Chai-Na-Ta Corp. Announces Share Conversion by Major Investor

RICHMOND, BRITISH COLUMBIA – December 1, 2003 – Chai-Na-Ta Corp. (TSX: “CC”; OTCBB: “CCCFF”), the world’s largest supplier of North American ginseng, announced that its major investor, Herb King International Limited, today converted 10,000,000 non-voting preferred shares into common shares, thereby raising its holdings of Chai-Na-Ta’s common shares to 78% from 62%.

Herb King, a wholly owned subsidiary of Road King Infrastructure Limited of Hong Kong, retains 10,399,149 preferred shares, which are convertible into common shares on a one-for-one basis.

“The share conversion underscores our confidence in Chai-Na-Ta’s future, as the outlook for the Company and the ginseng industry continue to brighten,” said William Zen, Chairman and Chief Executive Officer.

A total of 20,399,149 non-voting, convertible preferred shares were issued to John Hancock Life Insurance Company in April 2000 in settlement of certain secured debts owed to it by Chai-Na-Ta. Later that month, through a financial restructuring and change of control, Herb King took ownership of the shares.

Chai-Na-Ta Corp., based in Richmond, British Columbia, is the world’s largest supplier of North American ginseng. The Company farms, processes and distributes North American ginseng as bulk root, and supplies processed material for the manufacture of value-added ginseng-based products.
