meeting by the holders of shares entitled to vote thereon.

     Section 7.     Record Date.  The Board may prescribe a

     Section 11.    Notice of Stockholder Business and
                     Nominations.

          (a)  Annual Meetings of Stockholders.

               (i)  Nominations of persons for election as 
directors and the proposal of business to be considered by 
the stockholders may be made at an annual meeting of 
stockholders (A) pursuant to the Corporation's notice of 
meeting, (B) by or at the direction of the Board or (C) by 
any stockholder who was a stockholder of record at the time 
of giving of notice provided for in this By-law, who is 
entitled to vote at the meeting and who complies with the 
notice procedures set forth in this By-law.

               (ii)  For nominations or other business to be 
properly brought before an annual meeting by a stockholder 
pursuant to clause (C) of paragraph (a)(i) of this By-law, 
the stockholder must have given timely notice thereof in 
writing to the Secretary and such other business must 
otherwise be a proper matter for stockholder action.  To be 
timely, a stockholder's notice shall be delivered to the 
Secretary at the principal executive offices of the 
Corporation not later than the close of business on the 90th 
day nor earlier than the close of business on the 120th day 
prior to the first anniversary of the preceding year's 
annual meeting; provided, however, that in the event that 
the date of the annual meeting is more than 30 days before 
or more than 60 days after such anniversary date, notice by 
the stockholder to be timely must be so delivered not 
earlier than the close of business on the 120th day prior to 
such annual meeting and not later than the close of business 
on the later of the 90th day prior to such annual meeting or 
the 10th day following the day on which public announcement 
of the date of such meeting is first made by the 
Corporation.  In no event shall the public announcement of 
an adjournment of an annual meeting commence a new time 
period for the giving of a stockholder's notice as described 
above.  Such stockholder's notice shall set forth: (A) as to 
each person whom the stockholder proposes to nominate for 
election or reelection as a director all information 
relating to such person that is required to be disclosed in 
solicitations of proxies for election of directors in an 
election contest, or is otherwise required, in each case 
pursuant to Regulation 14A under the Securities Exchange Act 
of 1934, as amended (the "Exchange Act"), and Rule 14a-11 
thereunder (including such person's written consent to being 
named in the proxy statement as a nominee and to serving as 
a director if elected); (B) as to any other business that 
the stockholder proposes to bring before the meeting, a 
brief description of the business desired to be brought 
before the meeting, the reasons for conducting such business 
at the meeting and any material interest in such business of 
such stockholder and the beneficial owner, if any, on whose 
behalf the proposal is made; and (C) as to the stockholder 
giving the notice and the beneficial owner, if any, on whose 
behalf the nomination or proposal is made (x) the name and 
address of such stockholder, as they appear on the 
Corporation's books, and of such beneficial owner and (y) 
the class and number of shares of the Corporation which are 
owned beneficially and of record by such stockholder and 
such beneficial owner.

               (iii)  Notwithstanding anything in the second 
sentence of paragraph (a)(ii) of this By-law, in the event 
that the number of directors to be elected to the Board is 
increased and the public announcement by the Corporation 
naming all of the nominees for director or specifying the 
size of the increased Board occurs less than 100 days prior 
to the first anniversary of the preceding year's annual 
meeting, a stockholder's notice required by this By-law 
shall also be considered timely, but only with respect to 
nominees for any new positions created by such increase, if 
it shall be delivered to the Secretary at the principal 
executive offices of the Corporation not later than the 
close of business on the 10th day following the day on which 
such public announcement is first made.

          (b)  Special Meetings of Stockholders.

           Nominations of persons for election as directors 
may be made at a special meeting of stockholders at which 
directors are to be elected pursuant to the Corporation's 
notice of meeting (i) by or at the direction of the Board or 
(ii) provided that the Board has determined that directors 
shall be elected at such meeting, by any stockholder of the 
Corporation who is a stockholder of record at the time of 
giving of notice provided for in this By-law, who shall be 
entitled to vote at the meeting and who complies with the 
notice procedures set forth in this By-law.  In the event 
the Corporation calls a special meeting of stockholders for 
the purpose of electing one or more directors to the Board, 
any such stockholder may nominate a person or persons (as 
the case may be), for election to such position(s) as are 
specified in the Corporation's notice of meeting, if the 
stockholder's notice required by paragraph (a)(ii) of this 
By-law shall be delivered to the Secretary at the principal 
executive offices of the Corporation not earlier than the 
close of business on the 120th day prior to such special 
meeting and not later than the close of business on the 
later of the 90th day prior to such special meeting or the 
10th day following the day on which public announcement is 
first made of the date of the special meeting and of the 
nominees proposed by the Board to be elected at such 
meeting.  In no event shall the public announcement of an 
adjournment of a special meeting commence a new time period 
for the giving of a stockholder's notice as described above.

          (c)  General.

               (i) Only such persons who are nominated in 
accordance with the procedures set forth in this By-law 
shall be eligible to serve as directors and only such 
business shall be conducted at a meeting of stockholders as 
shall have been brought before the meeting in accordance 
with the procedures set forth in this By-law.  The Chairman 
of the meeting shall have the power and duty to determine 
whether a nomination or any business proposed to be brought 
before the meeting was made or proposed, as the case may be, 
in accordance with the procedures set forth in this By-law 
and, if any proposed nomination or business is not in 
compliance with this By-law, to declare that such defective 
proposal or nomination shall be disregarded.

               (ii)  For purposes of this By-law, "public 
announcement" shall mean disclosure in a press release 
reported by the Dow Jones News Service, Associated Press or 
comparable national news service or in a document publicly 
filed by the Corporation with the Securities and Exchange 
Commission pursuant to Section 13, 14 or 15(d) of the 
Exchange Act.

               (iii)  Notwithstanding the foregoing 
provisions of this By-law, a stockholder shall also comply 
with all applicable requirements of the Exchange Act and the 
rules and regulations thereunder with respect to the matters 
set forth in this By-law.  Nothing in this By-law shall be 
deemed to affect any rights (A) of stockholders to request 
inclusion of proposals in the Corporation's proxy statement 
pursuant to Rule 14a-8 under the Exchange Act or (B) of the 
holders of any series of Preferred Stock to elect directors 
under the circumstances specified by the terms of such 
Preferred Stock.

                         ARTICLE V

                      Indemnification

     The Corporation shall, to the fullest extent permitted 
by law, indemnify each of its past, present and future 
directors, officers and employees and their heirs, executors 
and administrators (collectively, the "indemnitees") for any 
and all costs and expenses resulting from or relating to any 
suit or claim arising out of, or alleged to arise out of, 
past or future service to the Corporation or to another 
corporation, partnership, joint venture, trust, employee 
benefit plan or other enterprise at the Corporation's 
request.

     Without limiting the generality of the foregoing, (i) 
the costs and expenses for which each indemnitee shall, as a 
matter of right, be entitled to indemnification shall 
include all costs and expenses incurred by the indemnitee in 
the defense or settlement of, or in the satisfaction of any 
order or judgment entered in, any suit or claim (including 
any suit or claim brought or alleged to be brought in the 
right of the Corporation to procure a judgment in its favor) 
arising out of, or alleged to arise out of, any act or 
failure to act by the indemnitee as a director, officer or 
employee of, or in any service to, the Corporation or to 
another corporation, partnership, joint venture, trust, 
employee benefit plan or other enterprise at the 
Corporation's request, (ii) the stockholders or the Board of 
the Corporation are authorized to, by a resolution of the 
stockholders or the Board, as the case may be, indemnify the 
indemnitees for costs and expenses, and (iii) the 
Corporation may, to the extent authorized by resolution of 
the Board or the stockholders, enter into agreements with 
indemnitees to indemnify them for costs and expenses; 
provided, however, that no indemnification may be made to or 
on behalf of any director, officer, employee or other 
indemnitee if a judgment or other final adjudication adverse 
to the director, officer, employee or other indemnitee 
establishes that his acts were committed in bad faith or 
were the result of active and deliberate dishonesty and were 
material to the cause of action so adjudicated, or that he 
personally gained in fact a financial profit or other 
advantage to which he was not legally entitled, and provided 
further that the foregoing proviso shall prohibit such 
indemnification only to the extent that such indemnification 
is prohibited by Sec. 721 of the New York Business 
Corporation Law.

     As used in this Article V,

          (a)  "costs and expenses" means any and all costs, 
expenses and liabilities incurred by an indemnitee, 
including but not limited to (i) attorney's fees, (ii) 
amounts paid in settlement of, or in the satisfaction of any 
order or judgment in, any suit or claim and (iii) fines, 
penalties and assessments asserted or adjudged in any suit 
or claim.

          (b)  "suit or claim" means any and all suits, 
claims, actions, investigations or proceedings, and threats 
thereof, whether civil, criminal or administrative, 
heretofore or hereafter instituted or asserted.
