outstanding immediately after such transaction, or (B) a transaction effected to
implement a recapitalization of the Company (or similar transaction) in which no
person acquires more than 20% of the combined voting power of the Company's then
outstanding securities (or if such person so acquiring more than 20% of such
combined voting power is Suez Lyonnaise des Eaux or an

                                      -8-

the Securities Exchange Act of 1934;

          (B) the Executive's investment does not exceed, in the case of any
class of the capital stock of any one issuer, 1% of the issued and outstanding

<PAGE>
 
securities, 1% of the aggregate principal amount thereof issued and outstanding;
and

          (C)  such investment would not prevent, directly or indirectly, the
transaction of business by the Company and/or any of its affiliates with any
state, district, territory or possession of the United States or any
governmental subdivision, agency or instrumentality thereof by virtue of any
statute, law, regulation or administrative practice.

         If, at any time, the provisions of this Section 8(b) shall be
determined to be invalid or unenforceable by reason of being vague or
unreasonable as to area, duration or scope of activity, this Section 8(b) shall
be considered severable and shall become and shall be immediately amended solely
with respect to such area, duration and scope of activity as shall be determined
to be reasonable and enforceable by the court or other body having jurisdiction
over the matter and the Executive agrees that this Section 8(b) as so amended
shall be valid and binding as though any invalid or unenforceable provision had
not been included herein. Except as provided in this Section 8 and in Section 3,
nothing in this Agreement shall prevent or restrict the Executive from engaging
in any business or industry in any capacity.

         For purposes of clause (ii) of this Section 8(b), the term "prospective
customer" shall mean any entity, business or individual included on a list of
prospective customers provided to the Executive by the Company within 15 days
following his Date of Termination, which list contains the names of those
entities, businesses and individuals with whom the Company had been in contact
prior to the Executive's Date of Termination for purposes of establishing a
customer relationship therewith.  Any entity, business or individual not
appearing on the aforementioned list of prospective customers due to the failure
of the Executive to advise the Company of such contact shall be considered a
"prospective customer" for purposes of clause (ii) of this Section 8(b).

         (c)  Public Support and Assistance.  The Executive agrees that
              ------------------------------
following any termination of his employment hereunder by the Company, the
Executive shall not disclose or cause to be disclosed any negative, adverse or
derogatory comments or information of a substantial nature about the Company or
its management, or about any product or service provided by the Company, or
about the Company's prospects for the future (including any such comments or
information with respect to affiliates of the Company). The Company and/or any

Executive's position as an officer or employee of the Company, and in any such
instance, the Executive shall provide such assistance, cooperation or testimony
and the Company shall pay the Executive's reasonable costs and expenses in
connection therewith; in addition, if such assistance, cooperation or testimony
requires more than a nominal commitment of the Executive's time, the Company
shall compensate the Executive for such time at a per diem rate derived from the
Executive's Base Salary at the time of the Executive's Date of Termination.

        (d)  Nondisclosure of Confidential Information.  During the Term, the
             -----------------------------------------
Executive shall hold in a fiduciary capacity for the benefit of the Company and
its affiliates all Confidential Information (as defined below). After
termination of the Executive's employment with the Company, the Executive shall
keep secret and confidential all Confidential Information and shall not use or
disclose to any third party in any fashion or for any purpose whatsoever, any
Confidential Information. As used herein, "Confidential Information" shall mean
any information regarding this Agreement, or any other information regarding the
Company or its affiliates which is not available to the general public, and/or
not generally known outside the Company or any such affiliate, to which the
Executive has or shall have had access at any time during the course of the
Executive's employment with the Company, including, without limitation, any
information relating to the Company's (and its affiliates'):

                  (i) business, operations, plans, strategies, prospects or
objectives;

                 (ii) products, technologies, processes,  specifications,
research and development operations or plans;

                (iii) customers and customer lists;

                 (iv) sales, service, support and marketing practices and
operations;

                  (v) financial condition and results of operations;

                  (vi) operational strengths and weaknesses; and

                 (vii) personnel and compensation policies and procedures.

Notwithstanding the foregoing provisions of this Section 8, the Executive may
discuss this Agreement with the members of the Executive's immediate family and
with the Executive's personal legal and tax advisors.

              (e)  Specific Performance.  Without intending to limit the
                   --------------------
remedies available to the Company, the Executive agrees that damages at law
would be an insufficient remedy to the Company in the event that the Executive
violates any of the provisions of this Section 8, and that the Company may apply
for and, upon the requisite showing, have injunctive relief in any court of
competent jurisdiction to restrain the breach or threatened breach of or
otherwise to specifically enforce any of the covenants contained in this Section
8.

        9.  Excise Tax Gross-Up Payment.  If any payments to the Executive by
            ---------------------------                                      
the Company under this Agreement ("Payments") are subject to the tax (the
"Excise Tax") imposed by Section 4999 of the Code, the Company shall pay to the
Executive an additional amount (the "Gross-Up Payment") such that the net amount
retained by the Executive, after deduction of any Excise Tax on the Payments and
all income taxes and Excise Tax upon such Company payment, shall be equal to the
Payments. The determination of whether any Payments are subject to the Excise
Tax shall be based on the opinion of tax counsel selected by the Company and
reasonably acceptable to the Executive, whose fees and expenses shall be paid by
the Company.  For purposes of determining the amount of the Gross-Up Payment,
the Executive shall be deemed to pay federal, state and local income taxes at
the highest marginal rate of income taxation applicable to any individual
residing in the jurisdiction in which the Executive resides in the calendar year
in which the Gross-Up Payment is to be made.  In the event that the Excise Tax
is subsequently determined to be less than the amount taken into account
hereunder at the time of termination of the Executive's employment, the
Executive shall repay to the Company, at the time that the amount of such
reduction in Excise Tax is finally determined, the portion of the Gross-Up
Payment attributable to such reduction (plus that portion of the Gross-Up
Payment attributable to the Excise Tax and federal, state and local income tax
imposed on the Gross-Up Payment attributable to the Excise Tax and federal,
state and local income tax imposed on the Gross-Up Payment being repaid by the
Executive to the extent that such repayment results in a reduction in Excise Tax
and/or a federal, state or local income tax deduction) plus interest on the
amount of such repayment at the rate provided in Section 1274(b)(2)(B) of the
Code.  In the event that the Excise Tax is determined to exceed the amount taken
into account hereunder at the time of the termination of the Executive's
employment (including by reason of any payment the existence or amount of which
cannot be determined at the time of the Gross-Up Payment), the Company shall
make an additional Gross-Up Payment in respect of such excess (plus any
interest, penalties or additions payable by the Executive with respect to such
excess) at the time that the amount of such excess is finally determined.  The
Executive and the Company shall each reasonably cooperate with the other in
connection with any administrative or judicial 

                                      -12-

proceedings concerning the existence or amount of liability for Excise Tax with
respect to the Payments.
