Trizec Properties, Inc. and Trizec Canada Inc. Agree to be Acquired by Brookfield Properties and Blackstone.

CHICAGO & TORONTO -- Trizec Properties, Inc. (NYSE:TRZ) and Trizec Canada Inc. (TSX:TZC) today announced that they have entered into a definitive merger and arrangement agreement with Brookfield Properties Corporation for Brookfield to acquire both Trizec Properties and Trizec Canada in a transaction valued at US $8.9 billion. Brookfield is joined in this acquisition by The Blackstone Group.

Under the terms of the merger and arrangement agreement, Brookfield will acquire all outstanding shares of common stock of Trizec Properties that are not owned by Trizec Canada for US $29.01 per share in cash and will acquire all outstanding subordinate voting shares ("SVS") and multiple voting shares of Trizec Canada for US $30.97 (Cdn $34.09) per share in cash. The additional US $1.96 cash consideration per Trizec Canada share reflects the value of Trizec Canada's net assets other than its approximate 38 percent interest in Trizec Properties. Holders of Trizec Canada shares may be given the option to receive a portion of their consideration in the form of preferred shares of Brookfield Properties. Holders of common units in Trizec Holdings Operating LLC, a subsidiary of Trizec Properties, will have the right to receive US $29.01 per common unit in cash, or to receive a common or preferred unit in the surviving limited liability company subsidiary.

The cash consideration for the Trizec Properties common stock represents an 18 percent premium over the June 2, 2006 closing price of Trizec Properties common stock on the NYSE of US $24.60 and a 24 percent premium over the 10-day average closing price through June 2, 2006 for Trizec Properties on the NYSE. The cash consideration for the Trizec Canada SVS represents a 30 percent premium over the closing price of Trizec Canada's SVS on the TSX on June 2, 2006 of Cdn $26.19 (US $23.79) and a 35 percent premium over the 10-day average closing price for Trizec Canada on the TSX.

The boards of directors of Trizec Properties and Trizec Canada have separately approved the merger and arrangement agreement and have recommended the approval of the transaction by their respective stockholders. It is expected that the closing of the transaction will occur during the third or fourth quarter of 2006 and is contingent upon customary closing conditions and the approval of the stockholders of both companies at special meetings to be held on dates to be announced. Both Trizec Properties and Trizec Canada expect to continue to pay regular quarterly dividends in accordance with their past practice, and stockholders will receive a pro rata payment for any partial dividend period until closing of the transaction. The transaction is not contingent on receipt of financing by Brookfield.

"I am extremely proud of the fact that since the acquisition of Trizec in 1994, our management team has created one of the leading property companies in North America," said Peter Munk, Chairman of both Trizec Properties and Trizec Canada. "In the last three years, Trizec Properties stockholders have enjoyed an extraordinary return of 185 percent. Last year alone, Trizec Properties delivered a total return of 26 percent to stockholders, more than double the industry average. This transaction delivers to all Trizec Properties and Trizec Canada stockholders the full value created over this period."

Tim Callahan, Trizec Properties' President & Chief Executive Officer commented, "Since launching as a public REIT, Trizec Properties has successfully created one of the premier national office companies in the country with 40 million square feet of high-quality office space along with an outstanding, dedicated and experienced organization. During this timeframe, we have repositioned Trizec's real estate portfolio with a $5.2 billion acquisition and disposition program. We have also strengthened Trizec's balance sheet and enhanced the company's operating platform, allowing the recent purchase of the largest portfolio in Trizec's history." Mr. Callahan added, "Even though Trizec has made great strides and has delivered one of the best total returns to stockholders for office REITs during the past three years, the company continues to be undervalued in the public markets. In recognizing the underlying value of the company's office portfolio, and especially, its operating platform, the transaction announced today accomplishes Trizec's ultimate objective as a public company, which is to maximize stockholder value. While I am especially pleased with the significant accomplishments this company has made over the years, my only regret is that once this transaction closes, I will not have the opportunity to be part of the organization as it continues to evolve."

Brookfield has entered into definitive support agreements with Trizec Canada regarding its interest in Trizec Properties and with P.M. Capital Inc., a corporation wholly owned by Peter Munk, regarding its interest in Trizec Canada. The support agreements provide that Trizec Canada and P.M. Capital will vote their shares in favor of the transaction.

Hogan & Hartson LLP acted as legal advisor to Trizec Properties. RBC Capital Markets acted as financial advisor to and provided a fairness opinion for Trizec Canada and Davies Ward Phillips & Vineberg LLP acted as legal advisor.
