Recent Events

Parkway Properties, Inc. Merger

On September 4, 2013, TPGI entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Parkway Properties, Inc., (“Parkway”). Under the terms of the Merger Agreement, TPGI will merge with and into Parkway, with Parkway surviving the merger, and our Operating Partnership will merge with a wholly owned subsidiary of Parkway. Each outstanding share of common stock of TPGI will be canceled and converted into the right to receive 0.3822 shares (the “Exchange Ratio”) of common stock of Parkway, and each outstanding share of limited voting stock of TPGI will be canceled and converted into the right to receive limited voting stock of Parkway at the Exchange Ratio. Pursuant to the Merger Agreement, each outstanding limited partnership unit of TPGI's Operating Partnership will be converted into the right to receive common limited partnership units of Parkway Properties LP at the Exchange Ratio.

Special Meeting

TPGI will hold a Special Meeting of its Stockholders (the “Special Meeting”) on December 17, 2013. The record date for determination of stockholders entitled to vote at the Special Meeting has been set as the close of business on November 11, 2013. At the Special Meeting, TPGI’s stockholders will vote on the a proposal to approve the merger with Parkway and other proposals as described in the preliminary joint proxy statement/prospectus of TPGI and Parkway filed by Parkway with the Securities and Exchange Commission. Completion of the transaction is subject to the approval of shareholders of both companies and satisfaction of customary closing conditions.

Property Sale

On September 27, 2013, three properties in Northern Virginia (Fair Oaks Plaza and Reflections I and II), owned by TPG/CalSTRS, LLC (“TPG/CalSTRS”), a joint venture with CalSTRS, and subject to special servicer oversight as a result of mortgage loan defaults, were sold to an entity owned by three of TPG's executives (John Sischo, Randall Scott and Thomas Ricci), two of which are directors. TPG has no continuing involvement, commitments or obligations with respect to such properties. TPG/CalSTRS recognized a non-cash gain of approximately $14.3 million, of which TPG's share was approximately $2.2 million.

COMPANY BACKGROUND - CONTINUED

TPG/CalSTRS Liquidation

On September 30, 2013, pursuant to the Redemption and Liquidation Option Agreement ("Option Agreement"), TPG/CalSTRS was liquidated. Under the Option Agreement (a) TPG made a capital contribution to TPG/CalSTRS of approximately $166.3 million, (the "Contribution Amount"), (b) TPG/CalSTRS made a distribution to CalSTRS of all of the interests in the entities that owned City National Plaza, plus cash equal to the Contribution Amount, and (c) TPG/CalSTRS made a distribution to TPG of all of the interests in the entities that own San Felipe Plaza and CityWestPlace, which are now wholly-owned by TPG. TPG recognized a gain on the liquidation of the joint venture of approximately $118.2 million due to the transfer of our interest in City National Plaza to CalSTRS resulting in a gain of $62.7 million, and a remeasurement of our historical 25% interest in CityWestPlace and San Felipe Plaza upon the acquisition of the other 75% interest from CalSTRS, resulting in a gain of $55.5 million.

Parkway Loan

In connection with the execution of the Merger Agreement, TPG entered into an $80.0 million loan agreement with Parkway to fund a portion of TPG's obligations with respect to the TPG/CalSTRS liquidation. The loan with Parkway was funded on September 27, 2013, and bears interest at a rate of 6% per annum for the first six months, 8% per annum for the following six months, and 12% per annum thereafter, with interest payable monthly in arrears. If the merger with Parkway is not consummated, the loan will mature on January 15, 2015.

Litigation Relating to the Merger Transaction with Parkway

On October 24, 2013, a purported stockholder of TPGI filed a lawsuit entitled Osieczanek v. Thomas Properties Group, Inc., et. al. against TPGI and its directors, Parkway, and PKY Masters, LP in the Chancery Court of the State of Delaware. This action was brought as a putative class action, alleging that TPGI’s directors breached certain alleged duties to TPGI’s stockholders by failing to provide TPGI’s stockholders with material information in connection with the mergers and that Parkway aided and abetted those breaches. The lawsuit seeks various forms of relief, including that the court enjoin the merger and rescind the merger agreement. TPGI and its directors believe that this action is without merit.

Significant Leasing Activity

Subsequent to September 30, 2013, we entered into a long-term lease for 581,000 square feet with Statoil Gulf Services L.L.C., the U.S. upstream wholly-owned subsidiary of Norwegian energy company, Statoil ASA (Aa2/AA-), as their North American headquarters at CityWestPlace. Beginning with initial occupancy in mid-2015, Statoil will over time occupy the entirety of CityWestPlace Building 2, comprising 431,000 square feet, as well as extend their existing lease for 150,000 square feet in CityWestPlace Building 4. Statoil is significantly growing its presence at CityWestPlace from its current occupancy of 225,000 square feet.

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 non- GAAP financial measures. We believe the non-GAAP financial measures provide supplemental information helpful to an understanding of our results of operations and financial condition. Along with net income, we use After Tax Cash Flow (“ATCF”), to report operating results. ATCF is a non-GAAP financial measure and may not be directly comparable to similarly-titled measures reported by other companies. Although this financial measure is not presented in accordance with GAAP, we believe this measure assists investors in understanding our business and operating results by providing 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 are difficult to forecast for future periods. Management uses 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 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. See pages 6 - 9 for a discussion of ATCF and a reconciliation of ATCF to net income (loss).

AFTER TAX CASH FLOW (ATCF) (NON-GAAP)

(in thousands, except share and per share data)

(unaudited)

We define ATCF as net income (loss) excluding the following items: i) deferred 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; vii) the adjustments to rental revenue to reflect the fair market value of rent; viii) impairment loss; ix) gain on liquidation of joint venture; and x) gain (loss) on sale of real estate. 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. ATCF should not be used as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs. ATCF also should not be used as a substitute for cash flow from operating activities (computed in accordance with GAAP).

(5) For properties that are less than 95% leased, pro-forma annualized net operating income represents the sum of i) current annualized net operating income, and ii) an upward adjustment to net operating income based on current market rent to achieve 95% occupancy. For properties that are more than 95% leased, pro-forma annualized net operating income represents the sum of i) current annualized net operating income, and ii) a downward adjustment to net operating income based on average in place rent to achieve 95% occupancy.

(6) Currently committed leasing capital costs represent existing contractual obligations for tenant improvement and leasing commission costs for leases in place as of September 30, 2013. Estimated incremental leasing capital costs represents capital expenditures, including tenant improvements and leasing commissions, expected to be spent to achieve 95% occupancy.

(7) Brandywine Realty Trust ("BDN") has a 25% preferred equity position in the partnerships that own Commerce Square, for which it contributed $25.8 million. The preferred equity, which earns a preferred return of 9.25%, is being invested in a value-enhancement program designed to increase rental rates and occupancy at Commerce Square. Although TPGI's percentage interest has been reflected as 75%, the NOI amounts, leasing and capital cost amounts, and encumbrances are reflected at 100%, and the preferred equity balances and accrued preferred returns of $17.7 million and $11.4 million have been included in the encumbrances of One Commerce Square and Two Commerce Square, respectively.

(2) We consolidate our Murano residential condominium project which we control. Our unaffiliated partner's interest is reflected in our consolidated balance sheets under the "Noncontrolling Interests" caption. Our partner has a stated ownership interest of 27%. Net proceeds from the project are distributed based on an order of preferences described in the partnership agreement. The Company anticipates that we will receive distributions in excess of our stated 73% ownership interest according to these distribution preferences.

(3) The 35 units remaining to sell as of September 30, 2013 are all on high-rise floors with superior views. Subsequent to September 30, 2013, we closed the sales of nine units, which reduced the number of units remaining to be sold to 26, and two units remain under contract, which if they close, will bring the number of units remaining to be sold to 24.

DEBT SUMMARY - CONTINUED

Footnotes to Debt Summary on previous page:

In connection with some of the loans listed in the Debt Summary, our operating partnership is subject to customary non-recourse carve out obligations, in the case of consolidated assets; and TPG/CalSTRS is subject to customary non-recourse carve out obligations in the case of certain joint venture assets.

(1) The Four Points Centre loan bears interest at LIBOR plus 3.50%. As of September 30, 2013, the loan has an unfunded balance of $0.4 million which is available to fund any remaining project costs. The loan has a one year extension option at our election subject to certain conditions that will put the maturity date at the end of extension options as July 31, 2015. The option to extend is subject to (1) a loan-to-value ratio and a minimum appraised land ratio of 62.5%, and (2) the adjusted net operating income of the property and improvements as a percentage of the outstanding principal balance must be at least 10.0%. If these requirements are not met, we can pay down the principal balance in an amount sufficient to satisfy these requirements. The debt yield is calculated by dividing the net operating income of the property by the outstanding principal balance of the loan. Through September 30, 2013, the property has generated net operating losses.

Beginning in August 2014, we are required to pay down the loan balance by $42,000 each month. We have guaranteed completion of the tenant improvements and 46.5% of the balance of the outstanding principal balance and interest payable on the loan, which results in a maximum guarantee of $10.9 million as of September 30, 2013. We have agreed to certain financial covenants on this loan as the guarantor, which we were in compliance with as of September 30, 2013.

(2) TPG entered into a loan agreement with Parkway LP, in connection with a merger agreement, to fund a portion of the Company’s obligations with respect to the TPG/CalSTRS liquidation. The loan funded on September 27, 2013, in the amount of $80 million. The net proceeds were $78.8 million after payment of loan fees of $1.2 million. The loan bears interest at a rate of 6% per annum for the first six months, 8% per annum for the following six months, and 12% per annum thereafter, with interest payable monthly in arrears. The loan will mature on January 15, 2015. The loan may be prepaid at any time without penalty. The loan agreement contains affirmative and negative covenants, including covenants that restrict the Company’s ability to create liens on its properties, incur additional indebtedness, and engage in mergers, consolidations or sales of all or substantially all of its assets, in each case, subject to specified exceptions.

(3) The mortgage loan is subject to interest only payments through March 5, 2018, and thereafter, principal and interest payments are due based on a thirty-year amortization schedule. The loan may be defeased, and is subject to yield maintenance payments for any prepayments made 60 days prior to the maturity date.
