nature whatsoever, whether direct, indirect, known or unknown, accrued,
inchoate, contingent, potential or otherwise in statutory or common law, or in
equity.

2.      CLAIMS NOT RELEASED. Nothing in this Release constitutes, and no party
shall claim that this Release constitutes, a release, or otherwise impairs the
enforceability, of any or all of the following:

        (a) The rights and obligations of the parties under the Termination
Agreement entered into by the parties on the date hereof, or the other documents
referenced therein, or any Claim for breach of or default under any of the
provisions of such documents; or

        (b) TRW's rights as a shareholder of SmarTire; or

        (c) Claims for breach of those provisions of the Secrecy Agreement that
survive termination thereof, but only for breaches of the surviving provisions
that occur after the date of this Release and that are not otherwise permitted
by the Termination Agreement or the documents referenced therein.

3.      INDEMNIFICATION AND EXCULPATION OF TRW APPOINTED SMARTIRE DIRECTORS.
SmarTire covenants to maintain in effect for a period of at least six (6) years
after the Effective Date policies of directors' and officers' liability
insurance equivalent in all material respects to those maintained by or on
behalf of SmarTire on the date hereof (and having coverage and containing terms
and conditions which in the aggregate are not less advantageous to the persons
currently covered by such policies as insured) with respect to Claims arising
from any actual or alleged


                                       2
<PAGE>

wrongful act or omission by any TRW employees who served as a SmarTire director
prior to the Effective Date. If at any time during the six (6) years after the
Effective Date SmarTire desires to change any of the material terms of its
directors' and officers' liability insurance or the carrier(s) of such
insurance, SmarTire will give to TRW and each TRW employee who served as a
SmarTire director advance written notice sufficient to permit them to protect
their interest in such policies of insurance, but not less than fourteen (14)
days notice. Notwithstanding any other provision hereof, the provisions of this
Section are (i) intended to be for the benefit of, and will be enforceable by,
TRW, each TRW employee who served as a director of SmarTire, their heirs and
representatives, and (ii) are in addition to, and not in substitution for, any
other rights to indemnification or contribution that any such person may have by
contract or otherwise. SmarTire represents and warrants that a true, correct and
complete copy of SmarTire's existing officers' and directors' liability
insurance policies have been, or will be within ten (10) days after the date on
which SmarTire receives copies of such policies from its insurers, provided to
TRW.

4.      COVENANT NOT TO SUE. Each of SmarTire and TRW hereby covenants to and
agrees with the other that it will not commence or prosecute any action or suit
in law or in equity against the other involving any claim (including without
limitation any of the Claims) that now exists or may hereafter exist arising
from, or in any way relating to, any of the matters released by it in Section 1
of this Release. Upon the breach of this covenant by a party, the other party
hereto shall be entitled to recover from the breaching party, in addition to any
other damages or remedy, all liability and actual attorneys' fees and costs
incurred by the other party in the defense or settlement of such action or suit.

5.      REPRESENTATIONS AND WARRANTIES.

        (a) Each of SmarTire and TRW warrants and represents to the other that
no person or entity not bound legally by this Release has any right to assert
any of the Claims released by it in Section 1, above, by or through that party,
and that it has not assigned or otherwise transferred to any person or entity
not bound legally by this Release any of the Claims released by it in Section 1
or any interest in, or right to, any of such Claims. Each of SmarTire and TRW
hereby agrees to indemnify, defend and hold the other harmless from any and all
liability and expenses, including without limitation actual attorneys' fees,
arising from, or in any way relating to, any claim asserted by any person or
entity contending not to be bound legally by this Release and based upon such
person's or entity's claiming to have any right to assert any of such Claims.

        (b) Each of the parties warrants and represents that no promises or
inducements have been offered except as herein stated, and this Release is
executed without reliance upon any statement or representation by the other
party concerning the nature or extent of any claims, damages or legal liability.
By execution of this Release, the parties hereto agree to be deemed joint
authors and drafters of this Release.
