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

         On May 16, 1997, the Board of Directors of EIS International, Inc. (the
"Company" or the "Registrant"), declared a dividend of one preferred stock
purchase right (a "Right") for each outstanding share of the Company's common
stock, $.01 par value per share (the "Common Stock"), to stockholders of record
at the close of business on May 27, 1997 (the "Record Date"). Each Right
entitles the registered holder to purchase from the Company a unit consisting of
one one-thousandth of a share (a "Unit") of Series A Junior Participating
Preferred Stock, $.01 par value (the "Preferred Stock"), at a purchase price of
$20.00 in cash per Unit (the "Purchase Price"), subject to adjustment. The
description and terms of the Rights are set forth in a Rights Agreement dated as
of May 16, 1997 (the "Rights Agreement") between the Company and BankBoston, 
N.A., as Rights Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 20% or more of the outstanding shares of Common Stock (the "Stock
Acquisition Date"), or (ii) 10 business days following the commencement of a
tender offer or exchange offer that would result in a person or group
beneficially owning 20% or more of such outstanding shares of Common Stock.
Until the Distribution Date (or earlier redemption or expiration of the rights),
(i) the Rights will be evidenced by the Common Stock certificates and will be
transferred with and only with such Common Stock certificates, (ii) new Common
Stock certificates issued after the Record Date will contain a notation
incorporating the Rights Agreement by reference and (iii) the surrender for
transfer of any certificates for Common Stock outstanding, even without such
notation, will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate.

         The Rights are not exercisable until the Distribution Date and will
expire upon the earlier of the close of business on May 16, 2007 (the "Final
Expiration Date") or the redemption or exchange of the Rights as described
below.

         As soon as practicable after the Distribution Date, separate
certificates evidencing the Rights ("Rights Certificates") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date and, thereafter, such separate Rights Certificates alone will
represent the Rights. Except as otherwise determined by the Board of Directors
and except in connection with shares of Common Stock issued upon the exercise of
employee stock options, issuances under other employee stock benefit plans or
the conversion of convertible securities issued


                                       -2-

<PAGE>


hereafter, only shares of Common Stock issued prior to the Distribution Date
will be issued with Rights.

         In the event that any stockholder becomes an Acquiring Person, unless
the event causing the 20% threshold to be crossed is a Permitted Offer (as
defined in the Rights Agreement) or is otherwise exempted under the terms of the
Rights Agreement, then, promptly following the first occurrence of such event,
proper provision shall be made so that each holder of a Right (except as
provided below and in Section 7(e) of the Rights Agreement) shall thereafter
have the right to receive, upon exercise thereof at the then current Purchase
Price, in lieu of a number of one one-thousandths of a share of Preferred Stock,
such number of shares of Common Stock of the Company that equals the result
obtained by (x) multiplying the then current Purchase Price by the then number
of one one-thousandths of a share of Preferred Stock for which a Right is then
exercisable, and (y) dividing that product) by 50% of the current market price
per share of Common Stock on the date of such first occurrence. Notwithstanding
any of the foregoing, following the occurrence of the event set forth in this
paragraph, all Rights that are, or (under certain circumstances specified in the
Rights Agreement) were, beneficially owned by any Acquiring Person will be null
and void. The event set forth in this paragraph is referred to as "Section
11(a)(ii) Event."

         In the event that, at any time after any Person becomes an Acquiring
Person, (i) the Company is acquired in a merger or other business combination
transaction in which the Company is not the surviving corporation or its Common
Stock is changed or exchanged (other than a merger which follows a Permitted
Offer and satisfies certain other conditions), or (ii) 50% or more of the
Company's assets or earning power is sold or transferred, each holder of a Right
(except Rights which previously have been voided as set forth above) shall
thereafter have the right to receive, upon exercise, that number of shares of
common stock of the acquiring company which equals the exercise price of the
Right divided by one-half of the current market price of such common stock at
the date of the occurrence of the event. The events set forth in this paragraph
are referred to as "Section 13 Events." Section 11(a)(ii) Events and Section 13
Events are collectively referred to as "Triggering Events."

         At any time after the occurrence of a Section 11(a)(ii) Event, subject
to certain conditions, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring Person which have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or one one-thousandth of a share of Preferred Stock (or of a share of a class or
series of the Company's preferred stock having equivalent rights, preferences
and privileges), per Right (subject to adjustment).

         The Purchase Price payable, and the number of Units of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to


                                       -3-

<PAGE>


adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock, (ii) if holders of the Preferred Stock are granted certain rights or
warrants to subscribe for Preferred Stock or convertible securities at less than
the then-current market price of the Preferred Stock, or (iii) upon the
distribution to holders of the Preferred Stock of evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings) or of subscription rights or warrants (other than those
referred to above).

         The number of Rights associated with each share of Common Stock is also
subject to adjustment in the event of a stock split of the Common Stock or a
stock dividend on the Common Stock payable in Common Stock or subdivisions,
consolidations or combinations of the Common Stock occurring, in any such case,
prior to the Distribution Date.

         Preferred Stock purchasable upon exercise of the Rights will not be
redeemable. Each share of Preferred Stock will be entitled to a minimum
preferential quarterly dividend payment of $1.00 per share and will be entitled
to an aggregate dividend of 1,000 times the dividend declared per share of
Common Stock. In the event of liquidation, the holders of the Preferred Stock
will be entitled to a minimum preferential liquidation payment of $1,000 per
share and will be entitled to an aggregate payment of 1,000 times the payment
made per share of Common Stock. Each share of Preferred Stock will have 1,000
votes, voting together with the Common Stock. Finally, in the event of any
merger, consolidation or other transaction in which Common Stock is exchanged,
each share of Preferred Stock will be entitled to receive 1,000 times the amount
received per share of Common Stock. These rights are protected by customary
antidilution provisions.

         Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of one one-thousandth of a share of Preferred Stock
purchasable upon exercise of each Right should approximate the value of one
share of Common Stock.

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. No fractional Units will be issued and, in lieu thereof, an adjustment in
cash will be made based on the market price of the Preferred Stock on the last
trading date prior to the date of exercise.

         At any time prior to the earlier of (i) the close of business on the
tenth day following the Stock Acquisition Date or (ii) the Final Expiration
Date, the Company may redeem the Rights in whole, but not in part, at a price of
$.01 per Right (the "Redemption Price"), payable in cash or stock. Immediately
upon the action of the


                                       -4-

<PAGE>


Board of Directors ordering redemption of the Rights, the Rights will terminate
and the only right of the holders of Rights will be to receive the Redemption
Price.

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

         Subject to certain exceptions, any of the provisions of the Rights
Agreement may be amended by the Board of Directors of the Company prior to the
Distribution Date.

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to this Registration Statement on Form 8-A. 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.

                                RIGHTS AGREEMENT

         RIGHTS AGREEMENT, dated as of May 16, 1997 (the "Agreement"), between
EIS International, Inc., a Delaware corporation (the "Company"), and BankBoston,
N.A., a national banking association, as Rights Agent (the "Rights Agent").

                               W I T N E S S E T H
                               -------------------


         WHEREAS, on May 16, 1997 the Board of Directors of the Company (the
"Board") authorized and declared a dividend distribution of one Right for each
share of Common Stock (as hereinafter defined) of the Company outstanding at the
close of business on May 27, 1997 (the "Record Date"), and authorized the
issuance of one Right (as such number may hereinafter be adjusted pursuant to
the provisions of Section 11(p) hereof) for each share of Common Stock of the
Company issued between the Record Date (whether originally issued or delivered
from the Company's treasury) and the earlier of the Distribution Date or the
Expiration Date, each Right initially representing the right to purchase one
one-thousandth of a share of Series A Junior Participating Preferred Stock of
the Company having the rights, powers and preferences set forth in the form of
Certificate of Designations attached hereto as Exhibit A, upon the terms and
subject to the conditions hereinafter set forth (the "Rights");

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

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

                  (a) "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 20% or more of the shares of Common Stock then outstanding,
but shall not include (i) the Company, (ii) any Subsidiary of the Company, (iii)
any employee benefit plan of the Company or of any Subsidiary of the Company or
(iv) any Person organized, appointed or established by the Company for or
pursuant to the terms of any such plan. Notwithstanding the foregoing, no Person
shall become an "Acquiring Person" as the result of an acquisition of Common
Stock by the Company which, by reducing the number of shares outstanding,
increases the proportionate number of shares beneficially owned by such Person
to 20% or more of the shares of Common Stock of the Company then outstanding;
provided, however, that if a Person shall become the Beneficial Owner of 20% or
more of the shares of Common Stock of the Company then outstanding by reason of
share purchases by the Company and shall, after such share purchases by the
Company, become the


<PAGE>


Beneficial Owner of any additional Common Stock of the Company, then such Person
shall be deemed to be an "Acquiring Person." Notwithstanding the foregoing, if
the Board of Directors of the Company determines in good faith that a Person who
would otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently, and such Person
divests as promptly as practicable a sufficient number of shares of Common Stock
so that such Person would no longer be an "Acquiring Person," as defined
pursuant to the foregoing provisions of this paragraph (a), then such Person
shall not be deemed to be an "Acquiring Person" for any purposes of this
Agreement unless and until such Person shall again become an "Acquiring Person."

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

                  (c) "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended and in effect
on the date of this Agreement (the "Exchange Act").

                  (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, directly or indirectly, has the right to acquire (whether
         such right is exercisable immediately or only after the passage of
         time) pursuant to any agreement, arrangement or understanding (other
         than customary agreements with and between underwriters and selling
         group members with respect to a bona fide public offering of
         securities), whether or not in writing, or upon the exercise of
         conversion rights, exchange rights, other rights, warrants or options,
         or otherwise; provided, however, that a Person shall not be deemed the
         "Beneficial Owner" of, or to "beneficially own," (A) securities
         tendered pursuant to a tender or exchange offer made by such Person or
         any of such Person's Affiliates or Associates until such tendered
         securities are accepted for purchase or exchange, or (B) securities
         issuable upon exercise of Rights at any time prior to the occurrence of
         a Triggering Event, or (C) securities issuable upon exercise of Rights
         from and after the occurrence of a Triggering Event which Rights were
         acquired by such Person or any of such Person's Affiliates or
         Associates prior to the Distribution Date or pursuant to Section 3(a)
         or Section 22 hereof (the "Original Rights") or pursuant to Section
         11(i) hereof in connection with an adjustment made with respect to any
         Original Rights;

                  (ii) which such Person or any of such Person's Affiliates or
         Associates, directly or indirectly, has the right to vote or dispose of
         or has "beneficial ownership" of (as determined pursuant to Rule 13d-3
         of the General Rules and Regulations under the Exchange Act, or any
         comparable or


                                       -2-

<PAGE>



         successor rule), including pursuant to any agreement, arrangement or
         understanding (other than customary agreements with and between
         underwriters and selling group members with respect to a bona fide
         public offering of securities), whether or not in writing; provided,
         however, that a Person shall not be deemed the "Beneficial Owner" of,
         or to "beneficially own," any security under this subparagraph (ii) as
         a result of an agreement, arrangement or understanding to vote such
         security if such agreement, arrangement or understanding: (A) arises
         solely from a revocable proxy given in response to a public proxy or
         consent solicitation made pursuant to, and in accordance with, the
         applicable provisions of the General Rules and Regulations under the
         Exchange Act, and (B) is not then reportable by such Person on Schedule
         13D under the Exchange Act (or any comparable or successor report); or

                  (iii) 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
         pursuant to a revocable proxy as described in the proviso to
         subparagraph (ii) of this paragraph (d)) or disposing of any voting
         securities of the Company.

         For all purposes of this Agreement, any calculation of the number of
shares of Common Stock outstanding at any particular time, including for
purposes of determining the particular percentage of such outstanding shares of
Common Stock of which any Person is the Beneficial Owner, shall be made in
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules
and Regulations under the Exchange Act.

                  (e) "Business Day" shall mean any day other than a Saturday,
Sunday or a day on which banking institutions in the State of New York are
authorized or obligated by law or executive order to close.

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

                  (g) "Common Stock" shall mean the common stock, $.01 par
value, of the Company, except that "Common Stock" when used with reference to
any Person other than the Company shall mean the capital stock of such Person
with the greatest voting power, or the equity securities or other equity
interest having power to control or direct the management, of such Person.

                  (h) "Common stock equivalents" shall have the meaning set
forth in Section 11(a)(iii) hereof.

                  (i) "Continuing Director" shall mean (i) any member of the
Board, while such Person is a member of the Board, who is not an Acquiring
Person, or an Affiliate or Associate of an Acquiring Person, or a representative
of an Acquiring Person or of any such Affiliate or Associate, and was a member
of the Board prior to the date of this Agreement, or (ii) any Person who
subsequently becomes a member of the Board, while such Person is a member of the
Board, who is not an Acquiring Person, or an Affiliate or Associate of an
Acquiring Person, or a representative of an Acquiring Person or of any such
Affiliate or Associate, if such Person's nomination for election or election to
the Board is recommended or approved by a majority of the Continuing Directors.

                  (j) "Current market price" shall have the meaning set forth in
Section 11(d)(i) hereof.

                  (k) "Current Value" shall have the meaning set forth in
Section 11(a)(iii) hereof.

offer for all outstanding shares of Common Stock at a price and on terms
determined by at least a majority of the members of the Board of Directors who
are not officers of the Company and who are not representatives, nominees,
Affiliates or Associates of an Acquiring Person, after receiving advice from a
nationally recognized investment banking firm selected by the Board of Directors
of the Company, to be (a) at a price that is fair to stockholders (taking into
account all factors which such members of the Board deem relevant including,
without limitation, prices which could reasonably be achieved if the Company or
its assets were sold on an orderly basis designed to realize maximum value) and
(b) otherwise in the best interests of the Company and its stockholders.

<PAGE>


Rule 14d-2(a) of the General Rules and Regulations under the Exchange Act, if
upon consummation thereof, such Person would be the Beneficial Owner of 20% or
more of the shares of Common Stock then outstanding (the earlier of (i) and (ii)
being herein referred to as the "Distribution Date"), (x) the Rights will be
evidenced (subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock registered in the names of the holders of the
Common Stock (which certificates for Common Stock shall be deemed also to be
certificates for Rights) and not by separate certificates, and (y) the Rights
will be transferable only in connection with the transfer of the underlying
shares of Common Stock (including a transfer to the Company). As soon as
practicable after the Distribution Date, the Rights Agent will send by
first-class, insured, postage prepaid mail, to each record holder of the Common
Stock as of the close of business on the Distribution Date, at the address of
such holder shown on the records of the Company, one or more rights
certificates, in substantially the form of Exhibit B hereto (the "Rights
Certificates"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in the
number of Rights per share of Common Stock has been made pursuant to Section
11(p) hereof, at the time of distribution of the Right Certificates, the Company
shall make the necessary and appropriate rounding adjustments (in accordance
with Section 14(a) hereof) so that Rights Certificates representing only whole
numbers of Rights are distributed and cash is paid in lieu of any fractional
Rights. As of and after the Distribution Date, the Rights will be evidenced
solely by such Rights Certificates.

                  (b) As promptly as practicable following the Record Date, the
Company will send a copy of a Summary of Rights to Purchase Preferred Stock, in
substantially the form attached hereto as Exhibit C, by first-class, postage
prepaid mail, to each record holder of the Common Stock as of the close of
business on the Record Date, at the address of such holder shown on the records
of the Company. With respect to certificates for the Common Stock outstanding as
of the close of business on the Record Date, until the Distribution Date, the
Rights will be evidenced by such certificates for the Common Stock and the
registered holders of the Common Stock shall also be the registered holders of
the associated Rights.

                  (c) Rights shall be issued in respect of all shares of Common
Stock that are issued (either as an original issuance or from the Company's
treasury) after the Record Date but prior to the earlier of the Distribution
Date or the Expiration Date. Certificates representing such shares of Common
Stock (including, without limitation, certificates issued upon transfer or
exchange of Common Stock) shall also be deemed to be certificates for Rights,
and shall bear the following legend:

         This certificate also evidences and entitles the holder hereof to
certain Rights as set forth in the Rights Agreement between EIS International,
Inc. (the "Company") and BankBoston, N.A. (the "Rights Agent") dated as of 
May 16, 1997, as the same may be amended, restated or renewed from time to time
(the "Rights


                                       -7-

<PAGE>


Agreement"), the terms of which are hereby incorporated herein by reference and
a copy of which is on file at the principal offices of the Company. Under
certain circumstances, as set forth in the Rights Agreement, such Rights will be
evidenced by separate certificates and will no longer be evidenced by this
certificate. The Company will mail to the holder of this certificate a copy of
the Rights Agreement, as in effect on the date of mailing, without charge
promptly after receipt of a written request therefor. Under certain
circumstances set forth in the Rights Agreement, Rights issued to, or held by,
any Person who is, was or becomes an Acquiring Person or any Affiliate or
Associates thereof (as such terms are defined in the Rights Agreement), whether
currently held by or on behalf of such Person or by any subsequent holder, may
become null and void.

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

                  (d) Until the earlier of the Distribution Date or the
Expiration Date (as such term is defined in Section 7 hereof), the transfer of
any certificates representing shares of Common Stock in respect of which Rights
have been issued shall also constitute the transfer of the Rights associated
with such shares of Common Stock. In the event that the Company purchases or
acquires any shares of Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such shares of Common Stock shall
be deemed cancelled and retired so that the Company shall not be entitled to
exercise any Rights associated with the shares of Common Stock which are no
longer outstanding.

                  (e) In connection with the issuance or sale of shares of
Common Stock following the Distribution Date and prior to the Expiration Date,
the Company (i) shall, with respect to shares of Common Stock so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement, or upon the exercise, conversion or exchange of securities issued
by the Company, and (ii) may, in any other case, if deemed necessary or
appropriate by the Board of Directors of the Company, issue Rights Certificates
representing the appropriate number of Rights in connection with such issuance
or sale; provided, however, that (A) no such Rights Certificate shall be issued
if, and to the extent that, the Company shall be advised by counsel that such
issuance would create a significant risk of material adverse tax consequences to
the Company or the Person to whom such Rights Certificate would be issued, and
(B) no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

         Section 4.  Form of Rights Certificates.

<PAGE>


                  (a) The Rights Certificates (and the forms of election to
purchase, certification and assignment to be printed on the reverse thereof)
shall each be substantially in the form set forth in Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or over-the-counter
market on which the Rights may from time to time be listed, or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever distributed, shall entitle the holders thereof to
purchase such number of one one-thousandths of a share of Preferred Stock as
shall be set forth therein at the price set forth therein (such exercise price
per one one-thousandth of a share, the "Purchase Price"), but the amount and
type of securities purchasable upon the exercise of each Right and the Purchase
Price thereof shall be subject to adjustment as provided herein.

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

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


                                       -9-

<PAGE>


         The absence of the foregoing legend on any Rights Certificate shall in
no way affect any of the other provisions of this Agreement, including, without
limitation, the provisions of Section 7(e) hereof.

         Section 5.  Countersignature and Registration.

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

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

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

                  (a) Subject to the provisions of Section 4(b), Section 7(e)
and 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 Expiration
Date, any Rights Certificate or Certificates (other than Rights Certificates
representing Rights that have become void pursuant to Section 7(e) hereof or
that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Rights Certificate or Certificates,
entitling the registered holder to purchase a like number of one one-thousandths
of a share of Preferred Stock (or, following a Triggering Event, Common Stock,
other securities, cash or other assets, as the case may be) as the Rights
Certificate or Certificates surrendered then entitled such holder (or former


                                      -10-

<PAGE>



holder in the case of a transfer) to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Rights Certificate or Certificates
shall make such request in writing delivered to the Rights Agent, and shall
surrender the Rights Certificate or Certificates to be transferred, split up,
combined or exchanged, with the form of assignment and certificate appropriately
executed, at the office of the Rights Agent designated for such purpose. Neither
the Rights Agent nor the Company shall be obligated to take any action
whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Section 4(b), Section 7(e) and Section 14 hereof,
countersign and deliver to the Person entitled thereto a Rights Certificate or
Rights Certificates, as the case may be, as so requested. The Company may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer, split up, combination or
exchange of Rights Certificates.

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

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

                  (a) Subject to Section 7(e) hereof, the registered holder of
any Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly executed, to the Rights Agent
at the office of the Rights Agent designated for such purpose, together with
payment of the aggregate Purchase Price with respect to the total number of one
one-thousandths of a share of Preferred Stock (or other securities, cash or
other assets, as the case may be) as to which such surrendered Rights are then
exercisable, at or prior to the earliest of (i) the Final Expiration Date, (ii)
the time at which the Rights expire as provided in Section 13(d) hereof, (iii)
the time at which the Rights are redeemed as provided in Section 23 hereof (the
"Redemption Date") or


                                      -11-

<PAGE>


(iv) the time at which such Rights are exchanged as provided in Section 24
hereof (the earliest of (i), (ii), (iii) and (iv) being herein referred to as
the "Expiration Date").

                  (b) The Purchase Price for each one one-thousandth of a share
of Preferred Stock pursuant to the exercise of a Right shall initially be
$20.00, and shall be subject to adjustment from time to time as provided in
Sections 11 and 13(a) hereof and shall be payable in accordance with paragraph
(c) below.

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

                  (d) In case the registered holder of any Rights Certificate
shall exercise less than all the Rights evidenced thereby, a new Rights
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent and delivered to, or upon the order of, the
registered holder of such


                                      -12-

<PAGE>


Rights Certificate, registered in such name or names as may be designated by
such holder, subject to the provisions of Section 14 hereof.

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Section 11(a)(ii) Event, any
Rights beneficially owned by (i) an Acquiring Person or an Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee after the Acquiring
Person becomes such, or (iii) a transferee of an Acquiring Person (or of any
such Associate or Affiliate) who becomes a transferee prior to or concurrently
with the Acquiring Person becoming such and receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from the Acquiring
Person to holders of equity interests in such Acquiring Person or to any Person
with whom the Acquiring Person has any continuing agreement, arrangement or
understanding regarding the transferred Rights or (B) a transfer which the Board
of Directors of the Company has determined is part of a plan, arrangement or
understanding that has as a primary purpose or effect the avoidance of this
Section 7(e), shall become null and void without any further action and no
holder of such Rights shall have any rights whatsoever with respect to such
Rights, whether under any provision of this Agreement or otherwise. The Company
shall use all reasonable efforts to insure that the provisions of this Section
7(e) and Section 4(b) hereof are complied with, but shall have no liability to
any holder of Rights Certificates or other Person as a result of its failure to
make any determinations with respect to an Acquiring Person or its Affiliates,
Associates or transferees hereunder.

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

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


                                      -13-

<PAGE>


written request of the Company, destroy such cancelled Rights Certificates, and
in such case shall deliver a certificate of destruction thereof to the Company.

         Section 9.  Reservation and Availability of Capital Stock.

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

                  (b) So long as the shares of Preferred Stock (and, following
the occurrence of a Triggering Event, Common Stock and/or other securities)
issuable and deliverable upon the exercise of the Rights are eligible for
listing on any national securities exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable, all
shares reserved for such issuance to be listed on such exchange upon official
notice of issuance upon such exercise.

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


                                      -14-

unless the requisite registration or qualification in such jurisdiction shall
have been effected or obtained.

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

                  (e) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
that may be payable in respect of the issuance or delivery of the Rights
Certificates and of any certificates for a number of one one-thousandths of a
share of Preferred Stock (or Common Stock and/or other securities, as the case
may be) upon the exercise of Rights. The Company shall not, however, be required
(i) to pay any transfer tax that may be payable in respect of any transfer or
delivery of Rights Certificates to a Person other than, or the issuance or
delivery of a number of one one-thousandths of a share of Preferred Stock (or
Common Stock and/or other securities, as the case may be) in respect of a name
other than that of, the registered holder of the Rights Certificate evidencing
Rights surrendered for exercise or (ii) to issue or deliver any certificates for
a number of one one-thousandths of a share of Preferred Stock (or Common Stock
and/or other securities, as the case may be) in a name other than that of the
registered holder upon the exercise of any Rights until such tax shall have been
paid (any such tax being payable by the holder of such Rights Certificate at the
time of surrender) or until it has been established to the Company's
satisfaction that no such tax is due.

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


                                      -15-

<PAGE>


any rights of a stockholder of the Company with respect to securities for which
the Rights shall be exercisable, including, without limitation, the right to
vote, to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of
the Company, except as provided herein.

         Section 11. Adjustment of Purchase Price, Number and Kind of Shares or
Number of Rights. The Purchase Price, the number and kind of shares covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

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

                  (ii) Subject to Section 24 of this Agreement, in the event
         that any Person, alone or together with its Affiliates or Associates,
         becomes an Acquiring Person (other than pursuant to a Permitted Offer),
         then, promptly following the first occurrence of such event, proper
         provision shall be made so that each holder of a Right (except as
         provided below and in Section 7(e) hereof) shall thereafter have the
         right to receive, upon exercise thereof at the then current Purchase
         Price in accordance with the terms of this Agreement, in lieu of a
         number of one one-thousandths of a share of Preferred Stock, such
         number of shares of Common Stock of the Company that equals the result


                                      -16-

<PAGE>


         obtained by (x) multiplying the then current Purchase Price by the then
         number of one one-thousandths of a share of Preferred Stock for which a
         Right was exercisable immediately prior to the first occurrence of a
         Section 11(a)(ii) Event, and (y) dividing that product (which,
         following such first occurrence, shall thereafter be referred to as the
         "Purchase Price" for each Right and for all purposes of this Agreement)
         by 50% of the current market price (determined pursuant to Section
         11(d) hereof) per share of Common Stock on the date of such first
         occurrence (such number of shares, the "Adjustment Shares").

                  (iii) In the event that the number of shares of Common Stock
         that are authorized by the Company's Certificate of Incorporation but
         not outstanding or reserved for issuance for purposes other than upon
         exercise of the Rights are not sufficient to permit the exercise in
         full of the Rights in accordance with the foregoing subparagraph (ii)
         of this Section 11(a), the Company shall: (A) determine the excess of
         (1) the value of the Adjustment Shares issuable upon the exercise of a
         Right (the "Current Value") over (2) the Purchase Price (such excess,
         the "Spread"), and (B) with respect to each Right, make adequate
         provision to substitute for the Adjustment Shares, upon payment of the
         applicable Purchase Price, (1) cash, (2) a reduction in the Purchase
         Price, (3) Common Stock or other equity securities of the Company
         (including, without limitation, shares, or units of shares, of
         preferred stock which the Board of Directors of the Company has deemed
         to have the same value as shares of Common Stock (such shares of
         preferred stock, "common stock equivalents")), (4) debt securities of
         the Company, (5) other assets, or (6) any combination of the foregoing,
         having an aggregate value equal to the Current Value, where such
         aggregate value has been determined by the Board of Directors of the
         Company based upon the advice of a nationally recognized investment
         banking firm selected by the Board of Directors of the Company;
         provided, however, if the Company shall not have made adequate
         provision to deliver value pursuant to clause (B) above within thirty
         (30) days following the later of (x) the first occurrence of a Section
         11(a)(ii) Event and (y) the date on which the Company's right of
         redemption pursuant to Section 23(a) expires (the later of (x) and (y)
         being referred to herein as the "Section 11(a)(ii) Trigger Date"), then
         the Company shall be obligated to deliver, upon the surrender for
         exercise of a Right and without requiring payment of the Purchase
         Price, shares of Common Stock (to the extent available) and then, if
         necessary, cash, which shares and/or cash have an aggregate value equal
         to the Spread. If the Board of Directors of the Company shall determine
         in good faith that it is likely that sufficient additional shares of
         Common Stock could be authorized for issuance upon exercise in full of
         the Rights, the thirty (30) day period set forth above may be extended
         to the extent necessary, but not more than ninety (90) days after the
         Section 11(a)(ii) Trigger Date, in order that the Company may seek
         shareholder approval for the authorization of such additional shares
         (such period, as it may be extended, the "Substitution Period"). To the
         extent


                                      -17-

<PAGE>


         that the Company determines that some action need be taken pursuant to
         the first and/or second sentences of this Section 11(a)(iii), the
         Company (x) shall provide, subject to Section 7(e) hereof, that such
         action shall apply uniformly to all outstanding Rights, and (y) may
         suspend the exercisability of the Rights until the expiration of the
         Substitution Period in order to seek any authorization of additional
         shares and/or to decide the appropriate form of distribution to be made
         pursuant to such first sentence and to determine the value thereof. In
         the event of any such suspension, the Company shall issue a public
         announcement stating that the exercisability of the Rights has been
         temporarily suspended, as well as a public announcement at such time as
         the suspension is no longer in effect. For purposes of this Section
         11(a)(iii), the value of the Common Stock shall be the current market
         price (as determined pursuant to Section 11(d) hereof) per share of the
         Common Stock on the Section 11(a)(ii) Trigger Date and the value of any
         "common stock equivalent" shall be deemed to have the same value as the
         Common Stock on such date.

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


                                      -18-

<PAGE>


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 a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash (other than a regular
quarterly cash dividend out of the earnings or retained earnings of the
Company), assets (other than a dividend payable in Preferred Stock, but
including any dividend payable in stock other than Preferred Stock) or
subscription rights or warrants (excluding those referred to in Section 11(b)
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 current market
price (as determined pursuant to Section 11(d) hereof) per share of Preferred
Stock 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 and shall be conclusive for
all purposes) of the portion of the cash, assets or evidences of indebtedness so
to be distributed or of such subscription rights or warrants applicable to a
share of Preferred Stock and the denominator of which shall be such current
market price (as determined pursuant to Section 11(d) hereof) per share of
Preferred Stock on such record date. Such adjustments shall be made successively
whenever such a record date is fixed, and in the event that such distribution is
not so made, the Purchase Price shall be adjusted to be the Purchase Price which
would have been in effect if such record date had not been fixed.

                  (d)(i) For the purpose of any computation hereunder, other
         than computations made pursuant to Section 11(a)(iii) hereof, the
         "current market price" per share of Common Stock on any date shall be
         deemed to be the average of the daily closing prices per share of such
         Common Stock for the thirty (30) consecutive Trading Days (as such term
         is hereinafter defined) immediately prior to such date, and for
         purposes of computations made pursuant to Section 11(a)(iii) hereof,
         the "current market price" per share of Common Stock on any date shall
         be deemed to be the average of the daily closing prices per share of
         such Common Stock for the ten (10) consecutive Trading Days immediately
         following such date; provided, however, that in the event that the
         current market price per share of the Common Stock is determined during
         a period following the announcement by the issuer of such Common Stock
         of (A) a dividend or distribution on such Common Stock payable in
         shares of such Common Stock or securities convertible into shares of
         such Common Stock (other than the Rights), or (B) any subdivision,
         combination or reclassification of such Common Stock, and the
         ex-dividend date for such dividend or distribution, or the record date
         for such subdivision,


                                      -19-

<PAGE>


         combination or reclassification shall not have occurred prior to the
         expiration of the requisite thirty (30) Trading Day or ten (10) Trading
         Day period, as set forth above, then, and in each such case, the
         "current market price" shall be properly adjusted to take into account
         ex-dividend trading. The closing price for each day shall be the last
         sale price, regular way, or, in case no such sale takes place on such
         day, the average of the closing bid and asked prices, regular way, in
         either case as reported in the principal consolidated transaction
         reporting system with respect to securities listed or admitted to
         trading on the New York Stock Exchange or, if the shares of Common
         Stock 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 shares of Common Stock are
         listed or admitted to trading or, if the shares of Common Stock are not
         listed or admitted to trading on any national securities exchange, the
         last quoted price or, if not so quoted, the average of the high bid and
         low asked prices in the over-the-counter market, as reported by the
         Nasdaq National Market ("Nasdaq") or such other system then in use, or,
         if on any such date the shares of Common Stock are not quoted by any
         such organization, the average of the closing bid and asked prices as
         furnished by a professional market maker making a market in the Common
         Stock selected by the Board of Directors of the Company. If on any such
         date no market maker is making a market in the Common Stock, the fair
         value of such shares on such date 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 shares of Common Stock are listed or admitted to trading is
         open for the transaction of business or, if the shares of Common Stock
         are not listed or admitted to trading on any national securities
         exchange, a Business Day. If the Common Stock is not publicly held or
         not so listed or traded, "current market price" per share shall mean
         the fair value per share as determined in good faith by the Board of
         Directors of the Company, whose determination shall be described in a
         statement filed with the Rights Agent and shall be conclusive for all
         purposes.

                  (ii) For the purpose of any computation hereunder, the
         "current market price" per share of Preferred Stock shall be determined
         in the same manner as set forth above for the Common Stock in clause
         (i) of this Section 11(d) (other than the last sentence thereof). If
         the current market price per share of Preferred Stock cannot be
         determined in the manner provided above or if the Preferred Stock is
         not publicly held or listed or traded in a manner described in clause
         (i) of this Section 11(d), the "current market price" per share of
         Preferred Stock shall be conclusively deemed to be an amount equal to
         1,000 (as such number may be appropriately adjusted for such events as
         stock splits, stock dividends and recapitalizations with respect to the
         Common Stock occurring after the date of this Agreement) multiplied by
         the


                                      -20-

<PAGE>


         current market price per share of the Common Stock. If neither the
         Common Stock nor the Preferred Stock is publicly held or so listed or
         traded, "current market price" per share of the Preferred Stock shall
         mean the fair value per share as determined in good faith by the Board
         of Directors of the Company, whose determination shall be described in
         a statement filed with the Rights Agent and shall be conclusive for all
         purposes. For all purposes of this Agreement, the "current market
         price" of one one-thousandth of a share of Preferred Stock shall be
         equal to the "current market price" of one share of Preferred Stock
         divided by 1,000.

                  (e) Anything herein to the contrary notwithstanding, no
adjustment in the Purchase Price shall be required unless such adjustment would
require an increase or decrease of at least one percent (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 hundred-millionth of a share
of Preferred Stock, or hundred- thousandth of a share of Common Stock or other
share, 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 (3) years from the date of the transaction which
mandates such adjustment, or (ii) the Expiration Date.

                  (f) If as a result of an adjustment made pursuant to Section
11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter exercised
shall become entitled to receive any shares of capital stock other than
Preferred Stock, thereafter the number of such other shares so receivable upon
exercise of any Right and the Purchase Price thereof shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Preferred Stock contained in
Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the
provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred
Stock shall apply on like terms to any such other shares.

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

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


                                      -21-

<PAGE>


(x) the number of one one-thousandths of a share covered by a Right immediately
prior to this adjustment, by (y) the Purchase Price in effect immediately prior
to such adjustment of the Purchase Price, and (ii) dividing the product so
obtained by the Purchase Price in effect immediately after such adjustment of
the Purchase Price.

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

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

                  (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then stated value, if any, of the number
of one


                                      -22-

<PAGE>



one-thousandths of a share of Preferred Stock 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 such number of fully paid and nonassessable one one-thousandths of a share
of fully paid and nonassessable Preferred Stock at such adjusted Purchase Price.

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

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

                  (n) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, (i) consolidate with any other Person (other
than a Subsidiary of the Company in a transaction that complies with Section
11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary
of the Company in a transaction which complies with Section 11(o) hereof), or
(iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one
transaction, or a series of related transactions, assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Company and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), if (x) at the time of or immediately after
such consolidation, merger or sale there are any rights, warrants or other
instruments or securities outstanding or agreements in effect that would
substantially diminish or otherwise eliminate the benefits intended to be


                                      -23-

<PAGE>


afforded by the Rights or (y) prior to, simultaneously with or immediately after
such consolidation, merger or sale, the shareholders of the Person who
constitutes, or would constitute, the "Principal Party" for purposes of Section
13(a) hereof shall have received a distribution of Rights previously owned by
such Person or any of its Affiliates and Associates. The Company shall not
consummate any such consolidation, merger, sale or transfer unless prior thereto
the Company and such other Person shall have executed and delivered to the
Rights Agent a supplemental agreement evidencing compliance with this Section
11(n).

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


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

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 or Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Common Stock, a copy of such certificate, and (c) mail a
brief summary thereof to each holder of a Rights Certificate (or, if prior to
the Distribution Date, to each holder of a certificate representing shares of
Common Stock) in accordance with Section 26 hereof. The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained and shall not be deemed to have knowledge of any adjustment unless and
until it shall have received such certificate.

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

                  (a) In the event that, at any time after a Person has become
an Acquiring Person, (x) the Company shall consolidate with, or merge with and
into, any other Person (other than a Subsidiary of the Company in a transaction
that complies with Section 11(o) hereof), and the Company shall not be the
continuing or surviving corporation of such consolidation or merger, (y) any
Person (other than a Subsidiary of the Company in a transaction that complies
with Section 11(o) hereof) shall consolidate with, or merge with or into, the
Company, and the Company shall be the continuing or surviving corporation of
such consolidation or merger and, in connection with such consolidation or
merger, all or part of the outstanding shares of Common Stock shall be changed
into or exchanged for stock or other securities of any other Person or cash or
any other property, or (z) the Company shall sell or otherwise transfer (or one
or more of its Subsidiaries shall sell or otherwise transfer), in one
transaction or a series of related transactions, assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more transactions each of which
complies with Section 11(o) hereof), then, and in each such case and except as
contemplated by Section 13(d) hereof, proper provision shall be made so that:
(i) each holder of a Right, except as provided in Section 7(e) hereof, shall
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price in accordance with the terms of this Agreement, such
number of validly authorized and issued, fully paid, non-assessable and freely
tradeable shares of Common Stock of the Principal Party (as such term is
hereinafter defined), not subject to any liens, encumbrances, rights of first
refusal or other adverse claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the number of one one-thousandths
of a share of Preferred Stock for which a Right is exercisable immediately prior
to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event
has occurred prior to the first occurrence of a Section 13 Event, multiplying
the number of such one one-thousandths of a share for which a Right was
exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event by the Purchase Price in effect immediately prior to such first
occurrence), and (2) dividing that product (which, following the first
occurrence of a Section 13 Event, shall be referred to as the "Purchase Price"
for each Right and for all purposes of this Agreement) by 50% of the current
market price (determined pursuant to Section 11(d)(i) hereof) per share of the
Common Stock of such Principal Party on the date of consummation of such Section
13 Event; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such Section 13 Event, all the obligations and duties of
the Company pursuant to this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of Section 11 hereof shall apply only to such
Principal Party following the first occurrence of a Section 13 Event; (iv) such
Principal


                                      -25-

<PAGE>


Party shall take such steps (including, but not limited to, the reservation of a
sufficient number of shares of its Common Stock) in connection with the
consummation of any such transaction as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to its shares of Common Stock thereafter deliverable upon the
exercise of the Rights; and (v) the provisions of Section 11(a)(ii) hereof shall
be of no effect following the first occurrence of any Section 13 Event.

                  (b) "Principal Party" shall mean

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

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

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding twelve (12)
month period registered under Section 12 of the Exchange Act, and such Person is
a direct or indirect Subsidiary of another Person the Common Stock of which is
and has been so registered, "Principal Party" shall refer to such other Person;
(2) in case such Person is a Subsidiary, directly or indirectly, of more than
one Person, the Common Stocks of two or more of which are and have been so
registered, "Principal Party" shall refer to whichever of such Persons is the
issuer of the Common Stock having the greatest aggregate market value; and (3)
in case such Person is owned, directly or indirectly, by a joint venture formed
by two or more Persons that are not owned, directly or indirectly, by the same
Person, the rules set forth in (1) and (2) above shall apply to each of the
chains of ownership having an interest in such joint venture as if such party
were a "Subsidiary" of both or all of such joint ventures and the Principal
Parties in each such chain shall bear the obligations set forth in this Section
13 in the same ratio as their direct or indirect interests in such Person bear
to the total of such interests.

                  (c) The Company shall not consummate any such consolidation,
merger, sale or transfer unless the Principal Party shall have a sufficient
number of authorized shares of its Common Stock which have not been issued or
reserved for issuance to permit the exercise in full of the Rights in accordance
with this Section 13 and unless prior thereto the Company and such Principal
Party shall have executed and delivered to the Rights Agent a supplemental
agreement providing for the terms


                                      -26-

<PAGE>


set forth in paragraphs (a) and (b) of this Section 13 and further providing
that, as soon as practicable after the date of any consolidation, merger or sale
of assets mentioned in paragraph (a) of this Section 13, the Principal Party
will

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

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

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

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

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

         Section 14.  Fractional Rights and Fractional Shares.

                  (a) The Company shall not be required to issue fractions of
Rights, except prior to the Distribution Date as provided in Section 11(i) or
11(p) hereof, or to distribute Rights Certificates that evidence fractional
Rights. In lieu of such fractional Rights, there shall be paid to the registered
holders of the Rights Certificates with


                                      -27-

<PAGE>


regard to which such fractional Rights would otherwise be issuable, an amount in
cash equal to the same fraction of the current market value of a whole Right.
For purposes of this Section 14(a), the current market value of a whole Right
shall be the closing price of the Rights for the Trading Day immediately prior
to the date on which such fractional Rights would have been otherwise issuable.
The closing price of the Rights for any day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of
the closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the 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 such 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
shares of Preferred Stock (other than fractions which are integral multiples of
one one-thousandth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates that evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock). In lieu of fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock), the Company shall pay to the registered holders of
Rights Certificates at the time such Rights are exercised as herein provided an
amount in cash equal to the same fraction of the current market value of one
one-thousandth of a share of Preferred Stock. For purposes of this Section
14(b), the current market value of one one-thousandth of a share of Preferred
Stock shall be one one-thousandth of the closing price of a share of Preferred
Stock (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day
immediately prior to the date of such exercise.

                  (c) Following the occurrence of a Triggering Event, the
Company shall not be required to issue fractions of shares of Common Stock upon
exercise of the Rights or to distribute certificates which evidence fractional
shares of Common Stock. In lieu of fractional shares of Common Stock, the
Company shall pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market


                                      -28-

<PAGE>


price of one (1) share of Common Stock (as determined pursuant to Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

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

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

         Section 16. Agreement of Rights Holders. Every holder of a Right by
accepting the same consents and agrees with the Company and the Rights Agent and
with every other holder of a Right that:

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

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

                  (c) subject to Section 6(a) and Section 7(f) hereof, the
Company and the Rights Agent may deem and treat the person in whose name a
Rights Certificate (or, prior to the Distribution Date, the associated Common
Stock certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or writing on the
Rights Certificates or the associated Common Stock certificate made by anyone
other than the Company or


                                      -29-

<PAGE>


the Rights Agent) for all purposes whatsoever, and neither the Company nor the
Rights Agent, subject to the last sentence of Section 7(e) hereof, shall be
required to be affected by any notice to the contrary; and

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

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

         Section 18.  Concerning the Rights Agent.

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


                                      -30-

<PAGE>


                  (b) The Rights Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate or certificate for Common Stock or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement, or other
paper or document believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged, by the proper Person or Persons, or
otherwise upon the advice of counsel as set forth in Section 20 hereof.

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

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

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

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


                                      -31-

<PAGE>


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

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person and
the determination of "current market price") be proved or established by the
Company prior to taking or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by a certificate signed by
the President, any Vice President, the Treasurer, any Assistant Treasurer, the
Secretary or any Assistant Secretary of the Company and delivered to the Rights
Agent; and such certificate shall be full 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 only for its
own gross negligence, bad faith or willful misconduct.

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

                  (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Rights Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any adjustment required under the provisions of
Section 11, Section 13 or Section 24 hereof or responsible for the manner,
method or amount of any such adjustment or the ascertaining of the existence of
facts that would require any such adjustment (except with respect to the
exercise of Rights evidenced by Rights Certificates after receipt of a
certificate describing any such adjustment, delivered pursuant to Section 12);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Common Stock or
Preferred Stock to be issued pursuant to this Agreement or any Rights
Certificate or as to whether any shares of Common Stock or Preferred Stock will,
when so issued, be validly authorized and issued, fully paid and nonassessable.

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

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

                  (h) The Rights Agent and any stockholder, 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, however, reasonable care was
exercised in the selection and continued employment thereof.

                  (j) No provision of this Agreement shall require the Rights
Agent to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder or in the exercise of its
rights if there shall


                                      -33-

<PAGE>


be reasonable grounds for believing that repayment of such funds or adequate
indemnification against such risk or liability is not reasonably assured to it.

                  (k) If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate attached to the form
of assignment or form of election to purchase, as the case may be, has not been
completed, the Company and the Rights Agent will deem the beneficial owner of
the Rights evidenced by such Rights Certificate to be an Acquiring Person or an
Affiliate or Associate thereof and such assignment or election to purchase will
not be honored.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty (30) days' notice in writing mailed to the Company, and to each
transfer agent of the Common Stock and Preferred Stock, by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) days' notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of the Common Stock
and Preferred Stock, by registered or certified mail, and, if such removal
occurs after the Distribution Date, to the holders of the Rights Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of thirty (30) days after giving notice of such removal or after it has
been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Rights Certificate (who shall,
with such notice, submit his Rights Certificate for inspection by the Company),
then any registered holder of any Rights Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be (a)
a corporation organized and doing business under the laws of the United States
(or of any state of the United States) in good standing, which is authorized
under such laws to exercise corporate trust or 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 $50,000,000 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 Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock and the Preferred Stock, and mail a notice thereof in writing
to the registered holders of the Rights Certificates. Failure to give any notice
provided for in this


                                      -34-

<PAGE>


Section 21, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement.

         Section 23.  Redemption and Termination.

                  (a) The Board of Directors of the Company may, at its option,
at any time prior to the earlier of (i) the close of business on the tenth day
following the Stock Acquisition Date (or, if the Stock Acquisition Date shall
have occurred prior to the Record Date, the close of business on the tenth day
following the Record Date) or (ii) the Final Expiration Date, redeem all but not
less than all the then outstanding Rights at a redemption price of $.01 per
Right, as such amount may be appropriately adjusted to reflect any stock split,
stock dividend or similar transaction occurring after the date hereof (such
redemption price being hereinafter referred to as the "Redemption Price"). The
redemption of the Rights by the Board may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish. Notwithstanding the foregoing if, following the
occurrence of a Stock Acquisition Date and following the expiration of the right
of redemption set forth above in this Section 23(a), either (i)(A) a Person who
is an Acquiring Person shall have transferred or otherwise disposed of a number
of shares of Common Stock in one transaction or series of transactions, not
directly or indirectly involving the Company or any of its Subsidiaries, such
that such Person is thereafter a Beneficial Owner of 10% or less of the
outstanding shares of Common Stock, and (B) there are no other Persons,
immediately following the occurrence of the event described in clause (A), who
are Acquiring Persons, and (C) there are at least two Continuing Directors then
in office and a majority of the Continuing Directors approve the reinstatement
of the right of redemption pursuant to this Section 23, or (ii)(A) the Board
approves the consolidation, merger or other combination of the Company with or
into, or the sale or other transfer (either by the Company or one or more of its
Subsidiaries), in one transaction or a series of related transactions, of more
than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole), to a Person other than the Acquiring Person (or any
Associate or Affiliate of such Acquiring Person) who caused the occurrence of
such Stock Acquisition Date, and (B) the Board of Directors of the Company, as
part of the approval of such an event described in the preceding clause (ii)(A),
approves the reinstatement of the right of redemption pursuant to this Section
23, and (C) there


                                      -35-

<PAGE>


are at least two Continuing Directors then in office and a majority of the
Continuing Directors so approve such reinstatement, then, in either such case,
the right of redemption shall be reinstated and thereafter be subject to the
provisions of this Section 23. Notwithstanding anything contained in this
Agreement to the contrary, the Rights shall not be exercisable after the first
occurrence of a Section 11(a)(ii) Event until such time as the Company's right
of redemption hereunder has expired.

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

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

         Section 24. Exchange.

                  (a) The Board of Directors of the Company may, at its option,
at any time after a Section 11(a)(ii) Event, exchange all or part of the then
outstanding and exercisable Rights (which (i) shall not include Rights that have
become void pursuant to the provisions of Section 7(e) hereof, and (ii) shall
include, without limitation, any Rights issued after the Distribution Date in
connection with the exercise of options pursuant to the Company's employee
benefit plans, where such option is exercised for securities of the Company or
surrendered for cash) for shares of Common Stock at an exchange ratio of one
share of Common Stock per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(such exchange ratio being hereinafter referred to as the "Exchange Ratio").
Notwithstanding the foregoing, the Board of Directors may effect such an
exchange


                                      -36-

<PAGE>


only if there are at least two Continuing Directors then in office and a
majority of such Continuing Directors concur with such exchange.

                  (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, evidence of which shall have been filed with the Rights Agent,
and without any further action and without any notice, the right to exercise
such Rights shall terminate and the only right thereafter of a holder of such
Rights shall be to receive that number of shares of Common Stock equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange. The Company promptly shall mail a notice
of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. 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 shall state the
method by which the exchange of shares of Common Stock for Rights will be
effected and, in the event of any partial exchange, the number of Rights which
will be exchanged. Any partial exchange shall be effected pro rata based on the
number of Rights (other than Rights which have become void pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights.

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

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

                  (e) The Company shall not be required to issue fractions of
shares of Common Stock or to distribute certificates which evidence fractional
shares of Common Stock. In lieu of such fractional shares of Common Stock, there
shall be paid to the registered holders of the Right Certificates with regard to
which such fractional shares of Common Stock would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
share of Common


                                      -37-

<PAGE>


Stock. For the purposes of this subsection (e), the current market value of a
whole share of Common Stock shall be the closing price per share of Common Stock
(as determined pursuant to the second sentence of Section 11(d)(i) hereof) for
the Trading Day immediately prior to the date of exchange pursuant to this
Section 24.

         Section 25. Notice of Certain Events.

                  (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), or (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares
of Preferred Stock or shares of stock of any class or any other securities,
rights or options, or (iii) to effect any reclassification of its Preferred
Stock (other than a reclassification involving only the subdivision of
outstanding shares of Preferred Stock), or (iv) to effect any consolidation or
merger into or with any other Person (other than a Subsidiary of the Company in
a transaction which complies with Section 11(o) hereof), or to effect any sale
or other transfer (or to permit one or more of its Subsidiaries to effect any
sale or other transfer), in one transaction or a series of related transactions,
of more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Company and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), or (v) to effect the liquidation,
dissolution or winding up of the Company, then, in each such case, the Company
shall give to each holder of a Rights Certificate, to the extent feasible and in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, distribution of
rights or warrants, or the date on which such reclassification, consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to take place
and the date of participation therein by the holders of the shares of Preferred
Stock, if any such date is to be fixed, and such notice shall be so given in the
case of any action covered by clause (i) or (ii) above at least twenty (20) days
prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action, at
least twenty (20) days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the shares of Preferred
Stock, whichever shall be the earlier.

                  (b) In case a Section 11(a)(ii) Event shall occur, then, in
any such case, (i) the Company shall as soon as practicable thereafter give to
each holder of a Rights Certificate, to the extent feasible and in accordance
with Section 26 hereof, a notice of the occurrence of such event, which shall
specify the event and the consequences of the event to holders of Rights under
Section 11(a)(ii) hereof, and


                                      -38-

<PAGE>


(ii) all references in the preceding paragraph to Preferred Stock shall be
deemed thereafter to refer also to Common Stock and/or, if appropriate, other
securities.

         Section 26. Notices. Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Rights Certificate
to or on the Company shall be sufficiently given or made if sent by first-class
mail, postage prepaid, addressed (until another address is filed in writing with

                            Attention: Account Manager

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Rights Certificate (or, if
prior to the Distribution Date, to the holder of certificates representing
shares of Common Stock) shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Company.

         Section 27. Supplements and Amendments. Except as provided in the
penultimate sentence of this Section 27, prior to the Distribution Date, the
Company may, in its sole and absolute discretion, and the Rights Agent shall, if
the Company so directs, supplement or amend any provision of this Agreement in
any respect without the approval of any holders of the Rights. At any time when
the Rights are no longer redeemable, except as provided in the penultimate
sentence of this Section 27, the Company may, and the Rights Agent shall, if the
Company so directs, supplement or amend this Agreement without the approval of
any holders of Rights in order (i) to cure any ambiguity, (ii) to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, (iii) to shorten or lengthen any time period
hereunder (which shortening or lengthening shall be effective only if there are
at least two Continuing Directors then


                                      -39-

<PAGE>


in office and shall require the concurrence of a majority of such Continuing
Directors), or (iv) to change or supplement the provisions hereunder in any
manner which the Company may deem necessary or desirable, provided that no such
supplement or amendment shall adversely affect the interests of the holders of
Rights as such (other than an Acquiring Person or an Affiliate or Associate of
an Acquiring Person); and provided further, that this Agreement may not be
supplemented or amended to lengthen, pursuant to clause (iii) of this sentence,
(A) a time period relating to when the Rights may be redeemed at such time as
the Rights are not then redeemable, or (B) any other time period unless such
lengthening is for the purpose of protecting, enhancing or clarifying the rights
of, and/or the benefits to, the holders of Rights. Upon the delivery of a
certificate from an appropriate officer of the Company which states that the
proposed supplement or amendment is in compliance with the terms of this Section
27, the Rights Agent shall execute such supplement or amendment. Notwithstanding
anything contained in this Agreement to the contrary, no supplement or amendment
shall be made which changes the Redemption Price, the Final Expiration Date, the
Purchase Price or the number of on one-thousands of a share of Preferred Stock
for which a Right is exercisable. Prior to the Distribution Date, the interests
of the holders of Rights shall be deemed coincident with the interests of the
holders of Common Stock.

         Section 28. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

administer this Agreement and to exercise all rights and powers specifically
granted to the Board or to the Company, or as may be necessary or advisable in
the administration of this Agreement, including, without limitation, the right
and power to (i) interpret the provisions of this Agreement, and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including a determination to redeem or not redeem the Rights or to
amend this Agreement). All such actions, calculations, interpretations and
determinations (including, for purposes of clause (y) below, all omissions with
respect to the foregoing) which are done or made by the Board in good faith,
shall (x) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Rights and all other parties, and (y) not subject the Board to
any liability to the holders of the Rights.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of the Common Stock) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights


                                      -40-

<PAGE>


Certificates (and, prior to the Distribution Date, registered holders of the
Common Stock).

         Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in

of counterparts and each of such counterparts shall for all purposes be deemed
to be an original, and all such counterparts shall together constitute but one
and the same instrument.

                             EIS INTERNATIONAL, INC.

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


         EIS International, Inc., a corporation organized and existing under the
laws of the State of Delaware (hereinafter called the "Corporation"), hereby
certifies that the following resolution was adopted by the Board of Directors of
the Corporation at a meeting duly called and held on May 16, 1997:

         RESOLVED: That pursuant to the authority granted to and vested in the
Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, as amended, the Board of Directors hereby creates a series of
Preferred Stock, $.01 par value (the "Preferred Stock"), of the Corporation and
hereby states the designation and number of shares, and fixes the relative
rights, preferences and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         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 fifteen thousand (15,000). Such number of shares may be increased
or decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

         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, par value $.01
per share (the "Common Stock"), of the Corporation, and of any other junior
stock, shall be entitled



<PAGE>


to receive, when, as and if declared by the Board of Directors out of funds of
the Corporation legally available for the payment of dividends, quarterly
dividends payable in cash on the last day of each fiscal quarter of the
Corporation in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Preferred Stock, in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $1.00 or (b) subject to the provision for adjustment
hereinafter set forth, 1,000 times the aggregate per share amount of all cash
dividends, and 1,000 times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions, other than a dividend payable in
shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision, combination or consolidation of
the outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the amount to which holders of
shares of Series A Preferred Stock were entitled immediately prior to such event
under clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event. In the event the Corporation shall at any time declare or pay any
dividend on the Series A Preferred Stock payable in shares of Series A Preferred
Stock, or effect a subdivision, combination or consolidation of the outstanding
shares of Series A Preferred Stock (by reclassification or otherwise than by
payment of a dividend in shares of Series A Preferred Stock) into a greater or
lesser number of shares of Series A Preferred Stock, then in each such case the
amount to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event under clause (b) of the first sentence of this
Section 2(A) shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Series A Preferred Stock that were
outstanding immediately prior to such event and the denominator of which is the
number of shares of Series A Preferred Stock outstanding immediately after such
event.

         (B) The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock) and the Corporation
shall pay such dividend or distribution on the Series A Preferred Stock before
the dividend or distribution declared on the Common Stock is paid or set apart;
provided that, in the event no


                                       -2-

<PAGE>


dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $1.00 per share on the 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 1,000
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision,
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. In the event the Corporation shall
at any time declare or pay any dividend on the Series A Preferred Stock payable
in shares of Series A Preferred Stock, or effect a subdivision, combination or
consolidation of the outstanding shares of Series A


                                       -3-

<PAGE>


Preferred Stock (by reclassification or otherwise than by payment of a dividend
in shares of Series A Preferred Stock) into a greater or lesser number of shares
of Series A Preferred Stock, then in each such case the number of votes per
share to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event shall be adjusted by multiplying such amount by
a fraction, the numerator of which is the number of shares of Series A Preferred
Stock that were outstanding immediately prior to such event and the denominator
of which is the number of shares of Series A Preferred Stock outstanding
immediately after such event.

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

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

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

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

                  (iv) If, during any interval between annual meetings of
stockholders for the election of Directors and while the holders of Series A
Preferred Stock shall be entitled to elect two Directors, there is no such
Director in office by reason of


                                       -4-

<PAGE>


resignation, death or removal, then, promptly thereafter, the Board of Directors
shall call a special meeting of the holders of Series A Preferred Stock for the
purpose of filling such vacancy and such vacancy shall be filled at such special
meeting. Such special meeting shall in any event be held within 45 days of the
occurrence of such vacancy.

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

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

         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 Corporation shall not:

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

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

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


                                       -5-

<PAGE>


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

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

         (B) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 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 Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

         Section 6. Liquidation, Dissolution or Winding Up.

         (A) Upon any liquidation, dissolution or winding up of the Corporation,
no distribution shall be made (1) to the holders of shares of stock ranking
junior (either as to dividends or upon liquidation, dissolution or winding up)
to the Series A Preferred Stock unless, prior thereto, the holders of shares of
Series A Preferred Stock shall have received $1,000 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
1,000 times the aggregate amount to be distributed per share to holders of
shares of Common Stock, or (2) to the holders of shares of stock ranking on a
parity (either as to dividends or upon liquidation, dissolution or winding up)
with the Series A Preferred Stock, except distributions made ratably on the
Series A Preferred Stock and all such parity stock in proportion


                                       -6-

<PAGE>


to the total amounts to which the holders of all such shares are entitled upon
such liquidation, dissolution or winding up.

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

         (C) In the event the Corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision, combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the aggregate amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event under the proviso
in clause (1) of paragraph (A) of this Section 6 shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. In the event the Corporation shall
at any time declare or pay any dividend on the Series A Preferred Stock payable
in shares of Series A Preferred Stock, or effect a subdivision, combination or
consolidation of the outstanding shares of Series A Preferred Stock (by
reclassification or otherwise than by payment of a dividend in shares of Series
A Preferred Stock) into a greater or lesser number of shares of Series A
Preferred Stock, then in each such case the aggregate amount to which holders of
shares of Series A Preferred Stock were entitled immediately prior to such event
under the proviso in clause (1) of paragraph (A) of this Section 4 shall be
adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of Series A Preferred Stock that were outstanding immediately
prior to such event and the denominator of which is the number of shares of
Series A Preferred Stock outstanding immediately after such event.

         Section 7. Consolidation, Merger, etc. Notwithstanding anything to the
contrary contained herein, in case the Corporation shall enter into any
consolidation, merger, combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each share of Series A
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 1,000 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a


                                       -7-

<PAGE>


subdivision, combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the amount set forth in the preceding sentence with respect to
the exchange or change of shares of Series A Preferred Stock shall be adjusted
by multiplying such amount by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. In the event the Corporation shall
at any time declare or pay any dividend on the Series A Preferred Stock payable
in shares of Series A Preferred Stock, or effect a subdivision, combination or
consolidation of the outstanding shares of Series A Preferred Stock (by
reclassification or otherwise than by payment of a dividend in shares of Series
A Preferred Stock) into a greater or lesser number of shares of Series A
Preferred Stock, then in each such case the amount set forth in the first
sentence of this Section 7 with respect to the exchange or change of shares of
Series A Preferred Stock shall be adjusted by multiplying such amount by a
fraction, the numerator of which is the number of shares of Series A Preferred
Stock that were outstanding immediately prior to such event and the denominator
of which is the number of shares of Series A Preferred Stock outstanding
immediately after such event.

         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 Preferred Stock issued either before or after the
issuance of the Series A Preferred Stock, unless the terms of any such series
shall provide otherwise.

         Section 10. Amendment. The Certificate of Incorporation, as amended, of
the Corporation 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.

         Section 11. Fractional Shares. Series A Preferred Stock may be issued
in fractions of a share which are integral multiples of one thousandth of a
share which shall entitle the holder, in proportion to such holder's fractional
shares, to exercise voting rights, receive dividends, participate in
distributions and have the benefit of all other rights of holders of Series A
Preferred Stock.

Purchase and related Certificate duly executed. The number of Rights evidenced
by this Rights Certificate (and the number of one one-thousandth of a share of
Preferred Stock which may be purchased upon exercise hereof) set forth above,
and the Purchase Price set forth above, are the number and Purchase Price as of
the close of business on May 27, 1997, based on the Preferred Stock as
constituted at such date. Capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed to such terms in the Rights
Agreement.

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

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

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the principal offices of the
Company and are available upon written request to the Company.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the office of the Rights Agent designated for such purpose,
with the Form of Election and Certificate set forth on the reverse side duly
executed, may be exchanged for another Rights Certificate or Rights Certificates
of like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of one one-thousandths of a share of Preferred Stock as the
Rights evidenced by the Rights Certificate or Rights Certificates surrendered
shall have entitled such holder to purchase. If this Rights Certificate shall be
exercised in part, the holder shall be


                                       -2-

<PAGE>


entitled to receive upon surrender hereof another Rights Certificate or Rights
Certificates for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate may be redeemed by the Company at its option at a redemption
price of $.01 per Right at any time prior to the earlier of (i) the close of
business on the tenth day following the Stock Acquisition Date or (ii) the Final
Expiration Date.

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

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

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

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

                                    EXHIBIT C
                                    ---------

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK

         On May 16, 1997, the Board of Directors of EIS International, Inc. (the
"Company"), declared a dividend of one preferred stock purchase right (a
"Right") for each outstanding share of the Company's Common Stock to
stockholders of record at the close of business on May 27, 1997 (the "Record
Date"). Each Right entitles the registered holder to purchase from the Company a
unit consisting of one one-thousandth of a share (a "Unit") of Series A Junior
Participating Preferred Stock, $.01 par value (the "Preferred Stock"), at a
purchase price of $20.00 in cash per Unit (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement dated as of May 16, 1997 (the "Rights Agreement") between the Company
and BankBoston, N.A., as Rights Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 20% or more of the outstanding shares of Common Stock (the "Stock
Acquisition Date"), or (ii) 10 business days following the commencement of a
tender offer or exchange offer that would result in a person or group
beneficially owning 20% or more of such outstanding shares of Common Stock.
Until the Distribution Date (or earlier redemption or expiration of the rights),
(i) the Rights will be evidenced by the Common Stock certificates and will be
transferred with and only with such Common Stock certificates, (ii) new Common
Stock certificates issued after the Record Date will contain a notation
incorporating the Rights Agreement by reference and (iii) the surrender for
transfer of any certificates for Common Stock outstanding, even without such
notation, will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate.

         The Rights are not exercisable until the Distribution Date and will
expire upon the earliest of the close of business on May 16, 2007 (the "Final
Expiration Date") or the redemption or exchange of the Rights as described
below.

         As soon as practicable after the Distribution Date, separate
certificates evidencing the Rights ("Rights Certificates") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date and, thereafter, such separate Rights Certificates alone will
represent the Rights. Except as otherwise determined by the Board of Directors
and except in connection with shares of Common Stock issued upon the exercise of
employee stock options, issuances under other employee stock benefit plans or
the conversion of convertible securities issued

hereafter, only shares of Common Stock issued prior to the Distribution Date
will be issued with Rights.

         In the event that any stockholder becomes an Acquiring Person, unless
the event causing the 20% threshold to be crossed is a Permitted Offer (as
defined in the Rights Agreement), then, promptly following the first occurrence
of such event, proper provision shall be made so that each holder of a Right
(except as provided below and in Section 7(e) of the Rights Agreement) shall
thereafter have the right to receive, upon exercise thereof at the then current
Purchase Price, in lieu of a number of one one-thousandths of a share of
Preferred Stock, such number of shares of Common Stock of the Company that
equals the result obtained by (x) multiplying the then current Purchase Price by
the then number of one one-thousandths of a share of Preferred Stock for which a
Right is then exercisable, and (y) dividing that product) by 50% of the current
market price per share of Common Stock on the date of such first occurrence.
Notwithstanding any of the foregoing, following the occurrence of the event set
forth in this paragraph, all Rights that are, or (under certain circumstances
specified in the Rights Agreement) were, beneficially owned by any Acquiring
Person will be null and void. The event set forth in this paragraph is referred
to as "Section 11(a)(ii) Event."

         For example, at an exercise price of $20.00 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following an event
set forth in the preceding paragraph would entitle its holder to purchase for
$20.00 such number of shares of Common Stock (or other consideration, as noted
above) as equals $20.00 divided by one-half of the current market price (as
defined in the Rights Agreement) of the Common Stock. Assuming that the Common
Stock had a per share value of $10.00 at such time, the holder of each valid
Right would be entitled to purchase four shares of Common Stock for $20.00.

         In the event that, at any time after any Person becomes an Acquiring
Person, (i) the Company is acquired in a merger or other business combination
transaction in which the Company is not the surviving corporation or its Common
Stock is changed or exchanged (other than a merger which follows a Permitted
Offer), or (ii) 50% or more of the Company's assets or earning power is sold or
transferred, each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, that number of shares of common stock of the acquiring company which
equals the exercise price of the Right divided by one-half of the current market
price of such common stock at the date of the occurrence of the event. The
events set forth in this paragraph are referred to as "Section 13 Events."
Section 11(a)(ii) Events and Section 13 Events are collectively referred to as
"Triggering Events."

         For example, at an exercise price of $20.00 per Right, each valid Right
following an event set forth in the preceding paragraph would entitle its holder
to

                                       -2-

<PAGE>


purchase for $20.00 such number of shares of common stock of the acquiring
company as equals $20.00 divided by one-half of the current market price (as
defined in the Rights Agreement) of such common stock. Assuming that such common
stock had a per share value of $10.00 at such time, the holder of each valid
Right would be entitled to purchase four shares of common stock of the acquiring
company for $20.00.

         At any time after the occurrence of a Section 11(a)(ii) Event, and
subject to certain the concurrence of a majority of the Continuing Directors (as
defined in the Rights Agreement), the Board of Directors of the Company may
exchange the Rights (other than Rights owned by such Acquiring Person which have
become void), in whole or in part, at an exchange ratio of one share of Common
Stock, or one one-thousandth of a share of Preferred Stock (or of a share of a
class or series of the Company's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

         The Purchase Price payable, and the number of Units of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) if holders of the Preferred Stock are granted certain
rights or warrants to subscribe for Preferred Stock or convertible securities at
less than the then-current market price of the Preferred Stock, or (iii) upon
the distribution to holders of the Preferred Stock of evidences of indebtedness
or assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings) or of subscription rights or warrants (other than those
referred to above).

         The number of Rights associated with each share of Common Stock is also
subject to adjustment in the event of a stock split of the Common Stock or a
stock dividend on the Common Stock payable in Common Stock or subdivisions,
consolidations or combinations of the Common Stock occurring, in any such case,
prior to the Distribution Date.

         Preferred Stock purchasable upon exercise of the Rights will not be
redeemable. Each share of Preferred Stock will be entitled to a minimum
preferential quarterly dividend payment of $1.00 per share and will be entitled
to an aggregate dividend of 1,000 times the dividend declared per share of
Common Stock. In the event of liquidation, the holders of the Preferred Stock
will be entitled to a minimum preferential liquidation payment of $1,000 per
share and will be entitled to an aggregate payment of 1,000 times the payment
made per share of Common Stock. Each share of Preferred Stock will have 1,000
votes, voting together with the Common Stock. Finally, in the event of any
merger, consolidation or other transaction in which Common Stock is exchanged,
each share of Preferred Stock will


                                       -3-

<PAGE>


be entitled to receive 1,000 times the amount received per share of Common
Stock. These rights are protected by customary antidilution provisions.

         Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of one one-thousandth of a share of Preferred Stock
purchasable upon exercise of each Right should approximate the value of one
share of Common Stock.

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. No fractional Rights will be issued and, in lieu thereof, an adjustment
in cash will be made based on the market price of the Preferred Stock on the
last trading date prior to the date of exercise.

         At any time prior to the earlier of (i) the close of business on the
tenth day following the Stock Acquisition Date, or (ii) the Final Expiration
Date, the Company may redeem the Rights in whole, but not in part, at a price of
$.01 per Right (the "Redemption Price"), payable in cash or stock. Immediately
upon the action of the Board of Directors ordering redemption of the Rights, the
Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

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

         Subject to certain exceptions, any of the provisions of the Rights
Agreement may be amended by the Board of Directors of the Company prior to the
Distribution Date.

         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-A dated
May 27, 1997. 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.
