Item 5.           Other Events.

                  On August 23, 1996, the Board of Directors of The Dexter
Corporation (the "Company") determined that it was desirable and in the best
interests of the Company and its stockholders for the Company to extend the
Company's existing rights by adopting a shareholders rights plan substantially
similar to the Company's current rights plan, which expires on November 17,
1996. Pursuant to the new Rights Agreement between the Company and ChaseMellon
Shareholder Services, L.L.C., as rights agent (the "Rights Agreement"), one
right will be issued for each outstanding share of common stock, par value $1
per share, of the Company on the earlier to occur of expiration of the existing
rights (November 17, 1996), or the redemption of such rights in accordance with
the terms of the Company's existing rights plan. Each of the new Rights will
entitle the registered holder to purchase from the Company one two-hundredth of
a share of Series A Junior Participating Preferred Stock at a price of $90.00
per one two-hundredth of a share. The new rights are redeemable under certain
circumstances at a redemption price of $.01 per Right and will expire, unless
earlier redeemed, on August 31, 2006.

                  The description and terms of the new Rights are more fully set
forth in the Rights Agreement, a copy of which is filed herewith and is
incorporated herein by reference.

                  WHEREAS, on August 23, 1996 (the "Rights Dividend Declaration
Date"), the Board of Directors of the Company authorized and declared a dividend
distribution of one Right for each share of Common Stock of the Company
outstanding upon the Expiration Date (as defined in the 1986 Agreement) (the

shares of Common Stock outstanding due to the repurchase of shares of Common
Stock by the Company, unless and until such Person shall purchase or otherwise
become the Beneficial Owner of additional shares of Common Stock


                                        2

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 A
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 Rights
Certificates, the Company shall make the necessary and appropriate rounding
adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights. As of and after the Distribution Date,
the Rights will be evidenced solely by such Rights Certificates.

                           (b) 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 have stamped on, impressed on, printed on, written or otherwise affixed to
them the following legend or such similar legend as the Company may deem
appropriate and is 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 Rights may from time to time be listed, or to conform to usage:

                  This certificate also evidences and entitles the holder
         hereof to certain Rights as set forth in the Rights Agreement, dated as
         of August 23, 1996 (the "Rights Agreement"), between The Dexter
         Corporation and ChaseMellon Shareholder Services, L.L.C., as Rights
         Agent, the terms of which are hereby incorporated herein by reference
         and a copy of which is on file at the principal offices of The Dexter
         Corporation. 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 Dexter Corporation
         will mail to the holder of this certificate a copy of the Rights


                                        7
<PAGE>   11
         Agreement, as in effect on the date of mailing, without charge promptly
         after receipt of a written request therefor. Under certain
         circumstances set forth in the Rights Agreement, Rights issued to, or
         held by, any Person who is, was or becomes an Acquiring Person or any
         Affiliate or Associate (as such terms are defined in the Rights
         Agreement) thereof, whether currently held by or on behalf of such
         Person or by any subsequent holder, may become null and void.

With respect to such certificates containing the foregoing legend and
certificates containing the legend specified in the 1986 Agreement and with
respect to previously issued certificates that contain no comparable 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 A hereto with such
changes, 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 two-hundredths
of a share of Preferred Stock as shall be set forth therein at the price set
forth therein (such exercise price per one two-hundredth of a share, the
"Purchase Price"), but the amount and type of securities purchasable upon the
exercise


                                        8
<PAGE>   12
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 as a
primary purpose or effect avoidance of Section 7(e) hereof, and any Rights
Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer,
exchange, replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain and be subject to the following legend or such
similar legend as the Company may deem appropriate and is 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:

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

                  Section 5. Countersignature and Registration.

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

                  Section 6. Transfer, Split Up, Combination and Exchange of
Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.
(a) Subject to the provisions of Section 4(b), Section 7(e) and Section 14
hereof, at any time after the close of business on the Distribution Date, and at
or prior to the close of business on the Expiration Date, any Rights Certificate
or Certificates may


                                       10
<PAGE>   14
be transferred, split up, combined or exchanged for another Rights Certificate
or Certificates, entitling the registered holder to purchase a like number of
one two-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, with the forms of assignment and transfer
appropriately executed, 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 or the Rights Agent 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 Purchase Price with respect to the total
number of one two-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
August 31, 2006 (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 two-hundredth of
a share of Preferred Stock pursuant to the exercise of a Right shall initially
be $90, 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.

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


                                       12
<PAGE>   16
depositary agent, requisition from the depositary agent depositary receipts
representing such number of one two-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) and the Company will direct the depositary agent to comply
with such request, (ii) when appropriate, 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) when appropriate, 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 bank draft payable to the order of the
Company, or (y) 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 Day (as such term is hereinafter defined) 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. The
Company reserves the right to require prior to the occurrence of a Triggering
Event that, upon any exercise of Rights, a number of Rights be exercised so that
only whole shares of Preferred Stock would be issued.

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


                                       13
<PAGE>   17
such holder, subject to the provisions of Section 14 hereof.

                           (e) Notwithstanding anything in this Agreement to
the contrary, from and after the occurrence of the 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 any of its
Affiliates, Associates or transferees hereunder.

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

                  Section 8. Cancellation and Destruction of Rights
Certificates. All Rights Certificates surrendered for the purpose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the
Company or any of its stock transfer 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.

                  Section 9. Reservation and Availability of Capital Stock;
Listing and Registration. (a) The Company shall 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, if any) issuable 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 (i) to
file, as soon as practicable following the earliest date after the occurrence of
the Section 11(a)(ii) Event on which the consideration to be delivered by the
Company upon


                                       15
<PAGE>   19
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
"Securities Act"), with respect to the securities purchasable upon exercise of
the Rights on an appropriate form, (ii) to cause such registration statement to
become effective as soon as practicable after such filing, and (iii) to cause
such registration statement to remain effective (with a prospectus at all times
meeting the requirements of the Securities 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 if the requisite qualification in
such jurisdiction shall not have been obtained, the exercise thereof shall not
be permitted under applicable law or a registration statement shall not have
been declared effective.

                           (d) The Company shall take all such action as may be
necessary to ensure that all one two-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 shall 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


                                       16
<PAGE>   20
delivery of the Rights Certificates and of any certificates for a number of one
two-hundredths of a share of Preferred Stock (or Common Stock and/or other
securities, if any, as the case may be) upon the exercise of Rights. The Company
shall not, however, be required to pay any transfer tax which may be payable in
respect of any transfer or delivery of Rights Certificates to a Person other
than, or the issuance or delivery of a number of one two-hundredths of a share
of Preferred Stock (or Common Stock and/or other securities, if any, as the case
may be) in respect of a name other than that of, the registered holder of the
Rights Certificates evidencing Rights surrendered for exercise or to issue or
deliver any certificates for a number of one two-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 two-hundredths of a share of Preferred
Stock (or Common Stock and/or other securities, if any, 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 to the
extent permissible under applicable law (or Common Stock and/or other
securities, if any, as the case may be) represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or other securities, if any, 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 securities on, and such certificate shall be dated, the next
succeeding Business Day on which the Preferred Stock (or Common Stock and/or
other securities, if any, 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


                                       17
<PAGE>   21
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
Securities or Number of Rights. The Purchase Price, the number and kind of
securities covered by each Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 11.

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


                                       18
<PAGE>   22
         the adjustment provided for in this Section 11(a)(i) shall be in
         addition to, and shall be made prior to, any adjustment required
         pursuant to Section 11(a)(ii) hereof.

                                    (ii) In the event any Person (other than the
         Company, any Subsidiary of the Company, any employee benefit or stock
         ownership plan of the Company or of any Subsidiary of the Company, or
         any Person organized, appointed or established by the Company for or
         pursuant to the terms of any such plan), alone or together with its
         Affiliates and Associates, shall, at any time after the Rights Dividend
         Declaration Date, become the Beneficial Owner of 20% or more of the
         shares of Common Stock then outstanding, unless the event causing the
         20% threshold to be crossed is a transaction set forth in Section 13(a)
         hereof, or is an acquisition of shares of Common Stock pursuant to a
         tender offer or an exchange offer for all outstanding shares of Common
         Stock at a price and on terms determined by at least a majority of the
         entire Board of Directors of the Company to be in the best interests of
         the Company and its stockholders (hereinafter, a "Qualifying Offer"),

then, promptly following the occurrence of such event, proper provision shall be
made so that each holder of a Right (except as provided below and in Section
7(e) hereof) shall thereafter have the right to receive, upon exercise thereof
at the then current Purchase Price in accordance with the terms of this
Agreement, in lieu of a number of one two-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 two-hundredths of a share of Preferred Stock for which a Right
was exercisable immediately prior to the occurrence of the Section 11(a)(ii)
Event, and (y) dividing that product (which, following such 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
occurrence (such number of shares, the "Adjustment Shares").

                                    (iii) In the event that the number of shares
         of Common Stock which are authorized by the Company's Restated
         Certificate 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 (subject to Section 7(e) hereof), make adequate
         provision to substitute for the Adjustment Shares, upon the exercise of
         Right and payment of the applicable Purchase Price, (1) cash, (2) a
         reduction in the Purchase Price, (3) Common Stock or other equity
         securities of the Company (including, without limitation, shares 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 being referred to herein as "common
         stock equivalents")), (4) debt securities of the Company, (5) other
         assets, or (6) any combination of the foregoing, having an aggregate
         value equal to the Current Value, where such aggregate value has been
         determined by the 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 occurrence of the 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


                                       20
<PAGE>   24
         an aggregate value equal to the Spread. If the Board of Directors of
         the Company shall determine in good faith that it is likely that
         sufficient additional shares of Common Stock could be authorized for
         issuance upon exercise in full of the Rights, the thirty (30) day
         period set forth above may be extended to the extent necessary, but not
         more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in
         order that the Company may seek stockholder approval for the
         authorization of such additional shares (such period, as it may be
         extended, the "Substitution Period"). To the extent that the Company
         determines that some 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 and to determine the value thereof. In the event
         of any such suspension, the Company shall issue a public announcement
         stating that the exercisability of the Rights has been temporarily
         suspended, as well as a public announcement at such time as the
         suspension is no longer in effect. For purposes of this Section
         11(a)(iii), the value of each Adjustment Share shall be the current
         market price (as determined pursuant to Section 11(d) hereof) per share
         of Common Stock on the Section 11(a)(ii) Trigger Date and the per share
         or per unit value of any "common stock equivalent" shall be deemed to
         equal to the per share current market price (as determined pursuant to
         Section 11(d) hereof) of the Common Stock on such date. If and to the
         extent that the Board of Directors of the Company shall have
         determined that any legal or contractual restrictions prevent the
         Company from paying any amounts required to be paid hereunder in
         accordance with this Section 11(a)(iii), the Company shall pay to the
         holders of Rights as to which such payments are being


                                       21
<PAGE>   25
         made all amounts which are not then restricted on a pro rata basis. The
         Company shall continue to make payments on a pro rata basis as funds
         become available until such payments have been paid in full.

                           (b) In the event that 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
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
at such current market price, and the denominator of which shall be the number
of shares of Preferred Stock outstanding on such record date, plus the number of
additional shares of Preferred Stock and/or equivalent preferred stock to be
offered for subscription or purchase (or into which the convertible securities
so to be offered are initially convertible). In case such subscription price may
be paid by delivery of consideration part or all of which may be in a form other
than cash, the value of such consideration shall be as determined in good faith
by the Board of Directors of the Company, whose determination shall be described
in a statement filed with the Rights Agent and shall be conclusive for all
purposes. Shares of Preferred Stock owned by or held for the account of the
Company shall not be deemed outstanding for the purpose of any such computation.
Such adjustment shall be made successively whenever such a record date is fixed,
and


                                       22
<PAGE>   26
in the event that such rights or warrants are not so issued, the Purchase Price
shall be adjusted to be the Purchase Price which would then be in effect if such
record date had not been fixed.

                           (c) In the event that the Company shall fix a record
date for a distribution to all holders of Preferred Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of
indebtedness, cash (other than a regular periodic cash dividend at a rate not in
excess of 125% of the rate of the last cash dividend theretofore paid), assets,
stock (other than a dividend payable in Preferred Stock, but including any
dividend payable in stock other than Preferred Stock) or subscription rights or
warrants (excluding those referred to in Section 11(b) hereof), the Purchase
Price to be in effect after such record date shall be determined by multiplying
the Purchase Price in effect immediately prior to such record date by a
fraction, the numerator of which shall be the current market price (as
determined pursuant to Section 11(d) hereof) per share of Preferred Stock on
such record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes)
of the portion of the cash, assets or evidences of indebtedness so to be
distributed (in the case of regular periodic dividends at a rate in excess of
125% of the rate of the last cash dividend theretofore paid, only that portion
in excess of 125% of such rate) 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


                                       23
<PAGE>   27
         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 pay able in shares of such Common
         Stock or securities convertible into shares of such Common Stock
         (other than the Rights), or (B) any subdivision, combination or
         reclassification of such Common Stock, and the ex-dividend date for
         such dividend or distribution, or the record date for such subdivision,
         combination or reclassification shall not have occurred prior to the
         commencement of the requisite thirty (30) Trading Day or ten (10)
         Trading Day period, as set forth above, then, and in each such case,
         the "current market price" shall be properly adjusted to take into
         account ex-dividend trading. The closing price for each day shall be
         the last sale price, regular way, or, in case no such sale takes place
         on such day, the average of the closing bid and asked prices, regular
         way, in either case as reported in the principal consolidated
         transaction reporting system with respect to securities listed or
         admitted to trading on the New York Stock Exchange or, if 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


                                       24
<PAGE>   28
         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.

                           (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 200 (as such number may be appropriately adjusted for such events as
         stock splits, stock dividends and recapitalizations


                                       25
<PAGE>   29
         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 two-hundredth of a
         share of Preferred Stock shall be equal to the "current market price"
         of one share of Preferred Stock divided by 200.

                           (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; provided, further, however, that 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, and (ii) the Expiration Date. All calculations under this Section 11
shall be made to the nearest cent or to the nearest ten-thousandth of a share
of Common Stock or other share or one-millionth of a share of Preferred Stock,
as the case may be.

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


                                       26
<PAGE>   30
                           (g) All Rights originally issued by the Company
subsequent to any adjustment made to the Purchase Price hereunder shall evidence
the right to purchase, at the adjusted Purchase Price, the number of one
two-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 Sections 11(b) and (c), each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one two-hundredths of a share of Preferred Stock (calculated to the nearest
one-millionth) obtained by (i) multiplying (x) the number of one two-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 two-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 two-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,


                                       27
<PAGE>   31
upon each adjustment of the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Rights Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment. Rights Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein (and may bear, at the option of the Company, the adjusted Purchase
Price) and shall be registered in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.

                           (j) Irrespective of any adjustment or change in the
Purchase Price or the number of one two-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 two-hundredth of a share and the number of one two-hundredths of a share
which were expressed in the initial Rights Certificates issued hereunder.

                           (k) Before taking any action that would cause an
adjustment reducing the Purchase Price below the then stated value, if any, of
the number of one two-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 two-
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 two-hundredths of a share of Preferred Stock
and other capital stock or


                                       28
<PAGE>   32
securities of the Company, if any, issuable upon such exercise over and above
the number of one two-hundredths of a share of Preferred Stock and other capital
stock or securities of the Company, if any, issuable upon such exercise on the
basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such
additional shares (fractional or otherwise) or securities upon the occurrence of
the event requiring such adjustment.

                           (m) Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such reductions in the
Purchase Price, in addition to those adjustments expressly required by this
Section 11, as and to the extent that 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 stockholders.

                           (n) The Company covenants and agrees that it shall
not, at any time after the Distribution Date, (i) consolidate with any other
Person (other than a Subsidiary of the Company in a transaction which complies
with Section 11(o) hereof), (ii) merge with or into any other Person (other than
a Subsidiary of the Company in a transaction which complies with Section 11(o)
hereof), or (iii) sell or transfer (or permit any Subsidiary to sell or
transfer), in one transaction, or a series of related transactions, assets or
earning power aggregating more than 50% of the assets or earning power of the
Company and its Subsidiaries (taken as a whole) to any other Person or Persons
(other than the Company and/or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(o) hereof), if (x) at the
time of or immediately after such consolidation, merger or sale there are any
rights, warrants or other instruments or securities outstanding or agreements in
effect which would substantially diminish or


                                       29
<PAGE>   33
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 stockholders of the Person who constitutes, or would constitute,
the "Principal Party" for purposes of Section 13(a) hereof shall have received a
distribution of Rights previously owned by such Person or any of its Affiliates
and Associates.

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

                           (p) Anything in this Agreement to the contrary
notwithstanding, in the event that the Company shall at any time after the
Rights Dividend Declaration Date and prior to the Distribution Date (i) declare
a dividend on the outstanding shares of Common Stock 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 (including a description of any Rights which have become void as
a result thereof) and a brief statement of the facts accounting for such
adjustment, (b) promptly file with the Rights Agent, and with


                                       30
<PAGE>   34
each transfer agent for the Preferred Stock and the Common Stock, a copy of such
certificate, and (c) mail or cause the Rights Agent to 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 and
shall not be deemed to have knowledge of any adjustment unless and until the
Rights Agent shall have received such certificate.

                           Section 13. Consolidation, Merger or Sale or Transfer
of Assets or Earning Power.

                           (a) In the event that, following the Stock
Acquisition Date, 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 (except as may be contemplated by Section 13(d) hereof), proper
provision shall be made so that: (i) each holder of a Right, except as provided
in Section 7(e) hereof, shall thereafter have 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,
nonassessable and freely tradeable shares of Common Stock of the Princi-


                                       31
<PAGE>   35
pal Party (as such term is hereinafter defined), free and clear of 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 two-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 the Section 11(a)(ii) Event has occurred prior to the first occurrence of a
Section 13 Event, multiplying the number of such one two-hundredths of a share
for which a Right was exercisable immediately prior to the first occurrence of
the 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 Common Stock of such Principal Party on the date of consummation of such
Section 13 Event; (ii) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such Section 13 Event, all the obligations and duties
of the Company pursuant to this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of Section 11 hereof shall apply only to such
Principal Party following the first occurrence of a Section 13 Event; (iv) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of shares of its Common Stock) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof shall thereafter be applicable, as nearly as reasonably
may be, in relation to its shares of Common Stock thereafter deliverable upon
the exercise of the Rights; and (v) the provisions of Section 11(a)(ii) hereof
shall be of no effect following the first occurrence of any Section 13 Event.

                           (b) "Principal Party" shall mean

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


                                       32
<PAGE>   36
         ties are so issued, the Person that is the other party to such merger
         or consolidation; and

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

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding twelve (12)
month period registered under Section 12 of the Exchange Act, and such Person is
a direct or indirect Subsidiary of another Person the Common Stock of which is
and has been so registered, "Principal Party" shall refer to such other Person;
and (2) in case such Person is a Subsidiary, directly or indirectly, of more
than one Person, the Common 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 this Section 13 and unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing for the terms set forth in paragraphs (a) and
(b) of this Section 13 and further providing that, as soon as practicable after
the date of any consolidation, merger or sale of assets mentioned in paragraph
(a) of this Section 13, the Principal Party shall

                          (i) prepare and file a registration statement under
         the Securities 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


                                       33
<PAGE>   37
         all times meeting the requirements of the Securities 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 the 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).

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

                  Section 14. Fractional Rights and Fractional Shares.

                           (a) The Company shall not be required to issue
fractions of Rights, except prior to the Distribution Date as provided in
Section 11(p) hereof, or to distribute Rights Certificates which evidence
fractional Rights. In lieu of such fractional Rights, 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


                                       34
<PAGE>   38
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 market maker making
a market in the Rights selected by the Board of Directors of the Company. If on
any such date no such market maker is making a market in the Rights the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

                           (b) The Company shall not be required to issue
fractions of shares of Preferred Stock (other than fractions which are integral
multiples of one two-hundredth of a share of Preferred Stock (and then only to
the extent permissible under applicable law), which may, at the option of the
Company, be evidenced by depositary receipts) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one two-hundredth of a
share of Preferred Stock, and then only to the extent permissible under
applicable law). In lieu of fractional shares of Preferred Stock that are not
integral multiples of one two-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 two-hundredth


                                       35
<PAGE>   39
of a share of Preferred Stock. For purposes of this Section 14(b), the current
market value of one two-hundredth of a share of Preferred Stock shall be one
two-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 (1) share of
Common Stock shall be the closing price of one (1) 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


                                       36
<PAGE>   40
breach of this Agreement and shall be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.

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

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

                           (b) after the Distribution Date, the Rights
Certificates are transferable only on the registry books of the Rights Agent if
surrendered at the office of the Rights Agent designated for such 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 shall be required to be affected by any
notice to the contrary; and

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


                                       37
<PAGE>   41
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 two-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, suit, action 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


                                       38
<PAGE>   42
or transfer, power of attorney, endorsement, affidavit, letter, instruction,
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 or association into which the
Rights Agent or any successor Rights Agent may be merged or with which it may be
consolidated, or any corporation or association resulting from any merger or
consolidation to which the Rights Agent or any successor Rights Agent shall be a
party, or any corporation or association succeeding to the stock transfer
business of the Rights Agent or any successor Rights Agent, shall be the
successor to the Rights Agent under this Agreement without the execution or
filing of any paper or any further act on the part of any of the parties hereto;
provided, 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


                                       39
<PAGE>   43
cases such Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.

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

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

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

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

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


                                       40
<PAGE>   44
                           (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 (including any
adjustment which results in Rights becoming void) 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 receipt of a
certificate of any such adjustment delivered pursuant to Section 15 hereof or
actual knowledge of such voidance); 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 or other securities to be issued
pursuant to this Agreement or any Rights Certificate or as to whether any Common
Stock, Preferred Stock or other securities will, when so issued, be duly
authorized, validly 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 any one of the Chairman of the Board, the President, any Vice
President, the Secretary, any Assistant Secretary, the Treasurer or any
Assistant Treasurer of the Company and is authorized 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. Any application by the Rights
Agent for written instructions from the Company may, at the Rights Agent's
option set forth in writing any action proposed to be taken by, or


                                       41
<PAGE>   45
omission of, the Rights Agent under this Rights Agreement and the date on and/or
after which such action shall be taken or omission shall be effective. The
Rights Agent shall not be liable for any action taken by or omission of, the
Rights Agent in accordance with a proposal included in any such application on
or after the date specified in such application (which date shall not be less
than three Business Days after the date the Company actually receives such
application, unless the Company shall have consented in writing to an earlier
date) unless, prior to taking any such action (or the effective date in the case
of an omission), the Rights Agent shall have received written instructions in
response to such application specifying the action to be taken or omitted.

                           (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. The Rights Agent
shall not be under any duty or responsibility to insure compliance with any
applicable federal or state securities laws in connection with the issuance,
transfer or exchange of Rights.

                           (j) The Rights Agent shall promptly remit to the
Company any funds paid to it upon exercise of the Rights pursuant to Section 7
hereof. 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


                                       42
<PAGE>   46
for believing that repayment of such funds or adequate indemnification against
such risk or liability is not reasonably assured to it.

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

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Company, and to
each transfer agent of the Common Stock and Preferred Stock, by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) days' notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of the Common Stock
and Preferred Stock, by registered or certified mail, and to the holders of the
Rights Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of thirty (30) days after giving notice of such
removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a
Rights Certificate (who shall, with such notice, submit 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 corporation organized and doing business
under the laws of the United States, the State of New York, Connecticut or
Pennsylvania (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, Connecticut or Pennsylvania), in good standing, having a principal
office


                                       43
<PAGE>   47
in the State of New York, Connecticut or Pennsylvania, 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 either has
or is an affiliate of a corporation which has at the time of its appointment as
Rights Agent a combined capital and surplus of at least $50,000,000 and which
shall also meet any requirements imposed by the New York Stock Exchange on
transfer agents, depositaries and registrars. 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 the Board to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Rights Certificates
made in accordance with the provisions of this Agreement. In addition, in
connection with the issuance or sale of shares of Common Stock following the
Distribution Date and prior to the redemption or expiration of the Rights, the
Company (a) shall, with respect to shares of Common Stock so issued or sold
pursuant to the exercise of stock options or under any employee plan or
arrangement, granted or awarded as of the Distribution Date, or upon the
exercise, conversion or exchange of securities hereinafter issued by the
Company, and (b) may, in any other case, if deemed necessary or appropriate by
the Board of Directors of the Company, issue


                                       44
<PAGE>   48
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 the earlier of (i) the close of business on the
tenth Business Day following the Stock Acquisition Date, or (ii) the Final
Expiration Date, redeem all but not less than all the then outstanding Rights at
a redemption price of $.01 per Right, as such amount may be appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price"). Notwithstanding anything contained in
this Agreement to the contrary, the Rights shall not be exercisable after the
occurrence of the Section 11(a)(ii) Event until such time as the Company's right
of redemption hereunder has expired. The Company may, at its option, pay the
Redemption Price in cash, shares of Common Stock (based on the "current market
price," as defined in Section 11(d)(i) hereof, of the Common Stock at the time
of redemption) or any other form of consideration deemed appropriate by the
Board of Directors.

                           (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


                                       45
<PAGE>   49
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 periodic cash dividend out of
earnings or retained earnings of the Company at a rate not in excess of 125% of
the rate of the last periodic dividend theretofore paid), 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


                                       46
<PAGE>   50
notice shall be so given in the case of any action covered by clause (i) or (ii)
above at least twenty (20) days prior to the record date for determining holders
of the shares of Preferred Stock for purposes of such action, and in the case of
any such other action, at least twenty (20) days prior to the date of the taking
of such proposed action or the date of participation therein by the holders of
the shares of Preferred Stock whichever shall be the earlier.

                           (b) In case the Section 11(a)(ii) Event shall occur,
(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.

                  Section 25. Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Rights
Certificate to or on the Company shall be sufficiently given or made if sent by

such holder as shown on the registry books of the Company.

                  Section 26. Supplements and Amendments. Prior to the
Distribution Date and subject to the penultimate sentence of this Section 26,
the Company and the Rights Agent shall, if the Company so directs, supplement or
amend any provision of this Agreement without the approval of any holders of
certificates representing shares of Common Stock. From and after the
Distribution Date and subject to the penultimate sentence of this Section 26,
the Company and the Rights Agent shall, if the Company so directs, supplement or
amend this Agreement without the approval of any holders of Rights Certificates
in order (i) to cure any ambiguity, (ii) to correct or supplement any provision
contained herein which may be defective or inconsistent with any other
provisions herein, (iii) to shorten or lengthen any time period hereunder, or
(iv) to change or supplement the provisions hereunder in any manner which the
Company may deem necessary or desirable and which shall not adversely affect the
interests of the holders of Rights Certificates (other than an Acquiring Person
or an Affiliate or Associate of an Acquiring Person); provided, this Agreement
may not be supplemented or amended to lengthen, pursuant to clause (iii) of this
sentence, (A) a time period relating to when the Rights may be redeemed at such
time as the Rights are not then redeemable, or (B) any other time period unless
such lengthening is for the purpose of protecting, enhancing or clarifying the
rights of, and/or the benefits to, the holders of Rights. Upon the delivery of a
certificate from an appropriate officer of the Company which states that the
proposed supplement or amendment is in compliance with the terms of this Section
26, the Rights Agent shall execute such supplement or amendment. Notwithstanding
anything contained in this Agreement to the contrary, no supplement or amendment
shall


                                       48
<PAGE>   52
be made which changes the Redemption Price, the Final Expiration Date, the
Purchase Price or the number of one two-hundredths of a share of Preferred Stock
for which a Right is exercisable; provided, however, that at any time prior to
(i) a Stock Acquisition Date or (ii) 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 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 14d-2(a) of the General Rules and Regulations under the Exchange Act, if
upon consummation thereof, such Person would be the Beneficial Owner of 20% or
more of the shares of Common Stock then outstanding, the Board of Directors of
the Company may amend this Agreement to increase the Purchase Price or extend
the Final Expiration Date. Prior to the Distribution Date, the interests of the
holders of Rights shall be deemed coincident with the interests of the holders
of Common Stock.

                  Section 27. Successors. All the covenants and provisions of
this Agreement by or for the benefit of the Company or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

                  Section 28. Determinations and Actions by the Board of
Directors, etc. For all purposes of this Agreement, any calculation of the
number of shares of Common Stock outstanding at any particular time, including
for purposes of determining the particular percentage of such outstanding shares
of Common Stock of which any Person is the Beneficial Owner, shall be made in
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules
and Regulations under the Exchange Act. The Board of Directors of the Company
shall have the exclusive power and authority to administer this Agreement and to
exercise all rights and powers specifically granted to the Board or to the
Company, or as may be necessary or advisable in the administration of this
Agreement, including, without limitation, the right and power to (i) interpret
the provisions of this Agreement, and (ii) make all determinations deemed
necessary or advisable for the administration of this Agreement (including a
determination to redeem or not redeem the Rights or to amend the Agreement). All
such actions, calculations, interpretations and determinations


                                       49
<PAGE>   53
(including, for purposes of clause (y) below, all omissions with respect to the
foregoing) which are done or made by the Board in good faith, shall (x) be
final, conclusive and binding on the Company, the Rights Agent, the holders of
the Rights and all other parties, and (y) not subject the Board to any liability
to the holders of the Rights.

                  Section 29. Benefits of this Agreement. Nothing in this
Agreement shall be construed to give to any Person other than the Company, the
Rights Agent and the registered holders of the Rights Certificates (and, prior
to the Distribution Date, registered holders of the Common Stock) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock).

                  Section 30. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the close of business on the
tenth Business Day following the date of such determination by the Board of
Directors.

                  Section 31. Governing Law. This Agreement, each Right and each
Rights Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of Connecticut and for all purposes shall be governed by
and construed in accordance with the laws of such State applicable to contracts
made and to be performed entirely within such State.

                  Section 32. Counterparts. This Agreement may be executed in
any number of counterparts and each of such counterparts shall for all purposes
be deemed to be an original, and all such counterparts shall together
constitute but one and the same instrument.

                  Section 33. Descriptive Headings. Descriptive headings of the
several Sections of this Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

Agreement to be duly executed and their respective corporate seals to be
hereunto affixed and attested, all as of the day and year first above written.

registered assigns, is the registered owner of the number of Rights set forth

Connecticut corporation (the "Company"), and ChaseMellon Shareholder Services,
L.L.C., a limited liability corporation (the "Rights Agent"), to purchase from
the Company at any time after the Distribution Date (as such term is defined in
the Rights Agreement) and prior to the close of business on August 31, 2006 at
the office or offices of the Rights Agent designated for such purpose, or its
successors as Rights Agent, one two-hundredth of a fully paid, nonassessable
share of Series A Junior Participating Preferred Stock (the "Preferred Stock")
of the Company, at a purchase price of $90 per one two-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, at the election of the holder, in cash or shares
of Common 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 above, are the number and Purchase Price as of August 23, 1996
based on the shares of Preferred Stock as constituted at such date.

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

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

                  This Rights Certificate is subject to all of the terms,
provisions and conditions of the Rights Agreement,

which terms, provisions and conditions are hereby incorporated herein by
reference and made a part hereof and to which Rights Agreement reference is
hereby made for a full description of the rights, limitations of rights,
obligations, duties and immunities hereunder of the Rights Agent, the Company
and the holders of the Rights Certificates, which limitations of rights include
the temporary suspension of the exercisability of such Rights under the
specific circumstances set forth in the Rights Agreement. Copies of the Rights
Agreement are on file at the above-mentioned 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 office of the Rights Agent designated for
such purpose, with the forms of assignment and certificate on the reverse side
thereof duly executed, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of one two-hundredths of a share of Preferred
Stock as the Rights evidenced by the Rights Certificate or Rights Certificates
surrendered shall have entitled such holder to purchase. If this Rights
Certificate shall be exercised in part, the holder shall be entitled to receive
upon surrender hereof another Rights Certificate or Rights Certificates for
the number of whole Rights not exercised.

                  Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company at its option at a
redemption price of $.01 per Right at any time prior to the earlier of the close
of business on (i) the tenth business day following the Stock Acquisition Date
(as such time period may be extended pursuant to the Rights Agreement), and
(ii) the Final Expiration Date.

                  The Company is not required to issue fractional shares of
Preferred Stock upon the exercise of any Right or Rights evidenced hereby (other
than fractions which are integral multiples of one two-hundredth of a share of
Preferred Stock (and then only to the extent permissible under applicable law),
which may, at the election of the Company, be evidenced by depositary receipts),
but in lieu thereof a cash payment may be made, as provided in the Rights
Agreement.
