                              CREDIT ACCOMMODATIONS

                  2.1 The Revolving Credit Facility. The Bank shall make
available to the Borrower, a Revolving Credit Facility in the maximum principal
amount of Twenty Five Million Dollars ($25,000,000.00) (the "REVOLVING CREDIT
COMMITMENT"), upon the terms and conditions set forth herein.

                      (a) Generally. At any time and from time to time during
the period commencing on the Closing Date and ending on the Revolving Credit
Termination Date, upon the request of the Borrower, and provided the Borrower is
in compliance with the conditions precedent to making Revolving Credit Loans
contained in Section 4.2 of this Agreement, the Bank shall provide to the
Borrower a loan or loans, which shall be used by the Borrower for general
corporate purposes, including working capital. The Borrower may use the
Revolving Credit Facility during the period referred to in the preceding
sentence by borrowing, repaying and reborrowing in accordance with the terms of
this Agreement. The aggregate outstanding principal of the Revolving Credit
Loans at any time shall not exceed the Revolving Credit Commitment. If at any
time, the aggregate outstanding principal balance of all Revolving Credit Loans
exceeds the Revolving Credit Commitment, then, without any requirement or demand

amount of such excess. Upon the Revolving Credit Termination Date, unless the
same has been extended by written agreement between the Bank and the Borrower,
the Revolving Credit Commitment shall terminate, all Revolving Credit Loans
shall immediately mature and all Obligations under the Revolving Credit Facility
shall be immediately due and payable in full.

                      (b) Letters of Credit.

                          (i) Generally. In addition to making Loans to the
Borrower under the Revolving Credit Facility as provided in Section 2.1(a)
hereof, the Bank shall, upon the request of the Borrower and subject to the
terms of this Agreement, also issue one or more letters of credit ("LETTERS OF
CREDIT") for the account of the Borrower provided all such Letters of Credit
shall not in the aggregate exceed Ten Million Dollars ($10,000,000.00). All
amounts drawn under Letters of Credit shall be deemed to be loans made under the
Revolving Credit Facility and evidenced by the Revolving Credit Note, and the
amount available to be borrowed under the Revolving Credit Facility shall be
reduced by the aggregate amounts drawn and available to be drawn at any time
under all outstanding Letters of Credit. In no event shall the aggregate amount
available to be drawn on all outstanding Letters of Credit plus the outstanding
principal balance of Revolving Credit Loans exceed the Revolving Credit
Commitment. The duration of any Letters of Credit shall not extend beyond the
Revolving Credit Termination Date without the written consent of the Bank.

                          (ii) Issuance of Letters of Credit. Subject to the
provisions of Section 2.1(b)(1), the Bank shall issue Letters of Credit for the
account of the Borrower, or a Subsidiary provided that the Borrower (i) provides
a written request for each such Letter of Credit specifying the terms thereof,
including, without limitation, the amount and the name and address of the
beneficiary of such Letter of Credit; (ii) executes and delivers to the Bank an
application for each such Letter of Credit pursuant to the form provided for
such purpose by the Bank; and (iii) executes and delivers to the Bank such other
documents and instruments which the Bank, in its sole and absolute discretion,
deems reasonable and necessary. The Borrower shall pay to the Bank a per annum
fee in connection with the issuance of each Letter of Credit equal to seventy
five basis points (.75%) and all transactional and customary fees required by
the Bank in connection with the issuance of each Letter of Credit hereunder,
including, without limitation, the Bank's standard remittance, transfer and
issuance fees, which fees may be deducted by the Bank from the Borrower's
account as such fees are incurred.

                      (c) Revolving Credit Note. The obligation of the Borrower
to repay the aggregate outstanding principal of the Revolving Credit Loans made
by the Bank and to pay accrued interest thereon shall be evidenced by a
promissory note to the Bank, to be executed and delivered to the Bank
concurrently with the execution and delivery of this Agreement (the "REVOLVING
CREDIT NOTE").

                                       7
<PAGE>

                      (d) Facility Fee. The Borrower shall pay to the Bank a
quarterly unused line fee in the amount of twenty basis points (.20%) with the
first unused line fee payable in arrears on October 1, 2006 and thereafter, on
the first Business Day of each calendar quarter and shall be calculated by the
Bank on the average daily unused amount of the Revolving Loan Commitment for the
preceding calendar quarter as long as this Agreement remains in effect.

                  2.2 Interest. (a) Interest shall accrue on the unpaid
principal balance of each Revolving Credit Loan from the date of such Loan at a
rate per annum equal to (i) the Variable Rate; or (ii) the LIBOR-Based Rate for
Revolving Credit Loans, as selected by the Borrower in accordance herewith
(each, an "INTEREST RATE"). The Interest Rate for each Interest Period shall
accrue each day during such Interest Period commencing on and including the
first day to but excluding the last day. There shall be no more than one
Interest Rate for a Loan in effect at any time. When the Variable Rate is
selected for a Revolving Credit Loan, it shall be adjusted from time to time,
effective as of the date of each change in the Bank's LIBOR Market Index Rate,
as applicable, and shall continue to apply until another Interest Rate option is
selected for that Loan. When the LIBOR-Based Rate is selected for a Revolving
Credit Loan, such rate shall be fixed for each Interest Period for which it is
determined and shall apply for that Loan until another Interest Rate option is
selected for that Loan. The Borrower shall give the Bank irrevocable telephonic
notice (confirmed in writing by a Notice of Borrowing as set forth on Exhibit A)
of each proposed Revolving Credit Loan or rate conversion not later than 12:00
p.m. local time at the office of the Bank (i) on the same Business Day as each
proposed Loan at or rate conversion to the Variable Rate and (ii) at least two
(2) Business Days before each proposed Loan at or rate conversion to the
LIBOR-Based Rate. Each such notice shall specify (x) the date of such Loan or
rate conversion, which shall be a Business Day and, in the case of a conversion
from the LIBOR-Based Rate, shall be the last day of an Interest Period, (y) the
amount of each advance or the amount to be converted, and (z) the Interest Rate
selected by the Borrower. Notices received after 11:00 a.m. local time at the
office of the Bank shall be deemed received on the next Business Day. Each
LIBOR-Based Rate Loan shall be in minimum amounts of not less than One Million
Dollars ($1,000,000.00) with increments of One Hundred Thousand Dollars
($100,000.00) and each Variable Rate Loan shall be in minimum amount of One
Hundred Thousand Dollars ($100,000). Notwithstanding anything to the contrary
contained herein, the Borrower may not elect application of a rate of interest
to any Loan if such election would require the Bank to administer concurrently
more than three LIBOR-Based Rate Loans for the Revolving Credit Loans. All
determinations and quotations of rate by the Bank hereunder shall be conclusive
and binding upon the Borrower, in the absence of demonstrable error.

                      (b) Default Rate. Upon the occurrence and during the
continuance of any Event of Default, all Loans shall automatically terminate and
be automatically converted to Loans bearing interest at the Default Rate, and
shall be subject to the payment of all amounts then due with respect to such
termination under Section 2.2(e) of this Agreement.

                      (c) Payment of Interest. The Borrower shall pay interest
on the Variable Rate Loans in arrears on the last day of each consecutive
calendar month and, on LIBOR-Based Rate Loans, on the earlier of last day of
each Interest Period applicable thereto or quarterly (based on a calendar
quarter). All accrued but unpaid interest under the Note shall also be payable,
without demand, on the maturity thereof (whether by its stated terms, or upon
prepayment, acceleration or otherwise). Interest shall be computed from the
actual number of days elapsed and on the basis of a year of 360 days.

                                       8

                      (d) Funding Losses. The Borrower shall indemnify the Bank
against the Bank's loss or expense as a consequence of (i) the Borrower's
failure to make any payment when due on a LIBOR-Based Rate Loan, (ii) any
payment, prepayment or conversion of any LIBOR-Based Rate Loan on a date other
than the date set forth in subsection (c) above, or (iii) any failure to make a
borrowing or conversion after giving notice thereof ("INDEMNIFIED LOSS OR
EXPENSE"). The amount of such Indemnified Loss or Expense shall be determined by
the Bank based upon the assumption that the Bank funded 100% of that portion of
the Loan respectively in the applicable London interbank or domestic certificate
of deposit market.

                      (e) Determinations. In making the determinations
contemplated by this Section, the Bank may make such estimates, assumptions,
allocations and the like that it, in good faith, determines to be appropriate.
All such determinations shall be final, binding and conclusive upon the
Borrower, except to the extent of any demonstrable error in computation or
transmission. The Bank shall furnish to the Borrower, upon request, a
certificate outlining in reasonable detail the computation of any amounts
claimed under this Section and the assumptions underlying such computations,
provided that the failure to deliver a certificate shall not affect the Bank's
right to such amounts.

                  2.3 Borrowing, Payments and Computations. The Bank shall
maintain on its books the account or accounts previously established by the
Borrower with the Bank (collectively, the "LOAN ACCOUNT") to which it shall
charge all Loans to or for the benefit of the Borrower pursuant to the terms of
this Agreement, including, without limitation, all advances to the Borrower
under the Loans and to which it shall credit, in accordance with the terms
hereof, each payment made by the Borrower. The records of the Bank with respect
to the Loan Account shall be presumed to correctly evidence the outstanding
principal balance of all Loans under this Agreement, except to the extent of any
error in such records. All Loans shall be credited by the Bank directly to the
Loan Account. All amounts payable by the Borrower to the Bank under this
Agreement or the Note with respect to principal, interest and fees shall be paid
to the Bank in immediately available funds at the address of the Bank set forth
in Section 9.2 hereof or at such other address of which the Bank shall give
notice to the Borrower pursuant to Section 9.2 hereof. The Bank shall have the
right to debit the Loan Account for the payment of principal, interest and fees
hereunder. All payments under the Note shall be applied first to the payment of
interest due and payable thereunder and then to the reduction of the outstanding
principal balance thereof.

                  2.4 Prepayments. Except for any charge that may be required by
Section 2.2(d) of this Agreement with respect to the prepayment of a LIBOR-Based
Rate Loan, the Borrower may prepay in whole or in part, any portion of any Loan
without premium or additional charge. All prepayments of any Loan shall be
accompanied by the payment of accrued interest on the amount of such prepayment
to the date thereof. The Borrower may make payments and prepayments of the Loans
in whole or in part at any time and from time to time upon notification to the
Bank not later than 12:30 p.m. Philadelphia, Pennsylvania time on the date of
the proposed payment or prepayment.

                  2.5 Requirements of Law. In the event that after the date
hereof, any change in any law, regulation or treaty or in the interpretation or
application thereof or compliance by the Bank with any request or directive
(whether or not having the force of law) from any central bank or other
governmental authority, agency or instrumentality:

                      (a) subjects or shall subject the Bank to any tax of any
kind whatsoever with respect to this Agreement, the Loans or the issuance or
maintenance of Letters of Credit hereunder, or changes the basis of taxation of
payments to the Bank of principal, interest or any other amount payable
hereunder (except for Excluded Taxes);

                      (b) imposes, modifies or holds or shall impose, modify or
hold applicable any reserve, special deposit, compulsory loan or similar
requirement against assets held by, or deposits or other liabilities in or for
the account of, advances or loans by, or other credit extended by, or any other
acquisition of funds by, any office of the Bank, which reserve, special deposit,
compulsory loan or similar requirement is not otherwise included in
determination of the interest rate hereunder;

                      (c) imposes or shall impose on the Bank any other
condition; and the result of any of the foregoing is to, directly or indirectly,
increase the cost to the Bank of making, renewing or maintaining advances or
extensions of credit or to reduce any amount receivable thereunder then, in any
such case, the Borrower shall promptly pay the Bank, upon its demand, any
additional amounts necessary to compensate the Bank for such additional cost or
reduced amount receivable. If the Bank becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the Borrower of
the event by reason of which it has become so entitled. The good faith
determination as to any additional amounts payable pursuant to the foregoing
sentence by the Bank shall be conclusive in the absence of manifest error.

                      (a) Upon the occurrence of and during the continuance of
any one or more Events of Default, the Bank may, in its sole discretion, refuse
to make any further advances or Loans to the Borrower;

                      (b) Automatically upon the occurrence of any Event of
Default described in Section 7.7 of this Agreement, and in the sole discretion
of the Bank upon the occurrence of and during the continuance of any other Event
of Default, the unpaid principal balance of all Loans, all interest and fees
accrued and unpaid thereon, and all other amounts and Obligations payable by the
Borrower under this Agreement and the other Loan Documents shall immediately
become due and payable in full, all without protest, presentment, demand, or
further notice of any kind to the Borrower, all of which are expressly waived by
the Borrower and the Loans shall thereafter accrue interest at the Default Rate;

                      (c) If any of the Obligations shall be due and payable or

available to it, without prior notice to the Borrower, to apply toward and
set-off against and apply to the then unpaid balance of the Note and the other
Obligations any items or funds held by the Bank, any and all deposits (whether
general or special, time or demand, matured or unmatured, fixed or contingent,
liquidated or unliquidated) now or hereafter maintained by the Borrower for its
own account with the Bank, and any other indebtedness at any time held or owing
by the Bank to or for the credit or the account of the Borrower. If any of the
Obligations shall be due and payable or any one or more Events of Default shall
have occurred and be continuing, the Bank is hereby authorized to charge any
such account or indebtedness for any amounts due to the Bank. Such right of
set-off shall exist whether or not the Bank shall have made any demand under
this Agreement, the Notes or any other Loan Document and whether or not the
Notes and the other Obligations are matured or unmatured. The Borrower hereby
confirms the Bank's right of set-off, and nothing in this Agreement shall be
deemed any waiver or prohibition of such right of set-off.

remedies as are available to the Bank in respect thereof under applicable law,

DOCTRINE OF FORUM NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY
PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS AGREEMENT. BORROWER ACKNOWLEDGES

Borrower's affairs as the Bank possesses. The Bank shall give notice to the
Borrower of the grant of such participations; however, the failure to give such
notice shall not affect any of the Bank's rights hereunder.

Agreement that is held to be inoperative, unenforceable, voidable, or invalid in

provisions of this Agreement are declared to be severable.

SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE COURT AND NOT A JURY.

                  9.15 Indemnification.

                      (a) If, after receipt of any payment of all or any part of
the Obligations, the Bank is compelled to surrender such payment to any Person
or entity for any reason (including, without limitation, a determination that
such payment is void or voidable as a preference or fraudulent conveyance, an
impermissible setoff, or a diversion of trust funds), then this Agreement and
the other Loan Documents shall continue in full force and effect, and the
Borrower shall be liable for, and shall indemnify, defend and hold harmless the
Bank with respect to the full amount so surrendered.

                      (b) The Borrower shall indemnify, defend and hold harmless
the Bank with respect to any and all claims, expenses, demands, losses, costs,
fines or liabilities of any kind, including reasonable attorneys' fees and
costs, arising from or in any way related to (i) acts or conduct of the Borrower
under, pursuant to or related to this Agreement and the other Loan Documents,
(ii) the Borrower's breach or violation of any representation, warranty,
covenant or undertaking contained in this Agreement or the other Loan Documents,
and (iii) the Borrower's failure to comply with any or all laws, statutes,
ordinances, governmental rules, regulations or standards, whether federal,
state, or local, or court or administrative orders or decrees, including without
limitation those resulting from any Hazardous Materials or dangerous
environmental condition within, on, from, related to or affecting any real
property owned or occupied by the Borrower, unless resulting from the acts or
conduct of the Bank constituting gross negligence or willful misconduct.

termination of this Agreement and the other Loan Documents and shall be and
remain effective, notwithstanding the payment of the Obligations, the
cancellation of the Note, the release of any Encumbrance securing the
Obligations or any other action which the Bank may have taken in reliance upon
its receipt of such payment. Any cancellation of the Note, release of any
Encumbrance or other such action shall be deemed to have been conditioned upon

                             CASH INVESTMENT POLICY

OVERVIEW

Fuel-Tech NV {FTNV} recognizes that due to the nature of its operating Business
Segments, excess cash reserves will arise from time to time. Cash reserves are
defined as the balance of funds available after having given consideration to 1)
the amount of funds necessary to meet the operating liquidity needs of the
business, and 2) those funds required for specific legal, contractual or
long-term investment requirements.

The remainder of this document defines the details of the Cash Investment Policy
(the Policy) as follows: Adoption, Scope, Investment Objectives, Authorized
Investments and Allowable Credit Rating, investment Allocation, Authorized
Broker/Dealers, Monitoring of Objectives and Reporting. Again, this Policy will
exclude all specifically identified Cash requirements for any specific legal,
contractual or long-term investment requirements,

ADOPTION

It is the responsibility of the Board of Directors to adopt the Policy as
written and to approve all subsequent changes to the Policy. This Policy will be
reviewed on a recurring basis as defined further below based on input from
FTNV's Chief Financial Officer, its investment advisors and or by other
qualified, approved, and authorized FTNV Finance personnel.

SCOPE

This Policy applies to FTNV and its consolidated subsidiaries, and to all
personnel authorized to engage in cash investment transaction as defined in this
Policy {Addendum A).

INVESTMENT OBJECTIVES

The primary objectives of the Policy are to provide safety and liquidity for
excess cash balances, and only after these requirements are clearly met, to seek
optimum yields. Below, the key financial objectives of the FTNV cash investment
portfolio are defined:

Preservation of Capital

Preserve the principal value of the investment. FTNV shall consider the safety
of its capital as the primary objective in investment activities. Each
investment transaction shall seek to first ensure that capital losses are
avoided, whether they are from security default or the erosion of market value.


Maintain Liquidity

Maintain an investment portfolio that provides access to the cash or cash
equivalents necessary to meet the immediate short-term operating needs of FTNV.
Liquidity needs shall be anticipated by matching investment maturities with
forecasted cash flow requirements and by investing in securities with active
secondary markets.



                                                                          Page 3

management fees if applicable) consistent with the investment objectives set

by FTNV's Chief Financial Officer on a recurring basis.

Specific Obligations and Future Needs

requirements of FTNV and its subsidiaries.

INVESTMENT ALLOCATION

To achieve FTNV's investment objective, all excess cash balances shall be
divided into two separate pools. The pools shall be identified as the Current
investment Pool and the Intermediate-Term investment Pool. The investment time
frame for the Current investment Pool is zero to three months while the time
frame for the Intermediate-Term Investment Pool is four to twelve months.

The purpose of the Current Pool is to provide immediate cash flow to
support the FTNV's operations in the near-term. The percentage of total cash
assets in the Current Pool will be determined by the forecasted cash
requirements of FTNV's operating business segments and an analysis of available
investments and their respective returns.

The purpose of the Intermediate Pool is to invest available cash that is not
required in the near term, but rather, will need to be made available on a
longer term basis. The percentage of total cash assets in the Current Pool will
be determined by the forecasted cash requirements of FTNV's operating business
segments and an analysis of available investments and their respective returns.

AUTHORIZED BROKER DEALERS and QUALIFICATIONS

Listed in Addendum B below are the firms in which FTNV's authorized investment
personnel can invest the available cash reserves. All authorized investment
firms must maintain a net worth of not less than $1 billion and they must be
members in good standing of the Securities Investor Protection Corporation
(SPIC).

MONITORING OF OBJECTIVES AND RESULTS

ALL objectives in this Policy are in effect until modifications are recommended
by the Chief Financial Officer and approved by the FTNV Board of Directors. The
objectives should be reviewed on an annual basis for their continued
appropriateness, or more often if the need arises.

It is the responsibility of FTNV's authorized investment personnel or authorized
broker dealers to advise the Chief Financial Officer if, at any time, any
specific guideline in this Policy inhibits the achievement of any of the stated
objectives.

All investment decisions are to be made with the approval of the Chief
Financial Officer and two signatures from FTNV's list of authorized investment
personnel must evidence the investment transaction. Further, subsequent to
submission of the investment request to the authorized broker-dealer, the
authorized broker dealer must confirm the transaction with Chief Financial
Officer, or another member of FTNV's authorized investment personnel via e-mail
or phone call. There will be no exceptions to the investment Policy without
prior approval from the Board of Directors.

On a monthly basis, a report summarizing the assets held in the investment
portfolio, and all prior month investment activity, will be provided to the
Chief Financial Officer by the authorized investment personnel listed in
Addendum A.
