EXHIBIT A TO STATEMENT WITH RESPECT TO SHARES



RESOLVED, that pursuant and subject to the provisions of Article 5 of the
Articles of Incorporation of the Corporation, as amended, there is hereby established a class of Preferred Stock to which the following provisions shall be applicable:



Class A Junior Participating Preferred Stock



Section 1. Designation. The class shall be designated as Class A Junior Participating Preferred Stock
(hereinafter this Class).



Section 2.
Number. The number of shares of this Class authorized to be issued is 151,000. Such number may be increased or decreased by resolution of the Board of Directors; provided, however, that no decrease shall reduce the number of
shares of this Class to a number less than that of the shares then outstanding.



Section 3. Dividends and Distributions.



(A) Subject to the prior and superior rights of the holders of any shares of any class or series of Preferred Stock ranking prior and superior to this Class with respect to dividends, the holders of shares of this
Class shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available therefor, quarterly dividends payable in cash on the 15th 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 this Class, 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, par value $.15625 per
share, of the Corporation (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
this Class. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount to which holders of shares of this Class 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 this Class as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided, however, 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 this Class shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.



19 of 24



---

(C) Dividends shall begin to accrue and be cumulative on outstanding shares of this Class
from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of this Class, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date with respect to this Class, 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 this
Class 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 this Class in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares
at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of this Class entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 60
days prior to the date fixed for the payment thereof.



Section
4. Liquidation, Dissolution or Winding Up. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation (a Liquidation), no distribution shall be made (x) to the holders of Common Stock or
any other shares of stock ranking junior (either as to dividends or upon Liquidation) to this Class unless, prior thereto, the holders of shares of this Class shall have received an amount per share equal to the greater of (i) $100, plus an amount
equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, or (ii) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate amount to be distributed per share
to holders of Common Stock or (y) to the holders of stock ranking on a parity (either as to dividends or upon Liquidation) with this Class, except distributions made ratably on this Class and all other such parity stock in proportion to the total
amounts to which the holders of all such shares are entitled upon such Liquidation. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of this Class were entitled immediately prior to such event under clause (ii) of clause (x) 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.



For purposes of this Statement, the voluntary sale, lease, exchange or
transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation to, or a consolidation or merger of the Corporation with, one or more corporations shall not be deemed
to be a Liquidation.



Section 5. Redemption. The shares
of this Class shall not be redeemable.



Section 6. Voting
Rights. The holders of shares of this Class shall have the following voting rights:



(A) Subject to the provision for adjustment hereinafter set forth, each share of this Class shall entitle the holder thereof to 100 votes
on all matters submitted to a vote of the Common shareholders of the Corporation. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination of the outstanding shares of Common



20 of 24



---

Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock,
then in each such case the number of votes per share to which holders of shares of this Class were entitled immediately prior to such event shall be adjusted by multiplying such 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.



(B) Except as otherwise provided herein, in the Articles of Incorporation of the Corporation or by law, the
holders of shares of this Class and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of Common shareholders of the Corporation.



(C) (i) If at any time dividends on any shares of this Class shall be in arrears in an amount equal to six
full quarterly dividends thereon, the holders of this Class and all other classes and/or series of Preferred Stock (in each case to the extent then entitled pursuant to the terms of such classes or series), voting together as one class, shall have
the exclusive and special right to elect two directors of the Corporation, and the number of directors constituting the Board of Directors of the Corporation shall be increased by two (if not previously increased in connection with the right of
other classes or series of Preferred Stock entitled to vote together with this Class to elect directors of the Corporation) for such purpose and, if necessary, the By-laws of the Corporation shall be deemed amended to so provide.



(ii) Whenever any such right of the holders of this Class
shall have vested, such right may be exercised initially either at a special meeting of the holders of this Class and all other classes and/or series so entitled to vote, if any, called as hereinafter provided, or at any annual meeting of
shareholders, and thereafter at annual meetings of shareholders. The right of the holders of this Class voting separately as a class with such other classes and/or series to elect members of the Board of Directors of the Corporation as aforesaid
shall continue until such time as all dividends accrued on all shares of this Class shall have been paid in full, or declared and set apart for payment, at which time the special right of the holders of this Class so to vote separately as a class
with such other classes and/or series for the election of directors shall terminate, subject to revesting in the event of each and every subsequent occurrence of an arrearage specified in subparagraph (C)(i) above.



(iii) At any time when such special voting power shall have
vested in the holders of this Class as provided in the preceding subparagraph (C)(i), the proper officer of the Corporation shall, upon the written request of the holders of record of at least 10% of the then outstanding voting power of shares of
this Class and all other classes and/or series entitled to vote in the election of such directors addressed to the Secretary of the Corporation, call a special meeting of the holders of this Class for the purpose of electing directors pursuant to
this paragraph (C). Such meeting shall be held at the earliest practicable date. If such meeting shall not be called by the proper officer of the Corporation within 20 days after personal service of such written request upon the Secretary of the
Corporation, or within 20 days after mailing the same within the United States of America, by registered mail addressed to the Secretary of the Corporation at its principal office, then the holders of record of at least 10% of the then outstanding
voting power of shares of this Class and all other classes and/or series entitled to



21 of 24



---

vote in the election of such directors may designate in writing one of their number to call such meeting at the expense of the Corporation, and such meeting
may be called by such person so designated by giving the notice required for annual meetings of shareholders. Any holder of this Class so designated shall have access to the stock books of the Corporation for the purpose of causing meetings of
shareholders to be called pursuant to these provisions. Notwithstanding the provisions of this subparagraph (C)(iii), no such special meeting shall be called during the period within 90 days immediately preceding the date fixed for the next annual
meeting of shareholders.



(iv) At any meeting
held for the purpose of electing directors at which the holders of this Class and any other classes and/or series of Preferred Stock shall have the special right to elect directors as provided in this paragraph (C), the presence, in person or by
proxy, of the holders of 50% of the voting power of the then outstanding aggregate number of shares of this Class and such other classes and/or series shall be required to constitute a quorum for the election of any director by the holders of such
classes and/or series. At any such meeting or adjournment thereof, (a) the absence of a quorum shall not prevent the election of directors other than those to be elected by all such classes and/or series of Preferred Stock voting separately as a
class, and the absence of a quorum for the election of such other directors shall not prevent the election of the directors to be elected by this Class and any other classes and/or series of Preferred Stock that may be voting with it separately as a
class, and (b) in the absence of either or both such quorums, the holders of a majority of the voting power of the shares present in person or by proxy of the stock or stocks which lack a quorum shall have power to adjourn the meeting for the
election of directors whom they are entitled to elect from time to time without notice other than announcement at the meeting until a quorum shall be present.



(v) During any period when the holders of this Class have the right to vote separately as a class for directors as provided in this
paragraph (C), (1) the directors so elected by the holders of the one or more classes and/or series of Preferred Stock entitled to vote for such directors shall continue in office until the next succeeding annual meeting or until their successors,
if any, are elected by such holders and qualify or, until termination of the right of the holders of the one or more classes and/or series of Preferred Stock entitled to vote for such directors to vote separately as a class for directors as provided
in this paragraph (C) and (2) vacancies in the Board of Directors shall be filled only by vote of a majority (even if that be only a single director) of the remaining directors theretofore elected by the holders of the one or more classes and/or
series of Preferred Stock which elected the directors whose office shall have become vacant or, if there be no such remaining director, directors to fill such vacancies shall be elected by the holders of the one or more classes and/or series of
Preferred Stock entitled to vote for such directors at a special meeting called pursuant to the provisions of this paragraph (C). Immediately upon any termination of the right of the holders of this Class and any other classes and/or series of
Preferred Stock to vote separately as a class for directors as provided in this paragraph (C), the term of office of the directors then in office so elected by the holders of this Class and any such other classes and/or series shall terminate.
Whenever the term of office of the directors so elected by the holders of this Class and any such other classes and/or series shall terminate and the special voting power vested in the holders of this Class and any such other



22 of 24



---

classes and/or series as provided in this paragraph (C) shall have terminated, the number of directors shall be such number as may be provided for in the
by-laws irrespective of any increase made pursuant to the provisions of this paragraph (C).



(D) So long as any shares of this Class are outstanding, the Corporation shall not, without the consent of the holders of two-thirds of

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 and/or any other property, then in any such case the shares of this Class shall at the same time be
similarly exchanged for or changed into an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after October 6, 2003 declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the
amount set forth in the preceding sentence with respect to the exchange or change of shares of this Class shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.



Section 9. Ranking. This Class shall rank junior to all other classes and series of the Corporations Preferred Stock as to the payment of
dividends and the distribution of assets upon Liquidation, unless the terms of any such class or series shall provide otherwise.



Section 10. Fractional Shares. This Class may be issued in fractions of a share which shall entitle the holder, in proportion to such holders
fractional shares, to exercise voting rights, receive dividends, participate in distributions and have the benefit of all other rights of holders of this Class.



Section 11. Other Rights. The holders of shares of this Class shall not have any other preferences or special rights.
