                                   AS AMENDED

                                      ----

     The name of the Corporation is StanCorp Financial Group, Inc.

                                   ARTICLE 2.
                                 Capital Stock
                                 -------------

     A.   The Corporation is authorized to issue a total of Four Hundred Million
(400,000,000) shares, consisting of Three Hundred Million (300,000,000) shares
of Common Stock and One Hundred Million (100,000,000) shares of Preferred Stock.

     B.   Holders of Common Stock are entitled to one vote per share.  On
dissolution of the Corporation, after any preferential amount with respect to
the Preferred Stock has been paid or set aside, the holders of Common Stock and
the holders of any series of Preferred Stock entitled to participate in the
distribution of assets are entitled to receive the net assets of the
Corporation.

     C.   The Board of Directors is authorized, subject to limitations
prescribed by the Oregon Business Corporation Act, as amended from time to time
(the "Act"), and by the provisions of this Article, to provide for the issuance
of shares of Preferred Stock in series, to establish from time to time the
number of shares to be included in each series and to determine the
designations, relative rights, preferences and limitations of the shares of each
series.  The authority of the Board of Directors with respect to each series
includes determination of the following:

          (1) The number of shares in and the distinguishing designation of that
series;

          (2) Whether shares of that series shall have full, special,
conditional, limited or no voting rights, except to the extent otherwise
provided by the Act;

          (3) Whether shares of that series shall be convertible and the terms
and conditions of the conversion, including provision for adjustment of the
conversion rate in circumstances determined by the Board of Directors;

          (4) Whether shares of that series shall be redeemable and the terms
and conditions of redemption, including the date or dates upon or after which
they shall be 
<PAGE>
 
redeemable and the amount per share payable in case of redemption, which amount
may vary under different conditions or at different redemption dates;

          (5) The dividend rate, if any, on shares of that series, the manner of
calculating any dividends and the preferences of any dividends;

          (6) The rights of shares of that series in the event of voluntary or
involuntary dissolution of the Corporation and the rights of priority of that
series relative to the Common Stock and any other series of Preferred Stock on
the distribution of assets on dissolution; and

          (7) Any other rights, preferences and limitations of that series that
are permitted by law to vary.

     D.   Series A Preferred Stock.
          ------------------------ 

          (1) Designation and Amount.  The shares of such series shall be
              ----------------------                                     
designated as "Series A Preferred Shares" and the number of shares constituting
such series shall be 500,000.

          (2)  Dividends and Distributions.
               --------------------------- 

               (i) The holders of shares of Series A Preferred Shares shall be
     entitled to receive, when and as declared by the Board of Directors, out of
     funds legally available for the purpose, dividends in an amount per share
     equal to 100 (the "Adjustment Number") multiplied by the aggregate per
     share amount of all cash dividends, and the Adjustment Number multiplied by
     the aggregate per share amount (payable in kind) of all non-cash dividends
     or other distributions other than a dividend payable in Common Stock or a
     subdivision of the outstanding Common Stock (by reclassification or
     otherwise), declared on the Common Stock of the Corporation (the "Common
     Stock") after the first issuance of any share or fraction of a share of
     Series A Preferred Shares.

               (ii) The Corporation shall declare a dividend or distribution on
     the Series A Preferred Shares as provided in subparagraph 2(i) at the same
     time that it declares a dividend or distribution on the Common Stock (other
     than a dividend payable in Common Stock).

               (iii)     Dividends shall not be cumulative.  Unpaid dividends
     shall not bear interest.  Dividends paid on the Series A Preferred Shares
     in an amount less than the total amount of such dividends at the time
     accrued and payable on such shares shall be allocated pro rata on a share-
     by-share basis among all such shares at the time outstanding.

                                       2
<PAGE>
 
          (3) Voting Rights.  The holders of Series A Preferred Shares shall
              -------------                                                 
have the following voting rights:

               (i) Each Series A Preferred Share shall entitle the holder
     thereof to the number of votes equal to the Adjustment Number then in
     effect on all matters submitted to a vote of the shareholders of the
     Corporation.

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

     (4)  Certain Restrictions.
          -------------------- 

               (i) Whenever dividends or distributions payable on the Series A
     Preferred Shares as provided in subparagraph 2 have not been declared or
     paid for any fiscal year, until all such dividends and distributions for
     such fiscal year on Series A Preferred Shares outstanding shall have been
     declared and paid in full, the Corporation shall not in such fiscal year:

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

                    (b) purchase or otherwise acquire for consideration any
          Series A Preferred Shares or any shares of stock ranking on a parity
          with the Series A Preferred Shares, 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 dividend
          rates and other relative rights and preferences of the respective
          series and classes, shall determine in good faith will result in fair
          and equitable treatment among the respective series or classes.

               (ii) 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
     subparagraph 4(i), purchase or otherwise acquire such shares at such time
     and in such manner.

                                       3
<PAGE>
 
          (5) Restriction on Issuance of Shares; Reacquired Shares.  The
              ----------------------------------------------------      
Corporation shall not issue any Series A Preferred Shares except upon exercise
of rights (the "Rights") issued pursuant to the Rights Agreement dated as of
April 21, 1999, between the Corporation and ChaseMellon Shareholder Services,
LLC,  (the "Rights Agreement"), a copy of which is on file with the secretary of
the Corporation at its principal executive office and shall be made available to
shareholders of record without charge upon written request.  Any Series A
Preferred Shares purchased or otherwise acquired by the Corporation in any
manner whatsoever may be restored to the status of authorized but unissued
shares after the acquisition thereof.  All such shares shall upon any such
restoration become authorized but unissued shares of Preferred Shares and may be
reissued as part of a new series of Preferred Shares to be created by the Board
of Directors, subject to the conditions and restrictions on issuance set forth
herein.

          (6) Liquidation, Dissolution or Winding Up.
              -------------------------------------- 

               (i) Upon any liquidation (voluntary or otherwise), dissolution or
     winding up of the Corporation, no distribution shall be made to the holders
     of shares of stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Series A Preferred Shares
     unless, prior thereto, the holders of shares of Series A Preferred Shares
     shall have received the Adjustment Number multiplied by the per share
     amount to be distributed to holders of Common Stock, plus an amount equal
     to declared and unpaid dividends and distributions thereon to the date of
     such payment (the "Series A Liquidation Preference").  Following the
     payment of the full amount of the Series A Liquidation Preference, no
     additional distributions shall be made to the holders of shares of Series A
     Preferred Shares.

               (ii) In the event that there are not sufficient assets available
     to permit payment in full of the Series A Liquidation Preference and the
     liquidation preferences of all other series of Preferred Shares, if any,
     which rank senior to or on a parity with the Series A Preferred Shares,
     then assets shall be distributed first to holders of any series of
     Preferred Shares ranking senior to the Series A Preferred Shares to the
     extent of their liquidation preferences and such remaining assets shall be
     distributed ratably to the holders of Series A Preferred Shares and such
     parity shares in proportion to their respective liquidation preferences.

          (7) Consolidation, Merger, etc.  In case the Corporation shall enter
              ---------------------------                                     
into any consolidation, merger, combination or other transaction in which the
Common Stock is exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case the Series A Preferred Shares
shall at the same time be similarly exchanged or changed in an amount per share
equal to the Adjustment Number multiplied by the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each common Share is changed or exchanged.

                                       4
<PAGE>
 
          (8) Anti-Dilution Adjustments to Adjustment Number.  In the event the
              ----------------------------------------------                   
Corporation shall at any time after April 21, 1999 (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 for all purposes of this Article 2 shall be adjusted by
multiplying the Adjustment Number then in effect 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.  In the event the Corporation
shall at any time after the Rights Declaration Date, fix a record date for the
issuance of rights, options or warrants to all holders of Common Stock entitling
them (for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Common Stock or securities convertible into Common
Stock at a price per Common Stock (or having a conversion price per share, if a
security convertible into Common Stock) less than the then Current Per Share
Market Price of the Common Stock (as defined in Section 11(d) of the Rights
Agreement) on such record date, then in each such case the Adjustment Number for
all purposes of this Article 2 shall be adjusted by multiplying the Adjustment
Number then in effect by, a fraction, the numerator of which shall be the number
of shares of Common Stock outstanding on such record date plus the number of
additional shares of Common Stock to be offered for subscription or purchase (or
into which the convertible securities so to be offered are initially
convertible) and the denominator of which shall be the number of shares of
Common Stock outstanding on such record date plus the number of shares of Common
Stock which the aggregate offering price of the total number of shares of Common
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 Per
Share Market Price (as defined in Section 11(d) of the Rights Agreement).  In
case such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors. Common Stock owned by or
held for the account of the Corporation shall not be deemed outstanding for the
purpose of any such computation.  Such adjustment shall be made successively
whenever such a record date is fixed.  In the event that such rights, options or
warrants are not so issued, the Adjustment Number shall be readjusted as if such
record date had not been fixed; and to the extent such rights, options or
warrants are issued but not exercised prior to their expiration, the Adjustment
Number shall be readjusted to be the number which would have resulted from the
adjustment provided for in this paragraph 8 if only the rights, options or
warrants that were exercised had been issued.

          (9) No Redemption.  The Series A Preferred Shares shall not be
              -------------                                             
redeemable at the option of the Corporation or any holder thereof.
Notwithstanding the foregoing sentence, the Corporation may acquire Series A
Preferred Shares in any other manner permitted by law.

          (10) Amendment.  Subsequent to the Distribution Date (as defined in
               ---------                                                     
the Rights Agreement) these Articles of Incorporation shall not be further
amended in any 

                                       5
<PAGE>
 
manner which would materially alter or change the preferences,
limitations and relative rights of the Series A Preferred Shares so as to affect
them adversely without the affirmative vote of the holders of a majority of the
outstanding Series A Preferred shares, voting separately as a class.

          (11) Fractional Shares.  Series A Preferred Shares may be issued in
               -----------------                                             
fractions of a share in integral multiples of one one-hundredth of a share,
which shall entitle the holder, in proportion to such holders fractional shares,
to exercise voting rights, receive dividends, participate in distributions and
to have the benefit of all other rights of holders of Series A Preferred Shares.

                                   ARTICLE 3
                         Number and Tenure of Directors
                         ------------------------------

     A.   The initial number of directors of the Corporation shall be not less
than three (3).  At such time as the Corporation has more than one shareholder
the number of directors of the Corporation shall be not less than nine (9) nor
more than twenty-one (21), and within such limits the exact number shall be
fixed and increased or decreased from time to time by resolution of the Board of
Directors.  At such time as the number of directors is first increased to nine
or more, the directors shall be divided into three classes, as nearly equal in
number as possible, with the term of office of the first class ("Class I") to
expire at the first annual meeting of shareholders, the term of office of the
second class ("Class II") to expire at the second annual meeting of shareholders
following the classification and the term of office of the third class ("Class
III") to expire at the third annual meeting of shareholders following the
classification.  At each annual meeting of shareholders following such initial
classification and election, directors elected to succeed those directors whose
terms expire shall be elected to serve three-year terms and until their
successors are elected and qualified, so that the term of one class of directors
will expire each year.  When the number of directors is changed within the
limits provided herein, any newly created directorships, or any decrease in
directorships, shall be so apportioned among the classes as to make all classes
as nearly equal as possible, provided that no decrease in the number of
directors constituting the Board of Directors shall shorten the term of any
incumbent director.

     B.   Directors of the Company may be removed only for cause at a meeting of
shareholders called expressly for that purpose.

     C.   Any vacancy on the Board of Directors, including a vacancy resulting
from an increase in the number of directors, may be filled by the Board of
Directors, the remaining directors if less than a quorum (by the vote of a
majority thereof) or by a sole remaining director.  If the vacancy is not so
filled, it shall be filled by the shareholders at the next annual meeting of
shareholders.  A vacancy that will occur at a specified later date, by reason of
a resignation or otherwise, may be filled before the vacancy occurs, but the new
director may not take office until the vacancy occurs.

                                       6
<PAGE>
 
     D.   This Article 3 may not be amended, altered, changed or repealed unless
the amendment is approved by the vote of holders of 70 percent of the shares
then entitled to vote at an election of directors.

                                   ARTICLE 4
                              Amendment of  Bylaws
                              --------------------

     Both the Board of Directors and the shareholders shall have the power to
alter, amend or repeal the Bylaws of the Corporation.  Any repeal or change of
the Bylaws by the shareholders shall require the affirmative vote of not less
than 70 percent of the votes entitled to be cast on the matter.  This Article 4
may not be amended, altered, changed or repealed unless the amendment is
approved by the vote of holders of 70 percent of the shares then entitled to
vote at an election of directors.

                                   ARTICLE 5
                             No Personal Liability
                             ---------------------

     No director of the Corporation shall be personally liable to the
Corporation or its shareholders for monetary damages for conduct as a director;
provided that this Article shall not eliminate the liability of a director for
any act or omission for which such elimination of liability is not permitted
under the Oregon Business Corporation Act.  No amendment to the Oregon Business
Corporation Act that further limits the acts or omissions for which elimination
of liability is permitted shall affect the liability of a director for any act
or omission which occurs prior to the effective date of such amendment.

                                   ARTICLE 6

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

     A.   Whether or not a vote of stockholders is otherwise required, the vote
of the holders of not less than 70 percent of the outstanding shares of "Voting
Stock" (as hereinafter defined) of the Corporation shall be required for the
approval or authorization of any "Business Combination" (as hereinafter defined)
with any "Substantial Shareholder" (as hereinafter defined) or any Business
Combination in which a Substantial Shareholder has an interest (except
proportionately as a stockholder of the Corporation); provided, however, that
the 70 percent voting requirement shall not be applicable if either:

          (1) The "Continuing Directors" (as hereinafter defined) of the
Corporation by at least a two-thirds vote (a) have expressly approved in advance
the acquisition of the outstanding shares of Voting Stock that caused such
Substantial Shareholder to become a Substantial Shareholder, or (b) have
expressly approved such Business Combination; or

          (2) The cash or fair market value (as determined by at least a
majority of the Continuing Directors) of the property, securities or other
consideration to be received per share by holders of Voting Stock of the
Corporation (other than the Substantial Shareholder) in the Business Combination
is not less than the "Highest Per Share Price" or the "Highest Equivalent Price"
(as those terms are hereinafter defined) paid by the Substantial Shareholder
involved in the Business Combination in acquiring any of its holdings of the
Corporation's Voting Stock acquired in the last two years.

     B.   For purposes of this Article 7:

          (1) The term "Business Combination" shall include, without limitation,

controlled by or under common control with the Corporation, with or into any
Substantial Shareholder, or any entity controlled by or under common control
with such Substantial Shareholder, (b) any merger, exchange or consolidation of
a Substantial Shareholder, or any entity controlled by or under common control
with such Substantial Shareholder, with or into the Corporation or any entity
controlled by or under common control with the Corporation, (c) any sale, lease,
exchange, transfer or other disposition (in one transaction or a series of
transactions), including without limitation a mortgage or any other security
device, of all or any "Substantial Part" (as hereinafter defined) of the
property and assets of the Corporation, or any entity controlled by or under
common control with the Corporation, to a Substantial Shareholder, or any entity
controlled by or under common control with such Substantial Shareholder, (d) any
purchase, lease, exchange, transfer or other acquisition (in one transaction or
a series of transactions), including without limitation a mortgage or any other
security device, of all or any Substantial Part of the property and assets of a
Substantial Shareholder or any entity controlled by or under common control with
such Substantial Shareholder, by the Corporation, or any entity controlled by or
under common control with the Corporation, (e) any recapitalization of the
Corporation that would have the effect of 

                                       8
<PAGE>
 
increasing the voting power of a Substantial Shareholder, (f) the issuance,
sale, exchange or other disposition of any securities of the Corporation, or of
any entity controlled by or under common control with the Corporation, by the
Corporation or by any entity controlled by or under common control with the
Corporation, (g) any liquidation, spinoff, splitoff, splitup or dissolution of
the Corporation, and (h) any agreement, contract or other arrangement providing
for any of the transactions described in this definition of Business
Combination.

          (2) The term "Substantial Shareholder" shall mean and include (a) any
"Person" (as that term is defined in Section 2(2) of the Securities Act of 1933,
as in effect on the date these Articles of Incorporation become effective (the
"Effective Date")) which, together with its "Affiliates" (as hereinafter
defined) and "Associates" (as hereinafter defined), "Beneficially Owns" (as
defined in Rule 13d-3 of the General Rules and Regulations under the Securities
Exchange Act of 1934 as in effect on the Effective Date) in the aggregate 15
percent or more of the outstanding Voting Stock of the Corporation, and (b) any
Affiliate or Associate (other than the Corporation or a wholly owned subsidiary
of the Corporation) of any such Person.  Two or more Persons acting in concert
for the purpose of acquiring, holding or disposing of Voting Stock of the
Corporation shall be deemed a "Person."

          (3) Without limitation, any share of Voting Stock of the Corporation
that any Substantial Shareholder has the right to acquire at any time
(notwithstanding that Rule 13d-3 deems such shares to be beneficially owned if
such right may be exercised within 60 days) pursuant to any agreement, contract,
arrangement or understanding, or upon exercise of conversion rights, warrants or
options, or otherwise, shall be deemed to be Beneficially Owned by such
Substantial Shareholder and to be outstanding for purposes of subparagraph B(2)
above.

          (4) For the purposes of subparagraph A(2) of this Article, the term
"other consideration to be received" shall include, without limitation, Common
Stock or other capital stock of the Corporation retained by its existing
shareholders, other than any Substantial Shareholder or other Person who is a
party to such Business Combination, in the event of a Business Combination in
which the Corporation is the survivor.

          (5) The term "Voting Stock" shall mean all of the outstanding shares
of capital stock of the Corporation entitled to vote generally in the election
of directors, considered as one class, and each reference to a proportion of
shares of Voting Stock shall refer to such proportion of the votes entitled to
be cast by such shares.

          (6) The term "Continuing Director" shall mean a director of the
Corporation who was a member of the board of directors of the Corporation
immediately prior to the time that the Substantial Shareholder involved in a
Business Combination became a Substantial Shareholder.

                                       9
<PAGE>
 
          (7) A Substantial Shareholder shall be deemed to have acquired a share
of the Voting Stock of the Corporation at the time when such Substantial
Shareholder became the Beneficial Owner thereof.  With respect to the shares
owned by Affiliates, Associates or other Persons whose ownership is attributed
to a Substantial Shareholder under the foregoing definition of Substantial
Shareholder, if the price paid by such Substantial Shareholder for such shares
is not determinable by a majority of the Continuing Directors, the price so paid
shall be deemed to be the higher of (a) the price paid upon the acquisition
thereof by the Affiliate, Associate or other Person or (b) the market price of
the shares in question at the time when such Substantial Shareholder became the
Beneficial Owner thereof.

          (8) The terms "Highest Per Share Price" and "Highest Equivalent Price"
as used in this Article shall mean the following:  If there is only one class of
capital stock of the Corporation issued and outstanding, the Highest Per Share
Price shall mean the highest price that can be determined to have been paid at
any time by the Substantial Shareholder involved in the Business Combination for
any share or shares of that class of capital stock. If there is more than one
class of capital stock of the Corporation issued and outstanding, the Highest
Equivalent Price shall mean, with respect to each class and series of capital
stock of the Corporation, the amount determined by a majority of the Continuing
Directors, on whatever basis they believe is appropriate, to be the highest per
share price equivalent to the highest price that can be determined to have been
paid at any time by the Substantial Shareholder for any share or shares of any
class or series of capital stock of the Corporation. The Highest Per Share Price
and the Highest Equivalent Price shall include any brokerage commissions,
transfer taxes and soliciting dealers' fees paid by a Substantial Shareholder
with respect to the shares of capital stock of the Corporation acquired by such
Substantial Shareholder.  In the case of any Business Combination with a
Substantial Shareholder, the Continuing Directors shall determine the Highest
Per Share Price or the Highest Equivalent Price for each class and series of the
capital stock of the Corporation.  The Highest Per Share Price and Highest
Equivalent Price shall be appropriately adjusted to reflect the occurrence of
any reclassification, recapitalization, stock split, reverse stock split or
other readjustment in the number of outstanding shares of capital stock of the
Corporation, or the declaration of a stock dividend thereon, between the last
date upon which the Substantial Shareholder paid the Highest Per Share Price of
Highest Equivalent Price and the effective date of the merger or consolidation
or the date of distribution to stockholders of the Corporation of the proceeds
from the sale of all or substantially all of the assets of the Corporation.

          (9) The term "Substantial Part" shall mean 15 percent or more of the
fair market value of the total assets of the Person in question, as reflected on
the most recent balance sheet of such Person existing at the time the
stockholders of the Corporation would be required to approve or authorize the
Business Combination involving the assets constituting any such Substantial
Part.

          (10) The term "Affiliate," used to indicate a relationship with a
specified Person, shall mean a Person that directly, or indirectly through one
or more intermediaries, controls, or is controlled by, or is under common
control with, the Person specified.

          (11) The term "Associate," used to indicate a relationship with a
specified Person, shall mean (a) any entity of which such specified Person is an
officer or partner or is, directly or indirectly, the beneficial owner of 10
percent or more of any class of equity securities, (b) any trust or other estate
in which such specified Person has a substantial beneficial interest or as to
which such specified Person serves as trustee or in a similar fiduciary
capacity, (c) any relative or spouse of such specified Person, or any relative
of such spouse, who has the same home as such specified Person or who is a
director or officer of the Corporation or any of its subsidiaries, and (d) any
Person who is a director or officer of such specified entity or any of its
parents or subsidiaries (other than the Corporation or an entity controlled by
or under common control with the Corporation).

     C.   For the purposes of this Article, a majority of the Continuing
Directors shall have the power to make a good faith determination, on the basis
of information known to them, of:  (a) the number of shares of Voting Stock that
any Person Beneficially Owns, (b) whether a Person is an Affiliate or Associate
of another, (c) whether a Person has an agreement, contract, arrangement or
understanding with another as to the matters referred to in subparagraph B(1)(h)
or B(3) hereof, (d) whether the assets subject to any Business Combination
constitute a Substantial Part, (e) whether any Business Combination is one in
which a Substantial Shareholder has an interest (except proportionately as a
stockholder of the Corporation), and (f) such other matters with respect to
which a determination is required under this Article.

     D.   The provisions set forth in this Article may not be amended, altered,
changed or repealed in any respect unless such action is approved by the
affirmative vote of the holders of not less than a majority of the outstanding
shares of Voting Stock of the Corporation at a meeting of the shareholders duly
called for the consideration of such amendment, alteration, change or repeal;
provided, however, that if there is a Substantial Shareholder who is not a
Continuing Director, such action must also be approved by the affirmative vote
of the holders of not less than 70 percent of the outstanding shares of Voting
Stock.

between StanCorp Financial Group, Inc., an Oregon corporation (the "Company"),
and ChaseMellon Shareholder Services, L.L.C. (the "Rights Agent").

                                   ----------

     WHEREAS, the Board of Directors of the Company authorized and declared a
dividend of one Right for each share of Common Stock (as such terms are
hereinafter defined) of the Company outstanding on April 21, 1999 (the "Record
Date"), and has authorized the issuance of one Right with respect to each share
of Common Stock issued by the Company between the Record Date and the earliest
of the Distribution Date, the Redemption Date or the Final Expiration Date (as
such terms are hereinafter defined), with each Right initially representing the
right to purchase one one-hundredth of a share of Preferred Stock (as
hereinafter defined) having the rights, powers and preferences set forth in the
form of Amendment to the Company's Articles of Incorporation attached hereto as
Exhibit A, upon the terms and subject to the conditions herein set forth (the

Person shall not include the Company, any Subsidiary (as such term is
hereinafter defined) of the Company or any employee benefit plan of the Company
or of any Subsidiary of the Company, or any entity holding shares of Common
Stock for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall be deemed to be an "Acquiring Person" either (i) as
the result of an acquisition 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 Common Stock of the
Company then outstanding; provided, however, that if a Person shall become the
                          --------  -------
Beneficial Owner of 15% or more of the Common Stock then outstanding by
reason of share purchases by the Company and shall, after such share purchases
by the Company, become the Beneficial Owner of any additional shares of Common
Stock, then such Person shall be deemed to be an "Acquiring Person," or (ii) if
the Board of Directors of the Company determines in good faith that a Person who
would otherwise be an "Acquiring

     conversion rights, exchange rights, rights, warrants or options, or
     otherwise; or
 
               (iii) which are beneficially owned, directly or indirectly, by
     any other Person (or any Affiliate or Associate thereof) with which such
     Person (or any of such Person's Affiliates or Associates) has any agreement
     arrangement or understanding, whether or not in writing, for the purpose of
     acquiring, holding, voting or disposing of any securities of the Company;

provided, however, that nothing in this paragraph (e) shall cause a person to be

the "Beneficial Owner" of, or to "beneficially own," (A) any securities that may
be issued on the exercise of Rights, (B) any security if the agreement,

limitation any rights or warrants to acquire additional shares of such common

benefit of holders of such shares, or to share in the benefits of any agreements
or other arrangements for the benefit of such holders), whether or not such
rights are yet exercisable, and together with any other securities which are

of the close of business on the Distribution Date, at the address of such holder
shown on the records of the Company, a Rights Certificate, in substantially the
form of Exhibit B hereto (a "Rights Certificate"), evidencing one Right for each
share of Common Stock so held, subject to adjustment as provided herein. In the
event that an adjustment in the number of Rights per share of Common Stock has
been made pursuant to Section 11(h), at the time the Rights Certificates are
distributed the Company shall make the necessary and appropriate rounding
adjustments pursuant to Section 14(a) so that Rights Certificates are
distributed representing only whole numbers of Rights and cash is paid in lieu
of fractional Rights. As of and after the Distribution Date, the Rights will be
evidenced solely by such Rights Certificates.
 
           (b) As soon as practicable following the Record Date, the Company
will send a copy of a Summary of Rights to Purchase Preferred Stock, in
substantially the form of Exhibit C (the "Summary of Rights"), by first-class,
postage-prepaid mail, to each record holder of shares of Common Stock as of the
Close of Business on the Record Date, at the address of such holder shown on the
records of the Company.
 
           (c) All Common Stock certificates which are issued, either upon an
original issuance by the Company or upon a transfer by a holder, after the
Record Date but prior to the earliest of the Distribution Date, the Redemption
Date or the Final Expiration Date, shall have impressed on, printed on, written
on or otherwise affixed to them the following legend:
 
           This certificate also evidences and entitles the holder
           hereof to certain rights set forth in a Rights Agreement
           between StanCorp Financial Group, Inc. (the "Company") and
           ChaseMellon Shareholder Services, L.L.C. dated as of April 21, 1999
           (the "Rights Agreement"), the terms of which are incorporated herein
           by reference and a copy of which is on file at the principal
           executive 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 without charge after receipt of a
           written request therefor. Under certain circumstances, Rights
           beneficially owned by Acquiring Persons or their Affiliates or
           Associates (as such terms are defined in the Rights Agreement), and
           Rights previously owned by such Persons, may become null and void.

     4.    Form of Rights Certificates.
           ---------------------------
 
           (a) The Rights Certificates (and the form of election to purchase and
form of assignment to be printed on the reverse thereof) shall be substantially
the same as 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 (but which do not affect the rights, duties or
responsibilities of the Rights Agent) and as are not inconsistent with the
provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange on which the Rights may from time to
time be listed, or to conform to usage. Subject to the provisions of Section 11
and Section 22, the Rights Certificates, whenever distributed, shall entitle the
holders thereof to purchase for the Purchase Price such number of one one-
hundredths of a share of Preferred Stock as shall be set forth therein, but the
amount and type of securities purchasable upon exercise and the Purchase Price
shall be subject to adjustment as provided herein.

           (b) Any Rights Certificate issued pursuant to Section 3 hereof that
represents Rights beneficially owned by (i) an Acquiring Person or any Associate
or Affiliate of an Acquiring Person, (ii) any other Person if such Rights
formerly were beneficially owned by an Acquiring Person (or by an Associate or
Affiliate of such Acquiring Person) at a time after the Acquiring Person became
an Acquiring Person, or (iii) a transferee of Rights from an Acquiring Person
(or from any Associate or Affiliate thereof) who became a transferee prior to or
concurrently with the Acquiring Person becoming an Acquiring Person and receives
such Rights pursuant to either (A) a transfer (whether or not for consideration)
from the Acquiring Person (or its Affiliate or Associate) to holders of equity
interests in such Acquiring Person (or its Affiliate or Associate) or to any
Person with whom such Acquiring Person (or its Affiliate or Associate) has any
continuing agreement, arrangement or understanding regarding the transferred
Rights, or (B) a transfer which the Board of Directors has determined is part of
a plan, arrangement or understanding that has as a primary purpose or effect the
avoidance of Section 7(e), and any Rights Certificate issued pursuant to Section
6, 7(d) or 22 upon transfer, exchange, replacement or adjustment of any other
Rights Certificate referred to in this sentence, shall contain the following
legend:
 
           The Rights represented by this Rights Certificate are or
           were beneficially owned by a Person who was an Acquiring
           Person or an Affiliate or Associate of an Acquiring
           Person (as such terms are defined in the Rights
           Agreement). Accordingly, this Rights Certificate and the
           Rights represented hereby may become null and void in the
           circumstances specified in Section 7(e) of the Rights
           Agreement;

provided, however, that the Rights Agent shall not have any responsibility to
- --------  -------                                                            
ascertain the existence of facts that would require the imposition of such
legend and shall be required to 

                                       7
<PAGE>
 
impose such legend only if instructed to do so by the Company or if a holder
fails to certify upon transfer or exchange in the space provided on the Rights
Certificate that such holder is not an Acquiring Person or an Affiliate or
Associate of an Acquiring Person.

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

     Following the Distribution Date and receipt by the Rights Agent of all
relevant information, the Rights Agent will keep or cause to be kept, at its
offices designated for such purposes, books for registration and transfer of the
Rights Certificates issued hereunder.  Such books shall show the names and
addresses of the respective holders of the Rights Certificates, the number of
Rights evidenced on its face by each of the Rights Certificates and the date of
each of the Rights Certificates.

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

          (a) Subject to the provisions of Sections 4(b), 7(e) and 14, at any
time after the Close of Business on the Distribution Date, and at or prior to
the Close of Business on the earlier of the Redemption Date or the Final
Expiration Date, any Rights Certificate or Certificates may be transferred,
split up, combined or exchanged for another Rights Certificate or Certificates,
entitling the registered holder to purchase a like number of shares of Preferred
Stock or other securities or property as the Rights Certificate or Certificates
surrendered then entitled such holder 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 office of the Rights Agent designated for
such purpose. Neither the Rights Agent nor the Company shall be obligated to
take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate until the registered holder shall have completed and signed
the certificate contained in the form of assignment on 

                                       8
<PAGE>
 
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 or the
Rights Agent shall reasonably request. Thereupon the Rights Agent shall, subject
to Sections 4(b), 7(e) and 14, 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. The Rights Agent shall
have no duty or obligation to take any action under any section of this
Agreement which requires the payment by a Rights holder of applicable taxes and
governmental charges unless and until the Rights Agent is satisfied that all
such taxes and/or charges have been paid.

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

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

          (a) At any time after the Distribution Date and at or prior to the
earlier of (i) the Close of Business on April 20, 2009 (the "Final Expiration
Date") or (ii) the time at which the Rights are redeemed as provided in Section
23 (the "Redemption Date"), subject to Section 7(e), 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 Sections 9(c), 11(a)(iii)) and 23(a) in whole or in
part upon surrender of the Rights Certificate, with the form of election to
purchase and certificate on the reverse side thereof duly executed, to the
Rights Agent at the office of the Rights Agent designated for such purpose,
together with payment of the Purchase Price for each Right that is exercised.

          (b) The Purchase Price to be paid on exercise of each Right shall
initially be $118.75 and shall be payable in lawful money of the United States
of America in accordance with paragraph (c) below.  Each Right shall initially
entitle the holder to acquire one one-hundredth of a share of Preferred Stock
upon exercise of the Right.  The Purchase Price and the number of shares of
Preferred Stock or other securities or assets for which a Right is exercisable
shall be subject to adjustment as provided in Sections 11 and 13.

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the shares to be purchased and an amount equal
to any applicable tax or governmental 

                                       9
<PAGE>
 
charge in cash, or by certified check or cashier's check payable to the order of
the Company, the Rights Agent shall, subject to Section 20(k), thereupon
promptly (i) requisition from any transfer agent of the Preferred Stock (or make
available, if the Rights Agent is the transfer agent) certificates for the
number of shares of Preferred Stock to be purchased and the Company hereby
authorizes its transfer agent to comply with all such requests, (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of issuance of fractional shares in accordance with Section 14, (iii) after
receipt of the certificates for Preferred Stock cause the same to be delivered
to or upon the order of the registered holder of such Rights Certificate,
registered in such name or names as may be designated by such holder and (iv)
when appropriate, after receipt, deliver such cash to or upon the order of the
registered holder of such Rights Certificate. In the event that the Company is
obligated to issue other securities (including, but not limited to, debt
securities) of the Company, and/or distribute other property pursuant to Section
11, the Company covenants that it will make all arrangements necessary so that
such other securities and/or property are available for distribution by the
Rights Agent, if and when necessary to comply with this Agreement.

          (d) In case the registered holder of any Rights Certificate shall
exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Rights Certificate or to
his duly authorized assigns, subject to the provisions of Section 6 and Section
14.

          (e) Notwithstanding any other provision of this Agreement, from and
after the occurrence of a Stock Acquisition Date, any Rights beneficially owned
by (i) an Acquiring Person, or any Associate or Affiliate of an Acquiring
Person, (ii) any other Person if such Rights formerly were beneficially owned by
an Acquiring Person (or by an Associate or Affiliate of such Acquiring Person)
at a time after such Acquiring Person became an Acquiring Person, or (iii) a
transferee of Rights from an Acquiring Person (or from any Associate or
Affiliate thereof) who became a transferee prior to or concurrently with the
Acquiring Person becoming an Acquiring Person and receives such Rights pursuant
to either (A) a transfer (whether or not for consideration) from the Acquiring
Person (or its Affiliate or Associate) to holders of equity interests in such
Acquiring Person (or its Affiliate or Associate) or to any Person with whom the
Acquiring Person (or its Affiliate or Associate) has any continuing agreement,
arrangement or understanding regarding the transferred Rights, or (B) a transfer
which the Board of Directors has determined is part of a plan, arrangement or
understanding that has as a primary purpose or effect the avoidance of this
Section 7(e), shall become null and void and any holder of such Rights shall
thereafter have no right to exercise such Rights under any provision of this
Agreement.  The Company shall promptly notify the Rights Agent of the
applicability of this Section 7(e) and shall use all reasonable efforts to
ensure that the provisions of this Section 7(e) and of Section 4(b) are complied
with, but neither the Company nor the Rights Agent shall have any liability to
any holder of Rights Certificates or any other Person as a result of the
Company's failure to make any determinations with respect to an Acquiring
Person, or any of its Affiliates, Associates or transferees hereunder.

                                       10
<PAGE>
 
          (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) properly completed and signed the certificate contained in the form of
election to purchase set forth on the reverse side of the surrendered Right
Certificate 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 or the Rights Agent shall reasonably request.

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

      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 Preferred Stock (and,
following the occurrence of a Stock Acquisition Date or a Section 13 Event, out
of its authorized and unissued shares of Common Stock and/or other securities),
the number of shares of Preferred Stock (and, following the occurrence of a
Stock Acquisition Date or a Section 13 Event, Common Stock and/or other
securities) that, as provided in this Agreement, will be sufficient to permit
the exercise in full of all outstanding Rights; provided, however, that shares
issuable pursuant to Section 11(a)(ii) shall be reserved only following the
occurrence of an event described in that section.

          (b) If any shares of Preferred Stock are listed on a national
securities exchange, and so long as the shares of Preferred Stock (and,
following the occurrence of a Stock Acquisition Date or a Section 13 Event,
Common Stock and/or other securities) issuable and deliverable upon the exercise
of the Rights may be listed on that exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable, all
shares reserved for such issuance to be listed on the exchange upon official
notice of issuance upon exercise.

          (c) The Company shall use its best efforts (i) to file, as soon as
practicable following a Stock Acquisition Date and the determination by the
Company in accordance with 

                                       11
<PAGE>
 
Section 11(a)(iii) of the consideration to be delivered by the Company upon
exercise of the Rights, or as soon as is required by law following the
Distribution Date, as the case may be, a registration statement under the Act
with respect to the securities purchasable upon exercise of the Rights on an
appropriate form, (ii) to cause such registration statement to become effective
as soon as practicable after such filing, and (iii) to cause such registration
statement to remain effective (with a prospectus at all times meeting the
requirements of the Act) until the earlier of (A) the date as of which the
Rights are no longer exercisable for such securities, and (B) the date of the
expiration of the Rights. The Company will also take such action as may be
appropriate under or to ensure compliance with, the securities or "blue sky"
laws of the various states in connection with the exercisability of the Rights.
The Company may temporarily suspend the exercisability of the Rights, for a
period of time not to exceed 90 days after the date the Company first becomes
obligated to use its best efforts to file a registration statement as set forth
in clause (i) of the first sentence of this Section 9(c), 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. The Company
will notify the Rights Agent whenever it makes a public announcement pursuant to
Section 9(c) and will provide the Rights Agent with a copy of such announcement.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction, unless the requisite qualification
in such jurisdiction shall have been obtained and until a registration statement
has been declared effective.

          (d) The Company covenants and agrees that it will take all such action
as may be necessary to ensure that all shares of Preferred Stock (and, following
the occurrence of a Stock Acquisition Date or Section 13 Event, Common Stock
and/or other securities) delivered upon exercise of Rights shall, at the time of
delivery of the certificates for such shares of such shares (subject to payment
of the Purchase Price), be duly and validly authorized and issued and fully paid
and nonassessable shares.

          (e) The Company further covenants and agrees that it will pay when due
and payable any and all taxes and governmental charges which may be payable in
respect of the issuance or delivery of the Rights Certificates or of any shares
of Preferred Stock or other securities upon the exercise of Rights.  The Company
shall not, however, be required to pay any tax or governmental charge which may
be payable in respect of any transfer, split-up, combination or exchange of
Rights Certificates, or any issuance or delivery of certificates for shares in a
name other than that of the registered holder of the Rights Certificate
evidencing Rights surrendered for exercise, and shall not be required to issue
or deliver any certificates for shares upon the exercise of any Rights until any
such tax or governmental charge shall have been paid (any such tax or
governmental charge 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.

      10. Preferred Stock Record Date.  Each Person in whose name any
          ---------------------------                                
certificate for a number of one one-hundredths 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 any applicable transfer taxes or governmental charges) 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 shareholder of the Company with respect to shares for which the
Rights shall be exercisable, including, without limitation, to receive dividends
or other distributions or to exercise any preemptive rights, and shall not be
entitled to receive any notice of any proceedings of the Company, except as
provided herein.

      11. Adjustment of Purchase Price, Number of Shares or Number of Rights.
          ------------------------------------------------------------------  
The Purchase Price, the number and kind of securities 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
     Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine
     the outstanding Preferred Stock into a smaller number of shares of
     Preferred Stock or (D) issue any shares of its capital stock in a
     reclassification of the Preferred Stock (including any such
     reclassification in connection with a consolidation or merger in which the
     Company is the continuing or surviving corporation), except as otherwise
     provided in this Section 11(a), the number and kind of shares of capital
     stock issuable at the time of the record date for such dividend or of the
     effective date of such subdivision, combination or reclassification, shall
     be proportionately adjusted so that the holder of any Right exercised after
     such time shall be entitled to receive the aggregate number and kind of
     shares of capital stock which, if such Right had been exercised immediately
     prior to such date and at a time when the Preferred Stock transfer books of
     the Company were open, he or she would have owned upon such exercise and
     been entitled to receive by virtue of such dividend, subdivision,
     combination or reclassification.  The adjustments provided for in this
     Section 11(a)(i) shall be made successively whenever such a dividend is
     declared or paid or such a subdivision, combination or reclassification is
     effected.  If an event occurs which would require an adjustment under both
     this Section 11(a)(i) and Section 11(a)(ii), the adjustment provided for in
     this 

                                       13
<PAGE>
 
     Section 11(a)(i) shall be in addition to, and shall be made prior to,
     any adjustment required pursuant to Section 11(a)(ii).

               (ii) In the event that a Stock Acquisition Date occurs, proper
     provision shall be made so that each holder of a Right, except as provided
     below and in Section 7(e), shall thereafter have a right to receive, upon
     exercise thereof and payment of the Purchase Price in accordance with the
     terms of this Agreement, in lieu of a number of one one-hundredths of a
     share of Preferred Stock, such number of shares of Common Stock as shall
     equal the result obtained by dividing the then current Purchase Price by 50
     percent of the Current Per Share Market Price of the Common Stock
     (determined pursuant to Section 11(d)) on the Stock Acquisition Date (such
     number of shares being the "Adjustment Shares").

               (iii)  In the event the number of shares of Common Stock which
     are authorized by the Company's articles of incorporation but not
     outstanding or reserved for issuance for purposes other than upon exercise
     of the Rights are not sufficient to permit the exercise in full of the
     Rights 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 then current 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 applicable Purchase Price,
     (3) shares of Common Stock or other equity securities of the Company
     (including, without limitation, shares, or units of shares, of preferred
     stock that the Board of Directors of the Company has deemed to have the
     same value as shares of Common Stock ("Common Stock Equivalents")), (4)
     debt securities of the Company, (5) other assets, or (6) any combination of
     the foregoing, having an aggregate value equal to the Current Value, 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,
                                                             --------  ------- 
     if the Company shall not have made adequate provision to deliver value
     pursuant to clause (B) above within 30 days following the Stock Acquisition
     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 30-day period set forth above may be extended to the extent necessary,
     but not more than 90 days after the Stock Acquisition Date, in order that
     the Company may seek shareholders approval for the authorization of such
     additional shares (such period, as it may be extended as so permitted, the
     "Substitution Period").  To the extent the Company determines that some
     action must be taken pursuant to the first or second 

                                       14
<PAGE>
 
     sentences of this Section 11(a)(iii), the Company (x) shall provide that
     such action shall apply uniformly to all outstanding Rights other than
     those that are null and void as provided in Section 7(e), and (y) may
     suspend the exercisability of the Rights until the expiration of the
     Substitution Period in order to seek any authorization of additional shares
     and/or to decide the appropriate form of distribution to be made pursuant
     to 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 (with prompt notice by the Company of such announcements to the
     Rights Agent). For purposes of this Section 11(a)(iii), the value of the
     Common Stock shall be the Current Per Share Market Price (as determined
     pursuant to Section 11(d) hereof) of the Common Stock on the date of the
     Stock Acquisition Date and the value of any Common Stock Equivalent shall
     be deemed to have the same value as the Common Stock on such date.

          (b) In case the Company shall at any time after the date of this
Agreement fix a record date for the issuance of rights, options or warrants to
all holders of Preferred Stock entitling them (for a period expiring within 45
calendar days after such record date) to subscribe for or purchase Preferred
Stock (or shares having the same rights, privileges and preferences as the
Preferred Stock ("Preferred Stock Equivalents")) or securities convertible into
Preferred Stock or Preferred Stock Equivalents at a price per share of Preferred
Stock or Preferred Stock Equivalent (or having a conversion price per share, if
a security convertible into Preferred Stock or Preferred Stock Equivalents) less
than the then Current Per Share Market Price of the Preferred Stock (as defined
in Section 11(d)) on such record date, the number of shares of Preferred Stock
for which each Right shall be exercisable after such record date shall
determined by multiplying the number of shares of Preferred Stock for which each
Right was exercisable 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 additional shares of Preferred Stock
and/or Preferred Stock Equivalents to be offered for subscription or purchase
(or into which the convertible securities so to be offered are initially
convertible) and the denominator 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 Preferred Stock Equivalents so to be offered (and/or
the aggregate initial conversion price of convertible securities so to be
offered) would purchase at such Current Per Share Market Price.  In case such
subscription price may be paid in a consideration part or all of which shall be
in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and the holders of the Rights.  Preferred 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 number of shares of Preferred Stock for which
each Right shall 

                                       15
<PAGE>
 
be exercisable shall be readjusted to be the number of shares of Preferred Stock
for which each Right would then be exercisable if such record date had not been
fixed; and to the extent such rights, options or warrants are issued but not
exercised prior to their expiration, the number of shares for which each Right
shall be exercisable shall be readjusted to be the number which would have
resulted from the adjustment provided for in this Section 11(b) if only the
rights or warrants that were exercised had been issued.

          (c)  (i)  In case the Company shall at any time after the date of this
     Agreement fix a record date for the making of a distribution to all holders
     of Preferred Stock (including any such distribution made in connection with
     a consolidation or merger in which the Company is the continuing or
     surviving corporation) of evidences of indebtedness or assets (other than a
     regular quarterly cash dividend or a dividend payable in shares of
     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)), the number of shares of Preferred Stock for
     which each Right shall be exercisable after such record date shall be
     determined by multiplying the number of shares of Preferred Stock for which
     each Right was exercisable immediately prior to such record date by a
     fraction, the numerator of which shall be the then Current Per Share Market
     Price of the Preferred Stock (as defined in Section 11(d)) on such record
     date, and the denominator of which shall be such Current Per Share Market
     Price of the Preferred Stock, less the fair market value (as determined in
     good faith by the Board of Directors, whose determination shall be
     described in a statement filed with the Rights Agent and shall be binding
     on the Rights Agent and the holders of the Rights) of the portion of the
     assets or evidences of indebtedness so to be distributed or of such
     subscription rights or warrants applicable to one share of Preferred Stock.
     Such adjustments shall be made successively whenever such a record date is
     fixed; and in the event that such distribution is not so made, the number
     of shares of Preferred Stock for which each Right shall be exercisable
     shall be readjusted to be the number of shares of Preferred Stock for which
     each Right would then be exercisable if such record date had not been
     fixed.

               (ii) In case the Company shall at any time after the date of this
     Agreement fix a record date for the making of a distribution to all holders
     of Common Stock (including any such distribution made in connection with a
     consolidation or merger in which the Company is the continuing or surviving
     corporation) of evidences of indebtedness or assets (other than a regular
     quarterly cash dividend or a dividend payable in shares of Common Stock) or
     subscription rights or warrants (excluding those referred to in Section
     11(h)(ii)), the number of shares of Preferred Stock for which each Right
     shall be exercisable after such record date shall be determined by
     multiplying the number of shares of Preferred Stock for which each Right
     was exercisable immediately prior to such record date by a fraction, the
     numerator of which shall be the then Current Per Share Market Price of the
     Common Stock (as defined in Section 11(d)) on such record date, and the
     denominator of which shall be such Current Per Share Market 

                                       16
<PAGE>
 
     Price of the Common Stock, less the fair market value (as determined in
     good faith by the Board of Directors, whose determination shall be
     described in a statement filed with the Rights Agent and shall be binding
     on the Rights Agent and the holders of the Rights) of the portion of the
     assets or evidences of indebtedness so to be distributed or of such
     subscription rights or warrants applicable to one share of Common Stock.
     Such adjustments shall be made successively whenever such a record date is
     fixed; and in the event that such distribution is not so made, the number
     of shares of Preferred Stock for which each Right shall be exercisable
     shall be readjusted to be the number of shares of Preferred Stock for which
     each Right would then be exercisable if such record date had not been
     fixed.

          (d)  (i)  For the purpose of any computation hereunder, the "Current
     Per Share Market Price" of common stock (including Common Stock) on any
     date shall be deemed to be the average of the daily closing prices per
     share of the common stock for the 30 consecutive Trading Days (as such term
     is hereinafter defined) immediately prior to but not including such date;
                                                                              
     provided, however, that in the event the Current Per Share Market Price of
     --------  -------                                                         
     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 such common stock or securities convertible into
     such common stock, or (B) any subdivision, combination or reclassification
     of such common stock, and prior to the expiration of 30 Trading Days after
     but not including the ex-dividend date for such dividend or distribution,
     or the record date for such subdivision, combination or reclassification,
     then, and in each such case, the Current Per Share Market Price shall be
     appropriately adjusted to take into account such event.  The closing price
     for each day shall be the last sale price as reported by the New York Stock
     Exchange (the "NYSE") or such other system then in use, or, if on any such
     date the common stock is not quoted by any such organization, the average
     of the closing bid and asked prices as furnished by a professional market
     maker making a market in the common stock selected by a majority of the
     Board of Directors.  The term "Trading Day" shall mean a day on which the
     principal national securities exchange on which the common stock is listed
     or admitted to trading is open for the transaction of business or, if the
     common stock is not listed or admitted to trading on any national
     securities exchange, a Business Day.  If the common stock is not publicly
     held or so listed or traded for the 30-day period, "Current Per Share
     Market Price" shall mean the fair value per share as determined in good
     faith by the Board of Directors of the Company, whose 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
     Per Share Market Price" 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 Per
     Share Market Price of Preferred Stock cannot be determined in the manner
     provided above or if the Preferred Stock is not publicly held 

                                       17
<PAGE>
 
     or listed or traded in a manner described in clause (i) of this Section
     11(d), the "Current Per Share Market Price" of Preferred Stock shall be
     conclusively deemed to be an amount equal to the Current Per Share Market
     Price of the Common Stock multiplied by the Adjustment Number as that term
     is defined in Section 2 of the Amendment to the Company's Articles of
     Incorporation, as amended, designating the Preferred Stock (initially 100).
     If neither the Common Stock nor the Preferred Stock is publicly held or so
     listed or traded, "Current Per Share Market Price" of 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 conclusive for all
     purposes. For all purposes of this Agreement, the current market price of
     one one-hundredth of a share of Preferred Stock shall be equal to the
     Current Per Share Market Price of one share of Preferred Stock divided by
     100.

          (e) No adjustment in the Purchase Price or the number of shares for
which a Right is exercisable shall be required unless such adjustment would
require an increase or decrease of at least one percent in the Purchase Price or
the number of shares for which a Right is exercisable; provided, however, that
                                                       --------  -------      
any adjustments which by reason of this Section 11(e) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment.  All calculations under this Section 11 shall be made to the nearest
cent or to the nearest ten-thousandth of a share of Common Stock or one-
millionth of a share of Preferred Stock, as the case may be.  Notwithstanding
the first sentence of this Section 11(e), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three years from the
date of the transaction which requires such adjustment or (ii) the date of the
expiration of the right to exercise any Rights.

          (f) If as a result of an adjustment made pursuant to Section 11(a),
the holder of any Right thereafter exercised shall become entitled to receive
any shares of capital stock of the Company other than Preferred Stock,
thereafter the number of such other shares so receivable upon exercise of any
Right shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions with respect to the
Preferred Stock contained in Section 11 and the provisions of Sections 7, 9, 10,
13 and 14 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 or the number of shares of Preferred Stock
for which a Right is exercisable hereunder shall evidence the right to purchase,
at the adjusted Purchase Price, the number of one one-hundredths 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)  (i)  In the event the Company shall, after the date of this
     Agreement and prior to the Distribution Date, (A) declare a dividend on the
     Common Stock payable in Common Stock, (B) subdivide the outstanding Common
     Stock, (C) combine

                                       18
<PAGE>
 
the outstanding Common Stock into a smaller number of shares of Common Stock, or
(D) issue any shares of Common Stock in a reclassification of the Common Stock
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), the
number of Rights associated with each share of Common Stock then outstanding,
and the number of Rights to be associated with each share of Common Stock which
may thereafter become outstanding prior to the Distribution Date, shall be
proportionately adjusted so that the number of Rights 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 number of shares of Common Stock outstanding immediately prior to such event
and the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such event.

               (ii) In the event the Company shall, after the date of this
Agreement and prior to the Distribution Date, fix a record date for the issuance
of rights, options or warrants to all holders of Common Stock entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Common Stock or securities convertible into Common
Stock at a price per share of Common Stock (or having a conversion price per
share, if a security convertible into Common Stock) less than the then Current
Per Share Market Price of the Common Stock (as defined in Section 11(d)) on such
record date, the number of Rights associated with each share of Common Stock
then outstanding, and the number of Rights to be associated with each share of
Common Stock which may thereafter become outstanding prior to the Distribution
Date, shall be proportionately adjusted so that the number of Rights associated
with each share of Common Stock after such record date shall be determined by
multiplying the number of Rights associated with each share of Common Stock
immediately prior to such record date by a fraction, the numerator of which
shall be the number of shares of Common Stock outstanding on such record date
plus the number of shares of Common Stock which the aggregate offering price of
the total number of shares of Common 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 Per Share Market Price and the
denominator of which shall be the number of shares of Common Stock outstanding
on such record date plus the number of additional shares of Common 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 in a consideration part or all of which shall be in a form other than
cash, the value of such consideration shall be as determined in good faith by
the Board of Directors, whose determination shall be described in a statement
filed with the Rights Agent and conclusive and binding for all purposes. Common
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. In the event that such
rights, options or warrants are not so issued, the

                                       19
<PAGE>
 
     number of Rights associated with each share of Common Stock shall be
     readjusted to be the number of Rights that would have been associated with
     each share of Common Stock if such record date had not been fixed; and to
     the extent such rights, options or warrants are issued but not exercised
     prior to their expiration, the number of Rights associated with each share
     shall be readjusted to be the number which would have resulted from the
     adjustment provided for in this Section 11(h)(ii) if only the rights,
     options or warrants that were exercised had been issued.

               (iii)  Notwithstanding the foregoing, the adjustments provided
     for in this Section 11(h) shall not be made if the Company exercises its
     election provided for in Section 11(i).

          (i) The Company may elect on or after the date of any event described
in clauses (A) through (D) of Section 11(h)(i) or described in Section
11(h)(ii), if such event occurs before the Distribution Date (a "Section 11(h)
Event"), to adjust the Purchase Price and the number of shares of Preferred
Stock purchasable upon the exercise of a Right in substitution for any
adjustment under Section 11(h) in the number of Rights associated with each
share of Common Stock.  If such election is made, (i) the number of Rights
associated with each share of Common Stock prior to the Section 11(h) Event
shall be maintained after the Section 11(h) Event, (ii) any new shares of Common
Stock issued in the Section 11(h) Event shall, as provided in Section 3(a), have
issued with it the number of Rights associated with each share of Common Stock
outstanding, and (iii) any combination of shares of Common Stock into a smaller
number of shares in the Section 11(h) Event shall result in a similar
combination of the associated Rights. The Purchase Price and the number of
Shares of Preferred Stock purchasable upon exercise of a Right after such
adjustment shall be determined by multiplying the Purchase Price and the number
of Shares of Preferred Stock purchasable upon exercise of a Right, respectively,
in effect immediately prior to such adjustment by a fraction, the numerator of
which shall be the number of Rights that would have been associated with each
share of Common Stock after the Section 11(h) Event if the Company had not
exercised its election provided for in this Section 11(i) and the denominator of
which shall be the number of Rights associated with each share of Common Stock
immediately prior to the Section 11(h) Event.  To the extent the number of
Rights that would have been associated with each share of Common Stock if the
Company had not exercised its election provided for in this Section 11(i) may be
readjusted as provided in the last sentence of Section 11(h)(ii), the Purchase
Price and number of shares of Preferred Stock purchasable upon exercise of a
Right shall be similarly readjusted.

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

                                       20
<PAGE>
 
          (k) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price or the number of one one-hundredths of a share
of Preferred Stock for which a Right is exercisable be made effective as of a
record date for a specified event, the Company may elect to defer (with prompt
notice of such deferral to the Rights Agent) until the occurrence of such event
the issuance to the holder of any Right exercised after such record date the
number of one one-hundredths of a share of Preferred Stock and other capital
stock or securities of the Company, if any, issuable upon such exercise over and
above the number of one one-hundredths 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 and the number of one one-hundredths of a
share of Preferred Stock for which a Right is exercisable 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 upon the occurrence of the event requiring
such adjustment.

          (l) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment the Board of Directors shall
determine to be advisable in order that any consolidation or subdivision of the
Preferred Stock, issuance wholly for cash of any Preferred Stock at less than
the current market price, issuance wholly for cash of Preferred Stock or
securities which by their terms are convertible into or exchangeable for shares
of Preferred Stock, dividends on Preferred Stock payable in Preferred Stock or
issuance of rights, options or warrants referred to in Section 11(b), hereafter
made by the Company to holders of its Preferred Stock shall not be taxable to
such shareholders or shall reduce the taxes payable by such shareholders.

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

      12. Certificate of Adjusted Purchase Price or Number of Shares.  Whenever
          ----------------------------------------------------------           
an adjustment is made as provided in Sections 11 and 13, the Company shall
promptly (a) prepare a certificate setting forth such adjustment and a brief
statement of the facts and computations accounting for such adjustment, (b) file
with the Rights Agent and with each transfer agent for the Preferred Stock and
the Common Stock a copy of such certificate and (c) mail a brief summary thereof
to each holder of Rights in accordance with Section 25.  The Rights Agent shall
be fully protected in relying on any such certificate and on any adjustment
therein contained and shall have no duty with respect to and shall not be deemed
to have knowledge of any adjustment unless and until it shall have received such
a certificate.

                                       21
<PAGE>
 
      13. Consolidation, Merger or Sale or Transfer of Assets or Earning Power.
          -------------------------------------------------------------------- 

          (a) In the event that, following the Distribution Date, directly or
indirectly,

               (i) the Company shall consolidate with, or merge with and into,
     any other Person (other than a Subsidiary of the Company in a transaction
     that complies with Section 11(m)) and the Company shall not be the
     continuing or surviving corporation of such consolidation or merger,

               (ii) any Person shall acquire shares of Common Stock of the
     Company in a share exchange,

               (iii)  any Person (other than a Subsidiary of the Company in a
     transaction that complies with Section 11(m)) shall consolidate with the
     Company, or merge with and into the Company and the Company shall be the
     continuing or surviving corporation of such consolidation or merger and, in
     connection with such consolidation or merger, all or part of the
     outstanding Common Stock shall be changed into or exchanged for stock or
     other securities of any other Person or cash or any other property, or

               (iv) the Company shall sell or otherwise transfer (or one or more
     of its Subsidiaries shall sell or otherwise transfer), in one or more
     transactions, assets or earning power aggregating 50 percent or more of the
     assets or earning power of the Company and its Subsidiaries (taken as a
     whole) to any Person other than the Company or one or more of its wholly
     owned Subsidiaries in a transaction that complies with Section 11(m),

then, and in each such case, proper provision shall be made so that (A) each
- ----                                                                        
holder of a Right (except as otherwise provided in Section 7(e)) shall
thereafter have the right to receive, upon the exercise thereof and payment of
the Purchase Price in accordance with the terms of this Agreement, such number
of validly authorized and issued, fully paid, nonassessable and freely tradeable
shares of common stock of the Principal Party (as 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 dividing the then current
Purchase Price by 50 percent of the Current Per Share Market Price of the common
stock of the Principal Party (determined pursuant to Section 11(d)) on the date
of consummation of the Section 13 Event, (B) the Principal Party shall
thereafter be liable for, and shall assume, by virtue of such Section 13 Event,
all the obligations and duties of the Company pursuant to this Agreement, (C)
the term "Company" shall thereafter be deemed to refer to the Principal Party,
it being specifically intended that the provisions of Section 11 shall apply to
the Principal Party only following the first occurrence of a Section 13 Event,
and (D) the Principal Party shall take such steps (including, but not limited
to, the reservation of a sufficient number of shares of its common stock in
accordance with Section 9) in connection with such consummation as may be
necessary to ensure that the 

                                       22
<PAGE>
 
provisions of this Agreement shall thereafter be applicable, as nearly as
reasonably may be, in relation to the common stock thereafter deliverable upon
the exercise of the Rights. The provisions of Section 11(a)(ii) shall be of no
effect following the first occurrence of an event described in Section 13.

          (b) The term "Principal Party" shall mean

               (i) in the case of any transaction described in clause (i), (ii)
     or (iii) 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, or for which shares of Common Stock are exchanged
     in such share exchange, and if no securities are so issued, the Person that
     is the other party to such merger, consolidation or share exchange or, if
     there is more than one such Person, the Person the common stock of which
     has the highest aggregate Current Per Share Market Price (determined
     pursuant to Section 11(d)); and

               (ii) in the case of any transaction described in clause (iv) 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; or, if each Person that is a party to such transaction or
     transactions receives the same portion of the assets or earning power
     transferred pursuant to such transaction or transactions or if the Person
     receiving the largest portion of the assets or earning power cannot be
     determined, whichever Person the common stock of which has the highest
     aggregate current market price (determined pursuant to Section 11(d));

provided, however, that, if the common stock of such Person is not at such time
- --------  -------                                                              
and has not been continuously over the preceding 12-month period registered
under Section 12 of the Exchange Act or such Person is not a corporation, then
(A) if such Person is a direct or indirect Subsidiary of one other Person which
has common stock so registered, "Principal Party" shall refer to such other
Person, (B) if such Person is a direct or indirect Subsidiary of another Person
but is not a direct or indirect Subsidiary of another Person which has common
stock so registered, "Principal Party" shall refer to the ultimate parent entity
of such first-mentioned Person, (C) if such Person is directly or indirectly
controlled by more than one Person, and one or more of such other persons has
common stock so registered, "Principal Party" shall refer to whichever of such
Persons that is the issuer of common stock so registered having the highest
aggregate current market price (determined pursuant to Section 11(d)), and (D)
if such Person is directly or indirectly controlled by more than one Person, and
none of such other Persons have common stock so registered, "Principal Party"
shall refer to whichever ultimate parent entity is the corporation having the
greatest shareholders' equity or, if no such ultimate parent entity is a

          (c) The Company shall not enter into any transaction described in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights.  In
addition, the Company shall not consummate any such transaction unless the
Principal Party shall have a sufficient number of authorized shares of common
stock which have not been issued or reserved for issuance to permit the exercise
in full of the Rights in accordance with this Section 13 and unless prior
thereto the Company and such Principal Party shall have executed and delivered
to the Rights Agent a supplemental agreement providing for the terms set forth
in this Section 13 and further providing that, as soon as practicable after
execution of such agreement, the Principal Party will

               (i) prepare and file a registration statement under the Act with
     respect to 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,
     (B) remain effective (with a prospectus at all times meeting the
     requirements of the Act) until the Final Expiration Date and, as soon as
     practicable following the execution of such agreement, take such action as
     may be required to ensure that any acquisition of such shares of common
     stock upon the exercise of the Rights complies with any applicable state
     security or "blue sky" laws; and

               (ii) 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) In case the Principal Party which is to be a party to a
transaction referred to in this Section 13 has a provision in any of its
authorized securities or in its Articles or Certificate of Incorporation or
Bylaws or other instrument governing its corporate affairs, which provision
would have the effect of (i) causing such Principal Party to issue, in
connection with, or as a consequence of, the consummation of a transaction
referred to in this Section 13, shares of common stock of such Principal Party
at less than the then Current Per Share Market Price (determined pursuant to
Section 11(d)) or securities exercisable for, or convertible into, shares of
common stock of such Principal Party at less than the then Current Per Share
Market Price (other than to holders of Rights pursuant to this Section 13) or
(ii) providing for any special payment, tax or similar provisions in connection
with the issuance of the shares of common stock of such Principal Party pursuant
to the provisions of Section 13; then, in such event, the Company shall not
consummate any such transaction unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing that the provision in question of such
Principal Party shall have been canceled, waived or amended, or that the
authorized securities shall be redeemed, so that the applicable provision will
have no effect in connection with, or as a consequence of, the consummation of
the proposed transaction.

                                       24
<PAGE>
 
          (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 Stock Acquisition
Date, the Rights which have not theretofore been exercised shall thereafter
become exercisable in the manner described in Section 13.  The provisions of
Section 11(a)(ii) shall be of no effect following the first occurrence of a
Section 13 Event.

      14. Fractional Rights and Fractional Shares.
          --------------------------------------- 

          (a) The Company shall not be required to issue fractions of Rights or
to distribute Rights Certificates which evidence fractional Rights.  In lieu of
such fractional Rights, there shall be paid to the registered holders of the
Rights Certificates with regard to which such fractional Right would otherwise
be issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right.  For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable.  The closing price for any day shall be the last
sale price, or, in case no such sale takes place on such day, the average of the
high bid and low asked prices in the over-the-counter market, as reported by the
NYSE or such other system then in use or, if on any such date the Rights are not
quoted by any such organization, the average of the closing bid and asked prices
as furnished by a professional market maker making a market in the Rights
selected by the Board of Directors of the Company.  If on any such date no such
market maker is making a market in the Rights, the fair value of the Rights on
such date as determined in good faith by the Board of Directors of the Company
shall be used.

          (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are integral multiples of one one-
hundredth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock).  In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-hundredths 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 one-hundredth of a share of
Preferred Stock.  For purposes of this Section 14(b), the current market value
of one one-hundredth of a share of Preferred Stock shall be one one-hundredth 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 Stock Acquisition Date or Section 13
Event, the Company shall not be required to issue fractions of shares of Common
Stock upon exercise of the Rights or to distribute certificates which evidence
fractional shares of Common Stock.  In lieu of fractional shares of Common
Stock, the Company may pay to the registered holders of Rights Certificates at
the time such Rights are exercised as herein provided an 

                                       25
<PAGE>
 
amount in cash equal to the same fraction of current market value of one 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 Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above).

          (e) The Rights Agent shall have no duty or obligation with respect to
this Section 14 and Section 24(d) unless and until it has received specific
instructions (and sufficient cash, if required) from the Company with respect to
its duties and obligations under such Sections.

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

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

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

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

          (c) subject to Sections 6 and 7(f), the Company and the Rights Agent
may deem and treat the Person in whose name the Rights Certificate (or, prior to
the Distribution 

                                       26
<PAGE>
 
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 Right Certificates or the associated Common Stock
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent, subject to
the last sentence of Section 7(e), shall be affected by any notice to the
contrary; and

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

      17. Rights Certificate Holder Not Deemed a Shareholder.  No holder, as
          --------------------------------------------------                
such, of any Rights Certificate shall be entitled to vote, receive dividends or
be deemed for any purpose the holder of the number of one one-hundredths 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
shareholder of the Company or any right to vote for the election of directors or
upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting shareholders (except as provided in Section 23(c)), or
to receive dividends or subscription rights, or otherwise, until the Rights
evidenced by such Rights Certificate shall have been exercised in accordance
with the provisions hereof.

      18. Concerning the Rights Agent.
          --------------------------- 

          (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
other disbursements incurred in the preparation, delivery, administration,
execution and any amendment 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, damage, judgment,
fine, penalty, claim, demand, settlement costs or expense incurred without gross
negligence, bad faith or willful misconduct on the part of the Rights Agent, as
determined by a court of competent jurisdiction, for any action taken, suffered
or omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including without limitation the costs and
expenses of defending against any claim of liability.

                                       27
<PAGE>
 
          (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 acceptance and administration of this Agreement in reliance upon any
Rights Certificate or certificate for shares of 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.

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

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

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

      20. Duties of Rights Agent.  The Rights Agent undertakes only the duties
          ----------------------                                              
and obligations expressly 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 written advice or opinion of such counsel
shall be full and 

                                       28
<PAGE>
 
complete authorization and protection to the Rights Agent for,
and the Rights Agent shall incur no liability for or in respect of,  any action
taken, suffered  or omitted by it in good faith and in accordance with such
written advice or opinion.

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

          (c) The Rights Agent shall be liable hereunder to the Company and any
other Person only for its own gross negligence, bad faith or willful misconduct,
each as determined by a court of competent jurisdiction.  Anything to the
contrary notwithstanding, in no event shall the Rights Agent be liable for
special, punitive, indirect, consequential or incidental loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Rights
Agent has been advised of the likelihood of such loss or damage.

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

          (e) The Rights Agent shall not have any liability or be under any
responsibility in respect of the validity of this Agreement or the execution and
delivery hereof (except the due execution hereof by the Rights Agent) or in
respect of the validity or execution of any Rights Certificate (except its
countersignature thereof); nor shall it be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any
Rights Certificate; nor shall it be responsible for any change in the
exercisability of the Rights (including the Rights becoming null and void
pursuant to Section 7(e) hereof) or any adjustment in the terms of the Rights
(including the manner, method or amount thereof) provided for in this Agreement
or the ascertaining of the existence of facts that would require any such change
or adjustment (except with respect to the exercise of Rights evidenced by Rights
Certificates after actual notice that such change or adjustment is required);
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 Preferred Stock
or Common Stock to be issued pursuant to this Agreement or any Right Certificate
or as to whether any shares of Preferred Stock or Common Stock will, when
issued, be validly authorized and issued, fully paid and nonassessable.

                                       29
<PAGE>
 
          (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 any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Secretary or the 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, omitted to be taken or suffered by
it in good faith in accordance with instructions of any such officer or for any
delay in acting while waiting for those instructions.  Any application by the
Agent for written instructions from the Company may, at the option of the Rights
Agent, set forth in writing any action proposed to be taken or omitted to be
taken by the Rights Agent under this Agreement and the date on or after which
such action shall be taken or such omission shall be effective.  The Rights
Agent shall not be liable for any action taken or suffered by, or omission of,
the Rights Agent in accordance with a proposal included in any such application
on or after the date specified in such application (which date shall not be less
than five Business Days after the date any such officer of the Company actually
receives such application, unless any such officer shall have consented in
writing to an earlier date) unless, prior to taking any such action (or the
effective date in the case of an omission), the Rights Agent shall have received
written instructions in response to such application specifying the action to be
taken, suffered or omitted.

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

          (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company or any other Person resulting from any
such act, default, neglect or misconduct, absent gross negligence, bad faith or
willful misconduct 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
its believes that repayment of such funds or adequate indemnification against
such risk or liability is not reasonably assured to it.

                                       30
<PAGE>
 
          (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.

      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 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 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 30 days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then the registered holder of
any Rights Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent.  Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be (a) a Person organized and
doing business under the laws of the United States or of any State of the United
States, in good standing, which is authorized under such laws to exercise stock
transfer powers and is subject to supervision or examination by federal or state
authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $50 million or (b) an affiliate or
subsidiary 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 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
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, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be.

      22. Issuance of New 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 

                                       31
<PAGE>
 
class of shares or other securities or property purchasable under the Rights
Certificates made in accordance with the provisions of this Agreement. In
addition, in connection with the issuance or sale of Common Stock of the Company
following the Distribution Date and prior to the Final Expiration Date, the
Company (a) shall, with respect to Common Stock of the Company so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement, or upon the exercise, conversion or exchange of securities issued
by the Company prior to the Distribution Date, and (b) may, in any other case,
if deemed necessary or appropriate by the Board of Directors, issue Rights
Certificates representing the appropriate number of Rights in connection with
such issuance or sale; provided, however, that (i) no such Rights Certificate
                       --------  -------             
shall be issued if, and to the extent that, the Company shall be advised by
counsel that such issuance would create a significant risk of material adverse
tax consequences to the Company or the person to whom such Rights Certificate
would be issued, and (ii) no such Rights Certificate shall be issued if, and to
the extent that, appropriate adjustment shall otherwise have been made in lieu
of the issuance thereof.

      23. Redemption.
          ---------- 

          (a) The Board of Directors of the Company may at its option, at any
time prior to the earliest of (i) the Close of Business on the tenth day
following a 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 Close of Business on the Final Expiration
Date, redeem all but not less than all the then outstanding Rights at a
redemption price of $.001 per Right, 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 as provided in Section 11(a)(ii) until such time as the
Company's right of redemption hereunder has expired.

          (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights (or at such later time as shall be
specified in the resolution taking such action), 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.  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 holders of the then outstanding Rights and the Rights Agent by mailing
such notice to all such holders at their last addresses as they appear upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the transfer agent for the shares of 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.  The
Company may, at its option, pay the Redemption Price in cash, shares of Common
Stock (based on the Current Per Share Market Price, as defined in Section 11(d),
of the Common Stock at the time of redemption) or any other form of
consideration deemed appropriate by the Board of Directors.

                                       32
<PAGE>
 
          (c) In case the Company shall propose (a) to pay any dividend payable
in stock of any class to the holders of its Preferred Stock or Common Stock or
to make any other distribution to the holders of its Preferred Stock or Common
Stock (other than a regular quarterly cash dividend), (b) to offer to the
holders of its Preferred Stock or Common Stock rights or warrants to subscribe
for or to purchase any additional shares of Preferred Stock or Common Stock or
shares of stock of any class or any other securities, (c) to effect any
reclassification of its Preferred Stock or Common Stock (other than a
reclassification involving only the subdivision of outstanding shares of
Preferred Stock or Common Stock), (d) to effect any consolidation, merger or
share exchange into or with any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(m)), (e) to effect any
sale or other transfer or to permit one or more of its Subsidiaries to effect
any sale or other transfer, in one or more related transactions, of 50 percent
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person (other than the Company and/or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(m)), or (f) 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 25, a
notice of such proposed action, which shall specify the record date for the
purposes of such stock dividend or distribution of rights or warrants, or the
date on which such reclassification, consolidation, merger, exchange, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the Preferred Stock or Common 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 (a) or (b) above at least 20 days prior to the
record date for determining holders of the Preferred Stock or Common Stock for
purposes of such action, and in the case of any such other action, at least 20
days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Preferred Stock or Common Stock
whichever shall be the earlier.

     In case a Stock Acquisition Date shall occur, the Company shall as soon as
practicable thereafter give to the Rights Agent and to each holder of a Rights
Certificate, in accordance with Section 25, 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).

      24. Exchange.
          -------- 

          (a) The Board of Directors of the Company may, at its option, at any
time and from time to time after a Stock Acquisition Date, exchange all or part
of the then outstanding and exercisable Rights (which shall not include Rights
that have become null and void pursuant to the provisions of Section 7(e)) for
shares of Common Stock or Common Stock Equivalents, or any combination thereof,
at an exchange ratio of one share of Common Stock, or such number of Common
Stock Equivalents or units representing fractions thereof as would be deemed to
have the same value as 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").

                                       33
<PAGE>
 
          (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 and/or
Common Stock Equivalents equal to the number of such Rights held by such holder
multiplied by the Exchange Ratio.  The Company shall promptly give public notice
of any such exchange (with prompt notice thereof to the Rights Agent); 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 the Rights Agent and to all of the holders of such
Rights at their last addresses as they appear upon the registry books of the
Rights Agent.  Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice.  Each such notice
of exchange will state the method by which the exchange of the shares of Common
Stock and/or Common Stock Equivalents for Rights will be effected and, in the
event of any partial exchange, the number of Rights which will be exchanged.
Any partial exchange shall be effected pro rata based on the number of Rights
(other than Rights which have become null and void pursuant to the provisions of
Section 7(e)) held by each holder of Rights.

          (c) In the event that the number of shares of Common Stock which are
authorized by the Company's Articles of Incorporation as amended but not
outstanding or reserved for issuance for purposes other than upon exercise of
the Rights are not sufficient to permit an exchange of Rights as contemplated in
accordance with this Section 24, the Company may, at its option, take all such
action as may be necessary to authorize additional shares of Common Stock for
issuance upon exchange of the Rights.

          (d) The Company shall not be required to issue fractions of shares of
Common Stock or to distribute certificates which evidence fractional shares of
Common Stock.  In lieu of such fractional shares of Common Stock, the company
shall pay to the registered holders of Rights 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 value of a whole share of Common Stock.  For
purposes of this Section 24, the value of a whole share of Common Stock shall be
the closing price (as determined pursuant to the second sentence of Section
11(d)(i) for the Trading Day immediately prior to the date of exchange pursuant
to this Section 24, and the value of any Common Stock Equivalent shall be deemed
to have the same value as the Common Stock on such date.

shall be deemed coincident with the interests of the holders of shares of Common
Stock.

      27. Successors.  All the covenants and provisions of this Agreement by or

notwithstanding anything in this Agreement to the contrary, if any such term,
provision, covenant or restriction is held by such court or authority to be
invalid, void or unenforceable and the Board of Directors of the Company
