Licensor hereby grants to Licensee, and Licensee hereby accepts from Licensor, an exclusive, non-transferable (except as set forth in Section 10.7) and non-sublicensable (except as provided in Section 2.1(c)) license to use the Licensed Domain Names in connection with the Business during the Term. Except as provided in Section 2.3, Licensee's use of the Licensed Domain Names under the terms of this Agreement shall be free of any fees. (b) Subject to the terms and conditions of this Agreement, Licensor hereby grants to Licensee, and Licensee hereby accepts from Licensor, an exclusive, non-transferable (except as set forth in Section 10.7) and non-sublicensable (except as provided in Section 2.1(c)) license to use the Licensed Content in connection with websites associated with the Licensed Domain Names until the earlier of (i) termination or expiration of this Agreement, or (ii) termination or expiration of the Agency Agreement, provided, however, that in the event the Agency Agreement is amended or restated, such amendment or restatement shall not be deemed a termination or expiration of the Agency Agreement. Except as provided in Section 2.3, Licensee's use of the Licensed Content under the terms of this Agreement shall be free of any fees. (c) Notwithstanding anything in this Agreement to the contrary, Licensee has no right to sublicense any rights granted hereunder to any third party, or otherwise permit any third party to use any Licensed Domain Names or Licensed Content; provided, however, that any rights granted to Licensee hereunder shall be sublicensable, without the prior written consent of Licensor, to SINA Leju and Licensee's Affiliates that are controlled by SINA Leju solely for the purpose of operating the Business during the Term. All rights in and to the Licensed Domain Names and Licensed Content not expressly granted herein are hereby reserved exclusively by Licensor. Licensee shall be responsible for the compliance of the terms and conditions of this Agreement by all of its sublicensees. Without limiting the foregoing, in the event any sublicensee undertakes any action (or inaction) that would be deemed a breach of this Agreement had Licensee taken such action (or inaction), such action (or inaction) shall be deemed a breach by Licensee under this Agreement. 2.2. Other Content. Licensee may desire to use Content other than Licensed Content, from time to time, in connection with the websites associated with the Licensed Domain Names ("Operating Content"). Licensee may independently enter into an agreement with the owner of the Operating Content to secure Licensee's right to use such Operating Content, and shall be solely responsible for the cost and expense associated with procuring such Content. For the avoidance of doubt, Licensee shall be permitted to upload such Operating Content directly onto Licensee's websites or through use of the Licensor's software pursuant to the Software 4 Source: CHINA REAL ESTATE INFORMATION CORP, F-1, 9/29/2009 License Agreement.

For example, if Licensor, prior to the Effective Date, employs ten (10) full time employees dedicated to obtaining Content and, as a result of Licensee's request for Operating Content pursuant to this Section 2.2, must hire an additional full time employee to handle Licensee's request, Licensee shall reimburse Licensor for the costs related to such full time employee, provided that, if such full time employee also engages in work on behalf of Licensor or its Affiliates, Licensee shall reimburse Licensor on a pro rata basis only for the time spent by such full time employee in handling Licensee's requests. Licensee further acknowledges that Licensor has no obligation to fulfill any request by Licensee to procure Operating Content under this Section 2.2. Unless otherwise agreed to by the Parties, any Operating Content obtained on Licensee's behalf by Licensor shall be for Licensee's use only and shall not be used by Licensor or its Affiliates or provided or made available to any third parties by Licensor. 2.3. Fees.
