         SECURITIES AND EXCHANGE'S POSITION REGARDING INDEMNIFICATION

The Company's Articles provide for indemnification of officers and directors.

Insofar as indemnification for liabilities arising under the Act might be

provisions described above, the Company has been informed that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in that Act and is therefore unenforceable.

Section 128 of the Company Act (British Columbia) if: (a) the person acted
honestly and in good faith with a view to the best interests of the corporation
of which the person is or was a director or officer; and (b) in the case of a
criminal or administrative action or proceeding, the person had reasonable

ITEM 9   UNDERTAKINGS

The undersigned Registrant hereby undertakes:

         (a)      For purposes of determining any liability under the Securities
                  Act, each filing of the Registrant's annual report pursuant to
                  Section 13(a) or 15(d) of the Exchange Act, that is
                  incorporated by reference in the registration statement shall
                  be deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (b)      Insofar as indemnification for liabilities arising under the
                  Securities Act may be permitted to directors, officers and
                  controlling persons of the Registrant pursuant to the
                  foregoing provisions, or otherwise, the Registrant has been
                  advised that in the opinion of the Securities and Exchange
                  Commission such indemnification is against public policy as
                  expressed in the Securities Act and is, therefore,
                  unenforceable. In the event that a claim for indemnification
                  against such liabilities (other than the payment by the
                  Registrant of expenses incurred or paid by a director, officer
                  or controlling person of the Registrant in the successful
                  defense of any action, suit or proceeding) is asserted by such
                  director, officer or controlling person in connection with the
                  securities being registered, the Registrant will, unless in
                  the opinion of its counsel the matter has been settled by
                  controlling precedent, submit to a court of appropriate
                  jurisdiction the question whether such indemnification by it
                  is against public policy as expressed in the Securities Act
                  and will be governed by the final adjudication of such issue.

                                   SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Richmond, British Columbia, on June ____, 1999.

         (e)      "Option" means the irrevocable right and option to purchase,
                  from time to time, all, or any part of the Optioned Shares

                  2 hereof;

         (f)      "Optioned Shares" means the common shares of the Company,

         (g)      "Shares" means the common shares in the capital stock of the

compensation, subject to the terms and conditions hereinafter set forth, the
Option to purchase a total of 20,000 (TWENTY THOUSAND) Optioned Shares at the
price of $4.58 per Optioned Share, exercisable by the Purchaser in whole or in
part at any time before 5:00 o'clock p.m., Vancouver time, on the Expiry Date.

3. The Option shall, at 5:00 o'clock p.m., Vancouver time, on the Expiry Date,
forthwith expire and terminate and be of no further force or effect whatsoever.

4. In the event of the death of the Purchaser on or prior to the Expiry Date,

personal representative of the Purchaser at any time prior to 5:00 o'clock p.m.,

purchase price for the number of Optioned Shares specified in the Notice of
Exercise.

the Purchaser or his personal representative representing, in aggregate, the
number of Optioned Shares specified in the Notice of Exercise and in respect of
which the Company has received payment.

8. Nothing herein contained shall obligate the Purchaser to purchase any
Optioned Shares except those Optioned Shares in respect of which the Purchaser
shall have exercised his Option in the manner hereinbefore provided.

9. In the event of any subdivision, redivision or change of the Shares of the
Company at any time prior to the Expiry Date into a greater number of Shares,
the Company shall deliver at the time of any exercise thereafter of the Option
such additional number of Shares as would have resulted from such subdivision,
redivision or change if such exercise of the Option had been made prior to the
date of such subdivision, redivision or change.

10. In the event of any consolidation or change of the Shares of the Company at
any time prior to the Expiry Date into a lesser number of Shares, the number of
Shares deliverable by the Company on any exercise thereafter of the Option shall
be reduced to such number of Shares as would have resulted from such
consolidation or change if such exercise of the Option had been made prior to
the date of such consolidation or change.

11. The Purchaser shall have no rights whatsoever as a shareholder in respect of
any of the Optioned Shares (including any right to receive dividends or other
distribution therefrom or thereon) except in respect of which the Option has
been properly exercised in accordance with paragraphs 1 (d) and 7 hereof.

12. Time shall be of the essence of this Agreement.

13. This Agreement shall enure to the benefit of and be binding upon the
Company, its successors and assigns, and the Purchaser and his personal
representative to the extent provided in paragraph 4 hereof.

14. Subject to paragraph 4, this Agreement shall not be transferable or
assignable by the Purchaser or his personal representative and the Option may be
exercised only by the Purchaser or his personal representative.

15. The granting of the Option and the terms and conditions hereof shall be
subject to the approval of the Exchange and, if the Purchaser is an Insider, is
further subject to the approval of the shareholders of the Company prior to the
exercise of the Option.

16. If at any time during the continuance of this Agreement, the parties hereto
shall deem it necessary or expedient to make any alteration or addition to this
Agreement, they may do so by means of a written agreement between them which
shall be supplemental hereto and form part hereof and which shall be subject to
the approval of the Exchange and, if the Purchaser is an Insider, shall be
subject to the approval of the shareholders of the Company.

17. Wherever the plural or masculine are used throughout this Agreement, the
same shall be construed as meaning singular or feminine or neuter or the body
politic or corporate where the context of the parties thereto require.

18. This Agreement may be executed in several parts in the same form and such
parts as so executed shall together constitute one original agreement, and such
parts, if more than one, shall be read together and construed as if all the
signing parties hereto had executed one copy of this Agreement.

the approval of the Exchange and, if the option as originally constituted was
accepted for filing by the shareholders, that shareholder approval shall be

                  Manager shall give reasonable notice to SmarTire and the
                  Company prior to such disclosure and shall comply with any
                  applicable protective order or equivalent.

         (b)      The Manager shall take reasonable security precautions, at

                  confidential information, to keep confidential the
                  Confidential Information, as defined hereinabove.

         (c)      Confidential Information and Materials may be disclosed,

                  of any unauthorized use or disclosure of Confidential
                  Information or Materials, or any other breach of this
                  Agreement by the Manager, and shall co-operate with SmarTire
                  in every reasonable manner to aid SmarTire or the Company to

                  Materials and prevent all such further unauthorized use.

         (b)      The Manager shall return all originals, copies, reproductions
                  and summaries of or relating to the Confidential Information
                  at the request of SmarTire or, at the option of SmarTire,
                  certify destruction of the same.

         (c)      The parties hereto recognize that a breach by the Manager of
                  any of the provisions contained herein would result in damages
                  to SmarTire and that SmarTire could not be compensated
                  adequately for such damages by monetary award. Accordingly,
                  the Manager agrees that in the event of any such breach, in
                  addition to all other remedies available to SmarTire or the
                  Company at law or in equity, SmarTire and the Company shall be
                  entitled as a matter of right to apply to a court of competent
                  jurisdiction for such relief by way of restraining order,
                  injunction, decree or otherwise, as may be appropriate to
                  ensure compliance with the provisions of this Agreement.

4.       MISCELLANEOUS

         (a)      All Confidential Information and Materials are and shall
                  remain the property of the Company and SmarTire. By disclosing
                  information to the Manager, the Company and SmarTire do not

Dear Sirs:

                  Re:      Registration Statement on Form S-8


                  We are counsel to SmarTire Systems Inc. (the "Company"), a
British Columbia corporation, and have assisted in the preparation of the
Registration Statement of the Company on Form S-8 (the "Registration Statement")
covering 490,425 common shares (the "Shares") in the capital of the Company
granted or issuable pursuant certain Stock Option Agreements, a Management
Agreement and a Release and Settlement Agreement (each, an "Agreement").

                  We have examined originals or copies, certified or otherwise
identified to our satisfaction of the resolutions of the directors of the
Company with respect to the matters herein. We have also examined such statutes
and public and corporate records of the Company, and have considered such
questions of law as we have deemed relevant and necessary as a basis for the
opinion expressed herein. We have for the purposes of this opinion assumed the
genuineness of all signatures examined by us, the authenticity of all documents
and records submitted to us as originals and the conformity to all original
documents of all documents submitted to us as certified, photostatic or
facsimile copies.

                  Based upon and subject to the foregoing, and subject to the
qualifications hereinafter expressed, we are of the opinion that each Share to
be issued and sold by the Company pursuant to the Registration Statement will
be, when sold and paid for pursuant to the terms of the applicable Agreement,
validly issued, fully paid and non-assessable.

                  We are barristers and solicitors qualified to practice law in
the Province of British Columbia. Our opinion expressed above is limited to the
present laws of the Province of British Columbia and of the federal laws of
Canada applicable therein. This opinion is being furnished


<PAGE>   2
                                      -2-


solely in connection with the filing of the Registration Statement with the
Securities and Exchange Commission, and we hereby consent to the use of this
opinion as an exhibit to the Registration Statement. This opinion may not be
relied upon, used by or distributed to any person or entity for any other
purpose without our prior written consent.


                                          Yours truly,

                                          CLARK, WILSON
