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.
