News Release Details

BOSTON, MA, October 18, 1999- Boston Properties, Inc. (NYSE:BXP), a real estate investment trust, announced today that its Washington, DC Regional Office has made a $10,000 donation to the Thurgood Marshall Center for Service and Heritage. The Center is located in a National Historic Landmark building in the Shaw neighborhood of Washington, DC, that will house the Shaw Heritage Trust and the For Love of Children organization. Together, these organizations are renovating the Thurgood Marshall Center for Service and Heritage, and will be its major tenants upon completion of the construction.

The Shaw Heritage Trust is a non-profit group dedicated to preserving the history of the Shaw area. For Love of Children, also non-profit, is a provider of educational and recreational programs, foster care, youth leadership training and transitional housing, and has been active in the Shaw community for 35 years.

The Thurgood Marshall Center was designed in the early 1900's by one of America's first African-American architects, W. Sidney Pittman, son-in-law of Booker T. Washington. President Theodore Roosevelt laid the cornerstone of the building in 1912. The building was formerly the first full-service African-American YMCA, and served as an important part of African-American community life in Washington, DC. The Shaw Heritage Trust and For Love of Children have been determined to renovate this important building since it closed in 1982. The structure was named a National Historic Landmark in 1994 and a National Historic Treasure in early 1999. Renovations began in September 1998 and occupancy is expected in January 2000.

Mitch Norville, Boston Properties' Senior Vice President and Operations Manager of the Washington, DC office, said, "The renovation of the Thurgood Marshall Center for Service and Heritage not only gives an older building new life, it gives a community center back to the Shaw neighborhood. Boston Properties is pleased to make a donation toward this project."

Thurgood Marshall Center Trust President Norris A. Dodson III stated, "We are pleased that Boston Properties supports our vision and shares in the excitement of a new neighborhood collaborative that will serve as a model for the District of Columbia and other urban areas. Future generations will benefit greatly from the preservation of this building and its rich history."
