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

         1.                PREMISES, RENT AND TERM. (a) Sub-Sublessor hereby
                  leases to Sub-Sublessee approximately 4,258 rentable square
                  feet, more or less, of space on the 3rd floor of the Building,
                  shown on Exhibit "A" (the "Sublease Premises") commencing

                  March 31, 2004 (the "Term").

                  (b) The base rent for such Sublease Premises shall be
                  $10,112.75 calendar month during the Term. The base rent shall
                  be paid beginning August 1, 2001 (the "Rent Commencement
                  Date").

                  (c) Sub-Sublessee shall pay the base rent and Additional Rent
                  as defined in Section 3 below (collectively the "Rent")
                  provided for hereunder in advance on the first day of every
                  month during the Term. If Rent is not received within ten
                  (10) days after the due date, Sub-Sublessee agrees to pay a
                  late payment to Sub-Sublessor equal to 10% of the installment
                  of the Rent.


                  (d) Notwithstanding anything to the contrary contained
                  herein, Sub-Sublessee shall pay the Rent directly to the
                  Sub-Sublessor, Sublessor, or Prime Landlord, as
                  Sublessor shall direct.

                  (e) Sub-Sublessee shall have the use of Sub-Sublessor's
                  parking under the Sublease.

         2.                ASSIGNMENT.  Sub-Sublessee shall not have the
                  right to assign this Sub-Sublease or further sublet the
                  Sublease Premises, in whole or in part, nor shall Sub-
                  Sublessee permit Sub-Sublessee's interest in this Sub-
                  Sublease to be vested in any third-party by operation
                  of law or otherwise, without the prior written approval
                  from Sub-Sublessor, Sublessor, and the Prime Landlord.

         3.                OTHER CHARGES.  Sub-Sublessee shall be liable for
                  100% of electricity charges relating to the Sublease Premises.
                  Sub-Sublessee shall pay, on the first of every month during
                  the Term beginning August 1, 2001, one-twelfth (1/12) of
                  annual estimated electricity charges of $1.50 a square foot of
                  the Sublease Premises. At the end of each calendar year during
                  the Term hereof, Sub-Sublessor shall prorate the actual
                  electricity charges allocable to the Sublease Premises based
                  upon the electricity charges presented to Sub-Sublessor by
                  Sublessor, or by the Prime Landlord. In the event the
                  estimated electricity charges paid by Sub-Sublessee do not
                  equal or exceed the prorated actual electricity charges,
                  Sub-Sublessee shall immediately pay the difference to
                  Sub-Sublessor. In the event Sub-Sublessee is entitled to a
                  credit, it shall be applied to the next installment of Rent.
                  If Sub-Sublessee shall procure any additional services from
                  the Building, such as after-hour HVAC, Sub-Sublessee shall
                  pay for same at the rates charged therefore by the Prime
                  Landlord and shall make such payment to the Sub-Sublessor,
                  Sublessor, or Prime Landlord, as Sublessor shall direct. Any
                  Rent or other sums payable by Sub-Sublessee under this
                  Paragraph 3 shall be Additional Rent and collectible by
                  Sub-Sublessor as such. If Sub-Sublessor shall receive any
                  refund from Prime Landlord, or Sublessor, Sub-Sublessee shall
                  be entitled to the return of so much thereof as shall be
                  attributable to prior payments by Sub-Sublessee.

         4.                SUBORDINATE TO PRIME LEASE AND SUBLEASE.  This Sub-
                  Sublease is subject and subordinate in all instances and under
                  all circumstances to the Prime Lease and the Sublease. In case
                  of any breach hereof by Sub-Sublessee, Sub-Sublessor shall
                  have all the rights against Sub-Sublessee as would be
                  available to Prime Landlord against "Tenant" under the Prime
                  Lease.

         5.                USE. Sub-Sublessee shall use the Sublease Premises in
                  accordance with and subject to the Prime Lease, and in a
                  manner which does not interfere with Tenant or Sub-Sublessor,
                  or create any disturbance or nuisance to any other party.




         6.                SERVICES. Not withstanding anything to the contrary
                  contained herein, the only services or rights to which Sub-
                  Sublessee is entitled hereunder are those to which
                  Sub-Sublessor is entitled to as a Sublessee under the Sublease
                  and that for all such services and rights Sub-Sublessee will
                  look to Prime Landlord under the Prime Lease. In the event
                  Sub-Sublessor is in default as Sublessee under the Sublease,
                  Sub-Sublessee shall have the right to cure Sub-Sublessor's
                  default and pay any Rent payable hereunder directly to the
                  Prime Landlord or Sublessor.

         7.                NO ACTS; INDEMNITY. (a) Sub-Sublessee shall neither
                  do nor permit anything to be done which would cause the Prime
                  Lease or Sublease to be terminated or forfeited or any claims
                  to accrue to the benefit of the Prime Landlord by reason of
                  any right of termination or forfeiture reserved or vested
                  in Prime Landlord under the Prime Lease, or any rights to
                  damages accruing to or for the benefit of Prime Landlord
                  under the Prime Lease.

                  (b) Sub-Sublessee hereby indemnifies and holds Sub-Sublessor
                  and Sublessor harmless from and against all loss, cost, damage
                  or expense, including, but not limited to, attorneys' fees and
                  court costs, incurred by Sub-Sublessor or Sublessor by reason
                  of any default on the part of Sub-Sublessee by reason of which
                  the Prime Lease or Sublease may be terminated or forfeited, or
                  any claims shall accrue to the benefit of or for Prime
                  Landlord under the Prime Lease, and against any and all other
                  loss, cost, damage or expense incurred or suffered by
                  Sub-Sublessor or Sublessor as a result of or arising out of
                  the negligence of Sub-Sublessee or the failure of
                  Sub-Sublessee to act in accordance with this Sub-Sublease.

         8.                PAYMENTS TO SUB-SUBLESSOR BY SUB-SUBLESSEE.
                  Sub-Sublessee shall pay Sub-Sublessor, upon the execution
                  and delivery of this Sub-Sublease, the sum of Ten Thousand
                  One Hundred Twelve Dollars and Twenty-Five Cents ($10,112.75)
                  as a security deposit. Such security deposit shall be returned
                  to Sub-Sublessee within ten days of the end of the
                  Sub-Sublease Term unless Sub-Sublessor notifies Sub-Sublessee
                  within such ten-day period of a default or breach that
                  justifies not returning any such security deposit. If security
                  deposit is not returned in a timely manner Sub-Sublessor shall
                  pay Sub-Sublessee interest on any portion not returned at a
                  rate of one and one-half percent (1-1/2%) per month.

         10.               BROKERAGE. Sub-Sublessor and Sublessee (individually
                  hereafter, "Indemnitor") each represent and warrant to the

                  attorneys fees and costs, incurred by Indemnitee in
                  conjunction with any such claim or claims of any broker or
                  brokers claiming to have interested Sub-Sublessee in the
                  Building or Sublease Premises on behalf of Indemnitor or
