                              AMENDED AND RESTATED
                        PREFERRED SHARE RIGHTS AGREEMENT

         This Amended and Restated Preferred Share Rights Agreement is made as
of January 1, 2005, by and between Cholestech Corporation, a California
corporation, and Computershare Investor Services, LLC.

         WHEREAS, the Company and ChaseMellon Shareholder Services, L.L.C. are
parties to that certain Rights Agreement dated as of January 22, 1997 (the
"Prior Agreement");

         WHEREAS, the Board of Directors of the Company has determined that it
is in the best interests of the Company and its shareholders to amend and
restate the Prior Agreement as set forth herein to reflect Computershare
Investor Services, LLC as the Rights Agent, and the Rights Agent has agreed to
the amendment and restatement of the Prior Agreement as set forth herein;

         WHEREAS, the Company has determined that, pursuant to Section 27 of the
Prior Agreement, the Prior Agreement may be amended and restated as set forth
herein without the approval of the holders of the Rights (as hereinafter
defined).

         On January 22, 1997 (the "Rights Dividend Declaration Date"), the Board
of Directors of the Company authorized and declared a dividend of one Preferred
Share Purchase Right (a "Right") for each Common Share (as hereinafter defined)
of the Company outstanding as of the Close of Business (as hereinafter defined)
on March 31, 1997 (the "Record Date"), each Right representing the right to
purchase one one-thousandth (0.001) of a share of Series A Participating
Preferred Stock (as such number may be adjusted pursuant to the provisions of
this Agreement), having the rights, preferences and privileges set forth in the
form of Certificate of Determination of Rights, Preferences and Privileges of
Series A Participating Preferred Stock attached hereto as Exhibit A, upon the
terms and subject to the conditions herein set forth, and further authorized and
directed the issuance of one Right (as such number may be adjusted pursuant to
the provisions of this Agreement) with respect to each Common Share that shall
become outstanding between the Record Date and the earlier of the Distribution
Date and the Expiration Date (as such terms are hereinafter defined), and in
certain circumstances after the Distribution Date.

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

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

                  (a) "ACQUIRING PERSON" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the Common Shares then outstanding, but shall
not include the Company, any Subsidiary of the Company or any employee benefit
plan of the Company or of any Subsidiary of the Company, or any entity holding
Common Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall be deemed to be an Acquiring Person as the result of
an acquisition of Common Shares by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to 15% or more of the

<PAGE>

Common Shares of the Company then outstanding; provided, however, that if a
Person shall become the Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding by reason of share purchases by the Company and
shall, after such share purchases by the Company, become the Beneficial Owner of
any additional Common Shares of the Company (other than pursuant to a dividend
or distribution paid or made by the Company on the outstanding Common Shares in
Common Shares or pursuant to a split or subdivision of the outstanding Common
Shares), then such Person shall be deemed to be an Acquiring Person unless upon
becoming the Beneficial Owner of such additional Common Shares of the Company
such Person does not beneficially own 15% or more of the Common Shares of the
Company then outstanding. Notwithstanding the foregoing, (i) if the Company's
Board of Directors determines in good faith that a Person who would otherwise be
an "Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), has become such inadvertently (including, without limitation,
because (A) such Person was unaware that it beneficially owned a percentage of
the Common Shares that would otherwise cause such Person to be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this paragraph (a),
or (B) such Person was aware of the extent of the Common Shares it beneficially
owned but had no actual knowledge of the consequences of such beneficial
ownership under this Agreement) and without any intention of changing or
influencing control of the Company, and if such Person divested or divests as
promptly as practicable a sufficient number of Common Shares so that such Person
would no longer be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), then such Person shall not be deemed to be or
to have become an "Acquiring Person" for any purposes of this Agreement; and
(ii) if, as of the date hereof, any Person is the Beneficial Owner of 15% or
more of the Common Shares outstanding, such Person shall not be or become an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), unless and until such time as such Person shall become the
Beneficial Owner of additional Common Shares (other than pursuant to a dividend
or distribution paid or made by the Company on the outstanding Common Shares in
Common Shares or pursuant to a split or subdivision of the outstanding Common
Shares), unless, upon becoming the Beneficial Owner of such additional Common
Shares, such Person is not then the Beneficial Owner of 15% or more of the
Common Shares then outstanding.

                  (b) "ADJUSTMENT FRACTION" shall have the meaning set forth in
Section 11(a)(i) hereof.

                  (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) A Person shall be deemed the "BENEFICIAL OWNER" of and
shall be deemed to "BENEFICIALLY OWN" any securities:

                           (i) which such Person or any of such Person's
Affiliates or Associates beneficially owns, directly or indirectly, for purposes
of Section 13(d) of the Exchange Act and Rule 13d-3 thereunder (or any
comparable or successor law or regulation);

                           (ii) which such Person or any of such Person's
Affiliates or Associates has (A) the right to acquire (whether such right is
exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or understanding (other than customary agreements

                                      -2-
<PAGE>

with and between underwriters and selling group members with respect to a bona
fide public offering of securities), or upon the exercise of conversion rights,
exchange rights, rights (other than the Rights), warrants or options, or
otherwise; provided, however, that a Person shall not be deemed pursuant to this
Section 1(d)(ii)(A) to be the Beneficial Owner of, or to beneficially own, (1)
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 (2) securities
which a Person or any of such Person's Affiliates or Associates may be deemed to
have the right to acquire pursuant to any merger or other acquisition agreement
between the Company and such Person (or one or more of its Affiliates or
Associates) if such agreement has been approved by the Board of Directors of the
Company prior to there being an Acquiring Person; or (B) the right to vote
pursuant to any agreement, arrangement or understanding; provided, however, that
a Person shall not be deemed the Beneficial Owner of, or to beneficially own,
any security under this Section 1(d)(ii)(B) if the agreement, arrangement or
understanding to vote such security (1) arises solely from a revocable proxy or
consent given to such Person in response to a public proxy or consent
solicitation made pursuant to, and in accordance with, the applicable rules and
regulations of the Exchange Act and (2) is not also then reportable on Schedule
13D under the Exchange Act (or any comparable or successor report); or

                           (iii) which are beneficially owned, directly or
indirectly, by any other Person (or any Affiliate or Associate thereof) with
which such Person or any of such Person's Affiliates or Associates has any
agreement, arrangement or understanding, whether or not in writing (other than
customary agreements with and between underwriters and selling group members
with respect to a bona fide public offering of securities) for the purpose of
acquiring, holding, voting (except to the extent contemplated by the proviso to
Section 1(d)(ii)(B)) or disposing of any securities of the Company; provided,
however, that in no case shall an officer or director of the Company be deemed
(x) the Beneficial Owner of any securities beneficially owned by another officer
or director of the Company solely by reason of actions undertaken by such
persons in their capacity as officers or directors of the Company or (y) the
Beneficial Owner of securities held of record by the trustee of any employee
benefit plan of the Company or any Subsidiary of the Company for the benefit of
any employee of the Company or any Subsidiary of the Company, other than the
officer or director, by reason of any influence that such officer or director
may have over the voting of the securities held in the plan.

                  (e) "BUSINESS DAY" shall mean any day other than a Saturday,
Sunday or a day on which the New York Stock Exchange is closed.

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

                  (g) "COMMON SHARES" when used with reference to the Company
shall mean the shares of Common Stock of the Company, no par value Common Shares
when used with reference to any Person other than the Company shall mean the
capital stock (or equity interest) with the greatest voting power of such other
Person or, if such other Person is a Subsidiary of another Person, the Person or
Persons which ultimately control such first-mentioned Person.

                                      -3-
<PAGE>

                  (h) "COMMON STOCK EQUIVALENTS" shall have the meaning set
forth in Section 11(a)(iii) hereof.

                  (i) "COMPANY" shall mean Cholestech Corporation, a California
corporation, subject to the terms of Section 13(a)(iii)(C) hereof.

                  (j) "CURRENT PER SHARE MARKET PRICE" of any security (a
"Security" for purposes of this definition), for all computations other than
those made pursuant to Section 11(a)(iii) hereof, shall mean the average of the
daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days immediately prior to such date, and for purposes of computations
made pursuant to Section 11(a)(iii) hereof, the Current Per Share Market Price
of any Security on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the ten (10) consecutive Trading
Days immediately prior to such date; provided, however, that in the event that
the Current Per Share Market Price of the Security is determined during a period
following the announcement by the issuer of such Security of (i) a dividend or
distribution on such Security payable in shares of such Security or securities
convertible into such shares or (ii) any subdivision, combination or
reclassification of such Security, and prior to the expiration of the applicable
thirty (30) Trading Day or ten (10) Trading Day period, after the ex-dividend
date for such dividend or distribution, or the record date for such subdivision,
combination or reclassification, then, and in each such case, the Current Per
Share Market Price shall be appropriately adjusted to reflect the current market
price per share equivalent of such Security. The closing price for each day
shall be the last sale price, regular way, or, in case no such sale takes place
on such day, the average of the closing bid and asked prices, regular way, in
either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the Security is not listed or admitted to trading on the
New York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Security is listed or admitted to trading or,
if the Security is not listed or admitted to trading on any national securities
exchange, the last sale price or, if such last sale price is not reported, the
average of the high bid and low asked prices in the over-the-counter market, as

Security is not quoted by any such organization, the average of the closing bid
and asked prices as furnished by a professional market maker making a market in
the Security selected by the Board of Directors of the Company. If on any such
date no market maker is making a market in the Security, the fair value of such
shares on such date as determined in good faith by the Board of Directors of the
Company shall be used. If the Preferred Shares are not publicly traded, the
Current Per Share Market Price of the Preferred Shares shall be conclusively
deemed to be (x) the Current Per Share Market Price of the Common Shares as
determined pursuant to this Section 1(j), as appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof, multiplied by (y) 1,000. If the Security is not publicly held or so
listed or traded, Current Per Share Market Price shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent and shall be conclusive for all purposes.

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 Company's Board of Directors)

or of any Subsidiary of the Company, or any Person or entity 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(a) of

successful consummation thereof, such Person would be an Acquiring Person.

                  (m) "EQUIVALENT SHARES" shall mean Preferred Shares and any

Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights (in accordance with Section 14(a)
hereof). As of the Distribution Date, the Rights will be evidenced solely by
such Rights Certificates and may be transferred by the transfer of the Rights
Certificates as permitted hereby, separately and apart from any transfer of
Common Shares, and the holders of such Rights Certificates as listed in the
records of the Company or any transfer agent or registrar for the Rights shall
be the record holders thereof.

                  (b) On the Record Date or as soon as practicable thereafter,
the Company will send a copy of the Summary of Rights by first-class,
postage-prepaid mail, to each record holder of Common Shares as of the Close of
Business on the Record Date, at the address of such holder shown on the records
of the Company's transfer agent and registrar. With respect to certificates for
Common Shares outstanding as of the Record Date, until the Distribution Date,
the Rights will be evidenced by such certificates registered in the names of the
holders thereof together with the Summary of Rights.

                  (c) Unless the Board of Directors by resolution adopted at or
before the time of the issuance of any Common Shares after the Record Date but
prior to the earlier of the Distribution Date or the Expiration Date (or, in
certain circumstances provided in Section 22 hereof, after the Distribution
Date) specifies to the contrary, Rights shall be issued in respect of all Common
Shares that are so issued, and certificates representing such Common Shares
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 A RIGHTS AGREEMENT BETWEEN CHOLESTECH
         CORPORATION AND COMPUTERSHARE INVESTOR SERVICES, LLC, AS THE RIGHTS
         AGENT, DATED AS OF JANUARY 1, 2005, AS IT MAY BE AMENDED THEREAFTER
         PURSUANT TO ITS TERMS (THE "RIGHTS AGREEMENT"), THE TERMS OF WHICH ARE
         HEREBY INCORPORATED HEREIN BY REFERENCE AND A COPY OF WHICH IS ON FILE
         AT THE PRINCIPAL EXECUTIVE OFFICES OF CHOLESTECH CORPORATION UNDER
         CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, SUCH
         RIGHTS WILL BE EVIDENCED BY SEPARATE CERTIFICATES AND WILL NO LONGER BE
         EVIDENCED BY THIS CERTIFICATE. CHOLESTECH CORPORATION WILL MAIL TO THE
         HOLDER OF THIS CERTIFICATE A COPY OF THE RIGHTS AGREEMENT WITHOUT
         CHARGE AFTER RECEIPT OF A WRITTEN REQUEST THEREFOR. UNDER CERTAIN
         CIRCUMSTANCES SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS ISSUED TO, OR
         HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR 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 or (ii) the Expiration Date, the Rights
associated with the Common Shares represented by such certificates shall be
evidenced by such certificates alone, and the surrender for transfer of any such
certificate shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

                  (d) In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.

         Section 4. Form of Rights Certificates.

                  (a) The Rights Certificates (and the forms of election to
purchase Common Shares and of assignment to be printed on the reverse thereof)
shall be substantially in the form of Exhibit B hereto and may have such marks
of identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate 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 a national market system, on which
the Rights may from time to time be listed or included, or to conform to usage.
Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever distributed, shall be dated as of the Record Date (or in
the case of Rights issued with respect to Common Shares issued by the Company
after the Record Date, as of the date of issuance of such Common Shares) and on
their face shall entitle the holders thereof to purchase such number of
one-thousandths (0.001) of a Preferred Share as shall be set forth therein

                                      -8-
<PAGE>

at the price set forth therein (such exercise price per one one-thousandth
(0.001) of a Preferred Share being hereinafter referred to as the "Exercise
Price" and the aggregate Exercise Price of all Preferred Shares issuable upon
exercise of one Right being hereinafter referred to as the "Total Exercise
Price"), but the number and type of securities purchasable upon the exercise of
each Right and the Exercise Price shall be subject to adjustment as provided
herein.

                  (b) Any Rights Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring Person, (ii) a Post-Event
Transferee, (iii) a Pre-Event Transferee or (iv) any subsequent transferee
receiving transferred Rights from a Post-Event Transferee or a Pre-Event
Transferee, either directly or through one or more intermediate transferees, and
any Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon
transfer, exchange, replacement or adjustment of any other Rights Certificate
referred to in this sentence, shall contain (to the extent feasible) the
following legend:

         THE RIGHTS 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 THE RIGHTS AGREEMENT.

         Section 5. Countersignature and Registration.

                  (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board, its Chief Executive Officer, its Chief
Financial Officer, its President or any Vice President, either manually or by
facsimile signature, and by the Secretary or an Assistant Secretary of the
Company, either manually or by facsimile signature, and shall have affixed
thereto the Company's seal (if any) or a facsimile thereof. The Rights
Certificates shall be manually countersigned by the Rights Agent and shall not
be valid for any purpose unless countersigned. In case any officer of the
Company who shall have signed any of the 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 on behalf of the Company had not ceased to be such officer of the
Company; and any Rights Certificate 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, the Rights Agent will
keep or cause to be kept, at its office designated for such purposes, 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 and the date of each of the Rights Certificates.

         Section 6. Transfer, Split Up, Combination and Exchange of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

                  (a) Subject to the provisions of Sections 7(e), 14 and 24
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the Expiration Date, any Rights Certificate
or Rights Certificates may be transferred, split up, combined or exchanged for
another Rights Certificate or Rights Certificates, entitling the registered
holder to purchase a like number of one-thousandths (0.001) of a Preferred Share
(or, following a Triggering Event, other securities, cash or other assets, as
the case may be) as the Rights Certificate or Rights Certificates surrendered
then entitled such holder to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Rights Certificate or Rights
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Rights Certificate or Rights Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose. Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered 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 shall reasonably request.
Thereupon the Rights Agent shall, subject to Sections 7(e), 14 and 24 hereof,
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 from the registered holder 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.

                  (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 reasonably satisfactory to them, and, at the Company's
request, reimbursement to the Company and the Rights Agent of all reasonable
expenses incidental thereto, and upon surrender to the Rights Agent and
cancellation of the Rights Certificate if mutilated, the Company will make and
deliver a new Rights Certificate of like tenor to the Rights Agent for delivery
to the registered holder in lieu of the Rights Certificate so lost, stolen,
destroyed or mutilated.

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

                  (a) Subject to Sections 7(e), 23(b) and 24(b) hereof, the
registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein) in whole or in part at any time
after the Distribution Date and prior to the Close of Business on the Expiration
Date by surrender of the Rights Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the
office of the Rights Agent designated for such purpose, together with payment of
the Exercise Price for each one-thousandth (0.001) of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets as the case
may be) as to which the Rights are exercised.

                  (b) The Exercise Price for each one-thousandth (0.001) of a
Preferred Share issuable pursuant to the exercise of a Right shall initially be
Forty-Four Dollars and No Cents

                                      -10-
<PAGE>

($44.00), shall be subject to adjustment from time to time as provided in
Sections 11 and 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

                  (c) Upon receipt of a Rights Certificate representing
exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Exercise Price for the number of one-thousandths
(0.001) of a Preferred Share (or, following a Triggering Event, other
securities, cash or other assets as the case may be) to be purchased and an
amount equal to any applicable transfer tax required to be paid by the holder of
such Rights Certificate in accordance with Section 9(e) hereof, the Rights Agent
shall, subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition
from any transfer agent of the Preferred Shares (or make available, if the
Rights Agent is the transfer agent for the Preferred Shares) a certificate or
certificates for the number of one-thousandths (0.001) of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets as the case
may be) to be purchased and the Company hereby irrevocably authorizes its
transfer agent to comply with all such requests or (B) if the Company shall have
elected to deposit the total number of one-thousandths (0.001) of a Preferred
Share (or, following a Triggering Event, other securities, cash or other assets
as the case may be) issuable upon exercise of the Rights hereunder with a
depositary agent, requisition from the depositary agent depositary receipts
representing such number of one-thousandths (0.001) of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets as the case
may be) as are to be purchased (in which case certificates for the Preferred
Shares (or, following a Triggering Event, other securities, cash or other assets
as the case may be) represented by such receipts shall be deposited by the
transfer agent with the depositary agent) and the Company hereby directs the
depositary agent to comply with such request, (ii) when appropriate, requisition
from the Company the amount of cash to be paid in lieu of issuance of fractional
shares in accordance with Section 14 hereof, (iii) after receipt of such
certificates or depositary receipts, cause the same to be delivered to or upon
the order of the registered holder of such Rights Certificate, registered in
such name or names as may be designated by such holder and (iv) when
appropriate, after receipt thereof, deliver such cash to or upon the order of
the registered holder of such Rights Certificate. The payment of the Exercise
Price (as such amount may be reduced (including to zero) pursuant to Section
11(a)(iii) hereof) and an amount equal to any applicable transfer tax required
to be paid by the holder of such Rights Certificate in accordance with Section
9(e) hereof, may be made in cash or by certified bank check, cashier's check or
bank draft payable to the order of the Company. In the event that the Company is
obligated to issue securities of the Company other than Preferred Shares, pay
cash and/or distribute other property pursuant to Section 11(a) hereof, the
Company will make all arrangements necessary so that such other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when appropriate.

                  (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 to the registered holder of such Rights
Certificate or to his or her duly authorized assigns, subject to the provisions
of Section 14 hereof.

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Triggering 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

                                      -11-
<PAGE>

(a "Post-Event Transferee"), (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 regarding the transferred Rights or (B) a transfer
which the Company's Board of Directors has determined is part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of this Section 7(e) (a "Pre-Event Transferee") or (iv) any subsequent
transferee receiving transferred Rights from a Post-Event Transferee or a
Pre-Event Transferee, either directly or through one or more intermediate
transferees, shall become null and void without any further action and no holder
of such Rights shall have any rights whatsoever with respect to such Rights,
whether under any provision of this Agreement or otherwise. The Company shall
use all reasonable efforts to ensure that the provisions of this Section 7(e)
and Section 4(b) hereof are complied with, but shall have no liability to any
holder of Rights Certificates or to any other Person as a result of its failure
to make any determinations with respect to an Acquiring Person or any of such
Acquiring Person's 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 exercise as set forth in this Section 7 unless such registered
holder shall, in addition to having complied with the requirements of Section
7(a), have (i) completed and signed the certificate contained in the form of
election to purchase set forth on the reverse side of the Rights Certificate
surrendered for such exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request.

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

         Section 9. Reservation and Availability of Preferred Shares.

                  (a) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept available out of its authorized and
unissued Preferred Shares not reserved for another purpose (and, following the
occurrence of a Triggering Event, out of its authorized and unissued Common
Shares and/or other securities), the number of Preferred Shares (and, following
the occurrence of the Triggering Event, Common Shares and/or other securities)
that will be sufficient to permit the exercise in full of all outstanding
Rights.

                                      -12-
<PAGE>

                  (b) If the Company shall hereafter list any of its Preferred
Shares on a national securities exchange, then so long as the Preferred Shares
(and, following the occurrence of a Triggering Event, Common Shares and/or other
securities) issuable and deliverable upon exercise of the Rights may be listed
on such exchange, the Company shall use its best efforts to cause, from and
after such time as the Rights become exercisable (but only to the extent that it
is reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such exchange 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
Triggering Event in which the consideration to be delivered by the Company upon
exercise of the Rights is described in Section 11(a)(ii) or Section 11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration statement under the Securities 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 and (iii) cause such registration statement to
remain effective (with a prospectus at all times meeting the requirements of the
Securities Act) until the earlier of (A) the date as of which the Rights are no
longer exercisable for such securities and (B) the date of expiration of the
Rights. The Company may temporarily suspend, for a period 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. Upon any such
suspension, the Company shall issue a public announcement stating, and notify
the Rights Agent, that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the suspension is no longer in effect. 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. Notwithstanding any provision of this Agreement to
the contrary, the Rights shall not be exercisable in any jurisdiction, unless
the requisite qualification in such jurisdiction shall have been obtained, or an
exemption therefrom shall be available, and until a registration statement has
been declared and remains effective.

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

                  (e) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
which may be payable in respect of the original issuance or delivery of the
Rights Certificates or of any Preferred Shares (or other securities of the
Company) upon the exercise of Rights. The Company shall not, however, be
required to pay any transfer tax which may be payable in respect of any transfer
or delivery of Rights Certificates to a person other than, or the issuance or
delivery of certificates or depositary receipts for the Preferred Shares (or
other securities of the Company) in a name other than that of, the registered
holder of the Rights Certificate evidencing Rights surrendered for exercise or
to issue or to deliver any certificates or depositary receipts for Preferred
Shares (or other securities of the Company) upon the exercise of any Rights
until any such tax shall have been paid (any such tax

                                      -13-
<PAGE>

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
is due.

         Section 10. Record Date. Each Person in whose name any certificate for
a number of one-thousandths (0.001) of a Preferred Share (or other securities of
the Company) is issued upon the exercise of Rights shall for all purposes be
deemed to have become the holder of record of Preferred Shares (or other
securities of the Company) represented thereby on, and such certificate shall be
dated, the date upon which the Rights Certificate evidencing such Rights was
duly surrendered and payment of the Total Exercise Price with respect to which
the Rights have been exercised (and any applicable transfer taxes) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the transfer books of the Company are closed, such Person shall be deemed
to have become the record holder of such shares on, and such certificate shall
be dated, the next succeeding Business Day on which the transfer books of the
Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Rights Certificate shall not be entitled to any rights of a holder
of Preferred Shares (or other securities of the Company) for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

         Section 11. Adjustment of Exercise Price, Number of Shares or Number of
Rights. The Exercise Price, the number and kind of shares or other property
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) Anything in this Agreement to the contrary
notwithstanding, in the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares (by reverse stock split or otherwise) into a
smaller number of Preferred Shares, or (D) issue any shares of its capital stock
in a reclassification of the Preferred Shares (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by dividing the Exercise Price in effect immediately prior to such time by a
fraction (the "Adjustment Fraction"), the numerator of which shall be the total
number of Preferred Shares (or shares of capital stock issued in such
reclassification of the Preferred Shares) outstanding immediately following such
time and the denominator of which shall be the total number of Preferred Shares
outstanding immediately prior to such time; provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than
the aggregate par value of the shares of capital stock of the Company issuable
upon exercise of such Right; and (2) the number of one-thousandths (0.001) of a
Preferred Share (or share of such other capital stock) issuable upon the
exercise of each Right shall equal the number of one-thousandths (0.001) of a
Preferred Share (or share of such other capital stock) as was issuable upon
exercise of a Right immediately prior to the occurrence of the event described
in clauses (A)-(D) of this Section 11(a)(i), multiplied by the Adjustment
Fraction; provided, however, that, no such adjustment shall be made pursuant to
this Section 11(a)(i) to the extent that there shall have simultaneously
occurred an event

                                      -14-
<PAGE>

described in clause (A), (B), (C) or (D) of Section 11(n) with a proportionate
adjustment being made thereunder. Each Common Share that shall become
outstanding after an adjustment has been made pursuant to this Section 11(a)(i)
shall have associated with it the number of Rights, exercisable at the Exercise
Price and for the number of one-thousandths (0.001) of a Preferred Share (or
shares of such other capital stock) as one Common Share has associated with it
immediately following the adjustment made pursuant to this Section 11(a)(i).

                           (ii) Subject to Section 24 of this Agreement, in the
event a Triggering Event shall have occurred, then promptly following such
Triggering Event each holder of a Right, except as provided in Section 7(e)
hereof, shall thereafter have the right to receive for each Right, upon exercise
thereof in accordance with the terms of this Agreement and payment of the
Exercise Price in effect immediately prior to the occurrence of the Triggering
Event, in lieu of a number of one-thousandths (0.001) of a Preferred Share, such
number of Common Shares of the Company as shall equal the quotient obtained by
(A) the product obtained by multiplying (1) the Exercise Price in effect
immediately prior to the occurrence of the Triggering Event by (2) the number of
one-thousandths (0.001) of a Preferred Share for which a Right was exercisable
(or would have been exercisable if the Distribution Date had occurred)
immediately prior to the first occurrence of a Triggering Event, by (B) fifty
percent (50%) of the Current Per Share Market Price for Common Shares on the
date of occurrence of the Triggering Event; provided, however, that the Exercise
Price and the number of Common Shares of the Company so receivable upon exercise
of a Right shall be subject to further adjustment as appropriate in accordance
with Section 11(e) hereof to reflect any events occurring in respect of the
Common Shares of the Company after the occurrence of the Triggering Event.

                           (iii) In lieu of issuing Common Shares in accordance
with Section 11(a)(ii) hereof, the Company may, if the Company's Board of
Directors determines that such action is necessary or appropriate and not
contrary to the interest of holders of Rights and, in the event that the number
of Common Shares which 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, or if any necessary regulatory approval for such issuance
has not been obtained by the Company, the Company shall: (A) determine the
excess of (1) the value of the Common Shares issuable upon the exercise of a
Right (the "Current Value") over (2) the Exercise Price (such excess, the
"Spread") and (B) with respect to each Right, make adequate provision to
substitute for such Common Shares, upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise Price, (3) other equity securities of the Company
(including, without limitation, shares or units of shares of any series of
preferred stock which the Company's Board of Directors has deemed to have the
same value as Common Shares (such shares or units of shares of preferred stock
are herein called "Common Stock Equivalents")), except to the extent that the
Company has not obtained any necessary shareholder or regulatory approval for
such issuance, (4) debt securities of the Company, except to the extent that the
Company has not obtained any necessary shareholder or regulatory approval for
such issuance, (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 Company's Board of Directors based upon the advice of a
nationally recognized investment banking firm selected by the Company's Board of
Directors; provided, however, if the Company shall not have made adequate
provision to deliver value pursuant to clause (B) above within thirty (30) days
following the later of (x) the first occurrence of a Triggering Event and (y)
the date on which the Company's right of redemption pursuant to

                                      -15-
<PAGE>

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 Exercise Price, Common Shares (to the extent available), except
to the extent that the Company has not obtained any necessary shareholder or
regulatory approval for such issuance, and then, if necessary, cash, which
shares and/or cash have an aggregate value equal to the Spread. If the Company's
Board of Directors shall determine in good faith that it is likely that
sufficient additional Common Shares could be authorized for issuance upon
exercise in full of the Rights or that any necessary regulatory approval for
such issuance will be obtained, the thirty (30) 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 or take
action to obtain such regulatory approval (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)
hereof, 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, to
take any action to obtain any required regulatory approval 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 issue a public announcement stating that the exercisability of the Rights
has been temporarily suspended, as well as a public announcement at such time as
the suspension is no longer in effect. For purposes of this Section 11(a)(iii),
the value of the Common Shares shall be the Current Per Share Market Price of
the Common Shares 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
Shares on such date.

                  (b) In case the Company shall, at any time after the date of
this Agreement, fix a record date for the issuance of rights, options or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring within forty-five (45) calendar days after such record date) to
subscribe for or purchase Preferred Shares or Equivalent Shares or securities
convertible into Preferred Shares or Equivalent Shares at a price per share (or
having a conversion price per share, if a security convertible into Preferred
Shares or Equivalent Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent Shares on such record date, then, in each
such case, the Exercise Price to be in effect after such record date shall be
determined by multiplying the Exercise Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of
Preferred Shares and Equivalent Shares (if any) outstanding on such record date,
plus the number of Preferred Shares or Equivalent Shares, as the case may be,
which the aggregate offering price of the total number of Preferred Shares or
Equivalent Shares, as the case may be, to be offered or issued (and/or the
aggregate initial conversion price of the convertible securities to be offered
or issued) would purchase at such current market price, and the denominator of
which shall be the number of Preferred Shares and Equivalent Shares (if any)
outstanding on such record date, plus the number of additional Preferred Shares
or Equivalent Shares, as the case may be, to be offered for subscription or
purchase (or into which the convertible securities so to be offered are
initially convertible); provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Company's
Board of Directors, whose determination

                                      -16-
<PAGE>

shall be described in a statement filed with the Rights Agent and shall be
binding on the Rights Agent and the holders of the Rights. Preferred Shares and
Equivalent Shares owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation. Such adjustment
shall be made successively whenever such a record date is fixed, and in the
event that such rights, options or warrants are not so issued, the Exercise
Price shall be adjusted to be the Exercise Price which would then be in effect
if such record date had not been fixed.

                  (c) In case the Company shall, at any time after the date of
this Agreement, fix a record date for the making of a distribution to all
holders of the Preferred Shares or of any class or series of Equivalent Shares
(including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation) of
evidences of indebtedness or assets (other than a regular quarterly cash
dividend, if any, or a dividend payable in Preferred Shares) or subscription
rights, options or warrants (excluding those referred to in Section 11(b)),
then, in each such case, the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
Current Per Share Market Price of a Preferred Share or an Equivalent Share on
such record date, less the fair market value per Preferred Share or Equivalent
Share (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent) 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 Preferred
Share or Equivalent Share, as the case may be, and the denominator of which
shall be such Current Per Share Market Price of a Preferred Share or Equivalent
Share on such record date; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. 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 Exercise Price shall be adjusted to be the Exercise Price which would have
been in effect if such record date had not been fixed.

                  (d) Anything herein to the contrary notwithstanding, no
adjustment in the Exercise Price shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) of the Exercise
Price; provided, however, that any adjustments which by reason of this Section
11(d) 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-thousandth (0.0001) of a
Common Share or other share or one hundred-thousandth (0.00001) of a Preferred
Share, as the case may be. Notwithstanding the first sentence of this Section
11(d), any adjustment required by this Section 11 shall be made no later than
the earlier of (i) three (3) years from the date of the transaction which
requires such adjustment or (ii) the Expiration Date.

                  (e) If as a result of an adjustment made pursuant to Section
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right and, if required, the Exercise 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 Shares contained in
Sections 11(a), 11(b), 11(c), 11(d), 11(g), 11(h), 11(i),

                                      -17-
<PAGE>

11(j), 11(k) and 11(l), and the provisions of Sections 7, 9, 10, 13 and 14 with
respect to the Preferred Shares shall apply on like terms to any such other
shares.

                  (f) All Rights originally issued by the Company subsequent to
any adjustment made to the Exercise Price hereunder shall evidence the right to
purchase, at the adjusted Exercise Price, the number of one-thousandths (0.001)
of a Preferred Share purchasable from time to time hereunder upon exercise of
the Rights, all subject to further adjustment as provided herein.

                  (g) Unless the Company shall have exercised its election as
provided in Section 11(h), upon each adjustment of the Exercise Price as a
result of the calculations made in Section 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 Exercise Price, that number of Preferred
Shares (calculated to the nearest one hundred-thousandth (0.00001) of a share)
obtained by (i) multiplying (x) the number of Preferred Shares covered by a
Right immediately prior to this adjustment, by (y) the Exercise Price in effect
immediately prior to such adjustment of the Exercise Price, and (ii) dividing
the product so obtained by the Exercise Price in effect immediately after such
adjustment of the Exercise Price.

                  (h) The Company may elect on or after the date of any
adjustment of the Exercise Price as a result of the calculations made in Section
11(b) or (c) to adjust the number of Rights, in substitution for any adjustment
in the number of Preferred Shares purchasable upon the exercise of a Right. Each
of the Rights outstanding after such adjustment of the number of Rights shall be
exercisable for the number of one-thousandths (0.001) of a Preferred Share for
which a Right was exercisable immediately prior to such adjustment. Each Right
held of record prior to such adjustment of the number of Rights shall become
that number of Rights (calculated to the nearest one hundred-thousandth
(0.00001)) obtained by dividing the Exercise Price in effect immediately prior
to adjustment of the Exercise Price by the Exercise Price in effect immediately
after adjustment of the Exercise Price. The Company shall make a public
announcement of its election to adjust the number of Rights, indicating the
record date for the adjustment, and, if known at the time, the amount of the
adjustment to be made. This record date may be the date on which the Exercise
Price is adjusted or any day thereafter, but, if any Rights Certificates have
been issued, shall be at least ten (10) 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(h), 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 hereof, the additional Rights to which such holders shall be entitled
as a result of such adjustment, or, at the option of the Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
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 Exercise 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.

                  (i) Irrespective of any adjustment or change in the Exercise
Price or the number of Preferred Shares issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue
to express the Exercise Price per one one-thousandth (0.001) of a

                                      -18-
<PAGE>

Preferred Share and the number of one-thousandths (0.001) of a Preferred
Share which were expressed in the initial Rights Certificates issued
hereunder.

            (j) Before taking any action that would cause an adjustment
reducing the Exercise Price below the par or stated value, if any, of the
number of one-thousandths (0.001) of a Preferred Share issuable upon
exercise of the Rights, the Company shall take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Company
may validly and legally issue as fully paid and nonassessable shares such
number of one-thousandths (0.001) of a Preferred Share at such adjusted
Exercise Price.

            (k) In any case in which this Section 11 shall require that an
adjustment in the Exercise Price be made effective as of a record date for
a specified event, the Company may elect to defer until the occurrence of
such event the issuing to the holder of any Right exercised after such
record date of the number of one-thousandths (0.001) of a Preferred Share
and other capital stock or securities of the Company, if any, issuable upon
such exercise over and above the number of one-thousandths (0.001) of a
Preferred Share and other capital stock or securities of the Company, if
any, issuable upon such exercise on the basis of the Exercise 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) upon the occurrence of the event requiring such
adjustment.

            (l) Anything in this Section 11 to the contrary
notwithstanding, prior to the Distribution Date, the Company shall be
entitled to make such reductions in the Exercise Price, in addition to
those adjustments expressly required by this Section 11, as and to the
extent that it in its sole discretion shall determine to be advisable in
order that any (i) consolidation or subdivision of the Preferred or Common
Shares, (ii) issuance wholly for cash of any Preferred or Common Shares at
less than the current market price, (iii) issuance wholly for cash of
Preferred or Common Shares or securities which by their terms are
convertible into or exchangeable for Preferred or Common Shares, (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
or Common Shares shall not be taxable to such shareholders.

            (m) The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Sections 23, 24 or
27 hereof, take (or permit to be taken) 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.

            (n) In the event the Company shall at any time after the date
of this Agreement (A) declare a dividend on the Common Shares payable in
Common Shares, (B) subdivide the outstanding Common Shares, (C) combine the
outstanding Common Shares (by reverse stock split or otherwise) into a
smaller number of Common Shares, or (D) issue any shares of its capital
stock in a reclassification of the Common Shares (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such
event, except as otherwise provided in this Section 11(a) and Section 7(e)
hereof: (1) each Common Share (or shares of capital stock issued in such
reclassification of the Common Shares) outstanding immediately following
such time shall have associated with it the number of Rights as were
associated with one Common Share immediately prior to the occurrence of the
event described

                                   -19-
<PAGE>

in clauses (A)-(D) above; (2) the Exercise Price in effect at the time of
the record date for such dividend or of the effective date of such
subdivision, combination or reclassification shall be adjusted so that the
Exercise Price thereafter shall equal the result obtained by multiplying
the Exercise Price in effect immediately prior to such time by a fraction,
the numerator of which shall be the total number of Common Shares
outstanding immediately prior to the event described in clauses (A)-(D)
above, and the denominator of which shall be the total number of Common
Shares outstanding immediately after such event; provided, however, that in
no event shall the consideration to be paid upon the exercise of one Right
be less than the aggregate par value of the shares of capital stock of the
Company issuable upon exercise of such Right; and (3) the number of
one-thousandths (0.001) of a Preferred Share (or shares of such other
capital stock) issuable upon the exercise of each Right outstanding after
such event shall equal the number of one-thousandths (0.001) of a Preferred
Share (or shares of such other capital stock) as were issuable with respect
to one Right immediately prior to such event. Each Common Share that shall
become outstanding after an adjustment has been made pursuant to this
Section 11(n) shall have associated with it the number of Rights,
exercisable at the Exercise Price and for the number of one-thousandths
(0.001) of a Preferred Share (or shares of such other capital stock) as one
Common Share has associated with it immediately following the adjustment
made pursuant to this Section 11(n). If an event occurs which would require
an adjustment under both this Section 11(n) and Section 11(a)(ii) hereof,
the adjustment provided for in this Section 11(n) shall be in addition to,
and shall be made prior to, any adjustment required pursuant to Section
11(a)(ii) hereof.

      Section 12. Certificate of Adjusted Exercise Price or Number of
Shares. Whenever an adjustment is made as provided in Sections 11 and 13
hereof, the Company shall promptly (a) prepare a certificate setting forth
such adjustment and a brief statement of the facts accounting for such
adjustment, (b) file with the Rights Agent and with each transfer agent for
the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Rights Certificate in accordance with
Section 26 hereof. Notwithstanding the foregoing sentence, the failure of
the Company to make such certification or give such notice shall not affect
the validity of such adjustment or the force or effect of the requirement
for such adjustment. The Rights Agent shall be fully protected in relying
on any such certificate and on any adjustment contained therein and shall
not be deemed to have knowledge of such adjustment unless and until it
shall have received such certificate.

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

            (a) In the event that, following a Triggering Event, directly
or indirectly:

                  (i) the Company shall consolidate with, or merge with and
into, any other Person (other than a wholly-owned Subsidiary of the Company
in a transaction the principal purpose of which is to change the state of
incorporation of the Company and which complies with Section 11(m) hereof);

                  (ii) any Person shall consolidate with the Company, or
merge with and into the Company and the Company shall be the continuing or
surviving corporation of such consolidation or merger and, in connection
with such merger, all or part of the Common Shares shall be changed into or
exchanged for stock or other securities of any other person (or the
Company); or

                                   -20-
<PAGE>

                  (iii) the Company shall sell or otherwise transfer (or
one or more of its Subsidiaries shall sell or otherwise transfer), in one
or more transactions, assets or earning power aggregating fifty percent
(50%) or more 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 or one or more of its wholly owned Subsidiaries in one or more
transactions, each of which individually (and together) complies with
Section 11(m) hereof),

                        then, concurrent with and in each such case,

                        (A) each holder of a Right (except as provided in
Section 7(e) hereof) shall thereafter have the right to receive, upon the
exercise thereof at a price equal to the Total Exercise Price applicable
immediately prior to the occurrence of the Section 13 Event in accordance
with the terms of this Agreement, such number of validly authorized and
issued, fully paid, nonassessable and freely tradeable Common Shares of the
Principal Party (as hereinafter defined), free of any liens, encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the
result obtained by dividing such Total Exercise Price by an amount equal to
fifty percent (50%) of the Current Per Share Market Price of the Common
Shares of such Principal Party on the date of consummation of such Section
13 Event, provided, however, that the Exercise Price and the number of
Common Shares of such Principal Party so receivable upon exercise of a
Right shall be subject to further adjustment as appropriate in accordance
with Section 11(e) hereof;

                        (B) 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;

                        (C) the term "Company" shall thereafter be deemed
to refer to such Principal Party, it being specifically intended that the
provisions of Section 11 hereof shall apply only to such Principal Party
following the first occurrence of a Section 13 Event;

                        (D) such Principal Party shall take such steps
(including, but not limited to, the reservation of a sufficient number of
its Common Shares) in connection with the consummation of any such
transaction as may be necessary to ensure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to
its Common Shares thereafter deliverable upon the exercise of the Rights;
and

                        (E) upon the subsequent occurrence of any
consolidation, merger, sale or transfer of assets or other extraordinary
transaction in respect of such Principal Party, each holder of a Right
shall thereupon be entitled to receive, upon exercise of a Right and
payment of the Total Exercise Price as provided in this Section 13(a), such
cash, shares, rights, warrants and other property which such holder would
have been entitled to receive had such holder, at the time of such
transaction, owned the Common Shares of the Principal Party receivable upon
the exercise of such Right pursuant to this Section 13(a), and such
Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may be necessary to permit the
subsequent exercise of the Rights in accordance with the terms hereof for
such cash, shares, rights, warrants and other property.

                                   -21-
<PAGE>

                        (F) For purposes hereof, the "earning power" of the
Company and its Subsidiaries shall be determined in good faith by the
Company's Board of Directors on the basis of the operating income of each
business operated by the Company and its Subsidiaries during the three
fiscal years preceding the date of such determination (or, in the case of
any business not operated by the Company or any Subsidiary during three
full fiscal years preceding such date, during the period such business was
operated by the Company or any Subsidiary).

            (b) For purposes of this Agreement, the term "Principal
Party" shall mean:

                  (i) in the case of any transaction described in clause
(i) or (ii) of Section 13(a) hereof: (A) the Person that is the issuer of
the securities into which the Common Shares are converted in such merger or
consolidation, or, if there is more than one such issuer, the issuer the
Common Shares of which have the greatest aggregate market value of shares
outstanding, or (B) if no securities are so issued, (x) the Person that is
the other party to the merger, if such Person survives said merger, or, if
there is more than one such Person, the Person the Common Shares of which
have the greatest aggregate market value of shares outstanding or (y) if
the Person that is the other party to the merger does not survive the
merger, the Person that does survive the merger (including the Company if
it survives) or (z) the Person resulting from the consolidation; and

                  (ii) in the case of any transaction described in clause
(iii) of Section 13(a) hereof, the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to
such transaction or transactions, or, if more than one Person that is a
party to such transaction or transactions receives the same portion of the
assets or earning power so transferred and each such portion would, were it
not for the other equal portions, constitute the greatest portion of the
assets or earning power so transferred, or if the Person receiving the
greatest portion of the assets or earning power cannot be determined,
whichever of such Persons is the issuer of Common Shares having the
greatest aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time
or have not been continuously over the preceding 12-month period registered
under Section 12 of the Exchange Act, then (1) if such Person is a direct
or indirect Subsidiary of another Person the Common Shares of which are and
have been so registered, the term "Principal Party" shall refer to such
other Person, or (2) if such Person is a Subsidiary, directly or
indirectly, of more than one Person, the Common Shares of which are and
have been so registered, the term "Principal Party" shall refer to
whichever of such Persons is the issuer of Common Shares having the
greatest aggregate market value of shares outstanding, or (3) if such
Person is owned, directly or indirectly, by a joint venture formed by two
or more Persons that are not owned, directly or indirectly by the same
Person, the rules set forth in clauses (1) and (2) above shall apply to
each of the owners having an interest in the venture as if the Person owned
by the joint venture was a Subsidiary of both or all of such joint
venturers, and the Principal Party in each such case shall bear the
obligations set forth in this Section 13 in the same ratio as its interest
in such Person bears to the total of such interests.

                  (c) The Company shall not consummate any Section 13 Event
unless the Principal Party shall have a sufficient number of authorized
Common Shares that have not been issued or reserved for issuance to permit
the exercise in full of the Rights in accordance with this Section 13 and
unless prior thereto the Company and such issuer shall have executed and
delivered

                                   -22-
<PAGE>

to the Rights Agent a supplemental agreement confirming that such Principal
Party shall, upon consummation of such Section 13 Event, assume this
Agreement in accordance with Sections 13(a) and 13(b) hereof, that all
rights of first refusal or preemptive rights in respect of the issuance of
Common Shares of such Principal Party upon exercise of outstanding Rights
have been waived, that there are no rights, warrants, instruments or
securities outstanding or any agreements or arrangements which, as a result
of the consummation of such transaction, would eliminate or substantially
diminish the benefits intended to be afforded by the Rights and that such
transaction shall not result in a default by such Principal Party under
this Agreement, and further providing that, as soon as practicable after
the date of such Section 13 Event, such Principal Party will:

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

                  (ii) use its best efforts to list (or continue the
listing of) the Rights and the securities purchasable upon exercise of the
Rights on a national securities exchange or to meet the eligibility
requirements for quotation on Nasdaq and list (or continue the listing of)
the Rights and the securities purchasable upon exercise of the Rights on
Nasdaq; and

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

      In the event that at any time after the occurrence of a Triggering
Event some or all of the Rights shall not have been exercised at the time
of a transaction described in this Section 13, the Rights which have not
theretofore been exercised shall thereafter be exercisable in the manner
described in Section 13(a) (without taking into account any prior
adjustment required by Section 11(a)(ii)).

                  (d) In case the "Principal Party" for purposes of Section
13(b) hereof has provision in any of its authorized securities or in its
certificate of incorporation or by-laws or other instrument governing its
corporate affairs, which provision would have the effect of (i) causing
such Principal Party to issue (other than to holders of Rights pursuant to
Section 13 hereof), in connection with, or as a consequence of, the
consummation of a Section 13 Event, Common Shares or Equivalent Shares of
such Principal Party at less than the then Current Per Share Market Price
thereof or securities exercisable for, or convertible into, Common Shares
or Equivalent Shares of such Principal Party at less than such then Current
Per Share Market Price, or (ii) providing for any special payment, tax or
similar provision in connection with the issuance of the Common Shares of
such Principal Party pursuant to the provisions of Section 13 hereof, then,
in such event, the Company hereby agrees with each holder of Rights that it
shall not consummate any such transaction unless prior thereto the Company
and such Principal Party shall have executed and delivered to the Rights
Agent a supplemental agreement providing that the provision in question of
such Principal Party shall have been canceled, waived or amended, or that
the authorized securities shall be

                                   -23-
<PAGE>

redeemed, so that the applicable provision will have no effect in
connection with or as a consequence of, the consummation of the proposed
transaction.

            (e) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, effect or permit to occur any Section 13
Event, if (i) at the time or immediately after such Section 13 Event there
are any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise
eliminate the benefits intended to be afforded by the Rights, (ii) prior
to, simultaneously with or immediately after such Section 13 Event, the
shareholders of the Person who constitutes, or would constitute, the
"Principal Party" for purposes of Section 13(b) hereof shall have received
a distribution of Rights previously owned by such Person or any of its
Affiliates or Associates or (iii) the form or nature of organization of the
Principal Party would preclude or limit the exercisability of the Rights.

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

      Section 14. Fractional Rights and Fractional Shares.

            (a) The Company shall not be required to issue fractions of
Rights or to distribute Rights Certificates which 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 the
purposes of this Section 14(a), the current market value of a whole Right
shall be the closing price of the Rights for the Trading Day immediately
prior to the date on which such fractional Rights would have been otherwise
issuable, as determined pursuant to the second sentence of Section 1(j)
hereof.

            (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions that are integral multiples of one
one-thousandth (0.001) of a Preferred Share) upon exercise of the Rights or
to distribute certificates which evidence fractional Preferred Shares
(other than fractions that are integral multiples of one one-thousandth
(0.001) of a Preferred Share). Interests in fractions of Preferred Shares
in integral multiples of one one-thousandth (0.001) of a Preferred Share
may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it; provided, that such agreement shall provide that the
holders of such depositary receipts shall have all the rights, privileges
and preferences to which they are entitled as beneficial owners of the
Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth (0.001) of a Preferred Share, 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 a Preferred Share. For purposes of this
Section 14(b), the current market value of a Preferred Share shall be (x)
one thousand multiplied by (y) the closing price of a Common Share (as
determined pursuant to the second sentence of Section 1(j) hereof) for the
Trading Day immediately prior to the date of such exercise.

            (c) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional
Common Shares upon the exercise or exchange of

                                   -24-
<PAGE>

Rights. In lieu of such fractional Common Shares, 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 a Common Share. For purposes of this Section
14(c), the current market value of a Common Share shall be the closing
price of a Common Share (as determined pursuant to the second sentence of
Section 1(j) hereof) for the Trading Day immediately prior to the date of
such exercise.

            (d) The holder of a Right by the acceptance of the Right
expressly waives his or her right to receive any fractional Rights or any
fractional shares (other than fractions that are integral multiples of one
one-thousandth (0.001) of a Preferred Share) upon exercise of a Right.

      Section 15. Rights of Action. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent
pursuant to Section 18 hereof, are vested in the respective registered
holders of the Rights Certificates (and, prior to the Distribution Date,
the registered holders of the Common Shares); and any registered holder of
any Rights Certificate (or, prior to the Distribution Date, of the Common
Shares), without the consent of the Rights Agent or of the holder of any
other Rights Certificate (or, prior to the Distribution Date, of the Common
Shares), may, in his or her own behalf and for his or her 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 or her
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 will be
entitled to specific performance of the obligations under, and injunctive
relief against actual or threatened violations of, the obligations of any
Person subject to this Agreement.

      Section 16. Agreement of 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 the Common Shares;

            (b) after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent if surrendered
at the principal office or offices of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper instrument of transfer
and with the appropriate forms and certificates fully executed; and

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

                                   -25-
<PAGE>

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

      Section 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 other disbursements incurred in the administration and execution
of this Agreement and the exercise and performance of its duties hereunder.
The Company also agrees to indemnify the Rights Agent for, and to hold it
harmless against, any loss, liability or expense, incurred without gross
negligence, bad faith or willful misconduct on the part of the Rights
Agent, for anything done or omitted by the Rights Agent in connection with
the acceptance and administration of this Agreement, including the costs
and expenses of defending against any claim of liability in the premises.
In no event will the Rights Agent be liable for special, indirect,
incidental or consequential loss or damage of any kind whatsoever, even if
the Rights Agent has been advised of the possibility of such loss or
damage.

            (b) The Rights Agent shall be protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it
in connection with, its administration of this Agreement in reliance upon
any Rights Certificate or certificate for the Preferred Shares or Common
Shares or for other securities of the Company, instrument of assignment or
transfer, power of attorney, endorsement, affidavit, letter, notice,
direction, consent, certificate, statement or other paper or document
reasonably 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.

      Section 19. Merger or Consolidation or Change of Name of Rights
Agent.

            (a) Any corporation into which the Rights Agent or any
successor Rights Agent may be merged or with which it may be consolidated,
or any corporation resulting from any merger or consolidation to which the
Rights Agent or any successor Rights Agent shall be a party, or any
corporation succeeding to the corporate trust business of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent
under this Agreement without the execution or filing of any paper or any
further act on the part of any of the parties hereto; provided, however,
that such corporation would be eligible for appointment as a successor
Rights Agent under the provisions of Section 21 hereof. In case at the time
such successor Rights Agent shall succeed to the agency created by this
Agreement, any of the Rights Certificates shall have been countersigned but
not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor

                                   -26-
<PAGE>

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 Rights Agent 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.

            (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.

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

            (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any
fact or matter (including, without limitation, the identity of any
Acquiring Person and the determination of Current Per Share Market Price)
be proved or established by the Company prior to taking or suffering any
action hereunder, such fact or matter (unless other evidence in respect
thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by any one of the Chairman
of the Board, the Chief Executive Officer, the President, any Vice
President, the Chief Financial Officer, the Secretary or any Assistant
Secretary of the Company and delivered to the Rights Agent; and such
certificate shall be full authorization to the Rights Agent for any action
taken or suffered in good faith by it under the provisions of this
Agreement in reliance upon such certificate.

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

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

            (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery
hereof (except the due execution hereof by the Rights Agent) or in respect
of the validity or execution of any Rights Certificate (except its
countersignature thereof); nor shall it be responsible for any breach by
the Company of any covenant or condition contained in this Agreement or in
any Rights Certificate; nor shall it be responsible for

                                   -27-
<PAGE>

any change in the exercisability of the Rights or any adjustment in the
terms of the Rights (including the manner, method or amount thereof)
provided for in Sections 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except
with respect to the exercise of Rights evidenced by Rights Certificates
after receipt by the Rights Agent of a certificate furnished pursuant to
Section 12 describing such change or adjustment); nor shall it by any act
hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant
to this Agreement or any Rights Certificate or as to whether any Preferred
Shares will, when issued, be validly authorized and issued, fully paid and
nonassessable.

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

            (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder
from any one of the Chairman of the Board, the Chief Executive Officer, the
President, any Vice President, the Chief Financial Officer, the Secretary
or any Assistant Secretary of the Company, and to apply to such officers
for advice or instructions in connection with its duties, and it shall not
be liable for any action taken or suffered by it in good faith in
accordance with instructions of any such officer or for any delay in acting
while waiting for those instructions. Any application by the Rights Agent
for written instructions from the Company may, at the option of the Rights
Agent, set forth in writing any action proposed to be taken or omitted by
the Rights Agent under this Rights Agreement and the date on and/or after
which such action shall be taken or such omission shall be effective. The
Rights Agent shall not be liable for any action taken by, or omission of,
the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date
shall not be less than five (5) Business Days after the date on which 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 or omitted.

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

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

                                   -28-
<PAGE>

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

            (k) If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate attached to the
form of assignment or form of election to purchase, as the case may be, has
either not been completed or indicates an affirmative response to clause 1
and/or 2 thereof, the Rights Agent shall not take any further action with
respect to such requested exercise or transfer without first consulting
with the Company.

      Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Company
and to each transfer agent of the Preferred Shares and the Common Shares by
registered or certified mail, and to the holders of the Rights Certificates
by first-class mail. The Company may remove the Rights Agent or any
successor Rights Agent upon thirty (30) days' notice in writing, mailed to
the Rights Agent or successor Rights Agent, as the case may be, and to each
transfer agent of the Preferred Shares and the Common Shares 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 (30) days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the holder of a Rights
Certificate (who shall, with such notice, submit his or her Rights
Certificate for inspection by the Company), then the 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 an entity 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 powers and is subject to
supervision or examination by federal or state authority and which has at
the time of its appointment as Rights Agent a combined capital and surplus
of at least $30 million (provided that such requirement shall not apply to
the initial Rights Agent). 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 Preferred Shares
and the Common Shares, 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.

            Section 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 its Board of Directors
to reflect

                                   -29-
<PAGE>

any adjustment or change in the Exercise 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. In addition, in connection with the issuance or sale of Common
Shares following the Distribution Date and prior to the redemption or
expiration of the Rights, the Company (a) shall, with respect to Common
Shares so issued or sold pursuant to the exercise of stock options or under
any employee plan or arrangement or upon the exercise, conversion or
exchange of other securities of the Company outstanding at the date hereof
or upon the exercise, conversion or exchange of securities hereinafter
issued by the Company and (b) may, in any other case, if deemed necessary
or appropriate by the Board of Directors of the Company, issue Rights
Certificates representing the appropriate number of Rights in connection
with such issuance or sale; provided, however, that (i) no such Rights
Certificate shall be issued and this sentence shall be null and void ab
initio if, and to the extent that, such issuance or this sentence would
create a significant risk of or result in material adverse tax consequences
to the Company or the Person to whom such Rights Certificate would be
issued or would create a significant risk of or result in such options' or
employee plans' or arrangements' failing to qualify for otherwise available
special tax treatment and (ii) 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.

      Section 23. Redemption.

            (a) The Company may, at its option and with the approval of the
Board of Directors, at any time prior to the Close of Business on the
earlier of (i) the fifth day following the Shares Acquisition Date (or such
later date as may be determined by action of the Company's Board of
Directors and publicly announced by the Company) and (ii) the Final
Expiration Date, redeem all but not less than all the then outstanding
Rights at a redemption price of $0.001 per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring
after the date hereof (such redemption price being herein referred to as
the "Redemption Price") and the Company may, at its option, pay the
Redemption Price either in Common Shares (based on the Current Per Share
Market Price thereof at the time of redemption) or cash. Such redemption of
the Rights by the Company may be made effective at such time, on such basis
and with such conditions as the Board of Directors in its sole discretion
may establish. The date on which the Board of Directors elects to make the
redemption effective shall be referred to as the "Redemption Date."

            (b) Immediately upon the action of the Board of Directors of
the Company ordering the redemption of the Rights, evidence of which shall
have been filed with the Rights Agent, and without any further action and
without any notice, the right to exercise the Rights will terminate and the
only right thereafter of the holders of Rights shall be to receive the
Redemption Price. The Company shall promptly give public notice of any such
redemption; provided, however, that the failure to give, or any defect in,
any such notice shall not affect the validity of such redemption. Within
ten (10) days after the action of the Board of Directors 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 their last addresses as they
appear upon the registry books of the Rights Agent or, prior to the
Distribution Date, on the registry books of the transfer agent for the
Common Shares. Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice. Each
such notice of redemption will state the method by which the payment of the
Redemption Price will be made. Neither the Company nor any of its
Affiliates or Associates may redeem, acquire or

                                   -30-
<PAGE>

purchase for value any Rights at any time in any manner other than that
specifically set forth in this Section 23 or in Section 24 hereof, and
other than in connection with the purchase of Common Shares prior to the
Distribution Date.

      Section 24. Exchange.

            (a) Subject to applicable laws, rules and regulations, and
subject to subsection 24(c) below, the Company may, at its option, by
action of the Board of Directors, at any time after the occurrence of a
Triggering Event, exchange all or part of the then outstanding and
exercisable Rights (which shall not include Rights that have become void
pursuant to the provisions of Section 7(e) hereof) for Common Shares at an
exchange ratio of one Common Share per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring
after the date hereof (such exchange ratio being hereinafter referred to as
the ("Exchange Ratio"). Notwithstanding the foregoing, the Board of
Directors shall not be empowered to effect such exchange at any time after
any Person (other than the Company, any Subsidiary of the Company, any
employee benefit plan of the Company or any such Subsidiary, or any entity
holding Common Shares for or pursuant to the terms of any such plan),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the Common Shares then outstanding.

            (b) Immediately upon the action of the Board of Directors
ordering the exchange of any Rights pursuant to subsection 24(a) of this
Section 24 and without any further action and without any notice, the right
to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of Common Shares
equal to the number of such Rights held by such holder multiplied by the
Exchange Ratio. The Company shall 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 shall mail a
notice of any such exchange to all of the holders of such Rights at their
last addresses as they appear upon the registry books of the Rights Agent.
Any notice which is mailed in the manner herein provided shall be deemed
given, whether or not the holder receives the notice. Each such notice of
exchange will state the method by which the exchange of the Common Shares
for Rights will be effected and, in the event of any partial exchange, the
number of Rights which will be exchanged. Any partial exchange shall be
effected pro rata based on the number of Rights (other than Rights which
have become void pursuant to the provisions of Section 7(e) hereof) held by
each holder of Rights.

            (c) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with Section 24(a), the
Company shall either take such action as may be necessary to authorize
additional Common Shares for issuance upon exchange of the Rights or
alternatively, at the option of a majority of the Board of Directors, with
respect to each Right (i) pay cash in an amount equal to the Current Value
(as hereinafter defined), in lieu of issuing Common Shares in exchange
therefor, or (ii) issue debt or equity securities or a combination thereof,
having a value equal to the Current Value, in lieu of issuing Common Shares
in exchange for each such Right, where the value of such securities shall
be determined by a nationally recognized investment banking firm selected
by majority vote of the Board of Directors, or (iii) deliver any
combination of cash, property, Common Shares and/or other securities having
a value equal to the Current Value in exchange for each Right. For purposes
of this Section 24(c) only, the Current Value shall mean the

                                   -31-
<PAGE>

product of the Current Per Share Market Price of Common Shares on the date
of the occurrence of the event described above in subparagraph (a),
multiplied by the number of Common Shares for which the Right otherwise
would be exchangeable if there were sufficient shares available. To the
extent that the Company determines that some action need be taken pursuant
to clauses (i), (ii) or (iii) of this Section 24(c), the Board of Directors
may temporarily suspend the exercisability of the Rights for a period of up
to sixty (60) days following the date on which the event described in
Section 24(a) shall have occurred, in order to seek any authorization of
additional Common Shares and/or to decide the appropriate form of
distribution to be made pursuant to the above provision and to determine
the value thereof. In the event of any such suspension, the Company shall
issue a public announcement stating that the exercisability of the Rights
has been temporarily suspended.

            (d) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional
Common Shares. In lieu of such fractional Common Shares, there shall be
paid to the registered holders of the Rights Certificates with regard to
which such fractional Common Shares would otherwise be issuable, an amount
in cash equal to the same fraction of the current market value of a whole
Common Share (as determined pursuant to the second sentence of Section 1(k)
hereof).

            (e) The Company may, at its option, by majority vote of the
Board of Directors, at any time before any Person has become an Acquiring
Person, exchange all or part of the then outstanding Rights for rights of
substantially equivalent value, as determined reasonably and with good
faith by the Board of Directors, based upon the advice of one or more
nationally recognized investment banking firms.

            (f) Immediately upon the action of the Board of Directors
ordering the exchange of any Rights pursuant to subsection 24(e) of this
Section 24 and without any further action and without any notice, the right
to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of rights in exchange
therefor as has been determined by the Board of Directors in accordance
with subsection 24(e) above. The Company shall 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
shall mail a notice of any such exchange to all of the holders of such
Rights at their last addresses as they appear upon the registry books of
the transfer agent for the Common Shares of the Company. Any notice which
is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state
the method by which the exchange of the Rights will be effected.

      Section 25. Notice of Certain Events.

            (a) In case the Company shall propose to effect or permit to
occur any Triggering Event or Section 13 Event, the Company shall give
notice thereof to each holder of Rights in accordance with Section 26
hereof at least twenty (20) days prior to occurrence of such Triggering
Event or such Section 13 Event.

            (b) In case any Triggering Event or Section 13 Event shall
occur, then, in any such case, the Company shall as soon as practicable
thereafter give to each holder of a Rights Certificate, in accordance with
Section 26 hereof, a notice of the occurrence of such event, which

Rights under Sections 11(a)(ii) and 13 hereof.

any respect without the approval of any holders of Rights and the Rights
Agent shall, if the Company so directs, execute such supplement or
amendment. From and after the occurrence of a Distribution Date, the

protecting, enhancing or clarifying the rights of, and/or the benefits to,
the holders of Rights (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,

hereunder.

      Section 29. Determinations and Actions by the Board of Directors,
etc. For all purposes of this Agreement, any calculation of the number of
Common Shares outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding Common Shares of
which any Person is the Beneficial Owner, shall be made in accordance with
the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and
Regulations under the Exchange Act. The Board of Directors of the Company
shall have the exclusive power and authority to administer this Agreement
and to exercise all rights and powers specifically granted to the Board, or
the Company, or as may be necessary or advisable in the administration of
this Agreement, including, without limitation, the right and power to (i)
interpret the provisions of this Agreement and (ii) make all determinations
deemed necessary or advisable for the administration of this Agreement
(including a determination to redeem or not redeem the Rights or to amend
the Agreement). All such actions, calculations, interpretations and
determinations (including, for purposes of clause (y) below, all omissions
with respect to the foregoing) which are done or made by the Board of
Directors in good faith, shall (x) be final, conclusive and binding on the
Company, the Rights Agent, the holders of the Rights Certificates and all
other parties and (y) not subject the Board of Directors to any liability

shall be construed to give to any Person other than the Company, the Rights
Agent and the registered holders of the Rights Certificates (and, prior to
the Distribution Date, the Common Shares) any legal or equitable right,
remedy or claim pursuant to this Agreement; but this Agreement shall be for
the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the
Distribution Date, the Common Shares).

      Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction
or other authority to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall
remain in full force and effect and shall in no way be affected, impaired
or invalidated; provided, however, that notwithstanding anything in this
Agreement to the contrary, if any such term, provision, covenant or
restriction is held by such court or authority to be invalid, void or
unenforceable and the Board of Directors of the Company determines in its
good faith judgment that severing the invalid language from this Agreement
would adversely affect the purpose or effect of this Agreement, the right
of redemption set forth in Section 23 hereof shall be reinstated and shall
not expire until the Close of Business on the tenth day following the date
of such determination by the Board of Directors.

                   SERIES A PARTICIPATING PREFERRED STOCK
                         OF CHOLESTECH CORPORATION

      The undersigned, Warren E. Pinckert II and Andrea Tiller do hereby
certify:

      1. That they are the duly elected and acting President and Chief
Executive Officer and Chief Financial Officer and Secretary of Cholestech
Corporation, a California corporation (the "Corporation").

      2. That pursuant to the authority conferred upon the Board of
Directors by the Articles of Incorporation of the said Corporation, the
said Board of Directors on January 22, 1997 adopted the following
resolution creating a series of 25,000 shares of Preferred Stock designated
as Series A Participating Preferred Stock:

      "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the corporation by the Articles of Incorporation, the Board of
Directors does hereby provide for the issue of a series of Preferred Stock
of the Corporation and does hereby fix and herein state and express the
designations, powers, preferences and relative and other special rights and
the qualifications, limitations and restrictions of such series of
Preferred Stock as follows:

      Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Participating Preferred Stock." The Series A
Participating Preferred Stock shall have no par value, and the number of
shares constituting such series shall be 25,000.

      Section 2. Proportional Adjustment. In the event the Corporation
shall at any time after the issuance of any share or shares of Series A
Participating Preferred Stock (i) declare any dividend on Common Stock of
the Corporation ("Common Stock") payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock or (iii) combine the outstanding
Common Stock into a smaller number of shares, then in each such case the
Corporation shall simultaneously effect a proportional adjustment to the
number of outstanding shares of Series A Participating Preferred Stock.

      Section 3. Dividends and Distributions.

            (a) Subject to the prior and superior right of the holders of
any shares of any series of Preferred Stock ranking prior and superior to
the shares of Series A Participating Preferred Stock with respect to
dividends, the holders of shares of Series A Participating Preferred Stock
shall be entitled to receive when, as and if declared by the Board of
Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the last day of March, June, September and
December, 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 Participating Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to 1,000 times the aggregate per share
amount of all cash dividends, and 1,000 times the aggregate per share
amount (payable in kind) of all non-cash

<PAGE>

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 Participating Preferred Stock.

            (b) The Corporation shall declare a dividend or distribution on
the Series A Participating Preferred Stock as provided in paragraph (a)
above immediately after it declares a dividend or distribution on the
Common Stock (other than a dividend payable in shares of Common Stock).

            (c) Dividends shall begin to accrue on outstanding shares of
Series A Participating Preferred Stock from the Quarterly Dividend Payment
Date next preceding the date of issue of such shares of Series A
Participating Preferred Stock, 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 Participating 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 from
such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series A Participating
Preferred Stock in an amount less than the total amount of such dividends
at the time accrued and payable on such shares shall be allocated pro rata
on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of
holders of shares of Series A Participating Preferred Stock entitled to
receive payment of a dividend or distribution declared thereon, which
record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

      Section 4. Voting Rights. The holders of shares of Series A
Participating Preferred Stock shall have the following voting rights:

            (a) Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a
vote of the shareholders of the Corporation.

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

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

      Section 5. Certain Restrictions.

            (a) The Corporation shall not declare any dividend on, make any
distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a
share or fraction of a share of Series A Participating Preferred Stock
unless

                                    A-2
<PAGE>

concurrently therewith it shall declare a dividend on the Series A
Participating Preferred Stock as required by Section 3 hereof.

            (b) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as
provided in Section 3 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Participating Preferred Stock outstanding shall have been paid in
full, the Corporation shall not

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

                  (ii) declare or pay dividends on, 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 Series A
Participating Preferred Stock, except dividends paid ratably on the Series
A Participating 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 on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Series A
Participating Preferred Stock, provided that the Corporation may at any
time redeem, purchase or otherwise acquire shares of any such parity 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 Participating Preferred Stock;

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

            (c) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares
of stock of the Corporation unless the Corporation could, under paragraph
(a) of this Section 5, purchase or otherwise acquire such shares at such
time and in such manner.

      Section 6. Reacquired Shares. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any
manner whatsoever shall be retired and canceled 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 to be created by resolution or
resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein and, in the Articles of
Incorporation, as then amended.

                                    A-3
<PAGE>
      Section 7. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, the holders of
shares of Series A Participating Preferred Stock shall be entitled to
receive an aggregate amount per share equal to 1000 times the aggregate
amount to be distributed per share to holders of shares of Common Stock
plus an amount equal to any accrued and unpaid dividends on such shares of
Series A Participating Preferred Stock.

      Section 8. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other
stock or securities, cash and/or any other property, then in any such case
the shares of Series A Participating Preferred Stock shall at the same time
be similarly exchanged or changed in an amount per share 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.

      Section 9. No Redemption. The shares of Series A Participating
Preferred Stock shall not be redeemable.

      Section 10. Ranking. The Series A Participating Preferred Stock shall
rank junior to all other series of the Corporation's Preferred Stock as to
the payment of dividends and the distribution of assets, unless the terms
of any such series shall provide otherwise.

      Section 11. Amendment. The Articles of Incorporation of the
Corporation shall not be further amended in any manner which would
materially alter or change the powers, preference or special rights of the
Series A Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of a majority of the
outstanding shares of Series A Participating Preferred Stock, voting
separately as a class.

      Section 12. Fractional Shares. Series A Participating Preferred Stock
may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of
all other rights of holders of Series A Participating Preferred Stock.

      RESOLVED FURTHER, that the President or any Vice President and the
Secretary or any Assistant Secretary of this corporation be, and they
hereby are, authorized and directed to prepare and file a Certificate of
Determination of Rights, Preferences and Privileges in accordance with the
foregoing resolution and the provisions of California law and to take such
actions as they may deem necessary or appropriate to carry out the intent
of the foregoing resolution."

      3. That the authorized number of shares of Preferred Stock of the
Corporation is 5,000,000 and that no such Preferred Stock has been issued.

<S>                      <C>
Distribution and         The Board of Directors has declared a dividend of one
Transfer of Rights;      Right for each share of Cholestech Corporation Common
Rights Certificate:      Stock outstanding. Prior to the Distribution Date
                         referred to below, the Rights will be evidenced by and
                         trade with the certificates for the Common Stock. After
                         the Distribution Date, Cholestech Corporation (the
                         "Company") will mail Rights certificates to the
                         Company's shareholders and the Rights will become
                         transferable apart from the Common Stock.

Distribution Date:       Rights will separate from the Common Stock and become
                         exercisable following (a) the tenth business day after
                         a person or group acquires beneficial ownership of 15%
                         or more of the Company's Common Stock or (b) the tenth
                         business day (or such later date as may be determined
                         by the Company's Board of Directors) after a person or
                         group announces a tender or exchange offer, the
                         consummation of which would result in ownership by a
                         person or group of 15% or more of the Company's Common
                         Stock.

Preferred Stock          After the Distribution Date, each Right will entitle
Purchasable              the holder to purchase for $44.00 (the "Exercise
Exercise of Rights:      Price"), a fraction of a share of the Company's
                         Preferred Stock with economic terms similar to that of
                         one share of the Company's Common Stock.

Flip-In:                 If an acquiror (an "Acquiring Person") obtains 15% or
                         more of the Company's Common Stock, then each Right
                         (other than Rights owned by an Acquiring Person or its
                         affiliates) will entitle the holder thereof to
                         purchase, for the Exercise Price, a number of shares of
                         the Company's Common Stock having a then current market
                         value of twice the Exercise Price.

Flip-Over:               If, after an Acquiring Person obtains 15% or more of
                         the Company's Common Stock, (a) the Company merges into
                         another entity, (b) an acquiring entity merges into the
                         Company or (c) the Company sells more than 50% of the
                         Company's assets or earning power, then each Right
                         (other than Rights owned by an Acquiring Person or its
                         affiliates) will entitle the holder thereof to
                         purchase, for the Exercise Price, a number of shares of
                         Common Stock of the person engaging in the transaction
                         having a then current market value of twice the

                         prior to the acquisition by the Acquiring Person of 50%
                         of the outstanding Common Stock, the Board of Directors
                         may exchange the Rights (other than Rights owned by the
                         Acquiring Person or its affiliates), in whole or in
                         part, for shares of Common Stock of the Company at an
                         exchange ratio of one share of Common Stock per Right
                         (subject to adjustment).

Redemption of            Rights will be redeemable at the Company's option for
the Rights:              $0.001 per Right at any time on or prior to the fifth
                         day (or such later date as may be determined by the
                         Company's Board of Directors) after public announcement
                         that a Person has acquired beneficial ownership of 15%
                         or more of the Company's Common Stock (the "Shares
                         Acquisition Date").

Expiration of            The Rights expire on the earliest of (a) January 22,
the Rights:              2007 or (b) exchange or redemption of the Rights as
                         described above.

Amendment of             The terms of the Rights and the Rights Agreement may be
Terms of Rights:         amended in any respect without the consent of the
                         Rights holders on or prior to the Distribution Date;

                         Agreement may be amended without the consent of the
                         Rights holders in order to cure any ambiguities or to
                         make changes which do not adversely affect the
                         interests of Rights holders (other than the Acquiring
                         Person).

                         federal income tax purposes. However, following an
                         event which renders the Rights exercisable or upon
                         redemption of the Rights, shareholders may recognize
                         taxable income.
