                        MANAGEMENT AND SERVICES AGREEMENT

                                  JUNE 1, 1996

         AGREEMENT as of the 1st day of June, 1996 between Clean Diesel
Technologies, Inc., a Delaware Corporation ("CDT"), Fuel Tech, Inc., a
Massachusetts corporation ("FTI"), each with a place of business at 300 Atlantic
Street, Stamford, Connecticut, 06901 U.S.A., Fuel-Tech N.V., a Netherlands
Antilles limited liability company ("FTNV") with a place of business at
Castorweg 22-24, Curacao, N.A., and Fuel Tech Europe Limited, an English company
("FTE") with a place of business at 28a Cadogan Sq., London, SW1 OJH, U.K.

         CDT is an affiliate and FTI and FTE are wholly-owned subsidiaries of
FTNV and each of these parties is desirous of utilizing certain services and
resources of the other and agreeing the terms and conditions for compensation
for the same.

         NOW THEREFORE, the parties agree as follows:

         1. Reimbursement. The parties shall reimburse one another as
provided on Schedule A attached hereto and made a part hereof and
as such Schedule A may be amended from time to time.

         2. Cost. Cost shall be the invoice cost of goods and services including
all taxes (except VAT claimed by the party seeking reimbursement) and other
additional items. The cost of services provided by employees of the parties
shall be calculated on an hourly basis by dividing the sum of the annual wages
and benefits of an employee by 2,080 hours. Benefits shall include any employer
paid item on account of such employment, such as social security, whether or not
received by the employee.

         3. Directors' Fees; Executive Services. With respect to persons who are
directors of both CDT and FTNV, but who are executives or officers of only one
of such companies, directors fees, if any, shall be paid by each company as per
the current remuneration schedule of the entity concerned, but such fees shall
be paid to the company of which the director is an executive or officer unless
waived by such company. Where such a director performs services (not involving
directors meetings or travel and preparation therefor) for a company of which he
is not an executive, the director's employer company shall be paid $1,000 per
day for such services. Additionally, where an executive of one company who is 
not a director provides services for another company and provision for such 
services shall not have been made on Schedule A, a cost reimbursement shall be 
made to the company providing the services based on the principles set out in 
Section 2 above.







Management and Services Agreement as of June 1, 1996, p. 2.

         4. Term; Renewal; Renegotiation. This agreement shall remain in effect
indefinitely unless on or before May 15 in any year CDT or FTNV shall notify the
other in writing of the cancellation thereof. This agreement may be amended from
time to time with the approval of the Board of Directors of CDT or FTNV,
provided, however that amendments, including amendments to Schedule A, in any
period of twelve months not aggregating $5,000 in anticipated charges to a party
may be executed by the Controller or any Vice President or Managing Director of
any party without reference to the Board of Directors.

         5. Governing Law; Arbitration. This agreement shall be governed by the
internal substantive laws of the State of Connecticut, U.S.A. All questions of
the interpretation of this agreement or any claims or disputes hereunder shall
be determined by the binding written agreement of the Chief Executive Officers
of CDT and FTNV, and, if there shall be no such agreement after 60 days from
notice of a written request therefor by CDT or FTNV, then such questions shall
be determined by final, binding arbitration under the then commercial rules of
the American Arbitration Association in the City of Stamford, Connecticut before
a single, neutral arbitrator who shall be a certified public accountant. Any
award in such arbitration may be entered in and enforced by any court having
jurisdiction.

         6. Notices. Notices hereunder shall be made when transmitted or
delivered, if sent by hand or facsimile transmission and acknowledged;
otherwise, notices shall be deemed made five (5) days after being sent, if sent
by first class mail, postage prepaid.

IN WITNESS WHEREOF, the parties hereto have set their hands and seals as of the
date first above written.
