as of December 22, 2000, by and between Pollution Research and Control Corp., a
California corporation ("PRCC") and Steven Sion ("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

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 100,000 shares of Common
Stock (the "Option Shares").

     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

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 her interests in
connection with the transaction;

<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

          business purposes related to, or in the furtherance of, the goals and
          objectives of the Company and/or the provision of the Services

          subject to Rule 144 of the General Rules and Regulations promulgated

          event, the Company shall be obligated to prepare and file a

     terminate the Consulting Period upon written notice. Termination shall not
     occur for a period of one year except for cause. Cause shall be defined as
     the Consultant failing to perform the duties outlined in the Agreement in
     good faith and failing to properly service the Company's needs as
     reasonably expected under the implied "good faith" provisions herein.
     Thirty days' written notice (the "Notice of Intended Termination") shall be
     given to the Consultant with the opportunity to cure within 30 days. Such
     Notice of Intended Termination shall state specifically the facts and
     circumstances claimed as the basis for said termination of the Consulting
     Agreement. Such notice must be approved by a majority of the Board of
     Directors of the Company.

          b. Not less than 15 days after receipt of the Notice of Intended

     (the "Board"). The Board shall present to Consultant its reasons for the
     termination, including the specific actions, inactions, omissions, or other
     facts relied upon by the Board in making its determination. Consultant
     shall have the right to rebut any evidence or allegations of wrongdoing and
     shall have the right to be represented by counsel of Consultant's choice at
     such hearing. After such hearing, should the Board determine that this
     Agreement shall be terminated for Cause, it shall issue a written final
     notice of termination (the "Final Notice of Termination") to Consultant,
     approved by a majority of the Board of Directors, setting forth in detail
     the specific facts, conclusions, and findings of the Board in determining
     that cause exists for their termination of this Agreement. The Final Notice

perform this Agreement in the same manner, and to the same extent, that the

any successor to its business and/or assets that executes and delivers the
Agreement provided for in this Section 10, or that otherwise becomes bound by

for whatever reason, the provisions hereof shall survive such termination,

agreements entered into and to be performed entirely therein. Any suit, action,
or proceeding with respect to this Agreement, shall be brought exclusively in
the state courts of the State of California, or in the federal courts of the

further agree that they shall both use good faith efforts in their performance
of the covenants, conditions and obligations stated herein and any failure to do
so shall be a material breach of this Agreement.

     16. Severability. If any term, covenant, or provision, or any part thereof,
is found by any court of competent jurisdiction to be invalid, illegal, or
unenforceable in any respect, the same shall not affect the remainder of such
term, covenant, provision, any other terms, covenants or provisions, or any
subsequent application of such term, covenant, or provision, or portion thereof.
In lieu of any such invalid, illegal, or unenforceable provision, the parties
hereto intend that there shall be added, as part of this Agreement, a term,
covenant, or provision, as similar in terms to such invalid, illegal, or
unenforceable term, covenant, or provision, or part thereof, as may be possible,
and such similar term, covenant, or provision shall be valid, legal, and
enforceable.

     IN WITNESS HEREOF, the parties hereto have duly executed and delivered this
Agreement as of the day and year first written above.
