                                      RENT

  4.1  ANNUAL BASE RENT.  Tenant agrees to pay to Landlord at the present
mailing address of Landlord, or as directed by Landlord, without notice, demand,
off-set or deduction, on the Rent Commencement Date and thereafter, monthly, in
advance, on the first day of each and every calendar month during the Lease
Term, a sum equal to the monthly Annual Base Rent specified in Section 1.2
hereof.

Annual Base Rent for any partial month shall be paid by Tenant at such rate on a
pro rata basis, and if the Lease Term commences on a day other than the first
day of a calendar month, the first payment which Tenant shall make shall be a
payment equal to a proportionate part of such monthly Annual Base Rent for the
partial month from the Rent Commencement Date to the first day of the succeeding
calendar month, and the monthly Annual Base Rent for such succeeding calendar
month.

  4.2  ADDITIONAL RENT.  Commencing as of the Rent Commencement Date, in
addition to the Annual Base Rent, Tenant shall pay the following as additional
rent under this Lease (collectively, "Additional Rent"):

     a. Operating Expenses. Commencing on the Rent Commencement Date, Tenant
        shall pay, as Additional Rent hereunder in equal monthly installments,
        Tenant's Proportionate Share of the amount by which Operating Expenses
        (as defined in Section 9.2) paid or incurred by Landlord in each
        calendar year during the term of this Lease following the Base Operating
        Year, exceeds the Base Operating Expenses, as more particularly set
        forth in Article IX.

     b. Taxes. Commencing on the Rent Commencement Date, Tenant shall pay as
        Additional Rent hereunder in equal monthly installments, Tenant's
        Proportionate Share of the amount by which Real Estate Taxes in any tax
        year or partial tax year during the term of the Lease exceeds the Base
        Tax amount, as more particularly set forth in Article IX.

 4.3 TENANT IMPROVEMENT ALLOWANCE

     a. General. Landlord grants to Tenant a tenant improvement allowance of
        $15.00 per rentable square foot of the Premises (the "Allowance") to be
        applied by Landlord for construction of Landlord's Work.

<PAGE>

     b. Tenant's Funds. Tenant shall be obligated and agrees to pay to Landlord
        all costs of Landlord's Work in excess of the Allowance (the "Tenant's
        Buildout Share"). In the event that Landlord estimates the total cost of
        the Landlord's Work will exceed the Allowance, Tenant agrees to deposit
        with Landlord the difference between the Allowance and the cost of
        Tenant's Buildout Share. Tenant shall deposit Tenant's Buildout Share
        within fifteen (15) days of Landlord's notice to Tenant of the
        exhaustion of the Allowance. This money will be held in escrow by the
        Landlord and will be used by the Landlord for payment of Landlord's Work
        once the Allowance has been exhausted.

     c. Excess Allowance. If and to the extent that there remains any unexpended
        Allowance after completion of Landlord's Work on the Premises, any such
        Allowance shall be applied towards Tenant's Annual Base Rent first due
        and payable under this Lease until such excess has been exhausted.

                                   ARTICLE V

                                USE OF PREMISES

  5.1  PERMITTED USE.  Tenant agrees that the Premises shall be used and
occupied by Tenant only for the purpose specified as the use thereof in Section
1.2 of this Lease, and for no other purpose or purposes.

Tenant further agrees to conform to the following provisions during the entire
Lease Term.

     a. Tenant shall cause all freight (including furniture, fixtures and
        equipment used by Tenant in the occupancy of the Premises) to be
        delivered to or removed from the Building and the Premises in accordance
        with reasonable rules and regulations established by Landlord therefor
        and Landlord may require that such deliveries or removals be undertaken
        during periods other than Normal Building Operating Hours;

     b. Tenant shall not place on the exterior of exterior walls (including both
        interior and exterior surfaces of windows and doors) or on any part of
        the Building outside the Premises, any sign, symbol, advertisement or
        the like visible to public view outside of the Premises except for a
        sign on the door of the Premises of the type commonly and customarily
        found in first-class office buildings for the purpose of identifying and
        locating the Premises, which sign shall always be subject to the prior
        approval of Landlord. Landlord has established standards for such signs
        and Tenant agrees to conform to the same and to submit for

                                       11
<PAGE>

        Landlord's prior approval a plan or sketch of the sign to be placed on
        such entry doors. Without limitation, lettering on windows and window
        displays are expressly prohibited.

        Landlord agrees, however, to maintain a tenant directory in the lobby of
        the Building in which will be placed Tenant's name and the location of
        the Premises in the Building;

     c. Tenant shall not perform any act or any practice which may injure the
        Premises, or any other part of the Building, or cause any offensive
        odors or loud noise, or constitute a nuisance or a menace to any other
        tenant or tenants or other persons in the Building, or be detrimental to
        the reputation or appearance of the Building;

     d. Tenant shall conduct Tenant's business in the Premises in such a manner
        that Tenant's invitees shall not collect, line up or linger in the lobby
        or corridors of the Building, but shall be entirely accommodated within
        the Premises;

     e. Tenant shall comply and shall cause all employees to comply with all
        rules and regulations from time to time reasonably established by
        Landlord by suitable notice. Landlord shall not, however, be responsible
        for the noncompliance with any such rules and regulations by any other
        tenant or occupant of the Building, but Landlord shall not discriminate
        against Tenant in the enforcement of such rules and regulations;

     f. Tenant shall not use the name of the Building directly or indirectly in
        connection with Tenant's business, except as a part of Tenant's address,
        and Landlord reserves the right to change the name of the Building at
        any time;

     g. Except for products normally found in business offices (which products
        shall be used and disposed of in accordance with applicable local, state
        and federal laws) Tenant shall not use, handle or store or dispose of
        any oil, hazardous or toxic materials or hazardous or toxic wastes in or
        about the Building. If the transportation, storage, use or disposal of
        hazardous or toxic materials anywhere on the Land in connection with
        Tenant's use of the Premises results in (1) contamination of the soil or
        surface or ground water or (2) loss or damage to person(s) or property,
        then Tenant agrees to respond in accordance with the following
        paragraph:

                                       12
<PAGE>

        Tenant agrees (i) to notify Landlord immediately of any contamination,
        claim of contamination, loss or damage, (ii) after consultation and
        approval by Landlord, to clean up the contamination in full compliance
        with all applicable statutes, regulations and standards, and (iii) to
        indemnify, defend and hold Landlord harmless from and against any
        claims, suits, causes of action, costs and fees, including attorneys'
        fees, arising from or connected with any such contamination, claim of
        contamination, loss or damage. This provision shall survive the
        termination of this Lease. No consent or approval of Landlord shall in
        any way be construed as imposing upon Landlord any liability for the
        means, methods, or manner of removal, containment or other compliance
        with applicable law for and with respect to the foregoing; and

     h. Tenant agrees that, within the Premises, it shall be responsible for
        compliance with the Americans with Disabilities Act (42 U.S.C. (S) 12101
        et. seq.) and the regulations and Accessibility Guidelines for Buildings
        and Facilities issued pursuant thereto (the "ADA"), but Landlord shall
        conduct all improvements in the Premises in compliance with the ADA as a
        part of Landlord's Work.

  5.2  ALTERATIONS.  After initial completion of any work to be done by Tenant,
for which provision is made herein in EXHIBIT D attached hereto, Tenant shall
not alter or add to the Premises, except in accordance with written consent from
Landlord, which Landlord agrees not unreasonably to withhold as to nonstructural
alterations or additions.  All alterations made by Tenant shall be made in
accordance with all applicable laws, in a good and first-class workmanlike
manner and in accordance with the requirements of Landlord's insurers and
Tenant's insurers.  Any contractor or other person undertaking any alterations
of the Premises on behalf of Tenant shall be covered by Comprehensive General
Liability and Workmen's Compensation insurance with coverage limits reasonably
acceptable to Landlord and evidence thereof shall be furnished to Landlord prior
to the performance by such contractor or person of any work in respect of the
Premises.  All work performed by Tenant in the Premises shall remain therein
(unless, at the time Tenant requests Landlord's approval thereof, Landlord
directs Tenant to remove the same on termination) and, at termination, shall be
surrendered as a part thereof, except for Tenant's usual fixtures, trade
furniture and equipment, if movable, installed prior to or during the Lease Term
at Tenant's cost, which fixtures, trade furniture and equipment Tenant may
remove upon the termination of this Lease.  Tenant agrees to repair any and all
damage to the Premises resulting from such removal (including removal of
Tenant's improvements directed by Landlord as provided above) or, if Landlord so
elects, to pay Landlord for the reasonable cost of any such repairs forthwith
after billing therefor.

                                  ARTICLE VI

                           ASSIGNMENT AND SUBLETTING

  6.1 GENERAL. Notwithstanding any other provisions of this Lease, except as set
forth below, Tenant covenants and agrees that it will not assign this Lease or
sublet (which term, without limitation, shall include the granting of
concessions, licenses, management arrangements and the like) the whole or any
part of the Premises without, in each instance, having first received the
express written consent of Landlord, which consent shall not be unreasonably
withheld or delayed. Any assignment of this Lease, or subletting of the whole or
any part of the Premises (other than as permitted to a subsidiary or a
controlling corporation or entity as set forth below) by Tenant without
Landlord's express consent shall be invalid, void and of no force or effect.
Notwithstanding anything to the contrary in this Lease, if Tenant assigns or
sublets any portion of the Leased Premises, without Landlord's written
authorization, then Landlord reserves the right to begin dealing directly with
the subtenant without waiving any of the Landlord's rights under this lease
against the original Tenant and without notice to the original Tenant.

  6.2  NOTICE.  At least thirty (30) days prior to any sublease of the Premises
to another party or fifteen (15) days prior to any assignment of this Lease to a
new entity, Tenant shall provide Landlord written notice of such proposed
sublease or assignment containing the name and address of the proposed
assignee/sublessee, information as to its reputation, information as to its
financial condition, the intended use of the Premises, a copy of the proposed
sublease or assignment, and any other reasonable information the Landlord may
request before rendering a decision and any information provided shall be
treated as Tenant's warranty in respect of the information submitted therewith
to the best of Tenant's knowledge.  Landlord will consider the following factors
in making its decision regarding the proposed assignment/sublet.  This list is
illustrative and not intended to be a complete list of criteria the Landlord
will consider: (i) demonstrated financial stability and credit worthiness; (ii)
reputation of business; (iii) type of business; (iv) source of rent, including
financial conditions and operating performance of proposed assignee/sublessee;
(v) security provided to Landlord by Tenant and proposed assignee/sublessee of
future performance; (vi) expected rent to be paid by proposed
assignee/sublessee; and (vii) assurance sublessee's use will not cause Landlord
to be in violation of any other leases which limit the business type or uses by
other tenants in the building.

  6.3  TENANT REMAINS LIABLE.  In any case where Landlord shall consent to such
assignment or subletting, the Tenant named herein shall remain fully liable for
the obligations of Tenant hereunder, including, without limitation,

                                       14
<PAGE>

the obligation to pay the Annual Base Rent and other amounts provided under this
Lease.

  6.4  GENERAL CONDITIONS.  It shall be a condition of the validity of any such
assignment or subletting that the assignee or sublessee agrees directly with
Landlord, in form reasonably satisfactory to Landlord, to be bound by all the
obligations of Tenant hereunder, including, without limitation, the obligation
to pay Annual Base Rent and other amounts provided for under this Lease and the
covenant against further assignment and subletting, but such assignment or
subletting shall not relieve the Tenant named herein of any of the obligations
of Tenant hereunder, and Tenant shall remain fully liable therefor.  In no
event, however, shall Tenant assign this Lease or sublet the whole or any part
of the Premises to a proposed assignee or sublessee which has been judicially
declared bankrupt or insolvent according to law, or with respect to which an
assignment   has been made of property for the benefit of creditors, or with
respect to which a receiver, guardian, conservator, trustee in involuntary
bankruptcy or similar officer has been appointed to take charge of all or any
substantial part of the proposed assignee's or sublessee's property by a court
of competent jurisdiction or with respect to which a petition has been filed for
reorganization under any provisions of the Bankruptcy Code now or hereafter
enacted, or if a proposed assignee or sublessee has filed a petition for such
reorganization, or for arrangements under any provisions of the Bankruptcy Code
now or hereafter enacted and providing a plan for a debtor to settle, satisfy or
extend the time for the payment of debts.  Tenant shall, upon demand, reimburse
Landlord legal for the fees and expenses incurred by Landlord in processing any
request to assign this Lease or to sublet all or any portion of the Premises,
whether or not Landlord agrees thereto, and if Tenant shall fail promptly so to
reimburse Landlord, the same shall be a default in Tenant's monetary obligations
under this Lease.

  6.5  RECAPTURE.  Without limiting Landlord's discretion to grant or withhold
its consent to any proposed assignment or subletting, if Tenant requests
Landlord's consent to assign this Lease or sublet all or any portion of the
Premises, Landlord shall have the option, exercisable by written notice to
Tenant given within fifteen ( 15) days after Landlord's receipt of such request,
to terminate this Lease as of the date specified in such notice which shall be
not less than fifteen (15) nor more than forty-five (45) days after the date of
such notice for the entire Premises, in the case of an assignment or subletting
of the whole, and for the portion of the Premises, in the case of a subletting
of a portion.  In the event of termination in respect of a portion of the
Premises, the portion so eliminated shall be delivered to Landlord on the date
specified in good order and condition in the manner provided in Section 4.2 at
the end of the Lease Tenn and thereafter, to the extent necessary in Landlord's
reasonable judgment, Landlord, at its own cost and expense, may have access to
and may make modification to the Premises so as to make such portion a

                                       15
<PAGE>

self-contained rental unit with access to common areas, elevators and the like.
Annual Base Rent and Tenant's Proportionate Share shall be adjusted according to
the extent of the Premises for which the Lease is terminated.

  6.6  PROFIT.  Without limitation of the rights of Landlord hereunder in
respect thereto, if there is any assignment of this Lease by Tenant for
consideration or a subletting of the whole of the Premises by Tenant at a rent
which exceeds the rent payable hereunder by Tenant, or if there is a subletting
of a portion of the Premises by Tenant at a rent in excess of the subleased
portion's pro rata share of the rent payable hereunder by Tenant, then Tenant
shall pay to Landlord, as Additional Rent, forthwith upon Tenant's receipt of
the consideration (or the cash equivalent thereof) therefor, in the case of an
assignment, and in the case of a subletting, the full amount of any such excess
rent after deductions for the cost of tenant improvements provided by Tenant,
documented to the reasonable satisfaction of Landlord, brokerage commissions
paid by the Tenant and attorneys' fees.  The provisions of this paragraph shall
apply to each and every assignment of the Lease and each and every subletting of
all or a portion of the Premises, other than a Permitted Transaction pursuant to
Section 6.7 hereof, in each case on the terms and conditions set forth herein.
For the purposes of this Article VI, the term "Rent" shall mean all Annual Base
Rent, Additional Rent or other payments and/or consideration payable by one
party to another for the use and occupancy of all or a portion of the Premises.

  6.7  PERMITTED TRANSACTIONS.  The provisions of this Article VI shall not,
however, be applicable to an assignment of this Lease or a sublease by Tenant to
a subsidiary or an affiliate of Tenant or to an entity acquiring substantially
all of the stock or assets of Tenant (a "Permitted Transaction") as long as the
net worth of the assignee, sublessee or the Tenant, as the case may be, does not
decrease as a result of such transaction.  No such assignment or sublease shall
relieve the Tenant herein named of any of its obligations hereunder, and Tenant
shall remain fully liable therefor.  In cases of Permitted Transactions, Tenant
shall give Landlord fifteen (15) days' written notice of any assignment or
sublease.  Tenant shall provide Landlord written notice of such proposed
sublease or assignment containing the name and address of the proposed assignee,
information as to its reputation, information as to its financial condition, the
name of the new entity to be created, if any such additional information as
Landlord shall reasonably request.

                                  ARTICLE VII

              DELIVERY OF PREMISES AND RESPONSIBILITY FOR REPAIRS
                           AND CONDITION OF PREMISES

  7.1 DELIVERY OF POSSESSION OF PREMISES. The Premises shall be treated as
delivered hereunder upon the date on which Landlord's architect or engineer
shall give Tenant notice that the Landlord's Work has reached Substantial
Completion, but in no event sooner than January 1, 1999.

The term "Substantial Completion" shall mean (i) completion of the Landlord's
Work to such condition of completeness so as to obtain a certificate of use and
occupancy (including a temporary certificate) from the City of Marlborough for
the Premises in order that Tenant may occupy the Premises; (ii) the shell and
core of the Building are complete and in substantial compliance with all
applicable laws, statutes, codes, rules and regulations (collectively, "Laws")
and all of the Building's heating, ventilating, air-conditioning ("HVAC"),
plumbing, life safety, telephone, cable, if any, mechanical and electrical
systems (collectively, "Building Systems") are operational to the extent
necessary to service the Premises; (iii) Tenant has been provided with the
number of parking spaces to which it is entitled under this Lease; and (iv)
Tenant has executed and delivered a subordination, attornment and non-
disturbance agreement in the form attached hereto as EXHIBIT E and has received
an original executed by Landlord and each mortgagee of record, if applicable.
The existence of "punchlist" items remaining outstanding which do not
unreasonably interfere with general occupancy by Tenant shall not prevent
Substantial Completion, but Landlord shall use diligent efforts to promptly
complete such punchlist items without unreasonable interference with Tenant's
business.

To the extent that the date of the Substantial Completion of Landlord's Work is
delayed beyond the Estimated Commencement Date by reason of (i) Tenant's failure
to approve Construction Drawings (as defined below); or (ii) changes requested
by Tenant in Landlord's Work following approval by Tenant of the Final Schematic
Plan (which shall be defined as those design and development drawings provided
by the Landlord's Architect, Planners Designers Architects, Inc. ("PDA")); or
(iii) Tenant's failure to pay any amounts due from Tenant, if any, in excess of
the Allowance, to fund Landlord's Work (collectively, "Tenant Delay"), the date
of Substantial Completion shall be the Lease Commencement Date, however, the
Rent Commencement Date will not be similarly changed or extended.

  7.2  LANDLORD'S WORK.  Landlord will construct, install or perform in the
Premises those improvements and work agreed upon by Landlord and Tenant that is
necessary for Tenant to occupy the Premises.  Landlord's Work shall be

                                       17
<PAGE>

conducted in a first-class manner and in accordance with the provisions of this
Article VII.

Unless otherwise directed by Tenant in writing, Landlord's goal will be to
negotiate a final set of construction documents with the contractor to enable
construction of Landlord's Work within the aggregate Allowance of $15.00 per
rentable square foot. The stages of the buildout, time periods during which the
stages will occur and the respective obligations of Landlord and Tenant are set
forth below in this Article VII.

Landlord shall enter into an agreement with PDA through its affiliate, Dacon
Corporation, for the following design services: (i) architectural; (ii)
structural and engineering; (iii) civil engineering; (iv) mechanical engineering
services, including HVAC, plumbing and fire protection; and (v) the final
construction plans and outline specifications (the "Construction Drawings"). The
final Construction Drawings shall be incorporated into this Lease as EXHIBIT F
and shall be the final and determinative description of the Landlord's Work.

Landlord shall perform Landlord's Work by entering into a cost plus a fee with
guaranteed maximum price contract for completion of the Landlord's Work with
Dacon Corporation ("Dacon") of Natick, Massachusetts, the general contractor for
the Base Building and improvements to the Land. Tenant shall have no
relationship with the contractor except to the extent of Tenant's obligations to
participate in the finalization of the Final Schematic Plan of Landlord's Work,
and Tenant's approval of the final Construction Drawings.

  7.3  SCHEDULE.  Design, approval by Tenant and completion of Landlord's Work
shall be accomplished under the following phases and time periods:

     a. Preliminary. Tenant has previously approved Final Schematic Plans
        drafted by PDA. Landlord has contracted with PDA for the completion of
        the Construction Drawings that will become the final Landlord's Work.
        Landlord has provided Tenant with a form of a contract to be used
        between Landlord and the contractor chosen to complete Landlord's Work.

     b. October 16, 1998. Landlord will provide Tenant with Dacon's guaranteed
        maximum price ("Dacon's GMP") for the cost of completing Landlord's
        Work. Tenant will provide Landlord with its contractor's, ("Tenant's
        Contractor"), guaranteed maximum price. The contractor chosen by Tenant
        must be approved by Landlord in writing.

        (i)   If Dacon's GMP is at or below the Allowance, the Landlord shall
              notify Tenant of Dacon's GMP but Landlord shall not be required to
              seek the permission of the Tenant before commencing Landlord's
              Work.

                                       18
<PAGE>

        (ii)  If Dacon's GMP is within $20,000 of the Allowance, Tenant may
              either (a) conduct value engineering so as to reduce the cost of
              Landlord's Work; or (b) agree to Dacon's GMP.

        (iii) If Dacon's GMP is $20,000 or more over the Allowance and Tenant's
              Contractor is able to complete the Landlord's Work for less than
              Dacon's GMP, then:

               (a) Landlord shall have the opportunity to negotiate with Dacon
                   to reduce Dacon's GMP and if Dacon will not lower its GMP to
                   match Tenant's Contractor's price, the Landlord shall
                   negotiate and enter into a contract with Tenant's Contractor
                   for the completion of Landlord's Work. Said contract with
                   Tenant's Contractor will be in substantially the same form as
                   provided to Tenant by Landlord. Tenant's Contractor must
                   execute the contract with Landlord within five (5) business
                   days of notice to the Tenant's Contractor that it has been
                   chosen to complete the Landlord's Work. If Tenant's
                   Contractor fails to execute the contract within five (5)
                   business days, Landlord will enter into a contract with Dacon
                   to complete the Landlord's Work.

     c. On or before October 30, 1998. Landlord will deliver the final
        Construction Drawings to the Tenant. Tenant shall have two (2) days to
        approve the Construction Drawings or to set forth its reasons for
        disapproval. If Tenant makes any changes to the Construction Drawings
        that are inconsistent with the Final Schematic Plans, this will
        constitute a Tenant Delay.

 7.4 OTHER CONSTRUCTION PROVISIONS.

     a. Landlord shall permit Tenant access (at Tenant's sole risk) for purpose
        of installing equipment and furnishings in the Premises prior to
        Tenant's taking possession of the Premises if it can be done without
        interference with Landlord's Work in the Premises and/or in other
        portions of the Building and in harmony with Landlord's contractors and
        subcontractors, including, without limitation, in accordance with any
        labor agreements Landlord's contractors or subcontractors may be parties
        to.

     b. Tenant's Contractor Delay.

                                       19
<PAGE>

          (i) If Tenant's Contractor shall be the contractor chosen to complete
              Landlord's Work and if, for any reason, due to the fault of
              Tenant's Contractor, but not Force Majeure, the Premises have not
              been delivered to Tenant with Landlord's Work Substantially
              Complete on or before ninety (90) days after the Estimated
              Commencement Date, Tenant shall have the right to terminate this
              Lease, by written notice to the Landlord given within seven (7)
              days of the expiration of the ninety (90) day period. If Tenant
              does not issue such notice within the seven (7) day period and
              Landlord delivers the Premises with all the Landlord's Work
              Substantially Complete, Tenant's right to terminate under this
              subsection 7.4(b)(i) shall terminate and be of no further force or
              effect.

         (ii) If, for any reason, due to the fault of Tenant's Contractor or
              Force Majeure, the Premises have not been delivered to Tenant with
              the Landlord's Work Substantially Complete on or before one
              hundred fifty (150) days after the Estimated Commencement Date,
              Tenant shall have the right to terminate this Lease by written
              notice to the Landlord given within seven (7) days of the
              expiration of the one hundred fifty (150) day period. If Tenant
              does not issue such notice with the seven (7) day period and
              Landlord delivers the Premises with all the Landlord's Work
              Substantially Complete, Tenant's right to terminate under this
              subsection 7.4(b)(ii) shall terminate and be of no further force
              or effect.

  7.5  REPAIRS TO BE MADE BY LANDLORD.  Except as otherwise provided in this
Lease, Landlord agrees to keep in good order, condition and repair, the roof,
the exterior walls and the common areas of the Building, insofar as any of the
foregoing affects the Premises.  Landlord shall in no event be responsible to
Tenant for the condition of glass in and about the Premises or for the doors
leading to the Premises, or for any condition in the Premises or the Building
caused by any act or neglect of Tenant or any contractor, agent, employee or
invitee of Tenant, or anyone claiming by, through or under Tenant.

Landlord shall not be responsible to make any improvements or repairs to the
Building or the Premises other than as expressed in this Section 7.5 unless
expressly otherwise provided in this Lease. Landlord shall never be liable for
any failure to make repairs which, under the provisions of this Section 7.5 or
elsewhere in this Lease, Landlord has undertaken to make unless: (i) Tenant has
given notice to Landlord of the need to make such repairs as a result of a
condition in the Building or in the Premises requiring any repair for which
Landlord is responsible; and (ii) Landlord has failed to commence to make

                                       20
<PAGE>

such repairs within a reasonable time after receipt of such notice if any
repairs are, in fact, necessary.

  7.6  TENANT'S AGREEMENT.  Tenant agrees that Tenant will keep neat and clean
and maintain in good order, condition and repair, the Premises and every part
thereof throughout the Lease Term, excepting only those repairs for which
Landlord is responsible under the terms of this Lease and damage by fire or
other casualty or as a consequence of the exercise of the power of eminent
domain, and shall surrender the Premises at the end of the term, in such
condition.  Without limitation, Tenant shall maintain and use the Premises in
accordance with all applicable laws, ordinances, governmental rules and
regulations, directions and orders of officers of governmental agencies having
jurisdiction and in accordance with the requirements of Landlord's and/or
Tenant's insurers, and shall, at Tenant's own expense, obtain and maintain in
effect all permits, licenses and the like required by applicable law.  Tenant
shall not permit or commit any waste, and Tenant shall be responsible for the
cost of repairs which may be made necessary by reason of damage to any areas in
the Building, including the Premises, by Tenant, Tenant's contractors or
Tenant's agents, employees or invitees, or anyone claiming by, through or under
Tenant.  Landlord may replace as needed any bulbs and ballasts in the Premises
during the Lease Term at Tenant's cost and expense, or Landlord may require
Tenant to replace the same, at Tenant's cost and expense.

If repairs are required to be made by Tenant pursuant to the terms hereof,
Landlord may demand that Tenant make the same forthwith, and if Tenant refuses
or neglects to commence such repairs and complete the same with reasonable
dispatch after such demand, Landlord may (but shall not be required to do so)
make or cause such repairs to be made and shall not be responsible to Tenant for
any loss or damage that may accrue to Tenant's stock or business by reason
thereof unless caused by Landlord's negligence or willful misconduct. If
Landlord makes or causes such repairs to be made, Tenant agrees that Tenant will
forthwith, on demand, pay to Landlord the reasonable cost thereof, and if Tenant
shall default in such payment, Landlord shall have the remedies provided for the
nonpayment of rent or other charges payable hereunder.

  7.7  FLOOR LOAD - HEAVY MACHINERY.  Tenant shall not place a load upon any
floor in the Premises exceeding the lesser of (a) the floor load per square foot
of area which such floor was designed to carry as certified by Landlord's
architect and (b) the floor load per square foot of area which is allowed by
law.  Landlord reserves the right to prescribe the weight and position of all
business machines, equipment and mechanical equipment, including scales, which
shall be placed so as to distribute the weight.  Business machines, equipment
and mechanical equipment shall be placed and maintained by Tenant at Tenant's
expense in settings sufficient, in Landlord's judgment, to

                                       21
<PAGE>

absorb and prevent vibration, noise and annoyance. Tenant shall not move any
safe, heavy machinery, heavy equipment, freight, bulky matter or fixtures into
or out of the Building without Landlord's prior consent.

If such safe, machinery, equipment, freight, bulky matter or fixtures requires
special handling, Tenant agrees to employ only persons holding a Master Rigger's
License to do said work, and that all work in connection therewith shall comply
with applicable laws and regulations. Any such moving shall be at the sole risk
and hazard of Tenant and Tenant will exonerate, indemnify and save Landlord
harmless against and from any liability, loss, injury, claim or suit resulting
directly or indirectly from such moving. Tenant shall schedule such moving at
such times as Landlord shall reasonably require for the convenience of the
normal operations of the Building.

                                 ARTICLE VIII

            SERVICES TO BE FURNISHED BY LANDLORD AND UTILITY CHARGES

 8.1 LANDLORD'S SERVICES.  Landlord covenants during the Lease Term:

     a. to provide heating and air-conditioning in the Premises during Normal
        Building Operating Hours during the normal heating and air-conditioning
        seasons;

     b. to furnish hot and cold water for ordinary toilet, lavatory and drinking
        purposes. If Tenant requires water for any other purpose, including
        without limitation, in connection with the business conducted in the
        Premises, Tenant shall pay the Landlord an appropriate charge stipulated
        by Landlord to reimburse Landlord for the cost of such water and related
        sewer use charge (including a charge to reimburse Landlord for the cost
        of metering Tenant's usage), provided that in no event shall such charge
        exceed the amount which Tenant would have had to pay to the public
        utility directly for the water requirements of Tenant in the Premises;

     c. to furnish non-exclusive passenger elevator service;

     d. to provide non-exclusive freight elevator service, subject to scheduling
        by Landlord;

     e. to furnish, through Landlord's employees or independent contractors, the
        services listed in EXHIBIT H, if any;

     f. to furnish, through Landlord's employees or independent contractors,
        additional Building operation services upon reasonable advance request

                                       22
<PAGE>

        of Tenant at rates from time to time established by Landlord to be paid
        by Tenant provided the same may be reasonably and conveniently provided
        by Landlord. Tenant hereby agrees to pay to Landlord the cost of such
        services as Additional Rent upon demand by Landlord; and

     g. to provide, during those hours not considered Normal Building Operating
        Hours, heating and air-conditioning, only when specifically requested by
        the Tenant. Any cost of providing heating and air conditioning to the
        Premises shall be borne entirely by the Tenant (and, if applicable,
        others requesting such services). Tenant shall pay Landlord the charge
        incurred by Landlord for the cost of such heating and air-conditioning
        use.

  8.2  PAYMENT OF UTILITY CHARGES.  With respect to electricity for lighting and
equipment in the Premises, if the same is separately metered, Tenant agrees to
pay all bills therefor promptly to the utility company furnishing the same and,
if requested by Landlord, provide Landlord with evidence of such payment.  If
such utility company shall have a lien on the Premises for nonpayment of such
charges and Tenant shall fail at any time to make payment of same, without
limitation of Landlord's rights on account of such failure, Tenant shall
thereafter, if requested by Landlord, pay to Landlord, when monthly Annual Base
Rent is next due and thereafter on Landlord's demand, an amount reasonably
estimated by Landlord to be sufficient to discharge any such lien in the event
of a further failure of Tenant to pay any such electric charges when due.
Landlord shall hold the amounts from time-to-time deposited under this Section
8.2 as security for payment of such electric charges without interest to Tenant
and may, without limitation of remedies on account of Tenant's failure to make
any subsequent payment of electric charges, use such amounts for such payments.
Such amount or such portion thereof as shall be unexpended at the expiration of
this Lease shall, upon full performance of all Tenant's obligations hereunder,
be repaid to Tenant without interest.

  8.3  ENERGY CONSERVATION.  Notwithstanding anything to the contrary in this
Article VIII or elsewhere in this Lease, Landlord shall have the right to
institute such policies, programs and measures as may be reasonably necessary or
desirable, in Landlord's discretion, for the conservation and/or preservation of
energy or energy related services, or as may be required to comply with any
applicable codes, rules and regulations, whether mandatory or voluntary.

                                  ARTICLE IX

                      REAL ESTATE TAXES AND OTHER EXPENSES

 9.1 TENANT'S SHARE OF REAL ESTATE TAXES.

     a. For the purposes of this Section:

        (i)   The term "Tax Period" shall mean the period during which Taxes (as
              hereinafter defined) are required to be paid under applicable law.
              Thus, under the law presently in effect in the Commonwealth of
              Massachusetts, Tax Period means the period from July 1 of a
              calendar year to June 30 of the subsequent calendar year. Suitable
              adjustment in the determination of Tenant's obligation under this
              Section 9.1 shall be made in the computation for any Tax Period
              which is greater than or less than twelve (12) full calendar
              months.

        (ii)  The term "Base Tax Year" shall refer to the Fiscal Year 2000
              (i.e., July 1, 1999 to June 30, 2000). In calculating, the Base
              Tax Year, Landlord shall use the tax rate from Fiscal Year 2000 as
              provided by the Tax Collector of the City of Marlborough and shall
              apply such tax rate by the amount of the assessment for the Land
              and Building once it is fully assessed as determined by the
              Assessor for the City of Marlborough.

        (iii) The term "Taxes" shall mean all real estate taxes and assessments
              (which term, for purposes of this provision, shall include water
              and sewer use charges), special or otherwise, levied or assessed
              upon or with respect to the Building and the Land or any part
              thereof and ad valorem taxes for any personal property of Landlord
              used in connection therewith. Should the Commonwealth of
              Massachusetts, or any political subdivision thereof, or any other
              governmental authority having jurisdiction over the Building and
              the Land, (1) impose a tax, assessment, charge or fee, which
              Landlord shall be required to pay, by way of substitution for or
              as a supplement to such real estate taxes and ad valorem personal
              property taxes, or (2) impose an income or franchise tax or a tax
              on rents in substitution for or as a supplement to a tax levied
              against the Building or the Land or any part thereof and/or the
              personal property used in connection with the Building or the Land
              or any part thereof, all such taxes, assessments, fees or charges
              (hereinafter defined as "in lieu of taxes") shall be deemed to
              constitute Taxes hereunder. Taxes shall also include, in the year
              paid, all fees and costs reasonably incurred by Landlord in
              seeking to obtain a reduction of, or a limit on the increase in,
              any Taxes, regardless of whether any reduction or limitation is
              obtained. Except as hereinabove provided with regard to "in lieu
              of taxes", Taxes shall not include any inheritance, estate,
              succession, transfer, gift, franchise, net income or capital stock
              tax.

                                       24
<PAGE>

     b. In the event that the Taxes imposed with respect to the Building and the
        Land shall be greater during any Tax Period than the Base Tax Amount:

         (i)  Tenant shall pay to Landlord, as Additional Rent, Tenant's
              Proportionate Share of the amount by which the Taxes imposed with
              respect to the Building and the Land for such Tax Period exceed
              the Base Tax Amount, apportioned for any fraction of a Tax Period
              contained within the Term, and

         (ii) Landlord shall submit to Tenant a statement setting forth the
              amount of such Additional Rent, and within fifteen (15) days after
              the delivery of such statement (whether or not such statement
              shall be timely), Tenant shall pay to Landlord the payment
              required under subparagraph (i) above. So long as Taxes shall be
              payable in installments under applicable law, Landlord may submit
              such statements to Tenant in similar installments. The failure by
              Landlord to send any statement required by this subparagraph shall
              not be deemed to be a waiver of Landlord's right to receive such
              Additional Rent.

     c. Tenant's share of Taxes shall be equitably adjusted for and with respect
        to any portion of the Term which does not include an entire Tax Period.

     d. If Tenant is obligated to pay any Additional Rent as aforesaid with
        respect to any Tax Period or fraction thereof during the Term, then
        Tenant shall pay, as Additional Rent, on the first day of each month of
        the next ensuing Tax Period, estimated monthly tax escalation payments
        in an amount from time to time reasonably estimated by Landlord to be
        sufficient to provide Landlord, in the aggregate, a sum equal to
        Tenant's Proportionate Share of the Taxes in excess of the Base Tax
        Amount, ten (10) days, at least, before the day on which payments on
        account of Taxes by Landlord would become delinquent. Estimated monthly
        tax escalation payments for each ensuing Tax Period shall be made
        retroactively to the first day of the Tax Period in question. Following
        the close of each Tax Period for and with respect to which Tenant is
        obligated to pay any Additional Rent as aforesaid, Landlord shall submit
        the statement set forth in paragraph (b)(ii) of this Section 9.1 and in
        the event the total of the estimated monthly tax escalation payments
        theretofore made by Tenant to Landlord for such Tax Period does not
        equal Tenant's Proportionate Share of the Taxes in excess of the Base
        Tax Amount for such Tax Period, Tenant shall pay any deficiency to
        Landlord as shown by such statement within fifteen (15) days after the
        delivery of such statement (whether or not such statement shall be

                                       25
<PAGE>

        timely). If the total of the estimated monthly tax escalation payments
        paid by Tenant during such Tax Period exceed the actual amount of
        Tenant's Proportionate Share of the Taxes in excess of the Base Tax
        Amount for said Tax Period, Landlord shall credit the amount of such
        overpayment against subsequent obligations of Tenant under this Lease
        (or refund such overpayment if the Term has ended and Tenant has no
        further obligations to Landlord under the Lease).

     e. When the applicable tax bill is not available prior to the end of the
        Term, then a tentative computation shall be made by Landlord on the
        basis of the Taxes for the next prior Tax Period, with a final
        adjustment to be made between Landlord and Tenant promptly after
        Landlord shall have received the applicable tax bill.

     f. Payments by Tenant to Landlord on account of Taxes shall not be
        considered as being held in trust, in escrow or the like, by Landlord;
        it being the express intent of Landlord and Tenant that Tenant shall in
        no event be entitled to receive interest upon, or any payments on
        account of earnings or profits derived from, such payments by Tenant to
        Landlord. Landlord shall have the same rights and remedies for the non-
        payment by Tenant of any amounts due on account of such Taxes as
        Landlord has hereunder for the failure of Tenant to pay the Annual Base
        Rent.

 9.2 TENANT'S SHARE OF OPERATING EXPENSES.

     a. For the purposes of this Section:

        (i)  The term "Operating Year" shall mean each successive fiscal year
             (as adopted by Landlord) in which any part of the Term of this
             Lease shall fall.

        (ii) The term "Operating Expenses" shall mean all expenses, costs and
             disbursements of every kind and nature, reasonably paid or incurred
             by Landlord in operating, owning, managing, leasing, repairing and
             maintaining the Building, the Land and their appurtenances
             including, but without limitation: premiums for fire, casualty,
             liability and such other insurance as Landlord may from time to
             time maintain; security expenses; compensation and all fringe
             benefits, workmen's compensation insurance premiums and payroll
             taxes paid by Landlord to, for or with respect to all persons
             engaged in operating, maintaining, managing or cleaning at or below
             the grade of building manager; fuel costs; steam, water, sewer,
             electric, gas, telephone, and other utility charges not otherwise
             billed to tenants by Landlord or the utility; expenses

                                       26
<PAGE>

             incurred in connection with the central plant furnishing heating,
             ventilating (including maintaining and repairing ventilating fans
             and fan rooms); and air conditioning to the Building, costs of
             lighting, costs of repairing and maintaining fire protection
             systems; costs of building and cleaning supplies and equipment
             (including rental); cost of maintenance, cleaning and repairs; cost
             of snow plowing or removal, or both, and care of interior and
             exterior landscaping; payments to independent contractors under
             contracts for cleaning, operating, management, maintenance and/or
             repair (which payments may be to affiliates of Landlord provided
             such charges are at reasonable and customary market rates) and a
             management fee of four percent (4%) of gross Building rental
             revenue; all other expenses paid in connection with cleaning,
             operating, management, maintenance and repair, costs of any capital
             improvements required by law or intended to reduce Operating
             Expenses, regardless of whether said capital improvement actually
             reduces said Operating Expenses, completed after the original
             construction of the Building, amortized by Landlord over their
             useful life determined in accordance with generally accepted
             accounting practices, with interest on the unamortized amount at
             the rate of the greater of (i) 12% per annum or (ii) 2% per annum
             above the base rate of interest charged from time to time by
             BankBoston or any successor or substitute regional bank selected by
             Landlord (but in no event at a rate which is more than the highest
             lawful rate allowable in the Commonwealth of Massachusetts).
             Operating Expenses shall not, however, include the following:

               (a) Costs of alterations of any tenant's premises or brokerage or
                   legal fees for a particular tenant and not for the benefit of
                   the Building or any group of tenants therein;

               (b) Principal or interest payments on loans secured by mortgages
                   or trust deeds on the Building and/or on the Land;

               (c) costs of correcting defects in the original construction of
                   the Building;

               (d) costs of services provided to other tenants of the Building
                   (for which a separate charge is made) and not to all tenants,
                   generally; and

               (e) costs of items covered by insurance or condemnation awards.

                                       27
<PAGE>

If less than ninety-five percent (95%) of the Building's rentable area shall
have been occupied by tenant(s) at any time during any Operating Year, Operating
Expenses shall be determined for such Operating Year to be an amount equal to
the like expense which would normally be expected to be incurred had such
occupancy been ninety-five percent (95%) throughout such Operating Year.

Notwithstanding anything to the contrary set forth herein, for any year
(including, without limitation, the Base Operating Year) in which other than
ninety-five percent (95%) of the rentable space in the Building is leased during
the entire year, all "Variable Components," as that term is defined below, of
Operating Expenses for such year shall be grossed-up, employing sound accounting
and property management principles, to the amount such Variable Components would
have been in the event the Building had been ninety-five percent (95%) leased
and occupied during the entire year by tenants paying full rent and the adjusted
amount of the Variable Components shall be used in determining Operating
Expenses for such year. "Variable Components" shall be those components that
vary based upon occupancy levels.

     b. After the expiration of each Operating Year, Landlord shall furnish
        Tenant with a statement setting forth the Operating Expenses for such
        Operating Year. Such statement shall be accompanied by a computation of
        the amount, if any, of the Additional Rent payable to Landlord pursuant
        to this Section.

     c. In the event the Operating Expenses during any Operating Year shall be
        greater than the Base Operating Expenses, Tenant shall pay to Landlord,
        as Additional Rent, an amount equal to Tenant's Proportionate Share of
        the excess of the Operating Expenses for such Operating Year over and
        above the Base Operating Expenses.

     d. Said Additional Rent shall, with respect to the Operating Years in which
        the Lease Commencement Date and end of the Term of this Lease fall, be
        adjusted to that proportion thereof as the portion of the Term of this
        Lease falling within such Operating Year bears to the full Operating
        Year. If Landlord shall change its fiscal year, appropriate adjustment
        shall be made for any Operating Year less than twelve months which may
        result.

     e. Any Additional Rent payable by Tenant under this Section 9.2 shall be
        paid within fifteen (15) days after Landlord has furnished Tenant with
        the statement described above.

     f. If with respect to any Operating Year or fraction thereof during the
        Term, Tenant is obligated to pay any Additional Rent as aforesaid, then

                                       28
<PAGE>

        Tenant shall pay, as Additional Rent, on the first day of each month of
        the next ensuing Operating Year, estimated monthly operating escalation
        payments in an amount from time to time reasonably estimated by Landlord
        to be sufficient to cover, in the aggregate, a sum equal to Tenant's
        Proportionate Share of the Operating Expenses in excess of the Base
        Operating Expenses for the next ensuing Operating Year. Estimated
        monthly operating escalation payments for each ensuing Operating Year
        shall be made retroactively to the first day of the Operating Year in
        question. If the estimated monthly operating escalation payments
        theretofore made such Operating Year by Tenant exceed Tenant's
        Proportionate Share of the Operating Expenses in excess of the Base
        Operating Expenses for such Operating Year according to the statement
        furnished Tenant by Landlord pursuant to paragraph (b) of this Section
        9.2, Landlord shall credit the amount of such overpayment against
        subsequent obligations of Tenant under this Lease (or refund such
        overpayment if the Term has ended and Tenant has no further obligation
        to Landlord under the Lease); but if Tenant's Proportionate Share of the
        Operating Expenses in excess of the Base Operating Expenses for said
        Operating Year is greater than the estimated monthly operating
        escalation payments theretofore made on account of such period, Tenant
        shall make suitable payment to Landlord within the time set forth in
        paragraph (e) of this Section 9.2.

     g. Tenant acknowledges that if Landlord is not furnishing any particular
        work or service, the cost of which, if performed by Landlord, would be
        included in Operating Expenses, to any tenant who has undertaken to
        perform such work or service in lieu of the performance thereof by
        Landlord, Operating Expenses shall be deemed for purposes of determining
        Operating Expenses under this Section to be increased by an amount equal
        to the additional Operating Expenses which would reasonably have been
        incurred during such period by Landlord if it had at its own expense
        furnished such work or service to such tenant.

     h. Landlord shall maintain at all times during the term of this Lease,
        complete and accurate books of account and records prepared in
        accordance with generally accepted accounting principles with respect to
        Operating Expenses and Taxes and shall retain such books and records, as
        well as contracts, bills, vouchers and checks, and such other documents
        as are reasonably necessary to properly audit the Operating Expenses and
        Taxes. Upon reasonable notice from Tenant, Landlord shall make available
        for Tenant's inspection (or inspection performed by Tenant's accountant
        and/or consultants), Landlord's books and records relating to the
        Operating Expenses and Taxes for any year. If an audit, review or
        inspection by a Tenant or Tenant's accountant or consultant alleges an
        overbilling, Tenant may submit a claim for the overbilled

                                       29
<PAGE>

        amount to Landlord detailing the nature of the overbilling, and Landlord
        shall have thirty (30) days to pay such amount or contest the claim by
        giving notice thereof to Tenant. If Landlord's statement is determined
        to be in error, Landlord shall reimburse Tenant within thirty (30) days
        following such determination for any overpayment of Operating Expenses
        or Taxes. The parties will cooperate to reach agreement or submit the
        dispute to arbitration in Boston, Massachusetts before a single
        arbitrator under the Commercial Rules of the American Arbitration
        Association who shall render a written decision with factual findings
        and conclusions which shall be final and binding upon and enforceable by
        the parties. Reference to arbitration in this Lease shall be limited
        solely to a dispute under this Section 9.2h.

                                   ARTICLE X

                    INDEMNITY AND PUBLIC LIABILITY INSURANCE

  10.1  TENANT'S INDEMNITY.  To the maximum extent this agreement may be made
effective according to law, Tenant agrees to indemnify and save harmless
Landlord from and against all claims of whatever nature arising from any act,
omission or negligence of Tenant, or Tenant's contractors, licensees, invitees,
agents, servants or employees, or arising from any accident, injury or damage
whatsoever (other than as a result of Landlord's negligence or willful
misconduct) caused to any person, or to the property of any person, occurring
after the commencement of construction work by Tenant, and until the end of the
Lease Term and thereafter, so long as Tenant is in occupancy of any part of the
Premises, within the Premises, or arising from any accident, injury or damage
occurring outside of the Premises, where such accident, damage or injury results
or is claimed to have resulted from an act or omission on the part of Tenant or
Tenant's agents, employees, independent contractors or invitees.  In case
Landlord or any other party so indemnified shall be made a party to any
litigation commenced by or against Tenant, then Tenant shall protect and hold
them harmless and shall pay all costs, expenses and reasonable attorney's fees
incurred or paid by them in connection with such litigation.

This indemnity and hold harmless agreement shall include indemnity against all
costs, expenses and liabilities incurred in or in connection with any such claim
or proceeding brought thereon, and the defense thereof. Notwithstanding any
other provisions of this Lease, the obligations of the Tenant pursuant to this
Section, shall remain in full force and effect after the termination of this
Lease until the expiration of the period stated in the applicable statute of
limitations during which a claim, cause of action or prosecution relating to the
matters herein described may be brought and the payment in full or the
satisfaction of such claim, cause of action, or

                                       30
<PAGE>

prosecution and the payment of all expenses and charges incurred by the
Landlord, or its officers, partners, employees, servants or agents, relating to
the enforcement of the provisions herein specified.

  10.  PUBLIC LIABILITY INSURANCE.  Tenant agrees to maintain in full force and
effect from the date on which Tenant first enters the Premises for any reason,
throughout the Lease Term, and thereafter so long as Tenant is in occupancy of
the Premises, a policy of Comprehensive General Liability insurance in
accordance with the broadest form of such coverage as is available from time to
time in the jurisdiction in which the Premises are located.  The minimum limits
of liability of such insurance shall be $2 million per occurrence, Bodily Injury
Liability (including death), and $500,000 pert occurrence, Property Damage
Liability, or shall be for such higher limits, if directed by Landlord, as are
customarily carried in that area in which the Building is located upon property
similar to the Building reasonably or required by any lender of Landlord at any
time during the Term or any Extended Term.  Tenant further agrees that such
insurance policy shall include Landlord as an additional named insured and shall
contain a clause that the insurer will not cancel or change the insurance
without first giving Landlord thirty (30 days' prior written notice.
Furthermore, Tenant shall deliver to Landlord or its designated management
company a copy of the policy or a certificate of insurance showing Landlord as
named additional insured

  The policy shall also include, but shall not be limited to, the following
extensions of coverage:

          a. Contractual Liability, covering Tenant's liability assumed under
             this Lease:

          b. Personal Injury Liability in the amount of $2 million annual
             aggregate, expressly deleting the exclusion relation to contractual
             assumptions of liability;

          c. Civil Assault and Battery Coverage.

Tenant further agrees to maintain a Workers' Compensation and Employers'
Liability Insurance Policy. The limit of liability as respects Employers'
Liability coverage shall be no less than $100,00 per accident.

Except for Workers' Compensation and Employers' Liability coverage, Tenant
agrees that Landlord (and such other persons as are in privity of estate with
Landlord as may be set out in notice from time to time) shall be named as
additional insureds. Further, all policies shall be noncancelable and
nonamendable with respect to Landlord and Landlord's said designees without
thirty (30) days' prior written notice to Landlord. A Certificate of Insurance

                                       31
<PAGE>

evidencing the above agreements shall be delivered to Landlord upon the
execution of this lease and, in each instance, as and when amended, extended,
renewed or replaced. A duplicate original, true copy, certified in writing to be
so shall be given to Landlord upon request.

  10.3  TENANT'S RISK.  To the maximum extent this agreement may be made
effective according to law, Tenant agrees to use and occupy the Premises and to
use such other portions of the Building as Tenant is herein given the right to
use at Tenant's own risk; and Landlord shall have no responsibility or liability
for any loss of or damage to fixtures or other personal property of Tenant for
any reason whatsoever other than due to Landlord's negligence or willful
misconduct.  The provisions of this Section shall be applicable from and after
the execution of this Lease and until the end of the Lease Term, and during such
further period as Tenant may use or be in occupancy of any part of the Premises
or of the Building.

  10.4  INJURY CAUSED BY THIRD PARTIES. To the maximum extent this agreement may
be made effective according to law, Tenant agrees that Landlord shall not be
responsible or liable to Tenant, or to those claiming by, through or under
Tenant, for any loss or damage that may be occasioned by or through the acts or
omissions of persons occupying adjoining premises or any part of the premises
adjacent to or connecting with the Premises or any part of the Building, or
otherwise or for any loss or damage resulting to Tenant or those claiming by,
through or under Tenant, or its or their property, from latent defects, the
breaking, bursting, stopping or leaking of electric cables and wires, water,
gas, sewer or steam pipes, and from roof leaks and the like unless caused by
Landlord's negligence or willful misconduct.

  10.5  FIRE AND HAZARD INSURANCE.  The Landlord shall keep the Premises insured
against loss or damage by fire, with the usual extended coverage endorsements
and such other insurance as the then holder of any first mortgage which includes
the Premises shall require, in amounts not less than eighty percent (80%) of the
full replacement value thereof above foundation walls, with such deductibles as
the Landlord deems advisable, but specifically excluding any property or
improvements installed by or belonging to the Tenant.

  10.6  ADDITIONAL INSURANCE.  The Tenant also agrees that it shall continuously
keep its fixtures, merchandise (if any), equipment and other personal property
from time to time located in, on or about the Premises, and all leasehold
improvements to the Premises constructed or installed by the Tenant insured by
reputable, duly licensed insurance companies against loss or damage by fire with
the usual extended coverage endorsements.  Within a reasonable time after the
Lease Commencement Date, no less often than annually thereafter, and at any
other time upon the reasonable request of the Landlord, the Tenant

                                       32
<PAGE>

shall furnish to the Landlord evidence of such continuous insurance coverage
reasonably satisfactory to the Landlord. It is understood and agreed that the
Tenant assumes all risk of damage to its own property arising from any cause
whatsoever, including, without limitation, loss by theft or otherwise, unless
caused by Landlord's negligence or willful misconduct.

  10.7  ADDITIONAL RESTRICTIONS.  Tenant further agrees that it will not keep,
use, sell or offer for sale in or about the Premises, any article which may be
prohibited by Landlord's or Tenant's fire insurance policy then in effect
covering the Premises and/or the Building or any of its contents.  In the event
that Tenants occupancy causes any increases of premium of the fire and/or
casualty insurance policy covering the Building or any part thereof above the
rate for an office building, Tenant shall pay the additional premium on the fire
and/or casualty insurance policy by reason thereof.

                                  ARTICLE XI

                         LANDLORD'S ACCESS TO PREMISES

  11.1  LANDLORD'S RIGHT OF ACCESS.  Landlord shall have the right, upon
reasonable notice to Tenant, except in the event of an emergency, to enter the
Premises at all reasonable business hours and after normal business hours for
the purpose of inspecting or making repairs to the same, and Landlord shall also
have the right to make access available upon reasonable notice to the Tenant,
except in the event of an emergency, at all reasonable hours to prospective or
existing mortgagees or purchasers of any part of the Building.

  11.2  EXHIBITION OF SPACE TO PROSPECTIVE TENANTS.  For a period of nine (9)
months prior to the expiration of the Lease Term, Landlord may have reasonable
access to the Premises at all reasonable hours for the purpose of exhibiting,
the same to prospective tenants, and may post suitable notice on the Premises
advertising the same for rent.

                                  ARTICLE XII

                             DAMAGE AND DESTRUCTION

  12.1  NOTICE.  Tenant shall give prompt notice to Landlord in case of fire or
accidents in the Premises or of defects therein or in any fixtures or equipment.
However, such notices, or any occurrence giving rise thereto, shall not impose
any duty on Landlord except as otherwise expressly provided herein.

If the Premises or the Building, are damaged by fire or other insured casualty,
Landlord will give Tenant notice of the number of days Landlord expects will be
needed to repair such damage, as determined by Landlord, and the election

                                       33
<PAGE>

(if any) which Landlord has made according to this Article XII. Such notice will
be given on or before the thirtieth (30th) day (the "Notice Date") after the
fire or other insured casualty.

  12.2  DESTRUCTION OF BUILDING OR PREMISES. If the Premises or the Building are
damaged by fire or other insured casualty to an extent which may be repaired
within one hundred twenty (120) days after the Notice Date, Landlord will repair
the damage with reasonable diligence, and will use reasonable diligence to do so
within one hundred twenty (120) days after the Notice Date.  Landlord reserves
the right to extend such date for completion of said repairs for one (1) thirty
(30) day extension if the Landlord is diligently pursuing repairs to the
Building or Premises and is unable to complete said repairs within one hundred
twenty (120) days.  If, at the expiration of the thirty (30) day extension
Landlord has not completed the necessary repairs, then Landlord will advise
Tenant in writing of the time needed to complete said repairs.  Tenant shall
have the option to terminate by giving written notice to Landlord, within seven
(7) days of the end of the extension period, of its intention to terminate.  If
Tenant does not terminate in accordance with the process hereinbefore set forth,
then Tenant shall have waived its right to terminate this Lease under this
Section 12.2.  In that event, this Lease will continue in full force and effect
except that Rent will be abated on a pro rata basis based on the rentable area
of the Premises of which use Tenant is deprived during the Repair Period from
the date of the fire or other insured casualty until the date that the Landlord
shall have substantially restored the Building and/or Premises (exclusive of any
of Tenant's fixtures, furnishings, equipment and the like or work performed
therein by Tenants) to substantially the condition in which the Building and/or
Premises were in prior to such damage (the "Repair Period").

If the Premises or the Building are damaged by fire or other insured casualty to
an extent which may not be repaired within one hundred twenty (120) days after
the Notice Date but may be repaired within one hundred fifty (150) days after
the Notice Date, then, at Landlord's option, Landlord will repair such damage
with reasonable diligence, and in all events within one hundred fifty (150) days
after the Notice Date. Landlord reserves the right to extend the date for
completion of said repairs for one (1) thirty (30) day extension if the Landlord
is diligently pursuing repairs to the Building or Premises and is unable to
complete said repairs within one fifty (50) days. If, at the expiration of the
thirty (30) day extension Landlord has not completed the necessary repairs, then
Landlord will advise Tenant in writing of the time needed to complete said
repairs. Tenant shall have the option to terminate by giving written notice to
Landlord within seven (7) days of the end of the extension period of its
intention to terminate. If Tenant does not terminate in accordance with the
process hereinbefore set forth, then Tenant shall have waived its right to
terminate this Lease under this Section 12.2. If Landlord elects to repair

                                       34
<PAGE>

such damage, Rent will be abated on a pro rata basis during the Repair Period
based on the rentable area of the Premises of which Tenant is deprived during
the Repair Period. If Landlord does not elect to repair such damage, this Lease
will terminate on the Notice Date, and Rent will be abated on a pro rata basis
based on the rentable area of the Premises of which use Tenant is deprived
during the Repair Period from the date of the fire or other insured casualty
until the Notice Date based on the usable area of the Premises of which use
Tenant is deprived until the Notice Date.

If the Premises or the Building are damaged by fire or other insured casualty to
an extent which may not be repaired within one hundred fifty (150) days after
the commencement of repair, as reasonably determined by Landlord, then (i)
Landlord may cancel this Lease as of the date of such damage by written notice
given to Tenant on or before the Notice Date, or (ii) Tenant may cancel this
Lease by written notice given to Landlord within ten (10) days after Landlord's
delivery of a notice that the repairs cannot be made within such one hundred
fifty (150) day period. If neither Landlord nor Tenant so elects to cancel this
Lease within the prescribed periods, Landlord will repair the Building and
Premises with reasonable diligence and Rent will be abated on a pro rata basis
during the Repair Period based on the rentable area of the Premises of which use
Tenant is deprived during the Repair Period. So long as Landlord is making
diligent efforts to make said repairs to the Building and/or Premises, Landlord
may extend the date for completion of the necessary repairs for one (1) thirty
(30) day extension period. If, at the expiration of the thirty (30) day
extension Landlord has not completed the necessary repairs, then Landlord will
advise Tenant in writing of the time needed to complete said repairs. Tenant
shall have the option to terminate by giving written notice to Landlord within
seven (7) days of the end of the extension period of its intention to terminate.
If Tenant does not terminate in accordance with the process hereinbefore set
forth, then Tenant shall have waived its right to terminate this Lease under
this Section 12.2.

If the Premises or the Building are damaged by any uninsured casualty, Landlord
will have the option to repair such damage with reasonable diligence or cancel
this Lease as of the date of such casualty by written notice to the Tenant on or
before the Notice Date. If Landlord elects to repair such damage, Rent will be
abated on a pro rata basis from the date of the uninsured casualty until the
repair of such damage is completed based on the Rentable area of the Premises of
which Tenant is deprived during such Repair Period. If, pursuant to the
reasonable estimation of Tenant, the repairs elected to be performed by Landlord
pursuant to this Section 12.2 of this Article XII will exceed one hundred fifty
(150) days, then Tenant will have the right to terminate this Lease as of the
Notice Date. If Tenant so elects to terminate this Lease, Rent will be abated on
a pro rata basis from the uninsured casualty until the Notice Date based on the
Rentable area of Premises of which use Tenant is deprived

                                       35
<PAGE>

until the Notice Date. If any such damage by fire or other casualty is the
result of the willful conduct or negligence or failure to act of Tenant, its
agents, contractors, employees or invitees, there will be no abatement of Rent
as otherwise provided for in this Article XII.

In the event Landlord, in its sole judgment, determines that restoration of the
entire Building or Premises is not practical, Landlord will give notice to
Tenant on or prior to the Notice Date of said casualty which notice shall
specify Landlord's intent not to repair the Building or Premises and this Lease
will terminate on the Notice Date, and Rent will be abated on a pro rata basis
from the date of the fire or other insured casualty until the Notice Date based
on the rentable area of the Premises of which use Tenant is deprived until the
Notice Date.

In no event shall Landlord be obligated in connection with the restoration of
the Premises, as aforesaid, to expend an amount in excess of the proceeds of
insurance recovered with respect thereto. In the event the Premises shall be
damaged by fire or other casualty resulting from the act or neglect of Tenant,
its agents, contractors, employees or invitees, and this Lease shall not be
terminated by Landlord as a result of such damage, Tenant shall not be released
from any of its obligations hereunder including, without limitation, its duty to
pay the Annual Base Rent and the Additional Rent payable by Tenant under Article
VIII hereof without abatement or reduction.

                                 ARTICLE XIII

                                EMINENT DOMAIN

  13.1  GENERAL.  If all or substantially all of a portion ["substantially all"
hereby defined to mean fifty-one percent (51 %) or more of the rentable area] of
the Premises are taken by exercise of the power of eminent domain (or conveyed
by Landlord in lieu of such exercise), this Lease will terminate on a date (the
"Termination Date") which is the earlier of the date upon which the condemning
authority takes possession of the Premises or the date on which title to the
Premises is vested in the condemning authority, and from and after the
Termination Date, Tenant's obligation to pay rent under this Lease will cease.

If less than a substantial portion of the Premises is so taken, but such taking
is of at least one third (1/3) of the rentable area of the Premises, Tenant will
have the right to cancel this Lease by written notice to Landlord given within
twenty (20) days after the Termination Date. If all or substantially all of the
Project is so taken, Landlord may cancel this Lease by written notice to Tenant
given within thirty (30) days after the termination date. In the event of any
such taking, the entire award will be paid to Landlord and Tenant will have

                                       36
<PAGE>

no right or claim to any part of such award; provided, however, that Tenant will
have a right to assert a claim against the condemning authority in a separate
action for Tenant's relocation expenses and so long as Landlord's award is not
reduced by such claim. The termination of this Lease pursuant to this Article
XIII will not affect the rights of either Landlord or Tenant to such awards.

In the event that less than all or substantially all of the Premises are taken
by exercise of the power of eminent domain and, if 13.2 is applicable, Tenant
shall not have exercised its right to terminate thereunder, and in the
Landlord's sole determination it is practical to repair the remaining Premises
for occupancy by Tenant, including parking areas necessary for occupancy by the
Tenant as provided herein, Landlord shall notify Tenant within thirty (30) days
of the Termination Date of the extent of the Premises to remain subject to this
Lease and shall within one hundred fifty (150) days following said notice to
Tenant complete any repairs or restoration determined necessary by Landlord. The
Annual Base Rent and Additional Rent shall abate to the extent of reduction of
the Premises due to the taking and during the time a portion, if any, of the
remaining Premises are rendered untenantable, in such proportion as the portion
rendered untenable bears to the total.

If the taking agency takes only the right to possession of the Premises for a
fixed period of time or for the duration of an emergency or other temporary
condition (in any case, not to exceed six (6) months), then, notwithstanding
anything above provided, this Lease shall continue in full force and effect and
Annual Base Rent and Additional Rent shall be abated based on the extent and
term the Premises or any part thereof shall be unavailable.

  13.2  AWARD.  Landlord shall have and hereby reserves and accepts, and Tenant
hereby grants and assigns to Landlord, all rights to recover for damages to the
Building, the Land, and the leasehold interest hereby created, and to
compensation accrued or hereafter to accrue by reason of such taking, damage or
destruction, as aforesaid, and by way of confirming the foregoing, Tenant hereby
grants and assigns, and covenants with Landlord to grant and assign to Landlord
all rights to such damages or compensation.  Nothing contained herein shall be
construed to prevent Tenant from prosecuting in any condemnation proceedings a
claim for the value of any Tenant's usual trade fixtures installed in the
Premises by Tenant at Tenant's expense and for relocation expenses, provided
that such action shall not affect the amount of compensation otherwise
recoverable by Landlord from the taking authority.

                                  ARTICLE XIV

                              LANDLORD'S REMEDIES

  14.1 EVENTS OF DEFAULT.  Any one of the following shall be deemed to be an
"Event of Default":

     a. Failure on the part of Tenant to pay Annual Base Rent, Additional Rent
        or other charges for which provision is made herein on or before the
        date on which the same become due and payable and such failure continues
        for ten (10) days after Landlord has sent to Tenant notice of such
        default.

        However, if: (i) Landlord shall have sent to Tenant two (2) notices of
        such default, even though the same shall have been cured and this Lease
        not terminated; and (ii) during the twelve (12) month period in which
        said notice of default has been sent by Landlord to Tenant, Tenant
        thereafter shall default in any monetary payment - the same shall be
        deemed to be an Event of Default upon Landlord giving Tenant written
        notice thereof, without the ten (10) day grace period set forth above.

     b. With respect to a non-monetary default under this Lease, failure of
        Tenant to cure the same within thirty (30) days following notice from
        Landlord to Tenant of such default unless such default is not reasonably
        capable of being cured within such thirty (30) day period, in which
        event Tenant will not be in default so long as Tenant promptly commences
        to cure such failure and thereafter diligently prosecutes such cure to
        completion. Notwithstanding the thirty (30) day cure period provided in
        the preceding sentence, Tenant shall be obligated to commence forthwith
        and to complete as soon as possible the curing of such default; and if
        Tenant fails so to do, the same shall be deemed to be an Event of
        Default.

        However, if: (i) Landlord shall have sent to Tenant two (2) notices of
        such default, even though the same shall have been cured and this Lease
        not terminated; and (ii) during the twelve (12) month period in which
        said notice of default has been sent by Landlord to Tenant, Tenant
        thereafter shall default in such non-monetary matter - the same shall be
        deemed to be an Event of Default upon Landlord giving the Tenant written
        notice thereof, and Tenant shall have no grace period within which to
        cure the same.

                                       38
<PAGE>

     c. The occurrence of any of the following events: (i) the estate hereby
        created being taken on execution or by attachment or trustee process or
        other process of law and not dismissed within sixty (60) days; (ii) the
        filing by Tenant being judicially declared bankrupt or insolvent
        according to law; (iii) an assignment being made of the property of
        Tenant for the benefit of creditors; (iv) a receiver, guardian,
        conservator, trustee in involuntary bankruptcy or other similar officer
        being appointed to take charge of all or any substantial part of
        Tenant's property by a court of competent jurisdiction; (v) a petition
        being filed by Tenant for the reorganization of Tenant or under any
        other chapter or provisions of the Bankruptcy Act now or hereafter
        enacted; or (vi) an involuntary petition under the Bankruptcy Act filed
        which shall not have been dismissed within sixty (60) days.

     d. Execution by Tenant of an instrument purporting to assign Tenant's
        interest under this Lease or sublet the whole or a portion of the
        Premises to a third party without Tenant having first obtained
        Landlord's prior express written consent to said assignment or
        subletting.

  14.2  REMEDIES.  Should any Event of Default occur then, notwithstanding any
license of any former breach of covenant or waiver of the benefit thereof or
consent in a former instance, Landlord lawfully, in addition to any remedies
otherwise available to Landlord, immediately or at any time thereafter, and
without demand or notice, may enter into and upon the Premises or any part
thereof in the name of the whole and repossess the same as of Landlord's former
estate, and expel Tenant and those claiming, by, through or under it and remove
its or their effects (forcibly if necessary) without being deemed guilty of any
manner of trespass, and without prejudice to any remedies which might otherwise
be used for arrears of rent or preceding breach of covenant and/or Landlord may
send notice to Tenant terminating the Term of this Lease; and upon the first to
occur of:  (i) entry as aforesaid; or (ii) the fifth (5th) day following the
mailing of such notice of termination, the Term of this Lease shall terminate,
but Tenant shall remain liable for all damages as provided for herein.

  14.3  TENANT'S OBLIGATIONS/LANDLORD'S RIGHTS.  Tenant covenants and agrees,
notwithstanding any termination of this Lease as aforesaid or any entry or re-
entry by Landlord, whether by summary proceedings, termination, or otherwise, to
pay and be liable for on the days originally fixed herein for the payment
thereof, amounts equal to the several installments of Annual Base Rent and other
charges reserved as they would become due under the terms of this Lease if this
Lease had not been terminated or if Landlord had not entered or re-entered, as
aforesaid, and whether the Premises be relet or remain vacant, in whole or in
part, or for a period less than the remainder of the Term, or for

                                       39
<PAGE>

the whole thereof; but in the event the Premises be relet by Landlord, Tenant
shall be entitled to a credit in the net amount of rent received by Landlord in
reletting, after deduction of all reasonable expenses incurred in reletting the
Premises (including, without limitation, remodeling costs, brokerage fees,
attorneys' fees and the like), and in collecting the rent in connection
therewith. It is specifically understood and agreed that Landlord shall be
entitled to take into account in connection with any reletting of the Premises
all relevant factors which would be taken into account by a sophisticated
developer in securing a replacement tenant for the Premises, such as, but not
limited to, the first class quality of the Building and the financial
responsibility of any such replacement tenant. Landlord agrees to use reasonable
efforts to mitigate its damages in the Event of Default on the part of the
Tenant. Landlord will not be required to place special emphasis on the Premises
in any reletting program or to lease the Premises prior to leasing any other
space in the Building. As an alternative, at the election of Landlord at any
time, including after the Landlord has instituted reletting or the monthly
collection of Tenant's installments of Annual Base Rent and other charges as
provided under this Lease, Tenant will upon such termination pay to Landlord, as
damages, such a sum as at the time of such termination represents the amount of
the excess, if any, of the present value (calculated at the prime rate) of the
total rent and other benefits which would have accrued to Landlord under this
Lease for the remainder of the Lease Term if the lease terms had been fully
complied with by Tenant over and above the then cash rental value (in advance)
of the Premises for the balance of the Term. For purposes of this Article, if
Landlord elects to require Tenant to pay damages in accordance with immediately
preceding sentence, the total rent shall be computed by assuming that Tenant's
Proportionate Share of Taxes in excess of the Base Tax Amount and Tenant's
Proportionate Share of the Operating Expenses in excess of the Base Operating
Expenses would be, for the balance of the unexpired term, the amount thereof (if
any), respectively, for the immediately preceding Tax Period or fiscal year, as
the case may be, payable by Tenant to Landlord. All calculations necessary to
determine the amounts due from Tenant to Landlord shall be performed by Landlord
and may be amended by Landlord for error or incompleteness. The computations
shall relate to all periods of time, including prior periods in which Tenant
shall not have made payments of Annual Base Rent and other charges as provided
under this Lease and shall be binding upon Tenant in all respects absent
manifest error.

If this Lease shall be guaranteed on behalf of Tenant, all of the foregoing
provisions of this Article with respect to insolvency, assignment for the
benefit of creditors, bankruptcy of Tenant, etc., shall be deemed to read
"Tenant or the guarantor hereof.

In the event of any breach or threatened breach by Tenant of any of the
agreements, terms, covenants or conditions contained in this Lease, Landlord

                                       40
<PAGE>

shall be entitled to enjoin such breach or threatened breach and shall have the
right to invoke any right or remedy allowed at law or in equity or by statute or
otherwise as though reentry, summary proceedings, and other remedies were not
provided for in this Lease.

Each right and remedy of Landlord provided for in this Lease shall be cumulative
and shall be in addition to every other right or remedy provided for in this
Lease not now or hereafter existing at law or in equity or by statute or
otherwise, and the exercise or beginning of the exercise by Landlord of any one
or more of the rights or remedies provided for in this Lease or now or hereafter
existing at law or in equity or by statute or otherwise shall not preclude the
simultaneous or later exercise by Landlord of any or all other rights or
remedies provided for in this Lease or now or hereafter existing at law or in
equity or by statute or otherwise.

If any payment of rent or any other payment payable hereunder by Tenant to
Landlord shall not be paid when due, the same shall bear interest from the date
when the same was payable until the date paid at the lesser of (a) eighteen
percent (18%) per annum, compounded monthly, or (b) the highest lawful rate of
interest which Landlord may charge to Tenant without violating any applicable
law. Such interest shall constitute Additional Rent payable hereunder and be
payable upon demand therefor by Landlord.

Without limiting any of Landlord's rights and remedies hereunder, and in
addition to all other amounts Tenant is otherwise obligated to pay, it is
expressly agreed that Landlord shall be entitled to recover from Tenant all
costs and reasonable expenses, including reasonable attorneys' fees incurred by
Landlord in enforcing this Lease from and after Tenant's default.

  14.4  LANDLORD'S DEFAULT.  Landlord shall in no event be in default in the
performance of any of Landlord's obligations hereunder unless and until Landlord
shall have failed to perform such obligations within thirty (30) days, or such
additional time as is reasonably required to correct any such default, after
written notice by Tenant to Landlord properly specifying wherein Landlord has
failed to perform any such obligation

                                  ARTICLE XV

                            MISCELLANEOUS PROVISIONS

  15.1  EXTRA HAZARDOUS USE. Tenant covenants and agrees that Tenant will not do
or permit anything to be done in or upon the Premises, or bring in anything or
keep anything therein which shall increase the rate of insurance on the Premises
or on the Building above the standard rate applicable to premises being occupied
for the use to which Tenant has agreed to devote the Premises;

                                       41
<PAGE>

and Tenant further agrees that in the event that Tenant shall do any of the
foregoing, Tenant will promptly pay to Landlord, on demand, any such increase
resulting therefrom which shall be due and payable as Additional Rent hereunder.

  15.2  WAIVER.  Failure on the part of Landlord or Tenant to complain of any
action or nonaction on the part of the other, no matter how long the same may
continue, shall never be a waiver by Tenant or Landlord, respectively, of any of
their fights hereunder.  Further, no waiver at any time of any of the provisions
hereof by Landlord or Tenant shall be construed as a waiver of any of the other
provisions hereof, and a waiver at any time of any of the provisions hereof
shall not be construed as a waiver at any subsequent time of the same
provisions.  The consent or approval of Landlord or Tenant to or of any action
by the other requiring such consent or approval shall not be construed to waive
or render unnecessary Landlord's or Tenant's consent or approval to or of any
subsequent similar act by the other.

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

  15.3  COVENANT OF QUIET ENJOYMENT. Tenant, subject to the terms and provisions
of this Lease, upon payment of the Annual Base Rent and other charges due
hereunder and the observing, keeping and performing of all of the terms and
provisions of this Lease on Tenant's part to be observed, kept and performed,
shall lawfully, peaceably and quietly have, hold, occupy and enjoy the Premises
during the Term hereof, without hindrance or ejection by any persons lawfully
claiming under Landlord to have title to the Premises superior to Tenant; the
foregoing covenant of quiet enjoyment is in lieu of any other covenant,
expressed or implied; and it is understood and agreed that this covenant and any
and all other covenants of Landlord contained in this Lease shall be binding
upon Landlord and Landlord's successors only with respect to breaches occurring
during Landlord's and Landlord's successors' respective ownership of Landlord's
interest hereunder.  Further, Tenant specifically agrees to look solely to
Landlord's then equity interest in the Building and Land at the time owned, or
in which Landlord holds an interest as ground lessee, for recovery of any
judgment from Landlord; it being specifically agreed that Landlord (original or
successor), its employees, officers, directors, managers,

                                       42
<PAGE>

shareholders, equity holders, agents, managers and attorneys and their
respective successors and assigns ("additional persons") shall never be
personally liable for any such obligations or judgment, or for the payment of
any monetary obligation to Tenant. The provision contained in the foregoing
sentence is not intended to, and shall not limit any right that Tenant might
otherwise have to obtain injunctive relief against Landlord or Landlord's
successors in interest, or any action not involving the personal liability of
Landlord (original or successor) and the additional persons to respond in
monetary damages from Landlord's assets other than Landlord's equity interest
aforesaid in the Building and Land. With respect to any services, including,
without limitation, heat, air-conditioning or water to be furnished by Landlord
to Tenant, or obligations to be performed by Landlord hereunder, Landlord shall
in no event be liable for failure to furnish or perform the same when (and the
date for performance of the same shall be postponed so long as Landlord is)
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 perform such obligations 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 Tenant's
servants, agents, employees, licensees, invitees or any person claiming by,
through or under Tenant. In the event of an interruption of services to the
Premises, if Tenant provides Landlord notice describing such interruption and if
such interruption is (i) not due to any act or omission of Tenant or any agent,
contractor, employee or invitee of Tenant; and (ii) of such substantial or
serious nature that the Premises are rendered unusable by Tenant as a result
thereof for more than five (5) business days after Landlord's receipt of such
notice, the Annual Base Rent shall be equitably abated as of the fifth (5th)
business day. In no event shall Landlord ever be liable to Tenant for any
indirect, special or consequential damages suffered by Tenant from whatever
cause.

  15.4  NOTICE TO MORTGAGEE AND GROUND LESSOR.  After receiving notice from any
person, firm or other entity that it holds a mortgage which includes the
Premises as part of the mortgaged premises, or that it is the ground lessor
under a lease with Landlord, as ground lessee, which includes the Premises as
part of the demised premises, no notice from Tenant to Landlord shall be
effective unless and until a copy of the same is given to such holder or ground
lessor, and the curing of any of Landlord's defaults by such holder or ground
lessor shall be treated as performance by Landlord.  For the purposes of this
Section 15.4, Section 15.5 or Section 15.14, the term "mortgage" includes a
mortgage on a leasehold interest of Landlord (but not one on Tenant's leasehold
interest).

                                       43
<PAGE>

  15.5  ASSIGNMENT OF LEASES AND RENTS.  With reference to any assignment by
Landlord of Landlord's interest in this Lease, or the rents payable hereunder,
conditional in nature or otherwise, which assignment is made to the holder of a
mortgage or ground lease on property which includes the Premises.  Tenant
agrees:

     a. that the execution thereof by Landlord, and the acceptance thereof by
        the holder of such mortgage, or the ground lessor, shall never be
        treated as an assumption by such holder or ground lessor of any of the
        obligations of Landlord hereunder, unless such holder or ground lessor
        shall, by notice sent to Tenant, specifically otherwise elect; and

     b. that, except as aforesaid, such holder or ground lessor shall be treated
        as having assumed Landlord's obligations hereunder only upon foreclosure
        of such holder's mortgage and the taking of possession of the Premises,
        or in the case of a ground lessor, the assumption of Landlord's position
        hereunder by such ground lessor. In no event shall the acquisition of
        title to the Building and the Land or a portion thereof on which the
        Building is located by a purchaser which, simultaneously therewith,
        leases the entire Building or such land back to the seller thereof, be
        treated as an assumption by operation of law or otherwise of Landlord's
        obligations hereunder, but Tenant shall look solely to such seller-
        lessee, and its successors from time to time in title, for performance
        of Landlord's obligations hereunder. In any such event, this Lease shall
        be subject and subordinate to the lease to such seller. For all purposes
        such seller-lessee, and its successors in title, shall be the landlord
        hereunder unless and until Landlord's position shall have been assumed
        by such purchaser-lessor.

  15.6  MECHANIC'S LIENS.  Tenant agrees immediately to discharge (either by
payment or by the filing of the necessary bond, or otherwise) any mechanics',
materialmen's or other lien against the Premises and/or Landlord's interest
therein, which liens may arise out of any payment due for, or purported to be
due for, any labor, services, materials, supplies or equipment alleged to have
been furnished to or for Tenant in, upon or about the Premises.

  15.7  NO BROKERAGE.  Landlord and Tenant each warrants and represents that it
has dealt with no other broker in connection with the consummation of this
Lease, other than Neelon ("Tenant's Broker") and Fallon, Hines & O'Connor
("Landlord's Broker"), and in the event of any brokerage claims, other than by
Neelon or Fallon, Hines & O'Connor, predicated upon prior dealing with Landlord
or Tenant, the party breaching such warranties agrees to defend the same and
indemnify and hold harmless the non-breaching party against any such claims and
the costs and expenses, including attorneys' fees, arising

                                       44
<PAGE>

therefrom. Landlord shall pay the commission due to Tenant's broker and
Landlord's broker.

  15.8  INVALIDITY OF PARTICULAR PROVISIONS.  If any term or provision of this
Lease or the application thereof to any person or circumstance shall, to any
extent, be invalid or unenforceable, the remainder of this Lease, or the
application of such term or provision to persons or circumstances other than
those as to which it is held invalid or unenforceable, shall not be affected
thereby, and each term and provision of this Lease shall be valid and
enforceable to the fullest extent permitted by law.

  15.9  PROVISIONS BINDING, ETC.  Except as herein otherwise provided, the terms
hereof shall be binding upon and shall inure to the benefit of the successors
and assigns, respectively, of Landlord and Tenant and, if Tenant shall be an
individual, upon and to his heirs, executors, administrators, successors and
assigns.  If two or more persons are named as Tenant herein, each of such
persons shall be jointly and severally liable for the obligations of the Tenant
hereunder, and Landlord may proceed against any one without first having
commenced proceedings against any other of them.  Each term and each provision
of this Lease to be performed by Tenant shall be construed to be both a covenant
and a condition.  The reference contained to successors and assigns of Tenant is
not intended to constitute a consent to assignment by Tenant, but has reference
only to those instances in which Landlord may later give consent to a particular
assignment as required by those provisions of Article V hereof.

  15.10  RECORDING. Tenant agrees not to record the within Lease, but each party
hereto agrees, on the request of the other, to execute a so-called memorandum of
lease or short form lease in form recordable and complying with applicable law
and reasonably satisfactory to Landlord's attorneys.  In no event shall such
document set forth the rent or other charges payable by Tenant under this Lease;
and any such document shall expressly state that it is executed pursuant to the
provisions contained in this Lease and is not intended to vary the terms and
conditions of this Lease.

  15.11  NOTICES.  Whenever, by the terms of this Lease, notice shall or may be
given either to Landlord or to Tenant, such notice shall be in writing and shall
be delivered in hand or sent by registered or certified mail, postage prepaid or
nationally recognized, receipted, overnight delivery service or facsimile
transmission followed by an original writing delivered, mailed or sent as
aforesaid:

If intended for Landlord, addressed to Landlord at the address set forth in
Section 1.2 of this Lease (or to such other address or addresses as may from
time to time hereafter be designated by Landlord by like notice) and a copy to

                                       45
<PAGE>

Roche, Carens & DeGiacomo, P.C., 99 High Street, 20th Floor, Boston,
Massachusetts 02110, Attention Frank M. Capezzera.

If intended for Tenant, addressed to Tenant at the address set forth in Section
1.2 of this Lease (or to such other address or addresses as may from time to
time hereafter be designated by Tenant by like notice) and a copy to Hale and
Dorr, LLP, 60 State Street, Boston, MA 02109, Attn: Jeffrey A. Hermanson.

All such notices shall be effective when delivered in hand, or when deposited in
the United States mail within the continental United States provided that the
same are received in the ordinary course at the address to which the same were
sent. Any party or person entitled to notice may change the address therefor
giving notice to all parties or persons as provided herein.

  15.12  WHEN LEASE BECOMES BINDING.  Employees or agents of Landlord have no
authority to make or agree to make a lease or any other agreement or undertaking
in connection herewith.  The submission of this document for examination and
negotiation does not constitute an offer to lease, or a reservation of, or
option for, the Premises, and this document shall become effective and binding
only upon the execution and delivery hereof by both Landlord and Tenant.  All
negotiations, considerations, representations and understandings between
Landlord and Tenant are incorporated herein and may be modified or altered only
by written agreement between Landlord and Tenant, and no act or omission of any
employee or agent of Landlord shall alter, change or modify any of the
provisions hereof

  15.13  PARAGRAPH HEADINGS.  The paragraph headings throughout this instrument
are for convenience and reference only, and the words contained therein shall in
no way be held to explain, modify, amplify or aid in the interpretation,
construction or meaning of the provisions of this Lease.

  15.14  RIGHTS OF MORTGAGEE.  It is understood and agreed that the rights and
interests of Tenant under this Lease shall be subject and subordinate to any
mortgages or deeds of trust that may hereafter be placed upon the Building
and/or the Land, and to any and all advances to be made thereunder, and to the
interest thereon, and all renewals, modifications, replacements and extensions
thereof, if the mortgagee or trustee named in said mortgages or deeds of trust
shall elect by notice delivered to Tenant to subject and subordinate the rights
and interest of Tenant under this Lease to the lien of its mortgage or deed of
trust; it is further agreed that any mortgagee or trustee may elect to give the
rights and interest of Tenant under this Lease priority over the lien of its
mortgage or deed of trust.  In the event of either such election, and upon
notification by such mortgagee or trustee to Tenant to that effect, the rights
and interest of Tenant under this Lease shall be deemed to be subordinate to, or
to have priority over, as the case may be, the lien of said

                                       46
<PAGE>

mortgage or deed of trust, whether this Lease is dated prior to or subsequent to
the date of said mortgage or deed of trust. Tenant shall execute and deliver
whatever instruments may be required for such purposes, and in the event Tenant
fails so to do within ten (10) days after demand in writing, Tenant does hereby
make, constitute and irrevocably appoint Landlord as its attorney-in-fact
coupled with an interest and given as security and in its name, place and stead
so to do. In the event that any holder or prospective holder of any mortgage
which includes the Premises as part of the mortgaged premises, shall request any
modification of any of the provisions of this Lease, other than a provision
directly related to the rents payable hereunder, the duration of the term
hereof, or the size, use or location of the Premises, or Tenant's subletting and
assignment rights, Tenant agrees that Tenant will enter into a written agreement
in recordable form with Landlord or 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 for all purposes. Tenant hereby appoints such holder as
Tenant's attorney-in-fact as aforesaid to execute any such modification upon
default of Tenant in complying with such holder's request.

  15.15  STATUS REPORT.  Recognizing that both parties may find it necessary to
establish to third parties, such as accountants, banks, mortgagees or the like,
the then current status of performance hereunder, either party, on the request
of the other made from time to time, will promptly furnish to Landlord, or the
holder of any mortgage encumbering the Premises, or to Tenant, as the case may
be, a statement of the status of any matter pertaining to this Lease, including,
without limitation, acknowledgments that (or the extent to which) each party is
in compliance with its obligations under the terms of this Lease.

  15.16  SECURITY DEPOSIT; TENANT'S FINANCIAL CONDITION.  If, in Section 1.2
hereof, a security deposit is specified, Tenant agrees that the same will be
paid upon execution and delivery of this Lease, and that Landlord shall hold the
same, throughout the term of this Lease, as security for the performance by
Tenant of all obligations on the part of Tenant to be kept and performed.
Landlord shall have the right from time to time without prejudice to any other
remedy Landlord may have on account thereof, to apply such deposit, or any part
thereof, to Landlord's damages arising from any default on the part of Tenant.
Tenant not then being in default, Landlord shall return the deposit, or so much
thereof as shall not have theretofore been applied in accordance with the terms
of this Section 15.16 to Tenant on the expiration or earlier termination of the
Lease Term and surrender of possession of the Premises by Tenant to Landlord at
such time.  While Landlord holds such deposit, Landlord shall pay interest on
the same and shall keep said deposit in a separate account.  If Landlord conveys
Landlord's interest under this Lease, the deposit or any part thereof, including
the interest, not previously applied may

                                       47
<PAGE>

be turned over by Landlord to Landlord's grantee, and if so turned over, Tenant
agrees to look solely to such grantee for proper application of the deposit in
accordance with the terms of this Section 15.16 and the return thereof in
accordance herewith.

Neither the holder of a mortgage nor the lessor in a ground lease of property
which includes the Premises shall ever be responsible to Tenant for the return
or application of any such deposit, whether or not it succeeds to the position
of Landlord hereunder, unless such deposit shall have been received in band by
such holder or ground lessor.

Tenant warrants and represents that all information furnished to Landlord or
Landlord's representatives in connection with this Lease are true and correct
and in respect of the financial condition of Tenant, properly reflect the same
without material adverse change, as of the date hereof. Upon Landlord's demand,
which may be made no more often than semi-annually, Tenant shall furnish to
Landlord, at Tenant's sole cost and expense, then current financial statements
of Tenant, audited (if audited statements have been recently prepared on behalf
of Tenant, or otherwise certified as being true and correct by the chief
financial officer of Tenant).

  15.17  ADDITIONAL REMEDIES OF LANDLORD.  Landlord shall have the right, but
shall not be required to do so, to pay such sums or do any act which requires
the expenditure of monies which may be necessary or appropriate by reason of the
failure or neglect of Tenant to perform any of the provisions of this Lease, and
in the event of the exercise of such right by Landlord, Tenant agrees to pay to
Landlord forthwith upon demand all such sums; and if Tenant shall default in
such payment within fifteen (15) days of such demand, Landlord shall have the
same rights and remedies as Landlord has hereunder for the failure of Tenant to
pay the Annual Base Rent.

Except as otherwise set forth herein, any obligations of Tenant as set forth
herein (including, without limitation, rental and other monetary obligations,
repair obligations and obligations to indemnify Landlord), shall survive the
expiration or earlier termination of this Lease, and Tenant shall immediately
reimburse Landlord for any expense incurred by Landlord in curing Tenant's
failure to satisfy any such obligation (notwithstanding the fact that such cure
might be effected by Landlord following the expiration or earlier termination of
this Lease).

  15.18  HOLDING OVER.  Any holding over by Tenant after the expiration of the
Lease Term shall be treated as a tenancy at sufferance at one hundred fifty
percent (150%) of the Annual Base Rent and Additional Rent herein provided to be
paid during the last twelve (12) months of the Lease Term (prorated on a

                                       48
<PAGE>

daily basis) and shall otherwise be on the terms and conditions set forth in
this Lease, as far as applicable.

  15.19  NON-SUBROGATION.  Insofar as, and to the extent that, the following
provision may be effective without invalidating or making it impossible to
secure insurance coverage obtainable from responsible insurance companies doing
business in the locality in which the Premises are located (even though extra
premium may result therefrom): Landlord and Tenant mutually agree that, with
respect to any hazard which is covered by insurance then being carried by them,
respectively, the one carrying such insurance and suffering such loss releases
the other of and from any and all claims with respect to such loss; and they
further mutually agree that their respective insurance companies shall have no
right of subrogation against the other on account thereof.  In the event that
extra premium is payable by either party as a result of this provision, the
other party shall reimburse the party paying such premium the amount of such
extra premium.  If, at the request of one party, this release and non-
subrogation provision is waived, then the obligation of reimbursement shall
cease for such period of time as such waiver shall be effective, but nothing
contained in this Section 15.19 shall derogate from or otherwise affect releases
elsewhere herein contained of either party for claims.

  15.20  RELOCATION OF PREMISES.  Tenant acknowledges that from time to time
Landlord may desire to relocate Tenant to other portions of the Building in
order to incorporate all or a portion of the Premises in portions of the
Building to be leased to tenants other than Tenant.  Tenant further acknowledges
that restrictions on the right of Landlord to effect such a relocation would
cause substantial damage to Landlord in the leasing of the Building.
Accordingly, Tenant specifically acknowledges that Landlord shall have the right
to substitute for the Premises demised under this Lease other space of
approximately the same size in the Building provided that Landlord, at
Landlord's sole cost and expense, shall place such other space in substantially
the same condition as the Premises are then in and shall pay all moving costs
including phone system, computer cabling and new letter head, if the address on
the letter head changes with the relocation.  In the event Landlord desires
Tenant to make such relocation, Landlord shall give written notice thereof to
Tenant at least forty-five (45) days prior to the date on which Tenant shall
effect such relocation.  Tenant agrees that upon notice from Landlord that the
substitute premises have been substantially completed, Tenant shall relocate to
the substitute premises furnished by Landlord and deliver occupancy of the
Premises to Landlord within thirty (30) days thereof and shall enter into a
suitable amendment of this Lease to reflect Tenant's occupancy of the substitute
premises.

                                       49
<PAGE>

  15.21  GOVERNING LAW.  This Lease shall be governed exclusively by the
provisions hereof and by the laws of the Commonwealth of Massachusetts as the
same may from time to time exist.

  15.22  DEFINITION OF ADDITIONAL RENT.  Without limiting any other provision of
this Lease, it is expressly understood and agreed that Tenant's participation in
Taxes, Operating Expenses, and all other charges which Tenant is required to pay
hereunder, together with all interest and penalties that may accrue thereon,
shall be deemed to be Additional Rent, and in the event of non-payment thereof
by Tenant, Landlord shall have all of the rights and remedies with respect
thereto as would accrue to Landlord for non-payment of Annual Base Rent.

  15.23  LANDLORD'S FEES AND EXPENSES.  Unless prohibited by applicable law,
Landlord and Tenant each agrees to pay to the amount of all reasonable legal
fees and expenses incurred by Landlord or Tenant, as the case may be, arising
out of or resulting from any act or omission by Landlord or Tenant with respect
to this Lease or the Premises, including without limitation, any breach by
Landlord or Tenant of its obligations hereunder.

Further, if Tenant shall request Landlord's consent or joinder in any instrument
pertaining to this Lease, Tenant agrees promptly to reimburse Landlord for the
reasonable legal fees incurred by Landlord in processing such request, whether
or not Landlord complies therewith; and if Tenant shall fail promptly so to
reimburse Landlord, same shall be deemed to be a default in Tenant's monetary
obligations under this Lease.

With the exception of the initial Landlord's Work, whenever Tenant shall request
approval (or this lease shall require preparation) by Landlord or the Landlord's
architect of plans, drawings, specifications, or otherwise with respect to
initial of the Premises, subsequent remodeling thereof, installation of signs
including subsequent changes thereof, or the like, Tenant specifically agrees
promptly to pay to Landlord's architect (or reimburse Landlord for the payment
Landlord makes to said architect) for all charges involved in the review (and
re-review, if necessary) and approval or disapproval thereof whether or not
approval shall ultimately be given.

  15.24  PARKING. Tenant, upon the commencement of its occupancy of the
Premises, shall have the right to use for its designated employees, as
appurtenant to the Premises, four (4) parking spaces for every 1,000 rentable
square feet in the Premises in common with other tenants of the Building located
in the parking area designated for use of tenants of the Building. Use of such
spaces may not be sold, assigned, licensed or otherwise given to any person for
any compensation or fee or otherwise. The use of such parking spaces by Tenant

                                       50
<PAGE>

in the Building may be regulated by rules and regulations issued by the Landlord
from time to time.

  15.25  AUTHORITY.  If Tenant is an entity, Tenant shall, simultaneously with
delivery of this Lease, deliver to Landlord a certified copy of a resolution of
the said entity authorizing or ratifying the execution of this Lease and such
other demonstration of existence, due authority and binding nature of Tenant's
actions in executing and delivering this Lease as Landlord or its lender(s) may
reasonably require.

  15.26 CONFIDENTIALITY. Landlord and Tenant agree that the terms and conditions
of this Lease were negotiated based on the unique positions  as to bargaining
power of the Landlord and the Tenant.  Therefore, the parties agree that certain
concessions granted to one another in this Lease were based on these unique
positions, and that communication to parties other than employees, agents,
lenders, investors, purchasers or underwriters (or as otherwise required by
applicable law or required in connection with the issuance of any securities by
Tenant) of each party may be detrimental and harmful to the Landlord's ability
to rent additional space in the building occupied by the Tenant.  Tenant hereby
agrees, therefore, not to communicate to anyone other than its agents,
employees, lenders, investors, purchasers or underwriters (or as otherwise
required by applicable law or required in connection with the issuance of any
securities by Tenant) the contents of this Lease, and any breach of the
provisions of this paragraph by the Tenant shall be considered a default by the

excluding force majeure as a justification for non-performance by Landlord,
Landlord shall not be in default hereunder and Tenant shall not be excused from
performing any of its obligations hereunder if Landlord is prevented from
performing any of its obligations hereunder due to any accident, breakage,
strike, shortage of materials, a Year 2000 problem, acts of God or other causes
beyond Landlord's reasonable control.  Tenant shall not be in default hereunder
and Landlord shall not be excused from performing any of its obligations
hereunder if Tenant is prevented from performing any of its obligations due to
any accident, breakage, strike, shortage of materials, a Year 2000 problem, acts
of God or other causes beyond Tenant's reasonable control (but specifically
excluding financial inability to perform).  This provision specifically does not
apply to either party's obligation to pay money to the other including Tenant's
obligation to pay rent under the terms of this Lease. A "Year 2000 problem"
shall mean a date-handling problem relating to the Year 2000 date change that
would cause a computer system, software or equipment to fail to correctly
perform, process and handle date-related

                      LEASE SUBORDINATION, NON-DISTURBANCE
                     OF POSSESSION AND ATTORNMENT AGREEMENT

     This Agreement ("Lease Subordination, Non-Disturbance of Possession and
Attornment Agreement" or "Agreement") is made as of the _____ day of
___________, 1998, by and among ___________________________ having a place of
business at ________________, ("Lender"), LSOF Pooled Equity L.P., a Delaware
limited partnership with an address at 600 N. Peal Street, Suite 1500, Dallas,
Texas 75201 ("Landlord"), and Freedom of Information, Inc., a Delaware
corporation with an address at 154 Crane Meadow Road, Marlborough, MA
("Tenant").

                                   WITNESSETH

     WHEREAS, Lender is relying on this Agreement as an inducement to Lender in
making and maintaining a loan ("Loan") secured by, among other things, a
Mortgage and Security Agreement dated as of _______________ ("Mortgage") given
by Borrower covering property commonly known as and numbered 154 Crane Meadow
Road, Marlborough, Massachusetts ("Property").  Lender is also the "Assignee"
under a Collateral Assignment of Leases and Rents ("Assignment") dated as of
from Borrower with respect to the Property.

     WHEREAS, Tenant is the Tenant under that certain lease ("Lease") dated
October __, 1998, made with Landlord covering certain premises ("Premises") at
the Property as more particularly described in the Lease [and in the "Notice of
Lease" dated 1998 which has been recorded at Middlesex South Registry of Deeds
in Book ______, Page _____].

     WHEREAS, Lender requires, as a condition to the making, and maintaining of
the Loan, that the Mortgage be and remain superior to the Lease and that its
rights under the Assignment be recognized.

     WHEREAS, Tenant requires, as a condition to the Lease being subordinate to
the Mortgage, that its rights under the Lease be recognized.

     WHEREAS, Lender, Landlord, and Tenant desire to confirm their understanding
with respect to the Mortgage and the Lease.

     NOW, THEREFORE, in consideration of the foregoing, the mutual covenants and
agreements contained herein, and other valuable consideration, the receipt and
adequacy of which are hereby acknowledged, and with the understanding by Tenant
that Lender shall rely hereon in making and maintaining the Loan, Lender,
Landlord, and Tenant agree as follows:
<PAGE>

     Subordination.  The Lease and the rights of Tenant thereunder are
subordinate and inferior to the Mortgage and any amendment, renewal,
substitution, extension or replacement thereof and each advance made thereunder
as though the Mortgage, and each such amendment, renewal, substitution,
extension or replacement were executed and recorded, and the advance made,
before the execution of the Lease.  Without limiting the foregoing and
notwithstanding, any other term or provision of this Agreement, Tenant's rights
with respect to proceeds of insurance and of eminent domain awards are expressly
made subject and subordinate to the rights of Lender, and the disposition of
such proceeds shall be governed by the Mortgage, and the other "Loan Documents"
referred to therein, in all respects.

     Non-Disturbance.  So long as Tenant is not in default (beyond any period
expressed in the Lease within which Tenant may cure such default) in the payment
of rent or in the performance or observance of any of the terms, covenants or
conditions of the Lease on Tenant's part to be performed or observed, (i)
Tenant's occupancy of the Premises shall not be disturbed by Lender in the
exercise of any of its rights under the Mortgage during the term of the Lease,
or any extension or renewal thereof made in accordance with the terms of the
Lease, and (ii) Lender will not join Tenant as a party defendant in any action
or proceeding for the purpose of terminating Tenant's interest and estate under
the Lease because of any default under the Mortgage.

     Attornment and Certificates.  In the event Lender succeeds to the interest
of Borrower as Landlord under the Lease, or if the Property or the Premises are
sold pursuant to the power of sale under the Mortgage, Tenant shall attorn to
Lender, or a purchaser upon any such foreclosure sale, and shall recognize
Lender, or such purchaser, thereafter as the Landlord under the Lease.  Such
attornment shall be effective and self-operative without the execution of any
further instrument.  Tenant agrees, however, to execute and deliver at any time
and from time to time, upon the request of any holder(s) of any of the
indebtedness or other obligations secured by the Mortgage, or upon request of
any such purchaser, (a) any instrument or certificate which, in the reasonable
judgment of such holder(s), or such purchaser, may be necessary or appropriate
in any such foreclosure proceeding or otherwise to evidence such attornment, and
(b) an instrument or certificate regarding the status of the Lease, consisting
of statements, if true (and if not true, specifying in what respect), (i) that
the Lease is in full force and effect, (ii) the date through which rentals have
been paid, (iii) the duration and date of the commencement of the term of the
Lease, (iv) the nature of any amendments or modifications to the Lease, (v) that
no default, or state of facts, which with the passage of time, or notice, or
both, would constitute a default, exists on the part of either party to the
Lease, and (vi) the dates on which payments of additional rent, if any, are due
under the Lease.

     Limitations.  If Lender exercises any of its rights under the Assignment or
the Mortgage, or if Lender shall succeed to the interest of Landlord under the
Lease in any manner, or if any purchaser acquires the Property, or the Premises,
upon or after

                                       2
<PAGE>

any foreclosure of the Mortgage, or any deed in lieu thereof, Lender or such
purchaser, as the case may be, shall have the same remedies by entry, action or
otherwise in the event of any default by Tenant (beyond any period expressed in
the Lease within which Tenant may cure such default) in the payment of rent or
in the performance or observance of any of the terms, covenants and conditions
of the Lease on Tenant's part to be paid, performed or observed that the
Landlord had or would have had if Lender or such purchaser had not succeeded to
the interest of the present Landlord. From and after any such attornment, Lender
or such purchaser shall be bound to Tenant under all the terms, covenants and
conditions of the Lease, and Tenant shall, from and after such attornment to
Lender, or to such purchaser, have the same remedies against Lender, or such
purchaser, for the breach of an agreement contained in the Lease that Tenant
might have had under the Lease against Landlord, if Lender or such purchaser had
not succeeded to the interest of Landlord. Provided, however, that Lender or
such purchaser shall only be bound during the period of its ownership, and that
in the case of the exercise by Lender of its rights under the Mortgage, or the
Assignment, or any combination thereof, or a foreclosure, or deed in lieu of
foreclosure, all Tenant claims shall be satisfied only out of the interest, if
any, of Lender, or such purchaser, in the Property, and Lender and such
purchaser shall not be (a) liable for any act or omission of any prior landlord
(including the Landlord); or (b) liable for or incur any obligation with respect
to the construction of the Property or any improvements of the Premises or the
Property; or (c) subject to any offsets or defenses which Tenant might have
against any prior landlord (including the Landlord); or (d) bound by any rent or
additional rent which Tenant might have paid for more than the then current
rental period to any prior landlord (including the Landlord); or (e) bound by
any amendment or modification of the Lease, or any consent to any assignment or
sublet, made without Lender's prior written consent; or (f) bound by or
responsible for any security deposit not actually received by Lender; or (g)
liable for or incur any obligation with respect to any breach of warranties or
representations of any nature under the Lease or otherwise including without
limitation any warranties or representations respecting use, compliance with
zoning, landlord's title, landlord's authority, habitability and/or fitness for
any purpose, or possession; or (h) liable for consequential damages.

     Rights Reserved.  Nothing herein contained is intended, nor shall it be
construed, to abridge or adversely affect any right or remedy of:  (a) the
Landlord under the Lease, or any subsequent Landlord, against the Tenant in the
event of any default by Tenant (beyond any period expressed in the Lease within
which Tenant may cure such default) in the payment of rent or in the performance
or observance of any of the terms, covenants or conditions of the Lease on
Tenant's part to be performed or observed; or (b) the Tenant under the Lease
against the original or any prior Landlord in the event of any default by the
original Landlord to pursue claims against such original or prior Landlord
whether or not such claim is barred against Lender or a subsequent purchaser.

                                       3
<PAGE>

     Notice and Right to Cure.  Tenant agrees to provide Lender with a copy of
each notice of default given to Landlord under the Lease, at the same time as
such notice of default is given to the Landlord, and that in the event of any
default by the Landlord under the Lease, Tenant will take no action to terminate
the Lease (a) if the default is not curable by Lender (so long as the default
does not interfere with Tenant's use and occupation of the Premises), or (b) if
the default is curable by Lender, unless the default remains uncured for a
period of thirty (30) days after written notice thereof shall been given,
postage prepaid, to Landlord at Landlord's address, and to Lender at the address
provided in Section 7 below; provided, however, that if any such default is such
that it reasonably cannot be cured within such thirty (30) day period, such
period shall be extended for such additional period of time as shall be
reasonably necessary (including, without limitation, a reasonable period of time
to obtain possession of the Property and to foreclose the Mortgage), if Lender
gives Tenant written notice within such thirty (30) day period of Lender's
election to undertake the cure of the default and if curative action (including,
without limitation, action to obtain possession and foreclose) is instituted
within a reasonable period of time and is thereafter diligently pursued.  Lender
shall have no obligation to cure any default under the Lease.

     Notices.  Any notice or communication required or permitted hereunder shall
be in writing, and shall be given or delivered: (i) by United States mail,
registered or certified, postage fully prepaid, return receipt requested, or
(ii) by recognized courier service or recognized overnight delivery service; and
in any event addressed to the party for which it is intended at its address set
forth below:

     To Lender:

     To Tenant:     Freedom of Information, Inc.
                    154 Crane Meadow Road,
                    Marlborough, MA

or such other address as such party may have previously specified by notice
given or delivered in accordance with the foregoing.  Any such notice shall be
deemed to have been given and received on the date delivered or tendered for
delivery during normal business hours as herein provided.

     No Oral Change.  This Agreement may not be modified orally or in any manner
than by an agreement in writing signed by the parties hereto or their respective
successors in interest.

     Successors and Assign.  This Agreement shall inure to the benefit of and be
binding upon the parties hereto, their respective heirs, personal
representatives, successors and assigns, and any purchaser or purchasers at
foreclosure of the Property or any portion thereof, and their respective heirs,
personal representatives, successors and assigns.

                                       4
<PAGE>

     Payment of Rent To Lender.  Tenant acknowledges that it has notice that the
Lease and the rent and all sums due thereunder have been assigned to Lender as
part of the security for the Obligations secured by the Mortgage.  In the event
Lender notifies Tenant of a default under the Loan and demands that Tenant pay
its rent and all other sums due under the Lease to Lender, Tenant agrees that it
will honor such demand and pay its rent and all other sums due under the Lease
to Lender, or Lender's designated agent, until otherwise notified in writing by
Lender.  Borrower unconditionally authorizes and directs Tenant to make rental
payments directly to Lender following receipt of such notice and further agrees
that Tenant may rely upon such notice without any obligation to further inquire
as to whether or not any default exists under the Mortgage or the Assignment,
and that Borrower shall have no right or claim against Tenant for or by reason
of any payments of rent or other charges made by Tenant to Lender following
receipt of such notice.

     No Amendment or Cancellation of Lease.  So long as the Mortgage remains
undischarged of record, Tenant shall not amend, modify, cancel or terminate the
Lease, or consent to an amendment, modification, cancellation or termination of
the Lease, or agree to subordinate the Lease to any other mortgage, without
Lender's prior written consent in each instance.

     Options.  With respect to any options for additional space provided to
Tenant under the Lease, Lender agrees to recognize the same if Tenant is
entitled thereto under the Lease after the date on which Lender succeeds as
Landlord under the Lease by virtue of foreclosure or deed in lieu of foreclosure
or Lender takes possession of the Premises; provided, however, Lender shall not
be responsible for any acts of any prior landlord under the lease, or the act of
any tenant, subtenant or other party which prevents Lender from complying with
the provisions hereof and Tenant shall have no right to cancel the Lease or to
make any claims against Lender on account thereof.

     Captions.  Captions and headings of sections are not parts of this
Agreement and shall not be deemed to affect the meaning or construction of any
of the provisions of this Agreement.

     Counterpart.  This Agreement may be executed in several counterparts each
of which when executed and delivered is an original, but all of which together
shall constitute one instrument.

     Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts.

     Parties Bound.  The provisions of this Agreement shall be binding upon and
inure to the benefit of Tenant, Lender and Borrower and their respective
successors and assigns; provided, however, reference to successors and assigns
of Tenant shall not constitute a consent by Landlord or Borrower to an
assignment or sublet by

                                       5

Tenant, but has reference only to those instances in which such consent is not
required pursuant to the Lease or for which such consent has been given.
