                                OPTION AGREEMENT


     This Option Agreement (the  "Agreement") is made and entered into effective
as of May 18, 1997 by and  between  Pollution  Research  and  Control  Corp.,  a
California corporation ("PRCC") and Jorel Management Corp. ("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 50,000 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 50,000 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 $.75 (the ""Option Price"),  and for purposes of record, the bid price of the

     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


                                      E-29

<PAGE>


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;

          (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


                                      E-30

          OR OTHERWISE  TRANSFERRED  UNLESS SO REGISTERED OR QUALIFIED
          OR UNLESS AN EXEMPTION EXISTS,  THE 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
Common  stock by reason  of any  reclassification,  recapitalization,  split-up,
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.
