            SELECTED PRO FORMA COMBINING CONSOLIDATED FINANCIAL DATA

      The following unaudited pro forma financial information gives effect to
the acquisition of the Target REITs by four wholly-owned acquisition
subsidiaries of FSP Corp., which was consummated on April 30, 2005.

      The unaudited pro forma financial information has been prepared based upon
certain pro forma adjustments to the historical consolidated financial
statements of FSP Corp. and the Target REITs. The pro forma consolidated balance
sheets have been presented as if the mergers occurred as of December 31, 2004.
The pro forma consolidated statements of income for the year ended December 31,
2004 and the consolidated pro forma statements of cash flow for the year ended
December 31, 2004 are presented as if the mergers occurred at the beginning of
the period presented.

      Certain balances in 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
financial statements of FSP Corp. and the Target REITs and should be read in
conjunction with those financial statements and the accompanying notes and
"Management's Discussion and Analysis of Financial Information and Results of
Operations," all of which are included in this Current Report on Form 8-K, in
FSP Corp.'s Annual Report on Form 10-K for the year ended December 31, 2004, or
in FSP Corp.'s Registration Statement on Form S-4 (No. 333-118748).

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

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

BASIS OF PRESENTATION

      On April 30, 2005, each of four wholly-owned subsidiaries of FSP Corp.
acquired a Target REIT by merger. The following unaudited pro forma condensed
consolidated financial statement presentation has been prepared based upon
certain pro forma adjustments to the historical consolidated financial
statements of FSP Corp. The pro forma balance sheets are presented as if the
mergers occurred as of December 31, 2004. The pro forma statements of income and
the pro forma statements of cash flow are presented as if the mergers occurred
as of the beginning of the periods presented.

      The mergers will be treated as a purchase of assets and each Target REIT's
assets and liabilities will be recorded on FSP Corp.'s books at their fair value
as of the effective date of the mergers, which was April 30, 2005. The value
ascribed to the net assets of the target REITs is estimated to be $156,739,000,
which includes real estate assets of $149,075,000 at their appraised values,
cash of $6,664,000 and capitalized merger costs of $1,000,000. Other assets, net
of liabilities, are expected to be immaterial. FSP Corp. will record the mergers
based upon the fair value of the assets acquired, not the value of the shares of
FSP Corp.'s common stock issued. The value allocated to the assets acquired in
the mergers is preliminary; the final value allocated to the assets acquired
is subject to change as additional information is obtained.

PRO FORMA ADJUSTMENTS

      Certain assumptions regarding the operations of FSP Corp. have been made
in connection with the preparation of the pro forma condensed consolidated
financial 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)   Costs of the mergers to the Target REITs are estimated at $507,000
            and are reflected as paid at December 31, 2004, and are recorded as
            an administrative expense. Costs of $352,000 were previously
            recorded as administrative expenses in 2004 and an additional
            $155,000 is estimated to complete the merger.

      (c)   The costs of the mergers to FSP Corp. are estimated at $1,000,000
            and are reflected as paid as of December 31, 2004 and are
            capitalized to the assets acquired. Costs of $447,000 were
            previously recorded as other assets in 2004 and an additional
            $553,000 is estimated to complete the merger.

      (d)   The following schedule shows the merger consideration for the
            acquired properties and is reconciled to the purchase price of such
            properties (which is equal to the appraised value of such property
            plus capitalized merger costs attributable to such property).

                                      ======================================================================


      The cost of the property held by each Target REIT (including capitalized
merger costs of $1,000,000) has been allocated to real estate assets, acquired
lease origination costs and acquired favorable or unfavorable leases. Acquired
lease origination costs represent the value associated with acquiring an
in-place lease (i.e. the market cost to execute a similar lease, including
leasing commission, legal, vacancy and other related costs). Acquired favorable
or unfavorable leases represents the value associated with a lease which has a
rental stream with above or below market rates. The value assigned to buildings,
land and leases approximates their fair value.

      The following schedule shows the difference between historical costs of
the properties and their allocated purchase price. The purchase price of the
properties is determined based upon the fair value of the assets acquired.
Depreciation and amortization for the Target REITs is based on a preliminary
allocation of the purchase price to real estate investments and to the leases
acquired. The allocation is subject to change as additional information is
obtained. An increase in the value allocated to leases will result in an
increase in amortization. For each $1,000,000 increase in the value allocated to
leases, the related pro forma amortization will increase by approximately
$325,000 per year.

      (i)   FSP Corp. purchased the real estate assets and a stated amount of
            cash (the adjusted cash reserves) from each Target REIT in exchange
            for a fixed number of shares of FSP common stock. The final dividend
            to the shareholders of the Target REITs represents the estimated
            amount of cash in excess of the stated amount of cash and assuming
            settlement of certain current assets and liabilities as of the date
            of the pro forma balance sheet. The estimated final dividend as of
            the date of the pro forma balance sheet for the Target REITs is
            shown in the following table. The actual final dividend will be
            based upon the amount of cash in excess of the stated amount of cash
            and assuming settlement of certain current assets and liabilities as
            of the actual merger date.

            FSP Corp. and each of the Target REITs on a historical basis.

      (b)   Consolidated pro forma basic and diluted net income per share, book
            value per share and dividends per share for FSP Corp. This table
            shows the effect of the mergers from the perspective of an owner of
            one share of FSP common stock.

      (c)   Equivalent pro forma basic and diluted net income per share,
            equivalent pro forma book value per share and equivalent pro forma
            dividends per share for each of the Target REITs. This table shows
            the effect of the mergers from the perspective of an owner of one
            share of stock of a Target REIT. The consolidated pro forma data are
            multiplied by the number of shares of FSP common stock issuable in
            exchange for each share of target stock, also known as the exchange
            ratio, as shown in the following table:
