HISTORICAL PERFORMANCE

Total Return to Unitholders

Calculated using unit prices at December 31 plus or minus capital appreciation or depreciation and the total cash distributions paid during the period.

Distributions to U.S. unitholders are converted to U.S. dollars on the applicable payment date. Amounts shown are prior to any amounts deducted for Canadian withholding tax. As Enerplus became listed on the NYSE in November of 2000, returns and cash distributions paid in U.S. dollars are reflected for all subsequent years only.
