Explanation of Anticipated Change

On March 12, 2004, pursuant to an Agreement and Plan of Merger (the "Merger
Agreement") dated as of March 11, 2004, by and among the Registrant (formerly
named Tintic Gold Mining Company), TTGM Acquisition Corporation, a Utah
corporation and wholly-owned subsidiary of the Registrant ("Merger Sub"), and
Kiwa Bio-Tech Products Group Ltd., a privately-held corporation organized in the
British Virgin Islands ("Kiwa Bio-Tech"), Merger Sub merged with and into Kiwa
Bio-Tech with Kiwa Bio-Tech surviving as a wholly-owned subsidiary of the
Registrant (the "Merger"). On March 17, 2004, the Registrant changed its name to
Kiwa Bio-Tech Products Group Corporation.

Prior the Merger, the Registrant did not conduct any significant business or
operations, and had only nominal revenues for the three months ended March 31,
2004. As a consequence of the Merger, Kiwa Bio-Tech's business and operations
comprise the overwhelming majority of the Registrant's business and operations.
The Registrant incurred a net loss of $1,650,247 for the three-month period
ended March 31, 2004 (on a consolidated basis) and expects to report a net loss
of approximately $161,183 for the three-month period ended March 31, 2005.
