                             W I T N E S S E T H:

        The parties hereto, for themselves, their heirs, distributees,
executors, administrators, legal representatives, trustees, successors and
assigns, hereby covenant as follows:

          Landlord hereby leases to Tenant, and Tenant hereby leases from
Landlord, those certain premises, as said premises may be adjusted from time to
time (the "Demised Premises") consisting of approximately 57,860 square feet of
Rentable Area on the ground, first and second floors at 10 Westport Road,
Wilton, Connecticut, which building is located on a portion of the land
described on Schedule A attached hereto (the "Land"), being Parcel 2 as
             ----------
indicated on the plot plan attached hereto as Schedule B (said building,
                                              ----------
together with all other buildings on the Land, being hereinafter collectively
referred to as the "Building"), together with the right, in common with others,
to use all areas of the Project (as hereinafter defined) that are made available
from time to time for common use by tenants of the Building. The Building
consists of three (3) separate but connected areas commonly referred to as
building "A", building "B" and building "C", together with the Hansen House. The
Land, the Building, any existing or future rooftop parking areas, surface
parking areas on the Land, and surface parking areas below any Building, and all
other improvements now or hereafter constructed on the Land, except improvements
which tenants may remove therefrom pursuant to the terms of their respective
leases, and together with certain easement areas and Complex Common Areas as set
forth in that certain Declaration of Easements, Covenants and Restrictions dated
June 23, 1998 and recorded in Volume 1107 at Page 133 of the Wilton Land Records
(the "REA"), are collectively referred to herein as the "Project." The Land,
together with Parcel 1, as shown on Schedule B ("Parcel 1") are together
                                    ----------            -
referred to herein as the "Complex". Parcel 1 shall not be part of the Project.
The Demised Premises are depicted on Schedule C attached hereto. Landlord
                                     ----------
represents that the Rentable Area of the Demised Premises and the Building have
been calculated substantially in accordance with the Building Owners and
Managers Association method of measurement (ANSI Z65.1-1996).


                                   ARTICLE 1

                                     RENT

        1.1      Tenant shall pay to Landlord annual net rent (the "Annual Net
Rent") as follows:

          (i)    Twenty-two Dollars and 00/100 ($22.00) multiplied by the total
number of square feet of Rentable Area in the Demised Premises per annum for the
period commencing on the Rent Commencement Date and ending on the last day of
the sixtieth (60th) full month after the Rent Commencement Date; and

          (ii)   Twenty-six Dollars and 00/100 ($26.00) multiplied by the total
number of square feet of Rentable Area in the Demised Premises per annum for the
sixty-first (61st) through one hundred twentieth (120th) full months after the
Rent Commencement Date; and

          (iii)  Twenty-nine Dollars and 00/100 ($29.00) multiplied by the total
number of square feet of Rentable Area in the Demised Premises per annum for the
one hundred twenty-first (121st) through one hundred forty-fourth (144th) full
months after the Rent Commencement Date.

                                       2
<PAGE>

        Tenant will pay the Annual Net Rent in lawful money of the United States
of America, in equal monthly installments in advance on the first day of each
calendar month during the Term, at the offices of Landlord as set forth in the
beginning of this Lease or such other place in the United States of America as
Landlord designates.  If the obligation to pay Annual Net Rent commences on any
day other than on the first day of a calendar month, then the Annual Net Rent
for the period from the date on which the obligation commences to the first day
of the calendar month shall be prorated on a per diem basis.

        The first month's installment of Annual Net Rent shall be paid by Tenant
upon the execution of this Lease and shall be credited by Landlord to the
payment of the Annual Net Rent that first becomes payable under this Lease.

        1.2    Tenant shall pay the Annual Net Rent and Additional Rent (as
defined in the immediately succeeding sentence), by good and sufficient check
(subject to collection) drawn on a local bank which is a member of the New York
Clearing House Association or of a successor to that Association. All sums of
any kind other than Annual Net Rent that are payable by Tenant under this Lease
are "Additional Rent," and shall be payable within fifteen (15) business days
following demand by Landlord, unless other payment dates are provided in this
Lease; such sums shall be Additional Rent solely for the purpose of providing to
Landlord the same remedies as are available to it in the event of default in the
payment of Annual Net Rent.

        1.3    If Tenant fails to pay when due any installment of Annual Net
Rent or any payment of Additional Rent, then Tenant shall pay interest thereon
at the Interest Rate (as defined in Article 22 hereof), from the date on which
that installment or payment becomes due to the date on which it is paid.

        1.4    If, due to a Law which (a) limits Landlord's right to collect
or receive all, or any part of, either or both of the Annual Net Rent and the
Additional Rent (together, the "Total Rents") or (b) requires that Landlord
refund any of the Total Rents that Landlord already has received (either of
which is referred to as a "Rent Restriction"), Landlord does not receive or
retain all amounts on account of Total Rents that, but for the Rent Restriction,
Landlord would have received or retained, then Tenant shall enter into such
agreements and take such other steps as Landlord requests to permit Landlord to
collect the maximum amount of the Total Rents that Landlord may be permitted to
collect from time to time during the continuance of the Rent Restriction (but
not in excess of the amounts provided for under this Lease). Upon the
termination of the Rent Restriction, (a) the Total Rents shall be payable in
full, and (b) Tenant shall pay to Landlord, to the maximum extent legally
permissible, an amount that is equal to the excess of (i) the Total Rents which
would have been paid but for the Rent Restriction, over (ii) the Total Rents
that were paid during the period that the Rent Restriction was in effect.

        1.5    Annual Net Rent, Additional Rent and all other sums payable
hereunder by Tenant shall be paid without notice or demand, and without setoff,
counterclaim, abatement, suspension, deduction or defense of any kind
whatsoever, except as may otherwise be expressly provided in this Lease. Annual
Net Rent shall be entirely "net" to Landlord, it being intended that Tenant
shall be required to pay, as Additional Rent, all costs and expenses of
operating the Demised Premises. Except as may otherwise be expressly provided in
this Lease, this Lease shall not terminate, nor shall Tenant be entitled to the
abatement of any rent hereunder or any reduction thereof, nor shall, except as
otherwise set forth herein, the obligations of Tenant under this Lease be
otherwise affected for any reason whatever, it being the intention of the
parties hereto that the obligations of Tenant hereunder shall be separate and
independent covenants and agreements, that the rent and all other sums payable
by Tenant hereunder shall continue to be payable in all events, and the
obligations of Tenant hereunder shall continue unaffected, unless the
requirement to pay or perform the same shall have been terminated, abated or
reduced pursuant to an express provision of this Lease.

                                   ARTICLE 2

                                   TERM AND
                   COMPLETION AND OCCUPANCY OF THE PREMISES

         2.1    Landlord shall, at its cost, have the work described on Schedule
H attached hereto ("Landlord's Work") performed.  Items 2 and 5 of Landlord's
Work shall be substantially completed on or before July 1, 2001.  Item 1 of
Landlord's Work shall be commenced when LDC (defined below) vacates the Demised
Premises and Landlord shall use commercially reasonable, diligent efforts to
substantially complete item 1 on or before the Rent Commencement Date and, to
the extent that item 1 is not substantially completed on or before the Rent
Commencement Date, the completion of such work shall be done in a manner, and at
time, such that Tenant's use of the rooftop parking during Tenant's occupancy of
the Demised Premises is not materially impaired.  Items 3 and 4 of Landlord's
Work shall be commenced upon substantial completion of the Tenant Improvements
and completed as soon as reasonably possible thereafter, subject to the time of
year and weather delays.  Such work shall be done in a manner, and at times,
such that Tenant's use of the parking areas during Tenant's occupancy of the
Demised Premises is not materially impaired and if any such material impairment
occurs, Landlord shall provide alternate temporary parking for Tenant at the
Complex.  Landlord's Work shall be performed in a good and workmanlike manner
and in compliance with all Laws.

         2.2    Tenant shall, at Tenant's cost and expense (including
application of the Tenant Improvement Allowance specified in the workletter
attached hereto as Schedule D (the "Workletter")), perform or cause to be
                   ----------
performed the Tenant Improvements (as defined in the Workletter) in order to
prepare the Demised Premises for its initial occupancy.

         2.3    The term of this Lease ("Term") shall commence on the date
(herein called the "Commencement Date") that Landlord delivers vacant possession
of the Demised Premises to Tenant for Tenant to commence the Tenant
Improvements. The Term shall end on the last day (the "Expiration Date") of the
month in which occurs the day preceding the twelfth (12th) anniversary of the
Rent Commencement Date (as that term is hereinafter defined), unless sooner
terminated or extended pursuant hereto. Immediately after the Rent Commencement
Date, Landlord and Tenant shall execute and acknowledge an agreement in the form
attached hereto as Schedule E setting forth the Commencement Date and the Rent
                   ----------
Commencement Date of this Lease, provided that any failure of the parties to
execute such written agreement shall not affect the validity of the Commencement
Date or the Rent Commencement Date. Tenant acknowledges that the Commencement
Date is anticipated to be on or around July 1, 2001.

         2.4    Tenant's obligation to pay any Annual Net Rent and Additional
Rent shall commence on the date (herein called the "Rent Commencement Date")
which shall be the earlier to occur of (i) the date on which Tenant first
conducts its business from any portion of the Demised Premises, or (ii) three
(3) months after the Commencement Date.  Notwithstanding the foregoing, Tenant
may, at its option, by written notice to Landlord, delay the Rent Commencement
Date until the date which is four (4) months after the Commencement Date, in
which event Annual Net Rent shall, for the first twelve (12) full months
following the Rent Commencement Date only, increase by $8,148.62 per month.

        2.5     Except as otherwise provided in this Lease, the taking of
occupancy of the whole or any part of the Demised Premises for the commencement
of the Tenant Improvements by Tenant shall be conclusive evidence, as against
Tenant, that Tenant accepts possession of the same and that the Demised Premises
so occupied were in good and satisfactory condition at the time such occupancy
was so taken and that the Demised Premises or such portion thereof were
substantially as shown on Schedule C. The Commencement Date shall occur no later
                          ----------
than the taking of such occupancy.

                                       4
<PAGE>

        2.6    Landlord shall have the right to utilize the Land for purposes of
excavation work and shall have the right to authorize the use of, and grant
temporary licenses and easements over, the Land to owners of adjacent property
or governmental authorities for excavation purposes, provided that (i) Landlord
provides to Tenant with reasonable prior notice of any such work, authorizations
or grants that would materially adversely affect Tenant's business in the
Demised Premises (except in an emergency), (ii) Landlord shall use commercially
reasonable efforts to minimize any interference with Tenant's business as a
result thereof, and (iii) in no event shall Tenant be unable to reasonably
conduct its business in the Demised Premises as a result thereof.

        2.7    Tenant acknowledges that the Demised Premises are currently
occupied by Louis Dreyfus Corporation ("LDC"), and that Landlord cannot deliver
vacant possession of the Demised Premises to Tenant until LDC vacates the
Demised Premises.  Landlord represents that LDC has entered into, or will enter
into, a lease with 20 Westport Holdings, L.L.C., the owner of Parcel 1, pursuant
to which LDC will lease space in a building being built by 20 Westport Holdings,
L.L.C. on Parcel 1 (the "Parcel 1 Building"), and thereby vacate the Demised
Premises.  Landlord agrees to deliver vacant possession of the Demised Premises
to Tenant immediately after LDC vacates the Demised Premises, and Landlord
agrees to give Tenant thirty (30) days notice of the date on which Landlord
expects that the Commencement Date will occur.  In the event that Landlord does
not deliver vacant possession of the Demised Premises to Tenant on or before
August 1, 2001 (which date shall be extended by Force Majeure), then Tenant, as
its sole remedy as a result thereof, shall receive a credit against Annual Net
Rent that first becomes due hereunder, in an amount equal to one (1) day of
Annual Net Rent for each such day of delay, which credit shall increase to two
(2) days of Annual Net Rent for each such day of delay beyond November 1, 2001
(which date shall be extended by Force Majeure), provided that Tenant's credits
against Annual Net Rent under this Section 2.7 shall cease to accrue on the
Final Date (defined below).  In the event that Landlord does not deliver vacant
possession of the Demised Premises to Tenant on or before January 1, 2002 (which
date (the "Final Date") shall be extended by Force Majeure), then Tenant, as its
sole remedy as a result thereof, may terminate this Lease by written notice to
Landlord within thirty (30) days after the Final Date.  For purposes of this
Section 2.7 only, Force Majeure shall have the meaning ascribed to it in Article
33 hereof, but shall also include the inability to deliver vacant possession of
the Demised Premises to Tenant, if the reason why Landlord cannot deliver vacant
possession to Tenant is that LDC cannot occupy its space in the Parcel 1
Building because of a Force Majeure Event (using the definition in Article 33
hereof as applied to 20 Westport Holdings, L.L.C.) that delays the completion of
the Parcel 1 Building, which definition shall, for purposes hereof, include any
delays that are caused by the default by any construction manager or contractors
of the Parcel 1 Building under their construction contracts relating to the
Parcel 1 Building; failure of any such construction manager or contractor to
perform because of any lack of or delayed payment shall not constitute a Force
Majeure Event.


                                   ARTICLE 3

                              ADJUSTMENT OF RENT

        3.1    For the purposes of this Article 3, the following definitions
shall apply:

               (a)  The term "Tenant's Share" shall mean 29.73% (57,860 divided
by 194,615), which is the percentage calculated by dividing the total Rentable
Area of the Demised Premises by the total Rentable Area of the Building.

               (b)  The term "Taxes" shall mean the amount of (i) all real
estate taxes, assessments, sewer and water rents, governmental levies, municipal
taxes, county taxes and any other governmental charge, general or special,
ordinary or extraordinary, unforeseen as well as foreseen, of any kind or nature
whatsoever, which is or may be assessed, levied or imposed upon all or any part
of the Land, the Building, the Project and the sidewalks, or streets in front of
or adjacent thereto, including any payment in lieu of taxes or any tax, excise
or fee measured by or payable with respect to any rent, any of which

                                       5
<PAGE>

is levied against or payable by Landlord with respect to the Land, the Building,
the Project or any combination thereof, under the laws of the United States, the
State of Connecticut, or any political subdivision thereof, and (ii) all
expenses incurred by Landlord in contesting any of the foregoing set forth in
clause (i) of this sentence or the assessed valuation of all or any part of the
Land, the Building and the Project. Landlord shall contest Taxes or the
valuation of the Land, the Building or the Project, if Tenant establishes, to
Landlord's reasonable satisfaction, that a contest is warranted for a first
class building owner in Fairfield County. If, due to a change in the method of
taxation or in the taxing authority, a new or additional real estate tax, or a
franchise, income, transit, profit or other tax or governmental imposition,
however designated, is levied against or payable by Landlord with respect to the
Land, the Building, the Project or any combination thereof, in addition to, or
in substitution in whole or in part for any tax which would constitute "Taxes,"
or in lieu of additional Taxes, that tax or imposition shall be included within
the term "Taxes." Notwithstanding the foregoing, Taxes shall exclude any and all
income, estate, inheritance, death, succession, franchise, partnership,
corporate or capital stock taxes of Landlord.

               (c)  The term "Tax Year" shall mean (i) each period of twelve
months, commencing on the first day of July of each such period within which
occurs any part of the Term, or (ii) such other period of twelve months which
occurs during the Term as is adopted as the fiscal year for real estate tax
purposes of the Town of Wilton, Connecticut.

               (d)  The term "Expenses" shall mean the total of all of the costs
and expenses (and taxes thereon, if any) paid or incurred by Landlord during any
Operating Year with respect to the operation and maintenance of the Project and
the services provided to the tenants of the Building computed on an accrual
basis including the costs and expenses with respect to the following:
electricity, steam, gas and any other fuel or utilities; water rates and sewer

replacement thereof, expenses imposed on Landlord pursuant to Law or to any
collective bargaining agreement with respect to such employees; worker's

attendants, clerks, messengers, and other receiving room personnel, services,
systems and supplies; directory; repairs, replacements and improvements which
are necessary or appropriate for the continued operation of the Building as a
first-class office building and Project (even if the same are classified as
capital expenditures under generally accepted accounting principles) including
repairs, replacements and improvements to the electrical, mechanical, plumbing
and HVAC systems; management fees for the management of the Project, whether or
not an outside managing agent is employed by Landlord, provided that management
fees shall not be included in Expenses in an amount which is in excess of the
then prevailing rates for management fees in the lower Fairfield County Area for
first-class office buildings similar to the Building; all costs of operation,
maintenance and security of any automated teller machine located at the Project;
costs and expenses that relate to portions of the Complex other than the Land,
as allocated to the Project in accordance with reasonable formulae established
by Landlord, including, without limitation, an equitable portion of the costs of
operation and maintenance for any parking on Parcel 1 (including, without
limitation, any structured parking facility or surface parking areas on parcel
1) during any period of time that Landlord is

                                       6
<PAGE>

providing any parking, in such parking on Parcel 1, for Tenant and/or any other
tenants of the Building; and any costs and expenses required to be paid by
Landlord pursuant to the terms of the REA. If the Building is less than 100%
occupied during any part of the Operating Year, Expenses shall mean the amount
obtained by adjusting actual Expenses for such Operating Year to a 100%
occupancy level, such adjustments to be made by adding to the actual expenses
during such Operating Year such additional amounts as would have been incurred
if the Building had been 100% occupied.

          Notwithstanding anything in Section 3.1(d) to the contrary, if
Landlord makes any capital improvements which are required by any Law that
becomes effective after the Rent Commencement Date or under generally applied
real estate practice in the operation of first-class office buildings in the
lower Fairfield County Area or that Landlord makes which are intended to result
in savings or reductions in expenses or to benefit or increase the safety and
security of Building tenants and invitees, then the costs for those capital
improvements shall be amortized and charged as an expense over the useful life
of each improvement (as reasonably determined by Landlord (but not to exceed a
period of ten years)), and shall be included in Expenses for the Operating Year
(as defined in Section 3.1(e)) in which the costs are incurred and subsequent
Operating Years, on a straight-line basis, with interest at the Prime Rate.

          If Landlord leases any item of capital equipment which, if it were
purchased would be amortized and included in Expenses, then the rentals and
other costs paid pursuant to the leasing shall be included in Expenses for the
Operating Years in which they are incurred.

          Notwithstanding anything in Section 3.1(d) to the contrary, the
following costs and expenses shall not be included in Expenses or, in the case
of (iv), shall be deducted from Expenses:

                    (i)     if electricity furnished to the Demised Premises is
measured by meters and paid by Tenant directly to the utility supplier then the
cost of electricity to other leasable portions of the Building shall be excluded
from Expenses;

                    (ii)    leasing commissions;

                    (iii)   salaries for Landlord's employees above the grade of

reason of fire or other casualty or condemnation to the extent to which Landlord
receives compensation through proceeds of insurance or a condemnation award;

                    (vi)    payments of principal and interest on any mortgages
upon either or both of the Land and the Building;

                    (vii)   payments of ground rent pursuant to any ground lease
covering either or both of the Land and the Building;

                    (xiii)    legal or other fees, leasing commission,
advertising expenses, promotional expenses and other costs incurred in leasing
or attempting to lease any portion of the Building or in any litigation with any
tenant;

                    (xiv)     any insurance premium to the extent that Landlord
is specifically entitled to be reimbursed therefor by Tenant pursuant to this
Lease (other than pursuant to this Section 3.1(d)) or by any other tenant or
other occupant of the Building pursuant to its lease (other than pursuant to an
operating expense clause contained therein);

                    (xv)      the cost of any items for which Landlord is
entitled to be reimbursed by any tenant other than pursuant to an operating
expenses clause;

                    (xvi)     the cost of any alterations, additions, changes,
replacements, improvements and repairs and other items which are made in order
to prepare space for occupancy by a new tenant;

                    (xvii)    the cost of electricity furnished to the Demised
Premises or any other leased or leasable space in the Building;

                    (xviii)   (A) ground rents and mortgage debt service, (B)
reserves for anticipated future expenses, bad debt loss, or rent loss, (C)
interest and penalties incurred as a result of Landlord's delinquent payment of
any obligation of Landlord, (D) costs associated with the operation of the
business of the entity which constitutes Landlord, which costs are not directly
related to the operation, management, maintenance and repair of the Project
including, by way of example, and without limitation, the formation of the
entity, internal accounting and legal matters, preparation of tax returns and
financial statements, costs of instituting or defending any lawsuits (including,
without limitation, costs and legal fees incurred in enforcing leases against
tenants, including Tenant), costs of selling, syndicating, financing, mortgaging
or hypothecating any of Landlord's interest in the Building, and costs of any
disputes between Landlord and its employees, (E) costs of removing or otherwise
remediating any Hazardous Materials that are at the Land or Building as a result

benefits and expenses or persons engaged in the maintenance or management of the
Building who also provide services for other properties under common control or
management, based on the portion that the number of hours such persons provide
services other than for the Building bears to the total number of hours such
persons provide service to all subject properties, and (B) the excess of the
costs of services performed by Landlord, its subsidiaries and affiliates, to the
Building over competitive costs for such services rendered by non-affiliated
persons or entities of similar skill and experience,

                                       8
<PAGE>

                    (xx)      costs to originally construct (as distinguished
from operation and maintenance) the Building or any expansion thereof;

                    (xxi)     (A) costs resulting from the gross negligence of
Landlord, or its agents, contractors, employees or of any tenants of the
Building, (B) costs of services or other benefits supplied to other tenants in
the Building but not provided to Tenant, (C) costs resulting from violations by
Landlord or other tenants of any lease, including this Lease, (D) costs arising
from Landlord's charitable or political contributions, (E) compensation paid to
clerks, attendants, or other persons in commercial concessions operated by
Landlord, (F) costs of acquiring valuable works of art located within or outside
of the Building.

          If during all or part of any Operating Year, Landlord does not furnish
any item of work or service (which if it were furnished would be included in
calculating Expenses) to portions of the Project, because construction of the
Building or the Project is not completed, or such portions are not occupied or
leased, or because such item of work or service is not required or desired by
the tenant of such portion, or such tenant is itself obtaining and providing
such item of work or service, or for other reasons, then, for the purpose of
computing Tenants Expense Payment (as defined in Section 3.2) and
notwithstanding that Landlord did not incur the cost, the amount of the cost for
such item for such period which would reasonably have been incurred during such
period by Landlord if it had furnished such item shall be included in Expenses.

                    (e)       The term "Operating Year" shall mean the calendar
year in which the Rent Commencement Date occurs and each subsequent calendar
year within which any portion of the Term falls.

                    (f)       The term "Additional Rent Statement" shall mean a
statement furnished by Landlord to Tenant setting forth the amount payable by
Tenant in respect of Taxes for a specified Tax Year or in respect of Expenses
for an Operating Year (as the case may be) pursuant to this Article 3.

          3.2       Tenant shall pay to Landlord on account of each Operating
Year an amount equal to Tenant's Share of the Expenses for such Operating Year
("Tenant's Expense Payment").

          3.3       (a)  Landlord shall furnish to Tenant for each Operating
Year an Additional Rent Statement (subject to revision as provided in this
Section 3.3) setting forth Landlord's estimate of Tenant's Expense Payment for
such Operating Year (the "Estimated Expense Statement"). Tenant shall pay to
Landlord on the first day of each month during such Operating Year an amount
equal to one-twelfth of Tenant's Expense Payment that, is shown on the Estimated
Expense Statement for such Operating Year. Notwithstanding the foregoing, if the
Rent Commencement Date is other than the first day of an Operating Year and/or
the date of the Expiration or other termination of this Lease for reasons other
than Tenant's default (both, a "Term Completion") is a day other than the last
day of an Operating Year, then Tenant's Expense Payment (as shown on the
Estimated Expense Statement) shall be proportionately pro-rated for such
Operating Year(s) based on the number of days during such Operating Year(s)
which fall on and after the Rent Commencement Date and otherwise within the Term
of this Lease. If Landlord furnishes the Estimated Expense Statement for an
Operating Year after the commencement of the Operating Year, then until the
first day of the month following the month in which the Estimated Expense
Statement is furnished to Tenant, Tenant shall pay to Landlord on the first day
of each month an amount equal to the monthly sum payable by Tenant to Landlord
under this Section 3.3 for the last month of the preceding Operating Year.

                    (b)  Landlord may at any time and from time to time (but not
more than three times in any Operating Year) furnish to Tenant an Estimated
Expense Statement setting forth Landlord's reasonably revised estimate of
Tenant's Expense Payment for a particular Operating Year. After the end of each
Operating Year, Landlord shall submit to

                                       9
<PAGE>

Tenant an annual Additional Rent Statement setting forth the Expenses in
reasonable detail for the preceding Operating Year and the balance of Tenant's
Expense Payment, if any, due to Landlord from Tenant for such Operating Year.
Landlord shall endeavor to provide each Additional Rent Statement within one
hundred twenty (120) days after the end of each Operating Year. Within thirty
(30) days following Tenant's receipt of a revised Estimated Expense Statement
for an Operating Year or of the annual Additional Rent Statement for the
preceding Operating Year, Tenant shall pay to Landlord an amount equal to the
amount of any underpayment of Tenant's Expense Payment with respect to such
Operating Year and, in the event of an overpayment, Landlord shall credit the
amount of Tenant's overpayment against the next accruing subsequent charges due
under this Article 3.

          3.4       Tenant shall pay to Landlord on account of any Tax Year all
or any portion which occurs during the Term of this Lease an amount equal to
Tenant's Share of the Taxes for such Tax Year ("Tenant's Tax Payment").

          3.5       (a)  Landlord shall furnish to Tenant for each Tax Year an
Additional Rent Statement that sets forth the amount of Taxes for that Tax Year.
Tenant's Tax Payment for each Tax Year shall be due and payable in two semi-
annual installments in advance, on the first day of each June and December, in
amounts based upon the Additional Rent Statement furnished with respect to that
Tax Year. If the Additional Rent Statement is furnished to Tenant after the
commencement of the Tax Year in respect of which that Additional Rent Statement
is furnished, Tenant shall, within thirty (30) days after receipt of that
Additional Rent Statement, pay to Landlord an amount that is equal to the amount
of Tenant's Tax Payment with respect to that Tax Year which would have been paid
during that Tax Year before the end of the 30-day period if the Additional Rent
Statement for that Tax Year had been furnished by the Landlord to Tenant before
the commencement of that Tax Year.  Landlord, at its option, may require Tenant
to make payments on account of Tenant's Tax Payment on a monthly basis, in which
event the procedures set forth in Section 3.3 hereof shall apply thereto, or on
such quarterly or other basis as Landlord shall require from time to time.

                    (b)  At any time during or after a Tax Year in respect of
which Landlord has furnished an Additional Rent Statement, Landlord may furnish
to Tenant one or more corrected Additional Rent Statements if the Taxes actually
due were incorrectly reflected in the original or any prior Additional Rent
Statement. If Landlord does furnish such a corrected Additional Rent Statement,
then if the amount of the payments that were made by Tenant on account of
Tenant's Tax Payment for that Tax Year is (i) less than the amount of the
payments that the Tenant should have made based upon the corrected Additional
Rent Statement, then within thirty (30) days after receipt by Tenant of the
corrected Additional Rent Statement Tenant will pay to Landlord the amount of
the underpayment; or (ii) more than the amount of payments that Tenant should
have made based upon the corrected Additional Rent Statement, then Landlord
shall credit the overpayment against the next accruing subsequent charges due
under this Article 3.

          3.6       (a)  The benefit of any discount for early payment or
prepayment of Taxes shall accrue solely to Landlord's benefit and such discount
shall not be subtracted from Taxes.

                    (b)  If the real estate fiscal year of the Town of Wilton is
changed during the Term, then, (i) the term "Tax Year" shall be deemed to mean
that real estate tax year as so changed, and (ii) Tenant's Tax Payments shall be
computed and paid separately in respect of the Tax Year before the change and
the Tax Year after the change on the basis of the number of days in each.

                    (c)  If Landlord receives a refund or reduction of Taxes in
respect of any Tax Year, then Landlord shall credit an amount that is equal to
Tenant's Share of the amount of the refund or reduction that applies to any
portion of the Term, less costs and expenses incurred by Landlord for the
purpose of receiving such refund, against the next accruing subsequent charges
due under this Article 3, provided that in no event shall Tenant be double
charged (under this

                                       10
<PAGE>

Section 3.6(c) and under Section 3.1(d) hereof) for costs and expenses incurred
to receive a refund of or reduction in Taxes.

          3.7       On or prior to its due date, Tenant shall directly pay to
the appropriate taxing authorities the amount of all occupancy taxes and rent
taxes now or in the future in effect that are levied on or measured by Annual
Net Rent or Additional Rent. If, in the future, such taxes are included within
the term Taxes, then Tenant shall not be obligated to make payments to the
taxing authorities as described in this Section 3.7.

          3.8       If the Rent Commencement Date is other than the first day of
a Tax Year or the Term Completion is a day other than the last day of a Tax
Year, then Taxes shall be proportionately reduced for such Tax Year(s) by
multiplying Taxes by (i) a fraction, the numerator of which is the number of
days beginning with the Rent Commencement Date in such Tax Year, and the
denominator of which is 365 and/or (ii) a fraction, the numerator of which is
the number of days prior to and including the date of Term Completion in such
Tax Year and the denominator of which is 365.

          3.9       If, prior to the Expiration Date, Landlord is unable to give
Tenant appropriate credits for the entire refund or reduction and return of
overpayment sums to which Tenant is entitled pursuant to Section 3.3(b), 3.5(b),
3.6(c) or 3.13, then Landlord shall refund the balance to Tenant within thirty
days following the Expiration Date.

          3.10      Except as otherwise specifically provided, in no event shall
the Annual Net Rent be reduced by operation of this Article 3. The rights and
obligations of Landlord and Tenant under the provisions of this Article 3 with
respect to any Additional Rent Statement shall survive the Term Completion and
shall apply to any Additional Rent Statement furnished to Tenant after the Term
Completion.

          3.11      Landlord's failure to render an Additional Rent Statement
with respect to any Tax Year or Operating Year shall not prejudice Landlord's
right to thereafter render an Additional Rent Statement and receive payments
with respect thereto or with respect to any subsequent Tax Year or Operating
Year, or prejudice Tenant's right to contest the amount of Additional Rent due
for the Tax Year or Operating Year in question.

          3.12      Each Additional Rent Statement shall be conclusive and
binding upon Tenant unless within sixty (60) days after receipt of that
Additional Rent Statement Tenant notifies Landlord that Tenant disputes the
correctness of such Additional Rent Statement, specifying the particular
respects in which the Additional Rent Statement is claimed to be incorrect. Any
dispute relating to any Additional Rent Statement that is not resolved within
one hundred twenty (120) days after the rendering of such Additional Rent
Statement may be submitted to arbitration by either party pursuant to Article 35
pending the determination of the dispute, Tenant shall pay Additional Rent when
due in accordance with the Additional Rent Statement that Tenant is disputing,
without prejudice to Tenant's right to recover any portion of the Additional
Rent that is determined to not be due to Landlord.

          3.13      Tenant may, at its sole cost and expense and upon reasonable
written notice given within sixty (60) days after receipt of an Additional Rent
Statement, elect to have an accountant selected by Tenant and reasonably
acceptable to Landlord, examine Landlord's books and records relating to
Expenses as are relevant to the Operating Year in question.  If it is ultimately
determined that an Additional Rent Statement overstated Expenses for the
Operating Year in question by more than 4%, then Landlord shall reimburse Tenant
for all reasonable third party costs incurred by Tenant in examining Landlord's
books and records relating to Expenses for that Operating Year Landlord shall
credit the amount of any overpayment by Tenant against the next accruing charges
due under this Article 3.

                             SERVICE AND UTILITIES

        4.1      (a)  Landlord shall supply, subject to its ability to obtain
the same from the public utility furnishing electricity to the Building,
electrical power to the Building including the Demised Premises (through
equipment and facilities installed by Tenant as part of the Tenant Improvements)
and the common areas.  Exclusive of HVAC, Landlord shall provide six (6) watts
per usable square feet of space in the Demised Premises, on a connected load
basis, for light and power.  The obligations of the Landlord hereunder shall be
subject to any rules and regulations of the authority providing electricity to
Landlord.  Tenant shall, at Tenant's sole cost and expense, and in accordance
with Schedule D hereof, install as part of the Tenant Improvements, submeters in
     ----------
the Demised Premises to measure Tenant's electrical consumption for light and
power and air conditioning therein and Landlord shall furnish electricity to the
Demised Premises on a submetered basis.  The cost of Tenant's electrical
consumption in the Demised Premises shall be paid by Tenant to Landlord, as
Additional Rent hereunder and shall be charged to Tenant by applying the then
current electricity supplier's rate as charged to Landlord ("Landlord's Rate")
to the consumption determined by the submeter readings and adding thereto an
amount equal to  one half (1/2%) percent of the amount which is the result of
such application, for Landlord's administrative costs in supplying electric to
the Demised Premises on a submetered basis.  Bills for such amounts shall be
rendered to Tenant monthly and shall be payable by Tenant within twenty (20)
Business Days after the date so rendered.  The obligations of Landlord hereunder
shall be subject to any rules and regulations of the authority providing
electricity to Landlord.  For the purpose of this Section 4.1(b) the rate to be
paid by Tenant shall include any taxes, energy charges, demand charges, fuel
adjustment charges, rate adjustment charges, or other charges imposed by the
utility company or any governmental body in connection therewith. If any tax
shall be imposed upon Landlord's receipts from the sale or resale of electrical
energy to Tenant by any federal, state, city or local authority, the pro rata
share of such tax allocable to the electrical energy service received by Tenant
shall be passed on to, included in the bill of and paid by Tenant.

                 (b)     Tenant shall pay directly to Landlord as the same
becomes due all charges for the consumption of electricity used in the Demised
Premises during the performance of the Tenant Improvements, based upon an
electric usage survey conducted on behalf of Landlord.

                 (c)     Tenant will not (i) use electrical energy that exceeds
the capacity of the then existing risers, feeders and other electrical equipment
of the Building, or (ii) make or perform or permit the making or performing of
any alterations to wiring, installations or other electrical facilities in or
serving the Demised Premises without the consent of the Landlord in each
instance. Any additional risers, feeders, or other equipment proper or necessary
to supply Tenant's electrical requirements, upon written request of Tenant, will
be installed by Landlord, at Tenant's cost, if those risers, feeders or other
equipment are necessary to supply those requirements and will not cause
permanent damage or injury to the Building or the Demised Premises, or cause or
create a dangerous or hazardous condition or entail unreasonable alterations,
material repairs or expense or materially interfere with or disturb other
tenants or occupants.

                 (d)     Landlord shall not in any way be liable or responsible
to Tenant for any loss or damage or expense which Tenant sustains or incurs if
either the quantity or character of electric service is changed or is no longer
available or suitable for Tenant's requirements.

                 (e)     Landlord reserves the right to discontinue furnishing
electricity to Tenant in the Demised Premises on not less than ninety (90) days'
notice to Tenant. If Landlord exercises such right to discontinue, or is
compelled to discontinue furnishing electricity to Tenant, this Lease shall
continue in full force and effect and shall be unaffected thereby, except only
that from and after the effective date of such discontinuance, Landlord shall
not be obligated to furnish electricity to Tenant. If Landlord so discontinues
furnishing electricity to Tenant, Tenant shall arrange to obtain electricity
directly from the public utility or other company servicing the Building. Such
electricity may be furnished to Tenant by means of the then

                                       12
<PAGE>

existing electrical facilities serving the Demised Premises to the extent that
the same are available, suitable and safe for such purposes. All meters and all
additional panel boards, feeders, risers, wiring and other conductors and
equipment which may be required to obtain electricity, of substantially the same
quantity, quality and character, shall be installed by Landlord, at Tenant's
sole cost and expense. Landlord shall not voluntarily discontinue furnishing
electricity to Tenant unless and until Tenant is able to receive electricity
directly from the public utility or other company servicing the Building.

        4.2      Landlord shall provide to the Demised Premises:

                 (a)     Necessary elevator facilities during Business Hours and
at least one passenger elevator subject to call at all other times.

                 (b)     Heat and air-conditioning through the Building systems
when reasonably required during Business Hours. The HVAC system is or shall be
designed to maintain (a) 75 (+1) degrees Fahrenheit dry bulb when outdoor
conditions are 91 degrees Fahrenheit dry bulb and 76 degrees Fahrenheit wet bulb
and (b) 70 degrees Fahrenheit dry bulb when outdoor conditions are 0 degrees
Fahrenheit dry bulb. Total air distribution is or shall be designed to provide
not less than 0.9 CFM per usable square foot and will be controlled by a
Building management system. Building air conditioning supply systems are or
shall be designed with minimum 75% efficiency air filters. Tenant shall cause
all operable windows, if any, in the Demised Premises to be kept closed (except
for cleaning purposes), shall keep entirely unobstructed all heat and air-
conditioning vents, intakes, outlets and grilles at all times and shall comply
with and observe all regulations and requirements prescribed by Landlord for the
proper functioning of the HVAC systems. The HVAC for the Building is designed
based upon (i) electrical heat dissipation load of four (4) watts per usable
square foot, and (ii) occupancy rate of 1 person per 150 usable square feet and
shades fully closed to limit exposure to direct solar radiation. Tenant shall
pay Landlord's reasonable charges for heat and air conditioning during periods
other than Business Hours, as Additional Rent, within thirty (30) days after
receiving bills from Landlord therefor. In the event that Tenant shall require
air conditioning or heating during periods other than Business Hours, then
Tenant shall give Landlord reasonable advance notice of such requirement.
"Reasonable advance notice" for purposes of this paragraph shall mean
notification before 12:00 noon of the Business Day on which the described
services are required (other than Saturdays) and before 12:00 noon of the last
Business Day preceding the non-Business Day, or any Saturday, on which the
described services are required. Landlord's current non-Business Hours charges
are $100.00 per hour for air-conditioning and $25.00 per hour for heat.

                 (c)     Standard cleaning and janitorial services on Business
Days in accordance with the cleaning specifications annexed hereto as Schedule
                                                                      --------
F. If Tenant requires cleaning and janitorial services in excess of those
-
standard services, then Tenant shall so notify Landlord. If Landlord elects to
provide those services, then Tenant shall pay Landlord's charges therefor within
thirty (30) days after receipt of Landlord's invoice therefor.

                 (d)     Hot and cold water for lavatory, drinking and office
cleaning purposes. If Tenant requires, uses or consumes water in quantities that
are materially in excess of standard office usage (as reasonably determined by
Landlord), then Landlord may install a meter or meters or other means to measure
Tenant's water consumption, and Tenant will reimburse Landlord for the cost of
installation and maintenance of the meter or meters or the cost of Landlord's
other means of measuring the water consumption by Tenant, in each case within
thirty (30) days after receipt of Landlord's invoice therefor. Tenant shall
reimburse Landlord for the cost of all water consumed, as so measured, plus 1/2%
thereof, for Landlord's administrative costs in connection therewith, together
with any taxes, sewer rents or other charges which are imposed by any Law based
on the quantity of water used by Tenant.

        4.3      Landlord may, without any liability whatsoever or abatement of
Total Rents, interrupt, curtail, suspend or stop the heating, air-conditioning,
elevator, plumbing, electric and other systems or the use of any Building
facilities

                                       13
<PAGE>

when necessary by reason of accident, strike or emergency or for repairs,
alterations, replacements or improvements, or because of inability to secure a
supply of fuel, gas, steam, water, electricity, labor or supplies, or because of
any similar or dissimilar cause beyond the reasonable control of Landlord.
Landlord shall, at reasonable times and after reasonable prior notice (which may
be oral), except in an emergency, have free and unrestricted access to any and
all mechanical, plumbing and electrical installations of Landlord in the Demised
Premises, and Tenant shall not erect or place any partition or other obstruction
which reasonably interferes with Landlord's free access to those installations
or with the moving of Landlord's equipment to and from the enclosures containing
those installations. Tenant, its agents, employees and contractors shall not
enter said enclosures or adjust, touch or in any way tamper with those
installations. Notwithstanding the foregoing, if Tenant's business in the
Demised Premises is materially affected, as a result of an interruption of
services or utilities, (a) for more than three (3) consecutive business days, if
the interruption is caused by Landlord's gross negligence or willful misconduct,
or (b) if not the result of Landlord's gross negligence or willful misconduct,
if Landlord does not commence to cure the problem (to the extent within
Landlord's control) within ten (10) days after the interruption, thereafter
diligently pursue the cure, or (to the extent within Landlord's control), cure
the problem within thirty (30) days after the interruption, then in the case of
(a) or (b), Annual Net Rent shall, as Tenant's sole remedy, equitably abate, in
proportion to the interference with Tenant's business, subsequent to the
expiration of the applicable period, until the interruption ends.

        4.4      Landlord shall not be obligated to provide building security to
the Building, except for a card access system for the perimeter of the Building,
and at least one (1) security guard on a 24 hour per day, 7 days per week basis.
Tenant shall be responsible for obtaining, from the Building management office
or the card access system provider (as determined by Landlord), security cards
for all of Tenant's visitors.  Landlord shall have no liability to Tenant, nor
shall Tenant's obligations under this Lease be in any way affected in the event
that such security measures are not effective, unless such failure is caused by
Landlord's gross negligence or willful misconduct.

        4.5      To the extent permitted by the owner of the Parcel 1 Building,
Landlord shall, upon request from Tenant, cooperate with Tenant to permit Tenant
and its employees to use the fitness center in the Parcel 1 Building. Tenant
acknowledges that there may be a charge for such usage.

        4.6      Landlord will not furnish any services, except as provided in
this Lease.


                                   ARTICLE 5

                                   CAFETERIA

        5.1      For the purposes of this Article 5, the following definitions
shall apply:

                 (a)     "Break-Even Basis" shall mean the point at which, from
time to time, the sum of all Cafeteria Expenses, including, without limitation,
the Cafeteria Caterer's fee, equals all income derived in connection with the
operation and maintenance of the Cafeteria business.

                 (b)     "Cafeteria Caterer" shall mean any independent
contractor which operates the Cafeteria (as hereinafter defined) pursuant to
separate contracts with Landlord or any other person or entity or pursuant to a
single contract in accordance with terms of this Article 5.

                 (c)     "Cafeteria Expenses" shall mean all expenses in
connection with the operation, maintenance and repair of the Cafeteria business,
including, without limitation, the cost of all foodstuffs, beverages and other

                                       14
<PAGE>

goods to be sold or used for preparing or packaging the goods to be sold in the
Cafeteria; the Cafeteria Caterer's fee; the salaries, wages, fringe benefits and
all other compensation and other benefits of all Cafeteria employees; the cost
of any dishes, glassware or utensils, amortization of the cost of new
refrigeration and other kitchen equipment and accessories; the cost of
maintaining or repairing all Cafeteria-related equipment; the costs of cleaning
the dining areas and the areas in front of food service counters; heat,
electricity, lighting; other utilities; and the costs of goods and services to
be provided by the Cafeteria Caterer.

        5.2      In the cafeteria located in the Hansen House (the "Cafeteria"),
Landlord shall provide (or may contract with a Cafeteria Caterer to provide)
food services to the employees of Tenant and other occupants of the Building.
Landlord reserves the right, at any time from time to time in its sole and
absolute discretion, to change the Cafeteria Caterer, provided that each
Cafeteria Caterer shall operate the Cafeteria as a first class cafeteria.

        5.3      The maximum hours the Cafeteria will be open for Tenant's use
on Business Days shall be 7:30 A.M. - 9:30 A.M and 11:00 A.M. - 2:00 P.M. The
level of goods and services which Landlord or the Cafeteria Caterer shall
provide during any given Business Day will vary, but Landlord shall use all
reasonable efforts to cause the Cafeteria to have goods and services that are
consistent with a first class cafeteria. Upon reasonable advance notice, the
Cafeteria Caterer will provide catering services to Tenant within the Demised
Premises. Any profits generated by the Cafeteria Caterer from such catering
activities shall be included in the calculation of the Break-Even operation of
the Cafeteria.

        5.4      Tenant acknowledges and agrees to and for the benefit of
Landlord that (a) the efficiency and the extent of, and the food selection at,
the Cafeteria are directly related to the number of users and, accordingly, when
Tenant and other tenants or occupants at the Building vacate leased space at the
Building, the nature and the extent of the services provided at the Cafeteria
may be changed by Landlord, including, without limitation, changes to the food
menu and menu pricing; and (b) Landlord shall not be subject to any liability,
nor shall Tenant be entitled to any compensation or diminution or abatement of
rent, by reason of Landlord's exercise of any rights reserved with respect to
the modification of the Cafeteria services provided pursuant hereto or if
Landlord elects to cease operating the Cafeteria pursuant to Section 5.6 below.

        5.5      The Cafeteria is currently operating on a subsidy basis,
whereby each tenant in the Building pays Landlord, on a monthly basis, its share
(as equitably determined by Landlord) of the amount by which the Cafeteria does
not operate on a Break-Even Basis (the "Subsidy Basis"). Tenant shall use the
Cafeteria on a Subsidy Basis unless Tenant notifies Landlord, in writing, that
it wishes to have Landlord cause the Cafeteria Caterer to raise menu pricing for
Tenant and its employees and guests to a Break-Even Basis. Tenant may change
from the Subsidy Basis to a Break-Even Basis or vice-versa from time to time on
not less than three (3) months prior notice to Landlord. In addition, Landlord
shall have the right, from time to time, to have the Cafeteria as a whole
operate on a Break-Even Basis or a Subsidy Basis.

        5.6      Notwithstanding the foregoing, if the Cafeteria is not
operating on a Break-Even Basis and any shortfall is not being subsidized by
Tenant and other tenants in the Building, Landlord may cease operating the
Cafeteria upon sixty (60) days' notice to Tenant unless Tenant shall elect, in
its sole discretion, with or without the cooperation of other tenants in the
Building, within said sixty (60) day period, to subsidize the Cafeteria so that
it does operate on a Break-Even Basis as a whole.

        5.7      If Landlord elects to cease operating this Cafeteria as
provided in Section 5.6 hereof, Tenant may operate the Cafeteria itself, through
a cafeteria caterer that is reasonably acceptable to Landlord. Any such
cafeteria caterer retained by Tenant shall satisfy such insurance, security and
other requirements as Landlord shall reasonably impose.

        5.8      Landlord shall consult with Tenant on a regular basis regarding
the operation of the Cafeteria, and

                                       15
<PAGE>

shall use commercially reasonable efforts to address any complaints that Tenant
has regarding the quality or variety of the food served in the Cafeteria.

        5.9      Tenant may obtain catering in the Demised Premises from a
caterer selected by Tenant, but only if the Cafeteria Caterer will not provide
such catering, and subject to Landlord's approval of the caterer and such
caterer satisfying such insurance, security and other requirements as Landlord
shall reasonably impose.

injury to person or property, or for loss or damage to any automobile or its
contents, resulting from theft, collision, vandalism or any other cause
whatsoever and, except to the extent caused by Landlord's negligence or willful
misconduct, Tenant hereby agrees to indemnify, hold harmless and defend Landlord
from and against any and all causes, claims, suits, damages and expenses
(including reasonable attorneys' fees) arising from the use of the parking
spaces at the Project by Tenant or anyone claiming by, through or under Tenant's
privileges granted hereunder;

                 (c)     Subject to the terms of this Article 6, Tenant agrees

first-serve basis; (ii) the right to park cars, on a non-designated, first-come,
first-serve, basis, on the roof of the Building; and (iii) the right to park

Allocation shall include not less than sixty-eight (68) Designated Spaces and
parking for not less than 95 cars on the roof of the Building.

of this Lease, at any time and from time to time Landlord shall have the
following rights:


                         (i)     to require Tenant to reserve or otherwise
identify its parking spaces or to require Tenant's employees to identify their
vehicles in a manner reasonably determined by Landlord. Landlord may require
that Tenant's employees identify their vehicles with stickers provided by
Landlord; and

                                       16

                         (ii)      to tow unidentified or unmarked visitor or

                 (f)     Tenant acknowledges and agrees that Tenant shall have
the following responsibilities and obligations throughout the Term of this
Lease:

                         (i)       to comply in all respects with the parking

                         (ii)      to insure that at all times Tenant's
employees and visitors do not use more parking spaces than Tenant's Parking
Allocation, so as to avoid use of parking spaces allocated to other tenants and
their visitors at the Project or the Complex, and in connection therewith, if
Landlord, in its reasonable opinion, determines that Tenant has not allowed
enough of Tenant's designated spaces to visitor parking, then Landlord may
require Tenant to reallocate Tenant's designated spaces between its employees
and its visitors to increase the portion of Tenant's designated spaces that is
allocated to visitor parking; and

                         (iii)     to comply in all respects with the reasonable
rules and regulations with regard to the parking system established by Landlord
or the parking operator (and, with respect to any of Tenant's parking on Parcel
1, any reasonable rules and regulations established by the owner or parking
operator thereof), as the same may be modified from time to time.


                                   ARTICLE 7

                                QUIET ENJOYMENT

                                   ARTICLE 8

                                 SUBORDINATION

        8.1      This Lease is and shall be subject and subordinate to all
ground or underlying leases which now or hereafter affect either or both of the
Land and the Building, to all mortgages which now or hereafter affect such
leases or either or both of the Land and the Building, and to all renewals,
modifications, replacements and extensions of any thereof. The provisions of
this Section 8.1 shall be self-operative and no further instrument of
subordination shall be required. In confirmation of that subordination, Tenant
shall promptly execute and deliver at its own cost and expense any instrument,
in recordable form reasonably satisfactory to Tenant, if required, that
Landlord, the lessor of the ground or underlying lease or the holder of any such
mortgage or any of their respective successors in interest request to evidence
the subordination. In consideration of, and as an express condition precedent
to, Tenant's agreement to permit its interest pursuant to this Lease to be
subject and subordinate to any ground or underlying leases or the lien of any
mortgage, Landlord shall deliver to Tenant a subordination, non-disturbance and
attornment agreement executed and delivered by each of Landlord's mortgagees and

                                       17
<PAGE>

ground lessors for the benefit of Tenant and in reasonable form, and Tenant
agrees to execute and deliver any such subordination, non-disturbance and
attornment agreement. If Landlord elects not to request such subordination, non-
disturbance and attornment agreement or fails to obtain such subordination, non-
disturbance and attornment agreement, then this Lease shall not be subject and
subordinate to such mortgage or lease.

        8.2      In the event of a termination of any ground or underlying
lease, or if the interest of Landlord under this Lease is transferred by reason
of, or is assigned in lieu of, foreclosure or other proceedings for enforcement
of any mortgage, or if the holder of any mortgage acquires a lease in
substitution for its mortgage, then Tenant will, if requested in writing by the
lessor under such ground or underlying lease or such mortgagee or purchaser,
assignee or lessee, as the case may be (each of which is referred to as
"Purchaser" for purposes of this Section 8.2) (i) attorn to the Purchaser and
will perform for the Purchaser's benefit all the provisions of this Lease to be
performed by Tenant with the same force and effect as if the Purchaser were the
landlord originally named in this Lease, or (ii) if the Purchaser alternatively
requests, enter into a new lease with the Purchaser as landlord, for the
remaining Term on the same terms and conditions. The foregoing provisions of
clause (i) of this Section 8.2 shall inure to the benefit of the Purchaser,
shall be self-operative if the Purchaser elects to make such request, and no
further instrument shall be required to give effect to those provisions. Upon
demand of the Purchaser, Tenant will execute, from time to time, instruments in
confirmation of the foregoing provisions of this Section 8.2 and 8.3 below,
reasonably satisfactory to Tenant , acknowledging such attornment and setting
forth the terms and conditions of its tenancy. Upon Tenant's attornment to a
successor landlord, this Lease shall continue in full force and effect as a
direct lease between the successor in interest to Landlord and Tenant upon,
subject to Section 8.3 below, all of the terms, conditions and covenants as are
set forth in this Lease.

        8.3      Anything contained in this Article 8 to the contrary
notwithstanding, under no circumstances shall the Purchaser, whether or not it
shall have succeeded to the interests of Landlord under this Lease, be:

                 (a)     liable for any act, omission or default of any prior
landlord, except to the extent that the condition resulting from such act,
omission or default continues after the date the Purchaser acquires title to or
a leasehold interest in the Land and Building; or

                 (b)     subject to any offsets, claims or defenses which Tenant
might have against any prior landlord, except to the extent that the condition
giving rise to such offset, claim or defense continues after the date the
Purchaser acquires title to, or a leasehold interest in the Land and Building;
or

                 (c)     bound by any rent or additional rent which Tenant might
have paid to any prior landlord for more than one month in advance or for more
than three months in advance where such rent payments are payable at intervals
of more than one month, except to the extent expressly provided for in this
Lease; or

                 (d)     provided that Tenant has received written notice of
such Purchaser at such time, bound by any modification, amendment or abridgement
of the Lease which adversely affects the Purchaser, or any cancellation or
surrender of this Lease, made without the Purchaser's prior approval.

        8.4      If, in connection with the financing of the land and/or the
Building, the holder of any mortgage or any potential mortgagee requests
reasonable modifications be made in this Lease as a condition to making the
financing or approving this Lease, then Tenant shall not unreasonably withhold,
delay or defer making such modifications, if those modifications do not increase
the Annual Net Rent or Additional Rent or otherwise increase Tenant's
obligations under this Lease, or diminish Tenant's rights under this Lease,
other than in a de minimis manner.

usable square feet in the Demised Premises at any one time.  Tenant shall be

any unlawful purposes or in any unlawful manner, or (b) suffer or permit the
Demised Premises or any part thereof to be used in any manner or anything to be

expense, shall procure and thereafter maintain such license or permit and supply
a copy thereof to Landlord. Tenant, at its expense, shall at all times comply
with the terms and conditions of each such license or permit.

conflict with any exclusive use granted by Landlord to any other tenant in the
Building.

conditions:

                 (a)     Tenant shall submit to Landlord and Landlord shall have
approved (i) reasonably detailed plans and specifications for the entire
Alterations (the "Alteration Plans"), provided that Landlord's approval shall
not be required for purely cosmetic Alterations that are not visible from the

Contractors so approval are reputable, competent, or will satisfactorily perform
their obligations to Tenant.

                 (g)     All of the Work shall be done in a good and workmanlike
manner.

                 (h)     Notwithstanding that Landlord has approved a
Contractor, Tenant shall not employ any Contractor unless the Contractor has
agreed in writing that it will employ only such labor as will not result in
jurisdictional disputes or strikes or result in disharmony with other workers
employed in the Building.

                 (i)     Tenant shall pay to each of the Contractors, as the
Work progresses, the entire cost of supplying the materials and performing the
work, pursuant to the contract between the parties.

                 (j)     All Alterations shall be made in compliance with all
Laws and with the rules, orders, regulations and requirements of the New York
Board of Fire Underwriters or any similar body.

                                       20
<PAGE>

                 (k)     All of the Work shall be done at such times and in such
manner as will not unreasonably interfere with or disturb other tenants or
occupants of the Building.

                 (l)     Landlord and its representatives shall have the right,
but shall have no obligation, upon reasonable prior notice to Tenant (which may
be oral), to inspect the progress of the Work and the completed Alterations at
all reasonable times, and Tenant shall permit Landlord to make such inspections;
but any such inspection shall not obligate Landlord to notify Tenant of any
failure by Tenant to comply with the requirements of this Lease (although
Landlord shall endeavor to do so) or constitute an approval or waiver by
Landlord of any condition or of any failure by Tenant to perform its obligations
under this Lease.

                 (m)     Tenant will pay to Landlord (i) an amount that is equal
to three percent (3%) of the cost of the Alterations (less the cost of business
equipment and furniture, fixtures and equipment and less any costs attributable
solely to above building standard finishes, in excess of what building standard
finishes would have cost) to compensate Landlord for Landlord's indirect costs,
field supervision and coordination in connection with the Work, and (ii) all
direct costs incurred by Landlord related to the Work including , supplemental
cleaning and refuse removal.

                 (n)     Before commencing the Alterations, Tenant shall furnish
to Landlord certificates evidencing the existence of:

                         (i)       Worker's compensation insurance covering all
persons employed for the Work with statutorily required limits.

                         (ii)      Comprehensive general liability and property
damage insurance (which shall be in addition to insurance required to be
provided under Article 13 of this Lease) naming Landlord, its designees and
Tenant as additional insured, as their interests may appear, with coverage in
such amounts as Landlord may require (which requirement shall be consistent with
business practice in the real estate business in the lower Fairfield County
Area).

                         (iii)     Any other insurance which Landlord reasonably
requests.

        Before commencing the Alterations, Tenant shall furnish evidence
satisfactory to Landlord that Tenant has notified all Contractors that Landlord
will not be liable for any labor or materials furnished or to be furnished to
Tenant upon credit, and that the Contractor may not impose any mechanic's or
other lien for any labor or materials on any interest or estate of Landlord in
and to the Demised Premises or the Building.

        10.2     Within 30 days after any mechanic's lien is filed against the
Demised Premises or the Building for work claimed to have been done or materials
claimed to have been furnished to Tenant, Tenant will discharge such lien, at
Tenant's expense, by payment or filing of a bond required by law or otherwise.
Tenant shall provide satisfactory proof of such discharge to Landlord within
that 30-day period; and if Tenant fails to do so then Landlord may, but shall
not be obligated to, discharge the mechanic's lien by bond or payment, or
otherwise, and the cost of the discharge will be paid by Tenant to Landlord upon
receipt of Landlord's invoice therefor.

        10.3     If any notice of violation is placed against the Building and
that violation arises out of the Alterations, then the violation shall be cured
by Tenant immediately, and if Tenant fails to do so, then Landlord may, but
shall not be obligated to, cure the violation by whatever reasonable action
Landlord deems to be necessary, including the removal of all or any part of the
Alterations, and the cost of the action taken by Landlord shall be paid by
Tenant to Landlord upon receipt

                                       21
<PAGE>

of Landlord's invoice therefor.

          10.4      Except as Landlord and Tenant may otherwise agree in writing
at the time the Alterations are made, all Alterations made and installed by
Landlord at Landlord's expense shall be Landlord's property and shall remain
upon and be surrendered with the Demised Premises as part thereof at the
Expiration Date or upon termination of this Lease due to Tenant's default (both,
a "Termination").

          10.5      All Alterations made and installed or paid for by Tenant,
which are of a permanent nature and which cannot be removed without damage to
the Demised Premises or the Building, shall become and be the property of
Landlord and shall remain upon and be surrendered with the Demised Premises at
the Termination, except to the extent that Landlord, at the time that it
approves any Alterations, notifies Tenant that Tenant must remove any of the
Alterations upon a Termination, in which event, Tenant shall, at Tenant's own
expense, remove the Alterations in accordance with Landlord's request and
restore the Demised Premises to its original condition, ordinary wear and tear
and casualty excepted. Landlord agrees, however, that it will not require Tenant
to remove anything that would be done as part of a standard office build-out.
For purposes hereof, a standard office build-out shall consist of the following:

                    (a)      Drywall interior partitions

                    (b)      Entrance, exit and interior doors and hardware

                    (c)      Suspension ceiling

                    (d)      Fluorescent light fixtures and exit lights

                    (e)      Carpet and/or vinyl tile

                    (f)      Electrical wiring and equipment for normal office
                             usage

                    (g)      Fire alarm wiring and equipment and smoke detectors

                    (h)      Sprinkler piping and heads

                    (i)      Distribution of heat, ventilation and air
                             conditioning (but not supplementary HVAC)

                    (j)      Window treatments.

          10.6      Subject to Landlord's rights, if any, under Article 20
hereof, all trade fixtures, movable office furniture and equipment and any other
movable property that has been furnished or paid for by Tenant ("Tenant's
Personal Property") shall remain Tenant's property; and Tenant shall remove
Tenant's Personal Property before any Termination.

          10.7      If any of the Alterations or Tenant's Personal Property
which Tenant has the right or obligation to remove or which Landlord has
requested Tenant to remove, as provided in Sections 10.5 and 10.6 ("Removable
Property") are not removed within the time periods required by Sections 10.5 and
10.6, then the Removable Property shall be deemed abandoned. Landlord, at its
election, may either retain some or all of the Removable Property or remove some
or all of the Removable Property and dispose of the Removable Property without
accountability to Tenant and Tenant shall pay to Landlord upon receipt of
Landlord's invoice with appropriate back up therefor, all reasonable costs
incurred by Landlord in removing,

                                       22
<PAGE>

storing or disposing of the Removable Property and, in the case of Removable
Property which cannot be removed without damage to the Demised Premises or the
Building, the costs of restoring the Demised Premises or the Building. Tenant's
obligations under Sections 10.5 and 10.6 and this Section 10.7 shall survive a
Termination. The foregoing provisions of this Section 10.7 shall be without
prejudice to any election by Landlord that Tenant's failure to remove Removable
Property constitutes a holding over by Tenant pursuant to Section 27.2.

          10.8      Tenant shall keep records, including the Alteration Plans,
copies of contracts, invoices, evidences of payment and all other records
normally maintained in the real estate business relating to all Alterations and
Work and of the cost thereof, and shall provide any and all of those records to
Landlord at any time and from time to time at Landlord's written request, for
any purpose.

          10.9      Tenant shall not place a load upon any floor of the Demised
Premises exceeding a live load of 100 pounds per square foot of floor space
(80+20).

          10.10     No property of any kind shall be brought upon or kept by
Tenant in the Demised Premises other than as an incident to the reasonable use
of the Demised Premises for the purposes permitted by this Lease. Tenant shall
not move any safe, heavy equipment, freight, bulky matter or bulky fixtures
("Heavy Objects") into or out of the Building or change the location thereof in
the Demised Premises without Landlord's consent, which consent shall not be
unreasonably withheld, conditioned or delayed, as long as there will be no
material adverse affect on the Building or its operation (including traffic
flow) as a result thereof. If the moving of any Heavy Objects requires special
handling with rigging equipment, Tenant will employ only persons holding a
Master Riggers license to do the moving, and all work in connection therewith
shall comply with applicable Law.

          10.11     Tenant will install proper vibration eliminators on all
business machines and mechanical equipment which Tenant is responsible for
maintaining in such manner as will prevent any perceptible vibration.

          10.12     Tenant and Tenant's contractors will abide by Landlord's
rules and regulations governing Alterations to be performed in the Building,
which rules and regulations shall be uniformly applied throughout the Building.

          10.13     Upon completion of any Alterations, Tenant shall furnish
Landlord, with three (3) copies each of architectural and mechanical As-Built
drawings.

          10.14     In the event of any conflict between the provisions of this
Article 10 and Schedule D attached hereto, the provisions of Schedule D shall
govern with respect to the Tenant Improvements.



                                  ARTICLE 11

                                    REPAIRS

          11.1      (a) Tenant shall take good care of the Demised Premises and
the fixtures, appurtenances and equipment therein (collectively, "Fixtures"),
and any supplemental HVAC system installed by Tenant, and at its sole cost and
expense make all repairs thereto as and when needed to preserve them in good
working order and condition. All damage or injury to the Demised Premises and to
its Fixtures which is caused by or results from (i) moving Tenant's property in
or out of the Building, or (ii) the installation or removal of Tenant's
furniture, Fixtures or other property, or (iii) the carelessness, omission,
neglect, negligence, or improper conduct of Tenant or its employees,
contractors, agents, licensees or invitees, shall

                                       23
<PAGE>

be repaired, restored or replaced promptly by Tenant at its expense to the
reasonable satisfaction of Landlord. Such repair, restoration and replacement
shall be in quality and class equal to the original work or installation. If
Tenant fails to promptly make any such repair, restoration or replacement, then
the repair, restoration and replacement may be made by Landlord at the expense
of Tenant (and Landlord shall provide appropriate back up therefor).

                    (b)  Neither the exterior walls of the Building nor the
windows and the exterior areas created by the Building set backs are part of the
Demised Premises and Landlord reserves all rights to those walls, windows and
setbacks, including the right to enter and temporarily store window washing and
other supplies and equipment on the setback areas.

          11.2      Landlord, as part of Expenses to the extent provided for in
Section 3.1 (d) hereof, will perform all necessary repairs, replacements and
maintenance of (i) the Building systems and Building structural components,
including the foundation, floor slabs, roof, walls and utility lines outside of
the stub locations within the Demised Premises, (ii) all utility lines, pipes,
ducts, conduits and the like in the Building which run through the Demised
Premises and service all parts of the Building other than the Demised Premises
and all work required to keep the Demised Premises watertight (for example, the
roof, gutters and downspouts), and (iii) all parking areas at the Building.
Landlord will, in general, operate and maintain the Building as a first class
building in Fairfield County.  Landlord will commence repairs within a
reasonable period of time after it is notified of the necessity of such repairs
and shall diligently prosecute such repairs to completion. Notwithstanding the
above, Landlord shall not be obligated to pay, as part of Expenses, and Tenant
shall pay to Landlord the entire cost of all maintenance, service and repairs
performed by Landlord with respect to the Building systems that are required to
repair damage or injury due to the carelessness, omission, neglect, negligence
or improper conduct of Tenant, its employees, contractors, agents, licensees or
invitees.

          11.3      There shall be no allowance to Tenant for diminution of
rental value and no liability on the part of the Landlord by reason of
inconvenience, annoyance, interruption or injury to business arising from the
making or failing to make by Landlord of any repairs, alterations, additions or
improvements in or to any portion of the Building or the Demised Premises or in
or to fixtures, appurtenances or equipment thereof, provided that in making any
repairs, replacement and maintenance, Landlord shall exercise all reasonable
efforts to minimize inconvenience to Tenant in connection therewith and no
action taken by Landlord under this provision shall permanently impede access
to, reduce the size or otherwise diminish the utility of the Demised Premises in
any material respect, including any services provided thereto.


                                  ARTICLE 12

                              REQUIREMENTS OF LAW

          12.1      Tenant, at Tenant's expense, shall comply with all Laws
which impose any violations, order or duty upon Landlord or Tenant with respect
to the Demised Premises, or the use or occupation thereof.

          12.2      Notwithstanding the provisions of Section 12.1, Tenant, at
its expense, in its name (and whenever necessary in Landlord's name) may
contest, in any manner permitted by law (including appeals to a Court, or
governmental department or authority having jurisdiction in the matter), the
validity or the enforcement of any Law with which Tenant is required to comply
pursuant to this Lease, and may defer compliance therewith (collectively, the
"Contest") if:

                    (a)  The Contest does not subject Landlord to the payment of
any fine or penalty or to criminal prosecution or subject either or both of the
Land and Building to lien or sale;

                    (b)  The Contest does not result in a violation of any
mortgage or of any ground or underlying

                                       24
<PAGE>

lease;

                    (c)  Before commencing the Contest, Tenant has delivered to
Landlord a surety bond issued by a surety company of recognized responsibility,
or other assurance reasonably satisfactory to Landlord, indemnifying and
protecting Landlord against any liability, loss or injury by reason of the
Contest; and

                    (d)  Tenant shall promptly and diligently prosecute the
Contest and keep Landlord advised at all times with reasonable promptness as to
the status of the Contest.

Landlord, without liability to it and at Tenant's expense (including the payment
of Landlord's attorneys, fees), shall cooperate with Tenant and execute any
documents or pleadings required for the Contest, if Landlord is reasonably
satisfied that the facts set forth in any such documents or pleadings are true
and complete and not misleading.

          12.3      Landlord shall contest any law that Landlord is required to
comply with respect to the Building, if Tenant establishes, to Landlord's
reasonable satisfaction, that a contest is warranted for a first class building
owner in Fairfield County.

          12.4      Except to the extent that compliance is Tenant's obligation
under Section 12.1 hereof, Landlord shall comply with all Laws applicable to the
Building and the Project, including Environmental Laws (as defined below). The
costs thereof shall be included in Expenses to the extent provided for in
Section 3.1(d) hereof. Landlord represents that, to the best of Landlord's
knowledge, the Building (other than the Demised Premises) is currently in
compliance with all Laws, other than the Americans with Disabilities Act
("ADA"), provided that Landlord represents that, to the best of Landlord's
knowledge, the bathrooms within the Demised Premises will, on the Rent
Commencement Date, be in substantial compliance with ADA, as reasonably
determined by Landlord.

          12.5      (a)  Landlord represents that, to the best of Landlord's
knowledge after reasonable inquiry, there has been no Release of any Hazardous
Materials (as hereinafter defined) at or onto the Land or Building and that no
Hazardous Materials, including but not limited to asbestos, asbestos-containing
materials, lead paint or polychlorinated bi-phenyls, are present at the Land or
Building in a condition that, under applicable Environmental Laws, require
remediation.

                    (b)  Landlord represents that, to the best of Landlord's
knowledge after reasonable inquiry, the Land and Building are free from
contamination by hazardous materials and do not constitute an "establishment",
as that term is defined in the Connecticut Transfer Act, Conn. Gen. Stat.
Section 22a-134 et seq., as amended (the "Act").

                    (c)  For purposes of this Lease, these following terms shall
have the respective meanings:

                         (i)  "Environmental Laws" means any and all federal,
State of Connecticut, local or municipal written and published laws, rules,

approvals or registrations required to be issued to Landlord by any governmental

                                  ARTICLE 13

                  INSURANCE, LOSS, INDEMNIFICATION, LIABILITY

          13.1      Tenant shall not do or permit to be done any act or thing
upon the Demised Premises which will invalidate Landlord's insurance policies
covering the Building or Fixtures and property therein, or which would increase
the rate of fire insurance applicable to the Building to an amount higher than
it otherwise would be; and Tenant shall neither do nor permit to be done any act
or thing upon the Demised Premises which unreasonably subjects Landlord to any
liability or responsibility for injury to any person or persons or to property
by reason of any business or operation being carried on within the Demised
Premises. Tenant, at its expense, shall comply with all rules, orders,
regulations and requirements of any regulatory authority, and of the engineers
of any of the Landlord's insurance carriers, relating to the Demised Premises.

          13.2      If and to the extent that, as a result of any act or
omission by Tenant, the rate of fire insurance applicable to the Building in
computing fire insurance premiums is increased over the rate that otherwise
would apply, then in addition to any other remedies which Landlord has for any
such act or omission or violation of this Lease, Tenant shall reimburse Landlord
for all increases in Landlord's fire insurance premiums that result solely and
directly from the increase in the rate; such reimbursement to be made on the
first day of the month following the date on which Landlord pays any amount on
account of the increased fire insurance premiums. In any action or proceeding in
which Landlord and Tenant are parties, a schedule or `makeup' of rates for the
Building or Demised Premises issued by the body making fire insurance rates for
the Building or Demised Premises shall be presumptive evidence of the facts
stated in the schedule or `makeup' and of the several items and charges in the
fire insurance rate then applicable to the Building or Demised Premises.

          13.3      Neither Landlord nor its agents, employees or invitees
("Landlord's Parties") shall be liable for any injury or damage to persons or
property resulting from fire, explosion, falling matter, steam, gas,
electricity, water, rain or snow or leaks from any part of the Building, or from
the pipes, appliances or plumbing works or from the root, street or subsurface
or from any other place or from dampness or by any other cause of whatsoever
nature, unless the injury or damage is proximately caused by or due to the gross
negligence of Landlord's Parties.

          13.4      Landlord's Parties shall not be liable for any damages which
Tenant sustains, if any window of the Demised Premises is temporarily broken or
temporarily closed, darkened or bricked up for any reason whatsoever, excluding
only Landlord's unreasonable, grossly negligent and arbitrary acts; and Tenant
shall not be entitled to any compensation or abatement of Total Rents or to any
release from any of Tenant's obligations under this Lease, nor shall the same
constitute an eviction.

<PAGE>

          13.5      (a)  Subject to Section 13.8(a) hereof, Tenant shall
indemnify, defend and hold Landlord, its agents, employees and invitees harmless
from and against any and all liability, claims, suits, demands, judgments,
costs, damages, fines, interest and expenses (including attorneys' fees and
disbursements) incurred or suffered by Landlord, its agents, employees or
invitees by reason of any breach, violation or nonperformance by Tenant, or its
agents, employees, licensees, invitees or contractors of any covenant or
provision of this Lease, or by reason of any damage to persons or property
caused by moving property of or for Tenant in or out of the Building, or by the
installation or removal of furniture or other property of or for Tenant or by
reason of or arising out of the acts, omissions, negligence or improper conduct
of Tenant, or its agents, employees, licensees, invitees or contractors in the
preparation, alteration, use or occupancy of the Demised Premises. Subject to
the provisions of Section 12.2, Tenant shall have the right, at Tenant's
expense, to participate in the defense of any action or proceeding brought
against Landlord, its agents, employees or invitees and in negotiations for
settlement thereof if pursuant to this Section 13.5(a), Tenant would be
obligated to reimburse Landlord for costs, damages, fines, interest or expenses
incurred or suffered by Landlord. Notwithstanding any such participation by
Tenant, Landlord shall have the sole right to conduct the defense or to agree to
any such settlement, Tenant's participation being advisory and non-controlling
only.

                    (b)  Subject to Section 13.8(b) hereof, Landlord shall
indemnify, defend and hold Tenant, its agents, employees and invitees harmless
from and against any and all liability, claims, suits, demands, judgments,
costs, damages, fines, interest and expenses (including attorneys' fees and
disbursements) incurred or suffered by Tenant, its agents, employees or invitees
by reason of any breach, violation or nonperformance by Landlord, or its agents,
employees, licensees, invitees or contractors of any covenant or provision of
this Lease, or by reason of any damage to persons or property caused by moving
property of or for Landlord in or out of the Building, or by reason of or
arising out of the acts, omissions, negligence or improper conduct of Landlord,
or its agents, employees, licensees, invitees or contractors. Landlord shall
have the right, at Landlord's expense, to participate in the defense of any
action or proceeding brought against Tenant, its agents, employees or invitees
and in negotiations for settlement thereof if pursuant to this Section 13.5(b),
Landlord would be obligated to reimburse Tenant for costs, damages, fines,
interest or expenses incurred by Tenant. Notwithstanding any such participation
by Landlord, Tenant shall have the sole right to conduct the defense or to agree
to any such settlement, Landlord's participation being advisory and non-
controlling only.

                    (c)  Landlord's and Tenant's respective obligations under
this Section 13.5 shall survive the termination of this Lease.

          13.6      Tenant shall notify Landlord of all fires and accidents in
the Demised Premises promptly after Tenant is aware of such fire or accident.

          13.7      Absent Landlord's fraud, Tenant will look solely to
Landlord's estate and interest in the Land and the Building, or the lease of the
Building or of the Building, and the Demised Premises, for the satisfaction of
any right or remedy of Tenant for the collection of a judgment (or other
judicial process) requiring the payment of money by Landlord, in the event of
any liability by Landlord, and no other property or asset of Landlord and no
property of any owner, partner, shareholder or principal of Landlord shall be
subject to levy, execution, attachment, or other enforcement procedure for the
satisfaction of Tenant's remedies under or with respect to this Lease, the
relationship of Landlord and Tenant hereunder, or Tenant's use and occupancy of
the Demised Premises, or any other liability of Landlord to Tenant.

          13.8      (a)  Landlord will include in its fire insurance policies,
clauses pursuant to which the companies that issue the policies either or both
(i) waive all rights of subrogation against Tenant with respect to losses
payable under those policies, and (ii) agree that those policies shall not be
invalidated if the insured party waives in writing before a loss occurs any and
all right of recovery against any party for losses covered by those policies. If
any additional premium is

                                       27
<PAGE>

charged for either or both of the clauses, then Landlord shall notify Tenant of
that additional premium and if, within 30 days after receiving that notice,
Tenant does not agree to pay that additional premium upon receipt of Landlord's
invoice therefor, or if Tenant does so agree, but thereafter fails to pay that
additional premium, then Landlord shall be released from the obligation to
obtain those clauses.

                    (b)  Tenant will obtain and maintain during the entire Term,
a fire insurance policy or policies covering the full replacement value of
Tenant's Personal Property, Tenant's Alterations and of all Fixtures and shall
include in each such policy, clauses pursuant to which the company that issues
that policy either or both (i) waives all rights of subrogation against Landlord
with respect to losses payable under that policy, and (ii) agrees that the
policy will not be invalidated if the insured waives in writing before a loss
occurs any or all right of recovery against any party for loss covered by that
policy. If any additional premium is charged for either or both of the clauses,
then Tenant shall notify Landlord of that additional premium and, if within 30
days after receiving that notice, Landlord does not agree to pay that additional
premium upon receipt of Tenant's invoice therefor, or if Landlord does so agree,
but thereafter fails to pay that additional premium, then Tenant shall be
released from the obligation to obtain those clauses.

                    (c)  Landlord waives any and all rights of recovery which it
might otherwise have against Tenant, its servants, agents and employees, in
respect of loss or damage occurring to the Building and the fixtures,
appurtenances and equipment therein, to the extent that the loss or damage is
covered by Landlord's insurance, notwithstanding that the loss or damage results
from the negligence or fault of Tenant, its servants, agents or employees.
Tenant waives any and all rights of recovery which it might otherwise have
against Landlord, Landlord's servants, agents and employees, and against every
other tenant in the Building which has executed a waiver similar in substance to
those described in this Section 13.8 in respect of loss or damage to Tenant's
Personal Property, Tenant's Alterations or to any Fixtures in the Demised
Premises, to the extent that the loss or damage is covered by Tenant's
insurance, notwithstanding that the loss or damage results from the negligence
or fault of Landlord, its servants, agents or employees or of such other tenant
and its servants, agents or employees.

                    (d)  Each of Landlord and Tenant will advise the other
promptly (i) if either or both of the clauses to be included in their respective
insurance policies pursuant to Sections 13.8(a) and 13.8(b) cannot be obtained,
(ii) if any such clause is obtained and thereafter is either canceled or an
increased premium is charged for the clause, (iii) if the terms of any policy
which would affect any such clause are changed, (iv) if any clause that
previously was not obtainable becomes obtainable and/or (v) if any clause that
previously was obtainable at an additional premium becomes obtainable at a lower
premium.

          13.9      Tenant will provide on or before the Commencement Date and
keep in force during the Term for the benefit of Landlord and Tenant a
commercial general liability insurance policy, written on an occurrence basis,
with limits of not less than Five Million dollars ($5,000,000.00) combined
single limit coverage protecting Landlord and Tenant against any liability
whatsoever occasioned by any occurrence on or about the Demised Premises or any
appurtenances thereto, together with worker's compensation insurance to the
extent required by law, and in the event a motor vehicle is to be used by Tenant
in connection with its business operation from the Demised Premises,
Comprehensive Automobile Liability Insurance coverage with limits of not less
than Five Million dollars ($5,000,000.00) combined singe limit coverage against
bodily injury liability and property damage liability arising out of the use by
or on behalf of Tenant, its agents and employees in connection with this Lease,
of any owned, non-owned or hired motor vehicles. Such policies are to be written
by good and solvent insurance companies satisfactory to Landlord (rated A or
better and Class X or higher by A.M. Best Company) and shall be in such limits
as Landlord may reasonably require. Such policy shall name Landlord, Landlord's
first mortgagee, Landlord's managing agent and such other parties as Landlord
shall require in writing from time to time as additional insureds. As of the
date of this Lease, Landlord reasonably requires limits of liability thereunder
of not less than the amount of Five Million dollars ($5,000,000) for bodily
injury and property damage, combined single limit. Tenant may satisfy its
liability insurance obligations hereunder by

                                       28
<PAGE>

way of $2,000,000.00 of premium coverage and the balance in umbrella coverage.
Such insurance may be carried under a blanket policy covering the Demised
Premises and other locations of Tenant if the required amounts of coverage for
the Demised Premises are not affected as a result of a claim involving another
location. Before the date on which such insurance first is required to be
carried by Tenant and thereafter, at least 15 days before the effective date of
renewal of any such policy, Tenant will deliver to Landlord either a duplicate
original of the aforesaid policy or a certificate evidencing such insurance. The
policy or certificate, as the case may be, shall contain an endorsement that
such insurance may not be canceled or modified except upon thirty days' notice
to Landlord.

          13.10     Landlord shall maintain during the term of this Lease a
policy or policies of insurance insuring the Building against loss or damage due
to fire and other casualties covered within the classification of fire and
extended coverage and malicious mischief, sprinkler leakage, water damage and
special extended coverage on the Building, on a 100% replacement cost basis.


                                  ARTICLE 14

                         DAMAGE BY FIRE OR OTHER CAUSE

          14.1      If (a) either or both of the Building and the Demised
Premises are partially or totally damaged or destroyed by fire or other cause (a
"Casualty"), whether or not the damage or destruction (either or both, the
"Damage") resulted from the fault or neglect of Tenant, or its employees,
agents, invitees or contractors, and (b) the amount of the proceeds of insurance
that is made available to Landlord for the purpose of repairing the Damage is
sufficient to pay the entire cost of repairing the Damage, then (if this Lease
has not been terminated as is provided in this Article 14) Landlord shall repair
the Damage at Landlord's expense (without limiting Landlord's rights under any
other provision of this Lease), provided that Landlord shall not be required to
repair or replace any of Tenant's Personal Property or Fixtures.

          14.2      (a)  If either or both of the Building and the Demised
Premises or access thereto are partially damaged or partially destroyed by a
Casualty, then the Total Rents shall be abated to the extent that the Demised
Premises have been rendered and remain untenantable during the period from the
date of the Damage to the date on which the Damage is repaired.

                    (b)  If the Demised Premises or a major part thereof are
totally (which shall be deemed to include substantially totally) damaged or
destroyed or rendered completely untenantable on account of a Casualty, then the
Total Rents shall abate for the period commencing on the date of the Damage and
shall end on the date on which Landlord has repaired the Damage, except that if
Tenant occupies a portion of the Demised Premises during that period and before
the date on which the Demised Premises are made completely tenantable, then
Total Rents allocable to that portion shall be payable form the date of that
occupancy.

                    (c)  If either or both of the Building and the Demised
Premises are totally damaged or destroyed by a Casualty or if the building in
which the Demised Premises are located is so damaged or destroyed by Casualty
(whether or not the Demised Premises are damaged or destroyed) so as to require
a reasonably estimated expenditure for repair or the Damage of more than 40
percent of the full insurable value of such building immediately prior to the
Casualty, then in either such case Landlord may terminate this Lease by giving
notice to Tenant to that effect within ninety (90) days after the date of the
Casualty. In such event, this Lease shall terminate on the tenth day after the
giving of the notice and the Total Rents shall be apportioned as of the
effective date of that Termination with respect to the undamaged portion of the
Demised Premises and as of the date of the Damage with respect to the damaged
portion of the Demised Premises (except as to those portions which were
reoccupied by Tenant). Landlord shall cause its architects or engineers to
estimate, after reasonable

                                       29
<PAGE>

investigation, in their reasonable opinion, within thirty (30) days after the
date of the Casualty, whether the Demised Premises will be untenantable
following the date of the Casualty for a period of fifteen (15) months; Landlord
shall provide a copy of that estimate to Tenant promptly upon its receipt by
Landlord, and Tenant may, if the estimate is for more than fifteen (15) months,
terminate this Lease by notice to Landlord within 30 days from the date on which
Tenant receives the copy of the estimate.

          14.3      Landlord shall not be obligated to pay any damages,
compensation or claim for inconvenience, loss of business or annoyance that
arises from any repair or restoration of any portion of the Demised Premises or
of the Building pursuant to this Article 16 or for any delay in completing
repairs or restoration which arises by reason of adjustment of insurance, labor
troubles or other causes beyond Landlord's reasonable control.

          14.4      Notwithstanding any of the foregoing provisions of this
Article 14, if Landlord or the lessor of any superior lease or the holder of any
superior mortgage is unable to collect all of the proceeds (including rent
insurance proceeds) under policies of insurance covering Damage by a Casualty
because of an illegal act by Tenant or a violation of insurance policy
requirements by Tenant or by any of its employees, agents or contractors, or by
reason of Tenant's failure fully to cooperate with Landlord, the superior lessor
or the superior mortgagee in applying for the insurance proceeds, then in the
case of that inability to collect and without prejudice to any other remedies
which may be available to Landlord against Tenant, Tenant shall pay to Landlord,
upon receipt of Landlord's invoice therefor, an amount that is equal to the
amount of those uncollected insurance proceeds, and there shall be no abatement
of Total Rents until that amount is fully paid by Tenant.


                                  ARTICLE 15

                   ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

          15.1      (a)  Tenant shall not (i) assign or otherwise transfer this
Lease or the term and estate hereby granted (ii) sublet the Demised Premises or
any part thereof or allow the same to be used or occupied by others or in
violation of Article 9, (iii) mortgage, pledge or encumber this Lease or the
Demised Premises or any part thereof in any manner by reason of any act or
omission on the part of Tenant or otherwise (each a "Transfer"); without in each
instance obtaining the prior written consent of Landlord, which consent shall
not be unreasonably withheld, conditioned or delayed.

                    (b)  For purposes of this Article 15, (i) the transfer of a
majority of the issued and outstanding capital stock of any corporate tenant, or
of a corporate subtenant, or the transfer of a majority of the total interest or
of the general partnership interest in any partnership tenant or subtenant,
however accomplished, whether in a single transaction or in a series of related
or unrelated transactions, or the creation of new stock by which an aggregate of
more than fifty (50%) percent of Tenant's stock shall be vested in a party or
parties who are nonstockholders as of the date hereof, shall be deemed a
Transfer except that the sale of the capital stock of any corporate tenant by
the corporate tenant or by any holder of such stock through the `over-the-
counter market' or through any recognized stock exchange, other than by holders
of such stock who are deemed "insiders" within the meaning of the Securities
Exchange Act of 1934, as amended, shall not be deemed to be a Transfer, (ii) a
takeover agreement of a corporate tenant shall be deemed a Transfer, (iii) any
person or legal representative of Tenant, to whom Tenant's interest under this
Lease passes by operation of law, or otherwise, shall be bound by the provisions
of this Article 15, and (iv) a modification, amendment or extension of a
sublease shall be deemed a Transfer. For the purposes of this Article 15, Tenant
acknowledges that it will be liable to pay to Landlord, upon demand, Landlord's
reasonable attorneys' fees and reasonable out-of-pocket expenses incurred in
connection with reviewing Tenant's request for a Transfer.

          15.2      The provisions of Section 15.1 hereof shall not apply to
transactions with an entity into or with

                                       30
<PAGE>

which Tenant is merged or consolidated or with an entity to which substantially
all of Tenant's assets are transferred (provided such merger or transfer of
assets is for a good business purpose and not principally for the purpose of
transferring the leasehold estate created hereby, and provided further, that
such corporation or entity has a net worth at least equal to the net worth of
Tenant immediately prior to such merger or transfer) or, if Tenant is a
partnership with a successor partnership, nor shall the provisions of clauses
(a) and (b) of Section 15.1 apply to transactions with an entity which wholly
owns or is wholly owned by Tenant or which has identical ownership as Tenant.
Notwithstanding anything to the contrary in this Lease, Tenant may permit any
corporation or other business entities which control, are controlled by, or are
under common control with Tenant (herein referred to as a "Related Entity") to
sublet all or part of the Demised Premises for any of the purposes permitted to
Tenant, or receive an assignment of this Lease provided that (i) Tenant shall
not be in default in the performance of any of its obligations under this Lease
beyond the expiration of applicable notice and cure periods and (ii) prior to
such subletting or assignment, Tenant furnishes Landlord with the name of any
such Related Entity, together with a certification of Tenant, and such other
proof as Landlord may reasonably request, that such subtenant/assignee is a
Related Entity of Tenant. For the purposes hereof, "control" shall be deemed to
mean (a) ownership of not less than ten percent (10%) of all of the voting stock
of any publicly traded corporation plus voting control of such corporation or
(b) ownership of more than 50% of the ownership interests in any non-publicly
traded corporation or in any other business entities.

          15.3      Any Transfer, whether made with Landlord's consent as
required by Section 15.1 hereof or without Landlord's consent pursuant to
Section 15.2 hereof, shall be made only if, and shall not be effective until,
the recipient of a Transfer ("Transferee") executes, acknowledges and delivers
to Landlord a recordable agreement, in form and substance reasonably
satisfactory to Landlord, whereby the Transferee assumes the obligations and
performance of this Lease and agrees to be personally bound by all of the
covenants, agreements, terms, provisions and conditions of this Lease to be
performed or observed by Tenant and whereby the Transferee agrees that the
provisions of Section 15.1 shall, notwithstanding the Transfer, continue to be
binding upon it in the future. Notwithstanding any Transfer, whether or not in
violation of the provisions of this Lease, and notwithstanding the acceptance of
Annual Net Rent by Landlord from a Transferee or any other party, Tenant shall
remain fully and primarily liable for the payment of the Annual Net Rent and
Additional Rent due and to become due under this Lease and for the performance
of all of the covenants, agreements, terms, provisions and conditions of this
Lease to be performed or observed by Tenant.

          15.4      The liability of Tenant for the due performance by Tenant of
this Lease, shall not be discharged, released or impaired in any respect by any
agreement or stipulation made by Landlord with any Transferee, extending the
time of or modifying any of the obligations contained in this Lease, or by any
waiver or failure of Landlord to enforce any of the obligations of this Lease,
and Tenant shall continue to be liable under this Lease. If any such agreement
or modification operates to increase Tenant's obligations under this Lease, the
liability under this Section 15.4 of Tenant (unless Tenant shall have expressly
consented in writing to such agreement or modification), shall continue to be no
greater than if such agreement or modification had not been made. To require
Tenant to meet its obligations as described in this Section 15.4, no demand or
notice of any default other than demands and notices required under this Lease,
copies of which Landlord will give to Tenant, shall be required; Tenant hereby
waives any such demand or notice.

          15.5      Tenant shall not, without the consent of Landlord (including
approval of the exact wording of any listing or advertisement), list or
advertise or permit to be listed or advertised, or offered to any broker for
listing or advertisement, all or any part of the Demised Premises. Landlord
shall not unreasonably withhold, condition or delay such consent, provided that
in no event shall Landlord be required to consent to any advertising of the
Demised Premises for a rent that is less than the rent payable under this Lease
and in no event shall any public advertisement of the Demised Premises mention
the rental rate. In addition, Tenant shall not list or advertise the Demised
Premises at any time when Landlord has Competing Space in the Building that is
available for lease or that Landlord has commenced leasing efforts for, except
that such restriction shall not apply to up to 15,000 rentable square feet of
the Demised Premises that Tenant attempts to sublease

                                       31
<PAGE>

commencing at or around the Rent Commencement Date (the "Initial Sublease
Area"). "Competing Space" shall mean any space which has a square foot size that
is equal to or larger than 75% of the square footage of the portion of the
Demised Premises that Tenant is attempting to sublease.

     15.6      If Tenant desires to enter into any Transfer which requires
Landlord's prior consent pursuant to this Article 15, it shall notify Landlord
of such intention before offering the same to any party either directly or
through any broker. In no event may such an offer be made to an occupant of any
part of the Building nor may such an offer be made to any other prospective
Transferee unless, to the best of Tenant's knowledge, the prospective Transferee
has not negotiated with Landlord for space in the Building within the six (6)
month period prior to the time Landlord is first notified of Tenant's intention
to Transfer. If a Transfer is thereafter arranged with a permitted Transferee,
Tenant shall, at least thirty (30) days before the proposed date of consummation
thereof, notify Landlord thereof and deliver to Landlord:

                    (i)    Commercially adequate information concerning the
nature of the business and the financial status of the proposed Transferee;

                    (ii)   A copy of the proposed sublease or assignment
agreement or signed term sheet or letter of intent therefor, as the case may be,
signed by the proposed subtenant or assignee and by Tenant (or, in lieu thereof,
a term sheet or letter of intent signed by the proposed subtenant or assignee
and Tenant), which in either case shall contain all the substantive terms of the
proposed sublease or assignment, including, if a sublease is involved, the term,
the rent and date of commencement thereof or, if an assignment is involved, the
effective date thereof and the amount of all consideration and to whom payable;
and

                    (iii)  Any other related information reasonably required by
Landlord.

     15.7      Within the thirty (30) day period described in Section 15.6
hereof, Landlord shall have the right, exercisable by sending notice to Tenant,
to exercise any of the following rights:

               (a)  consent or refuse to consent to the Transfer; provided that
if Landlord does not exercise any of the rights or options set forth in
subsections 15.7(b), (c) or (d) below, Landlord agrees not to unreasonably
withhold or delay its consent to any such Transfer, provided that in no event
shall Tenant assign this Lease or sublease any portion of the Demised Premises
to any tenant then occupying or leasing space in the Building or in the building
to be built on Parcel 1 at any time when Landlord, or the owner of Parcel 1, has
space available which would satisfy the needs of such tenant, and in no event
shall Landlord be obligated to consent to an assignment or sublease with any
such tenant;

               (b)  in the case of a proposed assignment, cancel this Lease as
to the space proposed to be assigned, in which event such cancellation shall
become effective on the date of the proposed assignment. If such cancellation is
only for part of the Demised Premises, then equitable adjustments shall be made
to the Annual Net Rent and Additional Rent, based upon the Rentable Area of the
Demised Premises that is cancelled;

               (c)  in the case of a proposed subletting for a term which will
expire before the expiration of this Lease, elect to recapture the portion of
the Demised Premises proposed to be sublet for only the term of the proposed
sublet. In such event Tenant's Annual Net Rent and Additional Rent will be
reduced during such period of recapture by the lesser of (i) the same amount as
Tenant would have received from the proposed subtenant, or (ii) the amount of
Tenant's obligations under this Lease for the portion of the space recaptured.
The recapture of the portion of the Demised Premises shall become effective on
the date specified in the proposed sublease, term sheet or letter of intent; and

                                       32
<PAGE>

               (d)  in the case of a proposed subletting, elect to accept a
sublease as subtenant of Tenant on the terms offered to the proposed subtenant,
except that (i) no provision of such sublease shall be any more restrictive upon
the rights of Landlord as such subtenant than are the provisions of this Lease
upon the rights of Tenant, (ii) there shall be no limitation as to use or
prohibition against a further subletting and (iii) Tenant shall not be required
to do any work for Landlord.

     Notwithstanding the foregoing, if Tenant presents Landlord with a signed
term sheet under Section 15.6 above then Landlord may only exercise its rights
under Sections 15.7(b), (c) or (d) hereof if it so notifies Tenant, in writing,
within five (5) business days after receipt of the signed term sheet.

     If Landlord exercises its rights under Section 15.7(c) or (d) above with
respect to less than all of the Demised Premises, then Landlord shall not
thereafter lease or sublease, as the case may be, the portion of the Demised
Premises in question to a Competitor. Landlord shall present the name of any
proposed tenant or subtenant to Tenant, and such entity shall only be deemed to
be a "Competitor" if Tenant can prove, to Landlord's reasonable satisfaction,
that such entity is a competitor of Tenant, within ten (10) business days after
submission of the name of the entity to Tenant.

     15.8      Intentionally Omitted.

     15.9      If Landlord consents to any Transfer that occurs during the
Extension Term, Tenant shall in consideration therefor pay to Landlord, as
Additional Rent:

               (i)  in the case of an assignment, an amount equal to all sums
and other consideration paid to Tenant (after subtracting all actual, out-of-
pocket costs incurred by Tenant in connection therewith) by or for the account
of the assignee for or by reason of such assignment (including, but not limited
to, sums paid for the sale of Tenant's fixtures, leasehold improvements,
equipment, furniture, furnishings or other personal property, less, in the case
of a sale thereof, the then "book" or fair market value thereof determined by
Tenant, subject to Landlord's reasonable approval); and

               (ii) in the case of a sublease, any rents, additional charges or
other consideration payable under the sublease to Tenant by the subtenant (after
subtracting all actual, out-of-pocket costs incurred by Tenant in connection
therewith), the aggregate of which exceeds the Annual Net Rent and Additional
Rent accruing during the term of the sublease in respect of the subleased space
(at the rate payable by Tenant) under this Lease (including sums paid for the
sale or rental of Tenant's fixtures, leasehold improvements, equipment,
furniture or other personal property, less, in the case of the sale thereof,
then "book" or fair market value thereof, determined by Tenant, subject to
Landlord's reasonable approval).

The sums payable under this Section 15.9 shall be paid to Landlord as and when
paid by the Transferee to Tenant. This Section 15.9 shall not apply to any
Transfer that occurs during the initial Term of this Lease.

     15.10     Landlord's consent to any Transfer shall not be deemed or
construed to modify, amend or affect the terms and provisions of this Lease, or
Tenant's obligations hereunder, which shall continue to apply to all of the
occupants of the Demised Premises (including Tenant and the Transferee) in
addition to the terms of the sublease or assignment and, if and to the extent of
a conflict between this Lease and the sublease or assignment, only as between
Landlord, on the one hand, and Tenant and the Transferee, on the other, this
Lease shall be controlling in the same manner as if the Transfer had not been
made. Notwithstanding any Transfer, Tenant shall remain fully liable for the
payment of Annual Net Rent and Additional Rent and for the performance by Tenant
of all of its other obligations under this Lease. If Tenant defaults in the
payment of any rent, Landlord is authorized to collect any rents due or accruing
from any Transferee or other occupant of the Demised Premises and to apply the
net amounts collected to the Total Rent, and the receipt of any such amounts by
Landlord from a Transferee or other occupant of the Demised Premises, shall not
be deemed or construed as releasing Tenant from Tenant's

                                       33
<PAGE>

obligations under this Lease or the acceptance of that Transferee as a direct
tenant.

     15.11     In each subletting permitted by this Article 15, and in each
further subletting with the consent of Landlord, Tenant shall include, or cause
to be included, in the sublease a provision prohibiting the assignment of the
sublease or subletting thereunder without the consent of the Landlord (which
Landlord may withhold in its sole but reasonable discretion) in each instance
obtained. If the sublease or any sublease is assigned or further sublet without
the consent of Landlord obtained in each instance, then Tenant shall immediately
terminate such sublease, or arrange for the termination thereof, and proceed
expeditiously to have the occupant thereunder dispossessed.

     15.12     In no event shall Tenant allow the Demised Premises to be
occupied by a total of more than four (4) tenants (including Tenant).

     15.13     If Tenant requires expansion space at any time during the Term
and Landlord is willing to lease to Tenant the amount of space required by
Tenant, substantially equal in size and configuration and competitive with
respect to rents as other space (all as reasonably determined by Tenant) that
maybe available at the Building by sublease or assignment, then Tenant shall not
become the sublessee or assignee of any other tenant in the Building or an
occupant of any of such tenant's space without Landlord's consent.


                                  ARTICLE 16

                                EMINENT DOMAIN

     16.1      If the whole of the Demised Premises, or such part thereof as
will render the remainder untenantable, shall be acquired or condemned for any
public or quasi-public use or purpose, this Lease shall end as of the date of
the vesting of title in the condemning authority (either through court order or
by voluntary conveyance by Landlord in lieu of condemnation) with the same
effect as if said date were the Expiration Date. If only a part of the Demised
Premises shall be so acquired or condemned, then, except as otherwise provided
in this Article, this Lease and the Term shall continue in force and effect but
from and after the date of the vesting of title, the Annual Net Rent shall be an
amount which bears the same ratio to the Annual Net Rent payable immediately
prior to such condemnation pursuant to this Lease as the value of the untaken
portion of the Demised Premises (appraised after the taking and repair of any
damage to the Building pursuant to this Section) bears to the value of the
entire Demised Premises immediately before the taking and any additional rent
payable or credits receivable pursuant to Article 3 shall be adjusted to reflect
the diminution of the Demised Premises. The value of the Demised Premises before
and after the taking shall be determined for the purposes of this Section by an
independent appraiser, said appraiser shall be chosen by arbitration pursuant to
Article 35. If only a part of the Building shall be so acquired or condemned,
then (a) whether or not the Demised Premises shall be affected thereby,
Landlord, at Landlord's sole option, may give to Tenant, within sixty (60) days
next following the date upon which Landlord shall have received notice of
vesting of title, thirty (30) days' notice of termination of this Lease, and (b)
if the part of the Building so acquired or condemned shall contain more than
twenty-five percent (25%) of the total area of the Demised Premises immediately
prior to such acquisition or condemnation, or if, by reason of such acquisition
or condemnation, Tenant no longer has reasonable means of access to the Demised
Premises, Tenant may give to Landlord, within sixty (60) days following the date
upon which Landlord shall have received notice of vesting of title, thirty (30)
days' notice of termination of this Lease. Any dispute concerning the exercise
by Landlord or Tenant of an option to terminate this Lease pursuant to this
Section 16.1 shall be submitted to arbitration pursuant to Article 35 below. In
the event any such thirty (30) days notice of termination is given by Landlord
or Tenant, this Lease shall terminate upon the expiration of said thirty (30)
days with the same effect as if the date were the Expiration Date. If part of
the Demised Premises shall be so acquired or condemned, and this Lease shall not
be terminated pursuant to the provisions

                                       34
<PAGE>

of this Section, Landlord, at Landlord's expense, shall restore that part of the
Demised Premises not so acquired or condemned to a self-contained rental unit.
In the event of any termination of this Lease pursuant to the provisions of this
Section, the Annual Net Rent and Additional Rent shall, as to any portion of the
Demised Premises that was not taken, be apportioned as of the date of such
termination and any prepaid portion of Annual Net Rent and Additional Rent for
any period after such date shall be refunded by Landlord to Tenant.

     16.2      In the event of any such acquisition or condemnation of all or
any part of the Building, Landlord shall be entitled to receive the entire award
for any such acquisition or condemnation. Except as specifically provided
herein, Tenant shall have no claim against Landlord or the condemning authority
for the value of any unexpired portion of the Term and Tenant hereby expressly
assigns to Landlord all of its right, title and interest in and to any such
award, and also agrees to execute any and all further documents that may be
required in order to facilitate the collection thereof by Landlord. Nothing
contained in this Section shall be deemed to prevent Tenant from making a
separate claim in any condemnation proceedings for all moving and relocation
expenses and for the value of any Tenant's Personal Property which would be
removable at the end of the Term pursuant to the provisions of Section 10.6
hereof.

     16.3      If the use or occupancy of all or any part of the Demised
Premises shall be condemned or taken for any public or quasi-public use or
purpose during the Term for a period not in excess of six (6) months, this Lease
shall be and remain unaffected by such condemnation or taking and Tenant shall
continue responsibility for all of its obligations hereunder and it shall
continue to pay the rent in full. In the event of any such condemnation or
taking, Tenant shall be entitled to appear, claim, prove, and receive the entire
award unless the period of temporary use or occupancy extends beyond the
Expiration Date, in which event Landlord shall be entitled to appear, claim,
prove, and receive the entire award as represents the cost of restoration of the
Demised Premises and the balance of any such award shall be apportioned between
Landlord and Tenant as of the Expiration Date. At the termination of such public
or quasi-public occupancy prior to the Expiration Date, Tenant will, at its own
expense, restore the Demised Premises as nearly as possible to the condition in
which they were prior to the condemnation or taking, provided, however, that
Tenant shall have no obligation to expend any sum in excess of the condemnation
proceeds received by Tenant under this Section 16.3 to restore the Demised
Premises in accordance with this Section. Notwithstanding the preceding
provisions of this Section, any lump sum award received by Tenant as
compensation for temporary use and occupancy of the Demised Premises shall be
delivered forthwith to Landlord to be held by Landlord in trust for the making
of payments by Tenant as provided in this Lease.

     16.4      If the grade of any street upon which the Building is situated or
abuts shall be changed by any competent authority, this Lease shall nevertheless
continue in full force and effect, and Landlord shall be entitled to collect
from such authority the entire award that may be made in such proceedings.
Tenant hereby expressly assigns to Landlord all of its right, title, and
interest in or to every such award and also agrees to execute any and all
further documents that may be required in order to facilitate the collection
thereof by Landlord.

     16.5      Landlord shall promptly provide Tenant with any condemnation
notices received by Landlord, if the proposed condemnation would have any
material effect on the Demised Premises, access thereto, or Tenant's parking,
and, upon request, will provide Tenant with copies of relevant pleadings in any
condemnation action.


                                  ARTICLE 17

                      ACCESS TO DEMISED PREMISES, CHANGES

     17.1      (a)  Tenant shall permit Landlord to erect, use and
maintain pipes, ducts and conduits

                                       35
<PAGE>

(collectively referred to as "Conduits"), in addition to those Conduits that are
in place on the Commencement Date, in and through the Demised Premises if the
Conduits are installed adjacent to or concealed behind walls and ceilings. To
the extent reasonably practicable, Landlord shall install the Conduits by such
methods and at such locations as will not materially interfere with or impair
Tenant's layout or use of the Demised Premises, provided that (i) Landlord shall
exercise all reasonable efforts to minimize inconvenience to Tenant in
connection therewith and (ii) no action taken by Landlord under this Article 17
shall impede access to, reduce the size or otherwise diminish the utility of the
Demised Premises in any material respect, including any services provided
thereto, and Landlord agrees to use commercially reasonable efforts to locate
any such Conduits within the core areas of the Building.

               (b)  Landlord and its agents and designees shall have the right
to enter the Demised Premises as follows:

          Upon reasonable prior notice (except in emergencies or in
circumstances which do not permit the giving of such notice, in either of which
cases no notice shall be required) to Tenant or to any authorized employee of
Tenant at the Demised Premises, at reasonable times during Business Hours, for
the following purposes:

                    (1)  To make such repairs and Alterations as Landlord deems
reasonably necessary or which Landlord is required or has the right to make
under this Lease or under any other lease in the Building. Landlord may take all
materials into and upon the Demised Premises that are required for those
repairs, alternations or the construction work at such time as those materials
are required, provided that Landlord shall not create a safety hazard or leave
materials in the Demised Premises for longer than is reasonably necessary.

                    (2)  To inspect the Demised Premises for reasons specified
in Landlord's notice.

                    (3)  To exhibit the Demised Premises to prospective
purchasers or lessees of the Building or of any interest in the Building or to
prospective mortgagees, or to the holder of any mortgage on either or both of
the Land and the Building.

                    (4)  To comply with all Laws, as identified in Landlord's
notice.

                    (5)  To comply with the request to enter the Demised
Premises of any receiver, trustee, assignee for the benefit of creditors,
sheriff, marshall or a bearer of a court order, who Landlord reasonably believes
is entitled to enter the Demised Premises (but that compliance shall not be
deemed a recognition by Landlord that the person or official requesting the
entry has any right, interest or authority).

                    (6)  To comply with the demand of any agency, department or
bureau of any government.

               (c)  Except as otherwise specifically provided in this Lease, the
proper exercise by Landlord of any right described in this Section 17.1 shall
not constitute a total or partial eviction of Tenant, and shall not entitle
Tenant to abate its Total Rents or to make any claim against Landlord by reason
of that exercise or by reason of interruption of Tenant's business, or
otherwise. In exercising its rights under this Section 17.1, Landlord will use
reasonable diligence in order to minimize disturbance to Tenant, but Landlord
shall not be required to exercise its rights in such manner as will result in
its paying overtime or premium pay to employees.

     17.2      Landlord may change the arrangement or location of parking areas,
common areas, sidewalks,

                                       36
<PAGE>

public entrances, passageways, doors, doorways, corridors, elevators, stairways,
toilets or other parts of the Building or the Project, except that the Landlord
may not cut off access to the Building and shall not unreasonably obstruct
access to, or unreasonably interfere with Tenant's use or enjoyment of, the
Demised Premises and provided that Landlord may only make any such change within
the portion of the Building that is building A if such change is required by
Law, required in connection with a necessary repair or replacement or required
in connection with the normal and efficient operation of the Building. The
exercise by Landlord of any right described in this Section 17.2 shall not
constitute a total or partial eviction of Tenant, and shall not entitle Tenant
to abate its Total Rents or to make any claim against Landlord.

     17.3      Neither this Lease nor any use by Tenant of any public area or
convenience will give Tenant any right or easement for that use, and Landlord
may regulate or discontinue that use upon reasonable prior notice to Tenant, to
the extent possible, at any time and from time to time without liability to
Tenant and without affecting Tenant's obligations under this Lease.

     17.4      Twelve months before the expiration of the Term, Landlord may
(upon reasonable prior notice to Tenant, which notice may be oral) exhibit the
Demised Premises to prospective tenants.

     17.5      If Tenant or any authorized employee of Tenant is not personally
present to permit entry into the Demised Premises at any time when entry into
the Demised Premises is necessary by reason of emergency, then Landlord and
Landlord's agents may forcibly enter the Demised Premises without rendering
Landlord or its agents liable for such entry (if Landlord and Landlord's agents
accord reasonable care to Tenant's property) and without in any manner affecting
this Lease. Tenant shall not be liable to Landlord or Landlord's agents for any
injury or damage caused by Landlord's or Landlord's agent's exercise of
Landlord's rights under this Article 17.


                                  ARTICLE 18

                                    DEFAULT

     18.1      This Lease and the term and estate granted by this Lease are
subject to the limitation that if (a) Tenant makes an assignment of Tenant's
property for the benefit of creditors, or (b) Tenant files a voluntary petition
under any bankruptcy or insolvency law (either, a "Creditor's Law"), or (c) an
involuntary petition alleging an act of bankruptcy or insolvency is filed
against Tenant under a Creditor's Law, or (d) a petition is filed by or against
Tenant under the reorganization provisions of any Creditor's Law, or (e) a
petition is filed by Tenant under the arrangement provisions of any Creditor's
Law, or (f) a petition by Tenant under the arrangement provisions of any
Creditor's Law, or (g) a permanent receiver of Tenant or for Tenant's property
is appointed, then in any of those six events Landlord may (i) if the event
occurs with the consent or acquiescence of Tenant, at any time after Landlord
becomes aware or receives notice of the occurrence, or (ii) if the event occurs
without Tenant's consent or acquiescence, at any time after the event continues
for 60 days, give to Tenant a notice of intention to end the Term at the
expiration of five days from the date of service of Landlord's notice of
intention, and at 5:00 P.M. on the last day of the five-day period, this Lease
and the Term and estate granted by this Lease, whether or not the Term has
commenced, shall terminate with the same effect as if that day were the
Expiration Date, but Tenant shall remain liable for damages as provided in
Article 20.

     18.2      If any of the following events ("Events of Default") occurs, then
Landlord may give to Tenant a notice of intention to end the Term in which
event, this Lease and the Term and the estate granted by this Lease, whether or
not the Term has commenced, will terminate at 5:00 p.m. on the day specified in
Landlord's notice to Tenant, with the same effect as if that time were the
Expiration Date, but Tenant shall remain liable for damages as provided in
Article 20:

                                       37
<PAGE>

               (a)  If Tenant defaults in the payment of any of the Annual Net
Rents or any scheduled payment of Additional Rent for more than five (5) days
after the day on which the payment is due, provided that Tenant shall be
entitled, not more than one (1) time in any twelve (12) month period, to written
notice that a payment was not made when due, and ten (10) days after receipt
thereof, in which to make the payment, before being in default hereunder.

               (b)  If Tenant fails to pay any unscheduled payment of Additional
Rent within thirty (30) days after receipt of an invoice therefor from Landlord.

               (c)  If Tenant defaults in the performance of any obligation
under Article 9 and if that default is not cured by Tenant within 24 hours after
Landlord has given to Tenant a notice specifying the default if the default
consists of an illegal use or a use that presents a health or safety risk, and
otherwise within two (2) business days after notice from Landlord; in any event,
Tenant shall have such additional time as is reasonably necessary to make any
necessary restorations to the Demised Premises as a result thereof, as long as
Tenant promptly commences the same and diligently pursues the restorations to
completion.

               (d)  If this Lease or the Term or the estate granted by this
Lease would or does by operation of law or otherwise devolve upon any person or
entity other than Tenant, except in accordance with Article 15.

               (e)  if Tenant abandons the Demised Premises (which shall not
consist of merely failing to occupy the Demised Premises).

               (f)  If Tenant does or permits anything (other than as provided
in paragraphs (a) and (b) of this Section 18.2) to be done or to exist, whether
by action or inaction, in violation of any of Tenant's obligations under this
Lease, and Tenant fails to remedy that violation within 15 days after Landlord
has given to Tenant a notice specifying the violation, except that (i) if the
violation cannot be completely remedied within the period of 15 days, and (ii)
the continuation of the violation for the period that Landlord reasonably
estimates is required to completely remedy the violation will not (x) subject
Landlord to the payment of any fine or penalty or to criminal prosecution or
subject either or both of the Land and Building to lien or sale, or (y) result
in a violation of, or the termination of, any mortgage or any ground or
underlying lease, and (iii) within the 15-day period, Tenant notifies Landlord
of Tenant's intention to completely remedy the violation with due diligence, and
(iv) within the 15-day period Tenant commences and thereafter diligently and
continuously takes all steps necessary to completely remedy the violation and
does completely remedy the violation within such time after the date of
Landlord's notice as reasonably is necessary, then Landlord shall not have the
right to give the notice of termination to end the Term as described in this
Section 18.2.


                                  ARTICLE 19

                       RE-ENTRY BY LANDLORD, INJUNCTION

     19.1      If an Event of Default occurs, then Landlord and Landlord's
agents and employees may at any time thereafter, re-enter all or any part of the
Demised Premises, by summary dispossess proceedings or by any action or
proceeding at law (a "Re-entry") without Landlord's being liable to indictment,
prosecution or damages as a result of the Re-entry (except for Landlord's gross
negligence or willful misconduct), so that upon the Re-entry Landlord will have,
hold and enjoy the Demised Premises free of any rights of Tenant under this
Lease. In the event of any termination of this Lease pursuant to Article 18 or
pursuant to any summary dispossess or other proceedings or action or any
provision of law by reason of Tenant's default (an "Early Termination") or in
the event of a Re-entry, Tenant shall pay to Landlord the Total Rents that are
payable by Tenant to Landlord up to the time of the Early Termination or Re-
entry, as the case may be, and in addition, shall pay to

                                       38
<PAGE>

Landlord damages as provided in Article 20.

     19.2      In case of a breach or a threatened breach by Tenant of this
Lease, Landlord shall have the right, to the extent permitted by law, of
injunction. Special remedies to which Landlord may resort under this Lease are
cumulative and are not intended to be exclusive of any other remedy or means of
redress to which Landlord lawfully may be entitled, and Landlord may invoke any
one or more remedies and means of redress allowed at law or in equity in the
same manner and to the same extent as if specific remedies were not provided for
in this Lease.

     19.3      If an Early Termination or a Re-entry occurs, then in either of
those events, Landlord may retain all monies that have been paid by Tenant to
Landlord, whether as advance rent, security or otherwise, and Landlord shall
credit those monies against the payment of any amounts of the Total Rents that
are due at the time of the Early Termination or the Reentry, or against the
payment of any damages that are payable by Tenant under Article 20 or pursuant
to Law.

     19.4      Tenant, for itself and on behalf of any person claiming through
or under it, including creditors of all kinds, waives any and all rights of
redemption granted under any present or future Laws if Tenant is being evicted
or dispossessed for any cause, or if Landlord obtains possession of the Demised
Premises by reason of a violation by Tenant of this Lease or otherwise.


                                  ARTICLE 20

                                    DAMAGES

     20.1      (a)  In the event of an Early Termination or a Re-entry, Tenant
shall pay to Landlord as damages, as Landlord elects, either:

                    (x)  An amount which, on the date of Early Termination or
Re-entry, as the case may be (each of which date is referred to as the
"Termination Date"), equals the aggregate of the Total Rents which would have
been payable by Tenant during the period (the "Default Period") commencing on
the Termination Date and ending on the Expiration Date (conclusively presuming
that all items constituting Additional Rent increase during the Default Period
at a rate that is equal to the average of the rate of increase of those items
that occurred during the shorter of the period from the Commencement Date to the
Termination Date or the three years immediately preceding the Termination Date),
less the fair and reasonable rental value of the Demised Premises for the
Default Period, both discounted to present value at the rate of 9% per annum, or

                    (y)  sums that are equal to the Total Rents which would have
been payable by Tenant had this Lease not so terminated or had the Re-entry not
occurred, which shall be paid by Tenant upon the due dates specified in this
Lease that occur during the Default Period, except that if Landlord relets all
or any part of the Demised Premises during the Default Period, then Landlord
shall credit Tenant with the net rents (after deduction of the reasonable
expense of reletting referred to in Section 20.1(b)) if, as and when those rents
are received by Landlord from the reletting. Any reletting may be for a period
shorter or longer than the remaining Term. Tenant shall not be entitled to
receive any excess of the rents collected under the reletting over the Total
Rents, or to a credit in respect of any rents from a reletting, except to the
extent that those rents actually are received by Landlord. Landlord shall use
commercially reasonable efforts to mitigate its damages, and the amount of the
credit to be given by Landlord to Tenant shall be reduced by the reasonable
costs incurred by Landlord in taking that action. If all or any part of the
Demised Premises are relet in combination with space that is not included within
the Demised Premises, then the rent received from that reletting and the
reasonable expenses of the reletting shall be apportioned to the portion of that
space that is within the Demised Premises in the percentage that the area of the
Demised Premises within

                                       39
<PAGE>

that space bears to the total area of that space.

               (b)  In addition to all damages recoverable under Section
20.1(a), Tenant shall pay to Landlord as damages an amount that is equal to the
reasonable expenses incurred by Landlord in terminating this Lease or in respect
of a Re-entry and in securing possession of the Demised Premises, including
reasonable attorneys' fees and disbursements, reasonable expenses of reletting
including altering and preparing the Demised Premises for new tenants, brokers'
commissions and attorneys' fees and disbursements, and all other reasonable
expenses incurred by Landlord in connection with the re-rental of the Demised
Premises.

               (c)  If all or any part of the Demised Premises is relet upon an
arm's-length basis for all or any part of the Default Period, then the amount of
rent provided for upon that reletting shall be conclusively presumed to be the
fair and reasonable rental value for the area so let. No such reletting shall
constitute, surrender or an acceptance of a surrender.

     20.2      Landlord may sue for the recovery of damages under this Article
20 or any installments on account thereof at any time and from time to time at
its election. Landlord shall not be required to postpone suit until the
Expiration Date. Nothing contained in this Article 20 shall be construed (a) to
limit or preclude recovery by Landlord from Tenant of any sums or damages to
which, in addition to the damages described in Section 20.1, Landlord would
lawfully be entitled by reason of Tenant's default, or (b) to limit or prejudice
Landlord's right to prove for and obtain as liquidated damages by reason of the
Early Termination of this Lease or a Re-entry, an amount that is equal to the
maximum allowed by any Law in effect at the time when, and governing the
proceedings in which, those damages are to be proved, whether or not the amount
is greater or less than any of the amounts referred to in Section 20.1.

     20.3      If Tenant fails to pay when due any installment of Annual Net
Rent or any payments of Additional Rent, then Tenant shall pay a late charge of
$.05 for each $1.00 of such installment or payment. The late charges imposed
hereunder are intended to compensate Landlord for additional expenses incurred
by Landlord in processing such late payments. Nothing herein contained shall be
intended to violate any applicable law, code or regulation, and all instances
all such changes shall be automatically reduced to any maximum applicable legal
rate or charge. Such charge shall be imposed monthly for each month that a late
payment is not made.


                                  ARTICLE 21

       LANDLORD'S AND TENANT'S RIGHTS TO PERFORM THE OTHER'S OBLIGATIONS

     21.1      If Tenant defaults in the performance of this Lease, then
Landlord may, but shall not be obligated to, take such action (the "Remedial
Action") which, if it had been taken by Tenant, would remedy that default (a)
immediately and without notice to Tenant in case of emergency, and (b) in any
other case if, after reasonable written notice, Tenant has failed to remedy the
default with all reasonable dispatch within the applicable grace period for
curing the default. The taking of the Remedial Action by Landlord shall not
constitute a waiver by it of the default. If Landlord makes any reasonable
expenditure or incurs any obligation for the payment of money in connection with
taking the Remedial Action or otherwise in connection with the default,
including reasonable attorneys' fees in instituting, prosecuting, or defending
any action or proceeding, then Tenant shall pay the amount thereof to Landlord,
with interest at the Interest Rate from the date of Landlord's expenditure until
the date of Tenant's payment, upon receipt of Landlord's invoice therefor.

     21.2      Notwithstanding any other provision contained herein to the
contrary, in the event that Landlord breaches any of its obligations under this
Lease (including without limitation the payment of the Tenant Improvement

                                       40
<PAGE>

Allowance) and such breach continues for a period of twenty (20) days after
receipt of written notice from Tenant, then if Tenant delivers a second notice
and Landlord fails to commence to cure such breach within five (5) days after
receipt of such second notice and thereafter diligently pursue the cure to
completion, or contest the existence of the breach in writing and in good faith,
then Tenant may, but shall not be obligated to, cure such breach and Landlord
shall reimburse Tenant's reasonable out-of-pocket costs incurred in connection
with effecting such cure with fifteen (15) days after Landlord's receipt of
Tenant's bill (and confirming statements and invoices) therefor. If Landlord
contests the existence of a breach as aforesaid, and the contest is revolved in
Tenant's favor, then Tenant shall have the right to cure the breach if, within
ten (10) days thereafter, Landlord fails to commence and diligently pursue the
cure to completion.


                                  ARTICLE 22

                                  DEFINITIONS

Accordingly, if (a) title to the Land and Building or to the lessee's interest
under such a lease is transferred, or (b) a lease of the Building, or of the
Land and Building is entered into by Landlord or any successor to Landlord, then
upon notification to Tenant of the transfer or lease the transferor (whether it
is Landlord or any successor of Landlord) shall be freed and relieved of all
obligations of Landlord under this Lease with respect to any period subsequent
to the transfer. It shall be deemed and construed to be a covenant running with
the land without further agreement between the parties or their successors in
interest, or between the parties and the transferee of title to the Land and
Building or any such lessee's interest in a lease of either or both of the Land
and the Building or the lessee of the Building or of the Land and Building, that

record on the date of this Lease.

and no making of any inspection or granting of any consent or approval by
Landlord shall constitute (a) a release of Tenant from any obligation that it
has under this Lease, or (b) a warranty, guarantee, or assurance by Landlord
regarding (i) the subject of the inspection, consent or approval, or of results
thereof, or (ii) the conformity with law or with this Lease of the subject
matter of the inspection, approval or consent. Tenant shall have no right to
rely upon any such inspection, approval or consent as an assurance of conformity
with any requirement imposed on Tenant in performing its obligations under this
Lease.

harmless and indemnify the other from and against any and all claims, losses,
costs, expenses (including reasonable attorneys' fees) and liability for any
compensation, commissions or charges claimed by any broker or agent, other than
the brokers set forth in this Section 24.1 with respect to this Lease or the

                      CERTIFICATE OF TENANT AND LANDLORD

        25.1  Each party will, at any time and from time to time, as requested
by the other party, upon not less than ten days' prior notice, execute and
deliver to the other a statement certifying that this Lease is unmodified and in
full force and effect (or if there have been modifications, that this Lease is
in full force and effect as modified and stating the modifications), certifying
the dates to which the Annual Net Rent and the Additional Rent have been paid,
and stating whether, to the best knowledge of the signer, the other party is in
default in performance of any of its obligations under this Lease, and, if so,
specifying each such default, it being intended that any such statement
delivered pursuant hereto may be relied upon by others with whom the party
requesting such certificate may be dealing.

        25.2  Except for the first month's rent hereunder, Tenant will pay no
rent under this Lease more than 30 days in advance of its due date, if so
restricted by any existing or future ground or underlying lease or mortgage to
which this Lease is subordinated or by an assignment of this Lease to the ground
or underlying lessor or the holder of such mortgage, and Tenant will not
exercise any right to terminate this Lease or to remedy any default by Landlord
and deduct the cost thereof from the Total Rents until Tenant has given notice
of that default to the ground or underlying lessor and to the holder of any
mortgage on the fee or the ground or underlying lease who has furnished such
lessor's or holder's last address to Tenant, and until a reasonable period for
remedying the default has elapsed following the giving of such notices, during
which time such lessor or holder shall have the right, but shall not be
obligated, to remedy the default. Tenant shall not exercise any right pursuant
to this Section 25.2 if the holder of any mortgage or such lessor commences to
cure the default within a reasonable time and diligently prosecutes the cure.

                    LEGAL PROCEEDINGS; WAIVER OF JURY TRIAL

        26.1  Landlord and Tenant each waives trial by jury in any action
brought by either of the parties hereto against the other on any matters
whatsoever arising out of or in any way connected with this Lease, the
relationship of

                                       43
<PAGE>

Landlord and Tenant, Tenant's use or occupancy of the Demised Premises, and any
other claims (except claims for personal injury or property damage), and any
emergency statutory or any other statutory remedy. If Landlord commences any
summary proceeding for nonpayment of rent, then Tenant will not interpose any
non-compulsory counterclaim in any such action. Tenant, for itself and for all
persons claiming through or under it, hereby expressly waives any and all rights
by any present or future law to redeem the Demised Premises, or to any new trial
in any action or ejection under any provisions of law, after reentry thereupon,
or upon any part thereof, by Landlord, or after any warrant to dispossess or
judgment in ejection.


                                  ARTICLE 27

                             SURRENDER OF PREMISES

        27.1  Upon the expiration or other termination of the Term, Tenant shall
(a) quit and surrender to Landlord the Demised Premises, broom clean, in good
order and condition, ordinary wear and tear and damage by casualty excepted, (b)
remove all of its property as herein provided, and (c) remove Alterations, to
the extent required under Section 10.5 hereof. Tenant's obligation to observe or
perform this covenant shall survive the Termination.

        27.2  If Tenant fails to surrender possession of the Demised Premises
upon Termination, then Landlord may elect, by notice to Tenant, to treat Tenant
as a holdover upon a month to month basis at a rent equal to the greater of (a)
the then current fair market rental value of the Demised Premises, or (b) 1 3/4
times the Annual Net Rent and Additional Rent per month which Tenant was
required to pay during (or in the case of Additional Rent, on account of or
attributable to) the calendar month immediately prior to Termination. If the
Demised Premises are not surrendered upon Termination, then Tenant shall
indemnify and hold harmless Landlord against and from any loss, costs, liability
or expenses (including attorneys' fees) resulting from the failure to surrender,
including any claims made by any succeeding lessee founded upon such delay.
Nothing contained in this Section 27.2 shall be deemed to give to Tenant any
right to fail to surrender possession or to hold over, and the provisions of
this Section 27.2 shall not constitute an offer to rent on a month-to-month
basis or at the rent set forth above.

        27.3  If the last day of the Term falls on a Sunday or a legal holiday
then this Lease shall end on the immediately preceding Business Day. If Tenant
has removed all of its personnel and all or substantially all of its property
from the Demised Premises or any full floor constituting a part of the Demised
Premises at any time during the last month of the Term, then upon that removal
Landlord may, with Tenant's prior approval, which approval shall not be
unreasonably withheld, conditioned or delayed, enter and alter, renovate and
redecorate the Demised Premises or any vacated full floor, without elimination,
diminution or abatement of rent, or incurring any liability to Tenant, and such
acts by Landlord shall have no effect upon this Lease, except that Tenant shall
have no obligations relating to the condition or use of the portion of the
Demised Premises that Landlord enters, nor any liability to Landlord regarding
anything that occurs within the portion of the Demised Premises that Landlord
enters, on or after the date that Landlord enters such portion of the Demised
Premises.

                             RULES AND REGULATIONS

        28.1  Tenant and Tenant's servants, employees, agents, visitors and
licensees shall observe faithfully and comply strictly with the Rules and
Regulations set forth in Schedule G attached hereto and made part hereof and
                         ----------
such other and further reasonable Rules and Regulations as Landlord or
Landlord's agents may from time to time adopt (together, the "Rules and
Regulations"). If there is any conflict or inconsistency between the provisions
of this Lease and any of the Rules and Regulations, the provisions of this Lease
shall control. Reasonable written notice of any change in the Rules and

                                       44
<PAGE>

Regulations shall be given to Tenant.  The Rules and Regulations shall be
applied and enforced uniformly against all tenants in the Building, except to
the extent that uniform applicability and enforcement is not appropriate,
provided that Landlord shall not be liable to Tenant for any violation of the
Rules and Regulations by any other tenant or its servants, employees, agents,
visitors or licensees, except to the extent caused by Landlord's gross
negligence or willful misconduct.

        Nothing in this Lease shall be construed to impose upon Landlord any
duty or obligation to enforce the provisions of any other lease against any
other tenant of the Building, and Landlord shall not be liable to Tenant for
violation of the same by any other tenant, its servants, employees, agents,
visitors or licensees.


                                  ARTICLE 29

                            CONSENTS AND APPROVALS

        29.1  Wherever in this Lease Landlord's consent or approval is required,
such consent or approval shall only be effective if in writing. If Landlord
delays or refuses to give such consent or approval, then Tenant shall not be
entitled to make any claim for money damages (nor shall Tenant claim any money
damages by way of setoff, counterclaim or defense) based upon any claim or
assertion by Tenant that Landlord unreasonably withheld or unreasonably delayed
its consent or approval, unless Tenant can establish that a consent or approval
was withheld capriciously and in bad faith. Tenant's sole remedy, except in the
case of capriciousness and bad faith, shall be an action or proceeding for
specific performance, to enforce Landlord's obligation, if any, to give such
consent or approval, or for a declaratory judgment.


                                  ARTICLE 30

                                    NOTICES

        30.1  Any notice or demand, consent, request, approval or disapproval,
or statement (any of which is referred to as a "Notice") required to be given
under this Lease, or by any Law shall be in writing. Unless otherwise required
by Law, the Notice shall be deemed to have been served and given when the Notice
is hand delivered or mailed enclosed in a securely sealed postpaid wrapper by
registered or certified mail or by nationally recognized, overnight courier
providing evidence of receipt sent priority overnight to Landlord or Tenant, as
the case may be, at the address of such party set forth on page 1 of this Lease.
Notices to Landlord shall be also addressed to the attention of the building
manager at the Property and to Landlord's corporate offices at 24 Richmond Hill
Avenue, Stamford, CT 06901, to the attention of President, Real Estate Group,
with a copy of all such notices to Landlord to be sent to Rogin, Nassau, Caplan,
Lassman & Hirtle, LLC, CityPlace 1, 22nd Floor, Hartford, CT 06103 Attn: Peter
S. Sorokin, Esq. After Tenant occupies the Demised Premises, the address of
Tenant for Notices shall be the Building. Copies of notice to Tenant shall be
sent to Robinson & Cole LLP. Financial Centre, 695 East Main Street, Stamford,
CT 06904-2305 Attn: Frank L. Baker, Esq., and to Cushman & Wakefield of
Connecticut, Inc., Four Stamford Plaza, 8th Floor, Stamford, CT 06902 Attn:
Kevin M. Foley. Either party, by a Notice, may designate a different address or
addresses for Notices.

        30.2  Either Landlord or Tenant may, from time to time, request in
writing that the other party serve a copy of any Notice on one person designated
in the request, in addition to Landlord or Tenant, as the case may be, service
to be effected as provided in Section 30.1.


                                  ARTICLE 31

<PAGE>

                                   NO WAIVER

        31.1  No agreement to accept the surrender of this Lease shall be valid
unless in writing signed by Landlord. No employee of Landlord or of Landlord's
agents shall have any power to accept the keys to the Demised Premises before
Termination. The delivery of keys to any employee of Landlord or of Landlord's
agents shall not operate as a Termination or a surrender of the Demised
Premises. If Tenant desires to have Landlord sublet all or any portion of the
Demised Premises for Tenant's account, then Landlord or Landlord's agents are
authorized to receive the keys for that portion of the Demised Premises intended
to be sublet without releasing Tenant from any of its obligations under this
Lease, and Tenant releases Landlord from any liability for loss or damage to any
of Tenant's property in connection therewith.

        31.2  Either party's failure to seek redress for violation of, or to
insist upon the strict performance of, this Lease, or any of the Rules and
Regulations, shall not prevent a subsequent act by the breaching party, which
would originally have constituted a violation or failure strictly to perform by
Tenant, from having all the force and effect of an original violation.
Landlord's failure to enforce any of the Rules and Regulations against Tenant or
any other tenant in the Building shall not be deemed a waiver of any of the
Rules and Regulations. The receipt by Landlord and/or payment by Tenant of any
of the Total Rents with knowledge of the breach of this Lease by the other party
shall not be deemed to be a waiver of that breach. No provision of this Lease
shall be deemed to have been waived , unless such waiver is in writing signed by
the waiving party.

        31.3  No payment by Tenant or receipt by Landlord at any time of any
amount on account of Annual Net Rent or Additional Rent that is less than the
amount of either that is due at that time shall be deemed to be other than on
account of such unpaid amounts of the Total Rents as Landlord may determine in
accordance with Section 36.8. No endorsement by Landlord of a check for or
acceptance by Landlord of any payment on account of the Total Rents shall be
deemed to be an accord and satisfaction, and Landlord may accept any such check
or payment in a lesser amount than is due without prejudice to Landlord's right
to recover the balance of the Total Rents and to pursue any other remedy under
this Lease. The receipt and retention by Landlord of payments on account of the
Total Rents from any person other than Tenant shall not be deemed to be a waiver
of any provision of this Lease to be performed by Tenant or the acceptance of
such person as a lessee or the release of Tenant from its further performance of
this Lease.

        31.4  This Lease contains the entire agreement between the parties, and
any agreement hereafter made shall be ineffective to change, modify, discharge
or effect an abandonment of it, in whole or in part, unless such agreement is in
writing and signed by the party against whom enforcement of the change,
modification, discharge or abandonment is sought.

        33.1  If, by reason of (a) strike, (b) labor troubles, (c) governmental
preemption in connection with a national emergency, (d) any rule, order or
regulation of any governmental agency, (e) conditions of supply or demand which
are affected by war or other national, state or municipal emergency, or any
other cause (f) severe weather conditions, (g)

industry-wide inability to obtain materials or services; (h) fire or other
casualty, earthquake, floods or other similar significant acts of god; (i)
explosion, sabotage or accident; or (j) any cause beyond Landlord's reasonable
control, any of the foregoing being referred to herein as "Force Majeure" or a
"Force Majeure Event" Landlord is unable to perform or is delayed in performing
any of its obligations under this Lease or is unable to supply or is delayed in
supplying any service which Landlord is obligated to supply, then Landlord shall
have no liability in connection with that inability and this Lease and Tenant's
obligation to perform all of Tenant's obligations under this Lease shall in no
way be affected, impaired or excused as long as the conditions in (a) through
(j) above apply. No condition that can be cured with the payment of a
commercially reasonable amount of money shall be deemed to be a Force Majeure
Event. Tenant shall similarly be excused for delay in the performance of
obligations hereunder provided that nothing contained in this Section or
elsewhere in this Lease shall be deemed to excuse or permit any delay in the
payment of any sums of money required hereunder. No reliance by Landlord or
Tenant upon this Section shall limit or restrict in any way the other party's
right of self-help as provided in this Lease. Neither Landlord nor Tenant shall
be entitled to rely upon this Section unless it shall advise the other party in
writing of the existence of Force Majeure preventing the performance of an
obligation within ten (10) business days after the commencement of the Force
Majeure.


                                  ARTICLE 34

                        NO REPRESENTATIONS BY LANDLORD

        34.1  Except as otherwise specifically provided in this Lease, Landlord
and Landlord's agents have made no representations or promises with respect to
the Building or Demised Premises and Tenant acknowledges that it has not relied
on any representations or promises except as set forth in this Lease.

       34.2   Notwithstanding anything to the contrary contained in the
Lease, Landlord hereby represents to Tenant as follows:

              (a) Landlord is the lessee of the Land and Building under a lease
with Louis Dreyfus Corporation, which is the sole fee simple owner of the Land;

              (b) The Building is not subjected to control or tax by any
improvement, utility, beautification or similar private district or association;
and

              (c) Office uses are permitted uses under the zoning ordinances of
the Town of Wilton that are applicable to the Building.

                                  ARBITRATION

        35.1  In any case specified in this Lease in which resort to arbitration
is required, such arbitration shall be held in Connecticut in accordance with
the Commercial Arbitration Rules of the American Arbitration Association and the
provisions of this Lease. The decision and award of the arbitrators shall be in
writing, shall be final and conclusive on the parties, and counterpart copies
thereof shall be delivered to each of the parties. In rendering the decision and
awards, the arbitrators shall not add to, subtract from or otherwise modify the
provisions of this Lease. Judgment may be had on the decision and award of the
arbitrators so rendered in any court of competent jurisdiction. Each party shall
be responsible for

                                       47
<PAGE>

paying all of its own costs (including legal fees and disbursements) relating to
the arbitration.

                                 MISCELLANEOUS

        36.1  Irrespective of the place of execution or performance, this Lease
shall be governed by and construed in accordance with the laws of the State of
Connecticut.

        36.2  This Lease shall be construed without regard to any presumption or
other rule requiring construction against the party causing this Lease to be
drafted.

        36.3  Except as otherwise expressly provided in this Lease, each
provision of this Lease to be performed by Tenant or Landlord shall be deemed
and construed as a separate and independent covenant of Tenant or Landlord, not
dependent on any other provisions of this Lease.

        36.4  All terms and words used in this Lease, regardless of the number
or gender in which they are used, shall be deemed to include any other number
and any other gender as the context may require.

        36.5  Time shall be of the essence with respect to the exercise of any
option granted under this Lease.

        36.6  Except as otherwise provided in this Lease, whenever payment of
interest is required by the terms hereof, it shall be at the Interest Rate.

        36.7  Tenant shall not record this Lease, or a memorandum of this Lease,
at any time. A violation of this provision shall be deemed a default under this
Lease.

        36.8  If Tenant is in arrears in payment of any amount of the Total
Rents, Tenant waives Tenant's right, if any, to designate the items against
which any payments made by Tenant are to be credited, and Landlord may apply any
payments made by Tenant to any items payable by Tenant that Landlord it sees
fit, irrespective of and notwithstanding any designation or request by Tenant as
to the items against which any such payments shall be credited.

        36.9  The provisions of this Lease shall be binding upon and inure to
the benefit of Landlord, Tenant and their respective successors and assigns,
except that no assignment or subletting in violation of the provisions of
Article 17 shall operate to vest any rights in any successor assignee or
subtenant.

        36.10 This Lease shall not be binding upon Landlord unless and until it
is signed by both parties hereto and a signed copy thereof is delivered by
Landlord to Tenant.

                               SECURITY DEPOSIT

        37.1  Tenant shall deposit with Landlord the sum of Two Million Four
Hundred Eighty-one Thousand Three Hundred Twenty-five and 00/100 Dollars
($2,481,325.00) (the "Security Deposit"), and which Landlord shall be

                                       48
<PAGE>

entitled to continue to hold as security for the faithful performance and
observance by Tenant of the terms, provisions, and conditions of this Lease. One
Million Two Hundred Forty Thousand Six Hundred Sixty-two Dollars and 50/100
($1,240,662.50) of the Security Deposit shall be deposited with Landlord upon
the execution of this Lease, and $1,240,662.50 of the Security Deposit shall be
deposited with Landlord on or before January 10, 2001. Provided that no default
by Tenant under this Lease, beyond applicable notice and cure periods, has
theretofore occurred, the amount of the Security Deposit shall be reduced, on
each anniversary of the Rent Commencement Date starting with the sixth (6th)
such anniversary, by $206,777.08. In the event that Tenant defaults, after the
expiration of any applicable notice and/or cure periods, in respect to any of
the terms, provisions, and conditions of this Lease, including, without
limitation, the payment of Annual Net Rent and Additional Rent, Landlord may
use, apply, or retain the whole or any part of the Security Deposit to the
extent required for the payment of any Annual Net Rent, Additional Rent, or any
other sum as to which Tenant is in default or for any sum which Landlord may
expend or may be required to expend by reason of Tenant's default in respect of
any of the terms, covenants and conditions of this Lease, including without
limitation, any damages or deficiency in reletting the Demised Premises accrued
before or after any summary proceedings or other re-entry be Landlord. Landlord
shall provide Tenant with a statement that details the items that Landlord is
applying the Security Deposit against, within thirty (30) days after any such
application.

        37.2  Notwithstanding Section 37.1 above, in lieu of a cash Security
Deposit, Tenant may obtain and deliver to Landlord an unconditional, irrevocable
letter of credit, in the then required amount of the Security Deposit (the
"Letter of Credit"). Tenant shall be responsible, at its sole cost, for paying
any and all letter of credit or other fees due to the issuer of the Letter of
Credit. Such Letter of Credit shall be provided by a bank that is reasonably
acceptable to Landlord, shall permit partial draws, shall be assignable by
Landlord (without any cost to Landlord) and shall be for an initial term of one
year and be automatically renewable (i.e. "Evergreen") for successive one year
periods (unless Landlord receives notice of non-renewal at least ten (10) days
prior to the expiration of the Letter of Credit), so that it remains outstanding
for as long as the Lease is in effect, and shall otherwise be in a form that is
reasonably acceptable to Landlord. The Letter of Credit must be able to be drawn
upon in New York City or elsewhere if approved by Landlord. In the event of any
default by Tenant under this Lease, Landlord shall be entitled to draw upon the
Letter of Credit to the extent of, and to reimburse Landlord for, any and all
damages owed to Landlord by Tenant as a result of such default. If at any time
the Letter of Credit is due to expire or Landlord receives notice that it will
expire and Landlord has not received written evidence of the renewal thereof at
least ten (10) days before such expiration, Landlord may draw upon the Letter of
Credit for the full amount thereof in which event the proceeds shall become a
cash Security Deposit subject to the provisions set forth above. Tenant shall,
if requested by Landlord, have the Letter of Credit issued directly to Lessor's
first mortgagee.

        37.3  In the event that Tenant shall fully and faithfully comply with
all of the terms, provisions, covenants and conditions of this Lease, the
Security Deposit or Letter of Credit, except as same may have been applied by
Landlord in accordance with this Lease, shall be returned to Tenant within
thirty (30) days after the Expiration Date or such earlier termination date of
this Lease and after Tenant has delivered entire possession of the Demised
Premises to Landlord in accordance with all of the terms and provisions of this
Lease.

        37.4  Tenant agrees that in the event Landlord draws upon the Letter of
Credit or applies any portion of the Security Deposit in accordance with the
provisions of this Lease, Tenant will immediately upon demand of Landlord
replace the drawn upon Letter of Credit with a new Letter of Credit in the full
amount of the drawn upon Letter of Credit, or reimburse or pay Landlord for the
amount of the Security Deposit so applied so that the amount constituting the
Security Deposit or Letter of Credit during the term of this Lease shall always
be equal to the then required amount of the Security Deposit.

        37.5  In the event of a sale or leasing of the Building, or of the
portion of the Building in which the Demised Premises are located, Landlord
shall have the right to transfer the Letter of Credit or Security Deposit to the
vendee or

                                       49
<PAGE>

lessee and provided that such transferee assumes this Lease and Landlord's
obligations hereunder that accrue on and after the date of the transfer, and
Tenant is provided with notice of such assumption, Landlord shall thereupon be
released by Tenant from all liability for the return of the Letter of Credit or
Security Deposit and it is agreed that the provisions hereof shall apply to
event transfer or assignment made of the Letter of Credit or Security Deposit to
a new Landlord.

        37.6  Tenant further agrees that it will not assign or encumber or
attempt to assign or encumber the moneys constituting the Letter of Credit or
any moneys constituting the Security Deposit, and that neither Landlord nor is
successors or assigns shall be bound by any such assignment, encumbrance or
attempted assignment or encumbrance.

                              EXTENSIONS OF TERM

       38.1   (a)  Tenant shall have the right to extend the term of this Lease
for one (1) five (5) year term, such extension term to commence on the date
immediately succeeding the Expiration Date and to end on the last day of the
month in which occurs the fifth (5th) anniversary of the Expiration Date (the
"Extension Term"), provided that:

                   (i)   Tenant shall give Landlord notice (hereinafter called
an "Extension Notice") of its election to extend the term of this Lease no later
than fifteen (15) months prior to the Expiration Date;

                   (ii)  Tenant is not in default of any obligations under this
Lease (which, with respect to non-monetary defaults, shall be beyond applicable
notice and cure periods, if Tenant is diligently attempting to cure the default)
as of the time of the giving of the Extension Notice and the commencement date
of the Extension Term; and

                   (iii) Tenant shall be in actual occupancy of fifty (50%)
percent or more of the Rentable Area of the Demised Premises as of the time of
the giving of the Extension Notice and on the commencement date of the Extension
Term, provided that no portion of the Demised Premises that is not occupied by
Tenant may be occupied by more than two (2) subtenants.

        38.2  The Annual Net Rent for the Premises for the Extension Term shall
be an amount equal to the greater of (a) the annual fair market rental value of
the Premises (the "Fair Market Rent") on the date that is eighteen (18) months
prior to the commencement date of the Extension Term, and (b) the Annual Net
Rent payable by Tenant on the Expiration Date or the expiration date of the
First Renewal Term, as the case may be (the greater value of (a) and (b) being
hereinafter referred to as the "Rental Value"). In determining the Fair Market
Rent hereunder, the arbitrators shall consider all then relevant factors.
Landlord shall notify Tenant of its determination of the Fair Market Rent for
the Premises (the "Rent Notice") within thirty (30) days after receipt of the
Extension Notice.

        38.3  In the event Tenant gives the Extension Notice in accordance with
the provisions of Section 40.1 hereof and Tenant disagrees with the
determination of Fair Market Rent set forth in the Rent Notice, Tenant shall
notify Landlord of such fact in writing within fifteen (15) days after receipt
of a Rent Notice, and Landlord and Tenant will, within thirty (30) days after
Lessee's receipt of such Rent Notice, use reasonable efforts to mutually agree
on the Fair Market Rent for the Premises. If Landlord and Tenant are unable to
agree on the Fair Market Rent within such thirty (30) day period as aforesaid
then either Landlord or Tenant may initiate the arbitration process provided for
herein by giving notice to that effect to the other, and the party so initiating
the arbitration process (such party hereinafter referred to as the "Initiating
Party") shall specify in such notice the name and address of the person
designated to act as an arbitrator on its behalf. Within fifteen (15)

                                       50
<PAGE>

Business Days after the designation of an arbitrator, the other party
(hereinafter referred to as the "Other Party") shall give notice to the
Initiating Party specifying the name and address of the person designated to act
as an arbitrator on its behalf. If the Other Party fails to notify the
Initiating Party of the appointment of its arbitrator within the time above
specified, then the determination of the arbitrator designated by the Initiating
Party shall be conclusive and binding. The two arbitrators so chosen shall meet
within ten (10) Business Days after the second arbitrator is appointed and if,
within ten (10) Business Days after the second arbitrator is appointed, the two
arbitrators shall not agree, they shall together appoint a third arbitrator. In
the event of their being unable to agree upon such appointment within ten (10)
Business Days after the appointment of the second arbitrator, the third
arbitrator shall be selected by the parties themselves if they can agree thereon
within a further period of ten (10) Business Days. If the parties do not so
agree, then either party, on behalf of both and on notice to the other, may
request such appointment by the American Arbitration Association (or
organization successor thereto) in accordance with its rules then prevailing or
if the American Arbitration Association (or such successor organization) shall
fail to appoint said third arbitrator within ten (10) Business Days after such
request is made, then either party may apply, on notice to the other, to the
Superior Court for the judicial district of Stamford-Norwalk, Connecticut (or
any other court having jurisdiction and exercising functions similar to those
now exercised by said Court) for the appointment of such third arbitrator.

               (a) Each party shall pay the fees and expenses of the one of the
two original arbitrators appointed by or for such party, and the fees and
expenses of the third arbitrator and all other expenses (not including the
reasonable attorneys' fees, reasonable witness fees and similar expenses of the
parties, which shall be borne separately by each of the parties) of the
arbitration shall be borne by the parties equally.

               (b) Except as otherwise expressly set forth, the majority of the
arbitrators shall determine the Fair Market Rent of the Premises and render a
written report of their determination to both Landlord and Tenant within twenty
(20) Business Days of the appointment of the first two arbitrators or thirty
(30) days from the appointment of the third arbitrator if such third arbitrator
is appointed pursuant to this Section 38.3.

               (c) Each of the arbitrators selected as herein provided shall
have at least ten (10) years experience in the leasing and renting of office
space in first-class office buildings or parks in Fairfield County, Connecticut.

               (d) In the event Landlord or Tenant initiates the arbitration
process pursuant to this Section 38.3 and as of the commencement date of the
Extension Term the amount of the Fair Market Rent has not been determined,
Tenant shall pay the amount that Tenant was required to pay in the month
immediately preceding such commencement date until such determination has been
made and when such determination has been made, it will be retroactive as of the
commencement date of the Extension Term and any deficiency shall be paid by
Tenant to Landlord within thirty (30) days after the date of such determination
with interest thereon at the Prime Rate and any overpayment shall be credited by
Landlord to Tenant against the next installment(s) of Annual Net Rent and
Additional Rent payable hereunder.

               (e) If Landlord notifies Tenant that the Rental Value for the
Extension Term shall be the amount set forth in clause (b) of Section 38.2
hereof, then the provisions of Section 38.3 hereof shall be inapplicable to the
Extension Term and shall have no force or effect for the Extension Term.

        38.4  Except as provided in Section 38.2 hereof, Tenant's occupancy of
the Premises during the Extension Term shall be on the same terms and conditions
as are in effect immediately prior to the expiration of the initial Term;
provided, however, that Landlord shall not be required to renovate the Demised
Premises or provide any allowance therefor, and after the Extension Term Tenant
shall have no further right to extend the term of this Lease pursuant to this
Article 38.

       38.5   If Tenant does not send the Extension Notice pursuant to the
provisions of Section 38.1 hereof, this

                                       51
<PAGE>

Article 38 shall have no force and effect and shall be deemed deleted from this
Lease.

       38.6       If this Lease is renewed for the Extension Term then in such
instance Landlord or Tenant can request the other party hereto to execute an
instrument in form for recording setting forth the exercise of Tenant's right to
extend the term of this Lease and the last day of the Extension Term.

       38.7       If Tenant exercises its right to extend the term of this Lease
for the Extension Term  pursuant to this Article 40, the phrases "the term of
this Lease" of "the term hereof" as used in this Lease, shall be construed to
include, when practicable, the Extension Term.


                                  ARTICLE 39

                                TEMPORARY SPACE

       39.1       Landlord shall, if requested by Tenant, cooperate with Tenant
(from the date of such request through September 1, 2000) to endeavor to locate
approximately 3,000 square feet of space, for temporary occupancy by Tenant as
of September 1, 2000, in buildings, other than the Building, that are within one
(1) mile of the Building.  If successful, Tenant shall be responsible, at its
cost, for negotiating a lease for the temporary space, and for all rent and
other costs associates with such tenancy.  Whether successful or not, Tenant
shall reimburse Landlord, within fifteen (15) days after receipt of invoices
from Landlord, for all costs incurred by Landlord in connection with the search
for such temporary space.  The failure to locate any such temporary space shall
not result in any liability by Landlord to Tenant, nor shall any such failure in
any way affect Tenant's obligations under this Lease.


                                  ARTICLE 40

                             RIGHT OF FIRST OFFER

       40.1       (a) Provided that (i) Tenant is not in default under this
Lease (which, with respect to non-monetary defaults, shall be beyond applicable
notice and cure periods, if Tenant is diligently attempting to cure the
default), (ii) this Lease is in full force and effect, and (iii) Tenant has not
assigned this Lease or is not then subletting any of the Demised Premises (other
than any sublease of the Initial Sublease Area), Tenant shall have a right of
first offer during the Term (including the Extension Term, if exercised) (the
"Notice Period") with respect to the leasing of any space in the Building
("Potential Expansion Space"), subject to rights if any then existing tenants
thereto (which shall include Landlord's right to allow any existing tenant to
remain in its space after the expiration of its term, whether or not such tenant
has a renewal option in its lease), in accordance with the following terms and
conditions.

                  (b) Landlord shall, within the Notice Period, notify Tenant
(an "Expansion Offer Notice") as to any portion of the Potential Expansion Space
that Landlord proposes to lease to third parties (the "Expansion Space"). Such
notice shall identify the Expansion Space and shall set forth Landlord's
determination of the Fair Market Rent for such space, and Tenant shall have the
right to lease the Expansion Space, on all of the terms and conditions contained
in this Lease, except that: (i) Annual Net Rent therefor shall be the greater of
the Fair Market Rent (which shall be calculated considering that Tenant may
receive up to ninety (90) days of free rent after the Expansion Inclusion Date
before the Expansion Space Rent Commencement Date occurs) or the amount of
Annual Net Rent per square foot of Rentable Area that is payable under this
Lease, as the same shall increase pursuant to Section 1.1 hereof, and (ii)
Landlord must be satisfied with Tenant's

                                       52
<PAGE>

creditworthiness, and to the extent that Landlord is not satisfied, Tenant must
post a security deposit in an amount that is acceptable to Landlord. In
connection therewith, if Tenant's creditworthiness at the time is not materially
diminished from Tenant's creditworthiness as of the date of this Lease, and
there is a tenant improvement allowance being provided to Tenant and a brokerage
commission payable by Landlord in connection with such expansion, then the
security deposit shall be in the amount of such allowance and commission. In all
other circumstances, then the security deposit for such expansion shall be
determined by Landlord in its business judgment, exercised in good faith. In
order to exercise the right of first offer contained in this Article 40, Tenant
must notify Landlord no later than fifteen (15) Business Days following delivery
of Landlord's notice to Tenant. Tenant may only exercise its right of first
offer as to the entire Expansion Space identified in Landlord's notice to
Tenant, and in connection therewith, if all of building B and/or building C are
available, Landlord may require that Tenant lease all of building B and/or all
of building C only. If Tenant fails to notify Landlord of its interest within
the time period specified herein, or if Landlord and Tenant cannot agree on the
amount of security deposit for the Expansion Space within fifteen (15) business
days after Tenant's exercise of its right of first offer, then Landlord's
obligations under this Article 40 shall be discharged with respect to the
Expansion Space in question and Tenant shall have no further rights under this
Article 40 with respect to the Expansion Space in question.

       40.2    (a)   If Tenant timely exercises its right of first offer under
this Article 40, then the Expansion Space shall be deemed added to and included
in the Demised Premises and all of the terms and conditions of this Lease, as
modified by this Article 40, shall apply to the Expansion Space for the balance
of the Term, as of the date of Tenant's exercise notice (the "Expansion Space
Inclusion Date"), except that Annual Net Rent shall not be payable with respect
thereto, and Tenant's Share shall not be increased to reflect the Rentable Area
therein, until the Expansion Space Rent Commencement Date.

               (b)   The "Expansion Space Rent Commencement Date" shall be the
earlier to occur of (i) the date on which Tenant first conducts business in any
portion of the Expansion Space, or (ii) ninety (90) days after the Expansion
Space Inclusion Date. As of the Expansion Space Rent Commencement Date:

               (i)   Annual Net Rent payable hereunder as set forth in Section
1.1 hereof shall be increased by the amount of Annual Net Rent payable with
respect thereto pursuant to Section 40.1(b) above.

               (ii)  Tenant's Share shall be increased to include the Rentable
Area of the Expansion Space in the Rentable Area of the Demised Premises.

               (c)   If the Fair Market Rent provided by Landlord in the
Expansion Offer Notice is greater than the amount of annual Net Rent per square
foot of Rentable Area under this Lease, as the same shall increase pursuant to
Section 1.1 hereof, and if Landlord and Tenant are unable to agree on the Fair
Market Rent with respect to the Expansion Space in question, then such Fair
Market Rent shall be determined pursuant to the procedures set forth in Section
38.3 hereof. The determination of the arbitrators with respect to Fair Market
Rent shall be conclusive and binding on the parties hereto. In the event that,
as of the Expansion Space Rent Commencement Date, the amount of the Fair Market
Rent has not been determined, Tenant shall pay an amount equal to the amount of
Annual Net Rent per square foot of Rentable Area of the Expansion Space that is
payable under this Lease, as the same shall increase pursuant to Section 1.1
hereof, until such determination has been made and when such determination has
been made, it will be retroactive as of the Expansion Space Rent Commencement
Date and any deficiency shall be paid by Tenant to Landlord within thirty (30)
days after the date of such determination with interest thereon at the Prime
Rate.

               (d)   Upon the determination of the Annual Net Rent for the
Expansion Space, Tenant shall execute an amendment to this Lease with Landlord
with respect to the Expansion Space to reflect the terms and conditions

                                       53

applicable thereto.

       40.3    Tenant agrees to accept the Expansion Space pursuant to this
Article 40 in its then existing conditions and state of repair. Tenant
understands and agrees that, except for the Tenant Improvement Allowance
provided under Section 40.1(b) hereof, Landlord shall perform no work and incur
no cost of expense in connection with the preparation of such space for Tenant's
occupancy.

       40.4    Tenant's rights under this Article 40 shall terminate as to any
specific Expansion Space upon Tenant's having failed to exercise its election to
lease the Expansion Space, or if Landlord and Tenant cannot agree on a security
deposit, pursuant to Section 40.1 hereof and Landlord shall thereafter be
entitled to lease such Expansion Space to others upon such terms and conditions
as Landlord, in its sole discretion, may desire, provided that if Tenant fails
to exercise its election to lease an Expansion Space, and Landlord does not
enter into a lease for any portion of the Expansion Space in question within six
(6) months thereafter (which six (6) month period shall be extended to the
extent that Landlord is actively negotiating with one or more tenants for such
space), then Landlord shall reoffer such portion of the Expansion Space to
Tenant under this Article 40.

                                  ARTICLE 44

                          NEW PROVIDER INSTALLATIONS

       44.1    In the event the Tenant wishes at any time to utilize the
services of a telephone or telecommunications provider (a "TSP") whose equipment
is not then servicing the Building, no such TSP shall be permitted to install
its lines or other equipment within the Building without first securing the
prior written approval of the Landlord, which approval shall not be unreasonably
withheld.  Landlord's approval shall not be deemed any kind of warranty or
representation by Landlord, including, without limitation, any warranty or
representation as to the suitability, competence, or financial strength of the
TSP.  Without limitation of the foregoing standard, unless all of the following
conditions are satisfied to Landlord's reasonable satisfaction, it shall be
reasonable for Landlord to refuse to give its approval:  (a) Landlord shall
incur no expense whatsoever with respect to any aspect of the TSP's provisions
of its services, including without limitation, the costs of installation,
materials and services; (b) prior to commencement of any work in or about the
Building by the TSP, the TSP shall supply Landlord with such written
indemnities, insurance, financial statements, and such other items as Landlord
reasonably determines to be necessary to protect its financial interests and the
interests of the Building relating to the proposed activities of the TSP; (c)
the TSP agrees in writing to abide by such rules and regulations, building and
other codes, job site rules and such other requirements as are reasonably
determined by Landlord to be necessary to protect the interest of the Building,
the tenants in the Building, and Landlord, in the same or similar manner as
Landlord has the right to protect itself and the Building with respect to
proposed Alterations as described in this Lease; (d) Landlord reasonably
determines that there is sufficient space in the Building for the placement of
all of the TSP's equipment and materials; (e) Landlord receives from the TSP
such compensation as is reasonably determined by Landlord to compensate it for
space used in the Building for the storage and maintenance of the TSP's
equipment, for the fair market value of a provider's access to the Building, and
the costs which may reasonably be expected to be incurred by Landlord in
conjunction with the TSP's occupancy of and activities within the Building; and
(f) all of the foregoing matters are documented in a written agreement between
Landlord and the TSP, the form and content of which is reasonably satisfactory
to Landlord (a "TSP Agreement").

       44.2    The following provisions shall apply to any approved TSP's
activities in the Building:

               (a) The TSP's equipment (the "Equipment") shall only be installed
in locations approved by Landlord and only in accordance with plans and
specifications that have been approved by Landlord.

               (b) Tenant or the TSP shall pay all reasonable out of pocket
costs and expenses incurred by Landlord in reviewing, approving, and supervising
the installation of the Equipment including, without limitation, architects',
engineers' and contractors' fees and expenses, and attorneys' fees for
Landlord's review and drafting of the TSP Agreement. Tenant and the TSP shall be
solely responsible for the cost of installation, operation, maintenance and
repair of the Equipment and Tenant or the TSP shall keep the Equipment in good
condition and make all necessary or appropriate repairs and replacements thereto
subject to the appropriate provisions of this Lease. Tenant or the TSP shall be
responsible for obtaining any permits and licenses required to install and
operate the Equipment. The rights granted to Tenant shall be utilized by Tenant
in a manner which will not unreasonably disturb the occupancy of the other
tenants, licensees or occupants of the Building or Landlord's or any other
tenant's or occupant's business operations.

               (c) Tenant agrees that the Equipment shall be of a type and
frequency which will not cause interference to any other party or any equipment
of any other party including, without limitation, Landlord, other tenants,
licensees and occupants of the Building for communications or any other
purposes; any other tenants, licensees; or occupants

                                       58
<PAGE>

of the Building; or any equipment utilized in the Building. In the event that
the Equipment causes or is believed to cause any such interference, upon receipt
of notice from Landlord of such interference, Tenant will take all steps
necessary to correct and eliminate the interference. If the interference is not
eliminated immediately after receipt of such notice then, upon request from
Landlord, Tenant immediately cease using the Equipment pending resolution of the
interference.

               (d) The Equipment shall only be utilized by Tenant and the TSP
and only to provide services to the Premises in connection with the operation of
Tenant's normal business in the Premises as more particularly described in this
Lease. The Equipment shall not be utilized for any other purpose or to provide
any services to any other tenants of or space in the Building. The TSP may not,
through Tenant or Tenant's rights under this Article 44, market or provide
services to other tenants of the Building.

               (e) Tenant shall, at Tenant's sole cost and expense and subject
to the provisions of Section 4.1 hereof, obtain any electricity necessary and
sufficient to allow the TSP to utilize the Equipment, in accordance with the
provisions of the TSP Agreement. Upon prior notice, Landlord shall promptly
provide Tenant and the TSP access to the Equipment, at Landlord's sole option,
accompanied by a representative of Landlord, during normal business hours and
during non-business hours if an emergency arises. The TSP shall agree to hold
Landlord, and their officers, directors, employees and agents harmless from and
against any and all damages, liabilities, costs and expenses (including
reasonable attorney's fees) arising directly out of any act or omission at the
Building by the TSP or the TSP's employees or agents. The TSP shall agree, at
its sole costs and expense to carry public liability insurance. The amount of
such insurance for bodily injury and property damage liability shall not be less
than a combined single limits of five million and 00/100 dollars ($5,000,000.00)
for each occurrence and a ten million and 00/100 ($10,000,000.00) aggregate
limit. The TSP shall agree to deliver to Landlord evidence of such insurance.

               (f) Tenant's and the TSP's use of the Equipment and the Equipment
Space shall be subject and subordinate to all of the provisions to this Lease
except as expressly modified by the terms and provisions of this Article 44 and
the TSP Agreement.

               (g) In the event that either Tenant or the TSP, with or without
the knowledge of Tenant, shall default under this Article 44 and the TSP
Agreement by installing, maintaining, repairing, replacing or operating
telecommunications equipment other than the Equipment approved by Landlord or by
providing, through Tenant or Tenant's rights under this Article 44,
telecommunications services to any tenant at the Building or at any other
building utilizing the Equipment or other telecommunications equipment installed
at the Building by Tenant of the TSP, with or without the knowledge of Tenant,
and Tenant shall fail to remedy such default within twenty (20) days after
notice by Landlord to Tenant of such default, Landlord shall have the right to
terminate Tenant's and the TSP's rights under the applicable TSP Agreement by
serving a three (3) days' notice of termination upon Tenant. Upon the
termination of a TSP Agreement or upon the expiration or other termination of
this Lease, if requested by Landlord, Tenant shall remove the Equipment from the
Building and repair all damage caused thereby and otherwise restore the Building
to the condition existing prior to such installation in a good and workable
manner at Tenant's sole cost sand expense and Tenant and TSP shall have no
further rights hereunder. In the event that Tenant fails to remove such
Equipment within fifteen (15) days of Landlord's request thereof, Landlord shall
have the right to remove such Equipment and Tenant shall reimburse Landlord for
the cost of such removal, as Additional Rent.

                                       59

          This Workletter supplements and constitutes a part of the Agreement of
Lease (the "Lease") dated as of May __, 2000 executed concurrently herewith, by
and between WILTON REALTY INVESTORS CORP. as Landlord, and MERCATOR SOFTWARE,
INC. as Tenant, covering certain premises described in the Lease.


     1.   Tenant's Plans and Specifications
          ---------------------------------

          1.1  (a) Tenant will coordinate with Landlord and Landlord's architect
and engineer in the design development of Tenant's Plans. Tenant shall submit to
Landlord for Landlord's approval, complete construction documents, which are
plans and specifications for the layout, improvement and finish of the Demised
Premises, including but not limited to partition plans, floor and wall finish
plans, reflected ceiling plans, power, telephone, communications and data plans,
construction detail sheets and millwork and millwork detail plans, showing the
location of partitions, light fixtures, electrical outlets, telephone and
communications outlets, data outlets, sprinklers, doors, equipment
specifications (including floor loading concentrations such that Landlord can
identify uses which result in a floor loading in excess of a live load of 100
pounds per square foot (80+20) design criteria within the Demised Premises,
cooling requirements and power requirements identifying voltage, amps, phase,
and special plugs and connections), wall finishes, floor coverings, other
special weight, cooling or power requirements and other Tenant Improvements
required by Tenant (collectively, "Tenant's Plans"). Landlord shall have the
absolute right to require that the minimum quality of the construction and
finish of any core area that is within the Demised Premises by Tenant be, at
Tenant's sole cost, in compliance with, or of an overall quality equal to, the
Building standard for such construction and finish, and Landlord agrees to
reasonably consider and approve any requests by Tenant to substitute higher
grade materials or finishes which are consistent with Tenant's decorating plans
in the core area. Tenant shall reimburse Landlord for all reasonable costs and
expenses incurred by Landlord (in-house or third party) in connection with
Landlord's review of Tenant's Plans ("Review Fees"), within thirty (30) days
after receipt of appropriate back up therefor.

               (b) Tenant's Plans shall be submitted to Landlord on or before
May 1, 2001.

               (c) Tenant's Plans shall be prepared by a licensed architect
reasonably acceptable to Landlord (if required by the nature of the
improvements), shall be in a form adequate for Tenant to secure the approval of
governmental authorities with jurisdiction over the approval thereof and shall
be in a form meeting Landlord's reasonable requirements, provided that Tenant
shall use engineers designated by Landlord for any portions of Tenant's Plans
involving or affecting the structure of the Building or Building systems
architects. Tenant's architect shall coordinate with Landlord's architect and
engineer to make all of Tenant's Plans consistent with the plans and
specifications for construction of the Building and the Demised Premises.
Landlord's engineer shall have the right, during the design process, to review
each phase of Tenant's design development and the development of Tenant's Plans,
including all engineering capacity reports, to assure their compliance and
coordination with the mechanical, electrical and structural elements of the
Building.

          1.2  Tenant's Plans shall be subject to Landlord's approval as
follows:

               (a) Within four weeks after Landlord's initial review of Tenant's
Plans (as to items not affected by engineering) or within two weeks after
Landlord's engineering of such Tenant's Plans (as to items affected by
engineering),

<PAGE>

Landlord shall give Tenant notice of all specified materials and methods of
construction required in connection with the Tenant Improvements, the use of
which would violate any applicable codes, rules, laws or regulations.
Notwithstanding the other provisions of this Section 1.2, Landlord shall not be
obligated to ascertain the existence of or notify Tenant of any such violations
of applicable codes, rules laws or regulations and the parties agree that it is
the responsibility of Tenant's architect to assure the compliance by Tenant with
such codes, rules laws and regulations. Tenant shall have ten business days from
the date of each such notice to make reasonable substitutions of such materials
or methods of construction, provided the substitution of such is practical,
taking into consideration the cost thereof.  Such substitutions shall be subject
to Landlord's approval, which approval shall not be unreasonably withheld and
shall be given, or reasons for disapproval given, within ten (10) business days
after receipt thereof. If Landlord's disapproval is based on the fact that the
use of such materials or methods of construction would violate such applicable
codes, rules, laws or regulations, then such disapproval shall be deemed
reasonable.

               (b) If after the approval of the Final Plans (as defined below)
and during procurement of the permit or during the course of construction,
Landlord reasonably determines that the procurement of particular materials or
construction of portions of the Tenant Improvements specified in the Final Plans
will violate any applicable codes, rules, laws or regulations, then Landlord
shall give notice thereof to Tenant, and Tenant shall have ten business days to
either make substitutions of such materials and construction or dispute
Landlord's assertion; any unresolved dispute may be resolved in the manner set
forth in Article 35 of the Lease. Such substitutions must not themselves violate
any applicable codes, rules, laws and regulations.

               (c) If Landlord disapproves Tenant's Plans, or any portion
thereof within the four week or two week periods set forth in Section 1.2(a)
hereof, Landlord shall notify Tenant thereof (within the applicable time period)
and of the revisions which Landlord reasonably requires in order to obtain
Landlord's approval. As promptly as reasonably possible thereafter, Tenant shall
submit to Landlord plans and specifications incorporating the revisions required
by Landlord. Said revisions shall be subject to Landlord's approval. If Landlord
disapproves the revised Tenant's Plans, Landlord shall so notify Tenant thereof
within ten (10) business days of receipt thereof and of the further revisions
Landlord reasonably requires in order to obtain Landlord's approval. The
foregoing process shall be repeated until Landlord finally approves all Tenant's
Plans required for the Tenant Improvements in all of the Premises, so that
Landlord and Tenant have an agreed-upon set of final plans and specifications
for the Tenant Improvements. The final Tenant Plans approved by Landlord are
referred to as the "Final Plans." Approval by Landlord shall not be deemed to be
a representation by Landlord as to the adequacy or correctness of the design of
the Tenant Improvements. Landlord's approval of Tenant's Plans or any revisions
thereto shall not be unreasonably withheld, and in connection therewith Landlord
shall consider whether Tenant's Plans call for a build out that is consistent
with a first class building.

          1.3  All improvements described in the Final Plans shall be called
"Tenant Improvements" and, subject to Section 2 hereof shall be constructed in
the Building at Tenant's sole cost and expense. The Tenant Improvements shall be
constructed by the Tenant Contractor, subject to the provisions of Section 4.1
hereof. All engineering required by Tenant's Plans and performed by Tenant's
engineer shall be at Tenant's expense. Once completed, Tenant shall also be
solely responsible for the design, function and maintenance of all Tenant
Improvements, except as specifically provided otherwise in the Lease.

          1.4  All space planning and interior decorating services such as the
selection of wall paint colors and/or wall covering, fixtures, carpeting and any
or all other decorator selection efforts required by Tenant shall be provided by
Tenant at Tenant's expense.

          1.5  Tenant, or Tenant's representative, shall secure all approvals of
governmental authorities necessary to permit the Tenant Contractor to procure
all permits required by governmental authorities having jurisdiction over such

<PAGE>

approvals and permits for the Tenant Improvements, with Landlord's reasonable
cooperation. Tenant shall cause the Tenant Contractor to commence construction
of the Tenant Improvements in accordance with Section 5.1 hereof upon issuance
of all such necessary permits, assuming satisfaction of the conditions described
in Section 4.1. Tenant shall pay for all permits, plan fees, licenses and other
fees required to construct, install and use the Tenant Improvements.

          1.6  Within 60 days after substantial completion of the Tenant
Improvements, Tenant shall submit to Landlord three (3) sets of "as-built"
plans, incorporating all changes and/or revisions that have been made subsequent
to the submission of the Final Plans specified in Section 1.2 above.

     2.   Allowance
          ---------

          2.1  Tenant shall be credited with an allowance (the "Tenant
Improvement Allowance") of $1,735,800.00. The Tenant Improvement Allowance shall
be used solely for the purchase, installation and construction of the Tenant
Improvements which constitute improvements to the Demised Premises or Building
(including, without limitation, carpeting and modular partitions), and for
architectural and engineering fees incurred by Tenant (including, without
limitation, Coordination Fees), but shall not be used for furniture, furnishings
or equipment. In no event shall more than twenty five percent (25%) of the
Tenant Improvement Allowance be used for architectural or engineering fees. If,
and to the extent, the total cost of the Tenant Improvements in the Demised
Premises and Building plus architectural and engineering fees incurred by Tenant
is less than the total Tenant Improvement Allowance for the entire Demised
Premises, then provided that Tenant is not in default under this Lease, Landlord
shall pay any such excess to Tenant within thirty (30) days after the Tenant
Improvements are complete and Tenant has made its first payment of Annual Net
Rent.

     3.   Cost of and Payment for Tenant Improvements
          -------------------------------------------

          3.1  Tenant, at its sole expense, shall pay for the cost of all Tenant
Improvements constructed in the Demised Premises and Building pursuant to this
Workletter to the extent such cost exceeds the Tenant Improvement Allowance.

          3.2  Tenant shall conduct a selection process for a general contractor
("Tenant Contractor", with the Tenant Contractor, and all other contractors used
by Tenant or the Tenant Contractor, being referred to herein as the "Tenant
Contractors") to construct the Tenant Improvements among a list of general
contractors selected by Tenant and approved of by Landlord, which approval shall
not be unreasonably withheld. No award to the Tenant Contractor shall be made
without Landlord's prior approval in accordance with Section 1.3 of Part II of
this Workletter.

          3.3  The Tenant Improvement Allowance shall be payable by Landlord
to Tenant on a monthly progress payment basis, on the following terms and
conditions:

               (a) Each monthly payment of the Tenant Improvement Allowance
shall be the amount requisitioned by Tenant's architect, engineer, general
contractor for work completed during the prior month and approved for payment by
Tenant's independent architect, provided that if the cost of the Tenant
Improvement's (as evidenced by a fixed price general contract, or construction
management agreement with a guaranteed maximum price, therefor, a copy of which
shall be provided to Landlord prior to the first requisition hereunder, or
otherwise evidenced to the reasonable satisfaction of Landlord and its first
mortgagee) is greater than the Tenant Improvement Allowance, then Landlord shall
disburse the Tenant Improvement Allowance to Tenant on a pro-rata basis, with
Tenant funding the excess pro-rata.

               (b) After the first request, each request for a monthly payment
of the Tenant Improvement Allowance shall be accompanied by lien waivers (or if
not permitted by law, subordinations and evidences of payment) with

<PAGE>

respect to the work covered by the immediately preceding requisition (from the
general contractor and all subcontractors), and all work prior thereto, and such
other items as Landlord or its first mortgagee shall reasonably require.

                    (c) Each monthly payment of the Tenant Improvement Allowance
shall be paid by Landlord to Tenant within twenty (20) days after receipt by
Landlord of the documents required by Sections 3.3(a) and (b) above. In no event
shall any portion of the Tenant Improvement Allowance be payable by Landlord to
Tenant at any time when Tenant is in default under this Lease, beyond applicable
notice and cure periods.

          4.   Construction
               ------------

               4.1  Following: (i) Landlord's approval of the Final Plans; and
(ii) Tenant's receipt of all governmental approvals for the construction of the
Tenant Improvements (for which Tenant is responsible for obtaining governmental
approvals hereunder), the Tenant Contractor shall commence and diligently
proceed to construct and complete all Tenant Improvements. All of the provisions
of Article 10 of the Lease shall apply to the Tenant Improvements, provided that
is the event of any conflict between Article 10 and this Schedule D, the
provisions of this Schedule D shall govern.

               4.2  Tenant shall be fully responsible for payments to the Tenant
Contractor, the cost of prompt removal of all mechanics', materialmen's and like
liens for the Tenant Improvements from the public record by payment or surety
bond, costs to remove debris from the Demised Premises caused by the Tenant
Contractor or any subcontractors, costs prior to the Rent Commencement Date, and
utility and building service costs incurred by the Tenant Contractor. Tenant
shall require comprehensive general liability and worker's compensation
insurance and performance bonds from the Tenant Contractor in amounts and of the
types customarily required by owners of similar office buildings in the lower
Fairfield County Area, taking into consideration the reputation, size, credit
worthiness and financial standing of the Tenant Contractor. Landlord shall have
the right to waive any requirement for a performance bond by the Tenant
Contractor, based on Landlord's reasonable review of the Tenant Contractor's
credit worthiness and financial standing; provided, however, that such Tenant
Contractor must be bondable and must be able to post the necessary performance
bond if Landlord were to require the posting of such a bond. Tenant agrees to
enforce the Construction Contract, including all of the remedies therein for
breach thereof; in a diligent and prudent manner taking into consideration the
nature and scope of the Tenant Improvements.

               During construction of the Tenant Improvements, Tenant shall
obtain all risk physical damage insurance for the Tenant Improvements in the
Demised Premises and shall name Landlord as an additional insured in its policy.

     5.   Changes in Tenant's Final Plans
          -------------------------------

               5.1  Tenant may at any time request deletions, additions, or
alterations (collectively, "Changes") in its Final Plans and Landlord shall
review and approve or reject such Changes in accordance with the procedures set
forth in Section 1.2 hereof. Landlord's approval shall not be required with
respect to de minimis changes.

     6.   Tenant's Entry.
          ---------------

     Landlord agrees to cooperate with Tenant in scheduling the installation of
items by Tenant in the Demised Premises in order to avoid any delay in the
construction of the Tenant Improvements so as to avoid any material interference
with the normal operation of the Building. Landlord further agrees to cooperate
with Tenant in scheduling and providing, elevator, trash, and electricity use
and access in accordance with the respective rights and obligations of Tenant
and Landlord under Section 7 of this Workletter. Landlord shall work with Tenant
to facilitate the receiving of materials and the removal of debris in connection
with the performance of the Tenant Improvements. Landlord shall have no
liability and Tenant shall indemnify

<PAGE>

Landlord and its general contractor for any injury caused by a contractor to
Tenant's employees, contractors, agents or representatives, or for damage to any
property of Tenant, its employees, contractors, agents or representatives
occurring prior to the Rent Commencement Date, except to the extent caused by
Landlord's negligence. Landlord's indemnity obligations under Section 13.5(b) of
the Lease shall apply during the performance of the Tenant Improvements.

     7.   Building Services; Elevator, Hoisting
          -------------------------------------

          Landlord shall provide Tenant with elevators and reasonable access to
the Building, during the construction of the Tenant Improvements. As the total
charge to Tenant and the Tenant Contractor for the use of such elevators during
the construction of the Tenant Improvements, Tenant shall pay to Landlord only
Landlord's direct, incremental labor costs for providing such elevator services.

     8.   Default
          -------

          If not cured within thirty (30) days after written notice (or if cure
of such default is not commenced within such 30-day period and diligently
prosecuted to completion, where cure of such default cannot reasonably be
completed within such 30-day period), any default by a party under the terms of
this Workletter shall constitute a default under the Lease to which this
