1. Organization and Description of Business

The terms Thomas Properties, 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., or the Operating Partnership.

We were incorporated in the State of Delaware on March 9, 2004 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, as well as mixed-use and residential, located in Southern California; Sacramento, California; Philadelphia, Pennsylvania; Northern Virginia; Houston, Texas; and Austin, Texas. The ultimate owners of TPGI Predecessor were
Mr. James A. Thomas, our Chairman, Chief Executive Officer and President, and certain others who had minor ownership interests.

Our business 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 and the assumption of debt and
other specified liabilities in exchange for limited partnership units (Units) in the Operating Partnership issued to the contributors. As of June 30, 2007, we held a 60.5% interest in the Operating Partnership which we consolidated,
as we have control over the major decisions of the Operating Partnership.

As of June 30, 2007, we were invested in the following real
estate entities:

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 owned by Mr. Thomas and entities majority owned by him were contributed to the Operating
Partnership in exchange for Units and 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. 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.

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 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 One Commerce Square and Two Commerce Square (for all periods presented) and Murano (beginning August 2, 2006) not
owned by us are reflected as minority interests. Mr. Thomas has an 11% ownership interest in each of One Commerce Square and Two Commerce Square. No further losses of One Commerce Square and Two Commerce Square are being allocated to
Mr. Thomas, as no further contributions are required from Mr. Thomas. Future income allocable to Mr. Thomas will be reduced by such unrecognized losses. The unrecognized minority interest of Mr. Thomas in the deficit of One
Commerce Square and Two Commerce Square is $1.5 million and $1.4 million at June 30, 2007 and December 31, 2006, respectively.

We have a $20,510,000 preferred equity interest in Murano, of which we have fully funded the required cash commitment of $17,422,000 as of June 30, 2007. Excluding the preferred equity interest, a third party has a 27.0% ownership
interest in Murano.

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 unvested 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 $11,294,000 and $8,109,000 as of June 30, 2007 and December 31, 2006, respectively.

Gains on Dispositions of Real Estate

Gains on sales
of real estate are recognized pursuant to the provisions of Financial Accounting Standard Board (FASB) Statement No. 66, Accounting for Sales of Real Estate (SFAS 66). The specific timing of a sale is measured against various
criteria in SFAS 66 related to the terms of the transaction and any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for
the continued operations of the property by applying the deposit, finance, installment, percentage of completion or cost recovery methods, as appropriate.

Recent Accounting Pronouncements

In July 2006, FASB issued FASB Interpretation No. 48 (FIN 48), Accounting for
Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109, Accounting for Income Taxes, which is effective for fiscal years beginning after December 15, 2006, and clarifies the accounting for uncertainty in tax
positions. FIN 48 requires that we recognize the impact of a tax position in our financial statements if that position would more likely than not be sustained on audit, based on the technical merits of the position. See note 7 for further details
regarding the adoption of FIN 48.

In September 2006, FASB issued FASB Statement No. 157 (SFAS 157), Fair Value
Measurement, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and provides for expanded disclosure about fair value measurements. This statement applies under other
accounting pronouncements that require or permit fair value measurements. This guidance was issued to increase consistency and comparability in fair value measurements and to expand disclosures about fair value measurements. This statement is
effective for financial statements issued for fiscal years beginning after November 15, 2007. We do not expect that the adoption of SFAS 157 will have a material impact on our financial statements.

In September 2006, the Emerging Issues Task Force (EITF) of the FASB issued EITF Issue No. 06-8, Applicability of the Assessment of a Buyers
Continuing Investment under SFAS No. 66 for the Sale of Condominiums (EITF 06-8). EITF 06-8 states that in assessing the collectibility of the sales price pursuant to SFAS 66, an entity should evaluate the adequacy of the buyers initial
and continuing investment to conclude that the sales price is collectible. If an entity is unable to meet the criteria of SFAS 66, including an assessment of collectibility using the initial and continuing investment tests described in SFAS 66, then
the entity should apply the deposit method as described in SFAS 66. In November 2006, the FASB ratified the EITFs recommendation. This statement is effective for financial statements issued for fiscal years beginning after March 15, 2007. The
Company is currently applying the deposit method, and will continue to evaluate this method versus the percentage of completion method in future periods.

In February 2007, the FASB issued FASB Statement No. 159 (SFAS No. 159), The Fair Value Option for Financial Assets and Financial Liabilities. SFAS No. 159 permits all entities to choose to measure
eligible items at fair value at specified election dates. SFAS 159 is effective as of the beginning of an entitys first fiscal year that begins after November 15, 2007. The Company is evaluating SFAS No. 159 and has not yet determined the
impact the adoption will have on the Companys financial position or results of operations.

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 (SEC). Accordingly, they do not include all of the disclosures required by GAAP for complete
financial statements and should be read in conjunction with the financial statements and notes thereto included in our Annual Report for the year ended December 31, 2006 filed with the SEC on Form 10-K as amended by Amendment No. 1. 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.

Capital contributions, distributions, and profits and losses of the real estate entities are allocated in accordance with the terms of the applicable partnership and limited liability company agreements. Such allocations may differ from the
stated ownership percentage interests in such entities as a result of preferred returns and allocation formulas as described in the partnership and limited liability company agreements.Our stated ownership percentages, prior to any preferred or
special allocations, as of June 30, 2007, follow:



|                            |  |      |     
|--------------------------- |  | ---- | ----
|2121 Market Street          |  | 50.0 | %   
|Harris Building Associates  |  | 0.1  | %(1)

|(1) | The partnership that owns 2121 Market Street entered into a master lease for the property with Harris Building Associates designed to allow a third party investor to take advantage
of the historic tax credits for the property. The Operating Partnership and an unrelated party each hold a 0.05% general partnership interest in Harris Building Associates. The 99.9% limited partner of Harris Building Associates contributed $3.5
million and no further contributions are required. In addition, this partner is entitled to various distributions, fees, and priority returns. During 2004, the accumulated losses and distributions for this limited partner equaled their contribution
amount and priority return. As such, net income/loss is allocated equally to the general partners, resulting in an allocation of 50% net income/loss to us.

|(2) | Prior to January 1, 2006, the minority owner of City National Plaza and the Operating Partnership were allocated depreciation expense of City National Plaza ahead of CalSTRS,
resulting in the allocation to us of 22.5% of City National Plazas depreciation expense and 21.3% of City National Plazas net income/loss (excluding depreciation expense). During 2005, the accumulated losses and distributions for the
minority owner equaled their contribution amount. As such, net income/loss is allocated to the Operating Partnership and CalSTRS.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Beginning January 1, 2006, the Operating Partnership is allocated 25% of net income/loss, including depreciation expense. Depreciation expense was previously allocated to the members in accordance with the operating agreement of the
limited liability company. The minority owner and the Operating Partnership were initially allocated depreciation expense ahead of CalSTRS. Based on the American Institute of Certified Public Accountants (AICPA) Statement of Position
78-9 Accounting for Investments in Real Estate Ventures, we determined that the allocation of net income/loss, including depreciation expense, to the members should be based on the allocation of cash distributions and liquidating
distributions, not the profit and loss allocation ratios as specified in the operating agreement.

##### Table of Contents

TPG/CalSTRS, LLC, 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 stabilized 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.

The total initial capital commitment to the joint venture was $333.3 million, which was fully
funded as of December 31, 2006. Our aggregate commitment to the joint venture was $83.3 million and CalSTRS aggregate commitment was $250.0 million. On June 8, 2006, we amended our agreement with CalSTRS to allow for all
capital distributions to be recalled as additional capital contributions through May 1, 2007. On May 25, 2007, we revised our agreement with CalSTRS, which amended the investment period to end on the earlier of (a) the date CalSTRS
has made aggregate capital contributions at least equal to $265.0 million; or (b) June 1, 2007. We are in the process of finalizing a further amendment with CalSTRS to provide for additional capital commitments in the amounts of $135.0
million and $45.0 million from CalSTRS and us, respectively.

A buy-sell provision may be exercised under the joint venture agreement 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 either elect to 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 minority
owners of City National Plaza have the option to require the joint venture to purchase its interest for an amount equal to what would be payable to them upon liquidation of the assets at fair market value.

Following is summarized financial information for the unconsolidated real estate entities as of June 30, 2007 and December 31, 2006 and for the
three and six months ended June 30, 2007 and 2006 (in thousands):

6. Stockholders Equity

On April 25, 2007, we sold 9,200,000 shares of common stock, pursuant to an effective registration statement previously filed with the Securities and Exchange Commission, at $16.00 per share. We received net proceeds, after deducting
underwriting discounts and commissions and offering expenses, of $139.3 million from this offering of which $33.7 million was used to redeem 2,170,000 units in our operating partnership held by our Chief Executive Officer and President, and 45,000
units held by another senior executive.

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 for cash, or exchanged for shares of common stock at our election, on a one-for-one basis. We have issued 1,033,339 incentive units
to certain employees, of which 45,000 was redeemed for cash in April 2007. 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 23,747,936 shares of common stock, and 14,496,666 Units outstanding as of June 30, 2007, and
988,336 incentive units outstanding which were issued under our Incentive Plan, defined below.

We adopted the 2004 Equity Incentive Plan
of Thomas Properties Group, Inc. (the Incentive Plan) effective upon the closing of our initial public offering. 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. At the Annual Meeting of shareholders in May 2007, the
shareholders approved an increase in the number of shares of the common stock reserved for issuance or transfer under the Plan from 2,011,906 shares to a total of 2,361,906. In addition, the restrictions on the aggregate number of shares that may be
issued or transferred with respect to specified awards granted under the Plan were eliminated. In addition, under our Non-Employee Directors Restricted Stock Plan (the Non-Employee Directors Plan) a total of 60,000 shares were reserved
for grant at the time of our original public offering, of which 35,033 shares remain available for future grant at June 30, 2007.

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:

The 10,000 and 4,984 shares vested following the 2006 Annual Meeting of Stockholders on
May 24, 2006. Vesting for the 6,419 and 3,564 shares commenced as of May 24, 2006 and May 30, 2007, respectively. Of the 6,419 shares granted, 3,501 vested following the 2007 Annual Meeting of Stockholders on May 30, 2007 and
2,918 will vest subject to the continued service of one of our directors following the 2008 Annual Meeting of Stockholders. The 3,564 shares granted will vest subject to the continued service of the directors following the 2008 Annual Meeting of
Stockholders. The holders of these shares have full voting rights and will receive any dividends paid.

As of June 30, 2007, there was
$1,942,000 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 2.3 years. The total
fair value of shares vested during the three months ended June 30, 2007 and 2006, was $295,000 and $139,000, respectively. The weighted-average grant date fair value of restricted stock granted during the six months ended June 30, 2007 was
$15.84.

We recorded compensation expense totaling $257,000 and $415,000 related to the amortization of the restricted stock grants for the
three and six months ended June 30, 2007, respectively, and $144,000 and $252,000 for the three and six months ended June 30, 2006, respectively. The total income tax benefit recognized in the statement of operations related to this
compensation expense was $104,000 and $168,000 for the three and six months ended June 30, 2007, respectively, and $26,000 and $46,000 for the three and six months ended June 30, 2006.

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. 666,668 of these incentive unit awards are vesting over a three-year period, with one part of the incentive units vesting one-third on
each of the first, second, and third anniversary dates of the grant, and 63,335 vest in full on the third anniversary of the date of grant, subject to continued services and the terms of the Incentive Plan. On February 2006 we issued 120,000
incentive units to certain executives, these units vest on the third anniversary of the grant date. In March 2007 we issued an additional 183,336 incentive units to certain executives, these units vest over a three year period, with one third
vesting each on the first, second, and third anniversary dates of the grant.

We recorded compensation expense totaling $757,000 and
$1,258,000 related to the amortization of the restricted stock grants for the three and six months ended June 30, 2007, respectively, and $1,848,000 for the three and six months ended June 30, 2006. As of June 30, 2007, there was
$3,317,000 of unrecognized compensation cost related to incentive units. The weighted-average grant date fair value of incentive units granted in the six months ended June 30, 2007 was $14.88.

Stock options

Under our Incentive Plan, we have
514,530 stock options outstanding as of June 30, 2007. Of the total options outstanding, 482,308 stock options vest at the rate of one third per year over three years and expire ten years after the date of commencement of vesting and the other
50,000 stock options vest 100% eighteen months from the date of grant. 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 2007 and 2006:



|                                |  |              |  |

As of June 30, 2007, there was $293,000 of total unrecognized compensation cost related to
the nonvested stock options. The cost is expected to be recognized over a weighted average period of 1.7 years. The total fair value of shares vested during the three months ended June 30, 2007 and 2006 was $302,000 and $385,000, respectively.
The weighted-average grant date fair value of options granted during the six months ended June 30, 2007 was $1.89. The options exercised during the three and six months ended June 30, 2007 had an intrinsic value of $26,000, and $72,000,
respectively.

We recorded compensation expense totaling $54,000 and $103,000 related to the stock options for the three and six months
ended June 30, 2007, respectively, and $38,000 and $75,000 for the three and six months ended June 30, 2006, respectively. The total income tax benefit recognized in the statement of operations related to this compensation expense was
$22,000 and $42,000 for the three and six months ended June 30, 2007, respectively, and $7,000 and $14,000 for the three and six months ended June 30, 2006, respectively.

7. 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 June 30, 2007, we held a 60.5% capital interest in the Operating Partnership. For the three and six months ended
June 30, 2007, we were allocated 45.1% and 56.0% of the income and losses from the Operating Partnership.

Our effective tax rate is
44.5% and 44.3%, respectively, for the three and six months ended June 30, 2007. The higher effective tax rate compared to the federal statutory rate of 35% is primarily due to state taxes, net of federal tax expense.

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.

In June 2006, the FASB issued Financial Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48), which 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 files U.S. federal income tax returns and returns in various states jurisdictions. The
Companys policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense.

The Company adopted the provisions of FIN 48 on January 1, 2007, which resulted in unrecognized tax benefits of approximately $10.2 million, of which $134,000 was recorded as a reduction to the opening balance of retained
earnings, and if recognized, would effect our effective tax rate. As of January 1, 2007, the Company has recorded $227,000 of accrued interest with respect to unrecognized tax benefits. For the six months ended June 30, 2007, the Company
has recorded $161,000 of accrued interest with respect to the unrecognized tax benefits. We have not recorded any penalties with respect to unrecognized tax benefits.

At this time, we are unable to estimate the amount of unrecognized tax benefits for tax positions that may increase or decrease within the next 12 months.

8. 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 at June 30, 2007 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, rents and other receivables, due from affiliate, accounts
payable and other liabilities approximate fair value because of the short-term nature of these instruments.

As of June 30, 2007, the
fair value of our mortgage and other secured loans and unsecured loan aggregates $347,914,000, compared to the aggregate carrying value of $352,915,000.

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, 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.

Tenant reimbursements.Revenues increased by $487,000, or 10.5%, to $5.1 million for the three months ended June 30, 2007
compared to $4.6 million for the three months ended June 30, 2006 primarily due to an increase in recoverable expenses.

for two tenants in One Commerce Square which were recognized during 2006, offset by an increase of $38,000 due to after hours parking revenue resulting from a special event near one of our properties.

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 decreased by $192,000, or 8.1%, to $2.1 million for the three months ended June 30, 2007 compared to
$2.4 million for the three months ended June 30, 2006. The decrease was primarily due to a reduction of approximately $126,000 in leasing commissions and $49,000 in advisor fees from properties we manage on behalf of CalSTRS.

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 increased by $1.1 million, or 27.4%, to $5.3 million for the three months ended June 30, 2007 compared to $4.2 million for the three months ended June 30, 2006. This increase was primarily a result of an increase in fee
income of $194,000 related to the properties in Fairfax, Virginia acquired on January 31, 2007 by our joint venture with CalSTRS, and $1.4 million related to the Austin properties acquired on June 1, 2007 by our joint venture with CalSTRS,
Lehman and other institutional investors, offset by a decrease of $740,000 related to the City West Place acquisition fee recorded in June 2006. There was also an increase of approximately $119,000 in payroll reimbursements due to the purchase of
additional properties.

Rental property operating and maintenance expense.Rental property operating and maintenance expense
remained consistent at $4 million for each of the three month periods ended June 30, 2007 and 2006.

Real estate taxes.Real estate taxes remained consistent at $1.5 million for each of the three month periods ended June 30, 2007 and 2006.

Investment advisory, management, leasing and development services expenses.Expenses for these services increased by $1.6 million, or 71.2%, to $3.9 million for the three months ended June 30, 2007 compared to $2.3 million for
the three months ended June 30, 2006, primarily as a result of an increase in salaries and employment related costs due to an increase in the number of personnel, as well as an increase in various professional services costs.

Interest expense. Interest expense decreased by $1.5 million or 28.3% to $3.8 million for the three months ended June 30, 2007 compared to
$5.3 million for the three months ended June 30, 2006. The decrease is primarily due to capitalized interest of $1.2 million during the three months ended June 30, 2007, related to the Campus El Segundo and Murano development properties.
In addition there was a decrease in interest expense relating to Two Commerce Square of $209,000 for the three months ended June 30, 2007 as compared to the three months ended June 30, 2006, primarily due to the amortizing loan balances
for the mortgage and mezzanine loans.

Depreciation and amortization expense. Depreciation and amortization expense remained
consistent at $3 million for each of the three month periods ended June 30, 2007 and 2006.

General and administrative. General
and administrative expense increased by $81,000, or 1.6%, to $5.1 million for the three months ended June 30, 2007 compared to $5.0 million for the three months ended June 30, 2006. The increase is primarily due to an increase in salaries
and employment related costs due to an increase in the number of personnel, offset by a decrease in stock compensation expense recognized of $961,000 related to the incentive units, a decrease in leasing expenses of approximately $255,000 relating
to property investments in Houston and a decrease of $191,000 in City of Philadelphia business taxes due to a 2006 tax adjustment.

Gain
on sale of real estate.Gain on sale of real estate was $1.4 million for the three months ended June 30, 2007 due to the recognition of deferred gain on infrastructure costs incurred related to the sale of a 14.1 acre parcel at Campus El
Segundo in 2006. The parcel was sold for $24.6 million resulting in a total gain of $18.4 million. We are obligated to fund certain infrastructure improvements of approximately $2.7 million with respect to the development of the sold parcel;
therefore we recorded a deferred gain of $8.1 million. The remaining deferred gain as of June 30, 2007 was $5.4 million, which will be recognized as we complete infrastructure improvements on a percentage of completion basis.

Interest income. Interest income increased by $1.1 million, or 189.8%, to $1.7 million for the three months ended June 30, 2007 compared to
$597,000 for the three months ended June 30, 2006, primarily due to higher average cash balances and interest rates.

Aggregate revenue and operating and other expenses for unconsolidated real estate entities for the
three months ended June 30, 2007 compared to the three months ended June 30, 2006 increased primarily due to the acquisition of our interests in City West Place in June 2006, the two properties in Fairfax, Virginia in January 2007 and the
Austin properties in June 2007.

Aggregate interest expense increased by $12.7 million, or 102.1%, to $25.1 million for the three months
ended June 30, 2007 compared to $12.4 million for the three months ended June 30, 2006 primarily as a result of an increase in interest expense of $2.9 million relating to the debt obligations of City West Place, $2.3 million relating to
the debt obligations of the Fairfax, Virginia properties and $4.7 million relating to the debt obligations of the Austin properties. The increase was also due to refinancing of the City National Plaza mortgage and mezzanine loans in July 2006,
resulting in higher additional borrowings in 2007, which resulted in an increase in interest expense of $2.3 million.

Aggregate
depreciation and amortization expense increased by $6.8 million, or 47.6%, to $21.0 million for the three months ended June 30, 2007 compared to $14.2 million for the three months ended June 30, 2006 primarily as a result of
additional depreciation and amortization expense of $1.6 million due to the acquisition of City West Place in June 2006, $2.1 million due to the acquisition of two properties in Fairfax, Virginia in January 2007 and $5.2 million due to the
acquisition of the Austin properties in June 2007. In addition, there was a decrease of $2.4 million for the Houston properties primarily due to the expiration of purchased in-place lease values.

Comparison of six months ended June 30, 2007 to six months ended June 30, 2006

Rental revenues. Rental revenue remained consistent at $16 million for each of the six month periods ended June 30, 2007 and 2006.

Tenant reimbursements.Revenues increased by $765,000, or 8.0%, to $10.3 million for the six months ended June 30, 2007
compared to $9.5 million for the six months ended June 30, 2006 primarily due to an increase in recoverable expenses.

Parking and
other revenues. Revenues decreased by $258,000, or 11.6%, to $2 million for the six months ended June 30, 2007 compared to $2.2 million for the six months ended June 30, 2006 primarily due to lease termination fees of $427,000 for two
tenants in One Commerce Square which were recognized during 2006, offset by an increase of $215,000 in the first six months of 2007 due to after hours parking revenue resulting from a special event near one of our properties.

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 increased by $597,000, or 15.8%, to $4.4 million for the six months ended June 30, 2007 compared to $3.8 million for the six months ended June 30,
2006. The increase was primarily due to an increase in development fees of approximately $994,000 relating to a professional services agreement with NBC Universal, Inc. to advise on a plan for future development at its Universal City property in Los
Angeles. This ongoing agreement was entered into in March 2006 resulting in four months of revenues in the six months ended June 30, 2006 compared to a full six months for the comparable period of 2007. This was offset by decreases of approximately
$130,000 in leasing commissions and approximately $120,000 in advisor fees from properties we manage on behalf of CalSTRS.

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 increased by $3.3 million, or 52.5%, to $9.7 million for the six months ended June 30, 2007
compared to $6.3 million for the six months ended June 30, 2006. This increase was primarily a result of an increase in fee income of $953,000 related to the property investments in Fairfax, Virginia acquired on January 31, 2007 by our

venture with CalSTRS and $1.4 million related to the Austin portfolio investments acquired June 1, 2007 by our joint venture with CalSTRS, Lehman and
other institutional investors, offset by a decrease of $309,000 related to the City West Place acquisition fee recorded in June 2006. The increase was also due to an increase in leasing commissions of $310,000 and an increase in fee income of
$755,000 relating to City National Plaza. There was also an increase of approximately $294,000 in payroll reimbursements due to the purchase of additional properties.

Rental property operating and maintenance expense.Rental property operating and maintenance expense remained consistent at $8 million for each of the six month periods ended June 30, 2007 and 2006.

Real estate taxes.Real estate taxes remained consistent at $3 million for each of the six month periods ended June 30,
2007 and 2006.

Investment advisory, management, leasing and development services expenses.Expenses for these services increased by
$2.2 million, or 52.8%, to $6.3 million for the six months ended June 30, 2007 compared to $4.1 million for the six months ended June 30, 2006, primarily as a result of an increase in salaries and employment related costs due to an
increase in the number of personnel, as well as an increase in various professional services costs.

Interest expense. Interest
expense decreased by $2.7 million or 25.2% to $8.0 million for the six months ended June 30, 2007 compared to $10.8 million for the six months ended June 30, 2006. The decrease is primarily due to capitalized interest of $2.0 million
during the six months ended June 30, 2007, related to Campus El Segundo and Murano development properties. In addition there was a decrease in interest expense relating to Two Commerce Square of $412,000 for the six months ended June 30,
2007 as compared to the six months ended June 30, 2006, primarily due to the amortizing loan balances for the mortgage and mezzanine loans.

Depreciation and amortization expense. Depreciation and amortization expense remained consistent at $6 million for each of the six month periods ended June 30, 2007 and 2006.

General and administrative. General and administrative expense increased by $1.9 million, or 23.3%, to $10.2 million for the six months ended
June 30, 2007 compared to $8.3 million for the six months ended June 30, 2006. The increase is primarily due to an increase in salaries and employment related costs due to an increase in the number of personnel. This was offset by a
decrease in professional fees of approximately $344,000 and a decrease in stock compensation expense recognized of $398,000, related to the incentive units.

Gain on sale of real estate.Gain on sale of real estate was $2.4 million for the six months ended June 30, 2007 due to the recognition of deferred gain on infrastructure costs incurred related to the sale
of a 14.1 acre parcel at Campus El Segundo in 2006. The parcel was sold for $24.6 million resulting in a total gain of $18.4 million. We are obligated to fund certain infrastructure improvements of approximately $2.7 million with respect to the
development of the sold parcel; therefore we recorded a deferred gain of $8.1 million. The remaining deferred gain as of June 30, 2007 was $5.4 million, which will be recognized as we complete infrastructure improvements on a percentage of
completion basis.

Interest income. Interest income increased by $1.3 million, or 102.0%, to $2.6 million for the six months ended
June 30, 2007 compared to $1.3 million for the six months ended June 30, 2006, primarily due to higher average cash balances and interest rates.

##### Table of Contents

Aggregate revenue and operating and other expenses for unconsolidated real estate entities for the six
months ended June 30, 2007 compared to the six months ended June 30, 2006 increased primarily due to the acquisition of our interests in City West Place in June 2006, the two properties in Fairfax, Virginia in January 2007 and the Austin
portfolio in June 2007.

Aggregate interest expense increased by $20.9 million, or 90.8%, to $44.0 million for the six months ended
June 30, 2007 compared to $23.0 million for the six months ended June 30, 2006 primarily as a result of an increase in interest expense of $6.3 million relating to the debt obligations of City West Place, $4.0 million relating to the debt
obligations of the Fairfax, Virginia properties and $4.7 million relating to the debt obligations of the Austin properties. The increase was also due to refinancing of the City National Plaza mortgage and mezzanine loans in July 2006, resulting in
higher additional borrowings in 2007, which resulted in an increase in interest expense of $5.1 million.

Aggregate depreciation and
amortization expense increased by $9.7 million, or 36.6%, to $36.2 million for the six months ended June 30, 2007 compared to $26.5 million for the six months ended June 30, 2006 primarily as a result of additional depreciation and
amortization expense of $3.9 million due to the acquisition of City West Place in June 2006, $3.7 million due to the acquisition of the two Fairfax, Virginia properties in January 2007 and $5.2 million due to the acquisition of the Austin properties
in June 2007. In addition, there was an increase of $1.7 million for City National Plaza due to new assets placed into service in 2007, offset by a decrease of $3.6 million for the Houston properties and $890,000 for the Montgomery County properties
primarily due to the expiration of purchased in place lease values.

Liquidity and Capital Resources

Analysis of liquidity and capital resources

As of June 30, 2007, we have unrestricted cash and cash equivalents of $144.2 million. Our management believes that our company will have sufficient capital to satisfy our liquidity needs over the next 12 months through cash on hand,
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. Additionally, as noted elsewhere herein, on April 25, 2007, we sold 9,200,000 shares of common stock, pursuant to an effective registration statement previously filed with the Securities and Exchange Commission, at
$16.00 per share. We received net proceeds, after deducting underwriting discounts and commissions, offering expenses and redemption of units in our operating partnership held by our Chief Executive Officer and President and one of our other senior
executives, of $105.6 million. 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.

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 covenants containing 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 arrangement. With respect to our joint venture properties, we
do not 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, future financing arrangements we may enter into may contain
restrictions on our use of cash generated from our properties.

Development and Redevelopment Projects

We currently own interests in four development projects and our joint venture with CalSTRS includes nine redevelopment and two development sites. We have
considerable expertise in the completion of large-scale development and redevelopment projects. The construction of Murano, a 302 unit high-rise residential condominium project, commenced in the second quarter of 2006. We expect construction to be
substantially complete in the second quarter of 2008. We anticipate developing the other development projects as market feasibility permits. We also anticipate seeking to mitigate development risk by obtaining significant pre-leasing and guaranteed
maximum cost construction contracts. Our redevelopment projects are primarily financed through property-level bank financing. There can be no assurance we will be able to successfully implement these risk mitigation measures.

##### Table of Contents

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. In July 2006, a parent of the entity that owns City National Plaza
refinanced the loan for City National Plaza, which provides proceeds to cover the future redevelopment costs. In August 2006, the entity developing Murano obtained a $142.5 million construction loan, and in September 2006, we borrowed $17.4 million
to finance our preferred equity position in this property. We are obligated to fund our preferred equity to Murano to pay construction costs before we can draw the construction loan. We met this obligation during the quarter ended March 31,
2007, and began making draws on the construction loan. The balance on the construction loan was $25.5 million as of June 30, 2007. If we are unable to sell the condominium units upon completion or 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.

In June 2007, we closed on a construction loan in the amount of $42.7 million to
finance the development of two office buildings totaling 200,000 square feet at Four Points Centre. We commenced construction in June 2007, and as of June 30, 2007, we had drawn funds totaling $253,000. We expect to be substantially complete
with these two buildings in the third quarter of 2008.

Leasing, Tenant Improvement and Capital Needs

In addition to our development and redevelopment projects, our company also owns majority interests in One Commerce Square and Two Commerce Square. These
properties are substantially leased and have significant stabilized cash flows. 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. Based upon historical expenditure levels, the leasing activity for the properties and the current rent
roll, we anticipate incurring expenditures of approximately $7.5 million in capital improvements, tenant improvements, and leasing costs for the One Commerce Square and Two Commerce Square properties collectively during the remainder of 2007 and
2008.

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.

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

As of June 30, 2007, our company had investments in entities owning unconsolidated properties with stated ownership percentages ranging from 6.25% to
50.0%. We do not have control of these entities, and none of the entities are considered variable interest entities in accordance with the Financial Accounting Standard Boards revision to Interpretation No. 46. Therefore, we account for
them using the equity method of accounting. The table below summarizes the outstanding debt for the unconsolidated properties as of June 30, 2007 (in thousands). We have not guaranteed any of the debt.

Cash Flows

Comparison of six months ended June 30, 2007 to six months ended June 30, 2006

Cash and cash equivalents were
$144.2 million as of June 30, 2007 and $29.0 million as of June 30, 2006.

Operating Activities - Net cash used in operating
activities increased by $15.0 million to $18.3 million for the six months ended June 30, 2007 compared to $3.3 million for the six months ended June 30, 2006. The increase was primarily the result of an increase in changes in assets and
liabilities of $9.8 million, a increase in net income of $2.7 million and an increase in minority interest of $3.1 million. The increases were offset by an increase in gain on sale of asset of $2.4 million.

##### Table of Contents

Investing Activities - Net cash used in investing activities increased by $32.2 million to $61.6 million
for the six months ended June 30, 2007 compared to $29.4 million for the six months ended June 30, 2006. The increase was primarily the result of an increase in real estate improvements of $37.8 million, an increase in contributions from
unconsolidated real estate entities of $12.0 million and an increase in change in restricted cash of $5.1 million. The increases were offset by a decrease of $24.2 million used for the purchase of interests in unconsolidated real estate entities

Financing Activities - Net cash provided by (used in) financing activities increased by $132.0 million to $123.2 million for the six
months ended June 30, 2007 compared to $(8.8) million for the six months ended June 30, 2006. The increase was primarily the result of proceeds from our April 2007 public offering, net of offering costs, of $139.4 million as well as draws
on the Murano construction loan of $25.8 million. In addition, there were no minority interest distributions for the six months ended June 30, 2007 compared to $550,000 for the six months ended June 30, 2006. The increases were offset by a
decrease of $33.6 million related to payments for the redemption of operating units.

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 residential property and are in the process of developing Murano, another residential property. The existing residential property is located in the Philadelphia central business district and subject to short-term leases. Our
residential property under development represents units for sale, and is also in the Philadelphia central business district. 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. We intend to mitigate this risk by seeking to maintain a target consolidated debt-to-gross assets ratio of approximately 60%, while continuously evaluating all available debt and equity resources and following
established risk management policies and procedures. 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 June 30, 2007, our company had $64.2
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 $2,121.2 million, of which $1,029.5 million bears interest at floating rates. As of June 30, 2007, interest rate caps have been purchased for all of these floating rate loans.

Our fixed and variable rate consolidated long-term debt at June 30, 2007 consisted of the following (in thousands):

We utilize sensitivity analyses to assess the potential effect of our variable rate debt. At
June 30, 2007, our consolidated variable rate long-term debt represents 18.2% of our total long-term debt. If interest rates were to increase by 75 basis points, or by approximately 10% of the weighted average variable rate at June 30,
2007, the net impact would be increased interest costs of $482,000 per year.

As of June 30, 2007, the fair value of our mortgage and
other secured loans and unsecured loan aggregate $347.9 million, compared to the aggregate carrying value of $352.9 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 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.

In connection with our Section 404 compliance effort, we continue to address certain internal control deficiencies by, among other things,
improving our financial statement close and reporting process and improving review and monitoring controls. All of these initiatives are being conducted under the oversight of the Audit Committee and senior management.

Internal Controls over Financial Reporting

There was
no change 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 six months ended June 30, 2007 that has materially affected, or is reasonably likely to
materially affect, internal control over financial reporting. From time to time, we may make changes in our companys internal control processes in the future.

PART II. OTHER INFORMATION

ITEM 1A. RISK FACTORS

Risks Related to Our Properties and Our Business

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 our joint venture with Lehman, provide us with substantial fee revenues. For the six months ended June 30, 2007 and 2006,
approximately 26.3% and 21.1 %, respectively, of our revenue has been derived from fees earned from these relationships.

We cannot
assure you that our relationships with CalSTRS will continue and we may not be able to replace these relationships with another strategic alliance that would provide comparable revenues. Our interest in our CalSTRS joint venture 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 an event 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
Mr. Thomas 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. Our Operating Partnership has the ability to initiate the buy-sell provision upon an event of default of CalSTRS, such as a failure to contribute capital in accordance with capital calls. Upon the occurrence of a Buyout Default, the
non-defaulting member may elect to purchase the other members joint venture interest based on a three percent discount to the appraised fair market value.

##### Table of Contents

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, 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 third parties 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 August 9, 2007, we hold interests in 12 of our properties through our joint venture with CalSTRS and 10 of our properties through a joint
venture with CalSTRS, Lehman and other institutional investors. Our joint venture with 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.

Our joint venture entity with CalSTRS is the general partner of the partnership that owns ten properties in Austin. The limited partners in the Austin
partnership have certain approval rights similar to CalSTRS rights described above. 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 for certain acts. These rights could adversely affect us.

We may not be able to find syndication investors for our joint venture with Lehman

We have entered into a partnership agreement and syndication agreement with Lehman in relation to our joint venture that owns 10 properties in Austin, Texas that requires us to syndicate a significant portion of
Lehmans current equity position within a period up to a year post-closing of the acquisition of the Austin, Texas portfolio. On July 5, 2007, 33% of Lehmans equity in the joint venture was purchased by an unrelated institutional
investor. There is a risk that we will be unable to successfully sell Lehmans remaining equity to investors. The consequences of a failed syndication are that certain fees on any unsold equity such as promote, administration fees and
disposition fees could be reduced or eliminated for us, and Lehman will retain control rights with respect to major decisions of the joint venture.

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

As of
June 30, 2007, the 20 largest tenants for properties in which we hold an ownership interest collectively leased 34.8% of the rentable square feet of space, representing 62.4% 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 the substantial majority of space at Two Commerce Square and accounted for approximately 18.5% of the total annualized
rent generated by all of our consolidated and unconsolidated properties as of June 30, 2007. In addition, Conrails rental revenues and tenant reimbursements accounted for approximately 31.7% of total consolidated revenue for the year
ended December 31, 2006. Our existing lease



28

##### Table of Contents

with Conrail expires in two stages in 2008 and 2009. Conrail has subleased substantially all of its space under lease, and we have entered into direct lease
agreements with many of these sublease tenants. However, these new leases are at lower rental rates, and we expect to experience a substantial decline in rental revenues from Two Commerce Square when the existing lease with Conrail expires.

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. 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 and prevents us from leasing that 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.

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, such as business layoffs or downsizing, industry slowdowns, relocations of businesses, changing demographics, increased telecommuting, 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 the national and regional office space market such as 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 level reduces cash available to
fund business growth and may expose us to the risk of default under our debt obligations.

As of June 30, 2007, our total
consolidated indebtedness is approximately $352.9 million. In addition, we own interests in unconsolidated entities subject to total indebtedness in the amount of $2.1 billion as of June 30, 2007. 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.

Additionally, the Operating Partnership has guaranteed the loans on our Four Points Centre property up to a maximum amount of $5.4
million and $42.7 million. Furthermore, a subsidiary of the Operating Partnership pledged its preferred equity interest in Murano to a lender in the amount of $17,434,000. The Operating Partnership has guaranteed this loan. Mr. Thomas
guarantees approximately $7.5 million of the mezzanine loans for Two Commerce Square, and we have accordingly agreed to indemnify Mr. Thomas in the event his guarantees are called upon. We may incur significant additional debt to finance

future acquisition and development activities. It is possible the required payments of principal and interest on borrowings may leave us with insufficient
cash to operate our properties profitably. Our 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 anticipate that a significant portion of our debt will bear interest at variable rates, and in the event we do not purchase interest rate caps for floating rate
debt in the future, increases in interest rates could materially increase our interest expense;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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, 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. In addition, foreclosures could also result in our being liable under the terms of our
indemnification agreement with Mr. Thomas if we were required to sell all or a portion of our interests in One Commerce Square or Two Commerce Square.

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 June 30, 2007, $64.2 million of our consolidated debt and $1.0 billion of our unconsolidated debt was at variable interest rates. As of
June 30, 2007, interest rate caps have been purchased for all of the floating rate loans.

We intend to generally limit our exposure
to interest rate volatility by using interest rate hedging arrangements and swap agreements to cap our interest rate exposure. These arrangements 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 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.

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 the top 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 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;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | 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;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | 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.

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.

We have a
near-term expectation of significant growth, and we may not be able to adapt our management and operational systems to respond to this growth, including the acquisition and integration of additional properties without unanticipated disruption or
expense.

We purchased an interest in properties located in Houston, Texas with an aggregate of 1.5 million rentable square feet in
2006 and, in February 2007, an interest in properties in Fairfax, Virginia totaling approximately 586,000 rentable square feet. In addition, we commenced construction of our Murano project in Philadelphia, a high-rise residential tower in 2006. We
expect construction to be substantially complete in the second quarter of 2008. In March 2007 we entered into an

##### Table of Contents

agreement through a joint venture to purchase an interest in properties located in Austin, Texas with an aggregate of 3.5 million square feet. In order
to achieve desired and planned business growth, we intend to continue to significantly expand our asset and property management activities, and acquire a significant number of properties in the next 12 to 24 months. With the expected growth of our
portfolio, we cannot assure you that we will be able to adapt our management, administrative, accounting and operational systems, or hire and retain sufficient operational staff to integrate these properties into our portfolio and manage these
additional properties without operating disruptions or unanticipated costs. The acquisition of additional properties would generate additional operating expenses. As we acquire additional properties, we will be subject to risks associated with
managing new properties, including tenant retention and mortgage default. Our failure to successfully integrate any future acquisitions into our portfolio 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.

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;
| | - |  | --------------------------------------------------------------------------------



| |  |  | 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;

If we are not successful in our property development initiatives, including our Murano, Four Points Centre, Campus El Segundo and City West Place
projects, this 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. Further, our Murano project is the development of a high-rise residential condominium building. Historically, our development and property management activities have centered on office properties. In developing and managing
a residential project, we may encounter unfamiliar problems that adversely impact our ability to complete the project on a timely basis and derive sustainable revenues from the property.

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 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 June 30, 2007, leases representing 5.3% and 8.9% of the rentable square feet of the office and
mixed-use properties in which we hold an ownership interest will expire in the remainder of 2007 and 2008, respectively. Further, an additional 13.7% of the square feet of these properties was available for lease on that date. Rental rates 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. In particular, a significant amount of space at our Two Commerce Square property has historically been leased to
Conrail. This lease expires in two stages in 2008 and 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 2008 and 2009. If we are unable to
lease the remaining portion of the space currently leased by Conrail in Two Commerce Square prior to the expiration of the lease and assuming all subtenants to the Conrail lease exercise no renewal options and exercise all early termination options,
our rental revenue (excluding tenant reimbursements revenue) computed in accordance with accounting principles generally accepted in the United States of America (GAAP) would decrease by $2.8 million in 2008 as compared to 2007, $2.5
million in 2009 as compared to 2008, and $1.7 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. 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 for the short term. Our access to third-party sources of capital depends, in part, on:



| |  |  | our current debt levels, which were $352.9 million of consolidated debt and $2.1 billion of unconsolidated debt as of June 30, 2007;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our current cash flow from operating activities, which was $17.5 million for the six months ended June 30, 2007;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | 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.

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. With respect to properties in which we hold an ownership interest, we have
not obtained any recent environmental reports regarding conditions at the properties, nor do we intend to. 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, by signs and labels, of 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 those exercising control over a buildings management 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 two of our properties in which we hold an ownership interest. At our 2100 JFK
Boulevard 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. We undertook remedial procedures for the gasoline spill
and other contaminants, including removing contaminated soil. As of December 31, 2006, all soil remediation work has been completed. Our lease required the tenant (or its successor in interest) to indemnify us against all costs and expenses of
every kind relating directly or indirectly to the tenants use and occupancy of the premises. We initiated litigation against the former tenant to enforce its obligation to us under the indemnity provisions of the lease. On April 10, 2007,
the lawsuit was settled in our favor for $1,750,000. With respect to asbestos materials present at our City National Plaza property, these materials have been removed or abated from certain tenant and common areas of the building structure. We
continue to remove or abate asbestos materials from various areas of the building structure and as of June 30, 2007, have accrued $3.0 million for such estimated future costs.



34

##### Table of Contents

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.

We are subject to high taxes relating to our Texas and Philadelphia properties that could negatively affect our operating results and may also be
adversely affected by new legislation.

In 2006, the Texas legislature enacted a change in that states tax structure that took
effect on January 1, 2007 and replaced the Texas franchise tax with a margin tax on gross receipts. The new tax is imposed on an extended base (including partnerships, joint ventures and other entities as well as corporations) and
will be calculated on a combined basis, taking into account the receipts of all members of an affiliated group when one or more members have business presence in the State of Texas. The taxable margin is calculated using one of three
methods and is then apportioned to Texas using a factor of Texas receipts to total receipts. The calculation methods to be used are not advantageous to capital intensive businesses such as large commercial property owners and therefore may
negatively impact such businesses. The new tax structure has been challenged by various groups and entities and may be changed or repealed. We have not evaluated the impact of this tax on our financial condition, results of operations or cash flow.

In Philadelphia, two downtown development sites of which a substantially-leased office tower has been built on one of the sites, have each
been designated as a Keystone Opportunity Improvement Zone site by the state of Pennsylvania. This designation confers upon occupants a 15-year abatement of all state and local taxes except the city wage tax. The second site, if developed, along
with the office tower already developed on the first site, could, depending on overall supply-demand fundamentals, have a negative impact on central business district Philadelphia rental rates and building values. Further, the transfer tax rate in
the City of Philadelphia, which we could incur upon a sale of one of our properties, is one of the highest in the United States and could be a very significant cost in the event of the sale of one of our Philadelphia properties. In Philadelphia,
transfers of fee title or partnership interests representing 90% or more of property ownership are subject to a tax of 4% of the transaction price. The 4% amount is comprised of a 3% levy by the City of Philadelphia and a 1% charge by the
Commonwealth of Pennsylvania. The transaction price, if not specifically disclosed to the taxing authorities, must be deemed reasonable, and is therefore typically the assessed value of the property for real estate tax purposes.

The risk of future terrorist attacks in the United States could harm the demand for and the value of our properties which are located in major metropolitan areas.

The risk of future terrorist attacks in the U.S. or war could harm the demand for and the value of our properties. We manage properties
that are well-known landmarks in high visibility metropolitan areas that may be perceived as more likely terrorist targets than lower profile properties in less commercial areas, which could potentially reduce the demand for and value of these
properties. A decrease in demand could make it difficult for us to renew leases or re-lease our properties at rates equal to or above historical lease rates.

Terrorist attacks also could directly impact the value of our properties through damage, destruction, loss or increased security costs. Further, the availability of insurance for acts of terrorism may be limited or
may cost more. The three operating properties in which we own interests located in Philadelphia, Pennsylvania  One Commerce Square, Two Commerce Square and 2121 Market Street  are located within a three city block area. Together, these
three properties represented approximately 31.6% of the annualized rent for properties in which we hold an ownership interest as of June 30, 2007. Our Murano residential high-rise project which is currently under construction is also located
within the same three city block area. Because these properties are located closely together, a catastrophic event in this area could materially damage, destroy or impair the use by tenants of all of these properties. To the extent that our tenants
and prospective buyers of condominium units are impacted by future attacks, their ability to continue to honor obligations under their existing leases and purchase contracts with us could be adversely affected, including being unable to make timely
rental payments and defaulting under existing leases and purchase contracts. Additionally, some tenants have termination rights in respect of certain casualties. Under the terms of our financing documents, we may be required to apply casualty
proceeds to repay loans and may not be able to rebuild or restore the property unless we are able to obtain alternate financing. If we are entitled to receive casualty proceeds, we may not be able to rebuild or restore the property, and we may be
forced to recognize taxable gain on the affected property. Failure to reinvest casualty proceeds in the affected property or properties could also result in obligations under our tax indemnification agreement with Mr. Thomas.

##### Table of Contents

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 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 31.3% of annualized rent for properties in which we hold an ownership interest as of
June 30, 2007. This indemnification period will expire in October 2008, unless Mr. Thomas and related entities contribute the remaining 11% minority interest in each of One Commerce Square and Two Commerce Square to us prior to
October 13, 2008 for not more than $4 million in the aggregate, in which event the indemnification period will expire on October 13, 2013, which may be 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

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;
| | - |  | ---------------------------------------



| |  |  | 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; and
| | - |  | --------------------------------------------------------



| |  |  | changing submarket demographics.
| | - |  | --------------------------------

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 the 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. Although we believe that the properties in which we hold an ownership interest substantially comply with the requirements of the ADA, we have not conducted a portfolio-wide investigation to
determine our compliance. 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.

##### Table of Contents

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, 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 sole 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. 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 June 30, 2007, Mr. Thomas owns or controls a very significant interest in our operating partnership consisting
of 14,496,666 units, or a 40% interest including outstanding shares of common stock and units (including incentive units held by senior executive officers) as of such date. Mr. Thomas also owns 206,667 shares of restricted stock. In addition,
our senior executive officers collectively hold an interest in Operating Partnership units and incentive units aggregating a 40% interest in our company including outstanding shares of common stock and units, vested and unvested.

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 and other matters.
| | - |  | -------------------------------------------------

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 would 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



37



---

##### Table of Contents

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 ownership 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 37% of our outstanding voting stock as of June 30, 2007. Although not entitled to dividends or other distributions, these limited voting shares are entitled to one vote
per share in the election of directors, 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 25 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. In addition, Mr. Thomas is 70 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. 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.

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. No shares of preferred stock are outstanding and we have no present plans to issue any preferred stock. The issuance of any preferred stock, however, could diminish the
rights of holders of our common



38

##### Table of Contents

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.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

At our companys 2007 annual meeting of its stockholders held on May 30, 2007 in Los Angeles, California, our stockholders elected James A.
Thomas (26,669,347 votes for and 272,458 votes against), R. Bruce Andrews (26,064,352 votes for and 877,453 votes against), Edward D. Fox (26,050,552 votes for and 891,253 votes against), Winston H. Hickox (26,788,505 votes for and 153,300 votes
against), John L. Goolsby (26,788,505 votes for and 153,300 votes against), Randall L. Scott (26,536,747 votes for and 405,058 votes against), and John R. Sischo (26,536,747 votes for and 405,058 votes against), as directors of our company each to
serve a one-year term expiring following our annual meeting in 2008. Stockholders also ratified the selection of Ernst & Young LLP as our independent auditors for the fiscal year ended December 31, 2007 (12,391,313 votes for and 53,826
votes against). In addition, stockholders approved the amendments of the Companys 2004 Equity Incentive Plan (12,391,313 votes for and 53,826 votes against).
