                          AGREEMENT AND PLAN OF MERGER

            This AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and
entered into as of August 13, 2004 by and among Franklin Street Properties Corp.
(the "Company"), a Maryland corporation, the wholly-owned acquisition
subsidiaries of the Company, each a Delaware corporation (each an "Acquisition
Subsidiary" and, collectively, the "Acquisition Subsidiaries"), listed on the
signature pages hereto and the other corporations, each a Delaware corporation
(each, a "Target REIT" and, collectively, the "Target REITs"), also listed on
the signature pages hereto.

                                    RECITALS

            WHEREAS, the Target REITs are the owners of certain real properties
listed on Exhibit A hereto (each such property, including any buildings,
structures or other improvements situated thereon, a "Property" and,
collectively, the "Properties");

            WHEREAS, the board of directors of the Company (the "Company
Board"), boards of directors of each of the Acquisition Subsidiaries (such
boards of directors, collectively, the "Acquisition Boards of Directors") and
the boards of the directors of each of the Target REITs (such boards of
directors, collectively, the "Target Boards of Directors") believe that it is in
the best interests of the Company, each of the Acquisition Subsidiaries and each
of the Target REITs, respectively, and their respective stockholders, to
consummate, and have approved, the business combination transaction provided for
herein, pursuant to which each Target REIT will be merged with and into an
Acquisition Subsidiary, with the respective Acquisition Subsidiary continuing as
the surviving entity (each such transaction, a "Merger" and, collectively, the
"Mergers");

            WHEREAS, the Company Board, the Acquisition Boards of Directors and
the Target Boards of Directors have agreed to effect the transactions provided
for herein upon the terms and subject to the conditions set forth herein;

            WHEREAS, the Company, the Acquisition Subsidiaries and the Target
REITs desire to make certain representations, warranties and agreements in
connection with the Mergers.

            NOW, THEREFORE, in consideration of the foregoing and of the
representations, warranties, covenants and agreements contained herein, the
parties hereto hereby agree as follows:

ARTICLE 1   THE MERGERS

      1.1 The Mergers. Subject to the terms and conditions of this Agreement, at
the Effective Time (as hereinafter defined), each Target REIT will be merged
with and into an Acquisition Subsidiary in accordance with the applicable


                                       1


provisions of the Delaware General Corporation Law ("DGCL"), and the separate
existence of each Target REIT shall thereupon cease. Each Acquisition Subsidiary
shall continue as the surviving entity of the Mergers (each a "Surviving
Corporation" and collectively, the "Surviving Corporations"). The parties hereby
agree that FSP Montague Business Center Corp. will merge with and into Montague
Acquisition Corp.; FSP Addison Circle Corp. will merge with and into Addison
Circle Acquisition Corp; FSP Royal Ridge Corp. will merge with and into Royal
Ridge Acquisition Corp.; and FSP Collins Crossing Corp. will merge with and into
Collins Crossing Acquisition Corp.

      1.2 The Closing. Subject to the terms and conditions of this Agreement,
the closing of the Mergers (the "Closing") shall take place at the offices of
Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston,
Massachusetts at 9:00 a.m., local time, on December 30, 2004 or at such other
time and date following the day on which the last of the conditions set forth in
Article 6 shall be fulfilled or waived in accordance herewith. The holders of
preferred stock in the Target REITs ("Target Stock") are hereinafter referred to
as the "Target REIT Stockholders." The holders of common stock of the Company,
$0.0001 par value per share ("Common Stock"), are hereinafter referred to as the
"Company Stockholders." The date on which the Closing occurs is hereinafter
referred to as the "Closing Date." After giving effect to the Mergers, the
Company and Acquisition Subsidiaries are hereinafter referred to as the
"Combined Company."

      1.3 Effective Time. If all of the conditions to a particular Merger set
forth in Article 6 shall have been fulfilled or waived in accordance herewith
with respect to the Company and the applicable Target REIT and this Agreement
shall not have been terminated as provided in Article 7 or Section 8.2(b), the
parties hereto shall promptly cause to be properly executed, verified and
delivered for filing on the Closing Date a certificate of merger satisfying the
requirements of the DGCL for such Merger (a "Certificate of Merger"). A Merger
shall become effective upon the acceptance for record of its Certificate of
Merger by the Secretary of State of the State of Delaware in accordance with the
DGCL or at such later time upon which the parties hereto shall have agreed and
designated in such filing in accordance with applicable law as the effective
time of the Mergers (the "Effective Time").

      1.4 Additional Action. The Surviving Corporations may, at any time from
and after the Effective Time, take any action, including executing and
delivering any document, in the name and on behalf of either the respective
Target REIT or the respective Acquisition Subsidiary, in order to consummate and
give effect to the transactions contemplated by this Agreement.

      1.5 Dissenting Shares.

            (a) For purposes of this Agreement, "dissenting shares" means Target
Stock held as of the Effective Time by a Target REIT Stockholder who has not
voted such Target Stock in favor of the adoption of this Agreement and the
Merger with respect to such Target REIT and with respect to which appraisal
shall have been duly demanded and perfected in accordance with Section 262 of


                                       2


the DGCL and not effectively withdrawn or forfeited prior to the Effective Time.
Dissenting shares shall not be converted into or represent the right to receive
the Merger Consideration (as defined below) unless the Target REIT Stockholder
holding such dissenting shares shall have forfeited his or her right to
appraisal under the DGCL or properly withdrawn his or her demand for appraisal.
If such Target REIT Stockholder has so forfeited or withdrawn his or her right
to appraisal of dissenting shares, then (i) as of the occurrence of such event,
such holder's dissenting shares shall cease to be dissenting shares and shall be
converted into and represent the right to receive the Merger Consideration
payable in respect of such Target Stock pursuant to Section 2.2 hereof, and (ii)
promptly following the occurrence of such event, the Company or the Surviving
Corporation shall deliver to such Target REIT Stockholder shares of Common Stock
and any cash in lieu of fractional shares of Target Stock, if applicable, to
which such holder is entitled pursuant to Section 2.2 hereof.

            (b) Each Target REIT shall give the Company (i) prompt notice of any
written demands for appraisal of any Target Stock, withdrawals of such demands,
and any other instruments that relate to such demands received by the respective
Target REIT and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal under the DGCL. No Target REIT shall,
except with the prior written consent of the Company, make any payment with
respect to any demands for appraisal of Target Stock or offer to settle or
settle any such demands.

      1.6 No Further Rights. From and after the Effective Time, no Target Stock
shall be deemed to be outstanding, and holders of certificates formerly
representing Target Stock shall cease to have any rights with respect thereto
except as provided herein or by law.

      1.7 Withholding Rights. Notwithstanding any provision of this Agreement,
each of the Company and any Acquisition Subsidiary shall be entitled to deduct
and withhold from the payments to be made pursuant to this Agreement, as
applicable, such amounts as it reasonably determines that it is required to
deduct and withhold with respect to the making of such payments under the Code
or any other applicable provision of law and to collect Forms W-8 or W-9, as
applicable, or similar information from the Target REIT Stockholders and any
other recipients of payments hereunder. To the extent the amounts are so
withheld by either the Company or any Acquisition Subsidiary, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the Target REIT shares in respect of which such deduction and
withholding was made by the Company or the Acquisition Subsidiary.


ARTICLE 2   MERGER CONSIDERATION

      2.1 Cancellation of Target Stock. As a result of the Mergers and without
any action on the part of the Target REIT Stockholders, all Target Stock in each
Target REIT with respect to which a Merger has become effective shall cease to
be outstanding, shall be canceled and retired and shall cease to exist and each
Target REIT Stockholder shall thereafter cease to have any rights with respect
to such Target Stock (other than with respect to any dissenting shares).


                                       3


      2.2 Merger Consideration.

            (a) At the Effective Time, by virtue of the Mergers and without any
further action by the Company, any Acquisition Subsidiary or any Target REIT,
each Target REIT Stockholder in each Target REIT with respect to which a Merger
has become effective shall receive for each share (or fraction thereof) of
Target Stock of such Target REIT that such Target REIT Stockholder holds of
record, that number of shares of Common Stock in the Combined Company set forth
on Exhibit B attached hereto opposite the name of the applicable Target REIT
(the "Merger Consideration"). At the Effective Time, by virtue of the Mergers
and without any further action by any party, each share of common stock, $.0001
par value per share, of each Target REIT held by the Company shall be cancelled
and shall cease to exist and no stock of the Company or other consideration
shall be delivered in exchange therefor, and the Company hereby waives any right
that it may have under the certificate of incorporation of each Target REIT or
otherwise to receive any consideration in the Mergers in respect of such shares
of Target REIT common stock.

            (b) No certificate or scrip representing fractional shares of Common
Stock shall be issued upon the surrender of Target Stock, and such fractional
share interests shall not entitle the owner thereof to vote or to any other
rights of a stockholder of the Company. Notwithstanding any other provision of
this Agreement, each holder of shares of Target Stock converted pursuant to the
Mergers who would otherwise have been entitled to receive a fraction of a share
of Common Stock (after taking into account all Target Stock certificates
registered in the name of or delivered by such holder) shall receive, in lieu
thereof, cash (without interest) in an amount equal to such fractional part of a
share of Common Stock multiplied by $17.70, such amount to be rounded up to the
nearest whole cent.

            (c) The Company shall issue certificates representing shares of
Common Stock upon the surrender of Target Stock as soon as practicable after the
Effective Time.

            (d) The directors and officers of each Acquisition Subsidiary
immediately prior to the Effective Time shall be the initial directors and
officers of the respective Surviving Corporations, each to hold office in
accordance with the Certificate of Incorporation and Bylaws of such Surviving
Corporation. The certificate of incorporation and by-laws of each Acquisition
Subsidiary immediately prior to the Effective Time shall be the initial
certificate of incorporation and by-laws of the respective Surviving
Corporation, except that the name of each Surviving Corporation shall be amended
to be the name of the respective Target REIT immediately prior to the Effective
Time.

            (e) The Merger Consideration, including any cash in lieu of
fractional shares, shall be adjusted to reflect any reclassification, stock
split, reverse split, stock dividend, reorganization, recapitalization or other
like change with respect to Common Stock or Target Stock occurring (or for which
a record date is established) after the date hereof and prior to the Effective
Time.

good standing under the laws of, all jurisdictions in which the transaction of

financial condition of the Company (a "Company Material Adverse Effect").

            (b) Each of the Company and the Acquisition Subsidiaries has
provided each Target REIT with a true and complete copy of its articles or

the consummation of the transactions contemplated hereby or (B) any notice,
consent or waiver the absence of which would not have a Company Material Adverse
Effect and would not adversely affect the consummation of the transactions

permit the execution, delivery and performance of (i) this Agreement, (ii) all

transactions contemplated hereby, and no consent or approval of any third party

applicable to such SEC Documents. None of the SEC Documents, at the time of
filing contained or will contain any untrue statements of a material fact or

agents, in such capacity, at law or in equity, or before or by any federal,

any reference to the "Company" shall be deemed to include the Subsidiaries.

accurately set forth the amount of any Taxes relating to the applicable period;

            (c) The Company has withheld and paid all Taxes required to have
been withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder or other party;

be treated as a "real estate investment trust" (a "REIT") within the meaning of
Sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code").
For the periods described in the preceding sentence, the Company has met all
requirements necessary to be treated as a REIT for purposes of the income Tax
provisions of those states in which the Company is subject to income Tax and
which provide for the taxation of a REIT in a manner similar to the treatment of
REITs under Sections 856-860 of the Code.

            (e) Neither the Internal Revenue Service (the "IRS") nor any other
governmental authority is now asserting by written notice to the Company or, to
the knowledge of the Company, threatening to assert against the Company any
deficiency or claim for additional Taxes. There is no dispute or claim
concerning any Tax liability of the Company either claimed or raised in writing
by the IRS. There is no dispute or claim of a material nature concerning any Tax
liability of the Company either claimed or raised in writing by any governmental
authority other than the IRS, or, to the knowledge of the Company, which may be
claimed or raised by any federal or state governmental authority. No written
claim has ever been made by a Taxing authority in a jurisdiction where the
Company does not file reports and returns asserting that the Company is or may
be subject to Taxation by that jurisdiction.

      3.10 Full Disclosure. The representations of the Company contained in this
Agreement do not contain any untrue statement of a material fact or omit to
state any material fact necessary to make the statements made herein not
misleading, and none of the information supplied or to be supplied by the
Company for inclusion in the Consent Solicitation/Prospectus to be distributed
to Target REIT Stockholders, pursuant to Section 5.3 hereof (the "Consent
Solicitation/Prospectus") contains any untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which

Company shall, together with the Target REITS, prepare, file and disseminate
such amendment or supplement. To the Company's knowledge, all of the

a Target REIT Material Adverse Effect and would not adversely affect the
consummation of the transactions contemplated hereby; (iv) result in the
imposition of any mortgage, pledge, security interest, encumbrance, charge or
other lien (whether arising by contract or by operation of law) upon any
property or assets of the Target REIT; or (v) violate any order, writ,

officers, employees or agents, in such capacity, at law or in equity, or before
or by any federal, state or local commission, board, bureau, agency or
instrumentality that would, individually or in the aggregate, reasonably be
expected to have a Target REIT Material Adverse Effect.

assets reflected in the most recent Target REIT Balance Sheet and will hold good
and marketable title to such assets, and any assets acquired by the Target REIT

in the first sentence of this Section 4.7 are owned free and clear of any and

      4.10 Compliance with Laws; Permits; Environmental Matters.

            (a) The Target REIT has complied with all applicable Environmental

the past five years and which the Target REIT has possession of or access to has

income Tax provisions of those states in which the Target REIT is subject to
income Tax and which provide for the taxation of a REIT in a manner similar to
the treatment of REITs under Sections 856-860 of the Code.


                                       16


            (e) Neither the IRS nor any other governmental authority is now
asserting by written notice to the Target REIT or, to the knowledge of the
Target REIT, threatening to assert against the Target REIT any deficiency or
claim for additional Taxes. There is no dispute or claim concerning any Tax
liability of the Target REIT either claimed or raised in writing by the IRS.
There is no dispute or claim of a material nature concerning any Tax liability
of the Target REIT either claimed or raised in writing by any governmental
authority other than the IRS, or, to the knowledge of the Target REIT, which may
be claimed or raised by any federal or state governmental authority. No written
claim has ever been made by a Taxing authority in a jurisdiction where the
Target REIT does not file reports and returns asserting that the Target REIT is
or may be subject to Taxation by that jurisdiction.

            (f) Each of the representations set forth in Exhibit C is true,
accurate and complete.

REIT is engaged, directly or indirectly, in any discussions or negotiations with
any other party with respect to an Acquisition Proposal (as defined in Section
5.5(b).

with respect to, assist or participate in any effort or attempt by any person
with respect to, or otherwise cooperate in any way with, any Acquisition
Proposal.

Notwithstanding the foregoing, prior to the adoption of this Agreement by the
respective Target REIT Stockholders (the "Specified Time"), the Target REITs
may, to the extent necessary to act in a manner consistent with the respective
fiduciary obligations of the Target Board of Directors, as determined in good
faith by such respective Target Board of Directors, after consultation with
outside counsel, in response to a Superior Proposal that did not result from a
breach by the respective Target REIT of this Section 5.5, and subject to
compliance with Section 5.5(c), (x) furnish information with respect to such
Target REIT to the person making such Superior Proposal and its Representatives
pursuant to a customary confidentiality agreement and (y) participate in
discussions or negotiations with such person and its Representatives regarding
any Superior Proposal. Without limiting the foregoing, it is agreed that any
violation of the restrictions set forth in this Section 5.5(a) by any
Representative of any Target REIT, whether or not such person is purporting to
act on behalf of a Target REIT or otherwise, shall be deemed to be a breach of
this Section 5.5(a) by the respective Target REIT.

            (b) No Target REIT Board of Directors nor any committee thereof
shall:

                  (i) except as set forth in this Section 5.5, withdraw or
modify, or publicly (or in a manner designed to become public) propose to
withdraw or modify, in a manner adverse to the Company or any other Target REIT,
its approval or recommendation with respect to the adoption of this Agreement
and approval of the Mergers contemplated hereby;

                  (ii) cause or permit its Target REIT to enter into any letter
of intent, memorandum of understanding, agreement in principle, acquisition
agreement, merger agreement or similar agreement constituting or relating to any
Acquisition Proposal (other than a confidentiality agreement referred to in
Section 5.5(a) entered into in the circumstances referred to in Section 5.5(a));
or


                                       19


                  (iii) adopt, approve or recommend, or publicly propose to
adopt, approve or recommend, any Acquisition Proposal.

Notwithstanding the foregoing, a Target REIT Board of Directors may, in response
to a Superior Proposal that did not result from a breach by such Target REIT of
this Section 5.5, withdraw or modify its recommendation with respect to the
adoption of this Agreement and approval of the Mergers contemplated hereby if
such Target REIT Board of Directors determines in good faith (after consultation
with outside counsel) that its fiduciary obligations require it to do so, but
only at a time that is prior to the Specified Time and is after the fifth
business day following receipt by the Company of written notice advising it that
such Target Board of Directors desires to withdraw or modify the recommendation
due to the existence of a Superior Proposal, specifying the material terms and
conditions of such Superior Proposal and identifying the person making such
Superior Proposal. Nothing in this Section 5.5 shall be deemed to (A) permit any
Target REIT to take any action described in clauses (ii) or (iii) of the first
sentence of this Section 5.5(b), (B) affect any obligation of the Company or the
Target REITs under this Agreement or (C) limit a Target REITs' respective
obligation to solicit consents from its Target REIT Stockholders, regardless of
whether such Target REIT Board of Directors has withdrawn or modified its
recommendation.

            (c) Each Target REIT shall immediately advise the Company and the
other Target REITs orally, with written confirmation to follow promptly (and in
any event within 24 hours), of any Acquisition Proposal or any request for
nonpublic information in connection with any Acquisition Proposal, or of any
inquiry with respect to, or that could reasonably be expected to lead to, any
Acquisition Proposal, the material terms and conditions of any such Acquisition
Proposal or inquiry and the identity of the person making any such Acquisition
Proposal or inquiry. No Target REIT shall provide any information to or
participate in discussions or negotiations with the person or entity making any
Superior Proposal until five business days after such Target REIT has first
notified the Company and the other Target REITs of such Acquisition Proposal as
required by the preceding sentence. The Target REIT receiving an Acquisition
Proposal shall (i) keep the Company and the other Target REITs fully informed,
on a reasonably current basis, of the status and details (including any change
to the terms) of any such Acquisition Proposal or inquiry, (ii) provide to the
Company and the other Target REITs as soon as practicable after receipt or
delivery thereof copies of all correspondence and other written material sent or
provided to the Target REIT receiving an Acquisition Proposal from any third
party in connection with any Acquisition Proposal or sent or provided by such
Target REIT to any third party in connection with any Superior Proposal, and
(iii) if the Company shall make a counterproposal, consider and cause its
financial and legal advisors to negotiate on its behalf in good faith with
respect to the terms of such counterproposal. Contemporaneously with providing
any information to a third party in connection with any such Superior Proposal
or inquiry, the Target REIT receiving a Superior Proposal shall furnish a copy
of such information to the Company and the other Target REITs.


                                       20


            (d) Each Target REIT shall, and shall cause its Representatives to,
cease immediately all discussions and negotiations regarding any proposal that
constitutes, or could reasonably be expected to lead to, an Acquisition
Proposal. Each Target REIT shall use commercially reasonable efforts to have all
copies of all nonpublic information it and its Representatives have distributed
on or prior to the date of this Agreement to other potential purchasers returned
to such Target REIT as soon as possible.

            (e) For purposes of this Agreement:

                  "Acquisition Proposal" means, with respect to any Target REIT,
(i) any inquiry, proposal or offer for a merger, consolidation, dissolution,
sale of substantial assets, tender offer, recapitalization, share exchange or
other business combination involving such Target REIT, (ii) any proposal for the
issuance by such Target REIT of over 10% of its equity securities or (iii) any
proposal or offer to acquire in any manner, directly or indirectly, over 10% of
the equity securities or consolidated total assets of such Target REIT, in each
case other than the Mergers contemplated by this Agreement.

                  "Superior Proposal" means, with respect to any Target REIT,
any unsolicited, bona fide written proposal made by a third party to acquire
substantially all of the equity securities or assets of such Target REIT,
pursuant to a tender or exchange offer, a merger, a consolidation or a sale of
its assets, (i) on terms which such Target REIT's Board of Directors determines
in its good faith judgment to be more favorable from a financial point of view
to the stockholders of such Target REIT than the transactions contemplated by
this Agreement (after taking into account the written opinion with respect
thereto of a nationally recognized independent financial advisor), taking into
account all the terms and conditions of such proposal and this Agreement
(including any proposal by either the Company or such the Target REIT to amend
the terms of this Agreement) and (ii) that in the good faith judgment of the
Target REIT Board of Directors is reasonably capable of being completed on the
terms proposed, taking into account all financial, regulatory, legal and other
aspects of such proposal; provided, however, that no Acquisition Proposal shall
be deemed to be a Superior Proposal if any financing required to consummate the
Acquisition Proposal is not committed.

ARTICLE 6   CONDITIONS TO EACH PARTY'S OBLIGATIONS TO EFFECT THE MERGERS.

            The respective obligations of the parties hereto to consummate the
Mergers pursuant to the terms of this Agreement are subject to satisfaction of
the following conditions precedent on or prior to the Closing Date. In the event
that one or more of these conditions are not satisfied on or prior to the
Closing Date, the party or parties whose obligations hereunder are subject to
the satisfaction of such condition or conditions may either elect to terminate
this Agreement or waive the satisfaction of such condition. The conditions are:


                                       21


            (a) this Agreement and the Mergers shall have been approved by the
holders of a majority of the shares of Target Stock of each Target REIT other
than a Target REIT with respect to which this Agreement has been terminated in
accordance with Section 8.2(b);

            (b) all necessary consents, waivers, approvals, authorizations or
orders required to be obtained and the making of all filings required to be made
by any of the parties for the authorization, execution and delivery of this
Agreement and the consummation of the transactions contemplated thereby shall
have been obtained or made, as the case may be, on or prior to (and remaining in
effect at) the Closing Date;

            (c) FSP Corp. and each of the Target REITs shall have received, on
or prior to the Closing Date, an opinion from Wilmer Cutler Pickering Hale and
Dorr LLP to the effect that each Merger will be treated for federal income tax
purposes as a reorganization within the meaning of Section 368(a) of the Code
and confirming that, to the extent the matters discussed under the heading
"Material United States Federal Income Tax Considerations" in the Consent
Solicitation/Prospectus constitute matters of law, they are accurate in all
material respects (it being agreed that if Wilmer Cutler Pickering Hale and Dorr
LLP does not render such opinion, this condition shall nonetheless be satisfied
if another nationally recognized law firm renders such opinion, and that the
Company and the Target REITs shall use their respective reasonable best efforts
to obtain the opinion required by this subsection). Each of the Company and each
Target REIT agrees to provide customary representations to Wilmer Cutler
Pickering Hale and Dorr LLP (or such other law firm) in connection with the
issuance of such opinion;

            (d) either the President and Chief Executive Officer or the Vice
President and Chief Operating Officer of the Company shall have delivered to
each of the Target REITs a certificate on behalf of the Company, dated as of the
Closing Date, to the effect that there have been no material adverse changes in
the financial condition of the Company between the date of the most recent
Company Financial Statements and the Closing Date, and the President of each of
the Target REITs shall have delivered to the Company a certificate on behalf of
each Target REIT, each dated as of the Closing Date, to the effect that there
have been no material adverse changes in the financial condition of such Target
REIT between the date of the most recent Target REIT Financial Statements for
such Target REIT and the Closing Date;

            (e) there shall have been no statute, rule, order or regulation
enacted or issued by the United States or any State thereof, or by a court, that
prohibits the consummation of the Mergers; and

            (f) the representations set forth in Section 3 and Section 4 hereof
are true and complete in all material respects; provided, however, that the
party whose representation was not true and correct shall have no right to not
consummate the Closing as a result thereof.

      The conditions described in clause (b) above, may be waived by either the
Company or the Target REITs, as the case may be, in whole or in part if, in the
opinion of either the Company or the Target REITs, as the case may be, such
waiver does not materially affect the terms of the transaction, which waiver
shall not be unreasonably withheld.


                                       22


ARTICLE 7   TERMINATION AND WAIVER

      7.1 Termination. This Agreement may be terminated, and the Mergers may be
abandoned, at any time before the Closing Date, notwithstanding approval of the
Mergers by the Target REIT Stockholders: (a) by the mutual written consent of
the parties;

            (b) by the Company or any Target REIT if the Mergers have not been
consummated by March 30, 2005 (which date may be extended by mutual agreement of
the parties);

            (c) by the Company or any Target REIT if the conditions to the
Mergers set forth in Article 6 of this Agreement are not satisfied or waived on
the Closing Date; provided, however, that in the event of the failure of the
conditions set forth in clause (g) of Article 6, the party whose representation
was not true and correct shall have no right to terminate this Agreement as a
result thereof;

            (d) by the Company or any Target REIT, in the instance where the
Target REIT has received a Superior Proposal and the respective Target REIT
Board of Directors has withdrawn or modified its approval or recommendation with
respect to the adoption of this Agreement and approval of the Mergers
contemplated hereby, if at a meeting of Target REIT Stockholders (including any
adjournment or postponement thereof) or pursuant to a written consent in lieu of
a meeting, as contemplated by Section 5.3 above, the requisite vote of such
stockholders to adopt this Agreement and approve the Mergers contemplated hereby
shall not have been obtained within 75 days of mailing of the Consent
Solicitation/Prospectus.

      If a casualty occurs with respect to the Property owned by a particular
Target REIT, the Company Board has the right to terminate the Agreement with
respect to such Target REIT and to consummate the Mergers with the remaining
Target REITs as provided in Section 8.2(b) hereof. In addition, the Company
Board has the right to terminate this Agreement with respect to a Target REIT if
(i) after the receipt by any Target REIT of an Acquisition Proposal, if the
Company requests that such Target REIT Board of Directors reconfirm its
recommendation of this Agreement or the Merger with the respective Target REIT
and such Target REIT Board of Directors fails to do so within five business days
after its receipt of the Company's request or (ii) such Target REIT Board of
Directors (or any committee thereof) shall have approved or recommended to its
Target REIT Stockholders an Acquisition Proposal.

      7.2 Effect of Termination. In the event of termination of this Agreement
as provided in Section 7.1 hereof, this Agreement shall become void and there
shall be no liability or obligation on the part of any party hereto or its
respective affiliates, partners, directors or officers, except (i) with respect
to payment


                                       23


of expenses as described in Section 8.3 and (ii) to the extent that such
termination results from the willful breach of a party hereto of any of its
representations, warranties, covenants or agreements made in or pursuant to this
Agreement.

      7.3 Extension; Waiver. At any time prior to the Closing Date, the parties
hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties of the other
parties hereto contained herein or made in connection herewith, and (iii) waive
compliance with any of the agreements of the other parties hereto contained
herein. Any agreement on the part of a party hereto to any such extension or
waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party.

      7.4 No Survival of Representations and Warranties. None of the
representations and warranties contained in this Agreement shall survive the
Closing Date.

ARTICLE 8   MISCELLANEOUS

      8.1 Assignment. The Company may not assign its rights or obligations under
this Agreement without the consent of the applicable Target REIT. None of the
Target REITs may assign their rights or obligations under this Agreement.

      8.2 Risk of Loss.

            (a) Risk of loss or damage to the assets owned by each Target REIT
(the "Assets") by condemnation, eminent domain or similar proceedings (or deed
in lieu thereof), or by fire or any other casualty, from the date hereof through
the Closing Date, will be on the Target REIT owning such Assets, and thereafter
will be on the Combined Company.

            (b) In the event of loss or damage to the Assets that occurs prior
to the Closing Date, the applicable Target REIT shall use its commercially
reasonable efforts to effect a timely cure of such loss or damage prior to the
Closing Date. If the Target REIT is unable to effect such a timely cure, the
Target REIT shall so notify the Company, and thereafter, if such loss or damage
results in a Target REIT Material Adverse Effect, the Company and such Target
REIT shall use good faith efforts to amend this Agreement (without the need to
obtain the consent of any other Target REIT) to (A) reflect a decrease in the
amount of Merger Consideration to be issued with respect to the Target Stock of
such Target REIT based on such loss or damage and (B) extend the term of this
Agreement as reasonably necessary taking into account all financial, regulatory,
legal and other aspects of such amendment to this Agreement, including, but not
limited to, the need to resolicit the stockholders of such Target REIT with
respect to participation in the Mergers with the Merger Consideration adjusted
to reflect such loss or damage and consummate the Merger with such Target REIT
as soon as practicable thereafter; provided, however, that in the event the
Company and such Target REIT, after a good faith effort, cannot agree on a
decrease in the amount of Merger Consideration to be issued with respect to the


                                       24


Target Stock of such Target REIT based on such loss or damage within a
reasonable period of time following notice of such loss or damage, the Company
shall have the unilateral right to amend this Agreement to terminate this
agreement with respect to such Target REIT and consummate the Mergers with the
other Target REITS.

      8.3 Fees and Expenses. The costs associated with each independent
third-party appraisal of the fair market value of each Target REIT's real estate
("Appraisal") obtained by the respective Target Boards of Directors shall be
paid by the Target REIT owning the real estate that is the subject of the
Appraisal. The costs associated with investment banking advice and each fairness
opinion of each Target REIT (the "Fairness Opinions") obtained by the respective
Target Boards of Directors shall be paid by the Target REIT receiving such
advice and Fairness Opinion. The fees and expenses of each Target REIT's legal
counsel shall be paid by the respective Target REIT. All other expenses related
to the Mergers and the transactions contemplated hereby, including, without
limitation, consulting, legal, accounting and administrative expenses, shall be
paid by the Company.

      8.4 Entire Agreement; Modifications; Amendments.

            (a) This Agreement embodies and constitutes the entire understanding
between the parties with respect to the transactions contemplated herein, and
all prior or contemporaneous agreements, understandings, representations and
statements, oral or written, are merged into this Agreement. Except as expressly
otherwise provided herein, neither this Agreement nor any provision hereof may
be waived, modified, amended, discharged or terminated except by an instrument
in writing signed by the party against which the enforcement of such waiver,
modification, amendment, discharge or termination is sought, and then only to
the extent set forth in such instrument.

            (b) Subject to applicable law, this Agreement may be amended by the
Company and the Target REITs at any time prior to the filing of the Certificates
of Merger with the Secretary of State of the State of Delaware; provided,
however, that after approval by Target REIT Stockholders as provided in Section
6 above, without further approval of the Target REIT Stockholders of such Target
REIT, no amendment may be made that alters or changes (i) the amount or kind of
Merger Consideration which the Target REIT Stockholders in such Target REIT
shall be entitled to receive, (ii) the certificate of incorporation or bylaws of
such Target REIT or (iii) the terms and conditions of this Agreement, if such
alteration or change would have a material adverse effect on such Target REIT
Stockholders.

      8.5 Notices. All notices, demands or other writings in this Agreement
provided to be given or made or sent, or which may be given or made or sent, by

                                       26


      8.7 Captions. The captions used in this Agreement are for convenience only
and shall not be deemed to construe or to limit the meaning of the language of
this Agreement.

      8.8 Counterparts. This Agreement may be executed in any number of
identical counterparts. If so executed, each of such counterparts is to be
deemed an original for all purposes, and all such counterparts shall
collectively constitute one agreement, but in making proof of this Agreement it
shall not be necessary to produce or account for more than one such counterpart.

      8.9 Binding Effect. Subject to the restrictions on assignment contained in
Section 8.1 hereof, this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective heirs, legal representatives,
successors and assigns.

      8.10 Attorneys' Fees. Subject to the requirements of Section 8.12 hereof,
should any party hereto employ an attorney or attorneys to enforce any of the
provisions hereof or to protect its interest in any manner arising under this
Agreement, or to recover damages for the breach hereof, the nonprevailing party
or parties in any action pursued in courts of competent jurisdiction (the
finality of which action is not legally contested) agrees to pay to the
prevailing party or parties all reasonable costs, damages and expenses,
including attorneys' fees, expended or incurred in connection therewith;
provided, however, that if more than one item is disputed and the final decision
is against each party as to one or more of the disputed items, then such costs,
expenses and attorneys' fees shall be apportioned in accordance with the
monetary values of the items decided against each party.

      8.11 No Waiver; Severability. The failure of any party hereto to enforce
at any time any of the provisions of this Agreement shall in no way be construed
to be a waiver of any such provision, and shall in no way affect the validity of
this Agreement or any part hereof or the right of any party thereafter to
enforce each and every such provision. No waiver of any breach of this Agreement
shall be held to be a waiver of any other or subsequent breach. If any provision
of this Agreement, or the application thereof to any person or circumstances
shall, for any reason and to any extent, be invalid or unenforceable, but the
extent of the invalidity or unenforceability does not destroy the basis of the
bargain between the parties as contained herein, the remainder of this Agreement
and the application of such provision to other persons or circumstances shall
not be affected thereby but rather shall be enforced to the greatest extent
permitted by law.

      8.12 No Joint and Several Liability. If one of the Target REITs defaults
under, or is in breach of, any of its representations, warranties or covenants
contained in this Agreement, such Target REIT shall be accountable to the
Company and shall be liable for the damages caused by such default or breach to
the extent provided in Section 7.2 hereof. Each Target REIT hereunder has
undertaken obligations and made representations, warranties, disclosures and
covenants herein and in and pursuant to the exhibits hereto solely with respect
to itself and the Property owned by it. Nothing contained herein, however, is
intended to make any of the Target REITs jointly and severally liable for the
default or breach by any of the other Target REITs, and with respect to any such


                                       27


default and breach such shall be solely the obligation and responsibility of the
Target REIT responsible for the default or breach, and no Target REIT shall be
liable to any other Target REIT hereunder.

      8.13 Applicable Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware.

                                    Exhibit C

Each Target REIT hereby makes the representations set forth below, which such
Target REIT understands will be relied upon by Wilmer Cutler Pickering Hale and
Dorr LLP in rendering a legal opinion with respect to the discussion set forth
under "Material United States Federal Income Tax Considerations" in the Consent
Solicitation/Prospectus. Notwithstanding anything to the contrary that may be
expressed or implied herein, each Target REIT makes no representations regarding
any matter for any periods commencing on or after the Effective Time (as defined
in the Agreement). Each Target REIT has made or has caused to be made such
investigations as are necessary to certify the accuracy of the information set
forth herein. To the extent the representations and statements in this letter
involve matters of law, each Target REIT acknowledges that Gehrke, Gish & Umana
LLP and Wilmer Cutler Pickering Hale and Dorr LLP has reviewed such matters with
it.

1.    The Target REIT has operated in accordance with (a) the Certificate of
      Incorporation of the Target REIT, as amended through the date hereof (the
      "Certificate of Incorporation"), (b) the By-Laws of the Target REIT as
      amended through the date hereof, (c) the applicable state law under which
      the Target REIT is organized, and (d) the representations in this Exhibit.

2.    The Target REIT is not a bank (within the meaning of Section 581 of the
      Internal Revenue Code of 1986, as amended (the "Code")), financial
      institution (described in Section 591 of the Code), small business
      investment company operating under the Small Business Act of 1958,
      business development corporation (within the meaning of Section
      582(c)(2)(B) of the Code) or insurance company (subject to Subchapter L of
      Subtitle A, Chapter 1 of the Code).

3.    The Target REIT's taxable year for federal income tax purposes is the
      calendar year. The Target REIT made the election specified in Section
      856(c) of the Code to be a real estate investment trust ("REIT") under the
      Code, effective for its first taxable year. The Target REIT's election to
      be taxed as a REIT has not been revoked or terminated.

4.    For each taxable year after its first taxable year, (A) the beneficial
      ownership of the Target REIT has been held by 100 or more persons for at
      least 335 days for a taxable year of 12 months (or during a proportionate
      part of a taxable year of less than 12 months), and (B) at no time during
      the last half of such taxable year has more than 50% in value of the
      Target REIT's outstanding stock been owned, directly or indirectly (taking
      into account the constructive ownership rules applicable under Section 542
      of the Code as modified by Section 856(h) of the Code) by or for five or
      fewer individuals. Compliance with the 100 person test set forth in (A)
      above shall be determined in accordance with the Investment Company Act of
      1940 by disregarding the ownership of shares by any person who (i)


                                       33


      acquired such shares as a gift or bequest pursuant to a legal separation
      or divorce; (ii) is the estate of any person making such transfer to the
      estate; or (iii) is a company established exclusively for the benefit of
      (or wholly owned by) either the person making such transfer or a person
      described in (i) or (ii).

5.    The Target REIT at all times has been managed by one or more trustees or
      directors, and the beneficial ownership in the Target REIT has been
      evidenced by transferable shares.

6.    With the exception of the restrictions imposed on the transfers of the
      Target REIT capital stock under the Certificate of Incorporation, there
      are no restrictions on the transfer of the Target REIT's capital stock,
      other than restrictions imposed by applicable securities law.

7.    At least 75% of the gross income of the Target REIT for each of its
      taxable years consisted of amounts from the following sources:

            (A) Rents from real property.

                  (i) Rents from real property shall include the following:

                        (a) Rents from interests in real property;

                        (b) Rent attributable to personal property leased under,
      or in connection with, a lease of real property, but only if the rent
      attributable to such personal property for the taxable year does not
      exceed 15% of the total rent received for the real and personal property
      under the lease (determined by the ratio of the average of the "adjusted
      bases" of the personal property subject to the lease at the beginning and
      end of the year to the average of the total "adjusted bases" of all
      property subject to the lease at the beginning and end of the year); and

                        (c) Charges for services customarily furnished or
      rendered in connection with the rental of real property, whether or not
      separately stated.

                  (ii) Rents from real property shall exclude the following:

                        (a) Amounts received or accrued for, or in connection
      with, the use of real property (or deemed to be for use of real property
      under Code Section 856(d)), the determination of which depends in whole or
      in part on the income or profits derived by any person from such property
      (except such amounts as may be based on a fixed percentage or percentages
      of receipts or sales if such rental provisions conform with normal
      business practice and are not used as a means to allow the Target REIT to
      receive rents that depend in whole or in part on the income or profits
      derived by any person from the property);


                                       34


                        (b) Amounts received or accrued from any person in which
      the Target REIT owns (A) in the case of a corporation, 10% or more of the
      combined voting power of all classes of stock entitled to vote (and for
      taxable years beginning after December 31, 2000, 10% or more of the total
      value of shares of all classes of stock), or (B) in the case of an entity
      other than a corporation, an interest of 10% or more in the assets or net
      profits of such entity. For purposes of this paragraph, ownership will be
      determined by taking into account the attribution rules of Code Section
      318 (as modified by Code Section 856(d)(5));

                        (c) Any "impermissible tenant service income." For this
      purpose, "impermissible tenant service income" generally shall include all
      income received from a tenant if the Target REIT (directly or indirectly)
      provides services to the tenant that (i) are not customarily rendered in
      connection with the rental of space for occupancy only and (ii) are
      rendered primarily for the convenience of the tenant; provided, however,
      that if the greater of (X) the income derived from all such services to
      the tenant or (Y) 150% of the cost of providing such services to the
      tenant is less than 1% of the income received by the Target REIT with
      respect to the property in which the tenant leased space, only such
      greater amount shall be treated as impermissible tenant service income;
      and provided further, however, that no income from the tenant shall be
      treated as impermissible tenant service income if the impermissible
      services are performed by an "independent contractor" within the meaning
      of Section 856(d)(3) of the Code from whom the Target REIT derives no
      income.

            (B) Interest received or accrued that is attributable to obligations
      held by the Target REIT that are secured by mortgages on real property or
      on interests in real property;

            (C) Gain realized upon the sale of real property (other than assets
      or portions thereof considered to be stock in trade, included in inventory
      or held for sale to customers in the ordinary course of a trade or
      business ("Dealer Property"));

            (D) Dividends and gain from the sale or other disposition of
      transferable interests in other real estate investment trusts other than
      interests that were Dealer Property;

            (E) Abatements and refunds of real property taxes;

            (F) Income and gain derived from "foreclosure property" (as defined
      in Section 856(e) of the Code);

            (G) Amounts (other than amounts the determination of which depends
      in whole or in part on the income or profits of any other person) received
      or accrued as consideration for entering into agreements (X) to make loans
      secured by mortgages on real property or on interests in real property or
      (Y) to purchase or lease real property;


                                       35


            (H) Gain from the sale or other disposition of real estate assets
      that are Dealer Properties but which dispositions are excluded from
      "prohibited transactions" as a result of Section 857(b)(6) (exempting
      certain sales of real estate assets if held for at least four years); and

            (I) "Qualified temporary investment income" as defined in Section
      856(c)(5)(D) of the Code.

8.    At least 95% of the gross income of the Target REIT for each of its
      taxable years consisted of amounts from the following sources:

            (A) Income specified in Sections 7(A) through (I) hereof;

            (B) Dividends;

            (C) Interest; and

            (D) Gain from the sale or other disposition of stock and securities
      other than Dealer Property.

9.    The Target REIT was incorporated in a taxable year beginning after August
      5, 1997.

10.   During each of the Target REIT's taxable years, at least 75% of the total
      value of the assets of the Target REIT has consisted of the following
      types of assets:

            (A) Land;

            (B) Buildings, including wiring, plumbing systems, elevators,
      escalators, and other structural components thereof, but not including any
      personal property associated with such real property (such as furnishings,
      appliances, draperies, equipment, machinery, etc.);

            (C) Loans (including accrued interest thereon) directly secured by a
      mortgage on real property of the type described in paragraphs (A) or (B)
      above;

            (D) Cash and cash items, including cash on hand, time and demand
      deposits with financial institutions, and receivables arising in the
      ordinary course of the Target REIT's operations (other than those
      purchased from another person) but excluding bankers' acceptances,
      repurchase agreements, and other similar instruments;


                                       36


            (E) Securities (including accrued interest thereon) issued or
      guaranteed by the United States or by a person controlled or supervised by
      and acting as an instrumentality of the United States, pursuant to any
      authority granted by Congress, or any certificates of deposit for any of
      the foregoing; and

             (F) Equity interests in corporations which have made qualifying
      elections to be taxed as real estate investment trusts under Sections 856
      through 860 of the Code and continue to satisfy the requirements for such
      treatment.

11.   The Target REIT has not owned and will not own securities in any issuer
      (other than a REIT or a "qualified REIT subsidiary" within the meaning of
      Section 856(i) of the Code) that either (A) represent in excess of 10% of
      the (i) voting power of the outstanding securities, or (ii) value of the
      outstanding securities, of such issuer or (B) have an aggregate value in
      excess of 5% of the value of the total assets of the Target REIT.

12.   For each of its taxable years, the Target REIT distributed to its
      shareholders at such times and in such manner as required by Code Sections
      858, 561 and 563 at least 90% of its ordinary REIT taxable income (as
      defined in Section 857(b) of the Code, excluding any net capital gain) for
      such taxable year.
13.   The Target REIT does not have and has not had at the close of any taxable
      year any undistributed "C corporation" earnings and profits.

14.   The Target REIT has not made any distributions to its shareholders with
      respect to its capital stock unless such distribution was pro-rata, with
      no preference to any stock of a particular class as compared with other
      stock of the same class, and it has not made any distributions that gave a
      preference to one class of stock as compared with another class except to
      the extent that the former is entitled (without reference to waivers of
      their rights by shareholders) to such preference.

15.   Except as set forth on Schedule 1 attached hereto, the Target REIT has
      never owned any interest in any subsidiary, corporation, partnership,
      limited liability company or other entity.

      Company will not directly or indirectly own 10% or more of any tenant from
      which the Target REIT collects rent.

17.   To the best of the Target REIT's knowledge, as a result of the Merger the

      of the outstanding securities of any issuer.


                                       37


18.   To the best of the Target REIT's knowledge, any person who performs
      services for tenants on behalf of the Target REIT and who is an
      "independent contractor" within the meaning of Section 856(d)(3) of the
      Code with respect to the Target REIT will be an "independent contractor"
      with respect to the Company following the Merger.
