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

        On February 23, 1998, the Board of Directors of HemaCare Corporation,
        a California corporation (the "Company"), declared a dividend of one
        preferred share purchase right (a "Right") for each outstanding share
        of common stock, without par value (the "Common Shares"), of the
        Company.  The dividend is payable on March 10, 1998 to the shareholders
        of record on March 3, 1998  (the "Record Date").  Each Right entitles
        the registered holder to purchase from the Company one one-hundredth of
        a share of Series A Junior Participating Preferred Stock, without par
        value (the "Preferred Shares"), of the Company, at a price of $5.00 per
        one-hundredth of a Preferred Share (the "Purchase Price"), subject to
        adjustment.  The description and terms of the Rights are set forth in a
        Rights Agreement (the "Rights Agreement") between the Company and U.S.
        Stock Transfer Company, as Rights Agent (the "Rights Agent").

	Until the earlier to occur of:

            (i)     the close of business on the tenth day after a public
            announcement that a person or a group of affiliated or associated
            persons (other than the Company, any subsidiary of the Company, any
            employee benefit plan of the Company or a subsidiary of the
            Company or any entity holding Common Shares for or pursuant to
            the terms of any such plan) (an "Acquiring Person") has acquired
            beneficial ownership of 15% or more of the outstanding Common
            Shares;

            (ii)    the close of business on tenth business day (or such later
            date as may be determined by action of the Board of Directors prior
            to such time as any person becomes an Acquiring Person) after the
            commencement of, or the first public announcement of an intention of
            any person (other than the Company, any subsidiary of the Company,
            any employee benefit plan of the Company or a subsidiary of the
            Company or any entity holding Common Shares for or pursuant to any
            such plan) to commence, a tender or exchange offer the consummation
            of which would result in the beneficial ownership by such person or
            group of 15% or more of the then outstanding Common Shares;

            (iii)   the close of business on the tenth day after all of the
            following events have occurred:  (A) the Board of Directors
            designates a specific limitation (the "Ownership Limitation") on
            the amount of Common Stock which a specified person may
            beneficially own (which may be more or less than such person
            actually then owns), (B) the Board determines (x) that the
            acquisition by such person of an amount of Common Shares
            exceeding the Ownership Limitation is, or would likely be,
            intended to cause the Company to repurchase the Common Shares
            beneficially owned by such person or to cause pressure on the
            Company to take action or enter into a transaction or series of
            transactions intended to provide such person with short-term
            financial gain under

                                         -2-
<PAGE>
            circumstances where the Board determines that the best long- term
            interests of the Company and its shareholders would not be served by
            taking such action or entering into such transactions at that time,
            or (y) that Beneficial Ownership by such Person of an amount of 
            Common Shares exceeding the Ownership Limitation is causing or 
            reasonably likely to cause a material adverse impact (including, but
            not limited to, impairment of relationships with customers or 
            impairment of the Company's ability to maintain its competitive 
            position) on the business or prospects of the Company, and (C) the 
            specified person or group obtains or has obtained (either before or 
            after the events described in (A) and (B), above) a number of shares
            of Common Stock which exceeds the Ownership Limitation (thereby 
            becoming an "Adverse Person"); or

            (iv)    with respect to the dates described in (i) and (ii), above,
            such later date or dates as the Board of Directors may designate;
            provided, that if a later date or dates are designated, such
            designation shall be made on or before the earlier of the dates
            specified in (i) or (ii), above;

            (the earlier of such dates being called the "Distribution Date"), 
            the Rights will be evidenced, with respect to any of the Common 
            Share certificates outstanding as of the Record Date, by such Common
            Share certificate with a copy of this Summary of Rights attached to 
            the Rights Agreement as Exhibit C (the "Summary of Rights") 
            attached thereto.

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

The Rights are not exercisable until the Distribution Date.  The Rights will
expire on March 10, 2008 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed by the
company, in each case as described below.

The Purchase Price payable, and the number of Preferred Shares or other 
securities or property issuable, upon Exercise of the Rights are subject to
adjustment from time to time to prevent dilution in the event that the
Company (i) declares a dividend on the Preferred Shares that is payable in
                                         -3-
<PAGE>

Preferred Shares, (ii) subdivides, combines or reclassifies the outstanding
Preferred Shares, (iii) grants to holders of the Preferred Shares certain
rights or warrants to subscribe for or purchase Preferred Shares at a price,
or securities convertible into Preferred Shares with a conversion price,
less than the then current market price of the Preferred Shares, or (iv)
distributes to holders of the Preferred Shares evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or subscription
rights or warrants (other than those referred to above).

In the event that (i) any person becomes an Acquiring Person (unless such
person first acquires 15% or more of the outstanding Common Shares through a
tender offer which meets all of the following criteria:  the tender offer (A)
is made in the manner prescribed by Section 14(d) of the Securities Exchange
Act of 1934, as amended, and the rules of the Securities and Exchange
Commission, (B) is delivered to the Company in a written proposal, (C) is
made by a person who both owns 1% or less of the Company's outstanding Common
Stock and has not, during the last year, indicated an interest in acquiring
control of the Company at any time when it owned more than 1% of the
outstanding Common Stock, (D) is for the acquisition of all the Company's
outstanding Common Stock and other voting securities for cash, (E) is
accompanied by a written opinion of a nationally recognized investment
banking firm stating that the price to be paid for each class of outstanding
Common Stock or other voting securities is fair to the holders thereof, (F)
states that the offeror has obtained written financing commitments from
recognized financing sources, and/or has on hand cash or cash equivalents,
sufficient to consummate the tender offer, and (G) causes the offeror to be
the owner of 80% or more of the Company's outstanding Common Stock and other
voting securities); or (ii) a person becomes an Adverse Person, proper
provision shall be made so that each holder of a Right (other than Rights
beneficially owned by the Acquiring Person or Adverse Person and their
respective associates and affiliates, which will thereafter be void), will
thereafter have the right to receive, upon exercise thereof, at a price
equal to the then current Purchase Price multiplied by the number of one-
hundredths of a Preferred Share for which a Right is then exercisable, and
in lieu of Preferred Shares, that number of Common Shares having a market
value of two times the exercise price of such Right.

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

At any time after a person becomes an Acquiring Person, but before any
Acquiring Person or Adverse Person acquires 50% or more of the outstanding
                                       -4-
<PAGE>

Common Shares, the Board of Directors of the Company may exchange the Rights
(other than Rights owned by such Acquiring Person or group which have become
void), in whole or in part, for Common Stock or Preferred Stock of the
Company at an exchange ratio of one Common Share (or 1/100 of a Preferred
Share) per Right, subject to adjustment as provided in the Rights Plan.

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

At any time before the earlier of (i) the tenth day following the date on
which any Acquiring Person (or the Company) announces that such Acquiring
Person has obtained 15% or more of the Company's outstanding Common Stock,
(ii) the tenth day fol lowing the date on which any person becomes an
Adverse Person, (iii) such later date as the Board of Directors, or any
authorized committee of the Board, may designate (if it does so before the
time periods specified above have expired), or (iv) the Final Expiration
Date, the Board of Directors of the Company may redeem all, but not less
than all, of the then outstanding Rights at a price (subject to adjustment)
of $.001 per Right, rounded upward for each holder to the nearest whole cent
(the "'Redemption Price"), payable in cash or in Common Shares at the
discretion of the Board of Directors.  The redemption of the Rights may be
made effective at such time, on such basis and with such condition as the
Board of Directors in its sole discretion may establish.  Immediately upon
any redemption of the Rights, the right to exercise the Rights will 
automatically terminate and the only right of the holders of Rights will be
to receive the Redemption Price.

The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights.  As part of its
power to amend the Rights Plan, the Board may, at any time before a person
becomes an Acquiring Person or an Adverse Person, lower the threshold for
exercisability of the Rights from 15% to not less than the greater of (i)
11% or (ii) any percentage greater than the largest percentage of the out-
standing Common Shares then known to the Company to be beneficially owned by
any person or group of affiliated or associated persons (other than the
Company or any of its subsidiaries, any employee benefit plan of the Company
or any of its subsidiaries or any entity holding Common Shares for or
pursuant to any such plan).  From and after such time as any person becomes
an Acquiring Person or an Adverse Person, however, no amendment may be made
which would adversely affect the interests of the holders of the Rights
(other than an Acquiring or Adverse Person or their affiliates or associates).

Until a Right is exercised, the holder thereof, as such, will have no rights
as a shareholder of the Company, including, without limitation, the right to
vote or to receive dividends.  While the distribution of the Rights will not
                                    -5-
<PAGE>

be taxable to the Company's shareholders or to the Company itself, the share-
holders may, depending on the circumstances, recognize taxable income in the
event that the Rights become exercisable for Common Stock of the Company or
for common stock of the acquiring company, as set forth above.

One Right will be distributed on March 10, 1998 to shareholders of the
Company for each Common Share owned of record by them on March 3, 1998.
Until the Distribution Date, the Company will issue one Right with each
Common Share that shall become outstanding so that all Common Shares will
have attached Rights.  As of March 3, 1998, there were 7,190,710 Common
Shares issued and outstanding.  Also as of March 3, 1998, there were
1,290,800 Common Shares reserved for issuance in connection with, management
incentive plans and prior acquisitions.

The Rights have certain anti-takeover effects.  The Rights may cause
substantial dilution to a person or group that attempts to acquire the
Company on terms not approved by the Board of Directors of the Company,
and under certain circumstances the Rights beneficially owned by such a
person or group may become void.  The Rights should not interfere with any
merger or other business combination approved by the Board of  Directors
prior to the time that a person or group has become an Acquiring Person,
since prior to that time the Rights may be redeemed by the Company at $.001
per Right.

The present distribution of the Rights is not taxable to the Company or its
shareholders.  The Rights are not dilutive and will not affect reported
earnings per share.  The Company will receive no proceeds from the issuance
of the Rights as a dividend.

                             RIGHTS AGREEMENT


     THIS AGREEMENT, dated as of March 3, 1998, between HEMACARE CORPORATION, 
a California corporation (the "Company"), and U.S. STOCK TRANSFER CORPORATION
(the "Rights Agent").

     The Board of Directors of the Company has authorized and declared a 
dividend to be distributed on March 10, 1998 of one preferred share purchase 
right (a "Right") for each Common Share (as hereinafter defined) of the 
Company outstanding at the close of business (as hereinafter defined) on March 
3, 1998 (the "Record Date"), each Right representing the right to purchase 
one-hundredth of a Preferred Share (as hereinafter defined), upon the terms 
and subject to the conditions herein set forth, and has further authorized and 
directed the issuance of one Right with respect to each Common Share that 
shall become outstanding between the Record Date and the earliest of the 
Distribution Date, the Redemption Date and the Final Expiration Date (as such 
terms are hereinafter defined).

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

     Section 1.     CERTAIN DEFINITIONS.  For purposes of this Agreement, the 
following terms have the meanings indicated:
          
     (a)     "Acquiring Person" shall mean any Person (as such term is 
hereinafter defined) who or which, together with all Affiliates and Associates 
(as such terms are hereinafter defined) of such Person, shall be the 
Beneficial Owner (as such term is hereinafter defined) of 15% or more of the 
Common Shares of the Company then outstanding, but shall not include the 
Company, any Subsidiary (as such term is hereinafter defined) of the Company, 
any employee benefit plan of the Company or 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 become an "Acquiring 
Person" as the result of an acquisition of Common Shares by the Company which, 
by reducing the number of shares outstanding, increases the proportionate 
number of shares beneficially owned by such Person to 15% or more of the 
Common Shares of the Company then outstanding; provided, however, that if a 
Person (other than the Company, any Subsidiary of the Company, any employee 
benefit plan of the Company or any Subsidiary or any entity holding Common 
Shares for or pursuant to the terms of any such plan) 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, then such Person shall be deemed to be an 
"Acquiring Person."

     (b)     "Adverse Person" shall have the meaning set forth in Section 
11(a)(ii)(B) hereof.

     (c)     "Affiliate" and "Associate" shall have the respective meanings

under the Exchange Act (as hereinafter defined), 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 Regulation 13D-G 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 with and between 
underwriters and selling group members with respect to a bona fide public 

                                    -2-

provided, however, that a Person shall not be deemed the Beneficial Owner of, 
or to beneficially own, securities tendered pursuant to a tender or exchange 
offer made by or on behalf of such Person or any of such Person's Affiliates 
or Associates until such tendered securities are accepted for purchase or 
exchange; or (B) the right to vote pursuant to any agreement, arrangement or 
understanding; provided, however, that a Person shall not be deemed the 
Beneficial owner of, or to beneficially own, any security if the agreement, 
arrangement or understanding to vote such security (1) arises solely from a 
revocable proxy or consent given to such Person in response to a public proxy 
or consent solicitation made pursuant to, and in accordance with, the 
applicable rules and regulations promulgated under the Exchange Act, and (2) 
is not also then reportable on Schedule 13D or 13G 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 (other than customary agreements with and between 
underwriters and selling group members with respect to a bona fide public 
offering of securities), whether or not in writing, for the purpose of 
acquiring, holding, voting (except to the extent contemplated by the proviso 
to Section l(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 to be the Beneficial Owner of any securities (A) beneficially owned 
by another officer or director of the Company solely by reason of actions 
taken by such individual in his or her capacity as an officer or director of 
the Company, or (B) 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 a 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 such plan.

the contrary, the phrase "then outstanding," when used with reference to a 
Person's Beneficial Ownership of securities of the Company, shall mean the 
number of such securities then issued and outstanding together with the number 
of such securities not then actually issued and outstanding which such Person 
would be deemed to own beneficially hereunder.

     (f)     "Close of business" on any given date shall mean 5:00 P.M., Los 
Angeles time, on such date; provided, however, that if such date is not a 
Business Day it shall mean 5:00 P.M., Los Angeles time, on the next succeeding 
Business Day.

     (g)     "Common Shares" when used with reference to the Company shall 
mean the shares of common stock, without par value, of the Company.  "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.

     (h)     "Distribution Date" shall have the meaning set forth in Section 3 
hereof.

     (i)     "Excepted Tender Offer" shall mean a tender offer, made in the

or series of Voting Stock pursuant to such tender offer is fair to such 
holders;

     (D)     States that such Person has obtained written financing 
commitments from recognized financing sources, and/or has on hand cash or cash

     Section 3.     ISSUE OF RIGHT CERTIFICATES.

     (a)     Until the earlier of:

          (i)     the close of business on the tenth day after the Shares 
Acquisition Date;

          (ii)     the close of business on the tenth business day after the 
date of the commencement by any Person (other than the Company any Subsidiary 
of the Company, any employee benefit plan of the Company or of any Subsidiary 
of the Company or any entity holding Common Shares for or pursuant to the 
terms of any such plan) of, or of the first public announcement of the 
intention of any Person (other than the Company, any Subsidiary of the 
Company, any employee benefit plan of the Company or of any Subsidiary of the 
Company or any entity holding Common Shares for or pursuant to the terms of 
any such plan) to commence, a tender or exchange offer the consummation of 
which would result in any Person becoming the Beneficial Owner of Common 
Shares aggregating 15% or more of the then outstanding Common Shares;

          (iii)     the close of business on the tenth day after any Person 
becomes an Adverse Person pursuant to the criteria set forth in Section 
11(a)(ii)(B), below; or

          (iv)     with respect to the dates described in subsections (i) and 
(ii), above, such later date or dates as the Board of Directors may designate, 
provided, that if a later date or dates are so designated, such designation 
shall be made on or prior to the earlier of the dates specified in subsections 
(i) or (ii), above;

(including any such date which is after the date of this Agreement and prior 
to the issuance of the Rights), the earliest of the dates specified in 
subsections (i), (ii), (iii), and (iv) above being herein referred to as the 
"Distribution Date," (A) the Rights will be evidenced (subject to the 
provisions of Section 3(b) hereof) by the certificates for Common Shares 
registered in the names of the holders thereof (which certificates shall also 
be deemed to be Right Certificates) and not by separate Right Certificates, 
and (B) the right to receive Right Certificates will be transferable only in 
connection with the transfer of Common Shares.  As soon as practicable after 
the Distribution Date, the Company will prepare and execute, the Rights Agent 
will, upon request, countersign, and the Company will send or cause to be sent 
(and the Rights Agent will, if requested, send) by first-class, insured, 
postage-prepaid mail, to each record holder of Common Shares as of the close 
of business on the Distribution Date at the address of such holder shown on 
the records of the Company, one or more Right Certificates, in substantially 
the form of Exhibit B hereto (a "Right Certifi-
                                      -6-

<PAGE>

cate"), evidencing one Right for each Common Share so held subject to
adjustment as provided herein.  As of and after the Distribution Date, the
Rights will be evidenced solely by such Right Certificates.

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

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

                  This certificate also evidences and entitles the holder
                  hereof to certain rights as set forth in a Rights
                  Agreement between HemaCare Corporation and U.S. Stock
                  Transfer Corporation, dated as of March 3,1998 (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 HemaCare 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.  HemaCare Corporation will mail to the
                  holder of this certificate a copy of the Rights Agreement
                  without charge after receipt of a written request therefor.
                  As described in the Rights Agreement, under certain
                  circumstances Rights issued to any Person who becomes
                  an Acquiring Person or an Adverse Person or any Affiliate
                  or Associate
                                            -7-
<PAGE>
                  thereof (as such terms are defined in the
                  Rights Agreement) shall become null and void.

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

     Section 4.     FORM OF RIGHT CERTIFICATES.  The Right Certificates (and 
the forms of election to purchase Preferred Shares and of assignment to be 
printed on the reverse thereof) shall be substantially the same as Exhibit B 
hereto and may have such marks of identification or designation and such 
legends, summaries or endorsements printed thereon as the Company may deem 
appropriate and as are not inconsistent with the provisions of this Agreement, 
or as may be required to comply with any applicable law or with any rule or 
regulation made pursuant thereto or with any rule or regulation of any stock 
exchange on which the Rights may from time to time be listed, or to conform to 
usage.  Subject to the provisions of Sections 11 and 22 hereof, the Right 
Certificates shall entitle the holders thereof to purchase such number of 
one-hundredths of a Preferred Share as shall be set forth therein at the price 
per one-hundredth of a Preferred Share set forth therein (the "Purchase 
Price"), but the number of such one-hundredths of a Preferred Share and the 
Purchase Price shall be subject to adjustment as provided herein.

     Section 5.     COUNTERSIGNATURE AND REGISTRATION.

     (a)     The Right Certificates shall be executed on behalf of the Company 
by its Chairman of the Board, its President, its Vice Chairman of the Board, 
or any of its Vice Presidents, either manually or by facsimile signature, 
shall have affixed thereto the Company's seal or a facsimile thereof, and 
shall be attested by the Secretary or an Assistant Secretary of the Company, 
either manually or by facsimile signature.  The Right Certificates shall be 
manually countersigned by the Rights Agent and shall not be valid for any 
purpose unless countersigned.  In case any officer of the Company who shall 
have signed any of the Right Certificates shall cease to be such officer of 
the Company before countersignature by the Rights Agent and issuance and 
delivery by the Company, such Right Certificates, nevertheless, may be 
countersigned by the Rights Agent and issued and delivered by the Com-

                                  -8-
<PAGE>

pany with the same force and effect as though the person who signed such
Right Certificates had not ceased to be such officer of the Company; and
any Right Certificate may be signed on behalf of the Company by any person
who, at the actual date of the execution of such Right Certificate, shall
be a proper officer of the Company to sign such Right Certificate, although
at the date of the execution of this 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 Right Certificates issued hereunder.  Such 
books shall show the names and addresses of the respective holders of the 
Right Certificates, the number of Rights evidenced on its face by each of the 
Right Certificates and the date of each of the Right Certificates.

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

     (a)     Subject to the provisions of Section 14 hereof, at any time after 
the close of business on the Distribution Date, and at or prior to the close 
of business on the earlier of the Redemption Date or the Final Expiration 
Date, any Right Certificate or Right Certificates (other than Right 
Certificates representing Rights that have become void pursuant to Section 
11(a)(ii) hereof or that have been exchanged pursuant to Section 24 hereof) 
may be transferred, split up, combined or exchanged for another Right 
Certificate or Right Certificates, entitling the registered holder to purchase 
a like number of one-hundredths of a Preferred Share (or other securities) as 
the Right Certificate or Right Certificates surrendered then entitled such 
holder to purchase.  Any registered holder desiring to transfer, split up, 
combine or exchange any Right Certificate or Right Certificates shall make 
such request in writing delivered to the Rights Agent, and shall surrender the 
Right certificate or Right Certificates to be transferred, split up, combined 
or exchanged at the office of the Rights Agent designated for such purpose; 
provided, however, that in the case of any transfer or assignment of all or 
part of a Right Certificate, neither the Company nor the Rights Agent shall be 
obligated to take any action whatsoever with respect to such a request until 
the registered holder of the Right Certificate shall have completed and signed 
the certificate contained in the form of assignment on the reverse side 
thereof and shall have provided such additional evidence as to the identity of 
the Beneficial Owner (or former Beneficial Owner), and/or the Affiliates or 
Associates thereof, as the Company shall reasonably request.  Thereupon the 
Company will prepare and execute, and the Rights Agent will countersign and 
deliver to the person entitled thereto, a Right Certificate or Right 
Certificates, as the case may be, as so requested.  The Company or the Rights 
Agent may require
                                    -9-

<PAGE>

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

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

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

     (a)     The registered holder of any Right Certificate may exercise the 
Rights evidenced thereby (except as otherwise provided herein) in whole or in 
part at any time after the Distribution Date upon surrender of the Right 
Certificate, with the form of election to purchase on the reverse side thereof 
duly executed, to the Rights Agent at the office of the Rights Agent 
designated for such purpose, together with payment of the Purchase Price for 
each one-hundredth of a Preferred Share as to which the Rights are exercised,

pursuant to the exercise of a Right shall initially be $5.00, 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 Right Certificate representing exercisable 
Rights, with the form of election to purchase duly executed, accompanied by 
payment of the Purchase Price for the shares (or other securities or property, 
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 Right Certificate in 
accordance with Section 9 hereof in cash, or by certified check, cashier's 
check, bank draft or money order payable to the order of the Company, the 
Rights Agent shall thereupon promptly (i) (A) requisition from any transfer 
agent of the Preferred

                                    -10-
<PAGE>

Shares certificates for the number of Preferred Shares
to be purchased (and the Company hereby irrevocably authorizes its transfer 
agent to comply with all such requests), or (B) requisition from the 
depositary agent depositary receipts representing such number of 
one-hundredths of a Preferred Share as are to be purchased (in which case 
certificates for the Preferred Shares represented by such receipts shall be 
deposited by the transfer agent with the depositary agent), and the Company 
hereby directs the depositary agent to comply with such request, (ii) when 
appropriate, requisition from the Company the amount of cash to be paid in 
lieu of issuance of fractional shares in accordance with Section 14 hereof, 
(iii) after receipt of such certificates or depositary receipts, cause the 
same to be delivered to or upon the order of the registered holder of such 
Right Certificate, registered in such name or names as may be designated by 
such holder and (iv) when appropriate, after receipt thereof, deliver such 
cash to or upon the order of the registered holder of such Right Certificate.

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

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

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

                                      -11-

of the Company, destroy such canceled Right Certificates, and in such case
shall deliver a certificate of destruction thereof to the Company.

     Section 9.     AVAILABILITY OF COMMON AND PREFERRED SHARES.

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

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

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

     Section 10.     PREFERRED OR COMMON SHARES RECORD DATE.  Each Person in 
whose name any certificate for Preferred Shares or Common Shares is issued 
upon the exercise of Rights shall for all purposes be deemed to have become 
the holder of record of the Preferred Shares or Common Shares represented 
thereby on, and such certificate shall be dated, the date upon which the Right 
Certificate evidencing such Rights was duly surrendered with the election form 
duly executed and payment of the Purchase Price (and any applicable transfer 
taxes) was made; PROVIDED, HOWEVER, that if the date of such surrender and 
payment is a date upon which the Preferred or Common Share transfer books of 
the Company are closed, such person shall be deemed to have become the record

                                    -12-

<PAGE>

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 Right 
Certificate shall not be entitled to any rights of a holder of Preferred or 
Common Shares for which the Rights shall be exercisable, including, without 
limitation, the right to vote, to receive dividends or other distributions, or 
to exercise any preemptive rights, and such holder shall not be entitled to 
receive any notice of any proceedings of the Company, except as provided 
herein.

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

     (a)     (i) In the event the Company shall at any time after the date of 
this Agreement (A) declare a dividend on the Preferred Shares payable in 
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine 
the outstanding Preferred Shares into a smaller number of Preferred Shares or 
(D) issue any shares of its capital stock in a reclassification of the 
Preferred Shares (including any such reclassification in connection with a 
consolidation or merger in which the Company is the continuing or surviving 
corporation), except as otherwise provided in this Section 11(a), the Purchase 
Price in effect at the time of the record date for such dividend or of the 
effective date of such subdivision, combination or reclassification, and the 
number and kind of shares of capital stock issuable on such date, shall be 
proportionately adjusted so that the holder of any Right exercised after such 
time shall be entitled to receive, upon payment of the Purchase Price then in 
effect, the aggregate number and kind of shares of capital stock which, if 
such Right had been exercised immediately prior to such date and at a time 
when the Preferred Shares transfer books of the Company were open, he would 
have owned upon such exercise and been entitled to receive by virtue of such 
dividend, subdivision, combination or reclassification.  If an event occurs 
which would require an adjustment under both this Section 11(a)(i) and Section 
11(a)(ii), below, the adjustment provided for in this Section 11(a)(i) shall 
be in addition to, and shall be made prior to, any adjustment required 
pursuant to Section 11(a)(ii), below.
 
          (ii)     Subject to Section 24 of this Agreement, in the event that

     (A)     any Person shall become an Acquiring Person (other than through 
an acquisition described in subparagraph (iii) of this paragraph (a)); or

                                       -13
<PAGE>

     (B)     (1) the Board of Directors shall designate a specific limitation
on the amount of Common Shares which a specified Person may beneficially own, 
which amount (the "Ownership Limitation") may be less than, equal to or more 
than the amount of Common Shares then owned by such Person, but shall in no 
event be less than 11% of the then outstanding Common Shares of the Company, 
(2) at least a majority of the Board of Directors who are not officers of the 
Company and who are not representatives, nominees, Affiliates or Associates of 
such Person, after reasonable inquiry and investigation, including 
consultation with such persons as such directors shall deem appropriate, shall 
(x) conclude that Beneficial Ownership by such Person of an amount of Common 
Shares exceeding the Ownership Limitation is, or would likely be, intended to 
cause the Company to repurchase the Common Shares beneficially owned by such 
Person or to cause pressure on the Company to take action or enter into a 
transaction or series of transactions intended to provide such Person with 
short-term financial gain under circumstances where the Board of Directors 
determines that the best long-term interests of the Company and its 
shareholders would not be served by taking such action or entering into such 
transactions or series of transactions at that time, or (y) determine that 
Beneficial Ownership by such Person of an amount of Common Shares exceeding 
the Ownership Limitation is causing or reasonably likely to cause a material 
adverse impact (including, but not limited to, impairment of relationships 
with customers or impairment of the Company's ability to maintain its 
competitive position) on the business or prospects of the Company, and (3) 
such Person, together with its Affiliates and Associates shall (before or 
after the occurrence of (1) and (2) above) beneficially own a number of shares 
that exceeds the Ownership Limitation (any person meeting all of the criteria 
set forth in this subparagraph (B) being an "Adverse Person");

then, following the first occurrence of either such event, each holder of a 
Right (except as provided below) shall thereafter have a right to receive, 
upon exercise thereof at a price equal to the then current Purchase Price 
multiplied by the number of one-hundredths of a Preferred Share for which a 
Right is then exercisable, in accordance with the terms of this Agreement and 
in lieu of Preferred Shares, such number of Common Shares of the Company as 
shall equal the result obtained by (x) multiplying the then current Purchase 
Price by the number of one-hundredths of a Preferred Share for which a Right 
is then exercisable and dividing that product by (y) 50% of the then current 
per share market price of the Company's Common Shares (determined pursuant to 
Section 11(d) hereof) on the date of the first to occur of the events 
described in clauses (A) or (B), above.  In the event that any Person shall 
become an Acquiring Person and the Rights shall then be outstanding, the 
Company shall not take any action which

                                    -14-

<PAGE>

would eliminate or diminish the benefits intended to be afforded by the
Rights.

     From and after the occurrence of any of the events described in clauses 
(A) or (B), above, any Rights that are or were acquired or beneficially owned 
by such Acquiring Person or Adverse Person (or any Associate or Affiliate of 
such Acquiring Person or Adverse Person) shall be void, and any holder of such 
Rights shall thereafter have no right to exercise such Rights under any 
provision of this Agreement.  No Right Certificate shall be issued pursuant to 
Section 3 that represents Rights beneficially owned by an Acquiring Person or 
Adverse Person whose Rights would be void pursuant to the preceding sentence, 
or any Associate or Affiliate thereof; no Right Certificate shall be issued at 
any time upon the transfer of any Rights to an Acquiring Person or Adverse 
Person whose Rights would be void pursuant to the preceding sentence, or any 
Associate or Affiliate thereof, or to any nominee of such Acquiring Person or 
Adverse Person, or his or its Associates or Affiliates; and any Right 
Certificate delivered to the Rights Agent for transfer to an Acquiring Person 
or Adverse Person (or any Associate, Affiliate or nominee thereof) whose 
Rights would be void pursuant to the preceding sentence shall be canceled.

          (iii)  The right to buy Common Shares of the Company pursuant to 
subparagraph (ii) of this paragraph (a) shall not arise as a result of any 
Person becoming an Acquiring Person through a purchase of Common Shares 
pursuant to an Excepted Tender Offer.

          (iv)  In the event that there shall not be sufficient Common Shares 
issued but not outstanding or authorized but unissued to permit the exercise 
in full of the Rights in accordance with the foregoing subparagraph (ii), the 
Company shall take all such action as may be necessary to authorize additional 
Common Shares for issuance upon exercise of the Rights.

     (b)     In case the Company shall fix a record date for the issuance of 
rights, options or warrants to all holders of Preferred Shares entitling them 
(for a period expiring within 45 calendar days after such record date) to 
subscribe for or purchase Preferred Shares (or shares having the same rights, 
privileges and preferences as the Preferred Shares) ("equivalent preferred 
shares") or securities convertible into Preferred Shares or equivalent 
preferred shares, at a price per Preferred Share or equivalent preferred share 
(or having a conversion price per share, if a security convertible into 
Preferred Shares or equivalent preferred shares) less than the then current 
per share market price of the Preferred Shares (as defined in Section 11(d)) 
on such record date, the Purchase Price to be in effect after such record date 
shall be determined by multiplying the Purchase Price in effect immediately 
prior to such record date by

                                      -15-
<PAGE>


a fraction, the numerator of which shall be the number of Preferred Shares
outstanding on such record date plus the number of Preferred Shares which
the aggregate offering price of the total number of Preferred Shares and/or
equivalent preferred shares so to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would
purchase at such current market price and the denominator of which shall be
the number of Preferred Shares outstanding on such record date plus the
number of additional Preferred Shares and/or equivalent preferred shares to
be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible).  In case
such subscription price may be paid in a consideration part or all of which 
shall be in a form other than cash, the value of such consideration shall be 
as determined in good faith by the Board of Directors of the Company, whose 
determination shall be described in a statement filed with the Rights Agent.  
Preferred Shares owned by or held for the account of the Company shall not be 
deemed outstanding for the purpose of any such computation.  Such adjustments 
shall be made successively whenever such a record date is fixed; and in the 
event that such rights, options or warrants are not so issued, the Purchase 
Price shall be adjusted to be the Purchase Price which would then be in effect 
if such record date had not been fixed.

     (c)     In case the Company shall fix a record date for the making of a 
distribution to all holders of the Preferred Shares (including any such 
distribution made in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation) of evidences of 
indebtedness or assets (other than a regular quarterly cash dividend or a 
dividend payable in Preferred Shares) or subscription rights or warrants 
(excluding those referred to in Section 11(b) hereof), the Purchase Price to 
be in effect after such record date shall be determined by multiplying the 
Purchase Price in effect immediately prior to such record date by a fraction, 
the numerator of which shall be the then current per share market price of the 
Preferred Shares (as defined in Section 11(d), below) on such record date, 
less the fair market value (as determined in good faith by the Board of 
Directors of the Company, whose determination shall be described in a 
statement filed with the Rights Agent) of the portion of the assets or 
evidences of indebtedness so to be distributed or of such subscription rights 
or warrants applicable to one Preferred Share and the denominator of which 
shall be such current per share market price of the Preferred Shares.  Such 
adjustments shall be made successively whenever such a record date is fixed; 
and in the event that such distribution is not so made, the Purchase Price 
shall again be adjusted to be the Purchase Price which would then be in effect 
if such record date had not been fixed.

     (d)     (i) For the purpose of any computation hereunder, the "current 
per share market price" of any security (a "Security"

                                   -16-

<PAGE>

for the purpose of this Section 11(d)(i)) on any date shall be deemed to be the
average of the daily closing prices per share of such Security for the 30
consecutive Trading Days (as such term is hereinafter defined) immediately
prior to such date; provided, however, that in the event that the current
per share market price of the Security is determined during a period
following the announcement by the issuer of such Security of (A) a dividend
or distribution on such Security payable in shares of such Security or
securities convertible into such shares, or (B) any subdivision, combination
or reclassification of such Security, and prior to the expiration of 30
Trading Days after the ex-dividend date for such dividend or distribution, or
the record date for such subdivision, combination or reclassification, then,
and in each such case, the current per share market price shall be appropriately
adjusted to reflect the current market price per share equivalent of such
Security.  The closing price for each day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average
of the closing bid and asked prices, regular way, in either case as reported
in the principal consolidated transaction reporting system with respect to
securities listed or admitted to trading on the New York Stock Exchange or,
if the security is not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting
system with respect to securities listed on the principal national securities
exchange on which the Security is listed or admitted to trading or, if the
Security is not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the
high bid and low asked prices in the over-the-counter market, as reported
by the National Association of Securities Dealers, Inc.  Automated Quotations
System ("NASDAQ") or such other system then in use, or, if on any such date
the Security is not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker
making a market in the Security selected by the Board of Directors of the
Company, or, if on any such date no market maker is making a market in the 
Preferred Shares, 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.  The term 
"Trading Day" shall mean a day on which the principal national securities 
exchange on which the Security is listed or admitted to trading is open for 
the transaction of business or, if the Security is not listed or admitted to 
trading on any national securities exchange, a Business Day.

          (ii)  For the purpose of any computation hereunder, the "current per 
share market price" of the Preferred Shares shall be determined in accordance 
with the method set forth in Section 11(d)(i).  If the Preferred Shares are 
not publicly traded, the "current per share market price" of the Preferred 
Shares shall be conclusively deemed to be the current per share market price 
of the Common Shares as determined pursuant to Section 11(d)(i)

                                   -17-

<PAGE>

(appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof), multiplied by 100.  If neither
the Common Shares nor the Preferred Shares are publicly held or so listed
or traded, "current per share market price" shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent.

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

     (f)     If, as a result of an adjustment made pursuant to Section 11(a) 
or 13(a) hereof, the holder of any Right thereafter exercised shall become 
entitled to receive any shares of capital stock of the Company other than 
Preferred Shares, thereafter the number of such other shares so receivable 
upon exercise of any Right shall be subject to adjustment from time to time in 
a manner and on terms as nearly equivalent as practicable to the provisions 
with respect to the Preferred Shares contained in Section 11(a) through (c), 
inclusive, 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.

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

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

                                   -18-
<PAGE>

adjustment by (B) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by 
the Purchase Price in effect immediately after such adjustment of the Purchase 
Price.

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

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


                                        -19-
<PAGE>

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

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

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

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

                                      -20-

<PAGE>

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

     (o)     Any failure by the Company's Board of Directors to take steps to 
declare a Person to be an Adverse Person following the date on which such 
Person (alone or together with its Affiliates and Associates) becomes the 
Beneficial owner of an amount of Common Shares in excess of the Ownership 
Limitation shall not limit the Board's right or authority to declare such 
Person to be an Adverse Person at any time in the future.

     Section 12.     CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF 
SHARES.  Whenever an adjustment is made as provided in Sections 11 and 13 
hereof, the Company shall promptly (a) prepare a certificate setting forth 
such adjustment and a brief statement of the facts accounting for such 
adjustment, (b) file with the Rights Agent and with each transfer agent for 
the Common Shares or the Preferred Shares a copy of such certificate, and (c) 
mail a brief summary thereof to each holder of a Right Certificate in 
accordance with Section 25 hereof.  Notwithstanding the foregoing sentence, 
however, the failure of the Company to make such certification or give such 
notice shall not affect the validity of any such adjustment, or the force and 
effect of any requirement therefor.

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

     (a)     In the event that, after the Shares Acquisition Date, directly or 
indirectly,

          (i)     the Company shall consolidate with, or merge with and into, 
any other Person (other than a Subsidiary of the Company in a transaction the 
principal purpose of which is to change the Company's state of incorporation),

          (ii)     any Person (other than a Subsidiary of the Company in a 
transaction the principal purpose of which is to change the Company's state of 
incorporation) 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 consolidation or 
merger, all or part of the outstanding Common Shares shall be changed into or 
exchanged for stock or other securities of any other Person (or the Company) 
or cash or any other property, or

                                     -21-
<PAGE>

          (iii)     the Company shall sell or otherwise transfer (or one or 
more of its Subsidiaries shall sell or otherwise transfer), in one transaction 
or a series of related transactions, assets or earning power aggregating 50% 
or more of the assets or earning power of the Company and its Subsidiaries 
(taken as a whole) to any other Person other than the Company or one or more 
of its wholly-owned subsidiaries;

then, and in each such case, proper provision shall be made so that (A) each 
holder of a Right (except as otherwise provided herein) shall thereafter have 
the right to receive, upon the exercise thereof at a price equal to the then
current Purchase Price multiplied by the number of one-hundredths of a Preferred
Share for which a Right is then exercisable, in accordance with the terms of
this Agreement and in lieu of Preferred Shares, such number of validly
authorized and issued, fully paid and nonassessable Common Shares of such
other Person (including the Company as successor thereto or as the surviving
corporation), not subject to any liens, encumbrances, rights of first refusal
or other adverse claims, as shall equal the result obtained by (x) multiplying
the then current Purchase Price by the number of one-hundredths of a Preferred
Share for which a Right is then exercisable and dividing that product by (y)
50% of the then current per share market price of the Common Shares of such
other Person (determined pursuant to Section 11(d) hereof) on the date of
consummation of such consolidation, merger, sale or transfer; (B) the issuer
of such Common Shares shall thereafter be liable for, and shall assume, by
virtue of such consolidation, merger, sale or transfer, all the obligations
and duties of the Company pursuant to this Agreement; (C) the term "Company"
shall thereafter be deemed to refer to such issuer; and (D) such issuer shall
take such steps (including, but not limited to, the reservation of a
sufficient number of its Common Shares) in connection with such consummation
as may be necessary to assure that the provisions hereof shall thereafter be
applicable, as nearly as reasonably may be, in relation to the Common Shares
thereafter deliverable upon the exercise of the Rights.

     (b)     The Company shall not consummate any transactions of the type 
referred to in Section 13(a), above, unless (i) prior thereto the Company and 
such issuer shall have executed and delivered to the Rights Agent a 
supplemental agreement so providing; (ii) at the time of such transaction such 
issuer has no rights, warrants, instruments or securities outstanding, and has 
entered into no 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 (iii) such issuer 
shall have a sufficient number of authorized Common Shares which have not been 
issued or reserved for issuance to permit the exercise in full of the Rights 
in accordance with this Section 13.  The provisions of this Section

                                    -22-
<PAGE>

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

     (b)     The Company shall not be required to issue fractions of Preferred 
Shares (other than fractions which are integral multiples of one one-hundredth 
of a Preferred Share) upon exercise of the Rights or to distribute 
certificates which evidence fractional Preferred Shares (other than fractions 
which are integral multiples of one one-hundredth of a Preferred Share).  
Fractions of Preferred Shares in integral multiples of one one-hundredth of a 
Preferred Share may, at the election of the Company, be evidenced by 
depositary receipts, pursuant to an appropriate agreement between the Company 
and a depositary selected by it; PROVIDED, HOWEVER, 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

                                    -23-
<PAGE>

owners of the Preferred Shares represented by such depositary receipts.  In 
lieu of fractional Preferred Shares that are not integral multiples of one 
one-hundredth of a Preferred Share, the Company shall pay to the registered 
holders of Right Certificates at the time such Rights are exercised as herein 
provided an amount in cash equal to the same fraction of the current market 
value of one Preferred Share.  For the purposes of this Section 14(b), the 
current market value of a Preferred Share shall be the closing price of a 
Preferred Share (as determined pursuant to the second sentence of Section 
11(d)(i) hereof) for the Trading Day immediately prior to the date of such 
exercise.

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

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

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

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

     (b)     after the Distribution Date, the Right Certificates are 
transferable only on the registry books of the Rights Agent if surrendered at 
the office of the Rights Agent maintained for such

                                    -24-
<PAGE>


purpose, duly endorsed or accompanied by a proper instrument of transfer;
and

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

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

     Section 18.     CONCERNING THE RIGHTS AGENT.

     (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 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.

     (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 
Right Certificate or certificate for the Preferred Shares or Common Shares or 
for other securities
                                   -25-

of the Company, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by 
the proper person or persons, or otherwise upon the advice of counsel as set 
forth in Section 20 hereof.

     (c)     The obligations of the Company under this Section 18 shall 
survive the redemption, exchange or cancellation of the Right Certificates or 
the resignation or removal of the Rights Agent.

     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 stock transfer or corporate trust business of the Rights 
Agent or any successor Rights Agent, shall be the successor to the Rights 
Agent under this Agreement without the execution or filing of any paper or any 
further act on the part of any of the parties hereto, provided that such 
corporation would be eligible for appointment as a successor Rights Agent 
under the provisions of Section 21 hereof.  In case at the time such successor 
Rights Agent shall succeed to the agency created by this Agreement any of the 
Right Certificates shall have been countersigned but not delivered, any such 
successor Rights Agent may adopt the countersignature of the predecessor 
Rights Agent and deliver such Right Certificates so countersigned; and in case 
at that time any of the Right Certificates shall not have been countersigned, 
any successor Rights Agent may countersign such Right Certificates either in 
the name of the predecessor Rights Agent or in the name of the successor 
Rights Agent; and in all such cases such Right Certificates shall have the 
full force provided in the Right Certificates and in this Agreement.

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

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

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

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

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

     (e)     The Rights Agent shall not be under any responsibility in respect 
of the validity of this Agreement or the execution and delivery hereof (except 
the due execution hereof by the Rights Agent) or in respect of the validity or 
execution of any Right Certificate (except its countersignature thereof); nor 
shall it be responsible for any breach by the Company of any covenant or 
condition contained in this Agreement or in any Right Certificate; nor shall 
it be responsible for any change in the exercisability of the Rights 
(including the Rights becoming void pursuant to section 11(a)(ii) hereof) or 
any adjustment in the terms of the Rights (including the manner, method or 
amount thereof) provided for in Sections 3, 11, 13, 23 or 24, or the 
ascertaining of the existence of facts that would require any such change or 
adjustment (except with respect to the exercise of Rights evidenced by Right 
Certificates after actual notice that such change

                                    -27-
<PAGE>

or adjustment is required); nor shall it by any act hereunder be deemed to
make any representation or warranty as to the authorization or reservation
of any Preferred Shares to be issued pursuant to this Agreement or any
Right Certificate or as to whether any Preferred Shares will, when issued,
be validly authorized and issued, fully paid and nonassessable.

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

     (g)     The Rights Agent is hereby authorized and directed to accept 
instructions with respect to the performance of its duties hereunder from any 
one of the Chairman of the Board, the Vice Chairman of the Board, the 
President, any Vice President, the Secretary or the Chief Financial Officer 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.

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

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

     (j)     The Rights Agent shall be obligated to perform such duties and 
only such duties as are specifically set forth herein and in the Right 
Certificates and no implied duties or obligations (other than good faith and 
due care) shall be read into this Agreement or the Right Certificates.  
Without limiting the generality of the foregoing, the Rights Agent shall be 
under no duty to make any determination whether a supplement or amendment  to 
this Agreement, or any course of action proposed to be taken

                                    -28-
<PAGE>

by the Company, is or is not in the best interests of the holders of Right
Certificates or in any way affects or diminishes the benefits intended to be
afforded by the Rights.  The Rights Agent shall have no duty or responsibility
to the holders of Right Certificates in case of any default by the Company
in the performance of its covenants or agreements contained herein or in the
Right Certificates.

     Section 21.     CHANGE OF RIGHTS AGENT.  The Rights Agent or any 
successor Rights Agent may resign and be discharged from its duties under this 
Agreement upon 30 days notice in writing mailed to the Company and to each 
transfer agent of the Common Shares or Preferred Shares by registered or 
certified mail, and to the registered holders of the Right Certificates by 
first-class mail.  The Company may remove the Rights Agent or any successor 
Rights Agent upon 30 days notice in writing, mailed to the Rights Agent or 
successor Rights Agent, as the case may be, and to each transfer agent of the 
Common Shares or Preferred Shares by registered or certified mail, and to the 
registered holders of the Right Certificates by first-class mail.  If the 
Rights Agent shall resign or be removed or shall otherwise become incapable of 
acting, the Company shall appoint a successor to the Rights Agent.  If the 
Company shall fail to make such appointment within a period of 30 days after 
giving notice of such removal or after it has been notified in writing of such 
resignation or incapacity by the resigning or incapacitated Rights Agent or by 
the holder of a Right Certificate (who shall, with such notice, submit his 
Right Certificate for inspection by the Company), then the registered holder 
of any Right Certificate may apply to any court of competent jurisdiction for 
the appointment of a new Rights Agent.  Any successor Rights Agent, whether 
appointed by the Company or by such a court, shall be (a) a corporation 
organized and doing business under the laws of the United States or of the 
States of New York or California (or of any other state of the United States 
so long as such corporation is authorized to do business as a banking 
institution in the States of New York or California), in good standing, having 
an office in the States of New York or California, which is authorized under 
such laws to exercise corporate trust or stock transfer powers and is subject 
to supervision or examination by federal or state authority and which has at 
the time of its appointment as Rights Agent a combined capital and surplus of 
at least $50 million, or (b) an affiliate of a corporation described in clause 
(a) of this sentence.  After appointment, the successor Rights Agent shall be 
vested with the same powers, rights, duties and responsibilities as if it had 
been originally named as Rights Agent without further act or deed; but the 
predecessor
                                    -29-

<PAGE>

Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver 
any further assurance, conveyance, act or deed necessary for the purpose.  Not 
later than the effective date of any such appointment, the Company shall file 
notice thereof in writing with the predecessor Rights Agent and each transfer 
agent of the Common Shares or Preferred Shares, and mail a notice thereof in 
writing to the registered holders of the Right Certificates.  Failure to give 
any notice provided for in this Section 21, however, or any defect therein, 
shall not affect the legality or validity of the resignation or removal of the 
Rights Agent or the appointment of the successor Rights Agent, as the case may 
be.

     Section 22.     ISSUANCE OF NEW RIGHT CERTIFICATES.  Notwithstanding any 
of the provisions of this Agreement or of the Rights to the contrary, the 
Company may, at its option, issue new Right Certificates evidencing Rights in 
such form as may be approved by its Board of Directors to reflect any 
adjustment or change in the Purchase Price and the number or kind or class of 
shares or other securities or property purchasable under the Right 
Certificates made in accordance with the provisions of this Agreement.  If the 
Company determines to issue new Right Certificates pursuant to this Section 
22, the Company will prepare and execute and, upon request, the Rights Agent 
will countersign and deliver to the holders of Right Certificates such new 
Right Certificates.

     Section 23.     REDEMPTION.

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

     (b)     The Board of Directors of the Company may, at its option, redeem 
all but not less than all the then outstanding Rights at a redemption price of 
$.001 per Right (rounded upward for each holder to the nearest $.01), payable 
in cash or shares of Common Stock of the Company at the discretion of the 
Board of Directors, appropriately adjusted to reflect any stock split, stock 
dividend or similar transaction occurring after the date hereof (such 
redemption price being hereinafter referred to as the "Redemption Price"), at 
any time on or before the earlier of (i) the close of business on the tenth 
day following the Shares Acquisition Date (or, if the shares Acquisition Date 
shall have occurred prior to the Record Date, then the close of business on 
the tenth business day following the Record Date), (ii) the close of business 
on the tenth day following the date on which any Person becomes an Adverse 
Person, (iii) such later date or dates as the Board of Directors, or any duly 
authorized committee thereof, any designate (provided, however, that if such 
later date or dates are designated, such designation shall be made on or prior 
to the date by which redemption would otherwise be required), or (iv) the 
Final Expiration Date.  The redemption of the Rights by the Board of Directors 
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.
                                    -30-

<PAGE>

     (c)     Immediately upon the action of the Board of Directors of the 
Company ordering the redemption of the Rights pursuant to subsection (b) of 
this Section 23, 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 notice to the Rights Agent and public notice of any such 
redemption; provided, however, that the failure to give, or any defect in, any 
such notice shall not affect the validity of such redemption.  Within 10 
business days after such action of the Board of Directors ordering the 
redemption of the Rights pursuant to subsection (b), the Company shall mail a 
notice of redemption to all the holders of the then outstanding Rights at 
their last addresses as they appear upon the registry books of the Rights 
Agent or, prior to the Distribution Date, on the registry books of the 
transfer agent for the Common Shares.  Any notice which is mailed in the 
manner herein provided shall be deemed given, whether or not the holder 
receives the notice.  Each such notice of redemption will state the method by 
which the payment of the Redemption Price will be made.  Neither the company 
nor any of its Affiliates or Associates may redeem, acquire or purchase for 
value any Rights at any time in any manner other than that specifically set 
forth in this Section 23 or in Section 24 hereof, and other than in connection 
with the purchase of Common Shares prior to the Distribution Date.

     Section 24.     EXCHANGE.

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

     (b)     Immediately upon the action of the Board of Directors of the 
Company ordering the exchange of any Rights pursuant to subsection (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 promptly give notice to the
                                    -31-

<PAGE>

Rights Agent and 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 promptly 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 11(a)(ii) hereof) held by each holder
of Rights.

     (c)     In any exchange pursuant to this Section 24, the Company, at its 
option, may substitute Preferred Shares (or equivalent preferred shares, as 
such term is defined in section 11(b) hereof) for Common Shares exchangeable 
for Rights, at the initial rate of one one-hundredth of a Preferred Share (or 
equivalent preferred share) for each Common Share, as appropriately adjusted 
to reflect adjustments in the voting rights of the Preferred Shares pursuant 
to the terms thereof, so that the fraction of a Preferred Share delivered in 
lieu of each Common Share shall have the same voting rights as one Common 
Share.

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

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

     Section 25.     NOTICE OF CERTAIN EVENTS.

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

                SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                             (WITHOUT PAR VALUE)

                                     of

                             HEMACARE CORPORATION

                       (Pursuant to Section 401 of the
              General Corporation Law of the State of California)
                     _____________________________________


          The undersigned, being the Secretary of HemaCare Corporation, a 
corporation organized and existing under the General Corporation Law of the 
State of California (the "Company"), DOES HEREBY CERTIFY that the following 
resolution was adopted by the Board of Directors of the Company as required by 
Selection 401 of the General Corporation Law at a meeting duly called and held 
on February 23, 1998:

          RESOLVED, that pursuant to the authority expressly granted to and 
vested in the Board of Directors of this Company in accordance with the 
provisions of the Company's Articles of Incorporation, as amended (the 
"Articles of Incorporation"), this Board of Directors hereby authorizes the 
issuance of a series of the Serial Preferred Stock of the Company (the 
"Preferred Stock") which shall consist of 250,000 shares of the Company's 
Preferred Stock, and hereby fixes the powers, designations, preferences, and 
relative, participating, optional, or other special rights, and the 
qualifications, limitations, or restrictions thereof, of the shares of such 
series (in addition to the powers, designations, preferences, and relative, 
participating, optional or other special rights, and the qualifications, 
limitations, or restrictions thereof, set forth in the Articles of 
Incorporation of the Company which are applicable to the Preferred Stock) as 
follows:

          Series A Junior Participating Preferred Stock:

     Section 1.     Designation and Amount.  The shares of such series shall 
be designated as "Series A Junior Participating Preferred Stock" (the "Series 
A Preferred Stock") and the number of shares constituting the Series A 
Preferred Stock shall be 250,000.  Such number of shares may be increased or 
decreased by resolution of the Board of Directors; provided, however, that no 
decrease shall reduce the number of shares of Series A Preferred Stock to a 
number less than the number of shares then outstanding plus the number of 
shares reserved for issuance upon the exercise of outstanding options, rights, 
or warrants or upon the conversion of any outstanding securities issued by the 
Company convertible into Series A Preferred Stock.

     Section 2.     Dividends and Distributions.

          (a)     Subject to the rights of the holders of any shares of any 
series of Preferred Stock (or any similar stock) ranking prior and superior to 
the Series A Preferred Stock with respect to dividends, the holders of shares 
of Series A Preferred Stock, in preference to the holders of Common Stock, 
without par value (the "Common Stock"), of the Company, and of any other 
junior stock, shall be entitled to receive, when, as, and if declared by the 
Board of Directors out of funds legally available for the purpose, quarterly 
dividends payable in cash on  January 15, April 15, July 15, and October 15 of 
each year (each such date being referred to herein as a "Quarterly Dividend 
Payment Date"), commencing on the first Quarterly Dividend Payment Date after 
the first issuance of a share or fraction of a share of Series A Preferred 
Stock, in an amount per share (rounded to the nearest cent) equal to the 
greater of (a) $0.02 or (b) subject to the provision for adjustment 
hereinafter set forth, 100 times the aggregate per share amount (payable in 
kind) of all non-cash dividends or other distributions, other than a dividend 
payable in shares of Common Stock or a subdivision of the outstanding shares 
of Common Stock (by reclassification or otherwise), declared on the Common 
Stock since the immediately preceding Quarterly Dividend Payment Date or, with 
respect to the first Quarterly Dividend Payment Date, since the first issuance 
of any share or fraction of a share of Series A Preferred Stock.  In the event 
the Company shall at any time declare or pay any dividend on the Common Stock 
payable in shares of Common Stock, or effect a subdivision, combination, or 
consolidation of the outstanding shares of Common Stock (by reclassification 
or otherwise than by payment of a dividend in shares of Common Stock) into a 
greater or lesser number of shares of Common Stock, then in each such case the 
amount to which holders of shares of Series A Preferred Stock were entitled 
immediately prior to such event under clause (b) of the preceding sentence 
shall be adjusted by multiplying such amount by a fraction, the numerator of 
which is the number of shares of Common Stock outstanding immediately after 
such event and the denominator of which is the number of shares of Common 
Stock that were outstanding immediately prior to such event.

          (b)     The Company shall declare a dividend or distribution on the 
Series A Preferred Stock as provided in paragraph (a) of this Section 
immediately after it declares a dividend or distribution on the Common Stock 
(other than a dividend payable in shares of Common Stock); provided, however, 
that in the event no dividend or distribution shall have been declared on the 
Common Stock during the period between any Quarterly Dividend Payment Date and 
the next subsequent Quarterly Dividend Payment Date, a dividend of $0.02 per 
share on the Series A Preferred Stock shall nevertheless be payable on such 
subsequent Quarterly Dividend Payment Date.

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

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

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

          (b)     Except as otherwise provided herein, in any other 
Certificate of Determination creating a series of Preferred Stock or any 
similar stock, or by law, the holders of shares of Series A Preferred Stock 
and the holders of shares of Common Stock and any other capital stock of the 
Company having general voting rights shall vote together as one class on all 
matters submitted to a vote of shareholders of the Company.

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

     Section 4.     Certain Restrictions.

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


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

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

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

          (iv)     redeem or purchase or otherwise acquire for consideration 
any shares of Series A Preferred Stock or shares of any stock ranking on a 
parity with the Series A Preferred Stock, except in accordance with a purchase 
offer made in writing or by publication (as determined by the Board 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 and classes.

          (b)     The Company shall not permit any subsidiary of the Company 
to purchase or otherwise acquire for consideration any shares of stock of the 
Company unless the Company could, under paragraph (a) of this Section 4, 
purchase or otherwise acquire such shares at such time and in such manner.

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

     Section 6.     Liquidation, Dissolution or Winding Up.  Upon any 
liquidation, dissolution or winding up of the Company, no distribution shall 
be made (a) to the holders of shares of stock ranking junior (either as to 
dividends or upon liquidation, dissolution or winding up) to the Series A 
Preferred Stock unless, prior thereto, the holders of shares of Series A 
Preferred Stock shall have received $1.00 per share, plus an amount equal to 
accrued and unpaid dividends and distributions thereon, whether or not 
declared, to the date of such payment, provided, that the holders of shares of 
Series A Preferred Stock shall be entitled to receive an aggregate amount per 
share, subject to the provision for adjustment hereinafter set forth, equal to 
100 times the aggregate amount to be distributed per share to holders of 
shares of Common Stock, or (b) to the holders of shares of stock ranking on a 
parity (either as to dividends or upon liquidation, dissolution or winding up) 
with the Series A Preferred Stock, except distributions made ratably on the 
Series A Preferred Stock and all such parity stock in proportion to the total 
amounts to which the holders of all such shares are entitled upon such 
liquidation, dissolution or winding up.  In the event the Company shall at any 
time declare or pay any dividend on the Common Stock payable in shares of 
Common Stock, or effect a subdivision or combination or consolidation of the 
outstanding shares of Common Stock (by reclassification or otherwise than by 
payment of a dividend in shares of Common Stock) into a greater or lesser 
number of shares of Common Stock, then in each such case the aggregate amount 
to which holders of shares of Series A Preferred Stock were entitled 
immediately prior to such event under the proviso in clause (a) of the 
preceding sentence shall be adjusted by multiplying such amount by a fraction, 
the numerator of which is the number of shares of Common Stock outstanding 
immediately after such event and the denominator of which is the number of 
shares of Common Stock that were outstanding immediately prior to such event.

     Section 7.     Consolidation, Merger, Etc.  In case the Company shall 
enter into any consolidation, merger, combination or other transaction in 
which the shares of Common Stock are exchanged for or changed into other stock 
or securities, cash and/or any other property, then in any such case each 
share of Series A Preferred Stock shall at the same time be similarly 
exchanged or changed into an amount per share, subject to the provision for 
adjustment hereinafter set forth, equal to 100 times the aggregate amount of 
stock, securities, cash and/or any other property (payable in kind), as the 
case may be, into which or for which each share of Common Stock is changed or 
exchanged.  In the event the Company shall at any time declare or pay any 
dividend on the Common Stock payable in shares of Common Stock, or effect a 
subdivision, combination or consolidation of the outstanding shares of Common 
Stock (by reclassification or otherwise than by payment of a dividend in 
shares of Common Stock) into a greater or lesser number of shares of Common 
Stock, then in each such case the amount set forth in the preceding sentence 
with respect to the exchange or change of shares of Series A Preferred Stock 
shall be adjusted by multiplying such amount by a fraction, the numerator of 
which is the number of shares of Common Stock outstanding immediately after 
such event and the denominator of which is the number of shares of Common 
Stock that were outstanding immediately prior to such event.

     Section 8.     No Redemption.  The shares of Series A Preferred Stock 
shall not be redeemable.

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

     Section 10.     Amendment.  The Articles of Incorporation shall not be 
amended in any manner which would materially alter or change the powers, 
preferences or special rights of the Series A Preferred Stock so as to affect 
them adversely without the affirmative vote of the holders of at least 
two-thirds of the outstanding shares of Series A Preferred Stock, voting 
together as a single class.

          IN WITNESS WHEREOF, the Company has caused this Certificate of 
Determination to be duly executed on its behalf by its undersigned Chief 
Executive Officer and attested to by its Secretary this 3rd day of March, 
1998.

       This certifies that _________________________, or registered assigns, is

                         SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES


          On February 23, 1998, the Board of Directors of HemaCare Corporation 
(the "Company") declared a dividend of one preferred share purchase right (a 
"Right") for each outstanding share of common stock, without par value (the 
"Common Shares"), of the Company.  The dividend is payable on March 10, 1998 
to the shareholders of record on March 3, 1998 (the "Record Date").  Each 
Right entitles the registered holder to purchase from the Company one 
one-hundredth of a share of Series A Junior Participating Preferred Stock, 
without par value (the "Preferred Shares"), of the Company, at a price of 
$5.00 per one-hundredth of a Preferred Share (the "Purchase Price"), subject 
to adjustment.  The description and terms of the Rights are set forth in a 
Rights Agreement (the "Rights Agreement") between the Company and U.S. Stock 
Transfer Company, as Rights Agent (the "Rights Agent").

          Until the earlier to occur of:

     (i)     the close of business on the tenth day, after a public 
announcement that a person or a group of affiliated or associated persons 
(other than the Company, any subsidiary of the Company, any employee benefit 
plan of the Company or a subsidiary of the Company or any entity holding 
Common Shares for or pursuant to the terms of any such plan) (an "Acquiring 
Person") has acquired beneficial ownership of 15% or more of the outstanding 
Common Shares;

     (ii)     the close of business on tenth business day (or such later date 
as may be determined by action of the Board of Directors prior to such time as 
any person becomes an Acquiring Person) after the commencement of, or the 
first public announcement of an intention of any person (other than the 
Company, any subsidiary of the Company, any employee benefit plan of the 
Company or a subsidiary of the Company, or any entity holding Common Shares 
for or pursuant to any such plan) to commence, a tender or exchange offer the 
consummation of which would result in the beneficial ownership by such person 
or group of 15% or more of the then outstanding Common Shares;
                                   -1-
<PAGE>

     (iii)     the close of business on the tenth day after all of the 
following events have occurred:  (A) the Board of Directors designates a 
specific limitation (the "Ownership Limitation") on the amount of Common Stock 
which a specified person may beneficially own (which may be more or less than 
such person actually then owns), (B) the Board determines (x) that the 
acquisition by such person of an amount of Common Shares exceeding the 
Ownership Limitation is, or would likely be, intended to cause the Company to 
repurchase the Common Shares beneficially owned by such person or to cause 
pressure on the Company to take action or enter into a transaction or series 
of transaction intended to provide such person with short-term financial gain 
under circumstances where the Board determines that the best long-term 
interests of the Company and its shareholders would not be served by taking 
such action or entering into such transactions at that time, or (y) that 
Beneficial Ownership by such Person of an amount of Common Shares exceeding 
the ownership Limitation is causing or reasonably likely to cause a material 
adverse impact (including, but not limited to, impairment of relationships 
with customers or impairment of the Company's ability to maintain its 
competitive position) on the business or prospects of the Company, and (C) the 
specified person or group obtains or has obtained (either before or after the 
events described in (A) and (B), above) a number of shares of Common Stock 
which exceeds the Ownership Limitation (thereby becoming an "Adverse Person"); 
or

     (iv)     with respect to the dates described in (i) and (ii), above, such 
later date or dates as the Board of Directors may designate; provided, that if 
a later date or dates are designated, such designation shall be made on or 
before the earlier of the dates specified in (i) or (ii) above;

(the earlier of such dates being called the "Distribution Date"), the Rights 
will be evidenced, with respect to any of the Common Share certificates 
outstanding as of the Record Date, by such Common Share certificate with a 
copy of this Summary of Rights attached to the Rights Agreement as Exhibit C 
(the "Summary of Rights") attached thereto.

          The Rights Agreement provides that, until the Distribution Date or 
earlier redemption or expiration of the Rights, (i) the Rights will be 
transferred with and only with the Common Shares, (ii) new Common Share 
certificates issued after the Record Date upon transfer or new issuance of 
Common Shares will contain a notation incorporating the Rights Agreement by 
reference, and (iii) the surrender for transfer of any certificates for Common 
Shares outstanding as of the Record Date, with or without such notation or a 
copy of the Summary of Rights being attached thereto, will also
                                  -2-
<PAGE>
constitute the transfer of the Rights associated with the Common Shares
represented by such certificate.  As soon as practicable after the Distribution
Date, separate certificates evidencing the Rights ("Right Certificates") will
be mailed to holders of record of the Common Shares as of the close of
business on the Distribution Date, and such separate Right Certificates
alone will evidence the Rights as of and after the Distribution Date.

          The Rights are not exercisable until the Distribution Date.  The 
Rights will expire on March 10, 2008 (the "Final Expiration Date"), unless the 
Final Expiration Date is extended or unless the Rights are earlier redeemed by 
the Company, in each case as described below.

          The Purchase Price payable, and the number of Preferred Shares or 
other securities or property issuable, upon exercise of the Rights are subject 
to adjustment from time to time to prevent dilution in the event that the 
Company (i) declares a dividend on the Preferred Shares that is payable in 
Preferred Shares, (ii) subdivides, combines or reclassifies the outstanding 
Preferred Shares, (iii) grants to holders of the Preferred Shares certain 
rights or warrants to subscribe for or purchase Preferred Shares at a price, 
or securities convertible into Preferred Shares with a conversion price, less 
than the then current market price of the Preferred Shares, or (iv) 
distributes to holders of the Preferred Shares evidences of indebtedness or 
assets (excluding regular periodic cash dividends paid out of earnings or 
retained earnings or dividends payable in Preferred Shares) or subscription 
rights or warrants (other than those referred to above).

          In the event that (i) any person becomes an Acquiring Person (unless 
such person first acquires 15% or more of the outstanding Common Shares 
through a tender offer which meets all of the following criteria: the tender 
offer (A) is made in the manner prescribed by Section 14(d) of the Securities 
Exchange Act of 1934, as amended, and the rules of the Securities and Exchange 
Commission, (B) is delivered to the Company in a written proposal, (C) is made 
by a person who both owns 1% or less of the Company's outstanding Common Stock 
and has not, during the last year, indicated an interest in acquiring control 
of the Company at any time when it owned more than 1% of the outstanding 
Common Stock, (D) is for the acquisition of all the Company's outstanding 
Common Stock and other voting securities for cash, (E) is accompanied by a 
written opinion of a nationally recognized investment banking firm stating 
that the price to be paid for each class of outstanding Common Stock or other 
voting securities is fair to the holders thereof, (F) states that the offeror 
has obtained written financing commitments from recognized financing sources, 
and/or has on hand cash or cash equivalents, sufficient to consummate the 
tender offer, and (G) causes the offeror to be the owner of 80% or more of the 
Company's outstanding Common Stock and other voting securities); or (ii) a
                                    -3-
<PAGE>

person becomes an Adverse Person, proper provision shall be made so that each 
holder of a Right (other than Rights beneficially owned by the Acquiring 
Person or Adverse Person and their respective associates and affiliates, which 
will thereafter be void), will thereafter have the right to receive, upon 
exercise thereof, at a price equal to the then current Purchase Price 
multiplied by the number of one-hundredths of a Preferred Share for which a 
Right is then exercisable, and in lieu of Preferred Shares, that number of 
Common Shares having a market value of two times the exercise price of such 
Right.

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

          At any time after a person becomes an Acquiring Person, but before 
any Acquiring Person or Adverse Person acquires 50% or more of the outstanding 
Common Shares, the Board of Directors of the Company may exchange the Rights 
(other than Rights owned by such Acquiring Person or group which have become 
void), in whole or in part, for Common Stock or Preferred Stock of the Company 
at an exchange ratio of one Common Share (or 1/100 of a Preferred Share) per 
Right, subject to adjustment as provided in the Rights Plan.

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

          At any time before the earlier of (i) the tenth day following the 
date on which any Acquiring Person (or the Company) announces that such 
Acquiring Person has obtained 15% or more of the Company's outstanding Common 
Stock, (ii) the tenth day following the date on which any person becomes an 
Adverse Person, (iii) such later date as the Board of Directors, or any 
authorized committee of the Board, may designate (if it does so before the 
time periods specified above have expired), or (iv) the Final Expiration Date, 
the Board of Directors of the Company may redeem all, but not less than all, 
                                    -4-
<PAGE>

of the then outstanding Rights at a price (subject to adjustment) of $.001 per
Right, rounded upward for each holder to the nearest whole cent (the 
"Redemption Price"), payable in cash or in Common Shares at the discretion of 
the Board of Directors.  The redemption of the Rights may be made effective at 
such time, on such basis and with such conditions as the Board of Directors in 
its sole discretion may establish.  Immediately upon any redemption of the 
Rights, the right to exercise the Rights will automatically terminate and the 
only right of the holders of Rights will be to receive the Redemption Price.

          The terms of the Rights may be amended by the Board of Directors of 
the Company without the consent of the holders of the Rights.  As part of its 
power to amend the Rights Plan, the Board may, at any time before a person 
becomes an Acquiring Person or an Adverse Person, lower the threshold for 
exercisability of the Rights from 15% to not less than the greater of  (i) 11% 
or (ii) any percentage greater than the largest percentage of the outstanding 
Common Shares then known to the Company to be beneficially owned by any person 
or group of affiliated or associated persons (other than the Company or any of 
its subsidiaries, any employee benefit plan of the Company or any of its 
subsidiaries, or any entity holding Common Shares for or pursuant to any such 
plan).  From and after such time as any person becomes an Acquiring Person or 
an Adverse Person, however, no amendment may be made which would adversely 
affect the interests of the holders of the Rights (other than an Acquiring or 
Adverse Person or their affiliates or associates).

          Until a Right is exercised, the holder thereof, as such, will have 
no rights as a shareholder of the Company, including, without limitation, the 
right to vote or to receive dividends.  While the distribution of the Rights 
will not be taxable to the Company's shareholders or to the Company itself, 
the shareholders may, depending on circumstances, recognize taxable income in 
the event that the Rights become exercisable for Common Stock of the Company 
or for common stock of the acquiring company, as set forth above.

          A copy of the Rights Agreement has been filed with the Securities 
and Exchange Commission as an Exhibit to a Registration Statement on Form 8-K 
dated March 5, 1998.  A copy of the Rights Agreement is available free of 
charge from the Company.  This summary description of the Rights does not 
purport to be complete and is qualified in its entirety by reference to the 
Rights Agreement, which is incorporated herein by reference.
