      any kind by the Borrower, any Material Subsidiary, the Lender or any other
      Person or any other circumstance whatsoever, whether similar or dissimilar
      to the foregoing, which might, but for the provisions of this Section 3,
      constitute a legal or equitable discharge, limitation or reduction of the
      Guarantors obligations hereunder (other than the irrevocable and
      unconditional payment in full of all of the Obligations).                                                                                                                                                                                                                                                                                                                                                             
| |    

The foregoing provisions apply (and
the foregoing waivers will be effective) even if the effect of any action (or
failure to take action) by the Lender is to destroy or diminish the Guarantors
subrogation rights, the Guarantors right to proceed against the Borrower for
reimbursement, the Guarantors right to recover contribution from any other
guarantor or any other right or remedy.

|4. | Release of Obligations. This Guarantee will remain in
      full force and effect until the Obligations are irrevocably and
      unconditionally performed and paid in full.

|5. | Validity of Agreements. The Guarantor will not contest
      or otherwise challenge the legality, validity or enforceability of any
      term, condition or other provision contained in the Credit Documents. The
      Guarantor represents to the Lender that it is familiar with and consents
      to the terms and conditions of the Credit Documents.

|6.  | Assumption of Authority. The
      Lender is entitled to assume, notwithstanding any investigation by or on
      behalf of the Lender the power and authority of the officers, directors,
      agents or other Persons acting or purporting to act on behalf of the
      Borrower or any Material Subsidiary, and any Obligations made or created
      in reliance upon the exercise of such power or authority will be
      guaranteed hereunder.

|9.  | No Waiver. No delay on the part
      of the Lender in exercising any of its options, powers or rights, or

      waiver of any of the Lenders rights hereunder, and no modification or
      amendment of this Guarantee, will be deemed to be made by the Lender
      unless the same will be in writing, duly signed by the Lender and the
      Guarantor, and each such waiver, if any, will apply only with respect to
      the specific instance involved, and will in no way impair the rights of
      the Lender or the liabilities of the Guarantor to the Lender in any other
      respect at any other time.

|10. | Guarantee of all Credit Obtained:
      Indemnity.All moneys and credits in fact borrowed or
      obtained by the Borrower from the Lender under the Credit Documents will
      be deemed to form part of the Obligations notwithstanding any incapacity,
      disability or lack or limitation of status or power of the Borrower or of
      the directors, officers, employees, partners or agents thereof, or that
      the Borrower may not be a legal entity, or any irregularity, defect or
      informality in the borrowing or obtaining of such moneys or credits. If
      any amount in respect of the Obligations is not recoverable from the
      Guarantor hereunder on the basis of a guarantee, then, notwithstanding any
      other provision hereof, the Guarantor will indemnify and save harmless the
      Lender from and against any and all losses, damages, costs, expenses or
      liabilities suffered or incurred by the Lender resulting or arising from
      or relating to any failure of the Borrower or any other Material
      Subsidiary to unconditionally and irrevocably pay in full or fully perform
      the Obligations as and when due provided that the amount of such
      indemnification shall not exceed the amount of such Obligations and any
      amounts due and owing hereunder.

|11. | Stay of Acceleration. If
      acceleration of the time for payment, or the liability of the Borrower to
      make payment, of any amount specified to be payable by the Borrower in
      respect of the Obligations is stayed, prohibited or otherwise affected
      upon the insolvency, bankruptcy, reorganization or winding-up of the
      Borrower or any moratorium affecting the payment of the Obligations, all
      such amounts otherwise subject to acceleration or payment will nonetheless
      be deemed for all purposes of this Guarantee to be and to become due and

|12. | Reinstatement. If, at any time,
      all or any part of any payment previously applied by the Lender to any
      Obligation is or must be rescinded or returned by the Lender for any
      reason whatsoever (including the insolvency, bankruptcy, or reorganization
      of the Borrower or any other Material Subsidiary), such Obligation will,
      for the purpose of this Guarantee, to the extent that such payment is or
      must be rescinded or returned, be deemed to have continued in existence,
      notwithstanding such application by the Lender and this Guarantee will
      continue to be effective or be reinstated, as the case may be, as to such
      Obligation, all as though such application by the Lender had not been
      made.

|13. | Assignment and Postponement.Following the
      occurrence and during the continuance of a Default or an Event of Default,
      all present and future indebtedness and liability of the Borrower or any
      other Material Subsidiary to the Guarantor is hereby assigned by the
      Guarantor to the Lender and postponed to the Obligations and all moneys
      received by the Guarantor in respect thereof will be received in trust for
      and, unless prior written authorization from the Lender to the contrary
      will have been obtained by the Guarantor, will be paid over to the Lender
      upon demand by the Lender. If the Lender receives from the Guarantor a
      payment or payments in full or on account of the liability of the
      Guarantor hereunder, the Guarantor will not be entitled to claim repayment
      against the Borrower or any other Material Subsidiary until the Lender's
      claims against the Borrower have been irrevocably and unconditionally paid
      in full. In case of liquidation, winding up or bankruptcy of the Borrower
      or any other Material Subsidiary (whether voluntary or involuntary) or any
      composition with creditors or scheme of arrangement, the Lender will have
      the right to rank for its full claims and receive all dividends or other
      payments in respect thereof in priority to the Guarantor until the claims
      of the Lender have been irrevocably and unconditionally paid in full, and
      the Guarantor will continue to be liable hereunder for any balance which
      may be owing to the Lender by the Borrower or any other Material
      Subsidiary. In the event of the valuation by the Lender of any of its
      security and/or the retention thereof by the Lender, such valuation and/or
      retention will not, as between the Lender and the Guarantor, be considered
      as a purchase of such security, or as payment or satisfaction of the
      Obligations or any part thereof. The foregoing provisions of this Section
      13 will not in any way limit or lessen the liability of the Guarantor
      under any other section of this Guarantee.

|14. | No Subrogation.Notwithstanding any payment made
      by the Guarantor under this Guarantee or any setoff or application of
      funds of the Guarantor by the Lender the Guarantor will have no right of
      subrogation to, and waives, to the fullest extent permitted by Law, any
      right to enforce any remedy which the Lender now has or may hereafter have
      against the Borrower or any other Material Subsidiary, until all of the
      Obligations have been irrevocably and unconditionally paid in full; and
      until that time, the Guarantor waives any benefit of, and any right to

|15. | Foreign Currency Obligations.The Guarantor will make
      payment relative to each Obligation in the currency (the "Original
      Currency") in which the Borrower is required to pay such Obligation.
      If the Guarantor makes payment relative to any Obligation to the Lender in
      a currency (the "Other Currency") other than the Original Currency
      (whether voluntarily or pursuant to an order or judgment of a court or
      tribunal of any jurisdiction), such payment will constitute a discharge of
      the liability of the Guarantor hereunder in respect of such Obligation
      only to the extent of the amount of the Original Currency which the Lender
      is able to purchase at Vancouver, British Columbia with the amount it
      receives on the date of receipt. If the amount of the Original Currency
      which the Lender is able to purchase is less than the amount of such
      currency originally due to it in respect to the relevant Obligation, the
      Guarantor will indemnify and save the Lender harmless from and against any
      loss or damage arising as a result of such deficiency. This indemnity will
      constitute an obligation separate and independent from the other
      obligations contained in this Guarantee, will give rise to a separate and
      independent cause of action, will apply irrespective of any indulgence
      granted by the Lender and will continue in full force and effect
      notwithstanding any judgment or order in respect of any amount due
      hereunder or under any judgment or order.

|16. | Taxes and Set-off by Guarantor.All payments to be made
      by the Guarantor hereunder will be made without set-off or counterclaim
      and without deduction for any taxes, levies, duties, fees, deductions,
      withholdings, restrictions or conditions of any nature whatsoever. If at
      any time any applicable Law, regulation or international agreement
      requires the Guarantor to make any such deduction or withholding from any
      such payment, the sum due from the Guarantor with respect to such payment
      will be increased to the extent necessary to ensure that, after the making
