DALLAS, Texas, March 21, 2011 - Tidelands Royalty Trust “B” (OTC BB: TIRTZ.OB) (“Tidelands”) oday declared a quarterly cash distribution to the holders of its units of beneficial interest of $0.225347 per unit, payable on April 14, 2011, to unitholders of record on March 31, 2011.

The distribution this quarter decreased to $0.225347 per unit from $0.366288 per unit last quarter. Royalties received this quarter as compared to the last quarter are down primarily due to a 30% decrease in revenue from the three fields in the West Cameron Area. The volume of oil and natural gas produced and included in this report was down and there was a slight reduction in the price realized for natural gas.

Tidelands’ distributions to unitholders are determined by royalties received up to the date the distribution amount is declared. In general, Tidelands receives royalties two months after oil production and three months after natural gas production.
