Expansion Leased
Premises")
------------------------ -------------- ------------------- -------------- -------------
</TABLE>

     (e)  A new section 4.7(A) is added to the Lease as follows:

          "4.7A - Lessor's Repair/Work for the Main Floor Exoansion Leased
           ---------------------------------------------------------------
          Premises
          --------

          The Main Floor Expansion Leased Premises are leased by the Lessee on
          an "as is where is" basis. Notwithstanding the foregoing, the Lessor
          shall, at its own cost, provide those repairs and improvements for the
          Main Floor Expansion Leased Premises detailed as follows:

          (a)  Demolition. Demolition of all interior partitions (excluding the
               ----------
               washrooms) and removal of flooring coverings and the T-bar
               ceiling.

          (b)  New Demising Walls. Construction of demising walls consistent
               ------------------
               with the demising walls constructed for the Initial Leased
               Premises as detailed in section 4.7(f) of the Lease.

          (c)  Windows. Installation of up to one exterior window per full bay,
               -------
               where desired by the Lessee, excluding bays where the washrooms
               or stairwells are located. Exterior windows installed along the
               Nelson Street frontage will have the same dimensions and sill
               heights as those installed for the Lessee on the second floor.
               Some or all of any exterior windows installed on the Mainland
               Street frontage will have sill heights higher than those
               installed on the second floor, and the possible vertical
               dimension of the windows will decrease somewhat moving towards
               the middle of the Building on Mainland Street.

               The Lessor and the Lessee agree that contractors for each of the
               Lessee and the Lessor may undertake work within the Main Floor
               Expansion Leased Premises concurrently. Prior to the Possession
               Date for the Main Floor Expansion Leased Premises the Lessee and
               the Lessor will each, acting reasonably, prepare, approve and
               commit to a schedule of dates by which the Lessor's Repairs/Work
               must be completed, subject to Force Majeure. The Lessor agrees
               that the Commencement Date for the Main Floor Expansion Leased
               Premises will be deferred for a period of time equivalent to any
               period of delay caused by the Lessor's failure to complete the
               Lessor's Repairs/Work in accordance with the approved schedule,
               but the Expiry Date shall remain the same and will not be
               extended. Notwithstanding the foregoing, the Lessee acknowledges
               that: 1) drywalling and taping of new demising walls cannot
               commence until the Lessee's contractor completes electrical and
               communications work in said new walls; and 2) exterior windows
               cannot be installed by the Lessor until the Lessee and Lessor
               jointly

<PAGE>

               establish the number of, location of, size and sill height of
               said windows, and that upon establishment of said design
               criteria, a reasonable amount of time is required to order
               windows and carry out installation of same. Therefore the Lessee
               agrees that the delays suffered by the Lessor in the completion
               of drywalling and taping of the new demising walls or
               installation of exterior windows (collectively the "Seagate
               Dependant Work") as a result of delays in the Lessee's electrical
               work, communications work or exterior wall design work, shall not
               result in an extension of the Commencement Date provided that the
               Lessor carries out the Seagate Dependent Work in a reasonable
               time period upon being in a position to do so."

          (f)  A new section 4.10 is added to the Lease as follows:

               "4.10 - Lessor's Seismic Upgrading

               The Lessor shall, at its own cost, seismically upgrade the
               Building on or before December 31, 2001 to achieve not less than
               75% of the current Vancouver building bylaw seismic requirements
               in both directions, as described in points 1 through 5 of the
               seismic upgrading recommendations prepared by Cameron Kemp of
               Omnicron which are attached as Schedule "D" to the Lease."

          (g)  A new section 4.11 is added to the Lease as follows:

               "4.11 - Deferment of Lessor's Repairs/Work on First Expansion
                ------------------------------------------------------------
               Premises Improvements
               ---------------------

               The Lessor and Lessee acknowledge and agree that the Lessee has
               requested that the Lessor defer the date that the Lessor
               commences the Lessor's Repairs/Work on the First Expansion Leased
               Premises from August 1, 2000 (the "Possession ("Date") to
               September 1, 2001 (the "Deferred Date"), the Deferred Date being
               the date the Lessor is required to commence the Lessor's
               Repairs/Work on the Third Expansion Leased Premises. It is the
               Lessee's intention that the Lessor's Repairs/Work be carried out
               to the First and Third Expansion Leased Premises by the Lessor
               concurrently. Accordingly, during the period from the Possession
               Date to the Deferred Date, the Lessee agrees to accept the First
               Expansion Leased Premises in an "as is" condition. For greater
               certainty, the Possession Date and Commencement Date for the
               First Expansion Leased Premises shall not be affected by this
               deferment and shall remain as described in section 2.1 of the
               Lease.

               During the four month period from the Deferred Date to December
               31, 2001, the Lessor shall be given possession of the First
               Expansion Leased Premises for the purposes of carrying out the
               Lessor's Repairs/Work to such area, and the Lessee shall be bound
               to pay Rent for the First Expansion Leased Premises in accordance
               with the Lease during such four month period, without set-off or
               deduction. For greater certainty, the Loan to be paid by the
               Lessor to the Lessee pursuant to sections 4.1 and 4.2 and the
               HVAC inducement to be paid by the Lessor to the Lessee pursuant
               to section 4.3 will not be payable until the Deferred Date in
               accordance with the terms of those sections."

          (h)  The parties agree that sections 4.1 and 4.2 relating to the
               Lessee Loan, section 4.3 relating to the HVAC inducement, section
               4.7(a), (b), (c), (d) and (e) relating to

               demolition and windows, section 4.8 relating to cash inducement
               in lieu of Lessor's Repairs/Work, section 4.9 relating to
               allowances for leasehold improvements and Schedule "C" will not
               apply to the Main Floor Expansion Leased Premises.

          (i)  The plan contained on page 1 of Schedule "A" of the Lease is
               deleted and the plan contained in Schedule "A" of this Amendment
               to Lease is substituted in its place.

          (j)  The schedule marked Schedule "D" attached to this Amendment to
               Lease is attached to and shall form part of the Lease as Schedule
               "D".

3.        Consent of Indemnifier
          ----------------------

          The Indemnifier hereby consents to this Amendment to Lease and hereby
ratifies and confirms its indemnity contained in the Lease, and the Indemnifier
hereby agrees that its indemnity shall remain in full force and effect in
accordance with its terms and, for greater certainty, applies to all of the
Demised Premises including, without limitation, the Main Floor Expansion Leased
Premises.

4.        Demise
          -------

          For greater certainty, and in consideration of the rents, covenants
and agreements contained in the Lease as hereby amended on the part of the
Lessee to be paid, observed and performed, the Lessor does hereby demise and
lease unto the Lessee as and from the Amendment Date, the Demised Premises
including the Main Floor Expansion Leased Premises, for and during the Term of
the Lease, and any renewals thereof and the Lessee hereby covenants and agrees
to pay the rents, and observe and perform the covenants and agreements in the
Lease as hereby amended on its part to be paid, observed and performed.

5.        Lease Ratified and Confirmed
          ----------------------------

          Except as hereby expressly amended the Lease is hereby ratified and
confirmed by the Lessor and the Lessee to the effect and with the intent that
the Lease and this Amendment to Lease shall be read and construed as one
document as if the Main Floor Expansion Leased Premises had been demised and
leased by the Lease together with the Original Premises all on the same terms
and conditions and subject to performance of all the covenants set forth in the
Lease, as hereby amended.

6.        Enurement
          ---------

          This Amendment to Lease shall enure for the benefit of and be binding
on the heirs, executors, administrators, successors and permitted assigns (as
the case may be) of the parties hereto to the same extent as binding upon the
parties hereto.

7.        Execution.
          ---------

          Each of the Lessor, the Lessee and the Indemnifier confirm and agree
that this Amendment to Lease has been executed by its authorized signatories and
if only one signatory has signed this Amendment to Lease, each is authorized by
its articles of incorporation or other constating documents to execute leases
