1.       CERTAIN DEFINED TERMS

     As used herein the following terms shall have the meanings set forth below:

         (a) "Accrual Period" means the period commencing on the eleventh (11th)
day of a calendar month and ending on the tenth (10th) day of the succeeding
calendar month; provided that if this Note is dated as of any date other than
the eleventh (11th) day of a month, the first Accrual Period shall (i) consist
of only the date hereof, if the date hereof is the tenth (10th) day of a month,
or (ii) commence on the date hereof and shall end on the next tenth (10th) day
of a calendar month to occur after the date hereof.

         (b) "Applicable Interest Rate" shall mean an interest rate equal to
4.95% per annum.

         (c) "Constant Monthly Payment" shall mean a payment equal to
$373,639.00.

any other documents or instruments which now or shall hereafter wholly or
partially secure or guarantee payment of this Note or which have otherwise been
executed by Borrower and/or any other person in connection with the Loan.

         (f) "Lockout Period Expiration Date" shall mean the earlier of (a) the
fourth (4th) anniversary of date hereof and (b) two years and one day from the
"startup day" of any "real estate mortgage investment conduit" (as such terms
are defined in Sections 860G and 860D, respectively, of the Internal Revenue
Code of 1986, as amended or any successor statute thereto) which may acquire the
Loan.

         (g) "Maturity Date" shall mean June 11, 2013.









         (h) "Monthly Payment Date" shall mean the eleventh (11th) day of each
calendar month prior to the Maturity Date commencing on (i) the eleventh (11th)
day of the next succeeding calendar month after the date hereof if this Note is
dated on or prior to the eleventh (11th) day of a month, or (ii) the eleventh
(11th) day of the second succeeding calendar month after the date hereof if this

00/100 Dollars ($70,000,000.00) given by Borrower to (or for the benefit of)
Lender covering the fee estate of Borrower in certain premises located in
Bristol, State of Massachusetts, and other property, as more particularly
described therein (collectively, the "Property").

2.       PAYMENT TERMS

         (a) If this Note is dated as of a date other than the eleventh (11th)
day of a calendar month, a payment shall be due from Borrower to Lender on the
date hereof on account of all interest scheduled to accrue on the principal sum
from and after the date hereof through and including the last day of the current
Accrual Period. The Constant Monthly Payment shall be due from Borrower to
Lender on each Monthly Payment Date, with each Constant Monthly Payment to be
applied as follows: (i) first, to the payment of interest which has accrued
during the preceding Accrual Period computed at the Applicable Interest Rate,
and (ii) the balance toward the reduction of the principal sum. The balance of
the principal sum and all interest thereon shall be due and payable on the
Maturity Date. Interest on the principal sum of this Note shall be calculated by
multiplying the actual number of days elapsed in the period for which interest
is being calculated by a daily rate based on a 360-day year.

         (b) Unless payments are made in the required amount in immediately
available funds at the place where this Note is payable, remittances in payment
of all or any part of the Debt (defined below) shall not, regardless of any
receipt or credit issued therefor, constitute payment until the required amount
is actually received by Lender in funds immediately available at the place where
this Note is payable (or any other place as Lender, in Lender's sole discretion,
may have established by delivery of written notice thereof to Borrower) and
shall be made and accepted subject to the condition that any check or draft may
be handled for collection in accordance with the practice of the collecting bank
or banks.

3.       DEFAULT AND ACCELERATION

         (a) The whole of the principal sum of this Note, (b) interest, default
interest, late charges and other sums, as provided in this Note, the Security
Instrument or the other Loan Documents, (c) all other monies agreed or provided
to be paid by Borrower in this Note, the Security Instrument or the other Loan
Documents, (d) all sums advanced pursuant to the Security Instrument to protect
and preserve the Property and the lien and the security interest created
thereby, and (e) all sums advanced and costs and expenses incurred by Lender in
connection with the Debt (defined below) or any part thereof, any renewal,
extension, or change of or substitution for the Debt or any part thereof, or the
acquisition or perfection of the security therefor, whether made or incurred at
the request of Borrower or Lender (all the sums referred to in (a) through (e)
above shall collectively be referred to as the "Debt") shall without notice
become immediately due and payable at the option of Lender if any payment
required in this Note prior to the Maturity Date is not paid on the date when
due or on the happening of any other default, after the expiration of any
applicable notice and grace periods, herein or under the terms of the Security
Instrument or any of the other Loan Documents (collectively, an "Event of
Default"). Notwithstanding anything to the contrary contained herein, with
respect to only Borrower's first failure in any consecutive twelve (12) month
period to make Constant Monthly Payments within the time required under this
Note, no Event of Default shall be deemed to have occurred unless Borrower fails
to make payment on or before the date that is five (5) days after Lender
delivers notice of Borrower's breach to Borrower.




                                       -2-



4.       DEFAULT INTEREST

Borrower does hereby agree that upon the occurrence of an Event of Default,
Lender shall be entitled to receive and Borrower shall pay interest on the
entire unpaid principal sum at a rate (the "Default Rate") equal to (i) the
greater of (a) the Applicable Interest Rate plus three percent (3%) and (b) the
Prime Rate (as hereinafter defined) plus four percent (4%) or (ii) the maximum
interest rate that Borrower may by law pay, whichever is lower. The Default Rate
shall be computed from the occurrence of the Event of Default until the earlier
of the date upon which the Event of Default is cured or the date upon which the
Debt is paid in full. Interest calculated at the Default Rate shall be added to
the Debt, and shall be deemed secured by the Security Instrument. This
provision, however, shall not be construed as an agreement or privilege to
extend the date of the payment of the Debt, nor as a waiver of any other right
or remedy accruing to Lender by reason of the occurrence of any Event of
Default.

The "Prime Rate" shall mean the annual rate of interest publicly announced by
Citibank, N.A. in New York, New York, as its base rate, as such rate shall
change from time to time. If Citibank, N.A. ceases to announce a base rate,
Prime Rate shall mean the rate of interest published in The Wall Street Journal
from time to time as the Prime Rate. If more than one Prime Rate is published in
The Wall Street Journal for a day, the average of the Prime Rates shall be used,
and such average shall be rounded up to the nearest one-quarter of one percent
(.25%). If The Wall Street Journal ceases to publish the "Prime Rate", the
Lender shall select an equivalent publication that publishes such "Prime Rate",
and if such prime rates are no longer generally published or are limited,
regulated or administered by a governmental or quasi-governmental body, then
Lender shall select a comparable interest rate index.

5.       PREPAYMENT; DEFEASANCE

         (a) Borrower shall not have the right or privilege to prepay all or any
portion of the unpaid principal balance of this Note until the Monthly Payment
Date which is three months prior to the Maturity Date. From and after such date,
provided no Event of Default exists, the principal balance of this Note may be
prepaid, in whole but not in part, upon: (i) not less than 15 days prior written
notice (the "Prepayment Notice") to Lender specifying the scheduled payment date
on which prepayment is to be made (the "Prepayment Date"); (ii) payment of all
accrued and unpaid interest on the outstanding principal balance of this Note to
and including the Prepayment Date together with a payment of all interest which
would have accrued on the principal balance of this Note to and including the
last day of the Accrual Period in which the Prepayment Date occurs, if such
prepayment occurs on a date which is not the eleventh (11th) day of a calendar
month (the "Shortfall Interest Payment"); and (iii) payment of all other sums
then due under this Note, the Security Instrument and the other Loan Documents.
Lender shall not be obligated to accept any prepayment of the principal balance
of this Note unless it is accompanied by all sums due in connection therewith.







                                       -3-


         (b) (i) At any time from and after the Lockout Period Expiration Date
and provided no Event of Default exists at the time, Borrower may obtain the
release of the Property from the lien of the Security Instrument upon the
satisfaction of the following conditions precedent:

             (1) Borrower shall have provided Lender with not less than thirty
(30) days and not more than sixty (60) days prior written notice specifying the
date (the "Release Date") on which the Defeasance Deposit (hereinafter defined)
is to be made;

             (2) Borrower shall have paid to Lender all interest accrued and
unpaid on the principal balance of this Note to and including the Release Date;

             (3) Borrower shall have paid to Lender all other sums due and
payable under this Note, the Security Instrument and the other Loan Documents
through and including the Release Date (including, but not limited to, any
Constant Monthly Payment which may be due and payable on the Release Date);

             (4) Borrower shall have paid to Lender the Defeasance Deposit
(hereinafter defined);

             (5) The transactions contemplated by this Section 5(b) shall not
cause the Loan to lose its status as a "qualified mortgage" within the meaning
of Sections 860D and 860G(a)(3) of the Internal Revenue Code of 1986, as
amended, or any successor statute thereto; and

             (6) Borrower shall have delivered to Lender the following:

                 (A) a security agreement, in form and substance satisfactory to
Lender, creating a first priority lien on the Defeasance Deposit and the
Government Securities (hereinafter defined) purchased on behalf of Borrower with
the Defeasance Deposit in accordance with the provisions of this Section 5(b)
(the "Pledge Agreement"), which Pledge Agreement shall provide, among other
things, that any excess payments of principal and interest received by Lender
under the Government Securities over the amount needed to make payments of
principal and interest and other sums due from Borrower hereunder shall be
refunded to Borrower;

                 (B) a release of the Property from the lien of the Security
Instrument (for execution by Lender) in a form appropriate for the jurisdiction
in which the Property is located;

                 (C) an officer's certificate of Borrower certifying that the
requirements set forth in this Section 5(b) have been satisfied;

                 (D) a certificate by Borrower's independent public accountant
certifying that the cash flow from the Government Securities will be sufficient
to timely meet all Scheduled Defeasance Payments;







                                       -4-


                 (E) an opinion of counsel for Borrower in form satisfactory to
Lender stating, among other things, that Lender will have a perfected first
priority security interest in the Defeasance Deposit and the Government
Securities to be purchased on behalf of Borrower;

                 (F) evidence in writing from the applicable Rating Agencies (as
defined in the Security Instrument) to the effect that such release will not
result in a qualification, downgrade or withdrawal of any rating in effect
immediately prior to such defeasance for any Securities (as defined in the
Security Instrument); and

                 (G) such other certificates, documents or instruments as Lender
may reasonably request.

The Defeasance Deposit shall be used to purchase Government Securities which
provide payments which are (A) payable on or prior to, but as close as possible
to, all successive Monthly Payment Dates after the Release Date and the Maturity
Date and (B) in amounts necessary to meet the scheduled payments of principal
and interest due under this Note on such dates (the "Scheduled Defeasance
Payments"). Borrower, pursuant to the Pledge Agreement or other appropriate
documents, shall authorize and direct that the payments received from the
Government Securities be made directly to Lender and applied to satisfy the
obligations of the Borrower under this Note.

         (ii) Upon compliance with the requirements of this Section 5(b), the
Property shall be released from the lien of the Security Instrument and the
pledged Defeasance Deposit and the Government Securities purchased therewith
shall be the sole source of collateral securing this Note. In connection with
such release, Lender, or its designee, shall establish or designate a successor
entity (the "Successor Borrower") and Borrower shall transfer and assign all
obligations, rights and duties under and to this Note together with the pledged
Defeasance Deposit and/or Government Securities to such Successor Borrower. Such
Successor Borrower shall assume the obligations of Borrower under this Note and
the Pledge Agreement and Borrower shall be relieved of its obligations
thereunder. Borrower shall pay all costs and expenses incurred by Lender,
including Lender's attorneys' fees and expenses and any Rating Agency fees
incurred in connection with this Section 5(b).

         (iii) For purposes hereof, the following terms shall have the following
meanings:

               (1) The term "Defeasance Deposit" shall mean an amount equal to
the sum of (1) the amount which will be sufficient to purchase Government
Securities necessary to meet the Scheduled Defeasance Payments; and (2) any
revenue, documentary stamp or intangible taxes or any other tax or charge due in
connection with the transfer of this Note or otherwise required to accomplish
the agreements of this Section 5(b), all fees, costs and expenses incurred or to
be incurred by Lender in the purchase of such Government Securities and the
assumption payments referred to above;

               (2) The term "Government Securities" shall mean (A) U.S. Treasury
Obligations and (B) Non-U.S. Treasury Obligations;






                                       -5-


               (3) The term "U.S. Treasury Obligations" shall mean direct,
non-callable, fixed rate obligations of the United States of America; and

               (4) The term "Non-U.S. Treasury Obligations" shall mean
non-callable, fixed rate obligations, other than U.S. Treasury Obligations, that
are "government securities" within the meaning of Section 2(a)(16) of the
Investment Company Act of 1940, as amended.

             (iv) Following the delivery of the Defeasance Deposit to Lender,
Borrower shall not have any right to prepay this Note.

         (c) (C)Simultaneously with each Default Repayment (defined herein)
occurring prior to the Monthly Payment Date which is three months prior to the
Maturity Date, Borrower shall pay to Lender an amount equal to the greater of:
(A) three (3%) percent of the principal amount of this Note being prepaid; and
(B) the present value of a series of payments each equal to the Payment
Differential (hereinafter defined) and payable on each Monthly Payment Date over
the remaining original term of this Note and on the Maturity Date discounted at
the Reinvestment Yield (hereinafter defined) for the number of months remaining
from the date of the Default Repayment (the "Repayment Date") to each such
Monthly Payment Date and the Maturity Date. The term "Reinvestment Yield" as
used herein shall be equal to the lesser of (a) the (i) yield on the U.S.
Treasury issue (primary issue) with the same maturity date as the Maturity Date;
or (ii) if no such U.S. Treasury issue is available, then the interpolated yield
on the two U.S. Treasury issues (primary issues) with maturity dates (one prior
to and one following) that are closest to the Maturity Date; or (b) the (i)
yield on the U.S. Treasury issue (primary issue) with a term equal to the
remaining average life of the Debt, or (ii) if no such U.S. Treasury issue is
available, then the interpolated yield on the two U.S. Treasury issues (primary
issues) with terms (one prior to and one following) that are closest to the
remaining average life of the Debt, with each such yield being based on the bid
price for such issue as published in The Wall Street Journal on the date that is
14 days prior to the Repayment Date (or, if such bid price is not published on
that date, the next preceding date on which such bid price is so published) and
converted to a monthly compounded nominal yield. The term "Payment Differential"
as used herein shall be equal to (x) the Applicable Interest Rate minus the
Reinvestment Yield, divided by (y) 12 and multiplied by (z) the principal sum
being repaid on such Repayment Date after application of the Constant Monthly
Payment (if any) due on the date of the Default Repayment, provided that the
Payment Differential shall in no event be less than zero. In no event, however,
shall Lender be required to reinvest any repayment proceeds in U.S. Treasury
obligations or otherwise.

For purposes of this Note, the term "Default Repayment" shall mean a repayment
of all or any portion of the principal amount of this Note made during the
continuance of any Event of Default or after an acceleration of the Maturity
Date under any circumstances, including, without limitation, a repayment
occurring in connection with reinstatement of the Security Instrument provided
by statute under foreclosure proceedings or exercise of a power of sale, any
statutory right of redemption exercised by Borrower or any other party having a
statutory right to redeem or prevent foreclosure, any sale in foreclosure or
under exercise of a power of sale or otherwise.







                                       -6-


6.       SECURITY

This Note is secured by the Security Instrument and the other Loan Documents.
The Security Instrument is intended to be duly recorded in the public records of
the county where the Property is located. All of the terms, covenants and
conditions contained in the Security Instrument and the other Loan Documents are
hereby made part of this Note to the same extent and with the same force as if
they were fully set forth herein.

7.       SAVINGS CLAUSE

This Note is subject to the express condition that at no time shall Borrower be
obligated or required to pay interest on the principal balance due hereunder at
a rate which could subject Lender to either civil or criminal liability as a
result of being in excess of the maximum interest rate which Borrower is
permitted by applicable law to contract or agree to pay. If by the terms of this
Note, Borrower is at any time required or obligated to pay interest on the
principal balance due hereunder at a rate in excess of such maximum rate, the
Applicable Interest Rate or the Default Rate, as the case may be, shall be
deemed to be immediately reduced to such maximum rate and all previous payments
in excess of the maximum rate shall be deemed to have been payments in reduction
of principal and not on account of the interest due hereunder. All sums paid or
agreed to be paid to Lender for the use, forbearance, or detention of the Debt,
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated, and spread throughout the full stated term of the Note until payment
in full so that the rate or amount of interest on account of the Debt does not
exceed the maximum lawful rate of interest from time to time in effect and
applicable to the Debt for so long as the Debt is outstanding.

8.       LATE CHARGE

If any sum payable under this Note is not paid on the date on which it is due,
regardless of whether such failure shall constitute an Event of Default,
Borrower shall pay to Lender upon demand an amount equal to the lesser of five
percent (5%) of the unpaid sum or the maximum amount permitted by applicable law
to defray the expenses incurred by Lender in handling and processing the
delinquent payment and to compensate Lender for the loss of the use of the
delinquent payment and the amount shall be secured by the Security Instrument
and the other Loan Documents.

9.       NO ORAL CHANGE

This Note may not be modified, amended, waived, extended, changed, discharged or
terminated orally or by any act or failure to act on the part of Borrower or
Lender, but only by an agreement in writing signed by the party against whom
enforcement of any modification, amendment, waiver, extension, change, discharge
or termination is sought.

10.      JOINT AND SEVERAL LIABILITY

If Borrower consists of more than one person or party, the obligations and
liabilities of each person or party shall be joint and several.








                                       -7-


11.      WAIVERS, ETC.

All payments required hereunder shall be made irrespective of and without any
deduction for, any setoff, defense or counterclaim. Borrower and all others who
may become liable for the payment of all or any part of the Debt do hereby
severally waive presentment and demand for payment, notice of dishonor, protest
and notice of protest and non-payment and all other notices of any kind, other
than notices specifically required by the terms of this Note, the Security
Instrument and the other Loan Documents. No release of any security for the Debt
or extension of time for payment of this Note or any installment hereof, and no
alteration, amendment or waiver of any provision of this Note, the Security
Instrument or the other Loan Documents made by agreement between Lender or any
other person or party shall release, modify, amend, waive, extend, change,
discharge, terminate or affect the liability of Borrower, and any other person
or entity who may become liable for the payment of all or any part of the Debt,
under this Note, the Security Instrument or the other Loan Documents. No notice
to or demand on Borrower shall be deemed to be a waiver of the obligation of
Borrower or of the right of Lender to take further action without further notice
or demand as provided for in this Note, the Security Instrument or the other
Loan Documents. In addition, acceptance by Lender of any payment in an amount
less than the amount then due shall be deemed an acceptance on account only, and
the failure to pay the entire amount then due shall be and continue to be an
Event of Default. If Borrower is a partnership, the agreements herein contained
shall remain in force and applicable, notwithstanding any changes in the
individuals comprising the partnership, and the term "Borrower," as used herein,
shall include any alternate or successor partnership, but any predecessor
partnership and their partners shall not thereby be released from any liability.
If Borrower is a corporation or limited liability company, the agreements
contained herein shall remain in full force and applicable notwithstanding any
changes in the shareholders or members comprising, or the officers and directors
or managers relating to, the corporation or limited liability company, and the
term "Borrower" as used herein, shall include any alternative or successor
corporation or limited liability company, but any predecessor corporation or
limited liability company shall not be relieved of liability hereunder. (Nothing
in the foregoing sentence shall be construed as a consent to, or a waiver of,
any prohibition or restriction on transfers of interests in a partnership,
corporation or limited liability company which may be set forth in the Security
Instrument or any other Loan Document.)

12.      TRANSFER

Upon the transfer of this Note, Borrower hereby waiving notice of any such
transfer, Lender may deliver all the collateral mortgaged, granted, pledged or
assigned pursuant to the Security Instrument and the other Loan Documents, or
any part thereof, to the transferee who shall thereupon become vested with all
the rights herein or under applicable law given to Lender with respect thereto,
and Lender shall thereafter forever be relieved and fully discharged from any
liability or responsibility in the matter; but Lender shall retain all rights
hereby given to it with respect to any liabilities and the collateral not so
transferred.

13.      WAIVER OF TRIAL BY JURY

BORROWER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE RIGHT TO
TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM, WHETHER IN CONTRACT,
TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE LOAN, THE APPLICATION
FOR THE LOAN, THIS NOTE, THE SECURITY INSTRUMENT OR THE OTHER LOAN DOCUMENTS OR
ANY ACTS OR OMISSIONS OF LENDER, ITS OFFICERS, EMPLOYEES, DIRECTORS OR AGENTS IN
CONNECTION THEREWITH.

14.      EXCULPATION

of Borrower to pay the Debt and for the performance of the other agreements,
covenants and obligations contained herein and in the Security Instrument and
the other Loan Documents shall be limited as set forth in Article 13 of the
Security Instrument.

15.      AUTHORITY

Borrower (and the undersigned representative of Borrower, if any) represents
that Borrower has full power, authority and legal right to execute and deliver

Note, the Security Instrument and the other Loan Documents constitute valid and
binding obligations of Borrower.

16.      APPLICABLE LAW

the laws of the state in which the Property is located and the applicable laws
of the United States of America.

17.      COUNSEL FEES

In the event that it should become necessary to employ counsel to collect the
Debt or to protect or foreclose the security therefor, Borrower also agrees to
pay all reasonable fees and expenses of Lender, including, without limitation,
reasonable attorney's fees for the services of such counsel whether or not suit
be brought.
