The building totals 1.1 million sf of space and is leased to tenants such as Independence Investments, Citizens Bank, Salomon Smith Barney and the law firm of Goodwin Procter.

Lease rates for this deal were not available, but the average asking rent for office space in the city's financial district is about $38 per sf, although sublease deals tend to command a lower than average rate.
