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

Effective October 13, 2005, by written consent, the Board of Directors of the
Company amended Article II, Section 10 of the Company's Amended and Restated
Bylaws ("Bylaws") to delete the second paragraph of Section 10.  The language in
that paragraph implied that the Company's shares have cumulative voting rights,
while the Company's Amended & Restated Articles of Incorporation clearly state
that they do not and would preempt any inconsistent language in the Bylaws.  The
Board amended the Bylaws to delete the inconsistent language.
