Item 2.01.  Completion of Acquisition or Disposition of Assets.

      On June 27, 2006, FSP One Overton Park LLC (the "Purchaser"), a
wholly-owned subsidiary of Franklin Street Properties Corp. (the "Registrant"),
consummated the acquisition of a fifteen-story Class A office property located
at 3625 Cumberland Boulevard in Atlanta, Georgia (the "Property"). The Property
is known as "One Overton Park" and contains approximately 390,000 rentable
square feet of space. The Purchaser acquired the Property from One Overton Park
LLC (the "Seller"). There are no material relationships, other than in respect
of the purchase of the Property, among the Purchaser, the Seller, the Registrant
or any of the Registrant's affiliates, or any director or officer of the
Registrant, or any associate of any such director or officer. The purchase price
for the Property was $85,000,000 and was paid in cash on the closing date.
Neither the Purchaser nor the Registrant incurred any mortgage indebtedness to
purchase the Property; instead, the purchase was funded entirely from the
proceeds of three (3) property sales disclosed in the Registrant's Current
Report on Form 8-K filed with the Securities and Exchange Commission on June 1,
2006.
