            b)    at the time of giving such notice the Tenant shall not be in
                  breach of any covenant or condition herein contained; and

            c)    the Tenant has duly and regularly throughout the initial Term
                  and First Renewal Term observed and performed the covenants
                  and conditions herein contained;

            then the Landlord shall grant to the Tenant at the Tenant's expense
            a renewal lease of the Leased Premises for a second term of that
            number of years specified in Article 1.1(i) upon the same terms and
            conditions as are herein contained, save and except this covenant
            to, renew, any Tenant Improvement Allowance and save and except the
            Annual Base Rent which shall be the greater of the Current Market
            Rent for the Leased Premises with its Leasehold Improvements (having
            regard to the duration of the renewal term) and the sum of the
            Annual Base Rent payable for the last three (3) months before the
            expiry of the First Renewal Term to agree upon such Current Market
            Rent, the determination of such Current Market Rent shall be
            referred to a single arbitrator if the parties hereto agree upon
            one, otherwise to a board of three (3) 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 seven (7) clear 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
            determine such rent as if he were a single arbitrator appointed by
            both the Landlord and Tenant for the purpose. If two (2) arbitrators
            are so appointed within the time prescribed and they do not agree
            upon the appointment of the third arbitrator within a period of
            seven (7) days from the date of appointment of the second
            arbitrator, then upon the application of either the Landlord or the
            Tenant, the third arbitrator shall be appointed by a Judge of the
            Supreme Court in accordance with the procedure set out in the
            Commercial Arbitration Act, S.B.C. 1986, c.3, as amended from time
            to time, or such similar statute then in force in the province in
            which the Building is located. The third arbitrator shall chair the
            arbitration. The determination made by 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. The Tenant shall pay the
            costs of the arbitration and the arbitrator(s). The provisions of
            this section shall be deemed to be a submission to arbitration
            within the provisions of the replacement or re-enactment thereof,
            provided that any limitation on the remuneration of the arbitrators
            imposed by such legislation shall not be applicable."

                  (v) Article 18.3, Tenant Improvement Allowance, shall be added
            to the Lease as follows:

<PAGE>

            "The Landlord agrees to reimburse the Tenant, as a tenant
            improvement allowance, up to FIVE Dollars FIFTY Cents ($5.50) (the
            "Tenant Improvement Allowance") for the actual costs of the initial
            Leasehold Improvements paid by the Tenant upon receipt by the
            Landlord of complete "As-Built" drawings representing Leasehold
            Improvements installed, an engineer approved air balance report and
            evidence satisfactory to the Landlord that all contractors, workmen,
            material and service suppliers and all other persons having claims
            against the Tenant for payment of work done or material or service
            supplied in connection with the Tenant's Leasehold Improvements have
            been paid in full. The Tenant Improvement Allowance is for the
            purpose of offsetting all or part of the Tenant's expenditure for
            initial Leasehold Improvements. The Tenant Improvement Allowance
            shall not be payable by the Landlord unless the Tenant has completed
            the installation of Leasehold Improvements in accordance with
            drawings and specifications approved by the Landlord and has
            conducted its business from the majority of the Leased Premises
            continuously during normal business hours for a period equal to the
            greater of (i) one month or (ii) the minimum statutory period after
            completion of the Leasehold Improvements for the registration of
            construction liens plus one day. It is a condition precedent to the
            Landlord's obligation to pay the Tenant that a claim for the Tenant
            Improvement Allowance be made to, and the said satisfactory evidence
            is received by, the Landlord before the expiry of the first year of
            the Term. The Landlord shall have the right but not an obligation,
            to pay any contractor, workmen, material and service supplier and
            all other persons who have performed work or supplied material or
            service in connection with the Leasehold Improvements if the Tenant
            has failed to do so, and the Tenant shall pay the Landlord on demand
            the amount the Landlord has so paid, unless such payment is made by
            the Landlord prior to the disbursing to the Tenant of the Tenant
            Improvement Allowance in which case the amount of such payment shall
            be deducted from the Tenant Improvement Allowance.

      2) The Landlord and the Tenant hereby confirm each to the other the
several covenants and agreements in the Lease as amended by this Amendment to
Lease Agreement.

      3) This Amendment to Lease Agreement and everything herein contained shall
enure to the benefit of and be binding upon the respective heirs, executors,
administrators, successors, assigns and other legal representatives, as the case
may be, of each of the parties hereto, and every reference herein to any party
hereto shall include the heirs, executors, administrators, successors, assigns
and other legal representatives of such party, and where there is more than one
tenant or there is a male or female party, the provisions hereof shall be read
with all grammatical changes thereby rendered necessary and all covenants shall
be deemed joint and several.

Agreement. I/We have authority to bind the corporation.
