                   If Landlord does not take the responsibility for the
                   implementation of the Works, the Landlord shall diligently

                   Work and the Landlord shall remedy such deficiencies, failing
                   which the Tenant shall remedy such deficiencies and set-off
                   such cost or costs against the Gross Rent due and payable.

                   leasehold improvements belong to the Landlord and that the
                   Tenant shall not be obliged to demolish them at the expiry of

                   (Option to Expand), the Landlord consents to grant to the
                   Tenant the right, at any time during the Term of this Lease
                   or the renewal thereof, of a first refusal right on any
                   available space, at a rate equivalent to that offered by a
                   BONA FIDE third party for such space.

                   The Landlord undertakes to give the Tenant written notice

                   right of first refusal.

                   The present clause shall apply each time any available space
                   becomes available, whether or not the Tenant has exercised
                   the right herein contained.

                   The Term of the Lease for any expansion shall be co-terminus

                   date, failing which, this option to renew will become null

                   of the last preceding yearly gross rate paid by the Tenant.
                   For calculation purposes, this preceding yearly gross rate
                   shall exclude any financing of the Works included in the

                   months before the last day of the Term of the Lease, failing
                   which, the Tenant's right to terminate the Lease shall become
                   null and void and of no effect.

                   In the event that the Lease is terminated in accordance with
                   the foregoing, the Tenant agrees to pay the Landlord a sum
                   corresponding, if applicable, to the remaining non amortized

                   the Tenant shall have a right of first occupation of the
                   whole or any divisible part of such new space at the then
                   prevailing and competitive market gross rate and for a term
                   not to exceed the present Term of the Lease or any renewal
                   thereof.

SECTION 25         ARBITRATION

                   If, for any reason relating to the substance and / or
                   interpretation of any Term or Condition the Lease, the
                   Landlord and the Tenant fail to reach a fast agreement, the
                   settlement thereof shall be referred to a Board of three
                   arbitrators, one to be appointed by each of the Landlord and
                   the Tenant and a third arbitrator to be appointed in writing
                   by the first two-named arbitrators; if the Landlord or the
                   Tenant shall refuse or neglect to appoint an arbitrator
                   within TEN (10) days after the other shall have served a
                   written notice upon the party so refusing or neglecting to
                   make such appointment, the arbitrator first appointed shall,
                   at the request of the party appointing him, proceed to decide
                   on the matter as if he were a single arbitrator appointed by
                   both the Landlord and the Tenant for the purpose. If two
                   arbitrators are so appointed within the time prescribed and
                   they do not agree within a period of TEN (10) days from the
                   date of appointment of the second arbitrator upon the
                   appointment of the third arbitrator, then upon the
                   application of either the Landlord or the Tenant, the third
                   arbitrator shall be appointed by a Judge of the Superior
                   Court of Quebec

                   the arbitrators or the majority of them or by the single
                   arbitrator, as the case may be, shall be final and binding
                   upon the Landlord and the Tenant, and their respective
                   successors and assigns.

                   Each party shall pay the fees and expenses of the arbitrator

                   third arbitrator. The provisions of this section shall be
                   deemed to be a submission to arbitration within the provision
                   of the Civil Code of Quebec and the Code of Civil Procedure
                   of the Province of Quebec.

                   maintain and keep the Leased Premises, including all
                   facilities, equipment and services within and exclusive to
                   the rented areas, in such good order and condition as they
                   would be kept by a careful owner, and shall promptly make all
                   the necessary required repairs by the normal use of the
                   Premises and their related electrical or mechanical systems.

                   The Landlord shall be responsible for all latent or
                   structural defects, design or construction defects, or for

                   leased shall be destroyed or damaged by fire, lightning or

                   insured against under the provisions of Section 28, then and
                   in every such event:

                   If the damage or destruction, in the opinion of the Tenant,
                   is such that the portion or the whole of the rented premises
                   are rendered unfit for occupancy or unsafe to use and occupy,
                   then notice of such shall be given by the Tenant to the
                   Landlord within three days of the happening of such damage or
                   destruction which will have to be repaired, with prompt and
                   reasonable diligence, within thirty (30) days following
                   reception of the notice by the Landlord and the rent shall
                   abate from the date of the happening of the damage until
                   final and operational restoration of the rented Premises.

                   If Landlord, acting reasonably, refuses to repair such damage
                   or destruction, or cannot comply with the above described
                   delay, the Tenant shall then have the right to terminate its
                   Lease at the date of the occurrence of the damage or
                   destruction, or claim from the Landlord an abatement of its
                   rent proportional to the damaged or destructed surface until
                   the whole Premises is re-established in its original and
                   operational capacity.

SECTION 29         INSURANCE

                   The Tenant covenants that nothing will be done or omitted by
                   it whereby any policy shall be cancelled or the Leased

                   (i)                "all risks" (including flood and

                                      insured against pursuant to this Section
                                      28 and other perils commonly insured
                                      against by prudent tenants operating under
                                      similar circumstances; and

                   (iii)              any other form of insurance as the
                                      Landlord may reasonably require from time
                                      to time in form, in whatever amounts and
                                      for insurance risks against which a
                                      prudent tenant under similar circumstances

                   Certificate of insurance shall be delivered to the Landlord
                   as well as evidence of renewal or replacement if any at least
                   THIRTY (30) days prior to the date fixed for cancellation or

                   Such insurance shall be contracted with insurers and in
                   conformity with terms reasonably satisfactory to the Landlord
                   and pursuant to which the

                   Landlord shall be named as an additional insured to the
                   extent indemnified herein.

                   The Tenant shall obtain from the insurers under such
                   policies, undertakings to notify the Landlord in writing at
                   least thirty (30) days prior to any cancellation or
                   expiration thereof.

                   Without limiting the foregoing; the Tenant undertakes to
                   insure the portion of the Building where the Leased Premises
                   are located against any damages to or loss, theft, or
                   destruction of the property.

                   Landlord shall keep the Building, including all improvements
                   insured against damage and destruction by fire, earthquake,
                   vandalism, and other perils in the amount of the full
                   replacement value of the Building, as the value may exist
                   from time to time. The insurance shall include an extended
                   coverage endorsement of the kind required by an institutional
                   lender to repair and restore the Building. Landlord shall
                   maintain contractual and comprehensive general liability
                   insurance, including public liability and property damage,
                   with a minimum combined single limit of FOUR MILLION DOLLARS
                   ($ 4,000,000.00) for personal injuries or deaths of persons
                   occurring in or about the Building and Leased Premises.

                   Notwithstanding the foregoing, with respect to liability for
                   fire or explosion, for which the Parties maintain a system of
                   coverage on their respective property, each party hereto
                   waives its rights, and the rights of its subsidiaries and
                   affiliates, to recover from the other party hereto and its
                   subsidiaries and affiliates for loss or damage to such
                   party's building, equipment, improvements and other property
                   of every kind and description resulting from fire, explosion
                   or other cause normally covered in standard broad form
                   property insurance policies. This clause shall survive
                   termination of this Lease.

                   accepted Offer to Lease in the absence of a Master Lease)
                   only by presenting a deed which shall constitute a separate
