on such access, such as card access systems, and to Section 13.4.2 below. Access

termination or expiration of this Lease in the same condition as they were
provided to Tenant, damage by reasonable wear and tear, but not casualty,

Date (as defined below) and expiring at midnight of the last day of the Term,
unless sooner terminated as provided herein.

     2.3.2. The Scheduled Commencement Date set forth in Section 1.2 is an
estimated Commencement Date. The actual Commencement Date shall be the date

provisions of this Lease; provided, however, that the term of this Lease shall
be computed from the first day of the calendar month following the Commencement
Date if the Commencement Date is not on the first day of the month.
Notwithstanding the Scheduled Commencement Date specified in Section 1.2, if for
any reason Landlord cannot deliver possession of the Premises to Tenant on said
date, Landlord shall not be subject to any liability therefor, nor shall such
failure affect the validity of this Lease or the obligations of Tenant
hereunder; provided, however, in such a case, Tenant shall not be obligated to
pay rent or perform any other obligation of Tenant under this Lease, except as

<PAGE>

Option Period (the "Extension Term"), provided that: (i) this Lease is in full

or sublet any portion of the Premises; and (iv) Tenant has given Landlord
written notice of its election to extend the Term no later than 9 months prior
to the expiration date of the original Term of this Lease. In the event that
Tenant shall extend the Term as aforesaid, such extension shall be upon the same
terms and conditions as set forth herein except that: no further right to extend
shall be deemed to be included; and the annual Fixed Rent payable hereunder
shall be adjusted in accordance with the provisions of Section 3. Should Tenant
so extend the Term of this Lease, the term "Term" as used herein shall mean the
original Term together with the Extension Term.

3.   RENT

3.1. FIXED RENT.

     3.1.1. Tenant agrees to pay to Landlord, without offset or deduction and
without previous demand therefor, except as expressly provided herein, annual
Fixed Rent during each Lease Year (as defined below) of the Term. The annual
Fixed Rent during the original Term shall be as provided in Section 1.2 above.

     3.1.2. All such annual Fixed Rent shall be payable in equal monthly

rata basis, and if the Commencement Date, except as otherwise expressly provided
in Section 1.2 above, occurs 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 Fixed Rent for the partial month from such
date to the first day of the succeeding calendar month, and the monthly Fixed
Rent for such succeeding calendar month.

     3.1.4. For the purposes of this Lease, "Lease Year" shall mean each
successive 12-month period included in whole or in part in the Term of this
Lease; the first Lease Year beginning on the Commencement Date and ending at

(provided that if the Commencement Date is not the first day of a calendar
month, the first Lease Year shall end at midnight on the last day of the
calendar month which includes the first anniversary of the Commencement Date).
If the first Lease Year of the Term shall be greater than one full calendar
year, the annual Fixed Rent for such Lease Year shall be increased
proportionately to the greater length of such Lease Year.

     3.1.5. Notwithstanding the fact that the amounts of Fixed Rent set forth in
this Lease were or may have been determined with reference to the floor area of
the Premises, said amounts as set forth above are stipulated to be the amounts
of Fixed Rent due hereunder. whether or not the actual floor area of the
Premises are in fact more or less than the floor area figures used to determine
said Fixed Rent.

option to extend the Term hereof in accordance with Section 2.4), the annual

<PAGE>

Lease Year of the Extension Term shall be determined as of the first day of the
inclusion of the Available Space into the Premises and Extension Term,
respectively, and shall equal the Fair Market Rental Value.

     3.2.2. The "Fair Market Rental Value" shall mean the market rate for the
rental of the Premises for the Extension Term including all relevant factors,
but in no event less than the Fixed Rent payable during the last Lease Year of
the original Term. The Fair Market Rental Value shall be determined as follows:

     (a)  After the exercise by Tenant of its option to extend the Term,
          Landlord shall advise Tenant in writing of Landlord's determination of
          the Fair Market Rental Value within twenty (20) business days of
          Landlord's receipt of Tenant's exercise notice (but in no event shall
          Landlord be required to provide such determination prior to nine (9)
          months prior to the expiration of the original Term). Tenant shall be
          deemed to have accepted the rental amount contained in Landlord's said
          notice, and such rental rate shall be conclusively deemed to be the
          Fair Market Rental Value, unless Tenant notifies Landlord in writing,
          within 10 business days after Landlord's notice (but in no event shall
          Tenant's notice be sent less than eight (8) months prior to the
          expiration of the original Term), that Tenant disputes the
          aforementioned determination by Landlord and Tenant affirmatively
          elects to either (i) rescind its exercise of the extension option, in
          which event Tenant's extension option shall be of no further force or
          effect, or (ii) that Tenant disputes the aforementioned determination
          by Landlord, in which event the parties shall proceed to the Fair
          Market Rental Value determination as set forth in Subsection (c)
          below.

     (b)  In the event that Tenant so disputes the determination of the Fair
          Market Rental Value by Landlord, and the Landlord and Tenant are
          unable to agree on the Fair Market Rental Value within 30 days, the
          same shall be determined as follows: Landlord and Tenant each shall,
          within thirty (30) days thereafter, appoint an independent appraiser
          who shall be instructed to determine independently the Fair Market
          Rental Value. If the difference between the amounts so determined by
          such appraisers does not exceed ten percent (10%) of the lesser of
          such amounts, then the Fair Market Rental Value shall be an amount
          equal to fifty percent (50%) of the total of the amounts so
          determined. If the difference between the amounts so determined shall
          exceed ten percent (10%) of the lesser of such amounts, then such two
          (2) appraisers shall have ten (10) days thereafter to appoint a third
          appraiser, but if such appraisers fail to do so within such ten (10)
          day period, then either Landlord or Tenant may request the Greater
          Boston Real Estate Board or any successor organization thereto to
          appoint an appraiser within ten (10) days of such request, and both
          Landlord and Tenant shall be bound by any appointment so made within
          such ten (10) day period. If no such appraiser shall have been
          appointed within such ten (10) days either Landlord or Tenant may
          apply to any court having jurisdiction to have such appointment made
          by such court. Any appraiser appointed by the original appraisers, by
          the Greater Boston Real Estate Board or by such court shall be
          instructed to determine the Fair Market Rental Value in accordance
          with the definition of such term contained herein and within twenty
          (20) days after its appointment. If the third appraisal shall exceed
          the higher of the first two appraisals, the Fair Market Rental Value
          shall be the higher of the first two appraisals; if the third
          appraisal is less than the lower of the first two appraisals, the Fair
          Market Rental Value shall be the lower of the first two appraisals.
          In all other cases, the Fair Market Rental Value shall be equal to
          the third appraisal. Notwithstanding the foregoing, if either party
          shall fail to appoint its appraiser within the 30 day period specified
          above (such party being referred to herein as the "failing party"),
          the other party may serve notice on the failing party requiring the
          failing

                                        5

<PAGE>

          party to appoint its appraiser within ten (10) days of the giving of
          such notice. If the failing party shall not respond by appointment of
          its appraiser within said ten day period, then the appraiser appointed
          by the other party shall be the sole appraiser whose determination of
          the Fair Market Rental Value shall be binding and conclusive upon
          Tenant and Landlord. Each party shall pay for the fees and expenses of
          the appraiser appointed by it, but the fees and expenses of the third
          appraiser shall be shared equally by the parties. All appraisers
          appointed hereunder shall be MAI appraisers, so-called, knowledgeable
          in the field of commercial real estate and experienced in the Boston
          Metro-West market. The foregoing determination shall be conclusive,
          final and binding on the parties and enforceable in any court having
          jurisdiction over the parties.

     (c)  If the parties are unable to agree on the Fair Market Rental Value (or
          the arbitration procedure set forth above has not concluded) prior to
          the first day of the Extension Term, Tenant shall make monthly
          payments on account of Fixed Rent (in addition to all additional rent
          and other payments hereunder) in the amount of Landlord's initial
          designation of the Fair Market Rental Value, until the Fair Market
          Rental Value has been finally established as herein provided, at which
          time an appropriate retroactive Fixed Rent adjustment payment or
          refund shall be made, if necessary.

     3.2.3. During the Extension Term, Tenant shall continue to pay all
additional rent and other payments as provided in this Lease.

3.3. LATE PAYMENT.

If any Fixed Rent, additional rent or any other payments due hereunder from
Tenant are not paid within 10 days of the due date thereof, Tenant shall be
charged a late fee of $250.00 for each late payment for each month or portion
thereof that said payment remains outstanding. Said late fee shall be payable in
addition to and not in exclusion of any other remedies of Landlord on account of
such late payments, including without limitation the obligation to pay interest
on late payments, as provided in Section 12.3.

4.   USE OF PREMISES; ALTERATIONS

4.1. PERMITTED USE.

     4.1.1. Tenant agrees that the Premises shall be used and occupied by Tenant
only for the Permitted Use, as provided in Section 1.2 of this Lease, and for no
other purpose or purposes.

     4.1.2. Tenant further covenants and 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 as provided in the next paragraph.

                                        6

<PAGE>

          Notwithstanding the foregoing, Tenant may, at Tenant's sole expense,
          locate a sign at the entrance door to 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 and
          location shall be subject to the prior approval of Landlord, which
          approval shall not be unreasonably withheld, conditioned or delayed.
          Where Landlord establishes reasonable standards for such signs, Tenant
          agrees to conform to the same and to submit for Landlord's prior
          approval, such approval not unreasonably to be withheld, conditioned
          or delayed, a plan or sketch of the sign to be placed on or about such
          entry door and location thereof. Without limitation, lettering on
          windows and window displays are expressly prohibited. Landlord shall
          also provide Tenant, and any permitted successor or assign, with a
          listing on the Building's main tenant directory.

     (c)  Tenant shall not perform any act or any practice which may injure the
          Premises, or any other part of the Building or the Property, 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, and Tenant shall permit no waste with respect to the
          Premises or the Property.

     (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 established by Landlord by
          suitable notice, including without limitation the current rules and
          regulations, a copy of which are attached hereto as Exhibit B.
          Landlord shall not, however, be responsible for the noncompliance of
          any such rules and regulations by any other tenant or occupant.

     (f)  Tenant shall, at Tenant's sole expense, promptly comply with all
          applicable laws, ordinances, rules, regulations, orders, certificates
          of occupancy, conditional use or other permits, variances, covenants
          and restrictions of record, the reasonable recommendations of
          Landlord's engineers or other consultants, and requirements of any
          fire insurance underwriters, rating bureaus or government agencies,
          now in effect or which may hereafter come into effect during the Lease
          Term relating in any manner to the Premises or the particular
          occupation or particular use (as opposed to office use generally, the
          cost for which shall be part of Operating Expenses to the extent set
          forth in Section 8.2) by Tenant (or any of its employees, visitors or
          invitees) of the Premises ("Laws and Restrictions").

4.2. ALTERATIONS.

Tenant shall not make any alterations, improvements, additions, utility
installations or repairs (hereinafter collectively referred to as "Alterations")
to the Premises, except in accordance with this Section 4.2 and with the prior
written consent of Landlord, which Landlord agrees not unreasonably to withhold,
condition or delay as to nonstructural Alterations (nonstructural Alterations
being those that do not materially, adversely affect the Building's structure,
roof, exterior or mechanical, electrical, plumbing, life safety or other
Building systems or architectural design, character or use of the Building or
Premises). Without limiting any of the terms hereof Landlord will not approve
any Alterations requiring unusual expense to readapt the Premises to normal
office use on lease termination or increasing the cost of construction,
insurance or taxes on the Building or of Landlord's services to the Premises,
unless Tenant first gives

                                        7

<PAGE>

assurances or security acceptable to Landlord that such re-adaptation will be
made prior to such termination without expense to Landlord and makes provisions
acceptable to Landlord for payment of such increased cost. All Alterations made
by Tenant shall be made in accordance with plans and specifications which have
been approved in writing by the Landlord, in Landlord's reasonable discretion,
pursuant to a duly issued permit, and in accordance with all Laws and
Restrictions, the provisions of this Lease and in a good and first-class
workmanlike manner using new materials of same or better quality as base
building standard materials, free of all liens and encumbrances. All Alterations
shall be performed by a contractor or contractors selected by Tenant and
approved in writing by Landlord, in Landlord's reasonable discretion. Except for
any non-structural Alteration costing less than $10,000.00 (per such
Alteration), Tenant shall pay to Landlord a fee equal to the lesser of (i) five
percent (5%) of the cost of any such Alterations, or (ii) Landlord's actual
costs incurred, to compensate Landlord for the overhead and other costs it
incurs in reviewing the plans therefor and in monitoring the construction of the
Alterations; in the event any non-structural Alteration costing less than
$10,000.00 requires Landlord's specific review or monitoring, Tenant shall pay
the reasonable third party cost therefor incurred by Landlord. If, as a result
of any Alterations made by Tenant, Landlord is obligated to comply with the
Americans With Disabilities Act or any other Laws or Restrictions and such
compliance requires Landlord to make any improvement or Alteration to any
portion of the Building, as a condition to Landlord's consent, Landlord shall
have the right to require Tenant to pay to Landlord prior to the construction of
any Alteration by Tenant, the entire cost of any improvement or alteration
Landlord is obligated to complete by such law or regulation. Tenant agrees to
obtain or cause its contractor(s) to obtain, prior to the commencement of any
work or Alterations, "builder's all risk" insurance in an amount and with such
commercially reasonable coverages approved by Landlord and worker's compensation
insurance in the statutorily required amount(s) and evidence of all such
insurance shall be furnished to Landlord prior to the performance by such
contractor(s) or person(s) of any work in respect of the Premises. Landlord
shall have the right to stop any work not being performed in conformance with
this Lease, and, at its option, but only after notice to Tenant and Tenant fails
to promptly remedy such non-conformance, may repair or remove non-conforming
work at the expense of Tenant. Tenant hereby indemnifies and holds Landlord
harmless from and against any liens, encumbrances and violations of Laws and
Restrictions. The filing of any lien or encumbrance, or the violation of Laws or
Restrictions, shall constitute a default hereunder. The repair and indemnity
obligations of Tenant hereunder, including Tenant's obligations to repay
Landlord the cost of repairing or removing Alterations, shall survive the
termination of this Lease. All Alterations performed by Tenant in the Premises
shall remain therein (unless, at the time of Landlord's consent therefore,
Landlord directs Tenant to remove the same on termination or expiration of this
Lease) and, at termination or expiration, shall be surrendered as a part
thereof, except for Tenant's usual trade fixtures, furniture and equipment
installed prior to or during the Lease term at Tenant's cost, which trade
fixtures, furniture and equipment Tenant shall remove in their entirety prior to
the termination or expiration of this Lease. Tenant agrees to repair any and all
damage to the Premises resulting from such removal (including removal of
Tenant's Alterations directed by Landlord) or, if Tenant fails to do so and
Landlord so elects, to pay Landlord for the cost of any such repairs forthwith
after billing therefor.

5.   ASSIGNMENT AND SUBLETTING

5.1. GENERALLY.

     5.1.1. Notwithstanding any other provisions of this Lease, Tenant
covenants and agrees that it will not assign this Lease or sublet (which term,
without limitation, shall include the granting of any concessions, licenses,
occupancy rights, 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,
conditioned or delayed. A change in Tenant's name shall not constitute an
assignment or sublease hereunder, provided Tenant notifies Landlord in writing
of

                                        8

<PAGE>

such name change prior to making such change. Tenant shall not collaterally
assign this Lease (or any portion thereof) or permit any assignment of this
Lease by mortgage, other encumbrance or operation of law.

     5.1.2. Without limitation, it shall not be unreasonable for Landlord to
withhold such approval from any assignment or subletting where, in Landlord's
opinion: (i) the proposed assignee or sublessee does not have a financial
standing and credit rating equal to Tenant at the time of this Lease (or at the
time of the proposed assignment or subletting, if greater); (ii) the proposed
assignee or sublessee, in Landlord's reasonable discretion, does not have a good
reputation in the community; (iii) the business in which the proposed assignee
or sublessee is engaged could, in Landlord's reasonable discretion, detract from
the Building, its value or the costs of ownership thereof; (iv) Intentionally
Deleted; (v) the proposed sublessee or assignee is a current tenant or a
prospective tenant (meaning such tenant has been shown space in the last six (6)
months or has been presented with or has made an offer to lease space) of the
Building or of the Office Park; (vi) the use of the Premises by any sublessee or
assignee (even though a Permitted Use) violates any use restriction granted by
Landlord in any other lease or would otherwise cause Landlord to be in violation
of its obligations under another lease or agreement to which Landlord is a
party; (vii) if such assignment or subleasing is not approved of by the holder
of any mortgage on the Property (if such approval is required); (viii) a
proposed assignee's or subtenant's business will impose a burden on the
Property's parking facilities, elevators, common areas, facilities, or utilities
that is greater than the burden permitted under this Lease, in Landlord's
reasonable judgment; (ix) any guarantor of this Lease refuses to consent to the
proposed transfer or to execute a written agreement reaffirming the guaranty;
(x) Tenant is in default (beyond applicable notice or cure periods) of any of
its obligations under the Lease at the time of the request or at the time of the
proposed assignment or sublease; (xi) if requested by Landlord, the assignee or
subtenant refuses to sign a commercially reasonable non-disturbance and
attornment agreement in favor of Landlord's lender; (xii) Landlord has sued or
been sued by the proposed assignee or subtenant or has otherwise been involved
in a legal dispute with the proposed assignee or subtenant; (xiii) the assignee
or subtenant is involved in a business which is not in keeping with the then
current standards of the Property; (xiv) the assignment or sublease will result
in there being more than two (2) subtenants of the Premises (e.g., the assignee
or subtenant intends to use the Premises as an executive suite); or (xv) the
assignee or subtenant is a governmental or quasi-governmental entity or an
agency, department or instrumentality of a governmental or quasi-governmental
agency. 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.

     5.1.3. Any request by Tenant for such consent shall set forth or be
accompanied by, in detail reasonably satisfactory to Landlord, the
identification of the proposed assignee or sublessee, its financial condition
and the terms on which the proposed assignment or subletting is to be made,
including, without limitation, a final copy of all assignment and sublease
documents (with copies of such fully executed copies to follow promptly and
Landlord's consent, if granted, shall be expressly conditioned upon receipt
thereof), and clearly stating the rent or any other consideration to be paid in
respect thereto; and such request shall be treated as Tenant's warranty in
respect of the information submitted therewith. Tenant's request shall not be
deemed complete or submitted until all of the foregoing information has been

                                        9

<PAGE>

received by Landlord. Landlord shall respond to such request for consent within
15 business days following Landlord's receipt of all information, documentation
and security required by Landlord with respect to such proposed sublease or
assignment.

     5.1.4. The foregoing restrictions shall be binding on any assignee or
sublessee to which Landlord has consented, provided, notwithstanding anything
else contained in this Lease, Landlord's consent to any further assignment,
subleasing or any sub-subleasing by any approved assignee or sublessee may be
withheld by Landlord at Landlord's sole and absolute discretion.

     5.1.5. Consent by Landlord to any assignment or subleasing shall not
include consent to the assignment or transferring of any lease renewal,
extension or other option, first offer, first refusal or other rights granted
hereunder, or any special privileges or extra services granted to tenant by
separate agreement (written or oral), or by addendum or amendment of the Lease.

     5.1.6. In the case of any assignment of this Lease or subletting of the
Premises, the Tenant named herein shall be and remain fully and primarily liable
for the obligations of Tenant hereunder, notwithstanding such assignment or
subletting, including, without limitation, the obligation to pay the Fixed Rent
and other amounts provided under this Lease, and the Tenant shall be deemed to
have waived all suretyship defenses.

     5.1.7. In addition to the foregoing, 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 satisfactory to Landlord, to be bound by:
(i) with respect to an assignment, all the obligations of Tenant hereunder,
including, without limitation, the obligation to pay Fixed Rent and other
amounts provided for under this Lease, and (ii) with respect to a sublease,
those obligations under the Lease applicable to the subleased premises and/or
incorporated in the sublease; and (iii) with respect to both an assignment and
sublease, the covenant regarding use and the covenant against further assignment
and subletting.

5.2. REIMBURSEMENT, RECAPTURE AND EXCESS RENT.

     5.2.1. Tenant shall, upon demand, reimburse Landlord for the reasonable
fees and expenses (including legal and administrative fees and costs) 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 subject to the applicable
grace and cure period set forth in Section 12.1(b).

     5.2.2. If Tenant requests Landlord's consent to assign this Lease or sublet
all or a portion of the Premises, Landlord shall have the option, exercisable by
written notice to Tenant given within 15 days after Landlord's receipt of
Tenant's completed request, to terminate this Lease as of the date of the
proposed sublease or assignment. 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 Term and thereafter, to the extent
necessary in Landlord's judgment, Landlord, at its own cost and expense, may
have access to and may make modification to the Premises (or portion thereof) so
as to make such portion a self-contained rental unit with access to common
areas, elevators and the like. Fixed Rent and the Rentable Floor Area of the
Premises shall be adjusted according to the extent of the Premises for which the
Lease is terminated.

     5.2.3. 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

                                       10

<PAGE>

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, in the case of
an assignment, fifty percent (50%) of all the consideration (or the cash
equivalent thereof) therefor and in the case of a subletting, fifty percent
(50%) of all any such excess rent. For the purposes of this subsection, the term
"rent" or "consideration" shall mean all Fixed 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 including, without limitation, key
money, or bonus money paid by the assignee or subtenant to Tenant in connection
with such transaction and any payment in excess of fair market value for
services rendered by Tenant to the assignee or subtenant or for assets,
fixtures, inventory, equipment or furniture transferred by Tenant to the
assignee or subtenant in connection with any such transaction, but shall exclude
any separate payments by Tenant for reasonable attorney's fees, the reasonable
cost of any reasonable Alterations made by Tenant to the Premises (amortized
over the Lease Term), and broker's commissions in connection with such
assignment or subletting.

     5.2.4. If the Premises or any part thereof are sublet by Tenant, following
the occurrence of a default which has continued beyond the applicable cure
period, Landlord, in addition to any other remedies provided hereunder or at
law, may at its option collect directly from such sublessee(s) all rents
becoming due to the Tenant under such sublease(s) and apply such rent against
any amounts due Landlord by Tenant under this Lease, and Tenant hereby
irrevocably authorizes and directs such sublessee(s) to so make all such rent
payments, if so directed by Landlord; and it is understood that no such election
or collection or payment shall be construed to constitute a novation of this
Lease or a release of Tenant hereunder, or to create any lease or occupancy
agreement between the Landlord and such subtenant or impose any obligations on
Landlord, or otherwise constitute the recognition of such sublease by Landlord
for any purpose whatsoever.

     5.2.5. The following terms and conditions shall apply to any subletting by
Tenant of all or any part of the Premises and shall be deemed included in all
subleases under this Lease whether or not expressly incorporated therein:

     Tenant hereby absolutely and unconditionally assigns and transfers to
Landlord all of Tenant's interest in all rentals and income arising from any
sublease entered into by Tenant, and Landlord may collect such rent and income
and apply same toward Tenant's obligations under this Lease; provided, however,
that until a default beyond applicable notice and cure periods occurs in the
performance of Tenant's obligations under this Lease, Tenant may receive,
collect and enjoy the rents accruing under such sublease. Landlord shall not, by
reason of this or any other assignment of such rents to Landlord nor by reason
of the collection of the rents from a subtenant, be deemed to have assumed or
recognized any sublease or to be liable to the subtenant for any failure of
Tenant to perform and comply with any of Tenant's obligations to such subtenant
under such sublease, including, but not limited to, Tenant's obligation to
return any security deposit. Tenant hereby irrevocably authorizes and directs
any such subtenant, upon receipt of a written notice from Landlord stating that
a default beyond applicable notice and cure periods exists in the performance of
Tenant's obligations under this Lease, to pay to Landlord the rents due as they
become due under the sublease. Tenant agrees that such subtenant shall have the
right to rely upon any such statement and request from Landlord, and that such
subtenant shall pay such rents to Landlord without any obligation or right to
inquire as to whether such default exists and notwithstanding any notice from or
claim from Tenant to the contrary. In the event Landlord terminates this Lease
by reason of a default of Tenant, Landlord at its option and without any
obligation to do so, may require any subtenant to attorn to Landlord, in which
event Landlord shall undertake the obligations of Tenant under such sublease
from the time of the exercise of said option to the termination of such
sublease; provided, however, Landlord shall not be liable for any prepaid rents
or security deposit paid by

                                       11

such subtenant to Tenant, unless Landlord actually receives such security
deposit, or for any other prior defaults of Tenant under such sublease.

5.3. CERTAIN TRANSFERS.

     5.3.1. If at any time Tenant's interest in this Lease is held by a
corporation, trust, partnership, limited liability company or other entity, the
transfer of a controlling interest in the voting stock, beneficial interests,
partnership interests, membership interests or other ownership interests therein
(whether at one time or in the aggregate) shall be deemed an assignment of this
Lease, and shall require Landlord's prior written consent. The foregoing
provisions shall not be applicable so long as the Tenant is a corporation, the
outstanding voting stock of which is listed on a recognized security exchange,
or if at least 80% of its voting stock is owned by another corporation, the
voting stock of which is so listed. For the purposes hereof, a "controlling
interest" shall mean any transfer that results in the change (whether at one
time or in the aggregate) in the effective control over the management of such
entity.

     5.3.2. To enable Landlord to determine the ownership of Tenant, Tenant
agrees to furnish to Landlord, from time to time promptly after Landlord's
reasonable request therefor, (i) if the second to last sentence of subsection
5.3.1 if applicable, proof of listing on a recognized security exchange, or (ii)
if the last sentence of subsection 5.3.1 is not applicable, an accurate and
complete listing of the holders of its stock, beneficial interests, partnership
interests, membership interests or other ownership interests therein as of such
request and as of the date of this Lease. Landlord shall use reasonable efforts
to keep confidential any information received by Landlord pursuant to this
Section 5.3, provided, however, that Landlord shall have the right to disclose
any such information to existing or prospective mortgagees, or prospective
purchasers of the Building.

     5.3.3. Notwithstanding any other provision of this Section, (a)
transactions with an entity (i) into or with which Tenant is merged or
consolidated, (ii) to which all or substantially all of Tenant's assets are
transferred as a going concern, (iii) which controls or is controlled by Tenant
or is under common control with Tenant, or (b) any transfer of stock, equity or
other indicia of ownership of or interest in Tenant resulting from (i) an
initial or subsequent offering, sale transfer or conveyance of such stock,
equity or ownership interest on any recognized securities market, or (ii) the
transfer, exchange, acquisition or conveyance of any stock, equity or other
ownership interest by, to, from any entity providing financing or capitalization
to Tenant, shall not be deemed to be an assignment or subletting within the
meaning of this Section, provided that in any of such events (1) Landlord
receives prior written notice of any such transactions, (2) except in any
instance where Tenant is the surviving entity following any such transaction
described in (a) above, the assignee or subtenant agrees directly with Landlord,
by written instrument in form reasonably satisfactory to Landlord, to be bound
by all the obligations of Tenant hereunder including, without limitation, the
covenant against further assignment and subletting, (3) in no event shall Tenant
be released from its obligations under this Lease, (4) any such transfer or
transaction is for a legitimate, regular business purpose of Tenant other than a
transfer of Tenant's interest in this Lease, and (5) the involvement by Tenant
or its assets in any transaction, or series of transactions (by way of merger,
sale, acquisition, financing, refinancing, transfer, leveraged buy-out or
otherwise) whether or not a formal assignment or hypothecation of this Lease or
Tenant's assets occurs, will not result in a reduction of the "Net Worth" of
Tenant as hereinafter defined as it exists immediately prior to said transaction
or transactions constituting such reduction. "Net Worth" of Tenant for purposes
of this section shall be the net worth of Tenant (excluding any guarantors)
established under generally accepted accounting principles consistently applied.

6.   CONDITION OF PREMISES AND RESPONSIBILITY FOR REPAIRS

6.1. CONDITION OF PREMISES.

     6.1.1. Subject to Landlord substantially completing Landlord's Work (as
defined below) as set forth herein, Tenant accepts the Premises and the Building
in their present "as is" condition, without representation or warranty, express
or implied, in fact or in law, by Landlord and without recourse to Landlord as
to the nature, condition or usability thereof; and Tenant agrees that except as
expressly set forth in this Section 6.1., Landlord has no work to perform in or
on the Premises to prepare the Premises for Tenant's use and occupancy, and that
any and all work to be done in or on the Premises will be performed by Tenant at
Tenant's sole cost and expense in accordance with the terms of this Lease. It
being understood that Landlord shall deliver the Premises with all electrical,
mechanical, plumbing, HVAC and other systems serving the Premises in good
working order, subject to punchlist items and minor repairs relating thereto
that do not materially interfere with Tenant's use of the Premises and subject
to the terms and conditions of this Lease. Prior to the Commencement Date,
Landlord shall substantially complete the work shown on Exhibit D attached
hereto ("Landlord's Work"). Provided that Tenant does not interfere with or
delay the completion by Landlord or its agents or contractors of Landlord's
Work, Tenant shall have the right to enter the Premises up to fourteen (14) days
prior to the anticipated Commencement Date for the purpose of installing
furniture, trade fixtures, equipment, and similar items. Tenant shall be liable
for any damages or delays caused by Tenant's activities at the Premises.
Provided that Tenant has not begun operating its business from the Premises, and
subject to all of the terms and conditions of the Lease, the foregoing activity
shall not constitute the delivery of possession of the Premises to Tenant and
the Lease term shall not commence as a result of said activities. Prior to
entering the Premises Tenant shall obtain all insurance it is required to obtain
by the Lease and shall provide certificates of said insurance to Landlord.
Tenant shall coordinate such entry with Landlord's building manager, and such
entry shall be made in compliance with all terms and conditions of this Lease
and the Rules and Regulations attached hereto.

6.2. INTENTIONALLY OMITTED.

6.3. REPAIRS TO BE MADE BY LANDLORD.

     6.3.1. Except as otherwise provided in this Lease, Landlord agrees to keep
in good order, condition and repair, the roof, exterior walls, structural
components and common building systems of the Building insofar as they affect or
serve the Premises and the appurtenant common areas of the Building, and to
maintain, repair and replace, in a good working order and condition, the HVAC
(except the supplemental HVAC system and equipment serving Tenant's computer
room as set forth below), plumbing electrical and other mechanical systems and
equipment serving the Premises, unless installed by or for Tenant or exclusively
serving and located within the Premises. Without limitation, Landlord shall in
no event be responsible to Tenant for the condition of glass in and about the
Premises or for the doors leading directly to the Premises, or for any
Alterations installed by or at Tenant's request, or for any condition in the
Premises or, subject to Section 13.22, 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 also agrees to maintain the parking areas,
roadways and landscaping on the Property surrounding the Building in good order
and repair, including but not limited to providing adequate lighting and snow
removal therefrom. Landlord shall not be responsible to make any improvements or
repairs to the Building or the Premises other than as expressed in this Section
unless expressly otherwise provided in this Lease. All costs incurred by
Landlord in connection with the foregoing obligations shall be included as part
of Operating Expenses, subject to the terms of Section 8.2.

                                       13

<PAGE>

     6.3.2. Landlord shall never be liable for any failure to make repairs
which, under the provisions of this Section or elsewhere in this Lease, Landlord
has undertaken to make unless: (a) Tenant, to the extent it has knowledge of any
such defective condition, 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 (b) Landlord has failed to
commence to make such repairs within a reasonable time after receipt of such
notice if any repairs are, in fact, necessary.

6.4. MAINTENANCE AND REPAIRS TO BE MADE BY TENANT.

     6.4.1. Tenant covenants and agrees that Tenant will keep neat and clean and
maintain in good order, condition and repair, the Premises and every part
thereof (and any signs permitted hereunder), and specifically including, without
limitation, the supplemental HVAC system and equipment serving Tenant's computer
room, throughout the Lease Term, excepting only those repairs for which Landlord
is responsible under the terms of this Lease, damage by fire or other casualty
or as a consequence of the exercise of the power of eminent domain and
reasonable wear and tear and Tenant 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 Laws and Restrictions and shall, at Tenant's
own expense obtain and maintain in effect all permits, licenses and the like
required by applicable law, all to the extent necessitated by Tenant's (or any
of its employee's, invitee's or customer's) particular use of the Premises, as
opposed to "office use" generally which will be the responsibility of Landlord
and the cost for which shall be included in Operating Expenses, subject to the
terms of Section 8.2. 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 or Office Park, including the
Premises, by Tenant, Tenant's contractors or Tenant's agents, employees,
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. Tenant shall pay Landlord, as additional rent, the
cost of Landlord (or its agents) either performing, or entering into a contract
for, regularly scheduled (monthly or quarterly as reasonably determined by
Landlord) preventive maintenance/service for the supplemental HVAC system and
equipment serving Tenant's computer room; provided that during the first Lease
Year, Tenant shall not be required to pay for any repairs or replacements
relating to the supplemental HVAC system, except for such preventative
maintenance/service and/or incidental repairs and replacements relating thereto
(e.g., filters, hoses and other de minimis items).

     6.4.2. 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
fails, refuses or neglects to commence such repairs and complete the same with
reasonable dispatch after such demand, Landlord may (but shall not be obligated
to) 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. 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 fail to so reimburse Landlord upon demand, Landlord shall
have the remedies provided for the nonpayment of rent or other charges payable
hereunder.

6.5. FLOOR LOAD - HEAVY MACHINERY; OCCUPANT DENSITY.

     6.5.1. Tenant shall not place a load upon any floor in the Premises
exceeding the floor load per square foot of area which such floor was designed
to carry and which is allowed by law. Landlord reserves the right to prescribe
the weight and position of all business machines and mechanical equipment,
including safes, which shall be placed so as to distribute the weight. Business
machines and mechanical equipment shall be placed and maintained by Tenant at
Tenant's expense in settings

                                       14

<PAGE>

sufficient, in Landlord's judgment, to 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, which shall not be unreasonably withheld, conditioned or delayed.

     6.5.2. 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 require for the
convenience of the normal operations of the Building.

     6.5.3. Tenant shall maintain a ratio of not more than one Occupant (as
defined below) for each two hundred (200) square feet of rentable area in the
Premises. Landlord shall have the right to periodically visit the Premises
without advance notice to Tenant in order to track the number of Occupants
arriving at the Premises, provided, however, Landlord shall use commercially
reasonable effort so as not to materially interfere with Tenant's business
operations during any such visit. For purposes of this section, "Occupants"
include employees, visitors, and contractors, but shall use commercially
reasonable effort so as to not materially include people not employed by Tenant
that deliver or pick up mail or other packages at the Premises, employees of
Landlord or employees of Landlord's agents or contractors. Tenant acknowledges
that increased numbers of Occupants causes additional wear and tear on the
Premises and the Common Areas, additional use of electricity, water and other
utilities, and additional demand for other Building services.

7.   SERVICES; UTILITY CHARGES

7.1. LANDLORD'S SERVICES.

     7.1.1. Landlord covenants during the Term:

     (a)  To furnish, through Landlord's employees or independent contractors,
          electricity (for lights, convenience receptacles, and normal office
          machines and equipment in the Premises, subject to Section 7.2 below,
          and for the common areas and facilities), heat, air conditioning and
          ventilation and nightly janitorial and general cleaning services to a
          level customarily provided by operators of buildings such as the
          Building; it is understood, however, that heat, air conditioning and
          ventilation and certain other services shall only be furnished during
          Normal Building Operating Hours; and

     (b)  To furnish, through Landlord's employees or independent contractors,
          additional Building operation services upon reasonable advance request
          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 additional services as additional rent upon demand by
          Landlord.

     7.1.2. Landlord has made arrangements for the operation of a cafeteria food
service facility (the "Cafeteria") in the Building. The Cafeteria will be
available for use by Tenant and its employees, together with others, during its
hours of operation and in accordance with any rules and regulations that may be
established concerning such use. Charges for food and other services provided at
the Cafeteria shall be as determined by Landlord (or the operator of the
Cafeteria) from time to time in its sole

                                       15

<PAGE>

discretion. It is understood and agreed that all use of the Cafeteria and its
facilities shall be at the sole risk of Tenant and the employees using same, and
Tenant hereby releases Landlord, and the owner or operator of the Cafeteria,
from any liability in connection with such use and indemnifies and holds the
Landlord, and the owner or operator of the Cafeteria, harmless from and against
any loss, cost, liability, damage or expense occasioned by or in any way
related to or arising from the use of the Cafeteria by Tenant or Tenant's
employees or by any other party allowed to use same by Tenant or any of its
employees. Landlord reserves the right at any time or from time to time, in its
sole discretion, to discontinue the Cafeteria, or alter its size, type, location
or serving capacity, or its meals or hours of operation or any other aspect
thereof. Any losses incurred by Landlord in operating the Cafeteria shall be
included as part of the Operating Expenses for the Operating Year in which such
losses were incurred.

     7.1.3. All costs incurred by Landlord in connection with foregoing services
shall be included as part of the Operating Expenses.

7.2. UTILITY SERVICES AND CHARGES.

     7.2.1. The Tenant shall obtain directly from the supplier or utility
company any services (such as telephone service, or should it be separately
metered and provided as provided in Section 7.3 below, electrical service) not
provided to the Premises by Landlord, and Tenant shall pay all charges therefor
when due. If requested by Landlord, Tenant shall promptly 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 Fixed 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 charges when
due. Landlord shall hold the amounts from time to time deposited under this
Section 7.2 as security for payment of such charges and may, without limitation
of remedies on account of Tenant's failure to make any subsequent payment of
such 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.

     7.2.2. Tenant shall not introduce to the Premises fixtures or equipment
which (individually or in the aggregate) exceed those used by the average office
tenant or overload the capacity of the electrical, heating, ventilating and air
conditioning, mechanical, plumbing or other utility systems serving the
Premises; such capacities shall be deemed overloaded if such use by Tenant
exceeds, on a square foot basis, the capacity of such systems; and in no event
shall the electrical usage at the Premises exceed 4 watts per square foot. If
Tenant uses the Premises or installs fixtures or equipment in such a manner as
would so overload said systems, as reasonably determined by Landlord, Tenant
shall pay, as additional rent, within 10 days of billing therefor, the cost of
providing and installing any additional equipment, facilities or services that
may be required as a result thereof, and for any repairs or damage resulting
therefrom. Landlord acknowledges that the current use by Tenant of the Premises
is permitted under this Section.

     7.2.3. All costs incurred by Landlord in connection with utility services
provided to the Premises shall be included as part of the Operating Expenses,
subject to the terms of Section 8.2.

     7.2.4. Landlord shall not be responsible for any interruption of
electricity, oil, water, sewer, telephone, data or other utility or Building
services supplied to the Premises. Furthermore, Landlord shall not be liable for
loss of property or for injury to, or interference with, Tenant's business,
including, without limitation, loss of profits, however occurring, through or in
connection with or incidental to an

                                       16

<PAGE>

interruption of any such services or utilities. Landlord may comply with
voluntary controls or guidelines promulgated by any governmental entity relating
to the use or conservation of energy, water, gas, light or electricity or the
reduction of automobile or other emissions without creating any liability of
Landlord to Tenant under this Lease.

7.3. ELECTRICAL SERVICE AND ELECTRICAL CHARGE.

     7.3.1. It is understood that the electrical service for the Premises (for
lights and convenience outlets) is currently separately metered from service
provided to other rentable spaces and common areas of the Building. Accordingly,
(i) Tenant shall make arrangements for such electrical service directly with the
utility supplier, and (ii) Landlord shall have no obligations to Tenant with
respect to electrical service to the Premises.

     7.3.2. Nothing in Section 7.3.1 shall relieve Tenant from its obligation to
pay as part of Operating Expenses, Tenant's share of electrical charges relating
to the common areas as set forth in this Lease.

     7.3.3. Intentionally Deleted.

8.   ADDITIONAL RENT FOR TAXES AND OPERATING EXPENSES

8.1. TENANT'S PAYMENT OF ITS SHARE OF REAL ESTATE TAXES.

     8.1.1. For the purposes of this Section, the following terms shall have the
following meaning:

               "Tax Year" shall mean the twelve-month period in use in the Town
of Burlington for the purpose of imposing ad valorem taxes upon real property.
In the event that such Town changes the period of its tax year, "Tax Year" shall
mean a twelve-month period commencing on the first day of such new tax year, and
each twelve-month period commencing on the anniversary of such date during the
Term of this Lease.

               "Taxes" shall mean all taxes and assessments of every kind and
nature imposed, assessed or levied by a governmental authority on the Property,
including without limitation all real estate taxes, betterments, assessments
(ordinary and extraordinary), water rents, sewer, and other charges. If taxes
upon rentals or otherwise pertaining to the Property (including without
limitation any tax on rentals or income or any value added tax, so called) shall
be substituted, in whole or in part, for the present ad valorem real estate
taxes, or shall be assessed in addition thereto, then the term "Taxes" shall
include such substituted taxes, to the extent to which the same shall be a
substitute for present ad valorem real estate taxes, together with any such
additional taxes. The term "Taxes" shall not include any inheritance or estate
taxes, or any taxes on income to the extent applicable to Landlord's net income.
Landlord acknowledges that the Building and improvements relating thereto are
the only taxable improvements located on the Lot.

     8.1.2. In the event that the Taxes imposed with respect to the Property
shall be greater during any Tax Year (and in the event the Town shall first send
estimated tax bills, until a final bill is sent [at which time Tenant's share of
real estate taxes shall be recomputed], real estate taxes shall be such taxes as
shown on the estimated tax bill) than the Tax Base (as defined in Section 1.2),
Tenant shall pay to Landlord, as additional rent, the amount obtained by
multiplying the amount by which the Taxes exceed the Tax Base by a fraction, the
numerator of which is the Rentable Floor Area of the Premises and the
denominator of which is the Rentable Floor Area of the Building.

                                       17

<PAGE>

     8.1.3. Landlord shall submit to Tenant a statement setting forth the amount
of such additional rent, and within 30 days after the delivery of such statement
(whether or not such statement shall be timely), Tenant shall pay to Landlord
the payment under subparagraph 8.1.2 above. So long as the Taxes, or any portion
thereof, shall be payable in installments, 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.

     8.1.4. If the first day of the Tax Year in such Town of Burlington should
be changed after the Commencement Date so as to change the twelve-month period
comprising the Tax Year, or if the Tax Year shall be a period of time other than
twelve months, in determining the additional rent to be paid by Tenant under
this Section with respect to the Taxes payable by Tenant for any such Tax Year,
including a partial Tax Year, the Tax Amount shall be pro-rated on a per day
basis.

     8.1.5. Any betterment assessment, so-called "rent tax" or any other tax
levied or imposed by any governmental authority in addition to, in lieu of or as
a substitute for real estate taxes, shall nevertheless be deemed to be real
estate taxes for the purpose of this Section, provided, however, any such
amounts shall be payable by Tenant as if Landlord had elected to pay over the
longest period permitted by law.

     8.1.6. Tenant's obligations to pay additional rent under this Section on
account of Taxes shall commence on the Commencement Date.

     8.1.7. If Tenant is obligated to pay any additional rent as aforesaid with
respect to any Tax Year 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
Year, estimated monthly tax escalation payments equal to 1/12 of the annualized
amount of additional rent payable hereunder for said previous Tax Year (or as
otherwise reasonably estimated by Landlord). Estimated monthly tax escalation
payments for each ensuing Tax Year shall be made retroactively to the first day
of the Tax Year in question.

     8.1.8. In the event that Landlord obtains an abatement, reduction or refund
of any Taxes for a Tax Year which Tenant was obligated to pay a share of the
increase in Taxes, then Tenant shall receive as a credit against its payment
obligations under this Section, its proportionate share of the net proceeds of
such abatement, reduction or refund (after deduction of all reasonable costs,
including legal and appraisal fees, incurred by Landlord in obtaining the same)
but only to the extent and not in excess of any payments made by Tenant for such
increase as required under this Section. Landlord shall be under no obligation
to seek such an abatement, reduction or refund. To the extent same are not
credited as aforesaid, any of Landlord's reasonable costs (including legal and
appraisal fees) incurred in attempting to obtain an abatement, reduction or
refund shall be deemed Operating Expenses hereunder. Tenant shall not contest by
any proceedings the assessed valuation of Landlord's Property or any part
thereof for purposes of obtaining a reduction of its assessment or of any taxes.

     8.1.9. Tenant shall pay prior to delinquency all taxes assessed against and
levied upon trade fixtures, furnishings, equipment (other and all other personal
property of Tenant but not the Modular Furniture) contained in the Premises or
related to Tenant's use of the Premises. If any of Tenant's personal property
shall be assessed with Landlord's real or personal property, Tenant shall pay to
Landlord the taxes attributable to Tenant within ten (10) days after receipt of
a written statement from Landlord setting forth the taxes applicable to Tenant's
property.

8.2. TENANT'S PAYMENT OF ITS SHARE OF OPERATING EXPENSES,

     8.2.1. For the purposes of this Section, the following terms shall have the
following meanings:

                                       18

and said common areas, or either; reasonable reserves for the replacement of
equipment contained in and/or used in connection with the operation of the

otherwise consistent with generally accepted accounting principles), properly
attributable to the Operating Year in question, of the cost, with interest
thereon at a rate reasonably determined by Landlord, of any capital repairs,
improvements or replacements made to the Building or the Property, by Landlord
which, with respect to capital improvements, are anticipated to result in a
reduction in (or minimize increases in) Operating Expenses or are required under
any governmental law or regulation not applicable to the Building as of the
Commencement Date; and a commercially reasonable management fee based on a
percentage of the gross rentals of the Building. The Operating Expenses shall
also include the Building's share (as reasonably determined and allocated by
Landlord; which determination(s) and/or allocation(s) shall not materially
change during the Term unless the factor(s) on which such determination or
allocation change(s)) of: (i) the costs incurred by Landlord in operating,
maintaining, repairing, insuring and paying real estate taxes upon any common
facilities of the Office Park (including, without limitation, the common
facilities from time to time serving the Lot or Building in common with other
buildings or parcels of land), such as any so-called "loop" access roads,
retention ponds, sewer and other utility lines, amenities and the like; (ii)
shuttle bus service (if and so long as Landlord shall provide the same); (iii)
the actual or imputed cost of the space occupied by on-the-grounds building

     8.2.2. If, during any Operating Year (including the Operating Year used for
determining the Base Operating Expenses), less than 95% of the rentable area of
the Building is occupied, those Operating Expenses, the cost of which vary by
occupancy, shall be equitably adjusted by Landlord, on an item by item basis, as
appropriate, to reflect Operating Expenses based on 95% occupancy.

     8.2.3. In determining the Base Operating Expenses, there shall be excluded
from the Operating Expenses for said Operating Year any non-recurring capital
expenditures.

     8.2.4. After the expiration of each Operating Year, Landlord shall furnish
Tenant with a statement setting forth, in reasonable detail, 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.

     8.2.5. In the event the Operating Expenses during any Operating Year shall
be greater than the Base Operating Expenses (as defined in Section 1.2), Tenant
shall pay to Landlord, as additional rent, the amount obtained by multiplying
the amount by which the Operating Expenses exceed the Base Operating Expenses by
a fraction, the numerator of which is the Rentable Floor Area of the Premises
and the denominator of which is the Rentable Floor Area of the Building.

     8.2.6. Said additional rent shall, with respect to the Operating Years in
which the Commencement Date and end of the Term of this Lease fall, be pro-rated
on a per day basis. If Landlord shall change its Operating Year, appropriate
adjustment shall be made for any Operating Year less than or greater than
twelve-months which may result.

     8.2.7. Any additional rent payable by Tenant under this Section shall be
paid within 30 days after Landlord has furnished Tenant with the statement
described above.

     8.2.8. Tenant's obligations to pay additional rent under this Section on
account of Operating Expenses shall commence on the Commencement Date.

     8.2.9. If with respect to any Operating Year or fraction thereof during the
Term, Tenant is obligated to pay any additional rent as aforesaid, then Tenant
shall pay, as additional rent, on the first day of each month of the next
ensuing Operating Year, estimated monthly operating escalation payments equal to
l/12th of the amount of additional rent payable hereunder for said previous
Operating Year (or as otherwise reasonably estimated by Landlord). Estimated
monthly operating escalation payments for each ensuing Operating Year shall be
made retroactively to the first day of the Operating Year in question.

     8.2.10. Landlord shall permit Tenant, at Tenant's expense and during normal
business hours, but only one time with respect to any Operating Year, to review
Landlord's invoices and statements relating to the Operating Expenses for the
applicable Operating Year for the purpose of verifying the Operating Expenses
and Tenant's share thereof; provided that notice of Tenant's desire to so review
is given to Landlord not later than 30 days after Tenant receives an annual
statement from Landlord, and provided that such review is thereafter commenced
and prosecuted by Tenant with due diligence. Any Operating Expenses statement or
accounting by Landlord shall be binding and conclusive upon Tenant unless (i)
Tenant duly requests such audit within such 30-day period, and (ii) within 3
months after such audit request, Tenant shall notify Landlord in writing that
Tenant disputes the correctness of such statement, specifying the particular
respects in which the statement is claimed to be incorrect. Tenant shall have no
right to conduct a review or to give Landlord notice that it desires to conduct
a review at any time Tenant is in default under the Lease. The accountant
conducting the review shall be compensated on an hourly basis and shall not be
compensated based upon a percentage of overcharges it discovers. No subtenant
shall have any right to conduct a review, and no assignee shall conduct a review
for any period during

                                       21

<PAGE>

which such assignee was not in possession of the Premises. Tenant agrees that
the results of any Operating Expense review shall be kept strictly confidential
by Tenant and shall not be disclosed to any other person or entity.

9.   INDEMNITY AND INSURANCE

9.1. INDEMNITY.

     9.1.1. Except for the negligence or willful misconduct of Landlord (or
those for whom Landlord is legally responsible), to the maximum extent this
agreement may be made effective according to law, Tenant shall indemnify and
save harmless Landlord (together with its officers, directors, stockholders,
partners, beneficial owners, trustees, managers, members, employees, agents,
contractors, attorneys, and mortgagees) from and against all claims of whatever
nature arising from: (i) any act, omission or negligence of Tenant, or Tenant's
contractors, licensees, invitees, agents, servants or employees ("Tenant's
Agents"), or any default or failure to perform an obligation (after applicable
notice and cure periods) by Tenant hereunder; or (ii) any accident, injury,
damage or loss whatsoever caused to any person or property during the Term, and
thereafter, so long as Tenant is in occupancy of any part of the Premises, and
occurring in the Premises, or arising out of the use and occupancy of the
Premises by Tenant and Tenant's Agents; or (iii) any accident, injury, damage or
loss occurring outside of the Premises, where such accident, injury, damage or
loss results or is claimed to have resulted from the act, omission or negligence
of Tenant or Tenant's Agents. Tenant's obligations hereunder shall include any
other matters for which Tenant has agreed to indemnify Landlord pursuant to any
other provision of this Lease.

     9.1.2. This indemnity and hold harmless agreement shall include indemnity
against all reasonable costs, expenses and liabilities incurred in or in
connection with any such claim or proceeding brought thereon and providing a
defense, with counsel reasonably satisfactory to Landlord, at Tenant's sole
expense, within ten (10) days after written demand from Landlord, of any claims,
action or proceeding arising out of or relating hereto whether or not litigated
or reduced to judgment and whether or not well founded.

9.2. INSURANCE.

     9.2.1. Tenant shall obtain and keep in force and effect during the Term, at
its own cost and expense, commercial general liability and property damage
insurance, on an occurrence basis, including a special form commercial general
liability endorsement, a contractual liability endorsement, and host liquor
liability coverage if Tenant serves or allows to be served any alcoholic
beverages on or about the Premises, such insurance to afford protection in an
amount of not less than $5,000,000 for injury, death, property damage or other
loss arising out of any one occurrence, protecting Tenant as insured, and naming
Landlord, Landlord's mortgagees, property managers and managing agents as
additional insureds, against any and all claims for bodily injury, personal
injury, death, property damage or other loss occurring in, upon, adjacent to or
connected with the Premises or any part thereof and contain the "Amendment of
the Pollution Exclusion" for damage caused by heat, smoke or fumes from a
hostile fire. The policy shall not contain any intra-insured exclusions as
between insured persons or organizations, but shall include coverage for
liability assumed under this Lease as an "insured contract" for the performance
of Tenant's indemnity obligations under this Lease. Landlord may from time to
time during the Term increase the coverages required of Tenant hereunder to that
customarily carried in the area in which the Premises are located on property
similar to the Premises.

                                       22

<PAGE>

     9.2.2. Tenant further agrees to maintain: (i) workers' compensation and
employers' liability insurance with a limit of liability as required by law to
be maintained; and (ii) so called "Special Form" insurance coverage for all of
its contents, furniture, furnishings, equipment, improvements, fixtures and
personal property located at the Premises providing protection in an amount
equal to one hundred percent (100%) of the replacement cost basis of said items,
containing commercially reasonable deductibles. If this Lease is terminated as
the result of a casualty in accordance with Section 11, the proceeds of said
insurance attributable to the replacement of all tenant improvements installed
at the Premises by Landlord or at Landlord's cost shall be paid to Landlord.

     9.2.3. The insurance required hereunder shall be written in form and
substance satisfactory to Landlord by a good and solvent insurance company of
recognized standing, admitted to do business in Massachusetts, with a general
policyholder's rating of not less than A- and financial rating of not less than
Class XIII (as rated in the most current Best's Insurance Reports), which
company shall be reasonably satisfactory to Landlord. Tenant shall procure,
maintain and place such insurance and pay all premiums and charges therefor, and
upon failure to pay all premiums and charges (and without limiting any other
remedies on account thereof), Landlord may, but shall not be obligated to,
procure, maintain and place such insurance or make such payments, and in such
event, Tenant agrees to pay the amount thereof to Landlord on demand, as
additional rent hereunder.

     9.2.4. Tenant shall cause to be included in all such insurance policies a
provision to the effect that the same will be non-cancelable except upon 30 days
written notice to Landlord. Prior to the Commencement Date, certificates of
insurance shall be deposited with the Landlord. Any renewals, replacements and
endorsements shall also be deposited with Landlord, in the case of renewals,
same shall be so deposited at least 30 days prior to the expiration of the prior
policy.

9.3. TENANT'S RISK.

To the maximum extent this Agreement may be made effective according to law,
Tenant agrees its use and occupancy of the Premises shall be at Tenant's sole
risk; and Landlord shall have no responsibility or liability for any loss of or
damage to furniture, fixtures, equipment or other personal property of Tenant
for any reason whatsoever; and Landlord shall not be responsible or liable for
any loss or damage resulting to Tenant or those claiming by, through or under
Tenant, or its or their property, from the breaking, bursting, stopping or
leaking of electric cables and wires, water, gas, sewer or steam pipes,
sprinklers, and from roof leaks and the like. 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.

9.4. 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 any third parties, including
without limitation 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.

9.5. LANDLORD'S INSURANCE.

During the Term, Landlord shall secure and carry a policy of insurance covering
the Building for direct risk of physical loss in such coverage amounts and
values as Landlord (or its Lender) shall deem necessary or appropriate in its
sole but reasonable discretion, the cost for which shall be included in

                                       23

<PAGE>

Operating Expenses.

10.  LANDLORD'S ACCESS TO PREMISES

10.1. LANDLORD'S RIGHT OF ACCESS.

Upon reasonable advance notice to Tenant (except in case of emergency in which
event no such notice shall be required), Landlord shall have the right 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 (or to the
Building), and Landlord shall also have the right to make access available at
all reasonable hours to prospective or existing mortgagees or purchasers of any
part of the Building. Any such entry shall be made in a manner so as to minimize
unreasonable interference with Tenant's business operations.

10.2. EXHIBITION OF SPACE TO PROSPECTIVE TENANTS.

For a period of 12 months prior to the expiration of the Lease Term, and during
any period in which Landlord is considering exercising its recapture rights (as
provided in Section 5.2), or after Landlord has exercised same, and upon
reasonable advance notice to Tenant, 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.

10.3. KEYS.

Landlord shall have the right to retain keys and electric codes or card keys to
the locks and card key access systems and other security systems on the entry
doors to the Premises and all interior doors at the Premises.

11.  FIRE, EMINENT DOMAIN, ETC.

11.1. FIRE OR OTHER CASUALTY.

     11.1.1. If the Premises or the Building are damaged in whole or in part by
any fire or other casualty (a "casualty"), with respect to the Premises only,
Tenant shall immediately give notice thereof to the Landlord. Unless this Lease
is terminated as provided herein, the Landlord, at its own expense (except for
any insurance deductibles, which shall be deemed Operating Expenses in
accordance with Section 8.2), and proceeding with due diligence and all
reasonable dispatch, but subject to delays beyond the reasonable control of
Landlord, shall repair and reconstruct the same so as to restore the Premises
(but not any alterations or additions made by or for Tenant or any trade
fixtures, equipment or personal property of Tenant) to substantially the same
condition they were in prior to the casualty, subject to zoning and building
laws then in effect. Notwithstanding the foregoing, in no event shall Landlord
be obligated either to repair or rebuild if the damage or destruction results
from an uninsured casualty or if the costs of such repairing or rebuilding
exceeds the amount of the insurance proceeds (net of all costs and expenses
incurred in obtaining same) received by Landlord on account thereof. Landlord
shall not be liable for any inconvenience or annoyance to Tenant or injury to
the business of Tenant resulting from delays in repairing such damage. If such
damage or destruction occurs as a result of the negligence or the intentional
acts of Tenant or Tenant's employees, agents, contractors or invitees, and the
proceeds of insurance which are actually received by Landlord are not sufficient
to pay for the repair of all of the damage, Tenant shall pay, at Tenant's sole
cost and expense, to Landlord upon demand, the difference between the cost of
repairing the damage and the insurance proceeds received by Landlord.

                                       24

<PAGE>

     11.1.2. The Landlord shall, within 45 days after the occurrence of a
casualty, provide Tenant with a good faith estimate of the time required to
repair the damage to the Premises or the Building, as provided herein; if such
estimate is for a period of more than 180 days from the occurrence of the
casualty (or during the last 18 months of the Term, for a period of more than 90
days), the Premises shall be deemed "substantially damaged". If the Premises or
the Building are substantially damaged, Landlord may elect to terminate this
Lease by giving Tenant written notice of such termination within 60 days of the
date of such casualty; and if the Premises or the Building are substantially
damaged, and if as a result the Premises are rendered untenantable for the
Permitted Use, or, if, in fact, the Premises are not so repaired within the
estimated time period, then Tenant may terminate this Lease by giving Landlord
written notice of such termination within 60 days of the date of such casualty,
or within 30 days of the expiration of such estimated time period.

     11.1.3. For so long as such damage results in material interference with
the operation of Tenant's use of the Premises which material interference causes
Tenant to be unable to use the Premises, the Fixed Rent and additional rent
payable by Tenant shall abate or be reduced proportionately for the period,
commencing on the day following such material interference and continuing until
the Premises has been substantially restored. Notwithstanding the foregoing, if
such casualty was due to the fault or neglect of Tenant or Tenant's employees,
contractors or agents, such abatement or reduction shall be made only if and to
the extent of any proceeds of rental interruption insurance actually received by
Landlord and allocated to the Premises.

     11.1.4. If the Premises are damaged by a casualty, and the Lease is not
terminated as provided herein, the Tenant, at its own expense, and proceeding
with all reasonable dispatch, shall repair and reconstruct all of the
improvements, alterations and additions made to the Premises by Tenant, and any
trade fixtures, equipment or personal property of Tenant which shall have been
damaged or destroyed and the Modular Furniture.

11.2. EMINENT DOMAIN.

     11.2.1. In the event of any condemnation or taking in any manner for public
or quasi-public use, which shall be deemed to include a voluntary conveyance in
lieu of a taking (a "taking") of the whole of the Property, this Lease shall
forthwith terminate as of the date when Tenant is required to vacate the
Premises.

     11.2.2. Unless this Lease is terminated as provided herein, the Landlord,
at its own expense, and proceeding with due diligence and all reasonable
dispatch, but subject to delays beyond the reasonable control of Landlord, shall
restore the remaining portion of the Premises (but, not any alterations or
improvements made by or for Tenant, or any trade fixtures, equipment or personal
property of Tenant or the Modular Furniture) and the necessary portions of the
Property as nearly as practicable to the same condition as it was prior to such
taking, subject to zoning and building laws then in effect. Notwithstanding the
foregoing, Landlord's obligation to restore the remaining portion of the
Premises shall be limited to the extent of the condemnation proceeds (net of all
reasonable costs and expenses incurred in connection with same) received by
Landlord on account thereof. Landlord shall not be liable for any inconvenience
or annoyance to Tenant or injury to the business of Tenant resulting from delays
in restoring the Premises.

     11.2.3. In the event that only a part of the Premises or the Property shall
be taken, then, if such taking is a substantial taking (as hereinafter defined),
either Landlord or Tenant may by delivery of notice in writing to the other
within 60 days following the date on which Landlord's title has been divested by
such authority, terminate this Lease, effective as of the date when Tenant is
required to vacate any portion

                                       25

<PAGE>

of the Premises or appurtenant rights. A "substantial taking" shall mean a
taking which: requires restoration and repair of the remaining portion of the
Property that cannot in the ordinary course be reasonably expected to be
repaired within 180 days; results in the loss of reasonable access to the
Premises; results in the loss of more than 25% of the rentable floor area of the
Premises; or results in loss of parking or of facilities in the Building and
Landlord reasonably determines it is not practical to relocate such parking or
relocate and reconnect such facilities within the remaining Building or
Property.

     11.2.4. If this Lease is not terminated as aforesaid, then this Lease shall
continue in full force and effect, provided if as a result of which there is
material interference with the operation of Tenant's use of the Premises, then
the Fixed Rent and additional rent payable by Tenant shall be justly and
equitably abated and reduced according to the nature and extent of the loss of
use thereof suffered by Tenant.

     11.2.5. Landlord shall have and hereby reserves and excepts, and Tenant
hereby grants and assigns to Landlord, all rights to recover for damages to the
Building, the Lot, and the leasehold interest hereby created (including any
award made for the value of the estate vested by this Lease in Tenant), and to
compensation accrued or hereafter to accrue by reason of such taking, 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 of
compensation. Nothing contained herein shall be construed to prevent Tenant from
prosecuting in any condemnation proceedings a separate claim for the value of
any of Tenant's personal property and for relocation expenses and business
losses, provided that such action shall not affect the amount of compensation
otherwise recoverable by Landlord from the taking authority.

12.  DEFAULT

12.1. TENANT'S DEFAULT.

The following shall be deemed to be defaults hereunder:

     (a)  Tenant's failure to pay Fixed Rent or monthly installments of
          additional rent or any other charges for which provision is made
          herein, on or before the seventh (7th) day after written notice from
          Landlord that such sums are overdue; or

     (b)  Intentionally omitted; or

     (c)  Tenant's failure to perform or observe any other covenants, terms or
          conditions contained in this Lease, which failure is not cured within
          30 days after written notice from Landlord thereof, or if such failure
          is of such character that Tenant cannot reasonably effect a cure
          within such 30-day period, Tenant shall fail to commence such remedy
          promptly and prosecute such remedy to completion with diligence and
          continuity within 60 days after the original notice from Landlord; or

     (d)  If the estate hereby created shall be taken on execution or by other
          process of law, or if Tenant shall be judicially declared bankrupt or
          insolvent according to law, or if any assignment shall be made of the
          property of Tenant for the benefit of creditors, or if a receiver,
          guardian, conservator, trustee in involuntary bankruptcy or
          other-similar officer shall be appointed to take charge of all or any
          substantial part of Tenant's property by a court of competent
          jurisdiction, or if a petition shall be filed for the reorganization
          of Tenant under any provisions of the Bankruptcy Code now or hereafter
          enacted or if Tenant shall file a petition for such reorganization or
          for arrangements under any provision of the Bankruptcy Code now or
          hereafter enacted and providing a plan for a debtor to settle, satisfy
          or extend the time for payment of debts (references herein to

                                       26

<PAGE>

          Tenant shall include any guarantor of Tenant's obligations hereunder);
          or

     (e)  The discovery by Landlord that any financial statement given to
          Landlord by Tenant, or by any guarantor of Tenant's obligations
          hereunder, was materially false at the time given. Tenant acknowledges
          that Landlord has entered into this Lease in material reliance on such
          information; or

     (f)  If Tenant is a corporation or a partnership, the dissolution or
          liquidation of Tenant (except in the event of a transaction pursuant
          to Section 5.3.3 above); or

     (g)  If Tenant's obligations under this Lease are guaranteed: (i) the death
          of a guarantor, (ii) the termination of a guarantor's liability with
          respect to this Lease other than in accordance with the terms of such
          guaranty, (iii) a guarantor's becoming insolvent or the subject of a
          bankruptcy filing, (iv) a guarantor's refusal to honor the guaranty,
          or (v) a guarantor's breach of its guaranty obligation on an
          anticipatory breach basis.

12.2. REMEDIES.

     12.2.1. In the event any default shall occur (notwithstanding any license
of a former breach of covenant or waiver of the benefit hereof or consent in a
former instance), Landlord lawfully may, immediately or at any time thereafter,
and without demand or notice, but otherwise in accordance with Law: 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
through or under Tenant and remove its or their effects without being 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, with
or without making such entry as aforesaid, Landlord shall have the right, by
suitable notice to Tenant, forthwith to terminate this Lease.

     12.2.2. Tenant covenants and agrees, notwithstanding any entry or re-entry
by Landlord, whether by summary proceedings or otherwise, and notwithstanding
any such termination, to pay and be liable for, on the days originally fixed
herein for the payment thereof, amounts equal to the several installments of
rent and other charges reserved as they would, under the terms of this Lease,
become due 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, and
for the whole thereof. Landlord agrees to use commercially reasonable efforts to
relet the Premises after any such termination so as to mitigate Tenant's damages
hereunder; provided, however, Landlord shall not be liable for, nor shall
Tenant's obligations hereunder be diminished or reduced because of Landlord's
failure to relet the Premises or to collect rent due for such reletting despite
such reasonable efforts and such reletting efforts shall be subject to (a)
through (d) in the following sentence. Tenant acknowledges that Landlord shall
have no obligation to lease the Premises (a) in any particular order while there
is any other vacant space in the Building or other buildings in owned, operated
or managed by Landlord or an affiliated party, (b) to a potential tenant which
does not satisfy Landlord's criteria for a credit worthy tenant, (c) to a
potential tenant whose business or business related activities may violate or
conflict with any applicable Laws and Restrictions or other leases relating to
the Building, (d) to a potential tenant which may have an adverse impact upon
the high-grade manner in which the Building is operated as determined by
Landlord in good faith. In the event the Premises be relet by Landlord, Tenant
shall be entitled to a credit in the net amount of rent and other charges
received by Landlord in reletting, after deduction of all good faith expenses
incurred in reletting the premises (including, without limitation, remodeling
and repair costs, brokerage fees, advertising costs, inspection fees, free rent
and rental

                                       27

<PAGE>

concessions, tenant allowances, and attorneys' fees and costs, and the like),
and in collecting the rent in connection therewith, in the following manner:

     Amounts received by Landlord after reletting shall first be applied against
     such Landlord's expenses, until the same are recovered, and until such
     recovery, Tenant shall pay, as of each day when a payment would fall due
     under this Lease, the amount which Tenant is obligated to pay under the
     terms of this Lease (Tenant's liability prior to any such reletting and
     such recovery not in any way to be diminished as a result of the fact that
     such reletting might be for a rent higher than the rent provided for in
     this Lease); when and if such expenses have been completely recovered, the
     amounts received from reletting by Landlord as have not previously been
     applied shall be credited against Tenant's obligations as of each day when
     a payment would fall due under this Lease, and only the net amount thereof
     shall be payable by Tenant. Further, amounts received by Landlord from such
     reletting for any period shall be credited only against obligations of
     Tenant allocable to such period, and shall not be credited against
     obligations of Tenant hereunder accruing subsequent or prior to such
     period, nor shall any credit of any kind be due for any period after the
     date when the term of this Lease is scheduled to expire according to its
     terms.

As an alternative, at the election of Landlord, 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 then value 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 fair market rental value (in
advance) of the Premises for the balance of the term. For the purposes of this
Section, if Landlord elects to require Tenant to pay damages in accordance with
this subsection, the total rent shall be computed by assuming that Tenant's
share of additional rent would be, for the balance of the unexpired term, the
amount thereof (if any) for the immediately preceding annual period payable by
Tenant to Landlord.

     12.2.3. Intentionally Omitted.

     12.2.4. 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 good
faith costs and expenses, including reasonable attorney's fees incurred by
Landlord in enforcing this Lease from and after Tenant's default.

12.3. INTEREST ON LATE PAYMENTS.

If any payment of Fixed Rent, additional 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) 12% 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.

12.4. 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 30 days, or such additional time as is reasonably
required to correct any such default, provided Landlord is diligently pursuing
any such correction, after notice by Tenant to Landlord properly specifying
wherein Landlord has failed to perform any such obligation. It is the express
understanding and agreement of the parties and a condition

                                       28

<PAGE>

of Landlord's agreement to execute this Lease that in no event shall Tenant have
the right to terminate this Lease or seek an abatement to or offset from Fixed
Rent or Additional Rent as a result of Landlord's default, but Tenant shall be
entitled to seek all other remedies, at law or equity, as a result of such
default. Tenant hereby waives its right to recover punitive or consequential
damages arising out of a Landlord default. Except for Tenant's monetary
obligations, this Lease and the obligations of either party hereunder shall not
be affected or impaired because the other party is unable to fulfill any of its
obligations hereunder or is delayed in doing so, if such inability or delay is
caused by reason of a Force Majeure Event, and the time for the other party's
performance shall be extended for the period of any such delay. Any claim,
demand, right or defense by Tenant that arises out of this Lease or the
negotiations which preceded this Lease shall be barred unless Tenant commences
an action thereon, or interposes a defense by reason thereof, within six (6)
months after the date of the inaction, omission, event or action that gave rise
to such claim, demand, right or defense. As used herein, a "Force Majeure Event"
shall be any delay caused by or resulting from acts of God, war, civil
commotion, fire, flood or other casualty, labor difficulties, shortages of or
inability to obtain labor, materials or equipment, government regulations,
unusually severe weather, or other causes beyond such party's reasonable
control.

12.5. COSTS OF ENFORCEMENT.

Landlord and Tenant shall each pay all reasonable costs and expenses (including
without limitation reasonable attorney's fees) incurred by the other party in
enforcing the other party's obligations or its rights under this Lease, provided
such other party prevails in enforcing such obligations or rights, such costs
not to accrue for the purposes hereof until the expiration of any notice and
cure period with respect to such default.

12.6. BANKRUPTCY AND INSOLVENCY.

If the estate created hereby shall be taken in execution, or by other process of
law, or if Tenant shall be declared bankrupt or insolvent, according to law, or
if any receiver be appointed for the business and property of Tenant, or if any
assignment shall be made of Tenant's property for the benefit of creditors (and
as to such matters involuntarily taken against Tenant, Tenant has not within
sixty (60) days thereof obtained a release or discharge therefrom), then this
Lease may be canceled at the option of Landlord. If, as a matter of law,
Landlord has no right upon the bankruptcy of Tenant to terminate this Lease
then, the rights of Tenant, as debtor, or its trustee, shall be deemed abandoned
or rejected unless Tenant, as debtor, or its trustee, (a) within sixty (60) days
after the date of the order for relief under Chapter 7 of the Bankruptcy Code or
sixty (60) days after the date the petition is filed under Chapter 11 of the
Bankruptcy Code assumes in writing the obligations under this Lease, (b) cures
or adequately assures the cure of all defaults existing under this Lease on
Tenant's part within such sixty (60) days, and (c) furnishes adequate assurance
of future performance of the obligations of Tenant under this Lease. Adequate
assurance of curing defaults means the posting with Landlord of a sum in cash
sufficient to defray the costs of such cure. Adequate assurance of future
performance of the Tenant's obligations under this Lease means increasing the
security deposit or letter of credit by an amount equal to six (6) Monthly
Installments of Fixed Rent.

Tenant shall not be permitted to assume and assign this Lease in connection with
any bankruptcy or insolvency proceedings without full and complete compliance
with the following provisions: (a) Landlord is provided with the following
information regarding the party desiring to assume the Lease ("Assumptor") which
Landlord in its sole and absolute discretion deems sufficient (a) organizational
information regarding the Assumptor (2) audited financial statements for the
three (3) most recent fiscal years, and (3) such other information as Landlord
deems appropriate, (b) Landlord determines that the use

                                       29

<PAGE>

of the Demised Premises by the intended Assignee is compatible with the
character of the Building, (c) all existing defaults under this Lease are cured
at least ten (10) days prior to any hearings in connection with Tenant's request
to assume and assign the Lease, (d) the Assumptor at any such hearing provides
adequate assurance of its future performance of the Lease as determined by
Landlord in its sole and absolute discretion, which adequately assurance shall
include at least the following: (1) posting of security deposit or letter of
credit equal to six (6) Monthly Installments of Fixed Rent, if such was not
already posted by Tenant, (2) paying in advance to Landlord the next six (6)
Monthly Installments of Fixed Rent, or posting an irrevocable letter of credit
for such amount, (3) establishing with Landlord an escrow in advance for the
full cost of all real estate taxes, and insurance, as required under the Lease
for the next twelve (12) months of the Lease and thereafter on an annual basis
in advance, and (4) providing Landlord with an unconditional continuing
guarantee of the Lease executed by the owners or officers of the Assumptor as
determined by Landlord in its sole and absolute discretion, and (5) the
Assumptor executes a written agreement assuming the Lease and such Lease
amendments as are necessary, which agreements and amendments are satisfactory to
Landlord in its sole and absolute discretion.

13.  MISCELLANEOUS PROVISIONS

13.1. EXTRA HAZARDOUS USE.

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

13.2. WAIVER.

     13.2.1. Failure on the part of either party 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 the first party of any of its rights hereunder.
Further, no waiver at any time of any of the provisions hereof by Landlord 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
to or of any action by Tenant requiring such consent or approval shall not be
construed to waive or render unnecessary Landlord's consent or approval to or of
any subsequent similar act by Tenant.

     13.2.2. 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.

13.3. COVENANT OF QUIET ENJOYMENT.

Tenant, upon payment of the rent and the observing, keeping and performing all
of the covenants, 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

                                       30

<PAGE>

hindrance or ejection by any persons lawfully claiming under Landlord to have
title to the Premises superior to that of Tenant, subject, however, to the
rights of the holders of mortgages on the Property, and subject to the terms
and conditions of this Lease. The foregoing covenant of quiet enjoyment is in
lieu of any other covenant, expressed or implied.

13.4. LANDLORD'S LIABILITY.

     13.4.1. It is understood and agreed that the obligations, covenants or
liabilities 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 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 and
their respective officers, directors, stockholders, partners, managers, members,
beneficial owners, trustees, employees, agents, contractors, attorneys, and
mortgagees), shall never be personally liable for any such 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) or not involving any claim in
monetary damages from Landlord's assets other than a claim limited to Landlord's
equity interest aforesaid in the Building. Notwithstanding any other provision
of this Lease to the contrary, in no event shall either party ever be liable for
any indirect, special or consequential damages suffered by the other or the
other's Agents from any cause whatsoever; provided, however, that the foregoing
limitation on damages shall in no event apply to Tenant's failure to comply
with, or breach of, Sections 13.21 and 13.23, in which event Landlord shall have
recourse to all rights and remedies available under this Lease, at law or equity
with no such limitation on damages.

     13.4.2. With respect to any services, including, without limitation,
electric current 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 Agents.

13.5. 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 default 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 Lease, the term "mortgage" includes a
mortgage on a leasehold interest of the Landlord (but not one on Tenant's
leasehold interest).

                                       31

<PAGE>

13.6. ASSIGNMENT OF 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 on which the
          same 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.

13.7. 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 or
encumbrance 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. If Tenant shall fail to so discharge
such lien or encumbrance then, in addition to any other right or remedy of
Landlord, Landlord may, but shall not be obligated to, discharge same (either
by payment or by filing of the necessary bond or otherwise) and any amount paid
by Landlord for any of the aforesaid purposes, and all actual and legal and
other expenses of Landlord, including reasonable counsel fees, in or about
procuring the discharge of such lien, together with all necessary disbursements
in connection therewith, and together with interest thereon at the rate set
forth in Section 12.3 from the date of payment, shall be repaid by Tenant to
Landlord on demand, and if unpaid may be treated as additional rent.

13.8. NO BROKERAGE.

Each party warrants and represents that it has not dealt with any broker other
than the Brokers, named in Section 1.2 hereof, in connection with the
consummation of this Lease, and in the event any claim is made against the
Landlord or the Tenant relative to dealings with brokers other than the Brokers,
the party breaching such warranty and representation shall defend the claim
against the first party with counsel of the indemnified party's selection and
save harmless and indemnify such party on account of loss, cost or damage which
may arise by reason of any such claim.

                                       32

<PAGE>

13.9. INVALIDITY OF PARTICULAR PROVISIONS.

If any term or provision of this Lease or the application thereof to and 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.

13.10. 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. 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 Section 5 hereof.

13.11. RECORDING.

Tenant agrees not to record the within Lease, but, if required by applicable law
in order to protect Tenant's interest in the Premises, each party hereto agrees,
on the request of the other, to execute a so-called memorandum of lease or short
form lease in recordable form 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.

13.12. 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 deemed duly
given if sent either (i) by registered or certified mail, postage prepaid,
return receipt requested, or (ii) by overnight mail service as provided by the
U.S. mail or by a nationally recognized private common carrier with provisions
for receipt of delivery, or (iii) by hand with a written acknowledgement of
receipt (or refusal thereof), and addressed as follows:

     (a)  If intended for Landlord, addressed to Landlord at the Present
          Mailing Address of Landlord (as set forth in Section 1.2 of this
          Lease) with a copy to Sherin and Lodgen LLP, 101 Federal Street,
          Boston, MA 02110 Attn: Robert M. Carney (or to such other address or
          addresses as may from time to time hereafter be designated by Landlord
          by like notice).

     (b)  If intended for Tenant: if given prior to the Commencement Date,
          addressed to Tenant at the Present Mailing Address of Tenant (as set
          forth in Section 1.2 of this Lease); and if given after the
          Commencement Date, addressed to Tenant at the Premises, with a copy
          to _________________________________, ____________________________,
          Attention: ______________________________________________________ (or
          to such other address or addresses as may from time to time hereafter
          be designated by Tenant by like notice).

                                       33

<PAGE>

All such notices shall be effective when delivered in hand (or when refused), or
when deposited in the United States mail within the continental United States or
when sent by overnight mail.

13.13. 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 or
Tenant shall alter, change or modify any of the provisions hereof.

13.14. PARAGRAPH HEADINGS.

The section and 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. This Lease shall be interpreted as
if it was prepared by both parties and ambiguities shall not be resolved in
favor of Tenant because all or a portion of this Lease was prepared by Landlord.
As used in this Lease the words tenant and landlord include the plural as well
as the singular. Words used in the neuter gender include the masculine and
feminine gender.

13.15. RIGHTS OF MORTGAGEE.

This Lease shall be subordinate to any existing mortgage currently encumbering
the Premises and to any and all advances made or to be made thereunder and any
extensions, renewals or modifications thereof, unless the holder of such
mortgage elects to cause the Lease to be superior to such mortgage. This Lease
shall be subordinate to any future mortgages or ground leases from time to time
encumbering the Premises, executed or delivered subsequent to the date of this
Lease and to any and all advances made or to be made thereunder and any
extensions, renewals or modifications thereof (unless the holder or ground
lessor elects to cause the Lease to be superior to such mortgage or ground
lease), provided such mortgagee or ground lessor enters into an agreement (upon
such terms as are customarily required by institutional lenders) recognizing
Tenant under this Lease and providing that in the event of a foreclosure Tenant
shall remain undisturbed under this Lease if Tenant is not in default (after
applicable notice and grace periods) under any of the terms and conditions of
this Lease (a "nondisturbance agreement"). Tenant agrees to execute such
instruments of subordination in confirmation of the foregoing agreement as such
holder may request. Landlord agrees to use reasonable efforts to obtain a
nondisturbance agreement from the holder of the existing mortgage on the
Premises.

13.16. STATUS REPORT.

Recognizing that Landlord may find it necessary to establish to third parties,
such as accountants, banks, mortgagees, purchasers or the like, the then current
status of performance hereunder, Tenant, on the request of Landlord made from
time to time, will within 10 days of such request furnish to Landlord, or the
holder of any mortgage encumbering the Premises, or such other party, as the
case may be, a statement in form provided by Landlord, of the status of any
matter pertaining to this Lease, to the best of Tenant's knowledge after due
inquiry, including, without limitation:

                                       34

<PAGE>

     (a)  That the Lease is unmodified and in full force and effect or, if there
          has been any modification, that the same is in full force and effect,
          as modified and stating any such modification;

     (b)  Whether or not there are any existing setoffs or defenses against the
          enforcement of any of the terms, agreements, covenants and conditions
          of this Lease and any modifications thereof on the part of Tenant to
          be performed or complied with, and if so, specifying the same;

     (c)  The date to which Fixed Rent and all additional rent and other charges
          have been paid; and

     (d)  Any other matters reasonably requested by the Landlord or such other
          party.

Any statement furnished pursuant to this Section may be relied upon by Landlord,
any mortgagee or ground lessee, any purchaser, or by any other third party
interested in the status of this Lease or the Premises. Landlord agrees to
execute similar estoppel certificates regarding the Lease, to its knowledge,
upon the request of Tenant from time to time.

13.17. TENANT'S FINANCIAL CONDITION.

Tenant warrants and represents that all financial statements furnished to
Landlord or Landlord's representatives in connection with this Lease are true
and correct and properly reflect the same without material adverse change, as of
the date hereof. Upon Landlord's request, which may be made no more often than
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).

13.18. ADDITIONAL REMEDIES OF LANDLORD; SURVIVAL.

     13.18.1. 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, Landlord shall have
the same rights and remedies as Landlord has hereunder for the failure of Tenant
to pay the Fixed Rent.

     13.18.2. 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 (after notice to
Tenant and the expiration of any applicable cure period), 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).

13.19. WAIVER OF COUNTERCLAIMS.

If Landlord commences any summary proceeding for nonpayment of Fixed Rent,
additional rent or any other payments due hereunder, Tenant hereby waives the
right to interpose any non-compulsory counterclaim of whatever nature or
description in any such proceeding; provided, however, that Tenant

                                       35

<PAGE>

shall have the right to bring a separate action against Landlord to the extent
otherwise allowed under this Lease as long as Tenant does not attempt to have
such action joined or otherwise consolidated with Landlord's summary proceeding.

13.20. CONSENTS.

Except as otherwise specifically provided in this Lease, any consent or approval
to be given by Landlord under this Lease may be withheld or denied at Landlord's
sole and absolute discretion. Whenever in this Lease the consent or approval of
Landlord is required, and it is specifically provided that such consent or
approval is not to be unreasonably withheld, delayed or conditioned, but
nevertheless Landlord shall refuse or delay or condition such consent or
approval, Tenant shall not be entitled to make any claim, and Tenant hereby
waives any claim, for money damages (nor shall Tenant claim any money damages by
any setoff, counterclaim or defense) based upon any claim or assertion by Tenant
that Landlord unreasonably withheld or delayed or conditioned its consent or
approval; and Tenant's sole remedy in such circumstances shall be an action or
proceeding for specific performance, injunctive relief or declaratory judgment
and the prevailing party in any such proceeding shall be entitled to
reimbursement of its reasonably attorneys' fees and costs from the other.

13.21. HOLDING OVER.

If for any reason Tenant holds over or occupies the Premises beyond the Term,
Tenant shall have no more rights than a tenant by sufferance (or, at Landlord's
sole option, such holding over shall constitute a tenancy from month to month,
terminable by either party upon 30 days prior written notice to the other); and,
in any case, Tenant shall be liable for payment of rent during such period in an
amount equal to two times the rent (including Fixed Rent and all additional
rent) payable hereunder during the final year of the Term prior to such holding
over, for any month, or portion thereof, that Tenant so holds over or occupies
the Premises, with such tenancy otherwise on the same terms and conditions as
set forth in the Lease, as far as applicable. In addition, if Tenant holds over
beyond any such thirty (30) day written notice, Tenant shall save Landlord, its
agents and employees harmless and will exonerate, defend and indemnify Landlord,
its agents and employees from and against any and all damages which Landlord may
suffer on account of such hold over. Nothing in this Section shall be construed
to permit such holding over, or to limit Landlord's other rights and remedies on
account thereof.

13.22. NON-SUBROGATION.

Landlord and Tenant mutually agree that, with respect to any hazard which is
covered by insurance then being carried by them (or insurance that is required
to be carried hereunder), respectively, the one carrying (or required to carry)
such insurance and suffering such loss releases the other of and from any and
all claims with respect to such loss, to the extent of such coverage; and they
further mutually agree that their respective insurance companies shall have no
right of subrogation against the other on account thereof. Such waiver shall be
included in the policy, or such other party shall be named as an additional
insured in such policy, and the other party shall reimburse the party paying
such premium the amount of such extra premium. Each such policy which shall so
name a party hereto as an additional insured shall contain the agreement of the
insurer that the policy will not be canceled without at least 30 days notice to
both insureds and that the act or omission of on insured shall not invalidate

attached hereto as Exhibit C. During the Term hereof, and any extensions
thereof, and for 60 days after the expiration of the Term, or for so long

option, from implementing security measures for the Building or any part
thereof, in which event Tenant shall participate in such security measures and
the cost thereof shall be included within the definition of Operating Expenses,
and to the maximum extent permissible by law, Landlord shall have no liability
to Tenant and its agents, employees, contractors and invitees arising out of

easements, rights and dedications that Landlord deems necessary or desirable,
and to cause the recordation of parcel maps and restrictions, so long as such
easements, rights, dedications, maps and restrictions do not unreasonably
interfere with the use of the Premises by Tenant. Tenant shall sign any of the
aforementioned documents within ten (10) days after Landlord's request and
Tenant's failure to do so shall constitute a material default by Tenant. The
obstruction of Tenant's view, air, or light by any structure erected in the
vicinity of the Property, whether by Landlord or third parties, shall in no way
affect this Lease or impose any liability upon Landlord.

13.29. CHANGES TO PROPERTY.

and to consent to changes in the Office Park (hereinafter referred to

and exterior, the common areas and elements thereof, elevators, escalators,
restrooms, HVAC, electrical systems, communication systems, fire protection and
detection systems, plumbing systems, security systems, parking control systems,

connection with the Changes, Landlord may, among other things, erect scaffolding
or other necessary structures at the Property, limit or eliminate access to
portions of the Property, including portions of the common areas, or perform
work in the Building, which work may create noise, dust or leave debris in the
Building. Tenant hereby agrees that such Changes and Landlord's actions in
connection with such Changes shall in no way constitute a constructive eviction
of Tenant or entitle Tenant to any abatement of rent. Although Landlord shall
use commercially reasonable efforts to minimize any material interference of
Tenant's use or occupancy of or access to the Premises, Landlord shall have no
responsibility or for any reason be liable to Tenant for any direct or indirect
injury to or interference with Tenant's business arising from the Changes, nor
shall Tenant be entitled to any compensation or damages from Landlord for any
inconvenience or annoyance occasioned by such Changes or Landlord's actions in
connection with such Changes.

representations to Tenant concerning the condition or use by Tenant of the
Premises or the Property or concerning any other matter addressed by this Lease.

This Lease may be modified in writing only, signed by the parties in interest at
the time of the modification.

13.32. COVENANTS.

are independent and not dependent and Tenant hereby waives the benefit of any
statute to the contrary. All provisions of this Lease to be observed or
performed by Tenant are both covenants and conditions.

13.33. AUCTIONS.

Tenant shall not conduct, nor permit (with respect to the Premises only) to be
conducted, either voluntarily or involuntarily, any auction upon the Premises or
the Property. The holding of any auction on the Premises or Common Areas in
violation of this Section 13.33 shall constitute a default hereunder.

13.34. MERGER.

The voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation thereof, or a termination by Landlord, shall not result in the
merger of Landlord's and Tenant's estates, and shall, at the option of Landlord,
terminate all or any existing subtenancies or may, at the option of Landlord,
operate as an assignment to Landlord of any or all of such subtenancies.

13.35. AUTHORITY.

If Tenant is a corporation, limited liability corporation, trust, or general or
limited partnership, Tenant represents and warrants that each individual
executing and delivering this Lease on behalf of said entity, that said entity

trust or partnership, Tenant shall deliver to Landlord upon request evidence of
such authority satisfactory to Landlord.

13.36. RELATIONSHIP OF PARTIES.

hereto or by any third party to create the relationship of principal and agent,
partnership, joint venturer or any association between Landlord and Tenant.

Property as Landlord in its sole discretion shall determine, and Tenant is not
relying on any representation that any specific tenant or number of tenants will
occupy the Property.

13.38. CONFIDENTIALITY.

Tenant acknowledges and agrees that the terms of this Lease are confidential.
Disclosure of the terms hereof could adversely affect the ability of Landlord to
negotiate other leases with respect to the Building and may impair Landlord's
relationship with other tenants of the Building. Tenant agrees that it and its
partners, officers, directors, employees, brokers, and attorneys, if any, shall
not disclose the terms and

                                       40

<PAGE>

conditions of this Lease to any other person or entity without the prior written
consent of Landlord which may be given or withheld by Landlord, in Landlord's
sole discretion, except as required for financial disclosures, securities
filings or to parties involved in transactions permitted under Section 5.3
above. It is understood and agreed that damages alone would be an inadequate
remedy for the breach of this provision by Tenant, and Landlord shall also have
the right to seek specific performance of this provision and to seek injunctive
relief to prevent its breach or continued breach.

13.39. OFAC CERTIFICATION AND INDEMNITY.

reasonable discretion, confirming Tenant's compliance with these provisions. No
assignment or subletting shall be effective unless and until the assignee or
subtenant thereunder delivers to Landlord written confirmation of such party's
compliance with the provisions of this subsection, in form and content
satisfactory to Landlord. If for any reason the representations and warranties
set forth in this subsection, or any certificate or other evidence of compliance
delivered to Landlord hereunder, is untrue in any respect when made or
delivered, or thereafter becomes untrue in any respect, then an event of default
hereunder shall be deemed to occur immediately, and there shall be no
opportunity to cure. Tenant shall indemnify, defend with counsel reasonably
acceptable to Landlord, and hold Landlord harmless from and against, any and all
liabilities, losses claims, damages, penalties, fines, and costs (including
attorneys' fees and costs) arising from or related to the breach of any of the
foregoing representations, warranties, and duties of Tenant. The provisions of
this subsection shall survive the expiration or earlier termination of this

     reserves the right to reasonably restrict and regulate the use of
     aforementioned public areas of the Building by Tenant, Tenant's agents,
     employees, servants, licensees and visitors and by persons making
     deliveries to Tenant.

3.   After the conclusion of Tenant's initial move into the Premises, other
     movement in or out of the Building of furniture or office equipment which
     requires the use of elevators or stairways or the movement through the main
     Building entrance shall be restricted to the after business hours
     designated by Landlord. All such movement shall be under the supervision of
     Landlord and performed in the manner agreed upon between Tenant and
     Landlord by pre-arrangement before performance. Such pre-arrangement
     initiated by Tenant will include the determination by Landlord and subject
     to Landlord's reasonable discretion, relating to the time, method, and
     routing of the items' movement, as well as reasonable limitations imposed
     by safety, appearance or other reasonable concerns which may include the
     prohibition of equipment or any other item from being brought into the
     Building, as well as the method of the items' movement through the
     Building. Tenant shall assume with its contractors, all risk as to damage
     caused by any such movement or property being moved or injury to persons or
     public engaged or not engaged in such movement, including equipment,
     property, and personnel of Landlord if damaged or injured as a result of
     Tenant or its contractor's negligent or willful acts in connection with

     engaged in, or any damage or loss to any of said property or persons

     arrangement, except relating to Landlord's or its agent's or contractor's
     negligence or misconduct.

4.   After the conclusion of Tenant move-in, all deliveries, inclusive of
     packages, office supplies, etc., must be made via the freight elevator

     and padded side guards, shall be used in any space, or in public halls of
     the building, either by Tenant or by jobbers or others in the delivery or
     receipt of merchandise.

     its agents or

                               Exhibit B (Page 1)

<PAGE>

     employees will not accept, sign for, or hold Tenant mail, packages, or
     deliveries.

8.   Tenant shall not make, or permit to be made, any unseemly or disturbing
     noises, odors, or vibrations to emanate from premises or otherwise
     unreasonably disturb or interfere with the occupancy of the Building
     whether by the use of any equipment, musical instrument, radio, television,
     talking machine, unmusical noise, whistling, singing, or in any other way.

9.   No additional locks, or security devices will be installed without prior
     notification and approval by Landlord. New locks or rekeying must be
     coordinated with Landlord and keyed on building master system. Upon move-in
     all doors with locksets will be keyed to building master system and Tenant
     will be given 2 keys by Landlord. Additional keys may be requested in
     advance and at an additional charge to Tenant. Upon termination of Lease,
     Tenant will return 2 keys to each lock, and further will disclose any
     previously approved and installed security devices including combination
     locks, punch codes to doors and vaults.

10.  After the initial move-in, for which the distribution of access cards will
     be provided at no cost to Tenant, Tenant agrees to pay an amount fixed by
     Landlord from time to time, for each building access card issued by
     Landlord to Tenant for access to Building during non-business hours. Such
     expense is presently $10.00 per card.

11.  Landlord specifically reserves the right to exclude from the Building
     during non-business hours, such as before 8:00 a.m. and after 6:00 p.m. on
     weekdays, on Saturdays and Sundays, and Building recognized Holidays, all
     persons not permitted entry by utilizing card access, telephone access
     system, or previous arrangement with the management office.

12.  Tenant shall be responsible for persons it authorizes to have access to the
     Building during non-business hours and shall be liable for and shall
     coordinate which persons should have access cards issued. Tenant shall keep
     access card records current and properly identified by employee name.

13.  Landlord will not permit entrance to Tenant's premises or offices by use of
     pass keys controlled by Landlord to any person at any time except

     by Landlord. It is recommended that Tenant inform Tenant employees of these
     lockout procedures.

     through Building management office. Tenants will not contract independently
     with employees and agents of Landlord without the coordination of the
     management office, nor shall Tenant request employees or agents of Landlord
     to receive or carry messages for or to any Tenant or other person.

15.  None of the entries, passages, doors, elevators, elevator doors, hallways,

     egress by Tenant, Tenant's agents, employees, or invitees.

16.  No boxes, crates, pallets, or other such materials shall be stored in
     building hallways or other common areas. When Tenant must dispose of
     crates, boxes, etc., it will be the responsibility of Tenant to dispose of
     same prior to, or after the hours of 8:00 a.m. and 6:00 p.m., so as to
     avoid having such debris visible or being moved in the Common Areas during
     normal business hours. If such items are desired to be removed as part of
     evening janitorial service, the expense of such will be borne by Tenant.
