Enerplus and Focus announces merger

Enerplus Resources and Focus Energy have entered into an agreement that provides for the strategic combination of Enerplus and Focus. These two well-respected trusts have combined to create a better, stronger, technically focused organization with exciting prospects for the future.

Under the terms of the agreement, Focus unitholders will receive 0.425 of an Enerplus trust unit for each Focus trust unit. Focus unitholders will receive a value of $17.38 per Focus unit based on the closing price
of Enerplus trust units on the Toronto Stock Exchange as at November 30, 2007 which represents a premium of approximately 3 percent compared to the 10 day weighted average price of Focus and Enerplus trust units on the TSX.

On completion of the combination, Enerplus unitholders will own approximately 79 percent and Focus unitholders will own approximately 21 percent of the combined trust. This transaction is expected to be tax-deferred for both Canadian and U.S. resident Focus unitholders although they may elect to participate in the transaction on a taxable basis for Canadian federal income tax purposes. The combined trust will carry on business as Enerplus and continue to be listed on both the TSX and the New York Stock Exchange.
