EXPLANATORY NOTE:  DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (the “Post-Effective Amendment”) relates to the Registration Statement on Form F-3 (File No. 333-160287) (the “Registration Statement”), which was filed with the Securities and Exchange Commission by VanceInfo Technologies Inc., a company established under the laws of the Cayman Islands (the “Company”), and became effective on July 8, 2009. The Registration Statement registered for sale by the Company and the selling shareholders named in the Registration Statement and any supplement thereto a total of 8,200,000 ordinary shares, par value $0.001 per share, of the Company (the “Ordinary Shares”) which may be represented by the American depositary shares of the Company (the “ADSs”, and together with the Ordinary Shares, the “Securities”) .

Pursuant to an agreement and plan of merger dated August 10, 2012, as amended by the amendment dated August 31, 2012 (the “Merger Agreement”), by and among HiSoft Technology International Limited (“HiSoft”), the Company, Chemistry Merger Sub Inc., a wholly owned subsidiary of HiSoft, and Chemistry Merger Sub II Inc. (“Merger Sub II”), a wholly owned subsidiary of HiSoft, and the plans of merger, dated November 9, 2012 between (i) the Company and Merger Sub; and (ii) the Company and Merger Sub II, the Company became a wholly owned subsidiary of HiSoft, and Hisoft’s name was changed from HiSoft Technology International Limited to Pactera Technology International Ltd (“Pactera”) on November 9, 2012. As a result of the merger, each Ordinary Share of the Company issued and outstanding immediately prior to the effective time of the merger has been cancelled in exchange for the right to receive one common share of Pactera, and each American depositary share of the Company representing one Ordinary Share, has been cancelled in exchange for the right to receive one American depositary share of Pactera.

As a result of the merger, the Company has terminated all offerings of the securities pursuant to its existing registration statements, including the Registration Statement. Accordingly, by means of this Post-Effective Amendment, the Company hereby terminates the effectiveness of the Registration Statement and, in accordance with an undertaking made by the Company in Part II of the Registration Statement to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offering, removes from registration any and all Securities registered but unsold under the Registration Statement as of the date hereof.
