        indirectly, by any other Person (or any Affiliate or Associate
        thereof) with which such Person (or any of such Person's Affiliates
        or Associates) has any agreement, arrangement or understanding
        (whether or not in writing), for the purpose of acquiring, holding,
        voting (except pursuant to a revocable proxy as described in the

        days and provided further, however, that any stockholder of the
        Company, with affiliate(s), associate(s) or other person(s) who may

        associated with such stockholder serving as directors or taking any

the tenth Business Day after the Stock Acquisition Date (or, if the tenth
Business Day after the Stock Acquisition Date occurs before the Record
Date, the close of business on the Record Date), or (ii) the close of
business on the tenth Business Day (or such later date as the Board shall
determine) after the date that a tender or exchange offer by any Person
(other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company, or any
Person or entity organized, appointed or established by the Company for or
pursuant to the terms of any such plan) is commenced within the meaning of

if upon consummation thereof, such Person would become an Acquiring Person,
in either instance other than pursuant to a Qualified Offer (the earlier of

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

                      (b) The Company will make available, as promptly as
practicable following the Record Date, a copy of a summary of the Rights,
in substantially the form attached hereto as Exhibit C (the "Summary of
Rights") to any holder Rights who may so request from time to time prior to
the Expiration Date. With respect to certificates for the Common Stock
outstanding as of the Record Date, until the Distribution Date, the Rights
will be evidenced by such certificates for the Common Stock and the
registered holders of the Common Stock shall also be the registered holders
of the associated Rights. Until the earlier of the Distribution Date or the
Expiration Date (as such term is defined in Section 7(a) hereof), the
transfer of any certificates representing shares of Common Stock in respect
of which Rights have been issued shall also constitute the transfer of the
Rights associated with such shares of Common Stock.

                      (c) Rights shall be issued in respect of all shares
of Common Stock which are issued (whether originally issued or from the
Company's treasury) after the Record Date but prior to the earlier of the
Distribution Date or the Expiration Date. Certificates representing such
shares of Common Stock shall also be deemed to be certificates for Rights,
and shall bear the following legend:

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

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

               Section 4.  Form of Rights Certificates.

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

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

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

               Section 5. Countersignature and Registration.

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

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

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

                      (a) Subject to the provisions of Section 4(b),
Section 7(e) and Section 14 hereof, at any time after the close of business
on the Distribution Date, and at or prior to the close of business on the
Expiration Date, any Rights Certificate or Certificates (other than Rights
Certificates representing Rights that may have been exchanged pursuant to
Section 24 hereof) may be transferred, split up, combined or exchanged for
another Rights Certificate or Certificates, entitling the registered holder
to purchase a like number of one one-thousandths of a share of Preferred
Stock (or, following a Triggering Event, Common Stock, other securities,
cash or other assets, as the case may be) as the Rights Certificate or
Certificates surrendered then entitles such holder (or former holder in the
case of a transfer) to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Rights Certificate or
Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Rights Certificate or Certificates to be
transferred, split up, combined or exchanged at the principal office or
offices of the Rights Agent designated for such purpose. Neither the Rights
Agent nor the Company shall be obligated to take any action whatsoever with
respect to the transfer of any such surrendered Rights Certificate until
the registered holder shall have completed and signed the certificate
contained in the form of assignment on the reverse side of such Rights
Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates
or Associates thereof as the Company shall reasonably request. Thereupon
the Rights Agent shall, subject to Section 4(b), Section 7(e), Section 14
hereof and Section 24 hereof, countersign and deliver to the Person
entitled thereto a Rights Certificate or Rights Certificates, as the case
may be, as so requested. The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Rights
Certificates.

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

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

                      (a) Subject to Section 7(e) hereof, at any time after
the Distribution Date the registered holder of any Rights Certificate may
exercise the Rights evidenced thereby (except as otherwise provided herein
including, without limitation, the restrictions on exercisability set forth
in Section 9(c), Section 11(a)(iii) and Section 23(a) hereof) in whole or
in part upon surrender of the Rights Certificate, with the form of election
to purchase and the certificate on the reverse side thereof duly executed,
to the Rights Agent at the principal office or offices of the Rights Agent
designated for such purpose, together with payment of the aggregate
Purchase Price with respect to the total number of one one-thousandths of a
share (or other securities, cash or other assets, as the case may be) as to
which such surrendered Rights are then exercisable, at or prior to the
earlier of (i) 5:00 P.M., Redwood City, California time, on August 18,
2010, or such later date as may be established by the Board of Directors
prior to the expiration of the Rights (such date, as it may be extended by
the Board, the ("Final Expiration Date")), or (ii) the time at which the
Rights are redeemed or exchanged as provided in Section 23 and Section 24
hereof (the earlier of (i) and (ii) being herein referred to as the
"Expiration Date").

                      (b) The Purchase Price for each one one-thousandth of
a share of Preferred Stock pursuant to the exercise of a Right shall
initially be five hundred dollars ($500), and shall be subject to
adjustment from time to time as provided in Section 11 and Section 13(a)
hereof and shall be payable in accordance with paragraph (c) below.

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

                      (d) In case the registered holder of any Rights
Certificate shall exercise less than all the Rights evidenced thereby, a
new Rights Certificate evidencing Rights equivalent to the Rights remaining
unexercised shall be issued by the Rights Agent and delivered to, or upon
the order of, the registered holder of such Rights Certificate, registered
in such name or names as may be designated by such holder, subject to the
provisions of Section 14 hereof.

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

                      (f) Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder upon the
occurrence of any purported 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 Rights Certificate surrendered for such exercise, and (ii) provided
such additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) or Affiliates or Associates thereof as the Company shall
reasonably request.

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

               Section 9. Reservation and Availability of Capital Stock.

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

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

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

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

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

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

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

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

                             (ii) In the event any Person shall, at any time
        after the Rights Dividend Declaration Date, become an Acquiring
        Person, unless the event causing such Person to become an Acquiring
        Person is a transaction set forth in Section 13(a) hereof, or is an
        acquisition of shares of Common Stock pursuant to a tender offer or
        an exchange offer for all outstanding shares of Common Stock at a
        price and on terms determined by at least a majority of the members
        of the Board of Directors who are not officers of the Company and
        who are not representatives, nominees, Affiliates or Associates of
        an Acquiring Person, after receiving advice from one or more
        investment banking firms, to be (a) at a price which is fair to
        stockholders and not inadequate (taking into account all factors
        which such members of the Board deem relevant, including, without
        limitation, prices which could reasonably be achieved if the
        Company or its assets were sold on an orderly basis designed to
        realize maximum value) and (b) otherwise in the best interests of
        the Company and its stockholders (a "Qualified Offer").

then, promptly following the occurrence of such event, proper provision
shall be made so that each holder of a Right (except as provided below and
in Section 7(e) hereof) shall thereafter have the right to receive, upon
exercise thereof at the then current Purchase Price in accordance with the
terms of this Agreement, in lieu of a number of one one-thousandths of a
share of Preferred Stock, such number of shares of Common Stock of the
Company as shall equal the result obtained by (x) multiplying the then
current Purchase Price by the then number of one one-thousandths of a share
of Preferred Stock for which a Right was exercisable immediately prior to
the first occurrence of a Section 11(a)(ii) Event, and (y) dividing that
product (which, following such first occurrence, shall thereafter be
referred to as the "Purchase Price" for each Right and for all purposes of
this Agreement) by 50% of the Current Market Price (determined pursuant to
Section 11(d) hereof) per share of Common Stock on the date of such first
occurrence (such number of shares, the "Adjustment Shares").
Notwithstanding anything in this Agreement to the contrary, (i) the
execution of the Merger Agreement, (ii) the execution of the Company Stock
Option Agreement or (iii) the consummation of the transactions contemplated
by the Merger Agreement or the company Stock Option Agreement, shall not be
deemed to be a Section 11(a)(ii) event and shall not cause the Rights to be
adjusted or exercisable under this Agreement.

                             (iii) In the event that the number of shares
        of Common Stock which are authorized by the Company's Amended
        andRestated Certificate of Incorporation, but which are not
        outstanding or reserved for issuance for purposes other than upon
        exercise of the Rights, are not sufficient to permit the exercise
        in full of the Rights in accordance with the foregoing subparagraph
        (ii) of this Section 11(a), the Company shall (A) determine the
        value of the Adjustment Shares issuable upon the exercise of a
        Right (the "Current Value"), and (B) with respect to each Right
        (subject to Section 7(e) hereof), make adequate provision to
        substitute for the Adjustment Shares, upon the exercise of a Right
        and payment of the applicable Purchase Price, (1) cash, (2) a
        reduction in the Purchase Price, (3) Common Stock or other equity
        securities of the Company (including, without limitation, shares,
        or units of shares, of preferred stock, such as the Preferred
        Stock, which the Board has deemed to have essentially the same
        value or economic rights as shares of Common Stock (such shares of
        preferred stock being referred to as "Common Stock Equivalents")),
        (4) debt securities of the Company, (5) other assets, or (6) any
        combination of the foregoing, having an aggregate value equal to
        the Current Value (less the amount of any reduction in the Purchase
        Price), where such aggregate value has been determined by the Board
        based upon the advice of a nationally recognized investment banking
        firm selected by the Board; provided, however, that if the Company
        shall not have made adequate provision to deliver value pursuant to
        clause (B) above within thirty (30) days following the later of (x)
        the first occurrence of a Section 11(a)(ii) Event and (y) the date
        on which the Company's right of redemption pursuant to Section
        23(a) expires (the later of (x) and (y) being referred to herein as
        the "Section 11(a)(ii) Trigger Date"), then the Company shall be
        obligated to deliver, upon the surrender for exercise of a Right
        and without requiring payment of the Purchase Price, shares of
        Common Stock (to the extent available) and then, if necessary,
        cash, which shares and/or cash have an aggregate value equal to the
        Spread. For purposes of the preceding sentence, the term "Spread"
        shall mean the excess of (i) the Current Value over (ii) the
        Purchase Price. If the Board determines in good faith that it is
        likely that sufficient additional shares of Common Stock could be
        authorized for issuance upon exercise in full of the Rights, the
        thirty (30) day period set forth above may be extended to the
        extent necessary, but not more than ninety (90) days after the
        Section 11(a)(ii) Trigger Date, in order that the Company may seek
        stockholder approval for the authorization of such additional
        shares (such thirty (30) day period, as it may be extended, is
        herein called the "Substitution Period"). To the extent that action
        is to be taken pursuant to the first and/or third sentences of this
        Section 11(a)(iii), the Company (1) shall provide, subject to
        Section 7(e) hereof, that such action shall apply uniformly to all
        outstanding Rights, and (2) may suspend the exercisability of the
        Rights until the expiration of the Substitution Period in order to
        seek such stockholder approval for such authorization of additional
        shares and/or to decide the appropriate form of distribution to be
        made pursuant to such first sentence and to determine the value
        thereof. In the event of any such suspension, the Company shall
        issue a public announcement stating that the exercisability of the
        Rights has been temporarily suspended, as well as a public
        announcement at such time as the suspension is no longer in effect.
        For purposes of this Section 11(a)(iii), the value of each
        Adjustment Share shall be the current market price per share of the
        Common Stock on the Section 11(a)(ii) 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.

                      (b) In case the Company shall fix a record date for
the issuance of rights, options or warrants to all holders of Preferred
Stock entitling them to subscribe for or purchase (for a period expiring
within forty-five (45) calendar days after such record date) Preferred
Stock (or shares having the same rights, privileges and preferences as the
shares of Preferred Stock ("Equivalent Preferred Stock")) or securities
convertible into Preferred Stock or Equivalent Preferred Stock at a price
per share of Preferred Stock or per share of Equivalent Preferred Stock (or
having a conversion price per share, if a security convertible into
Preferred Stock or Equivalent Preferred Stock) less than the Current Market
Price (as determined pursuant to Section 11(d) hereof) per share of
Preferred Stock on such record date, the Purchase Price to be in effect
after such record date shall be determined by multiplying the Purchase
Price in effect immediately prior to such record date by a fraction, the
numerator of which shall be the number of shares of Preferred Stock
outstanding on such record date, plus the number of shares of Preferred
Stock which the aggregate offering price of the total number of shares of
Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or
the aggregate initial conversion price of the convertible securities so to
be offered) would purchase at such Current Market Price, and the
denominator of which shall be the number of shares of Preferred Stock
outstanding on such record date, plus the number of additional shares of
Preferred Stock and/or Equivalent Preferred Stock to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible). In case such subscription price may be
paid by delivery of consideration, part or all of which may be in a form
other than cash, the value of such consideration shall be as determined in
good faith by the Board of Directors of the Company, whose determination
shall be described in a statement filed with the Rights Agent and shall be
binding on the Rights Agent and the holders of the Rights. 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
(other than a regular quarterly cash dividend out of the earnings or
retained earnings of the Company), assets (other than a dividend payable in
Preferred Stock, but including any dividend payable in stock other than
Preferred Stock) or evidences of indebtedness, or of subscription rights or
warrants (excluding those referred to in Section 11(b) hereof), the
Purchase Price to be in effect after such record date shall be determined
by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the Current
Market Price (as determined pursuant to Section 11(d) hereof) per share of
Preferred Stock on such record date, less the fair market value (as
determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights
Agent) of the portion of the cash, assets or evidences of indebtedness so
to be distributed or of such subscription rights or warrants applicable to
a share of Preferred Stock, and the denominator of which shall be such
Current Market Price (as determined pursuant to Section 11(d) hereof) per
share of Preferred Stock. Such adjustments shall be made successively
whenever such a record date is fixed, and in the event that such
distribution is not so made, the Purchase Price shall be adjusted to be the
Purchase Price which would have been in effect if such record date had not
been fixed.

                      (d)(i) For the purpose of any computation hereunder,
other than computations made pursuant to Section 11(a)(iii) hereof, the
Current Market Price per share of Common Stock on any date shall be deemed
to be the average of the daily closing prices per share of such Common
Stock for the thirty (30) consecutive Trading Days immediately prior to
such date, and for purposes of computations made pursuant to Section
11(a)(iii) hereof, the Current Market Price per share of Common Stock on
any date shall be deemed to be the average of the daily closing prices per
share of such Common Stock for the ten (10) consecutive Trading Days
immediately following such date; provided, however, that in the event that
the Current Market Price per share of the Common Stock is determined during
a period following the announcement by the issuer of such Common Stock of
(A) a dividend or distribution on such Common Stock payable in shares of
such Common Stock or securities convertible into shares of such Common
Stock (other than the Rights), or (B) any subdivision, combination or
reclassification of such Common Stock, and the ex-dividend date for such
dividend or distribution, or the record date for such subdivision,
combination or reclassification shall not have occurred prior to the
commencement of the requisite thirty (30) Trading Day or ten (10) Trading
Day period, as set forth above, then, and in each such case, the Current
Market Price shall be properly adjusted to take into account ex-dividend
trading. The closing price for each day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average
of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with
respect to securities listed or admitted to trading on the New York Stock
Exchange or, if the shares of Common Stock are not listed or admitted to
trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed
on the principal national securities exchange on which the shares of Common
Stock are listed or admitted to trading or, if the shares of Common Stock
are not listed or admitted to trading on any national securities exchange,
the last quoted price or, if not so quoted, the average of the high bid and
low asked prices in the over-the-counter market, as reported by the
National Association of Securities Dealers Automated Quotation System
("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. 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
shall be used. The term "Trading Day" shall mean a day on which the
principal national securities exchange on which the shares of Common Stock
are listed or admitted to trading is open for the transaction of business
or, if the shares of Common Stock are not listed or admitted to trading on
any national securities exchange, a Business Day. If the Common Stock is
not publicly held or not so listed or traded, Current Market Price per
share shall mean the fair value per share as determined in good faith by
the Board, whose determination shall be described in a statement filed with
the Rights Agent and shall be conclusive for all purposes.

                             (ii) For the purpose of any computation
        hereunder, the Current Market Price per share of Preferred Stock
        shall be determined in the same manner as set forth above for the
        Common Stock in clause (i) of this Section 11(d) (other than the
        last sentence thereof). If the Current Market Price per share of
        Preferred Stock cannot be determined in the manner provided above
        or if the Preferred Stock is not publicly held or listed or traded
        in a manner described in clause (i) of this Section 11(d), the
        Current Market Price per share of Preferred Stock shall be
        conclusively deemed to be an amount equal to one thousand (1000)
        (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. If neither the Common Stock nor the Preferred Stock is
        publicly held or so listed or traded, Current Market Price per
        share of the Preferred Stock shall mean the fair value per share as
        determined in good faith by the Board, whose determination shall be
        described in a statement filed with the Rights Agent and shall be
        conclusive for all purposes. For all purposes of this Agreement,
        the Current Market Price of a Unit shall be equal to the Current
        Market Price of one share of Preferred Stock divided by one
        thousand (1000).

                      (e) Anything herein to the contrary notwithstanding,
no adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least one percent
(1%) in the Purchase Price; provided, however, that any adjustments which
by reason of this Section 11(e) are not required to be made shall be
carried forward and taken into account in any subsequent adjustment. All
calculations under this Section 11 shall be made to the nearest cent or to
the nearest ten-thousandth of a share of Common Stock or other share or
one-millionth 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 (3) years from the date of the transaction which mandates such
adjustment, or (ii) the Expiration Date.

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

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

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

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

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

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

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

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

                      (n) The Company covenants and agrees that it shall
not, at any time after the Distribution Date, (i) consolidate with any
other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), (ii) merge with or into any other
Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), or (iii) sell or transfer (or permit
any Subsidiary to sell or transfer), in one transaction, or a series of
related transactions, assets, cash flow or earning power aggregating more
than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person or Persons (other than the Company
and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), if (x) at the time of or immediately
after such consolidation, merger or sale there are any rights, warrants or
other instruments or securities outstanding or agreements in effect which
would substantially diminish or otherwise eliminate the benefits intended
to be afforded by the Rights or (y) prior to, simultaneously with or
immediately after such consolidation, merger or sale, the shareholders of
the Person who constitutes, or would constitute, the "Principal Party" for
purposes of Section 13(a) hereof shall have received a distribution of
Rights previously owned by such Person or any of its Affiliates and
Associates.

                      (o) The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Section 23 or
Section 26 hereof, take (or permit any Subsidiary to take) any action if at
the time such action is taken it is reasonably foreseeable that such action
will diminish substantially or otherwise eliminate the benefits intended to
be afforded by the Rights.

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

               Section 12. Certificate of Adjusted Purchase Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11 and
Section 13 hereof, the Company shall (a) promptly prepare a certificate
setting forth such adjustment and a brief statement of the facts accounting
for such adjustment, (b) promptly file with the Rights Agent, and with each
transfer agent for the Preferred Stock and the Common Stock, a copy of such
certificate and (c) if a Distribution Date has occurred, mail a brief
summary thereof to each holder of a Rights Certificate in accordance with
Section 27 hereof. The Rights Agent shall be fully protected in relying on
any such certificate and on any adjustment therein contained.

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

                      (a) In the event that, following the Stock
Acquisition Date, directly or indirectly, (x) the Company shall consolidate
with, or merge with and into, any other Person (other than a Subsidiary of
the Company in a transaction which complies with Section 11(o) hereof), and
the Company shall not be the continuing or surviving corporation of such
consolidation or merger, (y) any Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) hereof) shall
consolidate with, or merge with or into, the Company, and the Company shall
be the continuing or surviving corporation of such consolidation or merger
and, in connection with such consolidation or merger, all or part of the
outstanding shares of Common Stock shall be changed into or exchanged for
stock or other securities of any other Person or cash or any other
property, or (z) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one
transaction or a series of related transactions, assets, cash flow or
earning power aggregating more than 50% of the assets, cash flow or earning
power of the Company and its Subsidiaries (taken as a whole) to any Person
or Persons (other than the Company or any Subsidiary of the Company in one
or more transactions each of which complies with Section 11(o) hereof),
then, and in each such case (except as may be contemplated by Section 13(d)
hereof), proper provision shall be made so that: (i) each holder of a
Right, except as provided in Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof at the then current Purchase
Price in accordance with the terms of this Agreement, such number of
validly authorized and issued, fully paid, non-assessable and freely
tradeable shares of Common Stock of the Principal Party (as such term is
hereinafter defined), not subject to any liens, encumbrances, rights of
first refusal or other adverse claims, as shall be equal to the result
obtained by (1) multiplying the then current Purchase Price by the number
of one one-thousandths of a share of Preferred Stock for which a Right is
exercisable immediately prior to the first occurrence of a Section 13 Event
(or, if a Section 11(a)(ii) Event has occurred prior to the first
occurrence of a Section 13 Event, multiplying the number of such one
one-thousandths of a share for which a Right was exercisable immediately
prior to the first occurrence of a Section 11(a)(ii) Event by the Purchase
Price in effect immediately prior to such first occurrence), and dividing
that product (which, following the first occurrence of a Section 13 Event,
shall be referred to as the "Purchase Price" for each Right and for all
purposes of this Agreement) by (2) 50% of the Current Market Price
(determined pursuant to Section 11(d)(i) hereof) per share of the Common
Stock of such Principal Party on the date of consummation of such Section
13 Event; (ii) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such Section 13 Event, all the obligations and
duties of the Company pursuant to this Agreement; (iii) the term "Company"
shall thereafter be deemed to refer to such Principal Party, it being
specifically intended that the provisions of Section 11 hereof shall apply
only to such Principal Party following the first occurrence of a Section 13
Event; (iv) such Principal Party shall take such steps (including, but not
limited to, the reservation of a sufficient number of shares of its Common
Stock) in connection with the consummation of any such transaction as may
be necessary to assure that the provisions hereof shall thereafter be
applicable, as nearly as reasonably may be, in relation to its shares of
Common Stock thereafter deliverable upon the exercise of the Rights; and
(v) the provisions of Section 11(a)(ii) hereof shall be of no effect
following the first occurrence of any Section 13 Event.

                     (b) "Principal Party" shall mean:

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

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

provided, however, that in any such case, (1) if the Common Stock of such
Person is not at such time and has not been continuously over the preceding
twelve (12) month period registered under Section 12 of the Exchange Act,
and such Person is a direct or indirect Subsidiary of another Person the
Common Stock of which is and has been so registered, "Principal Party"
shall refer to such other Person; and (2) in case such Person is a
Subsidiary, directly or indirectly, of more than one Person, the Common
Stocks of two or more of which are and have been so registered, "Principal
Party" shall refer to whichever of such Persons is the issuer of the Common
Stock having the greatest aggregate market value.

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

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

                             (ii) take such all such other action as may be
        necessary to enable the Principal Party to issue the securities
        purchasable upon exercise of the Rights, including but not limited
        to the registration or qualification of such securities under all
        requisite securities laws of jurisdictions of the various states
        and the listing of such securities on such exchanges and trading
        markets as may be necessary or appropriate; and

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

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

                      (d) Notwithstanding anything in this Agreement to the
contrary, Section 13 shall not be applicable to a transaction described in
subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is
consummated with a Person or Persons who acquired shares of Common Stock
pursuant to a tender offer or exchange offer for all outstanding shares of
Common Stock which is a Qualified Offer as such term is defined in Section
11(a)(ii) hereof (or a wholly owned subsidiary of any such Person or
Persons), (ii) the price per share of Common Stock offered in such
transaction is not less than the price per share of Common Stock paid to
all holders of shares of Common Stock whose shares were purchased pursuant
to such tender offer or exchange offer and (iii) the form of consideration
being offered to the remaining holders of shares of Common Stock pursuant
to such transaction is the same as the form of consideration paid pursuant
to such tender offer or exchange offer. Notwithstanding anything in this
Agreement to the contrary, (i) the execution of the Merger Agreement, (ii)
the execution of the Company Stock Option Agreement or (iii) the
consummation of the transactions contemplated by the Merger Agreement or
the company Stock Option Agreement, shall not be deemed to be a Section 13
Event and shall not cause the Rights to be adjusted or exercisable under
this Agreement. Upon consummation of any such transaction contemplated by
this Section 13(d) (other than the Merger), all Rights hereunder shall
expire.

               Section 14. Fractional Rights and Fractional Shares.

                      (a) The Company shall not be required to issue
fractions of Rights, except prior to the Distribution Date as provided in
Section 11(p) hereof, or to distribute Rights Certificates which evidence
fractional Rights. In lieu of such fractional Rights, the Company shall pay
to the registered holders of the Rights Certificates with regard to which
such fractional Rights would otherwise be issuable, an amount in cash equal
to the same fraction of the current market value of a whole Right. For
purposes of this Section 14(a), the current market value of a whole Right
shall be the closing price of the Rights for the Trading Day immediately
prior to the date on which such fractional Rights would have been otherwise
issuable. The closing price of the Rights for any day shall be the last
sale price, regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices, regular way, in either
case as reported in the principal consolidated transaction reporting system
with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the Rights are not listed or admitted to trading on
the New York Stock Exchange, as reported in the principal consolidated
transaction reporting system with respect to securities listed on the
principal national securities exchange on which the Rights are listed or
admitted to trading, or if the Rights are not listed or admitted to trading
on any national securities exchange, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the
over-the-counter market, as reported by NASDAQ or such other system then in
use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished
by a professional market maker making a market in the Rights, selected by
the Board of Directors of the Company. If on any such date no such market
maker is making a market in the Rights, the fair value of the Rights on
such date as determined in good faith by the Board of Directors of the
Company shall be used.

                      (b) The Company shall not be required to issue
fractions of shares of Preferred Stock (other than fractions which are
integral multiples of one one-thousandth of a share of Preferred Stock)
upon exercise of the Rights or to distribute certificates which evidence
fractional shares of Preferred Stock (other than fractions which are
integral multiples of one one-thousandth of a share of Preferred Stock). In
lieu of fractional shares of Preferred Stock that are not integral
multiples of one one-thousandth of a share of Preferred Stock, the Company
may pay to the registered holders of Rights Certificates at the time such
Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one one-thousandth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market
value of one one-thousandth of a share of Preferred Stock shall be one
one-thousandth of the closing price of a share of Preferred Stock (as
determined pursuant to Section 11(d)(ii) hereof) for the Trading Day
immediately prior to the date of such exercise.

                      (c) Following the occurrence of a Triggering Event,
the Company shall not be required to issue fractions of shares of Common
Stock upon exercise of the Rights or to distribute certificates which
evidence fractional shares of Common Stock. In lieu of fractional shares of
Common Stock, the Company may pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an
amount in cash equal to the same fraction of the current market value of
one (1) share of Common Stock. For purposes of this Section 14(c), the
current market value of one share of Common Stock shall be the closing
price of one share of Common Stock (as determined pursuant to Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

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

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

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

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

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

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

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

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

               Section 18. Concerning the Rights Agent.

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

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

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

                      (a) Any corporation into which the Rights Agent or
any successor Rights Agent may be merged or with which it may be
consolidated, or any corporation resulting from any merger or consolidation
to which the Rights Agent or any successor Rights Agent shall be a party,
or any corporation succeeding to the corporate trust, stock transfer or
other shareholder services 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; but only if such corporation
would be eligible for appointment as a successor Rights Agent under the
provisions of Section 21 hereof. In case at the time such successor Rights
Agent shall succeed to the agency created by this Agreement, any of the
Rights Certificates shall have been countersigned but not delivered, any
such successor Rights Agent may adopt the countersignature of a predecessor
Rights Agent and deliver such Rights Certificates so countersigned; and in
case at that time any of the Rights Certificates shall not have been
countersigned, any successor Rights Agent may countersign such Rights
Certificates either in the name of the predecessor or in the name of the
successor Rights Agent; and in all such cases such Rights Certificates
shall have the full force provided in the Rights Certificates and in this
Agreement.

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

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

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

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

                      (c) The Rights Agent shall be liable hereunder only
for its own negligence, bad faith or willful misconduct.

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

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

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

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

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

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

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

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

               Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under
this Agreement upon thirty (30) days' notice in writing mailed to the
Company, and to each transfer agent of the Common Stock and Preferred
Stock, by registered or certified mail, and, if such resignation occurs
after the Distribution Date, to the registered holders of the Rights
Certificates by first-class mail. The Company may remove the Rights Agent
or any successor Rights Agent upon thirty (30) days' notice in writing,
mailed to the Rights Agent or successor Rights Agent, as the case may be,
and to each transfer agent of the Common Stock and Preferred Stock, by
registered or certified mail, and, if such removal occurs after the
Distribution Date, to the holders of the Rights Certificates by first-class
mail. If the Rights Agent shall resign or be removed or shall otherwise
become incapable of acting, the Company shall appoint a successor to the
Rights Agent. If the Company shall fail to make such appointment within a
period of thirty (30) days after giving notice of such removal or after it
has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Rights
Certificate (who shall, with such notice, submit his Rights Certificate for
inspection by the Company), then any registered holder of any Rights
Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be a legal business
entity organized and doing business under the laws of the United States or
of the State of California or of any other state of the United States, in
good standing, having an office in the State of California, which is
authorized under such laws to exercise corporate trust or stock transfer or
shareholder services powers and which has at the time of its appointment as
Rights Agent a combined capital and surplus of at least $50,000,000 or (b)
an affiliate of a legal business entity described in clause (a) of this
sentence. After appointment, the successor Rights Agent shall be vested
with the same powers, rights, duties and responsibilities as if it had been
originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and
deliver any further assurance, conveyance, act or deed necessary for the
purpose. Not later than the effective date of any such appointment, the
Company shall file notice thereof in writing with the predecessor Rights
Agent and each transfer agent of the Common Stock and the Preferred Stock,
and, if such appointment occurs after the Distribution Date, mail a notice
thereof in writing to the registered holders of the Rights Certificates.
Failure to give any notice provided for in this Section 21, however, or any
defect therein, shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the
successor Rights Agent, as the case may be.

               Section 22. Issuance of New Rights Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to
the contrary, the Company may, at its option, issue new Rights Certificates
evidencing Rights in such form as may be approved by the Board of Directors
to reflect any adjustment or change in the Purchase Price and the number or
kind or class of shares or other securities or property purchasable under
the Rights Certificates made in accordance with the provisions of this
Agreement. 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 (a) 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, granted or awarded as of the
Distribution Date, or upon the exercise, conversion or exchange of
securities hereafter issued by the Company, and (b) may, in any other case,
if deemed necessary or appropriate by the Board of Directors of the
Company, issue Rights Certificates representing the appropriate number of
Rights in connection with such issuance or sale; provided, however, that
(i) no such Rights Certificate shall be issued if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax consequences to the Company or the
Person to whom such Rights Certificate would be issued, and (ii) no such
Rights Certificate shall be issued if, and to the extent that, appropriate
adjustment shall otherwise have been made in lieu of the issuance thereof.

               Section 23. Redemption and Termination.

                      (a) The Board of Directors of the Company may, at its
option, at any time prior to the earlier of (i) the close of business on
the tenth Business Day following the Stock Acquisition Date (or, if the
Stock Acquisition Date shall have occurred prior to the Record Date, the
close of business on the tenth Business Day following the Record Date), or
(ii) the Final Expiration Date, redeem all but not less than all of 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").
Notwithstanding anything contained in this Agreement to the contrary, the
Rights shall not be exercisable after the first occurrence of a Section
11(a)(ii) Event until such time as the Company's right of redemption
hereunder has expired. The Company may, at its option, pay the Redemption
Price in cash, shares of Common Stock (based on the Current Market Price,
as defined in Section 11(d)(i) hereof, of the Common Stock at the time of
redemption) or any other form of consideration deemed appropriate by the
Board of Directors.

                      (b) Immediately upon the action of the Board of
Directors of the Company ordering the redemption of the Rights, evidence of
which shall have been filed with the Rights Agent and without any further
action and without any notice, the right to exercise the Rights will
terminate and the only right thereafter of the holders of Rights shall be
to receive the Redemption Price for each Right so held. Promptly after the
action of the Board of Directors ordering the redemption of the Rights, the
Company shall give notice of such redemption to the Rights Agent and the
holders of the then outstanding Rights by mailing such notice to all such
holders at each holder's last address as it appears upon the registry books
of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent for the Common Stock. Any notice which is
mailed in the manner herein provided shall be deemed given, whether or not
the holder receives the notice. Each such notice of redemption will state
the method by which the payment of the Redemption Price will be made.

               Section 24.  Exchange.

                      (a) The Board of Directors of the Company may, at its
option, at any time after any Person becomes an Acquiring Person, exchange
all or part of the then outstanding and exercisable Rights (which shall not
include Rights that have become void pursuant to the provisions of Section
7(e) hereof) for 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 of the Company shall
not be empowered to effect such exchange at any time after any Person
(other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding
Common Stock for or pursuant to the terms of any such plan), together with
all Affiliates and Associates of such Person, becomes the Beneficial Owner
of 50% or more of the Common Stock then outstanding.

                      (b) Immediately upon the action of the Board of
Directors of the Company ordering the exchange of any Rights pursuant to
subsection (a) of this Section 24 and without any further action and
without any notice, the right to exercise such Rights shall terminate and
the only right thereafter of a holder of such Rights shall be to receive
that number of 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 Common Stock for Rights
will be effected and, in the event of any partial exchange, the number of
Rights which will be exchanged. Any partial exchange shall be effected pro
rata based on the number of Rights (other than Rights which have become
void pursuant to the provisions of Section 7(e) hereof) held by each holder
of Rights.

                      (c) In any exchange pursuant to this Section 24, the
Company, at its option, may substitute Preferred Stock (or Equivalent
Preferred Stock, as such term is defined in paragraph (b) of Section 11
hereof) for Common Stock exchangeable for Rights, at the initial rate of
one one-thousandth of a share of Preferred Stock (or Equivalent Preferred
Stock) for each share of Common Stock, as appropriately adjusted to reflect
stock splits, stock dividends and other similar transactions after the date
hereof.

                      (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 shares of Company shall take all such action as
may 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, there shall be paid to the registered holders of
the Rights 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 subsection (e), the current market value of a
whole share of Common Stock shall be the closing price of a share of Common
Stock (as determined pursuant to the second sentence of Section 11(d)(i)
hereof) for the Trading Day immediately prior to the date of exchange
pursuant to this Section 24.

               Section 25. Notice of Certain Events.

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

                      (b) In case any of the events set forth in Section
11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall
as soon as practicable thereafter give to each holder of a Rights
Certificate, to the extent feasible and in accordance with Section 26
hereof, a notice of the occurrence of such event, which shall specify the
event and the consequences of the event to holders of Rights under Section
11(a)(ii) hereof, and (ii) all references in the preceding paragraph to
Preferred Stock shall be deemed thereafter to refer to Common Stock and/or,
if appropriate, other securities.

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

Subject to the provisions of Section 21, any notice or demand authorized by
this Agreement to be given or made by the Company or by the holder of any
Rights Certificate to or on the Rights Agent shall be sufficiently given or
made if sent by first-class mail, postage prepaid, addressed (until another
address is filed in writing by the Rights Agent with the Company) as
follows:

                      U.S. Stock Transfer Corporation
                            1745 Gardena Avenue
                          Glendale, CA 91204-2991
                   Attention: Corporate Trust Department

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

               Section 27. Supplements and Amendments. Prior to the
Distribution Date, and subject to the penultimate sentence of this Section
27, the Company and the Rights Agent shall, if the Company so directs,
supplement or amend any provision of this Agreement without the approval of
any holders of certificates representing shares of Common Stock. From and
after the Distribution Date, the Company 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 (i) to cure any ambiguity,
(ii) to correct or supplement any provision contained herein which may be
defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder, or (iv) to change or
supplement the provisions hereunder in any manner which the Company may
deem necessary or desirable and which shall not adversely affect the
interests of the holders of Rights Certificates (other than an Acquiring
Person or an Affiliate or Associate of an Acquiring Person); provided, this
Agreement may not be supplemented or amended to lengthen any time period
hereunder other than a time period related to when the Rights may be
redeemed, pursuant to clause (iii) of this sentence, unless such
lengthening is for the purpose of protecting, enhancing or clarifying the
rights of, and/or the benefits to, the holders of Rights. Upon the delivery
of a certificate from an appropriate officer of the Company which states
that the proposed supplement or amendment is in compliance with the terms
of this Section 27, the Rights Agent shall execute such supplement or
amendment. 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. Notwithstanding anything herein to the contrary, this
Agreement may not be amended at a time when the Rights are not redeemable.

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

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

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

               Section 31. Severability. If any term, provision, covenant
or restriction of this Agreement is held by a court of competent
jurisdiction or other authority to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated; provided, however, that notwithstanding
anything in this Agreement to the contrary, if any such term, provision,
covenant or restriction is held by such court or authority to be invalid,
void or unenforceable and the Board of Directors of the Company determines
in its good faith judgment that severing the invalid language from this
Agreement would adversely affect the purpose or effect of this Agreement,
the right of redemption set forth in Section 23 hereof shall be reinstated
and shall not expire until the close of business on the tenth Business Day
following the date of such determination by the Board of Directors. Without
limiting the foregoing, if any provision requiring a specific group of
Directors of the Company to act is held to by any court of competent
jurisdiction or other authority to be invalid, void or unenforceable, such
determination shall then be made by the Board of Directors of the Company
in accordance with applicable law and the Company's Amended and Restated
Certificate of Incorporation and Bylaws.

               Section 32. Governing Law. This Agreement, each Right and
each Rights 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 made and to be performed entirely within such
State.

               Section 33. Counterparts. This Agreement may be executed in
any number of counterparts and each of such counterparts shall for all
purposes be deemed to be an original, and all such counterparts shall
together constitute but one and the same instrument.

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


               IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed all as of the day and year first above
written.

                              PHONE.COM, INC.


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


               We, Alain Rossmann, Chairman of the Board, and Alan Black,
Vice President, Finance and Administration, Chief Financial Officer and
Treasurer, of Phone.com, Inc., a corporation 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 Amended and Restated Certificate of Incorporation of the
said Corporation, the said Board of Directors on August 8, 2000, adopted
the following resolution creating a series of 250,000 shares of Preferred
Stock designated as Series A Junior Participating Preferred Stock:

               RESOLVED, that pursuant to the authority vested in the Board
of Directors of this Corporation in accordance with the provisions of its
Amended and Restated 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 voting 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 Junior Participating Preferred Stock" and
the number of shares constituting such series shall be 250,000.

               Section 2.  Dividends and Distributions.

               (A) Subject to the prior and superior rights of the holders
of any shares of any series of Preferred Stock ranking prior and superior
to the shares of Series A Junior Participating Preferred Stock with respect
to dividends, the holders of shares of Series A Junior Participating
Preferred Stock shall be entitled to receive, when, as and if declared by
the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash on the March 31, June 30, September 30,
and December 31 in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly
Dividend Payment Date after the first issuance of a share or fraction of a
share of Series A Junior Participating Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $.01 or (b)
subject to the provision for adjustment hereinafter set forth, one thousand
(1000) times the aggregate per share amount of all cash dividends, and one
thousand (1000) times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions other than a dividend payable
in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common
Stock, par value $0.001 per share, of the Corporation (the "Common Stock")
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Junior
Participating Preferred Stock. In the event the Corporation shall at any
time after August 8, 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 Junior Participating Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such
event.

               (B) The Corporation shall declare a dividend or distribution
on the Series A Junior Participating Preferred Stock as provided in
Paragraph (A) above immediately after it declares a dividend or
distribution on the Common Stock (other than a dividend payable in shares
of Common Stock); provided that, in the event no dividend or distribution
shall have been declared on the Common Stock during the period between any
Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend
Payment Date, a dividend of $.01 per share on the Series A Junior
Participating Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

               (C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from
the Quarterly Dividend Payment Date next preceding the date of issue of
such shares of Series A Junior Participating Preferred Stock, unless the
date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such shares
shall begin to accrue from the date of issue of such shares, or unless the
date of issue is a Quarterly Dividend Payment Date or is a date after the
record date for the determination of holders of shares of Series A Junior
Participating Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue 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 Junior Participating
Preferred Stock in an amount less than the total amount of such dividends
at the time accrued and payable on such shares shall be allocated pro rata
on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of
holders of shares of Series A Junior Participating Preferred Stock entitled
to receive payment of a dividend or distribution declared thereon, which
record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

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

               (A) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Junior Participating Preferred Stock shall
entitle the holder thereof to one thousand (1000) 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
Junior Participating Preferred Stock were entitled immediately prior to
such event shall be adjusted by multiplying such number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such
event.

               (B) Except as otherwise provided herein or by law, the
holders of shares of Series A Junior Participating 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) (i) If at any time dividends on any Series A
        Junior Participating Preferred Stock shall be in arrears in an
        amount equal to six (6) quarterly dividends thereon, the occurrence
        of such contingency shall mark the beginning of a period (herein
        called a "default period") which shall extend until such time when
        all accrued and unpaid dividends for all previous quarterly
        dividend periods and for the current quarterly dividend period on
        all shares of Series A Junior Participating Preferred Stock then
        outstanding shall have been declared and paid or set apart for
        payment. During each default period, all holders of Preferred Stock
        (including holders of the Series A Junior Participating Preferred
        Stock) with dividends in arrears in an amount equal to six (6)
        quarterly dividends thereon, voting as a class, irrespective of
        series, shall have the right to elect two (2) directors.

                      (ii) During any default period, such voting right of
        the holders of Series A Junior Participating Preferred Stock may be
        exercised initially at a special meeting called pursuant to
        subparagraph (iii) of this Section 3(C) or at any annual meeting of
        stockholders, and thereafter at annual meetings of stockholders,
        provided that neither such voting right nor the right of the
        holders of any other series of Preferred Stock, if any, to
        increase, in certain cases, the authorized number of directors
        shall be exercised unless the holders of ten percent (10%) in
        number of shares of Preferred Stock outstanding shall be present in
        person or by proxy. The absence of a quorum of the holders of
        Common Stock shall not affect the exercise by the holders of
        Preferred Stock of such voting right. At any meeting at which the
        holders of Preferred Stock shall exercise such voting right
        initially during an existing default period, they shall have the
        right, voting as a class, to elect directors to fill such
        vacancies, if any, in the Board of Directors as may then exist up
        to two (2) directors or, if such right is exercised at an annual
        meeting, to elect two (2) directors. If the number which may be so
        elected at any special meeting does not amount to the required
        number, the holders of the Preferred Stock shall have the right to
        make such increase in the number of directors as shall be necessary
        to permit the election by them of the required number. After the
        holders of the Preferred Stock shall have exercised their right to
        elect directors in any default period and during the continuance of
        such period, the number of directors shall not be increased or
        decreased except by vote of the holders of Preferred Stock as
        herein provided or pursuant to the rights of any equity securities
        ranking senior to or pari passu with the Series A Junior Participating
        Preferred Stock.

                      (iii) Unless the holders of Preferred Stock shall,
        during an existing default period, have previously exercised their
        right to elect directors, the Board of Directors may order, or any
        stockholder or stockholders owning in the aggregate not less than
        ten percent (10%) of the total number of shares of Preferred Stock
        outstanding, irrespective of series, may request, the calling of a
        special meeting of the holders of Preferred Stock, which meeting
        shall thereupon be called by the President, a Vice-President or the
        Secretary of the Corporation. Notice of such meeting and of any
        annual meeting at which holders of Preferred Stock are entitled to
        vote pursuant to this Paragraph (C)(iii) shall be given to each
        holder of record of Preferred Stock by mailing a copy of such
        notice to him at his last address as the same appears on the books
        of the Corporation. Such meeting shall be called for a time not
        earlier than 20 days and not later than 60 days after such order or
        request or in default of the calling of such meeting within 60 days
        after such order or request, such meeting may be called on similar
        notice by any stockholder or stockholders owning in the aggregate
        not less than ten percent (10%) of the total number of shares of
        Preferred Stock outstanding. Notwithstanding the provisions of this
        Paragraph (C)(iii), no such special meeting shall be called during
        the period within 60 days immediately preceding the date fixed for
        the next annual meeting of the stockholders.

                      (iv) In any default period, the holders of Common
        Stock, and other classes of stock of the Corporation if applicable,
        shall continue to be entitled to elect the whole number of
        directors until the holders of Preferred Stock shall have exercised
        their right to elect two (2) directors voting as a class, after the
        exercise of which right (x) the directors so elected by the holders
        of Preferred Stock shall continue in office until their successors
        shall have been elected by such holders or until the expiration of
        the default period, and (y) any vacancy in the Board of Directors
        may (except as provided in Paragraph (C)(ii) of this Section 3) be
        filled by vote of a majority of the remaining directors theretofore
        elected by the holders of the class of stock which elected the
        director whose office shall have become vacant. References in this
        Paragraph (C) to directors elected by the holders of a particular
        class of stock shall include directors elected by such directors to
        fill vacancies as provided in clause (y) of the foregoing sentence.

                      (v) Immediately upon the expiration of a default
        period, (x) the right of the holders of Preferred Stock as a class
        to elect directors shall cease, (y) the term of any directors
        elected by the holders of Preferred Stock as a class shall
        terminate, and (z) the number of directors shall be such number as
        may be provided for in the Amended and Restated Certificate of
        Incorporation or Bylaws irrespective of any increase made pursuant
        to the provisions of Paragraph (C)(ii) of this Section 3 (such
        number being subject, however, to change thereafter in any manner
        provided by law or in the certificate of incorporation or by-laws).
        Any vacancies in the Board of Directors effected by the provisions
        of clauses (y) and (z) in the preceding sentence may be filled by a
        majority of the remaining directors.

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

               Section 4. Certain Restrictions.

               (A) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Junior Participating 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 Junior Participating Preferred Stock outstanding shall have
been paid in full, the Corporation shall not

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

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

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

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

               Section 5. Reacquired Shares. Any shares of Series A Junior
Participating Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and cancelled
promptly after the acquisition thereof. All such shares shall upon their
cancellation become authorized but unissued shares of Preferred Stock and
may be reissued as part of a new series of Preferred Stock to be created by
resolution or resolutions of the Board of Directors, subject to the
conditions and restrictions on issuance set forth herein.

               Section 6. Liquidation, Dissolution or Winding Up. (A) Upon
any liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of
stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred
Stock unless, prior thereto, the holders of shares of Series A Junior
Participating Preferred Stock shall have received an amount equal to one
thousand times the purchase price per share of Series A Participating
Preferred Stock, plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such payment
(the "Series A Liquidation Preference"). Following the payment of the full
amount of the Series A Liquidation Preference, no additional distributions
shall be made to the holders of shares of Series A Junior Participating
Preferred Stock unless, prior thereto, the holders of shares of Common
Stock shall have received an amount per share (the "Common Adjustment")
equal to the quotient obtained by dividing (i) the Series A Liquidation
Preference by (ii) 1000 (as appropriately adjusted as set forth in
subparagraph (C) below to reflect such events as stock splits, stock
dividends and recapitalizations with respect to the Common Stock) (such
number in clause (ii), the "Adjustment Number"). Following the payment of
the full amount of the Series A Liquidation Preference and the Common
Adjustment in respect of all outstanding shares of Series A Junior
Participating Preferred Stock and Common Stock, respectively, holders of
Series A Junior Participating Preferred Stock and holders of shares of
Common Stock shall receive their ratable and proportionate share of the
remaining assets to be distributed in the ratio of the Adjustment Number to
1 with respect to such Preferred Stock and Common Stock, on a per share
basis, respectively.

               (B) In the event, however, that there are not sufficient
assets available to permit payment in full of the Series A Liquidation
Preference and the liquidation preferences of all other series of preferred
stock, if any, which rank on a parity with the Series A Junior
Participating Preferred Stock, then such remaining assets shall be
distributed ratably to the holders of such parity shares in proportion to
their respective liquidation preferences. In the event, however, that there
are not sufficient assets available to permit payment in full of the Common
Adjustment, then such remaining assets shall be distributed ratably to the
holders of Common Stock.

               (C) 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 Adjustment Number in effect immediately prior to
such event shall be adjusted by multiplying such Adjustment 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.

               Section 7. 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 Junior Participating 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 1000 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 Junior Participating Preferred Stock shall be
adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

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

               Section 9. Ranking. The Series A Junior Participating
Preferred Stock shall rank junior to all other series of the Corporation's
Preferred Stock as to the payment of dividends and the distribution of
assets, unless the terms of any such series shall provide otherwise.

               Section 10. Amendment. At any time when any shares of Series
A Junior Participating Preferred Stock are outstanding, neither the Amended
and Restated Certificate of Incorporation of the Corporation nor this
Certificate of Designation shall be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series A Junior Participating Preferred Stock so as to affect them
adversely without the affirmative vote of the holders of 66-2/3% or more of
the outstanding shares of Series A Junior Participating Preferred Stock,
voting separately as a class.

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


               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 August, 2000.

                             Rights Certificate

                              Phone.com, Inc.


               This certifies that               , or registered assigns, is
the registered owner of the number of Rights set forth above, each of which
entitles the owner thereof, subject to the terms, provisions and conditions
of the Rights Agreement, dated as of August 8, 2000 (the "Rights
Agreement"), between Phone.com, a Delaware corporation (the "Company"), and
U.S. Stock Transfer Corporation, a California corporation (the "Rights
Agent"), to purchase from the Company at any time prior to 5:00 P.M.
(Redwood City, California time) on August 18, 2010 (unless such date is
extended prior thereto by the Board of Directors) at the office or offices
of the Rights Agent designated for such purpose, or its successors as
Rights Agent, one one-thousandth of a fully paid, non-assessable share of
Series A Junior Participating Preferred Stock (the "Preferred Stock") of
the Company, at a purchase price of $500 per one one-thousandth of a share
(the "Purchase Price"), upon presentation and surrender of this Rights
Certificate with the Form of Election to Purchase and related Certificate
duly executed. The number of Rights evidenced by this Rights Certificate
(and the number of shares which may be purchased upon exercise thereof) set
forth above, and the Purchase Price per share set forth above, are the
number and Purchase Price as of August 18, 2000, based on the Preferred
Stock as constituted at such date. The Company reserves the right to
require prior to the occurrence of a Triggering Event (as such term is
defined in the Rights Agreement) that a number of Rights be exercised so
that only whole shares of Preferred Stock will be issued.

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

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

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

               This Rights Certificate, with or without other Rights
Certificates, upon surrender at the principal office or offices of the
Rights Agent designated for such purpose, may be exchanged for another
Rights Certificate or Rights Certificates of like tenor and date evidencing
Rights entitling the holder to purchase a like aggregate number of one
one-thousandths of a share of Preferred Stock as the Rights evidenced by
the Rights Certificate or Rights Certificates surrendered shall have
entitled such holder to purchase. If this Rights Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender
hereof another Rights Certificate or Rights Certificates for the number of
whole Rights not exercised.

               Subject to the provisions of the Rights Agreement, the
Rights evidenced by this Certificate may be redeemed by the Company at its
option at a redemption price of $.001 per Right at any time prior to the
earlier of the close of business on (i) the tenth Business Day following
the Stock Acquisition Date (as such time period may be extended pursuant to
the Rights Agreement), and (ii) the Final Expiration Date. In addition,
under certain circumstances following the Stock Acquisition Date, the
Rights may be exchanged, in whole or in part, for shares of the Common
Stock, or shares of preferred stock of the Company having essentially the
same value or economic rights as such shares. Immediately upon the action
of the Board of Directors of the Company authorizing any such exchange, and
without any further action or any notice, the Rights (other than Rights
which are not subject to such exchange) will terminate and the Rights will
only enable holders to receive the shares issuable upon such exchange.

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

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

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


               WITNESS the facsimile signature of the proper officers of
the Company and its corporate seal.

                       SUMMARY OF RIGHTS TO PURCHASE
                              PREFERRED STOCK


               On August 8, 2000, the Board of Directors of Phone.com, Inc.
(the "Company") declared a dividend distribution of one Right for each
outstanding share of Company Common Stock to stockholders of record at the
close of business on August 18, 2000 (the "Record Date"). Each Right
entitles the registered holder to purchase from the Company a unit
consisting of one one-thousandth of a share (a "Unit") of Series A Junior
Participating Preferred Stock, par value $.001 per share (the "Series A
Preferred Stock") at a Purchase Price of five hundred dollars ($500) per
Unit, subject to adjustment. The description and terms of the Rights are
set forth in a Rights Agreement (the "Rights Agreement") between the
Company and U.S. Stock Transfer Corporation, as Rights Agent.

               Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
Certificates will be distributed. Subject to certain exceptions specified
in the Rights Agreement including the consummation of the transactions
contemplated by the combination of the Company and Software.com, Inc., the
Rights will separate from the Common Stock and a Distribution Date will
occur upon the earlier of (i) 10 business days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired beneficial ownership of 15% or more of the
outstanding shares of Common Stock (the "Stock Acquisition Date"); or (ii)
10 business days (or such later date as the Board shall determine)
following the commencement of a tender offer or exchange offer that would
result in a person or group becoming an Acquiring Person. Until the
Distribution Date, (i) the Rights will be evidenced by the Common Stock
certificates and will be transferred with and only with such Common Stock
certificates, (ii) new Common Stock certificates issued after the Record
Date will contain a notation incorporating the Rights Agreement by
reference and (iii) the surrender for transfer of any certificates for
Common Stock outstanding will also constitute the transfer of the Rights
associated with the Common Stock represented by such certificate. Pursuant
to the Rights Agreement, the Company reserves the right to require prior to
the occurrence of a Triggering Event (as defined below) that, upon any
exercise of Rights, a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

               The Rights are not exercisable until the Distribution Date
and will expire at 5:00 P.M. (Redwood City, California time) on August 18,
2010, unless such date is extended or the Rights are earlier redeemed or
exchanged by the Company as described below.

               As soon as practicable after the Distribution Date, Rights
Certificates will be mailed to holders of record of the Common Stock as of
the close of business on the Distribution Date and, thereafter, the
separate Rights Certificates alone will represent the Rights. Except as
otherwise determined by the Board of Directors, only shares of Common Stock
issued prior to the Distribution Date will be issued with Rights.

               In the event that a Person becomes an Acquiring Person,
except pursuant to an offer for all outstanding shares of Common Stock
which the independent directors determine to be fair and not inadequate to
and to otherwise be in the best interests of the Company and its
stockholders, after receiving advice from one or more investment banking
firms (a "Qualified Offer"), each holder of a Right will thereafter have
the right to receive, upon exercise, Common Stock (or, in certain
circumstances, cash, property or other securities of the Company) having a
value equal to two times the exercise price of the Right. Notwithstanding
any of the foregoing, following the occurrence of the event set forth in
this paragraph, all Rights that are, or (under certain circumstances
specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person will be null and void. However, Rights are not exercisable
following the occurrence of the event set forth above until such time as
the Rights are no longer redeemable by the Company as set forth below.

               For example, at an exercise price of five hundred dollars
($500) per Right, each Right not owned by an Acquiring Person (or by
certain related parties) following an event set forth in the preceding
paragraph would entitle its holder to purchase $1000 worth of Common Stock
(or other consideration, as noted above) for $500. Assuming that the Common
Stock had a per share value of $100 at such time, the holder of each valid
Right would be entitled to purchase 10 shares of Common Stock for $500.

               In the event that, at any time following the Stock
Acquisition Date, (i) the Company engages in a merger or other business
combination transaction in which the Company is not the surviving
corporation (other than with an entity which acquired the shares pursuant
to a Qualified Offer), (ii) the Company engages in a merger or other
business combination transaction in which the Company is the surviving
corporation and the Common Stock of the Company is changed or exchanged, or
(iii) 50% or more of the Company's assets, cash flow or earning power is
sold or transferred, each holder of a Right (except Rights which have
previously been voided as set forth above) shall thereafter have the right
to receive, upon exercise, common stock of the acquiring company having a
value equal to two times the exercise price of the Right. The events set
forth in this paragraph and in the second preceding paragraph are referred
to as the "Triggering Events."

               At any time after a person becomes an Acquiring Person and
prior to the acquisition by such person or group of fifty percent (50%) or
more of the outstanding Common Stock, the Board may exchange the Rights
(other than Rights owned by such person or group which have become void),
in whole or in part, at an exchange ratio of one share of Common Stock, or
one one-thousandth of a share of Preferred Stock (or of a share of a class
or series of the Company's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

               At any time until ten business days following the Stock
Acquisition Date, the Company may redeem the Rights in whole, but not in
part, at a price of $.001 per Right (payable in cash, Common Stock or other
consideration deemed appropriate by the Board of Directors). Immediately
upon the action of the Board of Directors ordering redemption of the
Rights, the Rights will terminate and the only right of the holders of
Rights will be to receive the $.001 redemption price.

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

               Any of the provisions of the Rights Agreement may be amended
by the Board of Directors of the Company prior to the Distribution Date.
After the Distribution Date, the provisions of the Rights Agreement may be
amended by the Board in order to cure any ambiguity, to make changes which
do not adversely affect the interests of holders of Rights, or to shorten
or lengthen any time period under the Rights Agreement. The foregoing
notwithstanding, no amendment may be made at such time as the Rights are
not redeemable.

               A copy of the Rights Agreement is being filed with the
Securities and Exchange Commission as an Exhibit to a Registration
Statement on Form 8-A/Current Report on Form 8-K dated [____], 2000. A copy
of the Rights Agreement is available free of charge from the Rights Agent.
This summary description of the Rights does not purport to be complete and
is qualified in its entirety by reference to the Rights Agreement, which is
incorporated herein by reference.
