                               RIGHTS AGREEMENT

      AMENDED AND RESTATED RIGHTS AGREEMENT, dated as of February 10, 1994
(the "Agreement"), between COLUMBIA/HCA HEALTHCARE CORPORATION, a Delaware
corporation (the "Corporation"), and MID-AMERICA BANK OF LOUISVILLE & TRUST
COMPANY, a banking and trust corporation organized under the laws of Kentucky
(the "Rights Agent").

      WHEREAS, the Board of Directors of the Corporation authorized and
declared a dividend of one preferred stock purchase right (a "Voting Right")
for each share of Common Stock, $.01 par value (the "Common Stock"), of the
Corporation outstanding on September 1, 1993 (the "Record Date"), upon the
terms and subject to the conditions set forth in the Rights Agreement dated as
of September 1, 1993, between the Corporation and the Rights Agent (the
"Original Agreement");

      WHEREAS, in connection with the merger of HCA-Hospital Corporation of
America ("HCA") into a wholly owned subsidiary of the Corporation, the
Corporation is issuing in exchange for shares of nonvoting common stock of HCA
shares of Nonvoting Common Stock, $.01 par value (the "Nonvoting Common Stock"),
of the Corporation; and

      WHEREAS, the Board of Directors of the Corporation has determined to
issue one nonvoting preferred stock purchase right (a "Nonvoting Right" and,
collectively with the Voting Rights, the "Rights") with each share of
Nonvoting Common Stock and accordingly desires to amend and restate the
Original Agreement to provide for the issuance of Nonvoting 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 then outstanding shares of Common Stock (other than as a
result of a Permitted Offer (as hereinafter defined)) or was such a Beneficial
Owner at any time after the date hereof, whether or not such Person continues
to be the Beneficial Owner of 15% or more of the then outstanding shares of
Common Stock. Notwithstanding the foregoing, (A) the term "acquiring person"
shall not include (i) the Corporation, (ii) any Subsidiary of the Corporation,
(iii) any employee benefit plan of the   Corporation or of any Subsidiary of
the Corporation, (iv) any Person or entity organized, appointed or established
by the Corporation for or



pursuant to the terms of any such plan or (v) any Person who or which,
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 15% or more of the then outstanding shares of Common Stock
as a result of the acquisition of shares of Common Stock directly from the
Corporation and (B) no Person shall be deemed to be an "Acquiring Person"
either (x) as a result of the acquisition of shares of Common Stock by the
Corporation which, by reducing the number of shares of Common Stock
outstanding, increases the proportional number of shares beneficially owned by
such Person; except that if (i) a Person would become an Acquiring Person (but
for the operation of this subclause (x)) as a result of the acquisition of
shares of Common Stock by the Corporation and (ii) after such share
acquisition by the Corporation, such Person becomes the Beneficial Owner of
any additional shares of Common Stock, then such Person shall be deemed an
Acquiring Person or (y) if (i) within 5 days after such Person would otherwise
have become an Acquiring Person (but for the operation of this subclause (y)),
such Person notifies the Board of Directors that such Person did so
inadvertently and (ii) within 2 days after such notification, such Person is
the Beneficial Owner of less than 15% of the outstanding shares of Common
Stock.

      (b) "Act" shall mean the Securities Act of 1933, as amended and as in
effect on the date of this Agreement.

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

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

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

            (ii) which such Person or any of such Person's Affiliates or
      Associates has: (A) the right to acquire (whether such right is
      exercisable immediately or only after the passage of time) pursuant to
      any agreement, arrangement or understanding, or upon the exercise of
      conversion rights, exchange rights, rights (other than the Rights),
      warrants or options, or otherwise; provided, however, that a Person
      shall not be deemed the Beneficial Owner of, or to beneficially own,
      securities tendered pursuant to a tender or exchange offer made by or on
      behalf of such Person or any of such Person's Affiliates or Associates
      until such tendered securities are accepted for purchase or exchange; or
      (B) the right to vote pursuant to any agreement,

                                        2



      arrangement or understanding; provided, however, that a Person shall not
      be deemed the Beneficial Owner of, or to beneficially own, any security
      if the agreement, arrangement or understanding to vote such security
      (1)(x) arises solely from a revocable proxy or consent given to such
      Person in response to a public proxy or consent solicitation made
      pursuant to, and in accordance with, the applicable rules and
      regulations promulgated under the Exchange Act and (y) is not also then
      reportable on Schedule 13D under the Exchange Act (or any comparable or
      successor report) or (2) arises solely from actions of such Person which
      are within the exemption set forth in paragraph (b)(1) of Rule 14a-2
      under the Exchange Act (or any comparable or successor provision); 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) relating to the acquisition,
      holding, voting (except to the extent contemplated by the proviso to
      Section l(d)(ii)(B)) or disposing of any securities of the Corporation.
      Notwithstanding anything in this definition of Beneficial Ownership to
      the contrary, the phrase "then outstanding," when used with reference to
      a Person's Beneficial Ownership of securities of the Corporation, shall
      mean the number of such securities then issued and outstanding together
      with the number of such securities not then actually issued and
      outstanding which such Person would be deemed to own beneficially
      hereunder.

      (e) "Business Day" shall mean any day other than a Saturday, Sunday or
United States federal holiday.

      (f) "close of business" on any given date shall mean 5:00 P.M., New York
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.

      (g) "Common Stock" when used with reference to the Corporation shall
mean the shares of Common Stock of the Corporation referred to in the recitals
hereof or, in the event of a subdivision, combination or consolidation with
respect to such shares of Common Stock, the shares of Common Stock resulting
from such subdivision, combination or consolidation. "Common Stock" when used
with reference to any Person other than the Corporation shall mean the capital
stock (or equity interest) with the greatest voting power of such other Person
or, if such

                                        3



other Person is a Subsidiary of another Person, the Person or Persons which
ultimately control such first-mentioned Person.

      (h) "Distribution Date" shall have the meaning set forth in Section 3
hereof.

      (i) "Final Expiration Date" shall have the meaning set forth in Section
7 hereof.

      (j) "Nonvoting Common Stock" shall mean the shares of Nonvoting Common
Stock of the Corporation referred to in the recitals hereof or, in the event
of a subdivision, combination or consolidation with respect to such shares of
Nonvoting Common Stock, the shares of Nonvoting Common Stock resulting from
such subdivision, combination or consolidation.  "Nonvoting Common Stock" when
used with reference to any Person other than the Corporation shall mean
nonvoting capital stock of such other Person or, if such other Person is a
Subsidiary of another Person, the Person or Persons which ultimately control
such first-mentioned Person, which is identical to the Common Stock of such
Person or Persons, except that such stock shall have substantially the same
voting rights as the Nonvoting Common Stock of the Corporation.

      (k) "Permitted Offer" shall mean a tender or exchange offer which is for
all outstanding shares of Common Stock at a price and on terms determined,
prior to the purchase of shares under such tender or exchange offer, by at
least a majority of the members of the Board of Directors who are not officers
of the Corporation and who are not Acquiring Persons or Affiliates,
Associates, nominees or representatives of an Acquiring Person, to be adequate
(taking into account all factors that such directors deem relevant including,
without limitation, prices that could reasonably be achieved if the
Corporation or its assets were sold on an orderly basis designed to realize
maximum value) and otherwise in the best interests of the Corporation and its
stockholders (other than the Person or any Affiliate or Associate thereof on
whose behalf the offer is being made) taking into account all factors that
such directors may deem relevant.

      (l) "Person" shall mean any individual, firm, partnership, corporation,
trust, association, joint venture or other entity, and shall include any
successor (by merger or otherwise) of such entity.

      (m) "Preferred Stock" shall mean, individually and collectively, the
shares of Series A Participating Preferred Stock ("Series A Preferred Stock")
and Series B Participating Preferred Stock ("Series B Preferred Stock"), par
value $.01 per share, of the Corporation, having the relative rights,
preferences and limitations set forth in Appendix A hereto.

                                        4



      (n) "Redemption Date" shall have the meaning set forth in Section 7
hereof.

      (o) "Section 11(a)(ii) Event" shall mean any event described in Section
11(a)(ii) hereof.

      (p) "Section 13 Event" shall mean any event described in clause (x), (y)
or (z) of Section 13(a) hereof.

      (q) "Stock Acquisition Date" shall mean the first date of public
announcement (which, for purposes of this definition, shall include, without
limitation, a report filed pursuant to the Exchange Act) by the Corporation or
an Acquiring Person that an Acquiring Person has become such; provided, that,
if such Person is determined not to have become an Acquiring Person pursuant
to Section 1(a)(B)(y) hereof, then no Stock Acquisition Date shall be deemed
to have occurred.

      (r) "Subsidiary" of any Person shall mean any corporation or other
Person of which a majority of the voting power of the voting equity securities
or equity interests is owned, directly or indirectly, by such Person.

      (s) "Triggering Event" shall mean any Section 11(a)(ii) Event or any
Section 13 Event.

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

      SECTION 3.  ISSUANCE OF RIGHT CERTIFICATES.  (a) Until the earlier
of (i) the Stock Acquisition Date or (ii) the close of business on the tenth
day (or such later date as may be determined by action of the Corporation's
Board of Directors) after the date of the commencement by any Person (other
than the Corporation, any Subsidiary of the Corporation, any employee benefit
plan of the Corporation or of any Subsidiary of the Corporation or any Person
or entity organized, appointed or established by the Corporation for or
pursuant to the terms of any such plan) of, or of the first public
announcement of the intention of any Person (other than the Corporation, any
Subsidiary of the Corporation, any employee benefit plan of the Corporation or
of any Subsidiary of the Corporation or any Person or entity

                                        5



organized, appointed or established by the Corporation for or pursuant to the
terms of any such plan) to commence (which intention to commence remains in
effect for five Business Days after such announcement), a tender or exchange
offer the consummation of which would result in any Person becoming an
Acquiring Person (including, in the case of both (i) and (ii), any such date
which is after the date of this Agreement and prior to the issuance of the
Rights), the earlier of such dates being herein referred to as the
"Distribution Date," (x) the Rights will be evidenced by the certificates for
shares of Common Stock or Nonvoting Common Stock registered in the names of
the holders thereof (which certificates shall also be deemed to be Right
Certificates and shall represent, in the case of certificates for shares of
Common Stock, the same number of Voting Rights or, in the case of certificates
for shares of Nonvoting Common Stock, the same number of Nonvoting Rights) and
not by separate Right Certificates and (y) the right to receive Right
Certificates will be transferable only in connection with the transfer of the
underlying shares of Common Stock or Nonvoting Common Stock (including a
transfer to the Corporation); provided, however, that if a tender offer is
terminated prior to the occurrence of a Distribution Date, then no
Distribution Date shall occur as a result of such tender offer. As soon as
practicable after the Distribution Date, the Corporation will prepare and
execute, the Rights Agent will countersign, and the Corporation will send or
cause to be sent by first-class, postage-prepaid mail, to each record holder
of shares of Common Stock or Nonvoting Common Stock as of the close of
business on the Distribution Date, at the address of such holder shown on the
records of the Corporation, a Right Certificate, substantially in the form of
Exhibit I hereto (a "Right Certificate"), evidencing one Voting Right for each
share of Common Stock or one Nonvoting Right for each share of Nonvoting
Common Stock so held. As of and after the Distribution Date, the Rights will
be evidenced solely by such Right Certificates.

      (b) Certificates for shares of Common Stock or Nonvoting Common Stock
which are outstanding on the Record Date or which become outstanding
(including, without limitation, reacquired shares of Common Stock or Nonvoting
Common Stock referred to in the last sentence of this paragraph (b)) after the
Record Date but prior to the earliest of the Distribution Date, the Redemption
Date and the Final Expiration Date, shall be deemed also to be certificates
for Rights, and shall bear the following legend (or any similar legend required
by the original Rights Agreement dated as of September 1, 1993):

      This certificate also evidences and entitles the holder hereof to
certain rights as set forth in an Amended and Restated  Rights Agreement
between Columbia/HCA Healthcare Corporation and Mid-America Bank of Louisville
& Trust Company, as Rights Agent, dated as of February 10, 1994 (the "Rights
Agreement"), the terms of which are hereby incorporated herein by reference
and a copy of which is on file at the principal executive offices of
Columbia/HCA Healthcare

                                        6



Corporation.  Under certain circumstances, as set forth in the Rights
Agreement, such Rights will be evidenced by separate certificates and will no
longer be evidenced by this certificate. Columbia/HCA Healthcare Corporation
will mail to the holder of this certificate a copy of the Rights Agreement
without charge 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 an Affiliate or
Associate thereof (as defined in the Rights Agreement) and certain related
persons, 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 Distribution Date, the Rights associated with the shares of Common Stock
or Nonvoting Common Stock represented by such certificates shall be evidenced
by such certificates alone, and the surrender for transfer of any such
certificate shall also constitute the transfer of the Rights associated with
the shares of Common Stock or Nonvoting Common Stock represented thereby. In
the event that the Corporation purchases or acquires any shares of Common
Stock or Nonvoting Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such shares of Common Stock or
Nonvoting Common Stock shall be deemed canceled and retired so that the
Corporation shall not be entitled to exercise any Rights associated with the
shares of Common Stock or Nonvoting Common Stock which are no longer
outstanding.

      SECTION 4.  FORM OF RIGHT CERTIFICATES.  (a) The Right Certificates
(and the forms of election to purchase and of assignment to be printed on the
reverse thereof) shall be substantially in the form set forth in Exhibit I
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Corporation may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Rights may from time to time be listed, or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the
Right Certificates shall entitle the holders thereof to purchase such number
of one-hundredths of a share of, in the case of Voting Rights, Series A
Preferred Stock or, in the case of Nonvoting Rights, Series B Preferred Stock,
as shall be set forth therein at the price per one one-hundredth of a share
set forth therein (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 Right Certificate issued pursuant to Section 3(a) or Section 22
hereof that represents Rights which are null and void pursuant to Section 7(e)
of

                                        7



this Agreement and any Right Certificate issued pursuant to Section 6 or
Section 11 hereof upon transfer, exchange, replacement or adjustment of any
other Right Certificate referred to in this sentence, shall contain (to the
extent feasible) the following legend:

      The Rights represented by this Right 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 Right Certificate and the Rights
represented hereby are null and void.

      The provisions of Section 7(e) of this Rights Agreement shall be
operative whether or not the foregoing legend is contained on any such Right
Certificate.

      SECTION 5.  COUNTERSIGNATURE AND REGISTRATION.  The Right
Certificates shall be executed on behalf of the Corporation by its Chairman of
the Board, its Chief Executive Officer, its President, any of its Vice
Presidents, or its Treasurer, either manually or by facsimile signature, shall
have affixed thereto the Corporation's seal or a facsimile thereof, and shall
be attested by the Secretary or an Assistant Secretary of the Corporation,
either manually or by facsimile signature. The Right Certificates shall be
countersigned by the Rights Agent and shall not be valid for any purpose
unless so countersigned. In case any officer of the Corporation who shall have
signed any of the Right Certificates shall cease to be such officer of the
Corporation before countersignature by the Rights Agent and issuance and
delivery by the Corporation, such Right Certificates may nevertheless be
countersigned by the Rights Agent and issued and delivered by the Corporation
with the same force and effect as though the person who signed such Right
Certificates had not ceased to be such officer of the Corporation; and any
Right Certificate may be signed on behalf of the Corporation by any person
who, at the actual date of the execution of such Right Certificate, shall be a
proper officer of the Corporation to sign such Right Certificate, although at
the date of the execution of this Rights Agreement any such person was not
such an officer.

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

                                        8



      SECTION 6.  TRANSFER, SPLIT-UP, COMBINATION AND EXCHANGE OF RIGHT
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES.
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 earlier of the Redemption Date or the
Final Expiration Date, any Right Certificate or Right Certificates may be
transferred, split up, combined or exchanged for another Right Certificate or
Right Certificates, entitling the registered holder to purchase a like number
of one one-hundredths of a share of Preferred Stock (or, following a
Triggering Event, other securities, as the case may be) as the Right
Certificate or Right 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 Right Certificate or
Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office or
offices of the Rights Agent designated for such purpose. Neither the Rights
Agent nor the Corporation shall be obligated to take any action whatsoever
with respect to the transfer of any such surrendered Right Certificate until
the registered holder shall have completed and signed the certificate
contained in the form of assignment on the reverse side of such Right
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 Corporation 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 Right
Certificate or Right Certificates, as the case may be, as so requested. The
Corporation may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer, split
up, combination or exchange of Right Certificates.

      Upon receipt by the Corporation and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation
of a Right Certificate, and, in case of loss, theft or destruction, of
indemnity or security reasonably satisfactory to them, and, at the
Corporation's request, reimbursement to the Corporation and the Rights Agent
of all reasonable expenses incidental thereto, and upon surrender to the
Rights Agent and cancellation of the Right Certificate if mutilated, the
Corporation will make and deliver a new Right Certificate of like tenor to the
Rights Agent for countersignature and delivery to the registered holder in
lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

      SECTION 7.  EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF
RIGHTS.  (a) Subject to Section 7(e) hereof, the registered holder of any
Right Certificate may

                                        9



exercise the Rights evidenced thereby (except as otherwise provided herein) in
whole or in part at any time after the Distribution Date upon surrender of the
Right Certificate, with the form of election to purchase and the certificate
on the reverse side thereof duly executed, to the Rights Agent at the
principal office or offices of the Rights Agent designated for such purpose,
together with payment of the aggregate Purchase Price for the total number of
one one-hundredths of a share of Preferred Stock (or other securities, as the
case may be) as to which such surrendered Rights are exercised, at or prior to
the earliest of (i) the close of business on September 1, 2003 (the "Final
Expiration Date") and (ii) the time at which the Rights are redeemed as
provided in Section 23 hereof (the "Redemption Date").

      (b) The Purchase Price for each one one-hundredth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $100,
shall be subject to adjustment from time to time as provided in the next two
sentences and in Sections 11 and 13(a) hereof and shall be payable in
accordance with Section 7(c) below. Anything in this Agreement to the contrary
notwithstanding, in the event that at any time after the date of this
Agreement and prior to the Distribution Date, the Corporation shall (i)
declare or pay any dividend on the Common Stock payable in shares of Common
Stock or (ii) effect a subdivision, combination or consolidation of the Common
Stock (by reclassification or otherwise than by payment of dividends in shares
of Common Stock) into a greater or lesser number of shares of Common Stock,
then in any such case, each share of Common Stock outstanding following such
subdivision, combination or consolidation shall continue to have a Right
associated therewith and the Purchase Price following any such event shall be
proportionately adjusted to equal the result obtained by multiplying the
Purchase Price immediately prior to such event by a fraction the numerator of
which shall be the total number of shares of Common Stock outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
following the occurrence of such event. The same adjustment shall be made with
respect to each share of Nonvoting Common Stock and the associated Right in
the case of (i) any dividend on the Nonvoting Common Stock payable in shares
of Nonvoting Common Stock or (ii) any subdivision, combination, or
consolidation of the Nonvoting Common Stock (by reclassification or otherwise
than by payment of dividends in shares of Nonvoting Common Stock).  The
adjustments provided for in the two preceding sentences shall be made
successively whenever such a dividend is declared or paid or such a
subdivision, combination or consolidation is effected.

      (c) Upon receipt of a Right Certificate representing exercisable Rights,
with the form of election to purchase and the certificate duly executed,
accompanied

                                       10



by payment of the Purchase Price for the shares of Preferred Stock (or other
securities, as the case may be) to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 6 hereof by certified check, cashier's
check or money order payable to the order of the Corporation, the Rights Agent
shall thereupon promptly (i) (A) requisition from any transfer agent of the
shares of Preferred Stock certificates for the number of shares of Preferred
Stock to be purchased and the Corporation hereby irrevocably authorizes its
transfer agent to comply with all such requests, or (B) if the Corporation, in
its sole discretion, shall have elected to deposit the shares of Preferred
Stock issuable upon exercise of the Rights thereunder into a depository,
requisition from the depository agent depository receipts representing such
number of one one-hundredths of a share of Preferred Stock as are to be
purchased (in which case certificates for the shares of Preferred Stock
represented by such receipts shall be deposited by the transfer agent with the
depository agent) and the Corporation will direct the depository agent to
comply with such requests, (ii) when appropriate, requisition from the
Corporation the amount of cash to be paid in lieu of issuance of fractional
shares in accordance with Section 14 hereof, (iii) after receipt of such
certificates or depository receipts, cause the same to be delivered to or upon
the order of the registered holder of such Right Certificate, registered in
such name or names as may be designated by such holder and (iv) when
appropriate, after receipt thereof, deliver such cash to or upon the order of
the registered holder of such Right Certificate. In the event that the
Corporation is obligated to issue other securities (including Common Stock
and/or Nonvoting Common Stock) of the Corporation pursuant to Section 11(a)
hereof, the Corporation will make all arrangements necessary so that such
other securities are available for distribution by the Rights Agent, if and
when appropriate.

      In addition, in the case of an exercise of the Rights by a holder
pursuant to Section 11(a)(ii), the Rights Agent shall return such Right
Certificate to the registered holder thereof after imprinting, stamping or
otherwise indicating thereon that the rights represented by such Right
Certificate no longer include the rights provided by Section 11(a)(ii) of the
Rights Agreement and if less than all the Rights represented by such Right
Certificate were so exercised, the Rights Agent shall indicate on the Right
Certificate the number of Rights represented thereby which continue to include
the rights provided by Section 11(a)(ii).

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

                                       11



appropriate notation on the Right Certificate with respect to those Rights
exercised.

      (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 Affiliate or Associate of
an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any
Affiliate or Associate thereof) who becomes a transferee after the Acquiring
Person becomes such or (iii) a transferee of an Acquiring Person (or of any
Affiliate or Associate thereof) 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 a continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a
transfer which the Board of Directors of the Corporation has determined is
part of a plan, arrangement or understanding which has as a primary purpose or
effect the avoidance of this Section 7(e), shall become null and void without
any further action and no holder of such Rights shall have any rights
whatsoever with respect to such Rights, whether under any provision of this
Agreement or otherwise. The Corporation 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 Right 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 Corporation shall be obligated to undertake any
action with respect to a registered holder upon the occurrence of any
purported exercise as set forth in this Section 7 unless such registered
holder shall have (i) completed and signed the certificate contained in the
form of election to purchase set forth on the reverse side of the Right
Certificate surrendered for such exercise and (ii) provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner)
or Affiliates or Associates thereof as the Corporation shall reasonably
request.

      SECTION 8.  CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES.  All
Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Corporation or to any
of its agents, be delivered to the Rights Agent for cancellation or in
canceled form, or, if surrendered to the Rights Agent, shall be canceled by
it, and no Right Certificates shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Agreement. The
Corporation shall deliver to the Rights Agent for

                                       12



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

      SECTION 9.  RESERVATION AND AVAILABILITY OF PREFERRED STOCK.  The
Corporation covenants and agrees that at all times prior to the occurrence of
a Section 11(a)(ii) Event it will cause to be reserved and kept available out
of its authorized and unissued shares of Preferred Stock, or any authorized
and issued shares of Preferred Stock held in its treasury, the number of
shares of Preferred Stock that will be sufficient to permit the exercise in
full of all outstanding Rights and, after the occurrence of a Section
11(a)(ii) Event, shall, to the extent reasonably practicable, so reserve and
keep available a sufficient number of shares of Common Stock and Nonvoting
Common Stock (and/or other securities) which may be required to permit the
exercise in full of the Rights pursuant to this Agreement.

      So long as the shares of Preferred Stock (and, after the occurrence of a
Section 11(a)(ii) Event, Common Stock, Nonvoting Common Stock or any other
securities) issuable upon the exercise of the Rights may be listed on any
national securities exchange, the Corporation shall use its best efforts to
cause, from and after such time as the Rights become exercisable, all shares
reserved for such issuance to be listed on such exchange upon official notice
of issuance upon such exercise.

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

      The Corporation further covenants and agrees that it will pay when due
and payable any and all United States federal and state transfer taxes and
charges which may be payable in respect of the issuance or delivery of the
Right Certificates or of any shares of Preferred Stock (or Common Stock,
Nonvoting Common Stock and/or other securities, as the case may be) upon the
exercise of Rights. The Corporation shall not, however, be required to pay any
transfer tax which may be payable in respect of any transfer or delivery of
Right Certificates to a person other than, or the issuance or delivery of
certificates or depository

                                       13



receipts for the shares of Preferred Stock (or Common Stock, Nonvoting Common
Stock and/or other securities, as the case may be) in a name other than that
of, the registered holder of the Right Certificate evidencing Rights
surrendered for exercise, or to issue or to deliver any certificates or
depository receipts for shares of Preferred Stock (or Common Stock, Nonvoting
Common Stock and/or other securities, as the case may be) upon the exercise of
any Rights, until any such tax shall have been paid (any such tax being
payable by the holder of such Right Certificate at the time of surrender) or
until it has been established to the Corporation's reasonable satisfaction
that no such tax is due.

      The Corporation shall use its best efforts to (i) file, as soon as
practicable following the Stock Acquisition Date, 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 and the rules and regulations thereunder)
until the date of the expiration of the rights provided by Section 11(a)(ii).
The Corporation shall also take such action as may be appropriate under the
blue sky laws of the various states.

      SECTION 10.  PREFERRED STOCK RECORD DATE.  Each person in whose name
any certificate for shares of Preferred Stock (or Common Stock, Nonvoting
Common Stock and/or other securities, as the case may be) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder
of record of the shares of Preferred Stock (or Common Stock, Nonvoting Common
Stock and/or other securities, as the case may be) represented thereby on, and
such certificate shall be dated, the date upon which the Right Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer taxes) was made; provided, however, that, if the
date of such surrender and payment is a date upon which the Preferred Stock
(or Common Stock, Nonvoting Common Stock and/or other securities, as the case
may be) transfer books of the Corporation are closed, such person shall be
deemed to have become the record holder of such shares on, and such
certificate shall be dated, the next succeeding Business Day on which the
Preferred Stock (or Common Stock, Nonvoting Common Stock and/or other
securities, as the case may be) transfer books of the Corporation are open.

      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.

                                       14



      (a)   (i) In the event the Corporation shall at any time after the date
      of this Agreement (A) declare a dividend on the shares of Preferred
      Stock payable in Preferred Stock, (B) subdivide the outstanding shares
      of Preferred Stock, (C) combine the outstanding shares of Preferred
      Stock into a smaller number of shares of Preferred Stock or (D) issue
      any shares of its capital stock in a reclassification of the Preferred
      Stock (including any such reclassification in connection with a
      consolidation or merger in which the Corporation 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 capital stock issuable on such date, shall be proportionately
      adjusted so that the holder of any Right exercised after such time shall
      be entitled to receive the aggregate number and kind of shares of
      capital stock which, if such Right had been exercised immediately prior
      to such date and at a time when the Preferred Stock transfer books of
      the Corporation were open, such holder would have owned upon such
      exercise and been entitled to receive by virtue of such dividend,
      subdivision, combination or reclassification; provided, however, that in
      no event shall the consideration to be paid upon the exercise of one
      Right be less than the aggregate par value of the shares of capital
      stock of the Corporation issuable upon exercise of one Right. If an
      event occurs which would require an adjustment under both Section
      11(a)(i) and Section 11(a)(ii), 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).

            (ii) In the event any Person, alone or together with its
      Affiliates and Associates, shall become an Acquiring Person, then proper
      provision shall be made so that each holder of a Right (except as
      provided below and in Section 7(e) hereof) shall, for a period of 60
      days after the later of the occurrence of any such event or the
      effective date of an appropriate registration statement under the Act
      pursuant to Section 9 hereof, have a right to receive, upon exercise
      thereof at a price equal to the then current Purchase Price, in
      accordance with the terms of this Agreement, such number of shares of
      (in the case of Voting Rights) Common Stock or (in the case of Nonvoting
      Rights) Nonvoting Common Stock (or, in the discretion of the Board of
      Directors, one one-hundredths of a share of Preferred Stock (which shall
      be Series A Preferred Stock in the case of Voting Rights and Series B
      Preferred Stock in the case of Nonvoting Rights)) as shall equal the
      result obtained by (x) multiplying the then current Purchase Price by
      the then number of one one-hundredths of a share of Preferred Stock for
      which a Right was exercisable immediately prior to the first occurrence
      of a

                                       15



      Section 11(a)(ii) Event and dividing that product by (y) 50% of the then
      current per share market price of the Corporation's Common Stock
      (determined pursuant to Section 11(d) hereof) on the date of such first
      occurrence (such number of shares being referred to as the "Adjustment
      Shares"); provided, however, that if the transaction that would
      otherwise give rise to the foregoing adjustment is also subject to the
      provisions of Section 13 hereof, then only the provisions of Section 13
      hereof shall apply and no adjustment shall be made pursuant to this
      Section 11(a)(ii).

            (iii) In the event that there shall not be sufficient treasury
      shares or authorized but unissued (and unreserved) shares of Common
      Stock and Nonvoting Common Stock to permit the exercise in full of the
      Rights in accordance with the foregoing subparagraph (ii) and the Rights
      become so exercisable (and the Board has determined to make the Rights
      exercisable into fractions of a share of Preferred Stock),
      notwithstanding any other provision of this Agreement, to the extent
      necessary and permitted by applicable law, each Right shall thereafter
      represent the right to receive, upon exercise thereof at the then
      current Purchase Price in accordance with the terms of this Agreement,
      (x) a number of (or fractions of) shares of Common Stock or Nonvoting
      Common Stock, as the case may be (up to the maximum number of shares of
      Common Stock or Nonvoting Common Stock which may permissibly be issued),
      and (y) one one-hundredths of a share of Preferred Stock (which shall be
      Series A Preferred Stock in the case of Voting Rights and Series B
      Preferred Stock in the case of Nonvoting Rights) or a number of, or
      fractions of other equity securities of the Corporation (or, in the
      discretion of the Board of Directors, debt) which the Board of Directors
      of the Corporation has determined to have the same aggregate current
      market value (determined pursuant to Section 11(d)(i) and (ii) hereof,
      to the extent applicable) as one share of Common Stock (such number of
      shares of, or fractions of a share of, Preferred Stock, debt, or other
      equity securities (provided that, in the case of other equity securities
      issuable upon exercise of Nonvoting Rights, the Board of Directors shall
      use its best efforts to issue nonvoting equity securities) or debt of
      the Corporation being referred to as a "capital stock equivalent"),
      equal in the aggregate to the number of Adjustment Shares; provided,
      however, if sufficient shares of Common Stock, Nonvoting Common Stock
      and/or capital stock equivalents are unavailable, then the Corporation
      shall, to the extent permitted by applicable law, take all such action
      as may be necessary to authorize additional shares of Common Stock,
      Nonvoting Common Stock or capital stock equivalents for issuance upon
      exercise of the Rights, including the calling of a meeting of
      stockholders; and provided, further, that if the Corporation is unable
      to cause sufficient shares of Common Stock,

                                       16



      Nonvoting Common Stock and/or capital stock equivalents to be available
      for issuance upon exercise in full of the Rights, then each Right shall
      thereafter represent the right to receive the Adjusted Number of Shares
      upon exercise at the Adjusted Purchase Price (as such terms are
      hereinafter defined). As used herein, the term "Adjusted Number of
      Shares" shall mean that number of shares (or fractions of shares) of
      Common Stock, Nonvoting Common Stock and/or capital stock equivalents
      equal to the product of (x) the number of Adjustment Shares and (y) a
      fraction, the numerator of which is the number of shares of Common
      Stock, Nonvoting Common Stock and/or capital stock equivalents available
      for issuance upon exercise of the Rights and the denominator of which is
      the aggregate number of Adjustment Shares otherwise issuable upon
      exercise in full of all Rights (assuming there were a sufficient number
      of shares of Common Stock and Nonvoting Common Stock available) (such
      fraction being referred to as the "Proration Factor"). The "Adjusted
      Purchase Price" shall mean the product of the Purchase Price and the
      Proration Factor.  In the event that there are insufficient shares of
      Common Stock, Nonvoting Common Stock and capital stock equivalents
      available for issuance upon exercise of the Rights, the Board of
      Directors shall  establish procedures to allocate the right to receive
      shares of Common Stock, Nonvoting Common Stock and capital stock
      equivalents upon exercise of the Rights pro rata among holders of Voting
      Rights and Nonvoting Rights, provided that, to the extent consistent
      with such proration, shares of Nonvoting Common Stock and other
      nonvoting capital stock shall be allocated to holders of Nonvoting
      Rights and shares of Common Stock and other voting capital stock shall
      be allocated to holders of Voting Rights.

      (b) In case the Corporation shall fix a record date for the issuance of
rights (other than the Rights), options or warrants to all holders of shares
of Preferred Stock entitling them (for a period expiring within 45 calendar
days after such record date) to subscribe for or purchase shares of Preferred
Stock (or shares having the same rights, privileges and preferences as the
Preferred Stock ("preferred stock equivalents")) or securities convertible
into shares of Preferred Stock or preferred stock equivalents at a price per
share of Preferred Stock or preferred stock equivalent (or having a conversion
price per share, if a security convertible into shares of Preferred Stock or
preferred stock equivalents) less than the then current per share market price
of the Preferred Stock (as determined pursuant to Section 11(d) hereof) on
such record date, the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of shares of Preferred Stock outstanding on such record date plus the
number of shares of Preferred Stock which the aggregate

                                       17



offering price of the total number of shares of Preferred Stock and/or
preferred 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 per share market price, and the denominator of which
shall be the number of shares of Preferred Stock outstanding on such record
date plus the number of additional shares of Preferred Stock and/or preferred
stock equivalents to be offered for subscription or purchase (or into which
the convertible securities so to be offered are initially convertible);
provided, however, that in no event shall the consideration to be paid upon
the exercise of one Right be less than the aggregate par value of the shares
of capital stock of the Corporation issuable upon exercise of one Right. In
case such subscription price may be paid in a consideration part or all of
which shall be in a form other than cash, the value of such consideration
shall be determined in good faith by the Board of Directors of the
Corporation, whose determination shall be described in a statement filed with
the Rights Agent and shall be binding on the Rights Agent. Shares of Preferred
Stock owned by or held for the account of the Corporation shall not be deemed
outstanding for the purpose of any such computation. Such adjustments shall be
made successively whenever such a record date is fixed; and in the event that
such rights, options or warrants are not so issued, the Purchase Price shall
be adjusted to be the Purchase Price which would then be in effect if such
record date had not been fixed.

      (c) In case the Corporation shall fix a record date for the making of a
distribution to all holders of shares of Preferred Stock (including any such
distribution made in connection with a consolidation or merger in which the
Corporation is the continuing or surviving corporation) of evidences of
indebtedness or assets (other than a regular quarterly cash dividend or a
dividend payable in shares of Preferred Stock) or subscription rights or
warrants (excluding those referred to in Section 11(b) hereof), the Purchase
Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the then current per share
market price (as determined pursuant to Section 11(d) hereof) of the Preferred
Stock on such record date, less the fair market value (as determined in good
faith by the Board of Directors of the Corporation, whose determination shall
be described in a statement filed with the Rights Agent and shall be binding
on the Rights Agent) of the portion of the assets or evidences of indebtedness
so to be distributed or of such subscription rights or warrants applicable to
one share of Preferred Stock and the denominator of which shall be such
current per share market price of the Preferred Stock; provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right
be less than the aggregate par value of the shares of capital stock of the
Corporation to be issued upon exercise of one Right. Such adjustments shall be

                                       18



made successively whenever such a record date is fixed; and in the event that
such distribution is not so made, the Purchase Price shall again be adjusted
to be the Purchase Price which would then be in effect if such record date had
not been fixed.

      (d)   (i) For the purpose of any computation hereunder, the "current per
      share market price" of any security (a "Security" for the purpose of
      this Section 11(d)(i)) on any date shall be deemed to be the average of
      the daily closing prices per share of such Security for the thirty (30)
      consecutive Trading Days (as such term is hereinafter defined)
      immediately prior to such date; provided, however, that in the event
      that the current per share market price of the Security is determined
      during a period following the announcement by the issuer of such
      Security of (A) a dividend or distribution on such Security payable in
      shares of such Security or securities convertible into such shares or
      (B) any subdivision, combination or reclassification of such Security
      and prior to the expiration of thirty (30) Trading Days after the
      ex-dividend date for such dividend or distribution or the record date
      for such subdivision, combination or reclassification, then, and in each
      such case, the current per share market price shall be appropriately
      adjusted to reflect the current market price per share equivalent of
      such Security. The closing price for each day shall be the last sale
      price, regular way, or, in case no such sale takes place on such day,
      the average of the closing bid and asked prices, regular way, in either
      case as reported in the principal consolidated transaction reporting
      system with respect to securities listed or admitted to trading on the
      New York Stock Exchange or, if the Security is not listed or admitted to
      trading on the New York Stock Exchange, as reported in the principal
      consolidated transaction reporting system with respect to securities
      listed on the principal national securities exchange on which the
      Security is listed or admitted to trading or, if the Security is not
      listed or admitted to trading on any national securities exchange, the
      last quoted price or, if not so quoted, the average of the high bid and
      low asked prices in the over-the-counter market, as reported by the
      National Association of Securities Dealers, Inc. Automated Quotations
      System ("NASDAQ") or such other system then in use, or, if on any such
      date the Security is not quoted by any such organization, the average of
      the closing bid and asked prices as furnished by a professional market
      maker making a market in the Security selected by the Board of Directors
      of the Corporation. If on any such date no such market maker is making a
      market in the Security, the fair value of the Security on such date as
      determined in good faith by the Board of Directors of the Corporation
      shall be used. The term "Trading Day" shall mean a day on which the
      principal national securities exchange on which the Security is listed
      or admitted to trading is

                                       19



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

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

      (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 1% in the Purchase Price; provided, however,
that any adjustments which by reason of this Section 11(e) are not required to
be made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this Section 11 shall be made to the
nearest cent or to the nearest one one-hundredth of a share of Preferred Stock
or one ten-thousandth of any other share or security, as the case may be.
Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i)
three (3) years from the date of the transaction which mandates such
adjustment or (ii) the Final Expiration Date.

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

                                       20



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

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

      (i) Irrespective of any adjustment or change in the Purchase Price or
the number of one one-hundredths of a share of Preferred Stock issuable upon
the exercise of the Rights, the Right Certificates theretofore and thereafter
issued may continue to express the Purchase Price and the number of one
one-hundredths of

                                       21



a share of Preferred Stock which were expressed in the initial Right
Certificates issued hereunder.

      (j) Before taking any action that would cause an adjustment reducing the
Purchase Price below the then par value, if any, of the number of one
one-hundredths of a share of Preferred Stock, shares of Common Stock,
Nonvoting Common Stock or other securities issuable upon exercise of the
Rights, the Corporation shall take any corporate action which may, in the
opinion of its counsel, be necessary in order that the Corporation may validly
and legally issue such number of fully paid and non-assessable one
one-hundredths of a share of Preferred Stock, shares of Common Stock,
Nonvoting Common Stock or other securities at such adjusted Purchase Price.

      (k) 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 Corporation may elect to defer until the occurrence of
such event the issuance to the holder of any Right exercised after such record
date the shares of Preferred Stock, Common Stock, Nonvoting Common Stock or
other securities of the Corporation, if any, issuable upon such exercise over
and above the shares of Preferred Stock, Common Stock, Nonvoting Common Stock
or other securities of the Corporation, if any, issuable upon exercise on the
basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Corporation shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

      (l) Anything in this Section 11 to the contrary notwithstanding, the
Corporation 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 it in its sole discretion shall determine to be advisable
in order that (i) any consolidation or subdivision of the Preferred Stock,
(ii) issuance wholly for cash of Preferred Stock at less than the current
market price, (iii) issuance wholly for cash of Preferred Stock or securities
which by their terms are convertible into or exchangeable for Preferred Stock,
(iv) stock dividend or (v) issuance of rights, options or warrants referred to
in this Section 11, hereafter made by the Corporation to holders of its
Preferred Stock shall not be taxable to such stockholders.

      (m) The Corporation 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 Corporation in a transaction which does not violate
Section 11(n) hereof), (ii) merge with or into any other Person (other than a
Subsidiary of the Corporation

                                       22



in a transaction which does not violate Section 11(n) 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 Corporation and its
Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Corporation and/or any of its Subsidiaries in one or more transactions each of
which does not violate Section 11(n) hereof), if (x) at the time of or
immediately after such consolidation, merger, sale or transfer there are any
charter or by-law provisions or any rights, warrants or other instruments or
securities outstanding or agreements in effect or other actions taken, which
would materially 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 stockholders of the Person who
constitutes, or would constitute, the "Principal Party" for purposes of
Section 13(a) hereof shall have received a distribution of Rights previously
owned by such Person or any of its Affiliates and Associates. The Corporation
shall not consummate any such consolidation, merger, sale or transfer unless
prior thereto the Corporation and such other Person shall have executed and
delivered to the Rights Agent a supplemental agreement evidencing compliance
with this Section 11(m).

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

      (o) The exercise of Rights under Section 11(a)(ii) shall only result in
the loss of rights under Section 11(a)(ii) to the extent so exercised and
shall not otherwise affect the rights represented by the Rights under this
Agreement, including the rights represented by Section 13.

      SECTION 12.  CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF
SHARES.  Whenever an adjustment is made as provided in Sections 11 or 13
hereof, the Corporation shall promptly (a) prepare a certificate setting forth
such adjustment, and a brief statement of the facts accounting for such
adjustment, (b) file with the Rights Agent and with each transfer agent for
the Common Stock, the Nonvoting Common Stock and the Preferred Stock a copy of
such certificate and (c) mail a brief summary thereof to each holder of a
Right Certificate in accordance with Section 25 hereof. The Rights Agent shall
be fully protected in relying on any such certificate and on any adjustment
therein contained and shall not be deemed to

                                       23



have knowledge of such 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, on or following the Stock Acquisition
Date, directly or indirectly, (x) the Corporation shall consolidate with, or
merge with and into, any Person, (y) the Corporation shall consolidate with,
or merge with, any Person, and the Corporation shall be the continuing or
surviving corporation of such consolidation or merger (other than, in a case
of any transaction described in (x) or (y), a merger or consolidation which
would result in all of the securities generally entitled to vote in the
election of directors ("voting securities") of the Corporation outstanding
immediately prior thereto, continuing to represent (either by remaining
outstanding or by being converted into securities of the surviving entity) all
of the voting securities of the Corporation or such surviving entity
outstanding immediately after such merger or consolidation and the holders of
such securities not having changed as a result of such merger or
consolidation) or (z) the Corporation 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 Corporation
and its Subsidiaries (taken as a whole) to any Person, then, and in each such
case (except as provided in 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 a price equal to the then current Purchase Price, in accordance with the
terms of this Agreement and in lieu of shares of Preferred Stock, such number
of freely tradable shares of Common Stock (or, in the case of Nonvoting
Rights, shares of Nonvoting Common Stock) of the Principal Party (as
hereinafter defined), not subject to any liens, encumbrances, rights of first
refusal or other adverse claims, as shall equal the result obtained by (A)
multiplying the then current Purchase Price by the number of one
one-hundredths of a share of Preferred Stock for which a Right is then
exercisable (without taking into account any adjustment previously made
pursuant to Section 11(a)(ii)) and dividing that product by (B) 50% of the
then current per share market price of the Common Stock of such Principal
Party (determined pursuant to Section 11(d) hereof) 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 Corporation pursuant to this
Agreement; (iii) the term "Corporation" shall thereafter be deemed to refer to
such Principal Party, it being specifically intended that the provisions of
Section 11 hereof shall apply only to such Principal Party following the first
occurrence of a Section 13 Event; and (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 and Nonvoting

                                       24



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 the shares of
Common Stock or Nonvoting Common Stock thereafter deliverable upon the
exercise of the Rights.

      (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 Corporation 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 (including, if applicable, the Corporation if it is the
      surviving corporation); 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 of
      the foregoing cases, (1) if the shares of Common Stock of such Person
      are not at such time and have 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
      shares of Common Stock of which are and have 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 shares of Common Stock 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 shares of Common Stock having the greatest
      aggregate market value; and (3) in case such Person is owned, directly
      or 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 Corporation shall not consummate any such consolidation, merger,
sale or transfer unless the Principal Party shall have a sufficient number of
shares of its authorized Common Stock and Nonvoting Common Stock which have
not been issued or reserved for issuance to permit the exercise in full of the
Rights in

                                       25



accordance with this Section 13 and unless prior thereto the Corporation 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, sale or transfer mentioned in
paragraph (a) of this Section 13, the Principal Party at its own expense
shall:

            (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 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 Final 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 which comply in all respects with the
      requirements for registration on Form 10 under the Exchange Act.

      The provisions of this Section 13 shall similarly apply to successive
mergers or consolidations or sales or other transfers. The rights under this
Section 13 shall be in addition to the rights to exercise Rights and
adjustments under Section 11(a)(ii) and shall survive any exercise thereof.

      (d) Notwithstanding anything in this Agreement to the contrary, Section
13 shall not be applicable to a transaction described in subparagraphs (x) and
(y) of Section 13(a) if: (i) such transaction is consummated with a Person or
Persons who acquired shares of Common Stock pursuant to a Permitted Offer (or
a wholly owned Subsidiary of any such Person or Persons); (ii) the price per
share of Common Stock offered in such transaction is not less than the price
per share of Common Stock paid to all holders of shares of Common Stock whose
shares were purchased pursuant to such Permitted Offer; and (iii) the form of
consideration offered 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 thereunder
shall expire.

      SECTION 14.  FRACTIONAL RIGHTS AND FRACTIONAL SHARES.  (a) The
Corporation shall not be required to issue fractions of Rights or to
distribute Right Certificates which evidence fractional Rights. In lieu of
such fractional Rights, there shall be

                                       26



paid to the registered holders of the Right Certificates with regard to which
such fractional Rights would otherwise be issuable, an amount in cash equal to
the same fraction of the current market value of a whole Right. For the
purposes of this Section 14(a), the current market value of a whole Right
shall be the closing price of the Rights for the Trading Day immediately prior
to the date on which such fractional Rights would have been otherwise
issuable. The closing price for any day shall be the last sale price, regular
way, or, in case no such sale takes place on such day, the average of the
closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange or, if the Rights
are not listed or admitted to trading on the New York Stock Exchange, as
reported in the principal consolidated transaction reporting system with
respect to securities listed on the principal national securities exchange on
which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use or, if on any such date the Rights are not quoted by any
such organization, the average of the closing bid and asked prices as
furnished by a professional market maker making a market in the Rights
selected by the Board of Directors of the Corporation. If on any such date no
such market maker is making a market in the Rights, the fair value of the
Rights on such date as determined in good faith by the Board of Directors of
the Corporation shall be used.  For the purposes of this Agreement, the
current market value of a Nonvoting Right shall conclusively be deemed to
equal the current market value of a Voting Right.

      (b) The Corporation shall not be required to issue fractions of a share
of Preferred Stock (other than fractions which are one one-hundredth or
integral multiples of one one-hundredth of a share of Preferred Stock) upon
exercise of the Rights or to distribute certificates which evidence fractional
shares of Preferred Stock (other than fractions which are one one-hundredth or
integral multiples of one one-hundredth of a share of Preferred Stock).
Fractions of a share of Preferred Stock in integral multiples of one
one-hundredth of a share of Preferred Stock may, at the election of the
Corporation, be evidenced by depositary receipts, pursuant to an appropriate
agreement between the Corporation and a depositary selected by it; provided
that such agreement shall provide that the holders of such depositary receipts
shall have the rights, privileges and preferences to which they are entitled
as beneficial owners of the shares of Preferred Stock represented by such
depositary receipts. In lieu of fractional shares of Preferred Stock that are
not one one-hundredth or integral multiples of one one-hundredth of a share of
Preferred Stock, the Corporation shall pay to the registered holders of Right
Certificates at the time such Rights are exercised as herein provided an
amount in

                                       27



cash equal to the same fraction of the current market value of one share of
Preferred Stock. For the purposes of this Section 14(b), the current market
value of a share of Preferred Stock shall be the closing price of a share of
Preferred Stock (as determined pursuant to Section 11(d)(ii) hereof) for the
Trading Day immediately prior to the date of such exercise.

      (c) Following the occurrence of one of the transactions or events
specified in Section 11 giving rise to the right to receive shares of Common
Stock, Nonvoting Common Stock, capital stock equivalents (other than Preferred
Stock) or other securities upon the exercise of a Right, the Corporation shall
not be required to issue fractions of shares or units of such Common Stock,
Nonvoting Common Stock, capital stock equivalents or other securities upon
exercise of the Rights or to distribute certificates which evidence fractions
of such Common Stock, Nonvoting Common Stock, capital stock equivalents or
other securities. In lieu of fractional shares or units of such Common Stock,
Nonvoting Common Stock, capital stock equivalents or other securities, the
Corporation may pay to the registered holders of Right Certificates at the
time such Rights are exercised as herein provided an amount in cash equal to
the same fraction of the current market value of a share or unit of such
Common Stock, Nonvoting Common Stock, capital stock equivalents or other
securities. For purposes of this Section 14(c), the current market value shall
be determined in the manner set forth in Section 11(d) hereof for the Trading
Day immediately prior to the date of such exercise and, if such capital stock
equivalent is not traded, each such capital stock equivalent shall have the
value of one one-hundredth of a share of Preferred Stock.  For the purposes of
this Agreement, the current market value of the Nonvoting Common Stock shall
conclusively be deemed to equal the current market value of the Common Stock.

      (d) The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Right or any fractional share upon
exercise of a Right (except as provided above).

      SECTION 15.  RIGHTS OF ACTION.  All rights of action in respect of
this Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the
Right Certificates (and, prior to the Distribution Date, the registered
holders of the Common Stock and Nonvoting Common Stock); and any registered
holder of any Right Certificate (or, prior to the Distribution Date, of the
Common Stock or Nonvoting Common Stock), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Stock or Nonvoting 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 Corporation to

                                       28



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

      SECTION 16.  AGREEMENT OF RIGHT HOLDERS.  Every holder of a Right,
by accepting the same, consents and agrees with the Corporation 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 the associated Common Stock or Nonvoting
Common Stock;

      (b) after the Distribution Date, the Right Certificates are transferable
only on the registry books of the Rights Agent if surrendered at the principal
office or offices of the Rights Agent designated for such purpose, duly
endorsed or accompanied by a proper instrument of transfer and with the
appropriate form fully executed;

      (c) subject to Section 6 and Section 7(f) hereof, the Corporation and
the Rights Agent may deem and treat the person in whose name the Right
Certificate (or, prior to the Distribution Date, the associated Common Stock
or Nonvoting 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 Right Certificate or the associated Common Stock
or Nonvoting Common Stock certificate made by anyone other than the
Corporation or the Rights Agent) for all purposes whatsoever, and neither the
Corporation nor the Rights Agent, subject to the last sentence of Section 7(e)
hereof, shall be bound by any notice to the contrary; and

      (d) notwithstanding anything in this Agreement to the contrary, neither
the Corporation nor the Rights Agent shall have any liability to any holder of
a Right or a beneficial interest in 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

                                       29



performance of such obligation; provided, however, that the Corporation shall
use its best efforts to have any such order, decree or ruling lifted or
otherwise overturned as soon as possible.

      SECTION 17.  RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.  No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the shares of Preferred
Stock or any other securities of the Corporation which may at any time be
issuable on the exercise of the Rights represented thereby, nor shall anything
contained herein or in any Right Certificate be construed to confer upon the
holder of any Right Certificate, as such, any of the rights of a stockholder
of the Corporation or any right to vote for the election of directors or upon
any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in Section 24
hereof), or to receive dividends or other distributions or to exercise any
preemptive or subscription rights, or otherwise, until the Right or Rights
evidenced by such Right Certificate shall have been exercised in accordance
with the provisions hereof.

      SECTION 18.  CONCERNING THE RIGHTS AGENT.  The Corporation agrees to
pay to the Rights Agent reasonable compensation for all services rendered by
it hereunder and, from time to time, on demand of the Rights Agent, its
reasonable expenses and counsel fees and other disbursements incurred in the
administration and execution of this Agreement and the exercise and
performance of its duties hereunder. The Corporation also agrees to indemnify
the Rights Agent for, and to hold it harmless against, any loss, liability or
expense, incurred without negligence, bad faith or willful misconduct on the
part of the Rights Agent, for anything done or omitted by the Rights Agent in
connection with the acceptance and administration of this Agreement, including
the costs and expenses of defending against any claim of liability in the
premises. The indemnity provided for herein shall survive the expiration of
the Rights and the termination of this Agreement.

      The Rights Agent shall be protected and shall incur no liability for, or
in respect of, any action taken, suffered or omitted by it in connection with,
its administration of this Agreement in reliance upon any Right Certificate or
certificate for shares of Common Stock or Nonvoting Common Stock or other
securities of the Corporation, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons.

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

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

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

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

      (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter
(including, without limitation, the identity of an Acquiring Person and the

                                       31



determination of the current market price of any Security) be proved or
established by the Corporation prior to taking or suffering any action
thereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board,
the Chief Executive Officer, the President, any Vice President, the Treasurer
or the Secretary of the Corporation 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 thereunder only for its own
negligence, bad faith or willful misconduct.

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

      (e) The Rights Agent shall not be under any responsibility in respect of
the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Corporation of any covenant or
condition contained in this Agreement or in any Right Certificate; nor shall
it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 7(e) hereof) or any
adjustment required under the provisions of Section 11 or Section 13 hereof or
responsible for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such adjustment
(except with respect to the exercise of Rights evidenced by Right Certificates
after receipt of the certificate described in Section 12 hereof); 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 Preferred Stock, Common
Stock or Nonvoting Common Stock to be issued pursuant to this Agreement or any
Right Certificate or as to whether any shares of Preferred Stock,  Common
Stock or Nonvoting Common Stock will, when issued, be validly authorized and
issued, fully paid and non-assessable.

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

                                       32



by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Agreement.

      (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Treasurer or the Secretary of the Corporation, and to
apply to such officers for advice or instructions in connection with its
duties, and shall not be liable for any action taken or suffered by it in good
faith or lack of action in accordance with instructions of any such officer or
for any delay in acting while waiting for those instructions. Any application
by the Rights Agent for written instructions from the Corporation may, at the
option of the Rights Agent, set forth in writing any action proposed to be
taken or omitted by the Rights Agent under this Agreement and the date on or
after which such action shall be taken or such omission shall be effective.
The Rights Agent shall not be liable for any action taken by, or omission of,
the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date
shall not be less than five Business Days after the date any officer of the
Corporation actually receives such application, unless any such officer shall
have consented in writing to an earlier date) unless, prior to taking any such
action (or the effective date in the case of an omission), the Rights Agent
shall have received written instructions in response to such application
specifying the action to be taken or omitted.

      (h) The Rights Agent and any stockholder, director, officer or employee
of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Corporation or become pecuniarily interested in any
transaction in which the Corporation may be interested, or contract with or
lend money to the Corporation 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 Corporation 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 Corporation resulting from any
such act, default, neglect or misconduct, provided 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

                                       33



of any of its duties hereunder or in the exercise of its rights if there shall
be reasonable grounds for believing that repayment of such funds or adequate
indemnification against such risk or liability is not reasonably assured to
it.

      (k) If, with respect to any Right Certificate surrendered to the Rights
Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has not been
completed, the Rights Agent shall not take any further action with respect to
such requested exercise or transfer without first consulting with the
Corporation.

      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 Corporation
and to each transfer agent of the Common Stock, Nonvoting Common Stock or
Preferred Stock by registered or certified mail, and to the holders of the
Right Certificates by first-class mail. The Corporation may remove the Rights
Agent or any successor Rights Agent upon sixty (60) 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, Nonvoting Common Stock or
Preferred Stock by registered or certified mail, and to holders of the Right
Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Corporation shall
appoint a successor to the Rights Agent. If the Corporation shall fail to make
such appointment within a period of sixty (60) days after giving notice of
such removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of
a Right Certificate (who shall, with such notice, submit his Right Certificate
for inspection by the Corporation), then the registered holder of any Right
Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether
appointed by the Corporation or by such a court, shall be a corporation
organized and doing business under the laws of the United States or of any
state of the United States so long as such corporation is in good standing and
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 has at the time of its appointment as Rights Agent a combined
capital and surplus of at least $100,000,000. 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 Corporation shall file notice thereof in writing

                                       34



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

      SECTION 22.  ISSUANCE OF NEW RIGHT CERTIFICATES.  Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Corporation may, at its option, issue new Right Certificates evidencing Rights
in such form as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Agreement.

      In addition, in connection with the issuance or sale of shares of Common
Stock or Nonvoting Common Stock following the Distribution Date and prior to
the earlier of the Redemption Date and the Final Expiration Date, the
Corporation (a) shall with respect to shares of Common Stock or Nonvoting
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, notes or debentures issued by the Corporation and (b)
may, in any other case, if deemed necessary or appropriate by the Board of
Directors of the Corporation, issue Right Certificates representing the
appropriate number of Rights in connection with such issuance or sale;
provided, however, that (i) the Corporation shall not be obligated to issue
any such Right Certificates if, and to the extent that, the Corporation shall
be advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Corporation or the Person to whom
such Right Certificate would be issued and (ii) no Right Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

      SECTION 23.  REDEMPTION AND TERMINATION.

      (a)   (i) The Board of Directors of the Corporation may, at its option,
      redeem all but not less than all the then outstanding Rights at a
      redemption price of $.01 per Right, as such amount may be appropriately
      adjusted to reflect any stock split, stock dividend or similar
      transaction occurring after the date hereof (such redemption price being
      hereinafter referred to as the "Redemption Price"), at any time prior to
      the earlier of (x) the occurrence of a Section 11(a)(ii) Event or (y)
      the Final Expiration Date.

                                       35



            (ii) In addition, the Board of Directors of the Corporation may,
      at its option, at any time following the occurrence of a Section
      11(a)(ii) Event and the expiration of any period during which the holder
      of Rights may exercise the rights under Section 11(a)(ii) but prior to
      any Section 13 Event redeem all but not less than all of the then
      outstanding Rights at the Redemption Price (x) in connection with any
      merger, consolidation or sale or other transfer (in one transaction or
      in a series of related transactions) of assets or earning power
      aggregating 50% or more of the earning power of the Corporation and its
      subsidiaries (taken as a whole) in which all holders of shares of Common
      Stock are treated alike and not involving (other than as a holder of
      shares of Common Stock being treated like all other such holders) an
      Acquiring Person or (y)(aa) if and for so long as the Acquiring Person
      is not thereafter the Beneficial Owner of 15% of the shares of Common
      Stock and (bb) at the time of redemption no other Persons are Acquiring
      Persons.

      (b) In the case of a redemption permitted under Section 23(a)(i),
immediately upon the date for redemption set forth (or determined in the
manner specified) in a resolution of the Board of Directors of the Corporation
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. In the case of a redemption permitted only under Section
23(a)(ii), evidence of which shall have been filed with the Rights Agent, the
right to exercise the Rights will terminate and represent only the right to
receive the Redemption Price upon the later of ten Business Days following the
giving of such notice or the expiration of any period during which the rights
under Section 11(a)(ii) may be exercised. The Corporation shall promptly give
public notice of any such redemption; provided, however, that the failure to
give, or any defect in, any such notice shall not affect the validity of such
redemption. Within ten (10) days after such date for redemption set forth in a
resolution of the Board of Directors ordering the redemption of the Rights,
the Corporation shall mail a notice of redemption to all the holders of the
then outstanding Rights at their last addresses as they appear upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the transfer agent for the Common Stock and Nonvoting 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. Neither the Corporation nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23 and other
than in connection with the

                                       36



purchase of shares of Common Stock or Nonvoting Common Stock prior to the
Distribution Date.

      (c) The Corporation 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 Stock and Nonvoting Common Stock, and upon such
action, all outstanding Rights and Right Certificates shall be null and void
without any further action by the Corporation.

      SECTION 24.  NOTICE OF CERTAIN EVENTS. (a) In case the Corporation
shall propose (i) to pay any dividend payable in stock of any class to the
holders of shares of its Preferred Stock or to make any other distribution to
the holders of shares of its Preferred Stock (other than a regularly quarterly
cash dividend), (ii) to offer to the holders of shares of its Preferred Stock
rights or warrants to subscribe for or to purchase any additional shares of
Preferred Stock or shares of stock of any class or any other securities,
rights or options, (iii) to effect any reclassification of its Preferred Stock
(other than a reclassification involving only the subdivision of outstanding
shares of Preferred Stock), (iv) to effect any consolidation or merger into or
with any other Person (other than a Subsidiary of the Corporation in a
transaction which does not violate Section 11(n) 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 or more transactions, of 50% or more of the
assets or earning power of the Corporation and its Subsidiaries (taken as a
whole) to any other Person or Persons (other than the Corporation and/or any
of its Subsidiaries in one or more transactions each of which does not violate
Section 11(n) hereof) or (v) to effect the liquidation, dissolution or winding
up of the Corporation, then, in each such case, the Corporation shall give to
each holder of a Right Certificate, in accordance with Section 25 hereof, a
notice of such proposed action to the extent feasible and file a certificate
with the Rights Agent to that effect, which shall specify the record date for
the purposes of such stock dividend, or distribution of rights or warrants, or
the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of shares of Preferred Stock, if
any such date is to be fixed, and such notice shall be so given in the case of
any action covered by clause (i) or (ii) above at least twenty (20) days prior
to the record date for determining holders of the shares of Preferred Stock
for purposes of such action, and in the case of any such other action, at
least twenty (20) days prior to the date of the taking of such proposed

                                       37



action or the date of participation therein by the holders of the shares of
Preferred Stock, whichever shall be the earlier.

      (b) In case of a Section 11(a)(ii) Event, then (i) the Corporation shall
as soon as practicable thereafter give to each holder of a Right Certificate,
in accordance with Section 25 hereof, a notice of the occurrence of such
event, which notice shall describe such event and the consequences of such
event to holders of Rights under Section 11(a)(ii) hereof and (ii) all
references in the preceding paragraph (a) to shares of Preferred Stock shall
be deemed thereafter to refer also to Common Stock, Nonvoting Common Stock
and/or, if appropriate, other securities of the Corporation.

      SECTION 25.  NOTICES. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any

at the address of such holder as shown on the registry books of the

                                       38



      SECTION 26.  SUPPLEMENTS AND AMENDMENTS.  Prior to the Distribution
Date, the Corporation and the Rights Agent shall, if the Corporation so
directs, supplement or amend any provision of this Agreement without the
approval of any holders of certificates representing shares of Common Stock or
Nonvoting Common Stock. From and after the Distribution Date, the Corporation
and the Rights Agent shall, if the Corporation so directs, supplement or amend
this Agreement without the approval of any holders of Right Certificates in
order (i) to cure any ambiguity, (ii) to correct or supplement any provision
contained herein which may be defective or inconsistent with any other
provisions herein, (iii) to shorten or lengthen any time period thereunder or
(iv) to change or supplement the provisions thereunder in any manner which the
Corporation may deem necessary or desirable and which shall not adversely
affect the interests of the holders of Right Certificates (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person);
provided, however, that this Agreement may not be supplemented or amended to
lengthen, pursuant to clause (iii) of this sentence, (A) a time period
relating to when the Rights may be redeemed at such time as the Rights are not
then redeemable or (B) any other time period unless such lengthening is for
the purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights. Upon the delivery of a certificate from an
appropriate officer of the Corporation which states that the proposed
supplement or amendment is in compliance with the terms of this Section 26,
the Rights Agent shall execute such supplement or amendment, provided that
such supplement or amendment does not adversely affect the rights or
obligations of the Rights Agent under Section 18 or Section 20 of this
Agreement. Prior to the Distribution Date, the interests of the holders of
Rights shall be deemed coincident with the interests of the holders of shares
of Common Stock and Nonvoting Common Stock.

      SECTION 27.  DETERMINATION AND ACTIONS BY THE BOARD OF DIRECTORS,
ETC.  The Board of Directors of the Corporation shall have the exclusive
power and authority to administer this Agreement and to exercise all rights
and powers specifically granted to the Board or the Corporation, 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, without limitation, a
determination to redeem or not redeem the Rights or to amend the Agreement and
whether any proposed amendment adversely affects the interests of the holders
of Right Certificates). For all purposes of this Agreement, any calculation of
the number of shares of Common Stock, Nonvoting Common Stock or other
securities outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common
Stock, Nonvoting Common Stock or any other securities of

                                       39



which any Person is the Beneficial Owner, shall be made in accordance with the
last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations
under the Exchange Act as in effect on the date of 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 Corporation, the Rights Agent, the holders of
the Right Certificates and all other parties and (y) not subject the Board to
any liability to the holders of the Right Certificates.

      SECTION 28.  SUCCESSORS.  All the covenants and provisions of this
Agreement by or for the benefit of the Corporation or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

      SECTION 29.  BENEFITS OF THIS AGREEMENT.  Nothing in this Agreement
shall be construed to give to any person or corporation other than the
Corporation, the Rights Agent and the registered holders of the Right
Certificates (and, prior to the Distribution Date, the shares of Common Stock
or Nonvoting 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 Corporation, the Rights Agent and the registered holders of the Right
Certificates (and, prior to the Distribution Date, the shares of Common Stock
or Nonvoting Common Stock).

      SECTION 30.  SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated.

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

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

                                       40



      SECTION 33.  DESCRIPTIVE HEADINGS.  Descriptive headings of the

    PARTICIPATING PREFERRED STOCK AND SERIES B PARTICIPATING PREFERRED STOCK

    1.   ISSUANCE.  The Board of Directors is authorized, subject to limitations
prescribed by law, to provide for the  issuance of shares of Preferred Stock  in
one  or more series,  to establish the number  of shares to  be included in each
such series, and to fix the designations, powers, preferences, and rights of the
shares of each such series, and any qualifications, limitations or  restrictions
thereof.

    2.  SERIES A PREFERRED STOCK AND SERIES B PREFERRED STOCK.

    Section 1.  DESIGNATION AND AMOUNT.  Eight million (8,000,000) shares of the
Preferred   Stock  of  the   Corporation  shall  be   designated  as  "Series  A
Participating Preferred  Stock,"  par  value  $.01  per  share  (the  "SERIES  A
PREFERRED  STOCK")  and  two  hundred fifty  thousand  (250,000)  shares  of the
Preferred  Stock  of  the   Corporation  shall  be   designated  as  "Series   B
Participating  Preferred  Stock,"  par  value  $.01  per  share  (the  "SERIES B
PREFERRED STOCK"). The number of shares  of each such series of Preferred  Stock
may  be increased or decreased by resolution of the Board of Directors; provided
that no decrease shall reduce the number  of shares of either of such series  of
Preferred  Stock to a  number less than that  of the shares  of such series then
outstanding plus  the number  of shares  issuable upon  exercise of  outstanding
rights,  options or warrants or upon conversion of outstanding securities issued
by the Corporation.

                                      A-1

    Section 2.  DIVIDENDS AND DISTRIBUTIONS.

    (A) Subject to the prior and superior rights of the holders of any shares of
stock of the Corporation ranking  prior and superior to  the shares of Series  A
Preferred  Stock and  Series B  Preferred Stock  with respect  to dividends, the
holders of shares of Series A Preferred Stock and Series B Preferred Stock shall
be entitled to receive, when, as and  if declared by the Board of Directors  out
of assets legally available for the purpose, quarterly dividends payable in cash
on the first business day of January, April, July and October in each year (each
such  date being  referred to  herein as  a "QUARTERLY  DIVIDEND PAYMENT DATE"),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share  or fraction  of a  share of  Series A  Preferred Stock  or Series  B
Preferred  Stock, in an amount per share  (rounded to the nearest cent) equal to
the greater  of  (a)  $1.00 or  (b)  subject  to the  provision  for  adjustment
hereinafter  set forth,  100 times  the aggregate per  share amount  of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends  or other  distributions  other than  a dividend  payable  in
shares  of Common  Stock or  a subdivision of  the outstanding  shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment  Date, or, with respect to  the
first  Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share  of Series A  Preferred Stock or  Series B Preferred  Stock;
provided  that no dividend shall be declared on the shares of Series A Preferred
Stock or Series B Preferred Stock unless at the same time a dividend is declared
on the outstanding shares of the other series in the same amount and having  the
same  record and payment dates.  In the event the  Corporation shall at any time
after September 1,  1993 (i)  declare any dividend  on Common  Stock payable  in
shares  of  Common Stock,  (ii) subdivide  the  outstanding Common  Stock, (iii)
combine the outstanding Common  Stock into a smaller  number of shares, or  (iv)
issue  any  shares  of Common  Stock  in  a reclassification  or  change  of the
outstanding shares  of  Common Stock  (including  any such  reclassification  or
change in connection with a merger in which the Corporation is the continuing or
surviving  Corporation), then in each  such case the amount  to which holders of
shares of Series A  Preferred Stock and Series  B Preferred Stock were  entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be  adjusted by multiplying such amount by a fraction, the numerator of which is
the number of shares  of Common Stock outstanding  immediately after such  event
and  the denominator of which is the number  of shares of Common Stock that were
outstanding immediately prior to such event.

    (B) The Corporation shall declare a dividend or distribution on the Series A
Preferred Stock and Series B Preferred Stock as provided in paragraph (A)  above
immediately  after it  declares a dividend  or distribution on  the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall  have been declared on the Common  Stock
during  the  period between  any Quarterly  Dividend Payment  Date and  the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series A Preferred  Stock and  Series B  Preferred Stock  shall nevertheless  be
payable on such subsequent Quarterly Dividend Payment Date.

    (C)  Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A  Preferred Stock  and Series B  Preferred Stock  from the  Quarterly
Dividend  Payment Date next preceding the date of issue of such shares of Series
A Preferred Stock or Series  B Preferred Stock, as the  case may be, unless  the
date of issue of such shares is prior to the record date for the first Quarterly
Dividend  Payment Date for such  shares, in which case  dividends on such shares
shall begin to accrue from the date of issue of such shares, or unless the  date
of issue is a Quarterly Dividend Payment Date or is a date after the record date
for the determination of holders of shares of Series A Preferred Stock or Series
B  Preferred  Stock entitled  to receive  a quarterly  dividend and  before such
Quarterly Dividend Payment Date, in either of which events such dividends  shall
begin  to accrue  and be cumulative  from such Quarterly  Dividend Payment Date.
Accrued but unpaid  dividends shall  not bear  interest. Dividends  paid on  the
shares  of Series A  Preferred Stock and  Series B Preferred  Stock in an amount
less than the total amount of such dividends at the time accrued and payable  on
such  shares shall  be allocated  pro rata on  a share-by-share  basis among all
shares of Series  A Preferred Stock  and Series  B Preferred Stock  at the  time
outstanding.   The  Board   of  Directors  may   fix  a  record   date  for  the

                                      A-2

determination of holders  of shares  of Series A  Preferred Stock  and Series  B
Preferred  Stock  entitled  to receive  payment  of a  dividend  or distribution
declared thereon, which record date shall be not more than 30 days prior to  the
date fixed for the payment thereof.

    Section  3.   VOTING RIGHTS.   The holders  of shares of  Series A Preferred
Stock and Series B Preferred Stock shall have the following voting rights:

    (A) (i) Except as provided in paragraph  C of this Section 3 and subject  to
the  provision  for adjustment  hereinafter set  forth, each  share of  Series A
Preferred Stock shall  entitle the holder  thereof to 100  votes on all  matters
submitted to a vote of the stockholders of the Corporation.

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

    (B) (i) Except  as  otherwise required  by applicable  law, each outstanding
share of Series B Preferred Stock shall not be entitled to vote on any matter on
which the stockholders of the Corporation shall be entitled to vote, and  shares
of  Series B Preferred Stock shall not  be included in determining the number of
shares voting or entitled to vote on any such matters.

       (ii) On any matter on which the holders  of shares  of Common  Stock  are
entitled  to vote and on which the holders of shares of Series B Preferred Stock
are also entitled to  vote, except as  otherwise required by  law, the Series  B
Preferred  Stock shall vote together with the Common Stock (and each other class
or series  of  capital stock  then  entitled to  vote  with the  Common  Stock);
provided  that each share of  Series B Preferred Stock  shall entitle the holder
thereof to 100 votes on any matter  on which the Series B Preferred Stock  shall
vote together with the Common Stock.

    (C)  (i) If, on  the date used  to determine stockholders  of record for any
meeting of stockholders for the election  of directors, a default in  preference
dividends (as defined in subparagraph (v) below) on the Series A Preferred Stock
shall  exist, the holders of the Series  A Preferred Stock shall have the right,
voting as  a  class  as described  in  subparagraph  (ii) below,  to  elect  two
directors  (in addition to the  directors elected by holders  of Common Stock of
the Corporation). Such right may be exercised (a) at any meeting of stockholders
for the election of directors  or (b) at a meeting  of the holders of shares  of
Voting  Preferred  Stock (as  hereinafter defined),  called  for the  purpose in
accordance with  the  Bylaws  of  the Corporation,  until  all  such  cumulative
dividends   (referred  to  above)  shall  have   been  paid  in  full  or  until
non-cumulative dividends have been paid regularly for at least one year.


    (ii) The right  of the  holders of  Series A  Preferred Stock  to elect  two
directors,  as described above, shall be  exercised as a class concurrently with
the rights of holders of any other series of any class of preferred stock of the
Corporation upon which voting rights to elect such directors have been conferred
and are then exercisable. The Series A Preferred Stock and any additional series
of such preferred stock  which the Corporation may  issue and which may  provide
for  the  right to  vote  with the  Series  A Preferred  Stock  are collectively
referred to herein as "VOTING PREFERRED STOCK."


   (iii) Each director  elected by  the holders  of shares  of Voting  Preferred
Stock  shall  be  referred to  herein  as  a "PREFERRED  DIRECTOR."  A Preferred
Director so elected shall continue to serve  as such director for a term of  one
year,  except that upon any  termination of the right of  all of such holders to
vote as a class for  Preferred Directors, the term  of office of such  directors
shall  terminate. Any  Preferred Director  may be removed  by, and  shall not be
removed except  by, the  vote of  the holders  of record  of a  majority of  the
outstanding  shares  of Voting  Preferred Stock  then entitled  to vote  for the
election of directors, present (in person or by proxy) and voting together as  a
single  class (a) at a meeting  of the stockholders, or (b)  at a meeting of the
holders of shares  of such Voting  Preferred Stock, called  for that purpose  in
accordance with the Bylaws of the Corporation.

   (iv)  So  long as  a  default in  any preference  dividends  on the  Series A
Preferred Stock  shall  exist or  the  holders of  any  other series  of  Voting
Preferred  Stock shall be entitled to elect Preferred Directors, (a) any vacancy
in the office of a Preferred Director  may be filled (except as provided in  the

                                      A-3

following clause  (b))  by an  instrument  in writing  signed  by the  remaining
Preferred  Director  and filed with the  Corporation and (b) in the  case of the
removal of any  Preferred Director, the vacancy may be filled by the vote of the
holders  of a majority  of the outstanding shares of Voting Preferred Stock then
entitled to vote for the election of directors, present  (in person or by proxy)
and  voting  together as a single  class,  at  such time as the removal shall be
effected.  Each  director  appointed  as  aforesaid  by  the remaining Preferred
Director shall be deemed, for all purposes hereof, to be a Preferred Director.

    (v) For purposes hereof, a "DEFAULT IN PREFERENCE DIVIDENDS" on the Series A
Preferred Stock  shall  be  deemed  to have  occurred  whenever  the  amount  of
cumulative  and  unpaid  dividends on  the  Series  A Preferred  Stock  shall be
equivalent to six full quarterly dividends or more (whether or not consecutive),
and, having so occurred, such default shall be deemed to exist thereafter until,
but only until, all cumulative dividends on all shares of the Series A Preferred
Stock then outstanding shall have been paid through the last Quarterly  Dividend
Payment  Date or until, but only  until, non-cumulative dividends have been paid
regularly for at least one year.

    (D) Except as set forth herein (or as otherwise required by applicable law),
holders of Series A Preferred Stock and  Series B Preferred Stock shall have  no
general  or special voting  rights and their  consent shall not  be required for
taking any corporate action.

    Section 4.  CERTAIN RESTRICTIONS.

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

    (i) declare or pay dividends, or make any other distributions, on any shares
of stock ranking junior (either as to dividends or upon liquidation, dissolution
or winding up) to the Series A Preferred Stock and Series B Preferred Stock;

    (ii)  declare  or pay  dividends, or  make any  other distributions,  on any
shares of stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or  winding up)  with the  Series  A Preferred  Stock and  Series  B
Preferred  Stock, except dividends paid ratably  on the Series A Preferred Stock
and Series B Preferred Stock  and all such parity  stock on which dividends  are
payable or in arrears in proportion to the total amounts to which the holders of
all  such  shares are  then entitled  (based  upon their  respective liquidation
values);

   (iii) redeem or purchase  or otherwise acquire  for consideration (except  as
provided  in  (iv) below)  shares  of any  stock  ranking junior  (either  as to
dividends or  upon liquidation,  dissolution  or winding  up)  to the  Series  A
Preferred  Stock and Series B Preferred Stock, provided that the Corporation may
at any time  redeem, purchase  or otherwise acquire  shares of  any such  junior
stock  in exchange  for shares  of any stock  of the  Corporation ranking junior
(both as to dividends  and upon dissolution, liquidation  or winding up) to  the
Series A Preferred Stock and Series B Preferred Stock;

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

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

                                      A-4

    Section  5.  REACQUIRED SHARES.   Any shares of  Series A Preferred Stock or
Series B Preferred Stock purchased or  otherwise acquired by the Corporation  in
any  manner  whatsoever  shall  be  retired  and  canceled  promptly  after  the
acquisition thereof.  All  such  shares shall  upon  their  cancellation  become
authorized but unissued shares of Preferred Stock and may be reissued as part of
a  new series of Preferred  Stock subject to the  conditions and restrictions on
issuance set forth in this Amended and Restated Certificate of Incorporation, in
any Certificate  of  Amendment  creating  a series  of  Preferred  Stock  or  as
otherwise required by law.

    Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

    (A)  Subject to the  prior and superior  rights of holders  of any shares of
stock of the Corporation ranking  prior and superior to  the shares of Series  A
Preferred  Stock  and  Series B  Preferred  Stock  with respect  to  rights upon
liquidation, dissolution or winding up (voluntary or otherwise), no distribution
shall be made to  the holders of  shares of stock ranking  junior (either as  to
dividends  or  upon liquidation,  dissolution  or winding  up)  to the  Series A
Preferred Stock and Series B Preferred Stock unless, prior thereto, the  holders
of  shares of Series A  Preferred Stock and Series  B Preferred Stock shall have
received $100.00 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such  payment
(the  "SERIES LIQUIDATION PREFERENCE"). Following the payment of the full amount
of the Series Liquidation Preference, no additional distributions shall be  made
to  the holders  of shares of  Series A  Preferred Stock and  Series B Preferred
Stock unless, prior thereto, the holders of shares of Common Stock and Nonvoting
Common Stock shall have received an amount per share (the "CAPITAL  ADJUSTMENT")
equal to the quotient obtained by dividing (i) the Series Liquidation Preference
by  (ii) 100 (subject to  the provision for adjustment  hereinafter set forth in
subparagraph (C) below) (such number  in clause (ii), the "ADJUSTMENT  NUMBER").
Following  the payment of  the full amount of  the Series Liquidation Preference
and the Capital  Adjustment in  respect of all  outstanding shares  of Series  A
Preferred  Stock and  Series B Preferred  Stock, and Common  Stock and Nonvoting
Common Stock, respectively,  holders of Series  A Preferred Stock  and Series  B
Preferred  Stock, and holders  of Common Stock and  Nonvoting Common Stock shall
receive their ratable  and proportionate  share of  the remaining  assets to  be
distributed  in the  ratio of the  Adjustment Number  to 1 with  respect to such
Series A Preferred  Stock and  Series B Preferred  Stock, and  Common Stock  and
Nonvoting Common Stock, on a per share basis, respectively.

    (B) In the event, however, that there are not sufficient assets available to
permit  payment in full of the Series Liquidation Preference and the liquidation
preferences of all other series of stock of the Corporation, if any, which  rank
on a parity with the Series A Preferred Stock and Series B Preferred Stock, then
such  remaining assets shall be  distributed ratably to the  holders of Series A
Preferred Stock and  Series B  Preferred Stock and  the holders  of such  parity
stock  in proportion to their respective  liquidation preferences. In the event,
however, that there  are not sufficient  assets available to  permit payment  in
full  of the Capital Adjustment, then such remaining assets shall be distributed
ratably to the holders of Common Stock and Nonvoting Common Stock.

    (C) In the event the Corporation shall  at any time after September 1,  1993
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide  the  outstanding  Common  Stock,  (iii)  combine  or  consolidate the
outstanding Common Stock  into a  smaller number of  shares, or  (iv) issue  any
shares  of Common  Stock in  a reclassification  or exchange  of the outstanding
shares of  Common Stock  (including  any such  reclassification or  exchange  in
connection with a merger in which the Corporation is the continuing or surviving
corporation), then in each such case the Adjustment Number in effect immediately
prior to such event shall be adjusted by multiplying such Adjustment Number by a
fraction  the  numerator  of which  is  the  number of  shares  of  Common Stock
outstanding immediately after  such event and  the denominator of  which is  the
number of shares of Common Stock that were outstanding immediately prior to such
event.

    Section 7.  CONVERSION

    (a)  CONVERSION OF SERIES A PREFERRED STOCK.  Subject to and upon compliance
with  the provisions  of Section 4  of Paragraph  B of this  Article FOURTH, any
Regulated Stockholder (as defined in

                                      A-5

Section 5 of Paragraph B of this  Article FOURTH) shall be entitled to  convert,
at  any  time and  from time  to time,  any  or all  of the  shares of  Series A
Preferred Stock  held by  such stockholder  into the  same number  of shares  of
Series B Preferred Stock.

    (b)  CONVERSION OF SERIES B PREFERRED STOCK.  Subject to and upon compliance
with  the provisions of  Section 4 of  Paragraph B of  this Article FOURTH, each
record holder of Series B Preferred Stock  shall be entitled to convert, at  any
time and from time to time, any or all of the shares of Series B Preferred Stock
held  by such stockholder into  the same number of  shares of Series A Preferred
Stock; PROVIDED HOWEVER, that  no holder of shares  of Series B Preferred  Stock
shall  be entitled to convert any such shares to the extent that, as a result of
such conversion, such  holder and  its Affiliates (as  defined in  Section 5  of
Paragraph  B of this Article FOURTH), directly or indirectly, would own, control
or have the power to vote a greater number of shares of Series A Preferred Stock
or other securities of any kind issued  by the Corporation than such holder  and
its  Affiliates shall be permitted  to own, control or  have power to vote under
any law, regulation, rule or other requirement of any governmental authority  at
the time applicable to such holder or its Affiliates.

    (c)   STOCK  SPLITS; ADJUSTMENTS.  If  the Corporation  shall in  any manner
subdivide (by stock split, stock dividend  or otherwise) or combine (by  reverse
stock  split or otherwise) the outstanding shares of Series A Preferred Stock or
Series B Preferred  Stock, then  the outstanding  shares of  Series B  Preferred
Stock  or Series A Preferred  Stock, as the case may  be, shall be subdivided or
combined, as the case  may be, to  the same extent, share  and share alike,  and
effective  provision shall be  made for the protection  of the conversion rights
hereunder.

    In the case of any reorganization,  reclassification or change of shares  of
Series A Preferred Stock or Series B Preferred Stock (other than a change in par
value  or from par to no par value as a result of a subdivision or combination),
or in case of any consolidation of the Corporation with one or more corporations
or  a  merger  of  the  Corporation  with  another  corporation  (other  than  a
consolidation  or merger in which the  Corporation is the resulting or surviving
corporation and  which does  not result  in any  reclassification or  change  of
outstanding  shares of  Series A Preferred  Stock or Series  B Preferred Stock),
each holder of a share of Series  A Preferred Stock or Series B Preferred  Stock
shall  have the right  at any time  thereafter, so long  as the conversion right
hereunder with respect to such share would exist had such event not occurred, to
convert such  share into  the  kind and  amount of  shares  of stock  and  other
securities  and properties (including cash) receivable upon such reorganization,
reclassification, change, consolidation or merger by  a holder of the number  of
shares  of Series A Preferred Stock or  Series B Preferred Stock into which such
shares of Series A Preferred Stock or Series B Preferred Stock, as the case  may
be,  might  have  been  converted  immediately  prior  to  such  reorganization,
reclassification, change,  consolidation  or merger.  In  the event  of  such  a
reorganization,  reclassification,  change, consolidation  or  merger, effective
provision shall be made in the certificate of incorporation of the resulting  or
surviving  corporation or otherwise for the  protection of the conversion rights
of the shares  of Series A  Preferred Stock  and Series B  Preferred Stock  that
shall be applicable, as nearly as reasonably may be, to any such other shares of
stock  and  other securities  and property  deliverable  upon conversion  of the
shares of Series A Preferred Stock or  Series B Preferred Stock into which  such
Series  B Preferred Stock or Series A Preferred Stock, as the case may be, might
have been converted immediately prior to such event.

    (d)  RESERVATION OF SHARES.  The Corporation shall at all times reserve  and
keep  available out of its authorized but  unissued shares of Preferred Stock or
its treasury shares, solely for the  purpose of issuance upon the conversion  of
shares  of Series A Preferred Stock and Series B Preferred Stock, such number of
shares of such class as are then issuable upon the conversion of all outstanding
shares of Series A Preferred Stock and Series B Preferred Stock.

    Shares of Series  A Preferred Stock  and Series B  Preferred Stock that  are
converted  into  shares  of another  class  shall  not be  reissued,  except for
reissuances in connection with  the conversion of shares  of Series A  Preferred
Stock held by Regulated Stockholders into shares of Series B Preferred Stock and
the  conversion of shares  of Series B  Preferred Stock into  shares of Series A
Preferred Stock.

                                      A-6

    Section 8.  CONSOLIDATION, MERGER, ETC.  In case the Corporation shall enter
into any consolidation, merger,  combination or other  transaction in which  the
shares  of  Common  Stock are  exchanged  for  or changed  into  other  stock or
securities, cash or any other property, then,  in any such case, (i) the  shares
of  Series A Preferred  Stock shall at  the same time  be similarly exchanged or
changed in an amount per share (subject to adjustment as set forth herein) equal
to 100  times the  aggregate amount  of  stock, securities,  cash or  any  other
property  (payable in kind),  as the case may  be, into which  or for which each
share of Common Stock is  changed or exchanged and (ii)  the shares of Series  B
Preferred  Stock shall at the same time  be similarly exchanged or changed in an
amount per share (subject to adjustment as set forth herein) equal to 100  times
the  aggregate amount of  stock, securities, cash or  other property (payable in
kind), as the case may be, into which or for which each share of Common Stock is
changed or  exchanged (or,  if any  shares of  Nonvoting Common  Stock are  then
outstanding  and are being exchanged or  changed, 100 times the aggregate amount
of stock, securities, cash or other property into which or for which each  share
of Nonvoting Common Stock is changed or exchanged).

    Section  9.   NO REDEMPTION.   The  shares of  Series A  Preferred Stock and
Series B Preferred Stock shall not be redeemable.

    Section 10.   RANKING.  The Series  A Preferred Stock and Series B Preferred
Stock  shall rank junior to all other  series of stock of the Corporation (other
than the Common Stock) as  to the payment of  dividends and the distribution  of
assets, unless the terms of any such series shall provide otherwise.

    Section 11.   AMENDMENT.    The   Amended   and   Restated   Certificate  of
Incorporation of the Corporation shall not be amended in any manner which  would
materially  alter or  change the  powers, preferences  or special  rights of any
series of Preferred Stock so as to affect them adversely without the affirmative
vote of the  holders of  a majority  or more of  the outstanding  shares of  all
series of Preferred Stock so affected, voting together as a separate class.
