PREMISES

     2.1. Tenant leases the Premises from Landlord for the term and upon the conditions and
covenants set forth in this Lease. Tenant will have the non-exclusive right to use the common and
public areas of the Building and the Land. Except as may otherwise be expressly provided in this
Lease, the lease of the Premises does not include the right to use the roof, mechanical rooms,
electrical closets, janitorial closes, telephone rooms, parking areas or other non-common or
non-public areas of the Building.

ARTICLE 3

TERM

     3.1. All of the provisions of this Lease shall be in full force and effect from and after the
date first above written. The Lease Term shall commence on the Lease Commencement Date specified
in Section 3.2. If the Lease Commencement Date is not the first day of a month, then the Lease
Term shall be the period set forth in Section 1.3 plus the partial month in which the Lease
Commencement Date occurs. The Lease Term shall also include any properly exercised renewal or
extension of the term of this Lease.

4

 

     3.2. The “Lease Commencement Date” shall be the earlier of (a) February 1, 2006, or (b) the
date on which Tenant commences beneficial use of the Premises. Tenant shall be deemed to have
commenced beneficial use of the Premises when Tenant begins to conduct its business from any
portion of the Premises. Notwithstanding the foregoing, Tenant shall not have any right to
commence beneficial use of the Premises unless the same are vacant and delivered to Tenant by
Landlord and during any period Tenant is in breach of any of its obligations under this Lease.
Promptly after the Lease Commencement Date is ascertained, Landlord and Tenant shall execute the
certificate confirming the Lease Commencement Date attached to this Lease as Exhibit D. Failure to
execute said certificate shall not affect the commencement or expiration of the Lease Term.

     3.3. It is presently anticipated that the Premises will be delivered to Tenant on or about the
Anticipated Occupancy Date; provided, however, that if Landlord does not deliver possession of the
Premises by such date, Landlord shall not have any liability whatsoever, and this Lease shall not
be rendered void or voidable, as a result thereof.

     3.4. “Lease Year” shall mean a period of twelve (12) consecutive months commencing on the
Lease Commencement Date, and each successive twelve (12) month period thereafter; provided,
however, that if the Lease Commencement Date is on the first day of a month, then the second Lease
Year shall commence on the first day of the month in which the first anniversary of the Lease
Commencement Date occurs.

     3.5. Landlord hereby grants to Tenant the conditional right, exercisable at Tenant’s option,
to renew the term of this Lease for one (1) additional period of three (3) years (the “Renewal
Term”). If exercised, and if the conditions applicable thereto have been satisfied, the Renewal
Term shall commence immediately following the end of the initial Lease Term provided in Sections
1.3 and 3.1 of this Lease. The right of renewal therein granted to Tenant shall be subject to, and
shall be exercised in accordance with, the following terms and conditions:

          (a) Tenant shall exercise its right of renewal with respect to the Renewal Term by giving
Landlord written notice of such election not later than nine (9) months prior to the expiration of
the initial Lease Term. The Renewal Term shall be governed by all applicable provisions of this
Lease, including continuing annual escalations in Base Rent by the Base Rent Escalation Percentage
on the first (1st) day of the Renewal Term and on the first (1st) day of each
succeeding Lease Year, all in accordance with Section 4.1 and Tenant’s continue occupancy of the
Premises in its then “as is” condition.

          (b) If Tenant’s renewal notice if not given timely, then Tenant’s right of renewal shall lapse
and be of no further force or effect.

          (c) If Tenant is in default under this Lease on the date Tenant sends a renewal notice or any
time thereafter until the Renewal Term is to commence, then, at

5

 

Landlord’s election, the Renewal Term shall not commence and the term of this Lease shall
expire at the expiration of the initial term of this Lease.

          (d) If at any time any portion of the Premises has been subleased or assigned, or if this
Lease has been terminated with respect to any such portion, then Tenant’s rights pursuant to this
Section shall lapse and be of no further force or effect.

          (e) Tenant’s right of renewal under this Section may be exercised only by Tenant and may not
be exercised by or for the benefit of any transferee, sublessee or assignee of Tenant.

          (f) If Landlord provides notice to Tenant at any time prior to the end of the thirteenth
(13th) month prior to the end of the initial Lease Term that Landlord intends to expand
its business operations into the Premises during the period of the Renewal Term, then Tenant’s
right of renewal shall lapse and be of no further force or effect.

ARTICLE 4

BASE RENT

     4.1. (a) From and after the Lease Commencement Date, Tenant shall pay the Base Rent in equal
monthly installments in advance on the first day of each month during a Lease Year. On the first
day of the second and each succeeding Lease Year the Base Rent in effect shall be increased in the
following manner: (1) The Base Rent Annual Escalation Percentage (as defined in Section 1.6) shall
be multiplied by the Base Rent set forth in Section 1.5 above to arrive at the amount of the
increase in the Base Rent; (2) The amount determined in Step (1) above shall be added to the Base
Rent set forth in Section 1.5 above to arrive at the Base Rent payable for such Lease Year. Such
revised Base Rent shall thereafter be the Base Rent for all purposes, including without limitation,
calculating the increase in Base Rent for the succeeding year.

          (b) Promptly after the determination of an increase in the Base Rent pursuant to this Section,
Landlord shall submit to Tenant a statement setting forth the amount of such increase together with
Landlord’s calculation thereof.

     4.2. Concurrently with Tenant’s execution of this Lease, Tenant shall pay an amount equal to
one (1) monthly installment of the Base Rent payable during the first Lease Year, which amount
shall be credited toward the monthly installment of the Base Rent payable for the first full
calendar month of the Lease Term. If the Lease Commencement Date is not the first day of a month,
then the Base Rent from the Lease Commencement Date until the first day of the following month
shall be prorated on a per diem basis at the rate of one-thirtieth (1/30th) of the
monthly installment of the Base Rent payable during the first Lease Year, and Tenant shall pay such
prorated installment of the Base Rent on the Lease Commencement Date.

6

 

     4.3. All sums payable by Tenant under this Lease, whether or not stated to be Base Rent,
additional rent or otherwise, shall be paid to Landlord in legal tender of the United States,
without setoff, deduction or demand, at the Landlord Payment Address, or to such other party or
such other address as Landlord may designate in writing. Landlord’s acceptance of rent after it
shall have become due and payable shall not excuse a delay upon any subsequent occasion or
constitute a waiver of any of Landlord’s rights hereunder. If any sum payable by Tenant under this
Lease is paid by check which is returned due to insufficient funds, stop payment order, or
otherwise, then: (a) such event shall be treated as a failure to pay such sum when due; and (b) in
addition to all other rights and remedies of Landlord hereunder, Landlord shall be entitled (i) to
impose a returned check charge of One Hundred Dollars ($100.00) to cover Landlord’s administrative
expenses and overhead for processing, and (ii) to require that all future payments be remitted by
wire transfer, money order, or cashier’s or certified check.

     4.4. Landlord and Tenant agree that no rental or other payment for the use of occupancy of the
Premises is or shall be based in whole or in part on the net income or profits derived by any
person or entity from the Building or the Premises. Tenant further agrees that it will not enter
into any sublease, license, concession or other agreement for any use or occupancy of the Premises
which provides for a rental or other payment for such use or occupancy based in whole or in part on
the net income or profits derived by any person or entity from the Premises so leased, used or
occupied. Nothing in the foregoing sentence, however, shall be construed as permitting or
constituting Landlord’s approval of any sublease, license, concession or other use or occupancy
agreement not otherwise approved by Landlord in accordance with the provisions of Article VII.

ARTICLE 5

INCREASES IN OPERATING CHARGES AND REAL ESTATE TAXES

     5.1. Landlord hereby agrees to operate and maintain the common areas and the Building in a
manner substantially similar to that of similar class office buildings in the Westfields submarket
in Chantilly, Virginia.

     5.2. (a) From and after the first (1st) day of the second (2nd) Lease
Year, Tenant shall pay an additional rent Tenant’s Proportionate Share of the amount by which
Operating Charges for each calendar year falling entirely or partly within the Lease Term exceed a
base amount (the “Operating Charges Base Amount”) equal to the Operating Charges incurred during
the Operating Charges Base Year. Tenant’s Proportionate Share with respect to Operating Charges
set forth in Article 1 has been calculated to be that percentage which is equal to a fraction, the
numerator of which is the number of square feet of rentable area in the Premises, and the
denominator of which is the number of square feet of total rentable area from time to time in the
Building (excluding any below-grade storage, roof and parking area). Tenant’s Proportionate Share
is subject to adjustment by Landlord during the Lease Term due to permitted expansions of
contractions of the Premises or changes in the layout or configuration of or standards for the
Building.

7

 

          (b) “Operating Charges” shall mean the sum of the following expenses incurred by Landlord in
the ownership and operation of the Building: (1) electricity, gas, water, HVAC, sewer and other
utility charges of every type and nature; (2) premiums, deductibles and other charges for
insurance; (3) management fees and personnel costs of the Building; (4) costs of service, access
and maintenance contracts relating to the Building as a whole; (5) maintenance, repair and
replacement expenses and supplies which are deducted by Landlord in computing its federal income
tax liability; (6) depreciation for capital expenditures made by Landlord to reduce operating
expenses if Landlord reasonably estimates that the annual reduction in operating expenses shall
exceed such depreciation or to comply with legal or insurance requirements applicable after the
date hereof; (7) charges for janitorial and cleaning services and supplies furnished to the
Building; (8) any business, professional or occupational license tax payable by Landlord with
respect to the Building; (9) reasonable serves for replacements, repairs and contingencies; (10)
sales, use and personal property taxes payable in connection with tangible personal property and
services purchased for the Building; (11) accounting fees relating to the determination of
Operating Expenses (and tenants’ proportionate shares thereof) and the preparation of statements
required by tenant leases; (12) expenses incurred in connection with concierge services provided to
the Building (if any) special assessments, fees, penalties and other charges and costs for transit,
transit encouragement traffic reduction programs, or any similar purposes; and (13) any other
expense incurred by Landlord in maintaining, repairing or operating the Building. Operating
Charges shall not include: (i) principal or interest payments on any Mortgages (as defined in
Section 21.1); (ii) leasing commission or legal fees with respect to the negotiation of leases;
(iii) depreciation for capital expenditures, except as specified above; (iv) the costs of special
services and utilities separately charged to particular tenants of the Building; and (v) the cost
of any improvement, alteration, addition, change, replacement equipment, extraordinary repair, and
other item which under generally accepted accounting principles (“GAAP”) is properly classified as
a capital expenditure, except (A) capital expenses required by any law taking effect after the date
hereof and which the Building does not comply and (B) capital expenses pursuant to (6) above, in
all of which cases the costs thereof shall be included in operating expenses for the calendar year
in which the costs are incurred and subsequent calendar years on a straight line basis amortized
over the useful life thereof as determined by GAAP with an interest factor equal to the “prime
rate” (as published in the Money Rates section the Wall Street Journal) at the time of Landlord’s
having actually incurred said expenditure.

          (c) If the average occupancy rate for the Building during any calendar year (including the
Operating Charges Base Year) is less than one hundred percent (100%), or if any tenant is
separately paying for (or does not require) electricity or janitorial services furnished to its
premises, then Landlord may include in Operating Charges for such year additional expenses, as
reasonably estimated by Landlord, which would have been incurred during such year if such average
occupancy rate had been one hundred percent (100%) and if Landlord paid for electricity and
janitorial services furnished to such premises. In no event shall the provisions of this
subsection be used to enable Landlord to collect from the tenants of the Building ore than one
hundred percent (100%) of Operating Charges [it being understood that for the purposes hereof
Landlord

8

 

shall be deemed to have paid and collected from Landlord a proportionate share of Operating
Charges consistent with the terms of this Lease with respect to portions of the Building occupied
by Landlord].

          (d) From and after the first (1st) day of the second (2nd) Lease Year,
Tenant shall make estimated monthly payments to Landlord on account of the amount by which
Operating Charges that are expected to be incurred during each calendar year (or portion thereof)
would exceed the Operating Charges Base Amount. At the beginning of the Lease Term and at the
beginning of each calendar year thereafter, Landlord may submit a statement setting forth
Landlord’s reasonable estimate of such excess and Tenant’s Proportionate Share thereof. Tenant
shall pay to Landlord on the first day of each month following receipt of such statement, until
Tenant’s receipt of the succeeding annual statement, an amount equal to one-twelfth (1/2) of each
such share (estimated on an annual basis without proration pursuant to Section 5.4). From time to
time during any calendar year, Landlord may revise Landlord’s estimate and adjust Tenant’s monthly
payments to reflect Landlord’s revised estimate. Within approximately one hundred twenty (120)
days after the end of each calendar year, or as soon thereafter as is feasible, Landlord shall
submit a statement showing (1) Tenant’s Proportionate Share of the amount by which Operating
Charges incurred during the preceding calendar year exceeded the Operating Charges Base Amount, (2)
the aggregate amount of Tenant’s estimated payments made on account of Operating Charges during
such year. If such statement indicates that the aggregate amount of such estimated payments
exceeds Tenant’s actual liability, then Landlord shall credit the net overpayment toward Tenant’s
next estimated payment(s) pursuant to this Section, or, with respect to overpayments in the
calendar year during which the Lease Term expires, Landlord shall refund to Tenant the net
overpayment. If such statement indicates that Tenant’s actual liability exceeds the aggregate
amount of such estimated payments, then Tenant shall pay the amount of such excess as additional
rent within ten (10) days of Tenant’s receipt of such statement.

     5.3. (a) From and after the first (1st) day of the second (2nd) Lease
Year, Tenant shall pay as additional rent Tenant’s Proportionate Share of the amount by which Real
Estate Taxes for each calendar year falling entirely or partly within the Lease Term exceed a base
amount (the “Real Estate Taxes Base Amount”) equal to the Real Estate Taxes incurred during the
Real Estate Taxes Base Year. Tenant’s Proportionate Share with respect to Real Estate Taxes shall
be that percentage which is equal to a fraction, the numerator of which is the number of square
feet of rentable area in the Premises, and the denominator of which is the number of square feet of
total rentable area from time to time in the Building (excluding any roof and parking area).

          (b) “Real Estate Taxes” shall mean (1) all real estate taxes, vault and/or public space
rentals, rates and assessments (including general and special assessments, if any), ordinary and
extraordinary, foreseen and unforeseen, which are imposed upon Landlord or assessed against the
Building or the Land or Landlord’s personal property used in connection therewith, (2) any other
present or future taxes or governmental charges that are imposed upon Landlord or assessed against
the Building or the Land which are in the nature of or in substitution for real estate taxes,
including any

9

 

tax levied on or measured by the gross rents payable by tenants ;of the Building and any
transit tax and any assessment imposed in connection with business improvements or similar
districts, and (3) reasonable expenses (including, without limitation, attorneys’ and consultants’
fees and court costs) incurred in reviewing, protesting or seeking a reduction or abatement of, or
otherwise defending or participating in any challenge to real estate taxes, whether or not such
protest or reduction is ultimately successful. Tenant shall not initiate or participate in any
contest of Real Estate Taxes without Landlord’s prior written consent. Subject to the foregoing,
Real Estate Taxes shall not include any inheritance, succession, estate, gift, franchise,
corporation, net income or net profits tax assessed against Landlord from the operation of the
Building, nor shall Real Estate Taxes include any transfer or excise taxes or taxes, or provided
Tenant has timely paid Tenant’s Proportionate Share of Real Estate Taxes, any interest or penalties
incurred as a result of Landlord’s failure to timely pay Real Estate Taxes (except for penalties on
Real Estate Taxes which Landlord has not paid as a result of a bona fide contest) provided,
however, that if the taxing authority permits a taxpayer to elect to pay in installments, then, for
purposes of determining the amount of Real Estate Taxes, if Landlord so elects to pay in
installments, all interest charges in connection therewith shall be deemed Real Estate Taxes.
Notwithstanding any provisions to the contrary, in no event shall Real Estate Taxes include any tax
or assessment attributable to any period occurring prior to the Lease Commencement Date or
subsequent to the expiration or sooner termination of this Lease.

          (c) If during any calendar year (including the Real Estate Taxes Base Year) the Building is
not fully assessed for tax purposes, then Landlord may include in Real estate Taxes for such year
all additional taxes, as reasonably estimated by Landlord, which would have been incurred during
such year if the Building had been fully assessed; provided, however, that in no event shall
Landlord be entitled to collect from tenants on account of Real Estate Taxes in any calendar year
(including the Real Estate Taxes Base Year) more than one hundred percent (100%) of the actual Real
Estate Taxes payable by Landlord with respect to such calendar year [it being understood that for
the purposes hereof Landlord shall be deemed to have paid an collected from Landlord a
proportionate share of Operating Charges consistent with the terms of this Lease with respect to
portions of the Building occupied by Landlord].

          (d) From an dafter the first (1st) day of the second (2nd) Lease Year,
Tenant shall make estimated monthly payments to Landlord on account of the amount by which Real
Estate Taxes that are expected to be incurred during each calendar year would exceed the Real
Estate Taxes Base Amount. At the beginning of the Lease Term and at the beginning of each calendar
year thereafter, Landlord may submit a statement setting forth Landlord’s reasonable estimate of
such amount and Tenant’s Proportionate Share thereof. Tenant shall pay to Landlord on the first
day of each month following receipt of such statement, until Tenant’s receipt of the succeeding
annual statement, an amount equal to one-twelfth (1/12) of such share (estimated on an annual basis
without proration pursuant to Section 5.4). From time to time during any calendar year, Landlord
may revise Landlord’s estimate and adjust Tenant’s monthly payments to reflect Landlord’s revised
estimate. Within approximately one hundred twenty (120) days after the end of

10

 

each calendar year, or as soon thereafter as is feasible, Landlord shall submit a statement
showing (1) Tenant’s Proportionate Share of the amount by which Real Estate Taxes incurred during
the preceding calendar year exceeded the Real Estate Taxes Base Amount, and (2) the aggregate
amount of Tenant’s estimated payments made during such year. If such statement indicates that the
aggregate amount of such estimated payments exceeds Tenant’s actual liability, then Landlord shall
credit the net overpayment toward Tenant’s next estimated payment(s) pursuant to this Section, or,
with respect to the overpayments in the calendar year during which the Lease Term expires, Landlord
shall refund to tenant the net overpayment. If such statement indicates that Tenant’s actual
liability exceeds the aggregate amount of such estimated payments, then Tenant shall pay the amount
of such excess as additional rent within ten (10) days of Tenant’s receipt of such statement.

     5.4. If the Lease Term commences or expires on a day other than the first day or the last day
of a calendar year, respectively, then Tenant’s liabilities pursuant to this Article for such
calendar year shall be apportioned by multiplying the respective amount of Tenant’s Proportionate
Share thereof for the full calendar year by a fraction, the numerator of which is the number of
days during such calendar year falling within the Lease Term, and the denominator of which is three
hundred sixty-five (365).

ARTICLE 6

non-governmental) office purposes compatible with first class office buildings in the jurisdiction
in which the Building is located, and for no other use or purpose. Tenant shall not use or occupy
the Premises for any unlawful purpose, or in any manner that will violate the certificate of
occupancy for the Premises or the Building or that will constitute waste, nuisance or unreasonable
annoyance to Landlord or any other tenant or use of the Building, or in any manner that will
increase the number of parking spaces required for the Building or its full occupancy as required
by law. Tenant shall comply with all present and future laws (including, without limitation, the

“Laws”) concerning the use, occupancy and condition of the Premises and all machinery, equipment,
furnishings, fixtures and improvements therein; all of which shall be complied with in a timely
manner at Tenant’s sole expense. Notwithstanding the foregoing, but subject to Section 6.4,
Landlord at its expense (subject to reimbursement pursuant to article V, if and to the extent
permitted thereby) shall take steps necessary to comply with Laws to the extent the same applies
directly to the Building structure and systems and the common areas of the Building as a whole;
provided, however, that to the extent any non-compliance is a result of the use or occupancy of the
Premises or any action or inaction of Tenant, or if any improvements made by Landlord to comply
with such Laws benefit solely the Premises, then such

11

 

compliance shall be at Tenant’s cost; and provided further, however, that Tenant at its
expense shall be responsible for all space within the Premises being in compliance with such Laws.
If any such Law requires a occupancy or use permit or license for the Premises or the operation of
the business conducted therein, then Tenant shall obtain and keep current such permit or license at
Tenant’s expense and shall promptly deliver a copy thereof to Landlord. Without limiting the
generality of the foregoing, Tenant, at its expense, shall install and maintain fire extinguishers
and other fire protection devices as may be required from time to time by any agency having
jurisdiction thereof and/or the underwriters insuring the Building. Use of the Premises is subject
to all covenants, conditions and restrictions of record. Tenant shall not use any space in the
Building for the sale of goods to the public at large or for the sale at auction of goods or
property of any kind. Tenant shall not conduct any operations, sales, promotions, advertising or
special events outside the Premises either in the Building or on the Land.

     6.2. Tenant shall pay before delinquency any business, rent or other taxes or fees that are
now or hereafter levied, assessed or imposed upon Tenant’s use or occupancy of the Premises, the
conduct of Tenant’s business at the Premises, or Tenant’s equipment, fixtures, furnishings,
inventory or personal property. If any such tax or fee is enacted or altered so that such tax is
levied against Landlord or so that Landlord is responsible for collection or payment thereof, then
Tenant shall pay as additional rent the amount of such tax or fee.

     6.3. Tenant shall not cause or permit any Hazardous Materials to be generated, used, treated,
released, stored or disposed of in or about the Building or the Land, provided that Tenant may use
and store normal and reasonable quantities of standard cleaning and office materials as may be
reasonably necessary for Tenant to conduct normal general office use operations in the Premises so
long as same is properly, safely and lawfully stored and used by Tenant, and the quantity of same
does not equal or exceed a “reportable quantity” as defined in 40 C.F.R. 302 and 305, as amended.
At the expiration or earlier termination of this Lease, Tenant shall surrender the Premises to
Landlord free of Hazardous Materials and in compliance with all Environmental Laws. “Hazardous

shall: (i) give Landlord immediate verbal and follow-up written notice of any actual or threatened
Environmental Laws and to the satisfaction of Landlord and only after Tenant has obtained
Landlord’s prior written consent, which shall not be unreasonably withheld, and (ii) promptly
deliver to Landlord copies of any notices or other items received from or submitted to any
governmental or quasi-governmental agency, or any claim instituted or threatened by any third
party, concerning the Premises, the occupancy or use thereof, or the existence or potential
existence of Hazardous Materials therein. Upon any Environmental Default, in addition to all other
rights available to Landlord under this Lease, at law or in equity, Landlord shall have the right
but not the obligation to immediately enter the Premises, to supervise and approve any actions
taken by Tenant to address the Environmental Default, and, if Tenant fails to immediately address
same to Landlord’s satisfaction, to perform, at Tenant’s sole cost and expense, any lawful action

     6.4. Landlord at its expense (subject to reimbursement pursuant to Article V to the extent
permitted thereby) shall take steps necessary to comply with Title III of the ADA to the extent
same applies directly to the common areas of the Building s a whole; provided, however, that to the
extent any non-compliance is a result of the use or occupancy of the Premises or any action or
inaction of Tenant or any Agent, or if any improvements made by Landlord to comply with the ADA
benefit solely the Premises, then such compliance shall be at Tenant’s cost. Tenant at its sole
cost and expense shall be solely responsible for taking any and all measures which are required to
comply with the ADA concerning the Premises (including suite entry doors and related items) and the
business conducted therein. Any Alterations (as defined in Section 91.) made or constructed by
Tenant for the purpose of complying with the ADA or which otherwise require compliance with the ADA
shall be done in accordance with this Lease: provided, that Landlord’s consent to such Alterations
shall not constitute either Landlord’s assumption, in whole or in part, of Tenant’s responsibility
for compliance with the ADA, or representation or confirmation by Landlord that such Alterations
comply with the provisions of the ADA. Tenant shall indemnify, defend (with counsel approved by
Landlord) and hold Landlord and Landlord’s Representatives harmless from and against any and all
claims, judgments, damages (including indirect and consequential damages), penalties, fines,

improvements to be made to the common areas of the Building to comply with the ADA, and such
improvements solely benefit the Premises, then Tenant shall reimburse Landlord for all costs and
expenses incurred by Landlord in connection with the performance of such improvements.

ARTICLE 7

ASSIGNMENT AND SUBLETTING

     7.1 Tenant shall not assign, transfer or otherwise encumber (collectively, “assign”) this
Lease or all or any of Tenant’s rights hereunder or interest herein, or sublet or permit anyone to
use or occupy (collectively, “sublet”) the Premises or any part thereof, without obtaining the
prior written consent of Landlord, which consent shall not be unreasonably withheld. Landlord and
Tenant hereby agree that it shall be reasonable under this Lease for Landlord to withhold consent
to any assignment of Tenant’s interest in this Lease or a sublease of any portion of the Premises
if one or more of the following apply, provided that he following shall not limit other reasonable
grounds for withholding consent: (a) the assignee or subtenant intends to use the Proposed Sublet
(hereinafter defined) for purposes which are not permitted under this Lease or not in keeping with
the character of a Class A building in the Westfields submarket, or the assignee or subtenant is
not a reasonably experienced and reputable operator of the business the assignee or subtenant plans
to operate: (b) the assignee or subtenant is either a governmental authority or any other person
enjoying sovereign or diplomatic immunity; (c) the proposed sublease or assignment may cause
Landlord to be in violation of another lease

14

 

or agreement to which Landlord is a party, or may give another tenant of the Building a right to
cancel its lease or to reduce its obligations for its lease; (d) the assignee or subtenant is not a
party of reasonable financial worth and/or financial stability in light of the responsibilities
involved under this Lease with respect to an assignment or under the proposed sublease with respect
to a sublease, as of the date Landlord’s consent is requested: (c) either the assignee or
subtenant, or any person which directly or indirectly controls, is controlled, by, or is under
common control with, the assignee or subtenant, (i) leases or occupies space in the Building upon
the date Landlord receives Tenant’s Request Notice (hereinafter defined), or at any time thereafter
until the Landlord’s consent is granted, or (ii) is negotiating with landlord to lease space in the
Building at such time. No assignment or right of occupancy hereunder may be effectuated by
operation of law or otherwise without the prior written consent of Landlord. Any assignment or
subletting, Landlord’s consent thereto, the listing or posting of any name other than Tenant’s, or
Landlord’s collection or acceptance of rent from any assignee or subtenant shall not be construed
either as waiving or releasing Tenant from any of its liabilities or obligations under this Lease
as a principal and not as a guarantor or surety, or as relieving Tenant or any assignee or
subletting. As security for this Lease, Tenant hereby assigns to Landlord the rent due from any
assignee or subtenant or Tenant. For any period during which Tenant is in default hereunder,
Tenant hereby authorizes each such assignee or subtenant to pay said rent directly to landlord upon
receipt of notice from landlord specifying same. Landlord’s collection of such rent shall not be
construed as an acceptance of such assignee or subtenant as a tenant. Tenant shall not mortgage,
pledge, hypothecate or encumber (collectively “mortgage”) this Lease without Landlord’s prior
written consent, which consent may be granted or withheld in Landlord’s sole and absolute
discretion. Tenant shall pay to Landlord an administrative fee equal to five hundred dollars
($500) plus all other expenses (including attorneys’ fees and accounting costs) incurred by
Landlord in connection with Tenant’s request for Landlord to give its consent to any assignment,
subletting, or mortgage, and Landlord’s receipt of such sum shall be a condition to Landlord
providing such consent. Tenant shall notify landlord prior to engaging a real estate broker in
connection with any proposed assignment or sublease. Any sublease, assignment or mortgage shall at
landlord’s option, be effected on forms approved by Landlord. Tenant shall deliver to Landlord a
fully-executed copy of each agreement evidencing a sublease, assignment or mortgage, and any
document required by Landlord in connection with its consent thereto, within ten (1) days after
execution thereof.

     7.2. If Tenant is a partnership, then any event (whether voluntary, concurrent or related)
resulting in a dissolution of Tenant, any withdrawal or change (whether voluntary, involuntary or
by operation of law) of partners owning a controlling interest in Tenant (including each general
partner), or any structural or other change having the effect of limiting the liability lf the
partners shall be deemed a prohibited assignment of this Lease subject to the provisions of this
Article. If Tenant is a corporation or a partnership with a corporate general partner, then any
event (whether voluntary, concurrent or related) resulting in a dissolution, merger, consolidation
or other reorganization of Tenant (or such corporate general partner), or the sale or transfer or
relinquishment of the interest of shareholders who as of the date of this Lease, own a

15

 

controlling interest of the capital stock of Tenant (or such corporate general partner), shall be
deemed a prohibited assignment of this Lease subject to the provisions of this Article; provided,
however, that if Tenant is a corporation whose stock is traded through a national or regional
exchange or over-the-counter market, then the foregoing portion f this sentence shall be applicable
only if such event has or is intended to have the effect of limiting liability under this Lease.
Notwithstanding anything contained in this Article VII to the contrary, provided Tenant is not in
default hereunder, Tenant may, upon not less than ten (10) days’ prior written notice to Landlord
(which notice shall contain a written certified from Tenant, signed by an authorized representative
of Tenant, containing a representation as to the true, correct and complete legal and beneficial
relationship of Tenant and the proposed assignee, transferee or subtenant), but without Landlord’s
prior written consent and without being subject to Landlord’s rights and Tenant’s obligations set
forth in Section s7.4 and 7.5 below, assign or transfer its entire interest in this Lease or
sublease the entire Premises to any of the following (each, an “Affiliate”): (a) to a corporation
or other business entity (herein sometimes referred to as a “successor corporation”) into or with
which Tenant shall be merged or consolidated, or to which substantially all of the assets of Tenant
may be transferred or sold, provided that such successor corporation shall have a net worth and
liquidity factor at least equal to the net worth and liquidity factor of Tenant as of the date
hereof or the date immediately before such transfer whichever is greater, and provided that the
successor corporation shall assume in writing all of the obligations and liabilities of Tenant
under this Lease and the proposed use of the Premises is in compliance with Article VI; or (b) to a
corporation or other business entity (herein sometimes referred to as a “related corporation”)
which shall control, be controlled by or be under common control with Tenant, provided that such
related corporation shall have a net worth and liquidity factor at least equal to the net worth and
liquidity factor of Tenant as of the date hereof or the date immediately before such transfer,
whichever is greater, and provided that the related corporation shall assume in writing all of the
obligations and liabilities of Tenant under this Lease (without relieving Tenant therefrom) and the
proposed use of the Premises is in compliance with Article VI. In the event of any such assignment
or subletting, Tenant shall remain fully liable as a primary obligor for the payment of all rent
and other charges required hereunder and for the performance of all obligations to be performed by
Tenant hereunder. For purposes of clause (b) above, “control” shall be deemed to be ownership of
more than fifty (50%) of the stock or other voting interest of the controlled corporation or other
business entity. Notwithstanding the foregoing, if Tenant structures an assignment or sublease to
an entity that meets the definition f an Affiliate as specified above for the purpose of
circumventing the restrictions on subleases and assignments provided elsewhere in this Article VII,
then such subtenant or assignee shall conclusively be deemed not to be an Affiliate and subject to
all such restrictions. Additionally, nothing in this Article VII shall limit or prohibit the
initial public offering or subsequent trading of Tenant’s stock on a recognized securities exchange
or market, or any change in stock ownership or control resulting therefrom.

     7.3. If any time during the Lease Term Tenant desires to assign, sublet or mortgage all or
part of this Lease or the Premises, then in connection with Tenant’s request to Landlord for
Landlord’s consent thereto. Tenant shall give notice to Landlord

16

 

in writing (“Tenant’s Request Notice”) containing: the identity of the proposed assignee,
subtenant or other party and a description of its business; the terms of the proposed assignment,
subletting or other transaction (including a copy of the proposed document for same); the
commencement date of the proposed assignment, subletting or other transaction (the “Proposed
Sublease Commencement Date”); the area proposed to be assigned, sublet or otherwise encumbered (the
“Proposed Sublet Space”); the most recent financial statement or other evidence of financial
responsibility of such proposed assignee, subtenant or other party; and a certification executed by
Tenant and such party stating whether or not any premium or other consideration is being paid for
the assignment, sublease or other transaction.

     7.4. Landlord shall have the right in its sole and absolute discretion to terminate this Lease
with respect to the Proposed Sublet Space by sending Tenant written notice of such termination
within thirty (30) days after Landlord’s receipt of Tenant’s Request Notice. If the Proposed
Sublet Space does not constitute the entire Premises and Landlord exercises its option to terminate
this Lease with respect to the Proposed Sublet Space, then (a) Tenant shall tender the Proposed
Sublet Space to Landlord on the Proposed Sublease Commencement Date and such space shall thereafter
be deleted from the Premises, and (b) as to the portion of the Premises which is not part of the
Proposed Sublet Space, this Lease shall remain in full force and effect except that Base Rent and
additional rent shall be reduced pro rata. Fifty percent (50%) of the cost of any construction
required to permit the operation of the Proposed Sublet Space separate from the balance of the
Premises shall be paid by Tenant to landlord as additional rent hereunder. If the Proposed Sublet
Space constitutes the entire Premises and Landlord elects to terminate this Lease, then Tenant
shall tender the Proposed Sublet Space to Landlord, and this Lease shall terminate, on the Proposed
Sublease Commencement Date.

     7.5. If any sublease or assignment (whether by operation of law or otherwise, including
without limitation an assignment pursuant to the provisions of the Bankruptcy Code or any other
insolvency Law) provides that the subtenant or assignee there under is to pay any amount in excess
of the rental and other charges due this Lease, then whether such excess be in the form of an
increased monthly or annual rental, a lump sum payment, payment for the sale, transfer or lease of
Tenant’s fixtures, leasehold improvements, furniture and other personal property (and if the
subleased or assigned space does not constitute the entire Premises, the existence of such excess
shall be determined on a pro-rata basis). Tenant shall pay to Landlord fifty percent (50%) of any
such excess or other premium applicable to the sublease or assignment, which amount shall be paid
by Tenant to Landlord as additional rent upon such terms as shall be specified by Landlord and in
no event later than ten (10) days after any receipt thereof by Tenant (it being understood that
Landlord is not intending to receive any amounts which are considered to be based on net income or
profits of Tenant or any subtenant or assignee). Except as otherwise provided in Section 7.2 in
connection with an assignment, transfer, or sublease to Affiliate or related corporation, if an
assignment is deemed to have occurred pursuant to Section 7.2. then for purposes of this Section
the rent payable by the assignee shall be deemed to be increased to the then fair market rent for
the Premises as reasonably determined by Landlord. Acceptance by landlord of any

17

 

payments due under this Section shall not be deemed to constitute approval by landlord of any
sublease or assignment, not shall such acceptance waive any rights of Landlord hereunder. Landlord
shall have the right to inspect and audit Tenant’s books and records relating to any sublease or
assignment.

     7.6. All restrictions and obligations imposed pursuant to this Lease on Tenant shall be deemed
to extend to any subtenant, assignee, licensee, concessionaire or other occupant or transferee, and
Tenant shall cause such person to comply with such restrictions and obligations. Any assignee
shall be deemed to have assumed obligations as if such assignee had originally executed this Lease
and at Landlord’s request shall execute promptly a document confirming such assumption. Each
sublease is subject to the condition that if the Lease Term is terminated or Landlord succeeds to
Tenant’s interest in the Premises by voluntary surrender or otherwise, at Landlord’s option the
subtenant shall be bound to Landlord for the balance of the term of such sublease and shall attorn
to and recognize Landlord as its landlord under the then executory terms of such sublease.

ARTICLE 8

     8.1. Tenant, at Tenant’s sole cost and expense, shall promptly make all repairs, perform all

provide the labor involved for such replacement at no cost to Tenant. If any lien (or a petition
to establish such lien) is filed in connection with Tenant’s fulfillment of its obligations under
this Section, such lien (or petition) shall be discharged by tenant within ten (10) days thereafter
at Tenant’s sole cost and expense, by the payment thereof or the filing of a bond acceptable to
Landlord.

ARTICLE 9

ALTERATIONS

     9.1 Tenant shall accept the Premises in its “as is” condition as of the date possession of the
Premises is delivered to Tenant. The initial improvement of the Premises under this Lease, if any,
shall be accomplished by Tenant or its designated contractor in accordance with all applicable

agreements under this Lease. Landlord shall not be required to maintain such security deposit in a

incurred, by reason of Tenant’s default (including, but not limited to, any damage or deficiency
arising in connection with the reletting of the Premises). If any portion of the security deposit
is so used or applied, then within three (3) business days after landlord gives written notice to
Tenant of such use or application, Tenant shall deposit with Landlord cash in an amount sufficient
to restore the security deposit to the original Security Deposit Amount, and Tenant’s failure to do
so shall constitute an Event of Default under this Lease.

     11.2. If Landlord transfers the security deposit to any purchaser or other transferee of
Landlord’s interest in the Building or the Land, then Tenant shall look only to such purchaser or
transferee for the return of the security deposit. Tenant acknowledges that the holder of any
Mortgage shall not be liable for the return of any security deposit made by Tenant hereunder unless
such holder actually receives such security deposit. Tenant shall not pledge, mortgage, assign or
transfer the Security Deposit or any interest therein.

Lease Term be reduced to the sum of Fifty-Six Thousand One Hundred Twenty-Five and 50/100 Dollars
($56,125.50) upon written notice to Landlord. If all of the aforesaid conditions are met for such
Adjustment Year, landlord shall so reduce the amount of the Security Deposit by refunding to Tenant

Tenant’s electricity consumption is excessive, then Landlord may install at Tenant’s expense
submeters to ascertain Tenant’s actual electricity consumption, and Tenant shall thereafter pay for
such consumption at the then-current price per kilowatt hour charged Landlord by the utility.
Tenant’s electricity consumption shall be deemed excessive if the electricity consumption in the

consumption per square foot of rentable area during the same period for typical similarly situated
tenants in the Building, as reasonably calculated by Landlord.

     14.3. Tenant shall reimburse Landlord for the cost, of any excess water, sewer and chiller

terminate this Lease or receive a rent abatement, in the event of Landlord’s failure or inability
to furnish any of the utilities or services required to be furnished by Landlord hereunder.

of a claim of constructive eviction, then Tenant shall give Landlord written notice thereof and a
reasonable opportunity evicted or is entitled to a rent abatement. Ay property placed by Tenant or
any Agent in or about the Premises or the Building shall be at the sole risk of Tenant, and
Landlord shall not in any manner be held responsible therefore. Any person receiving an article
delivered for Tenant shall be acting as Tenant’s agent for such purpose and not as Landlord’s
agent. For purposes of this Article, the term “Building” shall be deemed to include the Land.
Notwithstanding the foregoing provisions of this Section, Landlord shall not be released from
liability to Tenant for any physical injury to any natural person or any damage to Tenant’s
property caused by Landlord’s willful misconduct or gross negligence to the extent such injury or
damage is not covered by insurance either carried by Tenant (or such person) or required by this
Lease to be carried by Tenant; provided, however, that neither Landlord nor any of Landlord’s
Representatives nor any past, present or future board member, partner, trustee, director, member,

act or omission of Tenant or any Agent, (iii) any breach of Tenant’s obligations under this Lease,
including failure to comply with Laws or surrender the Premises upon the expiration or earlier
termination of the Lease Term, or (iv) any entry by Tenant or any Agent upon the Land prior to the

or condition occurring on or after the date of such transfer. Within five (5) days after such
transferee’s request, Tenant shall attorn to such transferee and execute, acknowledge and deliver
any document submitted to Tenant confirming such Attornment provided such transferee recognizes
this Lease and assumes the obligations of Landlord hereunder which accrue from and after the date
of transfer.

     15.4. Tenant shall not have the right to set off or deduct any amount allegedly owed to Tenant
pursuant to any claim against Landlord from any rent or other sum payable t Landlord. Tenant’s
sole remedy for recovering upon such claim shall be to institute an independent action against
Landlord, which action shall not be consolidated with any action of Landlord.

26

 

     15.5. If Tenant or any Agent is awarded a money judgment against Landlord, then recourse for
satisfaction of such judgment shall be limited to execution against Landlord’s estate and interest
in the Building. No other asset of Landlord, and no asset of any of Landlord’s Representatives (or
any past, present or future board member, partner, director, member, officer, trustee, employee,
agent, representative or advisor of any of them (each, an “officer”)) or any other person or
entity, shall be available to satisfy or be subject to any such judgment. No such Landlord’s
Representative, officer or other person or entity shall be held to have personal liability for
satisfaction of any claim or judgment whatsoever under this Lease.

ARTICLE 16

RULES

     16.1. Tenant and Agents shall at all times abide by and observe the rules specified in Exhibit
C. Tenant and Agents shall also abide by and observe any other rule that Landlord may promulgate
from time to time for the operation and maintenance of the Building, provided that notice thereof
is given and such rule is not inconsistent with the provisions of this Lease. All rules shall be
binding upon Tenant and enforceable by Landlord as if they were contained herein. Nothing
contained in this Lease shall be construed as imposing upon Landlord any duty or obligation to
enforce such rules, or the terms, conditions or covenants contained in any other lease, as against
any other tenant, and Landlord shall not be liable to Tenant for the violation of such rules by any
other tenant or its employees, agents, assignees, subtenants, invitees or licensees. Landlord
shall use reasonable effort not to enforce any rule or regulation in a manner which unreasonably
discriminates among similarly situated tenants.

ARTICLE 17

DAMAGE OR DESTRUCTION

     17.1. If the Premises or the Building are totally or partially damaged or destroyed thereby
rendering the Premises totally or partially inaccessible or unusable, then Landlord shall
diligently repair and restore the Premises and the Building to substantially the same condition
they are in prior to such damage or destruction; provided, however, that if in Landlord’s judgment
such repair and restoration cannot be completed within one hundred eighty (180) days after the
occurrence of such damage or destruction (taking into account the time needed for effecting a
satisfactory settlement with any insurance company involved, removal of debris, preparation of
plans and issuance of al required governmental permits), then Landlord shall have the right to
terminate this Lease by giving written notice of termination within sixty (60) days after the
occurrence of such damage or destruction. If this Lease is terminated pursuant to this Article,
then rent shall be apportioned (based on the portion of the Premises which is usable or used after
such damage or destruction) and paid to the later of (a) the date of such casualty or destruction,
or (b) the date Tenant vacates the Premises. If this Lease is not terminated as a result of such
damage or destruction, then until such repair and restoration of the Premise are substantially
complete. Tenant shall be required to pay rent only for the portion of the Premises that is usable
while such repair and restoration are

27

 

being made; provided, however, that if such damage or destruction was caused by the act or
omission of Tenant or any Agent, then Tenant shall not be entitled to any such rent reduction.
After receipt of all insurance proceeds (including proceeds of insurance maintained by Tenant with
respect to Tenant Items), Landlord shall proceed with and bear the expenses of such repair and
restoration of the Premises and the Building; provided, however, that (a) if such damage or
destruction was caused by the act or omission of Tenant or any Agent, then Tenant shall pay
Landlord’s deductible and the amount by which such expenses exceed the insurance proceeds, if any,
actually received by Landlord on account of such damage or destruction, (b) Tenant shall pay the
amount by which the cost of restoring any item which Landlord is required to restore and Tenant is
required to insure exceeds the insurance proceeds received with respect thereto, and (c) Landlord
shall not be required to repair or restore any tenant improvements installed in the Premises
(except to the extent of any Building Standard Allowances provided by Landlord), any Alterations or
any other contents of the Premises (including, without limitation, Tenant’s trade fixtures,
decorations, furnishings, equipment or personal property). Notwithstanding anything herein to the
contrary, Landlord shall have the right to terminate this Lease if (1) insurance proceeds are
insufficient to pay the full cost of such repair and restoration, (2) the holder of any Mortgage
fails or refuses to make such insurance proceeds available for such repair and restoration, (3)
zoning or other applicable Laws or regulations do not permit such repair and restoration, or (4)
the damage to the Building exceeds twenty-five percent (25%) of the replacement value of the

condemned by any governmental or quasi-governmental authority for any public or quasi-public use or
purpose or sold under threat of such a taking or condemnation (collectively, “condemned”), then
this Lease shall terminate on the day prior to the date title thereto vests in such authority and
rent s hall be apportioned as of such date. If less than one-third of the Premises or occupancy
thereof is condemned, purposes, then this Lease shall continue in full force and effect as to the
part of the Premises not so condemned, except that as of the date title vests in such authority
Tenant shall not be required to pay rent with respect to the part of the Premises so condemned.
Notwithstanding anything herein to the contrary, if twenty-five percent (25%) or more of the Land
or the Building is condemned, then whether or not any portion of the Premises is condemned,
Landlord shall have the right to terminate this Lease as of the date title vests in such authority.

     18.2. All awards, damages and other compensation paid on account of such condemnation shall
belong to Landlord, and Tenant assigns to Landlord all rights to such awards, damages and
compensation. Tenant shall not make any claim against Landlord or such authority for any portion
of such award, damages or compensation attributable to damage to the Premises, value for the
unexpired portion of the Lease Term, loss of profits or goodwill, leasehold improvements or
severance damages.

28

 

Nothing contained herein, however, shall prevent Tenant from pursuing a separate claim against
the authority for relocation expenses and for the value of furnishings, equipment and trade
fixtures installed in the Premises at Tenant’s expense and which Tenant is entitled pursuant to
this Lease to remove at the expiration or earlier termination of the Lease Term, provided that such
claim shall I no way diminish the award, damages or compensation payable to or recoverable by
Landlord in connection with such condemnation.

ARTICLE 19

DEFAULT

     19.1. Each of the following shall constitute an “Event of Default:” (a) Tenant’s failure to
make when due any payment of the Base Rent, additional rent or other sum; provided, however, that
with respect to the first such failure in any twelve (12) month period only, no Event of Default
shall be deemed to have occurred unless such failure continues for a period of five (5) days after
Landlord delivers written notice thereof to Tenant (provided, further, however, that such notice
requirement and cure period shall no longer be applicable if Tenant fails to make any such payment
more than three (3) times during the Lease Term); (b) Tenant’s failure to perform or observe any
covenant or condition of this Lease not otherwise specifically described in this Section 19.1,
which failure shall continue for a period of ten (10) days after Landlord sends Tenant written
notice thereof (or such shorter period as is appropriate if such failure is capable of being cured
sooner); provided, however, that if such cure cannot reasonably be effected within such ten (10)
day period and Tenant begins such cure promptly within such ten (10) day period and is pursuing
such cure in good faith and with diligence and continuity during such ten (10) day period, then,
except in the event of an emergency, Tenant shall have such additional time up to an additional
thirty (30) days as is reasonably necessary to effect such cure; (c) Tenant’s failure to occupy
continuously the Premises; (d) an Event of Bankruptcy as specified in Article XX; (e) Tenant’s
dissolution or liquidation; (f) any Environmental Default as specified in Section 6.3; or (g) any

     19.2. If there shall be an Event of Default (even if prior to the Lease Commencement Date),
then the provisions of this Section shall apply. Landlord shall have the right, at its sole
option, to terminate this Lease. In addition, with or without terminating this Lease, Landlord may
re-enter, terminate Tenant’s right of possession and take possession of the Premises. The
provisions of this Article shall operate as a notice to quit, and Tenant hereby waives any other
notice to quit or notice of Landlord’s intention to re-enter the Premises or terminate this Lease.
If necessary, Landlord may proceed to recover possession of the Premises under applicable Laws, or
by such other proceedings, including re-entry and possession, as may be applicable. If Landlord
elects to terminate this Lease and/or elects to terminate Tenant’s right of possession, everything
contained in this Lease on the part of Landlord to be done and performed shall cease without
prejudice, however, to Tenant’s liability for all Base Rent, additional rent and other sums
specified herein. Whether or not this Lease and/or Tenant’s right of possession is terminated,
Landlord shall have the right, at its sole option, to terminate any renewal or

29

 

expansion right contained in this Lease and to grant or withhold any consent or approval
pursuant to this Lease in its sole and absolute discretion. Tenant hereby expressly waives, for
itself and all persons claiming by, through or under it, any right of redemption, re-entry or
restoration of the operation of this Lease under any present or future Law, including without
limitation any such right which Tenant would otherwise have in case Tenant shall be dispossessed
for any cause, or in case Landlord shall obtain possession of the Premises as herein provided.
Landlord may relet the Premises or any part thereof, alone or together with other premises, for
such term(s) (which may extend beyond the date on which the Lease Term would have expired but for
Tenant’s default) and on such terms and conditions (which may include any concessions or allowances
granted by Landlord) as Landlord, in its sole and absolute discretion, may determine, but Landlord
shall not be liable for, nor shall Tenant’s obligations hereunder be diminished by reason of, any
failure by Landlord to relet all or any portion of the Premises or to collect any rent due upon
such reletting. Whether or not this Lease is terminated or any such suit is instituted, Tenant
shall be liable for any Base Rent, additional rent, damages or other sum which may be due or
sustained prior to such default, and for all costs, fees and expenses (including, but not limited
to, attorneys’ fees and costs, brokerage fees, expenses incurred in placing the Premises in
first-class rentable condition, advertising expenses, and any concessions or allowances granted by
Landlord) incurred by Landlord in pursuit of its remedies hereunder and/or in recovering possession
of the Premises and renting the Premises to others from time to time. Tenant also shall be liable
for additional damages which at Landlord’s election s hall be either: (a) an amount equal to the
Base Rent and additional rent due or which would have become due from the date of Tenant’s default
through the remainder of the Lease Term, less the amount of rental, if any, which Landlord receives
during such period from others to whom the Premises may be rented (other than any additional rent
received by Landlord as a result of any failure of such other person to perform any of its
obligations to Landlord), which amount shall be computed and payable in monthly installments, in
advance, on the first day of each calendar month following Tenant’s default and continuing until
the date on which the Lease Term would have expired but for Tenant’s default, it being understood
that separate suits may be brought from time to time to collect any such damages for any month(s)
(and any such separate suit shall not in any manner prejudice the right of Landlord to collect any
damages for any subsequent month(s)), or Landlord may defer initiating any such suit until after
the expiration of the Lease Term (in which event such deferral shall not be construed as a waiver
of Landlord’s rights as set forth herein and Landlord’s cause of action shall be deemed not to have
accrued until the expiration of the Lease Term); or (b) an amount equal to the difference between
(i) all Base Rent, additional rent and other sums due or which would be due and payable under this
Lease as of the date of Tenant’s default through the end of the scheduled Lease Term, and (ii) the
fair market value rental of the Premises over the same period (net of all expenses (including
attorneys’ fees) and all vacancy periods reasonably projected by Landlord to be incurred in
connection with the reletting of the Premises), as determined by Landlord in nits sole and absolute
discretion, which difference s hall be discounted at a rate equal to one (1) whole percentage point
above the prime rate published in the Money Rates section of the Wall Street Journal, and which
resulting amount shall be payable to Landlord in a lump sum on demand, it being understood that
upon payment of such liquidated and agreed final

30

 

damages, Tenant shall be released from further liability under this Lease with respect to the
period after the date of such payment, and that Landlord may bring suit to collect any such damages
at any time after an Event of Default shall have occurred. Tenant s hall pay all expenses
(including attorneys’ fees) incurred by Landlord in connection with or as a result of any Event of
Default whether or not a suit is instituted. The provisions contained in this Section shall be in
addition to, and shall not prevent the enforcement of, any claim Landlord may have against Tenant
for anticipatory breach of this Lease (including, without limitation, the right of injunction and
the right to invoke any remedy allowed at law or in equity as if reentry, summary proceedings and
other remedies were not provided for herein). Nothing herein shall be construed to affect or
prejudice Landlord’s right to prove, and claim in full, unpaid rent accrued prior to termination of
this Lease. If Landlord is entitled, or Tenant is required, pursuant to any provision hereof to
take any action upon the termination of the Lease Term, then Landlord s hall be entitled, and
Tenant shall be required, to take such action also upon the termination of Tenant’s right of
possession. Notwithstanding anything contained in this Lease to the contrary, the amount of any
damages or awards collectible by Landlord with respect to Base Rent and additional rent due under
this Lease shall be limited to one-year’s worth of Base Rent and additional rent due under the
Lease from and after the Event of Default plus the unpaid Base Rent and additional rent due under
the Lease through the date of the Event of Default.

     19.3. All rights and remedies of Landlord set forth in this Lease are cumulative and in
addition to all other rights and remedies available to Landlord at law or in equity, including
those available as a result of any anticipatory breach of this Lease. The exercise by Landlord of
any such right or remedy shall not prevent the concurrent or subsequent exercise of any other
rights or remedy. No delay or failure by Landlord to exercise or enforce any of Landlord’s rights
or remedies or Tenant’s obligations shall constitute a waiver of any such or subsequent rights,
remedies of obligations. Landlord shall not be deemed to have waived any default by Tenant unless
such waiver expressly is set forth in a written instrument signed by Landlord. If Landlord waives
in writing any default by Tenant, such waiver shall not be construed as a waiver of any covenant,
condition or agreement set forth in this Lease except as to the specific circumstances described in
such written waiver.

     19.4. If Landlord shall institute proceedings against Tenant and a compromise or settlement
thereof shall be made, then the same shall not constitute a waive of the same or of any other
covenant, condition or agreement set forth herein, nor of any of Landlord’s rights hereunder.
Neither the payment by Tenant of a lesser amount than the monthly installment of Base Rent,
additional rent or of any sums due hereunder nor any endorsement or statement on any check or
letter accompanying a check for payment of rent or other sums payable hereunder shall be deemed an
accord and satisfaction. Landlord may accept the same without prejudice to Landlord’s right to
recover the balance of such rent or other sums or to pursue any other remedy. Notwithstanding any
request or designation by Tenant, Landlord may apply any payment received from Tenant to any
payment then due. No re-entry by Landlord, and no

31

 

acceptance by Landlord of keys from Tenant, shall be considered an acceptance of a surrender
of this Lease.

     19.5. If Tenant fails to make any payment to any third part or to do any act herein required
to be made or done by Tenant, then Landlord may, but shall not be required to, make such payment or
do such act. The taking of such action by Landlord shall not be considered a cure of such default
by Tenant or prevent Landlord from pursuing any remedy it is otherwise entitled to in connection
with such default. If Landlord elects to make such payment or do such act, then all expenses
incurred by Landlord, plus interest thereon at a rate (the “Default Rate”) equal to the greater of
eighteen percent (18%) per annum or the rate per annum which is five (5) whole percentage points
higher than the prime rate published in the Money Rates section of the Wall Street Journal, from
the date incurred by Landlord to the date of payment thereof by Tenant, shall constitute additional
rent due hereunder; provided, however, that nothing contained herein shall be construed as
permitting Landlord to charge or receive interest in excess of the maximum rate then allowed by
law.

     19.6. If Tenant fails to make any payment of Base Rent, additional rent or any other sum on or
before the fifth (5th) day after the date such payment is due and payable (without regard to any
grace period that may be specified in Section 19.1) under this Lease, then Tenant shall pay to
Landlord a late charge of five percent (5%) of the amount of such payment. In addition, such
payment and such late fee shall bear interest at the Default Rate from the date such payment or
late fee, respectively, became due to the date of payment thereof by Tenant; provided, however,
that nothing contained herein shall be construed as permitting Landlord to charge or receive
interest in excess of the maximum rate then allowed by law. Notwithstanding any of the foregoing
to the contrary, Landlord shall waive such late fee (but not the interest payable pursuant to the
preceding sentence) the first (1st) time in each calendar year that Tenant fails to make a payment
when due, provided such payment is made before the expiration of the grace period specified in
Section 19.1(a). Such late charge and interest shall constitute additional rent due hereunder
without any notice or demand.

     19.7. [Reserved]

     19.8. If more than one natural person or entity shall constitute Tenant, then the liability of
each such person or entity shall be joint and several. If Tenant is a general partnership or other
entity the partners or members of which are subject to personal liability, then the liability of
each such partner or member shall be joint and several. No waiver, release or modification of the
obligations of any such person or entity shall affect the obligations of any other such person or
entity.

ARTICLE 20

BANKRUPTCY

     20.1. An “Event of Bankruptcy” is the occurrence with respect to any of Tenant, a Guarantor or
any other person liable for Tenant’s obligations hereunder

32

 

(including, without limitation, any general partner of Tenant (a “General Partner”)) or any of
the following: (a) such person becoming insolvent, as that term is defined in Title 11 of the
United States Code (the “Bankruptcy Code”) or under the insolvency laws of any state (the
“Insolvency Laws”) other than in connection with the bankruptcy proceeding pending as of the date
of this Lease (i.e., Case #05-12801 filed in the United States Bankruptcy Court, Eastern District
of Virginia on September 8, 2005) the “Pending Bankruptcy”); (b) appointment of a receiver or
custodian for any property of such person, or the institution of a foreclosure or attachment action
upon any property of such person other than in connection with the Pending Bankruptcy; (c) filing
by such person of a voluntary petition under the provisions of the Bankruptcy Code or Insolvency
Laws other than in connection with the pending Bankruptcy; (d) filing of an involuntary petition
against such person as the subject debtor under the Bankruptcy Code or Insolvency Laws other than
in connection with the Pending Bankruptcy, which either (1) is not dismissed within thirty (30)
days after filing, or (2) results in the issuance of an order for relief against the debtor; (e)
such person making or consenting to an assignment for the benefit of creditors or a composition of
creditors other than in connection with the Pending Bankruptcy; (f) such person submitting (either
before or after execution hereof) to Landlord any financial statement containing any material
inaccuracy or omission; (g) or any admission by Tenant or Guarantor of its inability to pay debts
as they become due other than in connection with the Pending Bankruptcy. At any time upon not less
than five (5) days’ prior written notice, Tenant shall submit such information concerning the
financial condition of Tenant, a Guarantor or any other person liable for Tenant’s obligations as
Landlord may request. Tenant warrants that all such information heretofore and hereafter submitted
is and shall be correct and complete.

     20.2. Upon occurrence of an Event of Bankruptcy, Landlord shall have all rights and remedies
available pursuant to Article XIX; provided, however, that while a case (the “Case”) in which
Tenant is the subject debtor under the Bankruptcy Code is pending, Landlord’s right to terminate
this Lease shall be subject, to the extent required by the Bankruptcy Code, to any rights of Tenant
or its trustee in bankruptcy (collectively, “Trustee”) to assume or assume and assign this Lease
pursuant to the Bankruptcy Code. After the commencement of a Case: (i) Trustee shall perform all
post-petition obligations of Tenant under this Lease; and (ii) if Landlord is entitled to damages
(including, without limitation, unpaid rent) pursuant to the terms of this Leases, then all such
damages shall be entitled to administrative expense priority pursuant to the Bankruptcy Code. Any
person or entity to which this Lease is assigned pursuant to the Bankruptcy Code shall be deemed
without further act or deed to have assumed all of the obligations arising under this Lease on and
after the date of assignment, and any such assignee shall upon request execute and deliver to
Landlord an instrument confirming such assumption. Trustee shall not have the right to assume or
assume and assign this Lease unless Trustee promptly (a) cures all defaults under this Lease, (b)
compensates Landlord for damages incurred as a result of such defaults, (c) provides adequate
assurance of future performance on the part of Trustee as debtor in possession or Trustee’s
assignee, and (d) complies with all other requirements of the Bankruptcy Code. If Trustee desires
to assume and assign this Lease to any person who shall have made a bona fide offer, then Trustee
shall give Landlord written notice of such proposed assignment (which notice shall set forth the
name and

33

 

address of such person, all of the terms and conditions of such offer, and the adequate
assurance to be provided Landlord to assure such person’s future performance under this Lease) no
later than fifteen (15) days after receipt by Trustee of such offer, but in no event later than
thirty (30) days prior to the date Trustee shall make application to the appropriate court for
authority and approval to enter into such assignment and assumption, and Landlord shall thereupon
have the prior right and option, to be exercised by notice to Trustee given at any time prior to
the effective date of such proposed assignment, to accept (or to cause Landlord’s designee to
accept) an assignment of this Lease upon the same terms and conditions and for the same
consideration, if any, as the bona fide offer made by such person, less any brokerage commissions
which may be payable out of the consideration to be paid by such person for he assignment of this
Lease. If Trustee fails assume or assume and assign this Lease in accordance with the requirements
of the Bankruptcy Code within sixty (60) days after the initiation of the Case, then Trustee shall
be deemed to have rejected this Lease. If this Lease is rejected or deemed rejected, then Landlord
shall have all rights and remedies available to it pursuant to Article XIX. Adequate protection of
Landlord’s right, title and interest in and to the Premises, and adequate assurance of future
performance, shall require, among other things, that the following minimum criteria be met: (1)
Tenant’s gross receipts in the ordinary course of business during the thirty (30) days preceding
the Case must be greater than ten (10) times the next monthly installment of Base Rent and
additional rent due; (2) Both the average and median of Tenant’s monthly gross receipts in the
ordinary course of business during the seven (7) months preceding the Case must be greater than the
next monthly installment of Base Rent and additional rent due; (3) Trustee must pay its estimated
pro-rata share of the cost of all services performed or provided by Landlord (whether directly or
through agents or contractors and whether or not previously included as part of Base Rent) in
advance of the performance or provision of such services; (4) Trustee must agree that Tenant’s
business shall be conducted in a first-class manner, and that no liquidating sale, auction or other
non-first-class business operation shall be conducted in the Premises; (5) Trustee must agree that
the use of the Premises as stated in this Lease shall remain unchanged and that no prohibited use
shall be permitted; (6) Trustee must agree that the assumption or assumption and assignment of this
Lease shall not violate or affect the rights of other tenants of the building; (7) Trustee must pay
at the time the next monthly installment of Base Rent is due, in addition to such installment, an
amount equal to the monthly installments of Base Rent, and additional rent due for the next six (6)
months thereafter, such amount to be held as a security deposit; (8) Trustee must agree to pay, at
any time Landlord draws on such security deposit, the amount necessary to restore such security
deposit to its original amount; (9) Trustee must comply with all duties and obligations of Tenant
under this Lease; and (10) All assurances of future performance specified in the Bankruptcy Code
must be provided.

ARTICLE 21

SUBORDINATION

     21.1. This Lease is subject and subordinate to the lien, provisions, operation and effect of
all mortgages, deeds of trust, ground leases or other security instruments which may now or
hereafter encumber the Building or the Land (collectively,

34

 

“Mortgage”), to all funds and indebtedness intended to be secured thereby, and to all
renewals, extensions, modifications, recastings or refinancings thereof. Said subordination and
the provisions of this Section shall be self-operative and no further instrument of subordination
shall be required by the holder of any Mortgage. The holder of any Mortgage to which this Lease is
subordinate shall have the right (subject to any required approval of the holders of any superior
Mortgage) at any time to declare this Lease to be superior to the lien, provisions, operation and
effect of such Mortgage and Tenant shall execute, acknowledge and deliver all documents required by
such holder in confirmation thereof.

     21.2. Tenant shall at Landlord’s request promptly execute any requisite or appropriate
document confirming such subordination. Tenant appoints Landlord as Tenant’s attorney-in-fact to
execute any such document for Tenant. Tenant waives the provisions of any statute or rule of law
now or hereafter in effect which may give or purport to give Tenant any right to terminate or
otherwise adversely affect this Lease and Tenant’s obligations hereunder in the event any
foreclosure proceeding is prosecuted or completed or in the event the Building, the Land or
Landlord’s interest therein is transferred by foreclosure, by deed in lieu of foreclosure of
otherwise. If this Lease is not extinguished upon any such transfer or by the transferee following
such transfer, at the request of such transferee, Tenant shall attorn to such transferee and shall
recognize such transferee as the landlord under this Lease. Tenant agrees that upon any such
attornment, such transferee shall not be (a) bound by any payment of the Base Rent or additional
rent more than one (1) month in advance, except prepayments in the nature of security for the
performance by Tenant of its obligations under this Lease, but only to the extent such prepayments
have been delivered to such transferee, (b) bound by any amendment of this Lease made without the
consent of the holder of each Mortgage existing as of the date of such amendment, (c) liable for
damages for any breach, act or omission of any prior landlord, or (d) subject to any offsets or
defenses which Tenant might have against any prior landlord; provided, however, that after
succeeding to Landlord’s interest under this Lease, such transferee shall agree to perform in
accordance with the terms of this Lease all obligations of Landlord arising after the date of
transfer. Within five (5) days after the request of such transferee, Tenant s hall execute,
acknowledge and deliver any requisite or appropriate document submitted to tenant confirming such
attornment.

     21.3. If any prospective or current holder of a Mortgage requires that modifications to this
Lease be obtained, and provided that such modifications (a) are reasonable, (b) do not adversely
affect in a material manner Tenant’s use of the Premises as herein permitted, and (c) do not
increase the rent and other sums to be paid by Tenant, then Landlord may submit to Tenant an
amendment to this Lease incorporating such required modifications, and Tenant shall execute,
acknowledge and deliver such amendment to Landlord within five (5) days after Tenant’s receipt
thereof.

ARTICLE 22

HOLDING OVER

35

 

     22.1. Tenant acknowledges that it is extremely important that Landlord have substantial
advance notice of the date on which Tenant will vacate the Premises, because Landlord will require
an extensive period to locate a replacement tenant and because Landlord plans its entire leasing
and renovation program for the Building in reliance on its lease expiration dates. Tenant also
acknowledges that if Tenant fails to surrender the Premises or any portion thereof at the
expiration or earlier termination of the Lease Term, then it will be conclusively presumed that the
value to Tenant of remaining in possession, and the loss that will be suffered by Landlord as a
result thereof, far exceed the Base Rent and additional rent that would have been payable had the
Lease Term continued during such holdover period. Therefore, if Tenant (or anyone claiming through
Tenant) does not immediately surrender the Premises or any portion thereof upon the expiration or
earlier termination of the Lease Term, then the rent payable by Tenant hereunder shall be increased
to equal the greater of (1) fair market rent for the entire Premises, or (2) double the Base Rent,
additional rent and other sums that would have been payable pursuant to the provisions of this
Lease if the Lease Term had continued during such holdover period. Such rent shall be computed by
Landlord and paid by Tenant on a monthly basis and shall be payable on the first day of such
holdover period and the first day of each calendar month thereafter during such holdover period
until the Premises have been vacated. Notwithstanding any other provision of this Lease,
Landlord’s acceptance of such rent shall not in any manner adversely affect Landlord’s other rights
and remedies, including Landlord’s right to evict Tenant and to recover all damages. Any such
holdover shall be deemed to be a tenancy-at-sufferance and not a tenancy-at-will or tenancy from
month-to-month. In no event shall any holdover be deemed a permitted extension or renewal of the
Lease Term, and nothing contained herein shall be construed to constitute Landlord’s consent to any
holdover or to give Tenant any right with respect thereto.

ARTICLE 23

COVENANTS OF LANDLORD

     23.1. Landlord covenants that it has the right to enter into this Lease, and that if Tenant
shall perform timely all of its obligations hereunder, then, subject to the provisions of this
Lease, Tenant shall during the Lease Term peaceably and quietly occupy and enjoy the full
possession of the Premises without hindrance by Landlord, or anyone claiming by, through or under
Landlord.

     23.2. Landlord reserves the following rights: (a) to change the street address and name of
the Building; (b) to change the arrangement and location of entrances, passageways, doors,

Building not in consistent with Tenant’s permitted use of the Premises; (e) to exclusively use
and/or lease the roof areas, the sidewalks and other exterior areas; (f) to subdivide the Land or
to combine the Land with other lands; (g) to relocate any parking areas designated for Tenant’s
use; (h) if Tenant vacates the Premises prior to the expiration of the Lease Term, to make

36

 

Alterations to or otherwise prepare the Premises for reoccupancy without relieving Tenant of
its obligation to pay all Base Rent, additional rent and other sums due under this Lease through
such expiration; (i) to construct improvements (including kiosks) on the Land and in the public and
common areas of the Building; (j) to prohibit smoking in the entire Building or portions thereof
(including the Premises), so long as such prohibitions are in accordance with applicable law; and
(k) if any excavation or other substructure work shall be made or authorized to be made upon land
adjacent to the Building or the Land, to enter the Premises for the purpose of doing such work is
as required to preserve the walls of the Building and to preserve the land from injury or damage
and to support such walls and land by proper foundations. Landlord may exercise any or all of the
foregoing rights without being deemed to be guilty of an eviction, actual or constructive, or a
disturbance of Tenant’s business or use or occupancy of the Premises and Tenant shall have no claim
against Landlord in connection therewith.

ARTICLE 24

PARKING

     24.1. Tenant shall have the right to utilize the Building’s parking facilities (which
facilities are provided at the rate of four (4) parking spaces per one thousand (1,000) square feet
of rentable area), at no charge, on a non-exclusive and unreserved basis with other tenants of the
Building for the parking of standard-sized passenger automobiles and upon such terms and conditions
as may from time to time be established by Landlord. Landlord reserves the right in its absolute
discretion to determine whether the parking facilities are becoming crowded and to allocate and
assign parking spaces among Tenant and the other tenants. If Landlord, in its sole and absolute
discretion, grants to any other tenants of the Building the exclusive right to use any particular
parking spaces, then neither Tenant nor its employees or visitors shall use such spaces. Tenant
shall not use parking areas for the servicing or overnight storage of vehicles. Tenant shall not
assign, sublet or transfer any rights with respect to the parking facilities. Landlord reserves
the right to institute either a valet parking system or a self-parking system. It is understood
and agreed that Landlord assumes no responsibility, and shall not be held liable, for any damage or
loss to any automobiles parked in the parking facilities or to any personal property located
therein, or for any injury sustained by any person in or about the parking facilities. Landlord
reserves the right to close the parking facilities during periods of unusually inclement weather or
for repairs. Landlord shall not be liable to Tenant and this Lease shall not be affected if any
parking rights hereunder are impaired by any Law imposed after the Lease Commencement Date.

ARTICLE 25

GENERAL PROVISIONS

     25.1. Tenant acknowledges that neither Landlord nor any broker, agent or employee of Landlord

herein expressly set forth, and no right, privilege, easement or license is being acquired by
Tenant except as herein expressly set forth.

37

 

     25.2. Nothing contained in this Lease shall be construed as creating any relationship between
Landlord and Tenant other than that of landlord and tenant. Tenant shall not use the name of the
Building for any purpose other than as the address of the business to be conducted by Tenant in the
Premises, use the name of the Building as Tenant’s business address after Tenant vacates the
Premises, or do or permit to be done anything in connection with Tenant’s business or advertising

Building and Tenant.

     24.3. Landlord and Tenant each warrants to the other that in connection with this Lease it has
not employed or dealt with any broker, agent or finder, other than the Brokers. Landlord

for brokerage or other commission asserted by any broker, agent or finder employed by Tenant or
with whom Tenant has dealt, other than the Brokers. Landlord shall indemnify and hold Tenant

agent or finder employed by Landlord or with whom Landlord has dealt other than the Brokers.

notice, Tenant and each subtenant, assignee, licensee or concessionaire or occupant of Tenant shall
execute, acknowledge and deliver to Landlord and/or any other person or entity designated by
Landlord, a written statement certifying: (a) 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

Landlord may reasonably request. Any such statement may be relied upon by any other of the
Building or the Land, any prospective purchaser of the Building or the Land, any holder or
prospective holder of a Mortgage or any other person or entity. Tenant acknowledges that time is
of the essence to the delivery of such statements and that Tenant’s failure to deliver timely such
statements may cause substantial damages resulting from, for example, delays in obtaining financing
secured by the Building. Tenant shall be liable for all such damages. If any such statement is
not delivered timely by Tenant, then all matters contained in such statement shall be deemed true
and accurate.

     25.5. LANDLORD, TENANT, ALL GUARANTORS AND ALL GENERAL PARTNERS EACH WAIVES TRIAL BY JURY IN
ANY ACTION, PROCEEDING, CLAIM OR COUNTERCLAIM BROUGHT IN CONNECTION WITH ANY MATTER ARISING OUT OF
OR IN ANY WAY CONNECTED WITH THIS

PREMISES, AND/OR ANY CLAIM OF INJURY OR DAMAGE, TENANT CONSENTS TO SERVICE OF PROCESS AND ANY
PLEADING RELATING TO ANY SUCH ACTION AT THE PREMISES; PROVIDED, HOWEVER, THAT NOTHING HEREIN SHALL
BE CONSTRUED AS REQUIRING SUCH SERVICE AT THE PREMISES. LANDLORD, TENANT, ALL GUARANTORS AND ALL
GENERAL PARTNERS EACH WAIVES ANY OBJECTION TO THE VENUE OF ANY ACTION FILED IN ANY COURT SITUATED
IN THE JURISDICTION IN WHICH THE BUILDING IS LOCATED, AND WAIVES ANY RIGHT, CLAIM OR POWER, UNDER
THE DOCTRINE OF FORUM NON CONVENIENS OR OTHERWISE, TO TRANSFER ANY SUCH ACTION TO ANY OTHER COURT.

     25.6. All notices or other communications required under this Lease shall be in writing and
shall be deemed duly given and received when delivered in person (with receipt therefore), on the

specified in Article I. Either party may change its address for the giving of notices by notice
given in accordance with this Section. If Landlord or the holder of any Mortgage notifies Tenant
that a copy of any notice to Landlord shall be sent to such holder at a specified address, then
Tenant shall send (in the manner specified in this Section and at the same time such notice is sent
to Landlord) a copy of such notice to such holder, and no such notice shall be considered duly sent
unless such copy is no sent to such holder. Any such holder shall have thirty (30) days after
receipt of such notice to cure any Landlord default before Tenant may exercise any remedy. Any
cure of Landlord’s default by such holder shall be treated as performance by Landlord.

     25.7. Each provision of this Lease shall be valid and enforceable to the fullest extent
permitted by law. If any provision of this Lease or the application thereof to any person or
circumstances shall to any extent be invalid or unenforceable, then such provision shall be deemed
to be replaced by the valid an enforceable provision most substantively similar to such invalid or
unenforceable provision, and the remainder of this Lease and the application of such provision to
persons or circumstances other than those as to which it is invalid or unenforceable shall not be
affected thereby. Nothing contained in this Lease shall be construed as permitting Landlord to
charge or receive interest in excess of the maximum rate allowed by law.

     25.8. Feminine, masculine or neuter pronouns shall be substituted for those of another form,
and the plural or singular shall be substituted for the other number, in any place in which the
context may require such substitution.

39

 

     25.9. The provisions of this Lease shall be binding upon and inure to the benefit of the
parties and each of their respective representatives, successors and assigns, subject to the
provisions herein restricting assignment or subletting.

     25.10. This Lease contains and embodies the entire agreement of the parties hereto and
supersedes all prior agreements, negotiations, letters, of intent, proposals, representations,
warranties, understandings, suggestions and discussions, whether written or oral, between the
parties hereto. Any representation, inducements, warranty, understanding or agreement that is not
expressly set forth in this Lease shall be of no force or effect. This Lease may be modified or
changed in any manner only by an instrument signed by both parties. This Lease includes and
incorporates all exhibits attached hereto. Tenant shall at Landlord’s request promptly execute any
requisite document, certificate or instrument that is reasonably necessary or desirable to clarify
or carry out the force and effect of any term or condition of, or obligation of Tenant under, this
Lease.

presumption that this Lease be construed more strictly against the party who itself or through its
agent prepared it (it being agreed that all parties hereto have participated in the preparation of
this Lease and that each party had the opportunity to consult legal counsel before the execution of
this Lease). No custom or practice which may evolve between the parties in the administration of
the terms of this Lease shall be construed to waive Landlord’s right to insist on Tenant’s strict
performance of the terms of this Lease.

     25.12. Headings are used for convenience and shall not be considered when construing this
Lease.

     25.13. The submission of an unsigned copy of this document to Tenant shall not constitute an
offer or option to lease the Premises. This Lease shall become effective and binding only upon
execution and delivery by both Landlord and Tenant.

     25.14. Time is of the essence with respect to each of Tenant’s obligations hereunder.

     25.15. This Lease may be executed in multiple counterparts, each of which shall be deemed an
original and all of which together constitute one and the same document. Faxed signatures shall
have the same binding effect as original signatures.

     25.16. Neither this Lease nor a memorandum thereof shall be recorded.

     25.17. Landlord reserves the right to make reasonable changes and modifications to the plans

Tenant no later than ten (10) days after the date Landlord notifies Tenant of the amount thereof.

     25.20. Tenant’s liabilities and obligations with respect to the period prior to the expiration
or earlier termination of the Lease Term shall survive such expiration or earlier termination.

     25.21. If Landlord is in any way delayed or prevented from performing any of its obligations
due to fire, act of God, governmental act or failure to act, strike, labor dispute, inability to
procure materials, or any cause beyond Landlord’s reasonable control (whether similar or dissimilar
to the foregoing events), then the time for performance of such obligation shall be excused for the
period of such delay or prevention and extended for a period equal to the period of such delay,
interruption or prevention.

     25.22. Landlord’s review, approval and consent powers (including the right to review plans and
specifications) are for its benefit only. Such review, approval or consent (or conditions imposed
in connection therewith) shall be deemed not to constitute a representation concerning legality,
safety or any other matter.

     25.23. The deletion of any printed, typed or other portion of this Lease shall not evidence
the parties’ intention to contradict such deleted portion. Such deleted portion shall be deemed
not to have been inserted in this Lease.

     25.24. At the expiration or earlier termination of the Lease Term, Tenant shall deliver to
Landlord all keys and security cards to the Building and the Premises, whether such keys were
furnished by Landlord or otherwise procured by Tenant, and shall inform Landlord of the combination
of each lock, safe and vault, if any, in the Premises.

represent and warrants that such person is duly authorized to so act; that Tenant is duly
organized, is qualified to do business in the jurisdiction in which the Building is located, is in
good standing under the Laws of the state of its organization and the Laws of the jurisdiction in
which the Building is located, and has the power and authority to enter into this Lease; that is
not, and the entities or individuals constituting Tenant or which may own or control Tenant or
which may be owned or controlled by Tenant are not, among the individuals or entities identified on
any list compiled by the U.S. Government for the purpose of identifying suspected terrorists, and
Tenant is not

41

 

engaging in the transaction on behalf of any such individual or entity; that Tenant is not in
violation of any anti-money laundering Law; and that all action required to authorize Tenant and
such person to enter into this Lease has been duly taken.

     25.26. Any elimination or shutting off of light, air, or view by any structure which may be
erected on lands adjacent to the Building shall in no way effect this Lease or impose any liability
