distinguish it from other series;

          (ii)  The number of shares included in such series, which number

Corporation;

          (vi)  The price or prices (cash or otherwise) at which, the period or

of such series may be purchased, redeemed or acquired (by exchange or
otherwise), in whole or in part;

          (vii)  Provision or provisions, if any, for the Corporation to

or provisions;

shares of such series not inconsistent with applicable law.

          B.  Except as may from time-to-time be required by law and except as
otherwise may be provided by the Board of Directors in accordance with paragraph
A of this Article 4 in respect of any particular series of Preferred Stock, all
voting rights of the Corporation shall be vested exclusively in the holders of

Corporation may be adopted, amended or repealed by the Board of Directors of the
Corporation by the vote of a majority of the entire Board of Directors at a
meeting of the board at which a quorum is present.

          SEVENTH.  No holder of shares of the Corporation of any class, now or
hereafter authorized, shall have any preferential or preemptive right to
subscribe for, purchase or receive any shares of the corporation of any class,
now or hereafter authorized, or any options or warrants for such shares, or any
rights to subscribe for or purchase such shares, or any securities convertible
into or exchangeable for such shares, which may at any time be issued, sold or
offered for sale by the Corporation.

          EIGHTH.  Subject to the rights, if any, of holders of any class or
series of Preferred Stock, now or hereafter authorized, special meetings of
shareholders may be called only by the Chairman of the Board or by the Board of
Directors pursuant to resolution adopted by a majority of the total number of
directors which the Corporation would have if there were no vacancies.

          NINTH.  The following provisions shall relate to the Board of
Directors of the Corporation:

          A.  The size of the Board of Directors shall be fixed by or pursuant
to the By-laws.  The Board of Directors shall be divided into three classes
designated Class I, Class II and Class III.  Such classes shall be as nearly
equal in number as the then total number of directors constituting the entire
Board permits.  At the first annual meeting of shareholders, or any special
meeting in lieu thereof, Class I, Class II and Class III directors shall be
elected for terms expiring at the next succeeding annual meeting, the second
succeeding annual meeting and the third succeeding annual meeting, respectively,
and until their respective successors are elected and qualified.  At each annual
meeting of shareholders after such first annual (or special) meeting of
shareholders, the directors chosen to succeed those in the class whose terms
then expire shall be elected by shareholders for terms expiring at the third
succeeding annual meeting after election, or for such lesser term for which one
or more may be nominated in a particular case in order to assure that the number
of directors in each class shall be appropriately constituted and until their
respective successors are elected and qualified.  Newly created directorships or
any decrease in directorships resulting from increases or decreases in the
number of directors shall be so apportioned among the classes of directors as to
make all the classes as nearly equal in number as possible.  Vacancies on the
Board of Directors at any time for any reason except the removal of directors
without cause may be filled by a majority of the directors then in office,
although less than a quorum.  If the number of directors is increased by the
Board of Directors and any newly created directorships are filled by the Board,
there shall, to the extent required by New York law, be no classification of the
additional directors until the next annual meeting of shareholders.

          Notwithstanding the foregoing, whenever the holders of any one or more
classes or series of Preferred Stock, now or hereafter authorized, shall have
the right, voting separately or by class or series, to elect directors at an
annual or special meeting of shareholders, the election, term of office, filling
of vacancies and other features of such directorships shall be governed by any
provisions of the Certificate of Incorporation applicable thereto, and such
directors so elected shall not be divided into one or more classes pursuant to
this Article 9A unless expressly provided by such provisions.

          B.  Directors may be removed for cause by a vote of shareholders
entitled to vote thereon.  Directors shall not be removed without cause by
shareholders, except in the case of a director elected by the holders of any
class or series of Preferred Stock, now or hereafter authorized, voting as a
class or series, when so entitled by the provisions of the Certificate of
Incorporation applicable thereto.

          TENTH.  In addition to any vote that may be required by law or in the
Certificate of Incorporation in respect of any class or series of Preferred
Stock, now or hereafter authorized, the provisions of Articles 6, 7, 8, 9, 10,
11 and 12 of the Certificate of Incorporation shall not be amended or repealed,
or a new provision adopted inconsistent therewith, without the affirmative vote
of not less than two-thirds of the shares entitled to vote thereon at such
annual or special meeting of shareholders at which any such action is proposed.

          ELEVENTH.  Except as otherwise provided in the Certificate of
Incorporation in respect of any class or series of Preferred Stock, now or
hereafter authorized, the By-laws of the corporation may be amended or repealed,
or new By-laws may be adopted, either (a) by a vote of shareholders entitled to
vote at any annual or special meeting of shareholders, or (b) by a vote of the
majority of the entire Board of Directors at any regular or special meeting of
directors; provided, however, that any amendment or repeal of, or the adoption
of any new By-law or provision inconsistent with, Article I (Sections 1.2, 1.13
or 1.14), Article II (Sections 2.2, 2.3, or 2.7) or Article VI (Sections 6.6 or
6.7) of the By-laws, if by action of such shareholders, shall be only upon the
affirmative vote of not less than two-thirds of the shares entitled to vote
thereon at such annual or special meeting shareholders at which any such action
is proposed and, if by action of the Board of Directors, shall be only upon the
approval of not less than two-thirds of the entire Board of Directors at any
regular or special meeting of directors.

          TWELFTH.  Except as may be provided by the Board of Directors in
accordance with paragraph A of Article 4 of respect of any particular series of
Preferred Stock, any action required or permitted to be taken by the
shareholders of the Corporation must be taken at a duly called annual or special
meeting of such holders and may not be taken by any consent in writing by such
holders.  Except as otherwise provided for herein or required by law, special
meetings of shareholders of the corporation for any purpose or purposes may be
called only by the Chairman of the Board, the President or the Board of
Directors pursuant to a resolution stating the purpose or purposes thereof, and
any power of shareholders to call a special meeting is specifically denied.

          THIRTEENTH.  A director of the Corporation shall not be personally
liable to the Corporation or its shareholders for damages for any breach of duty
as a director, except to the extent that such exemption from liability or
limitation thereof is not permitted under the Business Corporation Law as
currently in effect or as it may hereafter be amended.  No amendment,
modification or repeal of this Article THIRTEENTH shall adversely affect any
right or protection of a director that exists at the time of such amendment,
modification or repeal.

          FOURTEENTH.  The foregoing restated Certificate of Incorporation was
authorized by the Board of Directors of the Corporation by unanimous written
consent dated February 5, 1999, followed by written consent of the sole
shareholder dated February 5, 1999.



          IN WITNESS WHEREOF, the undersigned have signed this restated
Certificate of Incorporation on February 5, 1999 and affirm the statements
contained herein as true under the penalties of perjury.
