Please see the text below under the captions "Certain Relationships and
Related Transactions -- Relationship with Fuel Tech; Conflicts of Interest" for
information concerning the election of Messrs. Ralph and Douglas Bailey to the
Board of Fuel-Tech N.V., a 27.4 % owner of common shares of the Company.

Mr. Eric N. Balles, formerly Vice President-Technology, resigned effective
September 30, 1997. Mr. Kent D.S. Durr, formerly Chairman and a director of the
Company, resigned effective December 31, 1997. There are no family
relationships between any of the directors or executive officers except as
stated above.

During the year ended December 31, 1997 there were six meetings of the
Board of Directors of the Company. Each director of the Company attended at
least 75% of such meetings during the period of his directorship.

The Board appointed an audit committee effective February 23, 1998
comprised of Messrs. Ralph E. Bailey and de Havilland. There are no other
committees of the Board of Directors. Compensation matters are determined by
the full membership of the Board.

Under the Certificate of Incorporation of the Company indemnification is
afforded the Company's directors and executive officers to the fullest extent
permitted by the provisions of the General Corporation Law of the State of
Delaware. Such indemnification also includes payment of any costs which an
indemnitee incurs because of claims against the indemnitee. The Company is,
however, not obligated to provide indemnity and costs where it is adjudicated
that the indemnitee did not act in good faith in the reasonable belief that the
indemnitee's actions were in the best interests of the Company, or, in the case
of a settlement of a claim, such determination is made by the Board of
Directors of the Company.

The Company carries insurance providing indemnification, under certain
circumstances, to all of its directors and officers for claims against them by
reason of, among other things, any act or failure to act in their capacities as
directors or officers. The annual premium for this policy is $69,500. No sums
have been paid for such indemnification to any past or present director or
officer by the Company or under any insurance policy.

RATIFICATION OF APPOINTMENT OF AUDITORS

The Board of Directors has appointed the firm of Ernst & Young LLP,
Certified Public Accountants ("Ernst & Young"), to be the Company's auditors
for the year 1998 and submits that appointment to stockholders for approval.
Ernst & Young served in that capacity for the years 1996 and 1997 and is
knowledgeable about the Company's operations and accounting practices and is
well-qualified to act in the capacity of independent accountants. A
representative of Ernst & Young will be present at the Meeting and will have an
opportunity to make a statement and be available to respond to appropriate
questions.

The appointment of auditors is approved annually by the Board and
subsequently submitted to the stockholders for ratification. In making the
appointment, the Board reviews Ernst & Young's performance in prior years along
with its reputation for integrity and overall competence in accounting and
auditing. The scope, timing, and fees applicable to the audit of the Company's
consolidated financial statements, as well as non-audit services, are also
reviewed and approved annually by the Board.

If the proposal is not approved, it is contemplated that the appointment
for 1998 will be permitted to stand, unless the Board finds other compelling
reasons for making a change. In view of the difficulty and expense involved in
changing independent accountants on short notice, disapproval of the proposal
will be considered as advice to the Board to select other independent
accountants for the following year.

The affirmative vote of a majority of the shares voting is required for
the approval of this proposal. The Company recommends a vote FOR this proposal.

INCREASE IN COMPANY SHARE CAPITAL

The Company's authorized share capital as presently set out in its
Certificate of Incorporation is five million shares of common stock and 100,000
shares of preferred stock, each of $0.05 par value. There are now issued and
outstanding 2,516,666 common shares and there are reserved for issuance 515,417
common shares on exercise of warrants or employee stock options.(See Note 5 to
the Financial Statements.) Additionally, the Company has reserved 833,333
common shares for conversion of 2,500 shares of the Company's Series A
convertible preferred stock (the "Series A Stock"). The Series A Stock which is
not now outstanding has been reserved for conversion of a Bridge Loan Facility
(the "Bridge Loan")in the amount of $1.25 million furnished to the Company as
of May 8, 1998. (See the more detailed description below under the captions
"Certain Relationships and Related Transactions -- Loans"). Accordingly, the
Company has now available for issuance only 1,134,584 common shares for all
purposes.

The Company estimates that the Bridge Loan Facility together with the
Company's other resources will satisfy the Company's cash requirements until
November 1998. The Company is seeking additional funds of from $3 to $5 million
for its general corporate purposes thereafter. The Company believes it will
require additional authorized common shares for any of the various types of
financing which might be offered to it, whether for sales of common shares,
conversion of other securities into common shares or for associated warrants.
An additional 10 million shares is believed reasonable under the circumstances
for such purposes. At the date of this proxy statement no such financing is
proposed. While the Company believes that such additional financing will be
obtained, there is no assurance that such financing will be obtained or, if
obtained, it will be offered on favorable terms.

The Company, therefore, believes that an increase of authorized capital
from 5 million to 15 million common shares, par value $0.05, is in order and a
resolution will be presented at the Meeting to amend the Certificate of
Incorporation of the Company to that effect. No increase in the authorized
amount of preferred stock is proposed.

The affirmative vote of a majority of the shares voting is required for
the approval of this proposal. The Company recommends a vote FOR this proposal.

EXECUTIVE COMPENSATION

The table below sets forth information concerning compensation for
services in all capacities awarded to, earned by or paid to Mr. Jeremy D.
Peter-Hoblyn, President and Chief Executive Officer, Mr. James M. Valentine,

Directors' Compensation

The Company provides an annual retainer of $15,000 and a meeting fee of
$2,000 per Board meeting and $1,000 per diem for services not involving board
meetings plus associated expenses for directors who are not employees of the
Company, except Mr. Ralph E. Bailey who is paid an annual retainer of $15,000
and is reimbursed for his expenses of attending meetings and for office
expenses as Chairman of the Company. Mr. Ralph E. Bailey, commencing October
1997, has deferred his annual retainer and expense payments pending improvement
in the Company's financial position. Where a non-employee director is employed
or otherwise compensated by an affiliated Company, such as Fuel-Tech N.V., the
retainer and meeting fees are paid to the affiliated company, unless waived.
Fuel Tech was paid those retainers and fees for 1997 in the amount of $56,850.
Directors who are employees of the Company receive no compensation for their
service as directors.

Compensation Committee Interlocks and Insider Participation

The Board of Directors of the Company did not have a Compensation
Committee during 1997. Accordingly, during 1997 each of the directors and
executive officers of the Company participated in deliberations and decisions
concerning his compensation.

REPORT OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION

Compensation Policies

Compensation for executives is based on the philosophy that compensation
must (a) be competitive with other businesses to attract, motivate and retain
the talent needed to lead and grow the Company's business, (b) be linked to the
Company's position as a development stage company requiring strong
entrepreneurial skills to achieve its long and short term goals, and (c)
encourage executive officers to build their holdings of the Company's stock to
align their goals with those of the stockholders.

Compensation of Executive Officers -- 1997

The key components of the Company's executive compensation program during
the last fiscal year were base salary and non qualified stock option awards
under the 1994 Plan. The cash based portion of compensation is fixed by the
Board in its discretion based upon historical levels, performance, ranking
within the officer group, amounts being paid by comparable companies, and the
Company's financial position. Stock options are designed to provide additional
incentives to executive officers to maximize stockholder value. Through the use
of vesting periods the option program encourages executives to remain in the
employ of the Company. In addition, because the exercise prices of such options
are set at the fair market value of the stock on the date of grant of the
option, executives can only benefit from such options, if the trading price of
the Company's shares increases, thus aligning their financial interests with
those of the stockholders. Finally, stock options minimize the Company's cash
compensation requirements.

Compensation of Chief Executive Officer -- 1997

The compensation of the Chief Executive Officer, Mr. Peter-Hoblyn, is made
up of base salary, stock options and a company-paid annuity. (See the Summary
Compensation Table above.) Mr. Peter-Hoblyn's base salary was not increased in
1997. The portion of that base salary allocable to the Company, however,
increased in 1997 from $229,667 to $250,000 solely because 100% of that base
salary became allocable to the Company in mid-year 1996 and thereafter no
portion was allocable to Fuel Tech. This amount of base salary was fixed in
1996 in the overall business judgement of the Board as to the proper
competitive level of salary paid by comparable companies. Also, Mr.
Peter-Hoblyn was awarded 35,000 non-qualified stock options under the Plan in
1997 in accordance with the Company's philosophy of providing incentives to
management aligned with the interests of the stockholders.

Effective February 16, 1998 Mr. Peter-Hoblyn voluntarily reduced his base
salary to $187,500 pending improvement in the Company's financial position.

Directors of the Company:

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Management and Services Agreement

Effective July 1995 and amended June 1996, the Company and Fuel Tech have
entered into a Management and Services Agreement (the "Services Agreement")
under which Fuel Tech's corporate staff provides certain administrative
services, including legal advice and services, risk management, tax advice and
certain technical and other services to the Company. The Company is assessed
fees equal to, depending on the type of service, 3% or 10% of the Company's
fixed reimbursable costs for these services. The fee may be changed by mutual
agreement of the Company and Fuel Tech. Management believes that the charges
under the Services Agreement are reasonable and that the terms of the Services
Agreement are fair to the Company. The Services Agreement may be canceled by
either party on or before May 15 in any year.

Technology Assignments

The Company's technology is comprised of patents, patent applications,
trade or service marks, data and know-how. A substantial portion of this
technology is held under assignments of technology from Fuel Tech and Fuel Tech
affiliates. The assignments provide for running royalties payable to Fuel Tech
commencing in 1998 of 2.5% of gross revenues derived from platinum fuel
catalysts. The Company may at any time terminate the royalty obligation by
payment to Fuel Tech in any year from 1998 through 2008 of amounts, depending
on the year, declining from $12 million to $1.1 million.

Term Loan

Under an unsecured promissory note of November 5, 1997, the Company
borrowed $494,620 from Fuel Tech repayable at 8% interest in installments of
$100,000 on July 1 in each of 1998 through 2000 and $194,620 on July 1, 2001.

Short Term Loan

Also, by a note and security agreement the Company obtained a short-term
loan facility of up to $500,000 at 10% interest due June 17, 1998. Borrowings
under this instrument are secured by a security interest on all of the
Company's intellectual property.

Bridge Loan

Fuel Tech and a group of London based investors (the "Bridge Loan
Lenders") have executed a letter of intent with the Company to provide the
Company with a Bridge Loan Facility (the "Bridge Loan") of $1.25 million at 10%
interest due April 15, 2001, secured by all of the intellectual property of the
Company. The $500,000 Fuel Tech note and security agreement referred to above
will be canceled and Fuel Tech's $500,000 portion of the Bridge Loan will
substitute for that instrument. The Bridge Loan will, as a debt instrument and
through its security interest, be preferred in liquidation over all other
securities of the Company, debt or equity. No class of debt senior to the
Bridge Loan may be issued absent the prior consent of a majority in interest of
the Bridge Loan Lenders.

The Bridge Loan Facility may be converted into up to 2,500 shares of
Series A Convertible Preferred Stock (the "Series A Stock") of the Company at
any time at the option of the several Bridge Loan Lenders but is required to be
converted on (1) the conclusion of a public or private financing contributing
at least $1.75 million of net proceeds to the Company, or (2) voluntary
conversion of at least 60% of the Bridge Loan.

John A. de Havilland, a director of the Company and of Fuel-Tech N.V., is
also a director of The Shimpling Trust Limited which is a Bridge Loan Lender in
the amount of $250,000.

Terms of Series A Convertible Preferred Stock

On March 31, 1998 the Board of Directors pursuant to its authority under
the Certificate of Incorporation of the Company authorized 10,000 shares of
Series A Stock which is valued at $500 per share, will pay accruable dividends
of 9% (11% if paid in kind at the Company's option) and will be convertible at
the conversion price of $1.50 per share (a rate of 333.33 common shares for
each share of Series A Stock). This conversion ratio will have a weighted
average price adjustment for anti-dilution protection which shall be waived as
to shares of Series A Stock if the Holder thereof does not purchase at least
its pro-rata portion, on a fully diluted basis, of a Company offer of another
series of preferred stock. Mandatory conversion will occur of all Series A
Stock and accrued and unpaid dividends thereon in the event of an underwritten
public offering providing the Company with at least $10 million in gross
proceeds at a price per share of at least 20% of the conversion price. The
Series A Stock may be converted at the option of the Company, if Company common
shares trade at a minimum price of $4.50 per day for 20 consecutive trading
days, which conversion may be delayed at the option of 60% of the holders of
Series A Stock pro rata quarterly over the following 18 months. The Series A
Stock will be senior to all other classes of Company stock and will have a
liquidation preference equal to its issue price per share. Holders of Series A
Stock shall have the pro rata right based on their fully diluted percentage of
equity ownership to purchase shares of subsequent equity issues of the Company
and such shares not purchased by such Holders shall be reallocated for purchase
among the other Holders of Series A Stock. The Company may redeem Series A
Stock in four equal quarterly installments at any time after four years from
issue. Holders of Series A Stock may vote pari passu with the common on an as
converted basis and will vote as a class for the election of two directors. In
addition, the following actions by the Company will require approval of holders
of 60% of the Series A Stock, voting as a class: (1) the creation of security
senior to or ranking pari passu with the Series A Stock, (2) payment of
dividends on common shares, (3) repurchase of common shares except on
termination of employment, (4) a transaction involving change in control of the
Company (5) an increase in the number of authorized Series A Stock, (6) any
change materially adverse to the rights, preferences and privileges of the
Series A Stock, and (7) any change in the size of the Board of Directors of the
Company.

Registration Rights

The Company has agreed as of November 15, 1997 under certain circumstances
to provide registration rights to Fuel-Tech N.V. for one demand and unlimited
incidental registrations at Company cost for the sale of Company common shares
held by Fuel-Tech N.V., if such registration should be legally required for
Fuel Tech to sell such shares.

The terms of the Bridge Loan Facility provide that on conversion of the
Notes to Series A Stock, the holders of Series A Stock may have three demand
(each of at least $1 million in value and not more often than one in any twelve
months) and unlimited incidental registrations at Company cost for the common
shares underlying the Series A Stock held by the Holders, if registration
should be legally required for such Holders to sell such underlying common
shares.

Relationship with Fuel Tech; Conflicts of Interest

Directors and officers of Fuel Tech and its subsidiaries who are also
directors and officers of the Company, and Fuel Tech as the Company's
controlling stockholder, are in positions involving the possibility of
conflicts of interest with respect to transactions involving the Company.

The Company and Fuel Tech have entered into contractual arrangements
governing certain transactions and relationships between them. These agreements
were executed while the Company was a subsidiary or affiliate of Fuel Tech and
were not the result of arm's-length negotiations. Accordingly, there is no
assurance that the terms and conditions of these agreements are as favorable to
the Company as might have been obtained from independent third parties.

Seven of the Company's officers or directors are employees, directors or
nominees to the Board of Fuel Tech. Three of these persons are also officers of
Fuel Tech and Fuel Tech subsidiaries. Although these persons seek to devote
such time to the affairs of the Company as the Company's needs require, they
must balance the Company's need for their time with the needs of Fuel Tech and
its subsidiaries.

Ralph E. Bailey and Douglas G. Bailey, nominees for election as directors
of the Company have been elected Managing Directors of Fuel-Tech N.V. which
owns 27.4 percent of the issued and outstanding common shares of the Company.
Pursuant to a Securities Purchase Agreement dated as of March 23, 1998 (the
Purchase Agreement) certain affiliates and related parties of ABC (the
"Investors") have purchased 4.75 million common shares of Fuel Tech and
warrants to purchase an additional 3 million of such common shares. Under the
terms of a related Shareholders Agreement the Investors, for a period of ten
years and so long as they own not less than a certain specified minimum
percentage of the issued and outstanding common shares of Fuel Tech, will be
entitled from time to time to nominate two Managing Directors of Fuel-Tech N.V.
who are representatives of the Investors and one independent director. Also,
during such period the Investors will be entitled to nominate up to 50% of the
directors of Fuel Tech, Inc., the operating subsidiary of Fuel Tech which owns
substantially all of the operating assets of the Fuel Tech Group. The
transactions contemplated by the foregoing are subject to certain conditions,
including approval by the shareholders of Fuel-Tech N.V. common stock.

The Company expects to resolve potential conflicts of interest with Fuel
Tech on a case-by-case basis, taking into consideration relevant factors
including its existing agreements with Fuel Tech, applicable stock exchange
rules and prevailing corporate practices. Fuel Tech, however, may exercise its
influence in its own best interests.
