Ladies and Gentlemen:

Reference is made to the Agreement and Plan of Merger, dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among Ocean Management Holdings Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands, Ocean Management Merger Sub Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands and a wholly-owned subsidiary of Parent (“Merger Sub”) and Qunar Cayman Islands Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), pursuant to which, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Company (the “Merger”). Capitalized or other terms used and not defined herein but defined in the Merger Agreement shall have the meanings ascribed to them in the Merger Agreement. This letter agreement is being delivered by the undersigned (“Sponsor”) to Parent in connection with the execution of the Merger Agreement.

1. Commitment. The Sponsor hereby commits, subject to the terms and conditions set forth herein, to contribute (or cause to be contributed) (the “Contribution”) to Parent, cash in the amount of US$251,545,202 (such sum, subject to the adjustment pursuant to this Section 1, the “Commitment”), in immediately available funds prior to the Effective Time, in exchange for equity securities of Parent. Such Commitment shall be used by Parent, to the extent necessary, solely for the purpose of (a) funding (or cause to be funded) the Merger Consideration and any other amounts required to be paid pursuant to the Merger Agreement, and (b) paying (or cause to be paid) related fees and expenses, in each case, pursuant to and in accordance with the terms of, and subject to the conditions of the Merger Agreement (which, for the avoidance of doubt, shall not include the Parent Termination Fee). Sponsor may effect the Contribution directly or

indirectly through one or more direct or indirect Affiliates of Sponsor, which shall not be a shareholder of the Company. Sponsor shall not, under any circumstances, be obligated to contribute more than the Commitment to Parent. The amount of the Commitment to be funded under this letter agreement may be reduced in the event that Parent does not require all of the equity with respect to which Sponsor has made the Commitment, but only to the extent that Parent and Merger Sub have sufficient immediately available funds in U.S. dollars, following such reduction, to consummate the Merger and other Transactions contemplated by the Merger Agreement and pay any other amounts required to be paid pursuant to the Merger Agreement and to pay all related fees and expenses.

2. Conditions. The Commitment, including the obligation of Sponsor to fund the Commitment, shall be subject to (a) the execution and delivery of the Merger Agreement by the Company, (b) the satisfaction or waiver by Parent of each of the conditions to Parent’s and Merger Sub’s obligations to consummate the Merger set forth in Sections 7.01 and 7.02 of the Merger Agreement (other than those conditions that by their nature are to be satisfied at the Closing), and (c) either (i) the substantially contemporaneous consummation of the Closing or (ii) the confirmation by the Company to Parent that the Company is ready, willing and able to consummate the Closing.

3. Enforceability. This letter agreement may only be enforced by Parent and none of Parent’s creditors nor any other Person that is not a party to this letter agreement shall have any right to enforce this letter agreement or to cause Parent to enforce this letter agreement, provided that, notwithstanding anything to the contrary contained herein, the parties acknowledge and agree that the Company is an express third-party beneficiary of this letter agreement (including, for the avoidance of doubt, Section 1 and this Section 3) (assuming the Company is entitled to the equitable relief provided under Section 9.08 of the Merger Agreement) and shall be entitled to an injunction or an Order of specific performance (or any other non-monetary equitable remedy) to enforce the terms hereof and to prevent breaches of this letter agreement, in addition to any other remedy at law or in equity, and shall not be required to provide any bond or other security in connection with any such Order or injunction (the “Company Third Party Beneficiary Rights”). Subject to the terms and conditions of this letter agreement, the Company shall have the right to enforce the Commitment directly against Sponsor pursuant to this Section 3 in the Company’s own name irrespective of whether Parent pursues such remedy, and Sponsor further agrees not to oppose the granting of any such injunction, Order, specific performance or other equitable relief on the basis that (i) the Company has an adequate remedy at law or (ii) an award of an injunction, Order, specific performance or other equitable relief is not an appropriate remedy for any reason at law or in equity. Subject to Company Third Party Beneficiary Rights, Sponsor and Parent hereby agree that their respective agreements and covenants set forth herein are solely for the benefit of the other party hereto, in accordance with and subject to the terms of this letter agreement.

4. No Modification; Entire Agreement. This letter agreement may not be amended or otherwise modified, supplemented, terminated or waived without the prior written consent of (i) Parent and Sponsor, and (ii) the Company. Together with the Merger Agreement, the Limited Guarantees, the Support Agreement and the Confidentiality Agreement, this letter agreement and other documents and instruments and other agreements among the parties hereto or thereto as contemplated hereby or thereby or referred to herein or therein constitutes the entire agreement, and supersedes all prior agreements, understandings and statements, written or oral, between Sponsor or any of its Affiliates, on the one hand, and Parent or any of its Affiliates, on the other, with respect to the transactions contemplated hereby and thereby.
