CALGARY, ALBERTA--(Marketwire - Feb. 11, 2011) - Peyto Exploration & Development Corp. ("Peyto") (TSX:PEY) is pleased to announce the 2010 tax information for unitholders of Peyto Energy Trust resident in Canada.

For purposes of the Income Tax Act (Canada), Peyto Energy Trust (the "Trust") was a mutual fund trust. Each year, an income tax return is filed by the Trust with taxable income allocated to and taxable in the hands of the unitholders. Cash distributions paid by the Trust are comprised of a return on capital portion (taxable income) and a return of capital (tax deferred) portion. The return on capital (taxable) portion is calculated and reported on Peyto's T3 return and allocated to each unitholder who received distributions in that taxation year on T3 Supplementary forms, which are mailed to unitholders before March 31 of each year. Registered unitholders will receive a T3 Supplementary form directly from the transfer agent, Valiant Trust Company. Beneficial unitholders will receive a T3 Supplementary form from their broker or other intermediary. The T3 slip will report only the taxable income component. The return of capital (tax deferred) portion reduces the unitholders' cost base of the units. For cash distributions received or receivable by a Canadian resident, outside of a registered pension or retirement plan, tax free savings account or registered education savings plan in the 2010 taxation year, the split is 80 percent return on capital (taxable) and 20 percent return of capital (tax deferred).
