filed with the SEC at various times through January 19, 2007.

	The class of securities to which this Schedule 13D relates is the
ordinary shares, par value $.01 per share (the "Ordinary Shares"), of EURO

Item 2. Identity and Background

	This statement is being filed by a group consisting of T.C. Leung,
Pearl Venture Ltd. ("Pearl") and Regent Earning Ltd. ("Regent") (the
"Reporting Group"). Pearl is a British Virgin Islands corporation which is
a trust for the benefit of Mr. Leung. Regent is a Hong Kong corporation of
which Pearl is the majority shareholder.  Mr. Leung is Chairman of the
Board and Chief Executive Officer of the Issuer.

	The respective business addresses of the members of the Reporting
Group are as follows:

    Name                   Address
    ----                   -------

                           18/F Gee Change Hong Centre
                           65 Wong Chuk Hang Road
                           Hong Kong

    Pearl Venture Ltd.     Columbus Centre Building
                           Wickhams Cay
                           Road Town, Tortola,
                           British Virgin Islands

(a) convicted in a criminal proceeding (excluding traffic violations
or similar misdemeanors), or (b) a party to a civil proceeding of a

                                                         Page 7 of 10

	Mr. Leung is a citizen of Hong Kong. Pearl is a British Virgin
Islands corporation. Regent is a Hong Kong corporation.

Item 3. Source and Amount of Funds or Other Consideration

	At the time of filing of Amendment No. 9 to this Schedule 13D
("AM 9"), Mr. Leung directly owned 2,373,000 Ordinary Shares of the
Issuer. After the Reporting Event (described below), Mr. Leung directly
owns 4,085,200 Ordinary Shares of the Issuer.  Mr. Leung possesses
options issued under 2002 Officers' and Directors' Plans to purchase
567,000  of Issuer's ordinary shares at an exercise price of $0.5875
per share


	The Issuer's 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 1,700,000 options exercisable at $1.6789 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 $2,854,130 from his
personal funds.  As a consequence, Mr. Leung's ownership changed by with the
Issuer, issuing to him 1,700,000 new shares. Mr. Leung also bought 12,200 of
the Issuer's Ordinary Shares at prices ranging from $2.57 to $2.61 in the
open market (the "Reporting Event").  The shares owned directly by Mr. Leung
changed from 2,373,000 shares to 4,085,200 shares.  His options decreased by
1,700,000 from 2,267,000 options to 567,000 options.

	At the time of filing of Amendment No. 9 to this Schedule 13D
("AM 9"), Pearl directly owned 1,866,298 Ordinary Shares of the Issuer.
Since the filing of AM 9, Pearl sold 498,957 of the Issuer's Ordinary
Shares at prices ranging from $2.55 to $3.9 in the open market. After
these sales, Pearl directly owns 1,367,341 Ordinary Shares of the Issuer.




Item 4. Purpose of Transactions

	Investment purposes.

Item 5. Interest in Securities of the Issuer

	As of the date hereof, the aggregate number of shares beneficially
held by all members of the Reporting Group is 6,308,623 or approximately
53.4% of the Issuer's Ordinary Shares after giving effect to the exercise
of options held by the members of the Reporting Group.





                                                         Page 8 of 10

	Mr. Leung possesses sole voting and dispositive power as to
4,085,200 of the Issuer's Ordinary Shares owned by him and as to the
options to purchase 567,000 of the Issuer's Ordinary Shares.

	Regent and Pearl share voting and dispositive power as to the
Ordinary Shares owned of record by Regent (289,082 shares or 2.6% of the
Issuer's Ordinary Shares). When Pearl's record ownership (1,367,341 shares)
is aggregated with its beneficial ownership in the shares held in the name
of Regent, Pearl beneficially owns 1,656,423 shares or 14.7% of Issuer's
Ordinary Shares.

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

	None.

Item 7. Material to be Filed as Exhibits

	Agreement among the Reporting Group to file a single Statement on
Schedule 13D on behalf of each of them.
