contained herein, Landlord hereby leases the Premises to Tenant, and Tenant 
hereby leases the Premises from Landlord, for the Term and upon the terms and 
conditions hereinafter provided. As an appurtenance to the Premises, Tenant 
shall have the non-exclusive right, together with other tenants of the 
Building and their Agents, to use the Common Area. Landlord shall retain 
absolute dominion and control over the Common Area and shall operate and 
maintain the Common Area in such manner as Landlord, in its sole discretion, 
shall determine; provided, however, such exclusive right shall not operate to 
prohibit Tenant from its use of the Premises for the Permitted Use. Landlord 
expressly reserves the right permanently to change, modify or eliminate, or 
temporarily to close, any portion of the Common Area. The Premises are leased 
subject to, and Tenant agrees not to violate, all present and future 
covenants, conditions and restrictions of record which affect the Building.

          3.2  LANDLORD'S RESERVATIONS.  In addition to the other rights of 
Landlord under this Lease, Landlord reserves the right (i) to change the 
street address and/or name of the Building, (ii) to install, erect, use, 
maintain and repair mains, pipes, conduits and other such facilities to serve 
the Building's tenants in and through the Premises, (iii) to grant to anyone 
the exclusive right to conduct any particular business or undertaking in the 
Building, (iv) to establish a condominium regime for the Building, the Land 
and/or the Common Area and to include the Premises therein and (v) to control 
the use of the roof and exterior walls of the Building for any purpose. 
Landlord may exercise any or all of the foregoing rights without being deemed 
to be guilty of an eviction, actual or constructive, or a disturbance or 
interruption of the business of Tenant or Tenant's use or occupancy of the 
Premises.

ARTICLE 4:  TERM

          4.1  COMMENCEMENT AND EXPIRATION DATES.  The Term shall commence on 
the Commencement Date and expire at midnight on the Expiration Date. If 
Tenant uses or accepts the Premises before the date set forth in Article 1 as 
the Commencement Date, then the Commencement Date shall be the date upon 
which Tenant uses or accepts the Premises (e.g. by the moving of any 
furnishings or other personalty into the Premises). In such event, the 
Expiration Date shall be adjusted accordingly so that the period of the Term 
is not changed. If requested by Landlord, Tenant shall within fifteen (15) 
days of such request sign a declaration acknowledging


                                      4


the Commencement Date and the Expiration Date in the form attached hereto and 
made a part hereof as EXHIBIT E.

          4.2  DELAYED POSSESSION.  In the event that Landlord is unable to 
deliver possession of the Premises to Tenant on the Commencement Date set 
forth in Article 1, Landlord shall not be liable or responsible for any 
claims, damages or losses arising in connection with such delay in 
possession, and Tenant shall not be excused or released from any obligation 
under this Lease as a result of any delay in possession of the Premises.

ARTICLE 5:  RENT

          5.1  BASE RENT.  Tenant shall pay to Landlord the Base Rent as 
specified in Section 1.6. Base Rent shall be payable in equal monthly 
installments, in advance, without demand, notice, deduction, offset or 
counterclaim, on or before the first day of each and every calendar month 
during the Term; provided, however, that the installment of the Base Rent 
payable for the first full calendar month of the Term (and, if the 
Commencement Date occurs on a date other than on the first day of a calendar 
month, Base Rent prorated from such date until the first day of the following 
month) shall be due and payable on the full execution and delivery of this 
Lease. Tenant shall pay the Base Rent, by good check or in lawful currency of 
the United States of America, to Landlord at Landlord's Address, or to such 
other address or in such other manner as Landlord from time to time specifies 
by written notice to Tenant. Any payment made by Tenant to Landlord on 
account of Base Rent may be credited by Landlord to the payment of any late 
charges then due and payable and to any Base Rent then past due before being 
credited to Base Rent currently due.

          5.2  ADDITIONAL RENT.  [INTENTIONALLY DELETED]

ARTICLE 6:  SECURITY DEPOSIT

          Simultaneously with the execution of this Lease, Tenant shall 
deposit the Security Deposit with Landlord, which shall be held by Landlord, 
without obligation for interest, as security, for the performance of Tenant's 
obligations and covenants under this Lease. It is expressly understood and 
agreed that such deposit is not an advance rental deposit or a measure of 
Landlord's damages in case of an Event of Default. If an Event of Default 
shall occur or if Tenant fails to surrender the Premises in the condition 
required by this Lease, Landlord shall have the right (but not the 
obligation), and without prejudice to any other remedy which Landlord may 
have on account thereof, to apply all or any portion of the Security Deposit 
to cure such default or to remedy the condition of the Premises. If Landlord 
so applies the Security Deposit or any portion thereof before the Expiration 
Date or earlier termination of this Lease, Tenant shall deposit with 
Landlord, upon demand, the amount necessary to restore the Security


                                      5


Deposit to its original amount. If Landlord shall sell or transfer its 
interest in the Building, Landlord shall have the right to transfer the 
Security Deposit to such purchaser or transferee, in which event Tenant shall 
look solely to the new landlord for the return of the Security Deposit, and 
Landlord thereupon shall be released from all liability to Tenant for the 
return of the Security Deposit. Although the Security Deposit shall be deemed 
the property of Landlord, any remaining balance of the Security Deposit shall 
be returned to Tenant at such time after the Expiration Date or earlier 
termination of this Lease that all of Tenant's obligations under this Lease 
have been fulfilled. Landlord shall conduct a "Post Move-Out Inspection" of 
the Premises within fifteen (15) days after the Expiration Date or earlier 
termination of this Lease.

ARTICLE 7:  OPERATING EXPENSES [INTENTIONALLY DELETED]

ARTICLE 8:  TAXES [INTENTIONALLY DELETED]

ARTICLE 9:  PARKING

          9.1  PARKING SPACES.  Tenant and its Agents shall have the right to 
use the Parking Facilities in accordance with the terms and provisions of 
EXHIBIT C attached hereto. If Landlord shall determine that Tenant and its 
Agents are using parking spaces in violation of the terms of EXHIBIT C or if 
Tenant defaults under any lease or other agreement with the Parking Manager 
(as defined in EXHIBIT C) for use of Parking Facilities and Tenant fails to 
remedy such default within fifteen (15) days following written notice from 
Landlord or Parking Manager, such default shall be an Event of Default giving 
rise to the remedies set forth in Article 22.

          9.2  CHANGES TO PARKING FACILITIES.  Landlord shall have the right, 
from time to time, without Tenant's consent, to change, alter, add to, 
temporarily close or otherwise affect the Parking Facilities in such manner 
as Landlord, in its sole discretion, deems appropriate including, without 
limitation, the right to designate reserves spaces available only for use by 
one or more tenants (however, in such event, those parking space shall still 
be deemed Common Area for the purpose of the definition of Operating 
Expenses), provided that, except in emergency situations or situations beyond 
Landlord's control, Landlord shall provide alternative Parking Facilities.

ARTICLE 10:  USE

          Tenant shall occupy the Premises solely for the Permitted Use. The 
Premises shall not be used for any other purpose, or for any use that would 
cause the Premises to be deemed a "place of public accommodation" under the 
Americans With Disabilities Act of 1990, without the prior written consent of 
Landlord. Tenant shall


                                      6


comply, at Tenant's expense, with (i) all present and future laws, 
ordinances, regulations and orders of the United States of America, the 
Commonwealth of Virginia and any other public or quasi-public federal, state 
or local authority having jurisdiction over the Premises, and (ii) any 
reasonable requests of Mortgagee or any insurance company providing coverage 
with respect to the Premises. Tenant shall not use or occupy the Premises in 
any manner that is unlawful or dangerous or that shall constitute waste, 
unreasonable annoyance or a nuisance to Landlord or the other tenants of the 
Building.

ARTICLE 11:  ASSIGNMENT AND SUBLETTING

          11.1 ASSIGNMENT.  Tenant shall not assign, transfer, mortgage or 
otherwise encumber this Lease or any part thereof, nor shall any assignment 
or transfer of this Lease be effected by operation of law or otherwise, 
without the prior written consent of Landlord which may be granted or 
withheld in Landlord's sole discretion. For purposes of the foregoing 
prohibitions, a transfer at any one time or from time to time of twenty 
percent (20%) or more of an interest in Tenant (whether stock, partnership 
interest or other form of ownership or control) by any person(s) or 
entity(ties) having an interest in ownership or control of Tenant at the Date 
of Lease shall be deemed to be an assignment of this Lease.

          11.2 SUBLETTING.  Tenant shall not sublet or rent or permit a 
third party to occupy or use the Premises, or any part thereof, without the 
prior written consent of Landlord, which consent may be granted or withheld 
in Landlord's sole discretion.

          11.3 EFFECT.  If Landlord consents to the proposed assignment, 
transfers or subletting, the initial Tenant and any Guarantor shall remain 
liable under this Lease and the initial Tenant shall pay to Landlord any 
amount of rent or other sums directly or indirectly received by Tenant from 
any subtenant, assignee or transferee which exceeds the Rent. Any assignment, 
transfer, mortgage, encumbrance, or sublease without Landlord's written 
consent shall be voidable by Landlord and, at Landlord's election, constitute 
an Event of Default hereunder. Neither the consent by Landlord to any 
assignment, transfer, encumbrance or subletting nor the collection or 
acceptance by Landlord of rent from any assignee, subtenant or occupant shall 
be construed as a waiver or release of the initial Tenant or any Guarantor 
from the terms and conditions of this Lease or relieve Tenant or any 
subtenant, assignee or other party from obtaining the consent in writing of 
Landlord to any further assignment, transfer, encumbrance or subletting. 
Tenant hereby assigns to Landlord the rent and other sums due from any 
subtenant, assignee or other occupant of the Premises and hereby authorizes 
and directs each such subtenant, assignee or other occupant to pay such rent 
or other sums directly to Landlord; provided, however, that until the occur-


                                      7


rence of an Event of Default, Tenant shall have the license to continue 
collecting such rent and other sums from subtenants or other occupants, but 
not from assignees, who shall pay rent and other sums under this Lease 
directly to Landlord.

          11.4 SURRENDER.  Notwithstanding the foregoing, in the event of a 
proposed assignment or subletting, Landlord shall have the right, by notice 
to Tenant, to terminate this Lease in the event of an assignment as to all of 
the Premises and, in the event of a sublease, as to the subleased portion of 
the Premises, and to require that all or part, as the case may be, of the 
Premises be surrendered to Landlord for the balance of the Term.

ARTICLE 12:  MAINTENANCE AND REPAIR

          12.1 LANDLORD'S OBLIGATION.  As long as no Event of Default has 
occurred and is continuing, Landlord, at its sole cost and expense, shall 
keep and maintain in good repair and working order the Building, the Common 
Area, the mechanical and electrical systems of the Building, and the 
equipment within and serving the Premises and the Building (excluding 
Tenant's leasehold improvements in the Premises) that are required for the 
normal maintenance and operation of the Premises and the Building. Tenant 
shall immediately give Landlord written notice of any defect or need for 
repairs. After such notice, Landlord shall have a reasonable opportunity to 
repair or cure such defect. Landlord's liability with respect to any defects, 
repairs or maintenance for which Landlord is responsible under any of the 
provisions of this Lease shall be limited to the cost of such repairs or 
maintenance or the curing of such defect.

          12.2 TENANT'S OBLIGATION.  Tenant shall, at its own expense, 
maintain all of Tenant's leasehold improvements in the Premises and other 
real and personal property within the Premises in good condition, promptly 
making all necessary repairs and replacements. Tenant shall repair at its 
expense, any and all damage caused by Tenant or Tenant's agents, contractors 
or subcontractors to the Building, the Common Area, or the Premises, 
including equipment within and serving the Building, ordinary wear and tear 
excepted. Notwithstanding the foregoing, Tenant shall bear the cost of, but 
shall not itself perform without Landlord's prior consent, any such repairs 
which would affect the Building's structure or mechanical or electrical 
systems or which would be visible from the exterior of the Building or from 
any interior Common Area of the Building. Where Landlord performs such 
repairs, Tenant shall promptly pay to Landlord upon demand all costs incurred 
in connection therewith plus interest thereon at the Interest Rate from the 
demand date until paid. Without the prior written consent of the Landlord, 
Tenant shall not have access to the roof of the Building for any purpose 
whatsoever.


                                      8


          12.3 LANDLORD'S RIGHT TO MAINTAIN OR REPAIR.  If, within five (5) 
days following notice to Tenant, Tenant fails to commence to repair or 
replace any damage to the Premises or Building which is Tenant's obligation 
to perform, and diligently pursue timely completion of such repair and 
replacement. Landlord may, at its option, cause all required maintenance, 
repairs or replacements to be made. Tenant shall promptly pay Landlord all 
costs incurred in connection therewith plus interest thereon at the Interest 
Rate from the due date until paid.

ARTICLE 13:  ALTERATIONS

          13.1 ALTERATIONS.  Tenant shall not make or permit any Alterations 
without the prior written consent of Landlord, which consent may be granted 
or withheld in Landlord's sole discretion. Landlord may impose any reasonable 
conditions to its consent, including, without limitation, (i) delivery to 
Landlord of written and unconditional waivers of mechanic's and materialmen's 
liens as to the Premises, the Building and the Land for all work, labor and 
services to be performed and materials to be furnished, signed by all 
contractors, subcontractors, materialmen and laborers participating in the 
Alterations, (ii) prior approval of the plans and specifications and Tenant's 
contractor(s) with respect to the Alterations, (iii) supervision by 
Landlord's representative at Tenant's expense of the Alterations and (iv) 
delivery to Landlord of payment and performance bonds naming Landlord and 
Mortgagee as obligees. The Alterations shall conform to the requirements of 
Landlord's and Tenant's insurers and of the Federal, state and local 
governments having jurisdiction over the Premises, shall be performed in 
accordance with the terms and provisions of this Lease in a good and 
workmanlike manner befitting a first class office building and shall not 
adversely affect the value, utility or character of the Premises. If the 
Alterations are not performed as herein required, Landlord shall have the 
right, at Landlord's option, to halt any further Alterations, or to require 
Tenant to perform the Alterations as herein required or to require Tenant to  
return the Premises to its condition before such Alterations. Subject to 
Section 13.3 herein, all Alterations and fixtures, whether temporary or 
permanent in character, made in or upon the Premises either by Tenant or 
Landlord, will immediately become Landlord's property and, at the end of the 
Term will remain on the Premises without compensation to Tenant.

          13.2 LIENS.  Notwithstanding the foregoing, if any mechanic's or 
materialmen's lien is filed against the Premises, the Building or the Land 
for work claimed to have been done for, or materials claimed to have been 
furnished to or for the benefit of, Tenant, such lien shall be discharged of 
record by Tenant within ten (10) days by the payment thereof or the filing of 
any bond required by law. If Tenant shall fail to discharge any such lien, 
Landlord may (but shall not be obligated to) discharge the same, the cost of 
which shall be paid by Tenant within three (3) days of


                                      9


demand by Landlord. Such discharge by Landlord shall not be deemed to waive 
or release the default of Tenant in not discharging the same. Neither 
Landlord's consent to the Alterations nor anything contained in this Lease 
shall be deemed to be the agreement or consent of Landlord to subject 
Landlord's interest in the Premises, the Building or the Land to any 
mechanic's or materialmen's liens which may be filed in respect of the 
Alterations.

          13.3 REMOVAL OF ALTERATIONS.  Unless Landlord specifies at the time 
Landlord approves such Alterations that such Alterations shall be removed by 
Tenant, all or any part of the Alterations (including, without limitation, 
wall-to-wall carpet and wiring), whether made with or without the consent of 
Landlord, shall remain upon the Premises and be surrendered therewith at the 
Expiration Date or earlier termination of this Lease as the property of 
Landlord without disturbance, molestation or injury. If Landlord so requires 
the removal of all or part of the Alterations, Tenant, at its expense, shall 
repair any damage to the Premises or the Building caused by such removal 
before the expiration or termination of this Lease. If Tenant fails to remove 
such Alterations, then Landlord may (but shall not be obligated to) remove 
the same and the cost of such removal and repair of any damage caused by the 
same, together with any and all damages which Landlord may suffer and sustain 
by reason of the failure of Tenant to remove the same, shall be charged to 
Tenant and paid upon demand.

          13.4 LANDLORD ALTERATIONS.  Landlord shall have no obligation to 
make any Alterations in or to the Premises, the Building, the Common Area or 
the Land. Landlord hereby reserves the right, from time to time, to make 
Alterations to the Building, change the Building dimensions, erect additional 
stories thereon and attach other buildings and structures thereto, and to 
erect such scaffolding and other aids to construction as Landlord deems 
appropriate, and no such Alterations, changes, construction or erection shall 
constitute an eviction, constructive or otherwise, or permit Tenant any 
abatement of Rent or claim.

ARTICLE 14:  SIGNS

          No sign, advertisement or notice shall be inscribed, painted, 
affixed, placed or otherwise displayed by Tenant on any part of the Land or 
the outside or the inside (including, without limitation, the windows) of the 
Building or the Premises. Landlord shall, at Landlord's expense, place a 
Building-standard suite entry sign on the exterior of the Premises 
identifying Tenant's occupancy of the Premises, and shall provide 
identification of Tenant and its suite number on a main directory in the 
lobby on the first floor of the Building. Any other permitted signs shall be 
installed and maintained by Landlord at Tenant's sole expense. If any 
prohibited sign, advertisement or notice is nevertheless exhibited by Tenant, 
Landlord shall have the right to remove the same, and Tenant shall


                                      10


pay any and all expenses incurred by Landlord in such removal, together with 
interest thereon at the Interest Rate, upon demand. Landlord shall have the 
right to prohibit any sign, advertisement, notice or statement to the public 
by Tenant which, in Landlord's opinion, tends to impair the reputation of the 
Building or its desirability as a first class office building.

ARTICLE 15:  TENANT'S EQUIPMENT AND PROPERTY

          15.1 MOVING TENANT'S PROPERTY.  Any and all damage or injury to the 
Premises or the Building caused by moving the property of Tenant into or out 
of the Premises, or due to the same being on the Premises, shall be repaired 
by Landlord, at the expense of Tenant. Tenant shall promptly remove from the 
Common Area any of Tenant's furniture, equipment or other property there 
deposited.

          15.2 INSTALLING AND OPERATING TENANT'S EQUIPMENT.  Without first 
obtaining the written consent of Landlord, Tenant shall not install or 
operate in the Premises (i) any electrically operated equipment or other 
machinery, other than standard office equipment that does not require wiring, 
cooling or other service in excess of Building standards, (ii) any equipment 
of any kind or nature whatsoever which will require any changes, replacements 
or additions to, or changes in the use of, any water, heating, plumbing, air 
conditioning or electrical system of the Premises or the Building, or (iii) 
any equipment which causes the floor load to exceed the load limits set by 
Landlord for the Building. Landlord's consent to such installation or 
operation may be conditioned upon the payment by Tenant of additional 
compensation for any excess consumption of utilities and any additional power, 
wiring, cooling or other service (as determined in the sole discretion of 
Landlord) that may result from such equipment. Machines and equipment which 
cause noise or vibration that may be transmitted to the structure of the 
Building or to any space therein so as to be objectionable to Landlord or any 
other Building tenant shall be installed and maintained by Tenant, at its 
expense, on vibration eliminators or other devices sufficient to eliminate 
such noise and vibration.

ARTICLE 16:  RIGHT OF ENTRY

          Tenant shall permit Landlord or its Agents, at any time and without 
notice as to (i) and (ii) below and upon reasonable notice during normal 
business hours as to (iii) and (iv) below, to enter the Premises, without 
diminution of Rent, (i) to examine, inspect and protect the Premises and the 
Building, (ii) to make such alterations and repairs or perform such 
maintenance which in the sole judgment of Landlord may be deemed necessary 
or desirable, (iii) to exhibit the same to prospective purchasers of the 
Building or to present or future Mortgagees or (iv) to exhibit the same to 
prospective tenants during the last twelve (12) months of the Term.


                                      11


ARTICLE 17:  INSURANCE

          17.1 INSURANCE RATING.  Tenant shall not conduct or permit any 
activity, or place any equipment or material, in or about the Premises, the 
Building or the Common Area which will increase the rate of fire or other 
insurance on the Building or insurance benefitting any other tenant of the 
Building; and if any increase in the rate of insurance is stated by any 
insurance company or by the applicable insurance rating bureau to be due to 
any activity, equipment or material of Tenant in or about the Premises, the 
Building or the Common Area, such statement shall be conclusive evidence that 
the increase in such rate is due to the same and, as a result thereof, Tenant 
shall pay such increase to Landlord upon demand.

          17.2 LIABILITY INSURANCE.  Tenant shall, at its sole cost and 
expense, procure and maintain throughout the Term a commercial general 
liability policy insuring against claims, demands or actions for bodily 
injury, death, personal injury, and loss or damage to property arising out of 
or in connection with: (i) the Premises; (ii) the condition of the Premises; 
(iii) Tenant's operations in, maintenance and use of the Premises, Building 
and Common Area, and (iv) Tenant's liability assumed under this Lease. Such 
insurance shall have such combined single limit as reasonably required by 
Landlord from time to time, but in no event less than Two Million Dollars 
($2,000,000.00) per occurrence, on an occurrence basis, and shall be primary 
over any insurance carried by Landlord. Endorsements shall be obtained for 
cross-liability and contractual liability.

          17.3 INSURANCE FOR PERSONAL PROPERTY.  Tenant shall, at its sole 
cost and expense, procure and maintain throughout the Term a property 
insurance policy (written on an "All Risk" basis) insuring all of Tenant's 
personal property, including but not limited to equipment, furniture, 
fixtures, furnishings and leasehold improvements which are the responsibility 
of Tenant, for not less than the full replacement cost of said property. All 
proceeds of such insurance shall be used to repair or replace Tenant's 
property. In addition, Tenant shall, at its sole cost and expense, procure 
and maintain business interruption insurance in an amount not less than the 
Base Rent due hereunder.

          17.4 REQUIREMENTS OF INSURANCE COVERAGE.  All such insurance 
required to be carried by Tenant herein shall be with an insurance company 
licensed to do business in the Commonwealth of Virginia and rated not lower 
than A-XII in the A.M. Best Rating Guide. Such insurance (i) shall contain an 
endorsement that such policy shall remain in full force and effect 
notwithstanding that the insured has released its right of action against 
any party before the occurrence of a loss; (ii) shall name Landlord, 
Landlord's managing agent, the Parking Manager, and, at Landlord's request, 
any Mortgagee or ground lessor, as additional insured


                                      12


parties; and (iii) shall provide that the policy shall not be cancelled, 
failed to be renewed or materially amended without at least thirty (30) days' 
prior written notice to Landlord and, at Landlord's request, any Mortgagee. 
On or before the Commencement Date and, thereafter, not less than thirty (30) 
days before the expiration date of the insurance policy, an original of the 
policy (including any renewal or replacement policy) or a certified copy 
thereof, together with evidence satisfactory to Landlord of the payment of 
all premiums for such policy, shall be delivered to Landlord and, at 
Landlord's request, to any Mortgagee.

          17.5 WAIVER OF SUBROGATION.  Each party hereby releases the other 
party hereto from liability for any loss or damage to any building, structure 
or tangible personal property, or any resulting loss of income, or losses 
under worker's compensation laws and benefits, notwithstanding that such 
loss, damage or liability may arise out of the negligent or intentionally 
tortious act or omission of the other party or its agents, if such loss or 
damage is covered by insurance benefitting the party suffering such loss or 
damage or was required to be covered by insurance pursuant to this Lease. 
Each party hereto shall have a waiver of subrogation clause (providing that 
such waiver of right of recovery against the other party shall not impair the 
effectiveness of such policy or the insured's ability to recover thereunder) 
included in its said policies, and shall promptly notify the other in writing 
if such clause cannot be included in any such policy; if such waiver of 
subrogation clause shall not be available, then the foregoing waiver of right 
of recovery shall be void.

          17.6 SECURITY.  In the event that Landlord engages the services of 
a professional security system for the Building, it is understood that such 
engagement shall in no way increase Landlord's liability for occurrences 
and/or consequences which such a system is designed to detect or avert and 
that Tenant shall look solely to its insurer as set out above for claims for 
damages or injury to any person or property.

          17.7 LANDLORD'S INSURANCE.  Landlord shall procure and maintain 
throughout the Term fire and extended coverage insurance on the Building in 
such coverage and amounts as reasonably determined by Landlord in its prudent 
management of the Building and as necessary to satisfy the requirements of 
Landlord's Mortgagee, if any.

ARTICLE 18:  LANDLORD SERVICES AND UTILITIES

          18.1 ORDINARY SERVICES TO THE PREMISES.  As long as no Event of 
Default has occurred and is continuing, Landlord shall, at its sole cost and 
expense, furnish to the Premises throughout the Term (i) electricity, heating 
and air conditioning appropriate for the Permitted Use between 8:00 a.m. and 
6:00 p.m., Monday through Friday, and between 9:00 a.m. and 1:00 p.m. on 
Saturday (except for


                                      13


the following holidays: New Year's Day, Memorial Day, Independence Day, Labor 
Day, Thanksgiving Day and Christmas Day), (ii) reasonable janitorial service, 
(iii) regular trash removal from the Premises, (iv) hot and cold water from 
points of supply, (v) restrooms as required by applicable code, and (vi) 
elevator service, if there is an elevator in the Building, provided that 
Landlord shall have the right to remove such elevators from service as may be 
required for moving, freight or for servicing or maintaining the elevators or 
the Building. Landlord agrees to furnish landscaping and grounds maintenance 
and snow clearing for the areas used in common by the tenants of the 
Building. Landlord shall be under no responsibility or liability for failure 
or interruption in such services caused by breakage, accident, strikes, 
repairs or for any other cause or causes beyond the control of Landlord, nor 
in any event for any indirect or consequential damages; and failure or 
omission on the part of Landlord to furnish such service shall not be 
construed as an eviction of Tenant, nor work an abatement of Rent, nor 
render Landlord liable in damages, nor release Tenant from prompt fulfillment 
of any of the covenants under this Lease.

          18.2 AFTER-HOURS SERVICES TO THE PREMISES.  If Tenant requires or 
requests that the services to be furnished by Landlord (except Building 
standard electricity and elevator service) be provided during periods in 
addition to the periods set forth in Section 18.1, then Tenant shall obtain 
Landlord's consent thereto and, if such consent is granted, shall pay upon 
demand Landlord's additional expenses resulting therefrom. Landlord may, from 
time to time during the Term, set a per hour charge for after-hours service 
which shall include the cost of utility service, labor costs, administrative 
costs and a cost for depreciation of the equipment used to provide such 
after-hours service.

          18.3 UTILITY CHARGES.  All telephone and other utility service 
furnished to the Premises shall be paid for directly by Tenant except those 
furnished by Landlord as listed in Section 18.1 above. In the event that, or 
to determine whether, Tenant's use of utility services exceeds on a pro rata 
basis Building standard electricity, heating and air conditioning normally 
used by tenants in the Building, Landlord reserves the right separately to 
meter or monitor the utility services provided to the Premises. If Tenant's 
use of such utilities exceeds the normal use by other tenants in the 
Building, Landlord may charge Tenant for such excess use in accordance with 
Section 18.2 above, and the cost of any such meter shall be borne by Tenant.

ARTICLE 19:  LIABILITY OF LANDLORD

          19.1 NO LIABILITY.  Except where due to Landlord or its Agents' 
gross negligence or willful misconduct, Landlord and its Agents shall not be 
liable to Tenant or its Agents for, and Tenant, for itself and its Agents, 
does hereby release Landlord and its Agents from liability for, any damage, 
compensation or claim


                                      14


arising from (i) the necessity of repairing any portion of the Premises or 
the Building or the Common Area or any structural defects thereto, (ii) any 
interruption in the use of the Premises or the Common Area for any reason 
including any interruption or suspension of utility service, (iii) fire or 
other casualty or personal or property injury, damage or loss resulting from 
the use or operation (by Landlord, Tenant, or any other person whomsoever) of 
the Premises or the Building or the Common Area, (iv) the termination of this 
Lease, (v) robbery, assault or theft, or (vi) any leakage in the Premises or 
the Building from water, rain, snow or other cause whatsoever. No such 
occurrence shall give rise to diminution or abatement or Rent or constructive 
eviction. Notwithstanding the foregoing, any goods, automobiles, property or 
personal effects stored or placed by Tenant or its Agents in or about the 
Premises, the Building or the Common Area shall be at the sole risk of 
Tenant; Tenant hereby expressly waives its right to recover against Landlord 
and its Agents therefor. Tenant hereby waives any claim it might have against 
Landlord or its Agents for any consequential damages or business losses 
sustained by Tenant arising out of the loss or damage to any person or 
property of Tenant, or any interruption in the use of the Premises or the 
Common Area, for any reason. Tenant acknowledges its obligation to insure 
against such losses and damages.

          19.2 INDEMNITY.  Tenant shall indemnify, defend, protect and hold 
Landlord and its Agents harmless from and against any and all damage, claim, 
liability, cost or expense (including, without limitation, attorneys' or 
other professionals' fees) of every kind and nature (including, without 
limitation, those arising from any injury or damage to any person, property 
or business) incurred by or claimed against Landlord or its Agents, directly 
or indirectly, as a result of, arising from or in connection with (i) 
Tenant's or its Agents' use and occupancy of the Premises, the Building or 
the Common Area; (ii) Tenant's breach of any provision of this Lease; or 
(iii) any act, omission or negligence of Tenant or its Agents.

ARTICLE 20: RULES AND REGULATIONS

          Tenant and its Agents shall at all times abide by and observe the 
Rules and Regulations attached hereto as EXHIBIT D and any amendments thereto 
that may be promulgated from time to time by Landlord for the operation and 
maintenance of the Building and the Common Area and the Rules and Regulations 
shall be deemed to be covenants of the Lease to be performed and/or observed 
by Tenant. Nothing contained in this Lease shall be construed to impose upon 
Landlord any duty or obligation to enforce the Rules and Regulations, or the 
terms or provisions contained in any other lease, against any other tenant of 
the Building. Landlord shall not be liable to Tenant for any violation by any 
party of the Rules and Regulations or the terms of any other Building lease. 
If there is any inconsistency between this Lease and the Rules and Regu-


                                      15


lations, this Lease shall govern. Landlord reserves the right to amend and 
modify the Rules and Regulations as it deems necessary.

ARTICLE 21:  DAMAGE; CONDEMNATION

          21.1 DAMAGE TO THE PREMISES.  If the Premises shall be damaged by 
fire or other cause without the fault or negligence of Tenant or its Agents, 
Landlord shall diligently and as soon as practicable after such damage occurs 
(taking into account the time necessary to effect a satisfactory settlement 
with any insurance company involved) repair such damage at the expense of 
Landlord; provided, however, that Landlord's obligation to repair such damage 
shall not exceed the proceeds of insurance available to Landlord (reduced by 
any proceeds retained pursuant to the rights of Mortgagee). Notwithstanding 
the foregoing, (i) if more than twenty percent (20%) of the floor area of the 
Premises or the Building is damaged or destroyed, or (ii) if the Premises or 
the Building is damaged by fire or other cause to such an extent that, in 
Landlord's sole judgment, the damage cannot be substantially repaired within 
one hundred eighty (180) days after the date of such damage, or (iii) if the 
Premises are damaged during the last six (6) months of the Term, then 
Landlord may terminate this Lease by notice to Tenant within sixty (60) days 
from the date of such damage. During the period that Tenant is deprived of 
the use of the damaged portion of the Premises, and provided such damage is 
not the consequence of the fault or negligence of Tenant or its Agents, Base 
Rent shall be reduced by the ratio that the rentable square footage of the 
Premises damaged bears to the total rentable square footage of the Premises 
before such damage. All injury or damage to the Premises or the Building 
resulting from the fault or negligence of Tenant or its Agents shall be 
repaired by Tenant, at Tenant's expense, and Rent shall not abate. If Tenant 
shall fail to do so or if Landlord shall so elect, Landlord shall have the 
right to make such repairs, and any expense so incurred by Landlord, 
together with interest thereon at the Interest Rate, shall be paid by Tenant 
upon demand. Notwithstanding anything herein to the contrary, Landlord shall 
not be required to rebuild, replace or repair any non-standard tenant 
improvements, tenant extras or Alterations or any personal property of Tenant.

          21.2 CONDEMNATION.  If the whole or a Substantial Part of the 
Premises or the Building shall be taken or condemned by any governmental or 
quasi-governmental authority for any public or quasi-public use or purpose 
(including, without limitation, sale under threat or such a taking), then the 
Term shall cease and terminate as of the date when title vests in such 
governmental or quasi-governmental authority, and Rent shall be prorated to 
the date when title vests in such governmental or quasi-governmental 
authority. If less than a Substantial Part of the Premises is taken or 
condemned by any governmental or quasi-governmental authority for any public 
or quasi-public use or purpose (including, without limitation, sale under 
threat of such a taking), Base Rent


                                      16


shall be reduced by the ratio that the portion so taken bears to the 
rentable square footage of the Premises before such taking, effective as of 
the date when title vests in such governmental or quasi-governmental 
authority, and this Lease shall otherwise continue in full force and effect. 
Tenant shall have no claim against Landlord (or otherwise) as a result of 
such taking; and Tenant hereby agrees to make no claim against the condemning 
authority for any portion of the amount that may be awarded as compensation 
or damages as a result of such taking; provided, however, that Tenant may, to 
the extent allowed by law, claim an award for moving expenses and for the 
taking of any of Tenant's property (other than its leasehold interest in the 
Premises) which does not, under the terms of this Lease, become the property 
of Landlord at the termination hereof, as long as such claim is separate and 
distinct from any claim of Landlord and does not diminish Landlord's award. 
Tenant hereby assigns to Landlord any right and interest it may have in any 
award for its leasehold interest in the Premises.

ARTICLE 22:  DEFAULT

          22.1 EVENTS OF DEFAULT.  Each of the following shall constitute an 
Event of Default: (i) Tenant fails to pay Rent when due and such failure 
continues for five (5) days after notice from Landlord; provided that no such 
notice shall be required if at least two such notices shall have been given 
during the same Lease Year and, in such event, it shall be deemed an Event of 
Default if such failure continues for five (5) days after such Rent is due; 
(ii) Tenant fails to observe or perform any other term, condition or covenant 
herein binding upon or obligating Tenant within fifteen (15) days after 
notice from Landlord, or, if such failure cannot reasonably be corrected 
within fifteen (15) days, if Tenant does not begin to correct the failure 
within fifteen (15) days after such notice and/or does not thereafter 
diligently pursue the correction of such failure to completion within 
thirty (30) days after said notice from Landlord; (iii) Tenant abandons or 
vacates the Premises; (iv) Tenant makes or consents to a general assignment 
for the benefit of creditors or a common law composition of creditors, or a 
receiver of the Premises or all or substantially all of Tenant's assets is 
appointed, or (v) Tenant files a voluntary petition in any bankruptcy or 
insolvency proceeding, or an involuntary petition in any bankruptcy or 
insolvency proceeding is filed against Tenant and is not discharged by Tenant 
within sixty (60) days.

          22.2 LANDLORD'S REMEDIES.  Upon the occurrence of an Event of 
Default, Landlord, at its option, without further notice or demand to Tenant, 
in addition to all other rights and remedies provided in this Lease, at law 
or in equity, shall have the right to elect any or all of the following 
remedies:


                                      17



          (i)    Terminate this Lease and Tenant's right of possession of the 
Premises, and recover all damages to which Landlord is entitled under law, 
specifically including but without limitation, all of Landlord's expenses of 
reletting (including, without limitation, rental concessions to new tenants, 
repairs, Alterations, legal fees and brokerage commissions). If Landlord 
elects to terminate this Lease, every obligation of the parties shall cease 
as of the date of such termination, except that Tenant shall remain liable 
for payment of Rent and performance of all other terms and conditions of this 
Lease to the date of termination.

          (ii)   Terminate Tenant's right of possession of the Premises 
without terminating this Lease, in which event Landlord may, but shall not be 
obligated to, relet the Premises, or any part thereof, for the account of 
Tenant, for such rent and term and upon such other conditions as are 
acceptable to Landlord. For purposes of such reletting, Landlord is authorized 
to redecorate, repair, alter and improve and Premises to the extent necessary 
in Landlord's sole discretion. Until Landlord relets the Premises, Tenant 
shall remain obligated to pay Rent to Landlord as provided in this Lease. If 
and when the Premises are relet and if a sufficient sum is not realized from 
such reletting after payment of all Landlord's expenses of reletting 
(including, without limitation, rental concessions to new tenants, repairs, 
Alterations, legal fees and brokerage commissions) to satisfy the payment of 
Rent due under this Lease for any month, Tenant shall pay Landlord any such 
deficiency upon demand. Tenant agrees that Landlord may file suit to recover 
any sums due Landlord under this Section from time to time and that such suit 
or recovery of any amount due Landlord shall not be any defense to any 
subsequent action brought for any amount not previously reduced to judgment 
in favor of Landlord;

          (iii)  Terminate this Lease and Tenant's right of possession of the 
Premises, and recover from Tenant the net present value of the Rent due from 
the date of termination until the Expiration Date, discounted at the lesser 
of the Interest Rate as of the date of termination or six percent (6%) per 
annum.

          (iv)   Re-enter and repossess the Premises and remove all persons 
and effects therefrom, by summary proceeding, ejectment or other legal action 
or by using such force as may be necessary. Landlord shall have no liability 
by reason of any such re-entry, repossession or removal; and/or

          (v)    Recover from Tenant, to the extent permitted under the laws 
of the Commonwealth of Virginia, the value and/or cost of all concessions to 
Tenant under this Lease, if any.

     22.3  Rights Upon Possession.  If Landlord takes possession pursuant to 
this Article, with or without terminating this


                                       18



Lease, Landlord may, at its option, enter into the Premises, remove Tenant's 
Alternations, signs, personal property, equipment and other evidences of 
tenancy, and store them at Tenant's risk and expense or dispose of them as 
Landlord may see fit, and take and hold possession of the Premises; provided, 
however, that if Landlord elects to take possession only without terminating 
this Lease, such entry and possession shall not terminate this Lease or 
release Tenant or any Guarantor, in whole or in part, from the obligation to 
pay the Rent reserved hereunder for the full Term or from any other 
obligation under this Lease or any guaranty thereof.

     22.4  No Waiver.  If Landlord shall institute proceedings against Tenant 
and a compromise or settlement thereof shall be made, the same shall not 
consititute a waiver of any other covenant, condition or agreement herein 
contained, nor of any of Landlord's rights hereunder. No waiver by Landlord 
of any breach shall operate as a waiver of such covenant, condition or 
agreement, or operate as a waiver of such covenant, condition or agreement 
itself, or of any subsequent breach thereof. No payment of Rent by Tenant or 
acceptance of Rent by Landlord shall operate as a waiver of any breach or 
default by Tenant under this Lease. No payment by Tenant or receipt by 
Landlord of a lesser amount than the monthly installment of Rent herein 
stipulated shall be deemed to be other than a payment on account of the 
earliest unpaid Rent, nor shall any endorsement or statement on any check or 
communication accompanying a check for the payment of Rent be deemed an accord 
and satisfaction, and Landlord may accept such check or payment without 
prejudice to Landlord's right to recover the balance of such Rent or to 
pursue any other remedy provided in this Lease. No re-entry by Landlord, and 
no acceptance by Landlord of keys from Tenant, shall be considered an 
acceptance of a surrender of the Lease.

     22.5  Right of Landlord to Cure Tenant's Default.  If an Event of Default 
shall occur, then Landlord may (but shall not be obligated to) make such 
payment or do such act to cure the Event of Default, and charge the amount of 
the expense thereof, together with interest thereon at the Interest Rate, to 
Tenant. Such payment shall be due and payable upon demand; however, the 
making of such payment or the taking of such action by Landlord shall not be 
deemed to cure the Event of Default or to stop Landlord from the pursuit of 
any remedy to which Landlord would otherwise be entitled. Any such payment 
made by Landlord on Tenant's behalf shall bear interest until paid at the 
Interest Rate.

     22.6  Late Payment.  If Tenant fails to pay any Rent within five (5) days 
after such Rent becomes due and payable, Tenant shall pay to Landlord a late 
charge of five percent (5%) of the amount of such overdue Rent. In addition, 
any such late Rent payment shall bear interest from the date such Rent became 
due and payable to the date of payment thereof by Tenant at the Interest


                                       19





Rate. Such late charge and interest shall be due and payable within two (2) 
days after written demand from Landlord.

     22.7  Landlord Default.  If Landlord shall fail to keep or perform any 
of its obligations under this Lease, then Tenant may (but shall not be 
obligated to do so) upon the continuance of such failure on Landlord's part 
for twenty (20) days after Landlord's receipt of notice from Tenant 
specifying the failure (or, in the case of any such failure which cannot 
with due diligence be cured within twenty (20) days, within such additional 
period, if any, as may be reasonably required by Landlord to cure such 
failure with due diligence), and without waiving or releasing Landlord from 
any obligation, make such payment or perform such obligation and all sums so 
paid by Tenant and all necessary and incidental costs and expenses, including 
reasonable attorney's fees paid to independent legal counsel, incurred by 
Tenant in making such payment or performing such obligation, together with 
interest thereon at the Interest Rate from the date of payment, shall be paid 
by Landlord to Tenant on demand, and if not so paid by Landlord, Tenant shall 
have the right to pursue any legal remedies available to it to collect 
payment, but shall not be entitled to offset such payment against Rent 
thereafter payable under this Lease.

ARTICLE 23: MORTGAGES

     23.1  Subordination.  This Lease is subject and subordinate to all 
ground or underlying leases and to any first Mortgage(s) which may now or 
hereafter affect such ground or underlying leases or the Land or the Building 
and to all renewals, modifications, consolidations, replacements and 
extensions thereof. This subordination shall be self-operative; however, in 
confirmation thereof, Tenant shall execute promptly any instrument that 
Landlord or any first Mortgagee may request confirming such subordination. 
Notwithstanding the foregoing, before any foreclosure sale under a Mortgage, 
the Mortgagee shall have the right to subordinate the Mortgage to this Lease, 
and, in the event of a foreclosure, this Lease may continue in full force and 
effect and Tenant shall attorn to and recognize as its landlord the purchaser 
of Landlord's interest under this Lease. Tenant shall, upon the request of a 
Mortgagee or purchaser at foreclosure, execute, acknowledge and deliver any 
instrument that has for its purpose and effect the subordination of the lien 
of any Mortgage to this Lease or Tenant's attornment to such Purchaser. 
Tenant waives its rights under any statute or law now or hereafter in effect 
which may give Tenant any right to terminate or otherwise adversely affect 
this Lease in the event any foreclosure proceeding ordered in lieu of 
foreclosure is brought under any Mortgage.

     23.2  Mortgagee Protection.  Tenant agrees to give any Mortgagee by 
certified mail, return receipt requested, a copy of any notice of default 
served upon Landlord, provided that before such notice Tenant has been 
notified in writing of the address of 

                                       20




such Mortgagee. Tenant further agrees that if Landlord shall have failed to 
cure such default within the time provided for in this Lease, then Mortgagee 
shall have an additional thirty (30) days within which to cure such default; 
provided, however, that if such default cannot be reasonably cured within 
that time, then such Mortgagee shall have such additional time as may be 
necessary to cure such default so long as Mortgagee has commenced and is 
diligently pursuing the remedies necessary to cure such default (including, 
without limitation, the commencement of foreclosure proceedings, if 
necessary), in which event this Lease shall not be terminated or Rent abated 
while such remedies are being so diligently pursued. In the event of the sale 
of the Land or the Building, by foreclosure or deed in lieu thereof, the 
Mortgagee or purchaser at such sale shall be responsible for the return of 
the Security Deposit only to the extent that such Mortgagee or purchaser 
actually received the Security Deposit.

     23.3  Modification Due to Financing.  If, in connection with obtaining 
construction or permanent financing for the Premises, the Building or the 
Land, any lender (or Mortgagee) shall request reasonable modifications of 
this Lease as a condition to such financing, Tenant shall promptly execute a 
modification of this Lease, provided such modifications do not materially 
increase the financial obligations of Tenant hereunder or materially 
adversely affect the leasehold interest hereby created or Tenant's reasonable 
use and enjoyment of the Premises. Tenant shall, prior to execution and 
throughout the Term, upon request from time to time, provide such financial 
information and documentation about itself to Landlord or Mortgagee as may be 
requested.

ARTICLE 24:  SURRENDER; HOLDING OVER

     24.1  Surrender of the Premises.  Tenant shall peaceably surrender the 
Premises to Landlord on the Expiration Date or earlier termination of this 
Lease, in broom-clean condition and in as good condition as when Tenant took 
possession, including, without limitation, the repair of any damage to the 
Premises caused by the removal of any of Tenant's personal property or trade 
fixtures from the Premises, except for reasonable wear and tear and loss by 
fire or other casualty not caused by Tenant or its Agents. Any of Tenant's 
personal property left on or in the Premises, the Building or the Common Area 
after the Expiration Date or earlier termination of this Lease shall be 
deemed to be abandoned, and, at Landlord's option, title shall pass to 
Landlord under this Lease.

     24.2  Holding Over.  In the event that Tenant shall not immediately 
surrender the Premises to Landlord on the Expiration Date or earlier 
termination of this Lease, Tenant shall be deemed to be a month to month 
tenant (which tenancy may be cancelled upon thirty (30) days advance notice 
by either party) upon all of the terms and provisions of this Lease, except 
that, for the first

 
                                       21




twelve (12) months of any holdover period, annual Base Rent shall increase to 
$27,825.45 and shall be payable in equal monthly installments of $2,318.79, 
and thereafter, the monthly Base Rent during the remainder of any holdover 
period shall be $4,673.58. Notwithstanding the foregoing, if Tenant shall 
hold over for a period in excess of twelve (12) months following the 
Expiration Date or earlier termination of this Lease, and Landlord shall 
desire to regain possession of the Premises, then Landlord may forthwith 
re-enter and take possession of the Premises without process, or by any legal 
process in force in the Commonwealth of Virginia. Tenant shall indemnify 
Landlord against all liabilities and damages sustained by Landlord by reason 
of tenant's retention of possession of the Premises beyond any permitted 
holdover period.

ARTICLE 25:  QUIET ENJOYMENT

     Landlord covenants that if Tenant shall pay Rent and perform all of the 
terms and conditions of this Lease to be quietly performed by Tenant, Tenant 
shall during the Term peaceably and quietly occupy and enjoy possession of 
the Premises without molestation or hindrance by Landlord or any party 
claiming through or under Landlord, subject to the provisions of this Lease 
and any Mortgage to which this Lease is subordinate and easements, conditions 
and restrictions of record affecting the Land.

local laws or regulations applicable to any such Hazardous Material.

     26.3  No Contamination.  Tenant shall not discharge, leak or emit, or 
permit to be discharged, leaked or emitted, any material into the atmosphere, 
ground, sewer system or any body of water, if such material (as reasonably 
determined by the Landlord or any government authority) does or may, pollute 
or contaminate the same, or may adversely affect (a) the health, welfare or 
safety or persons, whether located on the Premises or elsewhere, or (b) the 
condition, use or enjoyment of the Building or any other real or personal 
property.

     26.4  Disclosure.  At the commencement of each Lease Year, Tenant shall 
disclose to Landlord the names and approximate amounts of all Hazardous 
Material which Tenant intends to store, use or 

                                       22



dispose of on the Premises in the coming Lease Year. In addition, at the 
commencement of each Lease Year, beginning with the second Lease Year, Tenant 
shall disclose to Landlord the names and amounts of all Hazardous Materials 
which were actually used, stored or disposed of on the Premises if such 
materials were not previously identified to Landlord at the commencement of 
the previous Lease Year.

     26.5  Definition.  As used herein, the term "Hazardous Material" means 
(a) any "hazardous waste" as defined by the Resource Conservation and 
Recovery Act of 1976, as amended from time to time, and regulations 
promulgated thereunder; (b) any "hazardous substance" as defined by the 
Comprehensive Environmental Response, Compensation and Liability Act of 1980,

     26.6  Indemnity.  Tenant hereby agrees that it shall be fully liable for 
all costs and expenses related to the use, storage and disposal of Hazardous 
Material kept on the Premises by the Tenant, and the Tenant shall give 
immediate notice to the Landlord of any violation or potential violation of 
the provisions of this Article 26. Tenant shall defend, indemnify and hold 
harmless Landlord and its Agents, from and against any claims, demands, 
penalties, fines, liabilities, settlements, damages, costs, or expenses 
(including without limitation, attorney and consultant fees, court costs and 
litigation expenses) of whatever kind or nature, known or unknown, contingent 
or otherwise, arising out of nature, known or unknown, contingent or 
otherwise, arising out of or in any way related to (a) the presence,

and each provision of this Lease shall be valid and be enforced to the full 
extent permitted by law.

Riders, if any, attached hereto) contains and embodies the entire agreement 
of the parties hereto, and no representations, 

                                       25

business in the Commonwealth of Virginia, that the corporation has full power 
and authority to enter into this Lease and that he or she is authorized to 
execute this Lease on behalf of the corporation.

limited to Landlord's equity in the Building as described in Article 1 
hereof. In the event that the original Landlord hereunder, or any successor 
owner of the Building, shall sell or convey the Building, all liabilities and 
obligations on the part of the original Landlord, or such successor owner,

sale, and thereupon all such liabilities and obligations shall be binding on 
the new owner. Tenant agrees to attorn to such new owner. Any successor to 
Landlord's interest shall not be bound by (i) any payment of Base Rent for 
more than one (1) month in advance, except for the payment of the first 

                                       26

consent of such Mortgagee.

obligations contained in this Lease.

     27.16  Force Majeure.  Except for Tenant's obligations to pay Rent under 
this Lease, neither Landlord nor Tenant shall be required to perform any of 
its obligations under this Lease, nor shall such party be liable for loss or 
damage for failure to do so, nor shall the other party thereby be released 
from any of its obligations under this Lease, where such failure by the 
non-performing party arises from or through acts of God, strikes, lockouts, 
labor difficulties, explosions, sabotage, accidents, riots, civil commotions, 
acts of war, results of any warfare or warlike conditions in this or any 
foreign country, fire or casualty, legal requirements, energy shortage or 
other causes beyond the reasonable control of the non-performing party, 
unless such loss or damage results from the will full misconduct or gross 
negligence of the non-prevailing party.


     27.17  Headings.  Captions and headings are for convenience or reference 
only. 

     27.18  Memorandum of Lease.  Tenant shall, at the request of Landlord, 
execute and deliver a memorandum of lease in recordable form. Tenant shall 
not record this Lease or any such memorandum of this Lease. 

     27.19  Landlord's Relocation Option.  At any time during the Term, 
provided at such time Tenant's Premises consist of 5,000 rentable square feet 
or less, Landlord shall have the option to relocate Tenant, at no direct cost 
of Tenant, to space comparable to the Premises elsewhere in the Building, 
provided Landlord gives Tenant three (3) months' written notice. Upon 
relocation, such new space shall be deemed to be the "Premises" hereunder, 
and Tenant's Proportionate Share shall be recalculated by Landlord to equal 
that fraction, the numerator of which is the rentable square footage of the 
Premises and the denominator of which is the rentable square footage of the 
Building (as reasonably determined by Landlord). 

     27.20  Attorney-in-Fact.  If Tenant fails or refuses to execute and 
deliver any instrument or certificate required to be delivered by Tenant 
hereunder (including, without limitations, any instrument or certificate 
required under Article 23 or Section 27.4 hereof) within the time periods 
required herein, then Tenant hereby appoints Landlord as its attorney-in-fact 
with full power and authority to execute and deliver such instrument or 
certificate for and in the name of Tenant.

                                       27



   27.21 Effectiveness. The execution of this Lease by Tenant and delivery of 
the same and of any Trust or Security Deposit to Landlord or its Agent does 
not constitute a reservation of or option for the Premises or an agreement 
to enter into a lease, and this Lease shall become effective only if and when 
Landlord executes and delivers the same to Tenant; provided, however, that 
execution and delivery of this Lease to Landlord or its Agent by Tenant shall 
constitute an irrevocable offer by Tenant to lease the Premises on the terms 
and conditions herein contained, which offer may not be withdrawn or revoked 
for thirty (30) days after such execution and delivery.

   27.22 Tenant's Right to Use Conference Room Facility. Throughout the Term 
of this Lease, during normal business hours (8:00 a.m. - 6:00 p.m., Monday 
through Friday, and 9:00 a.m. - 1:00 p.m. on Saturday), Tenant shall have the 
right to use, on a first-come, first-serve basis along with other tenants in 
the Building, without charge, the conference room facility located on the 
second floor of the Building. If Tenant uses the conference room facility 
other than during normal business hours, Tenant shall be responsible for 
paying to Landlord any costs directly attributable to Tenant's use of such 
facility.

   27.23 Right of First Refusal on Adjacent Space. Provided Tenant is not 
then in default hereunder, Landlord covenants and agrees that if Landlord 
intends to lease the space located in the Building and immediately adjacent 
to the Premises to a  third-party and if Wilder & Gregory elects not to lease 
such space from Landlord, Landlord shall give Tenant written notice of the 
terms and conditions pursuant to which Landlord will agree to lease such 
space to the third party. Tenant shall have ten (10) days following receipt 
of such notice from Landlord in which to notify Landlord of its intent to 
lease such space from Landlord pursuant to the terms and conditions contained 
in Landlord's notice to Tenant. If Tenant fails to notify Landlord of its 
intent to lease such space within such ten (10) day period or thereafter 
fails to enter into a lease for such space within thirty (30) days after the 
date Tenant notifies Landlord of its intent to lease such space, time being 
of the essence in both instances, Tenant shall be deemed to have waived its 
right of first refusal as to such third-party offer, and Landlord shall be 
permitted to enter into a lease for such space with such third-party upon 
substantially the same terms and conditions as contained in Landlord's notice 
to Tenant.

   27.24 Option on Adjacent Space. Provided Tenant is not then in default 
hereunder, Tenant shall have the option, at any time during the Term of this 
Lease, upon thirty (30) days advance written notice to Landlord, to lease the 
space located in the Building and immediately adjacent to the Premises from 
Landlord upon the same terms and conditions as set forth herein, including, 
without limitation, the rental rate set forth herein and applicable to the 
Premises. Notwithstanding the foregoing, if , after


                                      28




receiving Tenant's notice of its intent to exercise its option to lease the 
space located in the Building and immediately adjacent to the Premises, 
Landlord receives notice from Wilder & Gregory that it has elected to lease 
such space from Landlord, Tenant's option to lease such space shall terminate 
and be of no further force and effect.

     During the Term of this Lease, Tenant shall have the right to enter into 
one (1) automobile parking contract for parking in that portion of the 
Parking Facilities consisting of the underground garage located in the 
Building provided by Landlord's Parking Manager (which is currently Virginia 
Parking Service, Inc., and which term shall refer to the person or entity 
which during the Term of the Lease leases the Parking Facilities from 
Landlord and operates the Parking Facilities) at such monthly rates as are 
being customarily charged by the Parking Manager for similar covered parking 
in the City of Richmond, Virginia, for use by Tenant and its employees, and 
subject to the rules and regulations established by Landlord or the Parking 
Manager from time to time. Tenant acknowledges and agrees that the automobile 
parking contract will provide only a license to park one (1) automobile 
within the particular Parking Facility on an unreserved, first-come, 
first-served basis, and that Landlord or Parking Manager shall have the right 
to alter or adjust the size, location, elevation, and/or nature of the 
parking areas within the Parking Facilities, and shall have the right to 
designate certain spaces within the Parking Facilities as "reserved" for 
specific users. In addition to the foregoing, if requested by Tenant, 
Landlord covenants and agrees to assist Tenant in obtaining from the Parking 
Manager additional parking for Tenant and its employees in other Parking 
Facilities within a two (2) block radius of the Building. Such additional 
spaces will be provided by the Parking Manager at such monthly rates as are 
being customarily charged by the Parking Manager for similar parking in the 
City of Richmond, Virginia.

     Landlord reserves the right, at any time and from time to time, to close 
temporarily all or any portions of the Parking Facilities when in Landlord's 
or Parking Manager's reasonable judgment any such closing is necessary or 
desirable (a) to make repairs or changes to effect construction, (b) to 
prevent the acquisition of public rights in such area, (c) to discourage 
unauthorized parking, or (d) to protect or preserve natural persons or 
property. Landlord or Parking Manager may do such other acts in and to the 
Parking Facilities as may be desirable to improve or maintain same. Temporary 
unavailability of parking spaces within the Parking Facilities shall not 
constitute an eviction or give rise to any claim in favor of Tenant for loss 
or damage under this Lease. If at any time during the Term of the Lease, an 
insufficient number of parking spaces in that portion of the Parking 
Facilities consisting of the underground garage located in the Building are 
available for use by all tenants of the Building, Landlord and Parking 
Manager shall have the right to terminate the automobile parking contract and 
provide a replacement parking contract for parking by Tenant within a 
two-block radius of the Building, at such rates as are customarily charged 
for such replacement parking facilities in the City of Richmond, Virginia.



     Tenant agrees that it, any subtenant or licensee and its respective 
officers, employees, contractors and agents will park their automobiles and 
other vehicles only where and as permitted by Landlord or Parking Manager. 
Tenant will, if and when so requested by Landlord or Parking Manager, furnish 
the requesting party with the license numbers and any vehicles of Tenant, any 
subtenant or licensee and its respective officers, employees, contractors and 
agents. Landlord or Parking Manager may remove, at Tenant's expense, any 
vehicles which are parking or abandoned in violation of the rules and 
regulations established by Landlord or Parking Manager from time to time.

Possession. Notwithstanding the foregoing, if Sublessor has not delivered 
Possession to Sublessee within thirty (30) days after the Commencement Date, 
then at any time thereafter and before delivery of Possession, Sublessee may 
give written notice to Sublessor of Sublessee's intention to cancel this 
Sublease. Said notice shall set forth an effective date for such cancellation 
which shall be at least ten (10) days after delivery of said notice to 
Sublessor. If Sublessor delivers Possession to Sublessee on or before such 
effective date, this Sublease shall remain in full force and effect. If 
Sublessor fails to deliver Possession to Sublessee on or before such 
effective date, this Sublease shall be cancelled, in which case all 
consideration previously paid by Sublessee to Sublessor on account of this 
Sublease shall be returned to Sublessee, this Sublease shall thereafter be of 
no further force or effect, and Sublessor shall have no further liability to 
Sublessee on account of such delay or cancellation. If Sublessor permits 
Sublessee to take Possession prior to the commencement of the Term, such 
early Possession shall not advance the Termination Date and shall be subject 
to the provisions of this Sublease, including without limitation the payment 
of rent.

office use and for no other use or purpose.

8. ASSIGNMENT AND SUBLETTING - Sublessee shall not assign the Sublease or 
further sublet all or any part of the Premises without the prior written 
consent of Sublessor (and the consent of Landlord, if such is required under 
the terms of the Master Lease).

9. OTHER PROVISIONS OF SUBLEASE - All applicable terms and conditions of the 
Master Lease are incorporated into and made a part of this Sublease as if 
Sublessor were the Landlord thereunder, and the Sublessee the Tenant 
thereunder, and the Premises the Master Premises. Sublessee, assumes and 
agrees to perform the Tenant's obligations under the Master Lease during the 
Term to the extent that such obligations are applicable to the Premises, 
except that the obligation to pay rent to the Landlord under the Master Lease 
shall be considered performed by Sublessee to the extent and in the amount of 
rent as paid to Sublessor in accordance with Section 6 of this Sublease. 
Sublessee shall not commit or suffer any act or omission that will violate 
any of the provisions of the Master Lease. Sublessor shall exercise due 
diligence in attempting to cause Landlord to perform its obligations under the 
Master Lease for the benefit of the Sublessee. If the Master Lease 
terminates, this Sublease shall terminate and the parties shall be relieved 
of any further liability or obligation under this Sublease, provided however, 
that if the Master Lease terminates as a result of a default or breach by 
Sublessor or sublessee under this Sublease and/or the Master Lease, then the 
defaulting party shall be liable to the non-defaulting party for the damages, 
costs and expenses, including attorney's fees, suffered as a result of such 
termination. Notwithstanding the foregoing, if the Master Lease gives 
Sublessor any right to terminate the Master Lease in the event of the partial 
or total damage, destruction, or condemnation of the Master Premises or the 
building or project of which the Master Premises are a part, the exercise of 
such right by Sublessor shall not constitute a default of breach hereunder. 

10.  ATTORNEY'S FEES - If Sublessor, Sublessee, shall commence an action 
against the other arising out of or in connection with this Sublease, the 
prevailing party shall be entitled to recover its costs of suit and
