                                LICENSE AGREEMENT

        THIS LICENSE AGREEMENT is made to be effective as of this 31st day of
August 2001 (the "Effective Date"), by and between SMARTIRE SYSTEMS INC., a
British Columbia corporation having its principal place of business at 13151
Vanier Place, Suite 150, Richmond, British Columbia, Canada V6V 2J1
("SmarTire"), and TRW INC., a corporation existing under the laws of the State
of Ohio, United States of America, acting for and on behalf of its Automotive
Electronics operation in the U.S., having a place of business at 24175 Research
Drive, Farmington Hills, Michigan, United States of America 48335-2642 ("TRW").

        WHEREAS, the parties have been cooperating in the development and
marketing of tire pressure monitoring systems pursuant to certain agreements
including a License Agreement, Technical Cooperation Agreement, and Supply
Agreement, all dated as of 20 April 1998 and amended (in the case of the License
Agreement and Technical Cooperation Agreement) via an Assignment and Amending
Agreement dated as of 13 December 2000, and a Mutual Secrecy Agreement dated as
of 6 January 1998 and amended in a First Amendment dated 18 February 1998;

        WHEREAS, through their respective activities in the area of tire
pressure monitoring systems, the parties now each own respective intellectual
property that is useful in connection with the design and manufacture of tire
pressure monitoring systems;

        WHEREAS, pursuant to a Termination Agreement of even date herewith, the
parties are terminating the existing cooperation and the agreements associated
therewith; and,

        WHEREAS, each party wishes to receive from the other party a license to
use such other party's intellectual property in the manufacture and sale of tire
pressure monitoring systems subsequent to the termination of the existing
cooperation;

        NOW, THEREFORE, in view of the foregoing premises and in consideration
of the mutual promises and covenants contained in this and the related
termination agreements, SmarTire and TRW agree as follows:

                                    Article 1
                                   Definitions

        The following words and phrases will have the meanings set forth below
where used herein with initial capital letters:

        1.1    Affiliate: Any corporation, partnership, or other business entity

voting stock or otherwise has more than fifty percent (50%) of the right to
control the entity.

        1.2    Licensed Products: Tire pressure monitoring systems and
components of such systems, including but not limited to tire pressure

        1.3    TRW Patents: All utility patents, design patents, utility models,
or applications for patents or utility models that (a) were originally filed
before the Effective Date or, although filed after the Effective Date, are
directed to inventions made before the Effective Date, and (b) have a claim
covering Licensed Products, components of Licensed Products, or methods of
making or using same, and (c) the TRW Automotive Electronics operation in the
U.S. has the right, whether by reason of ownership of the patent, utility model
or application or otherwise, to grant licenses to SmarTire on the Effective
Date. The term "TRW Patents" does not include any patents filed on inventions
developed and owned by divisions of TRW Inc. other than its Automotive
Electronics operation, but does include patents filed on inventions developed
and owned by Affiliates of TRW, or divisions of Affiliates of TRW, that are
managed and operated as part of TRW's Automotive Electronics operation. The term
"TRW Patents" includes, without limitation, the publicly known patents and
pending patent applications listed on Attachment 1 hereto.

        1.4    Other Definitions and Meanings: For purposes of this Agreement,
(a) the term "person" includes any natural person, firm, association,
partnership, corporation, or other entity and (b) the words "hereof", "herein",
"hereby" and other words of similar import refer to this Agreement as a whole.

        2.1    Grant: TRW hereby grants to SmarTire the perpetual, royalty-free,
non-exclusive, worldwide right under the TRW Patents to make, have made, import,
use, and sell Licensed Products.

        2.2    Sublicenses: SmarTire may grant to its Affiliates sublicenses
under the rights granted herein, but may not otherwise grant sublicenses under
the rights granted herein. However, the foregoing notwithstanding, SmarTire may
grant limited sublicenses to vendors cooperating in the supply of products to
customers for a tire pressure monitoring system of those customers, if in each
case (a) SmarTire is supplying other material products for use in the same
system for the same customer, and (b) the sublicensed technology is necessary,
as opposed to merely useful or convenient, in order for such products of the
cooperating vendor to interface with such products of SmarTire. Any such
sublicense will be restricted to such necessary technology, only, and to such
system and such customer or vendor, only. For purposes of this paragraph, the
"vendor" and the "customer" may be the same company.

        2.3    Patents owned by TRW Affiliates: Certain of the TRW Patents are
owned by an Affiliate of TRW. Specifically, the Automotive Electronics division
of TRW France SA has filed patent applications on inventions covering Licensed
Products. TRW will cause TRW France SA to endorse and confirm the licenses
granted to SmarTire hereunder.

patent.
