                          TO THE DISTRIBUTION AGREEMENT
         BETWEEN UBI SOFT ENTERTAINMENT S.A. & BAM ENTERTAINMENT LIMITED


This Amendment #1 (the "Amendment #1") to the Distribution Agreement (the
"Agreement") entered into by and between Bam Entertainment Limited, whose
principal place of business is located at 17 Burlington Street, Bath, Avon &
Somerset BA1 2SB ("BAM") and Ubi Soft Entertainment S.A., whose principal place
of business is located at 28, rue Armand Carrel, 93108 Montreuil sous Bois cedex
and whose registered office is located at 107, Avenue Henri Freville, BP 10704,
Rennes (35207) CEDEX ("UBI SOFT"), dated July 31, 2001 is entered into effective
as of August 5, 2002 (the "Effective Date").
(BAM and UBI SOFT being jointly referred to as the "Parties")

The Parties have signed the Agreement whereby BAM grants to UBI SOFT an
exclusive license to distribute, market and sell the Products and Promotional
Materials throughout any Distribution Channel, on the Territory during the Term.

BAM has informed UBI SOFT that it wishes to contract firm sales with
Sub-Distributors (as further defined below) in Germany and Italy.

Accordingly, the Parties wish to amend the Agreement to provide for specific
terms and conditions regarding these firm sales (the "Sub-Distribution Deals",
alternatively hereinafter referred to as the "Purpose").

THEREFORE UBI SOFT and BAM agree as follows:

1. SCOPE OF THIS AMENDMENT #1: SUB-DISTRIBUTION DEALS.

UBI SOFT grants BAM as of the Effective Date the right to contract firm sales
with the company Konami in Germany and the company Leader in Italy (the
"Sub-Distributors") regarding the Products listed in Schedule A-1 attached
hereto (the "Sub-Distribution Products") as follows:

--------------------------------------------------------------------------------
                        COUNTRIES OF THE
   SUB-DISTRIBUTOR         TERRITORY             SUB-DISTRIBUTION PRODUCTS

<S>                      <C>                <C>

--------------------------------------------------------------------------------
   Leader                  Italy            Products referred to in Schedule A-1
--------------------------------------------------------------------------------
</TABLE>


The Sub-Distribution Products shall be purchased from BAM by Sub-Distributors at
the purchase prices indicated in Schedule A-1 (the "Purchase Prices") and be
sub-distributed and sold by Sub-Distributors until expiration of the Term as set
forth in Clause 7 of the Agreement in the quantities detailed in Schedule A-1
(which may change upon mutual agreement between BAM and the concerned
sub-distributor and subject to UBI SOFT's prior written approval in each
instance). Any subsequent orders of Sub-Distribution Products by
Sub-Distributors shall be treated as per the terms and conditions of this
Amendment #1.

Accordingly, pursuant to Clause 2.3 of the Agreement, as of the Effective Date
UBI SOFT shall distribute exclusively through the Sub-Distributors only the
Sub-Distribution Products throughout Germany and Italy, and keep the direct
distribution of the Products under the Agreement as per the terms of the
Agreement. In the event any of the contracts entered by and between BAM and the
Sub-Distributors with respect to the sub-distribution of the Sub-Distribution
Products is terminated before the Term for any reason, UBI SOFT shall
automatically have the right to distribute the Sub-Distribution Products direct
to the distribution channels from the date of such termination until expiration
of the Term pursuant to the terms and conditions of the Agreement.

2. DELIVERY OF THE PRODUCTS BY BAM.

The Parties agree that with respect to the Purpose only:

        - each Sub-Distributor shall issue and sign purchase orders (whether for
        initial or additional orders) which are tripartite between BAM, UBI SOFT

        - BAM shall be solely responsible for all logistics relating to the

        corresponding Sub-Distributor warehouses : (1) "cash on delivery" in
        Germany, (2) 30 days from date of invoice in Italy. The

        transfer from the remuneration payable by Sub-Distributor an "Amendment
        Distribution Services Fee" (as defined in clause 3.d. of this Section)
        equal to UBI SOFT's fee for its services under this Amendment #1.

        b) The remuneration paid to BAM by each Sub-Distributor shall be
        directly negotiated between BAM and the Sub-Distributor, on a firm sale
        basis, at the Purchase Prices indicated in Schedule A-1, without the
        intermediate of UBI SOFT.

        c) UBI SOFT shall bear no responsibility nor liability as of the
        Effective Date with respect to any bad debts and amount invoiced by BAM
        to any Sub-Distributor which remains unpaid by Sub-Distributor.

        d) In consideration of the services provided by UBI SOFT to BAM as
        intermediate, UBI SOFT shall be entitled to a specific distribution
        services fee of [*] of Sub-Distributor's Net Revenues. For the purpose
        of this Amendment #1, Sub-Distributor's Net Revenues shall be defined as
