ITEM 1.  DESCRIPTION OF SECURITIES TO BE REGISTERED.

         On April 22, 1998, the Board of Directors of Wang Laboratories, Inc.
(the "Company") declared a dividend distribution of one Right for each
outstanding share of Common Stock to stockholders of record at the close of
business on May 1, 1998 (the "Record Date"). Each Right entitles the registered
holder to purchase from the Company one one-thousandth of a share of Series C
Junior Participating Preferred Stock, par value $0.01 per share (the "Preferred
Stock"), at a Purchase Price of $120, subject to adjustment. The description and
terms of the Rights are set forth in a Rights Agreement (the "Rights Agreement")
between the Company and American Stock Transfer and Trust Company, as Rights
Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) ten (10) business days (or
such later date as the Board shall determine) following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") has acquired, or obtained the right to acquire, beneficial ownership of
15% or more of the outstanding shares of Common Stock or, with respect to Ing.
C. Olivetti & C. S.p.A., has acquired, or obtained the right to acquire,
beneficial ownership of more than 19.9% of the outstanding shares of Common
Stock (the "Stock Acquisition Date"), other than as a result of repurchases of
stock by the Company, or (ii) ten (10) business days (or such later date as the
Board shall determine) following the commencement of a tender offer or exchange
offer that would result in a person or group becoming an Acquiring Person. Until
the Distribution Date, (i) the Rights will be evidenced by the Common Stock
certificates and will be transferred with and only with such Common Stock
certificates, (ii) new Common Stock certificates issued after the Record Date
will contain a notation incorporating the Rights Agreement by reference and
(iii) the surrender for transfer of any certificates for Common Stock
outstanding will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate. Pursuant to the Rights Agreement,
the Company reserves the right to require prior to the occurrence of a
Triggering Event (as defined below) that, upon any exercise




<PAGE>   3

of Rights, a number of Rights be exercised so that only whole shares of
Preferred Stock will be issued.

         The Rights are not exercisable until the Distribution Date and will
expire at the close of business on April 22, 2008, unless earlier redeemed or
exchanged by the Company as described below.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights. 

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

         For example, at an exercise price of $120 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following an event
set forth in the preceding paragraph would entitle its holder to purchase $240
worth of Common Stock (or other consideration, as noted above) for $120.
Assuming that the Common Stock had a per share value of $30 at such time, the
holder of each valid Right would be entitled to purchase 8 shares of Common
Stock for $120.




<PAGE>   4

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

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

         At any time until ten (10) business days (or such later date as the
Board shall determine) following the Stock Acquisition Date, the Company may
redeem the Rights in whole, but not in part, at a price of $.01 per Right (pay
able in cash, Common Stock or other consideration deemed appropriate by the
Board). Immediately upon the action of the Board ordering redemption of the
Rights, the Rights will terminate and the only right of the holders of Rights
will be to receive the $.01 redemption price. The foregoing notwithstanding, the
Rights generally may not be redeemed for one hundred eighty (180) days following
a change in a majority of the Board as a result of a proxy contest.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company,




<PAGE>   5

stockholders may, depending upon the circumstances, recognize taxable income in
the event that the Rights become exercisable for Common Stock (or other
consideration) of the Company or for common stock of the acquiring company as
set forth above.

         Any of the provisions of the Rights Agreement may be amended by the
Board prior to the Distribution Date. After the Distribution Date, the
provisions of the Rights Agreement may be amended by the Board in order to cure
any ambiguity, to make changes which do not adversely affect the interests of
holders of Rights, or to shorten or lengthen any time period under the Rights
Agreement.

         The Rights Agreement, dated as of April 22, 1998, between the Company
and American Stock Transfer and Trust Company, as Rights Agent, specifying the
terms of the Rights and including the form of the Certificate of Designation,
Preferences and Rights setting forth the terms of the Preferred Stock as an
exhibit thereto, and the press release announcing the declaration of the Rights
are attached hereto as exhibits and are incorporated herein by reference. The
foregoing description of the Rights is qualified in its entirety by reference to
such exhibits.

                                RIGHTS AGREEMENT

         RIGHTS AGREEMENT, dated as of April 22, 1998 (this "Agreement"),
between Wang Laboratories, Inc., a Delaware corporation (the "Company"), and
American Stock Transfer and Trust Company, a New York banking corporation (the
"Rights Agent").

                               W I T N E S S E T H


         WHEREAS, on April 22, 1998 (the "Rights Dividend Declaration Date"),
the Board of Directors of the Company (the "Board") authorized and declared a
dividend distribution of one Right (as hereinafter defined) for each share of
Common Stock (as hereinafter defined) outstanding at the close of business on
May 1, 1998 (the "Record Date"), and has authorized the issuance of one Right
(as such number may hereinafter be adjusted pursuant to the provisions of
Section 11(p) hereof) for each share of Common Stock of the Company issued
between the Record Date (whether originally issued or delivered from the
Company's treasury) and the Distribution Date (as hereinafter defined) each
Right initially representing the right to purchase one one-thousandth of a share
of Preferred Stock (as hereinafter defined), upon the terms



<PAGE>   5

and subject to the conditions hereinafter set forth (the "Rights");

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

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

              (a) "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the shares of Common Stock then outstanding,
but shall not include (i) the Company, (ii) any Subsidiary of the Company, (iii)
any employee benefit plan of the Company, or of any Subsidiary of the Company,
or any Person or entity organized, appointed or established by the Company for
or pursuant to the terms of any such plan, or (iv) any such Person who becomes
the Beneficial Owner of fifteen percent (15%) or more of the shares of Common
Stock then outstanding as a result of a reduction in the number of shares of
Common Stock outstanding due to the repurchase of shares of Common Stock by the
Company unless and until such Person, after becoming aware that such Person has



                                       2

<PAGE>   6

become the Beneficial Owner of fifteen percent (15%) or more of the then
outstanding shares of Common Stock, acquires beneficial ownership of additional
shares of Common Stock representing one percent (1%) or more of the shares of
Common Stock then outstanding, (v) any such Person who has reported or is
required to report such ownership (but less than 20%) on Schedule 13G under the
Exchange Act (or any comparable or successor report) or on Schedule 13D under
the Exchange Act (or any comparable or successor report) which Schedule 13D does
not state any intention to or reserve the right to control or influence the
management or policies of the Company or engage in any of the actions specified
in Item 4 of such schedule (other than the disposition of the Common Stock) and,
within 10 Business Days of being requested by the Company to advise it regarding
the same, certifies to the Company that such Person acquired shares of Common
Stock in excess of 14.9% inadvertently or without knowledge of the terms of the
Rights and who, together with all Affiliates and Associates, thereafter does not
acquire additional shares of Common Stock while the Beneficial Owner of 15% or
more of the shares of Common Stock then outstanding; PROVIDED, HOWEVER, that if
the Person requested to so certify fails to do so within 10 Business Days,



                                       3

<PAGE>   7

then such Person shall become an Acquiring Person immediately after such
10-Business-Day period, or (vi) an Exempted Person.

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

              (c) "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Exchange Act.

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

                  (i) which such Person or any of such Person's Affiliates or
         Associates, directly or indirectly, owns or has the right to acquire
         (whether such right is exercisable immediately or only after the
         passage of time) pursuant to any agreement, arrangement or
         understanding (whether or not in writing) or upon the exercise of
         conversion rights, exchange rights, rights, warrants or options, or
         otherwise; PROVIDED, HOWEVER, that a Person shall not be deemed the
         "Beneficial Owner" of, or to "beneficially own," (A) securities
         tendered



                                       4

<PAGE>   8

         pursuant to a tender or exchange offer made by such Person or any of
         such Person's Affiliates or Associates until such tendered securities
         are accepted for purchase or exchange, (B) securities issuable upon
         exercise of Rights at any time prior to the occurrence of a Triggering
         Event (as hereinafter defined), or (C) securities issuable upon
         exercise of Rights from and after the occurrence of a Triggering Event
         which Rights were acquired by such Person or any of such Person's
         Affiliates or Associates prior to the Distribution Date (as hereinafter
         defined) or pursuant to Section 3(a) or Section 22 hereof (the
         "Original Rights") or pursuant to Section 11(i) hereof in connection
         with an adjustment made with respect to any Original Rights;

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



                                       5

<PAGE>   9

         ment, arrangement or understanding, whether or not in writing; 
         PROVIDED, HOWEVER, that a Person shall not be deemed the "Beneficial 
         Owner" of, or to "beneficially own," any security under this 
         subparagraph (ii) as a result of an agreement, arrangement or 
         understanding to vote such security if such agreement, arrangement or 
         understanding: (A) arises solely from a revocable proxy or consent 
         given in response to a public proxy or consent solicitation made 
         pursuant to, and in accordance with, the applicable provisions of the 
         General Rules and Regulations under the Exchange Act, and (B) is not 
         reportable by such Person 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 (or any Affiliate or Associate thereof) with which such
         Person (or any of such Person's Affiliates or Associates) has any
         agreement, arrangement or understanding (whether or not in writing),
         for the purpose of acquiring, holding, voting (except pursuant to a
         revocable



                                       6

<PAGE>   10

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

PROVIDED, HOWEVER, that nothing in this paragraph (d) shall cause a Person
engaged in business as an underwriter of securities to be the "Beneficial Owner"
of, or to "beneficially own," any securities acquired through such Person's

Date) after the date that a tender or exchange offer by any Person (other than
the Company, any Subsidiary of the Company, any employee benefit plan of the
Company or of any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such

                                       14

Stock of the Company as of the close of business on the Distribution Date, at
the address of such holder shown on the records of the Company, one or more
right certificates, in substantially the form of Exhibit B hereto (the "Rights
Certificates"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in the
number of Rights per share of Common Stock of the Company has been made pursuant
to Section 11(i) or Section 11(p) hereof, at the time of distribution of the
Rights Certificates, the Company shall make the necessary and appropriate
rounding adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights. As of and after the Distribution Date,
the Rights will be evidenced solely by such Rights Certificates.

              (b) The Company will make available, as promptly as practicable
following the Record Date, a copy of a Summary of Rights, in substantially the
form attached hereto as Exhibit C (the "Summary of Rights") to any holder of
Rights who may so request from time to time prior to the Expiration Date. With
respect to certificates for the Common Stock of the Company outstanding as



                                       15
<PAGE>   19

of the Record Date, until earlier of the Distribution Date or the Expiration
Date, the Rights will be evidenced by such certificates for the Common Stock of
the Company and the registered holders of the Common Stock of the Company shall
also be the registered holders of the associated Rights. Until the earlier of
the Distribution Date or the Expiration Date, the transfer of any certificates
representing shares of Common Stock of the Company in respect of which Rights
have been issued shall also constitute the transfer of the Rights associated
with such shares of Common Stock of the Company.

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

                  This certificate also evidences and entitles the holder hereof
         to certain Rights as set forth in the Rights Agreement between Wang
         Laboratories, Inc. (the "Company") and the Rights Agent thereunder (the
         "Rights Agreement"), the terms of which are hereby incorporated herein
         by reference and a copy of which is on file at the principal offices of
         the Company. Under certain circumstances, as set



                                       16
<PAGE>   20

         forth in the Rights Agreement, such Rights will be evidenced by
         separate certificates and will no longer be evidenced by this
         certificate. The Company will mail to the holder of this certificate a
         copy of the Rights Agreement, as in effect on the date of mailing,
         without charge, promptly after receipt of a written request therefor.
         Under certain circumstances set forth in the Rights Agreement, Rights
         beneficially owned (as such term is defined in the Rights Agreement) by
         any Person who is, was or becomes an Acquiring Person or any Affiliate
         or Associate thereof (as such terms are defined in the Rights
         Agreement), whether currently held by or on behalf of such Person or by
         any subsequent holder, may become null and void.

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

         Section 4. FORM OF RIGHTS CERTIFICATES.

              (a) The Rights Certificates (and the forms of election to purchase
and of assignment to be printed on the reverse thereof) shall each be
substantially in the form set forth in Exhibit B hereto and may



                                       17
<PAGE>   21

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

              (b) Any Rights Certificate issued pursuant to Section 3(a),
Section 11(i) or Section 22 hereof that represents Rights beneficially owned by:
(i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person,
(ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate)
who becomes a transferee after the Acquiring Person becomes such, or (iii) a
transferee of an Acquiring 



                                       18
<PAGE>   22

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

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

         Section 5.  COUNTERSIGNATURE AND REGISTRATION.

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



                                       20
<PAGE>   24

Certificate, although at the date of the execution of this Rights Agreement any
such person was not such an officer.

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

         Section 6. TRANSFER, SPLIT-UP, COMBINATION AND EXCHANGE OF RIGHTS
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

              (a) Subject to the provisions of Section 4(b), Section 7(e) and
Section 14 hereof, at any time after the close of business on the Distribution
Date, and at or prior to the close of business on the Expiration Date, any
Rights Certificate or Certificates (other than Rights Certificates representing
Rights that may have been exchanged pursuant to Section 24 hereof) may be
transferred, split up, combined or exchanged for another 



                                       21
<PAGE>   25

Rights Certificate or Certificates, entitling the registered holder to purchase
a like number of one one-thousandths of a share of Preferred Stock (or,
following a Triggering Event, Common Stock of the Company, other securities,
cash or other assets, as the case may be) as the Rights Certificate or
Certificates surrendered then entitles such holder (or former holder in the case
of a transfer) to purchase. Any registered holder desiring to transfer, split
up, combine or exchange any Rights Certificate or Certificates shall make such
request in writing delivered to the Rights Agent, and shall surrender the Rights
Certificate or Certificates to be transferred, split up, combined or exchanged
at the principal office or offices of the Rights Agent designated for such
purpose. Neither the Rights Agent nor the Company shall be obligated to take any
action whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent 



                                       22
<PAGE>   26

shall, subject to Section 4(b), Section 7(e), Section 14 hereof and Section 24
hereof, countersign and deliver to the Person entitled thereto a Rights
Certificate or Rights Certificates, as the case may be, as so requested. The
Company may require payment of a sum sufficient to cover any tax or governmental
charge that may be imposed in connection with any transfer, split up,
combination or exchange of Rights Certificates.

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

surrendered Rights are then exercisable, at or prior to the earliest of (i) 5:00
P.M., New York City time, on April 22, 2008, (the "Final Expiration Date"), (ii)
the time at which the Rights are redeemed or exchanged as provided in Section 23

<PAGE>   28

              (b) The Purchase Price for each one one-thousandth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $120, and
shall be subject to adjustment from time to time as provided in Section 11 and
Section 13(a) hereof and shall be payable in accordance with paragraph (c)
below.

              (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per one one-thousandth of a share of Preferred Stock (or other securities,
cash or other assets, as the case may be) to be purchased as set forth below and
an amount equal to any applicable transfer tax, the Rights Agent shall, subject
to Section 7(f) and Section 20(k) hereof, thereupon promptly (i) (A) requisition
from any transfer agent of the shares of Preferred Stock (or make available, if
the Rights Agent is the transfer agent for such shares) certificates for the
total number of one one-thousandths of a share of Preferred Stock to be
purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company shall have elected to
deposit the total number of shares of Pre-



                                       25
<PAGE>   29

ferred Stock issuable upon exercise of the Rights hereunder with a depositary
agent, requisition from the depositary agent depositary receipts representing
such number of one one-thousandths of a share of Preferred Stock as are to be
purchased (in which case certificates for the shares of Preferred Stock
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company will direct the depositary agent to comply
with such request, (ii) requisition from the Company the amount of cash, if any,
to be paid in lieu of fractional shares in accordance with Section 14 hereof,
(iii) after receipt of such certificates or depositary receipts, cause the same
to be delivered to or upon the order of the registered holder of such Rights
Certificate, registered in such name or names as may be designated by such
holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon
the order of the registered holder of such Rights Certificate. The payment of
the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)
hereof) shall be made in cash or by certified bank check or bank draft payable
to the order of the Company. In the event that the Company is obligated to issue
other securities (including Common Stock) of the Company, pay cash or dis-



                                       26
<PAGE>   30

tribute other property pursuant to Section 11(a) hereof, the Company will make
all arrangements necessary so that such other securities, cash or other property
are available for distribution by the Rights Agent, if and when appropriate. The
Company reserves the right to require prior to the occurrence of a Triggering
Event that, upon any exercise of Rights, a number of Rights be exercised so that
only whole shares of Preferred Stock would be issued.

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

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



                                       27

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



                                       28
<PAGE>   32

Acquiring Person or its Affiliates, Associates or transferees hereunder.

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

         Section 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All
Rights Certificates surrendered for the purpose of exercise, transfer, split-up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this 



                                       29
<PAGE>   33

Agreement. The Company shall deliver to the Rights Agent for cancellation and
retirement, and the Rights Agent shall so cancel and retire, any other Rights
Certificate purchased or acquired by the Company otherwise than upon the
exercise thereof. The Rights Agent shall deliver all cancelled Rights
Certificates to the Company, or shall, at the written request of the Company,
destroy such cancelled Rights Certificates, and in such case shall deliver a
certificate of destruction thereof to the Company.

         Section 9. RESERVATION AND AVAILABILITY OF CAPITAL STOCK.

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



                                       30
<PAGE>   34

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

              (c) The Company shall use its best efforts to (i) file, as soon as
practicable following the earliest date after the first occurrence of a
Triggering Event on which the consideration to be delivered by the Company upon
exercise of the Rights has been determined in accordance with this Agreement, a
registration statement under the Act, with respect to the securities purchasable
upon exercise of the Rights on an appropriate form, (ii) cause such registration
statement to become effective as soon as practicable after such filing, and
(iii) cause such registration statement to remain effective (with a prospectus
at all times meeting the requirements of the Act) until the earlier of (A) the
date as of which the Rights are no longer exercisable for such securities, and
(B) the Expiration Date. The Company



                                       31
<PAGE>   35

will also take such action as may be appropriate under, or to ensure compliance
with, the securities or "blue sky" laws of the various states and other
jurisdictions in connection with the exercisability of the Rights. The Company
may temporarily suspend, for a period of time not to exceed ninety (90) days
after the date set forth in clause (i) of the first sentence of this Section
9(c), the exercisability of the Rights in order to prepare and file such
registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension has been rescinded. In addition, if
the Company shall determine that a registration statement is required in other
circumstances following the Distribution Date, the Company may similarly
temporarily suspend the exercisability of the Rights until such time as a
registration statement has been declared effective. Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any jurisdiction if the requisite qualification in such jurisdiction shall
not have been obtained, the exercise thereof shall not be permitted under
applicable law, or a 



                                       32
<PAGE>   36

registration statement shall not have been declared effective.

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

              (e) The Company further covenants and agrees that, except as set
forth in Section 6(a) hereof or in this Section 9(e), it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Rights Certificates and of
any certificates for a number of one one-thousandths of a share of Preferred
Stock (or Common Stock or other securities, as the case may be) upon the
exercise of Rights. The Company shall not, however, be required to pay any
transfer tax which may be payable in respect of any transfer or delivery of
Rights Certificates to a Person other than, or the



                                       33
<PAGE>   37

issuance or delivery of a number of one one-thousandths of a share of Preferred
Stock (or Common Stock or other securities, as the case may be) in respect of a
name other than that of the registered holder of the Rights Certificates
evidencing Rights surrendered for exercise or to issue or deliver any
certificates for a number of one one-thousandths of a share of Preferred Stock
(or Common Stock or other securities, as the case may be) in a name other than
that of the registered holder upon the exercise of any Rights until such tax
shall have been paid (any such tax being payable by the holder of such Rights
Certificate at the time of surrender) or until it has been established to the
Company's satisfaction that no such tax is due.

         Section 10. RECORD DATE FOR SECURITIES ISSUED UPON EXERCISE. Each 
person in whose name any certificate for a number of one one-thousandths of a 
share of Preferred Stock (or Common Stock or other securities, as the case may 
be) is issued upon the exercise of Rights shall for all purposes be deemed to 
have become the holder of record of such fractional shares of Preferred Stock 
(or Common Stock or other securities, as the case may be) represented thereby 
on, and such certificate shall be dated, the date upon which the Rights 
Certificate evi-



                                       34
<PAGE>   38

dencing such Rights was duly surrendered and payment of the Purchase Price (and
all applicable transfer taxes) was made; PROVIDED, HOWEVER, that if the date of
such surrender and payment is a date upon which the Preferred Stock (or Common
Stock or other securities, as the case may be) transfer books of the Company are
closed, such Person shall be deemed to have become the record holder of such
shares (fractional or otherwise) on, and such certificate shall be dated, the
next succeeding Business Day on which the Preferred Stock (or Common Stock or
other securities, as the case may be) transfer books of the Company are open.
Prior to the exercise of the Rights evidenced thereby, the holder of a Rights
Certificate shall not be entitled to any rights of a stockholder of the Company
with respect to shares for which the Rights shall be exercisable, including,
without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

         Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR
NUMBER OF RIGHTS. The Purchase Price, the number and kind of shares, or
fractions thereof, purchasable upon exercise of each Right



                                       35
<PAGE>   39

and the number of Rights outstanding are subject to adjustment from time to time
as provided in this Section 11.

              (a)(i) In the event the Company shall at any time after the date
of this Agreement (A) declare a dividend on the Preferred Stock payable in
shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C)
combine the outstanding Preferred Stock into a smaller number of shares or (D)
issue any shares of its capital stock in a reclassification of the Preferred
Stock (including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), except
as otherwise provided in this Section 11(a) and Section 7(e) hereof, the
Purchase Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification, and the
number and kind of shares of Preferred Stock or capital stock, as the case may
be, issuable on such date, shall be proportionately adjusted so that the holder
of any Right exer-



                                       36
<PAGE>   40

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

                 (ii) In the event any Person shall, at any time after the
Rights Dividend Declaration Date, become an Acquiring Person, unless the event
causing such Person to become an Acquiring Person is a transaction set forth



                                       37
<PAGE>   41

in Section 13(a) hereof, or is an acquisition of shares of Common Stock pursuant
to a tender offer or an exchange offer for all outstanding shares of Common
Stock at a price and on terms determined by at least a majority of the members
of the Board of Directors who are not officers of the Company and who are not
representatives, nominees, Affiliates or Associates of an Acquiring Person,
after receiving advice from one or more investment banking firms, to be (x) at a
price which is fair to stockholders and not inadequate (taking into account all
factors which such members of the Board deem relevant, including, without
limitation, prices which could reasonably be achieved if the Company or its
assets were sold on an orderly basis designed to realize maximum value) and (y)
otherwise in the best interests of the Company and its stockholders (a
"Qualified Offer") then, promptly following the occurrence of such event, proper
provision shall be made so that each holder of a Right (except as provided below
and in Section 7(e) hereof) shall thereafter have the right to receive, upon



                                       38
<PAGE>   42

exercise thereof at the then current Purchase Price in accordance with the terms
of this Agreement, in lieu of a number of one one-thousandths of a share of
Preferred Stock, such number of shares of Common Stock of the Company as shall
equal the result obtained by (x) multiplying the then current Purchase Price by
the then number of one one-thousandths of a share of Preferred Stock for which a
Right was exercisable immediately prior to the first occurrence of a Section
11(a)(ii) Event, and (y) dividing that product (which, following such first
occurrence, shall thereafter be referred to as the "Purchase Price" for each
Right and for all purposes of this Agreement) by 50% of the Current Market Price
per share of Common Stock on the date of such first occurrence (such number of
shares being referred to as the "Adjustment Shares").

                 (iii) In the event that the number of shares of Common Stock of
the Company which are authorized by the Company's certificate of incorporation,
but not outstanding or reserved for issuance for purposes other than 



                                       39
<PAGE>   43

upon exercise of the Rights, is not sufficient to permit the exercise in full of
the Rights in accordance with the foregoing subparagraph (ii) of this Section
11(a), the Company shall (A) determine the value of the Adjustment Shares
issuable upon the exercise of a Right (the "Current Value"), and (B) with
respect to each Right (subject to Section 7(e) hereof), make adequate provision
to substitute for the Adjustment Shares, upon the exercise of a Right and
payment of the applicable Purchase Price, (1) cash, (2) a reduction in the
Purchase Price, (3) Common Stock or other equity securities of the Company
(including, without limitation, shares of preferred stock, such as the Preferred
Stock, which the Board has deemed to have essentially the same value or economic
rights as shares of Common Stock (such shares of preferred stock being referred
to as "Common Stock Equivalents")), (4) debt securities of the Company, (5)
other assets, or (6) any combination of the foregoing, having an aggregate value
equal to the Current Value, where such aggregate value has been determined by
the 



                                       40
<PAGE>   44

Board based upon the advice of a nationally recognized investment banking firm
selected by the Board; PROVIDED, HOWEVER, that if the Company shall not have
made adequate provision to deliver value pursuant to clause (B) above within
thirty (30) days following the later of (x) the first occurrence of a Section
11(a)(ii) Event and (y) the date on which the Company's right of redemption
pursuant to Section 23(a) hereof expires (the later of (x) and (y) being
referred to herein as the "Section 11(a)(ii) Trigger Date"), then the Company
shall be obligated to deliver, upon the surrender for exercise of a Right and
without requiring payment of the Purchase Price, shares of Common Stock (to the
extent available) and then, if necessary, cash, which shares or cash have an
aggregate value equal to the Spread. For purposes of the preceding sentence, the
term "Spread" shall mean the excess of (i) the Current Value over (ii) the
Purchase Price. If the Board determines in good faith that it is likely that
sufficient additional shares of Common Stock could be authorized for issuance
upon exercise



                                       41
<PAGE>   45

in full of the Rights, the thirty (30) day period set forth above may be
extended to the extent necessary, but not more than ninety (90) days after the
Section 11(a)(ii) Trigger Date, in order that the Company may seek shareholder
approval for the authorization of such additional shares (such thirty (30) day
period, as it may be extended, is herein called the "Substitution Period"). To
the extent that action is to be taken pursuant to the first or third sentences
of this Section 11(a)(iii), the Company (1) shall provide, subject to Section
7(e) hereof, that such action shall apply uniformly to all outstanding Rights,
and (2) may suspend the exercisability of the Rights until the expiration of the
Substitution Period in order to seek such shareholder approval for such
authorization of additional shares 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
tempo-



                                       42
<PAGE>   46

rarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect. For purposes of this Section 11(a)(iii), the
value of each Adjustment Share shall be the Current Market Price per share of
the Common Stock of the Company on the Section 11(a)(ii) Trigger Date and the
per share or per unit value of any Common Stock Equivalent shall be deemed to
equal the Current Market Price per share of the Common Stock of the Company on
such date.

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



                                       43
<PAGE>   47

Price per share of Preferred Stock on such record date, the Purchase Price to be
in effect after such record date shall be determined by multiplying the Purchase
Price in effect immediately prior to such record date by a fraction, the
numerator of which shall be the number of shares of Preferred Stock outstanding
on such record date, plus the number of shares of Preferred Stock which the
aggregate offering price of the total number of shares of Preferred Stock or
Equivalent Preferred Stock so to be offered (or the aggregate initial conversion
price of the convertible securities so to be offered) would purchase at such
Current Market Price, and the denominator of which shall be the number of shares
of Preferred Stock outstanding on such record date, plus the number of
additional shares of Preferred Stock or Equivalent Preferred Stock to be offered
for subscription or purchase (or into which the convertible securities so to be
offered are initially convertible). In case such subscription price may be paid
by delivery of consideration, part or all of which may be in a form other than
cash, the value of such consideration shall be as determined in good faith by
the Board, whose determination shall be described in a statement filed with the
Rights Agent and shall be conclusive for all purposes. Shares of Pre-



                                       44
<PAGE>   48

ferred Stock owned by or held for the account of the Company shall not be deemed
outstanding for the purpose of any such computation. Such adjustment shall be
made successively whenever such a record date is fixed, and in the event that
such rights or warrants are not so issued, the Purchase Price shall be adjusted
to be the Purchase Price which would then be in effect if such record date had
not been fixed.

              (c) In case the Company shall fix a record date for a distribution
to all holders of Preferred Stock (including any such distribution made in
connection with a consolidation or merger in which the Company is the continuing
corporation) of evidences of indebtedness, cash (other than a regular quarterly
cash dividend out of the earnings or retained earnings of the Company), assets
(other than a dividend payable in Preferred Stock, but including any dividend
payable in stock other than Preferred Stock) or evidences of indebtedness, or of
subscription rights or warrants (excluding those referred to in Section 11(b)
hereof), the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the Current Market
Price per share 



                                       45
<PAGE>   49

of Preferred Stock on such record date, less the fair market value (as
determined in good faith by the Board, whose determination shall be described in
a statement filed with the Rights Agent and shall be conclusive for all
purposes) of the portion of the cash, assets or evidences of indebtedness so to
be distributed or of such subscription rights or warrants applicable to a share
of Preferred Stock, and the denominator of which shall be such Current Market
Price per share of Preferred Stock. Such adjustments shall be made successively
whenever such a record date is fixed, and in the event that such distribution is
not so made, the Purchase Price shall be adjusted to be the Purchase Price which
would have been in effect if such record date had not been fixed.

              (d)(i For the purpose of any computation hereunder, other than
computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily closing prices per share of such Common Stock for the thirty (30)
consecutive Trading Days immediately prior to such date, and for purposes of
computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily 



                                       46
<PAGE>   50

closing prices per share of such Common Stock for the ten (10) consecutive
Trading Days immediately following such date; PROVIDED, HOWEVER, that in the
event that the Current Market Price per share of the Common Stock is determined
during a period following the announcement by the issuer of such Common Stock of
(A) a dividend or distribution on such Common Stock payable in shares of such
Common Stock or securities convertible into shares of such Common Stock (other
than the Rights), or (B) any subdivision, combination or reclassification of
such Common Stock, and the ex-dividend date for such dividend or distribution,
or the record date for such subdivision, combination or reclassification shall
not have occurred prior to the commencement of the requisite thirty (30) Trading
Day or ten (10) Trading Day period, as set forth above, then, and in each such
case, the Current Market Price shall be properly adjusted to take into account
ex-dividend trading. The closing price for each day shall be the last sale
price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if



                                       47
<PAGE>   51

the shares of Common Stock are not listed or admitted to trading on the New York
Stock Exchange, as reported in the principal consolidated transaction reporting
system or as quoted by the Nasdaq National Market with respect to securities
listed or admitted to trading on another national securities exchange or quoted
by the Nasdaq National Market, respectively, or, if the shares of Common Stock
are not listed or admitted to trading on any national securities exchange or
quoted by the Nasdaq National Market, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") or such other system then in use, or, if on any such
date the shares of Common Stock are not quoted by any such organization, the
average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Common Stock selected by the Board. If on
any such date the Common Stock is not publicly held or not so listed, admitted
to trading or quoted, and no market maker is making a market in the Common
Stock, the fair value of such shares on such date as determined in good faith by
the Board shall be used, whose determination shall be described in a



                                       48
<PAGE>   52

statement filed with the Rights Agent and shall be conclusive for all purposes.
The term "Trading Day" shall mean a day on which the principal national
securities exchange on which the shares of Common Stock are listed or admitted
to trading is open for the transaction of business or, if the shares of Common
Stock are not listed or admitted to trading on any national securities exchange,
a Business Day.

              (ii) For the purpose of any computation hereunder, the Current
Market Price per share of Preferred Stock shall be determined in the same manner
as set forth above for the Common Stock in clause (i) of this Section 11(d)
(other than the penultimate sentence thereof). If the Current Market Price per
share of Preferred Stock cannot be determined in the manner provided above or if
the Preferred Stock is not publicly held or listed or admitted to trading or
quoted in a manner described in clause (i) of this Section 11(d), the Current
Market Price per share of Preferred Stock shall be conclusively deemed to be an
amount equal to 1,000 (as such number may be appropriately adjusted for such
events as stock splits, stock dividends and recapitalizations with respect to
the Common Stock occurring after the date of this Agreement) multiplied by the
Current Market Price



                                       49
<PAGE>   53

per share of the Common Stock. If neither the Common Stock nor the Preferred
Stock is publicly held or so listed or admitted to trading or quoted, Current
Market Price per share of the Preferred Stock shall mean the fair value per
share as determined in good faith by the Board, whose determination shall be
described in a statement filed with the Rights Agent and shall be conclusive for
all purposes.

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



                                       50
<PAGE>   54

tion which mandates such adjustment, or (ii) the Expiration Date.

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

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



                                       51
<PAGE>   55

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

              (i) The Company may elect on or after the date of any adjustment
of the Purchase Price to adjust the number of Rights, in lieu of any adjustment
in the number of one one-thousandths of a share of Preferred Stock purchasable
upon the exercise of a Right. Each of the Rights outstanding after the
adjustment in the number of Rights shall be exercisable for the number of one
one-thousandths of a share of Preferred Stock for which a Right was exercisable
immediately prior to such adjust-



                                       52
<PAGE>   56

ment. 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-hundred-thousandth) obtained by dividing the Purchase Price in effect
immediately prior to adjustment of the Purchase Price by the Purchase Price in
effect immediately after adjustment of the Purchase Price. The Company shall
make a public announcement of its election to adjust the number of Rights,
indicating the record date for the adjustment, and, if known at the time, the
amount of the adjustment to be made. This record date may be the date on which
the Purchase Price is adjusted or any day thereafter, but, if the Rights
Certificates have been issued, shall be at least ten (10) days later than the
date of the public announcement. If Rights Certificates have been issued, upon
each adjustment of the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement



                                       53
<PAGE>   57

for the Rights Certificates held by such holders prior to the date of
adjustment, and upon surrender thereof, if required by the Company, new Rights
Certificates evidencing all the Rights to which such holders shall be entitled
after such adjustment. Rights Certificates so to be distributed shall be issued,
executed and countersigned in the manner provided for herein (and may bear, at
the option of the Company, the adjusted Purchase Price) and shall be registered
in the names of the holders of record of Rights Certificates on the record date
specified in the public announcement.

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

              (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then stated value, if any, of the number
of one one-thousandths of a share of Preferred Stock issuable upon



                                       54
<PAGE>   58

exercise of the Rights, the Company shall take any corporate action which may,
in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue fully paid and nonassessable such number of one
one-thousandths of a share of Preferred Stock at such adjusted Purchase Price.

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



                                       55
<PAGE>   59

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

              (n) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, (i) consolidate with any other Person (other
than a Subsidiary of the Company in a transaction which complies with Section
11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary
of the Company in a transaction which complies with Section 11(o) hereof), or
(iii) sell or transfer (or permit any Subsidiary to sell 



                                       56
<PAGE>   60

or transfer), in one transaction, or a series of related transactions, assets,
cash flow or earning power aggregating more than 50% of the assets or earning
power of the Company and its Subsidiaries (taken as a whole) to any other Person
or Persons (other than the Company or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(o) hereof), if (x) at the
time of or immediately after such consolidation, merger or sale there are any
rights, warrants or other instruments or securities outstanding or agreements in
effect which would substantially diminish or otherwise eliminate the benefits
intended to be afforded by the Rights or (y) prior to, simultaneously with or
immediately after such consolidation, merger or sale, the shareholders of the
Person who constitutes, or would constitute, the "Principal Party" for purposes
of Section 13(a) hereof shall have received a distribution of Rights previously
owned by such Person or any of its Affiliates and Associates.

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



                                       57
<PAGE>   61

such action will diminish substantially or otherwise eliminate the benefits
intended to be afforded by the Rights.

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



                                       58
<PAGE>   62

of which shall be the total number of shares of Common Stock of the Company
outstanding immediately following the occurrence of such event.

         Section 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES.
Whenever an adjustment is made as provided in Section 11 and Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Common Stock of the Company, a copy of such certificate
and (c) if a Distribution Date has occurred, mail a brief summary thereof to
each holder of a Rights Certificate in accordance with Section 25 hereof. The
Rights Agent shall be fully protected in relying on any such certificate and on
any adjustment therein contained.

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

              (a) In the event that, following the Stock Acquisition Date,
directly or indirectly, (x) the Company shall consolidate with, or merge with
and into, any other Person (other than a Subsidiary of the Company in a
transaction which complies with Section 11(o) here-



                                       59
<PAGE>   63

of), and the Company shall not be the continuing or surviving corporation of
such consolidation or merger, (y) any Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) hereof) shall
consolidate with, or merge with or into, the Company, and the Company shall be
the continuing or surviving corporation of such consolidation or merger and, in
connection with such consolidation or merger, all or part of the outstanding
shares of Common Stock of the Company shall be changed into or exchanged for
stock or other securities of any other Person or cash or any other property, or
(z) the Company shall sell or otherwise transfer (or one or more of its
Subsidiaries shall sell or otherwise transfer), in one transaction or a series
of related transactions, assets, cash flow or earning power aggregating more
than 50% of the assets, cash flow or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more transactions each of which
complies with Section 11(o) hereof), then, and in each such case (except as may
be contemplated by Section 13(d) hereof), proper provision shall be made so
that: (i) each holder of a Right, except as provided in Section 7(e) hereof,
shall thereafter have 



                                       60
<PAGE>   64

the right to receive, upon the exercise thereof at the then current Purchase
Price in accordance with the terms of this Agreement, such number of validly
authorized and issued, fully paid, non-assessable and freely tradeable shares of
Common Stock of the Principal Party (as such term is hereinafter defined), not
subject to any liens, encumbrances, rights of first refusal or other adverse
claims, as shall be equal to the result obtained by (1) multiplying the then
current Purchase Price by the number of one one-thousandths of a share of
Preferred Stock for which a Right is exercisable immediately prior to the first
occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred
prior to the first occurrence of a Section 13 Event, multiplying the number of
such one one-thousandths of a share for which a Right was exercisable
immediately prior to the first occurrence of a Section 11(a)(ii) Event by the
Purchase Price in effect immediately prior to such first occurrence), and
dividing that product (which, following the first occurrence of a Section 13
Event, shall be referred to as the "Purchase Price" for each Right and for all
purposes of this Agreement) by (2) 50% of the Current Market Price per share of
the Common Stock of such Principal Party on the date of consummation of such
Section 13 Event; (ii) such Princi-



                                       61
<PAGE>   65

pal Party shall thereafter be liable for, and shall assume, by virtue of such
Section 13 Event, all the obligations and duties of the Company pursuant to this
Agreement; (iii) the term "Company" shall thereafter be deemed to refer to such
Principal Party, it being specifically intended that the provisions of Section
11 hereof shall apply only to such Principal Party following the first
occurrence of a Section 13 Event; (iv) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
shares of its Common Stock) in connection with the consummation of any such
transaction as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to its
shares of Common Stock thereafter deliverable upon the exercise of the Rights;
and (v) the provisions of Section 11(a)(ii) hereof shall be of no effect
following the first occurrence of any Section 13 Event.

              (b) "Principal Party" shall mean:

                  (i) in the case of any transaction described in clause (x) or
         (y) of the first sentence of Section 13(a) hereof, the Person that is
         the issuer of any securities into which shares of Common Stock of the
         Com-



                                       62
<PAGE>   66

         pany are converted, changed or converted in such merger or
         consolidation, and if no securities are so issued, the Person that is
         the other party to such merger or consolidation; and

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

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



                                       63
<PAGE>   67

whichever of such Persons is the issuer of the Common Stock having the greatest
aggregate market value.

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

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



                                       64
<PAGE>   68

         at all times meeting the requirements of the Act) until the Expiration
         Date; and

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

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

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



                                       65
<PAGE>   69

been exercised shall thereafter become exercisable in the manner described in
Section 13(a) hereof.

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

         Section 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

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



                                       67
<PAGE>   71

consolidated transaction reporting system or as quoted by the Nasdaq National
Market with respect to securities listed or admitted to trading on another
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 or quoted by the Nasdaq National Market, respectively, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights, selected by the Board.
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
shall be used.

              (b) The Company shall not be required to issue fractions of shares
of Preferred Stock (other than fractions which are integral multiples of one
one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock). In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-thousandth



                                       68
<PAGE>   72

of a share of Preferred Stock, the Company may pay to the registered holders of
Rights Certificates at the time such Rights are exercised as herein provided an
amount in cash equal to the same fraction of the current market value of one
one-thousandth of a share of Preferred Stock. For purposes of this Section
14(b), the current market value of one one-thousandth of a share of Preferred
Stock shall be one one-thousandth of the closing price of a share of Preferred
Stock (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day
immediately prior to the date of such exercise.

              (c) Following the occurrence of a Triggering Event, the Company
shall not be required to issue fractions of shares of Common Stock of the
Company upon exercise of the Rights or to distribute certificates which evidence
fractional shares of Common Stock of the Company. In lieu of fractional shares
of Common Stock of the Company, the Company may pay to the registered holders of
Rights Certificates at the time such Rights are exercised as herein provided an
amount in cash equal to the same fraction of the current market value of one (1)



                                       69
<PAGE>   73

share of Common Stock of the Company. For purposes of this Section 14(c), the
current market value of one share of Common Stock of the Company shall be the
closing price of one share of Common Stock of the Company (as determined
pursuant to Section 11(d)(i) hereof) for the Trading Day immediately prior to
the date of such exercise.

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

         Section 15. RIGHTS OF ACTION. All rights of action in respect of this
Agreement are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock of the Company); and any registered holder of any Rights
Certificate (or, prior to the Distribution Date, of the Common Stock of the
Company), without the consent of the Rights Agent or of the holder of any other
Rights Certificate (or, prior to the Distribution Date, of the Common Stock of
the Company), may, in his own behalf and for his own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act



                                       70
<PAGE>   74

in respect of, his right to exercise the Rights evidenced by such Rights
Certificate in the manner provided in such Rights Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
shall be entitled to specific performance of the obligations hereunder and
injunctive relief against actual or threatened violations of the obligations
hereunder of any Person subject to this Agreement.

         Section 16. AGREEMENT OF RIGHTS HOLDERS. Every holder of a Right by
accepting the same consents and agrees with the Company and the Rights Agent and
with every other holder of a Right that:

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

              (b) after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office or offices of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper in-



                                       71
<PAGE>   75

strument of transfer and with the appropriate forms and certificates fully
executed;

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

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



                                       72
<PAGE>   76
administrative agency or commission, or any statute, rule, regulation or
executive order promulgated or enacted by any governmental authority,
prohibiting or otherwise restraining performance of such obligation; PROVIDED,
HOWEVER, the Company must use its reasonable efforts to have any such order,
decree or ruling lifted or otherwise overturned as soon as possible.

         Section 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of one
one-thousandths of a share of Preferred Stock or any other securities of the
Company which may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any Rights
Certificate be construed to confer upon the holder of any Rights Certificate, as
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in Section 25 hereof), or to receive dividends or subscription rights,
or otherwise,



                                       73
<PAGE>   77

until the Right or Rights evidenced by such Rights Certificate shall have been
exercised in accordance with the provisions hereof.

         Section 18. CONCERNING THE RIGHTS AGENT.

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

              (b) The Rights Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate or certificate for Common



                                       74

Stock of the Company or for other securities of the Company, instrument of
assignment or transfer, power of attorney, endorsement, affidavit, letter,
notice, direction, consent, certificate, statement, or other paper or document
believed by it to be genuine and to be signed, executed and, where necessary,
verified or acknowledged, by the proper Person or Persons.

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

              (a) Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the corporate trust, stock transfer or other shareholder services business of
the Rights Agent or any successor Rights Agent, shall be the successor to the
Rights Agent under this Agreement without the execution or filing of any paper
or any further act on the part of any of the parties hereto; but only if such
corporation would be eligible for appointment as a successor Rights Agent under
the provisions of Section 21 hereof. In case at the time such successor Rights
Agent shall succeed to the agency created by this Agreement,



                                       75
<PAGE>   79

any of the Rights Certificates shall have been countersigned but not delivered,
any such successor Rights Agent may adopt the countersignature of a predecessor
Rights Agent and deliver such Rights Certificates so countersigned; and in case
at that time any of the Rights Certificates shall not have been countersigned,
any successor Rights Agent may countersign such Rights Certificates either in
the name of the predecessor or in the name of the successor Rights Agent; and in
all such cases such Rights Certificates shall have the full force provided in
the Rights Certificates and in this Agreement.

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

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

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

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



                                       77
<PAGE>   81

any Assistant Secretary of the Company and delivered to the Rights Agent; and
such certificate shall be full authorization to the Rights Agent for any action
taken or suffered in good faith by it under the provisions of this Agreement in
reliance upon such certificate.

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

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

              (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Rights Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for



                                       78
<PAGE>   82

any adjustment required under the provisions of Section 11, Section 13 or
Section 24 hereof or responsible for the manner, method or amount of any such
adjustment or the ascertaining of the existence of facts that would require any
such adjustment (except with respect to the exercise of Rights evidenced by
Rights Certificates after actual notice of any such adjustment); nor shall it by
any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any shares of Common Stock of the Company or
Preferred Stock to be issued pursuant to this Agreement or any Rights
Certificate or as to whether any shares of Common Stock of the Company or
Preferred Stock will, when so issued, be validly authorized and issued, fully
paid and nonassessable.

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

              (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the



                                       79
<PAGE>   83

performance of its duties hereunder from the Chairman of the Board, the
President, any Vice President, the Secretary, any Assistant Secretary, the
Treasurer or any Assistant Treasurer of the Company, and to apply to such
officers for advice or instructions in connection with its duties, and it shall
not be liable for any action taken or suffered to be taken by it in good faith
in accordance with instructions of any such officer.

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

              (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or



                                       80
<PAGE>   84

agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct; PROVIDED, HOWEVER, reasonable care was exercised in the
selection and continued employment thereof.

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

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

         Section 21. CHANGE OF RIGHTS AGENT. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon



                                       81
<PAGE>   85

thirty (30) days' notice in writing mailed to the Company, and to each transfer
agent of the Common Stock of the Company and Preferred Stock, by registered or
certified mail, and, if such resignation occurs after the Distribution Date, to
the registered holders of the Rights Certificates by first-class mail. The
Company may remove the Rights Agent or any successor Rights Agent upon thirty
(30) days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Stock and
Preferred Stock, by registered or certified mail, and, if such removal occurs
after the Distribution Date, to the holders of the Rights Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of thirty (30) days after giving notice of such removal or after it has
been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Rights Certificate (who shall,
with such notice, submit his Rights Certificate for inspection by the Company),
then any registered holder of any Rights Certificate may apply to any court 



                                       82
<PAGE>   86

of competent jurisdiction for the appointment of a new Rights Agent. Any
successor Rights Agent, whether appointed by the Company or by such a court,
shall be (a) a legal business entity organized and doing business under the laws
of the United States or of the State of New York or of any other state of the
United States, in good standing, having an office in the State of New York,
which is authorized under such laws to exercise corporate trust or stock
transfer or shareholder services powers and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least
$50,000,000, (b) an affiliate of a legal business entity described in clause (a)
of this sentence or (c) the transfer agent for the Common Stock of the Company
and Preferred Stock. After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in



                                       83
<PAGE>   87

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

         Section 22. ISSUANCE OF NEW RIGHTS CERTIFICATES. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by the Board to reflect any adjustment or change in the
Purchase Price and the number or kind or class of shares or other securities or
property purchasable under the Rights Certificates made in accordance with the
provisions of this Agreement. In addition, in connection with the issuance or
sale of shares of Common Stock of the Company following the Distribution Date
and prior to the redemption or expiration of the Rights, the Company (a) shall,
with respect to shares of Common Stock of the Company so



                                       84
<PAGE>   88

issued or sold pursuant to the exercise of stock options or under any employee
plan or arrangement or upon the exercise, conversion or exchange of securities
hereafter issued by the Company, and (b) may, in any other case, if deemed
necessary or appropriate by the Board, issue Rights Certificates representing
the appropriate number of Rights in connection with such issuance or sale;
PROVIDED, HOWEVER, that (i) no such Rights Certificate shall be issued if, and
to the extent that, the Company shall be advised by counsel that such issuance
would create a significant risk of material adverse tax consequences to the
Company or the Person to whom such Rights Certificate would be issued, and (ii)
no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

         Section 23. REDEMPTION AND TERMINATION.

              (a) The Board may, at its option, at any time prior to the earlier
of (i) the close of business on the tenth Business Day (or such specified or
unspecified later date as may be determined by the Board before the rights cease
being redeemable) following the Stock Acquisition Date (or, if the Stock
Acquisition Date shall have occurred prior to the Record Date, the close of
business



                                       85
<PAGE>   89

on the tenth Business Day following the Record Date), or (ii) the Final
Expiration Date, direct the Company to, and if directed, the Company shall,
redeem all but not less than all of the then outstanding Rights at a redemption
price of $.01 per Right, as such amount may be appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof (such redemption price being hereinafter referred to as the "Redemption
Price"). Notwithstanding anything contained in this Agreement to the contrary,
the Rights shall not be exercisable after the first occurrence of a Section
11(a)(ii) Event until such time as the Company's right of redemption hereunder
has expired. The Company may, at its option, pay the Redemption Price in cash,
shares of Common Stock of the Company (based on the Current Market Price of the
Common Stock of the Company at the time of redemption) or any other form of
consideration deemed appropriate by the Board of Directors.

              (b) Immediately upon the action of the Board directing the
redemption of the Rights, evidence of which shall have been filed with the
Rights Agent and without any further action and without any notice, the right to
exercise the Rights will terminate and the only right thereafter of the holders
of Rights shall be to



                                       86
<PAGE>   90

receive the Redemption Price for each Right so held. Promptly after the action
of the Board directing the redemption of the Rights, the Company shall give
notice of such redemption to the Rights Agent and the holders of the then
outstanding Rights by mailing such notice to all such holders at each holder's
last address as it appears upon the registry books of the Rights Agent or, prior
to the Distribution Date, on the registry books of the transfer agent for the
Common Stock of the Company. Any notice which is mailed in the manner herein
provided shall be deemed given, whether or not the holder receives the notice.
Each such notice of redemption will state the method by which the payment of the
Redemption Price will be made.

              (c) Notwithstanding the provisions of Section 23(a) hereof, in the
event that a majority of the Board is elected by stockholder action by written
consent, or is comprised of persons elected at a meeting of stockholders who
were not nominated by the Board in office immediately prior to such meeting,
then for a period of one hundred and eighty (180) days following the
effectiveness of such election the Rights shall not be redeemed if such
redemption is reasonably likely to have the purpose or effect of allowing any
Person to become an



                                       87
<PAGE>   91

Acquiring Person or otherwise facilitating the occurrence of a Triggering Event
or a transaction with an Acquiring Person.

         Section 24. EXCHANGE.

              (a) The Board may, at its option, at any time after any Person
becomes an Acquiring Person, exchange all or part of the then outstanding and
exercisable Rights (which shall not include Rights that have become void
pursuant to the provisions of Section 7(e) hereof) for Common Stock of the
Company at an exchange ratio of one share of Common Stock per Right,
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Stock for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Stock of the Company then outstanding.



                                       88
<PAGE>   92

              (b) Immediately upon the action of the Board ordering the exchange
of any Rights pursuant to subsection (a) of this Section 24 and without any
further action and without any notice, the right to exercise such Rights shall
terminate and the only right thereafter of a holder of such Rights shall be to
receive that number of shares of Common Stock of the Company equal to the number
of such Rights held by such holder multiplied by the Exchange Ratio. The Company
shall promptly give public notice of any such exchange; PROVIDED, HOWEVER, that
the failure to give, or any defect in, such notice shall not affect the validity
of such exchange. The Company promptly shall mail a notice of any such exchange
to all of the holders of such Rights at their last addresses as they appear upon
the registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Common Stock of the Company 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



                                       89
<PAGE>   93

which have become void pursuant to the provisions of Section 7(e) hereof) held
by each holder of Rights.

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

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

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



                                       90
<PAGE>   94

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

         Section 25. NOTICE OF CERTAIN EVENTS.

              (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), or (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares
of Preferred Stock or shares of stock of any class or any other securities,



                                       91
<PAGE>   95

rights or options, or (iii) to effect any reclassification of its Preferred
Stock (other than a reclassification involving only the subdivision of
outstanding shares of Preferred Stock), or (iv) to effect any consolidation or
merger into or with any other Person (other than a Subsidiary of the Company in
a transaction which complies with Section 11(o) hereof), or to effect any sale
or other transfer (or to permit one or more of its Subsidiaries to effect any
sale or other transfer), in one transaction or a series of related transactions,
of more than 50% of the assets, cash flow or earning power of the Company and
its Subsidiaries (taken as a whole) to any other Person or Persons (other than
the Company or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), or (v) to effect the liquidation,
dissolution or winding up of the Company, then, in each such case, the Company
shall give to each holder of a Rights Certificate, to the extent feasible and in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, distribution of
rights or warrants, or the date on which such reclassification, consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to



                                       92
<PAGE>   96

take place and the date of participation therein by the holders of the shares of
Preferred Stock, if any such date is to be fixed, and such notice shall be so
given in the case of any action covered by clause (i) or (ii) above at least
twenty (20) days prior to the record date for determining holders of the shares
of Preferred Stock for purposes of such action, and in the case of any such
other action, at least twenty (20) days prior to the date of the taking of such
proposed action or the date of participation therein by the holders of the
shares of Preferred Stock whichever shall be the earlier.

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

         Section 26. NOTICES. Notices or demands authorized by this Agreement to

limitation, the right and power to (i) interpret the provisions of this
Agreement, and (ii) make all determinations deemed necessary or advisable for
the administration of this Agreement (including a determination to redeem or not
redeem the Rights or to amend the Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights and all other parties, and (y) not
subject the Board, or any of the directors on the Board to any liability to the
holders of the Rights.

         Section 30. BENEFITS OF THIS AGREEMENT. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the 



                                       97

registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock of the Company) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock of the Company).

         Section 31. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
PROVIDED, HOWEVER, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board determines
in its good faith judgment that severing the invalid language from this
Agreement would adversely affect the purpose or effect of this Agreement, the
right of redemption set forth in Section 23 hereof shall be reinstated



                                       98

and shall not expire until the close of business on the tenth Business Day
following the date of such determination by the Board. Without limiting the
foregoing, if any provision requiring a specific group of Directors of the
Company to act is held by any court of competent jurisdiction or other authority
to be invalid, void or unenforceable, such determination shall then be made by
the Board in accordance with applicable law and the Company's Certificate of
Incorporation and By-laws.

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

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

         Section 34. DESCRIPTIVE HEADINGS. Descriptive headings of the several
sections of this Agreement are inserted for convenience only and shall not
control or

                             WANG LABORATORIES, INC.


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


         We, Joseph M. Tucci, Chairman of the Board, and Albert A. Notini,
Secretary, the undersigned officers of Wang Laboratories, Inc., a corporation
organized and existing under the General Corporation Law of the State of
Delaware, in accordance with the provisions of Section 103 thereof, DO HEREBY
CERTIFY:

         That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the said Corporation, the said Board of
Directors on April 22, 1998, adopted the following resolution creating a series
of 100,000 shares of Preferred Stock designated as Series C Junior Participating
Preferred Stock:

         RESOLVED, that pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock of the Corporation be
and it hereby is created, and that the designation and amount thereof and the
voting powers, preferences and relative, participating, optional and other
special rights of the shares of such series, and the qualifications, limitations
or restrictions thereof are as follows:

         Section 1. DESIGNATION AND AMOUNT. The shares of such series shall be
designated as "Series C Junior Participating Preferred Stock" and the number of
shares constituting such series shall be One Hundred Thousand (100,000).

<PAGE>   105

         Section 2. DIVIDENDS AND DISTRIBUTIONS.

         (A) Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series C Junior Participating Preferred Stock with respect to dividends, the
holders of shares of Series C Junior Participating Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for the purpose, quarterly dividends payable in cash on
the 1st day of January, April, July and October in each year (each such date
being referred to herein as a "Quarterly Dividend Payment Date"), commencing on
the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series C Junior Participating Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the greater of (a)
$10.00 or (b) subject to the provision for adjustment hereinafter set forth,
1,000 times the aggregate per share amount of all cash dividends, and 1,000
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other distributions other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by reclassification
or otherwise), declared on the Common Stock, par value $0.01 per share, of the
Corporation (the "Common Stock") since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series C
Junior Participating Preferred Stock. In the event the Corporation shall at any
time after May 1, 1998 (the "Rights Declaration Date") (i) declare any dividend
on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount to which holders of
shares of Series C Junior Participating Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         (B) The Corporation shall declare a dividend or distribution on the
Series C Junior Participating 



                                       2
<PAGE>   106

Preferred Stock as provided in Paragraph (A) above immediately after it declares
a dividend or distribution on the Common Stock (other than a dividend payable in
shares of Common Stock); provided that, in the event no dividend or distribution
shall have been declared on the Common Stock during the period between any
Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend
Payment Date, a dividend of $10.00 per share on the Series C Junior
Participating Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

         (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series C Junior Participating Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares of Series
C Junior Participating Preferred Stock, unless the date of issue of such shares
is prior to the record date for the first Quarterly Dividend Payment Date, in
which case dividends on such shares shall begin to accrue from the date of issue
of such shares, or unless the date of issue is a Quarterly Dividend Payment Date
or is a date after the record date for the determination of holders of shares of
Series C Junior Participating Preferred Stock entitled to receive a quarterly
dividend and before such Quarterly Dividend Payment Date, in either of which
events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series C Junior Participating
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors may fix a record date for the determination of holders of shares of
Series C Junior Participating Preferred Stock entitled to receive payment of a
dividend or distribution declared thereon, which record date shall be no more
than 30 days prior to the date fixed for the payment thereof.

         Section 3. VOTING RIGHTS. The holders of shares of Series C Junior
Participating Preferred Stock shall have the following voting rights:

         (A) Subject to the provision for adjustment hereinafter set forth, each
share of Series C Junior Participating Preferred Stock shall entitle the holder
thereof to 1,000 votes on all matters submitted to a vote



                                       3
<PAGE>   107

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

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

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

                  (ii) During any default period, such voting right of the
         holders of Series C Junior Participating Preferred Stock may be
         exercised initially at a special meeting called pursuant to
         subparagraph (iii) of this Section 3(C) or at any annual meeting of
         stockholders, and



                                       4
<PAGE>   108

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

                  (iii) Unless the holders of Preferred Stock shall, during an
         existing default period, have previously exercised their right to elect
         directors, the Board of Directors may order, or any stockholder or
         stockholders owning in the aggregate not less than ten percent (10%) of
         the total number of shares of Preferred Stock outstanding, irrespective
         of series, may request, the calling of a special meeting of the holders
         of Preferred Stock, which meeting shall thereupon be called by the
         President, a Vice-President or the Secretary of the Corporation. Notice
         of such meeting and of



                                       5
<PAGE>   109

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

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

                  (v)  Immediately upon the expiration of a default period, (x)
         the right of the holders of Preferred Stock as a class to elect



                                       6
<PAGE>   110

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

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

         Section 4. CERTAIN RESTRICTIONS.

              (A) Whenever quarterly dividends or other dividends or
distributions payable on the Series C Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of Series
C Junior Participating Preferred Stock outstanding shall have been paid in full,
the Corporation shall not

                  (i)  declare or pay dividends on, make any other distributions
         on, or redeem or purchase or otherwise acquire for consideration any
         shares of stock ranking junior (either as to dividends or upon
         liquidation, dissolution or winding up) to the Series C Junior
         Participating Preferred Stock;

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



                                       7
<PAGE>   111

         ratably on the Series C Junior Participating Preferred Stock and all
         such parity stock on which dividends are payable or in arrears in
         proportion to the total amounts to which the holders of all such shares
         are then entitled;

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

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

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

         Section 5. REACQUIRED SHARES. Any shares of Series C Junior
Participating Preferred Stock purchased or otherwise acquired by the Corporation
in any manner whatsoever shall be retired and cancelled promptly after the
acquisition thereof. All such shares shall upon their cancellation become
authorized but unissued shares 



                                       8
<PAGE>   112

of Preferred Stock and may be reissued as part of a new series of Preferred
Stock to be created by resolution or resolutions of the Board of Directors,
subject to the conditions and restrictions on issuance set forth herein.

         Section 6. LIQUIDATION, DISSOLUTION OR WINDING UP. (A) Upon any
liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series C Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series C Junior Participating Preferred Stock
shall have received an amount equal to $1,000 per share of Series C
Participating Preferred Stock, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series C Liquidation Preference"). Following the payment of
the full amount of the Series C Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series C Junior
Participating Preferred Stock unless, prior thereto, the holders of shares of
Common Stock shall have received an amount per share (the "Common Adjustment")
equal to the quotient obtained by dividing (i) the Series C Liquidation
Preference by (ii) 1,000 (as appropriately adjusted as set forth in subparagraph
(C) below to reflect such events as stock splits, stock dividends and
recapitalizations with respect to the Common Stock) (such number in clause (ii),
the "Adjustment Number"). Following the payment of the full amount of the Series
C Liquidation Preference and the Common Adjustment in respect of all outstanding
shares of Series C Junior Participating Preferred Stock and Common Stock,
respectively, holders of Series C Junior Participating Preferred Stock and
holders of shares of Common Stock shall receive their ratable and proportionate
share of the remaining assets to be distributed in the ratio of the Adjustment
Number to 1 with respect to such Preferred Stock and Common Stock, on a per
share basis, respectively.

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



                                       9
<PAGE>   113

parity shares in proportion to their respective liquidation preferences. In the
event, however, that there are not sufficient assets available to permit payment
in full of the Common Adjustment, then such remaining assets shall be
distributed ratably to the holders of Common Stock.

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

         Section 7. CONSOLIDATION, MERGER, ETC. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash or any other property, then in any such case the shares of
Series C Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 1,000 times the aggregate amount
of stock, securities, cash or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the preceding sentence with respect to the exchange or
change of shares of Series C Junior Participating Preferred Stock shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 8. NO REDEMPTION. The shares of Series C Junior Participating
Preferred Stock shall not be redeemable.

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

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

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

         IN WITNESS WHEREOF, we have executed and subscribed this Certificate
and do affirm the foregoing as true under the penalties of perjury this ______
day of _______________, 1998.

conditions of the Rights Agreement, dated as of April 22, 1998 (the "Rights
Agreement"), between Wang Laboratories, Inc., a Delaware corporation (the
"Company"), and American Stock Transfer and Trust Company, a New York banking
corporation (the "Rights Agent"), to purchase from the Company at any time prior
to 5:00 P.M. (New York City time) on April 22, 2008 at the office or offices of

evidenced by this Rights Certificate (and the number of shares which may be
purchased upon exercise thereof) set forth above, and the Purchase Price per
share set forth above, are the number and Purchase Price as of _________ __,
____, based on the Preferred Stock as constituted at such date. The Company

                                        2
<PAGE>   117

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

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

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof



                                       3

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

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

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate may be redeemed by the Company at its option at a redemption
price of $.01 per Right at any time prior to the earlier of the close of
business on (i) the tenth business day following the Stock Acquisition Date (as
such time period may be extended pursuant to the Rights Agreement), and (ii) the
Final Expiration Date. The foregoing notwithstanding, the Rights generally may
not be redeemed for one hundred eighty (180) days following a change in a
majority of the Board as a result of a proxy contest. In addition, under certain
circumstances following the Stock Acquisition Date, the Rights may be exchanged,
in whole or in part, for shares of the Common Stock, or shares of preferred
stock of the Company having essentially the same value or economic rights as
such shares. Immediately upon the action of the Board authorizing any such
exchange, and without any further action or any notice, the Rights (other than
Rights which are not subject to such exchange) will terminate and the Rights
will only enable holders to receive the shares issuable upon such exchange.

         No fractional shares of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples



                                       5

of one one-thousandth of a share of Preferred Stock, which may, at the election
of the Company, be evidenced by depositary receipts), but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement. The Company, at its
election, may require that a number of Rights be exercised so that only whole
shares of Preferred Stock would be issued.

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

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK


         On April 22, 1998, the Board of Directors of Wang Laboratories, Inc.
(the "Company") declared a dividend distribution of one Right for each
outstanding share of Company Common Stock to stockholders of record at the close
of business on May 1, 1998 (the "Record Date"). Each Right entitles the
registered holder to purchase from the Company one one-thousandth of a share of
Series C Junior Participating Preferred Stock, par value $0.01 per share (the
"Series C Preferred Stock") at a Purchase Price of $120, subject to adjustment.
The description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") between the Company and American Stock Transfer and Trust
Company, as Rights Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. Subject to certain exceptions specified in the Rights Agreement,
the Rights will separate from the


<PAGE>   131

Common Stock and a Distribution Date will occur upon the earlier of (i)
10 business days (or such later date as the Board shall determine) following a
public announcement that a person or group of affiliated or associated persons
(an "Acquiring Person") has acquired beneficial ownership of 15% or more of the
outstanding shares of Common Stock, or, with respect to Ing. C. Olivetti & C.
S.p.A., has acquired beneficial ownership of more than 19.9% of the outstanding
shares of Common Stock (the "Stock Acquisition Date"), other than as a result of
repurchases of stock by the Company or certain inadvertent actions by
institutional or certain other stockholders or (ii) 10 business days (or such
later date as the Board shall determine) following the commencement of a tender
offer or exchange offer that would result in a person or group becoming an
Acquiring Person. Until the Distribution Date, (i) the Rights will be evidenced
by the Common Stock certificates and will be transferred with and only with such
Common Stock certificates, (ii) new Common Stock certificates issued after the
Record Date will contain a notation incorporating the Rights Agreement by
reference and (iii) the surrender for transfer of any certificates for Common
Stock outstanding will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificate. Pursuant to the Rights
Agreement, the Company reserves the right to require prior to the occurrence of
a Triggering Event (as defined below) that, upon any exercise 



                                       2
<PAGE>   132

of Rights, a number of Rights be exercised so that only whole shares of
Preferred Stock will be issued.

         The Rights are not exercisable until the Distribution Date and will
expire at 5:00 P.M. (New York City time) on April 22, 2008, unless such date is
extended or the Rights are earlier redeemed or exchanged by the Company as
described below.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights. 

         In the event that a Person becomes an Acquiring Person, except pursuant
to an offer for all outstanding shares of Common Stock which the independent
directors determine to be fair and not inadequate to and to otherwise be in the
best interests of the Company and its stockholders, after receiving advice from
one or more investment banking firms (a "Qualified Offer"), each holder of a
Right will thereafter have the right to receive, upon exercise, Common Stock
(or, in certain



                                       3
<PAGE>   133

circumstances, cash, property or other securities of the Company) having a value
equal to two times the exercise price of the Right. Notwithstanding any of the
foregoing, following the occurrence of the event set forth in this paragraph,
all Rights that are, or (under certain circumstances specified in the Rights
Agreement) were, beneficially owned by any Acquiring Person will be null and
void. However, Rights are not exercisable following the occurrence of the event
set forth above until such time as the Rights are no longer redeemable by the
Company as set forth below.

         For example, at an exercise price of $120 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following an event
set forth in the preceding paragraph would entitle its holder to purchase $240
worth of Common Stock (or other consideration, as noted above) for $120.
Assuming that the Common Stock had a per share value of $30 at such time, the
holder of each valid Right would be entitled to purchase 8 shares of Common
Stock for $120.

         In the event that, at any time following the Stock Acquisition Date,
(i) the Company engages in a merger or other business combination transaction in
which the Company is not the surviving corporation (other than



                                       4
<PAGE>   134
with an entity which acquired the shares pursuant to a Qualified Offer), (ii)
the Company engages in a merger or other business combination transaction in
which the Company is the surviving corporation and the Common Stock of the
Company is changed or exchanged (other than with an entity which acquired the
shares pursuant to a Qualified Offer), or (iii) 50% or more of the Company's
assets, cash flow or earning power is sold or transferred, each holder of a
Right (except Rights which have previously been voided as set forth above) shall
thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the exercise price of the
Right. The events set forth in this paragraph and in the second preceding
paragraph are referred to as the "Triggering Events."

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



                                       5
<PAGE>   135
         At any time until ten business days (or such later date as the Board
shall determine) following the Stock Acquisition Date, the Company may redeem
the Rights in whole, but not in part, at a price of $.01 per Right (payable in
cash, Common Stock or other consideration deemed appropriate by the Board of
Directors). Immediately upon the action of the Board of Directors ordering
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.01 redemption price. The foregoing
notwithstanding, the Rights generally may not be redeemed for one hundred eighty
(180) days following a change in a majority of the Board of Directors as a
result of a proxy contest.

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



                                       6
<PAGE>   136

         Any of the provisions of the Rights Agreement may be amended by the
Board prior to the Distribution Date. After the Distribution Date, the
provisions of the Rights Agreement may be amended by the Board in order to cure
any ambiguity, to make changes which do not adversely affect the interests of
holders of Rights, or to shorten or lengthen any time period under the Rights
Agreement.

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form
8-A/Current Report on Form 8-K dated May 15, 1998. A copy of the Rights
Agreement is available free of charge from the Rights Agent. This summary
description of the Rights does not purport to be complete and is qualified in
its entirety by reference to the Rights Agreement, which is incorporated herein
by reference.
