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

         Effective September 30, 2006, Fuel Tech, Inc. (the "Company")
reincorporated in Delaware by filing a Certificate of Conversion and Certificate
of Incorporation with the Delaware Secretary of State. In connection with the
reincorporation in Delaware, the Company also adopted new Bylaws.

         The Certificate of Conversion, Certificate of Incorporation, and Bylaws
are filed as Exhibits 3.1, 3.2, and 3.3, respectively, to this current report,
and are incorporated herein by reference.

Item 5.05. Amendments to Registrant's Code of Ethics, or Waiver of a
           Provision of the Code of Ethics.

         Effective September 30, 2006 upon the domestication of the Registrant
as a Delaware corporation, the Board has adopted certain amendments to its Code
of Business Ethics and Conduct which, in amended form, is attached as Exhibit
14.1 to this Current Report on Form 8-K.

         The amendments were (a) the substitution of the name "Fuel Tech, Inc."
for the name "Fuel-Tech N.V.," (b) elimination of references to the Netherlands
Antilles, (c) the addition of a prohibition contained in the Employee Handbook
of the Company's operating subsidiary on purchases and sales or sales and
purchases of Fuel Tech common stock within any period of less than six months
and (d) the conformance of the definition of the "window period" for insider
trading to that contained in the Employee Handbook so that the window period is
now the period commencing with the opening of business on the third business day
after an earnings release and ending on the close of business of the last
business day of the following quarterly period rather than, as formerly, the
period ending on the close of business on the twelfth business day after the
earnings release.
