|TA.3 | 24th Floor Effective Termination Date. The 24th Floor Effective Termination Date shall be defined as of December 31, 2003, provided however,
that if Landlord is unable to obtain the agreement (Early Termination Agreement) of the
21st Floor Tenant to terminate the Existing 21st Floor Lease as of September 30, 2003, or if
the 21st Floor Tenant does not vacate and deliver the New 21st Floor Premises on or before the expiration
or prior termination of the 21st Floor Lease, irrespective of whether Landlord is able to enter into
an Early Termination Agreement, then the 24th Floor Effective Termination Date shall be the earlier
of: (i) the day three months after the 21st Floor Tenant vacates the New 21st Floor Premises and
delivers the New 21st Floor Premises to Landlord, or (ii) the day that Tenant first commences to
use the New 21st Floor Premises, or any portion thereof, for business purposes; provided however,
that if Tenant exercises its right, in accordance with Section D.2 below, to cancel its demise of
the New 21st Floor Premises based upon the hold over by the 21st Floor Tenant in the New 21st Floor
Premises, then, subject to the provisions of Section D.3, the 24th Floor Effective Termination Date
shall be two (2) months after the New 21st Floor Premises Effective Cancellation Date, as defined
in Section D.2. Landlord will use its best efforts to enter into an Early Termination Agreement.
Irrespective of whether Landlord is able to enter into an Early Termination Agreement, if the 21st
Floor Tenant holds over in the New 21st Floor Premises after the termination of the Existing 21st
Floor Lease, Landlord shall use its best efforts (by commencing and diligently prosecuting summary
proceedings against the 21st Floor Tenant to recover possession of the New 21st Floor Premises as soon as possible).

|ARTICLE IIPREMISES
|                  

|2.1 | DEMISE AND LEASE OF PREMISES. Landlord hereby demises and leases to Tenant, and Tenant hereby hires and accepts from Landlord,
the Premises in the Building, excluding the portion of exterior walls outside of the inner face of
studs or similar line, the common stairways and stairwells, elevators and elevator walls, mechanical
rooms, electric and telephone closets, janitor closets, and pipes, ducts, shafts, conduits, wires
and appurtenant fixtures serving exclusively or in common other parts of the Building, and if the
Premises includes less than the entire rentable area of any floor, excluding the common corridors,
elevator lobbies and toilets located on such floor. Tenant hereby agrees with Landlord that, upon
the request of Landlord made from time to time, Tenant shall relocate from the Storage Premises then
demised to Tenant under this Lease (the Storage Premises) to other premises (which may
be more than one space) of at least substantially the same size and utility (in the aggregate if
more than one space) (the Relocated Storage Premises) within the Building and upon such
relocation the Relocated Storage Premises shall become part of the premises demised under this Lease.
Landlord, at its sole cost and expense, shall perform the partitioning of the Relocated Storage Premises
and shall place the same into substantially equivalent condition to that in which the Storage Premises
were in prior to such relocation, and Landlord shall also reimburse Tenant for Tenants reasonable
out-of-pocket moving expenses in so relocating

| | to the Relocated Storage Premises upon billing therefor from Tenant, which billing shall include reasonable
evidence thereof in the form of paid invoices, receipts and the like. Tenant shall not be required
to vacate the Storage Premises and to relocate to the Relocated Storage Premises until the Relocated
Storage Premises shall be substantially complete subject to punch list items and items of long lead
time. Upon any such relocation the Tenant shall enter into an amendment to this Lease confirming
such relocation, but the Tenants failure to enter into such amendment shall not affect in any
manner the relocation of the Storage Premises demised under this Lease from the Storage Premises
to the Relocated Storage Premises.

|    | (B)           Notwithstanding anything to the contrary herein, except as set forth in this Paragraph
(B), Landlord has no obligation to allow any particular telecommunication service provider (Telecom
Provider) to have access to the Building or to the Premises. Landlord agrees, subject to availability
of space and facilities in the Building and to Landlords approval of Tenants plans and
specifications for necessary installations in the Building, Landlord shall permit Tenant to substitute
a different Telecom Provider for the Telecom Provider that Tenant is presently using in the Building.
If Landlord permits such access, Landlord may condition such access upon the payment to Landlord
by the Telecom Provider of fees assessed by Landlord and the execution of a license agreement in
Landlords sole discretion; provided however, that: (i) Landlord shall not charge any fee to
Tenants current (i.e. as of the Execution Date of this Lease) Telecom Provider, (ii) so long
as Tenants Telecom Provider provides services in the Building only to Tenant, Landlord will
not charge any fee to Tenants Telecom Provider, and (iii) Landlord will not discriminate against
Tenants Telecom Provider in determining the amount of fees which it will charge to Tenants
Telecom Provider or in the form of license agreement imposed on Tenants Telecom Provider.

| | (C)           Landlord reserves for its benefit
and the benefit of any other PruOwner the right from time to time, without unreasonable interference
with Tenants use: (a) to install, use, maintain, repair, replace and relocate for service
to the Premises and other parts of the Building, or either, pipes, ducts, conduits, wires and appurtenant
fixtures, wherever located in the Premises or the Building, and (b) to alter or relocate any other
common facility, provided that substitutions are substantially equivalent or better. Installations,
replacements and relocations referred to in clause (a) above shall be located so far as practicable
in the central core area of the Building, above ceiling surfaces, below floor surfaces or within
perimeter walls of the Premises and shall not reduce the usable area or the ceiling heights of the
Premises. Except in the case of emergencies, Landlord agrees to use all reasonable efforts to give,
or cause such PruOwner to give, Tenant reasonable advance notice of any of the foregoing activities
which require work in the Premises. In making any entry into the Premises, Landlord shall use reasonable
efforts to minimize interference with the Tenants use and enjoyment of the Premises and shall
exercise reasonable care with regard to the safety of all persons and property in or about the Premises.

| | (D)          Landlord reserves and excepts for its
benefit and the benefit of any other PruOwner all rights of ownership and use in all respects outside
the Premises, including without limitation, the Building and all other structures and improvements
and plazas and common areas in the Prudential Center, except that at all times during the term of
this Lease Tenant shall have a reasonable means of access from a public street to the Premises and
from the parking garage and the loading areas serving the Building to the Premises. Without limitation
of the foregoing reservation of rights by Landlord, it is understood that in its sole discretion
Landlord or any other PruOwner, as the case may be, shall have the right to change and rearrange
the plazas and other common areas, to change, relocate and eliminate facilities therein, to erect
new buildings thereon, to permit the use of or lease all or part thereof for exhibitions and displays
and to sell, lease or dedicate all or part thereof to public use; and further that Landlord or any
other PruOwner, as the case may be, shall have the right to make changes in, additions to and eliminations
from the Building and other structures and improvements in the Prudential Center, the Premises and
the rights granted to Tenant pursuant to Section 16.32 below excepted; provided however that Tenant,
its employees, agents, clients, customers, and invitees shall at all times have reasonable access
to the Building and Premises. Notwithstanding the foregoing, Landlord hereby agrees that neither
Landlord or any affiliate of Landlord will block any of Tenants exterior windows with a party
wall. Tenant shall be permitted access to the Building and the Premises twenty-four (24) hours a
day, seven (7) days a week, subject to Landlords reasonable requirements for providing security
to the Building. Landlord is not under any obligation to permit individuals without proper building
identification to enter the Building after 6:00 p.m.

then demised to Tenant, as of the commencement of the Extended Term; provided however, that in no
event shall the Annual Fixed Rent during any Extended Term be less than the sum (Prior Rent)
of the Annual Fixed Rent plus the amount of Operating Cost Excess and Tax Excess payable by Tenant
in respect of the twelve month period immediately preceding the commencement of such Extended Term.
Tenant may request that Landlord advise Tenant of Landlords designation of the FMRV for the
Extended Term in question on or after the date twelve months prior to the expiration of the then
current term (in which event Landlord shall, within fifteen (15) days of its receipt of such request
so advise Tenant in writing), or Landlord may, at its own election advise Tenant of such FMRV at
any time on or after Tenant gives written notice exercising its option to extend the Term or the
Extended Term in question. If the parties have not agreed upon such FMRV within thirty (30) days
after Landlord advises Tenant of Landlords designation of such FMRV, then either party may
submit such dispute to arbitration in accordance with Section 5.4.

Extended Term, and the FMRV for such Extended Term is subsequently determined, either by agreement of the parties or
by arbitration, and if Tenant is not satisfied with such FMRV, then Tenant shall have the right to terminate the term
of the Lease by giving written notice (Termination Notice) to Landlord on or before the
date fifteen (15) days after such FMRV has been determined. In such event: (i) Tenant shall reimburse
Landlord for any costs which Landlord has incurred in the arbitration proceeding determining such
FMRV, (ii) the term of the Lease shall terminate as of the date (FMRV Effective Termination
Date) eighteen (18) months after Landlord receives such Termination Notice, (iii) the Annual
Fixed Rent and other charges payable by Tenant during any period of time between the date the then
current term would have expired but for the exercise by Tenant of its extension option and the FMRV
Effective Termination Date shall be equal to the greater of 95% of such FMRV or the Prior Rent, and
(iv) if such FMRV has not been determined prior to the commencement of the Extended Term in question,
then Tenant shall pay Annual Fixed Rent and other charges due under the Lease in respect of the Extended
Term in question based upon Prior Rent until either the agreement of the parties as to the Fair Market
Rental Value, or the decision of the arbitrators, as the case may be, at which time Tenant shall
pay any underpayment of rent and other charges to Landlord.

| | (B)           If Tenant exercises its Cancellation
Option with respect to a Removed Floor, Tenant, simultaneously with delivery of the Cancellation
Notice shall pay the applicable Cancellation Fee, as hereinafter defined, to Landlord. Tenant shall
have the right, from time to time, during the term of the Lease, to request that Landlord advise
Tenant of the amount of the Cancellation Fee. Landlord shall, within thirty (30) days after Landlords
receipt of such request, give Tenant written notice of the then current amount of the Cancellation
Fee for each Removed Floor and reasonable evidence (e.g. invoices, etc.) of the costs on which the
Cancellation Fee is based to the extent that Landlord has not previously provided such evidence to
Tenant. The Cancellation Fee shall be equal to the sum of: (1) the product of (x) the
unamortized portion of (i) the broker commissions paid to GVA Thompson, Doyle, Hennessey & Stevens
in connection with this Lease, (ii) the funded portion of Landlords Allowance, as defined in
Section 5.3(1), (iii) the funded portion of Landlords Additional Allowance, as defined in Section
5.3(2) of the Lease, (iv) the cost of Landlords Work, and (v) attorneys fees paid by
Landlord in connection with the negotiation and documentation of this Lease multiplied by (y) 12.5%;
plus (2) an amount equal to nine (9) months Annual Fixed Rent, Operating Cost Excess, and Tax Excess,
at the then (i.e. as of the Effective Termination Date) applicable rate for and with

| | respect to the Removed Floor on a per square foot basis. Because at the time of the giving of the Cancellation
Notice the amount of the Operating Cost Excess and Tax Excess in effect as of the Effective Termination
Date will not be known, Tenant shall pay on account of the Cancellation Fee in respect of Operating
Cost Excess and Tax Excess calculated at the rate in effect at the time that the Cancellation Notice
is given and once the Operating Cost Excess and Tax Excess in effect as of the Effective Termination
Date is known there shall be a prompt adjustment between Landlord and Tenant with Landlord to pay
Tenant any overpayment and Tenant to pay Landlord any underpayment, such obligation to continue after
the Effective Termination Date. Tenant shall remain liable for all Annual Fixed Rent, Additional
Rent and other sums due under the Lease in respect of the Removed Floor up to and including the Effective
Termination Date even though billings for such may occur subsequent to the Effective Termination
Date. The unamortized portion of any of the foregoing shall be determined over the Original
Lease Term on a level direct reduction basis using an interest rate of 10.5% per annum.

Landlord with a Cancellation Notice, any unexercised rights or options of Tenant to expand the Premises
(whether expansion options, rights of first or second refusal, rights of first or second offer, or
other similar rights), shall immediately be deemed terminated and no longer available or of any further
force or effect, and any outstanding tenant improvement allowance not claimed and properly utilized

fire command station for the Building as may be required by Applicable Law in connection with the
initial improvements made by Tenant in any portion of the Premises after the Execution Date of this
Lease, including, without limitation, the New 21st Floor Premises, and (ii) recalibrate and clean
all perimeter induction units on each floor of the Office Premises and rezone all perimeter induction
units (including adding a new thermostat for each corner office) within all corner offices on floors
15-20, 21 and 23 (collectively HVAC Work). Landlord shall perform Landlords Work
pursuant to a schedule to be mutually agreed upon by Landlord and Tenant, provided that, in any event,
the schedule for the performance of the Fire Command Assess Work to be performed with respect to the New 21st Floor Premises shall allow sufficient time to enable Landlord to substantially complete such work
on or before the Outside 21st Floor Rent Commencement Date, as defined in Section D.1(a) above. Notwithstanding anything to the
contrary herein contained, the performance and completion of Landlords Work shall have no effect
on the Commencement Date or the Commencement Date with respect to the New 21st Floor Premises. Landlord
shall coordinate such work with Tenant to minimize any disruption of Tenants business, provided
however, that, except as set forth in Section D.1(c) above, Tenant shall not be entitled to any diminution

| | (2)           Performance of Tenants Work. After the Plans have been approved by Landlord, Tenant, at its sole cost and expense (subject to
Landlords Allowance and Landlords Additional Allowance), shall promptly, and with all
due diligence, perform Tenants Work as set forth on the Plans, and, in connection therewith,
the Tenant shall obtain all necessary governmental permits and approvals for such work. All of Tenants
Work shall be performed strictly in accordance with the Plans and in accordance with applicable Legal
Requirements (as defined in Section 4.2 hereof) and Insurance Requirements (as defined in Section
9.1 hereof). Tenant shall have such work performed by contractors, reasonably approved by Landlord,
which contractors shall provide to Landlord such insurance as is required pursuant to Exhibit M.
If Tenant engages Landlord to oversee and manage Tenants contractors, Tenant shall pay to Landlord
a construction management fee equal to two (2%) percent of the cost of Tenants Work, and Landlord
shall have the right to deduct such construction management fee from Landlords Allowance. Landlord
shall have the right to provide reasonable rules and regulations relative to the performance of such
work and any other work which the Tenant may perform under this Lease and Tenant shall abide by all
such reasonable rules and regulations and shall cause all of its contractors to so abide. It shall
be Tenants obligation to obtain a certificate of occupancy or other like governmental approval
for the use and occupancy of the New 21st Floor Premises, and Tenant shall not open for business
in the New 21st Floor Premises until and unless it has obtained such approval to the extent that
such approval is required by law and has submitted to Landlord a copy of the same. If Tenant is delayed
in obtaining a certificate of occupancy with respect to the New 21st Floor Premises due to deficiencies
in the Building not related to the New 21st Floor Premises, Landlord shall cooperate with Tenant
in such manner as Tenant may reasonably request to mitigate or cure such deficiencies to the extent
necessary to enable Tenant to obtain such certificate of occupancy as promptly as possible. If Tenant
is delayed in obtaining a certificate of occupancy with respect to the New 21st Floor Premises solely
as the result of deficiencies in the Building not related to New 21st Floor Premises, then Tenant
shall promptly so advise Landlord in writing, and the Outside 21st Floor Rent Commencement Date shall
be extended by the number of days between the

|    | date that Landlord receives such notice and the date that Landlord cures such deficiencies in the Building
sufficiently to enable Tenant to obtain such certificate of occupancy. Tenant shall submit to Landlord
promptly after the Tenants Work is substantially complete the so-called contractors set
of plans for such work.

New 21st Floor Premises Commencement Date, as defined in Section B.7, will occur prior to September
1, 2004 because Landlord is able to enter into an agreement with the Existing 21st Floor Tenant to
terminate the 21st Floor Lease prior to August 31, 2004, then the Plan Submission Date shall be the

Tenant has delivered to Landlord lien waivers from all persons with contracts with a value in excess
of $25,000.00 who might have a lien as a result of Tenants Work, in recordable form (Landlord
acknowledging that Tenant shall not be able to a lien waiver from a contractor in connection with
such contractors first application for payment), (ii) Tenant has delivered to Landlord its
certificate as to the cost of such Tenants Work, together with evidence thereof in the form
of paid invoices, receipts and the like, (iii) Tenant has made request for such payment on or before
August 31, 2007 (Outside Requisition Date), except that if the Commencement Date in respect
of the New 21st Floor Premises does not occur on or before September 1, 2004, then, with respect
to costs incurred by Tenant with respect to the New 21st Floor Premises not to exceed $131,281.01,
the Outside Requisition Date shall be the date three years after the New 21st Floor Premises Commencement
Date, and (iv) no Event of Default of Tenant described in clauses (a) or (d) of Section 15.1 of the
Lease is outstanding and no condition described in clauses (b), (e), (f), (g), (h), (i), (j), or
(k) of Section 15.2 has occurred and is outstanding, then within thirty (30) days after the satisfaction
of the foregoing conditions, the Landlord shall pay to the Tenant the amount of such costs so certified
up to the Landlords Allowance. Tenant may not submit a requisition for payment on account of
Landlords Allowance more than one time in any calendar month. Tenant may submit requisitions
for payment to Landlord on account of Landlords Allowance after the Execution Date of this
Lease. Tenant shall have no right to any unused portion of Landlords Allowance, nor shall there
be any application of the same toward Annual Fixed Rent or Additional Rent owed by Tenant under this
Lease. If Landlord fails timely to pay any portion of Landlords Allowance or the Bathroom Allowance
properly payable to Tenant when due, then Tenant shall have the right to deduct such amount from
the next installments (s) of the Annual Fixed Rent and other charges due under the Lease.

of the Bathroom Renovations, it is discovered that there are latent defects in the plumbing or sanitary
systems serving the bathrooms in which the Bathroom Work is being performed, then Landlord shall
repair such defects. Landlord shall coordinate such work with the performance of the Bathroom Renovations,

|                                                                               

| | (A)          Fair Market Rental Value
shall be computed as of the date in question at the then current annual rental charge (i.e., the
sum of Annual Fixed Rent plus escalation and other charges), including provisions for subsequent
increases and other adjustments for leases or agreements to lease then currently being negotiated
or executed for comparable space located in first-class office buildings of similar size and quality
within the Back Bay Market, including the Prudential Center (Market Area). In determining
Fair Market Rental Value, all relevant, factors will be used, including, without limitation, responsibility
(or no responsibility) for brokers fees, leasehold improvements, free rent, and other reasonable
concessions then being given in the market, as well as size, location of premises, lease term, condition
of building, condition of premises, and services provided by the landlord.

|5.5 | CONSTRUCTION RENT.  If Tenant elects to have Landlord provide Landlords Additional Allowance pursuant to Section
5.3(2) and Landlord provides Landlords Additional Allowance, then, with respect to the funds
advanced by Landlord pursuant to each Additional Allowance Requisition, Tenant shall pay to Landlord,
as additional rent, Construction Rent, as hereinafter defined, based upon the amount of Landlords
Additional Allowance advanced by Landlord pursuant to such Additional Allowance Requisition. Tenants
monthly payments of Construction Rent based upon each Additional Allowance Requisition shall be equal
to the amount of equal monthly payments of principal and interest which would be necessary to repay
a loan in the amount of the funds advanced by Landlord pursuant to such Additional Allowance Requisition,
together with interest at the rate of ten and one-half (10.5%) percent per annum, on a level direct
reduction basis over the period commencing as of the Landlords Allowance Date, as hereinafter
defined, with respect to such Additional Allowance Requisition and ending as of the expiration of
the Original Lease Term. Landlords Allowance Date with respect to each Additional
Allowance Requisition shall be the first day of the calendar month next following Landlords
payment of the funds due under such Additional Allowance Requisition. Monthly payments of Construction
Rent shall be payable at the same time and in the same manner as Annual Fixed Rent is payable under
the Lease. Construction Rent shall not be abated or reduced for any reason whatsoever (including,
without limitation, untenantability of the Premises or termination of the Lease; except that, if
this Lease terminates as a result of a fire or casualty, and Landlord receives net insurance proceeds
that are allocable to the Tenants Work paid for by the Landlords Additional Allowance,
then the amount thereof shall be credited against the Construction Rent thereafter to be paid. Without
limiting the foregoing, the rent abatement provisions of Articles VII and XIV of the Lease shall
not apply to Construction Rent. If there is any default (beyond the expiration of any applicable
grace periods) of any of Tenants obligations under the Lease (including, without limitation,
its obligation to pay Construction Rent) or if the Term of this Lease is terminated for any reason
whatsoever prior to the Termination Date, Tenant shall pay to Landlord, immediately upon demand,
the unamortized balance of Landlords Additional Allowance. Tenants obligation to pay
the unamortized balance of Landlords Additional Allowance shall be in addition to all other
rights and remedies which Landlord has based upon any default of Tenant under the Lease, and Tenant
shall not be entitled to any credit or reduction in such payment based upon amounts collected by
Landlord from reletting the premises after the default of Tenant.

| | (d) | Real estate taxes means all taxes and special assessments of every kind and nature and
user fees and other like fees assessed by any Governmental authority on, or allocable to (i) the
Building or (ii) the land, open areas, public areas and amenities, plazas, common areas and other
non-leasable areas of the Prudential Center (for the purposes of this Subsection (d) Common
Areas) which the Landlord shall be obligated to pay because of or in connection with the ownership,
leasing or operation of the Building and reasonable expenses of any proceedings for abatement of
taxes to the extent not included in Operating Expenses. The amount of special taxes or special assessments
to be included shall be limited to the amount of the installment (plus any interest other than penalty
interest payable thereon) of such special tax or special assessment required to be paid during the
year in respect of which such taxes are being determined. There shall be excluded from such taxes
all income, estate, succession, gift, inheritance, sales, corporate excise, interest or penalties
incurred as the result of late payment of taxes by Landlord, and transfer taxes; provided, however,
that if at any time during the Lease Term the present system of ad valorem taxation of real property
shall be changed so that in lieu of, or in addition to, the whole or any part of the ad valorem tax
on real property, there shall be assessed on Landlord a capital levy or other tax on the gross rents
received with respect to the Building, or a Federal, State, County, Municipal, or other local income,
franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect in
the jurisdiction in which the Prudential Center is located) measured by or based, in whole or in
part, upon any such gross rents, then any and all of such taxes, assessments, levies or charges,
to the extent so measured or based, shall be deemed to be included within the term real estate
taxes but only to the extent that the same would be payable if the Building, were the only
property of Landlord. To the extent that the Building is not separately assessed for real estate
tax purposes, but is assessed as part of a larger parcel without a separate identification of assessed
value of the Building by the assessing authority, then the Landlord shall make a reasonable allocation
as to the amount of the real estate taxes that should be allocated to the Building for the purposes
of determination of the Tenants share of increases in real estate taxes under this Lease. The
Landlords reasonable allocation, if made

|-30-

| |     | in good faith shall be final. For the purposes of this Lease, real estate taxes shall include any payment
in lieu of taxes or any payments made under Chapter 121A of the Massachusetts General Laws or any
similar law. Notwithstanding the foregoing, if, and to the extent that, it is determinable from the
records of the assessing authority that an increase in Taxes is based solely upon alterations, additions
or improvements which are above Building standard quality set forth in Exhibit N within the premises
of any tenant, then such increase shall not be included in Taxes. For any Tax Year in which the assessing
authority determines the assessed value of the Building and the land based upon an income approach,
then the immediately preceding sentence shall not apply.

respect to any full Tax Year or fraction of a Tax Year falling within the Lease Term Landlords
Tax Expenses Allocable to the Premises for a full Tax Year exceed Base Taxes Allocable to the Premises
or for any such fraction of a Tax Year exceed the corresponding fraction of Base Taxes Allocable
to the Premises (such amount being hereinafter referred to as the Tax Excess), then Tenant
shall pay to Landlord, as Additional Rent, the amount of such Tax Excess. Payments by Tenant on account
of the Tax Excess shall be made monthly at the time and in the fashion herein provided for the payment
of Annual Fixed Rent. The amount so to be paid to Landlord shall be an amount from time to time reasonably
estimated by Landlord to be sufficient to provide Landlord, in the aggregate, a sum equal to the
Tax Excess, ten (10) days at least before the day on which tax payments by Landlord would become
delinquent. Not later than ninety (90) days after Landlords Tax Expenses Allocable to the Premises
are determinable for the first such Tax Year or fraction thereof and for each succeeding Tax Year
or fraction thereof during the Lease Term, Landlord shall render Tenant a statement in reasonable
detail certified by a representative of Landlord showing for the preceding year or fraction thereof,

of the Tax Excess, the amount thereof already paid by Tenant and the amount thereof overpaid by,
or remaining due from, Tenant for the period covered by such statement. Within thirty (30) days after
the receipt of such statement, Tenant shall pay any sum remaining due. Any balance shown as due to
Tenant shall be credited against Annual Fixed Rent next due, or if the Lease Term has or will expire
before the credit is used, refunded to Tenant when the Lease Term has expired and Tenant has no further
obligation to Landlord. Reasonable expenditures for legal fees and for other expenses incurred in
obtaining an abatement or refund and not previously included in real estate taxes paid by Tenant
or included in Operating Expenses paid by Tenant may be charged against the abatement or refund before
the adjustments are made for the Tax Year.

| | (10) | depreciation for capital improvements (x) to reduce Operating Expenses if Landlord reasonably shall
have determined that the annual reduction in Operating Expenses shall exceed depreciation therefor
or (y) to comply with Legal Requirements (plus, in the case of both (x) and (y), the actual interest
rate incurred by Landlord with respect to such capital improvement, or, if Landlord does not used
borrowed funds to pay for such capital improvement, an interest factor, reasonably determined by
Landlord, as being the interest rate then charged for long term mortgages by institutional lenders
on like properties within the general locality in which the Building is located), and in the case
of both (x) and (y) depreciation shall be determined by dividing the original cost of such capital
expenditure by the number of years of useful life of the capital item acquired, which useful life
shall be determined reasonably by Landlord in accordance with generally accepted accounting principles
and practices in effect at the time of acquisition of the capital item; provided, however, if Landlord
reasonably concludes on the basis of engineering estimates that a particular capital expenditure
will effect savings in other Operating Expenses, including, without limitation, energy related costs,
and that such projected savings will, on an annual basis (Projected Annual Savings),
exceed the annual depreciation therefor, then and in such event the amount of depreciation for such
capital expenditure shall be increased to an amount equal to the Projected Annual Savings; and in
such circumstance, the increased depreciation (in the amount of the Projected Annual Savings) shall
be made for such period of time as it would take to fully amortize the cost of the item in question,
together with interest thereon at the interest rate as aforesaid in equal monthly payments, each
in the amount of 1/12th of the Projected Annual Savings, with such payment to be applied first to
interest and the balance to principal; and

any such examination, Tenant and its examiners shall be required to execute and deliver to Landlord
an agreement, in form reasonably acceptable to Landlord, agreeing to keep confidential any information
which it discovers about Landlord or the Building in connection with such examination. Landlord shall,
within ten (10) days of written request, provide to Tenant the form of such agreement. Without limiting
the foregoing, if Tenant uses any examiner which is other than a nationally recognized accounting
firm, Tenants examiner shall be required to agree that it will not represent any other tenant
in the Building or in other buildings located in the Prudential Center which is owned by Landlord
or an affiliate of Landlord in connection with reviewing operating expenses for such tenant.

replacements, or improvements made by Landlord, (ii) Landlords failure to make any repairs,
alterations, or improvements required to be made by Landlord hereunder, or to provide any service
required to be provided by Landlord hereunder, or (iii) failure of electric supply, any portion of
the Premises becomes untenantable so that for the Premises Untenantability Cure Period, as hereinafter
defined, the continued operation in the ordinary course of Tenants business is materially adversely
affected, then, provided that Tenant ceases to use the affected portion of the Premises during the
entirety of the Premises Untenantability Cure Period by reason of such untenantability, and that
such untenantability and Landlords inability to cure such condition is not caused by the fault
or neglect of Tenant or Tenants agents, employees or contractors, Annual Fixed Rent, Operating
Cost Excess, and Tax Excess shall thereafter be abated in proportion to such untenantability and
its impact on the continued operation in the ordinary course of Tenants business until the
day such condition is completely corrected. For the purposes hereof, the Premises Untenantability
Cure Period shall be defined as five (5) consecutive business days after Landlords receipt
of written notice from Tenant of the condition causing untenantability in the Premises, provided
however, that the Premises Untenantability Cure Period shall be fifteen (15) consecutive business
days after Landlords receipt of written notice from Tenant of such condition causing untenantability
in the Premises if either the condition was caused by causes beyond Landlords reasonable control
or Landlord is unable to cure such condition as the result of causes beyond Landlords reasonable
control. The provisions of this clause (C) shall not apply in the event of untenantability caused
by fire or other casualty, or taking (see Article XIV).

| | (D)          Tenants Termination Right. Notwithstanding anything to the contrary herein contained, if due to (i) Landlords failure
to make any repairs, alterations or improvements required to be made by Landlord under the Lease,
or (ii) any interruption in essential services which Landlord is required to provide to Tenant hereunder,
any material portion of the Premises becomes untenantable for a period (Untenantability Period)
of five (5) consecutive months (which five (5) month period shall be extended by the period of time,
which shall not exceed an additional two (2) months, that Landlord is delayed in curing such condition
as the result of causes beyond Landlords reasonable control) after Landlords receipt
of written notice of such condition from Tenant, then, provided that Tenant ceases to use the affected
portion of the Premises during the entire period of such untenantability, such untenantability and
Landlords inability to cure such condition is not caused by a cause beyond Landlords
reasonable control or the fault or neglect of Tenant, or Tenants agents, employees or contractors,
then Tenant may terminate this Lease as to the entire Premises, or the affected portion of the Premises,
by giving Landlord written notice as follows:

require to perform such repairs, provided that Tenant commences such repairs within such thirty (30)
day period and diligently prosecutes such repairs to completion), Landlord may (but shall not be

Tenant agrees that Tenant will, within thirty (30) days of demand, pay to Landlord as Additional
Rent the reasonable cost thereof together with interest thereon at the rate specified in Section
16.21, and if Tenant shall default in such payment, Landlord shall have the remedies provided for
non-payment of rent or other charges payable hereunder.

|     | (c)  By notice to Landlord given no later than the third anniversary of the date of execution
hereof (the Parking Notice Date), Tenant may require Landlord to construct a reserved
parking area (the New Area) in a location in the Garage shown on Exhibit J hereto for
Tenants Reserved Spaces, and Landlord shall construct the same which shall include, inter alia, a gate and enclosure. Landlord anticipates that the number of reserved parking spaces that will be
created in the New Area may be more than 12 parking spaces, and that other tenants and/or parkers
will be using such other (i.e. other than the Reserved Spaces) spaces in the New Area. Upon the completion
of the New Area, Landlord shall bill Tenant for all the costs and expenses which it has incurred
in constructing such New Area and putting in the same into operation, including, without limitation,
the costs of installing and putting into operation the gate system, and Landlord shall submit with
such billing reasonable back-up evidence thereof and Tenant shall reimburse Landlord for such costs
within thirty (30) days after receipt of such billing. The monthly charge per space for the spaces
within such New Area shall commence as of the substantial completion of the New Area and shall initially
shall be $600 per space. Such rate shall be in effect until the Parking Notice Date and thereafter
such rate shall increase proportionately with any increases in the prevailing monthly rates for reserved
parking within the Garage. Prior to the substantial completion of the New Area, parking charges for
reserved spaces shall be in accordance with Section 10.2. Tenant acknowledges that Landlord may charge
other users of reserved spaces in the New Area such rate as Landlord may determine, from time to
time, in Landlords sole discretion.

|10.2 | PARKING CHARGES. Subject to the provisions of Section 10.1B, Tenant shall pay for such parking privileges at the prevailing
monthly rates from time to time charged by the operator or operators of the Garage to tenants of
the Prudential Center for unreserved or reserved parking, as applicable, whether or not such operator
is an affiliate of Landlord. Such monthly parking charges for parking privileges shall constitute
Additional Rent and shall be payable monthly as directed by Landlord upon billing therefor by Landlord
or such operator. Tenant acknowledges that said monthly charges to be paid under this Section are

|     | and Tenant shall be obligated to park and remove its own automobiles, and, except for the reserved
parking privileges set forth in Section 10.1, Tenants parking shall be on an unreserved basis,
Tenant having the right to park in any available stalls. Tenants access and use privileges
with respect to the Garage shall be in accordance with regulations of uniform applicability to the
users of the Garage from time to time established by the Landlord or the Garage Operator. Tenant
shall receive one (1) identification sticker or pass and one (1) magnetic card so-called, or other
suitable device providing access to the Garage, for each parking privilege paid for by Tenant. Tenant
shall supply Landlord with an identification roster listing, for each identification sticker or pass,
the name of the employee and the make, color and registration number of the vehicle to which it has
been assigned, and shall provide a revised roster to Landlord monthly indicating changes thereto.
Any automobile found parked in the Garage during normal business hours without appropriate identification
will be subject to being towed at said automobile owners expense. The parking privileges granted
herein are non-transferable (other than to a permitted assignee or subtenant pursuant to the applicable
provisions of Article XII hereof). Landlord or the Garage Operator may institute a so-called valet
parking program for the Garage, and in such event Tenant shall cooperate in all respects with such
program. Landlord reserves for itself and any other PruOwner the right to alter the Garage as it
sees fit and in such case to change the Garage including the reduction in area of the same, Tenant
acknowledging that in connection with the potential expansion of buildings in the Prudential Center
or the addition of other buildings thereto, it may be necessary to make significant changes to the
Garage which may result in the reduction of the amount of parking available in the Garage and the
change of location of such parking or may change the access to or egress from the Garage, all of
which Landlord or any other PruOwner may perform in its sole and exclusive discretion, without limitation
to its other rights in respect thereof. Subject to causes beyond Landlords reasonable control,
the holder of any magnetic card shall have access to the Garage, 24-hours per day, seven days per week throughout the term of this Lease.

and 12.4 below, but subject to the provisions of Sections 12.5 and 12.7, Tenant shall have the right to assign this Lease
or to sublet the Premises (in whole or in part) to any controlling entity of either Arnold Worldwide
LLC or Havas, S.A., to any entity controlled by either Arnold Worldwide LLC or Havas S.A., or to
any entity under common control with Arnold Worldwide LLC, Havas S.A., any other parent or subsidiary
entity or entity under common control with Arnold Worldwide LLC or Havas, S.A. being hereinafter
called a Tenant Affiliate) or to any corporation, limited liability partnership or limited
liability company into which either Arnold Worldwide LLC or Havas, S.A. may be converted or with
which it may merge, or to any entity purchasing all or substantially all of the assets of either
Arnold Worldwide LLC or Havas, S.A. (each, a Permitted Tenant Successor), provided that
in the case of a Permitted Tenant Successor (but not in the case of a Tenant Affiliate where both
of the original Tenant entities continues to exist), the entity to which this Lease is so assigned
or which so sublets the Premises, together with the other Tenant entity (if any) remaining in existence,
have a net worth (e.g. assets on a pro forma basis using generally accepted accounting principles
consistently applied and using the most recent financial statements) equal to at least the aggregate
net worth of the then existing Tenant entities immediately before such transaction. If any Tenant
Affiliate to which this Lease is assigned or the Premises sublet (in whole or in part) shall cease
to be such a Tenant Affiliate, and such cessation was intended at the time of the assignment or subletting,
the provisions of this Section 12.2 shall not apply to such assignment or subletting. For the purposes
of this Section 12.2, the term control shall mean ownership of not less than thirty (30%)
percent of all of the voting stock of a corporation or not less than thirty (30%) percent of all
of the legal and equitable interest in any other business entity if Tenant is not a corporation,
or the ability, whether by the ownership of shares or other equity interest, by contract or otherwise,
to elect a majority of the directors in the case of a corporation or if not a corporation, to make
management decisions on behalf of such entity. It shall be conditions to any assignment or sublease
effected pursuant to this Section 12.2 that: (x) Tenant deliver to Landlord evidence, reasonably
satisfactory to Landlord, that the subtenant or assignee, as the case may be, is a Permitted Tenant
Successor or a Tenant Affiliate, as the case may be, and (y) such transaction is not entered into
solely for the purposes of avoiding the restrictions set forth in this Article 12.

receipt of the Recapture Offer to accept a Recapture Offer. If the Recapture Premises constitute
a floor or less, then the Acceptance Period shall be thirty (30) days; otherwise, the Acceptance
Period shall be sixty (60) days. In the event that Landlord shall not timely exercise its termination
rights as aforesaid, or shall fail to give any or timely notice pursuant to this Section, the provisions
of Sections 12.4-12.7 shall be applicable. If the Recapture Premises includes a portion of a floor,
then, whether or not Landlord accepts the Recapture Offer, Tenant shall be responsible for 50% of
the cost of demising such space from the balance of the Premises on that floor, of creating building
standard common partitions on such floor, and for 50% of the cost of creating common facilities (e.g.
elevator lobbies, common corridors, and common bathrooms) on such floor. This Section 12.3 shall
not be applicable to an assignment or sublease pursuant to Section 12.2.

brokerage commissions, reasonable attorneys fees, cost of alterations and alteration allowances)
amortized over the term of the sublease or assignment, and the fair market value of any furniture,
fixtures or equipment sold or leased by Tenant to such assignee or subtenant, provided that Tenant
delivers to Landlord reasonable evidence of the fair market value of such furniture, fixtures, or equipment.

reasonably required by Landlord, to be bound by all the obligations of the Tenant hereunder, including,
without limitation, the obligation to pay the Annual Fixed Rent, Additional Rent, and other amounts
provided for under this Lease (but in the case of a partial subletting pursuant to Section 12.2,
such subtenant shall agree on a pro rata basis to be so bound and only as to the portion of the Premises
to be sublet) including the provisions of Sections 12.1 through 12.7 hereof, but such assignment
or subletting shall not relieve the Tenant named herein of any of the obligations of the Tenant hereunder,
Tenant shall remain fully and primarily liable therefor and the liability of Tenant and such assignee
(or subtenant, as the case may be) shall be joint and several. Further, and notwithstanding the foregoing,
the provisions hereof shall not constitute a recognition of the assignment or the assignee thereunder
or the sublease or the subtenant thereunder, as the case may be, and at Landlords option, upon
the termination of the Lease, the assignment or sublease shall be terminated.

the scope of Landlords indemnity, provided that: (i) Tenant is not required to pay any portion
of such settlement, (ii) Tenant is released from any ongoing liability arising therefrom, (iii) such
settlement does not impose an admission of liability on the part of Tenant, and (iv) such settlement
is for money damages only.

|13.4 | NON-SUBROGATION. Any insurance carried by either party with respect to the Premises or property therein or occurrences
thereon shall, if it can be so written without additional premium or with an additional premium which
the other party agrees to pay, include a clause or endorsement denying to the insurer rights of subrogation
against the other party to the extent rights have been waived by the insured prior to occurrence
of injury or loss. Landlord and Tenant hereby release each other from any and all liability or responsibility
to the other or anyone claiming through or under them (including, without limitation, Tenants
release of Landlords managing agent) by way of subrogation or otherwise for any loss or damage
to property caused by fire or any of the extended coverage or supplementary contract casualties,
even if such fire or other casualty shall have been caused by the fault or negligence of the other

|13.6 | LANDLORDS INSURANCE. Landlord shall carry at all times during the Term of this Lease (and the specific coverages listed
below shall be adjusted to reflect current values from time to time) (i) commercial general liability
insurance with respect to the Building in an amount not less than $5,000,000.00 combined single limit
per occurrence, (ii) with respect to the Building, including all work which Landlord or Tenant initially
installs as leasehold improvements in the Premises pursuant to Article IV, insurance against
loss or damage caused by any peril covered under fire, extended coverage and all risk insurance with
coverage against vandalism, malicious mischief and such other insurable hazards and contingencies
as are from time to time normally insured against by owners of first-class multi-tenant office buildings
in Boston or which are required by Landlords mortgagee, in an amount equal to one hundred percent
(100%) of the full replacement cost thereof above foundation walls. Further, Landlord may also maintain
such insurance against loss of Annual Fixed Rent and Additional Rent for up to twelve months (or
such longer period of time as Landlords mortgagee may require) and such other risks and perils
as Landlord deems proper, consistent with other first class office buildings in the City of Boston.
Any and all such insurance (i) may be maintained under a blanket policy affecting other properties
of Landlord and/or its affiliated business organizations, (ii) may be written with deductibles as
determined by Landlord (which deductibles initially shall not exceed $25,000.00, but such amount
shall be increased throughout the Term of this Lease, consistent with other first class office buildings
in the City of Boston) and (iii) shall be subject to escalation reimbursement in accordance with Section 7.2.

such substantial alteration or reconstruction of the Building that the damage cannot, in the ordinary
course, reasonably be expected, based upon an Engineering Estimate, as defined in Section 14.1(C)
to be repaired within ten (10) months from the date of such fire or casualty as reasonably determined
in the Engineering Estimate and Landlord terminates the leases for substantially all of the office

shall be substantially damaged by fire or casualty as the result of a risk not covered by the forms
of casualty insurance required under this Lease to be maintained, or otherwise maintained, by Landlord
and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired
within thirty (30) days from the time that repair work would commence, which is confirmed by the
Engineering Estimate, or (ii) if the holder of any mortgage or any ground lessor will not allow the
net proceeds of insurance to be applied to the restoration of the Building, or (iii) if the net insurance
proceeds shall be insufficient to complete such repairs and restoration, Landlord may, at its election,
terminate the Term of this Lease by notice to Tenant given within sixty (60) days after such loss.
If Landlord shall give such notice, then this Lease shall terminate as of the date specified in such
notice, which shall be not less than thirty (30) days after the day on which such termination notice
is received by Tenant, with the same force and effect as if such date were the date originally established
as the expiration date hereof. It shall be a condition to Landlords exercise of its termination
right pursuant to this Section 14.1(B), that Landlord exercise its right to terminate the leases
of all of the office tenants in the Building.

or other casualty to the extent that the operation of Tenants business in the Premises in the
normal course is materially adversely affected, then, within forty-five (45) days of such fire or

Estimate) from a reputable engineering firm as to the estimated length of time (Estimated
Restoration Period) to complete such repairs together with a statement of whether or not Landlord

to the restoration of the Building, or if the net insurance proceeds shall be insufficient to complete
such repairs and restoration and, in either such case, that Landlord will not be funding such restoration.
In such event, Tenant shall have the right to terminate the Lease, by written notice given to Landlord
within thirty (30) days of Tenants receipt of Landlords notice of insufficient proceeds,
the effective termination date of which shall be not less than forty-five (45) days after the day
on which such termination notice is received by Landlord.

Lease is not so terminated, or Landlord has no right to terminate this Lease, and in either such
case the holder of any mortgage which includes the Building as a part of the mortgaged premises or
any ground lessor of any ground lease which includes the Building as part of the demised premises

Premises, Landlord, promptly after such damage and the determination of the net amount of insurance
proceeds available shall use due diligence to restore the Premises and the Building in the event
of damage thereto into substantially the same condition which existed immediately prior to such
fire or casualty (excluding Tenants Property) and a just proportion of the Annual Fixed Rent
and the Operating Cost Excess according to the nature and extent of the injury to the Premises (or
Tenants means of access thereto) shall be abated from the date of casualty until the Premises
(and Tenants means of access thereto) shall have been put by Landlord into such condition or
this Lease shall have been terminated as permitted herein.

of possession. In addition, if Tenant loses its right to park more than twenty (20%) percent of the
vehicles which it has the right to park in the Garage pursuant to Section 10.1, then Tenant shall
have the right to terminate this Lease by notice to Landlord, provided that such notice is given
not later than thirty (30) days after such loss of parking. If either party shall give a termination

would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this
Lease (Tenants liability prior to any such reletting and such recovery not in any way to be
diminished as a result of the fact that such reletting might be for a rent higher than the rent provided
for in this Lease); when and if such expenses have been completely recovered, the amounts received
from reletting by Landlord as have not previously been applied shall be credited against Tenants
obligations as of each day when a payment would fall due under this Lease, and only the net amount

markets other premises within Landlords control in the Prudential Center shall be deemed to
have satisfied Landlords obligation to use reasonable efforts. In no event

above, and whether or not Landlord shall have collected any damages as hereinbefore provided in this
Article XV, and in lieu of all other such damages beyond the date of such notice. Upon such notice,

or due from Tenant from any period prior to such notice and all expenses which Landlord may have
incurred with respect to the collection of such damages, such a sum as at the time of such notice

of 6%, of the Annual Fixed Rent, Additional Rent and other charges which would have been payable
by Tenant under this Lease for the remainder of the Lease Term if the Lease terms had been fully
complied with by Tenant, over and above (b) the discounted present value, at a discount rate of 6%,
of the Annual Fixed Rent, Additional Rent and other charges that would be received by Landlord if
the Premises were re- leased at the time of such notice for the remainder of the Lease Term at the
fair market value (including provisions regarding periodic increases in Annual Fixed Rent if such
are applicable) prevailing at the time of such notice as reasonably determined by Landlord.

respectively, of any of its rights hereunder.

as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions
hereof shall not be construed as a waiver at any subsequent time of the same provisions. The consent
or approval of Landlord or Tenant to or of any action by the other requiring such consent or approval
shall not be construed to waive or render unnecessary Landlords or Tenants consent or
approval to or of any subsequent similar act by the other.

|     | No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to
Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a
check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying
such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may
accept such check without prejudice to any other rights or remedies which Landlord may have against
Tenant. Further, the acceptance by Landlord of Annual Fixed Rent, Additional Rent or any other charges
paid by Tenant under this Lease shall not be or be deemed to be a waiver by Landlord of any default
by Tenant, whether or not Landlord knows of such default, except for such defaults as to which such
payment relates. Tenant may make payments under protest, reserving any rights it may
have to dispute the amount due.

|16.2 | CUMULATIVE REMEDIES. Except as expressly provided in this Lease, the specific remedies to which Landlord and Tenant may
resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other
remedies or means of redress which they may be lawfully entitled to seek in case of any breach or
threatened breach of any provisions of this Lease. In addition to the other remedies provided in
this Lease, Landlord shall be entitled to the restraint by injunction of the violation or attempted
or threatened violation of any of the covenants, conditions or provisions of this Lease or to seek
specific performance of any such covenants, conditions or provisions, provided, however, that the
foregoing shall not be construed as a confession of judgment by Tenant.

|16.3 | QUIET ENJOYMENT. This Lease is subject and subordinate to all matters of record. Landlord agrees that, upon Tenants
paying the Annual Fixed Rent, Additional Rent and other charges herein reserved, and performing and
observing the covenants, conditions and agreements hereof upon the part of Tenant to be performed
and observed, Tenant shall and may peaceably hold and enjoy the Premises during the term of this
Lease, without interruption or disturbance from Landlord or persons claiming through or under Landlord,
subject, however, to the terms of this Lease. This covenant shall be construed as running with the
land to and against subsequent owners and successors in interest, and is not, nor shall it operate
or be construed as, a personal covenant of Landlord, except to the extent of the Landlords
interest in the Building, and this covenant and any and all other covenants of Landlord contained
in this Lease shall be binding upon Landlord and upon such subsequent owners or successors in interest
of Landlords interest under this Lease, including ground or master lessees, to the extent of
their respective interests, as and when they shall acquire same and then only for so long as they
shall retain such interest.

|16.4 | SURRENDER. (A) No act or thing done by Landlord during the Lease Term shall be deemed an acceptance of
a surrender of the Premises, and no agreement to accept such surrender 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 of the Premises as an acceptance of a surrender of the Premises prior to the termination
of this Lease; provided, however, that the foregoing shall not apply to the delivery of keys to Landlord
or its agents in its (or their) capacity as managing agent or for purpose of emergency access. In

shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application
of such term or provision to persons or circumstances other than those as to which it is held invalid
or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall

|16.7 | PROVISIONS BINDING, ETC. The obligations of this Lease shall run with the land, and except as herein otherwise provided, the
terms hereof shall be binding upon and shall inure to the benefit of the successors and assigns,
respectively, of Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs,
executors, administrators, successors and assigns. Each term and each provision of this Lease to
be performed by Tenant shall be construed to be both a covenant and a condition. The reference contained
to successors and assigns of Tenant is not intended to constitute a consent to assignment by Tenant,
but has reference only to those instances in which Landlord may have later given consent to a particular
assignment as required by the provisions of Article XII hereof.

the request of the other, to execute a so-called Notice of Lease or short form lease in form recordable

under this Lease; and any such document shall expressly state that it is executed pursuant to the
provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease.

|16.12 | RIGHTS OF MORTGAGEE. This Lease shall be subject and subordinate to any mortgage now or hereafter on the Building (or
any part thereof), and to all renewals, modifications, consolidations, replacements and extensions
thereof and all substitutions therefor, provided that in the case of a future mortgage the holder
of such mortgage agrees to recognize the right of Tenant to use and occupy the Premises upon the
payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant
of Tenants obligations hereunder. In confirmation of such subordination and recognition, Tenant
shall execute and deliver promptly such instruments of subordination as such mortgagee may reasonably
request, subject to receipt of such instruments of recognition from such mortgagee as Tenant may
reasonably request. The form of Subordination, Nondisturbance and Attornment Agreement to be entered
into between Tenant and the holder of the mortgagee affecting the Building as of the Execution Date
of this Lease is attached hereto as Exhibit K. This Lease shall not be binding upon Tenant until
the holder of the mortgage which affects the Building as of the Execution Date executes such Subordination
Nondisturbance and Attornment Agreement. In the event that any mortgagee or its respective successor
in title shall succeed to the interest of Landlord, then this Lease shall nevertheless continue in
full force and effect and Tenant shall and does hereby agree to attorn to such mortgagee or successor
and to recognize such mortgagee or successor as its landlord. If any holder of a mortgage which includes
the Premises, executed and recorded prior to the Date of this Lease, shall so elect, this Lease,
and the rights of Tenant hereunder, shall be superior in right to the rights of such holder, with
the same force and effect as if this Lease had been executed, delivered and recorded, or a statutory
Notice hereof recorded, prior to the execution, delivery and recording of any such mortgage. The
election of any such holder shall become effective upon either notice from such holder to Tenant
in the same fashion as notices from Landlord to Tenant are to be given hereunder or by the recording
in the appropriate registry or recorders office of an instrument in which such holder subordinates
its rights under such mortgage to this Lease.

|16.14 | NOTICE TO MORTGAGEE AND GROUND LESSOR. After receiving notice from any person, firm or other entity that it holds a mortgage which includes
the Premises as part of the mortgaged premises, or that it is the ground lessor under a lease with
Landlord as ground lessee, which includes the Premises as a part of the leased premises, no notice
of default from Tenant to Landlord shall be effective unless and until a copy of the same is given
to such holder or ground lessor at the address as specified in said notice (as it may from time to
time be changed), and the curing of any of Landlords defaults by such holder or ground lessor
within a reasonable period of time after it has received notice of such default shall be treated
as performance by Landlord. For the purposes of this Section 16.14, the term mortgage
includes a mortgage on a leasehold interest of Landlord (but not one on Tenants leasehold interest).
If any mortgage is listed on Exhibit F then the same shall constitute notice from the holder of such
mortgage for the purposes of this Section 16.14.

| | (b) | That, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlords
obligations hereunder only upon foreclosure of such holders mortgage and the taking of possession
of the Premises, or, in the case of a ground lessor, the assumption of Landlords position hereunder
by such ground lessor. In no event shall the acquisition of title to the Building and the land on
which the same is located by a purchaser which, simultaneously therewith, leases the entire Building
or such land back to the seller thereof be treated as an assumption, by operation of law or otherwise,
of Landlords obligations hereunder, but Tenant shall look solely to such seller-lessee, and
its successors from time to time in title, for performance of Landlords obligations hereunder.
In any such event, this Lease shall be subject and subordinate to the lease to such purchaser provided
that such purchaser-lessor agrees to recognize the right of Tenant to use and occupy the Premises
in accordance with the terms of the Lease, subject to such

|-76-
|----



| |  | commercially reasonable terms as such purchaser-lessor may require, upon the payment of rent and all
other charges payable by Tenant under this Lease and the performance by Tenant of Tenants obligations
under this Lease. For all purposes, such seller-lessee, and its successors in title, shall be the
landlord hereunder unless and until Landlords position shall have been assumed by such purchaser-lessor.
Tenant acknowledges that it has been informed by Landlord that Landlord has entered into certain
agreements with its lenders (Lenders) which require it to include in this Lease (and
requires Tenant to include in any sublease which may be permitted hereunder) the following provisions: (i)
no rent payable under this Lease or under any such sublease may be based in whole or in part on the
income or profits derived from the Premises or any subleased premises except for percentage rent
based on gross (not net) receipts or sales; (ii) if Lenders succeed to the Landlords interests
under this Lease and are advised by Lenders counsel that all or any portion of the rent payable
under this Lease is or may be deemed to be unrelated business income within the meaning of the Internal
Revenue Code of the 1986, as amended, or the regulations issued thereunder, Lenders may elect to
amend unilaterally the calculation of rents under this Lease so that none of the rents payable to
Lenders under this Lease will constitute unrelated business income, provided that such amendment
will not increase the Tenants payment obligations or other liability under this Lease or reduce
the Landlords obligations under this Lease; and (iii) if Lenders request, Tenant will be obligated
to execute any document Lenders may deem necessary to effect the amendment of this Lease in accordance
with the foregoing subsection (ii). Further, no Annual Fixed Rent or Additional Rent may be paid
by Tenant more than thirty (30) days in advance except with Lenders prior written consent,
and any such payment without such consent shall not be binding on Lenders.

|16.16 | STATUS REPORT AND FINANCIAL STATEMENTS. Recognizing that Landlord and Tenant may find it necessary to establish to third parties, such as
accountants, banks, potential or existing mortgagees, potential purchasers or the like, the then
current status of performance hereunder, Landlord and Tenant, within ten (10) days after the request
of the other party (the Requesting Party) made from time to time, will furnish to the
Requesting Party, or any existing or potential holder of any mortgage encumbering the Premises, the
Building or the Prudential Center, or any potential purchaser of the Premises, the Building, or the
Prudential Center (each an Interested Party) a statement of the status of any matter
pertaining to this Lease, including, without limitation, acknowledgments that (or the extent to which)
each party is in compliance with its obligations under the terms of this Lease. In addition, Tenant
shall deliver to Landlord, or any Interested Party designated by Landlord, financial statements of
Tenant, and any guarantor of Tenants obligations under this Lease, as reasonably requested
by Landlord including, but not limited to, financial statements for the past two (2) years. If Tenant
or any guarantor is then a publicly traded entity, the financial statements of such entity on file
with the Securities and Exchange Commission or any successor agency shall be deemed to comply with
the requirements of this section. Any such status statement or financial statement delivered pursuant
to this Section 16.16 may be relied upon by any Interested Party. Any recipient of such financial
statements shall keep such information

requests Tenant to provide status or financial statements more than one time during any calendar
year, Landlord shall reimburse Tenant for its reasonable attorneys and accountants fees
incurred in connection with any subsequent request to provide status or financial statements during

| | (a)           Landlords Rights. If Tenant shall at any time fail to make any payment or perform any act which Tenant is obligated
to make or perform under this Lease and (except in the case of emergency) if the same continues unpaid
or unperformed beyond applicable grace periods, then Landlord may, but shall not be obligated so
to do, after ten (10) days notice to and demand upon Tenant, or without notice to or demand
upon Tenant in the case of any emergency, and without waiving, or releasing Tenant from, any obligations
of Tenant in this Lease contained, make such payment or perform such act which Tenant is obligated
to perform under this Lease in such manner and to such extent as may be reasonably necessary, and,
in exercising any such rights, pay any costs and expenses, employ counsel and incur and pay reasonable
attorneys fees. All sums so paid by Landlord and all reasonable and necessary costs and expenses
of Landlord incidental thereto, together with interest thereon from the date of demand at the annual
rate equal to the sum of (a) the Base Rate from time to time announced by Fleet National Bank, or
its successor as its Base Rate and (b) two percent (2%) (but in no event greater than the maximum
rate permitted by applicable law), shall be deemed to be Additional Rent and, except as otherwise
in this Lease expressly provided, shall be payable to the Landlord on demand, and if not promptly
paid shall be added to any rent then due or thereafter becoming due under this Lease, and Tenant
covenants to pay any such sum or sums with interest as aforesaid, and Landlord shall have (in addition
to any other right or remedy of Landlord) the same rights and remedies in the event of the non-payment
thereof by Tenant as in the case of default by Tenant in the payment of Annual Fixed Rent.

consent, if Landlord fails to cure such Landlord Default within the Landlord Cure Period, as hereinafter
defined, perform the same for the account of Landlord. Landlord shall, within thirty (30) days of
demand therefor, reimburse Tenant the sums so paid by Tenant in curing such Landlord Default. However,
except as set forth in Section 16.17(c), in no event shall Tenant have the right to offset against,
withhold or deduct from Annual Fixed Rent or Additional Rent payable under this Lease for any reason
relating to this Section 16.17(b). For the purposes of this Section 16.17(b), a Landlord Default

of such sale and apply the same, at its option against the expenses of the sale, the cost of moving
and storage, any arrears of rent or other charges payable hereunder by Tenant to Landlord and any
damages to which Landlord may be entitled under this Lease and at law and in equity.

Rent on or before the date (the Due Date) on which the same first becomes payable under
this Lease, the amount of such payment or installment shall bear interest from the Due Date through
and including the date such payment or installment is received by Landlord, at a rate equal to the
lesser of (i) the rate announced by Fleet National Bank (or its successor) from time to time as its
prime or base rate (or if such rate is no longer available, a comparable rate reasonably selected
by Landlord), plus two (2%) percent (Lease Interest Rate), or (ii) the maximum applicable
legal rate, if any. Notwithstanding the foregoing, interest shall not accrue with respect to the
first two late payments of Annual Fixed Rent or Additional Rent in any twelve month period, to the
extent that payment in full is made on or before the date five (5) business days after the Due Date
for such late payments. Such interest shall be deemed Additional Rent and shall be paid by Tenant

|16.24 | LANDLORD LIABILITY. Tenant shall neither assert nor seek to enforce any claim for breach of this Lease against any of
Landlords assets other than Landlords interest in the Building, and Tenant agrees to
look solely to such interest for the satisfaction of any liability of Landlord under this Lease,
it being specifically agreed that neither Landlord, nor any successor holder of Landlords interest
hereunder, nor any beneficiary of any Trust of which any person from time to time holding Landlords
interest is Trustee, nor any such Trustee, nor any member, manager, partner, director or stockholder
nor Landlords managing agent shall ever be personally liable for any such liability. This paragraph
shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord
or Landlords successors-in-interest, or to take any other action which shall not involve the
personal liability of Landlord, or of any successor holder of Landlords interest hereunder,
or of any beneficiary of any trust of which any person from time to time holding Landlords
interest is Trustee, or of any such Trustee, or of any manager, member, partner, director or stockholder
of Landlord or of Landlords managing agent, to respond in monetary damages from Landlords
assets other than

|      | Landlords interest in said Building, as aforesaid. In no event shall Landlord ever be liable
for any indirect or consequential damages or loss of profits or the like. Notwithstanding anything
to the contrary in the Lease contained, except for Landlords right to recover damages in accordance
with Section 16.18, neither Tenant nor Tenants agents or employees (or any of the officers,
trustees, directors, partners, beneficiaries, joint venturers, members, stockholders or other principals
or representatives and the like, disclosed or undisclosed, thereof) shall be liable to Landlord for
indirect or incidental damages, or lost profits of Landlord. In no event shall Tenant have the right
to terminate or cancel this Lease or to withhold rent or to set-off any claim or damages against
rent as a result of any default by Landlord or breach by Landlord of its covenants or any warranties
or promises hereunder, except as otherwise expressly provided in Section 7.6 of the Lease, or in
the case of a wrongful eviction of Tenant from the Premises (constructive or actual) by Landlord
continuing after notice to Landlord thereof and a reasonable opportunity for Landlord to cure the
same, or except as otherwise expressly set forth in this Lease. In the event that Landlord shall
be determined to have wrongfully withheld any consent or approval under this Lease, the sole recourse
and remedy of the Tenant in respect thereof shall be to specifically enforce Landlords obligation
to grant such consent or approval, and in no event shall the Landlord be responsible for any damages
of whatever nature in respect of its failure to give such consent or approval nor shall the same
otherwise affect the obligations of the Tenant under this Lease or act as any termination of this Lease.

| | (P) | In addition to complying with the applicable construction provisions of the Lease, Tenant shall not
install or operate Rooftop Installations in any portion of the Antenna Area until (x) Tenant shall
have obtained Landlords prior written approval, which approval will not be unreasonably withheld,
delayed or conditioned, of Tenants plans and specifications for the placement and installation
of the Rooftop Installations in the Premises, and (y) Tenant shall have obtained and delivered to
Landlord copies of all required governmental and quasi-governmental permits, approvals, licenses
and authorizations necessary for the lawful installation, operation and maintenance of the Rooftop
Installations. The parties hereby acknowledge and agree, by way of illustration and not limitation,
that Landlord shall have the right to withhold its approval of Tenants plans and specifications
hereunder, and shall not be deemed to be unreasonable in doing so, if Tenants intended placement
or method of installation or operation of the Rooftop Installations (i) may subject other licensees,
tenants or occupants of the Building, or other surrounding or neighboring landowners or their occupants,
to signal interference, Tenant hereby acknowledging that a shield may be required in order to prevent
such interference, (ii) does not minimize to the fullest extent practicable the obstruction of the
views from the windows of the Building that are adjacent to the Rooftop Installations, if any, (iii)
does not complement (in Landlords sole judgment, which shall not, however, require Tenant to
incur unreasonable expense) the design and finish of the Building, (iv) may damage the structural
integrity of the Building or the roof thereof, or (v) may constitute a violation of any consent,
approval, permit or authorization necessary for the lawful installation of the Rooftop Installations.

may wish to (and Landlord hereby reserves the right to at Landlords expense) install a central
Building system (the Central Building System) capable of, among other things, providing
Tenant with the type of service (to be) provided by Tenants Rooftop Installations. If Landlord
elects to install the Central Building System, and if Tenant, in its sole discretion, elects to participate
in such Central Building System, then: (w) Landlord shall reimburse Tenant for the unamortized
(i.e. on a straight-line basis over the useful life of the equipment in question based upon generally
accepted accounting principles) cost incurred by Tenant in installing the Rooftop Installations,
(x) Tenant shall, upon Landlords request and at Tenants expense, remove its Rooftop Installations
and other Alterations (including any existing cabling) from the Building and repair any damage caused
by their installation or removal, (y) Tenant may, at Tenants expense and subject to the provisions
of this Agreement (including, without limitation, subparagraph P hereof), have access to and use
(and tie into) the Central Building System for the uses permitted hereunder, and (z) commencing upon
Tenants use of the Central Building System and continuing thereafter so long as Tenant shall
utilize such Central Building System, Tenant shall pay as additional rent fees for the use of such
Central Building System reasonably designated by Landlord from time to time based upon Landlords
reasonable determination of the fair market value of the access rights to the Central Building System granted herein.

or replace the Central Building System, in accordance with the standards for the repair and maintenance
of such systems generally prevailing in the industry from time to time, so as to eliminate any material
interruption or other adverse effects caused by malfunction, damage or destruction of the Central
Building System, the cost of which shall be borne by Tenant if the problem was caused by the act
or omission of Tenant or its agents, contractors or employees. Notwithstanding the foregoing, Landlords
obligation to maintain, repair or replace the Central Building System shall apply only to the extent
necessary to reach premises in the Building that are then used by tenants after the malfunction,
damage or destruction or that, if damaged or destroyed, will be again used by tenants upon the completion
of restoration or repair thereof. In no event shall Tenant have any claim or right to make any claim
against Landlord whatsoever for any damages, including, without limitation, consequential or incidental
damages, or lost profits, in any such circumstance.

upon 95% of the Fair Market Rental Value, as defined in Section 5.4 of this Lease, of such Expansion
Area or such portion thereof, as of the Commencement Date in respect of such Expansion Area, or such
portion thereof. The fact that the Rent Commencement Date may not occur on the Commencement Date
with respect to an Expansion Area shall be taken into account in determining the Fair Market Rental
Value with respect to such Expansion Area. Landlord shall, within fifteen (15) days after written
request made by Tenant not earlier that the date sixty (60) days prior to the Notice Date with respect
to such Expansion Area, give Landlords designation of such Fair Market Rental Value to Tenant.
If Tenant timely and properly exercises its right to lease an Expansion Area, Tenant shall have the
right to submit any dispute as Landlords designation of such Fair Market Rental Value to arbitration
in accordance with Section 5.4 of the Lease. However, Tenant shall have no right to cancel its demise
of an Expansion Area after the determination of such Fair Market Rental Value.
