Item 5.03   Amendments to Articles of Incorporation or Bylaws;
Change in Fiscal Year.

On May 6, 2009, the board of directors (the "Board") of the
Company adopted and approved, effective immediately,
amendments to the By-Laws of the Company (as amended, the
"Amended By-Laws").  The amendments added to the existing By-
Laws, among other things, procedures to propose
business or nominations for election of directors to be
considered at annual or special meetings, which are referred
to as "advance notice provisions."  The advanced notice
provisions of the Amended By-Laws, among other things:

-  require shareholders to provide advance notice of
   shareholder proposals or nominations of directors at an
   annual meeting, and such advance notice must be delivered
   to the principal executive office of the Company not later
   than 90 days nor earlier than 120 days prior to the first
   anniversary of the preceding year's annual meeting, subject
   to certain conditions;

-  require shareholders to provide advance notice of
   nominations of directors at a special meeting at which
   directors are to be elected, and such advance notice must
   be delivered to the principal executive office of the
   Company not later than 90 days nor earlier than 120 days
   prior to the special meeting or within 10 days following
   the public announcement of the special meeting and the
   nominees proposed by the Board to be elected at the special
   meeting;

-  provide that the procedures and requirement set forth in
   the advance notice provisions are the only means for
   business to come before a shareholder meeting, other than
   matters properly brought under Rule 14a-8 of the Securities
   Exchange Act of 1934, as amended (the "Exchange Act"); and

-  provide that persons are not eligible to serve as directors
   if not nominated in accordance with the advance notice
   provisions or appointed by the Board to fill a vacancy.

In addition to adding the advance notice provisions, the
Amended By-Laws also amends the Company's existing By-Laws to,
among other things:

-  revise the requirements for calling a special meeting of
   shareholders;

-  revise the circumstances under which a shareholder meeting
   may be adjourned;

-  provide rules regarding the conduct of shareholder
   meetings; and

-  make other technical amendments.

A copy of the Amended By-Laws is attached hereto as Exhibit
3.1 and incorporated herein by reference. The foregoing
description of the Amended By-Laws is qualified in its
entirety by reference to the full text of the Amended By-Laws.
