be  made  good  to  the  extent of enabling the Sub-Tenant to use and occupy the
Subleased  Premises.

(ii)     if  the damage be such that the Subleased Premises are wholly unfit for

destruction  or  damage  and  the  Rent  and  all  other  payments for which the
Sub-Tenant  is  liable under the terms of this Sublease shall be apportioned and
paid  in  full  to  the  date  of  such destruction or damage. In the event that
neither  the  Sub-Landlord  or  the Sub-Tenant so terminates this Sublease, Rent
shall  abate from the date of the happening of the damage until the damage shall
be  made  good  to  the  extent of enabling the Sub-Tenant to use and occupy the

(iii)     if  in the opinion of the Sub-Landlord, the damage can be made good as
aforesaid  within  one  hundred  and  twenty (120) days of the happening of such
destruction  or  damage,  and the damage is such that the Subleased Premises are
capable of being partially used for the purposes for which subleased, until such
damage  has  been  repaired, Rent shall abate in the proportion that the part of
the  Subleased  Premises  rendered unfit for occupancy bears to the whole of the

the  same  rental  as  provided  in  this  Sublease.

8.04      The  Sub-Landlord  shall have a period of thirty (30) days in which to

within  such sixty (60) day period the Sub-Landlord's consent to such assignment
or  sub-subleasing shall be deemed null and void and the Sub-Tenant shall not be
permitted to assign or sub-sublet without again conforming to all of the express
provisions  hereof.

to  exist (or, in the case of a default which cannot with due diligence be cured
within  a  period  of  thirty  (30)  days,  the Sub-Tenant shall fail to proceed
promptly  after  giving  of  such  notice  to  begin  to  cure  the  same);  or

creditors,  or shall become bankrupt, or shall make application for relief under
the  provisions  of any statute now or hereafter in force concerning bankrupt or

then  and  in  any of such cases the then-current month's Rent together with the
Rent  for  the  three  (3) months' next ensuing shall immediately become due and

     (b)     The  Sub-Tenant  waives and renounces the benefit of any present or
future  statute  purporting  to  limit  or  qualify  the Sub-Landlord's right to
distrain  and agrees with the Sub-Landlord that in any of the cases described in
paragraph  (a)  the Sub-Landlord in addition to the other rights hereby reserved
to  it shall have the right to enter the same Subleased Premises as agent of the
Sub-Tenant either by force or otherwise without being liable for any prosecution
therefor  and  to  take  possession  of any goods and chattels whatsoever on the
Subleased Premises and to sell the same at public or private sale without notice

all  losses,  damages,  costs  and expenses whatsoever suffered by reason of the
Sublease  having  been  prematurely  determined.

cases  described  in subparagraph (a) hereof the Sub-Landlord in addition to the
other  rights  hereby reserved to it shall have the right to enter the Subleased
Premises  as  agent of the Sub-Tenant either by force or otherwise without being
liable  for  any  prosecution  therefor and to re-sublease or sub-sublet, as the

of the Sub-Tenant's estate herein whose mortgage, charge or encumbrance has been
consented to by the Sub-Landlord and who has filed with the Sub-Landlord written
notice  of  his  mortgage,  charge  or  encumbrance and specified an address for
service, (such mortgagee, chargee or holder of an encumbrance being hereinafter,
in  this  Section  9.02,  called  "the Mortgagee") unless the Sub-Landlord shall
first have given to the Mortgagee notice of the default or contingency entitling
the  Sub-Landlord  to  re-enter,  terminate or forfeit this Sublease, and of the
Sub-Landlord's  intention  to take such proceedings, and requiring the Mortgagee
to cure the default. The Mortgagee shall thereafter have a period of thirty (30)
days within which to cure the default or contingency, if the same can reasonably
be  cured  within such period, or within which to begin curing of the same if it
cannot  be reasonably cured within such period, and shall be permitted access to
the Subleased Premises for that purpose. If the Mortgagee so cures or begins and
continues  diligently  to endeavour to cure such default or contingency it shall
be  entitled  to  continue  as  Sub-Tenant hereunder for the balance of the term
remaining  at  the  date  of  the notice of default, provided that it attorns as
Sub-Tenant  to the Sub-Landlord and undertakes to be bound by and to perform and

rights  of any mortgagee, chargee, or encumbrances of the Sub-Tenant's estate to
continue  as  Sub-Tenant  hereunder.

10.01     No  waiver  by the Sub-Landlord or the Sub-Tenant of any breach by the

other  party  of any of its obligations, agreements or covenants hereunder shall
be  a  waiver  of any subsequent breach or of any other obligation, agreement or
covenant,  nor  shall  any  forbearance by the Sub-Landlord or the Sub-Tenant to
seek a remedy for any breach by the other party be a waiver by the former of its
rights  and  remedies  with  respect  to  such  or  any  subsequent  breach.

the  Sub-Landlord  (Hazco  Environmental  Services  Ltd.) and the Landlord (Cane
Holdings  Ltd.)  on  May  8th,  2000 differs from the Sub-Lease Agreement in the
following  ways:

1.     The Sub-Tenant had paid the Sub-Landlord $14,461 for payment of first and
last  months'  rent, plus Goods and Services Tax in accordance with Article 3 of
the  Offer  to  Sub-Lease.  This  is  not  mentioned In the Sub-Lease Agreement.

including  licenses  and  maintenance are the sole responsibility of the Tenant.

"All provisions of (the) Offer shall survive the completion of this transaction.

                          INTERIOR CLEANING OF BUILDING

With reference to Article 4.02 of the Sub-Lease Agreement, "cleaning, lighting,
heating  If  "cleaning"  refers  to  external cleaning of the building, that is
fine,  However, if "cleaning" refers to the interior of the building, because of
the  nature  of  our  business and our absolute need to ensure protection of our
intellectual  property  including  unescorted  access  to  our  offices,  is  of
extremely  high  importance  to  us.

The  Sub-Tenant  has  already made arrangements ;of the internal cleaning of the
building,  including  interior  window  washing,  and  is solely responsible for
payment  for  such  services.  The  Sub-Tenant  will  keep proper and sufficient
records  and  accounts of all costs associated with the interior cleaning of the
building,  such  records  to  be  made  available  at  our  offices by our Chief
Financial  Officer  to  the  Sub-Landlord  at  any  reasonable  time.
