            Property Rights except in conjunction with the M&S Services, and in
            accordance with any guidelines as may be issued by the Company from
            time to time and the terms of this Agreement. The foregoing
            notwithstanding, the Distributor may use the Intellectual Property
            Rights to market and distribute the Products as set forth in this
            Agreement. The Company reserves the right to require the Distributor
            to submit to the Company for prior approval any advertising and
            sales literature of
                                       9
            the Distributor that refers to the Products, or otherwise includes

                  the Distributor may or will infringe the proprietary rights of
                  a third party.
            (ii)  The Distributor agrees that it shall immediately notify the
                  Company of any infringement, illegal use or misuse by third

                  by the Distributor of any infringement, illegal use or misuse
                  by third parties of the Intellectual Property Rights or upon
                  the Company or the Supplier otherwise learning of such
                  infringement, illegal use or misuse by third parties, the
                  Company and/or the Supplier have the right and sole
                  discretion, but not the duty, to initiate any proceeding
                  relating to the protection of the Intellectual Property
                  Rights. Should the Supplier and/or the Company make such an
                  election to initiate proceedings, the Supplier and/or the
                  Company (as the case may be) shall bear the full burden of
                  expenses for such proceedings and shall also take the full
                  benefit, if any, of such proceedings. Furthermore, in the
                  event the Supplier and/or the Company should make such an
                  election, the Distributor shall provide all necessary
                  assistance required by the Supplier and/or the Company. The
                  Distributor shall be kept fully informed of the proceedings
                  but the Supplier and/or the Company shall retain full control
                  of the proceedings.

            shall not, and shall not have the right to, register, or apply for
            registration, anywhere in the world, directly or indirectly, any
            trade ▇▇▇▇, service ▇▇▇▇, trade name, copyright, company name or
            other proprietary or commercial right which is similar to the Trade
            Marks or take any other action that jeopardizes the Trade ▇▇▇▇
            owner's proprietary rights in the Trade Marks.
                                       10
      12.3  The Distributor shall at all times conduct business only under its
            own name and may not use any of the Trade Marks as part of its
            business name.
      12.4  The Distributor shall not attach, remove or disfigure any Trade
            Marks on the media containing the Product (or that appear as the
            result of executing the Product) nor attach any additional marks to
            the media containing the Product except as otherwise agreed by the
            Company in writing.
      12.5  The Distributor agrees not to alter, remove or obscure any copyright
            or other proprietary notices on or in the media containing the

            related documentation or materials.
      12.6  The Company reserves the right to require the Distributor to submit
            to the Company for prior approval any and all advertising and sales
            literature of the Distributor that refers to the Company, to the
            Products, or otherwise includes any of the Trade Marks. The
            Distributor shall make all modifications to the materials deemed
            necessary by the Company to protect the goodwill associated with the
            Trade Marks. The Distributor shall also comply with any guidelines
            relating to use of the Trade Marks as may be furnished to the
            Distributor and revised by the Company from time to time.
      12.7  The Distributor's right to use the Trade Marks shall immediately
            cease upon termination or expiration of this Agreement.
