Item 2.01. Completion of Acquisition or Disposition of Assets.

      On April 30, 2006, Franklin Street Properties Corp. ("FSP Corp."), five of
its wholly-owned subsidiaries (the "Acquisition Subsidiaries") and five real
estate investment trusts (the "Target REITs"), consummated the acquisition of
the Target REITs by FSP Corp. by means of the merger of each Target REIT with
and into an Acquisition Subsidiary ("the Mergers"), pursuant to the Agreement
and Plan of Merger dated as of March 15, 2006 (the "Merger Agreement"). The
Target REITs are FSP Willow Bend Office Center Corp., FSP Innsbrook Corp., FSP
380 Interlocken Corp., FSP Blue Lagoon Drive Corp., and FSP Eldridge Green Corp.
The Acquisition Subsidiaries are Willow Bend Acquisition Corp., Innsbrook
Acquisition Corp., 380 Interlocken Acquisition Corp., Blue Lagoon Acquisition
Corp., and Eldridge Green Acquisition Corp. FSP Willow Bend Office Center Corp.
owned an office building in Plano, Texas; FSP Innsbrook Corp. owned three office
buildings in Glen Allen, Virginia; FSP 380 Interlocken Corp. owned an office
building in Broomfield, Colorado; FSP Blue Lagoon Drive Corp. owned an office
building in Miami, Florida; and FSP Eldridge Green Corp. owned an office
building in Houston, Texas.

      Pursuant to the Merger Agreement, the preferred stock in each Target REIT
(the "Target Stock") was converted into a number of shares of FSP Corp. common
stock equal to an exchange ratio, which exchange ratio was calculated for each
Target REIT by dividing the price per share of the Target REIT by the market
value of the FSP Corp. common stock. The market value of FSP Corp. common stock
was $20.94 per share calculated by taking the volume weighted average of the
selling price of the FSP Corp. common stock on the American Stock Exchange over
twenty (20) consecutive trading days commencing on March 29, 2006 and ending on
April 26, 2006. Under generally accepted accounting principles in the United
States, FSP Corp. is reporting the market value of FSP Corp. common stock at
$21.01 per share, as further described in the Notes to Condensed Consolidated
Pro Forma Financial Statements included with this Current Report on Form 8-K.
The price per share of each Target REIT is set forth in the table below:

      Target REIT                        Price Per Target Share
      -----------                        ----------------------
      Willow Bend                        $100,000.00
      Innsbrook                          $105,263.16
      380 Interlocken                    $105,000.00
      Blue Lagoon                        $100,000.00
      Eldridge Green                     $121,546.96



Based on the above-described exchange ratio, the Target Stock was converted into
the number of shares of common stock of FSP Corp. set forth in the table below
and FSP Corp. has reserved for issuance an aggregate of 10,972,279 shares. In
addition, the one share of common stock issued and outstanding for each Target
REIT, and held by FSP Corp., was cancelled. FSP Corp. did not receive any
consideration for the one share of common stock it held in each Target REIT or
for the 49.25 shares of preferred stock it held in FSP Blue Lagoon Drive Corp.

                                    FSP Corp. issuable in         FSP Corp. issuable in the
                                   exchange for each share      aggregate to stockholders of
      Target REIT                      of Target Stock             each Target REIT (1)(2)

      Willow Bend                         4,775.55                          938,763
      Innsbrook                           5,026.89                        2,387,775
      380 Interlocken                     5,014.33                        2,406,877
      Blue Lagoon                         4,775.55                        2,625,358

                                                                         ----------
      Total                                                              10,972,279
                                                                         ==========


----------
(1)   Rounded to the nearest whole share.
(2)   This number of shares of common stock of FSP Corp. is slightly higher than
      the actual number of shares of common stock of FSP Corp. issued in
      connection with the Mergers due to the fact that FSP Corp. will pay cash
      in lieu of issuing fractional shares of common stock of FSP Corp.

      The Merger Agreement was approved by the board of directors of FSP Corp.
and the board of directors and a majority of the stockholders of each Target
REIT. A number of conflicts of interest are inherent in the relationships among
the Target REITs, the boards of directors of the Target REITs, FSP Corp., FSP
Corp.'s board of directors and their respective affiliates. These conflicts of
interest include, among others:

o     George J. Carter, the President and a director of each Target REIT, is
      President and Chief Executive Officer and a director of FSP Corp. and owns
      an aggregate of 810,531 shares of common stock of FSP Corp.;

o     R. Scott MacPhee, an Executive Vice President, a director of each Target
      REIT and a member of the special committee of each Target REIT's board of
      directors, is also an Executive Vice President of FSP Corp. and owns an
      aggregate of 386,451 shares of common stock of FSP Corp.;

o     William W. Gribbell, an Executive Vice President, a director of each
      Target REIT and a member of the special committee of each Target REIT's
      board of directors, is also an Executive Vice President of FSP Corp. and
      owns an aggregate of 131,212 shares of common stock of FSP Corp.;

o     Barbara J. Fournier, Vice President, Chief Operating Officer, Treasurer,
      Secretary and a director of each Target REIT, is also Vice President,
      Chief Operating Officer, Treasurer, Secretary and a director of FSP Corp.
      and owns an aggregate of 28,934 shares of common stock of FSP Corp.;

o     Janet P. Notopoulos, Vice President of each target REIT and a director of
      FSP Blue Lagoon Drive Corp. and FSP Eldridge Green Corp., is also a Vice
      President and director of FSP Corp. and owns an aggregate of 14,985 shares
      of common stock of FSP Corp.; and


o     Barry Silverstein, Dennis J. McGillicuddy, John N. Burke and Georgia
      Murray, are the only directors of FSP Corp. who are not also officers or
      directors of any Target REIT.

      Mr. Silverstein and Mr. McGillicuddy, each a director of FSP Corp.,
beneficially owned an aggregate of 102.5 and 33 shares of Target Stock,
respectively. Messrs. Silverstein and McGillicuddy each purchased their shares
in the original offerings of Target Stock and on the same terms as other
stockholders of such Target REITs. These shares of Target Stock held by Messrs.
Silverstein and McGillicuddy converted into approximately 535,346 and
approximately 157,593 shares of common stock of FSP Corp., respectively.

      The spouse of William Gribbell, an executive officer of FSP Corp. and an
executive officer and a director of each Target REIT, owned 0.25 shares of
Target Stock. Mr. Gribbell's spouse purchased her partial share of Target Stock
in the original offering of Target Stock and, except for not paying a sales
commission, on the same terms as other stockholders of such Target REITs. This
partial share of Target Stock held by Mr. Gribbell's spouse converted into
approximately 1,451 shares of common stock of FSP Corp.

      The properties formerly owned by the Target REITs continue to be managed
by FSP Property Management LLC, a wholly-owned subsidiary of FSP Corp. pursuant
to management services agreements under which FSP Corp. previously received
certain fees from each Target REIT for its management services.
