         5.2      Estimated Payments. During each calender year or partial
calendar year in the term, in addition to monthly rent, tenant will pay to
landlord on the first day of each month an amount equal to 1/12 of the product
of tenant's share multiplied by the "estimated operating expenses" (defined
below) for such calendar year. "Estimated operating expenses" for any calendar
year means landlord's reasonable estimate of operating expenses for such
calendar year, less the operating expenses base. During any partial calendar
year during the term, estimated operating expenses will be estimated on a
full-year basis. During each December during the term, or as soon after each
December as practicable, landlord will give tenant written notice of estimated
operating expenses for the ensuing calendar year. On or before the first day of
each month during the ensuing calendar year (or each month of the term, if a
partial calendar year), tenant will pay to landlord 1/12 of the product of the
tenant's share multiplied by the estimated operating expenses for such calendar
year, however, if such written notice is not given in December, tenant will
continue to make monthly payments on the basis of the prior year's estimated
operating expenses until the month after such written notice is given, at which
time tenant will commence making monthly payments based upon the revised
estimated operating expenses, together with any arrange really to the earlier
months. If at any time or times it reasonably appears to landlord that the
actual operating expenses for any calendar year will vary from the estimated
operating expenses for such calendar year, landlord may, by written notice to
tenant, revise the estimated operating expenses for such calendar year, and
subsequent payments by tenant in such calendar year will be based upon such
revised estimated operating expenses.

         5.3      Annual Settlement. After the end of each calendar year,
landlord will deliver to tenant a statement of amounts payable under Section 5.1
for such calendar year. If such statement shows an amount owing by tenant that
is less than the estimated payments previously made by tenant for such calendar
year, the excess will be credited against the next payments of rent: however, if
the term has ended and tenant was not in default, landlord will refund the
excess to tenant. If such statement shows an amount owing by tenant that is more
than the estimated payments previously made by tenant for such calendar year, if
said amount is equal to or less than one (1) months rent, tenant will pay the
deficiency to landlord within 30 days after the delivery of such statement if
said amount is greater than one (1) months rent. Tenant shall have an additional
thirty (30) days to pay the balance. These obligations shall survive termination
of the lease.

         5.4      Additional Rent. Amounts payable by tenant according to this
Article 5 will be payable as rent, without deduction or offset. If tenant fails
to pay any amounts due according to this Article 5. landlord will have all the
rights and remedies available to it on account of tenant's failure to pay rent.

         (c)      Such other insurance as landlord reasonably determines from
time to time.

determined by landlord, based on coverages carried by prudent owners of
comparable buildings in the vicinity of the project.

         6.2      Tenant's Insurance. At all times during the term, tenant will
carry and maintain, at tenant's expense, the following insurance, in the amounts
specified below or such other amounts as landlord may from time to time
reasonably request, with insurance companies and on forms satisfactory to
landlord (in all events, such carrier shall be licensed to do business in the
State of Maryland and shall have a Best Guide Rating of at least A+):

         (a)      Commercial general liability insurance against any and all
claims for bodily injury and property damage occurring in. or about the Premises
arising out of Tenant's use and occupancy of the Premises. Such insurance shall
have a combined single limit of not less than One Million Dollars ($1.000.000)
per occurrence with Two Million Dollars ($2.000.000) aggregate limit. In no
event shall the limits of such insurance be considered as limiting the liability
of Tenant under this lease.

         (b)      Insurance covering all of tenant's furniture, fixtures,
equipment, and any other personal property owned and used in tenant's business
and found in, on, or about the project, and any Leasehold improvements to the

in an amount not less than the full replacement cost. Properly forms will

physical loss." All policy proceeds will be used for the repair or replacement
of the property damaged or destroyed.

         (c)      Worker's compensation insurance insuring against and
satisfying tenant's obligations and liabilities under the worker's compensation
laws of the stale in which the premises arc located, including employer's
liability insurance in the limits required by the laws of the state in which the
project is located.

         6.3      Forms of Policies. Certificates of insurance, together with
copies of the endorsements, when applicable, naming landlord and any others
specified by landlord as additional insureds, will be delivered to landlord
prior to tenant's entering the premises and from time to time at least 10 days
prior to the expiration of the term of each such policy. All such policies
maintained by tenant will provide that they may not be terminated nor may
coverage be reduced except after 30 days' prior written notice to landlord. All
commercial general liability and property policies maintained by tenant will be
written as primary policies, not contributing with and not supplemental to the
coverage that landlord may carry.

before the notice date or (2) tenant may cancel this Lease as of the date of
such damage by written notice given to the landlord within 10 days after

such 120-day period. If neither landlord nor tenant so elects to cancel this
Lease, landlord will diligently proceed to repair the building and premises and

(c) above, if the premises or the building are damaged by uninsured casualty, of

damage to the premises or the building, landlord will have the option to repair
such damage or cancel this Lease as of the date of such casualty by written
notice to tenant on or before the notice date.

         18.5     If any such damage by fire or other casualty is the result of

contractors, employees, or invitees, there will be no abatement of monthly rent

terminate this Lease on account of any damage to the premises, the building, or

self-operative and no further instrument of subordination will be required in
order to effect it. Notwithstanding the foregoing, tenant will execute,
acknowledge, and deliver to landlord, within 10 days after written demand by
landlord, such documents as may be reasonably requested by landlord or the
holder of any superior lien to confirm or effect any such subordination.

         19.2     Attornment and Nondisturbance. Tenant agrees that in the event

holder of a superior lien of the remedies provided for by law or by such
superior lien, tenant will, upon request of any person or party succeeding to
the interest of landlord as a result of such enforcement, automatically become
the tenant of and attorn to such successor in interest without change in the
terms or provisions of this Lease. Such successor in interest will not be bound
by:

         (a)      Any payment of rent for more than one month in advance, except
prepayments in the nature of security for the performance by tenant of its
obligations under this Lease;

such successor in interest succeeded to landlord's interest: or

         (c)      Any Security Deposit, except to the extent delivered to such

Upon request by such successor in interest and without cost to landlord or such
successor in interest, tenant will, within 10 days after written demand,
execute, acknowledge, and deliver an instrument confirming the attornment, so
long as such instrument provides that such successor in interest will not
disturb tenant in its use of the premises in accordance with this Lease.

Article 20. Tenant shall deliver to Landlord a key with which to unlock all
doors in, on, or about the premises (excluding tenant's vaults, safes, and
similar areas designated in writing by tenant in advance). Landlord will have
the right to use any and all means landlord may deem proper to open doors in and
to the premises in an emergency in order to obtain entry to the premises,
provided that landlord will promptly repair any damages caused by any forced
entry. Any entry to the premises by landlord in accordance with this Article 20
will not be construed or deemed to be a forcible or unlawful entry into or a
detainer of the premises or an eviction, actual or constructive, of tenant from
the premises or any portion of the premises, nor will any such entry entitle
tenant to damages or an abatement of monthly rent, additional rent, or other
charges that this Lease requires tenant to pay.

or agents by reason of any such claim for which tenant has indemnified landlord,
tenant, upon written notice from landlord, will defend the same at tenant's
expense, with counsel reasonably satisfactory to landlord.

liquidated damages or a payment of the monthly rent due for the last month of
the term. If tenant fully, faithfully, and timely performs every provision of
this Lease to be performed by it, the security deposit or any balance of the
security deposit will be returned to tenant within 60 days after the expiration
of the term. Landlord may deliver the funds deposited under this Lease by tenant

such time landlord will have no further liability to tenant with respect to the
security deposit.

landlord, in its reasonable discretion, may determine, and landlord may collect
and receive the rent. Landlord will in no way be responsible or liable for any
failure to relet the premises, or any part of the premises, or for any failure
to collect any rent due upon such reletting. No such reentry or taking
possession of the premises by landlord will be construed as an election on
landlord's part to terminate this Lease unless a written notice of such
intention is given to tenant. No written notice from landlord under this Section
or under a forcible or unlawful entry and detainer statute or similar law will
constitute an election by landlord to terminate this Lease unless such notice
specifically so states. Landlord reserves the right following any such reentry
or reletting to exercise its right to terminate this Lease by giving tenant such
written notice in which event this Lease will terminate as specified in such
notice.

         25.3     Certain Damages. If that landlord does not elect to terminate
this Lease as permitted in Section 25.2(a), but on the contrary elects to take
possession as provided in Section 25.2(b), tenant will pay to landlord monthly
rent and other sums as provided in this Lease that would be payable under this
Lease if such repossession had not occurred, less the net proceeds, if any, of
any reletting of the premises after deducting all of landlord's reasonable
expenses in connection with such reletting, including without limitation all
repossession costs, brokerage commissions, attorneys' fees, expenses of
employees, alteration and repair costs, and expenses of preparation for

                                       10
<PAGE>

such reletting. If, in connection with any reletting, the new Lease term extends
beyond the existing term, or the premises covered by such new Lease include
other premises not part of the premises, a fair apportionment of the rent
received from such reletting and the expenses incurred in connection with such
reletting as provided in this Section will be made in determining the net
proceeds from such reletting, and any rent concession will be equally
apportioned over the term of the new Lease. Tenant will pay such rent and other
sums to landlord monthly on the day on which the monthly rent would have been
payable under this Lease if possession had not been retaken, and landlord will
be entitled to receive such rent and other sums from tenant on each such day.

         25.4     Continuing Liability After Termination. If this Lease is
terminated on account of the occurrence of an event of default, tenant will
remain liable to landlord for damages in an amount equal to monthly rent and
other amounts that would have been owing by tenant for the balance of the term,
had this Lease not been terminated, less the net proceeds, if any, of any
reletting of the premises by landlord subsequent to such termination, after
deducting all of landlord's expenses in connection with such reletting,
including without limitation the expenses enumerated in Section 25.3. Landlord
will be entitled to collect such damages from tenant monthly on the day on which
monthly rent and other amounts would have been payable under this Lease if this
Lease had not been terminated, and landlord will be entitled to receive such
monthly rent and other amounts from tenant on each such day. Alternatively, at
the option of landlord, if this Lease is so terminated, landlord will be
entitled to recover from tenant as damages and not as a penalty:

         (a)      The worth at the time of award of the unpaid rent that had
been earned at the time of termination;

         (b)      The worth at the time of award of the amount by which the
unpaid rent for the balance of the term of this Lease (had the same not been so
terminated by landlord) after the time of award exceeds the amount of such
rental loss that tenant proves could be reasonably avoided:

         (c)      Any other amount necessary to compensate landlord for all the
detriment proximately caused by tenant's failure to perform its obligations
under this Lease or which in the ordinary course of things would be likely to
result therefrom.

The "worth at the time of award" of the amounts referred to in clause (a) is
computed by adding interest at the per annum interest rate described in 26.18 on
the date on which this Lease is terminated from the date of termination until
the time of the award. The "worth at the time of award" of the amount referred
to in clause (b) above is computed by discounting such amount at the rate of
12%.

         25.5     Cumulative Remedies. Any suit or suits for the recovery of the
amounts and damages set forth in Sections 25.3 and 25.4 may be brought by
landlord, from time to time, at landlord's election, and nothing in this Lease
will be deemed to require landlord to await the date upon which this Lease or
the term would have expired had there occurred no event of default. Each right
and remedy provided for in this Lease is cumulative and is in addition to every
other right or remedy provided for in this Lease or now or after the Lease date
existing at law or in equity or by statute or otherwise, and the exercise or
beginning of the exercise by landlord of any one or more of the rights or
remedies provided for in this Lease or now or after the Lease date existing at
law or in equity or by statute or otherwise will not preclude the simultaneous
or later exercise by landlord of any or all other rights or remedies provided
for in this Lease or now or after the Lease date existing at law or in equity or
by statute or otherwise. All costs incurred by landlord in collecting any
amounts and damages owing by tenant pursuant to the provisions of this Lease or
to enforce any provision of this Lease, including reasonable attorneys' fees
from the date any such matter is turned over to an attorney, whether or not one
or more actions are commenced by landlord, will also be recoverable by landlord
from tenant.

         25.6     Waiver of Redemption. Tenant waives any right of redemption
arising as a result of landlord's exercise of its remedies under this Article
25.

ARTICLE 26 - MISCELLANEOUS

         26.1     Joint and Several Liability. If tenant is composed of more
than one party, each signatory will be jointly and severally liable with each
other signatory for payment and performance according to this Lease. The act
of written notice to or from, refund to, or signature of any such signatory to
this Lease (including without limitation modifications of this Lease made by
fewer than all such signatories) will bind every other signatory as though every
other signatory had so acted, or received or given the written notice or refund,
or signed.

         26.2     No Construction Against Drafting Party. Landlord and tenant
acknowledge that each of them and their counsel have had an opportunity to
review this Lease and that this Lease will not be construed against landlord
merely because landlord has prepared it.

         26.3     Time of the Essence. Time is of the essence of each and every
provision of this Lease.

         26.4     No Recordation. Tenant's recordation of this Lease or any
memorandum or short form of it will be void and a default under this Lease.

         26.5     No Waiver. The waiver by landlord of any agreement, condition,
or provision contained in this Lease will not be deemed to be a waiver of any
subsequent breach of the same or any other agreement, condition, or provision
contained in this Lease. The subsequent acceptance of rent by landlord will not
be deemed to be a waiver of any preceding breach by tenant of any agreement,
condition, or provision of this Lease, other than the failure of tenant to pay
the particular rent so accepted, regardless of landlord's knowledge of such
preceding breach at the time of acceptance of such rent.

                                       11
<PAGE>

         26.6     Limitation on Recourse. Tenant specifically agrees to look
solely to landlord's interest in the project for the recovery of any judgments
from landlord. It is agreed that landlord (and its members officers, directors,
and employees) will not be personally liable for any such judgments. The
provisions contained in the preceding sentences are not intended to and will not
limit any right that tenant might otherwise have to obtain injunctive relief
against landlord or relief in any suit or action in connection with enforcement
or collection of amounts that may become owing or payable under or on account of
insurance maintained by landlord.

         26.7     Estoppel Certificates. At any time, but within 10 days after
prior written request by landlord, tenant will execute, acknowledge, and deliver
to landlord, promptly upon request, a certificate certifying (a) that this Lease
is unmodified and in full force and effect or, if there have been modifications,
that this Lease is in full force and effect, as modified, and stating the date
and nature of each modification; (b) the date, if any, to which rent and other
sums payable under this Lease have been paid; (c) that no written notice of any
default has been delivered to landlord which default has not been cured, except
as to defaults specified in said certificate: (d) that there is no event of
default under this Lease or an event which, with notice or the passage of time,
or both, would result in an event of default under this Lease, except for
defaults specified in said certificate; and (e) such other matters as may be
reasonably requested by landlord. Any such certificate may be relied upon by any
prospective purchaser or existing or prospective mortgage or beneficiary under
any deed of trust of the project. Tenant's failure to deliver such a certificate
within such time will be conclusive evidence of the matters set forth in it.

         26.8     Waiver of Jury Trial. Landlord and tenant hereby waive trial
by jury in any action, proceeding, or counterclaim brought by either of the
parties to this Lease against the other on any matters whatsoever arising out of
in any way connected with this Lease, the relationship of landlord and tenant,
tenant's use or occupancy of the premises, or any other claims (except claims
for personal injury or property damage), and any emergency statutory or any
other statutory remedy.

         26.9     Holding Over. Tenant will have no right to remain in
possession of all or any part of the premises after the expiration of the term.
If tenant remains in possession of all or any part of the premises after the
expiration of the term, with the express or implied consent of the landlord: (a)
such tenancy will be deemed to be a periodic tenancy from month-to-month only;
(b) such tenancy will not constitute a renewal or extension of this Lease for
any further term: and (c) such tenancy may be terminated by landlord upon the
earlier of 30 days' prior written notice or the earliest date permitted by law.
In such event, monthly rent will be increased to an amount equal to 125% for the
first sixty (60) days of the holdover then 151% thereafter of the monthly rent
payable during the last month of the term, and any other sums due under this
Lease will be payable in the amount and at the times specified in this Lease.
Such month-to-month tenancy will be subject to every other term, condition, and
covenant contained in this Lease.

         26.10    Notices. Any notice required under this Lease must be in
writing and will be deemed to have been given when personally delivered, sent by
facsimile with receipt acknowledged, deposited with any nationally recognized
overnight, carrier that routinely issues receipts, or deposited in any
depository regularly maintained by the United States Postal Service, postage
prepaid, certified mail, return receipt requested, addressed to the party for
whom it is intended all its address set forth in Article 1. Landlord or Tenant
may change its address for purposes of receipt of any such notice by giving the
other party written notice pursuant to this section.

         26.11    Severability. If any provision of this Lease proves to be
illegal, invalid, or unenforceable, the remainder of this Lease will not be
affected by such finding, and in lieu of each provision of this Lease that is
illegal, invalid, or unenforceable provision as may be possible and be legal,
valid, and enforceable.

         26.12    Written Amendment Required. No amendment, alteration,
modification of, or addition to the Lease will be valid or binding unless
expressed in writing and signed by landlord and tenant. Tenant agrees to make
any modifications of the terms and provisions of this Lease required or
requested by any lending institution providing financing for the building, or
project, as the case may be, provided that no such modifications will materially
adversely affect tenant's rights and obligations (including rent or additional
rent) under this Lease.

         26.13    Entire Agreement. This Lease and exhibits contains the entire
agreement between landlord and tenant. No promises or representations, except as
contained in this Lease, have been made to tenant.

         26.14    Notice of Landlord's Default. In the event of any alleged
default in the obligation of landlord under this Lease, tenant will deliver to
landlord written notice listing the reasons for landlord's default and landlord
will have 30 days following receipt of such notice to cure such alleged default
or, in the event the alleged default cannot reasonably be cured within a 30-day
period, to commence action and proceed diligently to cure such alleged default.
A copy of such notice to landlord will be sent to any holder of a mortgage or
other encumbrance on the building or project of which tenant has been notified
in writing, and any such holder will also have the same time periods to cure
such alleged default.

         26.15    Authority. Tenant and the party executing this Lease on behalf
of tenant represent to landlord that such party is authorized to do so by
requisite action of the board of directors or partners, as the case may be, and
agree upon request to deliver to landlord a resolution or similar document to
that effect.

         26.16    Brokers. Landlord and tenant respectively represent and
warrant to each other that neither of them has consulted or negotiated with any
broker or finder with regard to the premises except that broker named in Article
1. Landlord will pay fees or commissions due the broker listed in Article 1.
Tenant and Landlord will indemnify the other against and hold the other harmless
from any claims for fees or commissions from anyone with whom has consulted or
negotiated with regard to the premises except the broker.

         26.17    Governing Law. This Lease will be governed by the laws of the
State of Maryland.

         26.18    Late Payments. Any rent that is not paid when due will accrue
interest at the rate of 12% per annum from the date on which it was due until
the date on which it is paid in full with accrued interest.

         26.19    Tax Credits. Landlord is entitled to claim all tax credits and
depreciation attributable to Leasehold improvements in the premises. Promptly
after landlord's demand, landlord and tenant will prepare a detailed list of the
Leasehold improvements and Fixtures and their respective costs for which
landlord or tenant has paid. Landlord will be entitled to all credits and
depreciation for those items for which landlord has paid by means of any tenant
finish allowance or otherwise. Tenant will be entitled to any tax credits and
depreciation for all items for which tenant has paid with funds not provided by
landlord.

         26.20    Landlord's Fees. Whenever tenant requests landlord to take any
action or give any consent required or permitted under this Lease, tenant will
reimburse landlord for all of landlord's reasonable costs incurred in reviewing
the proposed action or consent, including without limitation reasonable
attorneys', engineers' or architects' fees, within 30 days after landlord's
delivery to tenant of a statement of such costs. Tenant will be obligated to
make such reimbursement without regard to whether landlord consents to any such
proposed action.

         26.21    Tenant shall have the right to place a sign on the exterior of
the building. Said design of sign and method of installations shall be approved
