          Early Space is added to the Demised Premises pursuant to Section 2,
          Additional Rent during Period 1 shall be increased accordingly, and
          Base Rent shall be due with respect to such Early Space unless it is
          part of the New Third Floor Premises, as further set forth in
          Subsection (e) below.

     (b)  Period 1A: July 1, 1998 through December 31, 1998 - Twenty-Three
          Thousand Four Hundred Sixty-Two Dollars and Twenty-Three Cents
          ($23,462.23) per full calendar month. This amount is based on an
          Annual Base Rent rate of Four Dollars and Seventy-Five Cents ($4.75)
          per square foot for Fifty-Nine Thousand Two Hundred Seventy Three
          square feet (59,273 SF). No Base Rent shall be payable with respect to

          space within the First Additional Premises on the third floor of
          Building No.3 (the "New Third Floor Premises"), including any portion
          thereof which is added to the Demised Premises as Early Space, for a
          period of six (6) months. Notwithstanding the foregoing, the above
          monthly payments of Base Rent shall be reduced pursuant to Subsection
          (f) below. No Additional Rent shall be payable with respect to the New
          Third Floor Premises until the Landlord has completed the Landlord
          Work described in Paragraph 8.1(a) below; except that Tenant shall pay
          Additional Rent for any New Third Floor Premises which is delivered to
          Tenant at its request as Early Space with Landlord Work completed.

     (c)  Period 2: January 1, 1999 through the Expiration Date:

          (i) January 1, 1999 through March 31, 1999 - Thirty-One Thousand Five
          Hundred Ninety-Six and Twenty-One Cents ($31,596.21) per full calendar
          month. This amount is based on an Annual Base Rent rate of Four
          Dollars and Seventy-Five Cents ($4.75) per square foot for Seventy-
          Nine Thousand Eight Hundred and Twenty-Two square feet (79,822 SF),

                                      6
 
          (ii) April 1, 1999 through March 31, 2002- Thirty Nine Thousand Nine
          Hundred Eleven Dollars ($39,911) per full calendar month. This amount
          is based on an Annual Base Rent rate of Six Dollars ($6.00) per square
          foot for Seventy-Nine Thousand Eight Hundred and Twenty-Two square
          feet (79,822 SF); and

          (iii) April 1, 2002 through the Expiration Date - Forty-Three Thousand
          Two Hundred Thirty-Six Dollars and Ninety-Two Cents ($43,236.92) per

          of Six Dollars and Fifty Cents ($6.50) per square foot for Seventy
          Nine Thousand Eight Hundred Twenty Two square feet (79,822 SF).

     (d)  The monthly Base Rent for any partial month at the beginning or end of
          the Term shall be prorated at the rate of 1/30 of the then current
          installment of Base Rent for each day in such partial month.

     (e)  The monthly Base Rent for Period 1A identified above shall not
          commence until Landlord has delivered the space in the condition
          identified in Article 8.1. Further, Tenant shall be entitled to six
          (6) months free Base Rent with respect to all of the New Third Floor
          Space, beginning on the date any such space is added to the Demised
          Premises, whether as Early Space or otherwise. Thus, for example, if
          600 square feet of New Third Floor Space is added to the Demised
          Premises on June 1, 1998 and 1,200 square feet is added on July 1,
          1998 and the balance is added on August 1, 1998, the Base Rent for the
          first such space shall begin on December 1, 1998, the second such
          space on January 1, 1999 and the third such space on February 1, 1999.

     (f)  The monthly Base Rent for each of the months of May, June, July,
          August, September and October, 1998 shall be reduced by a credit in
          the amount of $2,417.72 each month (for a total reduction of
          $14,506.33) in order to reimburse Tenant for its previous payment of
          $31,772.60 as Base Rent for the month of April, 1998, or an excess
          payment of $14,506.33. Accordingly, for the months of May and June
          1998 the amount to be paid monthly for Base Rent shall be $14,808.55
          and for the months of July 1998 through October, 1998, the amount to
          be paid monthly for Base Rent shall be $21,044.51.
                                                 ---------- 


     2.   Extended Term: The Annual Base Rent for the Extended Term shall be
Ninety-Five Percent (95%) of the Fair Market Rental Value ("FMRV") at the
commencement of such Extended Term. The FMRV shall be determined as follows:

     (a)  Upon receipt by Landlord of Tenant's written notice exercising its
          option to extend the Lease as provided above in Article 3.2, Landlord
          shall within ten (10) days provide Tenant with a proposed rent
          schedule for Annual Base Rent for the Extended Term.
     

 
                                       7

     (b)  Landlord and Tenant shall schedule a meeting no later than fifteen
          (15) days after receipt by Landlord of Tenant's written notice
          exercising its option, to mutually agree on a rent schedule for the
          Extended Term.

     (c)  If Landlord and Tenant are unable to agree on a rent schedule, then
          within five (5) days of the meeting each shall name and appoint a duly
          qualified and licensed real estate appraiser or appraisal firm of
          recognized competence and experience in central and eastern
          Massachusetts. The fees of each appraiser shall be paid by the
          appointing party. If for any reason either Landlord or Tenant do not
          appoint an appraiser by 5:00 PM on the fifth (5th) day, or if the
          fifth (5th) day falls on a Saturday, Sunday or a holiday, by 5:00 PM
          of the next business day, then the party making their appointment may
          request the President of the Greater Boston Real Estate Board or a
          presiding Justice of the Middlesex Superior Court appoint a second
          appraiser. The fee of the second appraiser shall be paid by the non-
          appointing party.

     (d)  Within ten (10) days of their appointment, the two appraisers shall
          appoint a third appraiser of comparable qualifications. If the two
          appraisers cannot agree on a third, then either Landlord or Tenant can
          follow the above procedure for the appointment of the third appraiser.
          The fee of the third appraiser shall be divided equally between the
          parties.

     (e)  The three appraisers shall complete their assignments and establish
          the FMRV for the Demised Premises for the period of the Extended Term
          within thirty (30) days after the appointment of the third appraiser.
          If all three appraisers are unable to agree on the FMRV, then the
          three appraisal reports shall be compared and the percent variance
          between values calculated. The two appraisals with the least variance
          between the values shall be added together and the sum divided by two
          (2), which quotient shall represent the FMRV for the Demised Premises.
          The FMRV shall be expressed in dollars per square foot per year.

     (f)  The Annual Base Rent for the Extended Term is calculated by
          multiplying the FMRV as determined by ninety-five percent (95% or
          .95).

     3.   Late Payment of Base Rent and Additional Rent: The Base Rent and the
Additional Rent shall be considered late if the payment is not received by
Landlord by 5:00 PM on the first day of each month during the Term. Landlord
shall assess and Tenant agrees to pay Landlord, as Additional Rent, a late fee
equal to five (5%) percent of the then monthly rental payment due for both Base
Rent and Additional Rent if payment is made after the fifth day of the month.

                                ARTICLE 5 - Use

     Tenant may use the Demised Premises (i) for general and executive offices;
(ii) for research and development; (iii) for the manufacture and assembly of
products; (iv) for testing and inspection of assembled products; (v) for the
warehousing of both raw materials and finished

 
                                       8

goods related to Tenant's business; and (vi) for corporate sales, training and
demonstration purposes related to Tenant's business ("Permitted Uses"). Tenant
may use the Demised Premises for such other business use in which Tenant might
engage in the future provided that Tenant receives the prior written approval of
Landlord which approval shall not be unreasonably withheld or delayed. It shall
be the Tenant's responsibility to insure that its intended use of the Demised
Premises is in compliance with all laws, codes and regulations throughout the
Primary Term and any Extended Term of this Lease.

any costs incurred by Landlord, its agents, employees and/or contractors arising

referred to in subsections (g), (h), (i), and (k) in the next following
paragraph), Tenant shall pay a share of such costs equal to the percentage

     2.   Landlord shall reasonably estimate the Operating Costs for each
calendar year wholly or partially included within the Term of this Lease. Prior
to the execution hereof, Landlord shall send notice of said estimate to Tenant
for the remaining portion of the first such calendar year and thereafter at
least thirty (30) days prior to the commencement of each subsequent calendar
year. During each calendar year thereafter included in the Term, Tenant shall
pay, as Additional Rent, one twelfth of the applicable estimate each month to
Landlord together with the fixed monthly Base Rent. If Landlord does not give
Tenant such estimate within the time period stated above, then Tenant shall
continue to make estimated payments based upon the preceding year's estimate and
within thirty (30) days after receipt of the new estimate for the current
calendar year, Tenant shall commence payment of the new estimated monthly amount
and shall pay in a lump sum any retroactive amounts due from the beginning of
the new calendar year, except that if such retroactive amount exceeds $25,000,
Tenant shall have the right to pay it in installments over a three (3) month
time period.

          It is agreed between the parties that Landlord may revise its estimate
of Operating Costs once a calendar year to reflect increased costs and shall
give notice to Tenant thereof no later than the tenth (10th) day of the month
preceding the month in which said increased Operating Costs will be applicable.
All payments made hereunder shall be paid to Landlord as stated in this Lease.

     3.   Within one hundred twenty (120) days after the expiration of each
calendar year included in the Term, Landlord shall provide Tenant with a written
statement, in sufficient detail for verification by Tenant, comparing the actual
Operating Costs for the preceding calendar year

 
                                      12

against the estimate of Operating Costs for the current calendar year. Within
thirty (30) days after the delivery of such statement, including any statement
delivered after the expiration or termination of this Lease, Tenant shall pay to
Landlord the difference, if any, between the amount paid by Tenant as estimated
Operating Costs and the amount owed by Tenant for the actual Operating Costs for
such lease year, provided, however, that if Landlord does not furnish Tenant
with a statement within six (6) months after the end of the billing period for
Operating Costs, Tenant shall not be obligated to pay such amount. If Tenant's
payment of the estimated Operating Costs was greater than the amount owed by
Tenant for the actual Operating Costs, then Landlord shall pay same to Tenant
within thirty (30) days after delivery of such a statement.

          Tenant shall notify Landlord within sixty (60) days after receipt of
Landlord's statement of its intention to inspect Landlord's books and records
with respect to Landlord's maintenance and operation of the Property for the
purpose of verifying the actual Operating Costs and their inclusion and Landlord
shall promptly thereafter provide Tenant with access to such records. Tenant,
its accountant, or a qualified consultant engaged by Tenant, at Tenant's sole
cost, shall conduct and conclude its inspection of Landlord's books and records
with respect to Landlord's maintenance and operation of the Property within
thirty (30) days after Tenant's notice and access and shall be entitled, at its
expense, to make copies thereof. If such inspection reveals that Tenant's
payment of the estimated Operating Costs was greater than the amount owed by
Tenant for the actual Operating Costs, then Landlord shall pay same to Tenant
within sixty(60) days after receipt by Landlord of a written notice from Tenant
identifying the nature and amount of any overpayment.

     4.   If, during the Term of this Lease, Landlord shall make

          (i)  a Capital Expenditure, hereinafter defined, for an improvement
which produces a cost savings in operating the Land and/or Demised Premises and
of which Landlord has given information reasonably satisfactory to Tenant
demonstrating a cost savings greater than Tenant's Proportionate Share of the
Annual Amortization of such improvement as stated in the following sentence; or

          (ii) a Capital Expenditure to the Property which benefits the Demised
Premises and/or to the Demised Premises, which is required: a) to comply with
changes in laws applicable to the Property and/or the Demised Premises, or b) as
a result of an alteration or improvement performed by Tenant, except for any
such Capital Expenditure made as a result of an obligation of Landlord pursuant
to this Lease, which shall be done at Landlord's sole expense without any
reimbursement from Tenant; then Tenant shall pay Tenant's Proportionate Share of
the Annual Amortization of such Capital Expenditure. The Annual Amortization
shall be determined by dividing the cost of the original Capital Expenditure
plus an interest factor, reasonably determined by Landlord as being the interest
rate then being charged for long-term mortgages by institutional lenders on like
properties within the locality in which the Demised Premises are located, by the
number of years of the useful life of the Capital Expenditure in accordance with
GAAP.

 
                                      13

          With respect to the payment of Tenant's Proportionate Share of the
Annual Amortization, Tenant shall commence payment as Additional Rent of one
twelfth (1/12th) of the annual amount shown in Landlord's notice given pursuant
to the immediately preceding sentence with the next and each succeeding
installment of rent becoming due during the Term, provided that the item for
which the expenditure was made has been fully completed on the date of Tenant's
first payment and further provided that Tenant has received notice of such
amount at least fifteen (15) days prior to the month in which payment is first
due or if not so received, then Tenant's payment shall commence as of the
following month. For purposes of this Lease, a "Capital Expenditure" is defined
as the acquisition of a prior non-existing asset or the acquisition of a
replacement of a pre-existing asset not acquired in the ordinary course of
business and not characterized as an operating cost or expense within generally
accepted accounting principles, provided that the acquired asset must enhance
the value of the real estate over its useful life, be permanently affixed to the
real estate and excludes all personal property, removable trade fixtures and
repairs to existing assets.

     5.   Notwithstanding any provisions in this Lease to the contrary, Landlord
shall perform all maintenance, repairs and replacements necessary to keep in
good condition and working order and in compliance with all applicable laws,
ordinances and regulations (a) the roof, foundation, columns and other
structural elements of the Building, (b)the heating, ventilating, air
conditioning, plumbing, electrical, life safety and other mechanical systems and
equipment serving the Building, (c) the parking areas on the Land (including
snow removal), (d) the driveways and walkways necessary for access to the
Building or the Demised Premises or such parking areas (including snow removal),
(e) the entrances (including snow removal), necessary for access to the Building
and Demised Premises, (f) the loading docks and passenger elevators in the
Building, (g) the lavatories in the Demised Premises, and (h) any common areas
and facilities provided by Landlord from time to time. When Landlord performs
maintenance, repair and replacement work, Landlord shall take care not to
unreasonably interfere with Tenant's use of the Demised Premises. If Tenant's
use of the Demised Premises is materially adversely affected for more than three
(3) consecutive business days as a result of Landlord's breach of its repair
obligations as set forth herein, then Tenant shall be entitled to an equitable
abatement of rent for each such consecutive business days that Tenant's use is
materially adversely affected.

     6.   As used herein, Real Estate Taxes shall mean general real estate taxes
levied against the Property but not any special assessments or taxes in the
nature of improvement or betterment assessments which shall be governed solely
by Paragraph 6.9. Real Estate Taxes shall also exclude, without limitation, any
income, franchise, gross receipts, corporation, capital levy, excess profits,
revenue, rent, inheritance, devolution, gift, estate, payroll or stamp tax by
whatsoever authority imposed or howsoever designated or any tax upon the sale,
transfer and/or assignment of Landlord's title or estate which at any time may
be assessed against or become a lien upon all or any part of the Demised
Premises, or this leasehold. In addition, Real Estate Taxes shall exclude any
liens or taxes, penalties or interest which are levied or assessed against the
Property for a period of time prior to the commencement of the Term or one
levied or assessed for a period during the Term on account of late payment not
caused by Tenant, or any related fees or costs, and shall also exclude all or
any portion of the Real Estate Tax Arrearage,

 
                                      14

except for Tenant's Proportionate Share of Real Estate Taxes for Fiscal Year
1998 not previously paid by it.

     7.   If at any time during the Term the laws concerning the methods of real
property taxation prevailing at the commencement of the Term are changed so that
a tax or excise on rents or any other such tax, however described, is levied or
assessed against Landlord as a direct substitute in whole or in part for any
Real Estate Taxes, Tenant shall pay before delinquency (but only to the extent
that it can be ascertained that there has been a substitution and that as a
result Tenant has been relieved from the payment of Real Estate Taxes it would
otherwise have been obligated to pay) the substitute tax or excise on rents.

     8.   Tenant shall pay monthly, as part of the Additional Rent described in
Paragraph 6.2 above, Tenant's Proportionate Share of all Real Estate Taxes as
estimated by Landlord based on the tax bill for the current tax year to be
assessed against the Property for each fiscal tax year or such other tax period
as may be defined by the appropriate governmental authority having jurisdiction
or portion thereof included within the Term, and which are during such Term,
levied, or imposed upon or become a lien or liens upon the Property or any part
thereof. This part of the Additional Rent payment shall be one twelfth of the
applicable annual estimate.

          Real Estate Taxes for the tax year in which the Term of this Lease
commences and for the tax year in which such Term expires shall be apportioned
between Landlord and Tenant in accordance with the number of days thereof
falling within the Term of this Lease.

     9.   Landlord shall pay when due all special assessments and betterment
assessments for municipal improvements levied against the Property or any part
thereof during the Term. Landlord may elect to either i) pay the assessments in
full, or ii) pay in installments over the period of time and upon the terms
offered by the assessing authority.

          Tenant shall pay Tenant's Proportionate Share of any such assessments
which shall be calculated as follows: 1) using Tenant's Proportionate Share as
identified in Exhibit A -Schedule of Space and Exhibit A-2 - Building Complex
Space Allocation, 2) multiplied by the amount of the assessment attributable to
the Property, 3) divided by the maximum number of installments allowed or
allowable by the assessing authority, 4) multiplied by the interest rate
(monthly or annual) as stated by the assessing authority. Payment of any such
installment of an assessment shall be made in accordance with the Article 6.8
above.

     10.  Landlord is solely responsible for the timely payment of Real Estate
Taxes and any special assessments or betterment assessments to the Town of
Maynard. So long as no lien will be placed against the Property, Landlord, at
its sole election and its sole cost, may contest the amount of real estate taxes
to be paid, file for an abatement of real estate taxes paid, file an appeal of
the decision of the local Board of Assessors to the State Appellate Tax Board or
file a suit in a court having jurisdiction over such matters. Should Landlord
receive an abatement or an award from the court for amounts levied or assessed
for a period falling within the Term, then Landlord shall pay to Tenant Tenant's
Proportionate Share of such amount after deduction of expenses incurred in
connection therewith.

 
                                      15

     11.  Landlord acknowledges that it currently owes real estate taxes and
water and sewer charges due with respect to the Property (collectively,
"Outstanding Taxes") for periods of time prior to the commencement of the Term,
as well as interest, fees, penalties and costs relating to such Outstanding
Taxes, and taxes and water and sewer charges for Fiscal Year 1998 (all such
amounts, as well as any assessments or other amounts, outstanding with respect
to the Property for any period of time prior to the Date of Execution, including
penalties and interest, collectively, referred to as the "Real Estate Tax
Arrearage"). As a material inducement to Tenant's willingness to execute this
Lease, Landlord has agreed (a) to pay to the Town of Maynard, or other
appropriate entity, the entire Real Estate Tax Arrearage on or before July 7,
1998; and (b) to provide to Tenant on or before July 8, 1998 written
verification of its payment in full of all such amounts, as well as written
verification from the Town of Maynard that it has accepted such amounts as
payment in full (such written verification referred to as the "Tax Payment
Notice"); and (c) to provide to Tenant on or before July 15, 1998 written
verification from the Town of Maynard of Tenant's and Landlord's ability to
obtain a building, occupancy, or other local permit or license for performing
alterations or improvements at, and/or the occupancy by Tenant of, the Demised
Premises (collectively, "Permits") and of the removal of any conditions or
restrictions on (or the denial, suspension or revocation of) the issuance of any
Permits resulting from the Real Estate Tax Arrearage (such written verification
referred to as the "Building Permit Notice"). In the event that Landlord has not
timely performed all of its obligations under this Section 6.11, Tenant shall be
entitled to exercise its Early Termination Right pursuant to Section 3.3.
Notwithstanding the foregoing, Landlord shall be entitled to seek relief against
the Town of Maynard with respect to such amounts so long as such actions or
litigation shall not affect Landlord's obligations in subsections (a) - (c)
above or Tenant's ability to obtain any Permits.

     12.  If the Term or Extended Term includes any partial calendar year, the
Additional Rent for such calendar year shall be prorated according to the
fraction of total days in such calendar year that are included in the Term or
Extended Term. If the Term or Extended Term begins on a day other than the first
day of a calendar month or ends on a day other than the last day of a calendar
month, then the monthly installment of Additional Rent for the month in which
the Term begins or ends shall be prorated at the rate of 1/30 of the then
current installment of Additional Rent for each day in such month.

                       ARTICLE 7- Utilities and Services

     1.   Landlord shall supply to the Building Complex, of which the Demised
Premises is a part, at no cost to Tenant, except as it may otherwise be provided
Sections 6.1,6.2 and 7.2 in this Lease, the following services, which shall be
available 24 hours per day, 7 days per week: gas, hot and cold running water for
lavatory, cooking and drinking purposes, sewer services, heating, ventilating
and air conditioning ("HVAC"), and electricity for lighting and the operation of
Tenant's business equipment and machines. HVAC service shall be provided 8 a.m.
to 6 p.m. Monday through Friday throughout the entire Demised Premises, and at
other hours to portions of the Demised Premises, at Tenant's request, through
the energy management system at the Property (the "EMS"). The Landlord shall
provide that the heating system serving the Demised Premises shall heat all
areas of the Demised Premises to an inside temperature of seventy (70) degrees
Fahrenheit when the outside temperature is zero (0) degrees Fahrenheit or above,
and

 
                                      16

that the air-conditioning equipment will be of sufficient capacity to cool the
Demised Premises to seventy-five (75) degrees Fahrenheit plus or minus two (2)
degrees with a relative humidity of fifty percent (50%) plus or minus five
percent (5%) and the outside temperature is ninety-five (95) degrees dry bulb,
seventy-three (73) degrees wet bulb.

     2.   Tenant shall be responsible for the payment of all utility expenses
for those utilities serving the Demised Premises associated with the use and
occupancy of the Demised Premises including water, sewer, electricity, fuel oil
or gas. Tenant will be charged by Landlord for its actual usage of utilities as
part of the Operating Costs and which Tenant shall pay monthly as part of the
Additional Rent, described in Paragraph 6.2. Landlord represents that gas, water
and sewer service for Building No.3 are currently separately metered and that
Landlord shall, at its sole cost and expense, separately sub-meter the electric
utilities provided to Building No.3 and connect such submeter to the EMS, on or
before July 1, 1998. For any utility service provided to all or any portion of
the Demised Premises which are separately metered or submetered, Tenant shall be
charged for its actual usage as shown on such meter or sub-meter, without mark-
up.

     For any period during which any utility service provided to all or any
portion of the Demised Premises is not separately metered or sub-metered, Tenant
shall pay for such utility service, as follows. If such utility service is
provided to all tenants at the Building Complex, Tenant's share shall be
Tenant's Proportionate Share. If such utility service is provided to some, but
not all, tenants at the Building Complex, Tenant's share shall be a fraction,
the numerator of which is the square feet of the Demised Premises at the time
such service is provided and the denominator of which is the total square feet
of the premises to which such service is provided. Notwithstanding the
foregoing, if Tenant's usage significantly increases on a per square foot basis
over its current usage with respect to utilities which are not separately
metered or sub-metered, Landlord may reasonably adjust Tenant's share.

     3.   Tenant shall make its own arrangements with any utility company not
servicing the Demised Premises for any utilities that it desires that are
currently not being provided by Landlord (Landlord is not aware of any such
utility), and shall pay when due any and all charges for services supplied to
Tenant by the respective utility. In the event that Landlord is notified that a
lien will be placed against the Demised Premises as a result of Tenant's failure
to pay any such utility charge, then Landlord shall immediately notify Tenant of
the impending lien and to protect the real estate Landlord may pay such charges,
notify Tenant thereof and the same shall be paid by Tenant as Additional Rent
with the next installment of Base Rent becoming due.

     4.   In no event shall Landlord be responsible for charges for any
utilities consumed by Tenant at the Demised Premises.

     5.   Landlord shall use reasonable efforts to work with the utility
providers to restore any service which becomes unavailable. If, however, such
unavailability of any utility service has a material adverse effect on Tenant's
use and occupancy of the Demised Premises for more than ten (10) consecutive
business days, then after the tenth (10th) day Tenant shall be entitled to

 
                                      17

an abatement of fifty percent (50%) of the Base Rent as prorated on a per diem
basis for each consecutive day that Tenant's use is so affected.

     6.  Landlord shall provide property management services for the Property
and the Demised Premises as provided for in Article 6 above and shown on Exhibit
B. Tenant is responsible for Tenant's Proportionate Share of the cost of said
services, the amount of which shall be identified on the Operating Cost estimate
to be delivered to Tenant as provided for in Article 6.2 above and paid monthly
as part of Additional Rent. The property management services to be rendered by
Landlord set forth in this Article shall be provided between the hours of 8 AM
and 5 PM Monday through Friday. If Tenant requires any property management
services to be performed after said hours, including Saturdays, Sundays and
holidays, Tenant shall notify Landlord of such requirement no later than 3 PM on
any week day and by 3 PM on Friday for after hours service on Saturday and/or
Sunday. The cost for such additional service shall be as provided for in Article
6.1 above

      ARTICLE 8 - Condition of the Premises, Landlord and Tenant Improvements

     1.  Condition of the Premises:

     (a) Tenant agrees to take and Landlord agrees to deliver the Demised
Premises according to Exhibit A; Schedule of Space, upon the Commencement of
this Lease, in the "as is, where is" condition, subject to Landlord's
obligations under this Article 8 and 6.5 hereof. On such date or the dates
identified in Exhibit A; Schedule of Space, or such earlier occupancy date as
provided in Article 2, the Demised Premises shall be free of all occupants and
their personal property, in good basic operating condition and repair, broom
clean and in compliance with applicable building, life and safety codes.

     (b) In addition to the foregoing, Landlord shall, on or before July 1,
1998 (a) insure that Andataco, Inc., and any other persons, currently using the
vestibule and lobby on the first floor of the Building have vacated and ceased
all use of or operation within such areas, as well as any access to or through
the lobby and vestibule, removing all signage and leaving the same in broom
clean, good condition and (b) construct a demising wall in the loading dock area
of the Connector Building, separating the Demised Premises from the remainder of
the Connector Building, as previously agreed. Landlord further agrees that it
shall, on or prior to June 1, 1998, remove from the third floor portion of the
First Additional Premises, all equipment, supplies, materials and all other
personal property.

     (c) Subject to the provisions of Article 2 relating to Early Space,
Landlord will, prior to August 1, 1998, perform the following improvements in
the third floor portion of the First Additional Premises ("Landlord Work"):
install new carpeting and ceiling tiles; paint walls; refurnish existing light
fixtures; demolition of certain demising walls as shown on a plan prepared by
John Brennan, architect, previously approved by Landlord and Tenant; and clean
and paint bathrooms. The quality and type of materials and workmanship will be
similar to the Initial Demised Premises. Landlord will have no obligation to
install any hard wall partitions or to modify the HVAC, electrical or
telecommunications system as part of Landlord Work.

     2.  Landlord Improvements and Repairs: HVAC and Air Quality:

 
                                      18

     Landlord shall promptly and diligently make whatever improvements are
necessary to correct air quality problems with respect to the Demised Premises,
including addressing the problems identified in the Envirohealth Report issued
May 19, 1997. Such improvements shall include, but are not limited to:

     (a)  HVAC System

          (1)  Landlord shall provide ventilation of the Demised Premises that
               meets or exceeds the Standards for Acceptable Indoor Air Quality
               (ASHRAE 62-1989) established by the American Society of Heating,
               Refrigeration and Air-Conditioning Engineers, as such Standards
               may be amended from time to time (the "Standards"). If the
               ventilation system serving the Demised Premises fails to provide
               adequate ventilation according to the Standards, Landlord shall
               promptly and diligently make such repairs or replacements to the
               ventilation system as are necessary to comply with the Standards.

          (2)  Prior to the date hereof, Landlord has installed four (4) new
               HVAC units on the roof of Building No.3. The specifications for
               the new units includes:

               a.   Economizers pre-set to provide fresh air (outside) make up
                    at approximately fifteen percent (15%),

               b.   Power exhausts to provide proper pressure stabilization and
                    air exchange.

               c.   Humidity controls to provide for humidity levels between
                    forty-five and sixty percent (45% to 60%).

          (3)  The cost of the new HVAC units and the cleaning of the HVAC duct
               work and their installation shall be at Landlord's sole cost and
               expense and shall not be amortized and payable by Tenant as
               Additional Rent as provided for in Article 6.4 above.

          (4)  Landlord shall, throughout the Term of the Lease, be responsible
               for the inspection, repair and maintenance of the HVAC system
               serving the Demised Premises, including the two (2) units which
               are located on the roof of the Connector Building, which serve
               the Tenant's second floor computer room. Tenant shall pay
               Tenant's Proportionate Share of said expenses as provided for in
               Article 6 above. In the event that the new HVAC units serving
               Building No.3 described above (as well as the new HVAC unit
               located on the roof of Building No.3 and serving Tenant's third
               floor computer room) require repairs or replacements during the
               Term or Extended Term, Landlord shall first seek coverage or
               reimbursements for said repairs or replacements from any warranty
               or

 
                                      19

               guaranty that may be in effect at that time before seeking
               reimbursement from Tenant. Landlord represents that all such new
               units are covered by a five (5) year warranty. It is understood
               by both parties that normal preventive maintenance practices
               including but not limited to oiling of motors, changing belts and
               replacing filters are not covered by a new HVAC unit warranty.

     (b)  HVAC Duct Cleaning:

          After the installation of the new HVAC units, Landlord engaged a
          qualified consultant to clean the HVAC ducts in Building No.3 as
          recommended in the EnviroHealth Report (#809-849b), issued May 19,
          1997. During this process, the consultant installed after-filters in
          the supply grills to enhance the collection of airborne dust
          particles.

     3.   Air Quality Monitoring:

          Landlord shall (a) at Landlord's sole expense, within a reasonable
amount of time following the HVAC duct cleaning (as set forth below), and at
three (3) year intervals thereafter, and (b) at Tenant's request and at Tenant's
sole expense, at other times, engage an indoor air quality professional, subject
to Tenant's approval which approval shall not be unreasonably withheld or
delayed, to inspect the HVAC system and/or conduct air quality tests, if
appropriate. Landlord shall promptly correct any problems identified by such air
quality professional. Landlord shall require such air quality professional to
provide copies of any and all reports and test data to Tenant. The first such
inspection and testing (which shall include the HVAC duct work and HVAC
machinery pans and sumps) shall be performed at Landlord's expense, and all
reports and test data delivered to Tenant by September 1, 1998.

     4.   Landlord Improvements - General:

          Landlord in making any improvements, alterations, construction or
other work, including Landlord Work, shall cause all work to be done in a good
and workmanlike manner using materials equal to or better than those used in the
construction of the Demised Premises and shall comply with or cause compliance
with all applicable building codes, health and safety regulations and zoning
laws and with any direction given by any public officer pursuant to such codes,
regulations and laws. Landlord shall obtain or cause to be obtained and maintain
in effect, as necessary, all building permits, licenses, temporary and permanent
certificates of occupancy and any other governmental approvals which may be
required in connection with the making of the improvements, alterations,
construction or other work.

     5.   Default by Landlord:

          In the event that Tenant notifies Landlord of any defaults on its
obligations under this Article, and Landlord shall fail to cure the same within
fifteen (15) days after receipt of such notice (or, as to a default under
Subsection 2(a)(4) which is not within Landlord's control, forty

 
                                      20

(40) days after receipt of such notice, Tenant shall have the right to terminate
the Lease, upon fifteen (15) days written notice to Landlord.

     6.   Tenant Improvements:

     (a)  Prior to making any initial improvements to any portion of the Demised
          Premises ("Tenant Improvements"), Tenant shall give Landlord notice of
          its intentions and submit plans and specifications of the proposed
          Tenant Improvements to Landlord, for approval, which approval shall
          not be unreasonably withheld or delayed. Landlord acknowledges that
          the Tenant Improvements may include the following work:

          .  Upgraded cafeteria.

          .  Relocation of demonstration room and training room.

          .  Exercise room with shower.

          .  Relocation of existing and/or construction of new laboratories.

          .  Enlarge third floor computer room, including additional air
             conditioning and installation of condenser(s) on roof.

          .  Installation of a new card reader security system, separate from
             the current Andataco system, including electrical and low voltage
             wiring. This may include expansion of the current system in the
             manufacturing area of the first floor of the Demised Premises.

          Landlord's approval shall be deemed given if Landlord does not respond
          to Tenant's request for approval within fifteen (15) days from the
          receipt of such request. In the event that Landlord withholds approval
          for the proposed Tenant Improvements, Landlord shall state in writing
          its reasons in sufficient detail to permit Tenant to modify its plans
          in order to receive approval.

     (b)  At the time Landlord grants or is deemed to grant approval of any
          Tenant Improvements, Landlord shall inform Tenant of any of the Tenant
          Improvements that would (i) materially diminish the value of the
          Demised Premises for use by a tenant for the Permitted Uses or (ii)
          require unusual expenses to readapt the Demand Premises for use by a
          tenant for the Permitted Uses or (iii) would be unique to Tenant's
          particular business operations (except for the air handlers in
          Tenant's computer rooms), and must be removed at the end of the Term.
          If Landlord does inform Tenant of any such removal requirements, then
          Tenant may either remove or leave such Tenant Improvements as it
          decides. Tenant's responsibility upon removal of any such Tenant
          Improvement is to repair any damage caused by the removal and not to
          restore the Demised Premises.

 
                                      21

     (c)  Tenant Improvements may be done by any contractor chosen by Tenant and
          approved by Landlord which approval shall not be unreasonably withheld
          or delayed. Said contractor must be licensed, carry the kinds or
          insurance and in the amounts set forth in subparagraph (f) below, and
          must not interfere with Landlord's performance of its obligations
          under this Lease.

     (d)  If Tenant retains Landlord to perform any of the work of making
          Tenant. Improvements for Tenant, Landlord shall obtain bids from three
          (3) independent general contractors. If Landlord acts as its own
          general contractor, it shall obtain three (3) bids from three (3)
          independent subcontractors for each discipline (mechanical,
          electrical, etc.). Landlord shall make its recommendation as to each
          bidder, however, Tenant shall have the right to choose the successful
          bidder in either event. If Landlord acts as its own general
          contractor, Landlord shall not receive more than ten percent (10%)
          overhead and profit based on the total cost of construction.

     (e)  Tenant in making any Tenant Improvements shall cause all work to be
          done in a good and workmanlike manner using materials equal to or
          better than those used in the construction of the Demised Premises and
          shall comply with or cause compliance with all applicable building
          codes, health and safety regulations and zoning laws and with any
          direction given by any public officer pursuant to such codes,
          regulations and laws. Tenant shall obtain or cause to be obtained and
          maintain in effect, as necessary, all building permits, licenses,
          temporary and permanent certificates of occupancy and any other
          governmental approvals which may be required in connection with the
          making of the Tenant Improvements. Landlord shall cooperate with
          Tenant in the obtaining thereof and shall execute any documents
          reasonably required in the furtherance of such purpose, provided any
          such cooperation shall be without expense and/or liability to
          Landlord.

     (f)  Tenant shall have its contractor procure and maintain in effect during
          the term of such Tenant Improvements, the following insurance
          coverages with an insurance company or companies with a Best's rating

          change in, cancellation or non-renewal of any policy.

     (g)  All Tenant Improvements shall be at Tenant's sole cost and expense.

     (h)  Tenant may make additional alterations, additions and improvements in
          accordance with Article 9 below.

     7.   Installation of Tenant's Microwave Dishes on Roof:

          Prior to the date hereof, Tenant has installed on the roof of Building
No.3 two (2) microwave dishes. Landlord hereby acknowledges its consent to such
installation. Landlord also acknowledges Tenant's intention, either as part of
its initial improvements to the First Additional Premises or as subsequent
alterations to install additional microwave dishes on the roof of Building No.3,
which installation may include roof penetration, and on the roof of the Building
No.1, in the event that Tenant exercises its Expansion Right under Section
32(b), but without roof penetration. Any such microwave dish shall be for
reception and not transmission and shall be used only by Tenant or its
affiliates or its successors or assigns and not third parties and shall meet all
applicable Town requirements. Landlord hereby consents to Tenant's installation
of such dishes so long as Tenant complies with the provisions of Article 2,
Section 8.6 and Article 9 if applicable.

     8.   Elevator and Lobby:

          Landlord agrees that it will not construct any improvements on or near
the outside of Building 3, including, without limitation, a new elevator and
lobby. Landlord shall have access to the interior of the Demised Premises during
the last nine (9) months of the Term (or Extended Term) solely for measuring and
preparing plans for alterations to be performed by

 
                                      23

Landlord after the expiration of the Term (or Extended Term), so long as there
is no disruption of or interference with Tenant's operations.

              ARTICLE 9 - Alterations, Additions and Improvements

     Upon completion of the initial Tenant Improvements to any portion of the
Demised Premises, Tenant may, from time to time, at its own cost and expense and
without the consent of Landlord make alterations, additions or improvements
(collectively herein called "Alterations") of a non-structural nature to the
Demised Premises which cost in any one instance is Ten Thousand and 00/100
Dollars ($10,000.00) or less, provided Tenant first notifies Landlord in writing
of any such Alterations. If Tenant desires to make any structural Alterations
costing any amount or any non-structural Alterations which costs in any one
instance exceed Ten Thousand and 00/100 Dollars ($10,000.00), Tenant must first
give Landlord notice of its intentions and submit plans and specifications of
the proposed Alterations to Landlord, for approval, which approval shall not be
unreasonably withheld or delayed. With respect to all of the other aspects of
any proposed Alterations, including Landlord approvals, selection of
contractors, the Landlord as contractor, materials and workmanship, licenses and
permits, and the insurances to be carried, the provisions of Article 8.4(a)
through (g) above apply. Such alterations may include, without limitation, some
or all of the items referred to in Section 8.6(a).

                       ARTICLE 10 - Compliance with Laws

     1.  Tenant shall be responsible throughout the Term or Extended Term for
procuring all licenses and permits for the Demised Premises required for the
operation of Tenant's business including Tenant's sign. Tenant agrees that it
shall do nothing, during the Term or Extended Term, in its use and occupancy of
the Demised Premises which would cause the Demised Premises to be in non-
compliance with any applicable governmental laws, codes, ordinances, rules and
regulations to the extent the same apply to Tenant's use and occupancy of the
Demised Premises as opposed to laws of general applicability. In the event that
Tenant receives notice of non-compliance with laws relating to Tenant's use and
occupancy, as provided for in Article 5, by any governmental authority having
jurisdiction over the Property, Tenant shall diligently pursue remediation of
the problem and shall correct the non-compliance within the period of time
prescribed by the governmental authority unless it is determined that such
remediation and correction work falls within the Landlord's responsibilities and
obligations under this Lease whereupon Tenant shall provide Landlord with
written notice of the non-compliance and identify Landlord's responsibilities
and obligations under the Lease.

     2.  Tenant shall have the right, at its expense, to contest, by appropriate
legal proceedings conducted in good faith with due diligence, the validity or
applicability, in whole or in part, of any governmental laws, codes, ordinances,
rules and regulations pursuant to which such notice of non-compliance was
issued, and, so long as such proceedings are being conducted in good faith and
with due diligence Tenant may defer compliance therewith pending the outcome of
that contest provided that such deferral shall not: i) result in any deprivation
in the use of the Property by any party entitled thereto; or ii) result in any
criminal or civil liability on the part of the Landlord. Landlord shall, upon
request by Tenant, cooperate with any such

 
                                      24

contest provided that Tenant shall pay all actual out-of-pocket costs incurred
by Landlord in connection therewith.

     3.  In the event that a capital expenditure is required to make an
Alteration to the Demised Premises so that it is in compliance with all
statutes, codes, regulations and other laws as a result of Tenant's use of the
Demised Premises (excluding any Capital Expenditures which fall within
Landlord's responsibilities and obligations under this Lease included in Article
6 and 8), Tenant shall be responsible for making any such expenditure and
Alteration. Upon receipt of notice of non-compliance by any governmental
authority having jurisdiction over the Demised Premises, Tenant shall diligently
pursue remediation of the problem and shall correct the noncompliance within the
period of time prescribed by the governmental authority. The provisions of
Article 8.6 and 9 above apply in the remediation of any non-compliance. Landlord
agrees to cooperate fully with Tenant in correcting the item(s) of non-
compliance.

     4.  In the event that Landlord receives notice of non-compliance with any
law, ordinance, code, rule or regulation relating to the Land and/or Building
(and any systems therein) and/or the Property by any governmental authority
having jurisdiction over the Property, Landlord shall diligently pursue
remediation of the problem at its expense subject to the provisions of Article
6.4 and shall correct the non-compliance within the period of time prescribed by
the governmental authority.

                      ARTICLE 11 - Damage and Destruction

     1.  In the event of damage or destruction to all or part of the Demised
Premises or Building by fire or other casualty (collectively, a "casualty"), or
if Tenant's access ("Access") to or use and occupancy of the Building, Demised
Premises, parking area or Common Areas of the Property is interfered with due to
a casualty, Tenant shall notify Landlord thereof as soon as possible after
Tenant becomes aware thereof.

     2.  Landlord or Landlord's managing agent shall have a period of thirty
(30) calendar days from receipt of Tenant's notice pursuant to the first
paragraph of this Article to give Tenant a good faith estimate ("Estimate") of
the time required to repair the casualty and restore Access and/or Tenant's use
and occupancy of the Building, Common Areas, and the Demised Premises to their
condition existing immediately prior to the Casualty. The Estimate shall be
based on the following information, if available: Landlord's own estimate, at
least one independent contractor, and a report from the insurance adjuster
representing the insurance company insuring the Property. If the Estimate is for
a period equal to or more than ninety (90) days, the Casualty is hereby deemed
substantial. If the Estimate is for a period of less than ninety (90) days, the
Casualty is hereby deemed partial.

     3.  If the Demised Premises, or the Building, suffers a partial Casualty
and Tenant's use and occupancy of the Demised Premises and/or Access can be
restored within ninety (90) days, Landlord shall completely repair and restore
same. If Landlord does not substantially complete the repair and restoration
within the Estimate period plus ten (10) days (measured from the date of
Tenant's receipt of the Estimate), Tenant has the right to terminate this Lease
on ten (10) days written notice to Landlord provided that any delay in the
completion of the work on the

 
                                      25

part of Landlord must be within Landlord's control, or 40 days written notice if
such delay is not within Landlord's control.

     4. If there is a substantial Casualty to the Demised Premises, the
Building, or the Access and Tenant's use and occupancy cannot be restored within
ninety (90) days, either Landlord or Tenant has the right to terminate this
Lease on ten (10) days written notice to Landlord after Tenant's receipt of the
Estimate. If neither party terminates this Lease, then Landlord shall proceed to
promptly repair and restore such damage, destruction or hindrance to Access.

     5.  From the date of such partial or substantial Casualty, a proportionate
part of the Base Rent and Additional Rent, according to the nature and extent of
the interference with Tenant's use and occupancy of or Access to the Demised
Premises shall be equitably abated until the repair and restoration have
occurred. In the event this Lease is terminated as hereunder provided, Tenant
shall pay the Base Rent and Additional Rent prorated to the date of such partial
or substantial Casualty and thereafter, Tenant shall be relieved of all further
liability for the payment thereof.

     6.  Notwithstanding anything to the contrary in this Lease, if the Estimate
is for a period extending beyond the remainder of the Term, either Landlord or
Tenant may terminate this Lease upon ten (10) days written notice to the other,
provided, however, that Landlord may not exercise this right if Tenant has
previously exercised or provides immediate exercise of the extension option
contained in this Lease and within the prescribed time frame defined in Article
3.2 above.

     7.  In the event that the Demised Premises or the Building suffers either
partial or substantial Casualty, the parties have not exercised their respective
rights to terminate this Lease, and Landlord has proceeded to repair and restore
the damage or destruction caused by a Casualty at its own cost and expense, then
Landlord shall be entitled to recover the cost of the repair and restoration
from the following sources:

     (a) The insurance proceeds up to the limit of coverage.

     (b) Any cost not covered by insurance including costs resulting from a
         shortfall in insurance coverage and/or the cost of any deductibles
         shall be the responsibility of the party deemed to be at fault, either
         by a willful or negligent act, as determined in the appropriate
         judicial forum.

                           ARTICLE 12 - Condemnation

     1.  In the event of a taking by condemnation or by the exercise of the
power of eminent domain by a public or quasi-public authority or entity or
conveyance in lieu thereof (all hereinafter referred to as "Taking") of the
entire Demised Premises, or of the entire Building or of the entire parking area
serving the Building, or of the entire Access thereto, either by fee title or
easement, either party may terminate this Lease by giving written notice to the
other party, and this Lease shall terminate on the date that title vests in the
Taking authority or that such Taking

 
                                      26

authority takes physical possession so as to deprive Tenant of the use thereof
without the necessity for any further act or notice by either party hereto.

     2.  In the event of a partial taking of the Demised Premises, the Building,
the parking area serving the Building, or the Access thereto, either by fee
title or easement, that, in Tenant's judgment reasonably exercised, results in a
material interference in the conduct of Tenant's business operations, Tenant
shall have the right to terminate this Lease upon written notice to Landlord
within thirty (30) days of the Taking. The effective date of the termination
shall be the later of the Taking or fifteen (15) days after the date of such
notice.

         Notwithstanding the foregoing, if the parking area serving the
Building is the subject of the Taking resulting in a reduction of the number of
parking spaces available to Tenant, Landlord may suspend the effectiveness of
such notice by giving its own notice to Tenant within ten (10) days of receipt
of Tenant's termination notice that Landlord shall provide substitute parking
spaces equal to the number taken with sixty (60) days of the Taking.

     3.  In the event this Lease is not terminated as a result of a Taking: (i)
Base Rent and Additional Rent payable hereunder shall abate from the earlier
date of vesting of title or the date of possession by such Taking authority
whether or not there is divestiture of title; such abatement of Base Rent and
Additional Rent shall be in proportion to the amount of the Demised Premises or
Building or Property subject to a Taking and shall be permanent in the case of
divestiture of title; and there shall be no abatement of Base Rent and
Additional Rent for the Taking of parking spaces; and (ii) Landlord shall
commence the work of repairing and restoring the Building to a complete
architectural unit and useable by Tenant as allowed under this Lease, the work
of restoring the remainder of the Demised Premises as nearly as possible to
their condition existing immediately prior to the Taking, and to restore Access
to the Building and Demised Premises or provide alternative Access thereto, all
such work to be commenced within thirty (30) days of possession by the Taking
authority and completed within ninety (90) days ("Work Date") of the effective
date of such possession. If Landlord does not substantially complete the repair
and restoration within the time herein provided, Tenant has the right to
terminate this Lease by giving notice to Landlord within fifteen (15) days of
the Work Date effective on the date specified in the notice, which date shall
not be more that fifteen (15) days from the date of the notice to Landlord
provided that any delay in the completion of the work, on the part of Landlord
must be within Landlord's control.

     4.  In the event of a Taking, Tenant shall, within ten (10) days of the
effective date of the termination of this Lease or the effective date of the
abatement of Base Rent and Additional Rent, as the case may be, receive a refund
from Landlord of the appropriate Base Rent and Additional Rent amount paid by
Tenant prior to the effective date of termination or abatement for any period
subsequent to the effective date of termination or abatement.

real or personal property of Landlord or Tenant, regardless of cause or origin
to the extent of any recovery from any insurance policy. Landlord and Tenant
agree that any policies obtained on or after the date hereof shall include a

Landlord shall not cure such default within thirty (30) days after receipt of
written notice thereof (the "Default Notice") from Tenant, or shall not within
said period commence to cure and thereafter diligently prosecute the curing of
such default to completion, then Tenant may, at its option, after it has given
Landlord at least five (5) days prior written notice of its intent to cure (the

Landlord. The Self-Help Notice maybe sent any time after the expiration of 25

wrongly invokes its right herein contained, Landlord's relief shall be the
payment by Tenant of all installment of Base Rent withheld by it plus a penalty

                         ARTICLE 32 - Expansion Right

     In addition to the rights and obligations set forth in Section 33.2,
Landlord agrees that neither Landlord nor any of its agents, employees or
contractors shall advertise, market, show, offer for lease or lease all or any
portion of Building No.1 during the first year of the Primary Term of this Lease
and that Tenant shall have the option to lease (the "Expansion Right") all or a
portion of Building No.1 at the Building Complex, on the terms and subject to
the conditions set forth below in (a) and (b).

     (a) If Tenant wishes to lease all or a portion of Building No. 1 during the
first lease year of the Primary Term, it shall give to Landlord written notice
of the exercise of such option, specifying the area to be leased and the date of
occupancy and Landlord shall deliver such space to Tenant on such date free of
all occupants and personal property, in good basic operating condition and
repair (including a roof airtight and free of leaks), broom clean and in
compliance with applicable building, life and safety codes. From and after the
date of such delivery, (i) such space shall be added to the Demised Premises for
the balance of such lease year, (ii) the Base Rent shall be due with respect to
such space at the rate of $4.75 per square foot per annum for such space, and
(iii) Tenant's Proportionate Share shall increase accordingly. Tenant may
exercise its option to add additional portions of Building No. 1 to the Demised
Premises by sending additional written notices of the exercise of its option to
Lease at any time during the first lease year, and the terms of the prior two
sentences shall apply to such additional space.

     (b) In addition to the Expansion Right set forth in Paragraph (a) above,
Tenant shall have the option to lease all of Building No. 1 for a period
beginning on or before the second lease year of the Term and continuing for the
remainder of the Primary Term and any Extended Term with Base Rent for such
space due at the same rate per square foot per annum for 21,189 square feet, as
shall apply to the Initial Premises pursuant to Article 4. If Tenant wishes to
elect such option, it shall do so by giving written to Landlord written notice
of the election of such option on or before March 31, 1999. In such event,
Building No. 1 shall be delivered to Tenant free of all occupants and personal
property, in good basic operating condition and repair (including a roof
airtight and free of leaks), broom clean and in compliance with applicable
building, life and

 
                                      39

safety codes, whereupon such space shall be added to the Demised Premises, and
the provisions of Subsections (4)(a)(i) and (iii) shall apply to such space. If
no such notice is timely given, Tenant shall vacate any portion of Building 
No. 1 occupied by it pursuant to Subparagraph (a) above, on or before March 31,
1999 and all rights of Tenant with respect to the leasing of Building No. 1
pursuant to this Section 32 shall terminate and be of no further force and
effect and Landlord shall be free to advertise, market, show or offer Building
No. 1 for lease, subject to the provisions of Section 33.2.

                      ARTICLE 33 - Additional Provisions

    1.  At any time within six (6) months before the expiration of the Term,
Tenant shall at all reasonable times and upon reasonable advance notice permit
Landlord or its agents to enter the Demised Premises to show the Demised
Premises to others, and to affix to any suitable part of the Building and/or the
Demised Premises, but not so as to interfere unreasonably with any of the signs
or the windows of the Tenant, a notice for letting or selling the Demised
Premises, and to keep the same so affixed without hindrance or molestation by
the Tenant.

    2.  Landlord shall provide Tenant with a notification of vacant space, as
space becomes available, or of space to be vacated, as Landlord becomes aware of
such potential available space, in either the existing Building Complex or in
buildings to be constructed on the Land or on adjacent lots. If Tenant does not
exercise its Expansion Right pursuant to Article 32, then Landlord shall be
required to send a notification under this Section 33.2 as to space in Building
No. 1 only after the initial leasing of such space. If Tenant is interested in
the space, then it must notify Landlord in writing within ten (10) days after
receipt of Landlord's notice that it wants to receive a proposal that would
reflect the terms and conditions of a lease that would be acceptable to the
Landlord at that time. Any rent for such space shall be at fair market rates.
The parties shall either mutually agree to a set of terms and condition within
fifteen (15) days after Tenant has received Landlord's proposal or Landlord
shall commence marketing of the space. Landlord's willingness to notify Tenant
of any vacant space pursuant to this Section 33.2 shall not be construed or
implied to mean that Tenant has either a "Right of First Option" or "Right of
First Refusal" on any space that may become vacant during the Term of Tenant's
Lease, except as set forth in Article 32.

    3.  The covenants and agreement herein contained shall, subject to the
provisions hereof, bind and inure to the benefit of Landlord and its successors
and assigns, and Tenant and its successors and assigns, and no extensions,
modifications or change in the terms of this Lease effected with any successor,
assignee or transferee shall cancel or affect the obligations of the original
parties hereto. No officer, director, shareholder, trustee, or beneficiary of
Landlord or Tenant shall be personally liable hereunder. Each party represents
to the other that the person signing this Lease on its behalf is properly
authorized to do so.

    4.  If any provision of this Lease shall be determined to be invalid or
unenforceable by any court of competent jurisdiction in the Commonwealth of
Massachusetts, then such determination shall not affect any other provision of
this Lease, all of which other provisions shall remain in full force and effect;
and it is the intention of the parties hereto that if any

 
                                      40

provision of this Lease is capable of two constructions, one of which would
render the provision void, and the other of which would render the provision
valid, then the provision shall have the meaning which renders it valid.

    5.  This Lease contains the entire and only agreement between the parties as
to the Demised Premises, and no oral statements or representations or prior
written matter not contained in this instrument shall have any force or effect.
This Lease shall not be modified or canceled except by a writing signed by
Landlord and Tenant.

    6.  This Lease shall be governed by, interpreted and enforced in accordance
with the laws of the Commonwealth of Massachusetts.

    7.  Failure of one party to complain of any act or omission by the other, no
matter how long the same may continue, shall not be deemed to be a waiver of any
rights hereunder. No waiver of any breach of this Lease shall be deemed a
consent to a subsequent breach. All waivers shall be in writing. The consent to
one action given on one occasion shall not be deemed a consent to of the same
action on another occasion. No consent or approval required under this Lease
shall be unreasonably withheld.

    8.  Any and all rights and remedies which either party may have under this
Lease or by operation of law, upon any breach, shall be distinct, separate and
cumulative and shall not be deemed inconsistent with each other; no one of them
whether exercised by the other party or not, shall be deemed to be exclusive of
any other, and any two or more of all such rights and remedies may be exercised
at the same time.

    9.  If at any time a dispute shall arise as to any amount or sum of money to
be paid by one party to the other under the provisions of this Lease, the party
against whom the obligation to pay the money is asserted shall have the right to
make payment "under protest" and such payment shall not be regarded as a
voluntary payment. There shall survive the right on the part of said party to
institute suit for the recovery of such sum, and if it shall be adjudged that
there was no legal obligation on the part of said party to pay such sum or any
part thereof, said party shall be entitled to recover such sum or so much
thereof as it was not legally required to pay under the provisions of this
Lease.

    10. If at any time a dispute shall arise between the parties hereto as to
any work to be performed by either of them under the provisions hereof, the
party against whom the work is asserted may perform such work and pay the cost
thereof "under protest" and the performance of such work shall in no event be
regarded as a voluntary performance. There shall survive the right on the part
of said party to institute suit for the recovery of the costs of such work, and
if it shall be adjudged that there was no legal obligation on the part of said
party to perform the same or any part thereof, said party shall be entitled to
recover the cost of such work or the cost of so much thereof as it was not
legally required to perform under the provisions of this Lease.

    11. Words and phrases used in the singular shall be deemed to include the

                            Attention:  Philip J. Notopoulos

 
     THIS SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT (the
"Agreement") is made as of the _____ day of October, 1998, by and between BAY
STATE FEDERAL SAVINGS BANK, a United States banking corporation ("Lender") and
SeaChange International, Inc. ("Tenant").

                                   RECITALS:

     A.   Lender has made a loan to "Landlord" (defined below) in the amount of
$3,500,000.00 (the "Loan"). The Loan is evidenced by that certain Promissory
Note dated October __, 1998 in the principal amount of the Loan, given by
Landlord to Lender (the "Note").

     B.   The Loan is secured by that certain Mortgage Security Agreement and
Financing Statement (the "Mortgage") dated October __, 1998, given by Landlord
to Lender, which encumbers the fee simple estate of Landlord in certain premises
described in Exhibit A attached hereto (the "Property"), and which secures the
payment of the Note.

     C.   Tenant is the holder of a leasehold estate in a portion of the
Property under and pursuant to the provisions of a certain lease dated May 29,
1998 as amended September 28, 1998 between Maynard Industrial Properties
Associates Trust, as landlord ("Landlord") and Tenant, as tenant (the "Lease"),
notice of which is recorded with the Middlesex (S.D.) Registry of Deeds in Book
____, Page ___.

     D.   Tenant has agreed to subordinate the Lease to the Mortgage and to the
lien thereof and Lender has agreed to grant non-disturbance to Tenant under the
Lease on the terms and conditions hereinafter set forth.

                                  AGREEMENT:

     For good and valuable consideration, Tenant and Lender agree as follows:

     1.   SUBORDINATION. Subject to the provisions of Section 2 and 3 below, the
          -------------
Lease and all of the terms, covenants and provisions thereof and all rights,
remedies and options of Tenant thereunder are and shall at all times continue to
be subject and subordinate in all respects to the terms, covenants and
provisions of the Mortgage and to the lien thereof, including without
limitation, all renewals, increases, modifications, spreaders, consolidations,
replacements and extensions thereof and to all sums secured thereby and advances
made thereunder with the same force and effect as if the Mortgage had been
executed, delivered and recorded prior to the execution and delivery of the
Lease.

                                      -2-

 
     2.  NON-DISTURBANCE. If any action or proceeding is commenced by Lender for
         ---------------    
the foreclosure of the Mortgage or the sale of the Property or to enforce
Lender's rights against Landlord under the Mortgage or the Note or other
obligations secured thereby, Tenant shall not be named as a party therein unless
such joinder shall be required by law, provided, however, such joinder shall
not, nor shall any (i) suit, action, or proceeding upon the Mortgage or the Note
or other obligation secured thereby, (ii) the foreclosure of the Mortgage, (iii)
the enforcement of any rights under the Mortgage, (iv) any other document held
by the Lender, (v) any judicial sale or execution or other sale of the Property
including the premises leased by the Tenant (the "Demised Premises"), (vi) any
deed given in lieu of foreclosure, (vii) the exercise of any other rights given
to the Lender by any other documents, (viii) a matter of law, or (ix) any
default under the Mortgage or the Note or other obligation secured thereby,
result in the termination of the Lease or disturb the Tenant's possession or use
of the Demised Premises demised thereunder, and the sale of the Property in any
such action or proceeding and the exercise by Lender of any of its other rights
under the Note or the Mortgage shall be made subject to all rights of Tenant and
obligations of Landlord under the Lease, provided that at the time of the
commencement of any such action or proceeding or at the time of any such sale or
exercise of any such other rights (a) the term of the Lease shall have commenced
pursuant to the provisions thereof, (b) Tenant shall be in possession of the
premises demised under the Lease, (c) the Lease shall be in full force and
effect and (d) Tenant shall not be in default past applicable grace or cure
periods under any of the terms, covenants or conditions of the Lease or of this
Agreement on Tenant's part to be observed or performed.

     3.  ATTORNMENT AND RECOGNITION. If Lender or any other subsequent purchaser
         -------------------------- 
of the Property shall take possession, collect rent, or become the owner of the
Property

                                      -3-

 
by reason of the foreclosure of the Mortgage or the acceptance of a deed or
assignment in lieu of foreclosure or by reason of any other enforcement of the
Mortgage or otherwise (Lender or such other purchaser being hereinafter referred
as "Purchaser"), and the conditions set forth in Section 2(a)-(d) above have
been met, the Lease shall not be terminated or affected thereby but shall
continue in full force and effect as a direct lease between Purchaser and Tenant
upon all of the terms, covenants and conditions set forth in the Lease and in
that event, Tenant agrees to attorn to Purchaser and Purchaser by virtue of such
acquisition of the Property, possession or collection of rent, shall be deemed
to have agreed to accept such attornment, provided, however, that Purchaser
shall not be (a) liable for the failure of any prior landlord (any such prior
landlord, including Landlord and any successor landlord, being hereinafter
referred to as a "Prior Landlord") to perform any of its obligations under the
Lease which have accrued prior to the date on which Purchaser shall become the
owner of the Property, provided that the foregoing shall not limit Purchaser's
obligations under the Lease to correct any conditions that (i) existed as of the
date Purchaser shall become the owner of the Property and (ii) violate
Purchaser's obligations as landlord under the Lease; provided further, however,
that Purchaser shall have received written notice of such omissions, conditions
or violations and has had a reasonable opportunity to cure the same, all
pursuant to the terms and conditions of the Lease, (b) subject to any offsets,
defenses, abatements or counterclaims which shall have accrued in favor of
Tenant against any Prior Landlord prior to the date upon which Purchaser shall
become the owner of the Property, (c) liable for the return of rental security
deposits, if any, paid by Tenant to any Prior Landlord in accordance with the
Lease unless such sums are actually received by Purchaser, (d) bound by any
payment of rents, additional rents or other sums which Tenant may have paid more
than one (1) month in advance to any Prior Landlord unless (i) such sums are
actually received by

                                      -4-

 
Purchaser or (ii) such prepayment shall have been expressly approved of by
Purchaser or (e) bound by any agreement terminating (unless pursuant to a
termination right under the Lease) or amending or modifying the rent, term,
commencement date or other material term of the Lease, or by any voluntary
surrender of the premises demised under the Lease, made without Lender's or
Purchaser's prior written consent prior to the time Purchaser succeeded to
Landlord's interest. In the event that any liability of Purchaser does arise
pursuant to this Agreement, such liability shall be limited and restricted to
Purchaser's interest in the Property and shall in no event exceed such interest.

     Lender agrees that, in the event of damage or destruction to the Premises
by casualty, Lender will not unreasonably withhold its consent to a request by
Landlord to advance insurance proceeds for restoration of the Premises provided,
however, the following conditions are met:

      (a) Landlord shall not be in default past applicable notice and grace
          periods under the Note or the Mortgage or any documents securing or
          given in connection with the Note (the "Loan Documents");

      (b) Tenant shall not be in default under the Lease beyond applicable
          notice and grace periods;

      (c) The insurance proceeds are in the opinion of Lender sufficient to
          restore the property or, if the proceeds are not sufficient, Landlord
          has deposited with Lender the amount of any such insufficiency;

      (d) The Premises may be restored as a matter of right under applicable law
          and Landlord has secured all permits therefore;

                                      -5-

 
     (e)  Tenant shall not be entitled to terminate the Lease on account of said
          casualty, or if such termination right exists, Tenant has waived the
          same;

     (f)  The insurance proceeds will be held by Lender and will be advanced
          under Lender's customary construction loan procedures; and

     (g)  The damage or destruction does not occur within the last two years of
          the term of the Lease unless the Lease has been extended.

     Lender acknowledges and agrees that all trade fixtures, equipment and other
property owned by the Tenant located or installed in or on the Demised Premises,
regardless of the manner or mode of attachment, shall be and remain the property
of Tenant and may be removed by Tenant at any time according to the provisions
of Articles 9, 16, and 27 of the Lease

     4.   NOTICE TO TENANT. After notice is given to Tenant by Lender that the
          ----------------
Landlord is in default under the Note and the Mortgage and that the rentals
under the Lease should be paid to Lender pursuant to the terms of the assignment
of leases and rents executed and delivered by Landlord to Lender in connection
therewith, Tenant shall thereafter pay to Lender or as directed by the Lender,
all rentals and all other monies due or to become due to Landlord under the
Lease and Landlord hereby expressly authorizes Tenant to make such payments to
Lender and hereby releases and discharges Tenant from any liability to Landlord
on account of any such payments.

     5.   NOTICE TO LENDER AND RIGHT TO CURE. Tenant shall notify Lender of any
          ----------------------------------                                    
default by Landlord under the Lease and agrees that, notwithstanding any
provisions of the Lease to the contrary, no notice of cancellation thereof or of
an abatement shall be effective unless Lender shall have received notice of
default giving rise to such cancellation or abatement and shall have failed
within sixty (60) days after receipt of such notice to cure such default, or if

                                      -6-

 
such default cannot be cured within sixty (60) days, shall have failed within
sixty (60) days after receipt of such notice to commence and thereafter
diligently pursue any action necessary to cure such default, but in any event
such cure shall be effected within 120 days of receipt of said notice.
Notwithstanding the foregoing, Lender shall have no obligation to cure any such
default.

     6.  NOTICES. All notices or other written communications hereunder shall be
