(collectively, the "Target REITs") by five wholly-owned acquisition subsidiaries
of FSP Corp., which was consummated on April 30, 2006.

      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 March 31, 2006. The

2006 and the consolidated pro forma statements of cash flow for the three months
ended March 31, 2006 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
consolidated financial statements of FSP Corp. 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 March 31, 2006.

      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 of the combined companies 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 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 balance sheets are presented as if the mergers occurred as of March
31, 2006. 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 as determined in accordance with
generally accepted accounting principles in the United States (or "GAAP").
Pursuant to the Agreement and Plan of Merger dated March 15, 2006 ("Plan of
Merger"), the Company issued 10,971,697 shares of common stock of FSP Corp (or
the "FSP Shares") and paid cash in lieu of issuing 582 FSP Shares, based on a
share price of $20.94, as calculated on April 26, 2006 ("the Measurement Date").
For pro forma presentation, the fair value was calculated in accordance with
GAAP and was measured by the issuance of approximately 10,972,000 shares at a
market price of $21.01 (the "Market Price"), which resulted in total stock
consideration of $230,527,000; plus FSP's Corp's basis in its investment in Blue
Lagoon, which was $4,090,000 as of March 31, 2006; plus $960,000 of capitalized
acquistion costs paid by FSP Corp in connection with the mergers.

      The Market Value of FSP Corp.'s common stock of $21.01 is based on a
volume weighted average price (or "VWAP") as reported by Bloomberg Financial
Markets, which is the average price at which the FSP Shares traded in all
reported public markets, adjusted for the size of each trade. It is calculated
by multiplying the size of every trade by the price, taking the sum of these
values, and then dividing by the total trade volume in all reported public
markets between April 24, 2006 and April 28, 2006. The trades between and
including these dates represent market prices for two days before, the day of,
and two days following the Measurement Date, which occurred prior to the
consummation of the mergers on April 30, 2006.

      The value ascribed to the net assets of the target REITs is estimated to
be $235,577,000, which includes real estate assets of $226,369,000, and net
current assets of $9,208,000 including cash. Other assets, net of liabilities,
are expected to be immaterial. The value allocated to the assets acquired in the
mergers is preliminary and subject to the receipt of additional information,
and is expected to be finalized in the second or third quarter of 2006.

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


                                      P-5


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

            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 $633,000
            and were incurred as of March 31, 2006, and were recorded as an
            administrative expense.

      (c)   The costs of the mergers to FSP Corp. are estimated at $960,000 and
            are capitalized to the assets acquired with $783,000 of the costs
            incurred as of March 31, 2006 and the $177,000 reflected as paid as
            of March 31, 2006.

      (d)   The following schedule shows the merger consideration for the
            acquired properties and is reconciled to the purchase price of such
            properties.

            The cost of the property held by each target REIT (including
            capitalized merger costs of $960,000) has been allocated to real
            estate assets, acquired lease origination costs and acquired
            favorable 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 leases
            represents the value associated with a lease which has a rental
            stream with above market rates. The value assigned to buildings,
            land and leases approximates their fair value.

The following schedule shows the difference between historical costs (net of
accumulated depreciation and amortization) 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 allocation to
acquired lease origination costs will result in an increase in amortization
expense. For each $1,000,000 increase in acquired real estate leases, the
related pro forma amortization expense will increase by approximately $255,000
per year.

      (e)   Management fees of $68,000 charged by FSP Corp. to the target REITs
            for the three months ended March 31, 2006 have been eliminated from

            April 28, 2006 and approximately 10,972,000 shares of FSP common
            stock will be issued in exchange for the 2,153.25 outstanding shares
            of target REIT preferred stock in connection with the mergers.
            Stockholders' equity will be adjusted by the net difference between
            the assets and liabilities acquired in the merger. The following
            schedule shows a reconciliation detailing the adjustments to
            additional paid-in-capital.

      The following tables present on a per share basis:

      (a) Basic and diluted net income per share, book value per share, and
dividends per share declared for 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:

      Target REIT                            Exchange Ratio

      The pro forma financial data and equivalent pro forma data are unaudited
and are not necessarily indicative of the operating results that would have been
achieved had the mergers occurred as of the beginning of the period and should
not be construed as representative of future operations.

      FSP Corp. calculates historical book value per share by dividing
stockholders' equity by the number of shares of common stock (or preferred
stock, in the case of the target REITs) outstanding at the end of each period.

      FSP Corp. calculates consolidated pro forma net income per share data for
FSP Corp. as if the mergers occurred on January 1, 2006 and resulted in weighted
average shares of 70,766,000 for the three months ended March 31, 2006, based on
the assumption that the market value of the FSP common stock is $21.01, the
weighted average stock price of the FSP common stock based on the stocks trading
activity from April 24, 2006 to April 28, 2006 and approximately 10,972,000
shares of FSP common stock are issued in exchange for the 2,153.25 outstanding
shares of target REIT preferred stock in connection with the mergers.

      FSP Corp. calculates consolidated pro forma book value per share data for
FSP Corp. as if the mergers occurred on March 31,2006 and resulted in an ending
number of shares of 70,766,000, based on the assumption that the market value of
the FSP common stock is $21.01, the weighted average stock price of the FSP
common stock based on the stocks trading activity from April 24, 2006 to April
28, 2006 and approximately 10,972,000 shares of FSP common stock are issued in
exchange for the 2,153.25 outstanding shares of target REIT preferred stock in
connection with the mergers.

      FSP Corp. calculates consolidated pro forma dividends per share by adding
the total dividends paid by FSP Corp. plus dividends paid by the target REITs
and dividing this sum by 70,766,000 shares, based on the assumption that FSP
issued approximately 10,972,000 of common stock in exchange for the 2,153.25
outstanding shares of target REIT preferred stock in connection with the mergers
as shown in the following table:
