upon surrender of the Right Certificate, with the form of
election to purchase on the reverse side thereof duly executed,
to the Rights Agent at an office of the Rights Agent designated
for such purpose, together with an amount in cash, in lawful
money of the United States of America, by certified check or

11(d) hereof, as the case may be, together with an amount equal
to any applicable transfer tax required to be paid by the
holder of such Right Certificate in accordance with Section 9
hereof; provided, however, that after the later of the first
occurrence of a Triggering Event and the Distribution Date, in
lieu of the cash payment payable to the Company referred to in
this sentence, the registered holder of a Right Certificate
evidencing exercisable Rights (which shall not include Rights
that have become void pursuant to Section 11(a)(ii) hereof)
may, at its option, exercise the Rights evidenced thereby in
whole or in part in accordance with this Section 7(a) upon

                                       4

surrender of the Right Certificate as described above, together
with the election to exercise such Rights without payment of
cash on the reverse side thereof duly completed.  With respect

case may be, having a current per share market price
(determined pursuant to Section 11(e) hereof as of the date of
the first occurrence of any Triggering Event) equal to the
excess of (i) the aggregate current per share market price of
the Common Shares or other securities (determined pursuant to
Section 11(e) hereof as of the date of the first occurrence of
any Triggering Event) that would have been issuable upon
payment of the cash amount as described above over (ii) the
amount of cash that would have been payable to the Company upon
exercise absent such election."

adjustment from time to time as provided in Section 11 hereof."

11. To amend Section 7(c) to read in its entirety as follows:

    "(c) Subject to Sections 7(d), 11(a)(ii), and 11(d) hereof,
upon receipt of a Right Certificate representing exercisable
Rights with the form of election to purchase duly executed,
accompanied by either payment as described above or a duly
completed election to exercise without payment of cash, the
Rights Agent shall promptly (i) requisition from any transfer
agent of the Common Shares (or make available, if the Rights
Agent is the transfer agent) certificates representing the
number of whole Common Shares to be purchased and the Company
hereby irrevocably authorizes its transfer agent to comply with
all such requests, (ii) promptly after receipt of such
certificates, 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, (iii) if appropriate, requisition from the Company the
amount of cash to be paid or depository receipts to be issued
in lieu of the issuance of fractional shares in accordance with
Section 14 hereof or in lieu of the issuance of Common Shares
in accordance with Section 11(a)(iii) or 11(d) hereof, and (iv)
if appropriate, after receipt, promptly deliver such cash (or
depository receipts, when appropriate) to or upon the order of
the registered holder of such Right Certificate."

contrary, neither the Rights Agent nor the Company shall be
   5
                                       5

obligated to undertake any action with respect to any purported
transfer, split up, combination or exchange of any Right
Certificate pursuant to Section 6 hereof or exercise of a Right
Certificate as set forth in this Section 7 unless the
registered holder of such Right Certificate shall have
(i) completed and signed the certificate following the form of
assignment or the form of election to purchase, as applicable,
set forth on the reverse side of the Right Certificate
surrendered for such transfer, split up, combination, exchange
or exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner)
or Affiliates or Associates thereof as the Company shall have
reasonably requested."

13. To amend paragraph 3 of Section 9 to add at the end of the
parenthetical that reads "subject to payment of the Purchase
Price" the following:

         "if required"

14. To amend Section 9 to add the following at the end of
Section 9:

    "The Company further consents and agrees to use its best
efforts to (i) file on an appropriate form, as soon as
practicable following the later to occur of a Triggering Event
or the Distribution Date, a registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), with
respect to the securities issuable upon exercise of the Rights,
(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 Securities Act)
until the earliest of (A) the date as of which the Rights are
no longer exercisable for such securities, (B) the Expiration
Date, and (C) the Final Expiration Date.  The Company will also
take such action as may be appropriate under, or to ensure
compliance with, the securities or "blue sky" laws of the
various states in connection with the exercisability of the
Rights.  The Company may temporarily suspend the exercisability
of the Rights in order to prepare and file such registration
statement and permit it to become effective and upon any such
suspension, the Company will issue a public announcement
stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such
time as the suspension is no longer in effect.  Notwithstanding
anything in this Agreement to the contrary, the Rights shall
not be exercisable in any jurisdiction if the requisite
registration or qualification in such jurisdiction shall not
have been effected or the exercise of the Rights shall not be
permitted under applicable law.

    Notwithstanding anything in this Agreement to the contrary,
the Company covenants and agrees that, after the Distribution
   6
                                       6

Date, it will not, except as permitted by Section 23 or Section
26 hereof, take any action if at the time such action is taken
it is reasonably foreseeable that such action will diminish or
otherwise eliminate the benefits intended to be afforded by the
Rights.

    In the event that the Company is obligated to pay cash
and/or distribute other property pursuant to Sections 11, 13,
and 14 hereof, it will make all arrangements necessary so that
such cash and/or property are available for distribution by the
Rights Agent, if and when appropriate."

15. To amend the first sentence of Section 10 to add at the end
of the clause that reads "payment of the Purchase Price" the
following:

         "if required"

16. To amend clause (C) of Section 11(a)(ii) to add at the end
of clause C of Section 11(a)(ii) the following:

"; provided, however, that a Person shall not be deemed to have
become the Beneficial Owner of 20% or more of the Common Shares
then outstanding for the purposes of this Section 11(a)(ii)(C)
solely as a result of a reduction in the number of Common
Shares outstanding unless and until such time as (1) such
Person or any Affiliate or Associate of such Person shall
thereafter become the Beneficial Owner of any additional Common
Shares other than as a result of a stock dividend, stock split
or similar transaction effected by the Company in which all
holders of Common Shares are treated equally, or (2) any other
Person who is the Beneficial Owner of any Common Shares shall
thereafter become an Affiliate or Associate of such Person,"

17. To amend Section 11(a)(ii) by deleting the language
following Section 11(a)(ii) (C) (as amended pursuant to item 16
of this Amendment) in its entirety and replacing such language
with the following:

"then, and in each such case, the Company shall make
adjustments in the terms of the Rights so that each holder of a
Right, except as provided below, shall thereafter have a right
to receive, upon exercise thereof in accordance with the terms
of this Agreement, at an exercise price per Right equal to the
product of two times the then-current Purchase Price multiplied
by the number of Common Shares for which a Right was
exercisable immediately prior to the first occurrence of a
Triggering Event, such number of Common Shares as shall equal
the result obtained by (x) multiplying the product of two times
the then-current Purchase Price by the number of Common Shares
for which a Right was exercisable immediately prior to the
first occurrence of a Triggering Event and dividing that
product by (y) 50% of the current per share market price of the
   7
                                       7

Common Shares (determined pursuant to Section 11(e) hereof) on
the date of the first occurrence of a Triggering Event.
Notwithstanding anything in this Agreement to the contrary,
from and after the later of the Distribution Date and the first
occurrence of a Flip-In Event, (1) any Rights that are or were
acquired or beneficially owned by any Acquiring Person (or any
Affiliate or Associate of such Acquiring Person) shall be void
and any holder of such Rights shall thereafter have no right to
exercise such Rights under any provision of this Agreement,
(2) no Right Certificate shall be issued pursuant to this
Agreement that represents Rights that are beneficially owned by
an Acquiring Person or any Affiliate or Associate thereof,
(3) no Right Certificate shall be issued at any time upon the
transfer of any Rights to an Acquiring Person or any Affiliate
or Associate thereof or to any nominee of such Acquiring Person
or Affiliate or Associate thereof, and (4) any Right
Certificate delivered to the Rights Agent for transfer to an
Acquiring Person or any Affiliate or Associate thereof shall be
cancelled.  Notwithstanding anything to the contrary set forth
herein, the provisions of this Section 11(a)(ii) shall not
apply to any Permitted Transaction."

18. To amend Section 11(a)(iii) to read in its entirety as
follows:

      "(iii) Upon the occurrence of a Flip-In Event, if
    there shall not be sufficient authorized but unissued
    Common Shares or authorized and issued Common Shares held
    in treasury to permit the exercise in full of the Rights in
    accordance with the foregoing subsection (ii), the
    Directors of the Company shall use their best efforts
    promptly to authorize and, subject to the provisions of
    Section 9 hereof, make available for issuance additional
    Common Shares; provided, however, that if at any time after
    90 calendar days after the first occurrence of a Flip-In
    Event, there shall not be sufficient Common Shares
    available for issuance upon the exercise of a Right, then
    the Company shall deliver, upon the surrender of such Right
    and without requiring payment of the Purchase Price, Common
    Shares (to the extent available), and then cash (to the
    extent permitted by applicable law and any agreements or
    instruments to which the Company is a party in effect
    immediately prior to the first occurrence of any Flip-In
    Event), which Common Shares and cash shall have an
    aggregate value equal to the excess of (x) the aggregate
    current per share market price (determined pursuant to
    Section 11(e) hereof) of all the Common Shares issuable in
    accordance with subsection (ii) of this Section 11(a) upon
    the exercise of a Right over (y) the product of the
    then-current Purchase Price multiplied by the number of
    Common Shares for which a Right was exercisable immediately
    prior to the first occurrence of a Triggering Event.  To
    the extent that any legal or contractual restrictions
   8
                                       8

    prevent the Company from paying the full amount of cash
    payable in accordance with the foregoing sentence, the
    Company shall pay to holders of the Rights as to which such
    payments are being made all amounts which are not then
    restricted on a pro rata basis.  The Company shall continue
    to make payments on a pro rata basis as funds become
    available until such payments have been paid in full."

19. To amend Section 11(d) to read in its entirety as follows:

        "(d) In the event that, following the Share
    Acquisition Date, directly or indirectly:

            (i)   the Company shall consolidate with, or merge
        with or into, any other Person and the Company shall
        not be the continuing or surviving corporation of such
        merger or consolidation; or

          (ii)    any Person shall consolidate with the
        Company, or merge with or into the Company and the
        Company shall be the continuing or surviving
        corporation of such merger or consolidation and, in
        connection with such merger or consolidation, all or
        part of the Common Shares shall be changed into or
        exchanged for stock or other securities of any other
        Person or cash or any other property; or

          (iii)   the Company shall sell or otherwise transfer
        (or one or more of its Subsidiaries shall sell or
        otherwise transfer), in one or more transactions,
        assets or earning power (including, without
        limitation, securities creating any obligation on the
        part of the Company and/or any of its Subsidiaries)
        representing in the aggregate more than 50% of the
        assets or earning power of the Company and its
        Subsidiaries (taken as a whole) to any Person or
        Persons;

    then, and in each such case, proper provision shall be made
    so that (A) each holder of a Right (except as otherwise
    provided herein) shall thereafter have the right to
    receive, upon the exercise thereof in accordance with the
    terms of this Agreement at an exercise price per Right
    equal to the product of two (2) times the then-current
    Purchase Price multiplied by the number of Common Shares
    for which a Right was exercisable immediately prior to the
    first occurrence of a Triggering Event, such number of
    validly authorized and issued, fully paid, nonassessable
    and freely tradeable Common Shares of the Issuer (as such
    term is hereinafter defined), free and clear of any liens,
    encumbrances and other adverse claims and not subject to
    any rights of call or first refusal, as shall be equal to
    the result obtained by (x) multiplying the product of two
   9
                                       9

    (2) times the then-current Purchase Price by the number of
    Common Shares for which a Right is exercisable immediately
    prior to the first occurrence of a Triggering Event and
    dividing that product by (y) 50% of the current per share
    market price of the Common Shares of the Issuer (determined
    pursuant to Section 11(e) hereof), on the date of
    consummation of such Flip-Over Event; (B) the Issuer shall
    thereafter be liable for, and shall assume, by virtue of
    the consummation of such Flip-Over Event, all the
    obligations and duties of the Company pursuant to this
    Agreement; (C) the term "Company" shall thereafter be
    deemed to refer to the Issuer; and (D) the Issuer shall
    take such steps (including, without limitation, the
    reservation of a sufficient number of its Common Shares to
    permit the exercise of all outstanding Rights) in
    connection with such consummation as may be necessary to
    assure that the provisions hereof shall thereafter be
    applicable, as nearly as reasonably may be possible, in
    relation to its Common Shares thereafter deliverable upon
    the exercise of the Rights.  For purposes of this
    Section 11(d), "Issuer" shall mean (A) in the case of any
    Flip-Over Event described in Sections 11(d)(i) or (ii)
    above, the Person that is the continuing, surviving,
    resulting or acquiring Person (including the Company as the
    continuing or surviving corporation of a transaction
    described in Section 11(d)(ii) above), and (B) in the case
    of any Flip-Over Event described in Section 11(d)(iii)
    above, the Person that is the party receiving the greatest
    portion of the assets or earning power (including, without
    limitation, securities creating any obligation on the part
    of the Company and/or any of its Subsidiaries) transferred
    pursuant to such transaction or transactions; provided,
    however, that, in any such case, (x) if (1) no class of
    equity security of such Person is, at the time of such
    merger, consolidation or transaction and has been
    continuously over the preceding 12-month period, registered
    pursuant to Section 12 of the Exchange Act, and (2) such
    Person is a Subsidiary, directly or indirectly, of another
    Person, a class of equity security of which is and has been
    so registered, the term "Issuer" shall mean such other
    Person; and (y) in case such Person is a Subsidiary,
    directly or indirectly, of more than one Person, a class of
    equity security of two or more of which are and have been
    so registered, the term "Issuer" shall mean whichever of
    such Persons is the issuer of the equity security having
    the greatest aggregate market value.  Notwithstanding the
    foregoing, if the Issuer in any of the Flip-Over Events
    listed above is not a corporation or other legal entity
    having outstanding equity securities, then, and in each
    such case, (A) if the Issuer is directly or indirectly
    wholly owned by a corporation or other legal entity having
    outstanding equity securities, then all references to
    Common Shares of the Issuer shall be deemed to be
   10
                                       10

references to the Common Shares of the corporation or other
legal entity having outstanding equity securities which
ultimately controls the Issuer, and (B) if there is no such
corporation or other legal entity having outstanding equity
securities, (1) proper provision shall be made so that the
Issuer shall create or otherwise make available for
purposes of the exercise of the Rights in accordance with
the terms of this Agreement, a kind or kinds of security or
securities having a fair market value at least equal to the
economic value of the Common Shares which each holder of a
Right would have been entitled to receive if the Issuer had
been a corporation or other legal entity having outstanding
equity securities; and (2) all other provisions of this
Agreement shall apply to the issuer of such securities as
if such securities were Common Shares.  The Company shall
not consummate any Flip-Over Event unless the Issuer shall
have a sufficient number of authorized Common Shares (or
other securities as contemplated above) which have not been
issued or reserved for issuance to permit the exercise in
full of the Rights in accordance with this Section 11(d),
and unless prior to such consummation the Company and the
Issuer shall have executed and delivered to the Rights
Agent a supplemental agreement providing for the terms set
forth in Section 11(d) and further providing that as
promptly as practicable after the consummation of any
Flip-Over Event, the Issuer shall:

          (A) prepare and file a registration statement
     under the Securities Act, with respect to the Rights
     and the securities issuable upon exercise of the
     Rights on an appropriate form, and shall use its best
     efforts to cause such registration statement to
     (1) become effective as soon as practicable after such
     filing and (2) remain effective (with a prospectus at
     all times meeting the requirements of the Securities
     Act) until the earlier of the Expiration Date and the
     Final Expiration Date;

          (B) take all such action as may be appropriate
     under, or to ensure compliance with, the securities or
     "blue sky" laws of the various states in connection
     with the exercisability of the Rights; and

          (C) deliver to holders of the Rights historical
     financial statements for the Issuer and each of its
     Affiliates which comply in all respects with the
     requirements for registration on Form 10 (or any
     successor form) under the Exchange Act.

The provisions of this Section 11(d) shall similarly apply
to successive mergers or consolidations or sales or other
transfers.  In the event that a Flip-Over Event occurs at
any time after the occurrence of a Flip-In Event, the
   11
                                       11

    Rights which have not theretofore been exercised shall
    thereafter become exercisable in the manner described in
    this Section 11(d).

         In the event that the Company shall be the continuing
    or surviving corporation in a merger or consolidation
    referred to in subparagraph (ii) above and Common Shares of
    the Company are required to be issued upon exercise of the
    Rights following such merger or consolidation, and if there
    shall not be sufficient authorized but unissued Common
    Shares or authorized and issued Common Shares held in
    treasury to permit the exercise in full of the Rights in
    accordance with the foregoing, the Directors of the Company
    shall use their best efforts promptly to authorize and,
    subject to the provisions of Section 9 hereof, make
    available for issuance additional Common Shares; provided,
    however, that if at any time after 90 calendar days after
    the first occurrence of a Flip-In Event, there shall not be
    sufficient Common Shares available for issuance upon the
    exercise of a Right, then the Company shall deliver, upon
    the surrender of such Right and without requiring payment
    of the Purchase Price, Common Shares (to the extent
    available), and then cash (to the extent permitted by
    applicable law and any agreements or instruments to which
    the Company is a party in effect immediately prior to the
    first occurrence of any Flip-In Event), which Common Shares
    and cash shall have an aggregate value equal to the excess
    of (x) the aggregate current per share market price
    (determined pursuant to Section 11(e) hereof) of all the
    Common Shares issuable in accordance with this Section
    11(d) upon the exercise of a Right over (y) the product of
    the then-current Purchase Price multiplied by the number of
    Common Shares for which a Right was exercisable immediately
    prior to the occurrence of the merger or consolidation
    referred to in subparagraph (ii) above.  To the extent that
    any legal or contractual restrictions prevent the Company
    from paying the full amount of cash payable in accordance
    with the foregoing sentence, the Company shall pay to
    holders of the Rights as to which such payments are being
    made all amounts which are not then restricted on a pro
    rata basis.  The Company shall continue to make payments on
    a pro rata basis as funds become available until such
    payments have been paid in full."

20. To amend Section 11(o) to replace the clause "shares of
Common Stock" with the following:

         "Common Shares"

21. To add new Section 11(p) to read in its entirety as follows:.

         "(p) Notwithstanding the provisions of Sections 11(a)
    (ii) and 11(d) hereof, the Directors of the Company may, at
   12
                                       12

their option, at any time after the later of the
Distribution Date and the first occurrence of a Triggering
Event, exchange all or part of the then-outstanding and
exercisable Rights (which shall not include Rights that
have become void pursuant to the provisions of
Section 11(a)(ii) hereof) for Common Shares at an exchange
ratio of one Common Share per Right, appropriately adjusted
to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such exchange
ratio being hereinafter referred to as the "Exchange
Ratio").  Notwithstanding the foregoing, the Directors of
the Company shall not be empowered to effect such exchange
at any time after any Person (other than the Company or any
Subsidiary or any employee benefit plan of the Company or
of any Subsidiary or any entity holding Common Shares for
or pursuant to the terms of any such plan) together with
all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the Common Shares then
outstanding.  Immediately upon the action of the Directors
of the Company ordering the exchange of any Rights pursuant
to this Section 11(p), and without any further action and
without any notice, the right to exercise such Rights shall
terminate and the only right with respect to such Rights
thereafter of the holder of such Rights shall be to receive
that number of Common Shares equal to the number of such
Rights held by such holder multiplied by the Exchange
Ratio.  Promptly after the action of the Directors of the
Company ordering the exchange of any Rights pursuant to
this Section 11(p), the Company shall publicly announce
such action, and within 10 calendar days thereafter shall
give notice of any such exchange to all of the holders of
such Rights at their last addresses as they appear upon the
registry books of the Rights Agent; provided, however, that
the failure to give, or any defect in, such notice shall
not affect the validity of such exchange.  Any notice which
is mailed in the manner herein provided shall be deemed
given, whether or not the holder receives the notice.  Each
such notice of exchange shall state the method by which the
exchange of the Common Shares for Rights will be effected
and, in the event of any partial exchange, the number of
Rights which will be exchanged.  Any partial exchange shall
be effected pro rata based on the number of Rights (other
than Rights which have become void pursuant to the
provisions of Section 11(a)(ii)) held by each holder of
Rights.  In any exchange pursuant to this Section 11(p),
the Company, at its option, may substitute for any Common
Share exchangeable for a Right, (i) cash, (ii) debt
securities of the Company, (iii) other assets, or (iv) any
combination of the foregoing, in any event having an
aggregate value which the Directors of the Company shall
have determined in good faith to be equal to the current
per share market price of one Common Share (determined
pursuant to Section 11(e) hereof) on the Trading Day
   13
                                       13

    immediately preceding the date of exchange pursuant to this
    Section 11(p).  The Company shall not be required to issue
    fractions of Common Shares or to distribute certificates
    which evidence fractional Common Shares upon the exchange
    of a Right.  In lieu of such fractional Common Shares, the
    Company shall pay to the registered holders of the Right
    Certificates with regard to which such fractional Common
    Shares would otherwise be issuable an amount in cash equal
    to the same fraction of the current per share market price
    of a whole Common Share (determined pursuant to Section
    11(e) hereof) on the Trading Day immediately preceding the
    date of exchange pursuant to this Section 11(p)."

22. To amend Section 17 to add at the end of the first sentence
thereof the following:

    "or exchanged pursuant to the provisions of Section 11(p)
    hereof"

23. To amend Section 23(a) to read in its entirety as follows:

         "(a)    Prior to the earlier of the Expiration Date and
    the Final Expiration Date, the Directors of the Company
    may, at their option, redeem all but not less than all of
    the then-outstanding Rights at the Redemption Price at any
    time prior to the Close of business on the later of (i) the
    Distribution Date and (ii) the Share Acquisition Date."

24. To delete Sections 23(b) and 23(f) in their entirety, and
to renumber Sections 23(c), 23(d) and 23(e) as Sections 23(b),
23(c) and 23(d), respectively.

25. To delete the last two sentences of Section 23(c) (as
renumbered by item 24 of this Amendment) and to add at the end
of Section 23(c) the following:

    "; provided, however, that the failure to give, or any
    defect in, any such notice shall not affect the validity of
    the redemption of the Rights.  Any notice which is mailed
    in the manner herein provided shall be deemed given,
    whether or not the holder receives the notice.  The notice
    of redemption mailed to the holders of Rights shall state
    the method by which the payment of the Redemption Price
    will be made.  The Company may, at its option, pay the
    Redemption Price in cash, Common Shares (based upon the
    current per share market price of the Common Shares
    (determined pursuant to Section 11(e) hereof) at the time
    of redemption) or any other form of consideration deemed
    appropriate by the Directors of the Company (based upon the
    fair market value of such other consideration, determined
    by the Directors of the Company in good faith) or any
    combination thereof."
   14
                                                                              14

26. To amend Section 23(d) (as renumbered by item 24 of this
Amendment) to replace the clause "paragraphs (a) or (b) above,
or both," with the following:

    "paragraph (a) above"

27. The form of Right Certificate attached as Exhibit A to the
Rights Agreement and the form of Summary of Rights attached as
Exhibit B to the Rights Agreement are hereby amended to reflect
the provisions of this Amendment.

28. This Amendment is effective as of October 28, 1991, and all
references to the Rights Agreement shall, as of such date, be
deemed to be references to the Rights Agreement, as amended by
this Amendment.
