COMPANY BACKGROUND

Thomas Properties Group, Inc. (TPGI) is a full-service real estate operating company that owns, acquires, develops and manages primarily office, as well as mixed-use and residential properties on a nationwide basis. Our company’s primary areas of focus are the acquisition and ownership of premier properties (through strategic joint ventures), property development and redevelopment, and investment and property management activities.

Our properties are located in Southern California and Sacramento, California; Philadelphia, Pennsylvania; Northern Virginia; Houston, Texas; and Austin, Texas. As of September 30, 2009, we own interests in and asset manage 27 operating properties with 13.2 million rentable square feet and provide asset and/or property management services on behalf of third parties for an additional four operating properties with 2.2 million rentable square feet.

Our Investment Management Platform

Our sponsorship of partnerships and joint ventures provides us with additional institutional capital for investment and shared risk exposure. These arrangements provide us with the opportunity to earn fees for asset management, property management, leasing and other services, as well as possible carried interest or promote fees.

Our Thomas High Performance Green Fund is intended to invest in commercial properties to be developed or redeveloped into high performance, energy-efficient, high productivity buildings. The fund currently has total capital commitments of $180 million, of which we have committed $50 million, and all of which is unfunded. The Green Fund is expected to invest nationally, focusing on markets with green sensibility and attractive office fundamentals. Green Fund investments will potentially seek ratings from the U. S. Green Building Council’s LEED Green Building Rating System.

TPG/CalSTRS is a value-add/core-plus joint venture with total capital commitments of $378.3 million of which $6.6 million is unfunded. Additionally, CalSTRS and TPG are committed to fund up to $3.75 million and $1.25 million, respectively, as may be required to fund temporary operating cash shortfalls. This joint venture, in which we own a 25% interest, currently owns twelve office properties. The joint venture also holds a 25% interest in a joint venture which owns an additional ten office properties in Austin, Texas.

Our Fee Services

We have been engaged by NBC Universal to entitle and master plan approximately 124 acres on their Universal Studios Hollywood backlot for housing and related retail and community-serving uses. We are pursuing environmental clearance and governmental approvals for approximately 2,937 residential units and 180,000 square feet of retail and community-serving space. We earn a monthly developer fee on this project.

We have been retained by Korean Air, a subsidiary of Hanjin Group, as fee developer for the entitlement, design and redevelopment of the 2.7 acre Wilshire Grand property in downtown Los Angeles, for which we are proposing the development of two buildings to include approximately 1.5 million square feet of office, 560 hotel rooms, and 100 residential condominiums, with supporting retail and restaurant uses, for a total project size of up to approximately 2.5 million gross square feet. We earn a monthly developer fee on this project.

Significant Recent Events

On October 10, 2009, the Campus El Segundo construction loan in the amount of $17.0 million was modified. The loan has been extended to July 31, 2011, and has three one-year extension options at our election subject to our compliance with certain loan covenants.

On October 13, 2009, the Four Points Centre construction loan was modified. The loan has been extended to July 31, 2012 with two one-year extension options subject to certain conditions.

On October 14, 2009, we entered into a discounted payoff agreement with the holders of the existing mezzanine debt on Two Commerce Square. We have agreed to pay off the two mezzanine loans, with a principal amount of approximately $36.1 million, for a discounted amount of $25.0 million on or before November 30, 2009 (subject to an extension right of up to 29 days).

On October 6, 2009 we sold a 1.9 acre land parcel adjacent to our Four Points Centre development property in Austin, Texas, which is subject to a ground lease to a retail tenant. The land was sold for $2.1 million; we expect to recognize a gain of approximately $1.2 million in the fourth quarter, 2009.

Continuing the momentum generated during the Murano accelerated marketing event held on June 27, 2009, we entered into contracts for an additional 24 units and settled 56 units during the quarter; resulting in approximately a $25.0 million reduction in our construction loan balance. Subsequent to September 30, 2009, we have entered into contracts to sell an additional six units.

Supplemental Financial Information

OPERATING AND FINANCIAL INFORMATION

Financial Measures

This supplemental financial information includes certain financial measures prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) under the full consolidation accounting method, and certain financial measures prepared in accordance with the pro-rata consolidation method (non-GAAP). Along with net income, we use two additional measures, Earnings before Depreciation, Amortization and Deferred Taxes (“EBDT”) and After Tax Cash Flow (“ATCF”), to report operating results. EBDT and ATCF are non-GAAP financial measures and may not be directly comparable to similarly-titled measures reported by other companies. We believe the financial measures presented under the pro-rata consolidation method provide supplemental information helpful to an understanding of our results of operations. Although these financial measures are not presented in accordance with GAAP, we believe these measures assist investors in understanding our business and operating results. We believe this information provides useful supplemental data regarding the underlying economics of our business operations because operating results presented under GAAP may include items that are nonrecurring or not necessarily relevant to ongoing operations, or difficult to forecast for future periods. Management uses these non-GAAP financial measures to review our company’s operating results for comparative purposes with respect to previous periods or forecasts, and also to evaluate future prospects. Our investors can also use these non-GAAP financial measures as supplementary information to evaluate operating performance. Our non-GAAP financial measures are not intended to be performance measures that should be regarded as alternatives to, or more meaningful than, our GAAP financial measures. Non-GAAP financial measures have limitations as they do not include all items of income and expense that affect our operations, and accordingly should always be considered as supplemental to our financial results presented in accordance with GAAP.

Pro-Rata Consolidated Statements of Operations and Pro-Rata Consolidated Balance Sheets

Included are pro-rata consolidated statements of operations, as well as pro-rata consolidated balance sheets, because we believe this information is useful to investors as this method reflects the manner in which we operate our business, and provides more detailed information regarding the operations of the unconsolidated investments. We have made investments in which our economic ownership is less than 100% as a means of procuring additional investment opportunities and sharing risk. A significant amount of our business activity has and will continue to be conducted through our unconsolidated investments. Under GAAP, these investments are not consolidated in our financial statements. Under the pro-rata consolidation method, we present the results of our investments proportionate to our share of ownership. Our management considers the performance of our unconsolidated investments both individually and as a contributing factor to our operating performance for purposes of financial planning and making operating decisions. We believe this presentation of the performance of our unconsolidated investments is helpful to investors in understanding and evaluating our current operating performance as well as for purposes of period-to-period comparisons. We provide reconciliations from the full consolidation method to the pro-rata consolidation method in this supplemental financial information.

Earnings Before Depreciation, Amortization and Deferred Taxes (EBDT) and After Tax Cash Flow (ATCF)

EBDT and ATCF are non-GAAP financial measures and may not be directly comparable to similarly-titled measures reported by other companies. We present these financial measures under the pro-rata consolidation method to provide supplemental information helpful to an understanding of our results of operations. Although these financial measures are not presented in accordance with GAAP, we believe these measures assist investors in understanding our business and operating results. EBDT and ATCF reflect operating performance measurements for our company that assist management in evaluating trends for comparative and planning purposes. However our non-GAAP financial measures are not intended to be regarded as alternatives to, or more meaningful than, our GAAP financial measures.

See page 10 for a discussion of EBDT and a reconciliation of EBDT to net income (loss) and page 12 for a discussion of ATCF and a reconciliation of ATCF to net income (loss).

EARNINGS BEFORE DEPRECIATION, AMORTIZATION AND TAXES (EBDT) (NON-GAAP)

(in thousands, except share and per share data)

(unaudited)

We use EBDT as a supplemental performance measure. EBDT excludes the following items: i) income tax expense (benefit); ii) noncontrolling interests; iii) non-cash charges for depreciation and amortization; and iv) amortization of loan costs. EBDT provides a performance measure that, when compared year over year, reflects the impact to operations from changes in occupancy, rental rates, operating costs, development and redevelopment activities, general and administrative expenses, and interest costs; and EBDT provides perspective on operating performance not immediately apparent from net income. EBDT should be considered only as a supplement to net income as a measure of our performance. EBDT also assists our management in identifying trends for purposes of financial planning and forecasting results. However, the usefulness of EBDT as a performance measure is limited and EBDT should not be used as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs. EBDT also should not be used as a supplement to or substitute for cash flow from operating activities (computed in accordance with GAAP) or as an alternative to net income (loss) as an indicator of our operating performance.

We define ATCF as net income (loss) excluding the following items: i) income tax expense (benefit); ii) noncontrolling interests; iii) non-cash charges for depreciation, amortization and asset impairment; iv) amortization of loan costs; v) non-cash compensation expense; vi) the adjustment to recognize rental revenues using the straight-line method; and vii) the adjustments to rental revenue to reflect the fair market value of rent. Our management utilizes ATCF data in assessing performance of our business operations in period to period comparisons and for financial planning purposes. ATCF should be considered only as a supplement to net income as a measure of our performance.

PORTFOLIO DATA AS OF SEPTEMBER 30, 2009 - CONTINUED

Footnotes to Portfolio Data on previous page:

(1) TPGI share information set forth in the table on the previous page is calculated by multiplying the applicable data for each property by our percentage ownership of each property.

(2) For purposes of the table on the previous page, both on-site and off-site parking is excluded. Total portfolio square footage includes office properties and mixed-use space (including retail), but excludes 168 apartment units at 2121 Market Street.

(3) Occupancy at stabilization is expected to be approximately 93%. Certain properties that have occupancy greater than 93% as of September 30, 2009 are not considered stabilized due to upcoming tenant vacancies not yet reflected.

(4) For properties currently stabilized, the estimated stabilized net operating income (NOI) represents the sum of i) the annual straight-line rent under existing leases which were in place as of September 30, 2009, calculated as if the leases began on September 30, 2009, and ii) estimated parking and other income, less estimated operating expenses and adjusted for non-recurring items. For properties expected to become stabilized in future years, estimated stabilized NOI represents the sum of i) the annual straight-line rent under existing leases which will be in place in the year the properties are stabilized, calculated as if the leases began at the point of stabilization, ii) the annual expected market rent for the remaining space (up to the stabilized occupancy percentage), and iii) estimated parking and other income, less estimated operating expenses and adjusted for non-recurring items.

(5) For properties currently stabilized, the estimated stabilized NOI – cash basis represents the sum of i) the annual cash rent under existing leases which were in place as of September 30, 2009, and ii) estimated parking and other income, less estimated operating expenses and adjusted for non-recurring items. For properties expected to become stabilized in future years, estimated stabilized NOI-cash basis represents the sum of i) the annual cash rent under existing leases which will be in place in the year the properties are stabilized, ii) the annual expected market rent for the remaining space (up to the stabilized occupancy percentage), and iii) estimated parking and other income, less estimated operating expenses and adjusted for non-recurring items.

(6) Expected capital expenditures to complete stabilization represent capital expenditures, including tenant improvements and leasing commissions, expected to be spent to complete the stabilization of the property.

(7) The square footage and occupancy information presented for 2121 Market Street represents the information for two retail/office tenants only; the estimated NOI includes 168 residential units comprising 132,823 square feet.

(8) Oak Hill Plaza and Walnut Hill Plaza are co-borrowers under a loan agreement. The entire loan balance is included on the Oak Hill Plaza line.

(9) Three of our Austin, Texas properties secure the Austin Portfolio bank term loan on a first mortgage basis and seven of our remaining Austin properties provide secondary equity pledges to secure the Austin Portfolio bank term loan of which our pro rata share is $7,165,000. The entire loan balance is included on the Westech 360 I-IV line. These mortgage liens and equity pledges also secure the Austin Portfolio senior secured priority financing payable to the partners (see note 8 on page 20), which has a priority right to repayment ahead of the Austin Portfolio bank term loan.

(10) We paid $2.225 million in June 2009 of which approximately $1.8 million is held by the lender for our use for project costs.

(1) We have been engaged by NBC Universal to entitle and master plan their Universal Studios Hollywood backlot on which we have a right of first offer (ROFO) to develop approximately 124 acres for residential and related retail and community-serving uses. We are pursuing environmental clearance and governmental approvals for approximately 2,937 residential units and 180,000 square feet of retail and community-serving space. Upon successful completion of the entitlement process and our exercise of the ROFO, it is anticipated this project will be developed in phases over several years, subject to market conditions.

(2) We have been engaged by Korean Air to entitle and master plan a 2.7 acre site in downtown Los Angeles for 2,500,000 square feet of development that consists of office, hotel, residential and retail uses.

(3) We have completed infrastructure improvements to our Campus El Segundo development site, including installing underground utilities, rough grading, and streetscape improvements. The first phase of development is anticipated to include a 225,000 square foot, six-story Class A office building and parking structure to be constructed on 2.7 acres, which we are currently marketing to prospective tenants.

(4) We are currently entitling this property, targeting approximately 1.5 million square feet. The first phase of this transit-oriented development is planned to become a television production facility and office space, in accordance with the space needs of NBC Universal. We expect to enter into a long-term ground lease with the Los Angeles Metropolitan Transportation Authority (which owns the land) upon completion of entitlements.

(5) Costs do not include approximately 1.9 acres of land with carrying value of $0.6 million related to a ground lease we have with a retail tenant. Subsequent to the third quarter, we sold this parcel to a third party buyer for a purchase price of $2.1 million.

(6) The number of acres excludes approximately 3.0 acres currently under contract for sale with a third party. This parcel is not encumbered by any debt and has a carrying value of approximately $3.9 million, of which TPGI’s share is approximately $1.0 million.

(7) We have a $25.1 million preferred equity interest in Murano. Excluding the preferred equity interest, we hold a 73% interest in the property.

DEBT SUMMARY – CONTINUED

Footnotes to Debt Summary on previous page:

(1) The senior mezzanine loan bears interest at a rate such that the weighted average rate on this loan and the rate on the mortgage loan secured by Two Commerce Square equals 9.2% per annum. The effective interest rate on the senior mezzanine loan as of September 30, 2009 was 19.3% per annum. On October 14, 2009, we entered into a discounted payoff agreement with the holders of the existing mezzanine debt on Two Commerce Square. We have agreed to pay off the two mezzanine loans, with a principal amount of approximately $36.1 million, for a discounted amount of $25.0 million on or before November 30, 2009 (subject to an extension right of up to 29 days). Subsequent to September 30, 2009, we deposited $6.0 million with the holders of the loans under the agreement, which deposit will be credited against the payoff amount on closing. If we exercise the 29 day extension right, the deposit will be increased by an additional $7.0 million.

(2) $9.9 million of this loan is secured by both a subordinate lien on the property and a payment guaranty issued by the partnership, which owns Oak Hill Plaza/Walnut Hill Plaza.

(3) $9.2 million of this loan is secured by both a subordinate lien on the property and a payment guaranty issued by the partnership, which owns Four Falls Corporate Center.

(4) We may borrow an additional $0.7 million under this construction loan. The Company has a completion guaranty for the Murano construction loan, which includes a guaranty of interest.

(5) The loan has one six-month extension option remaining. The extension option is subject to an exit fee equal to 0.5% of the outstanding principal balance and unfunded commitments and may be reduced to 0.25% if certain conditions are met. We expect to exercise this final six-month extension option, which would extend the maturity date to July 31, 2010.

(6) The loan has a remaining one-year extension option at our election.

(7) The loan has two one-year extension options at our election, subject to a debt service coverage ratio of 1:1.

(8) We and our partners in the Austin Portfolio replaced the unfunded $100 million commitment under a $292.5 million credit facility with $60 million of new senior secured priority financing committed to be funded by the partners. Approximately $14 million of this new financing was used to acquire at a discount and immediately retire third party term loan debt with an $80 million face value. $20 million of the $60 million commitment has been funded by the partners as of September 30, 2009. The remaining commitment will provide an ongoing source of capital for leasing costs and capital improvements. See also Note 10 below.

(9) The loan has two one-year extension options at our election.

(10) The Austin Portfolio bank term loan represents the modified balance under the amended credit agreement after third party term loan debt with a face value of $80 million was acquired at a discount for approximately $14 million and immediately retired. As a result, the previously funded loan of $192.5 million was reduced to $112.5 million. See also Note 8 above.

(11) The loan agreement was modified and the loan maturity was extended to July 31, 2011 with three one-year extension options, subject to our compliance with certain covenants, with a final maturity date of July 31, 2014 if all extension options are exercised. The lender has the right to require payment of $2.5 million at the time of each extension. The interest rate on the loan has been increased to LIBOR plus 3.75% per annum. We have guaranteed this loan.

(12) The loan agreement was modified and the loan maturity was extended to July 31, 2012 with two one-year extension options at our election subject to certain conditions. We have provided a completion guaranty and have guaranteed a portion of the principal and interest payable. We have also provided additional collateral of approximately 62.4 acres of fully entitled unimproved land, which is adjacent to our Four Points Centre office buildings. We have committed to pay down the principal amount of the loan in the total amount of $7.8 million of which $3.9 million was paid in October 2009 and the balance will be paid in three equal installments, in January, June and December, 2010. The interest rate on the loan has been increased to LIBOR plus 3.50%. We paid $2.225 million in June 2009 of which approximately $1.8 million is held by the lender to fund any remaining project costs, and $10.8 million remains unfunded and available to be drawn to fund any remaining project costs.

(13) 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.
