                                    EXHIBIT A

         TENTH. This Article is inserted for the management of the business and
for the conduct of the affairs of the Corporation.

         1. Number of Directors. The number of directors of the Corporation
shall not be less than three. The exact number of directors within the
limitations specified in the preceding sentence shall be fixed from time to time
by, or in the manner provided in, the Corporation's By-laws.

         2. Classes of Directors. The Board of Directors shall be and is divided
into three classes: Class I, Class II and Class III. No one class shall have
more than one director more than any other class. If a fraction is contained in
the quotient arrived at by dividing the designated number of directors by three,
then, if such fraction is one-third, the extra director shall be a member of
Class III, and if such fraction is two-thirds, one of the extra directors shall
be a member of Class II and one of the extra directors shall be a member of
Class III, unless otherwise provided from time to time by resolution adopted by
the Board of Directors.

         3. Election of Directors. Elections of directors need not be by written
ballot except as and to the extent provided in the By-laws of the Corporation.

         4. Terms of Office. Each director shall serve for a term ending on the
date of the third annual meeting following the annual meeting at which such
director was elected; provided, that each initial director in Class I shall
serve for a term ending on the date of the annual meeting in 2000; each initial
director in Class II shall serve for a term ending on the date of the annual
meeting in 2001; and each initial director in Class III shall serve for a term
ending on the date of the annual meeting in the year 2002; and provided further,
that the term of each director shall be subject to the election and
qualification of his successor and to his earlier death, resignation or removal.

         5. Allocation of Directors Among Classes in the Event of Increases or
Decreases in the Number of Directors. In the event of any increase or decrease
in the authorized number of directors, (i) each director then serving as such
shall nevertheless continue as a director of the class of which he is a member
and (ii) the newly created or eliminated directorships resulting from such
increase or decrease shall be apportioned by the Board of Directors among the
three classes of directors so as to ensure that no one class has more than one
director more than any other class. To the extent possible, consistent with the
foregoing rule, any newly created directorships shall be added to those classes
whose terms of office are to expire at the latest dates following such
allocation, and any newly eliminated directorships shall be subtracted from
those classes whose terms of offices are to expire at the earliest dates
following such allocation, unless otherwise provided from time to time by
resolution adopted by the Board of Directors.
   4
         6. Quorum; Action at Meeting. A majority of the directors at any time
in office shall constitute a quorum for the transaction of business. In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each director so
disqualified, provided that in no case shall less than one-third of the number
of directors fixed pursuant to Section 1 above constitute a quorum. If at any
meeting of the Board of Directors there shall be less than such a quorum, a
majority of those present may adjourn the meeting from time to time. Every act
or decision done or made by a majority of the directors present at a meeting
duly held at which a quorum is present shall be regarded as the act of the Board
of Directors unless a greater number is required by law, by the Bylaws of the
Corporation or by this Certificate of Incorporation.

         7. Removal. Directors of the Corporation may be removed only for cause
by the affirmative vote of the holders of at least two-thirds of the shares of
the capital stock of the Corporation issued and outstanding and entitled to
vote.

         8. Vacancies. Any vacancy in the Board of Directors, however occurring,
including a vacancy resulting from an enlargement of the size of the Board of
Directors, shall be filled only by a vote of a majority of the directors then in
office, although less than a quorum, or by a sole remaining director. A director
elected to fill a vacancy shall be elected to hold office until the next
election of the class for which such director shall have been chosen, subject to
the election and qualification of his successor and to his earlier death,
resignation or removal.

         9. Stockholder Nominations and Introduction of Business, Etc. Advance
notice of stockholder nominations for election of directors and other business
to be brought by stockholders before a meeting of stockholders shall be given in
the manner provided by the By-laws of the Corporation.

         10. Amendments to Article. Notwithstanding any other provisions of law,
this Certificate of Incorporation or the By-laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least sixty-six and two-thirds percent
(66 2/3%) of the shares of capital stock of the Corporation issued and
outstanding and entitled to vote shall be required to amend or repeal, or to
adopt any provision inconsistent with, this Article TENTH.

         ELEVENTH. Stockholders of the Corporation may not take any action by
written consent in lieu of a meeting. Notwithstanding any other provisions of
law, this Certificate of Incorporation or the By-laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least sixty-six and two-thirds percent
(66 2/3%) of the shares of capital stock of the Corporation issued and
outstanding and entitled to vote shall be required to amend or repeal, or to
adopt any provision inconsistent with, this Article ELEVENTH.
   5
         TWELFTH. Special meetings of stockholders may be called at any time by
only the Chairman of the Board of Directors, the President or the Board of
Directors. Business transacted at any special meeting of stockholders shall be
limited to matters relating to the purpose or purposes stated in the notice of
meeting. Notwithstanding any other provision of law, this Certificate of
Incorporation or the By-laws of the Corporation, and notwithstanding the fact
that a lesser percentage may be specified by law, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66 2/3%) of the shares of
capital stock of the Corporation issued and outstanding and entitled to vote
shall be required to amend or repeal, or to adopt any provision inconsistent
with, this Article TWELFTH.
