Exhibit 99.2


       SELECTED COMBINING CONDENSED CONSOLIDATED PRO FORMA FINANCIAL DATA

      The following unaudited pro forma financial information of Franklin Street
Properties Corp. ("FSP Corp." or the "Registrant") gives effect to the
acquisition of a property ("One Overton Park") on June 27, 2006 by FSP One
Overton Park LLC (the "Purchaser"), a wholly-owned subsidiary of FSP Corp. and
the acquisition by merger (the "2006 Merger") of FSP Willow Bend Office Center
Corp. ("Willow Bend"), FSP Innsbrook Corp. ("Innsbrook"), FSP 380 Interlocken
Corp. ("380 Interlocken"), FSP Blue Lagoon Drive Corp. ("Blue Lagoon"), and FSP
Eldridge Green Corp. ("Eldridge") (collectively, the "Target REITs") by five
wholly-owned acquisition subsidiaries of FSP Corp., which was consummated on
April 30, 2006 and previously reported in Current Reports on Form 8-K filed on
May 4, 2006 and May 22, 2006. In addition, the following unaudited pro forma
financial information gives effect to the 2005 Merger (as defined in note (g) to
these Combining Condensed Consolidated Pro Forma Statements of Income).

      The unaudited pro forma financial information has been prepared based upon
certain pro forma adjustments to the historical consolidated financial
statements of FSP Corp., One Overton Park and the Target REITs. FSP Corp.'s
consolidated balance sheet as of June 30, 2006 reflects the acquisition of One
Overton Park and the Target REITs; therefore a pro forma balance sheet is not
presented. The pro forma consolidated statements of income for the six months
ended June 30, 2006 and for the year ended December 31, 2005 are presented as if
the acquisitions occurred at the beginning of the periods presented.

      Certain balances in One Overton Park and the Target REIT financial
statements have been reclassified to conform to FSP Corp.'s presentation.

      The unaudited pro forma financial information has been derived from the
consolidated financial statements of FSP Corp., One Overton Park and the Target
REITs and should be read in conjunction with those financial statements and the
accompanying notes. For FSP Corp., please refer to its quarterly report on Form
10-Q for the quarter ended June 30, 2006.

      The unaudited pro forma consolidated financial statement data are not
necessarily indicative of what the actual financial position or results of
operations of the combined companies would have been as of the date or for the
period indicated, nor do they purport to represent the financial position or
results of operations of the combined companies as of or for any future period.

                        FRANKLIN STREET PROPERTIES CORP.
    NOTES TO COMBINING CONDENSED CONSOLIDATED PRO FORMA FINANCIAL STATEMENTS
                                   (Unaudited)

BASIS OF PRESENTATION

      The following unaudited combining condensed consolidated pro forma
financial statement presentation has been prepared based upon certain pro forma
adjustments to the historical consolidated financial statements of FSP Corp. The
pro forma statements of income are presented as if the acquisition and mergers
occurred as of the beginning of the periods presented.

      Each of the acquisition of One Overton Park on June 27, 2006 and the 2006
Merger has been treated as a purchase of assets. One Overton Park and the Target
REITs' assets and liabilities have been recorded on FSP Corp.'s books at their
fair value as of the effective date of the mergers as determined in accordance
with generally accepted accounting principles in the United States (or "GAAP").

PRO FORMA ADJUSTMENTS

      Certain assumptions regarding the operations of FSP Corp. have been made
in connection with the preparation of the combining condensed consolidated
financial pro forma information. These assumptions are as follows:

      (a)   FSP Corp. and each of the Target REITs have elected to be, and are
            qualified as, a real estate investment trust for federal income tax
            purposes. Each entity has met the various required tests; therefore,
            no provision for federal or state income taxes has been reflected on
            real estate operations.

            FSP Corp. has subsidiaries which are not in the business of real
            estate operations. Those subsidiaries are taxable as real estate
            investment trust subsidiaries, or TRS, and are subject to income
            taxes at statutory tax rates. The taxes on income shown in the pro
            forma statements of income are the taxes on income of the TRS. There
            are no material items that would cause a deferred tax asset or a
            deferred tax liability.

      (b)   The pro forma adjustments reflect the adjustments needed to classify
            the operations of three properties sold or held for sale subsequent
            to December 31, 2005 as discontinued operations.
