          following rules:

          (1)  No buildings shall be erected on the land reserved for setback

          continuing to press for payment, the Lessor may also terminate the
          Agreement.

     8.   If the government adjusts the land value in accordance with
          relevant law, the rental charge shall be adjusted according to the
          new land value beginning on the first day of the month following the
          month in which the new land value was announced, and the Lessee shall
          raise no objection thereto.

          other building, the Lessee shall complete the construction within
          three months of the execution of this Agreement, and shall complete
          construction of the building in accordance with the plan. If the
          Lessee does not begin construction of the building on schedule, or
          if, after applying for an extension, the Lessee still fails to begin
          construction within the new time limit, or if the Lessee fails to
          complete construction in accordance with the plan, the Lessor may
          terminate the Agreement and take back the land. Any rental charges
          and public utilities construction charges already paid will not be
          returned to the Lessee. If there are any uncompleted buildings on the
          land, the Lessor may dispose of these in accordance with the law, or
          may require the Lessee to remove them; the Lessee shall raise no
          objection to this, and may not refuse to remove the buildings if

          Lessee needs to dig up the roads, drainage pipes (or water supply
          pipes) or other public facilities in the Export Processing Zone, it
          shall apply to the Lessor for approval in advance and shall pay a
          deposit. Once the work has been completed and the public facilities
          restored to their original condition, the deposit will be returned,
          without interest; the deposit will not be returned if the above
          requirements are violated.

          (1)  If the Lessee uses the land in a way which violates any of the
               provisions of this Agreement;

          (2)  If the buildings belonging to the Lessee are purchased by price
               negotiation or compulsory purchase in accordance with Article 12
               of the Regulations Governing the Establishment and Management of
               Export Processing Zones;

          (3)  If the Lessee is in arrears in the payment of the rental charge
               and other charges by four months or more; or

          (4)  If any other circumstances arise which permit the termination of
               the Agreement in accordance with the Civil Code or with the Land
               Law.

     12.  If the Agreement is terminated in accordance with the preceding
          Article, the land shall be returned immediately. If there are any
          buildings belonging to the Lessee on the land, the buildings shall be
          sold within two years to another enterprise operating in the Export
          Processing Zone approved by the Export Processing Zone Administration
          or its branch office; the land rental charge for the period up until
          sale of the buildings shall be paid in accordance with Article 7 of
          this Agreement. If the Lessee fails to dispose of the buildings in
          accordance with this Article, or if the disposal procedures have not
          been completed after two years, the Lessor may handle the matter in
          accordance with the law, or may purchase by price negotiation all
          facilities and goods belonging to the Lessee within the buildings on
          the rented land; the Lessee shall raise no objection thereto.

     13.  If, on the expiry of this Agreement, the Lessee wishes to renew the
          Agreement, it shall submit a written application for renewal of the
          Agreement to the Lessor at least three months prior to the expiration
          of the Agreement. If the Lessee does not apply to renew the Agreement
          by the expiry of the Agreement, the Lessee shall return the land
          immediately on the expiry of the Agreement. Any buildings belonging
          to the Lessee on the leased

          Administration or its branch office; the land rental charge for the
          period up until sale of the buildings shall be paid in accordance
          with Article 7 of this Agreement. If the Lessee fails to dispose of
          the buildings in accordance with this Article, or if the disposal
          procedures have not been completed after six months, it shall be
          deemed to breach the Agreement. The Lessor may dispose or purchase
          all buildings belonging to the Lessee on the leased land and all
          facilities and goods within the buildings in accordance with the law;
          the Lessee shall raise no objection thereto.
