DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (this “Post-Effective Amendment”) relates to the registration statement on Form S-8 (File No. 333-171454) (the “Registration Statement”), which was filed with the U.S. Securities and Exchange Commission by Youku Tudou Inc., a company established under the laws of the Cayman Islands (the “Registrant”), and became effective on December 29, 2010. Under the Registration Statement, a total of 240,441,231 class A ordinary shares of the Registrant, par value $0.00001 per share, were registered for issuance of shares granted or to be granted pursuant to the Registrant’s 2006 Stock Option Scheme, as amended (the “2006 Plan”). This Post-Effective Amendment is being filed for the sole purpose of deregistering any unissued shares previously registered under the Registration Statement and issuable under the 2006 Plan.

On November 6, 2015, the Registrant, Ali YK Investment Holding Limited (“Parent”), Ali YK Subsidiary Holding Limited (the “Merger Sub”) and, solely for purposes of Section 9.08, Section 9.09 and Section 9.10 thereof, Alibaba Investment Limited entered into an agreement and plan of merger, which was approved on March 14, 2016 by the shareholders of the Registrant at an extraordinary general meeting of shareholders. The Registrant and Merger Sub subsequently filed a plan of merger with the Registrar of Companies of the Cayman Islands on April 5, 2016, which became effective as of April 5, 2016 (the “Effective Time”), as a result of which Merger Sub was merged with and into the Registrant, with the Registrant continuing as the surviving corporation and becoming a wholly owned subsidiary of Parent (the “Merger”).

As a result of the Merger, the Registrant has terminated all the offerings of its securities pursuant to the Registration Statement. The Registrant hereby removes from registration, by means of this Post-Effective Amendment, any and all of the securities registered under the Registration Statement which remain unsold or unissued as of the Effective Time.
