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, 2000. In the opinion of management, all adjustments considered necessary for a fair presentation of these reported results have been made. As of December 31, 2000, the Company's portfolio consisted of 144 properties comprising more than 37.6 million square feet, including 15 properties currently under construction totaling 4.5 million square feet. The overall occupancy rate for the properties in service as of December 31, 2000 was 98.9%. Additional highlights of the fourth quarter include: - - The disposition of 1950 Stanford Court, a single story industrial building totaling 53,250 square feet, and an adjacent parcel of land totaling approximately 2 acres in Landover, MD, on October 13, 2000 for approximately $2.2 million. - - The refinancing of the mortgage loan secured by 601 and 651 Gateway which consisted of replacing the $75.0 million mortgage loan with a $90.0 million loan. The new financing bears interest at a rate equal to 8.40% and matures in October 2010. - - The closing on October 6, 2000 of a joint venture with an affiliate of Westbrook, in which Boston Properties has a 50% interest, which was formed to develop One and Two Discovery Square, two Class A office buildings in Reston, Virginia totaling 362,868 square feet. - - The closing of bond financing on October 12, 2000 totaling $57.61 million collateralized by the New Dominion Tech Park, Building One development project in Herndon, Virginia. Such financing matures in October 2020 and bears interest at a rate of 7.58%. The proceeds of $57.61 million were used to fund an escrow and will be held until the New Dominion Tech Park, Building One is completed, which is estimated to be in First Quarter 2001. At that time, it is anticipated that the current construction loan will be paid off and the remaining proceeds will be available to Boston Properties. - - The closing of a public offering on October 31, 2000 of 17,110,000 shares of Common Stock at a price per share of $39.0625 (including 2,110,000 shares issued as a result of the exercise of an overallotment option by the underwriters on November 2, 2000) resulting in net proceeds of approximately $634.1 million. - - The acquisition of the leasehold interest and ground rent credits at One Times Square, future site of Times Square Tower in midtown Manhattan, for approximately $165.1 million on December 1, 2000. This development will consist of a 47-floor, 1.2 million square foot office tower. The office space has been 53% pre-leased to Arthur Andersen.

- - The closing of a construction loan secured by the 40 Shattuck Road development in Andover Office Park, in the amount of $16.0 million at a rate of LIBOR + 1.75% and maturing in December 2003. - - The closing of a construction loan secured by the Discovery Square development in the amount of $75.0 million at a rate of LIBOR + 1.70% and maturing in December 2003.
