The reported results are unaudited and there can be no assurance that the results will not vary from the final information for the quarter and year ended December 31, 2005. In the opinion of management, all adjustments considered necessary for a fair presentation of these reported results have been made.

As of December 31, 2005, the Company's portfolio consisted of 121 properties comprising approximately 42.0 million square feet, including three properties under construction and one expansion project totaling 1.1 million square feet. The overall percentage of leased space for the 116 properties in service as of December 31, 2005 was 93.8%.

Significant events of the fourth quarter include:

  • On October 4, 2005, the Company repaid the mortgage loan collateralized by its Embarcadero Center West Tower property located in San Francisco, California totaling approximately $90.7 million using approximately $72.7 million of available cash and $18.0 million drawn under the Company's Unsecured Line of Credit. There was no prepayment penalty associated with the repayment.
  • On November 4, 2005, the Company sold the Residence Inn by Marriott(R), a 221-room extended-stay hotel property located in Cambridge, Massachusetts, at a gross sale price of approximately $68.0 million, less closing costs and a credit of approximately $3.0 million representing the property-controlled furniture, fixtures and equipment escrow funds set aside for planned property upgrades.
  • On November 7, 2005, the Company sold 40-46 Harvard Street, an industrial property with approximately 152,000 net rentable square feet located in Westwood, Massachusetts, at a sale price of approximately $7.8 million.
  • On December 14, 2005, the Company sold Embarcadero Center West Tower, a Class A office property with approximately 475,000 net rentable square feet located in San Francisco, California, at a gross sale price of approximately $205.8 million, less customary closing costs, transaction-related expenses and unfunded tenant obligations totaling approximately $10.6 million.
  • On December 14, 2005, the joint venture entity that is developing 505 9th Street in Washington, D.C. closed on a collateralized, construction-to-permanent financing totaling $95.0 million. The construction financing is comprised of a $60.0 million loan commitment, which bears interest at a fixed rate of 5.73% per annum, and a $35.0 million loan commitment, which bears interest at a variable rate equal to LIBOR plus 1.25% per annum. The construction financing converts to a ten-year fixed rate loan in October 2007, subject to the satisfaction of certain operating performance and financial measures, at an interest rate of 5.73% per annum with a provision for an increase in the borrowing capacity by $35.0 million (which would bring the total available financing to $130.0 million).
  • On December 20, 2005, the Company's Value-Added Fund acquired 300 Billerica Road, a 111,000 net rentable square foot office property, located in Chelmsford, Massachusetts, at a purchase price of approximately $10.0 million. The acquisition was financed with new mortgage indebtedness totaling $7.5 million and approximately $2.5 million in cash, of which the Company's share was approximately $0.6 million. The mortgage financing bears interest at a fixed rate of 5.69% per annum and matures on January 1, 2016.
  • On December 30, 2005, the Company acquired Prospect Place, a Class A office property with approximately 297,000 net rentable square feet located in Waltham, Massachusetts, at a purchase price of approximately $62.8 million. The acquisition was financed with available cash. Prospect Place is currently 67% leased with an average rental rate that is below market. The Company projects this property's 2006 Unleveraged FFO Return to be 4.7% and 2006 Unleveraged Cash Return to be 3.4%. Assuming the Company leases substantially all of the currently available space at market rates by 2008 and spends approximately $8.8 million for improvements and leasing commissions, the Company projects stabilized Unleveraged FFO Return to be 8.7% and stabilized Unleveraged Cash Return to be 7.9%. The calculation of these returns and related disclosures are presented on the accompanying table entitled "Projected 2006 & Stabilized Returns on Acquisition." There can be no assurance that actual returns will not differ materially from these projections.
  • On December 30, 2005, the Company repaid at maturity the mortgage loan collateralized by its 601 & 651 Gateway Boulevard properties located in South San Francisco, California, totaling approximately $85.7 million.
  • During the fourth quarter 2005, the Company continued its planned interest rate hedging program. As of December 31, 2005, the Company had entered into forward-starting interest rate swap contracts which fix the ten-year treasury rate for financings in early 2007 at a weighted-average rate of 4.34% per annum on notional amounts aggregating $500.0 million, which go into effect in February 2007 and expire in February 2017. The Company entered into the interest rate swap contracts designated and qualifying as cash flow hedges to reduce its exposure to the variability in future cash flows attributable to changes in the Treasury rate in contemplation of obtaining ten-year fixed-rate financing in early 2007.
Transactions completed subsequent to December 31, 2005:
  • During January 2006, the Company placed-in-service its Seven Cambridge Center development project located in Cambridge, Massachusetts. Seven Cambridge Center is a fully-leased, build-to-suit project with approximately 231,000 square feet of office, research laboratory and retail space. The Company has leased 100% of the space to the Massachusetts Institute of Technology for occupancy by its affiliate, the Eli and Edythe L. Broad Institute. On October 1, 2005, the Company had placed-in-service the West Garage phase of the project consisting of parking for approximately 800 cars.

    (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
        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.

        In addition to presenting FFO in accordance with the NAREIT
        definition, we also disclose FFO after a specific and defined
        supplemental adjustment to exclude losses from early extinguishments
        of debt associated with the sales of real estate.  The adjustment to
        exclude losses from early extinguishments of debt results when the
        sale of real estate encumbered by debt requires us to pay the
        extinguishment costs prior to the debt's stated maturity and to write-
        off unamortized loan costs at the date of the extinguishment.  Such
        costs are excluded from the gains on sales of real estate reported in
        accordance with GAAP.  However, we view the losses from early
        extinguishments of debt associated with the sales of real estate as an
        incremental cost of the sale transactions because we extinguished the
        debt in connection with the consummation of the sale transactions and
        we had no intent to extinguish the debt absent such transactions.  We
        believe that this supplemental adjustment more appropriately reflects
        the results of our operations exclusive of the impact of our sale
        transactions.

        Although our FFO as adjusted clearly differs from NAREIT's definition
        of FFO, and may not be comparable to that of other REITs and real
        estate companies, we believe it provides a meaningful supplemental
        measure of our operating performance because we believe that, by
        excluding the effects of the losses from early extinguishments of debt
        associated with the sales of real estate, management and investors are
        presented with an indicator of our operating performance that more
        closely achieves the objectives of the real estate industry in
        presenting FFO.

        Neither FFO nor FFO as adjusted should be considered as an alternative
        to net income (determined in accordance with GAAP) as an indication of
        our performance.  Neither FFO nor FFO as adjusted 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 and FFO as adjusted 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
        $66,290, $68,342, $266,829 and $249,649, our share of unconsolidated
        joint venture real estate depreciation and amortization of $2,174,
        $1,798, $8,554 and $6,814 and depreciation and amortization from
        discontinued operations of $63, $393, $812 and $3,292, less corporate
        related depreciation and amortization of $540, $544, $1,719 and $2,436
        for the three months and year ended December 31, 2005 and 2004,
        respectively.

      Unleveraged Cash Return (2)                      3.4%              7.9%



    (1) Unleveraged FFO Return is determined by dividing the Unleveraged FFO
        (based on the projected results for either the year ending December
        31, 2006 or stabilized results) 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 either the year ending
        December 31, 2006 or stabilized results) 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.
