(NYSE: BXP) today reported results for the first quarter ended March 31, 2002. Funds from Operations (FFO) for the quarter ended March 31, 2002, including a $4.3 million write-down of securities, were $88.9 million, or $0.98 per share basic and $0.93 per share diluted before an accounting charge related to the application of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" and after an adjustment for early surrender lease payments received. FFO for the first quarter of 2002 compares to FFO of $79.2 million, or $0.89 per share basic and $0.85 per share diluted for the quarter ended March 31, 2001. This represents a 9.4% quarter to quarter increase in diluted FFO per share. The weighted average number of basic and diluted shares outstanding totaled 90,932,427 and 105,767,653, respectively, for the quarter ended March 31, 2002 and 88,687,900 and 104,160,181, respectively, for the same quarter last year. Income before the charge related to SFAS No. 133, gain on sale of real estate, discontinued operations and cumulative effect of a change in accounting principle and including a $4.3 million write-down of securities totaled $49.2 million or $0.53 per share diluted in the first quarter of 2002 as compared to $49.6 million or $0.54 per share diluted for the same period in 2001. 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, 2002. In the opinion of management, all adjustments considered necessary for a fair presentation of these reported results have been made. As of March 31, 2002, the Company's portfolio consisted of 144 properties comprising more than 41.2 million square feet, including 10 properties under development totaling -MORE-

4.3 million square feet. The overall occupancy rate for the properties in service as of March 31, 2002 was 95.1 %. Additional highlights of the first quarter include: o The completion of the One Discovery Square development project, a 180,052 square foot office building in Reston, Virginia. This project is 100% leased. o The completion of the 5 Times Square development project, a 1,099,154 square foot office building in New York City. This project is approximately 98% leased. o The completion of the ITT Educational Services development project, a 32,000 square foot building in Springfield, Virginia. This project is 100% leased. o The closing on March 8, 2002 of construction financing totaling $24.0 million collateralized by the Shaws Supermarket development project at the Prudential Center in Boston, Massachusetts. Such financing bears interest at a rate of LIBOR + 1.40% and matures in September 2003. o The disposition on March 4, 2002 of Fullerton Square, 7600 Boston Boulevard, 7700 Boston Boulevard and 7702 Boston Boulevard, consisting of five office/technical properties totaling 374,680 square feet in Springfield, Virginia for a net gain of approximately $20.7 million, of which $13.5 million has been deferred. o The write-down of our investment in the securities of Captivate Network, Inc. totaling $4.3 million. o Arthur Andersen LLP has a lease for 620,947 square feet at Times Square Tower. Times Square Tower is a 1.2 million square foot office property that is expected to be completed during 2004. Because of our uncertainty over Arthur Andersen LLP's ultimate space needs, we have begun discussions with them about options ranging from reducing the size of the leased premises to termination of the lease. Meanwhile, we continue to actively market space in the building and are encouraged by the level of interest. o The GSA preleased 100% of New Dominion Technology Park, Building Two, a 257,400 square foot office building to be developed in Herndon, Virginia. The building is expected to open in the second quarter of 2004. o Finnegan Henderson Farabow Garret & Dunner, LLP signed a 251,337 square foot lease to occupy 47% of 901 New York Avenue. Construction will commence in the third quarter of 2002 for occupancy at the end of 2004. This property is owned in partnership with the New York State Common Retirement Fund.
