                  of its assets or become a party to dissolution proceedings;
                  provided, however, that no termination shall occur if any such
                  action is stayed, dismissed or reversed within sixty (60)
                  calendar days of the initiation of such action and the subject
                  Party provides satisfactory evidence of the same within such

by the following provision:

                  11.4. EFFECT OF TERMINATION UNDER SECTION 11.2(B). Upon a
                  termination of this Agreement under Section 11.2(b), the
                  Parties agree that the Joint Venture Company shall be
                  voluntarily dissolved and liquidated, provided that no
                  dissolution and liquidation shall occur upon such a
                  termination (or as otherwise provided in the Joint Venture
                  Company's Articles of Incorporation) if the non-bankrupt
                  holders of all of the remaining Shares elect to continue the
                  existence of the Joint Venture Company, in which case the
                  bankrupt holders shall vote with the non-bankrupt to approve
                  such continuance (including any necessary amendment of the
                  Articles of Incorporation to effect such continuance) and the
                  non-bankrupt holders shall purchase all (but not less than
                  all) of the Shares then owned by the bankrupt Party or any of
                  its direct or indirect wholly-owned Subsidiaries by serving
                  written notice to such Party and paying for such Shares in
                  accordance with Section 11.3. As a part of a dissolution and
                  liquidation, the non-bankrupt Party shall have the right (but
                  not the obligation) to purchase all, but not less than all, of
                  the assets of the Joint Venture Company at a price 



                  equal to the Fair Market Value thereof determined in
                  accordance with an Appraisal. The Party exercising its rights
                  under this Section 11.4 shall do so by serving written notice
                  to the other Party and the Joint Venture Company within thirty
                  (30) calendar days after the date of termination. The closing
                  shall be held within forty-five (45) days of the Parties'
                  receipt of the final appraisal of the assets of the Joint
                  Venture Company unless otherwise agreed by the Parties. The
                  purchase price of the assets purchased under this Section 11.4
                  must be paid in Japanese Yen in immediately available and
                  transferable funds through a transfer of funds to a banking
                  account to be designated at that time by the Joint Venture
                  Company. As a condition to the closing, the Parties shall
                  procure that the Joint Venture Company shall deliver to the
                  Party exercising its rights hereunder such instruments of
                  transfer as such Party may reasonably request, transferring
                  the assets free and clear of any lien or encumbrance other
                  than, with respect to real estate, encumbrances of record that
                  do not materially interfere with the use of the property for
                  the conduct of a retail store.


         17. In all other respects the JVA remains unmodified. In any conflict
or inconsistency between the provisions of this Agreement and the provisions of
the JVA, the provisions of this Agreement shall govern.

         IN WITNESS WHEREOF, each of the Parties has caused this Agreement to be
executed as of the date first above written by its duly authorized officer or
officers.
