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.

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 in which we were considered to be the primary beneficiary of an entity that we determined to be a variable interest entity. The Financial Accounting Standards Board (FASB) issued Accounting
Standards Codification (ASC) 810, Consolidation, which provides guidance on the identification of entities for which control is achieved through means other than voting rights (variable interest entities or
VIEs) and the determination of which business enterprise, if any, should consolidate the VIE (the primary beneficiary). 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.

We have a $29.1 million preferred equity interest in Murano, an investment which we consolidate. In
addition to our preferred equity, there is a priority interest of $8.5 million of which $7.3 million is due to us and $1.2 million is due to our partner. Excluding our preferred equity interest and the priority interest, our partner has a 27.0%
ownership interest in Murano which we record as a noncontrolling interest (partners in consolidated real estate entities).

Income (Loss)
Per Share

The computation of basic income (loss) per share is based on net income (loss) and the weighted average number
of shares of our common stock outstanding during the period. The computation of diluted income (loss) per share includes the assumed exercise of outstanding stock options and the effect of the vesting of restricted stock and incentive units that
have been granted to employees in connection with stock based compensation, all calculated using the treasury stock method. In accordance with FASB ASC 260-10-45, Earnings Per Share, the Companys unvested restricted stock and
unvested incentive units are considered to be participating securities and are included in the computation of earnings per share to calculate a two class earnings per share. We only present the earnings per share attributable to the common
shareholders. See Note 5  Income (Loss) Per Share and Dividends Declared.

Development Activities

Project costs associated with the development and construction of a real estate project are capitalized on our balance sheet. 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 are transferred to operating properties, in the case of Murano, the costs capitalized are transferred to condominium units held for sale. Capitalized interest as of September 30, 2010 and December 31, 2009, is $19.1 million and
$19.6 million, respectively. No interest was capitalized for the nine months ended September 30, 2010.

Revenue Recognition -
Condominium Sales

We have one high-rise condominium project for which we used the percentage of completion accounting
method to recognize costs and sales during the construction period, up through and including June 30, 2009. Commencing with the third quarter of 2009, we applied the deposit method of accounting to recognize costs and sales. Under the
provisions of FASB ASC 360-20, Property, Plant and Equipment subsection Real Estate and Sales, revenue and costs for projects are recognized when all parties are bound by the terms of the contract, all consideration has been
exchanged, any permanent financing for which the seller is responsible has been arranged and all conditions precedent to closing have been performed. This results in profit from the sale of condominium units recognized at the point of settlement as
compared to the point of sale. Revenue is recognized on the contract price of individual units. Total estimated costs, net of impairment charges, are allocated to individual units which have closed on a relative value basis. Total estimated revenue
and construction costs are reviewed periodically, and any change is applied to current and future periods.

Forfeited customer
deposits are recognized as revenue in the period in which we determine that the customer will not complete the purchase of the condominium unit and when we determine we have the right to keep the deposit. No forfeitures were recognized in the nine
months ended September 30, 2010 while we recognized forfeiture revenue of $56,000 and $397,000 for the three and nine months ended September 30, 2009, respectively.

Impairment of Long-Lived Assets

We assess whether there has been
impairment in the value of our long-lived assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying
amount to the future net cash flows, undiscounted and without interest, expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of
the assets exceeds the fair value of the assets. Assets held for sale are reported at the lower of the carrying amount or fair value, less costs to sell. We record the Murano condominium units at the lower of cost or estimated fair value as the
condominium units meet the held for sale criteria of FASB ASC 360, Property, Plant, and Equipment. Included in Equity in net loss of unconsolidated real estate entities for the three and nine months ended September 30, 2009, is a
pre-tax, non-cash impairment charge of $2.0 million related to our joint venture investments. There was no corresponding charge for the three or nine months ended September 30, 2010. We recorded our share of the impairment loss at the joint
venture level as these investments met the other-than-temporary impairment criteria of FASB ASC 323, Investments  Equity Method and Joint Ventures.

Recent Accounting Pronouncements

Changes to U.S. generally accepted
accounting principles (GAAP) are established by the FASB in the form of accounting standards updates (ASUs) to the FASBs Accounting Standards Codification. We consider the applicability and impact of all ASUs. Newly
issued ASUs not listed below are expected to have no impact on our consolidated financial position and results of operations, because either the ASU is not applicable or the impact is expected to be immaterial.

In January 2010, the Company adopted FASB ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures
about Fair Value Measurements. ASU 2010-06 amends ASC 820 and clarifies and provides additional disclosure requirements related to recurring and non-recurring fair value measurements. The adoption of this accounting update did not have a
material impact on the Companys consolidated financial statements.

In January 2010, the Company adopted FASB ASC 810,
Consolidation. FASB ASC 810 revises the approach to determining the primary beneficiary of a variable interest entity to be more qualitative in nature and requires companies to more frequently reassess whether they must consolidate a
VIE. The amended VIE provisions of FASB ASC 810 are effective for interim and annual reporting periods beginning after November 15, 2009. The adoption of this accounting standard did not have a material impact on the Companys consolidated
financial statements.

In February 2010, the FASB issued ASU No. 2010-09, Subsequent Events (Topic 855):
Amendments to Certain Recognition and Disclosure Requirements. This standard amends the authoritative guidance for subsequent events that was previously issued and, among other things, exempts SEC registrants from the requirement to disclose
the date through which it has evaluated subsequent events for either original or restated financial statements. This standard does not apply to subsequent events or transactions that are within the scope of other applicable GAAP that provides
different guidance on the accounting treatment for subsequent events or transactions. The adoption of this ASU did not have a material effect on our financial position and results of operations as it only addresses disclosures.

Interim Financial Data

The accompanying unaudited interim financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities
and Exchange Commission (SEC). Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP may have been condensed or omitted pursuant to SEC rules and regulations, although
we believe that the disclosures are adequate to make their presentation not misleading. The accompanying unaudited financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present
fairly the financial information set forth therein. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ended December 31, 2010. The interim financial statements
should be read in conjunction with the consolidated financial statements and notes thereto in the Companys Annual Report on Form 10-K for the year ended December 31, 2009 and our subsequent Form 10-Q quarterly reports, each of which is
filed with the SEC.

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

The total capital commitment to the joint venture was $511.7 million, of which approximately $24.8 million and $19.0 million is currently
unfunded by CalSTRS and us, respectively.

A buy-sell provision may be exercised by either CalSTRS or us. Under this
provision, the initiating party sets a price for its interest in the joint venture, and the other party has a specified time to elect to either buy the initiating partys interest or to sell its own interest to the initiating party. Upon the
occurrence of certain events, CalSTRS also has a buy-out option to purchase our interest in the joint venture. The buyout price is based upon a 3% discount to the appraised fair market value.

During the second quarter of 2009, TPG/CalSTRS redeemed a 15% membership interest held by a noncontrolling owner in the City National
Plaza (CNP) partnership. The redemption price of $19.8 million was financed with a promissory note due in 2012.

During the first quarter of 2010, CalSTRS, our partner in CNP, acquired all of the propertys mezzanine debt. On July 6, 2010, CalSTRS contributed this debt to the equity in TPG/CalSTRS,
reducing the leverage on CNP by the full $219.1 million balance on the mezzanine loans. Solely with respect to the interest of TPG/CalSTRS in CNP, CalSTRS percentage interest increased from 75% to 92.1% and TPGs percentage interest
decreased from 25% to 7.9%. We are in discussions with CalSTRS to obtain an option to participate in up to an additional 17.1% interest in CNP through TPG/CalSTRS. On July 6, 2010, a subsidiary of TPG/CalSTRS that owns CNP entered into a new
non-recourse first mortgage loan in the amount of $350.0 million. The loan bears interest at a fixed rate of 5.9% and is for a term of ten years, to mature on July 1, 2020.

On October 19,
2010, TPG/CalSTRS invested $40.0 million as new equity in our Centerpointe partnership, which was used to retire $46.6 million of mezzanine debt, realizing a 14.2% discount from the face amount of the debt which included releasing loan reserves of
approximately $11.7 million held by the lenders to TPG/CalSTRS to use for capital needs at the property. This new equity, of which the Company contributed $2.0 million or 5%, will be treated as preferred equity. Prior to February 9, 2012, we
have the right to increase our interest percentage in preferred equity to 25%, and commensurately reduce CalSTRS interest percentage in preferred equity to 75%, by contributing to the Centerpointe partnership an amount equal to 20% of the face
amount of the retired debt, equal to approximately $9.3 million. The contribution to increase our interest percentage would be distributed to CalSTRS.

As of January 1, 2010, in connection with the adoption of the updated provisions of ASC 810, pursuant to FASB No. 167, which amends FIN 46(R), TPG/CalSTRS and the Austin Portfolio Joint Venture
were deemed to be variable interest entities for which we were not considered to be the primary beneficiary. In connection with the TPG/CalSTRS joint venture, CalSTRS and TPG acting together are considered to have the power to direct the activities
of the joint venture that most significantly impact the joint venture economic performance and therefore neither TPG nor CalSTRS is considered to be the primary beneficiary. We determined the key activities that drive the economic performance of the
joint venture to be (1) the acquisition and development of real estate (including capital improvements), (2) financing, and (3) leasing. In connection with these key activities, the TPG/CalSTRS venture agreement requires unanimous
approval by the two members.

In connection with the Austin Portfolio Joint Venture, TPG/CalSTRS was not considered to be the
primary beneficiary due to the fact that the power to direct the activities of the joint venture is shared among multiple unrelated parties such that no one party has the power to direct the activities of the joint venture that most significantly
impact the joint ventures economic performance. In connection with the Austin Portfolio Joint Venture, we determined the key activities that drive the economic performance of the joint venture to be (1) the acquisition and development of
real estate (including capital improvements), (2) financing, and (3) leasing. In connection with these key activities, the Austin Portfolio Joint Venture partnership agreement requires either unanimous or majority approval of decisions by
the respective partners. We therefore determined the power to direct the activities to be shared amongst the Partners so that no one Partner has the power to direct the activities that most significantly impact the partnerships economic
performance. As of September 30, 2010, our total maximum exposure to loss to TPG/CalSTRS and the Austin Portfolio Joint Venture is:



| | (1) | Our equity investment in the various properties controlled by TPG/CalSTRS and the Austin Portfolio Joint Venture as of September 30, 2010, which was $19.5 million,
as presented earlier in this note.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | The potential loss of future fee revenues which we earn in connection with the management and leasing agreements with the various properties controlled by the
respective joint ventures. We earn fee revenues in connection with those management and leasing agreements for services such as property management, leasing, asset management and property development. The management and leasing agreements with the
various properties generally expire on an annual basis and are automatically renewed for successive periods of one year each, unless we elect not to renew the agreements. As of September 30, 2010, we had total receivables of $1.3 million and
$0.7 million related to TPG/CalSTRS and the Austin Portfolio Joint Venture, respectively.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) | Unfunded capital commitments to the TPG/CalSTRS joint venture was $21.0 million as of September 30, 2010, which was subsequently reduced to $19.0 million.
There were no unfunded capital commitments to the Austin Portfolio Joint Venture as of September 30, 2010, however, TPG has committed to advance funds to the Austin Portfolio Joint Venture under a senior secured priority facility established
and funded on a pro rata basis by all of the Austin Portfolio Joint Venture partners, of which our unfunded share is $1.7 million. To date, approximately $33.0 million of the senior secured priority facility has been advanced by the partners, of
which the Company has advanced $2.1 million. The funds advanced under the senior secured priority facility are a first priority mortgage lien on three of the Austin buildings and a first priority right to payment on a pledge of the equity interests
in the other seven Austin buildings owned by the Austin Partnership.

On March 6, 2010, an aggregate of
$96.5 million in mortgage loans owed by subsidiaries of TPG/CalSTRS (the borrowers) on unconsolidated properties at Four Falls Corporate Center, Oak Hill Plaza, and Walnut Hill Plaza matured and became due in full. The borrowers under
these loans have not made payment on these loans and they are currently in default. These loans are non-recourse to the borrowers and the Company, both of which do not anticipate making any payments or equity contributions to support the repayment
or refinancing of these loans. The borrowers are currently in discussions with the lenders to restructure the debt or facilitate a sale or other liquidation of these properties. We do not believe that the loss of our equity interests in these
properties will have a material effect on our business or results of operations.

|(2) | The mortgage loan may be defeased, and beginning February 2012, may be prepaid.
|--- | -------------------------------------------------------------------------------



|(3) | The interest rate as of September 30, 2010 was 4.1% per annum. The loan is scheduled to mature on July 31, 2011 with three one-year extension options, at
our election, subject to us complying with certain covenants, with a final maturity date of July 31, 2014 if all extension options are exercised. The lender has the option to require a principal payment of $2.5 million at the time of each
extension. We have guaranteed 100% of the principal, interest and any other sum payable under this loan. We have agreed to certain financial covenants on this loan as the guarantor, which we were in compliance with as of September 30, 2010.

|(4) | The loan has an unfunded commitment of $9.4 million which is available to fund any remaining project costs. The interest rate as of September 30, 2010 was
3.8% per annum. The loan is scheduled to mature on July 31, 2012 with two one-year extension options at our election subject to certain conditions. We have provided a repayment and completion guaranty up to 46.5% of the balance of the
outstanding principal, interest and any other sum payable under this loan. We have also provided collateral of approximately 62.4 acres of fully entitled unimproved land, which is immediately adjacent to our Four Points Centre office buildings
located in Austin, Texas. We have also committed to pay down the principal amount of the loan by $1.3 million in December, 2010. We have agreed to certain financial covenants on this loan as the guarantor, which we were in compliance with as of
September 30, 2010. As of January 31, 2011, if the Four Points office buildings are not at least 65% leased on terms consistent with the appraisal pro forma, we must pre-fund 18 months of interest into a restricted cash account with the
lender; if the buildings are less than 35% leased at that time, we will also have to pay $2.0 million as a principal reduction of the loan.

|(5) | On July 26, 2010, the Company extended the Murano condominium construction loan with Corus Construction Venture, LLC, for one year to July 31, 2011, with the
right to two six-month extensions. The loan will bear interest at the greater of 9.5% or three month LIBOR plus 3.25%. Subsequent to September 30, 2010, we sold one additional unit, which, upon closing, will reduce the principal balance by
approximately $0.4 million.

5. Income (Loss) Per Share and Dividends Declared

In calculating basic and diluted earnings per share, the Company includes restricted stock and incentive units granted to employees as we
consider these share-based instruments to be participating securities because they have non-forfeitable rights to dividends.

Basic earnings per share is calculated based on dividends declared on common shares and other participating securities (distributed
earnings) and the rights of common shares and participating securities in any undistributed earnings, which represents net income remaining after deduction of dividends accruing during the respective period. The undistributed earnings are
allocated to all outstanding common shares and participating securities based on the relative percentage of each security to the total number of outstanding securities. Basic earnings per common share and participating security represent the
summation of the distributed and undistributed earnings per common share and participating security divided by the total weighted average number of common shares outstanding and the total weighted average number of participating securities
outstanding during the respective years. We only present the earnings per share attributable to the common shareholders.

For
the three and nine months ended September 30, 2009, the Company incurred losses and paid dividends. The net losses, after deducting the dividends to participating securities (restricted stock and incentive partnership units), are allocated in
full to the common shares since the participating security holders do not have an obligation to share in the losses, based on the contractual rights and obligations of the participating securities. In December 2009, our board of directors suspended
its quarterly dividends to common stockholders. Because we incurred losses for the three and nine months ended September 30, 2010 and 2009, all potentially dilutive instruments are anti-dilutive and have been excluded from our computation of
weighted average dilutive shares outstanding.

As of September 30, 2010, approximately 569,000 nonvested restricted stock units, 196,000 vested
incentive units and 90,000 nonvested incentive units were excluded from the calculation of diluted earnings per share because they were anti-dilutive due to our net loss position. As of September 30, 2009, 610,000 nonvested restricted stock
units, 234,000 incentive units and 278,000 nonvested incentive units were excluded from the calculation of diluted earnings per share because they were anti-dilutive due to our net loss position.

6. Equity

Common Stock and Operating
Partnership Units

The holders of common stock are entitled to one vote per share on all matters to be voted upon by the
stockholders. Holders of our common stock vote together as a single class with holders of our limited voting stock on those matters upon which the holders of limited voting stock are entitled to vote. Subject to preferences that may be applicable to
any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably any dividends when, if, and as may be declared by the board of directors out of funds legally available for dividend payments. A Unit and a share
of our common stock have essentially the same economic characteristics as they share equally in the total net income or loss and distributions of the Operating Partnership. A Unit may be redeemed by the holder in exchange for cash or shares of
common stock at our election, on a one-for-one basis. As of September 30, 2010 and December 31, 2009, we held a 71.6% and 68.8% interest in the Operating Partnership, respectively.

Issuances of Common Stock

On December 23, 2009, the Company completed
the sale of 5.1 million shares through a registered direct offering of common stock at $2.55 per share. The net proceeds after deducting offering expenses were $13.1 million. We used the net proceeds to fund a portion of the discounted payoff
of $25.2 million for the nonrecourse senior and junior mezzanine loans on Two Commerce Square, which had a balance of $36.6 million and were scheduled to mature in January 2010.

During the second quarter of 2010, we sold 4.2 million shares of common stock at prices ranging from $3.67 to $5.03 per share in our
at- the-market equity offering program. These sales resulted in net proceeds to the Company of $15.2 million, to be used for general corporate purposes.

Subsequent to September 30, 2010, we sold 48,500 shares of common stock at prices ranging from $3.77 to $3.80 per share in our at-the-market equity offering program. These sales resulted
in net proceeds to the Company of approximately $179,000, to be used for general corporate purposes.

Limited Voting Stock

Each operating partnership unit issued in connection with the formation of our operating partnership at the time of our initial public
offering in 2004 was paired with one share of limited voting stock. Operating partnership units issued under other circumstances, including upon the conversion of incentive units granted under the Incentive Plan, are not paired with shares of
limited voting stock. These shares of limited voting stock are not transferable separate from the limited partnership units they are paired with, and each operating partnership unit is redeemable together with one share of limited voting stock by
its holder for cash, or, at our election, one share of our common stock. Each share of limited voting stock entitles its holder to one vote on the election of directors, certain extraordinary transactions, including a merger or sale of our company,
and amendments to our certificate of incorporation. Shares of limited voting stock are not entitled to any regular or special dividend payments or other distributions, including any dividends or other distributions declared or paid with respect to
shares of our common stock or any other class or series of our stock, and are not entitled to receive any distributions in the event of liquidation or dissolution of our company.

Incentive Partnership Units

We have issued a total of 1,303,336 incentive units as of September 30, 2010 to certain employees. Incentive units
represent a profit interest in the Operating Partnership and generally will be treated as regular limited partnership units in the Operating Partnership and rank pari passu with the limited partnership units as to payment of distributions, including
distribution 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 limited partnership units, but only to the extent of the incentive units economic capital account balance. As of September 30, 2010, we had 35,394,894 shares of common
stock, 13,813,331 Operating Partnership units and 285,556 incentive units outstanding. The share of the Company owned by the Operating Partnership unit holders is reflected as a separate component called noncontrolling interests in the equity
section of our consolidated balance sheets.

Stock Compensation

We adopted the 2004 Equity Incentive Plan of Thomas Properties Group, Inc., as amended (the Incentive Plan), effective upon
the closing of our initial public offering and amended it in May 2007 and June 2008 to increase the shares reserved under the plan. The Incentive Plan provides incentives to our employees and is designed to attract, reward and retain personnel. Our
Incentive Plan permits the granting of awards in the form of options to purchase common stock, restricted shares of common stock and restricted incentive units in our Operating Partnership. We may issue up to 3,361,906 shares as either stock option
awards, restricted stock awards or incentive unit awards of which 580,714 remain available for grant as of September 30, 2010. Shares of newly issued common stock will be issued upon exercise of stock options. In addition, under our
Non-Employee Directors Restricted Stock Plan (the Non-Employee Directors Plan) a total of 60,000 shares are reserved for grant, of which 29,065 remain available for grant.

For more information on our stock incentive plan, please refer to the notes to the consolidated financial statements in our 2009 Annual
Report on Form 10-K, which was filed with the SEC on March 22, 2010, and our proxy statement, which was filed with the SEC on April 28, 2010.

During the first quarter of 2010, we granted 100,000 of restricted stock shares with a total fair market value of approximately $0.3 million. During the first quarter of 2009, we granted 410,000
restricted stock shares with a total fair market value of $0.5 million. Both the 2010 and 2009 grants are subject to vesting.

We recognized non-cash compensation expense and the related income tax benefit for the vesting of stock grants for the three and nine

Noncontrolling Interests

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

The Company periodically
evaluates individual noncontrolling interests for the ability to continue to recognize the noncontrolling interest as permanent equity in the consolidated balance sheets. Any noncontrolling interest that fails to qualify as permanent equity will be
reclassified as temporary equity and adjusted to the greater of (a) the carrying amount, or (b) its redemption value as of the end of the period in which the determination is made.

The redemption value
of the 285,556 outstanding incentive units not owned by the Company at September 30, 2010 was approximately $1,019,000 based on the closing price of the Companys common stock of $3.57 per share as of September 30, 2010.

A charge is recorded each period to the consolidated statements of income (loss) for the noncontrolling interests proportionate
share of the Companys net income (loss).

Equity is allocated between controlling and noncontrolling interests as

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. However, the Operating Partnership and some of its subsidiaries are subject to income taxes in the state of Texas. 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 limited partnership agreement. As of September 30, 2010, we held a 71.6% capital interest in the Operating Partnership. For the three and nine months ended September 30,
2010, we were allocated a weighted average of 70.9% of the income and losses from the Operating Partnership.

Our effective
tax rate for the three and nine months ended September 30, 2010, was (3.4)% and (6.1)%, respectively, compared to the federal statutory rate of 35%. The difference from the statutory rate is due primarily to income attributable to the
noncontrolling interests, and the valuation allowance related to the Companys deferred tax assets for which no benefit could be provided due to the realization not meeting the more-likely-than-not threshold.

A net deferred tax asset is included in other assets on the Companys balance sheet. The Companys existing federal
and state net operating loss carryforwards, which existed as of a deemed ownership change in 2007 is subject to the gross annual limitation under Internal Revenue Code Section 382 (Section 382), which is $9.9 million per year. The
net operating loss carryforwards generated subsequent to the 2007 ownership change are not subject to the Section 382 limitation. As of the year ended December 31, 2009, the Company had net operating loss carryforwards of $31.6 million for
federal purposes and $23.9 million for state purposes. The Companys net operating loss carryforwards are subject to varying expirations from 2015 through 2029.

FASB ASC 740-10-30-17 Accounting for Income Taxes, 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. Future realization of the deferred tax asset is dependent on the reversal of existing taxable temporary differences, carryback potential, tax-planning strategies and on us generating sufficient taxable income in future
years as the deferred income tax charges become currently deductible for tax reporting purposes. We have recorded a valuation allowance on the net deferred tax assets in excess of their liability for unrecognized tax benefits discussed below, due to
uncertainty of future realization.

FASB ASC 740-10-15, clarifies the accounting for uncertainty in income taxes recognized in
a companys financial statements. 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 Companys policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense, which for the three and nine months ended September 30, 2010 was $146,000 and $469,000. We have not
recorded any penalties with respect to unrecognized tax benefits. For the nine months ended September 30, 2010, the Company has recorded a decrease of $3.9 million to our unrecognized tax benefits. We do not anticipate any significant increases
or decreases to the remaining amounts of the existing unrecognized tax benefits within the next twelve months.

8. Fair Value of Financial
Instruments

FASB ASC 825-10-50-8, Financial Instruments, requires us to disclose fair value information about
all financial instruments, whether or not recognized in the balance sheets, for which it is practicable to estimate fair value. Our estimates of the fair value of financial instruments as of September 30, 2010 were determined using available
market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation methods may have a material effect on the
estimated fair value amounts. The carrying amounts for cash and cash equivalents, restricted cash, rent and other receivables, accounts payable and other liabilities approximate fair value due to the short-term nature of these instruments. As of
September 30, 2010, the fair value of our consolidated mortgage and other secured loans aggregates $281.1 million, compared to the aggregate carrying value of $301.96 million on our consolidated balance sheet.

9. Subsequent Events

During October 2010, we sold 48,500 shares of common stock at prices ranging from $3.77 to $3.80 per share in our
at-the-market equity offering program. These sales resulted in net proceeds to the Company of approximately $179,000, to be used for general corporate purposes.

On October 12, 2010, TPG/CalSTRS closed a new non-recourse first mortgage loan for CityWestPlace Buildings III and IV, two buildings located in Houston, Texas. The new mortgage loan in the amount of
$95 million was provided by The Northwestern Mutual Life Insurance Company. The loan bears interest at a fixed rate of 5.03% and will mature in March 2020. It replaces a floating rate loan in the amount of $92.4 million, which was scheduled to
mature in July 2011.

On October 19, 2010, TPG/CalSTRS restructured the debt and equity capital in our Centerpointe
partnership by acquiring the mezzanine A and B notes for approximately $40 million, at a discount to par of approximately $6.6 million or 14%. In addition, the mezzanine C loan was modified to provide us with the right to prepay the loan equal to a
50% discount on the principal plus a participation feature for the lender. The mezzanine C loan was also extended through February 9, 2012 with one additional year of extension available up to February 9, 2013. CalSTRS contributed 95% and
TPG contributed 5% of the $40 million, which will be treated as preferred equity.

During the third quarter, TPG and
Brandywine Realty Trust (BDN) entered into contribution agreements whereby BDN agreed to invest in partnerships with TPG that own Commerce Square, which have been heretofore wholly-owned by TPG. BDN will contribute a total of $25 million
of preferred equity to the partnerships, and will become a 25% limited partner. The transaction closed on November 10, 2010, and BDNs preferred equity of $5 million was contributed at closing with the balance to be contributed by
December 31, 2012. The preferred equity will be invested in a value-enhancement program designed to increase rental rates and occupancy at Commerce Square.

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

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

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

Forward-Looking Statements

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

Overview and Background

We are a full-service real estate operating company that owns, acquires, develops and manages primarily office, as well as mixed-use and

Comparison of three months ended September 30, 2010 to three months ended September 30, 2009

Total revenues. Total revenues decreased by $17.8 million, or 41.5%, to $25.1 million for the three months ended September 30,
2010 compared to $42.9 million for the three months ended September 30, 2009. The significant components of revenue are discussed below.

Rental revenues.Rental revenue remained consistent for each of the three month periods ended September 30, 2010 and 2009.

Tenant reimbursements.Tenant reimbursements increased by $0.4 million, or 8.7%, to $5.0 million for the three months ended
September 30, 2010 compared to $4.6 million for the three months ended September 30, 2009. The increase was primarily due to higher recoverable operating expenses in 2010 as compared to 2009.

Parking and other revenues.Parking and other revenues increased by $0.3 million or 50.0%, to $0.9 million for the three months
ended September 30, 2010 compared to $0.6 million for the three months ended September 30, 2009. The increase was primarily related to lease termination fees recognized at One Commerce Square, which are classified as other revenues.

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 $1.0 million, or 38.5%, from $2.6 million for the three months ended September 30, 2009 to $1.6 million for the
three months ended September 30, 2010. The decrease was primarily due to lower leasing activity in addition to decreased construction management activity.

Investment advisory, management, leasing and development services revenues  unconsolidated real estate entities.This caption represents revenues earned from services provided to entities for
which we use the equity method to account for our ownership interest. Revenues from these services from unconsolidated real estate entities increased $0.3 million or 8.8%, from $3.4 million for the three months ended September 30, 2009 to $3.7
million for the three months ended September 30, 2010 primarily due to higher management and advisor fees in connection with our decreased ownership interest in City National Plaza. Because we eliminate fee revenue paid to us equal to our
ownership share, the amount of eliminated revenue related to City National Plaza has decreased with the corresponding decrease in our ownership share.

Reimbursement of
property personnel costs.This caption represents the reimbursement for property personnel salary, payroll taxes and benefits. Reimbursements remained consistent for each of the three month periods ended September 30, 2010 and 2009.

Condominium sales.This caption represents revenue recognized for the Murano condominium units and parking spaces
which closed during the three months ended September 30, 2010. Sales decreased by $17.7 million, or 77.3%, to $5.2 million for the three months ended September 30, 2010, compared to $22.9 million for the three months ended
September 30, 2009 as a result of closing nine units this quarter as compared to 56 units during the corresponding quarter of 2009.

Total expenses.Total expenses decreased by $27.8 million, or 50.3%, to $27.5 million for the three months ended September 30, 2010, compared to $55.3 million for the three months ended
September 30, 2009. The significant components of expense are discussed below.

Property operating and maintenance
expense.Property operating and maintenance expenses remained consistent for each of the three month periods ended September 30, 2010 and 2009.

Real estate taxes. Real estate taxes decreased by $0.2 million, or 10.5%, to $1.7 million for the three months ended September 30, 2010, compared to $1.9 million for the three months ended
September 30, 2009, primarily due to a tax adjustment of $0.3 million occurring in 2009 as a result of an increase in property assessed value in connection with the completion of construction of two office buildings at our Four Points
development site.

Investment advisory, management, leasing and development services expenses.Expenses for these
services increased by $0.2 million, or 7.1%, to $3.0 million for the three months ended September 30, 2010, compared to $2.8 million for the three months ended September 30, 2009, primarily due to an increase in professional fees partially
offset by a decrease in employee compensation.

Reimbursable property personnel costs. This caption represents the
reimbursement of property personnel salary, payroll taxes and benefits. Reimbursable personnel costs remained consistent for each of the three month periods ended September 30, 2010 and 2009.

Cost of condominium sales.The decrease of $17.0 million, or 81.3% to $3.9 million for the three months ended September 30,
2010 compared to $20.9 million for the three months ended September 30, 2009 is due to the settlement of nine units at the Murano as compared to 56 in the corresponding three month period ending September 30, 2009.

Interest expense.Interest expense decreased by $2.0 million, or 29.4%, to $4.8 million for the three month period ended
September 30, 2010 from $6.8 million for the three month period ended September 30, 2009. The decrease in interest expense is primarily attributable to the payoff of mezzanine debt at Two Commerce Square in December 2009, which resulted in
a decrease of $1.7 million compared to the prior period. Also, interest incurred on our Murano loan decreased by $0.5 million as compared to the prior period due to a reduced principal balance, which is amortized with proceeds from each unit
sale.

Depreciation and amortization expense.Depreciation and amortization increased $0.4 million, or 13.3%, to $3.4
million for the three months ended September 30, 2010 compared to $3.0 million for the three months ended September 30, 2009. This increase was primarily attributable to assets associated with our Four Points office buildings, which were
placed in service in 2010.

General and administrative.General and administrative expense decreased by $0.5
million, or 12.8%, to $3.4 million for the three months ended September 30, 2010 compared to $3.9 million for the three months ended September 30, 2009. This was primarily due to a reduction in compensation expense of $0.7 million as a
result of cost saving measures, partially offset by an increase in professional fees.

Impairment loss. For the
three months ended September 30, 2009, we recognized a non-cash impairment charge of $8.6 million related to our Murano condominium project whose units are held for sale. The charge was recorded to reflect the units at their estimated fair
value. There was no corresponding impairment charge for the three months ended September 30, 2010.

Aggregate revenues for the three months ended September 30, 2010 increased approximately $0.4 million,
or 0.5%, to $79.8 million compared to $79.4 million for the three months ended September 30, 2009. The increase is primarily due to increased tenant reimbursement revenue. Aggregate operating and other expenses for unconsolidated real estate
entities for the three months ended September 30, 2010 increased approximately $1.2 million, or 2.9%, to $42.0 million compared to $40.8 million for the three months ended September 30, 2009 primarily due to increased utility expenses and
lower real estate taxes included in the three months ended September 30, 2009. Interest expense increased approximately $3.2 million, or 12.8%, to $28.2 million for the three months ended September 30, 2010 compared to $25.0 million for
the three months ended September 30, 2009. The increase was primarily the result of interest accrued at the default rate for Four Falls, Oak Hill and Walnut Hill whose loans are in a maturity default, as well as the refinance of City National
Plaza during the three months ended September 30, 2010. Depreciation and amortization expense decreased approximately $1.3 million, or 4.4%, to $28.0 million for the three months ended September 30, 2010 compared to $29.3 million for the
three months ended September 30, 2009. The decrease was primarily due to the early write-offs of lease-related assets in 2009 due to tenant defaults and early lease terminations coupled with reduced capital spending in 2010. For the three
months ended September 30, 2009, we recognized an $8.0 million impairment loss related to our Four Falls and Walnut Hill properties. There was no corresponding impairment loss in 2010. Gain on extinguishment of debt increased $5.2 million
during the three months ended September 30, 2010 compared to no gain during the three months ended September 30, 2009. The increase was due to the refinancing of the debt at City National Plaza, 2500 City West and San Felipe Plaza.

Provision for income taxes.Provision for income taxes decreased by $0.1 million to a provision of $0.1 million for
the three months ended September 30, 2010 compared to a provision of $0.2 million for the three months ended September 30, 2009. The decrease was primarily due to the Company reconciling the provision upon completion and filing of the
2009 tax returns.

Comparison of nine months ended September 30, 2010 to nine months ended September 30, 2009

Total revenues. Total revenues decreased by $10.9 million, or 12.6%, to $75.4 million for the nine months ended September 30,
2010 compared to $86.3 million for the nine months ended September 30, 2009. The significant components of revenue are discussed below.

Rental revenues.Rental revenue decreased by $0.7 million, or 3.1%, to $21.8 million for the nine month period ended September 30, 2010 compared to $22.5 million for the nine month period
ended September 30, 2009. The decrease was primarily related to a scheduled lease expiration in June of 2009 of a significant tenant at Two Commerce Square representing approximately 375,000 rentable square feet, offset by revenues from former
subtenants or new tenants that are now direct tenants.

Tenant
reimbursements.Tenant reimbursements decreased by $0.7 million, or 4.3%, to $15.5 million for the nine months ended September 30, 2010 compared to $16.2 million for the nine months ended September 30, 2009. The decrease was primarily
related to a scheduled lease expiration in June 2009 of a significant tenant at Two Commerce Square representing approximately 375,000 rentable square feet, offset by a decrease in refunds to tenants in 2010 as compared to 2009 related to their
share of operating expenses and by revenues from former subtenants or new tenants that are now direct tenants.

Parking and
other revenues.Parking and other revenues increased by $0.5 million, or 22.7%, to $2.7 million for the nine months ended September 30, 2010 from $2.2 million for the nine months ended September 30, 2009. The increase was primarily
related to lease termination fees recognized at One Commerce Square, which are classified as other revenues.

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 $1.6
million, or 22.2%, from $7.2 million for the nine months ended September 30, 2009, to $5.6 million for the nine months ended September 30, 2010 primarily due to less leasing activity resulting in lower commissions of $1.5 million relative
to the prior period, partially offset by an increase in development fees related to our Wilshire Grand project with Korean Airlines, which we began earning in April of 2009.

Investment advisory, management, leasing and development services revenues  unconsolidated real estate entities.This caption represents revenues earned from services provided to entities for
which we use the equity method to account for our ownership interest. Revenues from these services remained consistent for each of the nine month periods ended September 30, 2010 and 2009.

Reimbursement of property personnel costs.This caption represents the reimbursement for property personnel salary, payroll taxes
and benefits. Reimbursements revenue was consistent for each of the nine month periods ended September 30, 2010 and 2009.

Condominium sales.The decrease of $8.3 million, or 36.2%, to $14.6 million for the nine months ended September 30, 2010
compared to $22.9 million for the nine months ended September 30, 2009 is due to the settlement of 28 units as compared to 60 units for the corresponding period in 2009.

Total expenses.Total expenses decreased by $26.9 million, or 24.8%, to $81.4 million for the nine months ended September 30, 2010 compared to $108.3 million for the nine months ended
September 30, 2009. The significant components of expense are discussed below.

Property operating and maintenance
expense.Property operating and maintenance expenses increased by $0.3 million, or 1.6% to $18.7 million for the nine months ended September 30, 2010 compared to $18.4 million for the nine months ended September 30, 2009. The increase
was primarily attributable to an increase in contract cleaning expenses.

Real estate taxes.Expenses for taxes
decreased by $0.2 million, or 3.7%, to $5.2 million for the nine months ended September 30, 2010, compared to $5.4 million for the nine months ended September 30, 2009, primarily due to 2009 special taxes associated with the Murano
recorded in 2009 with no comparable expense recorded in 2010.

Investment advisory, management, leasing and development
services expenses. Expenses for these services decreased by $0.6 million, or 7.0%, to $8.0 million for the nine months ended September 30, 2010, compared to $8.6 million for the nine months ended September 30, 2009, primarily due to
employee compensation reductions related to cost saving measures.

Reimbursable property personnel costs.This caption
represents the reimbursement of property personnel salary, payroll taxes and benefits. Reimbursable expenses remained consistent for each of the nine month periods ended September 30, 2010 and 2009.

Cost of condominium sales.The decrease of $10.2 million or 48.8%, to $10.7 million for the nine months ended September 30,
2010 compared to $20.9 million for the nine months ended September 30, 2009 is due to the settlement of 28 units at the Murano as compared to 60 units in the corresponding period in 2009.

Interest expense.Interest expense decreased by $6.0 million, or 29.4%, to $14.4 million for the nine month period ended
September 30, 2010 from $20.4 million for the nine month period ended September 30, 2009. The decrease in interest expense is primarily attributable to the payoff of mezzanine debt at Two Commerce Square in December 2009, which resulted in
a decrease of $5.1 million compared to the prior period. Also, interest incurred on our Murano loan decreased by $1.6 million as compared to the prior period due to a reduced principal balance, which is amortized with proceeds from each unit sale.

Depreciation and amortization expense.Depreciation and amortization increased $1.0 million, or 10.6%, to $10.4
million for the nine months ended September 30, 2010 compared to $9.4 million for the nine months ended September 30, 2009. This increase was primarily attributable to assets associated with our Four Points office buildings, which were
placed in service in 2010.

General and
administrative.General and administrative expense decreased by $2.4 million, or 19.5%, to $9.9 million for the nine months ended September 30, 2010 compared to $12.3 million for the nine months ended September 30, 2009. This was
primarily due to a reduction in compensation expense as a result of cost saving measures.

Impairment loss. For
the nine months ended September 30, 2009, we recognized a non-cash impairment charge of $8.6 million related to our Murano condominium project whose units are held for sale. The charge was recorded to reflect the units at their estimated fair
value. There was no corresponding impairment charge for the nine months ended September 30, 2010.

Interest Income.Interest income decreased by $0.2 million, or 66.7%, to $0.1 million, for the nine months ended September 30, 2010 compared to $0.3 million for the nine months ended September 30, 2009. The decrease was primarily attributable to lower
average cash balances combined with a decrease in interest rates earned.

Aggregate revenues for the nine months ended September 30, 2010 decreased approximately $5.5 million or
2.3% to $238.1 million compared to $243.6 million for the nine months ended September 30, 2009. The decrease is primarily due to lower occupancy at our Austin Portfolio Joint Venture downtown properties. Aggregate operating and other expenses
for unconsolidated real estate entities for the nine months ended September 30, 2010 increased approximately $0.7 million or 0.6% to $123.2 million compared to $122.5 million for the nine months ended September 30, 2009 primarily due to an
increase in insurance expense. Interest expense increased approximately $2.0 million or 2.6% to $79.9 million for the nine months ended September 30, 2010 compared to $77.9 million for the nine months ended September 30, 2009. The increase
was primarily due to the interest accrued at the default rate for Four Falls, Oak Hill and Walnut Hill whose loans are in a maturity default, as well as the refinance of City National Plaza, partially offset by the write-off of deferred financing
costs associated with the Austin Portfolio Joint Venture debt restructure in March 2009. Depreciation and amortization expense decreased approximately $4.9 million or 5.4%, to $85.8 million for the nine months ended September 30, 2010 compared
to $90.7 million for the nine months ended September 30, 2009. The decrease was primarily due to the early write-offs of lease-related assets during 2009 due to tenant defaults and early lease terminations, coupled with reduced capital spending
in 2010. For the nine months ended September 30, 2009, we recognized an $8.0 million impairment loss related to our Four Falls and Walnut Hill properties. There was no corresponding impairment in 2010. A gain of $67.0 million on early
extinguishment of debt recorded for the nine months ended September 30, 2009 was related to our Austin Portfolio Joint Venture debt restructure and recapitalization. We recorded similar gains in connection with the refinancing of the debt for
City National Plaza, 2500 City West and San Felipe Plaza during the nine months ended September 30, 2010.

Gain on early
extinguishment of debt. In October 2005, we purchased the entire interest of our unaffiliated partner in the venture which owns our Campus El Segundo development project, of which $3.9 million was financed with an unsecured loan from the former
partner. Principal and accrued interest on this loan had a scheduled maturity of October 12, 2009. The final installment of principal and interest was paid early on April 3, 2009, and therefore, we recognized a gain on early extinguishment
of debt of $0.5 million related to this loan in the nine months ended September 30, 2009. There was no corresponding gain recognized in the nine months ended September 30, 2010.

Provision for income taxes. Provision for income taxes of $0.4 million for the nine months ended September 30, 2010 is
consistent with the provision for income taxes recorded for the nine months ended September 30, 2009 of $0.5 million.

Liquidity and
Capital Resources

Analysis of liquidity and capital resources

As of September 30, 2010, we have unrestricted cash and cash equivalents of $43.2 million. We believe that we will have sufficient
capital to satisfy our liquidity needs over the next 12 months through working capital. We expect to meet our long-term liquidity requirements, including debt service, property 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 additional debt, or common or preferred equity securities, including convertible
securities. Additionally, as noted elsewhere herein, on December 23, 2009, the Company completed the sale of 5.1 million shares through a registered direct offering of common stock at $2.55 per share. The net proceeds after deducting
offering expenses were $13.1 million. We used the net proceeds to fund a portion of the discounted payoff of $25.2 million for the nonrecourse senior and junior mezzanine loans on Two Commerce Square, which had a balance of $36.6 million and were
scheduled to mature in January 2010. During the second quarter of 2010, we sold 4.2 million shares of common stock at prices ranging from $3.67 to $5.03 per share in our at-the-market equity offering program. These sales resulted in
net proceeds of $15.2 million, which are being used for general corporate purposes. Subsequent to the third quarter, we sold 48,500 shares of common stock at prices ranging from $3.77 to $3.80 per share in our at-the-market equity
offering program. These sales resulted in net proceeds to the Company of approximately $179,000, to be used for general corporate purposes.

Assuming the exercise of extension options available to us, there is no debt maturing in our portfolio until 2012. With respect to debt maturing in 2012 and thereafter, we will seek to refinance this debt
at maturity or retire it through the issuance of securities, as market conditions permit. There can be no assurances that such debt refinancing will be available at the time of such maturities on acceptable terms, if at all, and our cost of capital
could increase as a result of any such debt refinancing. If we are unable to obtain debt refinancing for properties in which we own an interest at maturity, we may lose some or all of our equity interests in such properties. Additionally, existing
stockholders could experience substantial dilution in the event we are required to issue additional equity capital.

As
indicated in the Contractual Obligations table on page 30, we have $1.43 million of scheduled principal payments on consolidated debt remaining in 2010 and $1.97 million in 2011. We believe that we have sufficient capital to satisfy these payments.
Refer to this table and the corresponding notes for further detail. With respect to the debt owed by our unconsolidated real estate entities, the table beginning on page 32 and the notes thereto indicate that there are no remaining maturity dates in
2010 and no additional principal payments due in 2010. Subsequent to September 30, 2010, we refinanced the mortgage loan on our CityWestPlace property Buildings III and IV resulting in no remaining maturity dates in 2011 and no additional
principal payments due in 2011.

On March 6, 2010, an aggregate of $96.5 million in mortgage loans owed by subsidiaries
of TPG/CalSTRS (the borrowers) on unconsolidated properties at Four Falls Corporate Center, Oak Hill Plaza and Walnut Hill Plaza matured and became due in full. The borrowers under these loans have not made payment on these loans and
they are currently in default. These loans are non-recourse to the borrowers and the Company, both of which do not anticipate making any payments or equity contributions to support the repayment or refinancing of these loans. The borrowers are
currently in discussions with the lenders to restructure the debt or facilitate a sale or other liquidation of these properties. We do not believe that the loss of our equity interests in these properties will have a material effect on our business
or results of operations.

As of September 30, 2010, we have unfunded capital commitments to (1) our joint venture
with CalSTRS of $21.0 million (subsequently reduced to $19.0 million); and (2) the Thomas High Performance Green Fund (the Green Fund), an investment fund formed by us, CalSTRS and other institutional investors, of $50.0 million.
With respect to our joint venture with CalSTRS, we are not obligated to fund our share of the capital commitment for the acquisition of any new project, but we are obligated to fund tenant improvements and other capital improvements for projects
that were acquired prior to June 1, 2007. We estimate we will fund $3.6 million in 2010 and $1.3 million in 2011 to cover our share of contractual obligations existing at September 30, 2010, for capital improvements, tenant improvements
and leasing commissions. Our requirement to fund all or a portion of our commitments to the Green Fund is subject to our identifying properties to acquire at our discretion. Our cash requirements for the Green Fund could be reduced by contributions
by us to the fund of assets in which we have an interest. The Green Funds investment period is scheduled to expire on December 31, 2010.

In December 2009, our
board of directors suspended its quarterly dividends to common stockholders. The availability of funds to pay dividends is impacted by property-level restrictions on cash flows. With respect to our joint venture properties, we do not solely control
decision making with respect to these properties, and may not be able to obtain monies from these properties even if funds are available for distribution to us. In addition, we may enter future financing arrangements that contain restrictions on our
use of cash generated from our properties. The payment of cash dividends in the future, if any, will be at the discretion of our board of directors and will depend upon such factors as earnings levels, capital requirements, our overall financial
condition, and any other factors deemed relevant by our board of directors.

Development and Redevelopment Projects

We own interests in four development projects, and our joint venture with CalSTRS includes four redevelopment properties and two
development sites.

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

We have completed construction of the Murano, a 302-unit high-rise residential condominium project in downtown Philadelphia. We have closed sales on 219 units as of September 30, 2010. During the
three months ended September 30, 2010, we contracted for the sale of five units and closed on the sale of nine units resulting in a gain on sale of approximately $1.4 million. Murano is classified as condominium units held for sale on our
balance sheet.

The amount and timing of costs associated with our development and redevelopment projects is inherently
uncertain due to market and economic conditions. We presently intend to fund development and redevelopment expenditures primarily through construction or refurbishment financing.



| |  |  | Construction of the Murano was financed in part with a construction loan up to $142.5 million. Repayment of this loan is being made with proceeds from
the sales of condominium units. The loan has a balance of $22.6 million as of September 30, 2010. Subsequent to September 30, 2010, we sold one additional unit, which, upon closing, will reduce the principal balance by approximately $0.4
million. On July 26, 2010, the Company extended the Murano construction loan with Corus Construction Venture, LLC, for one year to July 31, 2011, with the right to two six-month extensions. The loan will bear interest at the greater of
9.5% or three month LIBOR plus 3.25%. We have no guarantees on this debt other than the payment of interest through the maturity date.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The completed core and shell construction of two office buildings at our development site at Four Points Centre was financed in part with a
construction loan, which has an outstanding balance as of September 30, 2010 of $24.6 million with additional borrowing capacity of $9.4 million to fund tenant improvements and other project costs. The Four Points Centre construction loan has a
maturity date of July 31, 2012 with two one-year extension options subject to certain conditions. We have committed to pay down the principal amount of the loan by $1.3 million in December 2010. The interest rate on the loan is LIBOR plus
3.5% per annum. Additionally, we have guaranteed 46.5% of the balance of the outstanding principal, interest and any other sum payable under this loan, which after the $1.3 million principal payment results in a maximum guarantee amount of
$10.8 million. We also provided collateral of approximately 62.4 acres of fully entitled unimproved land, which is immediately adjacent to our Four Points Centre office buildings. As of January 31, 2011, if the Four Points office buildings are
not at least 65% leased on terms consistent with the appraisal pro forma, we must pre-fund 18 months of interest into a restricted cash account with the lender; if the buildings are less than 35% leased at that time, we will also have to pay $2.0
million as a principal reduction of the loan.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Presently, we have not obtained construction financing for the development at Campus El Segundo.
| | - |  | ------------------------------------------------------------------------------------------------

If we finance development projects through construction loans and are unable to obtain permanent financing on advantageous terms or at
all, we would need to fund these obligations from cash flow from operations or seek alternative capital sources. If unsuccessful, this could adversely impact our financial condition and results of operations and impair our ability to satisfy our
debt service obligations. If we are successful in obtaining construction or refurbishment financing and permanent financing, we anticipate that the corresponding interest costs would represent both a significant use of our cash flow and a material
component of our results of operations.

We are also involved
in managing the following three entitlement projects:



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



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



| |  |  | Korean Air, a subsidiary of Hanjin Group, has retained us as fee developer for the entitlement, design and redevelopment of the 2.7 acre Wilshire Grand
property in downtown Los Angeles. The Wilshire Grand project envisions the development of two buildings, one approximately 65 stories and the other approximately 45 stories, to include approximately 1.5 million square feet of office, 560
hotel rooms, and up to 100 residential condominiums, with supporting retail and restaurant uses, for a total project size of up to approximately 2.5 million gross square feet.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Leasing, Tenant Improvement and Capital Needs

In addition to our development and redevelopment projects, our One Commerce Square and Two Commerce Square properties require capital maintenance and expenditures for leasing commissions and tenant
improvement costs. The level of these expenditures varies from year to year based on several factors, including lease expirations. We are contractually committed to incur expenditures of approximately $6.2 million in capital improvements, tenant
improvements, and leasing commissions for the One Commerce Square and Two Commerce Square properties, collectively, during 2010 through 2013. Additionally, we expect to expend additional amounts in connection with a value-enhancement program at
Commerce Square. The funding for both the $6.2 million of existing commitments and future expenditures under the value-enhancement program are discussed in the paragraph below.

During the third quarter, TPG and Brandywine Realty Trust ("BDN") entered into contribution agreements whereby BDN agreed to invest in
partnerships with TPG that own Commerce Square, which have been heretofore wholly-owned by TPG. BDN will contribute a total of $25 million of preferred equity to the partnerships, and will become a 25% limited partner. The transaction closed on
November 10, 2010, and BDNs preferred equity of $5 million was contributed at closing with the balance to be contributed by December 31, 2012. The preferred equity will be invested in a value-enhancement program designed to increase
rental rates and occupancy at Commerce Square.

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.

July 31, 2012 with two one-year extension options subject to certain conditions. We have provided a guarantee for a portion of principal and interest payable. We have also provided collateral of approximately 62.4 acres of fully entitled
unimproved land, which is immediately adjacent to our Four Points Centre office buildings. We have committed to pay down the principal amount of the loan by $1.3 million in December, 2010. The loan has an unfunded balance of $9.4 million which is
available to fund any remaining project costs. The interest rate on the loan is LIBOR plus 3.50% per annum. The balance of the loan as of September 30, 2010 was $24.6 million.

|(2) | The Murano construction loan has a balance of $22.6 million as of September 30, 2010. On July 26, 2010, the Company extended the loan with Corus Construction
Venture, LLC, for one year to July 31, 2011, with the right to two six-month extensions. The loan will bear interest at the greater of 9.5% or three month LIBOR plus 3.25%. This loan is nonrecourse to the Company, but the Company guarantees the
payment of interest during the term of the loan. We amortize the principal balance of the loan with approximately 93% of the sales proceeds as we close on the sale of condominium units. Subsequent to September 30, 2010, we sold one additional
unit, which, upon closing, will reduce the principal balance by approximately $0.4 million.

|(3) | As of September 30, 2010, 78.7% of our debt was at contractually fixed rates. The information in the table above reflects our projected interest obligations for
the fixed-rate payments based on the contractual interest rates and scheduled maturity dates. The remaining 21.3% of our debt bears interest at variable rates based on LIBOR plus a spread that ranges from 3.25% to 3.75%. The interest payments on the
variable rate debt have not been reported in the table above because we cannot reasonably determine the future interest obligations on our variable rate debt as we cannot predict what LIBOR rates will be in the future. As of September 30, 2010,
one-month LIBOR was 0.26%.

|(4) | Capital commitments of our company and consolidated subsidiaries include approximately $6.2 million of tenant improvements and leasing commissions for certain tenants
in One Commerce Square and Two Commerce Square. We have an unfunded capital commitment of $21.0 million to our TPG/CalSTRS joint venture, of which we estimate we will fund $3.6 million in 2010 for contractual obligations existing as of
September 30, 2010. We are not obligated to fund our share for the acquisition of any new project, but we are obligated to fund tenant improvements and other capital improvements for projects that were acquired prior to June 1, 2007.

|(6) | The obligations associated with uncertain tax provisions in the table above should represent amounts associated with uncertain tax positions related to temporary
book-tax differences. However, reasonable estimates cannot be made about the amount and timing of payment, if any, for these obligations. As of September 30, 2010, $16.4 million of unrecognized tax benefits have been recorded as liabilities on
our consolidated balance sheet, and we are uncertain as to if and when such amounts may be settled. Included within the unrecognized tax benefits is $2.6 million of accrued interest. We have not recorded any penalties with respect to
unrecognized tax benefits.

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

As of September 30, 2010, our company had investments in entities owning unconsolidated properties with stated
ownership percentages ranging from 6.25% to 50.0%. We account for these investments using the equity method of accounting. The table below summarizes the outstanding debt for these properties as of September 30, 2010 (in thousands). For loans
which had maturity dates extended subsequent to September 30, 2010, the new maturity date is not reflected in the Maturity Date column, but is described in the notes thereto. None of these loans are recourse to us other than as noted in
footnote 7 below. Some of the loans listed in the table below subject TPG/CalSTRS to customary non-recourse carve out obligations.

2010, a subsidiary of TPG/CalSTRS that owns CNP entered into a new non-recourse first mortgage loan in the amount of $350.0 million. The loan bears interest at a fixed rate of 5.9% and is for a term of ten years, to mature on July 1, 2020.

|(5) | On July 21, 2010, a subsidiary of TPG/CalSTRS that owns 2500 City West entered into a new mortgage loan in the amount of $65.0 million. The loan bears interest at
a fixed rate of 5.5% and is for a term of 9.3 years, to mature in December 2019. This mortgage loan replaces the prior $84.1 million mortgage loans, which were retired for $81.0 million pursuant to a discounted payoff agreement.

|(6) | On July 21, 2010, a subsidiary of TPG/CalSTRS that owns Brookhollow Central entered into a new mortgage loan in the amount of $55.0 million. At closing, $37.0
million of the loan was funded, with an additional $3.0 million to be funded over three years and $15.0 million available for future funding of construction costs related to the redevelopment of Brookhollow Central I. The loan bears interest at
LIBOR plus 2.6% and is for a three-year term plus two one-year extensions, subject to certain conditions, to mature upon final extension in July 2015. The new mortgage loan replaces the prior loans of $48.9 million.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(7) | The 2121 Market Street mortgage loan is prepayable without penalty after May 1, 2013, at which date the outstanding principal amount of this loan will be
approximately $17.2 million. The interest rate will increase to the greater of 8.1% or the treasury rate plus 2.0% on August 1, 2013. Any amounts over the initial interest rate may be deferred to the extent excess cash is not available to make
such payments. Provided there is no deferred interest, the loan balance will be fully amortized on August 1, 2033, the maturity date of the loan. The loan is guaranteed by our Operating Partnership and our co-general partner in the partnership
that owns 2121 Market Street, up to a maximum amount of $3.3 million.

|(8) | On October 19, 2010, TPG/CalSTRS restructured the debt and equity capital in our Centerpointe partnership by acquiring the mezzanine A and B notes for
approximately $40 million, at a discount to par of approximately $6.6 million or 14%. In addition, the mezzanine C loan was modified to provide us with the right to prepay the loan equal to a 50% discount on the principal plus a participation
feature for the lender. The mezzanine C loan was also extended through February 9, 2012 with one additional year of extension available up to February 9, 2013. CalSTRS contributed 95% and TPG contributed 5% of the $40 million, which will
be treated as preferred equity.

|(9) | These loans have a one-year extension option at our election.
|--- | -------------------------------------------------------------



|(10) | The margin above LIBOR on the bank term loan is subject to adjustment under certain circumstances. The term loan is secured by mortgages on three of the Austin
Portfolio Joint Venture properties and a pledge of equity interests in the remaining seven Austin Portfolio Joint Venture properties. These mortgage liens and equity pledges also secure the Austin senior secured priority facility, which has a
priority right to repayment ahead of the Austin Portfolio Bank Term Loan.
|---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(11) | During 2009, the Austin Portfolio Joint Venture entered into agreements pursuant to which (i) an existing $100 million revolving loan was terminated, (ii) a
senior secured priority facility of $60 million was established which a subsidiary of TPG/CalSTRS agreed to fund 25% on a pari passu basis with the partners in the Austin Portfolio Joint Venture, and (iii) the venture purchased and retired
$80 million of the Austin Portfolio bank term loan at a discount to face value, reducing that loan from $192.5 million to $112.5 million. The new $60 million Austin senior secured priority facility, which has a priority right to repayment ahead of
the Austin Portfolio Bank Term Loan, is senior in payment and right to the collateral to the Austin Portfolio Bank Term Loan. The Austin senior secured priority facility bears interest at 10% per annum on the first $24 million, 15% per
annum on the next $12 million and 20% per annum on the last $24 million.

|(12) | Subsidiaries of TPG/CalSTRS (the borrowers) were unable to repay the loans by the maturity date of March 6, 2010 and therefore, the loans are in
default. We are in discussions with the special servicer regarding a cooperative resolution on each of these assets, including either through a restructure of the debt, a sale or other transfer of the properties or the appointment of a receiver.
Pending a resolution of these loan defaults, we expect that we will continue to manage the properties pursuant to our management agreement with the borrowers. The management and leasing agreements expired on March 1, 2010, and are automatically
renewed for successive periods of one year each, unless we elect not to renew the agreements. Due to the maturity date default, the lender has the authority to terminate us as the property manager. If the borrowers are unable to extend or refinance
these loans, the lender could repossess the properties through foreclosure, which would result in a loss of fee revenue for us. The borrowers are accruing interest on these loans at a default rate, which ranges from 10.3% to 10.5% per annum
beginning on the maturity date of March 6, 2010.

Cash Flows

Comparison of nine months ended September 30, 2010 to nine months ended September 30, 2009.

Our cash flows from operating activities is primarily dependent upon the occupancy level of our portfolio, the rental rates achieved on
our leases, the collectability of rent and recoveries from our tenants, revenues generated and collected from our investment advisory, management, leasing and development services and the level of operating expenses and other general and
administrative costs. Net cash used in operating activities decreased by $(4.6) million to $(1.7) million for the nine months ended September 30, 2010, compared to $(6.3) million for the nine months ended September 30, 2009. The decrease
is primarily due to an increase in the collection of leasing commission receivables of $0.8 million, a $2.2 million increase in other assets, and a $1.2 million decrease in tenant prepaid rent.

Our net cash related to investing activities is generally impacted by the sale of condominium units at Murano, contributions and
distributions related to our investments in unconsolidated real estate entities, the funding of development and redevelopment projects and recurring and non-recurring capital expenditures. Net cash provided by investing activities decreased by
$(7.2) million to $7.7 million for the nine months ended September 30, 2010 compared to cash provided of $14.9 million for the nine months ended September 30, 2009. We experienced a decline in expenditures for improvements to real estate
in the 2010 period. In 2009, we completed the final wrap-up work on the Murano condominium units. Additionally, we curtailed our construction and development activity during the fourth quarter of 2008, which continued through 2009 and 2010. The
decrease in investing cash flows in 2010 was also attributed to a decrease of proceeds related to the sale of fewer Murano condominiums in 2010 as compared to 2009. Finally, we made contributions to our unconsolidated real estate entities in 2010 of
$13.6 million primarily in connection with the refinancing of loans for City National Plaza and three Houston projects.

Our
net cash related to financing activities is generally impacted by our borrowings, and capital activities net of dividends and distributions paid to common stockholders and non-controlling interests. Cash provided by financing activities for the nine
months ended September 30, 2010 increased by $28.2 million to $1.2 million compared to a use of cash of $(27.0) million for the nine months ended September 30, 2009. The increase was primarily due to the receipt of $15.1 million of net
proceeds from the sale of shares of common stock in our at-the-market equity offering program as well as a $2.4 million increase in restricted cash in lender controlled lockbox accounts. In December 2009, our board of directors suspended
our quarterly dividend to operating partnership unitholders and stockholders, which increased our cash flow by $3.4 million when comparing the nine months ended September 30, 2010 to the comparable period of 2009. These increases in cash flow
were offset by $17.3 million in loan paydowns on our Four Points Centre and Murano loan in 2010, and a $6.8 million decrease in loan draws as we were drawing on our Murano and Four Points Centre construction loans in the 2009 period. The
construction on both projects was completed in 2009.

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 in real estate taxes and operating expenses may be partially offset by the
contractual rent increases and expense reimbursements as described above. We have one multi-family residential rental property, which is located in the Philadelphia central business district and subject to short-term leases. Inflationary increases
can often be offset by increased rental rates; however, a weak economic environment may restrict our ability to raise rental rates.



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

A primary market risk faced by our company is interest rate risk. Our strategy is to match as closely as possible the expected holding periods and income streams of our assets with the terms of our debt.
In general, we use floating rate debt on assets with higher growth prospects and less stability to their income streams. Correspondingly, with respect to stabilized assets with lower growth rates, we will generally use longer-term fixed-rate debt.
As of September 30, 2010, 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 $1.98 billion, of which $0.5 billion bears interest at floating rates. As of September 30, 2010, interest rate caps have been purchased for
$0.3 billion of the floating rate loans.

Our fixed and variable rate consolidated long-term debt at September 30, 2010
consisted of the following (in thousands):

We utilize sensitivity
analyses to assess the potential effect of our variable rate debt. At September 30, 2010, our variable rate long-term debt represents 21.3% of our total long-term debt. If interest rates were to increase by 75 basis points, or by approximately
12.7% of the weighted average variable rate at September 30, 2010, the net impact would be increased interest costs of $0.5 million per year.

As of September 30, 2010, the fair value of our mortgage and other secured loans and unsecured loan aggregate $281.1 million, compared to the aggregate carrying value of $301.96 million.



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

Evaluation of
Disclosure Controls and Procedures

We have adopted and maintain disclosure controls and procedures that are designed to
ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act, as amended (the Exchange Act), is recorded, processed, summarized and reported within the time periods specified in
the rules and forms of the Securities and Exchange Commission (SEC) and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow
for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable
assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

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



Changes in Internal Controls over Financial Reporting

There were no changes in our internal control over financial reporting as defined in Rules 13a-15(f) or 15(d)-15(f) under the Exchange Act that occurred during the quarter ended September 30, 2010
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on
Controls

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

PART II.
OTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

We are
involved in various litigation and other legal matters from time to time, including personal injury claims and administrative proceedings, which we are addressing or defending in the ordinary course of business. Management believes that any
liability that may potentially result upon resolution of such matters will not have a material adverse effect on our business, financial condition or results of operations.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

Risks Related to Our
Business and Our Properties

We generate a significant portion of our revenues from our joint venture and our separate account
management agreements with CalSTRS, and if we were to lose these relationships, our financial results would be significantly negatively affected.

Our joint venture and separate account management agreement relationships with CalSTRS provide us with substantial fee revenues. For the three and nine months ended September 30, 2010, approximately
20.8% and 20.9%, respectively, of our revenue has been derived from fees earned from these relationships.

We cannot assure
you that our joint venture and separate account management relationships with CalSTRS will continue, and, if they do not, we may not be able to replace these relationships with other strategic alliances that would provide comparable revenues. Our
interest in the TPG/CalSTRS joint venture is subject to a buy-sell provision, which permits CalSTRS to purchase our interest in TPG/CalSTRS at any time. Under the buy-sell provision either our Operating Partnership or CalSTRS can initiate a buy-out
of the others interest at any time 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, upon the occurrence of certain events of default
by the Operating Partnership under the joint venture agreement or related management, development service and leasing agreements, upon bankruptcy of our Operating Partnership, or upon the death or disability of either James A. Thomas, our
Chairman, President and CEO, or John R. Sischo, our Co-Chief Operating Officer, or the failure of either of them to devote the necessary time to perform their duties (unless replaced by an individual approved by CalSTRS) (each, a Buyout
Default), CalSTRS may elect to purchase our joint venture interest based on a three percent discount to the appraised fair market value at the time of the Buyout Default.

The joint venture agreement with CalSTRS also prohibits any transfer of securities of the Company or limited partnership units in our
Operating Partnership that would result in Mr. Thomas, his immediate family and any entities controlled thereby owning less than 30% of our securities entitled to vote for the election of directors; provided, that in connection with the
issuance of additional Company shares in one or more public offerings, Mr. Thomas, his immediate family and controlled entities may reduce their collective ownership interest to no less than 10% of the total common shares and Operating
Partnership units and no less than 15.0 million shares and Operating Partnership units on a collective basis.

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 would 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.

##### Table of Contents



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.

Many of our operating properties are owned through a joint venture or partnership with other parties. As a result, we do not exercise sole decision-making authority regarding such joint venture
properties, including with respect to cash distributions or the sale of such properties. Furthermore, we may co-invest in the future through other partnerships, joint ventures or other entities, acquiring non-controlling interests or sharing
responsibility for managing the affairs of a property, partnership or joint venture. Investments in partnerships, joint ventures, funds or other entities may, under certain circumstances, involve risks, including partners who may have economic or
other business interests or goals which are inconsistent with our business interests or goals and may be in a position to take actions contrary to our policies or objectives. These investments may also have the risk of impasses on significant
decisions, because neither we nor our partner or co-venturer would have full control over the partnership or joint venture. Future 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 became bankrupt and defaulted on its reimbursement and contribution obligations to us, subjecting the property owned by the partnership or joint venture to liabilities in
excess of those contemplated by the partnership or joint venture agreement, or incurred debts or liabilities on behalf of the partnership or joint venture in excess of the authority 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 such partnership by investing through a subsidiary.

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

As of September 30, 2010, we held interests in 22 of our properties through TPG/CalSTRS, 10 of which are held indirectly through TPG/CalSTRS interest in the Austin Portfolio Joint Venture.
TPG/CalSTRS requires a unanimous vote of the joint ventures management committee on certain major decisions, including approval of annual business plans and budgets, financings and refinancings, and additional capital calls not in compliance
with an approved annual plan. The management committee currently consists of two members appointed by CalSTRS and one member appointed by the Operating Partnership. All other decisions, including sales of properties, are made based upon a majority
decision of the management committee. Thus CalSTRS has the ability to control certain decisions for the joint venture that may result in an outcome contrary to our interests. The Operating Partnership has the responsibility and authority to carry
out day to day management of the joint venture and to implement the annual plans approved by the management committee. 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 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. 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 one or more 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.

In June 2007, a wholly-owned subsidiary of TPG/CalSTRS, entered into a partnership agreement and syndication agreement with an affiliate
of Lehman Brothers, Inc. (Lehman) in relation to the Austin Portfolio Joint Venture. As of September 30, 2010, one-third of the Lehman affiliates original 75% equity interest in the Austin Portfolio Joint Venture had been sold
to an unrelated institutional investor and the Lehman affiliate held 50% of the equity in the Austin Portfolio Joint Venture. The Lehman affiliate has the right to reduce or eliminate certain fees and payments otherwise payable to TPG/CalSTRS under
the partnership agreement. The Lehman affiliate has certain approval rights with respect to major decisions of the Austin Portfolio Joint Venture, although the TPG/CalSTRS subsidiary is in charge of operating, leasing and managing the Austin
Portfolio Joint Venture assets within approved budgets and guidelines.

The major decision approval rights of the Lehman
affiliate 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 other limited partner in the Austin Portfolio Joint Venture also has approval rights over some of these major decisions.

##### Table of Contents



In addition, the
Lehman affiliate can require the sale of one Central Business District asset and one suburban asset by the Austin Portfolio Joint Venture at any time after June 1, 2011; further, the Lehman affiliate and its successors and assigns can require
the sale of the balance of the Austin Portfolio Joint Venture assets after June 1, 2012, in each case subject to a right of first offer in favor of the other partners in the Austin Portfolio Joint Venture. The limited partners also have the
right to remove the general partner under certain circumstances. These rights could adversely affect TPG/CalSTRS and us.

We may not
receive funding from our joint venture partners in connection with proposed acquisitions, which could adversely affect our growth.

We have entered into, and may enter into in the future, certain joint venture acquisition arrangements with third parties in which we identify potential acquisition properties on behalf of the joint
venture, and a portion (in some cases, a substantial portion) of the capital required for each project would be funded by our joint venture partners. Although our joint venture partners have committed to fund property acquisitions, such joint
venture partners may decide not to fund a particular or any potential acquisition properties for any number of reasons, including such entities may not have the capital necessary to fund projects at the time of the proposed acquisition. This may be
particularly relevant in light of the liquidity issues that many real estate funding sources have faced during the recent credit crisis. Accordingly, if we identify potential acquisition opportunities in the future for these programs, we may not
receive approval and/or funding from joint venture partners, notwithstanding any prior commitments for funding. If we do not make any acquisitions under existing or future joint ventures, it could adversely affect our ability to grow our business in
accordance with our business plan.

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

As of September 30, 2010, the 20 largest tenants for properties in which we held an
ownership interest collectively leased 31.5% of the rentable square feet of space at properties in which we hold an ownership interest, representing 38.0% of the total annualized rent generated by these properties.

Any of our tenants may experience a downturn in its business, which may weaken such tenants financial condition. As a result,
tenants may delay lease commencement, fail to make rental payments when due, decline to extend a lease upon its expiration, become insolvent, declare bankruptcy or default under their leases. Certain of our tenants also have termination rights under
their leases with us, which they might choose to exercise if they experience a downturn in their business. In addition, current economic and market conditions increase the possibility that one or more of our tenants will become insolvent. Any tenant
bankruptcy or insolvency, leasing delay, failure to make rental payments when due, or default under a lease could result in the termination of the tenants lease and material losses to our Company.

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

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
unique or disproportionate economic downturns or adverse regulatory or taxation policies in any of 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.

##### Table of Contents



A decrease in the
demand for office space in these geographic regions, and for 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 also
susceptible to disproportionate or unique adverse developments in these regions and in the national office market generally, such as business layoffs or downsizing, industry slowdowns, relocations of businesses, changing demographics, terrorist
targeting of high-rise structures, infrastructure quality, increases in real estate and other taxes, costs of complying with government regulations or increased regulation, oversupply of or reduced demand for office space, and other factors. 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 one or more of our
regions, 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 decline 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 need for additional debt financing, our existing level of debt and the limitations imposed by our debt agreements could have significant adverse consequences on us.

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



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



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



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



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



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



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



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



| |  |  | a default under any one of our mortgage loans with cross default provisions could result in a default on other of our 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 determines it is prudent.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If any one or more 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 could impair our ability to satisfy our debt service obligations.

Because we have a substantial amount of debt at our unconsolidated properties which bears interest at variable rates, our failure to hedge effectively against interest rate changes may adversely affect
our results of operations.

As of September 30, 2010, $0.5 billion of our unconsolidated debt was at variable interest
rates for which we had purchased interest rate caps covering $0.3 billion of the unconsolidated floating rate loans. The interest rate hedging arrangements we enter into to cap our interest rate exposure involve risks, including that our hedging
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 approximately 20 markets in the United States for strategic opportunities
to acquire office, mixed-use and other properties. Our ability to acquire properties on favorable terms and successfully operate them is subject to the following significant risks:



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



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



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



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



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



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



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



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

If we cannot complete property acquisitions on favorable terms or at all, or operate
acquired properties to meet our expectations, our revenue and profitability could be adversely impacted.

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

Our business strategy includes acquisitions and investments in real estate on an ongoing basis as market conditions warrant. These acquisitions may cause disruptions in our operations and divert
managements attention from our other day-to-day operations, which could impair our relationships with our current tenants and employees. 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, which could harm our results of operations.

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

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



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



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



| |  |  | we may not complete 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;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | occupancy rates and rents, or condominium prices and absorption rates in the case of the Murano, may fluctuate depending on a number of factors,
including market and economic conditions, and may result in our investment not being profitable;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

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

If we are not successful in our property development initiatives, it could adversely impact our revenue and profitability, causing a significant downturn in our business, including our financial
condition, results of operations, and the trading price of our common stock.

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 managers
and owners of office and mixed-use real estate, many of which own or manage 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, 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 and operating results.

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 September 30, 2010, leases representing 3.4% and 3.2% of the rentable square feet of the office and mixed-use properties in which we held an ownership interest will expire in 2010 and 2011,
respectively. Further, an additional 16.1% of the square feet of these properties was available for lease as of September 30, 2010. Current economic and real estate market conditions have resulted in depressed leasing activity recently as a
result of tenant unwillingness to make long term leasing commitments given recent upheaval in the financial markets, and it is unclear how long this market condition may continue. 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.

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. As a result of the recent downturn in the financial markets, we may experience difficulty refinancing some of our existing debt or obtaining new debt to complete acquisitions. Any additional debt we incur
will increase our leverage and may impose operating restrictions on us. Any issuance of equity by our company to fund our portion of equity capital requirements could be dilutive to our existing stockholders, and could have a negative impact on our
stock price. Our access to third-party sources of capital depends, in part, on:



| |  |  | our current debt levels, which were $301.96 million of consolidated debt and $1.98 billion of unconsolidated debt as of September 30, 2010;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our current cash flow from operating activities, which resulted in a use of cash of $1.7 million for the nine months ended September 30,
2010;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



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



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



| |  |  | the market price 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 when needed, we may not be able to acquire or develop properties when strategic opportunities exist, or to repay existing debt as it matures.

As a result of the limited time 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 properties 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, and any failure of properties to perform as expected, could adversely impact our revenue and profitability, causing a significant downturn in our financial condition, results of
operations and the trading price of our common stock and impairing our ability to satisfy our debt service obligations.

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

We intend to expand our business to new geographic regions where we expect the 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 lack of familiarity could adversely affect our ability to own, manage or develop properties outside these regions successfully or at all or to achieve expected performance.

As the current or previous owner or
operator of real property, we could become subject to liability for environmental contamination, regardless of whether we caused such contamination.

Under various federal, state and local environmental laws, regulations and ordinances, a current or previous owner or operator (e.g., tenant or manager) of real property may be liable for the cost to
remove or remediate contamination resulting from the presence or discharge of hazardous or toxic substances, wastes or petroleum products on, under, from or in such property. These costs could be substantial and liability under these laws may attach
without regard to fault, or whether the owner or operator knew of, or was responsible for, the presence of the contamination. The liability 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. In addition, the current or previous owner or operator of property may be subject to damage awards for personal injury or property damage resulting from contamination at or migrating from its property. Previous owners used some
of our properties for industrial and retail purposes, so those properties may contain some level of environmental contamination. In addition, the presence of contamination, or the failure to properly remediate contamination on a property may limit
the ability of the owner or operator to sell, develop or rent that property or to borrow using the property as collateral, and may cause our investment in that property to decline in value.

As the owner of real property, we could become subject to liability for asbestos-containing building materials in the buildings on our property.

Some of our properties may contain asbestos-containing materials. Environmental laws require that owners or operators of buildings with
asbestos-containing building materials properly manage and maintain these materials, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other abatement, in the event that
asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators for failure to comply with these requirements. In addition, these laws may also allow third parties to seek
recovery from owners or operators for personal injury associated with exposure to asbestos-containing building materials.

We
have removed or abated asbestos-containing building materials from certain tenant and common areas at our City National Plaza and Brookhollow properties. We continue to remove or abate asbestos from various areas of the building structures and as of
September 30, 2010, had accrued approximately $0.9 million for estimated future costs of such removal or abatement at these properties.

Our properties may contain or develop harmful mold or suffer from other adverse conditions, which could lead to liability for adverse health effects
and costs of remediation.

When excessive moisture accumulates in buildings or on building materials, mold growth may
occur, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants. Indoor air quality issues can also stem from inadequate ventilation, chemical
contamination from indoor or outdoor sources and other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants above certain levels can be alleged to cause a variety of adverse health effects and
symptoms, including allergic or other reactions. As a result, the presence of significant mold or other airborne contaminants at any of our properties could require us to undertake a costly remediation program to contain or remove the mold or other
airborne contaminants from the affected property or increase indoor ventilation. In addition, the presence of significant mold or other airborne contaminants could expose us to liability from our tenants, employees of our tenants and others if
property damage or health concerns arise.

As the owner of real property, we could become subject to liability for failure to comply with
environmental requirements regarding the handling and disposal of regulated substances and wastes or for non-compliance with health and safety requirements.

Environmental laws and regulations regarding the handling of regulated substances and wastes apply to our properties. The properties in our portfolio are also subject to various federal, state and local
health and safety requirements, such as state and local fire requirements. If we or our tenants fail to comply with these various requirements, we might incur governmental fines or private damage awards. Moreover, we do not know whether existing
requirements will change or whether future requirements will require us to make significant unanticipated expenditures that will materially adversely impact our financial condition, results of operations, cash flow, cash available for distribution,
the per share trading price of our common stock and our ability to satisfy our debt service obligations. Environmental noncompliance liability could also affect a tenants ability to make rental payments to us.



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 at the time of our public offering to indemnify Mr. Thomas against adverse direct and indirect tax consequences in the event that our Operating Partnership or the underlying property owner 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 14.7%
of annualized rent for properties in which we held an ownership interest as of September 30, 2010. The indemnification obligation currently expires October 13, 2013, which may be further extended to October 13, 2016 provided
Mr. Thomas and his controlled entities collectively retain at least 50% of the Operating Partnership units received by them in connection with our formation transactions at the time of our initial public offering.

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

Risks Related to the Real Estate Industry

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

The success of our business and profitability of our operations are dependent on continued investment
in the real estate markets and access to capital and debt financing. A long term crisis of confidence in real estate investing and lack of available credit for acquisitions would be likely to constrain our business growth. As part of our business
goals, we intend to grow our properties portfolio with strategic acquisitions of core properties at advantageous prices, and core plus and value added properties where we believe we can bring necessary expertise to bear to increase property values.
In order to pursue acquisitions, we need access to equity capital and also property-level debt financing. Current conditions in the financial markets may adversely impact our ability to refinance existing debt and the availability and cost of credit
in the near future. Presently, access to capital and debt financing options continue to be restricted and it is uncertain how long current economic circumstances may last. Any consideration of sales of existing properties or portfolio interests may
be tempered by the depressed nature of property values at present. Our ability to make scheduled payments or to refinance our obligations with respect to indebtedness depends on our operating and financial performance, which in turn is subject to
prevailing economic conditions.

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 our results of operations and the value of our properties. These events include:



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



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



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



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



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



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



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



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



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



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

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

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

All of our commercial properties are required to comply with the Americans with Disabilities Act, or ADA. The ADA has separate compliance requirements for public accommodations and
commercial facilities, but generally requires that buildings be made accessible to people with disabilities. The obligation to make readily achievable accommodations is an ongoing one, and we assess our properties and make alterations as
appropriate. Compliance with the ADA requirements could require removal of access barriers.

If one or more of our properties
is not in compliance with the ADA, we would be required to incur additional costs to bring the property or properties into compliance. In addition, non-compliance could result in imposition of fines by the U.S. government or an award of damages to
private litigants, or both. Typically, we are responsible for changes to a building structure that are required by the ADA, which can be costly. In addition, we are required to operate our properties in compliance with fire and safety regulations,
building codes and other land use regulations. We may be required to make substantial capital expenditures to comply with these requirements thereby limiting the funds available to operate, develop and redevelop our properties and acquire additional
properties. As a result, these expenditures could negatively impact our revenue and profitability.

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

We carry comprehensive liability, fire, flood, extended coverage, wind, earthquake, terrorism, pollution legal liability, business interruption and rental loss insurance under our blanket policy covering
all of the properties in which we own an interest in or manage for third parties, including our development properties (although we carry only liability insurance for the California Environmental Protection Agency (CalEPA) headquarters
building under our blanket policy because the tenant has the right to provide all other forms of coverage it deems necessary, and it has elected to do so). We believe the policy specifications and insured limits are appropriate and adequate given
the relative risk of loss, the cost of the coverage and industry practice.

We either own or have interests in a number of
properties in Southern California, an area especially prone to earthquakes. We carry earthquake insurance on our properties located in seismically active areas, which includes our Southern California properties, wind insurance on our properties
located in tier 1 wind zones, which includes our Houston, Texas properties, and terrorism insurance on all of our properties. Our terrorism insurance is subject to exclusions for loss or damage caused by nuclear substances, pollutants,
contaminants, and biological and chemical weapons as more specifically excluded under the actual terrorism policies. Some of our policies, like those covering losses due to earthquakes and terrorism, are subject to limitations involving deductibles
and policy limits which may not be sufficient to cover potential losses.

Under their leases, our 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 the property was irreparably damaged. In the event of a significant
loss at one or more of the properties covered by our 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.

In addition to the common stock owned by Mr. Thomas as of September 30, 2010, he owned or controlled a
significant interest in our Operating Partnership consisting of 13,813,331 units, or a 28.0% interest in the Operating Partnership as of such date. In addition, our senior executive officers, excluding Mr. Thomas, collectively held an interest
in incentive units (vested and unvested) representing an aggregate 3.7% equity interest in the Operating Partnership.

Members of senior
management could make decisions that could have different implications for our Operating Partnership and for us, our stockholders, and our senior executive officers. For example, dispositions of interests in One Commerce Square or Two Commerce
Square could trigger our tax indemnification obligations with respect to Mr. Thomas.

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

We depend on the efforts of key personnel,
particularly Mr. Thomas, our Chairman, Chief Executive Officer, and President. Among the reasons that Mr. Thomas is important to our success is that he has an industry reputation developed over more than 30 years in the real estate
industry that attracts business and investment opportunities and assists us in negotiations with lenders, existing and potential tenants and industry personnel. If we lost his services, our relationships with these parties could diminish.
Mr. Thomas is 74 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. Randall L. Scott, our Executive Vice President and Director, 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, in addition to being our co-Chief Operating Officer, is responsible for our investment efforts, including acquisition, financing and capital markets relationships. Thomas S. Ricci, our Executive Vice President, has been extensively
involved in the development of large, mixed-use and commercial projects. Diana M. Laing, our Chief Financial Officer and Secretary, has served as chief financial officer of two publicly-traded real estate investment trusts. Paul S. Rutter, our
co-Chief Operating Officer & General Counsel, has extensive experience, both as a real estate lawyer and as an executive in commercial real estate, including acquisitions, financing, joint ventures and leasing of office and mixed use
projects. Todd L. Merkle, our Chief Investment Officer, has significant experience in real estate investment banking as well as property acquisitions, dispositions and financing. While we believe that we could find acceptable replacements for these
executives, the loss of any 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, pursuant to a right granted to CalSTRS in our joint venture agreement with CalSTRS, the possible required sale of our joint venture interest
to CalSTRS at 97% of fair value, unless within 180 days the Company names a replacement for such departed executive who is reasonably acceptable to CalSTRS.

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. These loans generally contain lockbox arrangements and reserve requirements that may affect the amount of cash
available for distribution from the subsidiaries that own the properties to the Operating Partnership. Some of the loans include cash sweep 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 any of these loans, the defaulting subsidiary or joint venture would be prohibited from distributing cash to our Operating Partnership. As a
result, our Operating Partnership may be unable to distribute funds to us and we may be unable to use funds from one property to support the operation of another property. As we acquire new properties and refinance our existing properties, we may
finance these properties with new loans that contain similar provisions. Some of the loans to our subsidiaries and joint ventures may contain provisions that restrict us from loaning funds to our other subsidiaries or joint ventures. If we are
permitted to loan funds to our subsidiaries or joint ventures, our loans generally will be subordinated to the existing debt on our properties.

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

Each entity that received Operating Partnership units in our formation transactions received shares of our limited voting stock that are
paired with units in our Operating Partnership on a one-for-one basis. All of these entities are directly or indirectly controlled by Mr. Thomas, and, as a result, Mr. Thomas controls 100% of our outstanding limited voting stock, or 31.1%
of our outstanding voting stock (including outstanding shares of common stock owned by Mr. Thomas and his affiliates) as of September 30, 2010. These limited voting shares are entitled to vote in the election of directors, for the approval
of certain extraordinary transactions including any merger, sale or liquidation 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.

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 potentially
providing them with the opportunity to sell their shares at a premium over the then market price. Our certificate of incorporation and bylaws contain provisions which may deter takeover attempts, 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 our stockholders. These terms may include voting rights, including the right to
vote as a series on particular matters, preferences as to dividends and liquidation, conversion rights, redemption rights and sinking fund provisions. The issuance of any preferred stock could diminish the rights of holders of our common stock, and
therefore could reduce the value of our common stock. In addition, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell assets to, a third party. The ability of our board of
directors to issue preferred stock could make it more difficult, delay, discourage, prevent or make it more costly to acquire or effect a change in control, thereby preserving the current stockholders control of our Company.

Finally, we are also subject to Section 203 of the Delaware General Corporation Law which, subject to certain exceptions, prohibits
a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that such 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 which could 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 to classify or reclassify any unissued shares of our preferred stock and to set the preferences, rights and other terms of the classified or unclassified shares. Our board of directors 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 interests of our
stockholders.

The payment of dividends on our common stock is at the discretion of our board of directors and subject to various
restrictions and considerations and, consequently, may be changed or discontinued at any time.

Although we have
historically paid quarterly dividends on our common stock until December 2009, the payment of cash dividends in the future, if any, will be at the discretion of our board of directors and will depend upon such factors as earnings levels, capital
requirements, our overall financial condition, and any other factors deemed relevant by our board of directors. In December 2009, our board of directors suspended the quarterly dividends to common stockholders. If the dividend payments are
reinstated, such quarterly dividend payments may be further reduced or stopped again altogether in the future, in which case the only opportunity to achieve a positive return on an investment in our common stock would be if the market price of our
common stock appreciates.
