                  RE: SHARES OF WATSON WYATT & COMPANY HOLDINGS

Dear Fellow Shareholder:

We are asking that you enter into this letter agreement in consideration for the
agreement of the several underwriters, for which Deutsche Bank Securities Inc.
intends to act as representative, to underwrite a proposed public offering
("IPO" or "offering") of Class A common stock of Watson Wyatt & Company
Holdings, our newly-created Delaware holding company, as described in the proxy
statement transmitted to you on May 24, 2000 and as contemplated by the
registration statement filed with the Securities and Exchange Commission on Form
S-3, as amended. By signing below, you hereby agree that you will not, directly
or indirectly, without our prior written consent, "transfer" Watson Wyatt &
Company Holdings shares during the following periods, the last of which will end
four years after the public offering date: o 25% of the aggregate Watson Wyatt &
Company Holdings shares which you own immediately following the IPO may be
transferred beginning one year after the public offering date;

     o    25% of the aggregate Watson Wyatt & Company Holdings shares which you
          own immediately following the IPO may be transferred beginning two
          years after the public offering date;

     o    25% of the aggregate Watson Wyatt & Company Holdings shares which you
          own immediately following the IPO may be transferred beginning three
          years after the public offering date; and

     o    25% of the aggregate Watson Wyatt & Company Holdings shares which you
          own immediately following the IPO may be transferred beginning four
          years after the public offering date.

As you know, at the time of the IPO your shares of Watson Wyatt & Company stock
will be converted into Class B-1 and Class B-2 shares of Watson Wyatt & Company
Holdings. The Class B shares are subject to restrictions contained in the
Certificate of Incorporation of Watson Wyatt & Company Holdings, as described in
the proxy statement which was provided to you in May 24, 2000. Under the
Certificate of Incorporation you may only sell such shares which have been duly
converted to Class A shares on the first and second anniversaries of the IPO,
respectively. Any sales of shares permitted by this letter agreement remain
subject to the requirements contained in the Certificate of Incorporation,
including those related to the conversion of Class B shares into Class A shares.

By signing below, you also authorize us during the foregoing periods to cause
the company's designated transfer agent to decline to transfer and to note stop
transfer restrictions on our transfer books and records with respect to any such
shares. In the case of any shares for which you are the beneficial but not the
record holder, you agree to cause the record holder to cause the company's
designated transfer agent to decline to transfer and to note stop transfer
restrictions on the books and records with respect to such shares.

The term "transfer" includes selling, offering or agreeing to sell, granting any
option for the sale of, pledging, making any short sale or maintaining any short
position, establishing or maintaining a "put equivalent position" (within the
meaning of

the rules under the Securities Exchange Act of 1934, as amended), entering into
any swap, derivative transaction or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of the stock
(whether any such transaction is to be settled by delivery of shares, other
securities, cash or other consideration) or otherwise disposing of, such stock
(or any securities convertible into, exercisable for or exchangeable for such
shares) or interest in the shares.

Despite the foregoing restrictions, if you are an individual, you may transfer
shares (or any securities convertible into, exercisable for, or exchangeable for
such shares) in accordance with the provisions of the Watson Wyatt & Company
Holdings Certificate of Incorporation governing "Permitted Transferees," or to
your immediate family, or to a trust the beneficiaries of which are exclusively
you and/or a member or members of your immediate family (for purposes of this
paragraph, "immediate family" shall mean spouse, lineal descendant, father,
mother, brother or sister of the transferor); PROVIDED in any such case it is a
condition to the transfer that (i) each transferee execute an agreement stating
that the transferee is receiving and holding the shares (or any securities
convertible into, exercisable for, or exchangeable for such shares) subject to
the provisions of this letter agreement, and that there will be no further
transfer of the shares (or any securities convertible into, exercisable for, or
exchangeable for such shares) except in accordance with this letter agreement
and (ii) each transferee certifies in writing to us that such transferee is in
compliance with the terms of this letter agreement as if such transferee had
been bound as of the original date of this letter agreement.

The restrictions contained in this letter agreement will terminate immediately
upon the involuntary termination of your employment, your retirement, your
death, or in the event of a transaction involving a sale of all or substantially
all of the assets or stock of Watson Wyatt & Company Holdings; PROVIDED HOWEVER,
that notwithstanding the occurrence of any of the events enumerated in this
paragraph, the restrictions contained in the Certificate of Incorporation,
including those related to the conversion of Class B shares into Class A shares,
shall remain applicable to all shares.

This letter agreement shall be governed by the laws of the state of New York.

You hereby represent and warrant that you have full power and authority to enter
into this letter agreement, and that, upon request, you will execute any
additional documents necessary in connection with its enforcement. Any of your
obligations under this letter agreement will be binding upon you successors and
assigns.

Very truly yours,

                                RIGHTS AGREEMENT

         Agreement, dated as of ____________, 2000 between Monolithic System
Technology, Inc., a Delaware corporation (the "Company"), and __________________
(the "Rights Agent").

         Pursuant to this Agreement, the Board of Directors of the Company has
authorized and declared a dividend of one preferred share purchase right (a
"Right") for each Common Share (as hereinafter defined) of the Company
outstanding on ____________, 2000 (the "Record Date"), each Right representing
the right to purchase one one-thousandth of a Preferred Share (as hereinafter
defined), upon the terms and subject to the conditions herein set forth, and has
further authorized and directed the issuance of one Right with respect to each
Common Share that shall become outstanding between the Record Date and the
earliest of the Distribution Date, the Redemption Date and the Final Expiration
Date (as such terms are hereinafter defined).

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

SECTION 1.        CERTAIN DEFINITIONS

         For purposes of this Agreement, the following terms have the meanings
indicated:

         (a) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates and Associates
(as such terms are hereinafter defined) of such Person, shall be the Beneficial
Owner (as such term is hereinafter defined) of 15% or in the case of (i) a
Grandfathered Stockholder other than a Second Tier Grandfathered Stockholder
25%, or (ii) a Second Tier Grandfathered Stockholder such percentage as is
beneficially owned by each Grandfathered Stockholder whose common shares the
Second Tiered Grandfathered Stockholder may be deemed to beneficially own plus
1%, or more of the Common Shares of the Company then outstanding, but shall not
include the Company, any Subsidiary (as such term is hereinafter defined) of the
Company, any employee benefit plan of the Company (including without limitation
the Plans) or of any Subsidiary of the Company, or of any entity holding Common
Shares for or pursuant to the terms of any such employee benefit plan.
Notwithstanding the foregoing, (1) no Person shall become an "Acquiring Person"
as the result of an acquisition of Common Shares by the Company which, by
reducing the number of shares outstanding, increases the proportionate number of
shares beneficially owned by such Person to 15% or more of the Common Shares of
the Company then outstanding; PROVIDED, HOWEVER, that if a Person shall become
the Beneficial Owner of 15% or more of the Common Shares of the Company then
outstanding by reason of share purchases by the Company and shall, after such
share purchases by the Company, become the Beneficial Owner of any additional
Common Shares of the Company, then such Person shall be deemed to be an
"Acquiring Person"; and (2) if the Board of Directors of the Company determines
in good faith that a Person who would otherwise be an "Acquiring Person," as
defined pursuant to the foregoing provisions of this paragraph, has become such
inadvertently, and such Person divests as promptly as practicable a sufficient
number of Common Shares so that such Person would no longer be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this paragraph, then
such

                                       1

<PAGE>

Person shall not be deemed to have become an "Acquiring Person" for any
purposes of this Agreement.

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

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

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

              (ii) which such Person or any of such Person's Affiliates or
     Associates has (A) the right to acquire (whether such right is exercisable
     immediately or only after the passage of time) pursuant to any agreement,
     arrangement or understanding (other than customary agreements with and
     between underwriters and selling group members with respect to a bona fide
     public offering of securities), or upon the exercise of conversion rights,
     exchange rights, rights (other than these Rights), warrants or options, or
     otherwise; PROVIDED, HOWEVER, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, securities tendered pursuant
     to a tender or exchange offer made pursuant to and in accordance with the
     applicable rules and regulations promulgated under the Exchange Act by or
     on behalf of such Person or any of such Person's Affiliates or Associates
     until such tendered securities are accepted for purchase or exchange; or
     (B) the right to vote pursuant to any agreement, arrangement or
     understanding; PROVIDED, HOWEVER, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, any security if the agreement,
     arrangement or understanding to vote such security (1) arises solely from a
     revocable proxy or consent given to such Person in response to a public
     proxy or consent solicitation made pursuant to, and in accordance with, the
     applicable rules and regulations promulgated under the Exchange Act and (2)
     is not also then reportable on Schedule 13D under the Exchange Act (or any
     comparable or successor report); or

              (iii) which are beneficially owned, directly or indirectly, by any
     other Person with which such Person or any of such Person's Affiliates or
     Associates has any agreement, arrangement or understanding (other than
     customary agreements with and between underwriters and selling group
     members with respect to a bona fide public offering of securities) for the
     purpose of acquiring, holding, voting (except to the extent contemplated by
     the proviso in Section l(c)(ii)(B)) or disposing of any securities of the
     Company; PROVIDED, HOWEVER, that in no case shall an officer or director of
     the Company be deemed the Beneficial Owner of securities held of record by
     the trustee of any employee benefit plan of the Company (including without
     limitation the Plans) or any Subsidiary of the Company for the benefit of
     any employee of the Company or any Subsidiary of the Company, other than
     the officer or director, by reason of any influence that such officer or
     director may have over the voting of the securities held in the plan.

              Notwithstanding anything in this definition of Beneficial
     Ownership to the contrary, the phrase "then outstanding," when used with
     reference to a Person's Beneficial Ownership of securities of the Company,
     shall mean the number of such securities then issued and outstanding
     together with the number of such securities not then actually issued and
     outstanding which such Person would be deemed to own beneficially
     hereunder.

                                       2

as any Person becomes an Acquiring Person) after the date of the commencement by
any Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
holding Common Shares for or pursuant to the terms of any such plan) of, or of
the first public announcement

                                       4
<PAGE>

of the intention of any Person (other than any of the persons referred to in
the preceding sentence) or of any Subsidiary of the Company or any entity
holding Common Shares for or pursuant to the terms of any such plan) to
commence, a tender or exchange offer the consummation of which would result
in any Person becoming the Beneficial Owner of Common Shares aggregating 15%
or in the case of (i) a Grandfathered Stockholder other than a Second Tier
Grandfathered Stockholder 25%, or (ii) a Second Tier Grandfathered
Stockholder such percentage as is beneficially owned by each Grandfathered
Stockholder whose common shares the Second Tiered Grandfathered Stockholder
may be deemed to beneficially own plus 1%, or more of the then outstanding
Common Shares (irrespective of whether any Common Shares are actually
purchased pursuant to such offer) (including any such date which is after the
date of this Agreement and prior to the issuance of the Rights), (the
earliest of such dates being herein referred to as the "Distribution Date"),
(x) the Rights will be evidenced (subject to the provisions of Section 3(b)
hereof) by the certificates for Common Shares registered in the names of the
holders thereof (which certificates shall also be deemed to be Right
Certificates) and not by separate Right Certificates, and (y) the right to
receive Right Certificates will be transferable only in connection with the
transfer of Common Shares. As soon as practicable after the Distribution
Date, the Company will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights
Agent will, if requested, send) by first-class, insured, postage-prepaid
mail, to each record holder of Common Shares as of the close of business on
the Distribution Date, at the address of such holder shown on the records of
the Company, a Right Certificate, in substantially the form of Exhibit B
hereto (a "Right Certificate"), evidencing one Right for each Common Share so
held. As of the Distribution Date, the Rights will be evidenced solely by
such Right Certificates.

         (b) On the Record Date, or as soon as practicable thereafter, the
Company will send a copy of a Summary of Rights by first-class, postage-prepaid
mail, to each record holder of Common Shares as of the close of business on the
Record Date, at the address of such holder shown on the records of the Company.
With respect to certificates for Common Shares outstanding as of the Record
Date, until the Distribution Date, the Rights will be evidenced by such
certificates registered in the names of the holders thereof regardless of
whether a copy of the Summary of Rights is attached thereto. Until the
Distribution Date (or the earlier of the Redemption Date or the Final Expiration
Date), the surrender for transfer of any certificate for Common Shares
outstanding on the Record Date, with or without a copy of the Summary of Rights
attached thereto, shall also constitute the transfer of the Rights associated
with the Common Shares represented thereby.

         (c) Certificates for Common Shares which become outstanding (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this paragraph (c)) after the Record Date but prior to the earliest of the
Distribution Date, the Redemption Date or Close of Business on 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 as set forth in a Rights Agreement between
              Monolithic System Technology, Inc. and ________________ dated as
              of ____________, 2000 (the "Rights Agreement"), the terms of which
              are hereby incorporated herein by reference and a copy of which is
              on file at the principal executive offices of Monolithic System
              Technology, Inc. Under certain circumstances, as set forth in the
              Rights Agreement, such Rights will be evidenced by separate
              certificates and will no longer be evidenced by this certificate.
              Monolithic System Technology, Inc. will mail to the holder of this
              certificate a copy of the Rights

                                       5
<PAGE>

              Agreement without charge after receipt of a written request
              therefor. Under certain circumstances, as set forth in the
              Rights Agreement, Rights issued to any Person who becomes an
              Acquiring Person (as defined in the Rights Agreement) may
              become null and void.

         With respect to such certificates containing the foregoing legend,
until the Distribution Date, the Rights associated with the Common Shares
represented by such certificates shall be evidenced by such certificates alone,
and the surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Company purchases or acquires any Common Shares after the
Record Date but prior to the Distribution Date, the Company shall not be
entitled to exercise any Rights associated with such Common Shares which are no
longer outstanding.

SECTION 4.        FORM OF RIGHT CERTIFICATES

         The Right Certificates (and the forms of election to purchase Preferred
Shares and 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 and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange or other organization on which the
Rights may from time to time be listed or quoted, or to conform to usage.
Subject to the other provisions of this Agreement, the Right Certificates shall
entitle the holders thereof to purchase such number of one one-thousandths of a
Preferred Share as shall be set forth therein at the price per one
one-thousandths of a Preferred Share set forth therein (the "Purchase Price"),
but the number of such one one-hundredths of a Preferred Share and the Purchase
Price shall be subject to adjustment as provided herein.

SECTION 5.        COUNTERSIGNATURE AND REGISTRATION

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

         Following the Distribution Date, the Rights Agent will keep or cause to
be kept, at its principal office, books for registration and transfer of the
Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of the Right Certificates, the

                                       6

<PAGE>

number of Rights evidenced on its face by each of the Right Certificates and
the date of each of the Right Certificates.

SECTION 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHT CERTIFICATES;
           MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES

         Subject to the provisions of Section 14 hereof, at any time after the
Close of Business on the Distribution Date, and at or prior to the Close of
Business on the earlier of the Redemption Date or the Final Expiration Date, any
Right Certificate or Right Certificates (other than Right Certificates
representing Rights that have become void pursuant to Section 11(a)(ii) hereof
or that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Right Certificate or Right
Certificates, entitling the registered holder to purchase a like number of one
one-thousandths of a Preferred Share as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any Right Certificate
or Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

         Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Right
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them and, 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 Right Certificate if mutilated, the Company will make and deliver a new
Right Certificate of like tenor to the Rights Agent for delivery to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

SECTION 7. EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS

         (a) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (other than a holder whose Rights have become void
pursuant to Section 11(a)(ii) hereof or have been exchanged, pursuant to Section
24 hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Right Certificate, with the form of election to purchase on the
reverse side thereof duly executed, to the Rights Agent at the principal office
of the Rights Agent, together with payment of the Purchase Price for each one
one-thousandth of a Preferred Share as to which the Rights are exercised, at or
prior to the earliest of (i) the Close of Business on the Final Expiration Date,
(ii) the Redemption Date, or (iii) the time at which such Rights are exchanged
as provided in Section 24 hereof.

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

         (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the number of

                                       7

<PAGE>

one one-thousandths of a Preferred Share to be purchased and an amount equal
to any applicable transfer tax required to be paid by the holder of such
Right Certificate in accordance with Section 9 hereof by cash, certified
check, cashier's check or money order payable to the order of the Company,
the Rights Agent shall thereupon promptly (i) (A) requisition from any
transfer agent of the Preferred Shares certificates for the number of one
one-thousandths of a Preferred Share to be purchased and the Company hereby
irrevocably authorizes its transfer agent to comply with all such requests,
or (B) requisition from the depository agent depository receipts representing
such number of one one-thousandths of a Preferred Share as are to be
purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent with the depository
agent) and the Company hereby directs the depository agent to comply with
such request, (ii) when appropriate, requisition from the Company the amount
of cash to be paid in lieu of issuance of fractional shares in accordance
with Section 14 hereof, (iii) after receipt of such certificates or
depository receipts, cause the same to be delivered to or upon the order of
the registered holder of such Right Certificate, registered in such name or
names as may be designated by such holder and (iv) when appropriate, after
receipt, deliver such cash to or upon the order of the registered holder of
such Right Certificate.

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

SECTION 8. CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES

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

SECTION 9. AVAILABILITY OF PREFERRED SHARES

         (a) The Company covenants and agrees that it will cause to be reserved
and kept available out of its authorized and unissued Preferred Shares or any
Preferred Shares held in its treasury the number of Preferred Shares that will
be sufficient to permit the exercise in full of all outstanding Rights in
accordance with Section 7.

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

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

                                       8

<PAGE>

or delivery of the Right Certificates or of any Preferred Shares upon the
exercise of Rights. The Company shall not, however, be required to pay any
transfer tax which may be payable in respect of any transfer or delivery of
Right Certificates to a person other than, or the issuance or delivery of
certificates or depository receipts for the Preferred Shares in a name other
than that of, the registered holder of the Right Certificate evidencing
Rights surrendered for exercise or to issue or to deliver any certificates or
depository receipts for Preferred Shares upon the exercise of any Rights
until any such tax shall have been paid (any such tax being payable by the
holder of such Right Certificate at the time of surrender) or until it has
been established to the Company's reasonable satisfaction that no such tax is
due.

SECTION 10. PREFERRED SHARES RECORD DATE

         Each person in whose name any certificate for Preferred Shares is
issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of the Preferred Shares represented thereby on, and
such certificate shall be dated, the date upon which the Right Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer taxes) was made; PROVIDED, HOWEVER, that if the
date of such surrender and payment is a date upon which the Preferred Shares
transfer books of the Company are closed, such person shall be deemed to have
become the record holder of such shares on, and such certificate shall be dated,
the next succeeding Business Day on which the Preferred Shares transfer books of
the Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Right Certificate shall not be entitled to any rights of a holder of
Preferred Shares for which the Rights shall be exercisable, including, without
limitation, the right to vote, to receive dividends or other distributions or to
exercise any preemptive rights, and shall not be entitled to receive any notice
of any proceedings of the Company, except as provided herein.

SECTION 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR NUMBER OF RIGHTS

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

         (a) (i) In the event the Company shall at any time after the date of
     this Agreement (A) declare a dividend on the Preferred Shares payable in
     Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C)
     combine the outstanding Preferred Shares into a smaller number of Preferred
     Shares or (D) issue any shares of its capital stock in a reclassification
     of the Preferred Shares (including any such reclassification in connection
     with a consolidation or merger in which the Company is the continuing or
     surviving corporation), except as otherwise provided in this Section 11(a),
     the Purchase Price in effect at the time of the record date for such
     dividend or of the effective date of such subdivision, combination or
     reclassification, and the number and kind of shares of capital stock
     issuable on such date, 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 Shares transfer books of the Company were open, he would have
     owned upon such exercise and been entitled to receive by virtue of such
     dividend, subdivision, combination or reclassification; PROVIDED, HOWEVER,
     that in no event shall the consideration to be paid upon the exercise of
     one Right be less than the aggregate par value of the shares of capital
     stock of the Company issuable upon exercise of one Right.

                                       9

<PAGE>

              (ii) Subject to the following paragraph of this subparagraph (ii)
     and Section 24 of this Agreement, in the event any Person shall become an
     Acquiring Person (other than through an acquisition described in
     subparagraph (iii) of this paragraph (a)) each holder (other than an
     Acquiring Person or any direct or indirect transferee of an Acquiring
     Person) of a Right shall thereafter have a right to receive, upon exercise
     thereof at a price equal to the then current Purchase Price multiplied by
     the number of one one-thousandths of a Preferred Share for which a Right is
     then exercisable, in accordance with the terms of this Agreement, such
     number of Common Shares (or, in the discretion of the Board of Directors,
     one one-thousandths of a Preferred Share) of the Company (such number of
     shares being referred to herein as the "Adjustment Shares") as shall equal
     the result obtained by (x) multiplying the then current Purchase Price by
     the number of one one-thousandths of a Preferred Share for which a Right is
     then exercisable and dividing that product by (y) 50% of the then current
     per share market price of the Company's Common Shares (determined pursuant
     to Section 11(d) hereof) on the date such Person became an Acquiring
     Person.

              Upon and after the occurrence of a Trigger Event, any Rights that
     are or were acquired or are or were beneficially owned by such Acquiring
     Person (or any Associate or Affiliate of such Acquiring Person) on or after
     the earlier of (x) the date of such event and (y) the Distribution Date
     shall be void and any holder of such Rights (including any subsequent
     transferee) shall thereafter have no right to exercise such Rights under
     any provision of this Agreement. No Right Certificate shall be issued
     pursuant to Section 3 that represents Rights beneficially owned by an
     Acquiring Person whose Rights would be void pursuant to the preceding
     sentence or any Associate or Affiliate thereof; no Right Certificate shall
     be issued at any time upon the transfer of any Rights to an Acquiring
     Person whose Rights would be void pursuant to the preceding sentence or any
     Associate or Affiliate thereof or to any nominee of such Acquiring Person,
     Associate or Affiliate; and any Right Certificate delivered to the Rights
     Agent for transfer to an Acquiring Person whose Rights would be void
     pursuant to the preceding sentence shall be canceled.

              (iii) The right to buy Common Shares of the Company pursuant to
     subparagraph (ii) of this paragraph (a) shall not arise as a result of any
     Person becoming an Acquiring Person through a purchase of Common Shares
     pursuant to a tender offer made in the manner prescribed by Section 14(d)
     of the Exchange Act and the rules and regulations promulgated thereunder;
     PROVIDED, HOWEVER, that such tender offer shall provide for the acquisition
     of all of the outstanding Common Shares held by any Person other than such
     Person and its Affiliates or Associates at a price and on terms determined
     by at least a majority of the members of the Board of Directors who are not
     officers of the Company and who are not representatives, nominees,
     Affiliates or Associates of an Acquiring Person, after receiving advice
     from one or more investment or financial advisers, to be (A) fair to
     stockholders (taking into account all factors which such members of the
     Board deem relevant including, without limitation, prices which could
     reasonably be achieved if the Company or its assets were sold on an orderly
     basis designed to realize maximum value) and (B) otherwise in the best
     interests of the Company and its stockholders, employees, customers and
     communities in which the Company does business.

              (iv) In the event that there shall not be sufficient Common Shares
     authorized by the Company's Certificate of Incorporation but unissued to
     permit the exercise in full of the Rights in accordance with the foregoing
     subparagraph (ii), the Company shall: (A) determine the excess of (1) the
     value of the Adjustment Shares issuable upon the exercise of a Right (the
     "Current Value"), over (2) the Purchase Price (such excess being
     hereinafter referred to as the "Spread"),

                                       10

<PAGE>

     and (B) with respect to each Right, make adequate provision to
     substitute for such unavailable Adjustment Shares any one or more of the
     following having an aggregate value determined by the Board of Directors
     to be equal to Current Value: (1) cash, (2) a reduction in the Purchase
     Price, (3) Common Shares other equity securities of the Company,
     including without limitation, Preferred Shares, (4) debt securities of
     the Company, (5) other assets; PROVIDED, HOWEVER, if, within 30 days
     following the date of the Trigger Event, the Company shall have not made
     adequate provision to deliver value pursuant to clause (B) above, the
     Company shall be obligated to deliver, upon the surrender for exercise
     of a Right and without requiring payment of the Purchase Price, Common
     Shares (to the extent such shares are 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 Common Shares 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 following the date of the occurrence of the
     earliest of the Trigger Events, in order that the Company may seek
     stockholder approval for the authorization of such additional shares
     (such period, as it may be extended, hereinafter referred to as the
     "Substitution Period"). To the extent that the Company determines that
     action need be taken pursuant to the first and/or second sentences of
     this Section 11(a)(iv), the Company (x) shall provide, subject to
     Section 11(a)(ii) hereof, that such action shall apply uniformly to all
     outstanding Rights, and (y) may suspend the exercisability of the Rights
     until the expiration of the Substitution Period in order to seek any
     authorization of additional shares and/or to decide the appropriate form
     of distribution to be made pursuant to such first sentence and to
     determine the value thereof. In the event of any such suspension, the
     Company shall issue a public announcement stating that the
     exercisability of the Rights has been temporarily suspended, as well as
     a public announcement at such time as the suspension is no longer in
     effect. For purposes of this Section 11(a)(iv), the value of the Common
     Shares shall be the current per share market price (as determined
     pursuant to Section 11(d) hereof) per Common Share on the date of the
     occurrence of the earliest of the Trigger Events.

         (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current per
share market price of the Preferred Shares (as defined in Section 11(d)) on such
record date, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of
Preferred Shares outstanding on such record date plus the number of Preferred
Shares which the aggregate offering price of the total number of Preferred
Shares and/or equivalent preferred shares so to be offered (and/or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at such current market price and the denominator of which shall be the
number of Preferred Shares outstanding on such record date plus the number of
additional Preferred Shares and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors

                                       11

<PAGE>

of the Company, whose determination shall be described in a statement
filed with the Rights Agent. Preferred Shares 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 record
date is fixed; and in the event that such rights, options or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

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

         (d) (i) For the purpose of any computation hereunder, the "current per
     share market price" of any security (a "Security" for the purpose of this
     Section 11(d)(i)) on any date shall be deemed to be the average of the
     daily closing prices per share of such Security for the 30 consecutive
     Trading Days (as such term is hereinafter defined) immediately prior to
     such date; PROVIDED, HOWEVER, that in the event that the current per share
     market price of the Security is determined during a period following the
     announcement by the issuer of such Security of (A) a dividend or
     distribution on such Security payable in shares of such Security or
     securities convertible into such shares, or (B) any subdivision,
     combination or reclassification of such Security and prior to the
     expiration of 30 Trading Days after the ex-dividend date for such dividend
     or distribution, or the record date for such subdivision, combination or
     reclassification, then, and in each such case, the current per share market
     price shall be appropriately adjusted to reflect the current market price
     per share equivalent of such Security. The closing price for each day shall
     be the last sale price or, in case no such sale takes place on such day,
     the average of the closing bid and asked prices regular way, in either case
     as reported in the principal consolidated transaction reporting system with
     respect to securities listed or admitted to trading on the New York Stock
     Exchange or, if the Security is not listed or admitted to trading on the
     New York Stock Exchange, as reported in the principal consolidated
     transaction reporting system with respect to securities listed on the
     principal national securities exchange on which the Security is listed or
     admitted to trading or, if the Security is not listed or admitted to
     trading on any national securities exchange, the last reported trade, as
     reported by the Nasdaq National Market ("Nasdaq") or such other system then
     in use, or, if on any such date the Security 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 Security selected by
     the Board of Directors of the Company. The term "Trading Day" shall

                                       12

<PAGE>

     mean a day on which the principal national securities exchange on which
     the Security is listed or admitted to trading is open for the
     transaction of business or, if the Security is not listed or admitted to
     trading on any national securities exchange, a Business Day.

              (ii)For the purpose of any computation hereunder, the "current per
     share market price" of the Preferred Shares shall be determined in
     accordance with the method set forth in Section 11(d)(i). If the Preferred
     Shares are not publicly traded, the "current per share market price" of the
     Preferred Shares shall be conclusively deemed to be the current per share
     market price of the Common Shares as determined pursuant to Section
     11(d)(i) (appropriately adjusted to reflect any stock split, stock dividend
     or similar transaction occurring after the date hereof), multiplied by one
     thousand. If neither the Common Shares nor the Preferred Shares are
     publicly held or so listed or traded, "current per share market price"
     shall mean the fair value per share as determined in good faith by the
     Board of Directors of the Company, whose determination shall be described
     in a statement filed with the Rights Agent.

         (e) No adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the Purchase
Price; PROVIDED, HOWEVER, that any adjustments which by reason of this Section
11(e) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Section 11
shall be made to the nearest cent or to the nearest one ten-millionth of a
Preferred Share or one one-thousandth of any other share or security, 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)
hereof, the holder of any Right thereafter exercised shall become entitled to
receive any shares of capital stock of the Company other than Preferred Shares,
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 Shares
contained in Section 11(a) through (c), inclusive, and the provisions of
Sections 7, 9, 10 and 13 with respect to the Preferred Shares shall apply on
like terms to any such other shares.

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

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

                                       13

<PAGE>

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

         (j) Irrespective of any adjustment or change in the Purchase Price or
the number of one one-thousandths of a Preferred Share issuable upon the
exercise of the Rights, the Right Certificates previously and thereafter issued
may continue to express the Purchase Price and the number of one one-thousandths
of a Preferred Share that were expressed in the initial Right Certificates
issued hereunder.

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

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

         (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly

                                       14

<PAGE>

required by this Section 11, as and to the extent that it in its sole
discretion shall determine to be advisable in order that any (i)
consolidation or subdivision of the Preferred Shares, (ii) issuance wholly
for cash of any Preferred Shares at less than the current market price, (iii)
issuance wholly for cash of Preferred Shares or securities which by their
terms are convertible into or exchangeable for Preferred Shares, (iv)
dividends on Preferred Shares payable in Preferred Shares or (v) issuance of
rights, options or warrants referred to hereinabove in Section 11(b),
hereafter made by the Company to holders of its Preferred Shares shall not be
taxable to such stockholders.

         (n) In the event that at any time after the date of this Agreement and
prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in any such case (A) the
number of one one-thousandths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-thousandths of a Preferred Share so purchasable immediately prior to
such event by a fraction, the numerator of which is the number of Common Shares
outstanding immediately before such event and the denominator of which is the
number of Common Shares outstanding immediately after such event, and (B) each
Common Share outstanding immediately after such event shall have issued with
respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments
provided for in this Section 11(p) shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

SECTION 12. CERTIFICATE OF ADJUSTMENT

         Whenever an adjustment is made as provided in Sections 11 and 13
hereof, the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with Section
25 hereof. The Rights Agent shall be fully protected in relying on any such
certificate and on any adjustment therein contained and shall not be deemed to
have knowledge of such adjustment unless and until it shall have received such
certificate.

SECTION 13. CONSOLIDATED, MERGER OR SALE OR TRANSFER OF ASSETS OR EARNING POWER

         (a) If, following the Shares Acquisition Date, directly or indirectly,
(i) the Company shall consolidate with, or merge with and into, any Interested
Stockholder or, if in any merger or consolidation all holders of Common Shares
are not treated alike, any other Person (in each case regardless of whether the
Company is the surviving or disappearing corporation), (ii) an Interested
Stockholder shall acquire all or a majority of the Common Shares pursuant to a
statutory plan of exchange, or (iii) the Company shall sell or otherwise
transfer (or one or more of its Subsidiaries shall sell or otherwise transfer),
in one or more transactions, assets or earning power aggregating 50% or more of
the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to one or more Interested Stockholders or, if all holders of Common
Shares are not treated alike in such transaction, any other Person other than to
the Company or one or more of its wholly-owned Subsidiaries, then, and in each
such case, proper provision shall be made so that (A) each holder of a Right
(except those held by an Acquiring Person or as otherwise provided herein) shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to the then current Purchase Price

                                       15

<PAGE>

multiplied by the number of one one-thousandths of a Preferred Share for
which a Right is then exercisable, in accordance with the terms of this
Agreement and in lieu of Preferred Shares, such number of Common Shares of
the Principal Party (as hereinafter defined), not subject to any liens,
encumbrances, rights of first refusal or other adverse claims, as shall equal
the result obtained by (x) multiplying the then current Purchase Price by the
number of one one-thousandths of a Preferred Share for which a Right is then
exercisable and dividing that product by (y) 50% of the then current per
share market price of the Common Shares (determined pursuant to Section 11(d)
hereof) of such Principal Party on the date of consummation of such
consolidation, merger, sale or transfer; (B) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such consolidation,
merger, sale or transfer, all the obligations and duties of the Company
pursuant to this Agreement; (C) the term "Company" shall thereafter be deemed
to refer to such Principal Party, it being specifically intended that the
provisions of Section 11 shall apply only to such Principal Party after the
first occurrence of an event described in this Section 13(a); (D) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of its Common Shares in accordance with
Section 9 hereof) in connection with such consummation as may be necessary to
assure that the provisions hereof shall thereafter be applicable, as nearly
as reasonably may be, in relation to the Common Shares thereafter deliverable
upon the exercise of the Rights.

         (b) "Principal Party" shall mean:

              (i) in the case of any transaction described in clause (i), (ii)
     or (iii) of Section 13(a), (A) the Person that is the issuer of any
     securities into which Common Shares of the Company are converted in such
     merger, consolidation or for which they are exchanged in such statutory
     plan of exchange, or, if there is more than one such issuer, the issuer of
     Common Shares that has the highest aggregate current market price
     (determined in accordance with Section 11(d)) and (B) if no securities are
     so issued, the Person that is the other party to such merger, consolidation
     or statutory plan of exchange, or, if there is more than one such Person,
     the Person the Common Shares of which has the highest aggregate current
     market price (determined in accordance with 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 largest 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 Shares of which has the highest
     aggregate current market price (determined in accordance with Section
     11(d));

provided, however, that in any such case, (A) if the Common Shares of such
Person are not at such time and have not been continuously over the preceding
twelve-month period registered under Section 12 of the Exchange Act ("Registered
Common Shares"), or such Person is not a corporation, and such Person is a
direct or indirect Subsidiary of another Person that has Registered Common
Shares outstanding, "Principal Party" shall refer to such other Person; (B) if
the Common Shares of such Person are not Registered Common Shares or such Person
is not a corporation, and such Person is a direct or indirect Subsidiary of
another Person but is not a direct or indirect Subsidiary of another Person
which has Registered Common Shares outstanding, "Principal Party" shall refer to
the ultimate parent entity of such first-mentioned Person; (C) if the Common
Shares of such Person are not Registered Common Shares or such Person is not a
corporation, and such Person is directly or indirectly controlled by more than
one Person, and one or more of such other Persons has Registered

                                       16

<PAGE>

Common Shares outstanding, "Principal Party" shall refer to whichever of such
other Persons is the issuer of the Registered Common Shares having the
highest aggregate current market price (determined in accordance with Section
11(d)); and (D) if the Common Shares of such Person are not Registered Common
Shares or such Person is not a corporation, and such Person is directly or
indirectly controlled by more than one Person, and none of such other Persons
have Registered Common Shares outstanding, "Principal Party" shall refer to
whichever ultimate parent entity is the corporation having the greatest
stockholders' equity or, if no such ultimate parent entity is a corporation,
shall refer to whichever ultimate parent entity is the entity having the
greatest net assets.

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

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

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

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

         (f) Notwithstanding anything in this Agreement to the contrary, this
Section 13 shall not be applicable to a transaction described in Section
13(a)(i), (ii) or (iii) if: (i) such transaction is consummated with a Person or
Persons who acquired Common Shares pursuant to a tender offer described in
Section 11(a)(iii) (or with a wholly-owned Subsidiary of any such Person or
Persons), (ii) the price per Common Share offered in such transaction is not
less than the price per Common Share paid to all holders of Common Shares whose
shares were purchased pursuant to such tender or

                                       17

<PAGE>

exchange offer, and (iii) the form of consideration being offered to the
remaining holders of Common Shares pursuant to such transaction is the same
as the form of consideration paid pursuant to such tender offer. Upon
consummation of any such transaction contemplated by this Section 13(e), all
Rights shall expire.

SECTION 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES

         (a) The Company shall not be required to issue fractions of Rights or
to distribute Right Certificates which evidence fractional Rights. In lieu of
such fractional Rights, there shall be paid to the registered holders of the
Right Certificates with regard to which such fractional Rights would otherwise
be issuable, an amount in cash equal to the same fraction of the 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, regular or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, way in either case as reported in
the principal consolidated transaction reporting system with respect to
securities listed or admitted to trading on the New York Stock Exchange or, if
the Rights are not listed or admitted to trading on the New York Stock Exchange,
as reported in the principal consolidated transaction reporting system with
respect to securities listed on the principal national securities exchange on
which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
reported trade in the over-the-counter market, as reported by Nasdaq or such
other system then in use or, if on any such date the Rights are not quoted by
any such organization, the average of the closing bid and asked prices as
furnished by a professional market maker making a market in the Rights selected
by the Board of Directors of the Company. If on any such date no such market
maker is making a market in the Rights, the fair value of the Rights on such
date as determined in good faith by the Board of Directors of the Company shall
be used.

         (b) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-thousandth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-thousandth of a Preferred Share). Fractions of
Preferred Shares in integral multiples of one one-thousandth of a Preferred
Share may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it; PROVIDED, that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Shares
represented by such depositary receipts. In lieu of fractional Preferred Shares
that are not integral multiples of one one-thousandth of a Preferred Share, the
Company shall pay to the registered holders of Right Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share. For the purposes of
this Section 14(b), the current market value of a Preferred Share shall be the
closing price of a Preferred Share (as determined pursuant to the second
sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to
the date of such exercise.

         (c) 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).

                                       18

SECTION 15. RIGHTS OF ACTION

         All rights of action in respect of this Agreement, excepting the rights
of action given to the Rights Agent under Section 18 hereof, are vested in the
respective registered holders of the Right Certificates (and, prior to the
Distribution Date, the registered holders of the Common Shares); and any
registered holder of any Right Certificate (or, prior to the Distribution Date,
of the Common Shares), without the consent of the holder of any other Right
Certificate (or, prior to the Distribution Date, of the Common Shares), may, on
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 Right
Certificate in the manner provided in such Right Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of
any Person subject to, this Agreement.

SECTION 16. AGREEMENT OF RIGHT HOLDERS

         Every holder of a Right, by accepting the same, consents and agrees
with the Company and with every other holder of a Right that:

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

         (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

         (c) the Company and the Rights Agent may deem and treat the person in
whose name the Right Certificate (or, prior to the Distribution Date, the
associated Common Shares 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 Shares
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary.

SECTION 17. RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER

         No holder, as such, of any Right Certificate, shall be entitled to
vote, receive dividends or be deemed for any purpose the holder of the Preferred
Shares or any other securities of the Company which may at any time be issuable
on the exercise of the Rights represented thereby, nor shall anything contained
herein or in any Right Certificate be construed to confer upon the holder of any
Right Certificate, as such, any of the rights of a stockholder of the Company or
any right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

                                       19

<PAGE>

SECTION 18. CONCERNING THE RIGHTS AGENT

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

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

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

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

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

SECTION 20. DUTIES OF RIGHTS AGENT

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

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

         (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Executive Vice President, or the
Secretary of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Agreement in reliance upon such
certificate.

         (c) The Rights Agent shall be liable hereunder to the Company and any
other Person only for its own negligence, bad faith or willful misconduct.
Anything in this Agreement to the contrary notwithstanding, in no event shall
the Rights Agent be liable for special, indirect or consequential loss or damage
of any kind whatsoever (including, but not limited to, lost profits), even if
the Rights Agent has been advised of the likelihood of such loss or damage and
regardless of the form of action.

         (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 Right
Certificates (except its countersignature thereof) or be required to verify the
same, but all such statements and recitals are and shall be deemed to have been
made by the Company only.

         (e) The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Right Certificate; nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 11(a)(ii) hereof) or any adjustment in
the terms of the Rights (including the manner, method or amount thereof)
provided for in Section 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right 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 Preferred Shares to be issued pursuant to
this Agreement or any Right Certificate or as to whether any Preferred Shares
will, when issued, be validly authorized and issued, fully paid and
nonassessable.

         (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and

                                       21

<PAGE>

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 Executive 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 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.

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

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

SECTION 21. CHANGE OF RIGHTS AGENT

         The Rights Agent or any successor Rights Agent may resign and be
discharged from its duties under this Agreement upon 30 days' notice in writing
mailed to the Company and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right 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 Shares or Preferred Shares by registered or certified mail,
and to the holders of the Right Certificates by first-class mail. If the Rights
Agent shall resign or be removed or shall otherwise become incapable of acting,
the Company shall appoint a successor to the Rights Agent. 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
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Company), the registered holder of any Right Certificate may
apply to any court of competent jurisdiction for the appointment of a new Rights
Agent. Any successor Rights Agent, whether appointed by the Company or by such a
court, shall be a corporation (or an affiliate of a corporation) organized and
doing business under the laws of the United States or any state of the United
States so long as such corporation is authorized to do business as a banking
institution, is authorized under such laws to exercise corporate trust or stock
transfer powers, is in good standing, and is subject to supervision or
examination by federal or state authority, and has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $100
million. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the

                                       22

<PAGE>

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 with the
predecessor Rights Agent and each transfer agent of the Common Shares or
Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the
legality or validity of the resignation or removal of the Rights Agent or the
appointment of the successor Rights Agent, as the case may be.

SECTION 22. ISSUANCE OF NEW RIGHT CERTIFICATES

         Notwithstanding any of the provisions of this Agreement or of the
Rights to the contrary, the Company may, at its option, issue new Right
Certificates evidencing Rights in such form as may be approved by its Board of
Directors to reflect any adjustment or change in the Purchase Price and the
number or kind or class of shares or other securities or property purchasable
under the Right Certificates made in accordance with the provisions of this
Agreement.

SECTION 23. REDEMPTION

         (a) The Board of Directors of the Company may, at its option, at any
time prior to such time as any Person becomes an Acquiring Person, redeem all
but not less than all the then outstanding Rights at a redemption price of $0.01
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"); PROVIDED, HOWEVER, that if,
following the occurrence of a Shares Acquisition Date and following the
expiration of the right of redemption hereunder but prior to any event described
in clause (B) of Section 11(a)(ii) or clauses (i), (ii), (iii) or (iv) of
Section 13(a) hereof, (i) a Person who is an Acquiring Person shall have
transferred or otherwise disposed of a number of shares of Common Shares in one
transaction or series of transactions, not directly or indirectly involving the
Company or any of its Subsidiaries, which did not result in the occurrence of an
event described in clause (B) of Section 11(a)(ii) or clauses (i), (ii) or (iii)
of Section 13(a) hereof such that such Person is thereafter a Beneficial Owner
of less than 10% of the outstanding Common Shares, and (ii) there are no other
Persons, immediately following the occurrence of the event described in clause
(i), who are Acquiring Persons, then the right of redemption shall be reinstated
and thereafter be subject to the provisions of this Section 23. The redemption
of the Rights by the Board of Directors may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish. The Company may, in its discretion, round up the
redemption price to be paid to any holder of Rights to the nearest whole cent.

         (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, and without any further action and without any notice, the right to
exercise the Rights will terminate and the only right thereafter of the holders
of Rights shall be to receive the Redemption Price. The Company shall promptly
give public notice of any such redemption; PROVIDED, HOWEVER, that the failure
to give, or any defect in, any such notice shall not affect the validity of such
redemption. Within 10 days after such action of the Board of Directors ordering
the redemption of the Rights, the Company shall mail a notice of redemption to
all the holders of the then outstanding Rights at their last addresses as they
appear upon the registry books of the Rights Agent or, prior to the Distribution
Date, on the registry books of the transfer agent for the Common Shares. Any
notice which is mailed in the manner herein

                                       23

<PAGE>

provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of redemption will state the method by which the
payment of the Redemption Price will be made.

SECTION 24. EXCHANGE

         (a) The Board of Directors of the Company may, at its option, at any
time after any Person becomes an Acquiring Person, exchange all or part of the
then outstanding and exercisable Rights (which shall not include Rights that
have become void pursuant to the provisions of Section 11(a)(ii) hereof) for
Common Shares at an exchange ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such exchange ratio being hereinafter referred
to as the "Exchange Ratio"). Notwithstanding the foregoing, the Board of
Directors shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company (including without limitation the Employee Plans) or
of any such Subsidiary, or of any entity holding Common Shares for or pursuant
to the terms of any such plan), together with all Affiliates and Associates of
such Person, becomes the Beneficial Owner of 50% or more of the Common Shares
then outstanding.

         (b) Immediately upon the action of the Board of Directors 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 Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice of any such exchange; PROVIDED,
HOWEVER, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange. The Company promptly shall mail a notice
of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the Common Shares for Rights will be effected
and, in the event of any partial exchange, the number of Rights which will be
exchanged. Any partial exchange shall be effected pro rata based on the number
of Rights (other than Rights which have become void pursuant to the provisions
of Section 11(a)(ii) hereof) held by each holder of Rights.

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

         (d) In the event that there shall not be sufficient Common Shares or
Preferred Shares issued but not outstanding or authorized but unissued to permit
any exchange of Rights as contemplated in accordance with this Section 24, the
Company shall use its best efforts to cause all such action to be taken as may
be necessary to authorize additional Common Shares or Preferred Shares for
issuance upon exchange of the Rights.

         (e) The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such fractional Common Shares,

                                       24

<PAGE>

the Company shall pay to the registered holders of the Right Certificates
with regard to which such fractional Common Shares would otherwise be
issuable an amount in cash equal to the same fraction of the current market
value of a whole Common Share. For the purposes of this paragraph (e), the
current market value of a whole Common Share shall be the closing price of a
Common Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

SECTION 25. NOTICE OF CERTAIN EVENTS

         (a) In case the Company shall propose (i) to pay any dividend payable
in stock of any class to the holders of its Preferred Shares or to make any
other distribution to the holders of its Preferred Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of its Preferred Shares
rights or warrants to subscribe for or to purchase any additional Preferred
Shares or shares of stock of any class or any other securities, rights or
options, (iii) to effect any reclassification of its Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, or distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the Common Shares and/or Preferred
Shares, if any such date is to be fixed, and such notice shall be so given in
the case of any action covered by clause (i) or (ii) above at least 10 days
prior to the record date for determining holders of the Preferred Shares for
purposes of such action, and in the case of any such other action, at least 10
days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Common Shares and/or Preferred
Shares, whichever shall be the earlier.

         (b) In case any of the events set forth in Section 11(a)(ii) hereof
shall occur, the Company shall as soon as practicable thereafter give to each
holder of a Right Certificate, in accordance with Section 26 hereof, a notice of
the occurrence of such event, which notice shall describe such event and the
consequences of such event to holders of Rights under Section 11(a)(ii) hereof.
