BIOMED REALTY TRUST REPORTS
FIRST QUARTER 2008 FINANCIAL RESULTS

SAN DIEGO, Calif. — April 30, 2008 — BioMed Realty Trust, Inc. (NYSE: BMR), a real estate investment trust focused on providing real estate to the life science industry, today announced financial results for the first quarter ended March 31, 2008.

Highlights:

• Funds from operations (FFO) for the quarter were $31.3 million, or $0.46 per diluted share

• Increased quarterly common stock dividend by 8.1% to $0.335 per share, equivalent to an annualized common stock dividend of $1.34 per share

• Executed a long-term lease for 90,000 square feet with Revance Therapeutics, Inc. at the Pacific Research Center, marking the company’s first life science tenant at the Pacific Research Center, located in the San Francisco market

• Acquired the 500 Fairview Avenue property, an approximately 22,000 square foot building in Seattle, Washington that is fully leased to the State of Washington and targeted for future redevelopment as laboratory/office space

• Entered into a $245.0 million secured construction loan facility through our joint venture with Prudential Real Estate Investors, at an initial interest rate of reserve adjusted LIBOR plus a spread of 150 basis points, to fund the remaining anticipated cost to complete construction at our 650 East Kendall Street property

• Extended the term of the secured acquisition and interim loan facility of our joint venture with Prudential Real Estate Investors to April 3, 2009

“We delivered yet another strong quarter of financial results in the first quarter. Our operating performance was solid and we are making good progress in our development and redevelopment pipeline, and steady progress in our leasing program. We remain cautiously optimistic that the limited correlation between the currently volatile credit markets and the long-term demand for research in the life science industry will allow us to continue our stable growth through 2008 and beyond,” commented Alan D. Gold, President and Chief Executive Officer of BioMed Realty Trust.

First Quarter 2008 Financial Results

Rental revenues for the quarter were $50.3 million, representing a 6.0% increase versus the first quarter of 2007. Same property net operating income increased 4.9% on a cash basis for the first quarter of 2008 compared to the first quarter of 2007.

Total revenues for the quarter were $67.4 million, compared to $68.8 million in the first quarter of 2007. Total revenues, net income and FFO for the first quarter of 2007 included the effect of a $4.8 million lease termination fee (or approximately $0.07 per diluted share) related to the company’s Elliott Avenue property. Net income available to common stockholders for the quarter was $12.6 million, or $0.19 per diluted share, compared to $16.0 million, or $0.25 per diluted share, in the first quarter of 2007.

FFO during the quarter was to $31.3 million, compared to $34.2 million in the comparable period in 2007. FFO per diluted share was $0.46 for the first quarter of 2008 versus $0.50 in the first quarter of 2007.

FFO is a supplemental non-GAAP financial measure used in the real estate industry to measure and compare the operating performance of real estate companies. A complete reconciliation containing adjustments from GAAP net income available to common stockholders to FFO and a definition of FFO are included at the end of this release.

Financing Activity

On February 13, 2008, the company’s joint venture with Prudential Real Estate Investors entered into a secured construction loan facility with Wachovia Bank, National Association and other lenders to provide borrowings of up to approximately $245.0 million in connection with the construction of 650 East Kendall Street, an approximately 280,000 square foot Class A laboratory/office building located in East Cambridge, Massachusetts. Proceeds from the secured construction loan were used in part to repay a portion of the joint venture’s secured acquisition and interim loan facility and will also be used to fund the balance of the anticipated cost to complete construction of the project. The secured construction loan initially bears interest at a floating rate equal to reserve adjusted LIBOR plus a spread of 150 basis points. The secured construction loan has a maturity date of August 13, 2010 and is secured by the 650 East Kendall Street property and related collateral.

On February 19, 2008, the company’s joint venture with Prudential Real Estate Investors extended the term of its secured acquisition and interim loan facility by one year to April 3, 2009, with no additional changes to the pricing or terms of the facility.

As of March 31, 2008, the company’s consolidated debt included fixed-rate mortgage indebtedness with an aggregate outstanding principal amount of $377.7 million, including $10.3 million of debt premium, and a weighted-average effective interest rate of 5.5% at quarter-end; the company’s $250 million secured term loan, with a weighted-average effective interest rate of 4.8% at quarter-end; $175 million aggregate principal amount of 4.50% exchangeable senior notes due 2026; $310.7 million in outstanding borrowings under the company’s $600 million unsecured revolving line of credit, with a weighted-average effective interest rate of 4.1% at quarter-end; and $457.6 million in outstanding borrowings under the company’s acquisition and construction loan secured by the Center for Life Science | Boston property, with a weighted-average effective interest rate of 4.2% at quarter-end. The company’s debt to total capitalization ratio was 45.5% at March 31, 2008.

After the quarter’s end, on April 22, 2008, the company completed the sale of 6,129,000 shares of common stock at $25.50 per share, resulting in gross offering proceeds of approximately $156.3 million.

“The ability of our joint venture with Prudential Real Estate Investors to secure $245.0 million at reserve adjusted LIBOR plus a 150 basis point spread is a testament to the strength of the joint venture, our proven ability to execute on our business model and the world-class quality of the assets we are developing through the joint venture. Coupling this financing with the extension of our joint venture’s existing facility to April 2009 and the raising of approximately $156.3 million in gross proceeds in our April 2008 follow-on public offering, we were able to further enhance what was already a very solid financial position,” commented Kent Griffin, Chief Financial Officer of BioMed Realty Trust.

Portfolio Update

During the quarter, the company acquired the 500 Fairview Avenue property, an approximately 22,000 square foot building which is fully leased to the State of Washington and targeted for future redevelopment as laboratory/office space, located adjacent to the company’s 530 Fairview Avenue property in Seattle, Washington.

As of March 31, 2008, BioMed Realty Trust owned or had interests in 112 buildings, located predominantly in the major U.S. life science markets of Boston, San Diego, San Francisco,

FUNDS FROM OPERATIONS
(In thousands, except share and per share data)
(Unaudited)

     The following table provides the calculation of our FFO and a reconciliation to net income available to common stockholders (in thousands, except per share amounts):

	For the Three Months
	Ended March 31,
	2008			2007
Net income available to common stockholders	$	12,567		$	16,049
Adjustments:
Minority interests in operating partnership		589			715
Depreciation and amortization — unconsolidated partnerships		451			20
Depreciation and amortization — consolidated entities-discontinued operations		—			137
Depreciation and amortization — consolidated entities-continuing operations		17,687			17,254
Depreciation and amortization — allocable to minority interest of consolidated joint ventures		(8	)		—
Funds from operations available to common shares and partnership and LTIP units	$	31,286		$	34,175
Funds from operations per share — diluted	$	0.46		$	0.50
Weighted-average common shares outstanding — diluted		68,429,903			68,231,124

We present funds from operations, or FFO, available to common shares and partnership and LTIP units because we consider it an important supplemental measure of our operating performance and believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO when reporting their results. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income. We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT, in its March 1995 White Paper (as amended in November 1999 and April 2002). As defined by NAREIT, FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property, plus real estate related depreciation and amortization (excluding amortization of loan origination costs) and after adjustments for unconsolidated partnerships and joint ventures. Our computation may differ from the methodology for calculating FFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO does not represent amounts available for management’s discretionary use because of needed capital replacement or expansion, debt service obligations, or other commitments and uncertainties. FFO should not be considered as an alternative to net income (loss) (computed in accordance with GAAP) as an indicator of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions.
