Item 7.01.  Regulation FD Disclosure

      On November 5, 2007, Franklin Street Properties Corp. (the "Registrant")
committed to acquire up to 994 shares of preferred stock ("Preferred Stock") in
FSP 303 East Wacker Drive Corp. (the "Company") for a total investment of up to
$85,235,500.00 (assuming that the Registrant acquires all 994 shares) upon
satisfaction of certain conditions.

      The Company is a Delaware corporation formed to purchase, own and operate
a 28-story Class "A" multi-tenant office tower containing approximately 859,187
square feet of rentable space located in downtown Chicago, Illinois (the
"Property"). The Company is operated in a manner intended to qualify as a real
estate investment trust for federal income tax purposes. The Company was
organized initially in December 2006 by FSP Investments LLC (member, FINRA and
SIPC), a wholly-owned subsidiary of the Registrant. FSP Investments LLC acted as
a real estate investment firm and broker/dealer with respect to the organization
of the Company and the acquisition of the Property by the Company.

      Holders of Preferred Stock have limited voting rights. The Registrant has
agreed to vote any shares of Preferred Stock held by it on any matter presented
to the holders of Preferred Stock in a manner that approximates as closely as
possible the votes cast in favor of and opposed to such matter by the holders of
the Preferred Stock other than the Registrant. For purposes of determining how
the Registrant votes its shares of Preferred Stock, abstentions and non-votes by
stockholders other than the Registrant are not considered.

      Affiliates of the Registrant currently serve as officers and directors of
the Company but receive no compensation for such service. In addition, the
Registrant holds the sole share of the Company's common stock, which ownership
provides the Registrant with the right to elect all of the Company's directors,
except in limited situations. The Company's directors generally have sole
authority for the operation and management of the Company and the Property.

      The Registrant and its wholly-owned subsidiaries have been paid and will
continue to be paid certain fees by the Company.
