                                   ARTICLE XI

         Subject to the rights of the holders of any particular class or series
of preferred stock or preference stock of this Corporation:

         A. The number of directors of this Corporation shall be fixed from time
to time by a resolution adopted by not less than 80% of the directors then in
office. The directors shall be divided into three classes, as nearly equal in
number as possible, with the term of office of the first class to expire at the
1999 Annual Meeting of shareholders, the term of office of the second class to
expire at the 2000 Annual Meeting of shareholders and the term of office of the
third class to expire at the 2001 Annual Meeting of shareholders. At each Annual
Meeting of shareholders following such initial classification and election, the
class of directors whose terms of office shall expire at such time shall be
elected to hold office for terms expiring at the third succeeding Annual Meeting
of shareholders following their election. Each director shall hold office until
his successor shall be elected and shall qualify.

         B. (i) Newly created directorships resulting from any increase in the
total number of authorized directors may be filled by the affirmative vote of
not less than 80% of the directors then in office, or by a sole remaining
director, at any regular or special meeting of the Board of Directors, or by the
shareholders in accordance with the By-Laws, and (ii) any vacancies on the Board
of Directors resulting from death, resignation, retirement, disqualification,
removal from office or other cause may be filled only by the affirmative vote of
not less than 80% of the directors then in office, or by a sole remaining
director, at any regular or special meeting of the Board of Directors. If the
number of directors is increased or decreased, any increase or decrease shall be
apportioned as nearly as possible among each class so as to maintain the number
of directors in each class as nearly equal as possible, and any additional
director of any class elected to fill any vacancy resulting from any increase in
such class shall hold office for a term which shall coincide with the remaining
term of that class. No decrease in the total number of authorized directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

         C. Any director may be removed only for cause and only by the
affirmative vote of the holders of not less than a majority of the voting power
of the then outstanding shares of capital stock of the Corporation entitled to
vote generally in the election of directors, voting together as a single class,
at any regular or special meeting of the shareholders.

of preferred stock or preference stock of this Corporation:

         A. Except as provided in Article X and this Article XII of the Articles
of Incorporation, the Articles of Incorporation of this Corporation shall be
subject to alteration, amendment or repeal, and new provisions thereof may be
adopted, by the affirmative vote of the holders of not less than a majority of
the voting power of the then outstanding shares of capital stock entitled to
vote generally in the election of directors (the "Voting Stock"), voting
together as a single class. Notwithstanding the foregoing and notwithstanding
any other provisions of these Articles of Incorporation or the By-Laws of the
Corporation and in addition to any other requirements of applicable law, the
alteration, amendment or repeal of, or the adoption of any provision
inconsistent with Article X or this Article XII of the Articles of Incorporation
shall require the affirmative vote of the holders of not less than two-thirds
(2/3) of the Voting Stock, voting together as a single class.

         B. No amendment, alteration, repeal or adoption of any new provision of
the Articles of Incorporation shall be made which permits action required or
permitted to be taken by shareholders to be taken by written consent by less
than all of the holders of Voting Stock unless such amendment, alteration,
repeal or adoption of such new provision of the Articles of Incorporation shall
have been approved by the affirmative vote of the holders of not less than
two-thirds (2/3) of the Voting Stock, voting together as a single class.

         C. The By-Laws of this Corporation shall be subject to alteration,
amendment or repeal, and new By-Laws may be adopted, (i) by the affirmative vote
of the holders of not less than a majority of the Voting Stock, voting together
as a single class, or (ii) by the affirmative vote of not less than a majority
of the members of the Board of Directors then in office; provided, that any
alternation, amendment or repeal, or the adoption of any provision inconsistent
with Article II, Section 2 or Section 4, or Article III, Section 2, Section 3,
Section 6, or Section 11, or Article XII or Article XIII of the By-Laws shall
require, in the case of shareholder action, the affirmative vote of the holders
of not less than two thirds (2/3) of the Voting Stock, voting together as a
single class, or, in the case of action by the Board of Directors, the
affirmative vote of such number of directors constituting not less than 80% of
the directors then in office, or by the sole remaining director, at any regular
or special meeting of the Board of Directors.
