1.       Purpose and Effective Date

         The purpose of this 1993 Incentive Plan of Fuel-Tech N.V., a
Netherlands Antilles corporation ("the Corporation") is to further the interests
of the Corporation and its shareholders by providing incentives in the form of
awards to such directors, officers, employees, consultants or advisors to the
Corporation or any of its Subsidiaries as the directors shall determine are key
to the continued success and profitability of the Corporation. The Plan is
intended to retain Participants with significant training, experience and
ability; to attract new Participants whose services are considered valuable; and
to encourage such Participants to acquire a proprietary interest in the
Corporation. So that the maximum incentive can be provided each Participant in
the Plan by granting to such participant an Award best suited to the
circumstances, the Plan provides for granting, Non-Qualified Stock Options,
Incentive Stock Options, Stock Appreciation Rights, Restricted Shares,
Performance Awards, Bonuses, Other Awards, or any combination of the foregoing.

Board, subject to approval within one (1) year of such adoption by the

         5.2      Share Accounting

         Shares related to Awards that are forfeited, terminate, expire
unexercised, exchanged, settled in cash in lieu of Shares or settled in such
other manner so that a portion or all of the Shares included in an Award are not
issued to a Participant shall be available for other Awards. Any Shares not so
used shall be available for further Awards. Shares issued under this Plan shall
be authorized and unissued Shares or Shares reacquired by the Corporation, as
determined by the Committee. No fractional Shares shall be issued under this
Plan.

6.       Awards

         Awards may include, but are not limited to, those described in this
Section 6. Awards may be granted singly, in combination, or in tandem with other
Awards. Subject to the other provisions of this Plan, Awards may also be made in
combination or in tandem with, in replacement of, or as alternatives to, grants
or rights under this Plan and any other plan of the Corporation, including any
plan of any acquired entity and for the benefit of any present or former
director, officer, consultant or agent of such acquired entity. Subject to the
terms of the Awards described in this Section 6 and the related Award Agreement,
the form of payment for Awards may be in cash, in Shares, in Share Units, or
such other form as determined by the Board or the Committee, and may be made
partly in one form and partly in one or more other forms, all as determined by
the Committee. Except as otherwise provided in this Plan, Awards shall be
evidenced by Award Agreements, the terms of which other than a Director Option
may be amended or accelerated by the Board or Committee following the grant of
any Award and need not be uniform among Participants. Except as otherwise
provided in this Plan, Awards shall be granted for such minimum consideration as
is required by applicable law, rules and regulations, including without
limitation, the then applicable Rule 16b-3, and such additional consideration,
if any, as may be determined by the Committee.

         6.1      Options

         Non-Qualified and Incentive Stock Options may be granted under this
Plan from time to time. Director Options shall be granted under this Plan only
at such times as provided below. Subject to Sections 6.1(h) and 6.1(i), Options
shall be granted upon the following terms and conditions with such additional
terms and conditions, not inconsistent with the provisions of this Plan, as the
Board or Committee in its discretion shall deem desirable:

                  (a) No Option shall be exercisable after the expiration of ten
         (10) years from the date it is granted (five (5) years in the case of
         an Incentive Stock Option granted to a Ten-Percent Stockholder);
         provided, however, that if a Director or Participant dies, his or her
         non-qualified stock option shall remain exercisable for one (1)
         additional year beyond the ten year term, if such term shall expire
         within one (1) year of death.

                  (b) The option price per Share for all Options shall be not
         less than one hundred per cent (100%) of the Fair Market Value Per
         Share on the date the Option is granted (one hundred ten percent (110%)
         in the case of an Incentive Stock Option granted to a Ten-Percent
         Stockholder).

                  (c) Award Agreements for Options shall conform to the
         requirements of this Plan, and other than with respect to Director
         Options may contain such other provisions as the Committee shall deem
         advisable.

                  (d) Award Agreements for Options shall specify when an Option
         may be exercisable. An Option may be exercised, in whole or in part, by
         giving written notice of exercise to the Corporation specifying the
         number of Shares to be purchased. Shares purchased upon exercise of an
         Option shall be paid for in full at the time the Option is exercised in
         cash or in Shares. Payment may also be made in any other manner or form
         approved by the Board or Committee, consistent with applicable law,
         regulations and rules.

                  (e) A holder of an Option shall have no rights as a
         stockholder with respect to any Shares covered by such Option unless
         and until the date of the issuance of the stock certificate for such
         Shares.

                                       7
<PAGE>

                  (f) (i) If, after completion of any required period of
         continuous employment in order to exercise an Option as provided in an
         Award Agreement, a Participant dies while employed by the Corporation
         or its Subsidiaries, such Option shall be exercisable by the
         Beneficiary thereof, but after the date of death of the Participant
         only within the period specified in the Award Agreement which shall not
         be later than the expiration date of the Option as extended under
         ss.6.1(a), above.

                           (ii) Following the death of a Participant, the Board
         or Committee may at its discretion, upon the request of such
         Participant's Beneficiary who holds an exercisable Option and in
         consideration of the surrender of such Option, pay the amount by which
         the Fair Market Value Per Share on the date of such request shall
         exceed the Option price per Share multiplied by the number of Shares as
         to which the request was made.

                  (g) If, after completion of any required period of continuous
         employment in order to exercise an Option as provided in an Award
         Agreement, a Participant is Totally Disabled or Retires, such Option
         shall be exercisable by the Participant, but only within the period
         specified in the Award Agreement.

                  (h) Incentive Stock Options.

                           (i) Each Incentive Stock Option shall not have an
         aggregate Fair Market Value Per Share (determined for each Incentive
         Stock Option at its grant date) of Shares with respect to which
         Incentive Stock Options are exercisable for the first time by a
         Participant during any calendar year (under the Plan and any other
         employee stock option plan of the Corporation or any of its
         Subsidiaries ("Other Plans")), determined in accordance with the
         provisions of Section 422 of the Code, which exceeds $100,000;

                           (ii) To the extent that the aggregate Fair Market
         Value Per Share of stock with respect to which Incentive Stock Options
         granted under the Plan and any Other Plans are exercisable by a
         Participant for the first time during any calendar year exceeds
         $100,000, such Incentive Stock Options shall be treated as
         Non-Qualified Stock Options to the extent necessary so that such
         aggregate Fair Market Value Per Share of stock does not exceed
         $100,000. For purposes of the foregoing sentence, Incentive Stock
         Options shall be treated as Non-Qualified Stock Options according to
         the order in which they were granted such that the most recently
         granted Incentive Stock Options are first treated as Non-Qualified
         Stock Options.

<PAGE>

                           (iii) Each Incentive Stock Option shall require the
         Participant to notify the Board or Committee of any disposition of any
         Shares issued pursuant to the exercise of the Incentive Stock Option
         under the circumstances described in Section 421(b) of the Code
         (relating to certain disqualifying dispositions), within ten (10) days
         of such disposition.

         each Director Option granted under the Plan:

         Corporation and who is not an employee of the Corporation or any of its
         Subsidiaries shall be granted a Director Option in respect of 10,000
         Shares on the first business day after the annual meeting of the
         stockholders of the Corporation in each year that the Plan is in
         effect, provided that the individual is a director of the Corporation
         on such date.

                           (b) Each Director Option shall become fully vested
         and exercisable upon grant with respect to one-hundred percent (100%)
         of the Shares subject thereto.

                           (c) Each Director Option shall terminate on such date
         or under such circumstances as may be provided in the respective Award
         Agreement, but no later than the date which is the tenth anniversary of

         part or all of, in addition to, or completely independent of, an Option
         or any other Award under this Plan. A Stock Appreciation Right issued
         in tandem with an Option may be granted at the time of grant of the
         related Option or at any time thereafter during the term of the Option.

         holder thereof shall be entitled to receive a number of Shares equal in
         aggregate value to the amount by which the Fair Market Value Per Share
         on the date of such exercise shall exceed the Option price per Share of
         the related Option, multiplied by the number of Shares in respect of
         which the Stock Appreciation Rights shall have been exercised.

                           (iii) All or any part of the obligation arising out
         of an exercise of Stock Appreciation Rights may, at the discretion of
         the Board or Committee, be settled by the payment of cash equal to the
         aggregate value of the Shares (or a fraction of a Share) that would

         unexercised tandem Options of the Participant shall automatically

discretion shall deem desirable:

                  (a) Restricted Shares are Shares which are subject to such
         terms, conditions and restrictions as the Board or Committee deems
         appropriate, which may include restrictions upon the sale, assignment,
         transfer or other disposition of the Restricted Shares and the
         requirement of forfeiture of the Restricted Shares upon termination of
         employment under certain specified conditions. The Board or Committee
         may condition the lapsing of restrictions on part or all of an Award of
         Restricted Shares upon the attainment of specific performance goals or
         such other factors as the Board or Committee may determine. Awards of
         Restricted Shares may be granted for no cash consideration or for such
         minimum consideration as may be required by applicable law.

                  (b) Award Agreements for Restricted Shares shall conform to
         the requirements of this Plan, and may contain such other terms and
         conditions (including but not limited to, a description of a period
         during which the Participant may not transfer the Restricted Shares and
         limits on encumbering the Restricted Shares during such period) as the
         Board or Committee shall deem desirable. To the extent permitted by
         Section 13.3 hereof, the Board or Committee may provide for the lapse
         of any such term or condition in installments and may accelerate or
         waive any such term or condition in whole or in part, based on service,
         performance and/or such other factors or criteria as the Board or
         Committee may determine.

                  (c) Award Agreements for Restricted Shares shall provide that
         the stock certificates representing Restricted Shares shall be
         legended, that the stock certificates shall be held by a custodian, or
         that there be other mechanisms for maintaining control by the
         Corporation of the Restricted Shares until the restrictions thereon are
         no longer in effect. After the lapse, waiver or release of the
         restrictions imposed pursuant to the Award Agreement on any Restricted
         Shares, the Corporation shall cause to be issued in the Participant's
         name a stock certificate evidencing the Restricted Shares with respect
         to which the restrictions have lapsed or been waived or released, free
         of any legend, and shall cause such stock certificate to be delivered
         to the Participant.

                  (d) Except as otherwise provided in this Plan or in the Award
         Agreement, the Participant shall have, with respect to Awards of
         Restricted Shares, all of the rights of a shareholder of the
         Corporation, including the right to vote the Restricted Shares and the
         right to receive any cash or stock dividends on such Restricted Shares.
         The Board or Committee may provide that the payment of cash dividends
         shall or may be deferred. Any reinvestment of deferred cash dividends
         shall be as determined by the Board or Committee. Stock dividends
         issued with respect to Restricted Shares shall be Restricted Shares and
         shall be subject to the same terms, conditions and restrictions that
         apply to the Restricted Shares with respect to which such dividends are
         issued. Any additional Shares issued with respect to cash or stock
         dividends shall not be counted against the maximum number of Shares for
         which Awards may be granted under this Plan as set forth in Section 5.

                  (e) If the employment of a Participant is terminated prior to
         the lapse of restrictions on Restricted Shares because the Participant
         dies or becomes Totally Disabled, the restrictions on all Restricted
         Shares awarded to a Participant shall lapse on the date of such
         termination.

         6.4      Performance Awards

         Performance Awards may be granted under this Plan from time to time. If
Performance Awards are granted they shall be upon the following terms and
conditions and such additional terms and conditions, not inconsistent with the
express provisions of this Plan, as the Board or Committee in its discretion
shall deem advisable:

                  (a) Performance Awards are Awards which are based upon the
         long-term performance of all or a portion of the Corporation or which
         are based upon the long-term individual performance of a Participant.
         Performance Awards may be in the form of performance units, performance
         shares and such other forms of Performance Awards which the Board or
         Committee shall determine to be desirable. Performance Awards are
         Awards which are granted to participants contingent upon (i) the future
         performance of all or a portion of the Corporation which may include,
         without limitation, performance relative to a group of companies in the
         same or related industries, achievement of specific business
         objectives, growth rates or profitability or earnings goals (in respect
         of, for example, Share price, return on equity or return on assets) and
         such other measurements as the Board or Committee determines to be
         appropriate, (ii) the future performance of a Participant, which may
         include, without limitation, attainment of specified goals and
         objectives and such other measurements as the Board or Committee
         determines to be appropriate, (iii) the future performance of a
         combination of all or a portion of the Corporation and a Participant,
         or (iv) such other measurements and criteria as may be considered
         appropriate by the Board or Committee. Performance Awards may contain
         multiple performance measurements.

                                       12
<PAGE>

                  (b) Award Agreements for Performance Awards shall conform to
         the requirements of this Plan and may contain such other terms and
         conditions as the Board or Committee shall deem desirable, including
         but not limited to, applicable performance measurements, a description
         of whether performance measurements are to be used singly or in
         combination, a description of whether different performance
         measurements may be used for different performance periods, the length
         of performance periods, the ability of the Board or Committee to amend
         and adjust measurements, payouts and performance periods of performance
         Awards and any requirements of employment during performance periods.

                  (c) Award Agreements for Performance Awards shall provide for
         a required minimum period of continuous employment during a performance
         period of a Performance Award. If such minimum period of continuous
         employment shall have elapsed, the Award Agreement may provide, or the
         Board or Committee may determine, the portion of the payment of the
         Performance Award which Participant or the Participant's beneficiary,
         as applicable, is to receive at the end of the performance period.

         6.5      Bonuses

                  Bonuses may be granted under this Plan from time to time on an
annual or one-time basis. The amount of Bonuses which may be awarded shall be as
determined by the Board or Committee. The Board or Committee may establish a
basis upon which aggregate Bonus expenditures for any year shall be determined,
which may include measurements of financial performance of the Corporation or of
a unit or department thereof, relative performance of the Corporation or of a
department thereof within the same or related industries, competitive
compensation considerations and other measurements and criteria.

                                       13
<PAGE>

                  (a) Each Bonus may be made at the discretion of the Board or
         Committee either in cash, in Shares, in Share Units, or in another form
         as determined by the Board or Committee and may be made partly in one
         form and partly in one or more other forms. In the case of an Award of
         a Bonus in Shares or Share Units, the number shall be determined by
         using the Fair Market Value Per Share on the date of the Award of the
         Bonus.

                  (b) The payment of any Bonus shall be subject to such
         obligations or conditions as the Board or Committee may specify in
         making or recommending the Award of the Bonus, but Bonuses need not be
         evidenced by Award Agreements.

                  (c) When payment of all or part of a Bonus is deferred in the
         form of Shares or Share Units, the account of the Participant to whom
         the Bonus was made will be credited with an amount per Share equal to
         the dividends payable on each issued and outstanding Share ("dividend
         equivalents"). Amounts thus credited shall, in the discretion of the
         Board or Committee, either:

                           (i) be paid in cash as and when each such credit
shall be made, or

                           (ii) be credited in Shares or Share Units, with the
         number determined by using the Fair Market Value Per Share on the date
         of the dividend payment and delivered in such form and at such time or
         times as may be determined by the Committee.

                  (d) When payment of all or part of a Bonus is deferred in
         cash, the Committee may provide that the account of the Participant to
         whom the Bonus was made shall be credited with amounts equivalent to
         interest ("interest equivalents"). Amounts thus credited shall be at
         the rate determined by the Committee.

                  (e) Any Bonus payable in Shares may, in the discretion of the
         Board or Committee, be paid in cash, on each date on which payment in
         Shares would otherwise have been made, in an amount equal to the Fair
         Market Value Per Share on each such date, multiplied by the number of
         Shares which would otherwise have been paid on such date.

                  (f) Bonuses may be awarded in Share Units in accordance with
         the following terms and conditions and such other terms and conditions
         as the Board or Committee may impose:

                                       14
<PAGE>

                           (i) The number of Share Units awarded with respect to
         any Bonus shall be the number determined by using the Fair Market Value
         Per Share on the date of the Award of the Bonus.

                           (ii) Any Bonus made in Share Units may, in the
         discretion or on the recommendation of the Board or Committee, be paid
         in Shares on each date on which payment in cash would otherwise be
         made.

                  (g) In lieu of the foregoing forms of payment of Bonuses, the
         Board or Committee may specify or recommend any other form of payment
         which it determines to be of substantially equivalent economic value to
         the cash value of the Bonus including, without limitation, forms
         involving payments to a trust or trusts for the benefit of one or more
         Participants.

                  (h) Each payment of a Bonus that is to be made in cash shall
         be from the general funds of the Corporation or its respective
         subsidiary or affiliate, as the case may be.

                  (i) In the event of the death of a Participant to whom a Bonus
         is to be or shall have been made, the Bonus or any portion thereof
         remaining unpaid shall be paid to such Participant's Beneficiary under
         the Participant's will or pursuant to the relevant laws of descent and
         distribution.

         6.6      Other Awards

                  (a) The Board or Committee may grant other Share based Awards
         under this Plan, including without limitation, those Awards pursuant to
         which Shares are or may in the future be acquired, Awards denominated
         in Share Units, securities convertible into Shares and dividend
         equivalents. The Board or Committee shall determine the terms and
         conditions of such other Share based Awards. Shares issued in
         connection with such other Share based Awards shall be issued for such
         minimum consideration as shall be required by applicable law, rules and
         regulations, including the then applicable Rule 16b-3, and such
         additional consideration, if any, as may be determined by the Board or
         Committee.

                  (b) The Board or Committee may also grant other non-Share
         based Awards under this Plan and shall determine the terms and
         conditions of such other non-Share based Awards in tandem or
         combination with other Awards or each other, in exchange of other
         Awards, or in tandem or combination with, or as alternatives to grants
         or rights under any other employee plan of the Corporation, including
         any plan of any acquired entity. The Board or Committee shall have the
         authority to determine the Participants for such Awards and all other
         terms and conditions of such other Awards. No amendment of this Plan is
         required for the creation of another type of Award.

                                       15

7.       Adjustments Upon Changes in Capitalization

                  (a) Subject to any required action by the Corporation's
         stockholders, in the event of a reorganization, recapitalization, stock
         split, stock dividend, exchange of Shares, combination of Shares,
         merger, consolidation or any other change in corporate structure of the
         Corporation affecting the Shares, or in the event of a sale by the
         Corporation of all or a significant part of its assets, or any
         distribution to its shareholders other than a normal cash dividend, the
         Board or Committee may make appropriate adjustment in the number, kind,
         price and value of Shares authorized by this Plan and any adjustments
         to outstanding Awards as it determines appropriate so as to prevent
         dilution or enlargement of rights.

                  (b) The existence of an Award under this Plan shall not affect
         in any way the right or power of the Corporation or its shareholders to
         make or authorize any or all adjustments, recapitalizations,
         reorganizations or other changes in the Corporation's capital structure
         or its business, or any merger or consolidation of the Corporation, or
         any issue of bonds, debentures, preferred or prior preference stocks,
         or loan notes ahead of or affecting the Stock or rights thereunder or
         convertible thereto, or the dissolution or liquidation of the
         Corporation, or any sale or transfer of all or any part of its assets
         or business or any other corporate act or proceeding, whether of a
         similar character or otherwise.

8.       Change in Control

         8.1      Definition of Change in Control

         A "Change in Control" shall be deemed to have occurred if any one or
more of the events described in paragraphs (a), (b) or (c) below occurs.

                  (a) Any "person," as such term is used in Sections 13(d) and
         14(d) of the Exchange Act (including any group of persons with which
         any person or its affiliates or associates, as such terms are defined
         in Rule 12b-2 under the Exchange Act has any agreement, arrangement or
         understanding, oral or written, regarding the acquiring, holding,
         voting or disposing of any of the Corporation's securities, but
         excluding a trustee or other fiduciary holding securities under an
         employee benefit plan of the Corporation) (i) becomes the "beneficial
         owner" (as defined in Rule 13d-3 under the Exchange Act), directly or
         indirectly, of securities of the Corporation representing fifty one
         percent (51%) or more of the combined voting power of the Corporation's
         then outstanding securities (hereinafter referred to as an "Acquiring
         Person"); or

                                       16
<PAGE>

                  (b) In any two (2) year period persons being a majority of the
         Board shall cease to be so unless the nomination of the new directors
         during such period was approved by at least a majority of the directors
         then still in office who were directors at the beginning of the period;
         or

                  (c) A consolidation or merger or "Business Combination," as
         that term is defined as of the effective date of this Plan in Section
         203(c)(3) of The General Corporation Law of Delaware, of the
         Corporation shall occur (with the term "interested shareholder" as used
         in that Section being deemed to refer to an Acquiring Person) in which
         the Corporation is not the surviving Corporation and pursuant to which
         the Corporation's Shares are converted to cash, securities or other
         property but not a consolidation or merger or Business Combination
         where shareholders of the Corporation prior to the Business Combination
         have substantially the same proportionate ownership in a business
         entity after the consolidation or merger or Business Combination; or

                  (d) The shareholders of the Corporation shall approve any plan
         for liquidation or dissolution of the Corporation not otherwise
         involving a transaction where shareholders of the Corporation prior to
         the transaction have substantially the same proportionate ownership of
         a business entity after the transaction.

                  (e) In no event, however, shall a Change in Control be deemed
         to have occurred with respect to a Participant, if that Participant is
         part of an Acquiring Person which consummates the Change in Control
         transaction. A Participant shall be deemed "part of an Acquiring
         Person" for purposes of the preceding sentence if the Participant is an
         equity participant or has agreed to become an equity participant in the
         Acquiring Person (except for (i) passive ownership of less than three
         percent (3%) of the securities of the Acquiring Person; or (ii)
         ownership of equity participation in the Acquiring Person which is
         otherwise not deemed to be significant, as determined prior to the
         Change in Control by a majority of the disinterested "Continuing
         Directors"). For purposes of this Section 8.1, "Continuing Directors"
         means those directors (x) who were directors of the Board immediately
         prior to the Change in Control transaction ("Incumbent Directors") and
         (y) whose election, or nomination for election by the Corporation's
         stockholders, was approved by a vote of at least a majority of the
         Incumbent Directors.

         8.2      Effect of Change in Control

         Upon the occurrence of an event of Change in Control, unless otherwise
with respect to any Award specifically prohibited by the terms of the second
paragraph of Section 6:

                  (a) Any and all Options and Stock Appreciation Rights shall
         become immediately exercisable.

                  (b) Any restriction periods and restrictions imposed on
         Restricted Shares (except such as may be required by relevant
         securities laws) shall lapse, and within ten (10) business days after
         the occurrence of a Change in Control, the stock certificates
         representing Restricted Shares, without any restrictions or legend
         thereon (except a legend as may be required by relevant securities
         laws), shall be delivered to the applicable Participants;

                  (c) The goal, objective, target value or the like, attainable
         under all Performance Awards shall be deemed to have been fully earned
         for the entire performance period as of the effective date of the
         Change in Control, except that all Performance Awards which shall have
         been outstanding less than six (6) months on the effective date of the
         Change in Control shall not be deemed to have earned the goal,
         objective, target value, or the like; and

                  (d) Subject to Section 14.3 hereof, all such other actions and
         modifications to the Awards as determined by the Board or Committee to
         be appropriate before the Change in Control of the Corporation shall
         become effective.

                                       18

9.       Relationship of the Plan to Benefit Plans

         The amount of Bonuses to any Participant under this Plan shall be
eligible for inclusion in the Participant's earnings base for the purpose of
determining the benefits to which the Participant is entitled under retirement,
pension, excess benefit, thrift, savings, profit-sharing, insurance, long-term
disability and other benefit plans, if any, of the Corporation or its
Subsidiaries as determined by the Board or Committee. No other income of a
Participant attributable to this Plan shall be included in the Participant's
earnings for purposes of any benefit plan in which the Participant may be
eligible to participate.

10.      Effect of the Plan On Right to Continued Employment and
         Interest in Particular Property

                  (a) None of the existence of this Plan, any Awards granted
         pursuant hereto or any Award Agreement shall create any right to
         continued employment of any Participant by the Corporation or its
         Subsidiaries. No Participant shall have, under any circumstances, any
         interest whatsoever, vested or contingent, in any particular property
         or asset of the Corporation or in any particular Share or Shares of the
         Corporation that may be held by the Corporation (other than Restricted
         Shares held by a custodian) by virtue of any Award. A Participant may
         be granted additional Awards under this Plan under such circumstances
         and at such times as the Board or Committee may determine; provided,
         however, that no participant shall be entitled to any Award in the
         absence of a specific grant by the Board or Committee of an Award,
         notwithstanding the prior grant of an Award to such Participant.

                  (b) This Plan shall not be deemed a substitute for, and shall
         not preclude the establishment or continuation of any other plan,
         practice or arrangement that may now or hereafter be provided for the
         payment of compensation, special awards or benefits to directors,
         officer, employees, consultant and agents of the Corporation and its
         Subsidiaries generally, or to any class or group of employees,
         including without limitation, any retirement, pension, excess benefit,
         thrift, savings, profit-sharing, insurance, long-term disability,
         health care plans or other employee benefit plans. Any such
         arrangements may be authorized by the Corporation and payment
         thereunder made independently of this Plan.

11.      Withholding Taxes and Deferrals

         11.1     Cash Withholding

         The Corporation and its participating subsidiaries shall have the right
to deduct from any cash payment made under Awards under this Plan any federal,
state, provincial or local income, or other taxes required by law to be withheld
with respect to such payment or to take such other action as may be necessary in
the opinion of the Corporation to satisfy all obligations for the payment of
such taxes.

         11.2     Share Withholding

         Any Share based Award may provide by the grant thereof that the
recipient of such Award may elect, in accordance with any applicable laws, rules
and regulations, to pay a portion or all of the amount of such minimum required
withholding taxes in Shares. In such event, the Participant shall authorize the
Corporation to withhold, or shall agree to deliver to the Corporation, Shares
owned by such Participant or a portion of the Shares that otherwise would be
distributed to such Participant, having a Fair Market Value equal to the amount
of withholding tax liability.

         11.3     Deferrals

         The Board or Committee may require or permit a Participant to defer
such Participant's receipt of the payment of cash or the delivery of Shares that
would otherwise be due to such Participant by virtue of the exercise, the
satisfaction of any requirements or goals or lapse or waiver of restrictions of
an Award made under this Plan. If any such deferment election is required or
permitted, the Board or Committee shall establish rules and procedures for such
payment deferrals.

12.      Compliance With Applicable Legal Requirements

         No certificate for Shares distributable pursuant to this Plan shall be
issued and delivered unless the issuance of such certificate complies with all
applicable legal requirements including, without limitation, compliance with the
provisions of applicable state securities laws, the Securities Act of 1933, as
amended from time to time or any successor statute, the Exchange Act and the
requirements of the exchanges on which Shares may, at the time, be listed, and
the provisions of any foreign securities laws or the rules of foreign securities
exchanges, where applicable.

13.      Amendments

         13.1     Plan Amendments

         The Board may, insofar as permitted by law, from time to time, with
respect to any Shares at the time not subject to Awards, suspend or discontinue
this Plan or revise or amend it in any respect whatsoever, provided, however,
unless the Committee or the Board, as appropriate, specifically otherwise
provides, any revision or amendment that would cause this Plan to fail to comply
with any requirement of applicable law, regulation or rule if such amendment
were not approved by the stockholders of the Corporation shall not be effective
unless and until the approval of the stockholders of the Corporation is
obtained.

         13.2     Award Amendments

         Subject to the terms and conditions and within the limitations of this
Plan, the Board or Committee may amend, cancel, modify, or extend outstanding
Awards granted under this Plan.

shall be the number exercised less a number equal in value to the exercise price
as of the date of exercise. Value for purposes of exercise by delivery of
previously owned Stock or by a Net Issue exercise request shall be determined in
the same manner as the determination of value under the Plan for the grant of
option Awards.

deliver to the Company, if required by the Company, a check payable to the
Company equal, in the sole opinion of the Company, to the applicable National,

non-exercisable immediately at 5:00 p.m. upon the date which is thirty (30) days
after such termination of the Participant's status;

(ii) death, total disability or normal retirement, such portion of this option
that has not then vested shall terminate immediately but such portion of this
Option that has then vested may be exercised by the Participant or, pursuant to
and as defined in the Plan, the Participant's Beneficiary at any time during the
period ending on the earlier of (x) the Expiration Date (provided that such
option would have been able to have been exercised according to its terms absent

(b) Notwithstanding the foregoing, where termination shall not have been for
cause, of which the Board shall be the sole judge, the Board may in its sole
discretion permit options hereunder to be exercised by the Participant at any
time during the period ending not later than the Expiration Date as the Board

according to its terms absent termination.

(c) "Normal Retirement" shall mean resignation of the Participant's status as an
employee of the Company or a subsidiary thereof on or after attaining age
sixty-five (65) or such earlier age as to which the Board shall consent. "Cause"

under, or a plea of guilty by the participant to any State or Federal felony
charge (or the equivalent thereof outside of the United States); any instance of

respect to the Company regardless of amount; substance or alcohol abuse; or
other conduct for which dismissal has been identified in the Fuel Tech, Inc.
Employee Handbook, or any successor manual, as a potential disciplinary measure.

         4. Method of Exercise. This Option may be exercised only by one or more

Participant's check or a bank check in the amount of the exercise price, or by
delivery to the Company by the Participant of shares of Stock previously owned
equal in value to the exercise price as of the date of exercise, or by a request
in the Participant's notice of exercise that the Participant desires a "Net
Issue" exercise of the Option. "Net Issue" means delivery to the Participant in
complete satisfaction of the exercise, that number of shares of Stock which
shall be the number exercised less a number equal in value to the exercise price
as of the date of exercise. "Value" for purposes of exercise by delivery of
previously owned shares or by a Net Issue exercise request shall be determined
in the same manner as the determination of value under the Plan for the grant of
option awards.

         5. Taxes. At the time of exercise of this Option, the Participant shall
deliver to the Company, if required by the Company, a check payable to the
Company equal, in the sole opinion of the Company, to the applicable national,
state, provincial and local income or other taxes and other pay-roll related
items legally required to be withheld by reason of such exercise.

         6. Securities Laws. The Stock may only be purchased if there is with
respect to the Stock a registration statement or qualification in effect under
applicable U.S. or State securities laws or an exemption therefrom.

         7. Transferability; Disqualifiying Dispositions. In order that this
Option shall continue as an Incentive Stock Option, this Option may not be
transferred otherwise than by will or the laws of descent and distribution and
may not be exercised by any person other than the Participant during the
Participant's lifetime. In order that shares acquired by exercise hereunder
shall not be the subject of a disqualifying disposition and ineligible for the
tax treatment afforded under Section 421 of the Internal Revenue Code, the
Participant shall have been an employee of the Company at all times during the
period beginning on the Date of Grant and ending not later than the day three
months before exercise, and, (ii) the Participant shall hold such shares for a
period which is at least two years from the Date of Grant and one year from the

      of
      the Corporation at a purchase price of U.S. $1.50 per share (the “Exercise
      Price”).
      

     

    1.  Term
      of Warrant.
      Subject
      to the other terms and conditions set forth herein, this Warrant shall be
      exercisable, in whole or in part, at any time on or after the date hereof and
      at

      of Warrant.
      This
      Warrant may be exercised, in whole or in part, by the Holder during normal

      to
      the Corporation the following: (i) a duly executed Notice of Exercise (in the

      of Warrant Shares specified in the Notice of Exercise by cash, wire transfer
      of
      immediately available funds to a bank account specified by the Corporation,
      or

      loss, theft or destruction).

     

    3.  Registration
      and Other Rights.

     

    (a)  In

      event that the Corporation files a registration statement with the Securities
      and Exchange Commission covering the sale of its shares of Common Stock (other
      than a registration statement on Form S-4, S-8 or similar form), then the Holder
      shall have the right to require the Corporation to register the resale of the
      Warrant Shares on such registration statement, provided

      if
      such registration is underwritten, the inclusion of such shares shall be subject

      further
      that the
      inclusion of Warrant Shares on any registration statement shall be subject

      of less than all of the Warrant Shares represented hereby, prior to any such
      registration, the Holder shall request that the Company issue in exchange
      therefore new warrants representing the Warrant Shares in such denominations
      as
      the Holder shall request; provided, however, that no such certificate
      representing any Warrant Shares being registered shall also represent Warrant
      Shares not being registered.

      of its then outstanding Common Stock, (A) securities of the Corporation of
      a
      class other than Common Stock, (B) rights, warrants or options (individually,
      a
“Right”
and
      collectively, the “Rights”)
      to
      acquire any securities of the Corporation (including Common Stock) or (C)
      evidences of its indebtedness or assets, or (ii) issues any dividend or other
      similar distribution (a “Secondary
      Extraordinary Dividend”)

      such securities in the form of securities of the Corporation (including Common
      Stock) (any securities (other than Rights) issued as an Extraordinary Dividend
      or Secondary Extraordinary Dividend or issued upon exercise of any Rights issued
      as an Extraordinary Dividend or Secondary Extraordinary Dividend shall be
      referred to as “Dividend
      Securities”):

     

    (i)  this
      Warrant shall thereafter be exercisable for (1) the original number of shares
      of
      Common Stock (subject to adjustment as herein provided), (2) such Dividend
      Securities and Rights as would theretofore have been issued in respect of such
      shares (adjusted as herein provided) had such shares been outstanding at the
      time of such Extraordinary Dividend, and (3) any Dividend Securities that would
      theretofore have been issued as a Secondary Extraordinary Dividend in respect
      of
      such Dividend Securities had such Dividend Securities been outstanding at the
      time of such Secondary Extraordinary Dividend; and

     

    (ii)  any
      Right
      issued as an Extraordinary Dividend or a Secondary Extraordinary Dividend shall
      (1) expire upon the later of (a) the original expiration date of such Right
      or
      (b) the 180th day following the exercise of this Warrant, and (2) be exercisable
      for (a) the Dividend Securities issuable upon exercise of such Right and (b)
      any
      property theretofore issued as a Secondary Extraordinary Dividend in respect
      of
      such Dividend Securities.

     

    (c)  In
      the
      event that at any time while this Warrant is outstanding, the Corporation shall
      offer to sell to all of the holders of Common Stock as a class, rights or
      options to purchase Common Stock or rights or options to purchase any stock
      or
      securities convertible into or exchangeable for Common Stock (such exchangeable
      or convertible stock or securities being herein called “Convertible
      Securities”),
      whether or not such rights or options are immediately exercisable, and the
      price
      per share for which Common Stock is issuable upon the exercise of such rights
      or
      options or upon conversion or exchange of such Convertible Securities
      (determined by dividing (i) the total amount received or receivable by the
      Corporation upon issuance and sale of such rights or options, plus the aggregate
      amount of additional consideration payable to the Corporation upon the exercise
      of all such rights or options, plus, in the case of rights or options which
      relate to Convertible Securities, the aggregate amount of additional
      consideration, if any, payable upon the conversion or exchange of all such
      Convertible Securities, by (ii) the total maximum number of shares of Common
      Stock issuable upon the exercise of all such rights or options or upon the
      conversion or exchange of all such Convertible Securities issuable upon the
      exercise of all such rights or options) shall be less than the Exercise Price
      in
      effect immediately prior to the initial sale of any such rights or options,
      the
      Corporation shall offer to sell to the Holder, at the price and upon the terms
      at which such rights or options are offered to holders of its Common Stock,
      such
      number of such rights or options as the Holder would have been entitled to
      purchase had the Holder exercised this Warrant immediately prior to the
      commencement of the offering of such rights or options.

    4.  Issuance
      of Shares; No Fractional Shares of Scrip.

     

    Certificates
      for shares of Common Stock purchased hereunder shall be delivered to the Holder
      hereof by the Corporation's transfer agent at the Corporation's expense within
      a
      reasonable time after the date on which this Warrant shall have been exercised
      in accordance with the terms hereof. Each certificate so delivered shall be
      in
      such denominations as may be requested by the Holder hereof and shall be
      registered in the name of the Holder or, subject to applicable laws, such other
      name as shall be requested by the Holder. If, upon exercise of this Warrant,
      fewer than all of the Warrant Shares evidenced by this Warrant are purchased
      prior to the Expiration Time, one or more new warrants substantially in the
      form
      of, and on the terms in, this Warrant will be promptly issued for the remaining
      number of Warrant Shares not purchased upon exercise of this Warrant. The
      Corporation hereby represents and warrants that all Warrant Shares which may
      be
      issued upon the exercise of this Warrant will, upon such exercise, be duly
      and
      validly authorized and issued, fully paid and nonassessable and free from all
      taxes, liens and charges in respect of the issuance thereof (other than liens
      or
      charges created by or imposed upon the Holder of the Warrant Shares). The
      Corporation agrees that the shares of Common Stock so issued shall be and will
      be deemed to be issued to such Holder as the record owner of such shares as
      of
      the close of business on the date on which this Warrant shall have been
      surrendered for exercise in accordance with the terms hereof, notwithstanding
      that the transfer books of the Corporation shall then be closed or certificates
      representing such shares of Common Stock shall not then have been actually
      delivered to the Holder. No fractional shares or scrip representing fractional
      shares shall be issued upon the exercise of this Warrant. With respect to any
      fraction of a share called for upon the exercise of this Warrant, an amount
      equal to such fraction multiplied by the then current price at which each share
      may be purchased hereunder shall be paid in cash to the Holder of this
      Warrant.

     

    5.  Charges,
      Taxes and Expenses.

     

    Issuance
      of certificates for shares of Common Stock upon the exercise of this Warrant
      shall be made without charge to the Holder hereof for any issue or transfer
      tax
      or other incidental expense in respect of the issuance of such certificate,
      all
      of which taxes and expenses shall be paid by the Corporation, and such
      certificates shall be issued in the name of the Holder of this Warrant or in
      such name or names as may be directed by the Holder of this Warrant; provided,
      however, that in the event certificates for shares of Common Stock are to be
      issued in a name other than the name of the Holder of this Warrant, this Warrant
      when surrendered for exercise shall be accompanied by an Assignment Form (as
      defined below) duly executed by the Holder hereof.

     

    6.  No
      Rights as Stockholders.

     

    This
      Warrant does not entitle the Holder hereof to any voting rights or other rights
      as a stockholder of the Corporation prior to the exercise hereof.

     

    7.  Exchange
      and Registry of Warrant.

     

    This
      Warrant is exchangeable, upon the surrender hereof by the registered Holder
      at
      the above mentioned office or agency of the Corporation, for a new Warrant
      of
      like tenor and dated as of such exchange. The Corporation shall maintain at
      the
      above-mentioned office or agency a registry showing the name and address of
      the
      registered Holder of this Warrant. This Warrant may be surrendered for exchange,
      transfer or exercise, in accordance with its terms, at such office or agency
      of
      the Corporation, and the Corporation shall be entitled to rely in all respects,
      prior to written notice to the contrary, upon such registry.

    8.  Loss,
      Theft, Destruction or Mutilation of Warrant.

     

    Upon
      receipt by the Corporation of evidence reasonably satisfactory to it of the
      loss, theft, destruction or mutilation of this Warrant and in case of loss,
      theft or destruction of indemnity or security reasonably satisfactory to it,
      and
      upon reimbursement to the Corporation of all reasonable expenses incidental
      thereto, and upon surrender and cancellation of this Warrant, if mutilated,
      the
      Corporation will make and deliver a new Warrant of like date, tenor and
      denomination, in lieu of this Warrant.

     

    9.  Saturdays,
      Sundays and Holidays.

     

    If
      the
      last or appointed day for the taking of any action or the expiration of any
      right required or granted herein shall be a Saturday
      or a Sunday or a legal holiday, then such action may be taken or such right
      may
      be exercised on the next succeeding
      day not a Saturday, Sunday or legal holiday.

     

    10.  Merger,
      Sale of Assets, Etc.

     

    If
      at any
      time the Corporation proposes to merge or consolidate with or into any other
      corporation, effect any reorganization, or sell or convey all or substantially
      all of its assets to any other entity, then, as a condition of such
      reorganization, consolidation, merger, sale or conveyance, the Corporation
      or its
      successor, as the case may be, shall enter into a supplemental
      agreement to make lawful and adequate provision whereby the Holder shall have
      the right to receive, upon exercise of the Warrant by exchanging the Warrant
      for
      the kind and amount of equity securities, property, cash, or any combination
      thereof, which would have been received upon such reorganization, consolidation,
      merger, sale or conveyance by a Holder of a number of shares of common stock
      equal to the number of shares issuable upon exercise of the Warrant immediately
      prior to such reorganization, consolidation, merger, sale or conveyance.

     

    11.  Subdivision,
      Combination, Reclassification, Conversion, Etc.

     

    If
      the
      Corporation at any time shall by subdivision, combination, reclassification
      of
      securities or otherwise, change the Warrant Shares into the same or a different
      number of securities of any class or classes, this Warrant shall thereafter
      entitle the Holder to acquire such number and kind of securities as would have
      been issuable in respect of the Warrant Shares (or other securities which were
      subject to the purchase rights under this Warrant immediately prior to such
      subdivision, combination, reclassification or other change) as the result of
      such change if this Warrant had been exercised in full for cash immediately
      prior to such change. The Exercise Price hereunder shall be adjusted if and
      to
      the extent necessary to reflect such change. If the Warrant Shares or other
      securities issuable upon exercise hereof are subdivided or combined into a
      greater or smaller number of shares of such security, the number of shares
      issuable hereunder shall be proportionately increased or decreased, as the
      case
      may be, and the Exercise Price shall be proportionately reduced or increased,
      as
      the case may be, in both cases according to the ratio which the total number
      of
      shares of such security to be outstanding immediately after such event bears
      to
      the total number of shares of such security outstanding immediately prior to
      such event. The Corporation shall send the Holder prompt written notice by
      registered mail, postage prepaid, of any change in the type of securities
      issuable hereunder, any adjustment of the Exercise Price for the securities
      issuable hereunder, and any increase or decrease in the number of shares
      issuable hereunder, which notice shall be accompanied by an officer’s
      certificate setting forth the number of Warrant Shares purchasable upon the
      exercise of this Warrant and the Exercise Price after such adjustment and
      setting forth a brief statement of the facts requiring such adjustment and
      the
      computation thereof, which officer’s certificate shall be conclusive evidence of
      the correctness of any adjustment absent manifest error.

    12.  Notice

     

    In
      case,
      at any time the Corporation shall propose:

     

    (a)  to
      declare a dividend (or any other distribution) on shares of Common Stock in
      shares of Common Stock or make any other distribution to all holders of Common
      Stock; or

     

    (b)  to
      issue
      any rights, warrants or other securities to all holders of Common Stock
      entitling them to subscribe for or purchase shares of Common Stock or of any
      other subscription rights or warrants; or

     

    (c)  to
      effect
      any reclassification of the Common Stock, any consolidation, merger or binding
      share exchange to which the Corporation is a party, or the sale or transfer
      of
      all or substantially all of the assets of the Corporation; or

     

    (d)  to
      effect
      any voluntary or involuntary dissolution, liquidation or winding up of the
      Corporation; or

     

    (e)  to
      take
      any other action which would cause an adjustment to the Exercise Price;

     

    (f)  then,
      the
      Corporation shall cause to be mailed to the Holder at least 15 days before
      the
      date hereinafter specified, a notice stating (i) the date on which a record
      is
      to be taken for the purpose of such dividend, distribution, rights or warrants,
      or, if a record is not to be taken, the date as of which the holders of shares
      of Common Stock of record to be entitled to such dividend, distribution, rights
      or warrants are to be determined, (ii) the date on which any such
      reclassification, consolidation, merger, binding share exchange, sale, transfer,
      dissolution, liquidation or winding up is expected to become effective, and
      the
      date as of which it is expected that holders of shares of Common Stock of record
      shall be entitled to exchange their shares for the applicable consideration,
      deliverable upon such reclassification, consolidation, merger, binding share
      exchange, sale, transfer, dissolution, liquidation or winding up, or (iii)
      the
      date of such action which would require an adjustment to the Exercise
      Price.

     

    13.  Transferability; Compliance
      with Securities Laws.

     

    (a)  This
      Warrant may not be transferred or assigned in whole or in part without
      compliance with all applicable federal and state securities laws by the
      transferor and transferee (including the delivery of investment representation
      letters and legal opinions reasonably satisfactory to the Corporation, if
      requested by the Corporation). Subject to such restrictions, prior to the
      Expiration Time, this Warrant and all rights hereunder are transferable by
      the
      Holder hereof, in whole or in part, at the office or agency of the Corporation.
      Any such transfer shall be made in person or by the Holder's duly authorized
      attorney, upon surrender of this Warrant together with the Assignment Form
      attached hereto properly endorsed (the “Assignment
      Form”).

    (b)  The
      Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant
      and
      the Warrant Shares issuable upon exercise hereof are being acquired solely
      for
      the Holder's own account and not as a nominee for any other party, and for
      investment, and that the Holder will not offer, sell or otherwise dispose of
      this Warrant or any Warrant Shares to be issued upon exercise hereof except
      under circumstances that will not result in a violation of the Securities Act
      of
      1933, as amended, or any state securities laws. Upon exercise of this Warrant,
      the Holder shall, if requested by the Corporation, confirm in writing, in a
      form
      satisfactory to the Corporation, that the Warrant Shares so purchased are being
      acquired solely for the Holder's own account and not as a nominee for any other
      party, for investment, and not with a view toward distribution or
      resale.

     

    (c)  Until
      the
      Warrant Shares have been registered under the Securities Act of 1933, as
      amended, this Warrant may not be exercised except by (i) the original purchaser
      of this Warrant from the Corporation or (ii) an “accredited investor” as defined
      in Rule 501(a) under the Securities Act of 1933, as amended. Each certificate
      representing the Common Stock or other securities issued in respect of the
      Warrant Shares upon any stock split, stock dividend, recapitalization, merger,
      consolidation or similar event, shall be stamped or otherwise imprinted with
      a
      legend substantially in the following form (in addition to any legend required
      under applicable securities laws):

     

    THE
      SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND
      NOT
      WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF, AND
      HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
      SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
      UNLESS THE SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
      DELIVERY REQUIREMENTS OF SAID ACT.

     

    Once
      the
      Warrant Shares have been registered under the Securities Act of 1933, as
      amended, no such restrictive legend shall be required on any securities issued
      in respect of the Warrant Shares, unless otherwise required under the Securities
      Act of 1933, as amended.

     

    14.  Reservation
      of Shares of Common Stock.

     

    The
      Corporation hereby agrees that during the period that this Warrant is
      outstanding, the Corporation will reserve from its authorized and unissued
      Common Stock and other securities, solely for the purpose of providing for
      the
      exercise of the rights to purchase all Warrant Shares granted pursuant to this
      Warrant, such number of shares of Common Stock, Dividend Securities and Rights
      to permit the exercise in full of this Warrant.

     

    15.  Governing
      Law.

     

    This
      Warrant shall be governed by and construed in accordance with the laws of the
      State of Delaware. The Corporation irrevocably consents to the jurisdication
      of
      the courts of the State of California and of any federal court located in such
      State in connection with any action or proceeding arising out of or relating
      to
      this Warrant, any document or instrument delivered pursuant to, in connection
      with or simultaneously with this Warrant, or a breach of this Warrant or any
      such document or instrument. In any such action or proceeding, the Company
      waives personal service of any summons, complaint or other process.
