square feet on the first floor of the Prime  Premises  ("FIRST FLOOR  PREMISES")
and  approximately  11,751 square feet on the second floor of the Prime Premises

Subtenant on the terms and subject to the conditions hereinafter set forth.

      NOW,  THEREFORE,   for  and  in  consideration  of  the  mutual  covenants
hereinafter contained, the parties hereby agree as follows:

not in default under the Prime Lease; and that, to its best knowledge,  Landlord
is not in default under the Prime Lease.

2.    TERM; AS-IS CONDITION; USE.

     (a) The term (the  "TERM") of this  Sublease  shall  commence on October 1,
1999 (the "COMMENCEMENT DATE") and shall terminate on September 30, 2004, unless
sooner  terminated  or extended  pursuant to the  provisions  of this  Sublease,
provided  however,  that  Subtenant  shall  have  the  right  of  occupancy  and

improve  the  Premises  been  made by  Sublandlord  or any  party on  behalf  of
Sublandlord.

     (c) Subtenant's use of the Premises shall be for general  (non-medical  and
non-governmental)  office use only and only for such other uses as are expressly
permitted pursuant to Section 6.1 of the Prime Lease.

3.   INCORPORATION BY REFERENCE.

      To the extent not inconsistent  with the provisions of this Sublease,  the
terms,  provisions,  covenants,  and  conditions  of the Prime  Lease are hereby
incorporated by reference on the following  basis:  Subtenant hereby assumes all
of the  obligations,  accruing or payable during the Term, of Sublandlord  under

Prime Lease. The term "LANDLORD"  therein shall refer to Sublandlord  hereunder,
its  successors  and  assigns;  and the term  "TENANT"  therein  shall  refer to

Lease.  Subtenant  represents that it has reviewed and accepted all the terms of
the Prime Lease.  Pursuant to Section 7.6 of the Prime Lease,  Subtenant  agrees
that if  Landlord  succeeds  to  Sublandlord's  interest in the Prime Lease then
Landlord at its option may  continue  the terms of this  Sublease  and upon such
occurrence,  Subtenant  agrees to  recognize  Landlord  and be bound to Landlord
under the terms of this  Sublease.  Subtenant  shall execute a written  document
certifying  the term,  the rent and other  relevant  information  concerning the
Premises  or the Prime  Premises  upon five (5) days' prior  written  request of
Landlord or Sublandlord pursuant to Section 25.4 of the Prime Lease.

5.   RENT.

     (a) Subtenant  shall pay to Sublandlord at its office referred to above, or
to such other address as Sublandlord  shall notify Subtenant in writing pursuant
to SECTION 25(H) below, a base rent ("BASE RENT") which shall be due and payable
in  advance  in  monthly  installments  on the first  (1st)  day of each  month,

     (b) Rent shall be paid without deduction or setoff,  and Base Rent shall be
paid  without  notice or demand.  If any Rent shall not be paid on or before the
fifth  (5th)  day after  the due date  thereof,  Subtenant  shall,  in  addition
thereto, pay a late charge of 5% of the overdue installment.

6.   SECURITY DEPOSIT.

     (a) Subtenant herewith deposits the sum of $125,123.25 (the "DEPOSIT") with
Sublandlord  as a  security  deposit  to  assure  the  faithful  performance  by
Subtenant of all of the obligations assumed by it hereunder.  Should part or all
of the  Deposit be applied by  Sublandlord  for the  payment of overdue  Rent or
other obligations of Subtenant  hereunder,  then Subtenant shall, within 15 days
after the written  demand of  Sublandlord,  remit to  Sublandlord  a  sufficient
amount in cash to restore  the  Deposit  to the then  current  sum  taking  into
consideration  any  application  of the  Deposit  to  installments  of Base Rent
pursuant  to  subsection  (b)  below,  and  Subtenant's  failure  to do so shall
constitute  a  default  hereunder.   Upon  the  termination  of  this  Sublease,
Sublandlord shall promptly inspect the Premises and return any unapplied balance
of the Deposit to Subtenant.

     (b) Provided that  Subtenant  shall not then be in default  hereunder,  the
Deposit shall be reduced effective October 1, 2000, to $83,415.50 and the amount
of said  reduction  shall be  applied  by  Sublandlord  as part of the Base Rent
installment which is due October 1, 2000. Provided that Subtenant shall not then
be in default hereunder,  the Deposit shall be further reduced effective October
1, 2001,  to  $41,707.75  and the amount of said  reduction  shall be applied by
Sublandlord as part of the Base Rent installment which is due October 1, 2001.

     (c) Subtenant acknowledges that the security deposit paid by Sublandlord to
Landlord pursuant to the terms of the Prime Lease is the property of Sublandlord
and  that  Subtenant  has no claim or  right  to any  portion  of such  security
deposit.

7.   ESCALATIONS AND ELECTRICAL CHARGES.

     (a) Pursuant to Section 5 of the Prime Lease,  Sublandlord  is obligated to
pay amounts to cover increases in certain taxes imposed upon Landlord. Subtenant
shall pay to Sublandlord  Subtenant's Share of tax increases payable to Landlord
during or with respect to the Term and in accordance with the Prime Lease,  over
and above tax charges of Landlord,  provided however, that the Real Estate Taxes
Base Year (as defined in the Prime  Lease)  shall be deemed to mean the calendar
year 2000 for purposes of this Sublease.


                                       3



     (b) Pursuant to Section 5 of the Prime Lease,  Sublandlord  is obligated to
pay amounts to cover  increases  in operating  expenses of  Landlord.  Subtenant
shall  pay to  Sublandlord  Subtenant's  Share of  operating  expense  increases
imposed by Landlord  during or with respect to the Term and in  accordance  with
the Prime Lease, over and above operating expense charges of Landlord,  provided
however,  that the  Operating  Charges Base Year (as defined in the Prime Lease)
shall be  deemed  to mean  the  calendar  year  2000  for the  purposes  of this
Sublease.

     (c) The minimum  electrical  power  provided to the Premises shall be seven
watts per rentable square foot. In the event that Subtenant's use of electricity
at the  Premises  is in excess of the amount  reasonably  required  for  general
office use, as  reasonably  determined  by  Sublandlord,  then  Subtenant  shall
reimburse Sublandlord for the cost of such excess use.

     (d)  Subtenant  shall pay to  Sublandlord  the cost of any excess  water or
sewage  usage at the  Premises,  as  determined  pursuant to Section 14.3 of the
Prime Lease.

     (e) The amounts required to be paid by Subtenant to Sublandlord  under this
Section shall  constitute  Additional  Rent and shall be paid within thirty (30)
days after  Sublandlord  shall  render a  statement  therefor.  Subtenant  shall
reimburse  Sublandlord for any costs payable to Landlord in connection with this
Sublease. Sublandlord's statement shall be accompanied by copies of any relevant
statements or bills received from Landlord.

8.   SUBLETTING AND ASSIGNMENT.

     (a) Subtenant  shall not,  without the prior written consent of Sublandlord
(a) further sublet all or any part of the Premises;  (b) transfer,  hypothecate,
assign,  convey, or mortgage this Sublease or any interest under it or allow any
lien upon  Subtenant's  interest  hereunder  by operation of law; or (c) suffer,
tolerate,  permit, or allow the use or occupancy of the Premises by anyone other
than Subtenant,  its agents and employees.  Sublandlord  shall not  unreasonably
withhold  or delay its  consent to a further  subletting  of the  Premises or an
assignment  of this  Sublease by  Subtenant.  Sublandlord's  consent to any such
subletting  or  assignment  shall be  conditional  upon and subject to Subtenant
obtaining the written consent of Landlord  thereto when required under the Prime
Lease. No such  transaction  shall release  Subtenant from liability  hereunder.
Notwithstanding the provisions in this Section 8, subject only to the Landlord's
consent if required  under the Prime  Lease,  Subtenant  shall have the right to
sublet or assign the  Premises to a  Permitted  Assignee.  A Permitted  Assignee
shall be an assignment or transfer to any of the following: (a) to a corporation
or  other  business  entity  (herein  sometimes  referred  to  as  a  "successor
corporation")  into or with which Subtenant shall be merged or consolidated,  or
to which  substantially  all of the assets of Subtenant  may be  transferred  or
sold,  provided that (1) such successor  corporation  shall have a net worth and
liquidity at least equal to the net worth and liquidity of Subtenant immediately
prior to such transfer,  (2) the successor  corporation  shall assume in writing
all of the obligations and liabilities of Subtenant under this Sublease, and (3)
the use of the Premises pursuant to such assignment or sublease is in compliance
with the Prime Lease;  or (b) to a corporation or other business  entity (herein
sometimes  referred  to as a  "related  corporation")  that  shall  control,  be
controlled  by or be under  common  control with  Subtenant  or, if unrelated to
Subtenant, that shall purchase all of the assets of Subtenant, provided that (1)
such corporation  shall have a net worth and liquidity at least equal to the net
worth and liquidity of Subtenant  immediately  prior to such  transfer,  (2) the

                                       4



corporation  shall assume in writing all of the  obligations  and liabilities of
Subtenant  under this Sublease and (3) the use of the Premises  pursuant to such
assignment  or sublease is in compliance  with Prime Lease.  In the event of any
such assignment, transfer or subletting,  Subtenant shall remain fully liable as
a primary obligor for the payment of rent and other charges  required  hereunder
and for the performance of obligations to be performed  hereunder.  For purposes
subparagraph  (b) above,  "control" shall be deemed to be the ownership of fifty
percent  (50%) or more of the stock or other voting  interest of the  controlled
corporation  or other  business  entity.  A successor  corporation  described in
subparagraph  (a)  above  or  a  related  or  other  corporation   described  in
subparagraph  (b) above  shall be referred to  sometimes  in this  Sublease as a
"Permitted Assignee."

     (b)  If  any  sublease  or  assignment  (whether  by  operation  of  law or
otherwise, including without limitation an assignment pursuant to the provisions
of the Bankruptcy Code or any other  Insolvency Law) provides that the subtenant
or  assignee  thereunder  is to pay any  amount  in excess of the sum of (a) the
rental and other  charges  due under  this  Sublease,  plus (b) the  reasonable,
out-of-pocket  expenses  (including  (i) the gross rent paid to  Sublandlord  by
Subtenant with respect to the subject  portion of the Premises during any period
in which  alterations are being performed for the assignee or subtenant prior to
its occupancy; (ii) improvement allowances or other economic concessions granted
by Subtenant  to the assignee or  sublessee;  (iii)  alterations  to the subject
portion of the Premises  performed  solely for such  assignee's  or  subtenant's
occupancy and paid for by Subtenant; (iv) costs incurred by Subtenant to buy out
or take over the  previous  lease of the  assignee or  sublessee;  (v) all costs
incurred by  Subtenant  to  advertise  the subject  portion of the  Premises for
assignment or sublease; and (vi) brokerage commissions and/or legal fees paid by
Subtenant in connection with the assignment or sublease; but excluding any costs
attributable  to vacancy  periods  or  "downtime"  other  than those  explicitly
included in clause (i) above) which Subtenant  reasonably incurred in connection
with the procurement of such sublease or assignment, then whether such excess be
in the form of an  increased  monthly  or  annual  rental,  a lump sum  payment,
payment  for the sale,  transfer  or lease of  Subtenant's  fixtures,  leasehold
improvements,  furniture  and other  personal  property (in excess of the market
rates there for), or any other form (and if the subleased or assigned space does
not  constitute  the entire  Premises,  the  existence  of such excess  shall be
determined  on a  pro-rata  basis),  Subtenant  shall pay to  Sublandlord  fifty
percent (50%) of any such excess or other premium  applicable to the sublease or
assignment, which amount shall be paid by Subtenant to Sublandlord as additional
rent as the same is received by Subtenant.

9.   INSURANCE COMPLIANCE.

     (a) Subtenant shall maintain,  at its sole cost and expense,  for the Term,
general public liability insurance (naming  Sublandlord,  Landlord and designees
of Landlord as additional  insureds) against claims for personal injury,  death,
or property damage occurring upon, in, about, or adjacent to the Premises,  such
insurance to afford  protection  with combined  coverage of at least  $4,000,000
with respect to personal injury, death and property damage. Subtenant shall also
maintain,  at its sole  expense,  for the  Term,  any and all  insurance  in the
amounts and form required of  Sublandlord  by and pursuant to the  provisions of
the Prime Lease with respect to the Premises.  All such policies shall be issued
by reputable  insurance  companies approved by Landlord and shall be endorsed to
provide  that they shall not be  modified  or  cancelled  without 30 days' prior
written  notice to Sublandlord  and Landlord.  Prior to the  Commencement  Date,
Subtenant  shall  furnish  said  policies  to  Sublandlord  evidencing  that the


                                       5




required  coverage  is  being   maintained,   together  with  such  evidence  as
Sublandlord shall deem satisfactory of the payment of premiums thereon.

     (b) Notwithstanding  anything to the contrary contained herein,  Sublandord
and Subtenant  each hereby waive any and all right to recover  against the other
(or against their respective  officers,  directors,  trustees,  partners,  joint
venturers,  employees  or agents) for any loss or damage to such  waiving  party
arising from any cause covered by any property damage  insurance  required to be
carried by such party pursuant to this Sublease or, if greater, actually carried
by such party.  Sublandlord  and Subtenant shall secure  appropriate  waivers of
subrogation from their respective insurance carriers;  and each party will, upon
request,   deliver  to  the  other  a  certificate  evidencing  such  waiver  of
subrogation by the insurer.

10.  INDEMNIFICATION.

     (a) Except as explicitly hereinafter set forth, Sublandlord,  its employees
and agents shall not be liable to Subtenant,  any invitee or any other person or
entity for any damage  (including  indirect and consequential  damage),  injury,
loss, or claim  (including  claims for the  interruption of or loss to business)
based on or arising out of any cause whatsoever (except as otherwise provided in
this Section), including without limitation the following: repair to any portion
of the Premises or the building;  interruption in the use of the Premises or any
equipment  therein;  any accident or damage  resulting from any use or operation
(by  Sublandlord,  Subtenant  or any other  person or  entity) to  elevators  or
heating,  cooling,  electrical,  sewerage or plumbing  equipment  or  apparatus;
termination  of this  Sublease  by  reason  of  damage  to the  Premises  or the
building; any fire, robbery, theft, vandalism,  mysterious  disappearance or any
other  casualty;  actions of any other subtenant of the building or of any other
person or entity;  failure or inability to furnish any service specified in this
Sublease;  and leakage in any part of the Premises or the  building  from water,
rain,  ice or snow that may leak into, or flow from, any part of the Premises or
the building,  or from drains, pipes or plumbing fixtures in the Premises or the
building.  If any  condition  exists  which  may  be the  basis  of a  claim  of
constructive  eviction,  then Subtenant  shall give  Sublandlord  written notice
thereof and a  reasonable  opportunity  to correct  such  condition,  and in the
interim Subtenant shall not claim that it has been constructively  evicted or is
entitled to a rent abatement. Any property placed by Subtenant or any invitee in
or about the  Premises or the building  shall be at the sole risk of  Subtenant,
and Sublandlord shall not in any manner be held responsible therefor. Any person
receiving an article  delivered  for  Subtenant  shall be acting as  Subtenant's
agent for such  purpose and not as  Sublandlord's  agent.  For  purposes of this
Section,   the  term   "building"   shall  be  deemed  to   include   the  Land.
Notwithstanding the foregoing provisions of this Section, but subject to Section
9(b),  Sublandlord  shall not be released  from  liability to Subtenant  for any
physical injury to any natural person (including death) or damage to Subtenant's
property  caused  solely and  directly by  Sublandlord's  negligence  or willful
misconduct  to the extent such injury is not covered by insurance (a) carried by
Subtenant  or such  person,  or (b)  required by this  Sublease to be carried by
Subtenant; provided, however, that Sublandlord shall not under any circumstances
be liable for any consequential or indirect damages.

     (b)  Except to the extent  caused by  Sublandlord's  negligence  or willful
misconduct,  and  subject to  Section  9(b)  above,  Subtenant  shall  reimburse
Sublandlord,  its  employees  and agents  for (as  additional  rent),  and shall
indemnify,  defend  upon  request  and hold them  harmless  from and against all


                                       6



costs, damages (but not consequential damages),  claims,  liabilities,  expenses
(including  reasonable  attorneys'  fees),  losses,  penalties  and court  costs
suffered by or claimed against them, to the extent resulting solely and directly
from (i) use and  occupancy  of the  Premises by Subtenant or any invitee or the
business  conducted therein by Subtenant or any invitee,  or (ii) any negligence
or willful  misconduct  by Subtenant  or any  invitee.

     (c)  Except to the  extent  caused by  Subtenant's  negligence  or  willful
misconduct,  and subject to Section  9(b)  above,  Sublandlord  shall  reimburse
Subtenant,  its  employees  and agents  for,  and shall  indemnify,  defend upon
request and hold them  harmless  from and against  all costs,  damages  (but not
consequential  damages),  claims,  liabilities,  expenses (including  reasonable
attorneys'  fees),  losses,  penalties  and court  costs  suffered by or claimed
against them,  to the extent  resulting  solely and directly from  Sublandlord's
negligence or willful misconduct in connection with the management, operation or
repair of the  building.

     (d) If  Subtenant  or any  invitee  is  awarded  a money  judgment  against
Sublandlord, then recourse for satisfaction of such judgment shall be limited to
execution against  Sublandlord's  leasehold interest in the building,  including
Sublandlord's  interest  in all  rents,  income,  profits,  insurance  proceeds,
condemnation  proceeds and sales proceeds arising  therefrom.  No other asset of
Sublandlord,  any partner,  director,  member, officer or trustee of Sublandlord
(each, an "officer") or any other person or entity shall be available to satisfy
or be subject to such judgment,  nor shall any officer or other person or entity
be held to have  personal  liability for  satisfaction  of any claim or judgment
against Sublandlord or any officer.

11.  CASUALTY.

      If the  Prime  Premises  or the  Premises  are  damaged  by fire or  other
casualty,  and Landlord or Sublandlord shall, pursuant to the terms of the Prime
Lease,  elect to  terminate  the Prime  Lease,  this  Sublease  shall  cease and
terminate  on the date of  termination  of the Prime  Lease,  and Rent  shall be
apportioned from the time of the damage.  Otherwise,  this Sublease shall remain
in full force and effect,  subject to the terms of the Prime Lease.  Sublandlord
shall  have no  obligation  hereunder  to repair any  portion  of the  Premises,
whether or not this Sublease  shall be terminated.  If Sublandlord  receives any
rent abatement under the Prime Lease, then Subtenant shall  accordingly  receive
rent  abatement.  In the event  that the  Premises  are  damaged  or  destroyed,
Subtenant  shall have the right to terminate  this  Sublease if the  Restoration
Estimate,  as defined in the Prime Lease and as delivered to Sublandlord,  has a
repair and  restoration  date that is more than two hundred  seventy  (270) days
from the date of the damage or destruction.

12.  RIGHTS OF LANDLORD.

     (a)  Subtenant  acknowledges  any and all rights  specifically  reserved by
Landlord  under the Prime  Lease and  Subtenant  further  acknowledges  that its
possession and use of the Premises shall at all times be subject to such rights.
Subtenant  hereby  releases  Sublandlord  from all liability in connection  with
Landlord's  exercise of such rights,  except for Sublandlord's  gross negligence
and willful misconduct.

     (b) After reasonable notice, if Subtenant fails to perform any act required
of it hereunder  or under the Prime Lease,  Sublandlord  may perform  same,  and


                                       7



Subtenant  shall pay the cost thereof as Additional Rent within thirty (30) days
after receiving Sublandlord's statement therefor.

13.  DEFAULT BY LANDLORD.

      Sublandlord  shall not be liable to Subtenant  for  Landlord's  failure to
perform  any  of  Landlord's  obligations  under  the  Prime  Lease,  nor  shall
Sublandlord have any obligation to perform same or to bring legal proceedings or
take any other  action  against  Landlord to assure  performance  of  Landlord's
obligations under the Prime Lease. Except as otherwise provided herein, whenever
Sublandlord  shall have the right to enforce any rights against  Landlord or any
other party  under the Prime Lease  because of the default or breach of Landlord
or such other party with respect to the  Premises,  and if,  within a reasonable
period after Subtenant's request, Sublandlord fails to enforce such rights, then
Subtenant  shall have the right,  in the name of Subtenant or, if necessary,  in
the name of Sublandlord,  to enforce any such rights of Sublandlord with respect
to the Premises. Such enforcement shall be at the sole expense of Subtenant, and
Subtenant shall indemnify Sublandlord against all costs and expenses,  including
but not  limited  to  reasonable  attorneys'  fees,  which  may be  incurred  by
Sublandlord in connection with any claim, action, or proceeding so undertaken by
Subtenant. Any amount of recovery obtained by Subtenant shall be the property of
Subtenant.

14.  BROKER.

      The  parties  acknowledge  that this  Sublease  was  procured  through the
efforts of Trammell Crow Real Estate Services (Sublandlord's Broker) and Hinders
Realty, Inc.  (Subtenant's  Broker),  and Sublandlord's  Broker shall compensate
Subtenant's  Broker pursuant to separate  agreements.  Subtenant and Sublandlord
represent  and warrant that they dealt with no other broker in  connection  with
this  Sublease and shall hold each other  harmless  from any  liability or loss,
including  reasonable  attorneys' fees, to any broker or salesman (other than as
aforesaid)  claiming a commission as a result of having an interested  Subtenant
in the Premises.

15.  TAXES.

      Subtenant  shall  pay  any  taxes  or  fees  imposed  by any  governmental
authority upon or as the result of this Sublease or the transfer of any property
or interests in property  hereunder,  except that Subtenant  shall not be liable
for any federal,  state, or municipal  income tax imposed upon  Sublandlord as a
result of this Sublease or any profits derived hereunder.

16.  REMEDIES.

      The  taking of any action by  Subtenant,  the  occurrence  of any event in
regard to Subtenant, or the failure to act by Subtenant which would be a default
under the Prime  Lease if taken by  Sublandlord  or if  occurring  or failing to
occur in regard to  Sublandlord,  shall entitle  Sublandlord  to take all action
with regard to Subtenant under this Sublease which Landlord is permitted to take
against  Sublandlord  under  the  terms of the  Prime  Lease.  Subtenant  hereby
indemnifies  and holds  Sublandlord  harmless  from and against all loss,  cost,
injury,  liability,  or expense (including  reasonable attorneys' fees and court
costs) caused by or arising out of Subtenant's default,  breach, or violation of
the terms of this Sublease.

performed in  accordance  with the terms of the Prime Lease,  including  without
limitation, Section 9 thereof, and all of Subtenant's work shall be completed in
a good,  workmanlike and first-class manner.  Sublandlord shall assist Subtenant
in securing  Landlord's  consent  for any such work.  Provided  Subtenant  gives
Landlord prior written  notice,  Subtenant may perform in the Premises,  without
obtaining Landlord's prior written consent, minor, non-structural alterations of
a decorative  nature which are reasonably  comparable to the colors and finishes
in the  Premises  as of the date of this  Sublease  and  which do not  require a

that all costs  associated with this provision shall be paid by Subtenant.  Such
signage shall be of  comparable  size and location as  Sublandlord's  subject to
Subtenant's approval,  Landlord's approval and applicable municipal regulations.

     (d) Subtenant  and  Sublandlord  shall  cooperate so that both parties have
access to and efficient use of all telephone, data, network, fiber optic and T-1

each secure  their own systems at their  respective  locations  and at their own
cost.

19.  SERVICES AND OTHER PRIVILEGES.

     (a) Sublandlord shall provide or cause to be provided  janitorial  services
for the Premises on a daily basis but not on weekends and federal holidays.

     (b) Subtenant  shall have the right to park 95 vehicles,  of which four (4)

                                       9



accommodation  of  Subtenant,  and  Sublandlord  assumes  no  responsibility  or
liability  of any kind  whatsoever  from  whatever  cause  with  respect  to the
automobile parking areas,  including  adjoining streets,  sidewalks,  driveways,
property  and  passageways,  or the use  thereof  by  Subtenant  or  Subtenant's

the sole use of said reserved  parking spaces by Subtenant.

     (c) Subtenant shall have non-exclusive access to and use of the first floor

supplied to  Subtenant's  employees.

     (d)  Subtenant  may  utilize  Sublandlord's  training  rooms for client and
employee training at no cost to Subtenant,  provided  however,  that such use is
subject to the availability of said rooms at Sublandlord's sole discretion. Upon
reasonable  notice to  Subtenant,  Sublandlord  reserves the right to modify the
Premises to remove all or part of said  training  rooms.

     (e) Subject to Section 1.19 of the Prime Lease, Subtenant shall have access
to the Premises twenty four hours a day, seven days a week, 365 days a year.

     (f)  Subtenant  shall have the right to utilize  certain  furniture  at the

Landlord's  consent pursuant to Section 19.7 of the Prime Lease.

     (g)  Sublandlord  does not warrant  that any of the  services or  utilities
referred to in this Sublease,  or any other services or utilities which Landlord
may supply, will be free from interruption,  and Subtenant acknowledges that any
one or more such  services  may be  suspended  by reason of  accident,  repairs,
inspections,  alterations,  improvements or other reasons. Any such interruption
or  discontinuance  of service shall not be deemed an eviction or disturbance of
Subtenant's use and possession of the Premises,  or any part thereof, nor render
Sublandlord  liable  to  Subtenant  for  damages  by  abatement  of the  Rent or
otherwise,  nor relieve  Subtenant from  performance of Subtenant's  obligations
under this Sublease.

20.  RIGHT TO RENEW.

     (a)  Subtenant  shall have one  option to extend the Term of this  Sublease
until  the last day of the  term of the  Prime  Lease,  which  is  scheduled  to
terminate  on April 30, 2009 (the  "Renewal  Option").  The terms of the Renewal
Option  shall be in  accordance  with all of the  terms and  conditions  of this
Sublease, except that Base Rent shall be based on the then current market rental
value.

     (b) The Renewal Option may only be exercised by Subtenant by written notice
of exercise  given by Subtenant to Sublandlord  and received by Sublandlord  not
earlier  than March 30,  2004,  and not later than May 30,  2004.  Failure to so
exercise within such period shall render any subsequent  attempted exercise void
and of no  effect,  any  principles  of law  to  the  contrary  notwithstanding.
Subtenant shall have no right to exercise the Renewal Option,  and any attempted
exercise  shall  be void and of no  effect,  if:  (i) the  named  Subtenant  has


                                       10



assigned this Lease or has at any time  subleased,  in the aggregate,  more than
50% of the Premises;  or (ii) Subtenant  shall be in default  hereunder and such
default shall not have been cured at the time of the  attempted  exercise or, if
such default occurs after Subtenant's  attempted  exercise of the option, at the
time of the proposed  commencement  of the extension Term.

     (c) In the event that the parties  have not agreed upon the current  market
rental  value  of  the  Premises  prior  to  the  date  two  months  before  the
commencement   of  the  extension  Term,  such  value  shall  be  determined  by
arbitration  in the City of  Washington,  D.C.,  before a single  arbitrator  as
follows:

          (i)  Sublandlord  and  Subtenant  shall have ten days within  which to
select one mutually  agreeable  arbitrator  who shall have a minimum of ten (10)
years'  experience in Northern  Virginia  commercial real estate. If Sublandlord
and Subtenant fail to agree on one arbitrator within the ten day period,  either
party may  promptly  request  the  president  of the local  Board of Realtors to
appoint an arbitrator for the matter,  and said  president's  selection shall be
binding upon Sublandlord and Subtenant.

          (ii) Sublandlord and Subtenant shall each submit to the arbitrator, in
writing,  a good faith  determination  of the current market rental value of the
Premises.

          (iii) The  appraiser  selected  must choose  either  Sublandlord's  or
Subtenant's good faith determination of the rental value of the Premises and the
appraiser's choice shall be final and binding upon the parties. From the date of
appointment, the arbitrator shall have 30 days within which to render a decision
as to the rental value of the Premises.  Judgment upon the award rendered by the
arbitrator  shall be binding upon the parties and may be entered in any court of
competent  jurisdiction.  The  arbitrator  shall  determine the liability of the
parties for the costs of the arbitration and may allocate counsel fees,  witness
fees and other costs between the parties.

21.  RIGHT OF FIRST REFUSAL.

     (a) If, at any time  during  the  Initial  Term any  rentable  space in the
portion  of the  Prime  Premises  occupied  by  Sublandlord  either is vacant or
becomes  available and Sublandlord  does not desire to occupy such space itself,
then  before  entering  into a lease  for such  space  with  another  Subtenant,
provided Subtenant is not in default hereunder, Sublandlord shall send Subtenant
a notice  describing the premises (the "INTENT TO LEASE Notice") and shall offer
to lease such space to Subtenant upon the same terms set forth in this Sublease.
Provided  that  Subtenant  is not in  default  hereunder,  Subtenant  shall have
fifteen (15) business days after receipt of the Intent to Lease Notice to accept
such offer by notice to Sublandlord,  time being of the essence. After accepting
such offer,  Subtenant  shall  promptly,  at  Sublandlord's  option,  execute an
amendment to this Sublease prepared by Sublandlord.

     (b) If  Subtenant  does not accept  such  offer  within  the  fifteen  (15)
business day period provided above, then Sublandlord shall be free to lease such
space to any party upon any terms or  conditions  Sublandlord  shall  determine,
from time to time during the Term,  without any further  obligation to Subtenant
under  this  Sublease  so long as such terms of rent are not less  favorable  to
Sublandlord.  If Subtenant  does not accept such offer within such period,  then


                                       11



Subtenant shall, within ten days after demand by Sublandlord, confirm in writing
to Sublandlord  that Subtenant has declined to exercise or has waived its rights
under this Section.

     (c)  Sublandlord  shall  have no  obligation  to make such  offer,  and any
attempted  acceptance shall be void and of no effect, if (i) the named Subtenant
has assigned  this Lease to an entity  other than a Permitted  Assignee or shall
have subleased, in the aggregate, 50% or more of the Premises to an entity other
than a Permitted  Assignee at any time prior to the Intent to Lease  Notice;  or
(ii)  Subtenant  or any  Permitted  Assignee  shall have  committed  an event of
default  hereunder  which  has  not  been  cured  at the  time  of the  proposed
commencement of the lease of such additional  space.

     (d) This Section shall not preclude preliminary  discussions,  whether oral
or in writing,  between  Sublandlord  and any prospective  Subtenant  concerning
terms and conditions for the leasing of any space in the Prime Premises.

22.  EXPANSION OF SPACE.

     (a) At any time prior to the third  anniversary of the  Commencement  Date,
Subtenant shall have the right to sublease  approximately  five thousand (5,000)
square  feet of  additional  space which is  immediately  adjacent to the Second
Floor Premises and currently  occupied by Sublandlord's  training room and which
is shown on EXHIBIT C attached  hereto  (the  "EXPANSION  SPACE")  upon the same
terms of this Sublease and upon not more than nine (9) months' and not less than
six (6) months' prior written notice to Sublandlord  (the  "EXPANSION  NOTICE").
Upon  receipt of the  Expansion  Notice,  Sublandlord  shall send  Subtenant  an
amendment to this Sublease  incorporating  the Expansion Space. The execution of
an amendment for the Expansion  Space shall give Landlord the right to recapture
the  Premises  pursuant  to  Section  7.4 of the Prime  Lease.  Sublandlord  and
Subtenant  shall  proceed  with said  amendment  pursuant  to SECTION 23 of this
Sublease.

     (b) Sublandlord  shall have no obligation to lease the Expansion  Space, if
(i) the named  Subtenant  has  assigned  this  Lease to an entity  other  than a
Permitted Assignee or shall have subleased, in the aggregate, 50% or more of the
Premises to an entity  other than a Permitted  Assignee at any time prior to the
Expansion  Proposal;  or (ii)  Subtenant or any  Permitted  Assignee  shall have
committed an event of default  hereunder which has not been cured at the time of
the  proposed  commencement  of the  lease of such  additional  space.

23.  RIGHT TO RECAPTURE.

      Both parties  acknowledge that pursuant to Section 7.4 of the Prime Lease,
Landlord has the right to recapture the Premises if  Sublandlord  subleases more
than 50% of the Prime  Premises.  The  parties  acknowledge  that if  Subtenant,
pursuant  to  SECTION  21  or  SECTION  22  of  this  Sublease,  subleases  from
Sublandlord  additional space, then Landlord may exercise said recapture rights.
In such event,  Sublandlord  shall  endeavor  to  negotiate  with and  otherwise
encourage  Landlord  to use  Landlord's  best  efforts to  negotiate  first with
Subtenant prior to leasing the Premises to any other tenant.


                                       12



24.  SURRENDER AND HOLDOVER.

     (a) Upon any  termination  of this  Sublease,  by expiration of the Term or
otherwise:

          (i)  Subtenant  shall  immediately  vacate the Premises and  surrender
possession  thereof to  Sublandlord  in the condition  required  under the Prime
Lease as of the expiration date of the Prime Lease;

          (ii)  Subtenant  shall  surrender  the Premises  free and clear of all
liens and encumbrances; and

          (iii)  Sublandlord  shall have full authority and license to enter the
Premises and take possession of same.

     (b) Subtenant shall pay to Sublandlord 150% of the Base Rent hereunder plus
all other costs for each month or portion  thereof that  Subtenant  shall retain
possession  of the Premises or any part thereof  after the  termination  of this
Sublease,  whether by lapse of time or otherwise, and shall also pay all damages
sustained  by  Sublandlord   to  Landlord  or  otherwise  on  account   thereof.
Furthermore,  Subtenant  shall be subject to eviction  proceedings and any other
remedy or right accorded to Sublandlord in law or at equity. Any holding over by
Subtenant  upon  termination  of  this  Sublease  shall  not be  evidence  of an
extension or renewal of the Term hereof,  nor shall  acceptance of Rent or other
payments by Sublandlord  from Subtenant be evidence of the same, but shall be on
a month to month basis, terminable by either party on 30 days' notice.

25.  MISCELLANEOUS.

     (a) Each  provision  of this  Sublease  shall  extend to and shall bind and
inure to the benefit of Sublandlord and Subtenant and their respective permitted
successors and assigns.

     (b) Subtenant  acknowledges  that this Sublease is subordinate to the Prime
Lease.  In the event of any conflict  between the terms and  conditions  of this
Sublease  and the  terms  and  conditions  of the  Prime  Lease,  the  terms and
conditions of this Sublease shall  control.

     (c) In the  event  that any  provision  of this  Sublease  is  deemed to be
invalid or  unenforceable  for any reason (except for Section 2 of this Sublease
as it pertains to the right of  possession  and use of the  Premises)  then this
Sublease shall be construed as not containing such provision, and the invalidity
or  unenforceability  thereof  shall  not  render  any other  provision  of this
Sublease  invalid or  unenforceable.

     (d) Any  provision  of this  Sublease  or the Prime  Lease  which  requires
Sublandlord  not to  unreasonably  withhold its consent shall never be the basis
for an award of loss of  business  damages  or give rise to a right of setoff to
Subtenant,  but  may  be  the  basis  for a  declaratory  judgment  or  specific
injunction with respect to the matter in question.

     (e) Whenever  Subtenant  must obtain the consent of  Landlord,  Sublandlord
shall  cooperate  with  Subtenant  (at  Subtenant's  sole cost and  expense)  in
obtaining  Landlord's  consent.  Sublandlord shall promptly forward to Subtenant
copies  of  all  notices,  requests,  demands  and  communications  received  by


                                       13



Sublandlord  from  Landlord  (or its agent)  with  respect to the  Premises.  If
Subtenant shall not give timely directions to Sublandlord,  Sublandlord may give
such notice to Landlord as Sublandlord  desires,  or no notice or direction with
respect to the matter in question.  If  Sublandlord's  consent is required under
this  Sublease  or the Prime  Lease  and  Subtenant  has  requested  in  writing
Sublandlord's  consent,  Sublandlord's  failure to respond to  Subtenant  within
thirty (30) days from the date of Subtenant's  request shall be deemed to be the
consent of Sublandlord.  Landlord's  failure to respond to a request for consent
shall not be deemed to be the consent of Landlord.

     (f) Subtenant shall receive notice of any default by Sublandlord  under the
Prime Lease and shall have the right to cure said default if  Sublandlord  fails
to do so in a  reasonable  time.  Any  costs  incurred  by  Subtenant  to remedy
Sublandlord's  default  may be setoff  against  the Rent.

     (g) Subtenant shall indemnify and hold Sublandlord  harmless from the costs
of any special  services  which  Subtenant may order directly from Landlord with
respect to the Premises.

     (h) All notices shall be in writing,  mailed certified mail, return receipt
requested,  postage  prepaid,  or sent by recognized  overnight  courier such as
United Parcel  Service,  addressed to the parties at the  addresses  first above
written,  except that after the Commencement Date,  Subtenant's address shall be
the  Premises.  Either  party may, by such  notice,  change the address to which
notices are to be sent. A copy of any notice to Sublandlord alleging a breach by
it of its obligations  hereunder shall be  simultaneously  sent to Kelley Drye &
Warren LLP, 281 Tresser  Boulevard,  Stamford,  Connecticut  06901, Attn: Jay R.
Schifferli,  Esq. . A copy of any notice to Subtenant alleging a breach by it of
its obligations  hereunder shall be simultaneously  sent to Whiteford,  Taylor &
Preston L.L.P.,  1025 Connecticut Avenue,  N.W.,  Washington,  D.C.  20036-5405,
Attn:  Glenn T.  Bonard,  Esq.

     (i) Each provision of this Sublease has been mutually negotiated,  prepared
and  drafted;  each  party  has been  represented  by  legal  counsel;  and,  in
connection with the construction of any provision  hereof or deletion  herefrom,
no consideration  shall be given to the issue of which party actually  prepared,
drafted,  requested or negotiated  any such  provision or deletion.

     (j)  Neither  party  shall  record  this  Sublease  or the Prime Lease or a
memorandum of this Sublease or the Prime Lease, pursuant to Section 25.16 of the
Prime Lease.

     (k)  Subtenant  shall not cause or permit  any  Hazardous  Materials  to be
generated,  used,  released,  stored or  disposed  of in or about  the  Premises
provided  that  Subtenant  may use and store  reasonable  quantities of standard
cleaning  materials  as may be  reasonably  necessary  for  Subtenant to conduct
normal general  office use operations in the Premises and reasonable  quantities
of Hazardous Materials commonly used in light electronic assembly and testing of
computers in connection  with the operations in the Premises of which  Subtenant
has provided  Landlord and Sublandlord  prior written notice,  provided the same
are  handled,  stored  and  disposed  of in  accordance  with all  Laws.  At the
expiration or earlier  termination of this Sublease,  Subtenant  shall surrender
the  Premises  to  Sublandlord  free of  Hazardous  Materials  generated,  used,
released,  stored,  or disposed of by Subtenant or its invitees not in violation


                                       14



of any  Environmental  Laws as a result of the acts or omissions of Subtenant or
its  invitees.  "Hazardous  Materials"  means  (a)  asbestos  and  any  asbestos
containing  material  and any  substance  that is then  defined or listed in, or
otherwise  classified pursuant to, any Environmental Law or any other applicable
Law  as  a  "hazardous  substance,"  "hazardous  material,"  "hazardous  waste,"
"infectious   waste,"  "toxic   substance,"   "toxic  pollutant"  or  any  other
formulation  intended  to define,  list,  or  classify  substances  by reason of
deleterious   properties   such  as   ignitability,   corrosivity,   reactivity,
carcinogenicity,  toxicity,  reproductive  toxicity, or Toxicity  Characteristic
Leaching  Procedure  (TCLP)  toxicity,  (b) any petroleum  and drilling  fluids,
produced waters,  and other wastes associated with the exploration,  development
or production of crude oil,  natural gas, or geothermal  resources,  and (c) any
petroleum product,  polychlorinated  biphenyls,  urea  formaldehyde,  radon gas,
radioactive  material  (including  any source,  special  nuclear,  or by-product
material),  medical waste,  chlorofluorocarbon,  lead or lead-based product, and
any other  substance  whose presence could be detrimental or hazardous to health
or the environment. "Environmental Law" means any present and future Law and any
amendments (whether common law, statute, rule, order,  regulation or otherwise),
permits  and  other  requirements  or  guidelines  of  governmental  authorities
applicable to the and relating to the environment and  environmental  conditions
or to any Hazardous Material (including,  without limitation,  CERCLA, 42 U.S.C.
ss. 9601 et seq., the Resource  Conservation and Recovery Act of 1976, 42 U.S.C.
ss. 6901 et seq., the Hazardous Materials Transportation Act, 49 U.S.C. ss. 1801
et seq., the Federal Water  Pollution  Control Act, 33 U.S.C.  ss. 1251 et seq.,
the Clean Air Act, 33 U.S.C.  ss.7401 et seq., the Toxic Substances Control Act,
15 U.S.C.  ss. 2601 et seq., the Safe Drinking  Water Act, 42 U.S.C.  ss. 300fet
seq., the Emergency Planning and Community Right-To-Know Act, 42 U.S.C. ss. 1101
et seq., the Occupational  Safety and Health Act, 29 U.S.C. ss. 651 et seq., and
any so-called  "Super Fund" or "Super Lien" law, any Law requiring the filing of
reports  and  notices  relating  to  hazardous  substances,  environmental  laws
administered by the Environmental  Protection  Agency, and any similar state and
local Laws, all amendments thereto and all regulations,  orders,  decisions, and
decrees now or hereafter  promulgated  thereunder  concerning  the  environment,
industrial  hygiene  or  public  health  or  safety).

          (i) Notwithstanding any termination of this Sublease,  Subtenant shall
indemnify  and hold  Sublandlord,  its  employees  and agents  harmless from and
against any damage, injury, loss, liability, charge, demand or claim based on or
arising  out of the  presence  or removal  of, or  failure to remove,  Hazardous
Materials generated,  used, released,  stored or disposed of by Subtenant or any
invitee in or about the Premises,  whether before or after Sublease Commencement
Date.  In  addition,  Subtenant  shall  give  Sublandlord  immediate  verbal and
follow-up  written  notice of any actual or  threatened  Environmental  Default,
which  Environmental  Default  Subtenant  shall  cure  in  accordance  with  all
Environmental  Laws and only after  Subtenant  has  obtained  Sublandlord's  and
Landlord's  prior written  consent,  which shall not be  unreasonably  withheld,
conditioned,  or delayed. An "Environmental  Default" means any of the following
by Subtenant or any invitee: a violation of any applicable  Environmental Law; a
release, spill or discharge of a Hazardous Material on or from the Premises, the
land or the  building  in  violation  of any  applicable  Environmental  Law; an
environmental  condition.  Upon any  Environmental  Default,  in addition to all
other rights  available to Sublandlord  under the Sublease and to Landlord under
the Prime Lease,  at law or in equity,  Sublandlord  and Landlord shall have the
right but not the obligation to immediately enter the Premises, to supervise and
approve any actions  taken by  Subtenant to address the  Environmental  Default,
and,  if  Subtenant  fails to  immediately  address  same to  Sublandlord's  and
Landlord's  reasonable  satisfaction,  to  perform, at Subtenant's sole cost and


                                       15



expense, any lawful action necessary to address same. If any governmental agency
shall require testing to ascertain  whether an Environmental  Default is pending
or  threatened,  then  Subtenant  shall pay the  reasonable  costs  therefor  as
additional  rent.  If any lender shall require  testing to ascertain  whether an
Environmental  Default is pending or  threatened,  and such  testing  reveals an
Environmental Default, then Subtenant shall pay the reasonable costs therefor as
additional  rent.  Promptly upon request,  Subtenant  shall execute from time to
time affidavits,  representations and similar documents  concerning  Subtenant's
best knowledge and belief regarding the presence of Hazardous Materials at or in
the building, the Land or the Premises.

          (ii)  As of the  date of  Sublandlord's  execution  of this  Sublease,
Sublandlord  represents  and  warrants  that it has no actual  knowledge  of the
violation of any  Environmental Law applicable to the building or the land which
remains  uncured,  and that,  to its  knowledge  based solely on the  Landlord's
representation in Section 6.5 of the Prime Lease relying on that certain Phase I
Environmental  Report  prepared  by Dames & Moore,  Inc.,  dated June 10,  1997,
except as otherwise set forth therein no Hazardous  Materials are present in the
building or the land that are in  violation of any  Environmental  Law as of the
date of Sublandlord's  execution of this Sublease.  Unless caused by Subtenant's
or an invitee's  negligence or willful  misconduct,  and subject to Section 9(b)
above,  Sublandlord  shall  indemnify,  defend upon  request  and hold  harmless
Subtenant,  its employees and agents from and against any and all costs, damages
(but  not  consequential  damages),  claims,  liabilities,  expenses  (including
reasonable  attorneys'  fees) and court  costs  suffered  by or claimed  against
Subtenant as the sole and direct result of the generation, storage or release of
Hazardous   Materials  by   Sublandlord,   its  invitees,   agents,   employees,
contractors,  family members of employees,  licensees,  or guests (except to the
extent  the same also  constitute  Subtenant  or its  invitees)  in or about the
building,   to  the  extent  such  generation,   storage,  or  release  violates
Environmental Laws.  Subtenant shall notify Sublandlord  promptly in the event a
claim is made against Subtenant as aforesaid.

26.  LANDLORD'S APPROVAL.

      Upon execution of this Sublease, Sublandlord shall submit this Sublease to
Landlord for  Landlord's  approval.  In the event that Landlord fails to approve
this  Sublease  within  fifteen (15)  business  days of the date hereof,  either
party,  upon  notice  to the  other  within  five (5)  business  days  after the
