2.   Demise. Landlord hereby leases unto Tenant, and Tenant does hereby rent
from Landlord the Premises. In addition thereto, Tenant shall have the right to
use, on a non-exclusive basis, and in common with the other tenants of the
Building the Common Areas of the Building (as that term is defined in Section
6.2.4 hereof).
 
3.  Term.
 
3.1 Commencement Date and Term. This Lease shall commence on the "Initial
Premises Commencement Date" (as herein defined) and shall be for the Initial
Term, plus the portion of a calendar month, if any, from the Commencement Date
to the last day of the calendar month in which such Commencement Date occurs. As
used in this Lease, the term "Initial Premises Commencement Date", as advanced
or postponed pursuant to the terms hereof, shall be defined as the earlier to
occur of (a) the date on which Tenant takes possession and occupancy of the
Initial Premises, or (b) the date which is fifteen (15) days following that date
which is the first on which all of the following events have occurred, namely
(i) the Initial Premises is "substantially completed", as defined in Section 3.2
following, (ii) Landlord has given Tenant written notice that the Initial
Premises is "substantially completed", and (iii) the "Target Date" as defined in
Section 3.2 has arrived. Within fifteen (15) days after request from Landlord,
Tenant shall execute and deliver the Commencement Date Agreement in
substantially the form attached hereto as Exhibit "G". As used in this Lease,
the term "Remaining Premises Commencement Date" shall mean that day immediately
following the expiration or sooner termination of the Sublease between MWH
Americas, Inc. dated May 31, 2005 for the Remaining Premises, provided MWH
Americas, Inc. does not elect to extend the term of the lease for the Remaining
 
Premises.
 
3.2 Substantial Completion. Subject to the provisions of Section 35, Landlord
shall use its reasonable efforts to "substantially complete" the Initial
Premises by the Target Date, provided that the Target Date shall be extended for
the number of days that Tenant fails to satisfy its obligations under Section
35. "Substantially complete" means that: (i) the construction of the
improvements described in Section 35 has been completed so that Tenant can use
the Initial Premises for its intended purposes without material interference to
Tenant conducting its ordinary business activities, (ii) the Initial Premises
has been approved for occupancy by governmental authorities having jurisdiction,
(iii) Tenant has ready access to the Building and Initial Premises through the
lobby, hallways and elevators, and (iv) the Initial Premises is ready for
installation of any equipment, furniture, fixtures or decoration that Tenant
will install. Landlord shall keep Tenant advised as to its progress with regard
to "substantially completing" the Initial Premises by the Target Date.
Notwithstanding the foregoing, the requirements of subsection (ii) shall be
deemed satisfied if all of the other subsections have been satisfied and the
government approval is delayed as a result of the installation of furniture,
fixtures or equipment which is not included within the scope of Landlord's
responsibilities under Section 35 below.
 
3.3 Option to Extend Lease Term. Provided Tenant is not in default of any term,
covenant or condition of this Lease, Tenant shall have the option to extend the
Initial Term of this Lease for one (1) additional period of three (3) years (the
"Renewal Term") to commence immediately upon the expiration of the Initial Term.
 
Tenant's rental of the Premises during the Renewal Term shall be upon the same
terms, covenants and conditions contained in this Lease, except that Tenant
shall pay to Landlord as Base Rent that amount equal to the "Prevailing Market
Rate" for the Premises for the Renewal Term as hereinafter defined (including
annual adjustments). For purposes of this Section 3.3, the term "Prevailing
Market Rate" shall mean the then prevailing market rate being charged for
comparable space in comparable office buildings within a ten (10) mile radius of
the Premises, with consideration given for construction allowances, commissions,
free rent, and other concessions or premiums. In order to exercise its option
granted herein, Tenant shall notify Landlord in writing of its intent to renew
not less than one hundred eighty (180)days prior to the expiration of the
Initial Term. Within thirty (30) days following the exercise by Tenant of its
option to extend the Lease for the Renewal Term, Landlord shall notify Tenant in
writing of its determination of the Prevailing Market Rate for the Renewal Term
as reasonably determined by Landlord ("Landlord's Notice"). Within ten (10) days
after receipt of Landlord's Notice, Tenant shall notify Landlord in writing of
Tenant's acceptance or rejection of such rate. If Tenant shall accept such
Prevailing Market Rate, Landlord and Tenant shall enter into an amendment to
this Lease acknowledging such renewal and setting forth any terms at variance
with the terms of this Lease. If within the ten (10) day period, Tenant shall
reject such Prevailing Market Rate as determined by Landlord for the Renewal
Term, then within twenty (20) days thereafter, Landlord and Tenant shall meet at
a mutually acceptable time and place and shall use their reasonable efforts to
agree upon the Prevailing Market Rate. If Landlord and Tenant shall fail to
agree upon such Prevailing Market Rate within the twenty (20) day period,
Landlord and Tenant shall each appoint an independent commercial leasing broker
licensed in the Maryland area within the next ten (10) days (the "Brokers").
Such Brokers shall deliver their respective estimates of the Prevailing Market
Rate within ten (10) days after being appointed. If the estimates of the
Prevailing Market Rate as quoted by the Brokers are within ten percent (10%) of
each other, the Prevailing Market Rate shall be deemed to be the average of the
estimates presented by the Brokers. If the estimates of the Prevailing Market
Rate as quoted by the Brokers differ by more than ten percent (10%), then
Landlord and Tenant shall jointly appoint a third independent commercial leasing
broker licensed in the Maryland area within ten (10) days after the receipt of
the initial brokers' estimates (the "Third Broker") who shall deliver its
estimate of the Prevailing Market Rate within ten (10) days after being
appointed and such estimate shall be deemed to be the Prevailing Market Rate.
Tenant shall notify Landlord within ten (10) days after receipt of the estimate
of the Prevailing Market Rate (whether as resulting from the average of the
Brokers or from the Third Broker, as applicable), whether Tenant shall accept
such Prevailing Market Rate, whereupon Landlord and Tenant shall enter into an
amendment to this Lease acknowledging such renewal and setting forth any terms
at variance with the terms of this Lease. If (i) Tenant shall fail to respond to
Landlord's Notice as provided above, (ii) Tenant shall fail to deliver the
requisite notice exercising its option to extend by the date prescribed above,
(iii) Tenant does not respond within ten (10) days following receipt of
Landlord's Notice or (iv) Tenant does not accept the Prevailing Market Rate
within ten (10) days following Landlord's notification of the Prevailing Market
Rate, as determined either by the average of the Brokers or from the Third
Broker, as applicable, then Tenant's option to extend this Lease for the Renewal
Term shall be void and inoperable. Landlord and Tenant shall each pay the fee of
the broker designated by them originally and shall split the fees of the Third
Broker.
 
3.4 Definition of "Term". As used herein, the word "Term" shall refer to the
Initial Term and the Renewal Term, if applicable.
 
4.  Security Deposit and Advance Rent.
 
4.1 Security Deposit. Tenant has this day paid to Landlord the Security Deposit
to be held by Landlord as security for the performance by Tenant of all
obligations imposed on Tenant hereunder. If Tenant shall perform all such
obligations, the Security Deposit shall be refunded to Tenant, without interest,
at the end of the Term. If Tenant shall default in any such obligation, Landlord
shall be entitled to apply the Security Deposit, pro tanto, toward Landlord's
damages and Tenant shall replenish the Security Deposit to the full amount
within ten (10) days after receipt of a written notice from Landlord which sets
forth the amount to be replenished. If the Security Deposit is not fully
restored, it shall constitute an Event of Default (as defined in Section 21)
under the terms of this Lease, and Landlord shall have the benefit of all
remedies permitted pursuant to the terms of this Lease and the laws of the State
of Maryland.
 
4.2 Advance Rent. Upon execution of this Lease, Tenant shall pay Landlord the
Advance Rent to be held as advance rent and security and which Landlord shall be
entitled to retain, without limitation of other remedies, for any defaults of
this Lease by Tenant occurring prior to the commencement of the Term. If no such
defaults occur, the Advance Rent shall be applied by Landlord against first
installments of Base Rent payable by Tenant hereunder.
 
5.   Use. Tenant shall use and occupy the Premises continuously during the Term
of this Lease solely for general office purposes in accordance with applicable
zoning regulations and for no other purpose. Tenant acknowledges that (a)
violation of the foregoing continuous occupancy and use covenant shall be a
material breach of this Lease, and (b) Landlord considers such continuous use
and occupancy covenant a valuable contractual interest with which no other
landlord should interfere by attempting to induce Tenant to move to another
building. Tenant recognizes that its occupancy of the Premises continuously
throughout the Term of this Lease provides Landlord a significant benefit in the
perception of the Building by other prospective tenants who will negotiate with
Landlord for space in the Building in the future as well as the perception of
other existing tenants who will be negotiating with Landlord to renew their
leases and remain in the Building.
 
6. Rent.
 
6.1 Base Rent. Commencing on the Initial Premises Commencement Date, as rent for
the Initial Premises during each year of the Term, Tenant shall pay to Landlord
an Annual Base Rent, in equal monthly installments, in advance on the first day
of each calendar month during the Term, and without deduction, setoff or demand
in accordance with the schedule set forth in Section 1.1.8.A above. Commencing
on the Remaining Premises Commencement Date, as rent for the Remaining Premises
during each year of the Term, Tenant shall pay to Landlord an Annual Base Rent,
in equal monthly installments, in advance on the first day of each calendar
month during the Term, and without deduction, setoff or demand in accordance
with the schedule set forth in Section 1.1.8.B above. In addition to the Base
Rent, if the Term for the Initial Premises should commence on or if the
Remaining Premises Commencement Date should fall on a day other than the first
day of a calendar month, Tenant shall pay to Landlord upon the Initial Premises
Commencement Date or the Remaining Premises Commencement Date, as thecase may
be, a sum equaling that percentage of the applicable monthly rent installment
which equals the percentage of such calendar month falling within the Term.
 
6.2 Definitions. For the purposes hereof, the following definitions shall apply:
 
6.2.1 "Property" shall mean the Building, the land upon which same is situated
and all fixtures and equipment thereon or therein, all commonly owned or shared
appurtenances,
including but not limited to, parking areas, walkways, landscaping and
utilities, whether located on the land upon which the Building is situated or
elsewhere.
 
6.2.2 "Building Expenses" shall be all those expenses paid or incurred by
Landlord in connection with the owning, maintaining, operating and repairing of
the Property or
any part thereof, in a manner deemed reasonable and appropriate by Landlord and
shall include, without limitation, the following:
 
6.2.2.1 All costs and expenses of operating, repairing, lighting, cleaning, and

compensation insurance covering personnel) the Property or any part thereof, as
well as all costs incurred in removing snow, ice and debris therefrom and of
policing and regulating traffic with respect thereto, and depreciation of all
machinery and equipment used therein or thereon,

savings devices;
 
6.2.2.3 Maintenance and repair of mechanical and electrical equipment including

6.2.2.6 Repainting and redecoration of all Common Areas;
 
6.2.2.7 Repair and maintenance of the parking areas, including without

6.2.2.9 Management fees, wages, salaries and compensation of all persons engaged
in the maintenance, operation or repair of the Property and the provision of
amenities to
all tenants in the Property (including Landlord's share of all payroll taxes)
but only to the extent they are so engaged;
 
6.2.2.10 Legal, accounting and engineering fees and expenses, except for
those related to disputes with tenants or which are a result of andlor are based
on Landlord's negligence or other tortious conduct;
 
6.2.2.11 Costs and expenses that may result from compliance with any
governmental laws or regulations that were not applicable to the Common Areas at
the time same were originally constructed; and
 
6.2.2.12 All other expenses which under generally accepted accountingprinciples
would be considered as an expense of maintaining, operating, or repairing the
Property. Notwithstanding the foregoing, all expenses (whether or not such
expenses are enumerated on items 1 through 11 of this Section 6.2.2) which would
be considered capital in nature under generally accepted accounting principles
shall be excluded from "Building
 
Expenses" unless same are amortized in accordance with generally accepted
accounting principles.
 
6.2.3 "Taxes" shall mean all real property taxes including currently due
installments of assessments, sewer rents, ad valorem charges, water rates, rents
and charges, front foot benefit charges, and all other governmental impositions
in the nature of any of the foregoing in connection with the Project. Excluded
from Taxes are (i) federal, state or local income taxes, (ii) franchise, gift,
transfer, excise, capital stock, estate or inheritance taxes, and (iii)
penalties or interest charged for late payment of Taxes. If at any time during
the Term the method of taxation prevailing at the commencement of the Term shall
be altered so as to cause the whole or any part of the items listed in the first
sentence of this subparagraph to be levied, assessed or imposed, wholly or
partly as a capital levy, or otherwise, on the rents received from the Project,
wholly or partly in lieu of imposition of or in addition to the increase of
taxes in the nature of real estate taxes issued against the Project, then the
charge to Landlord resulting from such altered additional method of taxation
shall be deemed to be within the definition of "Taxes." Tenant acknowledges and
agrees that the Project is located on a single lot and the real property taxes
pertain to the entire Project and are not limited to the Building or the
Property.
 
6.2.4 "Common Areas" shall mean those areas and facilities which may be from
time to time furnished to the Building by Landlord for the non-exclusive general
common use of tenants and other occupants of the Building, their officers,
employees, and invitees, including (without limitation) the hallways, stairs,
parking facilities, washrooms, and elevators.
 
6.2.5 "Lease Year" shall mean the first twelve (12) month period following the
Commencement Date and each succeeding twelve (12) month period thereafter up to
the end of the Term; provided, however, that if the Commencement Date shall
occur on a day other than the first day of a calendar month, then the first
Lease Year shall include that portion of a calendar
 
month in which the Commencement Date occurs in addition to the first twelve (12)
month period.
 
6.2.6 "Rentable Area of the Project" shall have the mean the rentable area of
any improvements in the Project as of the date that Tenant is required to make
any payments hereunder. Landlord and Tenant shall enter into a written amendment
to this Lease which
memorializes the Rentable Area of the Project when any additional improvements
are completed in the Project.

 
6.3 Rent Adjustments for Taxes.
 
6.3.1 Commencing with the third Lease Year, on or before April 30 of each Lease
Year, Landlord shall total the Taxes and shall allocate such Taxes to the
Rentable Area of the Building in the following manner: Taxes for the foregoing
calendar year shall be totaled and such total shall be divided by the total
rentable square feet in the Project thereby deriving the "Cost of Taxes Per
Square Foot" of rentable area.
 
6.3.2 In the event that the Cost of Taxes Per Square Foot assessed for any
calendar year which is wholly or partly within the Term are greater than the
Base Year Taxes, Tenant shall pay to Landlord, as additional rent at the time
such Taxes are due and payable, the amount of such excess times of Rentable Area
of the Premises. Any additional rent due Landlord under this Section shall be
due and payable within thirty (30) days after Landlord shall have submitted a
written statement to Tenant showing the amount due. For Tenant's obligation for
such additional rent at the beginning or end of the Lease, see Section 6.5.
Landlord may, in its discretion, make a reasonable estimate of such additional
rent with respect to Taxes, and require Tenant to pay each month during such
year 1/12 of such amount, at the time of payment of monthly installments of Base
Rent. In such event, Tenant shall pay, or Landlord shall refund or credit to
Tenant's account, any underpayment or overpayment of such additional rent within
thirty (30) days of Landlord's annual written statement of Taxes due. Tenant
shall have the right to examine, at Tenant's sole expense, Landlord's records
with respect to any such increases in additional rent; provided, however, that
unless Tenant shall have given Landlord written notice of exception to any such
statement within sixty (60) days after delivery thereof, the same shall be
conclusive and binding on Tenant. No credit shall be given to Tenant if the cost
of Taxes Per Square Foot are less than the Base Year Taxes.
 
All reasonable expenses incurred by Landlord (including attorneys', appraisers'
and consultants' fees, and other costs) in contesting any increase in Taxes or
any increase in the assessment of the Project shall be included as an item of
Taxes for the purpose of computing additional rent due hereunder.
 
6.4 Rent Adjustments for Building Expenses.
 
6.4.1 Commencing with the third Lease Year, on or before April 30 of each Lease
Year, Landlord shall compute the Building Expenses for the prior Lease Year and
shall allocate such costs to the Rentable Area of the Building in the following
manner: Building Expenses shall be totaled and such total shall be divided by
the total Rentable Area of the Building thereby de-riving the "Cost of Building
Expenses Per Square Foot" of rentable area. If Landlord incurs an extraordinary,
uncontrollable expense during the Base Year to determine Building Expenses
(e.g., excessive snow or blizzard), such extraordinary expenses shall not be
included in the computation of Base Year Building Expenses, but such item shall
be included in Base Year Building Expenses in an amount equal to the average
amount of ordinary expenses for such item by averaging the three (3) prior
years' expenses for such item.
 
6.4.2 In the event that the Cost of Building Expenses Per Square Foot of
rentable area for any year which is wholly or partly within the Term are greater
than the Base Year Building Expenses, Tenant shall pay to Landlord, as
additional rent, the amount of such excess times the number of square feet of
Rentable Area of the Premises, as set forth in Section 1 above. Any such
additional rent shall be due within thirty (30) days after Landlord has
submitted a written statement to Tenant showing the amount due. Landlord may, in
its discretion, make a reasonable estimate of such additional rent with respect
to any calendar year, and require Tenant to pay each month during such year 1/12
of such amount, at the time of payment of monthly installments of Base Rent. In
such event, Tenant shall pay, or Landlord shall refund or credit to Tenant's
account, any underpayment or overpayment of such additional rent within thirty
(30) days after Landlord has submitted a written statement of actual Building
Expenses for the calendar year. Tenant, at Tenant's sole expense, shall have the
right to examine Landlord's records with respect to any such increases in
additional rent; provided, however, that unless Tenant shall have given Landlord
written notice of exception to any such statement within sixty (60) days after
delivery thereof, the same shall be conclusive and binding on Tenant. No credit
shall be given to Tenant if the cost of Building Expenses Per Square Foot are
less than the Base Year Building Expenses. Notwithstanding anything to the
contrary contained herein, Landlord shall use diligent efforts to keep Building
Expenses at reasonable amounts, while maintaining the Building as a first class
office building. Tenant acknowledges that with regard to certain Building
Expenses, some tenants may be paying various fees directly to the service
provider (including, without limitation, janitorial services and electricity
charges), in which event the computation of Cost of Building Expenses Per Square
Foot for such items shall be determined by using the total rentable square
footage of the Building reduced by the rentable square footage of the tenants
who are paying such fees directly to the service provider. If occupancy of the
Building during any calendar year, including the Base Year for Building
Expenses, is less than ninety-five percent (95%), then Building Expenses for
that calendar year shall be "grossed up" to that amount of Building Expenses
that, using reasonable projections, would normally be expected to be incurred
during the calendar year in question if the Building was ninety-five percent
(95%) occupied during the applicable calendar year period, as determined under
generally accepted accounting principles; it being understood that the written
statement submitted to Tenant shall provide a reasonably detailed description of
how the Building Expenses were grossed up and that only those component expenses
that are affected by variations in occupancy levels shall be grossed up. Such
additional rent shall be computed on a year-to-year basis.
 
Landlord shall use its reasonable efforts to obtain separate invoices for
Building Expense items which pertain to each of the buildings comprising the
Project, as compared to the entire Project. Notwithstanding anything herein to
the contrary, if for any reason, Landlord is not able to obtain a separate
invoice for any Building Expense item which is limited to the Property or the
Building, as compared to the entire Project and such item does in fact benefit
the entire Project, Landlord shall have the right to invoice Tenant for Tenant's
proportionate share of such amount by using the Tenant's proportionate share of
the Project (which shall be calculated using the Rentable Area of the Premises
as the numerator and the rentable area of the Project as the denominator), as of
the date of the invoice; provided, however, that Landlord shall give Tenant a
credit for the amount which Tenant would have paid for such item, if any, during
the Base Year for Building Expenses. Landlord's invoice shall include reasonable
supporting documentation for such amount; Tenant shall pay such amounts within
thirty (30) days after receipt of an invoice.
 
6.5 Additional Rent Payments. Tenant's obligation to pay any additional rent
after the first Lease Year accruing during the Term pursuant to Sections 6.3 and
6.4 hereof shall apply pro rata to the proportionate part of a calendar year as
to Taxes and Building Expenses, in which this Lease begins or ends, for the
portion of each such year during which this Lease is in effect. Such obligation
to make payments of such additional rent shall survive the expiration or sooner
termination of the Term.
 
6.6 Payments. All payments or installments of any rent hereunder and all sums
whatsoever due under this Lease (including but not limited to court costs and
attorneys' fees) shall be deemed rent and shall be paid to Landlord at the
address designated by Landlord. If any amount of Annual Base Rent or additional
rent shall remain unpaid for five (5) calendar days after such payment becomes
due, Tenant shall pay Landlord, without notice or demand, a late charge equal to
the greater of (i) $35.00 and (ii) five percent (5%) of the such overdue amount
to partially compensate Landlord for its administrative costs in connection with
such overdue payment; which administrative costs Tenant expressly acknowledges
are reasonable and do not constitute a penalty. In addition, such overdue
amounts shall bear interest at the rate of 18% per annum (but not more than the
maximum allowable legal rate applicable to Tenant) (the "Default Rate") until
paid. Additionally, if any of Tenant's checks for payment of rent or additional
rent are returned to Landlord for insufficient funds, Tenant shall pay to
Landlord as additional rent the greater of (i) $50.00 or (ii) the amount of
actual charges incurred by Landlord, for each such check returned for
insufficient funds, and if two or more of Tenant's checks in payment of rent or
additional rent due hereunder are returned for insufficient funds in any
calendar year, Landlord reserves the right upon ten (10) days advance written
notice to Tenant to thereafter require Tenant to pay all rent and additional
rent and other sums whatsoever due under this Lease in cash, by money order or
by certified check or cashier's check. If an attorney is employed to enforce
Landlord's rights under this Lease, Tenant shall pay all fees and expenses of
such attorney whether or not legal proceedings are instituted by Landlord. Time
is of the essence in this Lease.
 
7.Requirements of Applicable Law. Landlord warrants that on the Commencement
Date, the Premises shall comply with all applicable laws, ordinances, rules and
regulations of governmental authorities having jurisdiction over the Property
("Applicable Laws"). Tenant, at its sole cost and expense, shall thereafter
comply promptly with all Applicable Laws now in force or which may hereafter be
in force, which impose any duty upon Landlord or Tenant with respect to the use,
occupancy or alteration of the Premises or any part thereof and for the
prevention of fires; provided, however, that Landlord and not Tenant shall
correct all structural defects in the Building necessary to comply with
Applicable Laws, and make all repairs, changes or alterations necessary because
the Building was not constructed in compliance with any of the Applicable Laws.
 
8.   Certificate of Occupancy. Tenant shall not use or occupy the Premises in
violation of any certificate of occupancy, permit, or other governmental consent
issued for the Building. If any governmental authority, after the commencement
of the Term, shall contend or declare that the Premises is being used for a
purpose which is in violation of such certificate of occupancy, permit, or
consent, then Tenant shall, upon five (5) days' notice from Landlord,
immediately discontinue such use of the Premises. If thereafter the governmental
authority asserting such violation threatens, commences or continues criminal or
civil proceedings against Landlord for Tenant's failure to discontinue such use,
in addition to any and all rights, privileges and remedies given to Landlord
under this Lease for default therein, Landlord shall have the right to terminate
this Lease forthwith. Tenant shall indemnify and hold Landlord harmless of and
from any and all liability for any such violation or violations.
 
9.   Contest-Statute, Ordinance, Etc. Tenant may, after notice to Landlord, by
appropriate proceedings conducted promptly at Tenant's own expense in Tenant's
name and whenever necessary in Landlord's name, contest in good faith the
validity or enforcement of any such statute, ordinance, law, order, regulation
or requirement and may similarly contest any assertion of violation of any
certificate of occupancy, permit, or any consent issued for the Building. Tenant
may, pending such contest, defer compliance therewith if, in the opinion of
counsel for Landlord, such deferral shall not subject either Landlord or the
Premises or the Property (or any part thereof) to any penalty, fine or
forfeiture, and if Tenant shall post a bond with corporate surety approved by
Landlord sufficient, in Landlord's opinion, fully to indemnify Landlord from
loss.
 
10.  Tenant's Improvements. Except to the extent that Landlord is responsible
for making improvements to the Premises pursuant to Section 35 of this Lease,
Tenant shall make such non-structural improvements to the Premises as it may
deem necessary at its sole cost and expense. Tenant shall not make any
alterations, decorations, installations, additions or improvements to the
Premises, including but not limited to, the installation of any fixtures,
amenities, equipment, appliances, or other apparatus, without Landlord's prior
written consent, and then only by contractors or mechanics employed or approved
by Landlord. All such work, alterations, decorations, installations, additions
or improvements shall be done at Tenant's sole expense and at such times and in
such manner as Landlord may from time to time designate. Landlord's consent to
and/or approval of Tenant's plans and specifications for the aforesaid
improvements shall create no responsibility or liability on the part of Landlord
for their completeness, design sufficiency, or compliance with all laws, rules
and regulations of governmental agencies or authorities. All alterations,
decorations, installations, additions or improvements made by either of the
parties hereto upon the Premises, except movable office furniture put in at the
expense of Tenant and other items as mutually agreed upon in writing, shall be
the property of Landlord and shall remain upon and be surrendered with the
Premises at the termination of this Lease without molestation or injury. Upon
request by Landlord, Tenant, at Tenant's expense, shall remove any and all
special improvements to the Premises or Common Areas made by or on behalf of
Tenant, including, without limitation, supplemental HVAC and raised flooring.
 

11.  
Repairs and Maintenance. 11.1 Tenant's Care of the Premises and Building. During
the Term Tenant shall:

(i) keep the Premises and the fixtures, appurtenances and improvements therein
in good order and condition;

            (ii)  make repairs and replacements to the Premises required because
of Tenant's misuse or primary negligence, except to the extent that the repairs
or replacements are covered by Landlord's insurance as required hereunder;
 
(iii)  repair and replace special equipment or decorative treatments installed
by or at Tenant's request and that serve the Premises only, except to the extent
the repairs or replacements are needed because of Landlord's misuse or primary
negligence, and are not covered by Tenant's insurance as required hereunder;
 
(iv)  pay for all damage to the Building, its fixtures and appurtenances, as
well as all damages sustained by Tenant or occupants of the Building due to any
waste, misuse or neglect of the Premises, its fixtures and appurtenances by
Tenant, except to the extent that the repair of such damage is covered by
Landlord's insurance as required hereunder to the extent that Landlord actually
receives proceeds therefrom; and
            
            (v)  not commit waste.
 
In addition Tenant shall not place a load upon any floor of the Premises
exceeding the floor load per square foot area which such floor was designed to
carry and which may be allowed under Applicable Laws. Landlord reserves the
right to prescribe the weight and position of all heavy equipment brought onto
the Premises and prescribe any reinforcing required under the circumstances, all
such reinforcing to be at Tenant's expense.
 
11.2 Landlord's Repairs. Except for the repairs and replacements that Tenant is
required to make pursuant to Section 11.1 above, Landlord shall make all other
repairs and replacements to the Premises, Common Areas and Building (including
Building fixtures and equipment) as shall be reasonably deemed necessary to
maintain the Building in a condition comparable to other first class suburban
office buildings in the Baltimore-Washington corridor area. This maintenance
shall include the roof, foundation, exterior walls, interior structural walls,
all structural components, and all systems such as mechanical, electrical,
multi-tenant HVAC, and plumbing. The costs associated with such repairs shall be
deemed a part of Building Expenses; provided, however, that costs of all of such
repairs which would be considered capital in nature under generally accepted
accounting principles shall be paid by Landlord. There shall be no allowance to
Tenant for a diminution of rental value, no abatement of rent, and no liability
on the part of Landlord by reason of inconvenience, annoyance or injury to
business arising from Landlord, Tenant or others making any repairs or
performing maintenance as provided for herein.
 
11.3 Time for Repairs. Repairs or replacements required pursuant to Section 11.1
and 11.2 above shall be made within a reasonable time (depending on the nature
of the repair or replacement needed - generally no more than fifteen (15) days)
after receiving notice or having actual knowledge of the need for a repair or
replacement.
 
11.4 Surrender of the Premises. Upon the termination of this Lease, without the
need for prior notice from Landlord, Tenant shall surrender the Premises to
Landlord in the same broom clean condition that the Premises were in on the
Commencement Date except for:
 
            (i)  ordinary wear and tear;
 
(ii)  damage by the elements, fire, and other casualty unless Tenant would be
required to repair under the provisions of this Lease;
 
(iii) damage arising from any cause not required to be repaired or replaced by
Tenant; and
 
(iv) alterations as permitted by this Lease unless consent was conditioned on
their removal.
 
On surrender Tenant shall remove from the Premises its personal property, trade
fixtures and any alterations required to be removed pursuant to the terms of
this Lease and repair any damage to the Premises caused by this removal. Any
items not removed by Tenant as required above shall be considered abandoned.
Landlord may dispose of abandoned items as Landlord chooses and bill Tenant for
the cost of their disposal.
 
12.   Conduct on Premises. Tenant shall not do, or permit anything to be done in
the Premises, or bring or keep anything therein which shall, in any way,
increase the rate of fire insurance on the Building, or invalidate or conflict
with the fire insurance policies on the Building, fixtures or on property kept
therein, or obstruct or interfere with the rights of Landlord or of other
tenants, or in any other way injure or annoy Landlord or the other tenants, or
subject Landlord to any liability for injury to persons or damage to property,
or interfere with the good order of the Building, or conflict with Applicable
Laws, or the Maryland Fire Underwriters Rating Bureau. Tenant agrees that any
increase of fire insurance premiums on the Building or contents caused by the
occupancy of Tenant and any expense or cost incurred in consequence of
negligence or carelessness or the willful action of Tenant, Tenant's employees,
agents, servants, or invitees shall, as they accrue be added to the rent
heretofore reserved and be paid as a part thereof., and Landlord shall have all
the rights and remedies for the collection of same as are conferred upon
Landlord for the collection of rent provided to be paid pursuant to the terms of
this Lease.
 
13.  Insurance.
 
13.1 Tenant's Insurance. Tenant shall keep in force at its own expense, so long
as this Lease remains in effect, (a) public liability insurance, including
insurance against assumed or contractual liability under this Lease, with
respect to the Premises, to afford protection with limits, per person and for
each occurrence, of not less than Two Million Dollars ($2,000,000), combined
single limit, with respect to personal injury and death and property damage,
such insurance to provide for only a reasonable deductible, (b) all-risk
property and casualty insurance, including theft, written at replacement cost
value and with replacement cost endorsement, covering all of Tenant's personal
property in the Premises and all improvements and installed in the Premises by
or on behalf of Tenant whether pursuant to the terms of Section 35, Section 10,
or otherwise, such insurance to provide for only a reasonable deductible, (c)
if, and to the extent, required by law, workmen's compensation or similar
insurance offering statutory coverage and containing statutory limits (d) shall
insure all plate and other interior glass in the Premises for and in the name of
Landlord and (e) business interruption insurance in an amount sufficient to
reimburse Tenant for loss of earnings attributable to prevention of access to
the Building or the Premises for a period of at least twelve (12) months. Such
policies shall be maintained in companies and in form reasonably acceptable to
Landlord and shall be written as primary policy coverage and not contributing
with, or in excess of, any coverage which Landlord shall carry. Tenant shall
deposit the policy or policies of such required insurance or certificates
thereof with Landlord prior to the Commencement Date, which policies shall name
Landlord or its designee and, at the request of Landlord, its mortgagees, as
additional insured and shall also contain a provision stating that such policy
or policies shall not be canceled except after thirty (30) days' written notice
to Landlord or its designees. All such policies of insurance shall be effective
as of the date Tenant occupies the Premises and shall be maintained in force at
all times during the Term of this Lease and all other times during which Tenant
shall occupy the Premises. In addition to the foregoing insurance coverage,
Tenant shall require any contractor retained by it to perform work on the
Premises to carry and maintain, at no expense to Landlord, during such times as
contractor is working in the Premises, a non-deductible (i) comprehensive
general liability insurance policy, including, but not limited to, contractor's
liability coverage, contractual liability coverage, completed operations
coverage, broad form property damage endorsement and contractor's protective
liability coverage, to afford protection with limits per person and for each
occurrence, of not less than Two Hundred Thousand Dollars ($200,000.00),
combined single limit, with respect to personal injury and death and property
damage, such insurance to provide for no deductible, and (ii) workmen's
compensation insurance or similar insurance in form and amounts as required by
law. In the event of damage to or destruction of the Premises and the
termination of this Lease by Landlord pursuant to Section 18 herein, Tenant
agrees that it shall pay Landlord all of its insurance proceeds relating to
improvements made in the Premises by or on behalf of Tenant whether pursuant to
the terms of Section 35, Section 10, or otherwise. If Tenant fails to comply
with its covenants made in this Section, if such insurance would terminate or if
Landlord has reason to believe such insurance is about to be terminated,
Landlord may at its option cause such insurance as it in its sole judgment deems
necessary to be issued, and in such event Tenant agrees to pay promptly upon
Landlord's demand, as additional rent the premiums for such insurance.

 
13.2 Landlord's Insurance. Landlord shall keep in force at its own expense (a)
contractual and comprehensive general liability insurance, including public
liability and property damage, with a minimum combined single limit of liability
of Two Million Dollars ($2,000,000.00) for personal injuries or death of persons
occurring in or about the Building and Premises, and (b) all-risk property and
casualty insurance written at replacement cost value covering the Building and
all of Landlord's improvements in and about same.
 
13.3 Waiver of Subrogation. Each party hereto waives claims arising in any
manner in its favor and against the other party and agrees that neither party
hereto shall be liable to the other party or to any insurance company (by way of
subrogation or otherwise) insuring the other party for any loss or damage to the
Building, the Premises or other tangible property, or any resulting loss of
income, or losses under worker's compensation laws and benefits, or against
liability on or about the Building, even though such loss or damage might have
been occasioned by the negligence of such party, its agents or employees if any
such loss or damage is covered by insurance benefiting the party suffering such
loss or damage as was required to be covered by insurance carried pursuant to
this Lease. Landlord shall cause each insurance policy carried by it insuring
against liability on or about the Building or insuring the Premises and the
Building or income resulting therefrom against loss by fire or any of the
casualties covered by the all-risk insurance carried by it hereunder to be
written in such a manner as to provide that the insurer waives all right of
recovery by way of subrogation against Tenant in connection with any loss or
damage covered by such policies. Tenant shall cause each insurance policy
carried by it insuring against liability or insuring the Premises (including the
contents thereof and Tenant's Improvements installed therein by Tenant or on its
behalf) against loss by fire or any of the casualties covered by the all-risk
insurance required hereunder to be written in such a manner as to provide that
the insurer waives all right of recovery by way of subrogation against Landlord
in connection with any loss or damage covered by such policies.
 
14.   Rules and Regulations. Tenant shall be bound by the rules and regulations
set forth on the schedule attached hereto as Exhibit "B" and made a part hereof.
Landlord shall have the right, from time to time, to issue additional or amended
rules and regulations regarding the use of the Building, so long as the rules
shall be reasonable and non-discriminatory between tenants. When so issued the
same shall be considered a part of this Lease and Tenant covenants that the
additional or amended rules and regulations shall likewise be faithfully
observed by Tenant, the employees of Tenant and all persons invited by Tenant
into the Building, provided, that the additional or amended rules are made
applicable to all office tenants similarly situated as Tenant. Landlord shall
not be liable to Tenant for the violation of any of the rules and regulations,
or the breach of any covenant or condition in any lease, by any other tenant in
the
 
Building.
 
15.   Mechanics' Liens. Tenant shall not do or suffer to be done any act, matter
or thing whereby Tenant's interest in the Premises, or any part thereof, may be
encumbered by any mechanics' lien. Tenant shall discharge or bond off, within
ten (10) days after the date of filing, any mechanics' liens filed against
Tenant's interest in the Premises, or any part thereof, purporting to be for
labor or material furnished or to be furnished to Tenant. Landlord shall not be
liable for any labor or materials furnished or to be furnished to Tenant upon
credit, and no mechanics' or other lien for labor or materials shall attach to
or affect the reversionary or other estate or interest of Landlord in and to the
Premises, or the Property.
 
16.   Tenant's Failure to Repair. In the event that Tenant fails after
reasonable prior written notice from Landlord, to keep the Premises in a good
state of condition and repair pursuant to Section 11 above, or to do any act or
make any payment required under this Lease or otherwise fails to comply
herewith, Landlord may, at its option (but without being obliged to do so)
immediately, or at any time thereafter and without notice, perform the same for
the account of Tenant, including the right to enter upon the Premises at all
reasonable hours to make such repairs, or do any act or make any payment or
compliance which Tenant has failed to do, and upon demand, Tenant shall
reimburse Landlord for any such expense incurred by Landlord including but not
limited to any costs, damages and counsel fees. Any moneys expended by Landlord,
as aforesaid, shall be deemed additional rent, collectible as such by Landlord.
All rights given to Landlord in this Section shall be in addition to any other
right or remedy of Landlord herein contained.

17.  Property -- Loss, Damage. Landlord, its agents and employees shall not be
liable to Tenant for (i) any damage or loss of property of Tenant placed in the
custody of persons
employed to provide services for or stored in or about the Premises and/or the
Building, unless such damage or loss is the result of the negligence of
Landlord, (ii) any injury or damage to persons, property or the business of
Tenant resulting from a latent defect in or material change in
the condition of the Building, and (iii) interference with the light, air, or
other incorporeal hereditaments of the Premises.
 
18.  Destruction -- Fire or Other Casualty. In case of partial damage to the
Premises by fire or other casualty insured against by Landlord, Tenant shall
give immediate notice thereof to Landlord, who shall thereupon cause damage to
all property owned by it to be repaired with reasonable speed at expense of
Landlord, due allowance being made for reasonable delay which may arise by
reason of adjustment of loss under insurance policies on the part of Landlord
and/or Tenant, and for reasonable delay on account of "labor troubles" or any
other cause beyond Landlord's control, and to the extent that the Premises is
rendered unten=able the rent shall proportionately abate from the date of such
casualty, provided the damage above mentioned occurred without the fault or
neglect of Tenant, Tenant's servants, employees, agents or visitors. If such
partial damage is due to the fault or neglect of Tenant, or Tenant's servants,
employees, agents, or invitees, the damage shall be repaired by Landlord to the
extent of Landlord's insurance coverage, but there shall be no apportionment or
abatement of rent. In the event the damage shall be so extensive to the whole
Building as to render it uneconomical, in Landlord's reasonable opinion, to
restore for its present uses and Landlord shall decide not to repair or rebuild
the Building, this Lease, at the option of Landlord or Tenant, upon written
notice to the other party, shall be terminated upon written notice to Tenant and
the rent shall, in such event, be paid to or adjusted as of the date of such
damage, and the terms of this Lease shall expire by lapse of time and
conditional limitation upon the third day after such notice is mailed, and
Tenant shall thereupon vacate the Premises and surrender the same to Landlord,
but no such termination shall release Tenant from any liability to Landlord
arising from such damage or from any breach of the obligations imposed on Tenant
hereunder, or from any obligations accrued hereunder prior to such termination.
 
19.  Eminent Domain. If (1) the whole or more than fifty percent (50%) of the
floor area of the Premises shall be taken or condemned by Eminent Domain for any
public or quasi-public use or purpose, and either party shall elect, by giving
written notice to the other, or (2) more than twenty-five percent (25%) of the
floor area of the Building shall be so taken, and Landlord shall elect, in its
sole discretion, by giving written notice to Tenant, any written notice to be
given not more than sixty (60) days after the date on which title shall vest in
such condemnation proceeding, to terminate this Lease, then, in either such
event, the Term of this Lease shall cease and terminate as of the date of title
vesting. In case of any taking or condemnation, whether or not the Term of this
Lease shall cease and terminate, the entire award shall be the property of
Landlord, and Tenant hereby assigns to Landlord all its right, title and
interest in and to any such award, except that Tenant shall be entitled to
claim, prove and receive in the proceedings such awards as may be allowed for
moving expenses, loss of profit and fixtures and other equipment installed by it
which shall not, under the terms of this Lease, be or become the property of
Landlord at the termination hereof, but only if such awards shall be made by the
condemnation, court or other authority in addition to, and be stated separately
from, the award made by it for the Property or part thereof so taken.
 
20.  Assignment. So long as Tenant is not in default of any of the terms and
conditions hereof, after the giving of all required notices and the expiration
of all cure periods, Landlord shall not unreasonably withhold its consent to an
assignment of this Lease or sublease of the Premises for any of the then
remaining portion of the unexpired Term provided: (i) the net assets of the
assignee or sublessee shall not be less than the net assets of Tenant at the
time of the signing of this Lease; (ii) in the event of an assignment, such
assignee shall assume in writing all of Tenant's obligations under this Lease;
(iii) in the event of a sublease, such sublease shall in all respects be subject
to and in conformance with the terms of this Lease; (iv) the proposed assignee
or sublessee shall not be occupying other space in the Building, nor shall it be
a prospective tenant either then negotiating with Landlord or having negotiated
with Landlord for premises within the prior six (6) month period; and (v) in all
events Tenant continues to remain liable on this Lease for the performance of
all terms, including but not limited to, payment of all rent due hereunder.
Landlord and Tenant acknowledge and agree that it shall not be unreasonable for
Landlord to withhold its consent to an assignment if in Landlord's sole business
judgment, the assignee lacks sufficient business experience or net worth to
successfully operate its business within the Premises in accordance with the
terms, covenants and conditions of this Lease. If this Lease be assigned, or if
the Premises or any part thereof be sublet or occupied by anybody other than
Tenant, Landlord may, after default by Tenant, collect rent from the assignee,
subtenant or occupant and apply the net amount collected to the rent herein
reserved, but no such collection shall be deemed a waiver of this covenant, or
the acceptance of the assignee, subtenant or occupant as tenant, or a release of
Tenant from the further observance and performance by Tenant of the covenants
herein contained. Fifty percent (50%) of any profit or additional consideration
or rent in excess of the Base Rent or additional rent payable by Tenant
hereunder which is payable to Tenant as a result of any assignment or subletting
shall be paid to Landlord as additional rent when received by Tenant. No
assignment or sublease, regardless of whether Landlord's consent has been
granted or withheld, shall be deemed to release Tenant from any of its
obligations nor shall the same be deemed to release any person guaranteeing the
obligations of Tenant hereunder from their obligations as guarantor.
 
Notwithstanding the foregoing, without the consent and approval of Landlord,
Tenant shall have the right to assign or sublease the Premises or any portion
thereof without Landlord's consent (however, Tenant shall endeavor to provide
ten (10) days' prior written notice thereof along with a true and complete copy
of the sublease or assignment document) to any subsidiary or affiliate of Tenant
or in the event of a merger or a sale of all or substantially all of the
Tenant's assets, and in any event shall notify Landlord in writing within thirty
(30) days of the effective date of such assignment or sublease. For the purposes
hereof, "affiliate" shall mean an entity or individual which controls, is
controlled by or is under the common control with Tenant. Tenant shall remain
liable under the terms hereof if Tenant exercises its rights under this
paragraph to the extent it survives such corporate event.
 
21. Default; Remedies; Bankruptcy of Tenant. Any one or more of the following
events shall constitute an "Event of Default" hereunder, at Landlord's election:
(a) the sale of Tenant's interest in the Premises under attachment, execution or
similar legal process or, the adjudication of Tenant as a bankrupt or insolvent,
unless such adjudication is vacated within thirty (30) days; (b) the filing of a
voluntary petition proposing the adjudication of Tenant (or any guarantor of
Tenant's obligations hereunder) as a bankrupt or insolvent, or the
reorganization of Tenant (or any such guarantor), or an arrangement by Tenant
(or any such guarantor) with its creditors, whether pursuant to the Federal
Bankruptcy Code or any similar federal or state proceeding, unless such petition
is filed by a party other than Tenant (or any such guarantor) and is with-drawn
or dismissed within thirty (30) days after the date of its filing; (c) the
admission, in writing, by Tenant (or any such guarantor) of its inability to pay
its debts when due; (d) the appointment of a receiver or trustee for the
business or property of Tenant (or any such guarantor), unless such appointment
is vacated within thirty (30) days of its entry; (e) the making by Tenant (or
any such guarantor) of an assignment for the benefit of its creditors, or if, in
any other manner, Tenant's interest in this Lease shall pass to another by
operation of law; (f) the failure of Tenant to pay any rent, additional rent or
other sum of money when due and such failure continues for a period of ten (10)
days after receipt of written notice that the same is past due hereunder; (g) if
Tenant fails to pay any rent or additional rent when due after Landlord shall
have given Tenant written notice with respect to such non-payment twice in any
twelve (12) month period as provided in subsection (f) above; (h) Tenant shall
fail to move into or take possession of the Premises within thirty (30) days
after commencement of the Term or having taken possession shall thereafter
abandon and/or vacate the Premises; and (i) the default by Tenant in the
performance or observance of any covenant or agreement of this Lease (other than
a default involving the payment of money), which default is not cured within
thirty (30) days after the giving of notice thereof by Landlord, unless such
default is of such nature that it cannot be cured within such thirty (30) day
period, in which case no Event of Default shall occur so long as Tenant shall
commence the curing of the default within such thirty (30) day period and shall
thereafter diligently prosecute the curing of same.
 
Upon the occurrence and continuance of an Event of Default, Landlord, with such
notice to Tenant as provided for by law or as expressly provided for herein, may
do any one or more of the following: (a) sell, at public or private sale, all or
any part of the goods, chattels, fixtures and other personal property belonging
to Tenant which are or may be put into the Premises during the Term, whether or
not exempt from sale under execution or attachment (it being agreed that the
property shall at all times be bound with a lien in favor of Landlord and shall
be chargeable for all rent and for the fulfillment of the other covenants and
agreements herein contained), and apply the proceeds of such sale, first, to the
payment of all costs and expenses of conducting the sale or caring for or
storing the property; second, toward the payment of any indebtedness, including,
without limitation, indebtedness for rent, which may be or may become due from
Tenant to Landlord; and third, to pay Tenant, on demand in writing, any surplus
remaining after all indebtedness of Tenant to Landlord has been fully paid; (b)
perform, on behalf and at the expense of Tenant, any obligation of Tenant under
this Lease which Tenant has failed to perform and of which Landlord shall have
given Tenant notice, the cost of which performance by Landlord, together, with
interest thereon at the rate of eighteen percent (18%) per annum, from the date
of such expenditure, shall be deemed additional rent and shall be payable by
Tenant to Landlord upon demand; (c) elect to terminate this Lease and the
tenancy created hereby by giving notice of such election to Tenant, and on
notice reenter the Premises, by summary proceedings or otherwise, and remove
Tenant and all other persons and property from the Pre-mises, and store such
property in a public warehouse or elsewhere at the cost and for the account of
Tenant, without resort to legal process and without Landlord being deemed guilty
of trespass or becoming liable for any loss or damage occasioned thereby; and
also the right, but not the obligation, to re-let the Premises for any unexpired
balance of the Term, and collect the rent therefor. In the event of such
re-letting by Landlord, the re-letting shall be on such terms, conditions and
rental as Landlord may deem proper, and the proceeds that may be collected from
the same, less the expense of re-letting (including reasonable leasing fees and
commissions and reasonable costs of renovating the Premises), shall be applied
upon Tenant's rental obligation as set forth in this Lease for the unexpired
portion of the Term. Tenant shall have no further right of possession of the
Premises; and (d) exercise any other legal or equitable right or remedy which it
may have at law or in equity. Notwithstanding the provisions of clause (b) above
and regardless of whether an Event of Default shall have occurred, Landlord may
exercise the remedy described in clause (b) without any notice to Tenant if
Landlord, in its good faith judgment, believes it would be materially injured by
the failure to take rapid action, or if the unperformed obligation of Tenant
constitutes an emergency.
 
To the extent permitted by law, Tenant hereby expressly waives any and all
rights of redemption, granted by or under any present or future laws in the
event of Tenant's being evicted or dispossessed for any cause, or in the event
of Landlord's obtaining possession of the Premises, by reason of the violation
by Tenant of any of the covenants and conditions of this Lease, or otherwise.
Landlord and Tenant hereby expressly waive trial by jury in any action or
proceeding or counterclaim brought by either party hereto against the other
party on any and every matter, directly or indirectly arising out of or with
respect to this Lease, including, without limitation, the relationship of
Landlord and Tenant, the use and occupancy by Tenant of the Premises, any
statutory remedy andlor claim of injury or damage regarding this Lease.
 
Any costs and expenses incurred by Landlord (including, without limitation,
reasonable attorneys' fees) in enforcing any of its rights or remedies under
this Lease shall be deemed to be additional rent and shall be repaid to Landlord
by Tenant upon demand.
 
Notwithstanding any of the other provisions of this Lease, in the event Tenant
shall voluntarily or involuntarily come under the jurisdiction of the Federal
Bankruptcy Code and thereafter Tenant or its trustee in bankruptcy, under the
authority of and pursuant to applicable provisions thereof, shall have the power
and so using same determine to assign this Lease, Tenant agrees that (i) Tenant
or its trustee shall provide to Landlord sufficient information enabling it to
independently determine whether Landlord will incur actual and substantial
detriment by reason of such assignment and (ii) "adequate assurance of future
performance" under this Lease, as that term is generally defined under the
Federal Bankruptcy Code, shall be provided to Landlord by Tenant and its
assignee as a condition of the assignment.
 
Notwithstanding anything to the contrary contained herein, Tenant shall be
considered in "Habitual Default" of this Lease upon (a) Tenant's failure, on two
(2) or more occasions during any twelve month period to pay when due any
installment of Base Rent, additional rent or any other sum required by the terms
of this Lease, or upon (b) Tenant's failure, on two (2) or more occasions during
any twelve month period to comply with any term, covenant or condition of this
Lease after written notice by Landlord to Tenant. Upon the occurrence of an
event of Habitual Default on the part of Tenant, then without limiting any other
rights or remedies to which Landlord may be entitled as a result of such
defaults: (i) Tenant shall immediately be deemed to have relinquished any and
all rights of renewal, rights to terminate, rights of first offer or rights of
first refusal or similar rights granted or to be granted under the terms of this
Lease or any amendment hereto ; and (ii) in the event of a monetary event of
Habitual Default, Tenant shall thereafter pay all Base Rent and additional rent
and other sums whatsoever due under this Lease in cash, by money order or by
certified check or cashier's check.
 
22.   Damages. If this Lease is terminated by Landlord pursuant to Section 21,
Tenant shall, nevertheless, remain liable for all rent and damages which may be
due or sustained prior to such termination, and all reasonable costs, fees and
expenses including, but not limited to, attorneys' fees, costs and expenses
incurred by Landlord in pursuit of its remedies hereunder, or in renting the
Premises to others from time to time and additional damages (the "Liquidated
Damages"), which shall be an amount equal to the total rent which, but for
termination of this Lease, would have become due during the remainder of the
Term, less the amount of rent, if any, which Landlord shall receive during such
period from others to whom the Premises may be rented (other than any additional
rent received by Landlord as a result of any failure of such other person to
perform any of its obligations to Landlord), in which case such Liquidated
Damages shall be computed and payable in monthly installments, in advance on the
first day of each calendar month following termination of the Lease and
continuing until the date on which the Term would have expired but for such
termination, and any suit or action brought to collect any such Liquidated
Damages for any month shall not in any manner prejudice the right of Landlord to
collect any Liquidated Damages for any subsequent month by a similar proceeding.
 
If this Lease is terminated pursuant to Section 21, Landlord may relet the
Premises or any part thereof, alone or together with other premises, for such
term(s) which may be greater or less than the period which otherwise would have
constituted the balance of the Term and on such terms and conditions (which may
include concessions, free rent and/or alterations of the Premises) as Landlord,
in its sole discretion, may determine, but Landlord shall not be liable for, nor
shall Tenant's obligations hereunder be diminished by reason of, any failure by
Landlord to relet the Premises or any failure by Landlord to collect any rent
due upon such reletting.
 
23.  Services and Utilities. Landlord shall provide the following listed
services and utilities, namely:
 
(a)  heating, ventilation, and air conditioning ("HVAC") for the Premises
during"Normal Business Hours" (as defined below) to maintain temperatures for
comfortable use and occupancy;
 
(b)  electric energy in accordance with Section 24 following;
 
      (c)  automatic passenger elevators providing adequate service leading to
the floor on which the Premises is located;
 
(d)  evening, unescorted janitorial services to the Premises including removal
of trash;
(e)  hot and cold water sufficient for drinking, lavatory toilet and ordinary
cleaning purposes from fixtures either within the Premises (if provided pursuant
to this Lease) or on the floor on which the Premises  is located;
 
    (f) replacement of lighting tubes, lamp ballasts and bulbs;
        (g)  extermination and pest control when and if necessary; and
 
(h)  maintenance of Common Areas in a manner comparable to other first class
suburban office buildings in the Baltimore-Washington corridor.
 
Notwithstanding the foregoing, if at any time during the Term, Landlord shall,
after reasonable investigation determine that trash and similar waste generated
by Tenant and/or emanating from the Premises is in excess of that of other
standard office tenants within the Building leasing a premises of the same or
similar size to that of the Premises, Landlord shall bill Tenant and Tenant
shall pay to Landlord as additional rent hereunder within thirty (30) days of
the date of Landlord's invoice for the same, those costs and expenses of trash
removal which are reasonably attributable to such excess trash and similar waste
generated by Tenant and/or emanating from the Premises. "Normal Business Hours"
as used herein is defined from 8:00 a.m. to 6:00 p.m. on business days and from
8:00 a.m. to 1:00 p.m. on Saturdays. Landlord shall have no responsibility to
provide any services under (a) above except during Normal Business Hours unless
arrangements for after-hours services have been made pursuant to terms and
conditions acceptable to Landlord and embodied in a separate written agreement
between Landlord and Tenant. Landlord reserves the right to require Tenant, at
Tenant's expense, to install separate meters to monitor electrical consumption
if Landlord determines, in its reasonable discretion that such monitoring is
necessary based on Tenant's electrical usage. Landlord reserves the right to
stop service of the HVAC, elevator, plumbing and electric systems, when
necessary, by reason of accident, or emergency, or for repairs, alterations,
replacements, or improvements, which in the judgment of Landlord are desirable
or necessary to be made, until the repairs, alterations, replacements, or
improvements shall have been completed. Landlord shall have no responsibility or
liability for failure to supply HVAC, elevator, plumbing, cleaning, and electric
service, during the period when prevented from so doing by laws, orders, or
regulations of any Federal, State, County or Municipal authority or by strikes,
accidents or by any other cause whatsoever beyond Landlord's control. Landlord's
obligations to supply HVAC are subject to applicable laws and regulations as to
energy conservation and other such restrictions. Landlord acknowledges that
Tenant will require supplemental HVAC for the Premises, which may be installed
subject to the following conditions: 1) any maintenance repair and/or
replacement required for such supplemental service shall be performed by
Landlord but the cost of such maintenance repair and/or replacement (including
labor and materials) shall be paid by Tenant as additional rent; (2) the
supplemental units shall be installed by Landlord and submetered, both at
Tenant's sole cost and expenses; and
 
(3)  the submeter will be read by Landlord and billed back to Tenant, which
Tenant shall pay, as additional rent, within thirty (30) days of Tenant's
receipt therefore.
 
24. Electric Current. Throughout the Term Landlord shall furnish Tenant without
additional charge during Normal Business Hours (as defined in Section 23) a
reasonable amount of electric current at 110 volts ("Normal Usage Amount") for
lighting purposes within the Premises and the powering of a normal amount of
office equipment and appliances. "Normal Usage Amount" is defined for purposes
of this Lease to mean electric power supplied at the rate of three (3) watts per
square foot of Premises. In this regard Tenant agrees as follows:
 
(1)  If Landlord reasonably determines based upon engineering studies of
electrical load consumed that Tenant is materially exceeding the Normal Usage
Amount Tenant shall pay
to Landlord such amounts as additional rent as will equitably reimburse Landlord
for the cost of the extra electric power so consumed by Tenant;
 
(2)  If Tenant shall desire to place and install in the Premises electric
equipment or appliances other than normal and typical to general office usage it
shall pay for such installations including any additional electric lines and
facilities required and shall pay for the electric power used in such equipment
if same exceeds Normal Usage Amount.
 
Landlord has advised Tenant that present Baltimore Gas & Electric ("Electric
Service Provider") is the utility company selected by Landlord to provide
electricity to the Building. Notwithstanding the foregoing, if permitted by law,
Landlord shall have the right at any time and from time to time during the Term
to either contract for service from a different company or companies providing
electricity service (each such company shall hereinafter be referred to as an
"Alternative Service Provider") or continue to contract for service from the
Electric Service Provider.
 
Tenant shall cooperate with Landlord, the Electric Service Provider and any
Alternate Service Provider at all times and, as reasonably necessary, shall
allow Landlord, the Electric Service Provider, and any Alternative Service
Provider reasonable access to the Building's electric lines, feeders, risers,
wiring and any other machinery within the Premises, provided that
Landlord shall use its reasonable efforts to minimize its interference with
Tenant's business in the Premises.

 
25.   Telephone and Telecommunications. Landlord has arranged for the
installation of telephone service within the Building to the ground floor
telephone utility closet and conduit to the ground floor telephone and
electrical riser closets. Tenant shall be responsible for contacting the utility
company supplying the telephone service and arranging to have such telephone
facilities as it may desire to be extended and put into operation in the
Premises, including without limitation, obtaining a low voltage permit for phone
and data wiring. Tenant acknowledges and agrees that all telephone and
telecommunications services desired by Tenant shall be ordered and utilized at
the sole expense of Tenant. All costs related to installation and the provision
of such service shall be borne and paid for directly by Tenant. Upon request by
Landlord, Tenant, at Tenant's expense, shall remove the telephone facilities at
the expiration or sooner termination of the Term. Tenant shall obtain the
requisite permit and complete the ceiling work in cooperation with Landlord in
order not to interfere with or delay the completion of the Tenant Improvements
by Landlord pursuant to Section 35, including, without limitation, the closing
of the ceiling and the carpet installation, if applicable. Landlord will allow
Tenant access for wiring, including electric, data and telecom, within the
Building's public areas and designated chases, but will not guarantee access of
the wiring through another tenant's space. Tenant, at Tenant's expense, shall be
responsible for the relocation and its associated costs, if requested, of any
data, telecom or electrical wiring that runs through another tenant's space,
including the plenum area or otherwise.
 
In the event Tenant wishes to utilize the services of a telephone or
telecommunications provider whose equipment is not servicing the Building at
such time Tenant wishes to install its telecommunications equipment serving the
Premises ("Provider"), no such Provider shall be permitted to install its lines
or other equipment without first securing the prior written consent of Landlord,
which consent shall not be unreasonably withheld. Prior to the commencement of
any work in or about the Building by the Provider, the Provider shall agree to
abide by such rules and regulations, job site rules, and such other requirements
as reasonably determined by Landlord to be necessary to protect the interest of
the Building and Property, the other tenants and occupants of the Building and
Landlord, including, without limitation, providing security in such form and
amount as reasonable determined by Landlord. Each Provider must be duly
licensed, insured and reputable. Landlord shall incur no expense whatsoever with
respect to any aspect of Provider's provision of its services, including without
limitation, the costs of installation, materials and service.
 
In addition, Landlord reserves exclusively to itself and its successors and
assigns the right to install, operate, maintain, repair, replace and remove
fiber optic cable and conduit and associated equipment and appurtenances within
the Building and the Premises so as to provide telecommunications service to and
for the benefit of tenants and other occupants of the Building.
 
26.   Acceptance of Premises. Tenant shall have reasonable opportunity, provided
it does not thereby interfere with Landlord's work, to examine the Premises to
determine the condition thereof. Upon taking possession of the Premises, Tenant
shall be deemed to have accepted same as being satisfactory and in the condition
called for hereunder, except for latent defects and punch list items previously
noted to Landlord.
 
27.   Inability to Perform. This Lease and the obligation of Tenant to pay rent
hereunder and perform all of the other covenants and agreements hereunder on the
part of Tenant to be per-formed shall in no way be affected, impaired or excused
because Landlord is unable to fulfill any of its obligations under this Lease or
to supply, or is delayed in supplying, any service to be supplied by it under
the terms of this Lease or is unable to make, or is delayed in making any
repairs, additions, alterations, or decorations or is unable to supply, or is
delayed in supplying, any equipment or fixtures if Landlord is prevented or
delayed from so doing by reason of strikes or labor troubles or any outside
cause whatsoever including, but not limited to, governmental preemption in
connection with a National Emergency, or by reason of any rule, order or
regulation of any department or subdivision of any government agency or by
reason of the conditions of supply and demand which have been or are affected by
war or other emergency. Similarly, Landlord shall not be liable for any
interference with any services supplied to Tenant by others if such interference
is caused by any of the reasons listed in this Section. Nothing contained in
this Section shall be deemed to impose any obligation on Landlord not expressly
imposed by other sections of this Lease.

    Notwithstanding anything herein to the cont, aryif (i) the services or
utilities described in Section 23 hereof are interrupted for a period of more
than seven (7) consecutive business days, (ii) such interruption is not the
result of strikes, unavailability of parts or other materials, or any other
cause beyond Landlord's reasonable control, and (iii) such interruption renders
a material portion of the Premises unusable by Tenant, then Tenant shall be
entitled to a pro rata abatement of rent beginning on the eighth (8th)
consecutive business day that such portion of the Premises
 
are unusable and continuing until the use of all or a substantial portion of the
Premises is restored to Tenant.
 

28.  
No Waivers. 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, shall not be construed as a waiver, or a
relinquishment for the future, of such covenant or option, but the same shall
continue and remain in full force and effect. The receipt by Landlord of rent,
with knowledge of the breach of any covenant hereof, shall not be deemed a
waiver of such

 
breach, and no waiver by Landlord of any provision hereof shall be deemed to
have been made unless expressed in writing and signed by Landlord.
 
29.  Access to Premises and Change in Services. Landlord shall have the right,
without abatement of rent, to enter the Premises at any hour to examine the
same, or to make such repairs and alterations as Landlord shall deem necessary
for the safety and preservation of the Building, and also to exhibit the
Premises to be let; provided, however, that except in the case of emergency such
entry shall only be after notice first given to Tenant. If, during the last
month of the Term, Tenant shall have removed all or substantially all of
Tenant's property therefrom, Landlord may immediately enter and alter, renovate
and redecorate the Premises, without elimination or abatement of rent, or
incurring liability to Tenant for any compensation, and such acts shall have no
effect upon this Lease. Nothing herein contained, however, shall be deemed or
construed to impose upon Landlord any obligation, responsibility or liability
whatsoever, for the care, supervision or repair, of the Building or any part
thereof, other than as herein elsewhere expressly provided. Landlord shall also
have the right at any time, without the same constituting an actual or
constructive eviction and without incurring any liability to Tenant therefor, to
change the arrangement and/or location of entrances or passageways, doors and
doorways, and corridors, stairs, toilets, elevators, or other public parts of
the Building, and to change the name by which the Building is commonly known
and/or its mailing address.
 
30.  Estoppel Certificates. Tenant agrees, at any time and from time to time,
upon not less than ten (10) days' prior request by Landlord to execute,
acknowledge and deliver to Landlord an estoppel certificate substantially in the
form attached hereto as Exhibit "D" or such other reasonable form requested by
Landlord which certifies that this Lease is unmodified and in full force (or if
there have been modifications, that the same is in full force and effect as
modified and stating the modifications) and the dates through which the rent and
other charges have been paid in advance, if any, and stating whether or not to
the best knowledge of the signer of such certificate Landlord is in default in
performance of any covenant, agreement or condition contained in this Lease and,
if so, specifying each such default of which the signer may have
 
knowledge, it being intended that any such statement delivered hereunder may be
relied upon by third parties not a party to this Lease.
 
31.  Subordination. Tenant accepts this Lease, and the tenancy created
hereunder, subject and subordinate to any mortgages, overleases, leasehold
mortgages or other security interests now or hereafter a lien upon or affecting
the Building or the Property or any part thereof. Tenant shall, at any time
hereafter, within ten (10) days after request from Landlord, execute a
Subordination, Non-Disturbance Agreement substantially in the form of Exhibit
"E" attached hereto and made a part hereof or any instruments or leases or other
documents that may be required by any mortgage or mortgagee or overlandlord
(herein a "Mortgagee") for the purpose of subjecting or subordinating this Lease
and the tenancy created hereunder to the lien of any such mortgage or
 
mortgages or underlying lease, and the failure of Tenant to execute any such
instruments, releases or documents shall constitute a default hereunder.
 
32.  Attomment. Tenant agrees that upon any termination of Landlord's interest
in the Premises, Tenant shall, upon request, attorn to the person or
organization then holding title to the reversion of the Premises (the
"Successor") and to all subsequent Successors, and shall pay to the Successor
all of the rents and other monies required to be paid by Tenant hereunder and
perform all of the other terms, covenants, conditions and obligations in this
Lease contained; provided, however, that if in connection with such attornment
Tenant shall so request from such Successor in writing, such Successor shall
execute and deliver to Tenant an instrument wherein such Successor agrees that
as long as Tenant performs all of the terms, covenants and conditions of this
Lease, on Tenant's part to be performed, Tenant's possession under the
provisions of this Lease shall not be disturbed by such Successor.

diligently prosecute the issuance of the permits and then finish or cause the
Premises to be finished in accordance therewith.

an amount equal to one hundred fifty percent (150%) of the monthly Base Rent
stated in Section 1.1.8 paid immediately prior to the holding over period for
each month or part of a month that Tenant holds over, plus all other payments
provided for herein, and the payment and acceptance of such payments shall not
constitute an extension or renewal of this Lease. In event of any such holdover,
Landlord shall also be entitled to all remedies provided by law for the speedy
eviction of tenants, and to the payment of all attorneys' fees and expenses
incurred in connection therewith.
 
38.   Members' Liability. It is understood that the Owner of the Building is a
Maryland limited liability company. All obligations of the Owner hereunder are

the obligations of Owner hereunder.

expression of their agreement and is a complete and exclusive statement of its
terms, and all negotiations, considerations and representations between the
Parties are incorporated. No course of prior dealings between the Parties or
their affiliates shall be relevant or admissible to supplement, explain, or vary

satisfaction that such Hazardous Material is necessary or useful to Tenant's
business and shall be used, kept and stored in a manner that complies with all
laws regulating any such Hazardous Material so brought upon or used or kept in
or about the Premises). If Tenant breaches the obligations stated in the
preceding sentence, or if the presence of Hazardous Material on the Premises
caused or permitted by Tenant results in contamination of the Premises, the
Building and/or the Property, or if contamination of the Premises, the Building

contained in this Lease and with the purpose of superseding any such provisions
herein that might be construed to the contrary, it is the intent of Landlord and

provisions shall be deemed their specific agreement as to how the responsibility
for compliance (and cost) with the Americans With Disabilities Act and
amendments to same ("ADA"), both as to the Premises and the Property, shall be
allocated between them, namely:
 
47.1 Landlord and Tenant agree to cooperate together in the initial design,
planning and preparation of specifications for construction of the Premises so
that same shall be in compliance with the A. Any costs associated with assuring
that the plans and specifications for the construction of the Premises are in
compliance with the ADA shall be borne by the party whose responsibility it is
hereunder to bear the cost of preparation of the plans and specifications.
Similarly those costs incurred in the initial construction of the Premises so
that same are built in compliance with the ADA shall be included within Tenant's
Improvements and handled in the manner as provided for in other Sections of this
Lease.

    47.2 Subject to Section 47.4, modifications, alterations and/or other
changes required to and within the Common Areas which are not capital in nature
shall be the responsibility of Landlord to perform and the cost of same shall be
considered a part of the Building Expenses and treated as such.
 
47.3 Subject to Section 47.4, modifications, alterations and/or other changes
required to and within the Common Areas which are capital in nature shall be the
responsibility of Landlord and at its cost and expense.
 
47.4 Modifications, alterations and/or other changes required to and within the
Common Areas, whether capital in nature or not, which are required as a result
of Tenant's specific use of the Premises, as compared to office uses generally,
shall be paid by Tenant within thirty (30) days after receipt of an invoice from
Landlord, together with reasonable supporting documentation.
 
47.5 Modifications, alterations and/or other changes required to and within the
Premises (after the initial construction of same), whether capital in nature or
non-capital in nature, shall be the responsibility of Tenant and at its cost and
expense; unless the changes are structural in nature and result from the
original design of the Building, in which instance they shall be the
responsibility of Landlord and at its cost and expense.
 
Each party hereto shall indemnify and hold harmless the other party from any and
all liability, loss, cost or expense arising as a result of a party not
fulfilling its obligations as to compliance with the ADA as set forth in this
Section 47.
 
48.   Several Liability. If Tenant shall be one or more individuals,
corporations or other entities, whether or not operating as a partnership or
joint venture, then each such individual, corporation, entity, joint venturer or
partner shall be deemed to be both jointly and severally liable for the payment
of the entire rent and other payments specified herein.
 
49.  Financial Statements. Tenant represents and warrants to Landlord that the
financial statements heretofore delivered by Tenant to Landlord are true,
correct and complete in all respects, have been prepared in accordance with
generally accepted accounting principles, and fairly represent the financial
condition of Tenant as of the date thereof, and that no material change has
thereafter occurred in the financial conditions reflected therein. Within
fifteen (15) days after request from Landlord, Tenant agrees to deliver to
Landlord such future financial statements and other information as Landlord from
time to time may reasonably request.
 
50.   Definition of "Day" and "Days" . As used in the Lease, the terms "day" and
"days" shall refer to calendar days unless specified to the contrary; provided,
however, that if the deadline established for either party's performance
hereunder occurs on a Saturday, Sunday or banking holiday in the State of
Maryland, the date of performance shall be extended to the next occurring
business day.
 
IN WITNESS WHEREOF, Landlord and Tenant have respectively affixed their hands
and seals to this Lease as of the day and year first above written.

WHEREAS, by a certain lease between Landlord and Tenant dated as of , 2001
(together with all amendments, options, extensions and renewals, the "Lease"),
Landlord has demised to Tenant all or a portion of the Real Property; and
 
WHEREAS, as a condition to making the Loan, Landlord assigned its interest in
the Lease to Lender as part of Lender's security; and
 
WHEREAS, the Tenant's execution and delivery of this Agreement and of an
estoppel certificate providing the Lender with current information on the status
of the Lease (the "Estoppel") are conditions precedent to Lender's obligation to
fund the Loan; and
 
WHEREAS, Tenant desires to enter into this Agreement in order to benefit from
the promises by Lender that are set forth in this Agreement;
 
NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants
herein contained, the parties agree as follows:
 

1.  
If, upon the closing of the Loan, the Lease would not by its terms be
subordinate to the lien of Lender on the Real Property, Tenant so subordinates
the Lease.

 
2.  The Tenant consents to the assignment of the Lease to Lender in support of
the Loan.
 

3.  
If Landlord defaults under the Lease and, upon notice, fails to cure its default
within the cure period provided under the Lease, Tenant will notify Lender of
the default and afford Lender a reasonable opportunity to cure it before
terminating the Lease or exercising any self-help rights from which a right of
setoff would arise.

 

4.  
If Lender forecloses the Loan or acquires title to the Real Property by deed in
lieu of foreclosure, the following terms and conditions will govern the
respective rights and obligations of Tenant and Lender or other new owner of the
Real Property (in either case, the "New Owner"):

 

(a)  
The New Owner shall not disturb Tenant's quiet enjoyment and possession of its
demised premises for so long as Tenant faithfully performs its obligations under
the Lease and under this Agreement.

 

(b)  
The New Owner shall not be bound by any purchase option contained in the Lease.

 

(c)  
The New Owner shall not be required to assume any of Landlord's liabilities to
Tenant under indemnification or hold harmless agreements in the Lease arising
from any Landlord default, act or omission occurring prior to the date New Owner
acquires title to the Real Property, or for damages caused by any Landlord
default, act or omission occurring prior to date New Owner acquires title to the
Real Property, and, following the acquisition of title, the New Owner's
liability to the Tenant shall never exceed the value of the New Owner's interest
in the Real Property.

 
 

(d)  
This Agreement will not vary the terms of the Lease that condition Tenant's
obligation to pay rent on Landlord's performance of its covenants under the
Lease in respect of the habitability and quiet enjoyment of the Real Property,
which Lender agrees shall apply to the New Owner as they have to the
Landlord,provided Tenant has performed its obligation under paragraph 3 of this
Agreement.

 
            (f)  Subject to the other terms of this Agreement, Tenant will, upon
notice of the transfer, attorn to the New Owner (that is, recognize the New
Owner as the landlord under the Lease from the time of transfer of the Real
Property forward).
 
                    (g) The New Owner will not be bound by any modification of
the Lease made without Lender's consent. The New Owner will not be bound by any
rent paid more than one month in advance unless it actually receives it, or
unless Lender has consented to the advance payment in writing.
 

(h)  
In respect of security or other lease deposits it receives, the New Owner shall
be bound under the terms of the Lease.

 
The New Owner will be bound by offset rights under the Lease that have arisen
through the Tenant's exercise of its rights to cure Landlord defaults, but only
if
the Tenant has performed its obligations under paragraph three of this Agreement
and the default has remained uncured.
 

5.

by the party against whom enforcement is sought.
