Introductory Statement

This Amendment No. 1 (this “Amendment”) is being filed by Ali YK Investment Holding Limited (“Ali YK”), Alibaba Investment Limited (“AIL”) and Alibaba Group Holding Limited (“AGHL”, and together with Ali YK and AIL, the “Alibaba Reporting Persons”) and hereby amends the Schedule 13D initially filed by the Alibaba Reporting Persons, YF Venus Ltd, Yunfeng Fund II, L.P., Yunfeng Investment II, L.P., Yunfeng Investment GP II, Ltd. and Yu Feng on May 29, 2014 (the “Original Filing”) relating to the Class A ordinary shares, par value US$0.00001 per share (the “Class A Shares”), of Youku Tudou Inc., an exempted company with limited liability incorporated under the laws of the Cayman Islands (the “Issuer”), with respect to the Alibaba Reporting Persons. The Class A Shares are represented by American Depositary Shares (“ADSs”), with each ADS representing 18 Class A Shares. Information reported in the Original Filing with respect to the Alibaba Reporting Persons remains in effect except to the extent that it is amended or superseded by information contained in this Amendment. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Original Filing.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 is hereby amended and supplemented by adding the following at the end thereof:

On October 16, 2015, AGHL submitted a non-binding proposal (the “Proposal Letter”) to the Issuer’s board of directors relating to the proposed acquisition of all of the outstanding Ordinary Shares and ADSs, other than the Alibaba Owned Shares (being 643,161,852 Class A Shares), in a going private transaction, for cash consideration of US$26.60 per ADS (or equivalent amount per Class A and Class B ordinary share, as the case may be) based on the Issuer’s share capital set forth in the Issuer’s public filings (the “Proposed Transaction”). The Alibaba Reporting Persons anticipate that the consideration payable in connection with the Proposed Transaction will be funded by cash on hand.

The description of the Proposal Letter contained herein is qualified in its entirety by reference to Exhibit F, which Exhibit is incorporated herein by reference.

Item 4. Purpose of Transaction

Item 4 is hereby amended and supplemented by adding the following at the end thereof:

On October 16, 2015, AGHL submitted the Proposal Letter to the Issuer’s board of directors relating to the Proposed Transaction. Consummation of the transactions contemplated by the Proposal Letter is subject to a number of conditions, including, among other things, the negotiation and execution of definitive agreements and other related agreements mutually acceptable in form and substance to the Issuer and AGHL. None of the Issuer, any of the Alibaba Reporting Persons or any affiliate of any Alibaba Reporting Persons is obligated to complete the Proposed Transaction, and a binding commitment with respect to the Proposed Transaction will result only from the execution of definitive agreements, and then only on the terms provided in such agreements.

In the Proposal Letter, AGHL stated that AGHL has a right of first offer with respect to a change of control transaction involving the Issuer, including any merger or sale of the Issuer, that it is interested only in pursuing the Proposed Transaction and that it does not intend to sell its stake in the Issuer to any third party.

If the Proposed Transaction is consummated, the ADSs would be delisted from New York Stock Exchange, and the Issuer’s obligation to file periodic reports under the Exchange Act would terminate. In addition, the Proposed Transaction could result in one or more of the actions specified in clauses (a)-(j) of Item 4 of Schedule 13D, including the acquisition or disposition of securities of the Issuer, a merger or other extraordinary transaction involving the Issuer, a change to the board of directors of the Issuer (as the surviving company in the merger) to consist of persons to be designated by the Alibaba Reporting Persons, and a change in the Issuer’s memorandum and articles of association to reflect that the Issuer would become a privately held company.

Concurrent with the submission of the Proposal Letter, AIL has entered into a support agreement (the “Support Agreement”) with Victor Wing Cheung Koo, 1Verge Holdings Ltd., 1Look Holdings Ltd., The Koo 2012 Irrevocable Children’s Trust, Chengwei Partners, L.P., Chengwei Evergreen Capital, L.P. and Chengwei Ventures Evergreen Advisors Fund, LLC (collectively, the “Supporting Parties”), who, collectively with AIL, own approximately 36.9% of the issued and outstanding Ordinary Shares representing approximately 59.3% of the total voting power thereof. Pursuant to the Support Agreement, each Supporting Party has agreed, among other things, during the term of the Support Agreement, solely in its capacity as the beneficial owner of its Ordinary Shares, (i) to vote or cause to be voted all of its Ordinary Shares (including Ordinary Shares represented by ADSs): (a) in favor of the approval, adoption and authorization of the merger agreement relating to the Proposed Transaction as may be entered into between AGHL and/or one or more of its affiliates, on one hand, and the Issuer, on the other hand, in the form to be agreed by such parties (the “Merger Agreement”) and the approval of the Proposed Transaction and any other transactions contemplated by the Merger Agreement, (b) in favor of any other matters required to consummate the Proposed Transaction and any other transactions contemplated by the Merger Agreement, (c) against any competing acquisition proposal or any other transaction, proposal, agreement or action made in opposition to the Proposed Transaction or in competition or inconsistent with the Proposed Transaction, and (d) against any other action, agreement or transaction that is intended to facilitate a competing acquisition proposal or that is intended to or could prevent, impede, or, in any material respect, interfere with, delay or adversely affect the Proposed Transaction or any other transactions contemplated by the Merger Agreement or the performance by such Supporting Party of its obligations under the Support Agreement, and (ii) not to, and use its reasonable efforts to cause its representatives not to, (w) directly or indirectly, make any competing acquisition proposal or join with, or invite, any other person to be involved in the making of any competing acquisition proposal, (x) provide any information to any third party with a view to such third party or any other person pursuing or considering to pursue a competing acquisition proposal, (y) finance or offer to finance any competing acquisition proposal, including by offering any equity or debt financing, or contribution of any Ordinary Shares or provision of a voting agreement, in support of any competing acquisition proposal, or (z) solicit, encourage or facilitate, or induce or enter into any negotiation, discussion, agreement or understanding with any person (other than AIL and its affiliates) regarding a competing acquisition proposal or any of the matters described in this paragraph.

In addition, pursuant to the Support Agreement, each Supporting Party irrevocably and unconditionally appointed AIL and/or any designee of AIL, as its proxies and attorneys-in-fact, with full power of substitution and resubstitution, to vote, act by written consent or execute and deliver a proxy during the term of the Support Agreement solely in respect of the matters described in the immediately preceding paragraph. Each Supporting Party further agreed, during the term of the Support Agreement, not to sell, transfer, pledge, or otherwise dispose of any Ordinary Shares and ADSs beneficially owned by such Supporting Party, except for those transfers permitted under the Support Agreement.

The obligations under the Support Agreement terminate, in respect of a Supporting Party, upon the earliest to occur of (i) the consummation of the Proposed Transaction, (ii) the date on which AIL informs the Board (or a special committee thereof formed to consider the Proposed Transaction), or publicly discloses, that the board of directors of AGHL has resolved to terminate or rescind the Proposal Letter or discontinue its pursuit of the Proposed Transaction, (iii) the date on which (a) AGHL or AIL publicly discloses an amendment to the Proposal Letter or (b) or the Issuer, on the one hand, and AIL and/or its affiliates, on the other hand, execute and deliver to each other a definitive merger agreement in relation to an acquisition, in each case, pursuant to which (A) the per Ordinary Share purchase price or per ADS purchase price to be paid by AIL and/or its affiliates would be less than the price per Ordinary Share and price per ADS, respectively, set forth in the original Proposal Letter, except for any lower price agreed in writing by the Supporting Parties, and/or (B) AIL and/or its affiliates will acquire less than all of the outstanding Ordinary Shares and ADSs not already beneficially owned by AGHL, Ali YK or any of their respective affiliates, except for any exceptions or modifications agreed in writing by the Supporting Parties, (iv) any material breach by AIL of any of its covenants and agreements set forth in Sections 4.6 and 4.7 of the Support Agreement that is not cured by AIL within ten (10) business days following receipt of written notice of such breach from a Supporting Party (provided that, if AIL disputes such breach and/or its cure of such breach, the Support Agreement shall not terminate unless and until such breach and failure to cure have been determined by a court in accordance with Section 5.3 of the Support Agreement), (v) the date that is 18 months after the date of the Support Agreement if, as of such date, the Issuer, on the one hand, and AIL and/or its affiliates, on the other hand, have not executed and delivered to each other the Merger Agreement, and (vi) any written agreement of AIL and such Supporting Party to terminate the Support Agreement.

The description of the Support Agreement contained herein is qualified in its entirety by reference to Exhibit G, which Exhibit is incorporated herein by reference.
