                                RIGHTS AGREEMENT

THIS RIGHTS AGREEMENT ("Agreement"), dated as of October 5, 2001, between KOSAN
BIOSCIENCES Incorporated, a Delaware corporation (the "Company"), and MELLON
INVESTOR SERVICES LLC, a New Jersey limited liability 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
October 29, 2001 (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:

SECTION 1.        CERTAIN DEFINITIONS. For purposes of this Agreement, the
following terms have the meanings indicated:

         (a)      "ACQUIRING PERSON" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates and Associates
(as such terms are hereinafter defined) of such Person, shall be the Beneficial
Owner (as such term is hereinafter defined) of 20% 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 or (iv) any entity holding
Common Shares for or pursuant to the terms of any such employee benefit or
compensation plan of the Company or any Subsidiary of the Company 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 20% or more of the Common Shares then outstanding;
provided, however, that if a Person shall become the Beneficial Owner of 20% 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 20% of the Common Shares then outstanding, then
such Person shall be deemed to be an "Acquiring Person," or (y) as the result of
the acquisition of Common Shares directly from the Company, provided however
that if a Person shall become the Beneficial Owner of 20% or more of the Common
Shares then outstanding by reason of share purchases directly from the Company
and shall, after that date, become Beneficial Owner of any additional Common
Shares without the prior written consent of the Company and shall then


                                       1.


Beneficially Own more than 20% of the Common Shares then outstanding, then such
Person shall be deemed to be an "Acquiring Person" or (z) 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 the Board of Directors),
following receipt of written notice from the Company of such event, of
Beneficial Ownership of a sufficient number of Common Shares so that such Person
would no longer be an Acquiring Person, as defined pursuant to the foregoing
provisions of this paragraph (a), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement; provided, however, that
if such Person shall again become the Beneficial Owner of 20% or more of the
Common Shares then outstanding, such Person shall be deemed an "Acquiring
Person," subject to the exceptions set forth in this Section 1(a).

         (b)      "AFFILIATE" and "ASSOCIATE" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as in
effect on the date of this Agreement; provided, however, that the limited
partners of a limited partnership shall not be deemed to be Associates of such
limited partnership solely by virtue of their limited partnership interests.

         (c)      A Person shall be deemed the "BENEFICIAL OWNER" of and shall
be deemed to "beneficially own" any securities:

Associates is deemed to beneficially own, within the meaning of Rule 13d-3 of
the General Rules and Regulations under the Exchange Act as in effect on the
date of this Rights Agreement;

                  (ii) which such Person or any of such Person's Affiliates or
Associates has (A) the right to acquire (whether such right is exercisable
immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding (other than customary agreements with and between
underwriters and selling group members with respect to a bona fide public
offering of securities and other than agreements between the Company and any
corporate partner pursuant to which the right to purchase shares is conditioned
upon the achievement of research or development milestones), or upon the
exercise of conversion rights, exchange rights, rights (other than these
Rights), warrants or options, or otherwise; provided, however, that a Person
shall not be deemed the Beneficial Owner of, or to beneficially own, securities
tendered pursuant to a tender or exchange offer made by or on behalf of such
Person or any of such Person's Affiliates or Associates until such tendered
securities are accepted for purchase or exchange; or (B) the right to vote
pursuant to any agreement, arrangement or understanding; provided, however, that
a Person shall not be deemed the Beneficial Owner of, or to beneficially own,
any security if the agreement, arrangement or understanding to vote such
security (1) arises solely from a revocable proxy or consent given to such
Person in response to a public proxy or consent solicitation made pursuant to,
and in accordance with, the applicable rules and regulations promulgated under
the Exchange Act and (2) is not also then reportable on Schedule 13D under the
Exchange Act (or any comparable or successor report); or

                  (iii) which are beneficially owned, directly or indirectly, by
any other Person with which such Person or any of such Person's Affiliates or
Associates has any agreement,

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 understanding for purposes of this Section 1(c)(iii) shall not be
deemed to include actions, including any agreement, arrangement or
understanding, or statements by any member of the Company's Board of Directors
on the date of this Agreement, any subsequent directors of the Company (the
"Successor Directors") who have been nominated by a majority of directors who
are directors as of the date of this Agreement or who are Successor Directors,
or by any Person of whom such a director is an Affiliate or Associate, provided,
however that this exception shall not apply to a particular Person or Persons if
and to the extent that such Person or Persons, after the date of this Agreement,
acquires Beneficial Ownership of more than an additional 5% of the then
outstanding Common Shares of the Company unless (A) the shares are acquired
directly from the Company or as part of an employee benefit or compensation plan
of the Company or a subsidiary of the Company or (B) the Person establishes to
the satisfaction of the directors of the Company that it is acting on its own
behalf and not in concert with any other Person and will not, upon completion of
any purchases, be the Beneficial Owner of 20% or more of the outstanding Common
Shares.

                  Notwithstanding anything in this definition of Beneficial
Ownership to the contrary, the phrase, "then outstanding," when used with

                  date as may be determined by action of the Board of Directors

                  Company or any entity holding Common Shares for or pursuant to
                  the terms of any such plan) of, or of the first public
                  announcement of the intention of any Person (other than the
                  Company, any Subsidiary of the Company, any employee benefit
                  plan of the Company or of any Subsidiary of the Company or any
                  entity holding Common Shares for or pursuant to the terms of
                  any such plan) to commence, a tender or exchange offer (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 promptly notify the Rights Agent thereof, and
                  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 and provided with a shareholder list
                  and all other relevant information, 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 and
                  after 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.


                                       5.


         (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 Kosan
         Biosciences Incorporated (the "Company") and Mellon Investor Services
         LLC as Rights Agent (the "Rights Agent"), dated as of October 5, 2001,
         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 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 (or, if earlier, the
                  earlier of the Redemption Date or the Final Expiration 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 (but that do not affect the rights, duties or
                  responsibilities of the Rights Agent) and as are not
                  inconsistent with the provisions of this Agreement, or as may
                  be required to comply with any applicable law or with any rule
                  or regulation made pursuant thereto or with any rule or
                  regulation of any stock exchange or quotation system


                                       6.


                  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
                  Purchase Price (as defined in Section 7(b)), 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 the second paragraph of 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 and to the
                  extent the Rights Agent has been notified thereof) 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.

                  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 and receipt by the Rights
                  Agent of all necessary information, 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


                                       7.


                  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 properly
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 or the Rights Agent 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 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. The Rights
Agent shall have no duty or obligation to take any action under any Section of
this Agreement that requires the payment by a Rights holder of applicable taxes
and governmental charges unless and until the Rights Agent is reasonably
satisfied that all such taxes and/or charges have been paid.

                  Upon receipt by the Company and the Rights Agent of evidence
                  reasonably satisfactory to them of the loss, theft,
                  destruction or mutilation of a Right Certificate, and, in case
                  of loss, theft or destruction, of indemnity or security
                  satisfactory to them, and, at the Company's or Rights Agent'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.


                                       8.


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 October 29, 2011 (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 for each one one-hundredth of a Preferred
                  Share pursuant to the exercise of a Right shall initially be
                  $70.00 (the "Purchase Price") 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 tax or
                  charge 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 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


                                       9.


                  distribution by the Rights Agent, if and when necessary to
                  comply with this Agreement.

                  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 (other
                  than a partial exercise of rights pursuant to Section
                  11(a)(ii) as described in Section 7(c) hereof), 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 Sections 6
                  and 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) duly
                  and properly 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, (ii)
                  tendered the Purchase Price (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) to the
                  Company in the manner set forth in Section 7(c) and (iii)
                  provided such additional evidence of the identity of the
                  Beneficial Owner (or former Beneficial Owner) or Affiliates or
                  Associates thereof as the Company or the Rights Agent shall
                  reasonably request.

SECTION 8.        CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES. All Right
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in 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 Right Certificate purchased or acquired by the
Company otherwise than upon the exercise


                                      10.


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 taxes and governmental 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 tax or charge that 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 or charge shall have been paid (any such tax or
                  charge being payable by the holder of such Right Certificate
                  at the time of surrender) or until it has been established to
                  the Company's reasonable satisfaction that no such tax or
                  charge 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 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


                                      11.


                  (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.

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 taxes and
charges) 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


                                      12.


                           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.

                  (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 filed 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 that 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


                                      13.


                  Acquiring Person has any continuing agreement, arrangement or
                  understanding regarding the transferred Rights or (B) a
                  transfer which the Board of Directors 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 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


                                      14.


                           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 (for a period expiring within 45
                  calendar days after such record date) 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 consideration
                  part or all of which shall be in a form other than cash, the
                  value of such consideration shall be as determined in good
                  faith by the Board of Directors, whose determination shall be
                  described in a statement filed with the Rights Agent.
                  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


                                      15.


                  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,
                  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 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.


                                      16.


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


                                      17.


         (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, and shall promptly give the Rights
                  Agent a copy of such announcement. 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


                                      18.


                  registered in the names of the holders of record of Right
                  Certificates on the record date specified in the public
                  announcement.

         (j)      Irrespective of any adjustment or change in the Purchase Price
                  or the number of one one-hundredths of a Preferred Share
                  issuable upon the exercise of the Rights, the Right
                  Certificates theretofore and thereafter issued may continue to
                  express the Purchase Price and the number of one
                  one-hundredths of a Preferred Share which were expressed in
                  the initial Right Certificates issued hereunder.

         (k)      Before taking any action that would cause an adjustment
                  reducing the Purchase Price below 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 (and shall give prompt written notice of such election
                  to the Rights Agent) 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),


                                      19.


                  hereafter made by the Company to holders of its Preferred
                  Shares shall not be taxable to such stockholders.

         (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 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 and computations 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 have no duty
with respect to 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 Stockholder, or if in such
                  merger or consolidation all holders of Common Stock are not
                  treated alike, any other Person, (y) any Interested
                  Stockholder, 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


                                      20.


                  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
                  Stockholder or Stockholders, 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 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 Section 13(a) hereof, the Person that
                           is the issuer of any securities into


                                      21.


                           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 clause
                           (z) 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 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;


                                      22.


                  (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 that 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, 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 stockholders 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


                                      23.


                  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. 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 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 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


                                      24.


                  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).

         (e)      Whenever a payment for fractional Rights or fractional shares
                  is to be made by the Rights Agent, the Company shall (i)
                  promptly prepare and deliver to the Rights Agent a certificate
                  setting forth in reasonable detail the facts related to such
                  payments and the prices and/or formulas utilized in
                  calculating such payments and (ii) provide sufficient monies
                  to the Rights Agent in the form of fully collected funds to
                  make such payments. The Rights Agent shall be fully protected
                  in relying upon such a certificate and shall have no duty with
                  respect to, and shall not be deemed to have knowledge of any
                  payment for fractional Rights or fractional shares under any
                  Section of this Agreement relating to the payment of
                  fractional Rights or fractional shares unless and until the
                  Rights Agent shall have received such a certificate and
                  sufficient monies.

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.


                                      25.


SECTION 16.       AGREEMENT OF RIGHT HOLDERS.  Every holder of a Right, by
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

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

         (b)      after the Distribution Date, the Right Certificates are
                  transferable (subject to the provisions of this Agreement)
                  only on the registry books of the Rights Agent if surrendered
                  at the office of the Rights Agent designated for such
                  purposes, 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 STOCKHOLDER. No holder,
as such, of any Right Certificate shall be entitled to vote, receive dividends
or be deemed for any purpose the holder of the Preferred Shares or any other
securities of the Company which may at any time be issuable on the exercise of
the Rights represented thereby, nor shall anything contained herein or in any
Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 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 preparation,
administration, execution, delivery and amendment of this Agreement and the
exercise and performance of its duties hereunder. The Company also agrees to
indemnify the Rights Agent for, and to hold it harmless against, any loss,
liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or
expense, incurred without gross negligence, bad faith or willful misconduct
(each as determined by a final, non-appealable order, judgment, decree or ruling
of a court of competent jurisdiction) on the part of the Rights Agent, for any
action taken, suffered or omitted by the Rights Agent in connection with the
acceptance and administration of this Agreement, including, without limitation,
the costs and expenses of defending against any claim of liability hereunder.
The costs and expenses incurred by the Rights Agent in enforcing this right of
indemnification shall be paid by the Company unless it is determined by a final,
non-appealable order, judgment, decree or ruling of a court of


                                      26.


competent jurisdiction that the Rights Agent is not entitled to indemnification
due to the Rights Agent's gross negligence, bad faith or willful misconduct. The
provisions of this Section 18 and Section 20 below shall survive the expiration
of the Rights, the resignation or removal of the Rights Agent and the
termination of this Agreement.

                  The Rights Agent shall be authorized and protected and shall
                  incur no liability for, or in respect of any action taken,
                  suffered or omitted by it in connection with, its acceptance
                  and 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 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, punitive or
                  consequential loss or damage of any kind whatsoever
                  (including, but not limited, to lost profits), even if the
                  Rights Agent has been advised of such loss or damage. The
                  Rights Agent shall not be deemed to have knowledge of any
                  event of which it was supposed to receive notice thereof
                  hereunder, and the Rights Agent shall be fully protected and
                  shall incur no liability for failing to take any action in
                  connection therewith unless and until it has received such
                  notice in writing.

SECTION 19.       MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT. Any
Person into which the Rights Agent or any successor Rights Agent may be merged
or with which it may be consolidated, or any Person resulting from any merger or
consolidation to which the Rights Agent or any successor Rights Agent shall be a
party, or any Person 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 Person 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,


                                      27.


                  the Rights Agent may countersign such Right Certificates
                  either in its prior name or in its changed name; and in all
                  such cases such Right Certificates shall have the full force
                  provided in the Right Certificates and in this Agreement.

SECTION 20.       DUTIES OF RIGHTS AGENT. The Rights Agent undertakes only the
duties and obligations expressly imposed by this Agreement (and no implied
duties and obligations) 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 advice or
                  opinion of such counsel shall be full and complete
                  authorization and protection to the Rights Agent, and the
                  Rights Agent shall incur no liability for, or in respect of,
                  any action taken, suffered or omitted by it in accordance with
                  such advice or 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, suffering or omitting to take 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 authorization and protection to the Rights Agent for any
                  action taken, suffered or omitted 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 gross negligence, bad faith
                  or willful misconduct (each as determined by a final,
                  non-appealable order, judgment, decree or ruling of a court of
                  competent jurisdiction). Any liability of the Rights Agent
                  under this Agreement shall be limited to five times the amount
                  of fees paid by the Company to the Rights Agent.

         (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 or have
                  any liability 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


                                      28.


                  becoming void pursuant to Section 11(a)(ii) hereof), a
                  transfer to an Acquiring Person 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 such
                  instructions shall be full authorization and protection to the
                  Rights Agent, and the Rights Agent shall not be liable for any
                  action taken, suffered or omitted by it 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 any such action, the Rights Agent
                  has received written instructions in response to such
                  application specifying the action to be taken, suffered or
                  omitted.

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


                                      29.


         (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, absent gross
                  negligence, bad faith or willful misconduct (each as
                  determined by a final, non-appealable order, judgment, decree
                  or ruling of a court of competent jurisdiction) 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 it believes 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 Person organized and doing business under the laws of the United
States or of any other state of the United States that is authorized under such
laws to conduct shareholder services business 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) an Affiliate of a Person described in clause (a). 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


                                      30.


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, 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
                  of the Company pursuant to Section 23(b) hereof and shall not
                  be redeemed in any other manner.

         (b)

                  (i)      The Board of Directors may, at its option, at any
                           time prior to the earlier of (A) such time as any
                           Person becomes an Acquiring Person, or (B) the Final
                           Expiration Date, redeem all but not less than all of
                           the then outstanding Rights at a redemption price of
                           $.001 per Right, appropriately adjusted to reflect
                           any stock split, stock dividend 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


                                      31.


                           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 may, at its
                           option, at any time after the time a Person becomes
                           an Acquiring Person and after 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 Stockholder or a Transaction Person or
                           (y)(A) if and for so long as the Acquiring Person is
                           not thereafter the Beneficial Owner of 20% 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 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 (and shall give prompt written notice
                  of such redemption to the Rights Agent) 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 that 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.

         (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


                                      32.


                  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 null
                  and 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 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 holders 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 (with prompt written notice thereof to the Rights
                  Agent); 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 that 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


                                      33.


                  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 exchange of the Rights,
                  cash, 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 by
                  resolution 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 exchange under this
                  Section 24(c). In the event of any such suspension, the
                  Company shall issue a public announcement (with prompt written
                  notice thereof to the Rights Agent) 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.

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


                                      34.


                  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 (and to
                  the Rights Agent), 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.

increase the Rights Agent's rights, duties, liabilities or obligations, the

Agreement). All such actions, calculations, interpretations and determinations
(including, for purposes of clause (y) below, all omissions with respect to the
foregoing) which are done or made by the Board in good faith, shall (x) be

                         KOSAN BIOSCIENCES INCORPORATED
                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

                           (Exhibit C to Rights Plan)


                  On October 5, 2001, the Board of Directors of KOSAN
                  BIOSCIENCES INCORPORATED (the "Company") declared a dividend
                  of one preferred share purchase right (a "Right") for each
                  outstanding share of common stock, par value $.001 per share
                  (the "Common Shares"), of the Company. The dividend is
                  effective as of October 29, 2001 (the "Record Date") with
                  respect to the stockholders 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, par value $.001 per
                  share (the "Preferred Shares"), of the Company at a price of
                  $70.00 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 October 5, 2001 (the "Rights
                  Agreement"), between the Company and Mellon Investor Services
                  LLC (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 20% 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 20% or more of the outstanding Common
                  Shares.

                  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


                                      iii.


                  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
                  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 October 29, 2011 (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 stockholder 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


                                       C-2


                  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 $.001 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


                                      C-3


                  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 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).
