presentment, protest, notice, notice of protest and notice of dishonor and

Lakewood, Colorado  80228

Dear Ms. Powell:

     I have  acted as counsel to Rub A Dub Soap,  Inc.,  a Colorado  corporation
(the  "Company"),  in connection with the  Registration  Statement on Form SB-1,
including  all pre- or  post-effective  amendments  thereto  (collectively,  the
"Registration Statement"),  which Registration Statement is being filed with the
U.S. Securities and Exchange Commission under Section 5 of the Securities Act of
1933 on or about  the date  hereof.  The  Registration  Statement  relates  to a
maximum of 800,000  shares (the  "Shares") of common stock,  $.001 par value per
share, being offered by the Company.

     In connection with this opinion,  I have examined the Company's Articles of
Incorporation;   the  Company's  Bylaws;  minutes  of  the  Company's  corporate
proceedings and unanimous written consents in lieu thereof, as made available to
me by the sole executive officer and director of the Company; executed copies of
such Registration Statement, and all exhibits thereto in the form filed with the
Commission;  and such matters of law deemed  necessary by me in order to deliver
the within opinion.

     In the course of my  examination,  I have  assumed the  genuineness  of all
signatures,  the  authenticity  of all  documents  submitted  to me as  original
documents, the conformity to original documents of all documents submitted to me
as certified or  photostatic  copies and the due  execution  and delivery of all
documents   where  due  execution  and  delivery  are  a  prerequisite   to  the
effectiveness  thereof.  As to  certain  factual  matters,  I have  relied  upon
information  furnished to me by the sole  executive  officer and director of the
Company.

     On the basis of the foregoing,  and solely in reliance thereon, I am of the
opinion that the Shares have been duly authorized and, upon effectiveness of the
Registration  Statement by order of the Securities  and Exchange  Commission (or
upon the  twentieth  day  following  the filing of an amendment  indicating  the
intention  to become  effective by operation of the terms of Section 8(a) of the
Securities Act of 1933) and the necessary state securities  authorities and upon

delivery of the Shares to  subscribers  against  payment  therefor in the manner
described in the Registration Statement, the Shares have been or will be validly
issued, fully-paid and nonassessable.

     I hereby  consent  to the  filing  of this  letter  as  Exhibit  (5) to the
Registration  Statement  and to  the  reference  to  Cudd  &  Associates  in the
Registration Statement.

                                                 Very truly yours,

that TRW is relying upon the truth and accuracy of those SmarTire
representations and warranties in entering into this transaction with SmarTire
and executing the agreements and related documents (collectively and heretofore
defined as the "Agreement") for that transaction:

    a. The execution, delivery and performance by SmarTire of this Agreement and
       the other documents contemplated hereby (with or without the giving of
       notice, the lapse of time, or both): (i) does not require the consent or
       approval of, prior filing with, or notice to, or other action by, any
       regulatory authority, stock exchange, or any other third party; (ii) will
       not conflict with any provision of SmarTire's articles of incorporation
       or bylaws; (iii) will not constitute a default under any law or judicial
       or regulatory order to which SmarTire is a party or by which SmarTire is
       bound; (iv) will not constitute a default under any contract, license or
       permit to which SmarTire is a party or by which SmarTire is bound; and
       (v) will not create any lien upon any of the assets of SmarTire, except
       the lien created under this Agreement and the General Security Agreement
       to secure SmarTire's payment of the amounts to be paid to TRW by
       SmarTire.

    b. SmarTire is a corporation duly organized, validly existing, and in good
       standing under the laws of British Columbia, and SmarTire has the
       corporate power and authority to carry on its business as it has been and

       or leases. SmarTire has the requisite power and authority to execute,
       deliver and perform its obligations under this Agreement according to its
       terms, and to consummate the transactions contemplated hereby. This
       Agreement has been duly executed and delivered by SmarTire, and
       constitutes the legal, valid and binding obligation of SmarTire,
       enforceable against SmarTire in accordance with its terms.

    c. [Intentionally left blank]

    d. Except as set forth on Exhibit 5 to this Agreement, SmarTire (i) has not
       formed, has not negotiated for the formation of, and has no current
       intention to form, any business combination or to enter into any other
       transaction with any third-party, the purpose of which is to develop
       and/or market tire monitoring systems; and (ii) has not marketed, sold or
       attempted to sell SmarTire products for use as original equipment in the

    f. No litigation is pending or threatened by any third party before any
       court of competent jurisdiction or regulatory authority seeking to
       restrain or prohibit or declare illegal, or seeking substantial damages
       in connection with, the transactions contemplated by this Agreement.

       or made and shall be in full force and effect. No consent obtained from
       any regulatory authority which is necessary to consummate the
       transactions contemplated hereby shall be conditioned or restricted in a
       manner (including requirements relating to the raising of additional
       capital or the disposition of assets) which in the reasonable judgment of
       TRW would so materially adversely impact the economic or business
       benefits of the transactions contemplated by this Agreement so as to
       render it inadvisable for TRW to proceed with the Closing.

    h. The SmarTire balance sheet and other financial information attached to,
       or by reference incorporated in, this Agreement is, and as of the Closing
       Date will be, accurate and true as at June 30, 2001, and presents fairly
       and accurately the financial information of SmarTire as of such date in
       accordance with generally accepted accounting principles applied on a
       consistent basis, and there has been no material adverse change to the
       financial condition or results of operations of SmarTire since such date
       except SmarTire's use of approximately US$500,000 per month for operating
       expenses.

4.2 The representations and warranties of SmarTire will survive the Closing.

4.3 TRW makes the following representations and warranties to SmarTire knowing
that SmarTire is relying upon the truth and accuracy of those TRW
representations and warranties in entering into this transaction with TRW and
executing the Agreement:

    a. The execution, delivery and performance by TRW of this Agreement and the
       other documents contemplated hereby (with or without the giving of

5.      RELEASE OF CLAIMS

5.1 SmarTire and TRW will execute and deliver to each other on the Closing Date
the Settlement and Release Agreement attached to, and by reference incorporated
in, this Agreement as Exhibit 6.

6.      CLOSING MATTERS

6.1 All public communication describing the April 1998 Agreements, the
relationship of the parties or this Agreement shall be subject to the prior
approval of the other party prior to dissemination. In considering such
approvals, each party will reasonably co-operate with the other in ensuring that
each party, as a publicly traded entity, can meet its regulatory compliance
requirements in a timely manner.

6.2 The parties will use reasonable commercial efforts to negotiate and achieve
a termination of all three party supply agreements involving TRW and SmarTire
and other parties. Any further relationship of TRW or SmarTire with such third
parties will be the sole responsibility of the party entering into such
relationship. With respect to the ASIS Purchase and Supply Contract between
SmarTire, TRW and SensoNor asa dated January 1, 2001 (the "SensoNor Agreement"),
TRW and SmarTire contemplate that such agreement will be superceded by
individual agreements between SensoNor and each of TRW and SmarTire, and that
each of TRW and SmarTire will pay to SensoNor equal amounts to settle all
alleged claims by SensoNor for payments related to the SensoNor Agreement. In
the event that either of TRW or SmarTire do not for any reason enter into a
separate agreement with SensoNor to replace the SensoNor Agreement or otherwise
terminate the SensoNor Agreement in a manner acceptable to both TRW and
SmarTire, the parties agree that the minimum volume purchase requirements under
the SensoNor Agreement shall be allocated between them on a fifty-fifty basis
(e.g., equal payment to SensoNor from each of TRW and SmarTire), and each party
covenants to hereafter satisfy fully its half of the minimum purchase
requirements or to pay its one-half amount to maintain the exclusivity rights
under the SensoNor Agreement.

6.3 Each party covenants that it will, in connection with the Closing and from
time to time subsequent to the Closing Date, execute such additional instruments
and take such actions as may be reasonably requested by the other party to
confirm or perfect or otherwise to carry out the intent and purpose of this
Agreement.

6.4 Each party hereby agrees that it shall indemnify, defend and hold harmless
the other party hereto from and against any loss, damage, liability, cost and
expense, including reasonable attorneys' fees, suffered or incurred by the other
party, as and when incurred, by reason of, or arising out of, any
misrepresentation, breach of warranty or breach or non-fulfillment of any
agreement of the party contained in this Agreement or in any document executed
and delivered in connection with this Agreement, or any claim by any
shareholder, creditor or affiliate of the party asserted against the other party
and arising out of, or in any way relating to, this Agreement or any transaction
between SmarTire and TRW, including without limitation the transactions and
activities under the April 1998 Agreements.

6.5 Any failure on the part of any party to comply with any of its obligations,
agreements or conditions hereunder may be waived by any other party to whom such
compliance is owed. No waiver of any provision of this Agreement shall be
deemed, or shall constitute a waiver of any other provision, whether or not
similar, nor shall any waiver constitute a continuing waiver.

6.6 This Agreement, together with the General Security Agreement, Secured
Promissory Note, Settlement and Release Agreement, Licenses and Guaranty,
constitute the entire understanding between the parties hereto with respect the
matters set forth herein, and, except to the extent expressly set forth in such
agreements, supersede all other agreements, oral or written, heretofore made
with respect to the subject matter hereof. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective heirs, legal
representatives, executors, administrators, successors and permitted assigns.

6.7 This Agreement shall be governed by, and construed in accordance with, the
laws of the State of Ohio. The provisions of this Agreement are severable and
the invalidity of one or more of the provisions herein shall not have any effect
upon the validity or enforceability of any other provision.

6.8 This Agreement may be executed in two or more counterparts (including
facsimile counterparts), each of which shall be deemed an original but all of
which together shall constitute one and the same instrument.

6.9 All notices. requests, demands and other communications hereunder shall be
in writing and shall be deemed to have been given if delivered by hand or if
mailed by United States registered or certified mail, return receipt requested,
first class postage prepaid, or sent by Federal Express or similar overnight

1.        PROMISE TO PAY

          FOR VALUE RECEIVED, the undersigned ("Maker") promises to pay to the
order of TRW Inc. ("TRW"), at 24175 Research Drive, Farmington Hills, Michigan

Maker's default under this Note. The interest hereunder is chargeable only on
amounts from time to time actually outstanding.

          The principal amount of this Note shall be paid in installment

be accompanied by a payment of all accrued interest as of the date of such
payment. The amounts and due dates of the principal payments are as follows:

               2001

This Note is given by Maker as part of the consideration payable by Maker under
that certain Termination Agreement of even date herewith made between Maker and
TRW and the documents executed by and between Maker and TRW under and in
connection with that Agreement. Payment by Maker of all amounts payable under
this Note and performance by Maker of all other obligations of Maker under this
Note and the Termination Agreement and documents referenced in, and executed in
connection with, that Agreement are secured by the collateral and other rights
granted

<PAGE>

to TRW by Maker under that certain General Security Agreement of even date
herewith that Maker executed and delivered to TRW with this Note, and under the
Guaranty executed by Maker's subsidiaries and delivered to TRW with this Note.

2.        COLLECTION RIGHTS

          Maker waives presentment, protest and notice of dishonor, and Maker
waives the right to all other notices or demands that might otherwise be
required by law. The holder may grant releases or compromises of this Note or
release any collateral therefor to any party who is liable to make payment on
this Note, without notice or consent of Maker, and without affecting the
liability of Maker.

3.        PREPAYMENT

          The Maker shall have the right to prepay the principal amount
outstanding in whole or in part without notice or penalty. Any partial
prepayment shall be applied first to payment of any accrued interest and then
against the principal amount outstanding and shall not extend or postpone the
due date of any subsequent installments or change such installments, unless the
holder hereof shall otherwise agree in writing.

4.        RIGHTS ON DEFAULT

          If any sum payable is not paid when due; if Maker, or other person
liable on this Note, shall become insolvent, become subject to an order for
relief under a bankruptcy law, either voluntary or involuntary, or make a
general assignment for the benefit of creditors; or if any proceeding for
enforcement of a judgment is commenced against Maker or any property of Maker;
or if Maker fails to perform any other obligation under this Note, the General
Security Agreement under which this Note is secured, or any of the agreements by
and between Maker and TRW pursuant to which this Note is given, all the amounts
owed, including accrued interest, shall become and be, at the option and
discretion of the holder, due and payable immediately without demand by, or
notice from, the holder. No delay on the part of holder in exercising any power
or right under this Note shall operate as a waiver of the power or right, nor
shall any single or partial exercise of any power or right preclude further
exercise of that power or right. Maker shall pay to holder all expenses incurred
by holder, including actual attorneys fees expended by holder, in enforcing any
of the provisions of this Note or the General Security Agreement.

5.        SECURITY AGREEMENT AND GUARANTY

          To secure payment of all obligations hereunder and the Maker's
performance of all obligations to TRW, the Maker has executed and delivered to
TRW the General Security Agreement. For any default in payment or the
performance of any other obligation of the Maker, the holder may, without
notice, declare this Note due forthwith and may realize on, or dispose of, the
collateral in any manner allowed by law. Payment of this Note and Maker's
performance of all obligations to TRW is further secured by the delivery to TRW
of that certain Guaranty executed by Maker's subsidiaries.

6.        MISCELLANEOUS

        Holder and the Maker, after consulting or having had the opportunity to
consult with counsel, knowingly, voluntarily and intentionally waive any right
either of them may have to a trial by jury in any litigation based upon or
arising out of this Note or any related instrument or agreement or any of the
transactions contemplated by this Note or any course of conduct, dealing,
statements, whether oral or written, or actions of either of them. Neither
Holder nor the Maker shall seek to consolidate, by counterclaims or otherwise,
any such action in which a jury trial has been waived with any other action in
which a jury trial cannot be or has not been waived. These provisions shall not
be deemed to have been modified in any respect or relinquished by either Holder
or the Maker, except by a written instrument executed by both of them.

          This Note has been made and delivered in the State of Michigan and
this Note shall be construed in accordance with the laws of the State of
Michigan. This Note and the provisions hereof are binding on the heirs,
executors, administrators, assigns, or successors of Maker.

4.      ATTACHMENT

4.1            The Debtor acknowledges that the security interests hereby

property will have, rights in the Collateral.

5.             REPRESENTATIONS AND WARRANTIES

5.1            The Debtor, represents and warrants that this Security Agreement

other matters and things have been done and performed so as to authorize and
make the execution and delivery of this Security Agreement, and the performance
of the Debtor's obligations hereunder, legal, valid and binding.

5.2            The Debtor represents and warrants that the Debtor lawfully owns
and possesses all presently held Collateral and has good title thereto, free
from all security interests, charges, encumbrances, liens and claims, save only
the charges or security interests, if any, shown in Schedule "A" hereto and
those consented to in writing by the Secured Party, and the Debtor has good
right and lawful authority to grant a security interest in the Collateral as
provided by this Security Agreement.

5.3            Any and all credit or other information furnished to Secured
Party by Debtor in connection with the Debtor's obligation or financial
condition or the value or condition of the Collateral is true and correct, and
all such information hereafter furnished to Secured Party by Debtor will be true
and correct when furnished.

5.4            Except as disclosed in the financial statements furnished to
Secured Party by Debtor, and for trade payables arising in the ordinary course

5.5            Except as set forth on Schedule 5.5 attached hereto, there are no

investigations, contested claim, or governmental proceeding by or against Debtor
or any of its Subsidiaries except judgments and pending or threatened
litigation, investigations, contested claims and governmental proceedings which
are not, in the aggregate, material to Debtor's or any of its Subsidiaries'
business, operations, condition (financial or otherwise) or prospects. None of
the matters listed in Schedule 5.5 could reasonably be expected to have, either
individually or in the aggregate, a Material Adverse Effect (meaning, an effect

or obligation greater than $50,000.00 or result in any restriction on the manner
in which its business is currently operated) on Borrower or any of its
Subsidiaries.

contract, lease, or commitment which is material to the continued financial
success and well-being of Debtor or any of its Subsidiaries.

licenses, permits, patents, patent applications, copyrights, service marks,
trademarks, trademark applications, trade styles and trade names, governmental
approvals or other authorizations and other rights that are necessary for each
such entity to continue to conduct its business as heretofore conducted by it or
contemplated to be conducted by it.

5.8            The written information, exhibits and reports furnished by or on
behalf of Debtor or any of its Subsidiaries to Secured Party in connection with
the Termination Agreement, Secured Promissory Note and this Agreement, and all
certificates and documents delivered to Secured Party pursuant to the terms
thereof do not contain as of the date furnished any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements contained herein or therein, in light of the circumstances under
which they were made, not misleading.

5.9            The advances or other transfers of assets by Debtor to any
Subsidiary or other affiliate of Debtor is, and at the Closing will be,
accurately stated in the financial information provided to Secured Party with,
and as part of, this Agreement, and with respect to all such transfers: (i) they
are valid debt obligations of such Subsidiaries or other affiliates of Debtor
payable to Debtor without set off or reduction; and (ii) there has been no
default in the payment or performance of any of the Subsidiary's or other
affiliate's obligations under promissory notes or other debt instruments
evidencing those transfers.

6.             COVENANTS OF THE DEBTOR

               other matter relating to the Collateral or Debtor's financial
               condition, and render all assistance necessary for such
               inspection.

        (j)    do or cause to be done all things necessary to preserve in full

               applicable jurisdictions, and all rights, interests and assets
               necessary to the conduct of its business.

        (k)    Execute and deliver to the Secured Party upon request all
               financing statements, continuation statements and other documents

               discretion, in form satisfactory to the Secured Party, and do and
               perform all other acts as may be necessary, to perfect and
               maintain perfected the Secured Party's security interest in the

               under this Security Agreement. Debtor hereby irrevocably makes,
               constitutes and appoints the Secured Party (and any of the
               Secured Party's officers, employees or agents designated by the
               Secured Party) as Debtor's true and lawful attorney with power to
               sign the name of Debtor on any such documents.

        (l)    Debtor shall provide Secured Party, at the request of Secured

until payment in full of the Obligations.

pari passu with any security interest created by this Agreement, except (i)
trade obligations and normal accruals in the ordinary course of business not

        (m)    Other Matters. Subsequent to the Closing, Debtor will not
manipulate the timing of sales, the receipt of revenues or take any other action

perform all of its other obligations under this Agreement fully and punctually.

8.             PERFORMANCE OF OBLIGATIONS

Obligations without prejudice to any other rights and remedies of the Secured
Party hereunder, and any payments made and any costs, charges, expenses and
legal fees and disbursements (on a solicitor and his own client basis) incurred
in connection therewith will be payable by the Debtor to the Secured Party

in the ordinary course of its business and for the purposes of carrying on its
business.

10.            DEFAULT

10.1           The Debtor will be in "Default" under this Security Agreement,

        (a)    the Debtor fails to make any payment when due pursuant to the
               terms of any of the Obligations;

        (b)    the Debtor is in breach of any term, condition, obligation or
               covenant to the Secured Party set forth in this Agreement or any

        (d)    the Debtor becomes bankrupt or insolvent or makes an assignment
               for the benefit of, a proposal to, or an arrangement with its

               whether by the Debtor or any other person whereby the Debtor may
               be dissolved, wound-up, reorganized, or declared bankrupt or
               insolvent (for purposes of this Agreement the term "insolvent"
               means (i) that the liabilities of Debtor exceed its assets, or
               (ii); Debtor is unable to pay its obligations as they mature in
               the ordinary course of its business operations.)

        (e)    a receiver or receiver-manager is appointed in respect of the
               Debtor or any part of the Collateral;

        (f)    any execution, sequestration, extent, or any other process of any
               kind is levied or enforced upon or against the Collateral or any
               part thereof and remains unsatisfied for a period of 10 days;

        (g)    without the prior written consent of the Secured Party, the
               Debtor creates or permits to exist any charge, encumbrance or

               Collateral which ranks or could in any event rank in priority to
               or pari passu with any security interest or charge created by
               this Security Agreement with the exception of the security
               interests listed in Schedule "A" hereto;

<PAGE>
                                      -10-

        (h)    the holder of any other charge, encumbrance or lien on, or claim
               against, or security interest in, any of the Collateral does

               amalgamation, merger or other similar arrangement with any other

11.            ENFORCEMENT

11.1           Upon any Default under this Security Agreement, the Secured Party
may declare any or all of the Obligations not payable on demand to become
immediately due and payable and the security hereby constituted will immediately
become enforceable. To enforce and realize on the security constituted by this
Security Agreement the Secured Party may take any action permitted by law or in
equity, as it may deem expedient, and in particular without limiting the
generality of the foregoing, the Secured Party may do any of the following:

        (a)    appoint by instrument a receiver, receiver and manager or a
               receiver-manager (the person so appointed is hereinafter called
               the "Receiver") of the Collateral, with or without bond as the
               Secured Party may determine, and from time to time in its
               absolute discretion remove such Receiver and appoint another in
               its stead;

        (b)    enter upon any premises of the Debtor and take possession of the
               Collateral with power to exclude the Debtor, its agents and its
               servants therefrom, without becoming liable as a mortgagee in
               possession;

        (c)    preserve, protect and maintain the Collateral and make such
               replacements thereof and repairs and additions thereto as the
               Secured Party may deem advisable;

        (d)    sell, lease or otherwise dispose of all or any part of the
               Collateral, whether by public or private sale or lease or
               otherwise, in such manner, at such price as can be reasonably
               obtained therefor and on such terms as to credit and with such
               conditions of sale and stipulations as to title or conveyance or
               evidence of title or otherwise as to the Secured Party may seem
               reasonable, provided that if any sale is on credit the Debtor
               will not be entitled to be credited with the proceeds of any such
               sale, lease or other disposition until the moneys therefor are
               actually received; and

        (e)    exercise all of the rights and remedies of a secured party under
               the Act.

11.2           A Receiver appointed pursuant to this Security Agreement will be
the agent of the Debtor and not of the Secured Party and, to the extent
permitted by law or to such lesser extent permitted by its appointment, will
have all the powers of the Secured Party hereunder, and in addition will have
power to carry on the business of the Debtor and for such purpose from time to
time to borrow money either secured or unsecured, and if secured by a security
interest on any of the Collateral; such security interest may rank before or
pari passu with or behind any security

<PAGE>
                                      -11-

interest created by this Security Agreement, and if it does not so specify such
security interest will rank before the security interests created by this
Security Agreement.

11.3           All amounts realized from the disposition of Collateral pursuant
to this Security Agreement will be applied as the Secured Party, in its absolute
discretion, may direct as follows:

        (a)    in payment of all costs, charges and expenses (including legal
               fees and disbursements on a solicitor and his own client basis)
               incurred by the Secured Party in connection with or incidental
               to:

               (i)    the exercise by the Secured Party of all or any of the
                      powers granted to it pursuant to this Security Agreement;
                      and

               (ii)   the appointment of the Receiver and the exercise by the
                      Receiver of all or any of the powers granted to it
                      pursuant to this Security Agreement, including the
                      Receiver's reasonable remuneration and all outgoings
                      properly payable by the Receiver;

        (b)    in or toward payment to the Secured Party of all principal and
               other moneys (except interest) due in respect of the Obligations;
               and

        (c)    in or toward payment to the Secured Party of all interest
               remaining unpaid in respect of the Obligations.

Subject to applicable law and the claims, if any, of other creditors of the
Debtor, any surplus will be paid to the Debtor.

12.            DEFICIENCY

12.1           If the amounts realized from the disposition of the Collateral
are not sufficient to pay the Obligations in full the Debtor will immediately
pay to the Secured Party the amount of such deficiency.

13.            RIGHTS CUMULATIVE

13.1           All rights and remedies of the Secured Party set out in this
Security Agreement are cumulative and no right or remedy contained herein is
intended to be exclusive but each will be in addition to every other right or
remedy contained herein or in any existing or future security agreement or now
or hereafter existing at law, in equity or by statute, or pursuant to any other
agreement between the Debtor and the Secured Party that may be in effect from
time to time.

14.            LIABILITY OF SECURED PARTY

14.1           The Secured Party will not be responsible or liable for any debts
contracted by it, for damages to persons or property or for salaries or
non-fulfilment of contracts during any period when the Secured Party shall
manage the Collateral upon entry, as herein provided, nor will the Secured Party
be liable to account as mortgagee in possession or for anything except

<PAGE>
                                      -12-

actual receipts or be liable for any loss on realization or for any default or
omission for which a mortgagee in possession may be liable. The Secured Party
will not be bound to do, observe or perform or to see to the observance or
performance by the Debtor of any obligations or covenants imposed upon the
Debtor nor will the Secured Party, in the case of securities, instruments or
chattel paper, be obliged to preserve rights against other persons, nor will the
Secured Party be obliged to keep any of the Collateral identifiable. The Debtor
hereby waives any applicable provision of law permitted to be waived by it which
imposes higher or greater obligations upon the Secured Party than aforesaid.

15.            APPOINTMENT OF ATTORNEY

15.1           Debtor appoints the Secured Party, the Secured Party's designee
or the Receiver as its attorney-in-fact to endorse Debtor's name on any checks,
notes, acceptances, money orders, drafts or other forms of payment or security
that may come into the Secured Party or its designee's possession; to sign
Debtor's name on any document relating to any Accounts, on drafts against
Debtors, on schedules and assignments of Accounts, on notices of assignment and
other public records, on verifications of Accounts and on notices to Debtors; to
notify post office authorities to change the address for delivery of Debtor's
mail to an address designated by the Secured Party or its designee, to receive
and open all mail addressed to Debtor and to retain all mail relating to
Collateral and forward all other mail to Debtor; and to do all things necessary
to carry out or enforce this Agreement. Debtor ratifies and approves all acts of
the Secured Party or its designee as attorney-in-fact. The Secured Party, or its
designee, as attorney-in-fact, will not be liable for any acts or omissions, or
for any error of judgment or mistake of fact or law, except for bad faith. This
power, being coupled with an interest, is irrevocable until all Obligations have
been fully satisfied; provided that neither the Secured Party or its designee
will exercise this power until after a Default.

16.            ACCOUNTS

16.1           Notwithstanding any other provision of this Security Agreement,
the Secured Party may collect, realize, sell or otherwise deal with the Accounts
or any part thereof in such manner, upon such terms and conditions and at such
time or times, whether before or after default, as may seem to be advisable, and
without notice to the Debtor, except in the case of disposition after default
and then subject to the provisions of Part V of the Act. All moneys or other
forms of payment received by the Debtor in payment of any Account will be
received and held by the Debtor in trust for the Secured Party.

17.            APPROPRIATION OF PAYMENTS

17.1           Any and all payments made in respect of the Obligations from time
to time and moneys realized from any security interests held therefor (including
moneys collected in accordance with or realized on any enforcement of this
Security Agreement) may be applied to such part or parts of the Obligations as
the Secured Party may see fit, and the Secured Party may at all times and from
time to time change any appropriation as the Secured Party may see fit.

<PAGE>
                                      -13-

18.            LIABILITY TO ADVANCE

18.1           None of the preparation, execution, perfection and registration
of this Security Agreement or the advance of any moneys will bind the Secured
Party to make any advance or loan or further advance or loan, or renew any note
or extend any time for payment of any indebtedness or liability of the Debtor to
the Secured Party.

19.            WAIVER

19.1           The Secured Party may from time to time and at any time waive in
whole or in part any right, benefit or default under any clause of this Security
Agreement but any such waiver of any right, benefit or default on any occasion
will be deemed not to be a waiver of any such right, benefit or default
thereafter, or of any other right, benefit or default, as the case may be.

20.            NOTICE

20.1           Notice may be given to either party by sending it through the
post in prepaid mail or delivered to the party for whom it is intended, at the
principal address of such party provided herein or at such other address as may
be given in writing by such party to the other, and any notice if posted will be
deemed to have been given at the expiration of three business days after posting
and if delivered, on delivery.

21.            EXTENSIONS

21.1           The Secured Party may grant extensions of time and other
indulgences, take and give up security, accept compositions, compound,
compromise, settle, grant releases and discharges, refrain from perfecting or
maintaining perfection of security interests, and otherwise deal with the
Debtor, account debtors of the Debtor, sureties and others and with the
Collateral and other security interests as the Secured Party may see fit without
prejudice to the liability of the Debtor or the Secured Party's right to hold
and realize on the security constituted by this Security Agreement.

22.            NO MERGER

22.1           This Security Agreement will not operate so as to create any
merger or discharge of any of the Obligations, or any assignment, transfer,
guarantee, lien, contract, promissory note, bill of exchange or security
interest of any form held or which may hereafter be held by the Secured Party
from the Debtor or from any other person whomsoever. The taking of a judgment
with respect to any of the Obligations will not operate as a merger of any of
the covenants contained in this Security Agreement.

23.            ASSIGNMENT

23.1           The Secured Party may, without further notice to the Debtor, at
any time assign, transfer or grant a security interest in this Security
Agreement and the security interests granted hereby. The Debtor expressly agrees
that the assignee, transferee or secured party, as the case may be, will have
all of the Secured Party's rights and remedies under this Security Agreement

<PAGE>
                                      -14-

and the Debtor will not assert any defence, counterclaim, right of set-off or
otherwise any claim which it now has or hereafter acquires against the Secured
Party in any action commenced by such assignee, transferee or secured party, as
the case may be, and will pay the Obligations to the assignee, transferee or
secured party, as the case may be, as the Obligations become due.

24.            SATISFACTION AND DISCHARGE

24.1           Any partial payment or satisfaction of the Obligations, or any
ceasing by the Debtor to be indebted to the Secured Party, will be deemed not to
be a redemption or discharge of this Security Agreement. The Debtor will be
entitled to a release and discharge of this Security Agreement upon full payment

                      (C)    any rights a Person has in such sold, leased, or

               it is entitled to receive, hold, and dispose of the document and
               the Goods it covers, and (c) any receipt covering Goods stored
               under a statute requiring a bond against withdrawal or a license
               for the issuance of receipts in the nature of warehouse receipts

                                    GUARANTY

         THIS GUARANTY ("Guaranty") is made as of August 31, 2001, by SMARTIRE
USA, Inc., a Delaware corporation, SMARTIRE TECHNOLOGIES, INC., a company
incorporated in the Province of British Columbia and SMARTIRE (EUROPE) LIMITED,
a UK company (collectively "Guarantor"), in favor of TRW INC., an Ohio
corporation, of 24175 Research Drive, Farmington Hills, Michigan 48335-2642
("TRW") to induce TRW to extend credit or some other benefit (collectively,
"Indebtedness"), to SMARTIRE SYSTEMS INC., a company incorporated in the
Province of British Columbia, of 150-13151 Vanier Place, Richmond, British
Columbia, U6U251 and its successors ("SmarTire"), and because Guarantor has
determined that executing and delivering this Guaranty is in Guarantor's
interest and to Guarantor's financial benefit.

         GUARANTOR AGREES AS FOLLOWS:

1.       GUARANTEE. Guarantor unconditionally and irrevocably guarantees to
TRW the full and prompt payment when due of all indebtedness, liabilities and
obligations of SmarTire to TRW, whether present or future, primary or secondary,
absolute or contingent, direct or indirect, several, joint or joint and several,
(collectively, "Indebtedness") including, without limit, the payment obligations
and liabilities arising under or evidenced by the following:

         (a)  Termination Agreement dated as of August 31, 2001 by and between
              TRW and SmarTire;

         (b)  The $2,800,000.00 (USD) Secured Promissory Note dated August 31,
              2001 executed and delivered by SmarTire;

         (c)  All other documents executed in connection with the Termination
              Agreement.

together with expenses, costs and attorneys' fees, incurred by TRW in connection
with the enforcement of this Guaranty and/or any obligations of SmarTire to TRW.
TRW may have immediate recourse against Guarantor for full and immediate payment
of the Indebtedness at any time when the Indebtedness, or any portion, has not
been paid when due (whether by acceleration or otherwise). All payments by
Guarantor shall be made in lawful money of the United States of America and in
immediately available funds. Guarantor's obligations under this Guaranty are not
limited to any specific amount or part of the Indebtedness, including interest,
owed to TRW.

2.       NATURE OF GUARANTEE. This is a guarantee of payment and not of
collection. At any time when the Indebtedness, or any portion thereof, has not
been paid when due (whether by acceleration or otherwise) TRW can require that
Guarantor pay TRW the amounts owing under this Guaranty immediately, and TRW is
not required to collect first from SmarTire, or pursue any collateral or any
other person liable for the Indebtedness. No delay or stay in any acceleration
of the Indebtedness, as against SmarTire, due to the application of any
bankruptcy, insolvency or other law or proceeding shall be effective under this
Guaranty, and Guarantor agrees to pay immediately any amount of the Indebtedness
that would be due and payable but for such delay or stay. Guarantor's liability
for payment of the Indebtedness shall be a primary obligation and shall be
absolute and unconditional. Guarantor agrees that none of the following acts,
omissions or occurrences shall diminish or impair the liability of Guarantor in
any respect (all of which acts, omissions or occurrences may be done or occur
without notice to Guarantor):

         (a) Any extension, modification, indulgence, compromise, settlement or
variation of any of the terms of the Indebtedness.

         (b) Any assignment or transfer of any interest in any of the
Indebtedness.

         (c) The discharge or release of any obligations of SmarTire or any
other person now or hereafter liable on the Indebtedness, by reason of
bankruptcy or insolvency laws or otherwise.

         (d) The acceptance or release by TRW of any collateral, security or
other guaranty from Guarantor, SmarTire or any other person, or any settlement,
compromise or extension with respect to any such collateral, security or other
guaranty.

         (e) The application or allocation by TRW of payments, collections or
credits on the Indebtedness except to the amount of such payments, collections
or credits.

         (f) The creation of any new Indebtedness by SmarTire.

<PAGE>
         (g) The making of a demand, or absence of demand, for payment of the
Indebtedness, or giving, or failing to give, any notice of dishonor, protest,
presentment or non-payment or any other notice.

         (h) Any failure, omission or delay on the part of SmarTire, Guarantor
or any other person now or hereafter liable on the Indebtedness, or anyone
claiming by or through any of them, to comply with any instrument or agreement
relating to any of the Indebtedness.

         (i) To the extent permitted by law, any release or discharge, by
operation of law, of Guarantor from the performance or observance of any
obligation, covenant or agreement contained in this Guaranty.

         (j) Any merger or consolidation of SmarTire, Guarantor or any other
person now or hereafter liable on the Indebtedness, into or with any other
corporation or other entity, or any sale, lease or transfer of any of the assets
of SmarTire or Guarantor to any other person or entity.

         (k) Any other occurrence or circumstance which might otherwise
constitute a legal or equitable defense or discharge of the liabilities of a
guarantor or surety or which might otherwise limit recourse against Guarantor.

             The obligations of Guarantor set forth in this Guaranty constitute
full recourse obligations of Guarantor, enforceable against Guarantor to the
full extent of Guarantor's assets and properties. Guarantor's liability under
this Guaranty is independent of Guarantor's liability under any other guaranty
previously or subsequently executed by Guarantor or one of them, singularly or
together with others, as to all or any part of the Indebtedness, and may be
enforced for the full amount of this Guaranty regardless of Guarantor's
liability under any other guaranty.

3.       WAIVERS. Without limiting the generality of the foregoing, Guarantor
unconditionally waives

         (a) any right of subrogation to the rights of TRW against SmarTire
until the Indebtedness is paid in full;

         (b) TRW's acceptance of this Guaranty;

         (c) any set-offs or counterclaims that Guarantor may have against TRW
which would otherwise impair TRW's rights against Guarantor;

         (d) any demand or notice of any action that TRW takes regarding
SmarTire, anyone else, any collateral, or any Indebtedness, which Guarantor
might be entitled to by law or under any other agreement; and

         (e) any requirement of diligence on the part of anyone.

4.       REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants to
TRW as follows:

         (a) If Guarantor is a corporation, it represents that it is a
corporation duly organized, existing in good standing under the laws of its
state or province of incorporation, and that the execution and delivery of this
Guaranty and the performance of the duties and obligations under this Guaranty
are within Guarantor's corporate powers, have been duly authorized by all
necessary action by its board of directors or other governing bodies, and do not
contravene the terms of its articles of incorporation or bylaws or other
governing documents or agreements. If Guarantor is a co-partnership or limited
partnership, it represents that it is duly organized and existing under the laws
of its state or province of formation, and that the execution and delivery of
this Guaranty and the performance of the duties and obligations imposed under
this Guaranty are within Guarantor's partnership powers, have been duly
authorized by all necessary action of its partners, and do not contravene the
terms of its partnership agreement.

         (b) Guarantor is a subsidiary or otherwise an affiliate of SmarTire,
and such interest of Guarantor is not subject to any assignment, claim, lien,
encumbrance or agreement for sale, transfer or other disposition.

         (c) The execution and delivery of this Guaranty, and the performance of
the obligations imposed under this Guaranty, do not violate any law and do not
conflict with any agreement by which Guarantor is bound, and does not require
any consent or approval of any governmental authority or any third party. This
Guaranty is a valid and binding agreement, enforceable according to its terms.

         (d) All financial and other information, if any, furnished by Guarantor
to TRW is accurate and fairly reflects the financial condition of the persons or
entities to which they apply on their effective dates, including contingent
liabilities of every type, which financial condition has not changed materially
and adversely since those dates.

         (e) There are no actions, suits or proceedings, and no proceedings
before any arbitrator or by or before any governmental commission, board, bureau
or other administrative agency, pending or, to the best knowledge of Guarantor,
threatened against or affecting Guarantor, or any properties or rights of
Guarantor, which, if adversely determined, could have a materially adverse
effect upon the financial condition of Guarantor.

                                  Page 2 of 5
<PAGE>

         (f) Guarantor delivers this Guaranty based solely on Guarantor's
independent investigation of (or decision not to investigate) the financial
condition of SmarTire and is not relying on any information furnished by TRW.
Guarantor assumes full responsibility for obtaining any further information
concerning SmarTire's financial condition, the status of the Indebtedness or any
other matter which Guarantor may deem necessary or appropriate (now or later).
Guarantor waives any duty on the part of TRW, and agrees that Guarantor is not
relying upon or expecting TRW to disclose to Guarantor any fact now or later
known by TRW, whether relating to the operations or condition of SmarTire, the
existence, liabilities or financial condition of any co-guarantor of the
Indebtedness, the occurrence of any default with respect to the Indebtedness, or
otherwise, notwithstanding any effect such fact may have upon Guarantor's risk
under this Guaranty, or Guarantor's rights against SmarTire.

         (g) TRW has made no representation to Guarantor as to the
credit-worthiness of SmarTire, and Guarantor is satisfied with the means that
Guarantor has for obtaining from SmarTire, on a continuing basis, financial and
other information pertaining to SmarTire's financial condition.

5.       OTHER GUARANTORS. If more than one person or entity signs this
Guaranty, their duties and obligations under this Guaranty shall be joint and
several. All references to Guarantor shall be to each or any two or more of
them. Guarantor's duties and obligations under this Guaranty are joint and
several with any other guarantor of the Indebtedness. If TRW elects to enforce
its rights against all guarantors of the Indebtedness, that election shall not
release Guarantor from its duties and obligations under this Guaranty. The
compromise or release of any of the obligations of any of the other guarantors,
or SmarTire, shall not serve to waive, alter or release Guarantor's obligations.

6.       REINSTATEMENT. This Guaranty, and any agreement securing this
Guaranty, shall continue to be effective, or shall be automatically reinstated,
as the case may be, if at any time payment of all or any part of the
Indebtedness is rescinded or must otherwise be restored or returned by TRW upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of

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
in which SmarTire or TRW owns or controls more than fifty percent (50%) of the
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

        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.

                                    Article 2
                                 Licensed Rights

        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.

        4.1    Title: Nothing contained in this Agreement will be deemed to
convey to SmarTire the legal title to any TRW patent.

        4.2    Maintenance of Patents: TRW will have no obligation under this
Agreement (a) to file, prosecute, or maintain any TRW patent or (b) to respond
to or otherwise defend any action for reexamination or revocation of any TRW
patent.

                                    Article 5

SmarTire's rights under this license will cease to exist, without notice, if
SmarTire breaches of any of its obligations under either the Termination
Agreement or any of the other agreements referenced therein. In the event of
such termination of this Agreement, SmarTire will immediately cease using, for
any purpose whatsoever, any inventions covered by TRW Patents and any TRW
Proprietary Information, as defined in the Mutual Secrecy Agreement referenced
in the recitals of this Agreement.

                                    Article 6
                                   Assignment

        Neither party may assign or transfer this Agreement or any of its rights
or duties under this Agreement without the prior written consent of the other
party. For purposes of this Article, any change of control of SmarTire will be
considered to be a transfer of the Agreement.

                                    Article 7
                                     Notice

officers, directors, shareholders, employees, partners, agents, assigns,
successors, heirs, subsidiary corporations and related or affiliated
corporations, partnerships, persons and entities (collectively,

and SmarTire's Representatives from any and all Claims (as defined below) TRW
and its Representatives may or shall have against SmarTire and SmarTire's
Representatives arising out of, or in any way relating

<PAGE>

to: (i) the April 1998 Agreements; and (ii) the activities, events and/or
transactions undertaken in connection with, or pursuant to, the April 1998
Agreements.

        (b) Except as set forth in Section 2 below, SmarTire, for itself and its
Representatives, does hereby remise, release and forever discharge TRW and TRW's
Representatives from any and all Claims (as defined below) SmarTire and
SmarTire's Representatives may or shall have against TRW and TRW's
Representatives, including without limitation any and all Claims arising out of,
or in any way relating to: (i) the April 1998 Agreements; (ii) the activities,
events and/or transactions undertaken in connection with, or pursuant to, the
April 1998 Agreements; and (iii) the activities, actions or inactions of any TRW

        (c) SmarTire, for itself and its Representatives, does hereby remise,
release and forever discharge Dana Stonerook to the maximum extent permitted
under the Company Act (British Columbia) and SmarTire's Articles of
Incorporation from any and all Claims (as defined below) SmarTire may or shall
have against Dana Stonerook.

        (d) For the purposes hereof, "Claims" shall mean any and all present and
future claims, actions, causes of action, suits, cross claims, counterclaims,
sums of money, judgments, liabilities, obligations, damages, debts, losses,
indemnities, costs, expenses, penalties, accounts, reckonings, bonds, bills,
specialties, covenants, contracts, controversies, agreements, promises,
variances, trespasses, extents, executions, and demands of any kind and of any
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.

6.      GENERAL.

        (a) It is understood and acknowledged that the payment and promises set
forth herein represent the full and complete compromise and settlement of the
Claims. Nothing contained in this Release shall be construed as an admission of
liability on the part of any person.

        (b) Each party hereby acknowledges and agrees that this Release is
freely and voluntarily given without any duress or coercion and after it has
either consulted with legal counsel or been given the opportunity to do so, and
each party has carefully and completely read all of the terms and provisions of
this Release.

        (c) This Release constitutes the entire understanding between the
parties hereto with respect to the settlement and release of claims by the
parties hereto, and, except to the extent contemplated by Section 1(c) above,
any other agreement made by the parties at any time prior to the date hereof
with respect to the foregoing shall not be of any force or effect. The
provisions herein are, and shall be, binding upon, and shall inure to the
benefit of, the respective heirs, executors, administrators, assigns and
successors of the parties.

        (d) Each provision, covenant, obligation, warranty or representation
stated herein shall be deemed to be effective, operative, made, entered into and
taken in the manner and to the fullest extent permitted by law. If any provision
of this Release, or any covenant, obligation, warranty or representation
contained in this Release is determined by a court to be invalid or
