SECTION 5 - CORPORATE GOVERNANCE AND MANAGEMENT

Item 5.03 Amendments to Articles of Incorporation or Bylaws.

The Board of Directors of the Registrant adopted an amendment to Registrant's
Amended and Restated Bylaws, effective on June 26, 2006. The following first
sentence contained under Article II, Section 7, was deleted:

            "Each director shall be elected by the affirmative vote of the
      holders of a majority of the votes entitled to be cast thereon."

Effective June 26, 2006, the first sentence of Article II, Section 7 is hereby
superseded and replaced with the following sentence: (The entire paragraph is
restated for your convenience).

            "SECTION 7. Voting. Each director shall be elected by the
      affirmative vote of the holders of a majority of the votes entitled to be
      cast thereon; provided, that, at any time prior to the Corporation's 2007
      annual meeting of stockholders, the Board of Directors shall have the
      power, in its sole discretion, to call a special meeting for the election
      of the directors of the class that was previously elected at the
      Corporation's 2003 annual meeting of stockholders, and such other business
      as the Board of Directors may determine, and at such special meeting, such
      directors shall be elected by a plurality of the votes validly cast
      thereon. Subject to the rights of the holders of preferred stock, each
      share may be voted for as many individuals as there are directors to be
      elected and for whose election the share is entitled to be voted. A
      majority of the votes cast at a meeting of stockholders duly called and at
      which a quorum is present shall be sufficient to approve any other matter
      which may properly come before the meeting, unless more than a majority of
      the votes cast is required by statute or by the charter of the
      Corporation. Unless otherwise provided in the charter, each outstanding
      share, regardless of class, shall be entitled to one vote on each matter
      submitted to a vote at a meeting of stockholders."
