is made and entered into effective as of  June 1, 1996 by and between Pollution
Research and Control Corp., a California corporation ("PRCC") and Ron

                                        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 300,000  shares of the no

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  300,000  shares of Common Stock (the "Option Shares"), for
continuous, uninterrupted, employment service to PRCC or by specific

when shares of Common Stock are to be purchased pursuant to the Option, the
purchase price for each Option share shall be $1.10 (the "Option Price"), and

                                        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,





                                       3

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;

                                        (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
