provided for in Section 2.

SECTION 5      PAYMENTS UNDER THIS AGREEMENT:  Any payment to be made by the
Corporation pursuant to the terms of this Agreement shall be made by the
Corporation in cash in a lump sum within five business days of the giving of
notice by the Executive pursuant to Section 3, or within five business days of
the dismissal from the Executive's employment as referred to in Section 4, as
the case may be. Any payment to be made under Section 2 or 4 shall be
calculated, in the case of Section 2, at the date of giving notice pursuant to
Section 3 and, in the case of Section 4, at the date of dismissal.
Notwithstanding the foregoing provisions of this Section 5, at the option of
the Executive a payment, or any part thereof as shall be specified by the
Executive, to be made to the Executive shall be deferred to such date or dates
as shall be designated in writing by the Executive. Any payment so deferred
shall bear simple interest at the rate of 6% per annum calculated from the date
payment of the amount otherwise should have been made until the date of payment
in full. The Corporation shall list the items making up a payment calculated
as provided for in Section 2 and shall support the calculation of such amount.

SECTION 6      PAYMENTS IN LIEU OF ALL OTHER DAMAGE CLAIMS ETC.:  All payments
provided for herein shall be in lieu of all other notice or damage claims as
regards dismissal or termination of the Executive's employment with the
Corporation or any subsidiary of the Corporation after a Change in Control and
on or before the Expiry Date. The arrangements provided for herein shall not
be considered in any judicial determination of appropriate damages at common
law for dismissal without cause, other than as provided for in this Agreement.
At the request of either party, the parties shall exchange mutual signed
releases of liability conforming to the substantive provisions of this
Agreement.

SECTION 7      AGREEMENT SUPPLEMENTAL:  This Agreement shall be supplemental to
any other contract of employment or otherwise, whether written or oral, that
exists between the Corporation or any subsidiary of the Corporation and the
Executive, except insofar as any such contract relates to the termination of
the employment relationship between the Corporation or any Subsidiary of the
Corporation and the Executive, in which case this Agreement shall supersede the
termination provisions of any such other contract of employment or otherwise.

SECTION 8      BENEFIT PLANS:  In the event that the Executive is entitled to a
payment pursuant to Section 2 or 4, the Executive shall be entitled to have all
Benefit Plans as constituted at the date of the giving of notice by the
Executive pursuant to Section 3, or the dismissal from the Executive's
employment, as the case may be, continued for a period of 24 months after the
date of the giving of notice by the Executive pursuant to Section 3, or the
dismissal from the Executive's employment, as the case may be, or for any
longer period available under any Benefit Plans when coverage is provided from
a source other than the Corporation. Notwithstanding the foregoing provisions
of this Section 8, at the option of the Executive the cost to the Corporation
of such Benefit Plans, or any part of the benefits under any such Benefit Plans
as shall be specified by the Executive, shall be converted to a lump sum amount
and shall be paid to the Executive immediately or shall be deferred to such
date or dates as shall be designated in writing by the Executive. Any payment
so deferred shall bear simple interest at the rate of 6% per annum calculated
from the date payment of the amount otherwise should have been made until the
date of payment in full.

SECTION 9      STOCK OPTION AND STOCK PURCHASE PLANS:  If the Executive is
entitled to a payment pursuant to Section 2 or 4, the term during which any
stock option granted to the Executive by the Corporation or any subsidiary of
the Corporation may be exercised shall be extended to the later of the expiry
date of the option or 12 months after the date of the giving of notice by the
Executive pursuant to Section 3, or the dismissal from the Executive's
employment as referred to in Section 4, as the case may be; provided that the
maximum term of any such option shall not exceed six years from the date of
grant of the option or such longer period as shall be permitted under the terms
of the Corporation's stock option plan. In addition, in such event any
provisions of the stock option or the stock purchase plan restricting the
number of shares which may be purchased before a particular date shall be
waived and the options shall be fully vested immediately. If the Executive is
entitled to a payment pursuant to Section 2 or 4, all shares owned by the
Executive and held in any stock purchase plan shall immediately be released to
the Executive, subject to the Executive making any payments required under the
plan. The terms of any stock option plan, stock purchase plan or agreement
therefor shall be deemed amended to reflect the provisions of this Section 9.

SECTION 10     DESIGNATION OF BENEFICIARY: If the Executive dies prior to
satisfaction of all of the Corporation's obligations under this Agreement, any
remaining amounts payable to the Executive by the Corporation shall be paid to
the person or persons (a "Beneficiary") previously designated by the Executive
to the Corporation for such purposes. Any such designation of a Beneficiary
shall be made in writing, signed by the Executive and dated and filed with the
Secretary of the Corporation. In the event that no such designation is made,
all such remaining amounts shall be paid by the Corporation to the Estate of
the Executive. If the Executive has exercised the option pursuant to Section 5
or 8 to defer a payment, or any part thereof, to be made to or for the benefit
of the Executive, the Beneficiary or the Executor of the Estate, as the case
may be, shall have the further option to require payment in full of any such
remaining amounts to the Beneficiary or the Executor, as the case may be, by
giving notice to that effect to the Corporation.

SECTION 11     ASSIGNMENT AND ASSUMPTION:  This Agreement automatically shall
be assigned by the Corporation to any successor corporation of the Corporation
and shall be binding upon such successor corporation. For the purposes of this
Section 11, "successor corporation" shall include any person referred to in
Subsection 1(b)(ii), (iii) or (iv). The Corporation shall ensure that the
successor corporation shall continue the provisions of this Agreement as if it
were the original party in place of the Corporation; provided however that the
Corporation shall not thereby be relieved of any obligation to the Executive
pursuant to this Agreement. In the event of a transaction or series of
transactions as described in Subsection 1(b)(ii), (iii) or (iv), appropriate
arrangements shall be made by the Corporation for the successor corporation to
honour this Agreement as if the Executive had exercised his maximum rights
hereunder as of the effective date of such transaction.

SECTION 12     FURTHER ASSURANCES:  Each of the parties hereto agrees to do and
execute or cause to be made, done or executed all such further and other
things, acts, deeds, documents, assignments and assurances as may be necessary
or reasonably required to carry out the intent and purpose of this Agreement
fully and effectually. Without limiting the generality of the foregoing, the
Corporation shall take all reasonable steps in order to structure the payment
or payments provided for in this Agreement in the manner most advantageous to
the Executive with respect to the provisions of the Income Tax Act (Canada),
the Internal Revenue Code (United States of America) or any similar legislation
in place in any other jurisdiction of the Executive's residence.

Change in Control of the Corporation, and following an actual Change in Control
of the Corporation, the Corporation in either case shall enter into a review of
the terms of this Agreement and shall implement any amendments hereto which are
agreed to by both parties.

SECTION 14     RE-TRANSFER: If, within 12 months prior to the date of the
Triggering Event, or the date of dismissal without cause, as the case may be,
the Executive was transferred by the Corporation or the Subsidiary to his then
place of residence and if the Executive has been resident in such location for
less than 24 months at the time that he becomes entitled to a payment pursuant
to Section 2 or 4, if the Executive exercises his rights under this Section 14
at the time of the giving of notice by the Executive pursuant to Section 3, or
upon giving notice to the Corporation within 30 days of dismissal from the
Executive's employment as referred to in Section 4, as the case may be, the
Corporation shall pay the direct moving expenses of moving the Executive and
his immediate family and their household effects to his immediately preceding
place of residence offset by any such costs paid by any new employer.

SECTION 15     OUTPLACEMENT SERVICES:  If the Executive is entitled to receive
a payment pursuant to Section 2 or 4, the Corporation shall pay the reasonable
costs (to a maximum of 10% of the annual base salary of the Executive as used
for the calculation of such payment) of the services for the Executive of a
suitable outplacement counselling service selected by the Corporation.
Notwithstanding the foregoing provisions of this Section 15, at the option of
the Executive the cost to the Corporation of such outplacement services shall
be converted to a lump sum amount and shall be paid to the Executive
immediately.

permits, the masculine gender includes the feminine gender.

the dismissal from the Executive's employment as referred to in Section 4, as
the case may be. Any payment to be made under Section 2 or 4 shall be

the amount otherwise should have been made until the date of payment in full.
The Corporation shall list the items making up a payment calculated as provided

SECTION 6     PAYMENTS IN LIEU OF ALL OTHER DAMAGE CLAIMS ETC.: All payments
provided for herein shall be in lieu of all other notice or damage claims as
regards dismissal or termination of the Executive's employment with the
Corporation or any subsidiary of the Corporation after a Change in Control and
on or before the Expiry Date. The arrangements provided for herein shall not be
considered in any judicial determination of appropriate damages at common law
for dismissal without cause, other than as provided for in this Agreement. At
the request of either party, the parties shall exchange mutual signed releases
of liability conforming to the substantive provisions of this Agreement.

SECTION 7     AGREEMENT SUPPLEMENTAL: This Agreement shall be supplemental to
any other contract of employment or otherwise, whether written or oral, that
exists between the Corporation or any subsidiary of the Corporation and the
Executive, except insofar as any such contract relates to the termination of the
employment relationship between the Corporation or any Subsidiary of the
Corporation and the Executive, in which case this Agreement shall supersede the
termination provisions of any such other contract of employment or otherwise.

Executive pursuant to Section 3, or the dismissal from the Executive's
employment, as the case may be, continued for a period of 24 months after the
date of the giving of notice by the Executive pursuant to Section 3, or the
dismissal from the Executive's employment, as the case may be, or for any longer
period available under any Benefit Plans when coverage is provided from a source
other than the Corporation. Notwithstanding the foregoing provisions of this
Section 8, at the option of the Executive the cost to the Corporation of such
Benefit Plans, or any part of the benefits under any such Benefit Plans as shall
be specified by the Executive, shall be converted to a lump sum amount and shall
be paid to the Executive immediately or shall be deferred to such date or dates
as shall be designated in writing by the Executive. Any payment so deferred
shall bear simple interest at the rate of 6% per annum calculated from the date
payment of the amount otherwise should have been made until the date of payment
in full.

the Corporation may be exercised shall be extended to the later of the expiry
date of the option or 12 months after the date of the giving of notice by the
Executive pursuant to Section 3, or the dismissal from the Executive's
employment as referred to in Section 4, as the case may be; provided that the
maximum term of any such option shall not exceed six years from the date of
grant of the option or such longer period as shall be permitted under the terms
of the Corporation's stock option plan. In addition, in such event any
provisions of the stock option or the stock purchase plan restricting the number
of shares which may be purchased before a particular date shall be waived and
the options shall be fully vested immediately. If the Executive is entitled to a
payment pursuant to Section 2 or 4, all shares owned by the Executive and held
in any stock purchase plan shall immediately be released to the Executive,
subject to the Executive making any payments required under the plan. The terms
of any stock option plan, stock purchase plan or agreement therefor shall be
deemed amended to reflect the provisions of this Section 9.

SECTION 10    DESIGNATION OF BENEFICIARY: If the Executive dies prior to
satisfaction of all of the Corporation's obligations under this Agreement, any
remaining amounts payable to the Executive by the Corporation shall be paid to
the person or persons (a "Beneficiary") previously designated by the Executive
to the Corporation for such purposes. Any such designation of a Beneficiary
shall be made in writing, signed by the Executive and dated and filed with the
Secretary of the Corporation. In the event that no such designation is made, all
such remaining amounts shall be paid by the Corporation to the Estate of the
Executive. If the Executive has exercised the option pursuant to Section 5 or 8
to defer a payment, or any part thereof, to be made to or for the benefit of the
Executive, the Beneficiary or the Executor of the Estate, as the case may be,
shall have the further option to require payment in full of any such remaining
amounts to the Beneficiary or the Executor, as the case may be, by giving notice
to that effect to the Corporation.

SECTION 11    ASSIGNMENT AND ASSUMPTION: This Agreement automatically shall be
assigned by the Corporation to any successor corporation of the Corporation and
shall be binding upon such successor corporation. For the purposes of this
Section 11, "successor corporation" shall include any person referred to in
Subsection 1(b)(ii), (iii) or (iv). The Corporation shall ensure that the
successor corporation shall continue the provisions of this Agreement as if it
were the original party in place of the Corporation; provided however that the
Corporation shall not thereby be relieved of any obligation to the Executive
pursuant to this Agreement. In the event of a transaction or series of
transactions as described in Subsection 1(b)(ii), (iii) or (iv), appropriate
arrangements shall be made by the Corporation for the successor corporation to
honour this Agreement as if the Executive had exercised his maximum rights
hereunder as of the effective date of such transaction.

SECTION 12    FURTHER ASSURANCES: Each of the parties hereto agrees to do and
execute or cause to be made, done or executed all such further and other things,
acts, deeds, documents, assignments and assurances as may be necessary or
reasonably required to carry out the intent and purpose of this Agreement fully
and effectually. Without limiting the generality of the foregoing, the
Corporation shall take all reasonable steps in order to structure the payment or
payments provided for in this Agreement in the manner most advantageous to the
Executive with respect to the provisions of the Income Tax Act (Canada), the
Internal Revenue Code (United States of America) or any similar legislation in
place in any other jurisdiction of the Executive's residence.

Change in Control of the Corporation, and following an actual Change in Control
of the Corporation, the Corporation in either case shall enter into a review of
the terms of this Agreement and shall implement any amendments hereto which are
agreed to by both parties.

SECTION 14    RE-TRANSFER: If, within 12 months prior to the date of the
Triggering Event, or the date of dismissal without cause, as the case may be,
the Executive was transferred by the Corporation or the Subsidiary to his then
place of residence and if the Executive has been resident in such location for
less than 24 months at the time that he becomes entitled to a payment pursuant
to Section 2 or 4, if the Executive exercises his rights under this Section 14
at the time of the giving of notice by the Executive pursuant to Section 3, or
upon giving notice to the Corporation within 30 days of dismissal from the
Executive's employment as referred to in Section 4, as the case may be, the
Corporation shall pay the direct moving expenses of moving the Executive and his
immediate family and their household effects to his immediately preceding place
of residence offset by any such costs paid by any new employer.

SECTION 15    OUTPLACEMENT SERVICES: If the Executive is entitled to receive a
payment pursuant to Section 2 or 4, the Corporation shall pay the reasonable
costs (to a maximum of 10% of the annual base salary of the Executive as used
for the calculation of such payment) of the services for the Executive of a
suitable outplacement counselling service selected by the Corporation.
Notwithstanding the foregoing provisions of this Section 15, at the option of
the Executive the cost to the Corporation of such outplacement services shall be
converted to a lump sum amount and shall be paid to the Executive immediately.
