10.4 语言

Language

本合同以中文和英文书就，一式五份，每一方各持一份，具有同等效力；中英文版本如有冲突，应以中文版为准。

10.5 可分割性

Severability

如果本合同有任何一条或多条规定根据任何法律或法规在任何方面被裁定为无效、不合法或不可执行，本合同其余规定的有效性、合法性或可执行性不应因此在任何方面受到影响或损害。各方应通过诚意磋商，争取以法律许可以及各方期望的最大限度内有效的规定取代那些无效、不合法或不可执行的规定，而该等有效的规定所产生的经济效果应尽可能与那些无效、不合法或不能强制执行的规定所产生的经济效果相似。

In the event that one or several of the provisions of this Agreement are found to be invalid, illegal or unenforceable in any aspect in accordance with any laws or regulations, the validity, legality or enforceability of the remaining provisions of this Agreement shall not be affected or compromised in any respect. The Parties shall strive in good faith to replace such invalid, illegal or unenforceable provisions with effective provisions that accomplish to the greatest extent permitted by law and the intentions of the Parties, and the economic effect of such effective provisions shall be as close as possible to the economic effect of those invalid, illegal or unenforceable provisions.

Waivers

任何一方可以对本合同的条款和条件作出弃权，但必须经书面作出并经各方签字。一方在某种情况下就其他方的违约所作的弃权不应被视为该方在其他情况下就类似的违约已经对其他方作出弃权。

Any Party may waive the terms and conditions of this Agreement, provided that such a waiver must be provided in writing and shall require the signatures of the Parties. No waiver by any Party in certain circumstances with respect to a breach by other Parties shall operate as a waiver by such a Party with respect to any similar breach in other circumstances.
