                                RIGHTS AGREEMENT


        This Rights Agreement ("Rights Agreement"), is dated as of November 8,
2000, between Virage, Inc., a Delaware corporation (the "Company"), and
Continental Stock Transfer & Trust Company (the "Rights Agent").

                              W I T N E S S E T H:

        WHEREAS, the Board of Directors of the Company on November 8, 2000 (i)
authorized the issuance and declared a dividend of one right ("Right") for each
share of the common stock of the Company ("Common Stock") outstanding as of the
Close of Business (as such term is hereinafter defined) on December 5, 2000 (the
"Record Date"), each Right representing the right to purchase one one-thousandth
of a share of Series A Preferred Stock of the Company having the rights, powers
and preferences set forth in the form of Certificate of Designation attached
hereto as Exhibit A upon the terms and subject to the conditions hereinafter set
forth, and (ii) further authorized the issuance of one Right with respect to
each share of Common Stock of the Company that shall become outstanding between
December 5, 2000 and the Distribution Date (as such term is hereinafter
defined);

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

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

                (a) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, without the prior approval of the Board of Directors, shall be the
Beneficial Owner (as such term is hereinafter defined) of fifteen percent (15%)
or more of the outstanding Common Stock; provided, however, that in no event
shall a Person who or which, together with all Affiliates and Associates of such
Person, is the Beneficial Owner of less than 15% of the Company's outstanding
shares of Common Stock, become an Acquiring Person solely as a result of a
reduction of the number of shares of outstanding Common Stock, including
repurchases of outstanding shares of Common Stock by the Company, which
reduction increases the percentage of outstanding shares of Common Stock
beneficially owned by such Person, provided, however, that if a Person shall
become the Beneficial Owner of 15% or more of the Company's outstanding shares
of Common Stock then outstanding solely by reason of a reduction of the number
of shares of outstanding Common Stock, and shall thereafter become the
Beneficial Owner of any additional shares of Common Stock of the Company, then
such Person shall be deemed to be an "Acquiring Person" unless upon the
consummation of the acquisition of such additional shares of Common Stock such
person does not own fifteen percent (15%) or more of the shares of Common Stock
then outstanding, and provided further, that an Acquiring Person shall not
include an Exempt Person (as such term is hereinafter defined). Notwithstanding
the foregoing, if the Board of Directors of the Company determines in good faith
that a Person who would otherwise be an "Acquiring Person," as defined pursuant
to the foregoing provisions of this paragraph (a), has become such inadvertently
(including, without limitation, because (i) such Person was unaware that it



<PAGE>   5

beneficially owned a percentage of Common Stock that would otherwise cause such
Person to be an "Acquiring Person" or (ii) such Person was aware of the extent
of its Beneficial Ownership but had no actual knowledge of the consequences of
such Beneficial Ownership under this Agreement) and without any intention of
changing or influencing control of the Company, and such Person divests as
promptly as practicable a sufficient number of shares of Common Stock so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), then such Person shall not be deemed
to be or to have become an "Acquiring Person" for any purposes of this
Agreement.

                (b) "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 ("Exchange
Act"), as in effect on the date of this Agreement.

                (c) A Person shall be deemed the "Beneficial Owner" of any
securities

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

                        (ii) which such Person or any of such Person's
Affiliates or Associates, directly or indirectly, has (A) the right to acquire
(whether such right is exercisable immediately or only after the passage of
time) pursuant to any agreement, arrangement or understanding (other than
customary agreements with and between underwriters and selling group members
with respect to a bona fide public offering of securities), whether or not in
writing, 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 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 or
dispose of or has "beneficial ownership" of (as determined pursuant to Rule
13d-3 of the General Rules and Regulations under the Exchange Act, or any
comparable or successor rule), including pursuant to any agreement, arrangement
or understanding (whether or not in writing); provided, however, that a Person
shall not be deemed the "Beneficial Owner" of, or to "beneficially own", any
securities if the agreement, arrangement or understanding to vote such security
(1) arises solely from a revocable proxy or consent given in response to a
public proxy or consent solicitation made pursuant to, and in accordance with,
the applicable rules and regulations of the Exchange Act and (2) is not also
then reportable by such Person on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

                        (iii) which are beneficially owned, directly or
indirectly, by any other Person with which such Person or any of such Person's
Affiliates or Associates has any agreement, arrangement or understanding
(whether or not in writing) for the purpose of acquiring, holding, voting except
as described in clause (B) of subparagraph (ii) of this Section 1(c) or
disposing of any securities of the Company; provided, however, that no Person
who is an officer, director or employee of an Exempt Person shall be deemed,
solely by reason of such Person's status or authority as such, to be the
"Beneficial Owner" of, to have "Beneficial Ownership" of or to "beneficially
own" any securities that are "beneficially owned" (as defined



                                       2
<PAGE>   6

in this Section 1(c)), including, without limitation, in a fiduciary capacity,
by an Exempt Person or by any other such officer, director or employee of an
Exempt Person.

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

Business Day it shall mean 5:00 P.M., Eastern time, on the next succeeding
Business Day.

mean the common stock of the Company. "Common Stock" when used with reference to
any Person other than the Company which shall be organized in corporate form
shall mean the capital stock or other equity security with the greatest per
share voting power of such Person or, if such Person is a Subsidiary of or is
controlled by another Person, the Person which ultimately controls such
first-mentioned Person. "Common Stock" when used with reference to any Person
other than the Company which shall not be organized in corporate form shall mean
units of beneficial interest which shall represent the right to participate in
profits, losses, deductions and credits of such Person and which shall be
entitled to exercise the greatest voting power per unit of such Person.

<PAGE>   9

which such Person, together with its Affiliates and Associates, would be the
Beneficial Owner of 15% or more of the outstanding Common Stock (irrespective of
whether any shares are actually purchased pursuant to any such offer) (including
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(c) hereof) by the certificates for the Common Stock
registered in the names of the holders of the Common Stock and not by separate
Right Certificates, and (y) each Right will be transferable only in connection
with the transfer of a share (subject to adjustment as hereinafter provided) of
Common Stock. As soon as practicable after the Distribution Date, the Rights
Agent will mail, at the expense of the Company, by first-class, postage prepaid
mail, to each record holder of the Common Stock as of the Close of Business on
the Distribution Date, as shown by the records of the Company, to the address of
such holder shown on such records, a Right certificate in substantially the form
of Exhibit B hereto ("Right Certificate") evidencing one Right for each share of
Common Stock so held. As of and after the Distribution Date, the Rights will be
evidenced solely by such Right Certificates.

                (b) On the Record Date, or as soon as practicable thereafter,
the Company will send a copy of a Summary of Rights to Purchase Preferred Stock,
substantially in the form attached hereto as Exhibit C ("Summary of Rights"), by
first-class, postage prepaid mail, to each record holder of Common Stock as of
the Close of Business on the Record Date, at the address of such holder shown on
the records of the Company.

                (c) Rights shall be issued in respect of all shares of Common
Stock that are issued (either as an original issuance or from the Company's
treasury) after the Record Date prior to the earlier of the Distribution Date or
the Expiration Date. With respect to certificates representing such shares of
Common Stock, the Rights will be evidenced by such certificates for Common Stock
registered in the names of the holders thereof together with the Summary of
Rights. Until the Distribution Date (or, if earlier, the Expiration Date), the
surrender for transfer of any certificate for Common Stock outstanding on the
Record Date (with or without a copy of the Summary of Rights attached thereto),
shall also constitute the surrender for transfer of the Rights associated with
the Common Stock represented thereby.

                (d) Certificates issued for Common Stock (including, without
limitation, certificates issued upon transfer or exchange of Common Stock) after
the Record Date but prior to the earlier of the Distribution Date or the
Expiration Date shall have impressed on, printed on, written on or otherwise
affixed to them the following legend:

        This certificate also evidences and entitles the holder hereof to
        certain Rights as set forth in the Rights Agreement between Virage, Inc.
        and Continental Stock Transfer & Trust Company, as Rights Agent, dated
        as of November 8, 2000, as the same may be amended from time to time
        (the "Rights Agreement"), the terms of which are incorporated herein by
        reference and a copy of which is on file at the principal executive
        office of Virage, Inc. Under certain circumstances, as set forth in the
        Rights Agreement, such Rights will be evidenced by separate certificates
        and will no longer be evidenced by this certificate. Virage, Inc. will
        mail to the holder of this certificate a copy of the Rights Agreement
        without charge after receipt by it of a written request therefor. UNDER
        CERTAIN



                                       6
<PAGE>   10

        CIRCUMSTANCES, AS PROVIDED IN THE RIGHTS AGREEMENT, RIGHTS ISSUED TO,
        BENEFICIALLY OWNED BY OR TRANSFERRED TO ANY PERSON WHO IS OR BECOMES AN
        ACQUIRING PERSON (AS DEFINED IN THE RIGHTS AGREEMENT) OR AN ASSOCIATE OR
        AFFILIATE (AS DEFINED IN THE RIGHTS AGREEMENT) THEREOF AND CERTAIN
        TRANSFEREES THEREOF WILL BE NULL AND VOID AND WILL NO LONGER BE
        TRANSFERABLE.

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

        Notwithstanding this paragraph (d), the omission of a legend shall not
affect the enforceability of any part of this Agreement or the rights of any
holder of the Rights.

        4. Form of Right Certificates.

                (a) The Right Certificates (and the forms of election to
purchase shares and of assignment to be printed on the reverse thereof), when,
as and if issued, shall be substantially in the form set forth in Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Rights
Agreement, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Rights may from time to time be listed, or to conform to
usage. Subject to the provisions of Sections 11, 13 and 22 hereof, the Right
Certificates evidencing the Rights issued on the Record Date whenever such
certificates are issued, shall be dated as of the Record Date and the Right
Certificates evidencing Rights to holders of record of Common Stock issued after
the Record Date shall be dated as of the Record Date but shall also be dated to
reflect the date of issuance of such Right Certificate. On their face, Right
Certificates shall entitle the holders thereof to purchase, for each Right, one
one-thousandth of a share of Preferred Stock, or other securities or property as
provided herein, as the same may from time to time be adjusted as provided
herein, at the price per one one-thousandth of a share of Preferred Stock of
$100.00, as the same may from time to time be adjusted as provided herein (the
"Purchase Price").

                (b) Notwithstanding any other provision of this Rights
Agreement, any Right Certificate that represents Rights that are or were at any
time on or after the earlier of the Stock Acquisition Date or the Distribution
Date beneficially owned by an Acquiring Person or any Affiliate or Associate
thereof (or any transferee of such Rights) shall have impressed on, printed on,
written on or otherwise affixed to it (if the Company or the Rights Agent has
knowledge that



                                       7
<PAGE>   11

such Person is an Acquiring Person or an Associate or Affiliate thereof or
transferee of such Persons or a nominee of any of the foregoing) the following
legend:

        The beneficial owner of the Rights represented by this Right Certificate
        is an Acquiring Person or an Affiliate or Associate (as defined in the
        Rights Agreement) of an Acquiring Person or a subsequent holder of such
        Right Certificates beneficially owned by such Persons. Accordingly, this
        Right Certificate and the Rights represented hereby are null and void
        and will no longer be transferable as provided in the Rights Agreement.

The provisions of Section 11(a)(ii) and Section 24 of this Rights Agreement
shall be operative whether or not the foregoing legend is contained on any such
Right Certificates.

        5. Countersignature and Registration.

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

                (b) Following the Distribution Date, the Rights Agent will keep
or cause to be kept, at one of its offices designated for such purposes, records
for registration and transfer of the Right Certificates issued hereunder. Such
records 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, the date of each of the Right Certificates and the
certificate numbers for each of the Right Certificates.

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

                (a) Subject to the provisions of Sections 7(e), 11(a)(ii) and 14
hereof, at any time after the Close of Business on the Distribution Date and at
or prior to the Close of Business on the Expiration Date, any Right Certificate
or Certificates (other than Right Certificates representing Rights that have
become void pursuant to Section 11(a)(ii) hereof or that have been exchanged
pursuant to Section 14 hereof) may be (i) transferred or (ii) split up, combined
or exchanged for another Right Certificate or Right Certificates, entitling the
registered holder to



                                       8
<PAGE>   12

purchase a like number of shares of Preferred Stock or other securities as the
Right Certificate or Right Certificates surrendered then entitled such holder to
purchase. Any registered holder desiring to transfer any Right Certificate shall
surrender the Right Certificate at the office of the Rights Agent designated for
such purposes with the form of assignment on the reverse side thereof duly
endorsed (or enclose with such Right Certificate a written instrument of
transfer in form satisfactory to the Company and the Rights Agent), duly
executed by the registered holder thereof or his attorney duly authorized in
writing, and with such signature guaranteed by a member of a securities approved
medallion program. Any registered holder desiring to split up, combine or
exchange any Right Certificate shall make such request in writing delivered to
the Rights Agent, and shall surrender the Right Certificate or Right
Certificates to be split up, combined or exchanged at the principal office of
the Rights Agent. Thereupon the Rights Agent shall, subject to Sections 4(b),
7(e), 11 and 14 hereof, countersign (by manual or facsimile signature) and
deliver to the person entitled thereto a Right Certificate or Right
Certificates, as the case may be, as so requested. The Company may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer, split up, combination or exchange of
Right Certificates.

                (b) Subject to the provisions of Section 11(a)(ii) hereof, upon
receipt by the Company and the Rights Agent of evidence reasonably satisfactory
to them of the loss, theft, destruction or mutilation of a Right Certificate,
and, in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to them, and, if requested by the Company, reimbursement to the
Company of all reasonable expenses incidental thereto, and upon surrender to the
Rights Agent and cancellation of the Right Certificate if mutilated, the Company
will execute and deliver a new Right Certificate of like tenor to the Rights
Agent for delivery to the registered owner in lieu of the Right Certificate so
lost, stolen, destroyed or mutilated.

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

                (a) Subject to Section 11(a)(ii) hereof, the Rights shall become
exercisable, and may be exercised to purchase Preferred Stock, except as
otherwise provided herein, in whole or in part at any time after the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase on the reverse side thereof duly executed (with such
signature duly guaranteed), to the Rights Agent at Continental Stock Transfer &
Trust Company, 2 Broadway, New York, New York 10004, together with payment of
the Purchase Price with respect to each Right exercised, subject to adjustment
as hereinafter provided, at or prior to the Close of Business on the earlier of
(i) November 7, 2010 (the "Final Expiration Date"), (ii) the time at which the
Rights are redeemed as provided in Section 23 hereof (such date being herein
referred to as the "Redemption Date") or (iii) the time at which all such Rights
are exchanged as provided in Section 24 hereof (the earliest of (i), (ii) and
(iii) being herein referred to as the "Expiration Date").

                (b) The Purchase Price and the number of shares of Preferred
Stock or other securities or consideration to be acquired upon exercise of a
Right shall be subject to adjustment from time to time as provided in Sections
11 and 13 hereof. The Purchase Price shall be payable in lawful money of the
United States of America, in accordance with Section 7(c) hereof.



                                       9
<PAGE>   13

                (c) Except as provided in Section 11(a)(ii) hereof, upon receipt
of a Right Certificate with the form of election to purchase duly executed,
accompanied by payment of the Purchase Price (as such amount may be reduced
pursuant to Section 11(a)(iii) hereof) or so much thereof as is necessary for
the shares to be purchased and an amount equal to any applicable transfer tax,
by cash, certified check or official bank check payable to the order of the
Company or the Rights Agent, the Rights Agent shall, subject to Section 20(j),
thereupon promptly (i) requisition from any transfer agent of the Preferred
Stock (or make available if the Rights Agent is the transfer agent) certificates
for the number of shares of Preferred Stock so elected to be purchased and the
Company will comply and hereby authorizes and directs such transfer agent to
comply with all such requests, (ii) requisition from the Company the amount of
cash to be paid in lieu of issuance of fractional shares in accordance with
Section 14(b) hereof, and (iii) promptly after receipt of such Preferred Stock
certificates 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, when appropriate, after receipt promptly
deliver such cash to or upon the order of the registered holder of such Right
Certificate. In the event of a purchase of securities, other than Preferred
Stock, pursuant to Section 11(a) or Section 13 hereof, the Rights Agent shall
promptly take the appropriate actions corresponding to the foregoing clauses (i)
through (iii). In the event that the Company is obligated to issue other
securities of the Company, pay cash and/or distribute other property pursuant to
Section 11(a) hereof, the Company will make all arrangements necessary so that
such other securities, cash and/or other property are available for distribution
by the Rights Agent, if and when appropriate.

                (d) Except as otherwise provided herein, 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 Section 14 hereof.

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

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



                                       10
<PAGE>   14

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

        9. Reservation and Availability of Shares of Preferred Stock.

                (a) The Company covenants and agrees that at all times it will
cause to be reserved and kept available, out of and to the extent of its
authorized and unissued shares of Preferred Stock not reserved for another
purpose (and, following the occurrence of a Triggering Event, other securities)
or held in its treasury, the number of shares of Preferred Stock (and, following
the occurrence of a Triggering Event, other securities) that, as provided in
this Agreement, including Section 11(a)(iii) hereof, will be sufficient to
permit the exercise in full of all outstanding Rights, provided, however, that
the Company shall not be required to reserve and keep available shares of
Preferred Stock or other securities sufficient to permit the exercise in full of
all outstanding Rights pursuant to the adjustments set forth in Section
11(a)(ii), Section 11(a)(iii) or Section 13 hereof unless, and only to the
extent that, the Rights become exercisable pursuant to such adjustments.

                (b) The Company shall (i) use its best efforts to cause, from
and after such time as the Rights become exercisable, the Rights and all shares
of Preferred Stock (and following the occurrence of a Triggering Event, other
securities) issued or reserved for issuance upon exercise thereof to be reported
by the National Association of Securities Dealers, Inc. Automated Quotations
System ("NASDAQ"), or such other system then in use, and if the Preferred Stock
shall become listed on any national securities exchange, to cause, from and
after such time as the Rights become exercisable, the Rights and all shares of
Preferred Stock (and, following the occurrence of a Triggering Event, other
securities) issued or reserved for issuance upon exercise thereof to be listed
on such exchange upon official notice of issuance upon such exercise and (ii) if
then necessary, to permit the offer and issuance of such shares of Preferred
Stock (and, following the occurrence of a Triggering Event, other securities),
register and qualify such share of Preferred Stock (and, following the
occurrence of a Triggering Event, other securities) under the Securities Act and
any applicable state securities or "blue sky" laws (to the extent exemptions
therefrom are not available), cause such registration statement and
qualifications to become effective as soon as possible after such filing and
keep such registration and qualifications effective until the Expiration Date of
the Rights. The Company may temporarily suspend, for a period of time not to
exceed ninety (90) days, the exercisability of the Rights in order to prepare
and file a registration statement under the Securities Act and permit it to
become effective. Upon any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement at such time as the suspension is no
longer in effect. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction unless the
requisite qualification in such jurisdiction shall have been obtained and until
a registration statement under the Securities Act (if required) shall have been
declared effective.

                (c) The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all shares of Preferred Stock (and
following the occurrence of a Triggering Event, other securities) delivered upon
exercise of Rights shall, at the time of delivery



                                       11
<PAGE>   15

of the certificates for such shares (subject to payment of the Purchase Price in
respect thereof), be duly and validly authorized and issued and fully paid and
nonassessable shares in accordance with applicable law.

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

        10. Preferred Stock Record Date. Each Person in whose name any
certificate for shares of Preferred Stock (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 shares of Preferred Stock (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. Prior to the exercise of the Rights evidenced thereby,
the holder of a Right Certificate, as such, shall not be entitled to any rights
of a stockholder of the Company with respect to the shares for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

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

                (a) (i) In the event the Company shall at any time after the
date of this Rights Agreement (A) declare or pay any dividend on Preferred Stock
payable in shares of Preferred Stock, (B) subdivide or split the outstanding
shares of Preferred Stock into a greater number of shares, (C) combine or
consolidate the outstanding shares of Preferred Stock into a smaller number of
shares or effect a reverse split of the outstanding shares of Preferred Stock,
or (D) issue any shares of its capital stock in a reclassification of the
Preferred Stock (including any such reclassification in connection with a
consolidation or merger in which the Company is the continuing or surviving
corporation), except as otherwise provided in this Section 11(a), the Purchase
Price in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination or reclassification, and the
number and kind of shares of Preferred Stock or capital stock, as the case may
be, issuable on such date, shall be proportionately adjusted so that the holder
of any Right exercised after such time shall be entitled to receive,



                                       12
<PAGE>   16

upon payment of the Purchase Price then in effect, the aggregate number and kind
of shares of capital stock or other securities which, if such Right had been
exercised immediately prior to such date, the holder thereof would have owned
upon such exercise and been entitled to receive by virtue of such dividend,
subdivision, combination or reclassification. If an event occurs which would
require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii)
hereof, the adjustment provided for in this Section 11(a)(i) shall be in
addition to, and shall be made prior to, any adjustment required pursuant to
Section 11(a)(ii).

                        (ii) Subject to Section 24, in the event

                                (A) any Acquiring Person or any Associate or
Affiliate of any Acquiring Person, at any time after the date of this Agreement,
directly or indirectly, (1) shall consolidate with or merge with and into the
Company or any of its Subsidiaries or otherwise combine with the Company or any
of its Subsidiaries and the Company or such Subsidiary shall be the continuing
or surviving corporation of such consolidation, merger or combination and the
Common Stock of the Company shall remain outstanding and no shares thereof shall
be changed into or exchanged for stock or other securities of the Company or of
any other Person or cash or any other property, or (2) shall, in one or more
transactions, other than in connection with the exercise of a Right or Rights
and other than in connection with the exercise or conversion of securities
exercisable for or convertible into securities of the Company or of any
Subsidiary of the Company, transfer any assets or property to the Company or any
of its Subsidiaries in exchange (in whole or in part) for any shares of any
class of capital stock of the Company or any of its Subsidiaries or any
securities exercisable for or convertible into shares of any class of capital
stock of the Company or any of its Subsidiaries, or otherwise obtain from the
Company or any of its Subsidiaries, with or without consideration, any
additional shares of any class of capital stock of the Company or any of its
Subsidiaries or any securities exercisable for or convertible into shares of any
class of capital stock of the Company or any of its Subsidiaries (other than as
part of a pro rata offer or distribution by the Company or such Subsidiary to
all holders of such shares), or (3) shall sell, purchase, lease, exchange,
mortgage, pledge, transfer or otherwise acquire (other than as a pro rata
dividend) or dispose, to, from or with, as the case may be, in one transaction
or a series of transactions, the Company or any of its Subsidiaries, assets
(including securities) on terms and conditions less favorable to the Company or
such Subsidiary than the Company or such Subsidiary would be able to obtain in
arm's-length negotiation with an unaffiliated third party, or (4) shall receive
any compensation from the Company or any of its Subsidiaries for services other
than compensation for employment as a regular or part-time employee, or fees for
serving as a director, at rates in accordance with the Company's (or its
Subsidiary's) past practices, or (5) shall receive the benefit, directly or
indirectly (except proportionately as a stockholder), of any loans, advances,
guarantees, pledges or other financial assistance or any tax credits or tax
advantage provided by the Company or any of its Subsidiaries, or (6) shall
engage in any transaction with the Company (or any of its Subsidiaries)
involving the sale, license, transfer or grant of any right in, or disclosure
of, any patents, copyrights, trade secrets, trademarks, know-how or any other
intellectual or industrial property rights recognized under any country's
intellectual property laws which the Company (including its Subsidiaries) owns
or has the right to use on terms and conditions not approved by the Board; or



                                       13
<PAGE>   17

                                (B) any Person, alone or together with its
Affiliates and Associates, shall become an Acquiring Person; or

                                (C) during such time as there is an Acquiring
Person, there shall be any reclassification of securities (including any reverse
stock split), or any recapitalization of the Company, or any merger or
consolidation of the Company with any of its Subsidiaries or any other
transaction or series of transactions involving the Company or any of its
Subsidiaries (whether or not with or into or otherwise involving an Acquiring
Person or any Affiliate or Associate of such Acquiring Person) which has the
effect, directly or indirectly, of increasing by more than 1% the proportionate
share of the outstanding shares of any class of equity securities of the Company
or any of its Subsidiaries, or securities exercisable for or convertible into
equity securities of the Company or any of its Subsidiaries, which is directly
or indirectly beneficially owned by any Acquiring Person or any Affiliate or
Associate of any Acquiring Person (any of (A), (B) or (C) being referred to
herein as a "Flip-In Event"),

                        then upon the first occurrence of such Flip-In Event (A)
the Purchase Price shall be adjusted to be the Purchase Price in effect
immediately prior to the Flip-In Event multiplied by the number of one
one-thousandths of a share of Preferred Stock for which a Right was exercisable
immediately prior to such Flip-In Event, whether or not such Right was then
exercisable, and (B) each holder of a Right, except as otherwise provided in
this Section 11(a)(ii) and Section 11(a)(iii) hereof, shall thereafter have the
right to receive, upon exercise thereof at a price equal to the Purchase Price
(as so adjusted), in accordance with the terms of this Agreement and in lieu of
shares of Preferred Stock, such number of shares of Common Stock as shall equal
the result obtained by dividing the Purchase Price (as so adjusted) by 50% of
the Current Market Price per share of the Common Stock (determined pursuant to
Section 11(d) hereof) on the date of such Flip-In Event; provided, however, that
the Purchase Price (as so adjusted) and the number of shares of Common Stock so
receivable upon the exercise of a Right shall, following the Flip-In Event, be
subject to further adjustment as appropriate in accordance with Section 11(f)
hereof. Notwithstanding anything in this Agreement to the contrary, however,
from and after the Flip-In Event, any Rights that are beneficially owned by (x)
any Acquiring Person (or any Affiliate or Associate of any Acquiring Person),
(y) a transferee of any Acquiring Person (or any such Affiliate or Associate)
who becomes a transferee after the Flip-In Event or (z) a transferee of any
Acquiring Person (or any such Affiliate or Associate) who became a transferee
prior to or concurrently with the Flip-In Event pursuant to either (I) a
transfer from the Acquiring Person to holders of its equity securities or to any
Person with whom it has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (II) a transfer which the Board of Directors
has determined is part of a plan, arrangement or understanding which has the
purpose or effect of avoiding the provisions of this paragraph, and subsequent
transferees of such Persons, shall be void without any further action and any
holder of such Rights shall thereafter have no rights whatsoever with respect to
such Rights under any provision of this Agreement. The Company shall use all
reasonable efforts to ensure that the provisions of this Section 11(a)(ii) are
complied with, but shall have no liability to any holder of Right Certificates
or other Person as a result of its failure to make any determinations with
respect to an Acquiring Person or its Affiliates, Associates or transferees
hereunder. From and after the Flip-In Event, no Right Certificate shall be
issued pursuant to Section 3 or Section 6 hereof that represents Rights that are
or have become void pursuant to the provisions of this


                                       14
<PAGE>   18
paragraph, and any Right Certificate delivered to the Rights Agent that
represents Rights that are or have become void pursuant to the provisions of
this paragraph shall be canceled.

                        (iii) The Company may at its option substitute for a
share of Common Stock issuable upon the exercise of Rights in accordance with
the foregoing subparagraph (ii) such number or fractions of shares of Preferred
Stock having an aggregate current market value equal to the Current Market Price
of a share of Common Stock. In the event that there shall not be sufficient
shares of Common Stock issued but not outstanding or authorized but unissued to
permit the exercise in full of the Rights in accordance with the foregoing
subparagraph (ii), the Board of Directors shall, to the extent permitted by
applicable law and any material agreements then in effect to which the Company
is a party (A) determine the excess (such excess, the "Spread") of (1) the value
of the shares of Common Stock issuable upon the exercise of a Right in
accordance with the foregoing subparagraph (ii) (the "Current Value") over (2)
the Purchase Price (as adjusted in accordance with the foregoing subparagraph
(ii)), and (B) with respect to each Right (other than Rights which have become
void pursuant to the foregoing subparagraph (ii)), make adequate provision to
substitute for the shares of Common Stock issuable in accordance with the
foregoing paragraph (ii) upon exercise of the Right and payment of the Purchase
Price (as adjusted in accordance therewith), (1) cash, (2) a reduction in such
Purchase Price, (3) shares of Preferred Stock or other equity securities of the
Company (including, without limitation, shares or fractions of shares of
preferred stock which, by virtue of having dividend, voting and liquidation
rights substantially comparable to those of the shares of Common Stock, are
deemed in good faith by the Board of Directors to have substantially the same
value as the shares of Common Stock (such shares of Preferred Stock and shares
or fractions of shares of preferred stock are hereinafter referred to as "Common
Stock Equivalents," (4) debt securities of the Company, (5) other assets, or (6)
any combination of the foregoing, having a value which, when added to the value
of the shares of Common Stock actually issued upon exercise of such Right, shall
have an aggregate value equal to the Current Value (less the amount of any
reduction in such Purchase Price), where such aggregate value has been
determined by the Board of Directors upon the advice of a nationally recognized
investment banking firm selected in good faith by the Board of Directors;
provided, however, that if the Company shall not make adequate provision to
deliver value pursuant to clause (B) above within thirty (30) days following the
Flip-In Event (the "Flip-in Trigger Date"), then the Company shall be obligated
to deliver, to the extent permitted by applicable law and any material
agreements then in effect to which the Company is a party, upon the surrender
for exercise of a Right and without requiring payment of such Purchase Price,
shares of Common Stock (to the extent available), and then, if necessary, such
number or fractions of shares of Preferred Stock (to the extent available) and
then, if necessary, cash, which shares and/or cash have an aggregate value equal
to the Spread. If the Board of Directors of the Company shall determine in good
faith that it is likely that sufficient additional shares of Common Stock and/or
Common Stock Equivalents could be authorized for issuance upon exercise in full
of the Rights, the thirty (30) day period set forth above may be extended to the
extent necessary, but not more than ninety (90) days after the Flip-In Trigger
Date, in order that the Company may seek stockholder approval for the
authorization of such additional shares or Common Stock Equivalents (such thirty
(30) day period, as it may be extended, is herein called the "Substitution
Period"). To the extent that the Company determines that some action need be
taken pursuant to the second and/or third sentence



                                       15
<PAGE>   19

of this Section 11(a)(iii), the Company (x) shall provide, subject to the last
sentence of Section 11(a)(ii) hereof, that such action shall apply uniformly to
all outstanding Rights, and (y) may suspend the exercisability of the Rights
until the expiration of the Substitution Period in order to seek any
authorization of additional shares and/or to decide the appropriate form of
distribution to be made pursuant to the first sentence of Section 11(a)(iii) and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement stating that the exercisability of the Rights
has been temporarily suspended, as well as a public announcement at such time as
the suspension is no longer in effect. For purposes of this Section 11(a)(iii),
the value of the Common Stock shall be the Current Market Price per share of the
Common Stock on the Flip-In Trigger Date and the per share or per unit value of
any Common Stock Equivalent shall be deemed to equal the Current Market Price
per share of the Common Stock on such date. The Board of Directors may, but
shall not be required to, establish procedures to allocate the right to receive
Common Stock upon the exercise of the Rights among holders of Rights pursuant to
this Section 11(a)(iii).

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

                (c) In case the Company shall fix a record date for a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash, assets (other than a
dividend payable in Preferred Stock, but including any dividend payable in



                                       16
<PAGE>   20

stock other than Preferred Stock) or subscription rights or warrants (excluding
those referred to in Section 11(b) hereof), the Purchase Price to be in effect
after such record date shall be determined by multiplying the Purchase Price in
effect immediately prior to such record date by a fraction, the numerator of
which shall be the Current Market Price per share of Preferred Stock on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the cash, assets or
evidences of indebtedness to be distributed or of such subscription rights or
warrants applicable to a share of Preferred Stock and the denominator of which
shall be such Current Market Price per share of Preferred Stock. Such
adjustments shall be made successively whenever such a record date is fixed, and
in the event that such distribution is not so made, the Purchase Price shall be
adjusted to be the Purchase Price which would have been in effect if such record
date had not been fixed.

                (d) (i) For the purpose of any computation hereunder, other than
computations made pursuant to Section 11(a)(iii) hereof, the "Current Market
Price" per share of Common Stock on any date shall be deemed to be the average
of the daily closing prices per share of the Common Stock for the thirty (30)
consecutive Trading Days (as such term is hereinafter defined) immediately prior
to such date, and for purpose of computations made pursuant to Section
11(a)(iii) hereof, the "Current Market Price" per share of the Common Stock on
any date shall be deemed to be the average of the daily closing prices per share
of the Common Stock for the ten (10) consecutive Trading Days immediately
following such date; provided, however, that in the event that the Current
Market Price per share of the Common Stock is determined during a period
following the announcement by the issuer of the Common Stock of (i) any dividend
or distribution on the Common Stock (other than a regular quarterly cash
dividend and other than the Rights), (ii) any subdivision, combination or
reclassification of the Common Stock, and prior to the expiration of the
requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth
above, after the ex-dividend date for such dividend or distribution, or the
record date for such subdivision, combination or reclassification occurs, then,
and in each such case, the Current Market Price shall be properly adjusted to
take into account ex-dividend trading. The closing price for each day shall be
the last sale price, regular way, or, in case no such sale takes place on such
day, the average of the closing bid and asked prices, regular way, in either
case as reported in the principal consolidated transaction reporting system with
respect to securities listed or admitted to trading on the New York Stock
Exchange or, if the shares of Common Stock are not listed or admitted to trading
on the New York Stock Exchange, as reported in the principal consolidated
transaction reporting system with respect to securities listed on the principal
national securities exchange on which the shares of Common Stock are listed or
admitted to trading or, if the shares of Common Stock are not listed or admitted
to trading on any national securities exchange, the last quoted sale 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 shares of Common Stock are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Common Stock selected by the
Board of Directors of the Company. If on any such date no market maker is making
a market in the Common Stock, the fair value of such shares on such date as
determined in good faith by the Board of Directors of the Company shall be used
and shall be binding on the Rights Agent. The



                                       17
<PAGE>   21

term "Trading Day" shall mean a day on which the principal national securities
exchange on which the shares of Common Stock are listed or admitted to trading
is open for the transaction of business or, if the shares of Common Stock are
not listed or admitted to trading on any national securities exchange, a
Business Day. If the Common Stock is not publicly held or not so listed or
traded, "Current Market Price" per share shall mean the fair value per share as
determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

                        (ii) For the purpose of any computation hereunder, the
"Current Market Price" per share (or one one-thousandth of a share) of Preferred
Stock shall be determined in the same manner as set forth above for the Common
Stock in clause (i) of this Section 11(d) (other than the last sentence
thereof). If the Current Market Price per share (or one one-thousandth of a
share) of Preferred Stock cannot be determined in the manner provided above or
if the Preferred Stock is not publicly held or listed or traded in a manner
described in clause (i) of this Section 11(d), the "Current Market Price" per
share of Preferred Stock shall be conclusively deemed to be an amount equal to
1,000 (as such number may be appropriately adjusted for such events as stock
splits, stock dividends and recapitalizations with respect to the Common Stock
occurring after the date of this Agreement) multiplied by the Current Market
Price per share of the Common Stock, and the "Current Market Price" per one
one-thousandth of a share of Preferred Stock shall, be equal to the Current
Market Price per share of the Common Stock (as appropriately adjusted). If
neither the Common Stock nor the Preferred Stock is publicly held or so listed
or traded, "Current Market Price" per shall mean the fair value per share as
determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

                (e) Anything herein to the contrary notwithstanding, no
adjustment in the Purchase Price shall be required unless such adjustment would
require an increase or decrease of at least one percent in the Purchase Price;
provided, however, that any adjustments which by reason of this Section 11(e)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section 11 shall be made
to the nearest cent or to the nearest ten-thousandth of a share of Common Stock
or other share or one-hundred-thousandth of a share of Preferred Stock, as the
case may be. Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which mandates such
adjustment, or (ii) the Expiration Date.

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



                                       18
<PAGE>   22

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

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

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

                (j) Irrespective of any adjustment or change in the Purchase
Price or the number of shares of Preferred Stock issuable upon the exercise of
the Rights, the Right



                                       19
<PAGE>   23

Certificates theretofore and thereafter issued may continue to express the
Purchase Price per share and the number of shares which were expressed in the
initial Right Certificate issued hereunder.

                (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the shares of
Common Stock, Preferred Stock or other capital stock issuable upon exercise of
the Rights, the Company shall take any corporate action, including using its
best efforts to obtain any required stockholder approvals, which may, in the
opinion of its counsel, be necessary in order that the Company may validly and
legally issue fully paid and nonassessable shares of Common Stock, Preferred
Stock or other capital stock at such adjusted Purchase Price. If upon any
exercise of the Rights, a holder is to receive a combination of Common Stock and
Common Stock Equivalents, a portion of the consideration paid upon such
exercise, equal to at least the then par value of a share of Common Stock of the
Company, shall be allocated as the payment for each share of Common Stock of the
Company so received.

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

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

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



                                       20
<PAGE>   24

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

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

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

        12. Certification of Adjustments. Whenever an adjustment is made as
provided in Sections 11 and 13 hereof, the Company shall (a) promptly prepare a
certificate signed by its Chief Executive Officer, its President or any Vice
President and by the Treasurer or any Assistant Treasurer or the Secretary or
any Assistant Secretary of the Company setting forth such adjustment and a brief
statement of the facts giving rise to such adjustment, (b) promptly file with
the Rights Agent and with each transfer agent for the Preferred Stock and the
Common Stock a copy of such certificate and (c) mail a brief summary thereof to
each holder of a Right Certificate (or, if prior to the Distribution Date, to
each holder of a certificate representing shares of Common Stock) in accordance
with Section 26 hereof. Notwithstanding the foregoing sentence, the failure of
the Company to give such notice shall not affect the validity of or the force or
effect of or the requirement for such adjustment. The Rights Agent shall be
fully protected in relying on any certificate prepared by the Company pursuant
to Sections 11 and 13 and on any adjustment therein contained and shall not be
responsible or obligated for calculating any adjustment and shall not be deemed
to have knowledge of any such adjustment unless and until it shall have received
such certificate. Any adjustment to be made pursuant to Sections 11 and 13 of
this Rights Agreement shall be effective as of the date of the event giving rise
to such adjustment.



                                       21
<PAGE>   25

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

                (a) In the event that following the first occurrence of a
Flip-In Event, directly or indirectly, (x) the Company shall consolidate with,
or merge with and into, any other Person or Persons and the Company shall not be
the surviving or continuing corporation of such consolidation or merger, or (y)
any Person or Persons shall consolidate with, or merge with and into, the
Company, and the Company shall be the continuing or surviving corporation of
such consolidation or merger and, in connection with such consolidation or
merger, all or part of the outstanding shares of Common Stock shall be changed
into or exchanged for stock or other securities of any other Person or of the
Company or cash or any other property other than, in the case of the
transactions described in subparagraphs (x) or (y), a merger or consolidation
which would result in all of the Voting Power represented by the securities of
the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into securities of the
surviving entity) all of the Voting Power represented by the securities of the
Company 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 transactions), or (z) the Company or one or more of its Subsidiaries
shall sell, mortgage or otherwise transfer to any other Person or any Affiliate
or Associate of such Person, in one transaction, or a series of related
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole), then, on
the first occurrence of any such event (a "Flip-Over Event"), proper provision
shall be made so that (i) each holder of a Right (other than Rights which have
become void pursuant to Section 11(a)(ii) hereof) shall thereafter have the
right to receive, upon the exercise thereof at the Purchase Price (as
theretofore adjusted in accordance with Section 11(a)(ii) hereof), in accordance
with the terms of this Agreement and in lieu of shares of Preferred Stock or
Common Stock of the Company, such number of validly authorized and issued, fully
paid, non-assessable and freely tradeable shares of Common Stock of the
Principal Party (as such term is hereinafter defined), not subject to any liens,
encumbrances, rights of first refusal or other adverse claims, as shall equal
the result obtained by dividing the Purchase Price (as theretofore adjusted in
accordance with Section 11(a)(ii) hereof) by 50% of the Current Market Price per
share of the Common Stock of such Principal Party (determined pursuant to
Section 11(d) hereof) on the date of consummation of such consolidation, merger,
sale or transfer; provided, however, that the Purchase Price (as theretofore
adjusted in accordance with Section 11(a)(ii) hereof) and the number of shares
of Common Stock of such Principal Party so receivable upon exercise of a Right
shall be subject to further adjustment as appropriate in accordance with Section
11(f) hereof to reflect any events occurring in respect of the Common Stock of
such Principal Party after the occurrence of such consolidation, merger, sale or
transfer; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such Flip-Over Event, all the obligations and duties of the
Company pursuant to this Rights Agreement; (iii) the term "Company" for all
purposes of this Rights Agreement shall thereafter be deemed to refer to such
Principal Party, it being specifically intended that the provisions of Section
11 hereof shall only apply to such Principal Party following the first
occurrence of a Flip-Over Event; and (iv) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
shares of its Common Stock in accordance with Section 9 hereof) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof



                                       22
<PAGE>   26

shall thereafter be applicable, as nearly as reasonably may be, in relation to
its shares of Common Stock thereafter deliverable upon the exercise of the
Rights; provided, however, that, upon the subsequent occurrence of any merger,
consolidation, sale of all or substantially all assets, recapitalization,
reclassification of shares, reorganization or other extraordinary transaction in
respect of such Principal Party, each holder of a Right shall thereupon be
entitled to receive, upon exercise of a Right, such cash, shares, rights,
warrants and other property which such holder would have been entitled to
receive had he, at the time of such transaction, owned the shares of Common
Stock of the Principal Party purchasable upon the exercise of a Right, and such
Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property.

                (b) "Principal Party" shall mean

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

                        (ii) in the case of any transaction described in (z) of
the first sentence in Section 13(a) hereof, the Person that is the party
receiving the greatest portion of the assets or earning power transferred
pursuant to such transaction or transactions, or, if each Person that is a party
to such transaction or transactions receives the same portion of the assets or
earning power so transferred or if the Person receiving the greatest portion of
the assets or earning power cannot be determined, whichever of such Persons as
is the issuer of Common Stock having the greatest aggregate market value of
shares outstanding;

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



                                       23
<PAGE>   27

venturers, and the Principal Party in each such case shall bear the obligations
set forth in this Section 13 in the same ratio as its interest in such Person
bears to the total of such interests.

                (c) The Company shall not consummate any consolidation, merger,
sale or transfer referred to in Section 13(a) unless the Principal Party shall
have a sufficient number of authorized shares of its Common Stock that have not
been issued or reserved for issuance to permit the exercise in full of the
Rights in accordance with this Section 13 and unless prior thereto the Company
and the Principal Party involved therein shall have executed and delivered to
the Rights Agent an agreement confirming that the requirements of Sections 13(a)
and (b) hereof shall promptly be performed in accordance with their terms and
that such consolidation, merger, sale or transfer of assets shall not result in
a default by the Principal Party under this Rights Agreement as the same shall
have been assumed by the Principal Party pursuant to Sections 13(a) and (b)
hereof and further providing that, as soon as practicable after executing such
agreement pursuant to this Section 13, the Principal Party at its own expense
shall:

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

                        (ii) use its best efforts, if the Common Stock of the
Principal Party shall become listed on a national securities exchange, to list
(or continue the listing of) the Rights and the securities purchasable upon
exercise of the Rights on such securities exchange and, if the Common Stock of
the Principal Party shall not be listed on a national securities exchange, to
cause the Rights and the securities purchased upon exercise of the Rights to be
reported by NASDAQ or such other system then in use;

                        (iii) 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 (or any successor form) under the
Exchange Act; and

                        (iv) obtain waivers of any rights of first refusal or
preemptive rights in respect of the shares of Common Stock of the Principal
Party subject to purchase upon exercise of outstanding Rights.

In the event that any of the transactions described in Section 13(a) hereof
shall occur at any time after the occurrence of a transaction described in
Section 11(a)(ii) hereof, the Rights which have not theretofore been exercised
shall thereafter be exercisable in the manner described in Section 13(a).

                (d) Furthermore, in case the Principal Party which is to be a
party to a transaction referred to in this Section 13 has a provision in any of
its authorized securities or in its Certificate of Incorporation or Bylaws or
other instrument governing its corporate affairs,



                                       24
<PAGE>   28

which provision would have the effect of (i) causing such Principal Party to
issue, in connection with, or as a consequence of, the consummation of a
transaction referred to in this Section 13, shares of Common Stock of such
Principal Party at less than the then Current Market Price per share (determined
pursuant to Section 11(d) hereof) or securities exercisable for, or convertible
into, Common Stock of such Principal Party at less than such then current market
price (other than to holders of Rights pursuant to this Section 13) or (ii)
providing for any special payment, tax or similar provisions in connection with
the issuance of the Common Stock of such Principal Party pursuant to the
provisions of Section 13, then, in such event, the Company hereby agrees with
each holder of Rights that it shall not consummate any such transaction unless
prior thereto the Company and such Principal Party shall have executed and
delivered to the Rights Agent a supplemental agreement providing that the
provision in question of such Principal Party shall have been canceled, waived
or amended, or that the authorized securities shall be redeemed, so that the
applicable provision will have no effect in connection with, or as a consequence
of, the consummation of the proposed transaction.

        14. Fractional Rights and Fractional Shares.

                (a) The Company shall not be required to issue fractions of
Rights or to distribute Right Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the holders of record 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 then
current market value of a whole Right. For the purposes of this Section 14(a),
the then current market value of a Right shall be determined in the same manner
as the Current Market Price of a share of Common Stock shall be determined
pursuant to Section 11(d) hereof.

                (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral multiples of
one one-thousandth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates which evidence fractional shares of Preferred Stock
(other fractions which are integral multiples of one one-thousandth of a share
of Preferred Stock). Fractions of shares of Preferred Stock in integral
multiples of one one-thousandth of a share of Preferred Stock may, at the
election of the Company, be evidenced by depository receipts, pursuant to an
appropriate agreement between the Company and a depository selected by it,
provided that such agreement shall provide that the holders of such depository
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the shares of Preferred Stock represented by
such depository receipts. In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-thousandth of a share of Preferred Stock,
the Company 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 one one-thousandth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market value of
one one-thousandth of a share of Preferred Stock shall be the Current Market
Price of a share of Common Stock (as determined pursuant to Section 11(d)(ii)
hereof) for the Trading Day immediately prior to the date of such exercise.

                (c) Following the occurrence of a Flip-In Event, the Company
shall not be required to issue fractions of shares or units of Common Stock or
Common Stock Equivalents or



                                       25
<PAGE>   29

other securities upon exercise of the Rights or to distribute certificates which
evidence fractional shares of such Common Stock or Common Stock Equivalents or
other securities. In lieu of fractional shares or units of such Common Stock or
Common Stock Equivalents or other securities, the Company 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 Stock or Common Stock Equivalent
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
Common Stock Equivalent is not traded, each such Common Stock Equivalent shall
have the value of one one-thousandth of a share of Preferred Stock.

                (d) The holder of a Right by the acceptance of a Right expressly
waives his right to receive any fractional Right or any fractional shares upon
exercise of a Right.

        15. Rights of Action. All rights of action in respect of this Agreement,
other than any rights of action vested in the Rights Agent pursuant to Sections
18 and 20 below, are vested in the respective holders of record of the Right
Certificates (and, prior to the Distribution Date, the holders of record of the
Common Stock); and any holder of record of any Right Certificate (or, prior to
the Distribution Date, of the Common Stock), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in his own behalf and for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company or any other Person 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, accordingly, that they 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. Holders of Rights shall be entitled to recover the
reasonable costs and expenses, including attorneys' fees, incurred by them in
any action to enforce the provisions of this Agreement.

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

                (a) prior to the Distribution Date, the Rights will not be
evidenced by a Right Certificate and will be transferable only in connection
with the transfer of Common Stock;

                (b) after the Distribution Date, the Right Certificates will be
transferable only on the registry books of the Rights Agent if surrendered at
the office of the Rights Agent designated for such purpose, duly endorsed or
accompanied by a proper instrument of transfer;

                (c) the Company and the Rights Agent may deem and treat the
person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common



                                       26
<PAGE>   30

Stock 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 Stock certificate made by anyone
other than the Company or the Rights Agent or the transfer agent of the Common
Stock) for all purposes whatsoever, and neither the Company nor the Rights Agent
shall be affected by any notice to the contrary; and

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

        17. Right Certificate Holder Not Deemed a Stockholder. No holder of a
Right, as such, shall be entitled to vote, receive dividends in respect of or be
deemed for any purpose to be the holder of Common Stock or any other securities
of the Company which may at any time be issuable upon the exercise of the
Rights, 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 stockholder of the Company or any right to vote in the election
of directors or upon any matter submitted to stockholders at any meeting
thereof, or to give or withhold consent to any corporate action, or to receive
notice of meetings or other actions affecting stockholders (except as provided
in Section 25 hereof), or to receive dividends or subscription rights in respect
of any such stock or securities, or otherwise, until the Right or Rights
evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

        18. Concerning the Rights Agent.

                (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all service rendered by it hereunder and, from time to time, on
demand of the Rights Agent, its reasonable expenses and counsel fees and other
disbursements incurred in the administration and execution of this Rights
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability or expense incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent for any thing done or omitted
to be done by the Rights Agent in connection with the acceptance and
administration of this Rights Agreement, including the cost and expenses of
defending against any claim of liability in the premises. The costs and expenses
of enforcing this right of indemnification shall also be paid by the Company.
The indemnity provided herein shall survive the expiration of the Rights and the
termination of this Rights Agreement. Anything in this agreement to the contrary
notwithstanding, in no event shall the Rights Agent be liable for special,
indirect 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 damage and regardless of the form of action.



                                       27
<PAGE>   31

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

        19. Merger or Consolidation or Changed Name of Rights Agent.

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

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

        20. Duties of Rights Agent. The Rights Agent undertakes the duties and
obligations imposed by this Rights Agreement upon the following terms and
conditions, and no implied duties or obligations shall be read into this
Agreement against the Rights Agent by all of which the Company and the holders
of Right Certificates, by their acceptance thereof, shall be bound:

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



                                       28
<PAGE>   32

                (b) Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person and
the determination of "Current Market Price") be proved or established by the
Company prior to taking or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by certificate signed by the
President or any Vice President and by the Treasurer or any Assistant Treasurer
or the Secretary or any Assistant Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization to the Rights
Agent for any action taken or suffered in good faith by it under the provisions
of this Rights 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 Rights Agreement or in
the Right Certificates (except its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

                (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Rights Agreement or the execution and delivery
hereof (except the due execution hereof by the Rights Agent) or in respect of
the validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Rights Agreement or in any Right
Certificate; nor shall it be responsible for any adjustment required under the
provisions of Sections 11, 13, 23 or 24 hereof or responsible for the manner,
method or amount of any such adjustment or the ascertaining of the existence of
facts that would require any such adjustment (except with respect to the
exercise of Rights evidenced by Right Certificates after receipt of a
Certificate furnished pursuant to Section 12 describing any such adjustment);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Common Stock to
be issued pursuant to this Rights Agreement or any Right Certificate or as to
whether any shares of Common Stock will, when issued, be validly authorized and
issued, fully paid and nonassessable.

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

                (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the Chief Executive Officer, the President or any Vice
President or the Secretary or any Assistant Secretary or the Treasurer or any
Assistant Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer. Any application by the Rights Agent for
written instructions from the Company



                                       29
<PAGE>   33

may, at the option of the Rights Agent, set forth in writing any action proposed
to be taken or omitted by the Rights Agent under this Rights Agreement and the
date on and/or after which such action shall be taken or such omission shall be
effective. Subject to Section 20(c) hereof, 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 Company actually receives such application, unless any such
officer shall have consented in writing to an earlier date) unless, prior to
taking any such action (or the effective date in the case of an omission), the
Rights Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted.

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

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

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

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

                (l) The Rights Agent shall not be required to take notice or be
deemed to have notice of any fact, event or determination (including, without
limitation, and dates or events defined in this Agreement or the designation of
any Person as an Acquiring Person, Affiliate or Associate) under this Agreement
unless and until the Rights Agent shall be notified in writing by the Company of
such fact, event or determination.

        21. Change of Rights Agent. The Rights Agent or any successor Rights
Agent may resign and be discharged from its duties under this Rights Agreement
upon thirty (30) days'



                                       30
<PAGE>   34

notice in writing, or such earlier period as shall be agreed to in writing,
mailed to the Company and to each transfer agent of the Common Stock by
registered or certified mail, and, at the expense of the Company, to the holders
of the Right Certificates by first-class mail. The Company may remove the Rights
Agent or any successor Rights Agent (with or without cause) upon thirty (30)
days' notice in writing, or such earlier period as shall be agreed to in
writing, mailed to the Rights Agent or successor Rights Agent, as the case may
be, and to each transfer agent of the Common Stock by registered or certified
mail, and to the holders of the Right Certificates by first-class mail. If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent.
Notwithstanding the foregoing provisions of this Section 21, in no event shall
the resignation or removal of a Rights Agent be effective until a successor
Rights Agent shall have been appointed and have accepted such appointment. If
the Company shall fail to make such appointment within a period of thirty (30)
days after such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Right Certificate (who shall, with such notice, submit his Right
Certificate for inspection by the Company), then the incumbent Rights Agent or
the holder of record of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be (a)
a corporation organized and doing business under the laws of the United States
or any State thereof, in good standing, which is authorized under such laws to
exercise corporate trust or stock transfer powers and is subject to supervision
or examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least
$50,000,000 or (b) an Affiliate controlled by a corporation described in clause
(a) of this sentence. After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock, and 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.

        22. Issuance of New Right Certificates. Notwithstanding any of the
provisions of this Rights Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Purchase Price per share and the number or kind or class of
shares of stock or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Rights Agreement. In
addition, in connection with the issuance or sale of shares of Common Stock
following the Distribution Date and prior to the redemption or expiration of the
Rights, the Company shall, with respect to shares of Common Stock so issued or
sold pursuant to the exercise of stock options or under any employee plan or
arrangement, or upon the exercise, conversion or exchange of securities
hereinafter



                                       31
<PAGE>   35

issued by the Company, in each case existing prior to the Distribution Date,
issue Right Certificates representing the appropriate number of Rights in
connection with such issuance or sale; provided, however, that (i) no such Right
Certificate shall be issued if, and to the extent that, the Company shall be
advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Right Certificate would be issued, and (ii) no such Right Certificate shall be
issued, if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

        23. Redemption.

                (a) The Board of Directors of the Company may, at its option, at
any time prior to the earlier of (x) the first occurrence of a Flip-In Event or
(y) the Close of Business on the Expiration Date, redeem all but not less than
all the then outstanding Rights at a redemption price of $.001 per Right, as
such amount may be appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof (such redemption
price being hereinafter referred to as the "Redemption Price").

                (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights (or at such later time as the
Board of Directors may establish for the effectiveness of such redemption), and
without any further action and without any notice, the right to exercise the
Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price. The Company shall promptly give public
notice of any such redemption; provided, however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within ten (10) days after such action of the Board of Directors ordering the
redemption of the Rights (or such later time as the Board of Directors may
establish for the effectiveness of such redemption), the Company shall mail a
notice of redemption to all the holders of the then outstanding Rights at their
last addresses as they appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Stock. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of redemption shall state the method by which the payment of the Redemption
Price will be made. The failure to give notice required by this Section 23(b) or
any defect therein shall not affect the legality or validity of the action taken
by the Company.

                (c) In the case of a redemption permitted under Section 23(a),
the Company may, at its option, discharge all of its obligations with respect to
the Rights by (i) issuing a press release announcing the manner of redemption of
the Rights and (ii) mailing payment of the Redemption Price to the registered
holders of the Rights at their last addresses as they appear on the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent of the Common Stock, and upon such action, all
outstanding Right Certificates shall be null and void without any further action
by the Company.

        24. Exchange of Rights for Common Stock.

                (a) The Board of Directors of the Company may, at its option, at
any time after the occurrence of a Flip-In Event, exchange all or part of the
then outstanding and



                                       32
<PAGE>   36

exercisable Rights (which (i) shall not include Rights that have become void
pursuant to the provisions of Section 11(a)(ii) and (ii) shall include, without
limitation, any Rights issued after the Distribution Date in accordance with
Section 22) for shares of Common Stock at an exchange ratio of one share of
Common Stock per Right, appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof (such exchange
ratio being hereinafter referred to as the "Exchange Ratio"). Notwithstanding
the foregoing, the Board of Directors shall not be empowered to effect such
exchange at any time after any Person (other than an Exempt Person), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of shares of Common Stock aggregating 50% or more of the shares of Common Stock
then outstanding. From and after the occurrence of an event specified in Section
13(a) hereof, any Rights that theretofore have not been exchanged pursuant to
this Section 24(a) shall thereafter be exercisable only in accordance with
Section 13 and may not be exchanged pursuant to this Section 24(a).

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

                (c) In any exchange pursuant to this Section 24, the Company, at
its option, may substitute, and, in the event that there shall not be sufficient
shares of Common Stock issued but not outstanding or authorized but unissued to
permit any exchange of Rights as contemplated in accordance with this Section
24, the Company shall substitute to the extent of such insufficiency, for each
share of Common Stock that would otherwise be issuable upon exchange of a Right,
a number of shares of Preferred Stock or fractions thereof (or Equivalent
Preferred Shares, as such term is defined in Section 11(b)) having an aggregate
current per share market price (determined pursuant to Section 11(d) hereof)
equal to the current per share market price of one share of Common Stock
(determined pursuant to Section 11(d) hereof) as of the date of the Flip-In
Event.

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



                                       33
<PAGE>   37

be necessary to authorize additional shares of Common Stock for issuance upon
exchange of the Rights.

                (e) The Company shall not be required to issue fractions of
shares of Common Stock or to distribute certificates which evidence fractional
shares of Common Stock. In lieu of such fractional shares of Common Stock, the
Company shall pay to the registered holders of the Right Certificates with
regard to which such fractional shares of Common Stock would otherwise be
issuable an amount in cash equal to the same fraction of the current market
value of a whole share of Common Stock. For the purposes of this paragraph (d),
the current market value of a whole share of Common Stock shall be the Current
Market Price of a share of Common Stock (as defined in Section 11(d) hereof for
the purposes of computations made other than pursuant to Section 11(a)(iii)) for
the Trading Day immediately prior to the date of exchange pursuant to this
Section 24.

        25. Notice of Proposed Actions.

                (a) In case the Company, after the Distribution Date, shall
propose (i) to effect any of the transactions referred to in Section 11(a)(i) or
to pay any dividend to the holders of record of its Preferred Stock payable in
stock of any class or to make any other distribution to the holders of record of
its Preferred Stock (other than a regular periodic cash dividend), or (ii) to
offer to the holders of record of its Preferred Stock or options, warrants, or
other rights to subscribe for or to purchase shares of Preferred Stock
(including any security convertible into or exchangeable for Preferred Stock) or
shares of stock of any other class or any other securities, options, warrants,
convertible or exchangeable securities or other rights, or (iii) to effect any
reclassification of its Preferred Stock or any recapitalization or
reorganization of the Company, or (iv) to effect any consolidation or merger
with or into, 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 more than 50% of the assets or earning power of the Company and
its Subsidiaries (taken as a whole) to, any other Person or Persons, or (v) to
effect the liquidation, dissolution or winding up of the Company, then, in each
such case, the Company shall give to each holder of record of a Right
Certificate, in accordance with Section 26 hereof, notice of such proposed
action, which shall specify the record date for the purposes of such transaction
referred to in Section 11(a)(i), or such dividend or distribution, or the date
on which such reclassification, recapitalization, reorganization, consolidation,
merger, sale or transfer of assets, liquidation, dissolution or winding up is to
take place and the record date for determining participation therein by the
holders of record of Preferred Stock, if any such date is to be fixed, and such
notice shall be so given in the case of any action covered by clause (i) or (ii)
above at least 10 days prior to the record date for determining holders of
record of the Preferred Stock for purposes of such action, and in the case of
any such other action, at least 10 days prior to the date of the taking of such
proposed action or the date of participation therein by the holders of record of
Preferred Stock, whichever shall be the earlier.

                (b) In case any of the transactions referred to in Section
11(a)(ii) or Section 13 of this Rights Agreement are proposed, then, in any such
case, the Company shall give to each holder of Rights, in accordance with
Section 26 hereof, notice of the proposal of such transaction at least 10 days
prior to consummating such transaction, which notice shall specify the proposed



                                       34
<PAGE>   38

event and the consequences of the event to holders of Rights under Section
11(a)(ii) or Section 13 hereof, as the case may be, and, upon consummating such
transaction, shall similarly give notice thereof to each holder of Rights.

                (c) The failure to give notice required by this Section 25 or
any defect therein shall not affect the legality or validity of the action taken
by the Company or the vote upon any such action.

        26. Notices. Notices or demands authorized by this Rights Agreement to
be given or made by the Rights Agent or by the holder of record of any Right
Certificate or Right to or on behalf of the Company shall be sufficiently given

the Company or the Rights Agent to the holder of record of any Right Certificate
or Right 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 it
appears upon the registry books of the Rights Agent or, prior to the
Distribution Date, on the registry books of the Transfer Agent.

        27. Supplements and Amendments. Except as provided in the penultimate
sentence of this Section 27, for so long as the Rights are then redeemable, the
Company may in its sole and absolute discretion, and the Rights Agent shall if
the Company so directs, supplement or amend any provision of this Agreement in
any respect without the approval of any holders of the Rights. At any time when
the Rights are no longer redeemable, except as provided in the penultimate
sentence of this Section 27, the Company may, and the Rights Agent shall, if the
Company so directs, supplement or amend this Agreement without the approval of
any holders of Rights Certificates in order to (i) cure any ambiguity, (ii)
correct or supplement any provision contained herein which may be defective or
inconsistent with any other provisions herein, (iii) shorten or lengthen any

such



                                       35
<PAGE>   39

supplement or amendment shall adversely affect the interests of the holders
of Rights as such (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person), and no such amendment may cause the Rights again to
become redeemable or cause the Agreement again to become amendable other than in
accordance with this sentence. Notwithstanding anything contained in this Rights
Agreement to the contrary, no supplement or amendment shall be made which
changes the Redemption Price and no supplement or amendment that changes the
rights and duties of the Rights Agent under this Agreement will be effective
against the Rights Agent without the execution of such supplement or amendment
by the Rights Agent. Prior to the Distribution Date, the interests of the
holders of Rights shall be deemed coincident with the interests of the holders
of Common Stock.

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

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

        30. Governing Law. This Rights Agreement 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 solely
by residents of such state and performed entirely within such state.

        31. Counterparts. This Rights 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.

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

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

                                  VIRAGE, INC.


                                   CERTIFICATE
                     OF DESIGNATION, PREFERENCES AND RIGHTS
                               OF THE TERMS OF THE
                            SERIES A PREFERRED STOCK


        Pursuant to Section 151 of the General Corporation Law of the State of
Delaware


        We, the President and Chief Executive Officer and the Secretary,
respectively, of Virage, Inc., organized and existing under the General
Corporation Law of the State of Delaware, in accordance with the provisions of
Section 103 thereof, DO HEREBY CERTIFY:

        That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the said Corporation, the said Board of
Directors on November 8, 2000, adopted the following resolution creating a
series of 200,000 shares of Preferred Stock designated as Series A Preferred
Stock:

        RESOLVED, that pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock of the Corporation be
and it hereby is created, and that the designation and amount thereof and the
powers, preferences and relative, participating, optional and other special
rights of the shares of such series, and the qualifications, limitations or
restrictions thereof are 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"), $.001
par value per share, and the number of shares constituting such series shall be
200,000.

        Section 2. Dividends and Distributions.

                (A) The dividend rate on the shares of Series A Preferred Stock
shall be for each quarterly dividend (hereinafter referred to as a "quarterly
dividend period"), which quarterly dividend periods shall commence on April 1,
July 1, October 1 and January 1 each fiscal year (each such date being referred
to herein as a "Quarterly Dividend Payment Date") (or in the case of original
issuance, from the date of original issuance) and shall end on and include the
day next preceding the first date of the next quarterly dividend period, at a
rate per quarterly dividend period (rounded to the nearest cent) equal to the
greater of (a) $2,500.00 or (b) subject to the provisions for adjustment
hereinafter set forth, 1,000 times the aggregate per share amount of all cash
dividends, and 1,000 times the aggregate per share amount (payable in cash,
based upon the fair market value at the time the non-cash dividend or other
distribution is declared as determined in good faith by the Board of Directors)
of all non-cash dividends or other



                                       1
<PAGE>   42

distributions other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared (but not withdrawn) on the Common Stock, par value $.001
per share, of the Corporation (the "Common Stock") during the immediately
preceding quarterly dividend period, or, with respect to the first quarterly
dividend period, since the first issuance of any share or fraction of a share of
Series A Preferred Stock. In the event this Corporation shall at any time after
December 5, 2000 (the "Rights Declaration Date") (i) declare any dividend on
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 amount to which holders of shares
of Series A Preferred Stock were entitled immediately prior to such event under
clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

                (B) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares 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 and be cumulative from such Quarterly Dividend Payment Date. Accrued but
unpaid dividends shall not bear interest. Dividends paid on the shares of Series
A Preferred Stock in an amount less than the total amount of such dividends at
the time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors may fix a record date for the determination of holders of shares of
Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than
forty-five (45) days prior to the date fixed for the payment thereof.

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

                (A) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 1,000 votes on all matters submitted to a vote of the stockholders of the
Corporation. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on 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 number of votes per share to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event shall be adjusted by
multiplying such number by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.



                                       2
<PAGE>   43

                (B) Except as otherwise provided herein, in the Certificate of
Incorporation or Bylaws, 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 stockholders of the Corporation.

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

        Section 4. 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.

        Section 5. Liquidation, Dissolution or Winding Up. In the event of any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, the holders of the Series A Preferred Stock shall be entitled to
receive the greater of (a) $100,000.00 per share, plus accrued dividends to the
date of distribution, whether or not earned or declared, or (b) an amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
1,000 times the aggregate amount to be distributed per share to holders of
Common Stock. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on 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 amount to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event pursuant to clause (b) of the preceding sentence
shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

        Section 6. 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 (subject to the provision for adjustment
hereinafter set forth) equal to 1,000 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on 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 amount set
forth in the preceding sentence with respect to the exchange or change of shares
of Series A Preferred Stock shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of



                                       3
<PAGE>   44

which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

        Section 7. No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

        Section 8. 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 have the benefit of all other rights of holders
of Series A Preferred Stock. All payments made with respect to fractional shares
hereunder shall be rounded to the nearest whole cent.

        Section 9. Certain Restrictions.

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

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

                        (iii) redeem or purchase or otherwise acquire for
        consideration shares of any stock ranking on a parity (either as to
        dividends or 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; or

                        (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.

<PAGE>   45

                (B) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this Section 9, purchase or otherwise acquire such shares at such time and in
such manner.

        Section 10. Ranking. The Series A Preferred Stock shall be 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 series shall provide
otherwise.

        Section 11. Amendment. The Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of
two-thirds or more of the outstanding shares of Series A Preferred Stock voting
together as a single class.

        IN WITNESS WHEREOF, we have executed and subscribed this Certificate and
do affirm the foregoing as true under the penalties of perjury this 8th day of
November, 2000.

        As provided in the Rights Agreement, the Purchase Price and the number
of shares of Preferred Stock or other securities which may be purchased upon the
exercise of the Rights evidenced by this Right Certificate are subject to
modification and adjustment upon the happening of certain events and, upon the
happening of certain events, securities other than shares of Preferred Stock, or
other property, may be acquired upon exercise of the Rights evidenced by this
Right Certificate, as provided by the Rights Agreement.

        Upon the occurrence of a Flip-In Event, if the Rights evidenced by this
Rights Certificate are beneficially owned by (i) an Acquiring Person or an
Affiliate or Associate of any such Acquiring Person, (ii) a transferee of any
such Acquiring Person, Associate or Affiliate, or (iii) under certain
circumstances specified in the Rights Agreement, a transferee of a person who,
after such transfer, became an Acquiring Person, or any Affiliate or Associate
of an Acquiring Person, such Rights shall be null and void and will no longer be
transferable and no holder hereof shall have any right with respect to such
Rights from and after the occurrence of such Flip-In Events.

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

        This Right Certificate, with or without other Right Certificates, upon
surrender at the principal office of the Rights Agent, may be exchanged for
another Right Certificate or Right Certificates of like tenor and date
evidencing Rights entitling the holder of record to purchase a like aggregate
number of shares of Preferred Stock as the Rights evidenced by the Right



                                       2

Certificate or Right Certificates surrendered shall have entitled such holder to
purchase. If this Right Certificate shall be exercised in part, the holder shall
be entitled to receive upon surrender hereof, another Right Certificate or Right
Certificates for the number of whole Rights not exercised.

        Subject to the provisions of the Rights Agreement, at any time prior to
the earlier of (i) the occurrence of a Flip-In Event (as such term is defined in
the Rights Agreement) or (ii) the Expiration Date (as such term is defined in
the Rights Agreement), the Rights evidenced by this Certificate may be redeemed
by the Company at its option at a redemption price of $.001 per Right. Subject
to the provisions of the Rights Agreement, the Company may, at its option, at
any time after a Flip-In Event, exchange all or part of the Rights evidenced by
this Certificate for shares of the Company's Common Stock or for Preferred Stock
(or shares of a class or series of the Company's preferred stock having the same
rights, privileges and preferences as the Preferred Stock).

        In the event (i) any person or group becomes an Acquiring Person or (ii)
any of the types of transactions, acquisitions or other events described above
as self-dealing transactions occur, and prior to the acquisition by such person
or group of 50% or more of the outstanding shares of Common Stock, the Board may
require all or any portion of the outstanding Rights (other than Rights owned by
such Acquiring Person which have become void) to be exchanged for Common Stock
on a pro rata basis, at an exchange ratio of one share of Common Stock or one
one-thousandth of a share of Preferred Stock (or of a share of a class or series
of the Company's Preferred Stock having equivalent rights, preferences and
privileges), per Right (subject to adjustment).

        No fractional shares of Preferred Stock shall be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-thousandth of a share of Preferred Stock, which
may, at the option of the Company, be evidenced by depository receipts), and no
fractional shares of Common Stock will be issued upon the exchange of any Right
or Rights evidenced hereby, and in lieu thereof, as provided in the Rights



                                       3
<PAGE>   49
Agreement, fractions of shares of Preferred Stock or Common Stock shall receive
an amount in cash equal to the same fraction of the then Current Market Price
(as such term is defined in the Rights Agreement) of a share of Preferred Stock
or Common Stock, as the case may be.

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

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

        WITNESS the facsimile signature of the proper officers of the Company
and its corporate seal. Dated as of _______________, 20___.

THEREOF WILL BE NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                                  VIRAGE, INC.

                               SUMMARY OF TERMS OF
                                RIGHTS AGREEMENT



NATURE OF RIGHT:                When exercisable, each Right (a "Right") will
                                initially entitle the holder to purchase one
                                one-thousandth of a share of Series A Preferred
                                Stock ("Preferred Stock") of Virage, Inc. (the
                                "Company").

MEANS OF DISTRIBUTION:          The Rights will be distributed to holders of the
                                Company's outstanding Common Stock as a dividend
                                of one Right for each share of Common Stock. The
                                Rights will also be attached to all future
                                issuances of Common Stock prior to the
                                Distribution Date (as defined below).

EXERCISABILITY:                 Rights become exercisable on the earlier of: (i)
                                the tenth day following the date of public
                                announcement by the Company or by any person or
                                group (an "Acquiring Person") that such person
                                or group has acquired beneficial ownership of
                                15% or more of the Company's outstanding Common
                                Stock, or (ii) the tenth business day (unless
                                extended by the Board prior to the time a person
                                becomes an Acquiring Person) following the
                                commencement, or announcement of an intention to
                                commence, by any person or group of a tender or
                                exchange offer which would result in such person
                                owning 15% or more of the outstanding Common
                                Stock of the Company (the earlier of such dates
                                being referred to as the "Distribution Date"),
                                provided that an Acquiring Person does not
                                include an Exempt Person (as such term is
                                defined in the Rights Agreement). Rights will
                                trade separately from the Common Stock once the
                                Rights become exercisable.

EXERCISE PRICE:                 $100.00 per one one-thousandth of a share of
                                Preferred Stock, which is the amount that in the
                                judgment of the Board of Directors represents
                                the long-term value of the Common Stock over the
                                term of the Rights Agreement (the "Purchase
                                Price").

TERM:                           The Rights will expire upon the earlier of (i)
                                ten years after the date of issuance, or
                                November 7, 2010 or (ii) redemption or exchange
                                by the Company as described below.

REDEMPTION OF RIGHTS:           Rights are redeemable at a price of $.001 per
                                Right, by the vote of the Company's Board of
                                Directors, at any time until the occurrence of a
                                Flip-In Event (defined below).

PREFERRED STOCK:                The Preferred Stock purchasable upon exercise of
                                the Rights will be nonredeemable and junior to
                                any other series of preferred stock the Company
                                may issue (unless otherwise provided in the
                                terms of such other series). Each share of
                                Preferred Stock will have a preferential



                                       1
<PAGE>   55

                                cumulative quarterly dividend in an amount equal
                                to the greater of (a) $2,500.00 or (b) 1,000
                                times the dividend declared on each share of
                                Common Stock. In the event of liquidation, the
                                holders of Preferred Stock will receive a
                                preferred liquidation payment equal to the
                                greater of (a) $100,000.00 per share, plus
                                accrued dividends to the date of distribution
                                whether or not earned or declared, or (b) an
                                amount per share equal to 1,000 times the
                                aggregate payment to be distributed per share of
                                Common Stock. Each share of Preferred Stock will
                                have 1,000 votes, voting together with the
                                shares of Common Stock. In the event of any
                                merger, consolidation or other transaction in
                                which shares of Common Stock are exchanged for
                                or changed into other securities, cash and/or
                                other property, each share of Preferred Stock
                                will be entitled to receive 1,000 times the
                                amount and type of consideration received per
                                share of Common Stock. The rights of the
                                Preferred Stock as to dividends, liquidation and
                                voting, and in the event of mergers and
                                consolidations, are protected by customary
                                anti-dilution provisions. Fractional shares (in
                                integral multiples of one one-thousandth) of
                                Preferred Stock will be issuable; however, the
                                Company may elect to distribute depositary
                                receipts in lieu of such fractional shares. In
                                lieu of fractional shares other than fractions
                                that are multiples of one one-thousandth of a
                                share, an adjustment in cash will be made based
                                on the market price of the Preferred Stock on
                                the last trading date prior to the date of
                                exercise. Because of the nature of the Preferred
                                Stock's dividend, liquidation and voting rights,
                                the value of one one-thousandth of a share of
                                Preferred Stock purchasable upon exercise of
                                each Right should approximate the value of one
                                share of Common Stock.
