EXPLANATORY NOTE

This Amendment No. 1 on Form 10-Q/A (the “Amended Filing”) of Kilroy Realty Corporation (the “Company”) for the quarterly period ended March 31, 2005 (the “Original Filing”) is being filed to restate the Company’s income from continuing operations per common share included within its consolidated statements of operations for the three months ended March 31, 2005 and 2004 and the notes related thereto, to correctly reflect the impact of preferred stock dividends in the calculation of income from continuing operations per common share in accordance with Statement of Financial Accounting Standards No. 128, “Earnings per Share,” so that income from continuing operations per share is presented net of preferred dividends paid and accrued. As originally filed, the quarterly reports for the three months ended March 31, 2005 and 2004 incorrectly reflected income from continuing operations per common share before deducting the dividends paid and accrued. The calculation error had no impact on income from continuing operations, net income, net income per share, the Company’s consolidated balance sheets, consolidated statement of stockholders’ equity and consolidated statements of cash flows, or the calculation of funds from operations. The only line items required to be restated to correct this calculation error are the per share amounts for income from continuing operations, basic and diluted, included within the consolidated statements of operations. The Amended Filing is also being filed to restate the consolidated statements of cash flows for the three months ended March 31, 2005 and 2004. As originally filed, two items in the consolidated statements of cash flows were incorrectly classified. First, distributions to cumulative redeemable preferred unitholders were included in the Company’s consolidated statements of cash flows as an operating activity and should have been classified as a financing activity. Second, capital expenditures for operating properties, development and redevelopment projects and undeveloped land were reflected on an accrual basis of accounting rather than the cash paid for such expenditures in investing activities in the consolidated statements of cash flows. The adjustment to reflect these expenditures on a cash basis in investing activities for each period is offset by an adjustment for the same amount in cash flows from operating activities to appropriately reflect the associated increases and decreases in accounts payable, accrued expenses and other liabilities. These reclassifications do not affect the total net change in cash and cash equivalents and have no impact on the Company’s consolidated balance sheets, consolidated statements of operations and consolidated statement of stockholders’ equity. For a more detailed description of the restatements, see Note 14 to the accompanying consolidated financial statements contained in this Form 10-Q/A. In connection with the restatements, the Company reevaluated the effectiveness of its controls and procedures and, accordingly, includes revised disclosure in this Amendment No. 1 on Form 10-Q/A under Part I, Item 4—Controls and Procedures.

The Company is concurrently filing amendments to its Annual Report on Form 10-K/A for the fiscal year ended December 31, 2004 and its Quarterly Report on Form 10-Q/A for the quarter ended September 30, 2004 also to restate the Company’s income from continuing operations per common share included within its consolidated statements of operations and the consolidated statements of cash flows for the same reclassifications noted above. The decision to restate the Company’s consolidated financial statements was previously announced in our Current Reports on Form 8-K filed with the Securities and Exchange Commission on July 21, 2005 and August 9, 2005.

The Company has also updated its historical financial statements in this Form 10-Q/A for discontinued operations that have resulted from the classification of a property as held for sale as of June 30, 2005 in accordance with Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS 144”). This SFAS 144 treatment had no effect on the net income available to common stockholders or the Company’s financial condition. The other concurrently filed amendments referenced above reflect similar updates.

To reflect the restatements of the consolidated statements of cash flows for the reclassifications described above and the update for discontinued operations, the Company is also re-issuing the Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) that accompanied the financial statements in the Original Filing.

This Form 10-Q/A does not reflect events occurring after the filing of the Original Filing or modify or update disclosures, including the exhibits to the Original Filing, affected by subsequent events except in connection with the foregoing.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Three Months Ended March 31, 2005 and 2004

(unaudited)

1. Organization and Basis of Presentation

Organization

Kilroy Realty Corporation (the “Company”) owns, operates and develops office and industrial real estate, primarily in Southern California. The Company operates as a self-administered real estate investment trust (“REIT”). As of March 31, 2005, the Company’s stabilized portfolio of operating properties consisted of 82 office buildings (the “Office Properties”) and 48 industrial buildings (the “Industrial Properties”), which encompassed an aggregate of approximately 7.6 million and 4.5 million rentable square feet, respectively, and was 94.1% occupied. The Company’s stabilized portfolio of operating properties consists of all of the Office Properties and Industrial Properties and excludes properties currently under construction or “lease-up” properties.

The Company defines “lease-up” properties as properties recently developed or redeveloped by the Company that have not yet reached 95% occupancy and are within one year following substantial completion. Lease-up properties are reclassified to land and improvements and building and improvements from construction in progress on the consolidated balance sheets upon building shell completion. As of March 31, 2005 the Company had one redevelopment property encompassing approximately 241,600 rentable square feet, which was in the lease-up phase. In addition, as of March 31, 2005 the Company had two development properties under construction, which when completed are expected to encompass approximately 103,300 rentable square feet.

The Company owns its interests in all of its properties through Kilroy Realty, L.P. (the “Operating Partnership”) and Kilroy Realty Finance Partnership, L.P. (the “Finance Partnership”) and conducts substantially all of its operations through the Operating Partnership. The Company owned an 88.6% general partnership interest in the Operating Partnership as of March 31, 2005. Kilroy Realty Finance, Inc., a wholly-owned subsidiary of the Company, is the sole general partner of the Finance Partnership and owns a 1.0% general partnership interest. The Operating Partnership owns the remaining 99.0% limited partnership interest of the Finance Partnership. The Company conducts substantially all of its development services through Kilroy Services, LLC (“KSLLC”), which is a wholly-owned subsidiary of the Operating Partnership. Unless otherwise indicated, all references to the Company include the Operating Partnership, the Finance Partnership, KSLLC and all wholly-owned subsidiaries of the Company.

Basis of Presentation

The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, the Finance Partnership, KSLLC and all wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements.

Net income after preferred distributions is allocated to the common limited partners of the Operating Partnership (“Minority Interest of the Operating Partnership”) based on their ownership percentage of the Operating Partnership. The common limited partner ownership percentage is determined by dividing the number of common units held by the Minority Interest of the Operating Partnership by the total common units outstanding. The issuance of additional shares of common stock or common units results in changes to the Minority Interest of the Operating Partnership percentage as well as the total net assets of the Company. As a result, all capital transactions result in an allocation between stockholders’ equity and the minority interest held by common unitholders of the Operating Partnership in the accompanying consolidated balance sheets to account for the change in the Minority Interest of the Operating Partnership ownership percentage as well as the change in total net assets of the Company.

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The accompanying interim financial statements have been prepared by the Company’s management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature which are considered necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ended December 31, 2005. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2004, as amended.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period’s presentation. The Company reclassified the change in restricted cash in the consolidated statements of cash flows from a financing activity to an investing activity for all periods presented.

Recent Accounting Pronouncements

In December 2004, the FASB issued Statement 123 (revised), “Share-Based Payment” (“FAS 123(R)”). FAS 123(R) requires that all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. The new standard will be effective as of the beginning of the first fiscal year beginning after June 15, 2005. The adoption of this statement is not expected to have a material effect on the Company’s results of operations or financial condition.

Stock Option Accounting

Effective January 1, 2002, the Company voluntarily adopted the fair value recognition provisions of SFAS 123, “Accounting for Stock-Based Compensation” (“SFAS 123”) prospectively, for all employee stock option awards granted or settled after January 1, 2002. Under the fair value recognition provisions of SFAS 123, total compensation expense related to stock options is determined using the fair value of the stock options on the date of grant. Total compensation expense is then recognized on a straight-line basis over the option vesting period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Prior to 2002, the Company accounted for stock options issued under the recognition and measurement provisions of APB Opinion 25 “Accounting for Stock Issued to Employees and Related Interpretations.” The following table illustrates the effect on net income and earnings per share if the fair value based method had been applied to all outstanding and unvested awards in each period.

2. Dispositions

Dispositions

During the three months ended March 31, 2005, the Company sold the following properties:

Address / City	Property Type	Month of Disposition	Number of Buildings	Rentable Square Feet
2501 Pullman/1700 Carnegie Santa Ana, CA	Office	March	2	128,266

5115 North 27th Avenue Phoenix, AZ	Industrial	March	1	130,877
Total			4	305,186

These properties were sold through a portfolio transaction for an aggregate gross sales price of $38.7 million. The Company recorded a net gain of approximately $5.8 million in connection with the disposition. The Company used the net cash proceeds from the sale of these properties to fund its development programs and to repay borrowings under the Credit Facility (defined in Note 4). The net income and the net gain on disposition for these properties have been included in discontinued operations for the three months ended March 31, 2005 and 2004 (see Note 10).

3. Redevelopment Projects

Stabilized Redevelopment Project

During the three months ended March 31, 2005, the Company added the following redevelopment project to the Company’s stabilized portfolio:

Address / Submarket / City	Property Type	Completion Date	Stabilization Date	Number of Buildings	Rentable Square Feet
5717 Pacific Center Blvd. Sorrento Mesa San Diego, CA	Office	Q1 2004	Q1 2005	1	68,000

4. Unsecured and Secured Debt

Unsecured Line of Credit

As of March 31, 2005, the Company had borrowings of $153.0 million outstanding under its revolving unsecured line of credit (the “Credit Facility”) and availability of approximately $272.0 million. The Credit Facility bears interest at an annual rate between LIBOR plus 1.00% and LIBOR plus 1.70% depending upon the Company’s leverage ratio at the time of borrowing (4.01% at March 31, 2005), and matures in October 2007 with an option to extend the maturity for one year. The fee for unused funds ranges from an annual rate of 0.20% to 0.30% depending on the Company’s leverage ratio. The Company expects to use the Credit Facility to finance development and redevelopment expenditures, to fund potential acquisitions and for other general corporate uses.

Debt Covenants and Restrictions

The Credit Facility, the unsecured senior notes and certain other secured debt arrangements contain covenants and restrictions requiring the Company to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum total debt to total assets ratio, a maximum total secured debt to total assets ratio, a minimum debt service coverage and fixed charge coverage ratios, minimum consolidated tangible net worth and a limit of development activities as compared to total assets. The Company was in compliance with all of its debt covenants at March 31, 2005.

Capitalized Interest and Loan Fees

Total interest and loan fees capitalized was $2.1 million for both the three months ended March 31, 2005 and 2004.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In January 2005, the Company’s interest-rate swap agreement to fix LIBOR on $50 million of its variable-rate debt at 4.46% expired. The instruments described above have been designated as cash flow hedges. As of March 31, 2005, the balance in accumulated other net comprehensive income (“AOCI”) was approximately $1.1 million relating to the net increase in the fair market value of the derivative instruments since their inception. For the three months ended March 31, 2005 and 2004, the Company did not record any gains or losses attributable to cash flow hedge ineffectiveness since the terms of the Company’s derivative contracts and debt obligations were and are expected to continue to be effectively matched. Amounts reported in AOCI will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt.

6. Minority Interests

Minority interests represent the common and preferred limited partnership interests in the Operating Partnership. The Company owned an 88.6% and 87.2% general partnership interest in the Operating Partnership as of March 31, 2005 and 2004.

During the three months ended March 31, 2005, 269,249 common limited partnership units of the Operating Partnership were redeemed for shares of the Company’s common stock on a one-for-one basis. Neither the Company nor the Operating Partnership received any proceeds from the issuance of the common stock for the redemption of the common limited partnership units.

7. Stockholders’ Equity and Employee Incentive Plans

In February 2005, the Company’s Compensation Committee granted an aggregate of 101,112 restricted shares of common stock to certain executive officers and key employees. Compensation expense for the restricted shares is calculated based on the closing price per share of $41.35 on the February 23, 2005 grant date and is amortized on a straight-line basis over the performance and vesting periods. Of the shares granted, 18,139 vest at the end of a one-year period, 61,812 vest in equal annual installments over a two-year period and 21,161 vest in equal annual installments over a five-year period. The Company recorded approximately $0.3 million in compensation expense related to these restricted stock grants during the three months ended March 31, 2005 and 2004.

In March 2003, the Company’s Compensation Committee approved a special long-term compensation program for the Company’s executive officers. The program provides for cash compensation to be earned at December 31, 2005 if the Company attains certain performance measures based on annualized total stockholder returns on an absolute and relative basis. The amount payable for the absolute component is based upon the amount by which the annualized total return to stockholders over the period exceeds 10%. The targets for the relative component require the Company to obtain an annualized total return to stockholders that is at or above the 70th percentile of annualized total return to stockholders achieved by members of a pre-defined peer group during the same three-year period, and includes additional incentives for annualized total return to stockholders that is at or above the 80th percentile. Compensation expense under this program is accounted for using variable plan accounting. The Company estimates the amount to be paid based on the average closing share price of the Company’s common stock as reported on the New York Stock Exchange (“NYSE”) for the last ten days of the period, and records compensation expense equal to that portion of the total compensation applicable to the portion of the performance period that has elapsed through the end of the period. Under the absolute portion of the plan, for every $1 change in the Company’s ten-day average closing stock price, the total payable over the three-year term of the plan changes by approximately $1.7 million. During the three months ended March 31, 2005 and 2004, the Company accrued approximately $1.7 million and $3.6 million, respectively, of compensation expense related to this plan, which is included in general and administrative expenses. The total amount accrued relating to the plan was $26.1 million as of March 31, 2005 which is included in accounts payable, accrued expenses and other liabilities.

During the three months ended March 31, 2005, the Company accepted the return, at the current quoted market price, of 41,119 shares of its common stock from certain key employees in accordance with the provisions of its incentive stock plan to satisfy minimum statutory tax-withholding requirements related to restricted shares that vested during this period.

8. Commitments and Contingencies

In January 2005, the Company paid $1.8 million pursuant to a court approved settlement agreement related to a lease termination that occurred in 2001. The amount was previously recorded as a charge to other property income during the third quarter of 2004.

9. Segment Disclosure

The Company’s reportable segments consist of the two types of commercial real estate properties for which management internally evaluates operating performance and financial results: Office Properties and Industrial Properties. The Company also has certain corporate level activities including legal administration, accounting, finance and management information systems, which are not considered separate operating segments.

The Company evaluates the performance of its segments based upon Net Operating Income. Net Operating Income is defined as operating revenues (rental income, tenant reimbursements and other property income) less property and related expenses (property expenses, real estate taxes, ground leases and provision for bad debts) and does not include interest and other income, interest expense, depreciation and amortization and corporate general and administrative expenses. There is no intersegment activity.

10. Discontinued Operations

In accordance with SFAS 144 “Accounting for the Impairment or Disposal of Long-Lived Assets,” the net income and the net gain or loss on dispositions of operating properties sold or classified as held for sale are reflected in the consolidated statements of operations as discontinued operations for all periods presented. For the three months ended March 31, 2005 and 2004, discontinued operations included the net income and the net gain on sale of three office buildings and one industrial building sold during the three months ended March 31, 2005 (see Note 2) and the one industrial property that was reported as held for sale as of June 30, 2005 (see Note 15). For the three months ended March 31, 2004, discontinued operations also included the net income, the impairment loss and net gain or loss on sale of one office property and one industrial property sold in 2004. The following table summarizes the income and expense components that comprise discontinued operations for the three months ended March 31:

11. Earnings Per Share (As Restated, see Note 14)

Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted earnings per share is computed by dividing net income by the sum of the weighted-average number of common shares outstanding for the period plus the number of common shares issuable assuming the exercise of all dilutive securities. The Company does not consider common units of the Operating Partnership to be dilutive since any issuance of shares of common stock upon the redemption of the common units would be on a one-for-one basis and would not have any effect on diluted earnings per share. The following table reconciles the numerator and denominator of the basic and diluted per-share computations for net income.

12. Comprehensive Income

Comprehensive income for the three months ended March 31, 2005 and 2004 consisted of net income plus changes in the fair market value of cash flow hedges that were properly not reflected in the consolidated statements of operations. The components of comprehensive income are as follows:

	Three Months Ended March 31,

13. Subsequent Events

On April 15, 2005, aggregate distributions of approximately $16.6 million were paid to common stockholders and common unitholders of record on March 31, 2005.

14. Restatements

Income from Continuing Operations per Common Share

Subsequent to the issuance of the Company’s quarterly consolidated financial statements for the three months ended March 31, 2005, the Company’s management determined that it incorrectly computed income from continuing operations per common share by not reflecting the impact of preferred stock dividends paid and accrued in respect of the Company’s preferred stock in accordance with Statement of Financial Accounting Standards No. 128, “Earnings per Share.” The calculation error had no impact on income from continuing operations, net income, net income per share, or the Company’s consolidated balance sheets, consolidated statement of stockholders’ equity and consolidated statements of cash flows. The only line items required to be restated to correct this calculation error are the per share amounts for income from continuing operations, basic and diluted, on the consolidated statements of operations. As a result, “Income from continuing operations per common share—basic and diluted” for the three months ended March 31, 2005 and 2004 included within the consolidated statements of operations and in Note 11 to the consolidated financial statements have been restated from the amounts previously reported.

Cash Flow Classifications

Also subsequent to the issuance of the Company’s quarterly consolidated financial statements for the three months ended March 31, 2005, the Company’s management concluded that it had been incorrectly classifying two items on the consolidated statements of cash flows. First, distributions to cumulative redeemable preferred unitholders were included in the Company’s consolidated statements of cash flows as an operating activity when, in accordance with Statement of Financial Accounting Standards No. 95 “Statement of Cash Flows”, distributions paid to cumulative redeemable preferred unitholders should have been classified as a financing activity. Second, capital expenditures for operating properties, development and redevelopment projects and undeveloped land were reflected on an accrual basis of accounting rather than the cash paid for such expenditures in investing activities in the consolidated statements of cash flows. The adjustment to reflect these expenditures on a cash basis in investing activities for each period is offset by an adjustment for the same amount in cash flows from operating activities to appropriately reflect the associated increases and decreases in accounts payable, accrued expenses and other liabilities. As a result, the net cash provided by (used in) operating activities, investing activities and financing activities for the three months ended March 31, 2005 and 2004 included in the consolidated statements of cash flows have been restated from the amounts previously reported. In addition, the Company reclassified the change in restricted cash in the consolidated statements of cash flows from a financing activity to an investing activity. These reclassifications do not affect the total net change in cash and cash equivalents and has no impact on the Company’s consolidated balance sheets, consolidated statements of operations and consolidated statement of stockholders’ equity.

In light of these risks, uncertainties and assumptions, the forward-looking events contained in this report may not occur.

Impact of Restatements and Reclassifications

Management’s Discussion and Analysis of Financial Condition and Results of Operations has been updated to reflect the restatements of the consolidated statements of cash flows and the reclassifications for discontinued operations. For a more detailed description of the restatements and reclassifications, see Notes 14 and 15 to the accompanying consolidated financial statements included in this Form 10-Q/A.

Overview and Background

Kilroy Realty Corporation (the “Company”) owns, operates, and develops office and industrial real estate, primarily in Southern California. The Company operates as a self-administered real estate investment trust (“REIT”). The Company owns its interests in all of its properties through Kilroy Realty, L.P. (the “Operating Partnership”) and Kilroy Realty Finance Partnership, L.P. (the “Finance Partnership”) and conducts substantially all of its operations through the Operating Partnership. The Company owned an 88.6% and 87.2% general partnership interest in the Operating Partnership as of March 31, 2005 and 2004, respectively.

Factors That May Influence Future Results of Operations

Rental income.    The amount of net rental income generated by the Company’s properties depends principally on its ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly developed or redeveloped properties and space available from unscheduled lease terminations. The amount of rental income generated by the Company also depends on its ability to maintain or increase rental rates in its submarkets. Negative trends in one or more of these factors could adversely affect the Company’s rental income in future periods.

Rental rates.    For leases that commenced during the three months ended March 31, 2005, the change in rental rate was an increase of 10.5% on a GAAP basis, and a decrease of 2.8% on a cash basis. The change in rental rate on a cash basis is calculated as the change between the initial stated rent for a new or renewed lease and the ending stated rent for the expiring lease for the same space, whereas the change in rental rate on a GAAP

20

basis compares the average rents over the term of the lease for each lease. Both calculations exclude leases for which the space was vacant longer than one year. Management believes that the average rental rates for its properties are approximately at the current average quoted market rates, although individual properties within any particular submarket presently may be leased above or below the current quoted market rates within that submarket. The Company cannot give any assurance that leases will be renewed or that available space will be re-leased at rental rates equal to or above the current quoted market rates.

Scheduled lease expirations.    In addition to the 705,500 square feet of currently available space in the Company’s stabilized portfolio, leases representing approximately 4.7% and 10.2% of the leased square footage of the Company’s stabilized portfolio are scheduled to expire during the remainder of 2005 and 2006, respectively. The leases scheduled to expire during the remainder of 2005 and the leases scheduled to expire in 2006 represent approximately 1.0 million square feet of office space, or 11.1% of the Company’s total annualized base rent, and 0.6 million square feet of industrial space, or 2.5% of the Company’s total annualized base rent, respectively. Management believes that the average rental rates for leases scheduled to expire during the remainder of 2005 are approximately at the current average quoted market rates. The Company’s ability to release available space depends upon the market conditions in the specific submarkets in which the Properties are located.

Submarket Information

Los Angeles County.    There have been modest signs of improvement in market conditions in the overall Los Angeles County region during the last two years based on third-party reports of positive absorption and decreased levels of direct vacancy as well as an increased level of interest in leasing opportunities at the Company’s properties. Most notable have been the improvements seen in the West Los Angeles and Long Beach submarkets. Conversely, the El Segundo submarket remains the Company’s most significant leasing challenge as management continues to see only mild signs of improvement in this region. At March 31, 2005, the Company’s Los Angeles stabilized office portfolio was 94% occupied with approximately 170,500 vacant rentable square feet as compared to 91% occupied with approximately 257,100 vacant rentable square feet at December 31, 2004. As of March 31, 2005, leases representing an aggregate of approximately 118,000 and 367,500 rentable square feet are scheduled to expire during the remainder of 2005 and 2006, respectively, in this region.

The Los Angeles stabilized portfolio includes an office building that was developed by the Company that has not yet reached stabilized occupancy. The building, which is located in a two-building office complex in the El Segundo submarket, was added to the stabilized portfolio in 2003 since one year had passed following substantial completion. This building encompasses approximately 133,300 rentable square feet and was approximately 56% occupied as of March 31, 2005 compared to 37% as of December 31, 2004. The Company is currently in lease negotiations on an additional 38,000 square feet of space in this building, which, if executed, will increase occupancy to 84% from 56% as of March 31, 2005. Within the same complex in El Segundo, the Company has one office redevelopment project encompassing approximately 241,600 rentable square feet. This project was in the lease-up phase and was 19% leased as of March 31, 2005.

San Diego County.    San Diego County remains one of the strongest markets in Southern California real estate based on third-party reports of positive absorption, increased rental rates and growing tenant demand. The Company continues to expand its presence in this market by aggressively seeking development opportunities in the region. In March 2005, the Company committed to develop a four-building office complex, which when complete will encompass an aggregate of approximately 466,000 rentable square feet. The Company has pre-leased three of the four buildings, or 78% of the rentable square feet, to a single tenant. See additional information under the caption “—Recent Information Regarding Significant Tenants—Intuit, Inc.” The Company also commenced construction on the third phase of a development project in July 2004, which when complete will encompass an aggregate of approximately 103,000 rentable square feet. This development project was not leased as of March 31, 2005. See additional information regarding the Company’s development projects under the caption “—Development and redevelopment programs.”

21

As of March 31, 2005, the Company’s San Diego stabilized office portfolio was 94% occupied with approximately 204,000 vacant rentable square feet compared to 97% occupied with approximately 102,300 vacant rentable square feet as of December 31, 2004. The decrease in occupancy is primarily attributable to one redevelopment project, encompassing approximately 68,000 rentable square feet, that was previously in the lease-up phase and was added to the stabilized portfolio during the first quarter of 2005 since one year had passed following substantial completion. This project has not been leased as of March 31, 2005. Leases representing an aggregate of approximately 130,000 and 210,000 rentable square feet are scheduled to expire during the remainder of 2005 and 2006, respectively in this region.

Orange County.    As of March 31, 2005, the Company’s Orange County properties were 98% occupied with approximately 73,100 vacant rentable square feet. As of March 31, 2005, leases representing an aggregate of approximately 217,000 and 358,700 rentable square feet were scheduled to expire during the remainder of 2005 and 2006, respectively, in this region.

Sublease space.    Of the Company’s leased space at March 31, 2005, approximately 420,300 rentable square feet, or 3.5%, of the square footage in the Company’s stabilized portfolio was available for sublease, as compared to 435,200 rentable square feet, or 3.5% at December 31, 2004. Of the 3.5% of available sublease space in the Company’s stabilized portfolio as of March 31, 2005, approximately 2.9% was vacant space and the remaining 0.6% was occupied. Approximately 74% of the available sublease space as of March 31, 2005 is located in the Orange County submarket. Of the approximately 420,300 rentable square feet available for sublease at March 31, 2005, approximately 18,200 and 2,500 rentable square feet represents leases scheduled to expire during the remainder of 2005 and 2006, respectively.

Negative trends or other events that impair the Company’s ability to renew or release space and its ability to maintain or increase rental rates in its submarkets could have an adverse effect on the Company’s future financial condition, results of operations and cash flows.

Recent Information Regarding Significant Tenants

The Boeing Company. As of March 31, 2005, the Company’s largest tenant, The Boeing Company, leased an aggregate of approximately 831,300 rentable square feet of office space under seven separate leases, representing approximately 5.8% of the Company’s total annual base rental revenues. In April 2005, The Boeing Company extended, renewed or otherwise modified three of its existing leases. It extended one lease, which was scheduled to expire in January 2006, at a building located in El Segundo, encompassing approximately 101,000 rentable square feet. The extended lease expires in January 2007 and can be terminated by either party with 60-days advanced notice no earlier than April 30, 2006. The Boeing Company also renewed one lease at a building located in Anaheim, encompassing approximately 65,500 rentable square feet. The lease, which was originally scheduled to expire in October 2005, was extended through October 2010. In addition, an agreement was signed for a lease in Long Beach that was scheduled to expire in September 2005, whereby The Boeing Company will continue to pay rent on its lease, which encompasses approximately 43,600 rentable square feet, through May 31, 2005. Effective June 1, 2005 another company will take possession and begin paying rent on approximately 28,100 rentable square feet that is currently leased to The Boeing Company. For the period June 1, 2005 through September 30, 2005 The Boeing Company will continue to occupy and pay rent on the remaining approximately 15,500 rentable square feet. Furthermore, one lease, encompassing approximately 211,100 rentable square feet, is scheduled to expire in December 2007; however, under the terms of the lease, The Boeing Company has the right to terminate this lease on December 31, 2006 by giving the Company written notice one year in advance. The other three leases are scheduled to expire at various dates between August 2005 and March 2009.

Intuit Inc.    As of March 31, 2005, Intuit, Inc. (“Intuit”), the Company’s sixth largest tenant, leased an aggregate of approximately 264,000 rentable square feet of office space under three separate leases, representing approximately 2.2% of the Company’s total annual base rental revenues. In March 2005, the Company executed a 10-year lease agreement with Intuit for approximately 365,000 rentable square feet. Under this agreement, Intuit will lease three of the four buildings in an office complex that the Company has committed to develop in

22

the I-56 Corridor submarket in San Diego County. See additional information regarding the Company’s development projects under the caption “—Development and redevelopment programs.” The agreement also provides Intuit with the option to lease the fourth building. One of the earlier leases, encompassing approximately 212,000 rentable square feet, is scheduled to expire in April 2007. In connection with the new lease agreement, Intuit has the option to remain in approximately 141,000 rentable square feet of this space until it can occupy the new buildings, which is expected to be in the third quarter of 2007. In addition, Intuit has the option to extend this lease for the remaining 71,000 rentable square feet for up to two years. This second option must be exercised by January 1, 2006. The other two leases, which are in the Long Beach and Calabasas submarkets and encompass approximately 49,000 and 3,000 rentable square feet, are scheduled to expire in July 2014 and December 2005, respectively. Upon commencement of the new San Diego lease, Intuit is projected to become the Company’s largest tenant based on its percentage of the Company’s total annual base rent.

Development and redevelopment programs.    Management believes that a significant portion of the Company’s potential growth over the next several years will continue to come from its development pipeline. During 2002 and 2003, the Company scaled back its development activity as result of the economic environment and its impact on the Company’s ability to lease projects within budgeted timeframes. However, as San Diego County remains one of the strongest market in Southern California, the Company has continued to aggressively seek development opportunities in the region. In March 2005, the Company committed to develop a four-building office complex in the I-56 Corridor submarket. The Company has pre-leased three of the four buildings, or 78% of the rentable square feet, to a single tenant and expects to complete the project by the third quarter of 2007. The project has a total estimated investment of $145 million and will encompass an aggregate of approximately 466,000 rentable square feet. See additional information under the caption “—Recent Information Regarding Significant Tenants—Intuit, Inc.” In addition, the Company commenced construction in July 2004 on the third phase of its Innovation Corporate Center, which is located in the San Diego County I-15 Corridor submarket. The first two phases of this development project, which encompass an aggregate of approximately 289,000 rentable square feet, are 100% leased. The third phase will include two office buildings and will encompass an aggregate of approximately 103,000 rentable square feet and has a total estimated investment of approximately $23 million. The Company does not currently have any lease commitments for these buildings as of March 31, 2005. However, management believes the prospects of leasing the project are positive given that the number of businesses actively seeking new office space in the region continues to grow.

The Company also owns approximately 41.6 acres of undeveloped land upon which the Company currently expects to develop an aggregate of approximately 0.8 million rentable square feet of office space within the next three to five years. All of the Company’s undeveloped land is located in San Diego County. See additional information regarding the Company’s development portfolio under the caption “Development and Redevelopment” in this report.

Management believes that another source of the Company’s potential growth over the next several years will come from redevelopment opportunities within its existing portfolio. Redevelopment efforts can achieve similar returns to new development with reduced entitlement risk and shorter construction periods. The Company’s redevelopment portfolio currently consists of an office building in El Segundo for which the Company performed extensive interior refurbishments. The building had previously been occupied by a single tenant for approximately 30 years. This project, which encompasses approximately 241,600 rentable square feet, was completed in 2004 and is expected to be added to the stabilized portfolio in the third quarter of 2005. As of March 31, 2005, this property was 19% leased. See additional information regarding the Company’s in-process redevelopment portfolio under the caption “Development and Redevelopment” in this report. Depending on market conditions, the Company will continue to pursue future redevelopment opportunities in its strategic submarkets where no land available for development exists.

The Company has a proactive planning process by which it continually evaluates the size, timing and scope of its development and redevelopment programs and, as necessary, scales activity to reflect the economic conditions and the real estate fundamentals that exist in the Company’s strategic submarkets. However, the

23

Company may be unable to lease committed development or redevelopment properties at expected rental rates or within projected timeframes or complete projects on schedule or within budgeted amounts, which could adversely affect the Company’s financial condition, results of operations and cash flows.

Other Factors.    The Company’s operating results are and may continue to be affected by uncertainties and problems associated with the deregulation of the utility industry in California since 95.6% of the total rentable square footage of the Company’s stabilized portfolio is located in California. Energy deregulation has resulted in higher utility costs in some areas of the state and intermittent service interruptions. In addition, primarily as a result of the events of September 11, 2001, the Company’s annual insurance costs increased across its portfolio by approximately 14% during 2002, approximately 11% during 2003, approximately 12% during 2004, and approximately 3% year to date in 2005. As of the date of this report, the Company had not experienced any material effects arising from either of these issues.

In addition, the California State legislature is currently evaluating split tax roll legislation, which if enacted, could have a material effect on the Company’s operating results. If the current initiative is passed, the tax rate on commercial property in California would increase, which would result in significant increases in real estate taxes for the Company’s properties located in California.

Incentive Compensation.    The Company has long-term incentive compensation programs that provide for cash and stock compensation to be earned by the Company’s senior officers if the Company attains certain performance measures that are based on annualized shareholder returns on an absolute and a relative basis as well as certain other financial, operating and development targets. As a result, accrued incentive compensation in future periods is affected by the ten-day average closing price per share of the Company’s common stock at the end of each quarter. Future increases or decreases in the price per share of the Company’s common stock and the resultant cumulative annualized shareholder return calculations will cause an increase or decrease to general and administrative expenses and a corresponding decrease or increase to net income available to common shareholders. Under the absolute component of a special long-term plan for the Company’s executive officers, every $1 change in the Company’s ten-day average closing stock price equates to an approximate $1.7 million change in the total amount payable at the end of the three-year term of the plan (see Note 7 to the Company’s consolidated financial statements for further discussion about the program). Management cannot predict the amounts that will be ultimately recorded in future periods related to these programs since they are significantly influenced by the Company’s stock price and market conditions.

Results of Operations

As of March 31, 2005, the Company’s stabilized portfolio was comprised of 82 office properties (the “Office Properties”) encompassing an aggregate of approximately 7.6 million rentable square feet, and 48 industrial properties (the “Industrial Properties,” and together with the Office Properties, the “Properties”), encompassing an aggregate of approximately 4.5 million rentable square feet. The Company’s stabilized portfolio of operating properties consists of all the Properties, and excludes properties recently developed or redeveloped by the Company that have not yet reached 95.0% occupancy and are within one year following substantial completion (“lease-up” properties) and projects currently under construction.

As of March 31, 2005, the Office and Industrial Properties represented 84.7% and 15.3%, respectively, of the Company’s annualized base rent. For the three months ended March 31, 2005, average occupancy in the Company’s stabilized portfolio was 94.3% compared to 90.8% for the three months ended March 31, 2004. As of March 31, 2005, the Company had approximately 705,500 rentable square feet of vacant space in its stabilized portfolio compared to 1,103,400 rentable square feet as of March 31, 2004.

The following table reconciles the changes in the rentable square feet in the Company’s stabilized portfolio of operating properties from March 31, 2004 to March 31, 2005. Rentable square footage in the Company’s portfolio of stabilized properties remained consistent at approximately 12.0 million rentable square feet at March 31, 2005, compared to March 31, 2004.

Comparison of the Three Months Ended March 31, 2005 to the Three Months Ended March 31, 2004

Management internally evaluates the operating performance and financial results of its portfolio based on Net Operating Income for the following segments of commercial real estate property: Office Properties and Industrial Properties. The Company defines Net Operating Income as operating revenues from continuing operations (rental income, tenant reimbursements and other property income) less property and related expenses from continuing operations (property expenses, real estate taxes, provision for bad debts and ground leases). The Net Operating Income segment information presented within this Management’s Discussion and Analysis consists of the same Net Operating Income segment information disclosed in Note 9 of the Company’s consolidated financial statements in accordance with Statement of Financial Accounting Standards No. 131 “Disclosures about Segments of an Enterprise and Related Information.” The following table reconciles the Company’s Net Operating Income by segment to the Company’s net income for the three months ended March 31, 2005 and 2004.

(1) Office properties owned and stabilized at January 1, 2004 and still owned and stabilized at June 30, 2005.

Total revenues from Office Properties increased $6.1 million, or 13.8%, to $50.2 million for the three months ended March 31, 2005 compared to $44.1 million for the three months ended March 31, 2004. Rental income from Office Properties increased $6.2 million, or 15.8%, to $45.3 million for the three months ended March 31, 2005 compared to $39.1 million for the three months ended March 31, 2004. Rental income generated by the Core Office Portfolio increased $2.6 million, or 7.2%, for the three months ended March 31, 2005 as compared to the three months ended March 31, 2004. The increase in the Core Office Portfolio is primarily due to an increase in occupancy. Average occupancy in the Core Office Portfolio increased 5.6% to 94.6% for the three months ended March 31, 2005 compared to 89.0% for the same period in 2004. The remaining $3.6 million increase in rental income was attributable to a $2.3 million increase in rental income generated by the two office buildings acquired by the Company in the fourth quarter of 2004 (the “Office Acquisition Properties”), a $0.9 million increase in rental income generated by the office redevelopment properties that were completed during 2004 (the “Office Redevelopment Properties”) and a $0.4 million increase in rental income generated by the office development property that was added to the stabilized portfolio in the third quarter of 2004 (the “Office Development Property”).

Tenant reimbursements from Office Properties increased $0.3 million, or 6.5%, to $4.7 million for the three months ended March 31, 2005 compared to $4.4 million for the three months ended March 31, 2004. Tenant reimbursements generated by the Core Office Portfolio remained consistent at $4.4 million for the three months ended March 31, 2005 compared to the same period in 2004. An increase of $0.2 million in tenant reimbursements is attributable to the Office Redevelopment Properties and an increase of $0.1 million in tenant reimbursements is attributable to the Office Development Property. Other property income from Office Properties decreased approximately $0.4 million, or 72.3%, to $0.1 million for the three months ended March 31, 2005 compared to $0.5 million for the three months ended March 31, 2004. Other property income for both

27

periods consisted primarily of lease termination fees and other related income associated with early lease terminations within the Core Office Portfolio.

Total expenses from Office Properties increased $2.4 million, or 20.4%, to $14.0 million for the three months ended March 31, 2005 compared to $11.6 million for the three months ended March 31, 2004. Property expenses from Office Properties increased $0.9 million, or 12.0%, to $8.8 million for the three months ended March 31, 2005 compared to $7.9 million for the three months ended March 31, 2004. An increase of $0.5 million, or 6.5%, was generated by the Core Office Portfolio. This increase was primarily attributable to an increase in property management expenses, janitorial and other contract services related to the increase in occupancy. Of the remaining increase of $0.4 million in property expenses, $0.3 million was attributable to the Office Acquisition Properties and $0.1 million was attributable to both the Office Development Property and the Office Redevelopment Properties. Real estate taxes from Office Properties increased $0.5 million, or 16.5%, for the three months ended March 31, 2005 as compared to the same period in 2004. Real estate taxes for the Core Office Portfolio increased $0.2 million, or 5.9%, for the three months ended March 31, 2005 compared to the three months ended March 31, 2004. The remaining $0.3 million increase in real estate taxes was due to a $0.2 million increase in property taxes generated by the Office Acquisition Properties and a $0.1 million increase in property taxes generated by the Office Redevelopment Properties. The provision for bad debts from Office Properties increased $0.8 million, or 340.2%, for the three months ended March 31, 2005 compared to the three months ended March 31, 2004. During the three months ended March 31, 2005, the Company increased its reserves for certain tenants on the Company’s watchlist that the Company closely monitors because the tenant may be experiencing financial difficulties or they are consistently late in paying outstanding balances. The Company evaluates its reserve levels on a quarterly basis. Ground lease expense for Office Properties increased $0.1 million, or 22.7%, to $0.4 million for the three months ended March 31, 2005 compared to $0.3 million for the three months ended March 31, 2004.

Net Operating Income, as defined, from Office Properties increased $3.7 million, or 11.4%, to $36.2 million for the three months ended March 31, 2005 compared to $32.5 million for the three months ended March 31, 2004. Of this increase, $0.8 million was generated by the Core Office Portfolio due to an increase in occupancy in this portfolio as mentioned above. Of the remaining increase of $2.9 million, $1.6 million was generated by the Office Acquisition Properties, $0.9 million was generated by the Office Redevelopment Properties and $0.4 million was generated by the Office Development Property.

(1) The Total Industrial Portfolio is the same as the Company’s Core Industrial Portfolio at March 31, 2005, which represents properties owned and stabilized at January 1, 2004 and still owned and stabilized at June 30, 2005, excluding the property classified as held for sale as of June 30, 2005.

28

Total revenues from Industrial Properties increased $0.4 million to $9.1 million for the three months ended March 31, 2005 as compared to $8.7 million for the three months ended March 31, 2004. Rental income from Industrial Properties increased $0.2 million, or 2.2%, to $8.0 million for the three months ended March 31, 2005 compared to $7.8 million for the three months ended March 31, 2004. This increase was primarily due to an increase in occupancy. Average occupancy in the Industrial Properties increased 1.0% to 94.7% for the three months ended March 31, 2005 as compared to 93.7% for the three months ended March 31, 2004.

Tenant reimbursements from Industrial Properties increased $0.1 million, or 15.6%, to $1.0 million for the three months ended March 31, 2005 compared to $0.9 million for the three months ended March 31, 2004. This increase is primarily due to an increase in occupancy in this portfolio. Other property income from Industrial Properties increased $0.1 million for the three months ended March 31, 2005 compared to the three months ended March 31, 2004. Other Property Income for both periods consisted primarily of lease termination fees.

Total expenses from Industrial Properties increased $0.1 million, or 9.5%, to $1.3 million for the three months ended March 31, 2005 compared to $1.2 million for the three months ended March 31, 2004. Property expenses from Industrial Properties remained consistent at approximately $0.6 million during the three months ended March 31, 2005 compared to the same period in 2004. Real estate taxes from Industrial Properties remained consistent at approximately $0.7 million during the three months ended March 31, 2005 compared to the same period in 2004. The provision for bad debts increased by $0.1 million for the three months ended March 31, 2005 as compared to the three months ended March 31, 2004. The Company evaluates its reserve levels on a quarterly basis.

Net Operating Income, as defined, from Industrial Properties increased $0.2 million, or 3.5% to $7.7 million for the three months ended March 31, 2005 compared to $7.5 million for the three months ended March 31, 2004.

Non-Property Related Income and Expenses

Interest and other income decreased approximately $0.2 million, or 81.4%, to $0.1 million for the three months ended March 31, 2005 compared to $0.3 million for the three months ended March 31, 2004. The decrease is primarily due to a $0.1 million net realized gain from the sale of stock that the Company received in March 2004 in satisfaction of a creditor’s claim under a lease that was terminated early. In addition, during the three months ended March 31, 2004, the Company recorded $0.1 million in non-recurring interest earned in connection with a reimbursement of prior year supplemental property taxes.

General and administrative expenses decreased $1.7 million, or 21.7%, to $6.0 million for the three months ended March 31, 2005 compared to $7.7 million for the three months ended March 31, 2004. The decrease was primarily due to a $1.9 million decrease in the charge for accrued incentive compensation and was driven by a special long-term incentive plan for the Company’s executive officers for which the amount payable under the plan is based on the Company’s absolute and relative shareholder returns (see Note 7 to the Company’s consolidated financial statements for further discussion about the program). Compensation expense under this program is accounted for using variable plan accounting. The Company estimates the amount to be paid based on the average closing share price of the Company’s common stock as reported on the NYSE for the last ten days of the period, and records compensation expense equal to that portion of the total compensation applicable to the portion of the performance period that has elapsed through the end of the period. The decrease in the charge for accrued incentive compensation is due to the decline in the share price of the Company’s stock at the end of the first quarter of 2005 as compared to December 31, 2004 and the resultant cumulative adjustment recorded as of March 31, 2005 for the change in estimated compensation expense attributable to prior periods. The amounts recorded in future periods related to this plan will increase and decrease as the ten-day average price per share of the Company’s common stock at the end of each period increases or decreases.

Net interest expense increased $0.4 million, or 4.5%, to $9.6 million for the three months ended March 31, 2005 compared to $9.2 million for the three months ended March 31, 2004. Gross interest and loan fee expense,

29

before the effect of capitalized interest and loan fees, increased $0.4 million, or 3.8%, to $11.7 million for the three months ended March 31, 2005 compared to $11.3 million for the three months ended March 31, 2004. Total capitalized interest and loan fees were $2.1 million for both the three months ended March 31, 2005 and the three months ended March 31, 2004.

Depreciation and amortization increased $2.5 million, or 18.6%, to $16.2 million for the three months ended March 31, 2005 compared to $13.7 million for the three months ended March 31, 2004. An increase of $1.0 million and $0.1 million was generated by the Core Office Portfolio and the Core Industrial Portfolio, respectively. These increases were mainly attributable to expenditures incurred subsequent to March 31, 2004 for capital and tenant improvements. Of the remaining $1.4 million increase in depreciation and amortization, $1.1 million was generated by the Office Acquisition Properties, $0.2 million was generated by the Office Redevelopment Properties and $0.1 million was generated by the Office Development Property.

Liquidity and Capital Resources

Current Sources of Capital and Liquidity

The Company seeks to create and maintain a capital structure that allows for financial flexibility and diversification of capital resources. The Company’s primary source of liquidity to fund distributions, debt service, leasing costs and capital expenditures is net cash from operations. The Company’s primary sources of liquidity to fund development and redevelopment costs, potential undeveloped land and property acquisitions, temporary working capital and unanticipated cash needs are the Company’s $425 million unsecured revolving line of credit, proceeds received from the Company’s disposition program and construction loans. As of March 31, 2005, the Company’s total debt as a percentage of total market capitalization (presented under—Factors That May Influence Future Sources of Capital and Liquidity) was 33.8%. As of March 31, 2005, the Company’s total debt plus preferred equity as a percentage of total market capitalization was 42.4%.

As of March 31, 2005, the Company had borrowings of $153.0 million outstanding under its revolving unsecured line of credit (the “Credit Facility”) and availability of approximately $272.0 million. The Credit Facility bears interest at an annual rate between LIBOR plus 1.00% and LIBOR plus 1.70% depending upon the Company’s leverage ratio at the time of borrowing (4.01% at March 31, 2005), and matures in October 2007 with an option to extend the maturity for one year. The fee for unused funds ranges from an annual rate of 0.20% to 0.30% depending on the Company’s leverage ratio. The Company expects to use the Credit Facility to finance development and redevelopment expenditures, to fund potential acquisitions and for other general corporate uses.

Factors That May Influence Future Sources of Capital and Liquidity

The Credit Facility, unsecured senior notes, and certain other secured debt agreements contain covenants and restrictions requiring the Company to meet certain financial ratios and reporting requirements. Some of the more restrictive covenants include a maximum total debt to total assets ratio, a maximum total secured debt to total assets ratio, minimum debt service coverage and fixed charge coverage ratios, a minimum consolidated tangible net worth and a limit of development activities as compared to total assets. Non-compliance with one or more of the covenants and restrictions could result in the full or partial principal balance of the associated debt becoming immediately due and payable. The Company was in compliance with all its covenants at March 31, 2005.

33

The following table sets forth certain information with respect to the Company’s aggregate debt composition at March 31, 2005 and December 31, 2004:

	Percentage of Total Debt				Weighted-Average Interest Rate
	March 31, 2005		December 31, 2004		March 31, 2005		December 31, 2004

(1) At March 31, 2005 and December 31, 2004, the Company had an interest-rate swap agreement, which expires in November 2005, to fix LIBOR on $50 million of its variable-rate debt at 2.57%.

(2) At March 31, 2005 and December 31, 2004, the Company had two interest-rate swap agreements, which expire in December 2006, to fix LIBOR on $50 million of its variable-rate debt at 2.98%.

(3) At December 31, 2004, the Company had an interest-rate swap agreement to fix LIBOR on $50 million of its variable-rate debt at 4.46%. The swap expired in January 2005.

Contractual Obligations

The following table provides information with respect to the maturities and scheduled principal repayments of the Company’s secured debt and Credit Facility and scheduled interest payments of the Company’s fixed-rate debt and interest-rate swap agreements at March 31, 2005 and provides information about the minimum commitments due in connection with the Company’s ground lease obligations and capital commitments at March 31, 2005. The table does not reflect available maturity extension options.

(1) The Credit Facility has a one-year extension option.

(2) As of March 31, 2005, 85.6% of the Company’s debt was contractually fixed or constructively fixed through interest-rate swap agreements. The information in the table above reflects the Company’s projected interest rate obligations for these fixed-rate payments based on the contractual interest rates, interest payment dates and scheduled maturity dates. The remaining 14.4% of the Company’s debt bears interest at variable rates and the variable interest rate payments are based on LIBOR plus a spread that ranges from 1.00% to 1.70%. The interest payments on the Company’s variable-rate debt have not been reported in the table above because management cannot reasonably determine the future interest obligations on its variable-rate debt as management cannot predict what LIBOR rates will be in the future. As of March 31, 2005, one-month LIBOR was 2.87%. See additional information regarding the Company’s debt and derivative instruments under Item 3: Quantitative and Qualitative Disclosures about Market Risk.

(3) Represents the scheduled interest payments for the Company’s total outstanding interest-rate swap agreements as of March 31, 2005, based on the contractual interest rates, interest payment dates and maturity dates. The interest payments are reported at the gross amount and do not reflect the variable payment to be received from the counterparty and the offsetting variable interest to be paid on the associated debt. The Company employs derivative instruments for hedging purposes only and does not hold interest-rate swaps for speculative purposes. These cash flow hedges effectively convert a portion of the Company’s variable-rate debt to fixed-rate debt. The Company had interest-rate swap agreements with a total notional amount of $100 million as of March 31, 2005.

(4) The Company has noncancelable ground lease obligations for the SeaTac Office Center in Seattle, Washington expiring in December 2032, with an option to extend the lease for an additional 30 years; and Kilroy Airport Center in Long Beach, California with a lease period for Phases I, II, III and IV expiring in July 2084.

(5) Amounts represent commitments under signed leases and contracts. See further discussion under the caption “Capital Commitments” below.

Capital Commitments

As of March 31, 2005, the Company had two development projects under construction with a total estimated investment of $23 million. The Company also had one redevelopment project that was in the lease-up phase with a total estimated investment of $69 million. In addition, in March 2005, the Company committed to develop a four-building office complex, which is 78% pre-leased to a single tenant. The Company expects to begin construction in the third quarter of 2005, and the project has a total estimated investment of approximately $145 million. The Company has incurred aggregate costs of approximately $89 million on all of these projects as of March 31, 2005, and currently projects it could spend approximately $40 million of the remaining $148 million of presently budgeted development costs during the remainder of 2005, depending on leasing activity. In addition, the Company had a development project and a redevelopment project that were added to the Company’s stabilized portfolio in 2003 and 2005, respectively, which had not yet reached stabilized occupancy as of March 31, 2005. Depending on leasing activity, the Company currently projects it could spend

35

approximately $10 million for these projects during the remainder of 2005. See additional information regarding the Company’s in-process development and redevelopment portfolio under the caption “Development and Redevelopment.”

As of March 31, 2005, the Company had executed leases that committed the Company to $18 million in unpaid leasing costs and tenant improvements and the Company had contracts outstanding for approximately $1 million in capital improvements at March 31, 2005. In addition, during the remainder of 2005, the Company plans to spend approximately $9 million to $13 million in capital improvements, tenant improvements, and leasing costs for properties within the Company’s stabilized portfolio, depending on leasing activity. Capital expenditures may fluctuate in any given period subject to the nature, extent and timing of improvements required to maintain the Company’s properties. Tenant improvements and leasing costs may also fluctuate in any given period depending upon factors such as the type of property, the term of the lease, the type of lease, the involvement of external leasing agents and overall market conditions.

Other Liquidity Needs

The Company is required to distribute 90% of its REIT taxable income (excluding capital gains) on an annual basis in order to qualify as a REIT for federal income tax purposes. Accordingly, the Company intends to continue to make, but has not contractually bound itself to make, regular quarterly distributions to common stockholders and common unitholders from cash flow from operating activities. All distributions are at the discretion of the Board of Directors. The Company may be required to use borrowings under the Credit Facility, if necessary, to meet REIT distribution requirements and maintain its REIT status. The Company has historically distributed amounts in excess of its taxable income resulting in a return of capital to its stockholders, and currently has the ability to not increase its distributions to meet its REIT requirements for 2005. The Company considers market factors and Company performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to shareholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which are consistent with the Company’s intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit and interest-bearing bank deposits. On March 9, 2005, the Company declared a regular quarterly cash dividend of $0.51 per common share, which was paid on April 15, 2005 to stockholders of record on March 31, 2005. This dividend is equivalent to an annual rate of $2.04 per share. In addition the Company is required to make quarterly distributions to its Series A Preferred unitholders and Series E and Series F Preferred Stockholders, which in aggregate total approximately $15 million of annualized preferred dividends and distributions.

The Company’s Board of Directors has approved a share repurchase program, pursuant to which the Company is authorized to repurchase up to an aggregate of four million shares of its outstanding common stock. An aggregate of 1,227,500 shares currently remain eligible for repurchase under this program. The Company may opt to repurchase shares of its common stock in the future depending upon market conditions. The Company did not repurchase shares of common stock under this program during the three months ended March 31, 2005.

The Company believes that it will have sufficient capital resources to satisfy its liquidity needs over the next twelve-month period. The Company expects to meet its short-term liquidity needs, which may include principal repayments of its debt obligations, capital expenditures and distributions to common and preferred stockholders and unitholders, through retained cash flow from operations and borrowings under the Credit Facility.

The Company expects to meet its long-term liquidity requirements, which may include property and undeveloped land acquisitions and additional future development and redevelopment activity, through retained cash flow, borrowings under the Credit Facility, additional long-term secured and unsecured borrowings, dispositions of non-strategic assets, issuance of common or preferred units of the Operating Partnership, and the potential issuance of debt or equity securities of the Company. The Company does not intend to reserve funds to retire existing debt upon maturity. The Company presently expects to refinance such debt at maturity or retire such debt through the issuance of equity securities, as market conditions permit.

36

Off Balance Sheet Arrangements

As of March 31, 2005, the Company did not have any off-balance sheet transactions, arrangements or obligations, including contingent liabilities.

Historical Cash Flows

The principal sources of funding for development, redevelopment, acquisitions and capital expenditures are cash flow from operating activities, the Credit Facility, secured and unsecured debt financing and proceeds from the Company’s dispositions. The Company’s net cash provided by operating activities decreased $1.0 million, or 3.9%, to $23.2 million for the three months ended March 31, 2005 compared to the $24.2 million for the three months ended March 31, 2004. The decrease is primarily attributable to a decrease in lease termination fee payments received by the Company during the three months ended March 31, 2005 as compared to the three months ended March 31, 2004. This decrease was partially offset by an increase in average occupancy in the Core Office Portfolio. For the three months ended March 31, 2005, average occupancy in this portfolio was 94.6% as compared to 89.0% for the three months ended March 31, 2004.

Net cash provided by investing activities increased $35.3 million, or 260.1%, to $21.7 million net cash provided by investing activities for the three months ended March 31, 2005 compared to $13.6 million net cash used in investing activities for the three months ended March 31, 2004. The increase was primarily attributable to the disposition of four buildings in March 2005 (see Note 2 to the Company’s consolidated financial statements for further discussion of the dispositions).

Net cash used in financing activities increased $25.0 million, or 181.3%, to $38.8 million for the three months ended March 31, 2005 compared to $13.8 million for the three months ended March 31, 2004. This increase was primarily attributable to a $23.9 million increase in net repayments on the Company’s debt for the three months ended March 31, 2005 compared to the three months ended March 31, 2004, resulting from the repayment of borrowings under the Credit Facility with the net proceeds from the March 2005 dispositions.

Non-GAAP Supplemental Financial Measure: Funds From Operations

Management believes that Funds From Operations (“FFO”) is a useful supplemental measure of the Company’s operating performance. The Company computes FFO in accordance with the White Paper on FFO approved by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). The White Paper defines FFO as net income or loss computed in accordance with generally accepted accounting principles (“GAAP”), excluding extraordinary items, as defined by GAAP, and gains and losses from sales of depreciable operating property, plus real estate related depreciation and amortization (excluding amortization of deferred financing costs and depreciation of non-real estate assets), and after adjustment for unconsolidated partnerships and joint ventures. Other REITs may use different methodologies for calculating FFO, and accordingly, the Company’s FFO may not be comparable to other REITs.

Because FFO excludes depreciation and amortization, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses and interest costs, providing perspective on operating performance not immediately apparent from net income. In addition, management believes that FFO provides useful information to the investment community about the Company’s operating performance when compared to other REITs since FFO is generally recognized as the industry standard for reporting the operations of REITs.

However, FFO should not be viewed as an alternative measure of the Company’s operating performance since it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially impact the Company’s results from operations.

37

The following table reconciles the Company’s FFO to the Company’s GAAP net income available for common stockholders for the three months ended March 31, 2005 and 2004.

	Three Months Ended March 31,
	2005			2004
Net income available for common stockholders	$	12,743		$	5,984
Adjustments:
Minority interest in earnings of Operating Partnership		1,718			986
Depreciation and amortization		16,322			13,986
Net gain on dispositions of operating properties		(5,779	)
Funds From Operations(1)	$	25,004		$	20,956

(1) Reported amounts are attributable to common stockholders and common unitholders.

Inflation

The majority of the Company’s tenant leases require tenants to pay most operating expenses, including real estate taxes, utilities, insurance and increases in common area maintenance expenses, which reduces the Company’s exposure to increases in costs and operating expenses resulting from inflation.

ITEM 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports under the Securities Exchange Act of 1934 is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any system of controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Subsequent to the filing of the original Form 10-Q for the quarter ended March 31, 2005, management discovered an error in the computation of income from continuing operations per common share included within the consolidated statements of operations, and determined that the error required the restatement of per share amounts for income from continuing operations, basic and diluted, for the quarters ended March 31, 2005 and 2004. The Company incorrectly calculated the per share results of income from continuing operations, basic and diluted, by not deducting the impact of dividends paid and accrued to its preferred stockholders. In accordance with Statement of Financial Accounting Standards No. 128, “Earnings per Share,” the Company should have presented income from continuing operations per share net of preferred dividends paid and accrued to its preferred stockholders. Also subsequent to filing of the original Form 10-Q for the quarter ended March 31, 2005, the Company’s management concluded that it had been incorrectly classifying two items on the consolidated statements of cash flows. First, distributions to cumulative redeemable preferred unitholders were included in the Company’s consolidated statements of cash flows as an operating activity when, in accordance with Statement of Financial Accounting Standards No. 95 “Statement of Cash Flows”, distributions paid to cumulative redeemable preferred unitholders should have been classified as a financing activity. Second, capital expenditures for operating properties, development and redevelopment projects and undeveloped land were reflected on an accrual basis of accounting rather than the cash paid for such expenditures in investing activities in the consolidated statements of cash flows. The adjustment to reflect these expenditures on a cash basis in investing activities for each period is offset by an adjustment for the same amount in cash flows from operating activities to appropriately reflect the associated increases and decreases in accounts payable, accrued expenses and other liabilities.

38

The required restatements caused management to conclude that the Company had a material weakness in its internal control over financial reporting because the controls over the initial analysis of accounting guidance did not identify the impact of significant new corporate transactions on a per share disclosure required on the consolidated statements of operations or the appropriate classification of two specific items on the consolidated statements of cash flows.

As required by SEC Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures as of the end of the period covered by this report, which included consideration of the restatements. Based on the foregoing, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were not effective as of the end of the period covered by this report.

In light of this conclusion, the Company performed additional technical review and analysis to ensure its consolidated financial statements are prepared in accordance with generally accepted accounting principles. Accordingly, management believes that the financial statements included in this report fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented.

Changes in Internal Control Over Financial Reporting

Management had previously concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2005 and reported that there was no change in the Company’s internal control over financial reporting that occurred during the three months ended March 31, 2005 that materially affected, or was reasonably likely to materially affect, the internal control over financial reporting. However, in connection with the restatements of the Company’s consolidated financial statements for the quarter ended March 31, 2005, as fully described in Note 14 of this Quarterly Report on Form 10-Q/A for the quarter ended March 31, 2005, management determined that the material weakness described above existed as of March 31, 2005 and has, as a result, effected changes to the Company’s internal control over financial reporting subsequent to the period covered by this report, that have materially affected the Company’s internal control over financial reporting. The Company has implemented procedures to more formally document and review the technical analysis of all relevant accounting literature that is performed to evaluate the accounting treatment and presentation and disclosure requirements for significant and/or non-routine transactions. This review will be performed both when a transaction is completed for the first time and when a similar repeat transaction is completed, if it is significant. Management believes these enhanced procedures provide additional internal control over financial reporting and improve the ability of management to identify any potential accounting implications prior to and during the comprehensive review of the Company’s consolidated financial statements. In addition, the Company has implemented a more comprehensive review of the consolidated statements of cash flows. Management believes these changes remediated the material weakness discussed above.
