ITEM 1.   DESCRIPTION OF SECURITIES TO BE REGISTERED.

     On November 24, 1998 pursuant to a Preferred Shares Rights Agreement (the
"Rights Agreement") between CellNet Data Systems, Inc. (the "Company") and The
Bank of New York, as Rights Agent (the "Rights Agent"), the Company's Board of
Directors declared a dividend of one right (a "Right") to purchase one
one-thousandth share of the Company's Series A Participating Preferred Stock,
$0.001 par value per share ("Series A Preferred") for each outstanding share of
Common Stock, $0.001 par value per share ("Common Stock"), of the Company.  The
dividend is payable on December 21, 1998 (the "Record Date") to stockholders of
record as of the close of business on that date.  Each Right entitles the
registered holder to purchase from the Company one one-thousandth of a share of
Series A Preferred at an exercise price of $50.00 (the "Purchase Price"),
subject to adjustment.

     The following summary of the principal terms of the Rights Agreement is a
general description only and is subject to the detailed terms and conditions of
the Rights Agreement. A copy of the Rights Agreement is attached as Exhibit 1 to
this Registration Statement and is incorporated herein by reference.

RIGHTS EVIDENCED BY COMMON STOCK CERTIFICATES

     The Rights will not be exercisable until the Distribution Date (defined
below). Certificates for the Rights ("Rights Certificates") will not be sent to
stockholders initially and the Rights will attach to and trade only together
with the Common Stock.  Accordingly, Common Stock certificates outstanding on
the Record Date will evidence the Rights related thereto, and Common Stock
certificates issued after the Record Date will contain a notation incorporating
the Rights Agreement by reference. Until the Distribution Date (or earlier
redemption or expiration of the Rights), the surrender or transfer of any
certificates for Common Stock outstanding as of the Record Date  will also
constitute the transfer of the Rights associated with the Common Stock
represented by such certificate.

DISTRIBUTION DATE

     The Rights will separate from the Common Stock, Rights Certificates will be
issued and the Rights will become exercisable upon the earlier of:  (i) the
close of business on the 10th day (or such later date as may be determined by a
majority of the Board of Directors) 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 Common Stock, or
(ii) the close of business on the 10th business day (or such later date as may
be determined by a majority of the Board of Directors) following the date that a
tender or exchange offer is announced or made, the consummation of which would
result in the beneficial ownership by a person or group of 15% or more of the
outstanding Common Stock. The earlier of such dates is referred to as the
"Distribution Date."

ISSUANCE OF RIGHTS CERTIFICATES; EXPIRATION OF RIGHTS

     As soon as practicable following the Distribution Date, separate Rights 
Certificates will be mailed to holders of record of the Common Stock as of 
the close of business on the Distribution Date and such separate Rights 
Certificates alone will evidence the Rights from and after the Distribution 
Date.  All Common Stock issued prior to the Distribution Date will be issued 
with Rights.  Common Stock issued after the Distribution Date (i) will be 
issued with Rights if such Common Stock is issued or sold (a) in connection 
with the exercise of any stock option, (b) under any employee benefit plan, 
(c) upon the exchange of Funding Preferred Securities (as defined in the 
Rights Agreement), (d) upon a Warrant Exchange (as defined in the Rights 
Agreement), or (e) upon the exercise, conversion or exchange of other 
securities of the Company, and (ii) may be issued with such Rights in any 
other case if deemed necessary or appropriate by the Board of Directors 
unless and to the extent that, in each case, such issuance would create a 
significant risk of or result in material adverse tax consequences to the 
Company or to the person to whom such Rights Certificate would be issued or 
would create a significant risk of or result in such options' or employee 
plans' or arrangements' failing 

                                  -2-
<PAGE>


to qualify for otherwise available special tax treatment.  The Rights expire 
on the earliest of (a) November 24, 2008 (the "Final Expiration Date'),  (b) 
the consummation of any of the following transactions (i) the Company merges 
into another entity, (ii) an acquiring entity merges into the Company, or 
(iii) the Company sells more than fifty percent (50%) of its assets or 
earning power, (c) the effective date of a redemption of the Rights 
determined by the Board of Directors, and (d) the time at which the Board of 
Directors orders an exchange of the Rights.

INITIAL EXERCISE OF THE RIGHTS

     Following the Distribution Date, and until one of the additional events
described below, holders of the Rights will be entitled to receive, upon
exercise and payment of the Purchase Price per Right, one one-thousandth of a
share of the Series A Preferred.  In the event that the Company does not have
sufficient shares of Common Stock available for all Rights to be exercised, or
the Board decides that such action is necessary and not contrary to the
interests of Rights holders, the Company may instead substitute cash, assets or
other securities for the shares of Common Stock issuable upon exercise of such
Rights.

RIGHT TO BUY COMPANY COMMON STOCK

     Unless the Rights are earlier redeemed or have expired, in the event that
an Acquiring Person becomes the beneficial owner of 15% or more of the Company's
Common Stock then outstanding, then proper provision will be made so that each
holder of a Right which has not theretofore been exercised (other than Rights
beneficially owned by the Acquiring Person, which will thereafter be void) will
thereafter have the right to receive, upon exercise, Common Stock having a value
equal to two times the Purchase Price.  Rights are not exercisable following the
occurrence of an event as described above until such time as the Rights are no
longer redeemable by the Company as set forth below.

RIGHT TO BUY ACQUIRING COMPANY STOCK

     Similarly, unless the Rights are earlier redeemed or have expired, in the
event that, after the Stock Acquisition Date (as defined below), (i) the Company
merges into another entity, (ii) an acquiring entity merges into the Company, or
(iii) the Company sells more than fifty percent (50%) of its assets or earning
power, then each holder of a Right which has not theretofore been exercised
(other than Rights beneficially owned by the Acquiring Person, which will
thereafter be void) will thereafter have the right to receive, upon exercise,
shares of common stock of the acquiring company having a value equal to two
times the Purchase Price (unless the transaction satisfies certain conditions
and is consummated with a person who acquired shares pursuant to a Permitted
Offer, in which case the Rights will expire).

EXCHANGE PROVISION

     At any time after the acquisition by a Person of 15% or more of the
Company's outstanding Common Stock and prior to the acquisition by such Person
of 50% or more of the Company's outstanding Common Stock, the Board of Directors
of the Company may exchange the Rights (other than Rights owned by the Acquiring
Person), in whole or in part, at an exchange ratio of one Common Share per
Right, subject to adjustment.

REDEMPTION

     At any time prior to the close of business on the earlier of (i) the first
date of public announcement by the Company or an Acquiring Person that an
Acquiring Person has become such (the "Share Acquisition Date") or (ii) the
Final Expiration Date of the Rights, the Company may redeem the Rights in whole,
but not in part, at a price of $0.001 per Right, subject to adjustment, payable
in cash or in shares of the Company's Common Stock.


                                      -3-
<PAGE>


ADJUSTMENTS TO PREVENT DILUTION

     The Purchase Price payable, the number of Rights, and the number of Series
A Preferred, Common Stock,  or other securities or property issuable upon
exercise of the Rights are subject to adjustment from time to time in connection
with the dilutive issuances by the Company as set forth in the Rights Agreement.
With certain exceptions, no adjustment in the Purchase Price will be required
until cumulative adjustments require an adjustment of at least 1% in such
Purchase Price.

CASH PAID INSTEAD OF ISSUING FRACTIONAL STOCK

     No fractional portion less than integral multiples of one Common Share will
be issued upon exercise of a Right and in lieu thereof, an adjustment in cash
will be made based on the market price of the Common Stock on the last trading
date prior to the date of exercise.

NO STOCKHOLDERS' RIGHTS PRIOR TO EXERCISE

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company (other than any rights resulting from
such holder's ownership of Common Stock), including, without limitation, the
right to vote or to receive dividends.

AMENDMENT OF RIGHTS AGREEMENT

     The provisions of the Rights Agreement may be supplemented or amended by
the Board of Directors in any manner prior to the date a person becomes an
Acquiring Person without the approval of Rights holders.  After the Distribution
Date, the provisions of the Rights Agreement may be amended by the Board in
order to (i) cure any ambiguity, (ii) correct or supplement any provision
contained therein which may be defective or inconsistent with any other
provisions therein, (iii) shorten or lengthen any time period thereunder, or
(iv) to change or supplement the provisions thereunder in any manner that the
Company may deem necessary or desirable and that shall not adversely affect the
interests of the holders of Rights (other than an Acquiring Person or an
affiliate or associate of an Acquiring Person); provided, however, that no
amendment to lengthen the time period governing redemption shall be made at such
time as the Rights are not redeemable or at any other time unless such
lengthening is for the purpose of protecting, enhancing or clarifying the rights
of, and/or the benefits to, the holders of Rights (other than an Acquiring
Person or an affiliate or associate of an Acquiring Person). 

RIGHTS AND PREFERENCES OF THE SERIES A PREFERRED

     Series A Preferred purchasable upon exercise of the Rights will not be
redeemable.  Each share of Series A Preferred will be entitled to an aggregate
dividend of 1,000 times the dividend declared per Common Share.  In the event of
liquidation, the holders of the Series A Preferred will be entitled to a minimum
preferential liquidation payment equal to 1,000 times the per share amount to be
distributed to the holders of the Common Stock plus an amount equal to any
accrued and unpaid dividends on such shares of Series A Preferred Stock.  Each
share of Series A Preferred will have 1,000 votes, voting together with the
Common Stock.  In the event of any merger, consolidation or other transaction in
which the Common Stock are changed or exchanged, each share of Series A
Preferred will be entitled to receive 1,000 times the amount received per Common
Share.  These rights are protected by customary anti-dilution provisions.

     Because of the nature of the dividend, liquidation and voting rights of the
shares of Series A Preferred, the value of the one one-thousandth interest in a
share of Series A Preferred purchasable upon exercise of each Right should
approximate the value of one Common Share.


                                      -4-
<PAGE>


CERTAIN ANTI-TAKEOVER EFFECTS

     The Rights approved by the Board are designed to protect and maximize the
value of the outstanding equity interests in the Company in the event of an
unsolicited attempt by an acquiror to take over the Company, in a manner or on
terms not approved by the Board of Directors.  Takeover attempts frequently
include coercive tactics to deprive the Company's Board of Directors and its
stockholders of any real opportunity to determine the destiny of the Company.
The Rights have been declared by the Board in order to deter such tactics,
including a gradual accumulation of shares in the open market of a 15% or
greater position to be followed by a merger or a partial or two-tier tender
offer that does not treat all stockholders equally.  These tactics unfairly
pressure stockholders, squeeze them out of their investment without giving them
any real choice and deprive them of the full value of their shares.

     The Rights are not intended to prevent a takeover of the Company and will
not do so.  Because the Rights may be redeemed by the Company at $0.001 per
Right on the earlier of the Share Acquisition Date or the Final Expiration Date
of the Rights, the Rights should not interfere with any merger or business
combination approved by the Board of Directors.

     Issuance of the Rights does not in any way weaken the financial strength of
the Company or interfere with its business plans.  The issuance of the Rights
themselves has no dilutive effect, will not affect reported earnings per share,
should not be taxable to the Company or to its stockholders, and will not change
the way in which the Company's shares are presently traded.  The Company's Board
of Directors believes that the Rights represent a sound and reasonable means of
addressing the complex issues of corporate policy created by the current
takeover environment.

     However, the Rights may have the effect of rendering more difficult or
discouraging an acquisition of the Company deemed undesirable by the Board of
Directors.  The Rights may cause substantial dilution to a person or group that
attempts to acquire the Company on terms or in a manner not approved by the
Company's Board of Directors, except pursuant to an offer conditioned upon the
negation, purchase or redemption of the Rights.

                                 RIGHTS AGREEMENT


         Agreement, dated as of November 24, 1998, between CellNet Data Systems,
Inc., a Delaware corporation (the "COMPANY"), and The Bank of New York.

         On November 24, 1998 (the "RIGHTS DIVIDEND DECLARATION DATE"), the
Board of Directors of the Company authorized and declared a dividend of one
Preferred Share Purchase Right (a "RIGHT") for each Common Share (as hereinafter
defined) of the Company outstanding as of the Close of Business (as hereinafter
defined) on December 21, 1998 (the "RECORD DATE"), each Right representing the
right to purchase one one-thousandth of a share of Series A Participating
Preferred Stock (as such number may be adjusted pursuant to the provisions of
this Agreement), having the rights, preferences and privileges set forth in the
form of Certificate of Designation of Rights, Preferences and Privileges of
Series A Participating Preferred Stock attached hereto as EXHIBIT A, upon the
terms and subject to the conditions herein set forth, and further authorized and
directed the issuance of one Right (as such number may be adjusted pursuant to
the provisions of this Agreement) with respect to each Common Share that shall
become outstanding between the Record Date and the earlier of the Distribution
Date and the Expiration Date (as such terms are hereinafter defined), and in
certain circumstances after the Distribution Date.

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

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

                  (a) "ACQUIRING PERSON" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the Common Shares then outstanding, but shall
not include the Company, any Subsidiary of the Company or any employee benefit
plan of the Company or of any Subsidiary of the Company, or any entity holding
Common Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall be deemed to be an Acquiring Person as the result of
an acquisition of Common Shares by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to 15% or more of the Common Shares of the Company then
outstanding; PROVIDED, HOWEVER, that if a Person shall become the Beneficial
Owner of 15% or more of the Common Shares of the Company then outstanding by
reason of share purchases by the Company and shall, after such share purchases
by the Company, become the Beneficial Owner of any additional Common Shares of
the Company (other than pursuant to a dividend or distribution paid or made by
the Company on the outstanding Common Shares in Common Shares or pursuant to a
split or subdivision of the outstanding Common Shares), then such Person shall
be deemed to be an Acquiring Person unless upon becoming the Beneficial Owner of
such additional Common Shares of the Company such Person does not beneficially
own 15% or more of the Common Shares of the Company then outstanding.
Notwithstanding the foregoing, (i) if the Company's Board of Directors
determines in good faith that a Person who would otherwise be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this paragraph (a),
has become such inadvertently (including, without limitation, because (A) such
Person was unaware that it beneficially owned a percentage of the Common Shares
that would otherwise 

                                      
<PAGE>

cause such Person to be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), or (B) such Person was aware of the
extent of the Common Shares it beneficially owned but had no actual knowledge of
the consequences of such beneficial ownership under this Agreement) and without
any intention of changing or influencing control of the Company, and if such
Person divested or divests as promptly as practicable a sufficient number of
Common Shares so that such Person would no longer be an "Acquiring Person," as
defined pursuant to the foregoing provisions of this paragraph (a), then such
Person shall not be deemed to be or to have become an "Acquiring Person" for any
purposes of this Agreement; and (ii) if, as of the date hereof, any Person is
the Beneficial Owner of 15% or more of the Common Shares outstanding, such
Person shall not be or become an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), unless and until such time as such
Person shall become the Beneficial Owner of additional Common Shares (other than
pursuant to a dividend or distribution paid or made by the Company on the
outstanding Common Shares in Common Shares or pursuant to a split or subdivision
of the outstanding Common Shares), unless, upon becoming the Beneficial Owner of
such additional Common Shares, such Person is not then the Beneficial Owner of
15% or more of the Common Shares then outstanding.

                  (b) "ADJUSTMENT FRACTION" shall have the meaning set forth in
Section 11(a)(i) hereof.

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

                  (d) A Person shall be deemed the "BENEFICIAL OWNER" of and
shall be deemed to "BENEFICIALLY OWN" any securities:

                         (i) which such Person or any of such Person's 
          Affiliates or Associates beneficially owns, directly or indirectly, 
          for purposes of Section 13(d) of the Exchange Act and Rule 13d-3 
          thereunder (or any comparable or successor law or regulation);

                        (ii) which such Person or any of such Person's 
          Affiliates or Associates has (A) the right to acquire (whether such 
          right is exercisable immediately or only after the passage of time) 
          pursuant to any agreement, arrangement or understanding (other than 
          customary agreements with and between underwriters and selling group 
          members with respect to a bona fide public offering of securities), 
          or upon the exercise of conversion rights, exchange rights, rights 
          (other than the Rights), warrants or options, or otherwise; PROVIDED,
          HOWEVER, that a Person shall not be deemed pursuant to this Section 
          1(d)(ii)(A) to be the Beneficial Owner of, or to beneficially own, (1)
          securities tendered pursuant to a tender or exchange offer made by or
          on behalf of such Person or any of such Person's Affiliates or 
          Associates until such tendered securities are accepted for purchase or
          exchange, or (2) securities which a Person or any of such Person's 
          Affiliates or Associates may be deemed to have the right to acquire 
          pursuant to any merger or other acquisition agreement between the 
          Company and such Person (or one or more of its Affiliates or 
          Associates) if such agreement has been approved by the Board of 
          Directors 

                                      -2-

          of the Company prior to there being an Acquiring Person; or (B) the 
          right to vote pursuant to any agreement, arrangement or understanding;
          PROVIDED, HOWEVER, that a Person shall not be deemed the Beneficial 
          Owner of, or to beneficially own, any security under this Section 
          1(d)(ii)(B) if the agreement, arrangement or understanding to vote 
          such security (1) arises solely from a revocable proxy or consent 
          given to such Person in response to a public proxy or consent 
          solicitation made pursuant to, and in accordance with, the applicable
          rules and regulations of the Exchange Act and (2) is not also then

          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 (other than customary agreements with and between 
          underwriters and selling group members with respect to a bona fide 
          public offering of securities) for the purpose of acquiring, holding,
          voting (except to the extent contemplated by the proviso to Section 
          1(d)(ii)(B)) or disposing of any securities of the Company; PROVIDED,
          HOWEVER, that in no case shall an officer or director of the Company 
          be deemed (x) the Beneficial Owner of any securities beneficially 
          owned by another officer or director of the Company solely by reason 
          of actions undertaken by such persons in their capacity as officers or
          directors of the Company or (y) the Beneficial Owner of securities 
          held of record by the trustee of any employee benefit plan of the 
          Company or any Subsidiary of the Company for the benefit of any 
          employee of the Company or any Subsidiary of the Company, other than 
          the officer or director, by reason of any influence that such officer

daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days immediately prior to such date, and for purposes of computations

closing prices per share of such Security for the ten (10) consecutive Trading
Days immediately prior to such date; PROVIDED, HOWEVER, that in the event that
the Current Per Share Market Price of the Security is determined during a period
following the announcement by the issuer of such Security of (i) a dividend or
distribution on such Security payable in shares of such Security or securities
convertible into such shares or (ii) any subdivision, combination or
reclassification of such Security, and prior to the expiration of the applicable
thirty (30) Trading Day or ten (10) Trading Day period, after the ex-dividend
date for such dividend or distribution, or the record date for such subdivision,
combination or reclassification, then, and in each such case, the Current Per
Share Market Price shall be appropriately adjusted to reflect the current market

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

New York Stock Exchange, as reported in the principal consolidated transaction

Company shall be used. If the Preferred Shares are not publicly traded, the
Current Per Share Market Price of the Preferred Shares shall be conclusively
deemed to be the Current Per Share Market Price of the Common Shares as
determined pursuant to this Section 1(j), as appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof, multiplied by 1000. If the Security is not publicly held or so listed or
traded, Current Per Share Market Price shall mean the fair value per share as
determined in good faith by the Board of Directors of the Company, whose

         Section 3.  ISSUANCE OF RIGHTS CERTIFICATES.

                  (a) Until the Distribution Date, (i) the Rights will be 
evidenced (subject to the provisions of Sections 3(b), 3(c) and 3(d) hereof) 
by the certificates for Common Shares registered in the names of the holders 
thereof (which certificates shall also be deemed to be Rights Certificates) 
and not by separate Rights Certificates and (ii) the right to receive Rights 
Certificates will be transferable only in connection with the transfer of 
Common Shares. Until the earlier of the Distribution Date or the Expiration 
Date, the surrender for transfer of such certificates for Common Shares shall 
also constitute the surrender for transfer of the Rights associated with the 
Common Shares represented thereby. As soon as practicable after the 
Distribution Date, the Company will prepare and execute, the Rights Agent

Rights Agent will, if requested, send) by first-class, postage-prepaid mail, 
to each record holder of Common Shares as of the Close of Business on the 
Distribution Date, at the address of such holder shown on the records of the 
Company, a Rights Certificate evidencing one Right for each Common Share so

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 the Distribution Date, 
the Rights will be evidenced solely by such Rights Certificates and may be 
transferred by the transfer of the Rights Certificates as permitted hereby, 
separately and apart from any transfer of Common Shares, and the holders of 
such Rights Certificates as listed in the records of the Company or any 
transfer agent or registrar for the Rights shall be the record holders 
thereof.

                  (b) On the Record Date or as soon as practicable thereafter,
the Company will send a copy of the Summary of Rights by first-class, postage-
prepaid mail, to each record holder of Common Shares as of the Close of
Business on the Record Date, at the address of such holder shown on the 

                                      -7-
<PAGE>

records of the Company's transfer agent and registrar. With respect to 
certificates for Common Shares outstanding as of the Record Date, until the 
Distribution Date, the Rights will be evidenced by such certificates 
registered in the names of the holders thereof together with the Summary of 
Rights. Until the Distribution Date (or, if earlier, the Expiration Date), 
the surrender for transfer of any certificate for Common Shares outstanding 
on the Record Date, with or without a copy of the Summary of Rights, shall 
also constitute the transfer of the Rights associated with the Common Shares 
represented thereby.

                  (c) Unless the Board of Directors by resolution adopted at or
before the time of the issuance of any Common Shares specifies to the contrary,
Rights shall be issued in respect of all Common Shares that are issued after the
Record Date but prior to the earlier of the Distribution Date or the Expiration
Date or, in certain circumstances provided in Section 22 hereof, after the
Distribution Date. Certificates representing such Common Shares 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 A RIGHTS AGREEMENT BETWEEN

                  RIGHTS AGENT, DATED AS OF NOVEMBER 24, 1998 AS THE SAME MAY BE
                  AMENDED FROM TIME TO TIME (THE "RIGHTS AGREEMENT"), THE TERMS
                  OF WHICH ARE HEREBY INCORPORATED HEREIN BY REFERENCE AND A
                  COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF
                  CELLNET DATA SYSTEMS, INC. UNDER CERTAIN CIRCUMSTANCES, AS SET
                  FORTH IN THE RIGHTS AGREEMENT, SUCH RIGHTS WILL BE EVIDENCED
                  BY SEPARATE CERTIFICATES AND WILL NO LONGER BE EVIDENCED BY
                  THIS CERTIFICATE. THE BANK OF NEW YORK WILL MAIL TO THE HOLDER
                  OF THIS CERTIFICATE A COPY OF THE RIGHTS AGREEMENT WITHOUT
                  CHARGE 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 Shares represented by such certificates shall be
evidenced by such certificates alone, and the surrender for transfer of any such
certificate shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

                  (d) In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.

         Section 4.  FORM OF RIGHTS CERTIFICATES.

                  (a) The Rights Certificates (and the forms of election to 
purchase Common Shares and of assignment to be printed on the reverse 
thereof) shall be substantially in the form of Exhibit B hereto and may have 
such marks of identification or designation and such legends, summaries or 
endorsements printed thereon as the Company may deem appropriate and as are 
not inconsistent with the provisions of this Agreement, or as may be required 
to comply with any applicable law or with any rule or regulation made 
pursuant thereto or with any rule or regulation of any stock exchange, or a 
national market system or automated quotation system, on which the Rights may 
from time to time be listed or included, 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 (or in the case of 
Rights issued with respect to Common Shares issued by the Company after the 
Record Date, as of the date of issuance of such Common Shares) and on their 
face shall entitle the holders thereof to purchase such number of 
one-thousandths of a Preferred Share as shall be set forth therein at the 
price set forth therein (such exercise price per one one-thousandth of a 
Preferred Share being hereinafter referred to as the "EXERCISE PRICE" and the 
aggregate Exercise Price of all Preferred Shares issuable upon exercise of 
one Right being hereinafter referred to as the "TOTAL EXERCISE PRICE"), but 
the number and type of securities purchasable upon the exercise of each Right 
and the Exercise Price shall be subject to adjustment as provided herein.

                  (b) Any Rights Certificate issued pursuant to Section 3(a) 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 Company's Board of Directors 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 Chief Executive Officer, its 
Chief Financial Officer, its President or any Vice President, either manually 
or by facsimile signature, and by the Secretary or an Assistant Secretary of 
the Company, either manually or by facsimile signature, and shall have 
affixed thereto the Company's seal (if any) or a facsimile thereof. The 
Rights Certificates shall be manually countersigned by the Rights Agent and 
shall not be valid for any purpose unless countersigned. In case any officer 
of the Company who shall have signed any of the 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 on behalf of the Company had not ceased 
to be such officer of the Company; and any Rights Certificate 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 office designated for such purposes, 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 Sections 7(e), 14 and 24 
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 Rights Certificates may be transferred, split up, combined or 
exchanged for another Rights Certificate or Rights Certificates, entitling 
the registered holder to purchase a like number of one-thousandths of a 
Preferred Share (or, following a Triggering Event, other securities, cash or 
other assets, as the case may be) as the Rights Certificate or Rights 
Certificates surrendered then entitled such holder to purchase. Any 
registered holder desiring to transfer, split up, combine or exchange any 
Rights Certificate or Rights Certificates shall make such request in writing 
delivered to the Rights Agent, and shall surrender the Rights Certificate or 
Rights Certificates to be transferred, split up, combined or exchanged at the 
office of the Rights Agent designated for such purpose. Neither the Rights 
Agent nor the Company shall be obligated to take any action whatsoever with 
respect to the transfer of any such surrendered Rights Certificate until the 
registered holder shall have completed and

                                       -10-
<PAGE>

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 Sections 7(e), 14 and 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, 
at the Company's request, reimbursement to the Company and the Rights Agent 
of all reasonable expenses incidental thereto, and upon surrender to the 
Rights Agent and cancellation of the Rights Certificate if mutilated, the 
Company will make and deliver a new Rights Certificate of like tenor to the 
Rights Agent for delivery to the registered holder in lieu of the Rights 
Certificate so lost, stolen, destroyed or mutilated.

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

                  (a) Subject to Sections 7(e), 23(b) and 24(b) hereof, the 
registered holder of any Rights Certificate may exercise the Rights evidenced 
thereby (except as otherwise provided herein) in whole or in part at any time 
after the Distribution Date and prior to the Close of Business on the 
Expiration Date by surrender of the Rights Certificate, with the form of 
election to purchase on the reverse side thereof duly executed, to the Rights 
Agent at the office of the Rights Agent designated for such purpose, together 
with payment of the Exercise Price for each one-thousandth of a Preferred 
Share (or, following a Triggering Event, other securities, cash or other 
assets as the case may be) as to which the Rights are exercised.

                  (b) The Exercise Price for each one-thousandth of a 
Preferred Share issuable pursuant to the exercise of a Right shall initially 
be Fifty Dollars ($50.00), shall be subject to adjustment from time to time 
as provided in Sections 11 and 13 hereof and shall be payable in lawful money 
of the United States of America in accordance with paragraph (c) below.

                  (c) Upon receipt of a Rights Certificate representing 
exercisable Rights, with the form of election to purchase duly executed, 
accompanied by payment of the Exercise Price for the number of 
one-thousandths of a Preferred Share (or, following a Triggering Event, other 
securities, cash or other assets as the case may be) to be purchased and an 
amount equal to any applicable transfer tax required to be paid by the holder 
of such Rights Certificate in accordance with Section 9(e) hereof, the Rights 
Agent shall, subject to Section 20(k) hereof, thereupon promptly (i) (A) 
requisition from any transfer agent of the Preferred Shares (or make 
available, if the Rights Agent is the transfer agent for the Preferred 
Shares) a certificate or certificates for the number of one-thousandths of a 
Preferred Share (or, following a Triggering Event, other securities, cash or 
other assets as the case may be) to be purchased and the Company hereby 
irrevocably authorizes its transfer agent to comply with all such requests or

                                       -11-
<PAGE>

(B) if the Company shall have elected to deposit the total number of 
one-thousandths of a Preferred Share (or, following a Triggering Event, other 
securities, cash or other assets as the case may be) issuable upon exercise 
of the Rights hereunder with a depositary agent, requisition from the 
depositary agent depositary receipts representing such number of 
one-thousandths of a Preferred Share (or, following a Triggering Event, other 
securities, cash or other assets as the case may be) as are to be purchased 
(in which case certificates for the Preferred Shares (or, following a 
Triggering Event, other securities, cash or other assets as the case may be) 
represented by such receipts shall be deposited by the transfer agent with 
the depositary agent) and the Company hereby directs the depositary agent to 
comply with such request, (ii) when appropriate, requisition from the Company 
the amount of cash to be paid in lieu of issuance of fractional shares in 
accordance with Section 14 hereof, (iii) after receipt of such certificates 
or depositary receipts, cause the same to be delivered to or upon the order 
of the registered holder of such Rights Certificate, registered in such name 
or names as may be designated by such holder, and (iv) when appropriate, after 
receipt thereof, deliver such cash to or upon the order of the registered 
holder of such Rights Certificate. The payment of the Exercise Price (as such 
amount may be reduced (including to zero) pursuant to Section 11(a)(iii) 
hereof) and an amount equal to any applicable transfer tax required to be 
paid by the holder of such Rights Certificate in accordance with Section 9(e) 
hereof, may be made in cash or by certified bank check, cashier's check or 
bank draft payable to the order of the Company. In the event that the Company 
is obligated to issue securities of the Company other than Preferred Shares, 
pay cash and/or distribute other property pursuant to Section 11(a) hereof, 
the Company will make all arrangements necessary so that such other 
securities, cash and/or other property are available for distribution by the 
Rights Agent, if and when appropriate.

                  (d) 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 to the registered holder of such Rights 
Certificate or to his or her duly authorized assigns, 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 Triggering 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 (a "POST-EVENT TRANSFEREE"), (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 Company's Board of Directors 
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) (a "PRE-EVENT 
TRANSFEREE"), or (iv) any subsequent transferee receiving transferred Rights 
from a Post-Event Transferee or a Pre-Event Transferee, either directly or 
through one or more intermediate transferees, 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 
ensure that the provisions of this Section 7(e) and

                                       -12-
<PAGE>

Section 4(b) hereof are complied with, but shall have no liability to any 
holder of Rights Certificates or to any other Person as a result of its 
failure to make any determinations with respect to an Acquiring Person or any 
of such Acquiring Person's 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, in addition to having complied with the requirements 
of Section 7(a) above, 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 to any of 
its agents, be delivered to the Rights Agent for cancellation or in canceled 
form, or, if surrendered to the Rights Agent, shall be canceled by it, and no 
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 Rights Certificate purchased or 
acquired by the Company otherwise than upon the exercise thereof. The Rights 
Agent shall deliver all canceled Rights Certificates to the Company, or 
shall, at the written request of the Company, destroy such canceled Rights 
Certificates, and in such case shall deliver a certificate of destruction 
thereof to the Company.

         Section 9.  RESERVATION AND AVAILABILITY OF PREFERRED SHARES.

                  (a) The Company covenants and agrees that it will use its 
best efforts to cause to be reserved and kept available out of its authorized 
and unissued Preferred Shares not reserved for another purpose (and, 
following the occurrence of a Triggering Event, out of its authorized and 
unissued Common Shares and/or other securities), the number of Preferred 
Shares (and, following the occurrence of the Triggering Event, Common Shares 
and/or other securities) that will be sufficient to permit the exercise in 
full of all outstanding Rights.

                  (b) If the Company shall hereafter list any of its 
Preferred Shares on a national securities exchange, then so long as the 
Preferred Shares (and, following the occurrence of a Triggering Event, Common 
Shares and/or other securities) issuable and deliverable upon exercise of the 
Rights may be listed on such exchange, the Company shall use its best efforts 
to cause, from and after such time as the Rights become exercisable (but only 
to the extent that it is reasonably likely that the Rights will be 
exercised), 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 Triggering Event in which the consideration to be

                                       -13-
<PAGE>

delivered by the Company upon exercise of the Rights is described in Section 
11(a)(ii) or Section 11(a)(iii) hereof, or as soon as is required by law 
following the Distribution Date, as the case may be, a registration statement 
under the Securities 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 Securities 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 expiration of the Rights. The Company 
may temporarily suspend, for a period 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, and notify 
the Rights Agent, that the exercisability of the Rights has been temporarily 
suspended, as well as a public announcement and notification to the Rights 
Agent at such time as the suspension is no longer in effect. 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. Notwithstanding any provision of this 
Agreement to the contrary, the Rights shall not be exercisable in any 
jurisdiction, unless the requisite qualification in such jurisdiction shall 
have been obtained, or an exemption therefrom shall be available, and until a 
registration statement has been declared effective.

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

                  (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 original issuance or delivery 
of the Rights Certificates or of any Preferred Shares (or other securities of 
the Company) 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 certificates or depositary receipts for the Preferred 
Shares (or other securities of the Company) in a name other than that of, the 
registered holder of the Rights Certificate evidencing Rights surrendered for 
exercise or to issue or to deliver any certificates or depositary receipts 
for Preferred Shares (or other securities of the Company) upon the exercise 
of any Rights until any 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. RECORD DATE. Each Person in whose name any certificate 
for a number of one-thousandths of a Preferred Share (or other securities of 
the Company) is issued upon the exercise of Rights shall for all purposes be 
deemed to have become the holder of record of Preferred Shares (or other 
securities of the Company) 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 Total Exercise Price with respect to 
which the Rights have been exercised (and any applicable transfer taxes)

                                       -14-
<PAGE>

was made; PROVIDED, HOWEVER, that if the date of such surrender and payment 
is a date upon which the transfer books of the Company are closed, such 
Person shall be deemed to have become the record holder of such shares on, 
and such certificate shall be dated, the next succeeding Business Day on 
which the 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 holder of Preferred Shares (or other securities 
of the Company) 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 EXERCISE PRICE, NUMBER OF SHARES OR NUMBER 
OF RIGHTS. The Exercise Price, the number and kind of shares or other 
property 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)  Anything in this Agreement to the contrary 
notwithstanding, in the event the Company shall at any time after the date of 
this Agreement (A) declare a dividend on the Preferred Shares payable in 
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine 
the outstanding Preferred Shares (by reverse stock split or otherwise) into a 
smaller number of Preferred Shares, or (D) issue any shares of its capital 
stock in a reclassification of the Preferred Shares (including any such 
reclassification in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation), then, in each such 
event, except as otherwise provided in this Section 11 and Section 7(e) 
hereof: (1) the Exercise Price in effect at the time of the record date for 
such dividend or of the effective date of such subdivision, combination or 
reclassification shall be adjusted so that the Exercise Price thereafter 
shall equal the result obtained by dividing the Exercise Price in effect 
immediately prior to such time by a fraction (the "ADJUSTMENT FRACTION"), the 
numerator of which shall be the total number of Preferred Shares (or shares 
of capital stock issued in such reclassification of the Preferred Shares) 
outstanding immediately following such time and the denominator of which 
shall be the total number of Preferred Shares outstanding immediately prior 
to such time; PROVIDED, HOWEVER, that in no event shall the consideration to 
be paid upon the exercise of one Right be less than the aggregate par value 
of the shares of capital stock of the Company issuable upon exercise of such 
Right; and (2) the number of one-thousandths of a Preferred Share (or share 
of such other capital stock) issuable upon the exercise of each Right shall 
equal the number of one-thousandths of a Preferred Share (or share of such 
other capital stock) as was issuable upon exercise of a Right immediately 
prior to the occurrence of the event described in clauses (A)-(D) of this 
Section 11(a)(i), multiplied by the Adjustment Fraction; provided, however, 
that, no such adjustment shall be made pursuant to this Section 11(a)(i) to 
the extent that there shall have simultaneously occurred an event described 
in clause (A), (B), (C) or (D) of Section 11(n) with a proportionate 
adjustment being made thereunder. Each Common Share that shall become 
outstanding after an adjustment has been made pursuant to this Section 
11(a)(i) shall have associated with the number of Rights, exercisable at the 
Exercise Price and for the number of one-thousandths of a Preferred Share (or 
shares of such other capital stock) as one Common Share has associated with 
it immediately following the adjustment made pursuant to this Section 
11(a)(i).

                                       -15-
<PAGE>

                         (ii) Subject to Section 24 of this Agreement, in the 
event a Triggering Event shall have occurred, then promptly following such 
Triggering Event each holder of a Right, except as provided in Section 7(e) 
hereof, shall thereafter have the right to receive for each Right, upon 
exercise thereof in accordance with the terms of this Agreement and payment 
of the Total Exercise Price in effect immediately prior to the occurrence of 
the Triggering Event, in lieu of a number of one-thousandths of a Preferred 
Share, such number of Common Shares of the Company as shall equal the result 
obtained by multiplying the Exercise Price in effect immediately prior to the 
occurrence of the Triggering Event by the number of one-thousandths of a 
Preferred Share for which a Right was exercisable (or would have been 
exercisable if the Distribution Date had occurred) immediately prior to the 
first occurrence of a Triggering Event, and dividing that product by 50% of 
the Current Per Share Market Price for Common Shares on the date of 
occurrence of the Triggering Event; provided, however, that the Exercise 
Price and the number of Common Shares of the Company so receivable upon 
exercise of a Right shall be subject to further adjustment as appropriate in 
accordance with Section 11(e) hereof to reflect any events occurring in 
respect of the Common Shares of the Company after the occurrence of the 
Triggering Event.

                         (iii)  In lieu of issuing Common Shares in 
accordance with Section 11(a)(ii) hereof, the Company may, if the Company's 
Board of Directors determines that such action is necessary or appropriate 
and not contrary to the interest of holders of Rights (and, in the event that 
the number of Common Shares which are authorized by the Company's Certificate 
of Incorporation but not outstanding or reserved for issuance for purposes 
other than upon exercise of the Rights are not sufficient to permit the 
exercise in full of the Rights, or if any necessary regulatory approval for 
such issuance has not been obtained by the Company), the Company shall: (A) 
determine the excess of (1) the value of the Common Shares issuable upon the 
exercise of a Right (the "CURRENT VALUE") over (2) the Exercise Price (such 
excess, the "SPREAD") and (B) with respect to each Right, make adequate 
provision to substitute for such Common Shares, upon exercise of the Rights, 
(1) cash, (2) a reduction in the Exercise Price, (3) other equity securities 
of the Company (including, without limitation, shares or units of shares of 
any series of preferred stock which the Company's Board of Directors has 
deemed to have the same value as Common Shares (such shares or units of 
shares of preferred stock are herein called "COMMON STOCK EQUIVALENTS")), 
except to the extent that the Company has not obtained any necessary 
stockholder or regulatory approval for such issuance, (4) debt securities of 
the Company, except to the extent that the Company has not obtained any 
necessary stockholder or regulatory approval for such issuance, (5) other 
assets, or (6) any combination of the foregoing, having an aggregate value 
equal to the Current Value, where such aggregate value has been determined by 
the Company's Board of Directors based upon the advice of a nationally 
recognized investment banking firm selected by the Company's Board of 
Directors; PROVIDED, HOWEVER, if the Company shall not have made adequate 
provision to deliver value pursuant to clause (B) above within thirty (30) 
days following the later of (x) the first occurrence of a Triggering 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 Exercise Price, Common Shares (to the extent available), 
except to the extent that the Company has not obtained any necessary 
stockholder or regulatory approval for such issuance, and then, if necessary, 
cash, which shares and/or cash have an aggregate value equal to the Spread. 
If

                                       -16-
<PAGE>

the Company's Board of Directors shall determine in good faith that it is 
likely that sufficient additional Common Shares could be authorized for 
issuance upon exercise in full of the Rights or that any necessary regulatory 
approval for such issuance will be obtained, 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 
or take action to obtain such regulatory approval (such period, as it may be 
extended, the "SUBSTITUTION PERIOD"). To the extent that the Company 
determines that some action need be taken pursuant to the first and/or second 
sentences of this Section 11(a)(iii), the Company (x) shall provide, subject 
to Section 7(e) hereof, that such action shall apply uniformly to all 
outstanding Rights and (y) may suspend the exercisability of the Rights until 
the expiration of the Substitution Period in order to seek any authorization 
of additional shares, to take any action to obtain any required regulatory 
approval and/or to decide the appropriate form of distribution to be made 
pursuant to such first sentence and to determine the value thereof. In the 
event of any such suspension, the Company shall issue a public announcement 
stating that the exercisability of the Rights has been temporarily suspended, 
as well as a public announcement at such time as the suspension is no longer 
in effect. For purposes of this Section 11(a)(iii), the value of the Common 
Shares shall be the Current Per Share Market Price of the Common Shares on 
the Section 11(a)(ii) Trigger Date and the value of any Common Stock 
Equivalent shall be deemed to have the same value as the Common Shares on 
such date.

                  (b) In case the Company shall, at any time after the date 
of this Agreement, fix a record date for the issuance of rights, options or 
warrants to all holders of Preferred Shares entitling such holders (for a 
period expiring within forty-five (45) calendar days after such record date) 
to subscribe for or purchase Preferred Shares or Equivalent Shares or 
securities convertible into Preferred Shares or Equivalent Shares at a price 
per share (or having a conversion price per share, if a security convertible 
into Preferred Shares or Equivalent Shares) less than the then Current Per 
Share Market Price of the Preferred Shares or Equivalent Shares on such 
record date, then, in each such case, the Exercise Price to be in effect 
after such record date shall be determined by multiplying the Exercise Price 
in effect immediately prior to such record date by a fraction, the numerator 
of which shall be the number of Preferred Shares and Equivalent Shares (if 
any) outstanding on such record date, plus the number of Preferred Shares or 
Equivalent Shares, as the case may be, which the aggregate offering price of 
the total number of Preferred Shares or Equivalent Shares, as the case may 
be, to be offered or issued (and/or the aggregate initial conversion price of 
the convertible securities to be offered or issued) would purchase at such 
current market price, and the denominator of which shall be the number of 
Preferred Shares and Equivalent Shares (if any) outstanding on such record 
date, plus the number of additional Preferred Shares or Equivalent Shares, as 
the case may be, to be offered for subscription or purchase (or into which 
the convertible securities so to be offered are initially convertible); 
PROVIDED, HOWEVER, that in no event shall the consideration to be paid upon 
the exercise of one Right be less than the aggregate par value of the shares 
of capital stock of the Company issuable upon exercise of one Right. In case 
such subscription price may be paid in a consideration part or all of which 
shall be in a form other than cash, the value of such consideration shall be 
as determined in good faith by the Company's Board of Directors, 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. 
Preferred Shares and Equivalent Shares owned by or held for the account of 
the Company shall not be deemed outstanding for the purpose of

                                       -17-
<PAGE>

any such computation. Such adjustment shall be made successively whenever 
such a record date is fixed, and in the event that such rights, options or 
warrants are not so issued, the Exercise Price shall be adjusted to be the 
Exercise Price which would then be in effect if such record date had not been 
fixed.

                  (c) In case the Company shall, at any time after the date 
of this Agreement, fix a record date for the making of a distribution to all 
holders of the Preferred Shares or of any class or series of Equivalent 
Shares (including any such distribution made in connection with a 
consolidation or merger in which the Company is the continuing or surviving 
corporation) of evidences of indebtedness or assets (other than a regular 
quarterly cash dividend, if any, or a dividend payable in Preferred Shares) 
or subscription rights, options or warrants (excluding those referred to in 
Section 11(b)), then, in each such case, the Exercise Price to be in effect 
after such record date shall be determined by multiplying the Exercise Price 
in effect immediately prior to such record date by a fraction, the numerator 
of which shall be the Current Per Share Market Price of a Preferred Share or 
an Equivalent Share on such record date, less the fair market value per 
Preferred Share or Equivalent Share (as determined in good faith by the Board 
of Directors of the Company, whose determination shall be described in a 
statement filed with the Rights Agent) 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 Preferred Share or Equivalent Share, as the case 
may be, and the denominator of which shall be such Current Per Share Market 
Price of a Preferred Share or Equivalent Share on such record date; PROVIDED, 
HOWEVER, that in no event shall the consideration to be paid upon the 
exercise of one Right be less than the aggregate par value of the shares of 
capital stock of the Company issuable upon exercise of one Right. Such 
adjustments shall be made successively whenever such a record date is fixed, 
and in the event that such distribution is not so made, the Exercise Price 
shall be adjusted to be the Exercise Price which would have been in effect if 
such record date had not been fixed.

                  (d) Anything herein to the contrary notwithstanding, no 
adjustment in the Exercise Price shall be required unless such adjustment 
would require an increase or decrease of at least 1% in the Exercise Price; 
PROVIDED, HOWEVER, that any adjustments which by reason of this Section 11(d) 
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 Common Share 
or other share or one hundred-thousandth of a Preferred Share, as the case 
may be. Notwithstanding the first sentence of this Section 11(d), 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 
requires such adjustment or (ii) the Expiration Date.

                  (e) If as a result of an adjustment made pursuant to 
Section 11(a) or 13(a) hereof, the holder of any Right thereafter exercised 
shall become entitled to receive any shares of capital stock other than 
Preferred Shares, thereafter the number of such other shares so receivable 
upon exercise of any Right and, if required, the Exercise 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 Shares contained in Sections 11(a), 11(b), 11(c), 11(d), 11(g), 
11(h), 11(i), 11(j), 11(k) and 11(l), and the provisions of Sections 7, 9, 
10, 13 and 14 with respect to the Preferred Shares shall apply on like terms 
to any such other shares.

<PAGE>

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

                  (g) Unless the Company shall have exercised its election as 
provided in Section 11(h), upon each adjustment of the Exercise 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 Exercise Price, 
that number of Preferred Shares (calculated to the nearest one 
hundred-thousandth of a share) obtained by (i) multiplying (x) the number of 
Preferred Shares covered by a Right immediately prior to this adjustment, by 
(y) the Exercise Price in effect immediately prior to such adjustment of the 
Exercise Price, and (ii) dividing the product so obtained by the Exercise 
Price in effect immediately after such adjustment of the Exercise Price.

                  (h) The Company may elect on or after the date of any 
adjustment of the Exercise Price as a result of the calculations made in 
Section 11(b) or (c) to adjust the number of Rights, in substitution for any 
adjustment in the number of Preferred Shares purchasable upon the exercise of 
a Right. Each of the Rights outstanding after such adjustment of the number 
of Rights shall be exercisable for the number of one-thousandths of a 
Preferred Share for which a Right was exercisable immediately prior to such 
adjustment. Each Right held of record prior to such adjustment of the number 
of Rights shall become that number of Rights (calculated to the nearest one 
hundred-thousandth) obtained by dividing the Exercise Price in effect 
immediately prior to adjustment of the Exercise Price by the Exercise Price 
in effect immediately after adjustment of the Exercise 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 Exercise 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(h), 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 Exercise 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.

                  (i) Irrespective of any adjustment or change in the 
Exercise Price or the number of Preferred Shares issuable upon the exercise 
of the Rights, the Rights Certificates theretofore and thereafter issued may 
continue to express the Exercise Price per one one-thousandth of a Preferred 
Share

                                       -19-
<PAGE>

and the number of one-thousandths of a Preferred Share which were expressed 
in the initial Rights Certificates issued hereunder.

                  (j) Before taking any action that would cause an adjustment 
reducing the Exercise Price below the par or stated value, if any, of the 
number of one-thousandths of a Preferred Share 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 as fully paid and nonassessable shares such number of 
one-thousandths of a Preferred Share at such adjusted Exercise Price.

                  (k) In any case in which this Section 11 shall require that 
an adjustment in the Exercise Price be made effective as of a record date for 
a specified event, the Company may elect to defer until the occurrence of 
such event the issuing to the holder of any Right exercised after such record 
date of the number of one-thousandths of a Preferred Share and other capital 
stock or securities of the Company, if any, issuable upon such exercise over 
and above the number of one-thousandths of a Preferred Share and other 
capital stock or securities of the Company, if any, issuable upon such 
exercise on the basis of the Exercise 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) upon the occurrence 
of the event requiring such adjustment.

                  (l) Anything in this Section 11 to the contrary 
notwithstanding, prior to the Distribution Date, the Company shall be 
entitled to make such reductions in the Exercise Price, in addition to those 
adjustments expressly required by this Section 11, as and to the extent that 
it in its sole discretion shall determine to be advisable in order that any 
(i) consolidation or subdivision of the Preferred or Common Shares, (ii) 
issuance wholly for cash of any Preferred or Common Shares at less than the 
current market price, (iii) issuance wholly for cash of Preferred or Common 
Shares or securities which by their terms are convertible into or 
exchangeable for Preferred or Common Shares, (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 or Common Shares 
shall not be taxable to such stockholders.

                  (m) The Company covenants and agrees that, after the 
Distribution Date, it will not, except as permitted by Sections 23, 24 or 27 
hereof, take (or permit to be taken) 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.

                  (n) In the event the Company shall at any time after the 
date of this Agreement (A) declare a dividend on the Common Shares payable in 
Common Shares, (B) subdivide the outstanding Common Shares, (C) combine the 
outstanding Common Shares (by reverse stock split or otherwise) into a 
smaller number of Common Shares, or (D) issue any shares of its capital stock 
in a reclassification of the Common Shares (including any such 
reclassification in connection with a consolidation or merger in which the 
Company is the continuing or surviving corporation), then, in each such 
event, except as otherwise provided in this Section 11(n) and Section 7(e) 
hereof: (1) each Common

                                       -20-
<PAGE>

Share (or shares of capital stock issued in such reclassification of the 
Common Shares) outstanding immediately following such time shall have 
associated with it the number of Rights as were associated with one Common 
Share immediately prior to the occurrence of the event described in clauses 
(A)-(D) above; (2) the Exercise Price in effect at the time of the record 
date for such dividend or of the effective date of such subdivision, 
combination or reclassification shall be adjusted so that the Exercise Price 
thereafter shall equal the result obtained by multiplying the Exercise Price 
in effect immediately prior to such time by a fraction, the numerator of 
which shall be the total number of Common Shares outstanding immediately 
prior to the event described in clauses (A)-(D) above, and the denominator of 
which shall be the total number of Common Shares outstanding immediately 
after such event; PROVIDED, HOWEVER, that in no event shall the consideration 
to be paid upon the exercise of one Right be less than the aggregate par 
value of the shares of capital stock of the Company issuable upon exercise of 
such Right; and (3) the number of one-thousandths of a Preferred Share (or 
shares of such other capital stock) issuable upon the exercise of each Right 
outstanding after such event shall equal the number of one-thousandths of a 
Preferred Share (or shares of such other capital stock) as were issuable with 
respect to one Right immediately prior to such event. Each Common Share that 
shall become outstanding after an adjustment has been made pursuant to this 
Section 11(n) shall have associated with it the number of Rights, exercisable 
at the Exercise Price and for the number of one-thousandths of a Preferred 
Share (or shares of such other capital stock) as one Common Share has 
associated with it immediately following the adjustment made pursuant to this 
Section 11(n). If an event occurs which would require an adjustment under 
both this Section 11(n) and Section 11(a)(ii) hereof, the adjustment provided 
for in this Section 11(n) shall be in addition to, and shall be made prior 
to, any adjustment required pursuant to Section 11(a)(ii) hereof.

         Section 12. CERTIFICATE OF ADJUSTED EXERCISE PRICE OR NUMBER OF 
SHARES. Whenever an adjustment is made as provided in Sections 11 and 13 
hereof, the Company shall promptly (a) prepare a certificate setting forth 
such adjustment and a brief statement of the facts accounting for such 
adjustment, (b) file with the Rights Agent and with each transfer agent for 
the Preferred Shares a copy of such certificate, and (c) mail a brief summary 
thereof to each holder of a Rights Certificate in accordance with Section 26 
hereof. Notwithstanding the foregoing sentence, the failure of the Company to 
make such certification or give such notice shall not affect the validity of 
such adjustment or the force or effect of the requirement for such 
adjustment. The Rights Agent shall be fully protected in relying on any such 
certificate and on any adjustment contained therein and shall not be deemed 
to have knowledge of such adjustment unless and until it shall have received 
such certificate.

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

                  (a) In the event that, following a Triggering Event, 
directly or indirectly:

                         (i) the Company shall consolidate with, or 
         merge with and into, any other Person (other than a wholly-owned 
         Subsidiary of the Company in a transaction the principal purpose of 
         which is to change the state of incorporation of the Company and 
         which complies with Section 11(m) hereof);


                                     -21-
<PAGE>

                           (ii) any Person shall consolidate with the 
          Company, or merge with and into the Company and the Company shall 
          be the continuing or surviving corporation of such consolidation or 
          merger and, in connection with such merger, all or part of the 
          Common Shares shall be changed into or exchanged for stock or other 
          securities of any other person (or of the Company); or
          
                          (iii) the Company shall sell or otherwise transfer 
          (or one or more of its Subsidiaries shall sell or otherwise 
          transfer), in one or more transactions, assets or earning power 
          aggregating 50% or more of the assets or earning power of the 
          Company and its Subsidiaries (taken as a whole) to any other Person 
          or Persons (other than the Company or one or more of its 
          wholly-owned Subsidiaries in one or more transactions, each of 
          which individually (and together) complies with Section 11(m) 
          hereof),

                          then, concurrent with and in each such case,

                                    (A) each holder of a Right (except as 
                  provided in Section 7(e) hereof) shall thereafter have 
                  the right to receive, upon the exercise thereof at a 
                  price equal to the Total Exercise Price applicable 
                  immediately prior to the occurrence of the Section 13 
                  Event in accordance with the terms of this Agreement, 
                  such number of validly authorized and issued, fully paid, 
                  nonassessable and freely tradeable Common Shares of the 
                  Principal Party (as hereinafter defined), free of any 
                  liens, encumbrances, rights of first refusal or other 
                  adverse claims, as shall be equal to the result obtained 
                  by dividing such Total Exercise Price by 50% of the 
                  Current Per Share Market Price of the Common Shares of 
                  such Principal Party on the date of consummation of such 
                  Section 13 Event, PROVIDED, HOWEVER, that the Exercise 
                  Price and the number of Common Shares of such Principal 
                  Party so receivable upon exercise of a Right shall be 
                  subject to further adjustment as appropriate in 
                  accordance with Section 11(e) hereof;
                  
                                    (B) 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;
                  
                                    (C) 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;
                  
                                    (D) such Principal Party shall take 
                  such steps (including, but not limited to, the 
                  reservation of a sufficient number of its Common Shares) 
                  in connection with the consummation of any such 
                  transaction as may be necessary to ensure that the 
                  provisions hereof shall thereafter be applicable, as 
                  nearly as reasonably may be, in relation to its Common 
                  Shares thereafter deliverable upon the exercise of the 
                  Rights; and

<PAGE>

                                    (E) upon the subsequent occurrence of 
                  any consolidation, merger, sale or transfer of assets or 
                  other extraordinary transaction in respect of such 
                  Principal Party, each holder of a Right shall thereupon 
                  be entitled to receive, upon exercise of a Right and 
                  payment of the Total Exercise Price as provided in this 
                  Section 13(a), such cash, shares, rights, warrants and 
                  other property which such holder would have been entitled 
                  to receive had such holder, at the time of such 
                  transaction, owned the Common Shares of the Principal 
                  Party receivable upon the exercise of such Right pursuant 
                  to this Section 13(a), and such Principal Party shall 
                  take such steps (including, but not limited to, 
                  reservation of shares of stock) as may be necessary to 
                  permit the subsequent exercise of the Rights in 
                  accordance with the terms hereof for such cash, shares, 
                  rights, warrants and other property.
                  
                                    (F) For purposes hereof, the "earning 
                  power" of the Company and its Subsidiaries shall be 
                  determined in good faith by the Company's Board of 
                  Directors on the basis of the operating earnings of each 
                  business operated by the Company and its Subsidiaries 
                  during the three fiscal years preceding the date of such 
                  determination (or, in the case of any business not 
                  operated by the Company or any Subsidiary during three 
                  full fiscal years preceding such date, during the period 
                  such business was operated by the Company or any 
                  Subsidiary).

                  (b) For purposes of this Agreement, the term "PRINCIPAL PARTY"
shall mean:

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

                          (ii) in the case of any transaction described in 
         clause (iii) of Section 13(a) hereof, the Person that is the party 
         receiving the greatest portion of the assets or earning power 
         transferred pursuant to such transaction or transactions, or, if 
         more than one Person that is a party to such transaction or 
         transactions receives the same portion of the assets or earning 
         power so transferred and each such portion would, were it not for 
         the other equal portions, constitute the greatest portion of the 
         assets or earning power so transferred, or if the Person receiving 
         the greatest portion of the assets or earning power cannot be 
         determined, whichever of such Persons is the issuer of Common 
         Shares having the greatest aggregate market value of shares 
         outstanding;

                                      -23-

PROVIDED, HOWEVER, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time or
have not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of which are and have been so registered, the term "Principal
Party" shall refer to whichever of such Persons is the issuer of Common Shares
having the greatest aggregate market value of shares outstanding, or (3) if such
Person is owned, directly or indirectly, by a joint venture formed by two or
more Persons that are not owned, directly or indirectly by the same Person, the
rules set forth in clauses (1) and (2) above shall apply to each of the owners
having an interest in the venture as if the Person owned by the joint venture
was a Subsidiary of both or all of such joint venturers, and the Principal Party
in each such case shall bear the obligations set forth in this Section 13 in the
same ratio as its interest in such Person bears to the total of such interests.

                  (c) The Company shall not consummate any Section 13 Event
unless the Principal Party shall have a sufficient number of authorized Common
Shares that have not been issued or reserved for issuance to permit the exercise
in full of the Rights in accordance with this Section 13 and unless prior
thereto the Company and such issuer shall have executed and delivered to the
Rights Agent a supplemental agreement confirming that such Principal Party
shall, upon consummation of such Section 13 Event, assume this Agreement in
accordance with Sections 13(a) and 13(b) hereof, that all rights of first
refusal or preemptive rights in respect of the issuance of Common Shares of such
Principal Party upon exercise of outstanding Rights have been waived, that there
are no rights, warrants, instruments or securities outstanding or any agreements
or arrangements which, as a result of the consummation of such transaction,
would eliminate or substantially diminish the benefits intended to be afforded
by the Rights and that such transaction shall not result in a default by such
Principal Party under this Agreement, and further providing that, as soon as
practicable after the date of such Section 13 Event, such Principal Party will:

                           (i) prepare and file a registration statement 
         under the Securities Act with respect to the Rights and the 
         securities purchasable upon exercise of the Rights on an 
         appropriate form, use its best efforts to cause such registration 
         statement to become effective as soon as practicable after such 
         filing and use its best efforts to cause such registration 
         statement to remain effective (with a prospectus at all times 
         meeting the requirements of the Securities Act) until the 
         Expiration Date, and similarly comply with applicable state 
         securities laws;
         
                          (ii) use its best efforts to list (or continue the 
         listing of) the Rights and the securities purchasable upon exercise 
         of the Rights on a national securities exchange or to meet the 
         eligibility requirements for quotation on Nasdaq and list (or 
         continue the listing of) the Rights and the securities purchasable 
         upon exercise of the Rights on Nasdaq; and
         
                         (iii) deliver to holders of the Rights historical 
         financial statements for such Principal Party which comply in all 
         respects with the requirements for registration on Form 10 (or any 
         successor form) under the Exchange Act.

                                      -24-

<PAGE>

         In the event that at any time after the occurrence of a Triggering
Event some or all of the Rights shall not have been exercised at the time of a
transaction described in this Section 13, the Rights which have not theretofore
been exercised shall thereafter be exercisable in the manner described in
Section 13(a) (without taking into account any prior adjustment required by
Section 11(a)(ii)).

                  (d) In case the "Principal Party" for purposes of Section
13(b) hereof has provision in any of its authorized securities or in its
certificate of incorporation or by-laws or other instrument governing its
corporate affairs, which provision would have the effect of (i) causing such
Principal Party to issue (other than to holders of Rights pursuant to Section 13
hereof), in connection with, or as a consequence of, the consummation of a
Section 13 Event, Common Shares or Equivalent Shares of such Principal Party at
less than the then Current Per Share Market Price thereof or securities
exercisable for, or convertible into, Common Shares or Equivalent Shares of such
Principal Party at less than such then Current Per Share Market Price, or (ii)
providing for any special payment, tax or similar provision in connection with
the issuance of the Common Shares of such Principal Party pursuant to the
provisions of Section 13 hereof, then, in such event, the Company hereby agrees
with each holder of Rights that it shall not consummate any such transaction
unless prior thereto the Company and such Principal Party shall have executed
and delivered to the Rights Agent a supplemental agreement providing that the
provision in question of such Principal Party shall have been canceled, waived
or amended, or that the authorized securities shall be redeemed, so that the
applicable provision will have no effect in connection with or as a consequence
of, the consummation of the proposed transaction.

                  (e) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, effect or permit to occur any Section 13
Event, if (i) at the time or immediately after such Section 13 Event 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, (ii) prior to,
simultaneously with or immediately after such Section 13 Event, the stockholders
of the Person who constitutes, or would constitute, the "Principal Party" for
purposes of Section 13(b) hereof shall have received a distribution of Rights
previously owned by such Person or any of its Affiliates or Associates or (iii)
the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

                  (f) The provisions of this Section 13 shall similarly apply to
successive mergers or consolidations or sales or other transfers.

         Section 14.  FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

                  (a) The Company shall not be required to issue fractions of
Rights or to distribute Rights Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid 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 the purposes of this Section 14(a),
the current market value of a whole Right shall be the closing price of the
Rights for the Trading Day immediately prior to the date on which such


                                      -25-

<PAGE>

fractional Rights would have been otherwise issuable, as determined pursuant 
to the second sentence of Section 1(j) hereof.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions that are integral multiples of one one-thousandth of a Preferred
Share). Interests in fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, pursuant to an appropriate agreement between
the Company and a depositary selected by it; PROVIDED, that such agreement shall
provide that the holders of such depositary receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth of a Preferred Share, the Company shall pay to the registered
holders of Rights Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of a Preferred Share. For purposes of this Section 14(b), the current
market value of a Preferred Share shall be one thousand times the closing price
of a Common Share (as determined pursuant to the second sentence of Section 1(j)
hereof) for the Trading Day immediately prior to the date of such exercise.

                  (c) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares upon the exercise or exchange of Rights. In lieu of such fractional
Common Shares, the Company shall pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of a Common
Share. For purposes of this Section 14(c), the current market value of a Common
Share shall be the closing price of a Common Share (as determined pursuant to
the second sentence of Section 1(j) hereof) for the Trading Day immediately
prior to the date of such exercise.

                  (d) The holder of a Right by the acceptance of the Right
expressly waives his or her right to receive any fractional Rights or any
fractional shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of a Right.

         Section 15. RIGHTS OF ACTION. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Rights Certificate (or, prior
to the Distribution Date, of the Common Shares), without the consent of the
Rights Agent or of the holder of any other Rights Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in his or her own behalf and for
his or her 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 or her 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 


                                      -26-

<PAGE>

this Agreement and will be entitled to specific performance of the 
obligations under, and injunctive relief against actual or threatened 
violations of, the obligations of any Person subject to this Agreement.

         Section 16. AGREEMENT OF 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 the Common Shares;

                  (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; and

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

         Section 17. 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 to be the holder of the Preferred Shares
or any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any 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
other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability or expense, incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability in the premises. 


                                      -27-

<PAGE>

In no event will the Rights Agent be liable for special, indirect, incidental 
or consequential loss or damage of any kind whatsoever, even if the Rights 
Agent has been advised of the possibility of such loss or damage.

                  (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 the Preferred Shares or Common Shares 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 reasonably believed by it to
be genuine and to be signed, executed and, where necessary, verified or
acknowledged, by the proper Person or Persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

         Section 19.  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.

                  (a) Any corporation into which the Rights Agent or any 
successor Rights Agent may be merged or with which it may be consolidated, or 
any corporation resulting from any merger or consolidation to which the 
Rights Agent or any successor Rights Agent shall be a party, or any 
corporation succeeding to the corporate trust business of the Rights Agent or 
any successor Rights Agent, shall be the successor to the Rights Agent under 
this Agreement without the execution or filing of any paper or any further 
act on the part of any of the parties hereto; PROVIDED, HOWEVER, that such 
corporation would be eligible for appointment as a successor Rights Agent 
under the provisions of Section 21 hereof. In case at the time such successor 
Rights Agent shall succeed to the agency created by this Agreement, any of 
the Rights Certificates shall have been countersigned but not delivered, any 
such successor Rights Agent may adopt the countersignature of the 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 Rights Agent 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:


                                      -28-

<PAGE>

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

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person and
the determination of Current Per Share 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 any one of the Chairman of the Board, the Chief Executive
Officer, the President, any Vice President, the Chief Financial Officer, the
Secretary or any Assistant Secretary of the Company and delivered to the Rights
Agent; and such certificate shall be full authorization to the Rights Agent for
any action taken or suffered in good faith by it under the provisions of this
Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable hereunder to the Company
and any other Person only for its own gross negligence, bad faith or willful
misconduct.

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

                  (e) The Rights Agent shall not be under any responsibility 
in respect of the validity of this Agreement or the execution and delivery 
hereof (except the due execution hereof by the Rights Agent) or in respect of 
the validity or execution of any 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 change in the 
exercisability of the Rights or any adjustment in the terms of the Rights 
(including the manner, method or amount thereof) provided for in Sections 3, 
11, 13, 23 or 24, or the ascertaining of the existence of facts that would 
require any such change or adjustment (except with respect to the exercise of 
Rights evidenced by Rights Certificates after receipt by the Rights Agent of 
a certificate furnished pursuant to Section 12 describing such change or 
adjustment); nor shall it by any act hereunder be deemed to make any 
representation or warranty as to the authorization or reservation of any 
Preferred Shares to be issued pursuant to this Agreement or any Rights 
Certificate or as to whether any Preferred Shares will, when issued, be 
validly authorized and issued, fully paid and nonassessable.

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

<PAGE>

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
any one of the Chairman of the Board, the Chief Executive Officer, the
President, any Vice President, the Chief Financial Officer, the Secretary or any
Assistant Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered by it in good faith in accordance with instructions of
any such officer or for any delay in acting while waiting for those
instructions. Any application by the Rights Agent for written instructions from
the Company may, at the option of the Rights Agent, set forth in writing any
action proposed to be taken or omitted by the Rights Agent under this Rights
Agreement and the date on and/or after which such action shall be taken or such
omission shall be effective. The Rights Agent shall not be liable for any action
taken by, or omission of, the Rights Agent in accordance with a proposal
included in any such application on or after the date specified in such
application (which date shall not be less than five (5) Business Days after the
date any officer of the Company actually receives such application, unless any
such officer shall have consented in writing to an earlier date) unless, prior
to taking any such action (or the effective date in the case of an omission),
the Rights Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted.

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

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

                  (j) 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.


                                      -30-

         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 Preferred Shares and the Common Shares by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) days' notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of the Preferred
Shares and the Common Shares by registered or certified mail, and 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 or her Rights
Certificate for inspection by the Company), then the 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 corporation organized and doing
business under the laws of the United States or of any state of the United
States, in good standing, which is authorized under such laws to exercise
corporate trust or stockholder services powers and is subject to supervision or
examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $50
million. 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 Preferred
Shares and the Common Shares, and 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.

                  (a) Notwithstanding any of the provisions of this Agreement or
of the Rights to the contrary, the Company may, at its option, issue new Rights
Certificates evidencing Rights in such form as may be approved by its Board of
Directors to reflect any adjustment or change in the Exercise 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 Common Shares
following the Distribution Date and prior to the redemption or expiration of the
Rights, the Company (a) shall, with respect to Common Shares so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement or upon the exercise, conversion or exchange of other securities of
the Company outstanding at the date hereof or upon the exercise, conversion or
exchange of securities hereinafter 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


                                      -31-

<PAGE>

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 and this sentence shall be null and void 
AB INITIO if, and to the extent that, such issuance or this sentence would 
create a significant risk of or result in material adverse tax consequences 
to the Company or the Person to whom such Rights Certificate would be issued 
or would create a significant risk of or result in such options' or employee 
plans' or arrangements' failing to qualify for otherwise available special 
tax treatment 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.

                  (b) Notwithstanding any of the provisions of this Agreement or
of the Rights to the contrary, in the event a holder of the Company's Preferred
Stock Redeemable 2010 (the "CELLNET REDEEMABLE PREFERRED STOCK") receives a
request on or prior to the Expiration Date from a holder of 7% Exchangeable
Limited Liability Company Preferred Securities Mandatorily Redeemable 2010 (the
"FUNDING PREFERRED SECURITIES") of CellNet Funding, LLC, a Delaware limited
liability company, to exchange Funding Preferred Securities for Common Shares (a
"FUNDING PREFERRED SECURITIES EXCHANGE"), the holder of such Funding Preferred
Securities shall be entitled to receive in connection with such Funding
Preferred Securities Exchange such number of Rights (or such other consideration
required pursuant to this Agreement or as the Board of Directors otherwise
considers appropriate) as would be required to be issued under this Agreement to
a holder of the same number of Common Shares as the holder of Funding Preferred
Securities is entitled to receive in connection with the Funding Preferred
Securities Exchange, whether or not the Distribution Date has then occurred. No
holder of Funding Preferred Securities receiving Common Shares with Rights
attached (on or prior to the Distribution Date and on or prior to the Expiration
Date) in a Funding Preferred Securities Exchange and no holder of Funding
Preferred Securities receiving Common Shares with Rights detached (following the
Distribution Date and on or prior to the Expiration Date) in a Funding Preferred
Securities Exchange, shall be entitled to any greater rights under this
Agreement than any other holder of Common Shares; and a Right (or such other
consideration required pursuant to this Agreement or as the Board of Directors
otherwise considers appropriate) issued to such prior holder of Funding
Preferred Securities shall be unexercisable or null and void to the same extent
as such Right (or such other consideration required pursuant to this Agreement
or as the Board of Directors otherwise considers appropriate) would be
unexercisable or null and void, as applicable, in the hands of any other holder
of Common Shares pursuant to the terms of this Agreement.

                  (c) Notwithstanding any of the provisions of this Agreement or
of the Rights to the contrary, in the event The Bank of New York, as the
Company's Warrant Agent, receives a request from a holder of the Company's
Warrants, each representing the right to purchase initially one share of Common
Stock, no par value per share, of the Company, issued in connection with the
issuance of the Company's 14% Senior Discount Notes due 2007, to exercise such
Warrants for Common Shares (a "WARRANT EXERCISE"), the holder of such Warrants
shall be entitled to receive in connection with such Warrant Excercise such
number of Rights (or such other consideration required pursuant to this
Agreement or as the Board of Directors otherwise considers appropriate) as would
be required to be issued under this Agreement to a holder of the same number of
Common Shares as the holder of Warrants is entitled to receive in connection
with the Warrant Exercise, whether or not the Distribution


                                      -32-

Date has then occurred. No holder of Warrants receiving Common Shares with 
Rights attached (on or prior to the Distribution Date and on or prior to the 
Expiration Date) in a Warrant Exercise and no holder of Warrants receiving 
Common Shares with Rights detached (following the Distribution Date and on or 
prior to the Expiration Date) in a Warrant Exercise, shall be entitled to any 
greater rights under this Agreement than any other holder of Common Shares; 
and a Right (or such other consideration required pursuant to this Agreement 
or as the Board of Directors otherwise considers appropriate) issued to such 
prior holder of Warrants shall be unexercisable or null and void to the same 
extent as such Right (or such other consideration required pursuant to this 
Agreement or as the Board of Directors otherwise considers appropriate) would 
be unexercisable or null and void, as applicable, in the hands of any other 
holder of Common Shares pursuant to the terms of this Agreement.

         Section 23.  REDEMPTION.

                  (a) The Company may, at its option and with the approval of 
the Board of Directors, at any time prior to the Close of Business on the 
earlier of the Shares Acquisition Date and the Final Expiration Date, redeem 
all but not less than all the then outstanding Rights at a redemption price 
of $0.001 per Right, appropriately adjusted to reflect any stock split, stock 
dividend or similar transaction occurring after the date hereof (such 
redemption price being herein referred to as the "REDEMPTION PRICE") and the 
Company may, at its option, pay the Redemption Price either in Common Shares 
(based on the Current Per Share Market Price thereof at the time of 
redemption) or cash. Such redemption of the Rights by the Company may be made 
effective at such time, on such basis and with such conditions as the Board 
of Directors in its sole discretion may establish. The date on which the 
Board of Directors elects to make the redemption effective shall be referred 
to as the "REDEMPTION DATE."

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

         Section 24.  EXCHANGE.

                  (a) Subject to applicable laws, rules and regulations, and 
subject to Section 24(c) hereof, the Company may, at its option, by 
majority vote of the Board of Directors, at any time after the occurrence of 
a Triggering Event, 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 Shares at an 
exchange ratio of one Common Share per Right, appropriately adjusted to 
reflect any stock split, stock dividend or similar transaction occurring 
after the date hereof (such exchange ratio being hereinafter referred to as 
the "EXCHANGE RATIO"). Notwithstanding the foregoing, the Board of Directors 
shall not be empowered to effect such exchange at any time after any 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 
Shares 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 Shares then outstanding.

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

                  (c) In the event that there shall not be sufficient Common 
Shares issued but not outstanding or authorized but unissued to permit any 
exchange of Rights as contemplated in accordance with Section 24(a) hereof, the 
Company shall either take such action as may be necessary to authorize 
additional Common Shares for issuance upon exchange of the Rights or 
alternatively, at the option of a majority of the Board of Directors, with 
respect to each Right (i) pay cash in an amount equal to the Current Value 
(as hereinafter defined), in lieu of issuing Common Shares in exchange 
therefor, or (ii) issue debt or equity securities or a combination thereof, 
having a value equal to the Current Value, in lieu of issuing Common Shares 
in exchange for each such Right, where the value of such securities shall be 
determined by a nationally recognized investment banking firm selected by 
majority vote of the Board of Directors, or (iii) deliver any combination of 
cash, property, Common Shares and/or other securities having a value equal to 
the Current Value in exchange for each Right. For purposes of this Section 
24(c) only, the Current Value shall mean the product of the Current Per Share 
Market Price of Common Shares on the date of the occurrence of the event 
described above in subparagraph (a), 

                                       -34-
<PAGE>

multiplied by the number of Common Shares for which the Right otherwise would 
be exchangeable if there were sufficient shares available. To the extent that 
the Company determines that some action need be taken pursuant to clauses 
(i), (ii) or (iii) of this Section 24(c), the Board of Directors may 
temporarily suspend the exercisability of the Rights for a period of up to 
sixty (60) days following the date on which the event described in Section 
24(a) hereof shall have occurred, in order to seek any authorization of 
additional Common Shares and/or to decide the appropriate form of 
distribution to be made pursuant to the above provision 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.

                  (d) The Company shall not be required to issue fractions of 
Common Shares or to distribute certificates which evidence fractional Common 
Shares. In lieu of such fractional Common Shares, there shall be paid to the 
registered holders of the Rights Certificates with regard to which such 
fractional Common Shares would otherwise be issuable, an amount in cash equal 
to the same fraction of the current market value of a whole Common Share (as 
determined pursuant to the second sentence of Section 11(k) hereof).

         Section 25.  NOTICE OF CERTAIN EVENTS.

                  (a) In case the Company shall propose to effect or permit 
to occur any Triggering Event or Section 13 Event, the Company shall give 
notice thereof to each holder of Rights in accordance with Section 26 hereof 
at least twenty (20) days prior to occurrence of such Triggering Event or 
such Section 13 Event.

                  (b) In case any Triggering Event or Section 13 Event shall 
occur, then, in any such case, the Company shall as soon as practicable 
thereafter give to each holder of a Rights Certificate, 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 Sections 11(a)(ii) and 13 hereof.

to be given or made by the Rights Agent or by the holder of any Rights

         Section 27. SUPPLEMENTS AND AMENDMENTS. Prior to the date of the 
occurrence of a Triggering Event, the Company may supplement or amend this 
Agreement in any respect without the approval of any holders of Rights and 
the Rights Agent shall, if the Company so directs, execute such supplement or 
amendment. From and after the occurrence of a Distribution Date, the Company

ambiguity, (ii) correct or supplement any provision contained herein which

shorten or lengthen any time period hereunder, or (iv) to change or 
supplement the provisions hereunder in any manner that the Company may deem 
necessary or desirable and that shall not adversely affect the interests of 
the holders of Rights (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, pursuant to clause (iii) of this 
sentence, (A) a time period relating to when the Rights may be redeemed at 
such time as the Rights are not then redeemable or (B) any other time period 
unless such lengthening is for the purpose of protecting, enhancing or 
clarifying the rights of, and/or the benefits to, the holders of Rights 
(other than an Acquiring Person or an Affiliate or Associate of an Acquiring 
Person). Upon the delivery of a certificate from an appropriate officer of 
the Company that 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 Shares.

         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 
Common Shares outstanding at any particular time, including for purposes of 
determining the particular percentage of such outstanding Common Shares of 
which any Person is the Beneficial Owner, shall be made in accordance with

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 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 Certificates and all other parties and (y) not subject 
the Board to any liability to the holders of the Rights.

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, the Common Shares) 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, the Common Shares).

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

Rights Certificate issued hereunder shall be deemed to be a contract made

                     SERIES A PARTICIPATING PREFERRED STOCK
                          OF CELLNET DATA SYSTEMS, INC.


         The undersigned, Paul G. Manca, does hereby certify:

         1.  That he is the duly elected and acting Vice President and Chief 
Financial Officer of CellNet Data Systems, Inc., a Delaware corporation (the 
"CORPORATION").

         2.  That pursuant to the authority conferred upon the Board of 
Directors by the Restated Certificate of Incorporation of the said 
Corporation, the said Board of Directors on November 24, 1998, adopted the 
following resolution authorizing a series of 100,000 shares of Preferred 
Stock designated as Series A Participating Preferred Stock:

         "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation by the Restated Certificate of Incorporation, the
Board of Directors does hereby provide for the issue of a series of Preferred
Stock of the Corporation and does hereby fix and herein state and express the
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions of such series of Preferred Stock
as follows:

         Section 1    DESIGNATION AND AMOUNT. The shares of such series shall 
be designated as "SERIES A PARTICIPATING PREFERRED STOCK." The Series A 
Participating Preferred Stock shall have a par value of $0.001 per share, and 
the number of shares constituting such series shall be 100,000.

         Section 2    PROPORTIONAL ADJUSTMENT. In the event the Corporation 
shall at any time after the date of the filing of this Certificate with the 
Secretary of State of Delaware (i) declare any dividend on Common Stock of 
the Corporation ("COMMON STOCK") payable in shares of Common Stock, (ii) 
subdivide the outstanding Common Stock, or (iii) combine the outstanding 
Common Stock into a smaller number of shares, then in each such case the 
Corporation shall simultaneously effect a proportional adjustment to the 
number of outstanding shares of Series A Participating Preferred Stock.

         Section 3    DIVIDENDS AND DISTRIBUTIONS.

                (a)   Subject to the prior and superior right of the holders 
of any shares of any series of Preferred Stock ranking prior and superior to 
the shares of Series A Participating Preferred Stock with respect to 
dividends, the holders of shares of Series A Participating Preferred Stock 
shall be entitled to receive when, as and if declared by the Board of 
Directors out of funds legally available for that purpose, quarterly 
dividends payable in cash on the last day of January, April, July and October 
in each year (each such date being referred to herein as a "QUARTERLY 
DIVIDEND PAYMENT DATE"), commencing on the first

                                      
<PAGE>

Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series A Participating Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to 1,000 times the aggregate per share
amount of all cash dividends, and 1,000 times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other (except
as provided in Section 2 hereof) than a dividend payable in shares of Common
Stock or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Participating Preferred Stock.

                (b)   The Corporation shall declare a dividend or 
distribution on the Series A 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).

                (c)   Dividends shall begin to accrue on outstanding shares 
of Series A Participating Preferred Stock from the Quarterly Dividend Payment 
Date next preceding the date of issue of such shares of Series A 
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 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 from such 
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear 
interest. Dividends paid on the shares of Series A 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 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 4    VOTING RIGHTS.  The holders of shares of Series A 
Participating Preferred Stock shall have the following voting rights:

                (a)   Each share of Series A Participating Preferred Stock 
shall entitle the holder thereof to 1,000 votes on all matters submitted to a 
vote of the stockholders of the Corporation.

                (b)   Except as otherwise provided herein or by law, the 
holders of shares of Series A 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)   Except as required by law, holders of Series A 
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 5    CERTAIN RESTRICTIONS.

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

                (b)   Whenever quarterly dividends or other dividends or 
distributions payable on the Series A Participating Preferred Stock as 
provided in Section 3 are in arrears, thereafter and until all accrued and 
unpaid dividends and distributions, whether or not declared, on shares of 
Series A 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 Participating Preferred Stock;

                            (ii)  declare or pay dividends on, make any other
distributions on any shares of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with Series A Participating
Preferred Stock, except dividends paid ratably on the Series A 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 Participating

                            (iv)  purchase or otherwise acquire for

publication (as determined by the Board of Directors) to all holders of such 
shares upon such terms as the Board of Directors, after consideration of the 
respective annual dividend rates and other relative rights and preferences of 
the respective series and classes, shall determine in good faith will result 
in fair and equitable treatment among the respective series or classes.

                (c)   The Corporation shall not permit any subsidiary of the 
Corporation to purchase or otherwise acquire for consideration any shares of 
stock of the Corporation unless the Corporation could, under paragraph (a) of

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

         Section 7    LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any 
liquidation, dissolution or winding up of the Corporation, the holders of 
shares of Series A Participating Preferred Stock shall be entitled to receive

distributed per share to holders of shares of Common Stock plus an amount 
equal to any accrued and unpaid dividends on such shares of Series A 
Participating Preferred Stock.

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

         Section 9    NO REDEMPTION. The shares of Series A Participating 
Preferred Stock shall not be redeemable.

         Section 10   RANKING. The Series A Participating Preferred Stock 
shall rank junior to all other series of the Corporation's Preferred Stock as

of any such series shall provide otherwise.

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

         Section 12   FRACTIONAL SHARES. Series A 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 Participating Preferred Stock.

         RESOLVED FURTHER, that the President or any Vice President and the
Secretary or any Assistant Secretary of this corporation be, and they hereby

                            STOCKHOLDER RIGHTS PLAN
 
                           CELLNET DATA SYSTEMS, INC.
 
 THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE COMPANY, AT $0.001
           PER RIGHT ON THE TERMS SET FORTH IN THE RIGHTS AGREEMENT.
 
                               SUMMARY OF RIGHTS
 
RIGHTS DIVIDEND DECLARATION
 
    On November 24, 1998 (the "Rights Dividend Declaration Date"), the Board of
Directors of CellNet Data Systems, Inc. ("CellNet" or the "Company") declared a
dividend of one right (a "Right") to purchase one one-thousandth (1/1000) of a
share of the Company's Series A Participating Preferred Stock, $0.001 par value
per share (the "Preferred Stock"), for each outstanding share of common stock,
par value $0.001 per share (the "Common Stock"). The dividend is payable to
stockholders of record on December 21, 1998 (the "Record Date"). In addition,
one Right shall be issued with each share of Common Stock that becomes
outstanding between the Record Date and the earlier to occur of the Distribution
Date (as defined below) and the Expiration Date (as defined below). This
includes Common Stock that is issued upon conversion of securities convertible
into or exchangeable for Common Stock such as stock options, warrants, and 7%
Exchangeable Preferred Securities Mandatorily Redeemable 2010 of CellNet
Funding, LLC, a wholly-owned subsidiary of the Company.
 
DISTRIBUTION OF RIGHTS
 
    Prior to the Distribution Date (as defined below), the Rights will be
evidenced by and trade with the Common Stock. After the Distribution Date, the
Rights will separate from the Common Stock and become transferable apart from
the Common Stock. As soon as practicable following the Distribution Date,
separate certificates evidencing the Rights will be mailed to holders of record
of Common Stock as of the close of business on the Distribution Date and such
certificates will then alone evidence such Rights.
 
    The Distribution Date will occur, if at all, on the earlier of (a) the close
of business on the tenth (10th) day (or such later day as may be determined by a
majority of the Board of Directors) after a person or group acquires beneficial
ownership of fifteen percent (15%) or more of the Company's Common Stock
(including Common Stock issuable upon conversion or exchange of any convertible
securities), and (b) the close of business on the tenth (10th) business day (or
such later day as may be determined by a majority of the Board of Directors)
after a person or group announces a tender or exchange offer, the consummation
of which would result in ownership by a person or group of fifteen percent (15%)
or more of the Company's Common Stock (including Common Stock issuable upon
conversion or exchange of any convertible securities).
 
INITIAL EXERCISE OF RIGHTS--PURCHASE OF CELLNET SERIES A PARTICIPATING PREFERRED
  STOCK
 
    The Rights may not be exercised prior to the Distribution Date. Following
the Distribution Date, each Right will entitle the holder to purchase for $50.00
(the "Exercise Price") one one-thousandth (1/1000) of a share of the Company's
Preferred Stock, subject to certain adjustments in both price and number of
shares.
 
FLIP-IN PROVISIONS--RIGHT TO BUY COMPANY COMMON STOCK
 
    Unless the Rights are earlier redeemed or have expired, if a person or group
acquires beneficial ownership of fifteen percent (15%) or more of the Company's
Common Stock (including Common Stock issuable upon conversion or exchange of any
convertible securities) (an "Acquiring Person"), then proper provision shall be
made by the Company's Board of Directors so that each Right (other than Rights
owned by an Acquiring Person or its affiliates) will entitle the holder thereof
to purchase, for the Exercise Price, a
<PAGE>
number of shares of the Company's Common Stock having a then current market
value of twice the Exercise Price.
 
FLIP-OVER PROVISIONS--RIGHT TO BUY ACQUIRING COMPANY COMMON STOCK
 
    Unless the Rights are earlier redeemed or have expired, if, after an
Acquiring Person acquires beneficial ownership of fifteen percent (15%) or more
of the Company's Common Stock (including Common Stock issuable upon conversion
or exchange of any convertible securities), (a) the Company merges into another
entity, (b) an acquiring entity merges into the Company, or (c) the Company
sells more than fifty percent (50%) of its assets or earning power, then each
Right (other than Rights owned by an Acquiring Person or its affiliates) will
entitle the holder thereof to purchase, for the Exercise Price, a number of
shares of the common stock of the person or entity engaging in the transaction
having a then current market value of twice the Exercise Price.
 
EXCHANGE PROVISIONS
 
    At any time after an Acquiring Person acquires beneficial ownership of
fifteen percent (15%) or more of the Company's Common Stock (including Common
Stock issuable upon conversion or exchange of any convertible securities) and
prior to the acquisition by the Acquiring Person of fifty percent (50%) of the
Company's Common Stock (including Common Stock issuable upon conversion or
exchange of any convertible securities), the Board of Directors may exchange the
Rights (other than Rights owned by the Acquiring Person or its affiliates), in
whole or in part, for shares of the Company's Common Stock at an exchange ratio
of one (1) share of Common Stock per Right (subject to certain adjustments).
 
REDEMPTION PROVISIONS
 
    The Rights are redeemable at the Company's option (with the approval of the
Board of Directors) at any time prior to the close of business on the day (prior
to the Expiration Date) of a public announcement that an Acquiring Person has
acquired beneficial ownership of fifteen percent (15%) or more of the Company's
Common Stock (including Common Stock issuable upon conversion or exchange of any
convertible securities). Upon exercise of the Company's option to redeem the
Rights, holders will be entitled to receive a redemption payment of $0.001 per
Right (subject to certain adjustments) payable in cash or in shares of the
Company's Common Stock.
 
EXPIRATION OF RIGHTS
 
    The Rights expire (the "Expiration Date") on the earliest of (a) November 24
, 2008, (b) the consummation of any of the following transactions--(i) the
Company merges into another entity, (ii) an acquiring entity merges into the
Company, or (iii) the Company sells more than fifty percent (50%) of its assets
or earning power, (c) the effective date of a redemption of the Rights
determined by the Board of Directors, and (d) the time at which the Board of
Directors orders an exchange of the Rights.
 
LIMITATIONS
 
    Under certain circumstances, Rights beneficially owned by an Acquiring
Person or an affiliate or associate of an Acquiring Person and any subsequent
holder of such Rights may become null and void.
 
AMENDMENTS AND RIGHTS AGREEMENT
 
    The terms of the Rights and the Rights Agreement (the "Rights Agreement")
dated November 24, 1998 between the Company and The Bank of New York as Rights
Agent may be amended in any respect without the consent of the Rights holders on
or prior to the date a person becomes an Acquiring Person. From and after the
Distribution Date, the terms of the Rights and the Rights Agreement may be
amended without the consent of the Rights holders in order to cure any
ambiguities or to make changes which do
 
                                       2
<PAGE>
not adversely affect the interests of Rights holders (other than an Acquiring
Person or an affiliate or associate of an Acquiring Person).
 
VOTING RIGHTS
 
    The Rights will have no voting rights.
 
ANTI-DILUTION PROVISIONS
 
    The Rights will have the benefits of certain customary anti-dilution
provisions.
 
TAXES
 
    The Rights distribution should not be taxable for Federal income tax
purposes. However, following an event which renders the Rights exercisable or
upon redemption of the Rights, stockholders may recognize taxable income.
 
THE FOREGOING IS A SUMMARY OF CERTAIN PRINCIPAL TERMS OF THE STOCKHOLDER RIGHTS
PLAN ONLY AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE DETAILED TERMS OF
THE RIGHTS AGREEMENT. A COPY OF THE RIGHTS AGREEMENT HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION ON FORM 8-A DATED DECEMBER 9, 1998 AND IS
AVAILABLE FREE OF CHARGE FROM THE COMPANY.
