NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2008

1. Organization and description of business

PS Business Parks, Inc. (“PSB”) was incorporated in the state of California in 1990. As of September 30, 2008, PSB owned approximately 73.7% of the common partnership units of PS Business Parks, L.P. (the “Operating Partnership” or “OP”). The remaining common partnership units were owned by Public Storage (“PS”). PSB, as the sole general partner of the Operating Partnership, has full, exclusive and complete responsibility and discretion in managing and controlling the Operating Partnership. PSB and the Operating Partnership are collectively referred to as the “Company.”

The Company is a fully-integrated, self-advised and self-managed real estate investment trust (“REIT”) that acquires, develops, owns and operates commercial properties, primarily multi-tenant flex, office and industrial space. As of September 30, 2008, the Company owned and operated approximately 19.6 million rentable square feet of commercial space located in eight states. The Company also manages approximately 1.4 million rentable square feet on behalf of PS and its affiliated entities.

References to the number of properties or square footage are unaudited and outside the scope of the Company’s independent registered public accounting firm’s review of the Company’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).

2. Summary of significant accounting policies

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2008 are not necessarily indicative of the results that may be expected for the year ended December 31, 2008. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

The accompanying consolidated financial statements include the accounts of PSB and the Operating Partnership. All significant inter-company balances and transactions have been eliminated in the consolidated financial statements.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Allowance for doubtful accounts

The Company monitors the collectibility of its receivable balances including the deferred rent receivable on an ongoing basis. Based on these reviews, the Company maintains an allowance for doubtful accounts for estimated losses resulting from the possible inability of tenants to make contractual rent payments to the Company. A provision for doubtful accounts is recorded during each period. The allowance for doubtful accounts, which represents the cumulative allowances less write-offs of uncollectible rent, is netted against tenant and other receivables on the consolidated balance sheets. Tenant receivables are net of an allowance for uncollectible accounts totaling $300,000 at September 30, 2008 and December 31, 2007.

Financial instruments

The methods and assumptions used to estimate the fair value of financial instruments are described below. The Company has estimated the fair value of financial instruments using available market information and appropriate valuation methodologies. Considerable judgment is required in interpreting market data to develop estimates of market value. Accordingly, estimated fair values are not necessarily indicative of the amounts that could be realized in current market exchanges.

The Company considers all highly liquid investments with a remaining maturity of three months or less at the date of purchase to be cash equivalents. Due to the short period to maturity of the Company’s cash and cash equivalents, accounts receivable, other assets and accrued and other liabilities, the carrying values as presented on the consolidated balance sheets are reasonable estimates of fair value. Based on borrowing rates currently available to the Company, the carrying amount of debt approximates fair value.

Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and receivables. Cash and cash equivalents, which consist primarily of short-term investments, including commercial paper, are only invested in entities with an investment grade rating. Receivables are comprised of balances due from a large number of customers. Balances that the Company expects to become uncollectible are reserved for or written off.

Real estate facilities

Real estate facilities are recorded at cost. Costs related to the renovation or improvement of the properties are capitalized. Expenditures for repairs and maintenance are expensed as incurred. Expenditures that are expected to benefit a period greater than two years and exceed $2,000 are capitalized and depreciated over the estimated useful life. Buildings and equipment are depreciated on the straight-line method over the estimated useful lives, which are generally 30 and five years, respectively. Leasing costs in excess of $1,000 for leases with terms greater than two years are capitalized and depreciated over their estimated useful lives. Leasing costs for leases of less than two years or less than $1,000 are expensed as incurred. Interest cost and property taxes incurred during the period of construction of real estate facilities are capitalized.

Intangible assets/liabilities

Intangible assets and liabilities include above-market and below-market in-place lease values of acquired properties based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The capitalized above-market and below-market lease values (included in other assets and accrued liabilities in the accompanying consolidated balance sheets) are amortized, net, to rental income over the remaining non-cancelable terms of the respective leases. The Company recorded net amortization of $49,000 and $44,000 of intangible assets and liabilities resulting from the above-market and below-market lease values during the three months ended September 30, 2008 and 2007, respectively. Net amortization was $145,000 and $53,000 for each of the nine months ended September 30, 2008 and 2007, respectively. As of September 30, 2008, the value of in-place leases resulted in a net intangible asset of $240,000, net of $952,000 of accumulated amortization, and a net intangible liability of $693,000, net of $664,000 of accumulated amortization. As of December 31, 2007, the value of in-place leases resulted in a net intangible asset of $419,000, net of $773,000 of accumulated amortization, and a net intangible liability of $1.0 million, net of $340,000 of accumulated amortization.

Evaluation for asset impairments

The Company evaluates its assets used in operations by identifying indicators of impairment and by comparing the sum of the estimated undiscounted future cash flows for each asset to the asset’s carrying value. When indicators of impairment are present and the sum of the undiscounted future cash flows is less than the carrying value of such asset, an impairment loss is recorded equal to the difference between the asset’s current carrying value and its value based on discounting its estimated future cash flows. In addition, the Company evaluates its assets held for disposition for impairment. Assets held for disposition are reported at the lower of their carrying value or fair value, less cost of disposition. At September 30, 2008, the Company did not consider any assets to be impaired.

Stock-based compensation

Stock-based compensation is accounted for in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 123(R) “Share-Based Payment,” which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. See Note 11.

Revenue and expense recognition

Revenue is recognized in accordance with Staff Accounting Bulletin No. 104 of the Securities and Exchange Commission, Revenue Recognition in Financial Statements (“SAB 104”). SAB 104 requires that four basic criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; the delivery has occurred or services rendered; the fee is fixed or determinable; and collectibility is reasonably assured. All leases are classified as operating leases. Rental income is recognized on a straight-line basis over the terms of the leases. Straight-line rent is recognized for all tenants with contractual increases in rent that are not included on the Company’s credit watch list. Deferred rent receivable represents rental revenue recognized on a straight-line basis in excess of billed rents. Reimbursements from tenants for real estate taxes and other recoverable operating expenses are recognized as revenues in the period the applicable costs are incurred. Property management fees are recognized in the period earned.

Costs incurred in connection with leasing (primarily tenant improvements and lease commissions) are capitalized and amortized over the lease period.

Gains from sales of real estate

The Company recognizes gains from the sale of real estate at the time of the sale using the full accrual method, provided that various criteria related to the terms of the transactions and any subsequent involvement by the Company with the properties sold are met. If the criteria are not met, the Company defers the gains and recognizes them when the criteria are met or using the installment or cost recovery methods as appropriate under the circumstances.

General and administrative expense

General and administrative expense includes executive and other compensation, office expense, professional fees, state income taxes and other such administrative items.

Income taxes

The Company qualified and intends to continue to qualify as a REIT, as defined in Section 856 of the Internal Revenue Code. As a REIT, the Company is not subject to federal income tax to the extent that it distributes its taxable income to its shareholders. A REIT must distribute at least 90% of its taxable income each year. In addition, REITs are subject to a number of organizational and operating requirements. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax (including any applicable alternative minimum tax) based on its taxable income using corporate income tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and to federal income and excise taxes on its undistributed taxable income. The Company believes it met all organizational and operating requirements to maintain its REIT status during 2007 and intends to continue to meet such requirements for 2008. Accordingly, no provision for income taxes has been made in the accompanying consolidated financial statements.

In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 is an interpretation of FASB Statement No. 109, “Accounting for Income Taxes,” and it seeks to reduce the diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. In addition, FIN 48 provides guidance on derecognition, classification, interest and penalties, and accounting in interim periods and requires expanded disclosure with respect to the uncertainty in income taxes. The Company adopted FIN 48 as of January 1, 2007 and did not record any adjustment as a result of such adoption.

Accounting for preferred equity issuance costs

In accordance with Emerging Issues Task Force (“EITF”) Topic D-42, the Company records its issuance costs as a reduction to paid-in capital on its balance sheet at the time the preferred securities are issued and reflects the carrying value of the preferred stock at the stated value. The Company records issuance costs as non-cash preferred equity distributions at the time it notifies the holders of preferred stock or units of its intent to redeem such shares or units.

Net income per common share

Per share amounts are computed using the number of weighted average common shares outstanding. “Diluted” weighted average common shares outstanding includes the dilutive effect of stock options and restricted stock units under the treasury stock method. “Basic” weighted average common shares outstanding excludes such effect. Earnings per share has been calculated as follows (in thousands, except per share amounts):

		For the Three Months								For the Nine Months
		Ended September 30,								Ended September 30,
		2008				2007				2008				2007
Net income allocable to common shareholders		$	5,396			$	4,267			$	13,821			$	13,971
Weighted average common shares outstanding:
Basic weighted average common shares outstanding			20,448				21,345				20,438				21,332
Net effect of dilutive stock compensation — based on treasury stock method using average market price			242				271				236				338
Diluted weighted average common shares outstanding			20,690				21,616				20,674				21,670
Net income per common share — Basic		$	0.26			$	0.20			$	0.68			$	0.65
Net income per common share — Diluted		$	0.26			$	0.20			$	0.67			$	0.64

Options to purchase approximately 66,000 shares for the three and nine months ended September 30, 2008 were not included in the computation of diluted net income per share because such options were considered anti-dilutive. Options to purchase approximately 52,000 and 32,000 shares for the three and nine months ended September 30, 2007, respectively, were not included in the computation of diluted net income per share because such options were considered anti-dilutive.

Segment reporting

The Company views its operations as one segment.

3. Real estate facilities

The activity in real estate facilities for the nine months ended September 30, 2008 is as follows (in thousands):

						Buildings and				Accumulated
		Land				Equipment				Depreciation				Total
Balances at December 31, 2007		$	494,849			$	1,484,049			$	(539,857	)		$	1,439,041
Capital improvements, net			—				28,985				—				28,985
Disposals			—				(1,485	)			1,485				—
Depreciation expense			—				—				(75,270	)			(75,270	)
Balances at September 30, 2008		$	494,849			$	1,511,549			$	(613,642	)		$	1,392,756

In accordance with SFAS No. 141, “Business Combinations,” the purchase price of acquired properties is allocated to land, buildings and equipment and identified tangible and intangible assets and liabilities associated with in-place leases (including tenant improvements, unamortized lease commissions, value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any) based on their respective estimated fair values.

In determining the fair value of the tangible assets of the acquired properties, management considers the value of the properties as if vacant as of the acquisition date. Management must make significant assumptions in determining the value of assets and liabilities acquired. Using different assumptions in the allocation of the purchase cost of the acquired properties would affect the timing of recognition of the related revenue and expenses. Amounts allocated to land are derived from comparable sales of land within the same region. Amounts allocated to buildings and improvements, tenant improvements and unamortized lease commissions are based on current market replacement costs and other market information. The amount allocated to acquired in-place leases is determined based on management’s assessment of current market conditions and the estimated lease-up periods for the respective spaces.

The following table summarizes assets acquired and liabilities assumed during the nine months ended September 30, 2007 (in thousands):

Land		$	53,930
Buildings			88,006
In-place leases			(1,357	)
Total purchase price			140,579
Net operating assets and liabilities acquired			(1,643	)
Total cash paid		$	138,936

The Company did not acquire any assets or assume any liabilities during the nine months ended September 30, 2008.

4. Leasing activity

The Company leases space in its real estate facilities to tenants primarily under non-cancelable leases generally ranging from one to 10 years. Future minimum rental revenues excluding recovery of operating expenses as of September 30, 2008 under these leases are as follows (in thousands):

2008		$	55,636
2009			197,939
2010			151,003
2011			106,462
2012			71,157
Thereafter			103,452
Total		$	685,649

In addition to minimum rental payments, certain tenants reimburse the Company for their pro-rata share of specified operating expenses. Such reimbursements amounted to $13.7 million and $11.7 million for the three months ended September 30, 2008 and 2007, respectively and $40.2 million and $33.5 million for the nine months ended September 30, 2008 and 2007, respectively. These amounts are included as rental income in the accompanying consolidated statements of income.

Leases accounting for approximately 6.0% of the leased square footage are subject to termination options which include leases for approximately 2.0% of the total leased square footage having termination options exercisable through December 31, 2008. In general, these leases provide for termination payments should the termination options be exercised. The above table is prepared assuming such options are not exercised.

5. Bank loans

On July 30, 2008, the Company extended the term of its line of credit (the “Credit Facility”) with Wells Fargo Bank to August 1, 2010. The Credit Facility has a borrowing limit of $100.0 million. Interest on outstanding borrowings is payable monthly. At the option of the Company, the rate of interest charged is equal to (i) the prime rate or (ii) a rate ranging from the London Interbank Offered Rate (“LIBOR”) plus 0.70% to LIBOR plus 1.50% depending on the Company’s credit ratings and coverage ratios, as defined (currently LIBOR plus 0.85%). In addition, the Company is required to pay an annual commitment fee ranging from 0.15% to 0.30% of the borrowing limit (currently 0.20%). In connection with the modification of the Credit Facility, the Company paid a fee of $300,000, which is being amortized over the life of the Credit Facility. The Company had no balance outstanding as of September 30, 2008 or December 31, 2007. The Credit Facility requires the Company to meet certain covenants, and the Company was in compliance with all such covenants at September 30, 2008.

7. Minority interests

Common partnership units

The Company presents the accounts of PSB and the Operating Partnership on a consolidated basis. Ownership interests in the Operating Partnership that can be redeemed for common stock, other than PSB’s interest, are classified as minority interest in income — common units in the consolidated financial statements. Minority interest in income consists of the minority interests’ share of the consolidated operating results after allocation to preferred units and shares. Beginning one year from the date of admission as a limited partner (common units) and subject to certain limitations described below, each limited partner other than PSB has the right to require the redemption of its partnership interest.

A limited partner (common units) that exercises its redemption right will receive cash from the Operating Partnership in an amount equal to the market value (as defined in the Operating Partnership Agreement) of the partnership interests redeemed. In lieu of the Operating Partnership redeeming the partner for cash, PSB, as general partner, has the right to elect to acquire the partnership interest directly from a limited partner exercising its redemption right, in exchange for cash in the amount specified above or by issuance of one share of PSB common stock for each unit of limited partnership interest redeemed.

A limited partner (common units) cannot exercise its redemption right if delivery of shares of PSB common stock would be prohibited under the applicable articles of incorporation, if the general partner believes that there is a risk that delivery of shares of common stock would cause the general partner to no longer qualify as a REIT, would cause a violation of the applicable securities laws, or would result in the Operating Partnership no longer being treated as a partnership for federal income tax purposes.

At September 30, 2008, there were 7,305,355 common units owned by PS, which are accounted for as minority interests. On a fully converted basis, assuming all 7,305,355 minority interest common units were converted into shares of common stock of PSB at September 30, 2008, the minority interest units would convert into approximately 26.3% of the common shares outstanding. Combined with PS’s common stock ownership, on a fully converted basis, PS has a combined ownership of approximately 45.8% of the Company’s common equity. At the end of each reporting period, the Company determines the amount of equity (book value of net assets) which is allocable to the minority interest based upon the ownership interest, and an adjustment is made to the minority interest, with a corresponding adjustment to paid-in capital, to reflect the minority interests’ equity in the Company.

Preferred partnership units

Through the Operating Partnership, the Company has the following preferred units outstanding as of September 30, 2008 and December 31, 2007 (in thousands):

														September 30, 2008								December 31, 2007

Total															3,790			$	94,750				3,790			$	94,750

During the first quarter of 2007, the Company completed a private placement of $12.0 million of preferred units through its Operating Partnership. The 6.550% Series Q Cumulative Redeemable Preferred Units are non-callable for five years and have no mandatory redemption.

The Operating Partnership has the right to redeem preferred units on or after the fifth anniversary of the applicable issuance date at the original capital contribution plus the cumulative priority return, as defined, to the redemption date to the extent not previously distributed. The preferred units are exchangeable for Cumulative Redeemable Preferred Stock of the respective series of PSB on or after the tenth anniversary of the date of issuance at the option of the Operating Partnership or a majority of the holders of the respective preferred units. The Cumulative Redeemable Preferred Stock will have the same distribution rate and par value as the corresponding preferred units and will otherwise have equivalent terms to the other series of preferred stock described in Note 9. As of September 30, 2008, the Company had $2.7 million of deferred costs in connection with the issuance of preferred units, which the Company will report as additional distributions upon notice of redemption.

8. Related party transactions

Pursuant to a cost sharing and administrative services agreement, the Company shares costs with PS and its affiliated entities for certain administrative services, which are allocated among PS and its affiliates in accordance with a methodology intended to fairly allocate those costs. These costs totaled $97,000 and $76,000 for the three months ended September 30, 2008 and 2007, respectively and $292,000 and $227,000 for the nine months ended September 30, 2008 and 2007, respectively.

Under the property management contracts, the Operating Partnership is compensated based on a percentage of the gross revenues of the facilities managed. Under the supervision of the property owners, the Operating Partnership coordinates rental policies, rent collections, marketing activities, the purchase of equipment and supplies, maintenance activities, and the selection and engagement of vendors, suppliers and independent contractors. In addition, the Operating Partnership assists and advises the property owners in establishing policies for the hire, discharge and supervision of employees for the operation of these facilities, including property managers and leasing, billing and maintenance personnel.

The property management contract with PS is for a seven-year term with the agreement automatically extending for an additional one-year period upon each one-year anniversary of its commencement (unless cancelled by either party). Either party can give notice of its intent to cancel the agreement upon expiration of its current term. Management fee revenues under these contracts were $178,000 and $177,000 for the three months ended September 30, 2008 and 2007, respectively and $550,000 and $542,000 for the nine months ended September 30, 2008 and 2007, respectively.

In December, 2006, PS began providing property management services for the mini storage component of two assets owned by the Company. These mini storage facilities, located in Palm Beach County, Florida, operate under the “Public Storage” name.

Under the property management contracts, PS is compensated based on a percentage of the gross revenues of the facilities managed. Under the supervision of the Company, PS coordinates rental policies, rent collections, marketing activities, the purchase of equipment and supplies, maintenance activities, and the selection and engagement of vendors, suppliers and independent contractors. In addition, PS assists and advises the Company in establishing policies for the hire, discharge and supervision of employees for the operation of these facilities, including on-site managers, assistant managers and associate managers.

11. Stock-based compensation

PSB has a 1997 Stock Option and Incentive Plan (the “1997 Plan”) and a 2003 Stock Option and Incentive Plan (the “2003 Plan”), each covering 1.5 million shares of PSB’s common stock. Under the 1997 Plan and 2003 Plan, PSB has granted non-qualified options to certain directors, officers and key employees to purchase shares of PSB’s common stock at a price no less than the fair market value of the common stock at the date of grant. Additionally, under the 1997 Plan and 2003 Plan, PSB has granted restricted stock units to officers and key employees.

The weighted average grant date fair value of the options granted during the nine months ended September 30, 2008 and 2007 were $8.50 per share and $12.11 per share, respectively. The Company has calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions used for grants during the nine months ended September 30, 2008 and 2007, respectively; a dividend yield of 3.1% and 2.6%; expected volatility of 19.1% and 18.2%; expected life of five years; and risk-free interest rates of 3.1% and 4.5%.

The weighted average grant date fair value of restricted stock units granted during the nine months ended September 30, 2008 and 2007 were $52.66 and $67.88, respectively. The Company calculated the fair value of each restricted stock unit grant using the market value on the date of grant.

At September 30, 2008, there were a combined total of 1.2 million options and restricted stock units authorized to grant. Information with respect to outstanding options and nonvested restricted stock units granted under the 1997 Plan and 2003 Plan is as follows:

12. Recent accounting pronouncements

In December 2007, the FASB issued SFAS No. 141 (R), “Business Combinations” (“SFAS 141R”), to create greater consistency in the accounting and financial reporting of business combinations. SFAS 141R requires a company to recognize the assets acquired, the liabilities assumed, and any noncontrolling interest in the acquired entity to be measured at their fair values as of the acquisition date. SFAS 141R also requires companies to recognize the fair value of assets acquired, the liabilities assumed and any noncontrolling interest in acquisitions of less than a 100% interest when the acquisition constitutes a change in control of the acquired entity. In addition, SFAS 141R requires that acquisition-related costs and restructuring costs be recognized separately from the business combination and expensed as incurred. SFAS 141R is effective for business combinations for which the acquisition date is on or after January 1, 2009. Early adoption is prohibited. The Company is currently evaluating the impact of SFAS 141R on our consolidated financial statements.

Effective January 1, 2008, the Company adopted, on a prospective basis, SFAS No. 157, “Fair Value Measurements” (“SFAS 157”) as amended by FASB Staff Position SFAS 157-1, “Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13” (“FSP FAS 157-1”) and FASB Staff Position SFAS 157-2, “Effective Date of FASB Statement No. 157” (“FSP FAS 157-2”). SFAS 157 defines fair value, establishes a framework for measuring fair value according to GAAP and provides for expanded disclosure about fair value measurements. SFAS 157 applies prospectively to all other accounting pronouncements that require or permit fair value measurements. FSP FAS 157-1 amends SFAS 157 to exclude from the scope of SFAS 157 certain leasing transactions accounted for under SFAS No. 13, “Accounting for Leases.” FSP FAS 157-2 amends SFAS 157 to defer the effective date of SFAS 157 for all non-financial assets and non-financial liabilities except those that are recognized or disclosed at fair value in the financial statements on a recurring basis to fiscal years beginning after November 15, 2008.

The adoption of SFAS 157 did not have a material impact on the Company’s consolidated financial statements. Management is evaluating the impact that SFAS 157 will have on its non-financial assets and non-financial liabilities since the application of SFAS 157 for such items was deferred to January 1, 2009. The Company believes that the impact of these items will not be material to its consolidated financial statements.

Effective January 1, 2008, the Company adopted, on a prospective basis, SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective of the guidance is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. The adoption of SFAS 159 did not have a material impact on the Company’s consolidated financial statements since the Company did not elect to apply the fair value option for any of its eligible financial instruments or other items on the January 1, 2008 effective date.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51” (“SFAS 160”). SFAS 160 amends Accounting Research Bulletin No. 51, “Consolidated Financial Statements”, and requires all entities to report noncontrolling interests in subsidiaries within equity in the consolidated financial statements, but separate from the parent shareholders’ equity. SFAS 160 also requires any acquisitions or dispositions of noncontrolling interests that do not result in a change of control to be accounted for as equity transactions. In addition, SFAS 160 requires that a parent company recognize a gain or loss in net income when a subsidiary is deconsolidated upon a change in control. SFAS 160 applies to our fiscal year beginning on January 1, 2009 and will be adopted prospectively. The presentation and disclosure requirements shall be applied retrospectively for all periods presented. Early adoption is prohibited. The adoption of SFAS 160 will result in a reclassification of minority interest to a separate component of total equity and net income allocable to noncontrolling interest will no longer be treated as a reduction to net income but will be shown as a reduction from net income in calculating net income available to common shareholders. The adoption of SFAS 160 is not expected to have an impact on net income allocable to common shareholders or net income per common share.

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

Forward-Looking Statements: Forward-looking statements are made throughout this Quarterly Report on Form 10-Q. For this purpose, any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words “may,” “believes,” “anticipates,” “plans,” expects,” “seeks,” “estimates,” “intends,” and similar expressions are intended to identify forward-looking statements. There are a number of important factors that could cause the results of the Company to differ materially from those indicated by such forward-looking statements, including those detailed under the heading “Item 1A. Risk Factors” in Part II of this quarterly report on Form 10-Q. In light of the significant uncertainties inherent in the forward-looking statements included herein, the inclusion of such information should not be regarded as a representation by us or any other person that our objectives and plans will be achieved. Moreover, we assume no obligation to update these forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements.

Overview

The Company owns and operates approximately 19.6 million rentable square feet of flex, industrial and office properties located in eight states.

The Company focuses on increasing profitability and cash flow aimed at maximizing shareholder value. The Company strives to maintain high occupancy levels while increasing rental rates when market conditions allow. The Company also acquires properties which it believes will create long-term value, and disposes of properties which no longer fit within the Company’s strategic objectives or in situations where the Company believes it can optimize cash proceeds. Operating results are driven by income from rental operations and are therefore substantially influenced by rental demand for space within our properties.

During the first nine months of 2008, the Company successfully leased or re-leased 4.1 million square feet of space while experiencing a modest decrease in rental rates. Total net operating income for the nine months ended September 30, 2008 increased $6.7 million or 4.9% compared to the nine months ended September 30, 2007. See further discussion of operating results below.

Critical Accounting Policies and Estimates:

Our accounting policies are described in Note 2 to the consolidated financial statements included in this Form 10-Q. We believe our most critical accounting policies relate to revenue recognition, allowance for doubtful accounts, impairment of long-lived assets, depreciation, accruals of operating expenses and accruals for contingencies, each of which we discuss below.

Revenue Recognition: We recognize revenue in accordance with Staff Accounting Bulletin No. 104 of the Securities and Exchange Commission, Revenue Recognition in Financial Statements (“SAB 104”), as amended. SAB 104 requires that the following four basic criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; the delivery has occurred or services rendered; the fee is fixed or determinable; and collectibility is reasonably assured. All leases are classified as operating leases. Rental income is recognized on a straight-line basis over the terms of the leases. Straight-line rent is recognized for all tenants with contractual increases in rent that are not included on the Company’s credit watch list. Deferred rent receivable represents rental revenue recognized on a straight-line basis in excess of billed rents. Reimbursements from tenants for real estate taxes and other recoverable operating expenses are recognized as rental income in the period the applicable costs are incurred.

Property Acquisitions: In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 141, “Business Combinations,” we allocate the purchase price of acquired properties to land, buildings and equipment and identified tangible and intangible assets and liabilities associated with in-place leases (including tenant improvements, unamortized lease commissions, value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any) based on their respective estimated fair values.

In determining the fair value of the tangible assets of the acquired properties, management considers the value of the properties as if vacant as of the acquisition date. Management must make significant assumptions in determining the value of assets acquired and liabilities assumed. Using different assumptions in the allocation of the purchase cost of the acquired properties would affect the timing of recognition of the related revenue and expenses. Amounts allocated to land are derived from comparable sales of land within the same region. Amounts allocated to buildings and improvements, tenant improvements and unamortized lease commissions are based on current market replacement costs and other market rate information.

The value allocable to the above-market or below-market in-place lease values of acquired properties is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual rents to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The amounts allocated to above-market or below-market leases are included in other assets or other liabilities in the accompanying consolidated balance sheets and are amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases.

Allowance for Doubtful Accounts: Rental revenue from our tenants is our principal source of revenue. We monitor the collectibility of our receivable balances including the deferred rent receivable on an ongoing basis. Based on these reviews, we maintain an allowance for doubtful accounts for estimated losses resulting from the possible inability of our tenants to make required rent payments to us. Tenant receivables and deferred rent receivables are carried net of the allowances for uncollectible tenant receivables and deferred rent. As discussed below, determination of the adequacy of these allowances requires significant judgments and estimates. Our estimate of the required allowance is subject to revision as the factors discussed below change and is sensitive to the effect of economic and market conditions on our tenants.

Tenant receivables consist primarily of amounts due for contractual lease payments, reimbursements of common area maintenance expenses, property taxes and other expenses recoverable from tenants. Determination of the adequacy of the allowance for uncollectible current tenant receivables is performed using a methodology that incorporates specific identification, aging analysis, an overall evaluation of the historical loss trends and the current economic and business environment. The specific identification methodology relies on factors such as the age and nature of the receivables, the payment history and financial condition of the tenant, the assessment of the tenant’s ability to meet its lease obligations, and the status of negotiations of any disputes with the tenant. The allowance also includes a reserve based on historical loss trends not associated with any specific tenant. This reserve as well as the specific identification reserve is reevaluated quarterly based on economic conditions and the current business environment.

Deferred rent receivable represents the amount that the cumulative straight-line rental income recorded to date exceeds cash rents billed to date under the lease agreement. Given the long-term nature of these types of receivables, determination of the adequacy of the allowance for unbilled deferred rent receivable is based primarily on historical loss experience. Management evaluates the allowance for unbilled deferred rent receivable using a specific identification methodology for significant tenants designed to assess their financial condition and ability to meet their lease obligations.

Impairment of Long-Lived Assets: The Company evaluates a property for potential impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. On a quarterly basis, we evaluate our whole portfolio for impairment based on current operating information. In the event that these periodic assessments reflect that the carrying amount of a property exceeds the sum of the undiscounted cash flows (excluding interest) that are expected to result from the use and eventual disposition of the property, the Company would recognize an impairment loss to the extent the carrying amount exceeded the estimated fair value of the property. The estimation of expected future net cash flows is inherently uncertain and relies on subjective assumptions dependent upon future and current market conditions and events that affect the ultimate value of the property. Management must make assumptions related to the property such as future rental rates, tenant allowances, operating expenditures, property taxes, capital improvements, occupancy levels and the estimated proceeds generated from the future sale of the property. These assumptions could differ materially from actual results in future periods. Since SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” provides that the future cash flows used in this analysis be considered on an undiscounted basis, our intent to hold properties over the long-term directly decreases the likelihood of recording an impairment loss. If our strategy changes or if market conditions otherwise dictate an earlier sale date, an impairment loss could be recognized, and such loss could be material.

Depreciation: We compute depreciation on our buildings and equipment using the straight-line method based on estimated useful lives of generally 30 and five years, respectively. A significant portion of the acquisition cost of each property is allocated to building and building components. The allocation of the acquisition cost to building and building components, as well as the determination of their useful lives are based on estimates. If we do not appropriately allocate to these components or we incorrectly estimate the useful lives of these components, our computation of depreciation expense may not appropriately reflect the actual impact of these costs over future periods, which will affect net income. In addition, the net book value of real estate assets could be overstated or understated. The statement of cash flows, however, would not be affected.

Accruals of Operating Expenses: The Company accrues for property tax expenses, performance bonuses and other operating expenses each quarter based on historical trends and anticipated disbursements. If these estimates are incorrect, the timing and amount of expense recognized will be affected.

Accruals for Contingencies: The Company is exposed to business and legal liability risks with respect to events that may have occurred, but in accordance with U.S. generally accepted accounting principles (“GAAP”) has not accrued for such potential liabilities because the loss is either not probable or not estimable. Future events and the result of pending litigation could result in such potential losses becoming probable and estimable, which could have a material adverse impact on our financial condition or results of operations.

Effect of Economic Conditions on the Company’s Operations:

During the first nine months of 2008, the weakening economic conditions were reflected in commercial real estate as the Company experienced a decrease in new rental rates over expiring rents. It is uncertain what impact a recession or similar economic conditions may have on the Company’s ability to maintain high occupancy levels and increase rents. While the Company has not experienced a significant impact from the slowed economy, conditions may change and the Company may be impacted by lower occupancy and a reduced ability to raise rents.

While the Company historically has experienced a low level of write-offs due to bankruptcy, there is inherent uncertainty in a tenant’s ability to continue paying rent when in bankruptcy. As of September 30, 2008, the Company had approximately 18,000 square feet occupied by tenants that are protected by Chapter 11 of the U.S. Bankruptcy Code. Given the historical uncertainty of these tenants’ ability to meet their lease obligations, we will continue to reserve any income that would have been realized on a straight-line basis. Several other tenants have contacted us, requesting early termination of their lease, reduction in space under lease, rent deferment or abatement. At this time, the Company cannot anticipate what impact, if any, the ultimate outcome of these discussions will have on our operating results.

Company Performance and Effect of Economic Conditions on Primary Markets:

The Company’s operations are substantially concentrated in 10 regions. Current market conditions for each region are summarized below. During the nine months ended September 30, 2008, rental rates on new and renewed leases within the Company’s overall portfolio decreased 0.1% over expiring rents. Excluding a 45,000 square foot lease executed during the third quarter of 2008 on a space in Northern California, rental rates on new and renewed leases would have increased 1.5%. The Company has compiled the market occupancy information set forth below using third party reports for each respective market. The Company considers these sources to be reliable, but there can be no assurance that the information in these reports is accurate.

The Company owns approximately 4.0 million square feet in Southern California. Market vacancies have increased primarily due to the number of sub-prime lenders, mortgage brokers and other related businesses that have vacated office space, creating significantly more competition for tenants. These vacancies have had less of an impact on flex space, which comprises approximately 63.7% of the Company’s Southern California portfolio. Vacancy rates in Southern California range from 2.5% to 15.9%. The Company’s vacancy rate in this region at September 30, 2008 was 7.2%. For the nine months ended September 30, 2008, the overall market experienced negative net absorption of 0.4% attributed to the mortgage and housing-related companies as well as newly constructed space completed during 2008. The Company’s weighted average occupancy for the region decreased from 94.8% for the first nine months in 2007 to 93.5% for the first nine months in 2008. Annualized realized rent per square foot increased 2.6% from $16.98 per square foot for the first nine months in 2007 to $17.42 per square foot for the first nine months in 2008. Although these markets continue to experience increasing rental rates, the Company has seen signs of easing rental rate growth and modestly increasing concessions due to higher vacancies in the office market. Additionally, construction of Class A buildings, primarily in Orange County, could have an impact on the Company’s ability to maintain occupancy and generate rental rate growth within the office portfolio.

The Company owns approximately 1.8 million square feet in Northern California with concentrations in Sacramento, the East Bay (Hayward and San Ramon) and Silicon Valley (San Jose). Vacancy rates in these submarkets are 16.9%, 20.7% and 14.3%, respectively. The Company’s vacancy rate in its Northern California portfolio at September 30, 2008 was 8.6%. Demand in these submarkets has slowed measurably in the second half of 2008. Lease renewals and short term leases were the most common leasing activity in the market during this quarter as firms are seeking ways of reducing costs and curbing expansion. For the nine months ended September 30, 2008, the combined submarkets experienced positive net absorption of 0.6%, however, the time necessary to execute a transaction has lengthened as tenants weigh their options and negotiate on concessions. The Company’s weighted average occupancy in this region increased from 90.7% for the first nine months in 2007 to 92.3% for the first nine months in 2008. Annualized realized rent per square foot increased 3.3% from $13.81 per square foot for the first nine months in 2007 to $14.27 per square foot for the first nine months in 2008.

The Company owns approximately 1.2 million square feet in Southern Texas, specifically in the Austin and Houston markets. Market vacancy rates are 11.0% in the Austin market and 11.8% in the Houston market. The Company’s vacancy rate for these combined markets at September 30, 2008 was 6.9%. During the first half of 2008, job growth in both the Austin and Houston markets along with the strong oil and gas industry in the Houston market have increased leasing activity. However, during the third quarter of 2008 demand has softened in these markets as evidenced by increased tenant incentives such as free rent or higher improvement allowances. For the nine months ended September 30, 2008, the combined markets experienced positive net absorption of 0.7%. The Company’s weighted average occupancy in this region decreased from 95.3% for the first nine months in 2007 to 95.0% for the first nine months in 2008. Annualized realized rent per square foot increased 4.5% from $10.82 per square foot for the first nine months in 2007 to $11.31 per square foot for the first nine months in 2008. Texas leads the nation in scheduled construction projects, and as construction outweighs demand, it could have an impact on the Company’s ability to maintain occupancy and generate rental rate growth within the Company’s portfolio.

The Company owns approximately 1.7 million square feet in Northern Texas, primarily located in the Dallas Metroplex market. The market vacancy rate in Las Colinas, where a significant concentration of the Company’s properties are located, is 10.6%. The Company’s vacancy rate at September 30, 2008 in this market was 6.8%. For the nine months ended September 30, 2008, the market experienced positive net absorption of 0.8% as the result of continued job growth. During 2008, modest new construction continued, which included both speculative construction, as well as owner-user construction. Despite the new construction, the Company has experienced a modest level of leasing activity during the first nine months of 2008 generating rental rate growth and higher occupancy. The Company’s weighted average occupancy for the region increased from 86.7% for the first nine months in 2007 to 92.9% for the first nine months in 2008. Annualized realized rent per square foot increased 3.4% from $10.34 per square foot for the first nine months in 2007 to $10.69 per square foot for the first nine months in 2008 as rental rates have increased modestly over expiring leases. However, new construction completed during the year could have an impact on the Company’s ability to maintain occupancy and generate rental rate growth within the Company’s portfolio.

The Company owns approximately 3.6 million square feet in South Florida. The Company owns Miami International Commerce Center (“MICC”) located in the Airport West submarket of Miami-Dade County. While the saturation of the condominium and housing markets in Miami has negatively impacted its overall economy, it has had little impact on international trade-based assets, such as industrial and flex space, which constitutes the majority of the Company’s South Florida portfolio. MICC is located less than one mile from the cargo entrance of the Miami International Airport, which is one of the most active ports in the United States. The Company acquired two assets in Palm Beach County at the end of 2006, comprising 398,000 square feet. The downturn in the housing market and slowing economy have adversely affected Palm Beach County. Market vacancy rates for Miami-Dade County and Palm Beach County are 6.9% and 8.4%, respectively, compared with the Company’s South Florida vacancy rate of 3.9% at September 30, 2008. For the nine months ended September 30, 2008, the combined markets experienced negative net absorption of 0.4%. The Company’s weighted average occupancy in this region outperformed the market and remained strong, decreasing slightly from 97.0% for the first nine months in 2007 to 96.8% for the first nine months in 2008. Annualized realized rent per square foot increased 5.4% from $8.82 per square foot for the first nine months in 2007 to $9.30 per square foot for the first nine months in 2008.

The Company owns approximately 3.0 million square feet in the Northern Virginia submarket of Washington D.C., where the average market vacancy rate is 12.3%. Vacancy rates in this market increased as new supply continues to outpace the demand coupled with tenants downsizing their existing space. Despite the increase in the market’s vacancy rate, the Company’s vacancy rate at September 30, 2008 was 2.7%. For the nine months ended September 30, 2008, the market experienced positive net absorption of 1.0%. The increase in sublease space and decrease in demand has lengthened the time of lease negotiation as tenants weigh their options and negotiate on tenant improvements. Higher concessions are more prevalent as landlords entice prospective tenants, while they struggle to keep rents steady. These factors could limit the Company’s ability to generate rental rate growth and place pressure on occupancy. The Company’s annualized realized rent per square foot increased 3.4% from $19.43 per square foot for the first nine months in 2007 to $20.10 per square foot for the first nine months in 2008. The Company’s weighted average occupancy increased from 94.9% for the first nine months in 2007 to 97.5% for the first nine months in 2008.

The Company owns approximately 1.8 million square feet in the Maryland submarket of Washington D.C. The Company’s vacancy rate in the region at September 30, 2008 was 7.4% compared to 11.8% for the market as a whole. The market vacancy rate increased as new developments are completed with limited preleasing activities combined with more companies contracting and reorganizing business operations. Rather than dropping rental rates, landlords are offering higher concessions to prospective tenants. For the nine months ended September 30, 2008, the market experienced negative net absorption of 0.4%, which is attributed to a decrease in demand for large blocks of space due to the slowing economy. The Company’s weighted average occupancy decreased from 94.5% for the first nine months in 2007 to 92.5% for the first nine months in 2008, modestly outperforming the market. The decrease in occupancy was primarily related to a 67,000 square foot tenant vacating its space at the end of 2007. Annualized realized rent per square foot increased 0.5% from $23.18 per square foot for the first nine months in 2007 to $23.29 per square foot for the first nine months in 2008.

The Company owns approximately 1.3 million square feet in the Beaverton submarket of Portland, Oregon. The market vacancy rate in this region is 18.6%. The Company’s vacancy rate in the market was 15.8% at September 30, 2008. Recent economic trends and slowdown have resulted in increases in both vacancy rates and rent concessions in the market. For the nine months ended September 30, 2008, the market experienced negative net absorption of 3.3%. The Company’s weighted average occupancy decreased from 86.9% for the first nine months in 2007 to 84.0% for the first nine months in 2008 primarily related to a 120,000 square foot tenant vacating its space during the second quarter of 2008. Despite the recent trends and slowdown, annualized realized rent per square foot increased 6.5% from $15.76 per square foot for the first nine months in 2007 to $16.79 per square foot for the first nine months in 2008. The increase was primarily the result of the impact from write-offs related to business failures during the nine months ended September 30, 2007.

The Company owns approximately 679,000 square feet in the Phoenix and Tempe submarkets of Arizona. Market vacancies increased significantly due in part to the number of housing-related tenants who have vacated space combined with companies contracting and reorganizing business operations, creating significantly more competition for tenants. During 2007 and continuing into 2008, significant construction of buildings has impacted the Company’s portfolio and may result in higher lease concessions while limiting the Company’s ability to generate rental rate growth. The market vacancy rate is 11.5% compared to the Company’s vacancy rate of 13.6% at September 30, 2008. For the nine months ended September 30, 2008, despite the decrease in demand, the market experienced positive net absorption of 0.6%. Although demand for space has subsided, annualized realized rent per square foot increased 3.9% from $11.40 per square foot for the first nine months in 2007 to $11.85 per square foot for the first nine months in 2008. The Company’s weighted average occupancy in the region decreased from 87.3% for the first nine months in 2007 to 86.8% for the first nine months in 2008.

The Company owns approximately 521,000 square feet in the state of Washington. On February 16, 2007, the Company acquired Overlake Business Center, a 493,000 square foot multi-tenant office and flex business park located in Redmond, Washington. The technology industry continues to drive the market. The market experienced positive net absorption of 1.2% for the nine months ended September 30, 2008. The Company’s vacancy rate in this region at September 30, 2008 was 6.5% compared to 8.5% for the market as a whole. The Company’s weighted average occupancy increased from 88.8% for the first nine months in 2007 to 94.7% for the first nine months in 2008. Annualized realized rent per square foot increased 9.5% from $17.52 per square foot for the first nine months in 2007 to $19.18 per square foot for the first nine months in 2008.

Growth of the Company’s Operations and Acquisitions and Dispositions of Properties:

The Company is focused on maximizing cash flow from its existing portfolio of properties by expanding its presence in existing and new markets through strategic acquisitions and the disposition of non-strategic assets. The Company has historically maintained a low-leverage-level approach intended to provide the Company with the flexibility for future growth.

In 2007, the Company acquired 870,000 square feet for an aggregate cost of $140.6 million. The Company acquired Overlake Business Center, a 493,000 square foot multi-tenant office and flex business park located in Redmond, Washington, for $76.0 million; Commerce Campus, a 252,000 square foot multi-tenant office and flex business park located in Santa Clara, California, for $39.2 million; and Fair Oaks Corporate Center, a 125,000 square foot multi-tenant office park located in Fairfax, Virginia, for $25.4 million.

Scheduled Lease Expirations:

In addition to the 1.3 million square feet, or 6.7%, of currently available space in our total portfolio, leases representing approximately 4.6% of the leased square footage of our total portfolio are scheduled to expire during the remainder of 2008. Leases comprising approximately 203,000 square feet of currently vacant space have been executed as of the date of this report and are expected to commence during the fourth quarter of 2008 and first quarter of 2009. Our ability to re-lease available space depends upon the market conditions in the specific submarkets in which our properties are located.

Impact of Inflation:

Although inflation has not been significant in recent years, it remains a factor in our economy, and the Company continues to seek ways to mitigate its potential impact. A substantial portion of the Company’s leases require tenants to pay operating expenses, including real estate taxes, utilities, and insurance, as well as increases in common area expenses, partially reducing the Company’s exposure to inflation. During 2007 and 2008, the Company experienced modest increases in certain operating costs, including repairs and maintenance, property insurance and utility costs affecting the Company’s overall profit margin.

Concentration of Portfolio by Region:

Rental income, cost of operations and rental income less cost of operations, excluding depreciation and amortization, or net operating income prior to depreciation and amortization (defined as “NOI” for purposes of the following tables), are summarized for the three and nine months ended September 30, 2008 by major geographic region below. The Company uses NOI and its components as a measurement of the performance of its commercial real estate. Management believes that these financial measures provide them as well as the investor the most consistent measurement on a comparative basis of the performance of the commercial real estate and its contribution to the value of the Company. Depreciation and amortization has been excluded from these financial measures as they are generally not used in determining the value of commercial real estate by management or the investment community. Depreciation and amortization is generally not used in determining value as they consider the historical costs of an asset compared to its current value; therefore, to understand the effect of the assets’ historical cost on the Company’s results, investors should look at GAAP financial measures, such as total operating costs including depreciation and amortization. The Company’s calculation of NOI may not be comparable to those of other companies and should not be used as an alternative to measures of performance calculated in accordance with GAAP. The tables below reflect rental income, operating expenses and NOI for the three and nine months ended September 30, 2008 based on geographical concentration. The total of all regions is equal to the amount of rental income and cost of operations recorded by the Company in accordance with GAAP. As part of the tables below, we have shown the effect of depreciation and amortization on NOI. We have reconciled NOI to income before minority interests in the table under “Results of Operations” below. The percent of total by region reflects the actual contribution to rental income, cost of operations and NOI during the period (in thousands):

Comparative Analysis of the Three and Nine Months Ended September 30, 2008 to the Three and Nine Months Ended September 30, 2007

Results of Operations: In order to evaluate the performance of the Company’s overall portfolio over two comparable periods, management analyzes the operating performance of a consistent group of properties owned and operated throughout both periods (herein referred to as “Same Park”). Operating properties that the Company acquired subsequent to January 1, 2007 are referred to as “Non-Same Park.” For the nine months ended September 30, 2008 and 2007, the Same Park facilities constitute 18.7 million rentable square feet, which includes all assets the Company owned and operated from January 1, 2007 through September 30, 2008, representing approximately 95.5% of the total square footage of the Company’s portfolio as of September 30, 2008.

Rental income, cost of operations and rental income less cost of operations, excluding depreciation and amortization or net operating income prior to depreciation and amortization (defined as “NOI” for purposes of the following table) are summarized for the three and nine months ended September 30, 2008 and 2007. The Company’s property operations account for substantially all of the net operating income earned by the Company. See “Concentration of Portfolio by Region” above for more information on NOI, including why the Company presents NOI and how the Company uses NOI. The Company’s calculation of NOI may not be comparable to those of other companies and should not be used as an alternative to measures of performance calculated in accordance with GAAP.

The following table presents the operating results of the Company’s properties for the three and nine months ended September 30, 2008 and 2007 in addition to other income and expense items affecting income from operations. The Company breaks out Same Park operations to provide information regarding trends for properties the Company has held for the periods being compared (in thousands, except per square foot data):
