                                    EXHIBIT A

Article 12. Board of Directors.

      Section 12.1 Power of the Board of Directors. The business and affairs of
the Corporation shall be managed by or under the direction of its Board of
Directors. In furtherance, and not in limitation, of the powers conferred by the
laws of the State of Delaware, the Board of Directors is expressly authorized
to:

      (a) adopt, amend, alter, change or repeal the Bylaws of the Corporation;
provided, however, that no Bylaws hereafter adopted shall invalidate any prior
act of the directors that would have been valid if such new Bylaws had not been
adopted;

      (b) determine the rights, powers, duties, rules and procedures that affect
the power of the Board of Directors to manage and direct the business and
affairs of the Corporation, including the power to designate and empower
committees of the Board of Directors, to elect, appoint and empower the officers
and other agents of the Corporation, and to determine the time and place of, and
the notice requirements for, Board meetings, as well as quorum and voting
requirements for, and the manner of taking, Board action; and

      (c) exercise all such powers and do all such acts as may be exercised or
done by the Corporation, subject to the provisions of the laws of the State of
Delaware, this Certificate of Incorporation, and the Bylaws of the Corporation.

      Section 12.2 Number of Directors. The number of directors constituting the
Board of Directors shall be as specified in the Bylaws.

      Section 12.3 Classified Board of Directors. The directors shall be divided
into three classes, with each class to be as nearly equal in number as
reasonably possible, and with the term of office of the first class of directors
to expire at the 1995 Annual Meeting of the Stockholders, the term of office of
the second class of directors to expire at the 1996 Annual Meeting of
Stockholders and the term of office of the third class of directors to expire at
the 1997 Annual Meeting of Stockholders. Commencing with the 1995 Annual Meeting
of Stockholders, directors elected to succeed those directors whose terms have
thereupon expired shall be elected for a term of office to expire at the third
succeeding Annual Meeting of Stockholders after their election, and upon the
election and qualification of their successors. If the number of directors is
changed, any increase or decrease shall be apportioned among the classes so as
to maintain or attain, if possible, the number of directors in each class as
nearly equal as reasonably possible, but in no case will a decrease in the
number of directors shorten the term of any incumbent director.

      Section 12.4 Vacancies. Any vacancies in the Board of Directors for any
reason and any newly created directorships resulting by reason of any increase
in the number of directors may be filled only by the Board of Directors, acting
by a majority of the remaining directors then in office, although less than a
quorum, or by a sole remaining director, and any directors so appointed shall
hold office until the election of the class for which such directors have been
chosen and until their successors are elected and qualified.

      Section 12.5 Removal of Directors. Except as may be provided in a
resolution or resolutions providing for any class or series of Preferred Stock
pursuant to article 4 of the Certificate of Incorporation, as amended, of the
Corporation with respect to any directors elected by the holders of such class
or series, any director or the entire Board of Directors, may be removed from
office at any time, but only for cause and only by the affirmative vote of the
holders of a majority of the voting power of all of the shares of capital stock
of the Corporation then entitled to vote generally in the election of directors,
voting together as a single class.

      Section 12.6 Amendment of Bylaws. The Board of Directors shall have the
power to adopt, amend, alter, change and repeal any Bylaws of the Corporation,
but such right of the directors shall not divest or limit the right of the
stockholders to alter, amend, and repeal the Bylaws.

approved by the Board of Directors. The three proposed amendments were presented
for approval by the stockholders at the annual meeting held on July 22, 1994.
The amendments relating to the establishment of classifications of directors and
the addition of a new article 12 were found not to have been properly adopted by

                 Certificate of Incorporation of the Corporation be amended by
                 changing article numbered 4 thereof so that, as amended, said
                 article 4 shall be and read as follows:

                     "4. The total number of shares of stock which the
                 corporation shall have authority to issue is forty-six million
                 (46,000,000), consisting of forty-five million (45,000,000)
                 shares of Common Stock, $.01 par value per share, and one
                 million (1,000,000) shares of Preferred Stock, $.01 par value

                 Thousand and 00/100 Dollars ($460,000.00).

                     The designations and powers, the rights and preferences and
                 the qualifications, limitations or restrictions with respect to
                 each class of stock of the Corporation shall be as determined
                 by the Board of Directors from time to time."

     SECOND: That all other provisions contained in said Certificate of
Amendment are ratified, confirmed and approved in all respects as of the date
hereof.

     IN WITNESS WHEREOF, the undersigned hereby make this certificate, hereby
declaring and certifying that this is their act and deed and that the facts
stated herein are true, and accordingly have hereunto set their hands this
20th day of December 1994.
