Explanation of Responses:
( 1)  N/A - The distribution equivalent rights accrued on the number of Deferred Share Units ("DSUs") recorded in his account. Each distribution equivalent right is the economic equivalent of one DSU. Upon termination of board service, Common Units representing limited partnership interests may be purchased on the open market on behalf of Mr. Mirosh whereby he would receive Common Units in a number equal to the number of DSUs recorded in his account less any applicable withholdings. Alternatively, Mr. Mirosh may elect to receive the value of his DSU entitlement in cash. The cash payment amount shall be determined by multiplying the number of DSUs recorded in his account by the Fair Market Value of a Common Unit less any applicable withholdings.
( 2)  N/A - the DSUs are fully vested and are redeemable only following Mr. Mirosh's termination of Board service.
( 3)  The distribution amount reflects the number of DSUs added to the director's share unit account as of the record date for the distribution. Pursuant to the Share Unit Plan for Non-Employee Directors (2007), the distribution amount is calculated based on the declared distribution multiplied by the number of share units in the account, divided by the market value of the common units on the payment date for such distribution.
