                                OPTION AGREEMENT

     This Option Agreement (the "Agreement") is made and entered into effective
as of February 26, 1999 by and between Pollution Research and Control Corp., a
California corporation ("PRCC") and Anthony Reneau ("Optionee").

     WHEREAS, Optionee has been providing valuable services as recognized by the
Company's Board of Directors to PRCC and PRCC is desirous of having Optionee
continue to provide such services to it; and

     WHEREAS, PRCC is willing to grant Optionee an option to purchase up to an
aggregate of 25,000 shares of the no par value common stock of PRCC (the "Common
Stock") under the terms and conditions set forth below.

     NOW, THEREFORE, the parties agree as follows:

     1. Grant of Option. PRCC hereby grants to Optionee, as a matter of separate
agreement and not in lieu of other compensation for services, the right and
option (the "Option") to purchase on the terms and conditions set forth in this
Agreement all or any part of up to an aggregate of 25,000 shares of Common Stock
(the "Option Shares"), for continuous, uninterrupted, employment service to PRCC
or by specific acknowledgement of exception by the Company's Board of Directors.

     2. Option Price. At any time when shares of Common Stock are to be
purchased pursuant to the Option, the purchase price for each Option share shall
be $1.00 (the ""Option Price"), and for purposes of record, the bid price of the
Company's stock on this date was $1.38.

     3. Option Period. The option period shall commence on November 1, 1999 (the
"Date of Grant") and shall terminate February 25, 2002.

     4. Exercise of Option. The Option may be exercised in whole or in part at
any time after the date hereof by delivering to the Chief Financial Officer of
PRCC (a) a Notice and Agreement of Exercise of Option, substantially in the form
attached hereto as Exhibit "A," specifying the number of Option Shares with
respect to which the Option is exercised, and (b) full payment of the Option
Price for such Shares.

     5. Securities Laws Requirements. The Option Shares have not been registered
under the Securities Act of 1933, as amended (the "Act"), and no Shares may be
sold, offered for sale, transferred, pledged, hypothecated or otherwise disposed
of except in compliance with the Act and any other applicable federal and state
securities laws. Additionally, the Option and the Option Shares have not been
qualified under the California Securities Law of 1968, as amended (the
"California Law"). PRCC has no obligation to register the Option shares under
the Act or qualify the Option Shares under the California Law. Optionee
acknowledges that he is aware that Rule 144 of the General Rules and Regulations
under the Act ("Rule 144") affords a limited exemption from registration for the
public resale of registered securities and under the terms of Rule 144 as
currently in effect, the Shares received by Optionee may be sold to the public
without registration only after a period of two (2) years has elapsed from the
exercise date of the Option and then only in compliance with all other
requirements of Rule 144 and the Act. Optionee hereby acknowledges, represents,
warrants and agrees as follows:

          (a) That the Option and the Option Shares are not registered under the
Act or qualified under the California Law, and the Option Shares shall be,
acquired solely for the account of Optionee for investment purposes only and
with no view to their resale or other distribution of any kind;

          (b) Neither the Option nor any Option Share shall be sold or otherwise
distributed in violation of the Act, the California Law or any other applicable
federal or state securities law;

          (c) His overall commitment to investments that are not readily
marketable is not disproportionate to his net worth, and his investment in PRCC
will not cause such overall commitment to become excessive;

          (d) He has the financial ability to bear the economic risk of his
investment, has adequate means of providing for his current needs and personal
contingencies, and has no need for liquidity in his investment in PRCC;

          (e) He either: (i) has a preexisting personal or business relationship
with PRCC or its officers, directors or controlling persons, or (ii) has
evaluated the business of PRCC and the high risks of investing in PRCC, the
competitive nature of the business in which PRCC is engaged, and has the
business or financial experience or has business or financial advisors who are
unaffiliated with, and not compensated by, PRCC and protect his interests in
connection with the transaction;

                                       3
<PAGE>

          (f) He has been given the opportunity to review all books, records and
documents of PRCC and to ask questions and receive answers from PRCC concerning
PRCC's business, to obtain additional information necessary to verify the
accuracy of the information he has desired in order to evaluate his investment,
and to consult with such attorneys, accountants and other advisors as he has
desired;

          (g) His residence set forth below is his true and correct residence,
and he has no present intention of becoming a resident or domiciliary of any
other state of jurisdiction;

          (h) In making the decision to accept the Option and/or purchase the
Option Shares, he has relied solely upon independent investigations made by or
on behalf of him;

          (i) No federal or state agency has made any finding or determination
as to the fairness of an investment in PRCC; and

          (j) He understands that all the representations and warranties made by
him herein, and all information furnished by him to PRCC, is true, correct and
complete in all respects.

     6. Optionee hereby acknowledges that he understands the meaning and legal
consequences of the representations, warranties and covenants contained herein
and that PRCC has relied on the representations made by Optionee in paragraph 5
hereof in granting this Option, and Optionee agrees to indemnify and hold
harmless PRCC and its officers, directors, controlling persons, attorneys,
agents and employees from and against any and all loss, damage or liability,
together with all costs and expenses (including attorneys' fees and
disbursements) which any of them may incur by reason of any breach and any
representation, warranty, covenant or agreement contained herein. All
representations, warranties, covenants and agreements, and the indemnification
contained herein shall survive the grant of the Option and the issuance of the
Option Shares by PRCC.

     7. Legend of Certificates. All Option Shares issued pursuant to this
Agreement shall be subject to the provisions of this Agreement and the
certificates representing such Option Shares shall bear the following legend or
language substantially equivalent thereto:

     AVAILABILITY OF WHICH IS TO BE ESTABLISHED TO THE SATISFACTION OF THE
     COMPANY."

     8. Transferability of Option. The Option shall not be transferable except
by the laws of descent and distribution and any attempt to do so shall void the
Option.

     9. Adjustment. The Option Price and the number and kind of Option Shares
shall be subject to corresponding adjustment in the event of any change in the

combination, exchange of shares, readjustment or stock dividend, in like manner
as if such Option Shares had been issued and outstanding, fully paid and
non-assessable at the time of such occurrence.

     10. Privilege of Ownership. Optionee shall not have any of the rights of a
shareholder with respect to the shares covered by the Option except to the
extent that one or more certificates for such Shares shall be delivered to his
upon one (1) or more exercises of the Option.

     11. Notices. Any notices required or permitted to be given under this
Agreement shall be in writing and they shall be deemed to have been given upon

PART A:  COMMON STOCK

Section 1.    Voting Rights.
              --------------

a.  One Vote Per Share.  The holders of shares of Common Stock shall be entitled
    ------------------
to one vote for each share so held with respect to all matters voted on by the
holders of shares of Common Stock of the Corporation.

b.  Two-Thirds Consent.  Consent of the holders of at least two-thirds (2/3)
    ------------------
of the outstanding shares of Common Stock shall be required for (i) any action
which results in a consolidation or merger which would be treated as a
liquidation, dissolution or winding up of the Corporation under Section 2 of
this Part A of this Article III, or which results in the liquidation, sale or
assignment of all or substantially all of the assets of the Corporation; (ii)
any amendment to these Articles of Incorporation; or (iii) any amendment by the
shareholders of the Corporation of the Bylaws of the Corporation (the Board of
Directors of the Corporation, as provided in Section 3 of Article VII, shall
have the authority to amend the Bylaws of the Corporation without the consent of
the shareholders of the Corporation).

Section 2.    Liquidation Rights.  Subject to preferences applicable to any

outstanding shares of Preferred Stock, all distributions made or funds paid to
the holders of Common Stock upon the occurrence of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Corporation shall
be made on the basis of the number of shares of Common Stock held by each of
them.  A consolidation or merger of the Corporation with or into another
corporation or entity shall be regarded as a liquidation, dissolution or winding
up of the Corporation within the meaning of this Section 2 unless such
consolidation or merger is not intended to effect a change in the ownership or
control of the Corporation or of its assets and is not intended to alter
materially the business or assets of the Corporation, including, by way of
example and without limiting the generality of the foregoing:  (i) a
consolidation or merger which merely changes the identity, form or place of
organization of the Corporation, or which is between or among the Corporation
and any of its direct or indirect subsidiaries, or (ii) following such merger or
consolidation, shareholders of the Corporation immediately prior to such event
own not less than 51% of the voting power of such corporation immediately after
such merger or consolidation on a pro rata basis.

Section 3.    Dividends.  Dividends may be paid on the Common Stock as and when
              ---------
declared by the Board of Directors, subject to preferences applicable to any
outstanding shares of Preferred Stock.
<PAGE>

PART B:  PREFERRED STOCK

The Preferred Stock may be issued from time to time in one or more series. The
Board of Directors of the Corporation is hereby authorized, within the
limitations and restrictions stated in these Restated Articles of Incorporation,
to fix or alter the dividend rights, dividend rate, conversion rights, voting
rights, rights and terms of redemption (including sinking fund provisions), the
redemption price or prices, and the liquidation preferences of any wholly
unissued series of Preferred Stock, and the number of shares constituting any
such series and the designation thereof, or any of them, and to increase or
decrease the number of shares of any series subsequent to the issue of shares of
that series but not below the number of shares of such series then outstanding.
In case the number of shares of any series shall be so decreased, the shares
constituting such decrease shall resume the status which they had prior to the
adoption of the resolution originally fixing the number of shares of such
series.

                                  ARTICLE VII

1.   Director Liability.  A director of the Corporation shall not be personally
     ------------------
liable to the Corporation or its shareholders for monetary damages for breach of
fiduciary duty as a director. However, this provision does not eliminate or
limit the liability of a director for any of the following:

          (a) any breach of the director's duty of loyalty to the Corporation or
          its shareholders;

          (b) any acts or omissions not in good faith or that involve
          intentional misconduct or a knowing violation of law;

          (c) a violation of Section 551(1) of the Michigan Business Corporation
          Act, as amended (the "MBCA");

          (d) a transaction from which the director derived an improper personal
          benefit; or

          (e) an act or omission occurring before the date these Articles of
          Incorporation became effective in accordance with the pertinent
          provisions of the MBCA.

Any repeal, amendment or other modification of this Article VII shall not
adversely affect any right or protection of a director of the Corporation
existing at the time of such repeal, amendment or other modification.

If the MBCA is amended, after this Article becomes effective, to authorize
corporate action further eliminating or limiting personal liability of
directors, then the liability of directors shall be eliminated or limited to the
fullest extent permitted by the MBCA as so amended.

2.   Control Share Acquisitions.  Chapter 7B of the MBCA, known as the "Stacey,
     --------------------------
Bennett, and Randall shareholder equity act," does not apply to control share
acquisitions of shares of the Corporation.

3.   Amendment of Bylaws.  In furtherance and not in limitation of the powers
     -------------------
conferred by statute, the Board of Directors of the Corporation is expressly
authorized to make, alter or repeal the Bylaws of the Corporation.

PART A:  COMMON STOCK

     Section 1.  Voting Rights.
     ---------   -------------

     a.  One Vote Per Share.  The holders of shares of Common Stock shall be
         ------------------
entitled to one vote for each share so held with respect to all matters voted on
by the holders of shares of Common Stock of the Corporation.

     b.  Two-Thirds Consent.  Consent of the holders of at least two-thirds
         ------------------
(2/3) of the outstanding shares of Common Stock shall be required for (i) any
action which results in a consolidation or merger which would be treated as a
liquidation, dissolution or winding up of the Corporation under Section 2 of
this Part A of this Article III, or which results in the liquidation, sale or
assignment of all or substantially all of the assets of the Corporation; (ii)
any amendment to these Articles of Incorporation; or (iii) any amendment by the
shareholders of the Corporation of the Bylaws of the Corporation (the Board of
Directors of the Corporation, as provided in Section 3 of Article VII, shall
have the authority to amend the Bylaws of the Corporation without the consent of
the shareholders of the Corporation).

     Section 2.    Liquidation Rights.  Subject to preferences applicable to any
     ---------     ------------------
outstanding shares of Preferred Stock, all distributions made or funds paid to
the holders of Common Stock upon the occurrence of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Corporation shall
be made on the basis of the number of shares of Common Stock held by each of
them.  A consolidation or merger of the Corporation with or into another
corporation or entity shall be regarded as a liquidation, dissolution or winding
up of the Corporation within the meaning of this Section 2 unless such
consolidation or merger is not intended to effect a change in the ownership or
control of the Corporation or of its assets and is not intended to alter
materially the business or assets of the Corporation, including, by way of
example and without limiting the generally of the foregoing:  (i) a
consolidation or merger which merely changes the identity, form or place of
organization of the Corporation, or which is between or among the Corporation
and any of its direct or indirect subsidiaries, or (ii) following such merger or
consolidation, shareholders of the Corporation immediately prior to such event
own not less than 51% of the voting power of such corporation immediately after
such merger or consolidation on a pro rata basis.

     Section 3.    Dividends.  Dividends may be paid on the Common Stock as and
     ---------     ---------
when declared by the Board of Directors, subject to preferences applicable to
any outstanding shares of Preferred Stock.

PART B:  PREFERRED STOCK

     The Preferred Stock may be issued from time to time in one or more series.
The Board of Directors of the Corporation is hereby authorized, within the
limitations and restrictions stated in these Restated Articles of Incorporation,
to fix or alter the dividend rights, dividend rate, conversion rights, voting
rights, rights and terms of redemption (including sinking fund provisions), the
<PAGE>

redemption price or prices, and the liquidation preferences of any wholly
unissued series of Preferred Stock, and the number of shares constituting any
such series and the designation thereof, or any of them, and to increase or
decrease the number of shares of any series subsequent to the issue of shares of
that series but not below the number of shares of such series then outstanding.
In case the number of shares of any series shall be so decreased, the shares
constituting such decrease shall resume the status which they had prior to the
adoption of the resolution originally fixing the number of shares of such
series.
