ITEM 4.  DESCRIPTION OF SECURITIES

         Not applicable. The class of securities to be offered is registered
under Section 12 of the Exchange Act.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Charles W. Grinnell, Esq. is furnishing an opinion required for this
registration statement as to the legality of the securities to be issued under
the Plan. Mr. Grinnell is an officer, director and employee of the Registrant
and has 50,000 outstanding options to purchase shares of Common Stock of the
Registrant.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Under Section 145 of the Delaware General Corporation Law, a
corporation may indemnify a director, officer, employee or agent of the
corporation (or a person who is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise) against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by the person if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. In the case of an action brought by or in the
right of a corporation, the corporation may indemnify a director, officer,
employee or agent of the corporation (or a person who is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise) against
expenses (including attorneys' fees) actually and reasonably incurred by him if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, except that no indemnification
may be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent a court finds that, in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses as the
court shall deem proper.

         Fuel Tech Inc.'s certificate of incorporation provides that no director
of Fuel Tech, Inc. shall be liable to Fuel Tech, Inc. or its stockholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by law.

         Fuel Tech, Inc.'s certificate of incorporation also provides that Fuel
Tech, Inc. shall indemnify to the fullest extent permitted by Delaware law any
and all of its directors and officers, or former directors and officers, or any
person who may have served at Fuel Tech, Inc.'s request as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise.

ITEM 9.  UNDERTAKINGS

         The undersigned Registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement; and

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

                  Provided, however, that clauses (1)(i) and (1)(ii) shall not
apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in periodic reports filed with or furnished to
the Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Act that are incorporated by reference in this registration statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the General Corporation Law of the State of Delaware,
Fuel Tech, Inc.'s Certificate of Incorporation and By-Laws, as amended, or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in such Securities
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than payment by the registrant
of expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in such Securities Act and will be governed
by the final adjudication of such issue.

         Charles W. Grinnell, Esq. is furnishing an opinion required for this

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Under Section 145 of the Delaware General Corporation Law, a
corporation may indemnify a director, officer, employee or agent of the
corporation (or a person who is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise) against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by the person if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. In the case of an action brought by or in the
right of a corporation, the corporation may indemnify a director, officer,
employee or agent of the corporation (or a person who is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise) against
expenses (including attorneys' fees) actually and reasonably incurred by him if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, except that no indemnification
may be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent a court finds that, in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses as the
court shall deem proper.

         Fuel Tech Inc.'s certificate of incorporation provides that no director
of Fuel Tech, Inc. shall be liable to Fuel Tech, Inc. or its stockholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by law.

         Fuel Tech, Inc.'s certificate of incorporation also provides that Fuel
Tech, Inc. shall indemnify to the fullest extent permitted by Delaware law any
and all of its directors and officers, or former directors and officers, or any
person who may have served at Fuel Tech, Inc.'s request as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise.

ITEM 9.  UNDERTAKINGS

         The undersigned Registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement; and

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

                  Provided, however, that clauses (1)(i) and (1)(ii) shall not
apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in periodic reports filed with or furnished to
the Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Act that are incorporated by reference in this registration statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the General Corporation Law of the State of Delaware,
Fuel Tech, Inc.'s Certificate of Incorporation and By-Laws, as amended, or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in such Securities
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than payment by the registrant
of expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in such Securities Act and will be governed
by the final adjudication of such issue.

                                       5
