or before the first (1st) day of each and every calendar month of the Term.

(b)  Rent To Be Net.

It is the  purpose  and intent of the  Lessor and the Lessee  that the Base Rent
shall be net to the Lessor so that this Lease  shall  yield,  net to the Lessor,
the Base Rent  specified in Section  3(a) hereof in each Lease Year,  except for
the  structural  repairs  which  shall be the  responsibility  of the  Lessor as
provided for in Section 9 of this Lease.

(c)   Common Area Maintenance, Taxes and Insurance Expenses.

The Lessee  agrees to pay  50.00% of all common  area  maintenance  (CAM),  real

five of the lease Term, the estimated charges for Additional Rent shall increase
to $2,048 per month. At the end of each calendar year or at the end of the lease
Term,  the Lessor shall provide a  reconciliation  of expenses  incurred for the
period.  The Lessor shall either bill the Lessee for  additional CAM charges due
or provide the Lessee a credit for the Base Rent due for the next rental period.
Upon the end of the lease Term, the Lessor will provide a reconciliation  of the
Additional Rent incurred by Lessee. Upon request, Lessee shall have the right to
review all invoices pertaining to Additional Rent.

     (3)    Insurance.

     Lessee shall pay to Lessor 50.00% of the insurance premiums for coverage on
all common areas of the Building and Land at 4 Bellows Road. Lessor shall obtain
such  insurance  for the Leased  Premises,  the  Building,  and any  appurtenant
parking  areas as it deems  appropriate,  and the Lessee  shall have no right to
proceeds or claims thereunder.

     To the  extent  that the  Lessee's  use of the Leased  Premises  causes any
additional  premium  for the  Lessor's  insurance,  the  Lessee  shall  pay such
additional  premium as Additional Rent within ten (10) days of Lessee's  written
request  therefor.  The Lessee shall obtain its own insurance to cover losses to

responsible for any losses not covered by its insurance according to Section 13.

(d)  Additional Rent.

All Additional  Rent payments for  Additional  rent shall be due within ten (10)
days of a Notice by Lessor to Lessee that such payments are due. Lessor reserves
the same rights and remedies against the Lessee for default in making Additional
Rent  payments  as the Lessor  shall have for default in the payment of the Base
Rent,  including but not limited to, the right to seek and recover such payments
as rent under any applicable provisions of the United States Bankruptcy Code.

(e)  Late Charges.

If Base Rent or Additional  Rent for any month has not been paid by the close of
business of the tenth (10th)  business day of said month,  the Lessee  agrees to
pay a late charge of five (5%) percent of the total amount due to the Lessor. An
assessed  late  charge  shall be  deemed  Additional  Rent and  shall be due and
payable ten (10) days after the  notification of such  assessment.  In the event
that the Base Rent or Additional  Rent has not been received  within thirty (30)
days  following the payment due date, an additional  interest  charge of one and
one half  (1.5%)  percent per month shall be payable to the Lessor from the date
the payment  was due and this charge shall  constitute  Additional  Rent payable
hereunder.

(f)    Option Term Rent.

The Base  Monthly  Rent  during the Option  Term shall be equal to the then fair
market rent for comparable  space upon comparable  terms in the Westborough area
but said rent shall not be less than the Base Rent of the previous Term.

4. UTILITIES.

(a) lessee shall be responsible  for paying 100% of the cost of utilities to the

(b) The Lessor  shall not be liable to the Lessee in damages or otherwise if the
furnishing  of any one or more of the  utilities  is  interrupted,  impaired  or
terminated  because of the  failures,  repairs,  acts of God,  installations  or
improvements  nor shall any  interruption,  impairment  or  termination  release
Lessee from the  performance  of any of its  obligations  hereunder.  The Lessor
reserves the right to stop  service on any or all  utilities  when  necessary by
reason of accident or emergency,  or mechanical breakdown, or requirement of law
or any cause beyond  Lessor's  reasonable  control or for repairs,  alterations,
replacements or improvements which, in the judgement of the Lessor are desirable
and necessary,  until the reason for such stoppage  shall have been  eliminated.
Lessor shall use reasonable  efforts at all times to keep all utilities in sound
working order and good repair.

5. OCCUPANCY OF THE LEASED PREMISES.

The  taking of  occupancy  of the whole or part of the  Leased  Premises  by the
Lessee, shall be conclusive evidence, as against the Lessee, that Lessee accepts
possession  of the same and that the Leased  Premises and the  Building  were in

23. EMINENT DOMAIN.

(a) If the entire  building on the Leased  Premises shall be taken for public or
quasi-public purposes, then this Lease shall terminate as of the date the Lessee
shall be  required  by law to vacate  the  premises  and  surrender  them to the
authority making the taking.

(b) If such portion of the building on the Leased  Premises shall be taken as to
render  the Leased  Premises  unsuitable  for the  continuance  of the  Lessee's
business  in  substantially  the same  manner  as the same was  being  conducted
immediately  prior to such  taking,  then the  Lessee  shall  have the  right to
terminate this Lease at Lessee's sole discretion by giving written notice to the
Lessor  within thirty (30) days after receipt of Notice of Entry for purposes of
effectuating  the  taking.  If the cost of  repairing  or  restoring  the Leased
Premises after a partial taking is more than twenty (20%) percent of their value
as determined by the City of Westborough's  tax assessment  immediately prior to
such taking, the Lessor may at its option terminate this Lease by written notice
to the Lessee  within  thirty (30) days after the date of the taking;  provided,
that if this Lease shall not be so terminated, the Lessor shall restore, only to
the extent of the receipt of the eminent domain proceeds,  the building with all
reasonable dispatch to a complete architectural unit as close as possible to the
condition the building was in immediately prior to said taking. Any provision of
the  subparagraph (b) to the contrary  notwithstanding,  the Lessor shall not be
required  to  restore  if  the  Lessor's   mortgagees  shall  refuse  to  permit
application  of the  Lessor's  condemnation  proceeds  towards the costs of such
restoration.

(c) If the Leased Premises, or any part thereof,  shall be rendered untenantable
and  this  Lease  is not  terminated,  the Rent  herein  reserved  or a just and
proportionate part thereof, shall be suspended or abated according to the nature
and extent of the taking from the date of such taking until the Leased  Premises
shall be restored, and if after such restoration the Leased Premises are smaller
than they were  prior to the  taking or the  utility  thereof  to the  Lessee is
otherwise diminished, the annual rent shall be equitably reduced.

(d) Upon any such taking,  the proceeds  thereof shall be payable to the Lessor,
and the Lessee  shall have  absolutely  no right or interest  in any award.  The
Lessee  hereby  irrevocably  appoints  the  Lessor as its  attorney  in fact for
purposes  of  collecting  any  such  condemnation  award  and  dealing  with all
governmental authorities with respect thereto. This power of attorney is coupled
with an interest and is irrevocable.

(e) If the Lessor shall be obligated to repair or restore as  aforesaid,  and if
the Leased  Premises are not  repaired or restored  within four (4) months after
the date of such  taking,  then the Lessee may, in addition to all other  rights
and remedies it may have, terminate this Lease.

24. DISPUTES.

The parties  hereto  agree that if at any time a dispute  should arise as to the
propriety  or  necessity  of the Lessee  making any  payment or  performing  any
obligations  required  hereunder,  the Lessee may pay or perform  the same under
protest and such payment or performance under protest shall not be considered to
be voluntary on the part of the Lessee.

25. ATTORNEY'S FEES.

In the event that either party to this Lease brings an action  against the other
to enforce any  covenant of this Lease,  including  actions for Base Rent and/or
Additional  Rent or other  payments  due and  actions  in summary  process,  the
prevailing  party,  as  determined  by the  entry  of a  judgment  by a court of
competent  jurisdiction,  shall be  indemnified  by the other party  against all
legal costs and charges, including reasonable attorney's fees.

26. ASSENTS.

No assent,  expressed or implied,  by one party to any breach of any covenant or
condition herein contained on the part of the other to be performed or observed,
and no waiver, expressed or implied, of or failure by one party to insist on the
other's prompt performance or observance of any such covenant or condition shall
be deemed to be a waiver of or assent to any  succeeding  breach of the same, or
any other covenant or condition,  and, except as provided herein,  any party may
assert its rights and remedies  hereunder without any prior or additional notice
to the other that it proposes to do so. The payment by the Lessee and acceptance
by the Lessor of Base Rent and/or  Additional Rent or silence by either party as
to any breach  shall not be  construed  as waiving  any of such  party's  rights
hereunder  unless  such  waiver  is in  writing.  No  payment  by the  Lessee or
acceptance  by the Lessor of a lesser  amount  than shall be due the Lessor from
the  Lessee  shall be deemed to be  anything  but  payment on  account,  and the
acceptance by the Lessor of a check for a lesser amount with an  endorsement  or
statement  thereon or upon a letter  accompanying said check shall not be deemed
an accord  and  satisfaction  and the  Lessor  may  accept  said  check  without
prejudice  to recover the balance  due or pursue any other  remedy  which any be
available to it.

27. CUMULATIVE RIGHTS.

Any and all rights and remedies which either party may have  hereunder  shall be
cumulative and the exercise of any one of such rights shall not bar the exercise
of any other right or remedy which said party may have.

exercise of the Option Term or  negotiate  a new Lease  Agreement  not less than

Lessee has affirmed its intention of remaining at the Leased  Premises,  a Lease
agreement  shall be mutually  agreed to by both  parties no later than three (3)
months prior to the end of the current lease Term.

The Lessee, at the expiration of the Term hereof, or at any prior termination as

God, acts of war and the enemy and acts of paramount authority only excepted.

prior to the expiration of the Term hereof, or prior termination thereof, remove

Leased  Premises,  provided that if such removal causes any damage to the Leased
Premises, the Lessee shall promptly repair the same.

the last year of the lease Term at the rate of one and one half (1.5)  times the
rent  payable  during any hold over period after the Term or Option Term of this
Lease has  terminated,  subject to all of the other terms and conditions of this
Lease  insofar as the same are  applicable to a  month-to-month  tenancy and the
Lessee  as  a  holdover  tenant  shall  be  considered  solely  as a  tenant  at

thereafter and reserves all rights and remedies with respect to the  termination
of this Lease Agreement.

permitted to do under the terms of this Lease Agreement.

other  communication be given or served by either party to this Lease to or upon
the other,  such notice  shall be deemed to have been duly  delivered,  given or

requested,  postage prepaid, addressed to the party to whom it is to be given or
served in the case of the Lessor at the most recent place to which rental checks

or  unenforceable  under  applicable  law,  such  provision  shall,  insofar  as

otherwise,  this Lease shall be  construed as if such  provision  had never been
made a part hereof.
