2.         Demise and Measurement of Premises.  Landlord hereby leases unto
Tenant, and Tenant does hereby rent from Landlord the Premises that will be
constructed in accordance with the provisions of Section 35 of this Lease.  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, if any, the Common Areas
of the Building (as that term is defined in Section 6.2.4 hereof). The Premises
and the Building shall be measured in accordance with BOMA standards (ANSI
Z65.1- 1996), utilizing the “Gross Building Area” computation. At Tenant’s
election, the Rentable Area of the Building as set forth in Section 1.1.3 shall
be subject to confirmation before the Rent Commencement Date by Tenant’s
architect, at Tenant’s sole cost. In the event the Rentable Area of the Building
figure determined by Tenant’s architect differs by no more than 0.5% (higher or
lower) from the Rentable Area of the Building set forth in Section 1.1.3 , then
the Rentable Area of the Building set forth in Section 1.1.3 shall be
controlling.  In the event the Rentable Area of the Building figure determined
by Tenant’s architect differs by more than 0.5% (higher or lower) from the
Rentable Area of the Building set forth in Section 1.1.3, then Landlord and
Tenant (in coordination with their respective architects) shall endeavor in good
faith to resolve the discrepancy, and in the event they are not able to resolve
such discrepancy then Landlord and Tenant shall jointly appoint an independent
architect to resolve such discrepancy within thirty (30) days following a
request therefor by Landlord or Tenant and the determination of such independent
architect shall be binding on both Landlord and Tenant.  During any such
dispute, Tenant shall pay Annual Base Rent to Landlord based on the Rentable
Area of the Building set forth in Section 1.1.3.  If such independent architect
determines that the rentable area differs by no more than 0.5% from the Rentable
Area of the Building set forth in Section 1.1.3, then the fees of such
independent architect shall be borne by Tenant, otherwise such fees shall be 
borne by Landlord.  Promptly after determination of the Rentable Area of the
Building in accordance with this Section 2, Landlord and Tenant shall execute an
amendment to this Lease confirming such determination and with a proportionate
adjustment to Annual Base Rent, additional rent and any prior payments which
have been made by Tenant.  In no event shall Tenant be required to pay Annual
Base Rent based on more than  157,514 rentable square feet regardless of the
actual measurement of the rentable square footage of the Premises.  Landlord
shall have no right to remeasure the Premises during the Term.  In the event
Tenant does not elect to verify the Rentable Area of the Building pursuant to
this Section 2, then the Rentable Area of the Building shall be as set forth in
Section 1.1.3. 

            3.         Term.

            3.1       Commencement Date and Term.  All of the provisions of this
Lease shall be in full force and effect from and after the Effective Date. As
used in this Lease, the term “Commencement Date”, as advanced or postponed
pursuant to the terms hereof, shall be defined as the date of Delivery of
Possession of Landlord Items (as defined in Section 35) and, subject to Section
35.1 hereof, the term “Rent Commencement Date” shall be the date which is one
hundred fifty (150) days following that date of Delivery of Possession of
Landlord’s Items (as defined in Section 35).  Notwithstanding the foregoing to
the contrary, if Tenant elects for Landlord to construct the Tenant’s Work
pursuant to the terms of Section 35 below, the Commencement Date and the Rent
Commencement Date shall be the date of Delivery of Possession of the Premises
with Landlord’s Work substantially completed.  The first Lease Year shall
commence on the Commencement Date and shall end on the date which is last day of
the calendar month which is twelve (12) full months after the Rent Commencement
Date. Within fifteen (15) days after receipt of a written request from Landlord,
Tenant shall execute and deliver the Commencement Date Agreement in
substantially the form attached hereto as Exhibit “F”.

            3.2       Option to Extend Lease Term.  Provided Tenant is not in
default of any term, covenant or condition of this Lease beyond any applicable
notice and cure period, Tenant shall have the option to extend the Initial Term
of this Lease for the entire Premises for three (3) additional periods of five
(5) years each (the “Renewal Term”) to commence immediately upon the expiration
of the Initial Term, the First Renewal Term and the Second Renewal Term, as
applicable.

            Tenant’s rental of the Premises during the First Renewal Term, the
Second Renewal Term and the Third Renewal Term, as applicable, shall be upon the
same terms, covenants and conditions contained in this Lease, except that Tenant
shall pay to Landlord as Annual Base Rent that amount equal to the “Prevailing
Market Rate” for the Premises for the First Renewal Term, the Second Renewal
Term and the Third Renewal Term, as applicable, as hereinafter defined
(including annual adjustments).  For purposes of this Section 3.2, the term
“Prevailing Market Rate” shall mean the then prevailing market rate being
charged for renewals of comparable space in comparable office buildings within a
ten (10) mile radius of the Premises, with consideration given for all factors
appropriately considered in determining fair market economics of a similar
transaction, including, but not limited to, construction allowances, commissions
(or lack thereof), free rent, the creditworthiness of Tenant and other
concessions or premiums, costs being saved and downtime for vacancy.  In order
to exercise its option granted herein, Tenant shall notify Landlord in writing
of its intent to renew not less than three hundred sixty-five (365) days prior
to the expiration of the Initial Term, the First Renewal Term or the Second
Renewal Term, as applicable.  Within thirty (30) days following the exercise by
Tenant of its option to extend the Lease for the First Renewal Term, the Second
Renewal Term and the Third Renewal Term, as applicable, Landlord shall notify
Tenant in writing of its determination of the Prevailing Market Rate for the
First Renewal Term, the Second Renewal Term and the Third Renewal Term, as
applicable, as reasonably determined by Landlord (“Landlord’s Notice”).  Within
ten (10) business days after receipt of Landlord’s Notice, Tenant shall notify
Landlord in writing of Tenant’s acceptance or rejection of such rate.  If Tenant
accepts the proposed Prevailing Market Rate by written notice to Landlord,
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 does not accept the proposed
Prevailing Market Rate as determined by Landlord for the First Renewal Term, the
Second Renewal Term and the Third Renewal Term, as applicable, 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 for either the First Renewal Term, the Second
Renewal Term or the Third Renewal Term, 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 have the right to notify Landlord within ten (10) business  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), that it rejects such Prevailing Market Rate and in such event,
Tenant’s option to extend the Lease for the First Renewal Term, the Second
Renewal Term or the Third Renewal Term, as applicable, shall be void and
inoperable.  If Tenant fails to exercise its right to reject the Prevailing
Market Rate, then 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.  Landlord and Tenant shall each pay the fee of the
broker designated by them originally and shall split the fees of the Third
Broker.  If Tenant shall fail to deliver the requisite notice exercising its
option to extend by the date prescribed above, then Tenant’s option to extend
the Term for the First Renewal Term, the Second Renewal Term and the Third
Renewal Term, as applicable, shall be void and inoperable.  The Second Renewal
Term and the Third Renewal Term shall terminate if Tenant does not elect to
renew the Lease for the First Renewal Term.  The Third Renewal Term shall
terminate if Tenant does not elect to renew the Lease for the Second Renewal
Term.

            3.3       Definition of “Term”.  As used herein, the word “Term”
shall refer to the Initial Term the First Renewal Term, the Second Renewal Term
and the Third Renewal Term, if applicable. 

            4.         Security Deposit and Advance Rent.

            4.1       Security Deposit.  Simultaneously with the execution of
this Lease, Tenant shall not be required to pay a Security Deposit in accordance
with the terms of this Lease.  However, if prior to the Rent Commencement Date,
Tenant’s credit rating falls below a “BB-” as determined by Standard & Poor’s
credit rating agency or Moody’s credit rating agency, Tenant shall pay to
Landlord a Security Deposit in the amount of  $1,998,307.50 by Letter of Credit
(as further described below) as security for the performance by Tenant of all
obligations imposed on Tenant hereunder.  Tenant shall deliver to Landlord a
statement of its credit rating on each January 15, April 15, July 15, and
October 15th occurring after the Effective Date and prior to the Rent
Commencement Date; provided, however, that the provisions of the immediately
proceeding sentence shall be effective at anytime prior to the Rent Commencement
Date and shall not be limited to the reporting periods aforementioned.  Tenant
shall deliver the Letter of Credit within fifteen (15) days after written
request from Landlord.  Failure to deliver such Letter of Credit shall be an
automatic Event of Default under the terms of the Lease, without further notice
or cure periods afforded to Tenant.

            In such event, Tenant shall deliver to Landlord an unconditional and
irrevocable Letter of Credit issued by and drawable upon Comerica Bank in San
Diego, California or another banking institution reasonably approved by Landlord
in the amount of  $1,998,307.50 to be held by Landlord as a guaranty for the
payment and performance by Tenant of all covenants and obligations of Tenant as
set forth in this Lease.  The Letter of Credit shall contain terms whereby it
can be drawn on by Landlord by sending the original Letter of Credit by
overnight delivery, in the case of an institution which is not located in the
Baltimore-Washington metropolitan area or  on sight if located in the
Baltimore-Washington metropolitan area on any date during the Term of this Lease
on which issuer shall receive from Landlord a certification signed by Landlord
stating that there is a Event of Default by Tenant under the terms of this
Lease. Landlord shall have the right to make such certification immediately upon
any Event of Default by Tenant hereunder (as defined in Section 21 hereof) and
to apply said sum against all amounts then due and owing by Tenant hereunder
and/or against sums required to be and actually expended by Landlord hereunder
to correct existing defaults by Tenant.  The Letter of Credit shall also provide
that Landlord shall have the right to draw upon the Letter of Credit, in full or
in part.  Any balance left of the sum received from drawing on the Letter of
Credit, after the correction of defaults by Tenant and/or the payment of amounts
due by Tenant, shall be credited against the next Rent payment(s) due to
Landlord.  In the event Landlord shall draw on the Letter of Credit provided by
Tenant, all as set forth herein, Tenant shall replace same no later than thirty
(30) days after the date of such drawing, and if same is not replaced, it shall
constitute an Event of Default 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.

            Subject to the provisions of Section 4.1.1 below, Tenant
acknowledges and agrees that it shall keep the Letter of Credit in full force
and effect throughout the Term of this Lease.  In the event the term of the
Letter of Credit is not coterminous with the Term of this Lease, then not more
than forty-five (45) days prior to any expiration date of the Letter of Credit,
Tenant shall provide Landlord with the appropriate documentation that said
Letter of Credit has been extended and provide Landlord with the new expiration
date of same.  Should Tenant fail to provide Landlord with such documentation on
or before the expiration date of the Letter of Credit, Landlord shall have the
right to draw on the entire amount of said Letter of Credit and hold it without
interest for the benefit of Landlord as security for the faithful performance of
the Lease until the Letter of Credit is reinstated or the Term of the Lease
expires.  If the Letter of Credit is not reinstated, the amount drawn by
Landlord shall be returned to Tenant, less all costs incurred by Landlord in
correcting or satisfying any Event of Default under this Lease within thirty
(30) days after the expiration or earlier termination of the Term.

            No right or remedy available to Landlord as provided in this Section
4.1 shall preclude or extinguish any other right or remedy to which Landlord may
be entitled.

            Notwithstanding the foregoing, if the Letter of Credit is required
and Tenant then receives a rating of  “BB” or higher by Moody’s for twelve (12)
consecutive months, then Landlord shall return the Letter of Credit to Tenant
and Tenant shall have no further obligation to pay a Security Deposit during the
Term.

                        4.1.1    Transfer.  Upon a sale of the Land and/or the
Building or a leasing of the Building, or any financing of Landlord’s interest
therein, Landlord shall have the right to transfer any cash Security Deposit or
the Letter of Credit, as applicable, to the vendee, lessee or lender, provided
such vendee, lessee or lender assumes Landlord’s obligations hereunder with
respect to the cash Security Deposit or the Letter of Credit, as applicable. 
With respect to the Letter of Credit, within ten (10) business days after notice
of such sale, leasing or financing, Landlord (with Tenant’s cooperation), at its
sole cost, shall arrange for the transfer (by amendment) of the Letter of Credit
to the new landlord or the lender, or have the Letter of Credit reissued in the
name of the new landlord or the lender.  To the extent so transferred, Tenant
shall look solely to the new landlord or lender for the return of such cash
Security Deposit or Letter of Credit and the provisions hereof shall apply to
every transfer or assignment made of the Security Deposit to a new landlord. 

                        4.1.2    Reduction.

                                    (a)        Provided no uncured Event of
Default shall then exist, then on the first day of each Lease Year, commencing
with the first day of the sixth (6th)      Lease Year, and continuing annually
thereafter on the first day of each subsequent Lease Year in which Tenant
qualifies for reduction (each such anniversary date, a “Reduction Date”), Tenant
shall have the right to reduce the Security Deposit (a “Reduction”) to the
amount set forth in the following schedule (the “Reduction Schedule”):

                            Reduction Date                              Amount

                            First Day of Lease Year #6                  
$1,665,256.25

                            First Day of Lease Year #7                  
$1,332,205.00

                            First Day of Lease Year #8                   $  
999,153.75

                            First Day of Lease Year #9                   $  
666,102.50

                            First Day of Lease Year #10                 $   
333,051.25        

                                    (b)        Provided Tenant qualifies as of
any such Reduction Date, such Reduction shall be effectuated by Tenant’s
delivery of either (i) a replacement letter of credit for the applicable lesser
amount, which replacement letter of credit may (A) include an endorsement that
provides that such replacement Letter of Credit shall be effective only upon
Landlord’s return of the Letter of Credit being replaced or Landlord’s written
consent to cancellation of the letter of credit being replaced, or (B) be
delivered pursuant to an escrow arrangement otherwise reasonably approved by
Landlord and Tenant, or (ii) at least ten (10) business days prior to the
effective date of such Reduction, a written amendment to the Letter of Credit
which has the effect of reducing the amount of the Letter of Credit to the
lesser amount determined pursuant to this Section as of the applicable Reduction
Date.

                                    (c)        If Tenant does not qualify for a
Reduction as of any applicable Reduction Date, but Tenant subsequently does
qualify for such Reduction as of a later Reduction Date, then Tenant shall be
permitted to “catch up” all prior foregone Reductions as of the applicable
Reduction Date.  (For example, if Tenant had never previously qualified for a
Reduction, but did so effective as of the Reduction Date coinciding with the
first day of Lease Year #8, then the Security Deposit would be reduced from 
$1,998,307.50 to  $999,153.75 as of such Reduction Date.)

            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 Annual Base Rent payable by Tenant hereunder.

            5.         Use.  Tenant covenants that it shall use and occupy the
Premises during the Term of this Lease solely for general office purposes and
uses incidental and ancillary thereto that are consistent with the operation of
a Class A office building which uses may include, without limitation, data
center, SCIF, training, employee/building invitee cafeteria/in-house food
service, operations center, coffee and vending uses, Tenant company store, deli,
light assembly for modification and testing of computers and related equipment,
child care for employees, exercise facility and conference center, all in
accordance with applicable zoning regulations. 

            6.         Rent.

            6.1       Annual Base Rent.  As rent for the Premises during each
year of the Term, commencing on the Rent Commencement Date, 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 1.1.6 above.  In
addition, if the Rent Commencement Date occurs on a day other than the first day
of a calendar month, Tenant shall pay to Landlord upon the Rent Commencement
Date, a sum equaling that percentage of the monthly rent installment which
equals the percentage of such calendar month falling after the Rent Commencement
Date. 

            Notwithstanding the foregoing, Tenant shall have the right to abate
a portion of the Annual Base Rent up to a maximum amount of either (i) 
$333,051.25 per month over the first three (3) months of the Term, computed as
($25.50 x 156,730)/12, or (ii)$166,525.63 per month over the first six (6)
months of the Term, computed as  [($25.50 x 156,730)/12] divided by 2.  Tenant
shall notify Landlord in writing on or before January 1, 2004, of the amount of
Annual Base Rent, if any, which  Tenant desires to abate and over what period of
time.  If  Tenant fails to notify Landlord of its election to abate Annual Base
Rent on or before January 1, 2004, Tenant shall be deemed to have waived its
right to abate Annual Base Rent.  If Tenant elects option (i), the Annual Base
Rent for the 117 months remaining in the Initial Term shall be increased monthly
by an amount equal to the quotient of the amount abated divided by 117 months;
and if Tenant elects option (ii), the Annual Base Rent for the 114 months
remaining in the Initial Term shall be increased monthly by an amount equal to
the quotient of the amount abated divided by 114 months.  By way of example, but
without limitation, if Tenant elects to abate  $333,051.25 per monthover the
first three (3) months of the Initial Term, Annual Base Rent shall increase
monthly commencing on the 4th month and through the balance of the Initial Term
in an amount equal to $2,846.59, computed as $333,051.25 divided by 117.    If
Tenant elects to abate Annual Base Rent pursuant hereto, (i) within fifteen (15)
days after request from Landlord, the parties shall enter into an amendment to
the Lease which sets forth the revised schedule of Annual Base Rent, and (ii) in
no event shall Tenant’s obligation to pay for electrical service during such
abatement period be abated in any regard.

the Premises were originally constructed; and

                                    6.2.2.12  All other expenses which under

maintaining, operating, or re­pairing the Property.  Notwithstanding the

through 11 of this Section 6.2.2) which would be considered capital in nature
under generally accepted accounting principles shall be included in Building

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 Building, 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
Property, then the charge to Landlord resulting from such altered additional
method of taxation shall be deemed to be within the definition of
“Taxes,”provided that any tax, assessment, levy, imposition or charge imposed on
income from the Premises shall be calculated as if the Premises were the only
asset of Landlord. 

            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, sidewalks, exterior elements, washrooms,
and elevators.  The foregoing notwithstanding, during any period in which Tenant
is leasing (A) 100% of the Building, Tenant shall have the exclusive right to
use the interior Common Areas, and priority usage of the exterior Common Areas,
and (B) 100% of any floor of the Building, Tenant shall have the exclusive right
to use the interior Common Areas on such Floor.  Notwithstanding any other
provision in this Lease to the contrary, during any period in which Tenant is
leasing 100% of the Building, Landlord shall not take any action that will
materially and adversely diminish Tenant’s ability to use the Common Areas
(other than repairs or other obligations which are Landlord’s responsibility
under the terms of Section 11.2 of this Lease) without first obtaining Tenant’s
prior approval (which approval shall not be unreasonably withheld, conditioned
or delayed and shall not be required in the event of an emergency). Without
limiting the foregoing, if, with Tenant’s approval, Tenant’s use of the Common
Areas (including, without limitation, the parking areas) is temporarily
restricted, Landlord shall use all reasonable efforts to minimize the
disturbance to Tenant and the operation of Tenant’s business and to maintain the
confidential nature of Tenant’s business.

                        6.2.5    “Lease Year” shall mean for the first Lease
Year  that period which shall commence on the Commencement Date and shall end on
the date which is last day of the calendar month which is twelve (12) full
months after the Rent Commencement Date and each succeeding twelve (12) month
period thereafter up to the end of the Term.

                        6.2.6    Building Expenses Exclusions.

understood that no expense shall be charged more than once (whether directly or
in Building Expenses). Landlord shall equitably prorate bills for services
rendered to the Building and to any other property owned by Landlord.  Landlord
shall diligently and in good faith pursue all insurance, breach of warranty or
other claims or actions that might result in a reduction in Building Expenses

            6.3       Rent Adjustments for Taxes.

                        6.3.1    On or before March 31 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 tax year
shall be totaled and such total shall be divided by the total rentable square
feet in the Building thereby deriving the “Cost of Taxes Per Square Foot” of
rentable area.  Notwithstanding the foregoing, if Taxes are not fully assessed
against the Property during the Base Year for Taxes, the Base Year for Taxes
shall be deemed to be the full assessed value of the Taxes for a twelve (12)
month period.  Notwithstanding anything herein to the contrary, in no event
shall Tenant be required to pay any additional rent for Taxes for the first
twelve (12) months after the Building has been fully assessed.

                                6.3.2    In the event that the Cost of Taxes Per
Square Foot assessed for any calendar year  after calendar year 2005 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 the number 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, together with reasonably adequate
documentation sufficient to support the amount requested to be paid pursuant to
the invoice after Tenant fully occupies the Building.  For Tenant's obligation
for such addi­tional rent at the end of the Lease, see Section 6.5.  No later
than fifteen (15) days prior to the start of each calendar year after the Base
Year Taxes are determined, Landlord will deliver to Tenant its reasonable
estimate of such additional rent with respect to Taxes, and require Tenant to
pay each month, in advance, during such year 1/12 of such amount, at the time of
payment of monthly installments of Base Rent.  Tenant shall have the right to
examine, at Tenant's sole expense, Landlord's records with respect to any such
increases in rent; provided, however, that unless Tenant shall have given
Landlord written notice of exception to any such statement within thirty (30)
days after delivery thereof, the same shall be conclusive and binding on Tenant
for the applicable year, subject to Tenant’s audit rights.     If Landlord has
not delivered the estimate of Taxes  to Tenant by the first day of January of
the applicable calendar year, Tenant will continue paying Tenant’s Share of 
Taxes based on the Tax  estimate for the previous calendar year until the new
estimate of Taxes is delivered.  No credit shall be given to Tenant if the Cost
of Taxes Per Square Foot are less than the Base Year Taxes.

                        6.3.3    Landlord’s Right to Contest Property Taxes. 
Landlord is not obligated to but may contest the amount or validity, in whole or
in part, of any Taxes.  Landlord’s contest will be at Landlord’s sole cost and
expense, except that if Taxes are reduced (or if a proposed increase is avoided
or reduced) because of Landlord’s contest, Landlord may include in its
computation of Taxes the costs and expenses Landlord incurred in connection with
the contest, including, but not limited to, reasonable attorney’s fees, up to
the amount of any Tax reduction Landlord realized from the contest or any Tax
increase avoided or reduced in connection with the contest, as the case may be.

                        6.3.4    Tenant’s Right to  Request Landlord to Obtain a
Reduction in Assessments.  Tenant may request in writing that Landlord, from
time to time, but no more often than once every two (2) years during the Term,
endeavor to obtain a reduction in the assessed valuation of the Building for the
purpose of reducing Taxes.  In such event, Landlord shall use commercially
reasonable efforts to effect such a reduction.  Landlord shall have sole control
and discretion in its efforts to obtain such reduction in assessments.  Landlord
shall credit against Taxes any tax refund payable as a result of any proceeding
instituted pursuant to this Section 6.3.4.  In the event Landlord is successful
in obtaining such reduction in the assessed valuation of the Building, all
reasonable costs and expenses incurred by Landlord in such endeavor shall be
included in Taxes up to the amount of any tax refund payable.  To the extent the
costs of such proceedings exceed any tax refund or in the event such proceedings
are unsuccessful, all such reasonable costs and expenses incurred by Landlord
shall be Tenant’s sole responsibility and shall be charged to Tenant as
additional rent.  Tenant shall be entitled to the refund of any excess Taxes
attributable to Taxes, penalties, fines and interest thereon received by
Landlord which has been paid by Tenant or which has been paid by Landlord but
for which Landlord has been previously reimbursed in full by Tenant, such amount
to be paid within thirty (30) days after receipt by Landlord.

            6.4       Rent Adjustments for Building Expenses.

                        6.4.1    On or before March 31 of each Lease Year,
Landlord shall compute the Building Expenses for such 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 deriving the “Cost of Building Expenses
Per Square Foot” of rentable area.

                        6.4.2    In the event that the cost of Building Expenses
Per Square Foot of rentable area for any year after calendar year 2005 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.   If, during any year that Tenant is not leasing 100%
of the Building,  occupancy of the Building during any calendar year is less
than one hundred percent (100%), 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 one hundred percent (100%) 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.   
Notwithstanding the provisions of Section 1.1.11, in the event Tenant does not
fully occupy the Building during the entire Base Year for Building Expenses,
then the Base year for Building Expenses shall be the first twelve (12) calendar
months that Tenant fully occupies the Building, provided that if Tenant does not
fully occupy the Building within eighteen (18) months after the Commencement
Date, the Base Year Building Expenses shall be grossed up using the last twelve
(12) months of the eighteen (18) month period.  Such additional rent shall be
computed on a year-to-year basis.  No later than fifteen (15) days prior to the
start of each calendar year, Landlord will deliver to Tenant its reasonable
estimate of such additional rent with respect to Building Expenses, and require
Tenant to pay each month, in advance, during such year 1/12 of such amount, at
the time of payment of monthly installments of Base Rent.  Tenant shall have the
right to examine, at Tenant's sole expense, Landlord's records with respect to
any such increases in  Building Expenses; provided, however, that unless Tenant
shall have given Landlord written notice of exception to any such statement
within thirty (30) days after delivery thereof, Tenant shall pay the same for
the balance of the year, subject to Tenant’s audit rights.     If Landlord has
not delivered the estimate of Building Expenses  to Tenant by the first day of
January of the applicable calendar year, Tenant will continue paying Tenant’s
Share of  Building Expenses based on the Building Expense  estimate for the
previous calendar year until the new estimate of Building Expenses is delivered.
Tenant shall pay any additional rent owed as a result of increased Building
Expenses within thirty (30) days after delivery thereof, the same shall be
conclusive and binding on Tenant for the applicable year, subject to Tenant’s
audit rights.  Any such additional rent shall be due within thirty (30) days
after Landlord has submitted a written state­ment to Tenant showing the amount
due.    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.

                        6.4.3    Tenant shall have the right to (i) provide its
own janitorial services to all or any portion of the Premises, and/or (ii)
require modifications to the standard office janitorial service as described in
Exhibit “J” hereto.  If Tenant chooses to provide and/or modify such services,
Landlord and Tenant shall enter into an amendment to this Lease which reduces or
increases, as the case may be, the Annual Base Rent due hereunder from the date
Tenant provides such services or requires such modifications, as the case may be
by the amount of any savings or increased cost and adjusts the Base Year
Building Expenses proportionately.  Landlord and Tenant acknowledge and agree
that the cost included in the stated Annual Base Rent for standard unescorted,
after-hours  janitorial services is Eighty Cents ($0.80) per rentable square
foot.

            6.5       Additional Rent Payments.  Tenant’s obligation to pay any
additional rent 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  ends, for the portion of 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
for one (1) year.

            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, 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 ten (10) calendar days after
written notice that such payment is past due (provided, that in no event shall
Landlord be required to give more than two (2) written notices in any twelve
(12) month period) , 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 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 15% 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 $50.00 for each such check
returned for insufficient funds.  Time is of the essence in this Lease. No
invoice, nor any request for unscheduled additional rent, shall be sufficient
unless accompanied by receipts or other reasonably adequate documentation
sufficient to support the amount requested to be paid pursuant to the invoice. 

            6.7       Annual Taxes and Building Expense Statement.  From and
after the Rent Commencement Date, after the end of each calendar year, Landlord
shall submit to Tenant a statement prepared by Landlord’s property management
company  (the “Taxes and Building Expense Statement”) setting forth in
reasonable detail the Taxes and Building Expenses for such calendar year and the
amount (if any) of Tenant’s Share of Building Expenses and Taxes for such
calendar year.  If Tenant’s Share of the Building Expenses and Taxes so stated
is more than the amount (if any) theretofore paid by Tenant for Building
Expenses and Taxes for the period covered by the Taxes and Building Expense
Statement, Tenant shall pay to Landlord the deficiency within thirty (30) days
after the submission of the Taxes and Building Expense Statement.  If Tenant’s
Share of the Building Expenses or Tenant’s Share of Taxes so stated is less than
the amount (if any) theretofore paid by Tenant for Building Expenses or Taxes
for the period covered by the Taxes and Building Expense Statement, Landlord
shall credit the excess against the next monthly installment of Annual Base Rent
thereafter payable by Tenant under this Lease, except that Landlord shall refund
the excess (if any) for the calendar year ending with or within the last Lease
Year to Tenant within forty-five (45) days after submission of the Taxes and
Building Expense Statement for such calendar year.  Tenant’s obligation under
this subsection to pay Tenant’s Share of Building Expenses and Taxes and
Landlord’s obligation to reimburse Tenant for any overpayment shall survive the
expiration of the Term or the earlier termination of this Lease for one (1)
year.

            6.8       Disputes.  Each statement of Taxes and Building Expenses 
shall be in a form sufficiently detailed and complete for Tenant’s adequate
review, sent to Tenant shall be conclusively binding upon Tenant unless Tenant
shall (i) within thirty (30) days after such  statement is sent, pay to Landlord
the amount set forth in such statement, without prejudice to Tenant’s right to
dispute such  statement, and (ii) within one hundred  eighty (180) days after
such  statement is received, give notice to Landlord objecting to such 
statement and specifying the reasons that such  statement is claimed to be
incorrect. No such objection shall prejudice Tenant’s right to make further
objections with respect to the same             statement within the permitted
time periods.  Tenant shall have the right at its sole cost and expense to
review or audit Landlord’s books and records relating to Landlord’s calculation
of Building Expenses and Taxes at any time within two years from Tenant’s
receipt of the statement, and may use the auditor or reviewer of its choice
provided such auditor’s area of expertise includes lease expense analysis.  If
the parties are unable to resolve a dispute as to the correctness of a 
statement within thirty (30)  days following Tenant’s notice of objection,
either party may refer the issues raised to an accountant reasonably acceptable
to the other party and that has not and does not provide accounting and
consulting services to Landlord or Tenant and does not otherwise have any
affiliation or business relationship with Landlord or Tenant, and the decision
of such accountants shall be conclusively binding upon Landlord and Tenant. The
fees and expenses relating to the accountant hired to conclusively resolve the
dispute as to the correctness of the statement shall be borne by the
unsuccessful party (and if both parties are partially unsuccessful, the
accountants shall apportion the fees and expenses between the parties based on
the degree of success of each party).  In the event there is an adjustment of
the statement, the amount owed by either party shall be increased by interest on
the sum owed calculated at  the Default Rate from the date of the original
payment until the date the adjustment is paid

            7.         Requirements of Applicable Law.  Landlord warrants that
on the Commencement Date, the Premises shall comply with the Association
Declaration and all applicable Federal, State and local laws, codes, ordinances,
rules and regulations of governmental authorities having jurisdiction over the
Property, including, but not limited to, zoning rules and regulations and the
Americans with Disabilities Act (“Applicable Laws”).  Tenant, at its sole cost
and expense, shall comply promptly with all Applicable Laws first enacted after
the Rent Commencement Date, 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 are being used for a purpose which is in violation of such certificate
of occupancy, permit, or consent, then Tenant shall, upon five (5) days’ notice
from Landlord, immediately discontinue such use of the Premises.  If thereafter
the governmental authority asserting such violation 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. 

            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 Applicable Laws 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, 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.  

            10.1     Except to the extent that Landlord is responsible for
making improvements to the Premises pursuant to Section 35 of this Lease and
subsequent to the installation of Tenant’s Work pursuant to Section 35, Tenant
shall make such improvements to the Premises as it may deem necessary at its
sole cost and expense.   Notwithstanding anything herein to the contrary, Tenant
shall have the right to make non-structural alterations which do not affect the
mechanical, electrical or plumbing systems of the Building without obtaining
Landlord’s prior consent, provided that either (i) such alterations cost less
than Fifty  Thousand Dollars ($50,000.00) per occurrence during the Initial Term
and One Hundred Thousand Dollars ($100,000,00) during any of the Renewal
Term(s), or (ii) are items of decoration, painting or carpeting.   Landlord will
notify Tenant of Landlord’s election to consent or withhold its consent within
ten (10) days after receiving Tenant’s written request for consent to an
alteration.  If Landlord does not respond within such ten (10) day period,
Landlord shall be deemed to have given consent to the proposed alteration.
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, installations, additions or improvements made by either of the
parties hereto upon the Premises, (except for Tenant’s movable office fixtures,
furniture and equipment, trade fixtures, generators, uninterruptible power
sources,  supplemental HVAC equipment in addition to the base building systems,
and other items identified by Tenant prior to the Rent Commencement Date or,
after the Rent Commencement Date, as mutually agreed upon in writing,
collectively, “Tenant’s Personal Property”), 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.  Except for Tenant’s Personal
Property, Tenant shall have no obligation to remove any improvements to the
Premises, made by or on behalf of Tenant, including, without limitation, the
Tenant’s Work.  If Tenant fails to remove any of Tenant’s Personal Property
items, Landlord shall have the right, but not the obligation, to remove and
dispose of such items, and restore the Premises accordingly and Tenant shall
reimburse Landlord for the costs of such removal, disposal and restoration
within thirty (30) days after receipt of an invoice therefore, together with
interest at the Default Rate, which shall accrue form the date the costs were
incurred by Landlord.

            10.2         Notwithstanding anything herein to the contrary, within
six (6) months after the expiration or sooner termination of the Term, Landlord,
at Tenant’s expense, shall have the right to remove all of the improvements
comprising the auditorium in the Building and restore the level of the floor of
such area to match the grade of the balance of the first floor area (the
“Restoration Costs”).  In no event shall the Restoration Costs exceed the lesser
of (i) $67,000.00, or (ii) the amount of costs actually incurred by Landlord. 
Tenant shall reimburse Landlord for such costs within thirty (30) days after
receipt of a written invoice for such Restoration Costs, together with
reasonable supporting documentation.  Tenant’s obligations under this Section
10.2 shall survive the expiration or sooner termination of this Lease, unless
the parties have agreed specifically in writing that the provisions of this
Section 10.2 shall be of no further force and effect.  If Landlord fails to
remove such improvements and restore the level of the floor of such area within
the six (6) month period, Tenant shall have no obligation to reimburse Landlord
for the Restoration Costs and the provisions of this Section 10.2 shall be of no
further force or effect.

            11.       Repairs and Maintenance.

            11.1     Tenant’s Care of the Premises and Building.  During the
Term Tenant shall:

                        (i)         keep the Tenant’s Personal Property and the
fixtures, appurtenances and equipment installed on the Premises in good order
and condition, except to the extent such maintenance is the obligation of
Landlord pursuant to Section 11.2;

                        (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)       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 repairs and replacements to the Premises (excluding
items of the Tenant’s Work such as wall coverings, carpeting and the like, but
including extensions of the Base Building Systems, such as additional sprinkler
heads, VAV boxes, supplemental HVAC units, plumbing systems and the like),
Common Areas and the Building (including Building fixtures and equipment) as
shall be reasonably deemed necessary to maintain the Building in a condition
comparable to other newly constructed first class suburban office buildings of
comparable quality in the Baltimore‑Washington corridor area (“Comparable
Buildings”).  If Tenant constructs Tenant’s Work pursuant to the terms of
Section 35, to the extent that Tenant installs items as part of its improvements
that Landlord is responsible to maintain during the Term, Tenant shall transfer
any warranties to Landlord.  Without limiting the foregoing, this maintenance
shall include (a) the roof, foundation, exterior walls and windows (including
interior sprandrel systems and gaskets), interior structural walls, all
structural components (including the foundation), and all systems such as
mechanical, electrical, HVAC and plumbing, (b) all landscaping and parking
areas at the Property (including snow removal and repair);  (c) all other
repairs deemed reasonably necessary for the prudent management of the Premises
or as requested by Tenant.  The costs associated with such repairs shall be
deemed a part of Building Expenses; provided, however, that (i) costs of all of
such repairs which would be considered capital in nature under generally
accepted accounting principles shall be paid by Landlord, (ii) the portion of
the costs which are covered by warranties shall not be included in the Building
Expenses.  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. 
Landlord agrees to diligently attend to any repairs or maintenance needs brought
to its attention by written notice from Tenant as soon as reasonably practicable
(but in no event shall Landlord commence such repairs or maintenance later than
five (5) days (or shorter period as may be reasonably required in an emergency)
thereafter or cease to pursue the completion of such repair with diligence) and
in a commercially reasonable manner calculated to minimize to the extent
possible disruption of Tenant’s business activities.

                        11.2.1  Failure to Repair or Maintain.  If either party
fails within the time periods required by this Lease (or such shorter period as
may be required in an emergency) to proceed with diligence to make any required
repairs or perform any maintenance, the other party may do so and the
non-performing party shall reimburse the performing party for within thirty (30)
days after receipt of a written invoice for all reasonable, out-of-pocket costs
and expenses incurred on account thereof, together with interest at  the Default
Rate from the date that such costs and expenses were incurred.    If Landlord
fails to pay the amounts due in connection with this Section,  Tenant shall have
no rights to offset such amounts against future obligations to pay Annual Base
Rent or additional rent until Tenant has received a final, unappealable,
adjudicatory decision.

                        11.2.2  Interruptions Due to Repairs.

(a)        Landlord shall minimize interference with Tenant’s use and occupancy
of the Premises during the making of any repairs, alterations, additions,
improvements, repairs or replacements, Landlord shall provide Tenant with
reasonable notice of the scope and schedule of any such work and, in the event
that the completion thereof is reasonably likely to disrupt (other than in a de
minimis manner) the operation of Tenant’s business at the Premises, Landlord
shall perform such work during non-business hours.  Except as expressly provided
in this Lease to the contrary, 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.

(b)        Notwithstanding anything to the contrary contained in this Lease, if
Tenant is unable to use the Building (or any portion thereof) for the ordinary
conduct of Tenant’s business due to an interruption of an Essential Service (as
hereinafter defined) resulting from (a)  Landlord’s performance of an
alteration, addition, impairment, repair or replacement to the Premises, or due
to Landlord’s entry into the Premises, or for any other reason within Landlord’s
or its agent’s reasonable control, or (b) any of the causes described in Section
27 hereof, and such condition continues for a period in excess of six (6)
consecutive days after (i) Tenant furnishes a notice to Landlord (the “Abatement
Notice”) stating that Tenant’s inability to so use the Premises (or portion
thereof) is due to such condition, and (ii) Tenant does not actually use or
occupy the Premises (or portion thereof) during such period for the ordinary
conduct of its business, then Annual Base Rent, Taxes and Building Expenses for
such portion of the Building that is both untenantable and unoccupied
(determined based upon the ratio which the square footage of such portion of the
Building, determined using the BOMA Standard bears to the Rentable Area of the
Building) shall be abated on a per diem basis for the period commencing on the
seventh (7th) date after the Essential Service is interrupted and ending on the
earlier of (x) the date Tenant reoccupies such portion of the Premises for the
ordinary conduct of its business, and (y) the date on which such condition is
remedied in all material respects.  “Essential Service” shall mean any of
the service and utilities described in Section 23 hereof. 

            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
except in matters of security and safety in which case the repairs shall be made
as expeditiously as possible (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, Tenant shall surrender the Premises to Landlord in the same broom clean
condition that the Premises were in on the date the Tenant’s Work is
substantially completed 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 Tenant’s
Personal Property and repair any damage to the Premises caused by its 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, 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) insurance of 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) day’s written notice to Landlord or its
designees.  All such policies of in­surance shall be effective as of the date
Tenant occupies the Premises and shall be maintained in force at all times
during the Term of this Lease and all other times during which Tenant shall
occupy the Premises. Any insurance required of Tenant hereunder may be furnished
by Tenant under a blanket policy carried by it, provided that such blanket
policy shall contain an endorsement that names Landlord as an additional
insured, specifically references the Premises, and guarantees a minimum limit
available for the Premises equal to or greater than the insurance amounts
required under this Article. 

            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.  Throughout the Term, Landlord shall
maintain standard All Risk Coverage insurance on the Premises, including the
Base Building Shell, Tenant’s Work and subsequent alterations (but excluding
Tenant Personal Property) insuring against such perils as are normally insured
against by prudent owners of Comparable Buildings for the full replacement value
thereof; provided, however, Landlord shall only be required to maintain
insurance for Tenant’s Work and subsequent alterations to the extent Tenant has
provided Landlord the Construction Documents (as defined in Section 35), the
construction documents for any alteration, and reasonably detailed schedules
satisfactory to Landlord’s insurer, describing the property to be insured. 
Without limitation, such insurance shall include:  (i) insurance on the Building
and other improvements and its property therein against fire and casualty and
other risks as may be included in extended coverage casualty insurance in an
amount equal to full replacement value of the Building, and rent loss insurance
protecting Landlord against abatement or loss of rent in an amount equal to the
rent and additional rent paid by Tenant under this Lease.  Landlord shall
include within the coverage of its fire and extended coverage insurance any
improvements and betterments which may be made on behalf of or paid by the
Tenant to the extent that same are customarily insurable as part of the realty;
(ii) comprehensive general liability insurance with a minimum combined single
limit of liability of $2,000,000 for the protection of the Landlord against all
claims for bodily injury (including death) and for the property damage incurred
in, or about the Premises for which the Landlord is legally liable, in respect
of injury in or about the Premises or death of one or more persons, in respect
of one or more occurrences, and in respect of damage to property and including
all contractual obligations coverage and including actions of the employees,
contractors, subcontractors, invitees, agents and others working on behalf of
the Landlord; (iii) broad boiler and machinery insurance covering property
damage; and (iv) such other insurance as it is or may become customary for
owners of Comparable Buildings to carry for loss of or damage to the property,
or liability arising therefrom.  Such insurance shall be maintained with an
insurance company authorized to do business in the State of Maryland, with a
then current Alfred M. Best Company, Inc. (or if it no longer exists, a
comparable rating service) general policy maker’s rating of A- or better and
financial size category of Class X or higher.  Landlord shall promptly deliver
to Tenant notice of (i) any substitution of such company or companies, and (ii)
any change in their Alfred M. Best Company, Inc. general policy maker’s rating
of any such company or substituted company. The deductible on Landlord’s All
Risk Coverage Insurance shall not exceed One Hundred Thousand Dollars
($100,000.00) or such greater amount as may customarily be accepted from time to
time by prudent owners of Comparable Buildings.  Landlord shall name Tenant as
an additional insured on Landlord’s public liability insurance policy.

            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 Tenant’s
Personal Property 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, provided, that in case of any conflict or inconsistency
between the provisions of this Lease and any of the rules and regulations as
originally promulgated or as supplemented or amended from time to time, the
provisions of this Lease shall control.  Landlord shall have the right, from
time to time, subject to Tenant’s prior consent as long as Tenant leases at
least seventy-five percent (75%) of the Building, to issue additional or amended
rules and regulations regarding the use of the Building, so long as the rules
shall be reasonable, non-discriminatory between tenants, impose no cost on
Tenant, do not reduce any rights of Tenant under this Lease.  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.

            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
by payment, filing of a bond, or otherwise, within thirty (30) 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 thirty (30) days 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 reasonable out of pocket expense incurred by Landlord
including but not limited to any costs, damages and reasonable 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, and (ii) interference with the
light, air, or other incorporeal hereditaments of the Premises.

            18.       Destruction -- Fire or Other Casualty.  In case of 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 to substantially the condition of the Premises prior to the
damage, subject to customary requirements of any mortgage regarding placement of
proceeds into trust, submitting requisitions, etc., 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.  To
the extent that the Premises are rendered untenantable in whole or in part the
rent shall proportionately abate from the date of such casualty.  In the event
the damage shall be so extensive as to render the whole Building untenantable or
not reasonably usable by Tenant for its business purposes, then this Lease, at
the option of Tenant or Landlord, shall be terminated upon written notice 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 either party from any liability such party
to the other arising from such damage or from any breach of the obligations
imposed on such party hereunder, or from any obligations accrued hereunder prior
to such termination.

            In addition, in the event that (a) Landlord fails to notify Tenant
of the estimated time to complete the restoration within thirty (30) days after
the casualty, (b) Landlord estimates that its repairs will take more than  two
hundred seventy (270) days for any areas of the Premises, or (c) Tenant is
actually deprived of the use of all or any substantial portion of the Premises
for a period in excess of   two hundred seventy (270) days for any areas of the
Premises, Tenant shall have the right, by written notice to Landlord to
terminate the Lease as of the date of the casualty, provided that Tenant gives
its notice within (45) days after the date of the casualty in the case of
subparagraph (a) above, within thirty (30) days after receipt of Landlord’s
notice of the estimated time to complete the restoration or repair in the case
of subparagraph (b) above, or within thirty (30) days after failing to meet the
deadline set forth in subparagraph (c) above.  .

            19.       Eminent Domain.

(a)        If all or substantially all of the Building shall be acquired or
condemned for any public or quasi-public purpose, other than on a temporary
basis, this Lease shall terminate and the Term shall end as of the date of the
vesting of title and rent shall be prorated and adjusted as of such date.

(b)        If only a part of the Building shall be acquired or condemned then,
except as hereinafter provided in this Section 19, this Lease and the Term shall
continue in full force and effect, provided that from and after the date of the
vesting of title, the rent shall be equitably reduced to reflect the reduction
of the Premises as a result of such acquisition or condemnation.

(c)        If (i) the part of the Premises so acquired or condemned contains
more than thirty-three percent (33%) of the total area of the Building and such
condemnation lasts for a period of 120 days, or (ii) if, by reason of such
acquisition or condemnation, Tenant no longer has reasonable means of access to
the Premises (including the Building and the parking lot) for more than 120
consecutive days, then Tenant may terminate this Lease by notice to Landlord
given within thirty (30) days following the date upon which Tenant received
notice of such acquisition or condemnation.  If Tenant so notifies Landlord,
this Lease shall end and expire upon the thirtieth (30th) day following the
giving of such notice.  If a part of the Premises shall be so acquired or
condemned and this Lease and the Term shall not be terminated in accordance with
this Section 19 Landlord, at Landlord’s expense, but without requiring Landlord
to spend more than it collects as an award, shall, subject to the provisions of
any mortgage, restore that part of the Premises not so acquired or condemned to
a self-contained rental unit as substantially equivalent as reasonably possible
(with respect to character, quality, appearance and services) to that which
existed immediately prior to such acquisition or condemnation, excluding
Tenant’s Personal Property and Annual Base Rent shall be equitably reduced for
the balance of the Term. 

(d)        Upon any termination of this Lease pursuant to the provisions of this
Section 19, rent shall be apportioned as of, and shall be paid or refunded up to
and including, the date of such termination.  This provision shall survive
expiration or earlier termination of the Lease.

(e)        If all or any part of the Premises is acquired or condemned for less
than 120 days during the Term for any public or quasi-public use or purpose,
Tenant shall give prompt notice to Landlord and the Term shall not be reduced or
affected in any way and Tenant shall perform all of its other obligations under
this Lease, except to the extent prevented from doing so by the condemning
authority, provided that rent shall be proportionally abated for the amount of
time any such part of the Premises is unusable by Tenant and Tenant shall be
entitled to receive any award or payment from the condemning authority for such
use.

            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, any improvements which it may or is required to remove at the end of the
Term of this Lease, and an amount with respect to Tenant’s improvements and
alterations (including those described in Article 35) in excess of the then
unamortized amount (amortized over ten (10) years) of the Allowance and the
Amortized Allowance, and also for any item which shall not, under the terms of
this Lease, be or become the property of Landlord at the termination hereof and
any other amount allowed by law.

            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 (a
“Transfer”) for any of the then remaining portion of the unexpired Term or any
portion of the Premises provided:  (i) the net assets of the assignee or
sublessee (a “Transferee”) shall be sufficient in Landlord’s reasonable
determination to perform its obligations under the proposed assignment or
sublease; (ii) in the event of an assignment, such Transferee shall assume in
writing all of Tenant’s obligations under this Lease; (iii) in the event of a
sublease, such sublease shall in all respects be subject to and in conformance
with the terms of this Lease; and (iv) in all events Tenant continues to remain
liable on this Lease for the performance of all terms, including but not limited
to, payment of all rent due hereunder.  Landlord will notify Tenant of
Landlord’s election to consent or withhold its consent within ten (10) days
after receiving Tenant’s written request for consent to a Transfer.  If Landlord
does not respond within such ten (10) day period, Landlord shall be deemed to
have given consent to the proposed Transfer. If this Lease  is assigned, or if
the Premises or any part thereof  is underlet or occupied by anybody other than
Tenant, Landlord may, after default by Tenant, collect rent from the assignee,
undertenant or occupant and apply the net amount collected to the rent herein
reserved, but no such collection shall be deemed a waiver of this covenant, or
the acceptance of the assignee, undertenant or occupant as tenant, or a release
of Tenant from the further observance and performance by Tenant of the covenants
herein contained. For purposes of the foregoing, a transfer by operation of law
or transfer of a controlling interest in Tenant as same exists as of the date
hereof, shall be deemed to be an assignment of this Lease.  No Transfer,
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.  Landlord’s acceptance of any name
submitted by Tenant, an agent of Tenant, or anyone acting by, through or under
Tenant for the purpose of being listed on the Building directory will not be
deemed, nor will it substitute for, Landlord’s consent, as required by this
Lease, to any Transfer or other occupancy of the Premises by anyone other than
Tenant or Tenant’s employees.  Fifty percent (50%) of any profit or additional
consideration or rent in excess of the Annual Base Rent or additional rent
payable by Tenant hereunder (after taking into account tenant improvements for
the proposed assignee or sublessee, legal fees and leasing commissions,
undepreciated costs of tenant improvements made to the Premises by Tenant (or by
Landlord at Tenant’s request and at Tenants’ expense) in excess of the Allowance
and other costs and expenses Tenant incurs in connection with the Transfer)
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.  All the foregoing
notwithstanding, Tenant shall not enter into any lease, sublease, license,
concession or other agreement for the use, occupancy or utilization of the
Premises or any portion thereof, which provides for a rental or other payment
for such use, occupancy or utilization based in whole or in part on the income
or profits derived by any person or entity from the property leased, used,
occupied or utilized. Any such purported lease, sublease, license, concession or
other agreement shall be absolutely void and ineffective as a conveyance of any
right or interest in the possession, use or occupancy of any part of the
Premises. Any consent by Landlord hereunder shall not constitute a waiver of
strict future compliance by Tenant with the provisions of this Article.

            Notwithstanding the foregoing, without the consent and approval of
Landlord, Tenant shall have the right to Transfer the Premises or any portion
thereof without Landlord’s consent (however, Tenant shall endeavor to provide
prior written notice thereof along with a true and complete copy of the sublease
or assignment document) to (a) any Affiliate of Tenant, (b)any entity in which
or with which Tenant, or its corporate successors or assigns, is merged or
consolidated, in accordance with applicable statutory provisions regarding
merger and consolidation of corporations, or (c) any entity that acquires all or
substantially all of Tenant’s assets or stock or all of the assets of an
operating division of Tenant, 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” means any person or entity that, directly
or indirectly, controls, is controlled by or is under common control with
Tenant.  For purposes of this definition, "control" means possessing the power
to direct or cause the direction of the management and policies of the entity by
the ownership of a majority of the voting interests of the entity. 
Notwithstanding the foregoing, Landlord acknowledges that Tenant intends to
allow individuals (or teams of individuals) working on projects with Tenant,
Tenant’s business invitees and Tenant’s customers to temporarily use and occupy
the Premises including, without limitation, employees of third party businesses
whose co-location with Tenant at the Premises facilitates Tenant’s business
operations or its ability to meet its obligations to customers (any of the
foregoing herein call a “Permitted Occupant”).  Provided that such use and
occupancy is subject to all of the terms and conditions of this Lease and
provided that (A) Tenant remains fully liable under this Lease; and (B) the
occupancy arrangement is not a subterfuge by Tenant to avoid its obligations
under this Article 20, then any such occupancy arrangement shall not be deemed
a Transfer under this Section 20 nor be a violation of this Lease.  None of the
foregoing shall prohibit Tenant from recovering an equitable portion of its
costs (including a pro rata portion of Tenant’s rental obligations) from any
Permitted Occupant.

            21.       Default; Remedies; Damages, 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 withdrawn 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 two hundred ten (210) days after the Rent
Commencement Date; 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 written 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) perform, on
behalf and at the expense of Tenant, any obligation of Tenant under this Lease
which Tenant has failed to perform and of which Landlord shall have given Tenant
written notice, the cost of which performance by Landlord, together, with
interest thereon at the Default Rate, from the date of such expenditure, shall
be deemed additional rent and shall be payable by Tenant to Landlord upon
demand; (b) elect to terminate this Lease and the tenancy created hereby by
giving notice of such election to Tenant in which event Tenant shall be liable
for  Base Rent, additional rent, and other indebtedness that otherwise would
have been payable by Tenant during the remainder of the Term had there been no
Event of Default, and on notice reenter the Premises, by summary proceedings or
otherwise remove Tenant and all other persons and property from the Pre­mises,
and store such property in a public warehouse or elsewhere at the cost and for
the account of Tenant, without 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 be liable for any
balance that may be due under this Lease, although Tenant shall have no further
right of possession of the Premises and 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 and (c) exercise any other legal or equitable right or
remedy which it may have at law or in equity.  Notwithstanding the provisions of
clause (a) above and regardless of whether an Event of Default shall have
occurred, Landlord may exercise the remedy described in clause (a) 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 AND/OR CLAIM OF INJURY OR DAMAGE REGARDING THIS LEASE.

            Any reasonable costs and expenses incurred by Landlord (including,
without limitation, reasonable attorneys' fees) in enforcing any of its rights
or remedies under this Lease following an Event of Default, provided that Tenant
shall not be obligated to pay such costs and expenses if it objects in writing
to the validity of the Event of Default, shall be deemed to be additional rent
and shall be repaid to Landlord by Tenant upon demand; and provided further
that, if a formal adjudicatory matter is initiated and there is a final
adjudicatory decision, the non-prevailing party shall pay the reasonable
attorneys’ fees of the prevailing party. 

            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.

                If this Lease is terminated by Landlord pursuant to this 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 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 this 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.

            22.       Landlord’s Default.  If Landlord shall fail to perform any
of the covenants or agreements in this Lease on the part of Landlord to be
performed, and if the default shall continue for thirty (30) days (or such
lesser reasonable period of time if emergency repairs or replacements are
required) following written notice thereof from Tenant to Landlord to cure the
specific default or defaults, in addition to all other remedies provided
hereunder or now or hereafter afforded or provided by law or equity (which
remedies shall be cumulative and non-exclusive), Tenant may at its election
perform such covenant, agreement or work for or on behalf of the Landlord;
provided, however, Tenant shall not have any cure rights if the default is not
capable of being cured within thirty (30) days, but Landlord has commenced the
cure within the thirty (30) day period and is diligently prosecuting the cure to
completion.  Any amount which Tenant shall advance in connection therewith shall
be repaid by Landlord to Tenant, within twenty (20) days after written demand
from Tenant, accompanied with reasonable supporting documentation, together with
interest thereon at  the Default Rate per annum from the date of such advance to
the repayment thereof in full.  If Landlord fails pay Tenant within the twenty
(20) day period, Tenant shall only be permitted to offset the amount due against
Annual Base Rent after obtaining a final, unappealable decision in its favor
from an adjudicatory body.  Notwithstanding anything to the contrary in the
previous sentence, in an emergency, Tenant shall have the right to fulfill
Landlord’s obligation on behalf of Landlord, after reasonable (in the
circumstances) oral notice to Landlord at Landlord’s cost which cost shall be
reimbursed by Landlord as set forth above.

            23.       Services and Utilities.  Throughout the Term, Landlord
shall maintain the Premises in a first-class manner consistent with Comparable
Buildings, shall operate all Base Building Systems consistent with the Final
Base Building Plans, and Landlord shall provide the following listed services
and utilities, namely:

            (a)        heating, ventilation, and air conditioning (“HVAC”) for
the 24 hours a day, seven days a week, as determined by Tenant pursuant to the
computer-controlled system for the Building which, as long as Tenant leases the
entire Building, will be under Tenant’s control ;

            (b)        electric energy in accordance with Section 24 following;

            (c)        automatic passenger elevator service 24 hours a day,
seven days a week, in accordance with the Final Base Building Plans;

            (d)        evening, unescorted janitorial services to the Premises
in accordance with the cleaning specifications attached as Exhibit “J”;

            (e)        hot and cold water sufficient for drinking, kitchen,
lavatory toilet and ordinary cleaning purposes from fixtures either within the
Premises all in accordance with the specifications contained within the Final
Base Building Plans and the Construction Documents;

            (f)         replacement of ceiling tiles and all lighting tubes,
lamp ballasts and bulbs in the Premises;

            (g)        extermination and pest control when and if necessary or
at the request of Tenant; and

            (h)        maintenance of Common Areas in a manner consistent with
other Comparable Buildings.

            (i)         landscaping, road and driveway repair and snow removal
and maintenance of all improvements on the  Property consistent with that found
in Comparable Buildings;

            (j)         A controlled access security system for the Building
permitting access thereto twenty-four (24) hours a day, three hundred sixty-five
(365) days a year, via a Kastle or similar key-card system, including key-cards
for such system; and

            (k)        Operational fire alarm and life safety systems (which, to
the extent applicable, shall include telecommunications systems which are a part
of such systems) in accordance with Applicable Laws and consistent with the
Final Base Building Plans and the Construction Documents

            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.  In the event that Tenant should require supplemental HVAC
for the Premises, any maintenance repair and/or replacement required for such
supplemental service shall be performed by Landlord but the cost of such
maintenance repair and/or replacement (including labor and materials) shall be
paid by Tenant as additional rent.  Notwithstanding the foregoing, in the event
that any of the foregoing services are not provided by Landlord for a period of
six (6) consecutive business days and such cessation is a result of Landlord's
inaction or negligence, then Annual Base Rent and additional rent shall abate
commencing on the seventh (7th) consecutive business day until such services are
restored.

            24.       Electric Current.  Landlord will supply the Premises with
the necessary lines to provide electric service to the Premises for normal
office and data center operations, as well as separate meters so that Tenant’s
consumption of electric power can be separately measured and charged to Tenant
all in accordance with the Final Base Building Plans.  The power distribution to
each floor of the Premises will be at a minimum of 2.5 watts for lighting and
4.5 watts available for convenience power.  Tenant’s use of electrical energy in
the Building shall not at any time exceed the capacity of any of the electrical
conductors and equipment in or otherwise serving the Building, as set forth on
Exhibit “I”. Commencing on the  Commencement Date, Tenant shall pay all charges
for electric and similar utilities or services so supplied directly to the
utility company supplying same when due and before penalties or late charges on
same shall accrue.  Tenant, at Tenant’s expense, shall be responsible for
contacting the utility company to secure an account in Tenant’s name as of the
Commencement Date.  Tenant shall not at any time overburden or exceed the
capacity of the mains, feeders, ducts, conduits, or other facilities by which
electric and similar utilities are supplied to, distributed in or serve the
Premises.  If Tenant desires to install any equipment which shall require
additional electric or similar facilities of a greater capacity than as provided
by Landlord, such installation shall be subject to Landlord’s prior written
approval of Tenant’s plans and specifications therefor, which approval shall not
be unreasonably withheld, conditioned or delayed.  If such installation is
approved by Landlord, all costs for providing such additional electrical and
similar facilities shall be paid by Tenant.

            25.       Telephone and Telecommunications.  Landlord shall arrange
for the installation of telephone service by a provider acceptable to Tenant
(the “Provider”) 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.  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
if Tenant elects to have Landlord complete the Tenant Improvements pursuant to
Section 35, including, without limitation, the closing of the ceiling and the
carpet installation, if applicable.

            In the event Tenant wishes to utilize the services of a telephone or
telecommunications provider other than the current provider, Tenant shall secure
the prior written consent of Landlord before installing its lines or other
equipment, which consent shall not be unreasonably withheld, conditioned or
delayed.  Prior to the commencement of any work in or about the Building by the
alternate provider, the alternate 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 and Landlord, including, without limitation, providing security in
such form and amount as reasonable determined by Landlord.  Each alternate
provider must be duly licensed, insured and reputable.  Landlord shall incur no
expense whatsoever with respect to any aspect of alternate provider’s provision
of its services, including without limitation, the costs of installation,
materials and service.

            In addition, but only in the event that Tenant is no longer leasing
the entire Building, Landlord reserves  for itself and its successors and
assigns the right, subject to Section 11.2 hereof, 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 of
the Building, if any.

            26.       Acceptance of Premises.  Tenant shall have reasonable
opportunity from time to time, provided it does not thereby interfere with the
completion of Landlord’s Items, to examine the Premises prior to the
Commencement Date to determine the condition thereof and progress of
construction of the Base Building Shell and other of Landlord’s Items.  Upon
taking possession of the Premises of delivery of possession of Landlord’s Items,
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
other items described in Section 35.

            27.       Inability to Perform.  Subject to the provisions of this
Lease, this Lease and the obligation of either party to its covenants and
agreements hereunder shall in no way be affected, impaired or excused because of
strikes or labor troubles or any outside cause whatsoever beyond such party’s
control, 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 (“Unavoidable Delay”).  Each party shall promptly notify the other of
any Unavoidable Delay within twenty-five (25) days after the occurrence of the
Unavoidable Delay which prevents such party from fulfilling any of its
obligations under this Lease.

            28.       No Waivers.  The failure of either party to insist, in any
one or more instances, upon a strict performance of any of the covenants of this
Lease, or to exercise any option herein contained, shall not be construed as a
waiver, or a relinquishment for the future, of such covenant or option, but the
same shall continue and remain in full force and effect.  The receipt by
Landlord of rent, with knowledge of the breach of any covenant hereof, shall not
be deemed a waiver of such breach, and no waiver by 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.  Tenant shall
have the right to designate all or any portion of the Building as "secure areas"
to which access shall be restricted.  Should Landlord desire to enter into and
upon any "secure areas", Landlord shall so notify Tenant and Tenant shall make
access to such portions of the Demised Premises available to Landlord within
forty-eight (48) hours thereafter unless Tenant agrees otherwise. 
Notwithstanding anything to the contrary contained herein, Landlord shall be
accompanied by an employee of Tenant in any "secure areas", and Landlord shall
not unreasonably interfere with Tenant’s use of the Premises during any such
entry.  Notwithstanding the foregoing, in the event of an emergency, Landlord
shall be permitted to enter any “secure areas” by any means necessary and Tenant
shall reimburse Landlord for the costs of such entry within thirty (30) days
after receipt of an invoice for such costs.  Except as set forth above with
respect to “secure areas,” Landlord shall have the right, without abatement of
rent, provided Tenant’s use and enjoyment of the Premises is not interfered with
more than a de minimus amount, to enter the Premises with at least forty-eight
(48) hours advance notice, 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 in the case of emergency, no advance notice shall be required to be given
to Tenant.  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,
provided that in no event shall Landlord exercise such rights without Tenant’s
prior consent during the time that Tenant leases seventy-five percent (75%) or
more of the Building unless  Landlord is required to do so by a governmental
authority. In no event shall any of the changes permitted in the immediately
preceding sentence materially and adversely affect Tenant’s business operations
in the Premises.

            Except for the extent arising out of negligent or omission of
Landlord or failure to exercise due care for Tenant’s property.  Tenant hereby
waives and releases any claim against Landlord or its agents or employees for
damages for any injury or inconvenience to or interference with Tenant’s
business, any loss of occupancy or quiet enjoyment of the Premises, and any
other loss occasioned thereby arising out of Landlord’s actions with this
Section.  For each of the aforesaid purposes, Landlord shall at all times have
and retain a key with which to unlock all of the doors in, upon and about the
Premises, excluding Tenant’s vaults, safes, files and “secure areas”, and
Landlord shall have the right to use any and all means which Landlord may deem
proper to open such doors in an emergency in order to obtain entry to the
Premises, without liability to Tenant except for Landlord’s negligent act or
omission and any failure to exercise due care for Tenant’s property.  Any entry
to the Premises obtained by Landlord in accordance with Section shall not

under any circumstances be construed or deemed to be a forcible or unlawful
entry into, or a detainer of, the Premises, or an eviction of Tenant from the
Premises or any portion thereof.

            30.       Estoppel Certificates.  Tenant agrees, at any time and
from time to time, upon not less than fifteen (15) days’ prior written request
by Landlord, but not more frequently than twice in any twelve (12) month period,
to execute, acknowledge and deliver to Landlord an estoppel certificate such 
reasonable form requested by Landlord and acceptable to Tenant 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 to which the rent and other charges have been
paid in advance, if any, and stating whether or not to the 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 to whom the estoppel is addressed.

            31.       Subordination.   Subject to the terms of this Section 31,
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.  (a “Mortgage”).  Tenant shall, at any time hereafter,
within fifteen (15) days after request from Landlord, execute a Subordination,
Non-Disturbance Agreement (“SNDA”) in a reasonable form that may be required by
any mortgage or mort­gagee or overlandlord, provided that no SNDA shall increase
Tenant’s payment obligations or other liability under this Lease or reduce
Landlord’s obligations hereunder (herein a "Mortgagee") substantially in the
form of Exhibit “K” hereto for the purpose of (a) subjecting or subordi­nating
this Lease and the tenancy created hereunder to the lien of any such mortgage or
mortgages or underlying lease, (b) affirming the agreement of the Mortgagee that
so long as no Event of Default hereunder shall have occurred and be continuing,
the leasehold estate granted to Tenant and the rights of Tenant pursuant to this
Lease to quiet and peaceful possession of the Premises shall not be terminated,
modified, affected or disturbed by any action which such Mortgagee may take to
foreclose any such Mortgage, and (c) affirming the agreement of the Mortgagee
and Tenant to attorn to each other as provided in Section 32 hereof. The failure
of Tenant to execute any such instruments, releases or documents shall
constitute a default hereunder.  Notwithstanding the foregoing, as a condition
to Tenant’s agreement hereunder to subordinate Tenant’s interest in this Lease
to any Mortgage, Landlord shall first obtain an SNDA from such Mortgagee for the
benefit of Tenant.

            32.       Attornment.  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 an Event of Default does not exist under this Lease, Tenant's
possession under the provisions of this Lease shall not be dis­turbed by such
Successor..  In the event that the Mortgagee succeeds to the interest of
Landlord hereunder and is advised by its counsel that all or any portion of the
Annual Base Rent or additional rent payable by Tenant hereunder is or may be
deemed to be unrelated business income within the meaning of the United States
Internal Revenue Code or regulations issued thereunder, Mortgagee, as Landlord,
shall have the right at any time, from time to time, to notify Tenant in writing
of the required changes to the Lease. Tenant shall execute all documents
necessary to effect any such amendment within ten (10) days after written
request from Mortgagee, as landlord, provided that in no event shall such
amendment increase Tenant’s payment obligations or other liability under this
Lease or reduce Landlord’s obligations hereunder. 

            33.       Notices.  All notices and other communications to be made
hereunder shall be in writing and shall be delivered to the addresses set forth
below by any of the following means: (a) personal service or receipted courier
service; (b) telecopying (if confirmed in writing sent by the methods specified
in clauses (a), (c) or (d) of this Section), (c) registered or certified first
class mail, return receipt requested, or (d) nationally-recognized overnight
delivery service.  Such addresses may be changed by notice to the other parties
given in the same manner as provided above.  Any notice or other communication
sent pursuant to clauses(a) through (d) hereof shall be deemed received upon
actual receipt or refusal thereof, provided if there is no record of actual

receipt of refusal thereof, any notice or other communication sent pursuant to
clause (c) shall be deemed received five (5) days following deposit in the mail
and/or  if sent pursuant to subsection (d) shall be deemed received the next
succeeding business day following deposit with such nationally recognized
overnight delivery service.   Such deemed receipt shall only apply if delivery
at the applicable notice address was attempted.

            34.       Intentionally Left Blank.

            35.        .  Tenant's Space.Landlord and Tenant acknowledge and
agree that as of the date of this Lease, Tenant has not determined whether it
will construct  the Tenant’s Work (as defined herein) or whether it desires for
Landlord to construct the Tenant’s Work. In order for Tenant to determine
whether Landlord or Tenant will construct Tenant’s Work, the parties have agreed
to the schedule set forth in Section 35.4.2 below so that the parties will have
an agreed set of Construction Drawings (as hereinafter defined), in a condition
suitable for Landlord and/or Tenant to solicit guaranteed maximum price bids for
Tenant’s Work as of December 1, 2003.  Tenant shall notify Landlord in writing
on or before November 1, 2003, whether Tenant will requests Landlord to solicit
a bid from Landlord’s general contractor which is constructing the Base Building
Shell to construct Tenant’s Work (“Bid Request Notice”).   Tenant shall notify
Landlord in writing on or before that date which is fifteen (15) business days
after Landlord provides its bid for Tenant’s Work (the “Election Notice”), if it
elects for Landlord to construct the Tenant’s Work.  If Tenant fails to send
Landlord the Bid Request Notice or the Election Notice as required, Tenant shall
be deemed to have elected to construct the Tenant’s Work itself, and the
provisions of Sections 35.2 and 35.3 shall apply and none of the provisions of
Section 35.4 shall apply. If Tenant sends the Election Notice as required, the
provisions of Sections 35.4 shall govern the construction of Tenant’s Work. 
Sections 35.5 and 35.6 shall apply regardless of whether Landlord or Tenant
constructs Tenant’s Work.

            35.1      Construction of Landlord’s Items. 

                        35.1.1  Landlord, at Landlord’s expense, shall construct
a five (5) story building and parking lot, with a glass and pre-cast exterior,
including building lobby, elevator lobbies on each of floors 2-5, restrooms and
first floor corridors, all as required for a single-tenanted building,
substantially in accordance with the guidelines which are entitled “Suburban
Office Building Design Guidelines” dated January, 2003, which are attached
hereto and made a part hereof as Exhibit “E”  (referred to either as the “Base
Building Shell” or the “Landlord’s Items”), and as more fully described in
greater detail on Exhibit “C” and as depicted on the design drawings attached as
Exhibit “A-2". In addition, Landlord, at Landlord’s expense, shall construct the
Landlord’s Items, as described on Exhibit “C” attached hereto and made a part
hereof.  Landlord and Tenant hereby acknowledge and agree that prior to the
execution of this Lease, Tenant requested Landlord to modify the building which
had initially been planned by Landlord and such modifications have been
incorporated in the Base Building Shell as outlined on Exhibit “L” attached
hereto and made a part hereof (the “Modifications”).  Landlord and Tenant shall
cooperate with each other, negotiate in good faith and work as diligently as
possible after the execution of this Lease to confirm the incremental cost
savings or increases resulting from the each of the items comprising the
Modifications.  Upon mutual agreement of the net cost savings or increases, the
parties shall enter into a written  amendment to this Lease which establishes
the net cost savings or increases.  If there is a net cost savings, the amount
of the Allowance shall be increased by the net cost savings and if there is a
net cost increase, the amount of the Allowance shall be decreased by the by net
cost increase.  If for any reason Landlord and Tenant have not agreed on the net
cost savings or cost increases on or before that date which is ten (10) business
days after receipt of the written estimate from Landlord, Tenant shall be deemed
to have accepted the net cost savings or cost increase as set forth in the
estimate. Tenant acknowledges and agrees that notwithstanding any other
provision of this Section 35 to the contrary, Tenant shall not be permitted to
request any further modifications to the Base Building Shell prior to the date
that Landlord obtains the grading permit and building permit for the Base
Building Shell.   See Section 35.5 regarding potential, future modifications to
the Base Building Shell after the issuance of the grading permit and the
building permit for the Base Building Shell.

Prior to the execution of this Lease, Landlord, at Landlord’s expense, 
delivered architectural floor plans for each of the floors of the Building in
CAD format (“Landlord’s Floor Plans”) in sufficient detail for Tenant to prepare
Space Plans, Design Development Drawings and Final Construction Drawings.  When
available, Landlord shall deliver to Tenant copies of all final plans and
specifications for the Base Building Shell.  Landlord shall be solely
responsible for the development and preparation of the construction documents of
all exterior areas, including, without limitation, appropriate grading, utility,
landscaping and parking lot plans, and for obtaining all necessary local
government and similar approvals for such documents and any necessary easements,
licenses, permits and the like for all site work, which documents shall be
deemed a part of the final plans and specifications for the Base Building Shell.

                        35.1.2  Landlord, at Landlord’s expense, shall complete
the Landlord’s Items all in a good and workmanlike manner.   Landlord covenants
that completion of Landlord's Items shall be constructed in all material
respects in accordance with the construction documents for the Base Building
Shell which shall be substantially in accordance with the Design Drawings
attached hereto as Exhibit “A-2” (“Base Building Construction Documents”) and
shall be in accordance with applicable Federal, State and local rules,
regulations, codes, laws and ordinances (including but not limited to zoning
rules and regulations). Landlord warrants that the roof, HVAC system, windows
and window seals, structural components and all electrical and plumbing systems
and equipment serving the Base Building Shell (the “Base Building Systems”)
shall be in good working order at the time of Delivery of Possession of
Landlord’s Items, except to the extent that the completion of the such systems
is dependent upon the completion of Tenant’s Work.  Any change orders,
construction change directives, or other modifications to the Base Building
Construction Documents shall require Tenant’s prior approval if the Tenant’s
Work is affected thereby, which approval shall not be unreasonably withheld,
conditioned or delayed.

                        35.1.3  If Tenant does not request Landlord to complete
the Tenant’s Work, Landlord shall use its reasonable efforts to achieve Delivery
of Possession of Landlord’s Items (as defined herein) on or before that date
which is twelve (12) months after the issuance of the shell building permit (the
“Target Date”).  Notwithstanding anything herein to the contrary, if the shell
building permit is not issued on or before November 1, 2003, Tenant shall have
the right to terminate this Lease by giving Landlord thirty (30) days’ advance
written notice thereof, provided, however, that if the permit has been issued
prior to the date of Tenant’s termination notice or during the thirty (30) day
period, this Lease shall remain in full force and effect.  The term "Delivery of
Possession of Landlord’s Items" as used hereafter, shall be deemed to have
occurred when (i) Landlord's Items shall have been substantially completed (as
defined below) and Landlord’s contractors have vacated the Premises and removed
all equipment, unused materials and debris, (ii) Landlord shall have made the
Premises available to Tenant and ready for Tenant to obtain the appropriate
governmental approvals to commence the Tenant’s Work (as defined below),
including without limitation, final shell inspections and approvals, (iii) the
parking areas, driveways, loading areas, infrastructure and utilities serving
the Building and the Premises are complete and ready for use, and (iv) Landlord
shall have given Tenant  thirty (30) days’ prior written notice that the items
in (i)-(iii), above, shall be satisfied as of the date of giving such notice. 
Landlord's Work shall be deemed to be “substantially completed” when (i) the
Landlord's Items are completed such that the incomplete portions of Landlord's
Items (i.e., the punchlist items) are such as shall not interfere with Tenant's
ability to perform its work, install its fixtures and equipment and occupy the
Premises; (ii) all means of access and all facilities necessary to Tenant's
occupancy of the Premises, including without limitation, sidewalks, corridors,
exterior doorways, at least two passenger elevators, one service elevator,
stairways, toilets, base building HVAC, water, base building electric lighting
and telephone service to the Building's main telephone room or as otherwise
provided in the Base Building Shell Guidelines, have been properly installed and
substantially completed (free of all scaffolding and construction materials)and
are in good working order and are available to the Premises; (iii) all
facilities and systems serving the Building or any part thereof have been
completed, the exterior of the Building has been substantially completed and is
completely enclosed and the remaining work in the Building is of such a nature
as will not materially interfere with Tenant's construction of the Tenant’s
Work; and (iv) final shell inspections and approvals(or equivalent approval from
the applicable governmental agencies) with respect to the Base Building Shell
have been received and copies delivered to Tenant.

                        35.1.4    If Delivery of Possession of Landlord’s Items
has not occurred on or before the Target Date, subject to extension for Force
Majeure Events as herein defined, Landlord shall pay Tenant liquidated damages
(by means of a credit against Annual Base Rent and additional rent first
becoming due) in an amount which is equal to (i) the daily amount of Base Rent
due hereunder until the Delivery of Possession of Landlord’s Items actually
occurs for the first forty-five (45) days of the delay and (ii) twice the daily
amount of Base Rent due hereunder until the Delivery of Possession of Landlord’s
Items actually occurs commencing on the forty-sixth (46th) day of delay, if
applicable.  Not later than ninety (90) days prior to the Target Date or at any
time prior to such date upon Landlord becoming aware of a probable delay,
Landlord shall notify Tenant in writing of any anticipated delay in the Delivery
of Possession of Landlord’s Items. 

                              35.1.5         The Delivery of Possession of
Landlord’s Items shall be confirmed by a written punchlist prepared by
Landlord’s architect within five (5) business days after the Delivery of
Possession of Landlord’s Items (confirmed by a walkthrough with Tenant’s
architect and Tenant), which shall also set forth the Base Building work
remaining to be performed (the “Base Building Punchlist”) so that the
requirements of the Base Building Construction Document will be fully satisfied,
which Base Building Punchlist shall be subject to approval by Tenant. Within
sixty (60) days after the Delivery of Possession of Landlord’s Items, Landlord
shall complete all items identified in the Base Building Punchlist.  Landlord,
at its expense, shall promptly correct all defects in design, materials and
workmanship in the Base Building Shell for which Tenant sends notice within
twelve (12) months after the Date of Delivery of Landlord’s Items.  If Landlord
fails to meet a material obligation of this Section 35.1.5, and (a) Tenant
provides written notice of such failure, and (b) Landlord fails to fulfill such
obligation within thirty (30) days after receipt of Tenant’s notice of such
failure, then Tenant shall have the right to fulfill such obligation on behalf
of Landlord, the cost of which shall be paid by Landlord promptly following
demand therefore; provided however, that Landlord’s cure period shall be
extended where the failure is not reasonably curable within thirty (30) days
after written notice and Landlord uses good faith efforts and works diligently
and continuously to fulfill its obligations. 

            35.1.6  Tenant and Tenant’s architect shall have the right to
review, at Tenant’s expense, the prosecution of the work contemplated by the
Base Building Construction Documents, and upon reasonable prior notice Landlord
shall allow Tenant and Tenant’s architect access to the Property for such
reviews, provided such access and reviews do not unreasonably interfere with or
delay the completion of the Base Building Shell.  Landlord shall furnish such
information as may be reasonably necessary or pertinent for effectively
reviewing the completion of the Base Building Shell.  The exercise of such
rights of review and access by Tenant or Tenant’s architect shall not relieve
Landlord of any of its obligations pursuant to this Lease and shall not be
construed as acceptance by Tenant or by Tenant’s architect of all or any portion
of the Landlord’s Items.  Tenant shall have the right to attend and observe all
testing and commissioning of Base Building Systems and to receive copies of all
reports generated in connection therewith.  Landlord shall give Tenant
reasonable prior notice of all testing and commissioning.

            35.1.7  Landlord shall regularly consult with and inform Tenant of
the construction schedules for construction of the Base Building Shell and the
progress of the Base Building Shell  (and, if Landlord supervises the
construction of the Tenant’s Work, the Tenant’s Work). 

            35.2        Construction of Tenant’s Work.

           

                        35.2.1   As used herein, the term “Tenant’s Work” shall
refer to all desired improvements to the Premises other than the Landlord’s
Items. Tenant, at Tenant’s expense, shall submit to Landlord, for Landlord's
approval, Tenant's space plan for the Premises and all subsequent related design
drawings and construction drawings in accordance with the provisions of Section
35.4 below.   

                        35.2.2  Intentionally Left Blank.

                        35.2.3  In the event that Tenant does not elect to have
Landlord construct Tenant’s Work, Landlord shall provide Tenant with a
reasonable amount of construction management services in connection with the
construction of both Landlord’s Work and Tenant’s Work for a construction
management fee in the amount of two percent (2%) of the hard and soft costs to
complete the Tenant’s Work (the “Management Fee”), which fee shall not exceed
One Hundred Thousand Dollars ($100,000.00). Such construction management
services shall include, without limitation,  (i) review and approval of Tenant’s
construction drawings and coordination of the completion of Landlord’s Work,
(ii) coordination of Tenant’s access to the Building including the parking areas
and rear entrances,  loading dock, one (1) service elevator and the stairwells
during construction of Tenant’s Work, (iii) overview of the installation of
Tenant’s telecommunication equipment, (iv) confirmation that Tenant’s
security/alarm system and fire alarm system is consistent with the system
installed by Landlord in the Building, (v) coordination with the Base Building
security during construction, (vi) coordination of all noise related work in an
occupied Building (i.e., tie in to fire alarm and sprinkler systems,
hammer-drilling, core drilling during non-business hours), and (vii) location of
dumpster. In the event Tenant elects to have Landlord construct the Tenant’s
Work, Tenant shall have no obligation to pay the Management Fee described in
this Section 35.2.3 and Landlord’s sole compensation in connection with the
Tenant’s Work shall be as set forth in Section 35.4.

                        35.2.4  Unless Tenant elects to have Landlord construct
the Tenant’s Work, in which case it shall be Landlord’s obligation, Tenant shall
apply to the governmental authorities having jurisdiction there over for any
building permit which shall be required in connection with the construction,
installations or alterations designated as Tenant’s Work.  Landlord shall
cooperate with Tenant to facilitate the issuance of the building permit for
Tenant’s Work. Landlord agrees that Tenant may apply for its permit
simultaneously with its delivery to Landlord of the Construction Drawings  for
Landlord’s  approval.

                        35.2.5  From and after Delivery of Possession of
Landlord’s Items, upon prior approval from Tenant, Landlord may re-enter the
Premises to complete any portion of Landlord's Work which has not yet been
completed, provided that the same does not materially interfere with the
scheduling or performance of the Tenant’s Work. During the period of such
re-entry, Landlord shall not unreasonably interfere with the construction of any
of the Tenant’s Work. Landlord shall be liable for and indemnify and hold Tenant
harmless against any injury or damage resulting from or arising out of
Landlord’s construction activities on or within the Building or Property after
Delivery of Possession of Landlord’s Items, excepting acts of gross negligence
or misconduct caused by Tenant’s agents, contractors, representatives and/or
employees. After the Delivery of Possession and issuance of the permit for
Tenant’s Work, Tenant shall, at its sole cost and expense, complete Tenant’s
Work and the installation of Tenant's furniture, fixtures and equipment,
provided that (i) Landlord and Tenant shall have agreed on the Approved Plans
and Specifications, (ii) Tenant shall have delivered to Landlord a copy of the
building permit for Tenant’s Work, and (iii) Tenant shall have deposited with
Landlord the policies or certificates of insurance required under the terms of
this Lease, including without limitation, the contractor’s insurance policy
which names Landlord and Landlord’s mortgagee as additional insureds. Tenant
covenants that completion of  Tenant's Work shall be in accordance with
applicable Federal, State and local rules, regulations, codes, laws and
ordinances (including but not limited to zoning rules and regulations).

                        In addition, in the event Tenant does not elect to have
Landlord construct the Tenant’s Work, prior to commencement of construction of
the Tenant’s Work, Tenant shall deliver to Landlord the names (and other
information as may reasonably be requested by Landlord) of those duly qualified
licensed contractors who will be performing the Tenant’s Work on behalf of
Tenant, which contractors shall be subject to Landlord's prior approval (such
approval not to be unreasonably withheld, conditioned or delayed).  All work to
be performed on or within the Premises by Tenant pursuant to the terms of this
Section 35 shall be performed only by those contractors, subcontractors and
tradespeople licensed to do business in the State of Maryland and approved by
Landlord as aforesaid and shall be performed in accordance with the Interior
Construction and Renovation Requirements, a copy of which is attached hereto as
Exhibit “C-1”.  Tenant shall be liable for and indemnify and hold Landlord
harmless against damage to the Premises, and the Building and Landlord's other
improvements resulting from or arising out of Tenant's construction activities
on or within the Premises, excepting the acts of negligence and misconduct
caused by Landlord's agents, contractors, representatives and/or employees.
Tenant shall cause the improvements to the Premises to be constructed in a good
and workmanlike manner and in accordance with the Approved Plans and
Specifications (as defined in Section 35.4.2(f) hereof). Landlord shall not
require Tenant to employ any particular subcontractors with respect to any
particular trade for Tenant’s Work.

                        Unless Tenant elects to have Landlord construct the
Tenant’s Work, commencing on the Delivery of Possession of Landlord’s Items, (i)
Tenant shall pay any charges for hoisting, Tenant’s use of electrical services
and water and Tenant shall establish an account in its own name directly with
the utility company providing such electrical services and water prior to the
commencement of Tenant’s Work, (ii)  Tenant shall be provided adequate parking
spaces and elevators during construction at no additional cost, and (iii)
Tenant, at Tenant’s expense, shall protect all Base Building areas that have
completed finishes.

                      Notwithstanding anything in this Section 35 to the
contrary, Tenant, at Tenant’s expense, shall engage Corporate Cooling &
Controls,  LLC (“CCC”) to make any changes required to the HVAC control system. 
In addition, Tenant shall coordinate the installation and location of any
supplemental HVAC equipment with Landlord to coordinate roof penetration
concerns and maintain the validity of all existing roof warranties.

                        If Landlord or Landlord’s agents, contractors,
representatives or employees interfere with Tenant’s ability to substantially
complete the Tenant’s Work in any manner, including, but not limited to, by
requiring a cessation of Tenant’s Work or as a result of defects in the
completion of the Landlord’s Items, the Rent Commencement Date shall be delayed
for a period of time which is equal to the length of Landlord’s delay.

            35.3     Disbursement of Allowance.

           

                        35.3.1    If Tenant is responsible for construction of
the Tenant’s Work, the Allowance and the Amortized Amount, if any, shall be
disbursed to Tenant on a progress payment basis.  Proper draw requests submitted
by the 20th day of any calendar month shall be paid by the 15th day of the
following calendar month.  Each of Landlord’s progress payments shall be limited
to an amount equal to the aggregate amounts theretofore paid by Tenant (as
certified by Tenant’s architect) to Tenant’s contractors, subcontractors,
material suppliers, and vendors, and which have not been subject to previous
disbursements from the Allowance.  Tenant shall withhold from its general
contractor, and shall require its general contractor to withhold from each
subcontractor, a retainage equal to ten percent (10%) of each progress payment
made until the Tenant’s Work is fifty percent (50%) complete, and thereafter no
further incremental retainage shall be required if the work is being
satisfactorily prosecuted.  Tenant shall, upon Landlord’s request, provide
adequate evidence of such retainage, and in the event that Tenant fails to
provide such evidence, then Landlord may withhold an amount equal to the
retainage described above.  All requests for disbursement of the Allowance and
the Amortized Amount (as defined herein), if any, shall be accompanied by
certificate signed by Tenant or Tenant’s architect (a) that the sum then
requested was paid by Tenant to contractors, subcontractors, materialmen,
engineers and other persons who have rendered services or furnished materials in
connection with work on the Tenant Work, (b) a complete description of such
services and materials and the amounts paid or to be paid to each of such
persons in respect thereof, and (c) that the work described in the certificate
has been completed substantially in accordance with the Approved Plans and
Specifications and (ii) paid receipts or such other proof of payment as Landlord
shall reasonably require for all such work completed. 

                        35.3.2  If any of the Allowance is not paid pursuant to
subsection (a) above, it shall be paid by Landlord to Tenant upon completion of
the Tenant's Work, to reimburse Tenant for amounts actually paid by Tenant in
connection therewith to Tenant's vendors, suppliers or contractors, provided
that Landlord shall have received (i) a certificate in accordance with the
requirements of subsection (a) above, accompanied by lien waivers satisfactory
to Landlord executed by any contractors or subcontractors for whose labor or
material Tenant has previously been reimbursed pursuant to subsection (a) above,
(ii) paid receipts or such other proof of payment as Landlord shall reasonably
require evidencing that final payment has been made for all materials and labor
furnished in connection with the Tenant Work, and (iii) a copy of a final
unconditional certificate of occupancy evidencing that Tenant may commence
occupancy of the Premises for all purposes set forth in this Lease.

                        35.3.3    Tenant shall be permitted to apply the
Allowance and the Amortized Amount, if any, to any costs associated with the
design and construction of the Tenant’s Work and Tenant’s relocation to the
Premises, including without limitation, the Tenant’s Work, space planning and
design, mechanical, electrical and plumbing engineering costs, construction
fees, tenant improvement cabling, voice/data, phone data costs, built-in and
removable furniture, consultant fees,  any move or relocation costs and
Tenant-initiated and Landlord-approved changes to the Base Building Shell.

                        35.3.4     If the cost to complete the Tenant’s Work
exceeds the Allowance, Landlord shall advance up to the Amortized Amount,
subject to the provisions of Section 35.3.4.1.  Tenant shall notify Landlord
whether it desires Landlord to advance all or any portion of the Amortized
Amount; provided that Tenant shall have no obligation to notify Landlord of its
desire to utilize the Amortized Amount prior to delivery of Possession of
Landlord’s Items..  Such portion of the Amortized Amount which has been advanced
shall be repaid by Tenant to Landlord on a monthly basis, together with Base
Rent, as additional rent, in an amount equal to the amount of the Amortized
Amount which has been advanced, amortized over the ten (10) year term, with
interest accruing at ten percent (10%) per annum.  Tenant shall execute an
amendment to this Lease or an acknowledgment of the Amortized Amount within
fifteen (15) days after receipt of a written statement from Landlord, together
with reasonable supporting documentation.  Notwithstanding that the Amortized
Amount shall be payable as additional rent, it shall be treated and accounted
for separately from other rent payable under this Lease as it will not be
subject to any annual or other rental escalation.  Notwithstanding anything
herein to the contrary, accrual of interest on the Amortized Amount shall not
commence until the date same (or any portion thereof) is disbursed.

                                    35.3.4.1 Notwithstanding anything in Section
35.3.4 to the contrary,  Landlord shall not be required to disburse any portion
of the Amortized Amount if Tenant’s credit rating falls below a “BB-“ as
determined by Standard & Poor’s credit rating agency or Moody’s credit rating
agency.  If, after disbursing all or any portion of the Amortized Amount, 
Tenant’s credit rating falls below a “B+“ as determined by Standard & Poor’s
credit rating agency or Moody’s credit rating agency, Tenant shall repay the
unamortized amount of the Amortized Amount upon fifteen (15) days advance
written notice from Landlord.

                                    35.3.4.2 If Tenant does not elect to utilize
the Amortized Amount within six (6) months after the Rent Commencement Date,
then Tenant shall be deemed to have waived its right to utilize the Amortized
Amount.

                        35.3.5 If Tenant does not fully utilize the Allowance,
Tenant shall be permitted to take a credit against Base Rent in the amount of
the unused Allowance, provided that Tenant utilizes that credit during the first
twenty-four (24) months of the Term.

                        35.3.6 Notwithstanding anything in this Section 35.3 to
the contrary, Landlord shall only be required to disburse the Allowance and the
Amortized Amount on a per square foot basis as Tenant elects to improve the
Premises.  By way of example, but without limitation, if Tenant determines to
improve only 75,000 rentable square feet of the Premises initially, Landlord
shall only be required to disburse $1,650,000 of the Allowance (computed as $22
multiplied by 75,000 rsf) and $750,000 of the Amortized Amount (computed as $10
multiplied by 75,000 rsf), provided that the other conditions for disbursement
have been satisfied.

            35.4  Tenant’s Right to Request Landlord to Construct Tenant's
Work. 

                        35.4.1  If Tenant elects for Landlord to construct
Tenant’s Work, the term “Landlord’s Work” shall then refer to Landlord’s Items
and Tenant’s Work.

                        35.4.2  In order to accommodate Tenant’s desired
occupancy of the Premises and to permit both Landlord and Tenant to solicit bids
for the Tenant’s Work in accordance with the first paragraph of this Section 35,
Landlord and Tenant agree to the following schedule for performance of their
respective responsibilities hereunder:

Deadline for Performance                     Task to be Performed

power/voice/data boxes; special electrical and HVAC requirements; indication of
all modular furniture power connection requirements; general finish schedules.

NOTE:  If Tenant desires to have Landlord prepare a bid for constructing the
Tenant’s Work, then Tenant is required to notify Landlord no later than November

d. 10  business days after receipt of

Design Development Drawings              Landlord to advise Tenant of Design
Development Drawings approval or note why Drawings were not approved and Tenant
to revise accordingly. See note at end of this schedule regarding long lead
items.

e. 51  business days after approval of

Design Development Drawings              Tenant to deliver to Landlord set of
Final Construction  Drawings suitable for permit, bidding and construction.

f. 10  business days after submission

of Construction Drawings                      Landlord to advise Tenant of
Construction Drawings approval or note why Drawings were not approved and Tenant
to revise accordingly.  After approval by the parties and the permitting
authority, the Construction Drawings to be referred to as the “Approved Plans
and Specifications” (provided, however, that if change orders are subsequently
approved by the parties pursuant to the provisions of this Section 35, the term
“Approved Plans and Specifications” shall include the initial approved
Construction Drawings, as modified by the approved change orders.

NOTE:  If Tenant elects to construct the Tenant’s Work itself, the balance of
this Schedule is not applicable and the provisions of Sections 35.1, 35.2, 35.3,
35.5 and 35.6 shall govern the construction of the Tenant’s Work and Tenant
shall apply for the Tenant Improvement permit with Anne Arundel County.

            If Tenant has requested for Landlord to construct the Tenant’s Work,
Landlord shall apply for the Tenant Improvement permit with Anne Arundel County
within two (2) days after receipt of Tenant’s Election Notice and shall
thereafter diligently prosecute the issuance of all necessary permits for the
Tenant’s Work. I

g. November 1, 2004                           Substantial Completion of the
Premises and Delivery of Possession of the Premises by Landlord to Tenant,
subject to extension for Force Majeure Events as described herein (“Landlord’s
Work Target Date”).  Landlord’s Work Target Date shall be extended for delays
arising from Force Majeure Events, but only with respect to Force Majeure Events
occurring after the commencement of construction of the Base Building Shell, as
hereinafter defined.

              If either party is required to resubmit any of its deliveries
hereunder, the submitting and reviewing party, as applicable, shall have five
(5)  business days to resubmit and review, respectively.

            All consents and approvals required from Landlord under this Section
35 shall not be unreasonably withheld, conditioned or delayed; further,
Landlord’s consent or approval shall be deemed granted if Landlord has not
responded (giving reasonable detail for the reasons for denial of consent or
approval) within any specified time period for response stated herein. 
Notwithstanding the foregoing, any objection to a requested consent or approval
shall be for good cause, which shall be limited to the following:  (i) adverse
impact to the structural integrity of the Building or Base Building Systems,
(ii) adverse impact on the Building’s exterior, (iii) lack of compliance with
Applicable Laws, and/or (iv) design materially inconsistent with the designs of
comparable buildings in the National Business Park (e.g., 201, 211 and 221
National Business Park) and Tenant does not agree to restore the Building to a
condition consistent with comparable buildings in National Business Park at the
end of the Term. Landlord's approval of the Space Plan, Design Drawings and the
Construction Documents for Tenant's Work 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.

            Note:  Upon the receipt of the Design Development Drawings described
in Section 35.4.2(c) above, Landlord shall reasonably advise Tenant in writing
whether any of the specifications involve a long lead item and Tenant shall have
five (5) business days after receipt of Landlord’s notice to advise Landlord
whether (i) Tenant shall modify such specification to not require such long lead
item, or (ii) Tenant shall continue to require such long lead item, with the
recognition that arrival and installation of the long lead item may delay
“substantial completion” of Landlord’s Work (as defined in Section 35.4.5).  If
Tenant elects option (ii) above in the immediately preceding sentence regarding
long lead items, and Landlord can substantiate that Landlord was actually
delayed in the completion of Landlord’s Work as a result of delays in delivery
of long lead items, then notwithstanding the incomplete nature of the long lead 
item, “substantial completion” of the Landlord’s Work, as defined in Section
35.4.5,  shall be deemed to occur upon completion of all other items of
Landlord’s Work and the occurrence of all other conditions set forth in Section
35.4.5 which are not affected by the long lead item, even if a certificate of
occupancy or other governmental approvals has not been issued based on the
incomplete nature of the long lead item, provided, Landlord shall in any case
diligently and in good faith pursue substantial completion of Landlord’s Work.

              If either party believes that the other party has failed to meet
any deadline set forth above, it shall notify the other party within twenty-five
(25) business days after the date of the failure in order to collect liquidated
damages or pursue its rights as described in Section 35.4.3 below.

            Notwithstanding anything set forth on the foregoing schedule to the
contrary, if Landlord has in all material respects complied in a timely manner
with its obligations to provide Landlord’s Floor Plans and other obligations
under subsections (b), (d) and (f) and has timely applied for and diligently
prosecuted the issuance of the permit to construct the Tenant’s Work and such
permit is not issued by March 1, 2004, the Landlord’s Work Target Date shall be
extended on a day for day basis for each day of delay beyond March 1, 2004,
until the permit is issued.

                        35.4.3  Landlord, at Landlord’s expense, shall complete
the Landlord’s Work, all in accordance with the Approved Plans and
Specifications in a good and workmanlike manner.   Landlord covenants that
completion of Landlord's Work shall be in accordance with applicable Federal,
State and local rules, regulations, codes, laws and ordinances (including but
not limited to zoning rules and regulations).   If Tenant requests Landlord to
construct the Tenant’s Work, Landlord shall hold bi‑weekly meetings to discuss
the progress of the Landlord’s Items.  Landlord shall schedule such meetings at
more frequent intervals when needed, or upon the reasonable request of Tenant.

                        35.4.4  Any alterations, modifications or deviations to
the final Approved Plans and Specifications requested by Tenant shall be made in
the form of a written change order(s) prepared at Tenant's sole cost and
expense, which costs shall include, but not be limited to, the engineering fees
incurred by Landlord  (but as part of Tenant’s Work Costs) and if made after the
“Change Order Date” (as hereinafter defined), shall be subject to the prior
approval of Landlord, which approval shall not be unreasonably withheld,
conditioned or delayed.  The costs of work performed by Landlord pursuant to
Tenant's approved written change orders shall include all net increases in costs
of labor and materials plus if such change order is requested after the Change
Order Date, an amount equal to five percent (5%) of the net increase in hard
costs for overhead and profit.  As used herein, the term “Change Order Date”
means the date on which Landlord  commences construction of the Tenant’s Work. 
At Tenant's request, Landlord shall fully cooperate with Tenant to establish
such costs or estimates thereof in advance of performing the work.

                        35.4.5  If Landlord fails to Deliver Possession of the
Premises with the Landlord’s Work substantially completed (as defined herein) on
or before the Landlord’s Work Target Date, subject to extension for Force
Majeure Events, Landlord and Tenant agree that the damages to Tenant would be
difficult to ascertain and, therefore, as Tenant’s sole remedy hereunder,
Landlord agrees to pay Tenant a liquidated damages sum (by means of a credit
against Annual Base Rent and additional rent first becoming due) equal to (i)
the daily Base Rent due hereunder until the Delivery of Possession of Landlord’s
Work actually occurs for the first forty-five (45) days of the delay, and (ii)
twice the daily amount of Base Rent due hereunder until the Delivery of
Possession of Landlord’s Work actually occurs commencing on the forty-sixth
(46th) day of delay, if applicable. Not later than ninety (90) days prior to the
Landlord’s Work Target Date or at any time prior to such date upon Landlord
becoming aware of a probable delay, Landlord shall notify Tenant in writing of
any anticipated delay in the Delivery of Possession of Landlord’s Work.  The
term "Delivery of Possession” as used herein, shall be deemed to have occurred
when (i) Landlord's Work shall have been substantially completed (as defined
below) and Landlord’s contractors have vacated the Premises, and (ii) Landlord
shall have notified Tenant that the Premises are substantially completed.
Landlord shall use its reasonable efforts to give Tenant at least fifteen (15)
days’ advance notice that the Landlord’s Work will be substantially completed.
Landlord's Work shall be deemed to be “substantially completed” when (i) the
Landlord's Work are completed such that the incomplete portions of Landlord's
Work (i.e., the punchlist items) are such as shall not interfere with Tenant's
ability to install its furniture, fixtures and equipment; (ii) all facilities
and systems serving the Building and Premises have been completed, the exterior
of the Building has been substantially completed and is completely enclosed and
the remaining work in the Building (outside the Premises) is of such a nature as
will not materially interfere with Tenant’s occupancy of the Premises, and (iii)
Landlord has obtained and delivered to Tenant an unconditional certificate of
use and occupancy or equivalent approval from the applicable governmental
agencies with respect to the Premises and Tenant’s Work, the interior and
exterior Common Areas and Base Building Shell.  Landlord shall keep Tenant
advised of the status of substantial completion of Landlord’s Work. 
Notwithstanding the foregoing, the requirements of subsection (iii) 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
Work.  The Delivery of Possession of Landlord’s Work shall be confirmed by a
written punchlist prepared by Landlord’s architect within five (5) business days
after the Delivery of Possession of Landlord’s Work (confirmed by a walkthrough
with Tenant’s architect and Tenant), which shall also set forth the Landlord’s
Work remaining to be performed (the “Landlord’s Work Punchlist”) so that the
requirements of the Approved Plans and Specifications will be fully satisfied,
which Landlord’s Work Punchlist shall be subject to approval by Tenant. Within
sixty (60) days after the Delivery of Possession of Landlord’s Work, Landlord
shall complete all items identified in the Landlord’s Work Punchlist.  Landlord,
at its expense, shall promptly correct all defects in design, materials and
workmanship in the Landlord’s Work for which Tenant sends notice within twelve
(12) months after the Date of Delivery of Landlord’s Work.  If Landlord fails to
meet a material obligation of this paragraph, and (a) Tenant provides written
notice of such failure, and (b) Landlord fails to fulfill such obligation within
thirty (30) days after receipt of Tenant’s notice of such failure, then Tenant
shall have the right to fulfill such obligation on behalf of Landlord, the cost
of which shall be paid by Landlord promptly following demand therefore; provided
however, that Landlord’s cure period shall be extended where the failure is not
reasonably curable within thirty (30) days after written notice and Landlord
uses good faith efforts and works diligently and continuously to fulfill its
obligations. 

            For the purposes of this paragraph, the term “Tenant Net Delay”
shall refer to the number of days, if any, that Tenant has (i) delayed in
fulfilling its obligations under subsections (a), (c), and (e) of Section 35.4.2
(i.e., taking into account both time delays and time savings from required
dates); the term “Landlord Delay” shall refer to the number of days, if any,
that Landlord has delayed in fulfilling its obligation under subsections (b),
(d), (f) of Section 35.4.2; the term “Total Delay” shall refer to the Tenant Net
Delay reduced by the Landlord Delay.  Notwithstanding anything herein to the
contrary, if the Total Delay is in excess of five (5) days but less than sixty
(60) days, the date of Delivery of Possession of Landlord’s Work (and
correspondingly, the Commencement Date)  shall be deemed to be the date of the
actual date of Delivery of Possession of Landlord’s Work backdated by the Total
Delay.  If, however, Landlord and Tenant agree on the Approved Plans and
Specifications as required by Section 35.4.2(f) on or before  December 1, 2003,
regardless of the amount of Total Delay, or in the event Landlord is unable to
substantiate that Landlord was actually and materially delayed in completing
Landlord’s Work as a result of the Tenant Net Delay as aforesaid, then in either
such case this paragraph shall be of no further force or effect. Notwithstanding
the immediately preceding sentence, if the Total Delay exceeds sixty (60) days,
regardless of the status of agreement on the Approved Plans and Specifications,
the Delivery of Possession of Landlord’s Work shall be deemed to be the earlier
of (i) November 1, 2004, or (ii) the actual date of Delivery of Possession of
Landlord’s Work.  By way of example, but without limitation, assume Tenant Net
Delay is 12 days and Landlord Delay is 2 days, (i) if Landlord and Tenant agree
on the Approved Plans and Specifications on November 30, 2003, the Delivery of
Possession of Landlord’s Work shall be the actual date; however, if Landlord and
Tenant agree on the Approved Plans and Specifications after November 30, 2003
and the actual date of Delivery of Possession of Landlord’s Work occurs on
November 11, 2004, the Commencement Date will be deemed to be November 1, 2004
after taking into account the Total Delay of ten (10) days.

            35.4.6  Cost of Tenant’s Work.

                        35.4.6.1           The term “Tenant’s Work Costs” shall
refer to the actual costs of constructing the Tenant’s Work (including
reimbursable items, such as permit fees, prints, telephone, mileage and
postage); and a construction management fee of five percent (5%) based solely on
hard costs for work performed by Landlord or its contractors, including without
limitation, permitting costs; and other costs as herein described in this
Section, which fee Landlord shall deduct from the Allowance and the Amortized
Amount pro rata as amounts are disbursed therefrom to pay hard costs of
construction and, after the Allowance and the Amortized Amount are exhausted,
the balance of such fee shall be paid by Tenant.

                        35.4.6.2           If the amount of Tenant’s Work Costs
exceed the Allowance, Landlord, at Tenant’s option, upon written request from
Tenant, shall advance an additional amount not to exceed the Amortized Amount. 
Such portion of the Amortized Amount which has been advanced shall be repaid by
Tenant to Landlord on a monthly basis, in equal installments, together with Base
Rent, as additional rent, but without any escalations, in an amount equal to the
amount of the Amortized Amount which has been advanced, amortized over a ten
(10) year term, with interest accruing at ten percent (10%) per annum.  Tenant
shall execute an amendment to this Lease or an acknowledgment of the Amortized
Amount within fifteen (15) days after receipt of a written statement from
Landlord, together with reasonable supporting documentation.  Any Tenant’s Work
Costs incurred by Landlord in excess of the difference between Thirty-Two
Dollars ($32.00) per rentable square foot (which is the sum of the Allowance and
the Amortized Amount) and the disbursements made to Tenant in accordance with
Section 35.4.6.2, shall be paid by Tenant to Landlord within thirty (30) days
after receipt of a written invoice, together with reasonable supporting
documentation.

            35.5     Modifications to Base Building Shell.  Regardless of
whether Tenant constructs Tenant’s Work or elects for Landlord to construct
Tenant’s Work, if Tenant requests Landlord to make a change to the Base Building
Shell after the issuance of the grading permit and the building permit for the
Base Building Shell, Landlord shall promptly notify Tenant in writing whether it
approves such change and if so, in reasonable detail of the additional or
incremental cost to make such change and the change to the Target Date or to
Landlord’s Work Target Date, as applicable (“Landlord’s Response Notice”).  In
no event shall Landlord be required to approve a change(s) which would result in
an aggregate delay (when combined with other requested modifications to the Base
Building) of more than sixty (60) days in the Target Date  or the Landlord’s
Work Target Date.  Tenant shall have five (5)  business days after receipt of
Landlord’s notice to advise Landlord whether (i) Tenant shall modify such
specification to not require such Base Building Shell, or (ii) Tenant shall
continue to require such Base Building Shell modification, with the recognition
that the modification to the Base Building Shell may delay Delivery of
Possession (“Tenant’s Modification Notice”).   If Tenant accepts the terms set
forth in the Landlord’s Response Notice in a timely fashion, Landlord and Tenant
shall mutually execute an acknowledgment or amendment to this Lease which sets
forth the revised Target Date or Landlord’s Work Target Date, as applicable, and
the credit to be given to Tenant or additional costs to be paid by Tenant, as
the case may be, in accordance with the provisions  of this Section 35.5.

If the change requested by Tenant causes an increase in costs, whether or not it
will also cause a delay in the Target Date or the Landlord’s Work Target Date,
Landlord shall not be obligated to approve the change unless Tenant agrees, in
writing, to pay or reimburse Landlord for the increased cost of the Base
Building Work caused by the change, based on a firm price from Landlord.  The
increased cost caused by any change shall be reasonably detailed and supported
by reasonably complete and sufficient backup documentation.  To the extent that
a change requested by Tenant results in a decrease in the cost to complete the
Base Building Shell, the amount of such decrease shall be paid by Landlord to
Tenant in the form of a dollar‑for‑dollar increase in the Allowance.  To the
extent that a change results in an increase cost to complete the Base Building
Shell, at Tenant’s sole election, either Tenant shall pay cash therefore or, the
Allowance shall be decreased on a dollar‑for‑dollar basis.  Tenant shall advise
Landlord of its payment election simultaneously with Tenant’s Modification
Notice and if Tenant elects to pay cash therefore, Tenant shall pay such amount
within thirty (30) days after the date of Tenant’s Modification Notice.

If the change requested by Tenant will cause a delay in the Target Date or the
Landlord’s Work Target Date, as applicable, Landlord shall not be obligated to
approve the change unless Tenant agrees, in writing, that such delay shall not
postpone or defer the Rent Commencement Date and that the Rent Commencement Date
shall occur on the day when it would otherwise have occurred if such change had
not been made as determined in accordance with the immediately succeeding
sentence. To determine the Rent Commencement Date that would have occurred, the
parties acknowledge that (i) Landlord will be required to complete the
Landlord’s Item or the Landlord’s Work, as applicable, (ii) determine the actual
date of Delivery of Possession of Landlord’s Items or the Delivery of Possession
of Landlord’s Work, as applicable (in either case, referred to as the “Actual
Delivery Date”) and then (iii) backdate the Rent Commencement Date from the
Actual Delivery Date by the number of days set forth in Landlord’s Response
Notice as the additional time required to complete the modification.  By way of
example, but without limitation, Tenant has requested a modification to the Base
Building Shell which Landlord advises Tenant will delay the Delivery of
Possession of Landlord’s Items by 21 days and the Actual Delivery Date is June
22, 2004, then the Rent Commencement Date shall be deemed to be June 1, 2004.

If the change requested by Tenant will cause a delay in the Target Date or the
Landlord’s Work Target Date, as applicable, Landlord shall not be obligated to
approve a change unless Tenant agrees, in writing, that the Target Date and the
Landlord’s Work Target Date, as applicable, shall be equitably adjusted to
accommodate the additional time required to make the change. 

            35.6     Definition of “Force Majeure Events”.  As used in this
Section 35, the term “Force Majeure Events” shall refer to events which delay or
prevent  either party from constructing, making any repairs, rebuilding or
restoring, or furnishing any construction services or performing any other
construction covenant or duty (as compared to obtaining issuance of the permit
for Base Building Shell, Landlord’s Items or Tenant’s Work), whether express
herein or implied, to be performed by such party due to strike, lockout,
weather, embargo, war, governmental orders or acts of God.  If either party
claims a Force Majeure Event has occurred, it shall notify the other party in
writing within twenty-five (25) days after the occurrence of such event.

            36.       Quiet Enjoyment.  Tenant, upon the payment of rent and the
performance of all the terms of this Lease, shall at all times during the Term
peaceably and quietly enjoy the Premises without any disturbance from Landlord
or any other person claiming through Landlord.

            37.       Vacation of Premises.  Tenant shall vacate the Premises at
the end of the Term.  Subject to the provisions of this Section 35, if Tenant
fails to vacate within five (5) days after the end of the term there shall be
payable to Landlord an amount equal to one hundred fifty percent (150%) of the
monthly Annual Base Rent stated in Section 1.1.6 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
reasonable attorneys’ fees and expenses incurred in connection therewith. 
Notwithstanding the foregoing, if (i) Tenant delivers notice to Landlord at
least  twelve (12) months prior to the expiration of the Term setting forth its
intent to hold over for a fixed period of time not to exceed twelve (12) months,
and (ii) Landlord has not already executed and delivered a lease for all or a
part of the Premises to a new tenant (a “New Tenant”), and (iii) an Event of
Default is not continuing as of the date of its notice or at the expiration of
the Term, then Tenant may remain in the Premises for the period set forth in its
notice so long as Tenant pays as a monthly Rent equal to one hundred  ten
percent (110%) of the Annual Base Rent payable under this Lease for the last
full calendar month of the Term plus all other payments provided for herein.  If
Tenant holds over beyond the period set forth in its notice the first
two sentences of this Section 37 shall apply.  Upon request by Tenant, Landlord
shall inform Tenant whether or not Landlord has executed leases for all or part
of the Premises and the terms of such leases to the extent the same affect
Tenant’s ability to holdover after the end of the term.

            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 limited to the net assets of the Owner from time to time,
including insurance proceeds and other proceeds from the Property.  No member of
Owner, or of any suc­cessor partnership, whether now or hereafter a member,
shall have any personal responsibility or liability for the obligations of Owner
hereunder.  Landlord agrees during the Term of this Lease that it shall not
accept financing secured solely by the Premises with a loan-to-value ratio of
greater than ninety percent (90%) as of the date of the loan; provided, however,
that Landlord may accept financing with a loan-to-value ratio of greater than
ninety percent (90%) if simultaneously with the disbursement of the loan
proceeds Landlord provides to Tenant an irrevocable letter of credit from an
issuer and in form and substance reasonably acceptable to Tenant in the amount
of two million dollars ($2,000,000) to secure Landlord’s obligations under this
Lease.

            39.       Separability.  If any term or provision of this Lease or
the application thereof to any person or circumstances shall, to any extent, be
invalid or unenforceable, the remainder of this Lease or the application of such
term or provision of such term or provision to persons or circumstances other
than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each term and provision of this Lease shall be valid and
be enforced to the fullest extent permitted by law.

            40.       Indemnification. 

            40.1     Tenant’s Indemnification.  Except to the extent arising out
of the negligent act or omission of Landlord, Tenant shall indemnify and hold
harmless Landlord and all of its and their respective members, partners,
directors, officers, agents and employees from any and all liability, loss, cost
or expense arising from all third-party claims resulting from or in connection
with any act, omission or negligence of Tenant or any of its subtenants or
licensees or its or their partners, directors, officers, agents, employees,
invitees or contractors; and together with all costs and expenses reasonably
incurred or paid in connection with each such claim or action or proceeding
brought thereon, including, without limitation, all reasonable attorney’s fees
and expenses.

            In case any action or proceeding is brought against Landlord and/or
any of its and their respective partners, directors, officers, agents or
employees and such claim is a claim from which Tenant is obligated to indemnify
Landlord pursuant to this Section, Tenant, upon written notice from Landlord
shall resist and defend such action or proceeding (by counsel reasonably
satisfactory to Landlord).  The obligations of Tenant under this Section shall
survive termination of this Lease for one (1) year.

            40.2     Landlord’s Indemnification.  Except to the extent arising
out of the negligent act of omission of Tenant, Landlord shall indemnify and
hold harmless Tenant and all of its and their respective members, partners,
directors, officers, agents and employees from any and all liability, loss, cost

Tenant shall resist and defend such action or proceeding (by counsel reasonably
satisfactory to Tenant).  The obligations of Landlord under this Section shall

            45.       Integration of Agreements.  This writing is intended by
the Parties as a final expression of their agreement and is a complete 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 any of the terms of this Lease.  Acceptance of,

shall install, maintain and remove the equipment using a roofing and other
contractors reasonably approved by Tenant.  Tenant shall indemnify and hold
Landlord, its successors, assigns, agents, licensees and invitees harmless from
any and all damages, costs, claims, expenses, actions (including reasonable
attorney’s fees in connection with the equipment, unless resulting form
Landlord’s negligence.

signage and the cost thereof shall be included as a Building Expense. Tenant, at
Tenant’s sole expense, shall pay for all costs associated with the permitting,
purchase, installation and removal of the signage at the expiration or sooner

R E C I T A L S:

_____________________, 200_,  as amended, from time to time, Beneficiary and
certain other financial institutions that are or may become parties to such
agreements (collectively “Lenders”) have made or agreed to make a loan and to
extend certain other financial accommodations (collectively the “Loan”) to an
entity of which Landlord is a subsidiary, CORPORATE OFFICE PROPERTIES, L.P., a
Delaware limited partnership, and to certain of its subsidiaries.  The Loan is
evidenced by promissory notes (collectively, as amended, the “Notes”), which
Notes are or will be secured by a mortgage or deed of trust in favor of
Beneficiary covering the Property (the “Mortgage”).

            C.        In order to induce Beneficiary to make the Loan and to
maintain the financial accommodations extended thereunder, the parties hereto
have agreed to subordinate the Lease to the lien of the Mortgage on the terms
set forth in this Agreement.  In order to induce Tenant to execute and deliver
this Agreement, Beneficiary has agreed not to disturb Tenant’s possession of the
Premises under certain circumstances set forth herein.

            NOW, THEREFORE, in consideration of the mutual covenants contained
herein and of other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties agree as follows:

            1.         Subordination.  Notwithstanding anything to the contrary
set forth in the Lease, the Lease and the leasehold estate created thereby and
all of Tenant’s rights thereunder shall be and shall at all times remain
subject, subordinate and inferior to the Mortgage and the lien thereof, and all
rights of Beneficiary thereunder and to any and all renewals, modifications,
consolidations, replacements and extensions thereof.

            2.         Acknowledgments and Agreements by Tenant.  Tenant and
Beneficiary acknowledge and agree that:

                        2.1.      Landlord has executed and delivered to
Beneficiary a Mortgage, including an assignment of the Lease and the rents
thereunder, and certain other agreements evidencing and securing the Loan. 
Tenant hereby recognizes and agrees to honor such assignment of the Lease and
rents thereunder.  If Beneficiary notifies Tenant in writing of a default under
the Mortgage and demands that Tenant pay its rent and all other sums due under
the Lease to the Beneficiary, Tenant shall honor such written demand and pay its
rent and all other sums due under the Lease directly to Beneficiary or as
otherwise required pursuant to such notice.  Beneficiary hereby releases Tenant
and shall indemnify, defend and hold harmless Tenant from and against any
losses, liabilities, claims or causes of action Tenant may suffer as a result of
compliance with Beneficiary’s notice.

                        2.2.      Tenant shall send a copy of any notice or
statement required to be delivered under the Lease to Beneficiary at the same
time such notice or statement is sent to Landlord, in the manner specified in
this Agreement.

                        2.3.      In the event of any act or omission by
Landlord which would give Tenant the right, either immediately or after the
lapse of time, to terminate the Lease or to claim a partial or total eviction,
Tenant will not exercise any such right until:

                                    2.3.1    it has given written notice of such
act or omission to Beneficiary; and

                                    2.3.2.   the same period of time as is given
to Landlord under the Lease to cure such act or omission shall have elapsed
following such giving of notice to Beneficiary.

If Beneficiary cannot cure Landlord’s breach or default by Landlord under the
Lease and provided that such breach does not result in Tenant being unable to
conduct its normal business operations in the Premises, the period for
Beneficiary to cure Landlord’s act or omission shall be extended for so long as
Beneficiary is diligently pursuing such cure, but not longer than one hundred
twenty days.

                        2.4.      Tenant has no right or option to purchase the
Premises or the Property, or any portion thereof or any interest therein.  To
the extent that Tenant hereafter acquires any such right or option to purchase
the Premises or the Property, the same is hereby acknowledged to be subject and
subordinate to the Mortgage and is hereby waived and released as against
Beneficiary except to the extent Beneficiary agrees in writing to the contrary.

                        2.5.      Beneficiary, in making any disbursements to
Landlord, is under no obligation or duty to oversee or direct the application of
the proceeds of such disbursements, and such proceeds may be used by Landlord
for purposes other than improvement of the Property.

                        2.6.      This Agreement satisfies any condition or
requirement in the Lease relating to the grant of a non-disturbance agreement by
Beneficiary.

Mortgage, or upon a transfer of the Property by conveyance in lieu of
foreclosure, then:

terms, covenants or conditions of the Lease or this Agreement (beyond the
expiration of any applicable notice and cure periods), Tenant’s occupancy of the
Premises shall continue, undisturbed on the terms and conditions contained in
the Lease for the balance of the term of the Lease.  Tenant shall attorn to and
accept any successor owner of the Building as landlord under the Lease, and be
bound by and perform all of the obligations imposed by the Lease, and any
successor owner of the Property will not disturb the possession of Tenant, and
will be bound by all of the obligations imposed on the Landlord by the Lease. 
Any purchaser at a foreclosure sale, by deed in lieu thereof, or any other
successor owner of the Property shall not be:

                                    3.1.1.   liable for any act or omission of a
prior landlord (including Landlord), except for defaults of a continuing nature
which continue after the date Beneficiary acquires title to the Property by
foreclosure or conveyance in lieu of foreclosure; or

                                    3.1.2.   subject to any offsets or defenses
which Tenant might have against any prior landlord (including Landlord), except
those that relate to defaults of a continuing nature which continue after the
date Beneficiary acquires title to the Property by foreclosure or conveyance in
lieu of foreclosure; or

                                    3.1.3.   bound by any rent or additional
rent which Tenant might have paid in advance to any prior landlord (including
Landlord) for a period in excess of one month or any security deposit or other
prepaid charge which Tenant might have paid in advance to any prior landlord
(including Landlord) other than the security deposit, and then only to the
extent actually turned over to such successor owner; or

                                    3.1.4.   bound by any material agreement or
material modification of the Lease made without the written consent of
Beneficiary which consent shall not be unreasonably withheld, conditioned or
delayed.

                        3.2.      Upon the written request of either Beneficiary
or Tenant to the other given following any foreclosure or conveyance in lieu
thereof, the parties agree to execute a lease of the Premises upon the same
terms and conditions as the Lease between Landlord and Tenant which lease shall
cover any unexpired term of the Lease existing prior to such foreclosure or
conveyance in lieu of foreclosure.

           

            4.         Acknowledgments and Agreements by Landlord.  Landlord, as
landlord under the Lease and mortgagor under the Mortgage, acknowledges and
agrees for itself and its heirs, successors and assigns that:

                        4.1.      This Agreement does not waive any of
Beneficiary’s rights under the Mortgage, or in any modify or release Landlord
from its obligations to comply with the Mortgage;

                        4.2.      The Mortgage remains unmodified and in full
force and effect; and

                        4.3.      Landlord hereby irrevocably directs Tenant to
recognize and honor Landlord’s assignment to Beneficiary of the Lease and the
rents thereunder.  If Beneficiary notifies Tenant in writing of a default under
the Mortgage and demands that Tenant pay its rent and all other sums due under

directly to Beneficiary or as otherwise required pursuant to such notice. 
Landlord hereby releases Tenant and shall indemnify, defend and hold harmless
Tenant from and against any losses, liabilities, claims or causes of action
Tenant may suffer as a result of compliance with Beneficiary’s notice.  Tenant

Lease.  Landlord shall look solely to Beneficiary with respect to any claims
Landlord may have on account of an incorrect or wrongful notice. Tenant shall be
entitled to full credit under the Lease for any rent paid to Beneficiary
pursuant to a notice to the same extent as if such rent were paid directly to
Landlord.

            5.         Obligations of Beneficiary.  Beneficiary shall have no
obligation or incur any liability with respect to the erection or completion of
the improvements in which the Premises are located or for completion of the

payment and discharge of any obligations imposed upon the Purchaser hereunder or

MODIFICATIONS TO BASE BUILDING

NBP 220 Design Modifications to Shell Base Building

The following is a list of design and construction modifications to the NBP 220
shell building requested by Titan Corporation (Titan). The items identify above
standard revisions to the original base building design and construction and
were developed during several design review meetings with Titan and their
architect, Burt Hill. In addition, we also identified various credits to Titan
for items normally installed as a part of the base building that Titan has
elected to complete as a part of their tenant work. The costs associated with
these modifications will be developed and submitted to Titan for their review
within the next few weeks.

Scope additions to base building:

1. Recess slab on grade 4'- 4" to accommodate 200+ person auditorium on the
first floor.

Costs to include design and engineering (architectural, structural, MEP) and
construction, lowered footings, longer and/or heavier steel columns, retaining
walls and foundations, piers, excavation and haul off of material, drain tile,
and waterproofing. In addition, provisions will be made to provide space and
support for a supplemental HVAC unit on the roof.

2. Service Area/ Loading Dock relocation from northwest to northeast side of the
building.

Costs to include architectural redesign of first floor core plan that includes
the relocation of the restrooms, elevators, corridors, and service rooms as well
as civil redesign of the loading dock and parking areas.

3. Addition of a rear building entrance.

Costs to include the design, engineering, and construction of a rear building
entrance with double doors and a vestibule. Additional sidewalks will be added
to access the building.

4. Parking increase from 600 to 700+ spaces.

Costs to include civil redesign of site plan to add 100+ additional parking
spaces above base building standard of 4 spaces per 1000sf of space. This
revision also changed the site access off Carina Road and increased the required
area for storm water retention areas directly proportional to the hard surface
area increase. Construction costs will include the 100+ additional spaces,
associated curb and gutter, additional site concrete (sidewalks), storm water
utilities and the increase in storm water management requirements.

5. Design and installation of new restroom/shower room facility

Costs to include the design and construction of a new restroom/shower room that
incorporates Titan's desire for a shower facility that also provides the
additional fixtures required by the auditorium use. Two restrooms, with 3
fixtures and 2 lavatories each, as well as 2 shower rooms with 3 showers and 18
half sized lockers each will be installed and finished. Construction costs will
include the walls, ceilings, finishes, fixtures, plumbing and mechanical
systems. HVAC will be a part of the core roof top unit.

6. Site modifications.

Costs to include the design and construction of a patio area, with furniture, to
be located at the rear entrance to the facility.

7. Secured ductbank.  [Lined out and initialed]

8. Back-up generator

Costs to include the installation of below grade conduits from the main electric
room to a predetermined location 5' outside the building to allow for future
installation of a generator.

9. Upgrade of building main electrical service.

Costs to include the design and installation of upgraded main electric service
to the facility. Current base building design calls for a 3000A service. Titan
stated they might require an increase in this service to accommodate their
tenant requirements. Titan is to provide a request for this service (if desired)
during the next month.

10. Exterior wall SCIF modifications.

COPT is currently working with Titan to modify the exterior wall detail normally
provided with a shell base building to incorporate several design and
construction provisions that provide for SCIF level security. Costs to include
the design and construction of this above standard installation.

NBP 220 Design Modifications to Shell Base Building

Credits to base building construction:

Titan has notified COPT that they would like to install finishes in various
areas of the base building to integrate with their tenant design. In addition,
Titan requested that some areas of the building not be finished in order to
avoid rework due to damage from tenant construction or demolition. The following
is a list of the base building areas and the level of finishes to be provided.

1. COPT will provide finishes in the following areas as part of the shell
building construction: mechanical room, main telephone room, main electrical
room, all restrooms, janitor closets, all telephone/electric rooms (2 per
floor), three elevators, elevator machine room, and front and rear vestibules.
Since these rooms will have all finishes provided, there is_ no credit to Titan.

2. Titan has requested that the following areas not be finished to avoid damage
during tenant build-out: egress corridors, loading dock corridor, the three
stairwells, and the restroom vestibules on each floor. These areas will have
drywall, ceiling grid, ceiling tile, sprinklers, and lights, etc. installed as a
part of the base building. The drywall will be spackled and ready for paint
(since the stairwell walls are masonry they will be pointed up and prime coated)
and the tile will be installed under the water fountains. Titan will receive a
credit for paint and flooring not completed.

3. Titan has requested that the following areas not be built out as part of the
base building: main entrance lobby on the first floor, elevator lobbies on all
floors, and first floor tenant corridors. Titan will be given a credit for all
work deleted from these areas. Items include framing and drywall, painting,
flooring, lights, ceilings, wall finishes, etc. The credit will be based on the
level of finishes currently in NBP 201.

4. Titan has requested that all the building interior columns on all floors not
be framed and drywalled (with the exception of the wet stacks). Titan will
receive a credit for not installing, taping and spackling the drywall.
