Pengrowth Energy Trust Announces Reinstatement of At-The-Market Equity Financing Program

CALGARY, ALBERTA, Jul 13 (MARKET WIRE) --
Pengrowth Corporation, administrator of Pengrowth Energy Trust
(collectively, "Pengrowth") (TSX: PGF.UN) (NYSE: PGH), today announced
that Pengrowth has entered into an agreement to reinstate the equity
distribution agreement with SG Americas Securities, LLC and FirstEnergy
Capital Corp. (collectively, the "Underwriters") dated December 14, 2007
(the "Agreement") which will permit Pengrowth to distribute up to
25,000,000 trust units from time to time through the Underwriters, as our
agents. To date, no trust units have been distributed by Pengrowth
pursuant to the Agreement.

Sales of trust units, if any, pursuant to the Agreement will be made in
transactions that are deemed to be "at-the-market distributions",
including sales made directly on the New York Stock Exchange (NYSE) or
the Toronto Stock Exchange (TSX). The trust units will be distributed at
market prices prevailing at the time of sale and, as a result, prices may
vary between purchasers and during the period of distribution. The net
proceeds of any given distribution of trust units will be used for
general business purposes. The volume and timing of sales, if any, will
be at Pengrowth's discretion.

The distribution of the trust units pursuant to the Agreement has been
qualified by the filing of a Prospectus Supplement dated July 10, 2009 to
Pengrowth's Short Form Base Shelf Prospectus dated May 5, 2009 with the
securities regulatory authorities in Canada, and by the filing of a
Prospectus Supplement dated July 10, 2009 to Pengrowth's Form F-10
Registration Statement dated May 5, 2009 filed with the United States
Securities and Exchange Commission. The Base Shelf Prospectus and
Prospectus Supplement are available on SEDAR and the Form F-10
Registration Statement and the Prospectus Supplement are available on
EDGAR or, alternatively, can be obtained by contacting Pengrowth Investor
Relations by email at: investorrelations@pengrowth.com or by telephone

This news release shall not constitute an offer to sell or the
solicitation of an offer to buy trust units, nor shall there be any sale
of the trust units in any jurisdiction in which such offer, solicitation
or sale would be unlawful prior to registration or qualification under
the securities laws of such jurisdiction.
