1. Organization and Description of Business

The
terms Thomas Properties, the Company, us, we and our as used in this report refer to Thomas Properties Group, Inc. together with our Operating Partnership, Thomas Properties Group, L.P.
(the Operating Partnership).

We were formed to succeed to certain businesses of the Thomas Properties predecessor (Thomas
Properties Group, Inc. Predecessor, or TPGI Predecessor), which was not a legal entity but rather a combination of real estate entities and operations. We own, manage, lease, acquire and develop real estate, consisting primarily of
office properties and related parking garages, located in Southern California; Sacramento, California; Philadelphia, Pennsylvania; Northern Virginia; Houston, Texas; and Austin, Texas. The owners of TPGI Predecessor were Mr. James A.
Thomas, our Chairman, Chief Executive Officer and President, and certain others who had minor ownership interests.

We were incorporated in
the State of Delaware on March 9, 2004. On October 13, 2004, we completed our initial public offering (the Offering). Concurrent with the consummation of the Offering, Thomas Properties and the Operating Partnership, together
with the partners and members of the affiliated partnerships and limited liability companies of TPGI Predecessor and other parties which held direct or indirect ownership interests in the properties engaged in certain formation transactions. The
formation transactions were designed to (i) continue the operations of TPGI Predecessor, (ii) enable us to raise the necessary capital to acquire increased interests in certain of the properties and repay certain property level
indebtedness, (iii) fund joint venture capital commitments, (iv) provide capital for future acquisitions, and (v) fund future development costs at our development properties.

Our operations are carried on through our Operating Partnership. We are the sole general partner in the Operating Partnership. Pursuant to contribution
agreements among the owners of TPGI Predecessor and the Operating Partnership, the Operating Partnership received a contribution of interests in the real estate properties, as well as the investment advisory, property management, leasing and real
estate development operations of TPGI Predecessor in exchange for limited partnership units (Units) in the Operating Partnership issued to the contributors and the assumption of debt and other specified liabilities. As of March 31,
2009, we held a 65.0% interest in the Operating Partnership which we consolidate, as we have control over the major decisions of the Operating Partnership.

As of March 31, 2009, we were invested in the following real estate properties:

Accounting Pronouncements Adopted January 1, 2009

Accounting for Noncontrolling Interests

In December
2007, FASB issued FASB Statement No. 160, Noncontrolling Interests in Consolidated Financial Statementsan Amendment of Accounting Research Bulletin No. 51 (SFAS 160). SFAS 160 requires all entities to report
noncontrolling interests in subsidiaries within equity in the consolidated financial statements, but separate from the parent shareholders equity. SFAS No. 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
was effective January 1, 2009 for us. The retrospective presentation and disclosure requirements outlined by SFAS 160 have been incorporated into this Quarterly Report on Form 10-Q for the interim period ended March 31, 2009. The adoption
of SFAS 160 resulted in a reclassification of minority interests to a separate component of total equity on the balance sheet and net income attributable to noncontrolling interests is shown as a reduction from net income in calculating net income
available to common stockholders on the statement of operations. All previous references to minority interests in the consolidated financial statements have been revised to noncontrolling interests. In connection with the
issuance of SFAS 160, certain revisions were also made to EITF Topic D-98 Classification and Measurement of Redeemable Securities (EITF D-98). See Notes 6 and 7 for additional details.



2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying
consolidated financial statements of our company include all the accounts of Thomas Properties Group, Inc., the Operating Partnership and the subsidiaries of the Operating Partnership. Property interests contributed to the Operating Partnership by
Mr. Thomas and entities majority owned by him in exchange for Units have been accounted for as a reorganization of entities under common control in a manner similar to a pooling of interests. Accordingly, the contributed assets and assumed
liabilities were recorded at TPGI Predecessors historical cost basis, except for the noncontrolling owners share. The pooling-of-interests method of accounting also requires the reporting of results of operations, for the period in which
the combination occurred as though the entities had been combined at either the beginning of the period or inception. Prior to the Offering, Thomas Properties Group, Inc. and the Operating Partnership had no operations. The combination did not
require any material adjustments to conform the accounting policies of the separate entities. The remaining interests, which were acquired for cash and Units, were accounted for as a purchase, and the excess of the purchase price over the related
historical cost basis was allocated to the assets acquired and liabilities assumed.

The real estate entities included in the consolidated
financial statements have been consolidated only for the periods that such entities were under control by us or TPGI Predecessor, or were considered a variable interest entity. The equity method of accounting is utilized to account for investments
in real estate entities over which we have significant influence, but not control over major decisions, including the decision to sell or refinance the properties owned by such entities. All significant intercompany balances and transactions have
been eliminated in the consolidated financial statements.

The interests in Two Commerce Square (beginning October 13, 2004 through
August 5, 2008), not owned by us are reflected as noncontrolling interest. On August 6, 2008, we exercised our option to purchase the remaining 11% interest in Two Commerce Square for $2.0 million, resulting in our 100% ownership of Two
Commerce Square. We are in process of allocating the purchase price of the 11% interest acquired in Two Commerce Square to the acquired tangible assets and identified intangible assets and liabilities as of March 31, 2009. We will do so in the
second quarter of 2009.

We have a $20,510,000 preferred equity interest in Murano. Excluding the preferred equity interest, a third party
has a 27.0% ownership interest in Murano.

##### Table of Contents

Earnings (loss) per share

The computation of basic earnings (loss) per share is based on net earnings (loss) and the weighted average number of shares of our common stock outstanding during the period. The computation of diluted earnings
(loss) per share includes the assumed exercise of outstanding stock options and the effect of the vesting of restricted stock that have been granted, all calculated using the treasury stock method.

Development Activities

Project costs associated with
the development and construction of a real estate project are capitalized as construction in progress. In addition, interest, loan fees, real estate taxes, and general and administrative expenses that are directly associated with and incremental to
our development activities and other costs are capitalized during the period in which activities necessary to get the property ready for its intended use are in progress, including the pre-development and lease-up phases. Once the development and
construction of the building shell of a real estate project is completed, the costs capitalized to construction in progress will be transferred to land and improvements and buildings and improvements. Included in land held for development and
construction in progress is capitalized interest of $21.6 million and $22.6 million as of March 31, 2009 and December 31, 2008, respectively.

Revenue Recognition - Condominium Sales

We have one high-rise condominium project for which we use the percentage of
completion accounting method to recognize revenues and costs. Under the provisions of the Financial Accounting Standards Board (FASB) Statement No. 66, Accounting for Sales of Real Estate (SFAS 66), revenues and costs
for projects are recognized using the percentage of completion method of accounting when construction is beyond the preliminary stage, the buyer is committed to the extent of being unable to require a refund except for non-delivery of the unit,
sufficient units in the project have been sold to ensure that the property will not revert to rental property, the sales proceeds are collectible and the aggregate sales proceeds and the costs of the project can be reasonably estimated. Revenues are
recognized on the individual projects aggregate value of units which have closed and units for which the home buyers have signed binding agreements of sale, less an allowance for cancellations, and are based on the percentage of total
estimated construction costs that have been incurred. The total estimated costs of the project are allocated to these units on a relative sales value basis. Total estimated revenues and construction costs are reviewed periodically, and any change is
applied to current and future periods.

Forfeited customer deposits are recognized as revenue in the period in which we determine that the
customer will not complete the purchase of the condominium unit and when we determine that we have the right to keep the deposit. No forfeitures were recognized in the quarters ended March 31, 2009 and 2008.

Gain on Sale of Real Estate

We recognize gains on
sales of real estate when the recognition criteria in SFAS No. 66 Accounting for Sales of Real Estate (SFAS 66) have been met, generally at the time title is transferred and we no longer have substantial continuing
involvement with the real estate asset sold. If the criteria for profit recognition under the full-accrual method are not met, we defer gain recognition and account for the continued operations of the property by applying the deposit or percentage
of completion method, as appropriate, until the appropriate criteria are met. With respect to a parcel we sold at Campus El Segundo in 2006, we deferred a portion of the gain as we were obligated to fund certain infrastructure improvements with
respect to the sold parcel; therefore we recognized the deferred gain on the percentage of completion method. The improvements were completed in 2008 and the remaining deferred gain balance was recognized.

Fair Value Measurements

On January 1, 2008 we
adopted FASB Statement No. 157 Fair Value Measurement (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. SFAS 157
applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances. SFAS 157
emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or
liability. As a basis for considering market participant assumptions in fair value measurements, SFAS 157 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources
independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entitys own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of
the hierarchy). Level 1 inputs utilize quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are
observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted
prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.

Currently, certain of our unconsolidated real estate entities use interest rate caps, floors and collars
to manage the interest rate risk resulting from variable interest payments on floating rate debt. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected
cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities.

To comply with the provisions of FAS 157, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the
respective counterpartys nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we considered the impact of netting and any applicable credit
enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. We have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. We do not have any fair value
measurements using significant unobservable inputs (Level 3) as of March 31, 2009.

The table below presents the assets and
liabilities associated with our unconsolidated investments measured at fair value on a recurring basis as of March 31, 2009, aggregated by the level in the fair value hierarchy within which those measurements fall (in thousands).

Other Recent Accounting Pronouncements

In February 2008, the FASB issued FASB Staff Position No. 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 (SFAS 157-1). SFAS No. 157-1 amends SFAS 157, to exclude FASB Statement
No. 13, Accounting for Leases (SFAS 13), and other accounting pronouncements that address fair value measurements for purposes of lease classification or measurement under SFAS 13. However, this scope exception does not
apply to assets acquired and liabilities assumed in a business combination that are required to be measured at fair value under FASB Statement No. 141 (R), Business Combinations (SFAS 141R), regardless of whether those
assets and liabilities are related to leases. The adoption of FASB Staff Position No. 157-1 did not have a material impact on our financial position or results of operations.

In December 2007, the FASB issued 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 one hundred percent 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 the
beginning of the first annual reporting period beginning after December 15, 2008. The adoption of SFAS 141R did not have a material impact on our financial position or results of operations.

In February 2007, the FASB issued FAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities Including an Amendment of
FASB Statement No. 115. This standard permits entities to choose to measure many financial instruments and certain other items at fair value and is effective for the first fiscal year beginning after November 15, 2007, which for
us means our fiscal year 2008. We did not elect the fair value measurement option for any financial assets or liabilities.

Interim Financial Data

The accompanying interim financial statements are unaudited, but have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and in
conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments
(consisting solely of normal recurring matters) necessary for a fair presentation of the financial statements for these interim periods have been included. The results of operations for the interim periods are not necessarily indicative of the
results to be obtained for the full fiscal year.

Reclassifications

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

##### Table of Contents

TPG/CalSTRS was formed to acquire office properties on a nationwide basis classified as moderate risk
(core plus) and high risk (value add) properties. Core plus properties consist of under-performing properties that we believe can be brought to market potential through improved management. Value-add properties are characterized by unstable net
operating income for an extended period of time, occupancy less than 90% and/or physical or management problems which we believe can be positively impacted by introduction of new capital and/or management. We are required to use diligent efforts to
sell each joint venture property within five years of that property reaching stabilization, except for certain stabilized properties, as to which we are required to perform a hold/sell analysis at least annually and make a recommendation to the
TPG/CalSTRS management committee regarding the appropriate holding period.

The total capital commitment to the joint venture was
$378.3 million as of March 31, 2009, of which approximately $12.4 million and $4.1 million was unfunded by CalSTRS and us, respectively.

A buy-sell
provision may be exercised by either CalSTRS or us. Under this provision, the initiating party sets a price for its interest in the joint venture, and the other party has a specified time to elect to either buy the initiating partys interest
or to sell its own interest to the initiating party. Upon the occurrence of certain events, CalSTRS also has a buy-out option to purchase our interest in the joint venture. The buyout price is based upon a 3% discount to the appraised fair market
value. In addition, the noncontrolling owner of City National Plaza has the option to require the joint venture to purchase its interest for an amount equal to what would be payable to it upon liquidation of the asset at fair market value. The
estimated value of this put option is reflected as redeemable noncontrolling interest in the balance sheets below.

Following
is summarized financial information for the unconsolidated real estate entities as of March 31, 2009 and December 31, 2008 and for the three months ended March 31, 2009 and 2008.

Mr. Thomas are subject to an aggregate maximum liability of $7.5 million and the Company has agreed to indemnify Mr. Thomas for claims made on his guaranties. The guaranties from the Company and Mr. Thomas are limited to certain
bad boy acts by the borrower or by the guarantors, including fraud, intentional misrepresentation, willful misconduct, Environmental Indemnity (as defined), misappropriation of Rents (as defined), or certain acts of insolvency by the
borrower, such as filing a bankruptcy petition.

|(4) | The senior mezzanine loan bears interest at a rate such that the weighted average of the rate on this loan and the rate on the mortgage loan secured by Two Commerce Square equals
9.2% per annum. The effective interest rate on this loan as of March 31, 2009 was 19.3% per annum. The loan may not be prepaid prior to August 9, 2009, and thereafter is subject to yield maintenance payments unless the loan is
prepaid within 60 days of maturity. The loan is secured by our ownership interest in the real estate entities that own Two Commerce Square.

|(5) | Interest at a rate of 10% per annum is payable currently, and additional interest of 5% per annum is deferred until maturity. The loan is subject to a prepayment penalty
in the amount of the greater of 3% of the principal amount or a yield maintenance premium. The loan is secured by our ownership interest in the real estate entities that own Two Commerce Square.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(6) | The interest rate as of March 31, 2009 was 2.8% per annum. The loan has a one-year extension option at our election, subject to us complying with certain loan covenants.
We were in compliance with these covenants as of March 31, 2009 and expect to be in compliance at the extension date. We expect to exercise our option to extend this loan. The loan is also subject to an extension fee of 0.25% of the total
commitment amount of the loan and at the lenders option, a written appraisal may be required. In the event the loan to value ratio exceeds 65%, we must pay down the outstanding principal to meet the 65% loan to value ratio. In addition, the
lender may require an additional $2.5 million principal paydown. We have guaranteed and promised to pay the principal, interest and any other sum payable under the loan in the event the borrower, a wholly-owned subsidiary of our Operating
Partnership, does not do so.

|(8) | We may borrow an additional $3.9 million under this construction loan. This loan has two six-month extension options at our election. The first and second extension options are each
conditioned on the closing of 100 residential units, which has occurred. The extension options are subject to exit fees equal to 0.5% of the outstanding principal balance and unfunded commitments and may be reduced to 0.25% if certain conditions are
met. We expect to exercise these options. The principal paydowns are also subject to an exit fee. The interest rate for this loan as of March 31, 2009 was 7.0%. This loan is nonrecourse to the Company, but the Company guarantees the payment of
interest on the loan during the term of the loan as it may be extended. Additionally, the Company has a construction completion guaranty.

5. Unsecured Loan

In October 2005, we purchased the entire interest of our unaffiliated partner in TPG-El Segundo Partners, LLC, of which $3.9 million was financed with an unsecured loan from the former noncontrolling partner.
Principal and accrued interest on this loan had a scheduled maturity of October 12, 2009. During the first quarter of 2009 we paid down $2.05 million, including principal and interest, and as of March 31, 2009, the outstanding principal
balance was approximately $1.95 million and there was $0.1 million in accrued interest payable. We recognized $0.5 million gain on early extinguishment of debt related to this loan. The second and final installment of principal and interest of $2.05
million was paid on April 3, 2009.

6. Earnings (Loss) per Share and Dividends Declared

On January 1, 2009, the Company adopted FASB Staff Position EITF 03-6-1,Determining Whether Instruments Granted in Share-Based Payment Transactions
Are Participating Securities (FSP 03-6-1), which addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in earnings allocation in
computing basic earnings per share under the two-class method. The Company has adjusted its calculation of basic and diluted earnings per share to conform to the guidance provided in FSP 03-06-1, which also required retrospective application for all
periods presented. The change in calculating basic and diluted earnings per share pursuant to the adoption of FSP 03-6-1 did not have a material effect on the amounts previously reported for the periods presented (with the exception of the amount of
weighted-average basic and diluted shares utilized in the calculation).

The two-class method is an earnings allocation method for
calculating earnings per share when a companys capital structure includes either two or more classes of common stock or common stock and participating securities. Basic earnings per share under the two-class method is calculated based on
dividends declared on common shares and other participating securities (distributed earnings) and the rights of participating securities in any undistributed earnings, which represents net income remaining after deduction of dividends
accruing during the period. The undistributed earnings are allocated to all outstanding common shares and participating securities based on the relative percentage of each security to the total number of outstanding participating securities. Basic
earnings per share represents the summation of the distributed and undistributed earnings per share class divided by the total number of shares.

As of and through March 31, 2009, the Company has accrued and paid dividends in excess of net income, resulting in no undistributed earnings, as defined under the two-class method. In addition, all of the Companys participating
securities (including the incentive units) receive dividends/distributions at an equal dividend/distribution rate per share/unit. As a result, the portion of net income (loss) allocable to the weighted-average restricted stock outstanding for the
three months ended March 31, 2009 and 2008 has been deducted from net income allocable to common stockholders to calculate basic earnings/(loss) per share. The calculation of diluted earnings (loss) per share for the three months ended March 31,
2009 and 2008 includes the outstanding Units (both vested and unvested) and restricted stock in the weighted-average shares, as well as an increase to net income (loss) allocable to common stockholders for the noncontrolling interest charge
recognized during the respective period. No other shares were considered antidilutive for the three months ended March 31, 2009 and 2008.

The following is a summary of the components used in calculating basic and diluted earnings per share for the three months ended March 31, 2009 and 2008 (in thousands except share and per share amounts):

7. Stockholders Equity

A Unit and a share of our common stock have essentially the same economic characteristics as they share equally in the total net income or loss and distributions of the Operating Partnership. A Unit may be redeemed by the holder in exchange
for cash or shares of common stock at our election, on a one-for-one basis. We have issued 1,303,336 incentive units to certain employees. Incentive units represent a profits interest in the Operating Partnership and generally will be treated as
regular Units in the Operating Partnership and rank pari passu with the Units as to payment of distributions, including distributions of assets upon liquidation. Incentive units are subject to vesting, forfeiture and additional restrictions on
transfer as may be determined by us as general partner of the Operating Partnership. The holder of an incentive unit has the right to convert all or a part of his vested incentive units into Units, but only to the extent of the incentive units
economic capital account balance. As general partner, we may also cause any number of vested incentive units to be converted into Units to the extent of the incentive units economic capital account balance. We had 25,693,354 shares of common
stock, of which 1,429,450 were unregistered, and 13,813,331 Units outstanding as of March 31, 2009, and 512,221 incentive units outstanding which were issued under our Incentive Plan, defined below. The 1,429,450 unregistered shares were issued
in connection with the redemption of 746,115 vested incentive units and 683,335 Operating Partnership Units by executives. The share of the Company owned by the Operating Partnership unitholders is reflected as a separate component called
noncontrolling interests in the equity section of our consolidated balance sheets. As of March 31, 2009 and December 31, 2008, we held a 65.0% and 61.0% interest in the Operating Partnership, respectively.

We adopted the 2004 Equity Incentive Plan of Thomas Properties Group, Inc. as amended, (the Incentive Plan) effective upon the closing of our
initial public offering and amended it in May 2007 and June 2008 to increase the shares reserved under the plan. The Incentive Plan provides incentives to our employees and is designed to attract, reward and retain personnel. Our Incentive Plan
permits the granting of awards in the form of options to purchase common stock, restricted shares of common stock and restricted incentive units in our Operating Partnership. We may issue up to 3,361,906 shares as either stock option awards,
restricted stock awards or incentive unit awards. In addition, under our Non-Employee Directors Restricted Stock Plan (the Non-Employee Directors Plan) a total of 60,000 shares are reserved for grant.

Shares of newly issued common stock will be issued upon exercise of stock options.

Restricted Stock

Under the Incentive Plan, we have issued the following restricted shares to
Mr. Thomas and other executives:

Vesting for the 100,000 and 100,000 shares commenced as of March 7, 2007 and March 19,
2008, respectively. The restricted shares will vest in full on the third anniversary of the vesting commencement date, provided that vesting could occur on the second anniversary of the vesting commencement date if certain performance goals are met.
Mr. Thomas has full voting rights and will receive any dividends paid.

Under the Incentive Plan, in January 2009 we issued an
additional 410,000 restricted shares to certain executives which vest over the next five years, fifty percent are performance vested shares and fifty percent are discretionary vested shares.

The 5,968 shares granted will vest subject to the continued service of the directors up to and
through the 2009 Annual Meeting of Stockholders. The holders of these shares have full voting rights and will receive any dividends paid.

As of March 31, 2009, there was $2,136,000 of total unrecognized compensation cost related to the nonvested restricted stock under both the Incentive Plan and Non-Employees Directors Plan. The cost is expected to be recognized over a
weighted average period of 2.2 years. The weighted-average grant date fair value of restricted stock granted during the three months ended March 31, 2009 was $2.87 per share.

We recorded compensation expense totaling $354,000 and $223,000 for the vesting of the restricted stock grants for the three months ended March 31,
2009 and 2008, respectively. The total income tax benefit recognized in the statement of operations related to this compensation expense was $150,000 and $96,000 for the three months ended March 31, 2009 and 2008, respectively.

Incentive Units

Under our Incentive Plan, we issued
to certain executives 730,003 incentive units upon consummation of our initial public offering in October 2004, which fully vested on October 13, 2007. In February 2006 we issued 120,000 incentive units to certain executives, which units will
vest on the third anniversary of the grant date. In March 2007 we issued an additional 183,336 incentive units to certain executives, which units vest over a three year period, with one third vesting each on the first, second, and third anniversary
dates of the grant. In March 2008 we issued an additional 160,000 incentive units to certain executives, which units vest over a three year period, with one third vesting each on the first, second, and third anniversary dates of the grant. In
September 2008 we issued an additional 110,000 incentive units to a new executive, which vest over a three to five year period and are subject to market based performance measures as well as individual and Company goals.

For the three months ended March 31, 2009 and 2008, we recorded compensation expense of $554,000 and $482,000, respectively, relating to the
incentive units. As of March 31, 2009, there was $1,475,000 of unrecognized compensation cost related to incentive units.

Stock options

Under our Incentive Plan, we have 670,609 stock options outstanding as of March 31, 2009. The options vest at the rate of one
third per year over three years and expire ten years after the date of commencement of vesting. The fair market value of each option granted was estimated on the date of the grant using the Black-Scholes option pricing model with the following
weighted-average assumptions for grants in 2008.

As of March 31, 2009, there was $83,000 of total unrecognized compensation cost related to
the nonvested stock options. The cost is expected to be recognized over a weighted average period of 1.3 years. There were no options granted or exercised during the three months ended March 31, 2009.

We recorded compensation expense totaling $30,000 and $42,000 related to the stock options for the three months ended March 31, 2009 and 2008,
respectively. The total income tax benefit recognized in the statement of operations related to this compensation expense was $13,000 and $18,000 for the three months ended March 31, 2009 and 2008, respectively.

Noncontrolling Interests

On January 1, 2009, the
Company adopted SFAS 160, which clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. SFAS 160 also requires
consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and requires disclosure, on the face of the consolidated statement of income, of the amounts of consolidated
net income attributable to the parent and to the noncontrolling interest. In addition, SFAS 160 establishes a single method of accounting for changes in a parents ownership interest in a subsidiary that does not result in deconsolidation and
requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. As a result of the issuance of SFAS 160, the guidance in EITF Topic D-98,Classification and Measurement of Redeemable Securities, was
amended to include redeemable noncontrolling interests within its scope. If noncontrolling interests are determined to be redeemable, they are to be carried at their redemption value as of the balance sheet date and reported as temporary equity.

Noncontrolling interests on our consolidated balance sheets relate primarily to the partnership and incentive units in the Operating
Partnership (collectively, the Incentive Units) that are not owned by the Company. In conjunction with the formation of the Company, certain persons and entities contributing interests in properties to the Operating Partnership received
partnership units. In addition, certain employees of the Operating Partnership received incentive units in connection with services rendered or to be rendered to the Operating Partnership. Limited partners who have been issued incentive units have
the right to require the Operating Partnership to redeem part or all of their incentive units upon vesting of the Units, if applicable. The Company may elect to acquire those incentive units in exchange for shares of the Companys common stock
on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events, or pay cash based upon the fair market value of an equivalent number of
shares of the Companys common stock at the time of redemption.

SFAS 160 was required to be applied prospectively after adoption,
with the exception of the presentation and disclosure requirements, which were applied retrospectively for all periods presented. The Company has evaluated the terms of the Units and, as a result of the adoption of SFAS 160, the Company reclassified
noncontrolling interests to permanent equity in the accompanying consolidated balance sheets and recorded a decrease to the carrying value of noncontrolling interests of approximately $8.6 million (a corresponding increase was recorded to additional
paid-in capital) to reflect the noncontrolling interests proportionate share of equity at March 31, 2009. In periods subsequent to the adoption of SFAS 160, the Company will periodically evaluate individual noncontrolling interests for the
ability to continue to recognize the noncontrolling interest as permanent equity in the consolidated balance sheets. Any noncontrolling interest that fails to qualify as permanent equity will be reclassified as temporary equity and adjusted to the
greater of (a) the carrying amount, or (b) its redemption value as of the end of the period in which the determination is made.

The
redemption value of the incentive units not owned by the Company at March 31, 2009 was approximately $0.6 million based on the closing price of the Companys common stock of $1.18 per share as of March 31, 2009.

A charge is recorded each period to the consolidated statements of income (loss) for the noncontrolling interests proportionate share of the
Companys net income (loss). An additional adjustment is made each period such that the carrying value of the noncontrolling interests equals the greater of (a) the noncontrolling interests proportionate share of equity as of the period
end, or (b) the redemption value of the noncontrolling interests as of the period end, if classified as temporary equity.

Equity is
allocated between controlling and noncontrolling interests as follows (in thousands) :

8. Income Taxes

All operations are carried on through the Operating Partnership and its subsidiaries. The Operating Partnership is not subject to income tax, and all of the taxable income, gains, losses, deductions and credits are
passed through to its partners. We are responsible for our share of taxable income or loss of the Operating Partnership allocated to us in accordance with the Operating Partnerships Agreement of Limited Partnership. As of March 31, 2009,
we held a 63.7% capital interest in the Operating Partnership. For the three months ended March 31, 2009, we were allocated a blended rate of 64.0% of the income and losses from the Operating Partnership.

Prior to the adoption of SFAS No. 160 on January 1, 2009, income from noncontrolling interests was deducted from earnings before arriving at
income from continuing operations. With the adoption of SFAS No. 160, the income from noncontrolling interests has been reclassified below net income and therefore is no longer deducted in arriving at income from continuing operations. However,
the provision for income taxes does not change because the Operating Partnership and its subsidiaries with noncontrolling interests pay no income tax, but distribute taxable income to their respective investors. Accordingly, the Company will not pay
tax on the income attributable to the noncontrolling interests. As a result of separately reporting income that is taxed to others, the Companys effective tax rate on continuing operations before income taxes, as reported on the face of the
financial statements is 11.43% and 38.09% for the three months ended March 31, 2009 and 2008, respectively. However, the actual effective tax rate that is attributable to the Companys share of (loss) income from continuing operations
before income taxes (income from continuing operations before income taxes, as presented on the face of the income statement, less income (loss) from continuing operations attributable to noncontrolling interests of $1.487 million and ($306,000) for
the three months ended March 31, 2009 and 2008, respectively) is 4.87% for the three months ended March 31, 2009, as compared to 59.57% for the three months ended March 31, 2008. While the adoption of SFAS No. 160 does change the
location of net income attributable to noncontrolling interests on the statement of income, it does not change the income tax from interests owned by the Company.

The resulting effective tax rate of 11.43% on the face of the financial statements for the three months ended March 31, 2009, compared to the federal statutory rate of 35% is primarily due to the
amortization of the incentive units granted, the noncontrolling interests attributable income as a result of our adoption of SFAS No. 160, and the interest expense recorded during the quarter related to the Companys unrecognized tax
benefits.

The provision for income taxes is based on reported income before income taxes. Deferred income tax assets and liabilities
reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amount recognized for tax purposes, as measured by applying the currently enacted tax laws.

FASB Statement No. 109, Accounting for Income Taxes (SFAS No. 109), requires that deferred tax assets be reduced by a valuation
allowance if it is more likely than not that some or all of the deferred tax asset will not be realized. Realization of the deferred tax asset is dependent on us generating sufficient taxable income in future years as the deferred income tax charges
become currently deductible for tax reporting purposes. Although realization is not assured, management believes that it is more likely than not that the net deferred income tax asset will be realized.

Financial Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48) clarifies the accounting for uncertainty in income
taxes recognized in a companys financial statements in accordance with SFAS No. 109. The interpretation prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax
position taken or expected to be taken in a tax return. The interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

##### Table of Contents

The Companys policy is to recognize interest and penalties related to unrecognized tax benefits as
a component of income tax expense. For the three months ended March 31, 2009, we recorded $176,000 ($115,000, net of federal benefit), of interest related to unrecognized tax benefits as a component of income tax expense.

For the three months ended March 31, 2009, the Company has recorded $1.6 million of accrued interest with respect to unrecognized tax benefits. We
have not recorded any penalties with respect to unrecognized tax benefits.

We do not anticipate any significant increases or decreases to
the amounts of unrecognized tax benefits within the next twelve months.

9. Fair Value of Financial Instruments

SFAS No. 107, Disclosures about Fair Value of Financial Instruments, requires us to disclose fair value information about all financial instruments,
whether or not recognized in the balance sheets, for which it is practicable to estimate fair value.

Our estimates of the fair value of
financial instruments as of March 31, 2009 were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different
market assumptions or estimation methods may have a material effect on the estimated fair value amounts.

The carrying amounts for cash and
cash equivalents, restricted cash, rent and other receivables, due from affiliate, accounts payable and other liabilities approximate fair value due to the short-term nature of these instruments.

As of March 31, 2009, the fair value of our mortgage and other secured loans and unsecured loan aggregates $367.0 million, compared to the aggregate
carrying value of $392.5 million.



|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. This report
includes statements that are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this report entitled Forward-Looking Statements.
Certain risks may cause our actual results, performance or achievements to differ materially from those expressed or implied by the following discussion. For a discussion of such risks, see the section in this report entitled Risk
Factors.

When you read the financial statements and the information included in this report, you should be aware that our operations
are significantly affected by both macro and micro economic forces. Our operations are directly affected by actual and perceived trends in various national and regional economic conditions that affect national and regional markets for commercial
real estate services, including interest rates, the availability of credit to finance commercial real estate transactions, and the impact of tax laws affecting real estate. Periods of economic slowdown or recession, rising interest rates, tightening
of the credit markets, declining demand for or increased supply of real estate, or the public perception that any of these events may occur can adversely affect our business. These conditions could result in a general decline in rents, which in turn
would reduce revenue from property management fees and brokerage commissions derived from leases. In addition, these conditions could lead to a decline in property values as well as a decline in funds invested in commercial real estate and related
assets, which in turn may reduce revenues from investment advisory, property management, leasing and development fees.

Forward-Looking Statements

Forward-looking statements are subject to numerous risks and uncertainties that could cause actual results to differ materially from those
anticipated and you should not rely on them as predictions of future events. Although information is based on our current estimations, forward-looking statements depend on assumptions, data or methods which may be incorrect or imprecise. You are
cautioned not to place undue reliance on this information as we cannot guarantee that any future expectations and events described will happen as described or that they will happen at all. You can identify forward-looking statements by the use of
forward-looking terminology such as believes, expects, may, should, seeks, approximately, intends, plans, pro forma, estimates or
anticipates or the negative of these words and phrases or similar words or phrases. You can also identify forward-looking statements by discussions of strategy, plans or intentions.

Overview and Background

We are a full-service real
estate operating company that owns, acquires, develops and manages primarily office, as well as mixed-use and residential properties on a nationwide basis. We conduct our business through our Operating Partnership, of which we own 65.0% as of
March 31, 2009 and have control over the major decisions of the Operating Partnership.

Comparison
of three months ended March 31, 2009 to three months ended March 31, 2008

Total revenues. Total revenues decreased by
$2.4 million, or 10.1%, to $21.3 million for the three months ended March 31, 2009 compared to $23.7 million for the three months ended March 31, 2008. The significant components of revenue are discussed below.

Rental revenues.Rental revenue decreased $0.4 million, or 5.1% to $7.4 million for the three months ended March 31, 2009 compared to
$7.8 million for the three months ended March 31, 2008. The decrease was primarily related to a scheduled expiration in June 2008 of a significant tenant at Two Commerce Square representing approximately 375,000 rentable square feet.
Approximately 66% of the space from the June 2008 Conrail lease expiration has been leased to former subtenants or new tenants at current market rates, which are lower than the expired lease rates.

Tenant reimbursements.Tenant reimbursements decreased $0.9 million, or 13%, to $6.0 million for the three months ended March 31, 2009
compared to $6.9 million for the three months ended March 31, 2008. The decrease was primarily related to a scheduled expiration in June 2008 of a significant tenant at Two Commerce Square representing approximately 375,000 rentable square
feet, offset by revenues from former subtenants or new tenants that are now direct tenants.

Parking and other revenues.Parking and other revenues decreased $0.2 million, or 20.0%, to $0.8
million for the three months ended March 31, 2009 from $1.0 million for the three months ended March 31, 2008. The decrease primarily related to transient parking revenue related to a special exhibition adjacent to our Commerce Square
property in 2008. There was no corresponding event in 2009.

Investment advisory, management, leasing and development services revenues.This caption represents revenues earned from services provided to unaffiliated entities in which we have no ownership interest. Revenues from these services remained consistent for each of the three month periods ended March 31, 2009 and
2008.

Investment advisory, management, leasing and development services revenues  unconsolidated real estate entities.This
caption represents revenues earned from services provided to entities in which we use the equity method to account for our ownership interest since we have significant influence, but not control, over the entities. Revenues from these services from
unconsolidated real estate entities decreased by $0.4 million, or 9.3%, from $4.3 million for the three months ended March 31, 2008 to $3.9 million for the three months ended March 31, 2009 primarily due to a decrease of $0.3 million in
lease commission revenue generated from the Austin Portfolio Joint Venture Properties for the three months ended March 31, 2009 compared to the three months ended March 31, 2008 due to decreased leasing activity. Additionally, we had
decreased development activity at Brookhollow and City National Plaza offset by increased development activity in the Austin Portfolio Joint Venture Properties, resulting in a net decrease in development fees of $0.1 million for the three months
ended March 31, 2009 compared to the three months ended March 31, 2008.

Reimbursement of property personnel costs. This
caption represents the reimbursement for property personnel salary, payroll taxes and benefits. The decrease of $0.4 million or 20% to $1.6 million for the three months ended March 31, 2009 compared to $2.0 million for the three months ended
March 31, 2008 was primarily due to compensation related reductions as a result of cost saving measures implemented in the fourth quarter of 2008.

Total expenses.Total expenses increased by $3.0 million, or by 12.6%, to $26.9 million for the three months ended March 31, 2009 compared to $23.9 million for the three months ended March 31, 2008.
The significant components of expense are discussed below.

Property operating and maintenance expense.Property operating and
maintenance remained consistent for each of the three month periods ended March 31, 2009 and 2008.

Real estate taxes.Real
estate taxes remained consistent for each of the three month periods ended March 31, 2009 and 2008.

Investment advisory,
management, leasing and development services expenses.Expenses for these services decreased by $0.3 million, or 9.4%, to $2.9 million for the three months ended March 31, 2009 compared to $3.2 million for the three months ended
March 31, 2008, primarily as a result of certain cost saving measures implemented in the fourth quarter of 2008.

Reimbursable
property personnel costs. This caption represents the reimbursement of property personnel salary, payroll taxes and benefits. The decrease of $0.4 million or 20% to $1.6 million for the three months ended March 31, 2009 compared to $2.0
million for the three months ended March 31, 2008 was primarily due to compensation related reductions as a result of cost saving measures implemented in the fourth quarter of 2008.

Cost of condominium sales.This caption represents the cost recognized on the percentage of completion method of accounting for the Murano
condominium units and parking spaces which closed or were under a binding sales contract as of March 31, 2009. As of March 31, 2009, we had closed on the sale of 112 condominium units and 108 parking spaces at Murano, a 302-unit high rise
residential condominium project in downtown Philadelphia. We had an additional 13 units and 11 parking spaces under contract of sale as of March 31, 2009. We did not recognize any revenue in the quarter ended March 31, 2009 as we had no
condominium and parking space sales, therefore we incurred a nominal cost of sales amount.

Rent  unconsolidated entities.Rent  unconsolidated entities remained consistent for each of the three month periods ended March 31, 2009 and 2008.

Interest expense.Interest expense increased by $2.7 million, or 65.9%, to $6.8 million for the three month period ended March 31, 2009 from $4.1 million for the three month period ended March 31, 2008. The increase in
interest expense is primarily attributable to interest costs no longer being capitalized on Murano and our Four Points office buildings due to the substantial completion of development on these projects in the second half of 2008.

Depreciation and amortization expense.Depreciation and amortization expense increased by $0.4 million or 14.3% to $3.2 million for the three
months ended March 31, 2009 compared to $2.8 million for the three months ended March 31, 2008 due to normal activity at Commerce Square.

General and administrative.General and administrative expense increased by $0.3 million, or 7.3%,
to $4.4 million for the three months ended March 31, 2009 compared to $4.1 million for the three months ended March 31, 2008. The increase was primarily a result of an increase in non-cash incentive compensation costs related to grants
made to an executive hired in 2008 and certain professional fees.

Gain on sale of real estate.Gain on sale of real estate
decreased by $2.5 million, or 100%, for the three months ended March 31, 2009 from $2.5 million for the three months ended March 31, 2008 due to the full recognition of deferred gain in 2008 upon completion of infrastructure costs related
to the sale of a 14.1 acre parcel at Campus El Segundo in 2006.

Interest income.Interest income decreased by $1.0 million, or
90.9%, to $0.1 million for the three months ended March 31, 2009 compared to $1.1 million for the three months ended March 31, 2008 primarily due to declining investment balances and lower interest rates.

Aggregate revenue increased due to an increase in occupancy for the three months ended
March 31, 2009 compared to the three months ended March 31, 2008. Aggregate operating and other expenses for unconsolidated real estate entities for the three months ended March 31, 2009 compared to the three months ended
March 31, 2008 remained consistent. Interest expense for the three months ended March 31, 2009 compared to the three months ended March 31, 2008 decreased primarily due to declining interest rates. Depreciation and amortization for
unconsolidated real estate entities decreased for the three months ended March 31, 2009 compared to the three months ended March 31, 2008 primarily due to normal activity. Gain on early extinguishment of debt for the three months ended
March 31, 2009 was due to the Austin Portfolio Term loan for which the Company was able to negotiate a discounted partial payoff.

Benefit (provision) for income taxes. Provision for income taxes decreased by $0.5 million to a benefit of $0.2 million for the three months ended March 31, 2009 compared to a provision of $0.3 million for the three months ended
March 31, 2008. The decrease was primarily due to the Companys loss from continuing operations of $1.9 million for the three months ended March 31, 2009, compared to income from continuing operations of $0.8 million for the three months ended
March 31, 2008. Additionally, as a result of our adoption of SFAS No. 160, the measurement of our effective tax rate has changed from previous periods.

Liquidity and Capital Resources

Analysis of liquidity and capital resources

As of March 31, 2009, we have unrestricted cash and cash equivalents of $61.0 million. Our management believes that our company will have sufficient
capital to satisfy our liquidity needs over the next 12 months through working capital and net cash provided by operations. We expect to meet our long-term liquidity requirements, including property and undeveloped land acquisitions and additional
future development and redevelopment activity, through cash flow from operations, additional secured and unsecured long-term borrowings, dispositions of non-strategic assets, and the potential issuance of common units of our Operating Partnership or
additional debt, common or preferred equity securities, including convertible securities. We do not have any present intent to reserve funds to retire existing debt upon maturity. We will instead seek to refinance this debt at maturity or retire the
long-term debt through the issuance of securities, as market conditions permit. There can be no assurances that such debt refinancing will be available at the time of such maturities on acceptable terms, if at all, and our cost of capital could
increase as a result of any such debt refinancings. Additionally, existing stockholders could experience substantial dilution in the event we are required to issue additional equity capital.

As of March 31, 2009, we have unfunded capital commitments to (1) our joint venture with CalSTRS of $4.1 million; (2) the Thomas High
Performance Green Fund, an investment fund formed by us, CalSTRS and other institutional investors, of $50.0 million; and (3) the UBS North American Property Fund, an investment fund formed by us and UBS Wealth Management-North American
Property Fund Limited, of $50.0 million. With respect to our joint venture with CalSTRS, we are not obligated to fund our share of the capital commitment for the acquisition of any new project, but we are obligated to fund to implement tenant
improvements and other capital improvements for projects that were acquired prior to June 1, 2007. We estimate we will fund the entire $4.1 million in 2009.

##### Table of Contents

Our requirement to fund all or a portion of our commitments to the Thomas High Performance Green Fund and the UBS North American Property Fund is subject to
our identifying properties to acquire that are mutually acceptable to us, and our partners. Our cash requirements for the Green Fund could be reduced by contributions by us to the fund of assets in which we have an interest.

We intend to declare and pay annual dividends on our common stock. The availability of funds to pay dividends is impacted by property-level restrictions
on cash flows. Two Commerce Square is subject to debt financing with lock-box arrangements. Funds generated by Two Commerce Square cannot be distributed to us under the terms of the lock-box arrangements established for the existing lenders for the
property. In addition, all of our properties held in our joint venture with CalSTRS are subject to debt financing with a lockbox arrangements. With respect to our joint venture properties, we do not solely control decision making with respect to
these properties, and may not be able to obtain monies from these properties even if funds are available for distribution to us. In addition, we may enter future financing arrangements that contain restrictions on our use of cash generated from our
properties.

Development and Redevelopment Projects

We currently own interests in four development projects (some of which are discussed below), and our joint venture with CalSTRS includes four redevelopment properties and two development sites.

We have substantially completed construction and received certificates of occupancy for all of the units at Murano, a 302-unit high-rise residential
condominium project in downtown Philadelphia. We have closed sales on 112 units and 108 parking spaces as of March 31, 2009 and have an additional 13 units and 11 parking spaces under contract of sale. Under the percentage-of-completion method
of accounting, we recognized a gain on sale of approximately $17.3 million for the year ended December 31, 2008. Due to the deteriorating market conditions, in the second half of 2008, we recorded an $11.0 million impairment charge. There were
no sales related to the Murano in the three months ended March 31, 2009. Murano is classified as Condominium units held for sale on our balance sheet as of March 31, 2009.

We anticipate seeking to mitigate our development risk on all of our development projects by obtaining significant pre-leasing and guaranteed maximum
cost construction contracts. There can be no assurance we will be able to successfully implement these risk mitigation measures.

The
amount and timing of costs associated with our development and redevelopment projects is inherently uncertain due to market and economic conditions. We presently intend to fund development and redevelopment expenditures primarily through
construction or refurbishment financing. Construction of the Murano was financed in part with a construction loan up to $142.5 million. Repayment of this loan is being made with proceeds from the sales of condominium units. The loan has a balance of
$69.6 million as of March 31, 2009 and we had additional borrowing capacity of $3.9 million. The completed core and shell construction of two office buildings at our development site at Four Points was financed in part with a construction loan,
which has an outstanding balance as of March 31, 2009 of $29.4 million with additional borrowing capacity of $13.3 million to fund tenant improvement costs. Presently, we have not obtained construction financing for the development at Campus El
Segundo. If we finance these development projects through construction loans and are unable to obtain permanent financing on advantageous terms or at all, we would need to fund these obligations from cash flow from operations or seek alternative
capital sources. If unsuccessful, this could adversely impact our financial condition and results of operations and impair our ability to satisfy our debt service obligations. If we are successful in obtaining construction or refurbishment financing
and permanent financing, we anticipate that the corresponding interest costs would represent both a significant use of our cash flow and a material component of our results of operations.

We are also involved in managing two entitlement projects, which are discussed below:



| |  |  | We are presently entitling approximately 14.4 acres in Los Angeles, California, for office, production facility, residential and retail uses. The project, called
Metro Studio@Lankershim, will include approximately 1.5 million square feet. Upon completion of entitlements, we expect to enter into a long-term ground lease with the Los Angeles County Metropolitan Transportation Authority, which owns the
land.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Also, we have been engaged by NBC/Universal to entitle, master plan and develop (subject to our right of first offer) 124 acres located adjacent to Universal City
in Los Angeles for the development of a residential and retail town center. We anticipate completing the development of these projects as market feasibility permits.

Leasing, Tenant Improvement and Capital Needs

In addition to our development and redevelopment
projects, we also own One Commerce Square and Two Commerce Square. These properties require routine capital maintenance in the ordinary course of business. The properties also require that we incur expenditures for leasing commissions and tenant
improvement costs. The level of these expenditures varies from year to year based on several factors, including lease expirations. We are contractually committed to incur expenditures of approximately $6.3 million in capital improvements, tenant
improvements, and leasing commissions for the One Commerce Square and Two Commerce Square properties, collectively, during 2009 through 2010.

##### Table of Contents

Annual capital expenditures may fluctuate in response to the nature, extent and timing of improvements
required to maintain our properties. Tenant improvements and leasing costs may also fluctuate depending upon other factors, including the type of property involved, the existing tenant base, terms of leases, types of leases, the involvement of
leasing agents and overall market conditions.

|(1) | The debt maturing in 2009 includes the Campus El Segundo mortgage loan in the amount of $17.0 million. This loan has a one-year extension option at our election subject to us
complying with certain loan covenants. We were in compliance with these covenants as of March 31, 2009 and expect to be in compliance at the extension date. We expect to exercise our option to extend this loan. The lender may require an
additional $2.5 million principal paydown in October 2009. We have guaranteed and promised to pay the principal, interest and any other sum payable under the loan in the event the borrower, a wholly-owned subsidiary of our Operating Partnership,
does not do so. On April 3, 2009, we paid the remaining $2.05 million of debt maturing in 2009, which was due to our former partner in our Campus El Segundo development. We recognized a gain of $0.5 million on early extinguishment of debt
in the first quarter of 2009.

|(2) | In January 2010, $36.0 million in nonrecourse senior and junior mezzanine loans secured by our ownership interest in Two Commerce Square mature. We will seek to extend or refinance
this debt at maturity. The Four Points Centre construction loan in the amount of $29.4 million matures in June 2010. This loan has two one-year extension options at our election subject to certain conditions. The first extension option is
subject to completion of the improvements and executed leases representing at least 75% of the net rentable area, among other things. The second extension option is subject to completion of improvements, executed leases representing at least 90% of
the net rentable area, and a minimum debt yield, among other things. We have guaranteed in favor of and promised to pay to the lender 46.5% of the principal, interest and any other sum payable under the loan in the event the borrower, a wholly-owned
subsidiary of our Operating Partnership, does not do so. This guaranty is currently limited to a maximum of $13.7 million. In addition, the Company may be required to contribute up to $2.225 million in additional equity on or after June 8,
2009, at the lenders request. Upon the occurrence of certain events, as defined in the repayment and completion guaranty agreement, our maximum liability as guarantor will be reduced to 31.5% of all sums payable under the loan, and upon the
occurrence of even further events, as defined, our maximum liability as guarantor will be reduced to 25.0% of all sums payable under the loan. Furthermore, we agreed to guarantee the completion of the construction improvements, as defined in the
agreement, in the event of any default of the borrower. We have completed construction of the core and shell. If the borrower fails to complete the required work, the guarantor agrees to perform timely all of the completion obligations, as defined
in the agreement. In addition, the Murano construction loan has a balance of $69.6 million as of March 31, 2009 with a maturity date of July 31, 2009, however it has two six-month extension options, which are conditional on the closing of
100 residential units, which has occurred and therefore we expect to exercise these options, and extend the maturity date to July 31, 2010. This loan is nonrecourse to the Company but the Company guarantees the payment of interest on the loan
during the term of the loan as it may be extended. Additionally, the Company has a construction completion guaranty. We amortize the principal balance of the Murano construction loan with sales proceeds as we close on the sale of condominium units.

|(3) | As of March 31, 2009, 70.4% of our debt was at contractually fixed rates. The information in the table above reflects our projected interest rate obligations for the fixed-rate
payments based on the contractual interest rates and scheduled maturity dates. The remaining 29.6% of our debt bears interest at variable rates based on the prime rate or LIBOR plus a spread that ranges from 1.5% to 3.3%. The interest payments on
the variable rate debt have not been reported in the table above because we cannot reasonably determine the future interest obligations on our variable rate debt as we cannot predict what prime and LIBOR rates will be in the future. As of
March 31, 2009, the one-month LIBOR was 0.50% and the prime rate was 3.25%.

##### Table of Contents

|(4) | Capital commitments of our company and consolidated subsidiaries include approximately $6.3 million of tenant improvements and leasing commissions for certain tenants in One
Commerce Square and Two Commerce Square. We have an unfunded capital commitment of $4.1 million to our TPG/CalSTRS joint venture, which we estimate we will fund the entire amount in 2009. We are not obligated to fund our share for the acquisition of
any new project, but we are obligated to fund to implement tenant improvements and other capital improvements for projects that were acquired prior to June 1, 2007.

The lease expires in May 2009 and we are in discussions to extend based on market rates.

|(6) | The FIN 48 obligations in the table above should represent amounts associated with uncertain tax positions related to temporary differences. However, reasonable estimates cannot be
made about the amount and timing of payment for these obligations. As of March 31, 2009, $17.3 million of unrecognized tax benefits have been recorded as liabilities in accordance with FIN 48, and we are uncertain as to if and when such amounts
may be settled. Included within the unrecognized tax benefits is $1.6 million of accrued interest. We have not recorded any penalties with respect to unrecognized tax benefits.

Off-Balance Sheet Arrangements  Indebtedness of Unconsolidated Real Estate Entities

As of March 31, 2009, our company had investments in entities owning unconsolidated properties with stated ownership percentages ranging from 6.25%
to 50.0%. We do not have sole control of these entities, and none of the entities are considered variable interest entities. Therefore, we account for them using the equity method of accounting. The table below summarizes the outstanding debt for
the properties as of March 31, 2009 (in thousands). None of these loans are recourse to us other than as noted in footnote 12 below.

|(18) | During the quarter, TPG-Austin Portfolio Holdings LP entered into agreements pursuant to which (i) the prior $100 million Revolving Loan was terminated, (ii) a senior
secured priority facility of $60 million was created which a subsidiary of TPG/CalSTRS agreed to fund 25% on a pari passu basis with affiliates of Lehman Brothers and a sovereign wealth fund that are partners in the Austin Portfolio Joint
Venture, and (iii) the venture purchased and retired $80 million of the bank term loan at a discount to face value, reducing that loan from $192.5 million to $112.5 million. The new $60 million priority facility is senior in payment and right
to the collateral to the bank term loan. The senior secured priority credit facility bears interest at 10% per annum on the first $24 million, 15% per annum on the next $12 million and 20% per annum on the last $24 million. This
restructure resolved the claims of the Austin Portfolio Joint Venture against Lehman arising from Lehmans failure to fund the $100 million revolving loan.

Cash Flows

Comparison of three months ended March 31, 2009 to three months ended March 31. 2008.

Cash and cash equivalents
(including restricted cash) were $61.0 million as of March 31, 2009 and $107.4 million as of March 31, 2008.

Operating
Activities - Net cash used in operating activities increased by $3.5 million to $(12.0) million for the three months ended March 31, 2009 compared to $(8.5) million for the three months ended March 31, 2008. The decrease was primarily the
result of a decrease in accounts payable.

Investing Activities - Net cash used in investing activities decreased by $33.4 million to
$(1.9) million for the three months ended March 31, 2009 compared to $(35.3) million for the three months ended March 31, 2008. The decrease was primarily the result of $1.0 million in proceeds from sales of our Murano condominium units
for the three months ended March 31, 2009, offset by a capital contribution of $(1.25) million to the Austin Portfolio Joint Venture Properties. In addition, an increase of $33.3 million related to a decrease in capital expenditures on our
Murano, Four Points Center, Campus El Segundo and MetroStudio@Lankershim development projects.

Financing Activities - Net cash provided by
financing activities decreased by $18.7 million to $5.9 million for the three months ended March 31, 2009 compared to $24.6 million for the three months ended March 31, 2008. The decrease was primarily the result of decreased borrowings
totaling $24.5 million on our Murano and Four Points Center construction loans. This was offset by a $2.1 million increase in restricted cash and a $3.7 million increase due to a decrease in principal payments of mortgage loans.

Inflation

Substantially all of our office leases
provide for tenants to reimburse us for increases in real estate taxes and operating expenses related to the leased space at the applicable property. In addition, many of the leases provide for increases in fixed base rent. We believe that
inflationary increases may be partially offset by the contractual rent increases and expense reimbursements as described above. We have one multi-family residential rental property and are substantially complete with construction on Murano, a
high-rise residential tower in Philadelphia. The existing residential property is located in the Philadelphia central business district and subject to short-term leases. Inflationary increases can often be offset by increased rental rates; however,
a weak economic environment may restrict our ability to raise rental rates.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

A primary market risk faced by our company is interest rate risk. Our strategy is to match as closely as possible the expected holding periods and income streams of our assets with the terms of our debt. In general, we use floating rate
debt on assets with higher growth prospects and less stability to their income streams. Correspondingly, with respect to stabilized assets with lower growth rates, we will generally use longer-term fixed-rate debt. As of March 31, 2009, our
company had $116.0 million of outstanding consolidated floating rate debt, which is not subject to an interest rate cap.

The
unconsolidated real estate entities have total debt of $2.2 billion, of which $1.10 billion bears interest at floating rates. As of March 31, 2009, interest rate caps have been purchased for $1.05 billion of the floating rate loans.

Our fixed and variable rate consolidated long-term debt at March 31, 2009 consisted of the following (in thousands):

We utilize sensitivity analyses to assess the potential effect of our variable rate debt. At
March 31, 2009, our variable rate long-term debt represents 29.6% of our total long-term debt. If interest rates were to increase by 75 basis points, or by approximately 14.6% of the weighted average variable rate at March 31, 2009, the
net impact would be increased interest costs of $0.9 million per year.

As of March 31, 2009, the fair value of our mortgage and other
secured loans and unsecured loan aggregate $367.0 million, compared to the aggregate carrying value of $392.5 million.

|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Evaluation of Disclosure Controls and
Procedures

We have adopted and maintain disclosure controls and procedures that are designed to ensure that information required to be
disclosed in the reports that we file or submit under the Securities Exchange Act, as amended (the Exchange Act), is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities
and Exchange Commission (SEC) and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding
required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any 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.

As required by Rule 13a-15(b), promulgated by the SEC under the Exchange Act, we have carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer
and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial
Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized,
and reported within the time periods specified in the SECs rules and forms.

Changes in Internal Controls over Financial Reporting

There were no changes in our internal control over financial reporting as defined in Rules 13a-15(f) or 15(d)-15(f) under the Exchange Act that
occurred during the quarter ended March 31, 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls

Management does not expect that our disclosure controls and procedures or
our internal control over financial reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that
its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

We generate a significant portion of our revenues as a result of our relationships with CalSTRS. If we were to lose these relationships, our
financial results and growth prospects would be significantly negatively affected.

Our relationships with CalSTRS are a significant
factor in our ability to achieve our intended business growth. Our separate account and joint venture relationships with CalSTRS, including the Austin Portfolio Joint Venture in which we invested through our joint venture with CalSTRS, provide us
with substantial fee revenues. For the three months ended March 31, 2009, approximately 26.6%, of our revenue has been derived from fees earned from these relationships. We may also earn fee revenues in the future from the Green Fund as a
result of CalSTRS investment in that partnership.

We cannot assure you that our relationships with CalSTRS will continue and we may
not be able to replace these relationships with other strategic alliances that would provide comparable revenues. Our interest in TPG/CalSTRS is subject to a buy-sell provision, and is subject to purchase by CalSTRS upon the occurrence of certain
events. Under the buy-sell provision either our Operating Partnership or CalSTRS can initiate a buy-out by delivering a notice to the other specifying a purchase price for all the joint ventures assets; the other venture partner then has the
option to sell its joint venture interest or purchase the interest of the initiating venture partner. The purchase price is based on what each venture partner would receive on liquidation if the joint ventures assets were sold for the
specified price and the joint ventures liabilities paid and the remaining assets distributed to the joint venture partners. In addition, CalSTRS has the ability to initiate this provision upon certain events of default by us under the joint
venture agreement or related management and development agreements or upon bankruptcy of our Operating Partnership, or upon the death or disability of either James A. Thomas, our Chairman, President and CEO, or John R. Sischo, one of our
Executive Vice Presidents, or the failure of either of them to devote the necessary time to perform their duties (unless replaced by an individual approved by CalSTRS) (a Buyout Default), or upon any transfer of stock of our company or
limited partnership units in our Operating Partnership resulting in Mr. Thomas, his immediate family and controlled entities owning less than 30% of our securities entitled to vote for the election of directors. Upon the occurrence of a Buyout
Default by the Company, CalSTRS may elect to purchase our joint venture interest based on a three percent discount to the appraised fair market value.

Most of our fee arrangements under our separate account relationship with CalSTRS are terminable on 30
days notice. Termination of either our joint venture or separate account relationship with CalSTRS could adversely affect our revenue and profitability and our ability to achieve our business plan by reducing our fee income and access to
co-investment capital to acquire additional properties.

Our joint venture investments may be adversely affected by our lack of control or input on
decisions or shared decision-making authority or disputes with our co-venturers

We hold interests in each of our operating properties
in a joint venture or partnership. As a result, with the exception of One Commerce Square, Two Commerce Square, and the office buildings at Four Points Centre, we do not exercise sole decision-making authority regarding the property, joint venture
or other entity, including with respect to cash distributions or the sale of the property. Furthermore, we expect to co-invest in the future through other partnerships, joint ventures or other entities, acquiring non-controlling interests or in
sharing responsibility for managing the affairs of a property, partnership or joint venture. Investments in partnerships, joint ventures or other entities may, under certain circumstances, involve risks including partners who may have economic or
other business interests or goals which are inconsistent with our business interests or goals and may be in a position to take actions contrary to our policies or objectives. These investments may also have the risk of impasses on significant
decisions, because neither we nor our partner or co-venturer would have full control over the partnership or joint venture. Disputes between us and our partners or co-venturers may result in litigation or arbitration that would increase our expenses
and prevent our officers and/or directors from focusing their full time and effort on our business. In addition, under the principles of agency and partnership law, we may in certain circumstances be liable for the actions of our third-party
partners or co-venturers such as if a partner or co-venturer were to become bankrupt and default on its reimbursement and contribution obligations to us, were to subject property owned by the partnership or joint venture to liabilities in excess of
those contemplated by the partnership or joint venture agreement or were to incur debts or liabilities on behalf of the partnership or joint venture in excess of the authority otherwise granted by the partnership or joint venture agreement. In some
joint ventures or other investments we make, if the entity in which we invest is a limited partnership, we have acquired and may acquire in the future all or a portion of our interest in such partnership as a general partner. In such event, we may
be liable for all the liabilities of the partnership, although we attempt to limit such liability to our investment in the partnership by investing through a subsidiary.

Our joint venture partners have rights under our joint venture agreements that could adversely affect us.

As of March 31, 2009, we hold interests in 22 of our properties through TPG/CalSTRS, 10 of which are held indirectly through TPG/CalSTRS interest in the Austin Portfolio Joint Venture. TPG/CalSTRS requires a unanimous vote of the
joint ventures management committee on certain major decisions, including approval of annual business plans and budgets, financings and refinancings, and additional capital calls not in compliance with an approved annual plan. All other
decisions, including sales of properties, are made based upon a majority decision of the management committee, which currently consists of two members appointed by CalSTRS and one member appointed by us. Thus CalSTRS has the ability to control
certain decisions for the joint venture that may result in an outcome contrary to our interests. In addition to CalSTRS ability to control certain decisions relating to the joint venture, our joint venture agreement with CalSTRS includes
provisions negotiated for the benefit of CalSTRS that could adversely affect us. Unless otherwise determined by the management committee of the joint venture, we are required to use diligent efforts to sell each joint venture property generally
within five years of that property reaching stabilization, except that the holding period for Reflections I and Reflections II, both of which are 100% leased, will be separately determined by the joint venture management committee. With respect to
these two properties, we are required to perform a hold/sell analysis at least annually, and make a recommendation to the management committee regarding the appropriate holding period, which could be less than five years. We have a right of first
offer to purchase a joint venture property upon a required sale at a price we propose, and if CalSTRS accepts our offer we must close within 90 days. If we do not exercise the right of first offer and we subsequently fail to effect a sale by the end
of the specified holding period, CalSTRS has the right to assume control of the sale process. This may require us to sell a substantial portion of our assets at an inopportune time, or for prices that are lower than could be achieved if we had more
flexibility in the timing for effecting sales.

TPG/CalSTRS entered into a partnership agreement and syndication agreement with an
affiliate of Lehman Brothers, Inc. in relation to the Austin Portfolio Joint Venture. That agreement required us to assist the Lehman affiliate that was the primary equity holder in the joint venture with syndicating a substantial portion of the
entitys equity position by June of 2008. As of March 31, 2009, 33% of the Lehman affiliates original equity in the joint venture had been sold to an unrelated institutional investor. We and Lehman were unable to sell the Lehman
affiliates remaining equity to investors during the syndication period. As a result, the Lehman affiliate holds 50% of the equity in the joint venture as of March 31, 2009 and retains certain approval rights with respect to an expanded
set of major decisions of the joint venture, although we are still in charge of operating, leasing and managing the joint venture assets within approved budgets and guidelines. Also, the other limited partner in this partnership has approval rights
over such major decisions.

These rights include, but are not limited to, the right to approve annual business plans and budgets,
financings and refinancings, sales of properties, additional capital calls not in compliance with an approved annual plan, and agreements with affiliates. The limited partners also have the right to remove the general partner under certain
circumstances. These rights could adversely affect us.

We depend on significant tenants, and their failure to pay rent could seriously harm our
operating results and financial condition.

As of March 31, 2009, the 20 largest tenants for properties in which we hold an
ownership interest collectively leased 33.9% of the rentable square feet of space, representing 34.9% of the total annualized rent generated by these properties. Consolidated Rail Corporation, together with its wholly-owned subsidiary New York
Central Lines, LLC (Conrail), leases approximately 39.7% of the space at Two Commerce Square and accounted for approximately 1.6% of the total annualized rent generated by all of our consolidated and unconsolidated properties as of
March 31, 2009. In addition, Conrails rental revenues and tenant reimbursements accounted for approximately 16.1% of total consolidated revenue, on a United States generally accepted accounting principles (GAAP) basis, for the
three months ended March 31, 2009.

We rely on rent payments from our tenants as a source of cash to finance our business. Any of our tenants
may experience a downturn in its business that may weaken its financial condition. As a result, a tenant may delay lease commencement, fail to make rental payments when due, decline to extend a lease upon its expiration, become insolvent or declare
bankruptcy. In addition, current economic and market conditions increase the possibility that one or more of our tenants will become insolvent. Any tenant bankruptcy or insolvency, leasing delay or failure to make rental payments when due could
result in the termination of the tenants lease and material losses to our company.

In particular, if any of our significant tenants
becomes insolvent, suffers a downturn in its business and decides not to renew its lease or vacates a property, it may seriously harm our business. Failure on the part of a tenant to comply with the terms of a lease may give us the right to
terminate the lease, repossess the applicable property and enforce the payment obligations under the lease. In those circumstances, we would be required to find another tenant. We cannot assure you that we would be able to find another tenant
without incurring substantial costs, or at all, or that if another tenant were found, we would be able to enter into a new lease on favorable terms. We are not aware of an insolvency issue with any of our significant tenants.

Bankruptcy filings by or relating to one of our tenants could bar us from collecting pre-bankruptcy debts from that tenant or their property. A tenant
bankruptcy would delay our efforts to collect past due balances under the relevant leases, and could ultimately preclude full collection of these amounts. If a lease is assumed by the tenant in bankruptcy, all pre-bankruptcy amounts due under the
lease must be paid to us in full. However, if a lease is rejected by a tenant in bankruptcy, we would have only a general unsecured claim for damages. Any unsecured claim we hold against a bankrupt entity may be paid only to the extent that funds
are available and only in the same percentage as is paid to all other holders of unsecured claims. We may recover substantially less than the full value of any unsecured claims in the event of the bankruptcy of a large tenant, which would adversely
impact our financial condition. As of March 31, 2009, we are not aware of any tenant at our consolidated properties that has filed for bankruptcy protection.

Our operating results depend upon the regional economies in which our properties are located and the demand for office and other mixed-use space, and an economic downturn in these regions could harm our operating results.

Our operating and development properties are located in three geographic regions of the United States: the West Coast, Southwest and Mid-Atlantic
regions. Historically, the largest part of our revenues has been derived from our ownership and management of properties consisting primarily of office buildings. A decrease in the demand for office space in these geographic regions, and
Class A office space in particular, may have a greater adverse effect on our business and financial condition than if we owned a more diversified real estate portfolio. We are susceptible to adverse developments in these regions and in the
national office market, such as business layoffs or downsizing, industry slowdowns, relocations of businesses, changing demographics, terrorist targeting of high-rise structures, infrastructure quality, increases in real estate and other taxes,
costs of complying with government regulations or increased regulation and other factors, and oversupply of or reduced demand for office space. Some of the regional issues we face include the more highly regulated and taxed economy of Southern
California and high local and municipal taxes for our Philadelphia properties. Any adverse economic or real estate developments in a local region, or any decrease in demand for office space resulting from the local regulatory environment, business
climate or energy or fiscal problems, could adversely impact our revenue and profitability, thereby causing a significant downturn in our financial condition, results of operations, cash flow, the trading price of our common stock and impairing our
ability to satisfy our debt service obligations

Our debt service obligations reduce cash available to fund business growth and may expose us to the
risk of default under our debt obligations.

As of March 31, 2009, our total consolidated indebtedness is approximately $392.5
million. In addition, we own interests in unconsolidated entities subject to total indebtedness in the amount of $2.2 billion as of March 31, 2009. Mortgage loans, which comprise a portion of both the consolidated and unconsolidated
indebtedness, are secured by first deeds of trust in the related real property. Mezzanine loans and other secured loans are secured by our direct or indirect ownership interest in the entity that owns the related real property.

We have $17.0 million of consolidated debt which matures in 2009 related to the Campus El Segundo mortgage loan, which we have guaranteed. This loan has
a one-year extension option at our election subject to us complying with certain loan covenants. We were in compliance with these covenants as of March 31, 2009 and expect to be in compliance at the extension date. We expect to exercise our
option to extend this loan. On April 3, 2009, we repaid the remaining $2.0 million of debt maturing in 2009, which was due to our former partner in our Campus El Segundo development. We recognized a gain of $0.5 million on early extinguishment
of debt in the first quarter of 2009.

We have approximately $135.1 million of consolidated debt which matures in 2010. The debt maturing
in 2010 includes approximately $36.1 million in nonrecourse senior and junior mezzanine loans secured by our ownership interest in the real estate entities that own Two Commerce Square which mature in January 2010. We will seek to extend or
refinance this debt at maturity. The Four Points Centre construction loan in the amount of $29.4 million matures in June 2010. This loan has two one-year extension

options at our election subject to certain conditions. The first extension option is subject to completion of the improvements and executed leases
representing at least 75% of the net rentable area, among other things. The second extension option is subject to completion of improvements, executed leases representing at least 90% of the net rentable area, and a minimum debt yield, among other
things. We have guaranteed the completion of construction and have completed the core and shell of this property. Furthermore, we have guaranteed 46.5% of the principal, interest and any other sum payable under this loan; this guaranty is currently
limited to a maximum of $13.3 million. Upon the occurrence of certain events our maximum liability as guarantor will be reduced to 31.5% of all sums payable under this loan, and upon the occurrence of further events our maximum liability as
guarantor will be reduced to 25% of all sums payable under this loan. The Murano construction loan, with a balance of approximately $69.6 million as of March 31, 2009 has a maturity date of July 31, 2009, however it has two six-month
extension options, which are conditional on the closing of 100 residential units, which has occurred, and therefore we expect to exercise these options, and extend the maturity date to July 31, 2010. This loan is nonrecourse to the Company but
the Company guarantees the payment of interest on the loan during the term of the loan as it may be extended. Additionally, the Company has a construction completion guaranty. We amortize the principal balance of the Murano construction loan with
sales proceeds as we close on the sale of condominium units.

We have investments in entities owning unconsolidated properties with stated
ownership percentages ranging from 6.25% to 50.0%. These unconsolidated entities have approximately $814.4 million of debt maturing in 2009, all of which is subject to extension options at our election subject to certain conditions, all of which
extension options the Company intends to exercise. These unconsolidated entities have approximately $1.2 billion of debt maturing in 2010 (including debt extended from 2009 to 2010), approximately $305.2 million of which is subject to extension
options at our election subject to certain conditions.

We may seek to incur significant additional debt to finance future acquisition and
development activities, however debt financing may not be available to us on acceptable terms under current market conditions. In addition, it is possible the required payments of principal and interest on borrowings may leave us with insufficient
cash to operate our properties profitably. Our need for debt financing, our existing level of debt and the limitations imposed on us by our debt agreements could have significant adverse consequences, including the following:



| |  |  | our cash flow may be insufficient to meet our required principal and interest payments or to pay dividends;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to borrow additional funds as needed or on favorable terms;
| | - |  | ----------------------------------------------------------------------------



| |  |  | we may be unable to refinance our indebtedness at maturity or the refinancing terms may be less favorable than the terms of our original indebtedness;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to distribute funds from a property to our Operating Partnership or apply such funds to cover expenses related to another property;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we could be required to dispose of one or more of our properties, possibly on disadvantageous terms and/or at disadvantageous times;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we could default on our obligations and the lenders or mortgagees may foreclose on our properties that secure their loans and receive an assignment of rents and
leases;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we could violate covenants in our loan documents or our joint venture agreements, including provisions that may limit our ability to further mortgage a property,
make distributions, acquire additional properties, repay indebtedness prior to a set date without payment of a premium or other pre-payment penalties, all of which would entitle the lenders to accelerate our debt obligations;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a default under any one of our mortgage loans with cross default provisions could result in a default on other indebtedness; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | because we have agreed to use commercially reasonable efforts to maintain certain debt levels to provide the ability for Mr. Thomas and entities controlled by
him to guarantee debt of $210 million, including $11 million of debt available for guarantee by Mr. Edward Fox, one of our non-employee directors, and by Mr. Richard Gilchrist, an individual formerly affiliated with Maguire Thomas
Partners, we may not be able to refinance our debt when it would otherwise be advantageous to do so or to reduce our indebtedness when our board of directors thinks it is prudent.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If any one of these events were to occur, our revenue and profitability could be adversely impacted, causing a significant downturn in our financial
condition, results of operations, cash flow, and the trading price of our common stock and impairing our ability to satisfy our debt service obligations

We have a substantial amount of debt which bears interest at variable rates. Our failure to hedge effectively against interest rate changes may adversely affect our results of operations.

As of March 31, 2009, $116.0 million of our consolidated debt and $1.1 billion of our unconsolidated debt was at variable interest rates. As of
March 31, 2009, interest rate caps have been purchased for $1.05 billion of the unconsolidated floating rate loans. Interest rate hedging arrangements and swap agreements we enter into to cap our interest rate exposure involve risks, including
that our hedging or swap transactions might not achieve the desired effect in eliminating the impact of interest rate fluctuations, or that

##### Table of Contents

counterparties may fail to honor their obligations under these arrangements. As a result, these arrangements may not be effective in reducing our exposure to
interest rate fluctuations and this could reduce our revenue, require us to modify our leverage strategy, and adversely affect our expected investment returns. Of the existing interest rate caps, one or more Lehman Brothers Holdings, Inc. affiliates
was the counterparty on the interest rate cap transactions related to our Austin Portfolio Joint Venture Properties. We have replaced the Lehman affiliates as counterparty on four interest rate cap transactions at a cost of $60,000. The last
remaining hedging arrangement in which a Lehman affiliate is a counterparty is an interest rate collar agreement for 50% of the original loan balance of the Term Loan, or $96.25 million, in which we bought a cap and sold a floor. During the fourth
quarter of 2008, the Lehman affiliate stopped accepting payment on this rate collar. We have accrued the obligation due if the Lehman affiliate were accepting payment. We are discussing a resolution of this matter with the Lehman affiliate.

We may be unable to complete acquisitions necessary to grow our business, and even if consummated, we may fail to successfully operate these acquired
properties.

Our planned growth strategy includes the acquisition of additional properties as opportunities arise. We regularly evaluate
approximately 20 markets in the United States for office, mixed-use and other properties for strategic opportunities. Our ability to acquire properties on favorable terms and successfully operate them is subject to the following significant
risks:



| |  |  | we may be unable to generate sufficient cash from operations, or obtain the necessary debt or equity to consummate an acquisition or, if obtainable, it may not be
on favorable terms;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may need to spend more than budgeted amounts to make necessary improvements or renovations to acquired properties;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to acquire a desired property because of competition from other real estate investors with more available capital, including other real estate
operating companies, real estate investment trusts and investment funds;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | competition from other potential acquirers may significantly increase the purchase price, even if we are able to acquire a desired property;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | agreements for the acquisition of office properties are typically subject to customary conditions to closing, including satisfactory completion of due diligence
investigations, and we may spend significant time and money on a potential acquisition we eventually decide not to pursue;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | market conditions may result in higher than expected vacancy rates and lower than expected rental rates; and
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | we may acquire properties subject to liabilities without any recourse, or with only limited recourse, for unknown liabilities such as clean-up of undisclosed
environmental contamination, claims by tenants, vendors or other persons dealing with the former owners of the properties and claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the
properties.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If we cannot complete property acquisitions on favorable terms, or operate acquired properties to meet our
expectations, our revenue and profitability could be adversely impacted, causing a significant downturn in our financial condition, results of operations, trading price of our common stock, and impairing our ability to satisfy our debt service
obligations.

Our real estate acquisitions may result in disruptions to our business as a result of the burden in integrating operations placed on our
management.

Our business strategy includes acquisitions and investments in real estate on an ongoing basis. These acquisitions may
cause disruptions in our operations and divert managements attention from day-to-day operations, which could impair our relationships with our current tenants and employees. In addition, if we acquire real estate by acquiring another entity,
we may be unable to effectively integrate the operations and personnel of the acquired business. In addition, we may be unable to train, retain and motivate any key personnel from the acquired business. If our management is unable to effectively
implement our acquisition strategy, we may experience disruptions to our business.

We may be unable to successfully complete and operate properties
under development, which would impair our financial condition and operating results.

A significant part of our business is devoted to
the development of office, mixed-use and other properties, including the redevelopment of core plus and value-add properties. Our development, construction and redevelopment activities involve the following significant risks:



| |  |  | we may be unable to obtain construction or redevelopment financing on favorable terms or at all;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | if we finance development projects through construction loans, we may be unable to obtain permanent financing at all or on advantageous terms;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may not complete development projects on schedule or within budgeted amounts;
| | - |  | --------------------------------------------------------------------------------

##### Table of Contents

| |  |  | we may underestimate the expected costs and time necessary to achieve the desired result with a redevelopment project;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | we may discover structural, environmental or other feasibility issues with properties acquired as redevelopment projects following our acquisition, which may render
the redevelopment as planned not possible;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may encounter delays or refusals in obtaining all necessary zoning, land use, building, occupancy, and other required governmental permits and authorizations;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | occupancy rates and rents at newly developed or renovated properties may fluctuate depending on a number of factors, including market and economic conditions, and
may result in our investment not being profitable;

| |  |  | adverse weather that damages the project or causes delays;
| | - |  | ----------------------------------------------------------



| |  |  | changes to the plans or specifications;

| |  |  | shortages of qualified employees;
| | - |  | ---------------------------------



| |  |  | fire, flooding and other natural disasters; and
| | - |  | -----------------------------------------------



| |  |  | inability to sell or close on the sale of condominium units at Murano.
| | - |  | ----------------------------------------------------------------------

If we are not successful in our property development initiatives, it could adversely impact our revenue and profitability, causing a significant downturn
in our business, including our financial condition, results of operations, trading price of our common stock and impairing our ability to satisfy our debt service obligations. Additionally, since 2007 the residential housing market has experienced a
decline and we could experience difficulties in selling or closing on the sale of condominium units at Murano.

We face significant competition, which
may decrease or prevent increases of the occupancy and rental rates of our properties.

We face significant competition from other
developers, managers and owners of office and mixed-use real estate, many of which own properties similar to ours in the same regional markets in which our properties are located. We also compete with other diversified real estate companies and
companies focused solely on offering property investment management and brokerage services. A number of our competitors are larger and better able to take advantage of efficiencies created by size, and have better financial resources, or increased
access to capital at lower costs, and may be better known in regional markets in which we compete. Our smaller size as compared to some of our competition may increase our susceptibility to economic downturns and pressures on rents. Our failure to
compete successfully in our industry would materially affect our business prospects.

We may be unable to renew leases, lease vacant space or re-lease
space as leases expire resulting in increased vacancy rates, lower revenue and an adverse effect on our operating results.

As of
March 31, 2009, leases representing 4.7% and 7.6% of the rentable square feet of the office and mixed-use properties in which we hold an ownership interest will expire in 2009 and 2010, respectively. Further, an additional 15.2% of the square
feet of these properties was available for lease as of March 31, 2009. Rental rates on existing leases above the current market rate at some of the properties in our office and mixed-use portfolio may require us to renew or re-lease some
expiring leases at lower rates. If the rental rates for our properties decrease, our existing tenants do not renew their leases or we do not re-lease a significant portion of our available space and space for which leases will expire, our revenue
and profitability could be adversely impacted, causing a significant downturn in our financial condition, results of operations, cash flow, and the trading price of our common stock and impairing our ability to satisfy our debt service obligations.
Current economic and real estate market conditions have resulted in depressed leasing activity recently as a result of tenant unwillingness to make long term leasing commitments given recent financial markets upheaval, and it is unclear how long
this may continue to prevail.

A significant amount of space at our Two Commerce Square property has historically been leased to Conrail.
Approximately half or 375,000 square feet of this lease expired in June 2008 and the remaining half expires in June 2009. Conrail currently subleases substantially all of its space to a number of subtenants. While we have entered into agreements
with many of the subtenants for direct leases once their sublease term expires, the rental rates are lower than paid by the current tenant. As a result, we currently expect our aggregate revenues from this property will be lower following the
expiration of the Conrail lease in 2009. We have entered into direct leases for all of the 378,000 square feet of Conrail space expiring in 2009. The lease terms range from 5 months to 78 months. If we are unable to lease the remaining 129,000
square feet of the space leased by Conrail in Two Commerce Square until June 2008, our rental revenue (excluding tenant reimbursements revenue) computed in accordance with United States generally accepted accounting principles (GAAP)
would decrease by $1.6 million in 2009 as compared to 2008, and $2.3 million in 2010 as compared to 2009.

Our growth depends on external sources of capital, some of which are outside of our control. If we are unable to
access capital from external sources, we may not be able to implement our business strategy.

Our business strategy requires us to rely
significantly on third-party sources to fund our capital needs. We may not be able to obtain debt or equity on favorable terms or at all. Since the second half of 2007 we have experienced an increasing tightening of the credit markets, and we may
experience difficulty refinancing existing debt or obtaining new debt to complete acquisitions. Any additional debt we incur will increase our leverage. Any issuance of equity by our company will cause dilution to our existing stockholders, and
could have a negative impact on our stock price. Our access to third-party sources of capital depends, in part, on:



| |  |  | our current debt levels, which were $392.5 million of consolidated debt and $2.2 billion of unconsolidated debt as of March 31, 2009;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our current cash flow from operating activities, which resulted in a use of cash of $12.0 million for the three months ended March 31, 2009;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our current and expected future earnings;
| | - |  | -----------------------------------------



| |  |  | the markets perception of our growth potential;
| | - |  | ------------------------------------------------



| |  |  | the market price per share of our common stock;
| | - |  | -----------------------------------------------



| |  |  | the perception of the value of an investment in our common stock; and
| | - |  | ---------------------------------------------------------------------



| |  |  | general market conditions.
| | - |  | --------------------------

If we
cannot obtain capital from third-party sources, we may not be able to acquire or develop properties when strategic opportunities exist, satisfy our debt service obligations or continue to fund operations.

As a result of the limited time during which we have to perform due diligence of many of our acquired properties, we may become subject to significant unexpected
liabilities and our properties may not meet projections.

When we enter into an agreement to acquire a property or portfolio of
properties, we often have limited time to complete our due diligence prior to acquiring the property. To the extent we underestimate or fail to investigate or identify risks and liabilities associated with the properties we acquire, we may incur
unexpected liabilities or the property may fail to perform as we expected. If we do not accurately assess the liabilities associated with properties prior to their acquisition, we may pay a purchase price that exceeds the current fair value of the
net identifiable assets of the acquired property. As a result, intangible assets would be required to be recorded, which could result in significant accounting charges in future periods. These charges, in addition to the financial impact of
significant liabilities that we may assume, could adversely impact our revenue and profitability, causing a significant downturn in our financial condition, results of operations, trading price of our common stock and impairing our ability to
satisfy our debt service obligations.

Our efforts to expand our geographic presence and diversify into other regional real estate markets may not be
successful, thereby constraining our growth to markets in which we currently operate.

We intend to expand our business to new
geographic regions where we expect the development, ownership and management of property to result in favorable risk-adjusted investment returns. In order for us to achieve economies of scale, we generally target ownership of 500,000 or more
rentable square feet in a market. It may be difficult for us to achieve this level of ownership and our initial entry into a particular market may result in higher administrative expenses for us initially. Presently, we do not possess the same level
of familiarity with the development, ownership and management of properties in locations other than the West Coast, Southwest and Mid-Atlantic regions in the United States, which could adversely affect our ability to develop properties outside these
regions successfully or at all or to achieve expected performance.

We could incur significant costs related to government regulation and private
litigation over environmental matters, including with respect to clean-up of contaminated properties and litigation from any harm caused by environmental hazards on our properties.

Under various federal, state and local environmental laws and regulations, a current or previous owner, manager or tenant of real estate may be required
to investigate and clean up hazardous or toxic substances at the property, and may be held liable to a government entity or to third parties for property damage and for investigation, clean-up and monitoring costs incurred by the parties in
connection with the actual or threatened contamination. These laws typically impose clean-up responsibility and liability without regard to fault, or whether or not the owner, operator or tenant knew of or caused the presence of the contamination.
The liability under the laws may be joint and several for the full amount of the investigation, clean-up and monitoring costs incurred or to be incurred or actions to be undertaken, although a party held jointly and severally liable may obtain
contributions from other identified, solvent, responsible parties of their fair share toward these costs to the extent such contributions are possible to obtain. These costs may be substantial, and may exceed the value of the property. The presence
of contamination, or the failure to properly remediate contamination on a property may limit the ability of the owner, operator or tenant to sell or rent that property or to borrow using the property as collateral, and may cause our investment in
that property to decline in value.

Federal regulations require building owners and those exercising control over a buildings
management to identify and warn of, by signs and labels, potential hazards posed by workplace exposure to installed asbestos-containing materials and potentially

asbestos- containing materials in their building. The regulations also set forth employee training, record keeping and due diligence requirements pertaining
to asbestos-containing materials and potentially asbestos-containing materials. Significant fines can be assessed for violation of these regulations. Building owners and managers may be subject to an increased risk of personal injury lawsuits by
workers and others exposed to asbestos-containing materials and potentially asbestos-containing materials as a result of these regulations. The regulations may affect the value of a building incorporating asbestos-containing materials or potentially
asbestos-containing materials that we own or manage.

We are aware of potentially environmentally hazardous or toxic materials at three of
our properties in which we hold an ownership interest. Prior to commencing construction at our Murano development property, we engaged in remediation efforts as a result of a gasoline spill that occurred on the premises in April 2002, due to an
accident caused by the former tenants agent. All soil remediation work has been completed. We are operating under a regulatory requirement to monitor the ground water to achieve four consecutive quarters of acceptable sample results.

With respect to asbestos-containing materials present at our City National Plaza and Brookhollow properties, these materials have been
removed or abated from certain tenant and common areas of the building structures. We continue to remove or abate asbestos-containing materials from various areas of the building structures and as of March 31, 2009, have accrued $0.9 million
for estimated future costs of such removal or abatement at City National Plaza.

Federal, state and local laws and regulations also govern
the removal, encapsulation, disturbance, handling and/or disposal of asbestos-containing materials and potentially asbestos-containing materials. These laws may impose liability for improper handling or a release to the environment of
asbestos-containing materials and potentially asbestos-containing materials. In addition, fines may be imposed on owners or managers of real properties for personal injury or improper work exposure associated with asbestos-containing materials and
potentially asbestos-containing materials.

Tax indemnification obligations that may arise in the event we or our Operating Partnership sell an interest
in either of two of our properties could limit our operating flexibility.

We and our Operating Partnership have agreed to indemnify
Mr. Thomas against adverse direct and indirect tax consequences in the event that our Operating Partnership or the underlying property joint venture directly or indirectly sells, exchanges or otherwise disposes (including by way of merger, sale
of assets or otherwise) of any portion of its interests, in a taxable transaction, in either One Commerce Square or Two Commerce Square. These two properties represented 13.7% of annualized rent for properties in which we hold an ownership interest
as of March 31, 2009. The indemnification currently expires October 13, 2013, which may be further extended to October 13, 2016 provided Mr. Thomas and his controlled entities collectively retain at least 50% of the Operating
Partnership units received by them in connection with our formation transactions at the time of our initial public offering.

We have also
agreed to use commercially reasonable efforts to make approximately $210 million of debt available to be guaranteed by entities controlled by Mr. Thomas, by Mr. Fox, a non-employee member of our board of directors, and by
Mr. Gilchrist, an individual formerly affiliated with Maguire Thomas Partners. We agreed to make this debt available for guarantee in order to assist Mr. Thomas and these other persons in preserving their tax position after their
contributions at the time of our initial public offering.

Risks Related to the Real Estate Industry

The current economic environment for real estate companies and credit crisis may significantly adversely impact our results of operations and business prospects.

The success of our business and profitability of our operations are dependent on continued investment in the real estate markets and access
to capital and debt financing. A long term crisis of confidence in real estate investing and lack of available credit for acquisitions would be likely to constrain our business growth. As part of our business goals, we intend to grow our properties
portfolio with strategic acquisitions of core properties at advantageous prices, and core plus and value added properties where we believe we can bring necessary expertise to bear to increase property values. In order to pursue acquisitions, we need
access to equity capital and also property-level debt financing. Current disruptions in the financial markets, including the bankruptcy and restructuring of major financial institutions, may adversely impact our ability to refinance existing debt
and the availability and cost of credit in the near future. Presently, access to capital and debt financing options are severely restricted and it is uncertain how long current economic circumstances may last. Any consideration of sales of existing
properties or portfolio interests may be tempered by the depressed nature of property values at present. Our ability to make scheduled payments or to refinance our obligations with respect to indebtedness depends on our operating and financial
performance, which in turn is subject to prevailing economic conditions. There can be no assurances that government responses to the disruptions in the financial markets will restore investor confidence, stabilize the markets or increase liquidity
and the availability of credit.

Illiquidity of real estate investments and the susceptibility of the real estate industry to economic conditions could
significantly impede our ability to respond to adverse changes in the performance of our properties.

Our ability to achieve desired and
projected results for growth of our business depends on our ability to generate revenues in excess of expenses, and make scheduled principal payments on debt and fund capital expenditure requirements. Events and conditions generally applicable to
owners and operators of real property that are beyond our control may adversely impact results of operations and the value of our properties. These events include:



| |  |  | vacancies or our inability to rent space on favorable terms;
| | - |  | ------------------------------------------------------------



| |  |  | inability to collect rent from tenants;
| | - |  | ---------------------------------------



| |  |  | difficulty in accessing credit in the present economic environment, in particular for larger mortgage loans;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | inability to finance property development and acquisitions on favorable terms;
| | - |  | ------------------------------------------------------------------------------



| |  |  | increased operating costs, including real estate taxes, insurance premiums and utilities;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | local oversupply, increased competition or reduction in demand for office space;
| | - |  | --------------------------------------------------------------------------------



| |  |  | costs of complying with changes in governmental regulations;
| | - |  | ------------------------------------------------------------



| |  |  | the relative illiquidity of real estate investments;
| | - |  | ----------------------------------------------------



| |  |  | changing submarket demographics; and
| | - |  | ------------------------------------



| |  |  | the significant transaction costs related to property sales, including a high transfer tax rate in the City of Philadelphia.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------

In addition, periods of economic slowdown or recession, rising interest rates or declining demand for real estate, or the public perception that any of
these events may occur, could result in a general decline in rents or an increased incidence of defaults under existing leases. If any of these events were to happen, our revenue and profitability could be impaired, causing a significant downturn in
our financial condition, results of operations, cash flow, and trading price of our common stock and our ability to satisfy our debt service obligations could be impaired.

Compliance with the Americans with Disabilities Act and fire, safety and other regulations may require us to make unintended expenditures that adversely impact our financial condition.

All of our commercial properties are required to comply with the Americans with Disabilities Act, or ADA. The ADA has separate compliance requirements for
public accommodations and commercial facilities, but generally requires that buildings be made accessible to people with disabilities. The obligation to make readily achievable accommodations is an ongoing one, and we assess
our properties and make alterations as appropriate. Compliance with the ADA requirements could require removal of access barriers. Non-compliance could result in imposition of fines by the U.S. government or an award of damages to private litigants,
or both. Typically, we are responsible for changes to a building structure that are required by the ADA, which can be costly. In addition, we are required to operate our properties in compliance with fire and safety regulations, building codes and
other land use regulations. We may be required to make substantial capital expenditures to comply with these requirements thereby limiting the funds available to operate, develop and redevelop our properties and acquire additional properties. As a
result, these expenditures could negatively impact our revenue and profitability.

Potential losses may not be covered by insurance and may result in
our inability to repair damaged properties and we could lose invested capital.

We carry comprehensive liability, fire, flood, extended
coverage, wind, earthquake, terrorism, pollution legal liability, business interruption and rental loss insurance under our blanket policy covering all of the properties which we own an interest in or manage for third parties, including our
development properties (although we carry only liability insurance for the CalEPA headquarters building under our blanket policy because the tenant has the right to provide all other forms of coverage it deems necessary, and it has elected to do
so). We believe the policy specifications and insured limits are appropriate and adequate given the relative risk of loss, the cost of the coverage and industry practice. We carry earthquake insurance on our properties located in seismically active
areas, which includes our Southern California properties, wind insurance on our properties located in tier 1 wind zones, which includes our Houston, Texas properties, and terrorism insurance on all of our properties. Our terrorism
insurance is subject to exclusions for loss or damage caused by nuclear substances, pollutants, contaminants, and biological and chemical weapons as more specifically excluded under the actual terrorism policies. Some of our policies, like those
covering losses due to earthquakes and terrorism, are subject to limitations involving deductibles and policy limits which may not be sufficient to cover losses. We either own or have interests in a number of properties in Southern California, an
area especially prone to earthquakes.

Under their leases, tenants are generally required to indemnify us from liabilities resulting from
injury to persons, air, water, land or property, on or off the premises due to activities conducted by them on our properties. There is an exception for claims arising from the negligence or intentional misconduct by us or our agents. Additionally,
tenants are generally required, with the exception of governmental entities and other entities that are self-insured, to obtain and keep in force during the term of the lease liability and property damage insurance policies issued by companies
holding ratings at a minimum level at their own expense.

Although we have not experienced such a loss to date, if we experience a loss
that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged property as well as the anticipated future cash flows from that property, including lost

revenue from unpaid rent from tenants. In addition, if the damaged property is subject to recourse indebtedness, we would continue to be liable for the
indebtedness, even if this property was irreparably damaged. In the event of a significant loss at one or more of the properties covered by the blanket policy, the remaining insurance under our policy, if any, could be insufficient to adequately
insure our remaining properties. In this event, securing additional insurance, if possible, could be significantly more expensive than our current policy.

Risks Related to Our Organization and Structure

Our senior management has existing conflicts of interest with us and our public
stockholders that could result in decisions adverse to our company.

As of March 31, 2009, Mr. Thomas owns or controls a
significant interest in our Operating Partnership consisting of 13,813,331 units, or a 35.0% interest (including units beneficially owned by other senior executive officers) as of such date. In addition, our senior executive officers, excluding
Mr. Thomas, collectively hold an interest in Operating Partnership units, incentive units (vested and unvested) and common stock aggregating a 6.0% interest in our company.

The various terms of these equity and incentive interests could create conflicts of interest with our public stockholders. Members of executive
management could be required to make decisions that could have different implications for our Operating Partnership and for us, including:



| |  |  | potential acquisitions or sales of properties;
| | - |  | ----------------------------------------------



| |  |  | the issuance or disposition of shares of our common stock or units in our Operating Partnership; and
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the payment of dividends by us.
| | - |  | -------------------------------

For
example, an acquisition in exchange for the issuance by our Operating Partnership of additional Operating Partnership units would dilute the interests of members of our management team as limited partners in our Operating Partnership. Dispositions
could trigger our tax indemnification obligations with respect to Mr. Thomas. Dividends paid by us to our public stockholders decrease our funds available to reinvest in our business.

We have a holding company structure and rely upon funds received from our Operating Partnership to pay liabilities.

We are a holding company. Our primary asset is our general partnership interest in our Operating Partnership. We have no independent means of generating
revenues. To the extent we require funds to pay taxes or other liabilities incurred by us, to pay dividends or for any other purpose, we must rely on funds received from our Operating Partnership. If our Operating Partnership should become unable to
distribute funds to us, we would be unable to continue operations after a short period. Most of the properties owned by our subsidiaries and joint ventures are encumbered by loans that restrict the distribution of funds to our Operating Partnership.
The loans generally contain lockbox arrangements, reserve requirements, financial covenants and other restrictions and provisions that prior to an event of default may prevent the distribution of funds from the subsidiaries who own these properties
to our Operating Partnership. In the event of a default under these loans, the defaulting subsidiary or joint venture would be prohibited from distributing cash to our Operating Partnership. As a result, our Operating Partnership may be unable to
distribute funds to us and we may be unable to use funds from one property to support the operation of another property. As we acquire new properties and refinance our existing properties, we may finance these properties with new loans that contain
similar provisions. Some of the loans to our subsidiaries and joint ventures may contain provisions that restrict us from loaning funds to our subsidiaries or joint ventures. If we are permitted to loan funds to our subsidiaries or joint ventures,
our loans generally will be subordinated to the existing debt on our properties.

Mr. Thomas has a significant vote in certain matters as a result
of his control of 100% of our limited voting stock.

Each entity that received Operating Partnership units in our formation transactions
received shares of our limited voting stock that are paired with units in our Operating Partnership on a one-for-one basis. All of these entities are directly or indirectly controlled by Mr. Thomas, and, as a result, Mr. Thomas controls
100% of our outstanding limited voting stock, or 38.7% of our outstanding voting stock (including outstanding shares of common stock owned by Mr. Thomas and his affiliates) as of March 31, 2009. These limited voting shares are entitled to
vote in the election of directors, for the approval of certain extraordinary transactions including any merger or sale of the company, amendments to our certificate of incorporation and any other matter required to be submitted to a separate class
vote under Delaware law. Mr. Thomas may have interests that differ from that of our public stockholders, including by reason of his interests held in Operating Partnership units, and may accordingly vote as a stockholder in ways that may not be
consistent with the interests of our public stockholders. This significant voting influence over certain matters may have the effect of delaying, preventing or deterring a change of control of our company, or could deprive our stockholders of an
opportunity to receive a premium for their common stock as part of a sale of our company.

Our success depends on key personnel, the loss of whom could impair our ability to operate our business successfully.

We depend on the efforts of key personnel, particularly Mr. Thomas, our Chairman, Chief Executive Officer, and President. Among
the reasons that Mr. Thomas is important to our success is that he has an industry reputation developed over more than 30 years in the real estate industry that attracts business and investment opportunities and assists us in negotiations with
lenders, existing and potential tenants and industry personnel. If we lost his services, our relationships with these parties could diminish. Mr. Thomas is 72 and, although he has informed us that he does not currently plan to retire, we cannot
be certain how long he will continue working on a full-time basis.

Many of our other senior executives also have significant real estate
industry experience. Mr. Scott has extensive development and management experience on several large-scale projects, including the development, construction and management of One Commerce Square and Two Commerce Square. Mr. Sischo and
Mr. Scott are jointly responsible for oversight of our relationship with CalSTRS. Mr. Sischo is responsible for our acquisition efforts. Mr. Ricci has been extensively involved in the development of large, mixed-use and commercial
projects. Ms. Laing has served as chief financial officer of two publicly-traded real estate investment trusts. Mr. Rutter has extensive experience, both as a real estate lawyer and as an executive in commercial real estate, including
acquisitions, financing, joint ventures and leasing of office and mixed use projects. While we believe that we could find acceptable replacements for these executives, the loss of their services could materially and adversely affect our operations
because of diminished relationships with lenders, existing and prospective tenants and industry personnel. A departure of either Mr. Thomas or Mr. Sischo could also have adverse effects on our joint venture relationship with CalSTRS,
including the possible sale of our joint venture interest to CalSTRS at 97% of fair value, unless within 180 days the Company names a replacement for such departed executive who is reasonably acceptable to CalSTRS.

Some provisions of our certificate of incorporation and bylaws may deter takeover attempts, which may limit the opportunity of our stockholders to sell their shares
at a favorable price.

Some of the provisions of our certificate of incorporation and bylaws could make it more difficult for a third
party to acquire us, even if doing so might be beneficial to our stockholders by providing them with the opportunity to possibly sell their shares at a premium over the then market price. Our certificate of incorporation and bylaws contain
provisions including the following:



| |  |  | vacancies on our board of directors may only be filled by the remaining directors;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | only the board of directors can change the number of directors;
| | - |  | ---------------------------------------------------------------



| |  |  | there is no provision for cumulative voting for directors;
| | - |  | ----------------------------------------------------------



| |  |  | directors may only be removed for cause; and
| | - |  | --------------------------------------------



| |  |  | our stockholders are not permitted to act by written consent.
| | - |  | -------------------------------------------------------------

In addition, our certificate of incorporation authorizes the board of directors to issue up to 25,000,000 shares of preferred stock. The preferred stock may be issued in one or more series, the terms of which will be
determined at the time of issuance by our board of directors without further action by the stockholders. These terms may include voting rights, including the right to vote as a series on particular matters, preferences as to dividends and
liquidation, conversion rights, redemption rights and sinking fund provisions. The issuance of any preferred stock could diminish the rights of holders of our common stock, and therefore could reduce the value of our common stock. In addition,
specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell assets to, a third party. The ability of our board of directors to issue preferred stock could make it more difficult, delay,
discourage, prevent or make it more costly to acquire or effect a change in control, thereby preserving the current stockholders control of our company.

Finally, we are also subject to Section 203 of the Delaware General Corporation Law which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that the stockholder became an interested stockholder.

The
provisions of our certificate of incorporation and bylaws, described above, as well as Section 203 of the Delaware General Corporation Law, could discourage potential acquisition proposals, delay or prevent a change of control and prevent
changes in our management, even if these events would be in the best interests of our stockholders.

We could authorize and issue stock without
stockholder approval, which could cause our stock price to decline and dilute the holdings of our existing stockholders.

Our
certificate of incorporation authorizes our board of directors to issue authorized but unissued shares of our common stock or preferred stock and to classify or reclassify any unissued shares of our common stock or preferred stock and to set the
preferences, rights and other terms of the classified or unclassified shares. Although our board of directors has no intention at the present time, it could establish a series of preferred stock that could, depending on the terms of the series,
delay, defer or prevent a transaction or a change of control that might involve a premium price for our common stock or otherwise be in the best interest of our stockholders.
