NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Description of Business

     BioMed Realty Trust, Inc., a Maryland corporation (the “Company”), was incorporated in Maryland on April 30, 2004. On August 11, 2004, the Company commenced operations after completing its initial public offering. The Company operates as a fully integrated, self-administered and self-managed real estate investment trust (“REIT”) focused on acquiring, developing, owning, leasing and managing laboratory and office space for the life science industry principally through its subsidiary, BioMed Realty, L.P., a Maryland limited partnership (the “Operating Partnership”). The Company’s tenants primarily include biotechnology and pharmaceutical companies, scientific research institutions, government agencies and other entities involved in the life science industry. The Company’s properties are generally located in markets with well-established reputations as centers for scientific research, including Boston, San Diego, San Francisco, Seattle, Maryland, Pennsylvania and New York/New Jersey.

2. Basis of Presentation and Summary of Significant Accounting Policies

     The accompanying interim financial statements are unaudited, but have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments and eliminations, consisting of normal recurring adjustments necessary for a fair presentation of the financial statements for these interim periods have been recorded. These financial statements should be read in conjunction with the audited consolidated financial statements and notes therein included in the Company’s annual report on Form 10-K for the year ended December 31, 2007.

Principles of Consolidation

     The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, partnerships and limited liability companies it controls, and variable interest entities for which the Company has determined itself to be the primary beneficiary. All material intercompany transactions and balances have been eliminated. The Company consolidates entities the Company controls and records a minority interest for the portions not owned by the Company. Control is determined, where applicable, by the sufficiency of equity invested and the rights of the equity holders, and by the ownership of a majority of the voting interests, with consideration given to the existence of approval or veto rights granted to the minority shareholder. If the minority shareholder holds substantive participating rights, it overcomes the presumption of control by the majority voting interest holder. In contrast, if the minority shareholder simply holds protective rights (such as consent rights over certain actions), it does not overcome the presumption of control by the majority voting interest holder.

Investments in Partnerships

     The Company evaluates its investments in limited liability companies and partnerships under Financial Accounting Standards Board (“FASB”) Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities (“FIN 46R”), an interpretation of Accounting Research Bulletin No. 51, Consolidated Financial Statements. FIN 46R provides guidance on the identification of entities for which control is achieved through means other than voting rights (“variable interest entities”) and the determination of which business enterprise should consolidate the variable interest entity (the “primary beneficiary”). Generally, FIN 46R applies when either (1) the equity investors (if any) lack one or more of the essential characteristics of a controlling financial interest, (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support or (3) the equity investors have voting rights that are not proportionate to their economic interests and the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest.

     If FIN 46R does not apply, the Company considers Emerging Issues Task Force (“EITF”) Issue No. 04-5, Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights (“EITF 04-5”), which provides guidance in determining whether a general partner controls a limited partnership. EITF 04-5 states that the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. If the criteria in EITF 04-5 are met and the Company is the general partner or the managing member, as applicable, the consolidation of the partnership or limited liability company is required.

     Except for investments that are consolidated in accordance with FIN 46R or EITF 04-5, the Company accounts for investments in entities over which it exercises significant influence, but does not control, under the equity method of accounting. These investments are recorded initially at cost and subsequently adjusted for equity in earnings and cash contributions and distributions. Under the equity method of accounting, the Company’s net equity in the investment is reflected in the consolidated balance sheets and its share of net income or loss is included in the Company’s consolidated statements of income.

     On a periodic basis, management assesses whether there are any indicators that the carrying value of the Company’s investments in unconsolidated partnerships or limited liability companies may be impaired on a more than temporary basis. An investment is impaired only if management’s estimate of the fair-value of the investment is less than the carrying value of the investment on a more than temporary basis. To the extent impairment has occurred, the loss is measured as the excess of the carrying value of the investment over the fair-value of the investment. Management does not believe that the value of any of the Company’s unconsolidated investments in partnerships or limited liability companies was impaired as of June 30, 2008.

Investments in Real Estate

     Investments in real estate, net consists of the following (in thousands):

		June 30, 2008				December 31, 2007
Land		$	334,306			$	313,685
Land under development			83,259				103,743

Accumulated depreciation			(129,221	)			(104,444	)
		$	2,885,704			$	2,805,983

     A portion of the parking spaces at the garage located on the Company’s Center for Life Science | Boston property will be sold to a tenant at a fixed price pursuant to an agreement assumed in connection with the acquisition of the property in November 2006. The carrying value of the garage allocable to the portion that will be sold, approximately $29.0 million, has been recorded in other assets on the consolidated balance sheets as of June 30, 2008. The sale is expected to be completed in the third quarter of 2008.

Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed

     The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of recoverability is based on an estimate of the future undiscounted cash flows (excluding interest charges) expected to result from the long-lived asset’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a long-lived asset, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair-value of the property. The Company is required to make subjective assessments as to whether there are impairments in the values of its investments in long-lived assets. These assessments have a direct impact on the Company’s net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Although the Company’s strategy is to hold its properties over the long-term, if the Company’s strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized to reduce the property to the lower of the carrying amount or fair-value less costs to sell, and such loss could be material. If the Company determines that impairment has occurred, the affected assets must be reduced to their fair-value. As of and through June 30, 2008, no assets have been identified as impaired and no such impairment losses have been recognized.

Deferred Leasing Costs

     Leasing commissions and other direct costs associated with new or renewal lease activity are recorded at cost and amortized on a straight-line basis over the terms of the respective leases, with remaining terms ranging from one month to approximately 16 years as of June 30, 2008. Deferred leasing costs also include the net carrying value of acquired in-place leases and acquired management agreements.

     Deferred leasing costs, net at June 30, 2008 consisted of the following (in thousands):

		Balance at
		June 30,				Accumulated
		2008				Amortization				Net
Acquired in-place leases		$	168,391			$	(81,784	)		$	86,607
Acquired management agreements			12,921				(7,548	)			5,373

		$	201,265			$	(91,885	)		$	109,380

     Deferred leasing costs, net at December 31, 2007 consisted of the following (in thousands):

		Balance at
		December 31,				Accumulated
		2007				Amortization				Net
Acquired in-place leases		$	167,664			$	(71,412	)		$	96,252

		$	196,126			$	(79,635	)		$	116,491

Revenue Recognition

     The Company commences revenue recognition on its leases based on a number of factors. In most cases, revenue recognition under a lease begins when the lessee takes possession of or controls the physical use of the leased asset. Generally, this occurs on the lease commencement date. In determining what constitutes the leased asset, the Company evaluates whether the Company or the lessee is the owner, for accounting purposes, of the tenant improvements. If the Company is the owner, for accounting purposes, of the tenant improvements, then the leased asset is the finished space and revenue recognition begins when the lessee takes possession of the finished space, typically when the improvements are substantially complete. If the Company concludes that it is not the owner, for accounting purposes, of the tenant improvements (the lessee is the owner), then the leased asset is the unimproved space and any tenant improvement allowances funded under the lease are treated as lease incentives which reduce revenue recognized over the term of the lease. In these circumstances, the Company begins revenue recognition when the lessee takes possession of the unimproved space for the lessee to construct improvements. The determination of who is the owner, for accounting purposes, of the tenant improvements determines the nature of the leased asset and when revenue recognition under a lease begins. The Company considers a number of different factors to evaluate whether it or the lessee is the owner of the tenant improvements for accounting purposes. These factors include:

	•		whether the lease stipulates how and on what a tenant improvement allowance may be spent;
	•		whether the tenant or landlord retain legal title to the improvements;
	•		the uniqueness of the improvements;
	•		the expected economic life of the tenant improvements relative to the length of the lease;
	•		the responsible party for construction cost overruns; and
	•		who constructs or directs the construction of the improvements.

     The determination of who owns the tenant improvements, for accounting purposes, is subject to significant judgment. In making that determination, the Company considers all of the above factors. However, no one factor is determinative in reaching a conclusion.

     All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the term of the related lease. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in accrued straight-line rents on the accompanying consolidated balance sheets and contractually due but unpaid rents are included in accounts receivable. Existing leases at acquired properties are reviewed at the time of acquisition to determine if contractual rents are above or below current market rents for the acquired property. An identifiable lease intangible asset or liability is recorded based on the present value (using a discount rate that reflects the risks associated with the acquired leases) of the difference between (1) the contractual amounts to be paid pursuant to the in-place leases and (2) the Company’s estimate of the fair market lease rates for the corresponding

in-place leases at acquisition, measured over a period equal to the remaining non-cancelable term of the leases and any fixed rate renewal periods (based on the Company’s assessment of the likelihood that the renewal periods will be exercised). The capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. The capitalized below-market lease values are amortized as an increase to rental income over the remaining non-cancelable terms of the respective leases and any fixed rate renewal periods, if applicable. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off.

     Acquired above-market leases, net consisted of the following (in thousands):

		June 30,				December 31,
		2008				2007
Acquired above-market leases		$	12,729			$	12,729
Accumulated amortization			(7,712	)			(6,984	)
		$	5,017			$	5,745

     Acquired below-market leases, net consisted of the following (in thousands):

		June 30,				December 31,
		2008				2007
Acquired below-market leases		$	37,961			$	37,961
Accumulated amortization			(17,259	)			(14,253	)
		$	20,702			$	23,708

     Substantially all rental operations expenses, consisting of real estate taxes, insurance and common area maintenance costs are subject to recovery from tenants under the terms of lease agreements. Amounts recovered are dependent on several factors, including occupancy and lease terms. Revenues are recognized in the period the expenses are incurred. The reimbursements are recognized and presented in accordance with EITF 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent (“EITF 99-19”). EITF 99-19 requires that these reimbursements be recorded gross, as the Company is generally the primary obligor with respect to purchasing goods and services from third-party suppliers, has discretion in selecting the supplier and bears the credit risk.

     Lease termination fees are recognized when the related leases are canceled and the Company has no continuing obligation to provide services to such former tenants. A gain on early termination of leases of $2.9 million and $7.7 million for the three and six months ended June 30, 2007 is included in other income in the 2007 consolidated statements of income. A portion of the related straight-line rent receivable and remaining other related intangible assets corresponding to the lease terminations was amortized in 2006 and approximately $1.6 million was fully amortized in the three and six months ended June 30, 2007.

Share-Based Payments

     Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), Share-Based Payment, requires that all share-based payments to employees be recognized in the income statement based on their fair-value. The fair-value is recorded based on the market value of the common stock on the grant date and is amortized to general and administrative expense and rental operations expense over the relevant service period, adjusted for anticipated forfeitures. Through the six months ended June 30, 2008, the Company had only awarded restricted stock and long-term incentive plan (“LTIP”) unit grants under its incentive award plan (see Note 8), which are valued based on the closing market price of the underlying common stock on the date of grant, and had not granted any stock options.

Assets and Liabilities Measured at Fair-Value

     On January 1, 2008, the Company adopted SFAS No. 157, Fair Value Measurements (“SFAS 157”), which defines fair-value, establishes a framework for measuring fair-value, and expands disclosures about fair-value measurements. SFAS 157 applies to reported balances that are required or permitted to be measured at fair-value under existing accounting pronouncements; accordingly, the standard does not require any new fair-value measurements of reported balances.

     On January 1, 2008, the Company adopted SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, which permits companies to choose to measure certain financial instruments and other items at fair-value in order to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently. However, the Company has not elected to measure any additional financial instruments and other items at fair-value (other than those previously required under other GAAP rules or standards) under the provisions of this standard.

     SFAS 157 emphasizes that fair-value is a market-based measurement, not an entity-specific measurement. Therefore, a fair-value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair-value measurements, SFAS 157 establishes a fair-value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

     Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair-value measurement is based on inputs from different levels of the fair-value hierarchy, the level in the fair-value hierarchy within which the entire fair-value measurement falls is based on the lowest level input that is significant to the fair-value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair-value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

     Currently, the Company uses forward starting and interest rate swaps to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair-values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with the provisions of SFAS 157, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair-value measurements. In adjusting the fair-value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

     Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair-value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2008, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair-value hierarchy (see Note 12).

     No other assets or liabilities are measured at fair-value on a recurring basis, or have been measured at fair-value on a non-recurring basis subsequent to initial recognition, in the accompanying consolidated balance sheets as of June 30, 2008.

Derivative Instruments

     The Company records all derivatives on the consolidated balance sheet at fair-value. The accounting for changes in the fair-value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair-value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair-value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

     For derivatives designated as cash flow hedges, the effective portion of changes in the fair-value of the derivative is initially reported in other comprehensive income (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings. If charges relating to the hedged transaction are being deferred pursuant to redevelopment or development activities, the effective portion of changes in the fair-value of the derivative are also deferred in other comprehensive income on the consolidated balance sheet, and are amortized to the income statement once the deferred charges from the hedged transaction begin again to affect earnings. The ineffective portion of changes in the fair-value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged item or transaction.

     The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements or other identified risks. To accomplish this objective, the Company primarily uses interest rate swaps as part of its cash flow hedging strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount. During 2007 and the six months ended June 30, 2008, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt and future variability in the interest-related cash flows from forecasted issuances of debt (see Notes 6 and 12). The Company formally documents the hedging relationships for all derivative instruments, accounts for all of its interest rate swap agreements as cash flow hedges, and does not use derivatives for trading or speculative purposes.

Management’s Estimates

     Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reporting of revenues and expenses during the reporting period to prepare these consolidated financial statements in conformity with GAAP. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions or conditions.

Segment Information

     The Company’s properties share the following similar economic and operating characteristics: (1) they have similar forecasted returns (measured by capitalization rate at acquisition), (2) they are generally occupied almost exclusively by life science tenants that are public companies, government agencies or their subsidiaries, (3) they are generally located near areas of high life science concentrations with similar demographics and site characteristics, (4) the majority of properties are designed specifically for life science tenants that require infrastructure improvements not generally found in standard properties, and (5) the associated leases are primarily triple-net leases, generally with a fixed rental rate and scheduled annual escalations, that provide for a recovery of close to 100% of operating expenses. Consequently, the Company’s properties qualify for aggregation into one operating segment under the provisions of SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information.

Reclassifications

     Certain prior year amounts have been reclassified to conform to the current year presentation.

3. Minority Interests

     Minority interests on the consolidated balance sheets relate primarily to the partnership and LTIP units in the Operating Partnership (collectively, the “Units”) that are not owned by the Company. In conjunction with the formation of the Company, certain persons and entities contributing interests in properties to the Operating Partnership received partnership units. In addition, certain limited partners of the Operating Partnership have received LTIP units in connection with services rendered or to be rendered to the Operating Partnership. Limited partners who have been issued Units have the right to require the Operating Partnership to redeem part or all of their Units upon vesting of the Units, if applicable. The Company may elect to acquire those Units in exchange for shares of the Company’s common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events, or pay cash based upon the fair market value of an equivalent number of shares of the Company’s common stock at the time of redemption. The value of the Units not owned by the Company, had such units been redeemed at June 30, 2008, was approximately $87.9 million based on the average closing price of the Company’s common stock of $25.08 per share for the ten consecutive trading days immediately preceding June 30, 2008.

     The following table shows the vested ownership interests in the Operating Partnership:

		June 30, 2008								December 31, 2007
		Partnership Units				Percentage of				Partnership Units				Percentage of
		and LTIP Units				Total				and LTIP Units				Total
BioMed Realty Trust			71,513,333				95.9	%			65,308,702				95.7	%
Minority interest consisting of:
Partnership and LTIP units held by employees and related parties			2,887,644				3.9	%			2,726,172				4.0	%
Partnership units held by third parties			190,392				0.2	%			190,392				0.3	%
Total			74,591,369				100.0	%			68,225,266				100.0	%

     The accompanying consolidated financial statements include investments in four variable interest entities in which the Company was considered to be the primary beneficiary under FIN 46R for the periods presented. As of June 30, 2008, the Company had a 70% interest in the limited liability company that owns the Fairview property and an 87.5% interest in the limited liability company that owns the Ardenwood Venture property. These entities are consolidated in the accompanying consolidated financial statements. Equity interests in these partnerships not owned by the Company are classified as minority interest on the consolidated balance sheets as of June 30, 2008. Subject to certain conditions, the Company and the holder of the minority interest in the Fairview limited liability company can purchase the other member’s interests (“put-call option”) and the Company has the right to purchase the other member’s interest or sell its own interest in the Ardenwood limited liability company (“buy-sell option”). The estimated fair-values of these options are not material and the Company believes that it will have adequate resources to settle the options if exercised. On October 1, 2007, pursuant to the exercise of a put option by the minority interest limited partner in the limited partnership that owned the King of Prussia property, the Company completed the purchase of the remaining 11% interest in the limited partnership for consideration of approximately $1.8 million, excluding closing costs. In addition, on June 2, 2008, pursuant to the exercise of a put option by the minority interest member, the Company completed the purchase of the remaining 30% interest in the limited liability company that owned the Waples Street property for consideration of approximately $1.8 million, excluding closing costs.

4. Stockholders’ Equity

     During the six months ended June 30, 2008, the Company issued restricted stock awards to employees and to members of its board of directors totaling 21,981 and 10,000 shares, respectively, of common stock (12,327 shares were forfeited during the same period), which are included in the total of common stock outstanding as of the period end (see Note 7). During the six months ended June 30, 2008, the Company also issued 185,434 LTIP units to employees, which are also included in the total of common stock outstanding as of the period end (see
Note 7).

     On April 22, 2008, the Company completed a common stock offering of 6,129,000 shares, including the exercise of an over-allotment option of 429,000 shares, at $25.50 per share, resulting in net proceeds of approximately $149.7 million. The net proceeds to the Company were utilized to repay a portion of the outstanding indebtedness on the unsecured line of credit and for general corporate and working capital purposes.

     In June 2007, the Company adopted a Dividend Reinvestment Program and a Cash Option Purchase Plan (collectively, the “DRIP Plan”) to provide existing stockholders of the Company with an opportunity to invest automatically the cash dividends paid upon shares of the Company’s common stock held by them, as well as permit existing and prospective stockholders to make voluntary cash purchases. Participants may elect to reinvest a portion of, or the full amount of cash dividends paid, whereas optional cash purchases are normally limited to a maximum amount of $10,000. In addition, the Company may elect to establish a discount ranging from 0% to 5% from the market price applicable to newly issued shares of common stock purchased directly from the Company. The Company may change the discount, initially set at 0%, at its discretion, but may not change the discount more frequently than once in any three-month period. Shares purchased under the DRIP Plan shall be, at the Company’s option, purchased from either (1) authorized, but previously unissued shares of common stock, (2) shares of common stock purchased in the open market or privately negotiated transactions, or (3) a combination of both.

Common Stock, Partnership Units and LTIP Units

     As of June 30, 2008, the Company had outstanding 71,719,958 shares of common stock and 2,863,564 and 640,150 partnership and LTIP units, respectively. A share of the Company’s common stock and the partnership and LTIP units have essentially the same economic characteristics as they share equally in the total net income or loss and distributions of the Operating Partnership. The partnership units are further discussed in Note 3 and the LTIP units are discussed in Notes 3 and 8.

7.375% Series A Cumulative Redeemable Preferred Stock

     As of June 30, 2008, the Company had outstanding 9,200,000 shares of 7.375% Series A cumulative redeemable preferred stock, or Series A preferred stock. Dividends are cumulative on the Series A preferred stock from the date of original issuance in the amount of $1.84375 per share each year, which is equivalent to 7.375% of the $25.00 liquidation preference per share. Dividends on the Series A preferred stock are payable quarterly in arrears on or about the 15th day of January, April, July and October of each year. Following a change in control, if the Series A preferred stock is not listed on the New York Stock Exchange, the American Stock Exchange or the Nasdaq Global Market, holders will be entitled to receive (when and as authorized by the board of directors and declared by the Company), cumulative cash dividends from, but excluding, the first date on which both the change of control and the delisting occurred at an increased rate of 8.375% per annum of the $25.00 liquidation preference per share (equivalent to an annual rate of $2.09375 per share) for as long as the Series A preferred stock is not listed. The Series A preferred stock does not have a stated maturity date and is not subject to any sinking fund or mandatory redemption provisions. Upon liquidation, dissolution or winding up, the Series A preferred stock will rank senior to the Company’s common stock with respect to the payment of distributions and other amounts. The Company is not allowed to redeem the Series A preferred stock before January 18, 2012, except in limited circumstances to preserve its status as a REIT. On or after January 18, 2012, the Company may, at its option, redeem the Series A preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends on such Series A preferred stock up to, but excluding the redemption date. Holders of the Series A preferred stock generally have no voting rights except for limited voting rights if the Company fails to pay dividends for six or more quarterly periods (whether or not consecutive) and in certain other circumstances. The Series A preferred stock is not convertible into or exchangeable for any other property or securities of the Company.

     Premiums were recorded upon assumption of the mortgage notes payable at the time of acquisition to account for above-market interest rates. Amortization of these premiums is recorded as a reduction to interest expense over the remaining term of the respective note using the effective-interest method.

     The Company intends to repay any principal and accrued interest due in 2008 through the use of cash from operations or borrowings from its unsecured line of credit.

6. Credit Facilities, Exchangeable Senior Notes, and Other Debt Instruments

Unsecured Line of Credit

     The Company’s unsecured line of credit with KeyBank National Association (“KeyBank”) and other lenders has a borrowing capacity of $600.0 million and a maturity date of August 1, 2011. The unsecured line of credit bears interest at a floating rate equal to, at the Company’s option, either (1) reserve adjusted LIBOR plus a spread which ranges from 100 to 155 basis points, depending on the Company’s leverage, or (2) the higher of (a) the prime rate then in effect plus a spread which ranges from 0 to 25 basis points, or (b) the federal funds rate then in effect plus a spread which ranges from 50 to 75 basis points, in each case, depending on the Company’s leverage. The Company may increase the amount of the unsecured line of credit to $1.0 billion subject to certain conditions. In addition, the Company, at its sole discretion, may extend the maturity date of the unsecured line of credit to August 1, 2012 after satisfying certain conditions and paying an extension fee based on the then current facility commitment. In September 2007, the Company entered into three interest rate swap agreements, which were intended to have the effect of initially fixing the interest rate on $205.0 million of the unsecured line of credit at a weighted average rate of 5.9% through September 2008. The Company has deferred the loan costs associated with the subsequent amendments to the unsecured line of credit, which are being amortized to expense with the unamortized loan costs from the original debt facility over the remaining term. At June 30, 2008, the Company had $213.2 million in outstanding borrowings on its unsecured line of credit, with a weighted average interest rate of 4.9% on the unhedged portion of the outstanding debt of approximately $8.2 million.

Secured Term Loan

     The Company’s $250.0 million secured term loan from KeyBank and other lenders, which is secured by the Company’s interests in 13 of its properties, has a maturity date of August 1, 2012. The secured term loan bears interest at a floating rate equal to, at the Company’s option, either (1) reserve adjusted LIBOR plus 165 basis points or (2) the higher of (a) the prime rate then in effect plus 25 basis points or (b) the federal funds rate then in effect plus 75 basis points. The secured term loan is also secured by the Company’s interest in any distributions from these properties, a pledge of the equity interests in a subsidiary owning one of these properties, and a pledge of the equity interests in a subsidiary owning an interest in another of these properties. The Company entered into an interest rate swap agreement in connection with the initial closing of the secured term loan, which has the effect of fixing the interest rate on the secured term loan at 5.8% until the interest rate swap expires in 2010. At June 30, 2008, the Company had $250.0 million in outstanding borrowings on its secured term loan.

     The terms of the credit agreements for the unsecured line of credit and the secured term loan include certain restrictions and covenants, which limit, among other things, the payment of dividends and the incurrence of additional indebtedness and liens. The terms also require compliance with financial ratios relating to the minimum amounts of net worth, fixed charge coverage, unsecured debt service coverage, the maximum amount of secured, and secured recourse indebtedness, leverage ratio and certain investment limitations. The dividend restriction referred to above provides that, except to enable the Company to continue to qualify as a REIT for federal income tax purposes, the Company will not make distributions with respect to common stock or other equity interests in an aggregate amount for the preceding four fiscal quarters in excess of 95% of funds from operations, as defined, for such period, subject to other adjustments. Management believes that it was in compliance with the covenants as of June 30, 2008.

Exchangeable Senior Notes

     On September 25, 2006, the Operating Partnership issued $175.0 million aggregate principal amount of its 4.50% Exchangeable Senior Notes due 2026 (the “Notes”). The Notes are general senior unsecured obligations of the Operating Partnership and rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership. Interest at a rate of 4.50% per annum is payable on April 1 and October 1 of each year, beginning on April 1, 2007, until the stated maturity date of October 1, 2026. The terms of the Notes are governed by an indenture, dated September 25, 2006, among the Operating Partnership, as issuer, the Company, as guarantor, and U.S. Bank National Association, as trustee. The Notes contain an exchange settlement feature, which provides that the Notes may, on or after September 1, 2026 or under certain other circumstances, be exchangeable for cash (up to the principal amount of the Notes) and, with respect to excess exchange value, into, at the Company’s option, cash, shares of the Company’s common stock or a combination of cash and shares of common stock at the then applicable exchange rate. The initial exchange rate is 26.4634 shares per $1,000 principal amount of Notes, representing an exchange price of approximately $37.79 per share. If certain designated events occur on or prior to October 6, 2011 and a holder elects to exchange Notes in connection with any such transaction, the Company will increase the exchange rate by a number of additional shares of common stock based on the date the transaction becomes effective and the price paid per share of common stock in the transaction, as set forth in the indenture governing the Notes. The exchange rate may also be adjusted under certain other circumstances, including the payment of cash dividends in excess of $0.29 per share of common stock. The increase in the quarterly cash dividend to $0.335 per share of common stock for each of the first two quarters of 2008 did not result in a material change to the exchange rate. The Operating Partnership may redeem the Notes, in whole or in part, at any time to preserve the Company’s status as a REIT or at any time on or after October 6, 2011 for cash at 100% of the principal amount plus accrued and unpaid interest. The holders of the Notes have the right to require the Operating Partnership to repurchase the Notes, in whole or in part, for cash on each of October 1, 2011, October 1, 2016 and October 1, 2021, or upon the occurrence of a designated event, in each case for a repurchase price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest. At June 30, 2008, the Company had an aggregate principal amount of $175.0 million outstanding under the Notes.

Secured Construction Loan

     The Company’s $550.0 million secured construction loan from KeyBank is secured by the Company’s Center for Life Science | Boston property. The loan is separated into four tranches of notes, tranches A, B-1, B-2 and C, and bears interest at a blended rate equal to, at the Company’s option, either (1) LIBOR plus approximately 122.5 basis points or (2) the higher of (a) the prime rate then in effect or (b) the federal funds rate then in effect plus 50 basis points. The loan matures on November 16, 2009, but the Company may extend the maturity date to November 16, 2010 after satisfying certain conditions and payment of an extension fee. The construction loan requires interest only monthly payments until the maturity date. The Company utilized a portion of the borrowing capacity on the construction loan, along with borrowings on its unsecured line of credit, to acquire the Center for Life Science | Boston property and to fund construction activities. In September 2007, the Company entered into an interest rate swap agreement, which is intended to have the effect of initially fixing the interest rate on $330.0 million of the secured construction loan at a rate of 6.1% through September 2008. The loan includes certain restrictions and covenants, which limit, among other things, the incurrence of additional indebtedness and liens. The loan also requires compliance with financial covenants relating to minimum amounts of net worth, fixed charge coverage, and leverage ratio. Management believes that it was in compliance with these covenants as of June 30, 2008. At June 30, 2008, the Company had outstanding borrowings on the secured construction loan of $484.0 million, with a weighted-average interest rate of 3.7% on the unhedged portion of the outstanding debt of approximately $154.0 million.

     As of June 30, 2008, principal payments due for the Company’s consolidated indebtedness (mortgage notes payable excluding debt premium of $9.8 million, unsecured line of credit, secured term loan, the Notes and the secured construction loan) were as follows (in thousands):

2008		$	19,462
2009			489,023

7. Earnings Per Share

     Earnings per share is calculated based on the weighted-average number of shares of the Company’s common stock outstanding during the period. The effects of the outstanding Units, and the vesting of unvested LTIP units and restricted stock that have been granted, using the treasury method, were dilutive and included in the calculation of diluted weighted-average shares for the three and six months ended June 30, 2008 and 2007. No shares were contingently issuable upon settlement of the excess exchange value pursuant to the exchange settlement feature of the Notes (originally issued in 2006 — see Note 6) as the weighted-average common stock prices of $25.91 and $27.59 for the three months ended June 30, 2008 and 2007, respectively, and $24.20 and $28.04 for the six months ended June 30, 2008 and 2007, respectively, did not exceed the initial exchange price of $37.79 per share. Therefore, potentially issuable shares resulting from settlement of the Notes were not included in the calculation of diluted weighted-average shares. No other shares were considered antidilutive for the three and six months ended June 30, 2008 and 2007.

     Computations of basic and diluted earnings per share in accordance with SFAS No. 128, Earnings per Share (in thousands, except share data) were as follows:

8. Incentive Award Plan

     The Company has adopted the BioMed Realty Trust, Inc. and BioMed Realty, L.P. 2004 Incentive Award Plan (the “Plan”). The Plan provides for grants to directors, employees and consultants of the Company and the Operating Partnership (and their respective subsidiaries) of stock options, restricted stock, LTIP units, stock appreciation rights, dividend equivalents and other incentive awards. The Company has reserved 2,500,000 shares of common stock for issuance pursuant to the Plan, subject to adjustments as set forth in the Plan. As of June 30, 2008, 1,140,142 shares of common stock or awards convertible into or exchangeable for common stock remained available for future issuance under the Plan. Each LTIP unit issued will count as one share of common stock for purposes of calculating the limit on shares that may be issued. Compensation cost for these incentive awards is measured based on the fair-value of the award on the grant date (fair-value is calculated based on the closing price of the Company’s common stock on the date of grant) and is recognized as expense over the respective vesting period, which for restricted stock awards and LTIP units is generally two to five years. Fully vested incentive awards may be settled for either cash or stock depending on the Company’s election and the type of award granted. Participants are entitled to cash dividends and may vote such awarded shares, but the sale or transfer of such shares is limited during the restricted or vesting period. Through June 30, 2008, the Company had only awarded restricted stock grants and LTIP units. The restricted stock grants may only be settled for stock whereas the LTIP units may be redeemed for either cash or common stock, at the Company’s election.

     LTIP units represent a profits interest in the Operating Partnership for services rendered or to be rendered by the LTIP unit holder in its capacity as a partner, or in anticipation of becoming a partner, in the Operating Partnership. Initially, LTIP units do not have full parity with common units of the Operating Partnership with respect to liquidating distributions, although LTIP unit holders receive the same quarterly per unit distributions as common units and may vote the LTIP units from the date of issuance. The LTIP units are subject to vesting requirements, which lapse over a specified period of time (generally three to five years from the date of issuance). In addition, the LTIP units are generally subject to a two-year lock-up period during which time the LTIP units may not be redeemed or sold by the LTIP unit holder. Upon the occurrence of specified events, LTIP units may over time achieve full parity with common units of the Operating Partnership for all purposes. Upon achieving full parity, and after the expiration of any vesting and lock-up periods, LTIP units may be redeemed for an equal number of the Company’s common stock or cash, at the Company’s election.

     During the three months ended June 30, 2008 and 2007, the Company granted 18,300 shares of unvested restricted stock and LTIP units with an aggregate value of $471,000, and 25,000 shares of unvested restricted stock and LTIP units with an aggregate value of $687,000 under the Plan, respectively. For both the three months ended June 30, 2008 and 2007, a total of 10,000 shares of restricted stock and LTIP units vested, with fair-values of $272,000 and $273,000, respectively. During the six months ended June 30, 2008 and 2007, the Company granted 217,415 shares of unvested restricted stock and LTIP units with an aggregate value of $4.9 million, and 327,500 shares of unvested restricted stock and LTIP units with an aggregate value of $9.7 million under the Plan, respectively. For the six months ended June 30, 2008 and 2007, a total of 237,103 and 209,818 shares of restricted stock and LTIP units vested, with fair-values of $5.5 million and $6.0 million, respectively. In each of the three months ended June 30, 2008 and 2007, $1.5 million of stock-based compensation expense was recognized in general and administrative expense and rental operations expense. For the six months ended June 30, 2008 and 2007, $2.8 million and $2.6 million, respectively, of stock-based compensation expense was recognized in general and administrative expense and rental operations expense. As of June 30, 2008, total stock-based compensation expense related to unvested awards of $14.0 million will be recognized in the future over a weighted-average period of 3.2 years.

     A summary of the Company’s unvested restricted stock and LTIP units is presented below:

10. Investment in Unconsolidated Partnerships

     The accompanying consolidated financial statements include investments in two limited liability companies with Prudential Real Estate Investors (“PREI”), which were formed in the second quarter of 2007, and in 10165 McKellar Court, L.P. (“McKellar Court”), a limited partnership with Quidel Corporation, the tenant which occupies the McKellar Court property. One of the PREI limited liability companies, PREI II LLC, is a variable interest entity as defined in FIN 46R; however, the Company is not the primary beneficiary. PREI will bear the majority of any losses. The other PREI limited liability company, PREI I LLC, does not qualify as a variable interest entity as defined in FIN 46R. In addition, consolidation under EITF 04-5 is not required as the Company does not control the limited liability companies. The McKellar Court partnership is a variable interest entity as defined in FIN 46R; however, the Company is not the primary beneficiary. The limited partner at McKellar Court is the only tenant in the property and will bear the majority of any losses. As it does not control the limited liability companies or the partnership, the Company accounts for them under the equity method of accounting. Significant accounting policies used by the unconsolidated partnerships that own these properties are similar to those used by the Company. General information on the PREI limited liability companies and the McKellar Court partnership (each referred to in this footnote individually as a “partnership” and collectively as the “partnerships”) as of June 30, 2008 was as follows:

				Company’s				Company’s
				Ownership				Economic
Name		Partner		Interest				Interest				Date Acquired
PREI I LLC(1)		PREI			20	%			20	%		April 4, 2007
PREI II LLC(2)		PREI			20	%			20	%		April 4, 2007
McKellar Court(3)		Quidel Corporation			21	%			21	%(4)		September 30, 2004

     The Company acts as the operating member or partner, as applicable, and day-to-day manager for these partnerships. The Company is entitled to receive fees for providing construction and development services (as applicable) and management services to the PREI limited liability companies. The Company earned approximately $836,000 and $1.3 million in fees for the three and six months ended June 30, 2008, respectively, and approximately $391,000 in fees for both the three and six months ended June 30, 2007 for services provided to the PREI limited liability companies, which are reflected in tenant recoveries and other income in the consolidated statements of income.

     The condensed combined balance sheets for all of the Company’s unconsolidated partnerships were as follows (in thousands):

     On February 13, 2008, a wholly owned subsidiary of PREI I LLC entered into a secured construction loan facility with Wachovia Bank, National Association and certain other lenders to provide borrowings of up to approximately $245.0 million in connection with the construction of 650 East Kendall Street, a life sciences building located in Cambridge, Massachusetts. Proceeds from the secured construction loan were used in part to repay a portion of the secured acquisition and interim loan facility held by the PREI limited liability companies and will also be used to fund the balance of the anticipated cost to complete construction of the project. In February 2008, the subsidiary entered into an interest rate swap agreement, which is intended to have the effect of initially fixing the interest rate on up to $163.0 million of the secured construction loan facility at a weighted average rate of 4.4% through August 2010. The swap agreement had an original notional amount of $84.0 million based on the initial borrowing on the secured construction loan facility, which will increase on a monthly basis at predetermined amounts as additional borrowings are made. At June 30, 2008, there were $106.9 million in outstanding borrowings on its secured construction loan facility, with a contractual interest rate of 4.0%.

12. Derivatives and Other Financial Instruments

     As of June 30, 2008, the Company had four forward starting swaps hedging a forecasted debt issuance, with a total notional value of $450.0 million, which are valued on the accompanying consolidated balance sheets at their fair-values. At maturity, the Company will either (a) receive payment from the counterparties if the accumulated balance is an asset, or (b) make payment to the counterparties if the accumulated balance is a liability with the resulting receipt or payment deferred and amortized as an increase or decrease to interest expense over the term of the forecasted borrowing.

     As of June 30, 2008, the Company also had five interest rate swaps with an aggregate notional amount of $785.0 million under which at each monthly settlement date the Company either (1) receives the difference between a fixed interest rate (the “Strike Rate”) and one-month LIBOR if the Strike Rate is less than LIBOR or (2) pays such difference if the Strike Rate is greater than LIBOR. One interest rate swap with a notional amount of $250.0 million hedges the Company’s secured term loan. Each of the remaining four interest rate swaps hedges the first interest payments, due on the date that is on or closest after each swap’s settlement date, associated with the amount of LIBOR-based debt equal to each swap’s notional amount. Three of these interest rate swaps have an aggregate notional amount of $205.0 million and are initially intended to hedge interest payments associated with the Company’s unsecured line of credit. The remaining interest rate swap has a notional amount of $330.0 million and is initially intended to hedge interest payments associated with the Company’s secured construction loan. No initial investment was made to enter into the interest rate swap agreements.

     The following is a summary of the terms of the forward starting swaps and the interest rate swaps and their fair-values, which are included in other liabilities on the accompanying consolidated balance sheets (in thousands):

Current												Fair-Value(1)
Notional Amount				Strike Rate				Effective Date		Expiration Date		June 30, 2008				December 31, 2007
$	250,000				4.157	%		June 1, 2005		June 1, 2010		$	(3,941	)		$	(2,830	)
	150,000				5.162	%		December 30, 2008		December 30, 2018			(4,412	)			(4,254	)
	50,000				5.167	%		December 30, 2008		December 30, 2018			(1,489	)			(1,437	)
	100,000				5.167	%		December 30, 2008		December 30, 2018			(2,985	)			(2,874	)

	55,000				4.760	%		September 20, 2007		September 20, 2008			(273	)			(254	)
$	1,235,000											$	(23,264	)		$	(21,768	)

     The decrease/(increase) in net unrealized losses of $30.6 million and ($1.5 million) for the three and six months ended June 30, 2008, respectively, and increase in net unrealized gains of $18.3 million and $18.1 million for the three and six months ended June 30, 2007, respectively, for derivatives designated as cash flow hedges are separately disclosed in the accompanying footnotes to the consolidated financial statements in stockholders’ equity as a component of accumulated other comprehensive income (see Note 4). For the three and six months ended June 30, 2008 and 2007, an immaterial amount of hedge ineffectiveness on cash flow hedges due to mismatches in maturity date and interest rate reset dates of the interest rate swap and debt was recognized in interest expense.

     Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to earnings when the hedged transaction affects earnings. The change in net unrealized losses on cash flow hedges includes a reclassification of net unrealized gains/losses from accumulated other comprehensive income as an increase to interest expense of $2.0 million and $2.8 million for the three and six months ended June 30, 2008, respectively, and a reduction to interest expense of $735,000 and $1.5 million for the three and six months ended June 30, 2007, respectively. In addition, for the three and six months ended June 30, 2008 approximately $1.8 million and $2.8 million, respectively, of settlement payments relating to the $330.0 million interest rate swap have been deferred in other comprehensive income related to the Company’s Center for Life Science | Boston property.

13. New Accounting Standards

     In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (“SFAS 141(R)”). SFAS 141(R) retains the fundamental requirements that purchase method of accounting be used for all business combinations, for an acquirer to be identified for each business combination, and retains the guidance for identifying and recognizing intangible assets separately from goodwill. SFAS 141(R) requires an acquirer to recognize the assets acquired, liabilities assumed and any noncontrolling interest in the acquiree at the acquisition date, measured at their fair-values as of that date, changes the recognition of assets acquired and liabilities assumed arising from contingencies, and changes the recognition and measurement of contingent consideration. In addition, SFAS 141(R) requires that costs incurred to effect the acquisition and restructuring costs that the acquirer expected, but is not obligated to incur, be recognized as an expense separately from the business combination. SFAS 141(R) will also require additional disclosure of information surrounding a business combination, including additional information regarding the nature and financial impact of the business combination. SFAS 141(R) applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008.

     In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements (“SFAS 160”). SFAS 160 clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. SFAS 160 also requires consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and requires disclosure, on the face of the consolidated statement of income, of the amounts of consolidated net income attributable to the parent and to the noncontrolling interest. In addition, SFAS 160 establishes a single method of accounting for changes in a parent’s ownership interest in a subsidiary that does not result in deconsolidation and requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. SFAS 160 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. SFAS 160 may only be applied prospectively, except for the presentation and disclosure requirements, which will be applied retrospectively for all periods presented. The Company is currently evaluating the requirements of this statement and has not yet determined its effect on the Company’s consolidated financial statements.

     In February 2008, the FASB issued Staff Position No. FAS 157-2, which delayed the effective date of SFAS 157 for non-financial assets and liabilities to fiscal years beginning after November 15, 2008. The Company is currently evaluating the effect of the implementation of SFAS 157 on its non-financial assets and non-financial liabilities, but does not believe that it will have on a material impact on its consolidated financial statements.

     In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS 161”) as an amendment to SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS 161 requires that objectives for using derivative instruments be disclosed in terms of underlying risk and accounting designation. SFAS 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008. The Company is currently evaluating the requirements of this statement and has not yet determined its effect on the Company’s consolidated financial statements.

     In May 2008, the FASB issued FASB Staff Position APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlement) (“FSP 14-1”), an interpretation of APB Opinion No. 14, Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants. FSP 14-1 requires the issuer of certain convertible debt instruments that may be settled in cash (or other assets) on conversion to separately account for the liability (debt) and equity (conversion option) components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate. The equity component of the convertible debt will be included in the paid-in capital section of stockholders’ equity and the value of the equity component will be treated as original issue discount for purposes of accounting for the debt component of the debt security. The resulting debt discount will be accreted as additional interest expense over the non-cancellable term of the instrument. FSP 14-1 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2008, with early adoption not permitted. Retrospective application is required for all periods presented. The Company believes FSP 14-1 will result in an increase to interest expense associated with the Notes and also will result in an increase in capitalized interest upon adoption.

     In June 2008, the FASB issued FASB Staff Position EITF 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities (“FSP 03-6-1”), which addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in earnings allocation in computing earnings per share under the two-class method. The statement is effective for financial statements issued for fiscal years beginning after December 15, 2008 and retrospective application is required for all periods presented. The Company is currently evaluating the effect of the implementation of FSP 03-6-1, but does not believe that it will have a material impact on the calculation of earnings per share.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     As used herein, the terms “we”, “us”, “our” or the “Company” refer to BioMed Realty Trust, Inc., a Maryland corporation, and any of our subsidiaries.

     The following discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this report. We make statements in this report that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In particular, statements pertaining to our capital resources, portfolio performance and results of operations contain forward-looking statements. Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods which may be incorrect or imprecise, and we may not be able to realize them. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases. You can also identify forward-looking statements by discussions of strategy, plans or intentions. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, dependence on tenants’ financial condition, and competition from other developers, owners and operators of real estate); adverse economic or real estate developments in the life science industry or our target markets; risks associated with the availability and terms of financing and the use of debt to fund acquisitions and developments; failure to manage effectively our growth and expansion into new markets, or to complete or integrate acquisitions and developments successfully; risks and uncertainties affecting property development and construction; risks associated with downturns in the national and local economies, increases in interest rates, and volatility in the financial and securities markets; potential liability for uninsured losses and environmental contamination; risks associated with our potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, and possible adverse changes in tax and environmental laws; and risks associated with our dependence on key personnel whose continued service is not guaranteed. We disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

     The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in other sections of this report. In addition, we discussed a number of material risks in our annual report on Form 10-K for the year ended December 31, 2007. Those risks continue to be relevant to our performance and financial condition. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our company’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

Overview

     We operate as a REIT focused on acquiring, developing, owning, leasing and managing laboratory and office space for the life science industry. Our tenants primarily include biotechnology and pharmaceutical companies, scientific research institutions, government agencies and other entities involved in the life science industry. Our properties are generally located in markets with well-established reputations as centers for scientific research, including Boston, San Diego, San Francisco, Seattle, Maryland, Pennsylvania and New York/New Jersey.

     At June 30, 2008, our portfolio consisted of 69 properties, representing 112 buildings with an aggregate of approximately 10.4 million rentable square feet, including 1.9 million square feet of development in progress. We also owned undeveloped land parcels adjacent to existing properties that we estimate can support up to 1.4 million rentable square feet of laboratory and office space.

     The following reflects the classification of our properties between stabilized properties (operating properties in which more than 90% of the rentable square footage is under lease), lease up properties (operating properties in which less than 90% of the rentable square footage is under lease), repositioning and redevelopment properties (properties that are currently being prepared for their intended use), construction in progress (properties that are currently under development through ground up construction), and land parcels (representing management’s estimates of rentable square footage if development of these properties was undertaken) at June 30, 2008:
