ITEM 5.   Other Events.

     On October 26, 1995, the registrant, executed a Contract of Sale
("Agreement") for the purchase of the land, building and improvements
(collectively the "Property") known as 580 Winter Street, Waltham,
Massachusetts.  The land consists of approximately 4.45 acres improved by an
80,000 s.f. single-story, brick building.

     580 Winter Street is owned by 580 Winter Street Corp., a Massachusetts
corporation having offices c/o Svenska Handlesbanken, 599 Lexington Avenue,
New York, New York  10022 (the "Seller").  There is no material relationship
between 580 Winter Street Corp. and the registrant or any of its affiliates,
any director or officer of the registrant, or any associate of any such
director or officer.

     One of the most important determinations by the registrant in connection
with its decision to purchase the Property was the environmental assessment. 
The Property is not completely free of all contaminants and is located near a
public drinking water supply.  The registrant's decision-making process is
summarized below, and that information is qualified in its entirety by the
materials filed as exhibits hereto.

     The Property is listed on the Massachusetts Department of Environmental
Protection's List of Confirmed Disposal Sites and Locations to be Inspected
("Investigation List").  The registrant has reviewed reports of environmental
engineers concerning their investigation of the Property.  These reports
indicate (i) the Property was placed on the Investigation List because heating
oil contaminated soil was found on the site when a 10,000 gallon oil tank was
removed in 1987 (the heating fuel was converted to natural gas), (ii) the
storage tank was intact (iii) approximately 190 cubic yards of contaminated
soil was removed, (iv) investigation was undertaken pursuant to the
Massachusetts Contingency Plan (v) a Notice of Audit Findings/Notice of
Non-Compliance ("Notice") asserted that an initial LSP Evaluation opinion
failed to identify the applicable groundwater category for the site, (vi) The
Notice to the Seller asserted that because of the site's proximity to the
Cambridge Reservoir, the appropriate water quality standard was RCGW-1, (vii)
The Notice noted that the levels of trichloroethene and Total Petroleum
Hydrocarbons exceeded the RCGW-1 standard, (viii) The Notice required, among
other things, submission of a revised LSP Evaluation Opinion indicating that a
release subject to notification requirements occurred or may have occurred at
the subject site and that further response actions are necessary, (ix)the
Licensed Site Professional submitted a revised opinion including groundwater
category identification and analysis of the levels of fuel oil and
trichloroethene in the groundwater (x) the revised opinion concluded that the
proper water quality for the site was not RCGW-1 because, among other things,
the site was downgradient from the reservoir and groundwater from the site
does not flow into the reservoir, and (xi) the Licensed Site Professional
Response Action Outcome Statement and supporting documentation concluded that
all compounds at the site were below the applicable standards, that no
significant risk is posed by the presence of residual contamination and that
the site meets the groundwater environmental requirements applicable thereto.

     Under the Massachusetts Contingency Plan, state inspection is performed
by "privatized inspectors" who become certified by the State as "Licensed Site
Professionals."  Their opinions may be audited by the Department of
Environmental Protection for a period of five years from the date of filing of
the Report.  According to the Licensed Site Professional interviewed by the
Registrant, specific regulations provide that sites located near wells and
water bearing aquifers used as public drinking water sources but which are
downgradient therefrom are not required to meet the RCGW-1 standard by virtue
of their proximity.  At the moment no such regulations have been written to
cover the similar situation relative to reservoirs.

     On the basis of its review of the foregoing materials, the registrant
has executed the Contract of Sale, which provides in part that the registrant
has examined various reports and correspondence related to this matter and is
fully satisfied with the testing, remediation, DEP disposition and
environmental conditions at the premises.

     The privatization of the environmental inspection and implementation
process, the highly sensitive nature of environmental laws, the importance of
protecting the public drinking water supplies and the evolution of the
application and interpretation of regulations under the Massachusetts
Contingency Plan are but a few of the areas of uncertainty facing the
registrant in making its decision.  The registrant has made the judgment to
rely on the findings of the License Site Professional--with whom the
registrant engaged in due diligence discussions at the site--that the site is
in compliance with all applicable requirements.  The registrant expects that
managing environmental issues will be an ongoing aspect of its property
management activities.

     The purchase price is Five Million Fifty Thousand Dollars
($5,050,000.00).  Of this amount,  Five Hundred Five Thousand Dollars
($505,000.00) has been paid to the escrow agent and counsel to Seller,
Sullivan & Worcester, a Registered Limited Liability Partnership and the
balance of which is due on the closing.  The closing is scheduled to take
place on December 28, 1995.  

     The registrant expects to use some of its current assets which may
include cash, cash equivalents, and/or marketable securities to fund the
entire acquisition, renovation, refurbishment and relocation costs (expected
to be in the approximate range of $9.0 million).

     The registrant expects that the cost of ownership and operation of the
building over the long term will be similar to what the registrant currently
pays for its present offices even though the new facility of approximately
80,000 s.f. will accommodate a substantial increase in the number of
employees.  The registrant's lease for its current space of approximately
46,000 s.f. expires in January 1997.

     The new Property is used as rental property by the Seller and as office
space by the tenants.  The registrant intends to use the Property primarily as
its world-wide headquarters and to lease portions of it to tenants from time
to time.  Two such tenants are leasing such space at the present time under
leases covering approximately 41,000 s.f.  One lease (covering approximately
15,000 s.f.) is for a term of fifteen and one half years commencing October
1994 (with two five year options).  The other lease is on its first (of two)
three year extension terms (which began in July 1995). 

     The operation of a facility by the registrant is a new area of endeavor
for the employees and involves the development and practice of new skills to
be done well.  Additionally, the accounting treatment of owned facilities is
significantly different and dependent on variable tax laws and accounting
standards.

     3.4  If any instrument for the payment of the Downpayment

     4.   Physical Condition; Personal Property; Operating
Pending Closing.

     4.1  Purchaser has made such examination of the operation,
income, expenses and physical condition of the Premises and the
legal, zoning, land use, environmental, toxic and hazardous
materials, water and sewer availability, development potential,
reclamation and other matters affecting or relating to this
transaction as Purchaser deemed necessary or as were required by
law, rule, regulation or otherwise or Purchaser has waived such
examination.  In entering into this Agreement, Purchaser has not
been induced by and has not relied upon any representations,
warranties, guarantees or promises, whether express or implied,
made by Seller or any agent, employee or other representative of
Seller or by any broker or any other person representing or
purporting to represent Seller, which are not expressly set forth
in this Agreement, whether or not any such representations,
warranties, guarantees, promises, or statements were made in
writing or orally.  Purchaser confirms that it has examined a
current environmental inspection report of the Premises prepared
by Environmental Science Services ("ESS"), and the correspondence
of Seller and ESS with the Massachusetts Department of
Environmental Protection ("DEP") concerning the conditions
described in such examination, and that Seller has afforded
Purchaser full opportunity to examine the premises and discuss
such matters with ESS.  Purchaser is fully satisfied with the
testing, remediation, DEP disposition and environmental
conditions at the Premises.

     4.2  The sale under this Agreement includes the following
fixtures and articles of personal property, to the extent
presently existing at the Premises and owned by Seller: heating,
ventilating and air conditioning equipment, plumbing and
electrical equipment and fixtures, carpets and other floor
coverings, curtains, drapes, blinds and related window
treatments, partitions, fire safety devices, and fire protection
and burglar alarm equipment.

     4.3  Between the date of this Agreement and Closing, Seller
shall not enter into any new lease affecting the premises, or
modify or amend any existing lease, provided that Seller shall
have the right to comply with and enforce the terms of any
existing Lease, to waive default by the tenant thereunder or to
exercise any rights and remedies of the Landlord thereunder,
including the right to terminate the Lease for default of the
tenant thereunder.  Seller shall have no obligation to extend the
term of any existing Lease.

     5.   Casualty and Eminent Domain

     5.1  Seller is responsible for any damage to the Premises,
other than for ordinary use, wear, tear and natural
deterioration, until the Closing.  If the Premises are damaged by
fire, vandalism, storm, flood or any other casualty between the
date of this Agreement and Closing, Seller shall promptly notify
Purchaser and the parties shall obtain an estimate of the cost of
repairing the damage from an unaffiliated contractor of their
mutual choice.  If the estimated cost is less than $50,000 Seller
shall repair the damage at Seller's expense, the Closing shall
take place as provided herein and Seller shall be entitled to
receive all insurance proceeds as a result of the casualty.  If
the estimated cost is more than $50,000, Seller shall forthwith
proceed to commence and complete the necessary repairs and the
Closing shall take place as provided herein; provided, however,
that if Seller has not commenced such repairs as of the scheduled
date of Closing or the repairs are reasonably estimated to take
more than four months after the Closing to complete, then, at
Purchaser's option, the Closing shall be delayed until the work
is completed,  or if the Closing shall occur, the Purchase Price
shall be reduced by an amount equal to the deductible on Seller's
insurance policy, and there shall be assigned to Purchaser at the
Closing, all of Seller's right, title and interest in and to the
remaining insurance proceeds to the extent such proceeds relate
to restoration and repair of the Premises to be conveyed
hereunder, net of such sums as have reasonably been expended by
Seller on such repairs.  In addition, at Closing, Seller shall
assign to Purchaser and Purchaser shall assume all construction
contracts for such repair and restoration, to the extent such
contracts are assignable and relate to the Premises to be
conveyed hereunder.  If, for any reason, insurance proceeds are
not received on account of the damage or destruction, the parties
shall agree upon the amount necessary to repair the damage, and
such amount shall be credited against the Purchase Price.  In
addition, if Seller's mortgagee does not release all or a portion
of such insurance proceeds, Seller shall credit against the
Purchase Price the amount of such proceeds withheld to the extent
that such proceeds relate to restoration and repair of the
Premises to be conveyed hereunder.

     5.2  If prior to Closing there shall be a taking of all or
any portion of the Premises by a governmental or other public
authority by eminent domain, condemnation or otherwise
(collectively "Condemnation") which shall prevent continued use
of the premises (to include a loss of all access of the remaining
portion of the Premises to a public highway or street) for
substantially the same purposes and substantially in the same
manner to substantially the same extent as prior to Closing (a
"Total Condemnation"), Purchaser shall either:

          5.2.1     Accept title to the premises pursuant to the
terms of this Agreement upon payment of the full Purchase Price
without any credit against or abatement of the Purchase Price by
reason of the Condemnation (except as hereinafter provided), but
with an assignment by Seller (without recourse or warranty) of
Seller's right, title and interest as owner of the Premises in
the award or awards resulting from the condemnation and in the
proceeds thereof, and Seller shall deliver to Purchaser at
Closing any such proceeds received by Seller; provided, however,
that if any such Condemnation award is payable to the holder of
any mortgage or other lien on the Premises, then the Purchase
Price shall be reduced by the amount of such Condemnation award
payable to such mortgagee; or

          5.2.2.    Terminate this Agreement, and upon such
election, Seller shall return any amounts theretofore paid on
account of the Purchase Price with any interest earned thereon,
and Seller and Purchaser shall be released and discharged from
any and all further liability and obligation under this
Agreement.

     5.3  If, prior to Closing, there shall be a Condemnation
other than a Total Condemnation, Seller shall assign and pay over
to Purchaser at Closing the entire proceeds of the payment by the
condemning authority and any right to receive the same and title
shall pass to Purchaser at Closing; provided, however, that if
any such Condemnation award has been paid to the holder of any
mortgage or any other lien on the Premises, then the Purchase
Price shall be reduced by the amount of such Condemnation award
payable to such mortgagee.

     5.4  The provisions of this Article shall survive the
Closing and are in lieu of the provisions of any otherwise
applicable statute.

     6.   Representations and Covenants of Parties.

          6.1  Seller makes the following representations:

               6.1.1     Seller is a corporation duly organized,
validly existing and in good standing under the laws of the state
of Massachusetts.

               6.1.2     Seller has full power, authority and

and such other documents on its part to be performed or observed.

               6.1.3     The execution and delivery by Seller of
this Agreement and all the other documents contemplated to be
delivered by it hereunder, and the performance and observance by
it of the terms of this Agreement and the other documents and
instruments on its part to be performed or observed, have been
duly authorized by all necessary action (corporate or otherwise),
including without limitation, all necessary administrative and
other governmental action, and do not contravene (i) any law,
rule, regulation, order, writ, judgment, award, injunction or

     8.   Adjustments

     8.1  The following shall be apportioned between Seller and
Purchaser as of the midnight prior to the Closing Date and net
thereof in favor of Seller or Purchaser ("Net Adjustment") shall
be paid by Purchaser or credited against the Purchase Price, as
the case may be:

          8.1.1     Permit and license fees of assignable permits
and licenses, if any, and inspection charges.

          8.1.2     Utility charges, based on the most recent
available meter readings, if final readings cannot be obtained as
of the Closing Date,  any unfixed utility charges based thereon
for the intervening period shall be apportioned on the basis of
such reading.

          8.1.3     value of fuel oil stored on the Premises, at
the price then charged by Seller's supplier, including any taxes;

          8.1.4     prepaid rents;

          8.1.5     permitted administrative charges, if any, on
tenants' security deposits;

          8.1.6     Real estate taxes on the basis of the fiscal
year for which assessed.  If the tax for the fiscal year in which
the Closing occurs has not been fixed as of the Closing Date,
then the apportionment thereof shall be based on the tax rate for
the next preceding year applied to the latest assessed valuation,
and the same shall be readjusted after Closing based upon the
actual taxes.

          8.1.7     Seller shall be entitled to any and all real
estate tax savings or refunds for the tax fiscal years ending
prior to the Closing Date.  If any proceeding for reduction of
the assessed valuation of the Premises has been or is hereafter
filed affecting a tax period containing any period prior to the
Closing Date, the net tax savings for such period shall be
apportioned as of the Closing Date.  If such proceeding was
commenced by Seller, it shall be continued by Seller's attorney
whose charges, fees and disbursements shall be paid pro rata by
the parties.  If, after the Closing Date, Purchaser receives any
such tax savings as a credit against taxes payable in a
subsequent tax period in lieu of a refund, Purchaser shall
promptly pay to Seller the pro-rata share of the net tax savings
to which Seller is entitled.  If any such tax savings received by
Purchaser result from any proceedings commenced by Purchaser,
Purchaser's attorneys charges, fees and disbursements shall be
paid pro rata by the parties.

          8.1.8     Water and sewer charges, based on the most
recent available meter readings, any unfixed meter charge and any
unfixed sewer rent based thereon for the intervening period,
shall be apportioned on the basis of such reading.

          8.1.9     wages, of all persons employed at the
Premises whose employment was not terminated at or prior to the
Closing.

          8.1.10    municipal license charges, if any.

          8.1.11    management fees of the managing agent of the
Premises, unless such managing agent's employment is terminated
at or prior to the Closing.

          8.1.12    Assessments, in accordance with the
provisions of Section 8.5.

          8.1.13    Payments required under any service contracts
not cancelled at or before Closing.

     8.2  Any errors or omissions made in computing
apportionments at Closing shall be corrected.  The provisions of
this Article 8 shall survive Closing.

     8.3  If any tenant is in arrears in the payment of rent on
the Closing Date, rents received from such tenant after the
Closing shall be applied in the following order of priority; (a)
first to the month preceding the month in which the Closing
occurred; (b) then to the month in which the Closing occurred;
(c) then to any month or months following the month in which the
Closing occurred; and (d) then to the period prior to the month
preceding the month in which the Closing occurred.  If rents or
any portion thereof received by Seller or Purchaser after the
Closing are payable to the other party by reason of this
allocation, the appropriate sum, less a proportionate share of
any reasonable attorneys' fees, costs and expenses of collection
thereof, shall be promptly paid to the other party, which
obligation shall survive the Closing.

     8.4  At Closing, certified or official bank checks payable
to the order of the appropriate State, City or County officer in
the amount of any applicable Massachusetts Realty Transfer Tax
and any other applicable excise, transfer and/or recording tax
payable by reason of the delivery or recording of the deed shall
be delivered by the party required by law or by this Agreement to
pay such excise, transfer and/or recording tax, together with any
required tax returns or affidavits duly executed and sworn to,
and such party shall cause any such checks and returns to be
delivered to the appropriate officer promptly after Closing. The
obligation to pay any additional tax or deficiency and any
interest or penalties thereon shall survive Closing.   At
Seller's option, Purchaser shall pay on Seller's behalf any such
tax imposed in the first instance on Seller and receive a credit
against the Purchase Price.

          8.4.1     If at the Closing Date, there may be any
other liens or encumbrances which Seller is obligated to pay and
discharge, including any outstanding mortgages, Seller may use
any portion of the balance of the Purchase Price to satisfy the
same, provided Seller shall simultaneously either deliver to
Purchaser title instruments in recordable form and sufficient to
satisfy such liens and encumbrances of record together with the
cost of recording or filing said instruments, or deposit with the
Title Company sufficient monies, acceptable to and required by it
to insure obtaining and the recording of such satisfactions and
the issuance of title insurance to Purchaser either free of any
such liens and encumbrances, or with insurance against
enforcement of same out of the Premises.  If requested at least
one (1) day prior to Closing, Purchaser agrees to provide at
Closing separate certified or cashier's checks or wire transfers
of Federal Funds for same day value as requested, aggregating not
more than the amount of the balance of the Purchase Price to
facilitate the satisfaction of any such liens or encumbrances. 
The existence of any such taxes or other liens and encumbrances
shall not be deemed objections to title if Seller shall comply
with the foregoing requirements.

     8.5  If, at Closing the Premises or any part thereof are
subject to any assessment or assessments for municipal
improvements (each, an "Assessment") which are or may become
payable in annual installments, the first installment of which is
than a charge or lien or has been paid, any installment payable
for the year in which the Closing takes place shall be adjusted
at the Closing, and Purchaser shall assume the obligation to pay
the unpaid installments of such Assessment which are to become
due and payable after Closing.

any objection to title,  Purchaser shall, not later than thirty
(30) days prior to Closing, provide Seller with a Notice (as
hereinafter defined) identifying such objection and specifying
the nature thereof ("Initial Notice").  Thereafter, Purchaser may
give Seller written Notice of objections to title arising after
the date of the Initial Notice, but shall have waived objection
to matters disclosed by the Title Company prior to such date.  If
no Notice of objections is timely given by Purchaser, Purchaser
shall accept title subject to any objections which may then
affect the Premises.  Seller shall be entitled to an adjournment
or adjournments of Closing for up to ninety (90) days to remove
any objection to title.

     10.2 If Seller shall be unable to convey title to the
Premises in accordance with the provisions of this Agreement, or
if Purchaser has other valid grounds for refusing to close,
whether by reason of liens, encumbrances or other objections to
title or otherwise, other than those subject to which Purchaser
is obligated to accept title hereunder, or if any of Seller's
representations or warranties shall not be true, or if Seller is
otherwise unable to comply with this Agreement for any reason
other than Seller's willful default (such matters, collectively
"Title Defects"), the sole remedy of Purchaser shall be to
terminate this Agreement and the sole liability of Seller shall
be to return or cause Escrow Agent to return the Downpayment to
Purchaser.  Upon such refund and reimbursement, this Agreement
shall be null and void and the parties shall be relieved of all
further obligations and liability other than any liability
arising under Article 11.  Seller shall not be required to bring
any action or proceeding or incur any expense to cure any Title
Defect or to enable Seller otherwise to comply with the
provisions of this Agreement, except that Seller shall discharge
any mortgage, monetary judgment or other lien in a liquidated
amount encumbering the premises.

     10.3 Seller shall give and Purchaser shall accept such title
as the Title Company or another reputable title insurance company
licensed in the State of Massachusetts will be willing to insure
in accordance with the standard form of fee title insurance
policy approved by the regulatory authorities of the State of
Massachusetts, subject only to the Permitted Encumbrances.

     10.4 Any unpaid water charges, sewer rents or other similar
charges, together with any interests and penalties thereon, and

title, together with the cost of recording or filing any
instruments necessary to discharge such liens or encumbrances of
record, may be paid out of the funds to be delivered by Purchaser
at Closing in payment of the Purchase Price.  Upon request of
Seller, Purchaser shall provide at Closing separate checks for
the foregoing payable to the order of such persons as Seller
shall designate.

     10.5 Purchaser shall take title subject to all notes or
notices of violations of law or municipal ordinances, orders or
requirements noted or issued by any governmental department
having authority as to lands, housing, buildings, fire, streets,
health, environmental and labor conditions affecting the
Premises.  Seller shall furnish Purchaser with any authorizations
necessary to make the searches that could easily disclose these
matters.

     10.6 Any transfer, franchise, license or other similar taxes
or liens on the Premises shall not be deemed an objection to
title if the Title Company issues or binds itself to issue its
fee owner's policy insuring Purchaser against collection of such
taxes or lien out of the Premises.

     10.7 Notwithstanding any other provision of this Agreement,
Purchaser shall have the option to waive Purchaser's objections
to all Title Defects and accept the Premises in its then present
condition with such title and performance as Seller can deliver
and to pay therefor the Purchase Price, without reduction or
abatement, provided that, if the Premises have been damaged by
fire or other casualty, Seller shall deliver and assign to
Purchaser any and all recovery and right of recovery under
existing policies of insurance covering such casualty.

     10.8 Seller and Purchaser agree that if the Closing shall
not occur as and when provided hereby due to the failure by
Purchaser to perform, satisfy or comply with any of the
obligations, provisions, terms, agreements or conditions of this
Agreement to be performed, satisfied or complied with by
Purchaser, Seller as its sole and exclusive remedy shall be
entitled to receive and retain the Downpayment and all other
amounts, if any, paid by Purchaser on account of the Purchase
Price or otherwise, including the interest accrued thereon, as
and for liquidated damages, which liquidated damages the parties
presently contemplate as being fair and reasonable under the
circumstances described in this Section.  As a special inducement
for the execution hereof by Seller, Purchaser covenants that it
shall not contest the amount of such liquidated damages or seek
the return of any such payments to or for the account of
Purchaser, or seek to prevent or delay payment to Seller of any
such payments.  Upon receipt of such liquidated damages by
Seller, neither party shall have any further rights hereunder or
otherwise against the other, except as set forth in Article 11.

     11.  Broker.  Seller and Purchaser each represent and
warrant that neither has dealt with any broker in connection with
the transaction contemplated by this Agreement other than
Whittier Partners ("Broker").  Purchaser agrees to pay Broker any
commission or other compensation due Broker in connection with
this transaction pursuant to Purchaser's separate agreement with
Broker.  Each party shall indemnify and hold harmless the other
from and against any costs, claims or expenses, including,
without limitation, attorneys' fees arising out of the breach by
such party of its representation, warranty and agreement
contained in this Article.  The provisions of this Article shall
survive Closing and any termination of this Agreement.

     12.  Integrated Contract.  It is understood and agreed that
all prior understandings and agreements between Seller and
Purchaser are merged in this Agreement, which alone fully and
completely expresses their agreement, and that the same is
entered into after full investigation, neither party relying upon
any statement, representation or covenant not embodied in this
Agreement.

     13.  No Memorandum of Contract of Sale.  The parties shall
not record this Agreement or any memorandum of this Agreement in
the Land Records.

account in escrow in its master escrow account at The Bank of New
York, 360 Park Avenue, New York, New York, until Closing or
sooner termination of this Agreement and shall pay over or apply
the Downpayment in accordance with the terms of this Article. 
Escrow Agent shall hold the Downpayment in an interest-bearing
account for the benefit of the parties.  Any interest received
shall be paid (a) to Purchaser, if the Closing shall take place
pursuant to this Agreement, or (b) in any other instance to the
party entitled to the Downpayment.  The party receiving the
interest shall pay any income taxes thereon.  The Social Security
or Federal Tax Identification numbers of the parties shall be
furnished to Escrow Agent upon request.  At Closing, the
Downpayment shall be paid by Escrow Agent to Seller.  If for any
reason Closing does not occur and either party gives Notice to
Escrow Agent demanding payment of the Downpayment, Escrow Agent
shall give prompt Notice to the other party of such demand.  If
Escrow Agent does not receive Notice of objection from such other
party to the proposed payment within 5 days after the giving of
such Notice, Escrow Agent is hereby authorized and directed to
make such payment.  If Escrow Agent does receive such Notice of
objection within such 5 day period or if for any other reason,
Escrow Agent in good faith shall elect not to make such payment,
Escrow Agent shall continue to hold such amount until otherwise
directed by Notice from the parties to this Agreement or a final,
nonappealable judgment, order or decree of a court.  However,
Escrow Agent shall have the right at any time to deposit the
Downpayment and the interest thereon with the clerk of a court in
the County in which the Premises are located and shall give
Notice of such deposit to Seller and Purchaser.  Upon such
deposit or other disbursement in accordance with the terms of
this Article, Escrow Agent shall be relieved and discharged of
all further obligations and responsibilities hereunder.

     16.2 The parties acknowledge that, although Escrow Agent is
holding the Downpayment for Seller's account, for all other
purposes Escrow Agent is acting solely as a stakeholder at their
request and for their convenience and that Escrow Agent shall not
be liable to either party for any act or omission on its part
unless taken or suffered in bad faith or in willful disregard of
this Agreement.  Seller and Purchaser jointly and severally agree
to defend, indemnify and hold Escrow Agent harmless from and
against all costs, claims and expenses (including reasonable
attorneys' fees) incurred in connection with the performance of
Escrow Agent's duties hereunder, except with respect to actions
or omissions taken or suffered by Escrow Agent in bad faith or in
willful disregard of this Agreement.

     16.3 Escrow Agent may act or refrain from acting in respect
of any matter referred to herein in full reliance upon and with
the advice of counsel which may be selected by it (including any
member of its firm) and shall be fully protected in so acting or
refraining from action upon the advice of such counsel.

     16.4 Escrow Agent acknowledges receipt of the Downpayment by
check subject to collection and Escrow Agent's agreement to the
provisions of this Article by signing in the place indicated on
this signature page of this Agreement.

     16.5 Escrow Agent or any member of its firm shall be
permitted to act as counsel for Seller in any dispute as to the
disbursement of the Downpayment or any other dispute between the
parties whether or not Escrow Agent is in possession of the
Downpayment and continues to act as Escrow Agent.

     IN WITNESS WHEREOF, this Agreement has been duly executed by
Seller and Purchaser as of the day and year first above written.

attorney's fees incurred by LESSOR in enforcing any and all obligations of

Building, the right, from time to time, without unreasonable interference with 
Tenant's office use: (a) to install, use, maintain, repair, replace and

Landlord's prior written consent, install in the Premises any water fountains, 
refrigerators, sinks or cooking equipment, provided that Landlord's consent

not be unreasonably withheld with respect to items designed for the
convenience 
of Tenant's employees and further provided that special venting or other
matters 
are not required in connection therewith.

Commencement Work pursuant to Section 7 hereof (the "Commencement Date").

Tenant shall be responsible for the payment of additional rent and all 
other charges hereunder beginning on the Commencement Date.  Tenant shall be 
responsible for the payment of Basic Annual Rent (hereinafter defined) on the 
Rent Commencement Date (hereinafter defined).  As used herein, the term
"lease year"    shall mean each twelve (12) month period during the 
Term,
commencing      on the Commencement Date.

3.1     Extension: So long as Tenant is not in default hereunder, and no
event has occurred which, with the passage of time, could ripen into 
default, Tenant shall have the option to extend the Term for two (2) extended 
terms of five (5) years each (the "Extended Terms").  The Extended Term(s)
shall 
commence immediately following the end of any then existing Term.  Tenant may 
exercise its option to extend for any Extended Term by giving written notice
to 
Landlord at any time during the then existing Term of the Lease, but no later 
than twelve (12) months prior to the end of the then existing Term.  All terms 
and conditions applicable during the Term shall apply during any Extended 
Term(s), except for Basic Annual Rent which shall be as provided below.  If 
Tenant fails to give such notice exercising its option for the Extended
Term(s) 
within the time provided above, time being of the essence, this Lease shall 
automatically expire at the end of the then existing Term (unless sooner 
terminated as provided herein).

4.      Basic Annual Rent: Security Deposit:

(a)     Tenant shall not be obliged to pay Basic Annual Rent for the first 
six (6) months of the first lease year of the Term, (ii) the first one (1)
month 
of the eleventh (11th) lease year of the Term, and (iii) the final two (2) 
months of the final year of the Term, as extended if applicable (collectively, 
the "Free Rent Period").  The day on which Basic Annual Rent shall be due
shall 
be known as the "Rent Commencement Date".

(b)     Tenant covenants to pay to Landlord, Basic Annual Rent as
follows:

Lease Years 1-10 - ($7.50 per square feet of rentable area)
- - $114,390.00 per annum, or $9,532.50 monthly; and

Lease Years 11-15.5 - ($9.50 per square feet of rentable
area) - $144,894.00 per annum, or $12,074.50 monthly.

Basic Annual Rent for the seventh month of the First Lease Year shall be 
payable on the execution of this Lease.

In the event of the commencement or termination of this Lease, other than 
on the first or last day of a calendar month, Basic Annual Rent, additional
rent 
and other charges shall be appropriately prorated for the portion of the month 
elapsed to the Commencement Date, or to and including the date of termination, 
as the case may be.

(c)     Tenant will pay the Basic Annual Rent, additional rent and all other 
charges due hereunder on the first day of each month in advance, without set-
off, counterclaim, deduction or demand, to Landlord at the address set forth 
below, or at such other place as is designated in writing from time to time by 
Landlord.

(d)     All payments of Basic Annual Rent, additional rent and all other 
charges due hereunder shall be made to the Landlord at c/o WASA Management, 30 
Federal Street, Boston, MA 02110, or such other address as Landlord may from 
time to time designate by notice to Tenant.

Landlord, may at the completion of Tenant's Work (as such term is defined 
in Section 7 hereof), measure the Premises.  Tenant's rentable area shall then 
be finally computed and notice thereof shall be provided to Tenant.  For the 
purpose of this Lease, Tenant's rentable area shall be the product of (i) the 
total usable area of the Premises excluding the portion of the Premises
located 
on the roof and (ii) 1.039.

4.1     Free Rent Restriction: This Lease provides for a Free Rent Period 
during which Tenant's liability for the payment of Basic Annual Rent at the
then 
normal monthly rate shall be suspended.  Tenant shall be credited with having 
paid all sums which would otherwise be due only if, at the end of the Term of 
the Lease, as it may have been extended hereunder, Tenant has fully,
faithfully, 
and punctually performed all of Tenant's obligations hereunder, including the 
payment of all additional rent and other charges (other than Basic Annual Rent 
during the Free Rent Period) and all other monetary obligations and Tenant
shall 
have, at the appointed time, surrendered the Premises in the physical
condition 
required by this Lease.  Tenant acknowledges that its right to receive credit 
for payment which would have otherwise been due for the Free Rent Period is 
absolutely conditioned upon Tenant's full, faithful and punctual performance
of 
its obligations under this Lease.  If Tenant defaults and does not cure within 
the applicable grace period, payments of Basic Annual Rent which would
otherwise 
have been due during the Free Rent Period shall immediately become due and 
payable in full and this Lease shall be enforced as if there were not such
Free 
Rent Period or other rent concessions.  In such case, Basic Annual Rent due
for 
the Free Rent Period shall be calculated based upon the full Basic Annual Rent 
payable under this Lease for such lease year.

4.2     Extended Term: If Tenant exercises its option to extend the Term of 
this Lease for any Extended Term, Tenant covenants to pay to Landlord, during 
such Extended Term of this Lease, Basic Annual Rent equal to fair market rent 
(for a five (5) year term determined as of the date which is twelve (12)
months 
prior to the end of the previously existing Term) for comparable space in 
buildings similar to the Building in the area of the City of Waltham in the 
vicinity of the Building, but in no event shall Basic Annual Rent for such 
Extended Term be less than the Basic Annual Rent for the immediately preceding 
lease year of the term (the "Basic Annual Rent Floor").  It is understood and 
agreed that fair market Basic Annual Rent for any Extended

Term, as determined in the manner hereinafter provided, need not be a 
single rate for the entire Extended Term, but rather may be stepped over the 
course of the Extended Term.

Landlord shall notify Tenant as to the proposed Basic Annual Rent for the 
Extended Term of this Lease at least ten (10) months prior to the end of the 
Term.  Landlord shall notify Tenant of Landlord's chosen appraiser together
with 
Landlord's notice as to Basic Annual Rent for the Extended Term proposed by 
Landlord.  If Tenant disputes the amount of Basic Annual Rent so established
by 
Landlord, Tenant shall either rescind its option to extend the Term or notify 
Landlord of Tenant's objection to said amount within thirty (30) days after
the 
receipt of Landlord's notice to Tenant, which notice shall be accompanied by
the 
name of one (1) appraiser if Tenant does not rescind its option.  Tenant's 
failure to notify Landlord of Tenant's rescission or objection shall
constitute 
Tenant's agreement to the Basic Annual Rent specified by Landlord.  If Tenant
so 
notifies Landlord of Tenant's objection, then the amount of Basic Annual Rent 
for each year of the Extended Term shall be decided by three (3) appraisers,
one 
(1) selected by Landlord, one (1) selected by Tenant, and one (1) selected by 
the first two (2) appraisers selected.  Each party shall pay for the appraiser 
selected by it and the cost of the third appraiser shall be divided equally 
between the parties.  In no event may any appraiser determine fair market rent 
to be less than the Basic Annual Rent Floor.

Each appraiser shall have at least ten (10) years experience in the 
management, ownership and/or appraisal of property similar to the Building in 
the City of Waltham.  If two (2) appraisers are able to agree upon the Basic 
Annual Rent for each year of the Extended Term, then the Basic Annual Rent
shall 
be as determined by said two (2) appraisers, but only if the determination of 
said two (2) appraisers is within ten percent (10%) of the determination of
the 
third appraiser for each year of the Extended Term.  If the foregoing
condition 
is not satisfied, or if no two (2) appraisers are able to agree upon Basic 
Annual Rent for each year of the Extended Term, the Basic Annual Rent for each 
year of the Extended Term shall be the average of the determination of all
three 
(3) appraisers, but only if the lowest determination is at least ninety
percent 
(90%) of the highest determination.  If this procedure cannot be followed 
because the lowest determination is not ninety percent (90%) of the highest 
determination, then the appraisers shall send a notice to Landlord and Tenant, 
setting forth their individual determinations, and the highest such 
determination for each year and the lowest such determination for each year 
shall be disregarded and the remaining determination for each year shall be 
deemed the Basic Annual Rent for each year of the Extended Term.

If any appraiser is not appointed as provided herein, either party may 
request that such appraiser be appointed by the President of the Boston Bar 
Association and the costs of any appraiser so appointed shall be equally
divided 
by Landlord and Tenant.

Basic Annual Rent for each Extended Term(s) -payable in equal monthly 
installments, in advance, on the first day of every month during each Extended 
Term(s).

ninety (90) days after the end of the computation year.

(b)     Tenant shall pay to Landlord, as additional rent for each calendar 
year, Tenant's proportionate share of Operating Costs.  Tenant's proportionate 
share of Operating Costs shall be 19.4%, determined by dividing 15,252, being 
the number of rentable square feet leased by Tenant, by 78,680, being the
number 
of rentable square feet in the Building.  Tenant's proportionate share of 
Operating Costs shall be subject to adjustment in the event the rentable

Operating Cost Statement.

If this Lease shall commence or terminate other than on the first or last 
day of a calendar year, Tenant shall be liable for only that portion of its 
proportionate share of Operating Costs for such calendar year represented by a 
fraction, the numerator of which is the number of days of the Term, as it may
be 
extended hereunder, which falls within the calendar year and the denominator
of 
which is three hundred sixty-five (365).

Any obligations under this Section of Tenant which shall not have been 
paid at the termination or earlier expiration of the Term of this Lease shall 
survive such termination or earlier expiration and shall be paid when and as

6.      Real Estate Taxes:

(a)     As used in this Section, these words and terms shall have the
following meanings:

assessments and betterments levied, assessed or imposed by any
governmental authority upon or against the Property or Building or payments in 
lieu thereof, including reasonable expenses, which shall include without 
limitation, fees of attorneys, appraisers and other consultants incurred in 
connection with any efforts to obtain abatements or reductions or to assure 
maintenance of Landlord's taxes for any tax fiscal year wholly or partially 
included in the Term.  If, at any time during the Term of this Lease, any tax
or 
excise on rents or other taxes, however described, are levied or assessed 
against Landlord with respect to the rent reserved hereunder, either wholly or 
partially in substitution for, or in addition to, real estate taxes assessed
or 
levied on the Property or Building, or payments in lieu thereof, such tax or 
excise on rents shall be included in Real Estate Taxes; however, Real Estate 
Taxes shall not include franchise, estate, inheritance, succession, capital 
levy, transfer, income or excess profits taxes assessed to Landlord.  Real 
Estate Taxes shall further not include interest, penalties, or late charges 
associated with any late payment of Real Estate Taxes by Landlord, unless
caused by Tenant.

(ii)    "Real Estate Tax Statement" shall mean a statement in writing signed 
by Landlord, setting forth the Real Estate Taxes paid by or to be paid for a 
specified computation period pursuant to this Section accompanied by a copy of 
the applicable tax bill.

(iii)   "Tax Year" shall mean the fiscal tax year of the City of Waltham, 
Massachusetts.

(b)     For each Tax Year during the Term of this Lease, Tenant shall
pay to Landlord, as additional rent, Tenant's proportionate share of Real 
Estate Taxes.  Tenant's proportionate share shall be 19.4%, determined by 
dividing 15,252, being the number of rentable square feet leased by Tenant, by 
78,680, being the number of rentable square feet in the Building.  Tenant's 
proportionate share of Real Estate Taxes shall be subject to adjustment in the 
event the rentable square footage leased by Tenant or the rentable square 
footage in the Building either increases or decreases.  Such amount shall be
due 
and payable fifteen (15) days following receipt by the Tenant of the Real
Estate 
Tax Statement for a tax period.

If this Lease shall commence or terminate other than on the first or last 
day of a Tax Year, Tenant shall be liable for only that portion of Real Estate 
Taxes in respect of such year represented by a fraction the numerator of which 
is the number of days of the Term which fall within the Tax Year and the 
denominator of which is three hundred sixty-five (365).

Any obligation under this Section of Tenant which shall not have been paid 
at the expiration of the Term of this Lease, as it may have been extended,
shall 
survive such expiration and shall be paid when and as the amount of the same 
shall be determined together with interest thereon at the rate set forth in 
Section 20(d) from the date the payment was first due to Landlord.

Tenant's proportionate share of Operating Costs and Real Estate Taxes 
shall be determined on the first day of the applicable calendar year for 
Operating Costs and the first day of the Tax Year for applicable Real Estate 
Taxes based on an application of the above-referenced fractions on such dates.

7.      Preparation for Occupancy:

(a)     Landlord's Work.  Prior to the Commencement Date, Landlord shall 
deliver the Premises in a "as is', "where is" condition except for Landlord's 
Pre-Commencement Work as described in Exhibit B attached hereto ("Landlord's 
Pre-Commencement Work").  Subject to delays due to governmental regulation, 
unusual scarcity of or inability to obtain labor or materials, labor 
difficulties, casualty, weather, or other causes reasonably beyond Landlord's 
control or attributable to Tenant's action or inaction, Landlord shall use 
reasonable speed and diligence in the construction of the work to be
undertaken 
by Landlord in the Premises, and shall use diligent efforts to deliver the 
Premises to Tenant within four (4) weeks after Landlord has obtained approval 
from the City of Waltham to undertake Landlord's Pre-Commencement Work. 
Subject 
to the delays specified in the preceding sentence, Landlord shall, at its own 
cost and expense, use reasonable speed and diligence to complete the work 
described in Exhibit B within six (6) months following the Commencement Date. 
("Landlord's Post Commencement Date Work").  Landlord's failure to complete 
Landlord's Pre-Commencement Work and/or Landlord's Post Commencement Date Work 
within the time periods specified herein, for any reason, shall not give rise
to 
any liability of Landlord hereunder, except for gross negligence or

wilful misconduct, shall not constitute a Landlord's default, shall not 
affect the validity of this Lease, and shall have no effect on the beginning
or 
end of the Term as otherwise determined hereunder or on Tenant's obligations 
associated therewith. (Landlord's Pre-Commencement Work and Landlord's Post 
Commencement Date Work shall hereinafter sometimes collectively be referred to 
as "Landlord's Work.")

Landlord's Post Commencement Date Work shall be treated as having been 
substantially completed on the date on which the work described in Exhibit "B" 
has been substantially completed except for minor items of construction work
and 
minor mechanical adjustments of equipment and fixtures which can be completed 
after occupancy has been taken without causing material interference with 
Tenant's use and occupancy of the Premises ("Punch List Items").

Landlord shall complete as soon as conditions practically permit all Punch 
List Items, and Tenant shall cooperate with Landlord in providing access as
may 
be required to complete such work in a normal manner.  Landlord shall permit 
Tenant access for installing Tenant's fixtures, communications systems,
computer 
equipment and appurtenances, and other equipment in portions of the Premises 
prior to substantial completion when it can be done without material 
interference with remaining work and with the maintenance of harmonious labor 
relations.

(b)     Tenant's Work.  Tenant will engage, at its expense (except as 
provided below), its own architect or engineer to produce plans and 
specifications ("Plans and Specifications") for the "build-out" of the
Premises

("Tenant's Work").  Without limiting the generality of the foregoing, Tenant's 
Work shall also include the construction of all (i) demising walls within or 
around the Premises; (ii) common bathrooms and the corridors leading thereto
and 
(iii) accessways leading to the Premises, excluding demising walls leading to

and testing of Tenant's emergency generator and associated fuel tank and (ii) 
the items of Tenant's Work which Tenant shall be required to remove from the 
Premises at the expiration or earlier termination of this Lease ("Tenant's 
Removal Items").  Landlord shall provide, at Tenant's expense, temporary power 
to the Premises from existing sources during construction of Tenant's Work.

Prior to the commencement of Tenant's Work, Tenant shall deliver the Plans 
and Specifications to Landlord for its written approval, which approval shall 
not be unreasonably withheld or delayed.  Landlord shall respond to Tenant's 
request for approval of its Plans and Specifications within ten (10) business 
days after receipt thereof; the failure of Landlord to respond within said 
period shall constitute approval of the Plans and Specifications.  In the
event 
that Landlord shall not approve the Plans and Specifications, Landlord shall 
notify Tenant of its objections thereto.  Landlord and Tenant shall thereafter 
work cooperatively and in good faith to reach agreement upon mutually
acceptable 
Plans and Specifications.  Landlord shall not be deemed to be unreasonably 
withholding its consent to the Plans and Specifications if, among other
things:

(I)     the Plans and Specifications do not contain sufficient detail to 
enable Landlord to evaluate the effect including, without limitation, noise, 
vibration, odor and emissions, on the Building and Landlord's other tenants of 
Tenant's installation and testing of Tenant's emergency generator and
associated 
fuel tank (the "Generator Effect");

(ii)    the Generator Effect will, in Landlord's reasonable judgment, place 
the safety of the Building or Landlord's other tenants at risk; or

(iii)   Tenant's Work will, in Landlord's reasonable judgment, negatively 
effect the exterior appearance of the Building.

If, despite diligent and good faith efforts, Landlord and Tenant are 
unable to agree upon the Plans and Specifications within thirty (30) days
after 
Tenant has first submitted the Plans and Specifications to Landlord, then
either 
party shall have the right to terminate this Lease upon written notice to the 
other within five (5) days after the end of such thirty (30) day period,
without 
further recourse to either party.  If Tenant shall so exercise its right to 
terminate this Lease, then Tenant shall immediately reimburse Landlord for (i) 
the cost of Landlord's Work through the date of termination and (ii) all 
compensation paid to The Niles Company and CB Commercial Real Estate Group in 
connection with this Lease.

applicable laws, regulations, building codes, and reasonable and prudent
design 
standards for a first-class building, (ii) does not in any manner affect the 
structural or exterior elements of the Building except as specifically
provided 
therein, and (iii) is in all respects compatible with the mechanical,
electrical 
and structural components and systems of the Building (including applicable 
loading limits).  Landlord's approval of the Plans and Specifications shall 
signify Landlord's consent to the work thereon only and shall not result in
any 
responsibility of Landlord concerning such work.

Tenant shall engage its own contractor, subject to Landlord's approval which 
approval shall not be unreasonably withheld or delayed, to perform Tenant's 
Work, at Tenant's sole cost and expense, and Tenant agrees to complete

Tenant to perform Tenant's Work shall be subject to Landlord's prior written 
approval which approval shall not be unreasonably withheld or delayed.  Tenant 
agrees not to create, incur or permit any lien or other obligation to exist 
against the Property or Landlord by reason of Tenant's Work and Tenant agrees
to 
hold Landlord harmless from and against any and all claims and demands by 
contractors or other third parties against the Property or Landlord relating
to 
or arising out of Tenant's Work.  Tenant will maintain insurance reasonably 
acceptable to Landlord during the performance of Tenant's Work, and copies of 
any such insurance policies will be provided to Landlord and any mortgagee of 
Landlord, naming Landlord and any such mortgagee of Landlord as additional

suspended 
or abated until the Premises (except Tenant's Work, the Improvements and 
Tenant's Property which are to be repaired by or at the expense of Tenant), 
shall have been restored as nearly as practicable to the condition in which
they 
were immediately prior to such fire or other casualty, provided that
restoration 
can be completed in accordance with applicable laws and regulations; provided, 
however that notwithstanding the foregoing, Tenant shall not be entitled to an 
abatement if the damage is by Tenant's Property and Improvements including, 
without limitation, any fuel tank or generator.  Landlord shall not be liable 
for delays in the making of any such repairs which are due to governmental 
regulations, casualties and strikes, unavailability of labor and materials,
and 
other causes beyond the control of Landlord, nor shall Landlord be liable for 
any inconvenience or annoyance to Tenant or injury to the business of Tenant 
resulting from reasonable delays in repairing such damage.  If the Premises
are 
damaged by fire or other casualty and said Premises shall not have been
restored 
to substantially the same condition which they were in prior to such fire or 
other casualty within one hundred eighty (180) days after such fire or other 
casualty or are not capable of being so restored, as reasonably determined- by 
an independent engineer selected by Landlord, then Tenant may terminate this 
Lease by notice to Landlord within fifteen (15) days after the end of said one 
hundred eighty (180) day period, without further recourse to either party.

(b)(i) If more than twenty-five percent (25%) of the Building is damaged by
such 
fire or other casualty, whether or not the Premises shall have been damaged by 
such fire or other casualty, or (ii) if more than fifty percent (50%) of the 
Premises is damaged by fire or other casualty, or (iii) if restoration cannot
be 
achieved on account of inadequate insurance proceeds, governmental
restrictions 
or otherwise, then this Lease and the Term hereof may be terminated at the 
election of Landlord by giving written notice of termination to the Tenant 
within sixty (60) days following such fire or other casualty, the termination 
date being specified in such notice as a date not less than thirty (30) days 
after the day on which such termination notice is given.  In the event of any 
such termination, this Lease and the Term hereof shall expire as of such 
effective termination date and the Basic Annual Rent shall be apportioned as
of 
such date.

14.     Condemnation - Eminent Domain:

(a)     If the Property, or any material part thereof, shall be taken or 
appropriated by eminent domain or shall be condemned for any public or quasi-
public use, or by reason of any transfer of all or any material part of the 
Building, or any

interest therein made in avoidance of such a taking or 'appropriation, or (by 
virtue of any taking, appropriation or condemnation) shall suffer any damage 
(direct, indirect or consequential) for which Landlord or Tenant shall be 
entitled to compensation, then (and in any such event) this Lease and the Term 
hereof may be terminated at the election of Landlord by giving a written
notice 
of termination to the Tenant within sixty (60) days following the date on
which 
Landlord shall have received notice of a taking, appropriation or
condemnation, 
or shall have effected such transfer.

If the entire Premises, or a portion thereof shall be so taken, appropriated, 
condemned or transferred, such that Tenant shall be precluded from effectively 
utilizing the Premises for its intended purpose, then (and in such event) this 
Lease and the Term hereof may be terminated at the election of Tenant by
giving 
a written notice of termination to Landlord within sixty (60) days following
the 
date on which Tenant shall have received notice of a taking, appropriation, 
condemnation, or on which Landlord shall have transferred such property.

Upon the giving of any such notice of termination by either Landlord or
Tenant, 
this Lease and the Term hereof shall terminate as of the date on which
Landlord 
or Tenant, as the case may be, shall be required to vacate any portion of the 
area so taken, appropriated or condemned or shall be deprived of the means of 
access thereto, provided, however, that Landlord in its notice of termination 
may elect to terminate this Lease and the Term hereof retroactively as of the 
date on which such taking, appropriation or condemnation became legally 
effective.  In the event of such termination, this Lease and the Term hereof 
shall expire as of such effective termination date and the Basic Annual Rent 
shall be apportioned as of such date.

(b)     If neither party elects to terminate this Lease and the Term hereof, 
Landlord shall, with reasonable diligence and at its expense (but only to the 
extent of the taking award recovered or recoverable and made available to 
Landlord by any mortgagees of the Building), restore the remainder of the 
Premises (but not the Improvements or any of Tenant's Property), as nearly as 
practicable to the condition thereof prior to such taking, appropriation or 
condemnation, in which event the Basic Annual Rent shall be adjusted in a
manner 
such that (i) a just proportion of the Basic Annual Rent, according to the 
nature and extent of the taking, appropriation or condemnation and the
resulting 
permanent injury to the Premises shall be permanently abated, and (ii) a just 
proportion of the remainder of the Basic Annual Rent, according to the nature 
and extent of the taking, appropriation or condemnation and the resultant
injury 
sustained by the Premises, shall be abated until what remains of the Premises 
(other than Tenant's Work, Improvements or any of Tenant's Property) shall
have 
been restored as fully as practicable for permanent use and occupation by
Tenant 
hereunder.  Landlord shall not be liable for any delays in such restoration 
which are due to governmental regulations, casualties, strikes, unavailability 
of labor or materials, or other causes beyond Landlord's control nor shall 
Landlord be liable for any inconvenience or annoyance to Tenant or injury to
the 
business of Tenant resulting from reasonable delays in such restoration.

Landlord expressly reserves to Landlord and Tenant hereby assigns to Landlord 
all rights to compensation and damages created, accrued or accruing by reason
of 
any taking, appropriation or condemnation, except for compensation

relating to Tenant's Property and for moving expenses, provided the same are 
separately awarded to Tenant without reduction of Landlord's award.

15.     Injury and Damage: Landlord shall not be liable for any injury or
damages 
to persons or property resulting from fire, explosion, falling plaster, steam, 
gas, electricity, electrical disturbance, water, rain or snow or leaks from
any 
part of the Building or from the pipes, appliances or plumbing works or from
the 
roof, street or subsurface or from any other place or by dampness or by any 
other cause of whatever nature, unless caused by or due to the act, omission, 
fault, negligence or misconduct of Landlord, or its agents, servants or 
employees; nor shall Landlord, its agents, servants or employees be liable for 
any such damage caused by other tenants or persons on the Property or caused
by 
construction operations of any private, public or quasi-public person; nor
shall 
Landlord be liable for any latent defect in the Premises or in the Building.

16.     Indemnification: Tenant hereby indemnifies and covenants to save
Landlord 
harmless from and against any and all claims, liabilities or penalties
asserted 
by or on behalf of any person, firm, corporation or public authority:

(i)     on account of or based upon any injury to person, or loss of or damage
to 
property, sustained or occurring on the Premises on account of or based upon
the 
act, omission, fault, negligence or misconduct of any person other than
Landlord 
or its servants, agents or employees;

(ii)    on account of or based upon any injury to persons, or loss of or
damage to 
property, sustained or occurring in or about the Property and other than on
the 
Premises (and, in particular, without limiting the generality of the
foregoing, 
on or about the elevators, stairways, public corridors, sidewalks, parking 
areas, concourses, arcades, approaches, area ways, roof or other
appurtenances and facilities used in connection with the Building or the 
Premises) arising out of the use and occupancy of the Building or the Premises 
by the Tenant or by any other person claiming by, through or under Tenant, and 
caused by the act, omission, fault, negligence or misconduct of Tenant or its 
servants, agents or employees, and in addition to and not in limitation of the 
foregoing subdivision (i); and

(iii)   on account of or based upon (including monies due on account of) any
work 
or thing whatsoever done (other than by Landlord or its contractors, or agents 
or employees of either) on the Premises during the Term and during the period
of 
time, if

any, prior to the Commencement Date when Tenant may have been given access to 
the Premises;

and, in respect of any of the foregoing, from and against all costs, expenses 
(including, without limitation, reasonable attorney's fees) and liabilities 
incurred in or in connection with any such claim, or any action or proceeding 
brought thereon.  If any action or proceeding be brought against Landlord by 
reason of any such claim, Tenant upon notice from Landlord shall at Tenant's 
expense resist and defend -such action or proceeding and employ counsel 
therefore reasonably satisfactory to Landlord, it being agreed that such
counsel 
as may act for insurance underwriters of Tenant engaged in such defense shall
be 
deemed satisfactory.

17.     Insurance:

(a)     Tenant covenants and agrees that from and after the date of delivery
of 
the Premises from Landlord to Tenant, and during the Term of this Lease,
Tenant 
will carry and maintain, at its sole cost and expense, the form of insurance 
hereinafter provided for:

(i)     Tenant shall keep in full force and effect Comprehensive General
Liability 
Insurance including Blanket Contractual, Personal Injury, Broad Form Property 
Damage, Products Liability, Completed Operations, Fire Legal Liability and 
Owned, Non-owned and Hired automobile coverages, naming Landlord and Tenant
and 
any designee of Landlord, as insured, with minimum limits of $1,000,000 for 
property damage, $1,000,000 for injury or death of one person and $3,000,000
for 
injury or death of more than one person in a single accident and from time to 
time thereafter shall not be less than such higher amounts as may reasonably
be 
required by Landlord for any and all claims for injury or damage to persons or 
property or for the loss of life or of property occurring upon, in or about
the 
Premises and the public portions of the Building used by Tenant, its
employees, 
agents, contractors, customers and invitees.  Tenant shall deposit a policy or 
policies of such insurance, or an approved certificate thereof issued by duly 
authorized agents or the carriers in question, with Landlord, at least ten
(10) 
days before the
Commencement Date and renewals of same and at least thirty (30) days prior to 
the expiration of any existing policies.  All such policies must provide that 
Landlord and any additional insured be provided with thirty (30) days prior 
written notice of cancellation, reduction, or material change by the insurer.

(ii)    Tenant shall keep in full force and effect All Risk insurance
including 
sprinkler leakage and floor and earthquake (if floor and earthquake exposure 
exists) and vandalism and malicious

mischief on a 100% replacement cost basis covering all contents, pictures and 
improvements.  Tenant shall deposit a policy or policies of such insurance, or 
an approved certificate thereof with Landlord, providing Landlord within
thirty 
(30) days notice of cancellation, reduction, or material change by the
insurer.

(iii)   Tenant shall keep in full force and effect Workers' Compensation
insurance 
as required by law and Employers' Liability coverage for a minimum of $100,000 
per occurrence.

(iv)    Tenant covenants to comply with any and all rules and regulations 
applicable to the Premises issued by the Board of Fire Underwriters or by any 
other body hereinafter constituted exercising similar functions and insurance 
companies writing policies covering the Premises.  Tenant shall pay all costs, 
expenses, claims, fines, penalties and damages imposed because of failure of 
Tenant to comply with this subsection (iv) and agrees to indemnify Landlord
from 
all liability with reference thereto.  Tenant shall, at its own cost and 
expense, procure and maintain each and every permit, license, certificate or 
other authorization and any renewals, extension or continuances of the same 
required in connection with lawful and proper use of the Premises for Tenant's 
business.

(b)     Tenant will not do, or omit to do, or keep anything in, upon or about
the 
Premises, the Building or any adjacent areas which may prevent the obtaining
of 
any fire, liability or other insurance upon or Written in connection with the 
Premises, the Building or such adjacent areas or which may make any such 
insurance void or voidable or otherwise invalidate the obligations of the 
insurer contained therein, or which may create any extra premiums or increase 
the rate of any such insurance over that normally applicable to office
buildings 
in the City of Waltham.  Tenant agrees to pay to Landlord, upon demand, the 
amount of any extra premiums or any increase in the rate of such insurance
which 
results from Tenant's use of the Premises, whether or not Landlord has
consented 
to such use.  In the event that the installation of Tenant's emergency
generator 
and associated fuel tank shall result in an increase in the rate of Landlord's 
insurance, than Tenant shall pay the amount of any such increase in insurance 
premium and such installation shall not give rise to an event of default 
hereunder.  If Tenant installs any electrical equipment in the Premises,
Tenant 
shall, at its expense, make whatever changes are necessary to comply with the 
requirements of the insurance underwriter or governmental authorities having 
jurisdiction, but such changes shall only be made in accordance with the 
provisions of this Lease.

(c)     Landlord agrees to maintain in force during the Term an all risk
property 
policy with 100% full replacement cost coverage.

18.     Waiver of Subrogation:

(a)     Tenant and Landlord covenant that with respect to all fire or extended 
coverage insurance carried by Tenant and Landlord in connection with the 
Premises or the Building, whether or not such insurance is required by the
terms 
of this Lease, such insurance shall provide for the waiver by the insurance 
carrier of any subrogation rights against the other party, its agents,
servants 
and employees under such party's insurance policies.

(b)     Notwithstanding any other provision of this Lease, (i) Landlord shall
not 
be liable to Tenant for any loss or damage, whether or not such loss or damage 
is caused by the negligence of Landlord, its agents, servants or employees, to 
the extent that such loss or damage is covered by valid and enforceable 
insurance carried by Tenant and containing subrogation waiver provisions 
pursuant to paragraph (a); and (ii) Tenant shall not be liable to Landlord for 
any loss or damage, whether or not such loss or damage is caused by the 
negligence of Tenant or its agents, servants or employees, to the extent that 
such loss or damage is covered by valid and enforceable insurance carried by 
Landlord and containing subrogation waiver provisions pursuant to paragraph
(a).

19.     Assignment, Mortgaging, Subletting:

(a)     Tenant covenants and agrees that neither this Lease, nor the Term, nor
the 
estate hereby granted, nor any interest herein or therein, will be assigned, 
mortgaged, pledged, encumbered or otherwise transferred, and that neither the 
Premises, nor any part thereof, will be encumbered in any manner by reason of 
any act or omission of Tenant, or used or occupied, or permitted to be used or 
occupied, by anyone other than Tenant and its employees, or for any use or 
purpose other than as above stated, or be sublet, or offered or advertised for 
subletting, without in each case, Landlord's prior written consent. 
Assignment 
shall include, without limitation, any transfer of the Tenant's interest in
the 
Lease by operation of law, merger or consolidation of the Tenant into any
other 
firm or corporation, and the transfer or sale of a controlling interest in 
Tenant, whether by sale of its capital stock or otherwise.  It is expressly 
understood and agreed that such consent may be withheld in Landlord's sole and 
absolute discretion; provided, however, Landlord's consent to a proposed 
assignment or subleasing shall not be unreasonably withheld or delayed.  
Landlord shall not be deemed to be unreasonably withholding its consent to
such 
a proposed assignment or subleasing if:

(a)     the proposed assignee or subtenant is not of a character consistent
with 
Tenant's use or the operation of a first-class office/retail building; or

(b)     the proposed assignee or subtenant is not of good character and 
reputation; or

(c)     the proposed assignee or subtenant does not possess adequate financial 
capability to perform the Tenant obligations as and when due or required; or

(d)     the proposed assignee or subtenant proposes to use the Premises (or
any 
part thereof) for a purpose other than the purpose for which the Premises may
be 
used as set forth in Section 2 hereof-, or

(e)     the character of the business to be conducted or the proposed use of
the 
Premises by the proposed assignee or subtenant shall (i) be likely to increase 
operating expenses for the Property beyond that which Landlord now incurs for 
use by Tenant, or (ii) violate or be likely to violate any provisions or 
restrictions contained herein relating to the use or occupancy of the
Premises; 
or

(f)     there shall be existing a default under this Lease as set forth in
Section 
20.

Tenant's request for consent shall include a copy of the proposed instrument
of 
assignment or sublease, if available, or else a statement of the proposed 
assignment or sublease in detail satisfactory to Landlord.  Landlord shall
have 
the option (but not the obligation), in lieu of granting its consent to a 
proposed assignment or sublease, to terminate the Lease, or that portion 
proposed to be assigned or subleased, effective upon the date of the proposed 
assignment or sublease by giving Tenant written notice of such termination.

Notwithstanding Landlord's consent to any assignment or sublease, the
liability 
of Tenant and of any guarantor of Tenant's obligations under this Lease shall 
remain primary and Landlord's acceptance of Basic Annual Rent, additional rent 
and other charges from persons other than Tenant shall not operate to
discharge 
or in any way diminish such liability.

In the event of any such assignment or subletting, Tenant shall deliver to the 
Landlord at the time of such assignment or subletting a written agreement from 
the assignee, or subtenant agreeing with Landlord to perform Tenant's 
obligations under the Lease.

If the Basic Annual Rent, additional rent and other charges payable to Tenant 
under such assignment or sublease exceed the Basic Annual Rent, the additional 
rent and other charges payable under this Lease, Tenant shall pay to Landlord, 
as additional rent, one half of the amount of the excess.  Landlord's
acceptance 
of a check in payment of any obligations of Tenant under this Lease from a 
person other than Tenant shall not be construed as an implied consent by 
Landlord to an assignment of this Lease or subletting under it.

Any assignment of this Lease made hereunder shall be upon the express
condition 
that the assignee and Tenant shall promptly execute, acknowledge and deliver
to 
Landlord an agreement in form and substance satisfactory to Landlord whereby
the 
assignee shall agree to be personally bound by the terms, covenants,

and conditions of this Lease on Tenant's part to be performed and whereby the 
assignee shall expressly agree that the provisions of this Section shall, 
notwithstanding such assignment or transfer, continue to be binding upon it
with 
respect to all future assignments and transfers.

Any sublease of the Premises, or any part thereof, shall be expressly subject
to 
the terms of this Lease and shall contain the agreement of the subtenant 
thereunder that, upon Landlord's written request, it will pay all rents under 
the sublease directly to Landlord.

The provisions of this Section shall also be applicable to any sublease or
assignment by any sublessee or assignee or other person(s) or entity deriving 
its interest through Tenant.

(b)     If this Lease shall be assigned, or if the Premises or any part
thereof be sublet or occupied by anybody other than Tenant and its employees, 
Landlord, after default by Tenant hereunder, may collect the rents from such 
assignee, subtenant or occupant, as the case may be, and apply the net amount 
collected to the Basic Annual Rent herein reserved, but no such assignment, 
subletting, occupancy or collection shall be deemed a waiver of the
requirements 
set forth in subparagraph (a) of this Section, the acceptance by Landlord of 
such assignee, subtenant or occupant, as the case may be, as a tenant, or a 
release of Tenant from the future performance by Tenant of its covenants, 
agreements and obligations contained in this Lease.  The consent by Landlord
to 
an assignment or subletting shall not in any way be construed to relieve
Tenant 
from obtaining the express consent in writing of Landlord to any further 
assignment or subletting.  No assignment, subletting or use of the Premises 
shall affect the purpose for which the Premises may be used as stated in
Section 
2.

(c)     The listing of any name other than that of Tenant, whether on the
doors of 
the Premises or on the Building directory, or otherwise, shall not operate to 
vest any right or interest in this Lease or in the Premises or be deemed to be 
the written consent of Landlord mentioned in this Section, it being expressly 
understood that any such listing is a privilege extended by Landlord revocable 
at will by written notice to Tenant.

(d)     Tenant further covenants and agrees that it will not sublease space
from 
or take an assignment of a lease covering space in the Building from any other 
Building tenant or sublease to or assign this Lease to any other Building 
tenant.

(e)     Any reasonable legal expenses incurred by Landlord by reason of any 
proposed assignment or subletting shall be paid by Tenant whether or not the 
transaction shall be consummated.

Notwithstanding anything contained herein to the contrary, so long as MFS 
Intelenet of Massachusetts, Inc. or any Related Entity (as hereafter defined)
is 
the Tenant in possession of the Premises, Tenant shall have right, without the 
consent or approval of Landlord, and without any recapture rights or right to 
excess rents of, or payments of any fees to, Landlord:

(i)     assign its interest in this Lease (a) to any corporation which is a 
successor to Tenant either by merger or consolidation, or (b) to a purchaser
of 
all or substantially all of Tenant's stock or assets, or (c) to a corporation
or 
other entity which shall directly or indirectly control, be under the control 
of, or be under common control with, MFS Intelenet of
Massachusetts, Inc. or MFS Communications Company, Inc. (any such entity being
a 
"Related Entity"), provided that any such assignee has a net worth greater
than 
the higher of the net worth of Tenant on (1) the date hereof or (2) the date
of 
such assignment, or

(ii)    sublease all or any portion of Premises to a Related Entity.

For purposes hereof, "control" shall be deemed to mean the direct or indirect 
ownership of more than fifty percent of the outstanding voting stock of a 
corporation or other majority equity and control interest if not a
corporation.  
Without limiting the foregoing, the collocation of telecommunications
equipment 
in the Premises not owned by Tenant shall not constitute a prohibited
assignment 
of sublease or require the consent of Landlord.

20.     Default:

(a)     If Tenant shall default in the payment of the Basic Annual Rent, 
additional rent, or any other charges or sums due hereunder and such default 
shall continue for ten (10) days (after notice from Landlord to Tenant; 
provided, however, that Landlord shall not be required to give such notice
more 
than one time in any Lease Year), or if Tenant shall default in the
performance 
of any other of its obligations and such default shall continue for thirty
(30) 
days after written notice thereof by Landlord to Tenant (except that if Tenant 
cannot reasonably cure any such default within said thirty (30) day period,
this 
period may be extended for a reasonable period of time not exceeding thirty
(30) 
additional days, provided that Tenant commences to cure such default within
the 
thirty (30) day period and proceeds diligently thereafter to effect such
cure), 
or if Tenant or the Guarantor (as such term is defined in Section 36 hereof) 
shall file a petition under any bankruptcy, insolvency law or code, or if such
a 
petition filed against Tenant or Guarantor is not dismissed within sixty (60) 
days, or if Tenant or Guarantor shall be adjudicated bankrupt or insolvent 
according to law, or if Tenant or Guarantor shall make any assignment for the 
benefit of creditors, or if Tenant or Guarantor shall file any petition
seeking 
a reorganization, arrangement or similar relief, or if a receiver, custodian, 
trustee or similar agent is appointed for all or a substantial portion of 
Tenant's or Guarantor's assets, or if Tenant's interest in this Lease is taken 
upon execution or other process of law in any action against Tenant or if the 
Guarantor shall attempt to rescind or terminate the Guaranty (as such term

is defined in Section 36 hereof), then Landlord may lawfully enter the
Premises 
and repossess the same as the former estate of Landlord, or terminate this
Lease 
by written notice to Tenant and. in either event, expel Tenant and those 
claiming through or under Tenant, and remove their effects, without being
deemed 
guilty of any manner of trespass and without prejudice to any other remedy
which 
Landlord may have for arrears of Basic Annual Rent and additional rent and
other 
charges and sums due hereunder or proceeding on account of breach of covenant, 
and upon entry or notice as aforesaid, this Lease shall terminate.

In addition, Tenant covenants, in case of any default by Tenant hereunder, to 
pay Landlord all costs of enforcing Landlord's rights under this Lease 
(including, without limitation, reasonable attorneys' fees and actual out-of-
pocket expenses), reletting expenses (including without limitation, the costs
to 
prepare the Premises for a new tenant) and brokerage fees, and in addition, 
liquidated damages of any one of the following elected by Landlord: (i) the 
amount by which, at the termination of the Lease, the then present value
(using 
as a discount factor the current interest rate on U.S. Treasury bills having a 
maturity equivalent to the unexpired Term of the Lease) of the aggregate of
the 
Basic Annual Rent (including, without limitation, the Real Estate Tax and 
Operating Cost payments -projected on the basis of experience under this
Lease) 
and other sums payable hereunder projected over a period from such termination 
until the normal expiration date of the Term, exceeds the then present value 
(using as a discount factor the current interest rate on U.S. Treasury bills 
having a maturity equivalent to the unexpired Term of the Lease) of the 
aggregate projected fair market rental value of the Premises for such period,
or 
(ii) an amount equal to the Basic Annual Rent, plus Operating Costs and Real 
Estate Tax payments projected on the basis of experience under this Lease not
so 
terminated (subject to off-set for net rents actually received from reletting 
after subtraction of the expenses of reletting), payable upon the due dates as 
specified herein.

(b)     Landlord may bring legal proceedings for the recovery of such damages,
or 
any installments thereof, from time to time at its election, and nothing 
contained herein shall be deemed to require Landlord to postpone suit until
the 
date when the Term of this Lease would have expired if it had not been 
terminated hereunder.

(c)     Nothing herein contained shall be construed as limiting or precluding
the 
recovery by Landlord from Tenant of any sums or damages (including, without 
limitation, reasonable attorney's fees and expenses) to which, in addition to 
the damages particularly provided above, Landlord may lawfully be entitled by 
reason of any default hereunder on the part of Tenant.  Landlord and Tenant 
agree that, for the purpose of computing liquidated damages, the Real Estate
Tax 
and Operating Cost payments for the period between the termination of this
Lease 
pursuant to this Section and the normal expiration date shall be computed by 
multiplying the Real Estate Tax and Operating Cost payment for the year 
immediately preceding the year in which termination occurs times the number of 
years and any fraction thereof

remaining of the full Term (as it may have been extended hereunder) hereby 
granted on the assumption that the amount of such Real Estate Tax and
Operating 
Cost payments for the immediately preceding year would have remained constant 
for each subsequent year during the entire Term of this Lease (as it may have 
been extended hereunder).  This same principle shall apply to the twelve (12) 
month period following termination if Landlord shall elect to recover under 
(iii) above.  If this Lease and the Term shall terminate pursuant to this 
Section prior to the determination of the initial Real Estate Tax and
Operating 
Cost payments, such payments shall be reasonably estimated by Landlord, at its 
sole discretion.  Landlord shall not be obligated to mitigate its damages, but 
shall market the Premises for lease with the broker then marketing space in
the 
Building.

(d)     Payments of Basic Annual Rent, additional rent, Real Estate Taxes, 
Operating Cost payments and any other obligations of Tenant which are not paid 
on the date due shall, at the option of Landlord, bear interest at the rate 
equal to the "Base Rate" from time to time established by The First National 
Bank of Boston, plus two (2) percent per annum from the due date.

21.     Landlord's Right to Cure: If Tenant shall default in the observance or 
performance of any term, covenant or condition on its part to be observed or 
performed under this Lease, Landlord, without being under any obligation to do 
so and without thereby waiving such default, may remedy such default for the 
account and at the expense of Tenant, immediately and without notice in case
of 
emergency, or in any other case, if Tenant shall fail to remedy such default 
with all reasonable diligence within the time set forth under Section 20 and 
after Landlord shall have notified Tenant of such default.  If Landlord makes 
any expenditures or incurs any obligations for the payment of money in 
connection therewith, including, but not limited to, reasonable attorney's
fees, 
such sums paid or obligations incurred, with interest at the rate of interest 
set forth in Section 20(d), shall be paid to Landlord by Tenant as additional 
rent hereunder.

22.     Subordination: This Lease is subject and subordinate in all respects
to 
all existing mortgages and ground leases and other matters of record and, 
provided Tenant is provided with a so-called non-disturbance agreement to all 
mortgages and ground leases which may hereafter be placed on or affect this 
Lease, the Property, or Landlord's interest or estate therein, and to each 
advance made or hereafter to be made under any such mortgages, and to all 
renewals, modifications, consolidations, replacements and extensions thereof
and 
all substitutions therefor.  This Section shall be self-operative and no
further 
instrument of subordination shall be required.  In confirmation of such 
subordination, Tenant shall execute and deliver promptly any certificate 
acknowledging or confirming such subordination that Landlord or any mortgagees 
or their respective successors in interest may request.  Notwithstanding the 
foregoing, any mortgagee may elect at any time to subordinate its mortgage to 
this Lease in whole or in part.  In the event of an assignment to any
mortgagee 
of this Lease or any payments due hereunder, such mortgagee shall have no 
liability for Landlord's obligations unless the

same shall have been expressly assumed in writing by such mortgagee or unless 
such mortgagee shall have obtained indefeasible title to the Property.  No act 
or failure to act on the part of Landlord which would entitle Tenant under the 
terms of this Lease, or by law, to be relieved of Tenant's obligations
hereunder 
or to terminate this Lease shall result in such release or termination unless

transfers 
of title to said Property, the Landlord herein named (and in case of any

subsequent transfers or conveyances, the then grantor) shall be automatically 
relieved from and after the date of such transfer or conveyance of all
liability 
as respects the performance of any covenants or obligations on the part of the 
Landlord contained in this Lease thereafter to be performed, it being intended 
hereby that the covenants and obligations contained in this Lease on the part
of 
Landlord shall, subject as aforesaid, be binding on the Landlord, its
successors 
and- assigns, only during and in respect of their respective successive
periods 
of ownership of the Property.  Tenant, its successors and assigns, agrees it 
shall not assert nor seek to enforce any claim for breach of this Lease
against 
any of Landlord's assets other than Landlord's interest in the Property and in 
the rents, issues and profits thereof, and Tenant agrees to look solely to
such 
interest for the satisfaction of any liability of or claim against Landlord 
under this Lease, it being specifically agreed that in no event whatsoever
shall 
Landlord (which term shall include, without limitation, any beneficiary of any 
trust of which Landlord is a trustee or any general or limited partners of 
Landlord if Landlord is a general or limited partnership), ever be personally 
liable for any such liability.  In no event shall Landlord be liable for any 
indirect or consequential damages, including without limitation, loss of 
profits, loss of business, damage to reputation or loss of rental under any 
sublease or assignment arrangement.  Nothing contained herein shall prohibit
any 
action by Tenant against Landlord for, specific performance.

notice 
of this
Lease in such recordable form as may be permitted by applicable statute.

30.     Brokerage: Landlord and Tenant each represents and warrants to the
other 
that it has dealt with no broker except The Niles Company and CB Commercial
Real 
Estate Group, Inc. in connection with this transaction.  Landlord hereby
agrees 
to pay all compensation which may be due by it to The Niles Company and CB 
Commercial Real Estate Group, Inc. as set forth in a separate agreement. 
Tenant 
agrees to hold harmless and indemnify Landlord from and against any and all 
costs, (including without limitation reasonable attorneys' fees), expenses, or 
liability for any compensation, commissions and/or charges claimed by any
other 
broker or agent claiming to have dealt with Tenant in connection with this
Lease 
or the negotiation thereof.

31.     Claims in Bankruptcy: Nothing herein shall limit or prejudice the
right of 
Landlord to prove and obtain in a proceeding for bankruptcy, insolvency, 
arrangement or reorganization, by reason of the termination, an amount equal
to 
the maximum allowed by a statute of law in effect at the time when, and 
governing the proceedings in which, the damages are to be proved, whether or
not 
the amount is greater to, equal to, or less than the amount of the loss or 
damage which Landlord has suffered.

32.     Estoppel Certificates: At Landlord's request, from time to time,
Tenant 
agrees to execute and deliver to Landlord within ten (10) days after requested 
to do so by Landlord, a certificate which acknowledges tenancy and possession
of 
the Premises and recites such other facts concerning any provision of the
Lease 
or payments made under the Lease including, without limitation, the date to 
which rents have been paid, the amount of any security deposit, and whether 
Landlord is then in default in the performance of any obligation of Landlord 
under the Lease which a mortgagee or lender or a purchaser or prospective 
purchaser of the Building or any interest therein or any other party may 
reasonably request.


33.     General Provisions:

(a)     The various rights and remedies contained in this Lease and reserved
to 
each of the parties shall not be exclusive of any other right or remedy of
such 
party, but shall be construed as cumulative and shall be in addition to every 
other remedy now or hereafter existing at law, in equity, or by statute.  No 
delay or omission of the right to exercise any power by either party shall 
impair any such right or power, or shall be construed as a waiver of any
default 
or as acquiescence in any default.  No covenant, term or condition shall be 
deemed waived by Landlord except by a writing.  One or more waivers of any 
covenant, term or condition of this Lease by either party shall not be
construed 
by the other party as a waiver of a subsequent breach of the same covenants, 
terms or conditions or any other covenant, term or condition.  The consent or 
approval of either party to or any act by the other party of a nature
requiring 
consent or approval shall not be deemed to waive or render unnecessary consent 
to or approval of any subsequent similar act.

No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall 
be due from Tenant to Landlord shall be treated otherwise than as a payment on 
account.  The acceptance by Landlord of a check for a lesser amount with an 
endorsement or statement thereon, or upon any letter accompanying such check, 
that such lesser amount is payment in full, shall be given no effect, and 
Landlord may accept such check without prejudice to any other rights or
remedies 
which Landlord may have against Tenant.

(b)     Payments to Landlord under this Lease are rental for the use of the 
Premises, and nothing herein contained shall be deemed or construed to make 
Landlord a partner or associate of Tenant in the conduct of any business, nor
as 
rendering Landlord liable for any debts, liabilities or obligations incurred
by 
Tenant in the conduct of any business, it being expressly agreed that the 
relationship between the parties is, and shall at all times remain, that of 
landlord and tenant.

(c)     All amounts payable by Tenant to Landlord under any provision of this 
Lease other than Basic Annual Rent shall be deemed to be additional rental for 
the use of the Premises, and Landlord shall have the same remedies for the 
nonpayment of such amounts as for the nonpayment of Basic Annual Rent.

(d)     Where the words "Landlord" and "Tenant" are used in this Lease, they
shall 
include Landlord and Tenant and shall apply to persons, both men and women, 
associations. partnerships and corporations, and in reading this Lease, the 
necessary grammatical changes required to make the provisions hereof mean and 
apply to them shall be made in the same manner as if written into the Lease.

solely upon the statements contained in this Lease and fully understanding
that 
no agents or representatives of Landlord have authority to in any manner
change, 
add to or detract from the terms of this Lease.  Landlord shall not be deemed
to 
have made any other representations or agreements, express or implied.

(f)     The invalidity of one or more of the provisions of this Lease shall
not 
affect the remaining portions of this Lease; and, if any one or more of the 
provisions of this Lease should be declared invalid by final order, decree or 
judgment of a court of competent jurisdiction, this Lease shall be construed
as 
if such invalid provisions had not bee included in this Lease.

(g)     If Tenant shall be two or more persons or entities, each such person
shall 
be jointly and severally liable for the payment of all sums due to Landlord
from 
Tenant under this Lease and the performance of all of Tenant's covenants, 
agreements, or obligations under this Lease.

(h)     If either Landlord or Tenant shall be delayed or prevented from the 
performance of any act required hereunder by reason of acts of God, strikes, 
lockouts, labor troubles, inability to procure materials, restrictive 
governmental laws or regulations or other cause without fault beyond their 
control (financial inability and Tenant's obligation to pay Rent excepted), 
performance of such acts shall be excused for the period of such delay and the 
period for the performance of any act shall be extended for a period
equivalent 
to the period of such delay.

(i)     Where the word "Term" is used in this Lease, it shall also include the 
word "Extended Term" as the context shall so require.

(j)     Whenever the approval or consent of Landlord is required hereunder,
such 
approval or consent may be withheld or conditioned in Landlord's sole
discretion 
unless expressly otherwise set forth.

may 
have against Tenant by reason of any one or more payments or acts in
compliance

of 
non-performance, protests, notices of dishonor, and notices of acceptances of

NOTICE OF NONCOMPLIANCE

NOTICE OF AUDIT FINDINGS

Dear Mr. Borgwing:

During May, 1995, the Massachusetts Department of Environmental Protection 
(the Department) conducted an audit of certain activities related to the above 
referenced disposal site pursuant to the Massachusetts Contingency Plan (MCP), 
310 CMR 40.1100. That audit is now complete.

The purpose of this Notice is to inform you that, as a result of the 
audit, Department personnel have determined that you are in noncompliance with 
one or more laws, regulations, orders, licenses, permits, or approvals
enforced 
by the Department, The specific aspects of the noncompliance and the measures 
the Department wants you to take to come into compliance are described in this 
Notice of Noncompliance.

The audit included a windshield survey conducted on May 8, 1995, a review 
of the documents listed below, and a review of other information in the 
Department's files:

1)      LSP Evaluation opinion report, prepared for WASA Management by 
Environmental Science Services (ESS), and dated June 17, 1994; and

2)      "Phase I - Limited Subsurface Investigation of 580 Winter Street, 
Waltham, Massachusetts", prepared for Prudential Realty Group by Certified 
Engineering & Testing Company and dated May 9, 1989.

SITE SUMMARY

On August 14, 1987, a 10,000 gallon petroleum underground storage tank 
(UST) was removed from the subsurface at 580 Winter Street, Waltham, 
Massachusetts.  Soil contaminated with number 4 fuel oil was discovered in
this 
tank excavation.  The Department was notified of this release on August l7, 
1987.

An Environmental Site Investigation for the property was completed by 
Goldberg-Zoino & Associates, Inc. (GZA), in January 1989.  Six soil borings
were 
drilled and four groundwater monitoring wells were installed.  Fuel oil and 
chlorinated volatile organic chemicals (VOCs) were detected in soil and 
groundwater samples from the site.  VOCs were not detected in soil at the site 
at levels exceeding the MCP RCS-l Reportable Concentrations.  Trichloroethene 
was measured in a groundwater sample from well GZA-2 at a concentration of 21 
ug/l, which exceeds the RCGW-1 concentration of 5 ug/l.

A Phase I-Limited Site Investigation was conducted by Certified 
Engineering & Testing Company during the spring of 1989, On March 16 and 20, 
1989, borings were drilled at the property, Split spoon screening was
conducted 
at five foot intervals in these borings, Two groundwater monitoring wells were 
installed.  Three shallow soil samples were also

collected at this tine.  These shallow soil samples were collected with a 
shovel from a depth of two feet. fuel oil and chlorinated VOCs were again 
detected in soil and groundwater samples from the site.  VOCs were not
detected 
in soil at levels exceeding the MCP RCS-l Reportable Concentrations, 
Trichloroethene was measured in a groundwater sample from well GZA-2 at a 
concentration of 9.6 ug/l, which exceeds the RCGW-1 concentration of 5 ug/l.  
Total Petroleum Hydrocarbon (TPH) was measured in a groundwater sample from
well 
MW-103 at a concentration of 6 MG/1, which exceeds the RCGW-1 concentration of
l 
mg/l.

A Preliminary Environmental Assessment was conducted by Environmental 
science services (ESS).  ESS collected groundwater samples from existing 
monitoring wells in November 1992 and December 1993.  Trichloroethene wag 
measured in a groundwater sample from well GZA-3A at a concentration of 7 ug/1 
in November 1992 (RCGW-1 = 5 ug/1).  Trichloroethene was not detected in a
water 
sample collected from this well in December 1993 (detection limit 5 ug/1).

LSP EVALUATION OPINION

The LSP Evaluation Opinion states that, "the subject site presents no 
significant risk to its occupants, the surrounding properties, or the City of 
Cambridge water supply.  Since no contaminants listed in the MCP were
currently detected, and previously collected groundwater samples were below the
applicable RCGW-2 standards, it is the opinion of the undersigned that the
location is not a disposal site where a release of oil and/or hazardous
materials has occurred which is subject to the notification requirements of
310 CMR 40.0300, and that no further response actions are required."

SITE VISIT

On May 8, 1995, a representative of the Department completed a windshield 
survey of the subject site.  The location of the property with respect to the 
Cambridge Reservoir was noted.  Winter Street, and a narrow wooded area 
bordering the street, lie between the site and the Reservoir.  The site is 
located on a hill overlooking Winter Street.  Surface topography slopes
strongly 
toward winter Street in this area, Surface water runoff is collected by storm 
drains which empty into a retention pond in the Winter Street median strip.  A 
small stream, which flows in a southerly direction, away from the Cambridge 
Reservoir, is located east of the site, opposite a Guest Quarters suite Hotel. 

No sheens were observed on either the retention pond or the stream.

NOTICE OF NONCOMPLIANCE

The following is a description of (1) each activity identified during the 
audit which is in noncompliance, (2) the requirements violated, (3) the action 
the Department now wants you to take, and (4) the deadline for taking such 
action, An administrative penalty may be assessed for every day from now on
that 
you are in noncompliance.

Notwithstanding this Notice of Noncompliance, the Department reserves the 
right to exercise the full extent of its legal authority in order to obtain
full 
compliance with all applicable requirements, including, but not limited to, 
criminal prosecution, civil action including court-imposed civil penalties, or 
administrative penalties assessed by the Department.

ENTITY IN NONCOMPLIANCE

WASA Management
30 Federal Street
Boston, MA 02110
DEP RTN #3-2117

LOCATION WHERE NONCOMPLIANCE OCCURRED OR WAS OBSERVED

Waltham, 580 Winter Street

DATE(S) WHEN NONCOMPLIANCE OCCURRED OR WAS OBSERVED

June 22, 1994, the date the Department received a Licensed Site 
Professional Evaluation Opinion/Report dated June 17, 1994 .

DESCRIPTION OF ACTIVITY OF NONCOMPLIANCE

The LSP Evaluation opinion did not identify the applicable groundwater 
category for the site,

DESCRIPTION OF REQUIREMENT(S) NOT COMPLIED WITH

The LSP Evaluation Opinion compared contaminant concentrations in 
groundwater at the site to the MCP RCGW-2 Reportable Concentrations.  However, 
based on a measurement made from the Maynard, Massachusetts, USGS Quadrangle 
(scale = 1:25,000), the site is located approximately 325 feet from the shore
of the Cambridge Reservoir, a Class A surface water body used as a public
drinking water supply.  Pursuant to section 40.0362(l)(a)(4) of the MCP, the
reporting category for groundwater at the site is RCGW-1 because the site is
located within the Zone A of the Cambridge Reservoir,

Groundwater monitoring well MW-103 contained TPH at a concentration of 6 
mg/l when last sampled in March 1989.  This level exceeds the MCP RCGW-1 TPH 
Reportable Concentration of 1.0 mg/l.  Groundwater monitoring well MW-101 
contained trichloroethene at a concentration of 55 ug/1 when last sampled in 
March 1989.  This level exceeds the MCP RCGW-1 trichloroethene Reportable 
Concentration of 5.0 ug/l.

Based on the RCGW-1 groundwater category and levels of trichloroethene and 
fuel oil in groundwater, the site is subject to the notification requirements 
pursuant to 310 CMR 40.0300.

DESCRIPTION OF DEADLINE(S) OF ACTION TO BE TAKEN

Submit to the Department, within 60 days of the date of this Notice, in 
accordance with 310 CMR 40.0610(5), a revised LSP Evaluation opinion which 
indicates in Section B. that a release subject to the notification
requirements of 310 CMR 40,0300 occurred or may have occurred at the subject
site and that further response actions are necessary. This LSP Evaluation
Opinion must be accompanied by either a Tier Classification Submittal
Transmittal Form (BWSC-107) completed in accordance with 310 CMR 40,0500 with a
Tier I Permit Application if necessary, or a Response Action Outcome 
Statement (BWSC-104) completed in accordance with 310 CMR 40,1000.

The revised LSP Evaluation opinion must also be accompanied by a letter 
requesting that the Department rescind the original LSP Evaluation Opinion
dated June 17, 1994 (received by the Department on June 22, 1994) and replace it
it with the revised LSP Evaluation opinion.

If the requested documents are not received by the Department within 60 
days of the date of this Notice, pursuant to 310 CMR 40.0610(6), the site will 
default to a Tier 1B Classification and Tier 1B Annual Compliance Fees will be 
assessed.

A copy of this Notice has been sent to your LSP.  You may consult with 
your LSP when preparing a response to this Notice, Note, however, that you,
not your LSP, are obligated to respond to this Notice and remedy the
violation.
  
Note that any submittal to the Department made in response to this Notice must 
include the certification statement specified in 310 CMR 40,0009, signed by an 
authorized individual.

CONCLUSION

You are advised to respond to the Notice of Noncompliance within the 
timeframes outlined above to avoid additional enforcement action by the 
Department.

DEP Site No. 3-2117

1.0 INTRODUCTION

This document presents information, an evaluation, and conclusions in 
support of a Response Action Outcome (RAO) Statement for the property located
at 
580 Winter Street, Waltham, Massachusetts (the Site).  This document and the 
included RAO forms address the presence of fuel oil and trichloroethene
detected 
in groundwater on a portion of the Site.

A LSP Evaluation Opinion by Environmental Science Services (ESS) dated 
June 17, 1994 concluded that the site presents no significant risk to its 
occupants, the surrounding properties, or the City of Cambridge water supply 
based on the existing levels of groundwater contamination at the Site and a 
reporting category for groundwater at the site of RCGW-2.  Subsequent review
of 
this document by DEP in a memorandum dated May 16, 1995 stated that the 
reporting category for groundwater at the Site should be RCGW-1 based on its 
proximity to the Cambridge Reservoir.  This review noted that the residual 
concentrations of fuel oil and trichloroethene exceed the RCGW-1 Standards.  
Therefore, the LSP Evaluation Opinion was not an appropriate end point for the 
evaluation of this Site, and a risk characterization is required.

This document presents an opinion that, despite the RCGW-1 designation 
affirmed in DEP's communication, the groundwater should not be classified as
GW-1 for the purposes of risk characterization.  This opinion is supported by
our interpretation of the particular hydrogeologic conditions at the Site.

This document describes:

- -       the location and nature of the releases;
- -       the assessment of residual-conditions; and
- -       a risk characterization based upon the results of the assessment work.

A Class B-2 RAO has been designated for the Site based on the following 
conclusions:

1)      A level of "no significant risk" exists.

2)      No remediation was undertaken at the Site.

3)      Residual concentrations of fuel oil and several solvents exceed 
     background levels.

2.0 DESCRIPTION OF THE SITE

The Site is located in the industrial park near the 'intersection of 
Winter Street and Route 128 in Waltham, Massachusetts.  The building is on the 
southwest comer of the intersection of Winter Street and First Avenue.  The 
larger parking lot abuts West Street and is southwest of the building lot. 
The 
building is surrounded on the east, west, and south by other commercial and 
industrial proper-ties.  Across Winter Street to the north is the Cambridge 
Reservoir, a primary storage reservoir serving the public water supply of the 
City of Cambridge.  A locus map and site plan map are attached as Figures I
and 2, respectively.

3.0 HISTORY OF RELEASE

The initial site investigation was conducted by Goldberg-Zoino & 
Associates, Inc. (GZA) with their report dated January 1989.  A follow up
effort 
was conducted by Certified Engineering and Testing (CET) with their report
dated 
May 1989.  The sampling by these firms in December 1988 and March 1989
detected 
low levels of chlorinated solvents, such as trichloroethene, as well as total 
petroleum hydrocarbons (TPH).  The Site was subsequently reported to the 
Massachusetts Department of Environmental Protection (DEP).  No specific
source 
was identified for the solvents, whereas the TPH contamination was attributed
to 
small overfills of a former underground fuel oil tank, found to be intact on 
removal.

A Preliminary Environmental Assessment and Limited Subsurface 
Investigation was completed by ESS in April 1993.  This included analysis of 
groundwater samples collected in December 1992 from the four existing
accessible 
monitoring wells on the property.  ESS concluded that there was no visual 
evidence of a release or a significant threat of a release of oil or hazardous 
material to the property.  However, analysis of the groundwater samples
detected 
low levels of volatile organic compounds (VOCs).  A summary of all available 
analytical results for groundwater is attached as Table 1.

4.0 GROUNDWATER CLASSIFICATION

The subject Site was located on the 7.5- by 7.5-minute Concord quadrangle 
of the Massachusetts Geographical Information System (MASSGIS) maps at the DEP 
Northeast Region office in Woburn, Massachusetts.  According to that map,
there 
are no wells or pumping stations for public water supply within a radius of at 
least 1 mile from the subject Site.  The building on the property is 
approximately 325 feet from the southern edge of the Cambridge Reservoir, and 
1,500 feet from the ghettoize which regulates the reservoir's outlet into Hobs 
Brook, but there is no protected zone designation associated with the
Cambridge 
Reservoir noted on the

MASSGIS maps in this area.  According to the maps entitled "Hydrology and 
Water Resources of the Charles River Basin, Massachusetts," published by the 
USGS, the subject property is not underlain by any aquifer that is favorable
for 
development of water supply wells.

In accordance with 3 1 0 CMR 40.0932, and based on the proximity of the 
Site to the Cambridge Reservoir, the Site is in the Zone A of a Class A
Surface 
Water Body.  As stated in DEP's memorandum of May 16, 1995, this condition 
requires classification of Site groundwater as RCGW-1 for reporting purposes.  
However, for the purposes of Risk Characterization, ESS believes that the 
appropriate classification of the groundwater at the Site is GW-2 and GW-3, 
based on its particular hydrogeologic setting.  The following discussion on
this 
topic is based on three sources of information: the USGS Topographic Map for
the 
Maynard Quadrangle, the GZA environmental site assessment of the Site dated 
January 5, 1989, and the CET environmental site assessment for the Site dated 
May 9, 1989.

Although this Site is within 400 feet of a Class A Surface Water Body, the 
water body in question is a dammed reservoir, and, based on the topography as 
depicted in the USGS Maynard Quadrangle, the Site is located on the regionally 
downgradient side of the dam.  Surface water bodies typically gain part of
their 
recharge from inflowing groundwater.  However, along a certain portion (along 
the regionally downgradient side) of the perimeter of water bodies,
groundwater 
is often recharged from surface water, flowing away from the water body.  This 
is more consistently and predictably the case for dammed water bodies, where 
surface water is artificially maintained above its natural elevation.

In this case, two observations support the conclusion that the Site is 
located in such a zone, and that groundwater beneath the Site flows to the
more 
distant Hobbs Brook 'rather than the Cambridge Reservoir.  The first
observation 
is that relative groundwater elevations at the Site, as measured on two 
occasions (December 1989 and May 1989), show groundwater flow in a southerly 
direction, away from the reservoir.  The second observation is that estimated 
absolute groundwater elevations at the Site are below the elevation of the
water 
surface of the reservoir, as depicted on the USGS Topographic map.  ESS 
estimated the absolute groundwater elevations (above MSL) at the Site based on 
the topographic contours provided on the USGS Quadrangle map.  The average 
elevation of the four monitoring wells GZA-1, GZA-2, GZA-3 and MW-103 was 
assumed to be 177.1 feet.  The elevation of each individual well was then 
estimated based on the difference from average as determined from the relative 
elevation survey provided by CET.  Groundwater elevations were then computed
for 
the four wells based on measured depth to water on two separate occasions.  
These elevations can be directly compared with the elevation of the water 
surface of the reservoir.  These data are summarized in Table 2.

Whereas the elevation of the reservoir surface is 172.2 feet above MSL, 
the groundwater elevations at the Site are between 161.78 and 163.51 ft, with 
the exception of one measurement in well MW-103 of 169.6. Groundwater
elevations 
at the Site are therefore generally about 10

feet below the elevation of the reservoir surface as reported on the USGS 
Quadrangle map.  In the case of MW-103, in which groundwater is 2.6 feet below 
the elevation of the reservoir, two points need to be considered.  First, this 
well is the closest to the reservoir of all the wells at the Site, and second, 
this well is installed directly above the shallow refusal depth of 10 feet. 
It 
is possible that the groundwater elevation in this well reflects a local 
condition.  In any case, the data indicates a hydraulic gradient away from the 
reservoir.

For groundwater elevations across the Site to rise above the level of the 
reservoir, the reservoir level would have to drop as much as 10 feet.  The 
drought conditions that would cause this condition would of course also cause 
groundwater levels at the Site to drop as well, making it unlikely that the
flow 
in this region would reverse for any significant length of time.  Even so,
based 
on reasonable and conservative estimates of hydraulic conductivity and
porosity, 
the hypothetical travel times for transport of pollutants from the Site to the 
reservoir can be computed.  Assuming a hydraulic conductivity of 100 feet per 
day and a porosity of 0.3, the reservoir would have to drop 15 feet without
the 
groundwater dropping at all and stay this way for 60 days for groundwater at
the 
Site to reach the reservoir.  This scenario is not within the realm of 
possibility.  It is more likely that groundwater levels at the Site would drop 
along with the reservoir level, increasing the travel time to the reservoir to 
the order of years, long enough that seasonal increases in reservoir level
would 
return the gradient to its average direction long before any contaminant 
migrating in groundwater could reach the reservoir.

</TABLE>

These observations indicate that either: 1) a groundwater divide exists 
between the reservoir and the Site, or 2) that the southern shore of the 
reservoir is located in the zone where surface water recharges groundwater,
and 
groundwater flow between the reservoir and the Site is generally towards the 
Site.  In either case, groundwater quality at the Site should have no 
significant impact on water quality in the reservoir, and therefore should not 
be classified as GW-1.  This opinion is based on logic parallel to that 
appearing in 310 CMR 40.0932(5), which allows for exceptions to the GW-1 
classification to be made based on local hydrogeologic conditions in the case
of groundwater resources.  Specifically, the exceptions are made relative to 
groundwater resources when a lack of hydrogeologic connection between the site 
and the resource area is shown or the regulated boundaries of a resource area 
are shown to be inaccurate based on site-specific data.  Although these 
provisions are not explicitly granted in the case of surface water resources, 
ESS believes that both of these conditions apply to this Site, and concludes 
that the applicable groundwater standard for this Site should be GW-2 and GW-3.

5.0     RISK CHARACTERIZATION

A Method 1 risk characterization has been performed in accordance with 310 
CMR 40.0970 and 40.0980 of the Massachusetts Contingency Plan (MCP).  This 
characterization is made based on the residual concentration of several
solvents and TPH existing in areas classified as GW-2 and GW-3, as described 
above.

5.1     Exposure Point Concentrations

Exposure point concentrations (EPCs) have been calculated for the 
various solvents detected at the Site as the maximum concentration detected in 
any well over the period of investigation. These concentrations, along with
the relevant GW-2 and GW-3 standards, are provided in Table 3.

Potential Receptors and Migratory Pathways

As part of this risk characterization, ESS has considered what potential 
receptors and migratory pathways exist at the Site.  The dissolved solvent and 
TPH concentrations are not large enough to pose a threat to air quality.  The 
Site is not functionally located in a GW-l area, and the nearest known water 
supply wells are located over I mile from the Site.  The Cambridge Reservoir, 
located 325 feet north of the Site, is upgradient.  A wetland south of the
Site, 
the likely discharge point for groundwater flowing under the Site, is located 
approximately 2,000 feet downgradient.  Hobbs Brook, which probably receives 
recharge from water flowing through the wetland, is the eventual receptor of 
groundwater flowing through the Site.  However, during the considerable travel 
time between the site and the brook, the low levels of organic compounds
present 
will be most likely be greatly diminished due to sorption, biodegradation, and 
volatilization.

5.3     Risk Characterization

Based on a comparison of the maximum concentrations of all compounds 
detected at the Site to below the applicable Method 1 GW-2/3 standards, ESS 
concludes that no significant risk is posed by the presence of residual 
contamination at this Site.

6.0 RAO OPINION

After reviewing laboratory data from assessments conducted at the Site, 
ESS has reached the following conclusions:

     dissolved concentrations of various solvents and TPH are below GW-
     2/3 standards;
the contaminants detected in groundwater at the Site will not pose a 
 significant risk of harm to health, public welfare or the environment;
and the Site meets the requirements for a Class B-1 RAO.

TABLE 1 RESULTS OF GROUNDWATER ANALYSIS

Table of results of Groundwater Analysis Samples of Various Well Test Sites
taken by various enviornmental engineers from 1988 through 1993.  Tests were
done in 1988, 1989, 1992 and 1993.  Not all wells were tested each year.  The
test well showing the level of total petroleum hydrocarbon level and the test
well showing the trichloroethene level which levels the Massachusetts
Department of Environmental Protection indicated exceeded the public drinking
water standard (GW-1) have not been tested since 1989.  The summary of all of
these test results at their highest levels of detection appears in Section 5.1
(of this Exhibit 10.6) as "Table 3 Maximum Concentrations of TPH and Solvents 
Detected in Groundwater at the Site and Relevant GW-2/GW-3 Standards."
