All dollar references are in U.S. dollars unless noted otherwise.

NEW YORK -- Brookfield Properties Corporation (BPO: NYSE, TSX) today announced that net income for the three months ended March 31, 2008 was $23 million or $0.06 per diluted share, compared to $53 million or $0.13 per diluted share during the same period in 2007. The prior period included a net gain of $34 million or $0.08 per diluted share on the sale of three non-core properties in Toronto and Ottawa.

Strong commercial property results, largely offsetting slow residential operations, resulted in funds from operations ("FFO") of $126 million or $0.32 per diluted share for the three months ended March 31, 2008 compared with $129 million or $0.32 per diluted share during the same period in 2007.

Commercial property net operating income for the first quarter of 2008 was $349 million, up 11.5% from $313 million during the first quarter of 2007. Residential operations contributed $18 million of net operating income, compared with $42 million in the same period in 2007.

During the first quarter, Brookfield Properties leased over one million square feet of space at an average net rent of $32.71 per square foot, which represents a 42% improvement versus the average in-place net rent at the beginning of the quarter of $23.11 per square foot. The company's portfolio-wide occupancy rate finished the quarter at 95.4%.

The fundamentals of the Western Canadian residential operations remain strong despite a slow quarter as a result of higher-than-normal housing inventory levels. With oil and natural gas prices hitting new highs, Brookfield Properties expects the residential division to continue to increase its sales pace which has improved each month since the beginning of the year.

OUTLOOK

"With a strong tenant base and conservative lease expiry profile, Brookfield Properties is well-positioned in the face of softening U.S. economic conditions," stated Ric Clark, President & CEO of Brookfield Properties Corp.

Net Operating Income and FFO

This press release and accompanying financial information make reference to net operating income and funds from operations on a total and per share basis. Net operating income is defined as income from property operations after operating expenses have been deducted, but prior to deducting financing, administrative and income tax expenses. Brookfield Properties defines FFO as net income prior to extraordinary items, one-time transaction costs, income taxes, depreciation and amortization, and certain other non-cash items. The company uses net operating income and FFO to assess its operating results. Net operating income is important in assessing operating performance and FFO is a relevant measure to analyze real estate, as commercial properties generally appreciate rather than depreciate. The company provides the components of net operating income and a full reconciliation from net income to FFO with the financial information accompanying this press release. The company reconciles FFO to net income as opposed to cash flow from operating activities as it believes net income is the most comparable measure. Net operating income and FFO are both non-GAAP measures which do not have any standard meaning prescribed by GAAP and therefore may not be comparable to similar measures presented by other companies.
