                    deemed ready for occupancy on the first day as of which
                    LESSOR'S work as delineated on Exhibit "B", attached hereto
                    and made a part hereof, has been completed except for items
                    of work (and, if applicable, adjustment and fixtures) which
                    can be completed after occupancy has been taken, without
                    causing undue interference with LESSEE'S use of the Premises
                    (i.e., so-called "punch list" items) and LESSEE has been
                    given notice thereof. LESSOR shall complete as soon as

                    its business prior to the Commencement Date as determined
                    herein, such date of occupancy shall, for all intents and
                    purposes of this Lease, be the Commencement Date.

                    Landlord and Tenant agree to execute a Supplemental
                    Agreement setting forth the actual Occupancy and Term Dates,
                    once the same have been established.

         conditions and provisions of this Lease, the Premises, but reserving
         and excepting to Landlord the use of the exterior walls, the roof and
         the right to install, maintain, use, repair and replace pipes, ducts,
         conduits, wires and appurtenant fixtures leading through the Premises
         and serving other parts of the Building or Lot in locations which will
         not materially interfere with Tenant's use thereof. Exhibit A is
         intended only to show the location of the Premises in relation to the
         Building and/or Lot and the initial size of such Building and Lot, and
         other data thereon is to be disregarded and in no event deemed or
         construed to be a representation that the Building or buildings,
         parking areas or other improvements shown thereon will be constructed
         and/or maintained as indicated thereon, or that additions to, or
         reductions from, the Building or Lot may not be made by the Landlord
         during the Term of this Lease, but rather the Landlord shall have the
         right to do so provided that the same does not materially interfere
         with Tenant's access to and Use of the Premises, and any such addition
         or reduction shall take effect upon Landlord's giving notice to Tenant
         to that effect. Landlord reserves the right to construct or sell any
         free-standing buildings on any portion of the Lot.

3.       TERM. The Term of this Lease shall commence upon the Commencement Date,
         which shall be the date set forth in the Basic Data, subject to
         Paragraph 23 concerning unavoidable delays. The Premises shall be
         deemed ready for occupancy under the terms of this Lease and Landlord's
         obligation to deliver the Premises to Tenant as of the Commencement
         Date shall be deemed fulfilled if Landlord's construction within the
         Premises as required herein is substantially completed with the
         exception of minor items which can be fully completed within thirty
         (30) days without material interference with Tenant's occupancy of the
         Premises. The use by Tenant of the Premises for business shall be
         deemed conclusive that the Premises were substantially completed and
         that Tenant accepted delivery of the Premises as substantially
         completed. Landlord's construction and other work shall be as set forth
         in Exhibit B hereto.


<PAGE>


3A.      OPTION TO EXTEND. Provided that (i) Tenant has not assigned the Lease,
         and (ii) the Premises are not then subject to a sublease (whether the
         term of the sublease has commenced or is to be commenced thereafter)
         and Tenant will not be exercising the rights hereinafter set forth with
         the intent of assigning the Lease or subleasing any portion of the
         Premises, then Tenant has the right to extend the Lease Term for one
         (1) five (5) year period ("Extension Period") at a Base Rent equal to
         the then Current Market Rate, but in no event shall such rental be less
         than the last annual rent paid by Tenant, and otherwise on the same
         terms and conditions as this Lease, except that there shall be no
         further rights to extend the Lease Term. Tenant shall exercise this
         option by written notice to Landlord not more than nine (9) months nor
         less than six (6) months before the expiration of the Lease Term.
         Tenant's exercise of this option shall be effective only if, at the
         time of notice and upon the effective date of the Extension Period,
         there is no Event of Default.

         Thereupon, this Lease shall be deemed extended for an additional period
         of five (5) years, upon all of the same terms and conditions of this
         Lease and any Amendments made hereto with the exception of the annual
         rent stipulated hereinabove.

         Tenant's exercise of this renewal option shall be null and void unless
         Landlord receives (i) simultaneously with the notice of exercise and
         (ii) thirty (30) days before the commencement of the Renewal Term,
         Tenant's certified financial statements for the immediately preceding
         three (3) year period. In the event the credit worthiness of Tenant is
         not sufficient in Landlord's sole discretion to assure the future
         performance of Tenant's obligations under the Lease during the Renewal
         Term, Landlord may nullify Tenant's exercise of this renewal option.

4.       SECURITY DEPOSIT. - INTENTIONALLY OMITTED.

5.       ANNUAL RENT. Tenant hereby covenants and agrees to pay to Landlord, at
         the place to which notices to Landlord are required to be sent or such
         other person or place as Landlord may from time to time designate, as
         Annual Rent for the Premises in lawful money of the United States,
         without demand, setoff or deduction, during the Term of this Lease, the
         sum set forth in Basic Data, payable in equal monthly installments as
         set forth there, in advance on the first day of each and every calendar
         month during said Term. Annual Rent for any fraction of a month at the
         commencement or expiration of said Term shall be prorated on a per diem
         basis.

6.       ADDITIONAL RENT.

         (a) TAXES. Tenant covenants and agrees to pay, as Additional Rent, with
         respect to each calendar or other tax year beginning or ending during
         the Term hereof, an amount equal to Tenant's Pro Rata Share, as set
         forth in the Basic Data, of the real estate taxes (including
         betterments and other special


<PAGE>


         assessments) allocated to the Building and Lot for such tax year. If
         there shall be more than one taxing authority, the real estate taxes
         for any period shall be the sum of the real estate taxes for said
         period attributable to each taxing authority. Tenant's Pro Rata Share
         of the real estate taxes shall be adjusted for and with respect to any
         partial tax years on a per diem basis. The expression "real estate
         taxes" shall include all general and special assessments, so-called,
         rent taxes and other governmental charges which may be charged,
         assessed or imposed upon the Building and Lot or Landlord. If at any
         time during the term hereof the present system of ad valorem taxation
         of real property shall be changed so that in lieu of the ad valorem tax
         on real property in whole or in part, or in addition thereto, there
         shall be assessed on Landlord a capital levy or other tax on, but not
         limited to, the Annual Rent and/or any Additional Rent ("Gross Rents")
         received with respect to the Building and Lot, or a federal, state,
         county, municipal or other local income, franchise, excise or similar
         tax, assessment, levy or charge (distinct from any method of taxation
         prevailing at the commencement of the Term hereof) measured by or
         based, in whole or in part, upon any such Gross Rents, then any and all
         of such taxes, assessments, levies or charges, to the extent that the
         same would be payable if the Building and Lot were the only property of
         Landlord subject to them, and if the income from the Building and Lot
         were the only taxable income of Landlord during the year in question,
         shall be deemed to be included within the term "real estate taxes".
         Notwithstanding anything to the contrary contained herein, "real estate
         taxes" shall not include Landlord's Federal or State income taxes as
         presently imposed.

         (b) TAX PAYMENTS. Payment of Tenant's Pro Rata Share of the real estate
         taxes allocated to the Building and Lot shall be paid, as Additional
         Rent, monthly, and at the times and in the fashion herein provided for
         the payment of Annual Rent. For an initial period from the Commencement
         Date until the end of the first full tax year in which the Building
         and/or Lot containing the Premises shall be assessed as a completed
         improvement, as distinguished from inprocess construction ("the full
         assessment year"), the amount so to be paid shall be the initial
         monthly payment reasonably fixed by Landlord on or about the
         Commencement Date. Promptly after the determination by any taxing
         authority of real estate taxes upon the Building and Lot for each tax
         year, Landlord shall make a determination of the Tenant's Pro Rata
         Share of the real estate taxes and if the aforesaid payments
         theretofore made for such tax year by Tenant exceed Tenant's Pro Rata
         Share of the real estate taxes such overpayment shall be credited
         against the payments thereafter to be made by Tenant pursuant to this
         paragraph; and if the real estate taxes for such tax year are greater
         than such payments theretofore made on account for such tax year,
         Tenant shall pay such deficiency to Landlord within ten (10) days of
         demand therefor. Copies of tax bills submitted by Landlord with any
         such statement shall be conclusive evidence of the amount of real
         estate taxes charged, assessed or imposed. After the full assessment
         year, the initial monthly payment on account of the Tenant's Pro Rata
         Share of the real estate taxes shall be replaced each year by a payment
         which is one-twelfth (1-12th) of the Tenant's Pro Rata Share of the
         real estate taxes for the immediately preceding tax year. An equitable
         adjustment shall be made in the event of any change in the method or
         system of taxation from that which is now applicable, including without
         limitation any change in the dates and periods for which such taxes
         were levied. Tenant shall pay all taxes upon its signs and other
         property in or upon the Premises and Tenant covenants and agrees to pay
         promptly when due all municipal, county, state and federal taxes
         assessed against Tenant's leasehold interest and Tenant's fixtures,
         furnishing, equipment, stock-in-trade, and other personal property of
         any kind owned, installed or existing in the Premises. For the purpose
         of this paragraph such taxes shall not be included within real estate
         taxes upon the Building and Lot.

         (c) COMMON AREAS. Tenant and its officers, employees, agents, customers
         and invitees shall have the right, in common with Landlord and all
         others to whom Landlord may from time to time grant rights, to use the
         common areas of the Building and Lot for their intended purposes
         subject to such reasonable rules and regulations as Landlord may from
         time to time impose, including the designation of specific areas in
         which cars owned or operated by Tenant, its officers, employees and
         agents must be parked. Tenant agrees after notice thereof to abide by
         such rules and regulations and to cause its officers, employees,
         agents, customers and invitees to conform thereto. Landlord shall at
         all times have full control, management and direction of the common
         areas and the right to put the common areas to such use as the Landlord
         may determine in its sole discretion. Landlord shall have the right at
         any time and from time to time to change the layout of the common areas
         including, but without limitation, the right to add to or subtract from
         their shape and size and to alter their location; provided, however,
         Landlord shall always maintain such amount of parking in the common
         areas as may be required by local zoning law or ordinance at the time
         of such parking area's original construction, and further provided the
         same does not materially interfere with Tenant's access to and Use of
         the Premises.

         (d) CHARGES FOR COMMON AREAS. Tenant shall pay its Pro Rata Share of
         the Common Areas Maintenance Costs during the Term of this Lease as
         Additional Rent and in the manner hereafter provided. "Common Areas
         Maintenance Costs" as used herein shall mean the total cost and
         expenses incurred by Landlord, its agents, contractors and/or designees
         for operating, maintaining, insuring (or, if Landlord elects to self
         insure, an amount equal to the cost of insurance if it were to be
         provided by a third party of Landlord's choosing), managing, repairing
         and/or replacing all or any part of the common areas and any
         installations therein, thereon, thereunder or thereover. Payment on
         account of Tenant's Pro Rata Share of the Common Areas Maintenance
         Costs shall be paid as Additional Rent, monthly, and at the times and
         in the fashion herein provided for the payment of Annual Rent based
         initially on Landlord's reasonable estimate. Promptly after the end of
         the partial calendar year during which the Term begins and promptly
         after the end of each year thereafter, Landlord shall make a
         determination of Tenant's Pro Rata Share of the Common Areas
         Maintenance Costs. If the aforesaid payments theretofore made for such
         period by Tenant exceed Tenant's Pro Rata Share, such overpayment shall
         be credited against the payments thereafter to be made by Tenant
         pursuant to this paragraph; and if Tenant's Pro Rata Share is greater
         than such payments theretofore made on account for such period, Tenant
         shall pay such deficiency to Landlord within ten (10) days of demand
         therefore. The initial monthly payment on account of the Common Areas
         Maintenance Costs shall be replaced after Landlord's determination of
         Tenant's Pro Rata Share thereof for the preceding accounting period by
         a payment which is one-twelfth (1/12th) of Tenant's actual Pro Rata
         Share thereof for the immediately preceding accounting period, with
         adjustments as appropriate where such preceding period is less than a
         full twelve-month period. Appropriate adjustments shall be made for any
         partial month at the commencement of the Term and for any partial month
         or year at the end of the Term.

7.       UTILITIES. Tenant agrees to pay or cause to be paid, as Additional
         Rent, directly to the authority or party charged with the collection
         thereof, all charges for gas, electricity, light, heat, power, water,
         sewerage, telephone or other service used, rendered or supplied to or
         for the Tenant upon or in connection with the Premises throughout the
         Term of this Lease, and to indemnify Landlord and save it harmless
         against any liability or damages on such account. Tenant shall also at
         its sole cost and expense procure any and all necessary permits,
         licenses or other authorizations required for the lawful and proper
         maintenance and use upon the Premises of wires, pipes, conduits, tubes
         and other equipment and appliances for use in supplying any such
         services to and upon the Premises except such permits, licenses and
         authorizations which shall be required in connection with original
         construction of the Premises, which shall be obtained by Landlord. It
         is understood and agreed that Landlord shall be under no obligation to
         furnish any utilities to the Premises and shall not be liable for any
         interruption or failure in the supply of any such utilities to the
         Premises. If a charge shall be made from time to time by the public
         authority having jurisdiction of the Premises for the use of the
         sanitary sewer system, Tenant shall pay the share thereof equitably
         apportionable to the Premises. Tenant shall also pay for any sprinkler
         standby service charge equitably apportionable to the Premises. If the
         Premises are not separately metered, Tenant shall pay to Landlord, as
         billed and as additional Rent, its share of water and/or sewer bills.
         In case any such water and sewer charges are not paid by Tenant at the
         time when the same are payable, if to municipal officials, Landlord may
         nevertheless pay the same to such officials and charge Tenant the cost
         thereof, which charge shall become payable on the first day of the
         following month as Additional Rent.

8.       TENANT'S USE OF PREMISES AND MISCELLANEOUS COVENANTS. During the Term
         of this Lease Tenant shall use the Premises solely for the purposes
         listed in the Basic Data. Tenant agrees that it will not use, or permit
         or suffer the use of, the Premises or any part thereof for any other
         business or purpose. Tenant shall use and occupy the Premises in a
         careful, safe and proper manner and shall keep the Premises in a clean
         and safe condition in accordance with all applicable laws, ordinances
         and government regulations. Tenant agrees that it will not do or suffer
         to be done, or keep or suffer to be kept, anything in, upon or about
         the Premises which will contravene Landlord's policies insuring against
         loss or damage by fire or other hazards, or which will prevent Landlord
         from procuring such policies from companies acceptable to Landlord.

         During the Term of this Lease, Tenant further covenants and agrees as
         follows:

         (a) Not to use the Premises for any use involving the emission of
         objectionable odors, fumes, noise or vibration, or, except to the
         extent previously consented to by Landlord in writing, involving the
         use, storage or disposition of toxic or hazardous substances or
         materials. Tenant covenants and agrees that it shall advise Landlord in
         writing of any materials or substances it deals with in any way on the
         Premises that may be deemed to be hazardous or toxic prior to such
         substances or materials being brought upon the Premises or Lot. In any
         event, Tenant shall strictly comply with all state, federal and
         municipal laws, regulations, guidelines and ordinances concerning the
         use, storage, handling and disposition of any substance or material
         that is or may be deemed to be toxic or hazardous and Tenant


<PAGE>


         agrees to indemnify Landlord against any liability, including attorneys
         fees and costs, in connection therewith. At Landlord's request, Tenant
         shall provide Landlord with reasonable assurances that Tenant can and
         will comply with the foregoing and, if Landlord so requests, Tenant
         shall obtain insurance of such type and in such amount as Landlord may
         reasonably specify, such policy to name Landlord as an insured party
         and be obtained at Tenant's sole cost prior to such substances or
         materials being brought upon the Premises or Lot. Any such policy shall
         provide that it may not be canceled or amended without thirty (30) days
         prior notice to Landlord, and shall be issued by a company or companies
         reasonably satisfactory to Landlord. Failure of Tenant to provide
         Landlord with such reasonable assurances or evidence of any reasonably
         requested insurance in connection with the bringing of such materials
         or substances upon the Premises or Lot shall be reasonable cause for
         Landlord to prohibit such substances or materials from being brought
         upon the Premises or Lot or, at Landlord's election, a default under
         this Lease.

         (b) Not to permit the use of the Premises for trucking of a character
         or volume greater than that customarily employed by other occupants of
         the Building or Lot or any use permitted under this Lease for which
         trucking of such character and volume is customary.

         (c) Not to place on the Premises or Building any placard or sign of
         advertising that the Premises or any part thereof may be sublet, nor to
         place any other sign or placard on the Premises or Building which is
         visible from the exterior of the Premises or Building without the
         written consent of Landlord.

         (d) Not to injure, overload, deface or permit to be injured,
         overloaded, or defaced, the Premises or Building, and not to permit any
         holes to be made in the exterior of the building; and not to make,
         allow or suffer any waste or any unlawful, improper or offensive use of
         the Premises that shall be injurious to any person or property or
         invalidate any insurance on the Premises, Building or Lot or increase
         the premium thereof.

         (e) To conform to and comply with all state and municipal laws and with
         all requirements of any public body or officers having jurisdiction of
         the Premises and with the requirements or regulations of any Board of
         Fire Underwriters or insurance company insuring the Premises at the
         time with respect to the care, maintenance, use and nonstructural
         alteration of the Premises, all at Tenant's sole expense.

9.       REPAIRS TO AND MAINTENANCE OF PREMISES BY TENANT. Tenant shall keep the
         Premises, including without limitation, both the inside and outside of
         all doors and windows therein, in the same order and repair as they are
         in on the Commencement Date, reasonable wear and tear and damage by
         fire or other casualty normally insured under a so-called "extended
         coverage endorsement" only excepted; and to keep all fixtures and
         equipment on the Premises including, without limitation, all heating,
         plumbing, electrical, air-conditioning, ventilation and mechanical
         fixtures and equipment serving only the Premises in the same order and
         repair as they are in on the Commencement Date, ordinary wear and tear,
         damage by fire or other casualty normally insured under an "extended
         coverage endorsement" only excepted. Tenant shall, at it sole cost and
         expense, during the entire Term of this Lease, maintain in force a
         service contract providing for the repair and annual service and
         maintenance of all heating, ventilating and air conditioning equipment
         serving the Premises, or hire a qualified person to perform such
         services on at least a semi-annual basis, or more often if needed,
         provided such person is reasonably acceptable to Landlord. Tenant shall
         make all repairs and replacements and do all other work necessary for
         the foregoing purposes. It is further agreed that the exception of
         reasonable wear and tear shall not apply so as to permit Tenant to keep
         the Premises in anything less than suitable, tenantlike, efficient and
         usable condition considering the nature of the

<PAGE>


         Premises and the use reasonably made thereof, or in less than good and
         tenantlike repair, and that except in case of fire or other casualty
         normally insured under an "extended coverage endorsement" there is no
         exception to the rule that all glass must be kept good and whole by
         Tenant. Tenant shall also be responsible for the cost of all repairs to
         the Building (including, without limitation, the structure and roof
         thereon and common areas therein) and the Lot if the same are
         occasioned by Tenant's or its employees', agents' or invitees' improper
         or negligent use thereof.

10.      SUBLETTING AND ASSIGNMENT.

         (a) Tenant covenants and agrees not to assign, sell, mortgage, pledge
         or in any manner transfer this Lease

         or any interest therein or sublet the Premises or any part thereof, or
         grant any concession or license or otherwise permit occupancy of all or
         any part thereof by another person or entity without the prior written
         consent of Landlord, which consent shall not be unreasonably withheld
         provided all the provisions of this Paragraph 10 are complied with and
         subject to Landlord's right to terminate this Lease as set forth in
         this Paragraph 10. Any such consent by Landlord shall be held to apply
         only to the specific transaction thereby authorized. Such consent shall
         not be construed as a waiver of the obligation of Tenant to obtain from
         Landlord consent to any other or subsequent assignment or subletting
         period. The collection of rent by Landlord from any assignee, subtenant
         or other occupant shall not be deemed an acceptance of the assignee,
         subtenant or occupant as tenant or release of Tenant from its
         obligation under this Lease.

         (b) Notwithstanding the provisions of Paragraph 10(a), above, any
         proposed assignee or sublessee submitted to the Landlord for approval
         must have the same or greater financial strength as Tenant and if such
         is not the case, Landlord's withholding of consent shall be reasonable.
         If Tenant shall request permission to assign this Lease or sublet the
         Premises or any part thereof Tenant shall, together with such request
         for consent thereto, inform Landlord of the rental and any other
         amounts to be paid by such assignee or subtenant in connection with
         such subletting or assignment regardless of the nomenclature such
         payment may take, the term of any subletting, and any financial
         information required or requested by Landlord to make the determination
         required by the first sentence of this Paragraph 10(b). Landlord shall
         have the right to terminate this Lease in lieu of consenting or
         reasonably withholding its consent to the proposed subletting or
         assignment, provided that Landlord shall exercise such right within
         forty-five (45) days of its receipt of Tenant's request for such
         consent and provided, further, that Tenant shall have the right to
         withdraw its request for such consent within fifteen (15) days after
         its receipt of such notice from Landlord, in which event such notice of
         termination shall become null and void. If this Lease shall be
         terminated pursuant to the provisions of the immediately preceding
         sentence, such termination shall become effective upon the last day of
         the calendar month next following Landlord's giving said notice of
         termination.

         (c) If Landlord consents in writing to an assignment or subletting,
         such consent shall be deemed conditioned upon Tenant's compliance with
         the following provisions and the failure to so comply shall be deemed
         to give Landlord reasonable cause for withholding or withdrawing its
         consent:

                  (1)  The assignment or subletting must be,
                  respectively, of all Tenant's leasehold interest or of the
                  entire Premises and, in the case of an assignment, shall also
                  transfer to the assignee all of Tenant's rights in and
                  interests under this Lease, including but without limitation,
                  the Security Deposit hereunder.

                  (2)  At the time of such assignment or subletting, this Lease
                  must be in full force and effect without any breach or default
                  hereunder on the part of Tenant.

<PAGE>


                  (3)  The assignee or sublessee shall assume, by written
                  recordable instrument, in form and content satisfactory to
                  Landlord, the due performance of all Tenant's obligations
                  under this Lease, including any accrued obligations at the
                  time of the assignment or subletting.

                  (4)  A copy of the assignment or sublease and the original
                  assumption agreement (both in form and content satisfactory to
                  Landlord) fully executed and acknowledged by the assignee or
                  sublessee, together with a certified copy of a properly
                  executed corporate resolution authorizing such assumption
                  agreement, shall be received by Landlord within ten (10) days
                  from the effective date of such assignment or subletting.

                  (5)  Such assignment or subletting shall be upon and subject
                  to all the provisions, terms, covenants and conditions of this
                  Lease including but without limitation the use permitted
                  hereby and Tenant (and any assignee(s), subtenant(s) and
                  guarantor(s) of this Lease) shall continue to be and remain
                  primarily and unconditionally liable hereunder.

                  (6)  Tenant shall reimburse Landlord for Landlord's attorneys'
                  fees for examination of and/or preparation of any documents in
                  connection with such assignment or subletting.

                  (7)  Any rent, sum or other consideration to be paid or given
                  in connection with such sublease or assignment, either
                  initially or over time, in excess of the Annual Rent and/or
                  Additional Rent and/or other charges to be paid under this
                  Lease shall be paid directly to Landlord as if such amount
                  were originally called for by the terms of this Lease as
                  Additional Rent and Tenant shall be liable to Landlord for all
                  such amounts.

         (d) Subject to the enumerated conditions of the preceding Paragraph
         10(c), Landlord hereby consents to the assignment or subletting of the
         entire Premises to a corporation which is a wholly owned subsidiary of
         Tenant, or to a company that owns one hundred percent (100%) of all the
         issued and outstanding capital stock of Tenant, or in the event of a
         merger, provided that (i) Landlord is given at least ten (10) days
         prior written notice of such occurrence, (ii) the occurrence will not
         impair the reputation of the Building, and (iii) the occurrence will
         not materially increase the risk of Tenant's default. Notwithstanding
         any such assignment or subletting as provided in this Paragraph 10(d),
         such assignment or subletting shall be upon and subject to all the
         provisions, (except for Landlord's right to terminate as provided in
         subsection (b) above) terms, covenants and conditions of this Lease and
         Tenant (and any assignee(s), subtenant(s) and guarantor(s) of this
         Lease) shall continue to be and remain liable hereunder.

11.      ALTERATIONS. Tenant shall not modify the leasehold improvements or make
         any alterations to the Premises with the exception of non-structural
         alterations costing less than $10,000.00, without first obtaining
         Landlord's prior written approval of such modifications and
         alterations; provided, however, Landlord shall not unreasonably
         withhold its consent to nonstructural alterations of the Premises.

12.      TRASH REMOVAL. Tenant shall be responsible for the removal of its own
         trash, rubbish, garbage and refuse removal, at its sole cost and
         expense. Tenant shall not permit the accumulation of rubbish, trash,
         garbage and other refuse in and around the Premises. No rubbish, trash,
         garbage or other refuse shall be burned by Tenant in the Premises or
         elsewhere in the Building or Lot and all of the same shall be kept in
         suitable containers in the interior of the Premises (or in locations
         outside the Premises as Landlord may permit by notice in writing) until
         the same is picked up from the Premises and the Building and/or Lot.
         The removal agency selected by Tenant shall be subject to Landlord's
         reasonable approval. In the event Tenant fails to remove any
         accumulation of rubbish within twenty-four (24) hours after notice from
         Landlord to remove the same, Landlord shall have the right (but not the
         obligation) to remove the same, in which event the cost thereof shall
         be paid by Tenant as Additional Rent immediately upon demand.


<PAGE>




13.      MECHANIC'S LIENS. Tenant will not permit to be created or to remain
         undischarged any lien, encumbrance or charge arising out of any work of
         any contractor, mechanic, laborer or materialman or any mortgage,
         conditional sale, security agreement or chattel mortgage, or otherwise
         which might be or become a lien or encumbrance or charge upon the
         Premises or any part thereof or the income therefrom, and Tenant will
         not suffer any other matter or thing whereby the estate, rights and
         interest of Landlord in the Premises or any part thereof might be
         impaired. If any lien on account of an alleged debt of Tenant or any
         notice of contract by a party engaged by Tenant or Tenant's contractor
         to work on the Premises shall be filed against the Premises, Building
         or Lot, or any part thereof, within ten (10) days after notice of the
         filing thereof Tenant shall cause the same to be discharged of record
         by payment or bond. If Tenant shall fail to cause such lien to be
         discharged within the period aforesaid then, in addition to any other
         right or remedy, Landlord may, but shall not be obligated to, discharge
         the same either by paying the amounts claimed to be due or by procuring
         the discharge of such lien by deposit or by bonding proceedings, and in
         any such event Landlord shall be entitled to compel the prosecution of
         an action for the foreclosure of such lien by the lienor or to pay the
         amount of the judgment in favor of the lienor with interest, costs and
         allowances. Any amount so paid by Landlord and all costs and expenses,
         including without limitation reasonable attorneys fees, incurred by
         Landlord in connection therewith, together with interest thereon at the
         rate specified in Paragraph 19(d) from the respective dates of
         Landlord's making of the payment or incurring of the cost and expense,
         shall constitute Additional Rent payable by Tenant under this Lease and
         shall be paid by Tenant to Landlord immediately upon demand.

14.      ACCESS TO PREMISES. Landlord shall have free access to the Premises
         upon reasonable notice to the Tenant and without interference with
         Tenant's Use of the Premises, at all reasonable time (and in case of
         emergency at any time) for the purpose of examining the same or making
         such repairs, alterations, additions or improvements to the Premises,
         or the Building of which the Premises are a part, that Landlord may
         deem necessary or which Tenant has failed to do (but nothing in this
         Paragraph shall obligate Landlord to make any such repairs,
         alterations, additions or improvements) and also for the purpose of
         exhibiting the Premises and putting up notices "To Rent," during the
         last six (6) months of the original or extended term, as the case may
         be, or "For Sale", which notices shall not be removed, obliterated or
         hidden by Tenant. No forcible entry shall be made by Landlord unless
         such entry shall be reasonably necessary to prevent injury, loss or
         damage to persons or property, and Landlord shall repair any damage to
         property occasioned thereby. Landlord shall repair any damage to
         property of Tenant or anyone claiming under Tenant caused by or
         resulting from Landlord's making any such repairs, alterations,
         additions or improvements except only such damage as shall result from
         the entry to the Premises and/or the making of such repairs,
         alterations, additions or improvements which Landlord shall make as a
         result of an emergency or the default, negligence, fault or willful
         misconduct of Tenant or anyone claiming under or through Tenant. No
         action of Landlord pursuant to this Paragraph shall be deemed an
         eviction or disturbance of Tenant nor shall Tenant be allowed any
         abatement of rent or damages for any injury or inconvenience occasioned
         thereby.

15.      REMOVAL OF IMPROVEMENTS. Except as otherwise hereinafter provided, all
         trade fixtures, furniture, furnishings and signs installed in the
         Premises by Tenant and paid for by it shall remain the property of
         Tenant and shall be removed by Tenant upon the expiration of the Term
         of this Lease or its earlier termination, provided (a) that any of such
         items as are affixed to the Premises and require severance may be
         removed only if Tenant shall repair any damage caused by such removal,
         (b) that Tenant shall have fully performed all of the covenants and
         agreements to be performed by it under the provisions of this Lease,
         and (c) that Tenant shall comply with the last sentence of this
         Paragraph. If the Tenant fails to remove such items from the Premises
         prior to the expiration of this Lease or earlier termination hereof,
         all such trade fixtures, furniture, furnishings and signs shall become
         the property of the Landlord. All lighting fixtures, heating and
         cooling equipment and all other installations, alterations, additions
         and improvements to the Premises shall be and remain the property of
         Landlord on the ending of the Term hereof or any earlier termination of
         this Lease and shall not be removed from the Premises.

16.      TENANT'S INSURANCE OBLIGATION. Tenant shall carry public liability
         insurance in a company or companies licensed to do business in the
         state in which the Premises are located and reasonably approved by
         Landlord. Said insurance shall be in minimum amounts reasonably
         required by Landlord from time to time by notice to Tenant and shall
         name Landlord as an additional insured, as its interests may appear,
         and Tenant shall provide Landlord with evidence, when requested, that
         such insurance is in full force and effect. Tenant shall carry property
         damage insurance for all of its equipment and for all leasehold
         improvements above the building standard which are made by Landlord or
         Tenant in and to the Premises, which policies shall name Landlord as an
         additional insured. If required by Landlord, receipts evidencing
         payment for said insurance shall be delivered to Landlord at least
         annually by Tenant and each policy shall contain an endorsement that
         will prohibit its cancellation or amendment prior to the expiration of
         thirty (30) days after notice of such proposed cancellation or
         amendment to Landlord. Tenant shall carry insurance in the initial
         amounts listed in the Basic Data and shall provide Landlord with
         certificates of such Tenant Insurance Requirements on or prior to the
         Commencement Date.

17.      REPAIRS BY LANDLORD. Landlord agrees to make all necessary repairs or
         alterations to the foundation, roof and structural parts of the
         exterior walls of the Premises. Notwithstanding the foregoing, if any
         of said repairs or alterations shall be made necessary by reason of
         repairs, installations, alterations, additions or improvements made by
         Tenant or anyone claiming under or through Tenant, by reason of the
         default, negligence, fault, or willful misconduct of such party, or by
         reason of a default in the performance or observance of any agreements,
         conditions or other provisions on the part of Tenant to be performed or
         observed, or by reason of any special use to which the Premises may be
         put, Tenant shall be liable for the cost of all such repairs or
         alterations as may be necessary. Landlord shall not be deemed to have
         committed a breach of any obligation to make repairs or alterations or
         perform any other act unless (a) it shall have made such repairs or
         alterations or performed such other act negligently, or (b) it shall
         have received notice from Tenant designating the particular repairs or
         alterations needed or the other act of which there has been failure of
         performance and Landlord shall have failed to make such repairs or
         alterations or performed such other act within a reasonable time after
         the receipt of such notice; and in the latter event Landlord's
         liability shall be limited to the cost of making such repairs or
         alterations or performing such other act. As used in this Lease, the
         expression "exterior walls of the Premises" does not include glass,
         windows, doors or door frames, or window sashes or frames. Landlord
         shall make all necessary repairs to the common areas and shall maintain
         such common areas (except sidewalks abutting the Premises) reasonably
         clear of litter and shall perform snow handling to the extent required
         for business operations of the Building. The provisions of this
         Paragraph shall not apply in the case of damage or destruction by fire
         or other casualty or by eminent domain, in which events the obligations
         of Landlord shall be controlled by Paragraph 18 hereof.

18. DAMAGE OR DESTRUCTION BY EMINENT DOMAIN, FIRE OR CASUALTY.

         (a) In the event that the Premises and/or Building and/or Lot, or any
         material part thereof, shall be taken by any public authority or for
         any public use, or shall be destroyed or damaged by fire or casualty,
         or by the action of any public authority, then this Lease may be
         terminated at the election of Landlord. Such election shall be made by
         the giving of written notice by Landlord to Tenant within thirty (30)
         days after the right of election accrues. If by such taking Tenant is
         deprived of the use of more than thirty percent (30%) of the Square
         Footage of the Premises, or if by such fire or other casualty more than
         fifty percent (50%) of the Square Footage of the Premises shall be
         rendered untenable, and if Landlord does not within a reasonable time
         after notice from Tenant commence and diligently pursue to rebuild or
         repair, Tenant may at its option terminate this Lease by notice in
         writing to Landlord within thirty (30) days after the date of such
         damage or destruction, or within thirty (30) days after it has received
         notice of such taking, as the case may be. If either Landlord or Tenant
         exercises such option, this Lease shall terminate on the date
         designated in its notice of termination, which shall be not less than
         fifteen (15) nor more than thirty (30) days after the date of such
         notice.
<PAGE>

         (c)      If this Lease is not terminated pursuant to the provisions of
         Paragraph 18(a) above, this Lease shall continue in full force and
         effect and a just proportion of the Annual Rent shall be suspended or
         abated until the Premises shall be put by Landlord in proper condition
         for use, which Landlord covenants to do with reasonable diligence and
         to the extent permitted by the net proceeds of insurance recovered or
         damages awarded for such destruction or taking, and subject to zoning
         and building laws then in existence. "Net proceeds of insurance
         recovered or damaged awarded" refers to the gross amount of such
         insurance or award less the reasonable expenses of Landlord in
         connection with the collection of same, including without limitations,
         reasonable fees and expenses for legal and appraisal services. In the
         case of a taking which permanently reduces the Square Footage of the
         Premises, the rent shall be abated for the remainder of the Term in
         proportion to the amount by which the Square Footage has been reduced.

         (c) Irrespective of the form in which recovery may be had by law, all
         rights to damages or compensation shall belong to Landlord in all
         cases, except for damages to Tenant's fixtures, property or equipment,
         and for damages, if any, separately awarded for relocation expenses and
         business interruption, provided that none of the same shall reduce the
         damages or compensation which Landlord would otherwise recover. Tenant
         hereby grants to Landlord all of Tenant's rights to such damages and
         awards and covenants to deliver such further assignments thereof as
         Landlord may from time to time request.

19.      TENANT'S DEFAULT.

         (a) EVENTS OF DEFAULT. The following shall be "Events of Default" under
this Lease:

                  (i)  If Tenant shall fail to pay any monthly installment of
                  Annual Rent or Additional Rent when due and such default shall
                  continue for ten (10) days after written notice from Landlord;
                  provided that no such notice shall be required if Tenant has
                  received a similar notice within three hundred sixty-five
                  (365) days prior to such violation or failure;

                  (ii) If Tenant shall fail to timely make any other payment

                  ten (10) days after written notice from Landlord; provided
                  that no such notice shall be required if Tenant has received a
                  similar notice within three hundred sixty-five (365) days
                  prior to such violation or failure;

                  (iii) If Tenant shall violate or fail to perform any of the
                  other terms, conditions, covenants or agreements herein made
                  by Tenant, if such violation or failure continues for a period
                  of thirty (30) days after Landlord's written notice thereof to
                  Tenant; provided that no such notice shall be required if
                  Tenant has received a similar notice within three hundred
                  sixty-five (365) days prior to such violation or failure;

                  (iv) Tenant's becoming insolvent, as that term is defined in
                  Title 11 of the United States Code, entitled Bankruptcy, 11
                  U.S.C. Section 101 et. seq. (the "Bankruptcy Code"), or under
                  the insolvency laws of any State, District, Commonwealth or
                  Territory of the United States (the "Insolvency Laws");

                  (v)  the appointment of a receiver or custodian for all or a
                  substantial portion of Tenant's property or assets, or the
                  institution of a foreclosure action upon all or a substantial
                  portion of Tenant's real or personal property;

                  (vi) the filing of a voluntary petition under the provisions
                  of the Bankruptcy Code or Insolvency Laws;


<PAGE>


                  (vii) the filing of an involuntary petition against Tenant as
                  the subject debtor under the Bankruptcy Code or Insolvency
                  Laws, which is either not dismissed within forty-five (45)
                  days of filing, or results in the issuance of an order for
                  relief against the debtor, whichever is earlier;

                  (viii) Tenant's making or consenting to an assignment for the
                  benefit of creditors or a common law composition of creditors;
                  or

                  (ix) Tenant's interest in this Lease being taken on execution
                  in any action against the Tenant.

         (b)      LANDLORD'S REMEDIES. Should an Event of Default occur under
                  this Lease, Landlord may pursue any or all of the following
                  remedies:

                  (i)      TERMINATION OF LEASE. Landlord may terminate this
                  Lease by giving written notice of such termination to Tenant,
                  or by reentry, whereupon the mailing of such notice of
                  termination addressed to Tenant, or in the case of reentry,
                  upon such reentry, with or without notice or demand and with
                  or without process of law (forcibly if necessary), this Lease
                  shall automatically cease and terminate and Tenant shall be
                  immediately obligated to quit the Premises. Termination by
                  entry or notice as provided herein shall be effective and
                  complete upon entry or the mailing of notice, respectively,
                  and shall require no further action on the part of Landlord
                  including, without limitation, resort to legal process under
                  applicable law. Any other notice to quit or notice of
                  Landlord's intention to reenter the Premises is hereby
                  expressly waived. If Landlord elects to terminate this Lease,
                  everything contained in this Lease on the part of Landlord to
                  be done and performed shall cease without prejudice, subject,
                  however, to the right of Landlord to recover from Tenant all
                  Annual Rent and Additional Rent and any other sums accrued up
                  to the time of termination or recovery of possession by
                  Landlord, whichever is later.

                  (ii)     SUIT FOR POSSESSION. Landlord may proceed to recover
                  possession of the Premises under and by virtue of the
                  provisions of the laws of the state in which the Premises are
                  located or by such other proceedings, including reentry and
                  possession, as may be applicable.

                  (iii)    RELETTING OF PREMISES. Should this Lease be
                  terminated before the expiration of the Term of this Lease by
                  reason of Tenant's default as hereinabove provided, or if
                  Tenant shall abandon or vacate the Premises before the
                  expiration or termination of the Term of this Lease without
                  having paid the full rental for the remainder of such Term,
                  Landlord shall have the option, but not the obligation, to
                  relet the Premises for such rent and upon such terms as are
                  not unreasonable under the circumstances and, if the full
                  Annual Rent and Additional Rent reserved under this Lease (and
                  any of the costs, expenses or damages indicated below) shall
                  not be realized by Landlord, Tenant shall be liable for all
                  damages sustained by Landlord, including, without limitation,
                  deficiency in rent, reasonable attorneys' fees, brokerage fees
                  and expenses of placing the Premises in first-class rentable
                  condition including without limitation any alterations and
                  improvements. Landlord, in putting the Premises in good order
                  or preparing the same for rerental may, at Landlord's option,
                  make such alterations, repairs or replacements in the Premises
                  as Landlord, in its sole judgment, considers advisable and
                  necessary for the purpose of reletting the Premises, and the
                  making of such alterations, repairs, or replacements shall not
                  operate or be construed to release Tenant from liability
                  hereunder as aforesaid. Landlord shall in no event be liable
                  in any way whatsoever for failure to relet the Premises, or in
                  the event that the Premises are relet, for failure to collect
                  the rent under such reletting, and in no event shall Tenant be
                  entitled to receive the excess, if any, of such net rent
                  collected over the sums payable by Tenant to Landlord
                  hereunder.


<PAGE>


                  (iv)     ACCELERATION OF PAYMENT. If Tenant shall fail to pay
                  any monthly installment of Annual Rent and/or Additional Rent
                  pursuant to the terms of this Lease, within ten (10) days of
                  the date when each such payment is due, for three (3)
                  consecutive months, or three (3) times in any period of twelve
                  (12) consecutive months, then Landlord may, by giving written
                  notice to Tenant, exercise any of the following options: (A)
                  declare the entire rent reserved under this Lease to be due
                  and payable within ten (10) days of such notice; (B) declare
                  the rent reserved under this Lease for the next six (6) months
                  (or at Landlord's option for a lesser period) to be due and
                  payable within ten (10) days of such notice; or (C) require an
                  additional security deposit to be paid to Landlord within ten
                  (10) days of such notice in an amount not to exceed six (6)
                  months rent. Landlord may invoke any of the options provided
                  for herein at any time during which an Event of Default
                  remains uncured.

                  (v)      MONETARY DAMAGES. Any damage or loss of rent
                  sustained by Landlord may be recovered by Landlord, at
                  Landlord's option, at the time of the reletting, or in
                  separate actions, from time to time, as said damage shall have
                  been made more easily ascertainable by successive relettings,
                  or at Landlord's option in a single proceeding deferred until
                  the expiration of the Term of this Lease (in which event
                  Tenant hereby agrees that the cause of action shall not be
                  deemed to have accrued until the date of expiration of said
                  Term) or in a single proceeding prior to either the time or
                  reletting or the expiration of the Term of this Lease. In
                  addition, should it be necessary for Landlord to employ legal
                  counsel to enforce any of the provisions herein contained,
                  Tenant agrees to pay all attorney's fees and court costs
                  reasonably incurred.

                  (vi)     ANTICIPATORY BREACH; CUMULATIVE REMEDIES. Nothing
                  contained herein shall prevent the enforcement of any claim
                  Landlord may have against Tenant for anticipatory breach of
                  the unexpired Term of this Lease. In the event of a breach or
                  anticipatory breach by Tenant of any of the covenants or
                  provisions hereof, Landlord shall have the right of injunction
                  and the right to invoke any remedy allowed at law or in equity
                  as if reentry, summary proceedings and other remedies were not
                  provided for herein. Mention in this Lease of any particular
                  remedy shall not preclude Landlord from any other remedy, in
                  law or in equity, whether or not mentioned herein. Landlord's
                  election to pursue one or more remedies, whether as set forth
                  herein or otherwise, shall not bar Landlord from seeking any
                  other or additional remedies at any time and in no event shall
                  Landlord ever be deemed to have elected one or more remedies
                  to the exclusion of any other remedy or remedies. Any and all
                  rights and remedies that Landlord may have under this Lease,
                  and at law and in equity, shall be cumulative and shall not be
                  deemed inconsistent with each other, and any two or more of
                  all such rights and remedies may be exercised at the same time
                  insofar as permitted by law. Tenant hereby expressly waives
                  any and all rights of redemption granted by or under any
                  present or future laws in the event of Tenant being evicted or
                  dispossessed for any cause, or in the event of Landlord
                  obtaining possession of the Premises, by reason of the
                  violation by Tenant of any of the covenants and conditions of
                  this Lease, or otherwise.

          (c) WAIVER. If, under the provisions hereof, Landlord shall institute
         proceedings against Tenant and a compromise or settlement thereof shall
         be made, the same shall not constitute a waiver of any other covenant,
         condition or agreement herein contained, nor of any of Landlord's
         rights hereunder. No waiver by Landlord of any breach of any covenant,
         condition or agreement herein contained shall operate as a waiver of
         such covenant, condition, or agreement itself, or of any subsequent
         breach thereof. No payment by Tenant or receipt by Landlord of a lesser
         amount than the monthly installments of rent herein stipulated shall be
         deemed to be other than on account of the earliest stipulated rent, nor
         shall any endorsement or statement on any check or letter accompanying
         a check for payment of Annual Rent, Additional Rent or any other sum be
         deemed an accord and satisfaction, and Landlord may accept such check
         or payment without prejudice to Landlord's right to recover the balance
         of such Annual Rent, Additional Rent or any other sum or so pursue any
         other remedy


<PAGE>


         provided in this Lease. No reentry by Landlord, and no acceptance by
         Landlord of keys from Tenant, shall be considered an acceptance of a
         surrender of the Lease or Premises.

          (d) RIGHT OF LANDLORD TO CURE TENANT'S DEFAULT. If Tenant defaults in
         the making of any payment or in the doing of any act herein required to
         be made or done by Tenant, then Landlord may, but shall not be required
         to, make such payment or do such act, and charge the amount of the
         expense thereof, if made or done by Landlord, with interest thereon at
         the rate per annum which is four percent (4%) greater than the "base
         lending rate" then in effect at The First National Bank of Boston,
         Boston, Massachusetts, or the highest rate permitted by law, whichever
         may be less; with it being the express intent of the parties that
         nothing herein contained shall be construed or implemented in such a
         manner as to allow Landlord to charge or receive interest in excess of
         the maximum legal rate then allowed by law. Such payment and interest
         shall constitute Additional Rent hereunder due and payable with the
         next monthly installment of Annual Rent; but the making of such payment
         or the taking of such action by Landlord shall not operate to cure such
         default or to stop Landlord from the pursuit of any remedy to which
         Landlord would otherwise be entitled.

          (e) LATE PAYMENT. If Tenant fails to pay any installment of Annual
         Rent and/or Additional Rent on or before the first (1st) day of the
         calendar month when such installment becomes due and payable, Tenant
         shall pay to Landlord a late charge of five percent (5%) of the amount
         of such installment, and, in addition, such unpaid installment shall
         bear interest at the rate per annum which is four percent (4%) greater
         than the "base lending rate" then in effect at The First National Bank
         of Boston, Boston, Massachusetts, or the highest rate permitted by law,
         whichever may be less; with it being the express intent of the parties
         that nothing herein contained shall be construed or implemented in such
         manner as to allow Landlord to charge or receive interest in excess of
         the maximum legal rate then allowed by law. Such late charge and
         interest shall constitute Additional Rent hereunder due and payable
         with the next monthly installment of Annual Rent due, or if payments
         have been accelerated pursuant to this Paragraph 19, due and payable
         immediately.

          (f) LIEN ON PERSONAL PROPERTY. INTENTIONALLY OMITTED.

20.  LIABILITY OF LANDLORD; INDEMNIFICATION.

         (a) Landlord shall not be liable to Tenant, its employees, agents,
         contractors, business invitees, licensees, customers, clients, family
         members or guests for any damage, compensation or claim arising from
         (i) the necessity of repairing any portion of the Premises, Building or
         Lot, (ii) the interruption in the use of the Premises, (iii) accident
         or damage to persons or property resulting from the use or operation
         (by Landlord, Tenant, or any other person or persons whatsoever) of the
         Premises or of any elevators or heating, cooling, electrical or
         plumbing equipment or apparatus in the Premises or Building, (iv) the
         termination of this Lease by reason of the destruction of the Premises,
         (v) any fire, robbery, theft, mysterious disappearance and/or any other
         casualty, (vi) any leakage in any part or portion of the Premises or
         the Building, or from water, rain or snow that may leak into, or flow
         from, any part of the Premises or the Building, or from drains, pipes
         or plumbing work in the Building, or from any other cause whatsoever,
         or (vii) for any personal injury arising from the use, occupancy and
         condition of the Premises, unless such personal injury is caused by the
         gross negligence of Landlord, or a willful act or failure to act on the
         part of Landlord. Tenant shall not be entitled to any abatement or
         diminution of rent as a result of any of the foregoing occurrences, nor
         shall the same release Tenant from its obligations hereunder or
         constitute an eviction. Any goods, property or personal effects of
         Tenant, its employees, agents, contractors, business invitees,
         licensees, customers, clients, family members or guests, stored or
         placed in or about the Premises, Building or Lot shall be at their
         risk, and the Landlord shall not in any manner be held responsible
         therefor. The employees of the Landlord are prohibited from receiving
         any packages or other articles delivered to the Building by Tenant, and
         if any such employee receives any such package or articles, such
         employee shall be the agent of the Tenant for such purposes and not of
         the Landlord. Tenant acknowledges that Landlord will not carry


<PAGE>


         insurance on Tenant's furniture, furnishings, fixtures, equipment
         and/or improvements in or to the Premises and Tenant shall have full
         responsibility therefor and shall bear the full risk of loss thereto.
         It is expressly understood and agreed that Tenant shall look to its
         business interruption and property damage insurance policies, and not
         to Landlord or its agents or employees, for reimbursement for any
         damages or losses incurred as a result of any of the foregoing
         occurrences, other than clause (a)(vii) above, and that said policies
         shall contain waiver of subrogation clauses.

         (b) If Landlord shall fail to perform any covenant, term or condition
         of this Lease upon Landlord's part to be performed or be guilty of
         negligence with regard to any party claiming by, under or through
         Tenant and, as a consequence of such default or negligence, Tenant
         shall recover a money judgment against Landlord, such judgment shall be
         satisfied only out of the proceeds of sale received upon execution of
         such judgment and levy thereof against the right, title and interest of
         Landlord in the Premises, Building and Lot, and neither Landlord nor
         any of the partners designated herein as Landlord comprising any
         partnership designated herein as Landlord or any trustees or
         beneficiaries designated herein as Landlord shall be personally liable
         for any judgment rendered against Landlord or any deficiency
         thereunder. It is agreed that in no event shall Tenant have any right
         to levy execution against any property of Landlord other than its
         interest in the Premises, Building and Lot and the rents or other
         income therefrom as hereinbefore expressly provided. In the event of
         sale or other transfer of Landlord's right, title and interest in the
         Premises, Building and Lot, Landlord shall be released from all
         liability and obligations hereunder. If all or any part of Landlord's
         interest in this Lease shall be held by a trust, no trustee,
         shareholder or beneficiary of such trust shall be personally liable for
         any of the covenants or agreements, expressed or implied, hereunder. IN
         NO EVENT SHALL LANDLORD EVER BE PERSONALLY LIABLE TO TENANT OR ANYONE
         CLAIMING BY, UNDER OR THROUGH TENANT FOR CONSEQUENTIAL DAMAGES, SUCH
         DAMAGES OR CLAIMS THEREFOR BEING HEREBY EXPRESSLY WAIVED BY TENANT.

         (c) Except to the extent caused by any willful or negligent act or
omission of Landlord or its agents, Tenant hereby agrees to indemnify and hold
Landlord harmless from and against any cost, damage, claim, liability or expense
(including attorney's fees) incurred by or claimed against Landlord, directly or
indirectly, which is occasioned by or results from any default hereunder or any
willful or negligent act or omission on the part of Tenant, its agents,
employees, contractors, invitees, licensees, customers, clients, family members
and guests, or as a result of or in any way arising from Tenant's use and
occupancy of the Premises, Building and/or Lot or in any other manner which
relates to the business of Tenant. Any such cost, damage, claim, liability or
expense incurred by Landlord for which Tenant is obligated to reimburse Landlord
shall be deemed Additional Rent due and payable as Additional Rent upon demand
by Landlord. It is expressly understood and agreed that Tenant's liability under
this Lease extends to the acts and omissions of any subtenant or assignee and
any agent, employee, contractor, invitee, licensee, customer, client, family
member and guest of any subtenant or assignee.

21.      LEASE NOT TO BE RECORDED. Tenant agrees that it will not record this
         Lease.

22.      SEVERABILITY. It is agreed that if any provision of this Lease shall be
         determined to be void by any court of competent jurisdiction, then such
         determination shall not affect any other provisions of this Lease, all
         of which other provisions shall remain in full force and effect; and it
         is the intention of the parties that if a 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.

23.      DELAYS. In any case where either party hereto is required to do any
         act, other than the payment of money including without limitation
         Annual Rent and Additional Rent, and is delayed in so doing by reason
         of or resulting from an Act of God, war, civil commotion, fire or other
         casualty, labor difficulties, shortages of labor, materials or
         equipment, government regulations or other causes beyond such party's
         reasonable control, such period of time shall not be counted in
         determining the time


<PAGE>


         during which such work or act shall be completed, whether such time
         shall be designated by a fixed date, a fixed time or "a reasonable
         time". In any case where work is to be paid for out of insurance
         proceeds or condemnation awards, due allowance shall be made for delays
         in the collection of such proceeds and awards.

24.      ESTOPPEL CERTIFICATES. Tenant and Landlord each agree from time to
         time, upon not less than fifteen (15) days prior written request, to
         execute, acknowledge and deliver to the other a statement in writing
         certifying that this Lease is unmodified and in full force and effect,
         or if modified, stating the modifications; that the requested party has
         no defenses, offsets or counterclaims against its obligations under
         this Lease (including Tenant's obligation to pay Annual Rent and
         Additional Rent) or, if there are any defenses, offsets, or
         counterclaims, setting them forth in reasonable detail; and setting
         forth the dates to which the Annual Rent and Additional Rent and other
         charges have been paid. Any such statement delivered pursuant to this
         paragraph may be relied upon by any prospective purchaser or mortgagee
         of the Premises, Building and/or Lot, or any prospective assignee of
         any such mortgage, or any prospective assignee of this Lease, or any
         other similarly interested party.

25.      WAIVER OF SUBROGATION. Tenant and Landlord each hereby release the
         other to the extent of their respective insurance coverage, from any
         and all liability for any loss or damage caused by fire or any of the
         extended coverage casualties or any other casualty insured against,
         even if such fire or other casualty shall be brought about by the fault
         or negligence of Tenant, Landlord or their agents. Tenant and Landlord
         agree that their respective policies covering such loss or damage shall
         contain a clause to the effect that this release shall not affect said
         policies or the right of Tenant or Landlord, as the case may be, to
         recover thereunder and otherwise acknowledging this mutual waiver of
         subrogation.

26.      WAIVER. No waiver of any condition or legal right or remedy shall be
         implied by the failure of Landlord to declare a forfeiture, or any
         other reasons, and no waiver of any condition or covenant shall be
         valid unless it be in writing signed by Landlord. No waiver by Landlord
         in respect to one tenant of the Building or Lot shall constitute a
         waiver in favor of any other tenant, nor shall the waiver or a breach
         of any condition or covenant be claimed or pleaded to excuse a future
         breach of the same condition or covenant. The mention in this Lease of
         any specific right or remedy shall not preclude Landlord from
         exercising any other right or from having any other remedy or from
         maintaining any action to which it may be otherwise entitled either at
         law or in equity; and for the purpose of any suit by Landlord brought
         or based on this Lease, this Lease shall be construed to be a divisible
         contract, to the end that successive actions may be maintained as
         successive periodic sums shall mature under this Lease. It is further
         agreed that failure to include in any suit or action any sum or sums
         then matured shall not be a bar to the maintenance of any suit or
         action for the recovering of said sum or sums so omitted at a later
         time.

27.      SURRENDER AND HOLDING OVER. Tenant shall deliver up and surrender to
         Landlord possession of the Premises upon the expiration of the Term of
         this Lease or its earlier termination in any way, broom clean and in as
         good condition and repair as the same shall be at the commencement of
         said Term (damage by fire and other perils covered by standard fire and
         extended coverage insurance and ordinary wear and tear, subject to
         Paragraph 9 of this Lease, only excepted), and shall deliver the keys
         at the office of Landlord or Landlord's agent. Should Tenant or any
         party claiming under Tenant remain in possession of the Premises, or
         any part thereof, after any termination of this Lease, no tenancy or
         interest in the Premises shall result therefrom but such holding over
         shall be an unlawful detainer and all such parties shall be subject to
         immediate eviction and removal, and Tenant shall upon demand pay to
         Landlord, as liquidated damages, a sum equal to 1.5 times the Annual
         Rent, Additional Rent and any other sums to be paid as specified herein
         for any period during which Tenant shall hold the Premises after the
         stipulated Term of this Lease may be terminated or have expired.


<PAGE>



28.      LEASE INURES TO BENEFIT OF SUCCESSORS AND ASSIGNS. Subject to the
         provisions hereof, this Lease and all the terms, covenants, provisions
         and conditions herein contained shall inure to the benefit of and be
         binding upon their respective successors and assigns including, without
         limitation, their heirs, personal representative, debtor in possession,
         trustee, custodian, receiver, or any similar functionary serving in
         proceedings brought by or against Landlord or Tenant (or their
         respective successors and assigns) under the Bankruptcy Code (as now or
         hereafter in effect), Insolvency Laws, or any similar laws relating to
         bankruptcy, insolvency or the adjustment of debts, provided, however,
         that no subletting or assignment by, from, through or under Tenant in
         violation of the provisions hereof shall vest in the subletees or
         assigns any right, title or interest whatever.

29.      QUIET ENJOYMENT. Landlord hereby covenants and agrees that if Tenant
         shall perform all the covenants, agreements and other provisions herein
         stipulated to be performed or observed on Tenant's part, Tenant shall
         at all time during the continuance hereof have the peaceable and quiet
         enjoyment and possession of the Premises without any manner of
         molestation or hindrance from Landlord or any person or persons
         lawfully claiming under Landlord, subject, however, to the terms of
         this Lease and any instruments having a prior lien. The rights granted
         by this Paragraph are in lieu of any other rights Tenant may have by
         statute or at law.

30.      NO PARTNERSHIP. Landlord does not, in any way or for any purpose,
         become a partner of Tenant in the conduct of its business, or
         otherwise, or joint venturer or a member of a joint enterprise with
         Tenant.

31.      NOTICES. Any notice or consent required to be given by or on behalf of
         either party to the other shall be in writing and shall be given by
         mailing such notice or consent by registered or certified mail, return
         receipt requested, postage prepaid, addressed, if to Landlord, at the
         address hereinabove specified, and, if to Tenant, at the address
         hereinabove specified if prior to the Commencement Date and thereafter
         to the Premises, or at such other address as may be specified from time
         to time in writing sent to the other party by like notice. Notices so
         given shall be deemed to be given and effective at the time they are
         deposited with the United States Postal Service.

32.      INTERPRETATION. Wherever either the word "Landlord" or "Tenant" is used
         in this Lease, it shall be considered as meaning the parties
         respectively, wherever the context permits or requires, and when the
         singular and/or neuter pronouns are used herein, the same shall be
         construed as including all persons and corporations designated
         respectively as Landlord or Tenant in this instrument wherever the
         context requires.

33.      PARAGRAPH HEADINGS. The paragraph headings are inserted only as a
         matter of convenience and for reference and in no way define, limit or
         describe the scope or intent of this Lease nor in any way affect this
         Lease.

34.      BROKER'S COMMISSIONS. Tenant warrants that there are no claims for
         broker's commission or finder's fees in connection with its execution
         of this Lease or the tenancy hereby created and agrees to indemnify and
         save Landlord harmless from any liability that may arise from such
         claim, including reasonable attorneys fees.

35.      INTERRUPTION OF SERVICES. With respect to any services furnished by
         Landlord to Tenant, Landlord shall in no event be liable for failure to
         furnish the same when prevented from doing so by strike, lockout,
         breakdown, accident, order or regulation of or by any governmental
         authority, or failure of supply, or inability by the exercise of
         reasonable diligence to obtain supplies, parts or employees necessary
         to furnish such services, or because of war or other emergency, or for
         any cause beyond Landlord's reasonable control, or for any cause due to
         any act or neglect of Tenant or its servants, agents,


<PAGE>


         employees, licensees or any person claiming by, through or under
         Tenant, and in no event shall Landlord ever be liable to Tenant for any
         indirect or consequential damages.

36.      SUBORDINATION. Upon the written request of Landlord, Tenant shall enter
         into a recordable agreement with the holder of any present or future
         mortgage of the Premises, Building or Lot which shall provide that (i)
         this Lease shall be subordinated to such mortgage, (ii) in the event of
         foreclosure of said mortgage or any other action thereunder by the
         mortgagee, the mortgagee (and its successors in interest) and Tenant
         shall be directly bound to each other to perform the respective
         undischarged obligations of Landlord and Tenant hereunder (in the case
         of Landlord accruing after such foreclosure or other action and in the
         case of Tenant whether accruing before or after such foreclosure or
         other action), (iii) this Lease shall continue in full force and
         effect, and (iv) Tenant's rights hereunder shall not be disturbed,
         except as in this Lease provided. The word "mortgage" as used herein
         includes mortgages, deeds of trust and all similar instruments, all
         modifications, extensions, renewals and replacements thereof, and any
         and all assignments of the Landlord's interest in this Lease given as
         collateral security for any obligation of Landlord. Landlord agrees to
         use its best efforts to obtain a Non-Disturbance Agreement.

37.      MODIFICATION. In the event that any holder or prospective holder of any
         mortgage, as hereinbefore defined, which includes the Premises as part
         of the mortgaged Premises, shall request any reasonable modification of
         any of the provisions of this Lease, other than a provision directly
         related to the Annual Rent, Additional Rent or other sums payable
         hereunder, the duration of the Term hereof, or the size, use or
         location of the Premises, Tenant agrees that Tenant will enter into a
         written agreement in recordable form with such holder or prospective
         holder which shall effect such modification and provide that such
         modification shall become effective and binding upon Tenant and shall
         have the same force and effect as an amendment to this Lease in the
         event of foreclosure or other similar action taken by such holder or
         prospective holder or by anyone claiming by, through or under such
         holder or prospective holder.

38.      MULTIPLE PARTIES. If Tenant shall consist of more than one person or if
         there shall be a guarantor of Tenant's obligations, then the liability
         of all such persons, including the guarantor, if any, shall be joint
         and several.

39.      SUBMISSION NOT AN OPTION. The submission of this Lease for examination
         and negotiation does not constitute an offer to lease, a reservation
         of, or option for the Premises and shall vest no right in any party.
         Tenant or anyone claiming under or through Tenant shall have the rights
         to the Premises as set forth herein and this Lease becomes effective as
         a Lease only upon execution, acknowledgment and delivery thereof by
         Landlord and Tenant, regardless of any written or verbal representation
         of any agent, manager or employee of Landlord to the contrary.

40.      FINANCIAL INFORMATION. It is hereby understood and agreed that Tenant
         will supply to the Landlord, on an annual basis, a copy of Tenant=s
         audited financial statement within ninety (90) days following Tenant=s
         fiscal year end. Any information obtained by Landlord pursuant to the
         provisions of this Paragraph shall be treated as confidential, except
         that Landlord may disclose such information to its lenders.


<PAGE>


41.      OPTION TO EXPAND. In the event Tenant has not been in default of any of
         the terms, conditions and covenants of this Lease Agreement and any
         Amendments made hereto during the term hereof, Tenant shall have the
         option to lease 18,674 square feet of space from the Landlord located
         on the first (1st) floor of 33 Cherry Hill Drive, Danvers, MA 01923,
         subject to availability and further subject, but not limited to, the
         following terms and conditions:

         1.       Tenant's additional space requirement must be for a minimum of
                  18,674 square feet of space (hereinafter referred to as the
                  "Expansion Premises").

         2.       Tenant must notify Landlord in writing ("Tenant's Notice") of
                  its additional space requirements six (6) months prior to the
                  date Tenant desires such Expansion Premises, but not prior to
                  January 1, 2001 and not later than January 31, 2001.

         amount unpaid on account of such Event of Default shall be paid) thirty
         (30) days from the Commencement Date of this Lease.
