Distribution Reinvestment (DRIP) and Optional Trust Unit Purchase Plan

Unitholders may elect to participate in a cash distribution reinvestment plan that will automatically reinvest all or part of the distributions from ARC Energy Trust in additional trust units. An optional cash investment program is also available to allow cash payments of up to $3,000 per distribution. Both plans facilitate investment in additional trust units at a five per cent discount to prevailing market prices with no brokerage commission or Trust fees.
