Item 5. Other Events

          On November 4, 1998, the Board of Directors of True North
Communications Inc. (the "Company") declared a dividend distribution of one
Right for each outstanding share of the Company's common stock, $.33-1/3 par 
value per share ("Common Stock"), to stockholders of record at the close of
business on November 30, 1998. Each Right entitles the registered holder to
purchase from the Company a unit consisting of one two-thousandth of a share (a
"Unit") of Series B Junior Participating Preferred Stock, par value $1.00 per
share (the "Preferred Stock"), of the Company at a price of $100 per Unit (the
"Purchase Price"), subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") dated as of
November 4, 1998 between the Company and First Chicago Trust Company of New
York, as Rights Agent.

          Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
certificates will be distributed.  The Rights will separate from the Common
Stock and the Distribution Date will occur upon the earliest of (i) 10 days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 15% or more (or, in the case of Publicis
Communication, 22% or more) of the outstanding shares of Common Stock (the
"Stock Acquisition Date"), (ii) 10 business days (or such later date as may be
determined by action of the Board of Directors prior to such time as any person
or group becomes an Acquiring Person) following the commencement of a tender
offer or exchange offer which, if consummated, would result in a person or group
beneficially owning 15% or more (or, in the case of Publicis Communication, 22%
or more) of the outstanding shares of Common Stock or (iii) during any 180 Day
Period (as defined below), the date immediately following the date of execution
of an agreement relating to or providing for (x) an acquisition of the Company
in a merger or other business combination transaction in which the Company would
not be the surviving corporation, (y) an acquisition of the Company in a merger
or other business combination transaction in which the Company would be the
surviving corporation and in which all or part of the Common Stock would be
converted into securities of another entity, cash or other property, or (z) 50%
or more of the Company's assets or earning power being sold or transferred.

          Until the Distribution Date, (i) the Rights will be evidenced by the
Common Stock certificates and will be transferred with and only with such Common
Stock certificates, (ii) new Common Stock certificates issued on or after
November 30, 1998 will contain a notation incorporating the Rights Agreement by
reference and (iii) the surrender for transfer of any certificates for Common
Stock outstanding will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificate.

          Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the occurrence of a Triggering Event (as defined below) that,
upon any exercise of Rights, a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

                                      -2-
<PAGE>
 
          The Rights are not exercisable until the Distribution Date and will
expire at the close of business on November 30, 2008, unless earlier redeemed by
the Company as described below.

          As soon as practicable after the Distribution Date, Rights
certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and, thereafter, the separate Rights
certificates alone will represent the Rights.  Except as otherwise provided in
the Rights Agreement, only shares of Common Stock issued prior to the
Distribution Date will be issued with Rights.

          In the event that, at any time following the Distribution Date, a
person or group becomes an Acquiring Person, each holder of a Right will
thereafter have the right to receive, upon exercise, Common Stock having a value
equal to two times the exercise price of the Right. If an insufficient number of
shares of Common Stock is authorized for issuance, then the Board would be
required to substitute cash, property or other securities of the Company for the
Common Stock.  Notwithstanding any of the foregoing, following the occurrence of
the event set forth in this paragraph, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person will be null and void.  However, Rights are not exercisable
following the occurrence of the event set forth in this paragraph until such
time as the Rights are no longer redeemable by the Company as set forth below.

          For example, at an exercise price of $100 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following an event
set forth in the preceding paragraph would entitle its holder to purchase $200
worth of Common Stock (or other consideration, as noted above) for $100.
Assuming that the Common Stock had a per share value of $25 at such time, the
holder of each valid Right would be entitled to purchase eight shares of Common
Stock for $100.

          In the event that, at any time following the Stock Acquisition Date or
during the pendency of a 180 Day Period, (i) the Company is acquired in a merger
or other business combination transaction in which the Company is not the
surviving corporation, (ii) the Company is acquired in a merger or other
business combination transaction in which the Company is the surviving
corporation and all or part of the Common Stock is converted into securities of
another entity, cash or other property, or (iii) 50% or more of the Company's
assets or earning power is sold or transferred, each holder of a Right (except
Rights which previously have been voided as set forth above) shall thereafter
have the right to receive, upon exercise, common stock of the acquiring company
having a value equal to two times the exercise price of the Right.  The events
set forth in this paragraph and in the second preceding paragraph are referred
to as the "Triggering Events."

          The purchase price payable, and the number of Units of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) if holders of the Preferred Stock are granted certain
rights, options or warrants to subscribe for Preferred Stock or convertible
securities at less than

                                      -3-
<PAGE>
 
the current market price of the Preferred Stock, or (iii) upon the distribution
to holders of the Preferred Stock of evidences of indebtedness or assets
(excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

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

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

          In general, the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (subject to adjustment and payable in cash,
Common Stock or other consideration deemed appropriate by the Board of
Directors) at any time until ten days following the Stock Acquisition Date.
Immediately upon the action of the Board of Directors authorizing any
redemption, the Rights will terminate and the only right of the holders of
Rights will be to receive the redemption price.  Notwithstanding the foregoing,
in the event that a majority of the Board of Directors of the Company is elected
by stockholder action by written consent, or is comprised of persons elected at
a meeting of stockholders who were not nominated by the Board of Directors in
office immediately prior to such meeting, then for a period of one hundred
eighty (180) days following the effectiveness of such election (the "180 Day
Period"), the Rights may not be redeemed.

          Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.  While the distribution of the Rights will not
result in the recognition of taxable income by stockholders or the Company,
stockholders may, depending upon the circumstances, recognize taxable income
after a Triggering Event.

          The terms of the Rights may be amended by the Board of Directors of
the Company without the consent of the holders of the Rights, including an
amendment to lower certain thresholds described above to not less than the
greater of (i) the sum of .001% and the largest percentage of the outstanding
shares of Common Stock then known to the Company to be beneficially owned by any
person or group of affiliated or associated persons and (ii) 10%, except that
from and after such time as any person or group of affiliated or associated
persons becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights.  Notwithstanding the foregoing, during
the pendency of any 180 Day Period, the terms of the Rights may not be amended
other than to cure ambiguities or to correct defects or inconsistencies.

                                RIGHTS AGREEMENT
                                ----------------

          RIGHTS AGREEMENT, dated as of November 4, 1998 (this "Agreement"),
between True North Communications Inc., a Delaware corporation (the "Company"),
and First Chicago Trust Company of New York, a New York corporation (the "Rights
Agent").

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

          WHEREAS, on November 4, 1998 (the "Rights Dividend Declaration Date"),
the Board of Directors of the Company authorized and declared a dividend
distribution of one Right (as hereinafter defined) for each share of Common
Stock (as hereinafter defined) of the Company outstanding at the Close of
Business on November 30, 1998 (the "Record Date"), each Right initially
representing the right to purchase one two-thousandth of a share of Series B
Junior Participating Preferred Stock of the Company having the rights, powers
and preferences set forth in the form of Certificate of Designation attached
hereto as Exhibit A, upon the terms and subject to the conditions hereinafter
set forth (the "Rights"), and has further authorized the issuance of one Right
(as such number may hereinafter be adjusted pursuant to the provisions of
Section 11(p) hereof) for each share of Common Stock of the Company issued
between the Record Date and the earlier of the Distribution Date and the
Expiration Date (as such terms are hereinafter defined) or, in certain
circumstances provided in Section 22 hereof, after the Distribution Date;

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

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

          (a) "Acquiring Person" shall mean any Person who or which, together
     with all Affiliates and Associates of such Person, shall be the Beneficial
     Owner of 15% or more of the shares of Common Stock then outstanding, but
     shall not include (i) the Company, (ii) any Subsidiary of the Company,
     (iii) any employee benefit plan of the Company or of any Subsidiary of the
     Company, (iv) any Person organized, appointed or established by the Company
     for or pursuant to the terms of any such plan or (v) Publicis Communication
     or any Affiliate or Associate of Publicis Communication; provided, however,
     that if Publicis Communication becomes the Beneficial Owner of 22% or more
     of the outstanding shares of Common Stock of the Company, neither Publicis
     Communication nor any Affiliate or Associate of Publicis Communication
     shall be excluded from being an "Acquiring Person." Notwithstanding the
     foregoing, (x) no Person shall become an "Acquiring Person" as the result
     of an acquisition of shares of Common Stock by the Company which, by
     reducing the number of shares outstanding, increases the proportionate
     number of shares beneficially owned by such Person to 15% or more of the
     shares of Common Stock then outstanding; provided, however, that if a
     Person, other than those persons excepted in clauses (i), (ii), (iii) or
     (iv) of the preceding sentence, shall become the
<PAGE>
 
     Beneficial Owner of 15% or more of the shares of Common Stock then
     outstanding by reason of purchases of Common Stock by the Company and
     shall, after such purchases by the Company, become the Beneficial Owner of
     any additional shares of Common Stock, then such Person shall be deemed to
     be an "Acquiring Person", and (y) neither Publicis Communication nor any
     Affiliate or Associate of Publicis Communication shall become an "Acquiring
     Person" as the result of an acquisition of shares of Common Stock by the
     Company which, by reducing the number of shares outstanding, increases the
     proportionate number of shares beneficially owned by such Persons to 22% or
     more of the shares of Common Stock then outstanding; provided, however,
     that if such Persons shall become the Beneficial Owner of 22% or more of
     the shares of Common Stock then outstanding by reason of purchases of
     Common Stock by the Company and shall, after such purchases by the Company,
     become the Beneficial Owner of any additional shares of Common Stock, then
     Publicis Communication and any such Affiliate or Associate shall be deemed
     to be an "Acquiring Person".  Notwithstanding the foregoing, if the Board
     of Directors of the Company determines in good faith that a Person who
     would otherwise be an "Acquiring Person" (as defined pursuant to the
     foregoing provisions of this paragraph (a)) has become such inadvertently,
     and such Person divests as promptly as practicable a sufficient number of
     shares of Common Stock so that such Person would no longer be an "Acquiring
     Person" (as defined pursuant to the foregoing provisions of this paragraph
     (a)), then such Person shall not be deemed to be an "Acquiring Person" for
     any purposes of this Agreement.

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

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

          (d) A Person shall be deemed the "Beneficial Owner" of, and shall be
     deemed to "beneficially own," any securities:

                    (i)  which such Person or any of such Person's Affiliates or
          Associates, directly or indirectly, has the right to acquire (whether
          such right is exercisable immediately or only after the passage of
          time) pursuant to any agreement, arrangement or understanding (whether
          or not in writing) or upon the exercise of conversion rights, exchange
          rights, rights, warrants or options, or otherwise; provided, however,
          that a Person shall not be deemed the "Beneficial Owner" of, or to
          "beneficially own,"  (A) securities tendered pursuant to a tender or
          exchange offer made by such Person or any of such Person's Affiliates
          or Associates until such tendered securities are accepted for purchase
          or exchange, or (B) securities issuable upon exercise of Rights at any

                                      -2-
<PAGE>
 
          time prior to the occurrence of a Triggering Event, or (C) securities
          issuable upon exercise of Rights from and after the occurrence of a
          Triggering Event which Rights were acquired by such Person or any such
          Person's Affiliates or Associates prior to the Distribution Date or
          pursuant to Section 3(a) or Section 22 hereof (the "Original Rights")
          or pursuant to Section 11(i) hereof in connection with an adjustment
          made with respect to any Original Rights;

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

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

provided, however, that nothing in this paragraph (d) shall cause a Person

expiration of forty days after the date of such acquisition.

           Section 3.    Issue of Rights Certificates.

          (a) Until the earliest of (i) the Close of Business on the tenth day
after the Stock Acquisition Date (or, if the tenth day after the Stock
Acquisition Date occurs before the Record Date, the Close of Business on the
Record Date), (ii) the Close of Business on the tenth Business Day (or such
later date as may be determined by action of the Board of Directors of the
Company prior to such time as any Person becomes an Acquiring Person) after the
date that a tender or exchange offer by any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company, or any Person organized, appointed or established by
the Company for or pursuant to the terms of any such plan) is first published or
sent or given within the meaning of Rule 14d-2(a) of the General Rules and
Regulations under the Exchange Act, if upon consummation thereof, such Person
would be the Beneficial Owner of 15% or more, or, in the case of Publicis
Communication or any Affiliate or Associate of Publicis Communication, 22% or
more, of the shares of Common Stock then outstanding, or (iii) the date
immediately following the date of execution of an agreement relating to or
providing for a transaction constituting a Section 13 Event (including any such
date which is after the date of this Agreement and prior to the issuance of the
Rights; the earliest of the dates referred to in clauses (i), (ii) and (iii)
being herein referred to as the "Distribution Date"), (x) the Rights will be
evidenced (subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock registered in the names of the holders of the
Common Stock (which certificates for Common Stock shall be deemed also to be
certificates for Rights) and not by separate certificates and (y) the Rights
will be

                                      -5-
<PAGE>
 
transferable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company).  As soon as practicable
after the Distribution Date, the Rights Agent will send by first-class, insured,
postage prepaid mail, to each record holder of the Common Stock as of the Close
of Business on the Distribution Date, at the address of such holder shown on the
records of the Company, one or more Rights certificates, in substantially the
form of Exhibit B hereto (the "Rights Certificates"), evidencing one Right for
each share of Common Stock so held, subject to adjustment as provided herein,
along with a copy of a Summary of Rights to Purchase Preferred Stock, in
substantially the form attached hereto as Exhibit C (the "Summary of Rights").
In the event that an adjustment in the number of Rights per share of Common
Stock has been made pursuant to Section 11(p) hereof, at the time of
distribution of the Rights Certificates, the Company shall make the necessary
and appropriate rounding adjustments (in accordance with Section 14(a) hereof)
so that Rights Certificates representing only whole numbers of Rights are
distributed and cash is paid in lieu of any fractional Rights.  As of and after
the Distribution Date, the Rights will be evidenced solely by such Rights
Certificates.

          (b) With respect to certificates for the Common Stock outstanding as
of the Record Date, until the Distribution Date, the Rights will be evidenced by
such certificates for the Common Stock registered in the names of the holders
thereof.   Until the earlier of the Distribution Date or the Expiration Date,
the surrender for transfer of any certificate representing shares of Common
Stock in respect of which Rights have been issued, with or without a copy of the
Summary of Rights attached thereto, shall also constitute the transfer of the
Rights associated with such shares of Common Stock.

          (c) Rights shall be issued in respect of all shares of Common Stock
which are issued (whether originally issued or from the Company's treasury)
after the Record Date but prior to the earlier of the Distribution Date or the
Expiration Date or, in certain circumstances provided in Section 22 hereof,
after the Distribution Date.  Certificates representing such shares of Common
Stock shall also be deemed to be certificates for Rights, and shall bear a
legend substantially in the following form:

          This certificate also evidences and entitles the holder hereof to
     certain rights as set forth in the Rights Agreement between True North
     Communications Inc. (the "Company") and First Chicago Trust Company of New
     York (the "Rights Agent") dated as of November 4, 1998 (the "Rights
     Agreement"), the terms of which are hereby incorporated herein by reference
     and a copy of which is on file at the principal offices of the Company.
     Under certain circumstances, as set forth in the Rights Agreement, such
     Rights will be evidenced by separate certificates and will no longer be
     evidenced by this certificate.  The Company will mail to the holder of this
     certificate a copy of the Rights Agreement, as in effect on the date of
     mailing, without charge, promptly after receipt of a written request
     therefor.  Under certain circumstances set forth in the Rights Agreement,
     Rights issued to, or held by, any Person who is, was or becomes an
     Acquiring Person or any Affiliate or Associate thereof (as such terms are
     defined in the Rights Agreement), whether currently held

                                      -6-
<PAGE>
 
     by or on behalf of such Person or by any subsequent holder, may become null
     and void.

With respect to such certificates containing the foregoing legend, until the
earlier of (i) the Distribution Date or (ii) the Expiration Date, the Rights
associated with the Common Stock represented by such certificates shall be
evidenced by such certificates alone and registered holders of Common Stock
shall also be the registered holders of the associated Rights, and the surrender
for transfer of any of such certificates shall also constitute the transfer of
the Rights associated with the Common Stock represented by such certificates.
In the event the Company purchases or acquires any shares of its Common Stock
after the Record Date but prior to the Distribution Date, any Rights associated
with such shares shall be deemed cancelled and retired so that the Company shall
not be entitled to exercise any Rights associated with shares of Common Stock
that are not outstanding.

           Section 4.    Form of Rights Certificates.

          (a) The Rights Certificates (and the forms of election to purchase and
of assignment to be printed on the reverse thereof) shall each be substantially
in the form set forth in Exhibit B hereto and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange on which the Rights may from time to
time be listed, or to conform to usage. Subject to the provisions of Section 11
and Section 22 hereof, the Rights Certificates, whenever distributed, shall be
dated as of the Record Date or, in the case of Rights with respect to shares of
Common Stock issued or becoming outstanding after the Record Date, the same date
as the date of the stock certificate evidencing such shares, and on their face
shall entitle the holders thereof to purchase such number of one two-thousandths
of a share of Preferred Stock as shall be set forth therein at the price set
forth therein (such exercise price per one two-thousandths of a share, the
"Purchase Price"), but the amount and type of securities purchasable upon the
exercise of each Right and the Purchase Price thereof shall be subject to
adjustment from time to time as provided in Sections 11 and 13(a) hereof.

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

                                      -7-
<PAGE>
 
Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon
transfer, exchange, replacement or adjustment of any other Rights Certificate
referred to in this sentence, shall contain (to the extent feasible) the
following legend:

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

           Section 5.    Countersignature and Registration.

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

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

          Section 6.     Transfer, Split Up, Combination and Exchange of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.  (a)
Subject to the provisions of Section 4(b), Section 7(e) and Section 14 hereof,
at any time after the Close of Business on the Distribution Date, and at or
prior to the Close of Business on the Expiration Date, any Rights Certificate or
Certificates (other than Rights Certificates representing Rights that have
become void pursuant to Section 7(e) or that have been exchanged pursuant to
Section 24 hereof) may be transferred, split up, combined or exchanged for
another Rights Certificate or Certificates, entitling the registered holder to
purchase a like number of one two thousandths of a share of Preferred Stock (or,
following a

                                      -8-
<PAGE>
 
Triggering Event, Common Stock, other securities, cash or other assets, as the
case may be) as the Rights Certificate or Certificates surrendered then entitled
such holder (or former holder in the case of a transfer) to purchase.  Any
registered holder desiring to transfer, split up, combine or exchange any Rights
Certificate or Certificates shall make such request in writing delivered to the
Rights Agent, and shall surrender the Rights Certificate or Certificates to be
transferred, split up, combined or exchanged at the principal office or offices
of the Rights Agent designated for such purpose.  Neither the Rights Agent nor
the Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered Rights Certificate until the registered holder
shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request.  Thereupon the Rights Agent shall, subject to Section
4(b), Section 7(e), Section 14 and Section 24 hereof, countersign and deliver to
the Person entitled thereto a Rights Certificate or Rights Certificates, as the
case may be, as so requested.  The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Rights
Certificates.

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

          Section 7.     Exercise of Rights; Purchase Price; Expiration Date of
Rights.  (a) Subject to Section 7(e) hereof, the registered holder of any Rights
Certificate may exercise the Rights evidenced thereby (except as otherwise
provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly executed, to the Rights Agent
at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price with respect to
the total number of one two thousandths of a share of Preferred Stock (or other
securities, cash or other assets, as the case may be) as to which such
surrendered Rights are then exercisable, at or prior to the earliest of (i) the
Close of Business on November 30, 2008 (the "Final Expiration Date"), (ii) the
time at which the Rights are redeemed as provided in Section 23 hereof or (iii)
the time at which such Rights are exchanged pursuant to Section 24 hereof (the
earliest of (i), (ii) and (iii) being herein referred to as the "Expiration
Date").

          (b) The Purchase Price for each one two thousandth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $100, and
shall be subject to adjustment from time

                                      -9-
<PAGE>
 
to time as provided in Sections 11 and 13(a) hereof and shall be payable in
accordance with paragraph (c) below.

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per one two-thousandth of a share of Preferred Stock (or other shares,
securities, cash or other assets, as the case may be) to be purchased as set
forth below and an amount equal to any applicable transfer tax (as determined by
the Rights Agent) required to be paid by the holder of the Rights Certificate in
accordance with Section 9 hereof, the Rights Agent shall, subject to Section
20(k) hereof, thereupon promptly (i) (A) requisition from any transfer agent of
the shares of Preferred Stock (or make available, if the Rights Agent is the
transfer agent for such shares) certificates for the total number of one two-
thousandths of a share of Preferred Stock to be purchased, and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests, or (B) if the Company shall have elected to deposit the total number
of shares of Preferred Stock issuable upon exercise of the Rights hereunder with
a depositary agent, requisition from the depositary agent depositary receipts
representing such number of one two-thousandths of a share of Preferred Stock as
are to be purchased (in which case certificates for the shares of Preferred
Stock represented by such receipts shall be deposited by the transfer agent with
the depositary agent) and the Company will direct the depositary agent to comply
with such request, (ii) requisition from the Company the amount of cash, if any,
to be paid in lieu of fractional shares in accordance with Section 14 hereof,
(iii) after receipt of such certificates or depositary receipts, cause the same
to be delivered to or upon the order of the registered holder of such Rights
Certificate, registered in such name or names as may be designated by such
holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon
the order of the registered holder of such Rights Certificate.  The payment of
the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)
hereof) shall be made in cash or by certified bank check or bank draft payable
to the order of the Company. In the event that the Company is obligated to issue
other securities (including Common Stock) of the Company, pay cash and/or
distribute other property pursuant to Section 11(a) hereof, the Company will
make all arrangements necessary so that such other securities, cash and/or other
property are available for distribution by the Rights Agent, if and when
appropriate.  The Company reserves the right to require prior to the occurrence
of a Triggering Event that, upon any exercise of Rights, a number of Rights be
exercised so that only whole shares of Preferred Stock would be issued.

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

          (e) Notwithstanding anything in this Agreement to the contrary, from
and after the first occurrence of a Section 11(a) (ii) Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes

                                      -10-
<PAGE>
 
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 (or any Affiliate
or Associate thereof) to holders of equity interests in such Acquiring Person
(or any Affiliate or Associate thereof) or to any Person with whom the Acquiring
Person (or any Affiliate or Associate thereof) has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which the Board of Directors of the Company has determined is part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of this Section 7(e), shall become null and void without any further
action and no holder of such Rights shall have any rights whatsoever with
respect to such Rights, whether under any provision of this Agreement or
otherwise.  The Company shall use all reasonable efforts to ensure that the
provisions of this Section 7(e) and Section 4(b) hereof are complied with, but
shall have no liability to any holder of Rights Certificates or other Person as
a result of its failure to make any determinations with respect to an Acquiring
Person or any of its Affiliates, Associates or transferees hereunder.

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

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

          Section 9.     Reservation and Availability of Capital Stock.  (a)
The Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued shares of Preferred Stock (and,
following the occurrence of a Triggering Event, out of its authorized and
unissued shares of Common Stock and/or other securities or out of its authorized
and issued shares held in its treasury), the number of shares of Preferred Stock
(and, following the occurrence of a Triggering Event, Common Stock and/or other
securities) that, as provided in this

                                      -11-
<PAGE>
 
Agreement, including Section 11(a)(iii) hereof, will be sufficient to permit the
exercise in full of all outstanding Rights.

          (b) So long as the shares of Preferred Stock (and, following the
occurrence of a Triggering Event, Common Stock and/or other securities) issuable
and deliverable upon the exercise of the Rights may be listed on any national
securities exchange or the Nasdaq National Market, 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
or the Nasdaq National Market upon official notice of issuance upon such
exercise.

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

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

          (e) The Company further covenants and agrees that it will pay, when
due and payable, any and all federal and state transfer taxes and charges which
may be payable in respect of

                                      -12-
<PAGE>
 
the issuance or delivery of the Rights Certificates and of any certificates for
a number of one two-thousandths of a share of Preferred Stock (or Common Stock
and/or other securities, as the case may be) upon the exercise of Rights.  The
Company shall not, however, be required to pay any transfer tax which may be
payable in respect of any transfer or delivery of Rights Certificates to a
Person other than, or the issuance or delivery of a number of one two-
thousandths of a share of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in respect of a name other than that of, the
registered holder of the Rights Certificates evidencing Rights surrendered for
exercise or to issue or deliver any certificates for a number of one two-
thousandths of a share of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until such tax shall have been paid (any
such tax being payable by the holder of such Rights Certificate at the time of
surrender) or until it has been established to the Company's satisfaction that
no such tax is due.

          Section 10.    Preferred Stock Record Date.  Each person in whose name
any certificate for a number of one two-thousandths of a share of Preferred
Stock (or Common Stock and/or other securities, as the case may be) is issued
upon the exercise of Rights shall for all purposes be deemed to have become the
holder of record of such fractional shares of Preferred Stock (or Common Stock
and/or other securities, as the case may be) represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares (fractional or otherwise) on, and such certificate shall be
dated, the next succeeding Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are open.  Prior to the exercise of the Rights evidenced thereby, the holder of
a Rights Certificate shall not be entitled to any rights of a stockholder of the
Company with respect to shares or other securities for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

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

          (a)(i)  In the event the Company shall at any time after the date of
     this Agreement (A) declare a dividend on the Preferred Stock payable in
     shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock,
     (C) combine the outstanding Preferred Stock into a smaller number of
     shares, or (D) issue any shares of its capital stock in a reclassification
     of the Preferred Stock (including any such reclassification in connection
     with a consolidation or merger in which the Company is the continuing or
     surviving corporation), except as otherwise provided in this Section 11(a)
     and Section 7(e) hereof, the Purchase Price in effect at the time of the

                                      -13-
<PAGE>
 
     record date for such dividend or of the effective date of such subdivision,
     combination or reclassification, and the number and kind of shares of
     Preferred Stock or capital stock, as the case may be, issuable on such
     date, shall be proportionately adjusted so that the holder of any Right
     exercised after such time shall be entitled to receive, upon payment of the
     Purchase Price then in effect, the aggregate number and kind of shares of
     Preferred Stock or capital stock, as the case may be, which, if such Right
     had been exercised immediately prior to such date and at a time when the
     Preferred Stock transfer books of the Company were open, such holder would
     have owned upon such exercise and been entitled to receive by virtue of
     such dividend, subdivision, combination or reclassification.  If an event
     occurs which would require an adjustment under both this Section 11(a)(i)
     and Section 11(a)(ii) hereof, the adjustment provided for in this Section
     11(a)(i) shall be in addition to, and shall be made prior to, any
     adjustment required pursuant to Section 11(a)(ii) hereof.

          (ii) Subject to Section 24 hereof, in the event any Person becomes an
     Acquiring Person, then each holder of a Right (except as provided below and
     in Section 7(e) hereof) shall thereafter have the right to receive, upon
     exercise thereof, at a price equal to the then current Purchase Price in
     accordance with the terms of this Agreement, in lieu of a number of one
     two-thousandths of a share of Preferred Stock, such number of shares of
     Common Stock of the Company as shall equal the result obtained by (x)
     multiplying the then current Purchase Price by the then number of one two-
     thousandths of a share of Preferred Stock for which a Right was exercisable
     immediately prior to the first occurrence of a Section 11(a)(ii) Event and
     (y) dividing that product (which, following such first occurrence shall
     thereafter be referred to as the "Purchase Price" for each Right and for
     all purposes of this Agreement) by 50% of the current market price
     (determined pursuant to Section 11(d) hereof) per share of Common Stock on
     the date of such first occurrence (such number of shares, the "Adjustment
     Shares").

          (iii) In the event that the number of shares of Common Stock which is
     authorized by the Company's certificate of incorporation, as amended, but
     not outstanding or reserved for issuance for purposes other than upon
     exercise of the Rights, is not sufficient to permit the exercise in full of
     the Rights in accordance with the foregoing subparagraph (ii) of this
     Section 11(a), the Company shall: (A) determine the excess of (1) the
     value of the Adjustment Shares issuable upon the exercise of a Right (the
     "Current Value") over (2) the Purchase Price (such excess, the "Spread"),
     and (B) with respect to each Right, make adequate provision to substitute
     for the Adjustment Shares, upon payment of the applicable Purchase Price,
     (1) cash, (2) a reduction in the Purchase Price, (3) Common Stock or other
     equity securities of the Company (including, without limitation, shares, or
     units of shares, of preferred stock, such as the Preferred Stock, which the
     Board of Directors of the Company has deemed to have substantially the same
     value or economic rights as shares of Common Stock (such shares or units of
     shares of preferred stock, "common

                                      -14-
<PAGE>
 
     stock equivalents")), (4) debt securities of the Company, (5) other assets,
     or (6) any combination of the foregoing, having an aggregate value equal to
     the Current Value (less the amount of any reduction in the Purchase Price),
     where such aggregate value has been determined by the Board of Directors of
     the Company based upon the advice of a nationally recognized investment
     banking firm selected by the Board of Directors of the Company; provided,
     however, that if the Company shall not have made adequate provision to
     deliver value pursuant to clause (B) above within thirty (30) days
     following the later of (x) the first occurrence of a Section 11(a)(ii)
     Event and (y) the date on which the Company's right of redemption pursuant
     to Section 23(a) expires (the later of (x) and (y) being referred to herein
     as the "Section 11(a)(ii) Trigger Date"), then the Company shall be
     obligated to deliver, upon the surrender for exercise of a Right and
     without requiring payment of the Purchase Price, shares of Common Stock (to
     the extent available) and then, if necessary, cash, which shares and/or
     cash have an aggregate value equal to the Spread.  If the Board of
     Directors of the Company shall determine in good faith that it is likely
     that sufficient additional shares of Common Stock could be authorized for
     issuance upon exercise in full of the Rights, the thirty (30) day period
     set forth above may be extended to the extent necessary, but not more than
     ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that
     the Company may seek stockholder approval for the authorization of such
     additional shares (such thirty (30) day period, as it may be extended, the
     "Substitution Period").  To the extent that the Company determines that
     action should 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 such stockholder
     approval for such authorization of additional shares and/or to decide the
     appropriate form of distribution to be made pursuant to such first sentence
     and to determine the value thereof.  In the event of any such suspension,
     the Company shall issue a public announcement stating that the
     exercisability of the Rights has been temporarily suspended, as well as a
     public announcement at such time as the suspension is no longer in effect.
     For purposes of this Section 11(a)(iii), the value of each Adjustment Share
     shall be the current market price (as determined pursuant to Section 11(d)
     hereof) per share of Common Stock on the Section 11(a)(ii) Trigger Date and
     the value of any "common stock equivalent" shall be deemed to equal the
     current market price per share of the Common Stock on such date.

          (b) In case the Company shall fix a record date for the issuance of
     rights (other than the Rights), options or warrants to all holders of
     Preferred Stock entitling them to subscribe for or purchase (for a period
     expiring within forty-five (45) calendar days after such record date)
     Preferred Stock (or shares having the same rights, privileges and
     preferences as the shares of Preferred Stock ("equivalent preferred
     stock")) or securities convertible into Preferred Stock or equivalent
     preferred stock at a price per share of Preferred Stock or per share of
     equivalent preferred stock (or

                                      -15-
<PAGE>
 
     having a conversion price per share, if a security convertible into
     Preferred Stock or equivalent preferred stock) less than the current market
     price (as determined pursuant to Section 11(d) hereof) per share of
     Preferred Stock on such record date, the Purchase Price to be in effect
     after such record date shall be determined by multiplying the Purchase
     Price in effect immediately prior to such record date by a fraction, the
     numerator of which shall be the number of shares of Preferred Stock
     outstanding on such record date, plus the number of shares of Preferred
     Stock which the aggregate offering price of the total number of shares of
     Preferred Stock and/or equivalent preferred stock so to be offered (and/or
     the aggregate initial conversion price of the convertible securities so to
     be offered) would purchase at such current market price, and the
     denominator of which shall be the number of shares of Preferred Stock
     outstanding on such record date, plus the number of additional shares of
     Preferred Stock and/or equivalent preferred stock to be offered for
     subscription or purchase (or into which the convertible securities so to be
     offered are initially convertible).  In case such subscription price may be
     paid by delivery of consideration part or all of which may be in a form
     other than cash, the value of such consideration shall be as determined in
     good faith by the Board of Directors of the Company, whose determination
     shall be described in a statement filed with the Rights Agent and shall be
     binding on the Rights Agent and the holders of the Rights.  Shares of
     Preferred Stock owned by or held for the account of the Company shall not
     be deemed outstanding for the purpose of any such computation.  Such
     adjustment shall be made successively whenever such a record date is fixed,
     and in the event that such rights, options or warrants are not so issued,
     the Purchase Price shall be adjusted to be the Purchase Price which would
     then be in effect if such record date had not been fixed.

          (c) In case the Company shall fix a record date for a distribution to
     all holders of Preferred Stock (including any such distribution made in
     connection with a consolidation or merger in which the Company is the
     continuing corporation) of evidences of indebtedness, cash (other than a
     regular quarterly cash dividend out of the earnings or retained earnings of
     the Company), assets (other than a dividend payable in Preferred Stock, but
     including any dividend payable in stock other than Preferred Stock) or
     subscription rights or warrants (excluding those referred to in Section
     11(b) hereof), the Purchase Price to be in effect after such record date
     shall be determined by multiplying the Purchase Price in effect immediately
     prior to such record date by a fraction, the numerator of which shall be
     the current market price (as determined pursuant to Section 11(d) hereof)
     per share of Preferred Stock on such record date, less the fair market
     value (as determined in good faith by the Board of Directors of the
     Company, whose determination shall be described in a statement filed with
     the Rights Agent and shall be binding on the Rights Agent and the holders
     of the Rights) of the portion of the cash, assets or evidences of
     indebtedness so to be distributed or of such subscription rights or
     warrants applicable to a share of Preferred Stock and the denominator of
     which shall be such current market price (as determined pursuant to Section
     11(d) hereof) per share of Preferred Stock.  Such adjustments

                                      -16-
<PAGE>
 
     shall be made successively whenever such a record date is fixed, and in the
     event that such distribution is not so made, the Purchase Price shall be
     adjusted to be the Purchase Price which would have been in effect if such
     record date had not been fixed.

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

                                      -17-
<PAGE>
 
     The term "Trading Day" shall mean a day on which the principal national
     securities exchange on which the shares of Common Stock are listed or
     admitted to trading is open for the transaction of business or, if the
     shares of Common Stock are not listed or admitted to trading on any
     national securities exchange, a Business Day.  If the Common Stock is not
     publicly held or not so listed or traded, "current market price" per share
     shall mean the fair value per share as determined in good faith by the
     Board of Directors of the Company, whose determination shall be described
     in a statement filed with the Rights Agent and shall be conclusive for all
     purposes.

          (ii) For the purpose of any computation hereunder, the "current market
     price" per share of Preferred Stock shall be determined in the same manner
     as set forth above for the Common Stock in clause (i) of this Section 11(d)
     (other than the last sentence thereof).  If the current market price per
     share of Preferred Stock cannot be determined in the manner provided above,
     or if the Preferred Stock is not publicly held or listed or traded in a
     manner described in clause (i) of this Section 11 (d), the "current market
     price" per share of Preferred Stock shall be conclusively deemed to be an
     amount equal to 2,000 (as such number may be appropriately adjusted for
     such events as stock splits, stock dividends and recapitalizations with
     respect to the Common Stock occurring after the date of this Agreement)
     multiplied by the current market price per share of the Common Stock.  If
     neither the Common Stock nor the Preferred Stock is publicly held or so
     listed or traded, "current market price" per share of the Preferred Stock
     shall mean the fair value per share as determined in good faith by the
     Board of Directors of the Company, whose determination shall be described
     in a statement filed with the Rights Agent and shall be binding on the
     Rights Agent and the holders of the Rights.  For all purposes of this
     Agreement, the "current market price" of one two-thousandth of a share of
     Preferred Stock shall be equal to the "current market price" of one share
     of Preferred Stock divided by 2,000.

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

          (f) If as a result of an adjustment made pursuant to Section 11(a)(ii)
     or Section 13(a) hereof, the holder of any Right thereafter exercised shall
     become entitled to receive any shares of capital stock other than Preferred
     Stock, thereafter

                                      -18-
<PAGE>
 
     the number of such other shares so receivable upon exercise of any Right
     and the Purchase Price thereof shall be subject to adjustment from time to
     time in a manner and on terms as nearly equivalent as practicable to the
     provisions with respect to the Preferred Stock contained in Sections 11(a),
     (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the provisions of
     Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock
     shall apply on like terms to any such other shares.

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

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

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

                                      -19-
<PAGE>
 
     subject to Section 14 hereof, the additional Rights to which such holders
     shall be entitled as a result of such adjustment, or, at the option of the
     Company, shall cause to be distributed to such holders of record in
     substitution and replacement for the Rights Certificates held by such
     holders prior to the date of adjustment, and upon surrender thereof, if
     required by the Company, new Rights Certificates evidencing all the Rights
     to which such holders shall be entitled after such adjustment.  Rights
     Certificates so to be distributed shall be issued, executed and
     countersigned in the manner provided for herein (and may bear, at the
     option of the Company, the adjusted Purchase Price) and shall be registered
     in the names of the holders of record of Rights Certificates on the record
     date specified in the public announcement.

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

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

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

          (m) Anything in this Section 11 to the contrary notwithstanding, the
     Company shall be entitled to make such reductions in the Purchase Price, in
     addition to those adjustments expressly required by this Section 11, as and
     to the extent that the Board of Directors of the Company, in its good faith
     judgment, shall determine to be advisable in order that any (i)
     consolidation or subdivision of the Preferred

                                      -20-
<PAGE>
 
     Stock, (ii) issuance wholly for cash of any shares of Preferred Stock at
     less than the current market price, (iii) issuance wholly for cash of
     shares of Preferred Stock or securities which by their terms are
     convertible into or exchangeable for shares of Preferred Stock, (iv) stock
     dividends or (v) issuance of rights, options or warrants referred to in
     this Section 11, hereafter made by the Company to holders of its Preferred
     Stock shall not be taxable to such stockholders.

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

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

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

                                      -21-
<PAGE>
 
     Stock outstanding immediately prior to the occurrence of the event and the
     denominator of which shall be the total number of shares of Common Stock
     outstanding immediately following the occurrence of such event.

          Section 12.    Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or Section 13
hereof, the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Common Stock, a copy of such certificate, and (c) mail a
brief summary thereof to each holder of a Rights Certificate (or, if prior to
the Distribution Date, to each holder of a certificate representing shares of
Common Stock) in accordance with Section 26 hereof. The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained and shall not be deemed to have knowledge of 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 the Stock Acquisition Date or during
the pendency of a 180 Day Period, directly or indirectly, (x) the Company shall
consolidate with, or merge with and into, any other Person (other than a
Subsidiary of the Company in a transaction which complies with Section 11(o)
hereof), and the Company shall not be the continuing or surviving corporation of
such consolidation or merger, (y) any Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) hereof) shall
consolidate with, or merge with or into, the Company, and the Company shall be
the continuing or surviving corporation of such consolidation or merger and, in
connection with such consolidation or merger, all or part of the outstanding
shares of Common Stock shall be changed into or exchanged for stock or other
securities of any other Person or cash or any other property, or (z) the Company
shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell
or otherwise transfer), in one transaction or a series of related transactions,
assets or earning power aggregating more than 50% of the assets or earning power
of the Company and its Subsidiaries (taken as a whole) to any Person or Persons
(other than the Company or any Subsidiary of the Company in one or more
transactions each of which complies with Section 11(o) hereof) (any event
described in clauses (x), (y) or (z) of this Section 13(a) following the Stock
Acquisition Date or during the pendency of a 180 Day Period, a "Section 13
Event"), then, and in each such case, proper provision shall be made so that:
(i) each holder of a Right, except as provided in Section 7(e) hereof, shall
thereafter have the right to receive upon the exercise thereof at the then
current Purchase Price in accordance with the terms of this Agreement, in lieu
of a number of one two-thousandths of a share of Preferred Stock, such number of
validly authorized and issued, fully paid, nonassessable and freely tradeable
shares of Common Stock of the Principal Party (as such term is hereinafter
defined), not subject to any liens, encumbrances, rights of first refusal or
other adverse claims, as shall be equal to the result obtained by (l)
multiplying the then current Purchase Price by the number of one two-thousandths
of a share of Preferred Stock for which a Right is exercisable immediately prior
to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event
has occurred prior to the first occurrence of a Section 13 Event, multiplying
the number of

                                      -22-
<PAGE>
 
such one two-thousandths of a share of Preferred Stock for which a Right was
exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event by the Purchase Price in effect immediately prior to such first
occurrence), and (2) dividing that product (which, following the first
occurrence of a Section 13 Event, shall be referred to as the "Purchase Price"
for each Right and for all purposes of this Agreement) by 50% of the current
market price (determined pursuant to Section 11(d)(i) hereof) per share of the
Common Stock of such Principal Party on the date of consummation of such Section
13 Event; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such Section 13 Event, all the obligations and duties of
the Company pursuant to this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of Section 11 hereof shall apply only to such
Principal Party following the first occurrence of a Section 13 Event; (iv) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of shares of its Common Stock) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof shall thereafter be applicable, as nearly as reasonably
may be, in relation to its shares of Common Stock thereafter deliverable upon
the exercise of the Rights; and (v) the provisions of Section 11(a)(ii) hereof
shall be of no effect following the first occurrence of any Section 13 Event.

          (b)  "Principal Party" shall mean:

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

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

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

          (c) The Company shall not consummate any such consolidation, merger,
sale or transfer unless the Principal Party shall have a sufficient number of
authorized shares of its Common Stock which have not been issued or reserved for
issuance to permit the exercise in full of the Rights

                                      -23-
<PAGE>
 
in accordance with this Section 13 and unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing for the terms set forth in paragraphs (a) and
(b) of this Section 13 and further providing that, as soon as practicable after
the date of any consolidation, merger, sale or transfer of assets mentioned in
paragraph (a) of this Section 13, the Principal Party will:

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

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

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

          (d) The Company covenants and agrees not to consummate a transaction
constituting a Section 13 Event unless a Distribution Date shall have occurred
as a result of the actions described in clauses (i), (ii) or (iii) of Section
3(a) hereof.

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

          Section 14.    Fractional Rights and Fractional Shares.

          (a) The Company shall not be required to issue fractions of Rights,
except prior to the Distribution Date as provided in Section 11(p) hereof, or to
distribute Rights Certificates which evidence fractional Rights.  In lieu of
such fractional Rights, 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 purposes of this Section 14(a), the current market
value of a whole Right shall be the closing price of the Rights for the Trading
Day immediately prior to the date on which such fractional Rights would have
been otherwise issuable.  The closing price of the Rights for any day shall be
the last sale price, regular way, or, in case no such sale takes place on such
day, the average of the closing bid and asked prices, regular way, in either
case as reported in the principal consolidated transaction reporting system with
respect to securities listed or admitted to trading on the New York Stock
Exchange or,

                                      -24-
<PAGE>
 
if the Rights are not listed or admitted to trading on the New York Stock
Exchange, as reported to the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Rights are listed or admitted to trading, or if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by Nasdaq or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the Company.  If on any such date no such market maker is making a
market in the Rights the fair value of the Rights on such date as determined in
good faith by the Board of Directors of the Company shall be used.

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

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

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

                                      -25-

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

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

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

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

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

          (d) notwithstanding anything in this Agreement to the contrary,
     neither the Company nor the Rights Agent shall have any liability to any
     holder of a Right or other Person as a result of its inability to perform
     any of its obligations under this Agreement by reason of any preliminary or
     permanent injunction or other order, decree or ruling issued by a court of
     competent jurisdiction or by a governmental,

                                      -26-
<PAGE>
 
     regulatory or administrative agency or commission, or any statute, rule,
     regulation or executive order promulgated or enacted by any governmental
     authority, prohibiting or otherwise restraining performance of such
     obligation; provided, however, that the Company must use commercially
     reasonable efforts to have any such order, decree or ruling lifted or
     otherwise overturned as soon as possible.

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

          Section 18.    Concerning the Rights Agent.

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

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

          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

                                      -27-
<PAGE>
 
or consolidation to which the Rights Agent or any successor Rights Agent shall
be a party, or any corporation succeeding to the corporate trust or stock
transfer business of the Rights Agent or any successor Rights Agent, shall be
the successor to the Rights Agent under this Agreement without the execution or
filing of any paper or any further act on the part of any of the parties hereto;
provided, however, that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof.  In case at
the time such successor Rights Agent shall succeed to the agency created by this
Agreement, any of the Rights Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of a
predecessor Rights Agent and deliver such Rights Certificates so countersigned;
and in case at that time any of the Rights Certificates shall not have been
countersigned, any successor Rights Agent may countersign such Rights
Certificates either in the name of the predecessor or in the name of the
successor Rights Agent; and in all such cases such Rights Certificates shall
have the full force provided in the Rights Certificates and in this Agreement.

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

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

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

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

                                      -28-

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

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

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

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

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

          (h) The Rights Agent and any stockholder, director, officer or
     employee of the Rights Agent may buy, sell or deal in any of the Rights or
     other securities of the Company or become pecuniarily interested in any
     transaction in which the Company

                                      -29-
<PAGE>
 
     may be interested, or contract with or lend money to the Company or
     otherwise act as fully and freely as though it were not Rights Agent under
     this Agreement.  Nothing herein shall preclude the Rights Agent from acting
     in any other capacity for the Company or for any other legal entity.

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

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

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

          Section 21.    Change of Rights Agent.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Company, and to
each transfer agent of the Common Stock and Preferred Stock, by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail.  The Company may remove the Rights Agent or any successor Rights Agent
upon thirty (30) days' notice in writing, mailed to the Rights Agent or
successor Rights Agent, as the case may be, and to each transfer agent of the
Common Stock and Preferred Stock, by registered or certified mail, and 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 such
holder's Rights Certificate for inspection by the Company), then any registered
holder of any Rights Certificate may apply to any court of competent
jurisdiction for the appointment of a new Rights Agent.  Any successor Rights
Agent, whether appointed by the Company or by such a court, shall be (a) a
corporation organized and doing business under the laws of the United States or
of the State of Illinois or the State of New York (or of any

                                      -30-
<PAGE>
 
other state of the United States so long as such corporation is authorized to do
business as a banking institution in the State of Illinois or the State of New
York), in good standing, having an office or agency in the State of Illinois or
the State of New York, which is authorized under such laws to exercise corporate
trust or stock transfer powers and is subject to supervision or examination by
federal or state authority and which has at the time of its appointment as
Rights Agent a combined capital and surplus of at least $100,000,000 and which
shall otherwise meet any requirements imposed by the New York Stock Exchange on
transfer agents and registrars or (b) is an Affiliate of a corporation described
in clause (a) of this sentence.  After appointment, the successor Rights Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further reasonable assurance, conveyance, act or deed necessary for the purpose.
Not later than the effective date of any such appointment, the Company shall
file notice thereof in writing with the predecessor Rights Agent and each
transfer agent of the Common Stock and the Preferred Stock, and mail a notice
thereof in writing to the registered holders of the Rights Certificates.
Failure to give any notice provided for in this Section 21 or any defect therein
shall not affect the legality or validity of the resignation or removal of the
Rights Agent or the appointment of the successor Rights Agent, as the case may
be.

          Section 22.    Issuance of New Rights Certificates.  Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares or
other securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement.  In addition, in connection
with the issuance or sale of shares of Common Stock following the Distribution
Date and prior to the redemption or expiration of the Rights, the Company (a)
shall, with respect to shares of Common Stock so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, granted or
awarded prior to the Distribution Date, 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 Rights Certificates representing an appropriate number of Rights
in connection with such issuance or sale; provided, however, that (i) no such
Rights Certificate shall be issued if, and to the extent that, the Company shall
be advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Rights Certificate would be issued, and (ii) no such Rights Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

          Section 23.    Redemption and Termination.

          (a) The Board of Directors of the Company may, at its option, at any
time prior to the earlier of (i) the Close of Business on the tenth day
following the Stock Acquisition Date (or, if the Stock Acquisition Date shall
have occurred prior to the Record Date, the Close of Business on the tenth day
following the Record Date), or (ii) the Final Expiration Date, redeem all but
not less

                                      -31-
<PAGE>
 
than all of the then outstanding Rights at a redemption price of $.01 per Right,
as such amount may be appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof (such redemption
price being hereinafter referred to as the "Redemption Price"). Notwithstanding
anything contained in this Agreement to the contrary, the Rights shall not be
exercisable after the first occurrence of a Section 11(a)(ii) Event until such
time as the Company's right of redemption hereunder has expired.  The Company
may, at its option, pay the Redemption Price in cash, shares of Common Stock
(based on the "current market price", as defined in Section 11(d)(i) hereof, of
the Common Stock at the time of redemption) or any other form of consideration
deemed appropriate by the Board of Directors.  The redemption of the Rights by
the Board of Directors 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.

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

          (c) Notwithstanding the provisions of Section 23(a), in the event that
a majority of the Board of Directors of the Company is elected by stockholder
action by written consent, or is comprised of persons elected at a meeting of
stockholders who were not nominated by the Board of Directors of the Company in
office immediately prior to such meeting, then for a period of one hundred
eighty (180) days following the effectiveness of such election (the "180 Day
Period"), the Rights may not be redeemed.

          Section 24.    Exchange.

          (a) The Board of Directors of the Company may, at its option, at any
time after any Person becomes an Acquiring Person, exchange all or part of the
then outstanding and exercisable Rights (which shall not include Rights that
have become void pursuant to the provisions of Section 7(e) hereof) for shares
of Common Stock at an exchange ratio of one share of Common Stock per Right,
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or of any  Subsidiary of the Company,
or any Person organized, appointed or established by the Company for or pursuant
to the terms of any such plan),

                                      -32-
<PAGE>
 
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of fifty percent (50%) or more of the Common Stock then
outstanding.

          (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to subsection (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of shares of Common Stock equal
to the number of such Rights held by such holder multiplied by the Exchange
Ratio.  The Company shall promptly give public notice of any exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange.  The Company promptly shall mail a notice
of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent.  Any
notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will
state the method by which the exchange of the Common Stock for Rights will be
effected and, in the event of any partial exchange, the number of Rights which
will be exchanged.  Any partial exchange will be effected pro rata based on the
number of Rights (other than Rights which have become void pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights.

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

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

          (e) The Company shall not be required to issue fractions of shares of
Common Stock or to distribute certificates which evidence fractional shares of
Common Stock.  In lieu of such fractional shares of Common Stock, there shall be
paid to the registered holders of the Rights Certificates with regard to which
such fractional shares of Common Stock would otherwise be issuable, an amount in
cash equal to the same fraction of the current market value of a whole share of
Common Stock.  For the purposes of this subsection (e), the current market value
of a whole share of Common Stock shall be the closing price of a share of Common
Stock (as determined pursuant to the second sentence of Section 11(d)(i) hereof)
for the Trading Day immediately prior to the date of exchange pursuant to this
Section 24.

          Section 25.    Notice of Certain Events.

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

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

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

          True North Communications Inc.
          101 East Erie Street
          Chicago, Illinois  60611-2897
          Attention:  Treasurer

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

          First Chicago Trust Company of New York

          Attention:  Tenders and Exchange Administration

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

          Section 27.    Supplements and Amendments.  The Company may from time
to time supplement or amend this Agreement without the approval of any holders
of Rights Certificates in order to cure any ambiguity, to correct or supplement
any provision contained herein which may be defective or inconsistent with any
other provision herein, or to make any other provisions with respect to the
Rights which the Company may deem necessary or desirable, any such supplement or
amendment to be evidenced by a writing signed by the Company and the Rights
Agent; provided, however, that from and after such time as any Person becomes an
Acquiring Person, this Agreement shall not be amended in any manner which would
adversely affect the interests of the holders of Rights. Prior to the
Distribution Date, the interest of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Stock. Without limiting
the foregoing, the Company may at any time prior to such time as any Person
becomes an Acquiring Person amend this Agreement to lower the thresholds set
forth in Sections 1(a) and 3(a) to a percentage that (subject to exceptions for
specified persons or groups which may from time to time be excepted from the
definition of "Acquiring Person") is not less than the greater of (i) the sum of
 .001% and the largest percentage of the outstanding shares of Common Stock then
known by the Company to be beneficially owned

                                      -35-
<PAGE>
 
by any Person (other than the Company, any Subsidiary of the Company, any
employee benefit plan of the Company or of any Subsidiary of the Company, any
Person organized, appointed or established by the Company for or pursuant to the
terms of any such plan or, to the extent excepted from the definition of
"Acquiring Person", other specified persons or groups) and (ii) 10.0%.
Notwithstanding anything contained in this Agreement to the contrary, during the
pendency of any 180 Day Period, no supplement or amendment shall be made to this
Agreement, other than an amendment or supplement to cure any ambiguity or to
correct or supplement any provision contained herein which may be defective or
inconsistent with any other provision hereof.

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

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

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

                                      -36-
<PAGE>
 
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 of the Company.

          Section 32.  Governing Law.  This Agreement, each Right and each
Rights Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts made
and to be performed entirely within such State.

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

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

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.

                General Corporation Law of the State of Delaware

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


          The undersigned do hereby certify that the following resolution was
duly adopted by the Board of Directors of True North Communications Inc., a
Delaware corporation (the "Corporation"), at a meeting duly convened and held on
November 4, 1998, at which a quorum was present and acting throughout:

          RESOLVED, that pursuant to the authority vested in the board of
directors of the Corporation by the Restated Certificate of Incorporation, as
amended (the "Charter"), the board of directors does hereby create, authorize
and provide for the issue of a series of Preferred Stock, par value $1.00 per
share, of the Corporation, to be designated "Series B Junior Participating
Preferred Stock" (hereinafter referred to as the "Series B Preferred Stock"),
initially consisting of 45,000 shares, and to the extent that the designations,
powers, preferences and relative and other special rights and the
qualifications, limitations or restrictions of the Series B Preferred Stock are
not stated and expressed in the Charter, does hereby fix and herein state and
express such designations, powers, preferences and relative and other special
rights and the qualifications, limitations and restrictions thereof, as follows
(all terms used herein which are defined in the Charter shall be deemed to have
the meanings provided therein):

          Section 1.  Designation and Amount.  The shares of such series shall
be designated as "Series B Junior Participating Preferred Stock" and the number
of shares constituting such series shall be 45,000.

          Section 2.  Dividends and Distributions.

          (A)  Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series B Preferred Stock with respect to dividends, the holders of shares of
Series B Preferred Stock shall be entitled to receive, when, as
<PAGE>
 
and if declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the first business day of
January, April, July and October in each year (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series B Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (a) $.01 or (b) subject to the provision
for adjustment hereinafter set forth, 2,000 times the aggregate per share amount
of all cash dividends, plus 2,000 times the aggregate per share amount (payable
in kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock,
par value $33-1/3 per share, of the Corporation (the "Common Stock") since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series B Preferred Stock.  In the event the Corporation
shall at any time after November 4, 1998 (the "Rights Declaration Date") (i)
declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each case the amount to which
holders of shares of Series B Preferred Stock were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

          (B)  The Corporation shall declare a dividend or distribution on the
Series B Preferred Stock as provided in paragraph (A) above immediately after it
declares a dividend or distribution on the Common Stock (other than a dividend
payable in shares of Common Stock); provided, however, that, in the event no
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, subject to the prior and superior rights of the
holders of any shares of any series of Preferred Stock ranking prior to and
superior to the shares of Series B Preferred Stock with respect to dividends, a
dividend of $.01 per share on the Series B Preferred Stock shall nevertheless by
payable on such subsequent Quarterly Dividend Payment Date.

          (C)  Dividends shall begin to accrue and be cumulative on outstanding
shares of Series B Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series B 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 B Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date,
in either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date.  Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series B 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-

                                      A-2
<PAGE>
 
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 B Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than 60 days
prior to the date fixed for the payment thereof.

          Section 3.  Voting Rights.

          The holders of shares of Series B Preferred Stock shall have the
following voting rights:

          (A)  Subject to the provision for adjustment hereinafter set forth,
each share of Series B Preferred Stock shall entitle the holder thereof to 2,000
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the number of
votes per share to which holders of shares of Series B Preferred Stock were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

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

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

          (ii)  During any default period, such voting right of the holders of
Series B Preferred Stock may be exercised initially at a special meeting called
pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of
stockholders, and thereafter at annual meetings of stockholders, provided that
such voting right shall not be exercised unless the holders of ten percent (10%)
in number of shares of Preferred Stock outstanding shall be present in person or
by proxy.  The absence of a quorum of the holders of Common Stock shall not
affect the exercise by the holders of Preferred Stock of such voting rights.  At
any meeting at which the holders of Preferred Stock shall exercise such voting
right initially during an existing default period, they shall have the right,
voting

                                      A-3
<PAGE>
 
as a class, to elect Directors to fill such vacancies, if any, in the Board of
Directors as may then exist up to two (2) Directors or, if such right is
exercised at an annual meeting, to elect two (2) Directors. If the number which
may be so elected at any special meeting does not amount to the required number,
the holders of the Preferred Stock shall have the right to make such increase in
the number of Directors as shall be necessary to permit the election by them of
the required number.  After the holders of the Preferred Stock shall have
exercised their right to elect Directors in any default period and during the
continuance of such period, the number of Directors shall not be increased or
decreased except by vote of the holders of Preferred Stock as herein provided or
pursuant to the rights of any equity securities ranking senior to or pari passu
with the Series B Preferred Stock.

          (iii)  Unless the holders of Preferred Stock shall, during an existing
default period, have previously exercised their right to elect Directors, the
Board of Directors may order, or any stockholder or stockholders owning in the
aggregate not less than ten percent (10%) of the total number of shares of
Preferred Stock outstanding, irrespective of series, may request, the calling of
special meeting of the holders of Preferred Stock, which meeting shall thereupon
be called by the Chief Executive Officer, the President, any Senior Vice
President, any Executive Vice President, the Chief Financial Officer, the
Treasurer or the Secretary of the Corporation.  Notice of such meeting and of
any annual meeting at which holders of Preferred Stock are entitled to vote
pursuant to this paragraph (C)(iii) shall be given to each holder of record of
Preferred Stock by mailing a copy of such notice to him or her at his or her
last address as the same appears on the books of the Corporation. Such meeting
shall be called for a time not earlier than 10 days and not later than 50 days
after such order or request, or in default of the calling of such meeting within
50 days after such order or request, such meeting may be called on similar
notice by any stockholder or stockholders owning in the aggregate not less than
ten percent (10%) of the total number of shares of Preferred Stock outstanding.
Notwithstanding the provisions of this paragraph (C)(iii), no such special
meeting shall be called during the period within 50 days immediately preceding
the date fixed for the next annual meeting of the stockholders.

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

          (v)  Immediately upon the expiration of a default period, (x) the
right of the holders of Preferred Stock as a class to elect Directors shall
cease, (y) the term of any Directors elected by the holders of Preferred Stock
as a class shall terminate, and (z) the number of Directors shall be such

                                      A-4
<PAGE>
 
number as may be provided for in the certificate of incorporation or by-laws
irrespective of any increase made pursuant to the provisions of paragraph
(C)(ii) of this Section 3 (such number being subject, however, to change
thereafter in any manner provided by law or in the certificate of incorporation
or by-laws).  Any vacancies in the Board of Directors effected by the provisions
of clauses (y) and (z) in the preceding sentence may be filled by a majority of
the remaining Directors.

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

          Section 4.  Certain Restrictions.

          (A)  Whenever quarterly dividends or other dividends or distributions
payable on the Series B Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series B 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
     capital stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series B Preferred Stock;

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

          (iv)  purchase or otherwise acquire for consideration any shares of
     Series B Preferred Stock, or any shares of capital stock ranking on a
     parity with the Series B Preferred Stock, except in accordance with a
     purchase offer made in writing or by publication (as determined by the
     Board of Directors) to all holders of such shares upon such terms as the
     Board of Directors, after consideration of the respective annual dividend
     rates and other relative rights and preferences of the respective series

                                      A-5
<PAGE>
 
     and classes, shall determine in good faith will result in fair and
     equitable treatment among the respective series or classes.

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

          Section 5.  Reacquired Shares.

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

          Section 6.  Liquidation, Dissolution or Winding Up.

          (A)  Upon any liquidation (voluntary or otherwise), dissolution or
winding up of the Corporation, no distribution shall be made to the holders of
shares of capital stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series B Preferred Stock unless,
prior thereto, the holders of shares of Series B Preferred Stock shall have
received $100 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment
(the "Series B Liquidation Preference").  Following the payment of the full
amount of the Series B Liquidation Preference, no additional distributions shall
be made to the holders of shares of Series B Preferred Stock unless, prior
thereto, the holders of shares of Common Stock shall have received an amount per
share (the "Common Adjustment") equal to the quotient obtained by dividing (i)
the Series B Liquidation Preference by (ii) 2,000 (as appropriately adjusted as
set forth in subparagraph (C) below to reflect such events as stock splits,
stock dividends and recapitalizations with respect to the Common Stock) (such
number in clause (ii), the "Adjustment Number").  Following the payment of the
full amount of the Series B Liquidation Preference and the Common Adjustment in
respect of all outstanding shares of Series B Preferred Stock and Common Stock,
respectively, and the payment of liquidation preferences of all other shares of
capital stock which rank prior to or on a parity with Series B Preferred Stock,
holders of Series B Preferred Stock and holders of shares of Common Stock shall
receive their ratable and proportionate share of the remaining assets to be
distributed in the ratio of the Adjustment Number to 1 with respect to such
Preferred Stock and Common Stock, on a per share basis, respectively.

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

                                      A-6
<PAGE>
 
respective liquidation preferences.  In the event, however, that there are not
sufficient assets available to permit payment in full of the Common Adjustment,
then such remaining assets shall be distributed ratably to the holders of Common
Stock.

          (C)  In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

          Section 7.  Consolidation, Merger, etc.

          In case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common Stock are
exchanged for or changed into other capital stock or securities, cash and/or any
other property, then in any such case the shares of Series B Preferred Stock
shall at the same time be similarly exchanged or changed into an amount per
share (subject to the provision for adjustment hereinafter set forth) equal to
2,000 times the aggregate per share amount of capital stock, securities, cash
and/or any other property (payable in kind), as the case may be, for which or
into which each share of Common Stock is exchanged or changed.  In the event the
Corporation shall at any time after the Rights Declaration Date (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Series B
Preferred Stock shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

          Section 8.  No Redemption.

          The shares of Series B Preferred Stock shall not be redeemable.

          Section 9.  Ranking.

          The Series B Preferred Stock shall rank junior to all other series of
the Corporation's Preferred Stock as to the payment of dividends and the
distribution of assets, whether or not upon the dissolution, liquidation or
winding up of the Corporation, unless the terms of any such series shall provide
otherwise.

                                      A-7
<PAGE>
 
          Section 10.  Amendment.

          The Charter of the Corporation shall not be amended in any manner
which would materially alter or change the powers, preferences or special rights
of the Series B Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series B Preferred Stock, voting separately as a class.

          Section 11.  Fractional Shares.

          Series B 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 B Preferred Stock.

                               Rights Certificate

                         TRUE NORTH COMMUNICATIONS INC.


          This certifies that _______________, or registered assigns, is the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the Rights
Agreement, dated as of November 4, 1998 (the "Rights Agreement"), between True
North Communications Inc., a Delaware corporation (the "Company"), and First
Chicago Trust Company of New York, a New York corporation (the "Rights Agent"),
to purchase from the Company at any time prior to 5:00 P.M. (Chicago, Illinois
time) on November 30, 2008 at the office or offices of the Rights Agent
designated for such purpose, or its successors as Rights Agent, one two-
thousandth of a fully paid, nonassessable share of Series B Junior Participating
Preferred Stock, par value $1.00 per share (the "Preferred Stock") of the
Company, at a purchase price of $100 per one two-thousandth of a share (the
"Purchase Price"), upon presentation and surrender of this Rights Certificate
with the Form of Election to Purchase and related Certificate duly executed.
The number of Rights evidenced by this Rights Certificate (and the number of
shares which may be purchased upon exercise thereof) set forth above, and the
Purchase Price per share set forth above, are the number and Purchase Price as
of November 30, 1998, based on the Preferred Stock as constituted at such date.
The Company reserves the right to require prior to the occurrence of a
Triggering Event (as such term is defined in the Rights Agreement) that, upon
any exercise of Rights, a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

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

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

          This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances

                                      B-2
<PAGE>
 
set forth in the Rights Agreement.  Copies of the Rights Agreement are on file
at the above-mentioned office of the Rights Agent and are also available upon
written request to the Secretary of the Company.

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

          Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may, in each case at the option of the Company, be
(i) redeemed by the Company at its option at a redemption price of $.01 per
Right or (ii) exchanged in whole or in part for shares of Common Stock or other
securities of the Company.  Immediately upon the action of the Board of
Directors of the Company authorizing redemption, the Rights will terminate and
the only right of the holders of Rights will be to receive the redemption price.
Under certain circumstances set forth in the Rights Agreement, the Rights may
not be redeemed for a period of one hundred eighty (180) days.

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

          No holder of this Rights Certificate shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of shares of Preferred
Stock or of any other securities of the Company which may at any time be
issuable on the exercise hereof, nor shall anything contained in the Rights

                 SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK
                 ---------------------------------------------


          On November 4, 1998, the Board of Directors of True North
Communications Inc. (the "Company") declared a dividend distribution of one
Right for each outstanding share of the Company's common stock, $.33-1/3 par 
value per share ("Common Stock"), to stockholders of record at the close of
business on November 30, 1998. Each Right entitles the registered holder to
purchase from the Company a unit consisting of one two-thousandth of a share (a
"Unit") of Series B Junior Participating Preferred Stock, par value $1.00 per
share (the "Preferred Stock"), of the Company at a price of $100 per Unit (the
"Purchase Price"), subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") dated as of
November 4, 1998 between the Company and First Chicago Trust Company of New
York, as Rights Agent.

          Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
certificates will be distributed.  The Rights will separate from the Common
Stock and the Distribution Date will occur upon the earliest of (i) 10 days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 15% or more (or, in the case of Publicis
Communication, 22% or more) of the outstanding shares of Common Stock (the
"Stock Acquisition Date"), (ii) 10 business days (or such later date as may be
determined by action of the Board of Directors prior to such time as any person
or group becomes an Acquiring Person) following the commencement of a tender
offer or exchange offer which, if consummated, would result in a person or group
beneficially owning 15% or more (or, in the case of Publicis Communication, 22%
or more) of the outstanding shares of Common Stock or (iii) during any 180 Day
Period (as defined below), the date immediately following the date of execution
of an agreement relating to or providing for (x) an acquisition of the Company
in a merger or other business combination transaction in which the Company would
not be the surviving corporation, (y) an acquisition of the Company in a merger
or other business combination transaction in which the Company would be the
surviving corporation and in which all or part of the Common Stock would be
converted into securities of another entity, cash or other property, or (z) 50%
or more of the Company's assets or earning power being sold or transferred.

          Until the Distribution Date, (i) the Rights will be evidenced by the
Common Stock certificates and will be transferred with and only with such Common
Stock certificates, (ii) new Common Stock certificates issued on or after
November 30, 1998 will contain a notation incorporating the Rights Agreement by
reference and (iii) the surrender for transfer of any certificates for Common
Stock outstanding will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificate.

          Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the occurrence of a Triggering Event (as defined below) that,
upon any exercise of Rights, a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.
<PAGE>
 
          The Rights are not exercisable until the Distribution Date and will
expire at the close of business on November 30, 2008, unless earlier redeemed by
the Company as described below.

          As soon as practicable after the Distribution Date, Rights
certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and, thereafter, the separate Rights
certificates alone will represent the Rights.  Except as otherwise provided in
the Rights Agreement, only shares of Common Stock issued prior to the
Distribution Date will be issued with Rights.

          In the event that, at any time following the Distribution Date, a
person or group becomes an Acquiring Person, each holder of a Right will
thereafter have the right to receive, upon exercise, Common Stock having a value
equal to two times the exercise price of the Right.  If an insufficient number
of shares of Common Stock is authorized for issuance, then the Board would be
required to substitute cash, property or other securities of the Company for the
Common Stock. Notwithstanding any of the foregoing, following the occurrence of
the event set forth in this paragraph, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person will be null and void.  However, Rights are not exercisable
following the occurrence of the event set forth in this paragraph until such
time as the Rights are no longer redeemable by the Company as set forth below.

          For example, at an exercise price of $100 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following an event
set forth in the preceding paragraph would entitle its holder to purchase $200
worth of Common Stock (or other consideration, as noted above) for $100.
Assuming that the Common Stock had a per share value of $25 at such time, the
holder of each valid Right would be entitled to purchase eight shares of Common
Stock for $100.

          In the event that, at any time following the Stock Acquisition Date or
during the pendency of a 180 Day Period, (i) the Company is acquired in a merger
or other business combination transaction in which the Company is not the
surviving corporation, (ii) the Company is acquired in a merger or other
business combination transaction in which the Company is the surviving
corporation and all or part of the Common Stock is converted into securities of
another entity, cash or other property, or (iii) 50% or more of the Company's
assets or earning power is sold or transferred, each holder of a Right (except
Rights which previously have been voided as set forth above) shall thereafter
have the right to receive, upon exercise, common stock of the acquiring company
having a value equal to two times the exercise price of the Right.  The events
set forth in this paragraph and in the second preceding paragraph are referred
to as the "Triggering Events."

          The purchase price payable, and the number of Units of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) if holders of the Preferred Stock are granted certain
rights, options or warrants to subscribe for Preferred Stock or convertible
securities at less than the current

                                      C-2
<PAGE>
 
market price of the Preferred Stock, or (iii) upon the distribution to holders
of the Preferred Stock of evidences of indebtedness or assets (excluding regular
quarterly cash dividends) or of subscription rights or warrants (other than
those referred to above).

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

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

          In general, the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (subject to adjustment and payable in cash,
Common Stock or other consideration deemed appropriate by the Board of
Directors) at any time until ten days following the Stock Acquisition Date.
Immediately upon the action of the Board of Directors authorizing any
redemption, the Rights will terminate and the only right of the holders of
Rights will be to receive the redemption price.  Notwithstanding the foregoing,
in the event that a majority of the Board of Directors of the Company is elected
by stockholder action by written consent, or is comprised of persons elected at
a meeting of stockholders who were not nominated by the Board of Directors in
office immediately prior to such meeting, then for a period of one hundred
eighty (180) days following the effectiveness of such election (the "180 Day
Period"), the Rights may not be redeemed.

          Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
result in the recognition of taxable income by stockholders or the Company,
stockholders may, depending upon the circumstances, recognize taxable income
after a Triggering Event.

          The terms of the Rights may be amended by the Board of Directors of
the Company without the consent of the holders of the Rights, including an
amendment to lower certain thresholds described above to not less than the
greater of (i) the sum of .001% and the largest percentage of the outstanding
shares of Common Stock then known to the Company to be beneficially owned by any
person or group of affiliated or associated persons and (ii) 10%, except that
from and after such time as any person or group of affiliated or associated
persons becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights.  Notwithstanding the foregoing, during
the pendency of any 180 Day Period, the terms of the Rights may not be amended
other than to cure ambiguities or to correct defects or inconsistencies.
