2                                         Any standing proxy previously deposited by a shareholder with the Company will be voted in favour of the resolutions to be proposed at the AGM unless revoked prior to the AGM or the shareholder attends the AGM in person or executes a specific proxy.

3                                         A form of proxy for use at the AGM is enclosed. Whether or not you propose to attend the AGM in person, you are strongly advised to complete and sign the enclosed form of proxy in accordance with the instructions printed on it and then deposit it (together with any power of attorney or other authority under which it is signed or a notarially certified copy of that power or authority) at the offices of the Company at 17th Floor, Viva Plaza, Building 18, Yard 29, Suzhou Street, Haidian District, Beijing, People’s Republic of China, or send copies of the foregoing by email to qi.guo@qunar.com, in each case marked for the attention of Qi Guo, not later than 48 hours before the time for the holding of the AGM or adjourned AGM in accordance with the Articles of Association of the Company.

For this purpose seniority shall be determined by the order in which the names stand on the Company’s register of shareholders in respect of the relevant shares.

5                                         On a poll, a shareholder holding more than one share entitled to attend and vote at the AGM need not cast the votes in respect of such shares in the same way on any resolution and therefore may vote a share or some or all such shares either for or against a resolution and/or abstain from voting a share or some or all of the shares and, subject to the terms of the instrument appointing any proxy, a proxy appointed under one or more instruments may vote a share or some or all of the shares in respect of which he is appointed either for or against a resolution and/or abstain from voting.

6                                         The quorum for the AGM is one or more shareholders holding in aggregate more than one-half (50%) of the Company’s total voting power represented by issued and outstanding voting shares which carry the right to attend and vote at the AGM, present in person or by proxy or, if a corporation or other non-natural person, by its duly authorised representative or proxy and entitled to vote.
