|2.3 Tenants Option to
Extend Term. Provided Tenant is not in default of its obligations to the
Landlord pursuant to this Lease and any applicable cure period has not expired,
Tenant, at Tenants discretion, shall have the option to extend the Term of
this Lease for all or any portion of the Premises (provided that in no event
shall the area of the Premises to be renewed be less than either (i) the Second
Floor Key Area (as defined in Section 9) or (ii) one (1) full floor in the
Building if the area to be renewed is not the Second Floor Key Area) for one
(1) additional period of either five (5) years or three (3) years (the Renewal
Term), to commence immediately upon the expiration of the Initial Term
upon the same terms, covenants and conditions contained in this Lease, except
that (i) Tenant shall pay to Landlord as base rent during the Renewal Term the
then Prevailing Market Rate for the Premises as hereinafter
defined, and (ii) the Base Taxes and Base Building Expenses shall be adjusted
to the most recently completed Tax Year and calendar year, respectively.


For purposes of this Section 2.3,
the term Prevailing Market Rental shall mean the annual per
rentable square foot rental rate then being charged in new leases consummated
within six (6) months prior to the date of Tenants Notice, which such leases
are for Class A office premises comparable to the Premises and located in
office buildings comparable to the Building within a ten (10) mile radius of
the Building (excluding the Town Center, Columbia). In the determination of the
Prevailing Market Rental, the following factors shall be used in
making any such determination (i) consideration of annual rental rates per
rentable square foot; (ii) total rentable square feet leased; (iii) types of
escalation clauses (including without limitation operation expense stops, real
estate tax stops, and Consumer Price Index adjustments); (iv) length of
relevant term; (viii) utilities or services included within the base rent for
the comparable premises (including by way of example and not by way of
limitation electricity); (v) the brokerage commissions with respect to such
comparable premises, and (vi) the tenant improvement allowances with respect to
such comparable premises, if any. Notwithstanding the foregoing, the comparable
leases shall (i) have at least a five (5) year term, (ii) contain at least
10,000 square feet of space, and (iii) be in a building which is not newer than
the Building. All rent payable with respect to the Renewal Term shall be
payable in the same manner set forth in Section 5.1 of this Lease.


In order to exercise its option
granted herein, Tenant shall so notify Landlord in writing of its intent to
renew and the length of the Renewal Term not less than two hundred seventy
(270) days prior to the expiration of the Initial Term. Tenants renewal notice
shall also include the exact area of the Premises to be renewed (provided that
in no event shall the area of the Premises to be renewed be less than either
(i) the Second Floor Key Area, or (ii) one (1) full floor in the Building if
the area to be renewed is not the Second Floor Key Area). Within thirty (30)
days following the exercise by Tenant of its option to extend the Lease for the
Renewal Term, Landlord shall notify Tenant in writing of its determination of
the Prevailing Market Rate for the Renewal Term as reasonably determined by
Landlord. Within twenty (20) days of Tenants receipt of Landlords
notification of such rate determined by Landlord, Tenant shall notify Landlord
in writing of Tenants acceptance or rejection of such rate. If by Tenants
written notice to Landlord given within the aforesaid twenty (20) day period,
Tenant shall accept such Prevailing Market Rate, the Landlord and Tenant shall
enter into an amendment to this Lease acknowledging such renewal and setting
forth any terms at variance with the terms of this Lease. If by Tenants
written notice to Landlord given within the aforesaid twenty (20) day period,
Tenant shall reject such Prevailing Market Rate as determined by Landlord for
the Renewal Term, then within twenty (20) days thereafter, Landlord and Tenant
shall each appoint an independent commercial leasing broker licensed in the
Maryland area (the Brokers). Such brokers shall deliver their respective
estimates of the Prevailing Market Rate within ten (10) days after being
appointed. If the estimates of the Prevailing Market Rate as quoted by the
Brokers are within ten percent (10%) of each other, the Prevailing Market Rate
shall be deemed to be the average of the estimates presented by the Brokers. If
the estimates of the Prevailing Market Rate as quoted by the Brokers differ by
more than ten percent (10%), then the Brokers shall appoint a third independent
commercial leasing broker licensed in the Maryland area within ten (10) days
after the delivery of their estimates (the Third Broker) who shall deliver
its estimate of the Prevailing Market Rate within ten (10) days after being
appointed and such estimate shall be deemed to be the Prevailing Market Rate.
Tenant shall notify Landlord within ten (10) days after receipt of the estimate
of the Prevailing Market Rate (whether as resulting from the average of the
Brokers or from the Third Broker, as applicable), whether Tenant shall accept
such Prevailing Market Rate, whereupon Landlord and Tenant shall enter into an
amendment to this Lease acknowledging such renewal and setting forth any terms
at variance with the terms of this Lease. If Tenant does not accept such
Prevailing Market Rate within the aforesaid ten (10) day period, then Tenants
option to extend the Lease for the Renewal Term shall be void and inoperable.
Landlord and Tenant shall each pay the fee of the broker designated by them
originally and shall split the fees of the Third Broker.
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|Further, the option to extend the
Term shall be void and inoperable if Tenant (or its permitted assignee or
sublessee) is not in occupancy and possession of the Premises under this Lease
at the time of giving such notice, if Tenant shall be in default under any of
the terms of this Lease beyond the expiration of any applicable cure period at
the time of exercising its option to renew, if Tenant does not deliver the
requisite notice exercising its option to renew within the time period
specified above, and/or if Tenant shall fail to respond to Landlords
initial notice of the Prevailing Market Rate within the time period specified
above. The option granted herein shall not be severed from this Lease, or
separately sold, assigned or transferred; provided, however, such option may be
assigned or transferred together with the Lease subject to the terms of Section
19 hereof.


2.4 Definition of Term As used
herein, the word Term shall refer to the Initial Term and the Renewal Term,
if any.


3. Intentionally Left Blank.


4. Use. Tenant and/or its assignees and sublessees shall use and
occupy the Premises continuously during the Term of this Lease solely for
general office purposes and a computer systems data center in accordance with
applicable zoning regulations and for no other purpose.

setoff or demand in accordance with the following schedule:

amount, at the time of payment of monthly installments of Base Rent. In such
event, Tenant shall pay, or Landlord shall refund or credit to Tenants

receipt by Tenant of the written statement of the Taxes due if no audit is
performed by Tenant, the same shall be conclusive and binding on Tenant. No
credit shall be given to Tenant if the cost of Taxes Per Square Foot are less
than the Base Year Taxes.

shall hereafter change the tax year to a calendar year, or to a fiscal year
commencing on a date other than July 1, appropriate adjustments shall be made
in the computation of any additional rent due hereunder.


All reasonable expenses incurred
by Landlord (including attorneys, appraisers and consultants fees,

In each year of the Term, Landlord shall pay all Building Expenses, subject to
payment by Tenant of additional rent, if any, calculated in accordance with
Section 5.4.2 below. After the end of each calendar year, Landlord shall
compute the Building Expenses for such year and shall allocate such costs to

area for any year which is wholly or partly within the Term are greater than
the Base Year Building Expenses, Tenant shall pay to Landlord, as additional
rent, the amount of such excess times the number of rentable square feet in the
Premises, as set forth in Section 1 above. Within ninety (90) days after
receipt by Tenant of the written statement of the Building Expenses due, Tenant
shall have the right to audit Landlords records with respect to any such
increases in rent; provided, however, that unless Tenant shall have given
Landlord written notice of exception to any such statement upon the later of
(i) the date which is within thirty (30) days after audit thereof if an audit
is performed, or (ii) the date which is ninety (90) days after the receipt by
Tenant of the written statement of the Building Expenses due if no audit is
performed by Tenant, the same shall be conclusive and binding on Tenant. The
written statement of Building Expenses shall state the components of Building
Expenses incurred for the subject year. No credit shall be given to the Tenant
if the cost of Building Expenses Per Square Foot are less than the Base Year
Building Expenses. Notwithstanding anything to the contrary contained herein
Landlord shall use diligent efforts to keep Building Expenses at reasonable
amounts, while maintaining the Building as a first class office building.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|
|

| | 5.4.3.
Notwithstanding anything in this Section 5.4 to the contrary, in no event shall
Tenants share of increase in Building Expenses for those items within
Landlords discretion and control (which specifically excludes Building
Expenses relating to utilities, snow removal, insurance premiums, and Taxes),
exceed in any given year five percent (5%) from the amount paid by Tenant for
Building Expenses for the immediately prior year.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5.5 Additional Rent Payments.
Tenants obligation to pay any additional rent accruing during the Term
pursuant to Sections 5.3 and 5.4 hereof shall apply pro rata to the
proportionate part of a tax year as to Taxes, and calendar year, as to Building
Expenses, in which this Lease begins or ends, for the portion of each such year
during which this Lease is in effect. Such obligation to make payments of such
additional rent shall survive the expiration or sooner termination of the Term,
whether or not this Lease is superseded by a subsequent lease of the Premises
or of any other space or Tenant leaves the Building; any such superseding lease
shall not serve to supersede Tenants obligation for any such additional
rent unless it makes express reference thereto and recites that such additional
rent is abated in consideration of the superseding lease.


5.6 Payments. All payments or
installments of any rent hereunder and all sums whatsoever due under this Lease
(including but not limited to court costs and attorneys fees) shall be deemed
rent, shall be paid to Landlord at the address designated by Landlord, and if
not paid when due, shall be subject to a late charge of $35.00 for each late
payment and shall bear interest at the rate of 13% per annum (but not more than
the maximum allowable legal rate applicable to Tenant) until paid.
Additionally, if any of Tenants checks for payment of rent or additional
rent are returned to Landlord for insufficient funds, Tenant shall pay to
Landlord as additional rent $50.00 for each such check returned for
insufficient funds, and if two or more of Tenants checks in payment of
rent or additional rent due hereunder are returned for insufficient funds in
any calendar year, Landlord reserves the right upon ten (10) days advance
written notice to Tenant to thereafter require Tenant to pay all rent and
additional rent and other sums whatsoever due under this Lease by money order
or by certified check or cashiers check. Time is of the essence in this
Lease.


6. Requirements of Applicable Law. Landlord warrants that on
the Commencement Date, the Premises will comply with all applicable laws,
ordinances, rules and regulations of governmental authorities having
jurisdiction over the Property (Applicable Laws). Tenant, at its
sole cost and expense, shall thereafter comply promptly with all Applicable
Laws now in force or which may hereafter be in force, which impose any duty
upon Landlord or Tenant with respect to the use, occupancy or alteration of the
Premises or any part thereof and for the prevention of fires provided that such
compliance is necessitated by Tenants use; provided, however, that Landlord,
at Landlords expense, and not Tenant shall correct all structural defects and
make all improvements that are capital in nature in the Building necessary to
comply with Applicable Laws, and make all repairs, changes or alterations
necessary because the Building was not constructed in compliance with any of
said Applicable Laws.
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|7. Certificate of Occupancy. Tenant will not use or occupy the
Premises in violation of any certificate of occupancy, permit, or other
governmental consent issued for the Building. If any governmental authority,
after the commencement of the Term, shall contend or declare that the Premises
are being used for a purpose which is in violation of such certificate of
occupancy, permit, or consent, then Tenant shall, upon five (5) days written
notice from Landlord, immediately discontinue or continue to use the Premises
subject to Section 8 below. If thereafter the governmental authority asserting
such violation threatens, commences or continues criminal or civil proceedings
against Landlord for Tenants failure to discontinue such use, in addition
to any and all rights, privileges and remedies given to Landlord under this
Lease for default therein, Landlord shall have the right to terminate this
Lease forthwith. Tenant shall indemnify and hold Landlord harmless of and from
any and all liability for any such violation or violations.


8. Contest-Statute, Ordinance, Etc. Tenant may, after written
notice to Landlord, by appropriate proceedings conducted promptly at Tenants
own expense in Tenants name and whenever necessary in Landlords
name, contest in good faith the validity or enforcement of any such statute,
ordinance, law, order, regulation or requirement and may similarly contest any
assertion of violation of any certificate of occupancy, permit, or any consent
issued for the Building. Tenant may, pending such contest, defer compliance
therewith if, in the reasonable opinion of counsel for Landlord, such deferral
will not subject either the Landlord or the Premises or the Property (or any
part thereof) to any penalty, fine or forfeiture, and if Tenant shall post a
bond with corporate surety approved by Landlord sufficient, in Landlords
reasonable opinion, fully to indemnify Landlord from loss.


9. Tenants Improvements. Except to the extent that
Landlord is responsible for making improvements to the Premises pursuant to
Sections 10.2 and/or 34 of this Lease, Tenant agrees that it will make such
improvements to the Premises as it may deem necessary at its sole cost and
expense. Tenant shall not make any alterations, decorations, installations,
additions or improvements to the Premises, including but not limited to, the
installation of any fixtures, amenities, equipment, appliances, or other
apparatus which has a material adverse affect on the structure of the Building
or which would preclude Tenant from complying with its obligations upon the
surrender of the Premises at the expiration or sooner termination of the Term
in accordance with the express terms of this Lease, without Landlords
prior written consent (which consent shall not be unreasonably withheld), and
then only by contractors or mechanics employed or approved by Landlord. All
such work, alterations, decorations, installations, additions or improvements
shall be done at Tenants sole expense and at such times and in such
manner as Landlord may from time to time reasonably designate upon mutual
agreement with Tenant. Landlords consent to and/or approval of Tenants
plans and specifications for the aforesaid improvements shall create no
responsibility or liability on the part of Landlord for their completeness,
design sufficiency, or compliance with all laws, rules and regulations of
governmental agencies or authorities. All alterations, decorations,
installations, additions or improvements made by either of the parties hereto
upon the Premises, except movable office furniture, trade fixtures, equipment,
including hardware and systems, and other components which may be removed
without an adverse affect on Tenants compliance with its obligations upon the
surrender of the Premises at the expiration or sooner termination of the Term
in accordance with the express terms of this Lease, which were put in at the
expense of Tenant and other items as mutually agreed upon in writing, shall be
the property of Landlord and shall remain upon and be surrendered with the
Premises at the termination of this Lease without molestation or injury.
Notwithstanding anything herein to the contrary, at the expiration or sooner
termination of the Term, Tenant, at Tenants expense, shall have the right to
remove the generator installed by Tenant on the exterior of the Building, the
UPS (uninterrupted power source equipment), the supplemental fire suppression
system, the PDU (the power distribution units), raised flooring, the
supplemental HVAC system, the data and telecommunications and telephone cabling
and cable trays installed by the Tenant in the Premises (the Removal Items);
provided, however, that (i) if Tenant elects to leave any of the Removal Items
in the Second Floor Key Area, the exterior of the Building or in the area shown
on Exhibit F attached hereto and made a part hereof (collectively, the
Second Floor Key Area), as the case may be, and Landlord desires to have any
of such Removal Items removed from such area(s), Landlord shall have the right
to remove such Removal Items and Tenant shall reimburse Landlord within thirty
(30) days after receipt of a written invoice for the removal costs, together
with reasonable supporting evidence, and (ii) if Tenant removes any of such
Removal Items from the Second Floor Key Area, Tenant, at Tenants expense,
shall restore the ceiling to a nine foot (9) finished condition, with a
reasonable amount of ceiling lights and with the concrete floor slab in tact;
provided, however, that prior to the Commencement Date, Landlord shall have
installed sufficient wiring so that no additional wiring is required in order
for Tenant to comply with this Subsection 9(ii). Notwithstanding anything
herein to the contrary, Landlord, at Tenants expense, shall have the right to
restore the ceiling in the Second Floor Key Area to a nine foot (9)
height including sprinkler heads, provided that Landlord, at Landlords
expense, shall install the ductwork to the area of the data and
telecommunications center.

|10. Repairs and Maintenance.



10.1 Tenants Care of the
Premises and Building. During the Term Tenant shall:
|--------------------------------------------------------------------------------------------------------------

good order and condition;
| | --------------------------------------------------------------------------------------------------------------

| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 10.1.3
repair and replace special equipment or decorative treatments installed by or

| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 10.1.4
pay for all damage to the Building, its fixtures and appurtenances, as well as

| | 10.1.5
In the event that Tenant should require supplemental HVAC for the Premises, any
maintenance repair and/or replacement required for such supplemental service
shall be performed by Tenant.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|In addition Tenant shall not
place a load upon any floor of the Premises exceeding the floor load per square
foot area which such floor was designed to carry and which may be allowed under
Applicable Laws. Landlord represents that the load of the floor in the entire
Premises is 100 pounds per square foot. Tenant, at Tenants expense, shall have
the right to increase the load of the floor in the Second Floor Key Area to
accomodate 150 pounds per square foot. Landlord reserves the right to
reasonably prescribe, in order not to exceed the maximum load, the weight and
position of all heavy equipment brought onto the Premises and prescribe any
reinforcing required under the circumstances, all such reinforcing to be at
Tenants expense.
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|10.2 Landlords Repairs.
Except for the repairs and replacements that Tenant is required to make
pursuant to Section 10.1 above, Landlord shall make all other repairs and
replacements to the Premises, Common Areas and Building (including Building
fixtures and equipment) as shall be reasonably deemed necessary to maintain the
Building in a condition comparable to other first class suburban office
buildings in the Baltimore-Washington corridor area. This maintenance shall
include, without limitation, the roof, foundation, exterior walls, interior
structural walls, all structural components, and all systems such as
mechanical, electrical, multi-tenant HVAC, and plumbing. The costs associated
with such repairs shall be deemed a part of Building Expenses; provided,
however, that costs of all of such repairs which would be considered capital in
nature under generally accepted accounting principles shall be paid by
Landlord. There shall be no allowance to Tenant for a diminution of rental
value, no abatement of rent, and no liability on the part of Landlord by reason
of inconvenience, annoyance or injury to business arising from Landlord, Tenant
or others making any repairs or performing maintenance as provided for herein
unless Landlord fails to use its reasonable efforts to coordinate its
performance with Tenant and to avoid such inconvenience, annoyance or injury.
Landlord shall provide Tenant with a contact person and pager number for the
property manager of the Building which is activated twenty-four (24) hours per
day and in emergency situations shall use reasonable efforts to provide repairs
and replacements on an emergency basis.


10.3 Time for Repairs. Repairs or
replacements required pursuant to Section 10.1 and 10.2 above shall be made
within a reasonable time (depending on the nature of the repair or replacement
needed - generally no more than seven (7) days) after receiving written notice
or having actual knowledge of the need for a repair or replacement subject to
Section 10.2 above. In the event of an emergency situation for a repair which
is Landlords responsibility hereunder, Tenant shall use its reasonable efforts
to notify Landlord of the need for such repair; provided, however, if Tenant is
unable to notify Landlord and has reason to believe that failing to act
immediately will result in irreparable harm or diminution of value to Tenant,
the Building, the Premises or the personal property located in the Premises,
then Tenant shall have the right to make such repair and Landlord shall
reimburse Tenant for the actual costs incurred by Tenant within thirty (30)
days after receipt of a written invoice from Tenant, together with reasonable
supporting documentation.


10.4 Surrender of the Premises.
Upon the termination of this Lease, Tenant shall surrender the Premises to
Landlord in the same broom clean condition that the Premises were in on the
Commencement Date except for:

| | 10.4.1
ordinary wear and tear;
| | ------------------------------

Tenant; and
| | -------------------------------------------------------------------------------------------

| | 10.4.4
alterations as permitted by this Lease unless consent was conditioned on their
removal.
| | ----------------------------------------------------------------------------------------------

|On surrender, Tenant shall remove
from the Premises its personal property, trade fixtures and any alterations
required to be removed pursuant to the terms of this Lease and repair any
damage to the Premises caused by this removal unless otherwise agreed by Tenant
and Landlord. Any items not removed by Tenant as required above shall be
considered abandoned unless otherwise agreed by Tenant and Landlord. Landlord
may dispose of abandoned items as Landlord chooses and bill Tenant for the net
cost of their disposal.


11. Conduct on Premises. Tenant shall not do, or permit
anything to be done in the Premises, or bring or keep anything therein which
will, in any way, increase the rate of fire insurance on the Building, or
invalidate or conflict with the fire insurance policies on the Building,
fixtures or on property kept therein, or obstruct or interfere with the rights
of the Landlord or of other tenants, or in any other way injure or annoy
Landlord or the other tenants, or subject Landlord to any liability for injury
to persons or damage to property, or interfere with the good order of the
Building, or conflict with Applicable Laws, or the Maryland Fire Underwriters
Rating Bureau. Tenant agrees that any increase of fire insurance premiums on
the Building or contents caused by the occupancy of Tenant and any expense or
cost incurred in consequence of negligence or carelessness or the willful
action of Tenant, Tenants employees, agents, servants, or invitees shall,
as they accrue be added to the rent heretofore reserved and be paid as a part
thereof provided that such increase in costs is not the result of actions by
Landlord or other tenants; and Landlord shall have all the rights and remedies
for the collection of same as are conferred upon the Landlord for the
collection of rent provided to be paid pursuant to the terms of this Lease.
Notwithstanding anything herein to the contrary, as of the Commencement Date,
Landlord represents that the generator which Tenant intends to install as part
of its improvements will not cause an increase in any premiums described in
this Section.
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|12. Insurance.
|--------------

| | 12.1
Tenants Insurance. Tenant will keep in force at its own expense, so long
as this Lease remains in effect, (a) public liability insurance with respect to
the Premises, to afford protection with limits, per person and for each
occurrence, of not less than Two Million Dollars ($2,000,000), combined single
limit, with respect to personal injury and death and property damage, such
insurance to provide for only a reasonable deductible, (b) all-risk property
and casualty insurance, including theft, written at replacement cost value and
with replacement cost endorsement, covering all of Tenants personal
property in the Premises and all improvements and installed in the Premises by
or on behalf of Tenant whether pursuant to the terms of Section 34, Section 9,
or otherwise, such insurance to provide for only a reasonable deductible, and
(c) if, and to the extent, required by law, workmens compensation or
similar insurance offering statutory coverage and containing statutory limits.
Such policies will be maintained in companies rated in Bests Insurance Guide
at least A as to general policyholder rating and at least Class X as to
financial strength and in a form which is consistent with common insurance
industry practice and will be written as primary policy coverage and not
contributing with, or in excess of, any coverage which Landlord shall carry.
Upon request from Landlord, Tenant will deposit the policy or policies of such
required insurance or certificates thereof with Landlord prior to the
Commencement Date, which policies shall name Landlord or its designee and, at
the request of Landlord, its mortgagees, as additional insured and shall also
contain a provision stating that such policy or policies shall not be canceled
except after thirty (30) days written notice to Landlord or its
designees. All such policies of insurance shall be effective as of the date
Tenant occupies the Premises and shall be maintained in force at all times
during the Term of this Lease and all other times during which Tenant shall
occupy the Premises. In addition to the foregoing insurance coverage, Tenant
shall require any contractor retained by it to perform work on the Premises to
carry and maintain, at no expense to Landlord, during such times as contractor
is working in the Premises, a non-deductible (i) comprehensive general
liability insurance policy, including, but not limited to, contractors
liability coverage, contractual liability coverage, completed operations
coverage, broad form property damage endorsement and contractors
protective liability coverage, to afford protection with limits per person and
for each occurrence, of not less than Two Hundred Thousand Dollars
($200,000.00), combined single limit, with respect to personal injury and death
and property damage, such insurance to provide for no deductible, and (ii)
workmens compensation insurance or similar insurance in form and amounts
as required by law. In the event of damage to or destruction of the Premises
and the termination of this Lease by Landlord pursuant to Section 17 herein,
Tenant agrees that it will pay Landlord all of its insurance proceeds for
improvements made in the Premises by or on behalf of Tenant whether pursuant to
the terms of Section 34, Section 9, or otherwise, excluding, however, those
insurance proceeds allocated to those items which Tenant is permitted to remove
from the Premises at the expiration or sooner termination of the Term. If
Tenant fails to comply with its covenants made in this Section, if such
insurance would terminate or if Landlord has reason to believe such insurance
is about to be terminated, Landlord may at its option cause such insurance as
it in its sole judgment deems necessary to be issued, and in such event Tenant
agrees to pay promptly upon Landlords demand, as additional rent the
premiums for such insurance.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|12.2 Landlords Insurance.
Landlord will keep in force at its own expense (a) contractual and
comprehensive general liability insurance, including public liability and
property damage, with a minimum combined single limit of liability per person
and for each occurrence, of Two Million Dollars ($2,000,000.00) for personal
injuries or death of persons occurring in or about the Building and Premises,
and (b) all-risk property and casualty insurance written at replacement cost
value covering the Building and all of Landlords improvements in and
about same. Such policies will be maintained in companies rated in Bests
Insurance Guide at least  A as to general policyholder rating and at least
Class X as to financial strength and in a form which is consistent with common
insurance industry practice and will be written as primary policy coverage and
not contributing with, or in excess of, any coverage with Landlord shall carry.


12.3 Waiver of Subrogation. Each
party hereto waives claims arising in any manner in its favor and against the
other party and agrees that neither party hereto shall be liable to the other
party or to any insurance company (by way of subrogation or otherwise) insuring
the other party for any loss or damage to the Building, the Premises or other
tangible property, or any resulting loss of income, or losses under workers
compensation laws and benefits, or against liability on or about the Building,
even though such loss or damage might have been occasioned by the negligence of
such party, its agents or employees if any such loss or damage is covered by
insurance benefiting the party suffering such loss or damage as was required to
be covered by insurance carried pursuant to this Lease. Landlord shall cause
each insurance policy carried by it insuring against liability on or about the
Building or insuring the Premises and the Building or income resulting
therefrom against loss by fire or any of the casualties covered by the all-risk
insurance carried by it hereunder to be written in such a manner as to provide
that the insurer waives all right of recovery by way of subrogation against
Tenant in connection with any loss or damage covered by such policies. Tenant
will cause each insurance policy carried by it insuring against liability or
insuring the Premises (including the contents thereof and Tenants
Improvements installed therein by Tenant or on its behalf) against loss by fire
or any of the casualties covered by the all-risk insurance required hereunder
to be written in such a manner as to provide that the insurer waives all right
of recovery by way of subrogation against Landlord in connection with any loss
or damage covered by such policies.
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|13. Rules and Regulations. Tenant agrees to be bound by the
rules and regulations set forth on the schedule attached hereto as Exhibit
B and made a part hereof. Landlord shall have the right, from time
to time, to issue additional or amended rules and regulations regarding the use
of the Building, so long as said rules shall be reasonable and
non-discriminatory between tenants and that such rules and regulations are
consistent with the permitted use of the Premises by the Tenant as specified
herein. When so issued the same shall be considered a part of this Lease and
Tenant covenants that said additional or amended rules and regulations shall
likewise be faithfully observed by Tenant, the employees of Tenant and all
persons invited by Tenant into the Building, provided, that said additional or
amended rules are made applicable to all office tenants similarly situated as
Tenant. Landlord shall not be liable to Tenant for the violation of any of the
said rules and regulations, or the breach of any covenant or condition in any
lease, by any other tenant in the Building. In the event of a conflict between
the rules/regulations and the Lease, the terms of the Lease shall govern the
situation.


14. Mechanics Liens. Tenant shall not do or suffer to be
done any act, matter or thing whereby Tenants interest in the Premises,
or any part thereof, may be encumbered by any mechanics lien. Tenant
shall discharge, within ten (10) days after the date of filing, any mechanics liens
purporting to be for labor or material furnished or to be furnished to Tenant.
Landlord shall not be liable for any labor or materials furnished or to be
furnished to Tenant upon credit, and no mechanics or other lien for labor
or materials shall attach to or affect the reversionary or other estate or
interest of Landlord in and to the Premises, or the Property.


Landlord shall discharge, within
ten (10) days after the date of filing, any mechanics liens filed purporting
to be for labor or material furnished or to be furnished to Landlord. Tenant
shall not be liable for any labor or materials furnished or to be furnished to
Landlord upon credit.



15. Failure to Repair. In the event that either Landlord or
Tenant fails after reasonable prior written notice from the other party, to
keep the Premises in a good state of condition and repair pursuant to Section
10 above, or to do any act or make any payment required under this Lease or
otherwise fails to comply herewith, such party may, at its option (but without
being obliged to do so) immediately, or at any time thereafter and without
notice, perform the same for the account of the responsible party, including
the right to enter upon the Premises at all reasonable hours (subject to
Section 28 below) to make such repairs, or do any act or make any payment or
compliance which the responsible party has failed to do, and upon demand, the
responsible party shall reimburse such party for any such expense incurred by
such party including but not limited to any costs and damages. Any moneys
expended by Landlord, as aforesaid, shall be deemed additional rent,
collectible as such by Landlord. All rights given to either party in this
Section shall be in addition to any other right or remedy of such party herein
contained.


16. Property  Loss, Damage. Landlord, its agents and
employees shall not be liable to Tenant for (i) any damage or loss of property
of the Tenant placed in the custody of persons employed to provide services for
or stored in or about the Premises and/or the Building, unless such damage or
loss is the result of the negligence of Landlord, and (ii) interference with
the light, air, or other incorporeal hereditaments of the Premises.


17. Destruction  Fire or Other Casualty. In case of partial
damage to the Premises by fire or other casualty insured against by Landlord,
Tenant shall give immediate notice (either oral or written) thereof to
Landlord, who shall thereupon cause damage to all property owned by it to be
repaired with reasonable speed at expense of Landlord, due allowance being made
for reasonable delay which may arise by reason of adjustment of loss under
insurance policies on the part of Landlord and/or Tenant, and for reasonable
delay on account of labor troubles or any other cause beyond
Landlords control, and to the extent that the Premises are rendered
untenantable the rent shall proportionately abate from the date of such
casualty, provided the damage above mentioned occurred without the fault or
neglect of Tenant, Tenants servants, employees, agents or visitors. If
such partial damage is due to the fault or neglect of Tenant, or Tenants
servants, employees, agents, or invitees, the damage shall be repaired by
Landlord to the extent of Landlords insurance coverage, but there shall
be no apportionment or abatement of rent. In the event the damage shall be so
extensive to the whole Building as to render it uneconomical, in Landlords
opinion, to restore for its present uses and Landlord shall decide not to
repair or rebuild the Building, this Lease, at the option of Landlord, shall be
terminated upon written notice to Tenant and the rent shall, in such event, be
paid to or adjusted as of the date of such damage, and the terms of this Lease
shall expire by lapse of time and conditional limitation upon the third day
after such notice is mailed, and Tenant shall thereupon vacate the Premises and
surrender the same to Landlord, but no such termination shall release Tenant
from any liability to Landlord arising from such damage or from any breach of
the obligations imposed on Tenant hereunder, or from any obligations accrued
hereunder prior to such termination. If Landlord estimates that it will take
(i) at least 180 days from the date of the casualty to complete all repairs
required to restore the areas of the Building which do not have raised flooring
or (ii) 120 days from the date of the casualty to complete in the case of the
Second Floor Key Area, Tenant shall have the right to terminate this Lease by
giving Landlord written notice of termination within thirty (30) days after
receipt of Landlords notice of the completion time. Landlord shall notify
Tenant of the estimated time required to complete the repairs on or before that
date which is forty-five (45) days after the date of the casualty.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|18. Eminent Domain. If (1) so much of the Premises shall be
taken or condemned by Eminent Domain for any public or quasi-public use or
purpose and either party determines that Tenants use of the Premises will be
materially and adversely affected, and either party shall elect, by giving
written notice to the other, or (2) more than twenty-five percent (25%) of the
floor area of the Building shall be so taken, and Landlord shall elect, in its
sole discretion, by giving written notice to the Tenant, any said written
notice to be given not more than sixty (60) days after the date on which title
shall vest in such condemnation proceeding, to terminate this Lease, then, in
either such event, the Term of this Lease shall cease and terminate as of the
date of title vesting. Notwithstanding anything in subsection (1) of the
immediately preceding sentence to the contrary, if Landlord exercises its
termination rights, Tenant shall have the right to abrogate and void Landlords
termination notice by affirming its obligations under the Lease by delivering a
written notice to Landlord within fifteen (15) days after receipt of Landlords
termination notice. In case of any taking or condemnation, whether or not the
Term of this Lease shall cease and terminate, the entire award shall be the
property of Landlord, and Tenant hereby assigns to Landlord all its right,
title and interest in and to any such award, except that Tenant shall be
entitled to claim, prove and receive in the proceedings such awards as may be
allowed for moving expenses, loss of profit and fixtures and other equipment
installed by it which shall not, under the terms of this Lease, be or become
the property of Landlord at the termination hereof, but only if such awards
shall be made by the condemnation, court or other authority in addition to, and
be stated separately from, the award made by it for the Property or part
thereof so taken. Landlord shall notify Tenant within five (5) business days
after receipt of a written notice of a taking or threatened taking of all or
any portion of the Building or the Premises.
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|19. Assignment. So long as Tenant is not in default of any of
the terms and conditions hereof, and further provided that Tenant has fully and
faithfully performed all of the terms and conditions of this Lease, Landlord
will not unreasonably withhold its consent to an assignment of this Lease or
sublease of the Premises for any of the then remaining portion of the unexpired
Term provided: (i) the net assets of the assignee or sublessee shall be
satisfactory to Landlord in its reasonable discretion; (ii) in the event of an
assignment, such assignee shall assume in writing all of Tenants
obligations under this Lease; (iii) in the event of a sublease, such sublease
shall in all respects be subject to and in conformance with the terms of this
Lease; and (iv) in all events Tenant continues to remain liable on this Lease
for the performance of all terms, including but not limited to, payment of all
rent due hereunder. Landlord and Tenant acknowledge and agree that it shall not
be unreasonable for Landlord to withhold its consent to an assignment if in
Landlords reasonable judgment, the assignee lacks sufficient business
experience or net worth to successfully operate its business within the
Premises in accordance with the terms, covenants and conditions of this Lease.
If this Lease be assigned, or if the Premises or any part thereof be underlet
or occupied by anybody other than Tenant, Landlord may, after default by
Tenant, collect rent from the assignee, undertenant or occupant and apply the
net amount collected to the rent herein reserved, but no such collection shall
be deemed a waiver of this covenant, or the acceptance of the assignee,
undertenant or occupant as tenant, or a release of Tenant from the further
observance and performance by Tenant of the covenants herein contained. For
purposes of the foregoing, a transfer of a controlling interest in Tenant as
same exists as of the date hereof, shall be deemed to be an assignment of this
Lease. No assignment or sublease, regardless of whether Landlords consent
has been granted or withheld, shall be deemed to release Tenant from any of its
obligations.


Notwithstanding anything herein
to the contrary, (i) if Tenant is a publicly-traded corporation, no consent
shall be required for a transfer of the controlling interest(s) of Tenant, and
(ii) no consent shall be required for a assignment or subletting to a
wholly-owned subsidiary of Tenant, provided that Tenant shall notify Landlord
in advance of such event.


20. Default; Remedies; Bankruptcy of Tenant. Any one or more of
the following events shall constitute an Event of Default hereunder,
at Landlords election: (a) the sale of Tenants interest in the
Premises under attachment, execution or similar legal process or, the
adjudication of Tenant as a bankrupt or insolvent, unless such adjudication is
vacated within thirty (30) days; (b) the filing of a voluntary petition
proposing the adjudication of Tenant as a bankrupt or insolvent, or the
reorganization of Tenant, or an arrangement by Tenant with its creditors,
whether pursuant to the Federal Bankruptcy Code or any similar federal or state
proceeding, unless such petition is filed by a party other than Tenant and is
withdrawn or dismissed within ninety (90) days after the date of its filing;
(c) the admission, in writing, by Tenant of its inability to pay its debts when
due; (d) the appointment of a receiver or trustee for the business or property
of Tenant, unless such appointment is vacated within thirty (30) days of its
entry; (e) the making by Tenant of an assignment for the benefit of its
creditors, or if, in any other manner, Tenants interest in this Lease
shall pass to another by operation of law; (f) the failure of Tenant to pay any
rent, additional rent or other sum of money when due and such failure continues
for a period of twelve (12) days after receipt of written notice that the same
is past due hereunder; (g) the Tenant shall fail to move into or take
possession of the Premises within thirty (30) days after commencement of the
Term or having taken possession shall thereafter abandon and/or vacate the
Premises, and (h) the default by Tenant in the performance or observance of any
covenant or agreement of this Lease (other than a default involving the payment
of money), which default is not cured within thirty (30) days after the giving
of written notice thereof by Landlord, unless such default is of such nature
that it cannot reasonably be cured within such thirty (30) day period, in which
case no Event of Default shall occur so long as Tenant shall commence the
curing of the default within such thirty (30) day period and shall thereafter
diligently prosecute the curing of same.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|Upon the occurrence and
continuance of an Event of Default, Landlord, upon written notice to Tenant as
provided for by law or as expressly provided for herein (whichever provides
greater notice to Tenant), may do any one or more of the following: (a) after a
formal legal proceeding, sell, at public or private sale, all or any part of
the goods, chattels, fixtures and other personal property belonging to Tenant
which are or may be put into the Premises during the Term, whether or not
exempt from sale under execution or attachment , and apply the proceeds of such
sale, first, to the payment of all costs and expenses of conducting the sale or
caring for or storing said property; second, toward the payment of any
indebtedness, including, without limitation, indebtedness for rent, which may
be or may become due from Tenant to Landlord; and third, to pay the Tenant, on
demand in writing, any surplus remaining after all indebtedness of Tenant to
Landlord has been fully paid; (b) perform, on behalf and at the expense of
Tenant, any obligation of Tenant under this Lease which Tenant has failed to
perform and of which Landlord shall have given Tenant written notice, the cost
of which performance by Landlord, together, with interest thereon at the rate
of thirteen percent (13%) per annum, from the date of such expenditure, shall
be deemed additional rent and shall be payable by Tenant to Landlord upon
demand; (c) elect to terminate this Lease and the tenancy created hereby by
giving written notice of such election to Tenant, in which event Tenant shall
be liable for Base Rent, additional rent, and other indebtedness that otherwise
would have been payable by Tenant during the remainder of the Term had there
been no Event of default, and on written notice reenter the Premises, by
summary proceedings, and remove Tenant and all other persons and property from
the Premises, and store such property in a public warehouse or elsewhere at the
cost and for the account of Tenant, without Landlord being deemed guilty of
trespass or becoming liable for any loss or damage occasioned thereby; and also
the right, but not the obligation, to re-let the Premises for any unexpired
balance of the Term, and collect the rent therefor. In the event of such
re-letting by Landlord, the re-letting shall be on such terms, conditions and
rental as Landlord may deem proper, and the proceeds that may be collected from
the same, less the expense of re-letting (including reasonable leasing fees and
commissions and reasonable costs of renovating the Premises, but specifically
excluding in-house attorneys fees), shall be applied upon the Tenants
rental obligation as set forth in this Lease for the unexpired portion of the
Term. Tenant shall be liable for any balance that may be due under this Lease,
although Tenant shall have no further right of possession of the Premises; and
(d) exercise any other legal or equitable right or remedy which it may have at
law or in equity. Notwithstanding the provisions of clause (b) above and
regardless of whether an Event of Default shall have occurred, Landlord may
exercise the remedy described in clause (b) without any notice to Tenant if
Landlord, in its good faith reasonable judgment, believes it would be
materially injured by the failure to take rapid action, or if the unperformed
obligation of Tenant constitutes an emergency.


To the extent permitted by law,
Tenant hereby expressly waives any and all rights of redemption, granted by or
under any present or future laws in the event of Tenants being evicted or
dispossessed for any cause, or in the event of Landlords obtaining
possession of the Premises, by reason of the violation by Tenant of any of the
covenants and conditions of this Lease. Landlord and Tenant hereby expressly
waive trial by jury in any action or proceeding or counterclaim brought by
either party hereto against the other party on any and every matter, directly
or indirectly arising out of or with respect to this Lease, including, without
limitation, the relationship of Landlord and Tenant, the use and occupancy by
Tenant of the Premises, any statutory remedy and/or claim of injury or damage
regarding this Lease.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|Any costs and expenses incurred
by Landlord or Tenant (including, without limitation, reasonable attorneys fees)
in enforcing any of its rights or remedies under this Lease shall be deemed to
be additional rent (if Tenant is the non-prevailing party) and shall be repaid
by the non-prevailing party in a legal proceeding upon the earlier of (i) that
date set by the court in the legal proceeding or (ii) within thirty (30) days
after the completion of the legal proceeding.



Notwithstanding any of the other
provisions of this Lease, in the event Tenant shall voluntarily come under the
jurisdiction of the Federal Bankruptcy Code or involuntarily come under the
jurisdiction of the Federal Bankruptcy Code if the petition is not dismissed
within ninety (90) days after the date of filing Tenant or its trustee in
bankruptcy, under the authority of and pursuant to applicable provisions
thereof, shall have the power and so using same determine to assign this Lease,
Tenant agrees that (i) Tenant or its trustee will provide to Landlord
sufficient information enabling it to independently determine whether Landlord
will incur actual and substantial detriment by reason of such assignment and
(ii) adequate assurance of future performance under this Lease, as
that term is generally defined under the Federal Bankruptcy Code, will be
provided to Landlord by Tenant and its assignee as a condition of said
assignment.


21. Damages. If this Lease is terminated by Landlord pursuant
to Section 20, Tenant shall, nevertheless, remain liable for all rent and
damages which may be due or sustained prior to such termination, and all
reasonable costs, fees and expenses including, but not limited to, attorneys fees
if Landlord is the prevailing party in a legal proceeding, costs and expenses
incurred by Landlord in pursuit of its remedies hereunder, or in renting the
Premises to others from time to time and additional damages (the Liquidated
Damages), which shall be an amount equal to the total rent which, but for
termination of this Lease, would have become due during the remainder of the
Term, less the amount of rent, if any, which Landlord shall receive 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), in which case such
Liquidated Damages shall be computed and payable in monthly installments, in
advance on the first day of each calendar month following termination of the
Lease and continuing until the date on which the Term would have expired but
for such termination, and any suit or action brought to collect any such
Liquidated Damages for any month shall not in any manner prejudice the right of
Landlord to collect any Liquidated Damages for any subsequent month by a
similar proceeding.


If this Lease is terminated
pursuant to Section 20, Landlord may relet the Premises or any part thereof,
alone or together with other premises, for such term(s) which may be greater or
less than the period which otherwise would have constituted the balance of the
Term and on such terms and conditions (which may include concessions, free rent
and/or alterations of the Premises) as Landlord, in its sole 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 the Premises or any failure by Landlord to collect any rent due upon such
reletting.
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|22. Services and Utilities. Landlord shall provide the
following listed services and utilities, namely:
|-------------------------------------------------------------------------------------------------------

| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Notwithstanding
the foregoing, if at any time during the Term, Landlord shall, after reasonable
investigation determine that trash and similar waste generated by Tenant and/or
emanating from the Premises is in excess of that of other standard office and
data center tenants within the Building leasing a premises of the same or
similar size to that of the Premises, Landlord shall bill Tenant and Tenant
shall pay to Landlord as additional rent hereunder within thirty (30) days of
the date of Landlords invoice for the same, those costs and expenses of
trash removal which are reasonably attributable to such excess trash and
similar waste generated by Tenant and/or emanating from the Premises. Landlord
shall use reasonable efforts to perform the services and provide the utilities
required under this Section 22 in a manner which avoids inconvenience,
annoyance or injury to Tenant. Landlord reserves the right to stop service of
the HVAC, elevator, plumbing and electric systems, when necessary, by reason of
accident, or emergency, or for repairs, alterations, replacements, or
improvements, which in the judgment of Landlord are desirable or necessary to
be made, until said repairs, alterations, replacements, or improvements shall
have been completed with due diligence and reasonable efforts by Landlord;
provided, however, that Landlord shall make all reasonable efforts to avoid
such stoppage, and, if such stoppage nonetheless is required, to coordinate
with Tenant and avoid inconvenience, annoyance or injury to Tenant arising out
of the stoppage. Landlord shall have no responsibility or liability for failure
to supply HVAC, elevator, plumbing, cleaning, and electric service, during said
period or when prevented from so doing by laws, orders, or regulations of any
Federal, State, County or Municipal authority or by strikes, accidents or by
any other cause whatsoever beyond Landlords control. Landlords
obligations to supply HVAC are subject to applicable laws and regulations as to
energy conservation and other such restrictions. In the event that Tenant
should require supplemental HVAC for the Premises, any maintenance repair
and/or replacement required for such supplemental service shall be performed by
Landlord but the cost of such maintenance repair and/or replacement (including
labor and materials) shall be paid by Tenant as additional rent.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|23. Electric Current. Landlord has supplied or will supply the
Premises with the necessary lines to provide electric service to the Premises
for normal office and data center operations, as well as separate meters so
that Tenants consumption of electric power can be separately measured and
charged to Tenant. Tenant shall pay all charges (including meter installation
and adjustment) for electric and similar utilities or services so supplied
directly to the utility company supplying same when due and before penalties or
late charges on same shall accrue. Tenant shall not at any time overburden or
exceed the capacity of the mains, feeders, ducts, conduits, or other facilities
by which electric and similar utilities are supplied to, distributed in or
serve the Premises. If Tenant desires to install any equipment which shall
require additional electric or similar facilities of a greater capacity than as
provided by Landlord, such installation shall be subject to Landlords
prior written approval of Tenants plans and specifications therefor,
which approval shall not be unreasonably withheld. If such installation is
approved by Landlord, all costs for providing such additional electrical and
similar facilities shall be paid by Tenant.


24. Telephone. Landlord has arranged for the installation of
telephone service within the Building. Tenant shall be responsible for
contacting the utility company supplying said telephone service and arranging
to have such telephone facilities as it may desire to be extended from the main
telephone room on the first floor of the Building and put into operation in the
Premises. Tenant acknowledges and agrees that all telephone and
telecommunications services desired by Tenant shall be ordered and utilized at
the sole expense of Tenant. All costs related to installation and the provision
of such service shall be borne and paid for directly by Tenant.


In the event Tenant wishes to
utilize the services of a telephone or telecommunications provider whose
equipment is not servicing the Building at such time Tenant wishes to install
its telecommunications equipment serving the Premises (Provider),
no such Provider shall be permitted to install its lines or other equipment
without first securing the prior written consent of Landlord, which consent
shall not be unreasonably withheld. Prior to the commencement of any work in or
about the Building by the Provider, the Provider shall agree to abide by such
rules and regulations, job site rules, and such other requirements as
reasonably determined by Landlord to be necessary to protect the interest of
the Building and Property, the other tenants and occupants of the Building and
the Landlord, including, without limitation, providing security in such form
and amount as reasonable determined by Landlord. Each Provider must be duly
licensed, insured and reputable. Landlord shall incur no expense whatsoever
with respect to any aspect of Providers provision of its services,
including without limitation, the costs of installation, materials and service.


25. Acceptance of Premises. Tenant and Tenants consultants
shall have reasonable opportunity prior to the Commencement Date, to examine
the Premises to determine the condition thereof and to commence construction of
the work to be performed by Tenant in the Premises, provided it does not
thereby interfere with Landlords Work. If Tenant or Tenants consultant
identify a potential problem or question upon examination of the Premises prior
to the Commencement Date, Tenant shall notify Landlord and the parties shall
use their reasonable effort to agree on a mutually acceptable solution. Tenant
shall notify Landlord prior to entering the Premises of the names of two (2)
representatives who are authorized to communicate with the Landlord regarding
the condition of the Premises. Upon taking possession and occupancy of the
Premises, Tenant shall be deemed to have accepted same as being satisfactory
and in the condition called for hereunder, except for latent defects and punch
list items noted to Landlord in accordance with Section 2.2 above.
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|26. Inability to Perform. After the Commencement Date has
occurred, this Lease and the obligation of Tenant to pay rent hereunder and the
obligation of either party to perform all of the other covenants and agreements
hereunder on the part of such party to be performed shall in no way be
affected, impaired or excused because either party is unable to fulfill any of
its obligations under this Lease or to supply, or is delayed in supplying, any
service to be supplied by it under the terms of this Lease or is unable to
make, or is delayed in making any repairs, additions, alterations, or
decorations or is unable to supply, or is delayed in supplying, any equipment
or fixtures if either party is prevented or delayed from so doing by reason of
strikes or labor troubles or any outside cause beyond the reasonable control of
the such party claiming the inability to perform whatsoever including, but not
limited to, governmental preemption in connection with a National Emergency, or
by reason of any rule, order or regulation of any department or subdivision of
any government agency or by reason of the conditions of supply and demand which
have been or are affected by war or other emergency. Similarly, Landlord shall
not be liable for any interference with any services supplied to Tenant by
others if such interference is caused by any of the reasons listed in this
Section. Nothing contained in this Section shall be deemed to impose any
obligation on either party not expressly imposed by other sections of this
Lease.


27. No Waivers. The failure of either party to insist, in any
one or more instances, upon a strict performance of any of the covenants of
this Lease, or to exercise any option herein contained, shall not be construed
as a waiver, or a relinquishment for the future, of such covenant or option,
but the same shall continue and remain in full force and effect. The receipt by
Landlord of rent, with knowledge of the breach of any covenant hereof, shall
not be deemed a waiver of such breach, and no waiver by either party of any
provision hereof shall be deemed to have been made unless expressed in writing
and signed by such party.


28. Access to Premises and Change in Services. Landlord shall
have the right, without abatement of rent, to enter the Premises at any
standard business hour to examine the same, or to make such repairs and
alterations as Landlord shall deem necessary for the safety and preservation of
the Building, and also to exhibit the Premises to be let; provided, however,
that except in the case of emergency, such entry shall only be after at least
twenty-four (24) hours advance written notice first given to Tenant and
Landlord shall use all reasonable efforts to limit such visits to a reasonable
number and duration. In the event of emergency, no advance written notice is
required to be given and Landlord shall have the right to enter during
non-standard business hours. Landlord acknowledges that Tenants Premises
contain highly sensitive proprietary and confidential information and other
property and agrees to abide by all reasonable measures imposed by Tenant to
protect the confidential and proprietary nature of such property and
information. If, during the last month of the Term, Tenant shall have removed
all or substantially all of Tenants property therefrom, Landlord may
immediately enter and alter, renovate and redecorate the Premises, without
elimination or abatement of rent, or incurring liability to Tenant for any
compensation, and such acts shall have no effect upon this Lease. Nothing
herein contained, however, shall be deemed or construed to impose upon Landlord
any obligation, responsibility or liability whatsoever, for the care,
supervision or repair, of the Building or any part thereof, other than as
herein elsewhere expressly provided. During the Renewal Term, (i) with respect
to the first floor or third floor of the Building, if Tenant does not lease the
entire floor, and (ii) with respect to the second floor of the Building, if
Tenant does not lease the Second Floor Key Area, Landlord shall also have the
right, without the same constituting an actual or constructive eviction and
without incurring any liability to Tenant therefor, to change the arrangement
and/or location of entrances or passageways, doors and doorways, and corridors,
stairs, toilets, elevators, or other public parts of the Building, and to
change the name by which the Building is commonly known and/or its mailing
address, provided that (i) in no event shall Landlords obligation to operate
the Building as a first class suburban office building be affected by a change
of the Buildings name and/or mailing address, and (ii) Tenant shall be given

their mutual objectives of constructing the Premises for Tenants occupancy as
soon as is reasonably practical, each party hereto has committed to specific

preparation and review as outlined in Section 34.2. Each party acknowledges and

due as liquidated damages within ten (10) days after the Commencement Date.
Subject to the provisions of Section 34.6 below, if Landlord is the

hereunder for such period as required to allow Tenant to recover the amount of
liquidated damages due to Tenant.

Any alterations, modifications or
deviations to the Approved Plans and Specifications requested by Tenant shall

Landlord pursuant to Tenants approved written change orders for any
individual change order which exceeds Ten Thousand Dollars ($10,000.00) shall
include all costs of labor and materials plus ten percent (10%) for overhead
and five percent (5%) for profit. At Tenants request, Landlord shall

deviate from the Approved Plans and Specifications in the field and prior to
the execution of a written change order and Landlord consents to such
deviation, Tenant or Tenants representative shall execute a written
authorization and indemnification in favor of Landlord. If such alterations,
modifications or deviations will extend the time to substantially complete the

34.3(k) accordingly.

constructing the Allowance Items (including a seven percent (7%) general
contracting fee to be paid to Landlord to cover Landlords indirect overhead
and profit and a separate charge for an on-site superintendent which shall be
invoiced separately at commercially reasonable rates to be approved in advance

Fifty-Eight Dollars ($1,198,658.00).

Events. As used in this Section 34, the term Force Majeure Events shall
refer to events which delay or prevent either party from constructing, making
any repairs, rebuilding or restoring, or furnishing any services or performing
any other covenant or duty, whether express herein or implied, to be performed
by such party due to strike, lockout, weather, embargo, war, governmental
orders or acts of God. If either party claims a Force Majeure Event has
occurred, it shall notify the other party in writing within twenty-five (25)
days after the occurrence of such event.


34.6 Adjustment of Liquidated
Damages.


If pursuant to Section 34.1
above, either party owes the other party liquidated damages for failing to
satisfy its obligations as described in Section 34.2 above and Landlord
substantially completes the Landlords Work in the Premises in a period which
is less than one hundred (100) days after the issuance of the building permit
for Landlords Work, then the amount owed by such party (or parties) as
liquidated damages shall be reduced by an amount equal to the time of the early
substantial completion of the Landlords Work.


34.7 Tenants Early Entry to
Premises Prior to Commencement Date. Tenant shall have the right to enter the
Premises prior to the Commencement Date for the purposes of installing Tenants
telecommunications and data equipment and such other improvements and
furnishings which are not included within Landlords Work, provided that (i)
Tenant shall submit to Landlord copies of all required permits and all

the form of the Approved Plans and Specifications, if there is a conflict
between the Approved Plans and Specifications and the terms of the Lease, the

and during any extension or renewal term peaceably and quietly enjoy the

the end of the Term of this Lease. If Tenant fails to vacate at such time there
shall be payable to Landlord an amount equal to one hundred fifty percent
(150%) of the monthly rent stated in paragraph 5 immediately prior to the
holding over period for each month or part of a month that Tenant holds over,
plus all other payments provided for herein, and the payment and acceptance of
such payments shall not constitute an extension or renewal of this Lease. In
event of any such holdover, Landlord shall also be entitled to all remedies
provided by law for the speedy eviction of tenants, and to the payment of all
attorneys fees and expenses incurred in connection therewith if Landlord
is the prevailing party in connection with a legal proceeding related thereto.

Landlords reasonable satisfaction that such Hazardous Material is
necessary or useful to Tenants business and will be used, kept and stored
in a manner that complies with all laws regulating any such Hazardous Material
so brought upon or used or kept in or about the Premises). If Tenant breaches

contamination of the Premises, the Building and/or the Property, or if
contamination of the Premises, the Building and/or the Property by Hazardous

damage resulting therefrom, then Tenant shall indemnify, defend and hold
Landlord and its Mortgagee(s) harmless from any and all claims, judgments,
damages, penalties, fines, costs, liabilities or losses (including, without
limitation, diminution in value of the Premises, the Building and/or the
Property, damages for the loss or restriction on use of rentable or usable
space or of any amenity of the Premises, the Building and/or the Property,

limitation, costs incurred in connection with any investigation of site
conditions or any cleanup, remedial, removal, or restoration work required by
any federal, state or local governmental agency or political subdivision

the Building. Without limiting the foregoing, if the presence of any Hazardous
Material on the Premises, the Building and/or the Property caused or permitted
by Tenant results in any contamination of the Premises, the Building and/or the
Property, Tenant shall promptly take all actions at its sole expense as are
necessary to return the Premises, the Building and/or the Property to the
condition existing prior to the introduction of any such Hazardous Material to
the Premises, the Building and/or the Property; provided that Landlords
approval of such actions shall first be obtained, which approval shall not be
unreasonably withheld so long as such actions would not potentially have any
material adverse long-term or short-term effect on the Premises or the Building.

|46. Americans With Disabilities Act.


Notwithstanding any other
provisions contained in this Lease and with the purpose of superseding any such
provisions herein that might be construed to the contrary, it is the intent of
the Landlord and Tenant that at all times while this Lease shall be in effect
that the following provisions shall be deemed their specific agreement as to
how the responsibility for compliance (and cost) with the Americans With
Disabilities Act and amendments to same (ADA), both as to the
Premises and the Property, shall be allocated between them, namely:


46.1 Landlord and Tenant agree to
cooperate together in the initial design, planning and preparation of
specifications for construction of the Premises so that same shall be in
compliance with the ADA.


46.2 Modifications, alterations
and/or other changes required to and within the Common Areas which are not
capital in nature shall be the responsibility of Landlord to perform and the
cost of same shall be considered a part of the Building Expenses and treated as
such.


46.3 Modifications, alterations
and/or other changes required to and within the Common Areas which are capital
in nature shall be the responsibility of Landlord and at its cost and expense.


46.4 Modifications, alterations
and/or other changes required to and within the Premises which are necessitated
by Tenants specific use of the Premises and not by office uses generally
(after the initial construction of same), whether capital in nature or
non-capital in nature, shall be the responsibility of Tenant and at its cost
and expense; unless said changes are structural in nature and result from the
original design of the Building, in which instance they shall be the
responsibility of Landlord and at its cost and expense.


Each party hereto shall indemnify
and hold harmless the other party from any and all liability, loss, cost or
expense arising as a result of a party not fulfilling its obligations as to
compliance with the ADA as set forth in this Section.


47. Exterior Building Signage. So long as Tenant occupies more
than fifty percent (50%) of the rentable square footage of the Building,
Tenant, at Tenants expense, shall have the exclusive right to install an
exterior sign on the Building. If Tenant occupies fifty percent (50%) or less
of the rentable square footage of the Building, Tenant, at Tenants expense,
shall have the non-exclusive right to install an exterior sign on the Building.
Any exterior sign installed by Tenant shall be subject to Landlords prior
approval, such approval not to be unreasonably withheld, with regard to the
size, location, aesthetics and method of installation of the signage. Landlord
shall use its reasonable efforts to coordinate the placement of Tenants
rooftop signage with other tenants in the Building so that any rooftop signs
are located at opposite ends of the Building, if and when applicable. Tenant,
at Tenants expense, shall maintain the signage. At the expiration or sooner
termination of the Term, Tenant shall remove the exterior signage on the
Building and restore the Buildings surface to that condition which existed
immediately prior to the installation of the signage.
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|48. Tenants Termination Rights. Provided that there is not an
Event of Default outstanding, Tenant shall have an one-time right to terminate
this Lease upon the expiration of the seventh (7th) rental year of the Initial
Term, by giving Landlord at least six (6) months advance written notice of its
intention to terminate this Lease, together with a payment in an amount equal
to the sum of (a) Two Hundred Ninety Thousand Four Hundred Forty-Four Dollars
and Sixty-Eight Cents ($290,444.66) (b) the unamortized leasing commissions
which will be based on the balance remaining after the 84th month of a ten (10)
year term, using a discount rate of nine percent (9%), and (c) the unamortized
portion of the Allowance as described in Section 34 above, which will be based
on the balance remaining after the 84th month of a ten (10) year term, using a
discount rate of nine percent (9%). If (i) there is an Event of Default
outstanding, or (ii) Tenant fails to exercise its termination rights and pay
the termination fee as described above, Tenants termination rights shall be
void and this Lease shall remain in full force and effect.


49. Leasing Incentive. As an incentive for entering into this
Lease, simultaneously with Tenants first monthly payment of Base Rent due
hereunder, (excluding the payment of Advance Rent) Landlord shall pay Tenant a
non-refundable incentive fee in the amount of Two Hundred Fifty Thousand
Dollars ($250,000.00).


50. Relocation Rights of Tenant. After the completion of the
fifth (5th) rental year, provided that there is not an Event of Default
outstanding, Tenant, at its option, shall have the right to relocate from the
Building to another property owned by Landlord or its successors or affiliates,
if Tenant requires premises with an area that is at least one hundred fifty
percent (150%) or more than the size of the Premises (as the same may have
increased) immediately prior to the requested relocation (the Relocation
Premises). The Relocation Premises shall be contained within a building in the
National Business Park which is planned for commencement of construction within
ninety (90) days after the date of Tenants Relocation Notice (as defined
below) under construction, or within a building that is to be built for
Tenants use by Landlord, its successors or assigns on a build-to-suit basis.


Tenant may notify Landlord in
writing of its interest in relocating from the Premises at anytime after the
expiration of the fifth (5th) rental year of the Initial Term (Tenants
Relocation Notice). Within fifteen (15) days after receipt of Tenants
Relocation Notice, Landlord shall notify Tenant in writing of the availability
of the Relocation Premises and of the economic terms of the lease relating to
the Relocation Premises which are acceptable to Landlord and Landlords lender
(Landlords Notice). The initial term of the lease for the Relocation
Premises shall be for at least ten (10) years and the amount of base rent shall
include any residual costs associated with the Initial Term under this Lease,
including, without limitation, unamortized tenant improvements and leasing
commissions. The form of the lease for the Relocation Premises shall be the
same form as this Lease except for such business terms which have been modified
by mutual agreement of Tenant and Landlord, including, without limitation, the
size of the Premises and the Base Rent due for the Relocation Premises.


Tenant shall notify Landlord
within fifteen (15) days after receipt of Landlords Notice whether it accepts,
rejects or wishes to modify any terms of the Landlords Notice. Landlord and
Tenant shall then have successive periods of five (5) days each to negotiate
and or respond to Landlords Notice, as modified. After Landlord and Tenant
agree to the terms of Landlords Notice, as modified, Landlord and Tenant shall
enter into a new lease for the Relocation Premises, which by its terms will
terminate this Lease. If (i) Tenant does not respond to Landlords Notice
within the first fifteen (15) day period, (ii) Tenant does not respond to
Landlords Notice, as modified, during the succeeding five (5) day periods,
(iii) Landlord and Tenant do not agree to the final terms of the lease of the
Relocation Premises within sixty (60) days after the date of Tenants
Relocation Notice, or (iv) Landlord and Tenant have not entered into a lease
for the Relocation Premises within thirty (30) days after agreeing to the terms
of the rental of the Relocation Premises, then Tenants right to relocate from
the Premises shall be void and of no further force or effect. This relocation
right may not be separately assigned or transferred by Tenant.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|51. Leases with Other Tenants. During the Initial Term and the
Renewal Term (provided that Tenant exercises its renewal option for the all of
the Premises and not just a part thereof), Landlord agrees that all leases with
tenants of the Building (Other Tenants) shall contain relocation clauses, and
Tenant agrees that Tenant shall reimburse Landlord for all expenses incurred by
Landlord to relocate such Other Tenants if the relocation is made to
accommodate Tenants expansion rights as contained herein.


52. Tenants Rights Upon Landlords Default. If Landlord fails
to perform any of its obligations hereunder, Tenant shall notify Landlord in
writing and Landlord shall cure or commence to cure such failure within fifteen
(15) days after the date of the written notice and diligently prosecute the
cure to completion; provided, that in an emergency situation, Tenant shall use
its reasonable efforts to notify Landlord in advance, but shall have the right
to remedy the situation creating the emergency. If Landlord fails to complete
the cure as required, Tenant shall have the right, but not the obligation, to
complete the cure on behalf of Landlord. In such event, Landlord shall
reimburse Tenant for the actual costs incurred by Tenant within thirty (30)
days after the date of Tenants invoice to Landlord, which shall include
reasonable supporting evidence, together with interest at the rate of thirteen
percent (13%) per annum, commencing on the date of Tenants invoice. The
provisions of this Section shall be in addition to any other rights and
remedies afforded to Tenant at law or in equity.


53. Right of First Refusal. Landlord agrees that during the
Term of this Lease, Tenant shall have a continuing right of first refusal in
connection with a lease from Landlord of all or any portion of the rentable
area in the Building which is not contained within the Premises (the Option
Space),
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|whether for the initial leasing of the area or for subsequent
releasing, subject to the vacation of the Option Space by the other tenant in
the case of a releasing and subject to the limitations set forth in this
Section. Commencing on the date hereof, upon receipt of an offer from a third
party to lease all or a portion of the Option Space, Landlord shall notify
Tenant in writing of the existence of such offer (Landlords Offer Notice)
and the then Prevailing Market Rate (as defined in Section 2.3) for the Option
Space. Tenant shall exercise the foregoing right of first refusal by delivering
written notice of its intention to lease all or a portion of the Option Space
within ten (10) days after Tenants receipt of Landlords Offer Notice.
Tenants election notice shall specify all or which portion of the Option Space
for which Tenant is exercising such right of first refusal.


53.1 Terms of Rental for Option
Space. If Tenant exercises its rights in a timely fashion under Section 53
above, (i) the length of the term of the Lease for the Option Space (or part
thereof) shall be for at least three (3) years (including the right to any
remaining renewal options contained under this Lease), (ii) any additional rent
due in connection with the lease of the Option Space (or a part thereof) and
all other terms relating to the rental of the Option Space (or a part thereof)
shall be the same as for the Premises, (iii) the Base Rent shall be equal to
the Prevailing Market Rent as set forth in Landlords Offer Notice and (iv) all
other terms relating to the rental of the Option Space (or a part thereof)
shall be the same as for the Premises.


53.2 Entry into Lease Amendment.
Within thirty (30) days after the date of the Landlords Offer Notice, as the
case may be, Landlord and Tenant shall enter into a written amendment to this
Lease which adds the Option Space (or a part thereof) to the definition of the
Premises and sets forth the Base Rent and such other matters which are at
variance with the terms and conditions of this Lease, with rent commencing on
the Option Space upon occupancy by Tenant.


53.3 Miscellaneous Matters. If
(i) Tenant is then in default under the terms of this Lease at the time of
exercising its rights under this Section 53, (ii) Tenant fails to deliver the
requisite notice to Landlord exercising such right within the ten (10) day
periods specified above, (iii) Tenant fails to execute an amendment to this
Lease for the Option Space (or a part thereof) within the thirty (30) day
period, or (iv) Tenant declines to exercise its rights as provided above as to
all or any portion of the Option Space, then Landlord shall be free to proceed
to lease that portion of the Option Space specified in (i) Landlords Option
Notice to third parties (ii) Landlords Offer Notice to such third party. The
rights of first offer and rights of first refusal shall not be severed from
this Lease, or separately sold, assigned or transferred, but may only be
assigned or transferred as a part of this Lease.


IN WITNESS WHEREOF, Landlord and
Tenant have respectively affixed their hands and seals to this Lease as of the
day and year first above written.
