ITEM 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED

         On October 30, 1998, the Board of Directors of American Superconductor
Corporation (the "Company"), declared a dividend of one Right for each
outstanding share of the Company's Common Stock to stockholders of record at the
close of business on November 12, 1998 (the "Record Date"). Each Right entitles
the registered holder to purchase from the Company one share of Common Stock,
$.01 par value per share (the "Common Stock"), at a Purchase Price of $60.00 in
cash, subject to adjustment. The description and terms of the Rights are set
forth in a Rights Agreement dated as of October 30, 1998 (the "Rights
Agreement") between the Company and American Stock Transfer & Trust Company, as
Rights Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) 10 business days (or such
later date as may be determined by the Board of Directors of the Company)
following the later of (a) the first date of a public announcement that a person
or group of affiliated or associated persons (an "Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding shares of Common Stock or (b) the first date on which an
executive officer of the Company has actual knowledge that an Acquiring Person
has become such (the "Stock Acquisition Date"), or (ii) 10 business days (or
such later date as may be determined by the Board of Directors of the Company)
following the commencement of a tender offer or exchange offer that would result
in a person or group beneficially owning 15% or more of such outstanding shares
of Common Stock. Until the Distribution Date (or earlier redemption or
expiration of the rights), (i) the Rights will be evidenced by the Common Stock
certificates and will be transferred with and only with such Common Stock
certificates, (ii) new Common Stock certificates issued after the Record Date
will contain a notation incorporating the Rights Agreement by reference and
(iii) the surrender for transfer of any certificates for Common Stock
outstanding, even without such notation, will also constitute the transfer of
the Rights associated with the Common Stock represented by such certificate.

         The Rights are not exercisable until the Distribution Date and will
expire upon the earliest of the close of business on October 30, 2008 (the
"Final Expiration Date") unless earlier redeemed or exchanged as described
below. As soon as practicable after the Distribution Date, separate Rights
Certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, and except for shares of Common Stock issued upon the
exercise of stock options or under any employee plan or arrangement, or upon
the exercise, conversion or exchange of securities issued by the 


                                       -2-


   3


Company prior to the Distribution Date, only shares of Common Stock issued prior
to the Distribution Date will be issued with Rights.

         In the event that any Person becomes an Acquiring Person, unless the
event causing the 15% threshold to be crossed is a Permitted Offer (as defined
in the Rights Agreement), then, promptly following the first occurrence of such
event, each holder of a Right (except as provided below and in Section 7(e) of
the Rights Agreement) shall thereafter have the right to receive, upon exercise,
that number of shares of Common Stock of the Company (or, in certain
circumstances, cash, property or other securities of the Company) which equals
the exercise price of the Right divided by 50% of the current market price (as
defined in the Rights Agreement) per share of Common Stock at the date of the
occurrence of such event. However, Rights are not exercisable following such
event until such time as the Rights are no longer redeemable by the Company as
described below. Notwithstanding any of the foregoing, following the occurrence
of such event, all Rights that are, or (under certain circumstances specified in
the Rights Agreement) were, beneficially owned by any Acquiring Person will be
null and void. The event summarized in this paragraph is referred to as a
"Section 11(a)(ii) Event."

         For example, at an exercise price of $60.00 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following a Section
11(a)(ii) Event would entitle its holder to purchase for $60.00 such number of
shares of Common Stock (or other consideration, as noted above) as equals $60.00
divided by one-half of the current market price (as defined in the Rights
Agreement) of the Common Stock. Assuming that the Common Stock had a per share
value of $30.00 at such time, the holder of each valid Right would be entitled
to purchase four shares of Common Stock for $60.00.

         In the event that, at any time after any Person becomes an Acquiring
Person, (i) the Company is consolidated with, or merged with and into, another
entity and the Company is not the surviving entity of such consolidation or
merger (other than a consolidation or merger which follows a Permitted Offer) or
if the Company is the surviving entity, but shares of its outstanding Common
Stock are changed or exchanged for stock or securities (of any other person) or
cash or any other property, or (ii) 50% or more of the Company's assets or
earning power is sold or transferred, each holder of a Right (except Rights
which previously have been voided as set forth above) shall thereafter have the
right to receive, upon exercise, that number of shares of common stock of the
acquiring company which equals the exercise price of the Right divided by 50% of
the current market price of such common stock at the date of the occurrence of
the event. The events summarized in this paragraph are referred to as "Section
13 Events." A Section 11(a)(ii) Event and Section 13 Events are collectively
referred to as "Triggering Events."



                                       -3-

         For example, at an exercise price of $60.00 per Right, each valid Right
following a Section 13 Event would entitle its holder to purchase for $60.00
such number of shares of common stock of the acquiring company as equals $60.00
divided by one-half of the current market price (as defined in the Rights
Agreement) of such common stock. Assuming that such common stock had a per share
value of $20.00 at such time, the holder of each valid Right would be entitled
to purchase six shares of common stock of the acquiring company for $60.00.

         At any time after the occurrence of a Section 11(a)(ii) Event, subject
to certain conditions, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring Person which have become
void), in whole or in part, at an exchange ratio of one share of Common Stock
per Right (subject to adjustment).

         The Purchase Price payable, and the number of shares of Common Stock or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Common
Stock, (ii) if holders of the Common Stock are granted certain rights or
warrants to subscribe for Common Stock or convertible securities at less than
the then-current market price of the Common Stock, or (iii) upon the
distribution to holders of the Common Stock of evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings) or of subscription rights or warrants (other than those
referred to above). The number of Rights associated with each share of Common
Stock is also subject to adjustment in the event of a stock split of the Common
Stock or a stock dividend on the Common Stock payable in Common Stock or
subdivisions, consolidations or combinations of the Common Stock occurring, in
any such case, prior to the Distribution Date.

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

         At any time prior to the earlier of (i) the tenth Business Day (or such
later date as may be determined by the Board of Directors of the Company) after
the Stock Acquisition Date, or (ii) the Final Expiration Date, the Company may
redeem the Rights in whole, but not in part, at a price of $.001 per Right (the
"Redemption Price"), payable in cash or stock, provided, however, that if a
majority of the Board of Directors of the Company is comprised of persons
elected at a meeting of stockholders who were not nominated by the Board of
Directors in office immediately prior to such meeting, then the Rights may not
be redeemed for a period of 90 days after such election if such redemption is
reasonably likely to have


                                       -4-


   5


the purpose or effect of allowing any person to become an Acquiring Person or
otherwise facilitating the occurrence of a Triggering Event or a transaction
with an Acquiring Person. Immediately upon the action of the Board of Directors
ordering redemption of the Rights, the Rights will terminate and the only right
of the holders of Rights will be to receive the Redemption Price. The Rights may
also be redeemable following certain other circumstances specified in the Rights
Agreement.

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

         Subject to certain exceptions, any of the provisions of the Rights
Agreement may be amended by the Board of Directors of the Company prior to such
time as the Rights are no longer redeemable.

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to the Company's Current Report on Form 8-K
dated October 30, 1998. A copy of the Rights Agreement is available free of
charge from the Company. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.

                                RIGHTS AGREEMENT


         RIGHTS AGREEMENT, dated as of October 30, 1998 (the "Agreement"),
between American Superconductor Corporation, a Delaware corporation (the
"Company"), and American Stock Transfer & Trust Company, a New York corporation,
as Rights Agent (the "Rights Agent").


                               W I T N E S S E T H
                               - - - - - - - - - -

         WHEREAS, on October 30, 1998 the Board of Directors of the Company (the
"Board") authorized and declared a dividend distribution of one Right for each
share of Common Stock (as hereinafter defined) of the Company outstanding at the
close of business on November 12, 1998 (the "Record Date"), and authorized the
issuance of one Right (as such number may hereinafter be adjusted pursuant to
the provisions of Section 11(p) hereof) for each share of Common Stock of the
Company issued between the Record Date (whether originally issued or delivered
from the Company's treasury) and the earlier of the Distribution Date or the
Expiration Date, each Right initially representing the right to purchase one
share of Common Stock of the Company upon the terms and subject to the
conditions hereinafter set forth (the "Rights");

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

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

                  (a)      "Acquiring Person" shall mean any Person who or
which, together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the shares of Common Stock then outstanding,
but shall not include (i) the Company, (ii) any Subsidiary of the Company, (iii)
any employee benefit plan of the Company or of any Subsidiary of the Company, or
(iv) any Person organized, appointed or established by the Company for or
pursuant to the terms of any such plan. Notwithstanding the foregoing, no Person
shall become an "Acquiring Person" as the result of an acquisition of Common
Stock by the Company which, by reducing the number of shares outstanding,
increases the proportionate number of shares beneficially owned by such Person
to 15% or more of the shares of Common Stock of the Company then outstanding;
PROVIDED, HOWEVER, that if a Person shall become the Beneficial Owner of 15% or
more of the shares of Common Stock of the Company then outstanding by reason of
share purchases by the Company and shall, after such share purchases by the
Company, become the Beneficial Owner of any additional Common Stock of the
Company, then such Person shall be deemed to be an "Acquiring Person."
Notwithstanding the foregoing, if the Board determines in good faith that a
Person who would otherwise be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), has 





   5


become such inadvertently, and such Person divests as promptly as practicable a
sufficient number of shares of Common Stock so that such Person would no longer
be an "Acquiring Person," as defined pursuant to the foregoing provisions of
this paragraph (a), then such Person shall not be deemed to be an "Acquiring
Person" for any purposes of this Agreement unless and until such Person shall
again become an "Acquiring Person."

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

                  (c)      "Adjustment Shares" shall have the meaning set forth
in Section 11(a)(ii) hereof.

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

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

                  (i)      which such Person or any of such Person's Affiliates
         or Associates, directly or indirectly, has the right to acquire
         (whether such right is exercisable immediately or only after the
         passage of time) pursuant to any agreement, arrangement or
         understanding (other than customary agreements with and between
         underwriters and selling group members with respect to a bona fide
         public offering of securities), whether or not in writing, or upon the
         exercise of conversion rights, exchange rights, other rights, warrants
         or options, or otherwise; PROVIDED, HOWEVER, that a Person shall not be
         deemed the "Beneficial Owner" of, or to "beneficially own," (A)
         securities tendered pursuant to a tender or exchange offer made by such
         Person or any of such Person's Affiliates or Associates until such
         tendered securities are accepted for purchase or exchange, or (B)
         securities issuable upon exercise of Rights at any time prior to the
         occurrence of a Triggering Event, or (C) securities issuable upon
         exercise of Rights from and after the occurrence of a Triggering Event
         which Rights were acquired by such Person or any of such Person's
         Affiliates or Associates prior to the Distribution Date or pursuant to
         Section 3(a) or Section 22 hereof (the "Original Rights") or pursuant
         to Section 11(i) hereof in connection with an adjustment made with
         respect to any Original Rights;

                  (ii)     which such Person or any of such Person's Affiliates
         or Associates, directly or indirectly, has the right to vote or dispose
         of or has "beneficial ownership" of (as determined pursuant to Rule
         13d-3 of the General Rules and Regulations under the Exchange Act, or
         any comparable or successor rule), including pursuant to any agreement,
         arrangement or understanding (other than customary agreements with and
         between



                                        2

         public offering of securities), whether or not in writing; PROVIDED,
         HOWEVER, that a Person shall not be deemed the "Beneficial Owner" of,
         or to "beneficially own," any security under this subparagraph (ii) as
         a result of an agreement, arrangement or understanding to vote such
         security if such agreement, arrangement or understanding: (A) arises
         solely from a revocable proxy given in response to a public proxy or
         consent solicitation made pursuant to, and in accordance with, the
         applicable provisions of the General Rules and Regulations under the
         Exchange Act, and (B) is not then reportable by such Person on Schedule
         13D under the Exchange Act (or any comparable or successor report); or

                  (iii)    which are beneficially owned, directly or indirectly,
         by any other Person (or any Affiliate or Associate thereof) with which
         such Person (or any of such Person's Affiliates or Associates) has any
         agreement, arrangement or understanding (other than customary
         agreements with and between underwriters and selling group members with
         respect to a bona fide public offering of securities) whether or not in
         writing, for the purpose of acquiring, holding, voting (except pursuant
         to a revocable proxy as described in the proviso to subparagraph (ii)
         of this paragraph (d)) or disposing of any voting securities of the
         Company.

         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)(l)(i) of the General Rules
and Regulations under the Exchange Act.

                  (f)      "Business Day" shall mean any day other than a
Saturday, Sunday or a day on which banking institutions in the State of New York
are authorized or obligated by law or executive order to close.

                  (g)      "Close of business" on any given date shall mean 5:00
p.m., Massachusetts time, on such date; PROVIDED, HOWEVER, that if such date is
not a Business Day it shall mean 5:00 p.m., New York time, on the next
succeeding Business Day.

                  (h)      "Common Stock" shall mean the common stock, $.01 par
value, of the Company, except that "Common Stock" when used with reference to
any Person other than the Company shall mean the capital stock of such Person

         Section 3. ISSUANCE OF RIGHTS.

                  (a)      Until the earlier of (i) the close of business on the

the Stock Acquisition Date (or, if the tenth Business Day after the Stock

tender or exchange offer by any Person (other than the Company, any Subsidiary
of the Company, any employee benefit plan of the Company or of any Subsidiary of
the Company, or any Person 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 15% or more of the shares of Common Stock then outstanding,
in either instance other than pursuant to a Permitted Offer (the earlier of (i)
and (ii) being herein referred to as the "Distribution Date"), (x) the Rights
will be evidenced by the certificates for the Common Stock registered in the
names of the holders of the Common Stock (which certificates for Common Stock
shall be deemed also to be certificates for Rights) and not by separate
certificates, and (y) the Rights will be transferable only in connection with
the transfer



                                        6


   10


of the underlying shares of Common Stock (including a transfer to the Company).
As soon as practicable after the Distribution Date, the Rights Agent will send
by first-class, insured, postage prepaid mail, to each record holder of the
Common Stock as of the close of business on the Distribution Date, at the
address of such holder shown on the records of the Company, one or more rights
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 addition, in connection with the
issuance or sale of shares of Common Stock following the Distribution Date and
prior to the redemption or expiration of the Rights, the Company (a) shall, with
respect to shares of Common Stock so issued or sold pursuant to the exercise of
stock options or under any employee plan or arrangement, or upon the exercise,
conversion or exchange of securities issued by the Company prior to the
Distribution Date, and (b) may, in any other case, if deemed necessary or
appropriate by the Board, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale; PROVIDED, however,
that (i) no such Rights Certificate shall be issued if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax consequences to the Company or the
Person to whom such Rights Certificate would be issued, and (ii) no such Rights
Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof. In the event
that an adjustment in the number of Rights per share of Common Stock has been
made pursuant to Section 11(p) hereof, at the time of distribution of the Right
Certificates, the Company shall make the necessary and appropriate rounding
adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights. As of and after the Distribution Date,
the Rights will be evidenced solely by such Rights Certificates.

                  (b)      As promptly as practicable following the Record Date,
the Company will send a copy of a Summary of Rights to Purchase Common Stock, in
substantially the form attached hereto as EXHIBIT B, by first-class, postage
prepaid mail, to each record holder of the Common Stock as of the close of
business on the Record Date, at the address of such holder shown on the records
of the Company. With respect to certificates for the Common Stock outstanding as
of the close of business on the Record Date, until the Distribution Date, the
Rights will be evidenced by such certificates for the Common Stock and the
registered holders of the Common Stock shall also be the registered holders of
the associated Rights.

                  (c)      Rights shall be issued (i) in respect of all shares
of Common Stock that are issued (either as an original issuance or from the
Company's treasury) after the Record Date but prior to the earlier of the
Distribution Date or the Expiration Date and (ii) in connection with the
issuance or sale of Common Stock following the Distribution Date and prior to
the redemption or expiration of the Rights upon the




                                       7
   11


exercise of stock options or under any employee plan or arrangement, or upon the
exercise, conversion or exchange of securities granted or issued by the Company
prior to the Distribution Date. Certificates representing such shares of Common
Stock (including, without limitation, certificates issued upon transfer or
exchange of Common Stock) shall also be deemed to be certificates for Rights,
and shall bear the following legend:

                  This certificate also evidences and entitles the holder hereof
         to certain Rights as set forth in the Rights Agreement between American
         Superconductor Corporation (the "Company") and American Stock Transfer
         & Trust Company (the "Rights Agent") dated as of October 30, 1998, as
         the same may be amended, restated or renewed from time to time (the
         "Rights Agreement"), the terms of which are hereby incorporated herein
         by reference and a copy of which is on file at the principal office of
         the Company. Under certain circumstances, as set forth in the Rights
         Agreement, such Rights will be evidenced by separate certificates and
         will no longer be evidenced by this certificate. The Company will mail
         to the holder of this certificate a copy of the Rights Agreement, as in
         effect on the date of mailing, without charge, promptly after receipt
         of a written request therefor. Under certain circumstances set forth in
         the Rights Agreement, Rights issued to, or held by, any Person who is,
         was or becomes an Acquiring Person or any Affiliate or Associates
         thereof (as such terms are defined in the Rights Agreement), whether
         currently held by or on behalf of such Person or by any subsequent
         holder, may become null and void.

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

                  (d)      Until the earlier of the Distribution Date or the
Expiration Date, the transfer of any certificates representing shares of Common
Stock in respect of which Rights have been issued shall also constitute the
transfer of the Rights associated with such shares of Common Stock. In the event
that the Company purchases or acquires any shares of Common Stock after the
Record Date but prior to the Distribution Date, any Rights associated with such
shares of Common Stock shall be deemed cancelled and retired so that the Company
shall not be entitled to exercise any Rights associated with the shares of
Common Stock which are no longer outstanding.

         Section 4. FORM OF RIGHTS CERTIFICATES.

                  (a)      The Rights Certificates (and the forms of election to
purchase, certification and assignment to be printed on the reverse thereof)
shall each be substantially in the form set forth in EXHIBIT A hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or over-the-counter
market 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 entitle the holders thereof to
purchase such number of shares of Common Stock as shall be set forth therein at
the price set forth therein (such exercise price per share, the "Purchase
Price"), but the amount and type of securities purchasable upon the exercise of
each Right and the Purchase Price thereof shall be subject to adjustment as
provided herein.

                  (b)      Any Rights Certificate issued pursuant to Section 3,
Section 11(i) or Section 22 hereof that represents Rights beneficially owned by
persons known to be: (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
such Acquiring Person has any continuing agreement, arrangement or understanding
(whether or not in writing) regarding the transferred Rights or (B) a transfer
which the Board has determined is part of a plan, arrangement or understanding
(whether or not in writing) that has as a primary purpose or effect avoidance of
Section 7(e) hereof, and any Rights Certificate issued pursuant to Section 6 or
Section 11 hereof upon transfer, exchange, replacement or adjustment of any
other Rights Certificate referred to in this sentence, shall contain (to the
extent feasible) the following legend:

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

         The absence of the foregoing legend on any Rights Certificate shall in
no way affect any of the other provisions of this Agreement, including, without
limitation, the provisions of Section 7(e) hereof.

         Section 5. COUNTERSIGNATURE AND REGISTRATION.

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

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

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

                  (a)      Subject to the provisions of Section 4(b), Section
7(e) and Section 14 hereof, at any time after the close of business on the
Distribution Date, and at or prior to the close of business on the Expiration
Date, any Rights Certificate or Certificates (other than Rights Certificates
representing Rights that have become void pursuant to Section 7(e) hereof or
that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Rights Certificate or Certificates,
entitling the registered holder to purchase a like number of shares of Common
Stock (or, following a Triggering Event, Common Stock, other securities, cash or
other assets, as the case may be) as the Rights Certificate or 





                                       10
   14

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 form of assignment and certificate appropriately executed, at the
office of the Rights Agent designated for such purpose. Neither the Rights Agent
nor the Company shall be obligated to take any action whatsoever with respect to
the transfer of any such surrendered Rights Certificate until the registered
holder shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request. Thereupon the Rights Agent shall, subject to Section
4(b), Section 7(e) and Section 14 hereof, countersign and deliver to the Person
entitled thereto a Rights Certificate or Rights Certificates, as the case may
be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Rights Certificates.

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

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

                  (a)      Subject to Section 7(e) hereof, the registered holder
of any Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23
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 office of the Rights Agent designated for such purpose, together with
payment of the aggregate Purchase Price with respect to the total number of
shares of Common Stock (or other shares, securities, cash or other assets, as
the case may be) as to which such surrendered Rights are then exercisable, at or
prior to the earliest of (i) the Final Expiration Date, (ii) the time at which
the Rights expire as provided in Section 13(d) hereof, (iii) the time at which
the Rights are redeemed as provided in Section 23 hereof (the "Redemption Date")
or (iv) the time at



                                       11
   15

which such Rights are exchanged as provided in Section 24 hereof (the earliest
of (i), (ii), (iii) and (iv) being herein referred to as the "Expiration Date").

                  (b)      The Purchase Price for each share of Common Stock
pursuant to the exercise of a Right shall initially be $60.00 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 share of Common Stock (or other shares, securities,
cash or other assets, as the case may be) to be purchased as set forth below and
an amount equal to any applicable transfer tax, the Rights Agent shall, subject
to Section 20(k) hereof, thereupon promptly (i) (A) requisition from any
transfer agent of the shares of Common Stock (or make available, if the Rights
Agent is the transfer agent for such shares) certificates for the total number
of shares of Common Stock to be purchased and the Company hereby authorizes its
transfer agent to comply with such requests, or (B) if the Company shall have
elected to deposit the total number of shares of Common Stock issuable upon
exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing such number of shares of
Common Stock as are to be purchased (in which case certificates for the shares
of Common Stock represented by such receipts shall be deposited by the transfer
agent with the depositary agent) and the Company hereby directs the depositary
agent to comply with such requests, (ii) requisition from the Company the amount
of cash, if any, to be paid in lieu of fractional shares in accordance with
Section 14 hereof, (iii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder, and (iv) after receipt thereof, deliver such cash, if
any, to or upon the order of the registered holder of such Rights Certificate.
The payment of the Purchase Price (as such amount may be reduced pursuant to
Section 11(a)(iii) hereof) may be made in cash or by certified bank check or
money order payable to the order of the Company. In the event that the Company
is obligated to issue other securities of the Company, pay cash and/or
distribute other property pursuant to Section 11(a) hereof, the Company shall
make all arrangements necessary so that such other securities, cash and/or other
property are available for distribution by the Rights Agent, if and when
appropriate.

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



                                       12
   16

Rights Certificate, registered in such name or names as may be designated by
such holder, subject to the provisions of Section 14 hereof.

                  (e)      Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Section 11(a)(ii) Event, any
Rights beneficially owned by (i) an Acquiring Person or an Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee after the Acquiring
Person becomes such, or (iii) a transferee of an Acquiring Person (or of any
such Associate or Affiliate) who becomes a transferee prior to or concurrently
with the Acquiring Person becoming such and receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from the Acquiring
Person to holders of equity interests in such Acquiring Person or to any Person
with whom the Acquiring Person has any continuing agreement, arrangement or
understanding (whether or not in writing) regarding the transferred Rights or
(B) a transfer which the Board has determined is part of a plan, arrangement or
understanding (whether or not in writing) that has as a primary purpose or
effect avoidance of this Section 7(e), shall become null and void without any
further action and no holder of such Rights shall have any rights whatsoever
with respect to such Rights, whether under any provision of this Agreement or
otherwise. The Company shall use all reasonable efforts to insure that the
provisions of this Section 7(e) and Section 4(b) hereof are complied with, but
shall have no liability to any holder of Rights Certificates or other Person as
a result of its failure to make any determinations with respect to an Acquiring
Person or its Affiliates, Associates or transferees hereunder.

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

         Section 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement, and the Rights Agent shall so cancel and
retire, any other Rights Certificate purchased or acquired by the Company
otherwise than upon the exercise thereof. The Rights 




                                       13
   17
Agent shall deliver all cancelled Rights Certificates to the Company, or shall,
at the written request of the Company, destroy such cancelled Rights
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

         Section 9. RESERVATION AND AVAILABILITY OF CAPITAL STOCK.

                  (a)      The Company covenants and agrees that it will cause
to be reserved and kept available out of its authorized and unissued shares of
Common 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
Common 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 Common Stock (and, following
the occurrence of a Triggering Event, Common Stock and/or other securities)
issuable and deliverable upon the exercise of the Rights may be listed on any
national securities exchange or automated quotation system, 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 so listed upon official
notice of issuance upon such exercise.

                  (c)      The Company shall use its best efforts to (i) file,
as soon as practicable following the earliest date after the first occurrence of
a Section 11(a)(ii) Event on which the consideration to be delivered by the
Company upon exercise of the Rights has been determined in accordance with
Section 11(a)(iii) hereof, or as soon as is required by law following the
Distribution Date, as the case may be, a registration statement under the Act,
with respect to the securities purchasable upon exercise of the Rights on an
appropriate form, (ii) cause such registration statement to become effective as
soon as practicable after such filing, and (iii) cause such registration
statement to remain effective (with a prospectus at all times meeting the
requirements of the Act) until the earlier of (A) the date as of which the
Rights are no longer exercisable for such securities, and (B) the Expiration
Date. The Company 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 




                                       14
   18

unless the requisite registration or qualification in such jurisdiction shall
have been effected or obtained.

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

                  (e)      The Company further covenants and agrees that it will
pay when due and payable any and all federal and state transfer taxes and
charges that may be payable in respect of the issuance or delivery of the Rights
Certificates and of any certificates for shares of Common Stock (and/or other
securities) upon the exercise of Rights. The Company shall not, however, be
required (i) to pay any transfer tax that may be payable in respect of any
transfer or delivery of Rights Certificates to a Person other than, or the
issuance or delivery of shares of Common Stock (and/or other securities) in
respect of a name other than that of, the registered holder of the Rights
Certificate evidencing Rights surrendered for exercise or (ii) to issue or
deliver any certificates for shares of Common Stock (and/or other securities) 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. STOCK RECORD DATE. Each Person in whose name any
certificate for a number of shares of Common Stock (and/or other securities) 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 Common Stock (and/or
other securities) 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 Common Stock (and/or other securities) transfer
books of the Company are closed, such Person shall be deemed to have become the
record holder of such shares (fractional or otherwise) on, and such certificate
shall be dated, the next succeeding Business Day on which the Common Stock
(and/or other securities) transfer books of the Company are open. Prior to the
exercise of the Rights evidenced thereby, the holder of a Rights Certificate, as
such, shall not be entitled to any rights of a stockholder of the Company with
respect to securities for which the Rights shall be exercisable, including,
without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

   19
         Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR
NUMBER OF RIGHTS. The Purchase Price, the number and kind of shares covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

                  (a)(i)   In the event the Company shall at any time after the
         date of this Agreement (A) declare a dividend on the Common Stock
         payable in shares of Common Stock, (B) subdivide the outstanding Common
         Stock, (C) combine the outstanding Common Stock into a smaller number
         of shares, or (D) issue any shares of its capital stock in a
         reclassification of the Common Stock (including any such
         reclassification in connection with a consolidation or merger in which
         the Company is the continuing or surviving corporation), 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 Common 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 Common 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 Common 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; provided,
         however, that if the record date for any such dividend, subdivision,
         combination or reclassification shall occur prior to the Distribution
         Date, the Company shall make an appropriate adjustment to the Purchase
         Price (taking into account any additional Rights which may be issued as
         a result of such dividend, subdivision, combination or
         reclassification), in lieu of adjusting (as described above) the number
         of shares of Common Stock (or other capital stock, as the case may be)
         issuable upon exercise of the Rights and the foregoing provisions of
         this Section 11(a)(i) hereof shall not be applicable. If an event
         occurs that would require an adjustment under both this Section
         11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in
         this Section 11(a)(i) shall be in addition to, and shall be made prior
         to, any adjustment required pursuant to Section 11(a)(ii) hereof.

                  (ii)     Subject to Section 24 of this Agreement, in the event
         that any Person, alone or together with its Affiliates or Associates,
         becomes an Acquiring Person (other than pursuant to a Permitted Offer),
         then, promptly following the first 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 (subject to the last sentence of Section 23(a)), upon
         exercise thereof at the then current Purchase Price in 




                                       16
   20

         accordance with the terms of this Agreement, such number of shares of
         Common Stock of the Company that equals the result obtained by (x)
         multiplying the then current Purchase Price by the then number of
         shares of Common Stock for which a Right was exercisable immediately
         prior to the first occurrence of a Section 11(a)(ii) Event, and (y)
         dividing that product (which, following such first occurrence, shall
         thereafter be referred to as the "Purchase Price" for each Right and
         for all purposes of this Agreement) by 50% of the current market price
         (determined pursuant to Section 11(d) hereof) per share of Common Stock
         on the date of such first occurrence (such number of shares, the
         "Adjustment Shares").

                  (iii)    In the event that the number of shares of Common
         Stock that are authorized by the Company's 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, make adequate
         provision to substitute for the Adjustment Shares, upon payment of the
         applicable Purchase Price, (1) cash, (2) a reduction in the Purchase
         Price, (3) Common Stock or other equity securities of the Company
         (including, without limitation, shares, or units of shares, of
         preferred stock which the Board has deemed to have the same value as
         shares of Common Stock (such shares of preferred stock, "common stock
         equivalents")), (4) debt securities of the Company, (5) other assets,
         or (6) any combination of the foregoing, having an aggregate value
         equal to the Current Value, where such aggregate value has been
         determined by the Board based upon the advice of a nationally
         recognized investment banking firm selected by the Board; PROVIDED,
         HOWEVER, if the Company shall not have made adequate provision to
         deliver value pursuant to clause (B) above within thirty (30) days
         following the later of (x) the first occurrence of a Section 11(a)(ii)
         Event and (y) the date on which the Company's right of redemption
         pursuant to Section 23(a) expires (the later of (x) and (y) being
         referred to herein as the "Section 11(a)(ii) Trigger Date"), then the
         Company shall be obligated to deliver, upon the surrender for exercise
         of a Right and without requiring payment of the Purchase Price, shares
         of Common Stock (to the extent available) and then, if necessary, cash,
         which shares and/or cash have an aggregate value equal to the Spread.
         If the Board shall determine in good faith that it is likely that
         sufficient additional shares of Common Stock could be authorized for
         issuance upon exercise in full of the Rights, the thirty (30) day
         period set forth above may be extended to the extent necessary, but not
         more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in
         order that the Company may seek shareholder approval for the
         authorization of such additional shares (such period, as it may be
         extended,




                                       17
   21
         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
         the Common Stock shall be the current market price (as determined
         pursuant to Section 11(d) hereof) per share of the Common Stock on the
         Section 11(a)(ii) Trigger Date and the value of any "common stock
         equivalent" shall be deemed to have the same value as the Common Stock
         on such date.

                  (b)      In case the Company shall fix a record date for the
issuance of rights (other than the Rights), options or warrants to all holders
of Common Stock entitling them to subscribe for or purchase (for a period
expiring within forty-five (45) calendar days after such record date) Common
Stock (or common stock equivalents) or securities convertible into Common Stock
or common stock equivalents at a price per share of Common Stock or per share of
common stock equivalent (or having a conversion price per share, if a security
convertible into Common Stock or common stock equivalent) less than the current
market price (as determined pursuant to Section 11(d) hereof) per share of
Common 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 Common Stock outstanding on such record date,
plus the number of shares of Common Stock which the aggregate offering price of
the total number of shares of Common Stock and/or common stock equivalents 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 Common Stock
outstanding on such record date, plus the number of additional shares of Common
Stock and/or common stock equivalents to be offered for subscription or purchase
(or into which the convertible securities so to be offered are initially
convertible). In case such subscription price may be paid by delivery of
consideration part or all of which may be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes. Shares of 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




                                       18
   22
date is fixed, and in the event that such rights, options or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

                  (c)      In case the Company shall fix a record date for a
distribution to all holders of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash (other than a regular
quarterly cash dividend out of the earnings or retained earnings of the
Company), assets (other than a dividend payable in Common Stock, but including
any dividend payable in stock other than Common 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 Common Stock on such
record date, less the fair market value (as determined in good faith by the
Board, whose determination shall be described in a statement filed with the
Rights Agent and shall be conclusive for all purposes) of the portion of the
cash, assets or evidences of indebtedness so to be distributed or of such
subscription rights or warrants applicable to a share of Common Stock and the
denominator of which shall be such current market price (as determined pursuant
to Section 11(d) hereof) per share of Common Stock on such record date. 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)      For the purpose of any computation hereunder, other
than computations made pursuant to Section 11(a)(iii) hereof, the "current
market price" per share of Common Stock on any date shall be deemed to be the
average of the daily closing prices per share of such Common Stock for the
thirty (30) consecutive Trading Days (as such term is hereinafter defined)
immediately prior to such date, and for purposes of computations made pursuant
to Section 11(a)(iii) hereof, the "current market price" per share of Common
Stock on any date shall be deemed to be the average of the daily closing prices
per share of such Common Stock for the ten (10) consecutive Trading Days
immediately following such date; PROVIDED, HOWEVER, that in the event that the
current market price per share of the Common Stock is determined during a period
following the announcement by the issuer of such Common Stock of (A) a dividend
or distribution on such Common Stock payable in shares of such Common Stock or
securities convertible into shares of such Common Stock (other than the Rights),
or (B) any subdivision, combination or reclassification of such Common Stock,
and 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 expiration 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 




                                       19
   23

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 principal national securities exchange on
which the shares of Common Stock are listed or admitted to trading or, if the
shares of Common Stock are not listed or admitted to trading on any national
securities exchange, the last quoted price or, if not so quoted, the average of
the high bid and the low asked prices in the over-the-counter market, as
reported by The Nasdaq Stock Market, Inc. ("Nasdaq") or such other system then
in use, or, if on any such date the shares of Common Stock are not quoted by any
such organization, the average of the closing bid and asked prices as furnished
by a professional market maker making a market in the Common Stock selected by
the Board. If on any such date no market maker is making a market in the Common
Stock, the fair value of such shares on such date as determined in good faith by
the Board shall be used. The term "Trading Day" shall mean a day on which Nasdaq
or any 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 Nasdaq or 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, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

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

                  (f)      If as a result of an adjustment made pursuant to
Section 11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter
exercised shall become entitled to receive any securities other than Common
Stock, thereafter the number of such other securities 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 Common Stock contained in
Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the
provisions




                                       20
   24

of Sections 7, 9, 10, 13 and 14 hereof with respect to the Common Stock shall
apply on like terms to any such other securities; PROVIDED, HOWEVER, that the
Company shall not be liable for its inability to reserve and keep available for
issuance upon exercise of the Rights pursuant to Section 11(a)(ii) a number of
shares of Common Stock greater than the number then authorized by the Company's
Certificate of Incorporation but not outstanding or reserved for other purposes.

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




                                       21
   25

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 shares of Common Stock issuable upon the
exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per share and the number of
shares 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 shares of Common 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 shares of
fully paid and nonassessable Common 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 shares of Common Stock and other capital stock or securities
of the Company, if any, issuable upon such exercise over and above the shares of
Common 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
shall determine to be advisable in order that any (i) consolidation or
subdivision of the Common Stock, (ii) issuance wholly for cash of any shares of
Common Stock at less than the current market price, (iii) issuance wholly for
cash of shares of Common Stock or securities which by their terms are
convertible into or exchangeable for shares of Common Stock, (iv) stock
dividends or (v) issuance of rights, options or warrants referred to in this
Section 11, hereafter




                                       22
   26

made by the Company to holders of its Common 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 that 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 that would substantially diminish or otherwise eliminate the benefits
intended to be afforded by the Rights or (y) prior to, simultaneously with or
immediately after such consolidation, merger or sale, the shareholders of the
Person who constitutes, or would constitute, the "Principal Party" for purposes
of Section 13(a) hereof shall have received a distribution of Rights previously
owned by such Person or any of its Affiliates and Associates. The Company shall
not consummate any such consolidation, merger, sale or transfer unless prior
thereto the Company and such other Person shall have executed and delivered to
the Rights Agent a supplemental agreement evidencing compliance with this
Section 11(n).

                  (o)      The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Section 23, Section 24 or
Section 27 hereof, take (or permit any Subsidiary 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
Record Date and prior to the Distribution Date (i) declare or pay any 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 number of shares of Common Stock outstanding immediately
prior to the occurrence of such event and the denominator of which 




                                       23
   27

shall be the 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 or Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Common Stock, a copy of such certificate, and (c) mail a brief summary thereof
to each holder of a Rights Certificate (or, if prior to the Distribution Date,
to each holder of a certificate representing shares of Common Stock) in
accordance with Section 26 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 it
shall have received such certificate.

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

                  (a)      In the event that, at any time after a Person has
become an Acquiring Person, (x) the Company shall consolidate with, or merge
with and into, any other Person (other than a Subsidiary of the Company in a
transaction that complies with Section 11(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 that
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 and except as
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, non-assessable and freely
tradeable shares of Common Stock of the Principal Party (as such term is
hereinafter defined), not subject to any liens, encumbrances, rights of first
refusal or other adverse claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the number of shares of Common
Stock for which a Right is exercisable immediately prior to the 





                                       24
   28

first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has
occurred prior to the first occurrence of a Section 13 Event, multiplying the
number of such shares for which a Right was exercisable immediately prior to the
first occurrence of a Section 11(a)(ii) Event by the Purchase Price in effect
immediately prior to such first occurrence), and (2) dividing that product
(which, following the first occurrence of a Section 13 Event, shall be referred
to as the "Purchase Price" for each Right and for all purposes of this
Agreement) by 50% of the current market price (determined pursuant to Section
11(d)(i) hereof) per share of the Common Stock of such Principal Party on the
date of consummation of such Section 13 Event; (ii) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such Section 13 Event,
all the obligations and duties of the Company pursuant to this Agreement; (iii)
the term "Company" shall thereafter be deemed to refer to such Principal Party,
it being specifically intended that, subject to clause (v) below, 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
         securities are so issued, the Person that is the other party to such
         merger or consolidation; and

                           (ii)     in the case of any transaction described in
         clause (z) of the first sentence of Section 13(a), 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;
(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; and (3)
in case such Person is owned, directly or




                                       25
   29

indirectly, by a joint venture formed by two or more Persons that are not owned,
directly or indirectly, by the same Person, the rules set forth in (1) and (2)
above shall apply to each of the chains of ownership having an interest in such
joint venture as if such party were a "Subsidiary" of both or all of such joint
ventures and the Principal Parties in each such chain shall bear the obligations
set forth in this Section 13 in the same ratio as their direct or indirect
interests in such Person bear to the total of such interests.

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

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

                           (ii)     use its best efforts to qualify or register
         the Rights and the securities purchasable upon exercise of the Rights
         under the blue sky laws of such jurisdictions as may be necessary or
         appropriate; and

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

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

                  (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 (or a wholly owned Subsidiary of any such
Person or Persons) who acquired shares 




                                       26
   30
of Common Stock pursuant to a Permitted Offer, (ii) the price per share of
Common Stock paid 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 Permitted Offer, and (iii) the form of consideration
paid in such transaction is the same as the form of consideration paid pursuant
to such Permitted 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(i) or
11(p) hereof, or to distribute Rights Certificates that evidence fractional
Rights. In lieu of such fractional Rights, there shall be paid to the registered
holders of the Rights Certificates with regard to which such fractional Rights
would otherwise be issuable, an amount in cash equal to the same fraction of the
current market value of a whole Right. For purposes of this Section 14(a), the
current market value of a whole Right shall be the closing price of the Rights
for the Trading Day immediately prior to the date on which such fractional
Rights would have been otherwise issuable. The closing price of the Rights for
any day shall be the last sale price, regular way, or, in case no such sale
takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the 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 the low asked prices in the
over-the-counter market, as reported by Nasdaq or such other system then in use
or, if on any such date the Rights are not quoted by any such organization, the
average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Rights selected by the Board. If on any such
date no such market maker is making a market in the Rights, the fair value of
the Rights on such date as determined in good faith by the Board shall be used.

                  (b)      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 shall pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market price of one (1) share of Common Stock (as
determined pursuant to Section 11(d) hereof) for the Trading Day immediately
prior to the date of such exercise.

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

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

                  (a)      prior to the 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 duly completed and fully executed;

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



                                       28
   32
                  (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, the Company must use its best
efforts to prevent the issuance of any such order, decree or ruling and 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 shares of Common Stock
or any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Rights Certificate be construed to confer upon the holder of any
Rights Certificate, as such, any of the rights of a stockholder of the Company
or any right to vote for the election of directors or upon any matter submitted
to stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Rights Certificate shall have been exercised in accordance with the
provisions hereof.

         Section 18. CONCERNING THE RIGHTS AGENT.

                  (a)      The Company agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from time
to time, on demand of the Rights Agent, its reasonable expenses and counsel fees
and disbursements and other disbursements incurred in the administration and
execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability or expense, incurred without gross
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




                                       29
   33
or transfer, power of attorney, endorsement, affidavit, letter, notice,
direction, consent, certificate, statement, or other paper or document believed
by it to be genuine and to be signed, executed and, where necessary, verified or
acknowledged, by the proper Person or Persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

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

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

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

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

                  (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 




                                       30
   34
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 gross negligence, bad faith or willful misconduct.

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

                  (e)      The Rights Agent shall not be under any
responsibility in respect of the validity of this Agreement or the execution and
delivery hereof (except the due execution hereof by the Rights Agent) or in
respect of the validity or execution of any Rights Certificate (except its
countersignature thereof); nor shall it be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any
Rights Certificate; nor shall it be responsible for any adjustment required
under the provisions of Section 11, Section 13 or Section 24 hereof or
responsible for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such adjustment
(except with respect to the exercise of Rights evidenced by Rights Certificates
after receipt of a certificate describing any such adjustment, delivered
pursuant to Section 12); 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 other securities to be issued pursuant to this Agreement or
any Rights Certificate or as to whether any shares of Common Stock or other
securities will, when so issued, be validly authorized and issued, fully paid
and nonassessable.

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





                                       31
   35


further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Agreement.

                  (g)      The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
the Chairman of the Board, the President, any Vice President, the Secretary, any
Assistant Secretary, the Treasurer or any Assistant Treasurer of the Company,
and to apply to such officers for advice or instructions in connection with its
duties, and it shall not be liable for any action taken or suffered to be taken
by it in good faith in accordance with instructions of any such officer. Any
application by the Rights Agent for written instructions from the Company may,
at the option of the Rights Agent, set forth in writing any action proposed to
be taken or omitted by the Rights Agent with respect to its duties or
obligations under this Rights Agreement and the date on and/or after which such
action shall be taken or omitted and the Rights Agent shall not be liable for
any action taken or omitted in accordance with a proposal included in any such
application on or after the date specified therein (which date shall not be less
than five Business Days after the date any such officer actually receives such
application, unless any such officer shall have consented in writing to an
earlier date) unless, prior to taking or omitting any such action, the Rights
Agent has 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.

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




                                       32
   36
                  (k)      If, with respect to any Rights Certificate
surrendered to the Rights Agent for exercise or transfer, the certificate
attached to the form of assignment or form of election to purchase, as the case
may be, has not been completed, the Company and the Rights Agent will deem the
beneficial owner of the rights evidenced by such Rights Certificate to be an
Acquiring Person or an Affiliate or Associate thereof and such assignment or
election to purchase will not be honored.

         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, 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, by registered or certified
mail, and to the holders of the Rights Certificates by first-class mail. If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of thirty (30) days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then any registered holder of
any Rights Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court, shall be (a) a corporation organized and
doing business under the laws of the United States (or of any state of the
United States) in good standing, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject to supervision or
examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least
$50,000,000 or (b) an affiliate of a corporation described in clause (a) of this
sentence. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Stock,
and 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.




                                       33
   37
         Section 22. ISSUANCE OF NEW RIGHTS CERTIFICATES. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by its Board 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.

         Section 23. REDEMPTION AND TERMINATION.

                  (a)      The Board may, at its option, at any time prior to
the earlier of (i) the close of business on the tenth Business Day (or such
later date as may be determined by the Board pursuant to clause (i) of the first
sentence of Section 3(a) with respect to the Distribution Date) following the
Stock Acquisition Date (or, if the Stock Acquisition Date shall have occurred
prior to the Record Date, the close of business on the tenth Business Day
following the Record Date) or (ii) the Final Expiration Date, redeem all but not
less than all the then outstanding Rights at a redemption price of $.001 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"). The
redemption of the Rights by the Board may be made effective at such time, on
such basis and with such conditions as the Board in its sole discretion may
establish. 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, or any combination of any of the foregoing, deemed
appropriate by the Board. Notwithstanding anything contained in this Agreement
to the contrary, the Rights shall not be exercisable after the first occurrence
of a Section 11(a)(ii) Event until such time as the Company's right of
redemption hereunder has expired.

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





                                       34
   38

                  (c)      Notwithstanding the provisions of Section 23(a)
hereof, in the event that a majority of the Board is elected by shareholder
action by written consent, or is comprised of persons elected at a meeting of
stockholders who were not nominated by the Board in office immediately prior to
such meeting, then for a period of ninety (90) days following the effectiveness
of such election, the Rights shall not be redeemed if such redemption is
reasonably likely to have the purpose or effect of allowing any Person to become
an Acquiring Person or otherwise facilitating the occurrence of a Triggering
Event or a transaction with an Acquiring Person.

                  (d)      The Company may, at its option, discharge all of its
obligations with respect to the Rights by (i) issuing a press release announcing
the manner of redemption of the Rights in accordance with this Agreement and
(ii) mailing payment of the Redemption Price to the registered holders of the
Rights at their last addresses as they appear on the registry books of the
Rights Agent or, prior to the Distribution Date, on the registry books of the
Transfer Agent of the Common Shares, and upon such action, all outstanding
Rights and Right Certificates shall be null and void without any further action
by the Company.

         Section 24. EXCHANGE.

                  (a)      The Board may, at its option, at any time after the
occurrence of a Section 11(a)(ii) Event, exchange all or part of the then
outstanding and exercisable Rights (which (i) shall not include Rights that have
become void pursuant to the provisions of Section 7(e) hereof, and (ii) shall
include, without limitation, any Rights issued after the Distribution Date) for
shares of Common Stock at an exchange ratio of one share of Common Stock per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Stock for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the shares of Common Stock then outstanding.

                  (b)      Immediately upon the action of the Board ordering the
exchange of any Rights pursuant to subsection (a) of this Section 24, evidence
of which shall have been filed with the Rights Agent, and without any further
action and without any notice, the right to exercise such Rights shall terminate
and the only right thereafter of a holder of such Rights shall be to receive
that number of shares of Common Stock equal to the number of such Rights held by
such holder multiplied by the Exchange Ratio. The Company shall promptly give
public notice of any such exchange; PROVIDED, HOWEVER, that the failure to give,
or any defect in, such notice shall not affect the validity of such exchange.
The Company promptly shall mail a 




                                       35
   39

notice of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange shall state the
method by which the exchange of shares of Common Stock for Rights will be
effected and, in the event of any partial exchange, the number of Rights which
will be exchanged. Any partial exchange shall be effected pro rata based on the
number of Rights (other than Rights which have become void pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights.

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

                  (d)      The Company shall not be required to issue fractions
of shares of Common Stock or to distribute certificates which evidence
fractional shares of Common Stock. In lieu of such fractional shares of Common
Stock, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional shares of Common Stock would otherwise be
issuable, an amount in cash equal to the same fraction of the current market
value of a whole share of Common Stock. For the purposes of this subsection (e),
the current market value of a whole share of Common Stock shall be the closing
price per share of Common Stock (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

         Section 25. NOTICE OF CERTAIN EVENTS.

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




                                       36
   40



Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of
the Company, then, in each such case, the Company shall give to each holder of a
Rights Certificate, to the extent feasible and in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, distribution of rights or warrants, or
the date on which such reclassification, consolidation, merger, sale, transfer,
liquidation, dissolution, or winding up is to take place and the date of
participation therein by the holders of the shares of Common Stock, if any such
date is to be fixed, and such notice shall be so given in the case of any action
covered by clause (i) or (ii) above at least twenty (20) days prior to the
record date for determining holders of the shares of Common 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 Common Stock, whichever
shall be the earlier.

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

         Section 26. 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 first-class
mail, postage prepaid, addressed (until another address is filed in writing with
the Rights Agent) as follows:

                                       37
   41


Certificate to or on the Rights Agent shall be sufficiently given or made if
sent by first-class mail, postage prepaid, addressed (until another address is
filed in writing with the Company) as follows:


                     American Stock Transfer & Trust Company
                                 40 Wall Street
                               New York, NY 10005

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Rights Certificate (or, if
prior to the Distribution Date, to the holder of certificates representing
shares of Common Stock) shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Company.

         Section 27. SUPPLEMENTS AND AMENDMENTS. Except as provided in the
penultimate sentence of this Section 27, for so long as the Rights are then
redeemable, the Company may, in its sole and absolute discretion, and the Rights
Agent shall, if the Company so directs, supplement or amend any provision of
this Agreement in any respect without the approval of any holders of the Rights.
At any time when the Rights are no longer redeemable, except as provided in the
penultimate sentence of this Section 27, the Company may, by approval of a
majority of the members of the Board (provided, that at the time of such
approval of the Board there are then in office not less than two Continuing
Directors and such supplement or amendment is approved by a majority of the
Continuing Directors then in office), and the Rights Agent shall, if the Company
so directs, supplement or amend this Agreement without the approval of any
holders of Rights in order (i) to cure any ambiguity or (ii) to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, PROVIDED that no such supplement or amendment
shall adversely affect the interests of the holders of Rights as such (other
than an Acquiring Person or an Affiliate or Associate of an Acquiring Person).
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 27, the Rights Agent shall execute such supplement or
amendment. Notwithstanding anything contained in this Agreement to the contrary,
no supplement or amendment shall be made which changes the Redemption Price.
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 28. 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 29. ACTIONS BY THE BOARD, ETC. The Board 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 this Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights and all other parties, and (y) not
subject the Board to any liability to the holders of the Rights.

         Section 30. BENEFITS OF THIS AGREEMENT. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the 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 31. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board determines
in its good faith judgment that severing the invalid, void or unenforceable
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 day
following the date of such determination by the Board.

         Section 32. GOVERNING LAW. This Agreement, each Right and each Rights
Certificate issued hereunder shall be deemed to be a contract made under the

         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,

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

                              SUMMARY OF RIGHTS TO
                              PURCHASE COMMON STOCK

         On October 30, 1998, the Board of Directors of American Superconductor
Corporation (the "Company"), declared a dividend of one Right for each
outstanding share of the Company's Common Stock to stockholders of record at the
close of business on November 12, 1998 (the "Record Date"). Each Right entitles
the registered holder to purchase from the Company one share of Common Stock,
$.01 par value per share (the "Common Stock"), at a Purchase Price of $60.00 in
cash, subject to adjustment. The description and terms of the Rights are set
forth in a Rights Agreement dated as of October 30, 1998 (the "Rights
Agreement") between the Company and American Stock Transfer & Trust Company, as
Rights Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) 10 business days (or such
later date as may be determined by the Board of Directors of the Company)
following the later of (a) the first date of a public announcement that a person
or group of affiliated or associated persons (an "Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding shares of Common Stock or (b) the first date on which an
executive officer of the Company has actual knowledge that an Acquiring Person
has become such (the "Stock Acquisition Date"), or (ii) 10 business days (or
such later date as may be determined by the Board of Directors of the Company)
following the commencement of a tender offer or exchange offer that would result
in a person or group beneficially owning 15% or more of such outstanding shares
of Common Stock. Until the Distribution Date (or earlier redemption or
expiration of the rights), (i) the Rights will be evidenced by the Common Stock
certificates and will be transferred with and only with such Common Stock
certificates, (ii) new Common Stock certificates issued after the Record Date
will contain a notation incorporating the Rights Agreement by reference and
(iii) the surrender for transfer of any certificates for Common Stock
outstanding, even without such notation, will also constitute the transfer of
the Rights associated with the Common Stock represented by such certificate.

         The Rights are not exercisable until the Distribution Date and will
expire upon the earliest of the close of business on October 30, 2008 (the
"Final Expiration Date") unless earlier redeemed or exchanged as described
below. As soon as practicable after the Distribution Date, separate Rights
Certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and,



                                       B-1


   53



thereafter, the separate Rights Certificates alone will represent the Rights.
Except as otherwise determined by the Board of Directors, and except for shares
of Common Stock issued upon the exercise of stock options or under any employee
plan or arrangement, or upon the exercise, conversion or exchange of securities
issued by the Company prior to the Distribution Date, only shares of Common
Stock issued prior to the Distribution Date will be issued with Rights.

         In the event that any Person becomes an Acquiring Person, unless the
event causing the 15% threshold to be crossed is a Permitted Offer (as defined
in the Rights Agreement), then, promptly following the first occurrence of such
event, each holder of a Right (except as provided below and in Section 7(e) of
the Rights Agreement) shall thereafter have the right to receive, upon exercise,
that number of shares of Common Stock of the Company (or, in certain
circumstances, cash, property or other securities of the Company) which equals
the exercise price of the Right divided by 50% of the current market price (as
defined in the Rights Agreement) per share of Common Stock at the date of the
occurrence of such event. However, Rights are not exercisable following such
event until such time as the Rights are no longer redeemable by the Company as
described below. Notwithstanding any of the foregoing, following the occurrence
of such event, all Rights that are, or (under certain circumstances specified in
the Rights Agreement) were, beneficially owned by any Acquiring Person will be
null and void. The event summarized in this paragraph is referred to as a
"Section 11(a)(ii) Event."

         For example, at an exercise price of $60.00 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following a Section
11(a)(ii) Event would entitle its holder to purchase for $60.00 such number of
shares of Common Stock (or other consideration, as noted above) as equals $60.00
divided by one-half of the current market price (as defined in the Rights
Agreement) of the Common Stock. Assuming that the Common Stock had a per share
value of $30.00 at such time, the holder of each valid Right would be entitled
to purchase four shares of Common Stock for $60.00.

         In the event that, at any time after any Person becomes an Acquiring
Person, (i) the Company is consolidated with, or merged with and into, another
entity and the Company is not the surviving entity of such consolidation or
merger (other than a consolidation or merger which follows a Permitted Offer) or
if the Company is the surviving entity, but shares of its outstanding Common
Stock are changed or exchanged for stock or securities (of any other person) or
cash or any other property, or (ii) 50% or more of the Company's assets or
earning power is sold or transferred, each holder of a Right (except Rights
which previously have been voided as set forth above) shall thereafter have the
right to receive, upon exercise, that number of shares of common stock of the
acquiring company which equals the exercise price of the Right divided by 50% of
the current market price of such common stock at the date of the occurrence of
the event. The events summarized in this paragraph are referred



                                       B-2

to as "Section 13 Events." A Section 11(a)(ii) Event and Section 13 Events are
collectively referred to as "Triggering Events."

         For example, at an exercise price of $60.00 per Right, each valid Right
following a Section 13 Event would entitle its holder to purchase for $60.00
such number of shares of common stock of the acquiring company as equals $60.00
divided by one-half of the current market price (as defined in the Rights
Agreement) of such common stock. Assuming that such common stock had a per share
value of $20.00 at such time, the holder of each valid Right would be entitled
to purchase six shares of common stock of the acquiring company for $60.00.

         At any time after the occurrence of a Section 11(a)(ii) Event, subject
to certain conditions, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring Person which have become
void), in whole or in part, at an exchange ratio of one share of Common Stock
per Right (subject to adjustment).

         The Purchase Price payable, and the number of shares of Common Stock or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Common
Stock, (ii) if holders of the Common Stock are granted certain rights or
warrants to subscribe for Common Stock or convertible securities at less than
the then-current market price of the Common Stock, or (iii) upon the
distribution to holders of the Common Stock of evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings) or of subscription rights or warrants (other than those
referred to above). The number of Rights associated with each share of Common
Stock is also subject to adjustment in the event of a stock split of the Common
Stock or a stock dividend on the Common Stock payable in Common Stock or
subdivisions, consolidations or combinations of the Common Stock occurring, in
any such case, prior to the Distribution Date.

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

         At any time prior to the earlier of (i) the tenth Business Day (or such
later date as may be determined by the Board of Directors of the Company) after
the Stock Acquisition Date, or (ii) the Final Expiration Date, the Company may
redeem the Rights in whole, but not in part, at a price of $.001 per Right (the
"Redemption Price"), payable in cash or stock, provided, however, that if a
majority of the Board of Directors of the Company is comprised of persons
elected at a meeting of




                                      B-3
   55

stockholders who were not nominated by the Board of Directors in office
immediately prior to such meeting, then the Rights may not be redeemed for a
period of 90 days after such election if such redemption is reasonably likely to
have the purpose or effect of allowing any person to become an Acquiring Person
or otherwise facilitating the occurrence of a Triggering Event or a transaction
with an Acquiring Person. Immediately upon the action of the Board of Directors
ordering redemption of the Rights, the Rights will terminate and the only right
of the holders of Rights will be to receive the Redemption Price. The Rights may
also be redeemable following certain other circumstances specified in the Rights
Agreement.

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

         Subject to certain exceptions, any of the provisions of the Rights
Agreement may be amended by the Board of Directors of the Company prior to such
time as the Rights are no longer redeemable.

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to the Company's Current Report on Form 8-K
dated October 30, 1998. A copy of the Rights Agreement is available free of
charge from the Company. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
