Bestip Development International Limited Emerges as Publicly-Traded Company Through Closing of Reverse Acquisition of Wyoming Oil & Minerals, Inc.

HONG KONG -- Bestip Development International Limited ("Bestip"), a designer and manufacturer of micro motors, today announced it has completed the closing of its reverse acquisition of Wyoming Oil & Minerals, Inc (OTCBB: WYOI), pursuant to which WYOI acquired all of the outstanding ordinary shares of Bestip in exchange for a controlling interest in WYOI. Through the reverse acquisition, Bestip will become a publicly-traded company.

Pursuant to a securities purchase agreement between the parties, the shareholders of Bestip have transferred to WYOI all of the outstanding capital shares of Bestip in exchange for WYOI's issuance of 28,000,000 shares of its common stock to the shareholders of Bestip (representing approximately 95% of WYOI's total capital stock outstanding after giving effect to its acquisition of Bestip).

In conjunction with the closing of the reverse acquisition, existing members of Bestip's management team, Simon Shi and Jeffrey Shi, have been elected to the board of directors of WYOI, replacing Bill M. Conrad, Jubal S. Terry and Raymond E. McElhaney, who resigned effective at the closing of the acquisition. Further, it is anticipated that WYOI will change its name to "Sun Motor Technology, Inc.", which will also result in a change to its stock symbol.

Incoming Chairman of Wyoming Oil, Mr. Simon Shi said "We are very pleased to have completed our public listing in the United States. As one of the world's leading manufacturers of micro motors with annual revenues of over $40 million, with a significant portion of our client base comprising US and European corporations, we believe that our shareholders will be very satisfied with the new business structure of their company."

For its fiscal year ending March 31, 2004, Bestip had revenues of $39,965,957 and net income of $1,078,911.
