Unitholders who held their Trust Units outside of a Deferred Plan, through a broker or other intermediary and received cash distributions during the period, will receive "T3 Supplementary" slips directly from their broker or intermediary, not from the transfer agent or the Trust.

Registered Unitholders of Trust Units who received cash distributions during the period from the transfer agent, Computershare Trust Company of Canada, (and not from a broker or intermediary), will receive "T3 Supplementary" slips directly from Computershare Trust Company of Canada. While Computershare Trust Company of Canada will strive to issue these information slips as soon as possible, the deadline for mailing all T3 Supplementary Information slips as required by Canada Revenue Agency is March 31, 2011.

Tax upon the disposition of Trust Units:

The portion of the distributions deemed a return of capital will reduce the Unitholder's adjusted cost base ("ACB") of their units. The ACB of the units is required in the calculation of a capital gain or capital loss (assuming the units are capital property of the Unitholder) upon the disposition or deemed disposition of the Trust units. Unitholders should maintain a record of all distributions that are classified as partially or entirely as a return of capital while holding ARC Energy Trust units. For investors in the $10.00 per unit initial public offering in July 1996, the ACB of units still held as at December 31, 2010, is $2.92 per unit taking into account the return of capital of $6.90 in 1996 through to 2009 and $0.18 in 2010.
