7.1.11 Party C or its successors or custodians can only partially fulfill or refuse to fulfill the payment obligations under the Business Cooperation Agreement, or the Pledgor and/or Party C can only partially pay off or refuse to pay off the secured obligations; and

7.1.12 Any other circumstances in which the Pledgee cannot or may not be able to exercise its rights against the pledge right.

7.2 Once the Pledgor and Party C know or discover that any situation mentioned in Article 7.1 or any event that may lead to the above situation has occurred, they shall immediately notify the Pledgee in writing accordingly.

7.3 Subject to other provisions of this Agreement (including but not limited to Article 19.1), unless the event of default listed in Article 7.1 has been resolved to the satisfactory of the Pledgee within thirty (30) days from the date of the Pledgee's notice, the Pledgee may issue a notice of default to the Pledgor at any time after the occurrence of the event of default, and exercise all the rights and powers of relief for default that it enjoys according to PRC laws, transaction agreements and the provisions of this Agreement, including but not limited to:

13. Governing Law and Dispute Resolution

13.1 The signing, entry into force, interpretation, performance, modification and termination of this Agreement and the resolution of disputes under this Agreement shall be governed by PRC laws.

13.2 In case of any dispute arising from the interpretation and performance of the provisions of this Agreement, the Parties shall resolve the dispute through sincere negotiation. If the Parties fail to reach an agreement on the resolution of such disputes within thirty (30) days after a Party requests the Parties to resolve the disputes through negotiation, any Party may submit the relevant disputes to Beijing Arbitration Commission for arbitration and resolution according to its then effective arbitration rules. The arbitration shall be conducted in Beijing, and the language of arbitration shall be Chinese. The arbitration award shall be final and binding on the Parties. The arbitration tribunal may rule that Party C's equity interests, assets or properties shall be used to compensate or offset the losses caused to the Pledgee due to other Parties' breach of this Agreement, award compulsory relief for relevant business or compulsory asset transfer, or order Party C to go bankrupt. After the arbitration award comes into effect, any

Exhibit 4.18

Party has the right to apply to the court with jurisdiction to enforce the arbitration award. If necessary, the arbitration institution shall have the right to decide that the defaulting Party immediately terminates the defaults or shall not engage in any behavior that may further expand the losses suffered by the Pledgee before making a final decision on the disputes between the Parties. Courts in Hong Kong, Cayman Islands or other courts with jurisdiction (including the court where Party C resides, or the court where the Party C or Pledgee's principal assets are located shall be deemed to have jurisdiction) also have the right to award or enforce the award of the arbitration tribunal, and have the right to award or enforce temporary relief for Party C's equity interests or property interests, and also have the right to make a ruling or judgment to give temporary relief to the Party initiating arbitration while waiting for the formation of the arbitration tribunal or under other appropriate circumstances, such as ruling or judging that the defaulting Party immediately terminates the defaults, or ruling that the defaulting Party shall not engage in any behavior that may further expand the losses suffered by the Pledgee.

13.3 In case of any dispute arising from the interpretation and performance of this Agreement or when any dispute is being arbitrated, the Parties shall continue to exercise their respective rights and perform their respective obligations under this Agreement, except for the disputed matters.

13.4 After the signing date of this Agreement, if there is any promulgation or change of any Chinese laws, regulations or rules at any time, or the change of interpretation or application of such laws, regulations or rules, the following agreements shall apply: (a) if the change of laws or newly promulgated regulations are more favorable to a Party than the relevant laws, regulations, decrees or regulations in force on the date of signing this Agreement (while the other Parties are not seriously adversely affected), each Party shall apply for the benefits brought by the change or new regulations in time and try its best to get the application approved; or (b) if the economic interests of any Party under this Agreement are seriously adversely affected directly or indirectly due to the above-mentioned legal changes or newly promulgated regulations, this Agreement shall continue to be implemented in accordance with the original terms. Each Party shall use all legal means to obtain the exemption from complying with the change or regulation. If the adverse impact on the economic interests of any Party cannot be solved according to the provisions of this Agreement, after the affected Party notifies other Parties, the Parties shall negotiate in time and make all necessary amendments to maintain the economic interests of the affected party under this Agreement.

14. Force Majeure

14.1 “Force majeure” refers to the unforeseeable, unavoidable and insurmountable events that make one Party of this Agreement partially or completely unable to perform this Agreement. Such events include, but are not limited to,

Exhibit 4.18

earthquakes, typhoons, floods, wars, strikes, riots, government actions, changes in laws and regulations or their application.

14.2 If an event of force majeure occurs, one Party's obligations under this Agreement affected by force majeure will be automatically suspended during the delay period caused by force majeure, and its performance period should be automatically extended, and the extended period is the period of suspension, so that the Party does not need to be punished or take responsibility for it. In case of force majeure, the Parties should immediately negotiate to find a just solution, and make every reasonable effort to minimize the impact.

15. Notice

15.1 All notices and other communications required or allowed to be sent according to this Agreement shall be delivered by special person or sent to the address of such party listed in Annex I by registered mail with prepaid postage and commercial express service. The date when such notices are deemed to be effectively served shall be determined as follows:

15.1.2 If the notice is sent by registered mail with prepaid postage, it shall be deemed to have been effectively delivered on the fifteenth (15th) day after the date on the receipt of the registered mail.

15.2 Each Party may change the receiving address of its notice at any time by sending a notice to other parties according to this article.

16. Severability

If one or more provisions of this Agreement are judged to be invalid, illegal or unenforceable in any aspect according to any laws or regulations, the validity, legality or enforceability of the remaining provisions of this Agreement shall not be affected or damaged in any aspect. The Parties should negotiate in good faith, and strive to replace such invalid, illegal or unenforceable provisions with effective provisions to the maximum extent permitted by law and expected by the Parties, and the economic effects produced by such effective provisions should be as similar as those produced by such invalid, illegal or unenforceable provisions as possible.

17. Annex

The annexes attached hereto shall be an integral part of this Agreement.

18. Effectiveness, Amendment, Change, Supplement and Text

when the Registration Authority completes the relevant registration procedures. The term of this Agreement will expire when the contractual obligations are fully fulfilled or the term of the pledge is terminated according to Article 3.

18.2 Any amendment, change and supplement to this Agreement shall be made in writing and shall come into effect after being signed or sealed by the parties and the government registration procedures (if applicable) are completed.

19.4 Any Party may waive its rights under this Agreement, but such waiver must be made in writing and signed by the Parties.

19.6 The Parties agree to sign in time the documents reasonably needed or beneficial to implement the provisions and purposes of this Agreement, and take further actions reasonably needed or beneficial to implement the provisions and purposes of this Agreement.

Exhibit 4.18

equity in the way specified in this Agreement becomes illegal or violates the laws, regulations or rules, due to the promulgation or change of any PRC laws, regulations or rules, or the change of interpretation or application of such laws, regulations or rules, or the change of relevant registration procedures, the Pledgor and Party C shall immediately take any reasonable actions and/or sign any reasonable agreement or other documents according to the Pledgee's reasonable requirements, so as to: (a) maintain this Agreement and the validity of the pledge right under this Agreement.
