     Section 2.  Appointment of Rights Agent.  The Company hereby appoints the 
                 ---------------------------
Rights Agent to act as agent for the Company and the holders of the Rights (who,
in accordance with Section 3 hereof, shall prior to the Distribution Date also
be the holders of the Common Stock) in accordance with the terms and conditions
hereof, and the Rights Agent hereby accepts such appointment. The Company may
from time to time appoint such Co-Rights Agents as it may deem necessary or
desirable.

     Section 3.  Issue of Rights Certificates.
                 ----------------------------

       (a) Until the earlier of (i) the close of business on the tenth day after
the Stock Acquisition Date (or, if the tenth day after the Stock Acquisition
Date occurs before the Record Date, the close of business on the Record Date),
or (ii) the close of business on the tenth business day 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 plan) is first published or
sent or given within the meaning of Rule 14e-2(a) of the General Rules and
Regulations under the Exchange Act, if upon consummation thereof, such Person
would be the Beneficial Owner of shares of Voting Stock representing 28% or more
of the Voting Power (the earlier of (i) and (ii) being herein referred to as the
"Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of paragraph (b) of this Section 3) by the certificates for the
Common Stock registered in the names of the holders of the Common Stock (which
certificates for Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company). As soon as practicable after
the Distribution Date, the Rights Agent will send by first-class, insured,
postage prepaid mail, to each record holder of the Common Stock as of the close
of business on the Distribution Date, at the address of such holder shown on the
records of the Company, one or more 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
has been made pursuant to Section 11(p) hereof, at the time of distribution of
the Right 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) As promptly as practicable following the Record Date, the Company
will send a copy of a Summary of Rights, in substantially the form attached
hereto as Exhibit C (the "Summary of Rights"), by first-class, postage prepaid
mail, to each record holder of the Common Stock as of the close of business on
the Record Date, at the address of such holder shown on the records of the
Company. With respect to certificates for the Common Stock outstanding as of the
Record Date, until the Distribution Date, the Rights will be evidenced by such
certificates for the Common Stock and the registered holders of the Common Stock
shall also be the registered holders of the associated Rights. Until the earlier
of the Distribution Date or the Expiration Date (as such term is defined in
Section 7 hereof), the transfer of any certificates representing shares of
Common Stock in respect of which Rights have been issued shall also constitute
the transfer if the Rights associated with such shares of Common Stock.

       (c) Rights shall be issued in respect of all shares of Common Stock which
are issued 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 Armstrong World
Industries, Inc. (the "Company") and Morgan Guaranty Trust Company of New York
(the "Rights Agent") dated as of March 21, 1986 (the "Rights Agreement"), the
terms of which are hereby incorporated herein by reference and a copy of which
is on file at the principal offices of the Company. Under certain circumstances,
as set forth in the Rights Agreement, such Rights will be evidenced by separate
certificates and will no longer be evidenced by this certificate. The Company
will mail or cause to be mailed to the holder of this certificate a copy of the
Rights Agreement, as in effect on the date of mailing, without charge promptly
after receipt of a written request therefor. Under certain circumstances set
forth in the Rights Agreement, Rights issued to, or held by, any Person who is,
was or becomes an Acquiring Person or any Affiliate or Associates thereof (as
such terms are defined in the Rights Agreement), whether currently held by or on
behalf of such Persons or by any subsequent holder, may become null or void.
Rights will expire March 21, 1996 unless earlier redeemed as described in the
Rights Agreement.


                                       3

 
     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 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-hundredths of a share of Preferred Stock as 
shall be set forth therein at the price set forth therein (such exercise price 
per one one-hundredth of a share being hereinafter called 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) or Section 22 
hereof that represents Rights beneficially owned by:  (i) an Acquiring Person or
any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an 
Acquiring Person (or of any such Associate or Affiliate) who becomes a 
transferee after the Acquiring Person becomes such, or (iii) a transferee of an 
Acquiring Person (or of any such Associate or Affiliate) who becomes a 
transferee prior to or concurrently with the Acquiring Person becoming such and 
receives such Rights pursuant to either (A) a transfer (whether or not for 
consideration) from the Acquiring Person to holders of equity interests in such 
Acquiring Person or to any Person with whom such Acquiring Person has any 
continuing agreement, arrangement or understanding regarding the transferred 
Rights or (B) a transfer which the Board of Directors of the Company has 
determined is part of a plan, arrangement or understanding which has 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 such 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, any Vice-President or its Treasurer,
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 manually countersigned by the Rights
Agent and shall not be valid for any purpose unless so countersigned. In case
any officer of the Company who shall have signed any of the Rights Certificates
shall cease to be such officer of the Company before countersignature by the
Rights Agent and issuance and delivery by the Company, such Rights Certificates,
nevertheless, may be countersigned by the Rights Agent and issued and delivered
by the Company with the same force and effect as though the person who signed
such Rights Certificates had not ceased to be such officer of the Company; and
any Rights Certificates may be signed on behalf of the Company by any person
who, at the actual date of the execution of such Rights Certificate, shall be a
proper officer of the Company to sign such Rights Certificate, although at the
date of the execution of this Rights Agreement any such person was not such an
officer.

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

                                       4

 
     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 may be transferred, split up, combined or exchanged
for another Rights Certificate or Certificates, entitling the registered holder
to purchase a like number of one one-hundredths of a share of Preferred Stock
(or, following a Triggering Event, Common Stock, other securities, cash or other
assets, as the case may be) as the Rights Certificate or Certificates
surrendered then entitled such holder (or former holder in the case of a
transfer) to purchase. Any registered holder desiring to transfer, split up,
combine or exchange any Rights Certificate or Certificates shall make such
request in writing delivered to the Rights Agent, and shall surrender the Rights
Certificate or Certificates to be transferred, split up, combined or exchanged
at the principal office or offices of the Rights Agent designated for such
purpose. Neither the Rights Agent nor the Company shall be obligated to take any
action whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Section 4(b), Section 7(e) and Section 14 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.

     Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights.
                -------------------------------------------------------------
        (a) Subject to Section 7(e) hereof, the registered holder of any Rights
Certificate may exercise the Rights evidenced thereby (except as otherwise
provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and 
the certificate on the reverse side thereof duly executed, to the Rights Agent 
at the principal office or offices of the Rights Agent designated for such 
purpose, together with payment of the aggregate Purchase Price with respect to 
the total number of one one-hundredths of a share of Preferred Stock (or other 
securities, cash or other assets, as the case may be) as to which such 
surrendered Rights are then exercisable, at or prior to the earlier of (i) the 
close of business on March 21, 1996 (the "Final Expiration Date"), or (ii) the 
time at which the Rights are redeemed as provided in Section 23 hereof (the 
earlier of (i) and (ii) being herein referred to as the "Expiration Date").

        (b) The Purchase Price for each one one-hundredth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $175, and
shall be subject to adjustment from time to time as provided in Sections 11 and
13(a) hereof and shall be payable in accordance with paragraph (c) below (the
"Purchase Price").

        (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-hundredth of a share of Preferred Stock (or other
shares, securities, cash or other assets, as the case may be) to be purchased as
set forth below and an amount equal to any applicable transfer tax, the Rights
Agent shall, subject to Section 20(k) hereof, thereupon promptly (i) (A)
requisition from any transfer agent of the shares of Preferred Stock (or make
available, if the Rights Agent is the transfer agent for such shares)
certificates for the total number of one one-hundredths of a share of Preferred
Stock to be purchased and the Company hereby irrevocably authorizes its transfer
agent to comply with all such requests, or (B) if the Company shall have elected
to deposit the total number of shares of Preferred Stock issuable upon exercise
of the Rights hereunder with a depositary agent, requisition from the depositary
agent depositary receipts representing such number of one one-hundredths 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)


                                       5

 
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) may be 
made (x) in cash or by certified bank check or money order payable to the order 
of the Company, or (y) if the company shall in its sole discretion so consent, 
by delivery of a certificate or certificates (with appropriate stock powers 
executed in blank attached thereto) evidencing a number of shares of Common 
Stock equal to the then Purchase Price divided by the closing price (as 
determined pursuant to Section 11(d) hereof) per share of Common Stock on the 
Trading Date immediately preceding the date of such exercise.  In the event that
the Company is obligated to issue other securities (including Common Stock) of 
the Company, pay cash and/or distribute other property pursuant to Section 11(a)
hereof, the Company will make all arrangements necessary so that such other 
securities, cash and/or other property are available for distribution by the 
Rights Agent, if and when appropriate.

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

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

     Section 8. Cancellation and Destruction of Rights Certificates.  All Rights
                ---------------------------------------------------
Certificates surrendered for the purpose of exercise, transfer, split up, 
combination or exchange shall, if surrendered to the Company or any of its 
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights 
Certificates shall be issued in lieu thereof except as expressly permitted by 
any of the provisions of this Agreement.  The Company shall deliver to the 
Rights Agent for cancellation and retirement, and the Rights Agent shall so 
cancel and retire, any other Rights 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.

                                       6







 
     Section 9. Reservation and Availability of Capital Stock.
                --------------------------------------------- 

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

       (b) So long as the shares of Preferred Stock (and, following the 
occurrence of a Triggering Event, Common Stock and/or other securities) issuable
and deliverable upon the exercise of the Rights may be listed on any national
securities exchange, 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 Section
11(a)(iii) Event on which the consideration to be delivered by the Company upon 
exercise of the Rights has been determined in accordance with Section 11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration statement under the Securities Act of 1933 (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
date of the expiration of the Rights. The Company will also take such action as
may be appropriate under, or to ensure compliance with, the securities or "blue
sky" laws of the various states in connection with the exercisability of the
Rights. The Company may temporarily suspend, for a period of time not to exceed
ninety (90) days after the date set forth in clause (i) of the first sentence of
this Section 9(c), the exercisability of the Rights in order to prepare and file
such registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained.

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

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

     Section 10. Preferred Stock Record Date. Each person in whose name any
                 ---------------------------
certificate for a number of one one-hundredths of a share of Preferred Stock (or
Common Stock and/or other securities, as the case may be) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of such fractional shares of Preferred Stock (or Common Stock and/or
other securities, as the case may be) represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
                                              --------
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or

                                       7

 
other securities, as the case may be) transfer books of the Company are closed, 
such Person shall be deemed to have become the record holder of such shares 
(fractional or otherwise) on, and such certificate shall be dated, the next 
succeeding Business Day on which the Preferred Stock (or Common Stock and/or 
other securities, as the case may be) transfer books of the Company are open.  
Prior to the exercise of the Rights evidenced thereby, the holder of a Rights 
Certificate shall not be entitled to any rights of a stockholder of the Company 
with respect to shares for which the Rights shall be exercisable, including, 
without limitation, the right to vote, to receive dividends or other 
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

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

       (a)(i)  In the event the Company shall at any time after the date of this
Agreement (A) declare a dividend on the Preferred Stock payable in shares of 
Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine the 
outstanding Preferred Stock into a smaller number of shares, or (D) issue any 
shares of its capital stock in a reclassification of the Preferred Stock 
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), except
as otherwise provided in this Section 11(a) and Section 7(e) hereof, the
Purchase Price in effect at the time of the 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 Rights exercised after such time shall be entitled to receive, upon
payment of the Purchase Price then in effect, the aggregate number and kind of
shares of Preferred Stock or capital stock, as the case may be, which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Stock transfer books of the Company were open, he 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:

               (A) any Acquiring Person or any Associate or Affiliate of any 
Acquiring Person, at any time after the date of this Agreement, directly or 
indirectly, shall merge into the Company or otherwise combine with the Company 
and the Company shall be the continuing or surviving corporation of such merger 
or combination and the Common Stock of the Company shall remain outstanding and 
unchanged, or

               (B) 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 plan), alone or together with 
its Affiliates and Associates, shall, at any time after the Rights Declaration 
Date, become the Beneficial Owner of shares of Voting Stock representing 28% or 
more of the Voting Power, other than pursuant to any transaction set forth in 
Section 13(a) hereof.

then, promptly following five (5) days after the date of the occurrence of
an event described in Section 11(a)(ii)(B) hereof and promptly following the
occurrence of an event described in Section 11(a)(ii)(A) hereof, 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
exercise thereof at the then current Purchase Price in accordance with the terms
of this Agreement, in lieu of a number of one one-hundredths of a share of
Preferred Stock, such number of shares of Common Stock of the Company as shall
equal the result obtained by (x) multiplying the then current Purchase Price by
the then number of one one-hundredths of a share of Preferred Stock for which a
Right was exercisable immediately prior to the first occurrence of a Section
11(a)(ii) Event, and (y) dividing that product (which, following such first
occurrence, shall thereafter be referred to as the "Purchase Price" for each
Right and for all purposes of this Agreement) by 50% of the current market price
(determined pursuant to Section 11(d) hereof) per share of Common Stock on the
date of such first occurrence (such number of shares hereinafter referred to as
the "Adjustment Shares").

                                       8

 
       (iii) In the event that the number of shares of Common Stock which are 
     authorized by the Company's Articles of Incorporation but not outstanding
     or reserved for issuance for purposes other than upon exercise of the
     Rights are not sufficient to permit the exercise in full of the Rights in
     accordance with the foregoing subparagraph (ii) of this Section 11(a), the
     Company shall: (A) determine the excess of (1) the value of the Adjustment
     Shares issuable upon the exercise of a Right (the "Current Value") over (2)
     the Purchase Price (such excess, the "Spread"), and (B) with respect to
     each Right, make adequate provision to substitute for the Adjustment
     Shares, upon payment of the applicable Purchase Price, (1) cash, (2) a
     reduction in the Purchase Price, (3) Common Stock or other equity
     securities of the Company (including, without limitation, shares, or units
     of shares, of preferred stock which the Board of Directors of the Company
     has deemed to have the same value as shares of Common Stock (such shares of
     preferred stock, "common stock equivalents")), (4) debt securities of the
     Company, (5) other assets, or (6) any combination of the foregoing, having
     an aggregate value equal to the Current Value, where such aggregate value
     has been determined by the Board of Directors of the Company based upon the
     advice of a nationally recognized investment banking firm selected by the
     Board of Directors of the Company; provided, however, if the Company shall
                                        --------
     not have made adequate provision to deliver value pursuant to clause (B)
     above within thirty (30) days following the later of (x) the first
     occurrence of a Section 11(a)(ii) Event and (y) the date on which the
     Company's right of redemption pursuant to Section 23(a) expires (the later
     of (x) and (y) being referred to herein as the "Section 11(a)(ii) Trigger
     Date"), then the Company shall be obligated to deliver, upon the surrender
     for exercise of a Right and without requiring payment of the Purchase
     Price, shares of Common Stock (to the extent available) and then, if
     necessary, cash, which shares and/or cash have an aggregate value equal to
     the Spread. If the Board of Directors of the Company shall determine in
     good faith that it is likely that sufficient additional shares of Common
     Stock could be authorized for issuance upon exercise in full of the Rights,
     the thirty (30) day period set forth above may be extended to the extent
     necessary, but not more than ninety (90) days after the Section 11(a)(ii)
     Trigger Date, in order that the Company may seek shareholder approval for
     the authorization of such additional shares (such period, as it may be
     extended, the "Substitution Period"). To the extent that the Company
     determines that same action need be taken pursuant to the first and/or
     second sentences of this Section 11(a)(iii), the Company (x) shall provide,
     subject to Section 7(e) hereof, that such action shall apply uniformly to
     all outstanding Rights, and (y) may suspend the exercisability of the
     Rights until the expiration of the Substitution Period in order to seek any
     authorization of additional shares and/or to decide the appropriate form of
     distribution to be made pursuant to such first sentence. In the event of
     any such suspension, the Company shall issue a public announcement stating
     that the exercisability of the Rights has been temporarily suspended, as
     well as a public announcement at such time as the suspension is no longer
     in effect. For purposes of this Section 11(a)(iii), the value of the Common
     Stock shall be the current market price (as determined pursuant to Section
     11(d) hereof) per share of the Common Stock on the Section 11(a)(ii)
     Trigger Date and the value of any "common stock equivalent" shall be deemed
     to have the same value as the Common Stock 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 price (as determined pursuant to Section 11(d) hereof) 
per share of Preferred Stock on such record date, the Purchase Price to be in 
effect after such record date shall be determined by multiplying the Purchase 
Price in effect immediately prior to such record date by a fraction, the 
numerator of which shall be the number of shares of Preferred Stock outstanding 
on such record date, plus the number of shares of Preferred Stock which the 
aggregate offering price of the total number of shares of Preferred Stock and/or
equivalent preferred stock so to be offered (and/or the aggregate initial 
conversion price of the convertible securities so to be offered) would purchase 
as such current market price, and the denominator of which shall be the number 
of shares of Preferred Stock outstanding on such record date, plus the number 
of additional shares of Preferred Stock and/or equivalent preferred stock to be 
offered for subscription or purchase (or into which the convertible securities 
so to be offered are initially convertible).  In case such subscription price 
may be paid by delivery of consideration part or all of which may be in a form 
other than cash, the value of such consideration shall be as determined in good 
faith by the Board of Directors of the Company, whose determination shall be 
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and the holders of the Rights.  Shares of Preferred Stock

                                       9

 
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 if effect if such record date had not 
been fixed.

     (c) In case the Company shall fix a record date for distribution to all 
holders of Preferred Stock (including any such distribution made in connection 
with a consolidation or merger in which the Company is the continuing 
corporation) of evidences of indebtedness, cash (other than a regular quarterly 
cash dividend out of the earnings or retained earnings of the Company), assets 
(other than a dividend payable in Preferred Stock, but including any dividend 
payable in stock other than Preferred Stock) or subscription rights or warrants 
(excluding those referred to in Section 11(b) hereof), the Purchase Price to be 
in effect after such record date shall be determined by multiplying the 
Purchase Price in effect immediately prior to such record date by a fraction, 
the numerator of which shall be the current market price (as determined pursuant
to Section 11(d) hereof) per share of Preferred Stock on such record date, less 
the fair market value (as determined in good faith by the Board of Directors of 
the Company, whose determination shall be described in a statement filed with 
the Rights Agent) of the portion of the cash, assets or evidences of 
indebtedness so to be distributed or of such subscription rights or warrants 
applicable to a share of Preferred Stock and the denominator of which shall be 
such current market price (as determined pursuant to Section 11(d) hereof) per 
share of Preferred Stock.  Such adjustments shall be made successively whenever 
such a record date is fixed, and in the event that such distribution is not so 
made, the Purchase Price shall be adjusted to be the Purchase Price which would 
have been in effect if such record date had not been fixed.

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

                                      10


 
          (ii) For the purpose of any computation hereunder, the "current market
       price" per share of Preferred Stock shall be determined in the same
       manner as set forth above for the Common Stock in clause (i) of this
       Section 11(d) (other than the last sentence thereof). If the current
       market price per share of Preferred Stock cannot be determined in the
       manner provided above or if the Preferred Stock is not publicly held or
       listed or traded in a manner described in clause (i) of this Section
       11(d), the "current market price" per share of Preferred Stock shall be
       conclusively deemed to be an amount equal to 100 (as such number may be
       appropriately adjusted for such events as stock splits, stock dividends
       and recapitalizations with respect to the Common Stock occurring after
       the date of this Agreement) multiplied by the current market price per
       share of the Common Stock. If neither the Common Stock nor the Preferred
       Stock is publicly held or so listed or traded, "current market price" per
       share of the Preferred Stock shall mean the fair value per share as
       determined in good faith by the Board of Directors of the Company,
       whose determination shall be described in a statement filed with the
       Rights Agent and shall be conclusive for all purposes. For all purposes
       of this Agreement, the "current market price" of one-hundredth of a
       share of Preferred Stock shall be equal to the "current market price" of
       one share of Preferred Stock divided by 100.


       (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 of one-millionth of a share of Preferred Stock, as the case may 
be. Notwithstanding the first sentence of this Section 11(e), any adjustment 
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the transaction which mandates such adjustment, or
(ii) the Expiration Date.

       (f) If as a result of an adjustment made pursuant to Section 11(a)(ii) or
Section 13(a) hereof, the holder of any Right thereafter exercised shall become 
entitled to receive any shares of capital stock other than Preferred Stock, 
thereafter 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 Section 11(a), (b), 
(c), (e), (g), (h), (i), (j), (k) and (m), and the provisions of Sections 7, 9, 
10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like 
terms to any such other shares.

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

       (h) 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 Section 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-hundredths of a
share of Preferred Stock (calculated to the nearest one-millionth) obtained by 
(i) multiplying (x) the number of one one-hundredths 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-hundredths 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-hundredths of a 
share of Preferred Stock for which a Right was exercisable immediately prior to 
such adjustment. Each Right held of record prior to such adjustment of the 
number of Rights shall become that number of Rights (calculated to the nearest 
one ten-thousandth) obtained by dividing the Purchase Price in effect 
immediately prior to adjustment of the  Purchase Price by the Purchase Price in 
effect immediately after adjustment of the Purchase Price. The Company shall 
make a public announcement of its election to adjust the number of Rights, 
indicating the record date for the adjustment, and, if known at the time, the 
amount of the adjustment to be made. This record date may be the date on which 
the Purchase Price is adjusted or any day thereafter, but, if the Rights 
Certificates have been issued, shall be at least ten (10) days later than the 
date of the public announcement. If Rights Certificates have been issued, upon 
each adjustment of the number of Rights pursuant to this Section 11(i), the 
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Rights Certificates on such record date Rights Certificates 
evidencing, subject to Section 14


                                      11


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

       (j) Irrespective of any adjustment or change in the Purchase Price or the
number of one one-hundredths of a share of Preferred Stock issuable upon the
exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per one one-hundredth of a
share and the number of one one-hundredth 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-hundredths of a share of Preferred Stock issuable upon exercise of the 
Rights, the Company shall take any corporate action which may, in the opinion of
its counsel, be necessary in order that the Company may validly and legally 
issue fully paid and nonassessable such number of one one-hundredths 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-hundredths of a share of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of one one-hundreths 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 is effect prior to such adjustment; provided, 
                                                                --------
however, that the company shall deliver to such holder a due bill or other 
appropriate instrument evidencing such holder's right to receive such 
additional shares (fractional or otherwise) or securities upon the occurrence of
the event requiring such adjustment.

       (m) Anything in this Section 11 to the contrary notwithstanding, the 
company shall be entitled to make such reductions in the Purchase Price, in 
addition to those adjustments expressly required by this Section 11, as and to 
the extent that in their good faith judgment the Board of Directors of the 
Company 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 shareholders.

       (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 is a transaction which complies with Section 11(o) 
hereof), (ii) merge with or into any other Person (other than a Subsidiary of 
the Company in a transaction which complies with Section 11(o) hereof), or (iii)
sell or transfer (or permit any Subsidiary to sell or transfer), in one
transaction or a series of related transactions, assets or earning power 
aggregating more than 50% of the assets or earning power of the Company and its 
Subsidiaries (taken as a whole) to any other Person or Persons (other than the 
Company and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), if (x) at the time of or immediately after 
such consolidation, merger 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 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 reasonable foreseeable that such action will diminish substantially or 
otherwise eliminate the benefits intended to be afforded by the Rights.

                                      12

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

     Section 12.  Certificate of Adjusted Purchase Price or Number of Shares.
                  ----------------------------------------------------------
Whenever an adjustment is made as provided in Section 11 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, a copy of such certificate, and (c) mail a
brief summary thereof to each holder of a Rights Certificate (or, if prior to
the Distribution Date, to each holder of a certificate representing shares of
Common Stock) in accordance with Section 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 of Sale or Transfer of Assets 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) hereof), and the Company shall not
be the continuing or surviving corporation of such consolidation or merger, (y)
any Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof) shall consolidate with, or merge with or
into, the Company, and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such
consolidation or merger, all or part of the outstanding shares of Common Stock
shall be changed into or exchanged for stock or other securities of any other
Person or cash or any other property, or (z) the Company shall sell or otherwise
transfer (or one or more of its Subsidiaries shall sell or otherwise transfer),
in one transaction or a series of related transactions, assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more transactions each of which
complies with Section 11(o) hereof), then, and in each such case, proper
provision shall be made so that: (i) each holder of a Right, except as provided
in Section 7(e) hereof, shall thereafter have the right to receive, upon the
exercise thereof at the then current Purchase Price in accordance with the terms
of this Agreement, 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-hundredths 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-hundredths 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 (2) dividing that product (which, following the
first occurrence of a Section 13 Event, shall be referred to as the "Purchase
Price" for each Right and for all purposes of this Agreement) by 50% of the
current market price (determined pursuant to Section 11(d)(i) hereof) per share
of the Common Stock of such Principal Party on the date of consummation of such
Section 13 Event; (ii) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such Section 13 Event, all the obligations and duties
of the Company pursuant to this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of Section 11 hereof shall apply only to such
Principal Party following the first occurrence of a Section 13 Event; (iv) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of shares of its Common Stock) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof shall thereafter be applicable, as nearly as reasonably
may be, in relation to its shares of Common Stock thereafter deliverable upon
the exercise of the Rights; and (v) the provisions of Section 11 (a)(ii) hereof
shall be of no effect following the first occurrence of any Section 13 Event.

                                      13

 
     (b) "Principal Party" shall mean

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

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

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

     (c) The Company shall not consummate any such consolidation, merger, sale 
or transfer unless the Principal Party shall have a sufficient number of 
authorized shares of its Common Stock which have not been issued or reserved for
issuance to permit the exercise in full of the Rights in accordance with the 
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 at all
       times meeting the requirements of the Act) until the Expiration Date; and

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

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

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

                                      14

 
market maker making a market in the Rights selected by the Board of Directors 
of the Company. If on any such date no such market maker is making a market in 
the Rights the fair value of the Rights on such date as determined in good faith
by the Board of Directors of the Company shall be used.

       (b) The company shall not be required to issue fractions of shares of 
Preferred Stock (other than fractions which are integral multiples of one one-
hundredth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock). In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-hundredth 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-hundredth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market value of
one one-hundredth of a share of Preferred Stock shall be one one-hundredth of
the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of
such exercise.

       (c) Following the occurrence of a Triggering Event, the Company shall not
be required to issue fractions of shares of Common Stock upon exercise of the 
Rights or to distribute certificates which evidence fractional shares of Common 
Stock. In lieu of fractional shares of Common Stock, the Company 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) share of Common Stock. For purposes of this Section 
14(c), the current market value of one share of Common Stock shall be the 
closing price of one share of Common Stock (as determined pursuant to Section 
11(d)(i) hereof) for the Trading Day immediately prior to the date of such 
exercise.

       (d) The holder of a Right by the acceptance of the Rights expressly 
waives 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); and any registered holder of any Rights Certificate (or, 
prior to the Distribution Date, of the Common Stock), without the consent of the
Rights Agent or of the holder of any other Rights Certificate (or, prior to the 
Distribution Date, of the Common Stock), may, in his own behalf and for his own 
benefit, enforce, and may institute and maintain any suit, action or proceeding 
against the Company to enforce, or otherwise act in respect of, his right to 
exercise the Rights evidenced by such Rights Certificate in the manner provided 
in such Rights Certificate and in this Agreement. Without limiting the foregoing
or any remedies available to the holders of Rights, it is specifically 
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and 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 earlier of the Distribution Date and the Expiration 
Date, the Rights will be transferable only in connection with the transfer of 
Common Stock;

       (b) after the Distribution Date, the Rights Certificates are transferable
only on the registry books of the Rights Agent if surrendered at the principal
office or offices of the Rights Agent designated for such purposes, duly
endorsed or accompanied by a proper instrument of transfer and with the
appropriate forms and certificates fully executed;
 
       (c) subject to Section 6(a) and Section 7(f) hereof, the Company and the 
Rights Agent may deem and treat the person in whose name a Rights Certificate 
(or, prior to the Distribution Date, the associated Common Stock certificate) is
registered as the absolute owner thereof and of the Rights evidenced thereby
(notwithstanding any notations of ownership or writing on the Rights
Certificates or the associated Common Stock certificate made by anyone other
than the Company or the Rights Agent) for all purposes whatsoever, and neither
the Company nor the Rights Agent, subject to the last sentence of Section 7(e)
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 of other order, decree
     

                                      15


 
or ruling issued by a court of competent jurisdiction or by a governmental, 
regulatory or administrative agency or commission, or any statute, rule, 
regulation or executive order promulgated or enacted by any governmental 
authority, prohibiting or otherwise restraining performance of such obligation; 
provided, however, the Company must use its best efforts to have any such order,
- --------
decree 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-hundredths of a
share of Preferred Stock or any other securities of the Company which may at any
time be issuable on the exercise of the Rights represented thereby, nor shall 
anything contained herein or in any Rights Certificate be construed to confer 
upon the holder of any Rights Certificate, as such, any of the rights of a 
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 24 hereof), 
or to receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights Certificate shall have been exercised in 
accordance with the provisions hereof.

     Section 18. Concerning the Rights Agent.
                 ---------------------------
       (a) The Company agrees to pay to the Rights Agent reasonable compensation
for all services rendered by it hereunder and, from time to time, on demand of 
the Rights Agent, its reasonable expenses and counsel fees and disbursements and
other disbursements incurred in the administration and execution of this 
Agreement and the exercise and performance of its duties hereunder. The Company 
also agrees to indemnify the Rights Agent for, and to hold it harmless against, 
any loss, liability, or expense, incurred without negligence, bad faith or 
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability 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 Stock or for other securities of the 
Company, instrument of assignment or transfer, power of attorney, endorsement, 
affidavit, letter, notice, direction, consent, certificate, statement, or other 
paper or document believed by it to be genuine and to be signed, executed and, 
where necessary, verified or acknowledged, by the proper Person or Persons.

    Section 19. Merger or Consolidation or Change of Name of Rights Agent.
                ---------------------------------------------------------
       (a) Any corporation into which the Rights Agent or any successor Rights 
Agent may be merged or with which it may be consolidated, or any corporation 
resulting from any merger or consolidation to which the Rights Agent or any 
successor Rights Agent shall be a party, or any corporation succeeding to the 
corporate trust business or stock transfer business of the Rights Agent or any 
successor Rights Agent, shall be the successor to the Rights Agent under this 
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto; provided, however, that such corporation 
                                   --------
would be eligible for appointment as a successor Rights Agent under the 
provisions of Section 21 hereof. In case at the time such successor Rights Agent
shall succeed to the agency created by this Agreement, any of the Rights 
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of a predecessor Rights Agent and 
deliver such Rights Certificates so countersigned; and in case at that time any 
of the Rights Certificates shall not have been countersigned, any successor 
Rights Agent may countersign such Rights Certificates either in the name of the 
predecessor or in the name of the successor Rights Agent; and in all such cases 
such Rights Certificates shall have the full force provided in the Rights 
Certificates and in this Agreement.

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

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

                                      16

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

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

       (g) The Rights Agent is hereby authorized and directed to accept 
instructions with respect to the performance of its duties hereunder from the 
Chairman of the Board, the President, any Vice-President, the Secretary, or the
Treasurer of the Company, and to apply to such officers for advice or 
instructions in connection with its duties, and it shall not be liable for any 
action taken 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 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.

                                      17

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

     Section 21.  Change of Rights Agent.  The Rights Agent or any successor 
                  ----------------------
Rights Agent may resign and be discharged from its duties under this Agreement 
upon thirty (30) days' notice in writing mailed to the Company, and to each 
transfer agent of the Common Stock and Preferred Stock, by registered or 
certified mail, and to the holders of the Rights Certificates by first-class 
mail.  The Company may remove the Rights Agent or any successor Rights Agent 
upon thirty (30) days' notice in writing, mailed to the Rights Agent or 
successor Rights Agent, as the case may be, and to each transfer agent of the
Common Stock and Preferred Stock, by registered or certified mail, and to the
holders of the Rights Certificates by first-class mail. If the Rights Agent
shall resign or be removed or shall otherwise become incapable of acting, the
Company shall appoint a successor to the Rights Agent. If the Company shall fail
to make such appointment within a period of thirty (30) days after giving notice
of such removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a
Rights Certificate (who shall, with such notice, submit his Rights Certificate
for inspection by the Company), then any registered holder of any Rights
Certificate may apply to any court of competent jurisdiction for the appointment
of a new Rights Agent. Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be (a) a corporation organized and doing
business under the laws of the United States or of the State of New York (or of
any other state of the United States so long as such corporation is authorized
to do business as a banking institution in the State of New York), in good
standing, having a principal office in the State of New York, which is
authorized under such laws to exercise corporate trust or stock transfer powers
and is subject to supervision or examination by federal or state authority and
which has at the time of its appointment as Rights Agent a combined capital and
surplus of at least $100,000,000 or (b) an Affiliate controlled by a corporation
described in clause (a). After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock and the Preferred Stock, and mail a notice thereof in writing
to the registered holders of the Rights Certificates. Failure to give any notice
provided for in this Section 21, 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 its Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind of class of shares or other 
securities or property purchasable under the Rights Certificates made in 
accordance with the provisions of this Agreement.  In addition, in connection 
with the issuance or sale of shares of Common Stock following the Distribution 
Date and prior to the redemption or expiration of the Rights, the Company (a) 
shall, with respect to shares of Common Stock so issued or sold pursuant to the 
exercise of stock options or under any employee plan or arrangement, or upon the
exercise, conversion or exchange of securities hereinafter issued by the 
Company, and (b) may, in any other case, if deemed necessary or appropriate by 
the Board of Directors of the Company, issue Rights Certificates representing 
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 of Directors of the Company may, at its option, at any 
time prior to 5:00 P.M., New York City time, on the earlier of (i) the close of 
business on the tenth day following the Stock Acquisition Date (or, if the Stock
Acquisition Date shall have occurred prior to the Record Date, the close of 
business on the tenth day following the Record Date), or (ii) the Final 
Expiration Date, redeem all but not less than all the then outstanding Rights at
a redemption price of $.05 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"); provided, however, if the Board of 
                                        --------
Directors of the Company authorizes redemption 

                                      18

 
of the Rights in either of the circumstances set forth in clauses (i) and (ii) 
below, then there must be Disinterested Directors then in office and such 
authorization shall require the concurrence of a majority of such Disinterested 
Directors: (i) such authorization occurs on or after the time a Person becomes 
an Acquiring Person, or (ii) such authorization occurs on or after the date of a
change (resulting from a proxy or consent solicitation) in a majority of the 
directors in office at the commencement of such solicitation if any Person who 
is a participant in such solicitation has stated (or, if upon the commencement 
of such solicitation, a majority of the Board of Directors of the Company has 
determined in good faith) that such Person (or any of its Affiliates or 
Associates) intends to take, or may consider taking, any action which would 
result in such Person becoming an Acquiring Person or which would cause the 
occurrence of a Triggering Event unless, concurrent with such solicitation, such
Person (or one or more of its Affiliates or Associates) is making a cash tender 
offer pursuant to a Schedule 14D-1 (or any successor form) filed with the
Securities and Exchange Commission for all outstanding shares of Common Stock
not beneficially owned by such Person (or by its Affiliates or Associates);
provided further, however, that if, following the occurrence of a Stock
- ----------------
Acquisition Date and following the expiration of the right of redemption
hereunder but prior to any Triggering Event, (i) a Person who is an Acquiring
Person shall have transferred or otherwise disposed of a number of shares of
Common Stock in one transaction, or series of transactions, not directly or
indirectly involving the Company or any of its Subsidiaries, which did not
result in the occurrence of a Triggering Event such that such Person is not
thereafter a Beneficial Owner of shares of Voting Stock representing more than
10% of the Voting Power, and (ii) there are no other Persons, immediately
following the occurrence of the event described in clause (i), who are Acquiring
Persons,then the right of redemption shall be reinstated and thereafter be
subject to the provisions of this Section 23. 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.

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

     Section 24. 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 or the Company), or (ii) to offer to the holders of Preferred Stock 
rights or warrants to subscribe for or to purchase any additional shares of 
Preferred Stock or shares of stock of any class or any other securities, rights 
or options, or (iii) to effect any reclassification of its Preferred Stock 
(other than a reclassification involving only the subdivision of outstanding 
shares of Preferred Stock), or (iv) to effect any consolidation or merger into 
or with any other Person (other than a Subsidiary of the Company in a 
transaction which complies with Section 11(o) hereof), or to effect any sale or 
other transfer (or to permit one or more of its Subsidiaries to effect any sale 
or other transfer), in one transaction or a series of related transactions, of 
more than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person or Persons (other than the Company and/or
any of its Subsidiaries in one or more transactions each of which complies with
Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding
up of the Company, then, in each such case, the Company shall give to each
holder of a Rights Certificate, to the extent feasible and in accordance with
Section 25 hereof, a notice of such proposed action, which shall specify the
record date for the purposes of such stock dividend, distribution of rights or
warrants, or the date on which such reclassification, consolidation, merger,
sale, transfer, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of the shares of Preferred Stock,
if any such date is to be fixed, and such notice shall be so given in the case
of any action covered by clause (i) or (ii) above at least twenty (20) days
prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action, at
least twenty (20) days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the shares of Preferred
Stock whichever shall be the earlier.

                                      19

 
       (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 25 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Section 
11(a)(ii) hereof, and (ii) all references in the preceding paragraph to 
Preferred Stock shall be deemed thereafter to refer to Common Stock and/or, if 
appropriate, other securities.

Distribution Date, the interests of the holders of Rights shall be deemed 
coincident with the interests of the holders of Common Stock.

- --------
contrary, if any such term, provision, covenant or restriction is held by such

in preference to the holders of Common Stock and shares of stock ranking junior
as to dividends to the Series One Preferred Stock, shall be entitled to receive,
when and if declared by the Board of Directors out of funds legally available
for the purpose, quarterly dividends payable in cash on the 15th day of March,
June, September and December 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 a
fraction of a share of Series One Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to the greater of (a) $32.50 of (b) subject
to the provision for adjustment hereinafter set forth, 100 times the aggregate
per share amount of all cash dividends plus 100 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), paid on
the Common Stock at any time during the quarter year immediately preceding the
quarter year ending on the day immediately preceding such Quarterly Dividend
Payment Date. In the event the Corporation shall at any time after March 21,
1986 (the "Rights Declaration Date") during any quarter year immediately
preceding the quarter year ending on the day immediately preceding a Quarterly
Dividend Payment Date (i) declare any dividend on Common Stock payable in shares
of Common Stock, or (ii) subdivide the outstanding Common Stock or combine the
outstanding Common Stock into a greater or lesser number of shares of Common
Stock, then in each such case the amounts to which holders of shares of Series
One Preferred Stock were entitled immediately prior to such event under clause
(b) of the preceding sentence shall be adjusted by multiplying each 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.

     Dividends shall begin to accrue and be cumulative on outstanding shares of
Series One Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series One Preferred Stock, 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 Series One 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
One 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 One Preferred Stock entitled to receive payment of a dividends 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. Except as otherwise provided by law, holders of 
                -------------
shares of Series One Preferred Stock shall have no voting rights.

     Section 4. Certain Restrictions.
                --------------------

       (A) Whenever quarterly dividends or other dividends or distributions 
payable on the Series One 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 One 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 as to assets) to
          the Series One 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 as
          to assets) with the Series One Preferred Stock, except dividends paid
          ratably on the Series One 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 junior (either as to dividends or as to assets)
          to the Series One Preferred Stock, provided that the Corporation may
          at any time redeem, purchase or otherwise acquire shares of any such
          junior stock in exchange for shares of any stock of the Corporation
          ranking junior (either as to dividends or as to assets) to the Series
          One Preferred Stock; or

          (iv) purchase or otherwise acquire for consideration any shares of
          Series One Preferred Stock, or any shares of stock ranking on a parity
          (either as to dividends or upon liquidation, dissolution or winding
          up) with the Series One 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 One 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 of 
Class A Preferred Stock and may be reissued as part of a new series of Class A 
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. Subject to the rights 
                --------------------------------------
and preferences of the holders of any shares of $3.75 Cumulative Preferred Stock
and of any series of Class A Preferred Stock ranking senior as to assets to this
Series One Preferred Stock, (A) Upon any involuntary or voluntary liquidation, 
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 as to 
assets) to the Series One Preferred Stock unless, prior thereto, the holders of 
shares of Series One Preferred Stock shall have received an amount per share 
equal to the Per Share Series One Liquidation Preference. The Per Share Series 
One Liquidation Preference shall be equal to the sum of (x) $100.00 plus an 
amount equal to accrued and unpaid dividends and distributions thereon, whether 
or not declared, to the date of such payment, plus (y) the Participation 
Preference. The "Participation Preference" is an amount per each share of Series
One Preferred Stock outstanding, equal to the product of (A) the Excess 
Distribution Amount, as hereinafter defined times (B) a fraction whose numerator
is 100 and whose denominator is the sum of (i) the product of 100 times the 
number of outstanding shares of Series One Preferred Stock, plus (ii) the 
product of 100 times a fraction whose numerator is the number of outstanding 
shares of Common Stock and whose denominator is the Adjustment Number; provided 
however, if the foregoing computation results in a negative number, then the 
Participation Preference shall be 0. Following the payment of the full amount of
the Series One Liquidation Preference, holders of shares of Common Stock shall 
receive the remaining assets to be distributed.

     The "Excess Distribution Amount" is an amount equal to the amount available
for distribution to shareholders of the Corporation after payment of all debts 
and liabilities less the sum of (i) the liquidation preferences in respect of 
all shares of preferred stock of the Corporation other than the Series One 
Preferred Stock, (ii) the product of 100 times the number of outstanding shares 
of Series One Preferred Stock, and (iii) the product of the number of 
outstanding shares of Common Stock times a fraction whose numerator is 100 and 
whose denominator is the Adjustment Number.

 
       (B) The Adjustment Number shall initially be 100 and shall be subject to 
adjustment as provided in this subsection (B). 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 and/or any other property, then in any such case the shares of 
Series One 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 100 times the aggregate amount of stock, 
securities, cash and/or any other property (payable in kind), as the case may 
be, into which or for which each share of Common Stock is changed or exchanged. 
In the event the Corporation shall at any time (i) declare any dividend on 
Common Stock payable in shares of Common Stock, or (ii) subdivide the 
outstanding Common Stock or combine the outstanding Common Stock into a greater 
or lesser number of shares of Common Stock, then in each such case the amount 
set forth in the preceding sentence with respect to the exchange or change of 
shares of Series One 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. Redemption. The outstanding shares of Series One Preferred Stock
                ----------
may be redeemed at the option of the Board of Directors as a whole, but not in
part, at any time, or from time to time, at a cash price per share equal to (i)
the product of the Adjustment Number times the Average Market Value, as such
term is hereinafter defined, of the Common Stock, plus (ii) all dividends which
on the redemption date have accrued on the shares to be redeemed and have not
been paid or declared and a sum sufficient for the payment thereof set apart,
without interest; provided, however, that if and whenever any quarter-yearly
dividend shall have accrued on the Series One Preferred Stock which has not been
paid or declared and a sum sufficient for the payment thereof set apart, the
Corporation may not purchase or otherwise acquire any shares of Series One
Preferred Stock unless all shares of such stock at the time outstanding are so
purchased or otherwise acquired. The "Average Market Value" is the average of
the closing sale prices of the Common Stock during the 30-day period immediately
preceding the date before the redemption date on the Composite Tape for New
York Stock Exchange-Listed Stocks, or, if such stock is not quoted on the
Composite Tape, on the New York Stock Exchange, or, if such stock is not listed
on such Exchange, on the principal United States securities exchange registered
under the Securities Exchange Act of 1934, as amended, on which such stock is
listed, or, if such stock is not listed on any such exchange, the average of the
closing bid quotations with respect to a share of Common Stock during such 30-
day period on the National Association of Securities Dealers, Inc. Automated
Quotations System or any system then in use, or if no such quotations are
available, the fair market value of the Common Stock as determined by the Board
of Directors in good faith.

     Section 9. Fractional Shares. Series One Preferred Stock may be issued in 
                -----------------
fractions of a share which shall entitle the holder, in proportion to such 
holders fractional shares, to exercise voting rights, if applicable, receive 
dividends, participate in distributions and to have the benefit of all other 
rights of holders of Series One Preferred Stock.

     The foregoing resolution was duly adopted at a meeting of the Board of 
Directors of the Corporation duly called and held on March 11, 1986, at which 
meeting a quorum was present and acting throughout.


 
                                                                       EXHIBIT B

                       ARMSTRONG WORLD INDUSTRIES, INC.

     This certifies that                        , or registered assigns,
is the registered owner of the number of Rights set forth above, each of which 
entitles the owner thereof, subject to the terms, provisions and conditions of

Preferred Stock (the "Preferred Stock") of the Company, at a purchase price of 
$175 per one one-hundredth of a share (the "Purchase Price"), upon presentation 
and surrender of this Rights Certificate with the Form of Election to Purchase 
and related Certificate duly executed. The Purchase Price shall be paid in cash

Stock of the Company having an equivalent value. The number of Rights evidenced 
by this Rights Certificate (and the number of shares which may be purchased upon
exercise thereof) set forth above, and the Purchase Price per share set forth

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

holder hereof shall have any right with respect to such Rights from and after
the occurrence of such Section 11(a)(ii) Event.

______________
*  The portion of the legend in brackets shall be inserted only if applicable
   and shall replace the preceding sentence.

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

     This Rights Certificate is subject to all of the terms, provisions and 
conditions of the Rights Agreement, which terms, provisions and conditions are 
hereby incorporated herein by reference and made a part hereof and to which 
Rights Agreement reference is hereby made for a full description of the rights, 
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the office of the Company and are
also available upon written request to the Company.

     This Rights Certificate, with or without other Rights Certificates, upon 
surrender at the principal office or offices of the Rights Agent designated for 
such purpose, may be exchanged for another Rights Certificate or Rights 
Certificates of like tenor and date evidencing Rights entitling the holder to

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 $.05 per Right at any time prior to the earlier of the close of 
business on (i) the tenth day following the Stock Acquisition Date (as such 
number of days may be extended), and (ii) the Final Expiration Date. Under 
certain circumstances set forth in the Rights Agreement, the decision to redeem 
shall require the concurrence of a majority of the Disinterested Directors. 
Thereafter, the Company's right of redemption may be reinstated if an Acquiring 
Person reduces his beneficial ownership to shares of Voting Stock representing 
10% or less of the Voting Power in a transaction or series of transactions not 
involving the Company.

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

     No holder of this Rights Certificate shall be entitled to vote or receive 
dividends or be deemed for any purpose the holder of shares of Preferred Stock 
or of any other securities of the Company which may at any time be issuable on

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 or withhold consent to 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 March 11, 1986, the Board of Directors of Armstrong World Industries, 
Inc. (the "Company") declared a distribution of one Right for each outstanding 
share of Common Stock of the Company to stockholders of record at the close of 
business on March 21, 1986 and with respect to each share of Common Stock that 
may be issued by the Company prior to the "Distribution Date" (or the earlier 
redemption or expiration of the Rights) described below. Upon the occurrence of 
certain events described below each Right would entitle the registered holder to
purchase from the Company, a unit consisting of one one-hundredth of a share (a 
"Unit") of Series One of Class A Preferred Stock, without par value (the 
"Preferred Stock") at a Purchase Price of $175 per Unit, subject to adjustment. 
The Purchase Price shall be paid in cash or, if the Company shall in its sole 
discretion so consent, shares of Common Stock having a value at the time of 
exercise equal to the Purchase Price. The description and terms of the Rights 
are set forth in a Rights Agreement (the "Rights Agreement") between the Company
and Morgan Guaranty Trust Company of New York, as Rights Agent.

     The Rights will be attached to all Common Stock certificates representing 
shares then outstanding until the occurrence of a Distribution Date or the 
earlier redemption or expiration of the Rights. No separate Rights Certificates 
                                                -------------------------------
will be distributed unless and until a Distribution Date occurs. A Distribution 
- ---------------------------------------------------------------
Date will occur and the Rights will separate from the Common Stock upon the 
earlier to occur of (i) 10 days following a public announcement that a person or
group of affiliated or associated persons (an "Acquiring Person") has acquired, 
or obtained the right to acquire, beneficial ownership of shares of the 
Company's capital stock representing 20% or more of the voting power of all 
outstanding shares of capital stock of the Company (the date of such 
announcement being referred to as the "Stock Acquisition Date"), or (ii) 10 
business days following the commencement of a tender offer or exchange offer 
that would result in a person or group beneficially owning outstanding shares of
the Company's capital stock representing 28% or more of the voting power of all 
outstanding shares of capital stock of the Company. 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 March 21, 1986, will contain a notation 
incorporating the Rights Agreement by reference, and (iii) the surrender for 
transfer of any certificates for Common Stock will also constitute the transfer 
of the Rights associated with the Common Stock represented by such certificate.

     The Rights are not exercisable unless and until a Distribution Date and 
will expire at the close of business on March 21, 1996, unless earlier redeemed 
by the Company as described below.

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

     In the event that, at any time following the Distribution Date, (i) the 
Company is the surviving corporation in a merger with an Acquiring Person and 
its Common Stock is not changed or exchanged, or (ii) a Person becomes the 
beneficial owner of shares of the Company's capital stock representing 28% or 
more of the voting power of all outstanding shares of capital stock of the 
Company, 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 
any of the events described in item (i) or (ii) 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,
the Rights are not exercisable following the occurrence of either of the events 
set forth in this paragraph until such time as the Rights are no longer 
redeemable by the Company as set forth below.

     For example, at an exercise price of $175 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 $350 worth
of Common Stock (or other consideration, as noted above) for $175. Assuming that
the Common Stock had a per share value of $87 1/2 at such time, the holder of 
each valid Right would be entitled to purchase four shares of Common Stock for 
$175.

 
     In the event that, at any time following the Stock Acquisition Date, (i) 
the Company is acquired in certain merger or other business combination 
transactions (other than a merger described in the second preceding paragraph) 
or (ii) 50% or more of the Company's assets or earning power is sold or 
transferred, each holder of a Right (except Rights which previously have been 
voided as set forth above) shall thereafter have the right to receive, upon 
exercise, common stock of the acquiring company having a value equal to two 
times the exercise price of the Right.

     The right to purchase Common Stock of the Company or common stock of an 
acquiring company at a discount in the circumstances described in the preceding 
paragraphs would not be exercisable if the Right holder has previously exercised
the right to purchase Preferred Stock.

     The Purchase Price payable, and the number of Units of Preferred Stock or 
other securities or property issuable, upon exercise of the Rights are subject 
to adjustment from time to time to prevent dilution (i) in the event of a stock 
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock, (ii) if holders of the Preferred Stock are granted certain rights or 
warrants to subscribe for Preferred Stock or convertible securities at less than
the current market price of the Preferred Stock, or (iii) upon the distribution
to holders of the Preferred Stock of evidences of indebtedness or assets
(excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

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

     At any time until ten days after the Stock Acquisition Date, the Company 
may redeem the Rights in whole, but not in part, at a price of $.05 per Right. 
The redemption period may be extended by the Company's Board of Directors at 
any time prior to the expiration of such period. Under certain circumstances set
forth in the Rights Agreement, the decision to redeem shall require the 
concurrence of a majority of the Disinterested Directors. After the redemption 
period has expired, the Company's right of redemption may be reinstated if an 
Acquiring Person reduces his beneficial ownership to shares of capital stock of 
the Company representing 10% of less of the voting power of all outstanding 
shares of capital stock of the Company in a transaction or series of 
transactions not involving the Company. Immediately upon the action of the Board
of Directors ordering redemption of the Rights, with, where required, the 
concurrence of a majority of the Disinterested Directors, the Rights will 
terminate and the only right of the holders of Rights will be to receive the 
$.05 redemption price.

     The term "Disinterested Directors" means any member of the Board of 
Directors of the Company who was a member of the Board prior to the time that 
the Acquiring Person became an Acquiring Person, any person who is subsequently 
elected to the Board to fill a vacancy created by an increase in the size of 
the Board if such person is recommended or approved by a majority of the 
Disinterested Directors, and any successor of a Disinterested Director if such 
person is recommended or approved by a majority of the Disinterested Directors, 
but shall not include an Acquiring Person, or an affiliate or associate of an 
Acquiring Person, or any representative of the foregoing entities.

     Until a Right is exercised, the holder thereof, as such, will have no 
rights as a stockholder of the Company arising from the Right itself, including,
without limitation, the right to vote or to receive dividends. While the initial
declaration and distribution of the Rights will not be taxable to the 
stockholders or 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 an 
acquiring company as set forth above.

     Under the Plan, the Board has broad amendatory powers. Other than those 
provisions relating to the principal economic terms of the Rights, any of the 
provisions of the Rights Agreement may be amended by the Board of Directors of 
the Company prior to the Distribution Date. After the Distribution Date, the 
provisions of the Rights Agreement may be amended by the Board (in certain 
circumstances with the concurrence of the Disinterested Directors) in order to 
cure any ambiguity, to make other changes which do not adversely affect the 
interests of holders of Rights (excluding the interests of any Acquiring 
Person), or to shorten or lengthen any time period under the Rights Agreement; 
provided, however, that no amendment to adjust the time period governing 
- --------
redemption shall be made at such time as the Rights are not redeemable.

     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 filed 
on March 21, 1986. A copy of the Rights Agreement is available free of charge 
from the Company. 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.
