satisfies the conditions set forth in this definition or with respect to 
which the Requisite Banks have granted the necessary waivers pursuant to

periods of time as Borrower has included the same on the list of 
Unencumbered Properties attached to the most recent Compliance 
Certificate delivered hereunder.

Property at any time, an amount computed as follows: (a) the Net 
Operating Income of such Unencumbered Property for the most recent 
fiscal quarter of the Borrower for which financial statements have been 
delivered to the Agent pursuant to 7.4; (b) then multiplying by four 
(4);  (c) then subtracting from such annualized Net Operating Income the

exceeds fifteen percent (15%) of the Value of All Unencumbered 
Properties as of the end of the most recent fiscal quarter of the 
Borrower for which financial statements have been delivered to the Agent 
pursuant to 7.4 then the amount in excess of said 15% level will be 
excluded when computing the Unencumbered Property Value for such 
Unencumbered Property.  With respect to any Unencumbered Property which, 
during the applicable fiscal quarter, has been acquired by Borrower or 
has had the building or buildings being constructed thereon completed 
and occupied by tenants, Borrower may compute the Unencumbered Property 
Value for such Unencumbered Property based on a pro forma Net Operating 
Income for such fiscal quarter, which computation must be approved by 
the Agent.

the Related Companies which is not secured by a Lien on any Properties 
including, without limitation, the Loans, the loans under the Revolving 
Credit Facility, the Subordinated Indebtedness and any Indebtedness 
evidenced by any bonds, debentures, notes or other debt securities 
presently outstanding or which may be hereafter issued by Borrower or by 
the Company.  Unsecured Indebtedness shall not include accrued ordinary 
operating expenses payable on a current basis.

     Value of All Unencumbered Properties. When determined as of the end 
of a fiscal quarter, an amount computed as follows: (a) Unencumbered Net 
Operating Income;  (b) then multiplying by four (4);  (c) then 
subtracting from such annualized Net Operating Income the Reserve Amount 
for all Unencumbered Properties;  and (d) dividing such difference by 
0.095.  When determined as of a date which is during a fiscal quarter 
based on an updated list of Unencumbered Properties attached to the 
applicable Compliance Certificate, the Value of All Unencumbered 
Properties most recently computed as provided in the preceding sentence 
of this definition will be adjusted by subtracting the Unencumbered 
Property Value of the previous Unencumbered Properties which have been 
deleted from such list and by adding the Unencumbered Property Value of 
the Unencumbered Properties which have been added to such list; 
provided, however, that to the extent the addition of Unencumbered 
Properties located in the United Kingdom causes the aggregate 
Unencumbered Property Values of the Unencumbered Properties located in 
the United Kingdom to exceed four percent (4%) of the Value of All 
Encumbered Properties, the amount in excess of said 4% level will be 
excluded when computing the Value of All Unencumbered Properties. 

     Variable Rate Indebtedness.  The Loans and all other Indebtedness

through maturity or for a term of at least thirty-six  (36) months from

entity involved, or (b) to control, manage or conduct the business of 
the corporation, partnership, association, trust or other business 
entity involved.

2.     TERM LOAN FACILITY.

     2.1.     Commitment to Lend.  Subject to the provisions of 10 and 
the other terms and conditions set forth in this Agreement, each of the 
Banks severally agrees to lend to the Borrower on the Closing Date the 
principal amount equal to such Bank's Commitment. Any amounts repaid 
pursuant to  3 may not be reborrowed.               

     2.2.     The Notes. The Loans shall be evidenced by separate 
promissory notes of the Borrower in substantially the form of Exhibit A 
hereto (each a "Note"), and completed with appropriate insertions.  One 
or more Notes shall be payable to the order of each Bank in an aggregate 
principal amount equal to such Bank's Commitment. The Borrower 
irrevocably authorizes each Bank to make or cause to be made, at or 
about the time of the Funding Date of any Loan or at the time of receipt 
of any payment of principal on such Bank's Note, an appropriate notation 
on such Bank's Record reflecting the making of such Loan or (as the case 
may be) the receipt of such payment. The Outstanding amount of the Loans 
set forth on such Bank's Record shall (absent manifest error) be prima 
facie evidence of the principal amount thereof owing and unpaid to such 
Bank, but the failure to record, or any error in so recording, any such 
amount on the Record shall not limit or otherwise affect the obligations 
of the Borrower hereunder or under any Note to make payments of 
principal of or interest on any Note when due.

     2.3.      Interest on Loans.

          (a)  Each Base Rate Loan shall bear interest for the period 
commencing with the Funding Date thereof and ending on the last day of 
the Interest Period with respect thereto at the Base Rate.

          (b)  Each Eurodollar Rate Loan shall bear interest for the 
period commencing with the Funding Date thereof and ending on the last 
day of the Interest Period with respect thereto at the rate equal to the 
Applicable Margin per annum above the Eurodollar Rate determined for 
such Interest Period.

          (c)  The Borrower unconditionally promises to pay interest on 
each Loan in arrears on each Interest Payment Date with respect thereto.

     2.4.      Interest Options .  The Loans advanced on the Closing 
Date shall be Eurodollar Rate Loans with an Interest Period of 6 months.  
After the expiration of such initial Interest Period, Outstanding Loans 
may be converted or continued as follows:

          (a) The Borrower may elect from time to time to convert any 
Outstanding Loan to a Loan of another Type, provided that (i) with 
respect to any such conversion of a Eurodollar Rate Loan to a Base Rate 
Loan, the Borrower shall give the Agent at least three (3) Business 
Days, prior written notice of such election; (ii) with respect to any 
such conversion of a Eurodollar Rate Loan into a Base Rate Loan, such 
conversion shall only be made on the last day of the Interest Period 
with respect thereto; (iii) subject to the further proviso at the end of 
this section and subject to 2.4(b) and 2.4(d) hereof with respect to any 
such conversion of a Base Rate Loan to a Eurodollar Rate Loan, the 
Borrower shall give the Agent at least four (4) Eurodollar Business 
Days, prior written notice of such election and (iv) no Loan may be 
converted into a Eurodollar Rate Loan when any Default or Event of 
Default has occurred and is continuing. On the date on which such 
conversion is being made, each Bank shall take such action as is 
necessary to transfer its Facility Percentage of such Loans to its 
Domestic Lending Office or its Eurodollar Lending Office, as the case 
may be. All or any part of Outstanding Loans of any Type may be 
converted as provided herein, provided further that each Conversion 
Request relating to the conversion of a Base Rate Loan to a Eurodollar 
Rate Loan shall be for an amount equal to $5,000,000 or an integral 
multiple of $1,000,000 in excess thereof and shall be irrevocable by the 
Borrower.

          (b) Any Loans of any Type may be continued as such upon the 
expiration of an Interest Period with respect thereto by compliance by 
the Borrower with the notice provisions contained in 2.4 (a) ; provided 
that no Eurodollar Rate Loan may be continued as such when any Default 
or Event of Default has occurred and is continuing but shall be 
automatically converted to a Base Rate Loan on the last day of the first 
Interest Period relating thereto ending during the continuance of any 
Default or Event of Default of which the officers of the Agent active 
upon the Borrower's account have actual knowledge.

          (c) In the event that the Borrower does not notify the Agent 
of its election hereunder with respect to any Loan, such Loan shall be 
automatically converted to a Base Rate Loan at the end of the applicable 
Interest Period.

          (d) The Borrower may not elect to convert a Base Rate Loan to 
a Eurodollar Rate Loan pursuant to 2.4(a) or elect to continue a 
Eurodollar Rate Loan pursuant to 2.4(b) if, after giving effect thereto, 
there would be greater than four (4) Eurodollar Rate Loans Outstanding. 
Any request for a Eurodollar Rate Loan that would create greater than 
four (4) Eurodollar Rate Loans Outstanding shall be deemed to be a 
request for a Base Rate Loan.

     2.5.     Funds for Loans .

          (a) Subject to 10 and other provisions of this Agreement, not 
later than 11:00 a.m. (Boston time) on the Closing Date, each of the 
Banks will make available to the Agent, at the Agent's Head Office, in 
immediately available funds, the amount of such Bank's Commitment. Upon 
receipt from each Bank of such amount, and upon receipt of the documents 
required by 10 and the satisfaction of the other conditions set forth 
therein, to the extent applicable, the Agent will make available to the 
Borrower the aggregate amount of such Loans made available to the Agent 
by the Banks. The failure or refusal of any Bank to make available to 
the Agent at the aforesaid time and place on the Closing Date the amount 
of its Commitment shall not relieve any other Bank from its several 
obligation hereunder to make available to the Agent the amount of such 
other Bank's Commitment but shall not obligate any other Bank or Agent 
to fund more than its Commitment or to increase its Commitment.

          (b) The Agent may, unless notified to the contrary by any Bank 
prior to the Closing Date, assume that such Bank has made available to 
the Agent on such Closing Date the amount of such Bank's Facility 
Percentage of the Loans to be made on such Closing Date, and the Agent 
may (but it shall not be required to), in reliance upon such assumption, 
make available to the Borrower a corresponding amount. If any Bank makes 
available to the Agent such amount on a date after such Closing Date, 
such Bank shall pay to the Agent on demand an amount equal to the 
product of (i) the average computed for the period referred to in clause 
(iii) below, of the weighted average interest rate paid by the Agent for 
federal funds acquired by the Agent during each day included in such 
period, times (ii) the amount of such Bank's Commitment, times (iii) a 
fraction, the numerator of which is the number of days or portion 
thereof that elapsed from and including such Closing Date to the date on 
which the amount of such Bank's Commitment shall become immediately 
available to the Agent, and the denominator of which is 365.  A 
statement of the Agent submitted to such Bank with respect to any 
amounts owing under this paragraph shall be prima facie evidence of the 
amount due and owing to the Agent by such Bank.

     
     3.     REPAYMENT OF THE LOANS.

     3.1.     Maturity . The Borrower unconditionally promises to pay on 
the Maturity Date, and there shall become absolutely due and payable on 
the Maturity Date, all of the Loans Outstanding on such date, together 
with any and all accrued and unpaid interest and charges thereon.

     3.2.      Optional Repayments of Loans . The Borrower shall have 
the right, at its election, to repay the Outstanding amount of the 
Loans, as a whole or in part, on any Business Day, without penalty or 
premium; provided that the full or partial prepayment of the Outstanding 
amount of any Eurodollar Rate Loans made pursuant to this 3.2 may be 
made only on the last day of the Interest Period relating thereto, 
except as set forth below in this 3.2. The Borrower shall give the Agent 
no later than 10:00 a.m., Boston time, at least three (3) Business Days' 
prior written notice of any prepayment pursuant to this 3.2 of any Base 
Rate Loans and four (4) Eurodollar Business Days, notice of any proposed 
repayment pursuant to this 3.2 of any Eurodollar Rate Loans, specifying 
the proposed date of payment of Loans and the principal amount to be 
paid.  The Agent shall promptly notify each Bank of the principal amount 
of such payment to be received by such Bank. Each such partial 
prepayment of the Loans shall be in an integral multiple of $1,000,000 
and shall be accompanied by the payment of all charges outstanding on 
all Loans and of accrued interest on the principal repaid to the date of 
payment and shall be applied, in the absence of instruction by the 
Borrower, first to the principal of Base Rate Loans and then to the 
principal of Eurodollar Rate Loans.  Notwithstanding anything contained 
herein to the contrary, the Borrower may make a full or partial 
prepayment of a Eurodollar Rate Loan on a date other than the last day 
of the Interest Period relating thereto, if all optional prepayments (in 
whole or in part) on such Loans shall be accompanied by, and the 
Borrower hereby promises to pay, a prepayment fee in an amount 
determined by the Agent in the following manner:

          (a)     Fixed Rate Prepayment Fee.  Borrower acknowledges that 
prepayment or acceleration of a Eurodollar Loan during an Interest 
Period shall result in the Banks incurring additional costs, expenses 
and/or liabilities and that it is extremely difficult and impractical to 
ascertain the extent of such costs, expenses and/or liabilities.  
Therefore, on the date a Eurodollar Rate Loan is prepaid or the date all 
sums payable hereunder become due and payable, by acceleration or 
otherwise ("Prepayment Date"), Borrower will pay to Agent, for the 
account of each Bank, (in addition to all other sums then owing), an 
amount ("Fixed Rate Prepayment Fee") determined by the Agent to be the 
amount, if any, by which (i) the amount of interest which would have 
accrued on the prepaid Eurodollar Rate Loan for the remainder of the 
Interest Period at the rate applicable to such Eurodollar Rate Loan 
exceeds (ii) the amount of interest that would accrue for the same 
period on any readily marketable bond or other obligation of the United 
States of America designated by the Agent in its sole discretion at or 
about the time of such payment, such bond or other obligation of the 
United States of America to be in an amount equal (as nearly as may be) 
to the amount of principal so paid and to have a maturity comparable to 
the remainder of such Interest Period, and the interest to accrue 
thereon to take account of amortization of any discount from par or 
accretion of premium above par at which the same is selling at the time 
of designation.

          (b)     Upon the written notice to Borrower from Agent, 
Borrower shall immediately pay to Agent, for the account of the Banks, 
the Fixed Rate Prepayment Fee.  Such written notice (which shall include 
calculations in reasonable detail) shall, in the absence of manifest 
error, be conclusive and binding on the parties hereto.

          (c)     Borrower understands, agrees and acknowledges the 
following:  (i) no Bank has any obligation to purchase, sell and/or 
match funds in connection with the use of the Eurodollar Rate as a basis 
for calculating the rate of interest on a Eurodollar Rate Loan; (ii) the 
Eurodollar Rate is used merely as a reference in determining such rate; 
and (iii) Borrower has accepted the Eurodollar Rate  as a reasonable and 
fair basis for calculating such rate and a Fixed Rate Prepayment Fee.  
Borrower further agrees to pay the Fixed Rate Prepayment Fee, if any, 
whether or not a Bank elects to purchase, sell and/or match funds.
  
     4.     CERTAIN GENERAL PROVISIONS.

     4.1.     Facility Fees, Arrangement Fee and Agent's Fee . The 
Borrower shall pay to the Agent for the account of each of the Banks 
facility fees in the amount of 50 basis points of such Bank's 
Commitment.  The Borrower shall pay to BankBoston arrangement fees and 
agency fees in the amounts specified in the fee agreement between 
BankBoston and the Borrower dated January 12, 1999. 


     4.2.     Funds for Payments .

          (a)      All payments of principal, interest, closing fees, 
commitment fees and any other amounts due hereunder (other than as 
provided in 4.1, 4.4 and 4.5) or under any of the other Loan Documents, 
and all prepayments, shall be made to the Agent, for the respective 
accounts of the Banks, at the Agent's Head Office, in each case in 
Dollars in immediately available funds.

          (b)  All payments by the Borrower hereunder and under any of 
the other Loan Documents shall be made without setoff or counterclaim 
and free and clear of and without deduction for any taxes, levies, 
imposts, duties, charges, fees, deductions, withholdings, compulsory 
liens, restrictions or conditions of any nature now or hereafter imposed 
or levied by any jurisdiction or any political subdivision thereof or 
taxing or other authority therein unless the Borrower is compelled by 
law to make such deduction or withholding.  If any such obligation is 
imposed upon the Borrower with respect to any amount payable by it 
hereunder or under any of the other Loan Documents, the Borrower shall 
pay to the Agent, for the account of the Banks or (as the case may be) 
the Agent, on the date on which such amount is due and payable hereunder 
or under such other Loan Document, such additional amount in Dollars as 
shall be necessary to enable the Banks or the Agent to receive the same 
net amount which the Banks or the Agent would have received on such due 
date had no such obligation been imposed upon the Borrower. The Borrower 
will deliver promptly to the Agent certificates or other valid vouchers 
for all taxes or other charges deducted from or paid with respect to 
payments made by the Borrower hereunder or under such other Loan 
Document.

     4.3.     Computations . All computations of interest on the Loans 
and of other fees to the extent applicable shall be based on a 360-day 
year and paid for the actual number of days elapsed. Except as otherwise 
provided in the definition of the term "Interest Period" with respect to 
Eurodollar Rate Loans, whenever a payment hereunder or under any of the 
other Loan Documents becomes due on a day that is not a Business Day, 
the due date for such payment shall be extended to the next succeeding 
Business Day, and interest shall accrue during such extension. The 
Outstanding amount of the Loans as reflected on the Records from time to 
time shall (absent manifest error) be considered correct and binding on 
the Borrower unless within thirty (30) Business Days after receipt by 
the Agent or any of the Banks from Borrower of any notice by the 
Borrower of such Outstanding amount, the Agent or such Bank shall notify 
the Borrower to the contrary.

     4.4.     Additional Costs, Etc. If any present or future applicable 
law which expression, as used herein, includes statutes, rules and 
regulations thereunder and interpretations thereof by any competent 
court or by any governmental or other regulatory body or official 
charged with the administration or the interpretation thereof and 
requests, directives, instructions and notices at any time or from time 
to time hereafter made upon or otherwise issued to any Bank or the Agent 
by any central bank or other fiscal, monetary or other authority 
(whether or not having the force of law), shall:

          (a)  subject any Bank or the Agent to any tax, levy, impost, 
duty, charge, fee, deduction or withholding of any nature with respect 
to this Agreement, the other Loan Documents, such Bank's Commitment or 
the Loans (other than taxes based upon or measured by the income or 
profits of such Bank or the Agent), or

          (b)  materially change the basis of taxation (except for 
changes in taxes on income or profits) of payments to any Bank of the 
principal of or the interest on any Loans or any other amounts payable 
to any Bank under this Agreement or the other Loan Documents, or

          (c)  impose or increase or render applicable (other than to 
the extent specifically provided for elsewhere in this Agreement) any 
special deposit, reserve, assessment, liquidity, capital adequacy or 
other similar requirements (whether or not having the force of law) 
against assets held by, or deposits in or for the account of, or loans 
by, or commitments of an office of any Bank, or

          (d)  impose on any Bank any other conditions or requirements 
with respect to this Agreement, the other Loan Documents, the Loans, the 
Commitment, or any class of loans or commitments of which any of the 
Loans or the Commitment forms a part;

and the result of any of the foregoing is

          (i) to increase the cost to such Bank of making, funding, 
issuing, renewing, extending or maintaining any of the Loans or such 
Bank's Commitment, or

          (ii) to reduce the amount of principal, interest or other 
amount payable to such Bank or the Agent hereunder on account of the 
Commitments or any of the Loans, or

          (iii) to require such Bank or the Agent to make any payment or 
to forego any interest or other sum payable hereunder, the amount of 
which payment or foregone interest or other sum is calculated by 
reference to the gross amount of any sum receivable or deemed received 
by such Bank or the Agent from the Borrower hereunder, 

then, and in each such case, the Borrower will, upon demand made by such 
Bank or (as the case may be) the Agent at any time and from time to time 
and as often as the occasion therefor may arise, pay to such Bank or the 
Agent, to the extent permitted by law, such additional amounts as will 
be sufficient to compensate such Bank or the Agent for such additional 
cost, reduction, payment or foregone interest or other sum.

     4.5.     Capital Adequacy. If any present or future law, 
governmental rule, regulation, policy, guideline or directive (whether 
or not having the force of law) or the interpretation thereof by a court 
or governmental authority with appropriate jurisdiction affects the 
amount of capital required or expected to be maintained by banks or bank 
holding companies and any Bank or the Agent determines that the amount 
of capital required to be maintained by it is increased by or based upon 
the existence of the Loans made or deemed to be made pursuant hereto, 
then such Bank or the Agent may notify the Borrower of such fact, and 
the Borrower shall pay to such Bank or the Agent from time to time on 
demand, as an additional fee payable hereunder, such amount as such Bank 
or the Agent shall determine in good faith and certify in a notice to 
the Borrower to be an amount that will adequately compensate such Bank 
or the Agent in light of these circumstances for its increased costs of 
maintaining such capital. Each Bank and the Agent shall allocate such 
cost increases among its customers in good faith and on an equitable 
basis.

     4.6.     Certificate. A certificate setting forth any additional 
amounts payable pursuant to 4.4 or 4.5 and a brief explanation of such 
amounts which are due, submitted by any Bank or the Agent to the 
Borrower, shall be prima facie evidence that such amounts are due and 
owing.

     4.7.     Indemnity.  In addition to the other provisions of this 
Agreement regarding any such matters, the Borrower agrees to indemnify 
each Bank and to hold each Bank harmless from and against any loss, cost 
or reasonable expense (including loss of anticipated profits) that such 
Bank may sustain or incur as a consequence of (a) a default by the 
Borrower in payment of the principal amount of or any interest on any 
Eurodollar Rate Loans as and when due and payable, including any such 
loss or expense caused by Borrower's breach or other default and arising 
from interest or fees payable by such Bank to lenders of funds obtained 
by it in order to maintain its Eurodollar Rate Loans, (b) a default by 
the Borrower in making conversion after the Borrower has given (or is 
deemed to have given) a Conversion Request, and (c) the making of any 
payment of a Eurodollar Rate Loan or the making of any conversion of a 
Eurodollar Rate Loan to a Base Rate Loan on a day that is not the last 
day of the applicable Interest Period with respect thereto, including 
interest or fees payable by such Bank to lenders of funds obtained by it 
in order to maintain any such Eurodollar Rate Loan.

     4.8.     Interest on Overdue Amounts. Overdue principal and (to the 
extent permitted by applicable law) interest on the Loans and all other 
overdue amounts payable hereunder or under any of the other Loan 
Documents shall bear interest compounded monthly and payable on demand 
at a rate per annum equal to four percent (4%) above the Base Rate until 
such amount shall be paid in full (after as well as before judgment). In 
addition, the Borrower shall pay to the Agent a late charge equal to 
three percent (3%) of any amount of principal and/or interest and/or 
charges on the Loans which is not paid within ten (10) days of the date 
when due.

     4.9     Inability to Determine Eurodollar Rate.  In the event, 
prior to the commencement of any Interest Period relating to any 
Eurodollar Rate Loan, the Agent shall determine that adequate and 
reasonable methods do not exist for ascertaining the Eurodollar Rate 
that would otherwise determine the rate of interest to be applicable to 
any Eurodollar Rate Loan during any Interest Period, the Agent shall 
forthwith give notice of such determination (which shall be conclusive 
and binding on the Borrower) to the Borrower. In such event (a) any 
Conversion Request with respect to Eurodollar Rate Loans shall be 
automatically withdrawn and shall be deemed a request for Base Rate 
Loans, (b) each Eurodollar Rate Loan will automatically, on the last day 
of the then current Interest Period thereof, become a Base Rate Loan, 
and (c) the obligations of the Banks to make Eurodollar Rate Loans shall 
be suspended until the Agent determines that the circumstances giving 
rise to such suspension no longer exist, whereupon the Agent shall so 
notify the Borrower.  

     4.10.     Illegality.  Notwithstanding any other provisions herein, 
if any present or future law, regulation, treaty or directive or in the 
interpretation or application thereof shall make it unlawful for any 
Bank to make or maintain Eurodollar Rate Loans, such Bank shall 
forthwith give notice of such circumstances to the Borrower and 
thereupon (a) the commitment of such Bank to make Eurodollar Rate Loans 
or convert Loans of another Type to Eurodollar Rate Loans shall 
forthwith be suspended and (b) the Eurodollar Rate Loans then 
Outstanding shall be converted automatically to Base Rate Loans on the 
last day of each Interest Period applicable to such Eurodollar Rate 
Loans or within such earlier period as may be required by law. The 
Borrower hereby agrees promptly to pay to the Agent for the account of 
such Bank, upon demand, any additional amounts necessary to compensate 
such Bank for any costs incurred by such Bank in making any conversion 
in accordance with this 4.10, including any interest or fees payable by 
such Bank to lenders of funds obtained by it in order to make or 
maintain its Eurodollar Rate Loans hereunder.

     4.11.     Replacement of Banks.  If any of the Banks shall make a 
notice or demand upon the Borrower pursuant to 4.4, 4.5, or 4.10 based 
on circumstances or laws which are not generally applicable to the Banks 
organized under the laws of the United States or any State thereof, the 
Borrower shall have the right to replace such Bank with an Eligible 
Assignee selected by the Borrower and approved by the Agent.  In such 
event the assignment shall take place on a date set by the Agent at 
which time the assigning Bank and the Eligible Assignee shall enter into 
an Assignment and Acceptance as contemplated by 18.1 (and clause (d) 
thereof shall not be applicable) and the assigning Bank shall receive 
from the Eligible Assignee or the Borrower a sum equal to the 
Outstanding principal amount of the Loans owed to the assigning Bank 
together with accrued interest thereon allocated to the assigning Bank.

     5.     UNENCUMBERED PROPERTIES; NO LIMITATION ON RECOURSE.

     5.1.     Listing of Unencumbered Properties .  The Borrower 
represents and warrants that each of the Real Estate Assets listed on 
Schedule 1.1 will on the Closing Date satisfy all of the conditions set 
forth in the definition of Unencumbered Property.  From time to time 
during the term of this Agreement additional Real Estate Assets may 
become Unencumbered Properties and certain Real Estate Assets which 
previously satisfied the conditions set forth in the definition of 
Unencumbered Property may cease to be Unencumbered Properties by virtue 
of property dispositions, creation of Liens or other reasons.  There 
shall be attached to each Compliance Certificate delivered pursuant to 
7.4(d) or 7.12 an updated listing of the Unencumbered Properties relied 
upon by the Borrower in computing the Value of All Unencumbered 
Properties and the Unencumbered Net Operating Income stated in such 
Compliance Certificate.

     5.2.      Waivers by Requisite Banks.  If any Real Estate Asset 
fails to satisfy any of the requirements contained in the definition of 
Unencumbered Property then the applicable Real Estate Asset may 
nevertheless be deemed to be Unencumbered Property hereunder if the 
Requisite Banks grant the necessary waivers and vote to accept such Real 
Estate Asset as an Unencumbered Property.

     5.3.     Rejection of Unencumbered Properties.  If at any time the 
Agent determines that any Real Estate Asset listed as an Unencumbered 
Property by the Borrower does not satisfy all of the requirements of the 
definition of Unencumbered Property (to the extent not waived by the 
Requisite Banks pursuant to 5.2) it may reject an Unencumbered Property 
by notice to the Borrower and if the Agent so requests the Borrower 
shall revise the applicable Compliance Certificate to reflect the 
resulting change in the Value of All Unencumbered Properties and the 
Unencumbered Net Operating Income.

     5.4.     Change in Circumstances.  If at any time during the term 
of this Agreement Borrower becomes aware that any of the representations 
contained in 6 are no longer accurate with respect to any Unencumbered 
Property, it will promptly so notify the Agent and either request a 
waiver pursuant to 5.2 or confirm that such Real Estate Asset is no 
longer an Unencumbered Property.  If any waiver so requested is not 
granted by the Requisite Banks within ten (10) Business Days the Agent 
shall reject the applicable Unencumbered Property pursuant to 5.3.

     5.5.     No Limitation on Recourse. The Obligations are full 
recourse obligations of the Borrower and, to the extent provided in the 
applicable Guaranty, of the Guarantors, and all of their respective Real 
Estate Assets and other properties shall be available for the 
indefeasible payment in full in cash and performance of the Obligations.  
Notwithstanding anything to the contrary contained herein, the trustees 
of Liberty Property Trust shall have no personal liability of any nature 
under this document.  The Agent and the Banks shall look solely to the 
assets of Liberty Property Trust to satisfy any liability or recourse 
against Liberty Property Trust hereunder.

     5.6.     Additional Guarantor Subsidiaries.  If Borrower desires 
that a Real Estate Asset owned by a Related Company which is not 
previously a Guarantor Subsidiary become an Unencumbered Property, then 
provided that the applicable Related Company is at least 85% owned by 
Borrower, such Related Company may become a Guarantor Subsidiary upon 
delivery to the Agent the following, all in form and substance 
satisfactory to the Agent: (a) a Guaranty in substantially the form of 
the Guaranty executed and delivered by the Guarantor Subsidiaries prior 
to the Closing Date, (b) good standing certificates, general partner 
certificates, secretary certificates, opinions of counsel and such other 
documents as may be reasonably requested by the Agent.  The Agent shall 
provide copies of said documents to the Banks.

Hazardous Materials.

Borrower's knowledge, operating in material compliance with such permits 
and applicable Environmental Laws. Notwithstanding that any 
representation contained herein may be limited to the knowledge of the 
Borrower, any such limitation shall not affect the covenants specified 
in 7.10 or elsewhere in this Agreement.

          (d)  None of the Real Estate is or shall be subject to any

Loan Documents are true and correct in all material respects.

     6.21.     Buildings on the Unencumbered Properties.  Except as set

material defects in the roof, foundation, structural elements and

plumbing or other mechanical systems which would materially decrease the 
value of such Unencumbered Property.

Borrower or its material vendors or property managers, will be able 
properly to recognize and perform date sensitive functions involving 
certain dates prior to and any date after December 31, 1999; (ii) 
developed a detailed plan and timetable to become Year 2000 Compliant in 
a timely manner; and (iii) committed adequate resources to support its 
Year 2000 plan. Based on such review and plan the Borrower reasonably 
believes that it will become Year 2000 Compliant on a timely basis 
except to the extent that a failure to do so will not have a Material 
Adverse Effect.

following events ("Events of Default" or, if the giving of notice or the

          (e)  any representation or warranty of the Borrower in this 
Agreement or any of the other Loan Documents or in any other document or 
instrument delivered pursuant to or in connection with this Agreement,

that with respect to the representations and warranties of the Borrower 
contained in 6.2, 6.3, 6.13, 6.18 and 6.21, if the condition or event 
making the representation and warranty false is capable of being cured 
by the Borrower, no enforcement action has been commenced against the 
Borrower or the applicable Unencumbered Property on account of such 
condition or event nor is the applicable Unencumbered Property subject 
to risk of forfeiture due to such condition or event, and the Borrower 
promptly commences the cure thereof after the Borrower's first obtaining 
knowledge of such condition or event, the Borrower shall have a period 
of thirty (30) days after the date that the Borrower first obtained 
knowledge of such condition or event during which the Borrower may cure 
such condition or event (or, if such condition or event is not 
reasonably capable of being cured within such thirty (30) day period, 
such additional period of time as may be reasonably required in order to 
cure such condition or event but in any event such period shall not 
exceed six (6) months from the date that the Borrower first obtained 
knowledge of such condition or event), and no Event of Default shall

giving of appropriate notice if required) the holder or holders thereof 
or of any obligations issued thereunder to accelerate the maturity 
thereof, and in any event, such failure shall continue for thirty (30) 
days, unless the aggregate amount of all such defaulted Recourse 
Indebtedness plus the amount of any unsatisfied judgments described in 
paragraph (i) of this 12.1 is less than $30,000,000.00;

          (g)  any of the Borrower, the Company or any Guarantor shall

or other custodian, liquidator or receiver of any substantial part of 
its properties or shall commence any case or other proceeding under any 
bankruptcy, reorganization, arrangement, insolvency, readjustment of 
debt, dissolution or liquidation or similar law of any jurisdiction, now 
or hereafter in effect, or shall take any action to authorize or in 
furtherance of any of the foregoing, or if any such petition or 
application shall be filed or any such case or other proceeding shall be 
commenced against any such Person and such Person shall indicate its 
approval thereof, consent thereto or acquiescence therein or any of the 
events described in this paragraph shall occur with respect to any other 
Related Company or any Permitted Joint Venture and such event shall have 
a Material Adverse Effect;

          (h)  a decree or order is entered appointing any such trustee, 
custodian, liquidator or receiver or adjudicating the Borrower, the 
Company, or any Guarantor bankrupt or insolvent, or approving a petition 
in any such case or other proceeding, or a decree or order for relief is 
entered in respect of the Borrower, the Company, or any Guarantor in an 
involuntary case under federal bankruptcy laws as now or hereafter 
constituted or any of the events described in this paragraph shall occur 
with respect to any other Related Company or any Permitted Joint Venture 
and such event shall have a Material Adverse Effect;

          (i)  there shall remain in force, undischarged, unsatisfied 
and unstayed, for more than thirty days, whether or not consecutive, any 
uninsured final judgment against the Borrower that, with other 
outstanding uninsured final judgments, undischarged, against the 
Borrower, the Company or any of the Related Companies plus the amount of 
any defaulted Recourse Indebtedness under paragraph (f) of this 12.1, 
exceeds in the aggregate $30,000,000.00;

          (j)  if any of the Loan Documents or any material provision of 
any Loan Documents shall be unenforceable, cancelled, terminated, 
revoked or rescinded otherwise than in accordance with the terms thereof 
or with the express prior written agreement, consent or approval of the 
Agent, or any action at law, suit or in equity or other legal proceeding 
to make unenforceable, cancel, revoke or rescind any of the Loan 
Documents shall be commenced by or on behalf of the Borrower or any 
Guarantor, or any court or any other governmental or regulatory

that, or issue a judgment, order, decree or ruling to the effect that, 
any one or more of the Loan Documents is illegal, invalid or 
unenforceable in accordance with the terms thereof;

          (k)  the Borrower or any Guarantor shall be indicted for a 
federal crime, a punishment for which could include the forfeiture of 
any assets of the Borrower;

          (l)  the Borrower shall fail to pay, observe or perform any 
term, covenant, condition or agreement contained in any agreement, 
document or instrument evidencing, securing or otherwise relating to any 
Indebtedness of the Borrower to any Bank (other than the Obligations) 
and/or relating to any Permitted Lien (other than the Obligations) 
within any applicable period of grace provided for in such agreement, 
document or instrument;

          (m)  any "Event of Default", as defined in any of the other 
Loan Documents, in the Revolving Credit Agreement or in the Subordinated 
Debenture Indenture, shall occur; then, and in any such event, so long 
as the same may be continuing, the Agent may, and upon the request of 
the Requisite Banks shall, by notice in writing to the Borrower declare 
all amounts owing with respect to this Agreement, the Notes and the 
other Loan Documents to be, and they shall thereupon forthwith become, 
immediately due and payable without presentment, demand, protest or 
other notice of any kind, all of which are hereby expressly waived by 
the Borrower; provided that in the event of any Event of Default 
specified in 12.1(g) or 12.1(h), all such amounts shall become 
immediately due and payable automatically and without any requirement of 
notice from the Agent or action by the Requisite Banks.

     12.2.      Remedies.  In case any one or more of the Events of 
Default shall have occurred, and whether or not the Requisite Banks 
shall have accelerated the maturity of the Loans pursuant to 12.1, each 
Bank, if owed any amount with respect to the Loans, may, with the 
consent of the Requisite Banks, direct the Agent to proceed to protect 
and enforce the rights and remedies of the Agent and the Banks under 
this Agreement, the Notes or any of the other Loan Documents by suit in 
equity, action at law or other appropriate proceeding, whether for the 
specific performance of any covenant or agreement contained in this 
Agreement and the other Loan Documents or any instrument pursuant to 
which the Obligations are evidenced and, if any amount shall have become 
due, by declaration or otherwise, to proceed to enforce the payment 
thereof or any other legal or equitable right of such Bank. No remedy 
herein conferred upon any Bank or the Agent or the holder of any Note is 
intended to be exclusive of any other remedy and each and every remedy 
shall be cumulative and shall be in addition to every other remedy given 
hereunder or now or hereafter existing at law or in equity or by statute 
or any other provision of law.

     12.3.     Distribution of Enforcement Proceeds.  In the event that, 
following the occurrence or during the continuance of any Default or 
Event of Default, the Agent or any Bank as the case may be, receives any 
monies in connection with the enforcement of any of the Loan Documents, 
such monies shall be distributed for application as follows:

          (a)  First, to the payment of, or (as the case may be) the 
reimbursement of the Agent for or in respect of all reasonable costs, 
expenses, disbursements and losses which shall have been incurred or 
sustained by the Agent in connection with the collection of such monies 
by the Agent, for the exercise, protection or enforcement by the Agent 
of all or any of the rights, remedies, powers and privileges of the 
Agent or the Banks under this Agreement or any of the other Loan 
Documents or in support of any provision of adequate indemnity to the 
Agent against any taxes or liens which by law shall have, or may have, 
priority over the rights of the Agent to such monies;

          (b)  Second, to all other Obligations in such order or 
preference as the Requisite Banks may determine; provided, however, that 
distribution in respect of such Obligations shall be made among the 
Banks pro rata in accordance with each Bank's respective Facility 
Percentage; and provided, further, that the Agent may in its discretion 
make proper allowance to take into account any Obligations not then due 
and payable;

          (c)  Third, upon payment and satisfaction in full or other 
provisions for payment in full satisfactory to the Requisite Banks and 
the Agent of all of the obligations, and to the payment of any 
obligations required to be paid pursuant to 9-504(1)(c) of the Uniform 
Commercial Code of the Commonwealth of Massachusetts; and

          (d)  Fourth, the excess, if any, shall be returned to the 
Borrower or to such other Persons as are legally entitled thereto.

     13.     SETOFF.  During the continuance of any Event of Default, 
any deposits (general or specific, time or demand, provisional or final, 
regardless of currency, maturity, or the branch of where such deposits 
are held) or other sums credited by or due from any of the Banks to the 
Borrower and any securities or other property of the Borrower in the 
possession of such Bank may be applied to or set off against the payment 
of Obligations and any and all other liabilities, direct, or indirect, 
absolute or contingent, due or to become due, now existing or hereafter 
arising, of the Borrower to such Bank. Each of the Banks agrees with 
each other Bank that (a) if an amount to be set off is to be applied to 
Indebtedness of the Borrower to such Bank, other than Indebtedness 
evidenced by the Notes held by such Bank, such amount shall be applied 
ratably to such other Indebtedness and to the Indebtedness evidenced by 
all such Notes held by such Bank, and (b) if such Bank shall receive 
from the Borrower, whether by voluntary payment, exercise of the right 
of setoff, counterclaim, cross action, enforcement of the claim 
evidenced by the Notes held by such Bank by proceedings against the 
Borrower at law or in equity or by proof thereof in bankruptcy, 
reorganization, liquidation, receivership or similar proceedings, or 
otherwise, and shall retain and apply to the payment of the Note or 
Notes held by such Bank any amount in excess of its ratable portion of 
the payments received by all of the Banks with respect to the Notes held 
by all of the Banks, such Bank will make such disposition and 
arrangements with the other Banks with respect to such excess, either by 
way of distribution, pro tanto assignment of claims, subrogation or 
otherwise as shall result in each Bank receiving in respect of the Notes 
held by it its proportionate payment as contemplated by this Agreement; 
provided that if all or any part of such excess payment is thereafter 
recovered from such Bank, such disposition and arrangements shall be 
rescinded and the amount restored to the extent of such recovery, but 
without interest.

     14.     THE AGENT.

     14.1.     Authorization .  The Agent is authorized to take such 
action on behalf of each of the Banks and to exercise all such powers as 
are hereunder and under any of the other Loan Documents and any related 
documents delegated to the Agent, together with such powers as are 
reasonably incident thereto, provided that no duties or responsibilities 
not expressly assumed herein or therein shall be implied to have been 
assumed by the Agent. The relationship between the Agent and the Banks 
is and shall be that of agent and principal only, and nothing contained 
in this Agreement or any of the other Loan Documents shall be construed 
to constitute the Agent as a trustee for any Bank.

     14.2.     Employees and Agents .  The Agent may exercise its powers 
and execute its duties by or through employees or agents and shall be 
entitled to take, and to rely on, advice of counsel concerning all 
matters pertaining to its rights and duties under this Agreement and the 
other Loan Documents. The Agent may utilize the services of such Persons 
as the Agent in its sole discretion may reasonably determine, and all 
reasonable fees and expenses of any such Persons shall be paid by the 
Borrower.

     14.3.     No Liability .  Neither the Agent nor any of its 
shareholders, directors, officers or employees nor any other Person 
assisting them in their duties nor any agent or employee thereof, shall 
be liable for any waiver, consent or approval given or any action taken, 
or omitted to be taken, in good faith by it or them hereunder or under 
any of the other Loan Documents, or in connection herewith or therewith, 
or be responsible for the consequences of any oversight or error of 
judgment whatsoever, except that the Agent or such other Person, as the 
case may be, may be liable for losses due to its willful misconduct or 
gross negligence.

     14.4.     No Representations .  The Agent shall not be responsible 
for the execution or validity or enforceability of this Agreement, the 
Notes, any of the other Loan Documents or any instrument at any time 
constituting, or intended to constitute, collateral security for the 
Notes, or for the value of any such collateral security or for the 
validity, enforceability or collectability of any such amounts owing 
with respect to the Notes, or for any recitals or statements, warranties 
or representations made herein or in any of the other Loan Documents or 
in any certificate or instrument hereafter furnished to it by or on 
behalf of the Borrower, or be bound to ascertain or inquire as to the 
performance or observance of any of the terms, conditions, covenants or 
agreements herein or in any instrument at any time constituting, or 
intended to constitute, collateral security for the Notes. The Agent 
shall not be bound to ascertain whether any notice, consent, waiver or 
request delivered to it by the Borrower or any holder of any of the 
Notes shall have been duly authorized or is true, accurate and complete. 
The Agent has not made nor does it now make any representations or 
warranties, express or implied, nor does it assume any liability to the 
Banks, with respect to the credit worthiness or financial condition of 
the Borrower. Each Bank acknowledges that it has, independently and 
without reliance upon the Agent or any other Bank, and based upon such 
information and documents as it has deemed appropriate, made its own 
credit analysis and decision to enter into this Agreement. Each Bank has 
been independently represented by separate counsel on all matters 
regarding this Agreement.

     14.5.     Payments .

          (a)  A payment by the Borrower to the Agent hereunder or any 
of the other Loan Documents for the account of any Bank shall constitute 
a payment to such Bank subject to the pro rata rights to repayment based 
upon the Facility Percentage of each Bank. The Agent agrees promptly to 
distribute to each Bank such Bank's pro rata share of payments received 
by the Agent for the account of the Banks except as otherwise expressly 
provided herein or in any of the other Loan Documents. 

          (b)  If in the opinion of the Agent the distribution of any 
amount received by it in such capacity hereunder, under the Notes or 
under any of the other Loan Documents might involve it in liability, it 
may refrain from making distribution until its right to make 
distribution shall have been adjudicated by a court of competent 
jurisdiction. If a court of competent jurisdiction shall adjudge that 
any amount received and distributed by the Agent is to be repaid, each 
Person to whom any such distribution shall have been made shall either 
repay to the Agent its proportionate share of the amount so adjudged to 
be repaid or shall pay over the same in such manner and to such Persons 
as shall be determined by such court.

          (c)  Notwithstanding anything to the contrary contained in 
this Agreement or any of the other Loan Documents, any Bank that fails 
(i) to make available to the Agent its pro rata share of any Loan or 
(ii) to comply with the provisions of 13 with respect to making 
dispositions and arrangements with the other Banks, where such Bank's 
share of any payment received, whether by setoff or otherwise, is in 
excess of its pro rata share of such payments due and payable to all of 
the Banks, in each case as, when and to the full extent required by the 
provisions of this Agreement, or to adjust promptly such Bank's 
outstanding principal and its pro rata Facility Percentage as provided 
in 2.1 hereof, shall be deemed delinquent (a "Delinquent Bank") and 
shall be deemed a Delinquent Bank until such time as such delinquency is 
satisfied.  A Delinquent Bank shall be deemed to have assigned any and 
all payments due to it from the Borrower, whether on account of 
Outstanding Loans, interest, fees or otherwise, to the remaining 
nondelinquent Banks for application to, and reduction of, their 
respective pro rata shares of all Outstanding Loans.  The Delinquent 
Bank hereby authorizes the Agent to distribute such payments to the 
nondelinquent Banks in proportion to their respective pro rata shares of 
all Outstanding Loans. A Delinquent Bank shall be deemed to have 
satisfied in full a delinquency when and if, as a result of application 
of the assigned payments to all Outstanding Loans of the nondelinquent 
Banks, the Banks' respective pro rata shares of all Outstanding Loans 
have returned to those in effect immediately prior to such delinquency 
and without giving effect to the nonpayment causing such delinquency.

     (d) If any amount which the Agent is required to distribute to the 
Banks pursuant to this 14.5 is actually distributed to any Bank on a 
date which is later than the first Business Day following the Agent's 
receipt of the corresponding payment from the Borrower, the Agent shall 
pay to such Bank on demand an amount equal to the product of (i) the 
average computed for the period referred to in clause (iii) below, of 
the weighted average interest rate paid by the Agent for federal funds 
acquired by the Agent during each day included in such period, times 
(ii) the amount of such late distribution to such Bank, times (iii) a 
fraction, the numerator of which is the number of days or portion 
thereof that elapsed from and including the second Business Day after 
the Agent's receipt of such corresponding payment from the Borrower to 
the date on which the amount so required to be distributed to such Bank 
actually is distributed, and the denominator of which is 365.

     14.6.     Holders of Notes.  The Agent may deem and treat the payee 
of any Note as the absolute owner or purchaser thereof for all purposes 
hereof until it shall have been furnished in writing with a different 
name by such payee or by a subsequent holder assignee or transferee.

     14.7.     Indemnity.  The Banks ratably agree hereby to indemnify 
and hold harmless the Agent from and against any and all claims, actions 
and suits (whether groundless or otherwise), losses, damages, costs, 
expenses (including any expenses for which the Agent has not been 
reimbursed by the Borrower as required by 15), and liabilities of every 
nature and character arising out of or related to this Agreement, the 
Notes, or any of the other Loan Documents or the transactions 
contemplated or evidenced hereby or thereby, or the Agent's actions 
taken hereunder or thereunder, except to the extent that any of the same 
shall be directly caused by the Agent's willful misconduct or gross 
negligence.

     14.8.     Agent as Bank.  In its individual capacity, BankBoston 
shall have the same obligations and the same rights, powers and 
privileges in respect to its Commitment and the Loans made by it, and as 
the holder of any of the Notes as it would have were it not also the 
Agent.

     14.9.     Resignation.  The Agent may resign at any time by giving 
sixty (60) days, prior written notice thereof to the Banks and the 
Borrower.  Upon any such resignation, the Requisite Banks shall have the 
right to appoint a successor Agent.  Unless a Default or Event of 
Default shall have occurred and be continuing, appointment of such 
successor Agent shall be subject to the reasonable approval of the 
Borrower.  If no successor Agent shall have been so appointed by the 
Requisite Banks and shall have accepted such appointment within thirty 
(30) days after the giving of notice of resignation or removal of the 
Borrower has disapproved or failed to approve a successor agent within 
such period, then the retiring Agent may, on behalf of the Banks, 
appoint a successor Agent, which shall be a financial institution having 
a rating of not less than A2/P2 or its equivalent by Standard & Poor's 
Corporation. Upon the acceptance of any appointment as Agent hereunder 
by a successor Agent, such successor Agent shall thereupon succeed to 
and become vested with all the rights, powers, privileges and duties of 
the retiring Agent, and the retiring Agent shall be discharged from its 
duties and obligations as Agent hereunder.  After any retiring Agent's 
resignation, the provisions of this Agreement and the other Loan 
Documents shall continue in effect for its benefit in respect of any 
actions taken or omitted to be taken by it while it was acting as Agent.

     14.10.  Notification of Defaults and Events of Default  and other 
Notices.  Each Bank hereby agrees that, upon learning of the existence 
of a Default or an Event of Default, it shall promptly notify the Agent 
thereof. The Agent hereby agrees that upon receipt of any notice under 
this 14.10, or upon it otherwise learning of the existence of a Default 
or an Event of Default, it shall promptly notify the other Banks of the 
existence of such Default or Event of Default.  The Agent shall also 
promptly provide each Bank with a copy of any notices which the Agent 
receives from the Borrower pursuant to 7.5 or 7.12.

     14.11.  Duties in the Case of Enforcement.  In case one of more 
Events of Default have occurred and shall be continuing, and whether or 
not acceleration of the Obligations shall have occurred, the Agent may, 
with the consent of the Requisite Banks (which consents may be obtained 
orally in emergency situations), and the Agent shall, if (a) so 
requested by the Requisite Banks and (b) the Banks have provided to the 
Agent such additional indemnities and assurances against expenses and 
liabilities as the Agent may reasonably request, proceed to enforce the 
provisions of the Loan Documents and exercise all or any such other 
legal and equitable and other rights or remedies as it may have. The 
Requisite Banks may direct the Agent in writing as to the method and the 
extent of any such enforcement actions, the Banks hereby agreeing to 
indemnify and hold the Agent harmless from all liabilities incurred in 
respect of all actions taken or omitted in accordance with such 
directions, provided that the Agent need not comply with any such 
direction to the extent that the Agent reasonably believes the Agent's 
compliance with such direction to be unlawful or commercially 
unreasonable in any applicable jurisdiction.

     14.12.  Mandatory Resignation of Agent.  In the event that the 
Agent enters into one or more Assignments pursuant to 18 having the 
effect of reducing the Agent's Facility Percentage to less than 10% then 
the Agent shall promptly so notify the Banks.  Upon the written request 
of any Bank whose Facility Percentage exceeds that of the Agent, which 
written request is made within thirty (30) days after the Agent's notice 
that its Facility Percentage is below such minimum level, the Agent 
shall be obligated to resign pursuant to 14.9.  Further, the Agent shall 
be obligated to resign pursuant to 14.9 upon the written request made 
for cause by Banks whose aggregate Facility Percentages constitute at 
least sixty-six percent (66%) of  the total Facility Percentages 
excluding the Facility Percentage of the Bank which is then the Agent 
hereunder.

     15.     EXPENSES.  The Borrower agrees to pay (a) the reasonable 
costs of producing and reproducing this Agreement, the other Loan 
Documents and the other agreements and instruments mentioned herein, (b) 
any taxes (including any interest and penalties in respect thereto) 
payable by the Agent or any of the Banks (other than taxes based upon 
the Agent's or any Bank's net income), including any recording, 
mortgage, documentary or intangibles taxes in connection with the Loan 
Documents, or other taxes payable on or with respect to the transactions

to indemnify the Banks with respect thereto), (c) all title examination 
costs, appraisal fees, engineers', inspectors' and surveyors' fees, 
recording costs and the reasonable fees, expenses and disbursements of

hereto or hereunder, (d) the fees, costs, expenses and disbursements of 
the Agent incurred in connection with the preparation, administration or 
interpretation of the Loan Documents and other instruments mentioned 
herein including without limitation, the costs incurred by the Agent in 
connection with its inspection of the Unencumbered Properties, and the 
fees and disbursements of the Agent's counsel and the Borrower's legal 
counsel in preparing documentation, (e) the fees, costs, expenses and 
disbursements of the Agent incurred in connection with the syndication

expenses (including reasonable attorneys' fees and costs, which 
attorneys may be employees of any Bank or the Agent and the fees and 
costs of appraisers, engineers, investment bankers, surveyors or other 
experts retained by the Agent or any Bank in connection with any such 
enforcement proceedings) incurred by any Bank or the Agent in connection 
with (i) the enforcement of or preservation of rights under any of the 
Loan Documents against the Borrower or the administration thereof after 
the occurrence of a Default or Event of Default (including, without 
limitation, expenses incurred in any restructuring and/or "workout" of 
the Loans), and (ii) any litigation, proceeding or dispute whether 
arising hereunder or otherwise, in any way related to the Agent's or the 
Bank's relationship with the Borrower, the Company, any Permitted Joint 
Venture or any of the Related Companies, (g) all reasonable fees, 
expenses and disbursements of the Agent incurred in connection with UCC 
searches, and (h) all costs incurred by the Agent in the future in 
connection with its inspection of the Unencumbered Properties. The 
covenants of this 15 shall survive payment or satisfaction of payment of 
amounts owing with respect to the Notes.

     16.     INDEMNIFICATION.  The Borrower agrees to indemnify and hold 
harmless the Agent and the Banks and the shareholders, directors, 
agents, officers, subsidiaries, and affiliates of the Agent and the 
Banks from and against any and all claims, actions or causes of action 
and suits whether groundless or otherwise, and from and against any and 
all Liabilities, losses, settlement payments, obligations, damages and 
expenses of every nature and character arising out of this Agreement or 
any of the other Loan Documents or the transactions contemplated hereby 
or which otherwise arise in connection with the financing including, 
without limitation except to the extent directly caused by the gross 
negligence or willful misconduct of a Bank or the Agent (but such 
limitation on indemnification shall only apply to the Agent or Bank 
being grossly negligent or committing willful misconduct), (a) any 
actual or proposed use by the Borrower of the proceeds of any of the 
Loans, (b) any actual or alleged infringement of any patent, copyright, 
trademark, service mark or similar right of the Borrower, (c) the 
Borrower entering into or performing this Agreement or any of the other 
Loan Documents or (d) with respect to the Borrower and its respective 
properties, the violation of any Environmental Law, the Release or 
threatened Release of any Hazardous Substances or any action, suit, 
proceeding or investigation brought or threatened with respect to any 
Hazardous Substances (including, but not limited to claims with respect 
to wrongful death, personal injury or damage to property), (e) any cost, 
claim liability, damage or expense in connection with any harm the 
Borrower may be found to have caused in the role of a broker, in each 
case including, without limitation, the reasonable fees and 
disbursements of counsel and allocated costs of internal counsel 
incurred in connection with any such investigation, litigation or other 
proceeding. In litigation, or the preparation therefor, the Banks and 
the Agent shall each be entitled to select their own separate counsel 
and, in addition to the foregoing indemnity, the Borrower agrees to pay 
promptly the reasonable fees and expenses of such counsel.  If, and to 
the extent that the obligations of the Borrower under this 16 are 
unenforceable for any reason, the Borrower hereby agrees to make the 
maximum contribution to the payment in satisfaction of such obligations 
which is permissible under applicable law. The provisions of this 16 
shall survive the repayment of the Loans and the termination of the 
obligations of the Banks hereunder and shall continue in full force and 
effect as to the Banks so long as the possibility of any such claim, 
action, cause of action or suit exists.

     17.     SURVIVAL OF COVENANTS, ETC.  All covenants, agreements, 
representations and warranties made herein, in the Notes, in any of the 
other Loan Documents or in any documents or other papers delivered by or 
on behalf of the Borrower or any Guarantor pursuant hereto shall be 
deemed to have been relied upon by the Banks and the Agent, 
notwithstanding any investigation heretofore or hereafter made by it, 
and shall survive the making by the Banks of the Loans, as herein 
contemplated, and shall continue in full force and effect so long as any 
amount due under this Agreement or the Notes or any of the other Loan 
Documents remains outstanding. The indemnification obligations of the 
Borrower provided herein and the other Loan Documents shall survive the 
full repayment of amounts due and the termination of the obligations of 
the Banks hereunder and thereunder to the extent provided herein and 
therein. All statements contained in any certificate or other paper 
delivered to the Agent or any Bank at any time by or on behalf of the 
Borrower pursuant hereto or in connection with the transactions 
contemplated hereby shall constitute representations and warranties by 
the Borrower hereunder.

     18.     ASSIGNMENT; PARTICIPATIONS; ETC.

     18.1.     Conditions to Assignment by Banks.  Except as provided 
herein, each Bank may assign to one or more Eligible Assignees all or a 
portion of its interests, rights and obligations under this Agreement 
(including all or a portion of its Facility Percentage and the same 
portion of the Loans at the time owing to it, and the Notes held by it); 
provided that (a) the Agent shall have given its prior written consent 
to such assignment, which consent shall not be unreasonably withheld or 
delayed, except that such consent shall not be needed with respect to an 
assignment from a Bank to either one of its Affiliated Banks or to 
another Bank hereunder, (b) each such assignment shall be of a portion 
of the assigning Bank's rights and obligations under this Agreement 
relating to a specified Facility Percentage, (c) each assignment shall 
be of Loans in an amount of not less than $10,000,000 (which number will 
be reduced in proportion to any partial prepayment of the Loans pursuant 
to 3.2) that is a whole multiple of $1,000,000, (d) each Bank either 
shall assign all of its Loans and cease to be a Bank hereunder or shall 
retain, free of any such assignment, an amount of its Outstanding Loans 
of not less than $10,000,000 (which number will be reduced in proportion 
to any partial prepayment of the Loans pursuant to 3.2), and (e) the 
parties to such assignment shall execute and deliver to the Agent, for 
recording in the Register (as hereinafter defined), an Assignment and 
Acceptance, substantially in the form of Exhibit E hereto (an 
"Assignment and Acceptance") , together with any Notes subject to such 
assignment.   Upon such execution, delivery, acceptance and recording, 
from and after the effective date specified in each Assignment and 
Acceptance, which effective date shall be at least five (5) Business 
Days after the execution thereof, (i) the assignee thereunder shall be a 
party hereto and, to the extent provided in such Assignment and 
Acceptance, have the rights and obligations of a Bank hereunder, and 
(ii) the assigning Bank shall, to the extent provided in such assignment 
and upon payment to the Agent of the registration fee referred to in 
18.3, be released from its obligations under this Agreement. So long as 
no Default or Event of Default has occurred and is continuing, 
Borrower's consent shall also be required for any assignment to an 
Eligible Assignee which is not at the time a Bank hereunder or one of 
such Bank's Affiliated Banks provided that Borrower's consent shall not 
be unreasonably withheld or delayed and shall not be withheld unless 
Borrower simultaneously designates an alternative Eligible Assignee 
(approved by the Agent) who agrees to accept an assignment of the 
interest which the assigning Bank proposed to assign and pay to such 
assigning Bank a sum equal to the Outstanding balance of principal and 
interest of Loans relating to the Facility Percentage being assigned. 
Assignments by BankBoston shall be exempt from the requirement in clause 
(c) above that assignments be of Loans in an amount which is a whole 
multiple of $1,000,000, the requirement that the effective date be at 
least five days after execution of the Assignment and Acceptance and the 
requirement for Borrower's consent and there shall be no registration 
fee with respect thereto under 18.3.

     18.2.     Certain Representations and Warranties; Limitations; 
Covenants.  By executing and delivering an Assignment and Acceptance, 
the parties to the assignment thereunder confirm to and agree with each 
other and the other parties hereto as follows: (a) other than the 
representation and warranty that it is the legal and beneficial owner of 
the interest being assigned thereby free and clear of any adverse claim, 
the assigning Bank makes no representation or warranty and assumes no 
responsibility with respect to any statements, warranties or 
representations made in or in connection with this Agreement or the 
execution, legality, validity, enforceability, genuineness, sufficiency 
or value of this Agreement, the other Loan Documents or any other 
instrument or document furnished pursuant hereto; (b) the assigning Bank 
makes no representation or warranty and assumes no responsibility with 
respect to the financial condition of the Borrower or any other Person 
primarily or secondarily liable in respect of any of the Obligations, or 
the performance or observance by the Borrower or any other Person 
primarily or secondarily liable in respect of any of the Obligations of 
any of their obligations under this Agreement or any of the other Loan 
Documents or any other instrument or document furnished pursuant hereto 
or thereto; (c) such assignee confirms that it has received a copy of 
this Agreement, together with copies of the most recent financial 
statements referred to in 6.4 and 7.4 and such other documents and 
information as it has deemed appropriate to make its own credit analysis 
and decision to enter into such Assignment and Acceptance; (d) such 
assignee will, independently and without reliance upon the assigning 
Bank, the Agent or any other Bank and based on such documents and 
information as it shall deem appropriate at the time, continue to make 
its own credit decisions in taking or not taking action under this 
Agreement, (e) such assignee represents and warrants that it is an 
Eligible Assignee; (f) such assignee appoints and authorizes the Agent 
to take such action as "Agent" on its behalf and to exercise such powers 
under this Agreement and the other Loan Documents as are delegated to 
the Agent by the terms hereof or thereof, together with such powers as 
are reasonably incidental thereto; (g) such assignee agrees that it will 
perform in accordance with their terms all of the obligations that by 
the terms of this Agreement are required to be performed by it as a 
Bank; and (h) such assignee represents and warrants that it is legally 
authorized to enter into such Assignment and Acceptance.  Each of the 
Syndication Banks shall be subject to the provisions of this 18.2 to the 
same extent as though it were becoming a party to this Agreement as an 
assignee by entering into an Assignment and Acceptance with BankBoston 
effective on the Closing Date.

     18.3     Register.  The Agent shall maintain a copy of each 
Assignment and Acceptance delivered to it and a register or similar list 
(the "Register") for the recordation of the names and addresses of the 
Banks and the Facility Percentages of, and principal amount of the Loans 
owing to the Banks from time to time. The entries in the Register shall 
be conclusive, in the absence of manifest error, and the Borrower, the 
Agent and the Banks may treat each Person whose name is recorded in the 
Register as a Bank hereunder for all purposes of this Agreement. The 
Register shall be available for inspection by the Borrower and the Banks 
at any reasonable time and from time to time upon reasonable prior 
notice.  Upon each such recordation, the assigning Bank agrees to pay to 
the Agent a registration fee in the sum of $2,500.00. The Agent may, 
without action by any other party, amend Schedules 1 and 1.2 hereof to 
reflect the recording of any such assignments.

     18.4.     New Notes.  Upon its receipt of an Assignment and 
Acceptance executed by the parties to such assignment, together with 
each Note subject to such assignment, the Agent shall (a) record the 
information contained therein in the Register, and (b) give prompt 
notice thereof to the Borrower and the Banks (other than the assigning 
Bank). Within five (5) Business Days after receipt of such notice, the 
Borrower, at its own expense, shall execute and deliver to the Agent, in 
exchange for each surrendered Note, a new Note to the order of such 
Eligible Assignee in an amount equal to the amount assumed by such 
Eligible Assignee pursuant to such Assignment and Acceptance and, if the 
assigning Bank has retained some portion of its Loans hereunder, a new 
Note to the order of the assigning Bank in an amount equal to the amount 
retained by it hereunder. Such new Notes shall provide that they are 
replacements for the surrendered Notes and that they do not constitute a 
novation, shall be in an aggregate principal amount equal to the 
aggregate principal amount of the surrendered Notes, shall be dated the 
effective date of such Assignment and Acceptance and shall otherwise be 
in substantially the form of the assigned Notes.  Within five (5) days 
of issuance of any new Notes pursuant to this 18.4, the Borrower shall 
deliver an opinion of counsel, addressed to the Banks and the Agent, 
relating to the due authorization, execution and delivery of such new 
Notes and the legality, validity and binding effect thereof, and that 
the Obligations evidenced by the new Notes have the same validity, 
enforceability and priority as if given on the Closing Date, in form and 
substance satisfactory to the Banks. The surrendered Notes shall be 
cancelled and returned to the Borrower.

     18.5.     Participations.  Each Bank may sell participations to one 
or more banks or other entities in a portion of such Bank's rights and 
obligations under this Agreement and the other Loan Documents not to 
exceed forty-nine percent (49%) of its Facility Percentage; provided 
that (a) the Agent shall have given its prior written consent to such 
participation, which consent shall not be unreasonably withheld or 
delayed, except that any Bank may sell participations to its Affiliated 
Banks without such consent, (b) each such participation, other than 
participations to its Affiliated Banks or to another Bank hereunder, 
shall be in an amount of not less than $10,000,000 that is a whole 
multiple of $1,000,000, (c) any such sale or participation shall not 
affect the rights and duties of the selling Bank hereunder to the 
Borrower and the Bank shall continue to exercise all approvals, 
disapprovals and other functions of a Bank, (d) the only rights granted 
to the participant pursuant to such participation arrangements with 
respect to waivers, amendments or modifications of the Loan Documents 
shall be the rights to approve the vote of the Bank as to waivers, 
amendments or modifications that would reduce the principal of or the 
interest rate on any Loans, extend the term or increase the amount of 
the Commitment of such Bank as it relates to such participant, reduce 
the amount of any fees to which such participant is entitled or extend 
any regularly scheduled payment date for principal or interest, provided 
that all approvals affecting a Loan or this Agreement under this clause 
(d) shall be by a fifty-one percent (51%) vote of such Bank's Facility 
Percentage, and (e) no participant which is not a Bank hereunder shall 
have the right to grant further participations or assign its rights, 
obligations or interests under such participation to other Persons 
without the prior written consent of the Agent. The Agent shall promptly 
advise the Borrower in writing of any such sale or participation.

     18.6.     Pledge by Lender.  Any Bank may at any time pledge all or 
any portion of its interest and rights under this Agreement (including 
all or any portion of its Note) to any of the twelve Federal Reserve 
Banks organized under 4 of the Federal Reserve Act, 12 U.S.C. 341. No 
such pledge or the enforcement thereof shall release the pledgor Bank 
from its obligations hereunder or under any of the other Loan Documents.

     18.7.     No Assignment by Borrower.  The Borrower shall not assign 
or transfer any of its rights or obligations under any of the Loan 
Documents without the prior written consent of each of the Banks, and 
any such attempted assignment shall be null and void.

     18.8.     Disclosure.  The Borrower agrees that in addition to 
disclosures made in accordance with standard banking practices any Bank 
may disclose information obtained by such Bank pursuant to this 
Agreement to assignees or participants and potential assignees or 
participants hereunder.

     19.     NOTICES, ETC.  Except as otherwise expressly provided in 
this Agreement, all notices and other communications made or required to

provisions hereof.

     22.     COUNTERPARTS.  This Agreement and any amendment hereof may 
be executed in several counterparts and by each party on a separate 
counterpart, each of which when so executed and delivered shall be an 
original, and all of which together shall constitute one instrument. In 
proving this Agreement it shall not be necessary to produce or account 
for more than one such counterpart signed by the party against whom 
enforcement is sought.

     23.     ENTIRE AGREEMENT.  The Loan Documents and any other 
documents executed in connection herewith or therewith express the 
entire understanding of the parties with respect to the transactions 
contemplated hereby. Neither this Agreement nor any term hereof may be

     24.     WAIVER OF JURY TRIAL AND CERTAIN DAMAGE CLAIMS.  THE 
BORROWER HEREBY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY 
ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS

AND OBLIGATIONS. EXCEPT TO THE EXTENT EXPRESSLY PROHIBITED BY LAW, THE 
BORROWER HEREBY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY 
LITIGATION REFERRED TO IN THE PRECEDING SENTENCE ANY SPECIAL, EXEMPLARY, 
PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN 
ADDITION TO, ACTUAL DAMAGES, AND THIS WAIVER INCLUDES, WITHOUT 
LIMITATION, ANY DAMAGES PURSUANT TO M.G.L. C. 93A ET SEQ. THE BORROWER 
(A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE AGENT OR 
ANY BANK HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE AGENT OR SUCH 
BANK WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE 
FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT THE AGENT AND THE BANKS HAVE 
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS 
TO WHICH THEY ARE PARTIES BY, AMONG OTHER THINGS, THE WAIVERS AND 
CERTIFICATIONS CONTAINED HEREIN.

     25.     CONSENTS, AMENDMENTS, WAIVERS, ETC.  Any consent or 
approval required or permitted by this Agreement may be given, and any 
term of this Agreement or of any other instrument related hereto or 
mentioned herein may be amended, and the performance or observance by 
the Borrower of any terms of this Agreement or such other instrument or 
the continuance of any Default or Event of Default may be waived (either 
generally or in a particular instance and either retroactively or 
prospectively) with, but only with, the written consent of the Requisite 
Banks, and, in the case of amendments, with the written consent of the 
Borrower other than amendments to schedules made in the ordinary course 
as contemplated by this Agreement. Notwithstanding the foregoing, (i)

Borrower or any Guarantor from its liability with respect to the 
Obligations, without first obtaining the written consent of all the 
Banks.  No waiver shall extend to or affect any obligation not expressly 
waived or impair any right consequent thereon. No course of dealing or 
delay or omission on the part of the Agent or any Bank in exercising any 
right shall operate as a waiver thereof or otherwise be prejudicial 
thereto. No notice to or demand upon the Borrower shall entitle the 
Borrower to other or further notice or demand in similar or other
