	    Enerplus is a high-yielding equity investment in the oil and natural gas
business. We are one of Canada's oldest and largest independent oil and gas
producers established in 1986. We have built a balanced and diversified
portfolio of producing properties across western Canada and the United States
with a focus on large resource plays that offer predictable production and
repeatable, low-risk development opportunities in conventional oil and gas
production as well as in Canada's oil sands. Enerplus creates value through
development drilling, optimization and acquisitions that enhance the
sustainability of our business over the long-term. Through our discipline of
paying a significant portion of our cash flow to investors each month, we
believe we offer an attractive investment in the oil and gas industry.
