     During the past five years, no member of the Reporting Group (including

criminal proceeding (excluding traffic violations or similar misdemeanors), or
(b) a party to a civil proceeding of a judicial or administrative body of 
competent jurisdiction and as a result thereof was or is subject to a

Item 3. Source and Amount of Funds or Other Consideration

     At the time of filing of Amendment No. 5 to this Schedule 13D ("AM 5"), 
Mr. Leung directly owned 726,678 Ordinary Shares of the Issuer.  Since the 
filing of AM 5, Mr. Leung sold 101,905 of the Issuer's Ordinary Shares at 
prices ranging from $3.09 to 4.83.  These sales, when coupled with the 
Reporting Event (described below), resulting in Mr. Leung directly owning 
724,773 Ordinary Shares of the Issuer.  Mr. Leung possesses options to 
purchase the number of Issuer's ordinary shares as indicated pursuant to the 
following plans and at the prices indicated opposite the plan names:  


                                                   Exercise Price
Plans                      Number of Shares            (US$) 
-----                      ----------------         ------------

Management Options            2,457,000                1.6789
                                866,600                 1.221

2000 and 2002 Officers'  (a)    567,000                0.5857
and Directors' Plans                                        
                         (b)    205,800                0.8191
                            ----------- 
                              4,096,400

     The Issuer's 2000 and 2002 Officers and Directors Plans both contain 
"cashless" exercise provisions permitting the optionholder to pay for the 
exercise of his option by surrendering Ordinary Shares valued at the fair 
market value of such shares on the date of exercise, provided that such shares
were held by the optionholder for not less than six months prior to the date 
of exercise of the option.

     Mr. Leung has exercised 100,000 options exercisable at $1.221 per share 
granted to him pursuant to the Management Option Plan of the Issuer by the 
payment in cash for an aggregate exercise price of $122,100.00.  As a 
consequence, Mr. Leung's ownership changed by with the Issuer, issuing to him 
100,000 new shares (the "Reporting Event").  The shares owned directly by Mr. 
Leung changed from 726,678 shares to 724,773 shares.  His options decreased by 
100,000 from 4,196,400 options to 4,096,400 options.

                                                                Page 8 of 10

Item 5. Interest in Securities of the Issuer

     As of the date hereof, the aggregate number of shares held of record by 
all members of the Reporting Group is 7,855,146 or approximately 70.0% of the
Issuer's issued and outstanding Ordinary Shares.

     Mr. Leung possesses sole voting and dispositive power as to 724,773 of 
the Issuer's Ordinary Shares owned by him and as to the options to purchase 
4,096,400 of the Issuer's Ordinary Shares.

     Regent and Pearl share voting and dispositive power as to the Ordinary 
Shares owned of record by Regent (274,582 shares or 3.9% of the Issuer's 
Ordinary Shares). When Pearl's record ownership (2,759,391 shares) is 
aggregated with its beneficial ownership in the shares held in the name of 
Regent, Pearl beneficially owns 3,033,973 shares or 42.6% of Issuer's Ordinary 
Shares.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect 
to Securities of the Issuer

	None.
