occupancy, which is planned to begin on January 1, 2004 (the "COMMENCEMENT

                                                       MONTHLY RENT
                  Occupancy-- 10/31/04                  $4,660.83
                  11/01/04-- 10/31/05                   $4,847.26
                  11/01/05-- 10/31/06                   $5,041.15

plus state sales tax as then applicable in Broward County, Florida as of the
date of payment, in advance on the first day of each month of the Term. If the
Term begins or ends on a day other than the first or last day of a month, the
rent for the partial month or months shall be prorated on a per diem basis, with
the numerator being the number of days that the Sublessee has occupied or will
occupy the Premises and the denominator being the number of days in the relevant
month. The Sublessee shall not be responsible for any Additional Rent as
outlined in the Master Lease. Unpaid rent shall bear interest until paid at the
prime rate of interest plus 2%.

         6. TENANT IMPROVEMENTS. Sublessor shall provide the Premises in an
"as-is" condition.

         7. SECURITY DEPOSIT AND FIRST MONTH OF RENT.

         (a) Sublessee shall deposit with Sublessor upon the signing of this
Agreement, the sum of $0.00 as security of its faithful performance of its
obligations hereunder ("SECURITY DEPOSIT") plus $4,660.83 as payment of the
first month of rent due under this Agreement. Total due upon signing is
$4,660.83.

         (b) If Sublessee fails to pay Rent or other charges when due under this
Agreement, or fails to perform any of its other obligations hereunder, Sublessor
may use or apply all or any portion of the Security Deposit, without prejudice
to any other remedy which Sublessor may have, for the payment of any Rent or
other amount then due hereunder and unpaid, for the payment of any other sum for
which Sublessor may become obligated by reason of Sublessee's default or breach,
or for any loss or damage sustained by Sublessor as a result of Sublessee's
default or breach.

         (c) If Sublessor so uses any portion of the Security Deposit, Sublessee
shall, within 10 days after written demand by Sublessor, restore the Security
Deposit to the full amount originally deposited, and Sublessee's failure to do
so shall constitute a default under this Agreement. Sublessor shall not be
required to keep the Security Deposit separate from its general accounts, and
shall have no obligation or liability for payment of interest on the Security
Deposit. In the event Sublessor assigns or otherwise conveys its interest in


                                      -2-
<PAGE>

this Agreement, Sublessor shall deliver to its assignee so much of the Security
Deposit as is then held by Sublessor and Sublessee agrees to look solely to such
grantee or assignee for application or return of the Security Deposit from any
mortgagee or any purchaser of Sublessor's interest as a foreclosure sale of any
grantee of a deed in lieu of foreclosure.

         (d) Within 30 days after the Term has expired, or Sublessee has vacated
the Premises, whichever shall last occur, and provided Sublessee is not then in
default of any of its obligations hereunder, the Security Deposit, or so much
thereof as had not theretofore been applied by Sublessor, shall be returned to
Sublessee or to the last assignee, if any, of Sublessee's interest hereunder.

         8. USE OF PREMISES. The Premises shall be for general office use.

         9. ASSIGNMENT AND SUBLETTING. Sublessee shall not mortgage, encumber,
assign, convey or sublet this Agreement or any interest thereunder in any manner
which would constitute a breach or violation of either of the Leases and without
the prior written consent of Sublessor, such consent shall not be unreasonably
withheld, and the consent of Lessor, as required under the terms of either of
the Leases; HOWEVER, it is understood by the parties hereto that the Sublessee
intends to assign its rights and responsibilities under this Agreement to its
wholly-owned subsidiary, Splinex Technology Inc., and the Sublessor hereby
approves of such an assignment.

terminate either of the Master Leases 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 or breach hereunder.

the same grace period provided to Sublessee.
