24
<PAGE>


authorization to the Rights Agent for any action taken or suffered in good faith
by it under the provisions of this Agreement in reliance upon such certificate.

     (c) The Rights Agent shall be liable hereunder to the Company and any other
Person only for its own negligence, bad faith or willful misconduct.

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

     (e) The Rights  Agent shall not be under any  responsibility  in respect of
the validity of this Agreement or the execution and delivery  hereof (except the
due  execution  hereof by the Rights  Agent) or in respect  of the  validity  or
execution of any Right Certificate (except its  countersignature  thereof);  nor
shall it be  responsible  for any  breach  by the  Company  of any  covenant  or
condition contained in this Agreement or in any Right Certificate;  nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section  11(a)(ii) hereof) or any adjustment in
the terms of the  Rights  (including  the  manner,  method  or  amount  thereof)
provided for in Sections 3, 11, 13, 23 or 24 hereof,  or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right  Certificates after receipt
of a  certificate  pursuant  to  Section  12 hereof  describing  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  to  be  issued  pursuant  to  this  Agreement  or  any  Right
Certificate or as to whether any Preferred Shares will, when issued,  be validly
authorized and issued, fully paid and nonassessable.

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

     (g)  The  Rights  Agent  is  hereby   authorized  and  directed  to  accept
instructions  with respect to the  performance of its duties  hereunder from any
one of the Chairman of the Board,  the Chief Executive  Officer,  the President,
the Chief Financial Officer, any Vice President,  the Secretary or the Treasurer
of the  Company,  and to apply to such  officers for advice or  instructions  in
connection  with its duties,  and it shall not be liable for any action taken or
suffered by it in good faith in accordance with instructions of any such officer
or for any delay in acting while waiting for those instructions. Any application
by the Rights Agent for written instructions from the Company may, at the option
of the Rights  Agent,  set forth in writing  any action  proposed to be taken or
omitted by the Rights Agent with respect to its duties or obligations under this
Agreement  and the date on and/or  after  which  such  action  shall be taken or
omitted and the Rights Agent shall not be liable for any action taken or omitted
in accordance with a proposal  included in any such  application on or after the
date  specified  therein  (which date shall not be less than three Business Days
after the date indicated in such application  unless any such officer shall have
consented in writing to an earlier date) unless, prior to taking or omitting



                                       25
<PAGE>


any such action, the Rights Agent has received written  instructions in response
to such application specifying the action to be taken or omitted.

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

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

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

     (k) If, with  respect to any Right  Certificate  surrendered  to the Rights
Agent  for  exercise  or  transfer,  the  certificate  attached  to the  form of
assignment  or form of  election to  purchase,  as the case may be, has not been
executed,  the Rights  Agent shall not take any further  action with  respect to
such requested exercise of transfer without first consulting with the Company.

SECTION 21.  CHANGE OF RIGHTS AGENT.  The Rights Agent or any  successor  Rights
Agent may resign and be discharged  from its duties under this Agreement upon 30
days' notice in writing mailed to the Company and to each transfer agent for the
Common Shares or Preferred  Shares by registered or certified  mail,  and to the
holders of the Right  Certificates  by first-class  mail. The Company may remove
the Rights Agent or any successor  Rights Agent upon 30 days' notice in writing,
mailed to the Rights Agent or successor Rights Agent, as the case may be, and to
each transfer  agent for the Common Shares or Preferred  Shares by registered or
certified  mail,  and to the holders of the Right  Certificates  by  first-class
mail. If the Rights Agent shall resign or be removed or shall  otherwise  become
incapable of acting,  the Company shall appoint a successor to the Rights Agent.
If the Company  shall fail to make such  appointment  within a period of 30 days
after giving  notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Right  Certificate (who shall,  with such notice,  submit 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 either (a) a  corporation  business
trust or limited  liability  company organized and doing business under the laws
of the  United  States  or of any  other  state of the  United



                                       26
<PAGE>


States which is authorized under such laws to exercise  corporate trust or stock
transfer powers and is subject to supervision or examination by federal or state
authority  and  which  has at the  time of its  appointment  as  Rights  Agent a
combined capital and surplus of at least $50 million or (b) a direct or indirect
wholly owned  subsidiary of such an entity or its  wholly-owning  parent.  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 for the  Common  Shares or
Preferred Shares, and mail a notice thereof in writing to the registered holders
of the Right  Certificates.  Failure  to give any  notice  provided  for in this
Section 21,  however,  or any defect  therein,  shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be.

SECTION  22.  ISSUANCE  OF NEW RIGHT  CERTIFICATES.  Notwithstanding  any of the
provisions of this Agreement or of the Rights to the contrary,  the Company may,
at its option,  issue new Right  Certificates  evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Right Certificates made in accordance with the
provisions of this  Agreement.  In addition,  in connection with the issuance or
sale of Common Shares following the  Distribution  Date and prior to the earlier
of the Redemption Date and the Final Expiration Date, the Company (a) shall with
respect to Common  Shares so issued or sold  pursuant  to the  exercise of stock
options or under any employee  plan or  arrangement  in  existence  prior to the
Distribution  Date, or upon the exercise,  conversion or exchange of securities,
notes  or  debentures  issued  by the  Company  and in  existence  prior  to the
Distribution  Date,  and (b) may,  in any other  case,  if deemed  necessary  or
appropriate by the Board of Directors of the Company,  issue Right  Certificates
representing  the appropriate  number of Rights in connection with such issuance
or sale; provided, however, that (i) the Company shall not be obligated to issue
any such Right  Certificates  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 Right Certificate shall be issued
if, and to the extent that,  appropriate  adjustment  shall  otherwise have been
made in lieu of the issuance thereof.

SECTION 23. REDEMPTION.

     (a) The Rights may be redeemed by action of the Board of Directors pursuant
to Section 23(b) hereof and shall not be redeemed in any other manner.

     (b)

          (i) The Board of Directors  of the Company may, at its option,  at any
     time prior to the earlier of such time as any Person  becoming an Acquiring
     Person or the Final  Expiration  Date,  redeem all but not less than all of
     the then outstanding Rights at a redemption



                                       27
<PAGE>



     price of $0.01 per  Right,  appropriately  adjusted  to  reflect  any stock
     split,  stock  dividend  or similar  transaction  occurring  after the date
     hereof  (such  redemption  price  being  hereinafter  referred  to  as  the
     "Redemption Price"), and the Company may, at its option, pay the Redemption
     Price in Common Shares (based on the "current  per-share  market price," as
     such term is defined in Section 11(d)  hereof,  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
     Board of Directors  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.  Notwithstanding anything contained in this Agreement to the
     contrary, the Rights shall not be exercisable pursuant to Section 11(a)(ii)
     hereof prior to the  expiration or  termination  of the Company's  right of
     redemption under this Section 23(b)(i).

          (ii) In  addition,  the Board of  Directors of the Company may, at its
     option, at any time after the time a Person becomes an Acquiring Person and
     the expiration of any period during which the holder of Rights may exercise
     the rights under Section  11(a)(ii) hereof but prior to any event described
     in clause  (x),  (y) or (z) of the first  sentence  of  Section  13 hereof,
     redeem  all but not less  than all of the then  outstanding  Rights  at the
     Redemption  Price (x) in connection with any merger,  consolidation or sale
     or  other  transfer  (in  one   transaction  or  in  a  series  of  related
     transactions)  of assets or earning  power  aggregating  50% or more of the
     assets or earning  power of the  Company and its  subsidiaries  (taken as a
     whole) in which all  holders  of Common  Shares are  treated  alike and not
     involving  (other than as a holder of Common  Shares being treated like all
     other such holders) an Interested  Shareholder  or a Transaction  Person or
     (y)(A) if and for so long as the  Acquiring  Person is not  thereafter  the
     Beneficial Owner of 15% or more of the then outstanding  Common Shares, and
     (B) at the time of redemption no other Persons are Acquiring Persons.

     (c)  Immediately  upon the action of the Board of  Directors of the Company
ordering the  redemption of the Rights  pursuant to Section  23(b)  hereof,  and
without any further  action and  without any notice,  the right to exercise  the
Rights will  terminate  and the only right  thereafter  of the holders of Rights
shall be to receive the Redemption Price. The Company shall promptly give public
notice of any such redemption;  provided,  however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within  10 days  after  such  action  of the  Board of  Directors  ordering  the
redemption of the Rights  pursuant to Section  23(b)  hereof,  the Company shall
mail a notice of redemption to all the holders of the then outstanding Rights at
their last  addresses as they appear upon the registry books of the Rights Agent
or, prior to the Distribution  Date, on the registry books of the transfer agent
for the Common Shares,  provided,  however,  that failure to give, or any defect
in, any such notice shall not affect the validity of such redemption. Any notice
which is mailed in the manner herein provided shall be deemed given,  whether or
not the holder  receives the notice.  Each such notice of redemption  will state
the method by which the payment of the  Redemption  Price will be made.  Neither
the Company  nor any of its  Affiliates  or  Associates  may redeem,  acquire or
purchase  for  value  any  Rights  at any time in any  manner  other  than  that
specifically  set forth in this  Section 23 or in  Section 24 hereof,  and other
than in connection with the purchase of Common Shares prior to the  Distribution
Date.



                                       28
<PAGE>


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

SECTION 24. EXCHANGE.

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

     (b)  Immediately  upon the action of the Board of  Directors of the Company
ordering the exchange of any Rights pursuant to Section 24(a) hereof and without
any further  action and without  any notice,  the right to exercise  such Rights
shall  terminate and the only right  thereafter of a holder of such Rights shall
be to receive  that number of Common  Shares  equal to the number of such Rights
held by such holder multiplied by the Exchange Ratio. The Company shall promptly
give public notice of any such exchange;  provided, however, that the failure to
give,  or any defect in,  such  notice  shall not  affect the  validity  of such
exchange.  The Company  promptly shall mail a notice of any such exchange to all
of the  holders of such Rights at their last  addresses  as they appear upon the
registry books of the Rights Agent; provided, however, that the failure to give,
or any defect in, such notice  shall not affect the  validity of such  exchange.
Any notice which is mailed in the manner herein  provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will
state the method by which the  exchange of the Common  Shares for Rights will be
effected and, in the event of any partial  exchange,  the number of Rights which
will be exchanged.  Any partial exchange shall be effected pro rata based on the
number of Rights  (other  than Rights  which have  become  void  pursuant to the
provisions of Section 11(a)(ii) hereof) held by each holder of Rights.

     (c) In lieu of issuing  Common  Shares in  accordance  with  Section  24(a)
hereof,  the Company may, if a majority of the Board of Directors then in office
determines  that such action is necessary or appropriate and not contrary to the
interests of the holders of Rights,  elect to (and,  in the event that there are
not sufficient  treasury  shares and  authorized  but unissued  Common Shares to
permit any exchange of the Rights in accordance  with Section 24(a) hereof,  the
Company  shall) take all such action as may be necessary to authorize,  issue or
pay, upon the



                                       29
<PAGE>


exchange of the Rights,  cash  (including  by way of a reduction of the Purchase
Price),  property,  Common Shares,  other securities or any combination  thereof
having  an  aggregate  value  equal to the  value  of the  Common  Shares  which
otherwise  would have been  issuable  pursuant to Section  24(a)  hereof,  which
aggregate  value  shall be  determined  by a  nationally  recognized  investment
banking firm  selected by a majority of the Board of  Directors  then in office.
For purposes of the preceding sentence,  the value of the Common Shares shall be
determined  pursuant to Section  11(d)  hereof.  Any  election  pursuant to this
Section  24(c) by the Board of Directors  must be made within 60 days  following
the date on which the event  described  in Section  11(a)(ii)  hereof shall have
occurred.  Following the occurrence on the event described in Section  11(a)(ii)
hereof,  a majority  of the Board of  Directors  then in office may  suspend the
exercisability of the Rights for a period of up to 60 days following the date on
which the event described in Section 11(a)(ii) hereof shall have occurred to the
extent that such directors have not determined  whether to exercise their rights
of election under this Section 24(c). In the event of any such  suspension,  the
Company shall issue a public announcement stating that the exercisability of the
Rights has been temporarily suspended.

     (d) The Company  shall not be required to issue  fractions of Common Shares
or to distribute  certificates which evidence  fractional Common Shares. In lieu
of such  fractional  Common  Shares,  the  Company  shall pay to the  registered
holders of the Right  Certificates  with regard to which such fractional  Common
Shares would  otherwise be issuable an amount in cash equal to the same fraction
of the current  market value of a whole Common  Share.  For the purposes of this
Section  24(d),  the current  market  value of a whole Common Share shall be the
closing price of a Common Share (as determined  pursuant to the second  sentence
of Section  11(d)(i)  hereof) for the Trading Day immediately  after the date of
the first public  announcement by the Company that an exchange is to be effected
pursuant to this Section 24.

     (e) 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 exchange of the Rights or to distribute  certificates
which  evidence  fractional  Preferred  Shares (other than  fractions  which are
integral  multiples of one  one-hundredth  of a Preferred  Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may, at the  election of the  Company,  be  evidenced  by  depositary  receipts;
provided,  however,  that holders of such depositary  receipts shall have all of
the designations and the powers, preferences and rights, and the qualifications,
limitations and restrictions to which they are entitled as beneficial  owners of
the  Preferred  Shares  represented  by  such  depositary  receipts.  In lieu of
fractional Preferred Shares that are not integral multiples of one one-hundredth
of a Preferred Share,  the Company shall pay to the registered  holders of Right
Certificates  at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current  market value of one Preferred
Share.  For the purposes of this Section  24(e),  the current  market value of a
Preferred  Share shall be one hundred  (100) times the closing price of a Common
Share (as determined pursuant to the second sentence of Section 11(d)(i) hereof)
for the Trading Day immediately after the date of the first public  announcement
by the Company that an exchange is to be effected pursuant to this Section 24.

SECTION 25. NOTICE OF CERTAIN EVENTS.

     (a) In case the Company  shall  propose (i) to pay any dividend  payable in
stock of any class to the holders of its  Preferred  Shares or to make any other
distribution  to the  holders  of its  Preferred  Shares  (other  than a regular
quarterly cash dividend),  (ii) to offer to the holders of its Preferred  Shares
rights or warrants to  subscribe  for or to purchase  any  additional  Preferred
Shares  or  shares  of stock of any  class or any  other  securities,  rights or
options,  (iii) to effect any  reclassification  of its Preferred  Shares (other
than a reclassification  involving only the subdivision of outstanding Preferred
Shares),  (iv) to effect any  consolidation or merger into or with, or to effect
any sale or other  transfer  (or to permit  one or more of its  Subsidiaries  to
effect any sale or other transfer), in one or more transactions,  of 50% or more
of the assets or earning power of the Company and its  Subsidiaries  (taken as a
whole),  to any other  Person,  (v) to effect the  liquidation,  dissolution  or
winding up of the Company,  or (vi) to declare or pay any dividend on the Common
Shares  payable  in Common  Shares or to effect a  subdivision,  combination  or
consolidation  of the Common Shares (by  reclassification  or otherwise  than by
payment of dividends in Common  Shares),  then,  in each such case,  the Company
shall give to each holder of a Right Certificate,  in accordance with Section 26
hereof,  a notice of such proposed  action,  which shall specify the record date
for the purpose of such stock  dividend,  or distribution of rights or warrants,
or the  date  on  which  such  reclassification,  consolidation,  merger,  sale,
transfer, liquidation,  dissolution, or winding up is to take place and the date
of  participation  therein  by the  holders  of the  Common  Shares  and/or  the
Preferred  Shares,  if any such date is to be fixed, and such notice shall be so
given in the case of any action  covered by clause (i) or (ii) above at least 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
10 days prior to the date of the taking of such  proposed  action or the date of
participation  therein by the holders of the Common  Shares and/or the Preferred
Shares, whichever shall be the earlier.

     (b) In case the event set forth in Section  11(a)(ii)  hereof  shall occur,
then the Company shall as soon as practicable  thereafter give to each holder of
a Right  Certificate,  in  accordance  with  Section 26 hereof,  a notice of the
occurrence  of such  event,  which  notice  shall  describe  the  event  and the
consequences of the event to holders of Rights under Section 11(a)(ii) hereof.

SECTION 26. NOTICES. Notices or demands authorized by this Agreement to be given

SECTION 27.  SUPPLEMENTS AND  AMENDMENTS.  Prior to the  Distribution  Date, the
Company and the Rights Agent  shall,  if the Company so directs,  supplement  or
amend any provision of this Agreement without the approval of any holders of the
Rights.  From and after the Distribution  Date, the Company and the Rights Agent
shall,  if the Company so  directs,  from time to time  supplement  or amend any
provision  of this  Agreement  without  the  approval  of any  holders  of Right
Certificates in order to (i) cure any ambiguity,  (ii) correct or supplement any
provision contained herein which may be defective or inconsistent with any other
provisions  herein,  or (iii)  change any other  provisions  with respect to the
Rights which the Company may deem  necessary or  desirable;  provided,  however,
that no such supplement or amendment shall be made which would adversely  affect

Person or its Affiliates or  Associates).  Any  supplement or amendment  adopted
during any period after any Person has become an  Acquiring  Person but prior to
the  Distribution  Date shall  become null and void unless  such  supplement  or
amendment could have been adopted by the Company from and after the Distribution
Date. Any such supplement or amendment shall be evidenced by a writing signed by
the  Company  and the Rights  Agent.  Upon  delivery  of a  certificate  from an
appropriate  officer of the Company which states that the proposed supplement or
amendment is in  compliance  with the terms of this Section 27, the Rights Agent
shall execute such  supplement  or amendment  unless the Rights Agent shall have
determined  in good faith that such  supplement  or  amendment  would  adversely
affect its interest under this Agreement.  Prior to the  Distribution  Date, the
interests of the holders of Rights shall be deemed coincident with the interests

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                         (EXHIBIT A TO RIGHTS AGREEMENT)

     The undersigned, Bing Yeh and Jeffrey L. Garon, hereby certify that:

     A. They are the duly  elected  and  acting  President  and Chief  Executive
Officer,  and Secretary,  respectively  of Silicon Storage  Technology,  Inc., a
California corporation (the "Company").

     B. Pursuant to authority  conferred by the Company's  Restated  Articles of
Incorporation,  the board of directors of the Company (the "Board of Directors")
has duly adopted the following resolution:

          RESOLVED,  that pursuant to the authority granted to and vested in the
     Board of Directors of the Company in accordance  with the provisions of its
     Restated Articles of Incorporation, the Board of Directors hereby creates a
     series of  Preferred  Stock,  without par value,  of the Company and hereby
     states  the  designation  and  number of  shares,  and  fixes the  relative
     designations   and   the   powers,   preferences   and   rights,   and  the
     qualifications,  limitations and  restrictions  thereof (in addition to the
     provisions set forth in the Articles of Incorporation of the Company, which
     are  applicable  to the  Preferred  Stock of all  classes and  series),  as
     follows:

Series A Junior Participating Preferred Stock:

     Section 1.  Designation and Amount.  Four Hundred Fifty Thousand  (450,000)
shares of Preferred Stock,  without par value,  are designated  "Series A Junior
Participating Preferred Stock" with the designations and the powers, preferences
and rights,  and the  qualifications,  limitations  and  restrictions  specified
herein (the "Junior Preferred Stock"). 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 Junior  Preferred  Stock to a number  less
than one  one-hundredth of 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



                                      A-1
<PAGE>


the conversion of any outstanding  securities issued by the Company  convertible
into Junior Preferred Stock.

     Section 2. Dividends and Distributions.

     (A)  Subject  to the  rights of the  holders of any shares of any series of
Preferred  Stock (or any similar stock) ranking prior and superior to the Junior
Preferred  Stock with  respect  to  dividends,  the  holders of shares of Junior
Preferred Stock, in preference to the holders of Common Stock, without par value
(the "Common Stock"),  of the Company,  and of any other junior stock,  shall be
entitled to receive,  when,  as and if declared by the Board of Directors out of
funds legally available for the purpose,  quarterly dividends payable in cash on
the first day of April,  July,  October and January in each year (each such date
being referred to herein as a "Quarterly Dividend Payment Date"),  commencing on
the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Junior  Preferred  Stock, in an amount per share (rounded
to the  nearest  cent)  equal to the  greater of (a) $l.00 or (b) subject to the
provision  for  adjustment  hereinafter  set forth,  100 times the aggregate per
share amount of all cash dividends, and 100 times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions, other than a
dividend  payable in shares of Common Stock or a subdivision of the  outstanding
shares of Common  Stock (by  reclassification  or  otherwise),  declared  on the
Common Stock since the immediately preceding Quarterly Dividend Payment Date or,
with  respect to the first  Quarterly  Dividend  Payment  Date,  since the first
issuance of any share or fraction of a share of Junior  Preferred  Stock. In the
event the Company  shall at any time  declare or pay any  dividend on the Common
Stock payable in shares of Common Stock,  or effect a subdivision or combination
or consolidation of the outstanding shares of Common Stock (by  reclassification
or  otherwise  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 Junior  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  Company  shall  declare a dividend or  distribution  on the Junior
Preferred Stock as provided in paragraph (A) of this Section  immediately  after
it  declares a  dividend  or  distribution  on the Common  Stock  (other  than a
dividend  payable  in shares of Common  Stock);  provided,  that in the event no
dividend or distribution shall have been declared on the Common Stock during the
period  between any  Quarterly  Dividend  Payment  Date and the next  subsequent
Quarterly  Dividend  Payment  Date,  a dividend of $1.00 per share on the Junior
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  Junior  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



                                      A-2
<PAGE>


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 Junior 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 Junior  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 Junior  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.

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

     (A) Subject to the provision for  adjustment  hereinafter  set forth,  each
share of Junior Preferred Stock shall entitle the holder thereof to 100 votes on
all matters submitted to a vote of the stockholders of the Company. In the event
the Company  shall at any time  declare or pay any  dividend on the Common Stock
payable in shares of Common Stock,  or effect a subdivision  or  combination  or
consolidation of the outstanding shares of Common Stock (by  reclassification or
otherwise  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 Junior  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 any other  Certificate  of
Designation  creating a series of Preferred  Stock or any similar  stock,  or by
law, the holders of shares of Junior  Preferred  Stock and the holders of shares
of Common Stock and any other capital stock of the Company having general voting
rights  shall vote  together as one class on all matters  submitted to a vote of
stockholders of the Company.

     (C) Except as set forth herein, or as otherwise provided by law, holders of
Junior  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.

     Section 4. Certain Restrictions.

     (A)  Whenever  quarterly  dividends  or other  dividends  or  distributions
payable on the Junior  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 Junior Preferred Stock outstanding shall have been
paid in full, the Company shall not:



                                      A-3
<PAGE>


          (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 Junior 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 Junior  Preferred  Stock,
     except  dividends paid ratably on the Junior  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 Junior Preferred Stock, provided that the
     Company may at any time redeem, purchase or otherwise acquire shares of any
     such  junior  stock in  exchange  for  shares of any  stock of the  Company
     ranking junior (either as to dividends or upon dissolution,  liquidation or
     winding up) to the Junior Preferred Stock; or

          (iv) redeem or purchase or  otherwise  acquire for  consideration  any
     shares of Junior  Preferred  Stock,  or any  shares of stock  ranking  on a
     parity (either as to dividends or upon liquidation,  dissolution or winding
     up) with the Junior 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 Company shall not permit any  subsidiary of the Company to purchase
or otherwise acquire for consideration any shares of stock of the Company unless
the Company 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  Junior  Preferred  Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and cancelled  promptly after the acquisition  thereof.  All such shares
shall upon their cancellation become authorized but unissued shares of Preferred
Stock and may be reissued as part of a new series of Preferred  Stock subject to
the conditions and  restrictions  on issuance set forth herein,  in the Restated
Articles of Incorporation, or in any other Certificate of Determination creating
a series of Preferred  Stock or any similar  stock or as  otherwise  required by
law.

     Section 6.  Liquidation,  Dissolution or Winding Up. Upon any  liquidation,
dissolution or winding up of the Company,  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 Junior  Preferred  Stock unless,
prior  thereto,  the  holders  of shares of Junior  Preferred  Stock  shall have
received  $100 per share,  plus an amount equal to accrued and unpaid  dividends
and distributions thereon, whether or not declared, to the date of such payment,
provided that the holders of shares of Junior  Preferred Stock shall be entitled
to  receive  an  aggregate  amount  per



                                      A-4
<PAGE>


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
Junior  Preferred  Stock,  except  distributions  made  ratably  on  the  Junior
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 Company shall at any time declare or
pay any  dividend  on the Common  Stock  payable in shares of Common  Stock,  or
effect a subdivision or combination or consolidation  of the outstanding  shares
of Common Stock (by  reclassification or otherwise 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
Junior 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 were outstanding  immediately
prior to such event.

     Section 7. Consolidation, Merger, Etc. In case the Company shall enter into
any consolidation,  merger, combination or other transaction in which the shares
of Common Stock are  exchanged  for or changed  into other stock or  securities,
cash  and/or  any other  property,  then in any such  case each  share of Junior
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  Company
shall at any time  declare or pay any  dividend on the Common  Stock  payable in
shares of Common Stock, or effect a subdivision or combination or  consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise 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
Junior  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 Junior Preferred Stock shall not be
redeemable.

     Section 9. Rank. The Junior Preferred Stock shall rank, with respect to the
payment of dividends and the distribution of assets, junior to all series of any
other class of the Company's Preferred Stock.

     Section  10.  Amendment.  The  Restated  Articles of  Incorporation  of the
Company  shall not be amended  in any manner  which  would  materially  alter or
change the powers,  preferences or special rights of the Junior  Preferred Stock
so as to affect them adversely without



                                      A-5
<PAGE>


the  affirmative  vote of the holders of at least  two-thirds of the outstanding
shares of Junior Preferred Stock, voting together as a single class.



                                      A-6
<PAGE>


     C. The  authorized  number of shares of  Preferred  Stock of the Company is
Seven Million  (7,000,000) shares and the number of shares  constituting  Junior
Preferred Stock,  none of which has been issued,  is Four Hundred Fifty Thousand
(450,000).

date evidencing  Rights entitling the holder to purchase a like aggregate number
of Preferred  Shares as the Rights  evidenced by the Right  Certificate or Right
Certificates  surrendered  shall have entitled such holder to purchase.  If this
Right  Certificate  shall be exercised in part,  the holder shall be entitled to
receive upon surrender  hereof another Right  Certificate or Right  Certificates
for the number of whole Rights not exercised.

     Subject to the provisions of the Rights Agreement,  the Rights evidenced by
this  Certificate  (i) may be redeemed by the Company at a  redemption  price of
$.01 per Right or (ii) may be  exchanged  in whole or in part for  shares of the
Company's Common Stock,  without par value or, upon  circumstances  set forth in
the  Rights  Agreement,  cash,  property  or other  securities  of the  Company,
including fractions of a share of Preferred Stock.

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

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

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

                           (Exhibit C to Rights Plan)


     On May 4, 1999, the Board of Directors of Silicon Storage Technology,  Inc.
(the  "Company")  declared a dividend of one preferred  share  purchase right (a
"Right")  for each  outstanding  share of common  stock,  without par value (the
"Common Shares"),  of the Company.  The dividend is effective as of May 27, 1999
(the "Record Date") with respect to the shareholders of record on that date. The
Rights will also attach to new Common Shares issued after the Record Date.  Each
Right  entitles  the  registered   holder  to  purchase  from  the  Company  one
one-hundredth  of a share  of  Series A Junior  Participating  Preferred  Stock,
without par value (the "Preferred Shares"),  of the Company at a price of $40.00
per one  one-hundredth of a Preferred Share (the "Purchase  Price"),  subject to
adjustment.  Each Preferred  Share is designed to be the economic  equivalent of
100 Common Shares.  The  description  and terms of the Rights are set forth in a
Rights Agreement dated as of May 4, 1999 (the "Rights  Agreement"),  between the
Company and American Stock Transfer & Trust Company (the "Rights Agent").

DETACHMENT AND TRANSFER OF RIGHTS

     Initially,   the  Rights  will  be  evidenced  by  the  stock  certificates
representing Common Shares then outstanding,  and no separate Right Certificates
will be  distributed.  Until the  earlier to occur of (i) a public  announcement
that a person  or group of  affiliated  or  associated  persons,  has  become an
"Acquiring  Person" (as such term is defined in the Rights Agreement) or (ii) 10
business  days (or such later  date as the Board may  determine)  following  the
commencement  of, or  announcement  of an  intention  to make, a tender offer or
exchange  offer which would result in the  beneficial  ownership by an Acquiring
Person of 15% or more of the  outstanding  Common  Shares  (the  earlier of such
dates being called the "Distribution Date"), the Rights will be evidenced,  with
respect to any of the Common  Share  certificates  outstanding  as of the Record
Date, by such Common Share certificate.  In general,  an "Acquiring Person" is a
person,  the  affiliates  or associates  of such person,  or a group,  which has
acquired  beneficial  ownership of 15% or more of the outstanding Common Shares,
provided that certain "Excluded Shareholders" as defined in the Rights Agreement
may have greater beneficial ownership without becoming an "Acquiring Person."

     The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights),  the Rights will be  transferable  with
and only  with the  Common  Shares.  Until  the  Distribution  Date (or  earlier
redemption or expiration of the Rights),  new Common Share  certificates  issued
after the Record  Date upon  transfer  or new  issuance  of Common  Shares  will
contain a notation  incorporating  the Rights Agreement by reference.  Until the
Distribution  Date (or  earlier  redemption  or  expiration  of the  Rights) the
surrender or transfer of any  certificates  for Common Shares  outstanding as of
the Record Date,  even without such notation or a copy of this Summary of Rights
being  attached  thereto,  will  also  constitute  the  transfer  of the



                                       C-1
<PAGE>


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

EXERCISABILITY OF RIGHTS

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on May 3, 2009 (the "Final Expiration Date"), unless the Final Expiration
Date is extended or unless the Rights are earlier  redeemed or  exchanged by the
Company, in each case as described below. Until a Right is exercised, the holder
thereof,  as  such,  will  have  no  rights  as a  shareholder  of the  Company,
including, without limitation, the right to vote or to receive dividends.

     The Purchase  Price  payable,  and the number of Preferred  Shares or other
securities  or property  issuable or  payable,  upon  exercise of the Rights are
subject  to  adjustment  from time to time to  prevent  dilution.  The number of
outstanding  Rights and the number of one  one-hundredths  of a Preferred  Share
issuable upon exercise of each Right are also subject to adjustment in the event
of a stock split of the Common  Shares or a stock  dividend on the Common Shares
payable in Common Shares, or subdivisions, consolidations or combinations of the
Common Shares occurring,  in any such case, prior to the Distribution Date. With
certain  exceptions,  no adjustment in the Purchase Price will be required until
cumulative  adjustments  require an  adjustment  of at least 1% in such Purchase
Price. No fractional Preferred Shares will be issued (other than fractions which
are integral  multiples of one one-hundredth of a Preferred Share, which may, at
the election of the Company,  be evidenced by  depositary  receipts) and in lieu
thereof,  an  adjustment  in cash will be made based on the market  price of the
Preferred Shares on the last trading day prior to the date of exercise.

TERMS OF PREFERRED SHARES

     Preferred  Shares  purchasable  upon  exercise  of the  Rights  will not be
redeemable.  Each  Preferred  Share will be entitled  to a minimum  preferential
quarterly  dividend payment of $l per share but will be entitled to an aggregate
dividend of 100 times the dividend  declared per Common  Share.  In the event of
liquidation,  the holders of the Preferred  Shares will be entitled to a minimum
preferential  liquidation  payment of $100 per share but will be  entitled to an
aggregate payment of 100 times the payment made per Common Share. Each Preferred
Share will have 100 votes,  voting together with the Common Shares.  Finally, in
the event of any merger,  consolidation  or other  transaction  in which  Common
Shares are exchanged, each Preferred Share will be entitled to receive 100 times
the amount  received per Common  Share.  These rights are protected by customary
anti-dilution  provisions.  Because  of  the  nature  of the  Preferred  Shares'
dividend,  liquidation  and voting  rights,  the value of the one  one-hundredth
interest in a Preferred  Share  purchasable  upon  exercise of each Right should
approximate  the value of one Common  Share.  The  Preferred  Shares  would rank
junior to any other series of the Company's preferred stock.

TRIGGER OF FLIP-IN AND FLIP-OVER RIGHTS

     In the event that any person or group of affiliated  or associated  persons
becomes an Acquiring Person,  proper provision shall be made so that each holder
of a Right, other than Rights  beneficially owned by the Acquiring Person or any
affiliate or associate  thereof (which will thereafter be void), will thereafter
have the right to receive upon  exercise  that number of Common  Shares having a
market  value of two times the  exercise  price of the  Right.  This  right will
commence  on the  date of  public  announcement  that a  person  has  become  an
Acquiring Person (or the effective date of a registration  statement relating to
distribution  of the rights,  if later) and terminate 60 days later  (subject to
adjustment in the event exercise of the rights is enjoined).

     In the event that the  Company is  acquired  in a merger or other  business
combination  transaction  or 50% or more of its  consolidated  assets or earning
power are sold to an Acquiring  Person,  its affiliates or associates or certain
other persons in which such persons have an interest,  proper  provision will be
made so that  each  such  holder of a Right  will  thereafter  have the right to
receive,  upon the exercise  thereof at the then current  exercise  price of the
Right,  that number of shares of common stock of the acquiring  company which at
the time of such  transaction will have a market value of two times the exercise
price of the Right.

REDEMPTION AND EXCHANGE OF RIGHTS

     At any time prior to the  earliest  of (i) the close of business on the day
of the first public  announcement  that a person has become an Acquiring Person,
or (ii) the Final  Expiration  Date,  the Board of  Directors of the Company may
redeem the Rights in whole,  but not in part,  at a price of $.01 per Right (the
"Redemption  Price").  In  general,  the  redemption  of the  Rights may be made
effective  at such  time on such  basis  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.

     At any time after any Person  becomes an Acquiring  Person and prior to the
acquisition  by such  person or group of 50% or more of the  outstanding  Common
Shares,  the Board of Directors  of the Company may  exchange the Rights  (other
than Rights owned by such person or group which will have become void), in whole
or in part, at an exchange  ratio of one Common Share,  or, under  circumstances
set forth in the Rights  Agreement,  cash,  property or other  securities of the
Company,  including  fractions of a Preferred Share (or of a share of a class or
series of the Company's  preferred stock having equivalent  designations and the
powers,  preferences  and  rights,  and  the  qualifications,   limitations  and
restrictions), per Right (with value equal to such Common Shares).

AMENDMENT OF RIGHTS

     The terms of the Rights  generally may be amended by the Board of Directors
of the Company  without  the  consent of the holders of the Rights,  except that
from and after such time



                                      C-3
<PAGE>


as the  Rights  are  distributed  no such  amendment  may  adversely  affect the
interests of the holders of the Rights  (excluding the interest of any Acquiring
Person).
