      by the Mortgagor.


                                      -4-


7.    ENFORCEMENT OF MORTGAGE

7.1   The enforcement of the Mortgage and the distribution of proceeds realized
      thereon shall be in accordance with the procedures set forth in the
      Security Sharing Agreement.

7.2   As per the Security Sharing Agreement, the Mortgagee will act to enforce
      the Mortgage on behalf of the Mortgagee upon receipt of (i) a Notice of
      Actionable Default (as defined in the Security Sharing Agreement) and (ii)
      written instruction from the Required Holders (as defined in the Security
      Sharing Agreement). Upon receipt of the above, the Mortgagee may proceed
      to seek a court order declaring the Mortgagor in default of its
      Obligations and that the Mortgaged Property shall be sold at public
      auction or take any other action permitted by law or as mutually agreed by
      the parties.

7.3   The Mortgagee may select to sell any or all of the Land to be enforced as
      it deems appropriate.

7.4   As per the Security Sharing Agreement, the net proceeds derived from a
      sale of any or all of the Mortgaged Property shall be applied towards
      settlement of the Obligations. If such proceeds or the value of the Land
      in case of foreclosure are insufficient to pay or set off all amounts to
      which the Mortgagee are entitled, the Mortgagor shall remain liable for
      the deficiency. All such proceeds shall be distributed in accordance with
      the Security Sharing Agreement.

7.5   If the Mortgage is enforced, the Mortgaged Amount stated herein shall not
      prejudice the right of the Mortgagee to apply all of the net proceeds
      derived from a sale of any or all of the Mortgaged Property, whether or
      not such proceeds or value exceeds the Maximum Amount, towards settlement
      of the Obligations.

7.6   If the Mortgagee enforces the mortgage or forecloses the Mortgaged
      Property and tax liabilities of any kind (including but not limited to
      customs duty, value added tax and transfer fees) related to the Mortgaged
      Property arise for which the Mortgagee are liable, the Mortgagor shall
      immediately pay such tax liabilities and all related penalties and
      expenses and/or reimburse the Mortgagee for said amounts if paid by the
      Mortgagee.

8.    COVENANTS

            regulations of the Government of Thailand and all the subdivisions

            condition of the Mortgagor and with all further laws, announcements,
            decrees or regulations subsequently issued from time to time which
            may affect the Mortgaged Property except where such failure to
            comply would not have a material effect on the business or general
            condition of the Mortgagor.

      (2)   Not to do or permit or consent to be done or omit anything with the
            knowledge that the consequence thereof may in any material way cause

            material respect or cause any policy of insurance effected in
            pursuance of the provisions of the mortgage or the Land Mortgage
            Agreement to be cancelled or the amount of any premium payable for
            any such policy of insurance to be materially increased.

            except as to any such right as would not in the good faith judgment
            of the Mortgagee have a material adverse affect on the value of the
            Mortgaged Property.

      (4)   Not to make or permit to be made without the written consent of the
            Mortgagee any material structural alteration or addition to the

            value of the Mortgaged Property.

            a copy thereof to the Mortgagees, and on demand by the Mortgagee to
            supply to the Mortgagee all material information within the
