* The Matching element relates to the Partnership Shares acquired by Deryk King
on 10 April 2006 and on 8 May 2006.

The NAESPP operates as follows

-- Each month the Administrator uses participants' contributions (which are
from 1% to 5% of base salary but may not exceed $10,000 per participant
per year) to purchase shares in the market. These shares are called
'Partnership Shares'. Participants may hold both fractional and whole
Partnership Shares.

-- For every two Partnership Shares the participants still own after two
years, the Company awards one free share. These are called 'Matching
Shares'.

-- Participants may change their monthly savings rate whenever they wish.
However, Directors and others bound by the Company's Securities Dealing
Code (the "Code") may not make such a change during a close period or
when otherwise prohibited from dealing by the Code.

-- The NAESPP is only open to employees of the Company based in Canada and
the United States. No other Directors or PDMRs of the Company are
participants in the NAESPP.
