 This Guarantee dated as of March 8, 2004 made by TSI MEDICAL
  CORP. (the “Guarantor”) to and in favour of THE CHARLES F.
  WHITE CORPORATION (the “Lender”) as lender under the Loan Agreement
  hereinafter referred to. 


WHEREAS: 

	 A.      	 689158 B.C. Ltd. (the “Borrower”)
        has entered into a loan agreement with the Lender dated as of the date
        hereof (as such agreement may at any time or from time tot time be amended,
        supplemented, extended or otherwise modified or restated, the “Loan
        Agreement”) pursuant to which a loan in the principal amount
        of US$500,000 is being advanced by the Lender to the Borrower (the
        “Loan”). 

	 	 
	 B.      	 It is a condition of the advance of the Loan by
        the lender to the Borrower that the Guarantor execute and deliver this
        guarantee to and in favour of the Lender as collateral security for the
        payment and performance of the Guaranteed Obligations (as hereinafter
        defined). 



 NOW THEREFORE WITNESSETH that in consideration of the
  payment of the sum of $1.00 in lawful money of Canada by the Lender to the
  Guarantor and other good and valuable consideration, the receipt and sufficiency
  of which is hereby acknowledged, the Guarantor herby covenants, declares and
  agrees as follows: 

	 1.      	 Guarantee. The Guarantor hereby
        irrevocably and unconditionally guarantees the due and punctual performance
        and payment to the Lender, whether at stated maturity, by acceleration
        or otherwise, of all obligations of the Borrower to the Lender, now or
        hereafter existing under or pursuant to the Loan Agreement, whether for
        principal, interest, bonus, fees, expenses, indemnity or otherwise, and
        any and all out-of-pocket expenses (including counsel fees and disbursements
        on a solicitor and own client basis) incurred by the Lender in enforcing
        any of its rights under this guarantee (such obligations being herein
        called the “Guaranteed Obligations”) 

	 
	 2.      	 Absolute Liability. The Guarantor
        guarantees that the Guaranteed Obligations will be paid and performed
        strictly in accordance with the terms of the Loan Agreement. The liability
        of the Guarantor under this guarantee shall be absolute and unconditional
        irrespective of: 

	 
	 	 a.     
      
	 the lack of validity or enforceability of any terms
        of the Loan Agreement or any security granted to the Lender by the Borrower
        or any other person or persons pursuant to the terms of the Loan Agreement;
      

	 
	 	 b.      
	 any consent by the Borrower or any other person
        as to the amount of the Guaranteed Obligations or the validity or enforceability
        of any terms of the Loan Agreement; 

	 
	 	 c.      
	 any defence, counter-claim or right of set-off available
        to the Borrower; 

	 
	 	 d.      
	 any extension of the time or times for payment of
        the Guaranteed Obligations or any other indulgences the Lender may grant
        to the Borrower; 

	 
	 	 e.      
	 any dealings with the security which the Lender
        holds or may hold pursuant to the terms and conditions of the Loan Agreement,
        including the taking and giving up of securities, the accepting of compositions
        and the granting of releases and discharges; 








 

	 	 f.      	 the assignment of all or any part of the benefits
        of this guarantee; 

	 
	 	 g.      	 any modification or amendment of or supplement to
        the Guaranteed Obligations or the Loan Agreement, including, without limitation,
        any assignment or assumption of the commitment or commitments of the Lender
        under the Loan Agreement and any increase or decrease in the principal,
        the rates of interest or other amounts payable under the Loan Agreement;
        or 

	 
	 	 h.      	 any other circumstances which might otherwise constituted
        a defence available to or a discharge of a guarantor, the Borrower or
        any other person in respect of the Guaranteed Obligations, or of the Guarantor
        in respect to this guarantee. 





	 3.      	 Remedies. The Guarantor agrees that the Lender
        shall not be bound to seek or exhaust its recourses against the Borrower
        or any other person or to realize on any security it may hold in respect
        of the Guaranteed Obligations before being entitled to payment hereunder.
        Should the Lender elect to realize on any security it may hold, either
        before, concurrently with our after demand for payment under this guarantee,
        the Guarantor shall have no right of discussion or division. 

	 
	 4.      	 Amount of Guaranteed Obligations. Any account
        settled or stated by or between the Lender and the Borrower or, if any
        such account has not been so settled or stated immediately before demand
        for payment under this guarantee, any account thereafter stated by the
        Lender shall, in the absence of demonstrated error, be accepted by the
        Guarantor as conclusive evidence of the amount of the Guaranteed Obligations
        which at the date of the account so settled or stated is due by the Borrower
        to the Lender or remains unpaid by the Borrower to the Lender. 

	 
	 5.      	 Payment on Demand. The Guarantor shall make
        payment to the Lender of the amount of the Guaranteed Obligations forthwith
        after demand therefore is made in writing to it, and such demand shall
        be deemed to have been effectively made when an envelope containing such
        demand addressed to the Guarantor at: 810 Peace Portal Drive, Suite 202,
        Blaine, Washington 98230, Attention: ________________ , is personally
        delivered to such address or is deposited, postage prepaid and registered,
        in any post office within or outside Canada. The indebtedness of the Guarantor
        hereunder shall bear interest from the date of such demand to the date
        of payment thereof in full at the rate or rates of interest applicable
        to the Guaranteed Obligations under and calculated in the manner provided
        in the Loan Agreement. 

	 
	 6.      	 Subrogation and Repayment. Upon receipt by
        the Lender of any payments on account of liability under this guarantee,
        whether by realization on security or otherwise, the Guarantor shall not
        be entitled to claim repayment against the Borrower until the Lender’s
        claims against the Borrower in respect of the Guaranteed Obligations have
        been repaid in full. In the case of the liquidation, winding-up or bankruptcy
        of the Borrower (whether voluntary or compulsory) or in the event that
        the Borrower shall make a bulk sale of any of the Borrower’s assets
        within the provisions of any bulk sales legislation or any composition
        with creditors or scheme of arrangement, the Lender shall have the right
        to rank in priority to the Guarantor for its full claims in respect of
        the Guaranteed Obligations and receive all dividends or other payments
        in respect thereof until its claims in respect of the Guaranteed Obligations
        have been paid in full, and the Guarantor shall continue to be liable,
        less any payments made by or on behalf of the Guarantor, for any balance
        which may be owing to the Lender by the Borrower. In the event of the
        valuation by the Lender of any of its security or the retention thereof
        by the Lender or both, such valuation or retention, or both, shall not,
        as between the Lender and the Guarantor, be considered as a purchase of
        such security, or as payment or satisfaction or reduction of the Guaranteed
        Obligations or any part thereof. If any amount shall be paid to the Guarantor
        on account of any subrogation rights at any time when all the Guaranteed
        Obligations shall not have been paid in full, such amount shall be held
        in trust for the benefit of the Lender and shall forthwith be paid to
        the Lender to be credited and applied upon the Guaranteed Obligations,
        whether matured or unmatured. 












	 7.      	 Assignment and Postponement. 
	 
	 	 	 (1)     
      
	 All obligations, liabilities and indebtedness of
        the Borrower to the Guarantor of any nature whatsoever, and all security
        therefore, (the “Subject Indebtedness”) are hereby
        assigned and transferred to the Lender as continuing and collateral security
        for the obligations of the Guarantor hereunder. The Guarantor shall not
        assign the Subject Indebtedness or any part thereof to any person other
        than the Lender or as permitted pursuant to the Loan Agreement. 

	 
	 	 	 (2)      
	 From and after demand by the Lender pursuant to
        Section 5 hereof, the Subject Indebtedness shall be held in trust by the
        Guarantor for the Lender and shall be collected, enforced or proved subject
        to and for the purposes of this guarantee, and any payments received by
        the Guarantor in respect thereof shall be segregated from other funds
        and property held by the Guarantor and forthwith paid over to the Lender
        on account of the Guaranteed Obligations. 

	 
	 	 	 (3)      
	 From and after demand by the Lender pursuant to
        Section 5 hereof, the Lender shall be entitled to receive payment of the
        Guaranteed Obligations in full before the Guarantor shall be entitled
        to receive any payment on account of the Subject Indebtedness. The Subject
        Indebtedness shall not be released or withdrawn by the Guarantor unless
        the Lender’s written consent to such release or withdrawal is first
        obtained, and the Guarantor shall not permit the prescription of the Subject
        Indebtedness by any stature of limitations or ask for or obtain any security
        or negotiable paper for or other evidence of the Subject Indebtedness
        except for the purpose of delivering the same to the Lender. 

	 
	 8.      	 No Prejudice to the Lender. The
        Lender shall not be prejudiced in any way in the right to enforce any
        provision of this guarantee by any act or failure to act on the part of
        the Borrower. The Lender may, at any time and from time to time, without
        any consent of or notice to the Guarantor and without impairing or releasing
        the Guarantor from its obligations hereunder: 

	 
	 	 a. 
	change the manner, place or terms of payment or change or extend
      time of payment of, or renew or alter, the Guaranteed Obligations; 
	 
	 	 b.
	 release anyone liable in any manner under or in respect of
      the Guaranteed Obligations; 
	 
	 	 c. 
	exercise or refrain from exercising any rights against the Borrower
      or the Guarantor or any other person; and 
	 
	 	 d.
	 apply to the Guaranteed Obligations any sums from time to time
      received. 
	 
	 9.      	 Rights of Set-Off. To the fullest
        extent permitted by law, the Guarantor shall make all payments hereunder
        without regard to any defence, counter-claim or right of set-off available
        to it. Upon the making of a demand for payment hereunder, the Lender is
        hereby authorized at any time and from time to time, to the fullest extent
        permitted by law, to set-off and apply any deposits (general or special,
        time or demand, provisional or final) at any time held or other indebtedness
        at any time owing by the Lender to or for the credit or the account of
        the Guarantor against the Guaranteed Obligations and other amounts due
        to the Lender hereunder irrespective of whether or not the Lender shall
        have made any demand under this guarantee and although such Guaranteed
        Obligation and other amounts may be contingent and unmatured. The rights
        of the Lender under this Section 9 are in addition, without prejudice
        and supplemental to any other rights and remedies (including, without
        limitation, other rights of set-off) which the Lender may have. 








 

	 10.      	 No Recourse. Any right of subrogation
        acquired by the Guarantor by reason of payment under or pursuant to this
        guarantee shall not be exercised until the Guaranteed Obligations and
        other amounts due to the Lender hereunder have been paid or repaid in
        full to the Lender, and shall be no greater than the right held by the
        Lender and the Guarantor shall have no recourse against the Lender for
        any invalidity, non- perfection or unenforceability of any security held
        by the Lender or any irregularity or defect in the manner or procedure
        by which the Lender realizes on such security. 

	 
	 11.      	 Continuing Guarantee. This guarantee
        shall continue to be effective or be reinstated, as the case may be, if
        at any time any payment of any of the Guaranteed Obligations is rescinded
        or must otherwise be returned by the Lender upon the insolvency, bankruptcy
        or reorganization of the Borrower or otherwise, all as though such payment
        had not been made. 

	 
	 12.      	 Supplemental Security. This guarantee
        is in addition, without prejudice and supplemental to all other guarantees
        and securities held, or which may hereafter be held, by or for the Lender.
      

	 
	 13.      	 Representations.

	 16.      	 Successors, etc. This guarantee
        shall extend to and enure to the benefit of the Lender and its successors
        and assigns and shall be binding upon the Guarantor and its successors
        and permitted assigns. This guarantee shall not be assigned by the Guarantor
        without the Lender’s written consent. All rights of the Lender hereunder
        shall be assignable in accordance with the terms of the Loan Agreement.
      








 

	 17.      	 Notices. All notices, requests, demands,
        directions and communications (“notices”) hereunder
