Item 1.02 - TERMINATION OF A MATERIAL DEFINITIVE AGREEMENT

As previously reported by Tradestream Global Corp. (formerly Vianet Technology
Group Limited) ("Registrant") through news releases on July 1, 2005 and July
7, 2005, and a Current Report on Form 8K filed on July 7, 2005, the Registrant
had entered into an agreement of merger with Vianet Direct, Inc., with the
transaction being subject to the execution and approval of a definitive merger
agreement as well as certain closing conditions and due diligence requirements.

As the Registrant and Vianet Direct, Inc. were not able to agree upon the
definitive terms and conditions of the merger or the due diligence procedures,
the Board of Directors of the Registrant, at a Special Meeting held on July 22,
2005, formally approved the decision by Management of the Registrant to
terminate such merger negotiations with Vianet Direct, Inc., and the Registrant
is currently proceeding with negotiations with other prospective merger or
acquisition candidates.


ITEM 5.03 - AMENDMENTS TO ARTICLES OF INCORPORATION OR BY-LAWS

The Registrant has amended its Certificate of Incorporation to change its name
to Tradestream Global Corp. effective immediately.  The Registrant's new OTC
trading symbol as of Thursday, July 28, 2005 is "TGLC".

Pursuant to the Requirements of the Securities Exchange Act of 1934, the

undersigned hereunto duly authorized.
