THIS SHAREHOLDER RIGHTS PLAN is effective as of December 4, 1998, between
RealNetworks, Inc., a Washington corporation (the "CORPORATION"), and
ChaseMellon Shareholder Services, L.L.C. (the "RIGHTS AGENT").


                                   WITNESSETH

        WHEREAS, the Board of Directors of the Corporation has authorized and
declared a dividend of one preferred share purchase right (a "RIGHT") for each
Common Share (as hereinafter defined) of the Corporation outstanding at the
Close of Business on December 14, 1998 (the "RECORD DATE"), each Right
representing the right to purchase 1/1,000th of a Preferred Share (as
hereinafter defined), upon the terms and subject to the conditions herein set
forth, and has further authorized and directed the issuance of one Right with
respect to each Common Share that shall become outstanding between the Record
Date and the earliest of the Distribution Date, the Redemption Date or the Final
Expiration Date (as such terms are hereinafter defined); provided, however, that
Rights may be issued with respect to Common Shares that shall become outstanding
after the Distribution Date and prior to the earlier of the Redemption Date and
the Final Expiration Date in accordance with the provisions of Section 23 of
this Agreement.

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

          For purposes of this Agreement, the following terms have the meanings
indicated:

               (a)"ACQUIRING PERSON" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the then outstanding Common Shares (other
than as a result of a Permitted Offer) or was such a Beneficial Owner at any
time after the date hereof, whether or not such person continues to be the
Beneficial Owner of 15% or more of the then outstanding Common Shares.
Notwithstanding the foregoing, (A) the term "Acquiring Person" shall not include
(i) the Corporation, (ii) any Subsidiary of the Corporation, (iii) any employee
benefit plan of the Corporation or of any Subsidiary of the Corporation, (iv)
any Person or entity organized, appointed or established by the Corporation for
or pursuant to the terms of any such plan, (v) any Person, who or which together
with all Affiliates and Associates of such Person becomes the Beneficial Owner
of 15% or more of the then outstanding Common Shares as a result of the
acquisition of Common Shares directly from the Corporation or (vi) any
Grandfathered Shareholder, and (B) no Person shall be deemed to be an "Acquiring
Person" either (X) as a result of the acquisition of Common Shares by the
Corporation which, by reducing the number of Common Shares outstanding,
increases the proportional number of shares beneficially owned by such Person
together with all Affiliates and Associates of such Person; except that if (i) a
Person would become an Acquiring Person (but for the operation of this subclause
(X) as a result of the acquisition of Common Shares by the Corporation, and (ii)
after such share acquisition by the Corporation, such Person, or an Affiliate or
Associate of such Person, becomes the Beneficial Owner of any additional Common
Shares,


                                      -1-
<PAGE>   5

then such Person shall be deemed an Acquiring Person, or (Y) if (i)
within ten (10) days after such Person would otherwise have become an Acquiring
Person (but for the operation of this subclause (Y), such Person notifies the
Board of Directors that such Person did so inadvertently and (ii) within two (2)
days after such notification, such Person is the Beneficial Owner of less than
15% of the outstanding Common Shares.

               (b) "ACT" shall mean the Securities Act of 1933, as amended and
as in effect on the date of this Agreement.

               (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:

                    (1) which such Person or any of such Person's Affiliates or
Associates beneficially owns, directly or indirectly;

                    (2) which such Person or any of such Person's Affiliates or

immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding, or upon the exercise of conversion rights,
exchange rights, rights (other than the Rights), warrants or options, or
otherwise; provided, however, that a Person shall not be deemed the Beneficial
Owner of, or to beneficially own, securities tendered pursuant to a tender or
exchange offer made by or on behalf of such Person or any of such Person's
Affiliates or Associates until such tendered securities are accepted for
purchase or exchange; or (B) the right to vote pursuant to any agreement,
arrangement or understanding; provided, however, that a Person shall not be
deemed the Beneficial Owner of, or to beneficially own, any security if the
agreement, arrangement or understanding to vote such security (1) arises solely
from a revocable proxy or consent given to such Person in response to a public
proxy or consent solicitation made pursuant to, and in accordance with, the
applicable rules and regulations promulgated under the Exchange Act and (2) is
not also then reportable on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

                    (3) 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) relating to the acquisition, holding, voting (except to
the extent contemplated by the proviso to Section 1(d)(2)(B)) or disposing of
any securities of the Corporation.

the contrary, the phrase "then outstanding," when used with reference to a

number of such securities then issued and outstanding together with the number
of such securities not then actually issued and outstanding which such Person
would be deemed to own beneficially hereunder.

Common Shares on the date of this Agreement; provided that Robert Glaser shall
not be a Grandfathered Shareholder if he acquires additional Common Shares that
would increase his beneficial ownership to more than 14,075,521 Common Shares
(except for any acquisition of Common Shares by Mr. Glaser upon exercise of any
stock options granted to in connection with his employment with the
Corporation).

               (k) "INTERESTED SHAREHOLDER" shall mean any Acquiring Person or
any Affiliate or Associate of an Acquiring Person or any other Person in which
any such Acquiring Person, Affiliate or Associate has an interest, or any other

Affiliates, Associates, nominees or representatives of an Acquiring Person, to
be adequate (taking into account all factors that such Directors deem relevant

Corporation, any employee benefit plan of the Corporation or of any Subsidiary
of the Corporation or any Person or entity organized, appointed or established
by the Corporation for or pursuant to the terms of any such plan) of, or of the
first public announcement of the intention of any Person (other than the
Corporation, any Subsidiary of the Corporation, any employee benefit plan of the
Corporation or of any Subsidiary of the Corporation or any Person or entity
organized, appointed or established by the Corporation for or pursuant to the
terms of any such plan) to commence (which intention to commence remains in
effect for five (5) Business Days after such announcement), a tender or exchange
offer the consummation of which would result in any Person becoming an Acquiring
Person (including, in the case of both (i) and (ii), any such date which is
after the date of this Agreement and prior to the issuance of the Rights), the
earlier of such dates being herein referred to as the "DISTRIBUTION DATE," (x)
the Rights will be evidenced (subject to the provisions of Section 3(b) hereof)
by the certificates for Common Shares registered in the names of the holders
thereof (which certificates shall also be deemed to be Right Certificates) and
not by separate Right Certificates, and (y) the right to receive Right
Certificates will be transferable only in connection with the transfer of the
underlying Common Shares (including a transfer to the Corporation); provided,
however, that if a tender offer is terminated prior to the occurrence of a
Distribution Date, then no Distribution Date shall occur as a result of such
tender offer. As soon as practicable after the Distribution Date, the
Corporation will prepare and execute, the Rights Agent will countersign, and the
Corporation will send or cause to be sent by first-class, postage-prepaid mail,
to each record holder of Common Shares as of the Close of Business on the
Distribution Date, at the address of such holder shown on the records of the
Corporation, a Right Certificate, substantially in the form of Exhibit B hereto
(a "RIGHT CERTIFICATE"), evidencing one Right for each Common Share so held. As
of and after the Distribution Date, the Rights will be evidenced solely by such
Right Certificates.

               (b) As promptly as practicable following the Record Date, the
Corporation will send a copy of a Summary of Rights in substantially the form of
Exhibit C hereto (the "SUMMARY OF RIGHTS"), by first-class, postage-prepaid
mail, to each record holder of Common Shares as of


                                      -5-
<PAGE>   9

the Close of Business on the Record Date, at the address of such holder shown on
the records of the Corporation. With respect to certificates for Common Shares
outstanding as of the Record Date, until the Distribution Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together with a copy of the Summary of Rights attached thereto. Until the
Distribution Date (or the earlier of the Redemption Date or the Final Expiration
Date), the surrender for transfer of any certificate for Common Shares
outstanding on the Record Date, with or without a copy of the Summary of Rights
attached thereto, shall also constitute the transfer of the Rights associated
with such Common Shares.

               (c) Certificates for Common Shares which become outstanding
(including, without limitation, reacquired Common Shares referred to in the last
sentence of this paragraph (c)) after the Record Date but prior to the earliest
of the Distribution Date, the Redemption Date or the Final Expiration Date,
shall be deemed also to be certificates for Rights, and shall bear the following
legend:

        THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER HEREOF TO
        CERTAIN RIGHTS AS SET FORTH IN A SHAREHOLDER RIGHTS PLAN BETWEEN
        REALNETWORKS, INC. AND CHASEMELLON SHAREHOLDER SERVICES, L.L.C., DATED
        AS OF DECEMBER 4, 1998 (THE "RIGHTS PLAN"), THE TERMS OF WHICH ARE
        HEREBY INCORPORATED HEREIN BY REFERENCE AND A COPY OF WHICH IS ON FILE
        AT THE PRINCIPAL EXECUTIVE OFFICES OF REALNETWORKS, INC. UNDER CERTAIN
        CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS PLAN, SUCH RIGHTS WILL BE
        EVIDENCED BY SEPARATE CERTIFICATES AND WILL NO LONGER BE EVIDENCED BY
        THIS CERTIFICATE. REALNETWORKS, INC. WILL MAIL TO THE HOLDER OF THIS
        CERTIFICATE A COPY OF THE RIGHTS PLAN WITHOUT CHARGE AFTER RECEIPT OF A
        WRITTEN REQUEST THEREFOR. UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE
        RIGHTS PLAN, RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR
        BECOMES AN ACQUIRING PERSON OR AN AFFILIATE OR ASSOCIATE THEREOF (AS
        DEFINED IN THE RIGHTS PLAN) AND CERTAIN RELATED PERSONS, 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
Distribution Date, the Rights associated with the Common Shares represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Corporation purchases or acquires any Common Shares after the
Record Date but prior to the Distribution Date, any Rights associated with such
Common Shares shall be deemed cancelled and retired so that the Corporation
shall not be entitled to exercise any Rights associated with the Common Shares
which are no longer outstanding.

        Section 4. Form of Right Certificate.

               (a) The Right Certificates (and the forms of election to purchase
and of assignment to be printed on the reverse thereof) shall be substantially
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 Corporation may deem appropriate (but which do not affect the duties or
responsibilities of the Rights Agent) and as are not inconsistent with the
provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange 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 Right Certificates shall entitle the holders thereof
to purchase such number of 1/1,000th of a Preferred Share as shall be set forth
therein at the price per 1/1,000th of a Preferred Share set forth therein (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 Right Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights which are null and void pursuant to
Section 7(e) of this Agreement and any Right Certificate issued pursuant to
Section 6 or Section 11 hereof upon transfer, exchange, replacement or
adjustment of any other Right Certificate referred to in this sentence, shall
contain (to the extent feasible) the following legend:

        THE RIGHTS REPRESENTED BY THIS RIGHT CERTIFICATE ARE OR WERE
        BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN ACQUIRING PERSON OR
        AN AFFILIATE OR ASSOCIATE OF AN ACQUIRING PERSON (AS SUCH TERMS ARE
        DEFINED IN THE RIGHTS PLAN). ACCORDINGLY, THIS RIGHT CERTIFICATE AND THE
        RIGHTS REPRESENTED HEREBY ARE NULL AND VOID.

        Provisions of Section 7(e) of this Rights Plan shall be operative
whether or not the foregoing legend is contained on any such Right Certificate.

        Section 5. Countersignature and Registration. The Right Certificates
shall be executed on behalf of the Corporation by its Chairman of the Board, its
Chief Executive Officer, its President, Chief Financial Officer, any of its Vice
Presidents, or its Treasurer, either manually or by facsimile signature, shall
have affixed thereto the Corporation's seal or a facsimile thereof, and shall be
attested by the Secretary or an Assistant Secretary of the Corporation, either
manually or by facsimile signature. The Right Certificates shall be
countersigned by the Rights Agent and shall not be valid for any purpose unless
so countersigned. In case any officer of the Corporation who shall have signed
any of the Right Certificates shall cease to be such officer of the Corporation
before countersignature by the Rights Agent and issuance and delivery by the
Corporation, such Right Certificates may nevertheless be countersigned by the
Rights Agent and issued and delivered by the Corporation with the same force and
effect as though the person who


                                      -7-
<PAGE>   11

signed such Right Certificates had not ceased to be such officer of the
Corporation; and any Right Certificate may be signed on behalf of the
Corporation by any person who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Corporation to sign such Right
Certificate, although at the date of the execution of this Rights Plan any such
person was not such an officer.

        Following the Distribution Date and receipt of all necessary
information, the Rights Agent will keep or cause to be kept, at its principal
office or offices designated as the appropriate place for surrender of such
Right Certificate or transfer, books for registration and transfer of the Right
Certificates issued hereunder. Such books shall show the names and addresses of
the respective holders of the Right Certificates, the number of Rights evidenced
on its face by each of the Right Certificates and the certificate number and the
date of each of the Right Certificates.

        Section 6. Transfer, Split-Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificate. 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 earlier of the Redemption Date or the Final Expiration
Date, any Right Certificate or Right Certificates may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates,
entitling the registered holder to purchase a like number of 1/1,000ths of a
Preferred Share (or, following a Triggering Event, other securities, as the case
may be) as the Right Certificate or Right Certificates surrendered then entitled
such holder (or former holder in the case of a transfer) to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any Right
Certificate or Right Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Right Certificate or Right
Certificates to be transferred, split up, combined or exchanged at the principal
office or offices of the Rights Agent designated for such purpose. Neither the
Rights Agent nor the Corporation shall be obligated to take any action
whatsoever with respect to the transfer of any such surrendered Right
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Right Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Corporation or Rights Agent 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
Right Certificate or Right Certificates, as the case may be, as so requested.
The Corporation may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer, split
up, combination or exchange of Right Certificates.

        Upon receipt by the Corporation and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security satisfactory to them, and, at the Corporation's or Rights Agent's
request, reimbursement to the Corporation and the Rights Agent of all reasonable
expenses incidental thereto, and upon surrender to the Rights Agent and
cancellation of the Right Certificate if mutilated, the Corporation will make
and deliver a new Right Certificate of like


                                      -8-
<PAGE>   12

tenor to the Rights Agent for countersignature and delivery to the registered
holder in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

               (a) Subject to Section 7(e) hereof, the registered holder of any
Right Certificate may exercise the Rights evidenced thereby (except as otherwise
provided herein) in whole or in part at any time after the Distribution Date
upon surrender of the Right Certificate, with the form of election to purchase
and the certificate on the reverse side thereof duly executed, to the Rights
Agent at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price for the total
number of 1/1,000th of a Preferred Share (or other securities, as the case may
be) as to which such surrendered Rights are exercised, at or prior to the
earliest of (i) the Close of Business on December 4, 2008 (the "FINAL EXPIRATION
DATE"), or (ii) the time at which the Rights are redeemed as provided in Section
23 hereof (the "REDEMPTION DATE").

               (b) The Purchase Price for each 1/1,000th of a Preferred Share
pursuant to the exercise of a Right shall initially be $150.00, shall be subject
to adjustment from time to time as provided in the next sentence and in Sections
11 and 13(a) hereof and shall be payable in accordance with paragraph (c) below.
Anything in this Agreement to the contrary notwithstanding, in the event that at
any time after the date of this Agreement and prior to the Distribution Date,
the Corporation shall (i) declare or pay any dividend on the Common Shares
payable in Common Shares or (ii) effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares) into a greater or lesser number of Common
Shares, then in any such case, each Common Share outstanding following such
subdivision, combination or consolidation shall continue to have a Right
associated therewith and the Purchase Price following any such event shall be
proportionately adjusted to equal the result obtained by multiplying the
Purchase Price immediately prior to such event by a fraction the numerator of
which shall be the total number of Common Shares outstanding immediately prior
to the occurrence of the event and the denominator of which shall be the total
number of Common Shares outstanding immediately following the occurrence of such
event. The adjustment provided for in the preceding sentence shall be made
successively whenever such a dividend is declared or paid or such a subdivision,
combination or consolidation is effected.

               (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase and the certificate thereon duly
executed, accompanied by payment of the Purchase Price for the Preferred Shares
(or other securities, as the case may be) to be purchased and an amount equal to
any applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 6 hereof by certified check, cashier's
check or money order payable to the order of the Corporation, the Rights Agent
shall thereupon promptly (i) (A) requisition from any transfer agent of the
Preferred Shares certificates for the number of Preferred Shares to be purchased
and the Corporation hereby irrevocably authorizes its transfer agent to comply
with all such requests, or (B) if the Corporation, in its sole discretion, shall
have


                                      -9-
<PAGE>   13

elected to deposit the Preferred Shares issuable upon exercise of the
Rights hereunder into a depositary, requisition from the depositary agent
depositary receipts representing such number of 1/1,000th of a Preferred Share
as are to be purchased (in which case certificates for the Preferred Shares
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Corporation will direct the depositary agent to comply
with such requests, (ii) when appropriate, requisition from the Corporation the
amount of cash to be paid in lieu of issuance of fractional shares in accordance
with Section 14 hereof, (iii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Right Certificate, registered in such name or names as may be
designated by such holder, and (iv) when appropriate, after receipt thereof,
deliver such cash to or upon the order of the registered holder of such Right
Certificate. In the event that the Corporation is obligated to issue other
securities (including Common Shares) of the Corporation pursuant to Section
11(a) hereof, the Corporation will make all arrangements necessary so that such
other securities are available for distribution by the Rights Agent, if and when
necessary to comply with this Agreement.

        In addition, in the case of an exercise of the Rights by a holder
pursuant to Section 11(a)(ii), the Rights Agent shall return such Right
Certificate to the registered holder thereof after imprinting, stamping or
otherwise indicating thereon that the rights represented by such Right
Certificate no longer include the rights provided by Section 11(a)(ii) of the
Rights Plan and if less than all the Rights represented by such Right
Certificate were so exercised, the Rights Agent shall indicate on the Right
Certificate the number of Rights represented thereby which continue to include
the rights provided by Section 11(a)(ii).

               (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Right Certificate or to his
duly authorized assigns, subject to the provisions of Sections 6 and 14 hereof,
or the Rights Agent shall place an appropriate notation on the Right Certificate
with respect to those Rights exercised.

               (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 Affiliate or Associate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any Affiliate
or Associate thereof) who becomes a transferee after the Acquiring Person
becomes such, or (iii) a transferee of an Acquiring Person (or of any Affiliate
or Associate thereof) 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 a continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which the Board of Directors
of the Corporation has determined is part of a plan, arrangement or
understanding which has as a primary purpose or effect the avoidance of this
Section 7(e), shall become null and void without any further action and no
holder of such Rights shall have any rights whatsoever with respect to


                                      -10-
<PAGE>   14

such Rights, whether under any provision of this Agreement or otherwise. The
Corporation shall notify the Rights Agent when this Section 7(e) applies and
shall use all reasonable efforts to insure that the provisions of this Section
7(e) and Section 4(b) hereof are complied with, but neither the Company nor the
Rights Agent shall have any liability to any holder of Right Certificates or
other Person as a result of the Corporation's failure to make any determinations
with respect to an Acquiring Person or its Affiliates, Associates or transferees
hereunder.

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

        Section 8. Cancellation and Destruction of Right Certificates. All Right
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Corporation or to 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
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Rights Plan. The Corporation shall deliver to
the Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Corporation otherwise than upon the exercise thereof. The Rights Agent shall
deliver all cancelled Right Certificates to the Corporation, or shall, at the
written request of the Corporation, destroy such cancelled Right Certificates,
and in such case shall deliver a certificate of destruction thereof to the
Corporation.

        Section 9. Reservation and Availability of Preferred Shares. The
Corporation covenants and agrees that at all times prior to the occurrence of a
Section 11(a)(ii) Event it will cause to be reserved and kept available out of
its authorized and unissued Preferred Shares, or any authorized and issued
Preferred Shares held in its treasury, the number of Preferred Shares that will
be sufficient to permit the exercise in full of all outstanding Rights and,
after the occurrence of a Section 11(a)(ii) Event, shall, to the extent
reasonably practicable, so reserve and keep available a sufficient number of
Common Shares (and/or other securities) which may be required to permit the
exercise in full of the Rights pursuant to this Agreement.

        So long as the Preferred Shares (and, after the occurrence of a Section
11(a)(ii) Event, Common Shares or any other securities) issuable upon the
exercise of the Rights may be listed on any national securities exchange, the
Corporation 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.


                                      -11-
<PAGE>   15

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

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

        The Corporation shall use its best efforts to (i) file, as soon as
practicable following the Shares Acquisition Date, 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 and the rules and regulations thereunder)
until the date of the expiration of the rights provided by Section 11(a)(ii).
The Corporation will also take such action as may be appropriate under the blue
sky laws of the various states.

     Section 10. Preferred Shares Record Date. Each Person in whose name any
certificate for Preferred Shares (or Common Shares 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 the Preferred Shares (or Common
Shares and/or other securities, as the case may be) represented thereby on, and
such certificate shall be dated, the date upon which the Right Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer taxes) was made; provided, however, that, if the
date of such surrender and payment is a date upon which the Preferred Shares (or
Common Shares and/or other securities, as the case may be) transfer books of the
Corporation are closed, such Person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the Preferred Shares (or Common Shares and/or
other securities, as the case may be) transfer books of the Corporation are
open.


                                      -12-

        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 Corporation shall at any time after the
effective date of this Agreement (A) declare a dividend on the Preferred Shares
payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C)
combine the outstanding Preferred Shares into a smaller number of Preferred
Shares or (D) issue any shares of its capital stock in a reclassification of the
Preferred Shares (including any such reclassification in connection with a
consolidation or merger in which the Corporation 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 capital stock issuable on
such date, shall be proportionately adjusted so that the holder of any Right
exercised after such time shall be entitled to receive the aggregate number and
kind of shares of capital stock which, if such Right had been exercised
immediately prior to such date and at a time when the Preferred Shares transfer
books of the Corporation were open, such holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Corporation issuable
upon exercise of one Right. If an event occurs which would require an adjustment
under both Section 11(a)(i) and Section 11(a)(ii), 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).

               (ii) In the event any Person, alone or together with its
Affiliates and Associates, shall become an Acquiring Person, then proper
provision shall be made so that each holder of a Right (except as provided below
and in Section 7(e) hereof) shall, for a period of sixty (60) days after the
later of the occurrence of any such event or the effective date of an
appropriate registration statement under the Act pursuant to Section 9 hereof,
have a right to receive, upon exercise thereof at a price equal to the then
current Purchase Price, in accordance with the terms of this Agreement, such
number of Common Shares as shall equal the result obtained by (x) multiplying
the then current Purchase Price by the then number of 1/1,000th of a Preferred
Share for which a Right was exercisable immediately prior to the first
occurrence of a Section 11(a)(ii) Event, and dividing that product by (y) 50% of
the then current per share market price of the Corporation's Common Shares
(determined pursuant to Section 11(d) hereof) on the date of such first
occurrence (such number of shares being referred to as the "ADJUSTMENT SHARES");
provided, however, that if the transaction that would otherwise give rise to the
foregoing adjustment is also subject to the provisions of Section 13 hereof,
then only the provisions of Section 13 hereof shall apply and no adjustment
shall be made pursuant to this Section 11(a)(ii).


                                      -13-
<PAGE>   17

               (iii) In the event that there shall not be sufficient treasury
shares or authorized but unissued (and unreserved) Common Shares to permit the
exercise in full of the Rights in accordance with the foregoing subparagraph
(ii) and the Rights become so exercisable, notwithstanding any other provision
of this Agreement, to the extent necessary and permitted by applicable law, each
Right shall thereafter represent the right to receive, upon exercise thereof at
the then current Purchase Price in accordance with the terms of this Agreement,
(x) a number of (or fractions of) Common Shares (up to the maximum number of
Common Shares which may permissibly be issued) and (y) a number of (or fractions
of) other equity securities of the Corporation (or, in the discretion of the
Board of Directors, debt) including, but not limited to, fractions of a
Preferred Share, which the Board of Directors of the Corporation has determined
to have the same aggregate current market value (determined pursuant to Section
11(d)(i) and (ii) hereof, to the extent applicable) as one Common Share (such
number of (or fractions of) debt, or other equity securities or debt of the
Corporation being referred to as a "capital stock equivalent"), equal in the
aggregate to the number of Adjustment Shares; provided, however, if sufficient
Common Shares, and/or capital stock equivalents are unavailable, then the
Corporation shall, to the extent permitted by applicable law, take all such
action as may be necessary to authorize additional Common Shares or capital
stock equivalents for issuance upon exercise of the Rights, including the
calling of a meeting of shareholders; and provided, further, that if the
Corporation is unable to cause sufficient Common Shares and/or capital stock
equivalents to be available for issuance upon exercise in full of the Rights,
then each Right shall thereafter represent the right to receive the Adjusted
Number of Shares upon exercise at the Adjusted Purchase Price (as such terms are
hereinafter defined). As used herein, the term "ADJUSTED NUMBER OF SHARES" shall
be equal to that number of (or fractions of) Common Shares (and/or capital stock
equivalents) equal to the product of (x) the number of Adjustment Shares and (y)
a fraction, the numerator of which is the number of Common Shares (and/or
capital stock equivalents) available for issuance upon exercise of the Rights
and the denominator of which is the aggregate number of Adjustment Shares
otherwise issuable upon exercise in full of all Rights (assuming there were a
sufficient number of Common Shares available) (such fraction being referred to
as the "PRORATION FACTOR"). The "ADJUSTED PURCHASE PRICE" shall mean the product
of the Purchase Price and the Proration Factor. The Board of Directors may, but
shall not be required to, establish procedures to allocate the right to receive
Common Shares and capital stock equivalents upon exercise of the Rights among
holders of Rights.

          (b) In case the Corporation shall fix a record date for the issuance
of rights (other than the Rights), options or warrants to all holders of
Preferred Shares entitling them (for a period expiring within forty-five (45)
calendar days after such record date) to subscribe for or purchase Preferred
Shares (or shares having the same rights, privileges and preferences as the
Preferred Shares ("equivalent preferred shares")) or securities convertible into
Preferred Shares or equivalent preferred shares at a price per Preferred Share
or equivalent preferred share (or having a conversion price per share, if a
security convertible into Preferred Shares or equivalent preferred shares) less
than the then current per share market price of the Preferred Shares (as
determined pursuant to Section 11(d) hereof) 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


                                      -14-
<PAGE>   18

immediately prior to such record date by a fraction, the numerator of which
shall be the number of Preferred Shares outstanding on such record date plus the
number of Preferred Shares which the aggregate offering price of the total
number of Preferred Shares and/or equivalent preferred shares so to be offered
(and/or the aggregate initial conversion price of the convertible securities so
to be offered) would purchase at such current per share market price, and the
denominator of which shall be the number of Preferred Shares outstanding on such
record date plus the number of additional Preferred Shares and/or equivalent
preferred shares to be offered for subscription or purchase (or into which the
convertible securities so to be offered are initially convertible); provided,
however, that in no event shall the consideration to be paid upon the exercise
of one Right be less than the aggregate par value of the shares of capital stock
of the Corporation issuable upon exercise of one Right. In case such
subscription price may be paid in a consideration part or all of which shall be
in a form other than cash, the value of such consideration shall be determined
in good faith by the Board of Directors of the Corporation, whose determination
shall be described in a statement filed with the Rights Agent and shall be
binding on the Rights Agent. Preferred Shares owned by or held for the account
of the Corporation shall not be deemed outstanding for the purpose of any such
computation. Such adjustment shall be made successively whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

          (c) In case the Corporation shall fix a record date for the making of
a distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Corporation is the continuing or surviving corporation) of evidences of
indebtedness or assets (other than a regular quarterly cash dividend or a
dividend payable in Preferred Shares) or subscription rights or warrants
(excluding those referred to in Section 11(b) hereof), the Purchase Price to be
in effect after such record date shall be determined by multiplying the Purchase
Price in effect immediately prior to such record date by a fraction, the
numerator of which shall be the then current per share market price (as
determined pursuant to Section 11(d) hereof) of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Corporation, whose determination shall be described in
a statement filed with the Rights Agent and shall be binding on the Rights
Agent) of the portion of the assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to one
Preferred Share and the denominator of which shall be such current per share
market price of the Preferred Shares; provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Corporation to be
issued upon exercise of one Right. Such adjustments shall be made successively
whenever such a record date is fixed; and in the event that such distribution is
not so made, the Purchase Price shall again be adjusted to be the Purchase Price
which would then be in effect if such record date had not been fixed.

          (d) (i) For the purpose of any computation hereunder, the "current per
share market price" of any security (a "SECURITY" for the purpose of this
Section 11(d)(i)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the thirty (30) consecutive
Trading Days (as such term is hereinafter defined) immediately prior to


                                      -15-
<PAGE>   19

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

        (ii) For the purpose of any computation hereunder, the "current per
share market price" of the Preferred Shares shall be determined in accordance
with the method set forth in Section 11(d)(i). If the Preferred Shares are not
publicly traded, the "current per share market price" of the Preferred Shares
shall be conclusively deemed to be the current per share market price of the
Common Shares as determined pursuant to Section 11(d)(i) (appropriately adjusted
to reflect any stock split, stock dividend or similar transaction occurring
after the date hereof), multiplied by 1,000. If neither the Common Shares nor
the Preferred Shares are publicly held or so listed or traded, "current per
share market price" shall mean the fair value per share as determined in good
faith by the Board of Directors of the Corporation, whose determination shall be
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent.

               (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 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


                                      -16-
<PAGE>   20

cent or to the nearest 1/1,000th of a Preferred Share or one ten-thousandth of
any other share or security as the case may be. Notwithstanding the first
sentence of this Section 11(e), any adjustment required by this Section 11 shall
be made no later than the earlier of (i) three (3) years from the date of the
transaction which mandates such adjustment or (ii) the Final 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 of the Corporation
other than Preferred Shares, thereafter the number of other shares so receivable
upon exercise of any Right shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to the Preferred Shares contained in Section 11(a) through (c),
inclusive, and the provisions of Sections 7, 9, 10, 13 and 14 with respect to
the Preferred Shares shall apply on like terms to any such other shares.

               (g) All Rights originally issued by the Corporation subsequent to
any adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of 1/1,000th of a Preferred
Share purchasable from time to time hereunder upon exercise of the Rights, all
subject to further adjustment as provided herein.

               (h) The Corporation 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 1/1,000th of a Preferred Share purchasable upon the
exercise of a Right. Each of the Rights outstanding after such adjustment of the
number of Rights shall be exercisable for the number of 1/1,000th of a Preferred
Share for which a Right was exercisable immediately prior to such adjustment.
Each Right held of record prior to such adjustment of the number of Rights shall
become that number of Rights (calculated to the nearest one ten-thousandth)
obtained by dividing the Purchase Price in effect immediately prior to
adjustment of the Purchase Price by the Purchase Price in effect immediately
after adjustment of the Purchase Price. The Corporation shall make a public
announcement (with prompt notice thereof to the Rights Agent) of its election to
adjust the number of Rights, indicating the record date for the adjustment, and,
if known at the time, the amount of the adjustment to be made. This record date
may be the date on which the Purchase Price is adjusted or any day thereafter,
but, if the Right Certificates have been issued, shall be at least ten (10) days
later than the date of the public announcement. If Right Certificates have been
issued, upon each adjustment of the number of Rights pursuant to this Section
11(h), the Corporation shall, as promptly as practicable, cause to be
distributed to holders of record of Right Certificates on such record date Right
Certificates evidencing, subject to Section 14 hereof, the additional Rights to
which such holders shall be entitled as a result of such adjustment, or, at the
option of the Corporation, shall cause to be distributed to such holders of
record in substitution and replacement for the Right Certificates held by such
holders prior to the date of adjustment, and upon surrender thereof, if required
by the Corporation, new Right Certificates evidencing all the Rights to which
such holders shall be entitled after such adjustment. Right Certificates so to
be distributed shall be issued, executed and countersigned in


                                      -17-
<PAGE>   21

the manner provided for herein and shall be registered in the names of the
holders of record of Right Certificates on the record date specified in the
public announcement.

               (i) Irrespective of any adjustment or change in the Purchase
Price or the number of 1/1,000th of a Preferred Share issuable upon the exercise
of the Rights, the Right Certificates theretofore and thereafter issued may
continue to express the Purchase Price and the number of 1/1,000th of a
Preferred Share which were expressed in the initial Right Certificates issued
hereunder.

               (j) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the number of
1/1,000th of a Preferred Share, Common Shares or other securities issuable upon
exercise of the Rights, the Corporation shall take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Corporation
may validly and legally issue such number of fully paid and non-assessable
1/1,000th of a Preferred Share, Common Shares or other securities at such
adjusted Purchase Price.

               (k) 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 Corporation may elect to defer (with prompt notice thereof
to the Rights Agent) until the occurrence of such event the issuance to the
holder of any Right exercised after such record date the Preferred Shares,
Common Shares or other securities of the Corporation, if any, issuable upon such
exercise over and above the Preferred Shares, Common Shares or other securities
of the Corporation, if any, issuable upon exercise on the basis of the Purchase
Price in effect prior to such adjustment; provided, however, that the
Corporation shall deliver to such holder a due bill or other appropriate
instrument evidencing such holder's right to receive such additional shares upon
the occurrence of the event requiring such adjustment.

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

               (m) The Corporation 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 Corporation in a transaction which does not
violate Section 11(n) hereof), (ii) merge with or into any other Person (other
than a Subsidiary of the Corporation in a transaction which does not violate
Section 11(n) 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


                                      -18-
<PAGE>   22

than 50% of the assets or earning power of the Corporation and its Subsidiaries
(taken as a whole) to any other Person or Persons (other than the Corporation
and/or any of its Subsidiaries in one or more transactions each of which does
not violate Section 11(n) hereof), if (x) at the time of or immediately after
such consolidation, merger, sale or transfer there are any charter or by-law
provisions or any rights, warrants or other instruments or securities
outstanding or agreements in effect or other actions taken, which would
materially diminish or otherwise eliminate the benefits intended to be afforded
by the Rights or (y) prior to, simultaneously with or immediately after such
consolidation, merger or sale, the 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 Corporation shall not consummate any
such consolidation, merger, sale or transfer unless prior thereto the
Corporation and such other Person shall have executed and delivered to the
Rights Agent a supplemental agreement evidencing compliance with this Section
11(m).

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

               (o) The exercise of Rights under Section 11(a)(ii) shall only
result in the loss of rights under Section 11(a)(ii) to the extent so exercised
and shall not otherwise affect the rights represented by the Rights under this
Rights Plan, including the rights represented by Section 13.

        Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 or 13 hereof, the
Corporation shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts and computations accounting for
such adjustment, (b) file with the Rights Agent and with each transfer agent for
the Common Shares and the Preferred Shares a copy of such certificate and (c)
mail a brief summary thereof to each holder of a Right Certificate in accordance
with Section 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 such adjustment unless and until it shall have
received such certificate.

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

               (a) In the event that, on or following the Shares Acquisition
Date, directly or indirectly, (x) the Corporation shall consolidate with, or
merge with and into, any Person, (y) the Corporation shall consolidate with, or
merge with, any Person, and the Corporation shall be the continuing or surviving
corporation of such consolidation or merger (other than, in a case of any
transaction described in (x) or (y), a merger or consolidation which would
result in all of the securities generally entitled to vote in the election of
directors ("VOTING SECURITIES") of the Corporation outstanding immediately prior
thereto, continuing to represent (either by remaining


                                      -19-
<PAGE>   23

outstanding or by being converted into securities of the surviving entity) all
of the voting securities of the Corporation or such surviving entity outstanding
immediately after such merger or consolidation and the holders of such
securities not having changed as a result of such merger or consolidation), or
(z) the Corporation 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 Corporation and its Subsidiaries (taken as a
whole) to any Person, then, and in each such case (except as provided in 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 a price equal to the then current
Purchase Price, in accordance with the terms of this Agreement and in lieu of
Preferred Shares, such number of freely tradeable Common Shares of the Principal
Party (as hereinafter defined), not subject to any liens, encumbrances, rights
of first refusal or other adverse claims, as shall equal the result obtained by
(A) multiplying the then current Purchase Price by the number of 1/1,000th of a
Preferred Share for which a Right is then exercisable (without taking into
account any adjustment previously made pursuant to Section 11(a)(ii)) and
dividing that product by (B) 50% of the then current per share market price of
the Common Shares of such Principal Party (determined pursuant to Section 11(d)
hereof) on the date of consummation of such 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 Corporation
pursuant to this Agreement; (iii) the term "Corporation" 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; and (iv) such Principal
Party shall take such steps (including, but not limited to, the reservation of a
sufficient number of its Common Shares) in connection with the consummation of
any such transaction as may be necessary to assure that the provisions hereof
shall thereafter be applicable, as nearly as reasonably may be, in relation to
the Common Shares thereafter deliverable upon the exercise of the Rights.

               (b) "PRINCIPAL PARTY" shall mean:

                    (1) 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 Common Shares of the Corporation 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 (including, if applicable, the
Corporation if it is the surviving corporation); and

                    (2) 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 of the foregoing
cases, (1) if the Common Shares of such Person are not at such time and have 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 Shares of which are and have 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


                                      -20-
<PAGE>   24

Person, the Common Shares of two or more of which are and have been so
registered, "Principal Party" shall refer to whichever of such Persons is the
issuer of the Common Shares having the greatest aggregate market value; and (3)
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 venturers and the Principal
Parties in each such chain shall bear the obligations set forth in this Section
13 in the same ratio as their direct or indirect interests in such Person bear
to the total of such interests.

               (c) The Corporation shall not consummate any such consolidation,
merger, sale or transfer unless the Principal Party shall have a sufficient
number of its authorized Common Shares which have not been issued or reserved
for issuance to permit the exercise in full of the Rights in accordance with
this Section 13 and unless prior thereto the Corporation and such Principal
Party shall have executed and delivered to the Rights Agent a supplemental
agreement providing for the terms set forth in paragraphs (a) and (b) of this
Section 13 and further providing that, as soon as practicable after the date of
any consolidation, merger, sale or transfer mentioned in paragraph (a) of this
Section 13, the Principal Party at its own expense shall:

                    (1) 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 Final Expiration Date;

                    (2) 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

                    (3) deliver to holders of the Rights historical financial
statements for the Principal Party which 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. The rights under this
Section 13 shall be in addition to the rights to exercise Rights and adjustments
under Section 11(a)(ii) and shall survive any exercise thereof.

               (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 who acquired Common Shares pursuant to a Permitted Offer (or a
wholly owned Subsidiary of any such Person or Persons); (ii) the price per
Common Share offered in such transaction is not less than the price per Common
Share paid to all holders of Common Shares whose shares were purchased pursuant
to such


                                      -21-
<PAGE>   25

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

               (b) The Corporation shall not be required to issue fractions of
Preferred Shares (other than fractions which are 1/1,000th or integral multiples
of 1/1,000th of a Preferred Share) upon exercise of the Rights or to distribute
certificates which evidence fractional Preferred Shares (other than fractions
which are 1/1,000th or integral multiples of 1/1,000th of a Preferred Share).
Fractions of Preferred Shares in integral multiples of 1/1,000th of a Preferred
Share may, at the election of the Corporation, be evidenced by depositary
receipts, pursuant to an appropriate agreement between the Corporation and a
depositary selected by it; provided that such agreement shall provide that the
holders of such depositary receipts shall have the rights, privileges and
preferences to which they are entitled as beneficial owners of the Preferred
Shares represented by such depositary receipts. In lieu of fractional Preferred
Shares that are not 1/1,000th or integral multiples of 1/1,000th of a Preferred
Share, the Corporation shall pay to the registered holders of Right Certificates
at the time such Rights are exercised as herein provided an amount in cash equal
to the same fraction of the current market value of one Preferred Share. For the
purposes of this Section 14(b), the current market value of a Preferred Share
shall be the closing price of a


                                      -22-
<PAGE>   26

Preferred Share (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 one of the transactions or events
specified in Section 11 giving rise to the right to receive Common Shares,
capital, stock equivalents (other than Preferred Shares) or other securities
upon the exercise of a Right, the Corporation shall not be required to issue
fractions of shares or units of such Common Shares, capital stock equivalents or
other securities upon exercise of the Rights or to distribute certificates which
evidence fractions of such Common Shares, capital stock equivalents or other
securities. In lieu of fractional shares or units of such Common Shares, capital
stock equivalents or other securities, the Corporation may pay to the registered
holders of Right Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of a share or unit of such Common Shares, capital stock equivalents or
other securities. For purposes of this Section 14(c), the current market value
shall be determined in the manner set forth in Section 11(d) hereof for the
Trading Day immediately prior to the date of such exercise and, if such capital
stock equivalent is not traded, each such capital stock equivalent shall have
the value of 1/1,000th of a Preferred Share.

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

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

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

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


                                      -23-
<PAGE>   27

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

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

               (d) notwithstanding anything in this Agreement to the contrary,
neither the Corporation nor the Rights Agent shall have any liability to any
holder of a Right or a beneficial interest in a Right or other Person as a
result of its inability to perform any of its obligations under this Agreement
by reason of any preliminary or permanent injunction or other order, decree,
judgment or ruling 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 Corporation must use its best efforts to have any such
order, decree or ruling lifted or otherwise overturned as soon as possible.

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

        Section 18. Concerning the Rights Agent. The Corporation agrees to pay
to the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the preparation,
execution, delivery and amendment of this Agreement and the exercise and
performance of its duties hereunder. The Corporation also agrees to indemnify
the Rights Agent for, and to hold it harmless against, any loss, liability,
damage, judgment, fine, penalty, claim, demand, settlement, cost or expense,
incurred without gross


                                      -24-
<PAGE>   28

negligence, bad faith or willful misconduct on the part of the Rights Agent, for
any action taken, supplied 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. The
indemnity provided for herein shall survive the expiration of the Rights and the
termination of this Agreement and the costs and expenses incurred in enforcing
this right of indemnification shall be paid by the Corporation.

        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 acceptance and administration of this Agreement in reliance upon any Right
Certificate or certificate for Common Shares or for other securities of the
Corporation, 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.

        Anything in this Agreement to the contrary notwithstanding, in no event
shall the Rights Agent be liable for special, punitive, indirect, incidental or
consequential loss or damage of any kind whatsoever (including, but not limited
to lost profits), even if the Rights Agent has been advised of the likelihood of
such loss or damage and regardless of the form of action.

        Section 19. Merger or Consolidation or Change of Name of Rights Agent.
Any Person into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any Person resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any Person succeeding to the 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 that such Person
would be eligible for appointment as a successor Rights Agent under the
provisions of Section 21 hereof. In case at the time such successor Rights Agent
shall succeed to the agency created by this Agreement, any of the Right
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of a predecessor Rights Agent and
deliver such Right Certificates so countersigned; and in case at that time any
of the Right Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Right Certificates either in the name of the
predecessor or in the name of the successor Rights Agent; and in all such cases
such Right Certificates shall have the full force provided in the Right
Certificates and in this Agreement.

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


                                      -25-
<PAGE>   29

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

               (a) The Rights Agent may consult with legal counsel (who may be
legal counsel for the Corporation), and the advice or 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
advice or opinion.

               (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of an Acquiring Person and
the determination of the current market price of any Security) be proved or
established by the Corporation prior to taking or suffering or omitting to take
any action hereunder, such fact or matter (unless other evidence in respect
thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by any one of the Chairman of the
Board, the Chief Executive Officer, the President, Chief Financial Officer, any
Vice President, the Treasurer or the Secretary of the Corporation and delivered
to the Rights Agent; and such certificate shall be full authorization and
protection to the Rights Agent for any action taken, omitted 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
Right Certificates (except its countersignature on such Right Certificates) or
be required to verify the same, but all such statements and recitals are and
shall be deemed to have been made by the Corporation only.

               (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Corporation of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming null and void pursuant to Section 7(e) hereof) or
any adjustment required under the provisions of Section 11 or Section 13 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 Right Certificates
after receipt of the certificate described in Section 12 hereof); nor shall it
by any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares or Common Shares to be
issued pursuant to this Agreement or any Right Certificate or as to


                                      -26-
<PAGE>   30

whether any Preferred Shares or Common Shares will, when issued, be validly
authorized and issued, fully paid and non-assessable.

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

               (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Treasurer or the Secretary of the Corporation, and to
apply to such officers for advice or instructions in connection with its duties,
and shall not be liable for any action taken, omitted to be taken or suffered by
it in good faith or lack of action in accordance with instructions of any such
officer or for any delay in acting while waiting for those instructions. Any
application by the Rights Agent for written instructions from the Corporation
may, at the option of the Rights Agent, set forth in writing any action proposed
to be taken or omitted by the Rights Agent under this Rights Plan and the date
on or after which such action shall be taken or such omission shall be
effective. The Rights Agent shall not be liable for any action taken by, or
omission of, the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date shall
not be less than five Business Days after the date any officer of the
Corporation actually receives such application, unless any such officer shall
have consented in writing to an earlier date) unless, prior to taking any such
action (or the effective date in the case of an omission), the Rights Agent
shall have received written instruction in response to such application
specifying the action to be taken or omitted.

               (h) The Rights Agent and any shareholder, affiliate, director,
officer or employee of the Rights Agent may buy, sell or deal in any of the
Rights or other securities of the Corporation or become pecuniarily interested
in any transaction in which the Corporation may be interested, or contract with
or lend money to the Corporation 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 Corporation or for any
other Person.

               (i) The Rights Agent may execute and exercise any of the rights
or powers hereby vested in it or perform any duty hereunder either itself 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 Corporation resulting from any such act,
default, neglect or misconduct, provided 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 be reasonable grounds for believing that


                                      -27-
<PAGE>   31

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 Rights Agent shall not take any further action with respect to
such requested exercise of transfer without first consulting with the
Corporation.

        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 Corporation and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Corporation may remove the Rights Agent or any successor Rights Agent
upon sixty (60) days' notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of the Common
Shares or Preferred Shares by registered or certified mail, and to holders of
the Right Certificates by first-class mail. If the Rights Agent shall resign or
be removed or shall otherwise become incapable of acting, the Corporation shall
appoint a successor to the Rights Agent. If the Corporation shall fail to make
such appointment within a period of sixty (60) days after giving notice of such
removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Corporation), then the registered holder of any Right
Certificate may apply to any court of competent jurisdiction for the appointment
of a new Rights Agent. Any successor Rights Agent, whether appointed by the
Corporation or by such a court, shall be (i) a Person organized and doing
business under the laws of the United States or of the State of California (or
of any other state of the United States so long as such corporation is
authorized to do business in the State of California), in good standing, having
an office in the State of California, which is authorized under such laws to
exercise 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 (ii) an
affiliate of such Person. 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 Corporation shall file
notice thereof in writing with the predecessor Rights Agent and each transfer
agent of the Common Shares or Preferred Shares, and mail a notice thereof in
writing to the registered holders of the Right Certificates. Failure to give any
notice provided for in this Section 21, however, or any defect therein, shall
not affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

        Section 22. Issuance of New Right Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the
Corporation may, at its option, issue new Right Certificates evidencing Rights
in such form as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Agreement. In addition, in
connection with the issuance or sale of Common Shares following the Distribution
Date and prior to the earlier of the Redemption Date and the Final Expiration
Date, the Corporation (a) shall with respect to Common Shares so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement, or upon the exercise, conversion or exchange of securities, notes
or debentures issued by the Corporation, and (b) may, in any other case, if
deemed necessary, or appropriate by the Board of Directors of the Corporation,
issue Right Certificates representing the appropriate number of Rights in
connection with such issuance or sale; provided, however, that (i) the
Corporation shall not be obligated to issue any such Right Certificates if, and
to the extent that, the Corporation shall be advised by counsel that such
issuance would create a significant risk of material adverse tax consequences to
the Corporation or the Person to whom such Right Certificate would be issued,
and (ii) no Right Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

        Section 23. Redemption and Termination.

               (a) (i) The Board of Directors of the Corporation may, at its
option, redeem all but not less than all the then outstanding Rights at a
redemption price of $0.01 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"), at any time prior to the earlier of (x)
the occurrence of a Section 11(a)(ii) Event, or (y) the Final Expiration Date.
The Corporation may, at its option, pay the Redemption Price either in Common
Shares (based on the "current per share market price," as defined in Section
11(d) hereof, of the Common Share at the time of redemption) or cash; provided
that if the Corporation elects to pay the Redemption Price in Common Shares, the
Corporation shall not be required to issue any fractional Common Shares and the
number of Common Shares issuable to each holder of Rights shall be rounded down
to the next whole share.

               (ii) In addition, the Board of Directors of the Corporation may,
at its option, at any time following the occurrence of a Section 11(a)(ii) Event
and the expiration of any period during which the holder of Rights may exercise
the rights under Section 11(a)(ii) but prior to any Section 13 Event redeem all
but not less than all of the then outstanding Rights at the Redemption Price (x)
in connection with any merger, consolidation or sale or other transfer (in one
transaction or in a series of related transactions) of assets or earning power
aggregating 50% or more of the earning power of the Corporation and its
subsidiaries (taken as a whole) in which all holders of Common Shares are
treated alike and not involving (other than as a holder of Common Shares being
treated like all other such holders) an Interested Shareholder or (y)(aa) if


                                      -29-
<PAGE>   33

and for so long as the Acquiring Person is not thereafter the Beneficial Owner
of 50% of the Common Shares, and (bb) at the time of redemption no other Persons
are Acquiring Persons.

               (b) Notwithstanding the provisions of Section 23(a), in the event
that a majority of the Board of Directors of the Corporation is comprised of (i)
persons elected at a meeting of or by written consent of shareholders who were
not nominated by the Board of Directors in office immediately prior to such
meeting or action by written consent, and/or (ii) successors of such persons,
then the Rights may not be redeemed for a period of one hundred twenty (120)
days following the effectiveness of such election.

               (c) In the case of a redemption permitted under Section 23(a)(i),
immediately upon the date for redemption set forth (or determined in the manner
specified in) in a resolution of the Board of Directors of the Corporation
ordering the redemption of the Rights, evidence of which shall have been filed
with the Rights Agent, and without any further action and without any notice,
the right to exercise the Rights will terminate and the only right thereafter of
the holders of Rights shall be to receive the Redemption Price for each Right so
held. In the case of a redemption permitted only under Section 23(a)(ii),
evidence of which shall have been filed with the Rights Agent, the right to
exercise the Rights will terminate and represent only the right to receive the
Redemption Price upon the later of ten (10) Business Days following the giving
of such notice or the expiration of any period during which the rights under
Section 11(a)(ii) may be exercised. The Corporation shall promptly give public
notice of any such redemption; provided, however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within ten (10) days after such date for redemption set forth in a resolution of
the Board of Directors ordering the redemption of the Rights, the Corporation
shall mail a notice of redemption to all the holders of the then outstanding
Rights at their last addresses as they appear upon the registry books of the
Rights Agent or, prior to the Distribution Date, on the registry books of the
transfer agent for the Common Shares. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of redemption will state the method by which the
payment of the Redemption Price will be made. Neither the Corporation nor any of
its Affiliates or Associates may redeem, acquire or purchase for value any
Rights at any time in any manner other than that specifically set forth in this
Section 23 and other than in connection with the purchase of Common Shares prior
to the Distribution Date.

               (d) The Corporation 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


                                      -30-
<PAGE>   34

accordance with this Agreement (with prompt notice thereof to the Rights Agent)
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 Corporation.

        Section 24. Exchange.

               (a) The Board of Directors of the Corporation may, at its option,
at any time after any Person becomes an Acquiring Person, exchange all or part
of the then outstanding and exercisable Rights (which shall not include Rights
that have become void pursuant to the provisions of Section 11(a)(ii) hereof)
for Common Shares of the Corporation at an exchange ratio of one Common Share
per Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "EXCHANGE RATIO"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Corporation, any Subsidiary of the
Corporation, any employee benefit plan of the Corporation, or any such
Subsidiary, any entity holding Common Shares for or pursuant to the terms of any
such a plan), together with all Affiliates and Associates of such Person,
becomes the Beneficial Owner of 50% or more of the Common Shares then
outstanding.

               (b) Immediately upon the action of the Board of Directors of the
Corporation ordering the exchange of any Rights pursuant to Section 24(a) and
without any further action and without any notice, the right to exercise such
Rights shall terminate and the only right thereafter of the holders of such
Rights shall be to receive that number of Common Shares equal to the number of
such Rights held by such holder multiplied by the Exchange Ratio. The
Corporation 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 Corporation shall promptly mail a
notice of any such exchange to the Rights Agent and to all of the holders of
such Rights at their last addresses as they appear upon the registry books of
the Rights Agent. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of exchange will state the method by which the exchange of the Common Shares for
Rights will be effected and, in the event of any partial exchange, the number of
Rights which will be exchanged. Any partial exchange shall be effected pro rata
based on the number of Rights (other than Rights which have become null and void
pursuant to the provisions of Section 11(a)(ii) hereof) held by each holder of
Rights.

               (c) In any exchange pursuant to this Section 24, the Corporation,
at its option, may substitute Preferred Shares (or equivalent preferred shares,
as such term is defined in Section 11(b) hereof) for some or all of the Common
Shares exchangeable for Rights, at the initial rate of 1/1,000th of a Preferred
Share (or equivalent preferred share) for each Common Share, as appropriately
adjusted to reflect adjustments in the voting rights of the Preferred Shares


                                      -31-
<PAGE>   35

pursuant to the terms thereof, so that the fraction of a Preferred Share
delivered in lieu of each Common Share shall have the same voting rights as one
Common Share.

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

        Section 25. Notice of Certain Events.

               (a) In case the Corporation shall propose (i) to pay any dividend
payable in stock of any class to the holders of its Preferred Shares or to make
any other distribution to the holders of its Preferred Shares (other than a
regularly quarterly cash dividend), (ii) to offer to the holders of its
Preferred Shares rights or warrants to subscribe for or to purchase any
additional Preferred Shares or shares of stock of any class or any other
securities, rights or options, (iii) to effect any reclassification of its
Preferred Shares (other than a reclassification involving only the subdivision
of outstanding Preferred Shares), (iv) to effect any consolidation or merger
into or with any other Person (other than a Subsidiary of the Corporation in a
transaction which does not violate Section 11(n) 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 or more transactions, of 50% or more of the
assets or earning power of the Corporation and its Subsidiaries (taken as a
whole) to any other Person or Persons (other than the Corporation and/or any of
its Subsidiaries in one or more transactions each of which does not violate
Section 11(n) hereof), or (v) to effect the liquidation, dissolution or winding
up of the Corporation, then, in each such case, the Corporation shall give to
each holder of a Right Certificate, in accordance with Section 26 hereof, a
notice of such proposed action to the extent feasible and file a certificate
with the Rights Agent to that effect, which shall specify the record date for
the purposes of such stock dividend, or distribution of rights or warrants, or
the date on which such reclassification, consolidation, merger, sale, transfer,
liquidation, dissolution, or winding up is to take place and the date of
participation therein by the holders of the Preferred Shares, if any such date
is to be fixed, and such notice shall be so given in the case of any action
covered by clause (i) or (ii) above at least twenty (20) days prior to the
record date for determining holders of the Preferred Shares for purposes of such
action, and in the case of any such other action, at least 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 Preferred Shares, whichever shall be
the earlier.

               (b) In case of a Section 11(a)(ii) Event, then (i) the
Corporation shall as soon as practicable thereafter give to each holder of a
Right Certificate, in accordance with Section 26 hereof, a notice of the
occurrence of such event, which notice shall describe such event and the
consequences of such event to holders of Rights under Section 11(a)(ii) hereof,
and (ii) all references in the preceding paragraph (a) to Preferred Shares shall
be deemed thereafter to refer also to Common Shares and/or, if appropriate,
other securities of the Corporation.

        Section 26. Notices. Notices or demands authorized by this Agreement to

writing with the Rights Agent) as follows:

                      Attention: General Counsel

        Subject to the provisions of Section 21 hereof, any notice or demand
authorized by this Agreement to be given or made by the Corporation or by the
holder of any Right Certificate to or on the Rights Agent shall be sufficiently

                      Seattle, WA  98101
                      Attention:  Tom Cooper

        Notices or demands authorized by this Agreement to be given or made by
the Corporation of the Rights Agent to the holder of any Right Certificate or,
if prior to the Distribution Date, to the holder of certificates representing
Common Shares 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 Corporation.

        Section 27. Supplements and Amendments. Prior to the Distribution Date,
the Corporation and the Rights Agent shall, if the Corporation so directs,
supplement or amend any provision of this Agreement without the approval of any
holders of certificates representing Common Shares. From and after the
Distribution Date, the Corporation and the Rights Agent shall, if the
Corporation so directs, supplement or amend this Agreement without the approval
of any holders of Right Certificates 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 or (iv) to change or supplement the provisions hereunder
in any manner which the Corporation may deem necessary or desirable and which
shall not adversely affect the interests of the holders of Right Certificates
(other than an Acquiring Person or an Affiliate or Associate of an Acquiring
Person); provided, however, 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 Corporation 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, provided that such


                                      -33-
<PAGE>   37

supplement or amendment does not adversely affect the rights or obligations of
the Rights Agent under this Agreement. Prior to the Distribution Date, the
interests of the holders of Rights shall be deemed coincident with the interests
of the holders of Common Shares. Notwithstanding anything contained in this
Rights Plan to the contrary, in the event that a majority of the Board of
Directors of the Corporation is comprised of (i) persons elected at a meeting of
or by written consent of shareholders and who were not nominated by the Board of
Directors in office immediately prior to such meeting or action by written
consent and/or (ii) successors of such persons, then for a period of one
hundred twenty (120) days following the effectiveness of such election, this
Rights Plan shall not be amended or supplemented in any manner by the
Corporation during such one hundred twenty (120) day period except to the
extent the Corporation and Rights Agent could amend or supplement the Rights
Plan following the Distribution Date.

        Section 28. Determination and Actions by the Board of Directors, etc.
The Board of Directors of the Corporation shall have the exclusive power and
authority to administer this Agreement and to exercise all rights and powers
specifically granted to the Board, or the Corporation, 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, without limitation, a
determination to redeem or not redeem the Rights or to amend the Agreement and
whether any proposed amendment adversely affects the interests of the holders of
Right Certificates). For all purposes of this Agreement, any calculation of the
number of Common Shares or other securities outstanding at any particular time,
including for purposes of determining the particular percentage of such
outstanding Common Shares or any other securities 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 as in
effect on the date of 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 Corporation,
the Rights Agent, the holders of the Right Certificates and all other Persons,
and (y) not subject the Board to any liability to the holders of the Right
Certificates. The Rights Agent is entitled to always assume the Corporation's
Board of Directors acted in good faith and shall be fully protected and incur no
liability in reliance thereon.

        Section 29. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Corporation or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

        Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any person or corporation other than the Corporation,
the Rights Agent and the registered holders of the Right Certificates (and,
prior to the Distribution Date, the Common Shares) any legal or equitable right,
remedy or claim under this Agreement; but this Agreement


                                      -34-
<PAGE>   38

shall be for the sole and exclusive benefit of the Corporation, the Rights Agent
and the registered holders of the Right Certificates (and, prior to the
Distribution Date, the Common Shares).

        Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

        Section 32. Governing Law. This Agreement, each Right and each Right
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts to
be made and performed entirely within such State; provided, however, that all
provisions regarding the rights, duties and obligations of the Rights Agent
shall be governed by and construed in accordance with the laws of the State of
New York applicable to contracts made and to be performed entirely within such
State.

        Section 33. Counterparts. This Agreement may be executed in any number
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.

        Section 34. Descriptive Headings. Descriptive headings of the several
Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                           OF SERIES A PREFERRED STOCK



        Pursuant to the authority granted to and vested in the Board of
Directors of RealNetworks, Inc., a Washington corporation (the "CORPORATION"),
in accordance with the provisions of the Corporation's Restated Articles of
Incorporation, the Board of Directors hereby establishes a series of the
Corporation's Preferred Stock, par value $0.001, consisting of 200,000 shares
designated Series A Preferred Stock, and hereby states the designation and
number of shares, and fixes the relative rights, preferences and limitations
thereof (in addition to the provisions in the Restated Articles of Incorporation
which are applicable to the Preferred Stock of all classes and series) as
follows:

               SECTION 1. Designation and Amount. The shares of such series
shall be designated as "SERIES A PREFERRED STOCK." The Series A Preferred Stock
shall have a par value of $0.001 per share, and the number of shares
constituting such series shall be 200,000.

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

               SECTION 3. Dividends and Distributions.

               (a) Subject to the prior and superior right of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series A Preferred Stock with respect to dividends, the holders of shares of
Series A Preferred Stock shall be entitled to receive when, as and if declared
by the Board of Directors out of funds legally available for that purpose,
quarterly dividends payable in cash on the last day of January, April, July and
October 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 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 (except as provided in Section 2 hereof) 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.

<PAGE>   41

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

               (c) Dividends shall begin to accrue on outstanding shares of
Series A Preferred Stock from the Quarterly Dividend Payment Date next preceding
the date of issue of such shares of Series A Preferred Stock, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue from such Quarterly
Dividend Payment Date. Accrued but unpaid dividends shall not bear interest.
Dividends paid on the shares of Series A 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 no more than 30 days prior to the date fixed for the payment
thereof.

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

               (a) 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
shareholders of the Corporation.

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

               (c) Except as required 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 5. Certain Restrictions.

               (a) The Corporation shall not declare any dividend on, make any
distribution on, or redeem or purchase or otherwise acquire for consideration
any shares of Common Stock after the first issuance of a share or fraction of a
share of Series A Preferred Stock unless concurrently therewith it shall declare
a dividend on the Series A Preferred Stock as required by Section 3 hereof.

<PAGE>   42

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

                    (ii) declare or pay dividends on, make any other
distributions on any shares of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with Series A 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 on a parity (either as to dividends or
rights upon liquidation, dissolution or winding up) with the Series A Preferred
Stock, provided that the Corporation may at any time redeem, purchase or
otherwise acquire shares of any such parity stock in exchange for shares of any
stock of the Corporation ranking junior (either as to dividends or upon
dissolution, liquidation or winding up) to the Series A Preferred Stock; and

                    (iv) 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.

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

               SECTION 6. Reacquired Shares. Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

<PAGE>   43

               SECTION 7. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Series A Preferred Stock shall be entitled to receive an aggregate amount per
share equal to 1,000 times the aggregate amount to be distributed per share to
holders of shares of Common Stock plus an amount equal to any accrued and unpaid
dividends on such shares of Series A Preferred Stock.

               SECTION 8. Consolidation, Merger, etc. In case the Corporation
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case the shares
of Series A Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share equal to 1,000 times the aggregate amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or
exchanged.

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

               SECTION 10. Ranking. The Series A Preferred Stock shall rank
junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise or as otherwise may be required by
applicable law.

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

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

                               REALNETWORKS, INC.


                                Summary of Rights

The summary below sets forth certain principal terms of the preferred share
purchase rights only and is qualified in its entirety by reference to the
detailed terms of the Shareholder Rights Plan dated December 4, 1998, between
the Company and ChaseMellon Shareholder Services, L.L.C. The Shareholder Rights
Plan was filed as an exhibit to the Company's Registration Statement on Form
8-A12G filed with the Securities and Exchange Commission on December 11, 1998.
The Securities and Exchange Commission maintains an Internet web site at
http://www.sec.gov where the text of the Shareholder Rights Plan may be viewed
and/or downloaded.

Distribution Date

Prior to the Distribution Date referred to below, the Rights are evidenced by
and trade with the Common Stock certificates only. After the Distribution Date,
the Company will mail Rights certificates to the Company's shareholders and the
Rights will become transferable apart from the Common Stock. The Rights will
separate from the Common Stock and become exercisable following (a) the first
date of public announcement that an Acquiring Person has become such ("Shares
Acquisition Date") or (b) the tenth day (or such later date as may be determined
by the Board of Directors) after a person or group announces a tender or
exchange offer, the consummation of which would result in ownership by a person
or group of 15% or more of the Company's outstanding Common Stock.

Preferred Stock Purchasable Upon Exercise of Rights

After the Distribution Date, each Right will entitle the holder to purchase for
$150.00 (the "Exercise Price"), a fraction of a share of the Company's Series A
Preferred Stock with economic terms similar to that of one share of the
Company's Common Stock.

Flip-In Events

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


<PAGE>   53

Flip-Over Events

If, after an Acquiring Person obtains 15% or more of the Company's Common Stock,
(a) the Company merges into another entity, (b) an acquiring entity merges into
the Company or (c) the Company sells more than 50% or more of the Company's
assets or earning power, then each Right (other than Rights owned by an
