       the use by other joint venture companies.

       1.5% of sales of "HVM" products which shall be paid quarterly.

5.     This Agreement shall have a term of 3 years and shall be automatically
       renewed for another 3 years if both parties do not raise any changes.

       shall not terminate this Agreement. If Party A requests to terminate this
       Agreement upon expiration, it shall give Party B three-month notice in
       advance.

7.     Upon expiration of this Agreement, if Party A requests Party B to
       transfer the ownership of the "HVM" trademark, Party B shall transfer at
       a price not more than the total usage fee of the "HVM" trademark in the
       previous three years based on 1.5% on sales as agreed by both parties.

8.     Both parties agree to protect the goodwill of the "HVM" trademark and
       shall not do anything to impair the "HVM" trademark.
