                                RIGHTS AGREEMENT

      THE RIGHTS AGREEMENT as entered into August 30, 2002 (the "Agreement"),
between Centene Corporation a Delaware corporation (the "Company"), and Mellon
Investor Services LLC, a New Jersey limited liability company, as Rights Agent
(the "Rights Agent").

                                   WITNESSETH

     WHEREAS, on August 26, 2002 the Board of Directors of the Company (the
"Board") authorized and declared a dividend distribution of one Right (as
hereinafter defined) for each share of Common Stock (as hereinafter defined) of
the Company outstanding at the Close of Business on September 10, 2002 (the
"Record Date"), and authorized the issuance of one Right (as such number may
hereinafter be adjusted pursuant to the provisions of Section 11(i) or (p)) for
each share of Common Stock issued between the Record Date (whether originally
issued or delivered from the Company's treasury) and the earlier of the
Distribution Date (as hereinafter defined) or the Expiration Date (as
hereinafter defined), each Right initially representing the right to purchase
one one-thousandth of a share of Preferred Stock (as hereinafter defined) having
the rights, powers and preferences set forth in the form of Certificate of
Designations attached hereto as EXHIBIT A, upon the terms and subject to the
conditions hereinafter set forth (the "Rights");

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

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

          (a) "Acquiring Person" shall mean any Person who or which, together
     with all Affiliates and Associates of such Person, shall be the Beneficial
     Owner of 15% or more of the shares of Common Stock then outstanding, but
     shall not include (i) the Company, (ii) any Subsidiary of the Company,
     (iii) any employee benefit plan of the Company or of any Subsidiary of the
     Company, or (iv) any Person organized, appointed or established by the
     Company for or pursuant to the terms of any such plan. Notwithstanding the
     foregoing, (x) no Person shall become an "Acquiring Person" as the result
     of an acquisition of Common Stock by the Company that, by reducing the
     number of shares outstanding, increases the proportionate number of shares
     beneficially owned by such Person to 15% or more of the shares of Common
     Stock of the Company then outstanding; provided, however that if a Person
     shall become the Beneficial Owner of 15% or more of the shares of Common
     Stock of the Company then outstanding as the result of an acquisition of
     Common Stock 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 Stock of the Company
     and shall then beneficially own 15% or more of the shares of Common Stock
     then outstanding, then such Person shall be deemed to be an "Acquiring
     Person" and (y) if the Board 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), but in any event within 15 Business Days, following
     receipt of written notice from the Company of such event, of Beneficial
     Ownership of a sufficient number of shares of Common Stock 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
     unless and until such Person shall again become an "Acquiring Person."

          (b) "Act" shall mean the Securities Act of 1933, as amended.

                                       -1-


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

          (d) "Adjustment Shares" shall have the meaning set forth in Section
     11(a)(ii).

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

              (i)   such Person or any of such Person's Affiliates or
                    Associates, directly or indirectly, owns or has 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), whether or not in writing, or upon the exercise
                    of conversion rights, exchange rights, other rights,
                    warrants or options, or otherwise; provided, however, that a
                    Person shall not be deemed the "Beneficial Owner" of, or to
                    "beneficially own," (A) 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) securities issuable upon exercise of Rights at any
                    time prior to the occurrence of a Triggering Event, or (C)
                    securities issuable upon exercise of Rights from and after
                    the occurrence of a Triggering Event which Rights were
                    acquired by such Person or any of such Person's Affiliates
                    or Associates prior to the Distribution Date or pursuant to
                    Section 3(a) or 22 (the "Original Rights") or pursuant to
                    Section 11(i) in connection with an adjustment made with
                    respect to any Original Rights;

             (ii)   such Person or any of such Person's Affiliates or
                    Associates, directly or indirectly, has the right to vote or
                    dispose of or has "beneficial ownership" of (as determined
                    pursuant to Rule 13d-3 of the General Rules and Regulations
                    under the Exchange Act, or any comparable or successor
                    rule), including 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), whether or
                    not in writing; provided, however, that a Person shall not
                    be deemed the "Beneficial Owner" of, or to "beneficially
                    own," any security under this subparagraph (ii) as a result
                    of an agreement, arrangement or understanding to vote such
                    security if such agreement, arrangement or understanding:
                    (A) arises solely from a revocable proxy or consent given in
                    response to a public proxy or consent solicitation made
                    pursuant to, and in accordance with, the applicable
                    provisions of the General Rules and Regulations under the
                    Exchange Act, and (B) is not then reportable by such Person
                    on Schedule 13D under the Exchange Act (or any comparable or
                    successor report); or

             (iii)  are beneficially owned, directly or indirectly, by any
                    other Person (or any Affiliate or Associate thereof) with
                    which such Person (or any of such Person's Affiliates or
                    Associates) has any agreement, arrangement or understanding
                    (other than customary agreements with and between
                    underwriters and selling group members with respect to a
                    bona fide public offering of securities) whether or not in
                    writing, for the purpose of acquiring, holding, voting
                    (except pursuant to a revocable proxy or consent as
                    described in the proviso to subparagraph (ii) of this
                    paragraph (e)) or disposing of any voting securities of the

     3.   ISSUANCE OF RIGHTS

          (a) Until the earlier of (i) the Close of Business on the tenth
     Business Day (or such later date as may be determined by the Board) after
     the Stock Acquisition Date (or, if the tenth Business Day after the Stock
     Acquisition Date occurs before the Record Date, the Close of Business on
     the Record Date), or (ii) the Close of Business on the tenth Business Day
     (or such later date as may be determined by action of the Board) after the
     date that a tender or exchange offer (other than a Permitted Offer) by 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
     Person organized, appointed or established by the Company for or pursuant
     to the terms of any such plan) is first published or sent or given within
     the meaning of Rule 14d-2 of the General Rules and Regulations under the
     Exchange Act, if upon consummation thereof, such Person would be the
     Beneficial Owner of 15% or more of the shares of Common Stock then
     outstanding (the earlier of (i) and (ii) being herein referred to as the
     "Distribution Date"), (x) the Rights will be evidenced by the certificates
     for the Common Stock registered in the names of the holders of the Common
     Stock (which certificates for Common Stock shall be deemed also to be
     certificates for Rights) and not by separate certificates, and (y) the
     Rights will be transferable only in connection with the transfer of the
     underlying shares of Common Stock (including a transfer to the Company). As
     soon as practicable after the Distribution Date and receipt by the Rights
     Agent of (i) written notice of the occurrence of the Distribution Date and
     (ii) a list of the shareholders (with addresses) of Common Stock, the
     Rights Agent will send by first-class, insured, postage prepaid mail, to
     each record holder of the Common Stock as of the Close of Business on the
     Distribution Date, at the address of such holder shown on the records of
     the Company, one or more rights certificates, in substantially the form of
     EXHIBIT B hereto (the "Rights Certificates"), evidencing one Right for each
     share of Common Stock so held, subject to adjustment as provided herein.
     With respect to certificates for the Common Stock outstanding as of the
     Close of Business on the Record Date, until the Distribution Date, the
     Rights will be evidenced by such certificates for the Common Stock and the
     registered holders of the Common Stock shall also be the registered holders
     of the associated Rights. In addition, in connection with the issuance or
     sale of shares of Common Stock following the Distribution Date and prior to
     the redemption or expiration of the Rights, the Company (i) shall, with
     respect to shares of Common Stock so issued or sold pursuant to the
     exercise of stock options or under any employee benefit plan or
     arrangement, or upon the exercise, conversion or exchange of securities
     granted or issued by the Company prior to the Distribution Date, and (ii)
     may, in any other case, if deemed necessary or appropriate by the Board,
     issue Rights Certificates representing the appropriate number of Rights in
     connection with such issuance or sale; provided, however, that (x) no such
     Rights Certificate shall be issued if, and to the extent that, the Company
     shall be advised by counsel that such issuance would create a significant
     risk of material adverse tax consequences to the Company or the Person to
     whom such Rights Certificate would be issued, and (y) no such Rights
     Certificate shall be issued if, and to the extent that, appropriate
     adjustment shall otherwise have been made in lieu of the issuance thereof.
     In the event that an adjustment in the number of Rights per share of Common
     Stock has been made pursuant to Section 11(i) or 11(p), at the time of
     distribution of the Rights Certificates, the Company shall make the
     necessary and appropriate rounding adjustments (in accordance with Section
     14(a)) so that Rights Certificates representing only whole

                                      -5-

     numbers of Rights are distributed and cash is paid in lieu of any
     fractional Rights. As of and after the Distribution Date, the Rights will
     be evidenced solely by such Rights Certificates.

          (b) As promptly as practicable following the Record Date, the Company
     will send a copy of a Summary of Rights to Purchase Preferred Stock, in
     substantially the form attached hereto as EXHIBIT C, by first-class,
     postage prepaid mail, to each record holder of the Common Stock as of the
     Close of Business on the Record Date, at the address of such holder shown
     on the records of the Company. The failure to send a copy of the Summary of
     Rights shall not affect the enforceability of any part of this Rights
     Agreement or the rights of any holder of the Rights.

          (c) Rights shall be issued (i) in respect of all shares of Common
     Stock that are issued (either as an original issuance or from the Company's
     treasury) after the Record Date but prior to the earlier of the
     Distribution Date or the Expiration Date and (ii) in connection with the
     issuance or sale of shares of Common Stock following the Distribution Date
     and prior to the redemption or expiration of the Rights (x) with respect to
     shares of Common Stock so issued or sold pursuant to the exercise of stock
     options or under any employee benefit plan or arrangement, or upon the
     exercise, conversion or exchange of securities, granted or issued by the
     Company prior to the Distribution Date and (y) with respect to shares of
     Common Stock so issued or sold in any other case, if deemed necessary or
     appropriate by the Board. Certificates representing such shares of Common
     Stock (including certificates issued upon transfer or exchange of Common
     Stock) shall also be deemed to be certificates for Rights, and shall bear
     the following legend:

                  This certificate also evidences and entitles the holder hereof
                  to certain Rights as set forth in the Rights Agreement between
                  Centene Corporation (the "Company"), and Mellon Investor
                  Services LLC, as Rights Agent (the "Rights Agent"), dated as
                  of August 30, 2002, as the same may be amended, restated or
                  renewed 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 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, as in effect on
                  the date of mailing, without charge promptly after receipt of
                  a written request therefor. Under certain circumstances set
                  forth in the Rights Agreement, Rights issued to, or held by,
                  any Person who is, was or becomes an Acquiring Person or any
                  Affiliate or Associate thereof (as such terms are defined in
                  the Rights Agreement), whether currently held by or on behalf
                  of such Person or by any subsequent holder, may become null
                  and void.

      With respect to such certificates containing the foregoing legend, until
      the earlier of (i) the Distribution Date and (ii) the Expiration Date, the
      Rights associated with the Common Stock represented by such certificates
      shall be evidenced by such certificates alone and registered holders of
      Common Stock shall also be the registered holders of the associated
      Rights. 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.

          (d) Until the earlier of the Distribution Date and the Expiration
     Date, the transfer of any certificates representing shares of Common Stock
     in respect of which Rights have been issued shall also constitute the
     transfer of the Rights associated with such shares of Common Stock. In the
     event that the Company purchases or acquires any shares of Common Stock
     after the Record Date but

                                      -6-


     prior to the Distribution Date, any Rights associated with such shares
     of Common Stock shall be deemed cancelled and retired so that the Company
     shall not be entitled to exercise any Rights associated with the shares of
     Common Stock that are no longer outstanding.

     4. FORM OF RIGHTS CERTIFICATES.

          (a) The Rights Certificates (and the forms of election to purchase,
     certification and assignment to be printed on the reverse thereof) shall
     each be substantially in the form set forth in EXHIBIT B hereto and may
     have such marks of identification or designation and such legends,
     summaries or endorsements printed thereon as the Company may deem
     appropriate, which do not affect the rights, duties, obligations 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 over-the-counter market 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, the Rights
     Certificates, whenever distributed, shall entitle the holders thereof to
     purchase such number of one one-thousandths of a share of Preferred Stock
     as shall be set forth therein at the price set forth therein (such exercise
     price per one one-thousandth of a share, the "Purchase Price"), but the
     amount and type of securities purchasable upon the exercise of each Right
     and the Purchase Price thereof shall be subject to adjustment as provided
     herein.

          (b) Any Rights Certificate issued pursuant to Section 3, 11(i) or 22
     that represents Rights beneficially owned by persons known to be: (i) an
     Acquiring Person or an Associate or Affiliate of an Acquiring Person, (ii)
     a transferee of an Acquiring Person (or of any such Associate or Affiliate)
     who becomes a transferee after the Acquiring Person becomes such, or (iii)
     a transferee of an Acquiring Person (or of any such Associate or Affiliate)
     who becomes a transferee prior to or concurrently with the Acquiring Person
     becoming such and receives such Rights pursuant to either (A) a transfer
     (whether or not for consideration) from the Acquiring Person to holders of
     equity interests in such Acquiring Person or to any Person with whom such
     Acquiring Person has any continuing agreement, arrangement or understanding
     (whether or not in writing) regarding the transferred Rights or (B) a
     transfer that the Board has determined is part of a plan, arrangement or
     understanding (whether or not in writing) that has as a primary purpose or
     effect avoidance of Section 7(e), and any Rights Certificate issued
     pursuant to Section 6 or 11 upon transfer, exchange, replacement or
     adjustment of any other Rights Certificate referred to in this sentence,
     shall contain (to the extent feasible) the following legend:

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

     The provisions of Section 7(e) shall be operative whether or not the
     foregoing legend is contained on any such Rights Certificate.

     5. COUNTERSIGNATURE AND REGISTRATION.

          (a) The Rights Certificates shall be executed on behalf of the Company
     by its Chairman of the Board, President or any Vice President, either
     manually or by facsimile signature, and shall have affixed thereto the
     Company's seal or a facsimile thereof, which shall be attested by the
     Secretary or an Assistant Secretary of the Company, either manually or by
     facsimile signature. The Rights

                                      -7-


     Certificates shall be manually countersigned by the Rights Agent and
     shall not be valid for any purpose unless so countersigned. In case any
     officer of the Company who shall have signed any of the Rights Certificates
     shall cease to be such officer of the Company before countersignature by
     the Rights Agent and issuance and delivery by the Company, such Rights
     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 Rights Certificates had not ceased to be
     such officer of the Company; and any Rights Certificates may be signed on
     behalf of the Company by any person who, at the actual date of the
     execution of such Rights Certificate, shall be a proper officer of the
     Company to sign such Rights Certificate, although at the date of the
     execution of this Rights Agreement any such person was not such an officer.

          (b) Following the Distribution Date and receipt by the Rights Agent of
     all relevant information, the Rights Agent shall keep or cause to be kept,
     at its office designated as the appropriate place for surrender of Rights
     Certificates upon exercise or transfer, books for registration and transfer
     of the Rights Certificates issued hereunder. Such books shall show the
     names and addresses of the respective holders of the Rights Certificates,
     the number of Rights evidenced on its face by each of the Rights
     Certificates, the Rights Certificate number and the date of each of the
     Rights Certificates.

     6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHTS CERTIFICATES;
MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

          (a) Subject to the provisions of Sections 4(b), 7(e) and 14, at any
     time after the Close of Business on the Distribution Date, and at or prior
     to the Close of Business on the Expiration Date, any Rights Certificate or
     Certificates (other than Rights Certificates representing Rights that have
     become null and void pursuant to Section 7(e) or that have been exchanged
     pursuant to Section 24) may be transferred, split up, combined or exchanged
     for another Rights Certificate or Certificates, entitling the registered
     holder to purchase a like number of one one-thousandths of a share of
     Preferred Stock (or, following a Triggering Event, Common Stock, other
     securities, cash or other assets, as the case may be) as the Rights
     Certificate or Certificates surrendered then entitled such holder (or
     former holder in the case of a transfer) to purchase. Any registered holder
     desiring to transfer, split up, combine or exchange any Rights Certificate
     or Certificates shall make such request in writing delivered to the Rights
     Agent, and shall surrender the Rights Certificate or Certificates to be
     transferred, split up, combined or exchanged, with the form of assignment
     and certificate appropriately executed, 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 Rights Certificate until the registered holder shall
     have completed and signed the certificate contained in the form of
     assignment on the reverse side of such Rights 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 Sections 4(b), 7(e) and 14, countersign and deliver
     to the Person entitled thereto a Rights Certificate or Rights 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
     Rights Certificates. The Rights Agent shall have no duty or obligation
     under this Section unless and until it is satisfied that all such taxes
     and/or governmental charges have been paid.

          (b) Upon receipt by the Company and the Rights Agent of evidence
     reasonably satisfactory to them of the loss, theft, destruction or
     mutilation of a Rights Certificate, and, in case of loss, theft or
     destruction, of indemnity or security satisfactory to them, and
     reimbursement to the Company and the Rights

                                      -8-


     Agent of all reasonable expenses incidental thereto, and upon
     surrender to the Rights Agent and cancellation of the Rights Certificate if
     mutilated, the Company will execute and deliver a new Rights Certificate of
     like tenor to the Rights Agent for countersignature and delivery to the
     registered owner in lieu of the Rights Certificate so lost, stolen,
     destroyed or mutilated.

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

          (a) Subject to Section 7(e), the registered holder of any Rights
     Certificate may exercise the Rights evidenced thereby (except as otherwise
     provided herein including the restrictions on exercisability set forth in
     Sections 9(c), 11(a)(iii) and 23) in whole or in part at any time after the
     Distribution Date upon surrender of the Rights Certificate, with the form
     of election to purchase and the certificate on the reverse side thereof
     duly executed, to the Rights Agent at the office of the Rights Agent
     designated for such purpose, together with payment of the aggregate
     Purchase Price with respect to the total number of one one-thousandths of a
     share of Preferred Stock (or other shares, securities, cash or other
     assets, as the case may be) as to which such surrendered Rights are then
     exercisable, at or prior to the earliest of (i) the Final Expiration Date,
     (ii) the time at which the Rights expire as provided in Section 13(d),
     (iii) the time at which the Rights are redeemed as provided in Section 23
     (the "Redemption Date") and (iv) the time at which such Rights are
     exchanged as provided in Section 24 (the earliest of (i), (ii), (iii) and
     (iv) being herein referred to as the "Expiration Date").

          (b) The Purchase Price for each one one-thousandth of a share of
     Preferred Stock pursuant to the exercise of a Right shall initially be
     $170.00 and shall be subject to adjustment from time to time as provided in
     Sections 11 and 13(a) and shall be payable in lawful money of the United
     States of America in accordance with paragraph (c) below.

          (c) Upon receipt of a Rights Certificate representing exercisable
     Rights, with the form of election to purchase and the certificate duly
     executed, accompanied by payment, with respect to each Right so exercised,
     of the Purchase Price per one one-thousandth of a share of Preferred Stock
     (or other shares, securities, cash or other assets, as the case may be) to
     be purchased and an amount equal to any applicable tax or governmental
     charge, the Rights Agent shall, subject to Section 20(k), thereupon
     promptly (i) (A) requisition from any transfer agent of the shares of
     Preferred Stock (or make available, if the Rights Agent is the transfer
     agent for such shares) certificates for the total number of one
     one-thousandths of a share of Preferred Stock to be purchased and the
     Company hereby authorizes its transfer agent to comply with such requests,
     or (B) if the Company shall have elected to deposit the total number of
     shares of Preferred Stock issuable upon exercise of the Rights hereunder
     with a depositary agent, requisition from the depositary agent depositary
     receipts representing such number of one one-thousandths of a share of
     Preferred Stock as are to be purchased (in which case certificates for the
     shares of Preferred Stock 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 requests, (ii) requisition
     from the Company the amount of cash, if any, to be paid in lieu of
     fractional shares in accordance with Section 14, (iii) after receipt of
     such certificates or depositary receipts, cause the same to be delivered to
     or upon the order of the registered holder of such Rights Certificate,
     registered in such name or names as may be designated by such holder, and
     (iv) after receipt thereof, deliver such cash, if any, to or upon the order
     of the registered holder of such Rights Certificate. The payment of the
     Purchase Price (as such amount may be reduced pursuant to Section
     11(a)(iii)) may be made in cash or by certified bank check or money order
     payable to the order of the Company. In the event that the Company is
     obligated to issue other securities (including Common Stock) of the
     Company, pay cash and/or distribute other property pursuant to Section
     11(a), the Company shall make all arrangements necessary so that such other
     securities, cash and/or other property are available for distribution by
     the Rights Agent, if and when necessary to comply with this Agreement.

                                      -9-




          (d) In case the registered holder of any Rights Certificate shall
     exercise less than all the Rights evidenced thereby, a new Rights
     Certificate evidencing Rights equivalent to the Rights remaining
     unexercised shall be issued by the Rights Agent and delivered to, or upon
     the order of, the registered holder of such Rights Certificate, registered
     in such name or names as may be designated by such holder, subject to the
     provisions of Sections 6 and 14.

          (e) Notwithstanding anything in this Agreement to the contrary, from
     and after the first occurrence of a Section 11(a)(ii) Event, any Rights
     beneficially owned by (i) an Acquiring Person or an Associate or Affiliate
     of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any
     such Associate or Affiliate) who becomes a transferee after the Acquiring
     Person becomes such, or (iii) a transferee of an Acquiring Person (or of
     any such Associate or Affiliate) who becomes a transferee prior to or
     concurrently with the Acquiring Person becoming such and receives such
     Rights pursuant to either (A) a transfer (whether or not for consideration)
     from the Acquiring Person to holders of equity interests in such Acquiring
     Person or to any Person with whom the Acquiring Person has any continuing
     agreement, arrangement or understanding (whether or not in writing)
     regarding the transferred Rights or (B) a transfer that the Board has
     determined is part of a plan, arrangement or understanding (whether or not
     in writing) that has as a primary purpose or effect avoidance of this
     Section 7(e), shall become null and void without any further action and no
     holder of such Rights shall have any rights whatsoever with respect to such
     Rights, whether under any provision of this Agreement or otherwise. No
     Rights Certificate shall be issued at any time upon the transfer of any
     Rights to an Acquiring Person whose Rights would be null and 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 Rights
     Certificate delivered to the Rights Agent for transfer to an Acquiring
     Person whose Rights would be null and void pursuant to the preceding
     sentence shall be cancelled. The Company shall notify the Rights Agent when
     this Section 7(e) applies and shall use all reasonable efforts to insure
     that the provisions of this Section 7(e) and Section 4(b) are complied
     with, but neither the Company nor the Rights Agent shall have any liability
     to any holder of Rights Certificates or other Person as a result of the
     Company's failure to make any determinations with respect to an Acquiring
     Person or its Affiliates, Associates or transferees hereunder.

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

     8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All Rights
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights
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 Rights Certificate purchased or acquired by the Company
otherwise than upon the exercise thereof. The Rights Agent shall deliver all
cancelled Rights Certificates to the Company, or shall, at the written request
of the Company, destroy such cancelled Rights Certificates, and in such case
shall deliver a certificate of destruction thereof to the Company.

                                      -10-


     9. RESERVATION AND AVAILABILITY OF CAPITAL STOCK.

          (a) The Company covenants and agrees that it will cause to be reserved
     and kept available out of its authorized and unissued shares of Preferred
     Stock (and, following the occurrence of a Triggering Event, out of its
     authorized and unissued shares of Common Stock and/or other securities or
     out of its authorized and issued shares held in its treasury), the number
     of shares of Preferred Stock (and, following the occurrence of a Triggering
     Event, Common Stock and/or other securities) that, as provided in this
     Agreement including Section 11(a)(iii), will be sufficient to permit the
     exercise in full of all outstanding Rights.

          (b) So long as the shares of Preferred Stock (and, following the
     occurrence of a Section 11(a)(ii) Event, Common Stock and/or other
     securities) issuable and deliverable upon the exercise of the Rights may be
     listed on any national securities exchange or automated 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 so listed upon official notice of issuance upon such exercise.

          (c) The Company shall use its best efforts to (i) file, as soon as
     practicable following the earliest date after the first occurrence of a
     Section 11(a)(ii) Event on which the consideration to be delivered by the
     Company upon exercise of the Rights has been determined in accordance with
     Section 11(a)(iii), or as soon as is required by law following the
     Distribution Date, as the case may be, a registration statement under the
     Act, with respect to the securities purchasable upon exercise of the Rights
     on an appropriate form, (ii) cause such registration statement to become
     effective as soon as practicable after such filing, (iii) cause such
     registration statement to remain effective (with a prospectus at all times
     meeting the requirements of the Act) until the earlier of (A) the date as
     of which the Rights are no longer exercisable for such securities, and (B)
     the Expiration Date, and (iv) obtain such other regulatory approvals as may
     be necessary for it to issue securities purchasable upon the exercise of
     the Rights. The Company will also take such action as may be appropriate
     under, or to ensure compliance with, the securities or "blue sky" laws of
     the various states in connection with the exercisability of the Rights. The
     Company may temporarily suspend, for a period of time not to exceed ninety
     (90) days after the date set forth in clause (i) of the first sentence of
     this Section 9(c), the exercisability of the Rights in order to prepare and
     file such registration statement and permit it to become effective or to
     obtain any other required regulatory approval in connection with the
     exercisability of the Rights. Upon any such suspension, the Company shall
     promptly notify the Rights Agent thereof and shall issue a public
     announcement stating that the exercisability of the Rights has been
     temporarily suspended, as well as a public announcement (with prompt notice
     thereof to the Rights Agent) at such time as the suspension is no longer in
     effect. Notwithstanding any provision of this Agreement to the contrary,
     the Rights shall not be exercisable in any jurisdiction unless the
     requisite registration or qualification in such jurisdiction shall have
     been effected or obtained.

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

          (e) The Company further covenants and agrees that it will pay when due
     and payable any and all taxes and charges that may be payable in respect of
     the issuance or delivery of the Rights Certificates and of any certificates
     for a number of one one-thousandths of a share of Preferred Stock (or
     Common Stock and/or other securities, as the case may be) upon the exercise
     of Rights. The Company shall not, however, be required (i) to pay any tax
     or charge that may be payable in

                                      -11-


     respect of any transfer or delivery of Rights Certificates to a Person
     other than, or the issuance or delivery of a number of one one-thousandths
     of a share of Preferred Stock (or Common Stock and/or other securities, as
     the case may be) in respect of a name other than that of, the registered
     holder of the Rights Certificate evidencing Rights surrendered for exercise
     or (ii) to issue or deliver any certificates for a number of one
     one-thousandths of a share of Preferred Stock (or Common Stock and/or other
     securities, as the case may be) in a name other than that of the registered
     holder upon the exercise of any Rights until such tax or charge shall have
     been paid (any such tax or charge being payable by the holder of such
     Rights Certificate at the time of surrender) or until it has been
     established to the Company's satisfaction that no such tax or charge is
     due.

     10. PREFERRED STOCK RECORD DATE. Each Person in whose name any certificate
for a number of one one-thousandths of a share of Preferred Stock (or Common
Stock and/or other securities, as the case may be) is issued upon the exercise
of Rights shall for all purposes be deemed to have become the holder of record
of such fractional shares of Preferred Stock (or Common Stock and/or other
securities, as the case may be) represented thereby on, and such certificate
shall be dated, the date upon which the Rights Certificate evidencing such
Rights was duly surrendered with the forms of election and certification duly
executed and payment of the Purchase Price (and all applicable taxes or charges)
was made; provided, however, that if the date of such surrender and payment is a
date upon which the Preferred Stock (or Common Stock and/or other securities, as
the case may be) transfer books of the Company are closed, such Person shall be
deemed to have become the record holder of such shares (fractional or otherwise)
on, and such certificate shall be dated, the next succeeding Business Day on
which the Preferred Stock (or Common Stock and/or other securities, as the case
may be) transfer books of the Company are open. Prior to the exercise of the
Rights evidenced thereby, the holder of a Rights Certificate, as such, shall not
be entitled to any rights of a stockholder of the Company with respect to
securities for which the Rights shall be exercisable, including 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.

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

          (a) (i) In the event the Company shall at any time after the date of
     this Agreement (A) declare a dividend on the Preferred Stock payable in
     shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock,
     (C) combine the outstanding Preferred Stock into a smaller number of
     shares, or (D) issue any shares of its capital stock in a reclassification
     of the Preferred Stock (including any such reclassification in connection
     with a consolidation or merger in which the Company is the continuing or
     surviving corporation), except as otherwise provided in this Section 11(a)
     and Section 7(e), the Purchase Price in effect at the time of the record
     date for such dividend or of the effective date of such subdivision,
     combination or reclassification, and the number and kind of shares of
     Preferred Stock or capital stock, as the case may be, issuable on such
     date, shall be proportionately adjusted so that the holder of any Right
     exercised after such time shall be entitled to receive, upon payment of the
     Purchase Price then in effect, the aggregate number and kind of shares of
     Preferred Stock or capital stock, as the case may be, which, if such Right
     had been exercised immediately prior to such date and at a time when the
     Preferred Stock transfer books of the Company were open, he would have
     owned upon such exercise and been entitled to receive by virtue of such
     dividend, subdivision, combination or reclassification. If an event occurs
     that would require an adjustment under both this Section 11(a)(i) and
     Section 11(a)(ii), the adjustment provided for in this Section 11(a)(i)
     shall be in addition to, and shall be made prior to, any adjustment
     required pursuant to Section 11(a)(ii).

                                      -12-


               (i) Subject to Section 24 of this Agreement, in the event that
          any Person, alone or together with its Affiliates or Associates,
          becomes an Acquiring Person (other than pursuant to a Permitted
          Offer), then, promptly following the first occurrence of such event,
          proper provision shall be made so that each holder of a Right (except
          as provided below and in Section 7(e)) shall thereafter have the right
          to receive (subject to the last sentence of Section 23(a)), upon
          exercise thereof at the then current Purchase Price in accordance with
          the terms of this Agreement, in lieu of a number of one
          one-thousandths of a share of Preferred Stock, such number of shares
          of Common Stock of the Company that equals the result obtained by (x)
          multiplying the then current Purchase Price by the then number of one
          one-thousandths of a share of Preferred Stock for which a Right was
          exercisable immediately prior to the first occurrence of a Section
          11(a)(ii) Event, and (y) dividing that product (which, following such
          first occurrence, shall thereafter be referred to as the "Purchase
          Price" for each Right and for all purposes of this Agreement) by 50%
          of the current market price (determined pursuant to Section 11(d)) per
          share of Common Stock on the date of such first occurrence (such
          number of shares, the "Adjustment Shares").

               (ii) In the event that the number of shares of Common Stock that
          are authorized by the Company's Certificate of Incorporation but not
          outstanding or reserved for issuance for purposes other than upon
          exercise of the Rights are not sufficient to permit the exercise in
          full of the Rights in accordance with the foregoing subparagraph (ii)
          of this Section 11(a), the Company shall: (A) determine the excess of
          (1) the value of the Adjustment Shares issuable upon the exercise of a
          Right (the "Current Value") over (2) the Purchase Price (such excess,
          the "Spread"), and (B) with respect to each Right, make adequate
          provision to substitute for the Adjustment Shares, upon payment of the
          applicable Purchase Price, (1) cash, (2) a reduction in the Purchase
          Price, (3) Common Stock or other equity securities of the Company
          (including shares, or units of shares, of preferred stock that the
          Board has deemed to have the same value as shares of Common Stock
          (such shares of preferred stock, "common stock equivalents")), (4)
          debt securities of the Company, (5) other assets, or (6) any
          combination of the foregoing, having an aggregate value equal to the
          Current Value, where such aggregate value has been determined by the
          Board based upon the advice of a nationally recognized investment
          banking firm selected by the Board; provided, however, if the Company
          shall not have made adequate provision to - deliver value pursuant to
          clause (B) above within thirty days following the later of (x) the
          first occurrence of a Section 11(a)(ii) Event and (y) the date on
          which the Company's right of redemption pursuant to Section 23(a)
          expires (the later of (x) and (y) being referred to herein as the
          "Section 11(a)(ii) Trigger Date"), then the Company shall be obligated
          to deliver, upon the surrender for exercise of a Right and without
          requiring payment of the Purchase Price, shares of Common Stock (to
          the extent available) and then, if necessary, cash, which shares
          and/or cash have an aggregate value equal to the Spread. If the Board
          shall determine in good faith that it is likely that sufficient
          additional shares of Common Stock could be authorized for issuance
          upon exercise in full of the Rights, the thirty day period set forth
          above may be extended to the extent necessary, but not more than
          ninety (90) days after the Section 11(a)(ii) Trigger Date, in order
          that the Company may seek shareholder approval for the authorization
          of such additional shares (such period, as it may be extended, the
          "Substitution Period"). To the extent that the Company determines that
          some action need be taken pursuant to the first and/or second
          sentences of this Section 11(a)(iii), the Company (x) shall provide,
          subject to Section 7(e), that such action shall apply uniformly to all
          outstanding Rights, and (y) may suspend the exercisability of the
          Rights until the expiration of the Substitution Period in order to
          seek any authorization of additional shares and/or to decide the
          appropriate form of distribution to be made pursuant to such first
          sentence and to determine the value thereof. In the event of any such
          suspension, the Company shall promptly notify the Rights Agent of such
          suspension and shall issue a public announcement stating that the
          exercisability of the Rights has been temporarily suspended, as well
          as a public announcement

                                      -13-


          (with prompt notice thereof to the Rights Agent) at such time as
          the suspension is no longer in effect. For purposes of this Section
          11(a)(iii), the value of the Common Stock shall be the current market
          price (as determined pursuant to Section 11(d)) per share of the
          Common Stock on the Section 11(a)(ii) Trigger Date and the value of
          any "common stock equivalent" shall be deemed to have the same value
          as the Common Stock on such date.

          (b) In case the Company shall fix a record date for the issuance of
     rights, options or warrants to all holders of Preferred Stock entitling
     them to subscribe for or purchase (for a period expiring within forty-five
     (45) calendar days after such record date) Preferred Stock (or shares
     having the same rights, privileges and preferences as the shares of
     Preferred Stock ("equivalent preferred stock")) or securities convertible
     into Preferred Stock or equivalent preferred stock at a price per share of
     Preferred Stock or per share of equivalent preferred stock (or having a
     conversion price per share, if a security convertible into Preferred Stock
     or equivalent preferred stock) less than the current market price (as
     determined pursuant to Section 11(d)) per share of Preferred Stock 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 shares of Preferred Stock outstanding on such record date,
     plus the number of shares of Preferred Stock that the aggregate offering
     price of the total number of shares of Preferred Stock and/or equivalent
     preferred stock 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 shares of Preferred Stock outstanding on such record date, plus the
     number of additional shares of Preferred Stock and/or equivalent preferred
     stock to be offered for subscription or purchase (or into which the
     convertible securities so to be offered are initially convertible). In case
     such subscription price may be paid by delivery of consideration part or
     all of which may be in a form other than cash, the value of such
     consideration shall be as determined in good faith by the Board, whose
     determination shall be described in a statement filed with the Rights Agent
     and shall be conclusive for all purposes. Shares of Preferred Stock 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 that would then be in effect if
     such record date had not been fixed.

          (c) In case the Company shall fix a record date for a distribution to
     all holders of Preferred Stock (including any such distribution made in
     connection with a consolidation or merger in which the Company is the
     continuing corporation) of evidences of indebtedness, cash (other than a
     regular quarterly cash dividend out of the earnings or retained earnings of
     the Company), assets (other than a dividend payable in Preferred Stock, but
     including any dividend payable in stock other than Preferred Stock) or
     subscription rights or warrants (excluding those referred to in Section
     11(b)), the Purchase Price to be in effect after such record date shall be
     determined by multiplying the Purchase Price in effect immediately prior to
     such record date by a fraction, the numerator of which shall be the current
     market price (as determined pursuant to Section 11(d)) per share of
     Preferred Stock on such record date, less the fair market value (as
     determined in good faith by the Board, whose determination shall be
     described in a statement filed with the Rights Agent and shall be
     conclusive for all purposes) of the portion of the cash, assets or
     evidences of indebtedness so to be distributed or of such subscription
     rights or warrants applicable to a share of Preferred Stock and the
     denominator of which shall be such current market price (as determined
     pursuant to Section 11(d)) per share of Preferred Stock on such record
     date. 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 be adjusted to be the Purchase Price that would have
     been in effect if such record date had not been fixed.

                                      -14-

          (d) (i) For the purpose of any computation hereunder, other than
     computations made pursuant to Section 11(a)(iii), the "current market
     price" per share of Common Stock on any date shall be deemed to be the
     average of the daily closing prices per share of such Common Stock for the
     thirty consecutive Trading Days (as such term is hereinafter defined)
     immediately prior to such date, and for purposes of computations made
     pursuant to Section 11(a)(iii), the "current market price" per share of
     Common Stock on any date shall be deemed to be the average of the daily
     closing prices per share of such Common Stock for the ten consecutive
     Trading Days immediately following such date; provided, however, that in
     the event that the current market price per share of the Common Stock is
     determined during a period following the announcement by the issuer of such
     Common Stock of (A) a dividend or distribution on such Common Stock payable
     in shares of such Common Stock or securities convertible into shares of
     such Common Stock (other than the Rights), or (B) any subdivision,
     combination or reclassification of such Common Stock, and prior to the
     expiration of the requisite thirty Trading Day or ten Trading Day period,
     as set forth above, after the ex-dividend date for such dividend or
     distribution, or the record date for such subdivision, combination or
     reclassification occurs, then, and in each such case, the "current market
     price" shall be properly adjusted to take into account ex-dividend or post
     record date trading. 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 principal
     national securities exchange on which the shares of Common Stock are listed
     or admitted to trading or, if the shares of Common Stock are not listed or
     admitted to trading on any national securities exchange, the last quoted
     price or, if not so quoted, the average of the high bid and the 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 shares of Common Stock 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 Common Stock selected by the Board. All references in this Section to
     closing prices, last quoted prices or other stock prices mean prices during
     regular trading hours, without giving effect to any after-hours or extended
     hours trading. If on any such date no market maker is making a market in
     the Common Stock, the fair value of such shares on such date shall be as
     determined in good faith by the Board, whose determination shall be
     described in a statement filed with the Rights Agent and shall be
     conclusive for all purposes. The term "Trading Day" shall mean a day on
     which Nasdaq or any national securities exchange on which the shares of
     Common Stock are listed or admitted to trading is open for the transaction
     of business or, if the shares of Common Stock are not listed or admitted to
     trading on Nasdaq or any national securities exchange, a Business Day. If
     the Common Stock is not publicly held or not so listed or traded, "current
     market price" per share shall mean the fair value per share as determined
     in good faith by the Board, whose determination shall be described in a
     statement filed with the Rights Agent and shall be conclusive for all
     purposes.

              (ii) For the purpose of any computation hereunder, the "current
market price" per share of Preferred Stock shall be determined in the same
manner as set forth above for the Common Stock in clause (i) of this Section
11(d) (other than the last sentence thereof). If the current market price per
share of Preferred Stock cannot be determined in the manner provided above or if
the Preferred Stock is not publicly held or listed or traded in a manner
described in clause (i) of this Section 11(d), the "current market price" per
share of Preferred Stock shall be conclusively deemed to be an amount equal to
1000 (as such number may be appropriately adjusted for such events as stock
splits, stock dividends and recapitalizations with respect to the Common Stock
occurring after the date of this Agreement) multiplied by the current market
price per share of the Common Stock. If neither the Common Stock nor the
Preferred Stock is publicly held or so listed or traded, "current market price"
per share of the Preferred Stock shall mean the fair value per share as
determined in good faith by the Board, which determination shall be described in
a statement filed with the Rights Agent and shall be conclusive for all
purposes. For

                                      -15-

all purposes of this Agreement, the "current market price" of one one-thousandth
of a share of Preferred Stock shall be equal to the "current market price" of
one share of Preferred Stock divided by 1000.

          (e) Anything herein to the contrary notwithstanding, no adjustment in
     the Purchase Price shall be required unless such adjustment would require
     an increase or decrease of at least one percent in the Purchase Price;
     provided, however, that any adjustments that 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 ten-millionth of a
     share of Preferred Stock, or hundred-thousandth of a share of Common Stock
     or other 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 that mandates such adjustment, or (ii) the Expiration Date.

          (f) If as a result of an adjustment made pursuant to Section 11(a)(ii)
     or 13(a), the holder of any Right thereafter exercised shall become
     entitled to receive any securities other than Preferred Stock, thereafter
     the number of such other securities so receivable upon exercise of any
     Right and the Purchase Price thereof 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 Stock contained in Sections
     11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the provisions
     of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Stock shall
     apply on like terms to any such other securities; provided, however, that
     the Company shall not be liable for its inability to reserve and keep
     available for issuance upon exercise of the Rights pursuant to Section
     11(a)(ii) a number of shares of Common Stock greater than the number then
     authorized by the Company's Certificate of Incorporation but not
     outstanding or reserved for other purposes.

          (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-thousandths
     of a share of Preferred Stock 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), upon each adjustment of the Purchase Price as a result of
     the calculations made in Sections 11(b) and (c), each Right outstanding
     immediately prior to the making of such adjustment shall thereafter
     evidence the right to purchase, at the adjusted Purchase Price, that number
     of one one-thousandths of a share of Preferred Stock (calculated to the
     nearest ten-millionth) obtained by (i) multiplying (x) the number of one
     one-thousandths of a share covered by a Right immediately prior to this
     adjustment, by (y) the Purchase Price in effect immediately prior to such
     adjustment of the Purchase Price, and (ii) dividing the product so obtained
     by the Purchase Price in effect immediately after such adjustment of the
     Purchase Price.

          (i) The Company may elect on or after the date of any adjustment of
     the Purchase Price to adjust the number of Rights, in lieu of any
     adjustment in the number of one one-thousandths of a share of Preferred
     Stock purchasable upon the exercise of a Right. Each of the Rights
     outstanding after the adjustment in the number of Rights shall be
     exercisable for the number of one one-thousandths of a share of Preferred
     Stock 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-hundred-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 and promptly notify the
     Rights Agent of its election to adjust the number of Rights, indicating the
     record date for the adjustment, and, if known at the time, the amount of
     the adjustment to be made. This record date may be the date on which the
     Purchase Price

                                      -16-


     is adjusted or any day thereafter, but, if the Rights Certificates
     have been issued, shall be at least ten days later than the date of the
     public announcement. If Rights 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 Rights Certificates on such record date Rights
     Certificates evidencing, subject to Section 14, the additional Rights to
     which such holders shall be entitled as a result of such adjustment, or, at
     the option of the Company, shall cause to be distributed to such holders of
     record in substitution and replacement for the Rights Certificates held by
     such holders prior to the date of adjustment, and upon surrender thereof,
     if required by the Company, new Rights Certificates evidencing all the
     Rights to which such holders shall be entitled after such adjustment.
     Rights Certificates so to be distributed shall be issued, executed and
     countersigned in the manner provided for herein (and may bear, at the
     option of the Company, the adjusted Purchase Price) and shall be registered
     in the names of the holders of record of Rights 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-thousandths of a share of Preferred Stock issuable
     upon the exercise of the Rights, the Rights Certificates theretofore and
     thereafter issued may continue to express the Purchase Price per one
     one-thousandth of a share and the number of one one-thousandths of a share
     that were expressed in the initial Rights Certificates issued hereunder.

          (k) Before taking any action that would cause an adjustment reducing
     the Purchase Price below the then par value, if any, of the number of one
     one-thousandths of a share of Preferred Stock issuable upon exercise of the
     Rights, the Company shall take any corporate action that may, in the
     opinion of its counsel, be necessary in order that the Company may validly
     and legally issue such number of one one-thousandths of a share of fully
     paid and nonassessable Preferred Stock 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 promptly
     notify the Rights Agent of any such election) until the occurrence of such
     event the issuance to the holder of any Right exercised after such record
     date the number of one one-thousandths of a share of Preferred Stock and
     other capital stock or securities of the Company, if any, issuable upon
     such exercise over and above the number of one one-thousandths of a share
     of Preferred Stock 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
     (fractional or otherwise) or securities upon the occurrence of the event
     requiring such adjustment.

          (m) Anything in this Section 11 to the contrary notwithstanding, the
     Company shall be entitled to make such reductions in the Purchase Price, in
     addition to those adjustments expressly required by this Section 11, as and
     to the extent that in their good faith judgment the Board shall determine
     to be advisable in order that any (i) consolidation or subdivision of the
     Preferred Stock, (ii) issuance wholly for cash of any shares of Preferred
     Stock at less than the current market price, (iii) issuance wholly for cash
     of shares of Preferred Stock or securities that by their terms are
     convertible into or exchangeable for shares of Preferred Stock, (iv) stock
     dividends or (v) issuance of rights, options or warrants referred to in
     this Section 11, hereafter made by the Company to holders of its Preferred
     Stock shall not be taxable to such stockholders.

          (n) The Company covenants and agrees that it shall not, at any time
     after the Distribution Date, (i) consolidate with any other Person (other
     than a Subsidiary of the Company in a transaction that complies with
     Section 11(o)), (ii) merge with or into any other Person (other than a
     Subsidiary

                                      -17-


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

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

          (p) Anything in this Agreement to the contrary notwithstanding, in the
     event that the Company shall at any time after the Record Date and prior to
     the Distribution Date (i) declare or pay any dividend on the outstanding
     shares of Common Stock payable in shares of Common Stock, (ii) subdivide
     the outstanding shares of Common Stock, or (iii) combine the outstanding
     shares of Common Stock into a smaller number of shares, the number of
     Rights associated with each share of Common Stock then outstanding, or
     issued or delivered thereafter but prior to the Distribution Date, shall be
     proportionately adjusted so that the number of Rights thereafter associated
     with each share of Common Stock following any such event shall equal the
     result obtained by multiplying the number of Rights associated with each
     share of Common Stock immediately prior to such event by a fraction, the
     numerator of which shall be the number of shares of Common Stock
     outstanding immediately prior to the occurrence of such event and the
     denominator of which shall be the number of shares of Common Stock
     outstanding immediately following the occurrence of such event.

     12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES. Whenever an
adjustment is made as provided in Section 11 or 13, 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 Preferred Stock and the
Common Stock, a copy of such certificate, and (c) mail a brief summary thereof
to each holder of a Rights Certificate (or, if prior to the Distribution Date,
to each holder of a certificate representing shares of Common Stock) in
accordance with Section 26. The Rights Agent shall be fully protected in relying
on any such certificate and on any adjustment or statement therein contained and
shall have no duty or liability with respect to, and shall not be deemed to have
knowledge of, any adjustment or any such event unless and until it shall have
received such a certificate.

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

          (a) In the event that, at any time after a Person has become an
     Acquiring Person, (x) the Company shall consolidate with, or merge with and
     into, any other Person (other than a Subsidiary of the Company in a
     transaction that complies with Section 11(o)), and the Company shall not be
     the continuing or surviving corporation of such consolidation or merger,
     (y) any Person (other than a Subsidiary of the Company in a transaction
     that complies with Section 11(o)) shall consolidate with,

                                      -18-


     or merge with or into, the Company, and the Company shall be the
     continuing or surviving corporation of such consolidation or merger and, in
     connection with such consolidation or merger, all or part of the
     outstanding shares of Common Stock shall be changed into or exchanged for
     stock or other securities of any other Person or cash or any other
     property, or (z) the Company shall sell or otherwise transfer (or one or
     more of its Subsidiaries shall sell or otherwise transfer), in one
     transaction or a series of related transactions, assets or earning power
     aggregating more than 50% of the assets or earning power of the Company and
     its Subsidiaries (taken as a whole) to any Person or Persons (other than
     the Company or any Subsidiary of the Company in one or more transactions
     each of which complies with Section 11(o)), then, and in each such case and
     except as contemplated by Section 13(d), proper provision shall be made so
     that: (i) each holder of a Right, except as provided in Section 7(e), shall
     thereafter have the right to receive, upon the exercise thereof at the then
     current Purchase Price in accordance with the terms of this Agreement, such
     number of validly authorized and issued, fully paid, non-assessable and
     freely tradable shares of Common Stock of the Principal Party (as such term
     is hereinafter defined), which shall not be subject to any liens,
     encumbrances, rights of first refusal or other adverse claims, as shall be
     equal to the result obtained by (1) multiplying the then current Purchase
     Price by the number of one one-thousandths of a share of Preferred Stock
     for which a Right is exercisable immediately prior to the first occurrence
     of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred prior
     to the first occurrence of a Section 13 Event, multiplying the number of
     such one one-thousandths of a share for which a Right was exercisable
     immediately prior to the first occurrence of a Section 11(a)(ii) Event by
     the Purchase Price in effect immediately prior to such first occurrence),
     and (2) dividing that product (which, following the first occurrence of a
     Section 13 Event, shall be referred to as the "Purchase Price" for each
     Right and for all purposes of this Agreement) by 50% of the current market
     price (determined pursuant to Section 11(d)(i)) per share of the Common
     Stock of such Principal Party on the date of consummation of such Section
     13 Event; (ii) such Principal Party shall thereafter be liable for, and
     shall assume, by virtue of such Section 13 Event, all the obligations and
     duties of the Company pursuant to this Agreement; (iii) the term "Company"
     shall thereafter be deemed to refer to such Principal Party, it being
     specifically intended that, subject to clause (v) below, the provisions of
     Section 11 shall apply only to such Principal Party following the first
     occurrence of a Section 13 Event; (iv) such Principal Party shall take such
     steps (including, but not limited to, the reservation of a sufficient
     number of shares of its Common Stock) in connection with the consummation
     of any such transaction as may be necessary to assure that the provisions
     hereof shall thereafter be applicable, as nearly as reasonably may be, in
     relation to its shares of Common Stock thereafter deliverable upon the
     exercise of the Rights; and (v) the provisions of Section 11(a)(ii) shall
     be of no effect following the first occurrence of any Section 13 Event.

     (b)  "Principal Party" shall mean

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

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

      provided, however, that in any such case, (1) if the Common Stock of such
      Person is not at such time and has not been continuously over the
      preceding twelve-month period registered under Section 12 of the Exchange
      Act, and such Person is a direct or indirect Subsidiary of another Person
      the Common Stock of which is and has been so registered, "Principal Party"
      shall refer to such other

                                      -19-


     Person; (2) in case such Person is a Subsidiary, directly or indirectly,
     of more than one Person, the Common Stocks 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 Stock having the
     greatest aggregate market value; and (3) in case such Person is owned,
     directly or indirectly, by a joint venture formed by two or more Persons
     that are not owned, directly or indirectly, by the same Person, the rules
     set forth in (1) and (2) above shall apply to each of the chains of
     ownership having an interest in such joint venture as if such party were a
     "Subsidiary" of both or all of such joint ventures 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 shares of its Common Stock 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
     such Principal Party shall have executed and delivered to the Rights Agent
     a supplemental agreement providing for the terms set forth in paragraphs
     (a) and (b) of this Section 13 and further providing that, as soon as
     practicable after the date of any consolidation, merger or sale of assets
     mentioned in paragraph (a) of this Section 13, the Principal Party will

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

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

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

      The provisions of this Section 13 shall similarly apply to successive
      mergers or consolidations or sales or other transfers. In the event that a
      Section 13 Event shall occur at the same time as, or at any time after,
      the occurrence of a Section 11(a)(ii) Event, the Rights that have not
      theretofore been exercised shall thereafter become exercisable in the
      manner described in Section 13(a).

          (d) Notwithstanding anything in this Agreement to the contrary,
     Section 13 shall not be applicable to a transaction described in
     subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is
     consummated with a Person or Persons (or a wholly owned subsidiary of any
     such Person or Persons) who acquired shares of Common Stock pursuant to a
     Permitted Offer, (ii) the price per share of Common Stock paid in such
     transaction is not less than the price per share of Common Stock paid to
     all holders of shares of Common Stock whose shares were purchased pursuant
     to such Permitted Offer, and (iii) the form of consideration paid in such
     transaction is the same as the form of consideration paid pursuant to such
     Permitted Offer. Upon consummation of any such transaction contemplated by
     this Section 13(d), all Rights hereunder shall expire.

     14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

          (a) The Company shall not be required to issue fractions of Rights,
     except prior to the Distribution Date as provided in Section 11(i) or
     11(p), or to distribute Rights Certificates that

                                      -20-


     evidence fractional Rights. In lieu of such fractional Rights, there
     shall be paid to the registered holders of the Rights 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 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 of the Rights 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 principal national securities exchange on which the Rights are
     listed or admitted to trading, or if the Rights are not listed or admitted
     to trading on any national securities exchange, the last quoted price or,
     if not so quoted, the average of the high bid and the 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. All references in this Section to closing prices, last quoted
     prices or other stock prices means prices during regular trading hours,
     without giving effect to any after-hours or extended hours trading. 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 shall be used, which determination shall be described in a statement
     filed with Rights Agent and shall be conclusive for all purposes.

          (b) The Company shall not be required to issue fractions of shares of
     Preferred Stock (other than fractions that are integral multiples of one
     one-thousandth of a share of Preferred Stock) upon exercise of the Rights
     or to distribute certificates that evidence fractional shares of Preferred
     Stock (other than fractions that are integral multiples of one
     one-thousandth of a share of Preferred Stock). Fractional shares of
     Preferred Stock in integral multiples of one one-thousandth of a share of
     Preferred Stock 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 shares of Preferred Stock
     represented by such depositary receipts. In lieu of fractional shares of
     Preferred Stock (other than fractions that are integral multiples of one
     one-thousandth of a share of Preferred Stock), the Company shall pay to the
     registered holders of Rights 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 one-thousandth of a share of Preferred
     Stock. For purposes of this Section 14(b), the current market value of one
     one-thousandth of a share of Preferred Stock shall be one one-thousandth of
     the closing price of a share of Preferred Stock (as determined pursuant to
     Section 11(d)(ii)) for the Trading Day immediately prior to the date of
     such exercise.

          (c) Following the occurrence of a Triggering Event, the Company shall
     not be required to issue fractions of shares of Common Stock upon exercise
     of the Rights or to distribute certificates that evidence fractional shares
     of Common Stock. In lieu of fractional shares of Common Stock, the Company
     shall pay to the registered holders of Rights Certificates at the time such
     Rights are exercised as herein provided an amount in cash equal to the same
     fraction of the current market price of one share of Common Stock (as
     determined pursuant to Section 11(d)(i)) for the Trading Day immediately
     prior to the date of such exercise.

          (d) The holder of a Right by the acceptance of such Right expressly
     waives his right to receive any fractional Rights or any fractional shares
     upon exercise of a Right, except as permitted by this Section 14.

                                      -21-

     15. RIGHTS OF ACTION. All rights of action in respect of this Agreement,
except the rights of action expressly given to the Rights Agent, are vested in
the respective registered holders of the Rights Certificates (and, prior to the
Distribution Date, the registered holders of the Common Stock); and any
registered holder of any Rights Certificate (or, prior to the Distribution Date,
of the Common Stock), without the consent of the Rights Agent or of the holder
of any other Rights Certificate (or, prior to the Distribution Date, of the
Common Stock), 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 Rights Certificate in the manner provided in such Rights
Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and shall be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.

     16. AGREEMENT OF RIGHTS 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 Common Stock;

          (b) after the Distribution Date, the Rights Certificates are
              transferable 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 with the appropriate forms and certificates duly
              completed and fully executed;

          (c) subject to Sections 6(a) and 7(f), the Company and the Rights
              Agent may deem and treat the Person in whose name a Rights
              Certificate (or, prior to the Distribution Date, the associated
              Common Stock certificate) is registered as the absolute owner
              thereof and of the Rights evidenced thereby (notwithstanding any
              notations of ownership or writing on the Rights Certificates or
              the associated Common Stock certificate made by anyone other than
              the Company or the Rights Agent) for all purposes whatsoever, and
              neither the Company nor the Rights Agent, subject to the
              penultimate sentence of Section 7(e), shall be required to be
              affected by any notice to the contrary; and

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

     17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. No holder, as such,
of any Rights Certificate shall be entitled to vote, receive dividends or be
deemed for any purpose the holder of the number of one one-thousandths of a
share of Preferred Stock or any other securities of the Company that may at any
time be issuable on the exercise of the Rights represented thereby, nor shall
anything contained herein or in any Rights Certificate be construed to confer
upon the holder of any Rights Certificate, as such, any of the rights of a
stockholder of the Company or any right to vote for the election

                                      -22-


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), or to receive dividends or subscription rights, or otherwise,
until the Right or Rights evidenced by such Rights Certificate shall have been
exercised in accordance with the provisions.

     18. CONCERNING THE RIGHTS AGENT.

          (a) The Company agrees to pay to the Rights Agent reasonable
     compensation for all services rendered by it hereunder and, from time to
     time, on demand of the Rights Agent, its reasonable expenses and counsel
     fees and disbursements and other disbursements incurred in the preparation,
     delivery, amendment, administration and execution of this Agreement and the
     exercise and performance of its duties hereunder. The Company also agrees
     to indemnify the Rights Agent for, and to hold it harmless against, any
     loss, liability, damage, judgment, fine, penalty, claim, demand,
     settlement, cost or expense (including, without limitation, the reasonable
     fees and expenses of legal counsel), incurred without gross negligence or
     bad faith on the part of the Rights Agent (which gross negligence or bad
     faith must be determined by a final, non-appealable order, judgment, decree
     or ruling of a court of competent jurisdiction), for any action taken,
     suffered or omitted by the Rights Agent in connection with the acceptance,
     administration, exercise and performance of its duties under this
     Agreement. The costs and expenses incurred in enforcing this right of
     indemnification shall be paid by the Company. The provisions of this
     Section 18 and Section 20 below shall survive the termination of this
     Agreement, the exercise or expiration of the Rights and the resignation or
     removal of the Rights Agent.

          (b) 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
     and the exercise and performance of its duties hereunder, in reliance upon
     any Rights Certificate or certificate for the Preferred Stock or Common
     Stock 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.

     19. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.

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

                                      -23-


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

     20. DUTIES OF RIGHTS AGENT. The Rights Agent undertakes to perform only the
duties and obligations expressly imposed by this Agreement (and no implied
duties) upon the following terms and conditions, by all of which the Company and
the holders of Rights Certificates, by their acceptance thereof, shall be bound:

          (a) The Rights Agent may consult with legal counsel (who may be legal
     counsel for the Company or an employee of the Rights Agent), 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
     and 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
     (including without limitation, the identity of an Acquiring Person and the
     determination of the current per share market price of any security) 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 President, any Vice President, the
     Treasurer, any Assistant Treasurer, the Secretary or any Assistant
     Secretary of the Company and delivered to the Rights Agent; and such
     certificate 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 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 or bad faith (as determined
     by a final, non-appealable order, judgment, decree or ruling of a court of
     competent jurisdiction). Anything to the contrary notwithstanding, in no
     event shall the Rights Agent be liable for special, punitive, indirect,
     consequential or incidental loss or damage of any kind whatsoever
     (including but not limited to lost profits), even if the Rights Agent has
     been advised of the likelihood of such loss or damage. Any liability of the
     Rights Agent under this Rights Agreement will be limited to the amount of
     fees paid by the Company to the Rights Agent.

          (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
     Rights Certificates or be required to verify the same (except as to its
     countersignature on such Rights Certificates), 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 have any liability for, nor be under
     any responsibility in respect of the validity of this Agreement or the
     execution and delivery hereof (except the due execution hereof by the
     Rights Agent) or in respect of the validity or execution of any Rights
     Certificate (except its countersignature thereof); nor shall it be liable
     or responsible for any breach by the Company of any covenant or condition
     contained in this Agreement or in any Rights Certificate; nor shall it be
     liable or responsible for any adjustment required under the provisions of
     Section 11, 13 or 24 or responsible for the manner, method or amount of any
     such adjustment or the

                                      -24-


     ascertaining of the existence of facts that would require any such
     adjustment (except with respect to the exercise of Rights evidenced by
     Rights Certificates after receipt of a certificate describing any such
     adjustment, delivered pursuant to Section 12); nor shall it by any act
     hereunder be deemed to make any representation or warranty as to the
     authorization or reservation of any shares of Common Stock or Preferred
     Stock to be issued pursuant to this Agreement or any Rights Certificate or
     as to whether any shares of Common Stock or Preferred Stock will, when so
     issued, be validly authorized and issued, fully paid and nonassessable.

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

          (g) The Rights Agent is hereby authorized and directed to accept
     instructions with respect to the performance of its duties hereunder from
     any one of the Chairman of the Board, the President, any Vice President,
     the Secretary, any Assistant Secretary, the Treasurer or any Assistant
     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 or in respect of 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. The Rights Agent
     shall be fully authorized and protected in relying upon the most recent
     instructions received by any such officer. 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,
     suffered or omitted by the Rights Agent under this Rights Agreement and the
     date on and/or after which such action shall be taken or suffered or such
     omission shall be effective. The Rights Agent shall not be liable for any
     action taken or suffered by, or omission of, the Rights Agent in accordance
     with a proposal included in any such application on or after the date
     specified in such application (which date shall not be less than five
     Business Days after the date any officer of the Company actually receives
     such application, unless any such officer shall have consented in writing
     to an earlier date) unless, prior to taking any such action (or the
     effective date in the case of an omission), the Rights Agent shall have
     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
     the Rights Agent were not Rights Agent under this Agreement. Nothing herein
     shall preclude the Rights Agent or any such stockholder, affiliate,
     director, officer or employee from acting in any other capacity for the
     Company or for any other Person.

          (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
     (through its directors, officers and employees) 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 or any other Person
     resulting from any such act, default, neglect or misconduct, absent gross
     negligence or bad faith in the selection and continued employment thereof
     (each as determined by a final, non-appealable order, judgment, decree or
     ruling of a court of competent jurisdiction).

          (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

                                      -25-


     in the exercise of its rights if 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 Rights Certificate surrendered to the
     Rights Agent for exercise or transfer, the certificate attached to the form
     of assignment or form of election to purchase, as the case may be, has not
     been properly completed, the Company and the Rights Agent will deem the
     beneficial owner of the rights evidenced by such Rights Certificate to be
     an Acquiring Person or an Affiliate or Associate thereof and such
     assignment or election to purchase will not be honored.

     21. CHANGE OF RIGHTS AGENT. The Rights Agent or any successor Rights Agent
may resign and be discharged from its duties under this Agreement upon thirty
days' notice in writing mailed to the Company, and to each transfer agent of the
Common Stock and Preferred Stock, by registered or certified mail. The Company
may remove the Rights Agent or any successor Rights Agent upon thirty days'
notice in writing, mailed to the Rights Agent or successor Rights Agent, as the
case may be, and to each transfer agent of the Common Stock and Preferred Stock,
by registered or certified mail, and to the holders of the Rights 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 thirty 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 Rights Certificate (who shall,
with such notice, submit his Rights Certificate for inspection by the Company),
then any registered holder of any Rights Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be (a)
a Person organized and doing business under the laws of the United States (or of
any state of the United States) in good standing, which is authorized under such
laws to exercise corporate trust or shareholder services and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50,000,000 or (b) an Affiliate of a Person described in clause (a) of
this sentence. After appointment, the successor Rights Agent shall be vested
with the same powers, rights, duties and responsibilities as if it had been
originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock and the Preferred Stock, and mail a notice thereof in writing
to the registered holders of the Rights 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.

     22. ISSUANCE OF NEW RIGHTS CERTIFICATES. Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary, the Company may,
at its option, issue new Rights Certificates evidencing Rights in such form as
may be approved by the Board 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 Rights Certificates made in accordance with the provisions
of this Agreement.

     23. REDEMPTION.

          (a) The Board may, at its option, at any time prior to the earlier of
     (i) the Close of Business on the tenth Business Day (or such later date as
     may be determined by the Board pursuant to clause (i) of the first sentence
     of Section 3(a) with respect to the Distribution Date) following the Stock
     Acquisition Date (or, if the Stock Acquisition Date shall have occurred
     prior to the Record Date, the Close of Business on the tenth Business Day
     following the Record Date) and (ii) the Final Expiration Date, redeem all
     but not less than all the then outstanding Rights at a redemption price of

                                      -26-


     $0.001 per Right, as such amount may be appropriately adjusted to reflect
     any stock split, stock dividend or similar transaction occurring after the
     date hereof (such redemption price being hereinafter referred to as the
     "Redemption Price"). The redemption of the Rights by the Board may be made
     effective at such time, on such basis and with such conditions as the Board
     in its sole discretion may establish. The Company may, at its option, pay
     the Redemption Price in cash, shares of Common Stock (based on the "current
     market price," as defined in Section 11(d)(i), of the Common Stock at the
     time of redemption) or any other form of consideration, or any combination
     of any of the foregoing, deemed appropriate by the Board. Notwithstanding
     anything contained in this Agreement to the contrary, the Rights shall not
     be exercisable after the first occurrence of a Section 11(a)(ii) Event
     until such time as the Company's right of redemption hereunder has expired.

          (b) Immediately upon the action of the Board ordering the redemption
     of the Rights, evidence of which shall have been filed with the Rights
     Agent and without any further action and without any notice, the right to
     exercise the Rights shall terminate and the only right thereafter of the
     holders of Rights shall be to receive the Redemption Price for each Right
     so held. Promptly after the action of the Board ordering the redemption of
     the Rights, the Company shall give notice of such redemption to the Rights
     Agent and the holders of the then outstanding Rights by mailing such notice
     to all such holders at each holder's last address as it appears 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 Stock. 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.

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

     24. EXCHANGE.

          (a) The Board may, at its option, at any time after a Section
     11(a)(ii) Event, exchange all or part of the then outstanding and
     exercisable Rights (which (i) shall not include Rights that have become
     null and void pursuant to the provisions of Section 7(e), and (ii) shall
     include any Rights issued after the Distribution Date) for shares of Common
     Stock at an exchange ratio of one share of Common Stock 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 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 Stock 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 shares of Common Stock then
     outstanding.

          (b) Immediately upon the action of the Board ordering the exchange of
     any Rights pursuant to subsection (a) of this Section 24, evidence of which
     shall have been filed with the Rights Agent, and without any further action
     and without any notice, the right to exercise such Rights shall terminate
     and the only right thereafter of a holder of such Rights shall be to
     receive that number of shares of Common Stock equal to the number of such
     Rights held by such holder multiplied by the

                                      -27-

     Exchange Ratio. The Company shall promptly give public notice of any
     such exchange; provided, however, that the failure to give, or any defect
     in, such notice shall not affect the validity of such exchange. The Company
     promptly shall mail a notice of any such exchange to the Rights Agent and
     to all of the holders of such Rights at their last addresses as they appear
     upon the registry books of the Rights Agent. Any notice 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 shall state the method by
     which the exchange of shares of Common Stock for Rights will be effected
     and, in the event of any partial exchange, the number of Rights that will
     be exchanged. Any partial exchange shall be effected pro rata based on the
     number of Rights (other than Rights that have become null and void pursuant
     to the provisions of Section 7(e)) held by each holder of Rights.

          (c) In any exchange pursuant to this Section 24, the Company, at its
     option, may substitute Preferred Stock (or equivalent preferred stock, as
     such term is defined in Section 11(b)) for shares of Common Stock
     exchangeable for Rights, at the initial rate of one one-thousandth of a
     share of Preferred Stock (or equivalent preferred stock) for each share of
     Common Stock, as appropriately adjusted to reflect adjustments in the
     voting rights of the Preferred Stock pursuant to Section 3(A) of the
     Certificate of Designations attached hereto as EXHIBIT A, so that the
     fraction of a share of Preferred Stock (or equivalent preferred stock)
     delivered in lieu of each share of Common Stock shall have the same voting
     rights as one share of Common Stock.

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

          (e) The Company shall not be required to issue fractions of shares of
     Common Stock or to distribute certificates that evidence fractional shares
     of Common Stock. In lieu of such fractional shares of Common Stock, there
     shall be paid to the registered holders of the Right Certificates with
     regard to which such fractional shares of Common Stock would otherwise be
     issuable, an amount in cash equal to the same fraction of the current
     market value of a whole share of Common Stock. For the purposes of this
     subsection (e), the current market value of a whole share of Common Stock
     shall be the closing price per share of Common Stock (as determined
     pursuant to the second sentence of Section 11(d)(i)) for the Trading Day
     immediately prior to the date of exchange pursuant to this Section 24.

     25. NOTICE OF CERTAIN EVENTS.

     (a) In case the Company shall propose, at any time after the Distribution
Date,

          (i)   to pay any dividend payable in stock of any class to the holders
                of Preferred Stock or to make any other distribution to the
                holders of Preferred Stock (other than a regular quarterly cash
                dividend out of earnings or retained earnings of the Company),
                or

          (ii)  to offer to the holders of Preferred Stock rights or warrants to
                subscribe for or to purchase any additional shares of Preferred
                Stock or shares of stock of any class or any other securities,
                rights or options, or

          (iii) to effect any reclassification of its Preferred Stock (other
                than a reclassification involving only the subdivision of
                outstanding shares of Preferred Stock), or

                                      -28-

          (iv)  to effect any consolidation or merger into or with any other
                Person (other than a Subsidiary of the Company in a transaction
                that complies with Section 11(o)), or to effect any sale or
                other transfer (or to permit one or more of its Subsidiaries to
                effect any sale or other transfer), in one transaction or a
                series of related transactions, of more than 50% of the assets
                or earning power of the Company and its Subsidiaries (taken as a
                whole) to any other Person or Persons (other than the Company
                and/or any of its Subsidiaries in one or more transactions each
                of which complies with Section 11(o)), or

          (v)   to effect the liquidation, dissolution or winding up of the
                Company, then, in each such case, the Company shall give to each
                holder of a Rights Certificate, to the extent feasible and in
                accordance with Section 26, a notice of such proposed action,
                which shall specify the record date for the purposes of such
                stock dividend, distribution of rights or warrants, or the date
                on which such reclassification, consolidation, merger, sale,
                transfer, liquidation, dissolution, or winding up is to take
                place and the date of participation therein by the holders of
                the shares of Preferred Stock, if any such date is to be fixed,
                and such notice shall be so given in the case of any action
                covered by clause (i) or (ii) above at least twenty days prior
                to the record date for determining holders of the shares of
                Preferred Stock for purposes of such action, and in the case of
                any such other action, at least twenty days prior to the date of
                the taking of such proposed action or the date of participation
                therein by the holders of the shares of Preferred Stock,
                whichever shall be the earlier.

          (b) In case a Section 11(a)(ii) Event shall occur, then, in any such
     case, (i) the Company shall as soon as practicable thereafter give to each
     holder of a Rights Certificate, to the extent feasible and in accordance
     with Section 26, a notice of the occurrence of such event, which shall
     specify the event and the consequences of the event to holders of Rights
     under Section 11(a)(ii), and (ii) all references in the preceding paragraph
     to Preferred Stock shall be deemed thereafter to refer also to Common Stock
     and/or, if appropriate, other securities; provided that the failure to give
     such notice shall not affect the validity of such consent.


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

     Notices or demands authorized by this Agreement to be given or made by the

     representing shares of Common Stock) shall be sufficiently given or made
     if sent by first-class mail, postage prepaid, addressed to such holder at

     27. SUPPLEMENTS AND AMENDMENTS. Except as provided in the penultimate
sentence of this Section 27, for so long as the Rights are then redeemable, the
Company may, in its sole and absolute discretion, and the Rights Agent shall, if
the Company so directs, supplement or amend any provision of this Agreement in
any respect without the approval of any holders of the Rights. At any time when
the Rights are no longer redeemable, except as provided in the penultimate
sentence of this Section 27, the Company may, by approval of at a majority of
the members of the Board, and the Rights Agent shall, if the Company so directs,
supplement or amend this Agreement without the approval of any holders of Rights
in order (i) to cure any ambiguity or (ii) to correct or supplement any
provision contained herein that may be defective or inconsistent with any other
provisions herein, provided that no such supplement or amendment shall adversely
affect the interests of the holders of Rights as such (other than an Acquiring
Person or an Affiliate or Associate of an Acquiring Person). Upon the delivery
of a certificate from an appropriate officer of the Company that states that the
proposed supplement or amendment is in compliance with the terms of this Section
27, and provided such supplement or amendment does not change or increase the
Rights Agent's rights, duties, liabilities or obligations hereunder, the Rights
Agent shall execute such supplement or amendment. Notwithstanding anything
contained in this Agreement to the contrary, no supplement or amendment shall be
made that changes the Redemption Price. Prior to the Distribution Date, the
interests of the holders of Rights shall be deemed coincident with the interests
of the holders of Common Stock.

     28. SUCCESSORS. All the covenants and provisions of this Agreement by or

                                     FORM OF
                           CERTIFICATE OF DESIGNATIONS
                                       OF
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                                       OF
                               CENTENE CORPORATION

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

      CENTENE CORPORATION, a corporation organized and existing under the laws
of the State of Delaware (hereinafter called the "Corporation"), hereby
certifies that the following resolution was adopted by the Board of Directors of
the Corporation at a meeting duly called and held on August 26, 2002:

      RESOLVED: That pursuant to the authority granted to and vested in the
Board of Directors of the Corporation (hereinafter called the "Board") in
accordance with the provisions of the Certificate of Incorporation, as amended,
the Board hereby creates a series of Preferred Stock, $0.001 par value per share
(the "Preferred Stock"), of the Corporation and hereby states the designation
and number of shares, and fixes the relative rights, preferences and limitations
thereof as follows:

     SERIES A JUNIOR PARTICIPATING PREFERRED STOCK:

     1.   DESIGNATION AND AMOUNT. The shares of such series shall be designated
as "Series A Junior Participating Preferred Stock" (the "Series A Preferred
Stock") and the number of shares constituting the Series A Preferred Stock shall
be 40,000. Such number of shares may be increased or decreased by resolution of
the Board prior to issuance; provided, that no decrease shall reduce the number
of shares of Series A Preferred Stock to a number less than the number of shares
then outstanding plus the number of shares reserved for issuance upon the
exercise of outstanding options, rights or warrants or upon the conversion of
any outstanding securities issued by the Corporation convertible into Series A
Preferred Stock.

     2.   DIVIDENDS AND DISTRIBUTIONS.

          (A) Subject to the rights of the holders of any shares of any series
     of Preferred Stock (or any similar stock) ranking prior and superior to the
     Series A Preferred Stock with respect to dividends, the holders of shares
     of Series A Preferred Stock, in preference to the holders of Common Stock,
     $0.001 par value per share (the "Common Stock"), of the Corporation, and of
     any other junior stock, shall be entitled to receive, when, as and if
     declared by the Board out of funds of the Corporation legally available for
     the payment of dividends, quarterly dividends payable in cash on the last
     day of each fiscal quarter of the Corporation in each year (each such date
     being referred to herein as a "Quarterly Dividend Payment Date"),
     commencing on the first Quarterly Dividend Payment Date after the first
     issuance of a share or fraction of a share of Series A Preferred Stock, in
     an amount per share (rounded to the nearest cent) equal to the greater of
     (a) $10 or (b) subject to the provision for adjustment hereinafter set
     forth, 1000 times the aggregate per share amount of all cash dividends, and
     1000 times the aggregate per share amount (payable in kind) of all non-cash
     dividends or other distributions, other than a dividend payable in shares
     of Common Stock or a subdivision of the outstanding shares of Common Stock
     (by reclassification or otherwise), declared on the Common Stock since the
     immediately preceding Quarterly Dividend Payment Date or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Series A Preferred Stock. In the event the
     Corporation shall at any time declare or pay any dividend on the Common
     Stock payable in shares of

                                      A-1

     Common Stock, or effect a subdivision, combination or consolidation of
     the outstanding shares of Common Stock (by reclassification or otherwise
     than by payment of a dividend in shares of Common Stock) into a greater or
     lesser number of shares of Common Stock, then in each such case the amount
     to which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event under clause (b) of the preceding sentence
     shall be adjusted by multiplying such amount by a fraction, the numerator
     of which is the number of shares of Common Stock outstanding immediately
     after such event and the denominator of which is the number of shares of
     Common Stock that were outstanding immediately prior to such event. In the
     event the Corporation shall at any time declare or pay any dividend on the
     Series A Preferred Stock payable in shares of Series A Preferred Stock, or
     effect a subdivision, combination or consolidation of the outstanding
     shares of Series A Preferred Stock (by reclassification or otherwise than
     by payment of a dividend in shares of Series A Preferred Stock) into a
     greater or lesser number of shares of Series A Preferred Stock, then in
     each such case the amount to which holders of shares of Series A Preferred
     Stock were entitled immediately prior to such event under clause (b) of the
     first sentence of this Section 2(A) shall be adjusted by multiplying such
     amount by a fraction, the numerator of which is the number of shares of
     Series A Preferred Stock that were outstanding immediately prior to such
     event and the denominator of which is the number of shares of Series A
     Preferred Stock outstanding immediately after such event.

          (B) The Corporation shall declare a dividend or distribution on the
     Series A Preferred Stock as provided in paragraph (A) of this Section
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock) and the
     Corporation shall pay such dividend or distribution on the Series A
     Preferred Stock before the dividend or distribution declared on the Common
     Stock is paid or set apart; provided that, in the event no dividend or
     distribution shall have been declared on the Common Stock during the period
     between any Quarterly Dividend Payment Date and the next subsequent
     Quarterly Dividend Payment Date, a dividend of $10 per share on the Series
     A Preferred Stock shall nevertheless be payable on such subsequent
     Quarterly Dividend Payment Date.

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

     3.   VOTING RIGHTS. The holders of shares of Series A Preferred Stock shall
have the following voting rights:

          (A) Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Preferred Stock shall entitle the holder thereof to
     1000 votes on all matters submitted to a vote of the stockholders of the
     Corporation. In the event the Corporation shall at any time declare or pay
     any dividend on the Common Stock payable in shares of Common Stock, or
     effect a subdivision, combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common Stock) into a greater or lesser

                                      A-2

     number of shares of Common Stock, then in each such case the number of
     votes per share to which holders of shares of Series A Preferred Stock were
     entitled immediately prior to such event shall be adjusted by multiplying
     such number by a fraction, the numerator of which is the number of shares
     of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event. In the event the Corporation
     shall at any time declare or pay any dividend on the Series A Preferred
     Stock payable in shares of Series A Preferred Stock, or effect a
     subdivision, combination or consolidation of the outstanding shares of
     Series A Preferred Stock (by reclassification or otherwise than by payment
     of a dividend in shares of Series A Preferred Stock) into a greater or
     lesser number of shares of Series A Preferred Stock, then in each such case
     the number of votes per share to which holders of shares of Series A
     Preferred Stock were entitled immediately prior to such event shall be
     adjusted by multiplying such amount by a fraction, the numerator of which
     is the number of shares of Series A Preferred Stock that were outstanding
     immediately prior to such event and the denominator of which is the number
     of shares of Series A Preferred Stock outstanding immediately after such
     event.

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

          (C)  In addition:

               (i) If at any time dividends on any Series A Preferred Stock
          shall be in arrears in an amount equal to six quarterly dividends
          thereon, the holders of the Series A Preferred Stock, voting as a
          separate series from all other series of Preferred Stock and classes
          of capital stock, shall be entitled to elect two members of the Board
          in addition to any Directors elected by any other series, class or
          classes of securities and the authorized number of Directors will
          automatically be increased by two. Promptly thereafter, the Board
          shall, as soon as may be practicable, call a special meeting of
          holders of Series A Preferred Stock for the purpose of electing such
          members of the Board. Such special meeting shall in any event be held
          within 45 days of the occurrence of such arrearage.

               (ii) During any period when the holders of Series A Preferred
          Stock, voting as a separate series, shall be entitled and shall have
          exercised their right to elect two Directors, then, and during such
          time as such right continues, (a) the then authorized number of
          Directors shall be increased by two, and the holders of Series A
          Preferred Stock, voting as a separate series, shall be entitled to
          elect the additional Directors so provided for, and (b) each such
          additional Director shall not be a member of any existing class of the
          Board, but shall serve until the next annual meeting of stockholders
          for the election of Directors, or until his successor shall be elected
          and shall qualify, or until his right to hold such office terminates
          pursuant to the provisions of this Section 3(C).

               (iii) A Director elected pursuant to the terms hereof may be
          removed with or without cause by the holders of Series A Preferred
          Stock entitled to vote in an election of such Director.

               (iv) If, during any interval between annual meetings of
          stockholders for the election of Directors and while the holders of
          Series A Preferred Stock shall be entitled to elect two Directors,
          there is no such Director in office by reason of resignation, death or
          removal, then, promptly thereafter, the Board shall call a special
          meeting of the holders of Series A Preferred Stock for the purpose of
          filling such vacancy and such vacancy shall be filled at such special
          meeting. Such special

                                      A-3


          meeting shall in any event be held within 45 days of the occurrence
          of such vacancy.

               (v) At such time as the arrearage is fully cured, and all
          dividends accumulated and unpaid on any shares of Series A Preferred
          Stock outstanding are paid, and, in addition thereto, at least one
          regular dividend has been paid subsequent to curing such arrearage,
          the term of office of any Director elected pursuant to this Section
          3(C), or his successor, shall automatically terminate, and the
          authorized number of Directors shall automatically decrease by two,
          the rights of the holders of the shares of the Series A Preferred
          Stock to vote as provided in this Section 3(C) shall cease, subject to
          renewal from time to time upon the same terms and conditions, and the
          holders of shares of the Series A Preferred Stock shall have only the
          limited voting rights elsewhere herein set forth.

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

     4.   CERTAIN RESTRICTIONS.

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

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

               (ii) declare or pay dividends, or make any other distributions,
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution or winding up) with the Series A
          Preferred Stock, except dividends paid ratably on the Series A
          Preferred Stock and all such parity stock on which dividends are
          payable or in arrears in proportion to the total amounts to which the
          holders of all such shares are then entitled;

               (iii) redeem or purchase or otherwise acquire for consideration
          shares of any stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Preferred
          Stock, provided that the Corporation may at any time redeem, purchase
          or otherwise acquire shares of any such junior stock in exchange for
          shares of any stock of the Corporation ranking junior (either as to
          dividends or upon dissolution, liquidation or winding up) to the
          Series A Preferred Stock; or

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

          (B) The Corporation shall not permit any subsidiary of the Corporation
     to purchase or otherwise acquire for consideration any shares of stock of
     the Corporation unless the Corporation

                                      A-4

     could, under paragraph (A) of this Section 4, purchase or otherwise acquire
     such shares at such time and in such manner.

     5.   REACQUIRED SHARES. Any shares of Series A Preferred Stock purchased or
otherwise acquired by the Corporation in any manner whatsoever shall be retired
and cancelled promptly after the acquisition thereof. All such shares shall upon
their cancellation become authorized but unissued shares of Preferred Stock and
may be reissued as part of a new series of Preferred Stock subject to the
conditions and restrictions on issuance set forth herein, in the Certificate of
Incorporation, or in any other Certificate of Designations creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

     6.   LIQUIDATION, DISSOLUTION OR WINDING UP.

          (A) Upon any liquidation, dissolution or winding up of the
     Corporation, no distribution shall be made (1) to the holders of shares of
     stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred Stock unless, prior
     thereto, the holders of shares of Series A Preferred Stock shall have
     received $1000 per share, plus an amount equal to accrued and unpaid
     dividends and distributions thereon, whether or not declared, to the date
     of such payment, provided that the holders of shares of Series A Preferred
     Stock shall be entitled to receive an aggregate amount per share, subject
     to the provision for adjustment hereinafter set forth, equal to 1000 times
     the aggregate amount to be distributed per share to holders of shares of
     Common Stock, or (2) to the holders of shares of stock ranking on a parity
     (either as to dividends or upon liquidation, dissolution or winding up)
     with the Series A Preferred Stock, except distributions made ratably on the
     Series A Preferred Stock and all such parity stock in proportion to the
     total amounts to which the holders of all such shares are entitled upon
     such liquidation, dissolution or winding up.

          (B) Neither the consolidation, merger or other business combination of
     the Corporation with or into any other corporation nor the sale, lease,
     exchange or conveyance of all or any part of the property, assets or
     business of the Corporation shall be deemed to be a liquidation,
     dissolution or winding up of the Corporation for purposes of this Section
     6.

          (C) In the event the Corporation shall at any time declare or pay any
     dividend on the Common Stock payable in shares of Common Stock, or effect a
     subdivision, combination or consolidation of the outstanding shares of
     Common Stock (by reclassification or otherwise than by payment of a
     dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the aggregate amount to
     which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event under the proviso in clause (1) of
     paragraph (A) of this Section 6 shall be adjusted by multiplying such
     amount by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event. In the event the Corporation shall at any
     time declare or pay any dividend on the Series A Preferred Stock payable in
     shares of Series A Preferred Stock, or effect a subdivision, combination or
     consolidation of the outstanding shares of Series A Preferred Stock (by
     reclassification or otherwise than by payment of a dividend in shares of
     Series A Preferred Stock) into a greater or lesser number of shares of
     Series A Preferred Stock, then in each such case the aggregate amount to
     which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event under the proviso in clause (1) of
     paragraph (A) of this Section 6 shall be adjusted by multiplying such
     amount by a fraction, the numerator of which is the number of shares of
     Series A Preferred Stock that were outstanding immediately prior to such
     event and the denominator of which is the number of shares of Series A
     Preferred Stock outstanding immediately after such event.

                                      A-5


     7. CONSOLIDATION, MERGER, ETC. Notwithstanding anything to the contrary
contained herein, in case the Corporation shall enter into any consolidation,
merger, combination or other transaction in which the shares of Common Stock are
exchanged for or changed into other stock or securities, cash and/or any other
property, then in any such case each share of Series A Preferred Stock shall at
the same time be similarly exchanged or changed into an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is changed or exchanged. In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision, combination or consolidation of the outstanding
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in shares of Common Stock) into a greater or lesser number of shares of
Common Stock, then in each such case the amount set forth in the preceding
sentence with respect to the exchange or change of shares of Series A Preferred
Stock shall be adjusted by multiplying such amount by a fraction, the numerator
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event. In the event the
Corporation shall at any time declare or pay any dividend on the Series A
Preferred Stock payable in shares of Series A Preferred Stock, or effect a
subdivision, combination or consolidation of the outstanding shares of Series A
Preferred Stock (by reclassification or otherwise than by payment of a dividend
in shares of Series A Preferred Stock) into a greater or lesser number of shares
of Series A Preferred Stock, then in each such case the amount set forth in the
first sentence of this Section 7 with respect to the exchange or change of
shares of Series A Preferred Stock shall be adjusted by multiplying such amount
by a fraction, the numerator of which is the number of shares of Series A
Preferred Stock that were outstanding immediately prior to such event and the
denominator of which is the number of shares of Series A Preferred Stock
outstanding immediately after such event.

     8. NO REDEMPTION. The shares of Series A Preferred Stock shall not be
redeemable.

     9. RANK. The Series A Preferred Stock shall rank, with respect to the
payment of dividends and the distribution of assets, junior to all series of any
other class of the Preferred Stock issued either before or after the issuance of
the Series A Preferred Stock, unless the terms of any such series shall provide
otherwise.

     10. AMENDMENT. At such time as any shares of Series A Preferred Stock are
outstanding, the Certificate of Incorporation, as amended, of the Corporation
shall not be amended in any manner that would materially alter or change the
powers, preferences or special rights of the Series A Preferred Stock so as to
affect them adversely without the affirmative vote of the holders of at least
two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

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

      IN WITNESS WHEREOF, this Certificate of Designations is executed on behalf
of the Corporation by its Chief Executive Officer this __ day of August, 2002.

                               RIGHTS CERTIFICATE

      This certifies that ____________, or registered assigns, is the registered
owner of the number of Rights set forth above, each of which entitles the owner
thereof, subject to the terms, provisions and conditions of the Rights
Agreement, dated as of August 30, 2002 (the "Rights Agreement"), between Centene
Corporation, a Delaware corporation (the "Company"), and Mellon Investor
Services LLC, a New Jersey limited liability company, as Rights Agent (the
"Rights Agent"), to purchase from the Company after the Distribution Date (as
such term is defined in the Rights Agreement) and at any time prior to 5:00 p.m.
(St. Louis, Missouri time) on August 30, 2012 at the office of the Rights Agent
designated for such purpose, or its successors as Rights Agent, one
one-thousandth of a fully paid, non-assessable share of Series A Junior
Participating Preferred Stock (the "Preferred Stock") of the Company, $0.001 par
value per share, at a purchase price of $0.17 in cash per one one-thousandth of
a share (the "Purchase Price"), upon presentation and surrender of this Rights
Certificate with the Form of Election to Purchase and related Certificate duly
executed. The number of Rights evidenced by this Rights Certificate (and the
number of one one-thousandth of a share of Preferred Stock that may be purchased
upon exercise hereof) set forth above, and the Purchase Price set forth above,
are the number and Purchase Price as of the close of business on September 10,
2002, based on the Preferred Stock as constituted at such date. Capitalized
terms used herein and not otherwise defined herein shall have the meanings
ascribed to such terms in the Rights Agreement.

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

      As provided in the Rights Agreement, the Purchase Price and the number and
kind of shares of Preferred Stock or other securities that may be purchased upon
the exercise of the Rights evidenced by this Rights Certificate are subject to
modification and adjustment upon the happening of certain events, including
Section 11(a)(ii) Events.

      This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,

                                      B-1


limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the principal offices of the
Company and are available upon written request to the Company.

      This Rights Certificate, with or without other Rights Certificates, upon
surrender at the office of the Rights Agent designated for such purpose, with
the Form of Election and Certificate set forth on the reverse side duly
executed, may be exchanged for another Rights Certificate or Rights Certificates
of like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of one one-thousandths of a share of Preferred Stock as the
Rights evidenced by the Rights Certificate or Rights Certificates surrendered
shall have entitled such holder to purchase. If this Rights Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender hereof
another Rights Certificate or Rights Certificates for the number of whole Rights
not exercised.

      Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Certificate may be redeemed by the Company at its option at a redemption
price of $0.001 per Right at any time prior to the earlier of (i) the close of
business on the tenth Business Day (or such later date as may be determined by
the Board pursuant to clause (i) of the first sentence of Section 3(a) with
respect to the Distribution Date) following the Stock Acquisition Date (or, if
the Stock Acquisition Date shall have occurred prior to the Record Date, the
close of business on the tenth Business Day following the Record Date) and (ii)
the Final Expiration Date.

      Subject to the provisions of the Rights Agreement, the Company may, at its
option, at any time after a Section 11(a)(ii) Event, exchange all or part of the
Rights evidenced by this Certificate for shares of the Company's Common Stock or
for Preferred Stock (or shares of a class or series of the Company's preferred
stock having the same rights, privileges and preferences as the Preferred
Stock).

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

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

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

EXHIBIT C


                              SUMMARY OF RIGHTS TO
                            PURCHASE PREFERRED STOCK

      On August 30, 2002, the Board of Directors of Centene Corporation (the
"Company"), declared a dividend of one Right for each outstanding share of the
Company's Common Stock, $0.001 par value per share (the "Common Stock"), to
stockholders of record at the close of business on September 10, 2002 (the
"Record Date"). Each "Right" entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series A Junior Participating Preferred
Stock, $0.001 par value per share (the "Preferred Stock"), at a purchase price
of $170.00 in cash, subject to adjustment (the "Purchase Price"). The
description and terms of the Rights are set forth in a Rights Agreement dated as
of August 30, 2002 (the "Rights Agreement") between the Company and Mellon
Investor Services LLC, as Rights Agent.

      Initially, the Rights are not exercisable and will be attached to all
certificates representing outstanding shares of Common Stock, and no separate
certificate representing the Rights (a "Rights Certificate") will be
distributed. The Rights will separate from the Common Stock, and the
distribution date will occur, upon the earlier of (i) 10 business days following
the first date of a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 15% or more of the outstanding shares of
Common Stock or (ii) 10 business days following the commencement of a tender
offer or exchange offer that would result in a person or group beneficially
owning 15% or more of the outstanding shares of Common Stock (the "Distribution
Date"). The Distribution Date may be deferred in circumstances determined by the
Board of Directors. In addition, certain inadvertent acquisitions will not
trigger the occurrence of the Distribution Date. Until the Distribution Date (or
earlier redemption or expiration of the Rights), (i) the Rights will be
evidenced by the Common Stock certificates outstanding on the Record Date,
together with this Summary of Rights, or by new Common Stock certificates issued
after the Record Date that contain a notation incorporating the Rights Agreement
by reference, (ii) the Rights will be transferred with and only with such Common
Stock certificates; and (iii) the surrender for transfer of any certificates for
Common Stock outstanding (with or without a copy of this Summary of Rights or
such notation) will also constitute the transfer of the Rights associated with
the Common Stock represented by such certificate.

      The Rights are not exercisable until the Distribution Date and will expire
upon the close of business on August 30, 2012 (the "Final Expiration Date")
unless earlier redeemed or exchanged as described below. As soon as practicable
after the Distribution Date, separate Rights Certificates will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date and, thereafter, the separate Rights Certificates alone will
represent the Rights. Except as otherwise determined by the Board of Directors,
and except for shares of Common Stock issued upon exercise, conversion or
exchange of then outstanding options, convertible or exchangeable securities or
other contingent obligations to issue shares or pursuant to any employee benefit
plan or arrangement, only shares of Common Stock issued prior to the
Distribution Date will be issued with Rights.

      In the event that any person becomes an Acquiring Person, then, promptly
following the first occurrence of such event, each holder of a Right (except as
provided below and in Section 7(e) of the Rights Agreement) shall thereafter
have the right to receive, upon exercise, that number of shares of Common Stock
of the Company (or, in certain circumstances, cash, property or other securities
of the Company) that equals the exercise price of the Right divided by 50% of
the current market price (as defined in the Rights Agreement) per share of
Common Stock at the date of the occurrence of such event. However, Rights are
not exercisable following such event until such time as the Rights are no longer
redeemable by the Company as described below. Notwithstanding any of the
foregoing, following the occurrence of such event, all Rights that are, or,
under certain circumstances specified in the Rights Agreement, were,
beneficially owned by any Acquiring Person will be null and void. The event
summarized in this paragraph is referred to as a "Section 11(a)(ii) Event."

                                      C-1


      For example, at an exercise price of $60 per Right, each Right not owned
by an Acquiring Person (or by certain related parties) following a Section
11(a)(ii) Event would entitle its holder to purchase for $60 such number of
shares of Common Stock (or other consideration, as noted above) as equals $60
divided by one-half of the current market price (as defined in the Rights
Agreement) of the Common Stock. Assuming that the Common Stock had a market
price of $30 per share at such time, the holder of each valid Right would be
entitled to purchase four shares of Common Stock, having a market value of 4 x
$30 or $120 for $60.

      In the event that, at any time after any person becomes an Acquiring
Person, (i) the Company is consolidated with, or merged with and into, another
entity and the Company is not the surviving entity of such consolidation or
merger or if the Company is the surviving entity, but shares of its outstanding
Common Stock are changed or exchanged for stock or securities (of any other
person) or cash or any other property, or (ii) more than 50% of the Company's
assets or earning power is sold or transferred, each holder of a Right (except
Rights that previously have been voided as set forth above) shall thereafter
have the right to receive, upon exercise, that number of shares of common stock
of the acquiring company that equals the exercise price of the Right divided by
50% of the current market price (as defined in the Rights Agreement) of such
common stock at the date of the occurrence of the event. The events summarized
in this paragraph are referred to as "Section 13 Events." A Section 11(a)(ii)
Event and Section 13 Events are collectively referred to as "Triggering Events."

      For example, at an exercise price of $60 per Right, each valid Right
following a Section 13 Event would entitle its holder to purchase for $60 such
number of shares of common stock of the acquiring company as equals $60 divided
by one-half of the current market price (as defined in the Rights Agreement) of
such common stock. Assuming that such common stock had a market price of $30 per
share at such time, the holder of each valid Right would be entitled to purchase
four shares of common stock of the acquiring company, having a market value of 4
x $30 or $120 for $60.

      At any time after the occurrence of a Section 11(a)(ii) Event, when no
person owns a majority of the Common Stock, the Board of Directors may exchange
the Rights (other than Rights owned by such Acquiring Person that have become
null and void), in whole or in part, at an exchange ratio of one share of Common
Stock, or one one-thousandth of a share of Preferred Stock (or of a share of a
class or series of the Company's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

      The Purchase Price payable, and the number of units of Preferred Stock or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock, (ii) if holders of the Preferred Stock are granted certain rights or
warrants to subscribe for Preferred Stock or convertible securities at less than
the then-current market price (as defined in the Rights Agreement) of the
Preferred Stock, or (iii) upon the distribution to holders of the Preferred
Stock of evidences of indebtedness or assets (excluding regular periodic cash
dividends paid out of earnings or retained earnings) or of subscription rights
or warrants (other than those referred to above). The number of Rights
associated with each share of Common Stock is also subject to adjustment in the
event of a stock split of the Common Stock or a stock dividend on the Common
Stock payable in Common Stock or subdivisions, consolidations or combinations of
the Common Stock 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 amount to at least 1% of the Purchase
Price. No fractional shares of Preferred Stock (other than fractions that are
integral multiples of one one-thousandth of a share of Preferred Stock) will be
issued and, in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Stock on the last trading date prior to the date
of exercise.

                                      C-2


      Preferred Stock purchasable upon exercise of the Rights will not be
redeemable. Each share of Preferred Stock will be entitled to receive, when, as
and if declared by the Board of Directors, a minimum preferential quarterly
dividend payment of $10 per share or, if greater, an aggregate dividend of 1000
times the dividend declared per share of Common Stock. In the event of
liquidation, the holders of the Preferred Stock will be entitled to a minimum
preferential liquidation payment of $1000 per share, plus an amount equal to
accrued and unpaid dividends, and will be entitled to an aggregate payment of
1000 times the payment made per share of Common Stock. Each share of Preferred
Stock will have 1000 votes, voting together with the Common Stock. In the event
of any merger, consolidation or other transaction in which Common Stock is
changed or exchanged, each share of Preferred Stock will be entitled to receive
1000 times the amount received per share of Common Stock. These rights are
protected by customary antidilution provisions. Because of the nature of the
Preferred Stock's dividend, liquidation and voting rights, the value of one
one-thousandth of a share of Preferred Stock purchasable upon exercise of each
Right should approximate the value of one share of Common Stock.

      At any time prior to the earlier of the tenth Business Day (or such later
date as may be determined by the Board of Directors) after the Stock Acquisition
Date, the Company may redeem the Rights in whole, but not in part, at a price of
$0.001 per Right (the "Redemption Price"), payable in cash or stock. Immediately
upon the redemption of the Rights or such earlier time as established by the
Board of Directors in the resolution ordering the redemption of the Rights, the
Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price. The Rights may also be redeemable following
certain other circumstances specified in the Rights Agreement.

      Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including the right to vote or to
receive dividends. Although the distribution of the Rights should not be taxable
to stockholders or to the Company, stockholders may, depending upon the
circumstances, recognize taxable income in the event that the Rights become
exercisable for Common Stock (or other consideration) of the Company or for
common stock of the acquiring company as set forth above.

      Any provision of the Rights Agreement, other than the redemption price,
may be amended by the Board of Directors prior to such time as the Rights are no
longer redeemable. Once the Rights are no longer redeemable, the Board of
Directors' authority to amend the Rights is limited to correcting ambiguities or
defective or inconsistent provisions in a manner that does not adversely affect
the interest of holders of Rights.

      The Rights are intended to protect the stockholders of the Company in the
event of an unfair or coercive offer to acquire the Company and to provide the
Board of Directors with adequate time to evaluate unsolicited offers. The Rights
may have anti-takeover effects. The Rights will cause substantial dilution to a
person or group that attempts to acquire the Company without conditioning the
offer on a substantial number of Rights being acquired. The Rights, however,
should not affect any prospective offeror willing to make an offer at a fair
price and otherwise in the best interests of the Company and its stockholders,
as determined by a majority of the Board of Directors. The Rights should not
interfere with any merger or other business combination approved by the Board of
Directors.

Exchange Commission as an Exhibit to the Company's Current Report on Form 8-K
dated August 30, 2002. A copy of the Rights Agreement is available free of
charge from the Company. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
