The reported results are unaudited and there can be no assurance that the results will not vary from the final information for the quarter ended March 31, 2007. In the opinion of management, all adjustments considered necessary for a fair presentation of these reported results have been made.

As of March 31, 2007, the Company's portfolio consisted of 135 properties comprising approximately 42.9 million square feet, including six properties under construction totaling 1.4 million square feet and one hotel. The overall percentage of leased space for the 128 properties in service as of March 31, 2007 was 93.8%.

Significant events of the first quarter include:

  • In January 2007, the Company acquired 6601 and 6605 Springfield Center Drive, consisting of two office/technical properties aggregating approximately 97,000 net rentable square feet located in Springfield, Virginia for an aggregate purchase price of approximately $16.5 million. On April 11, 2007, the Company acquired an additional adjacent parcel of land for a purchase price of approximately $25.6 million. The combined properties will support future development of approximately 800,000 net rentable square feet.
  • In January 2007, the Company acquired parcels of land located at 250 West 55th Street in New York City, through a majority-owned venture, for an aggregate purchase price of approximately $228.8 million. The Company also has agreements to acquire other real estate interests, for approximately $33.1 million. The acquisitions were financed with members' capital contributions and a $160.0 million mortgage loan bearing interest at a variable rate equal to LIBOR plus 0.40% per annum and maturing in January 2009. The assembled land parcels will support the development of an approximately 975,000 net rentable square foot Class A office tower. On February 26, 2007, the Company entered into an agreement to acquire the outside member's equity interest in the venture for approximately $23.4 million.
  • On January 29, 2007, the Company acquired 103 Fourth Avenue, an approximately 62,000 net rentable square foot office/technical property located in Waltham, Massachusetts, for a purchase price of approximately $14.3 million. The property is adjacent to other recently acquired land parcels that once assembled will support future development.
  • On February 6, 2007, the Company's Operating Partnership completed an offering of $862.5 million in aggregate principal amount (including $112.5 million as a result of the exercise by the initial purchasers of their over-allotment option) of its 2.875% exchangeable senior notes due 2037. The notes were priced at 97.433% of their face amount, resulting in an effective interest rate of approximately 3.438% per annum and net proceeds to the Company of approximately $840.0 million. The notes mature on February 15, 2037, unless earlier repurchased, exchanged or redeemed. The notes may be exchanged prior to the close of business on the scheduled trading day immediately preceding February 20, 2012 into cash and, at the Operating Partnership's option, shares of the Company's common stock at an initial exchange rate of 6.6090 shares per $1,000 principal amount of notes (or an initial exchange price of approximately $151.31 per share of the Company's common stock). The notes were issued in an offering exempt from registration under the Securities Act of 1933. On March 13, 2007, the Company filed with the SEC a registration statement covering the resale of the notes and of shares of common stock issuable upon exchange of the notes, which was declared effective by the SEC on April 20, 2007.
  • On February 12, 2007, the Company refinanced its mortgage loan collateralized by 599 Lexington Avenue located in New York City. The new mortgage financing totaling $750.0 million bears interest at a fixed interest rate of 5.57% per annum and matures on March 1, 2017. On December 19, 2006, the Company had terminated its forward-starting interest rate swap contracts and received approximately $10.9 million, which amount will reduce the Company's interest expense over the ten- year term of the financing, resulting in an effective interest rate of 5.38% per annum for the financing. The Company used a portion of the net proceeds to repay the $225.0 million drawn on its Unsecured Line of Credit, which draw was collateralized by 599 Lexington Avenue. In addition, the Company used the net proceeds from the refinancing to repay the mortgage loan collateralized by Times Square Tower located in New York City totaling $475.0 million. The Times Square Tower mortgage loan bore interest at a variable rate equal to LIBOR plus 0.50% per annum and was scheduled to mature on July 9, 2008. There was no prepayment penalty associated with the repayment.
  • On February 15, 2007, the Company completed the sale of its long-term leasehold interest in 5 Times Square in New York City and related credits, for approximately $1.28 billion in cash, or approximately $1,160 per square foot. 5 Times Square is a fully-leased Class A office tower that contains 1,101,779 net rentable square feet. 5 Times Square was developed by the Company in 2002 at a total cost of approximately $490 million.
  • On March 9, 2007, the Company's Value-Added Fund executed a binding agreement for the sale of Worldgate Plaza located in Herndon, Virginia, for approximately $109.0 million. Worldgate Plaza is an office complex consisting of approximately 322,000 net rentable square feet. The sale is subject to the satisfaction of customary closing conditions and, although there can be no assurance that the sale will be consummated on the terms currently contemplated or at all, it is expected to close by the end of the second quarter of 2007.
  • On March 23, 2007, the Company completed the sale of the Long Wharf Marriott, a 402-room hotel located in Boston, Massachusetts for a total sale price of $231.0 million, or approximately $575,000 per room.
  • On March 30, 2007, the Company acquired Kingstowne Towne Center, a mixed-use property located in Alexandria, Virginia, at a purchase price of approximately $134.0 million. This property is comprised of two Class A office properties totaling approximately 307,000 net rentable square feet and a retail/movie theater complex totaling approximately 88,000 net rentable square feet. The acquisition was financed with the assumption of mortgage indebtedness totaling $65.3 million and available cash. The assumed mortgage financing consists of two mortgage loans of $44.9 million and $20.4 million, which bear interest at fixed rates of 5.99% and 5.96% per annum and mature on January 1, 2016 and May 5, 2013, respectively. The Company projects this property's annualized 2007 Unleveraged FFO Return to be 7.9% and annualized 2007 Unleveraged Cash Return to be 6.8%. The Company projects this property's 2008 Unleveraged FFO Return to be 8.1% and 2008 Unleveraged Cash Return to be 7.2%. The calculation of these returns and related disclosures are presented on the accompanying table entitled "Projected 2007 and 2008 Returns on Acquisition." There can be no assurance that actual returns will not differ materially from these projections.
  • On March 30, 2007, the Company acquired Russia Wharf, a land parcel located in Boston, Massachusetts, for a purchase price of approximately $105.5 million. The land parcel will support a mixed-use development of approximately 775,000 net rentable square feet, anchored by office space.
  • During the three months ended March 31, 2007, the Company signed a new qualifying lease for approximately 22,000 net rentable square feet of its remaining 47,659 net rentable square foot master lease obligation related to the sale of 280 Park Avenue resulting in the recognition of approximately $18.0 million as additional gain on sale of real estate. The Company had deferred approximately $67.3 million of the gain on sale of 280 Park Avenue, which amount represented the maximum obligation under the master lease. As of March 31, 2007, the master lease obligation totaled approximately $27.4 million.

Transactions completed subsequent to March 31, 2007:

  • On April 5, 2007, the Company sold Newport Office Park located Quincy, Massachusetts, for approximately $37.0 million. Newport Office Park is a Class A office property consisting of approximately 172,000 net rentable square feet.

     (1) Pursuant to the revised definition of Funds from Operations adopted
         by the Board of Governors of the National Association of Real Estate
         Investment Trusts ("NAREIT"), we calculate Funds from Operations, or
         "FFO," by adjusting net income (loss) (computed in accordance with
         GAAP, including non-recurring items) for gains (or losses) from sales
         of properties, real estate related depreciation and amortization, and
         after adjustment for unconsolidated partnerships and joint ventures.
         FFO is a non-GAAP financial measure.  The use of FFO, combined with
         the required primary GAAP presentations, has been fundamentally
         beneficial in improving the understanding of operating results of
         REITs among the investing public and making comparisons of REIT
         operating results more meaningful.  Management generally considers
         FFO to be a useful measure for reviewing our comparative operating
         and financial performance because, by excluding gains and losses
         related to sales of previously depreciated operating real estate
         assets and excluding real estate asset depreciation and amortization
         (which can vary among owners of identical assets in similar condition
         based on historical cost accounting and useful life estimates), FFO
         can help one compare the operating performance of a company's real
         estate between periods or as compared to different companies.  Our
         computation of FFO may not be comparable to FFO reported by other
         REITs or real estate companies that do not define the term in
         accordance with the current NAREIT definition or that interpret the
         current NAREIT definition differently.

         FFO should not be considered as an alternative to net income
         (determined in accordance with GAAP) as an indication of our
         performance.  FFO does not represent cash generated from operating
         activities determined in accordance with GAAP and is not a measure of
         liquidity or an indicator of our ability to make cash distributions.
         We believe that to further understand our performance, FFO should be
         compared with our reported net income and considered in addition to
         cash flows in accordance with GAAP, as presented in our consolidated
         financial statements.

     (2) Real estate depreciation and amortization consists of depreciation
         and amortization from the Consolidated Statements of Operations of
         $70,478 and $66,005, our share of unconsolidated joint venture real
         estate depreciation and amortization of $2,099 and $2,304 and
         depreciation and amortization from discontinued operations of $608
         and $842, less corporate related depreciation and amortization of
         $315 and $477 for the three months ended March 31, 2007 and 2006,
         respectively.

     (3) Excludes an adjustment of approximately $3.1 million for the three
         months ended March 31, 2007 to the income allocated to the holders of
         Series Two Preferred Units to account for their right to participate
         on an as-converted basis in the special dividend that followed
         previously completed sales of real estate.

      Unleveraged FFO Return (1)                      7.9%              8.1%

      Unleveraged Cash Return (2)                     6.8%              7.2%


     (1) Unleveraged FFO Return is determined by dividing the Unleveraged FFO
         (based on the projected results for the nine months ending December
         31, 2007 (annualized) and the year ending December 31, 2008) by Total
         Investment.  Other real estate companies may calculate this return
         differently.  Management believes projected Unleveraged FFO Return is
         a useful measure in the real estate industry when determining the
         appropriate purchase price for a property or estimating a property's
         value.  When evaluating acquisition opportunities, management
         considers, among other factors, projected Unleveraged FFO Return
         because it excludes, among other items, interest expense (which may
         vary depending on the level of corporate debt or property-specific
         debt), as well as depreciation and amortization expense (which can
         vary among owners of identical assets in similar condition based on
         historical cost accounting and useful life estimates).  In addition,
         management considers its cost of capital and available financing
         alternatives in making decisions concerning acquisitions.

     (2) Unleveraged Cash Return is determined by dividing the Unleveraged
         Cash (based on the projected results for the nine months ending
         December 31, 2007 (annualized) and the year ending December 31, 2008)
         by Total Investment.  Other real estate companies may calculate this
         return differently.  Management believes that projected Unleveraged
         Cash Return is also a useful measure of a property's value when used
         in addition to Unleveraged FFO Return because, by eliminating the
         effect of straight-lining of rent and the SFAS No. 141 treatment of
         in-place above- and below-market leases, it enables an investor to
         assess the cash on cash return from the property over the forecasted
         period.

         Management is presenting these projected returns and related
         calculations to assist investors in analyzing the Company's recent
         acquisition.  Management does not intend to present this data for any
         other purpose, for any other period or for its other properties, and
         is not intending for these measures to otherwise provide information
         to investors about the Company's financial condition or results of
         operations.  The Company does not undertake a duty to update any of
         these projections.
