Lease incurred after the Commencement Date and not charges which accrued prior to the Commencement
Date. (c) All amounts payable by Subtenant to Sublandlord pursuant to this Sublease, including,
without limitation, Base Rent and Additional Rent, shall be deemed and constitute rent and, in the

related thereto if required by Prime Landlord. 7. Subordination to and Incorporation of Terms of Prime Lease. This Sublease is in
all respects subject to the terms and conditions of the Prime Lease and to the matters to which the
Prime Lease is or shall be subordinate. Except as otherwise expressly provided in this Sublease,

extent that the terms and conditions do not relate to the Premises or are inapplicable to,
inconsistent with, or modified or eliminated by, the terms of this Sublease, and except for those

Lease as specified in the preceding sentence, or a breach of this Sublease, Subtenant shall not
make any claim against Sublandlord. 4

dealt with any broker in connection with this Sublease other than Scheer Partners (the Broker),
which represents the Sublandlord, and The Staubach Company-Northeast, Inc. (the Co-Broker), which
represents the Subtenant. Subtenant shall indemnify Sublandlord against, and hold Sublandlord
harmless from any claim on, or liability to, any broker or any party with whom Subtenant shall have
dealt with in connection with this Sublease transaction, other than Broker. Sublandlord shall have
no obligation for commissions related to the Co-Broker, and each party agrees to indemnify the

willful misconduct of Sublandlord, (ii) any work or thing whatsoever done, or any condition
created, by Subtenant in, on or about the Premises or the Building, or (iii) any act or omission of
Subtenant, its agents, contractors, servants, employees, invitees or licensees. 13. Rights Reserved to Sublandlord. Any expansion, renewal, first refusal, or other

##### 



obligation to exercise any such rights or options) and may not be exercised by Subtenant.
Sublandlord agrees that, provided Subtenant is not in default at the time any notice of the right
of renewal is to be given, Sublandlord will not exercise any right of renewal of the Prime Lease.
Both Sublandlord and Subtenant shall have whatever right exists in the Prime Lease for Sublandlord
to contest property taxes, but without any obligation to exercise any such right. Subtenant shall
have whatever rights to signage which Prime Landlord approves for the benefit of Subtenant. 14. Termination of the Prime Lease. If for any reason the term of the Prime Lease is
terminated prior to the Expiration Date of this Sublease, this Sublease shall thereupon terminate,
and Sublandlord shall not be liable to Subtenant by reason thereof unless said termination shall
have been effected because of the default of or voluntary surrender by Sublandlord under the Prime
Lease, or unless Sublandlord has failed to abide by Sublandlords obligations pursuant to Section
10(c) above. 15. Modification of Prime Lease. For the purposes hereof, the terms of the Prime Lease

Lease. 16. Consents. Sublandlords refusal to consent to or approve any matter, whenever
Sublandlords consent or approval is required under this Sublease or under the Prime Lease, as

Landlord has refused or failed to give its consent or approval to such matter after due
consideration. 17. Condition of the Premises: Subtenants Changes. (a) Subtenant represents that it has made a thorough examination of the Premises and it is

any improvements therein or of the Building. (b) Subtenant may make whatever changes to the Premises Prime Landlord allows, including,
without limitation, structural or non-structural changes, without the prior written consent of

Sublandlord-owned Personal Property, including the Office Furniture (as hereinafter defined) until

or extended coverage insurance policy obtained by it and covering the Premises or the personal
property, fixtures and equipment located therein or thereon, pursuant to which the respective
insurance companies waive subrogation or permit the insured, prior to any loss, to agree with a

of this Sublease, including without limitation the surrender of possession of the Premises to
Sublandlord as herein provided. It is agreed that in the event Subtenant defaults in respect of
any of the monetary terms, provisions and conditions of this Sublease beyond any applicable cure
periods, including, but not limited to, the payment of Base Rent and Additional Rent, Sublandlord
may draw upon the Letter of Credit, in accordance with its terms, to the extent required for the
payment of any Base Rent and Additional Rent or any other sum as to which Subtenant is in default
or for any sum which Sublandlord may expend or may be required to expend by reason of Subtenants
default in respect of any of the terms, covenants and conditions of this Sublease, including but
not limited to, any damages or deficiency in the reletting of the Premises, whether such damages or
deficiency accrue or accrues before or after summary proceedings or other reentry by Sublandlord.
The draw upon the Letter of Credit, or any portion thereof by Sublandlord shall not prevent
Sublandlord from exercising any other right or remedy provided by this Sublease or by law and shall
not operate as a limitation on any recovery to which Sublandlord may otherwise be entitled. (b) Such Letter of Credit shall be subject to the following terms and conditions. Such Letter
of Credit shall: (a) be in form and substance satisfactory to Sublandlord in its reasonable
discretion; (b) state on its face that multiple draws are permitted; (c) be issued by a commercial
bank acceptable to Sublandlord from time to time and located in the metropolitan

no charge by Sublandlord, which transfer/assignment shall be conditioned only upon the execution of
a reasonable and customary written document in connection therewith, whether or not the original
account party of the Letter of Credit continues to be the tenant under this Sublease by virtue of a
change in name or structure, merger, assignment, transfer or otherwise; (e) be payable at sight
upon presentment to a local branch of the issuer of a simple sight draft or certificate stating
only that Subtenant is in default under this Sublease and the amount that Sublandlord is owed in
connection therewith; (f) be of a term not less than one year, and shall on its face state that the
same shall be renewed automatically, without the need for any further written notice or amendment,
for successive minimum one-year periods, unless the bank notifies Sublandlord in writing that such
bank has elected not to renew the Letter of Credit at least sixty (60) days prior to the expiration
date thereof (which will entitle Sublandlord to draw on the Letter of Credit not more than fifteen
(15) days before the scheduled expiration date if a replacement Letter of Credit (or substitute
acceptable to Sublandlord in its sole and absolute discretion) has not been established and
delivered to Sublandlord; provided, however, that the Letter of Credit shall terminate upon the
entry of an order authorizing the Sublandlord to reject this Sublease in any proceeding initiated
under Title 11 of the United States Code; and (g) at least thirty (30) days prior to the
then-current expiration date of such Letter of Credit, either (1) renewed (or automatically and
unconditionally extended) from time to time through the ninetieth (90th) day after the expiration
of the Term, or (2) replaced with cash in the stated amount. Notwithstanding anything in this
Sublease to the contrary, any cure or grace periods set forth in this Sublease for a default shall
not apply to any of the foregoing requirements of the Letter of Credit, and, specifically, if any
of the aforesaid requirements are not complied with timely, time being of the essence, then an
immediate Event of Default shall occur and Sublandlord shall have the right to immediately draw
upon the Letter of Credit. 10

If Subtenant shall fully and faithfully comply with all of the terms, provisions, covenants
and conditions of this Sublease, the Letter of Credit shall be canceled/terminated within thirty
(30) days after the expiration date (or sooner termination) of the Sublease and delivery of the
entire possession of the Premises to Sublandlord. Notwithstanding anything to the contrary contained herein, in the event Sublandlord draws on
any part or all of the Letter of Credit, Subtenant shall, within ten (10) days of such drawing,
either restore the Letter of Credit to its original amount, deliver to Sublandlord a substitute

 In addition to said Basic Monthly Rental, Tenant shall pay to Landlord, at the times and in the
manners hereinafter indicated, the additional items and amounts specified in Section 4 hereof for
utility charges and Operating Expenses, and in Section 8 hereof for Impositions and Insurance
Premiums, plus such other sums as are required to be paid by Tenant pursuant to the terms of this
Lease. All rentals and other sums payable by Tenant hereunder shall be paid to Landlord at 9108
Gaither Road, Gaithersburg, Maryland 20877, or to such other party and address as Landlord may
from time to time designate to Tenant in writing. Upon execution of this Lease, Tenant will pay to
Landlord the sum of FIFTY-NINE THOUSAND SIX HUNDRED EIGHTY-SIX and 00/100 DOLLARS ($59,686.00)
covering Basic Monthly Rental for the 1st monthof the Stated Term. Regarding all of Tenants
covenants, obligations and duties to make Rental and other payments and to perform its other
agreements contained in this Lease, time is agreed to be of the essence. (D) SECURITY DEPOSIT. The Tenant further agrees to deliver to Landlord, on the
Commencement Date of the Initial Term hereof (as established pursuant to Paragraph 1(B) above),
either (i) an irrevocable, unconditional commercial bank letter of credit, payable upon sight in
the amount of SEVEN HUNDRED SIXTEEN THOUSAND TWO HUNDRED THIRTY-TWO and 00/100 DOLLARS
($716,232.00)(the Letter of Credit) in substantially the form attached hereto as Exhibit
D and initialed by the parties, or such other form reasonably acceptable to Landlord, issued
by a federally-insured national bank having offices in the Metropolitan Area of Washington, D.C.
(Landlord will accept a qualified out-of-town bank that makes arrangements which are acceptable to
Landlord with a qualified corresponding bank in the Metropolitan Area of Washington, D.C.), or (ii)
a certificate of deposit issued by a commercial bank in the amount of SEVEN HUNDRED SIXTEEN
THOUSAND TWO HUNDRED THIRTY-TWO and 00/100 DOLLARS ($716,232.00)(the Certificate of 2

##### 



Deposit). The Letter of Credit or the Certificate of Deposit are hereinafter referred to as
the Security Deposit. The Security Deposit shall be reduced by ONE HUNDRED FORTY-THREE THOUSAND
TWO HUNDRED FORTY-SIX AND 40/100 DOLLARS ($143,246.40) for each twelve (12) month period during the
first five (5) years of the Initial Term that Tenant has not been in an Event of Default. However,
if an Event of Default of Tenant occurs at any time after the first five (5) years of the Initial
Term, Landlord, at its option and sole discretion, shall have the right to require Tenant to
furnish to Landlord a Security Deposit in the amount of the then current Basic Monthly Rental,
which Security Deposit shall be retained by Landlord for the balance of the Stated Term of this
Lease. The Security Deposit shall be for an initial period of at least one (1) year from the
Commencement Date of the Initial Term hereof; and Tenant will deliver to Landlord at least thirty
(30) days before expiration of the Security Deposit a new Security Deposit or renewal of the
original one, renewing the Security Deposit in the sum required above for successive periods of at
least one (1) year each (or such shorter period which will be identical to the then remaining term
of this Lease plus an additional thirty (30) days thereafter), so that, at all times that Tenant is
required to maintain the Security Deposit, Landlord shall have in its possession a good Security
Deposit in the amount specified above. In the event Tenant delivers a Certificate of Deposit in
lieu of a Letter of Credit, the Certificate of Deposit shall be in the name of the Landlord (but
reported for income tax purposes as Tenants income on Tenants tax identification number with
interest payable at least annually to Tenant). In the event Tenant delivers a Letter of Credit as
the Security Deposit, the Letter of Credit shall include provision for assignment thereof to any
mortgagee with a collateral assignment of this Lease. Failure of Tenant to timely comply with any
requirements of this Subparagraph 1(D) shall constitute an Event of Default of Tenant under this
Lease. If an Event of Default of Tenant occurs under this Lease (as defined in Section 12 hereof),
said Security Deposit may, at Landlords option and discretion (and without waiving any other
rights or remedies of Landlord), be converted to the amount of cash necessary to cure the Event of
Default. Such application shall, however, in no way affect Landlords rights to recover from
Tenant further damages or loss of Rent which may accrue by reason of Tenants defaults under this
Lease. Provided an Event of Default of Tenant does not then exist under this Lease, the balance
(if any) of said Security Deposit not applied to curing the Tenants defaults shall be refunded and
released to Tenant (without interest) within thirty (30) days after the expiration of this Lease,
provided that Tenant has surrendered to Landlord possession of the Demised Premises in accordance
with the terms of this Lease. The Security Deposit shall not be construed as advance payment of
Rent hereunder, but shall be considered only as representing a fund made available to Landlord to
secure the prompt and faithful performance by Tenant of its covenants under this Lease. Tenant
shall, within ten (10) days after demand by Landlord, restore said Security Deposit to the full
amount specified above and/or as required during the term of this Lease, in the event any portion
or all thereof is applied by Landlord to cure an Event of Default of Tenant hereunder. (E) HOLDOVER. If Tenant fails to quit and vacate the Demised Premises at the
expiration of the Initial Term (or at the expiration of the final duly exercised Renewal Term
hereof, if any, as the case may be), and if Landlord accepts payment of rental from Tenant
thereafter and thus indicates that Landlord does not require the Tenants immediate surrender of
possession of the Demised Premises at such expiration date, then in such event any such holding
over of possession of the Demised Premises by Tenant shall be deemed to create only a tenancy from
month-to-month, beginning for same on the day immediately following the expiration of 3




---



##### 



the then expired term hereof, such monthly hold-over tenancy to be upon all of the terms,
covenants and conditions contained in this Lease, except that either party by giving to the other
at least sixty (60) days prior written notice may terminate such monthly holdover tenancy (except
that Tenant shall not be entitled to such notice of termination, and hereby waives same, in the
event that Tenant is in an Event of Default under this Lease in any respect beyond any applicable
grace periods). Notwithstanding the foregoing provisions of this paragraph, if Landlord desires
possession of the Demised Premises at the end of the term hereof, then Landlord may so notify
Tenant at any time prior to accepting monthly holdover rent, in which event Tenant covenants and
agrees to surrender to Landlord possession of the Demised Premises at the end of the term hereof
free of subleases and occupants, and if Tenant fails to do so it shall be deemed an Event of
Default under this Lease and Tenant shall be liable to Landlord for all reasonable, actual losses,
costs, damages and expenses Landlord incurs from Tenants failure to vacate the Demised Premises as
prescribed above. If the provisions of the preceding sentence become applicable, Tenant shall pay
Landlord use and occupancy payments for each month or portion thereof Tenant wrongfully holds over
possession of the Demised Premises in whole or part, in an amount equal to one hundred fifty
percent (150%)of the Basic Monthly Rental payable in the last month of the term hereof (in
addition to Landlord being entitled to exercise all available legal and equitable remedies).
Landlord hereby notifies Tenant that Landlord desires and intends that Tenant remove from, quit and
vacate the Demised Premises at the expiration of the term of this Lease, and Tenant hereby agrees
to do so and hereby irrevocably waives any and all rights to notice from Landlord of such intent as
provided in Title 8, Section 8-402(b) of the Real Property Volume of the Annotated Code of
Maryland, as amended, or under any similar statute now or hereafter enacted. (F) ADDITIONAL RENT. Whenever it is provided by the terms of this Lease that Tenant
is required to make any payment to Landlord other than a payment of Basic Monthly Rental (such as
the additional items and amounts specified in Section 4 hereof for utility charges and Operating
Expenses and in Section 8 hereof for Impositions and Insurance Premiums, or amounts to reimburse
Landlord for legal costs and attorneys fees, or for any other such sums), such payment shall be
deemed to be a payment of Additional Rent. Unless otherwise expressly specified herein,
Additional Rent shall be paid by Tenant by the later of (i) the next installment of Basic Monthly
Rental thereafter falling due or (ii) within thirty (30) days after request therefor. For all
purposes of this Lease, the term Rent shall be deemed to be a reference to both Basic Monthly
Rental and Additional Rent. Landlord shall have the same remedies for default in the payment of
Additional Rent as are available to Landlord in the case of default in the payment of Basic Annual
Rental or Basic Monthly Rental. (G) LATE CHARGE. In the event Tenant does not pay any installment of Rent or
Additional Rent or any other sums when and as the same become due and payable under this Lease, and
if such payment is not made within ten (10) daysafter the due date thereof, Tenant shall pay to
Landlord, as Additional Rent hereunder, in addition to the unpaid amount, a Late Charge equal to
five percent (5%) of the unpaid amount to compensate Landlord for the additional expense resulting
from Tenants failure to make payment in accordance with the terms of the Lease. If Tenant fails
to make any payment due under this Lease within the aforesaid ten (10) day grace period more than
twice in any Lease Year, then the Late Charge shall increase 4




---



##### 



thereafter for the balance of that Lease Year, for all late payments, to be ten percent (10%)
of the unpaid amount, and such increased Late Charge shall be payable as aforesaid.  2.
    TENDER OF POSSESSION; LANDLORDS WORK; BUILDING SHELL; TENANT IMPROVEMENT
ALLOWANCE; TENANTS WORK. (A) TENDER OF POSSESSION. If Landlord shall be unable to deliver to Tenant
possession of the Demised Premises (in the condition as called for in Paragraph 2(B) hereof) on the
Commencement Date of the Stated Term hereof by reason of the fact that the Demised Premises are
located in the Building which is to be constructed and the Building has not been sufficiently
completed to make the Demised Premises ready for delivery to Tenant as called for in Paragraph 2(B)
hereof, or if the Landlord is unable to give Tenant possession of the Demised Premises on the
Commencement Date of the Stated Term hereof by reason of the holding over or retention of
possession by any tenant or occupant, or for any other reason, Landlord shall not be subject to any
liability for the failure to give possession on said date. Under such circumstances, the Rent
herein reserved and covenanted to be paid by Tenant shall abate and not commence to be due and
payable until Landlord delivers to Tenant possession of the Demised Premises as called for in
Paragraph 2(B) hereof; and no such failure of Landlord to deliver possession on the Commencement
Date of the Stated Term shall affect the validity of this Lease or otherwise affect the obligations
of Tenant hereunder, except that in such event the date of expiration of the Stated Term hereof
shall be extended by the same number of days that shall elapse from the Commencement Date specified
in Paragraph 1(B) until the end of the calendar month in which possession of the Demised Premises
is delivered to Tenant as called for in Paragraph 2(B), such delivery date to be established by
written notice from Landlord to Tenant. If permission is given by Landlord to Tenant to enter into
the possession of all or a portion of the Demised Premises, or to occupy space other than the
Demised Premises, prior to the Commencement Date of this Lease, Tenant covenants and agrees that
such occupancy shall be deemed to be under all the terms, covenants, conditions and provisions of
this Lease except as may be otherwise agreed in writing by Landlord and Tenant. If Landlord is
prevented from or delayed in delivering possession of the Demised Premises to Tenant in the
condition called for in Paragraph 2(B) hereunder due to any Tenant Delays (as hereinafter defined),
then the Commencement Date of the Lease shall be the date, as reasonably determined by Landlord,
that the Demised Premises could have been delivered to Tenant absent the Tenant Delays. If Tenant
is able to obtain a temporary Certificate of Use & Occupancy from the Montgomery County Department
of Permitting Services that allows Tenant to occupy a portion of the office space in the Premises
prior to the Rent Commencement Date, Landlord agrees that during such partial occupancy, no Basic
Annual Rental shall be due and payable by Tenant. However, Tenant shall be responsible for its Pro
Rata Share of the Operating Expenses, Impositions and Insurance Premiums (all as defined below)
incurred by Landlord during the time of such partial occupancy. (B) LANDLORDS WORK. The Tenant agrees to accept possession of the Demised Premises,
when delivered by Landlord as provided in this Subparagraph 2(B), for the term herein created, upon
the agreements and covenants herein expressed, and does hereby covenant and agree that Tenant shall pay unto Landlord the rents, taxes, insurance, expenses,
repairs and other costs and charges called for or reserved in this Lease, at the time or times the
same are due and payable as herein specified. The Demised Premises shall be delivered by 5

Landlord
to Tenant, and shall be accepted by Tenant, with the Landlords Work (as described on Exhibit
C attached hereto, initialed by the parties and made a part hereof) Substantially Complete(
as defined herein), as established by the notice from Landlord to Tenant mentioned in Paragraph
2(A) above. Such notice from Landlord shall indicate the commencement and expiration dates of the
Stated Term of this Lease. (C) BUILDING SHELL. Attached hereto as Exhibit C and made a part hereof is
an outline specification of the Building Shell to be constructed by Landlord at Landlords sole
cost and expense. The Building Shell shall be constructed from contract plans and specifications
prepared by Landlords professional design consultants, a list of which is included in Exhibit
C. (D) TENANT IMPROVEMENT ALLOWANCE. Landlord shall grant Tenant a one-time allowance
of ONE MILLION THREE HUNDRED TWENTY-SIX THOUSAND THREE HUNDRED FIFTY and 00/100 DOLLARS
($1,326,350.00)(the TI Allowance) to be used by Tenant to construct leasehold improvements in
the Demised Premises (Tenants Work) as detailed in the plans and specifications to be prepared
by Gaudreau, Inc. (TI Architect). The TI Allowance may be used for any improvements classified
under generally accepted accounting principles as leasehold improvements (or real property), but
not for improvements classified as furniture, fixtures and equipment (or personal property). The
TI Allowance may be used for leasehold improvements such as roof mounted HVAC systems, ductwork and
equipment, clean water systems, plumbing, restroom fixtures, electric water coolers, built-in
millwork, exhaust ducts, flues and fans, electrical circuitry, lighting and power distribution
systems, generator pads and enclosures, floor coverings, walls, doors and door hardware, ceilings
and gas, vacuum, compressed air, and other similar central systems. The TI Allowance may not be
used for things such as floor mounted cooling units (and associated condensor units), autoclaves,
glass washing equipment, fume hoods, biosafety cabinets, chemical storage cabinets, chillers for
scientific equipment, generators, PBX control equipment, telephone and internet systems, security
systems, data storage devices, datacom handling equipment, and fuel tanks. The above lists include
items listed by way of example and not limitation. The TI Allowance may include the cost of
preparing all plans and specifications required to perform Tenants Work. Tenant shall be allowed
to select a general contractor to perform the Tenants Work, provided said general contractor shall
be properly licensed, bonded and of a reputation reasonably acceptable to Landlord. An affiliate
of Landlord, Minkoff Development Corporation (MDC), shall act as Landlords construction manager
to review plans and oversee construction of the Tenants Work by the general contractor. MDC shall
receive a fee equal to one percent (1%) of the total cost of the Tenants Work, which fee shall
also be a part of the TI Allowance. If the entire TI Allowance is not used to construct the
Tenants Work, Landlord (at its own discretion and as notified to Tenant in writing within sixty
(60) days of the Rent Commencement Date) will apply the unused portion of the TI Allowance (the
Allowance Credit) either to (1) provide Tenant with a credit against the next due installment(s)
of Rent due under the Lease, or (2) reduce the Basic Monthly Rental payments specified in Paragraph
1(C) hereunder by the Amortized Cost (as defined below) of the Allowance Credit. If the TI
Allowance is not sufficient to construct the Tenants Work, Tenant shall provide whatever remaining funds are
necessary to complete the Tenants Work. As used herein, the phrase Amortized Cost shall refer
to the sum calculated by amortizing the Allowance Credit over the Initial Term of the Lease 6




---



##### 



at ten
percent (10%) per annum. By way of example, for each one dollar ($1.00) per square foot of
Allowance Credit, the Basic Monthly Rental changes by 1.322 cents ($0.01322) per square foot per
month. The provisions of this Paragraph 2(D) shall not apply during any renewal term or holdover
term. If this Lease is terminated due to an Event of Default or due to any Events of Bankruptcy,
all allowances granted to Tenant under this Paragraph 2(D) shall form part of the damages
recoverable by Landlord from Tenant as provided in Paragraph 12 (G); provided, however, that under
no circumstances shall Landlord be allowed to recover any damages for such allowances that are
included in any other damages awarded to and collected by Landlord pursuant to the provisions of
this Lease. (E) TENANTS WORK. Tenant shall have the right to submit plans for the Tenants Work
in stages for portions of the Demised Premises. Tenant shall cause the TI Architect to prepare and
deliver to Landlord for Landlords or MDCs review preliminary plans (architectural, mechanical,
electrical, plumbing and structural, if necessary) and specifications for the proposed leasehold
improvements (the Preliminary Plans). Landlord shall have ten (10) business days after its
receipt thereof (or such additional time as may reasonably be necessary) to review the Preliminary
Plans, request any changes it deems reasonably appropriate, and indicate on the Preliminary Plans
which portions of the leasehold improvements are to be removed by Tenant prior to the expiration or
termination of the Lease. The TI Architect shall modify the Preliminary Plans to accommodate
Landlords changes, and resubmit the revised plans (the Revised Preliminary Plans) to Landlord
for approval. If Tenant or the TI Architect elect not to make said changes to the Preliminary
Plans, then Landlord shall have the right to require Tenant to perform corresponding restoration
work to effect said changes prior to the expiration or termination of the Lease. Upon receipt of
Landlords approval of the Revised Preliminary Plans, the TI Architect shall prepare a complete set
of construction drawings and specifications for the construction of the proposed leasehold
improvements (the Working Drawings). The Working Drawings shall be in sufficient detail for (i)
Tenants general contractor to obtain bids from all trades for and to perform the work described on
the Working Drawings; (ii) Tenants general contractor to secure building permits from the
requisite governmental authorities having jurisdiction over same; and (iii) Landlord or MDC to
indicate the portion of Tenants Work, if any, which Tenant is to remove by expiration or
termination of the Lease. The Working Drawings shall conform to and be consistent with the Revised
Preliminary Plans and comply with all applicable Laws and Insurance Requirements, as those terms
are defined in the Lease. The Working Drawings shall be submitted to MDC for review and approval,
which approval (or a request for changes to be made) shall be given within fifteen (15) days after
receipt thereof. Within five (5) business days after MDCs approval of the Working Drawings, as
modified by any revisions requested by MDC, Landlord and Tenant shall initial same to confirm their
mutual approval thereof (the Approved Working Drawings). The Approved Working Drawings will
indicate which portions of the Tenants Work, if any, will have to be removed by Tenant prior to
the expiration or termination of the Lease, and Tenant will timely comply with such requirement and
repair any damage to the Land or the Building caused thereby at its own expense. Tenant will have
no obligation to remove any other portion of the Tenants Work.  3.

MODIFICATIONS; SURRENDER OF POSSESSION; MECHANICS LIENS. (A) USE OF PREMISES. Tenant covenants and agrees to use the Demised Premises only as
and for the conduct and operation of an OFFICE, STORAGE AND LABORATORY FACILITY FOR TENANTS
BUSINESS (Tenants Use), such use to be conducted by Tenant at its own expense in compliance with
all applicable Laws and Insurance Requirements as defined in Section 10 and all provisions of this
Lease, and for no other purpose without the express written consent of the Landlord, which consent
shall be in Landlords exclusive discretion. The current I-3 zoning permits such Tenants Use. (B) TENANT RESPONSIBILITIES. Tenant agrees at its own expense to maintain the
Demised Premises in a clean, neat and orderly manner and to keep the Demised Premises free of
rodents and insects and to furnish regular pest inspection services and exterminating services, if
required. Tenant shall be solely responsible, at its own cost and expense, and will provide when
and as necessary, all services typically required within the Demised Premises (except as may be
specified in Section 4 hereof) including but not limited to janitorial service, restroom and break
room supplies, interior window cleaning, light bulb and ballast replacement, flooring maintenance,
and any other services customarily required by the Tenants use of the Demised Premises. In no
event shall Landlord be obligated to provide, pay for or contribute to the cost of any of these
services in or for the Demised Premises. Tenant further agrees that it will not, under any
circumstances, display or permit to accumulate for an extended period of time any merchandise,
boxes or other articles on the driveways, parking areas, streets or sidewalks in front of or
adjacent to the Demised Premises. Tenant shall not maintain a nuisance in or about the Demised
Premises, and will conduct its business at the Demised Premises, and have its Permittees conduct
themselves, in such a manner so as not to interfere with nor unreasonably disturb other tenants
quiet possession of, or conduct of normal business at, their leased premises. Tenant shall not
burn any trash in or outside the Demised Premises, nor install an incinerator or trash destructor
in or outside of said Demised Premises. (C) REPAIRS AND MAINTENANCE. Except for the specific repairs, maintenance and
replacements to be made by Landlord pursuant to this Lease, in all other respects the Tenant will,
during the full term of this Lease, at its own expense, promptly make all repairs and perform all
acts of maintenance necessary to keep the Demised Premises and all improvements, equipment and
utility lines therein and all other elements thereof in good condition and repair, including also
without limitation all maintenance, repairs and replacements, excepting only for repairs to the
structure and to any utility lines located outside of the Structure (as defined below) of the
Demised Premises (such lines hereinafter called Exterior Utility Lines); unless such repairs of
the Structure or of the Exterior Utility Lines are necessitated by any acts, omissions or
negligence of Tenant or its assignees or subtenants or its or their agents, employees, contractors,
invitees, licensees, customers or subtenants (Permittees), in any of which events Tenant at its own expense (but subject to the recovery
of any applicable insurance proceeds) shall make such repairs and replacements of the Structure and
Exterior Utility Lines promptly when necessary (or, if requested by Landlord, Tenant will reimburse
Landlord for the costs of such repairs and replacements within thirty (30) days of demand
therefor). Said repairs to the Structure and Exterior Utility Lines shall be made by 8

##### 



Landlord
(except as otherwise provided in the preceding sentence) as promptly as commercially practicable
after receipt of written notice from Tenant to Landlord of the necessity therefor. Tenant shall
give Landlord prompt notice of any fire, accident, defects, damage or injury occurring at, in or to
the Demised Premises and of any death, damage or serious injury to persons therein, but nothing
herein contained shall be construed to require Landlord to make any repairs to said Demised
Premises or to provide compensation for any such damage or injury, except as otherwise expressly
herein provided. For purposes of this Paragraph 3(C) and of all other provisions of this Lease,
the term Structure shall refer to the foundations, structural frame, exterior walls and glazing,
ground floor slab and roof of the Building, and the term Exterior Utility Lines shall refer to
all electrical, plumbing, and sewage systems and lines (including but not limited to gas, telephone
and fiber optic) located outside of the Structure of the Demised Premises. Tenant, at its own
expense, will make all repairs, maintenance and replacements promptly when and as necessary for the
heating, ventilating and air-conditioning systems and equipment which serve only the Demised
Premises (HVAC). Tenant at its own expense will keep in force throughout the term of this Lease
a contract for maintenance of the HVAC serving the Demised Premises with a competent, licensed
mechanical contractor reasonably acceptable to Landlord. Tenant shall cause the HVAC to be
maintained in good condition by such mechanical contractor. (D) INTERIOR ALTERATIONS. Except for ordinary office decorations (that are not
leasehold improvements), any partitioning, painting, installation, removal or alteration of utility
lines, flooring, paneling, mechanical equipment (heating, ventilating or air conditioning),
plumbing, electrical, gas, water, sewer, interior, exterior, roof or other alterations, changes or
additions to the Demised Premises which Tenant may desire to perform or make (the Alterations)
shall be subject to the following conditions, namely: (i) no such Alterations shall be done
without Landlords express prior written consent in each instance; (ii) complete plans and
specifications and a cost estimate for any such Alterations (if reasonably required due to the
nature of the work contemplated) shall be submitted to Landlord and Landlords written approval
thereof obtained prior to commencement of such Alterations (which Alterations shall be done in
strict compliance with such plans and specifications if and as so approved); (iii) the Alterations
are to be done in compliance with all applicable governmental laws, codes, orders and regulations,
without any damage to the Demised Premises or the Building of which same are a part or to any
property of Landlord or other tenants, free of liens and claims and all at Tenants sole cost and
expense; (iv) Tenant is to promptly discharge and to indemnify and save Landlord harmless from all
liens and claims arising from such Alterations; and (v) if so requested by Landlord at the time of
approval, the Tenant will remove such Alterations and restore the Demised Premises to their
condition prior thereto by not later than the expiration or termination of this Lease. Landlords
consent for the Alterations shall be deemed to have been granted if Landlord fails to respond to
Tenants written request to make the Alterations, when submitted as required above, within two (2)
business days for Alterations estimated to cost less than $10,000.00 or within seven (7) business
days for Alterations estimated to cost more than $10,000.00. Notwithstanding the foregoing, Tenant shall have the right to make cosmetic
alterations such as painting (other than black or similarly dark colors), and carpeting throughout
the Stated Term of this Lease. Landlord shall incur no liability by approving or not approving
Tenants plans, specifications or work (such actions by Landlord and approvals and conditions
imposed for Tenants approval being solely for its own benefit and not being any assurance by 9

Landlord as to the legality or technical sufficiency or safety of Tenants plans, specifications or
work). It is agreed that all work, materials, machinery, apparatus, leasehold improvements and
other installations and alterations to the Demised Premises including, without limitation,
partitions, interior and exterior doors and door opening machinery, lighting and plumbing fixtures,
flooring, wall and window coverings, mechanical equipment for the Building, utility lines and

personal property), whether installed by Landlord or Tenant, shall at all times belong solely to
Landlord and shall not be removed by Tenant; except for such alterations and installations made by
Tenant which the Landlord requests Tenant to remove at the expiration or termination hereof. It is
also agreed that all intellectual property, biological samples, scientific instrumentation,
computers, routers, storage devices, servers, software, data, databases, and such other things
pertaining to Tenants business, research, design and development activities (or those of Tenants
collaborators, clients or affiliates) shall at all times belong solely to Tenant (or to Tenants
collaborators, clients or affiliates, as the case may be). (E) EXTERIOR MODIFICATIONS. Tenant will not make any alterations, modifications,
changes or additions to any part of the exterior of the Building, nor to the Structure, without in
each case having obtained Landlords express prior written approval thereof (which consent shall be
in Landlords exclusive discretion). Tenant will not paint, nor permit to be painted, any stone
work, cornice work, iron work, or brick work on the front or exterior of the Demised Premises or
other exterior elements of the Demised Premises or Building, without the prior written consent of
the Landlord. (F) SURRENDER OF POSSESSION. At the expiration or any termination of this Lease, or
of any hold-over term, Tenant shall surrender and deliver to Landlord possession of the Demised
Premises in the same good condition in which they were delivered at the commencement of the term
hereof (with such Alterations as may have been approved by Landlord in writing and which Landlord
does not require to be removed when Landlord grants its approval), reasonable wear and tear and
damage by casualty and condemnation excepted, broom clean with all of Tenants merchandise and
personal property removed therefrom, and free of subleases and occupants. Tenant shall deliver to
Landlord keys to all doors at the Demised Premises. Also by the expiration of the Lease, Tenant
shall deliver to Landlord a copy of an inspection report, prepared by Tenants mechanical
contractor within thirty (30) days of the expiration of the Lease, stating that the HVAC is in good
operating condition. In the event Tenant fails to maintain the Demised Premises and HVAC as
provided in Paragraph 3(C) above, or if Tenant fails to restore the Demised Premises by the
expiration of the Lease as required hereunder, then Tenant shall be liable for all reasonable third
party costs and expenses incurred by Landlord therefor, and Tenant shall pay Landlord the actual
costs incurred by Landlord to repair the Demised Premises and HVAC and/or restore the Demised
Premises plus ten percent (10%) for Landlords overhead costs. (G) MECHANICS LIENS. Tenant shall have no right to (and agrees not to) subject the
Demised Premises or the Building to any mechanics or materialmens liens of any kind for any
labor, work, materials or services ordered by, contracted for or furnished or obtained by Tenant or
any Tenant Permittees (collectively, Tenant Liens), nor to pledge the credit of or 10

indebtedness or obligations on behalf of Landlord. The Tenant agrees to indemnify, defend and hold
Landlord and the Demised Premises and Building harmless from, and to remove of record (or bond off)
within thirty (30) days after Tenants receipt of notice of the filing thereof, all Tenant Liens
and suits to enforce same and all litigation resulting from any breach by Tenant or any Tenant
Permittees of the provisions of this paragraph; and Tenant shall pay all court costs, reasonable
attorneys fees and other reasonable expenses incurred by Landlord in connection with any such
matters.  4.
    UTILITY CHARGES; PRO RATA SHARE; COMMON AREAS; OPERATING EXPENSES. (A) UTILITY CHARGES. Utility services will be brought to the Demised Premises or to
the appropriate meter room in the Building, as the case may be, and will be separately metered or
submetered (in the case of water usage), at Landlords sole cost and expense. During the entire
term hereof, Tenant shall pay, either to the supplying utility company or to the Landlord (in the
case of sub-metered utilities), all utility charges and costs of utility services of any and every
kind and nature, including, but not limited to gas, oil, water, sewer service, heat, power, fuel,
telephone service and electricity, arising out of or connected with the use and/or occupancy of the
Demised Premises or consumed thereat, promptly as same shall become due and payable, and Tenant
shall promptly make any meter deposits required by the utility companies therefor. (B) PRO RATA SHARE. It is expressly stipulated and agreed that the term Pro Rata
Share shall be defined and is agreed to mean ONE HUNDRED and 00/100 PERCENT (100.00%), which
percentage is agreed to represent the ratio that the approximate rentable floor area of the Demised
Premises bears to the total approximate rentable floor area of the entire Building ( 53,054 square
feet). (C) COMMON AREAS. Landlord shall make available Common Areas, in the Building and
on the Land on which the Demised Premises are situated. The Common Areas shall include (if

Lease, the non-exclusive right to use the Common Areas, in common with Landlord and with others
designated by Landlord as being entitled to use the Common Areas, subject to Landlords reasonable
rules and regulations established from time to time applicable to all tenants concerning the use
and operation of the Common Areas. Tenant shall comply with and advise its Permittees to comply
with said rules and regulations. Landlord shall operate, manage, repair, replace and maintain in
good condition the Common Areas for their intended purposes, all in such manner as the Landlord, in
its sole discretion, shall determine, but in all cases, in compliance with all applicable laws, statutes, ordinances and codes. All Common
Areas shall be subject to the exclusive control of Landlord. Landlord shall have the sole right
and exclusive authority to employ and discharge all personnel with respect thereto; to close
temporarily all or any portion of the Common Areas for the purpose of making repairs, changes or
alterations thereto; to perform necessary maintenance in connection with any emergency; and 11

commercially reasonably efforts to minimize any disruption to Tenants business while performing
any of its obligations herein. (D) OPERATING EXPENSES. During the term of this Lease, and any extensions and
renewals thereof, Landlord shall operate, manage, repair and maintain, in a first class manner
consistent with other similar buildings in the Gaithersburg and Germantown, Maryland areas, the

services to the Building, Land or Common Areas; and (xi) any other costs and maintenance expenses
for the Building, Land, Common Areas and all appurtenances thereto as may be deemed reasonably
necessary by Landlord which under generally accepted accounting principles properly constitute
operating or maintenance costs and expenses attributable thereto. Operating Expenses shall not include any of the following: (i) the cost of the original
construction of the Building or any additions or expansions to the Building, Common Areas or other
items which under generally accepted accounting principles are properly classified as capital
expenditures; (ii) any repairs or work performed to any portion of the Building intended to be
occupied by individual tenants; (iii) the cost of correcting any defects in the original
construction of the Building and Common Areas; (iv) any reserves for future expenditures not yet

connection with leasing the Building, and costs of the installation of signs identifying the owner
and/or manager of the Building; (xi) any costs relating to hazardous materials, asbestos and the
like not resulting from actions of Tenant; (xii) any charges for depreciation of the Building, or

Operating Expenses); (xiii) any charge for Landlords income taxes, excess profit taxes, or
franchise taxes; (xiv) Landlords general overhead attributable to the activities of Landlords
officers; (xv) expenses incurred by Landlord solely in its capacity as a partnership or other
business entity; (xvi) costs, fines or penalties incurred due to violation by Landlord of any laws
or governmental rules and regulations, except as incurred by Landlord in successfully challenging
any such law, rule or regulation for the Building or the Land; and (xvii) any costs and expenses
paid to subsidiaries of Landlord, entities under common control with Landlord, or persons related
to Landlord for services on or to the Building, but only to the extent that such costs and expenses
exceed normal costs and expenses for such services provided by unaffiliated parties to owners of
similar buildings in the Gaithersburg and Germantown areas. There shall not be duplication in
charges to Tenant by reason of the provision setting forth Tenants obligation to reimburse
Landlord for Operating Expenses and any other provision in this Lease. (E) STATEMENT OF OPERATING EXPENSES. (1) Prior to December 1st of a particular calendar year, Landlord shall make a reasonable
estimate of the Operating Expenses for the next calendar year (the Expense Estimate), and will
furnish Tenant a written statement setting forth in reasonable detail the estimate of those
Operating Expenses (the Expense Notice). For each calendar month of that next calendar year
(beginning with January 1st after the date of the Expense Notice), Tenant shall pay to
Landlord, as Additional Rent hereunder, one-twelfth (1/12th) of Tenants Pro Rata Share
of the Expense Estimate (the Tenants Monthly Share) in advance, without deduction, set off or
demand on the 1st day of each calendar month with Tenants payment of Basic Monthly
Rental. (2) Within sixty (60) days after the end of the calendar year for which the Expense Estimate
was made, Landlord shall furnish Tenant a statement setting forth in reasonable detail the actual
Operating Expenses incurred by Landlord for the previous calendar year (the Actual Expenses). If
the Actual Expenses are greater than the Expense Estimate, Landlord may increase Tenants Monthly
Share for the ensuing calendar year to reflect the Actual Expenses, and Tenant will pay to
Landlord, as Additional Rent within thirty (30) days after written demand therefor, Tenants Pro
Rata Share of the difference between the Actual Expenses and the Expense Estimate. If the Actual
Expenses are less than the Expense Estimate, either Landlord will reduce Tenants Monthly Share for
the ensuing calendar year, or Landlord will credit Tenants overpayment for Operating Expenses against the next due payment(s) of
Tenants Monthly Share and/or Basic Monthly Rental. (3) Tenant or its agent shall have the right, for a period of one (1) year after Tenants
receipt of the statement of Actual Expenses for the respective calendar year and upon giving
reasonable notice to Landlord and during normal business hours, to review and 13




---



##### 



inspect all of
Landlords bills, invoices and records applicable to the Actual Expenses or to the Expense Estimate
for that particular calendar year in order to verify the Operating Expenses. If the Landlord and
Tenant determine after said review that an error of more than five percent (5%) has been made and
the Tenant has been overcharged for Operating Expenses, then Landlord will refund the amount of the
overcharge to Tenant plus interest at the rate of eight percent (8%) per annum within thirty (30)
days after such determination. Under no circumstances will Landlord be responsible to Tenant for
Tenants cost of said review of the Operating Expenses. (4) Tenants obligation to pay Landlord its Pro Rata Share of the Operating Costs hereunder
shall survive any expiration or termination of the Lease, and shall be adjusted and pro-rated for
any portion of a calendar year occurring during the first or last Lease Year of the term hereof.  5.
    BANKRUPTCY. (A) For purposes hereof, the following shall be deemed Events of Bankruptcy of Tenant: (i)
if Tenant becomes insolvent, as defined in Title 11 of the United States Code, entitled
Bankruptcy, 11 U.S.C. Section 101 et seq. (hereinafter called the Bankruptcy Code), or under
the insolvency laws of any state, district, commonwealth or territory of the United States of
America (Insolvency Laws); or (ii) if a receiver or custodian is appointed for all or
substantially all of Tenants property or assets, or if there is instituted a foreclosure action on
all or substantially all of Tenants property; or (iii) if Tenant files a voluntary petition under
the Bankruptcy Code or Insolvency Laws; or (iv) if there is filed an involuntary petition against
Tenant as the subject debtor under the Bankruptcy Code or Insolvency Laws, which is not dismissed
within sixty (60) days of filing, or results in issuance of an order for relief against the debtor;
or (v) if Tenant makes or consents to an assignment of all or substantially all of its assets for
the benefit of creditors, or a common law composition of creditors. (B) Upon the occurrence of an Event of Bankruptcy, or if Tenant becomes insolvent pursuant to
any Insolvency Laws, then in any such event Landlord at its option and sole discretion may
terminate this Lease by written notice to Tenant (subject, however, to applicable provisions of the
Bankruptcy Code or Insolvency Laws during the pendency of any action thereunder involving Tenant as
the subject debtor). If this Lease is terminated under this paragraph, Tenant shall immediately
surrender and vacate the Demised Premises, waives all statutory or other notice to quit, and agrees
that Landlords obligations under this Lease shall cease from such termination date, and Landlord
may recover possession by process of law or in any other lawful manner. Furthermore, if this Lease
terminates under this paragraph, Landlord shall have all rights and remedies against Tenant
provided in case of defaults of Tenant in payment of rent. (C) If Tenant becomes the subject debtor in a case pending under the Bankruptcy Code,
Landlords right to terminate this Lease under this paragraph shall be subject to the applicable
rights (if any) of the Trustee in Bankruptcy to assume or assign this Lease as then provided for in
the Bankruptcy Code. However, the Trustee in Bankruptcy must give to Landlord and Landlord must
receive proper written notice of the Trustees assumption or rejection of this Lease within sixty
(60) days after the date of the Trustees appointment; it being 14




---



##### 



agreed that failure of the Trustee
to give notice of such assumption hereof within said sixty (60) days period shall conclusively and
irrevocably constitute the Trustees rejection of this Lease and waiver of any rights of the
Trustee to assume or assign this Lease. The Trustee shall not have the right to assume or assign
this Lease unless said Trustee (i) promptly and fully cures all defaults under this Lease, (ii)
promptly and fully compensates Landlord for all monetary damages incurred as a result of such
default, and (iii) provides to Landlord Adequate Assurance of Future Performance, (as defined
herein below). Landlord and Tenant hereby agree in advance that Adequate Assurance of Future
Performance, as used in this Paragraph, shall mean that all of the following minimum criteria must
be met: (a) the Tenant or the Trustee must pay to Landlord, at the time the next payment of Rent
is then due under this Lease, in addition to such payment of Rent, an amount equal to the next four
(4) months Rent due under this Lease, said amount to be held by Landlord in escrow until either the
Trustee or Tenant defaults in its payment of Rent or obligations under this Lease (whereupon
Landlord shall have the right to draw on such escrowed funds) or until the expiration of this Lease
(whereupon the funds shall be returned to the Trustee or Tenant within 30 days thereafter, if
Tenant is not in default hereunder); (b) the Tenant or Trustee must agree to pay to Landlord, at
any time the Landlord is authorized to and does draw on the funds escrowed pursuant to clause (a)
of this Subsection 5(C) (iii) the amount necessary to restore such escrow account to the original
level required by said provision; (c) Tenant must pay to Landlord all rentals and other sums
payable by Tenant hereunder including also therein its share (as estimated by Landlord) of the cost
of all services provided by Landlord (whether directly or through agents or contractors, and
whether or not the cost of such services is to be passed through to Tenant), in advance of the
performance or provision of such services, and (d) the Tenant or Trustee must agree that the use of
the Demised Premises as stated in this Lease will remain unchanged, and that the assumption or
assignment of this Lease will not violate or affect the rights of other Tenants in the Building.
In the event Tenant is unable to: (i) cure its defaults, (ii) reimburse Landlord for its monetary
damages, (iii) pay the Rents due under this Lease or any other payments required of Tenant under
this Lease on time, or (iv) meet the criteria and obligations imposed by (a) through (d) above in
this Paragraph 5(C), then Tenant hereby agrees in advance that it has not met its burden to provide
Adequate Assurance of Future Performance, and this Lease may be terminated by Landlord in
accordance with Paragraph 5(B) above. Notwithstanding the above, the Security Deposit shall count
towards the amount required for Adequate Assurance of Future Performance. (D) It is further stipulated and agreed that, in the event of the termination of the term of
this Lease by the happening of any such event described in this Section 5, Landlord shall
forthwith, upon such termination, and any other provision of this Lease to the contrary
notwithstanding, become entitled to recover as and for damages caused by such termination all
amounts permitted by applicable law.  6.
    INSURANCE. (A) It is further understood, agreed and covenanted by and between the parties hereto that
the Tenant will be responsible for any claim for damages arising from injury or any claim of death
or injury to persons or damage to property at or upon said Demised Premises caused or occasioned
directly or indirectly by Tenants or any Permittees use or occupancy of said Demised Premises,
and that the Tenant, unless such claim or damage is due to Landlords 15




---



##### 



negligence or willful
misconduct, will and does hereby agree to defend, indemnify and hold harmless the Landlord, its
partners and agents and its and their successors and assigns from and against any and all
liability, damages, expenses, claims, suits, actions or causes or rights of action arising from or
caused by any such damages or injury or claim for damages or injury (including death) to persons or
property at or upon said Demised Premises during the Initial Term and any renewal or extension
thereof. In confirmation thereof, the Tenant covenants and agrees that it will at all times during
the term of this Lease, at its own expense, carry and maintain in full force and effect, in
companies reasonably satisfactory to Landlord, Commercial General Liability insurance, with limits
of at least a $1,000,000.00combined single limit, for bodily injury, including death, to any one
or more person(s) in any single occurrence and for property damage or in such greater amounts of
coverage as Landlord may from time to time reasonably require, naming the Landlord as additional
insured. Each policy shall contain the Broad Form General Liability Endorsement. Each policy or a
Certificate of Insurance showing the same to be in effect for a one (1) year period, shall be
delivered to Landlord within thirty (30) days of the Commencement Date, and renewal certificates
shall be delivered to Landlord at least fifteen (15) days prior to expiration of any such policy,
and each such policy shall contain an endorsement requiring at least thirty (30) days prior written
notice to all named insureds as to any cancellation, non-renewal or adverse modification of any
such policy. It is specifically covenanted and agreed by the Tenant that there shall be no
abatement of Rent because of any damage caused by fire or other peril, except as provided in
Section 9. The amount of such insurance shall not limit Tenants indemnity obligations under this
Section 6 or under any other provision of this Lease. Tenants indemnity obligations under this
section and elsewhere contained in this Lease shall survive expiration or termination of this
Lease. (B) It is further understood, agreed and covenanted by and between the parties hereto that
the Landlord will be responsible for any claim for damages arising from injury or any claim of
death or injury to persons or damage to property at or upon the Common Areas caused or occasioned
directly or indirectly by Landlords management of said Common Areas, and that the Landlord will
and does hereby agree to defend, indemnify and hold harmless the Tenant, its partners and agents
and its and their successors and assigns from and against any and all liability, damages, expenses,
claims, suits, actions or causes or rights of action arising from or caused by and such damages or
injury or claim for damages or injury (including death) to persons or property at or upon said
Common Areas during the Initial Term and any renewal or extension thereof.  7.
    SUBLETTING AND ASSIGNMENT. (A) It is further understood, agreed and covenanted by and between the parties hereto that
the Tenant shall have no right to, and will not, transfer or assign this Lease, or sublet or
transfer possession of said Demised Premises, or any part thereof, voluntarily, or involuntarily, whether by operation of law, in bankruptcy or otherwise, without the prior
written consent of the Landlord. If, during any Renewal Term or holdover term, Tenant desires to
assign this Lease or to sublet the entire Demised Premises to other than an Affiliate or Tenant
Successor, as those terms are defined below, then in any such event, the Landlord shall have the
right (and such right is hereby expressly reserved unto Landlord) in its sole discretion, but not
the obligation, by written notice given to Tenant within twenty (20) days from Landlords receipt 16




---



##### 



of a written proposal for such assignment or sublease, to cancel and terminate this Lease and
recover possession of the Demised Premises. Any assignment or subletting and any consent of
Landlord thereto shall not release Tenant of any liability under this Lease, and shall not waive
the obligation to obtain Landlords consent to any further assignment or subletting. Any
assignment or subletting, including the use of the Demised Premises by the assignee or subtenant,
shall be subject to all of the terms and provisions of this Lease. Tenant shall pay to Landlord,
as Additional Rent within thirty (30) days of demand by Landlord therefor, any reasonable third
party expenses incurred by Landlord with respect to the review and consent or denial of consent of
the foregoing. (B) Notwithstanding the provisions of Paragraph 7(A) hereof (except regarding the recapture
right of Landlord), Landlord agrees that it will not delay or condition or withhold unreasonably
its consent to a proposed assignment of this Lease or subletting of all or any portion of the
Demised Premises by Tenant provided that all of the following conditions and all such other
conditions as Landlord reasonably may impose (collectively, the Transfer Conditions) are met:
(a) Tenant is not in an Event of Default under this Lease or under any other lease from Landlord or
from Related Owners (defined below); (b) Tenant is not subject to any Events of Bankruptcy; (c)
Tenant is in possession and occupancy of the Demised Premises; (d) the Initial Term of the Lease
and Tenants payment of Rent hereunder have commenced; (e) (i) the proposed assignee has a net
worth at least equal to the net worth of Tenant as of the date of this Lease (the Minimum Net
Worth), (ii) the proposed assignee or sublessee has a good business reputation and adequate
experience in operating its business, (iii) the proposed assignee or sublessee operates a quality
and type of business which is compatible with the business and type of other tenants of space in
the Building and in Seneca Meadows Corporate Center, (iv) the proposed assignee or sublessee shall
not be a party which has been in default under any other leases of space owned by nor under any
other agreements of any kind with Landlord or any entities in which Landlords partners or any of
them have or had ownership interests (Related Owners), and (v) the proposed assignee or sublessee
is not a party with whom Landlord or any Related Owners is or are negotiating a lease of space in
the Building or in any other property; (f) the use of the Demised Premises shall not be changed
from the use permitted in Paragraph 3(A) of this Lease as a result of any such assignment or
subletting; (g) Tenant shall have delivered to Landlord evidence reasonably satisfactory to
Landlord that all Transfer Conditions are or will promptly be met (the Transfer Evidence); (h)
the prior written consent (if required) of Landlords mortgagees to the proposed assignment or
subletting (if required under the loan documents) shall have been obtained at Tenants expense and
at no cost to Landlord nor change in provisions of the loan documents (the Lenders Consent); and
(i) Tenant shall have delivered to Landlord an instrument of assignment or sublease (as the case
may be) in form and content acceptable to Landlords mortgagees and reasonably acceptable to
Landlord, executed by the assignee or sublessee, by which the assignee or sublessee (to the extent
applicable) assumes all obligations of Tenant under and agrees to be bound by and comply with this
Lease. Nevertheless, if Tenant proposes to sublet the entire Demised Premises or to assign this Lease
(except to an Affiliate of Tenant or to a Tenant Successor, as defined below), then Landlord shall
continue to have the right, pursuant to Paragraph 7(A) hereof, to cancel this Lease and recover
possession of the Demised Premises. Any such assignment or subletting consented to by Landlord
shall be subject to all terms and provisions of this Lease, shall not waive the necessity of
obtaining Landlords prior written consent for any further assignment and subletting, shall not 17

##### 



relieve or reduce Tenants primary liability to Landlord under this Lease, and shall not result in
any change in the permitted use of the Demised Premises. (C) It is further agreed that, provided all Transfer Conditions are met, Landlord will
consent to Tenants sublease of the Demised Premises to an Affiliate of Tenant (as defined below)
or to assignment of this Lease to a Tenant Successor (as defined below) subject however to all of
the terms and provisions of this Lease, including but not limited to those contained in Paragraph
7(B) hereof. The phrase Affiliate of Tenant, as used herein, means a corporation or other legal
entity which is under common ownership, management and/or control with Tenant. For purposes of
this Paragraph 7(C), the phrase Tenant Successor shall mean a person or entity who or which
acquires and succeeds to ownership of all, or substantially all, of Tenants business as a result
of either (i) purchase of all or substantially all of Tenants assets, or (ii) purchase of all or
substantially all issued and outstanding shares of capital stock in Tenant (the Acquisition).
Tenant agrees to provide Landlord the Transfer Evidence when Tenant requests Landlords consent to
a sublease of all or a part of the Demised Premises to an Affiliate of Tenant. Tenant agrees to
provide Landlord the Transfer Evidence and evidence of the Acquisition when Tenant requests
Landlords consent to an assignment of this Lease to the Tenant Successor. It is further agreed
that if Landlord consents to such assignment of the Lease to the Tenant Successor, and provided
that all Transfer Conditions are met and that the Tenant Successor has a net worth at least equal
to the greater of (a) the net worth of Tenant immediately prior to consummation of the Acquisition,
or (b) the Minimum Net Worth aforesaid, and is not subject to any Events of Bankruptcy, and
provided Tenant has furnished evidence reasonably satisfactory to Landlord to confirm the financial
condition of such assignee Tenant Successor, and further provided that Lenders Consent (as defined
and under the terms set forth above) to such release of liability has been obtained, then in such
event Landlord will join with Tenant and its Tenant Successor in executing an instrument reasonably
acceptable to Landlord by which (A) Tenant is released of all liability under this Lease accruing
after the effective date of the assignment hereof to the Tenant Successor (the Effective Transfer
Date), and (B) the Tenant Successor assumes all obligations of Tenant under this Lease. However,
no such release instrument shall relieve Tenant of any indemnification obligations to Landlord
under this Lease covering periods prior to the Effective Transfer Date. Landlord and Tenant agree
to use reasonable efforts to obtain the Lenders Consent described above in Paragraphs 7(B) and
7(C). (D) With any request for Landlords consent to an assignment or subletting, Tenant shall
provide Landlord a copy of the proposed instrument of assignment or sublease in form and content
reasonably acceptable to Landlord and legally binding upon and enforceable against Tenant and the
assignee or sublessee, together with such additional information as Landlord reasonably may
require.  8.
    PAYMENT OF REAL ESTATE TAXES AND INSURANCE COSTS. (A) Tenant covenants and agrees that it will, during the entire term of this Lease, pay to
Landlord as Additional Rent hereunder, in addition to the Basic Annual Rental payable under
Paragraph 1(C) hereof, the Operating Expenses payable to Landlord under Section 4 hereof and the
other sums payable by Tenant under the Lease, within thirty (30) daysafter each and every demand
by Landlord therefor, the Tenants Pro Rata Share of any and all real estate 18

##### 



taxes and assessments
and similar impositions, general and special, ordinary and extraordinary, which may be levied,
assessed or payable (for or allocable to periods of time within the term of this Lease and any
renewal, extended and holdover term), upon the Building in which the Demised Premises are situated
and/or the Land serving and/or on which is erected said Building, and including also all reasonable
fees and expenses of attorneys, accountants and consultants and other expenses including but not
limited to court costs and appeals, incurred by Landlord in contesting any such items
(collectively, the Impositions). The amount of said Impositions (of which Tenant is to pay its
Pro Rata Share, as aforesaid) as shown on the government-issued tax bills or assessment notices,
shall be deemed conclusive evidence of the amount of said Impositions. If the amount of the
Impositions payable by Landlord on the Building and Land is reduced by any abatement attributable
to Tenants occupancy of the Demised Premises, such as the Miller Legislation, then Tenant shall
receive the full amount of said abatement attributable to its occupancy. Landlord agrees that
Tenant shall have the right to appeal any assessments or Impositions at Tenants sole cost and
expense in the event Landlord declines to do so; in which event, Landlord agrees to promptly notify
Tenant of its decision and to provide Tenant reasonable assistance during such Tenants appeal. (B) Tenant hereby further covenants and agrees that it will, during the entire term of this
Lease, pay to Landlord as Additional Rent hereunder, in addition to the Basic Annual Rental payable
under Paragraph 1(C) hereof; the Operating Expenses payable to Landlord under Section 4 hereof and
the other sums payable by Tenant under the Lease, within thirty (30) daysafter each and every
demand by Landlord therefor, the Tenants Pro Rata Share of any and all premiums, costs,
deductibles and other charges and expenses incurred, paid, accrued or absorbed by Landlord for or
in connection with all policies of fire, extended coverage, hazard and general liability insurance
and other insurance carried or maintained by Landlord on the Demised Premises and/or the Building
and Land of which they form a part (collectively, the Insurance Premiums). The insurance which
Landlord shall carry and with respect to which Tenant shall make said payments shall include
without limitation rent interruption, fire and extended coverage, general liability with umbrella
coverage, and supplemental equipment coverage (for boilers, pressure vessels, HVAC and electrical
equipment) and all such other insurance coverages and in such amounts as are maintained by prudent
owners of property similar to the Building, all as reasonably determined by Landlord. (C) Landlord agrees that it will pay the Impositions and the Insurance Premiums as same
become due and payable (subject to Tenants reimbursements of its Pro Rata Share thereof, as
aforesaid). (D) Failure of Tenant to pay to Landlord any such sums due under this Section 8 when due and
after notice of Monetary Default shall constitute an Event of Default of Tenant under this Lease.
The obligations of Tenant under this Section 8 shall survive any cancellation, expiration or
termination of this Lease, as regards any such payments due from Tenant hereunder as of the date of
such cancellation, expiration or termination or allocable to periods while this Lease is in force.
The sums payable by Tenant under this Section 8 shall be appropriately adjusted, apportioned and
paid by Tenant for any fraction of a governmental tax year or insurance policy year occurring at
the commencement and at the expiration of the term of this Lease. 19

9.
    DAMAGE BY FIRE, OTHER CASUALTY, OR SERVICE INTERRUPTION. (A) In the event that the Demised Premises should be damaged by fire or other casualty so
that the same shall be rendered partially untenantable, such damage shall be repaired by the
Landlord as promptly as is reasonably possible, and the Rent shall be abated (from the date of such
damage until the damage is repaired) in the same proportion as the area of the Demised Premises
rendered untenantable bears to the total area of the Demised Premises. The Landlord shall not be
held liable in damages or otherwise for any delay in making or completing said repairs, whether or
not caused by time necessary to settle insurance claims, nor strikes, acts of God or other
casualties or any circumstances. (B) In the event that the Demised Premises shall be substantially (i.e., 40% or more of the
demised space) destroyed or rendered totally untenantable, or if Landlords mortgage lender does
not make adequate insurance proceeds available to Landlord to pay for the costs of repairs and
restoration, then in any such event the Landlord shall have the option in its sole discretion of
rebuilding the Demised Premises, or of not rebuilding the Demised Premises and instead canceling
this Lease. The Landlord, in exercise of such option, shall determine whether or not to rebuild
and shall notify Tenant of such determination in writing, within sixty (60) days after such damage
or destruction. If Landlord shall determine to rebuild or repair such damage or destruction,
Landlord agrees to make such repairs with reasonable promptness and dispatch, and the Rent shall
abate (from the date of the damage or destruction until the repairs required of Landlord under this
paragraph are Substantially Complete) in proportion to the area of said Demised Premises rendered
untenantable. If the Landlord determines to rebuild as aforesaid, this Lease shall not be
canceled, but instead shall remain in full force and effect and Tenant shall reoccupy the Demised
Premises (and Rent abated as aforesaid shall again accrue and be payable) when the repairs required
of Landlord under this paragraph are substantially complete. If Landlord elects to cancel this
Lease under this paragraph, then Rent and all other sums payable by Tenant under this Lease shall
be adjusted, pro-rated and paid by Tenant to the date of such damage. Any repair and restoration
to be performed by Landlord under this Section 9 shall be limited to those portions of the Demised
Premises which were constructed by Landlord; it being agreed that when Landlord completes its
repairs thereof to be made pursuant to this Section 9, all Rent (if any) abated under this Section
9 shall again commence to be due and payable. Tenant, at its own expense, will repair or replace
any damage to its furniture, merchandise, trade fixtures, equipment, personal property and other items belonging to Tenant if damaged or destroyed by
fire or other casualty, and also all leasehold improvements constructed by Tenant. (C) Notwithstanding the above, if the repairs which Landlord is to make under this Section 9
are not substantially completed within two hundred seventy (270) days after the date of the
destruction of or damage to the Demised Premises, and provided that Tenant is not in an Event of
Default and that such damage or destruction was not caused by the intentional act of Tenant or its
Permittees, then in such event Tenant at its option may terminate this Lease by giving written
notice to Landlord within ten (10) days after the end of the two hundred seventy (270) day period
aforesaid. However, Tenants notice of termination hereof shall be ineffective if Landlord
completes the restoration of the Demised Premises prior to Landlords receipt of such termination
notice. 20

##### 



(D) In the event that the Demised Premises are rendered untenantable due to the loss or
disruption of utility service (water, sanitary sewer, storm sewer, gas, electric, or telephone),
which loss or disruption is caused by the negligence or willful misconduct of Landlord or any
Landlord Parties (as that term is defined herein), such utility service shall be restored by
Landlord as promptly as is reasonably possible, and the Rent shall be abated (from the date of such
loss of service until the restoration of said service is completed) in the same proportion as the
area of the Demised Premises rendered untenantable bears to the total area of the Demised Premises.
Landlord shall not be held liable in damages or otherwise for any delay in making or completing
such restoration of utility service.  10.
    COMPLIANCE WITH LAWS, ETC. Tenant, at its own expense, will promptly comply with, observe and perform all of the
requirements of, and will obtain and maintain in force all licenses, permits and other
authorizations required by, all of the statutes, ordinances, rules, orders and regulations, now in
effect or hereafter promulgated, concerning the use or occupancy of the Demised Premises and/or the
conduct of Tenants business, and whether required by federal, state, county or town governments
and whether required of the Tenant or Landlord (collectively, Laws). The Tenant agrees that it
will promptly comply, at its own expense, with all rules, orders and regulations of the Board of
Fire Underwriters having jurisdiction for the prevention of fire, and other hazards, applicable to
said Demised Premises, or for the preservation of the Demised Premises, or the correction or
abatement of nuisances or grievances for which either the Landlord or the Tenant may be responsible
as a result of Tenants use and occupancy of the Demised Premises during the term of this Lease,
and Tenant shall at its own expense comply with all reasonable rules, regulations and requirements
of Landlords and Tenants insurance carriers concerning Tenants use and occupancy of the Demised
Premises and conduct of its business therein (collectively, Insurance Requirements). Tenant
shall not place or store in the Demised Premises, nor deposit in any utility lines thereof, any
hazardous or toxic substances, materials or any items which violate any applicable federal, state,
or local environmental protection laws, and Tenant will indemnify, defend and hold Landlord
harmless from all liability and expense arising from Tenants violation of this Section 10.  11.
    NON-WAIVER OF BREACH. (A) The failure of Landlord 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, or
to serve any notice, or to institute any action or summary proceedings, or otherwise to act as
though this Lease had expired pursuant to any of the provisions of this Lease, shall not be
construed as a waiver or relinquishment by Landlord for the future, of such covenant or option, or
right thereafter to serve notice and to have this Lease expire under any provision of this Lease,
but such covenant or option 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 Landlord of any provision hereof shall be deemed to have been
made, unless expressed in writing and signed by Landlord or its duly authorized agent. The rights
and remedies herein created are cumulative, and the use of one remedy shall not be taken to exclude
or waive the right to the use of another. 21

(B) The failure of Tenant to insist, in any one or more instances, upon a strict performance
of any of the covenants required of Landlord under this Lease, or to serve any notice, or to
institute any action or summary proceedings, shall not be construed as a waiver or relinquishment
by Tenant for the future of such covenant or right thereafter to serve notice under any provision
of this Lease, but such covenant shall continue and remain in full force and effect. The rights
and remedies herein created are cumulative, and the use of one remedy shall not be taken to exclude
or waive the right to the use of another.  12.
    EVENT OF DEFAULT; REMEDIES; RELETTINGS; LEGAL COSTS; INTEREST; ACCORD AND
SATISFACTION; CONCESSIONS; DEFAULT UNDER OTHER LEASES. (A) EVENT OF DEFAULT. It is hereby mutually covenanted and agreed, that any or all
of the following shall be an Event of Default by Tenant: (i) if Tenant should fail to pay promptly when and as due any payment of Basic Monthly Rental,
Additional Rent or other sums payable by Tenant hereunder (a Monetary Default), and if such
Monetary Default is not fully cured within five (5) business days after written notice thereof from
Landlord to Tenant (except that Landlord need not give Tenant more than two (2) notices of
non-payment of monthly rent installments in any one Lease Year, it being agreed an Event of Default
shall exist without regard to such notice as concerns more than two (2) monthly rent defaults in a
Lease Year); or if Tenant shall fail promptly and timely to keep and perform each and every
covenant, condition and agreement not involving payment of money (a Non-Monetary Default) herein
contained and on the part of Tenant to be kept and performed, and if such Non-Monetary Default is
not fully cured within thirty (30) days after written notice from Landlord to Tenant (or within
such additional time as reasonably needed to cure same if Tenant acts diligently to and does cure
same promptly and holds Landlord harmless from all liability and expense arising from such default and the existence thereof is
not a default under any deed of trust on the Demised Premises (about which Tenant has been
notified) and does not materially adversely affect the value, safety or security of the Demised
Premises nor cause unreasonable disturbance to other tenants of neighboring buildings); or if
Tenant fails to keep in force any insurance herein required and such default is not cured within
five (5) business days after written notice, or if any act or omission of Tenant causes
unreasonable interference with the use, occupancy or quiet enjoyment of any other tenant of any
neighboring building and is not abated within five (5) days after written notice from Landlord; or (ii) if the Tenants estate hereby created shall be taken on execution or other process or
law; or (iii) if there shall occur any of the events described in Section 5 hereof which entitle
Landlord to terminate this Lease pursuant to said Section 5; (B) REMEDIES. In each and every such Event of Default, from thenceforth and at all
times thereafter, at the exclusive and absolute option and discretion of Landlord, the Tenants
right of possession of the Demised Premises shall thereupon cease and terminate, and Landlord shall
be entitled to the immediate possession of the Demised Premises and to remove 22




---



##### 



all persons and property therefrom and to re-enter the same without further demand of Rent or demand of possession
of said Demised Premises, with process of law and without becoming liable to prosecution therefor,
any statutory or other notice to quit or of intention to re-enter being hereby expressly waived by
Tenant; and in the event of such re-entry or retaking by Landlord, Tenant shall nevertheless remain
in all events liable and answerable for the full Rent to the date of retaking or re-entry. Tenant
shall also be and remain answerable in damages for the deficiency or loss of Rent which Landlord
may thereby sustain in respect of the balance of the term; and in such case Landlord reserves full
power, which is hereby acceded to by Tenant, to re-let said Demised Premises or any portion(s)
thereof as Landlord may select, upon such terms and rentals as Landlord may deem proper (which
re-lettings may be for a term lesser or longer than the term of this Lease, at Landlords exclusive
discretion), all at the risk and cost and for the benefit of Tenant in liquidation and discharge,
in whole or in part, as the case may be, of the liability of Tenant under the terms and provisions
of this Lease, and such damages, at the option of the Landlord, may be recovered by it at the time
of the retaking or re-entry, or in separate actions, from time to time, as Tenants obligation to
pay Rent would have accrued if the term had continued, or from time to time, as said damages shall
have been made more easily ascertainable by relettings of the Demised Premises, or such action by
Landlord may at the option of Landlord be deferred until the expiration of the term, in which
latter event the cause of action shall not be deemed to accrue until the date of the termination of
said term. (C) RELETTINGS. All rents received by Landlord in any such reletting shall be
applied first to the payment of such expenses as Landlord may have incurred in recovering
possession of the Demised Premises and in reletting the same, including also brokerage commissions
and fees and costs of renovations and alteration of the Demised Premises, second, to the payment of
any costs and expenses incurred by Landlord, including also making necessary repairs to the Demised
Premises or in curing any default on the part of Tenant in any covenant or condition herein made
binding upon Tenant, and, last, any remaining rent shall be applied toward the payment of Rent due from Tenant under the terms of this Lease, with interest at the rate
of fifteen percent (15%)per annum or at the highest lawful rate under then applicable Maryland
laws, whichever is less, and Tenant expressly agrees to pay any deficiency then remaining.
Landlord, however, at its option, may refrain from terminating Tenants right of possession, and in
such case may enforce against Tenant the provisions of this Lease for the full term thereof. (D) LEGAL COSTS. In any action or proceeding which the Landlord or the Tenant may be
required to prosecute to enforce its respective rights hereunder, the unsuccessful party therein
agrees to pay all costs incurred by the prevailing party therein, including reasonable attorneys
fees, to be fixed by the court, and said costs and attorneys fees shall be made a part of the
judgment in said action. In any situation in which a dispute is settled other than by action or
proceeding, the parties shall pay their respective costs and attorneys fees relating thereto. If
Landlord is the prevailing party in any action or proceeding against Tenant, then Tenants payment
of Landlords costs and attorneys fees relating thereto shall be considered a payment of
Additional Rent. (E) INTEREST. If a Monetary Default by Tenant occurs under any terms of this Lease,
Tenant shall pay Landlord, in addition to the amount so in default and any Late Charges that may be
applicable, interest at the rate of fifteen percent (15%)per annum, or the highest 23




---



##### 



lawful rate,
whichever is less (the Default Interest Rate), from the date the payment was due until the date
Landlord receives said payment. If a Non-Monetary Default by Tenant occurs under any provisions of
this Lease, Landlord at its sole option and discretion may take the action to cure such
Non-Monetary Default (without any obligation to do so) in addition to and without waiving any other
remedies, and Tenant will reimburse Landlord promptly on demand for all reasonable costs incurred
by Landlord plus interest at the Default Interest Rate from the date Landlord pays for such
incurred costs until the date Landlord receives payment from Tenant. (F) ACCORD AND SATISFACTION. No receipt and retention by Landlord of any payment
tendered by Tenant in connection with this Lease will give rise to or support or constitute an
accord and satisfaction, notwithstanding any accompanying statement, instruction or other assertion
to the contrary (whether by notation on a check or in a transmittal letter or otherwise), unless
Landlord expressly agrees to an accord and satisfaction in a separate writing duly executed by the
appropriate persons. Landlord may receive and retain, absolutely and for itself, any and all
payments so tendered, notwithstanding any accompanying instructions by Tenant to the contrary.
Landlord will be entitled to treat any such payments as being received on account of any item or
items of Rent, interest, expense or damage due in connection herewith, to be applied in such
amounts and in such order as Landlord may determine at its sole option. (G) CONCESSIONS. Any abatements of Rent or other economic incentives (such as moving
allowances, the cost of performing Landlords Work, brokerage fees, or any other cash payments or
allowances) made by Landlord to or on behalf of Tenant in conjunction with this Lease (the
Concessions) are subject to the condition that during the Initial Term of the Lease, Tenant will
faithfully comply with all of the terms and conditions of the Lease. If, after an Event of
Default, Landlord terminates the Lease and takes possession of the Demised Premises to mitigate its
damages, then Tenant shall reimburse Landlord as Additional Rent for the cost of the Concessions
multiplied by a fraction, the numerator of which shall be the number of months remaining in the Initial Term after the Event of Default occurs, and the denominator
of which shall be the number of months in the Initial Term of this Lease. Notwithstanding the
above, under no circumstances shall Landlord be allowed to recover any damages for Concessions that
are included in any other damages awarded to and collected by Landlord pursuant to the provisions
of this Lease. (H) DEFAULT UNDER OTHER LEASES. It is further understood and agreed that if Tenant
is in default or breach beyond any applicable grace or cure periods under any other lease or leases
between Tenant as tenant and Landlord or any partnership, joint venture, corporation or other
entity or parties affiliated with Landlord in which Landlords partners or any of them has an
ownership interest, then in any such event such default or breach shall constitute an Event of
Default by Tenant under this Lease at the option and exclusive discretion of Landlord, entitling
Landlord to exercise any or all rights and remedies provided herein (including without limitation
those in Section 12 hereof), in addition to and without limitation of any rights and remedies under
such other lease(s). 24

13.
    LANDLORDS LIABILITY. If Landlord shall sell, convey or otherwise transfer or dispose of the Demised Premises and/or
the Building in which same is located, and if the purchaser then assumes all obligations of the
Landlord under this Lease (including any obligation to return Tenants Security Deposit), then the
undersigned Landlord shall be deemed to be released of all obligations hereunder, effective from
and after the date of such transfer. Landlords liability under this Lease shall be limited to its
ownership interest in the Building. However, in no event shall any partners in Landlord ever have
any personal liability under this Lease, nor may this Lease be enforced against any such partners
in Landlord, nor shall Tenant have any recourse to any assets or properties of any partners in
Landlord for enforcement of any provisions of this Lease.  14.
    TENANTS SIGNS. Tenant shall have the exclusive right (except as provided in Section 15 below), with
Landlords consent, to install signage on the Building, in compliance with applicable Laws and the
covenants restricting same in Seneca Meadows Corporate Center, identifying Tenant as the occupant
of the Building. Tenant shall not place any signs or other forms or kinds of advertising in or
about the Demised Premises, which may be visible from the exterior thereof, without Landlords
prior written consent in each instance. Any signs installed by Tenant shall be installed at its
own expense and in compliance with all applicable laws, and shall be removed by Tenant by the
expiration or termination hereof, with all damage to Landlords property repaired by and at the
expense of Tenant. Landlord shall install, at its own expense, monument signs along Goldenrod Lane
identifying the tenants in Seneca Meadows Corporate Center, all as permitted by applicable Laws.  15.
    LANDLORDS SIGNS. Tenant agrees that Landlord and its agents shall have the right to place a For Lease sign in
the front or exterior of the Demised Premises at all times during the last six (6) months of the
term hereof, and a For Sale sign at any time, provided said signs do not block the visibility of
Tenants signs and do not interfere with Tenants use of the Demised Premises. Tenant will not
disturb or obstruct visibility of any such signs.  16.
    ENTRY AND ACCESS. (A) Tenant further agrees that the Landlord and/or its representatives, contractors and
employees shall have the right at all reasonable times, during business hours and with prior notice
of the identity and affiliation of any representatives, contractors, prospective tenants and
employees, and if accompanied by an escort of Tenant, if Tenant so desires, and at any time without
notice or escort in emergencies, to enter upon the Demised Premises to inspect the same or make
engineering surveys, exploratory excavations, repairs, alterations and additions, and to perform
any work required of Landlord under this Lease or which Landlord deems necessary for the safety or
preservation of the Demised Premises or of the Building, including also any work required of Tenant
in respect of which Tenant is in an Event of Default. Tenant also agrees to 25




---



##### 



permit Landlord and/or
its agents to show the Demised Premises to prospective tenants at all reasonable times after prior
notice and accompanied by an escort of Tenant during the last six (6) months of the term hereof and
any time after Tenant has given Landlord notice of termination of this Lease under any provision
hereof entitling Tenant to do so, or if Tenant is in an Event of Default or subject to any Events
of Bankruptcy. During any of the foregoing entries into the Demised Premises, Landlord agrees to
exercise commercially reasonable efforts to minimize any disruption to Tenants business. (B) If Tenant shall have vacated and abandoned the Demised Premises, then the Landlord and/or
its representatives, contractors and employees shall have the right to enter the Demised Premises,
by force or otherwise if necessary and without being liable therefor, and without in any manner
affecting Tenants obligations under the Lease. The exercise of such reserved right by Landlord
shall not be deemed a disturbance of Tenants right of Quiet Possession under the Lease, shall not
affect Tenants obligation to pay Rent under the terms of the Lease, shall not be deemed to
constitute actual or constructive eviction, and shall not subject Landlord to any liability to
Tenant therefor. 17. EMINENT DOMAIN. Tenant agrees that if the said Demised Premises, or any part thereof, shall be taken,
condemned or acquired for public or quasi-public use or purpose by any competent authority, whether
by condemnation proceedings, lease or purchase, Tenant shall have no claim against Landlord and
shall not have any claim or right to any portion of the amount that may be awarded as damages or
paid as a result of any such condemnation, lease or purchase; it being agreed that the full amount
of such award, or other proceeds, if any, made or paid by the taking authority shall be paid to and
retained by Landlord free of any claim by Tenant to any portion thereof; and all right of Tenant to
damages therefor, if any, are hereby assigned by Tenant to Landlord. Should all or a substantial
part of the Demised Premises be so taken or acquired, the term of this Lease shall cease and
terminate from the date of the taking, and Tenant shall have no claim against Landlord for the value of any unexpired term of this Lease or for any other
matters. All Rent and other sums payable by Tenant hereunder shall be adjusted and paid by Tenant
to the date on which Tenant is required, by said taking authority, to surrender possession of said
Demised Premises. However, if the portion of the Demised Premises so taken or acquired does not
render the Demised Premises unusable for the purposes herein permitted, then this Lease shall not
terminate, but shall continue in effect with the Rent reduced in proportion to the area of the
Demised Premises so taken or acquired. Notwithstanding the foregoing provisions of this Section
17, Tenant shall have the right at its own expense, and in a separate action from Landlords
condemnation proceedings, to pursue against the condemning authority claims for Tenants leasehold
improvements which exceed the value of the Tenant Improvement Allowance, relocation expenses and
other losses (excluding loss of the leasehold) necessitated by such taking of the Demised Premises,
provided that no such claim of or award to Tenant shall reduce, delay, interfere with or otherwise
in any manner adversely affect any claims of or award to Landlord for taking of Landlords interest
in the Demised Premises, this Lease, the Building, the Land appurtenant thereto or any other claims
to which Landlord is entitled. 18. CONSENT. 26




---



##### 



Whenever the consent or approval of the Landlord or Tenant is required under this Lease, such
consent will not be unreasonably withheld, conditioned or delayed, except as otherwise herein
provided for exclusive discretion given to Landlord. The party giving its consent, or the reasons
for not giving consent, shall respond in writing to the other partys request for consent within
ten (10) business days of its receipt of such request (but, except as expressly provided herein,
shall not be deemed to grant such consent nor to waive any rights by failing to respond within said
period). 19. TENANTS PROPERTY. The Tenant further covenants and agrees that all personal property in and upon the Demised
Premises shall be and remain there at Tenants sole risk, and the Landlord and its partners, agents
and employees (collectively, Landlord Parties) shall not be liable for any damage to or loss of
any personal property arising from any acts or negligence of any other persons, nor from the
leaking of the roof, nor from the bursting, leaking or overflowing of water, sewer or steam pipes,
nor from heating or plumbing fixtures, nor from the handling of electric wires or fixtures, nor
from any other cause whatsoever (unless and only to the extent caused by the negligence or willful
misconduct of the Landlord or any Landlord Parties), nor shall the Landlord or any Landlord Parties
be liable for any injury to the person of the Tenant or other persons in or about the Demised
Premises, (unless and only to the extent caused solely by the negligence or willful misconduct of
the respective Landlord Parties); the Tenant expressly agreeing to save the Landlord harmless in
all such cases and to carry public liability insurance in a company as provided in Section 6
hereof. Tenant covenants and agrees that it will not operate any machinery in the Demised Premises
which may cause unreasonable vibration or damage to the Demised Premises or unreasonably disturb or
annoy other tenants in neighboring buildings, nor to use a loud speaker or any other device nor
conduct any activity in or at the Demised Premises which can be heard outside the Building. No
storage of any kind will be allowed on the exterior of the Building, or on the Common Areas serving
the Building. 20. SUBORDINATION. Tenant further covenants and agrees that this Lease and the rights of Tenant hereunder are
subject and subordinate to the lien of any mortgage or deed of trust encumbrance or encumbrances
now or at any time hereafter placed upon said Demised Premises by Landlord, and to any and all
renewals, modifications, consolidations, recastings, refinancings and replacements thereof
(collectively or separately the Financing). It is the intention of the parties that this
provision be self-operating and that no further instrument shall be required to effect such
subordination. The Tenant, however, does hereby agree to execute and deliver to Landlord or its
mortgagees within ten (10) business days after each request any and all reasonable instruments
necessary to effect such subordination which the Landlord or its mortgagees may request or require.
Notwithstanding the subordination of this Lease as aforesaid, any present or future mortgagee or
beneficiary under any mortgage or deed of trust covering such Financing at its option may require
that this Lease shall be senior in lien to such mortgage or deed of trust, and that this Lease
shall not terminate in the event of foreclosure of any such mortgage or deed of trust. Tenant
covenants and agrees in the event of foreclosure of any such mortgage or deed of trust, within ten
(10) business days after request of the purchaser 27




---



##### 



or mortgagee, to attorn to the purchaser upon
such foreclosure sale and to recognize such purchaser as the landlord under this Lease (provided
such purchaser or mortgagee expressly recognizes Tenants occupancy and assumes Landlords
obligations to Tenant hereunder), and Tenant agrees to execute and deliver at any time, within ten
(10) business days after request of Landlord or of any such mortgagee any instrument which may be
necessary in any such foreclosure proceeding or otherwise to evidence such attornment. Tenant
further waives the provisions of any statute or rule of law, now or hereafter in effect, which may
give or purport to give Tenant any right or election to terminate or otherwise adversely affect
this Lease and the obligations of Tenant hereunder in the event of any such foreclosure. However,
provided Tenant is not in an Event of Default hereunder nor subject to any one (1) or more Events
of Bankruptcy, Landlord agrees to arrange for Landlords mortgagee to join with Tenant (and with
Landlord if the mortgagee so requires) in executing a non-disturbance, subordination and attornment
agreement in form and content satisfactory to the mortgagee, whereby such subordination of this
Lease to Landlords deeds of trust is confirmed but the mortgagee agrees that this Lease and
Tenants rights hereunder will not be terminated by a foreclosure by such mortgagee so long as
Tenant is not in an Event of Default under this Lease, and whereby Tenant grants the attornment
mentioned above. However, neither the refusal of any mortgagee to join in any such agreement nor
Landlords inability to cause same to be done shall in any respect affect this Lease or Landlords
rights or Tenants obligations hereunder. Any mortgagee or foreclosure purchaser or their
successors in interest shall not (a) be bound by any prepayment of Rent or other sums more than
thirty (30) days in advance paid by Tenant to any prior landlord (including Landlord), nor (b) be
bound by any amendment to this Lease or by any waiver or forbearance by any prior landlord
(including Landlord) made without prior written consent of such mortgagee, nor (c) be liable for
any act, omission or default of any prior landlord (including Landlord), nor (d) be subject to any
offsets or defenses Tenant may have against any prior landlord (including Landlord), nor (e) be
accountable hereunder for a Security Deposit posted by Tenant hereunder (except to the extent
received by such mortgagee or foreclosure purchaser, as the case may be). Any mortgagee of
Landlord shall be discharged of all obligations hereunder which may have arisen from its becoming a mortgagee in possession, and landlord, or otherwise after such
mortgagee disposes of its interest in the Demised Premises.  21.
    FIRE INSURANCE. Tenant will not carry on any activity in the Demised Premises, or do or permit anything to be
done therein, which is contrary to any law, ordinance, order or regulation of the federal, state,
county or municipal government, or of any board, agency or department thereof; and Tenant shall not
permit nor do anything which would increase the Basic Rate (as defined below) of the Landlords
fire insurance on the Building as established by the appropriate agency having jurisdiction. For
purposes of definition herein, the Basic Rate shall be such rate as published by the said
appropriate agency, exclusive, however, of any excess or surcharges appended thereon by virtue of
or directly attributable to so-called faults of management. If Tenants use or occupancy of or
business at the Demised Premises causes an increase in the final rate of Landlords insurance on
the Building or the Demised Premises over and above the Basic Rate for construction of this type
occupied for the purposes permitted hereunder, then Tenant, upon written notice from Landlord,
shall promptly take all necessary steps to eliminate the excess charge attributable to such faults
of management. Should Tenant refuse or fail to take 28




---



##### 



such action as may be necessary to eliminate
the cause for said excess charges, Tenant shall pay to Landlord, as Additional Rent within thirty
(30) days after written notice, that portion of the aforesaid fire and extended coverage insurance
premium caused by such excess charge on all outstanding insurance carried on the Demised Premises
and/or the Building of which same are a part.  22.
    PARKING AREAS. (A) Landlord shall provide free, on-site surface parking for the use in common of all tenants
in the Building at the rate of approximately THREE AND ONE-HALF (3.50)parking spaces per 1,000
square feet of rentable area in the Building. Landlord, at Tenants request, shall provide up to
twelve (12) reserved spaces at the main entrance to the Demised Premises for Tenants visitors and
designees. (B) Tenant further agrees to keep the parking area in front of the Demised Premises (between
the Building line and public property) clean and free of Tenants and its invitees merchandise,
property and equipment, at its own expense. In the event that Tenant shall fail to abide by the
foregoing provisions of this Lease, and it becomes necessary for Landlord to perform same, Tenant
agrees, after written notice from Landlord and an opportunity to cure, to reimburse the Landlord
for such reasonable expenses and costs occasioned by the Tenants neglect.  23.
    PLATE GLASS. Tenant agrees, at its own expense, to replace all plate glass doors, windows and partitions of
the Demised Premises with glass of like kind and quality if such glass is cracked, broken or
otherwise damaged by causes other than those insured against and covered by the insurance policies
carried on the Building (as referenced in Paragraph 8(B)).  24.
    NOTICES. All notices, demands or requests to be given under this Lease must be in writing, and sent via
certified or registered U.S. First Class Mail, return receipt requested, postage prepaid, or by
courier service, addressed if to Landlord at 9108 Gaither Road, Gaithersburg, Maryland, 20877, and
if to Tenant at the Demised Premises, or to such other address as either party itself may from time
to time designate to the other by like notice given at least ten (10) days before the date such
address change is effective. All such notices shall be deemed properly given if given as aforesaid
and deposited in a United States post office or mail box. The date of giving such notices shall be
deemed to be the second business day after the date of deposit thereof as aforesaid as concerns
mailed notices, or the date of receipt by the addressee or attempted delivery to the address in the
case of notices sent by courier.  25.
    TENANT ESTOPPEL CERTIFICATES; LANDLORD CURE RIGHTS; TENANT CURE RIGHTS. (A) TENANT ESTOPPEL CERTIFICATES. Tenant shall, without charge therefor, at any time
and from time to time, within ten (10) business days after request from 29




---



##### 



Landlord (but in no event more than two (2) times in any calendar year), execute, acknowledge and deliver to Landlord a
written estoppel certificate (in form and contents reasonably requested by Landlord), certifying,
to the best of Tenants actual knowledge, to Landlord and/or any mortgagee, assignee of a
mortgagee, any master landlord or any purchaser of the Building or Demised Premises, or any other
party designated by Landlord, as of the date of such estoppel certificate, as to all or such of the
following matters as reasonably requested by Landlord, to the extent such matters then are the case
(and if not, then stating all details to the contrary thereof), namely: (a) that Tenant has
accepted and is occupying the Demised Premises covered by this Lease; (b) that the Demised Premises
have been completed as required by the terms of this Lease; (c) that the Lease is in full force and
effect, and that no known Events of Default now exist thereunder; (d) that this Lease constitutes
the entire agreement between Landlord and Tenant and has not been modified; (e) that the Lease
Rents are now being paid on a current basis, and the date to which any Rent has been paid in
advance; (f) that Landlord has fulfilled all of its duties of an inducement nature, and neither
Landlord nor Tenant is in an Event of Default under the Lease; (g) that in the event the Tenant
receives written notice from Landlords mortgagee stating that a default has occurred under its
deed of trust loan, and that the mortgagee requires payment of rent to it, then the Tenant will
thereafter remit all Rent payments as directed and to the address set forth in such written notice;
(h) that there are no off-sets or credits against Rents, and Rents have not been prepaid more than
thirty (30) days in advance; (i) that Tenant has received no notice of a prior assignment, or
pledge of Rents, under this Lease; (j) details of any matters of which Tenant has knowledge or
which Tenant claims, which are contrary to the statements contained in clauses (a) through (f)
inclusive, (h) and (i) of this Paragraph; (k) the commencement and expiration dates of the then
operative term hereof, and of any then exercised renewal terms; (l) such other matters concerning
this Lease, the parties hereto and/or the Demised Premises as Landlord may reasonably request; and
(m) that Tenant understands such Estoppel Certificate is being relied on by the mortgage lender or purchaser requesting same as
an inducement to its loan or purchase. (B) LANDLORD CURE RIGHTS. Landlord shall not be deemed to be in default under any of
its obligations under this Lease unless (a) Tenant has given to Landlord (and to each of Landlords
mortgagees of whom Tenant has been given written notice of such mortgagees name and address)
written notice of such Landlord default, and (b) such default of Landlord has not been cured by
Landlord or its mortgagee within thirty (30) days after their receipt of such notice or within such
additional time as may reasonably be necessary to cure same if Landlord or its mortgagee acts with
commercially reasonable diligence to cure same (provided, that such mortgagee shall have such
additional time to cure same as may be necessary to enable it to exercise any rights under its deed
of trust and other loan documents, including foreclosure and acquisition of control and/or
possession of the Demised Premises and Building). The cure periods aforesaid afforded Landlord and
its mortgagees shall be further extended by all delays in such cure actions caused by fire or other
casualty, strikes, lockouts or other labor troubles, shortages of equipment, materials or
utilities, power outages, acts of God or the public enemy, vandalism, governmental requirements,
action or inaction or other causes not reasonably within their control. Tenant shall not be
entitled to exercise any legal, equitable or other remedies for any default of Landlord unless same
remains uncured beyond the grace period after receipt of written notice as aforesaid. Landlord
shall not be deemed in default under this Lease, if Landlord or its mortgagee(s) cure(s) such
default within the applicable grace period after 30

##### 



notice as aforesaid. Tenants rights and remedies
with respect to any default of Landlord hereunder shall be subject to the terms and provisions of
this Lease, and in no event shall include any right of Tenant to self-help or to perform any work
on behalf of Landlord (except as specifically provided herein), nor any right of Tenant to withhold
or to any abatement or setoff with respect to any Rent or other sums payable by Tenant under this
Lease, nor any right to terminate this Lease. (C) TENANT CURE RIGHTS. Notwithstanding the foregoing, if Landlord shall fail to
perform any of its covenants or agreements contained in this Lease which materially and adversely
affect Tenants occupation and use of the Premises, and Landlord shall fail to commence to cure
(and diligently prosecute) such default within ten (10) days after receipt of written notice of
default from Tenant (in which notice Tenant shall specify in detail the nature and extent of the
alleged default, and the proposed means by which to cure same), Tenant may, in addition to all
other remedies now or hereafter afforded or provided by law, perform such covenant or agreement on
behalf of Landlord in accordance with all applicable Laws, or otherwise cure any such default, and

(M) BINDING EFFECT. The provisions of this Lease shall bind, and inure to the
benefit of, the parties hereto and their respective heirs, executors, administrators, personal
representatives, successors and (subject to Section 7 hereof) assigns. (N) GENDERS; PRONOUNS. Wherever required in the context, the singular number shall

gender shall be deemed to include all genders. It is understood and agreed that the relationship
between Landlord and Tenant created by this Lease is that of landlord and tenant only and no other
and they shall not be deemed partners or agents of the other party hereto. 29. RENEWAL OPTION. (A) OPTIONS. Provided that no Event of Default of Tenant exists under this Lease at
the time of exercise of any of these renewal options, or at time of commencement of any of the
renewal terms, the Tenant shall have the right and option to renew and extend the term of this
Lease for two (2) additional, consecutive periods of FIVE (5)years each (each a Renewal Term),
commencing therefor at 12:01 a.m. on the day immediately following the expiration date of the
Initial Term or of the immediately expired prior Renewal Term, as the case may be. Each such
renewal option may be exercised only by written notice from Tenant to Landlord given at least two
hundred seventy (270) days prior to the expiration of the then current term hereof. Such renewal
shall be upon the same terms and conditions of this Lease, except that Tenant shall be limited to
said two Renewal Terms, and Landlord shall not be obligated to perform any work described in
Paragraph 2(B) hereof or any other work for the Demised Premises during or with respect to the Renewal Terms. If Tenant fails to exercise the first renewal option provided
herein, then both renewal options shall automatically be null and void. These renewal options
shall not be assignable by Tenant without Landlords prior written consent in each case (except as
provided in Section 7 above). The renewal options shall apply only with respect to all space
leased by Tenant under this Lease. (B) RENEWAL RENT. Basic Annual Rental during the Renewal Terms shall be at
NINETY-FIVE PERCENT (95%) of the prevailing rate (including also annual increases, other additional
charges, and market concessions) as reasonably determined by Landlord and Tenant for other similar
space in the Germantown and Gaithersburg sub-markets (the Renewal Rental). Notwithstanding the
foregoing, the Renewal Rental payable by Tenant for the first lease year of the first Renewal Term
shall not be less than the Basic Annual Rental payable by Tenant during the seventh
(7th) Lease Year of the Initial Term. The Renewal Rental payable by Tenant for the
first Lease Year of the second Renewal Term shall not be less than the Basic Annual Rental payable
by Tenant for the third (3rd) Lease Year of the first Renewal Term. If the rent floor
described above is applicable to the First Renewal Term, Landlord shall provide to Tenant a
refurbishment allowance equal to Seven Dollars ($7.00) per square foot of rentable space in the
Demised Premises. No refurbishment allowance shall be provided by Landlord to Tenant if the rent
floor is applicable to the second Renewal Term. Furthermore, the Basic Annual Rental payable by
Tenant during the first Lease Year of each Renewal Term shall be subject to escalation, commencing
with the second and each succeeding Lease Year during the applicable Renewal Term, at the
prevailing rate in the above-specified sub-markets, which rate shall not be less than two percent
(2%) per year. Landlord shall notify Tenant as to the Renewal 33

##### 



Rental within ten (10) business days after request by Tenant for such information, which request shall be made by Tenant not earlier
than three hundred (300) days before the end of the then current Term. Basic Annual Rental shall
be payable during the Renewal Terms in the manner as prescribed in this Lease. In addition to the
Renewal Rental, Tenant shall pay to Landlord, at the times indicated herein, the Additional Rent
and other sums required to be paid by Tenant pursuant to the terms of this Lease. 30. REMOVAL BY TENANT. By the expiration of the Initial Term (or any duly exercised renewal term, as the case may
be), or any termination of this Lease, Tenant shall have removed from the Demised Premises all of
Tenants and its assignees and subtenants merchandise, furniture and other personal property
(excluding any items which belong to Landlord or which are not to be removed by Tenant, as
elsewhere provided), and Tenant at its own expense will promptly repair any damage done to the
Demised Premises or the Building of which same are a part by installation or use thereof or by any
such removal, reasonable wear and tear and damage by casualty and condemnation excepted. Any of
Tenants property not removed by the expiration or termination of this Lease shall, at Landlords
option, be deemed abandoned and may be retained, disposed of or otherwise dealt with by Landlord as
it deems fit (and all at the risk, cost and expense of Tenant). 31. LIEN ON TENANTS PROPERTY. Landlords lien for Rent upon all of the goods, wares, chattels, fixtures, furniture and other
personal property of Tenant which may be in or upon the Demised Premises during the term of this
Lease or any renewal, extension or holdover term shall be subordinated to the rights of a lender
who acquires a security interest in the property of the Tenant in accordance with the Landlords
Consent & Waiver, the form of which is attached hereto as Exhibit E and made a part
hereof. However, Landlord will at all times retain ownership of and all rights to the leasehold
improvements without subordination to a Tenant lender. Notwithstanding anything to the contrary
contained herein, Landlord agrees that the following personal property of Tenant is expressly
exempt from Landlords lien as set forth in this Section 31, and that at no time shall Landlord
have any claim or rights with respect thereto: all scientific instrumentation designed, modified
or adapted by Tenant, computers, routers, storage devices and servers used in Tenants business and
research, all data generated by or created for Tenant, all software developed or adapted by or for
Tenant, all databases to which Tenant has contributed data or had data contributed on its behalf,
all biological samples held by Tenant, all intellectual property related to any of the foregoing
(whether or not patented or patentable) together with all patent rights and other intellectual
property rights therein and any other such proprietary thing as may pertain to Tenants business,
research, design, development activities or its collaborators, clients or Tenant affiliates. 32. BROKERAGE. Landlord and Tenant recognize Scheer Partners Inc. and Manekin, LLC(the Brokers) as the
sole real estate brokers in connection with this Lease. Landlord agrees to pay 34

Landlord and Brokers. Tenant and Landlord represent and warrant that it has not engaged or dealt
with any other real estate broker or agent in connection with this Lease other than the Brokers.
Tenant and Landlord agree to indemnify, defend and hold each other harmless from any commission or
other related claims, including court costs and reasonable attorneys fees, which Landlord may
suffer, incur or be made a party to as a result of any misrepresentation by Tenant regarding other
brokers used in connection with this Lease. 33. RULES AND REGULATIONS. Tenant and its Permittees shall at all times abide by the Rules and Regulations attached
hereto as Exhibit B and made a part hereof. In addition, Tenant and its Permittees shall
abide by such other reasonable rules and regulations for the operation and maintenance of the
Building as may be promulgated from time to time by Landlord to all tenants in the Building, with a
copy sent to Tenant not less than thirty (30) days prior to the effective date of any such
amendments, provided, however, that the same are necessary in Landlords reasonable judgment for
the general well being, safety, care and/or for the cleanliness of the Building or its
appurtenances, and that the same apply to all tenants of office, laboratory or warehouse space in
the Building similar to the Demised Premises. Landlord shall enforce such Rules and Regulations against all tenants in a fair and equitable manner. Landlord shall not be liable
to Tenant for violations of the same by any other tenant or its Permittees. Landlord will use
reasonable efforts to cause other tenants in the Building to cease having any excessive noise or
noxious fumes emanating outside their space which unreasonably disturb Tenant, but Landlord will
not be liable therefor nor shall this Lease be affected thereby. If there is any inconsistency
between this Lease and said Rules and Regulations, this Lease shall govern. 34. ENVIRONMENTAL HAZARDS. (A) In the conduct of its business at the Demised Premises, Tenant covenants and agrees at
its own expense to comply with all Environmental Laws (as hereinafter defined) applicable to the

placement of all cabling and wiring ancillary thereto, all of which Landlord approvals shall not be
unreasonably withheld, conditioned or delayed. Landlord makes no representation concerning the

approval of Tenants plans and specifications shall in no event be construed as constituting such a
representation. Tenant shall be responsible, at its own expense, for obtaining and maintaining in
full force and effect all approvals, permits and licenses required by any federal, state or local
government for installation and operation of the Tenants Equipment and for paying all fees attendant thereto and for complying with all other Laws relating to the

have exercised those rights prior to the exercise thereof by Tenant hereunder. Any such similar
rights granted to any other tenant shall similarly restrict such other tenants equipment from
interfering with Tenants Equipment, and Landlord shall enforce all such restrictions. If Tenant
ceases at any time to be the sole Tenant of the Building, Tenant shall be responsible for and
promptly shall correct and pay for any damage to or interference with the operation of the Tenants
Equipment by any third party. Landlord shall have the right to require Tenant to relocate the
Tenants Equipment at Landlords cost to another suitable location on the rooftop reasonably

EXHIBIT E LANDLORDS CONSENT AND WAIVER THIS LANDLORDS CONSENT AND WAIVER made as of this  day of , 2000, between
Westphalia Center II Limited Partnership, a Maryland limited partnership, with its principal place
of business at 9108 Gaither Road, Gaithersburg, Maryland 20877(the Landlord), and
, a corporation (Lender), and Large Scale Proteomics Corporation,
a Delaware corporation (Tenant). WITNESSETH: WHEREAS, Landlord is the owner of certain real estate known by street address as Seneca
Meadows Corporate Center, 20439, 20441, 20443, 20445, 20447, 20449 and 20451 Goldenrod Lane
(Germantown, Montgomery County, Maryland(hereinafter called Premises); and WHEREAS, Landlord has leased the Premises pursuant to the terms of a certain lease dated
, (the Lease) to Tenant; and WHEREAS, contemporaneously herewith, the Tenant and the Lender have entered into certain
financing transactions and in connection therewith the Tenant has granted to the Lender a security
interest in that part of the Tenants presently owned and hereafter-acquired accounts receivable,
inventory as set forth in Exhibit A attached hereto and made a part hereof and proceeds thereof
(Collateral) pursuant to that certain Loan and Security Agreement dated 
(Agreement) between Tenant and Lender; and WHEREAS, as a condition of said financing transactions, the Lender has required Tenant to
obtain from the Landlord this Landlords Consent and Waiver. NOW, THEREFORE, in consideration of the foregoing and for other good and valuable
consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows: 1. To the best of Landlords and Tenants knowledge, the Lease is in full force and effect, is
binding upon the parties thereto in accordance with its terms and no event has occurred which, with
the passage of time or upon notice or both would give rise to the Landlords right to terminate the
Lease. However, nothing contained herein shall waive any rights of Landlord or obligations of
Tenant with respect to any defaults of Tenant under the Lease of which Landlord may become aware. 2. The Tenant and Lender hereby inform Landlord of the existence of, and Landlord hereby
acknowledges being so informed of the Tenants grant of a security interest to the Lender in the
Collateral, and consents thereto. However, nothing herein contained shall impose upon Landlord any
liability for any payments or performance under the Agreement or 52

with respect to any loans made by Lender to Tenant or under any documents now or hereafter
evidencing or securing such financing. 3. The Landlord hereby subordinates in favor of the Lender to the extent only of the
outstanding Obligations (as defined in the Agreement) from time to time owed by Tenant to Lender
pursuant to the Agreement, any lien, claim or interest, including but not limited to any Landlords
lien or right to distress for rent, which the Landlord may have or may hereafter acquire as to the
Collateral whether presently located at the Premises or hereafter to be located at the Premises.
In the event of a default of Tenant under the Agreement, or in the event Landlord terminates the
Lease by reason of default of Tenant thereunder, then in either such event Lender shall, subject to
Lenders recourse under law and upon giving Landlord at least 24 hours prior written notice, have
the right to enter the Premises and to remove the Collateral therefrom (but only if the Collateral
is then located in the Premises), provided that Lender shall do so at its own expense and shall
complete such removal within thirty (30) days after the termination of the Lease, and Lender shall
promptly repair at its own expense all damage to the Premises and to any property of Landlord or
others caused by such removal. Any such Collateral not removed from the Premises within said
thirty (30) days may be removed by Landlord and stored or disposed of, at the risk, cost and
expense of Tenant and without liability upon Landlord for any damage or loss thereof. Nothing
herein contained shall impose upon Landlord any liability or obligation to see to the safety,
security, repair or protection of the Collateral, nor for any loss thereof or damage thereto. 4. If Landlord terminates the Lease and recovers possession of the Premises, then the Lender
and Tenant agree that Landlord, at its option and exclusive discretion, shall have the right (but
not the obligation) to relocate and consolidate any or all of Tenants personal property forming
part of the Collateral to one or more locations within the Premises as determined by Landlord (the
Storage Area), at the risk and expense of Tenant and with no liability upon Landlord for any
damage to or loss of any such Collateral. At all times from and after any termination of the Lease
and recovery of possession of the Premises as a result of Tenants default (and subject to Lenders
rights hereunder applicable during the thirty (30) days mentioned in Paragraph 3), Landlord shall
have the right to offer for leasing and to lease the Premises in whole or part to any one or more
tenants, and to show the Premises to such prospective or new tenants, and Tenant and Lender shall
not interfere with any such actions taken by Landlord. Landlords rights under this paragraph
shall not limit any of its other rights and remedies under the Lease in any circumstances
whatsoever. 5. During the period commencing on the date Landlord terminates the Lease and recovers
possession of the Premises as a result of Tenants default and ending on the date (the Termination
Date) which is the earlier to occur of (a) the date Lender and/or Tenant have removed all of the
Collateral from the Premises, or (b) the 30th day after the date Landlord so terminates the Lease
and recovers possession of the Premises, Landlord will permit the Lender to enter the Storage Area
in which the Collateral is located, solely for the purpose of removing and/or selling the
Collateral at the sole risk, cost and expense of the Lender and at no liability or expense to the
Landlord. Lender shall at its own expense repair any damage to the Premises caused by any acts,
omissions or negligence of Lender, its agents, invitees, employees or contractors (Lender
Faults), and Lender shall indemnify, defend and hold Landlord harmless from all loss, costs,
damage, litigation, reasonable attorneys fees and claims arising out of any 53

##### 



such Lender Faults. Any of the Collateral remaining in the Premises after the Termination
Date may be removed, stored, disposed of or otherwise dealt with by Landlord at the risk, cost and
expense of Tenant and without liability upon Landlord for any loss or damage to such Collateral. 6. During all periods of time while the Lender and/or its agents, employees or contractors
(Lender Parties) are using the Storage Area or any portion thereof for the purposes authorized
and described in paragraph 5 above, or while Lender or any Lender Parties are using any of the
Premises pursuant to Paragraph 3, the Lender shall pay to Landlord per diem rent for such Storage
Area or Premises so used (calculated on a monthly basis by multiplying the monthly rental including
pass-throughs for real estate taxes, insurance and common area charges payable by Tenant for the
last full calendar month of the Lease in which such monthly rental was payable prior to termination
of the Lease); such per diem rent to be paid in an amount equal to 1/30th of such monthly rental
and other sums for each day that the Lender Parties are making use of such Storage Area or of any
other part of the Premises as aforesaid. Such rental payments shall be made by Lender to Landlord
within five (5) days after each request of Landlord; such request to be made not more often than
once every seven (7) days. Said per diem rental payments shall be calculated without regard to any
rental abatement provisions of the Lease. 7. The Landlord further agrees that the Collateral shall at all times be deemed personal
property and not real property or in any way part of the Premises. Landlord will endeavor to give
to Lender written notice of any default of Tenant under the Lease which would entitle Landlord to
terminate the Lease, or of any termination of the Lease by Landlord, provided that Landlord shall
incur no liability to Lender or to Tenant or to their successors or assigns if Landlord fails to
give any such notice. Notwithstanding the foregoing, in no event shall the Collateral be deemed to
include any property which is permanently affixed to the Premises, including but not limited to any
mechanical, electrical or plumbing equipment necessary for the operation of and forming part of
said Premises, by whomsoever installed therein. 8. All notices, demands, requests, or other communications which may be or are required to be
given, served, or sent by any party to any other party pursuant to this Agreement shall be in
writing and shall be mailed by first-class, registered or certified mail, return receipt requested,
