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.
